The purpose of this study was to examine the efficacy of child care and the education and the influence of job-stress on job-satisfaction of child care and education teachers. 172 child care and education teachers were chosen from 40 child care centers located in Incheon, Gyeonggido, and Seoul. Data were collected using the efficacy of child care and education index, the job-stress instrument, and the job-satisfaction instrument, and were analyzed using t-test, one-way ANOVA(Duncan test), correlation analysis and multiple regression analysis. There were significant differences in child care and education teacher's job-satisfaction according to the teacher-related variables, including the type of institution, the number of classes, the age of children, the education, the teaching experience, the income, the age of teacher, and the marital status of the teacher. Correlation analysis indicated that the teacher's efficacy of child care and education and the job-satisfaction had significant correlations, especially the satisfaction of job itself indicated high positive correlations. Job-stress and job-satisfaction of the child care and education teachers had significant negative correlations in all sub-variables, especially the stress from the working environment and the satisfaction of administration system indicated high negative correlations. It was also found that stress from the working environment, stress from the overload, stress from the peer relations, and the efficacy of child care and education were all significant predictors of the child care and education teacher's job-satisfaction.

Objectives: Study purpose was to investigate perception on diet, diet problems and related factors among young adult women using focus group interviews (FGI) based on the Social Cognitive Theory (SCT). Methods: Eight groups of FGI were conducted with 47 female undergraduate or graduate students. Guide for FGI included questions regarding perception on optimal diet, diet problems and cognitive, behavioral, and environmental factors of SCT. FGI were video, audio-taped, transcribed and analyzed by themes and sub-themes. Results: Subjects showed irregular eating habits (skipping breakfast, irregular meal time) and selection of unhealthy foods as the main diet problems. Regarding cognitive factors related to optimal diet, subjects mentioned positive outcome expectations (e.g., health promotion, skin health, improvement in eating habits, etc.) and negative outcome expectations (e.g., annoying, hungry, expensive, taste). Factors that promoted optimal diet were mainly received from information from mobile or internet and access to menu or recipes. Factors that prevented optimal diet included influence from friends, lack of time and cooking skills. Behavioral factors for optimal diet included behavioral capability regarding snacks, healthy eating and smart food selection. Subjects mentioned mass media (mobile, internet, TV) as the influential physical environment, and significant others (parents, friends, grandparents) as the influential social environment in optimal diet. For education topics, subjects wanted to learn about healthy meals, basic nutrition, disease and nutrition, and weight control. They wanted to learn those aspects by using mobile or internet, lectures (cooking classes), campaign and events. Conclusions: Study results might be used for planning education regarding optimal diet for young adult women. Education programs need to focus on increasing positive outcome expectations (e.g., health) and behavioral capability for healthy eating and food selection, reducing negative outcome expectations (e.g., cost, taste) and barriers, making supportive environments for optimal diet, and incorporating topics and methods found in this study.

The microbiological and chemical identification of antibiotic residues was attempted for livestock and seafood products including pork (n=34), beef (n=34), chicken (n=32), flatfish (n=37), armorclad rockfish (n=36), and sea bream (n=27). The meat (n=100) and seafood (n=100) samples were collected from 9 markets in 5 major Korean cities. Antibiotic substances were identified from the classes of tetracyclines, macrolides, penicillins, aminoglycosides, polyethers, peptides, sulfonamides, quinolones, chlorampenicols, and novobiocins using a microbiological assay, the Charm II test and high performance liquid chromatography (HPLC) with ultra violet (UV) and fluorescence detectors. The results showed that 2 tetracyclines (oxytetracycline and tetracycline) and 3 quinolones (ciprofloxacin, norfloxacin, and enrofloxacin) were detected in 4 samples of flatfish among all 100 seafood samples tested. No antibiotic residues were detected in the 100 livestock product samples tested. The amounts (min-max, mg/kg) of the residual antibiotics were as follows; tetracycline 0.78-0.85, oxytetracycline 0.49-0.74, ciprofloxacin 0.09-0.83, norfloxacin 0.01-0.21, enrofloxacin 0.12-2.98. These data indicate that the total detection rate of antibiotics in livestock and seafood products was approximately 2%.

