본 연구는 국내의 4개의 주요한 패밀리레스토랑를 이용한 경험이 있는 고객을 대상으로 방문횟수에 따른 수요 결정요인과 레스토랑 간 대체성을 살펴보고자 하였다. 방문 수요 결정요인으로는 인구통계적 특성, 패밀리레스토랑 브랜드 이미지, 레스토랑 이용횟수의 비율에 따라 유의적인 영향관계를 보이고 있으며 또한 편상관분석을 통한 경쟁관계의 레스토랑의 대체성을 확인하였다. 이러한 결과는 레스토랑 방문횟수에 영향을 주는 결정요인을 파악함으로서 레스토랑의 마케팅방향을 설정하고 경쟁 레스토랑 간의 경쟁관계를 살펴봄으로서 레스토랑의 경쟁력을 키울 수 있는 계기를 마련하는데 도움을 줄 수 있다.

In this paper, we propose signaling procedures amon network elements for a connection rerouting method which can reduce inter-switch handoff processing delay reduces the delay in the connection re-routing by reserving VPI/VCIs for possible inter-switch handoff calls in advance. Additionally, we mathematically analyze the signaling procedures and then suggest solutions to the relations with cluser size, network topoloty, handoff-request rete and handoff delay. With simulation, the solutions are validated. From numerical examples, we concluded taht handoff delay, one of the handoff QoSs, can be satisfied by adjusting the cluster size and network topology according to the handoff -request rate of service area. With our proposed signaling and analytic methods, we concluded that the connection rerouting method using cluster-sectoring effectively reduces the delay of inter-switch handoff processing than dynamic connection rerouting method. Our solutions are useful in guaranteeing the requested handoff delay (especially, inter-switch handoff delay) when the connection rerouting method is applied to ATM-based wireless/wired integrated network.

The purpose of this study was to investigate the mediating effects of inter-organizational relation on the relation between resilience and school adjustment in elementary school students. The results of this study are as follows: First, there were positive relations among student's resilience, school adjustment, and inter-organizational relation. Second, the mediating effect of inter-organizational relation in the relation between student's resilience and school adjustment was shown by the partial mediating effect. The result of the study shows that student's resilience is the variables influencing school adjustment. Therefore, it suggests to establish inter-organizational relation, ethical climate for active communication among school members in order to improve student's school adjustment. Based on the results, findings and implications are discussed.

The purpose of this paper is to confirm the trend of inland water fish farming in North Korea and to suggest a plan for inter-Korean cooperation. North Korea's inland water fish farming laid the foundation for production in the 1950s and 1960s, and production facilities were expanded until 1980. In the midst of the severe economic crisis in the 1990s, North Korea paid attention to inland water fish farming as an alternative to food production. The military took the lead in expanding the aquaculture industry and catfish farming was encouraged. In the Kim Jong-un era, North Korea's inland fish farming continues the tradition of catfish farming and promotes a policy of expanding inland cage farming. This study comprehensively reviewed recent inter-Korean relations, North Korea's food crisis and acceptability, and UN sanctions. As a result, inland water fish farming is the most promising field for inter-Korean cooperation in the field of fisheries. In the initial stage of inter-Korean cooperation in the field of inland water fish farming, humanitarian aid projects such as feed and seed support can be promoted. In the stage of expanding inter-Korean cooperation, knowledge sharing program and materials and facilities support projects can be promoted. Development cooperation and direct private investment are possible at the full-scale stage.

Members of the ciliate group of protozoans are often observed in mass cultures of rotifers. In particular, Euplotes and Vorticella are common contaminating species. In this study, I examined the effect of the ciliates Euplotes sp. and Vorticella sp. on the growth of the rotifer Brachionus rotundiformis by conducting inter-specific and tripartite-specific mixed-culture experiments. The growth of rotifers was suppressed in co-existence with Euplotes sp. compared with monocultures of rotifers. However, Vorticella sp. promoted rotifer growth. Moreover, Vorticella sp. improved the growth of rotifers suppressed by Euplotes sp. contaminants. In 5-L semi-mass cultures of rotifers, growth of the contaminating protozoan Euplotes sp. was heavily suppressed by Vorticella sp. The stable maintenance of the rotifer culture ecosystem can be achieved by manipulating the types of contaminating protozoan species.

기술표준화에 영향을 미치는 제도적 요인으로서 국가개입 수준, 기업관계를 제시하고 이를 통합하여 국가마다 상이한 기술표준화 과정을 설명하는 틀을 구성하였다. 이러한 분석틀을 이동통신산업에 적용한 결과, 혁신체제에 따라 기술표준화의 방식도 상이하다는 점을 확인하였다. 단절적 기업관계의 체제에서는 기술표준화가 시장을 통해 이루어지는 반면 협력적 기업관계의 체제에서는 기업연합의 조정활동을 통해 이루어진다. 한편 국가주도적 체제 내에서도 기업관계가 단절적인 체제에서는 상대적으로 국가가 기술표준화 과정에 더욱 깊숙이 개입하고 기업관계가 단기적인 반면, 기업관계가 협력적인 체제에서는 기업관계가 장기적이다.

