This study aimed (a) to examine the association between chronic illness and multidimensional disability(i.e., psychological/emotional functions, activity capacity, and participation frequency) among older adults with disabilities, (b) to investigate the effect of formal and informal supports on multidimensional disability, and (c) to analyze the moderating effects of formal and informal supports on the association between chronic illness and multidimensional disability. This study used 2014 Korea Welfare Panel Study(the 9th wave) data and 450 older adults with disabilities aged 50 and over were selected as the study target. The research model was analyzed by structural equation modeling using IBM AMOS 22.0. Based on the ICF framework developed by WHO, health condition was measured by the level of chronic illness; psychological/emotional functions were measured by health satisfaction, self-esteem, and depression; activity capacity was measured by ADLs and IADLs; participation frequency was measured by the total number of social activities joined; formal support was measured by the total number of formal welfare services for people with disabilities utilized; informal support was measured by perceived social support. The findings showed that the level of chronic illness was negatively associated with psychological/emotional functions among the older adults with disabilities. The informal support positively affected psychological/emotional functions and activity capacity, whereas the formal support showed the opposite result. That is, the formal support negatively influenced activity capacity and showed a moderating effect on the association between the level of chronic illness and the psychological/emotional functions in a reverse way. Based on the results, practice and policy implications for alleviating disability level among the older adults with disabilities were discussed.

Structural flood defensive alternatives have been evaluated based on economic feasibility, riskiness of safety and sustainability. Social problems associated with structural flood defensive alternatives such as dams, flood control channels, etc. are currently issued. The evaluation items of policy presented in KDI(2001) are should be modified in order to resolve the social problems. Hence, this study conducted a questionnaire survey of public servants, researchers, and engineers to obtain how to determine evaluation items for policy assessment and to compute their weights in the analytic hierarchy process. This study also compared the weights of the items in KDI(2000) with the weights from the survey in this study. The policy assessment weight was estimated higher than KDI(2000). This result suggests that social awareness increases and the analysis of policy becomes important for selecting optimal structural defensive alternatives.

This study aims to diagnose research trends and to deduct implications from meta analysis of entrepreneurship studies in the Asia Pacific Journal of Small Business (APJSB), one of the most well-known academic journals in management and entrepreneurship field in Korea. Frequency and crossover analysis are executed in multi-dimensions by time period, topic, author, research level, data, and methodology by complete enumeration of every published paper for 40 years in APJSB which included core terms of entrepreneurship in its title, abstract, or keywords. From objective and quantitative schematization of research trends and characteristics of entrepreneurship studies, novel improvement plans which are highly applicable in research fields are suggested such as diversification of studies from ecosystem perspective, identification of authors, and standardized system of extended abstract of research papers. Implications and suggestions derived from the results propose future research directions and tasks when entrepreneurship studies have been rapidly increased. Furthermore, the innovation plans of management system of journals and papers are expected to contribute promotion of entire studies by significantly reducing trial and error, and inefficiency in research process.

Feature selection or variable selection is a data mining scheme for selecting highly relevant features with target concept from high dimensional data. It decreases dimensionality of data, and makes it easy to analyze clusters or classification. A feature selection scheme requires an evaluation function. Most of current evaluation functions are based on statistics or information theory, and they can evaluate only for single feature (one-dimensional data). However, features have interactions between them, and require evaluation function for multi-dimensional data for efficient feature selection. In this study, we propose modification of FSDD evaluation function for utilizing evaluation of multiple features using extended distance function. Original FSDD is just possible for single feature evaluation. Proposed approach may be expected to be applied on other single feature evaluation method.

This study aims to investigate the overall relationship between the deterring and facilitating factors in export activities of the small and medium export companies. Nine export deterring factors are analyzed by multinational dimensional scaling(MDS) method to identify key dimensions underlying those factors. Perceptual mapping shows that some factors such as brand image, operating capital and e-trade infra are found similar in its degree of difficulties in export activities. Regression analysis shows that government export promotion measures might play an effective export facilitating factors to ease the export deterring factors like market information and manufacturing skill. Whereas difficulties arising from e-trade infra, operating capital, and brand image might be eliminated by internal competency of company, difficulties from distribution channel might be lessened by overseas orientation of chief executive of company.

