The purpose of this study was to investigate the effect of zinc intake on immune responses in high fat diet induced obese rats. The immune status was assessed by the measurements of immunoglobulins (IgG, A, and M) production by SRBC(sheep red blood cell) with mitogen in vivo. The delayed type hypersensitivity(DTH) response was also measured as an index of cell mediated immunity. The re sults are summarized as follows : 1) There were no significant differences in the feed intake, weight gain and feed efficiency ratio of obese rats by the different dietary zinc levels. 2) White blood cell (WBC) counts were significantly affected as the dietary zinc levels decreased. The capacity of Ig M production in obese rats was significantly higher in normal zinc group than that of low and high zinc group. Cell mediated immune response evaluated by means of DTH testing has also been found to be highly impaired by zinc deficiency and overload. From these observations, it was suggested that adequate levels of zinc may promote the immune function of obese individuals. The relationship and its functional role of the zinc in obesity remains to be further studied.

The purpose of this study is to describe the acknowledgement of the cause of the illness in the patients with RA. I used naturalistic inquiry as a research methodology. The purposive sampling was conducted. 23 subjects who experienced RA, lived in middle-sized city in Korea, and 19 women and 4 men. I collected data using indepth structured interview, "What is the acknowledgement of the cause of the illness?" I used inductive data analysis-such as unitizing and categorizing. This process is used constant comparative method. Summerising the results of this study, the acknowledgement of the cause of the illness are composed of physical constitution, fatalism, the attribution of physical overload, the attribution of stress, the lack of nutrition. The factors which affect the acknowledgement of the cause of the illness are composed of internal factors, external factors, environmental factors. The internal factors are the weakness of the childhood, the illness experience in the family members, juvenile rheumatoid arthritis, personality, lack of nutrition. The external factors are pregnancy, delivery, role burden and conflict, economic problem. The environmental factors are humid condition, abrupt environmental change. It is needed to explaine the coping pattern according to the acknowledgement of the cause of the illness in the next research.

본 연구는 미국의 치매노인 부양자들을 대상으로 하여 치매환자가 배우자인 경우와 부모인 경우를 분리하여 이들 두 집단의 우울증이 어떠한 차이를 보이는지 또 우울증에 영향을 미치는 요소가 어떻게 다른지를 회귀모형을 통해 분석해보았다. 분석결과에 의하면, 치매에 걸린 남편을 돌보는 아내 부양자가 치매에 걸린 부모를 돌보는 딸 부양자보다 우울증 점수가 더 높은 경향성을 보여주었다. 한편, 배우자 부양자와 딸 부양자 집단의 우울증 점수에 영향을 미치는 요소들에 어떠한 공통점과 차이점을 갖고 있는지 알아보기 위해 각각의 회귀분석을 실시한 결과는 다음과 같다. 먼저, 딸 부양자의 경우 역할부담감, 역할구속감, 그리고 문제행동이 그들의 우울증에 유의미한 영향을 주었고, 아내 부양자의 경우에는 역할부담감, 역할구속감, 문제행동, 그리고 교육수준이 우울증에 유의미한 영향을 주는 변수였으며, 마지막으로 남편 부양자에게는 오직 역할구속감과 문제행동만이 그들의 우울감에 유의미한 영향을 미치는 변수로 나타났다. 따라서 모든 부양자 집단의 우울증에 공통적으로 영향을 주는 유의미한 예측변수는 역할구속감과 문제행동이었다. 즉 부양자의 역할구속감이 클수록, 그리고 피부양자인 치매환자의 문제행동 수준이 높아질수록 부양자의 우울증 점수는 높아지는 경향성을 보였다.

