Electricity Market in Korea can't provide locational price signal through energy price because energy market is CBP(Cost Based Pool) using uniform price. Generators don't want to locate in a densely populated load area(like the metropolitan area). Because they are paid more fixed cost in metropolitan area. This situation has loss and congestion occurred in power system. However energy market without price signal can't lead generator to the metropolitan. So, market participants should be provided price signal through the transmission price instead of energy price. This paper proposes transmission pricing method considering reliability cost in order to offer price signal. Also, it proposes the method to allocate the transmission cost to each transmission line user through a fair and a reasonable manner. The transmission price is decided by the reliability value of each line. If a transmission line of high reliability value is broke, users using that line will get a loss and a discomfort. So, it is fair that users using a transmission line of high reliability value pay more than the other users. Also, it is reasonable that a transmission line owner get paid more form users using that line.

This study attempts to investigate the influence of the parental reality show viewing on both the marriage expectation and family value. More specifically, this study investigate the effect of the parental reality show() viewing on marriage expectation(romance and partner expectation), fair parental role model value, and parental nursing efficacy. Indeed, the mediation effects of wishful identification were examined. For this purpose, this study surveyed 407 college students from three different areas. The results showed that the viewing had significant influence on both romance and partner expectation directly as well as indirectly through wishful identification. For the family value, the viewing did not directly influenced on the fair parental role model value, however, it had indirect effects through wishful identification. Meanwhile, viewing had only the direct effect on the parental nursing efficacy.

This study aims to verify the effects of unrealized gain or loss, that is the fair value evaluation item of insurance company's assets and liabilities, to capital markets focusing on fair value evaluation of insurance company's liabilities, which is the core of IFRS 17 that will be implemented in 2021. For this purpose we carried out regression analysis to verify the effects of changed other comprehensive income(OCI) and accumulated OCI, published in quarterly financial statements of listed insurance companies, on stock price utilizing Ohlson(1995)'s extended test model. The results of the empirical analysis are as follows. First, changed OCI showed a significant negative(-) effects on stock price. Second, accumulated OCI revealed a significant positive(+) effects on stock price. Furthermore, extended test model classifying changed OCI and accumulated OCI in a basic model represented the highest $R^2$ number and public announcement policy of OCI, a kind of unrealized gain or loss item, implied that it could give positive impact on accounting information. But still the direction that unrealized gain or loss affects on firm value must be carefully reviewed and considered in the future via more detailed study by the user of information. Therefore this study is meaningful in that it can predict usefulness of information on insurance company's fair value evaluation via empirical test accompanied by introduction of newly established IFRS 17 and it also can suggest direction of information production suitable for capital market.

This paper presents a new DR(Dead Reckoning) algorithm in client-server-based networked virtual environment using network delay estimation. In the algorithm, a new update packet is sent to server (or client) whenever the difference of current real value and tracking value after network delay is larger than threshold. To confirm the proposed algorithm, a test network game was implemented. Through iterative field tests, we knew that this algorithm provides fair service and stability.

The purpose of this research is to reveal the problems of the Western based development discourse, and to derive the future direction of postdevelopment as sustainable development. This study attempted to reveal the historical process of formation and change on development discourse. Development generally regarded as the overcome of underdevelopment, inducing the marginalization of the South as a place to follow the development model of the North. State based development discourse (Keynesian development discourse) focused on the growth by industrialization, and the supreme aim of the South was to overcome the underdevelopment. Neoliberalism development discourse emphasized on the market principle based on free competition which was recognized as the best way to provide development. However, neoliberalism discourse has been criticized for the concentration of power and inequality of class, causing on the consideration of postdevelopment because of its emphasis on growth rather than distribution and life value. This research revealed the ways of postdevelopment with fair trade and ethical consumption. However, fair trade and ethical consumption discourses clearly show somewhat limitation subsuming into neoliberal development discourse. In this respect, future ways for postdevelopment have to consider the overcoming of powers based on market and capital, and to orient into the value of redistribution in development process.

The purpose of this paper is to suggest a rational cost allocation method that is efficient and fair. Cost allocation by taking cooperative game theory shows fair allocation considering marginal cost by ship type. Current berth occupancy charging method can not recover quay construction costs. Because it levies charges according to berthing time and tonnage of ships without considering the recovery of quay construction costs. And there are also cross subsidies among ships. This paper suggests the cost allocation method of cooperative game theory as a fair and efficient method.

