Flattened Brazilian disc and modified ring test methods are attractive methods being simpler compared to the other mode I fracture toughness testing methods on rock cores. The aim of this study is to improve these simple methods to yield fracture toughness values that are close to the ones determined by the suggested methods. ABAQUS finite element program was used to determine stress intensity factors of models with various dimensions. Comparing fracture toughness to the results obtained by semicircular bending method tests (0.94 MPa&amp / #8730 / m for andesite and 0.56 MPa&amp / #8730 / m for marble) and the cracked chevron notched Brazilian disc method tests (1.45 MPa&amp / #8730 / m for andesite and 1.08 MPa&amp / #8730 / m for marble), proper geometrical parameters were investigated by changing diameter, central-hole diameter, and loading angle of Ankara andesite and Afyon marble specimens. Semicircular bending method results were lower than the cracked chevron notched Brazilian disc method results. With flattened Brazilian disc method, the closest results (1.45 MPa&amp / #8730 / m for andesite and 1.12 MPa&amp / #8730 / m for marble) to the suggested method was obtained by 54 mm diameter discs with loading angles between 32.5&deg / and 38.0&deg / and with thicknesses between 19 mm and 34 mm. With modified ring test on andesite, the closest results to the suggested method was obtained by 75 mm diameter discs with 8 mm central-hole diameter and 25&deg / loading angle (1.47 MPa&amp / #8730 / m for andesite and 1.07 MPa&amp / #8730 / m for marble), and with 14 mm central-hole diameter and 16&deg / loading angle (1.50 MPa&amp / #8730 / m for andesite and 1.05 MPa&amp / #8730 / m for marble).

Text in Afrikaans / Die tradisionele Newtoniaanse wetenskapsbeskouing berus op drie basiese aannames, naamlik lineere oorsaaklikheid, reduksionisme en objektiwiteit. Ernstige kritiek word al hoe meer teen hierdie basiese aannames van die Newtoniaanse benadering geopper. Veral vanuit die sistemiese en ekosistemiese benaderings is alternatiewelike denkraamwerke tot hierdie benadering voorgestel. Die mees kontemporere denkraamwerk (epistemologie), naamlik die ekosistemiese benadering, is gebaseer op outonomie, struktuurgedetermineerdheid, attribusie van betekenis en konstruktivisme. Hierdie ekosistemiese beginsels is in hierdie studie gebruik om gevangenisproblematiek (wat tot op hede gekenmerk was deur Newtoniaanse denke) te herkonseptualiseer. Die nuwe konseptualisering is prakties in die psigoterapeutiese proses met gevangenes ge'lllustreer. In hierdie proses is outonomie op drie vlakke (die van gevangene, terapeut en gevangenisstelsel) bevorder. Hierdie konseptualisering skyn dus 'n wetenskaplikverantwoordbare basis te bied waarbinne gevangenisstelsels beskou kan word. / The traditional Newtonian approach to science is based on three fundamental assumtions, namely linear causality, reductionism and objectivity. Serious criticism is increasingly being brought against these fundamental assumptions of the Newtonian approach. Specifically the systemic and ecosystemic approaches have presented alternative ways of thought (epistemology). The mos t contemporary epistemology, namely the ecosystemic approach, is based on autonomy, structure-determinism, attribution of meaning and constructivism. These ecosystemic principles were used in this study to reconceptualize problems associated with prisoners, problems previously approached in a Newtonian way. This new conceptualization was practically illustrated in the psychotherapeutic process with prisoners. In this process autonomy of the prisoner, therapist and the prison system was promoted. This conceptualization present a scientifically justified basis for thinking about correctional systems. / Psychology / M.A. (Sielkunde)

The diploma thesis is focusing on the assessment of the information system and the proposal of its changes in the company AUTOCONT a.s. My thesis describes an analysis of the current state of the company and subsequent proposals to improve the system, which should bring to the company to improve work efficiency. The suggestions for improvement themselves are based on analyzes of the current situation.

This thesis is concerned with cost optimization, choosing the right technology to facilitate the work of management and employees in the company and also improve their financial aspects. From a theoretical point of view describes the work area with a focus on Office 2010 and Office 365 and implementing a related technology. It also states the benefits of choosing one of these office packages. The own solution then presents the information systém tools - office suite and the advantages and disadvantages of each implemented solution.

