The purpose of this study is to investigate the strategy of representation of homosexuality in the mainstream media and its meaning. And it also concerns what would be the limit of representations of homosexuality and what would be the discourse these representations produce in the major terrestrial broadcasting. For this investigation, we conducted the analysis of , the mainstream television drama, focused on the gay couple characters and their representations of conflicts and resolutions by comparing with the two heterosexual couples to figure out the differentiated representation strategies of homosexuality. As results of the analysis, the representation of sociogenic cause of conflict is absent for gay couple while it was found in the case of one heterosexual couple. And gay couple is exposed to the interpersonal conflicts against their family members than heterosexual couples and described as victims. Lastly, gay couple was represented as needing mediators to solve their problems while heterosexual couple was represented as ensuring subjectivity for the resolutions of conflicts.

Most warship combat systems inquire human operator to control several sensor and another equipments as well as decision-modeling. For this reason, many researches with multi-agent based M&S (Modeling and Simulation) have been increasingly conducted. However there cannot find any researches of M&S based analysis for anti-submarine warfare that requires a high level of mission complexity between multiple platforms. In this research, we have been developed various combat platform models such as warship, submarine and helicopter, etc. In order to apply the multi-agent-based M&S technology to the anti-submarine warfare i.e. a HVU (High Value Unit) escort mission scenario. Then we have successfully analyzed the measures of effectiveness according to the different tactics and different situations. In future, the defence engineer maybe employ our methodology and tools to analyze actual tactical problem by simply inserting actual data into our agent model.

The purpose of this study was to examine the degree of depression in housewives and to analyze the effects of psychosocial factors on the depression. Especially the focus was on the differences in the degree of depression and the influencing factors on depression between those in early adulthood and those in middle adulthood The subjects consisted of 130 early adulthood housewives and 142 middled adulthood housewives. They asked to complete several self-report measures that were used to assess the variables of interest. The result indicated that the depression in housewives were serious enough to arouse social workers' attention. The average housewives were suffered from mild depression, and 17.1% of the housewives were in need of professional treatment. There was no significant difference in the degree of depression between the early adulthood housewives and the middle adulthood housewives. There were, however, differences in the factors which explain and predict the depression between these two groups. The results of step-wise multiple regression analysis indicated that the factors which predict the depression for the early adulthood housewives were self-esteem, conflict with the spouse, experience of painful events, age, and conflict with the children. On the other hand, the factors which predict the depression for the middle adulthood housewives were self-esteem, conflict with the spouse, job, and income. Implications of the findings for social work interventions were discussed.

The purpose of this study was to investigate the relationship between child maltreatment, protective factors, and resilience in elementary school students. It was especially focused on what direct effect of the risk factor(child maltreatment) and protective factors to child resilience, and how protective factors affect the resilience of maltreated child. In the concrete, this study intended to find out whether protective factors mediate between child maltreatment and resilience. This study based on data from the first wave of 'Korean Youth Panel Survey(KYPS)' and subjects consisted of 2,844 4th grade elementary school students. In addition, to test the proposed models, the Mplus-structural equation modeling-was used. The major findings are as follows: First, when child maltreatment increased, resilience decreased. Second, when protective factors increased, resilience increased. Third, protective factors act as buffers against the negative effects of child maltreatment on resilience by mediation. Results indicated that child maltreatment related negatively to resilience and protective factors related positively to resilience. In addition, a mediational model in which protective factors mediates child maltreatment and resilience was supported. In conclusion, various theoretical and practical implications for social work practice focusing on the maltreated children were discussed.

Although the number of adolescents with complicated problems and needs has increased, there has been a limited service for this population. In addition, a traditional social service could not alleviate the problems. In order to provide an alternative to a traditional social service to this population, the wraparound model is reviewed and explored. The study presents a review of literature on wraparound and social work via EBSOCO. By reviewing 12 articles on the subject, the study discovers 3 topics, such as (1) youth with various problems, (2) general characteristics of wraparound, and (3) evidence-based practice and wraparound. Based on 3 topics, the study also discusses the feasibility of wraparound service in Korea.

A fundamental assumption in conventional linear predictive coding (LPC) analysis procedure is that the input to an all-pole vocal tract filter is white process. In the case of periodic inputs, however, a pitch bias error is introduced into the conventional LP coefficient. Multi-pulse (MP) LP analysis can reduce this bias, provided that an estimate of the excitation is available. Since the prediction error of conventional LP analysis can be modeled as the sum of an MP excitation sequence and a random noise sequence, we can view extracting MP sequences from the prediction error as a classical detection and estimation problem. In this paper, we propose an algorithm in which the locations and amplitudes of the MP sequences are first obtained by applying a likelihood ratio test (LRT) to the prediction error, and LP coefficients free of pitch bias are then obtained from the MP sequences. To verify the performance enhancement, we iterate the above procedure with adaptive threshold at each step.

