The severity of this injury is directly related to factors associated with the therapy itself and the individual characteristics of each patient. To date, there is no standard treatment protocol for this condition. Therefore, the present study aimed to evaluate clinically and histologically the effect of granulocyte colony-stimulating factor (G-CSF) on the healing of traumatic ulcers produced in the tongue of Wistar rats undergoing RT. The animals were randomly divided into 4 groups: 1) RT + traumatic ulcer + Filgrastim; 2) RT + traumatic ulcer + saline; 3) no RT + traumatic ulcer + Filgrastim; 4) no RT + traumatic ulcer. Filgrastim (r-metHuG-CSF), a recombinant G-CSF, was injected subcutaneously into the animals once daily, beginning 1 day after a single-dose radiation protocol (30 Gy), immediately after the traumatic ulcer was made. At the end of a 7-day experimental period, animals were euthanized and had their tongue surgically removed, processed, and stained with hematoxylin and eosin (HE). Clinically, all groups differed significantly in presence and size of traumatic ulcers, and the irradiated groups also differed significantly in severity of radiation-induced OM. Filgrastim-treated groups, submitted or not to RT, showed a better performance in this aspect. Histologically, there was an increased inflammatory response in the nonirradiated groups, with no statistically significant difference between the study drug and the respective control groups. Based on the present clinical results, we conclude that the use of Filgrastim reduced the manifestation and severity of trauma-induced ulcers and radiation-induced OM. This condition has a complex pathogenesis, which requires further detailed investigations on the actual role of G-CSF in its management before a formal recommendation regarding its use for this purpose can be made. / A mucosite oral (MO) radioinduzida ? um efeito colateral altamente debilitante, que afeta a quase totalidade dos indiv?duos portadores de neoplasias malignas na regi?o de cabe?a e pesco?o, submetidos ? radioterapia (RT). A gravidade desta inj?ria est? diretamente relacionada a fatores pertinentes ? terapia em si e ?s caracter?sticas individuais de cada paciente. N?o h?, at? o momento, um protocolo padr?o para o tratamento desta enfermidade. Sendo assim, o presente estudo objetivou analisar clinica e histologicamente a a??o do fator estimulador de col?nias de granul?citos (G-CSF) em ?lceras traum?ticas confeccionadas na l?ngua de ratos Wistar submetidos ? RT. Os animais foram alocados randomicamente em quatro grupos distintos: 1) RT + ?lcera traum?tica + Filgrastim; 2) RT + ?lcera traum?tica + soro fisiol?gico; 3) sem RT + ?lcera traum?tica + Filgrastim; 4) sem RT + ?lcera traum?tica. O Filgrastim (r-metHuG-CSF), um G-CSF recombinante, foi injetado diariamente nos animais pela via subcut?nea, iniciando um dia depois do protocolo ?nico de irradia??o (30 Gy), imediatamente ap?s a confec??o da ?lcera traum?tica. Uma vez conclu?do o tempo experimental de sete dias, os animais foram eutanasiados e tiveram a l?ngua excisada, processada e corada com hematoxilina e eosina (HE). A avalia??o cl?nica diferiu significativamente entre todos os grupos quanto ? presen?a e ao tamanho da ?lcera traum?tica, al?m do grau de severidade da MO radioinduzida, entre os grupos irradiados. Os grupos tratados com Filgrastim, submetidos ou n?o ? RT, apresentaram uma melhor performance neste quesito. Histologicamente, houve maior resposta inflamat?ria nos grupos n?o irradiados, sem diferen?a estatisticamente significante entre a medica??o estudada e os respectivos grupos controle. Baseado nos resultados cl?nicos encontrados, pode-se concluir que o uso do Filgrastim reduziu a manifesta??o e o grau de severidade da ?lcera confeccionada e da MO radioinduzida. Esta ? uma doen?a de patogenia complexa, a qual necessita investiga??es mais detalhadas sobre o real papel do G-CSF no seu manejo, para que uma indica??o formal do seu uso possa ser recomendada com esta finalidade.

