The objective of this study is to review the methodology of economic analysis of fishing ports by examining the economical feasibilities of a national fishing port (Jeongja Port) in Ulsan. This study utilized market value evaluation method to measure the benefits and costs related to the development of ports. The benefit variables are income effects resulting from the developments while the cost variables are sum of construction costs and maintenance costs. The income effects are measured in two ways: (1) income from individual project resulting from the developments, (2) the income effects by utilizing investment multipliers. The results shows that the BC ratio (Benefits/Costs) of Jeongja port by using (1) income from individual project resulting from the developments was 1.07 while the BC ratio by using (2) the income effects by utilizing investment multipliers was 1.10 due to a relative short period of useful life for investment multipliers. However, the income variable utilizing investment multipliers is more sensitive to the period of duration than the income variable from individual project.

The purpose of this study is to assess individual decisive factors for distribution of medical specialists in Korea. A data set was constructed using several published data sources. including the Korean Medical Association's physician master file as a principal source for physician information. Linear logistic regression analysis was performed to assess the relationship between the location of private specialist clinic for practice with six variables related with individual characteristics: age. sex. location of postgraduate training hospital. location of medical school graduated, size of hospital for training, and specialty. Analysis showed that location of practice. classified into urban and rural areas, was significantly associated with the variables of sex. location of postgraduate training hospital. location of medical school. In addition, significant association was found between the location of practice which was categorized into "near-Seoul area" and others, and sex, location of postgraduate training hospital. and location of medical school. We could conclude that to improve area maldistribution of physicians locations of hospitals for training and medical schools have to have the highest priority in the policymaking.icymaking.

In this paper, we attempted to theorize the multi-faceted impacts of smart work on economic activities. In this vein, we adopted socio-economic perspective which includes individual, firm, and social support aspects, and explored the variables related to the quality of life among them. First, smart work patterns are categorized as telework, mobile office, teleconferencing, and social collaboration. And relevant variables are extracted with reference to industrial cases and relevant literatures which investigated economic impacts of digital convergence. Next, with the data collected from experts, following delphi method, validation of variables and explorations of significant factors affecting quality of life were conducted by adopting stepwise regression method. The distinguishing traits of this research are two-folds. The one is the investigation of social support and quality of life aspects of smart work, which has been relatively limited in the digital convergence research field. The other is the comparative analysis of smart work advantages by distinguishing individual and firm aspects separately. The result offers useful insights for socio-economic perspective researches on digital convergence application area.

본 연구는 개인의 기업가적 지향성이 창업의도에 긍정적인 영향을 미치는 것을 확인하고, 인지역량과 기업가에 대한 사회적 인식이 개인의 기업가적 지향성과 창업의도 간의 관계에서 매개변수로 역할을 하는지 규명하고자 하였다. 본 연구의 결과는 다음과 같다. 개인의 기업가적 지향성은 창업의도, 인지역량, 기업가에 대한 사회적 인식에 정(+)의 영향을 미쳤고, 인지역량과 기업가에 대한 사회적 인식이 높을수록 창업의도가 높아지는 것을 확인하였다. 더불어, 개인의 기업가적 지향성과 창업의도 간의 관계에서 인지역량과 기업가에 대한 사회적 인식은 병렬 매개효과가 있는 것으로 규명하였다. 이를 토대로 그동안의 연구가 미진했던 개인의 기업가적 지향성과 창업의도 간의 연구의 이론적인 토대를 마련하였고, 인지역량과 기업가에 대한 사회적 인식의 매개변수를 밝힘으로써 학문적인 확장을 가능하게 할 것이다. 끝으로, 개인의 기업가적 지향성과 관련한 실무적인 기초자료로 활용이 가능할 것이다.

In the study of married couples, there has been a great lack of analysis of the factors affecting the marital satisfaction of spouses until now. In this study, the subjects were couples living in Seoul or Gyeonggi Province. The data collection period was November 20 to December 20, 2009, and data ond 184 couples were collected and used for the analysis. The SPSS 17.0 program was used for the analysis. The main findings of this study are as follows: First, the husbands' marital satisfaction was higher than that of the wives. And the variables of spousal support, alternative comparison level and marital dissolution disability were also found to be statistically significant according to gender. Second, it was confirmed that the self-variables had a greater effect than partner variables on couples' marital satisfaction. Third, the influential factors of the marital satisfaction of husbands and wives depended on the individual resource variables (self-esteem, health of origin of family, parenting efficacy), the couple relationship variables (spousal support, spousal similarity, recovery attempts), and the level of marital alternatives.

This research has analyzed the differentiated influence of organizational variables(an organization's learning culture and organizational support networks) and personal variables(the individual's motivation to learn and self-efficacy) on the process of gaining and using of knowledge. These two variables have been regarded as the major variables for the successful learning of 6Sigma, according to Social Cognitive Theory. In addition, this research has proven the role structure of the abovementioned two variables through a suitable methodology(Hierarchical Linear Model). In regard to this methodology, the different hierarchical level of the personal variable and organizational variable was especially focused on, and the effect of interaction between the high level and the low level was considered in detail. Considering the current situation, in that the importance of organizational factor and personal factor has been emphasized but the accurate role of each variable has not been verified, the research model is thought to help to establish an effective strategy to implement 6 Sigma.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

이 연구의 목적은 위험해석모형을 적용하여 범죄두려움의 영향요인을 검증하는 데 있다. 특히, 기존의 연구들이 위험해석모형에서 제시된 미시적 개인요소를 포함하지 않고 있어 이 연구에서는 미시적 개인요소, 지역사회요소, 범죄 위험의 인지, 범죄두려움 등을 주요 변인으로 포함하였다. 이 연구에 사용된 자료는 형사정책연구원(2012)에서 실시한 '전국범죄피해조사'의 2차 자료를 활용하였으며, 해당 변인들이 범죄두려움에 미치는 개별적인 영향력을 검증하고, 위험해석모형에서 제시된 인과적 경로관계를 규명하기 위해 2단계의 다중회귀분석과 Sobel Test를 실시하였다. 분석결과, 범죄 위험의 인지가 높을수록, 여성일수록, 지역사회가 무질서하다고 인식할수록, 연령이 낮을수록, 범죄피해를 경험할수록, 학력이 높을수록, 소득수준이 높을수록 범죄두려움을 보다 많이 인식하고 있었으며, 그리고 위험해석모형에서 제시된 인과적 경로관계는 학력을 제외하고 모두 유의미하게 제시되었다.
