This study is designed to explore the function of Twitter as a campaign platform during election campaign. For exploring the function of Twitter the form of tweet, the type of information on tweet and the way of opinion expression via Twitter were discussed by content analysis. This study finds, first, that, netizens express their opoinion of candidates without foundation and with emotional reactions. Second, they showed somewhat conflictive reactions according to their supporting candidates. This study conceptualized various kinds of public as 'blindly support public,' and 'blindly opposition public' in case of Park's supporters, 'rational support public,' and 'critical opposition public' in case of Na's supporters. Third, Park's supporters debated Na candidate's attitude of debate and her appearance blindly without foundation. Na's supporters argued Park's attitude of debate and his ignorance of Seoul Metropolitan government's policy blindly without foundation. Finally, this study discussed the relationship between the political discourse according to netizens' supporting via Twitter and the results of election. Park whose supporters attacked the opposing candidate by blaming her appearance and her attitude of debate won the election. Na didn't overcome her negative images. For her Twitter functioned as a media which is spreading negative factors about her. In conclusion, Twitter as a campaign platform during election times plays a key role in discussing candidates. However, netizens need to express their opinions with foundation and the candidates have to consider negative issue management. This study highlights the importance of peripheral factors which have a decisive effect on the results of election. The results of this study is useful for building political campaign strategy by candidates.

Recently mining techniques that analyze the data stream to discover potential information, have been widely studied. However, most of the researches based on the support are concerned with the frequent event, but ignore the infrequent event even if it is crucial. In this paper, we propose SM-AF method discovering association rules to an abnormal event. In considering the window that an abnormal event is sensed, SM-AF method can discover the association rules to the critical event, even if it is occurred infrequently. Also, SM-AF method can discover the significant rare itemsets associated with abnormal event and periodic event itemsets. Through analysis and experiments, we show that SM-AF method is superior to the previous methods of mining association rules.

Purpose: The purpose of this master's thesis is to utilize basic data in order to improve the quality of life of cancer patients who received radiation therapy after analysing related factors that influence patient's quality of life and obtaining information about physical, mental problems of patients. Materials and Methods: By using a structured questionnaire about various characteristics and forms of support, I carried out a survey targeting 107 patients that experienced radiation therapy at a university hospital in the Daejeon metropolitan area from July 15 to August 15, 2010 and analysed the factors influencing quality of life. Results: In case of pain due to disease, 65.15 and painless 81.87 showed a high grade quality of life. As body weight decreases, the quality of life become lower. When the grade of quality of life according to economic characteristics was compared, all items except treatment period showed a difference (P=0.000). When the score of social support, family support, medical support and self-esteem was low, the mark of quality of life showed respectively 61.71, 68.77, 71.31, and 69.39 on the basis of 128 points. When the score of support form was high, the mark of quality of life showed 90.47, 83.29, 90.40, and 90.36 (P<0.05). When analyzing the correlation between social support, family support, medical support and self-esteem and the degree of quality of life, social support was 0.768, family support 0.596, medical support 0.434, self-esteem 0.516. They indicated the correlation of meaningful quantity statistically (P<0.01). The factors that improved the quality of life were married state, having a job and painless status. As monthly income increases, the quality of life was also much improved (P<0.05). Among the factors related to quality of life, social support and medical support and higher self-esteem scores of the quality of life score increased 0.979 point, 0.508 points and 1.667 point, respectively. Conclusion: In conclusion, the quality of life of cancer patients that received radiation treatment is related to social support, medical support and self esteem. Self-esteem is an important factor that influenced quality of life, so if government offers works that doesn't affect patient's health, they are a useful method that maximize self-esteem and lessen their financial burden at the same time. Along with these policies, the developments of the attention of medical and the program for cancer patient's family are needed for the purpose of improving quality of life of cancer patients. Lastly, medical team, patients and family have to cooperate in harmony to overcome difficulties of cancer patients.

1980년대 후반 국내에 정보시스템 감리 제도가 도입된 이래 그 효과성이 가시적으로 입증됨으로써 감리의 필요성에 대한 인식이 높아지고 있고, 공공기관 뿐만 아니라 민간기업에서도 감리를 시행하는 사례가 늘어가고 있다. 그러나 정보시스템 구축 프로세스에 근본적인 개선이 이루어 지지 않는 한, 감리만으로는 정보시스템 구축 프로세스나 구축된 시스템의 품질향상에는 한계가 있기 마련이다. 이 연구는, 기존의 정보시스템 프로세스의 문제점을 개선하고, 전사적인 정보화활동 관리가 가능하도록 지원하는 엔터프라이즈 아키텍쳐(EA)의 특징을 정리하고, EA에 기반한 감리프레임웤을 제시하였다 EA기반의 감리 프레임웤은 조직의 정보기술 활동이 경영전략과 업무 프로세스와 연계되도록 평가, 권고, 조정할 수 있는 유용한 수단을 제공할 수 있을 것으로 판단된다.

본 논문에서는 한 장의 실제 나무 영상이 주어졌을 시, 사실적인 3차원 나무 모델링(modeling) 및 자가생장(self-growth) 표현을 위한 방법을 소개하도록 한다. 스켈레톤기반의 간략화(skeleton-based abstraction)를 이용하여 동일한 나무 몸통(trunk)을 갖는 다양한 나무 모델생성과 함께 나무의 다면체구조(manifold structure)를 고려한 지오데식 커널(geodesic kernel)을 이용하여 나무의 자가생장을 표현한다. 나무의 자가생장은 사전 정의된 나무 굵기, 전체 크기, 그리고 가지증식 순서정보와 같은 상대적 성장정보(allometric information)를 동시 이용하여 상대적인 나무 생장(allometric tree growth)을 표현하도록한다. 한편, 보여지지않는 나무 가지와 잎들에 대해선, 나무구조는 로컬하게 자기유사성(local self-similarity)을 갖는다라는 고전적인 절차적(conventional procedural) 가정을 이용하여 자동적으로 생성토록한다. 실제영상을 이용한 몇몇들의 실험을 통해 보다 효과적으로 나무 모델 및 생장 표현이 가능함을 보여주도록한다.

This study was conducted to investigate the effects of oral care behavior, oral health care self-efficacy, and social support on the subjective oral health level of the elderly. The data survey was conducted from September 17, 2019 to November 22, 2019 for the elderly living in Daejeon Metropolitan City and parts of Chungcheongnam-do, and the collected data were analyzed by 𝑥2-test, Pearson correlation analysis, and logistic regression analysis. As a result of the survey, subjective oral health level increased by 3.242 times when dentures were not used and 2.339 times when the number of brushings per day was 3 or more times. In addition, as the oral health care self-efficacy and social support increased 1.755 times and 1.192 times, respectively, the subjective oral health level also increased. Based on the above results, in order to improve the subjective oral health level of the elderly, opportunities for oral health education such as denture care methods and toothbrushing lessons should be expanded. In addition, there is a need to prepare policies to reinforce oral health care self-efficacy and social support.

This paper examined whether quality management(QM) positively impacts Kazakh companies' business performance (financial and non-financial performance). As a result of testing ten hypotheses based on the research model for 287 companies in Almaty, only eight hypotheses were supported. Top management leadership was identified as a critical factor that positively affected financial performance, and customer-centered thinking is strongly related to non-financial performance. Employee participation and quality information analysis factors also positively affected business performance, but their influence was lower than top management leadership and customer-centered thinking factors. Finally, the supplier management factor did not significantly affect business performance, and the two related hypotheses were not supported. These results are presumed to be due to the characteristics of the target companies, such as oil and raw material manufacturing and construction, rather than high-quality finished products.
