노인기의 가장 빈번한 신경정신 질환의 하나인 우울장애의 유병율과 관련 요인을 알아보기 위해 제주도 농촌지역의 65세 이상 노인 590명을 대상으로 축약형 노인우울척도와 설문지를 사용하여 조사했다. 확정적 인지장애 노인을 배제한 집단에서 우울증상 점수는 연령에 따라 증가하는 경향을 보였으며, 성별의 차이는 없었으나 80세 이후의 남자에서 특히 우울점수가 높았다. 우울점수가 10점 이상인 의미있는 우울증상의 유병율은 16.6%(남자 14.2%, 여자 17.8%)이며, 성별의 차이는 없었다, 우울증상의 발병 위험도를 높일 것으로 추정되는 의미 있는 인자는 낮은 경제상태, 만성 신체질환의 이환, 나쁘게 자각된 건강상태이며, 거동의 불편도 영향을 줄 수 있는 것으로 추정되었다 Objective:Depressive disorder is one of the most frequent and serious neuropsychiatric disorders in the elderly. This study is aimed to investigate the prevalence and related factors of depressive symptoms among the elderly in rural areas of Jeju island. Methods:The Short form of Geriatric Depression Scale (SGDS) and structured questionnaire about factors related with depression were administered to 590 rural-dwelling elderly in Jeju island. Results:The overall prevalence of depressive symptoms over score 10 in SGDS is 16.6% (Male 14.2%, Female 17.8%). But there was no sex difference. And statistically significant factors related with depression by multiple logistic regression analysis were economic status, chronic physical illness, and self-perceived health status. Factor of physical limitations would be a possible associated one. Conclusions:The prevalence of depressive symptoms of Jeju island was nearly same as that of other areas. And several risk factors for depression were identified but further evaluation will be needed because of those complex and controversial findings.

This study is performed to develop an educational authoring package which helps teachers produce English vocabulary learning materials with ease. For this purpose an authoring package "Wordbank" is designed in relation to English conversation class. The authoring package, "Wordbank" provides teachers with convenient way to produce vocabulary learning materials and also provides students with a chance to practice and evaluate the vocabularies dealt in classrooms. "Wordbank" has a database with 3 kinds of vocabulary learning exercises. With this package teachers can input new vocabulary items and search for the wanted vocabulary items related to the text, and give a test with exercise sets. Students can search and practice vocabularies in the text not only for the preparation for the class but also for the review of the class. Considering that web-based programs in general have difficulty in providing materials related to the class lessons and editing the contents, "Wordbank" is expected to effectively provide more chances of vocabulary learning to students.

Objectives Non-major depression with fewer symptoms than required for a Diagnostic and Statistical Manual of Mental Disorders-4th edition diagnosis of major depressive disorder (MDD) has consistently been found to be associated with functional impairment. In this study, we aim to estimate the cognitive impairment and the quality of life in elderly patients with subsyndromal depression (SSD) compared with non-depressive elderly (NDE). Methods The Korean version of Mini International Neuropsychiatric Interview was administered to 194 outpatients with depression and 108 normal controls. SSD is defined as having five or more current depressive symptoms with core depressive symptoms (depressive mood or loss of interest or pleasure) during more than half a day and more than seven days over two weeks. Depression was evaluated by the Korean form of Geriatric Depression Scale of a 15-item short version. Global cognition was assessed by Mini-Mental State Examination in the Korean version of CERAD assessment packet (MMSE-KC). Subjective cognitive impairment was assessed by the Subjective Memory Complaint Questionnaire. Quality of life was evaluated by the Korean Version of Short-Form 36-Item Health Survey. Results The mean score of the MMSE-KC in the SSD group was lower than that in the NDE group with adjustment for age, gender, and education [F = 4.270, p = 0.04, analysis of covariance (ANCOVA)]. If we defined those having Z-score of MMSE-KC < -1.5 as a high risk group of cognitive impairment, the odds ratio for the high risk group of cognitive impairment was 1.86 [95% confidence intervals (CI) 1.04-3.34] in SSD and 7.57 (95% CI 3.50-16.40) in MDD compared to NDE. The scores of physical component summary (F = 9.274, p = 0.003, ANCOVA) and mental component summary (F = 53.166, p < 0.001, ANCOVA) in the SSD group were lower than those in the NDE group with adjustment for age, gender, and education. Conclusions The subjects with SSD, as well as those with MDD, showed impairment of global cognition and also experienced low quality of life in both physical and mental aspects, compared to the NDE group.

