The Korean cultural heritage protection act, enacted in 1962, is known to have been enacted in imitation of the Japanese cultural heritage protection act. The Japanese law differs from the current law dealing with intangible cultural heritage, folklore materials, and buried cultural properties. The Japanese law was enacted in consultation with the GHQ, and reflected the historical issues at the time of the enactment. Recently, in Japan, GHQ documents have been released and so research on the cultural heritage protection act is carried out. Therefore, it is necessary to understand the meaning and achievements of the Japanese cultural heritage protection act before comparing it with the Korean law. GHQ stipulated the emperor as a symbolic entity in the Japanese constitution and prescribed the country as a liberal democracy. Influenced by this, the cultural heritage protection act was enacted to identify the people's cultural heritage. Accordingly, the cultural heritage protection committee is a private and independent organization in Japan. The committee designates cultural heritage assets, and it operates as the national museum and the cultural heritage research institute. This system was a part of policy changes shifting cultural heritage management to the private sector. Since many cultural heritages are associated with the imperial family, museums were managed by the imperial family. Meanwhile, the Japanese house of councillors persuaded GHQ, which was negative about including intangible cultural heritage in the cultural heritage protection act. The purpose of this idea was to provide the system of the government support for Japanese imperial court music and dance. In addition, folk materials were included with the consent of the GHQ in that they represent the cultural heritages and the academic achievements of the people at the time in Japan. According to the Korean Law, the subject of designation of cultural heritage is the government, and the cultural heritage committee acts as an advisory body with its limited functions. In the early days, the committee confused the concept of intangible cultural heritage and folklore materials. This was because the concepts of cultural property was borrowed from Japanese law and applied to the Korean law without a full understanding. In response, the cultural heritage committee urged the ministry to investigate the current situation in Japan. The cultural heritage committee, mainly consisting of folklore scholars, was confused about the concepts of intangible cultural heritage and folklore materials, but the concept became clear when the enforcement regulations of the cultural heritage protection Act was enacted in 1964.

In this paper we issue some problems occurring when a mobile host moves from a base station to another in a wireless multicasting and propose a solution. In the case of not being in the same multicast group, the old base station will pre-forward data to neighboring base stations to avoid transmission delay. However, if other mobile hosts move at short interval, the old base station may retransmit the same dta to the same neighboring base stations. Also, the old base station should retransmit data if the new base station has already discarded data even if the new base station is a member of the multicast group. In this paper we propose called Information Exchange Scheme (IES). In this scheme, each base station exchanges indirectly the data delivery information with the rest of the base stations in the same multicast group for efficient and reliable multicast and pre-forwards data not retransmitting the same data for minimizing transmission delay when a mobile host moves. We also present how IES is efficient by analyzing and simulating.

The purpose of this study is to analyze empirically relationships between learners' psychological factors, knowledge sourcing behavior and knowledge utilization outcomes and to analyze the mediation effect of social learning and relationships among learners. Another purpose is to understand learners' attitude on social learning and knowledge sourcing behavior. The main results of this study are as follows: First, regression results on relationships among learners' psychological factors, knowledge sourcing behavior, knowledge utilization outcomes show that learners' self-efficacy has a positive effect on social learning activity participation, and goal orientation has a positive influence on group knowledge sourcing and social learning activity participation. Users' experiences of social media has a positive effect on group knowledge sourcing, social learning activity participation and social learning interaction. From a knowledge utilization perspective, published knowledge sourcing positively affects knowledge reuse, knowledge application and knowledge innovation. Dyadic knowledge sourcing has positive influence on knowledge reuse. Group knowledge sourcing affects positively knowledge application and knowledge innovation. Second, social learning activity participation factor has full mediation effect on relationship between learners' goal orientation and group knowledge sourcing, and the relationship between users' experiences of social media and group knowledge sourcing. A relationship among members factor has full mediation effect on the relationship between published knowledge sourcing and knowledge reuse, and relationship between published knowledge sourcing and knowledge innovation. Third, the results of in-depth interview show that learners trust and easily collect knowledge from social network services in general.

