Previous issue date: 2013-06-20 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Considering the importance of the moment of diagnosis notification of a disability to parents due to the baby birth and the burden of this approach by professionals, physicians responsible for this task, the purpose of this study is to understand their emotions and experiences, as well the preparation they had for giving this approach. The method is based on a qualitative procedure, of exploratory feature, using the technique of semi-structured interview in accordance with life and professional experiences related to the subject matter. The survey was conducted with 10 physicists, among Obstetricians and Neonatologists, in the city of São Paulo, SP. The interviews were then analyzed and the results presented and discussed in three different categories: the Disability Notification, Emotions and Professional Preparation. Based on the analysis of the categories, it could be highlighted that the physicists pointed out several issues related to this task. Were marked the inadequate and ineffective approaches, and the lack of preparation and difficulties in bad news statement. Mostly, these troubles were associated with lack of academic preparation regarding these approaches. Further, were discussed the generated emotions and parents reaction facing this notification. / Diante da importância do momento da notificação do diagnóstico de uma deficiência aos pais por ocasião do nascimento do bebê e das dificuldades encontradas para esta abordagem pelos profissionais, médicos responsáveis por esta tarefa, o presente estudo teve como objetivo conhecer seus sentimentos e vivências, assim como o preparo que tiveram para esta abordagem. O método foi pautado em uma abordagem qualitativa, de caráter exploratório, a partir da técnica de entrevista semiestruturada com base nas vivências e experiência profissional relacionada ao tema em questão. A pesquisa foi realizada com 10 médicos, entre Obstetras e Neonatologistas na cidade de São Paulo/SP. As entrevistas foram analisadas e seus resultados apresentados e discutidos em três diferentes categorias: a Notícia da Deficiência, Sentimentos e Preparo Profissional. Com base na análise das categorias, pode-se evidenciar que os médicos apontaram diversas dificuldades em relação a esta tarefa. Foram sinalizadas as abordagens inadequadas e ineficazes, e o despreparo e dificuldades na comunicação das más notícias. Em grande parte estes dificultadores foram associados à falta de preparo acadêmico para estas abordagens. Foram também discutidos os sentimentos gerados nos profissionais, suas vivências e as reações dos pais diante desta notificação.

Desenvolvimento e uso de aplicativo móvel para monitoramento da ocorrência de mordeduras por morcegos hematófagos e suspeitas de raiva em herbívoros no Estado de São Paulo / Development and use of a mobile application to monitor the occurrence of bites by hematophagous bats and suspected rabies in herbivores in the state of São PauloVanessa Cristinne Victor Rabaquim 13 November 2017 (has links)
O monitoramento da população animal é um instrumento imprescindível para o controle de zoonoses e outras doenças. Com o avanço tecnológico, em termos de comunicação, houve o aumento no desenvolvimento de aplicativos móveis. Este trabalho tem com o objetivo desenvolver um aplicativo móvel para o sistema operacional Android® com o propósito de otimizar o sistema de notificação de animais espoliados por morcegos e casos de suspeitas de raiva. Sendo utilizado para o desenvolvimento do aplicativo o Software LiveCode®. O Aplicativo é capaz de se conectar ao banco de dados em um servidor através da Internet móvel ou wi fi, e permite ao proprietário notificar a incidência de mordedura por morcego ou suspeita de raiva no rebanho, e ao médico veterinário visualizar e modificar os dados enviados pelo proprietário da sua região. Diante dos dados obtidos neste trabalho, conclui-se que o aplicativo atende aos objetivos propostos de coletar dados de notificação e otimizar o sistema de notificação. A baixa adesão ao aplicativo, devido a ausência de acesso a Internet pelos proprietários, sugere a necessidade de modificar o sistema de comunicação do aplicativo com o banco de dados. / Monitoring of the animal population is an essential tool for the control of zoonoses and other diseases. With the technological advancement, in terms of communication, there has been an increase in the development of mobile applications. This work aims to develop a mobile application for the Android® operating system for the purpose of optimizing the notification system of bat-bitten animals and suspected rabies cases. LiveCode® Software is used for the development of the application. The application is able to connect to the database on a mobile Internet or wi fi, and allows the owner to report the incidence of bat bitten or suspected rabies in the herd, and to the veterinarian viewing and modifying the data sent by the owner of your region. Based on the data obtained in this work, it is concluded that the application meets the proposed objectives of collecting notification and optimizing the notification system. The low adherence to the application, due to the absence of Internet access by the owners, suggests the need to modify the communication system of the application with the database.

