李龍三,尹晟鐸 濟州大學校 亞熱帶農業硏究所 1989 亞熱帶農業硏究 Vol.6 No.-

本 試驗은 TPT-8, UPS-63을 공시하여 定植時期에 따른 winged bean의 種實收量과 green pod 收量 그리고 이들의 수량구성요소를 조사하여 적정 정식기를 구명코자 시험하였던 바 그 결과를 요약하면 다음과 같다. 1. 種實收穫區 및 green pod 收穫區 모두 開花所要日數는 정식일이 늦을수록 단축되는 경향이었으나 開花期는 거의 비슷하여 長日性植物로 판단되었다. 2. 定植期間 種實收量을 보면 5월 30일 定植期가 가장 수량이 많았으며 같은 정식기의 UPS-63이 185kg/10a로 가장 수량이 많았다. 3. 定植期間 green pod 收量은 5월 30일 定植期가 가장 수량이 많았으며 가장 수량이 많았던 구는 5월 30일 정식구의 TPT-8로 1834.3kg/10a이었다. Two varieties, TPT-8 and UPS-63 with three transplanting date of May 1, May 15 and May 30 were tested to determine optimum transplanting date of winged bean (Psophocarpus tetragonolobus (L.) DC.) in relation to seed yield and green pod yield. The results obtained are summarized as follows; 1. Days from planting to flowering were shorter as transplanting date got later in both seed harvest trial and green pod harvest trial. But flowering date was about the same time, indicating that winged bean is long-day plant. 2. Among transplanting dates, May 30 transplanting date yielded the highest seed yield and UPS-63 in the same transplanting date showed the highest seed yield by 185.0kg/10a. 3. Among transplanting date, May 30 transplanting date also yielded the highest green pod yield and TPT-8 in the same transplanting date obtained the highest yield by 1,834.3kg/10a.

Using the colorimetric [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) assay, we evaluated the chemosensitivity of 8 anticancer drugs{vincristine(VCR), vinblastine(VBL), adriamycin(ADR), cisplatin(CPDD), etoposide(VP-16), cytosine arabinoside(ara-C), bleomycin(Bleo) and cyclophosphamide(CYC)} and the cytotoxicity-enhancing effects of (±)-ar-turmerone and the extracts of the crude drugs {Lithospermum erythrorhizon(LE) and Scutellaria baicalensis (SB)} on the above mentioned anticancer drugs against HL-60 and KG-1 cells among 8 anticancer drugs, VCR, VBL, ADR, and CPDD inhibited the growth of both cell lines by more than 50%, while VP-16, ara-C, Bleo, and CYC were less effective. (±)-ar-Turmerone had significant inhibitory effects against both cell lines, showing the ID_50 values of 11.730 ㎍/㎖ and 0.292 ㎍/㎖ for HL-60 and KG-1 cells. respectively. But the extracts of LE and SB roots showed no significant cytotoxic effects. According to ID_50 values, the cytotoxicities of VCR, VBL and ADR against HL-60 were enhanced two, eight and three times by mixing (±)-ar-turmerone, five, seven and three times by adding the extract of LE root, and twenty, six and three times by mixing the extract of SB root, respectively. The cytotoxicities of the above mentioned drugs against KG-1 cell were enhanced two, seven and three times by mixing (±)-ar-turmerone, two, three and three times by combining with the extract of LB root, and two, five and two times by adding the extract of SB root, respectively. The cytotoxicity-potentiating effects of (±)-ar-turmerone and the extracts of LE and SB roots againg HL-60 cell were greater than KG-1 cell.

