      • Effect of Meteorological Element on Growth and Yield of Sesame

        Kwon,Byung-Sun,Shin,Jeong-Sik,Shin,Jong-Sup,Choi,Seong-Kyu,Seo,Young-Nam 한국자원식물학회 2002 Plant Resources Vol.5 No.3

        This study was conducted to investigate the relationships between yearly variations of climatic elements and yearly variations of productivity in sesame. In addition, correlation coefficients among yield and yield components were estimated. The data of yield and yield components were investigated for 10 years from 1992 to 2001. The meteorological data gathered at the Yeosu Weather Station for the same period were used to find out the relationships between climatic elements and productivity. Yearly variation of the amount of precipitation in July and September were large with coefficients of variation(c.v.) of 64.59, 92.47%, respectively, but the variation of the average temperature in June and August were relative small. Yield and plant height greatly with c. v. of 26.24, 23.41 %, respectively, 1, 000 grain weights show more or less c.v. of 3.83% and length capsule setting show still less variation. Correlation coefficients between maximun temperature in period of cultivation(from June to September) and yield are positively significant at the level of 5.1 %, respectively. Correlation coefficients amount the plant height, length capsule setting, number of capsules per plant, weight of 1, 000 grains and seed yield were positively significant at the level of 1 %, respectively. Simple linear regression equations by the least square method are estimated for number of capsules per plant(Y₁) and the maximun temperature in August(X) as Y₁=10.1255+0.1725X, and for yield(Y₂) and the maximun temperature in August(X) as Y₂=21.6151 + 1.3724X.

        Grape vinegar(A) and grape onion vinegar(B) added (3% of onion juice) were produced through two stages of fermentation(alcohol fermentation and acetic acid fermentation) to increase the grape's use. Grape wine which contained 5.6% alcohol was produced on the 3rd day of first stage. Then through the second stages, grape vinegar, of which total acidity was 5.37% was produced. The quality of (A) and (B) which was produced through the two stages of fermentation was compared with the traditional grape vinegar(C,D) in the market. The content of sugar in (D) was a little higher such as 5.4 °Brix than others. That of (A) and (B) was 5.13, 4.98 °Brix respectively. The content of remaining alcohol in (C) was high such as 0.23% comparatively, But there was no remaining alcohol in (A) and (B). The content of acetic acid was 4.3~5.3% as a major organic acid of vinegars. The content of tartaric acid was 340.0 in (A), 316.7 in (B), 322.6 in (C) and 391.7㎎% in (D). The content of lactic acid was distinctly high such as 277.4㎎% in (D). There were differences such as 9.2~15.5㎎% in the content of total free amino acids among grape vinegars. (D) contained 15.5㎎% of total free amino acid and (B) also highly such as 12.0㎎%. Potassium was high in grape vinegars. The content of potassium, sodium and copper was higher in (A) than (B).

      • 리튬이 도핑된 막을 이용한 실리콘-실리콘 접합

        정지원,주병권,최우범,정성재,이남양,최두진,오명환 경북대학교 센서기술연구소 1997 센서技術學術大會論文集 Vol.8 No.1

        Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

      • Chloroform 용매 중에서 Aniline과 Iodine간의 Charge Transfer Complex 형성 Mechanism에 대한 연구

        권오윤,崔相元,金南政 여수대학교 1989 論文集 Vol.3 No.-

        The formation of charge transfer complex between indine and aniline in chloroform solvent have been studied kinetically by using conductivity method. The initially formed outer charge transfer complex was transformed into a inner charge transfer complex. The pseudo first order rate constants and aitivation entropy are affected by aniline concentration. The second order rate constants for the decomposition of the outer charge transfer complex(first order in aniline and in the outer charge transfer complex) depend on the aniline concentration. The ease with which the transformation proceeds depends on the relative magnitudes of the enthalpy of formation of the outer charge transfer complex as well as dielectric properties of aniline.