Previous issue date: 2014-07-07 / Objetivos: Para este trabalho foi desenvolvido dois Estudos, objetivando: i) avaliar fatores de risco para o abandono do tratamento da TB, por meio de um estudo de coorte (estudo 1), e ii) comparar a incidência dos desfechos dos tratamentos de um subgrupo de casos prevalentes e incidentes de TB, acompanhado diretamente, com a de outro acompanhado indiretamente, por meio dos registros do departamento de epidemiologia do município (estudo 2). Metodologia: Estudo1: Realizou-se um estudo de coorte envolvendo pacientes notificados com tuberculose em centros de referência, no município Juiz de Fora (JF), Minas Gerais, no período de 2008 a 2009, comparando os que tiveram cura (n=172) com os que abandonaram (n=48). Para avaliar fatores associados ao abandono, utilizou-se modelos teóricos multivariados de determinação com três níveis hierarquizados de variáveis explicativas (distai, intermediário e proximal). As variáveis foram ajustadas entre si dentro de cada nível, aquelas com nível de significância p 0,20 foram transferidas para o nível superior. No modelo multivariado final, as variáveis que não se apresentarem significativas foram removidas até que todas as variáveis do modelo fossem significativas (p 0,05), alcançando um nível de ajuste adequado ao modelo. Estudo 2: Para comparar as incidências de encerramentos dos casos de TB acompanhadas diretamente (n=287) com as de forma indireta (n=216), dentre os notificados (n=503) ao Sistema de Informação de Agravos de Notificação (SINAN), por JF, 2008 a 2009, foi conduzido um estudo de coorte aberto prospectivo. Resultados: Estudol: Do total de encerramentos acompanhados diretamente n=220, 172 (78,2%) e 48 (21,8%) tiveram cura e abandono como encerramentos. No modelo houve uma associação direta entre a intensidade do uso de drogas e a incidência de abandonos, sendo os riscos de abandonos crescentes no sentido ex-usuários (OR= 4,12, 1095% 1,11 — 15,20), usuários de cocaína isolada ou em combinação com maconha (OR= 5,67, IC95% 1,34 — 24,03) e usuários de crack isolado ou combinado com outras drogas (OR=12,25, 1095% 3,04 —49,26). Adicionalmente, Indivíduos que bebem exageradamente tiveram mais risco de abandonar o tratamento que os indivíduos que não beberam no último ano ou bebem de forma moderada (OR= 2,94, 1095% 1,08 — 7,99). Estudo 2: O número/incidência de abandonos foi maior (p<0,05) entre os acompanhados diretamente (53/18,5%), comparado com os acompanhados indiretamente (6/2,8%) e, mesmo com o total notificado ao SINAN (14/2,8%). O risco relativo (RR) de abandono no grupo com acompanhamento direto foi de 6,64 (IC 95% 2,91-15,18). Enfim, verificou-se uma maior incidência de abandonos na população acompanhada diretamente, que, em sua maioria, permaneceu negligenciada ao SINAN. Conclusão: Evidenciou-se a necessidade de medidas efetivas para melhoria do controle da TB e da qualidade dos dados do SINAN-TB e que a tuberculose deve ser vista não só no ponto de vista físico, mas também com a complexa relação com os vários fatores sociais fora da unidade de saúde, os quais devem ser levados em conta tanto na prevenção quanto no tratamento da doença. / Objectives: For this work was conducted two studies, aiming: i) to evaluate risk factors for default TB treatment by means of a cohort study (study 1) and ii) to compare the incidence of the outcomes of a subgroup of prevalent and incident cases of TB, followed directly, with another accompanied by indirectly through the records of the department of epidemiology of the municipality (study 2). Methods: Study1: We conducted a cohort study involving tuberculosis patients in referral centers in the city Juiz de Fora (JF), Minas Gerais, in the period 2008-2009, comparing those who were cured (n = 172) with those who have dropout (n = 48). To assess factors associated with dropout, we used multivariate theoretical models for determining three hierarchical levels of explanatory variables (distal, intermediate and proximal). The variables were adjusted for within each level, those with a significance level of p 0.20 were transferred to the upper level. In the final multivariate model, the variables that do not present significant were removed until all variables in the model were significant (p 0.05), reaching a level appropriate to the model setting. Study 2: To compare the effects of closures of TB cases followed directly (n = 287) with indirect (n = 216) form, among the reported (n= 503) of the Notifiable Diseases Information System (SINAN), by JF, 2008-2009, a prospective open cohort study was conducted. Results: Study1: Of the closures directly tracked n= 220, 172 (78.2%) and 48 (21.8%) were cured and abandonment as closures. In the model there is a direct association between the intensity of drug use and the incidence of dropouts, and increasing the risk of abandonment towards ex-users (OR= 4.12, 95% CI 1.11 to 15.20), cocaine users alone or in combination with cannabis (OR= 5.67, 95% CI 1.34 to 24.03) and crack users alone or combined with other drugs (OR= 12.25, 95% CI 3.04 to 