This study verified the moderating effect of brand familiarity and openness in the relationship between micro and macro-national image in Chinese market and brand attitude. The research methods used in this study based on previous studies, a research model was established, related research hypotheses were set up, and Chinese consumers were selected as survey subjects to conduct surveys and data collection, and the suitability test and research hypothesis of the model were verified. As a result of this study, Micro and macro-national image had a positive effect on brand attitude, brand familiarity and openness had no moderating effect on micro-national image, and macro-national image had a moderating effect on macro-economic image. The results of this study provide implications for companies in Korea, the United States, and Japan, which have close relations with China in the Chinese market, to utilize various business strategies.

Handover is needed in multi-hop relay systems to support mobility. The main purpose of handover is to provide the continuous connection when a MS migrates from the air-interface of one BS to another air-interface provided by another BS. Especially the handover between different systems is essential to next generation network. Vertical Handover technology in Mobile WiMAX MMR system is very useful for operators to introduce to Mobile WiMAX system in an overlaid cell environment. This technology will be applied to technology which hands MRS(Mobile Relay Station) over to different systems for system performance enhancement in Ubiquitous environment overlaid between Micro ce11(Frequency 1,FA1) and Macro cell(Frequency 2,FA2). In this paper, FA1 and FA2 are used in order to perform Vertical Handover of MRS(Mobile Relay Station) according to suggested conditions. interferences from neighboring BS or other sectors of 6 macro cells surrounding center Macro cell are analyzed and throughputs are measured according to suggested conditions.

The purpose of this study is to verify the effect of parent's support on the school adaptation of immigrant adolescents to school life, the mediating effect of self-esteem, and the moderating effect of cultural adaptation stress. The data used for the analysis were the second panel data (2020) among the multicultural youth panel survey data. As for the data analysis method, frequency analysis, descriptive statistics analysis, correlation analysis, PROCESS MACRO Model Number 4 and PROCESS MACRO Model Number 1 analysis were performed. As a result of the analysis, first, parental support showed a positive (+) effect on school life adaptation. Second, in the relationship between parent's support and school adaptation, self-esteem had a statistically significant indirect effect. Third, it was found that cultural adaptation stress had no moderating effect in the relationship between parent's support and school adaptation. Based on these results, policy and practical suggestions for improving the school adaptation of immigrant adolescents to school life were presented.

In this paper, we analyze the outage probability of macro diversity combining in cellular networks in consideration of aggregate interference from other mobile stations (MSs). Different from existing works analyzing the outage probability of macro diversity combining, we focus on a diversity gain attained by selecting a base station (BS) subject to relatively low aggregate interference. In our model, MSs are randomly located according to a Poisson point process. The outage probability is analyzed by approximating the multivariate distribution of aggregate interferences on multiple BSs by a multivariate lognormal distribution.

본 연구는 일과 삶의 균형(WLB : Work-Life Balance)이 대인 조화와 창의적 노력 및 조직 내 혁신 행동을 향상시키는지 여부, 그리고 대인 조화와 창의적 노력이 일과 삶의 균형(WLB)과 혁신 행동 간 관계에 간접 효과가 있는지 여부를 알아보기 위해 수행되었다. 본 연구의 가설 검증을 위해서는 Hayes(2013)의 PROCESS Macro를 활용하였다. 분석 결과 혁신 행동에 영향을 주는 것은 일과 성장의 균형(WLB_G)과 대인 조화 그리고 창의적 노력으로 나타났고 대인 조화에 영향을 주는 변수는 일과 가정의 균형(WLB_F)과 일과 성장의 균형(WLB_G)으로 나타났다. 또한 창의적 노력에 영향을 미치는 변수는 일과 성장의 균형(WLB_G)과 대인 조화였다. WLB의 세 개 하위 변수와 혁신 행동 사이의 관계에서 대인 조화와 창의적 노력의 간접 효과 역시 일부 확인 되었다. 더불어 PROCESS Macro 분석을 통하여 매개변수 간의 효과의 크기를 알아보았다. 이를 통해 일과 가정의 균형(WLB_F)이나 일과 성장의 균형(WLB_G)과 대인조화, 창의적 행동 및 혁신행동 간에는 시너지 관계가 존재하고, 일과 여가의 균형(WLB_L)과 대인조화, 창의적 노력 및 혁신행동 간에는 배타적 관계가 존재함을 알 수 있었다. 향후 다양한 다른 산업 간의 일과 삶의 균형(WLB)에 대한 연구와 일과 삶의 균형(WLB)과 혁신행동에 이르는 다양한 매개변수에 대한 연구가 기대된다.

