반도체 제조업은 정해진 시간 내에 최고의 품질의 반도체를 대량 생산해 내는 것을 목표로 한다. 생산량을 높이기 위해 유휴 시간을 최소화하는 연구가 꾸준히 진행 중이며 가장 대표적인 유휴 시간은 예방 정비이다. 예방 정비는 설비의 문제가 발생하기 전 예방하는 작업으로 품질 향상에 높은 영향을 미치는 작업인 반면 생산량이 크게 떨어지는 작업이다. 이 작업 시간을 최소화하기 위하여 작업 후 복구되는 시간에서 중복되는 작업을 최소화하는 방법을 선택한다. 샘플 테스트를 반복하며 조율해 나가던 작업을 연구 모델을 이용해 종말점 설정 값의 예측한 값을 바로 적용하여 최소한의 샘플 테스트를 거쳐 신뢰 구간 달성 후 생산에 재 합류하는 것을 목표로 한다. 설비에서 수집된 데이터를 학습하여 종말점 설정 값 예측 모델에 대하여 연구한다. 연구 모델을 사용한 예측 결과가 신뢰 구간에 포함되어 샘플 테스트 개수를 줄이는데 유효한 효과가 있음을 확인한다.

노인장기 요양보험제도가 시행된 지 2년이 흘렀다. 그동안 가족이 책임졌던 노인에 대한 장기요양을 국가와 사회가 부담함으로써 만성질환 및 노인성 질환으로 어려움을 겪는 노인과 가족들의 부담이 줄어들었다. 하지만 적지 않은 문제점도 드러나고 있다. 외국의 사례를 통해 우리나라 노인장기 요양보험제도의 현재와 미래를 그려보고자 한다.

Familial adenomatous polyposis(FAP) is an autosomal dominant disease characterized by numerous adenomas in the colorectum. Patients with FAP are always at risk of malignant transformation, so that colectomy is unavoidable. NSAID, such as sulindac, and selective COX-2 inhibitor, such as celecoxib, have shown a positive effect on FAP by causing polyp regression in some patients. We report a case of FAP in a 9-year-old female whose polyposis regressed markedly after six months-treatment with celecoxib.

건유기에서 비유기로의 이행기는 젖소에서 위험률이 높은 시기이고 이 시기에 가장 큰 문제가 될 수 있는 것이 유방염이다. 환경성 세균들이 분만 전후기에 가장 문제가 될 수 있는 병원체이다. 대장균군에 속하는 세균들은 경산우에서 심각한 감염을 일으킬 수 있고, 처녀우의 경우는 coagulase-음성 포도상구균에 감염될 가능성이 높다. 분만 전후기 중에는 호르몬이나 기타 요인들로 인해 젖소들의 면역상태가 다소 억압된다. 성공적인 유방염 방제 프로그램은 건유우, 분만우, 및 처녀우의 관리에 초점을 맞춰야 한다. 청결하고 안락한 환경, 적절한 사료공급, 비타민과 미량 원소가 함유된 적절한 사료의 보충이 유방 건강을 유지하는데 필수적이다. 건유 시작할 때 유두관의 폐쇄를 강화하고 케라틴 마개가 형성될 때까지 유두 끝을 세균으로부터 보호해 줄 전략들을 사용해서 분만 후의 유방염 감염 위험을 감소시켜야 한다. 건유기 치료는 상당히 성공적으로 이용되어 왔지만 전체적으로 실시하기 보다는 선택적으로 치료하는 접근법이 권장된다. 환경성 유방염에 감염될 위험이 높은 우군에서는 항생제 이외의 접근법이 건유기 중의 신감염 예방을 위한 유용한 도구가 될 수 있다.

This study aims to provide future direction recognizing the educational importance and to present the way ahead that practices correctly for improving an educational role on security sector to prevent child missing. Therefore, it was conducted with questionnaire that is "Research on participation grade of education to prevent child missing and the actual condition" made by researcher of this study which is on 363of parents of pre-chirdren of 6,7 and 8years old in a kindergarten and an elementary school where is located in metropolitan area. It operated to take processing enterprise statistics using SPSS/WIN 12.0 for getting data, and analyzed frequency and t-verification.It investigated correct selection of an education specialist on preventive education and participation grade of education to prevent missing on home, how often, how it is conducted, then what requirement for educationto prevent child missing and participation grade is, whether difference is in accordance with gender of parentsand gender of child.

This study aimed to develop the standardized contents and methods for preventing sexual harassment for hight school students preparing for employment after graduation. Delphi methodology was used with 30 experts. Three-round Delphi surveys were analyzed using Kendall's coefficient of concordance W analysis, appropriateness for reliability of consensus opinion. Data were analyzed respectively by descriptive statistics using SPSS Win version 20.0. Results of this study showed that standardized contents were classified with 3 domains and 83 contents, then 46 contents were selected from Kendall's W analysis and weight rank. Finally, 37 contents have taken as standards contents for prevention education. If high school students are educated with systematic standardized education before employment, it will be prevented sexual harassment in the workplace after graduation.

The value of a statistical life (VSL) plays a very important role in estimating the benefits of environmental policy. It is used, for example, as a unit of monetization of health benefits resulting from the reduction of air pollutants, which is the basis of cost-benefit analysis of policies. The VSL can be defined as the value that people of each society are willing to pay to reduce the risk of death, so the value should reflect the characteristics of its members. In this study, we apply a choice experiment with 3,081 respondents collected through a web survey were divided into two samples according to the type of questions. Among the various estimates, the most appropriate estimate of the VSL is about 1.3 billion won from 1,528 sample, which is similar to the results of the meta-analysis using estimates from prior studies conducted in Korea. In addition, this study shows that a private prevention program is preferred to reduce the risk of death from cancer rather than a public program.

Patient with congenital heart disease are susceptible to infective endocarditis, and bacteremia following dental procedures may lead to infective endocarditis is these patients. Therefore prophylactic antibiotics are recommended for patients with congenital heart disease who are undergoing dental procedures that are associated with infective endocarditis. In 1997 American Heart Association revised guidelines for a prophylaxis against infective endocarditis. The new American Heart Association recommendations for the prevention of infective endocarditis represent a substantial departure from past guidelines. Major change involve the indications for prophylaxis, antibiotic choice and dosing that may reduce bacteremic risk. Previously, antibiotic prophylaxis was suggested for dental procedures associated with any amount of bleeding. Now only those that are associated with significant bleeding are recommended for prophylaxis as dictated by clinical judgement. Recommended antibiotic prophylaxis regimens now consist of a single preprocedural dose, no second dose is recommended. This report presents three cases of dental treatment of patients with congenital heart disease under the most recent American Heart Association recommendations for antibiotic prophylaxis.

The purpose of this study is to provide a theoretical base for making a character education program and to develop a school violence prevention program and analysis the effects of the program in elementary schools. The prevention program was designed to target students, teachers, parents and community residents and utilized the above groups as participants. This study is developed on the basis of Social Emotional Learning as well as Emotional Intelligence which put on the importance on the role of emotion in the problem solving. In concrete, school violence prevention program based on the social and emotional learning, development of integrative programs articulating three key domains directly and indirectly influencing students' character formation, maximum use of the educational institutes' moral education curriculums and potential curriculums in the surrounding environment. To do so, bibliographical study and analysis of the research materials are carried out, and also the professionals' advice is received. The study object is 113 elementary school students of 2 elementary schools in Seoul. For them, the preparatory program is carried out from September 2009 to November 2009. And then, the analysis for the satisfaction degree of participation in the program and for the descriptive results of the school violence prevention education is carried out.
