This study was conducted to estimate the appropriate workforce of dietitians by type of kindergarten through the recognition survey and job analysis of the kindergarten. Nutritionists' duties were classified into 6 duties, 28 tasks and 94 task elements. The statistical data analysis was completed using Statistical Package for the Social Sciences (SPSS) (ver. 25.0). The time spent on 6 duties, including 'Nutrition management' (public attached 666.24 hours/year, public independent 843.04 hours/year), 'Foodservice management Practices' (public attached 1,472.52 hours/year, public independent 1,298.11 hours/year), 'Hygiene management of kindergarten foodservice' (public attached 611.78 hours/year, public independent 607.18 hours/year), 'Nutrition-diet education and counseling' (public attached 340.53 hours/year, public independent 253.42 hours/year), 'Managing snack during semesters and lunch/snacks during breaks' (public independent 309.04 hours/year) and 'Professionalism enhancement' (public attached 88.86 hours/year; public independent 65.17 hours/year). Total working hours for dietitians were 3,179.94 hours/year (public attached) and 3,375.97 hours/year (public independent). The time/day ×5 days/week ×52 weeks/year calculation method using derived total working hours/year was applied to derive appropriate full-time equivalents (FTEs). The analysis showed that the public attached kindergarten's FTEs were 1.53. The public independent's FTEs were 1.62, and the total FTEs were 1.55. This is the first study to analyze the workload of kindergarten dietitians and appropriate manpower by kindergarten establishment type. It is expected to be a valuable policy basis for efficient operation measures related to the kindergarten dietitians.

Optimum soil management of chestnut orchards is important to ensure high quality and yields of chestnut. This study was conducted to evaluate soil and green leaf characteristics by establishment periods of chestnut (Castanea crenata Sieb. et. Zucc.) orchards in Sancheong-gun, Gyeongsangnam-do. Total 30 plots with the criteria of similar cultivation practices were chosen and classified into two establishment periods by over 20-year-old orchards (17 plots) and below 19-year-old orchards (13 plots). Soil bulk density was significantly higher (p<0.05) in over 20-year-old ($1.16g\;cm^{-3}$) than in below 19-year-old ($1.03g\;cm^{-3}$) plots. Soils in over 20-year-old plots were severely acidified with pH 4.56 compared to pH 4.73 in below 19-year-old plots. However, soil organic matter, total nitrogen, available phosphorus, and potassium were not significantly different (p>0.05) between both establishment periods. Leaf area, leaf mass, and nutrient (N, P, K, Ca, Mg) concentration of green leaves were also not significantly different (p>0.05) between both establishment periods. The results indicate that soil bulk density in chestnut orchards is dependent on the establishment periods, while soil chemical property and leaf nutrient concentration may be little influenced by the establishment periods.

The purpose of this study is to fiure out the floral changes during three years after construction of the Youido Ecology Park. Yearly change of plant species composition, distributed at the research field, had been investigated for three years since 1996. To compare and investigate the changes of the establishment of the Ecology Park, we have analyzed the distribution characteristics of plant species, exotic naturalized species, and so on. The results obtained through this investigation are as follows; 1) Total numbers of plant species were 106, 170, 175, and 148, in the year of 1996, 1998 1999, and 2000, respectively. While the most of cultivated species before th establishment were decreased, the naturalized species such Phargmites communis Trin, and Artemisia selengensis Turcz. etc, were increased. 2) Forty three species of exotic naturalized species were investigated and were increased at the early stage of the establishment, but showed decreasing trend recently. 3) Sixty five species of introduced and planted species were investigated. Most of them were occurred at the first year after the establishment, but since 1999, there has been a significant decrease. 4) Sixty seven species among total 235 were verified as the wetland-adapted plants. The ratio to the total numbers were low, but the occupied area of a few species was expanded. Therefore, it indicates that monitoring on the physical environments of the Youido Ecology Park was urgently required.

