  • In this paper, we propose a pioneering concept of DPD(Disaster Prevention Design) to realize a securable society in the future. Features of danger in the future society are expected to be diverse, abrupt occurring, large scale, and complicated ways. Due to increment of dangers with their features of uncertainty, interactivity, complexity, and accumulation, human-oriented design concept naturally participates in activities to prevent our society against disasters effectively. We presented DPD is an essential design activity in order to cope with dangers expected in the future societies as well as realize securable environments. DPD is also an integrated design aids including preemptive protections, rapid preparing, recovery, and interactive cooperation. We also expect these activities of DPD is effective for generation of new values in the market, satisfaction of social needs, expansion of design industry, and a novel chance for development in the future society. Throughout this paper, we submit various aspects of DPD concepts including definition, classification, scope, necessity, strategy, influencing elements, process, and its principle. We expect these concepts will be the seed and/or basement of DPD research for the future works. For the direction of study for DPD in the future, we emphasize alarm system for preemptive protection rather than recovery strategy for the damage occurred. We also need to research about progressive prevention techniques and convergence with other areas of design. In order to transfer the concept of product design from facility-oriented mechanism to human-oriented one, we should develop new kinds of city basis facilities, public-sense design concepts referred to social weak-party, e-Learning content design preparing disasters, and virtual simulation design etc. On the other hand, we have to establish laws and regulations to force central and/or provincial governments to have these DPD strategies applying their regional properties. Modern design activities are expanding to UI(user interface) content design area overcoming the conventional design concept of product and/or service. In addition, designers are recognized as art directors or life stylists who will change the human life and create the social value. DPD can be divided into prevention design, preparedness design, response design, and recovery design. Five strategies for successful DPD are Precaution-oriented, Human-oriented, Sense-oriented, Legislation, and Environment Friendly Strategies.

  • PURPOSES : This study aims to examine the differences between the existing traffic demand forecasting method and the traffic demand forecasting method considering future regional development plans and new road construction and expansion plans using a four-step traffic demand forecast for a more objective and sophisticated national highway maintenance. This study ultimately aims to present future pavement deterioration and budget forecasting planning based on the examination. METHODS : This study used the latest data offered by the Korea Transport Data Base (KTDB) as the basic data for demand forecast. The analysis scope was set using the Daejeon Metropolitan City's O/D and network data. This study used a traffic demand program called TransCad, and performed a traffic assignment by vehicle type through the application of a user equilibrium-based multi-class assignment technique. This study forecasted future traffic demand by verifying whether or not a realistic traffic pattern was expressed similarly by undertaking a calibration process. This study performed a life cycle cost analysis based on traffic using the forecasted future demand or existing past pattern, or by assuming the constant traffic demand. The maintenance criteria were decided according to equivalent single axle loads (ESAL). The maintenance period in the concerned section was calculated in this study. This study also computed the maintenance costs using a construction method by applying the maintenance criteria considering the ESAL. The road user costs were calculated by using the user cost calculation logic applied to the Korean Pavement Management System, which is the existing study outcome. RESULTS : This study ascertained that the increase and decrease of traffic occurred in the concerned section according to the future development plans. Furthermore, there were differences from demand forecasting that did not consider the development plans. Realistic and accurate demand forecasting supported an optimized decision making that efficiently assigns maintenance costs, and can be used as very important basic information for maintenance decision making. CONCLUSIONS : Therefore, decision making for a more efficient and sophisticated road management than the method assuming future traffic can be expected to be the same as the existing pattern or steady traffic demand. The reflection of a reliable forecasting of the future traffic demand to life cycle cost analysis (LCCA) can be a very vital factor because many studies are generally performed without considering the future traffic demand or with an analysis through setting a scenario upon LCCA within a pavement management system.

In addition to that, this study also examines the influence of recent changes in the world economy and globalization, socio-demographic change, development of information technology on the future security market. The data reviewed in this study are official crime rates, socio-economic indicators, statistics from the National Police Agency and the business reports of a leading private security company. This study shows that several factors such as rising crime rates, lack of police capacities, national economic growth and rising household income have played important roles in development of Korean market. It is also expected to keep those positive affects on the future market. On the other side, in recent years, the security market seems to be increasingly affected by new social economic changes. Those are impact of last aging society, rapid increase of individual household and women's participation in labor market. These factors seem to increase personal and household needs for security service. World economy, globalization process and development of information technology are also deemed to give rise to social demands for surveillance, monitoring service and security in cyber space.

