This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in hot pepper. In addition, correlation coefficients among the yields and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May and July showed large with coefficients of variation(C.V.) of 25.0,8.9%, respectively, but the variation of the duration of sunshine in May were relative small. Yield and plant height was greatly with C.V. of 7.14,11.6%, respectively, diameter of fruit showed more or less C.V. of 2.28% and length of fruit showed less variation. Correlation coefficients between maximum temperature in period of cultivation from May and yield are positively significant at the level of 1 %. Correlation Coefficients between precipitation in period of cultivation from May to August and yield are negative significant at the level of 5 and 1 %, respectively. Correlation coefficients amount the plant height, length of fruit, diameter of fruit per plant, and seed yield were positively significant at the level of 1 %, respectively.

This study has been carried out to investigate into the natural convection heat transfer from the isothermal horizontal plate with downward projecting fins numerically. The governing equations for the system are solved by the finite difference method and sucessive under relaxation method at Ra=10^(5), Pr=0.71, C_(F)=7.75. Mean Nusselt numbers, velocities, temperatures and stream functions are obtained for various dimensionless fin lengths. The results are as follows ; 1. The dimensionless temperature distributions decrease rapidly in fins and linearly in fluid as x/s increase 2. The mean plate, fin and total Nusselt number are decreased by increasing the dimensionless fin lengths 3. The mean late Nusselt number is less than the mean fin Nusselt number at l/s>8.0 4. The local fin Nusselt number is increased rapidly near the fin tip and that of the fin tip is decreased rapidly by increasing the dimensionless fin lengths.

Kwon,Byung-Sun,Choi,Seong-kyu,Shin,Jeong-Sik,Shin,Dong-Youn,Kyu Hwan 한국자원식물학회 2002 Plant Resources Vol.5 No.2

In order to obtain the genetic information on the quantitative characters of black seeded soybeans, which would be needed to improve selection efficiency for breeding high yielding genotype, 45 varieties of black seeded soybeans collected in Chonnam, Korea were grown and variations of several important characters were observed. Heritability of each observed character, phenotypic and genotypic correlations among the characters and contribution of each yield component on grain yield through path coefficient analysis were estimated. Both number of pods per plant and 100-seed weight showed not only high heritability but also highly significant phenotypic and genotypic correlation with seed yield, and hence it was desirable to select plants with more number of pods per plant and higher 100-seed weight than raise seed yield of black seeded soybeans collected in Chonnam. In addition, number of pods per and 100-seed weight were proved to be the most influential variables on the viability of seed yield by path coefficient analysis. Since these showed the high heritability of number of pods per plant, selection of plants with higher 100-seed weight would be more efficient for breeding high yielding genotype.

Kwon,Byung-Sun,Shin,Jeong-Sik,Shin,Dong-Young,Hyun,Kyu-Hwan,Park,Hee-Jin,Sin,Jong-Sup,Seong-Kyu 한국자원식물학회 2003 Plant Resources Vol.6 No.2

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

김환기,권문선 동아대학교 환경문제연구소 1986 硏究報告 Vol.9 No.3

본 연구는 정화조 유출수의 질소성분 제거에 관한 기초적 연구로서 주로 암모니아성 질소제거를 위한 실험적 결과에 관한 내용이다. 실험에 사용한 시료는 정화조 유출수와 유사한 합성폐수를 사용하여 그 처리가능성을 구명한 후 실제 정화조 유출수를 사용하여 비교하였고, 질산화 반응이 단계적으로 일어날 것을 고려하여 4단계 생물학적 유동층을 고안 하였으며, 이 반응기를 이용하여 질소제거 가능성을 검토하였다. 그 결과 순환비 변화에 의한 유기물 제거는 초기단계에서 80% 정도 였으며 질산화 반응은 후기단계에서 90% 이상의 암모니아성 질소가 제거되었다. 체류시간에 따른 유기물은 1단계에서 대부분 진행되어 85%이상 제거되었으며 질산화 반응은 3, 4단계에서 90%이상의 암모니아성 질소가 제거되었으며, 이때 적정순환비 및 체류시간은 각각 30과 7시간이었다. 합성폐수와 실제 정화조 유출수의 NH₄^(+)-N 제거와 NO₃^(-)-N 생성 효율을 얻기 위한 실험에서 NH₄^(+)-N 1㎎/ℓ 제거에 합성폐수는 NO₃^(-)-N 0.95㎎/ℓ가 생성되었고 실제 정화조 유출수는 0.82㎎/ℓ NO₃^(-)-N 이 생성되었다. 또한 유동층 반응기에서 질산화 반응의 동력학적 계수를 구하였다. This paper is a basic study of the experimental results for the treatment of ammonianitrogen in the septic tank effluent. The substrates in this experiment are actual septic tank effluent and synthetic waste-water which is similar to septic tank effluent containing a considerable amount of nitrogenous component. Experiments were conducted for organic removal and nitrification using various recycle ratio and hydraulic retention time at each stage. The results obtained show that organic removal rate was above 80% in the 1st and 2nd stage, but as nitrification process was proceeded, above 90% of ammonia-nitrogen was removed in the 3rd and 4th stage. In these cases, the recycle ratio and HRT were found 30 and 7 hrs respectively. In the relation of NH₄^(+)-N removal to NO₃^(-)-N formation in the synthetic waste-water and septic tank effluent, when 1㎎/ℓ of NH₄^(+)-N was removed, NO₃^(-)-N formations were 0.95 ㎎/ℓ and 0.82㎎/ℓ respectively. And kinetics of nitrification using Biological Fluidized Bed was discussed also.

