The purpose of this study is to figure out the differences in children's 'sense of place' followed by their development stages and to suggest a positive space design of school suited by their development. Haeng-Hyeon Elementary school was selected as the target area. The research methods of this study were based on drawing the cognitive map and a questionnaire survey. Through the cognitive map, children's development stages were determined. Also, through an awareness assessment, the places where the children had deep recognition were extracted. The questionnaires were based on knowing the places where children create their 'sense of place' and its reasons. The sense of place development factors are comprehended as physical factor, behavioral factor and psychological factor based on Relph(1976). The results were organized into a guide which has to be considered when designing an elementary school, sorted by adequate space responding to children's development stages.

The purpose of this study was to find out the effects of education for prevention of child sexual abuse (rape, sexual assault, sexual harassment etc.) of children in elementary school students. Incidences of sexual abuse in Korea is ranked 3rd in the world. Sexual abuse of children, particularly, is one of the most serious crimes that affect both the victimized children and their family. The issue related to sexual abuse of children has been ignored, and there is a lack of systematic education to prevent sexual abuse of children either for children or their parents. Furthermore, lack of knowledge and poor attitude of teachers limit their capability to provide education for sexual abuse prevention to the children. The education for teachers may change their knowledge of the sexual abuse and their attitude toward it and improve their capability in helping children. 223 Korean elementary school students participated in this study. Research design was One group pretest-posttest design. The education given to the subjects included 4 hours through the multimedia CD-ROM on the prevention of child sexual abuse. The education program was developed based on a survey. School- aged- children, parents, and teachers were interviewed to reveal their educational needs based on their experiences related to sexual abuse. This program includes such as safety education, crisis management, resource person(s), and phone numbers of available hospital. Data was collected before, during and after the education was given to the subjects, to assess their knowledge and attitude toward child sexual abuse. Two instruments were used in this study. Using Cronbach's ALPHA validity and reliability of 2 instruments were tested. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics, t-test and ANOVA. The results of this analysis were as follows : 1. After education, the score of school nurses knowledge was higher than before(t= -4.677, p=0.000). 2. After education, the score of school nurses attitude was not higher than before (t=0.131, p=0.896). The findings from this study will provide an intervention strategy for prevention of sexual abuse in children.

Children's wear needs extra safety features to avoid unexpected dangers. On the way to school, children are exposed to traffic very often. Especially in the early morning or late evening, or on dark cloudy days, they might be unrecognized by drivers without safety reflectors on their clothing as a means of raising visibility. Therefore, safety reflectors on clothing can protect children from traffic accidents. The research was carried out as follows. 1. Reflector manufacturers were interviewed regarding how Reflective and Reflexite reflect light back to the light source, what kind of safety reflector products are available, and how these materials are being used in the clothing industry. 2. Mothers of primary school children were interviewed to find out what they think about the effect of safety reflectors, the need for clothing using safety reflectors and the design preferences. 3. In order to apply safety reflectors efficiently, the position on the clothing of the greatest visibility from the light source must be determined. 4. Shirts, pants and jumpers for 8-year-old girls and boys were designed as a case study of applying safety reflectors to clothing. The designs were verified through wearing test.

This research has dual purposes. First, it was designed to determine the level of children's spatial environment in the residences, thereby, to make a vision for children's furniture as an industrial design product. Second, it was intened to find out the children's perceptual pattern toward the furniture, thereby to give some implications for future design development. For the second purpose, descriptors were screened with construct validity and their factor structure was identified. The subjects were 1,197 children from 1st grade of elemantary school through 3rd grade of middle school, and their 1,197 parents for the first purpose, and 560 children from 6th grades of elemantary school and 3rd grade of middle school for the second purpose. The first parts of findings were 1) present interests of parents of household above middle income level in Seoul in making their children's spatial environment desirable is quite high. 2) Space segregation stage in terms of physical and conceptual aspects showed very fast development, that is, there will have been very good changes for children's room to be a very well furnished and independent space for them. 3) Children's opinions were quite well reflected when purchasing the present furniture, and this tendency seemed to be more likely happend in future. These findings mentioned above gave and confirmed the visions for future children's furnished environment. The second parts of findings were such that the perceptual pattern for furniture by children showed aesthetic design appearance, functionality and durability, and the characteristic of line. This result impliated especially that designers should be every careful to manipulate or use the line of the furniture products. The 22 representative descriptors selected can be used as an evaluation instrument for furniture products.

The genus Streptomyces is intensively studied due to its excellent ability to produce secondary metabolites with diverse bioactivities. In particular, adequate precursors of secondary metabolites as well as sophisticated post modification systems make some high-yield industrial strains of Streptomyces the promising chassis for the heterologous production of natural products. However, lack of efficient genetic tools for the manipulation of industrial strains, especially the episomal vector independent tools suitable for large DNA fragment deletion, makes it difficult to remold the metabolic pathways and streamline the genomes in these strains. In this respect, we developed an efficient deletion system independent of the episomal vector for large DNA fragment deletion. Based on this system, four large segments of DNA, ranging in length from 10 kb to 200 kb, were knocked out successfully from three industrial Streptomyces strains without any marker left. Notably, compared to the classical deletion system used in Streptomyces, this deletion system takes about 25% less time in our cases. This work provides a very effective tool for further genetic engineering of the industrial Streptomyces.

The purpose of this study is to investigate the effect of obese children's life style habits in order to contribute to the prevention and management obesity. The survey group included B,D, and J elementary school children. Out of 731 children, 380 were in the obese group and 351 were in a control group following the 1985 Korea Pediatric Association Height and Weight Standard Chart. Through a self questionnaire, a description of background, exercise including play behavior, diet intake, eating behavior and, environment were obtained. The results included that children's obesity is related to parents' obesity and, girls in both control and obese groups participate less in exercise than boys. Also, aspects of the amount of diet intake and speed of eating was significantly more (p<.001) and faster (p<.05) for the obese group. Furthermore, outdoor playing time for the obese group was significantly more than the control group (p<.05). Looking at the results, it is necessary for both school and home to actively involve themselves in guidance and providing an environment that modifies life style habits to prevent childhood obesity.