49.26). Additionally, individuals who drink heavily have a higher risk of dropping out of treatment that individuals who drank in the last year or drink moderately (OR= 2.94, 95% CI 1.08 to 7.99). Study 2: The number / incidence of dropouts was greater (p<0.05) between the monitored directly (53/18, 5%) compared with the monitored indirectly (6/2, 8%) and even with the total notified to SINAN (14/2, 8%). The relative risk (RR) of noncompliance with direct monitoring group was 6.64 (95% CI 2.91 to 15.18). Anyway, there was a higher incidence of dropouts in the population monitored directly, which mostly remained neglected to SINAN. Conclusion: Evidenced the need for effective measures to improve TB control and data quality SINAN-TB and TB should be seen not only in the physical point of view, but also with the complex relationship with the various social factors outside the health unit, which must be taken into account both the prevention and treatment of disease.

A NOTIFICAÇÃO DA VIOLÊNCIA, O ATENDIMENTO PSICOLÓGICO E A REDE DE PROTEÇÃO DA CRIANÇA E DO ADOLESCENTE: O OLHAR DE PROFISSIONAIS DO SISTEMA DE GARANTIA DE DIREITOS / NOTIFICATION OF VIOLENCE, PSYCHOLOGICAL ASSISTANCE AND THE NETWORK OF PROTECTION DEVELOPED FOR CHILDREN AND ADOLESCENTS: THE PERSPECTIVE OF PROFESSIONALS WORKING IN THE SYSTEM OF GUARANTEE OF RIGHTSFaraj, Suane Pastoriza 20 March 2014 (has links)
Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / This Master s Thesis discusses the notification of violence, the psychological assistance
provided to children and adolescents who suffer violence and the network of protection for them, from
the perspective of professionals that work in the services of the System of Guarantee of Rights. It is a
qualitative, exploratory and descriptive study, accomplished in the context of the Child and
Adolescent Protection Precinct, Public Prosecutor s Office and three Child Protection Agencies of a
city in Rio Grande do Sul. Three child protection agents, one police chief and one public prosecutor
participated in the study. Semi-structured interviews were used, and analyzed using content analysis.
This thesis is composed of four articles, one theoretical and three empirical. The theoretical article
presents a reflection about the assistance towards the child or adolescent who experienced a situation
of violence in the perspective of the System of Guarantee of Rights. The first empirical article
approaches a comprehension of the network of protection and the way it works in cases involving
violence against children and adolescents. It highlights challenges and possibilities of enforcing the
rights of such population. The second article presents the procedures of the Child Protection Agencies,
Child and Adolescent Protection Precinct and Public Prosecutor s Office after receiving a notification
of violence involving children and adolescents. Moreover, it approaches the advances, hindrances and
challenges regarding the notification of violence. The last article discusses the psychological
assistance provided to children and adolescents facing violence in the context of social assistance
policies. It also presents the perceptions and the perspectives about psychological assistance. Results
suggest that the interviewed professionals understand the network of protection recommended by the
Statute of the Child and Adolescent and its functioning. They highlight the relevance of the joint
efforts in cases involving violence, regarding effectively protecting and promoting the rights of
children and adolescents. Results also indicate several procedures of the defense agencies after the
notification of violence, among them, the referral for psychological services, characterized as a service
through which the subjects are allowed to talk about the violence they suffered, under an atmosphere
of support and protection. Final considerations highlight the importance of strengthening the network
of protection, as well as the need to educate the society about notification, aiming at coping with
violence and protecting children and adolescents. In conclusion, the relevance of training professionals
is emphasized, focusing on the development of integrated and coordinated actions, so as to interrupt
historical practices, in the context of policies and rights towards children and adolescents. / A presente dissertação de mestrado versa sobre a notificação da violência, o atendimento
psicológico oferecido às crianças e adolescentes em situação de violência e a rede de proteção da
população infanto-juvenil, a partir do olhar de profissionais que atuam nos órgãos que compõem o
Sistema de Garantia de Direitos. Trata-se de um estudo de delineamento qualitativo e caráter
exploratório e descritivo, realizado junto à Delegacia de Proteção à Criança e ao Adolescente,
Ministério Público e três Conselhos Tutelares, de um município do Rio Grande do Sul. Participaram
do estudo três conselheiros tutelares, um delegado de polícia e um promotor de justiça. Foram
utilizadas entrevistas semi-estruturadas, as quais foram analisadas por meio de análise de conteúdo.