Adzuki bean is sensitive to waterlogging stress. The overall study on the waterlogging stress is limited comparing to the study on the drought and any environmental stress. Therefore, the present study was conducted to investigate the changes in growth characteristics and the expression patterns of proteins at the 5-leaf stage periods of adzuki bean. The domestic cultivar, Arari (Miryang No. 8) was used to test the waterlogging stress. In the waterlogging treatment for 3 days, the plant height showed slightly decrease in the treatment at 3 days of waterlogging, but root fresh weight showed significantly changes at 3 days of the waterlogging treatment. Chlorophyll contents showed also significantly different at 3 days of waterlogging treatment compared to control the plants. The waterlogging stress gradually influenced the growth differences between the control and the treatment respectively. More than 350 pro- tein spots were identified on 2-D gels using an image analysis. Moreover, a total of 28 proteins were analyzed using LTQ-FT-ICR MS. Among these 28 proteins, a total of 18 proteins were up-regulated, and 10 proteins were down-regulated under waterlogging treatment. According to biological process, the most of the proteins were found to be involved in carbohydrate metabolism. Regarding the subcellular local- ization, most of the proteins were localized into chloroplasts in 5-leaf stage.

Background: Several reports have suggested that the incidence of diseases caused by Group B streptococcus is increasing in nonpregnant adults, particularly those with serious underlying diseases. The objectives of this study were to define the clinical manifestations, underlying conditions(risk factors) of definite group B streptococcal diseases in nonpregnant adults and to obtain antimicrobial sensitivity of these infections. Methods: We analyzed the records of 274 cases of the Group B streptococcus isolated in Kyung-Hee University hospital between 1986 and 1993. Results: 1) Total Group B streptococcal isolates were 274 cases : Of these cases, 7 percent were 1 month of age or younger, 3 percent were older than 1 month but younger than 18 years of age, and 91 percent were 18 or older. 2) Men and nonpregnant women accounted for 87 percent (n=231) : 133 cases (57.6%) with definite infection, 46 cases(19.9%) with possible infection, and 52 cases(22.5%) with no infection. 31 cases of 133 (23.3%) nonpregnant adult with definite infection apeared to have acquired the disease nosocomially. 3) In the 133 nonpregnant adult patients, the most common clinical diagnosis were urinary tract infection(28%), and cervicitis(28%). 4) In the 133 nonpregnant adult patients, the underlying diseases or conditions were diabetes mellitus(32%), cerebrovascular accident(21%), hypertension(19%), renal failure(12%), and malignant neoplasm(5%), Sixty-nine percent of the cases had one or more underlying diseases. 5) In the antimicrobial sensitivity tests, 98.4% of isolates were sensitive to penicillin, 99.6% to cephalothin, 98,8% to cefamandol, 96.0% to erythromycin, 89.4% to clindamycin, and 49.4% to minocycline. 6) The case mortality rate was 4.5%(6 of 133). Conclusion:We found group B streptococcal infection to be a significant and apparently increasing cause of definite diseases in nonprognant adults, particularly in those with serious underlying diseases. Recognizing these infections early in the groups with serious underlying diseases will be helpful in lowering mortality.