As the service industry has been getting increased attention as the core for the national economic growth, in order to promote growth and development of the industry, in-depth research on the workers in the industry has been timely called for. Therefore current study aims to explore the effect of leadership style on organizational citizenship behavior(ie OCB) for increased productivity of workers in the service industry, and the role of multi-dimensional justice in the relationship between them. The findings suggest that transformational and transactional leadership both have positive effect on OCB, implying that application of leadership style that is appropriate to the context may be more important, Also, mediation test of multi-dimensional justice resulted partial mediation effect except for the procedural justice in the relationship between transformational leadership and OCB.

홍수 피해 특성을 파악하고 영향 인자를 평가하여 홍수 피해로 인한 손실을 추정하는 것은 홍수 예방과 피해 저감을 위한 대책 마련 및 정책수립을 위해 매우 중요하다. 이 중 홍수로 인한 주거건물의 피해는 일반 주민들과 직접적인 관련이 있다. 그러나 국내의 경우, 홍수피해 정보를 수집하기 위한 체계적인 조사 방법이 확립되어 있지 않아 주거건물 및 내용물의 피해가 과소평가되는 경향이 있다. 본 연구에서는 주거건물 및 내용물에 대해 홍수피해 정보의 체계적인 수집을 위해 주거건물 설문조사지를 활용하였다. 수집된 홍수피해 정보는 주거건물과 건물내용물의 홍수피해율과 영향인자간의 관계 분석에 활용하였으며, 국내 실정에 적합한 홍수피해 손상함수를 개발하고 적용 및 분석하였다. 분석 결과, 홍수로 인한 주거건물의 피해에 영향을 주는 대표 인자는 건물내 침수심과 출입구 높이로 평가되었으며, 건물내용물에 영향을 주는 인자는 건물내 침수심, 이송잡물로 나타났다. 한편, 주거건물과 내용물에 대한 손상함수를 건물내 침수심을 활용하여 회귀분석을 통해 개발하였으며, 개발된 손상함수는 국내 홍수피해 평가 모델인 다차원법과 비교 평가하였다. 평가 결과, 주거건물 피해액은 다차원법이 크게 산정되었으며, 건물내용물 피해액은 손상함수가 크게 산정된 것으로 나타났다. 본 연구에서 수행한 주거건물과 건물내용물의 홍수피해 영향인자 평가 결과는 홍수피해 저감 대책 수립 및 향후 홍수피해를 추정하는데 활용할 수 있을 것으로 기대된다.

최근 기후변화에 따른 전 지구적인 지구온난화는 단시간의 집중호우와 돌발홍수의 증가로 기존의 기후특성을 변화시키고 있다. 이로 인해, 자연재해의 강도가 강해지고, 재산피해가 커지고 있다. 특히, 내륙에 위치한 도시지역 보다 해안 도시지역은 조위에 따라 홍수위가 크게 영향을 받기 때문에 강우에 따른 피해규모는 더 크게 영향을 받는다. 본 연구에서는 기후변화로 인한 자연재해에 대비하기 위하여 미래 기후변화를 예측하고 해안 도시지역에 미치는 영향을 파악하고자 하였으며, 대상지역으로는 2012년 태풍 산바(Sanba)으로 인해 상당한 인명피해와 홍수피해가 발생한 마산(창원시) 일대를 선정하였다. 본 연구에서는 마산(창원시) 대상으로 빈도-지속기간별 강우와 조위의 영향을 고려한 침수모의를 실시하고자 한다. 또한 2004년도에 개발된 다차원법(다차원 홍수피해 산정방법(Multi-Dimensional Flood Damage Analysis))을 이용하여 조위와 홍수위의 영향을 받은 해안 도시의 경제성 분석을 실시하고, 침수에 따른 피해액을 산정하고자 한다. 본 연구의 결과는 향후 마산(창원시) 일대의 홍수피해 산정과 침수피해 관련 방재 정책을 수립하는데 기초자료로 활용할 수 있을 것으로 기대된다.

The purpose of this paper is to compare the family policies of Nordic countries(Denmark, Finland, Norway, and Sweden) from 1980 to 2002. Three meaningful findings were found. First, there are several different characteristics in the family policies of Nordic countries in which the ideal understanding of similarity has departed from the reality. Especially, the differences of family policies have extensively expanded since 2000s. Second, for the last 20 years, all four countries have focused their efforts on expanding parents' (re)commodification rather than (re)familialization. Third, the countries have changed their direction in family policies. For example, Finland has changed from familialization to commodification during the mid-1990s.
