This paper provides the current status of weed science and prospects for the development of weed science based on the research trends presented at the 26th Asian Pacific Weed Science Conference in 2017. Approximately 458 researchers from 25 countries, including Korea, participated in the conference and presented 325 papers in 20 research areas. Major research topics were herbicide resistance, herbicide use, herbicide development, weed ecology, allelopathy, weed management, and exotic weeds. Particularly, there were many presentations and interesting to researchers about the development and use of new herbicides, such as florpyauxifen-benzyl ester, triafamone, fenquinotrione, and tolpyralate. Development of new herbicide formulations and spray methods were suggested as a solution for the population decline in rural area and low labor quality especially in Asia and Pacific regions. In future weedy rice and exotic weeds will be a serious problem in this area so we need to cooperate to make good technical and practical solutions.

Due to the global warming and unstable abnormal climate changes, water resources differences between regions and water shortage are occurring. Therefore, the water resources management is becoming more important for the stable securement of future water supply and demand. Researches on Smart Water Grid (SWG), which is considered as a new method, that can stably secure and maintain the water resources, are actively being conducted but it is still in infancy. Thus, this study aimed to design SWG simulator based on GIS in order to provide integrated water information in web environment. The user's requirements were analyzed for system development and important functions such as SWG current situation checking, future prediction, filtration plant situation checking functions were designed and data expression techniques using GIS and HTML5 were applied to enhance the understanding of the users. Also, when the emergency situations occurred, the solving process of the situations are reproduced to check the solution process using scenario reproduction functions. Use-case, class, sequence diagram, which are a design for real system development and defines the system usage contents of users, were written, and the story board was written to check the final development contents. This study designed a SWG simulator in order to support the water maintenance reacting to climate changes. The development of system is expected to help securing information to deal with emergency situations such as water shortage and help the decision maker to make decision through reproduction of scenario. The major functions were designed for the convenience of water resource manager and producer but new contents for consumers must be developed to enable duplex information transmission.

The present study aimed to derive decision factors for residency in the hinterland of Incheon New Port that is undergoing the development of port hinterlands and changes in leasing methods considered from the perspective of companies and analyze the priorities of determinants for residency through Fuzzy-AHP in order to present a direction to activate companies entries into the hinterland of Incheon New Port. When the comprehensive rankings of determinants for residency in the hinterland of Incheon New Port, rent levels among cost factors took the highest ranking with a value of 10.2% followed by the throughput of the port among market factors with a value of 8.2%, the scale of the market on the background with a value of 7.3%,, reduction in inland transport costs among cost factors with a value of 7.1%, connectivity to inland transportation networks among locational factors with a value of 6.7%, and designation as a free trade zone and the scale with a value of 6.4%. When seen from the viewpoint of companies to determine whether to move into the hinterland of Incheon New Port, the rent level should be provided to be more attractive compared to the hinterlands of ports in other regions. In addition, inland transportation costs which are a matter of the most serious concern of shippers in the capital region should be reduced and sea routes that can directly connect Incheon New Port to US ports and European ports should be opened.

This study analyzes the current status and performance of regional industrial policy in the face of the weakening industrial competitiveness under the global trend of the 4th industrial revolution and suggests the policy direction that regional industrial policy as a new national growth strategy. This study focuses on the suggestion of new regional industrial policy framework under new policy environment based on literature review. We propose a new industrial policy framework that simultaneously pursues equality between regions and efficiency within the region at the same time. As a core policy recommendation, we suggest first, establishing the region-centered industrial policy governance, second, strengthening planning function of local government through human resource development and institutionalized national government consulting, and the third, constructing lifestyle industry-ecosystem based on cultural asset and identity of region, fourth, utilizing Smart City, as a platform for participatory innovation, entrepreneurial and capital attraction, and cultivating new industry based on public procurement and data. Main suggestions of this study would be a new guideline coping with the declining industrial competitiveness and the Fouth Industrial Revolution. Details would be necessary.

Busan Port, Korea, is a region that must take integrated measures against problems such as the excessive handling of cargo volume, the intensification of port congestion, and the construction of a new port to improve port competitive power. In particular, if a great deal of function in the existing area of Busan Port transfers to a new port, then the problems of port redevelopment will occur as shown in the cases of port developed countries explained hereafter. For Korean ports, port redevelopment in a port zone is implemented for improving the port productivity that targets a local area, but the entire and systematic port redevelopment is not accounted for. Focused on this point, the paper is to present the directions for full-scale port redevelopment of the existing zone of Busan Port. The findings are as follows: First, the region of Busan is divided according to a regional classification that is necessary for port redevelopment. Thereby, 4 zones, total 26 regions of redevelopment were selected. Second, overseas case studies were considered for port redevelopment. From these same studies, appropriate types of port development in Korea were extracted and presented. Third, the status and problems of the selected redevelopment regions were analyzed, and types of port redevelopment were assigned. This study was not applied to the strict evaluation technique by quantitative analysis, but the concept and directions for unprecedented port redevelopment were first defined and established. It is significant to select target areas for redevelopment by regional classification and present directions for developing each region by choosing Busan Port as a real case study. This initiation will greatly contribute to the succeeding study.

