The importance and role of preservice and inservice inspection(PSI/ISI) for nuclear power plant components are intimately related to plant design, safety, reliability and operation etc.. The Korea Atomic Energy Research Institute(KAERI) has been performing PSI/ISI in Korea since the PSI of Kori nuclear power plant, unit 1 had been performed in 1977. KAERI has localized PSI/ISI technology and has done much experience in ultrasonic flaw detection, evaluation and its excavation on the weldments of large pressure vessels. The results of flaw estimation using ultrasonic examination are compared with the actual flaw sizes revealed by field excavation. KAERI's experience regarding PSI/ISI was described and some discussions were added.

The Mathematics Teaching Efficacy Beliefs Instrument is one of the most popular instruments used to measure elementary preservice teachers' efficacy beliefs in mathematics teaching. The instrument was, however, developed in the United States and is perhaps not appropriate for other cultures. In this study, the instrument was translated into Korean and carefully reviewed by Korean mathematics teacher education professors. Analysis of the review indicated that eight out of the 21 items were appropriate while the others needed to be revised. Items were identified as inappropriate due to awkwardness, multiple meanings, tense disagreements, and vagueness. These items were modified to better fit the Korean context. The instrument was revised with two versions: one for elementary and the other for secondary pre service teachers.

현재 국내의 원자력(原子力) 발전소(發電所)는 경수로형 원자로(PWR)가 대부분이며, PWR의 경우 ASME Sec. XI의 요건에 따라 가동전(稼動前) 중(中) 검사(檢査)(preservice and inservice inspection)을 핵연료 교체 및 정기 보수 기간에 수행하고 있다. 현재 83년 및 86년 규격들이 검사에 적용되고 있으며 조만간 89년 규격(規格)이 적용(適用)될 시점이다. 따라서 원전 주요 부품에 대한 ASMB규격의 검사(檢査) 요건(要件)의 변화(變化) 과정(過程)을 살펴 보고 검사 강화 및 완화 내용을 검토하였다. 규격은 71년부터 89년까지를 대상으로 편집년도기준(編輯年度基準)으로 검토하였으며, 부록판의 내용은 제외하였다.

The study aims to find out and examine the variables that make a difference between pre-service teachers' child care efficacy (CCE) and general self-efficacy (GSE). The subjects were 232 pre-service child care teachers going to an educational institution and a college. The results are as follows. First, the variables of "age", "teacher training facilities", "field experience in child care centers", and "experience of child care" and "paraprofessional teachers" are important variables in pre-service teachers' CCE. Second, the variables of "age", "level of education", "teacher training facilities", "field experience in child care center", and "experience of child care or paraprofessional teachers" significantly affect the pre-service teachers' GSE. Third, the "age" variable is essential in explaining pre-service teachers' GSE. The Pre-service teachers' GSE is significantly related to the pre-service teachers' CCE.

From the investigation perfomed by this writer in 1986, it was recognized that many science teachers are in difficulty in teaching the intergrated science in secondary schools and then the present teacher preparation programs need improvement to advance the quality of science teachers. To set up the improvement model, the preservice programs in the departments of science education in Korea were intensively analyzed and compared with that in the department of science education in Hiroshima university. The results of analysises on the programs showed the needs for improvement. A improvement model of the program for secondary science teacher preparation was set up as follows; 1. The improvement program is set up to emphasize the basic science course such as, general physics, chemistry, etc. 2. More emphasis is put upon the intergrated science course. 3. The improvement program is a practical one which is suitable to apply directly as a program in the department of science education.

교수효능감은 교사가 교실에서 얼마나 효율적으로 가르칠 것인지를 예측하는 매우 강력한 구인이다. MTEBI는 초등 예비교사를 대상으로 수학 교수 효능감을 재는 유효한 척도이다. 그러나 MTEBI는 미국에서 개발되어 다른 문화에서 바로 사용할 수는 없다. 본 연구는 MTEBI가 한국에서 유효한 지에 대한 실증적 조사이다. 먼저, 영문의 MTEBI를 국문으로 번역하고, 번역한 것을 다수의 수학교사 교육자가 철저하게 검토하였다. 그다음, 506명의 예비 초등교사 표본에서 정규성, 신뢰도, 타당도 등의 통계적 검정을 실시하였다. 그 결과, 한글판 MTEBI의 하위척도인 PMTE와 MTOE의 알파계수가 각각 .836과 .705이었다. 이로써 한글판 MTEBI가 한국에서 효능감 연구에 사용할 수 있을 만큼 믿을 수 있고 문항 구성이 타당함을 입증하였다. 나아가 본 연구에서 제시된 영문판을 바탕으로 한국과 교육에 대한 전통과 문화가 비슷한 이웃 문화에서도 효능감 연구가 일어나기를 기대한다.

The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.

In nuclear power plants, nondestructive examinations(NDE) plays an important role in ensuring the integrity and reliability operation. As the number of plants and operational time increased, manual handling of voluminous data associated with PSI/ISI(preservice/inservice inspection) could result in many errors or mistakes in writing the examination plan or other reports. Several new approaches to process the data have been attempted and DBMS(Data Base Management System) has been well known concept with a faster and more accurate data processing. This paper proposes an application program, called NDTSYS designed with DBMS in micro computer. The program could be used for a tool to add new records to a data base, change existing records, delete records and request reports with the data base. It would be helpful to the user who manage the PSI/ISI data with minimal time and effort.

The purpose of this study was to examine teacher's perception, practices about the multicultural education. The subjects were 382 kindergarten teachers in G province. Kim A Young(1996)'s questionnaire which is modified and improved after preliminary research was used to measure teacher's perception and practices about the multicultural education. The data were analyzed by the descriptive statistics, t-test, one-way ANOVA, Scheffe test. The results of this study were as follows. First, Kindergarten teacher's perception about multicultural education were significantly different by teacher's teaching careers, teacher's kindergarten types, children's age, learning experience in preservice curriculum. Second, Kindergarten teacher's practices about multicultural education were significantly different by teacher's teaching careers and kindergarten types.

The purposes of this research were as follows : (1) to investigate the effectiveness of the program for elementary preservice teachers, which was designed to develop postmodern views of science and constructivist views of teaming and teaching and (2) to find out the relation between students' learning approaches and their beliefs about science and school science. One hundred and forty three students enrolled in Science Education 11 in the University of Education participaled in the study. Students' beliefs of science and school science was not changed after treatment of the program. But they showed postmodern views of science and school science in comparison with the science teacher. Additionally the results showed that meaningful learners showed the constructivist view about school science as compared with the rote learners.
