This study is intended to investigate the effects of customers' emotional response upon behavioral intention with taking customers who visited Korean restaurants into account. Luxury Korean restaurants where we apply to this study are selected by the food service industry association of Busan-metro city among the model restaurants. For this aim, designing a research model and drawing a hypothesis were carried out with a basis of advanced research. In data processing, SPSS win package 15.0 statistical program was used to verify the hypothesis through frequency analysis, reliability analysis, factor analysis, and regression analysis. The result of the analysis on the effects of physical environment factor upon domination among emotional response could be summed up as follows. Employee and geniality factors turned out to exercise a significant impact on domination, convenience and cleanliness turned out not to. The result of the analysis on the effects of physical environment factor upon arousal among emotional responses could be summed up as follows. Cleanliness and geniality factors turned out to exercise a significant impact on evocation, convenience while employee factor turned out not to. As a result of the analysis on the effects of emotional response upon behavioral intention, domination and evocation factors among emotional responses had a statistically significant impact upon behavioral intention. From the findings of the study, it became evident that dining-out customers might regard luxury Korean restaurants as a space for experiencing various emotions by physical environment rather than for dining and meeting for friendship. To induce emotional response is therefore expected to help a company to promote the practical improvement in achievement over various aspects such as behavioral intention.

Three study areas of Kwanak campus(Seoul National University), Gapyung and Boeun were selected and classified according to bedrock types in order to investigate soil-gas radon concentrations. Several soil-gas samples showed relatively high radon concentrations in the residual soils which derived from granite bedrock. It also showed that water content of soil and the degree of radioactivity disequilibrium was a secondary factor governing radon emanation and distribution of radon radioactivity. The results of radon concentrations and working levels for forty rooms in Kwanak campus, Seoul National University, showed that indoor basement rooms under poor ventilation condition can be classified as high radon risk zone having more than EPA guideline(4 pCi/L). Some results of section analysis which was surveyed in the fault zone of Kyungju and Gapyung area confirmed the existence of fault-associated radon anomalies with a meaning of radon risk zone.

The object of this research is to examine the factors leading to intercompany win-win by finding the antecedents and consequences that affect a supplier's fairness perception. We assume that the antecedent factors of a supplier's fairness perception are vertical coordination, cooperation support, information sharing, and legalistic plea. We assume that the consequential factors of a supplier's fairness perception are supply chain dependence and supply chain flexibility. The object industry is an electronic parts manufacturing company. We tested our model by using the SPSS 17.0 and the LISREL 8.5. For measurement validation, we verified by using a confirmatory factor analysis and a reliability analysis. For hypothesis analysis, we did a path analysis with the LISREL 8.5. By checking the modification index and expecting parameter changes, we modified the model. First, the buyer's vertical coordination had a positive effect on the supplier's distributive fairness perception and procedural fairness perception. Second, the buyer's cooperation support had no effect on the supplier's distributive fairness perception and procedural fairness perception: we suppose that the buyer's requests were burdensome, although they cooperated with the supplier. Third, the buyer's information sharing had a positive effect on distributive fairness perception but had no direct effect on procedural fairness perception. Fourth, the buyer's legalistic plea had a negative effect on the supplier's distributive fairness perception. and a negative effect on the supplier's procedural fairness perception at a 0.1 significance level. Fifth, although procedural fairness perception had no direct effect on supply chain dependence, fairness perception had an effect on supply chain dependence and supply chain flexibility both directly and indirectly.

This study is intended to analyze how emotional reaction based on consumption experience of dining at Korean traditional restaurants affects comsumer's repurchase intention. These restaurants are chosen from lists of high quality Korean traditional restaurants designated by the Restaurant Association in Busan. And then a model for the study is designed based on preceding studies and hypotheses are extracted. A statistical package program, SPSS WIN Version 18.0 is used for frequency analysis, reliability analysis and factorial analysis and regression analysis to verify the hypotheses. As the result of verifying how experience of dining at a Korean traditional restaurant affected arousal among emotional reactions, the symbolism factor and the variety factor were all proved to be meaningful, whereas the amusement factor was proved to be meaningless. As the result of verifying how experience of dining at the restaurant affected dominance among emotional reactions, the symbolism, amusement, and variety factors were all proved to be meaningful. As the result of verifying how emotional reactions affected consumer's repurchasing, the arousal and dominance factors were all proved to be meaningful. Moreover, as the result of verifying how experience of dining at the restaurant affected consumer's repurchasing, the variety and amusement factors were all proved to be meaningful, whereas the symbolism factor was proved to be meaningless.

