Purpose: Establishing a competitive advantage in the aviation market is essential as the competition among domestic airlines intensifies. Therefore, this study examined the management strategies of both large domestic airlines and low-cost airlines. Research design, data, and methodology: This study classified domestic airlines into Full Service Airlines (FSA) and Low Cost Carriers (LCC), examined each airline's current status and characteristics, and conducted case analyses of FSA and LCC based on Porter's generic competitive strategy. Results: The analyses determined that LCC primarily implemented a cost-advantage strategy, and FSA implemented a differentiation strategy. However, as competition intensified, FSA pursued cost-advantage strategies while establishing LCC through subsidiaries. There are various specific cost reduction methods, including service simplicity, scalability, high utilization, low landing fees, low-cost unit, and point-to-point flight strategies. Conclusions: LCCs are focusing on cost advantage strategies that reduce costs; however, the FSA also runs special price events that are as good as LCCs and are comparable to LCCs on some routes. Furthermore, LCC has recently expanded its mid- and long-distance routes, making competition for long-distance routes with major airlines unavoidable.

The International Astronomy Olympiad (IAO) was established by the Euro-Asian Astronomical Society in order to disseminate astronomical knowledge, promote international cooperation in astronomical education area and recognize the importance of astronomy in far-reaching field of science and human culture. The first IAO competition was held at the Special Astrophysical Observatory of the Russian Academy of Sciences located in the north Caucasus of Russia in 1996. Since then, it has been held every year. This paper describes the present status of the IAO main regulations regarding its operation and major results by year, related institutions, and organizations. We created a scientific inquiry framework to analyze past IAO problems in the recognitive aspect in order to measure levels of the scientific knowledges and the scientific thinking abilities. Through this analysis, we can understand the current status of the IAO, and examine the future direction of Korea Astronomy Olympiad. Also, we can make preparation for the IAO competition and the education of delegates.

In this study, a number of distance-dependent competition indices on tree-level which incorporate the tree sizes and distances to competitors, and traditional stand-level density measures were estimated from the data compiled with position-dependent survey in a Pinus densiflora stand. The performance of the estimated competition indices was examined by comparing the relationship with the diameter growth, and a dbh growth function, in which the competition index is considered as a one of influence factors, are developed. In the searching method of competing trees, the competition index estimated with $30^{\circ}$ competition interrupting angle showed the highest correlation with the annual dbh growth, while the expanding the competing zone distance had no significant effect on the performance of competition index in estimating annual dbh growth. The most of the examined stand-level competition indices, based on distance-dependent single-tree competition indices, were evaluated to describe similarly the stand competition status. As a result of partial correlation analysis in which the effect of age and site index are eliminated, Alemdag's mean competition index and relative spacing index were determined to have the highest correlation with dbh. The relative spacing index, which can be easily measured in field without measuring the position of individual trees, was considered to be a better suited one for estimating mean dbh of a stand. Among distance-dependent competition indices on tree-level, Hegyi's competition index showed the best performance in their correlation with annual dbh growth, if eliminated the effect of site index and dbh. This enabled to derive the following annual dbh growth function of individual trees which incorporate age, dominant height, dbh and Hegyi's competition index as influence factors : $$dbh^{\prime}=3.975362676{\cdot}age^{-1.099274613}{\cdot}ho^{0.199893990}{\cdot}dbh^{0.269430865}{\cdot}HgCI^{-0.353643587}$$ This function is coincided to the growth principle in which site index has a positive effect on the annual dbh growth, while high age or competition causes to reduce the annual dbh growth, and can be used as a function in single tree growth model.

Korea has a high proportion of self-employment. Many of them start the food business since it does not require high-techs and it is possible to start the business relatively easily compared to many others in business categories. However, the closure rate of the business is also high due to excessive competition and market saturation. Cafés and restaurants are examples of food business where the business analysis is highly important. However, for most of the people who want to start their own business, it is difficult to conduct systematic business analysis such as trade area analysis or to find information for business analysis. Therefore, in this paper, we predicted business status with simple information using Microsoft Azure Machine Learning Studio program. Experimental results showed higher performance than the number of attributes, and it is expected that this artificial intelligence model will be helpful to those who are self-employed because it can easily predict the business status. The results showed that the overall accuracy was over 60 % and the performance was high compared to the number of attributes. If this model is used, those who prepare for self-employment who are not experts in the business analysis will be able to predict the business status of stores in Seoul with simple attributes.