Esta dissertação é composta por quatro artigos, sendo um teórico e três empíricos. O artigo teórico
apresenta uma reflexão a cerca do atendimento à criança e ao adolescente que vivenciaram uma
situação de violência na perspectiva do Sistema de Garantia de Direitos. O primeiro artigo empírico
apresenta a compreensão da rede de proteção e o funcionamento desta nos casos envolvendo violência
contra a criança e o adolescente. Aponta ainda, os desafios e as possibilidades da efetivação dos
direitos da população infanto-juvenil. O segundo apresenta os procedimentos de órgãos Conselho
Tutelar, Delegacia de Proteção à Criança e ao Adolescente e Ministério Público após o recebimento
de uma notificação de violência envolvendo crianças e adolescentes. E ainda aborda os avanços,
obstáculos e desafios da notificação da violência. O último abarca o atendimento psicológico oferecido
à criança e ao adolescente em situação de violência no âmbito da política de assistência social.
Apresenta ainda, as percepções e as perspectivas quanto ao atendimento psicológico. Os resultados
sugerem que os profissionais entrevistados compreendem a rede de proteção preconizada no Estatuto
da Criança e do Adolescente (ECA) e o seu funcionamento. Apontam a importância do trabalho
conjunto e articulado nos casos envolvendo violência para a efetivação das ações de proteção e
promoção dos direitos. Indicam diversos procedimentos dos órgãos de defesa diante de uma
notificação da violência, dentre eles, o encaminhamento para atendimento psicológico que se constitui
num espaço em que é possível falar sobre a violência e receber apoio e proteção. As considerações
finais destacam a importância do fortalecimento da rede de proteção, assim como, a necessidade de
conscientizar a sociedade a respeito da notificação a fim de possibilitar o enfrentamento da violência e
a proteção da população infanto-juvenil. Por fim, destaca-se a relevância de capacitar os profissionais
para que estes possam desenvolver ações integradas e articuladas e romper com as antigas práticas
presente nos percurso histórico dos direitos e políticas de atenção à infância e adolescência.

Comparison and evaluation of mass video notification methods used to assist Deaf peopleHoorn, Ryno January 2012 (has links)
Magister Scientiae - MSc / In South Africa, Deaf people communicate with one another and the broader community by means of South African Sign Language. The majority of Deaf people who have access to a mobile phone (cell phone) use Short Message Service (SMS) to communicate and share information with hearing people, but seldom use it among themselves. It is assumed that video messaging will be more accessible to Deaf people, since their level of literacy may prevent them from making effective use of information that is disseminated via texting/SMS. The principal objective of the esearch was to explore a cost-effective and efficient mass multimedia messaging system. The intention was to adapt a successful text-based mass notification system, developed by a local nongovernmental organization (NGO), to accommodate efficient and affordable video mass messaging for Deaf people. The questions that underpin this research are: How should video- streaming mass-messaging methods be compared and evaluated to find the most suitable method to deliver an affordable and acceptable service to Deaf people? What transport vehicles should be considered: Multimedia Message Service (MMS), the web, electronic mail, or a cell phone resident push/pullapplication? Which is the most cost effective? And, finally: How does the video quality of the various transport vehicles differ in terms of the clarity of the sign language as perceived by the Deaf? The soft-systems methodology and a mixed-methods methodology were used to address the research questions. The soft-systems methodology was followed to manage the research process and the mixed-methods research methodology was followed to collect data. Data was collected by means of experiments and semi-structured interviews. A prototype for mobile phone usage was developed and evaluated with Deaf members the NGO Deaf Community of Cape Town. The technology and internet usage of the Deaf participants provided background information. The Statistical Package for Social Science (SPSS) was used to analyse the quantitative data, and content analysis was used to analyse the documents and interviews. All of the Deaf participants used their mobile phones for SMS and the majority (81.25%) used English to type messages; however, all indicated that they would have preferred to use South Africa sign language on their mobile phones if it were available. And they were quite willing to pay between 75c and 80c per message for using such a video-messaging service.Of the transport vehicles demonstrated, most Deaf people indic indicated that they preferred to use the SMS prototype (with a web link to the video) rather than the MMS prototype with the video attached. They were, however, very concerned about the cost of using the system, as well as the quality of the sign language videos. / South Africa

