최달님,김형종 서울여자대학교 컴퓨터과학연구소 2011 정보기술논문지 Vol.9 No.-

DEVS(Discrete Event Systems Specification) 기반 분산 시뮬레이션은 이산 사건 시스템을 구성하는 계층적 모델을 다양한 활경에 분석하고, 이들을 하나의 통신 미들웨어로 제어하여 시뮬레이션을 수행한다. 분산 시뮬레이션 환경에서, 특별히 별도의 시스템에서 시뮬레이션 모델의 실행을 요구하는 경우 이를 처리하기 위한 방법들에 대한 고려 및 이들에 대한 비교 분석이 요구된다. 본 연구에서는 분산 환경에서 특정 모델이 별도의 시뮬에이터로의 독립되어야 할 경우 가능한 해결책 4가지를 제시하고, 이들에 대한 장단점을 분석하였다. 본 연구의 기여점은 분산 시뮬레이션을 수행하는데 있어서 발생할 수 있는 모델독립실행에 대한 방법 제안 및 각 방법에 대한 효과 분석에 있다.

Dal-Nim Yang,Kyung-Sook Hwang,Ha-Jeong Kwon,Yong Duk Park 대한예방치과학회 2015 International Journal of Clinical Preventive Denti Vol.11 No.1

Objective: 3-3-3 Brushing Method Campaign was recommended to the people thanks to high awareness, education effect and publicity. However, the necessity about new teeth brushing campaign has been suggested recently, because of the low scholar evidence and practice over 3-3-3 Brushing Method Campaign. Therefore, the purpose of this study is to propose the paradigm of new teeth brushing campaign based on the research and brushing method of each country. Methods: The campaign is claimed on the basis of the preceding articles and directions related to toothbrushing. In particular, We would to deploy based on the grounds of the ADA, the pioneer in the study of these practices. Results: The meaning of 1-2-3 Brushing Campaign is like the below. First, the meaning of 1 of the 1-2-3 Brushing Campaign is a tooth brushing within 1 minute after having a meal. Second, ‘2’ is that a tooth brushing should be continued at least for over 2 minutes. Third, ‘3’ is the person should be brushing teeth at least 3 times a day-just after having a meal. At last, the meaning of the 7 is that a person should rinse the mouth over 7 times whenever it brushes teeth. Conclusion: 3-3-3 Brushing Method Campaign has many advantages, but disadvantages. Especially, there is a need to think about which affects the risk the whole body health after tooth brushing, because 3-3-3 Brushing Method Campaign is focused only on the brushing time and the number of the brushing. Therefore, 1-2-3 Brushing Campaign is very important on the point of view that suggests the right way of tooth brushing and guideline which is necessary to ensure the safety of the whole body health

The oral health facilities of schools can be divided into the school of dental clinic and the tooth-brushing facilities, and the goal is to improve the oral health of children effectively in special-education schools as well as ordinary primary schools. Thus, the study over the oral health facilities of schools is being processed on the various points of view. In this study with the former ones, the survey toward the people dispatched to the school of dental clinic from the public health centers and the people in charge of the school of dental clinic and tooth-brushing facilities in primary schools, including special-education schools has been carried out to analyze their opinions over the oral health facilities of schools. The subjects of the survey are 190 people related to School Oral Health Facility in 17 public health centers nationwide, 288 people who manage the School Dental Clinic in primary schools and special schools and 82 people who operate the School Tooth Brushing Facilities in primary schools. As a result of analysis, the factors which affect the preference of School Oral Health Facility are the form of the workforce and the efficiency of the management and operation - the confidence interval is 95%. However, there is no similar factor over the survey toward School Tooth Brushing Facilities.

