Objectives : This study aims to identify factors affecting satisfaction among the elderly with complete denture to help the elderly with complete denture perform oral hygienic care and to contribute to improvement in oral health. Methods : Interviews were performed with 247 people having complete denture, who were over 65 years and resided in Daejeon and South Chungcheong Province, from March 5 to 31, 2009. Results : 1. As for satisfaction in areas of complete denture by the number of brushing, chewing, pronunciation, and aesthetic functions were all high in over three times of brushing, showing statistically significant differences in satisfaction with chewing (p=0.1825) and aesthetic (p=0.005) functions. 2. As for satisfaction in areas of complete denture by the period of using denture, chewing, pronunciation, and aesthetic functions were all high in less than 7 years, showing statistically significant differences in satisfaction with chewing (p=0.030) and aesthetic (p=0.000) functions. 3. As for satisfaction in areas of complete denture by the subjective oral health state, the better subjective oral health state, the higher satisfaction with chewing, pronunciation, and aesthetic functions, showing statistically significant differences (p=0.000). 4. As for relevance between the subjective oral health state and satisfaction with complete denture, there was 30.1% explanation power in satisfaction with complete denture by the subjective health state. Conclusions : As for satisfaction with complete denture among the elderly, more than three times of brushing and less than 7 years of using denture were related to higher satisfaction; the better subjective oral health state, the higher satisfaction with chewing, pronunciation, and aesthetic functions.

태양 전지판의 전개 여부는 저궤도 위성의 발사 성공 여부를 판단하는 가장 중요한 항목 중 하나이다. 태양 전지판이 성공적으로 전개되어야만 태양 지향 자세제어에 의해 위성 운용에 필요한 전력 생성이 가능하기 때문이다. 그러므로 발사 후 지상국 교신을 통해 최우선적으로 태양 전지판의 전개 여부를 판단한다. 태양 전지판의 전개 여부는 다양한 실패 상황에 가정해 총 5가지 조건을 통해 판단한다. 첫째, SAR1, SAR2의 입력 전류가 모두 0.8A보다 커야 한다. 만약 하나라도 0.8A 미만이라면 한 개 이상의 태양 전지판이 전개되지 않고 1번 태양 전지판이 태양 지향을 하지 못하는 상황이다. 둘째, SAR1 입력 전류와 SAR2 입력 전류의 값이 유사해야 한다. 만약 입력 전류 값이 크게 차이가 난다면 2번과 3번 태양 전지판 중 하나만 태양 지향을 하는 경우이다. 셋째, CSSA#5 출력 전류가 3.2mA보다 커야 한다. 만약 3.2mA보다 작다면 2번과 3번 태양 전지판의 전개가 실패하고 1번 태양 전지판이 태양 지향을 하는 경우 또는 1번 태양 전지판이 전개 실패하고 태양 지향을 하는 경우이다. 넷째, S/C Roll, Pitch, Yaw rate이 모두 0.2 deg/sec 보다 작아야 한다. 만약 body rate이 크다면 1번 태양 전지판의 전개 실패 상황을 예상할 수 있다. 다섯째, 각 태양 전지판의 온도 차이가 $35^{\circ}C$ 보다 작아야 한다. 만약 온도 차이가 크다면 1번 태양 전지판 전개 실패 상황에서 2번과 3번 태양 전지판이 태양 지향을 하는 경우이다. 총 다섯 가지의 조건을 모두 만족해야만 태양 전지판이 성공적으로 전개되었다고 판단한다. 태양 전지판의 전개 판단은 위성이 발사체에서 분리되고 약 4500초 이후 시점에 스발바드 지상국과의 교신을 통해 확인되었다. 이 시점의 SAR1 입력 전류는 약 2.00A, SAR2 입력 전류는 약 1.93A였기 때문에 모두 0.8A보다 크고 서로 유사한 값임을 확인했다. CSSA#5의 출력 전류는 약 3.5mA의 값을 나타냈다. S/C Roll rate은 -0.0084 deg/sec, Pitch rate은 -0.0072 deg/sec, Yaw rate은 -0.0303 deg/sec의 값을 나타냈다. 각 태양 전지판의 최대 온도 차이는 $7.7^{\circ}C$의 값을 나타냈다. 5가지 조건을 모두 만족함으로써 태양 전지판 전개는 성공적으로 수행된 것으로 판단했다.

In Korea, there are a total of 8 creative cities selected by UNESCO in 7 fields. UNESCO creative city refers to a network of creative cities with international level of experience, knowledge, and expertise in the field of culture and arts. Based on the PCSI 2.0 model, this study conducted a satisfaction survey of experts on Daegu's Creative City. Variables were composed of service quality, social responsibility, inconsistency, satisfaction and performance, and service quality was measured by dividing it into three categories: content quality, delivery quality, and environmental quality. Therefore, this study verified that the three types of quality, social responsibility, and inconsistency affect satisfaction, and that satisfaction affects performance. As a result of the study, it was found that the three service quality did not directly affect satisfaction, but rather affected satisfaction through inconsistency. So, 3 out of 10 hypotheses were rejected.

