We focused on the peer relationship of adolescent patients with schizophrenia, which usually occurs around puberty. Reviewing cases with schizophrenia and the literature extensively, we had come to the conclusion as follows；1) the most robust predictors among factors influencing the prognosis of schizophrenia are premorbid interpersonal relationship and adaptive functions. 2) Especially teachers’ reports about school life and peer relationship during school life are useful for predicting the occurrence of schizophrenia in adolescents. We described characteristic and behavioral childhood features which are important in pathogenesis of schizophrenia, based on high-risk studies and long term follow-up studies. Also, pathological profiles of the interpersonal relationship and pathology in adulthood were presented. We tried to integrate various aspects of interpersonal and social weaknesses of schizophrenics applying 'primary and secondary socialization' concept. Finally, five cases of adolescent schizophrenics were described briefly and proposal for the early detection and intervention for risk factors was introduced.

This study has a purpose to provide information to help develop nursing intervention for demented elderly staying at home. For this purpose I analysed the relationship of patients' disturbing behaviors with their demographic and social characteristics, premorbid personality, and present environmental characteristics through questionnaire survey on their family members. The survey was performed through direct interview, telephone contact. and mail in the regions of Pusan and Gyeongnam. Among family members contacted. 112 ones made an appropriate response to the survey. The statistical package SAS was utilized for descriptive statistics, correlation coefficients, stepwise multiple regression, and cluster analysis. The results of the study were as follows: 1) Demographic and social characteristics of the patients surveyed are female 81.3%, average age 81.4 years, lack of schooling 83.0%, spouse dead 73.2%, having no other disease 58.9%, average duration of dementia 3.8 years, no medical treatment for dementia 84.8%, good married life 40.2%, and primary care given by daughter-in-law 49.1%. 2) Aggressive Psychomotor Behavior(APB) was observed in a way statistically meaningful in case that primary care was given by daughter-in-law, while Nonaggressive Psychomotor Behavior(NPB) was in case of good married life and primary care given by other than daughter-in-law and spouse. Verbally aggressive behavior (VAB) was observed in groups of female, spouse dead, bad married life, and daughter-in-law's primary care. As for Passive Behavior(PB), it was observed in case that patients had educational background of not less high than middle school and that they were having medical treatment. Functionally Impaired Behavior(FIB) was observed in age group of 60-69 and more than 90, in patients' group having no other disease, and in case that the duration of dementia was not less than 5 years. 3) Premobid Neuroticism(N) showed positive correlation with APB and VAB, while Openness (O) did negative correlation with PB. Agreeableness (A) was proved to have positive correlation with PA and FIB, but to have negative correlation with APB and VAB. In addition, Conscientiousness(C) showed negative correlation with APB and VAB. 4) The worse the psychosocial environment was, the more NPB and VAB were observed. 5) APB was explained 24% by C and primary care-giver, while NPB was explained 28% by psychosocial environment, having other disease or not, and married life. VAB was explained 40% by A. sex, and married life. On the other hand PB was explained 33% by O, A. N, and having medical treatment or not. But any significant factor was not found to explain FIB. 6) A cluster analysis was performed on disturbing behaviors of demented elderly staying at home. It enabled to regroup the demented elderly in 5 patterns: high scored in NPB, high scored in FIB. high scored in NPB and VAB, moderately scored in most disturbing behaviors, and low scored in all areas. In conclusion, disturbing behaviors of demented elderly not only reflect their premorbid personality in the past, but also are affected by their present psychosocial environment. Therefore, it is necessary to encourage and respond them with understanding their disturbing behaviors in relation to their past premorbid personality. In addition, it is important to provide them better psychosocial environment in order to reduce their disturbing behaviors.

