본 연구는 유아교육기관에서 이루어지고 있는 자유선택활동에 대하여 알아보기 위하여 유아교육기관 만3, 4, 5세총 50학급에서 한 달간 작성된 일일교육계획안 1000개를 분석하였다. 이를 위하여 실내·외 자유선택활동의 운영여부, 운영시간, 흥미 영역별 활동 빈도 등을 분석하였다. 연구결과는 다음과 같다. (1) 연구대상 유아교육기관중 실내자유선택활동은 88%, 실외자유선택활동은 48%의 기관에서 운영하고 있었다. (2) 실내자유선택활동의 평균 운영 시간은 72.5분, 실외자유선택활동의 평균 운영 시간은 46.67분으로 나타났다. (3) 흥미영역 별 활동 빈도는 언어 영역이 가장 많았으며 수·조작, 미술, 쌓기, 과학, 역할, 음률 영역 순이었다. (4) 자유선택활동의 운영시간과 흥미영역 별 활동 빈도에서 연령별, 발달수준별 차이는 나타나지 않았다. The purpose of this study was to examine certain aspects of free-choice activities in Kindergarten and Child Care Center. In order to examine the mentioned above, management hours of in-out door free choice activities, and frequency of activities of interest center in 1,000 daily lesson plans written by 50 teachers in charge of 3, 4, 5-year-old classes were analyzed. The results of the analysis were as follows: 1) About 88% of the participants were managed in-door free choice activities, while 48% said they were managed out-door free choice activities. 2) The hours of management were each 72.5 minutes and 46.7minutes in-out door free choice activities. 3) The order of activity frequency in interest center is language, math-manipulative, block, science, role play, and music & movement center. 4) The hours of management and frequency of activities in interest center did not seem to consider children``s age difference and developmental level.

Thermo-acoustic waves can be thermally generated in a compressible fluid by rapid heating and cooling, chemical reaction near the boundary walls. These mechanism are very important in the space environment which are not exist natural convection and at the critical point of heat transfer of fluids.<br/> In this study, the transmission characteristics of thermo-acoustic waves in a air filled confined domain with rapid wall heating are studied numerically. The governing equations are discretized using control volume method, and solved using SIMPLE algorithm and first-order upwind scheme. For the perpose of stable solution time step were considered as t = I×10^-8 order, and grids are 100× 1000.<br/> Results showed that temperature and pressure of fluid near the boundary wall surface subjected to a rapid heating was increased abruptly, and the induced thermo-acoustic wave propagates through the fluid until it decays due to viscous and heat dissipation. Pressure wave have sharp front shape and decreasing long tail.

Recently global regulations on environment pollution and green house gases due to conventional energy consumption have been reinforced. So in the present study feasibility investigation on the solar assisted heating and hot water supply system for apartment houses were carried out by the review of service facility and heat load pattern of it, also operation and design of a small sized experimental simulator was performed.<br/> The experimental results showed that the mean collector efficiency was about 42% at sunny day in the heating season, and discharging efficiency of storage tank was 80~85%. And this hybrid system showed an energy savings of 27 ~ 48% compared to a typical gas boiler system in the case of artificial load pattern of hot water based on measurement data of apartment houses. Through the feasibility study, we found that the hybrid system can be applied to apartment houses for the energy savings and reduction of green house gases.

Purpose: The purpose of this study was to identify clinical decision making pattern of pediatric nurses and analyze how it shows the differences in types of decision making pattern by nurses characters. Methods: A self-administered questionnaire was used to pediatric nurses of 4 general hospitals in Seoul from February 2004 to April 2004. The data of 251 nurses was analyzed by varimax rotation factor analysis, t-test, and ANOVA. Results: 6 decision making patterns were identified: Individual Patient-oriented, Pattern-oriented Intuitive, Typical Nursing Knowledge-oriented, Nursing Model-oriented, Medical Knowledge-oriented, and Patient-Family-Nurse Collaborative. Individual Patient- oriented, Pattern-oriented Intuitive, Typical Nursing Knowledge-oriented, and Nursing Model-oriented decision making pattern got meaningful differences in age, marital status, total number of years in nursing practice, and number of years in pediatric nursing practice. Conclusion: We expect the result of this study can be applied for promotion of understanding the decision making of nurses that occurs in pediatric nursing practice and also can be used as foundation data for development and expansion of pediatric nursing practice.

본 연구의 목적은 예비보육교사의 자아개념, 전공이해도, 보육교사자질에 대한 인식을 살펴보고, 자아개념, 전공이해도, 보육교사자질 인식이 상호 어떠한 관계에 있는지를 알아보는데 있다. 연구를 위하여 경기도에 위치한 전문대학의 아동보육과 1학년과 2학년 학생 183명을 대상으로 설문지를 배포하였다. 수집된 자료는 SPSS 프로그램을 이용하여 평균과 표준편차, 독립표본 t검증, 변인간 pearson의 적률상관계수 산출, 단계적 다중회귀분석방법으로 분석되었다. 연구결과, 1) 예비보육교사의 자아개념, 전공이해도, 보육교사자질에 대한 인식은 평균이상으로 비교적 높게 나타났다. 2) 예비보육교사의 자아개념과 보육교사 자질은 강한 상관관계를 가지고 있으며, 1학년과 2학년 모두 예비보육교사의 자아개념과 전공이해도, 보육교사 자질과 전공이해도는 유의한 상관관계가 나타나지 않았다. 3) 예비보육교사의 자아개념은 보육교사자질에 대한 인식에 영향을 미쳤으나 전공이해도는 보육교사 자질에 대한 인식에 영향을 미치지 않는 것으로 나타났다. 본 연구결과는 보육교사의 기본 자질을 갖춘 예비보육교사 양성을 위한 교육과정 개발에 기초자료로 활용될 수 있을 것이다. The purpose of this study was to investigate the pre-service edu-care teachers’ self-concept, understanding for major knowledge, perception of the quality of edu-care teachers. For this purpose, this study sampled 183 college students in Gyeonggi Province and conducted the questionnaire survey. The data were analyzed by SPSS program. The results of this study were as following. First, the pre-service edu-care teachers’ self-concept, understanding for major knowledge, perception of the quality of edu-care teachers appeared relatively high. Second, the pre-service edu-care teaches’ self-concept and perception of the quality of edu-care teachers had strong correlation. But there was no significant correlation to the pre-service edu-care teachers’ self-concept, understanding for major knowledge and perception of the quality of edu-care teachers between first year college students and second year college students. Third, the pre-service edu-care teachers’ self-concept affect perception of the quality of edu-care teachers, but the pre-service edu-care teachers’ understanding for major knowledge did not affect the perception of the quality of edu-care teachers. These results would be used the basic date to develop an effective curriculum for the pre-service edu-care teachers.

The objective of the present study is to investigate the load delivery characteristics of a hybrid-renewable energy system with geothermal and solar heat sources for hot water, heating and cooling of a residential house in Korea. The hybrid energy system consists of ground source heat pump of 2 RT for cooling with a 150 m vertical U-bend ground heat exchanger, solar collectors of 4.8 m2 and gas fired backup boiler. The averaged coefficient of performance of geothermal module during cooling and heating seasons are evaluated as about 4.5 and 3.8, respectively.