Former South Korean President Moon Jae-in implemented a project called the Peace Initiative, which prioritized a "peaceful and prosperous Korean Peninsula" as the core national agenda and involved using a peace-based frame instead of a unification approach to address inter-Korean relations from a different perspective. This initiative was evaluated in this study using a revised version of the pyramid model to assess the input-output-result process underlying the project and determine whether it generated results that differed from those achieved by the previous administration. To these ends, this research compared Moon's key presidential speeches with those of his predecessor, Park Geun-hye, as input, news commentaries and responses from major players as output, and the trend of perceptional and attitudinal changes in public opinion as results. Although Moon failed to accomplish significant policy effects on inter-Korean relations because of geopolitical challenges and the transfer of power to the conservative party, the analysis revealed that the input, output, and partial results of inter-Korean dialogue reflect some progress.

Communication in delay tolerant networks (DTNs) relies on message transport by mobile nodes, and a correct understanding of the node mobility characteristics is therefore crucial to the design of an efficient DTN routing protocol. However, previous work has mainly focused on uncovering all behaviors of node movement, which is not conducive to accurately detecting the specific movement characteristics of a different node. In this paper, we seek to address this problem based on a consideration of social relationships. We first consider social ties from both static and dynamic perspectives. For a static perspective, in addition to certain accidental events, social relations are considered for a long time granularity and tend to be stable over time. For a dynamic perspective, social relations are analyzed in a relatively short time granularity and are likely to change over time. Based on these perspectives, we adopted different efficient approaches to dividing node pairs into two classes, i.e., familiar and unfamiliar pairs. A threshold approach is used for static social ties whereas a density-based aggregation method is used for dynamic social relationships. Extensive experimental results show that both familiar and unfamiliar node pairs have the same inter-contact time distribution, which closely follows a power-law decay up to a certain point, beyond which it begins to exponentially decay. The results also demonstrate that the inter-contact time distribution of familiar pairs decays faster than that of unfamiliar pairs, whether from a static or dynamic perspective. In addition, we also analyze the reason for the difference between the inter-contact time distributions of both unfamiliar and familiar pairs.

3차 남북 정상회담과 평양 남북정상회담, 싱가폴과 하노이에서 열린 북미 정상회담 이후, 한반도의 운명을 좌우할 비핵화 협상이 진행되고 있다. 하지만 비핵화 조건을 둘러싸고 북미간 입장이 충돌하며 협상은 교착국면에 빠져있으며 다소 회의적인 전망이 예견되고 있는 상황이다. 북한의 완전한 비핵화 실현이 어려운 이유는 동북아의 전통적인 안보딜레마와 미중간 패권경쟁, 신냉전체제의 형성 등 다양한 변수들이 상존하기 때문이다. 지난 2018년 평창 동계올림픽을 계기로 3차례의 남북 정상회담과 3차례의 북미 정상회담이 개최된 전환기적 시점에 북한의 완전한 비핵화는 한반도를 넘어 동북아와 세계평화를 위해 반드시 이루어내야 할 역사적 과제가 되었다. 그런 의미에서 평양 남북정상회담은 '9.19 평양공동선언'과 '군사분야 합의서'를 통해 북한비핵화와 남북관계 발전을 위한 새로운 이정표를 제시해 준 역사적 계기로 평가된다. 한편 국제정치이론의 주요 패러다임으로 자리잡은 구성주의(Constructivism)는 이념과 역사, 문화 등의 관념적 변수가 물질적 요인, 국가행위자의 정체성과 이익을 규정하며 국제관계의 구조가 상호작용을 통해 변화될 수 있다는 관점을 제시한다. 본 연구에서는 이제 1주년을 넘긴 9.19 평양공동선언의 역사적 의미를 구성주의적 관점에서 고찰하였다. 이를 위해 구성주의 이론의 발전과정과 분석모델, 남북관계의 발전과정을 간략히 살펴보았고, 9.19 군사합의서의 군사적 함의를 제시하였다.

본 연구에서는 재난구호 관련 법령분석, 재난구호체계 분석, 주요 재난구호 사례분석을 통해 재난구호체계에서의 정부간 관계를 규명하였다. 분석 결과, 중앙정부가 지방정부의 재난구호활동을 총괄 조정하며, 행정 및 재정상의 지원을 통해 관리감독하고 있는 것으로 나타났으나, 재난구호활동에 있어 지방정부에게 행정적 재정적인 부담을 가중시키고 있는 것으로 나타났다. 또한 재난관련 법령 상 구호물자 전달에 대한 구호기관 및 구호지원기관 간 역할분담이 구체적으로 명시되어 있지 않으며, 구호물품 전달 상황에 대한 상호간 정보교류가 없어 중복지급으로 인한 비효율성 및 자원낭비를 초래하고 있는 것으로 나타났다.
