This study was designed to examine the relationships between rough and tumble play and children's social language use. The subjects were 90 children in a nursery school in N city. The data was analyzed using the Pearson correlation and stepwise regression. The results were as follows. First, there was a significant positive relationship between rough and tumble play, and the children's social language use. Second, the children's social language use' sub valuables had an effect on rough and tumble play. In particular, 'demand of action' has negative effects on the 'pull and push', and 'catch'. Furthermore, 'rejection' has negative effects on 'collapse' and 'rush'. This suggests that a rough and tumble play program can be developed to enhance the children's social language use.

본 논문에서는 유 무선 네트워크 환경에서의 자료 일치성 유지를 위한 동기화 프로토콜(SyncML1.1)을 검증한다. 프로토콜 검증에 관한 기존 연구에서는 약한 일관성을 갖는 동기화 프로토콜은 다루어지지 않았으며 정리 증명 혹은 모델 채킹에 대한 선택적 접근으로인해 증명 영역이 제한적이었다. 본 연구에서는 프로토콜의 의미를 정의하고 행위 및 시스템 구조, 메시지 패싱에 대한 개별적 모델을 단계적으로 설계하는 한편, 동기화 프로토콜에서의 안전성 및 상호 배제, 궁극성 속성은 시퀀트 계산법에서의 역방향 전략으로 증명되며, 모델 채킹 기술을 하나의 증명 규칙으로 사용했다. 본 연구는 두가지 부분에서 특징과 의미을 갖는다. 첫째, 정리증명과 모델 채킹이 혼합된 검증 방법을 사용했다. 둘째, 객체 제약 언어 및 정형 명세 언어의 사용을 통해 모델의 생성을 보다 단계적이고 정형적으로 유도했으며 이를 통해 검증의 신뢰성 및 품질을 높였다.

This study aims at empirically analyzing the overall mechanism of the "Gray Zone Strategy", which has begun to be used as one of Chinese major maritime security strategies in maritime conflicts surrounding the South China Sea and East China Sea since early 2010, and comparing the resulting conflict patterns in those reg ions. To this end, I made the following two hypotheses about Chinese gray zone strategy. The hypotheses that I have argued in this study are the first, "The marine gray zone strategy used by China shows different structures of implementation in the South China Sea and the East China Sea, which are major conflict areas.", the second, "Therefore, the patterns of disputes in the South China Sea and the East China Sea also show a difference." In order to examine this, I will classify Chinese gray zone strategy mechanisms multi-dimensionally in large order, 1) conflict trends and frequency of strategy execution, 2) types and strengths of strategy, 3) actors of strategy execution, and 4) response methods of counterparts. So, I tried to collect data related to this based on quantitative modeling to test these. After that, about 10 years of data pertaining to this topic were processed, and a research model was designed with a new categorization and operational definition of gray zone strategies. Based on this, I was able to successfully test all the hypotheses by successfully comparing the comprehensive mechanisms of the gray zone strategy used by China and the conflict patterns between the South China Sea and the East China Sea. In the conclusion, the verified results were rementioned with emphasizing the need to overcome the security vulnerabilities in East Asia that could be caused by China's marine gray zone strategy. This study, which has never been attempted so far, is of great significance in that it clarified the intrinsic structure in which China's gray zone strategy was implemented using empirical case studies, and the correlation between this and maritime conflict patterns was investigated.

Despite various policies have been implemented to curb shadow education in Korea, it has continued to grow in recent two decades. This study investigates the expansion mechanism of shadow education focused on mobilization capabilities and market strategies of the suppliers. The success and failure of policy toward shadow education depends on how effectively it could block off the way by which the suppliers as the most important actors in politics of shadow education market mobilize consumers' anxieties. But shadow education policies have failed in two points. First, they have lacked honest intention to stop its proliferation. The Constitutional Court Decision Against Anti-Out-Of-School Classes Legislation of 2000 widened the windows of opportunity for the suppliers, and 5.31 educational reform of 1995 was neutral to their mobilization capabilities, though seemingly designed to control shadow education. This policy orientation, which reflected neoliberal Gesinnungsethik defective of Verantwortungsethik, stimulated shadow education to expand in that suppliers' mobilization capabilities were reinforced or remained intact. Second, shadow education suppliers have succeeded in mobilizing the desire and anxiety of potential consumers. To cope with government's policy including improving the qualities of public education, realignment of college entrance systems, and meeting the shadow education needs, they have developed various market strategies such as management of existing demands, creation of responsive demands, and squeezing out new demands. They have succeeded in nullifying policies by employing or mixing strategies with effect. Policy decisions in the future need to be made with reference to Verantwortungsethik, and be more cautious to socio-political contexts of Korea, to mobilization capabilities and market strategies of the suppliers in particular.

