최근 스캠 코인에 의한 피해 사례가 증가함에 따라 대부분의 가상자산 거래소가 상장된 가상자산에 대해 자체적 신뢰도 평가를 수행하고 있으나, 관련 법·제도적 체계의 부재로 인해 여전히 위험이 존재한다. 스캠 코인 여부를 판단하는 기존 서비스는 불명확한 스캠 코인 판별 기준으로 인해 충분히 신뢰하기 어려우며, 지도 학습에 필요한 라벨링 된 데이터셋이 충분하지 않아 관련 연구 또한 한계를 가진다. 본 논문은 클러스터링을 통해 스캠 코인 여부를 판단하는 것을 목표로 한다. 스캠 코인과 정상적인 가상자산을 구분하는 과정에서 유의미한 데이터를 수집하여 클러스터링을 수행하고, 스캠 코인 여부가 라벨링 된 테스트셋을 구성하여 클러스터링 결과를 평가한다. 이를 통해 본 논문이 제시하는 이더리움 기반 토큰에 대한 클러스터링 결과를 기반으로 추후 통일된 스캠 코인 판단 기준을 세울 수 있음을 제안한다.

Faced with the recent global economic recession, academics looked to the industrial B2B and B2C markets as potential new growth engines. In the B2B market, focusing on the relationship with customers, the relationship benefits are important, and institutional factors will affect the relationship and relationship values with customers. In this study, the relationship values between South Korea and Taiwan are compared by considering their national characteristics. By applying a mixed research method based on sequential exploratory design, 6 relationship values (supplier knowhow, service support, time to market, delivery performance, personal interaction, and product quality) are extracted. In particular, South Korea and Taiwan give priority to supplier knowhow and service support, respectively. Our research findings have both theoretical and practical implications for other emerging countries, as well as developed countries.

Infrastructure asset management can be defined as the long term and cost effective management strategy to meet the required service level. In most developed countries, the major motivations of the introduction of asset management are increment in number of assets, extension of maintenance field, accounting approaches of public facilities, performance-based FM(Facility Management), limitations of public funds and public-private partnership, life cycle cost approach, and the development of information technology. This paper discusses the strategic and stepwise methods of introducing infrastructure asset management. Strategic approaches are suggested to develop the practical methods of condition and value assessment of assets, and long-term capital investment plan for optimized decision making(ODM). Required systematic processes are analyzed in terms of resource and technical limitations and detailed implementation plan for each development phases are suggested.

As remote sensing technologies are evolving, and more satellites are orbited, the demand for using satellite data for disaster monitoring is rapidly increasing. Although natural and social disasters have been monitored using satellite data, constraints on establishing an integrated satellite-based near real-time disaster monitoring system have not been identified yet, and thus a novel framework for establishing such system remains to be presented. This research identifies constraints on establishing satellite data-based near real-time disaster monitoring systems by devising and testing a new conceptual framework of disaster monitoring, and then presents a feasible disaster monitoring system that relies mainly on acquirable satellite data. Implementing near real-time disaster monitoring by satellite remote sensing is constrained by technological and economic factors, and more significantly, it is also limited by interactions between organisations and policy that hamper timely acquiring appropriate satellite data for the purpose, and institutional factors that are related to satellite data analyses. Such constraints could be eased by employing an integrated computing platform, such as Amazon Web Services(AWS), which enables obtaining, storing and analysing satellite data, and by developing a toolkit by which appropriate satellites'sensors that are required for monitoring specific types of disaster, and their orbits, can be analysed. It is anticipated that the findings of this research could be used as meaningful reference when trying to establishing a satellite-based near real-time disaster monitoring system in any country.

These days, according as the role and function of science and technology become a important solving means of various national and social problems caused in knowledge information society as well as the development of national economy, the national target and mission of science and technology have been newly illuminated. The task of science and technology has embodied into national policies, and these policies acquired institutional foundation through the legal system related to science and technology. Recently, the discussions about the operating system of present science and technology legislation are often happened, if or not the legal system is optimal and appropriate itself under the changed environment. In special, some issues are raised continuously, for example, about the improvement of coordination system on S&T policies, and the governance system on national R&D programs, etc. This paper aims to research and suggest the reorganization method of science and technology law. For this purpose, the development and existing state of S&T legislation was investigated, the government role and policy driving direction were reviewed under the recent changed environment, and the problems of S&T law in structure and content were analyzed in variety of perspectives. On this basis, the reorganization methods of science and technology law are suggested.

