황현진,장노순,이재홍 강원대학교 정보통신연구소 1998 정보통신논문지 Vol.2 No.-

This paper presents the efficient system architecture of a digital studio and its operation and maintenance. This paper shows the overview of the system components and explains their technical features in detail, and discusses system installation and operational test procedures. And then technical requirements and procedural schemes for system implementation have been proposed and the operational organization, training programs, and maintenance planning have been qeneralized and analyzed. It shows that essential points for constructing the optimum system are to follow a supply-demand curve of its markets and industries and to make technical innovations of system implementation. Training programs for system operators and administrators are also very important factors. The integration of such factors makes it possible to construct the efficient a digital studio.

Salicylaldehyde-Acetonitrile 非水溶媒中에서 亞鉛의 直流 Polarograph定量法

黃在順,黃三榮 全北大學校 基礎科學硏究所 1985 基礎科學 Vol.8 No.1

A method for the direct current polarographic determination of metallic zinc dissolved directly in organic solvent, salicylaldehyde, as metal-solubility in salicylaldehyde acetonitrile and 0.2M LiClO_4 supporting electrolyte, was studied. The solution of zinc was taken into a cell. After dried nitrogen gas was passed through it for 20 min. the direct current polarogram in the region of applied potential from 0.0-1.0V(vs. SCE) was recorded and all experiments was carried out at 25.0 ± 0.5℃. A reversible polarographic reduction wave was obtained and the reduction half wave potential was-0.56V(vs, SCE). Zinc was determined by refering to the calibraton curve.

국내외로부터 수집한 고추 유전자원을 포장에 재배하여 종자를 증식하는 동시에 주요 특성을 조사하였다. 헝가리에서 도입하여 1992년도에 평가한 계통들은 Hungarian Wax 혹은 Bell형으로서 바이러스에 심하게 걸려 우리포장환경에 잘 적응하지 못하였다. 1994년도에 평가한 계통들 중 브라질에서 풋마름병 저항성으로 도입한 KC350과 KC351은 직립성이며 바이러스에 강한 편이어서 매우 유망한 유전자원으로 사료되었다. 중국에서 도입한 KC376는 바이러스에 강한 편이며 대과를 착생하여 유망하게 보였다. 태국에서 도입된 계통들은 안동대에서 특성을 평가기록하였다. Accessions of pepper germplasm were planted in the field and their characteristics were recorded. Lines introduced from Hungary were very susceptible to virus diseases and as a result poor in adaptability in domestic field condition. KC350 and KC351 which were introduced from Brazil were growing errectly and tolerant to both bacterial spot and virus diseases. KC376, an introduction from China, was bearing large fruits with tolerance to virus. Introductions from Thailand were grown and evaluated in Andong Universiy, and major characters of them were recorded.

A method for the direct current polarographic and spectrophotometric determination of metallic iron dissolved directly in organic solvent, acetylacetone, was established. The solubility of metallic iron in acetylacetone was also observed in this study. Aliquots of 100mg sample dissolved in acetylacetone to the total volume of 100ml were used to determined the amounts of iron by direct current polarography in the region of applied potential from 0.1 to 1.0 Volt vs. SCE after bubbling for 20min. with nitrogen was recorded. A reversible polarographic reduction wave was obtained and the reduction half wave potential was -0.44Volt vs. SCE Iron was determined by refering to the calibration curve. After the observation of the various effects a calibration curve was prepared for 0.025-0.4mg/ml of iron in acetylacetone. A method established for the spectrophotometric determination of iron was as follows. A sample was dissolved in acetylacetone and one part of the above solution was diluted properly and the absorbance at 443mμ was measured. Iron was determined by refering to the prepared calibration curve. In another method, after the sample was dissolved in acetylacetone with (NH_4)_2S_2O_8 and diluted by H_2O, the absorbance at 443mμ was measured at pH 6.8. Iron was determined by refering to the prepared calibration curve. The new method developed in this study is useful to the rapid analysis of iron-content without the complicated courses needed prior to determination, and has accuracies nearly comparable to those attained the conventional method by ashing, evaporating and drying of the sample.

DC polarographic behavior of lron-Acetylacetone chelate in the Acetylacetone and 0.3 M NaClO_4 supporting electrolyte was studied in detail. The electrode reaction was found to be a reversible polarographic wave corrsponding to one electron reduction and diffusion controlled, and reduction half wave potential was -0.47 volt was. SCE ln this case, assuming that metal complex Fe(AA)_3 is reduced reversibly with one electron transter, the electrode reaction is given. as follows. Fe(AA)_3+e??Fe(AA)^-_2

全州工業團地 廢水汚染이 裡里, 益山地方의 用水質에 미치는 영향과 그 對策에 關한 硏究

黃在順 全北大學校 1979 論文集 Vol.21 No.-

Mangyung river is being contaminated by Jeon Ju stream, one of the major upstream of Mangyung river, which is being polluted by the sewerage of Jeon Ju city and the waste water from the plants located at Jeon Ju Industrial Area. In order to find out whether the water originated from MG river is harm, or not purpose of irrigation and home use, some indices such as PH, COD, BOD, SS, and DO were investigated at four adjacent regions of MG river. The results obtained in thisstudy are as follows ; 1. It is known that PH, COD, SS, and DO values of water of the upstream of MG river are 6.9ppm, 30.0ppm, 21.5ppm, and 9.5ppm, respectively. 2. The water originated from MG River was considered to be not harm for irrigation water, but harm for home use on the basis of indices regulated. 3. It is seemed to be desirable for the following countermeasures to be established to prevent water contaminations in these area. Firstly, it is desirable to construct sewers to seperate natural stream water from sewerage and waste water in these area. Secondly, it is desirable to construct more sewerage disposal plants and to expand the disposal facilities in these area. Thirdly, it is desirable to construct levees for Jeon Ju stream and Gosan stream to be separated.

이태준의 소설 『花冠』론 : 현실대응 논리를 중심으로

황순재 釜山大學校 1997 人文論叢 Vol.50 No.1

The aim of the study is to analyze the creative method of Lee Tae-joon's 『Hwa-kwan花冠』. This novel is a serial story in a newspaper which is announced in the latter half of the 1930's. He represented the logic of opposition of the day, embodimented of the popularity and the enlightenment through out the newspaper. Of course, his logic of opposition of the day has a negative reformism. But his opposit attitude will find in the typification of the object a subject of criticism. 1. He represented a course overcoming individuality. As a result, one can that the belief which became the foundation of productive character. The disillusive recognition to space corresponds to the course overcoming immaturity of the cognition about the reality. Also, the time continues in consecutive order, therefore he intended a serious consideration for the reality. 2. A course overcoming individuality extended to the penetration of the social life through positive recognition that is a denial and an admission. 3. The critical point of view anatomized tragic life which has Philistinism as an consciousness. Moreover, It is self-anatomy of the author's individualism and Philistinism.
