We tried to analyze qualitatively a total of 110 the research papers which were related domestic ecological restoration technologies about 15 years through semantic network analysis in social network analysis. In order to understand the research trends of ecological restoration technologies, we analyzed the degree centrality and betweenness centrality of the Stream/Wetland, Slope, Soil/Others fields selected as Word Cloud. As a result, ecological restoration technologies have been changed. They were focused on the restoration of species or their habitats in the past. However, they have been evolved into the detailed systems to respond in unpredictable natural disasters and climate change, high-resolution image implementation technology to accurately grasp the practical environment and methods related to environmental restoration for human in urban ecosystem. In the future, investment and technology for the ecosystem restoration field will be continuously demanded for the symbiosis of human beings and species in the damaged ecosystem. Therefore, the research trend of ecological restoration technologies should be provided as reliable guidelines when decision makers establish the policy direction or when researchers select their subjects.

전기차 수요의 증가로 향후 폐차 혹은 배터리 노후화로 인한 폐배터리 배출량 급증이 예상됨에 따라 이에 대한 적정 관리가 시급한 실정이다. 기술개발 측면에서는 데이터 기반 진단 등 다양한 폐배터리 진단 및 관리 기술이 주목을 받고 있다. 또한 로봇기반 자동 해체 기술은 산업 현장에서의 Test 검증 및 향후 배터리 관련 데이터베이스와의 연동이 필요한 것으로 보인다. 특히 향후 폐배터리 순환과정에서의 효율화와 동시에 안전성/친환경성 제고를 위한 다양하고 선진적인 배터리 진단 및 평가기법 개발 및 보급이 중요하다. 또한 리튬 관련 화학물질 배출이동에 대한 데이터베이스화와 배터리 연소시 가스유출위험 및 소방안전에 관한 평가 및 대처가 중요할 것으로 보인다. 더 나아가 데이터 기반 진단/분류/해체 과정을 재활용/최종폐기와 연계된 다양한 관점에서의 폐배터리 전주기 관리 최적화 등에 향후 더 많은 연구개발이 필요하다고 판단된다. 그리고 일련의 데이터는 차후 배터리 생산 시 환경적 부담을 감소시키고 재이용/재활용이 원활하도록 청정설계 및 제조에 기여해야 한다. 또한 이러한 최적화는 전기차 배터리의 향후 기술 및 시장 변동을 감안하여 추진되어야 한다.

최근 들어, 수많은 기업들은 IT 분야에서의 비용절감을 위하여 클라우드 솔루션을 채택해 오고 있다. 한편 디지털 흔적이 추후 법정에서 온전한 디지털 증거로 인정받기 위해서는 증거능력이 있어야 하는데, 그 중에서도 무결성은 증거능력을 갖추기 위한 여러 요건 중 하나이다. 이와 같은 맥락에서, 본 논문에서는 대표적인 사설 클라우드 솔루션(Citrix, VMware, MS Hyper-V)으로부터 수집된 VM 데이터를 대상으로 무결성 검증실험을 수행 하였으며, 그 결과로서 사설 클라우드 컴퓨팅 환경에서 수집된 VM 데이터에 대한 무결성 검증방법을 제안하고자 한다. 또한, 전 세계적으로 널리 사용되는 Guidance사의 EnCase 도구가 대표적인 가상 디스크 파일인 VHD (Virtual Hard Disk) 파일을 제대로 마운트 하지 못하는 오류가 있음을 확인하였다.

The purpose of this study is to suggest a strategy of creating sustainable city's streets by extracting a elements related the task related with society, economic, and environment. The method of this study is as follows. First step, we extract main task for developing sustainable settlements through studying literature review. Second step, based on the task for sustainable settlements, we generate various elements for developing sustainable street environments. Third step, we carry out a survey targeting experts related to field of urban environment. Fourth step, we analyze their priority about developing elements and the difference between groups. Last step, through correlation analysis between three task and elements for developing sustainable streets, we discuss the specific application around developing elements. The result of this study is as follows. Firstly, from a social point of view, the task related to connecting of historical and cultural characteristic is the most important thing. In a environmental view, it illustrates that application of technologies based on IT is more important than use of sustainable land. In a economic paint of view, it presents that the elements of city security & disasters are important.