In a rapidly changing Korean society, the role of home economics in ideological education and practical professionalism is faced to be reset. In this article the author reviews home economics and career opportunities. the following issues were discussed in detail : 1. Home Economics and Occupation ; a) As professionals in the field of home economics, job applicants must carry their message in person to potential employers. Employers must be taught that persons with home economics degrees have the capabilities and qualifications to fill a variety of positions. b) In may of 1977, Vocational Education Coalition was established by American Home economics association (AHEA), American Vocational Association, and Home Economics Education association This coalition defined the vocational education as occupation of homemaking and paid employment in home economics occupations for women and men. 2. Home Economics in business: Twelve percent of the total membership of the AHEA is affiliated with the home economics in business section. A professional management consultant, Dr. strain's viewpoint and corning Glass Work's case about business value in the home economics were summarized; a) Why a business employs a home economist. b) Why a business does not employ a home economist. c) Enhancing the home economist's value. d) Home economist's roles in corning Glass works. 3. Creating a Career: a) Mrs. Maineri's story. b) Family financial counselors. c) Home economist and displaced homemaker. d) Job opportunities in international services. Since the role of home economics in Korea has had little perception in professionalism, the following issues require immediate and serious attention to enhance career opportunities for home economists: Employers and government's recognition of home economist's value, Home economist's attitude to enhance their value, Fair employment and sex discrimination, Curricula adjustment, and Support from women's organization for employment opportunities, fair treatment, top jobs, etc.

Derivative-linked securities (DLS) is a type of derivatives that offer an agreed return when the underlying asset price moves within a specified range by the maturity date. The underlying assets of DLS are diverse such as interest rates, exchange rates, crude oil, or gold. A German 10-year bond rate-linked DLS and a USD-GBP CMS rate-linked DLS have recently become a social issue in Korea due to a huge loss to investors. In this regard, this paper accounts for the payoff structure of these products and evaluates their prices and fair coupon rates as well as risk measures such as Value-at-Risk (VaR) and Tail-Value-at-Risk (TVaR). We would like to examine how risky these products were and whether or not their coupon rates were appropriate. We use Hull-White Model as the stochastic model for the underlying assets and Monte Carlo (MC) methods to obtain numerical results. The no-arbitrage prices of the German 10-year bond rate-linked DLS and the USD-GBP CMS rate-linked DLS at the center of the social issue turned out to be 0.9662% and 0.9355% of the original investment, respectively. Considering that Korea government bond rate for 2018 is about 2%, these values are quite low. The fair coupon rates that make the prices of DLS equal to the original investment are computed as 4.76% for the German 10-year bond rate-linked DLS and 7% for the USD-GBP CMS rate-linked DLS. Their actual coupon rates were 1.4% and 3.5%. The 95% VaR and TVaR of the loss for German 10-year bond rate-linked DLS are 37.30% and 64.45%, and those of the loss for USD-GBP CMS rate-linked DLS are 73.98% and 87.43% of the initial investment. Summing up the numerical results obtained, we could see that the DLS products of our interest were indeed quite unfavorable to individual investors.

Anyang-cheon(stream) runs through southern metropolitan area of Seoul to Han-river in Korea. Due to fast growth of Seoul, the water quality and quantity problems in Anyang-cheon have occurred. To cope with the problems, the Integrated Watershed Management program for Anyang-cheon was adopted and a KRW 26.1 billion (USD 21.8 million) pilot project (construction of 4 facilities such as reservoir) is suggested for 4 sub-watersheds of Anyang-cheon, which cost will be shared by the 12 local governments (LG). Three cost division schemes are compared. By Scheme 1, if the cost is borne by the LG in a watershed where the facilities are constructed (no cost division scheme), the LG in I is to bear 0.58% of the total construction cost, LG in watershed II 29.54%, LG in IV 0%, LG in V 69.88%. In particular, LG in IV in this scheme bears no cost because no facility is constructed, even though watershed IV is the major beneficiary of the facility construction. Scheme 2 is to share the cost by length of streams in each sub-watershed and the suggested cost share for each sub-watershed is 13.76% by I, 7.34% by II, 45.87% by IV, and 33.03% by V. However, this cost division scheme is fair only under the false assumption that the bargaining powers of group of LGs are identical. To suggest a better and fair division rule, Shapley Value, a cooperative game solution, is used to suggest Scheme 3. In Scheme 3, Shapley Value measures the summation of average marginal contribution of each player in all possible coalitions as cost division scheme and is known to provide a fair division considering bargaining power. In the context of Anyang-cheon, LGs in upper stream have superior bargaining position. The result suggests the cost division is fair under Scheme 3, when the cost shares are 0.29% by I, 14.77% by II, 50% by IV, and 34.94% by V, respectively.