Objective: The aim of this study was to investigate variables which account for grandchild caregiving grandmothers' physical health satisfaction and leisure activity satisfaction. Methods: The sample included 141 grandmothers. Data were analyzed by descriptive statistics, Pearson's correlation, and hierarchical multiple regression. Results: Firstly, the variables that explained physical health satisfaction of grandchild caregiving grandmothers were educational level, family income, the number of grandchild, and caregiving conflict with adult child. When their educational level were higher, had more money, cared for grandchild more, and did not experience conflict with adult child, they showed the higher scores of physical health satisfaction. Secondly, as to leisure activity satisfaction of grandchild caregiving grandmothers, educational level and caregiving conflict with adult child were included. That is, they had higher educational level, and without caregiving conflict with adult child, grandchild caregiving grandmothers reported higher levels of leisure activity satisfaction. Conclusion/Implications: Based on these results, various implications and interventions were suggested.

우리나라 하구에 조성된 담수호의 수자원은 다양한 용수 목적에 맞게 활용하고 있으며, 수질 기준에 부합하는 용수를 공급하고 담수호 및 간척지의 친환경적 가치를 높이기 위해서는 담수호의 상류 유역 및 유입 오염물질, 그리고 담수호 수체 특성에 대한 종합적인 이해를 기반으로 수질 오염 관리 대책을 수립하는 것이 중요하다. 일반적으로 담수호 개선을 위한 방안의 선정 방식은 연평균 수질 농도를 기준으로 목표하고자 하는 수질 기준의 만족 여부에 대한 평가와 경제적 평가를 함께 고려하여 최적의사결정 기반으로 주로 이루어져 왔다. 그러나 기존의 평가 방법에서는 목표 수질의 만족 여부가 중요하다는 점에서 담수호 수자원의 시기별 활용성에 대한 고려를 간과하기 쉽다. 또한 담수호 수자원 시스템의 수질 악화에 대한 회복탄력성을 높이는 일은 단순히 유역관리대책의 적용에 따른 수질 개선 문제와는 별도로 담수호 수자원 시스템의 지속 가능성과 연관된다는 점에서 기존의 평가 방식을 보완하기 위한 수단이 필요하다고 할 수 있다. 따라서 본 연구에서는 담수호 수자원 관리 방안을 평가하는 데 있어서 회복탄력성의 개념을 활용하였으며, 각 방안에 대한 시간적 변화에 따른 담수호의 회복탄력성 특징을 고려하기 위하여 동적 회복탄력성 개념 및 평가 방법을 도입하였다. 본 연구에서는 우선 기존의 수질 평가 방법에 따라 간월호를 대상으로 수질 개선 방안별 수질 변화를 SWAT-EFDC 연계모형을 통해 모의하고, 연평균 수질 농도와 총인 삭감량에 대해 분석하였다. 분석 결과, 간월호의 지형학적 특성에 따라 간월호 상류 구간의 수질 농도가 다른 구간에 비해 높게 나타났으며, 상류 구역의 경우 준설 시나리오만으로는 목표 수질을 달성하기 어려운 것으로 나타났다. 따라서, 상류 구역의 수질 목표 달성을 위해서는 준설 시나리오만으로는 한계가 있으므로 상류 유역 출구부에 위치한 하수처리시설의 총인 배출부하량을 삭감과 추가적인 유역 수질 관리 대책이 필요하다.

The purpose of this study was to determine the degree of job satisfaction of school food service employees in the Daegu and Kyoungbuk area and to compare their job satisfaction among 3 types of school foodservice systems. Questionnaires were mailed to 49 elementary schools and collected from 49 dieticians and 201 employees. The survey form was developed by analyzing the Job Descriptive Index(JDI) with the five facets of a job: the work itself, promotion pay, supervision and colleagues. Statistical analysis used in this study were fi:equency, mean, $\chi$$^2$-test, t-test and one-way ANOVA. The average JDI scores for dieticians and foodservice employees were 127.31 $\pm$ 24.51 and 136.78 $\pm$ 19.18, respectively. The foodservice workers surveyed in this study were found to be more satisfied with the work itself, the supervision and the colleagues than with the pay and the promotion. While dieticians were more satisfied with the promotion and salary, foodservice employees were more satisfied with work salary, and colleagues. The foodservice worker's demographic variables including age, education, work experience, school type and job type were significantly related to the level of job satisfaction.

This study was conducted to compare job satisfaction and factors related to job satisfaction between permanently and temporarily employed dietitians in school foodservices in the Gyeongsangnam-do area. A total of 204 questionnaires were used in the final analysis. The average age, length of employment, and monthly wage of temporarily employed dietitians was significantly lower than those of permanently employed dietitians. However, there was no significant difference of overall job satisfaction between permanently and temporarily employed dietitians, although the average pay, welfare benefits, and promotion factors for permanently employed dietitians was significantly higher. Work and pay factors had significant effects on the overall job satisfaction of permanently employed dietitians, while work factors and work atmosphere had significant effects on the overall job satisfaction of temporarily employed dietitians. In conclusion, there was a significant difference in overall factors related to job satisfaction between permanently employed dietitian and temporarily employed dietitians. The pay, welfare benefits, and promotion condition of temporarily employed dietitians should be improved to ensure the efficient management of the school foodservice workforce in the future.
