In deregulated power market, transmission pricing methodology should maintain non-discrimination amongst all participants while ensure that TRANSCOs recover their revenue requirements. The proposed transmission pricing methodology for Korea needs cost allocation ratios, such as allocation ratio of physical transport to network security and that of generators to loads. In this paper, we studied the nodal transmission price determined by the cost allocation factors and its influence on GENCOs and DISTCOs.

Foci of this thesis arc an estimation of willingness to pay and an establishment of green marketing strategics for environment-friendly agricultural products(EFAR). Estimations of willingness to pay for grain, vegetables, fruit and processed food-stuffs arc respectively 20.6%, 20.2%, 19.3% and 17.2% higher than agricultural products produced by conventional farming method. And a green mark6ting mix for EFAP is as follows; Erst, a product strategy focuses on producing safe and high-quality foods by environment-friendly agriculture(EFA) to point to consumer’s health and desire for environmental preservation. Second, in a price strategy, the balance of three factors should be kept, namely the environmental value the true quality as food materials and the price of EFAP. Third, a place strategy is to reduce waste matters, resource and energy uses in marketing chain, and to simplify marketing channels. Also, it is necessary to choose the marketing channel for price discrimination. Fourth, a promotion strategy make use of programs that emphasize the multi-function of EFA.

Global fast fashion brands have been popular and most of them have entered the Korean market. With their success, Korean apparel companies launched domestic fast fashion brands; however, recently they have become fiercely competitive, and consumers are demanding better design and quality and cheaper prices than before. The purpose of this study is to explore consumer purchasing behavior of the global as well as domestic fast fashion brands sold in Korea and to suggest marketing strategies for the brands sold in Korea. The study includes interviewing 61 Korean consumers to ask about their purchasing behavior and experiences. This study found four themes from these in-depth interviews: 1) demand of product glocalization which considers both globalization and localization for better style, quality, and assortment plan, 2) satisfaction with the reasonable price range of fast fashion brands but dissatisfaction with price discrimination among countries, 3) importance of easy, comfortable, and convenient accessibility to fast fashion brands, and 4) preference for good brand reputation related to corporate social responsibility(CSR) and nationality. From these four themes, this study developed the four elements of the marketing mix: product, price, accessibility, and reputation to adapt to a new marketing environment that emphasizes the development of information technology, consumer-centric marketing, and corporate ethics. The findings of this research could contribute useful information to both global and domestic fashion companies as well as consumers.

Modern investment theory has empirically proved that stock returns can be explained by several factors such as market risk, firm size, and book-to-market ratio. Other unknown factors affecting stock returns are also believed to still exist yet to be found. We believe that one of such factors is the operational efficiency of firms in transforming inputs to outputs, considering the fact that operations is a fundamental and primary function of any type of businesses. To support this belief, this study intends to empirically study the relationship between firm efficiency and stock price performance. Firm efficiency is measured using data envelopment analysis (DEA) with inputs and outputs obtained from financial statements. We employ cross-efficiency evaluation to enhance the discrimination power of DEA with a secondary objective function of aggressive formulation. Using the CAPM-based performance regression model, we test the performance of equally weighted portfolios of different sizes selected based upon DEA cross-efficiency scores along with a buy & hold trading strategy. For the empirical test, we collect financial data of domestic firms listed in KOSPI over the period of 2000~2016 from well-known financial databases. As a result, we find that the porfolios with highly efficient firms included outperform the benchmark market portfolio after controlling for the market risk, which indicates that firm efficiency plays a important role in explaining stock returns.

Free-to-play business model, which first commercialized in Korea, now becomes crucial sales drivers in the game industry, but the theoretical background is not well known that most of free-to-play content business models are developed based on the guts and trial-and-errors. In this study, we verified that the price discrimination theory in economics is the backbone of the free-to-play business model, and we also derived the three boundary conditions that should be satisfied in the business model design. We reviewed the three boundary conditions of free-to-play business model using case studies of previous games, and showed how the boundary conditions should work in the actual business. Through case studies, we tried to suggest the theoretical basis of free-to-play business model design, and sales enhancing techniques in free-to-play business.

Credit transactions are used as a means of price discrimination from competitors in order for suppliers to increase customer demand. In particular, in the case of a two-stage supply chain consisting of a supplier, a retailer, and a customer, the deferral of payment for goods allowed by the supplier is a means of reducing the inventory investment cost of the retailer. Retailers have the opportunity to discount the selling price while anticipating an increase in end-customer demand through the reduction of the inventory investment cost. In view of the fact that such trade credit is provided for the purpose of increasing demand as a means of discrimination from competitors, it may be more general that the credit transaction period is allowed flexibly according to the transaction volume. In particular, in the case of deteriorating products, the credit transaction period given according to the order volume is a factor that increases the order volume of the retailer, but product deterioration can be a limiting factor in the increase in the order volume. The deterioration rate actually plays an important role in determining the inventory policy of the retailer. Therefore, in this paper, the effect of such deterioration rate on the inventory policy of retailer is analyzed.

Discrimination of geographic origin of agricultural products is a important issue in Korea because the price difference between Korean domestic and imported cereals is a key among some reasons. NIRS (Near Infrared Reflectance Spectroscopy) has been applied to classify the geographical origin of soybeans. Total 135 samples (Korean domestic 92 and foreign 43) were used to obtain calibration equation through 400~2,500 nm wavelength. The math treatment with 1st derivative and 4 nm gap and the modified partial least squares(MPLS)regression was outstanding for calibration equation. The standard error of calibration and determination coefficient in calibration set(n=115) was 6.65 and 0.98, respectively. And it showed that the extra 20 samples for validation equation were identified their authentication correctly. This study describes that the application of NIRS would be possible for discrimination of geographical origin between Korean domestic and imported soybeans.

Objects: This study was conducted to investigate the current educational environment of herbology and to develop a future-oriented curriculum for oriental medicine. The questionnaire used in this research was drawn up based on the current curriculum referring to the current curriculum of herbology and pharmacognosy. Methods: The survey was carried out presenting the questionnaires to a total 12,754 of the students and doctors of oriental medicine through e-mailing five times; of these, 2,074 replied. Results: 1. Among the respondents, about 97% agreed that it was necessary to revise and complement the current curriculum of herbology. 2. The respondents felt that the assigned lecture time of subject was "sufficient" (19%), "insufficient" (39%) and "average" (39%), respectively, and the level of lecture was "insufficient" (37%) or "average" (43%) respectively. According to priority, it showed that the contents which needed complement in lecture were discrimination of medicinal herbs (24%), practical use of action and indications (23%), and correlation with modern disease (21%). In theoretical lectures, 69% of the respondents agreed on the introduction of natural scientific methods 3. In practice, 51% of the respondents replied that the lecture time for practice was insufficient. The contents which needed to be complemented in practice were as follows: audio-visual materials for discrimination of medicinal herbs (22%), concrete exercise for the processing of medicinal herbs (21%), and attempts for the objective discrimination of medicinal herbs using instruments (microscope, analytical instrument, residual pesticide, heavy metal, genetic analysis) (16%). 70% replied that the discrimination of medicinal herbs of high price and rarity was "none or insufficient". 4. 56% replied that it was necessary to introduce and practice physicochemical analysis, and they showed higher requests according to the increase of their educational level. However, 86% replied that they had never experienced concrete attempts for objective discrimination of medicinal herbs, which seemed to indicate that, excepting some schools, practice exercise was rarely performed. Conclusions: According to results, it seems that an urgent review on the current course of herbology and a workshop on the process of experimental practice for professors is needed.
