The purpose of this study was to analyze system thinking revealed in science teachers' teaching practices of middle school astronomy classes. Astronomy lessons were video-taped from four eighth grade science teachers. The video recordings were all transcribed and analyzed by employing a framework for systems thinking analysis after modifying an existing frame of hierarchial structure used in relevant previous studies. In addition, four participants were interviewed in order to uncover their orientation toward teaching using video stimulated recall method. Findings are as follows: All participating teachers were not able to employ the four levels of system thinking appropriately and only utilized the low level of systems thinking. They also demonstrated teacher-centered practices for employing system thinking despite their student-centered orientation toward teaching. The main reason for these results may be that teachers focused more on spatial thinking, than on system thinking as well as the lack of teacher's knowledge about the content and formative assessment of non-earth science teachers. Implications on how to effectively employ the system thinking in astronomy class are discussed in this paper.

This study investigates the practitioners' perception of Landscape Education in the universities in order to satisfy the demands of the rapidly changing industry. The survey was conducted for 257 practitioners to analyze the overall perception of Landscape Education, the importance and utilization of each course in universities, and the importance and utilization of each landscape process step. The overall perception of Landscape Education was slightly negative, and more practical education was demanded to improve the students' adaptability on the job. Practitioners suggested that universities should teach more practical expertise and related fields. They re-educated deficient aspects such as practical skills, computer techniques and legislational knowledge through the new employee training. The survey also showed that professors should be most responsible for a better education; however, students and practitioners have to endeavor together. According to the findings, planting design, landscape design, landscape materials, landscape planning and landscape construction as well as management were important. They are also considered as practical courses. However, practitioners perceived that university education was not sufficient for the constructional process. This means that Landscape Education in the universities has been more focused on planning and design. Because the universities are essentially for the research and study, changing the curriculum as practitioners suggested is not necessary. Nevertheless, it suggests for more practical education and balanced curriculum including construction and management that should be seriously considered. This study was focused on the practitioners' perception. Many of the respondents were from Seoul metropolitan area, therefore, it's hard to generalize the findings. A further study should be considered that would include instructors as well as students.

Although the recent interest in and favor for natural burial has increased, there are still few who choose it as a funeral. The purpose of the study is to supply necessary information to promote the choice of natural burial. For this a survey of 430 students and residents was conducted in Daejeon. The result of the research is as follows. First, there is a significant difference in use intention of natural burial by age and religion. People under the age of 30 and Catholic believers recorded the highest score in use intention of natural burial. Second, there was a significant difference in information on natural burial by age or religion, in religion and philosophy by age, in physical environment by sex or age, and in conservation by sex or age. In general, the lower the age, the higher the positive perception of natural burial was. While females had a more positive perception of physical environment than males, males had a more positive perception of conservation than females. All sub factors of the perception of natural burial such as information on natural burial, funeral style, religion and philosophy, physical environment and conservation had a significant and positive effect on its use intention. However, ratio skew showed that religion and philosophy had the strongest effect on use intention of natural burial, followed by funeral style, physical environment, conservation, and information on natural burial.

We investigated the prevalence of eating disorder risk group and its relationship with Physique status and eating behavior among high school students in Daejeon. In May - June 2002, 350 students were sampled from 6 high schools in Daejeon by multi-stage cluster sampling and assessed with self-completing questionnaires. We used the Korean version of Eating Attitude test(EAT-26) to screen eating disorder risk group. and other instruments to screen physique status and eating behavior. The response rate was 91%(total 320) and numbers of female students were 167(52.2%) and male students were 153(47.8%). Average age was 16.0${\pm}$0.35 years, and average body-mass index(BMI) and PIBW(Percent Ideal Body Weight) were 20.9${\pm}$3.3 Kg/m2 and 102${\pm}$4.2% in male students, 20.2${\pm}$3.7 Kg/m2 and 98${\pm}$7.2% in female students(p<0.0001). Over 50% of the subjects were dissatisfied with their body shape; the degree of dissatisfaction with body shape was higher in those who believed themselves to be fat. Mean score of EAT-26 was higher in female students (10.78${\pm}$7.36) than male students(6.07${\pm}$4.39)(p<0.0001). The prevalence of high risk eating disorder group was 2.6% in male students, 11.4% in female students(p<0.0001). Eating behavior was better in female students than male(p<0.0001). Eating behavior was significantly higher in eating disorder risk group in both sex. Therefore eating disorder symptomatology was highly prevalent among high school students in Daejeon. And this symptomatology has a more close relationship with physique status and eating behavior in female students.

The purpose of this study was to develop the equation of $\dot{V}O_{2max}$ by $sub_{max}imal$ PACER method for obese middle school boys. For this, $_{max}$imal test using Bruce protocol in lab was performed and then PACER $_{max}imal$ test with portable $\dot{V}O_{2max}$ equipment. To decide the level of submaximal test, during PACER with portable equipment, we found the section in which target hreat rate(over 75%$HR_{max}$) and then per section(75%,80%,85%,90%,95%) metabolic responses were recorded, with which we analyzed multiple regression by stepwise method. Model 1(at 90%$HR_{max}$): $\dot{V}O_{2max}$(ml/kg/min) = 142.721-0.275(repetition)-0.48(HR)+0.177(weight)-1.536(age)[%error 3.90ml/kg/min; performance until 2 stage(13 repetition)]. Model 2(at 95%$HR_{max}$): $\dot{V}O_{2max}$(ml/kg/min) = 182.851-0.103(repetition)-0.744(HR)+0.186(weight)-0.324(age)[%error 4.51ml/kg/min; performance until 3 stage(25 repetitions)]. estimated $\dot{V}O_{2max}$ from Model 1 was different about $3.25{\pm}6.32ml/kg/min$(%error=6.84%), otherwise model 2 was $3.16{\pm}4.54ml/kg/min$(%error=5.75%). considering %HRmax, as the submaximal test model 1 might be fit more than model 2 for obese middle school boys.

To assess the quality of commercial Sujongkwa, we compared physicochemical and sensory characteristics of commercial Sujongkwa with home-made one. Two different brands of Sujongkwa and home-made one were analyzed for physicochemical (sugar content, pH, acidity, color, viscosity, transparency) and sensory characteristics (7-point scoring test, 15 experienced panel members). Separately, we assessed the opinion of food and nutrition specialists about the commercial Sujongkwa. Questionnaires were hand delivered to 530 subjects consisted of university students and faculties of Department of Food and Nutrition at 8 cities (Seoul, Incheon, Yongin, Daejon, Chungju, Daegu, Kwangju, Busan) in Korea and the complete data of 328 subjects were statistically analyzed using SPSS Propam for Window (mean, ANOVA, $\chi$$^2$). The questionnaires were consisted of sociodemographics, frequency and occasion of purchasing, opinion of quality and improvement points. Both commercial Sujongkwas were lower in sugar content, transparency, color(L and b value) and viscosity, and commercial brand B was higher in pH and color a value than home-made one. Also, among sensory characteristics, over-all preference and color for brand B were significantly higher than those for brand A and home-made one (p<0.05). Especially, the scores of over-all preference were 1.9 for brand A, 5.7 for brand B, and 4.9 for home-made Sujongkwa. Points to be improved for commercial Sujongkwa were in order of sweetness (33.0%), pungency (24.2%), dried persimmon (19.1%).
