The purpose of this study is to investigate the effects of the job stresses perceived by R.O.K. naval crews on turnover intentions and job satisfactions. Especially, this study aims to derive the policy implication for the trait characteristics by comparing the job attitude between the surface naval ship and submarine crew. For this purpose, we surveyed 1,000 naval crews. Then, multiple regression analysis was performed. Next, a T-test was conducted to test statistical significance of group differences. First, the job stresses perceived by naval crews were higher in the order of physical environments, overworks, compensation incompetence, lacks of autonomy, and conflicts with people. Second, the job stresses perceived by submarine crews were higher than that of surface naval ship crews. It was also proved statistically significant by the T-test. Third, the physical environments, lacks of autonomy, conflicts of relativity, and inadequate compensation stress have a positive statistically significant effect on turnover intentions of naval crews. Fourth, lacks of autonomy, conflicts of relativity, and inadequate compensation factors have a statistically significant negative effect on the job satisfactions of naval crews. Finally, multiple regression analysis was performed between the independent and dependent variables of the naval crews, and the policy implications were derived.

The purposes of this study were to reveal the relation of consumer value variables and to identify the difference of clothing information exploration behaviors on consumer value variables. The data were collected from 267 college women residing in Gwangju using a Questionnaire to general value, clothing value, consumption value and clothing information exploration behaviors. It were analyzed with factor analysis, cluster analysis, T-test, ANOVA and multiple regression analysis using statistical program SPSS 10.0. The results of this research were as follows: 1. Only one factor of general value had a significant influence on 'practical' of clothing value. All of general value and clothing value had a significant influence on the whole consumption value. 2. Clothing information search behaviors was divided into three factors: 'variety pursuit' 'active information collection' and 'uniqueness pursuit'. General value group had a significant difference in 'variety pursuit' and 'active information collection' behavior. Clothing value and consumption value group had a significant difference in all factors of clothing information search behaviors. By implication, this study could be explain each contributions of consumer values and suggest useful variable of consumer values in future clothing behaviors research.

강우의 관측망 확장과 위성 자료 및 기후 모델을 이용한 격자 단위자료가 개발 및 보급됨에 따라 다양한 자료의 분야별 활용성에 대한 연구의 필요성이 제기되고 있다. 본 연구에서는 지역 기후 모델 산출물의 오차 보정을 위한 격자 관측자료의 활용성을 평가하였다. 또한 통합 분포형 수문모델을 이용하여, 보정한 기후모델 결과의 수문 모의를 위한 기후 입력 자료로써의 적합성을 검토하였다. 보정된 결과는 각 관측자료의 월별 평균 강우량과 공간 분포를 비교적 잘 재현하였다. 한편 연강우량 시계열에 있어 그 양상은 잘 재현된 가운데 보정되지 않은 오차를 일부 포함하는 것으로 나타났다. 이는 점 관측자료로부터 추정된 시험 지역내 172개 소유역에 대한 일평균 강우량 자료와 비교해 볼 때 관측자료의 형식이나 정확성보다 기후모델의 불확실성에 기인하는 것으로 판단된다. 수문 모의 결과, 격자 자료를 이용하여 보정한 강우 입력자료는 수문 모델의 검보정에 이용된 소유역 단위 강우 자료를 이용한 결과에 상응하는 활용성을 보여주었다. 또한 강우의 공간 분포를 고려하지 않고, 시험유역 전체에 대한 평균 강우량을 입력 자료로 이용한 결과를 통해 기후 자료의 공간 분포와 관측 밀도의 중요성을 확인하였다.

A survey of risk perception in South Korea was conducted in 2007 to evaluate relative riskiness of typical industrial and technological risks. This article summarizes the characteristics of risk perception using psychometric analyses. The survey with a sample size of 1,194 reviews the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, nuclear power generation, and newly-introduced risks. Six categories of risk identified by a factor analysis show that the level of perceived risk does not correspond to the statistical level. Psychometric analyses including voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity demonstrate that voluntary, familiar and immediate risks are perceived as less risky than involuntary, unfamiliar and delayed ones. Risk communication is critical in reducing the discrepance between objective and subjective level of risk. However, the amount of risk information does not always justify a successful risk communication. A safety policy, risk communication strategy in particular, should take into account diverse dimensions of risk reviewed by psychometric analyses in the study. Social policy toward safety can be improved by integrating policy, human, and social factors as well as technological advances.

Since the Republic of Korea had been registered as the 24th member of OECD DAC in 2009, recent trend of Korea's ODA has showed drastic increase including agriculture and rural development sector. Particularly, various rural development projects have been implemented adopting development experience and methodology of Saemaul Undong (SMU, New Village Movement). This study implemented statistical analysis between villagers' participation and achievement of rural community development project, based on practical data out of 'Saemaul Undong Project in Myanmar', to suggest meaningful implication in terms of participatory rural development. It emphasized the importance and necessity of villagers' participation in rural development through regression analysis that proved positive correlation between villagers' participation and rural development project. It proves that income-generation part has significantly greater influence than capacity-building and living environment part in terms of rural community development project: Based on the analysis, comparing impact of each independent variable, income generation has 1.88 and 1.68 times greater impact than capacity-building and living environment respectively. The result, on the other side, rather raise the importance of careful consideration for project design and implementation to harmonize those three parts altogether especially rural development for developing countries: capacity-building and living environment parts suggests essential foundation to make income generation successful that enables to secure project achievement and sustainability.

격납용기 구분방 내에서 정화한 열전달 상관식을 얻기 위해 HDR 실험 자료들을 통계적 인 방법으로 분석하였다. 세가지의 blowdown 시험, 즉 V.42, V.43 and V.44를 통해 얻어진 열전달 자료들이 상관식을 유도하는데 사용되었다. 이미 Uchida에 의해 제안되었던 air-to-steam 질량비는 이 실험에서도 역시 가장 중요한 인자로 입증되었다. 이 연구에서는 Uchida의 열전달 상관식으로 만족되지 않은 실험자료들을, 격납용기 대기와 벽 표면의 온도차의 함수로, 또 대기 압력의 함수로 표시하여 수정하려고 시도하였다. 이 종속성외에도 대기의 난류도와 시간에 따른 인자가 고려되어야 한다. 그러나 HDR 계획에서는 흐름속도의 측정 자료가 부정확하기 때문에 정량적인 관계식의 유도는 힘들다. 다만 열전달 계수와 온도 차이의 관계가 밀접하다는 사실을 밝혔으며 특히 강제순환 조건에서 더욱 이 관계는 명백해짐을 볼 수 있다.

Purpose - This paper investigates the structure of exports across countries in terms of value added. Exports value added is examined under two categories, domestic and overseas. Using a statistical classification method by distance based on these two value added categories, this paper estimates the similarity of exports value added across countries including Korea. Design/methodology - The model of study is to employ a generalized distance function and then derive the Manhattan and Euclidean distances. The paper also performs cluster analysis using the Partitioning Around Medoids (PAM) and hierarchical methods to classify the 44 sample countries considered in this study. Findings - Our main findings are as follows. The 44 countries can be classified under 5 groups by their domestic and overseas value added in exports. Korea has a sandwich global value chains (GVCs) position between Japan, China, and Taiwan in the East Asian region. Originality/value - Existing papers point out the double counting problem of trade statistics as the intermediate goods trade across borders increases. This paper addresses the double counting problem by using the World Input-Output Table. The paper shows the need to explore the similarity of value added in exports structure across countries and investigate the GVCs position and role of each country.
