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.

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

人的 擔保制度의 課題와 展望

권용우,김영규 단국대학교 1999 論文集 Vol.34 No.-

This paper has examined the conditions for the personal security to fulfill its role of mediating of desirable credit dealings, and points out problems of the existing personal security system. Further this paper tried to present some reform schemes for this system. The Civil Code, in the articles 416 to 427, provides for the nine circumstances in which a cause produced between one of obligors jointly and severally liable and the obligee shall be absolutely effective against other obligors : the demand for performance, novation, set-off, release, merger, extinctive prescription, obligee's delay, the cancellation and extinction of contract. However in seems inadequate to give the Release absolute effect, in that, generally the obligee, who is expressing his intention of release, would exempt a specified obligor from his obligation. Therefore, it may be desirable to delete the Article 419. The Civil Code, in Book Ⅲ, which is refering to several obligees and obligors, stipulates only Joint and Several Obligation. However it gives us a confusion that the latter is the unique system of the several obligees and obligors. It would be, therefore, reasonable to insert an expressive provision concerning 'unechte Solidatita¨t' that has been recognized through doctrin and practice. Article 428 concerning the contents of suretyship obligation does not refer to the maximum suretyship(Maximalbu¨rgschaft). In realty, banks makes a contract for the maximum surety with the representatives of the companies in making advances, opening an L/C, concluding a suretyship contract, ect. It would be necessary to have this practice with a legal basis by establishing a paragraph that stipulates the maximum surety. This paper, finally, has dealt with the improvement for the system of personal reference. When we consider that the liability which follows the personal reference is excessively extensive ratione materae and ratione temporii, it would be necessary to prescribe expressly the collateral or complementary character of personal reference, and it would be also necessary to reduce the period of contract to two years.

권영규 위덕대학교 산업기술연구소 2005 산업기술연구소 논문집 Vol.9 No.1

SOI(silicon-on-insulator) 구조를 이용하여 고온용 압력 센서를 개발하였다. 압력 센서의 구조는 다이아프램(diaphragm)과 그 위에 배치된 전단 응력형 압저항으로 구성되어 있다. 개발된 압력 센서의 실온에서 사용 범위는 0-300torr, 압력감도는 75(㎶/V·torr)이며 최대 300℃까지 사용이 가능하고 압력감도의 온도계수는 -1,734 ppm/℃이다. 개발된 압력 센서를 이용하여 휴대용 압력계를 제작하고 그 특성을 분석했다. We have developed the semiconductor pressure sensors which can be used in the high temperature environment by using the SIMOX(Separation by IMplanted OXgen) SOI(Silicon on Insulator) wafer. The pressure sensor structure is composed of a diaphragm and shear stress type piezoresistor which layed on the diaphragm. The high temperature pressure sensors show the excellent characteristics as follows : The pressure sensitivity is 75(㎶/V·torr) and the pressure range is 0 to 300torr at the temperature of 20℃. Moreover the pressure sensors can be operated up to 300℃ and the temperature coefficient of the pressure sensitivity is -1,734 ppm/℃. We have produced a portable pressure gauge using the developed pressure sensor and analysed its characteristics.

오존처리에 의한 하수슬러지의 감량화

The effects of ozone treatment on the dewaterability of activated sludge wasted from a sewage treatment plant were investigated in this study. Following ozone treatment, sludge was dewatered using a pressure fitter. The sludge filterability evaluated by SRF deteriorated with ozone dosage at relatively low ozone doses due to sludge solubilization and particle size decrease. However, at ozone doses higher than 0.6gO_3/gSS, the SRF of the ozone treated sludge became comparable with the value for the sludge without ozone treatment. It is suggested that the oxidation of the viscous, high molecule organics attached at cell surface reduces the surface charge of sludge particle and promotes flocculation at relatively high ozone doses. Ozone treatment also cause the release of bound water trapped inside cells or flocs, resulting in significant reduction of cake water content after dewatering. In terms of cake volume, more than 70% reduction was obtained at 0.6gO_3/gSS. These observations suggest that ozone treatment has potential to significantly enhance sludge dewaterability and to produce a more compact cake without severe deterioration of its filterability.