O objetivo geral deste estudo consistiu em avaliar a Qualidade de Vida, a Imagem Corporal e a Autoestima em pacientes com c?ncer de cabe?a e pesco?o do munic?pio de Natal-RN candidatos ? reabilita??o prot?tica. Realizou-se um estudo do tipo transversal. Para a coleta de dados foi utilizado o Question?rio sociodemogr?fico, o Question?rio de avalia??o da Universidade de Washington, a Escala de Investimento Corporal, a escala de Autoestima de Rosenberg e a Escala de Ansiedade e Depress?o Hospitalar. A amostra foi constitu?da por 10 pacientes (06 homens e 04 mulheres), com idade entre 35 e 82 anos. Os resultados obtidos mostraram que as melhores pontua??es na escala UW-QoL foram no dom?nio Ombro. As piores pontua??es foram no dom?nio Mastiga??o para os homens e dom?nio Fala para as mulheres. Dentre os dom?nios da Escala de Investimento Corporal, o dom?nio Cuidado corporal apresentou diferen?a significativa entre os homens e mulheres, apontando que as mulheres ap?s o tratamento do CCP exercem um maior cuidado sobre o pr?prio corpo. A autoestima dos participantes da pesquisa foi classificada entre m?dia e alta, indicando a exist?ncia de autovalor positivo, n?o havendo diferen?a significativa entre homens e mulheres. Houve correla??o significativa entre a Qualidade de vida geral e a Imagem corporal, apontando que quanto melhor a qualidade de vida, melhor a rela??o com a imagem do corpo. Atrav?s desse estudo foi poss?vel observar que para os pacientes com c?ncer de cabe?a e pesco?o os aspectos funcionais s?o os mais significativos para a obten??o de uma melhor QV, bem como que existe rela??o entre a imagem corporal e a qualidade de vida nestes pacientes. / The head and neck cancer, as well as its treatment, cause major aesthetic and basic functions changes for the patient and may cause changes in Quality of Life, Body Image and Self- Esteem. The aim of this study was to evaluate the Quality of Life, Body Image and Self- Esteem in patients with head and neck cancer in the city of Natal-RN candidates for prosthetic rehabilitation. We conducted a cross-sectional study. For data collection was used a sociodemographic questionnaire, the University of Washington?s evaluation questionnaire, the Body Investment Scale, the Rosenberg?s Self-esteem scale and the Hospital Anxiety and Depression Scale. The sample consisted of 10 patients (06 men and 04 women), aged between 35 and 82 years old. The results showed that the best scores at UW-QoL scale were in the shoulder area. The worst scores were in the chewing area for men and speech area for women. Among the areas of Investment Body Scale, body care domain showed a significant difference between men and women, noting that after treatment of CCP women exercise greater care over their own bodies. The self-esteem of survey participants ranked among medium and high, indicating the existence of positive self-worth, with no significant difference between men and women. There was a significant correlation between the overall quality of life and body image, indicating that the better the quality of life, the better the relationship with body image. Through this study it was observed that for patients with head and neck cancer, the functional aspects are the most significant to achieve a better QoL, and that there is a relationship between body image and quality of life in these patients.

Trata-se de um rob? provido de duas rodas, acionadas de forma diferencial, dois bra?os, com 5 graus de liberdade cada, um cintur?o de sonares e uma cabe?a est?reo. Como objetivo principal do projeto Robosense, o rob? dever? ser capaz de navegar por todo o pr?dio do LECA, desviando de obst?culos. O sistema de navega??o do rob?, respons?vel pela gera??o e seguimento de rotas, atuar? em malha fechada. Ou seja, sensores ser?o utilizados pelo sistema com o intuito de informar ao rob? a sua pose atual, incluindo localiza??o e a configura??o de seus recursos. Encoders (sensores especiais de rota??o) foram instalados nas rodas, bem como em todos os motores dos dois bra?os da cabe?a est?reo. Sensores de fim-de-curso foram instalados em todas as juntas da cabe?a est?reo para que seja poss?vel sua pr?-calibra??o. Sonares e c?meras tamb?m far?o parte do grupo de sensores utilizados no projeto.

