The purpose of this study is to help the care of patient and to his family through comparison of the level of anxiety which between the family of admitted patient and the family without in patient, and to his family through comparison of the level of anxiety which between the family of admitted patient and the family without inpatient and exclude the factors which raised the level of anxiety in them. The experimental group in this study were samples of 200 patient's family selected by random sampling in H. University hospital located in Seoul (Department of patient were internal medicine, surgery, pediatrics and neuropsychiatry). The control group were samples of 70 family without inpatient selected by random sampling in Seoul. The data were collected through STAI (State-Trait Anxiety Inventory) by Spielberger (1970) for measurement to level of state and trait anxiety from April 1st to April 15th in 1982. The contents of data analysis by EDPS included the difference of level of anxiety between experimental and control group, correlationship between general characteristics of experimental group and level of anxiety, and correlation of trait and state anxiety in experimental group. The Findings of this study were as follows: 1) Level of anxiety of experimental group is higher than control group. 2) In the correlation between general characteristics and level of anxiety of experimental group, there were no significant difference which revealed in correlation with age of family member, family life cycle, marital status, the relation between patient and family member, the degree of symptom, number of admission, admission or nonadmission of medical insurance, number of family member, and division of disease to level of anxiety However, according to the sex of family member, hospitalization period, a monthly income of family, the degree of confidence toward medical team, religion of family, academic background of family, a tendency of significant differences to level of anxiety were seen. To put them in the concrete, they were as follow; a) Level of. anxiety on female family member is higher than male in experimental group. b) Admission period of patient is positively related to the level of anxiety of patient's family. c) The degree of confidence of patient's family toward medical team is in inverse proportion to the level of anxiety. d) A monthly income of patient's family is in inverse proportion to the level of anxiety. e) Levlt of anxiety of believer in patient's family is lower than unbeliever. f) The academical background of patient's family is in inverse proportion to the level of anxiety g) Level of state anxiety of patient's family at the time of admission is positively related to the level of trait anxiety.

Although the rate of women farmer's participation in agricultural activities have been increased upto 52.7 % as of year 2003, Korean society has not fully recognized their roles in rural society. According to the agricultural basic law, most of rural women were engaged in agriculture as full time job, however, only about 11% of them could have supporting evidence of themselves as farmer having legal right. If women farmers faced some unexpected things such as a traffic accident, insurance company would not reward them as farmers unless they provide written proof of their job as farm worker or farm owner. Based on lawyer's legal advice, the authors developed a diary called "Saenghwalilji", a daily diary based on their time use and bookkeeping to prove the fact of their contribution to income generation of the farm. After examination of the diary, 18 persons out of 29 volunteers kept two types of dairy for the period of two weeks, and they reported it was very useful. Finally the better one of two was selected after reflecting the suggestions from the respondents. The "Saenghwalilji", will be very useful proof of women farmer's contribution to income, at the same time improving their farm management through better use of daily life time.

Objectives: To investigate the patterns of unintentional home injuries in Korea. Methods: The study population was 12,382,088 people who utilized National Health Insurance services due to injuries (main diagnosis codes S00 to T28) during 2006. Stratified samples(n=459,501) were randomly selected by sex, age group and severity of injury. A questionnaire was developed based on the International Classification of External Causes of Injury and 18,000 cases surveyed by telephone were analyzed after being projected into population proportionately according to the response rates of their strata. Domestic injury cases were finally included. Results: Domestic injuries (n=3,804) comprised 21.1% of total daily life injuries during 2006. Women were vulnerable to home injuries, with the elderly and those of lower income (medical-aid users) tending to suffer more severe injuries. Injury occurred most often due to a slipping fall (33.9%), overexertion (15.3%), falling (9.5%) and stumbling (9.4%), with severe injury most often resulting from slipping falls, falls and stumbles. Increasing age correlated with domestic injury-related disability. Conclusions: The present findings provide basic information for development of home injury prevention strategies, with focus on the elderly.