Site characterization is one of the most important performances in projects with regard to solving geotechnical problems. Piezocone penetration test is a fast, economic, and accurate method of site characterization. Static cone penetrometer and the piezocone represents the most versatile tools currently available for soil exploration. The cone penetration and piezocone tests provide continuous sounding capability and repeatability. Rare of consolidation parameter may be assessed form the Piezocone test by measuring the dissipation or decay of pore pressure with time after a stop in penetration. And many researches have been developed to determine the horizontal coefficent of consolidation from the Piezocone test. Many of these researches using a theoretical solutions which is determined from either the cavity expantion theory or the stress path method. However, depending on assumptions and analytical techniques, the results can be varied considerably. For that reason, many researchers make their effort to improve and complement the defect of already established methods. In this dissertation, the correlation between the Coefficient of Consolidation from Piezocone dissipation test and the Coefficient of Consolidation Rowe Cell horizontal consolidation test in many cases was studied. The purpose of this study is to know the changing of the Coefficient of Consolidation by loading condition while Rowe Cell horizontal consolidation test is used

콩의 증자조건에 따른 검정콩 전통간장의 숙성 후 유리당, 유기산, 지방산조성을 조사하였다. pH 값은 5.04~5.32로 시험구간의 큰 차이를 나타내지 않았고, 원료 콩을 상압증자한 검정콩 간장이 가압이나 스팀보다는 약간 높은 수치를 나타내었다. 적정산도는 4.26~7.73mL로 나타났으며, 가압증자한 검정콩 간장(4.26~5.61mL)이 가장 높았으며, 다음으로 상압(7.32mL), 스팀(5.99~6.96mL)의 순으로 나타났다. 환원당은 25.18~194.81㎎%로 나타났고, 상압이 25.18㎎%로 가장 낮았으며, 가압이나 스팀증자한 검정콩 간장의 경우 상호간에는 큰 차이가 없지만, 상압한 것보다는 7~8배 높은 함량을 나타내었다. 주요 유리당은 glucose, fructose, xylose였으며, 스팀증자한 검정콩 간장이 상압이나 가압보다 각각의 유리당 모두가 많았고, 상압증자는 유리당이 극히 미량으로 검출되었다. 주요 유기산은 succinic acid, oxalicaicd, tartaric aic, malic acid, citric acid였고, 총 유기산은 스팀증자 (40.38~76.96 ㎎%)한 검정콩 간장이 상압(55.85㎎%)이나 가압(27.78~34.21)한 것보다 많았다. 증자 처리시간이 길수로 가압과 스팀으로 처리하여 제도된 검정콩 간장은 약간씩 감소되는 경향을 나타내었다. 주요 지방산은 palmitic acid(33.28~43.51%), stearic a창(14.15~19.16%), myristic acid(5.03~19.14%)였으며, 전체 지방산 중에 55.97~72.85% 비율을 차지하였고, 원료 콩에 존재하지 myristic acid가 상당히 많이 존재하였다. pH values in all samples were in the range of 5.04 to 5.32. pH of kanjang prepared with normal pressure(HPK) was higher than that of kanjang prepared with high pressure(HPK) and kanjang prepared with steam(SPK). Titratable acidity(TA) in all samples were found to be 4.26∼7.72 mL. TA in HPK(5.99∼6.96 mL) was lower than that in SPK(4.26∼5.61 mL) and NPK(7.32 mL). Reducing sugar(RS) contents in all samples were in the range of 25.48 to 194.81 ㎎%. Rs contents of HPK and SPK were a similar pattern and were higher than that of NPK. Major free sugars(FS) were glucose, fructose and xylose. In total FS, SPK was higher than that of NPK and HPK. Major organic acids(OA) were succinic acid, oxalic acid, tartaric acid, malic acid citric acid. OA contents in HPK and SPK were decreased slightly according to the heating time of whole black bean. The highest percentage of fatty acid(FA) in all samples was palmitic acid(33.28∼43.51% as area % of GC chromatogram), followed in a decreasing order by stearic acid(14.15∼19.16%) and myristic acid(5.93∼19.14%). The composition ratios of three FA to total FA ranged from 55.97 to 72.85%. In all samples, there was myristic acid that was not contained in raw soybean.
