Turbulent mixing of hot and cold coolants is one of the possible causes of high cycle thermal fatigue in piping systems of nuclear power plants. A typical situation for such mixing appears in turbulent flow through a T-junction. Since the high cycle thermal fatigue caused by thermal striping was not considered in the piping fatigue design in several nuclear power plants, it is very important to evaluate the effect of thermal striping on the integrity of mixing tees. In the present work, before conducting detailed evaluation, three thermal striping evaluation methodology suggested by EPRI, JSME and NESC are analyzed. Then, a by-pass pipe connected to the shutdown cooling system heat exchanger is investigated by using these evaluation methodology. Consequently, the resulting thermal stresses and the fatigue life of the mixing tee are reviewed and compared to each other. Futhermore, the limitation of each methodology are also presented in this paper.

본 연구는 예비유아교사의 통일ㆍ통일교육에 대한 인식조사를 통해 예비유아교사 대상 통일교육의 나아가야 할 방향을 제시함에 목적이 있다. 연구대상은 전국에 있는 4년제 유아교육과에 재학 중인 학생으로 교육부와 통일부(2018), 윤경혜(2005)의 설문 내용을 유아교육 전공 교수 1인과 유아교육 석ㆍ박사과정 5인이 수정ㆍ보완하 였으며 문항 반응 방법 및 문항 내용의 적절성 등의 안면타당도 검증을 받았다. 자료처리는 SPSS WIN 24.0을 사용하여 빈도와 백분율, 평균과 표준편차, t 검증, x² 검증, 일원분산분석(one-way ANOVA)을 실시하였고, 집단별 차이를 알아보기 위해 Scheffé의 사후검증을 실시하였다. 연구결과 첫째, 통일에 대한 예비유아교사의 인식은 대체로 긍정적이며 통일교육 경험에 따른 인식 차이가 있었다. 둘째, 예비유아교사는 통일교육의 필요성을 인식하고 통일교육 강좌에 참여 의사가 있으나 통일교육을 받아본 경험은 별로 없었다. 교사양성과정 내의 유아통일교육 수업 개설에 대한 필요성을 인식하고 있는 반면 전공 관련 유아통일교육 경험은 대부분 없었고, 통일 교육 경험에 따른 인식차이가 나타났다. 따라서 통일교육 경험에 따른 인식 차이를 줄이고 예비유아교사의 통일교육 요구에 응답하기 위해 유아교사양성과정 내의 통일교육 강좌 개설을 제안하며, 이를 위한 기초자료를 제공했다는데 본 연구의 의의 가 있다. The purpose of this study is to present the direction of reunification education for preliminary early childhood teacher through a survey of their awareness of reunification and reunification education. The research targeted nationwide 4-year university student who majored early childhood education. As the research tools, the questionnaires used by department of education & reunification ministry(2018), Yun Kyeong Hye(2005) were used after modification and supplementation to research preliminary early childhood teachers’perception of reunification and reunification education. One early childhood education major professor and 5 masters, Ph.D. courses were modified and supplemented together to reconstruct the questionnaire. For analyzing the data collected, using SPSS WIN 24.0, frequencies and percentages, and average and standard deviation were calculated and t-test, Fisher s exact test, one-way ANOVA and Scheffe were carried out. The results of the study as follows : First, the study found that preliminary early childhood teachers perceptions of reunification were generally positive, changes in perceptions of the situation around the Korean Peninsula and social trends, and differences in perceptions according to reunification education experience. Second, the preliminary early childhood teacher recognized the need for reunification education and was willing to participate in reunification education classes, but hardly experience in reunification education. While recognizing the need to open early childhood reunification education classes within the teacher training course and learning the contents and methods of reunification education needed for actual classes is the most urgent problem but most of them are uneducated about major- related early childhood reunification. This study is meaningful in that it proposed the opening of reunification education courses in the early childhood teacher training course to reduce differences in perception according to reunification education experiences and respond to requests for reunification education.

A Study on the meaning and semantic function of the ``jul`` collocations -Study for selecting and describing grammar patterns in Korean Language Education-. Teaching Korean as a Foreign Language, 37, 97~123. This study is about grammatical collocation in Korean Language textbooks and it aims to find out the collocation based on bound noun ``jul`` in Korean Language textbooks on the view of teaching grammar for the students` practical use of the language. Furthermore, with studying grammatical collocation of ``jul`` in contemporary Korean corpus which consists of 3,000,000 words, this study focuses on the meaning and semantic function, which has not been the focus of much discussion to this point, by combining with other grammatical morphemes to form ``jul`` structures and examining the semantic function and specifying its characteristics. As a result of corpus analysis, collocation of the bound noun ``jul`` have five kind of semantic function. Especially, emphasis of duration, exclamation, discourse marker of the topic development figured out the new semantic functions in addition to fact and method through this study. This is the trial to systematize the teaching material and it tries to study the grammatical collocation, especially of the bound nouns, in the Korean Language textbooks.

Piping failures due to thermal fatigue have been widely reported in normally stagnant non-isolable reactor coolant branch lines. Since the thermal fatigue due to thermal stratification was not considered in the piping fatigue design in old NPPs, it is important to evaluate the effect of thermal stratification on the integrity of branch lines. In this study, geometrical screening criteria for Up-horizontal branch lines in MRP-132 were applied to SI(Safety Injection) lines of KSNP 2-loop and WH 3-loop. Some computational fluid dynamic(CFD) analyses on the Reactor Coolant System(RCS) branch lines were also performed to develop the regulatory guidelines for screening criteria. As a result of applying MRP-132 screening criteria, KSNP 2-loop and WH 3-loop SI lines are determined to need further detailed evaluation. Results of CFD analyses show that both valve isolation and amount of leakage through valve can be used as technical bases for the screening criteria on the thermal fatigue analysis.

Neisseria sicca is a Gram-negative diplococcus found in the human oral mucosa and upper respiratory tract. Although colonization generally does not result in severe infection, some cases of infection have been reported, particularly in immunocompromised individuals. However, Neisseria sicca has not been reported as a pathogen of continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis in Korea. Here we describe a case of CAPD-related peritonitis due to Neisseria sicca in a patient with poorly controlled diabetes mellitus undergoing peritoneal dialysis.

Piping failures due to thermal fatigue have been widely reported in normally stagnant branch lines connected to reactor coolant system (RCS) in nuclear power plants (NPPs). Since the thermal fatigue due to thermal stratification was not considered in the piping fatigue design in old NPPs, it is important to evaluate the effect of thermal stratification on the integrity of branch lines and to prepare inspection and management program against the thermal fatigue. In this study, some computational fluid dynamic (CFD) analyses on the branch line connected to RCS in domestic NPP were performed to develop the regulatory guidelines for screening criteria and fluid analysis for the thermal fatigue evaluation. The result shows that both valve isolation and amount of leakage through valve can be used as technical bases for the screening criteria on the thermal fatigue analysis. The turbulent model, buoyancy model, and piping thickness should be adequately considered in the CFD analysis.
