This study has seen about a indemnity system of fishery damage by natural disasters such as a problem and improvement methods of government aid system and system on accident insurance for cultured fishery products. Recently, in the situation that the demage of aquaculture industry caused by frequent typhoon resulted from global warming and abnormal changed of weather is nasty, the accident insurance for cultured fishery products is necessary to show its true quality and to protect fishers against natural disasters owing to the limitation of government's aid for them. However, The objects of accident insurance for cultured fishery products which is progress on, is too short to apply, so that it is absolutely insufficient to fulfill the demands of culturing fishermen. Therefore, It could be a certain preparation to magnify the range of object items of it and to convert the trial industry being adjusted to limited area into full scale industry to adjust over all nationally. Furthermore, This insurance is complicated and strict to join rather than other insurances. As it can be seen by examples that got in trouble, despite culturing fishermen applied to join the insurance, they took all demage because the insurance was not realized. So, It is hard to say that causes impute the responsibility of it to the authority of insurance, not culturing fishery. They should simplify the registration process, limit the period each registration process and consider a countermeasure to complete it. Concerning compensation for the loss, agriculture part is easier to investigate the loss due to remained dead crop damaged by natural disaster, meanwhile, in fishing part, especially in case of cultivation of fish, it is difficult to investigate the loss and demage because crops are blown all together with typhoon when it comes plus the facilities of them are also very old. Consequently to solve the problem needs more positive attitude as it is policy insurance.

As modern society changes toward knowledge based society, the patent policy and professional manpower need to be changed because interest and importance about patent, trademarks, intellectual property right and copyright of business secret are increasing. In order to facilitate trading of the technology developed in the private sector and to promote the business, the Act of technology transfer and commercialization promotion is prepared. In the law, the article 14 says that who have expertise on commercialization of the technology transfer can be registered as a technology trader to the Minister of Knowledge Economy. For the purpose of finding improvements of the technology trader's registration system, comparison method was studied. Technology trader compare with licensed real estate agent which is similar with it in terms of trade. There are several results from this study by followings. The unique tasks of technology traders should be specified for increasing authority of technology transfer expert. Manual criteria of post management should be prepared through registration certificate management agency which operated by charging. In addition, The announcement document should be prepared carefully for necessity of announcement and registration criteria of technology trading business. These improvements are enable to motivate trading market and impact to expand the base of technology marketing and technology transfer-commercialization.

Currently, the legal framework for installation of safety facilities has not been implemented for new multi-purpose business excluding 23 multi-purpose business types, and therefore, there is a high likelihood of large number of casualties in case of fire accident. At present, the new multi-purpose business can start its operation only with administrative actions of the licensing agencies and registration to the tax agency, and it is difficult that the fire department, which is a competent safety management department, makes intervention them in the same way as before. In addition, as the licensing agency has no authority to restrict the business due to insufficient implementation of safety facilities, a lot of civil complaints occur, which causes difficulties in changing concerned laws and regulations rapidly. In this study, it is considered to analyze the legal system, status of safety management of multi-purpose business, type of new multi-use facility and characteristics of fire risk. Based on such analysis results, this study will suggest the improvement plan to solve the blind zones in the safety management, which enables the multi-purpose business to be operated within the legal framework.

The purpose of this study is to suggest public roles and responsibilities about Architecture Heritage under Act on Value Enhancement of Hanok and Other Architecture Asset by analyzing the Architecture Heritage System of Spain. The case study on Spain, Catalonia, Barcelona's Act of architectural heritage was conducted to analyze the laws and guidelines related to Architectural Heritage and to confirm the perspective on Architectural Heritage and roles by subjects through interviews with the department in charge. The role of the central governments is to the responsibility of preservation that can be offset by create incentives and expand programs to create consensus among citizens. The architecture asset survey, which is the responsibility of the municipal governments, should increase confidence by the detailed survey to define the authority and role of the basic local government. And the municipal governments must increase the architectural heritage more support and incentive. Excellence architectural assets must diversify the range of incentive and preservation, and ask for registration that various subjects can apply it by expanding category of application to public sector, non-governmental organization, citizens rather than an owner.

VANET(Vehicle Ad-hoc Network) 환경은 도로위의 차량을 노드로 하여 구성하는 애드혹 네트워크로써 최근 들어 그 연구가 활발히 진행되고 있는 분야이다. 일반적인 애드혹 환경과 마찬가지로 VANET 환경에서도 보안적인 문제가 중요한 이슈로 대두되고 있다. VANET 환경에서 가장 중요하게 요구되는 보안요소는 차량의 익명성을 통한 위치 프라이버시와 협력 운전(cooperative driving) 단계에서 사용되는 메시지에 대한 인증, 무결성, 부인방지 등이다. 본 논문에서는 익명 아이디(pseudonym), 그룹화 등을 통해 차량의 위치 프라이버시를 제공하고 또한 이를 이용해 VANET 환경에서 사용할 수 있는 라우팅 프로토콜을 제안하고자 한다. RA(Registration Authority)에서 발급되는 익명 아이디의 집합과 차량의 전송 범위를 고려해서 구성되는 그룹화는 그룹에 속한 차량에 대해 익명성을 제공하고, 또한 그룹리더에 의해 생성되는 그룹키를 통해 효율적인 협력 운전 메시지 전달을 할 수 있게 된다. 그리고 각각의 그룹리더를 라우터로 이용해 전달되는 라우팅 프로토콜은 노드가 매우 유동적으로 움직이는 VANET 환경에서 효과적으로 메시지를 전달할 수 있도록 해줄 것이다.

