Effect of raising types and environmental conditions on the infection of Toxoplasma in the swine, the cat and the man were studied in Cheju Island from Sept. 1987 to Aug. 1988. Blood samples were taken from 214 conventionally raised swine in 6 villages and 506 swine raised in swine specialized farms, 122 cats raised under free moving or restraned conditions in 8 locations, 113 butchers, and 210 villagers. Toxoplasma antibody values of the blood sera were determined using the enzymelinked immunosorbent assay (ELISA). The eating type of viscera was also investigated by using questionaires 1. When ELISA method was used, the percentage of Toxoplasma infected swine among the conventionally raised and of those raised in swine specialized farms were 60.7% and 21. 390, respectively. The respective mean of antibody values (${\pm}SD$) were 0.589 (${\pm}0.310$) and 0.385 (${\pm}0.237$) and differed very significantly (p<0.01). A significant difference was also found in antibody values among 6 villages (p<0.05). 2. The mean infection percentage of toxoplasma in the cat was 38.2%. the infection percentage for cats raised under free-moving and re~;trained condition were 37.0% and 38.2% respectively. The respective antibody values(${\pm}SD$) for toxoplasma were 0.600(${\pm}0.614$) and 0.637 (0.645), and did not difference significantly. 3. The infection percentage of toxoplasma in villagers and butchers were 26.2 and 38.3% respectively. The respective antibody values (SD) for toxoplasma were 0.429(${\pm}0.195$) and 0.341 (${\pm}0.236$), and differed very significantly (p<0.01). There were also highly significant differences Pyo-sun and other village (p<0.01). 4. Analysis of the questionaires showed that 26.0% of 392 villages eated liver and some villagers eated other viscera.

The following study was done to investigate foodservice management practice. Total subjects were 18 foodservices in social welfare facilities in Seoul. Among studied facilities, nine were the welfare facilities for children, five were the welfare facilities for elderly, two were the welfare facilities for a mentally and physically disabled person and the remaining two were vagabond care facilities. Methods used were mainly questionaires. These questionaires were answered by manager and interviews were also done for a same person. Equipments were evaluated by investigators using the evaluation form. The results of the study were summarized as follows. Number of cooks and assistant cooks among employee in foodservice establishment were about 2-6 persons. One dietitian is stationed in 2 places among 18 places. Food purchasing and menu plannings were mainly practiced by manager, secretary and other personnels, in more than 50% of social welfare facilities. The type of the menu in most facilities was the set menu. The period of turn over for cycle menu was a week in 50% of facilities. Seventy seven point eight percentage of the welfare facilities were used the weekly or monthly cycle. For the food preparation, there was almost no place using standard recipes. Foodstuffs were purchased in local market. Moreover, the preference test of served foods were done for residence of each facilities. But it was not applicated effectively. Conditions of most equipments in the kitchen were defective specially in dishwashing and sterilization step.

This study analyzed the problem associated with inquiry centered science education and formulated some improvement Strategies for inquiry learning in the standard Korean high school course. In order to attain the goals of questionaire survey methods were used. To examine the current status of biology education, seperate questionaires were developed through an educational research and development procedure used for tearchers and student. The questionaires were developed to ask about instruction and evaluation methods, the level of inquiry learing and abstacles to it. Here are some of our results: 1) Biology instruction and learning is more knowledge-orinted than inquiry-orinted, 2) Inquiry approach in science teaching is hard to be applied because of crowed classroom conditions. 3) The material is too broad in range and too difficult in content. There is virtually nothing that can be related to everyday life. The material focusing on inquiry activities is unsatisfactorily selected and organized. 4) Effective methods of inquiry-based instruction and evaluation are not available. 5) Biology teachers are burdened with too many class hour a week and too many varieties of additional works. 6) 91.1% of biology teachers and 90.3% of students recognize that lab and field works are needed to enhance inquiry learning. However, in reality, such inquiry activities are lacking. 7) 73.3% of schools have no lab assistants. 8) The university entrance examination is the greatest factor against inquiry learning. 9) There are very few chances of in-service education for biology teachers to learn more about biology curriculum and science education theory.

