Family-based tests such as the transmission and disequilibrium tests(TDT) have proved to be powerful tools in the search for disease genes. Unlike case-control studies, the tests are not affected by population admixture, which can lead to spurious association of multiple highly linked makers with disease-susceptible genes. Those tests have largely required knowledge of parental marker genotypes. However, parental data are often not available for late-onset diseases. In this article we propose sib-TDTs that overcome this problem by use of marker data from unaffected sib(s) instead of parents. To do this end, we fist defined a Mantel-Haenszel-type statistic for each haplotype and then proposed two tests based on this statistic. Simulation studies suggest that the proposed tests are robust to population admixture and are monotone increasing as a relative risk increases irrespective of mode of inheritance. We also illustrated the proposed tests with data adopted from Yonsei Cardiovascular Genome Center.

Objective: This study examined the role of siblings with respect to living arrangements between married children and their parents. Previous studies have rarely considered the possibility that family context such as siblings may be associated with intergenerational residential proximity. Method: Using data from first wave of the Korean Longitudinal Study of Ageing (2006), I investigated if, among married children, their sibling characteristics may be associated with the probability of their coresiding with the parent(s), living nearby (within a 30-minute distance from parent(s) by public transportation), or living further away. Specifically, the total numbers of sisters and brothers, the numbers of siblings coresiding with the parent(s) and living nearby, their relative position in the sibling network (first-born son, later-born son, first-born daughter, later-born daughter), and sibship existence and gender configurations (only child, son with brother(s) only, son with sister(s) only, son with both brother(s) and sister(s), daughter with brother(s) only, daughter with sister(s) only, daughter with both brother(s) and sister(s)) were evaluated in the study. For data analysis, multinomial logit models with robust standard errors were estimated using the Stata mlogit procedure. Results: Results suggest that the probability of a married child living together with the parent(s), relative to living close by, was significantly higher the more sisters he or she has. Being a son, especially first-born son, was associated with a higher probability of intergenerational coresidence compared to near residence, respectively. Also, the numbers of siblings coresiding with the parent(s) and living in close proximity were linked to a higher risk of intergenerational coresidence and near residence. Supplementary analyses revealed that the last finding was held over and above the total number of siblings, their relative position in the sibling network, as well as sibling existence and gender configurations. Conclusion: Overall, the study findings indicate that sibling characteristics have significant impacts on intergenerational living arrangement. The influence of traditional patrilineal norm of intergenerational coresidence and a trend towards modified extended family have emerged when siblings characteristics are taken into consideration as determinants of intergenerational living arrangement.

Purpose: This study is to understand how community members perceive past life recollection and preparation for death. Methods: Using a questionnaire, we surveyed 160 adult residents of one of the districts (gu) in Seoul, Korea. Descriptive statistics were used. Results: Participants chose their 30s and 40s as the most difficult time in their lives. The most painful experience was "an illness of a family member", followed by "trouble with a spouse", and "trouble with children". As for the most difficult social experience, "sense of loss in life" was ranked the highest. Personally, the happiest time was "accomplishment of a goal", while it was "happiness through children" in family relationship and "contribution to society through my career" in social life. As for the most regrettable experience, personally "having lived without purpose" was the highest, "not meeting my parents' expectation more" in family relationship; "not providing sufficient education" in relationship with children; "not having an occupation that I wanted" in work life, and "lack of social skills" in social life. More than 87% of the surveyed showed a positive attitude about the system of the do not resuscitate (DNS) order. For a situation where participants were supposed to have an incurable disease, "I want to be notified of the true condition" and "I want to write a will and advanced directives" ranked high, receiving more than 3.1 points out of 4. Conclusion: These results demonstrate the need for death education to provide people with an opportunity to accept their regrettable experiences in the past as part of their life. Also, this study suggests the importance of writing advanced directives for people to prepare for "death with dignity" how it can help their decision to be better respected.

The purpose of this study was to explore the different perceptions of relationship with significant others of multicultural children with PTSD symptoms. To select the subjects for this study, Korean version of Greenwald and Rubin's CROPS(Child Report of Post-traumatic Symptoms) was administered to 97 multicultural children and 110 Korean children. Among them 20 multicultural children and 22 Korean children were determined as children with PTSD symptoms. SCT was administrated to 42 children and the content analysis of 42 SCTs was undertaken. The following results are the major findings of this research: a) multicultural children perceived their mothers, fathers, friends, and teachers more negatively than Korean children; b) only 55% of multicultural children had positive self-images while almost Korean children had positive self-images; c) multicultural children expressed psychological trauma from peers in school while Korean children expressed psychological trauma from parents at home. Lastly, we discussed implications of the results, limitations and suggestions for future study.

The purpose of this study was to investigate the kindergarten and elementary school teachers' perception on the gifted children and the education for the gifted and the talented. One hundred and fifteen kindergarten teachers and 116 elementary school teachers participated in this study as subjects. Teachers perceptions on the gifted children were generally right, except the relationships between the giftedness and birth order, the domain-specificity of the creativity, and the physical growth, sense of humor, and the socio-economic status of the gifted children. Teachers perceptions on the education for the gifted and talented also were generally right. Especially the elementary school teachers perceptions were higher than those of the kindergarten teachers.

