This experiment was conducted to investigate the effect of long-term fertilization on the yield and quality of soybean. The yield of soybean was highest in the NPK+lime $1.5Mg\;ha^{-1}$ treatment. Carbohydrate content of soybean was high in the non-fertilizer treatment and crude protein content was high in the NPK+lime $1.5Mg\;ha^{-1}$ and NPK+silicate $1.5Mg\;ha^{-1}$ treatment, and crude lipid and ash content was high in the NPK+silicate $1.5Mg\;ha^{-1}$ treatment. The content of inorganic compounds were not different among treatments. Correlation between $P_2O_5$/T-N and carbohydrate, crude lipid was $-0.99^{**}$, $-0.94^{**}$ respectively. Correlation between Mn and carbohydrate was $0.95^*$, but others were not significantly different. Yield of soybean increased with lime application and protein content increased with silicate application.

This experiment was carried out to determine the proper time for flower bud removing to improve growth, yield and paeoniflorin content of root in peony(Paeonia lactiflora Pallas). The flower buds removement caused short stem length by $7{\sim}9cm$ compared with control, but number of stem and stem diameter were similar to that of control. The number of root, fresh root weight and paeoniflorin content in peony increased when their flower buds were removed at earlier stages. The root dry weight was highest of 1.647kg/10a, and increased by 27% compared with control when their flower buds were removed at early stage (bud diameter was less than 10mm). The root dry weight increased by 13% and 10%, respectively. when their flower buds were removed prior to flowering and at flowering stage. Paeoniflorin content in leaf was higher than that in stem, and was higher at early stage. Leaf and stem showed higher paeonif1orin content when their flower buds were removed.

1. The pathogenic fungi which infect to shoot of peony was 7 species. The infected parts were as followed, leaf spot disease was in leaf, leaf blotch was stem, powdery mildew was whole aeri­al part of both leaf and stem. 2. The major diseases were leaf spot and powdery mildew, and begin to occur from late April to mid­dle May, and then rapidly heavy infected. The 'Euiseongpeony' variety was more susceptible to those diseases than the 'Yeongcheonpeony' variety. 3. The blight of top part by seasonal in 1995 was begun at late May and increased rapidly 50.6% in Early August.

This study uses the "Sejong chronicles" ritual manual to investigate the movements and roles of provincial governors during the enshrinement rituals of the royal portrait, the official uniforms of the provincial governors in their roles, and the characteristics of the official uniforms system for local governors in the early Joseon Dynasty. The results of this study are as follows. Provincial governors who participated in the enshrinement rituals of the royal portrait were governors 'en route' and governors 'in destination'. The movements of the governor 'en route' followed the provincial borders, official residences, and neighboring provincial borders. The movements of the governor 'in destination' followed the provincial borders, the official residence, and jinjeon. The roles of the governors included the welcoming ceremony, the bow-down ceremony, the front guard, and the farewell ceremony. The governors 'en route' wore Jobok in the welcome ceremony, and a Sibok in the bow-down ceremony before the farewell. The governor 'in destination' wore Jobok in the welcome ceremony, and Jobok (or Sibok if Jobok was not available) in the bow-down ceremony before the farewell. The characteristics of the official uniforms system for local governors in the Joseon Dynasty were as follows. First, the governors wore different uniforms depending on the importance of the rituals in the early Joseon Dynasty. Second, the names of official uniforms Sang-bok and Si-bok were used interchangeably in the early Joseon Dynasty. Third, local governors were allowed to wear Sangbok (or Sibok) instead of Jobok.

These studies was conducted to investigate the influence of ALLELOPATHIC effects of upland weeds on crops and soil microorganisms. The aqueous extract of weed residues were used to identify physiological controll of plant and microorganisms. The results obtained are as follows : 1. The aqueous extract of weeds controlled germination and growth of plant, especially the 5%-extract of Potulaca oleracea suppressed the growth of soybean about 8~12%. 2. The 5%-extract of Potulaca oleracea inhibited effect of phytosynthesis of soybean about 60%. 3. The move the concetration of phenolic compounds in soil, the less a number of actinomycetes and bacteria. 4. The number of soil microorganism(fusarium oxysporum spp.) were decresed as to the concentration of vanillic acid was increased.

Monitoring or follow-up surveying pesticide residues in agricultural commodities is the key to meet the international regulations and to enhance international competitiveness of Korean agricultural commodities. Six neonicotinoid insecticides, acctamiprid, clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam were monitored in 95 paprika samples collected from Gyeongnam area. Thc pesticide residues were extracted by EN 15662 buffer based on the QuEChERS method, clean-upped with dispersive solid-phase extraction method to remove interfering pigments, and analyzed using UPLC-MS/MS. The neonicotinoid pesticides were detected in 90.5% of the paprika samples. Two or more pesticides were detected in 82.3% of samples. Although detection frequencies were high, all samples complied with the maximum residue limits (MRLs) set by both the Korea Food and Drug Administration (KFDA) and Japanese Ministry of Health, Labour and Welfare.

The purpose of this study is to suggest objective basic data for park management proposal through the quantitative analysis of users' behaviors and satisfaction for the actual conditions of management in Moaksan provincial park. For this, users' behaviors and socio-ecnomic characteristics have been analyzed. Specifically, it attempts to investigate users' anticipation and degree of satisfaction applied Expectancy Theory by Likert scale. And users' satisfaction for the actual conditions of management had been analyzed by using the multiple regression. Results of this study can be summarized as follows ; From the aspect of utilization reality, the male usage was silighty higher than female usage, and the usage rate reality, the male usage was slighty higher than female usage, and the usage rate among the young and students such as university students also appeared slightly higher than the norm. Due to the fact, subject park had been provincial park, bus usage was predominant, and users' visit park 1 or 2 times a year. Generally, the value of users' post occupancy evaluation were higher than those of anticipated, and Use in night and facilities were lower. A sense of the season, dense of forest, beauty of skyline and a perspective view appeared as main explicatory variables having positive effects on the satisfaction level for the landscape. Amount of plant and shade were positive variables on the satisfaction and users' had dissatisfaction with trial damage. According to the multiple regression analysis, the major variables to the satisfaction for the actual condition of vegetation management were diversity, recovery of artificial injury.
