The environment of the access network service market is characterized by uncertain demand and various competing alternative technologies. In Korea, despite the introduction of competition, dominant Public Network Operator(PNO) still leads the market. Therefore, the decision of PNO has a great impact on the access network evolution. In this paper, we propose an model which aims to reduce risks and both investment and operating costs, to cope with the uncertain demand and technology evolution. We expect this model to provide a tool analyze risks and evaluate various strategies on the network evolution.

This study examines the relationship of the industry-specific factors that effect innovation of manufacturing technology and the market share within the defense industry. Since the establishment of the basic defense industry framework in 1973, there were numerous interactions of the industry-specific factors of the defense industry structure with the technological innovation and market organization of the defense industry. During last three decades, the domestic defense industry has achieved the considerable level but the framework of the basic system has not developed much in areas of the military science and the defense manufacturing technology. Industry-specific factors were formed in the process and appeared in a variety of behavioral characteristics as subsystems. Currently, there IS a growing trend where the management of defense industry is gradually deteriorating due to limitation of the domestic industry-specific factor (e.g. defense technologies, amount of demand, etc.). If there is a prominent imbalance of the industry-specific factors. it can trigger the potential problem of conflict, lack of cooperation and control, slowing the growth of the manufacturing technology thereby diminishing the market and deteriorating the defense supply/demand relationship. In a research conducted by Joe S. Bain, Bain analyzed the relationship of the traditional industrial organization where industry-specific factor(S) not only impacts the conductor(C). And, conductor(C) influences the shaping of the performance(P) of relationship of the traditional industrial organization. Consequently, the researcher has identified the demand monopoly, barriers to entry, and market competition with comparison of defense industry issues. These defense issues were three industry-specific factors identified, which are 1) The demand monopoly and The entry barriers to new market competition, 2) the industrial technical factor to a production technical competitiveness and a market sharing competitiveness, 3) the probability factor to revolution for military affairs(RMA) and a R&D production. According to baseline with these factors, the following research model is established from the special companies group(Group A), the systematization companies group(Group B), and the general companies group(Group 0. The hypothesis is that if there are more industry-specific factors, then there will be more relationships of defense industry relation statutes. This research is an empirical study on the relationship that the industry specific factors effects the innovation of manufacturing technology and the shaping of the market in the defense industry. Moreover, the existing models to evaluate the industry specific factors of the defense industry IS much to be desired with the controlled statistical analysis of the result. It is vital to study on current situation with suggesting alternative strategy to the efficient strategy. The descriptive analysis approach analysis is conducted with SPSSWIN to conduct reliability test, factor analysis, correlation analysis, cross-tabulation analysis, one-way ANOVA, and multiple regression analysis. However, there were some limitations of the survey such as the rigidity of concept about the technical factors and various market management factors. The wishes is that the decision-maker could be utilized these defence industrial factors to formulate efficient defence policy and strategy in the future.

While the housing transaction price of Seoul tends to be stagnant or declining in line with the housing market recession since 2007, the jeonse price keeps continual increase. Such flow of jeonse price change has a serious influence on ordinary person's housing stability seriously. Therefore, it is very meaningful in terms of social policy to analyze the trend of recent jeonse price change. This study aims to have an empirical analysis of structural characteristics of the trend of recent jeonse price change. After the review of various previous studies, this study selected housing jeonse price index, non-sold house quantity, jeonse vs. transaction price rate, and housing construction performance as analytical variables, and employed monthly time series resources from January 2007 to April 2011. As a result, when the housing supply reduced, the potential quantity for jeonse market reduced that occurred unbalance of supply and demand in jeonse market. In turn, it caused the increase of jeonse price. And, in case of jeonse vs. transaction price rate change, the rate increased which means the increase of required rate of return of invested demand. As such, the increase of market risk degenerates the investment sentiment which caused the reduction of quantity for jeonse market as a submarket.

