There is literature addressing to cultural aspects of alcohol and alcoholism. However, scholars have paid little attention to study what will happen to alcohol consumption behavior and alcoholism if there is a national government cultural intervention, so that the alcohol drinking culture would change in association with the change of internal institution in a society. This work attempted to study this research question. For this purpose, I selected Mongolia as a research case and examined survey data, statistical data, and data from research-based resources, referring to the last 70 years profile of Mongolian alcohol per capital consumption and alcoholism as well as studying Mongolian historical sources for measuring Mongolian traditional alcohol drinking customs. The data I gathered and observed during this research proved that there is a huge difference between the current drinking culture among younger generation and Mongolian traditional cultural context that was respected and strictly followed by their ancestors. Findings suggest that there has been a parallel increase between the change of alcohol drinking culture and alcohol consumption in connection with the modernization.

In this paper, I propose an automatic analysis method of golf swine from single-camera video sequences. I define necessary swing features for automatic swing analysis in 2-dimensional environment and present efficient swing analysis methods using various image processing techniques including line and edge detection. The proposed method has two characteristics compared with previous swing analysis systems and related studies. First, the proposed method enables an automatic swing analysis in 2-dimension while previous systems require 3-dimensional environment which is relatively complex and expensive to run. Second, swing analysis is done automatically without human intervention while other 2-dimensional systems necessarily need analysis by a golf expert. I tested the method on 20 swing video sequences and found the proposed method works effective for automatic analysis of golf swing.

An accurate prediction of electricity supply and demand is important for daily life, industrial activities, and national management. In this paper electricity sales is predicted by time series modelling. Real data analysis shows the transfer function model with cooling and heating days as an input time series and a pulse function as an intervention variable outperforms other time series models for the root mean square error and the mean absolute percentage error.

인간의 유전자의 돌연변이 서열인 SNP를 통하여 하플로타입을 추정하는 연구는 생명공학분야에서 중요한 연구분야이다. 일반적인 방법으로 하플로타입을 추정하는 것은 상당한 시간과 비용이 요구된다. SNP를 통한 하플로타입 추론에 대한 방법은 지금까지 여러 방법이 제시되었다. 본 논문에서는 해당 문제를 해결하기 위한 도구로 베이지안 네트워크를 제시하고, 이를 사용한 유전알고리즘인 BOA를 이용하여 해결하는 방법을 제시한다. 이후 BOA 소프트웨어를 이용하여 우선적으로 해집단크기 및 비율에 대한 정확도를 분석 후 적합도함수의 quality정보의 개입유무에 따른 정확도를 실험한다. 마지막으로 네트워크의 간선존재 여부에 따른 정확도를 실험하는 것으로 실험을 마친다. 실험결과 해집단크기와 비율에 따라 정확도가 상이한 결과를 얻었으며, quality정보의 개입이 없는 경우와 네트워크의 간선을 적용한 경우 모두 기존에 비해 저조한 정확도를 보였다.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

The purpose of this study was using a meta-analysis to estimate effect size ACT intervention program. Using a statistical method, meta-analysis has advantages that prove intervention's amount and direction. Meta-analysis facilitates comprehensive analysis. Through the data collection, 43studies were selected and 183 effect size were calculated as analysis objects. Using a 183 effect size, the overall effect size, Effect Size of categorical Factor, meta-regression result were suggested. The overall effect size of ACT program was 0.704. In the effect area of ACT, the affective domain had the largest effect size. Next were the cognitive domain, the behavioral domain. Analysis on gender of participant, mixed group had the largest effect size. Next were the female grouop, male group. Analysis on age of participant, adult group had the largest effect size. Next were the undergraduate grouop, adolescent group. Based on the findings, implications for future study were discussed.

본 논문에서는 비상운전 상황하에서 표출되는 운전원들의 직무전략 및 인지적인 특성을 도출하기 위해 운전원 교육 프로그램을 대상으로 운전원들의 직무특성을 분석하였다. 운전원들의 직무특성을 인지과정의 개입 정도에 따라 크게 Macro와 Micro로 구분하여 이들 직무특성을 잘 대변해 줄 수 있는 비상운전 시나리오를 개발하였다. 시뮬레이터를 통해 개발 시나리오에 따른 운전원들의 비상운전절차 수행과정을 비디오로 기록, 운전원들의 행동과 대화내용을 전산 분석하여 직무특성을 도출하였다.

본 연구는 실시간 개인 방송에서 이뤄지는 담화의 상황을 통접, 이접, 연접이라는 질 들뢰즈의 개념으로 분석하고, 실시간 개인 방송에서 나타나는 시청자의 개입 행위와 그로 인해 끊임없이 변화를 거듭하는 방송의 진행 양상을 '특이점(point singulier)'과 '사건(${\acute{e}}v{\acute{e}}nement$)' 개념을 통해 분석했다. 구체적인 연구 대상으로는 아프리카TV의 <대도서관TV> 채널의 '24시간 연속 생방송'편을 선정했다. 본 연구는 국 내외적으로 산업적 규모가 확장되고 있으며, '방송의 개인화'를 불러오고 있는 MCN 방송 콘텐츠 중 실시간 개인 방송의 진행 원리와 그 미학적 함의를 도출했다는 점에서 의의를 지닌다.
