This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

진행 위암환자에서 Lymphokine-Activated Killer (LAK) 활성의 저하

홍원선,김영환,송재관,강윤구,이진오,강태웅,김정룡 대한내과학회 1990 대한내과학회지 Vol.38 No.3

Natural killer(NK) and lymphokine-activated killer(LAK) activities were determined in 31 patients with unresectable stomach cancer before and immediately after chemotherapy with 5-fluorouracil, adriamycin and mitomycin C(FAM) and 31 healthy volunteers. The major purposes of the study were focused on whether peripheral blood lymphocytes(PBL) in stomach cancer patients had a similar ability in the generation of LAK activity to those in healthy volunteers and what the effect was of chemotherapy with FAM on the generation of LAK activity. LAK cells were generated in vitro by culturing human PBL with 100 U/㎖ of recombinant human interleukin-2(rH-IL-2) for 72 hours. K562(human myelogenous leukemia cell line) and MKN-45(human stomach adenocarcinoma cell line) were used as target cells for NK and LAK activities. NK activity against K562, a sensitive line, was significantly depressed in patients with stomach cancer compared with that in healthy volunteers(p<0.01). However, LAK activity against K562 was similar to that of the controls. Age, sex and performance status(ECOG 0-2 and 3-4) did not have an influence on both NK and LAK activities. LAK activity was significantly higher than NK activity, either against K562 or MKN-45, in both healthy volunteers and patients with stomach cancer(p<0.001). NK and LAK activities against MKN-45, a NK-resistant line, in patients with stomach cancer showed significantly lower levels than those in healthy volunteers. We also analyzed the effect of chemotherapy with FAM on NK and LAK activities, with no suppression of NK and LAK activities being observed. In this study, we have demonstrated that PBL of stomach cancer have a reduced ability to generate LAK activity in response to rH-IL-2. However, LAK activity generated from PBL receiving chemotherapy with FAM was similar to that of PBL without chemotherapy.

認知治療에 關한 理論的 考察

宋在鴻 全北大學校 學生生活硏究所 1993 學生生活硏究 Vol.20 No.-

Cognitive therapy(CT) or cognitive-behavioral therapy(CBT) is a relatively short-term form of psychotherapy that is active, directive, and collaborative between patient and therapist. The basic premise of the cognitive therapy model is that there is an essential interaction between the way in which individuals feel and behave and the way in which they construe their world, themselves, and the prospects for their future. The goal of therapy is to help patients uncover their dysfunctional and irrational thinking, reality-test their thinking and behavior, and build more adaptive and functional techniques for responding both inter- and intra-personally. The goal of this review is to offer the reader an overview of the basic cognitive therapy model, with specific focus on understanding the broad cognitive-therapy perspective. For this purpose, this researcher examined the historical background of cognitive therapy, described the main conceptions(e.g., cognitive triad, cognitive distortions, dysfunctional or irrational assumptions, schema, etc.), therapeutic precesses, and (both cognitive and behavioral) strategies and techniques, with which cognitive therapists had established their therapeutic models and had developed their clinical pratices, and finally added the evaluation of cogitive therapy model, with specific focus on improving its future.

질소오염 감소를 위한 질소수지표 개발에 관한 연구 : 충청북도 사례연구 For Province Chungcheongbuk-do

These days, the environment has been polluted as a result of many kinds of agricultural activities, such as over-fertilization and excessively injected agricultural medicine and livestock-wastewater. Especially, superfluously used nitrogenous fertilizers have worsened both ground water and earths surface water. In Korea, compared to other developed countries, there has been an extensive use of nitrogenous fertilizer, affecting the cleanliness of ground water. Under these circumstances, it is imperative to study the pollution by nitrogenous fertilizer. In order to estimate the extent of potential pollution by nitrogenous fertilizer, this study establishes a nitrogen parameter by providing the balance between the inputted quantity of nitrogen element (marked as plus) and the output quantity of nitrogen element (marked as minus). For the calculation of surface nitrogen balance, nitrogen input was calculated by fertilizer consumption and cattle manure input etc., and nitrogen output was mainly harvested crop products. This balance, by indicating the extent of potential pollution, may be used to improve the effectiveness of environment policy making. In Province Chungcheongbuk-do(Chungbuk), a surplus of nitrogen is 15.3kg/10a. However, each region has different levels of surplus based on the amounts of nitrogenous fertilizer used, soil and climate. We observe that the policy to reduce pollution by nitrogen must be applied based on environmental characteristics of each region. In conclusion, the nitrogen parameter has significance in planning environmental policy that is appropriate to each region, by helping to analyze the effect on rural household income and to solve other environment-related problems.

With rapid growth of the internet, need for the mobile communication networks is increasing. In this paper, we implement and test Mobile IP Protocol in Embedded System. Our Mobile IP-based testbed consisted of two sub-networks and each sub-network was configured to operate independently through use of router. To satisfy integrated wired/wireless network model established on the testbed design and show generality of the testbed, we implemented mobile nodes, home agent, foreign agent and router on the basis of Linux operating system. As the results of the evaluation, we confirmed that mobile nodes operated properly according to Mobile IP Protocol.