Recently, a lot of index techniques for storing and querying XML document have been studied so far and many researches of them used coordinate-based methods. But update operation and query processing to express structural relations among elements, attributes and texts make a large burden. In this paper, we propose an efficient BitmapInvert index technique based on Relative Position Coordinate (RPC). RPC has good preformance even if there are frequent update operations because it represents relationship among parent node and left, right sibling nodes. BitmapInvert index supports tort query with bitwise operations and does not casue serious performance degradations on update operations using PostUpdate algerian. Overall, the performance could be improved by reduction of the number of times for traversing nodes.

1 인 미디어 산업의 성장으로 다양한 콘텐츠 제작의 증가와 함께 영상의 분위기를 좌우하는 BGM 의 수요도 급증하고 있다. 그러나 무료 음원은 한정되어 있으며 이미 많은 영상에 쓰여 시청자에게 흔한 느낌을 준다. 특히 MCN 에 소속되지 않은 콘텐츠 크리에이터들은 개성 있고 영상에 어울리는 음원 확보에 어려움을 겪고 있다. 본 연구는 이러한 콘텐츠 제작 환경을 개선하기 위해 창작자가 직접 녹음하거나 악보를 스캔해 자신만의 음원을 제작할 수 있는 웹 애플리케이션 '플랫'을 제안한다. 본 연구를 통해 콘텐츠 크리에이터들은 독창적이고 풍성한 콘텐츠를 만들 수 있으며, 음악적 숙련도와 관계없이 쉽게 음원을 만들 수 있어 작곡에 대한 접근성이 좋아질 것으로 보인다. 또한, 딥러닝을 활용해 음악을 창작함으로써 인공지능 작곡 분야를 활성화하고 디지털 음악 시장의 새로운 분야를 개척하는 데 이바지할 것으로 기대한다.

The purpose of the study is to investigate kinds of social support provided by various types of family members, relationships between types of family support and personal variables of the elderly and structural variables of the family network, and the relationships between family support and depression of the elderly. Here, family included a spouse, sons and daughters and their spouses, grandchildren, siblings and parents of an older person. Social support consisted of emotional, instrumental, financial help and social companionship. Two-hundred-eight older persons of age 60 years and over were interviewed. The main results of the study were as follows: an older person's spouse tended to provide more for emotional support, sons for financial help, daughters-in-law for instrumental support, and daughters for emotional and financial support. Some elderly were also provided for emotional support by parents and siblings. Possibility of daughters-in-laws and grandchildren as support providers was also verified. Various factors among personal and network-structural characteristics were significantly related to many types of social support provided by various types of family members. In general, while younger female elders, elders with good IADL ability or more frequent contacts with family members tended to have social support from more family members, support from daughters-in-law was provided to the elderly with less functional abilities. Various types of social support from a spouse were significantly related to depression level of the elderly. Their depression level was more related to whether or not sons and daughters-in-law exist rather than whether or not they provide social support. Practical methods to increase family support for the elderly were discussed.

This study focuses on Ko woo-young (1939-2005), a Korean representative cartoonist. I analyzed his work Nolbudyeon (1988), which is a retelling of Heungbu and Nolbu, a traditional Korean story. I consider Ko woo-young a creative observer who has popularized his perspective in modern society. His work is a good example of how a traditional folktale can be made relevant in modern society. I used three methods of adaptation to differentiate Nolbudyeon from Heungbu story: construction of events, characterizing, and space-time background. First, to aid character development, Nolbudyeon includes a prologue that focuses on conflicts between brothers with different personalities. At the same time, the ambiguous ending could be a response to Heungbu story, which has a didactic theme. Second, I found that the new characters, Nolsun and Yeonsaengwon, enhanced the differences between Heungbu and Nolbu by playing the role of mediators. Also, in Nolbudyeon, both Heungbu and Nolbu had positive as well as negative elements, in contrast with the original story's traditional point of view on good and evil. Finally, by exploring the space-time of Nolbudyeon, we can see that its world is combined with the contemporary world. In other words, Nolbu and Heungbu, though outwardly traditional, have a modern outlook. Therefore, readers can recognize that Nolbudyeon is a metaphor for modern life rather than just an old story.

Role models are also known to influence an individual's job or career choice. The positive effect of role models on entrepreneurship has already been revealed through many precious researches. It is said that people choose not only family members who are related by blood, such as parents, siblings, and relatives, but also acquaintances whom they have met through social relationships as role models. In this study, we divided into entrepreneurs with no role models other than themselves and entrepreneurs with role models. In addition, we classified parental siblings and relative role models as role models with strong ties, and acquaintance role models as role models with weak ties. We analyzed the differences in personal attributes, entrepreneurial orientation factors, and learning orientation between the entrepreneurs with role models and those without role models. Also, the differences in personal attributes, innovativeness, proactiveness, risk-taking propensity, and learning orientation between the entrepreneurs with strong ties role models and those with weak ties role models were examined. The empirical analysis results are as follows. First, it was found that the proportion of women entrepreneurs without role models is higher. Second, the entrepreneurs with role models with weak ties tend to run larger scale start-ups. Third, it was found that the entrepreneurs with role models of weak ties tend to have higher learning orientation. Fourth, gender shows the greatest influence on th absence or presence of role models. Fifth, it was found that learning orientation and startup size have the greatest influence on the decision of the role model with weak ties or that with strong ties.