Utvecklingen inom informationssystem har lett till att allt fler verksamhet villdigitalisera deras arbetsprocesser. Det växande mobila användandet av EnterpriseResource Planning (ERP) på enheter såsom smartphones, tablets och handdatorer harlett till att verksamheter ställer större krav på sina system och leverantörer av dessa.Framtidens ERPsystemmåste fungera mobilt och underlätta arbetet för de anställdaistället för att vara ännu ett ITsystemsom ska lösa organisationens alla utmaningar.Denna fallstudie är gjord hos en grossistverksamhet i Skåne som var mitt iimplementationen av sitt ERPsystem,Microsoft Dynamics. Denna studie harundersökt hur arbetet med verksamhetens affärsprocesser såg ut före och underimplementationen av det nya systemet. Bakgrunden till fallstudien var att undersökaom det fanns korrelation mellan hur väl affärsprocesserna var evaluerade, anpassadeoch hur vällyckad verksamhetens ERPimplementationblev. Fallstudien villundersöka hur processmodellering och Business Process Management (BPM) kanstödja denna slags implementation av mobila ERPsystem.Verksamheten i studien är ett mellanstort säljochdistributionsföretag med kontor på4 svenska orter. Verksamheten påbörjade 2015 en digitalisering av helaorganisationen. ITsystemeti bestod då av flera olika system som anpassats underlängre tid för att integrera med varandra och dela information precis efterorganisationens önskan. Som en del av implementationen valde de att använda ettBusiness Process Modeling verktyg för att introducera och träna användarna avprocesserna i det nya systemet. Implementationsfasen i projektet började i februari2017 och i februari 2019 har verksamheten fortfarande inte fastställt ett Golivedatum.. Medeltiden för en ERPimplementationär 17,4 månader [5]. Då verksamhetenGolivedatum har flyttats räknas det nu som att verksamhetens implementation ärförsenade och över medeltiden.Arbetet med processerna före själva projektstart uppfattas som bristfälligt utifrån BPMdras slutsatsen att förseningen av “Go livedatumet”delvis beror det på att företagetoch organisationen inte har analyserat sina egna processer och har förlitat sig förmycket på att konsultbolaget och RapidValue BPM skulle sköta inlärning ochimplementationen. / The development in information systems has led to an increasing number ofbusinesses wishing to digitize their work processes. The growing mobile use ofEnterprise Resource Planning (ERP) systems on devices such as smartphones andtablets has led businesses to place greater demands on their information systems andsuppliers of these. ERP system in the future must be able to function mobile andfacilitate the work for the employees instead of being another IT system that will solvethe organisation's all challenges.This case study was made at a wholesale company in Skåne, which was in the midstof an ERP implementation with Microsoft Dynamics. This study has investigated howthe work with business processes looked before and during the implementation of thenew system. The background to the case study was to investigate whether there wereany correlation between how well the business processes were evaluated, adapted andhow successful the business's ERP implementation was. The case study aims toinvestigate how process modeling and Business Process Management (BPM) cansupport this kind of implementation of mobile ERP systems.The activity in the study is a mediumsizedsales and distribution company withoffices in 4 Swedish locations. In 2015, the business began digitizing the entireorganization. The IT system consisted of several different systems that had beenadapted over time to fit the needs of the organisation. As part of the implementation,they chose to use a Business Process Modeling tool to introduce the system and trainthe users of the processes in the new system. The implementation phase of the projectbegan in February 2017 and in February 2019 the business still has not set a Golivedate. The average time for an ERP implementation is 17.4 months [5]. Since theGolivedate business has been moved, it is now considered that the operation'simplementation is delayed and over the average time.The work on the processes before the actual start of the project is perceived asinadequate from BPM, the conclusion is drawn that the delay of the "Go live date" ispartly due to the fact that the company and the organization have not analyzed theirown processes and have relied too much on the consulting company and RapidValueBPM to handle learning and implementation.

Denna studie undersöker det växande fenomenet quishing (QR-kod phishing) i ljuset av den ökande användningen av QR-koder under COVID-19-pandemin. QR-koder, som är en lösning för beröringsfri interaktion, har blivit allt vanligare och utnyttjas alltmer frekvent i skadliga phishing-attacker mot företag och deras anställda. Under 2023 observerades en dramatisk ökning på över 2 400 procent i en omfattande quishing-kampanj. Undersökningen granskar tidigare studier och forskning om quishing och framhäver behovet av att öka medvetenheten bland anställda och hur man kan implementera effektiva skyddsåtgärder. En central del av studien inkluderar en enkätundersökning och en Attack Simulation Training (AST) som genomförs i samarbete med en Managed Security Service Provider (MSSP). Målet med undersökningen är att belysa anställdas medvetenhet om quishing, deras reaktioner och vad som ligger till grund för de anställdas agerande. Vidare inkluderar studien ett experiment rörande hur effektivt MDO (Microsoft Defender for Office) och andra säkerhetslösningar upptäcker inbäddade QR-koder i olika bildformat och rörliga animationer i epost. Resultaten från enkätundersökningen och ASTn ger insikter som stärker förståelsen för företagens och de anställdas handlande i förhållande till en av många varianter av phishing.Utifrån detta kan rekommendationer för förbättringar, verktyg och policys för att motverka hotet utvecklas och anpassas till hur det verkliga förhållandet är i dagsläget. Studien strävar efter att bidra till en mer omfattande förståelse av quishing och främja framtidens säkerhetskultur inom företagsmiljöer. / This study explores the rising trend of quishing (QR code phishing) in the context of the increased use of QR codes during the COVID-19 pandemic. QR codes, which facilitate contactless interactions, have become more prevalent and are increasingly exploited in malicious phishing attacks targeting companies and their employees. In 2023, a significant surge of over 2,400 percent was observed in a major quishing campaign. The research reviews previous studies on quishing and underscores the necessity of raising employee awareness and implementing effective protective measures. A key component of the study involves a survey and an Attack Simulation Training (AST) conducted in partnership with a Managed Security Service Provider (MSSP). The objective is to assess employees' awareness of quishing, their responses, and the factors influencing their behavior. Additionally, the study includes an experiment to evaluate how effectively Microsoft Defender for Office (MDO) and other security solutions detect embedded QR codes in various image formats and animations in emails. The findings from the survey and AST provide valuable insights into how companies and employees respond to different types of phishing attacks. Based on these insights, recommendations for improvements, tools, and policies can be developed and tailored to the current threat landscape. The study aims to enhance the overall understanding of quishing and promote a stronger security culture within corporate environments.

