The results of individual PAH source profiles that can be applied to receptor model are as follows. The sum of 16 PAH concentrations was 391.41 ng/S㎥ in a tunnel. Phenanthrene was the most abundant compound among 16 PAH, and then pyrene, fIuoranthene, anthracene, and naphthalene can be seen in elevated contents. 11,056.61 ng/S㎥ of 16 PAH concentrations in BC oil boiler was two times higher than 6,582.57 ng/S㎥ of those in LNG boiler. Naphthalene was the most abundant compound in both facilities. Phenanthrene, anthracene. and acenaphthylene were the second dominant compound group in order from both facilities. BC oil boiler had relatively high concentration of pyrene compared to LNG boiler that had high concentration of fluorene and did not detect pyrene. The sum of 16 PAH concentrations emitted from MSW incinerators after APCD (air pollution control device) was three times higher than those from MSW incinerators bcfore APCD. However, the concentrations of more than 4-ring PAH compounds (e.g., benzo (a)anthracene) before APCD were higher than those after APCD. This fact implies that PAHs generated by combustion process are eliminated in APCD and they are continuously produced in stack or atmosphere by PAHs precursors.

Aricultural credit can contribute to the improvement of net income of a farm business by helping to create an adequate size, increase efficiency, adjust to changing technology and prices, meet seasonal fluctuations in income and expenses, protect the farm adverse conditions through maintenance of a credit reserve, and provide business continuity. In recent years, technological revolution has brought about several significant changes in the structure of agriculture. The substitution of physical capital for labor and the increased use of purchased inputs has created a need for substantially more funds both in the aggregate and in a per farm basis. Over time, in spite of increasing fund demand, profit margins in agriculture have been declining steadily, so farmers have become in creasingly dependent on outside sources of fund. That has weighted interest burdens for farms. Specially, because the rate of interest charged on loans depends on following factors the lenders cost of fund; the default risk and market risk involved in the loans; loan serving costs; and inflation, which causes the real rate of interest to be less than the nomial rate the interest burdens of farms are very serious. Therefore in order to continue efficient farm management through agricultural capital formation, it is necessary that farms should increase productivity of agriculture and farm household savings. In addition, at the policy level, it is necessary to raise the rate of agricultural growth and real income within the agricultural sector to reduce the usurious farm liabilities.

In Korea, leaf tobacco farming has been carried out principal role in agricultural production and management. However, the production of leaf tobacco has been faced with crisis in proportion as decreases of agricultural labor and opening of world tobacco market. Therefore, to strengthen the competitive power in price and quality, it is necessary that we should be improved agricultural structure through mechanization and cost reduction in leaf tobacco farming. The principal objective of this study is to find out the strategies of mechanization and the directions for rationalization of management in leaf tobacco farming. The results obtained from this study were summaryzed as follows. 1. Size of cultivation land per farm household in leaf tobacco farming has been rapidly enlarged in according as the decrease of farms. 2. The principal points of mechanization in leaf tobacco farming are to decrease machinery utilization cost, increase production, and save labor. To increase physical and economic efficiencies of machinery utilization in leaf tobacco farming, it is necessary to enlarge farm size through centralization of production districts. 3. The rising production cost of leaf tobacco was largely affected by exogenous factors. 4. According to calculation results, the substitution effect between machinery and labor cost was trivial. 5. Rising rate of real price of leaf tobacco by the KTGC's purchasing was higher than that of real production cost. 6. The alternatives of structural improvement in leaf tobacco farming were as follows.; (1) attainment of economy of scale through centralization of production districts (2) improvement of cultivation method to promote productivity (3) stable maintenance of leaf tobacco farmers. (4) transformation of price policy into cost reduction policy

Background : Since 1997, the annual case occurrence of vivax malaria in the Republic of Korea have exceeded 1,000 cases since 1997. The military is thought to be an important source of the current outbreak. We collected various informations about malaria cases (soldiers, veterans and civilians) which occurred in 2000, and analyzed the characteristics of the current outbreak. Methods : Informations about malaria cases of soldiers, veterans and civilians, including name, age, sex, day of onset, region, etc., were collected through the National Institute of Health. Results : Out of total 4,141 cases, 1,288 (31.1%) occurred in the military, 1,273 (30.7%) occurred among the veterans, and 1,580 (38.2%) occurred among civilians. The monthly case occurrence reached its peak in early August. Areas such as Cheolwon, Yeoncheon and Paju showed the highest prevalence. Conclusion : It is considered that the current malaria outbreak has escaped from the exponential growth phase, however, more attention should be paid to prevent further spreading of malaria infection.

