Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

대나무를 纖維工業의 原料로 利用하기 僞하여 竹粉 시멘트의 水化反應을 木質-시멘트 및 製紙슬러지-시멘트와 比較하여 測定하였다. 水化反應 促進을 위한 化學添加劑로는 CaCl_2와 MgCl_2 그리고 NH_4Cl을 시멘트 重量當 3%를 各 試驗片에 添加하였다. 또한 無處理時의 各 試驗片과 化學添加劑를 使用한 名 試驗片의 結晶形態 및 結晶構造를 調査하기 僞하여 走査電子顯微鏡으로 斷面을 測定하였다. 無處理時의 境遇, Henon bamboo, Moso bamboo 및 Giant timber bamoo는 전혀 水化反應을 보이지 않았으며, 化學添加劑를 利用한 境遇에는 木質水準으로 水化反應이 나타나 竹紛을 利用한 시멘트와의 水化反應은 使用해야 함을 알수 있었다. This study was examined on hydration of bamboo meal-cement composite. In a separate experiment, the heat of hydration generated from the bamboo meal (wood meal and paper sludge) - cement - water system was measured, and Moslemi's inhibitory index was caluated from the results. To improve the hydration of bamboo meal- cement, a series of experiments were conducted with the addition of various chencal additives such as calcium chloride(CaCl_2 ), magnesium chloride( MgCl_2 ) and ammonium chloride (NHCl) The amount of chemical additives was 3% based on the weight of the cement. A scanning electron microscope (SEM) was used to examine the crystallization of cement and bamboo meal ( wood and paper sludge ) - cement composite. These species , Henon bamboo, Moso bamboo and Giant timber bamboo were proved to be highly inhibitory in a series of hydration tests. The addition of chemical additivies, especially calcium chloride and magnesium chloride, appears to enhance compatibility in bamboo meal-cement-water composite.

본 시험은 크릴 분말의 사료적 특성을 조사하고, 산란계 사료에 첨가하였을 때 계란의 생산성과 품질을 비교하기 위하여 수해하였다. 크릴 분말을 산란계 사료에 0, 1 및 2% 수준으로 첨가하여 216수에 6주간 사양시험을 실시하였다. 크릴분말의 일반성분은 수분 8.25%, 조단백질 50.52%, 조지방 16.67%, 조회분 15.72%로 단백질과 지방이 높은 동물성 사료원료였다. 그리고 무기질(15.72%), astaxanthin (10ppm) 및 콜레스테롤 함량 (780ppm) 또한 많았다. 산란율, 연파란율, 일일사료섭취량 및 난중은 처리간에 유의적인 차이가 없었다. 황고 및 난황색도는 크릴의 첨가수준이 높을수록 유의적으로 높아 산란계의 난질을 향상시키는 첨가제로서의 가능성을 보였다. 이상의 결과를 볼 때 크릴 분말은 단백질과 지방이 높은 동물성 사료이며, 산란계에서 천연착색제로의 가능성을 보였다. This experiment was conducted to evaluate the chemical composition of Antarctic Krill(Euphausia superba Dana) meal as feed, and to investigate the effect of its supplementation on productivity and egg quality of laying hen. A total of 216 layers at the age 43 weeks in commercial cage were fed for 6 weeks with 3 different diets containing 0, 1, and 2% Krill meal (KM). The chemical composition of KM was consisted of moisture 8.25%, crude protein 50.52%, crude fat 16.67%, curde ash 15.72%, indicating that KM contains large amount of protein and fat. Krill meal also contains large amounts of mineral(15.72%), astaxanthin(10ppm) and cholesterol(780ppm). No differences were found in egg production, broken and soft eggs, and feed intake among treatments. Dietary supplementation of KM resulted in increased egg yolk height(6.1㎜) and yolk color (2) compared with those of control, suggesting that KM can be used as a feed additive for yolk quality improvement. According to the results of this study, Krill meal can be supplemented in laying hen diets as protein and fat sources, and natural coloring pigment.

This experiment was carried out to investigate the hydration of Hanji sludge-cement composite. The percentage of Hanji sludge per cement is 7.5, 15 and 30% respectively. The results indicated that the Hanji sludge of 7.5% had the most effect on hydration than any other specimens. Hanji sludge (Ⅱ),(Ⅲ) and Larix leptolepis(Sieb. et Zucc.) Gorden were proved to be highly inhibitory in a series of hydration tests. The addition of chemical additives, calcium chloride(CaCl_2) appears to enhance compatability in cement-wood-water mixes.

Gaseous effluent emitted from the excrements of domestic animals were qualitatively analyzed by gas chromatography using PEG colume. The major organic compounds emitted from the excrement of the chicken were identified to be methyl ethyl ketone, secondary butylalcohol, ethyl isobutanoate, and otehrs. In the pig excrements, however, propionic acid, isobutyric acid, paracresol, and others were detected. The composition of the emitted gas was, changed depending upon the sampling time. Malodors from the excrements of the domestic animals were studied. Deodorization of ammonia which affects to odor strength could be obtained by means of the chemical oxidation utilizing KMnO_(4), H_(2)O_(2), NaOCl and H, O_(2) -NaOCl.

In order to evaluate characteristics of bast fiber, the types and the cell wall properties of various bast fibers originated from Broussonetia kazinoki Sieb. Morus alba var, romana Loddiges, Edzeworthia papyrifera Sieb. et Zucc. and Wikstroemia irichotoma makino. In the other hand, Broussonetia kazinoki Sieb. et Zucc. and Wikstroemia trichotoma Makino. The pits were not find in fiber surface of bast fibers from 4 species, but the presence of secondary wall was surely confirmed. The cell wall structure of bast fiber was a little different from that of wood fiber.
