Because of its unique characteristics, the construction industry tends to be affected by economic environment more than any other industries. The domestic construction industry was forced to change its management pattern and system when it went through the foreign currency crisis, and since then, the construction industry has been growing in terms of quality over last 10 years, breaking from the quantitative performance-oriented growth in the past. The study was intended to integrate the financial data of the companies during the period before and after the foreign currency crisis so as to analyze the effect of environmental changes on management performance of the companies. It was aimed at evaluating the changes to the stability, profitability and the growth potential, and collecting the data on variation of the market scale, price of resources such as material and labor and the financial environment, thereby analyzing the correlation with the management performance. The study, to deal with the difficulties which are anticipated, like the foreign currency crisis experienced in the past, was also intended to identify the correlation between the economic conditions and the performance of the construction companies, using the experimental data in the past.

This paper deals with the deepening global competition of talent between regions as well as states in the process of globalization and the transition toward knowledge-base economies. This study figures out the global geography of talent by examining the distribution and spatial changes of the talent at the global scale. It also analyzes key policies and mechanisms by investigating various countries' policies to attract global talents. Finally this paper points out the limitation of current city-regional development strategies for global competition in that it lacks the consideration of the importance of the talent. In response to that, we propose the strategy to focus on the quality of place to attract the global talent for the city-region development.

With the increasing number of high-rise and large-scale buildings, modern buildings are becoming intelligent, and are incurring high construction costs and requiring careful maintenance. Maintenance works for high-rise buildings significantly depend on human labor, unlike other construction processes that are gradually being automated. The resulting accidents may produce very high social and economic losses. To address this problem, herein, this paper proposes robotic building maintenance system using multi-robot concept, in specific, cleaning a building facade which is directly subjected to minimize human labor; that improves the process efficiency and economic feasibility. The sensor for detecting contamination of building's outer-wall glass is proposed; Kalman filter was used for estimating robots' status with the contamination of the window glass. Task allocation of the sensor based multi-robots for an effective way of task execution is introduced and the feasibility was verified through the simulations.

This study aims to examine the structure and meaning of the perception of rural amenity which rural and urban residents have. Many Lickert scaled questions measure how much important the respondents think about the various items related to rural amenity respectively. It reveals that there is not meaningful difference in the relative importance among three upper dimensions composing the construct of rural amenity, historic-cultural dimension, natural environmental dimension and living condition dimension. This means that our respondents are not willing to pursue historic-cultural aspects and natural environmental aspects at the risk of living condition being able to enjoy comfortable and affluent opportunities. And also, this results reveals that people might have a quite different perception compared with academic discourse putting much weight on historic-cultural dimension and natural environmental dimension.

Purpose: The purpose of this study was to examine the levels of self-esteem and resilience and to investigate factors affecting on the resilience among nursing students. Methods: The subjects for this study were 175 nursing students and the data were collected from November 15 to December 20, 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Subjects' mean scores of self-esteem and resilience were 3.60 and 3.78, respectively, on a 5-point scale. There were significant differences in the level of resilience among grade (F=3.30, p<.001). The post-hoc test showed that the resilience level of the fourth-grade subjects was significantly higher than that of the third-grade. There were no significant differences in the level of resilience according to gender, religion, residence type, and economic level. Self-esteem was positively correlated with resilience (r=.80, p<.001) and economic level (r=.20, p=.007). The results of the multiple regression analysis showed that self-esteem was a significant predictor for resilience (β=.81, p<.001) which explained 64.7% of the total variance. Conclusion: Self-esteem was an significant factor for nursing students' resilience. Therefore, intervention strategies should be developed for nursing students to improve their self-esteem.

The purpose of this study is to propose and test a model of customer retention in Internet shopping malls when switching barriers and comprehensive customer value exist in terms of economic and experiential aspects. The literature about customer retention propose that switching barriers are important factors other than satisfaction influencing customers' intention to remain with a specific supplier. The switching barriers mean anything that makes customers' defection difficult or costly and are consisted of perceived switching costs, attractiveness of alternatives and virtual relationships. The Customer Value Scale by Mathwick(2001) is applied to this study as economic value, shopping efficiency, service excellence, aesthetic appeal and playfulness(Zeithaml, 1988; Holbrook, 1994). The analyses showed partial support for the affirmative effect of customer values and switching costs and full support for the affirmative Influence of satisfaction on repurchase intention in the Internet shopping mall environment. But the attractiveness of alternatives and virtual relationship did not have a significant Influence like the result of Jones(1998)'s study of the service industry.

This paper aims to describe port competition in East Asia and the Korean government's port strategy. In doing so, the paper provides an overview of global changes in international trade, the shipping industry and the port business. It also delineates the status of port competition in the region. Particular examples are taken from the competition among the ports of Hong Kong, Singapore, and Malaysia, as well as those of Pusan and Kwangyang, Kaohsiung, Kobe, and Shanghai and Yantian. The port competition in East Asia is reviewed and classified in two groups: north-tier competition among traditional major players, such as Kobe and Pusan, and dark horses such as Shanghai, Kwangyang and perhaps Yokohama; and south-tier competition among the three traditionally big players Kaohsiung, Hong Kong and Singapore, and the relative newcomers of Yantian in China, and Tanjung Pelepas In Malaysia. Due to the enlarging of ships and expansion of port activities, the boundary between the two tier frontiers breakdown, or they may even merge, into one grand frontier, in the foreseeable future. Although it appears that Asian ports are not being very aggressive in preparing for the future of mega-carrier in their plans, it is true that China, Korea and Taiwan are moving full steam ahead in comprehensively developing their container ports on a large scale. It therefore seems to be the perfect time for rival ports to explore a port alliance strategy to fight against the trend toward alliances between of many shipping lines.

Port marketing using websites in the e-business environment is essential in response to the competition to become hub ports, especially since shipping companies, ports' major customers, are being pressed by shippers to reduce logistics costs and introduce large ships to realize economies of scale, thereby reducing the number of ports of call. In this sense, this study intends to approach the port industry from the perspective of e-business and suggest vitalization methods using Gwangyang Port websites(6C; contents, community, communication, connection, commerce, customization) as one of the ways to turn it into Northeast Asia's hub port of logistics.