As rapid progress of population aging and strong interest in health, the demand for new healthcare service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing metabolic syndrome such a lifestyle disease, because the cause of metabolic syndrome is related to life habit. As the advent of ubiquitous technology, patients with the metabolic syndrome can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefore, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing metabolic syndrome. For example, Kim et al.(2010) have proposed a healthcare model for providing the customized calories and rates of nutrition factors by analyzing the user's preference in foods. Lee et al.(2010) have suggested the customized diet recommendation service considering the basic information, vital signs, family history of diseases and food preferences to prevent and manage coronary heart disease. And, Kim and Han(2004) have demonstrated that the web-based nutrition counseling has effects on food intake and lipids of patients with hyperlipidemia. However, the existing researches for u-healthcare service focus on providing the predefined one-way u-healthcare service. Thus, users have a tendency to easily lose interest in improving life habit. To solve such a problem of u-healthcare service, this research suggests a u-healthcare recommender system which is based on collaborative filtering principle and social network. This research follows the principle of collaborative filtering, but preserves local networks (consisting of small group of similar neighbors) for target users to recommend context aware healthcare services. Our research is consisted of the following five steps. In the first step, user profile is created using the usage history data for improvement in life habit. And then, a set of users known as neighbors is formed by the degree of similarity between the users, which is calculated by Pearson correlation coefficient. In the second step, the target user obtains service information from his/her neighbors. In the third step, recommendation list of top-N service is generated for the target user. Making the list, we use the multi-filtering based on user's psychological context information and body mass index (BMI) information for the detailed recommendation. In the fourth step, the personal information, which is the history of the usage service, is updated when the target user uses the recommended service. In the final step, a social network is reformed to continually provide qualified recommendation. For example, the neighbors may be excluded from the social network if the target user doesn't like the recommendation list received from them. That is, this step updates each user's neighbors locally, so maintains the updated local neighbors always to give context aware recommendation in real time. The characteristics of our research as follows. First, we develop the u-healthcare recommender system for improving life habit such as poor eating habits and physical inactivity. Second, the proposed recommender system uses autonomous collaboration, which enables users to prevent dropping and not to lose user's interest in improving life habit. Third, the reformation of the social network is automated to maintain the quality of recommendation. Finally, this research has implemented a mobile prototype system using JAVA and Microsoft Access2007 to recommend the prescribed foods and exercises for chronic disease prevention, which are provided by A university medical center. This research intends to prevent diseases such as chronic illnesses and to improve user's lifestyle through providing context aware and personalized food and exercise services with the help of similar users'experience and knowledge. We expect that the user of this system can improve their life habit with the help of handheld mobile smart phone, because it uses autonomous collaboration to arouse interest in healthcare.

The purpose of this study is to acquire the information on the current situation of students' selection process in order to renovate the system of picking up the students. As a first step of the study, we examined the validity of the factors of the single-out system such as qualification and the process for the application and the standards and proceeding of the selection. Then we analysed the result of the entrance examination of Hansung Science Highschool in 2002. The analysis was on the correlation between the result of entrance examination and the achievement in the school and the decision of the course after graduation. To know on the achievement of the students, we investigated the records of regular tests and asked the teachers' opinion in math and science classes. As a result, we gained the following points: First, the present single-out system has a danger of excluding students who are much talented in science and math field because it is based on students' achievements in middle schools; Second, the new selection system should consider the character and attitude of the applicants in addition to their knowledge; Third, the continuous observation of the teacher in middle school should be an important factor of the picking up system; Fourth, more questions requiring divergent thinking ability and inquiry skill should be developed as selective examination question. Also examination questions should cover the various contents from mathematics to science, and do not affect pre-learning; Finally, the system of present letting all students stand in one line should be changed into that of letting students in various lines. We can consider using multi-step selection system.

Objectives : The present study was performed to reveal differences between female and male cases of alopecia in their alopecia related variables such as patterns of hair loss, psychiatric characteristics, associate illnesses, and methods of treatment, and to use them as basic materials for proper management and early prevention of the alopecia prone cases. Methods : In order to analysis the gender difference in hair losses, the subjects were divided into two subgroups as the 51 cases of female alopecia and the 42 cases of male alopecia, who had visited to the department of psychiatry consulted from the department of dermatology, Yongsan hopital, ChungAng University, Seoul, Korea, from January 1998 to December 1998. In data analysis, the subjects were statistically assesed by chi-squre test and analysis of varaiance, through SPSS-$PC^+$ 9.0V. Results : 1) Female subjects were more likely showed lower socio-economical level including lower eonomical level, lower educational level, or lower occupational level in their parent's job, were more likely to have larger number of siblings and to have many sisters comparison to the male cases. 2) Female subjects were more likely visited to the department of dermatology, more history of alopecia in their female family members, lesser history of alopecia in their male family members, more loss of hairs in vertex or frontal region of scalp, lesser loss of hairs in occipital region, and lesser nail changes in comparison to the male cases. 3) Female subjects were more suffered from intra-familial conflicts and economical changes, or their introverted personality makeup, lesser likely suffered from changes of business and health changes, and showed lesser conflicts related with poorer adaptaion in their job life. 4) Female subjects were more likely diagnosed as depression or conversion disorders, more frequently complaint anxiety symptoms or depressive symptoms, higher level of anxiety index, lesser complaint somatization or obsessive compulsive symptoms, and lesser diagnosed as anxiety disorder in comparison to the male cases. 5) Female subjects were more likely tended to show personality makeup such as the introverted, the lie, the repressed, or the feminine trends than the male cases. 6) Female subjects were more significantly treated by antianxiety drug such as etizolam and dermatological therapies include tretinoin, and lesser treated by clotiazepam and prednicarbonate in comparison to the male cases. Conclusion : From the facts that The most important factors in developing hair loss in the female subjects in comparison to the male cases seems to be closely correlated with the serious psychopathology such as the presence of mental disorders including depression, the presence of complaining anxiety or depressive symptomatology, the presence of stressful life events such as intrafamilial life changes, and the presence of personality makeup such as the introverted, the lie, the repressed, or the feminine trends, the authors confirmed that dermatologists act as the primary care physician are in a unique position to recognize psychiatric comorbidity and execute meaningful intervention for female patients with the alopecia with psychiatrists.