  • Gasification technology is one of the representative next-generation fossil fuel utilization technologies, converting low grade fossil fuels such as coal, heavy residue oil, pet-coke into highly clean and efficient energy sources. Accordingly, related market demand for gasification technology is ever increasing steadily and rapidly. A few years ago, conventional pulverized coal utilization technology had an edge over the gasification technology but the most significant technical barrier of limited capacity and availability has been largely overcome nowadays. Futhermore, it will be more competitive in the future with the advancement of related technologies such as gas turbine, ion transfer membrane and so on. China has recently completed a commercialization-capable large-scale coal gasification technology for its domestic market expansion and foreign export, rapidly becoming a newcomer in the field and competing with existing US and EU technical leadership at comparable terms. Techno-economic aspect deserves intensive attention and steady R&D efforts need to continue in organized, considering that gasification technology is quite attractive combined with $CO_2$ capture process and coal to SNG plant is economically viable in Korea where natural gas is very expensive. In the present paper, recent technology development and commercialization trend of many leading companies with coal gasification expertise have been reviewed with significant portion of literature cited from the recently held '2014 Gasification Technology Conference'.

  • Traditional medicine has been integrated into the national health system in many countries such as Korea, China, Taiwan, etc. Korea and China are most representative among them. The purpose of this study is to compare the policies on traditional medicine in Korea and China focusing on where it came from and where it is headed. In this regard, the study suggested the first analysis tool in the world for analyzing the policy of traditional medicine. The results of the study are as follows: First of all, the development process of Korean Medicine (KM) and Traditional Chinese Medicine (TCM) shows the same pattern, that is, both are influenced by its own national policies. Secondly, the difference between the two countries is due to the gap in the development status or the different aspects in national heath system. TCM is more vitalized in health system and has larger category, and stays ahead in globalization compared to KM. TCM covers Chinese medicine, integrative medicine and ethno-medicine. Korea emphasizes the role of KM in the declining birthrate and aging society, and promotes the overseas patient invitation strategy. China, on the other hand, establishes the medical system for emergency medical treatment and preventive treatment of major diseases and promotes overseas expansion of TCM service. In addition, Korea stressed the safety and distribution of herbal medicine, and China emphasizes production technologies. Korea has a strong medical device industry along with the government's fostering policy; however, in China, medical devices are in the R&D stage yet. Even though both countries promotes the drug development from natural products, Korea focuses on developing herbal cosmetics in application industry, but China shows weakness in policies on application industry. China shores up the foundation for culture and theory of traditional medicine, while Korea doesn't have related policy. Korea places emphasis on promoting collaboration with international organizations and medical volunteer programs, whereas China is more interested in mutual cooperation and real trade with other countries.

  • The north-west sea area of Cheju Island is where originate two layer current in the summer season. The case of the fishing operations in this sea area is almost impossible for normal expansion of the net gear for shooting net, and is happened to be frequent occasions for rise of tension suddenly in purseline by changes of the net shapes in the operation. Therefore, the safety of the operations is often obstructed by the above mentioned. In connection with the above, model experiments on the purse seine in the circulating water tank was carried out in comparison and analysis on the changes of tension in the pruseline by deformation of purse seine in the sea area of two layer current. THe results obtained are as follows;In the case of the required time for pursing of 20 minutes in the no current set, the increasing curve for tension of purseline can be expressed as:Y=0.0004x3+0.0098x2+0.3000x(r=0.9989)where Y is tension(metric tons) of a purseline, x is required time(minutes) for pursing. And, the maximum value of tension in this time was an increase of 31.3 percent at 15 minutes, and was a decrease of 30.3 percent at 30 minutes than that of 20 minutes.When the bottom margin of net is held on the position in velocity of 0.5 knot at three-eighths of net in the bottom current to the net height, the maximum tension of the required time for pursing of 30 minutes in tight set and loose set were decrease of 29.5 percent and 28.7 percent respectively than that of 20 minutes.The work load during the required time for pursing of 20 minutes were calculated 5.79×106 kgf·m in no current set, 7.89×106 kgf·m in tight set and 5.15×106 kgf·m in loose set, therefore it was an increase of 22.3 percent in tight set, and was a decrease of 11.1 percent in loose set than that of the no current set. Where tight set and loose set is a range of the bottom current with velocity of 0.5 knot at three-eighths of net to the net height.