Background: In Japan, more than 60% of employees are reported to suffer from anxiety and stress. Consequently, Japanese society has begun to address such important issues as psychogenic disability and job-related suicide. Furthermore, given the aging of society and the surge in the number of elderly people requiring care, it is necessary to adequately and proactively support employees who care for their elderly relatives. The purpose of the present study was to investigate caregiver burden in caring for elderly relatives and work-related stress factors associated with mental health among employees. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine mental health status. Results: The proportion of participants with a high K10 score was 15% (n = 106). Having little conversation with their supervisor and/or coworkers significantly increased the risk of depression [odds ratio (OR) 1.8], as did high job overload (OR 2.7) and job dissatisfaction (OR 3.8), compared with employees who frequently conversed with their supervisor and/or coworkers. Caring for elderly relatives as a prominent characteristic of an employee was a significant risk factor for depression (OR 2.1). Conclusion: The present study demonstrated that employees who were caring for elderly relatives were significantly associated with an increased risk of depression. To prevent depressive disorders, it may be important to focus on reducing the work-caregiving role conflict, as well as enhancing employees' job control and better rewarding their efforts in the workplace.

Objective: The purpose of this study was to investigate the effects of 5 different personalities on job stress in physical therapists. Design: Descriptive cross-sectional study. Methods: Structured self-report questionnaires consisted of demographic items, 5 types of personalities, and occupational stress. A questionnaire was distributed to 420 physical therapists working in Seoul and Incheon who had voluntarily agreed to participate in the study after the purpose of the study was explained. Of the 420 questionnaires, 405 questionnaires were collected and showed a recovery rate of 96.4%, of which 28 cases were excluded, leaving a total of 377 questionnaires being used for analyses. Pearson correlation analysis was performed to investigate the correlation of job stress and five personalities types. In addition, multiple regression analysis was performed to investigate the effect of general and occupational characteristics of physical therapist on job stress and the effect of personality type on occupational stress. All statistical significance levels were set at p<0.05. Results: The highest number of subjects, which were the physical therapists, showed the tendency to have a sincere personality, followed by affinity, openness, extroversion, and neuroticism. Physical therapists reported to be the most stressed in the order of professional role conflict, overload of work, work relation with a physician and supervisor, interpersonal relationship with patient and caregiver. The higher the level of affinity and sincerity, the lower the amount of stress received by the therapist from the interpersonal relationships between the patient and caregivers. On the other hand, the greater the level of openness and sincerity, the lower the stress levels related to professional role conflict. Conclusions: This study showed that the personality type and job stress of physiotherapists had a statistically significant effect. It is very important for physiotherapists to find their own way of coping with stress, which is satisfactory and appropriate for their job, because it is related not only to individual problems but also to the quality of patient care and medical services. Therefore, it is necessary to continue conducting research on how to relieve the stress levels of physical therapists according to their personality characteristics.

This study was intended to enhance the level of hospital personnel management through analysing job satisfaction of hospital employees in terms of structural, personal and environmental variables. The sample of this study consist of a total of 790 persons including doctors, residents, interns, pharmacists, nurses, medical engineers, office workers and manual workers who have worked for general hospitals with 200 beds, 300 beds and 800 beds respectively. The Likert's 5 scales were used for the measurement of satisfaction. The results can be summarized as follows: 1. Structural Variables The level of satisfaction on the job itself was generally low, 2.8 in Likert's 5 scales, with the order of role ambiguity(3.87), routinization(2.6), work overload (2.45) and autonomy(2.37). Hospital employees are aware of their responsibility and they regarded their work as heavy one. The compensatory satisfaction degree was 2.5 which was also low: There were in the order stability(3.1), distributive justice(2.57), pay(2.3) and promotion(1.9). Usually hospital employees showed high degree of stability, while, their satisfaction on promotion possibility is quite low due to specially differentiated structures of hospitals. The degree of satisfaction on the internal conditions of organizational culture was relatively higher as 2.92: They were co-worker's support(3.69), supervisory support(3.15), role conflict(2.64) and welfare(2.17) in order. The satisfaction on welfare as an economic condition was the lowest. 2. Personal Variables The level of satisfaction on personal variables was 3.27 which seemed to be quite high: Contribution to the hospital(3.38), attitude on job performance(3.28) and pride as a member of the hospital(3.07). They seem to believe that their work has been helpful to the performance of hospitals. 3. Environmental Variables The degree of satisfaction on these variables was 3.07 on the average which was derived from environmental factors such as family-role conflict and community support related to hospital employees' environment. The order of satisfaction for each variable is community support(3.2) and family-role conflict(2.94). They turned out to be fairly satisfied with their job in community and yet, they wanted more spare time to spend with their family.

