The purpose of this study is to analyze how the satisfaction of Korea life and attitude on sending information is influenced by the information cognition rate of Korea before influx to Korea. The method used for this study was to survey migrant workers in Busan and Kyeongnam area. The results show a tendency towards a higher information cognition when the information was acquired through manpower supply agencies and media information. In addition, among the variables of information cognition, when 'socio-economical' factor was high, the satisfaction rate of Korea life tended to be higher. Also, when the 'workplace environment satisfaction' factor was high, attitude on sending information tended to be positive. Based on those results, this study presented measures for establishing information policies, such as provision of high quality information, diversification of information route which are necessary for migrant workers.

김희재(Hee-jae, Kim),김현숙(Hyun-suk, Kim) 중앙대학교 문화콘텐츠기술연구원 2013 다문화콘텐츠연구 Vol.0 No.14

이 연구는 사회통합의 관점에서 외국 이주민의 사회통합을 위한 생활체육 참여의 필요성과 활성화 방안을 모색하였다. 이를 위해 외국 이주민의 체육활동에 관한 선행연구를 분석하여 체육활동의 실태와 문제점 등을 파악하고 생활체육의 참여를 활성화시키기 위한 방안이 무엇인지를 살펴보았다. 외국 이주민들이 생활체육에 활발하게 참여하기 위해선 첫째, 외국 이주민의 생활체육 활동을 장려할 수 있는 법·제도가 마련되어야 하고, 다민족사회로의 이행이라는 장기적 틀 속에서 정책이 수립되어야 하며, 정책이 제대로 시행될 수 있도록 정책 네트워크가 형성되어야 한다. 둘째, 외국 이주민이 쉽고 편리하게 생활체육 시설을 이용할 수 있도록 기존시설을 개방하고, 다양한 방식으로 정보를 제공하는 것이 필요하다. 셋째, 외국인 이주민의 다양한 삶의 패턴을 반영한 프로그램의 개발과 더불어 가족과 함께 할 수 있는 인프라의 구축도 필요하다. 마지막으로 기획의 과정에 외국 이주민을 대상화한 프로그램을 지양하고 지역사회 주민의 일원으로 자발적으로 참여를 유도할 수 있는 프로그램이 모색되어야 한다. This study came up with necessity of sport for all for immigrants social integration and tried to find strategies how to activate foreign immigrantss participation in life sports. For this, we used earlier studies to deal with about foreign immigrantss sports activity conditions. As a result, we have came up with solutions to activate foreign immigrantss participation in life sports as following. First, the government has to revise 「Sport Promotion Act」for foreign immigrantss sports support or establish regulations. And the government has to formulate sport policy for foreign immigrants on a longer perspective. Second, in order to work an efficient way, schools and physical training facilities in the community have to open athletic field to immigrants and the government has to give immigrants various and native informations. Third, the government has to develop programs that reflects contemporary immigrants life patterns and to build up infrastructure for sport activities with their family social standing. Lastly, the government has not to objectify immigrants during the process of policy and seek the programs that foreigners and Koreans have to take part in sport programs voluntarily.

1. CONTENTS (1) RESEARCH OBJECTIVES This study aims to analyze the determinants of Seoul's apartment rent, focusing on the effects of amenity on the apartment rents. (2) RESEARCH METHOD This study was used by ordinary least square model(OLS) and three different spatial econometrics model(SAR, SEM, SAR). We included four types independent variables into the hedonic price model: apartment structural variables, accessibility variables, locational variables, and amenity variables. As proxy variables for amenity, we include five variables: distances to general parks, neighborhood parks, children parks, sports parks, and water-front parks. (3) RESEARCH FINDINGS In the results of this study, the most importantly, accessibilities to general parks, neighborhood parks, and waterfront parks are negatively related to apartment rents. 2. RESULTS The major findings can be summarized as follows. First and most importantly, accessibilities to general parks, neighborhood parks, Children pakrs and waterfront parks are negatively related to apartment rents, while sports parks have not significant signs, indicating that parks around apartment complexes contribute to increasing apartment rents, but sports parks do not. Second, all the apartment structural variables except building age are positively related to apartment rents at a 1% significant level. Third, apartments closer to subway stations, hghway interchange, and arterial road are likely to have higher rents. Fourth, apartments with higher accessibility to elementary schools, to department stores, and to the CBD and subcenters are likely to have higher rents, while apartments closer to the big box retailers are likely to have lower rents.

This paper explores the national identity and the attitudes towards immigrants among Korean and Japanese university students(below, KUS, JUS). In order to this research, we used cross-national comparable data from Korea and Japan researched at the institute for social Science Research in PNU. and analyzed by factor analysis, t-test. The results are as follows. First, the national identity was examined by national attachment, national pride, qualification of nation. In the national attachment and the national pride, JUS was generally higher than KUS. And the qualification of nation of KUS divided by two factors, that is, civic and ethnic factor, whereas that of JUS had not divide. But there seemed that KUS had strong civic identity and JUS had strong ethnic identity. Second, the attitudes towards immigrants was examined by social distance, attitudes about multicultural society, perceived threat. In the social distance, KUS were generally similar JUS, but JUS were more acceptable than KUS for international marriage. In the attitudes about multicultural society, KUS were very similar JUS, but KUS recognized positively and JUS recognized negatively. In the perceived threat, KUS concerned than JUS about taking jobs away from immigrants, damage of lineage and culture, and JUS concerned than KUS about increase of social problems related immigrants. In the attitudes of multicultural policy, KUS were more higher than JUS to support foreign school, wheres JUS were higher than KUS to qualify foreigners as voter.
