The amount of digital content grows exponentially by the development of the internet and the change of computing environments and the target also is getting wider. The industry using this digital content has been growing greatly. However, the distribution of pirated digital content is increasing using internet because digital content is easy to store and transmit and the damage is growing. In this paper, we propose safety trading system which can conceal the author's information safely in digital content in order to block illegal distribution of digital content. ARIA encryption algorithm is used to protect the concealed information of author in digital content and it is a help to track the illegal traders by doing fingerprinting of buyer information to digital content and managing the transaction information. The technical support for copyright dispute is to allow by providing the capability to verify illegal edit to original digital contents.

Since the unprecedented hydrogen fluoride leak accident in 2012, there has been growing demand for customized technical information for rapid response and chemical accident management agencies including the Ministry of Environment, the National Emergency Management Agency, and the National Police Agency need more information on chemicals and accident management. In this regard, this study aims to provide reliable technical data and guidelines to initial response agencies, similar to accident management technical reports of the US and Canada. In this study, we conducted a questionnaire survey and interviews on initial response agencies like fire stations, police stations, and local governments to identify new information items for appropriate initial response and improvements of current guidelines. We also collected and reviewed the Canada's TIPS, US EPA's hydrogen fluoride documents, domestic and foreign literature on applicability tests of control chemicals, and interview data, and then produced items to be listed in the technical guidelines. In addition, to establish database of on-site technical information, we carried out applicability tests for accident control data including ① emergency shut down devide, safety guard, shut down valve, ground connection, dyke, transfer pipe, scrubber, and sensor; ② literature and field survey on distribution type and transportation/storage characteristics (container identification, valve, ground connection, etc.); ③ classification and identification of storage/transportation facilities and emergency management methodslike leak prevention, chemicals control, and cutoff or bypass of rain drainage; ④ domestic/foreign analysis methods and environmental standards including portable detection methods, test standards, and exposure limits; and ⑤ comparison/evaluation of neutralization efficiency of control chemicals on toxic substances.

Korean government has created the organizations for the private research development, has increased the support in taxes and funds, and has promoted the simplification of administrative structure and the removal of unnecessary restriction for the settlement of the private enterprise-centered technical reformation system. The investment of the research and development of Korea was 2.17% of GNP and the number of researchers was 89,000 in 1992. Korean government will expand the investment of research and development by 3-4% of GNP until 1998 and reinforce the number of researchers by 140,000. For the timely supply of the technical information, which is expected to be a major industry base in the year 2000, Korean government has already started to invest and continuously increased key projects which are focused on the database architectures, information distribution systems, and organizations for the information dissemination.

AI-powered robot news is drawing attention as artificial intelligence technology is fully spread in the news distribution field. Robot news still has many technical and ethical problems, but academic research on this is insufficient. This study analyzes the issue of robot writing in artificial intelligent based robot journalism industry using SWOT analysis. As a result, the advantages of big data processes, accurate information gathering, high efficiency and disadvantages such as lack of independent arguments and lack of evidence and opportunities for technical development, government support, academic development, and industrial applications, and threats such as uncritical acceptance and lack of talent have been found. This study suggests three future-oriented directions, such as human-machine collaboration, intelligent news, and chat-bot, through previous studies on the development direction of robot journalism-based article writing.

본 연구에서는 동기 구동형 이동 로봇의 제어를 위한 운동 방정식, 주어진 지도 내의 목표 지점으로의 최적 경로 생성과 경로 추적을 위한 경로 계획, 그리고 이동 로봇의 위치를 측정하기 위한 균등 군집 몬테카를로 위치 측정 기법을 제안하였다. 이동 로봇의 위치 측정 실험을 통해 총 73회 반복된 위치 측정에서 기존의 몬테카를로 위치 측정의 평균 수행 속도가 12.8ms로 측정된 반면, 균등 군집 관리 몬테카를로 위치 측정의 평균 수행 속도는 9.3ms로 측정되었다. 또한 기존의 몬테카를로 위치 측정 기법이 위치 측정에 실패하는 동일 환경에서 균등 군집 몬테카를로 기법은 올바른 일치 측정의 결과를 보임을 확인하였다.

Recently genuine products and good commerce have been threatened by distributing forgery in home and abroad markets. It is because most customers cannot distinguish whether genuine or forgery, so establishing of strict distribution system is needed. Therefore recently Genuine Guarantee System which can confirm genuine products has been developed using the Internet. The object of this system is protecting to purchase forgery by confirming distribution system. This system can provide a reliable environment of consumption. But to be diffused at distribution structure and applied, We require the understanding about not only technical side but behavior side. That is, we need to research the cause and process of using this new information system. in this research, we understand the cause of affection on the system's acceptance and define the suitability about the model according to Technology Acceptance Model by Davis. The above can build the suitable operating strategy and understand the criterion as a new business model.

To develope SOC(social overhead capita) which constructs the railroad, highway etc., the geo-technical foundation have to be well understood for the safety works. In this paper, we selected Moonkyung area for the study area, which has various geological units and geological structure including the big thrust and fold. By this reason one of the geo-technical information is the engineering geology map. To make the map, lithology and soil distribution with drilling data are important elements. Three dimensional geo-infomation is established by fence diagram which is several geological cross sections and/or computer software 3D Geomodeller, EarthVision, GSI3D, Gocad.

Base on the development of mobile communication, the future mobile communication systems were expected to provide higher quality of multimedia services for users than today's systems. Therefore, many technical factors are needed in this systems. Especially these secrecy and the safety would be obtained through the introduction of the security for mobile communication. In this paper, we presents weaknesses and propose required properties in mobile communication. Based on those proposed properties, we propose a new 'call set-up' and 'hand-off' protocol for authentication and key distribution. Also we compare between the proposed scheme and conventional schemes.