Memoria (licenciado en ciencias jurídicas y sociales) / El trabajo pretende una revisión crítica de la denominada “hipótesis represiva” de la sexualidad, centrándose en el rol de la prohibición de la sodomía. La tesis central consiste en plantear que la proscripción de la sodomía no sólo es la manifestación del tabú de la homosexualidad masculina sino que es –también– constitutiva del paradigma falo(go)céntrico en atención al cual la agencia sexual femenina es jurídicamente invisibilizada

Memoria (licenciado en ciencias jurídicas y sociales) / En esta investigación se examinan, desde una perspectiva crítica y analítica, algunas disposiciones vigentes del Código Penal chileno que envuelven consideraciones de género, que han dado origen a diversas posiciones doctrinarias en torno a la posibilidad de que la mujer sea sujeto activo de los mismos. Se analiza en profundidad el caso del delito de femicidio en nuestro ordenamiento, para llegar a afirmar que la redacción escogida por el legislador deja abierta la puerta para sostener que una mujer puede cometer el delito de femicidio en contra de su pareja del mismo sexo. Al efecto, se revisan algunos ejemplos en Derecho comparado, en que se utilizaron modelos diferentes al nacional, que dan lugar a interpretaciones disímiles sobre el particular. Lo anterior adquiere relevancia respecto del Acuerdo de Unión Civil, donde se expone nuestra opinión respecto a la aplicación del delito de femicidio para las convivientes civiles del mismo sexo. Además del delito de femicidio, se analizan otros delitos de nuestro Código punitivo de carácter sexual, específicamente los delitos de violación (artículo 361) estupro (artículo 362) y sodomía (artículo 365), en que existe discusión a nivel doctrinario respecto de admitir o no a la mujer como posible sujeto activo de los mismos. Tras aquello, se fundamenta nuestra postura en cada caso.

Les prisons ouvertes constituent un modèle pénitentiaire singulier, qui puise son origine dans des expérimentations carcérales de la première moitié du XIXème siècle. Leurs caractéristiques et leurs atouts ont été définis en 1955 par la jeune Organisation des Nations-Unies en même temps que fut encouragé leur usage. Malgré ce soutien, les prisons ouvertes ne trouvèrent pas partout le même espace pénologique, ce que le cas français illustre largement par la faible proportion d’utilisation réservée à ces établissements. De plus, l’ultra-minorité des prisons ouvertes françaises s’accompagne de critères d’emploi qui font figures d’exceptions, en comparaison des autres pays européens utilisateurs de ce modèle.Toutefois, la réforme des modalités d’exécution des peines intervenue récemment dans l’hexagone pourrait entrainer une reconsidération de leurs fonctions. La présente recherche propose donc de situer ces établissements dans les nouvelles inflexions qui touchent la pénologie européenne et française, tout en envisageant la place que pourraient être amenées à y trouver les différentes déclinaisons du modèle ouvert de détention / Open prisons constitute a unique model prison, which has its origin in prison experiments of the first half of the nineteenth century. Their characteristics and strengths were identified in 1955 by the young United-nations, when was also encouraged their use. Despite this support, open prisons are not found everywhere the same penological space, as the French low rate of utilization illustrated well. In addition, the ultra-minority of French open prisons and their criteria of employment figure as an exception, in comparison with the other European countries witch use this model.However, the reform of the enforcement sentences system recently intervened in the hexagon could lead to a reconsideration of their use. So this research proposes to locate these facilities in new inflections that affect the European and French penology, while considering the role that could be led to find different versions of the open institution model
