Objectives The purpose of this study is to find out the effect of KyungOcGogamibang(KOGE) on the growth of rats. Methods First of all, we divided male Sprague-Dawley rats into 4 groups(KOGE1, KOGE2, KOGE3 and control group). Then KOGE1, KOGE2 and KOGE3 groups were administered with KOGE water extracts once a day at a dosage of 250, 500, 1,000mg/kg respectively for 3 weeks. The control group was administered with normal saline in the same manner. We measured the rat's body weight, amount of body weight increased, length of femur, serum GH, serum IGF-Ⅰ, serum TSH and serum testosterone after each week of administration. Results 1. There were significant changes of the rat's body weight, the length of the femur, the level of GH, IGF-Ⅰand TSH in KOGE1 groups. 2. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE2 groups. 3. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE3 groups. Conclusions According to the results above, rat in KOGE group have been increased their body weight, length of femur, serum GH, serum IGF-1 compared to the control group. This study shows that groups of KOGE have an effect on promoting the growth, thus it is expected to treat growth problems for children.

This study explores the development of parking tactics for improving parking problems in apartment estates of the Seoul Metropolitan City(SMC). This study is aimed to review a basic theory of apartment parking, to analyze the parking facilities and behaviour, and to present the parking tactics for improving the parking problems in Seoul's apartment estates. This study was conducted by the analysis of secondary data and a content analysis of the research reports and papers. Parking is an essential and integral part of urban transportation as well as a major urban land use. The parking problem in SMC resulted from rapid increase in car ownership, inadequate parking facilities, and lacking road networks. Today, the parking problem in Seoul has become an integral part of the transport problems as well as a social issue for Seoul Metropolitan Government to solve urgently. The population of Seoul increased at an annual average growth rate of 1.7% during the 1982∼1993 period. The total number of private car ownership increased rapidly at an annual average rate of 21.3% during the same period. The parking demand will increase continuously in the future. Parking requirements in apartment estates are related to each dwelling units in Seoul ; one space per 75㎡ for apartments below 85 m floor area, one space per 85㎡ for apartments above 85㎡ floor area. In Seoul, the parking demand of general units shows 0.81 spaces per unit and the 88.9% of parking supply. About 51.1% of the inhabitants in apartment estates parked their private cars at the parking area. Around 42.4% of the residents there indicated that the parking conditions were inconvenient. The parking situation in Seoul's apartment estates is deteriorating, with the consequence that parking problems, especially of transportation, attracted considerable popular attention in the 1990s. Especially, the parking problem in apartment estates stems from insufficient parking facilities, and has negative consequences : traffic congestion, traffic accidents, pedestrian safety, and quality of life environment. The significant parking tactics are associated with reserved parking lots for each dwelling unit, designated parking lots for short-term visitors, establishment of parking facility funds, joint use of parking facilities, residential parking permit programs, and regulations on curb parking in institutional and managerial perspectives. Parking tactics in the parking supply side are involved in improvement on parking requirements for apartments, separating parking lots from apartments for sale, improved circulations and parking lot sites, construction of apartment's parking lots, increasing parking layout efficiency, and construction of public parking facilities.
