  • This study was carried out to find out the effects of date and number of defoliation by different seeding date on growth and yield of perilla. Saeyuepsildlkkae was seeded from April 30 to June 30 at 20 days interval and defoliated from June 30 to Aug. 15 with different defoliation number. 1. Days to emergence, flowering, and maturing were not significantly influenced by defoliation, but those were shortened as seeding date was delayed. The interaction between defoliation and seeding date showed no significant difference. 2. Stem length, number of nodes on main stem, and weight of dry stem were not significantly affected by defoliation, but those were decreased as seeding date was delayed. 3. Yield of fresh loaves was not significantly influenced by seeding date up to May 20, but markedly decreased by the later seeding date. 4. Cluster length and number of cluster per plant were not affected by seeding date, but number of capsules per cluster was decreased from 32 to 25 and 1,000 grain weight was increased from 3.42 to 4.62g as seeding date was delayed. 5. Grain yield was not significantly affected by defoliation and seeding date up to June 10, but markedly decreased by seeding date June 30.

  • This study consider the literary capacity and the pursuit of learning through the Haseo Kim In-hoo's a literary work. A prose poem's is composed of of six item. It is study the origin and the root of a man, the teachings of humanity and filial conduct, a meaning of learning and filial piety, the procedure and system method of learning, a rule of learning and dutiful service to one's parents, an epilog. The origin and the root of a man is founded on dutiful to thoughtful about one's parents. The teachings of humanity and filial conduct is based upon dutiful devoted to one's parents. A meaning of learning and filial piety accord with true learning and loving and respecting. The procedure and system method of learning is closely following in the teachings of Confucius and Mencius and Juja. A rule of learning and dutiful service to one's parents attaches too much importance to devotion to one's studies and substantial filial piety.

  • This study evaluated the nutrition intake and changes in laboratory data of surgery patients with hypermetabolic severity on nutrition support. From January 2002 to September 2002, 66 hospitalized surgery patients who had received enteral nutrition (EN, n=19) and total parenteral nutrition (TPN, n=47) for more than 7 days were prospectively and retrospectively recruited. The laboratory data was examined pre-operatively, and on the post-operative 1, 3, 7 day and at the time of discharge. The characteristics of the patients were examined for the hypermetabolic severity, The hypermetabolic scores were determined by high fever ($>38^{\circ}C$), rapid breathing (>30 breaths/min), rapid pulse rate (>100 beats/min) , leukocytosis ($WBC>12,000/{\mu}l$), leukocytopenia ($WBC>3,000/{\mu}l$), status of infection, inflammatory bowel disease, surgery and trauma. The scores for the hypermetabolic status were divided into three groups (mild 0-10, moderate 11-40, severe>41). According to the results of the study, 38.3% (n=23), 45.4% (n=30) and 19.6% (n=13) were in the mild, moderate, and severe groups, respectively. There was a decrease in the serum albumin level and weight loss according to the hypermetabolic severity. However, the white blood cells (WBC), fasting blood sugar (FBS), c-reactive protein (CRP), total bilirubin, GOT, and GPT increased. The nutritional intake was TPN (32.5 kcal/kg, protein 1.2 g/kg, fat 0.25 g/kg), EN (28.1 kcal/kg, protein 1.0 g/kg, fat 1.01 g/kg). The serum albumin, hemoglobin and cholesterol were higher in the EN group than in the TPN group. But the FBS, total bilirubin, GOT and GPT were higher in the TPN group than the EN group. In conclusion, there was a negative correlation between the changes in the laboratory data and the hypermetabolic severity. There was an increase in the number of metabolic complications in the TPN group.

  • This study was carried out to determine the differences in the growth, grain yield, and seed quality of sesame plant according to seeding date between P,E. vinyl-house and outdoor cultures. Reproductive growth period in vinyl-house culture was shorter than in outdoor culture. Stem length and capsule setting length of sesame were much longer in vinyl-house culture than in outdoor culture. Also, number of capsules per plant and 1,000 grain weight in vinyl-house culture were higher, specially the grain yield was approximately 57% more than in outdoor culture. In vinyl house culture, sesame plants sown on June 8 had longer capsule setting length, more capsules per plant, higher 1,000 grain weight, and higher percent ripened grain at the upper part of the capsule settings than those sown in May 9. They also had higher 1,000 grain weight at the middle and lower part of the capsule settings compared to May 9 seeding. However, no difference in grain yield of in seeding dates was observed. In outdoor culture, sesame plants, which was sown on May 9, had more effective branch number and capsule number and plant compared to those sown on June 8. Though sesame plants sown on May 9 had lower percent ripened grain at the upper and middle part of the capsule settings and lower 1,000 grain weight, the seed yield was similar to those sown on June 8. No difference in chromaticity value $L^*$ of sesame seeds between two culture conditions was observed. The $a^*$ value was higher in vinyl-house culture than outdoor culture while $b^*$ value was higher in outdoor culture. Sesaminol triglucoside content of sesame seeds was higher in vinyl-house culture than in outdoor culture. On the other hand, the content of sesamin and sesamolin from sesame seeds in vinyl-house culture were lower than in outdoor culture.

