  • Background: Video-assisted thoracic sympathicotomy plays an important role as an effective method for the treatment of axillary hyperhidrosis. People with axillary hyperhidrosis were not satisfied by the occurrence of the high rate of disabling compensatory hyperhidrosis and axillary resweating. Therefore, by comparing and assessing the clincal results according to the level and extent of sympathicotomy in axillary hyperhidrosis, we aim to determine which method will result in maximal benefits. Material and Method: Among 70 patients suffering from axillary hyperhidrosis having undergone thoracoscopic sympathicotomy from January 2001 through December 2003, 57 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into two groups, Group 1 (n=25): patients having undergone R3, 4, 5 sympathicotomy which consist of blocking the interganglionic neural fiber on the third, fourth, and fifth rib, Group 11 (n=32): patients having undergone R3,4 sympathicotomy which consist of blocking the interganglionic neural fiber on the third and fourth rib. The study parameters were satisfaction rate and degree of compensatory sweating. Result: There was no difference on age and sex, family history, combined hyperhidrosis, and mean follow up month between the two groups. Patients expressing satisfaction were $88.0\%$ in group and $56.3\%$ in groups 11 with statistically significant difference (p=0.02). Moderate to severe compensatory sweating were $52.0\%$ (embrassing 6 patients, disabling 7 patients) in group 1 and $62.5\%$ (embrassing 5 patients, disabling 15 patients) in groups 11 with no significance in the statistical analysis. Conclusion: R3, 4, 5 sympathicotomy was an effective means of treating axillary hyperhidrosis because of higher long term satisfaction rate.

  • Single-node stem pieces ca. 1 cm in length containing a axillary bud were obtained from in vitro plants of potato (Solanum tuberosum L.). The influences by a position of the node and the existence of a leaf at the node were observed in the single-node culture on the 8% sucrose MS medium. The effect of CCC was also investigated for the microtuberization. The apical part node was excellent in the tuberization not to mention shoot length, fresh weight, diameter, the number of node on the in vitro culture of a single-node than the lower part. The differences in the diameter of a tuber formed in the part of the axillary bud on all treatments including the cultivation of the apical part node were not recognized. However, the fresh weight of the tuber showed high value in the tuber formed at the axillary bud of shoot apex part. At 20 days after cultivation, tuberization was promoted in the new stolen that developed from the bud of node with a leaf under SD condition of 8 hours at $20^{\circ}C$. The tuberization from axillary bud of the single-node without leaf was inhibited at high temperature of $28^{\circ}C$ regardless of daylength. Whereas, tuberization at $20^{\circ}C$ and $28^{\circ}C$ was similar without the difference under SD condition but the tuber formation ratio were low. CCC 500 mg/L promoted tuberization and the effect was also showed even under LD condition at $28^{\circ}C$. The inhibiton of tuberization under LD and high temperature condition could be solved by treatment with CCC.

  • Several agronomic characters, feed value, and mineral uptake of two corn hybrids infected by different degrees of rice black-streaked dwarf virus (RBSDV) were studied at the south-eastern part of RBSDV prevalent areas in Korea. Although both hybrids were infected with RBSDV by 100%. culm length of Suweon 19 was more severely reduced than that of Jinjuok and there were positive correlations between culm length and top dry weight of individual plants. The reduced culm length was largely due to the shortened length of upper five internodes in both hybrids and also due to the reduced number of internodes in Jinjuok. As culm length reduced, percent ear-bearing plants, average ear weight, and number of kernels per ear reduced significantly in both hybrids. The kernel weight of Suweon 19 decreased with reduced culm length, but that of Jinjuok was similar among the different culm lengths. However, as culm length decreased, crude protein and fiber in whole plants and N, P, K, Mg in culm + leaf sheath increased, but nitrogen free extract in whole plant decreased. And crude fat in whole plant and N, P, K, Mg concentrations in leaf blades and ear were similar among the culm lengths.