The purpose of this study was to investigate the present state of e-business according to the establishment year and the sales approach of Dongdaemun clothing market and to present problems according to e-business activation of it and its developmental direction. The subjects for this study were selected out of Dongdaemun clothing markets being considered as more fashion-oriented markets and were divided into two categories both according to the establishment year and according to the sales approach. As a result, Dongdaemun clothing markets are mainly divided into traditional wholesale market, eastern wholesale & retail market, and western retail market and having dealings with each other according to the market's characteristics. The utility percentage of on-line e-business according to the establishment year and the sales approach showed that traditional wholesale market was 42%, eastern wholesale & retail market 0.75%, and western retail market 11%. This result indicated that the utility percentage of traditional wholesale market showed much higher than eastern wholesale & retail market and western retail market. This would be because the structural characteristics of clothing market delayed the utility of e-business. For the problems on the utility of on-line e-business through counselling, traditional wholesale market showed much higher than wholesale & retail market and retail market because it had little problems on design imitation in retail market due to export by order and mass production. The problems of low utility of on-line e-business in Dongdaemun clothing market would result from well-timed on-line update according to rapid goods cycle, constant satisfaction for additional order, standardization of size and quality, and inexpensive internet purchase despite of express expense.

This study was carried out to investigate the seedling establishment and yield of direct-sown Platycodon grandiflorus seeds cultured by three ridge width, 0.4, 0.8, and 1.2 m and four mulching materials, rice straw, rice bran, black plastic film, and no mulching in upland. Seedling establishment rate (70%) was the highest in rice straw mulched plot of 500 seeds/$m^2$ sowed and root yield after one year was also the highest in rice straw mulched treatment and followed by rice bran, no mulching, and black plastic film treatment. In this result, ridge width 120cm and rice straw mulching combined treatment was best for getting the highest seedling establishment ratio and seedling numbers per area. However, ridge width and mulching materials should be considered soil moisture content and weed population for saving labor cost.

Shading and soil environment are the main factors of growth and yield in ginseng (Panax ginseng C. A. Meyer). Ginseng yield is directly related to survival rate because of increased missing plant for their growing period. Under field conditions, diseases and pests significantly affect plant survival rate. We evaluated the seedling establishment, growth and ginsenoside of the ginseng plants, under controlled management conditions in a plastic greenhouse, when their treated with different types of organic matter. Ginseng seeds were sown at a rate of three seeds per hole, and the seeding space measured $10cm{\times}15cm$. Compared to the control, treatment of cattle manure vermicompost (CMV) was shown to increase seedling establishment and decrease ginsenoside content. Root weights of plants treated with CMV were higher than those of plants treated with other types of organic matter. In addition, seedling establishment of 2-year-old ginseng plants was decreased when it was compared to that of 1-year-old ginseng plants. Our results indicated that organic matter type and rate were associated with seedling establishment, growth characteristic and ginsenoside content in greenhouse of ginseng direct-sowing culture.

The food life of Korean people during the establishment of Republic of Korea and the Korean war was reviewed. After liberation in 1945, the division of South and North Korea, the establishment of the governments, and the ensuing Korean War made Korean society extremely chaotic and transformed. Consequently, data on Korean dietary life during this period (1945-1960) are scarce and unreliable. The author tried to reveal the food situation and health and nutritional status of Koreans during this period by examining the data released by the US National Archives and other review books. Regarding the nascent period of the food industry after the Korean War, data from the recent 50-year history of the Korea Food Industry Association has been compiled.

The establishment by seeds and the maintenance by ramets of the autumn olive (Elaeagnus umbellata) population were investigated in the Namhansansung Provincial Park, Jungbu-myun, Kwangju-gun, Kyunggi-do. Seed production and germination rate were 3, 300 $seeds{\cdot}m^{-2}{\cdot}yr^{-1}$ and 52%, respectively. The ramet formation in the population was classified into 4 types: stump type, creeping root type, lateral root type and secondary creeping root type. The subterranean creeping roots were 0.1~1.0 m in length, 4.5~14.0 mm in diameter and 0.06~0.2 m in soil depth. The number of ramets formed from a node was 1~21. The subterranean roots spread $5~509cm^2{\cdot}plant^{-1}{\cdot}yr^{-1}$, which began to be produced from 7~9 year-old individuals. The number of stems was 1~67 per stump, which was reduced by self-thinning from 2 to 14 year-old trees. The frequency distribution of stem diameter$(D_{30})$ showed a reverse J-shaped curve, suggesting that this population be maintained perpetually by their own ramets.
