In Korea, there is great lack in jet lease agreements compared to many other countries. Due to such scarcity in numbers of jet lease agreements, problems have never truly surfaced and legal foundation dealing with such issues have not yet been formulated. However, as the globalization is making the world smaller and smaller, the demand for jets will grow. As the Korean aviation industry is expanding tremendously, although very preliminary at this time, the interest and actual execution on private jet lease agreements will grow. The prediction of increase in the private jet ownership is causing the lease industry to be nervous and may require particular preparatory foundation works. Particularly, legal analysis and detailed review maybe necessary to set a precedent with will serve as the grounded rule in the future. It is notable that Vietnam, a country which is believed have a less developed aviation industry than Korea, had already established a specialized jet leasing company, VALC in 2007. Also, when leasing an airplane from a foreign financial institution, it is possible to obtain a government issued guarantee. Therefore, it is urgent for Korea to prepare the legal foundation for the future demands in aviation leasing, as well as private jet leases which in turn would promote national wealth and further develop the financial industry.

Purpose - Along with the rise of foreign investments in the Korean stock market, there has been a variety of studies on their influence. The conflicting findings on the question of information asymmetry of foreign investors among existing literatures appear to be a result of mixture of research method problems, what information is defined as being comparable, individual business levels, or the entire stock market. This paper empirically investigates what factors contribute to foreign investments in firms in the Korean stock market. Research design, data, and Methodology - Samples are constructed by manufacturing firms listed on the stock market of Korea as well as those who settle accounts in December from 2001 to 2018. Financial institutions are excluded from the sample as their accounting procedures, governance and regulations differ. This study adopted the panel regression model to assess the sample construction including yearly and cross-sectional data. Result - This paper find that firms' R&D, dividends, size give significant positive impact to foreign investment, whereas debt gives significant negative impact to foreign investment. This relationship does not change when the samples are divided before and after the 2008 global financial crisis. Conclusion - This results support the literatures that foreign investors favor firms lowering their information asymmetry.

Purpose - The ultimate goal of a franchise system comes from its win-win strategy. Agency theory uses goal incongruity to examine complex contracting problems between buyers and suppliers. Goal incongruity within a contractual relationship can be defined as the agent's desire not to cooperate. It is the degree to which the contractual terms do not satisfy the agent's goals. The greater the goal incongruity between the agent and the contract, the more likely it is that the agent will meet the terms of the contract. Thus, goal incongruity between buyers and suppliers has close relationships with both behavioral and financial performance. This study tries to examine these relationships in the franchise context using a model including related variables, such as regulatory foci, financial performance, and opportunism, to explain the reasons that not all franchisees perform their best. In particular, the study examines the effects of goal incongruity on regulatory focus, and the effects of regulatory focus on performance and opportunism. In short, the objective is to determine goal incongruity's effect on regulatory foci, and the effect of regulatory focus on performance and opportunism. Research design, data, and methodology - This study used data collected from the franchisee managers of 104 franchisors in South Korea. The franchisors include more than 10 franchisees, the majority of whom have been in business for more than five years. The study also surveyed 104 franchisees, matched with their franchisors for the sake of a dyadic approach. The study used regression analysis to test the hypotheses. Results - H1 and H2 predicted that goal incongruity would decrease promotion focus and increase prevention focus. Supporting H1, the result indicates goal incongruity had a positive effect on promotion focus. However, H2 was not supported. Goal incongruity had no significant effect on prevention focus (β = -.375, t = -4.331 and β = -.145, t = -1.950, respectively). H3 and H4 predicted that promotion focus would increase financial performance and decrease opportunism. Supporting these hypotheses, the results indicate that promotion focus had a positive effect on financial performance and a negative effect on opportunism (β = .771, t = 7.899 and β = -.765, t = -6.778, respectively). H5 and H6 predicted that prevention focus would decrease financial performance and increase opportunism. However, the results do not support these hypotheses. The results indicate that prevention focus had no effects on opportunism or financial performance (β = -.130, t = -1.070 and β = .090, t = .641, respectively). Overall, the evidence generally supported the hypotheses. Conclusion - Goal incongruity between a franchisor and a franchisee increases the franchisee's financial performance and opportunism, and the relationship is mediated by promotion focus. Interestingly, however, prevention focus has no mediating effect between goal incongruity and performance. Even though no significant relation exists between goal incongruity and prevention focus, the results have two implications. First, decreasing goal incongruity can improve financial performance and suppress franchisee opportunism. Second, the relationship between goal incongruity and performance affects promotion-focused franchisees.