Twenty-five patients with skeletal class III dentofacial deformities (10 men, 15 women; mean age, 29.28 ? 8.22 years; range 18-48 years) were included in this prospective clinical study. Lateral cephalographs were taken in natural head position (NHP) 2 weeks before and 6 months after orthognathic surgery. The reproducibility of the radiographer?s technique of taking radiographs in NHP was investigated using a photographic method and found to be acceptable. All measurements for cervical lordosis (CV1/CV2; CV3/CV7; CV1/CV7), head posture (NSL/OPT; NSL/VER) and other cephalometric values (NSL/Go-Gn; NSL/Ocl; Overjet) were repeated three times by the same investigator at 2- week intervals and the average values of the three measurements were calculated to use in statistical analysis. Intraclass correlation coefficients (ICC) ranged between 0.996 to 1.000, demonstrating a high reliability of the measures. Statistically significant differences were found for CV3/CV7 (P=0.006) and CV1/CV7 (P=0.005) and no significant differences were identified in head posture for both cranio-cervical and cranio-vertical angles. The null hypothesis was rejected. Orthognathic surgery resulted in significant cervical lordosis extension, and a tendency for head extension could also be observed. / O objetivo deste estudo foi avaliar, por hip?tese nula, a lordose cervical e as altera??es da postura da cabe?a usando telerradiografias de perfil ap?s cirurgia ortogn?tica bimaxilar para corre??o de prognatismo mandibular.

As radiografias laterais dos pacientes foram obtidas na posi??o natural de cabe?a (PNC) 2 semanas antes e 6 meses ap?s a cirurgia ortogn?tica. A reprodutibilidade da t?cnica do radiologista para realizar as tomadas radiogr?ficas na PNC foi investigada usando um m?todo fotogr?fico e considerada aceit?vel. As medidas para lordose cervical (CV1/CV2; CV3/CV7; CV1/CV7), postura da cabe?a (NSL/OPT; NSL/VER) e outros valores cefalom?tricos (NSL/Go-Gn; NSL/Ocl; Overjet) foram repetidas tr?s vezes pelo mesmo investigador em intervalos de 2 semanas e os valores m?dios das tr?s medidas foram calculados para serem usados na an?lise estat?stica. Os coeficientes de correla??o intraclasse (ICC) variaram entre 0,996 e 1,000, demonstrando uma alta confiabilidade das medidas. Foram encontradas diferen?as estatisticamente significativas para CV3/CV7 (P=0,006) e CV1/CV7 (P=0,005). N?o foram identificadas diferen?as significativas na postura da cabe?a para os ?ngulos cr?nio-cervical e cr?niovertical. A hip?tese nula foi rejeitada. A cirurgia ortogn?tica resultou em aumento significativo da lordose cervical (extens?o) e tamb?m em uma tend?ncia ? extens?o da postura da cabe?a.

Radiotherapy, whether associated or not with chemotherapy, is the therapeutic modality most often used for cancer of the head and neck. However, it can trigger reactions at the oral level, such as oral mucositis, the most limiting side effect, with intense pain and difficulty eating, which may require the suspension of oncologic treatment for the patient. Polyhexanide has been used effectively and safely in the treatment of acute and chronic wounds. Objectives: To describe the clinical-epidemiologic profile and investigate the efficacy of polyhexanide in the treatment of oral mucositis and pain relief, in the period of 8-15 days, among patients with cancer of the head and neck undergoing treatment with radiotherapy (whether associated or not with chemotherapy). Methods: A randomized clinical trial was conducted, parallel and double-blind, among patients with cancer of the head and neck undergoing radiotherapy treatment with or without chemotherapy, in the High Complexity Oncology Unit of Feira de Santana, Bahia, who developed oral mucositis, were 18 years of age or older and consented to participation and signed informed consent forms in the period of July 2015 to May 2016. Two equal groups were formed by random allocation?an intervention group (polyhexanide gel) and a control group (gel without polyhexanide). These groups were reevaluated after 8 and 15 days of use of the gels. Clinical exams, evaluations of the medical records, and interviews with the application of a survey instrument used in the study were approved by the Committee for Ethics in Human Subjects Research of the State University of Feira de Santana, under the number 1.074.479/2015. Statistical analysis consisted of relative and absolute frequencies, averages, medians, and standard deviation, and the p-value?considered statistically signification