이 연구에서는 치과의료기관 이용자를 대상으로 민영치과의료보험의 인식도와 가입 현황을 조사하였다. 서울·경기 지역의 10개 치과의료기관을 방문한 이용자 중 20세 이상 성인 540명을 대상으로 자기기입식 설문조사를 시행하였다. 대상자의 인구·사회적 특성과 건강 및 의료 관련 특성을 분석하였으며, 민영치과의료보험의 인식과 가입에 영향을 미치는 요인을 분석하기 위해 로지스틱 분석을 실시하였다. 민영치과의료보험은 도입된 지 4년 밖에 되지 않아 민영의료보험에 비해 인식도가 낮고 가입률도 17.4%로 낮으나, 치과 이용에 따른 경제적 부담으로 향후 가입을 고려하는 사람의 숫자는 많았다. 민영치과의료보험 인식도에 영향을 미치는 요인은 국민건강보험 만족도, 민영의료보험과 민영치과의료보험 가입, 주관적 구강건강 상태, 흡연이었다. 민영치과의료보험 가입에 영향을 미치는 변수는 연령, 민영치과의료보험 인식도, 민영의료보험 가입, 흡연, 치과의료기관 방문 횟수였다. 향후 민영치과의료보험 가입자 증가로 인해 치과의료 이용의 양적·질적 변화가 일어날 가능성이 있으므로, 민영치과의료보험의 가입률과 치과 이용에 미치는 영향에 관한 후속 연구가 필요하다. This study investigated the awareness and purchase status of the private dental insurance. Self-reported survey was conducted with patients over the age of twenties who visited dental institutions located in Seoul Metropolitan City and Gyeonggi Province. The demographic and health related characteristics of respondents were analyzed, and logistic regression was conducted to examine factors affecting the awareness and purchase of private dental insurance. Because only four years had been passed since the introduction of private dental insurance, the awareness and purchase rate was found to be low. However, the number of people considering subscription due to the economic burden of dental care service was relatively high. Factors affecting awareness were satisfaction of the national health insurance, purchase of private health insurance and private dental insurance, self-perceived dental health status, and smoking. The variables affecting purchase of dental insurance were age, awareness, purchase of private health insurance, smoking, number of visits to dental institution. Because qualitative and quantitative change would be made in the dental care utilization due to the rapidly growing dental insurance subscribers, further studies regarding the trend of purchase rate of private dental insurance and the effect of dental insurance on use of dental institution are needed.

M&S 기반의 가상환경 설계운영은 자원절약 및 위험성 감소 등 다양한 측면에서 효율성을 지니고 있다. 국방은 현실세계에서 실시하기 어려운 군사작전 시뮬레이션 운영을 위해 국방 M&S 개념을 도입하고, 이를 기반으로 무기체계의 소요도출부터 전력화 단계까지 프로세스 전반에 걸쳐 가상 환경에서의 설계 운영 및 검증을 수행하는 SBA 를 도입하였다. 그러나 모델링 및 시뮬레이션 과정에서 발생되는 고비용, 위험성 등의 문제점은 SBA 도입 효율성에 대한 논란의 요인이 된다. 따라서 SBA 도입 효과를 입증할 수 있는 지표 제시가 요구되며, 이 연구에서는 입증 지표로서 비용, 시간, 품질 및 위험도의 4 가지 요소를 분석한다. 또한 소프트웨어 개발비용 산정의 어려움 및 SBA 의 고비용 가능성을 이유로 SBA 에 대한 개발비용 산정의 필요성을 제기한다. SBA 개발비용 산정을 위해 기존에 제시된 소프트웨어 개발비용 산정 모델 적용을 제안하고, COCOMO 모델, Putnam 모델, FP 모델, 전문가의 감정 및 델파이 기법 등 소프트웨어 개발비용 산정모델을 기반으로 SBA 개발비용 산정에 적합한 모델을 분석한다.

The halitosis could be caused by several reasons; among the reasons, the bad oral surroundings, the oral disease and hyposalivation are the causes of the oral part. The halitosis is divided into genuine halitosis, pseudo halitosis and halitophobia. The genuine halitosis could be measured by object inspection and incurred by physiological and pathological reasons. The pseudo halitosis does not have the objective symptoms, it does not realized by other people but the person itself feels the smell. The halitophobia patients believe that they have the disgusting smell even after the treatment for genuine halitosis or pseudo halitosis. The study over the halitosis has been processed for a long time, but there has been no examination about the difference over the halitosis between the people who majored in dental hygiene and the others, so this study was started to make additional data about the halitosis.

This study attempts to demonstrate the application of the multipurpose skylight system, which is equipped a steeply sloped skylight on the roof of building with thermal storage wall function. In this study, the numerical model developed can be used for evaluation of performance of the multipurpose skylight system in the seasons of winter and summer. Using this numerical model, the winter and summer modes are analyzed. The results will indicate that the multipurpose skylight system can indeed perform better than the normal skylight in various climates. The new skylight system is proved to be an effective techniques for improvement of environmental performance in building. Finally, on the basis of this research, the architectural design pattern study should be performed in the future.

Objective: This study explained the harmfulness of smoking in the dental because the oral organization is affected directly. Nevertheless, there was no research work over the harmfulness of smoking in the dental area. Especially, smoking caused the disease, the adverse effect over the treatment and the social expense resulted from the disease and adverse effect. Methods: Dentists have lots of chances to contact with patients, so dentists could comprehend the smoking state of the patients well. In some surveys, general people said that a dentist was the most proper specialist for the treatment to stop smoking. Results: Thus, dentists could be a specialist for the treatment to stop smoking like doctors and nurses. In Korea, the pre-insurance service started in March, 2015. However, most Korean dentists lack of experience as a specialist for the treatment to stop smoking. Conclusion: Therefore, the standard recommendation for the treatment to stop smoking by the Association of Korean Dentists is needed.
