The purpose of this study was to establish strategies that support multi-cultural children' development and adaptation in day care centers. The subjects were 61 young children, 49 parents from multi-cultural family and 550 Korean young children. The instruments utilized were the Sukemune-Hiew Resilience Test for parents and the Danaka Deveopment Test for children. The statistical instruments used were the t-test and the Pearson product correlation coefficients. Our results indicated that : (1) In the case five or six years old children from multi-cultural families, language development lagged behind that of Korean children. (2) Social support systems were insufficient for parents of multi-cultural families. Our cnclusions suggest that establishing strategies is necessary for not only supporting the linguistic development of children from multi-cultural families, but strategies aimed at supporting their parents in day care centers need to be developed.

The study was done to provide domestic fashion multi-shops with basic Information about the distribution and the promotion strategies through an investigation the marketing strategies for domestic multi-shop dealt with imported product only. Data were collected from Interview with a buyer or a staff of marketing department of Domestic Fashion Multi-shop dealt with Imported Product only. The results were as follows： For the distribution strategies, these fashion multi-shops as chosen were all placed in department stores. Their distribution channels were diverse like road shop, shop in department store and shop under direct management of department store. In case of shop in department store, it was common that the shop paid a definite commission to the department store. But S shop was managed directly by a department store as an advanced buying system that department store bought and sold goods and held themselves responsible for overstock. For the promotion strategies, these fashion multi-shops didn't make a definite budget for advertising and publicity contrary to other one-brands. But they attached importance to visual merchandising (VMD) because they had to harmonized the concept of a shop with various brands. Also they concentrated on seasonal fashion show, management of their customers and personal sales.

Purpose: This descriptive study aims to analyze the effects of the satisfaction level in the relationship between mother-in-law and daughter-in-law, conflicts between them, acculturative stress and stress coping strategies on elderly depression in multi-cultural families. Methods: The survey was conducted on 89 mothers-in-law, aged 65 or older, in multi-cultural families with a foreign daughter-in-law. Data were collected through structured questionnaires, and then were used to conduct t-test, ANOVA, correlation and multiple regression analyses using the statistical program SPSS 21.0. Results: This study found several factors contributing to depression of mothers-in-law in multi-cultural families. Those factors include living alone without a spouse, poor health, a high level of perceived discrimination and a passive reaction in terms of stress coping strategies. Conclusion: A sense of discrimination perceived by the mothers-in-law having a foreign daughter-in-law implies that the people around them and the community should make efforts to reject distorted perspectives and remove prejudice against foreign daughters-in-law. In addition, the mothers-in-law should receive education and training to use more active and positive stress coping strategies in a stressful situation with the foreign daughter-in-law.

본 연구의 목적은 일반적으로 공유되어 있지 않은 Multi Strategy 관련 금융투자 지식을 사례 연구를 통해 탐색하고 이를 국내 헤지 펀드 시장에 공유하는데 있다. 현재 국내에서 본격적인 사모 헤지펀드 시대가 열리면서 많은 펀드들이 만들어지고 있지만 전략의 다양성에 있어 부족한 것이 현실이다(이준서, 2016). 초기 단순한 Equity Long/Short 전략으로 시작되어 메자닌, 대체투자 등 여러 전략들이 활용되고 있지만 Multi Strategy를 활용한 펀드는 제한적인 상황이다. 본 연구에서는 증권사 Prop Trading에서 적극적으로 활용되고 있는 Multi Strategy 기법을 이용해 Absolute Return을 달성하는 과정과 결과에 대한 사례 분석을 바탕으로 헤지펀드 운용전략에 대한 실증적인 활용 방안을 제시하고자 한다. 본 연구의 결과를 통해 헤지펀드 시장에서 Multi Strategy를 활용해 Absolutr Return을 추구하고자 하는 연구자 및 실무에서 운용하는 펀드매니저가 지식을 탐색하고 공유해서 금융 경쟁력 강화를 도모하는데 기여하고자 한다.

This paper derives two main end-to-end performance metrics, namely the spatial capacity density and the average end-to-end delay of the multi-hop wireless ad hoc networks with multi-antenna communications. Based on the closed-form expressions of these performance metrics, three hopping strategies, i.e., the closest neighbor, the furthest neighbor and the randomly selected neighbor hopping strategies have been investigated. This formulation provides insights into the relations among node density, diversity gains, number of hops and some other network design parameters which jointly determine network performances, and a method of choosing the best hopping strategy which can be formulated from a network design perspective.

최근에 데이터베이스 응용분야에서 내용기반의 검색이 가능한 이미지 데이터와 같은 다차원 정보 처리에 대한 관심이 고조되고 있다. 따라서 다차원 데이터를 효율적으로 저장하고. 사용자가 원하는 질의 결과를 신속히 제공하는 것이 중요한 연구분야이다 다차원의 데이터에 대한 질의는 대표적으로 영역질의 (Range query)와 최근접객체검색질의(Nearest Neighbor Query)로 나눌 수 있다. 본 논문에서는 $R^*-tree$와 같은 다차원의 인덱싱 구조에서 효율적이고 빠른 k-근접객체검색질의를 수행하기 위한 방안을 제시한다. k-근접객체검색질의는 질의 객체로부터 가장 근접한 k개의 객체를 반환하는 것이다. 본 논문은 이를 위하여 가지치기(Pruning) 기법을 이용하여 검색 공간을 줄이는 방법을 사용하였다. 실험을 통하여 제안된 전략의 오버헤드와 이득을 보였으며, 마지막으로 가장 효율적인 전략의 사용을 제안하였다.

It has been realized that the design codes and underlying design concept of high seismicity region may not be appropriate to low and moderate seismicity regions. The aim of this paper is to search seismic design strategies that are appropriate to moderate seismicity regions. The characteristics of seismic hazard in moderate seismicity regions are reviewed. The seismic responses of multi-span continuous bridges subjected to the ground shaking of moderate intensity are examined. The present code on seismic design of bridges is briefly reviewed. Based on these observations, design principles and strategies appropriate to the moderate seismicity regions are proposed for the multi-span continuous bridge

This paper studies a novel method to find the profit-maximizing Nash Equilibriums in allocating generation quantities with consideration of ramp-rates under competitive market environment. Each GenCo in a market participates in a game to maximize its profit through competitions and play a game with bidding strategies. In order to find the Nash equilibriums it is necessary to search the feasible combinations of GenCos' strategies which satisfy every participant's profit and no one wants various constraints. During the procedure to find Nash equilibriums, the payoff matrix can be simplified as eliminating the dominated strategies. in each time interval. Because of the ramp-rate, generator's physically or technically limits to increase or decrease outputs in its range, it can restrict the number of bidding strategies of each generator at the next stage. So in this paper, we found the Nash Equilibriums for multi-stage generation allocation game considering the ramp-rate limits of generators. In the case studies, we analyzed the generation allocation game for a 12-hour multi-stage and compared it with the results of dynamic economic dispatch. Both of the two cases were considered generator's ramp-rate effects.