when <0.05?were obtained by non-parametric Friedman tests, Wilcoxon the posts with signs and Wilcoxon-Mann-Whitney. Results: The findings were presented as an article. The mean age was 59.68 years; 58.8% men; 67.6% Brown/Black, and 79.4% with an elementary school education or less. The majority of tumors (64.7%) already presented in advanced stage, and the most frequent were those of the pharynx (23.5%) and the oral cavity (20.4%). Radiotherapy associated with chemotherapy was the most used therapy. Grades III and IV of oral mucositis were the most frequent in the third and fourth weeks of radiotherapy treatment. A total of 34 individuals were accompanied, 17 in the intervention group and 17 in the control group. After a period of 8 to 15 days, statistically significant differences were observed (p<0.05) in relation to the reduction in severity of the oral mucositis and pain, between the time points of gel use in the intervention group. Conclusions: Knowledge of the clinical-epidemiologic profile of patients undergoing oncology treatment with oral mucositis is important to establish potentially effective treatments. In this study polyhexanide represented an effective therapy in the treatment of oral mucositis and relief of pain, with positive results in the first 8 days of use. / As neoplasias malignas representam uma das principais causas de morbimortalidade no Brasil e no mundo. A Radioterapia, associada ou n?o a quimioterapia, ? a modalidade terap?utica mais empregada para o c?ncer de cabe?a e pesco?o. Todavia, pode desencadear rea??es em n?vel bucal, como a mucosite oral, o efeito mais limitante, com dor intensa e dificuldades na alimenta??o, podendo requerer at? a suspens?o do tratamento oncol?gico do paciente. A polihexanida tem sido empregada no tratamento de feridas agudas e cr?nicas, com efic?cia e seguran?a. Objetivos: Descrever o perfil cl?nico-epidemiol?gico e investigar a efic?cia da polihexanida no tratamento da mucosite oral e do al?vio da dor, no per?odo de 8 e 15 dias, em pacientes com c?ncer de cabe?a e pesco?o, sob tratamento com radioterapia associada ou n?o a quimioterapia. M?todos: Realizou-se um ensaio cl?nico randomizado, paralelo e duplo cego, com todos os pacientes com c?ncer de cabe?a e pesco?o sob tratamento com radioterapia associada ou n?o a quimioterapia, na Unidade de Alta Complexidade em Oncologia de Feira de Santana, Bahia, que desenvolveram mucosite oral, tinham 18 anos ou mais de idade e aceitaram participar assinando o termo de consentimento livre e esclarecido, no per?odo de julho de 2015 a maio de 2016. Dois grupos foram igualmente formados por aloca??o aleat?ria, o de interven??o (gel de polihexanida) e o grupo controle (gel sem polihexanida), e reavaliados nos intervalos de 8 e 15 dias de uso dos g?is. Avalia??es cl?nicas, de prontu?rios e entrevistas com aplica??o de formul?rio foram aplicadas neste estudo aprovado pelo Comit? de ?tica em Pesquisa com Seres Humanos da Universidade Estadual de Feira de Santana sob o n?mero 1.074.479/2015. Para a an?lise estat?stica empregaram-se as frequ?ncias relativas e absolutas, m?dias, medianas e desvio-padr?o, e o valor de p, considerado estatisticamente significativo quando ? 0,05 foi obtido por meio dos testes n?o param?tricos de Friedman, Wilcoxon dos postos com sinais e Wilcoxon-Mann-Whitney. Resultados: Os achados foram apresentados em forma de artigo. A m?dia de idade foi de 59,68 anos; 58,8% homens; 67,6% de cor parda e 79,4% analfabetos ou com baixo grau de escolaridade. A maioria (64,7%) dos tumores j? se apresentava em est?dio avan?ado, sendo os mais frequentes os da faringe (23,5%) e cavidade oral (20,4%). A Radioterapia associada ? quimioterapia foi a terap?utica mais empregada. Graus III e IV de mucosite oral foram mais frequentes nas 3? e 4? semanas de tratamento radioter?pico. Um total de 34 indiv?duos foi acompanhado, sendo 17 do grupo de interven??o e 17 do grupo controle. Ap?s um per?odo de 8 e 15 dias, observaram-se diferen?as estatisticamente significativas (p<0,05) em rela??o a redu??o da gravidade da mucosite oral e da dor, entre os tempos de uso do gel no grupo de interven??o. Conclus?es: O conhecimento do perfil cl?nico-epidemiol?gico de pacientes em tratamento oncol?gico com mucosite oral faz-se importante para se estabelecer terap?uticas potencialmente eficazes. Neste estudo a polihexanida apresentou-se como uma terap?utica eficaz no tratamento da mucosite oral e controle da dor, com resultados positivos ainda nos primeiros 8 dias de uso.

