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

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.

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.

Aqueous urethane dispersion resin begins to assume commercial importance due to increasing environmental awareness of VOC in coating industry. Moreover there have been strong industrial needs for the development of reactive-type polyurethane flame retardant coatings. In this study, chlorinated polyester polyols were synthesized by two step polycondensation reaction using various chloroacetic acid, adipic acid, trimethylol propane, and 1,4-butanediol. In the next step polyurethane dispersion was prepared using these chlorinated polyester polyols and isophorone diisocyanate with dimethylol propionic acid(DMPA) and trimethylamine. The structure of chlorinated polyol was characterized by GPC, FT-IR and NMR. Particle size and its distribution were examined in term of various dispersion parameters including molecular weight and composition of polyol, amount of DMPA, and NCO/OH ratio, etc. The effect of chlorinated polyols on flammability and physical properties was also evaluated.

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.

C.Tilly의 역사사회학적 사회운동모델과 이론적 지향성

權圭植,康榮漢 慶北大學校 1989 論文集 Vol.48 No.-

Traditionally, theories that attempt to explain social movement behavior were collective behavior approaches. But the movements of 1960s dramatically challenged these kinds of approaches. That is, resource mobilization theory has recently presented an alternative interpretaion of social movements. This new perspective now occupies a centeral place in social movement theories. Major concerns of this paper are to analyze C. Tilly's mobilization model of social movement which is one of these perspectives and review his theoretical orientations. In order to pursue these concerns, this paper has been divided what follow into five sections:Ⅰ. Preface, Ⅱ. The components of social movements, Ⅲ. Mobilization model, Ⅳ. C. Tilly's theoretical orientations, Ⅴ. Conclusions. Tilly has summed up the findings of his diverse test and more general historical investigations under the rubric of the "mobilization model". The elements of the model are organization, interest, represion, power,opportunity, and collective action. According to the model, the main determainants of a group's mobiliation are its organization, its interest in possible interactions with other contenders, the current opportunity for such interactions, and the group's subjection to repression. The extend of a contender's collective action is a product of its power, its mobilization, and the current opportunities and threats confronting its interests. The dominant parts of the model are mobilizaion, collective action, and opportunity. These three elements have been the focus of Tilly's historical research. In another side, what are Tilly's stheoretical orientations? That will be the general attitude of the analyses to follow: doggedly anti-Durkheimian, resolutely pro-Marxian, but sometimes indulgent to Weber and sometimes reliant on Mill.