The effect of melatonin on juveniles with cardio fibrosis is poorly understood. We investigated whether HDACs participate in the anti-fibrotic processes regulated by melatonin during hypertrophic remodeling. Abdominal aortic constriction (AAC) was employed in juvenile rats resulting in pressure overload-induced ventricular hypertrophy and melatonin was subsequently decreased via continuous light exposure for 5 weeks after surgery. AAC rats displayed an increased cross-sectional area of myocardial fibers and significantly elevated collagen deposition compared to sham-operated rats, as measured by HE and Masson Trichrome staining. Continuous light exposure following surgery exacerbated the increase in the cross-sectional area of myocardial fibers. The expression of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 genes were all significantly enhanced in AAC rats with light exposure relative to the other rats. Moreover, the protein level of $TNF-{\alpha}$ was also upregulated in the AAC light exposure groups when compared with the sham. However, Smad4 protein expression was unchanged in the juveniles' hearts. In contrast, beginning 5 weeks after the operation, the AAC rats were treated with melatonin (10 mg/kg, intraperitoneal injection every evening) or vehicle 4 weeks, and sham rats were given vehicle. The changes in the histological measures of cardio fibrosis and the gene expressions of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 were attenuated by melatonin administration. The results reveal that melatonin plays a role in the development of cardio fibrosis and the expression of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 in cardiomyocytes.

This study was conducted to determine whether follow-up management is carried out continuously following CQI activity and to analyze the factors behind the success and failure of follow-up management. Past presentations from 1994-1999 of CQI coordinators and lecturers from various institutions who presented at The Korean Society of Quality Assurance in Health Care(KoSQA) on the conditions of follow-up management in each institution were analyzed. The results of this study were as follows; Since the number of subjects on CQI increased each year at symposiums, this has expanded to all medical institutions. Although medical institutions usually conduct 11-20 subjects on CQI per year, there were many such occasions where more than 31 subjects were conducted. Moreover, institutions with less than 800 beds have come up with more projects than those with more than 800 beds, thus 23.3% of these institutions had at least 1 person involved in 4 projects. This had created an overload of responsibilities for specific persons' involvement, prompting them to incline toward formalities in their work rather than substantial activities. Among the projects presented at the symposiums, 51.7% demonstrated that follow-up management could be carried out. In particular, 55.3% of the projects from provincial regions could carry out follow-up management compared to 48.8% in Seoul. Moreover, it was demonstrated that 80% of the projects from institutions with 600-799 beds carried out follow-up management most effectively. With regards to previous presentations, the older they were, it was found that follow-up management could not be effectively carried out. Some institutions that responded that follow-up management was carried out effectively in their institutions were found to have conducted follow-up management without any inspection strategies or the appropriate tools. CQI activities were executed and terminated with no consistency and team members had no real concern for it. The most important factors that contribute to an effective follow-up management are the need for concern and interest from the directors of the hospitals, from the relevant departments and team members in addition to the role of the supervising department, follow-up management through management of target goals, consistency in tasks along with communication between all team members. The biggest problems were perceived to be overload of work due to accumulation of proposed projects in addition to lack of awareness pertaining to follow-up management. CQI is beneficial for all staff for the improvement of the mind and business administration and thus it is believed to be desirable. To carry out follow-up management effectively, leadership, analysis and application of information, follow-up management and planning, as well as quality management are perceived to be essential, on the other hand, the results showed a significant difference. To prevent CQI activities from becoming just an activity, the basic system should be reconstructed and augmented based on the problems derived from the results of this study. Moreover, we hope this study will be used as reference material that would encourage the administration of follow-up management after CQI activities in most hospitals. Furthermore, various studies on follow-up management should be conducted for CQI activities in the future.
