Logistics needs in Asia are surprisingly increasing due to rapid growth of China in Northeast Asia We are endeavoring to make an economic block in opposition to NAFTA and EU by economic revival, political stability, and easing of exclusive parts between countries as increasing of traffic infra such as asian highway, transcontinental railway in the region of Northeast Asia and as considering diversification of transportation mode. Now, Busan is not a final terminal of this business, and it is not a concreted level in considering an undersea tunnel between Korea and Japan as effort to extend to Japan. Therefore, this study performed an effect analysis which be affected to Northeast Asia and Korea in future by analysis and comparison of a cost and time required of marine transportation and railway before and after construction through course analysis and summary of discussed content until now for undersea tunnel between Korea and Japan. This result expects as a accelerative play for study cf undersea tunnel between Korea and Japan in future. In this result, we estimate that it is an effective things in a cost and time required if undersea tunnel between Korea and Japan is constructed, and we simply searched for theirs effects in the aspects of Northeast Asia, national balanced development, regional economic in Busan, and marine logistics.

This study measured the centripetal force and effective scope of the population spread from urban center and subcenters in order to diagnose the urban spatial structure of the formation of a multicentric city structure in Busan. The study analyzed the variability of the determination coefficient value (R square) with a negative exponential function derived from the population density model by extending the circular region into 5-km units. The aim of this study was to measure changes in the effective scope of the population centripetal force of the urban center and subcenter in 5-year intervals from 1995 to 2005 using census data. The explanatory adequacy of the population density function was examined with the bias of the function to calculate the distance error between the real location of the urban center and the optimal location, according to the population density function. To summarize the results, the value for the area of Jungangdong showed a continuous reduction, whereas Seomyeon (Bujeondong) maintained explanatory adequacy without a large change. As a whole, Busan was in the process of continuous diversification, in spite of its reduced population. Therefore, it appears necessary to strengthen the function of the urban center and subcenter and to supply adequate dwelling zones close to downtown to form a more efficient urban spatial structure. The results of the present study will be utilized as basic data for the formulation of a political approach to the efficient reorganization of spatial structure by correlating concrete spatial information with the population variability of Busan's urban center and subcenter.

This research is objective that we investigate the effects of transformational leadership type of the head of pre-school institution on its operation and management. In order to test, we selected the subject of 200 teachers at 50 preschools in Seoul city randomly and we measured leadership type of the head and the level of its operation and management to 174 pre-school teachers. Based on the collected questionnaire, simple correlation and multiple regression analyses were conducted to produce the following results: First, analyzed result, participants were higher recognition that the relationship between the institution head's transformational leadership and its operation and management, and between the two variable were significant static positive correlation. Second, we analyzed the difference between type of transformational leadership to the institution head's perceived by its teachers individuals variables. As a results, we found that the academic ability(a college to university graduation) was significant the ethical leadership and teachers gives a positive evaluation on the head's transformational leadership regardless of the teacher's background variables. Third, we analyzed the transformational leadership affect institution on its operation and management. its results, the transformational leadership was significant on its operation and management. In particular, it were affect according to the order, political leadership, educational leadership, cultural leadership. Our finding contribute that pre-school institution have to change consistently, and were asked higher quality by enhancing competition, politics and its operation and management. in order to it is important that there is transformational leadership of the head.
This is a study on the ecological view of Robert Smithson's reclamation projects. Smithson was a pioneer of Earth art in the late 1960's. Robert Smithson believed that he could transform industrial wastelands, such as an abandoned oil rig and a no longer used quarry, into "Earth Art." In the early seventies, he conceived of land reclamation as a new art form and called this art "Reclamation Projects." His attention regarding industrial ruin started from the American political and social situations in the 1960's. In the late 1960's, American society was in chaos from the right of movement of African Americans, the women's rights movement and from the strike for renunciation of the Vietnam War. The intellectual class seemed to believe that it was the destiny of a closed system's society to run in the direction of entropy. Smithson, who was skeptical about the system of American society, also thought that entropy was the proper diagnosis to describe America's situation in the 1960's. The 1960's civic movements like the civil rights movement and antiwar movements expanded into the environmental movements based on ecological views of the 1970's. The government had also started to worry about environmental pollution. Thus, the reclamation act was also established in 1972. Smithson believed that the relation between art and social background are closely related and affect each other. He was concerned with how art can join society, and the result was reclamation projects. Such reclamation projects lie on man-made wastelands, like abandoned oil rigs and no longer used quarries, which was an allegory of entropy. He also thought that Frederick Law Olmsted was a pioneer of earth art. The aesthetic category of Olmsted's view of landscape is to be based on the picturesque of Uvedale Price and William Gilpin. So Smithson, who considered Olmsted as his touchstone, also accepted the picturesque. Such reclamation projects aim to change with nature by adapting the creative power of artists to the ruin which has the highest level of entropy in industrial society. Smithson wanted this to become the bridge between man and nature. His reclamation project's aim, which shows the system interacting between man and nature as a network, is not different from the ecological view of the 1970's environmental movement.
At the Davos Forum in 2016, the Fourth Industrial Revolution, a reference to cloud Schwab, is dramatically changing our lives, and at its height, self-driving cars are emerging as the talk of the day. But there are still many hurdles to overcome before the nation can successfully introduce and establish self-driving cars. In particular, it is necessary to change the paradigm of the legal system centered on human beings to one that includes artificial intelligence. The stable operation of the self-driving car era requires drastic changes to the people-centric legislation system. That is, it is necessary to collect information on the total number of drivers of self-driving cars (what is available), general vehicles on general roads, civil and criminal liability issues in the event of traffic accidents, and collection of insurance problems concerning autonomous driving vehicles. In this study, a separate bill was proposed to address the various legal issues arising from the operation of self-driving cars from a legislative perspective by considering the domestic laws related to road transport, the current state of legislation on foreign soil and legal issues related to self-driving cars.
