Causing by economic stagnation and financial management difficulty of the domestic small and medium business company, the actual condition which enlarges the plan of politic funds increased from the government. The government authority as the SBC (small and medium business promotion corporation) evaluates the domestic small and medium business company, and directly executes a governmental politic funds. Financial analysis is a important factor of enterprise evaluation among various valuation bases. However because of applying to the whole domestic manufacturing industry on financial evaluation, Current financial evaluation index effectively cannot reflect the feature of a regional industry. A whole manufacturing industry index considers a standard for the comparison evaluation of domestic manufacturing industry and compares with the other industries and the world-wide nation industry change, But, there is a difference from indexes of corresponding industry in specific regions. This paper proposes a model of evaluation index for the efficient execution of politic funds. We considers three manufacturing industries for proposed model which are shipbuilding, machine tool and airline industries in Gyeongsangnam-do region.

Korea's social health insurance system was introduced in 1977, which has made a universal coverage possibly by July 1989. Korean government had pursued a single objective for the last decade to put the whole population under the coverage of medical security, and the objective was achieved within 12 years. The rapid accomplishment is primarily due to such factors as limited benefits, high copayment rate, low contributions as well as rapid economic growth. There are several sources of pressure for the implementation of social health insurance such as health professional group, labor unions, politicians, international organizations etc.. However it is important to look at the feasibility of social health insurance. Among other things, it is necessary to identify the administrative infrastructure of insurance system and to assess income for source of fund. As many developed countries, Korea began to apply health insurance to the employees of the large firms, and the expansion based on employment status. Thus the several funds system was inevitable according to the gradual expansion strategy. However many persons had criticized several funds system in respect with equity and efficiency aspects. In the short history of the Korean health insurance, whether one fund or sever or funds had been the most controversial issue. In Febrary 1999, the National Assembly passed the act of one fund system. From July 2000 separate funds will be unifed under new health insurance scheme. In this study we will analyze the policy making process on implementation, expansion and integration of health insurance system of Korea. And also analyse problems related to policy making.

Purpose: The article looks at the member' rights and trustees duties and determines where should the emphasis be as it often happens that these two aspects often clash. Research Design, Data and Methodology: It is determined in this article whether the trustees owe fiduciary duties to both the fund and members and further determines whether the trustees should advance the interests of the members. Results: The article further looks at the governance of the retirement funds and argues that the proper governance of these funds protects the interest of the members. The duty to disclosure of information to members is of paramount importance to ensure that members are able to make well informed decisions. Conclusion: The article considers the issues of disclosure of information from other countries, United Kingdom, United States and Malawi. It is argued in this article that trustees must be persons who are trustworthy and have the best interest of the members at heart and must therefore familiarize themselves with the laws that regulate their duties.

This paper suggests that, in contrast to main argument of Efficient Market Hypothesis, hedge funds's financial speculation activity in the commodity markets are tending to generate a malfunction of making future price diverge from fundamental price. For this reason, we insist that stricter regulation on commodity derivative markets, including position limitation, is needed. Using some statistic analysis tools, we show that derivative transaction volume is getting so larger that financial speculation by hedge funds dominates price movement in commodity market and eventually slackens the speed of price's return to the fundamental price.

Combining the strength of both Mixed Data Sampling (MIDAS) Regression and realized variance measures, this paper seeks to investigate two objectives: (1) evaluate the post-sample performance of the proposed weekly Realized Variance-MIDAS (RVar-MIDAS) in one-week ahead volatility forecasting against the established Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model and the less explored but robust STES (Smooth Transition Exponential Smoothing) methods. (2) comparing forecast error performance between realized variance and squared residuals measures as a proxy for actual volatility. Data of seven private equity mutual fund indices (generated from 57 individual funds) from two different time periods (with and without financial crisis) are applied to 21 models. Robustness of the post-sample volatility forecasting of all models is validated by the Model Confidence Set (MCS) Procedures and revealed: (1) The weekly RVar-MIDAS model emerged as the best model, outperformed the robust DAILY-STES methods, and the weekly DAILY-GARCH models, particularly during a volatile period. (2) models with realized variance measured in estimation and as a proxy for actual volatility outperformed those using squared residual. This study contributes an empirical approach to one-week ahead volatility forecasting of mutual funds return, which is less explored in past literature on financial volatility forecasting compared to stocks volatility.

Purpose - This study introduces a methodology for finding the optimal tracking error of active stock funds. Tracking error is commonly used in risk budgeting techniques as a concept of cost for alpha creation. Design/methodology/approach - This study uses a post-optimal smart beta portfolio that maximizes alpha under the given tracking error constraint. Findings - As a result of the analysis, the smart beta strategy that maximized alpha under the constraint of 0.15% daily tracking error shows the highest IR. This means the maximum theoretically achievable efficiency. In this regard, a fixed-effect panel regression analysis is conducted to evaluate the active efficiency of domestic stock funds. In addition to control variables based on previous studies, the effect of tracking error on alpha is analyzed. The alpha used in this model is calculated using the smart beta portfolio according to the size of the constraint of the tracking error as a benchmark. Contrary to theoretical estimates, in Korea, the alpha performance is maximized under a daily tracking error of 0.1%. This indicates that the active efficiency of domestic equity funds is lower than the theoretical maximum. Research implications or Originality - Based on this study, it is expected that it can be used for active risk management of pension funds and performance evaluation of active strategies.