Because of a recent trend of the open and globalized world economy, international trade is getting bigger and there is a trade competition among many countries, resulting in competition between harbor industries. Therefore, as hub-port development of China, Japan and Taiwan is more actively progressing than any other times, Korea should prepare a powerful management system to take the initiative over them. Above all, a new recognition of the governmental officers in charge of political management about hub-port industry and early development of the northeast hub-port are needed. To maximize its distinctiveness from competitive ports, port sale should be actively managed. As well, as port functions are diverse, accompanied site development should be prepared. In conclusion, in order to improve functions of a port and develop the port as a general complex of physical distribution, the government should encourage the accompanied site development and support preparation of a customs-free area and a general system of physical distribution.

The competition between hospitals has become an issue for many hospitals because of the sudden increased number of health providers. As the marketing or customer management have become important factors as means of competition, a number of hospital have been considered or already adopted the coordination system. A system dynamics model is developed to see the effect of the hospital coordination system. This paper after briefly explaining the structure of the system dynamics model, discusses the roles of the hospital coordination system with examples. The system dynamics model quantifies through simulations the process of effects of coordination system on the number of customers, productivities of employees (nurses and doctors), and finally the financial status. As a conclusions of the simulations and their analysis, it is concluded that coordination system could be more effective than the investment to the facilities. Since the study is based on only one hospital case, it is limited. However, it explains the mechanism of the coordination system quantitatively as well as qualitatively.

As the necessity of customer relationship management (CRM) increases, measuring the performance of CRM have been actively discussed. Customer equity (CE) is regarded as an appropriate indicator for evaluating the outcomes of marketing activities. There are three drivers of CE: brand, value, and relationship equity. This study aims to investigate the impact of three drivers on customer satisfaction. Market competition is an environmental factor that affects the effectiveness of CRM. This study divides target firms into leaders and followers. This study found that the differential impact of CE drivers on customer satisfaction depends on the firm's status (leader or follower). Specifically, the brand equity driver significantly impacts the leader firm. However, the impacts of value and relationship equity drivers are bigger for follower firms. The above results suggest that firms need to build CRM strategies that consider the competitive situation of the market and their position.

Ihis landscape design was proposed for the Remodeling for the National Theater of Korea Competition. Today, the National Theater of Korea, located in Jangchoongfong, Joong-gu, Seoul, asks plans for renovation. The landscape design for the remodeling of the theater is conducted as part of comprehensive programs for its renovation. The Government sought design proposals through a design competition in April, 2002. The authors proposed a landscape design for remodeling the National Theater of Korea and won first place in the competition. The landscape design covers the following a survey of the present status, a site analysis, a schematic design, and design, development. In the authors'design, heavens, humans, earth and nature are symbolically expressed within the site. The outdoor spaces of the National Theater of Korea are organically composed of the following low spaces : 1) a field of creation; 2) a field of recreation; 3) a field of meeting; and 4) a field of contemplation. The field of creation consists of a main entrance, spaces for public performance and plays, spaces with symbolic water features, and resting areas. The field of recreation is composed of various exhibition spaces. The field of meeting consists of traditional Korean-style gardens and an outdoor cafeteria. The field of contemplation features lawns, grasses and trees, and provides an area for pedestrian strolling. The outdoor spaces of the National Theater of Korea would produce an atmosphere suited to a cultural and artistic place. In the spaces, people would perceive a unique sense of place through various types of fountains, pergolas, columns, walls, light poles and bollards. An example of the true meaning of a cultural space and a resting place is provided in these spaces. The renovated National Theater of Korea would be a new type of theater with regional context, cultural meaning, spatial identity, various amenities with symbolic images, function and beauty.

China has definitely been arising as the world's most powerful nation. By looking at general national power it seems that China's national prestige in 2011 is already way beyond Asia and even it closely catches up with the United States which is the most powerful nation over the world. The United states-centered world political order has begun to struggle by China's growth. Moreover, there has been an earnest competition arisen for the east-Asia sea supremacy between previous U.S. hegemony and arising China's power. East-Asia's ocean is the stage for this strife and it grows more serious. At this point, South Korea, one of the east-Asia country seeking the nation's stability and prosperity through its ocean, has come under the influence of this strife among the super powers of the world. The Author will closely examine the backgrounds and future opportunities of military competition between U.S. and China to analyze the influence of the power competition towards the security status of east-Asia especially South Korea.