The purpose of this study is to find out the effect of hypothesis formulations using abduction on science processing skills and the creative thinking activities. As the subject, 2 classes in the $6^{th}$ grade of B elementary school located in Busan were selected. Through the pre/post inspection design between experiment and comparison class, the units of science courses in the second semester of $6^{th}$ grade '1. A change in the weather' and '2. Various gases' were applied. The results were as follows: Firstly, the test on science processing skills showed that there was not statistic meaningful differences between the two groups. And, in the sub-parts, there was not statistic meaningful differences between the two groups. Secondly, it was observed that it would have a meaningful effect to improve the creative thinking activities of students who performed hypothesis formulation using abduction. Especially, through this, the experimental class gave a positive effect on the 'Fluency' and 'Elaboration', one of lower categories of the creative activities. The results of 'Flexibility' and 'Originality' in the experimental class were higher than those of students in the comparative class. However, according to statistical analysis, this result is meaningless. Thirdly, on the survey about the hypothesis formulation using abduction, many students thought that this learning method was very interesting and helpful to study science. In addition, it was observed that the ability to use abduct thinking was improved more than ever before.

Objectives : This study is aimed to evaluate the diagnostic value of Ryodoraku for traditional Korean medicine practice reported in the Korean literature. Methods : A search of seven Korean databases was performed up to May 2011 using the search term 'Ryodoraku(in Korean)'. All clinical studies on diagnostic Ryodoraku characteristics were included. Results : The search yielded 59 studies, of which 5 were considered suitable for this analysis. Four were observational studies. Only one was a controlled trial. Average Ryodoraku score(RS), mean values for each measure point, physiologic limit, number of Pyesaek and Gyeokcha, and pattern classification were used as references for the analysis. Correlations were observed between average RS and idiopathic Parkinson's disease, some sub-groups of respiratory disease, chronic low back pain, and menopause. Some mean values for measure points showed particularly high or low tendencies in patients with idiopathic Parkinson's disease, chronic low back pain, and menopause. Positive correlations were observed between the number of Pyesaek and H-Y stage in idiopathic Parkinson's disease and F2(肝) and the modified Kupperman's index with menopausal women. The four classes, organized based on Ryodoraku pattern, showed differences in various characteristics. Conclusions : Since only five studies met the experimental conditions, this evaluation of the diagnostic value of Ryodoraku in various situations is limited. Future studies should be conducted using various physiologic and pathologic situations.

The purpose of this study was to investigate the elementary students' views about lab-based science learning. For the purpose of this study, semi-structured interviews were conducted with thirty sixth grade students in 12 classes from two elementary schools located in Daegu City. The interview contents consisted of three major categories. The first category was related to attitude toward science lab, the second was related to lab-based science learning which had four sub-categories; recognizing lesson object, planning experiment, performing experiment, drawing conclusion in lab-based science learning in which the students had ordinary have views and expectations, and the last category was related to students' difficulties and something need to be improved in lab-based science learning. In-depth interviews were performed individually and the interviews were recorded. From the interviews, we found that students, in first category, do like lab-activities more than lectures or instruction-based activities in textbook. Students, in second category, wanted generally more discussion for their own activities rather than teacher's instruction and they wanted teacher' mediation conflicts within small groups and comments for students' experiment results. In the last, most of students had fears for some dangerous reagents and accidents. Based on the results, the study suggested that teacher need to give their students to autonomous discussion opportunities to design and interpret data through teacher' guided questions in inquiry steps, to produce some intimate atmosphere for active interaction in small groups, and to teach the safety education on some dangerous reagents.

The purpose of this study is to investigate the effects of the causal thinking activity of Let's Think Through Science(LTTS) program on causal thinking and science process skills of elementary school students. Four classes of 4th graders (N=119) from a elementary school were divided into the control and the experimental groups. Causal thinking activity of LTTS program was used with the experimental group, while the normal curriculum was conducted with the control group. Both groups were given a pre-post test on causal thinking abilities and science process skills. And the experimental group was given 15- item questionnaires analyzing of perception on LTTS program. This study revealed that causal thinking activity of the LTTS program were effective on the development of students' causal thinking abilities and science process skills. ANCOVA results revealed that the scores of causal thinking abilities for the experimental group significantly higher than those of the control group. In the sub-tests of the causal thinking abilities all categories were effective. And ANCOVA results of the science process skills were also effective. Science process elements of observation, recognizing of a problem were significantly higher. And elementary students preferred to the causal thinking activity of LTTS program so that it was interesting, useful, helpful to each other in studying science.

Teaching aids Robot Education, through early education and contests, is very commonly known to elementary school students, their parents and teacher. However, not only we do not have complete knowledge of how robot education for after school performs, but also we lack a proper management skills in educating new teachers and running a structured program. Thus, through this research, we would like to identify the problems in teacher's knowledge and how the robot education is running according to provinces, size of cities, public private school, and size of schools and provide proper and most effective way of teaching after school robot class. According to the result of this research of running 'Robot class' in different area, sub-areas and size of schools, there was a meaningful difference and the biggest problem in performance was the class organization. In addition, about the expectation through after school classes, the research showed that the teachers expect lower cost of private education and improvement in creativity the most.