Oficina para abordagem ao comportamento suicida Implementação na atenção primária à saúde /Santos, Daniele Cristina Ribeiro dos January 2020 (has links)
Orientador: Rubia de Aguiar Alencar / Resumo: O suicídio é uma das 10 principais causas de morte no mundo. A cada 40 segundos, morre uma pessoa por suicídio, de modo que se tornou um problema de saúde pública e um agravo de notificação compulsória. A maior parte dos suicídios pode ser prevenida, basta observar o grande número de pessoas que esteve em consulta na Atenção Primária durante o prazo de um ano antes do fato. Assim, a identificação precoce do risco de suicídio é um dos fatores de prevenção. O presente estudo tem por objetivo propor e implementar oficinas problematizadoras sobre a abordagem à pessoa em sofrimento psíquico com comportamento suicida para os trabalhadores e gestores dos serviços da Atenção Primária à Saúde. Foi realizada uma pesquisa de natureza qualitativa-quantitativa conduzida por meio do referencial da pesquisa ação que, por sua vez, corresponde a uma estratégia metodológica e técnica que permite estruturar uma investigação social com maior versatilidade na elaboração e execução dos recursos utilizados na investigação. Para organização da oficina – realizada em três encontros – optou-se pela utilização do Arco de Charles Maguerez. Após a transcrição das narrativas e das gravações da oficina, os dados foram analisados segundo o referencial metodológico da Análise de Conteúdo, na vertente representacional e temática de Bardin.

Covid-19 – ett ingenmansland för förskolebarn i utsatthet / Covid-19 – A no-man's land for preschool children at riskAndersson, Frida, Svanteman, Hannah January 2021 (has links)
Forskning visar att risken för våld och utsatthet i hemmet för barn ökar som en konsekvens av ”nedstängningar” under våren 2020 i samband med covid-19. Personal vid förskola och socialtjänst mister insyn i förskolebarns liv när vårdnadshavare håller barn hemma. Utsatta barn hamnar således i – vad i studien benämns vara – ett ingenmansland. Studien syftar till att undersöka hur personal inom förskola respektive socialtjänst uppfattar pandemin påverkat förskolebarns frånvaromönster i relation till upprättade orosanmälningar gällande barn i förskoleålder våren 2020. Data insamlades från förskolerektorer samt socialsekreterare. Materialet analyserades genom konventionell innehållsanalys utifrån Becks teori om risksamhället. Resultaten visar att förskolan i jämförelse med innan pandemin, har lägre grad av insyn i barns liv samtidigt som socialtjänsten inte ser ett pandemirelaterat ökat antal orosanmälningar, snarare ett minskat eller stagnerat inflöde. Resultaten visar att barns utsatthet i hemmet därmed har ökat. Förskolebarn är hemma i högre utsträckning än tidigare, särskilt barn med annat modersmål än svenska, samtidigt som förväntad ökning av orosanmälningar till socialtjänsten uteblivit. Rektorer gjorde inte i högre utsträckning orosanmälningar, trots att de uttryckt en direkt och indirekt ökad oro för barn. Barns hemsituation osynliggörs på så sätt för professionella vuxna, och barnen hamnar mellan skyddsnätet förskola och socialtjänst. / Research shows that the risk of violence and vulnerability in the home for children increases as a consequence of lockdowns related to the covid-19 pandemic. Staff at preschools and social services lose insight into the lives of preschool children when guardians keep their children at home. Vulnerable children thus end up being in a no-man's land. The study aims to investigate how staff in preschool and social services perceive the pandemic affected preschool children's absence patterns in relation to established reports of concerns regarding children of preschool age in the spring of 2020. Data were collected from preschool principals and social workers, analyzed through a conventional content analysis and Ulrich Beck's theory of a risk society. The results show that preschools to a lesser extent than before the pandemic, has insight into children's lives and the social services do not see any pandemic-related increased inflow of reports of concern, rather decreased or stagnated. The study shows that children's vulnerability in the home has increased. Preschool children were at home to a greater extent than before, especially children with a mother tongue other than Swedish, and the annual expected increase in reports of anxiety to the social services did not materialize. Principals have not made more reports of concern, despite the fact that they have expressed a direct and indirect increased concern for children. Children's home situation is made invisible to professional adults, and the children end up in between two important safety nets, preschool and social services.