地方工業立地를 통한 農村地域人口 定着에 관한 硏究 : 晋州一帶 工場從業員 調査를 中心으로 Based on the Result of Questionaire Survey to the Factory Employed in Chinju and its Vicinity

李成浩,崔三鎔 부산대학교 사회과학대학 1985 社會科學論叢 Vol.4 No.2

Recently, the drastic decrease of population in the rural areas has emerged as a serious issue. This trend, stemmed directly from the phenomena of urbanization following the high rise industrialization, can be to some extent blamed on the existing direction of both the economic and regional development policy. Namely, the development scheme, based on the manufacturing-led growth center model Korea has pursued since 1960s, has brought about the relative stagnation in the rural part of the nation, causing naturally the outmigration of rural population into the urban areas. The rural decline ensued from the successive population drain entails various aspects of the negative impacts, such as the wide range of interregional income disparities which may disrupt the national consensus of the nationhood and raise the dual structure in the physical land space. This paper, viewed from the above problem statement, is aimed at analyzing the effect of the case of inducing the factories into the rural areas as a development strategy for the efficient rural settlement of population and also investigating the status of the present rural manufacturing to identify what is required to support such project. The manufacturing employed from 10 factories in Chinju and its vicinity, consisting of 573 people, was sampled for conducting the case study. Questionnaire survey sheets were given to each respondent to obtain the relevant ranges of socio-economic data relating to his or her work-place and its condition; survey items contain such information as family status, dwelling and its tenure, education, income, transport means for journey to work, and conditions of workplace and jobs. Main findings confirmed through the analysis can be summarized as follows. First, as the result of the analysis on the past trend of population movement, it is identified that the phenomena of the increase and decrease of population has a close relation to the regional distribution of industries. Second, it is revealed that the male is aged higher than the female; the married has the higher portion than the non-married. Third, it is shown that most of the manufacturing workers have the low level of monthly income and educational background. Fourth, it is indicated that some variables such as the present address, the birth place, the place of final education, and the dwelling place before taking jobs have intimate relationships with each other; it also appears that in view of no evidence of taking the present job to be a factor of population movement, the setting up of factories in the rural areas can't be a component of population migration. Fifth, it is found that the level of satisfaction of the present job varies on the basis of job training experience and the level of monthly income. Accordingly, in order to encourage rural people to take a job in the present place, it is apparently necessary for creating the job training programs for procurement of the job-related technical license as well as taking some policy measure to improve the existing wage systems. Sixth, it is also found that the rural area has still the potentiality to provide quality of labor forces for its own manufacturing operation, that is an important factor for the rural base factories to be managed in the better direction. Seventh, it is identified that most of the respondents have the commuting distance of 12km or less and the time range of one hour or less, for journey to work; the best desirous mean of transport for factory workers can be the commuting by the walk, the bicycle-riding, and the commuting bus provided by the firm. Eighth, in conclusion it should be pointed out that the success of population settlement in the rural area through the localized manufacturing bases depends upon the common effort by the rural residents, the entrepreneurs, the central government, together with precarious choice of the relevant establishments at the proper scales of the operating units on which procurement of raw materials and search for markets are relied.

韓國經濟開發計劃과 財政의 役割 : 1962∼'71

李龍三 大邱大學校 社會科學硏究所 1998 社會科學硏究 Vol.5 No.1

韓國은 1960年 1人當 GNP가 $79에 불과한 빈곤한 國家였으며 그때의 輸出은 $3,290만 인데 輸入은 그 10培인 $35,400만이었기 때문에 外國의 資本이 없으면 經濟活動을 제대로 할 수 없었다. 이와 같이 美國을 비롯한 외국의 援助가 감소됨에 따라 政府는 外國의 資本을 도입하는 經濟開發5個年計劃을 세워 自立經濟의 確立을 목표로 하였으며 이러한 經濟開發計劃을 성공시키기 위해서는 무엇보다 財政運營의 役割이 중요하였다. 특히 經濟開發에 중점을 둔 財政投融資 活動은 경제성장에 지대한 영향을 미쳤다고 할 수 있다. 따라서 본 논문에서는 한국경제개발계획에 있어서 중요한 기능을 한 재정의 경제적 역할을 살펴보고자 하는 것이 목적이다.

