치주질환에 이환된 성인환자에서 상악전치의 치간공간과 아울러 정출이 발생된 경우 기능 및 심미의 회복을 위해서는 함입이동이 필요하다. 본 연구는 골하치주낭 즉, 수직적 골결손이 있는 절치의 함입이동시 치주조직 반응을 살펴보기 위하여 시행되었다. 상악 좌우 측절치에 골결손과 함께 치주질환을 유발시킨 성견 4마리를 실험대상으로 하여 양측 모두에 치주수술을 시행하고 결손부 최하방 치근면에 notch를 형성 한 2주후 우측 제2측절치는 4주간 함입이동 후 4주간 보정을 시행한 실험측으로, 좌측 제2측절치는 구강위생관리만 시행한 대조측으로 사용한 바 조직소견을 통하여 다음과 같은 결론을 얻었다. 1. 함입이동없이 치주수술만 시행한 대조측의 조직소견은 치주낭 깊이의 감소를 보였으나 notch 부위부터 치주낭 기저부까지 긴 접합상피 상태를 보였으며 신생백악질이 형성된 일부에서만 결합조직 부착의 양상이 보였다. 2. 함입이동을 시행한 실험측은 대조측에 비하여 상피부착이 줄어든 반면 보다 넓은 신생 결합조직 부착 소견을 나타내었다. 3. 대조측과는 달리 실험측 notch근처의 결합조직내에는 다수의 세포가 관찰되었으며, 신생 백악질 생성 역시 대조측보다 많이 관찰되었다. 이상의 결과는 치주질환으로 인하여 정출된 치아에서도 철저한 염증조절과 구강위생이 유지되고 적절한 크기의 힘에 의하여 순수한 함입이동이 적용된다면 바람직한 치료결과가 가능함을 시사하였다.

Using Zung's self-rating depression scale, the authors studied depression in 310 elderlies residing in the 9 home for the aged (HFA) in Kyungbuk area, and 234 elderlies living in Taegu city and 107 elderlies attending a Life-long education program in Taegu, which serve as a control group, Community resident elderlies(CRE). The research had been administered during the period from June to August, 1986. The results were as follows : 1. The mean scores of male. female. and the total of the elderlies in HFA were $38.95{\pm}11.55$, $44.18{\pm}14.15$:: and $42.8{\pm}13.7$ respectively while CRE marked $40.8{\pm}11.3$ for male, $45.2{\pm}12.0$ for female, and $43.4{\pm}11.9$ for the total. Therefore there were significant differences between male and female in both groups(p<0.01, p<0.001), though no significant difference between the two groups. However, the depression score of elderlies in HFA might be much higher than that of CRE if 81 elderlies(14.2%) in HFA who had been left out of the statistical evaluation due to their having severe depression, organic brain syndrom, or pseudoementia, etc had been included. 2. The score distribution by items for the elderlies in HFA were from highest scores hopelessness, worthlessness, emptiness, decreased appetite, confusion, while for CRE, hopelessness, decreased appetite, psychomotor retardation, indecisiveness, and worthlessness. Elderlies in HFA showed significantly high scores in depressed mood, weight loss, suicidal rumination(ideation) and psychomotor excitement, while CRE showed significantly high scores in decreased appetite, psychomotor retardation, indecisiveness, and dissatisfaction. 3. Elderlies who scored over 50 numbered 10 males(16%), 57 females(34%), and total of 67(29%) in HFA and 28 males(21%), 77 females(37%), and total of 105(31%) in CRE : female showed higher seores in both groups. 4. Psychosocial factors such as getting older(respectively p<0.01, p<0.01), being Buddhist(respectively p<0.01, p<0.01), and monthly pocket money less than \30,000(respectively p<0.001, p<0.001) were found to have a noticable impact on the depression level of the elderlies in both groups. Factors such as illiteracy (p<0.001, monthly pocket money less than \10,000(p<0.05), and having no family(p<0.01) recorded significantly higher scores among CRE than the elderlies in HFA.