Considering the role of roads in cities and the purpose of the Road Name Address Act, it is natural that the road name of the address is registered as the nearest road section adjacent to the building. Therefore, the Enforcement Decree of the Road Name Address Act also stipulates that mayor assign building numbers based on the basic numbers of road sections adjacent to the main entrances of buildings. However, there were cases where addresses are given from distant roads rather than adjacent roads among the actual road name addresses. Most of them are caused by misinterpretation of the case where the entrance faces more than one road. In this study, institutional and systematic improvement plans were proposed with the aim of enabling accurate selection of address information reference objects by demonstrating the limitations of the current building numbering method and presenting institutional improvement plans. Road name addresses were implemented for the core purpose of improving the inconvenience of locating the lot number address. Although some still complained of the inconvenience of road name addresses, successful settlement was possible because of the intuitive principle that most countries around the world could use it and find buildings along the road. Therefore, the system and system improvement should be made quickly in terms of accurate address information quality management and revitalization of related industries.

Ports have had a positive impact on urban development in the past, but they also have external diseconomies that reduce the competitiveness of port cities, such as damage to the residential environment. As a result, ports are also important policy targets for local governments. However, opportunities for participation by local governments are limited due to the centralized port policy structure and the lack of port capacity of local governments. Therefore, there is a growing interest in local port governance, which approaches the port as a target of local policy and seeks to solve it based on the participation and cooperation of various members such as local governments, general citizens, local businesses, and NGOs. The purpose of this study was to find the components for establishing local port governance and explore priorities by conducting AHP targeting experts and practitioners. As a result, in order to establish local port governance, it was confirmed that the establishment of an institutional foundation and a socio-cultural atmosphere is the top priority. More specifically, the interest and will of local governors, and local autonomy laws that are the institutional foundation to support the actual operation and the securing of the expertise of local government officials found to be of high priority.

As domestic construction investment has been gradually reduced, the issue of expanding overseas CM market has increased. Strengthening CM capability from the view point of project life-cycle is required in overseas CM market. However, current regulations institutionally force public CM services to focus on the construction phase. Therefore, Korean CM firms can hardly have the opportunities for accumulating technical competitiveness especially for pre-construction phase. Result of this study shows that the total efforts in terms of man-hours for the construction phase is found to be more than 78 percent in domestic public CM projects. In this context, this study proposes the policies and tasks for improving 'rigid man-hour placement', 'unreasonable CM fee standards', 'CM firm selection method', 'unreasonable business scope decision', and 'evaluation of owner's project management capability' in order to improve domestic CM Industry as well as to expand overseas CM market successfully.

Humanism connotes dignity and esteem with the essential idea of human and more human. This paper has conducted a inquiry of the understanding about human and humanism represented by visual image of film. Especially, this study investigated the way to adhere to reflective attitude about human and society. It is based on theoretical discussion of formalism and auteurism and analyzed the way of constructing time-space structure of (by Lars von Trier) which is known the typical formalism film. According to the findings, appeared to appropriate the ocularcentrism aesthetic to film form and give the self-regulation to definite the idea of film art through picturesque imagination of dramatic stage. Such a result means that it converts the filmic time-space to the virtual things and practicalize the classification of the ethical doctrine of innate goodness and innate sin of human and the definition of humanism. Also it means formalism film overturns the existing institutional mode of representation.

Under the 'Sustainability Paradigm', the building maintenance system is getting more important because more efficient maintenance means more sustainable building. This paper aims at improving present building maintenance system by comparing with the foreign developed countries' systems. The comparing countries are selected according to the level of building maintenance. As the results, 4 countries including USA, England, Germany, and Japan become the benchmark. The results show that building maintenance regulations are various by social, economic, and cultural characteristics. In addition, though building maintenance policy must be established, first of all, the related regulations and policy targets are prepared before the enforcement of maintenance regulation. The results provide some policy implications: 1. Building maintenance must be controled under the condition that a building can guarantee the safety of people and function of it. 2. Building maintenance system should contribute to the desirable urban environment and architectural culture.