  • Perilla is an excellent oil crop for linolenic acid production but still needs more research to improve grain yield and chemical properties. We tried to estimate the possibility for improving grain yield and its quality by applying nitrogen top dressing(4kg per 10a) at 5 days after flowering stage of perilla, using a cultivar Yujin. This study investigated the growth characteristics and seed quality. Nitrogen top dressing on the flowering stage has little affected on such traits as length, node number and diameter of main stem, and branch, cluster and capsules numbers per plant. But compared with standard cultivation as a control, top dressing showed more leaf chlorophyll content by 85%, higher 1000-grain-weight by 31%, and one day extension of maturing period; consequently, grain outyielded by 60% with 123kg per 10a. Seed chemical components also showed 33.3% protein and 48% oil contents that were 11.5% and 6.2% higher than those of control, respectively. Also by top dressing, saturated fatty acid (palmitic and stearic acid) decreased and linoleic acid among unsaturated fatty acids increased. It is concluded that nitrogen topdressing at late flowering stage promotes grain yield and quality of perilla.

  • This study was conducted to investigate the effects of night illumination on the growth and yield of sesame(Sesamum indicum) and perilla(Perilla frutescens). Stem length and height of the first pod in sesame increased, whereas number of branch was reduced and flowering date and maturing date delayed as light intensity of night illumination increased. Number of capsules per plant, ripening ratio and seed yield of sesame were reduced as light intensity of night illumination increased. Yield reduction was greater in Ahnsankkae than in Sodunkkae. Number of nodes increased under night illumination in perilla. Two test cultivars showed reduction in number of branch at 6~10 Lx(22 ㎽ m$^{-2}$ ) intensity of night illumination, even though there was a variation between cultivars. Perilla was sensitive to night illumination far flowering and ripening. Flowering date was delayed by 21 to 28 days at 6~10 Lx intensity of night illumination. Number of flower clusters, number of seeds per flower cluster, and 1,000-seed weight in perilla were significantly reduced and seed yield was reduced by 89 to 98% at 6-10 Lx intensity of night illumination.

  • This study was conducted to investigate the proper fertilizer application level and top-dressing method of Lycium chinense MILL in 1984 and 1985. The results obtained were summerized as follows; Stem length was 4cm longer, leaf area was 45-490$\textrm{cm}^2$ larger, dry matter weight per plant was 1.6-5g heavier and average yield of dry fruit of two years was higher as 183kg per l0a in double amount of potassium( 14kg/l0a) application than in standard level of potassium(7kg/l0a). Highly positive correlation was found between absorption amount of inorganic elements of phosporus(l%), nitrogen, potassium(5%) and dry matter weight. Proper fertilizer application level was 13.8kg(N), 14.2kg(P) and 14.3kg(K) per l0a. Dry fruit yield of top-dress-ing plot was 20% heigher than that of basal dressing plot through increase of leaf area per plant and dry matter weight per plant.

  • The study was carried out to find effects on growth and yield by drought in Paeonia lactiflora Pallas. The water stress treatment was imposed artificially on April 1 to May 30(top part growth high stage), June 1 to July 30(root growth high stage), August 1 to September 29(late growth stage) and control(below 50kPa) in rain shelter. In drought periods of April 1 to May 30, stem length and number of stem were 67.5cm and 10.4 ea/plant. It showed poor growth compared with control, and root length and diameter also decreased to 27.2cm and 24.5mm, respectively. In root yield, drought treatment of June 1 to July 30 showed lower root yield as $1,809kg\;10a^{-1}$, $1,902kg\;10a^{-1}$ for drought period of August 1 to September 29, compared with $2,039kg\;10a^{-1}$ of control, resulting in 11% and 7% reduction, respectively. Optimum irrigation times (50kPa) was 17 days after continuos rain-off in Spring(April 1 to May 30), 9 days in summer(June 1 to July 30). It could be estimated that effective irrigation point was at least 13 days in after August(Aug. 1 to Sep. 29).

  • We established that regenerated plants of Panax ginseng were directly transplanted into the soil without the acclimatization process. When regenerated plants were treated at the concentration of $0.4mg\;l^{-1}$ for 9 hr before transplantation into the soil, our results showed that the survival rate of them was the highest. The optimal size of the root was above 4 cm in length and 0.4 g by weight before transplantation into the soil. The highest survival rate increased to 59.6%. After 4 years of cultivation in the fields, our results showed that there were no significant morphological differences between regenerated plants and wild-type ginseng. Also, we obtained healthy seeds from regenerated plants. This study provides the basis for a relatively rapid multiplication of selected genotypes and will allow a much more rapid evaluation of the germplasm of the unexplored and unstudied Korean ginseng.