Due to recent climate change, flood damages have been increased, but it is difficult to construct large hydraulic structure for flood control such as dam because of environmental, economical and political problems. For this reason, several researches and studies have tried to use washland as an alternative of hydraulic facility. Because sizes of washlands are usually smaller than those of dams or reservoirs, there can be many available locations for washlands in a basin and proper combination of these locations can reduce flood disasters efficiently. However, in case there are many available locations for washland and many combinations to consider, it is very difficult to determine the optimal combination which yields to provide the maximum benefit. For the more, hydraulic approach that used in previous studies to calculate flood reduction effect needs a lot of time for calculation and sometimes can not give the final result. In this study, the flood reduction effect of washland is calculated by hydrologic approach and decision making model for optimal location of washland using genetic algorithm for determination of optimal solution is developed. The developed model has been applied to the Ansung River basin in order to examine the applicability and the application result shows that developed model can be used as decision making model for washland.
This study attempted to clarify (1) the meaning of 'people's livelihood (Minsaeng, 民生)' conveyed by the newspapers in Korean society and the specific matter it refers to, and (2) consider the discourse formed by the newspapers and what does and does not change in that discourse over the passage of time. Editorials were classified and analyzed based on the framework of Fairclough's critical discourse analysis(CDA). It was clear, from the political perspective, that the discourse was respectively formed and changed for each administration. The discourse on 'people's livelihood' was critical and at the same time generally negative, because it dealt with the important social incidents or controversies of the time. The discourse on 'people's livelihood' related to the massive social streams of Korea's democratization and globalization process. Whereas the discourse on 'people's livelihood' in the 1990s, seen from an economic perspective, tried to resolve labor strikes, inflation rate, housing problem, and financial crisis. The discourse in the 2000s changed to issues ranging from economic growth and distribution to bi-polarization problem, job creation, abolishment of non-regular employments, etc. The meaning of 'people's livelihood' produced in the editorials of the major daily newspapers is different from the word's dictionary definition as 'the people's lives'.
The forthcoming twenty-first century is at the mercy of information and culture. A quality of humanlife is under the control of a cultural level. A nation's creative culture and a cultural level represent all things about the nation; and a national image, as a whole result of culture, is enormously influential. This new era of culturalism gives us a significant responsibility for getting ready for the late industrial society by practically harmonizing rationality of modem culture with conception of traditional culture. Industrializing culture and culturalizing industry will be the most important strategy for existence in these days of borderless international competitiveness. Cultural products which is containing a nation's own culture can not only enhance the national image, but also become high value-added industry. While general products are developed for the purpose of convenient and practical use, cultural products are created with the intention of informing international society about a nation or a region. In order to confront with a global market system and a change of cultural environment, it is necessary to create a proper design with cultural inheritance for modem likes and senses, to produce the design on a commercial scale, and to strengthen its competitiveness on international markets. In order that a commodity is born, distributed throughout markets, and delivered to a final consumer, it is essential to understand complicated process such as development, distribution and marketing of products and to systematize each part. Although we should not neglect any part, a political and systemical plan or a distributional and marketing idea will be beside the point in this article. This article presents importance of traditional patterns as a Korean cultural image, and it shows the process of designing and developing products in order for traditional patterns to be utilized for products effectively. I expect that concrete activation and systematization for those works can be carried out successively.
Online communities, such as Internet portal sites and social media, have become popular since they allow users to share opinions and to obtain information anytime, anywhere. Accordingly, an increasing number of opinions are manipulated to the advantage of particular groups or individuals, and these opinions include falsified product reviews and political propaganda. Existing detection systems are built upon the characteristics of manipulated opinions for one particular time period. However, manipulation tactics change over time to evade detection systems and to more efficiently spread information, so detection systems should also evolve according to the changes. We therefore propose a system that helps observe and trace changes in manipulation tactics. This system classifies opinions into clusters that represent different tactics, and changes in these clusters reveal evolving tactics. We evaluated the system with over a million opinions collected during three election campaigns and found various changes in (i) the times when manipulations frequently occur, (ii) the methods to manipulate recommendation counts, and (iii) the use of multiple user IDs. We suggest that the operators of online communities perform regular audits with the proposed system to identify evolutions and to adjust detection systems.
The heterogeneity and complexity of malaria involves political and natural environments, socioeconomic development, cross-border movement, and vector biology; factors that cannot be changed in a short time. This study aimed to assess the impact of economic growth and cross-border movement, toward elimination of malaria in Yunnan Province during its pre-elimination phase. Malaria data during 2011-2016 were extracted from 18 counties of Yunnan and from 7 villages, 11 displaced person camps of the Kachin Special Region II of Myanmar. Data of per-capita gross domestic product (GDP) were obtained from Yunnan Bureau of Statistics. Data were analyzed and mapped to determine spatiotemporal heterogeneity at county and village levels. There were a total 2,117 malaria cases with 85.2% imported cases; most imported cases came from Myanmar (78.5%). Along the demarcation line, malaria incidence rates in villages/camps in Myanmar were significantly higher than those of the neighboring villages in China. The spatial and temporal trends suggested that increasing per-capita GDP may have an indirect effect on the reduction of malaria cases when observed at macro level; however, malaria persists owing to complex, multi-faceted factors including poverty at individual level and cross-border movement of the workforce. In moving toward malaria elimination, despite economic growth, cooperative efforts with neighboring countries are critical to interrupt local transmission and prevent reintroduction of malaria via imported cases. Cross-border workers should be educated in preventive measures through effective behavior change communication, and investment is needed in active surveillance systems and novel diagnostic and treatment services during the elimination phase.