Congestion Identification in a Radio Access Transport NetworkMontojo Villasanta, Javier, Maqueda Viñas, Manuel January 2014 (has links)
The convergence of mobile services and Internet has brought a radical change in mobile networks. An all IP network architecture, an evolution of the radio access transport network, is required to support new high-bandwidth services. Unfortunately, existing control mechanisms are insufficient to guarantee end users a high quality of experience. However, coordinating radio and transport network resources is expected to yield a more efficient solution. This thesis project investigates the interactions between the congestion avoidance protocols, explicit congestion notification, and the traffic engineering metrics for latency and bandwidth, when using Open Shortest Path First with traffic engineering (OSPF-TE) as a routing protocol. Using knowledge of these interactions, it is possible to identify the appearance of bottlenecks and to control the congestion in the transport links within a radio access transport network. Augmenting a topology map with the network’s current characteristics and reacting to evidence of potential congestion, further actions, such as handovers can be taken to ensure the users experience their expected quality of experience. The proposed method has been validated in a test bed. The results obtained from experiments and measurements in this test bed provide a clear picture of how the traffic flows in the network. Furthermore, the behavior of the network observed in these experiments, in terms of real-time performance and statistical analysis of metrics over a period of time, shows the efficiency of this proposed solution. / Tjänstekonvergensen av Internet- och mobila tjänster har medfört en radikal förändring i mobilnäten. En ”All IP” nätverksarkitektur, en utveckling av radios transportnät. Utvecklingen krävs för att stödja de nya bredbandiga tjänsterna. Tyvärr är befintliga kontrollmekanismer otillräckliga för att garantera användarens kvalitetsupplevelse. Med att samordna radio- och transportnätverkets resurser förväntar man sig en effektivare lösning. Detta examensarbete undersöker samspelet mellan protokoll för att undvika överlast, direkt indikation av överlast och trafikal statistik för fördröjning och bandbredd med trafikstyrning baserat på fördröjning och bandbredd , vid användning av Open Shortest Path First ( OSPF - TE ) som routingprotokoll. Med hjälp av information om dessa interaktioner, är det möjligt att identifiera uppkomsten av flaskhalsar och för att styra trafikstockningar i transportförbindelser inom ett radioaccess transportnät. En utökad topologikarta med nätverkets aktuella egenskaper kommer att reagera på en potentiell överbelastning. Ytterligare åtgärder, till exempel överlämningar, vidtas i mobilnätet för att säkerställa användarens upplevda kvalitet. Den föreslagna metoden har validerats i en testmiljö. Resultaten från experiment och mätningar i denna testmiljö ger en tydlig bild av hur trafikflödena framskrider i nätverket. Beteendet hos nätverket som observeras i dessa experiment, i termer av realtidsprestanda och statistisk analys av mätvärden över en tidsperiod, visar effektiviteten av denna föreslagna lösning.

