Most of Korean broiler farms are constructed with vinyl houses. Such types of broiler farms might be cheaper in terms of cost, but poor in terms of environment condition. According to enlargement of broiler farm size, high value production systems or automatic facilities are introduced in this field. However, investment may not always guarantee the profit of the management. Therefore, it is necessary to undertake the investment analysis before decision making for the investment. Under the assumption that 870 Pyoung(≒$3.3㎡) of a broiler farm within 1,740 Pyoung(≒3.3㎡) of land is built with the producing capacity of 50,000 heads of chicken in a time. The total investment is calculated to be 600 million won(1,000 won≒$1.1), and out of them 58.1% is provided by the owner, 31.6% from the government loan, 5.8% from government subsidy, and 5.3% from other agencies or banks. The expected profit of the broiler farm is 64.6 million won(1,000 won≒$1.1) per year. The IRR calculated is 0.0808 which means that the rate to profit of this project would be 8.1%. This also means that for this investment the interest rate of the capital provided should be less than 8.1% per year. Considering that the current opportunity cost of the own capital is 8.5% this project is not so attractive for those who is going to build broiler farms mainly with their own capital. In other words this project would not be profitable, unless the average interest rate of the loans provided for this project is less than 8.1% per year.

이 연구는 패널자료를 이용해 지역별 출산율 변동의 차이를 살펴보고, 지역노동시장과 지역부동산시장 요인이 지역별로 출산율 변동에 어떻게 상이한 영향을 미치는지 살펴보는 것을 목적으로 한다. 기존 연구들은 청년층의 고용과 주거 문제가 출산율 하락의 구조적 요인임을 강조해 왔다. 하지만 청년문제는 지역별로 상이하며, 이런 점에서 고용과 주거 문제가 출산 행위에 미치는 영향도 지역별로 상이할 수 있다. 이 글은 2012년부터 2018년까지 시군구 단위의 패널자료를 구축해서 지역노동시장과 지역부동산시장 상황이 출산율에 미치는 영향을 고정효과모형과 동적패널 모형을 이용해 비교·분석하였다. 분석결과 노동시장 변수와 부동산 시장 변수는 수도권과 비수도권 지역에서 상이한 효과를 갖는 것으로 나타났다. 서울과 경기·인천 등 수도권 지역에서는 높은 집값이 출산에 모두 부정적 영향을 미치는 반면, 비수도권 지역에서는 높은 집값이 오히려 출산에 긍정적 영향을 미치는 것으로 나타났다. 수도권 지역의 부동산의 비용효과가 우세하고, 비수도권 지역은 자산효과가 우세하다고 해석할 수 있다. 노동시장 변수가 미치는 영향력은 통계적으로 유의미하지 않았다.

Since 1989, Advanced drinking water treatment processes began to build in Korea, especially the water treatment plants around the Nak-dong river stream due to sequential pollutant accidents. Moreover, Advanced drinking water treatment processes, ozone and GAC, are again to be built in water treatment plants around Han-river stream to control taste and odor, micro pollutants. However, there are still a lot of discussion to decide the processes to apply for advanced treatment. Thus there are still need to understand clearly on the cost evaluation of each advanced treatment processes. The cost evaluation was accomplished based on the data of six water treatment plants which are currently being either operating or constructing. Exceptionally, PAC(Powdered Activated Carbon) process was evaluated with cost estimation from construction company. The capital cost per unit volume of ozone process was significantly decreased as the treatment capacity increased. The capital cost was in the order of GAC, ozone and GAC. The operation cost decreased in the order of PAC, GAC and ozone. The total cost considering present value shows that ozone process covers 84% of ozone and GAC process for $30,000m^3/d$ capacity while it covers less than 35% for over 140 thousands $m^3/d$ capacity. Comparing GAC only, and ozone/GAC process, ozone/GAC process is more cost effective for high capacity water treatment plant.

This study investigates the facilitating factors of FDI (foreign direct investment) inflows in 15 developing countries of three continents (Asia, Latin America, and Africa) using fixed-effect panel regression analysis with 30-year macro socio-economic data. The facilitating factors of FDI inflows in each continent differed. In Asia, labor compensation, GDP, consumer expenditure, human capital, and export facilitated FDI inflows in decreasing order, as did export, total factor productivity, GDP, and human capital in Latin America, and investment expenditure, human capital, government expenditure, and export in Africa. Most importantly, the character of cost saving efficiency-seeking investment was very strong in Asia. Also, third-party export-oriented investment and economic growth-oriented investment were shown in Latin America and Africa, respectively.