In the macro/femto cellular networks, the portion of channels assigned to each cell is a critical factor which sets the stability and the performance of the whole system. To grasp the concrete influence that the channel split portion have on the system, we present the queueing model for IP based macro/femto cellular networks, and find the stability conditions. Additionally we provide the strategy to decide the portion of channels allocated to each cell. Through the experiments, we prove that the proposed strategies operate feasibly in various network environments, and on the basis of these results we discuss the efficient system structure plan.

본 논문에서는 상호 연결망의 노드를 행렬로 표현하고 행렬연산을 이용하여 에지를 정의한 새로운 상호 연결망으로 행렬-스타 그래프를 제안한다. 행렬-스타 그래프는 널리 알려진 스타 그래프를 일반화한 그래프이다. 먼저, 행렬-스타 그래프의 노드를 2 $\times$ n 행렬로 표현한 행렬-스타 그래프 MS2,n 에 대하여 주요 망 척도인 분지수, 연결도, 확장성, 대칭성, 리우팅 ,지름 방송등을 분석한다. 다음으로, 행렬-스타 그래프 MS2,n의 노드를 2차원과 3차원으로 일반화한 행렬-스타 그래크 MSk,n과 MS k,n,p를 정의하고 행렬-스타그래프 MSk,n,p 의 라우팅 알고리즘과 지름을 분석한다. 상호연결망의 중요 망 척도중 하나는 망 비용이고 상호연결망의 망 비용은 그 연결망의 분지수와 지름의 곱으로 정의된다. star 그래프는 다른 상호 연결망보다 작은 망 비용을 갖는다. 최근에 제안된 Macro-Star 그래픈 star 그래프에 비해 상대적으로 망 비용이 작은 값을 갖는 연결망이다. (n2)!개의 노드를 갖는 행렬-스타 그래프 MSk,k,k(k={{{{ `^{ 3} SQRT { n$^2$} }}}} )와 ((n-1)2 + 1)!개의 노드를 갖는 Macro-Star 그래프 MS(n-1, n-1)의 망 비용은 행렬-스타그래프 MSk,k,k(k={{{{ `^{ 3} SQRT { n$^2$} }}}})는 O(n2,7)이고, Macro-Star 그래프 MS(n-1 , n-1)은 O(n3) 이다. 이는 행렬-스타 그래프가 스타 그래프와 Macro-Star 그래프보다 망비용이 우수함을 의미한다.

This study is to validate the use of macro language for the land suitability analysis aiming to help to resolve land use conflicts. The silver-town suitability analysis is conducted on the Geejang Gun, Busan Metropolitan city. Such digital maps as terrain, road, facility, and water body were created for various cartographic models. A cartographic model identified the best suitable areas for silver-town development based on the such site selection variables as a distance to facility and road, slope and aspect of terrain, land use etc. Then, the other cartographic model identified the most favorable site among the candidate sites based on the comparison of the aspect of proximity, usage and environmental quality. Macro language was used for these modeling process and was used for the manipulation of all these spatial variables used in the models to resolve land use conflicts relating to the decision making process of the final site selection. This study will improve the effectiveness and rationality of the traditional site suitability analysis.

Massive civic protests and consequent presidential impeachment requires a serious revisiting to democratic theories of Korean democracy. This paper explores the strengths and limitations of macro and micro approaches. Changes in democratic realities was manifested on three fronts. First, the rise of new political subject, that is, participants to massive protest. Second, changing nexus between representative institutions and civic protests. Third, parliamentarization of presidential democracy. Specifically macro approach has changed its negative assessment of democracy into positive evaluation. Macro theory has to revisit it's notion of 'minjung' to cope with the rise of new subject. Also macro approach has to struggle with the declining role of civic organizations and political activists. Micro approach has to deal with new mode of networking among citizens and to unravel the evolving relation between democratic institutions and civic protests. In sum, theories need to expand the analytic scope, to revitalize analytic tools and to rebalance value judgment and analytical efforts.