        불리언 질의 재구성에서 의사결정나무의 학습 성능 감도 분석

        윤정미,김남호,권영식 한국경영과학회 1998 한국경영과학회지 Vol.23 No.4

        One of the difficulties in using the current Boolean-based information retrieval systems is that it is hard for a user, especially a novice, to formulate an effective Boolean query. One solution to this problem is to let the system formulate a query for a user from his relevance feedback documents. In this research, an intelligent query reformulation mechanism based on ID3 is proposed and the sensitivity of its retrieval effectiveness, i.e., recall, precision, and E-measure, to various input settings is analyzed. The parameters in the input settings is the number of relevant documents. Experiments conducted on the test set of Medlars revealed that the effectiveness of the proposed system is in fact sensitive to the number of the initial relevant documents. The case with two or more initial relevant documents outperformed the case with on initial relevant document with statistical significances. It is our conclusion that formulation of an effective query in the proposed system requires at least two relevant documents in its initial input set.

      • 濟州産 柑橘醱酵酒 蒸溜酒의 熟成條件

        高正三,吳現道,高男權,姜順善 濟州大學校 亞熱帶農業硏究所 1992 亞熱帶農業硏究 Vol.9 No.-

        제주산 온주밀감을 이용하여 醱酵最適條件에서 얻어진 감귤주의 單式蒸溜하여 알콜농도를 43˚와 60˚로 조절한 다음 불란서산 참나무 술통재의 切片(1×1×3cm)을 浸漬 하여 熟成條件을 검토하였다. 알콜농도 60˚인 증류수중의 메탄올은 0.136g/100㎖, 알데히드는 4.07㎎/100㎖휴젤油는18.35㎎/100㎖, 에스테르는 27.03㎎/100㎖였다. 알콜농도가 높고 온도가 높을수록 참나무성분의 浸出이 잘 일어났으며, 단기간 熟成을 위해서는 다소 고온에서 熟成하는 것이 좋을 것으로 판단되었다. 숙성 pH는 4.1에서 색소침출효과가 좋았으며 자외선 처리효과는 없었다. 色素浸出은 온도에 많은 영향을 받고 있는 것을 알 수 있었으며, 官能檢査 결과 45˚, pH 4.1에서 6개월 熟成時에 외관 및 기호도에서 충분한 상품가치를 나타내었다. 감귤 브랜디의 경우 외국산 유명제품과 큰 차이를 보이지 않아 브랜딩기술의 확립과 熟成技術의 보완한다면 産業化에 대한 충분한 가능성이 있는 것으로 平價되었다. In order to produce citrus brandy made from Citrus unshiu produced in Cheju, aging conditions of citrus fine spirit with dipping oak chip were investigated. Citrus fine spirit prepared with simple distillation of citrus wine was adjusted to 43。 and 60。 alcohol concentration, and then three pieces of oak chip (1×1×3cm) was added to 300㎖ citrus fine spirit. The contents of methanol, aldehyde, fusel oil and ester were 0.136g/100㎖, 4.07mg/100㎖, 18.35mg/㎖ and 27.03mg/100㎖ respectively. The absorbance at 500nm of citrus fine spirit was increased with high alcohol concentration and high temperature. Color extraction from oak chip was mainly affected on temperature, and the effect of UV irradiation was not appeared. Compared with commercial Scotch whisky, citrus brandy adjusted to pH 4.1 and aged at 45℃ for 6 month was good in sensory evaluation.

        Two cases of primary small cell carcinoma of the ovary occurred. One was a case of 43-year-old woman associated with hypercalcemia and the other was a case of 40-year-old woman with pulmonary type. Ovarian small cell carcinoma of the hypercalcemic type have clinicopathological, immunohistochemical, ultrastructural, and flow cytometric features that from differ from those of small cell carcinomas of the pulmonary type. It is important for therapeutic reasons to distinguish these two types of ovarian tumors from each other and from a variety of malignant small cell tumors that ovary primarily or secondarily. So, we reported these cases with a brief review of the concerned literatures.