To know characteristics of water quality in coastal sea around the Keum river estuary in summer, we studied the water quality of surface, middle and bottom level during Jun e～september, 1998. The mean concentrations of COD, DIN, DIP & chlorophyll-a were 1.36mg/L, 28.60㎍-at/L, 0.48㎍-at/L and 4.14㎍/L, respectively, which were over eutrophication criteria in sea water. After the Keum river dyke was constructed, seasonal freshwater discharge was largely changed. About 80% of total annual freshwater discharge was concentrated in summer as rainy season from July to September. The correlation coefficient of DIN versus salinity was shown to be high, and thus the concentration of DIN was closely related to freshwater discharge. Maximum Chlorophyll-a concentration was occurred in September, due to increased DIP concentration, high water temperature and low salinity after heavy rainfall in August. The results of Principal Component Analysis showed that the first factor represented a series of eutrophication factors, the second factor w3s a valiance of seasonal fluctuation, and the third was a variance of progress of mass change.

삽교호유역에 위치한 19개 수질관측지점에서 측정된 월별수질자료를 이용하여 수질관측지점을 2개에서 7개의 수질특성으로 분류하였으며, 그에 따른 수질요인분석을 실시하였다. 군집분석결과 삽교호유역의 각 하천은 개개의 수질특성을 보이고 있으며, 삽교호, 삽교천, 무한천 및 곡교천의 4개 그룹으로 나눌 수가 있었다. 수질분석결과에 의하면 삽교호에서는 부유물질의 농도가 다른 하천보다 높았는데 이는 하천으로부터 유입되는 풍부한 영양염에 의한 식물플랑크톤의 생물량 증가에 따른 것으로 사료된다. 또한 곡교천의 수질은 다른 하천에 비해 생화학적산소요구량은 $3.5\~4.8$배, 화학적산소요구량은 $1.7\~2.5$배 높았으며, 전반적으로 삽교호 유역의 수질은 부영양상대를 훨씬 초과하였다. 요인분석결과 삽교천과 무한천은 농경지와 주거지에 의한 수질요인이 지배적이었고, 곡교천은 천안도시지역으로부터 유입되는 과다한 유기물유입과 상류에 위치한 하수 처리장의 영향을 복합적으로 받고 있는 것으로 사료된다. 삽교호의 수질은 삽교천과 무한천 및 곡교천에서 높은 부하를 보인 인자가 주된 오염요인으로 나타났다.

화약의 힘을 결정하는 요인은 폭속, 가스량, 폭발열등이 있다. 이중 폭속은 화약의 힘을 결정하는 중요한 요인이다. 이러한 폭속을 결정하는 조건은 화약내 구성성분에 따라서 달라진다. 그러나 동일한 화약조성일 경우 폭발속도는 공기중과 같은 개방상태, 천공 내와 같은 밀폐상태에서 차이가 있을 것이며, 또한 이론상 약경, 장전밀도, 뇌관의 위력, 장전방법 등에 의해 지배를 받는다고 알려져 있다. 이에 본 연구에서는 국내 산업용화약류를 대상으로 상기의 조건들을 달리하여 폭속을 측정하고, 그 결과를 바탕으로 실제 폭약의 폭속에 영향을 미치는 조건을 찾아내고 이러한 조건의 변화에 따라 폭속이 어떻게 변화는 지를 알아보고자 한다.

Recently, dating violence has emerged as a serious social problem, but there is not enough research on controlling behavior among the subtypes of dating violence. Thise study explored the relationship between psychological entitlement and controlling behavior, and the mediation effect of social dominance orientation and social comparison orientation. Furthermore, the study examined if the mediation effect of social dominance orientation between psychological entitlement and controlling behavior differed by gender. As a result, the higher the level of psychological entitlement, the stronger the level of social dominance orientation, social comparison orientation, and the controlling behavior. In addition, the stronger the level of social dominance orientation and social comparison orientation, the more frequently was the occurance of the controlling behavior committed. The level of social dominance orientation mediated the relationship between psychological entitlement and controlling behavior. The level of ability comparison orientation mediated the relationship between psychological entitlement and controlling behavior. The mediation effect of social dominance orientation between psychological entitlement and controlling behavior was moderated by gender. In other words, the mediation effect of social dominance orientation between psychological entitlement and controlling behavior was significant for the male, but not for the female. The limitations of the study and suggestions for further research were discussed.
