A dynamic simulation model was developed to analyse the transient characteristics of a multi-inverter heat pump. The programs included a basic air conditioning system such as a evaporator, condenser, compressor, linear electronic expansion valve (LEV) and by-pass circuit. The theoretical model was derived from mass conservation and energy conservation equations to predict the performance of the multi-inverter heat pump at various operating conditions. Calculated results were compared with the values obtained from the experiments at different operation frequencies of compressor, area of the LEV and configuration of indoor units operation. The results of the simulation model showed a good agreement with the experimental ones, so that the model could be used as an efficient tool for thermodynamic design and control factor design of air-conditioners.

The purposes of this study were to investigate ecotourism goals which are providing educational tourism, generating environmental conservation, and residents' economic benefits based on the 7th Muju Firefly festival. The sample was 243 visitors from August 23rd to 30th, 2003. The results were as follows: First, visitors showed high satisfaction for the educational tourism program. Experiencing educational 'Mysterious Firefly Field Trips' contributed to the tourists' educational satisfaction. It was found that these experience programs were very popular. Second, residents' and domestic visitors' satisfaction was high with 5.50 on Likert 7 points concerning environmental conservation. Third, foreigners showed high satisfaction for visiting tourism sites and understanding regional culture in terms of understanding region and economic benefits. The average economic effect was decreased compared to 2002. So there should be more diverse strategy to increase economic effect. Also more festival related products, diverse and unique foods and beverages based on regional products should be developed.

The Ministry of Environment supports environmental education mainly in two ways ; one is by supporting schools engaged in environment conservation model school and the other is by extending grants for experiential environmental education programs. This research aims to evaluate the current status of grant for experiential environmental education programs while proposing possible improvement for constructive and continuing development of the support measures. Grant for experiential environmental education programs is divided into two areas of grant for schools and grant for community-based civil organizations. The diagnosis and evaluation were conducted in terms of 7 areas, such as time, facilities, programs, manpower (professional expertise), operation, administrative and financial support mechanism and others. Research process involved the review of previous studies in 2001 and 2003, comparison of the grant program with other grants in and out of Korea for environment education, and the following areas considered when identifying improvement options: i) Overall review of objectives and operations, ii) expansion supports programs oriented problem solving as well as those focused ecological sensitivity, iii) change from expendable, one-time program to productive, continuous program, iv) link to social changes and issues, v) principles for operation and evaluation, vi) criteria and methods for program selection and evaluation, and vii) improving operation system. Based on review and the overall evaluation on the experiential environmental education program grant, the recommendation for improving operation system were provided, which included stages of passive improvement, active improvement and building infrastructure for environment education, and building capacity of the members related in the initiatives.

The purpose of the study is to examine the effects of Gifted Education Isnstitute of Korea (GEIK) programs for gifted children especially in the areas of reasoning skills and creativity, thereby proving the effectiveness of the program. The subjects are 136 (103 boys and 33 girls) fourth, fifth, and sixth grade gifted children, who have participated in GEIK programs for more than six moths. They were stratified by the length of participation in GEIK programs. Ninety four children have participated for more than one year. Forty-two children have participated for less than one year. Both groups are rather homogeneous in IQ scores and school achievement levels at the time of enterance into GEIK programs. Both a Group Assessment of Logical Thinking (GAIT) and a Creativity test were used for the study on reasoning skills and creativity. GALT, developed by V. Roadranka, R. H. Yeany and M. J. Padilla in 1983, consists of 12 questions. It is classified into six subscales: conservation, proportional reasoning, controlling variables, provability reasoning, correlational reasoning, and combinatorial reasoning. The reliability of this test is .85. This test recommends to classify the stages of child development as follows according to the total test score. 0-4 point: Concrete Stage, 5-7 points: Transitional Stage, and 8 and above points: Formal stage. The Creativity Test was developed by Y. Lee and W. Chung (1971). It consists of four components: fluency, flexibility, originality, and openness. Only both fluency and openness were used in this study. In order to analyze data, T-Test, Intercorrelational Analyses, ANOVA, and Nultiple Regression were used. Followings are the results deduced from the above analoyses of the data. First, 43.48% of the subjects were on Concrete Stage, 36.78% were on the Transitional Stage, and 19.86% were on the Formal Stage in the developmental level classified by Piaget. Second, the students who have participated in GEIK programs more than one year acquired significantly higher score in GALT than the students who have participated in GEIK programs less than one year. Third, boys showed higher score in GALT than girls did. Fourth, there were statistically significant intercorrelations between six subscales of GALT. Fifth, the students who have participated in GEIK programs more than one year acquired significantly higher score in openness of creativity test than the students who have participated in GEIK programs less than one year. There were no significant differences in openness of creativity test between boys and girls. Sixth, the students who have participated in GEIK programs more than one year acquired significantly higher score in fluency of creativity test than the students who have participated in GEIK programs less than one year. Girls showed higher score in fluency of creativity test than boys did. Seventh, the students who acquired higher score in GALT showed higher score in both openness and fluency of creativity test. Followings are the conclusions deduced form the above results. First, the developmental level of reasoning skills of the fourth grade students participationg in GEIK programs is the same as that of 7th grade of normal Korean students and the same as those of 10th grade of U.S.A. and Philipoine students. Second, the GEIK programs are effective in improving reasoning skills. Third, the GEIK programs are effective in improving creativity. Fouth, reasoning skills and creativity can be improved by well planned programs. In conclusion, this study suggests that beyond reasoning skills and creativity, other areas such as areas in science skills, mathmatical skills, or verbal skills, etc., should be studied in the future.

Many simulation programs included intake and exhaust system on diesel engines have been developed. However, existing programs using 1-D numerical analytic methods in manifold gas flow by the method of characteristics have some problems to be solved.. Especially to optimzing the engine system, a simulation program which had more efficiency and accuracy is required newly. In this paper, a improved method for application limit and efficiency as well as mass conservation named constant mesh explicit method of characteristic was described. And some calculation results by this method were compared with experimental results and orther calculation results. Also, it was confirmed that the results by the proposed method were more agreed with experimental results.

This paper reviews the meat-type chicken breeding with local breeds in China. The quality chickens are defined as purebred final products of local breeds, and semi-quality chickens as crossbreds of local breeds with specialized broiler (sire or dam) lines from western breeding organizations. The present status of the chicken production and the market in China, in comparison with the western countries, is reviewed, indicating that there is large market demand for (semi-) quality chickens in the present and future China. Breeding for (semi-) quality chickens emphasizes the sensory quality of chicken meat. The present status of breeding for (semi-) quality chickens with the local breeds is illustrated, including breeding goals and the existing breeding programs. The potential role of local breeds in breeding programs in China is discussed in relation to both providing higher quality (than commercial hybrid broilers) of chicken meat for the local market and meeting the objectives of genetic resource conservation. Besides, further research topics on breeding for (semi-) quality chickens are suggested.