After Liberation of Korea, Korean fisheries economy fell into an exhausted conditions because of the damage of Japanese colonization policy and the Korean War, and fisheries organizations of those days established for the improvement of fishermen's welfare could not carry out their primary purposes and functions. Under such circumstances, Fisheries Cooperatives starting on April 1st in 1961 played a great role in settling the socio-economic confusion of those days. Fisheries financing was also more systematic and substantial after establishment of Fisheries Cooperatives. In fact fisheries industry was faced with much more riskiness than any other industry on account of its speciality and such a riskiness induced general financial institutions to be reluctant to lend money to the fishermen. In order to overcome such a capital rationing, it was necessary to establish the reciprocal financing system based on the principle of mutual protection of economic weakers. Credit business in Fisheries Cooperatives beginning in 1963 was mainly dependent on governmental fund as fund sources. But the size of fund was too small to satisfy fishermen's fund demand, therefore Fisheries Cooperatives carried out the movement of raising its own fund. As a result of the movement the ratio of its own fund to total funds amounted to 47.7% in 1980, but external funds still take a greater part of all funds. To settle the weakness of the ratio of its own fund and chronic deficiency of fund, a conclusion can be drawn as follows : 1. The enlargement of Fisheries Cooperatives' raising ability of funds. .The expansion of urban branch to absorb idle funds in urban area. .The diversification of financing service to compete with genetral financial institutions. 2. The enlargement of governmental fund and preferential treatment of fishermen's savings. 3. Vitalization of mutual finance and fixation of Fisheries Cooperatives' two-phase organization. 4. The re-enforcement of supervisory financing and post management system.

The government authorities holds a policy that they should impose a tax on the research funds which are judged to be profits from commercial research service among others provided for academic research and development fields. This study reveals the present condition of the research funds and suggests a counterproposal and legal complement. In concrete terms, the present condition of research funds in universities, the provisions concerned with them, opinions of Korean National Tax Service on the profits from them, problems following the provisions and policies, and the foreign taxation cases upon them are investigated. As a result, the counteract policy that research funds should be laid tax on with caution to clarify the criterion for judging whether a research service is commercial and noncommercial, and to supplement unprepared part of the legal propositions.

Purpose - This paper aims to examine the determinants of SWFs' investment in Asian countries and to identify consistent investment patterns of SWFs in specific target firms from Asia, particularly China and South Korea. Design/methodology - This study extends the Tobin's Q model to examine the relationship between SWF investments in target firms and their returns with other firm-level control variables. We collect consistent data on SWF investments and the matched firm-level data on target firms, which of observation is 1,512 firms (333 in South Korea and 1,179 in China) targeted by 20 SWF sources during 1997-2017. The panel random effect model is used to estimate the extended Tobin's Q model. The robustness of the estimations is tested by the simultaneous equation models and the panel GEE model. Findings - The evidence shows that sovereign wealth funds are more inclined to invest in the financial sector with a monopoly position and in large firms with higher growth opportunity and superior cash asset ratios in China. In contrast to their investments in China, sovereign wealth funds in South Korea prefer to invest in strategic sectors, such as energy and information technology, and in large firms with high performance and low leverage. Sovereign wealth funds' investments tend to significantly improve the target firm's performance measured by sales growth and returns in both Korea and China. Originality/value - The existing literature focuses on examining the determination of SWFs investment in the developed countries, such as Europe and the United States. Our paper contributes to the literature in three ways; first, we analyzes case studies of SWF investments in Asian markets, which are less developed and riskier. Second, we examine whether the determination of SWF investment in Asian target firms depends on the different time periods, on types of sources of SWFs, and on acquiring countries. Third, our research uses vast sample data on target firms in longer time periods (1997-2017) than other previous studies on the SWFs for Asian markets.

In this paper we consider the CSP requirements determination problem of new equipment system. The CSP we deal with in the paper are restricted to the demand-based spare parts. For the newly procured equipment systems, mathematical analyses are made for the system which is constructed with the repairable items to derive the associated CSP requirement determination model in mathematical expression, respectively. Based on these analyses, a mathematical model is derived for making an optimal CSP requirement determination subject to the constraint of satisfying any given funds limitation. We assume that the failure of a part follows a Poisson process. Firstly, the operational availability concept in CSP is defined and the relation between the general system availability and the operational availability is established. Secondly, the problem is formulated as the operational availability maximization problem that should satisfy the funds limitation, and then, using the generalized Lagrange multipliers method, the optimal solution procedure is derived.
