A new sesame variety Kangbaek was developed from Yeongnam Agricultural Research Institute in 2004. Cros wasmade by lodging resistant SP9003-3 line to the F1with high yielding capacity, folowed by pedigree selection, yield test and RYT by the sesame breeding team at the National Insti-tute of Crop Science up to 2003. The variety showed higher disease resistance, especially phytophothra disease, and lodging resis-respectively. It's 1000 grains weight was about 2.54 g indicating 0.03 g heavier than that of Yangbaekkae, and it's oil content wasabout 52%. Kangbaek also contained total 7.65mg/g of such lignans as sesamin and sesamolin. The average yield of Kang-baek was 82 kg per 10a at the national-wide regional performance.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

This experiment was conducted to develop optimum sesame cultivation practices as succeeding cropping system of watermelon in the greenhouse condition. We also compared major components in sesame seed cultivated in the greenhouse and open field condition. The adaptable varieties under the greenhouse condition were white sesame 'Pyoungan' and black sesame 'Jinki' which showed higher yield and disease resistance. We also conducted several experiments to determine optimum sowing date, planting density and pinching time. Grain yields were statistically different according to the several sowing dates. In general, sesame sowing on June 30th showed higher grain yields than July 10th, July 20th and July 30th in the greenhouse. We also found out sesame cultivation practice with the row spacing of 40 cm and interplant spacing of 30 cm (a few branch type) or 40 cm (many branch type) showed higher yield than other treatments. Optimum pinching time was 25 days after first flowering in main stem when thousand seed weight and grain yield were highest. In the comparison of major components of sesame at the different cultivation conditions, sesame seeds cultivated in the greenhouse contained 4% much more oil content than open field condition. The lignan compounds, sesamin and sesamolin were also higher by 6% in the greenhouse than open field condition. It was concluded that sesame cultivation practices as succeeding cropping system of watermelon in the greenhouse condition guaranteed higher grain yield with less labor input which is now emerging alternative farming practice system in present aging rural society and will also give sesame cultivation farmers to increase net income in Korea.

Application of genotype by environment ($G\;{\times}\;E$) interaction would be used for identifying optimum test condition of the varietal adaptation in the establishment of breeding purpose. Yield and yield components were used to perform additive main effect and multiplicative interaction (AMMI) analysis. Significant difference for $G\;{\times}\;E$ interaction were observed for all variable examined. For yield, 0.18 of total sum of squares corresponded to $G\;{\times}\;E$ interaction. Correlation analysis was carried out between genotypic scores of the first interaction principal component axis (IPCA 1) for agronomic characters. Significant correlations were observed between IPCA 1 for yield and capsule bearing stem length (CBSL), number of capsule per plant (NOC). The biplot of grain yield means for IPCA1 which accounted for 34% of the variation in total treatment sums of squares showed different reaction according to $G\;{\times}\;E$ interaction, genotypes and environments. Taegu showed relatively lower positive IPCA1 scores, and it also showed smaller coefficient variation of yield mean where it is recommendable as a optimal site for the sesame cultivar adaptation and evaluation trial. In case of variables, Yangbaek and M1 showed relatively lower IPCA1 scores, but the score direction showed opposite each other on the graph. Ansan, Miryang1, Miryang4, and Miryang6 seemed to be similar group in view of yield response against IPCA1 scores. These results will be helpful to select experimental site for sesame in Korea to minimize $G\;{\times}\;E$ interaction for the selection of promising genotype with higher stability.

This study was conducted to evaluate the growth characters and yield components of 18 collected sesame cultivars to get basic information on the variation for the sesame breeding using principal component analysis. All characters except days to flowering, days to maturity and 1,000 seed weight showed significantly different. Seed weight per 10 are showed higher coefficient of variance. Capsule bearing stem length and liter weight showed positive correlation with seed yield per 10 are. The principal components analysis grouped the estimated sesame cultivars into four main components which accounted for 83.7% of the total variation at the eigenvalue and its contribution to total variation obtained from principal component analysis. The first principal component (Z1 ) was applicable to increase plant height, capsule bearing stem length and 1,000-seed weight. The second principal component (Z2 ) negatively correlated with days to flowering and maturity by which it was applicable to shorten flowering and maturity date of sesame. At the scatter diagram, Yangbaek, Ansan, M1, M2, M4, M7 and M9 were classified as same group, but M10, Yanghuk, Kanghuk, M5, M6, M12 and M13 were classified as different group. This results would be helpful for sesame breeder to understand genetic relationship of some agronomic characters and select promising cross lines for the development of new sesame variety.

This experiment was conducted to develope optimum cultural system of sesame under greenhouse condition with the comparison of open field cultural condition. The relatively higher adaptable varieties under greenhouse condition were white sesame "Pyoungan" and black sesame "Jinki" which showed higher yield potential and disease resistance. To set up standardized cultural system under greenhouse condition, we conducted several experiments of optimum sowing date, planting density and pinching time etc. When it came to sow sesame seed soon after early cultivated crops were harvested, the yield potential was higher than those of other sowing dates. Therefore, "June 30th" was optimum sesame sowing date in the greenhouse cultivation system. We also found out the space of 40㎝ between rows and 30cm(a few branch type) or 40cm(many branch type) between plants was better than those of other treatments. Optimum pinching time was 25 days after first flowering date when 1000 seeds weight and yield potential showed higher than other treatments.

Eukaryotic translation initiation factor 5A (eIF5A) is the only hypusine-containing protein, which is formed by deoxyhypusine synthase (DHS) and deoxyhypusine hydroxylase (DOHH). DOHH is a novel metalloenzyme with HEAT [named for human huntingtin (H), elongation factor 3 (E), a subunit of protein phosphatase 2A (A), and the target of rapamycin (T)]-repeat motifs. Inspite of much progress in determining the roles of iron-containing DOHH holoenzyme as an eIF5A hydroxylase, little is known about iron-free apoenzyme of DOHH under certain stress conditions. For this purpose, we compared cell growth in two yeast strains subjected to oxidative damage. Thus, the existence of more viable cells in the Saccharomyces cerevisiae BY4743 (parental yeast) strain than in the DOHH- strain after $H_2O_2$ treatment indicates the importance of DOHH in protecting yeast cells against oxidative stress. To identify endogenous target proteins influenced by DOHH under oxidative damage, proteomic analysis was applied to the two yeast strains. Of these proteins, the oxidized form of peroxiredoxin I (PrxI) was concomitantly up-regulated in both strains under $H_2O_2$ treatment. Two-dimensional electrophoresis (DE) followed by immunoblot analysis shows that the recovery of the oxidized PrxI to the reduced enzyme under $H_2O_2$ treatment was found to be much slower in the DOHH- strain than in the parental strain. Based on the results, we discovered a possible interaction between DOHH and PrxI by immunoprecipitation/immunoblotting in yeast under oxidative stress. Taken together, these results suggest that DOHH might be a candidate protein for protection of yeast cells against oxidative stress in conjunction with PrxI.