The purpose of this study was to investigate the computer-naive children's preconceptions of computer concept, anxieties for computer, the changes in preconceptions and anxieties by computer literacy teaching, and the effect of CASI(Computer Assisted Science Instruction) on the science achievement. For this study, 42 5th graders were sampled. They were divided into two groups, experimental group(male:10, female:11) and control group(male:12, female:9). Each group was randomly assigned in the elementary school. Preconceptions about computer were examined by individual interview. Computer anxiety score was measured by questionaires. The questionaires developed in this study consisted of total 21 items measured by Chronbach ${\alpha}$ (0.93) and Total Item Correlationtp(p=0.01, r = $0.40{\sim}0.72$). Computer literacy curriculum based on children's preconceptions was developed and then was treated for experimental group as a computer literacy course. Preconceptions of computer, computer anxiety, and CASI achievements were compared between experimental group and control group in pre and post test. The results of this study are as follows; 1) children's preconceptions of computer showed various non-scientific concepts as animism and obvious visiual thinking. 2) children's misconceptions and anxieties about computer did not show significant differences in terms of learning experience of computer. 3) computer literacy had an effect on eliminating children's misconception about computer. 4) computer literacy had an effect on diminishing children's computer anxiety. 5) children's misconceptions and anxieties about computer showed significant inter-correlation. 6) children's misconceptions and anxieties about computer were appeared negative effect on CASI achievements. As the results, children's misconception and anxieties about computer had an effect on CASI acheivements. Therefore before performing CASI, more systematic computer literacy might be taught in formal education.

In 1987 Ministry of Education published the 5th-revised version of curriculm, the main goal of which is to improve science and culture as well as to educate the students who are able to actively adapt to the 21st century's society. Howerver, the revised curriculum neglects the problems associated with the nature of and localized characteristics of science education. Therefore this research had its main objective to survey and analyze the status of science education of secondary schools in Kangwon Province and, based on the results, to develop the teaching/learning materials appropriate for science education in this province. This research is 3d-Year project and this paper is about its first year research results. The first year's main objective is to investigate and analyze the status of middle school science education, focusing on the curricular operation, science teachers, and lavoratory facilities and instruments. This research used the survey methods. The questionaires were sent to all the middle schools the number of which is 163, and 162 schools of which returned the survey questionaires. Based on the analyses of the data following conclusions were drawn. The average class size is 48.8 students. Almost all of the middle schools alocate the science class hours per week of 4,3,4 hours to first, second, third grade, respectively. However, the greater part of science teachers want 5,4,5 hours of science classes a week. Total number of science teachers exeeds the number actually needed, implicating that many science teachers are teaching non-major subjects. The lavoratory facilities and instruments are not sufficiently provided for lavoratory-based science education. Along with these conclusinons suggestions for better science educations are recommanded. Among the suggestions two are highly emphasized.They are: to increase science class hours; to use field lavoratory substituting for school lavoratory.

The status of facilities, management for the experiment, practices, teaching methods in middle schools have been investigated. The present status and reasonable management of the middle school science education have been grasped from the questionaires. To do this 125 secondary science teachers, 1,745 students and 70 principals of schools in Korea are administered questionaires of Science Education Reserch Institute of Kyungpook National University(1996). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the middle school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper

It is necessary that children's actual activities in the playgrounds should be analyzed for the study on the children's playgrounds. The purpose of this study is to establish the design principles for the improvement of the children\`s playgrounds in apartment complex by means of the various methods ; behavior mapping, questionaires and photo simulations. For the purpose of data collection, children are divided into three groups-infants(0 to 4 years), young children(pre ; 5 to 8 years, post ; 9 to 11 years), teenagers(7.2 to 14 years). The study results are as follows; 1) Analysis of behavior mapping : (a) Approximately 70 percent of the children observed stayed in the playground less than 20 minutes. (b) Playing time for each play apparatus was less than 5 minutes. (c) As a result of the observation, the duration time in the attic was 1 hour or more (d) The swing was the most frequently used apparatus as children's first and last choice. (e) Most of the users were young children(46.5%). 2) Analysis of questionaires : (a) Children considered that the existing playgrounds were lack of shadows and the play apparatuses are not interesting. (b) They felt danger and crowding at the multi-used wooden apparatus. 3) Suggestions for the playground design : It is necessary that the playgrounds are divided into the infants, the young children's and the teenagers'playground. (a) The infants'playground needs about 50 square meters and needs to be located in the apartment court. (b) The young children's playground needs about 330 to 660 square meters and needs to be located adjacent to the pedestrian road. (c) The teenagers'playground needs about 660 to 1000 square meters, which is needed for various ball games.

