This study aims at giving examples that can be applied in the real education field, and it develops theme-based integrative education program for Industrial Specialized high school students. It analyzed the models of many scholars about the development of education course, and devised developmental models and procedures of the theme-based integrative education program of engineering specialized high school from those. As a result, it used and reorganized ADDIE model which is the systematic education course development model and the theme-based integrative education development model of Frazee and Rudnitski(1995) as the basic structure, and came to devise theme-based integrative education program of engineering specialized high school while referring to creative engineering design education program development model by Lee Chang-hoon. This study that is theme-based integrative education program for engineering-specialized high school students and is the result of this study has the following characters. First, This theme-based integrative education program that is developed for engineering-specialized high school students can be applied and the initial example that approach the Theme-Based. Second, This Education Program included the Activity project that is "Making Maglev" for the third grade at the engineering-specialized high school and One of the Program's aim is to bring up their attitude that engaged to in the class having the Interest. Third, Theme-based integrative education program for engineering-specialized high school is composed the workbook for the students and the teaching guidance plan for the teachers. Workbook for the students is composed four Units;"Brief about the Maglev","Basic principles about the Maglev","Intensive principles about the Maglev", Activity project about the Maglev". And each unit is made by Learning Purpose, Introducing, Learning Contents(Deepen Learning, Reading Magazines), Assesment etc. Teaching guidance plan for the teachers include that Summary, Purpose, Time Planing & Streaming Map for the class, contents associated Maglev, prerequisite learning, constructure of the education program, flow chart, learning activity, assesment(self-appraiser and peer review).

This study was carried to develop the new functional food material by exploring natural antioxidant substances of Crotalaria sessiflora L. We compared antioxidative activity of potential antioxidant substances extracted from Crotalaria sessiflora L. The order of extract yield of Crotalaria sessiflora L. were stem > loaves > seed > root. Antioxidative activities of Crotalaria sessiflora L. were measured by total polyphenol contents EDA (electron donating activity), SOD (superoxide dismutase) -like activity, hydroxyl radical scavenging ability and hydrogen peroxide radical scavenging ability. Total polyphenol acid content was much higher in leaves Ex than other extracts. And leaves Ex showed the most excellent antioxidative activity ($86.27\%$) in terms of SOD-like activity. The EDA was ordered loaves Ex > stem Ex > seed Ex > root Ex. Hydroxy radical scavenging ability was the most effective in loaves Ex, and hydorogen Peroxide radical scavenging ability was the highest in seed Ex. Therefore we could be certain that leaves Ex was the most effective in antioxidative activity from Crotalaria sessiflora L.

Several phosphate-solubilizing microorganisms were isolated in order to enhance the availability of insoluble phosphates accumulated in soils. Among the microorganisms, Aspergillus niger was selected and identified for this study. The phosphate-solubilizing activity. the phosphorus uptake by plants and the changes in soil microbial biomass by inoculation of Aspergillus niger were investigated. The uptake amounts of phosphorus by lettuce and pimiento were increased by inoculation of Aspergillus niger in all experimental treatments. There was negative correlation between the soil microbial biomass P and the soil phosphorus content. However the soil available phosphorus ($Y=-0.0007X^2+0.7126X^2-29.46$, $R=0.8283^{**}$) and the phosphorus absorption of plants ($Y=0.0049X^2-2.2352X+326.34$, $R=0.6350^*$) were significantly correlated to soil microbial biomass C on the positive section of quadric curve.

The purpose of this study is to investigate the effect of toddler's emotionality and mother's reaction to their child's negative emotions of social-emotional behaviors of toddlers. The subjects were 141 mothers and toddlers ranging in age from 18 to 36 months. Instruments used in this study were: 1) Early Childhood Behavior Questionnaire(ECBQ)(Rothbart, 1994), 2) Coping with Toddlers' Negative Emotions Scale(CTNES)(Eisenberg et al., 1996), and 3)Brief Infant Toddler Social and Emotional Assesment(BITSEA)(Carter et al., 2006). Data were analyzed using Pearson's correlation and hierarchical multiple regression analysis. The results of this study show that toddler's emotionality and the mother's negative reaction to their child's negative emotions were related to the social-emotional behaviors of toddler. Also, mother's reaction to their child's negative emotions have mediation effects between toddler's emotionality and social-emotional behaviors. Specifically, toddler's emotionality has a partial mediating effect on social-emotional behaviors through mother's supportive reaction to their child's negative emotions. Additionally it was also determined that the toddler's emotionality has a complete mediating effect on the relationship between mother's unsupportive reaction to their child's negative emotions and the social-emotional behaviors of toddler. Theses results support the notion that mother's character as well as child's personality at birth are critical predictors which could impact social-emotional behaviors of toddler.

The study aims to develop a assessment tool to provide the in-home disabled in a local community with appropriate services in consideration of physical, emotional, social and environmental circumstances. After collection of assesment data of 200 in-home disabled through use of the tool, a desire-extracting algorithm was developed to provide a service to real needs through the use of decision tree analysis on data mining. The study was conducted for Five months from June 2006 through October 2006, and it is divided into development of an assessment tool and extraction of real needs through the use of the tool. The basic framework of the development of the tool was established through the examination of related literature, the subjective satisfaction of the assessment tool and items were developed through the use of a focus group and experts, and verification was implemented through the use of statistics to confirm the validity of the tool. As a result of the verification, the tool secured following validity and credibility as seen in