Headaches are one of the symptoms of stress, a risk factor for psychopathological conditions, school absenteeism and difficulties in relationships, affecting quality of life. This study analyzed stressors and coping in relation to quality of life among adolescents experiencing headaches. A total of 54 adolescents (85.19% girls), aged from 14 to 18 years old and attending elementary, middle or high school in a public school in Sorocaba, SP, Brazil, participated. The following instruments were applied in classrooms: a) to characterize the sample ? Headache Questionnaire; a Characterization Interview Protocol developed for this study; and the Brazil Economic Criteria Classification; b) the Adolescent Perceived Events Scale (APES) was applied to identify stressors during adolescence; c) to assess coping with stressful events during adolescence ? Coping Scale (CS), with 12 coping families using the Motivational Theory of Coping; d) Responses to Stress Questionnaire ? Headache (RSQ-H) with authorized linguistic validation was used to analyze headache stressors and coping: and e) Quality of Life Headache - Youth Questionnaire (QLH-Y) was used to assess quality of life. Descriptive statistics, comparisons between groups and correlations were used in addition to network analyses. Daily headaches were prevalent in 42.59% of the sample, while 29.63% reported headaches several times a week associated with emotional triggers, such as feeling anxious or having concerns. The results showed that girls presented: a) greater perception of good and bad stressors (APES); b) Involuntary Engagement, Rumination, Emotional Excitement and Cognitive Interference (RSQ-H); c) Less Vital Strength and more Depression (QLH-Y). Daily headaches were related to a) stressful events during adolescence (APES), maladaptive coping, isolation and helplessness (CS); b) greater quantity of headache stressors (RSQ-H); c) Disengagement and Avoidance (RSQ-H); d) Depression (QLH-Y). The adolescents receiving medical care more frequently presented: a) positive headache coping with Emotional regulation, Emotional Expression, Secondary Control Engagement, Positive Thinking, Acceptance and Immobilization; b) Harmonization and Vital Strength (QLH-Y). Adolescents with a medical diagnosis of migraines presented: a) a lower perception of bad events (APES); b) greater Helplessness when coping with stressful events during adolescence (CS). Adolescents with headaches that last more than 24 hours more frequently presented: a) Involuntary Engagement; Emotional Excitement and Escape (RSQ-H); b) Fatigue (QLH-Y). These involuntary stress responses and maladaptive coping strategies, especially among girls, show difficulty in self-regulating when facing headache stressors, emphasizing the importance of prevention and the development of more efficient and specific interventions for this age range. Analyses helped understand the processes involved in headache coping among adolescents, showing how somatic symptoms, depression and stress and the impact of headaches on daily life are related. / A adolesc?ncia ? um per?odo do desenvolvimento em que ocorrem transforma??es f?sicas, emocionais e sociais, tornando o adolescente exposto ao estresse. Este tem como um dos sintomas as queixas de dor de cabe?a, que s?o fator de risco para quadros psicopatol?gicos, absente?smo escolar e dificuldades nos relacionamentos, afetando a qualidade de vida. Esta pesquisa analisou os eventos estressores e seu enfrentamento em suas rela??es com a qualidade de vida, em adolescentes com queixas de dor de cabe?a. Participaram 54 adolescentes (85,19% meninas), com 14 a 18 anos, cursando o final do Ensino Fundamental e o Ensino M?dio em uma escola p?blica de Sorocaba-SP. Foram aplicados na sala de aula os instrumentos: a) para caracteriza??o da amostra - Question?rio de Queixa de Dor de Cabe?a; Protocolo de Entrevista de Caracteriza??o, especialmente elaborado; e Crit?rio de Classifica??o Econ?mica Brasil; b) para identifica??o de estressores da adolesc?ncia: Adolescent Perceived Events Scale (APES); c) para avalia??o do enfrentamento de situa??es estressantes da adolesc?ncia: Escala de Coping (EC), com 12 fam?lias de coping, segundo a Teoria Motivacional do Coping; d) para an?lise dos estressores da dor de cabe?a e seu enfrentamento: Responses to Stress Questionnaire ? Headache (RSQ-H), com valida??o lingu?stica autorizada pelos autores; e) para avalia??o da qualidade de vida: Quality of Life Headache - Youth Questionnaire (QLH-Y). Foram feitas an?lises estat?sticas descritivas, de compara??es