Recently, energy Problem has become more important thing than that of past years. Therefore, researchers in many countries are trying to find the solution for removing energy Problem. One of all is the power generation with using the photovoltaic system. Because this system has some advantage, like purity and infinity. However, there are some problems to generate electrical power with using photovoltaic system. That problems, taking up a very big space and taking financial worries, come into existence. So it is inevitable to make the visual implement equipment for doing repetition experiment and solving this problems. In this paper, Boost converter are analyzed and simulated to make high power PV virtual implement system as input source instead of using transformer.

The number of organic farms are increasing in European countries during last 10 years. Most European governments are giving subsidies for organic farmers as well as converting organic farms from conventional farming method. The price level of most organic products are higher than price level of conventional products in general. However, there are certainly some market demand problems in organic products in some countries. Organic farms will be increased in 2005 and 2010 for 10∼20% of the total agricultural area in some European countries. Government subsidy payment is also increasing. Therefore, many farmers are going to change into organic farming method from conventional farming. However, there will be certainly some market demand problems in future because of national economic growth problems. At the same time, the quality of soil can be improved and status of health of urban consumers should be improved by consuming organic products.

The major problems of chemical fertilizer supply and consumption involved in price policies since the end of World War II in Korea and their solutions were extensively discussed. The period was divided into three sub-periods: 1946-1960, 1961-1967 and 1968 to present. Since 1968 when the operations of three large-scaled fertilizer plants: Yongnam Chemical Co., Chinhae Chemical Co. and Hankuk Fertilizer Co. were begun in full scale, the domestic supply of nitrogen and phosphate fertilizers were almost enough for the domestic demand. However, since 1976, when Namhae Chemical Co. was added to the production capacity, the fertilizer industry has been faced with the overproduction problem of nitrogen, and the high production cost due to high petroleum price, which gave financial difficulties. Several policy directions and alternative measures for solving the current problems were also suggested in this presentation.

We examine the self-control problems of U.S households and their effects on households' retirement preparedness based on the Behavioral Life-Cycle Hypothesis. Using the 2010 Survey of Consumer Finances dataset, the level of retirement adequacy was estimated with income replacement ratio (IRR), and only 42% of households were adequately prepared for retirement. Results from logistic regression analysis indicated that households with loan payment and saving self-control problems were less likely to be prepared adequately for retirement compared to those without such problems. Age, education, race/ethnicity, marital status, employment status, retirement plans, expected retirement age and risk tolerance were significantly related to retirement preparedness. This study provides financial educator and researchers with suggestions on how to help household make a better retirement plan.

Building classifiers for financial real-world classification problems is often plagued by severely overlapping and highly skewed class distribution. New performance measures such as receiver operating characteristic (ROC) curve and area under ROC curve (AUC) have been recently introduced in evaluating and building classifiers for those kind of problems. They are, however, in-effective to evaluation of classifier's discrimination performance in a particular class of the classification problems that interests lie in only a local operating range of the classifier, In this paper, a new method is proposed that enables us to directly improve classifier's discrimination performance at a desired local operating range by defining and optimizing a partial area under ROC curve or domain-specific curve, which is difficult to achieve with conventional classification accuracy based learning methods. The effectiveness of the proposed approach is demonstrated in terms of fraud detection capability in a real-world fraud detection problem compared with the MSE-based approach.

Selecting an appropriate railway system in urban railway project is an important step for an efficient public transport policy. This paper attempts to solve the railway system selection problems in the (pre)feasibility study or preliminary research of urban railway project, by the rough transportation demand forecasting and financial analysis. There are two stages in this paper: in stage one, we review the worthwhile and various criteria which presented in precedent studies; whereas in stage two, an structured selection criteria is proposed for determining the appropriate railway system in urban railway project. The utilization of the proposed criteria is demonstrated with the case of a newtown in the metropolitan area. The results show that proposed criteria can be used to make the rational decision for governmental financial condition and social benefit.