Objectives Restless legs syndrome (RLS) is a sleep disorder characterized by uncomfortable and unpleasant sensations in the legs and an urge to move the legs, usually at night. The aim of this study is to investigate the incidence of RLS in patients with late life depression and its influence on various clinical outcomes such as severity of depression, sleep quality, cognitive function, and quality of life and accordingly, to elucidate the clinical significance of RLS in patients with late life depression (LLD). Methods This study enlisted 170 depressive patients aged 65 years or older from an outpatient clinic. Structured diagnostic interviews were performed using the Korean version of the Mini-International Neuropsychiatric Interview. All patients completed the questionnaires, including the International RLS Severity Scale, the Korean version of Short-Form 36-Item Health Survey (SF-36), and the Pittsburgh Sleep Quality Index (PSQI). The severity of depression was evaluated by the Korean form of the Geriatric Depression Scale (KGDS) and the level of global cognition was assessed by the Mini-Mental State Examination in the Korean version of The Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (MMSE-KC). Results The incidence of RLS was 17.6% in LLD patients. RLS was more prevalent among the subjects with major depressive disorder (MDD) than those with minor depressive disorder or subsyndromal depressive disorder. The RLS group showed higher score in the KGDS than the Non-RLS group but the difference did not reach the statistical significance (p = 0.095, Student t-test). The mean PSQI score was significantly higher in the RLS group than in the Non-RLS group (p = 0.001, Student t-test). The MMSE-KC score was also lower in the RLS group than in Non-RLS group (p = 0.009, analysis of covariance). But, there was no difference in the score of SF-36 between the RLS group and the Non-RLS group. Conclusions RLS is common in LLD patients, especially in the patients with MDD and is associated with poor sleep quality and cognitive dysfunction, indicating that RLS is clinically significant in patients with LLD. Therefore, RLS should be considered as an important clinical issue in the management of LLD.

Financial ratio indicators of the 73 sample hospitals provided by the Korea Hospital Association in 1998-1999, together with the data by the Korea Health Industry Development Institute in 1997, were analysed to identify the financial structure and managerial performance of the profit/loss-making hospitals under the IMF. The major findings of this study were as belows. 1. Among the general characteristics, there was a statistical significance in the hospitals location and the number of operating beds between profit-making hospitals and loss-making hospitals. 2. Financial ratio indicators of the profit-making hospitals were better then those of the loss-making hospitals. 3. Financial ratio indicators, including Liquidity, Performana Indicators and Growth Rate Indicators of profit-making hospitals, were better than those of loss-making hospitals except for Turnover Ratios under the IMF economic impasse.

This study was designed to find out the relations between the major investment decision-making behaviors and profitability of the hospital. A total of 57 hospitals were analyzed on this study. The major findings were as follows ; 1. Among the types of the investment decision-making, major factors affecting the profitability were where the top management belongs among the defender, analyzer, prospector, and reactor type. Other factors were whether or not hospital analyzed which is more economical between the purchase by cash and lease of the medical equipment and whether or not hospital changes the decision before the actual investment. 2. Among the types of the investment decision-making, major factors affecting the financial structure and efficient operation of the assets were ranking of the priority and whether or not hospitals can get enough revenue and cash flow when hospitals have to borrow a big amount of fund from outside. 3. Among the financial indices regarding the financial stability, major factor affecting the profitability was fixed assets to long-term capital. Other factors affecting the financial structure and efficient operation of the assets were value added to medical equipment, normal profit to medical equipment, liability to total assets, current ratio, value added to payroll expenses. 4. Investment decision-making behaviors are partially influencing on the financial structure and efficient operation of the assets. However it was proved that the profitability was the most influencial factor than other factors related with the operation of the hospital. 5. To improve the irrational investment decision-making behaviors strategic management system should be introduced, and the top management`s investment decision-making style should be changed from reactor and analyser styles to prospector and reactor ones.