본 연구는 텍스트 마이닝 기법을 활용하여 환경 분야에서 ICT의 활용 연구동향을 정량적으로 분석하였다. 이를 위해 환경 분야 키워드 38개, ICT 관련 키워드 16개를 바탕으로 국가과학기술정보센터(NDSL)에서 최근 20년(1996년-2015년)의 논문 359편을 수집하였다. 해당 논문을 대상으로 환경 분야 및 ICT 관련 자연어를 처리하여 말뭉치(Corpus)단위로 분류체계를 재구성하였다. 전술된 분류체계의 키워드를 바탕으로 텍스트 마이닝 분석 기법인 빈도 분석, 키워드 분석, 키워드 간 연관규칙을 확인하였다. 그 결과 '환경 일반' 및 '기후' 분야의 키워드 출현 빈도가 전체의 77 %, ICT는 '공공융합서비스' 및 '산업융합서비스'가 약 30 %의 비율을 차지하였다. 시계열 분석을 통해 환경 분야에서의 ICT 활용 연구는 최근 5년(2011년-2015년)사이에 급증하여 과거(1996년-2010년)과 비교하여 약 2배 이상 관련 연구가 증가된 것으로 나타났다. 키워드 간 연관 규칙을 생성하여 환경 분야를 기준으로 나타내었을 때, '환경 일반'은 16개, '기후'는 '14'개의 ICT 기반 기술을 주로 활용하고 있는 것으로 확인하였다.

This study investigates the factors that affect the adoption of object orientation . One major research question is addressed : What are the factors that significantly influeence the adoption of object orientation ? This study especially explores the impact of independent variables on the level of actual usage of object orientation. The independent variables are classified into four categories as follow ; (1) Individual factors : amount of experience in using the structures methods and level of openness toward new technologies ; (2) Managerical factors : perceived management support and training : (3) Organizatinal factors : number of IS professionals in the working group and that in organization ; and (4) Environmental factors ; accessibility to technology champions and software hardware environment supporting object orientation. A Questionnaire measuring the above variables was utilized to investigate the effect of these variables on the dependent variable, the actual usage of object orientation. The structured questionnaire was administered to Data Processing Management Association (DPMA) professionals in U. S. The results of this study revealed several important findings with most results being consistent with expectations based on related theory. The personal openness toward new technologies, perceived management support, training, and hardware/software environment were highly related to the usage of object orientation. This study suggested an empiriclal basis for understanding the early adoption of object orientation in organization.

Recently, virtual reality technologies have been rapidly developed and realtime virtual simulation methods have been extensively employed for several application areas such as game, sports, manufacturing, military, and so on. A 3D database in realtime virtual simulation plays a key role because it makes users feel reality in virtual space. In a application view of 3D database, a systematic construction approach is required to reduce its construction time and increase its quality. However, many researches have been mostly focused on realtime graphic issues and its key technologies. In virtual simulation of transportation equipments, this paper proposes a systematic construction process of 3D database consisting of four stages as follows: 1) determine the activity space of a equipment, 2) collect data related to 3D database construction, 3) make a 3-dimensional modeling strategy, and 4) generate and evaluate a 3D model. This paper also introduces a new procedure of 3D environment modeling, which summarizes and expands our modeling experiences, to be used as a modeling guide.

Overall studies for the N-nitrosodimethylamine (NDMA) formation and treatment methods were conducted. In this study, occurrence in several countries and emerging treatment technologies of NDMA were generally reviewed. The NDMA formation was dependent on pH, contact time, and molar ratio (monochloramine/dimethylamine). The formation was rapidly increased when the molar ratio was greater than 1. It was likely that monochloramine could be related to stimulate NDMA formation. NDMA concentrations in water supply and wastewater plants after disinfection were approximately 10 ng/L and 100 ng/L, respectively. UV oxidation and adsorption processes are regarded as effective technologies for the NDMA removal. It is suggested that the UV oxidation with proper lamps is applied in water supply system.

Many changes in the railway environment has directly affected to the railway company. To cope immediately with the influence of environment and to promote productivity, the railway company has to introduce an efficient train operation system and related core technologies. The railway system is composed or large-scale infrastructures ann high-cost trains. Simulation method is one or core technologies and also is efficient tool for planning and analyzing this kind of complex system. The purpose of this research is to develop multi-train traffic simulator considering high-speed train for GyongBu-Line. To achieve this objective, the elements of railway system was analyzed, and as a result, a data structure modeling for the railway system such as rail-Tine infrastructure, rain, timetable and operational route is presented. The developed simulator is composed of three major part : input-module, main-module, and output module. The concept and brief explanation of each module will be treated.