This study is practically focussed on the derivation of the formula of the reach of the catchment of urban community parks and the reached distance to the parks. The hypotheses for the formula are as follows. a. The catchment of urban community parks can be dependent on the quantitative characteristics that urban community parks have substanial factors : the potential residential population of the proximate community to a park, park visitor's day and mean usetime per year. b. The distance to the urban park is a decided variable which can be percieved quantitatively by the researchers among the exogenous variables concerned with the mean usetime of the urban community park. The data for the variables were collected from the statistics, and the surveys for 9 parks of 4cities(Seoul, Chong-ju, Su-Won, Chon-an) in Korea, which were divided into on-site samples and off-site ones in 1991. The data were collected by questionaire surveys. A total of 548 questionaires of off-site surveys were completed by the residents in the enticing area of the parks. A total of 1053 questionaires of on-site surveys were completed by the visitors of the parks. The research could attempt to derive a formula, which was concerned with the reach of the catchment of urban community parks and the reached distance to the parks. It is testified(R2>0.8) that the numbers of mean usetime per year should be related with the reached distance from a visitor's house to a proximate park. The formula is analogized with an exponential function: {{{{ Mean Usetime per year=f(x)=Ae-BK+Ce-DK ear, X is reached distance from a visitor's house to a proximate park. A,B,C and D are parameters. And, the differences of the reach of the catchment of the parks are not only testified with resulting from the differences of the exogenous variables of qualitative characteristics differences of the parks, but also divided separately into spatial ranges. This formula will be able to anticipate the visitor's numbers of a planned urban community park.

The objective of this study is to collect the opinions on the present condition and the improvement directions of urban health centers from and to make a comparison. Samples were drawn from the various sources of a district in seoul. 53 persons involved in district health's administration(the Members of a District Parliament, the senior officials of a District office, village chief) and 84 health center workers were surveyed with anonymous postal questionaires and 427 district private medical personnels with postal questionaires and 625 users of a health center with direct questionaires, from November 18 to 25, 1996. Additionally, 12,151 households were surveyed with self-reported questionaires including priorities on special district health services of health center, from September 1 to 7, 1996. The major findings were as follows : 1) Although the persons involved in district health administration tend to put lower priority on health service over other community activities, they well acknowledged the importance of health center. But health center workers strongly acknowledged the importance of both health service and heath center. 2) As to the level of human resoureces, equipments and ammenities of Health Center commpared with private medical institute, the persons involved in district health's administration and health center workers responded that health center was higher in following order : 54.9%, 41.6%, 36.5% and 88.0%, 80.7%, 44.1%. 3) Concerning the priorities of health center's improvement, the persons involved in district health's administration replied in the order of reinforcement of proffesional health workers (43.3%), improvement of equipments and ammenities(28.3%), and the health center workers replied in the order of reconstruction of organization(24.1%), public health education and promotion(22.8%), reinforcement of proffesional health workers(21.0%). 4) Both the persons involved in district health's administration and health center workers replied that Ministry Health and Welfare, District office, health center were essential as the most critical organizations in the activation of Health Center's Function. 5) Persons involved in district health's administration and health center workers chose, as the most important health center's Function, medical treatment and prevention of infectious disease, and prevention of acute and chrone disease control and special district health service, respectively. Both Groups replied that fammily planning and parasite control are no longer in need. 6) As the future health service requiring reinforcement, every human resources parties considered health conselling, health line, sex education as the most imortant elements in public health education. Concerning the reinforement of other health services such as medical checkup and visiting nurses, every human resources parties showed more than 80% approval rate, but for oriental medical care service, the private medical personels showed relatively low approval rate(52.9%). Therefore the planning for reinforcement of health center's function requires the reflection of human resources party's opinion and the implication of system which can control and combine the differences in party's opinions.

The purpose of this study were to identify consumer educational needs of elementary school teachers and to analyze the factors affecting it. The data for the analysis were collected by structured questionaires and consisted of 253 elementary school teachers living in Taegu city. The descriptive statistics, t-test and one way ANOVA with Scheffee test were used to analyse the data. The following is summary of major findings. 1. Teachers though that the topics related to environment protection and consumption value were the most important in the consumer education of elementary school among the five topics. These topics were also very emphasized in the current elementary school curriculum. The topics related to consumer citizenship and buying were ranked as the highest scores of the educational needs of teachers. Therefore these topics should be emphasized in the future consumer education curriculum of elementary school. 2. The age, sex and period of educational career of teacher. teacher’s perception of student’s and teacher’s interests about consumer education and teacher’s wants of on-the job traing were found to be the factors affecting consumer educational needs of elementary teachers.