Over the past 20 years new and small firms have been identified as significant components of economic strategies for job and wealth creation. Implicit in these strategies has been the search for policies which will increase the supply of new firms, and will encourage established firms' growth. Yet the majority firms spend the whole of their economic life within the small firm sector. The aim of this paper is to suggest a multidimensional approach to the understanding of the comparative characteristics of the small firm by providing evidence as to the factors which describe firms of different sizes, regions and industries. And I discuss in the context of policy options for regional economic development in Korea. The results from the analyses are summarized as follows. The size of the small firms in the sample measured in terms of both number of employees and sales revenue are characterized by regions, export performance and R&D. There is also some indication that growing firms may develop more complex environment. These results are based upon a multi-dimensional analysis of the strategic profile of a sample of small firms using KIS. From this observation of the firms during the data collection period, this is a conclusion that I find intuitively appealing.

The demand for beef as a protein source is increasing worldwide, although in most countries beef accounts for considerably less than half of total meat consumption. Beef also provides a highly desirable eating experience in developed countries and, increasingly, in developing countries. The sustainability of beef production has different meanings in the various geographical and socio-economic regions of the world. Natural resources including land mass and uses, rainfall and access to livestock feed, and the robustness of the economy are major determinants of the perception of beef sustainability. In this overview of the 2016 International Symposium on "Future Beef in Asia" and this subsequent Special Edition of the Asian-Australasian Journal of Animal Sciences on "Current Situation and Future Prospects for Global Beef Production", the contributions have been grouped into the following categories: Countries in Southeast Asia; Europe; and Countries producing highly marbled beef for export and/or domestic consumption. They also include reference to Special Topics including marbled beef production, and use of "omics" technologies to enhance beef quality assurance. Among these broad categories, notable differences exist across countries in the production and marketing of beef. These reflect differences in factors including natural resource availability and climate, population size, traditional culture and degree of economic development including industrial and technological developments. We trust that the International Symposium and this Special Edition on Current Situation and Future Prospects for Global Beef Production, the contents of which that are briefly summarized in this paper, will serve as a valuable resource for the livestock industries, researchers and students with an interest in enhancing the prospects for sustainable, efficient beef production that satisfies the growing size and complexity of consumer demands and markets for beef.

To avoid premature damage to the connection joints of a conventional precast concrete shear wall, a new precast concrete shear wall system (NPSW) based on a plastic damage relocation design concept was proposed. Five specimens, including one monolithic cast-in-place concrete shear wall (MSW) as a reference and four NPSWs with different connection details (TNPSW, INPSW, HNPSW, and TNPSW-N), were designed and tested by lateral low-cyclic loading. To accurately assess the damage relocation effect and quantify the damage and deformation, digital image correlation (DIC) and conventional data acquisition methods were used in the experimental program. The concrete cracking development, crack area ratio, maximum residual crack width, curvature of the wall panel, lateral displacement, and deformed shapes of the specimens were investigated. The results showed that the plastic damage relocation design concept was effective; the initial cracking occurred at the bottom of the precast shear wall panel (middle section) of the proposed NPSWs. The test results indicated that the crack area ratio and the maximum residual crack width of the NPSWs were less than those of the MSW. The NPSWs were deformed continuously; significant distortions did not occur in their connection regions, demonstrating the merits of the proposed NPSWs. The curvatures of the middle sections of the NPSWs were lower than that of the MSW after a drift ratio of 0.5%. Among the NPSWs, HNPSW demonstrated the best performance, as its crack area ratio, concrete damage, and maximum residual crack width were the lowest.

This paper considers the possibilities of health promotion from the following perspectives; (1) IUHPE, (2) socio-cultural similarities, (3) action research, and (4) learning from our past. 1. The IUHPE values decentralized activities through regions, and countries such as Japan, Korea, Hong Kong, Taiwan and China belong to NPWP region. Since IUHPE World Conference was held in Japan in 1995, Japan used to occupy more than 60% of NPWP membership. After 2001, membership is increasing rapidly in Chinese speaking sub-region. The transnational collaboration is still in its beginning phase. 2. Confucianism is one of key points. Confucian tradition should not be seen only as obstacles but as advantages to seek a form of health promotion more acceptable in East Asia. 3 Within the new public health framework, people are expected to create and live their health. However, especially in Japan, the tendency of 'lacking of face-to-face explicit interactions' is still common at health-promotion settings as well as academic settings. Therefore, the author tried participatory approaches such as asking WIFY(interactive questions designed for subjects to review their daily life and environment) and as introducing round table interactions. So far, majority of participants welcome new trials. 4. The following social phenomena are comparatively discussed after Japanese invasion and occupation of Korea ended in 1945; status of oriental medicine, separation of dispensary services, and health promotion specialist as a national license. In contrast to Japanese' tendency of maintaining the status quo and postponing of substantial social change, trend toward rapid and dynamic social changes are more commonly observed in Korea. Although all of above possibilities are still in their beginning stages, they are going to offer interesting directions waiting for further challenges and accompanying researches.

The continuing enlargement, deepening integration of EU and penetration of extra-EU enterprise into EU market are forming a new geographical restructure of the production system. In this paper, I analyse the changing geography of the EU automotive production system. The globalization and regionalisation of production activity intensify a competition among the enterprise. The European automotive production system changes to a platform system and a modular system for a diminution of productive costs, a development of various products and a frequent innovation of products. The European automotive enterprise is restructuring geographically the production functions and products in order to promote efficiency on a new production system, enlarged production space and intensified economic integration. The European automotive industry tends to a spatial specialization and agglomeration according to the locational factors of production functions and products and the locational condition of regions. This intensifies the geographical hierarchic structure of production activity between the core and the periphery.
