The purpose of our research is to identify the critical variables and to develop a new methodology for market segmentation of online game market. Our research tested the model with Korean online game users because Korean online game industry is the frontier of global online game industries. Conclusively, the critical variables are the suitability of feedback, the reality of design, the precision of information and the involvement of virtual community. The analysis of segmentation shows that the primary target audiences are positively influenced by the reality of design and the involvement of virtual community. To attract the primary target audiences, online game companies should develop strategies depending on the effectiveness of the variables and the demographic and behavioral characteristics of target audiences.

Bread making is based on several simple unit operations, basically kneading, fermentation and baking; however, it is still a quite complex process and bread quality can be strongly affected by minor details. The market of bread production is roughly shared at 50-50 between the industry market and the artisanal market, even though the frontier between these two players is not very easy. Different strategies have been developped by the industry to extend the shelf life of bread or to interrupt the bread making process. Freezing for example has been used form the 50s to extend the shelf life of bakery products. It was first applied to fully baked products and then to frozen dough which appeared as an interesting strategy to interrupt the bread making protocol. This paper presents a review on key issues of the frozen dough technology.

한국 기업은 그동안 미국 일본 EU 등 선진국 기업들을 벤치마킹하면서 양적 성장 전략을 추구하여 세계시장에서 놀랄만한 성공을 거두었으나, 최근 세계경제가 저성장의 뉴 노멀(New Noraml)시대로 접어든 데다 중국 인도 등 신흥국들의 경쟁압력도 더욱 거세짐에 따라 세계시장에서 입지가 좁아지고 있다. 따라서 본 연구에서는 한국 기업이 앞으로 세계시장에서 후발 추격자를 따돌리고 경쟁우위를 확보, 유지하기 위해서 어떤 전략적 선택을 해야 할지 분석하였다. 또한 한국 미국 중국이 세계시장에서 치열한 경쟁을 벌이고 있는 스마트폰 산업을 대상으로 Porter의 다이아몬드 모델(Diamond Model)과 생산성 곡선(Productivity Frontier)이라는 분석의 틀을 사용하여, 선도자인 애플, 추격자인 삼성전자, 새로운 후발 추격자인 중국 기업의 경쟁력을 비교 분석하여 향후 스마트폰을 비롯한 주력 산업별 기업들이 세계시장에서 취해야 하는 전략적 포지셔닝을 제시하였다.

HANSSEM is a furniture company that leads the market of residential space in Korea. The goal of this case study is to focus on how HANSSEM copes with IKEA, the world's largest furniture retailer after entering the Korean market in December 2014. IKEA's entry into Korea is possible to destroy the existing orders in the retail industry and reduce the profit of incumbent local players by realigning industry relationships. However, HANSSEM achieved rapid growth with the largest market share in the furniture market through its internal capabilities. The authors propose the main success factors in three ways: (1) residents-database including apartment floorplans in Korea, (2) high-quality human services provided by construction and A/S (After-sales Service), (3) channel diversification that provides comprehensive consultations (e.g., flagship stores, home shopping channels, stores in marts, and interior dealers). Especially, there have been various consumer needs in Korean market, such as creating their own stylish space economically. HANSSEM meets customer's needs by reinforcing the space-package (complete-interior is provided to customer in a package rather than combining individual piece of furniture) and opening showrooms, which makes customers freely experience the products and receive detailed consultations on interior designs by alleviating customers' difficulties in decorating their homes. Based on HANSSEM's outstanding activities and new investments, we look forward to seeing that HANSSEM will achieve its ultimate goal of maintaining the position of number one furniture company by attaining customer satisfaction through higher quality in Korea.

In this paper we apply the martingale approach, which has been widely used in mathematical finance, to investigate the optimal investment problem for an insurer under the criterion of mean-variance. When the risk and security assets are described by the L$\acute{e}$vy processes, the closed form solutions to the maximization problem are obtained. The mean-variance efficient strategies and frontier are also given.

This study examines the effect of managerial ownership on firm value in capital markets where outside governance mechanisms to discipline managers are weak or non-existent. We hypothesize that strong market forces in the U.S. confound the effect of managerial ownership on firm value, i.e., the convergence of interest argument. We test the hypothesis using data from 112 firms from Singapore Stock Exchange and 205 firms from the Stock Exchange of Thailand prior to the Asian financial crisis in 1997 when the market forces were weak, yet the investor protection was sufficient to prevent outright appropriation from management. For ease of comparison, we use methodologies from studies done on the U.S. sample firms during the same study period as ours. We find that, both in Singapore and Thailand, firm value is a function of managerial ownership, and the relation is of the famous inverted U-shaped. Moreover, the relation is robust under different model specifications. The results from Thai sample, with weaker market forces than in Singapore, lend support to many agency cost hypotheses advanced in the U.S. Our results provide useful implication for investors in emerging and frontier markets where outside governance mechanisms are yet to be fully developed.

It is estimated that the world market size of the outsourcing of information system will be 780 billions in 2004, and that of ASP, one of outsourcing markets, will be 24 billions in 2005. The domestic outsourcing market also has 6 times grown in 2001 compared to the size in 2000. However, there have been only a few systematic researches about information system outsourcing and ASP in Korea. Though the importance of ASP has been recognized, no business model has been examined. So, this research was done to survey the outsourcing of information system and the meaning/present status of ASP, and to consider several factors to successfully introduce this service to companies. Especially, this research focused on ASP.

To enforce the maximum residue limit for residual hexane (0.005 g/kg) in commercially available Korean vegetable oil, convenient and accurate quantification methods were investigated. Using dual surrogate standards, pentane and heptane were dissolved in ethanol, and then added to hexane-tree sunflower oil for setting up the calibration curve. Gas Chromatograph-Flame Ionization Detector with a porous layer open tubular column, indicated good chromatographic separation of hexane from other inhibiting matrix components. The lowest calibration level was $0.5\;{\mu}g/g$, not exceeding a relative standard deviation of 10% (RSD%), and 1.0\;{\mu}g/g$ not exceeding a deviation of 22% RSD% using heptane as an internal standard for the Static headspace analysis by using a headspace auto-sampler and manual injection, respectively. The residual hexane was detected in nine of the samples among 87 vegetable oil samples purchased on the local market.

This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).