As an emerging market in central Asia, Kazakhstan's housing market is witnessing increasing demands. Though Korean construction industries have attempted to take advantage of this opportunity, inadequate understanding of the local living demands have kept the industries from successfully establishing themselves in the foreign context. The goal of this research is to derive architectural planning implications regarding the living demands by investigating changes being made to the housing structure. By analyzing 11 apartment unit plans, it was found that Kazakhs had a living demand for more spacious living rooms and functional spaces. In the effort to improve the livingroom environment and usability such as enlarging the livingroom, removing the living room wall for open space or expanding the inner space facing outside is understood that the living room is considered as an important space. The fact that spaces such as dress rooms and utility rooms are being added in the housing market, reflects the demand of functional spaces. These demands are considered as the reflection of the traditional life style of nomad culture and the cold local climate. Therefore, it can be said that the apartment unit plans distributed in the Korean housing market are quite compatible with the Kazakh housing market since they offer spatious living rooms, while the latter founding implies the changes that ought to be made for a successful establishment in the foreign market.

Purpose - The movie market has the characteristics of being a perfectly competitive market as well as a pure monopolistic market at the same time. This is because there are competitors in the industry but prices, although not fixed, have not changed a lot. Price competition may not have spread, but the competition is focused on artistic value, and the degree of box office success is most important. The artistic value is determined in the course of the production process. However, the degree of box office success is dependent upon the marketing manager. The marketing strategy represents the difference in the standard or quality of the movie. Inherently, the marketing manager adopts the entertainment strategy based on the quality of the foundation of the completed movie. At this time, the marketing manager knows the pertinent information (high quality/low quality) regarding the movie. This research study tries to reveal what should be the reasonable movie marketing expense, dependent on the quality of the movie. Research design, data, and methodology - Using a game scenario with different market players, the goal of the research analysis is to find out the following. First, the marketing expense is determined to maximize the profits after film production. Second, after the production costs are already committed, the manufacturer gets to choose the marketing level. At this time, there will be a profit maximization point, considering the competition. The premise of the research is as follows: if it is a good movie of quality, positive word of mouth increasing the audience continuously slows down the speed of the demand curve. If the movie quality is bad, the negative word of mouth decreasing the audience gradually hastens the speed of the demand curve. On the marketing side, when the manufacturer invests heavily in the marketing expense of the movie, consumer expectations increase to drive up the audience numbers. On the other hand, it is difficult to improve the profits excessively. When the manufacturer invests in marketing a little bit, the marketing expense is only relatively committed, therefore a lot of demand cannot be gained. Results - If a fixed market share is in a competitive situation, a low quality manufacturer expends relatively more marketing expense. If the situation assumes two manufacturers spend the same for the cost of production, the high quality manufacturer takes more profit. If the manufacturer expends less marketing budget to save costs, the optimum profit cannot be achieved since the other party (opponent) grabs the initial market share. Conclusions - In conclusion, investment is essential for market share to increase. We must refrain from a zero-sum game and have models where the game participants pursue the creative profits together. In the current film industry, there is the dominating logic of winner and loser but we have to create a film industry environment where the participants can be altogether satisfied and live together.

국내 컨테이너 물동량 증가로 이를 처리하는 하역산업 증가하였다. 하지만 1999년 이후 하역요율의 신고제 전환과 시설 공급 과잉으로 인해 하역사간의 과도한 요율경쟁이 발생하여 2015년 기준 컨테이너 하역 요율이 2000년에 비해 절반 이하로 하락하였다. 이에 본 연구에서는 하역 요율의 하락이 항만 물동량 수요에 영향을 미쳐 항만 하역산업의 시장을 확대 시켰는지? 아니면 과도한 요율 경쟁으로 인해 소비자잉여가 오히려 축소되었는지를 경제학적으로 분석해 보았다. 이를 위해, 본 연구에서는 기존에 항만부문의 경제적 가치를 추정한 연구에서 사용한 직접추정방식이 아닌 수요함수를 이용한 추정방식을 제시하였으며 소비자잉여 추정을 위해 타분야에서 주로 사용된 알렉산더방식 외에 힉스의 수요함수를 이용한 하우스만방식을 이용하여 추정의 신뢰성을 높였다. 그 결과 컨테이너 수출입 수요에 비해 하역 요율이 과다하게 하락하여 소비자잉여를 포함한 하역산업의 경제적 가치는 오히려 하락하는 것으로 나타났다. 한편, 향후 환적 컨테이너 물동량을 포함한 경제적 가치추정에 관한 연구가 진행되어야하며 나아가 항만산업 전체로 확대하여 현재 항만부문 예비타당성 조사 표준지침에서 이용되고 있는 경제적 편익 방식을 보완할 수 있어야 하겠다.