entre grupos e de correla??es, al?m de an?lise de redes. Houve preval?ncia de dores di?rias em 42,59% da amostra e v?rias vezes por semana em 29,63%, com crises associadas a gatilhos emocionais, como sentir-se ansioso e ter preocupa??es. Os resultados mostraram que as meninas apresentaram: a) maior percep??o de estressores bons e ruins (APES); b) Coping de Engajamento Involunt?rio, Rumina??o, Excita??o Emocional e Interfer?ncia Cognitiva (RSQ-H); c) menos For?a Vital e mais Depress?o (QLH-Y). A dor de cabe?a di?ria estava relacionada a: a) situa??es estressoras da adolesc?ncia (APES), coping mal adaptativo, Isolamento e Desamparo (EC); b) maior quantidade de estressores da dor de cabe?a (RSQ-H); c) Coping de Desengajamento e Evita??o (RSQ-H); d) Depress?o (QLH-Y). Os adolescentes em atendimento m?dico apresentaram mais: a) enfrentamento positivo da dor de cabe?a, com Regula??o Emocional, Express?o Emocional, Coping de Engajamento de Controle Secund?rio, Pensamento Positivo, Aceita??o e Paralisa??o; b) Harmonia e For?a Vital (QLH-Y). Os adolescentes com diagn?stico m?dico de enxaqueca apresentaram: a) menor percep??o de eventos ruins (APES); b) maior Desamparo no enfrentamento das situa??es estressantes da adolesc?ncia (EC). Os adolescentes com dor de cabe?a por mais de 24 horas apresentaram mais: a) Engajamento Involunt?rio, Excita??o Emocional e Fuga (RSQ-H); b) Fadiga (QLH-Y). Essas respostas de estresse involunt?rias e de coping mal adaptativo, especialmente nas meninas, mostram as dificuldades de autorregula??o diante de estressores da dor de cabe?a, alertando para a import?ncia da preven??o e a elabora??o de interven??es mais eficientes e espec?ficas para essa faixa et?ria. As an?lises realizadas auxiliaram na compreens?o dos processos envolvidos no enfrentamento da dor de cabe?a em adolescentes, evidenciando como sintomas som?ticos, depress?o e estresse e o impacto da dor de cabe?a na vida di?ria se relacionam.

Ce travail sur le broyage micronique de la dolomie a permis d'étudier le comportement de deux nouveaux broyeurs: le broyeur RSK LAB 10-25 MATTER PARTNER à billes humides (broyeur à circulation forcée) et le broyeur alpine AFG 100-50 ATP (voie sèche à jets d'air). L'étude sur le broyage par voie humide a permis d'apprécier la grande efficacité de ce broyeur. Les paramètres essentiels sont la vitesse de rotation et le débit d'alimentation. Les granulométries grossières présentent une réaction de broyage du premier ordre et un broyage non linéaire en fonction du temps. Les granulométries fines ne présentent pas de reaction du premier ordre, mais un broyage linéaire en fonction du temps. Une méthode de dimensionnement, derivée de la méthode Mac Cabe et Thiele a été proposée. Les dispersants industriels jouent un rôle essentiellement rhéologique et favorisent l'action de broyage. Dans le cas de la dolomie le polyacrylate de sodium a un effet plus important que le polynapthalène sulfonate de sodium. L'étude du broyeur à jets d'air a mis en évidence le couple prépondérant: Vitesse du sélecteur-pression de broyage. Quelle que soit la nature du broyage, nous n'avons pas observé de modifications importantes quant aux propriétés physico-chimiques de la dolomie. L'obtention des poudres ultrafines relève d'un processus de division et la réactivité des produits peut être reliée totalement au développement de la surface

In the 21st century is still more and more emphasis laid on the phenomenon of Business Process Management. In a great number of corporations it plays the key role, because it makes the overall performance of the organization more effective and it is able to react flexibly in the rapidly changing environment. The main purpose of this graduation thesis is to get the reader to know the meaning of the notion "business architecture -- its structure and roles in the process management. The main task is to design business architecture of the specific field of business and try to implement it in the real and existent or emerging company subjects, offering the real-estate services. As a result of this, we prove the usefulness of the process management and business architecture as a key factor of reaching the effectivity in dynamic, rapidly changing and competitive environment. The thesis is divided into two parts. The theoretical part provides us with methodical data and the practical part with the design of business architecture of a subject, actively operating in the real-estate market. Graphical figures are also the part of the thesis using CABE tool ProVision by Metastorm Corporation.