Kommersiella hyresavtal i förändring : Co-working - En perfekt kompromiss? / Commercial Leases in ChangeHansols, Caroline, Steffensen, Cassandra January 2019 (has links)
Följande rapport kommer redogöra för den hyresrättsliga aspekten på det nya fenomenet co-working.Undersökningen genomförs genom att granska ett antal avtal som används av aktörer på marknaden i Stockholm.Co-working tar sin början i San Fransisco 2005 och har sedan dess vuxit explosionsartat. Konceptet går ut på attupplåta flexibla arbetsplatser i olika former och detta väcker frågeställningen huruvida hyresavtal föreligger. Det ansesföreligga i de fall samtliga rekvisit i 12 kap 1 § JB är uppfyllda. Särskilt intressant är rekvisiten ”hus eller del av hus”och ”upplåts till nyttjande”. Detta p.g.a. att objektet för upplåtelse inte är byggnadstekniskt avskilt och att utrymmet ivissa fall delas med flera andra. Inom ramen för rapporten har fyra olika medlemskapstyper definierats ochundersökningen visar att några av dessa kan anses utgöra hyresavtal, detta innebär att hyreslagens regler ska tillämpaspå medlemskapen. Hyreslagens syfte är att verka som skyddslagstiftning och av vikt blir därför hyresgästernas skydd.Undersökningen har haft särskilt fokus på reglerna om uppsägningstider och indirekt besittningsskydd då dessasannolikt har störst ekonomisk påverkan för inblandade parter. Undersökningen har visat att avtalen som skrivs innehåller flera brister både vad gäller uppsägningstider och indirektbesittningsskydd. Dagens lagstiftning har visat sig flexibel nog att tillämpa på dessa flexibla arbetsplatser. För attaktörerna ska kunna åstadkomma den avsedda flexibiliteten behöver avtalen skrivas om. Ett förslag är att aktörernaskriver avtalen på bestämd tid vilket ger dem möjlighet att tillämpa kortare uppsägningstider. Vidare kan aktörernaavtala bort det indirekta besittningsskyddet genom att inhämta godkännande från hyresnämnden. På detta sätt kanaktörerna fortsätta bedriva verksamheten i enlighet med gällande lagstiftning samtidigt som användarna får tillgångtill lättillgängliga och flexibla hyresavtal för kontorsplatser. / The following thesis will describe the legal aspects of the new phenomena co-working. The study will beimplemented by reviewing a selected number of contracts that are used by actors on the market for co-working inStockholm. Co-working took its form 2005 in San Francisco and has grown rapidly since. The concept is aboutletting flexible workspaces in different shapes and this raises the question if the contracts are to be seen as leaseagreements. This considers be to hand when all four requisites in 12 chapter 1 § JB is fulfilled. Requisites that areespecially interesting is “house or part of house” and “exclusive right to use”. This due to that the object for leasingis not technically separated and that it is sometimes shared by others. In this thesis four different types ofmembership are identified, and the study shows that some of these are to be considered as lease agreements. Thismeans that the memberships have to follow the rental laws (12 chapter JB). The purpose of the rental law is toprotect the tenant that is to be seen as the weaker part. The study has focused on the rules about notification periodsand indirect protection of possession because this could have a large economic impact for the parties involved.The study has shown that the contracts that are used contains several flaws both regarding notification periods andindirect protection of possession. Current legalization has shown to be flexible enough to be applied on these flexibleworkspaces. For the actors to be able to reach the intended flexibility the contracts need to be rewritten. Onesuggestion is that the actors writes the contracts for a designated time that will allow them to use shorter notificationperiods. The actors are also able to create contracts that doesn’t contain indirect protection of possession byobtaining approval from Hyresnämnden. By doing this, the actors are able to operate in accordance with currentlegalization as well as the users are able to have accessible and flexible workspaces.

Data Management Support for Notification ServicesLehner, Wolfgang 17 July 2023 (has links)
Database management systems are highly specialized to efficiently organize and process huge amounts of data in a transactional manner. During the last years, however, database management systems have been evolving as a central hub for the integration of mostly heterogeneous and autonomous data sources to provide homogenized data access. The next step in pushing database technology forward to play the role of an information marketplace is to actively notify registered users about incoming messages or changes in the underlying data set. Therefore, notification services may be seen as a generic term for subscription systems or, more general, data stream systems which both enable processing of standing queries over transient data.
This article gives a comprehensive introduction into the context of notification services by outlining their differences to the classical query/response-based communication pattern, it illustrates potential application areas, and it discusses requirements addressing the underlying data management support. In more depth, this article describes the core concepts of the PubScribe project thereby choosing three different perspectives. From a first perspective, the subscription process and its mapping onto the primitive publish/subscribe communication pattern is explained. The second part focuses on a hybrid subscription data model by describing the basic constructs from a structural as well as an operational point of view. Finally, the PubScribe notification service project is characterized by a storage and processing model based on relational database technology.
To summarize, this contribution introduces the idea of notification services from an application point of view by inverting the database approach and dealing with persistent queries and transient data. Moreover, the article provides an insight into database technology, which must be exploited and adopted to provide a solid base for a scalable notification infrastructure, using the PubScribe project as an example.