21세기에 들어 홍수의 규모가 대형화 되었고, 그 발생빈도 및 강도도 증가하고 있다. 최근에는 지구온난화가 지속화되면서 전 세계적으로 높은 강도의 기상이변들이 속출하고 있고, 이러한 이상기후에 따른 태풍, 집중호우 등의 대규모 호우로 인해 댐 및 제방 등의 수공구조물 붕괴와 같은 비상상황이 초래 될 수 있다. 이와 같은 피해들을 통해 홍수 침수 범위의 예측, 분석을 통한 홍수위험 및 다양한 홍수위험지도 작성의 필요성이 대두되었고, 실제로 국가 차원의 홍수위 험지도가 제작되고 있다. 특히, 홍수 위험도 분석에 있어서 홍수에 노출된 지역의 인구수, 홍수에 노출된 지역에서의 경제적 활동의 형태, 홍수가 발생했을 때 2차적 피해를 불러올 수 있는 설비 등을 나타내는 홍수 취약도(Flood Vulnerability)에 대한 정량적 평가는 홍수위험지표 및 홍수위험강도 등에 의한 Flood Risk 개념을 기반으로 한 홍수위험지도 제작을 위해 매우 중요한 사항이라 할 수 있다. 그러나 현재까지의 홍수취약도 산정방법은 방법론적인 면에 있어 다소 단순하고, 직관에 의한 위험도의 분류가 이루어지고 있는 실정이다. 또한 취약도 지표의 산정과정이 전문가의 의견에 의존하는 경우가 많아 홍수 취약도 선정과정과 가중치 결정과정에 전문가들의 주관이 개입되는 등 홍수위험지표의 정량화에 어려움을 겪는 경우가 많다. 본 연구에서는 위와 같은 문제를 극복하기 위해 Flood Risk Mapping 기술의 적용에 있어 중요한 요소인 홍수취약도를 다기준의사결정법에 의해 산정하고, 국내 낙동강 유역에 대해 행정구역별로 세분화된 홍수위험지도 제작을 위한 취약도 지표를 산정하고자 하였다. 이를 위해 다기준의사결정법중의 하나 인 PROMEETEE와 ELECTRE를 이용하여 민감도, 노출도, 저감성 지표를 낙동강 유역에 대해 정량화하여 도시하였다. 본 연구결과를 통해 홍수위험지표 및 지수들의 결합에 대한새로운 방법론을 제시하고, 그에 따른 지도화 기법을 확립할 수 있을 것으로 기대된다.

LIDAR data, as the source of the 3D information of buildings, are used many modeling fields such as three-dimensional city models in urban planning and the visibility analysis of buildings. This study suggests a methodology, that is characterized by combining image-based and point-based process, for minimizing the user's intervention and automatically extracting building boundary only using the LIDAR data. Image processing methodology is firstly used to separate building and non-building regions from LIDAR data. Moreover, building regions are then classified main roof into remaining parts by the statistical analysis of height values, and the remaining parts are processed separately. Through the experimental results of study areas which exist many types of buildings, for example, apartment-type, stair-type, complex-type, etc. Approximately 90% building boundaries are automatically extracted by the proposed methodology.

This study aimed to investigate the difference of the disabilities type of caring competency, caring appraisal(caring burden, caring satisfaction), self-help group support for parents who have children with disabilities. The data were collected by a self-reported questionnaire from 301 parents who have disabled children(180 mental disabilities & 121 physical disabilities). Given the three types of invariance satisfied, latent means analysis(LMA) is performed to test mean differences on the four factors across the two groups. According to LMA where the parents who have children with physical disabilities are used as the reference group, the parents who have children with mental disabilities showed higher latent mean values on the self-help group support and caring burden. However, the parents who have children with physical disabilities showed higher latent mean values on the caring satisfaction and caring competency.

This study explores the way of prescribing the ethic of science in korean society in the 2004 ethical debates about 'Hwang woo-suk' embryo stem-cell study. It is the process of ethical communication. The debate includes very sensitive problem such as ovum and embryo, which is related directly with life. Particularly, this issue has many implications as there was a wild enthusiasm of patriotism in Korean society after had published Prof. Hwang's paper. This case shows dramatically the formation of ethical attitude in our society. There were included many actor's desire, interest, and conflicts. This study analyzes the process of competition to seize the initiative of the definition of ethics. It includes patriotic discourse, competition of rhetorics. This ethical communication involves the making of 'star scientist', Hwang woo-suk. In consequence, the ethics has been marginalized and stigmatized as anti-science on the stage of star scientist. This study argues ethics is not a fixed thing, it is construction of competition.