One of the major causes of serious air pollution worldwide is emissions from road transportation. A number of countries are working to reduce vehicle emissions, and the Seoul Metropolitan Government is also implementing active policies to reduce emissions by setting a target of 40% by 2030. Implementing these policies requires the introduction of practical indicators. Most of the domestic emissions are calculated by the emission coefficient, a function of speed at the National Institute of Environmental Research under the Ministry of Environment, but the dynamic variable speed is limited to being used as an indicator of the number of eco-friendly vehicles. Therefore, this study calculated the emission rates in Seoul using the vehicle registration data of Seoul and the vehicle inspection data from the Korea Transportation Safety Authority. The tendency of emissions was determined according to key variables such as vehicle type, fuel and mileage. Emissions were based on carbon monoxide, hydrocarbons, nitrogen oxides and particulate matter measured by vehicle inspection from the Korea Transportation Safety Authority. As a result, the emission rates showed a significant trend according to the model year and mileage. This can be used as a policy indicator to preferentially switch commercial vehicles with old model years and long mileage when switching eco-friendly vehicles in Seoul.

Struggles to gain acknowledgement of identity have a characteristic of movement to recover human dignity. Participants in this movement come to confirm themselves as the subject of rights and communicate one another, free from oppression. Being guaranteed the opportunity to participate in the public opinion formation process is an indispensable element of human rights. In 1980, though it was short and incomplete, Gwangju experienced communal autonomy under the condition that state power was temporarily stopped. The contents and memories of the Gwangju Democratization Movement that intended to protect autonomy of civil society, resisting pillage of state power, remain intact in the 1980 Archives for the May 18th. The 5.18 archives were registered in UNESCO's Memory of the World in 2011, with its value of human rights and protection of democracy being acknowledged. The 5.18 archives have memories of resistance and struggles for justice, and sacrifices and pains of citizens under oppressive political authority in Gwangju, 1980. Thus, these archives are related to the historical struggles for democracy, and suggest a lesson on the transition process towards democracy to us. Preservation and utilization of the documentary heritage constantly lead the memories of historical events to the present, and enable exchanges of experiences and ideas between the present and the future. This study, through the process of UNESCO's Memory of the World registration and post-registration process, beyond the value of archives, tries to examine how historical events are led to the present, through the archives and to discuss the other values of archives.

Autonomous driving technology is shaping the future of personalized travel, encouraging personalized travel, and traffic impact could be influenced by individualized travel behavior during the transition of driving entity from human to machine. In order to evaluate traffic impact, it is necessary to estimate the total number of trips based on an understanding of individual travel characteristics. The Activity-based model(ABM), which allows for the reflection of individual travel characteristics, deals with all travel sequences of an individual. Understanding the relationship between travel and travel must be important for assessing traffic impact using ABM. However, the ABM has a limitation in the data hunger model. It is difficult to adjust in the actual demand forecasting. Therefore, we utilized a Tour-based model that can explain the relationship between travels based on household travel survey data instead. After that, vehicle registration and population data were used for correction. The result showed that, compared to the KTDB one, the traffic generation exhibited a 13% increase in total trips and approximately 9% reduction in working trips, valid within an acceptable margin of error. As a result, it can be used as a generation correction method based on Tour, which can reflect individual travel characteristics, prior to building an activity-based model to predict demand due to the introduction of autonomous vehicles in terms of road operation, which is the ultimate goal of this study.

This study was designed to verify reliability and feasibility by analyzing elderly drivers' ability test tools for older drivers aged 65 or older, which were improved in 2018 and are currently being conducted by the Korea Highway Traffic Authority. Only those aged 65 or older who voluntarily applied to the elderly driving ability evaluation system implemented by the Seoul branch of the Korea Highway Traffic Authority. The research was conducted for about 50 days until Aug. 31, 2018, starting with the registration and inspection of the first study subjects. The analysis performed a correlation analysis with existing tools and cognitive testing tools (MMSE_K) to determine their feasibility and reliability as an improved tool in 2018. As a result, the first, the speed distance, time-space memory, and dispersionism of each sub-component of the old version showed statistically significant static correlation with the sub-factor of the current version. Persistence, on the other hand, was not statistically significant to the current version. The limitations of this study were as follows. Most of the people in the study were highly educated and residents in the metropolitan area. Therefore, it is likely that the results of MSE_K, which checks cognitive and judgment skills, have been upgraded. Also, cognitive tools that are measured by computers are likely to have real measurement errors for generations who are not familiar with computers. Therefore, it is expected that improvement and development of tools for improving the limit points at the site and assessing actual operation capability will be required.