Although the Working Formulation is commonly used to classify NHL in Korea, it has been recognized as imperfect for primary extranodal lymphoma, expecially for patients with nasal, paranasal disease because of their histological characteristics. Angiocentric T/NK cell lymphoma remains rare clinical presentation in North America and Europe but is more common in Asia and Latin America. The optimal mode of treatment has also not been decided on, probably because of their rarity and limited understanding of its natural course. The aim of this study was to analyze our experience with 14 patients with angiocentric lymphoma seen at the Chungnam Natioanl University Hospital over the last 5 years. We reviewed the records of 14 patients who were treated at the Chungnam National University Hospital between January, 1996 and December, 2000. The angiocentric T/NK cell lymphoma accounted for about 8.2% of NHL. The median age was 52.5 (range 36-71) years. Sex ratio was equal. According to the Ann Arbor staging system, disease was classified as stage Ⅰin 3 patients, stage Ⅱ in 8 patients and stage Ⅳ in 3 patients. Systemic B symptoms were present in only four patients in only four patients. All patients has extranodal involvement. The most frequently involved extranodal sites were nasal cavity followed by paranasal sinuses and orpharynx. The most common presenting symptoms were nasal obstruction with purupent rhinorrhea followed by dysphagia. According to the International prognostic index (IPI), most patients was in low-risk group (11 patients). Nine patients responded completely. Seven patients were received combination chemotherapy and 2 patients had radiation therapy as a initial treatment. Five patients were relapsed. After a median follow-up of 660.5 days, the overall survival and disease-free survival rates at 3 years was 56.8% and 42.9% respectively. The median survival time was not yet reached. The median overall survival time was 1338.5 (range 1212-1564) days for non-relapsed and 733.4 (range 302-1008) days for relapsed patients. The median time from CR to relapse was 100.5 (range, 39-159) days. There were limitations to know enough about the characteristics of angiocentric T/NK cell lymphoma because of a small number of patients. In the future, multicenter trials will be neccesary to identify clinical characteristics, optimal treatment mordalities and their responses, and prognostic factors.

The results of sod culture from 1968 to 1969 can be summarized as follows: 1) In weed plot, the average soil temperature was 21.2℃ under the Roll's janet tree while the average temperature of orchard grass plot was 22.3℃. Red clover plots under and immediately surrounding Jonathan tree had the highest average soil temperature. The average temperature was 2-3℃ lower during the second year than the first year. The temperature of the control plot was 1 to 2℃ higher than that of the sod plot. The soil moisture content beneath Roll's janet tree was 49.0%, while the moisture content beneath Jonathan tree was 44.4%, both of which represent an 8% increase over last year. At the same time the orchard grass plot had a higher soil moisture content than both Roll's janet and Jonathan. 2) The fresh weight of the sod produced was the highest in the Ladino clover plot at Roll's janet and Jonathan orchards, whose sod fresh weight were 110.6Kgr and 113.7Kgr respectively. The fresh weight increased three times this year over last year. 3) Shoot elongation was the longest in the Ladino clover plot at 86.1㎝ while the control plot which showed the longest elongation in 1968 was retarded severely in 1969. 4) Due to the cutting of the sod, N.P. and K were increased but after one month the total content of N.P.and K decreased because of absorption of these elements by the tree. 5) Organic materials were highest in the Ladino clover plot of both the Roll's janet and Jonathan orchards, 1.82% and 2.28%, about 0.5-1.0% higher than the control plot. * Sod culture was better than clean-tillage culture for the following reasons. 1) The soil temperature of the sod plot was higher than the control plot by 1-2℃. 2) The sod plot contained 8% more moisture than control plot. 3) Shoot elongation of the sod plot was longer than that of the control plot. 4) There was more N.P. and K in the sod plot than control plot. 5) There was 0.5-1.0% more organic materials in the sod plot than in the control plot. * Comparision of the results between the sod and weed plot: 1) The sod plot was 2-3% higher in moisture content than the weed plot. 2) The sod plot produced 10-30kgr more weight of sod than the weed plot. 3) Shoot elongation of the sod plot was 5-8㎝ longer than the weed plot. 4) N.P. and K elements were 0.5-1.0% higher in the sod plot than in the weed plot. 5) Accumulation of organic materials in the soil was 0.5-1.0% higher in the sod plot than in the weed plot.
