This paper is concerned with the query slipping and its prevention for trajectory-based matchmaking service in wireless sensor networks. The problem happens when a query propagating along a subscribe trajectory moves through a publish trajectory without obtaining desired information, even though two trajectories intersect geometrically. There follows resubmission of the query or initiation of another subscribe trajectory Thus, query slipping results in considerable time delay and in the worst, looping in the trajectory or query flooding the network. We address the problem formally and suggest a solution. First, the area where nodes are distributed is logically partitioned into smaller grids, and a grid-based multicast next-hop selection algorithm is proposed. Our algorithm not only attempts to make the trajectory straight but also considers the nodal density of recipient nodes and the seamless grid-by-grid multicast. We prove that the publishing and subscribing using the algorithm eventually eliminate the possibility of the slipping. It toms out that our algorithm dissipates significantly less power of neighbor nodes, compared to the non grid-based method, as greedy forwarding, and the fixed- sized grid approach, as GAF (Geographical Adaptive Fidelity)

The purpose of this study was to find out correlation and predictors of posttraumatic growth of North Korean refugees in South Korea in 7years. This survey was conducted on 105 North Korean refugees in 7 years with questions on socio-demographic characteristics, personal & social variables, psychological trauma in North Korea and stress experience in South Korea. The influence of these variables was analysed. Result indicated that hope for future, perceived satisfaction, and acculturative stress had influence on the total quality of life in the South. And total quality of life affected PTG, especially emotional factors of quality of life during the early 3years living in the South affected PTG.. Additionally not only emotional but also social factors of quality of life also affected PTG with North Korean refugees in the South in 7 years.

본 연구는 북한이탈주민의 경제적 자립과 안정적인 정착을 지원하는 하나의 방안으로서 창업을 촉진하기 위한 지원 정책과 제도 개선 방안을 제시할 목적으로 수행하였다. 정부는 현재 생활밀착형 북한이탈주민 정책 추진 기조하에 북한이탈주민의 삶의 질을 높여주는 방향으로 맞춤형 정책을 추진하고 있다. 다만, 창업지원 프로그램은 여전히 소규모로서 지원 분야를 다양화하고 예산을 증액 하는 한편, 지원 체계도 중앙-지방-민간 간 유기적으로 협업이 효율적으로 이루어지도록 개선이 필요하다. 본 연구는 북한이탈주민의 창업의지 결정요인에 대한 실증적 연구를 목적으로 하며, 북한이탈주민들에게 잔존하는 사회주의 가치체계와 이들의 사회적응성 요인을 기존 연구에서 확인되었던 개인의 성격적 특성, 경제적 지지, 자아성취욕구 요인들과 함께 분석모형에 포함하여 실증 연구를 수행하였다. 이를 위해 하나원에서 교육 중인 18세 이상 북한이탈주민 223명을 대상으로 2019년 10월 설문조사를 통해 자료를 수집하였고, 선형회귀분석과 이분형 로지스틱 모형분석을 이용하여 실증분석을 수행하였다. 2개의 분석 모형에서 일관된 결과가 도출됨에 따라 분석결과의 강건성을 확인하였다. 결과적으로 사회주의 가치체계가 약할수록 창업의지에 긍정적인 영향을 미칠것이라는 가설은 지지되었다.

To examine the process of spermiogenesis in the Korean red-backed vole, Clethrionomys rufocanus regulus, the seminiferous epithelium in the testis, was studied by trasmission electron microscopy, and the following results were obtained based on the morphological characteristics of cell differentiation. 1. According to the fine structural differentiation, spermiogenesis was divided into Golgi, cap, acrosome, maturation and spermiation phases. Besides, these phases were sub-divided into two steps : early and late phases respectively, Thus, the spermiogenesis of Clethrionomys rufocanus regulus was divided into a total of ten steps. 2. In the changes of the chromatin, the chromatin granules began to be condenced in the late Golgi phase, regularizated at maturation phases, and a perfect nucleus of sperm was formed at the spermiation phases. 3. The sperm head had the falciform, and the formative period of sperm tail began to be develop in the early Golgi phase and completed at the spermiation phases. 4. In the morphological features of spermiation phases, the spermatid of early spermiation phase was divided into three types : (1) A-type spermatid contained cytoplasmic droplets in the neck region and middle piece, and the mitochondria was irregular, and arranged around the axoneme. (2) B-type contained cytoplasmic droplet in the middle piece only, and the mitochondria are arranged the center of axoneme regularly, and (3) In the C-type spermatid, the arrangement of mitochondria was regular, and was contained cytoplasmic droplet in the neck region only. In the late spermiation phase, only the sperm head was surrounded by cytoplasm of Sertoli cell or the matured sperm just before the spermiation from the cytoplasm of Sertoli cell.

This research investigates the influence of relational characteristics on 'co-defection', customer defection following salesperson turnover, in the context of salesperson-customer relationship. Based on the social exchange theory, it was hypothesized that perceived relational benefits and switching costs affect directly the customer's intentions to defect. Key constructs in relationship marketing such as customer satisfaction, trust, and loyalty were hypothesized to affect the customer's intention to defect as well as perceived relational benefits and switching costs. The results of structural equation modeling using a survey sample of 503 insurance customers who purchased life insurance policies through salespersons unveiled that the customer satisfaction with salesperson and the customer trust in salesperson strongly influence the salesperson-owned customer loyalty. However, they did not have significant direct effects on co-defection intentions. All paths from salesperson-owned customer loyalty to perceived relational benefits and perceived switching costs were also significant. Salesperson-owned customer loyalty did not have significant direct effects on co-defection intentions, but it had significant indirect effects on co-defection intentions through relational benefits and switching costs. Three sub-dimensions of perceived relational benefits had significant positive effects on co-defection intentions while the perceived switching costs had significant negative effects on co-defection intentions. The significance of our research findings were verified by comparing the hypothesized model and the rival model in the past studies.

This paper aims to analyze how the Venture Business Tendency of North Korean refugees affects social adaptation and family health, and to provide proposals for policy making on the issue. For the purpose, we specifically suggest analysis of activation plan that 48 Venture Business North Korean managed Enterprise types, Entrepreneur type, Business type, Gender, Profit etc. As a result of analysis of actual proof, First, The Venture Business North Korean refugees managed need to consult to be technology business professionally because they features to be self-employment than expertise and knowledge basis type. Second, the rate of success of North Korean refugees is researched that female is higher than male. Third, to support Venture Business of North Korean refugees, they need one on one incubating support syspen why they are inexperienced in network, technical skills. Fourth, Venture Business Tendency of North Korean refugees affects social adaptation and family health. Since mid 1990's, North Korean refugees have come to South Korea through China or third countries due to collapsing economy of North Korea. In an effort to help those escaping from North Korea, the Seoul government provided them with a 3-month settlement program. But they have had experienced difficulties in communication, cultural assimilation, and confusion in their value system and identity. For the purpose, one-on-one interview was carried out on 45 North Korean refugees living in Seoul and neighboring cities, and the interviewed group was classified into three categories: single households, single-parent families and families with parents. The study findings demonstrated four policy alternatives to help improve quality of life of North Korean refugees and to help their successful settlemen.

Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects. A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major age-based categories. 'Balance', 'Diversity', 'Moderation', and 'Dietary behavior' were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants' age groups were stratified by 20's, 30's, 40', and over 50's. A χ² test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20's age group were less likely to report the total NQ and moderation score than the 50's age group. Conclusion: In this study, the 20's age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.
