公共經濟學의 本質

李永範,李龍三 大邱大學校 社會科學硏究所 1997 社會科學硏究 Vol.4 No.2

現代資本主義는 民間部門(private sector)과 公共部門(public sector)으로 이루어진 混合經濟(mixed economy)이기 때문에 私的財와 公共財가 生産, 消費되고 있다. 특히 公共財는 等量消費, 結合供給, 非排除性과 非競性의 特性을 가진다고 볼 수 있다. 이러한 公共財의 需要와 供給을 다루며, 混合經濟에 있어서의 政府部門의 經濟活動을 연구하는 것이 公共經濟學이라고 할 수 있겠다. 따라서 公共經濟學은 政府活動과 社會全體의 經濟的 關係를 연구하는 것이며, 政府行動의 理論과 公共經濟問題를 종합적으로 다루는 것이다. 그리고 公共經濟學은 公共經濟問題를 사회가 어떻게 해결하는가 하는 實證的 公共經濟學과 어떻게 그 문제를 해결하여야 하는가를 다루는 規範的 公共經濟學의 兩面을 갖는다고 하겠다.

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

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.

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.

During the last two'decades the nation has experienced a drastic change of the nation-wide spatial features. The economic expansion of the industrial bases in general and the dynamic growth of manufacturing in particular have persisted in the process of a series of economic development schemes, along with the physical land plans, resulting in the phenomenal transformation in the existing spatial framework of the nation. Especially, the construction of the national expressway networks was a propellent for changes in the various facets of the environment, physical and socio-cultural. Even though the highway network, together with facility of communication system, has helped to speed up the flow of the man and goods among region, it has been also as factor for the regional development in the typical rural hinterland. It is assumed that once a new highway is built up, the people in nearby area affected by the barrier of physical environment will receive many facets of environmental impacts in daily life. One of its positive side-effects is the increase of opportunities in terms of social and economic activities, because people, set free from the physical barrier, are provided with the easy access for information and movement. This paper is primarily concerned with the finding of the perceived behavioral modes in a typical from communities in relation to the utilization of the central places; it is also aimed at providing some useful information of socio-economic status in the physically isolated rural area by which a new highway under near completion will be passed. Geochang-gun(郡) was selected for the case study. Tweleve sruvey units, of which one unit consisits of 18 subitems, were selected to obtain the broad scales of socio-economic data through interview with residents to see how activity or perceived activity is related to the basic socio-economic structure and how people respond to their needs of certain services such as education, shopping movement of residents, choice of place for jobs. Some characteristics found out through the analysis can be as follows. First, Geochang-gun belongs to an isolated rural society with dominant mode of farming activity in which the traditional value of life is prevalent but the changes in the socio-economic environment loom through diffusion of innovation. Second, it seems that most farming communities have faced the trend of population decrease due to outmigration toward urban areas while Geochang-eup(邑), a central place town, has shown the opposite effect for its strong tertiary industrial activities. Third, it is identified that Geochang-eup has played more important central place functions relative to its comparable counterparts in the size of population because of lack of compective towns or cities at the perimeter of the 50km radius. Fourth, in relation to the perceived level of familiarity for neighbor cities, people seem to be biased toward such factors as distance from cities, functions respective city provides, centrality of each and presence of kinfolks and friends. Perceived levels for neighbor cities appeared in the order of Daegu, Busan, Seoul and Junju. Fifth, as regard the perception for resident movement, it seems that people are directly influenced by personal motive personal experience as to the purpose of movement, the time-interval for residence, the nature of movable place and distance. The preferred place for seeking jobs wes choiced in the order of Busan, Daegu, Seoul, Geochang-eup and Jinju whereas the desirable place for the higher education appeared in the order of Daegu, Seoul and Jinju. Sixth, according to the analysis of utility of central place facilities based on 4 class of 15 items, most people have been relied on Geochang-eup Daegu city for meeting their needs for services. Daegu shows more acceptance in the highest order functions in the hierarchy, while Geochang-eup receives a broad scale of preference in the upper three order functions and village centers dominate the fourth order function. Seventh, it is identified that the social status of the local residents reflects the differences in th preference of the central place. As a result of this basic analysis, it is felt that the present paper serves a useful but limited purpose by drawing attention to the behavioral aspects of social environment which need to be through investigated in the follow-up research in the near future.

We studied on the sod culture at apple orchard from 1968 to 1970. The results obtained can be summarized as follows; 1. There was no difference in the soil temperature between 20 and 40cm. In the sod lopt. But the change of soil temperature in the control plot was remarkable. 2. It was showed that the moisture content was a average 44.7% in sod polt, and 41.0% in control plot. In Weed plot its content was 49.1%. It showed the highest content among sod plots. Comparing this result with first and second year experiment, there was difference meaningly in the soil moisture but no striking difference between third and second year xpeeriment. Soil moisture content was maintained nearly the same amounts after two years from the experiment. 3. Sods produced was 34.5㎏/10m in Weed plot while in orchard grass plot was 15.0㎏/10m. 4. Root elongation of apple tree was 58.3㎝/year in Ladino clover plot, 32.9㎝./year in Weed plot in turn. 5. Shoot elongation of apple tree was 57.6㎝./year (in Ladino clover plot, 57.5㎝./year) in weed plot and 48.8㎝./year in control plot. Shorter by 9㎝. than weed plot. 6. N.P˙ and K. content in the apple leaf was satisfied for the tree growth, and CaO and MgO were also satisfied. During August when fruit and flowed buds are developing, these elements were reduced somewhat. 7. Organic materials are increased at sod plots than control plot. By accumulation of sod in the soil, organic materials and MgO were increased. Ladino clover and Weed plots were 1.09% and 1.04% in MgO element respectively by high amounts of sod production.

The differences of the liver scintigraphic features between postnecrotic and nonpostnecrotic liver cirrhosis were studied for 69 patients. Degrees of mottling and splenomegaly were no different between two groups but shrinked form was more frequent finding in postnecrotic type(23:10), and normal shape & enlarged left lobe with shrinked right lobe were relatively dominant in non-postnecrotic group(15:6, 10:2). Grade of extrahepatic uptake of ^99mTc-tin colloid was significantly higher in Child-Pugh B & C group than A group(p<0.05), but there was no difference between postnecrotic and non-postnecrotic groups. These will be important results on the dicision for the presence of cirrhosis according to the variable causes.

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.