The purpose of this study was to examine the health promoting behavior of university students and its related factors. A self-administered questionnaire survey was carried out for 1,031(male, 477, female, 554) students from 7 universities in Taegu from March 10 to April 15 2000. Collected data were analyzed by the $X^2$-test, t-test, ANOV A and structural equation modeling analysis. The results of this study were as follows; Mean score of health promoting behavior of women was higher than mean score of men(p〈0.01). According to the subordinate fields, female students showed significantly higher scores in the fields of stress management, nutrition, personal relations and alcohol-cigarette(p〈0.05). And in male students, the only fields of exercise had meaningfully higher score(p〈0.01). The highest degree of performance was marked in alcohol-cigarette field in female, and interpersonal field in male. In Both male and female students, the lowest field was health responsibility. The mean score of health promoting behavior showed significant differences in intermediating factors such as age, health education and grade in male, and such as grade, pocket money for a month, taking health education, perceived body shape and gastrointestinal symptoms in female(p〈0.05). The mean score of health promoting behavior showed significant differences in cognitive-perceptual factors and cues to action such as perceived health status, perceived benefits, perceived barriers, and health concern of parents in both male and female(p〈0.05). By the results of structural equation modeling analysis in male students, the economic status, gastrointestinal symptoms and perceived body shape as lean had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). In female students, perceived body shape as lean and perceived body shape as fat had significant direct effects on cognitive-perceptual factors($\mid$T$\mid$〉2.0). Grade, pocket money and health concern of parents had significant direct effects on health promotion behaviors($\mid$T$\mid$〉2.0). On the consideration of above findings, it is recommended that perceived health status and perceived benefits should be raised and perceived barriers should be lowered to increase health promoting behaviors, by means such as institutional approach which can enhance the primary prevention for a disease. In addition, the health policy for improving parents' concern about health as well as university students, through various ways such as health education, consulting, and health program, should be employed.

Due to the existence of asymmetry of information between doctor and patient, it has been believed that doctor might affect patient's decision making process of purchasing medical care. Based on this notion, doctor's reimbursement method has been suggested as an effective policy device of improving efficiency of patient's medical care use by way of its affecting doctor's practice pattern. By using the Community Tracking Study (CTS) household and physician data set, which includes not only various information on patient's medical care use, but doctor's practice arrangements and sources of practice revenue, this paper investigates the effect of community doctor's characteristics of reimbursement method on community patient's medical care use under the control of patient's socio-demographic characteristics and community doctor's practice type. In the process of estimating econometric model, the endogeneity problem of individual health insurance purchase was corrected by using 2818. And due to the existence of sample selection problem, Heckman's two-step estimation method was used for strengthen the robustness of estimation which was adversely affected by sample selection problem The empirical results show that as the average value of community doctor's portion of practice revenue determined by prospective method out of total revenue increases, the community patient's total out-of-pocket medical cost decreases. This results suggest, as doctor's practice revenues are mainly determined by prospective method, such as capitation, doctors would be more conscious about practice cost, which might affect doctor's practice pattern and by which his/her patient's use of medical care would decrease.

Graduate School of Public Health, Seoul National University The national health insurance system in Korea is characterized as relatively high out-of-pocket payments, which are the principal source of catastrophic health expenditure (CHE). The objectives of this study are to estimate the incidence of household CHE and to clarify the characteristics that affect the occurrence and recurrence of household CHE using the Seoul Welfare Panel Survey database for 2008 and 2010. Thresholds to estimate CHE were 10% and 20% of the total household income (T/X), and 25% and 40% of the income excluding food share (T/Y). Determinants of the occurrence and recurrence of CHE at the threshold of T/X=10% were analysed using multiple logistic regression models. Out of the 3,665 households that responded in 2008 survey, households with CHE were 12.07% (T/X${\geq}$10%), 5.34% (T/X${\geq}$20%), 6.84% (T/Y${\geq}$25%), and 4.44% (T/Y${\geq}$40%). Risk factors associated with household CHE included living with a spouse, non-Medicaid beneficiary, householder unemployment, low household income, the number of disabled members, poor subjective health, and the number of chronic diseases. A total of 41.78% of households with CHE in 2008 repeatedly experienced CHE in 2010. Risk factors of CHE recurrence included decreased household income and an increase in chronic diseases over the two time periods, the number of members with disability or chronic diseases, and the presence of cancer patients in 2008. Households with lower socioeconomic and health status had a higher financial burden on health care than do their counterpart households. There is a need to enhance society-wide financial protection from health spending among vulnerable citizens in Seoul, particularly, households with low income, disabled members or cancer patients.