  • The study was conducted to determine the efficiency in producing spontaneous polyploids in some mandarin hybrids with different seed embryony. Seed formation by open pollination, frequency of spontaneous polyploids, and plant growth characteristics were evaluated in four mandarin hybrids with polyembryony such as 'Amakusa', 'Haruka', 'Hayaka', and 'Seminole' and two with monoembryony such as 'Benibae' and 'Harehime'. The mean number of the developed seeds per fruit was 10.0 and frequency of small seeds was 25.1%. Polyploids were selected from plants germinated in vitro by a flow cytometry and confirmed by chromosome analysis. One triploid was produced from 'Harehime', one tetraploid, 'Amakusa', and one tetrapoid, 'Benibae'. There were little differences in leaf shape, thickness, petiole length, and internode length between diploids and polyploids such as tri- or tetraploid. However, polyploids had larger stomata and lower density of stomata in abaxial epidermis than diploids. SPAS indicating chlorophyll content and photosynthetic rate were significantly affected by ploidy level. The results indicated that spontaneous polyploids might be produced by open pollination in some mandarin hybrids and monoembryony had higher frequency in polyploid occurrence than polyembryony.

  • The experiment was carried out to examine the effects of planting date on the growth and marketable yield of bitter gourd grown in rain-shield plastic houses. Bitter gourd cv 'Dragon' seedlings were separately transplanted during the months of June, July and August, 2015. The training method of all plants was made with four lateral vines and pinching the main vine. Lateral length of plants exhibited no significant difference between each planting date. However, bitter gourd planted in June had significantly higher main stem diameter than those treatments planted on August. The application of planting date was found effective in increasing marketable yield and number of fruits. June, as a planting date, had the highest marketable yield (6,439kg/10a), whereas bitter gourd planted in August had the lowest yield (870kg/10a) which were also consistent in terms of the number of fruits. Fruit length and diameter had no significant differences as affected by treatments. Therefore, planting date of bitter gourd in June was effective in increasing yield of fruit in rain-shield plastic house conditions.

  • This study was carried out to study the effect of eggplant (EG203) grafting and strawberry removal time on succeeding tomato cropping in high temperature season. In non tillage culture, bacterial wilt incidence was 30% and 0% in nongrafting and eggplant (EG203) grafting while 25% in non-grafting and 0% in eggplant (EG203) grafting in tillage culture. Commercial yield was similar in tillage and non-tillage culture using EG-203 grafting as 2,693 kg/10a and 2,657 kg/10a respectively with no difference in soluble solid content and hardness. Strawberry removal time after tomato planting enhanced plant height and internode length in 20days and 30days later removal while no difference in other growth characters. Commercial yield was higher as 1,885 kg/10a in strawberry removal before tomato planting than 1,678 kg/10a in 30days later removal. From this research, strawberry removal time should be determined by considering strawberry price and growth and expecting profit by succeeding tomato cropping.

  • In this study, the productivity of bioethanol obtained from various domestic raw materials (barley, brown rice, corn and sweet potato) by simultaneous saccharification and fermentation (SSF) process was estimated. Also, optimal conditions of temperature, time and enzyme concentration in gelatinization and liquefaction process were investigated. As a result, corn showed high ethanol yield of 90.45% and sweet potato had a rapid fermentation time. Productivity of bioethanol increases in accordance with the starch value of raw materials except brown rice. Therefore, it is very important to understand the structure of starch. Further studieson the characteristics of raw materials are necessary to enhance the productivity of bioethanol.

  • This study was conducted to examine the effect of LED light quality and treatment time on the growth and flowering in potted plants of Impatiens (Impatiens hawkerihybrid). Plant height of Impatiens was enhanced under Blue light, regardless of treatment time. Root length and stem diameter of Impatiens were enhanced by Red light or Blue light. The number of internodes was not influenced by LED light quality. The number of branches of Impatiens was increased under Blue light, but treatment time did not result in statistically significant differences. Leaf area was increased by all LED lights in Impatiens. The number of flower buds and open flowers was decreased by LED light, but days to flowering were reduced by Red light in Impatiens. Chlorophyll and anthocyanin content were not significantly affected by LED light, but anthocyanin content tended to increase by Blue light for 4 h after sunset. Fresh and dry weights were enhanced by Blue light in Impatiens.
