The purpose of this study is to examine the policy direction and execution plans of the Japanese central and local governments for the use of vacant houses after the enactment of the "Special Act on Vacant Houses." It also seeks to provide suggestions for establishing vacant house policies in Korea by identifying the characteristics of the Japanese policies, and to suggest policy alternatives that can contribute to environmental improvement and regional revitalization through the use of vacant houses. For this purpose, we examined Japan's "Special Act on Vacant Houses," the process of establishing vacant house policies in the Japanese central and local governments, and the contents and direction of these policies. Below are the results of this study. First, the Japanese government revised mid to long-term policies related to housing after the enactment of the "Special Act on Vacant Houses", thereby providing ground for local governments to establish vacant house policies. Second, the government actively supported the operation and funding of related associations so that the private sector rather than the public sector could address vacant house problems. Third, the government subsidized administrative expenses such as cost of finding vacant house owners to prevent neglect of vacant houses, and showed its will to address vacant house problems by revising taxes such as property taxes and transfer income taxes. Fourth, the government has enacted distinct ordinances for each local government and made it possible to perform customized policies such as allowing residents and local stakeholders to participate in the establishment of vacant house policies. Fifth, the government made it possible to manage vacant houses efficiently by allowing the vacant house bank to provide all information related to the use of vacant houses. It is necessary for Korea's central and local governments to refer to these precedent cases and create efforts to reduce trial and error when establishing vacant house policies.

As Korea is predicted to be a super-aged society in the near future, transport policies that internalize the elderly have also drawn attentions. Even though some studies have examined the travel by the elderly with various motives, it is, however, difficult to find references that deal with the unique spatio-temporal characteristics of senior trips. For example, the models by time period have represented the temporal property while a set of independent variables associated with urban infrastructure have addressed the spatial feature. This study was conducted under a trip attraction model for transit. The result shows that transit facilities, commercial areas, and hospitals are the dominant factors to explain the travel by the elderly, particularly during 09:00-17:00.

If an accident occurs at work places that handle 'the accident preparedness substances', it causes more property damage and casualties than accidents of normal chemical substances. Even though various systems and regulations have been operated in order to prevent accidents, techniques for reducing and removing human error, which is one of the main reasons of accidents, are still inadequate. In this paper, hazardous work digitization, potential hazard verification, and work evaluation based on domestic technical guidelines have been performed through a case study of the accident of hydrofluoric acid leakage in Gumi in September 2012, and development of a new risk mapping method has been studied to supplement existing systems.

Innovation, esp. technological innovation, in service sectors has drawn much attention as innovation-driven economy and service-led growth has been emphasized in the 21st century. This paper attempts to analyze the technological innovation from the perspective of geography and to understand the role of cooperative networks in the technological innovation. In sum, this study reveals that more firms in the Seoul Metropolitan Area (SMA) tended to succeed in the technological innovation in service sectors than those in the provinces. However, the difference originated from the difference in firms' internal capabilities, not from the difference in the external innovative capabilities represented by cooperative networks relevant to innovative milieu. In terms of cooperative partners, the fm in the provinces placed special importance on universities as cooperative partners, while the firms in the SMA put much emphasis on various types of cooperative partners. The cooperation with private partners was a statistically meaningful variable for the occurrence of technological innovation, regardless of firms' location. The cooperation with public partners proved to influence firms' application for the intellectual property right such as patents in both the SMA and the provinces.

Despite the recent economic difficulties, the on-line market is overtaking the off-line market. Since US Amazon CEO Jeff Bezos mentioned that a delivery service using drones is possible, it has been creating new perspectives and values that have never been seen before. Drones are being used in various fields. Among them, the delivery service using drones will be the future growth engine of Korea in cooperation with the 4th industrial revolution. However, as drones are put into practical use, problems such as human life and property damage and personal information protection due to public collisions or falls are expected. The practical use of future drones is inevitable, not optional. As a method for commercialization of drones, first, securing safety through drone use and securing a national certification system, which is the minimum standard system for drone safety, and second, securing various infrastructures by activating drone use, and third, aviation regulations and personal information protection, etc. It needs to be supplemented in terms of laws and regulations.

According to the statistics released by Ministry of Public Safety and Security, the number of restaurant fires in Korea reached around 2,400 and 169 damages of human life and damages to property was approximately over $8.8 billion for recent 3 years. It could be desirable having automatic commercial fire-extinguishing equipment at commercial facilities excluding housing facilities for the safety, applying at the place first where it has been more risky and expected fire can be occurred relatively because economical burden can be accelerated. In order to do this, adjust its level to meet the same level of the kitchen for 'Specific Target for Fire Fighting' that "gas leak alarm" has be equipped relevant regulations and it is considered and reasonable to expand the limit of application gradually.

Fire stations should be located in optimal location to act quickly in case of emergency and minimize damages as a public facility that protects life and property of local residents. Siting fire stations without regard for the accessibility and occurrence factors of an accident may provide fire service unequally. Therefore service analysis is necessary to reduce the blind spot of disaster and safety and to offer equal fire-service at this time. Especially fire stations can service more efficiently than before by reducing a more likely vulnerable area. This study suggests methods of mapping index of value that represents vulnerability of the occurrence of an accident and extracting service zone map of fire stations, as an initial research for offering efficient fire service. Geographical distribution mismatch between service zone map and vulnerability map is figured out and vulnerable area for fire service is defined by using map overlay method.

In each country, the periodic ISI(In-Service Inspection) is required by the law to protect the public health and property from the potential accident of the nuclear facilities. To support the implementation of ISI program, the prescriptive ISI technical standards have been established. As the key parts of the ISI program, the non-destructive examination techniques are widely used to identify the degree of degradation of the pressure boundary components and welds. Recently, the risk informed-ISI program has been developed and implemented in several countries. Nonetheless, the existing ISI program which prescriptively decides the scope of inspection still has its own significance. In this article, the technical standards of ISI in leading countries like US, france, Canada, and Japan are reviewed and compared with the safety guide by IAEA. An outline to revise the domestic technical standards of ISI has been suggested.

This study develops a day-to-day dynamics modeling framework, incorporating a consistent drivers' travel time perception behavior and traffic information provision. Descriptive traffic information is updated and provided to the subscribers making a final decision on route choice. Nonsubscribers(not equipped any information devices) are assumed to obtain daily traffic information from their experience or friends or other public agencies. Drivers' route choice behavior is modeled based on boundedly-rational behavior rules. A microscopic traffic simulation model is adopted to evaluate the network system performance. Numerical experiments on a real world network have demonstrated the convergent property of the proposed model and the effectiveness of the consistent perception model.

Recently, there has been an increasing number of cases in which important data (personal information, technology, etc.) of national and public institutions are leaked to the outside world. Surveys show that the largest cause of such leakage accidents is "insiders." Insiders of organization with the most authority can cause more damage than technology leaks caused by external attacks due to the organization. This is due to the characteristics of insiders who have relatively easy access to the organization's major assets. This study aims to present an optimized property selection model for detecting such abnormalities through supervised learning algorithms among machine learning techniques using actual data such as CrossNet data transfer system transmission log, e-mail transmission log, and personnel information, which safely transmits data between separate areas (security area and non-security area) of the business network and the Internet network.
