The purpose of this study was to investigate the effects of family cohesion and self-care agency on the quality of life in community-dwelling elderly. Using a descriptive survey design, data were collected during September 2-20, 2016 by distributing questionnaires to and retrieving them from 197 elderly participants aged 65 years or older in two senior welfare centers located in "B" metropolitan city. Results showed that family cohesion of community-dwelling elderly was significantly positively correlated with their self-care agency (r=.434, p<.001) and quality of life (r=.544, p<.001), while self-care agency was significantly positively correlated with quality of life (r=.571, p<.001). The factors that had the biggest effect on the quality of life in community-dwelling elderly were identified in the order of self-care agency (${\beta}=0.413$, p<.001) and family cohesiveness (${\beta}=0.365$, p<.001). These variables were found to have an explanatory power of 42.8% for quality of life (F=74.31, p<.001). Therefore, a strategy to improve self-care agency and family cohesion may be helpful in improving the quality of life in community-dwelling elderly.

It is the purpose of this study to investigate the change of stream water quality in upper stream of Dongjin river, and to give the basic information for the conservation of water quality. Water samples were taken periodically at 9 sampling sites during 8 months from March to October in 2002. The results of this study were as follows : 1. The water temperature and pH of stream water were ranged $9.0{\sim}29.4^{\circ}C,\;6.48{\sim}9.33$, respectively. The COD values of stream water was ranged from 0.60 to 19.06. The contents of T-N and T-P mainly affected by the livestock wastes, and agricultural activity were $1.88{\sim}6.74\;mg/L$, ND(not deleted)${\sim}0.50\;mg/L$, respectively. 2. The SS, DO and BOD values of stream water were ranged $0.4mg/L{\sim}274.0mg/L$, $0.5{\sim}6.0\;mg/L$, and $7.3{\sim}13.7\;mg/L$ respectively. 3. The cation is one of the important components in analysis of stream water quality. The contents of analysis, $Ca^{++},\;Mg^{++},\;Na^+$ and $K^+$ were ranged $1.96{\sim}11.08\;mg/L$, $1.21{\sim}6.16\;mg/L$, $3.38{\sim}18.44\;mg/L$, $1.12{\sim}7.96\;mg/L$, respectively. SAR was ranged $0.31{\sim}1.63$ below 2.0. The contents of cation showed in the order $Na^{++}>Ca^{++}>K^+>Mg^+$. 4. The contents of heavy metal Zn, Cu, and Pb were $ND{\sim}0.071\;mg/L$, $ND{\sim}0.012\;mg/L$, and $ND{\sim}0.043\;mg/L$, respectively. Cd was not detected in all samples. 5. As a result of these researches showed water quality in upper stream watershed of Dongjin river more affected by livestock wastes and living sewage than agricultural activity.

Since commercial operation of Kori-1 nuclear power plant in 1978, twenty units are under operation and six units are under construction at 2011 present. Nuclear power become a main energy source in our country. However, the plant was constructed by a USA vendor in its beginning period, the Quality Assurance requirements of USA was applied. Even though Quality Assurance requirements were newly established to the Korea Atomic Energy Act, its contents are quite similar to those of USA. And 10 CFR 50 App.B, ASME NQA-1 apply to most of nuclear industries as a quality assurance plan. In this paper, Quality Assurance requirement of domestic nuclear industries has been investigated and applicable method of ISO Quality Assurance application to the nuclear industries is suggested by a comparison ISO 9000 and nuclear quality assurance specification.

In this study, the effects of MTBE contents as oxygenates in gasoline on exhaust emissions and fuel economy in MPI and GDi vehicles have been investigated. Various oxygen contents have been selected such as 0, 1.0, 2.3 and 2.7 wt%. FTP-75 and HWFET modes as fuel economy test methods which are widely used in Republic of Korea and US were applied to investigate exhaust emissions from the test vehicles. Emissions of CO, NMHC and NOx did not show significant correlation with oxygen contents in gasoline fuels, although having slight difference with these contents. In addition, CO2 emissions were not significantly changed with respect to oxygen content. But in case of warm-up and FTP-75 and HWFET modes including high speed regimes, CO2 emissions showed inverse correlation with oxygen contents. Particulate number concentration was inversely proportional to the oxygen contents, having the minimum value at the condition of 2.3 wt%. In case of fuel economy through carbon balance method, the highest value has been obtained at 2.3 wt% and there was positive correlation with oxygen contents and fuel economy.

IT service is becoming a critical business operation in the age of information revolution. In providing IT services internally to other functions of the corporation and externally to other organizations, sharing of knowledge between business people and system people is known to become more and more critical for successful IT services. Purpose of this research is to examine the impact of IT service quality on knowledge sharing activities between IT service providers and users. Theoretical research model, through an extant literature review, is proposed here, consisting of IT service quality, relationship quality(satisfaction, trust and commitment), and the level of knowledge sharing activities. Survey results of 183 users indicates that IT service quality significantly influences commitment through satisfaction and trust, which in turn influences the level of knowledge sharing activities. Also, interestingly, satisfaction and trust do not directly influences the level of knowledge sharing,but indirectly, through commitment.