Various steps, from preparation of TLC plate to color reaction of spots, of urinary amino acids by means of thin layer chromatography (TLC) were studied. Based upon this procedure studied by Authors, Rf values of 39 ninhydrin positive substances which appeared frequently in urine were measured in accordance with three different kinds of solvent systems, i.e., chloroform-methanol-17 ammonia, n-butanol-glacial acetic acid-water; and phenol-water. In quantitaion of urinary amino acids unique Author's method was introduced as figure 4. Urinary amino acids in Korean, 10 amino acids, in accordance with the order of high frequency, glycine, histidine, alanine, serine, taurine, citrulline, fl-aminoisobutyric acid, arginine, valine, and hydroxyproline, were amount to 82.3% of total amino acids appeared in urine. The remaining 14 urinary amino acids were taken as 17.7%. Comparison with values from Seoul and Kwangju areas obtained on urinary amino acids, former were 7.3 amino acids per individual and range of 4-11 amino acid, and latter were 4.0 and 3-7 amino acids. In sorts of amino acids alanine, taurine, serine, and citrulline were taken as high frequency in Seoul area but were low in Kwangju area. However hydroxyproline and asparagine were appeared as reverse frequency. By studies depending upon morning, noon, and evening groups, variation of urinary amino acids were not showed markedly. Urinary amino acids arginine and valine were appeared scarecely in evening but S-aminoisobutyric acid and tyrosine were frequently.

This paper applies cointegration and error-correction models to test the causal relation between government expenditures and tax revenues in Korea over the period 1953-1995. These econometric techniques have recently gained attention in empirical research not only for simplicity and relevance in analysing time-series data but also for ensuring stationary and providing additional channels through which Granger causality could emerge if two variables are cointegrated. We performed the unit root tests in levels and first differences. The levels of tax revenue and government expenditure variables are non-stationary, but the first differences of that variables are stationary indicating that these variables are in fact integrated of order one, I(1) . We performed Engle Granger cointegration tests by estimating the cointegrating equation in order to obtain the residuals used in the error-correction models. We are interesting to see what causes what, that is, the direction of causality between tax revenues and government expenditures. The empirical results obtained from the error-correction models indicate that causality runs from government expenditures to tax revenues. This is based on the significance of the error-correction coefficient, η. The results imply that higher government expenditures would lead to higher tax revenues.

This study originated from an issue that technological innovation is an important factor in modern agriculture and it should be controlled systematically by government and farms. The objective of this study is to find out the methods of economic evaluation and management system of technological innovation in agriculture. Technological progress in agriculture improves the agricultural production function. For any given amount of inputs, we get more output than we did in the past farming. Modern theories of endogenous growth attempt to explain the rate of technological progress, which the Solow model takes as exogenous. These models try to explain the decisions that determine the creation of knowledge through research and development. The growth of agricultural income per farm is determined by the rate of technological progress. Because technological innovation in modernized agriculture is very important factors increasing the revenue and reducing the production cost. The difference between production functions is due to a difference of technique in how the inputs are used in producing the output. A farmer will not adapt a change in technology unless he expects that the adaption will lead to a reduction in per unit costs at the output at which he expects to operate. Since most innovations involve additional expenditures, total costs are likely to be increased at lower levels of output as a result of technological changes. Nevertheless, in order to increase the agricultural production and the levels of living it is necessary to develope and adapt technological improvements in agriculture. The major problem in agricultural technological innovation is to evaluate the economic value of new technology adapted by farmers in agricultural accounting system and to prepare the technological management system to develope better technology. Farms should reflect the economic value of technological changes through financial analysis in agricultural accounting system. Because an essential activity in financial management of agriculture is the development of a timely technological information system that provides a means for the decision maker as a farm operator to measure, evaluate, control, and improve the financial performance of the farm business. The government should develope the education of the skilled technical hands, R&D investment, the accumulation and risk management of agricultural technological information, and the development and spread of agricultural technology. We can expect the principal role of local agricultural college in technological management system of agriculture by the decentralization of agricultural extension function.

The purpose of this study is to evaluate the advantages and disadvantages of pooling used by agricultural cooperatives and create pooling strategies. Pooling is a way to share risk, expenses, and revenue with other producers by marketing agricultural products together. The advantages of pooling in agricultural marketing can be achieved through the economies of scale and scope. Agricultural marketing cooperatives should try to meet the changing consumer demands for environment-friendly organic products, branded agricultural products, small packaged products and ready-to-eat processed foods. Also, agricultural marketing cooperatives should pay close attention to eliminate the moral hazard problem and to prevent low quality products from being marketed in the process of pooling.