  • This paper investigates the possibility of expanding pay-for-performance (P4P) program as a provider payment system, in terms of financial, economical, and political sustainability. In order to expand the sustainable P4P, P4P should have usefulness in terms of economic value as well as efficiency in the financial aspects of health care. More importantly, the P4P would be politically sustainable only when both providers and consumers can accept. Korea's healthcare system seems to have logical ground for the P4P program financially and economically. However, how well the P4P can work remains to be proven in its implementation. After 43 tertiary hospitals applied the P4P program for acute myocardial infarction (AMI) and C-section in 2007, the number of hospitals adopting the P4P program for AMI and C-section has increased to 316 in 2011, and an incentive for hospitals applying the P4P has risen to 2% from 1% of health insurance benefits. This shows that the P4P program introduced by Health Insurance Review and Assessment Service is quite successful. In addition, people are aware of the need for improved P4P program and policy alternatives have been already made. Therefore, it is very important to come up with politically supportable strategies that can make providers and consumers accept the P4P program while maintaining the governance of the existing health insurance policy. To this end, there are some tasks to be considered. First, the expansion of the P4P program should be placed on the agenda of the Health Insurance Policy Review Committee, the highest decision-making body, and a separate agency for P4P planning should be established. Second, for more efficient P4P program, the processes of review and assessment, currently carried out separately, should be integrated into a single process. Third, infrastructure to measure the quality of medical services should be sharply expanded. Fourth, the current paradigm for the assessment should be changed. Lastly, a P4P program for consumers should be considered. Given that the consumers in Korea can use medical services freely, the National Health Insurance Corporation could initiate the P4P program for consumers as a means of controlling excessive use of medical services and adjusting consumer's moral hazard.

  • This paper is to analyze citizens' consciousness on urban changes, especially focusing on changes in urban environment, spatial structure, and urban planning, of large cities in S. Korea, that is, Seoul, Daejeon, Daegu, and Kwangju in the 1990s. Some significant points can be described as follows. First. The most important factor influencing on the change of urban spatial structure was the expansion of residential area inner and outside of cities promoted by the traditional construction industry, and not development of high-tech industries and their complex or location of multi-national firms which can be emphasized as major factors of new urbanization process of global cities. Secondly, citizens seem to have experienced improvement and deterioration of urban environment simultaneously, emphasizing regulatory environmental policy on the one hand, and recognize the necessity of sustainable urban development within given environmental capacity and restoration of destructed and polluted environment of cities. Thirdly, the building boom of new apartment complex was a major driving force of changing urban spatial structure, but it could neither alleviate a residential gap between the poor and the rich areas nor a relief of traffic congestion. Finally, the urban policy in general was felt somewhat improved by citizens, but not in sectoral details.

  • EU is enlarging geographically by the process of expansion and is intensifying the economic bloc by the formation of European Union and European Monetary Union. This situation increases the direct investment in the intra-EU members and changes the intra-EU flows. First, EU is formed by the economic geographical space of the North and the South with a differentiation of economic factors and the degree of economic development. The North played a leading role for an augmentation of the intra-EU direct investment after the formation of EU. Second, the manufacturing industry of the intra-EU direct investment by industry was increased remarkably. In the intra-EU direct investment flow by region and industry, the South made relatively an outflow of the service industry and an inflow of the manufacturing industry. But the North made an outflow of the manufacturing industry and an inflow of the service industry. Third, in the intra-EU direct investment flows by manufacturing industry, the North concentrated in the petro-chemistry, metal-machinery and agro-food industry, however, the South which have relatively weak competitiveness compared to the North tends to show balanced investment patterns in all industries.