The aging process in this country is underway at the fastest pace compared to those of the leading countries. On the other hand, preparing for retirement funds is more difficult than before due to the impact of slow interest rate and slow growth. The purpose of this study is to examine the necessity of providing various financial services in preparation for the future aging era. After analizing the various materials and utilizing a survey of the bank employees and the general public, we have found the followings. The replacement rate of this country, 55%, is much lower than the suggested level of World Bank, 75%. Also, the pension ratio in the income after retirement of this country is much lower compared to those of the States and Japan. The most people who participated in the survey needed ￦2,000 - ￦2,990 thousand for monthly living expenses after retirement. For the retirement funds, the higher the age the higher proportion of savings deposits they want, and the lower the age the higher proportion of insurance and pension products they want. Based on these analyses, the necessities of developing financial life planning which includes both financial and non-financial sides, retirement funds management according to age, revitalization of housing pension and developing diverse retirement funds are suggested.

Objective : Questionnaires completed by occupational therapists and patients in institutions conducting a "Pilot Project of Rehabilitation Medical Institutions" were used to determine whether occupational therapy was able to establish appropriate patient support systems for return to home and community. Methods : The questionnaire was completed by 293 occupational therapists from 13 institutions conducting pilot projects and 296 patients from 8 institutions who were able to respond. Results : Although the Pilot Project of Rehabilitation Medical Institutions is being implemented to enable early return of patients to activities of daily living, the most important therapeutic goal is not efficiently applied. In addition, since the health insurance systems utilized in medical institutions are applied as in the pilot project, there is no basis for evaluation and mediation of practical daily activities and vocational rehabilitation for actual return to the community. Conclusion : Through a detailed review of the pilot project, it will be necessary to improve the quality of life through the early return of patients to social activity, and to make practical improvements to reduce unnecessary societal expenditures.

Cataract is the main cause of blindness and visual impairment, especially, age-related cataract accounts for about half of the 32 million cases of blindness worldwide. As the life expectancy and the expansion of the elderly population are increasing, the cases of cataract increase as well, which causes a serious economic and social problem throughout the country. However, the incidence of cataract can be reduced dramatically through early diagnosis and prevention. In this study, we developed a prediction model of cataracts for early diagnosis using hospital data of 3,237 subjects who received the screening test first and then later visited medical center for cataract check-ups cataract between 1994 and 2005. To develop the prediction model, we used random forests and compared the predictive performance of this model with other common discriminant models such as logistic regression, discriminant model, decision tree, naive Bayes, and two popular ensemble model, bagging and arcing. The accuracy of random forests was 67.16%, sensitivity was 72.28%, and main factors included in this model were age, diabetes, WBC, platelet, triglyceride, BMI and so on. The results showed that it could predict about 70% of cataract existence by screening test without any information from direct eye examination by ophthalmologist. We expect that our model may contribute to diagnose cataract and help preventing cataract in early stages.

Software reliability factor during the software development process is elementary. Case of the infinite failure NHPP for identifying software failure, the occurrence rates per fault (hazard function) have the characteristic point that is constant, increases and decreases. In this paper, we propose a reliability model using the chi - square distribution which depends on the degree of freedom that represents the application efficiency of software reliability. Algorithm to estimate the parameters used to the maximum likelihood estimator and bisection method, a model selection based on the mean square error (MSE) and coefficient of determination($R^2$), for the sake of the efficient model, were employed. For the reliability model using the proposed degree of freedom of the chi - square distribution, the failure analysis using the actual failure interval data was applied. Fault data analysis is compared with the intensity function using the degree of freedom of the chi - square distribution. For the insurance about the reliability of a data, the Laplace trend test was employed. In this study, the chi-square distribution model depends on the degree of freedom, is also efficient about reliability because have the coefficient of determination is 90% or more, in the ground of the basic model, can used as a applied model. From this paper, the software development designer must be applied life distribution by the applied basic knowledge of the software to confirm failure modes which may be applied.

The effects of job related factors on psychosocial health status were examined by taking job stress into account. The self-administered questionnaires were performed, during the period between Oct. 1st, 2009 and Nov. 30th, 2009, to 805 individuals in the service of general administration located in Daejeon City. Causal relationships between job related factors, job stress, and, psychosocial health status were examined by structural equation model. The main finding as follows: For correlations of such indices of psychosocial health status as PWI and MFS with various studied items, all of these two indices were found to be in a negative correlation with the job position, job career, satisfaction in job life, autonomy of job, supervisors support and coworkers support, whereas in positive correlation with the experience of sick absence per year and job demand. With the analysis of structural equation model, the degree of job stress factors was more influential on the level of psychosocial health status than job related factors in such a manner as that the greater the job stress, while the lower the job related factors, the higher the psychosocial health status(PWI and MFS). Moreover, it was found to have the inter-relational effects that the greater the job related factors, the lower the job stress factors. Thus the effective strategy for stress and fatigue symptoms reduction among governmental employees requires additional programs focusing on innovated job specifications.

