This study was conducted to gather basic data on the tasks and roles of nutrition teachers by analyzing the changes inwork importance, performance frequency, and organizational environment after dietitians were transposed to nutrition teachers. E-mail surveys were sent to 100 newly assigned nutrition teachers who previously served as dietitians in Gyeonggi province. A total of 72 teachers responded to the survey. The respondents were asked the importance and frequency of 9 work-related duties performed as a dietitian and nutrition teacher, respectively. They were also surveyed regarding their satisfaction perceptions for 5 organizational changes. The majority of respondents were 36 to 40 years old (48.6%) and had 10$\sim$20 years of work experience (58.3%). Significant differences were found for work importance after changing to the role of nutrition teacher (p<0.001). In addition, work performance frequency differences were found for the categories of nutrition education, nutrition counseling, and dietary guidance. These results were attributable to the differences in work importance and performance frequency by now being a nutrition teacher rather than a dietitian. The respondents had increased satisfaction levels after changing from dietitian to nutrition teacher (p<0.001) in terms of 'pride for change in work', 'satisfaction level for pay', and 'satisfaction level for change in the organizational environment'. In order for nutrition teachers to have effective work performance, 'personal capabilities' and 'school manager support' should be coordinated. Overall, the results of this study suggest that effective training programs should be developed for nutrition teachers they can effectively complete newly assigned work tasks.

Objectives : The aims of this study were to examine agreement between parent and teacher ratings of the Korean version Strengths and Difficulties Questionnaire (SDQ-Kr) for the children's psychopathology and to determine whether it is effective in diagnostics as the Korean version of Childhood Behavior Checklist (K-CBCL). Methods : SDQ-Kr and K-CBCL were completed by parents and teachers of 165 children aged 6-12 years. The clinical diagnosis was made by a child and adolescent psychiatrist who did not have knowledge of the outcome. Spearman's correlations were computed for associations between parents' and teachers' ratings on a subscale level. The Mann-Whitney U test was performed for the influence of child's age and sex on the results. Finally, AUC values were calculated for the diagnostic capacity and the difference between informants was tested using the z test. Results : High correlations were observed between parents' and teachers' SDQ-Kr on every scale. Parents were more sensitive to emotional symptoms of girls, while teachers appeared to be more responsive to externalized symptoms of boys, inattention-hyperactivity of young children, and emotional symptoms of seniors. Parents' SDQ-Kr demonstrated the highest prediction of attention-deficit hyperactivity disorder. Conclusion : Teachers' SDQ-Kr can be used in identification of child psychopathology when parents are absent or when their reliability is considered low.

A new method for the simultaneous determination of seven transition metal ions in water and food by microcolumn high-performance liquid chromatography has been developed. The lead, cadmium, mercury, nickel, cobalt, silver and tin ions were pre-column derivatized with tetra-(4-aminophenyl)-porphyrin ($T_4$-APP) to form the colored chelates which were then enriched by solid phase extraction with $C_{18}$ cartridge. The enrichment factor of 50 was achieved by eluted the retained chelates from the cartridge with tetrahydrofuran (THF). The chelates were separated on a ZORBAX Stable Bound microcolumn ($2.0{\times}50\;mm,\;1.8\;{\mu}m$)with methanol-tetrahydrofuran (95 : 5, v/v, containing 0.05 mol/L pyrrolidine-acetic acid buffer salt, pH = 10.0) as mobile phase at a flow rate of 0.5 mL/min and detected with a photodiode array detector from 350-600 nm. The seven chelates were separated completely within 2.0 min. The detection limits of lead, cadmium, mercury, nickel, cobalt, silver and tin are 4 ng/L, 3 ng/L, 6 ng/L, 5 ng/L, 5 ng/L, 6 ng/L, 4 ng/L respectively in the original samples. This method was applied to the determination of the seven transition metal in water and food samples with good results.

Novel palladium(II) complexes of the type Pd(IBA-NH)(IBA-NH') and Pd(IBA-NR)2, where IBA-NH and IBA-NR (R: methyl, ethyl, n-propyl, n-butyl, benzyl) represent isonitrosobenzoylacetone imine and its N-alkyl derivatives respectively, have been prepared. The ir, nmr, and electronic spectra of the palladium(Ⅱ) complexes have been studied. It has been determined that the isonitroso group of IBA-NH coordinates to palladium through the oxygen to form 6-membered chelate ring and that of IBA-NH' coordinates to palladium through the nitrogen to form 5-membered ring in square-planar Pd(IBA-NH)(IBA-NH') and it also has been determined that the isonitroso groups of two IBA-NR coordinates to palladium through the nitrogen to form 5-membered rings in square-planar Pd$(IBA-NR)_2$. The coordination manner of the ligands is similar to that of isonitrosoacetylacetone imines obtained by Bose, et $al.^5$.

Purpose: The purpose of this study was to investigate issues and needs related to child health management as recognized by teachers in day care centers. Methods: Data were collected from 130 teachers from 20 day care centers. Each teacher was interviewed in depth and the data were examined through content analysis. Results: For issues on child health management, the analysis scheme consisted of 10 categories and 36 subcategories. For needs on child health management, the analysis scheme consisted of 10 categories and 37 subcategories. Teachers indicated that tools for physical examination and playgrounds were insufficient and they had difficulty in controlling attendance of infectious children. They also indicated the lack of a linkage between day care centers and hospitals, lack of knowledge of health management, high teacher versus child ratio, and lack of help and budget needed for health care. Conclusion: The results of this study suggest the need to develop a linkage between day care centers and medical institutions. Also there is a need to provide support from health care personnel, health education for teacher, health management manuals for teachers, and financial aid to satisfy the needs for health management in day care center for children.

The objective of this study was to investigate the effect of an education method applying the flipped learning technique for college students. Both self-directed learning readiness and educational performance before and after applying the flipped learning were examined. After applying the flipped learning technique, teacher-student interaction, learning satisfaction, and learning motivation were identified. The correlation of each variable was examined after applying the flipped learning technique to investigate its influence on learning motivation. A total of 68 second-year nursing students enrolled in E University were analyzed. A difference between before and after applying the flipped learning was analyzed by the paired t-test; a correlation between the variables was analyzed via Pearson's correlation coefficient; and an influence on the dependent variable learning motivation was analyzed using the stepwise multiple regression analysis. The results showed that self-directed learning readiness increased before and after applying the flipped learning technique with statistical significance, and the difference of educational performance was not significant. After an education session applying the flipped learning technique, a learning motivation demonstrated a significantly positive correlation with self-directed learning readiness (r=0.33, p=.006), college student educational performance (r=0.51, p<.001), teacher-student interaction (r=0.72, p<.001), and learning satisfaction (r=0.79, p<.001). A significantly positive correlation was also observed between the other variables. Factors influencing learning motivation were learning satisfaction and teacher-student interaction. The explanatory power for learning motivation in the regression model considering these two variables was 71.3% (F=80.66, p<.001). Therefore, to enhance learning motivation in applying the flipped learning technique, it is necessary to increase learning satisfaction and to establish a strategy that further vitalizes the teacher-student interaction.