This study interpreted film-creators' information behavior by reconstructing information behavior in the process of film-planning using human information behavior. Film creators exchange, collect, and analyze information through channels in the information environment so called "the small world." After these processes, they strategically express this information by creating a film. This study concludes that the purpose of film-creating activity and that of everyday life information seeking are intertwined and that co-communication is the most important information channel and information source.

Many organizations have had deep interests in studies concerning leadership and also in academic area, not only management but also psychology. Until now, the leadership has been accentuated to managers or team leaders especially. Recently, however, the concept of self-leadership that lead one's own activities toward right direction through self-control or self-management is being focused on practices and academia. This study is to investigate the influence between self-leadership strategies and learning performance at IT classes mediated by attitude of attendance focused on the social science students in an university. Research results can give us right direction of task-taking attitudes in firms or learning attitudes in teaching organization and implications to human resource manager who are in charge of improving learning performance or productivity.

Since the 1990s, political geographers have focused on the study of the process of border construction. They have shifted from the old morphological and functional approaches to boundary that have focused on the types and functions of boundaries. Recent scholarship on border studies understand boundaries and the border regions as entities with overlapping and competing relationships not as manifestation of territoriality. There has been the emphasis on the multidimensional actors and the historical and cultural legacies inherent in the border region as well. Based on these recent discussions, this study examines how the border region has been constructed by various actors and strategies in Dandong China, the border city between North Korea and China. Several sanctions including UN Security Council have been resolved and implemented in accordance with North Korea's nuclear and missile development, which is a relevant example to examine the "border as relationships" in which strategies of various actors are competing. In addition, this paper has a significance as a case study on the construction process of border and the characteristics of its materiality, which is a way to overcome the limitation of discourse-oriented critical geopolitical research.

In this paper, the method of analyzing the unformatted data of consumers accumulated on social networks in the era of the Fourth Industrial Revolution by utilizing data from the service design and social psychology aspects was proposed. First, the fandom phenomenon, which shows subjective and collective behavior in a space on a social network rather than physical space, was defined from a data service perspective. The fandom model has been transformed into a collective level of customer Persona that has been analyzed at a personal level in traditional service design, and social network analysis that analyzes consumers' big data has been presented as an efficient way to pattern and visually analyze it. Consumer data collected through social leasing were pre-processed by column based on correlation, stability, missing, and ID-ness. Based on the above data, the company's brand strategy was divided into active and passive interventions and the effect of this strategic attitude on the growth direction of the consumer's fandom community was analyzed. To this end, the fandom model of consumers was proposed by dividing it into four strategies that the brand strategy had: stand-alone, decentralized, integrated and centralized, and the fandom shape of consumers was proposed as a growth model analysis technique that analyzes changes over time.

지능형 지속 위협(Advanced Persistent Threat) 공격은 Intrusion Kill Chain과 같은 일련의 단계로 구성되어 있기 때문에 특정 단계가 차단되면 공격은 실패하게 된다. Moving Target Defense(MTD)는 보호대상의 주요 속성(네트워크, 운영체제, 소프트웨어, 데이터)을 변화시켜 Intrusion Kill Chain을 구성하는 각 단계를 차단하는 능동적 사전 보안 기술이다. MTD 전략 중에서 네트워크 주소 변이(Network Address Mutation) 기술은 보호대상의 네트워크 주소(IP. Port)를 능동적으로 변이하는 기술로써, Intrusion Kill Chain의 첫 단계인 정찰(Reconnaissance) 행위에 소요되는 비용을 급격하게 증가시킬 수 있는 효율적인 보안 기술이다. 본 논문은 네트워크 주소 변이 기술 분야의 관련 연구들을 살펴보고 네트워크 주소 변이 기술 설계 시 고려해야하는 보안 요구사항과 기능 요구사항을 제안한다.