무선 Ad-Hoc 네트워크는 노드의 참여와 이탈이 자유롭고 토폴로지의 변화가 많아 악의적인 노드에 의해 데이터의 무결성 및 기밀성 문제와 같은 보안 위협에 노출되어 있다. 또한 악의적인 노드의 참여로 잘못된 라우팅 정보의 삽입을 통해 네트워크 분할이나 잘못된 정보전달 제공으로 노드의 통신장애를 유발할 수 있다. 그러나 현재 이와 같은 무선 Ad-Hoc 네트워크에서의 악의적인 노드를 발견하고 대응할 수 있는 연구가 부족하며, 기존의 악의적인 노드 탐지 기술들[11][12][13][14]은 정상적인 노드임에도 불구하고 거짓으로 신고했을 경우 인증절차 없이 경로를 재탐색하여 최적의 경로를 변경시킴으로서 정상적인 전송환경을 구축하지 못하는 문제점이 있다. 본 논문에서는 다중경로 기반의 보안경로 탐색기술[8]을 이용해 보안경로에 존재하는 중간노드들 사이에서 악의적인 노드를 발견한고, 검증된 최단경로를 통해 데이터전송을 하는 기법을 제안하고자 한다. 제안한 기법을 적용함으로써 노드에 대한 신고가 있을 때 확인과정을 거쳐 불필요하게 경로를 재탐색하는 과정을 줄일 수 있다.

The purpose of this study is to analyze the changes in trade and industry of Korea and suggest implications from the perspective of global value chains following the spread of COVID-19. To this end, products for prevention of epidemics which is directly related to COVID-19 and IT industries with high GVC participation were analyzed. Due to the spread of COVID-19, the variation in import and export of products for prevention of epidemics was large. In the case of masks, import and export of final goods changed drastically, but the change in intermediate goods was not significant relatively. Korea's IT industry has been differentiated according to major trading partners amid overall changes in GVCs which is summarized as higher forward participation and lower backward participation. While no particular change resulted from COVID-19 has yet been made directly, the need for diversification strategies should be taken into account at a time when the production links with China and Vietnam are close and the dependence on trade with these countries is high. The COVID-19 is still in progress, requiring corporate strategies and policy efforts to respond to changes in GVCs in the post-COVID-19 era.

Despite the recent social interest, academic discussions about life culture festival in Korea are still not actively discussed. Therefore, on this study we intends to conduct an empirical analysis on the satisfaction, loyalty, and effects of life culture festival by using structural equation model. Before the analysis, we reviewed conceptual definitions about life culture and its previous studies for set up detailed factors to be used for. This study is based on the survey which distributed in 2016 Bucheon City life culture festival "DaRak". With collected survey, we analyzed data by using structural equation model. As a results, festival loyalty shows significant impact on festival effects(0.92). Both program factor(0.59) and operation-information factor(0.29) also shows significant result about festival effects as lower factor of festival satisfaction, but its only when they mediated by festival loyalty factor.

The purpose of this study was to examine the relationship between parental participation motivation, satisfaction, and intention to reuse children with developmental disabilities using psychomotor centers. To this end, a questionnaire survey was conducted on the parents of children participating in psycho-exercise programs at a private developmental disability center located in the metropolitan area. The collected data was 188 copies, and the causal relationship was verified through descriptive statistics, factor analysis and reliability analysis, correlation analysis and regression analysis. As a result of the analysis, the following conclusions were obtained. First, in the relationship between parental participation motivation and satisfaction with regard to psychological exercise participation of children with developmental disabilities, only pleasure and social factors were significant in use satisfaction, and only social, health and physical fitness factors in performance satisfaction showed a significant influence. Second, in the relationship between participation motivation and intention to reuse, there were significant influences on pleasure, skill development and sense of achievement, and social factors. Third, in the relationship between satisfaction and intention to reuse, intention to reuse was significantly explained in factors of satisfaction with use and satisfaction with performance. In order to increase the reuse rate of psychomotor centers in the future, it is judged that additional analysis is necessary in addition to the measurement variables of this study.