As people are easy to access the National Health Insurance, medical health service has been increased. It contributed to extend human's average life expectancy and to get better health care. But also increased unnecessary health service or inappropriate drug use. Therefore, DUR (Drug Use Review) is needed to induce appropriate drug use. The purpose of this study is to evaluate outpatient prescriptions by General Practitioner (GP) and Specialized Practitioner, especially indication for ENT referral including common cold which is the frequent indications that have patient see doctor. This study was reviewed retrospectively prescriptions for ENT referral collected at the A pharmacy for ENT Clinic in Cheong-Ju, B pharmacy for GP Clinic in BoEun from Feb 2nd, 2009 to Feb 28th, 2009. Each pharmacy located closed to the each enrolled clinic. The numbers of collected prescriptions were each A pharmacy (n=2501), B pharmacy (n=1343). This study was classified Drug Related Problems (DRPs) those prescriptions had as total 6 groups according to following 6 categories; 1) Unnecessary Drug, 2) Wrong Drug, 3) Low Dose, 4) Overdose, 5) Wrong Instruction, 6) Wrong Combination. In results, Specialized Practitioner's prescriptions had more DRPs than General Practitioner's prescriptions (ENT 155.34% vs GP 130.01%). In detail, Specialized Practitioner's prescriptions had more DRPs in Low Dose (ENT 16.95% vs GP 4.77%), Overdose (ENT 6.72% vs G.P 5.51%), Wrong Instruction (ENT 7.91% vs GP 5.81%), Wrong Combination (ENT 29.31% vs GP 25.09%). These DRPs would be caused from lack of consideration for dosage and drug interaction. General Practitioner's prescriptions had more DRPs in Unnecessary Drug (ENT 70.37% vs GP 78.85%), Wrong drug (ENT 4.12% vs GP 9.98%). These DRPs would be associated with drug selection. This study was assumed that Specialized Practitioner is better prescriber than General Practitioner because Specialized Practitioner complete additional intern and residency training. But, Specialized Practitioner is not always better prescriber than General Practitioner. Furthermore, prescriptions of both Specialized Practitioner and General Practitioner had many problems. In conclusion, It could be cut down the excessive medical expense and expected more efficient medical care by reducing DRPs, thus contributing to the improvement of national health. In order to pharmacist must have good professional ability of pharmacotherapy to help the physician for the drug selection.

The study found out developmental factors of the liver diseases in 29, 531 cases of the healthy adults who were diagnosed by using ultrasound at domestic healthcare centers in 6 cities. The results are as follows. Based on the result of the study, the liver diseases diagnosed by using ultrasound was revealed to show 43.1% of prevalence, and the occurrence was significantly higher in male (23.3%) than in female (19.8%). The prevalence of hepatic diseases related to the BMI was revealed to show highest prevalence of the fatty liver in obese group (BMI $\geqq$ 25) by recording 44.3%. Smoking contributed to the high prevalence of all liver diseases. Although the fatty liver was the most frequently occurred form of liver diseases by recording the prevalence of 49.1% (22.2% in male, 26.9% in female), the significant difference was found only in female (p < 0.05), but male group did not show significant difference (p > 0.05). The prevalence of hepatic diseases related to the hypertension was revealed to show highest prevalence of the fatty liver in hypertension group by recording 67.7%. The prevalence of hepatic diseases related to the diabetes was revealed to show highest prevalence of the fatty liver in diabetes group by recording 66.2%. The high prevalence of all hepatic diseases was related to diabetes mellitus with statistical significance (p < 0.001). The multiple regression analysis for the related factors which affect the prevalence of the liver diseases showed the higher prevalence by age. Sex, obesity and diabetes mellitus were positively related to the prevalence (p < 0.05) while hypertension and smoking showed no significant relationship to the prevalence of the disease (p > 0.05).