Farm mechanization has been rapidly progressed in rice farming since the 1980's, in Korea. The mechanization has been achieved up to 95-97% in the year of 1995, except irrigation and drying process. However, rice production cost remains much more expensive than the cost of other rice farming countries. Since labor cost shares a major portion of the production costs, it is essential to save labor cost with automation and more sophisticated mechanization. However, it requires great capital investment which causes farm management worse. Therefore, the computer program was developed which can select machines to minimize the management and maintenance cost by analyzing available working days in different areas, machinery to purchase, farming size, total farming size in a village, number of machines and custom fee.

Purpose - The objective of this study is to investigate what motivates global FDI inflows in the different economic development level and to clarify the FDI motivation type in the level of qualitative economic growth. Design/methodology/approach - Major macroscopic social·economic factors induced FDI inflows were analyzed using fixed-effect panel regression with 30-year panel data of 28 countries from 1985 to 2014. For analysis in the stage of economic growth, two category of developed and developing countries was used. And to analyze FDI motivation type in the level of qualitative economic growth, 4 shares of GDP; consumption·government·investment expenditure and export, was used as explanatory variable. Findings - In developed country, TFP(total factor productivity) and GDP have a great influence on FDI inflows, and consumption and labor compensation have a slight effect. This result indicates that the market seeking-driven, horizontal type investment is shown along with efficiency seeking investment. In developing country, human capital and TFP is shown to have greater impact on FDI inflows and labor compensation, exports, investment and government expenditures also have impacts. Thus it has confirmed that not only efficiency-seeking vertical investment for using low cost well educated laborer, but also government-driven economic growth and export policies could affect the FDI inflows. Research implications or Originality - The FDI investment decision making of multinational companies is decided by their own purpose. But, in the concept of as follows; 1) FDI is a long-term capital flowing for maximization of economic utility with limited global resource, 2) Thus FDI could be affected by macro socio·economic factors of host country. 3) Also such macro factors is different by each economic growth qualitative level. Therefore macro socio·economic factors of each country could be affected by the qualitative level of their own economic growth. To attract FDI inflows, it is desirable to implement differentiated incentive policies in the qualitative level of economic growth. Furthermore in developing countries it is recommended to implement government driven economic growth policies as follows; fostering well educated human resources, improving technology productivity in the relative lower cost labor market compared to developed countries and boosting international export volume.

국내 자동차부품기업의 효율성 분석에 대한 연구들은 투입자산 대비 매출액등 성과창출의 크기를 산출변수로 하는 연구들이 대다수였다. 그러나 기업의 성과지표인 매출액, 영업이익, 당기순이익 등은 비용구조와 직접적인 연관이 있고, 이러한 비용구조는 기업의 자산구조와 자본구조의 변동에 의해 영향을 받는다. 결국, 적절한 투자를 통해 효율적 경영성과를 창출하는 것은 효율적 자본조달이 동시에 이루어 져야 할 것이다. 본 연구는 이러한 점에 착안하여 현대기아자동차에 차제부품을 납품하는 1차 협력업체 33개를 대상으로 기업이 창출한 매출액등 성과지표 대비 조달자본의 효율성을 측정하고자 한다. 효율성을 평가하는 방법 중 비모수적 방법으로 가장 널리 사용되고 있는 것이 선형계획법에 기반한 DEA모형이다, 그러나, 효율적 프론티어에 기반한 DEA모형은 효율성에 하향적 영향을 주는 변수를 그대로 사용할 수 없는 한계를 지니고 있다. 이로 인해 자본조달과 관련된 차입금, 총부채등에 대한 변수를 직접적으로 고려하기에는 부적합하다. 본 연구에서는 한계점을 개선하기 위해 Worst Practice DEA를 이용하여 자본조달 측면의 효율성을 측정하였으며 국내 자동차 부품기업의 자본조달 측면의 효율성 개선 방향을 제시하였다.
