The technique of birdeye image generation of terrain through the use of satellite digital images and digital maps are very important elements and have applications in fanning establishment as well as the actual design of several construction works in complex fields. This paper studies stereo perspective image generation as a possibility through 3-dimensional analysis combined with digital elevation data and remotely sensed images. For this, first of all, ortho-images generated by very accurate GCP and DEM from contour file makes 3-dimensional terrain analysis possible and allows stereo­viewing at the highway construction planning sites. So, we developed the technical methods for the 3-dimensional approach on the planning sites of highways by use of perspective orthoimages. From this research, diverse terrain analysis is possible through stereo perspective image generation, and can leads to various application in road construction through gain study results from access to realtime virtual spatial on the objects area in korea.

Big data analysis refers the ability to store, manage and analyze collected data from an existing database management tool. In addition, extract value from large amounts of structured or unstructured data set and means the technology to analyze the results. Meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. Meta-analysis is sometimes expressed as an analysis of another analysis. Commonly, factors of metabolic syndrome can be defined as abdominal obesity, high triglycerides, low high density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose. This study will find meaningful mediator variables for criterion variables that affect before and after the metabolic syndrome studies, on the basis of the results of a meta-analysis. We reviewed a total of 5 studies related to metabolic syndrome published in Korea between 2000 and 2016, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study.

The essence of architecture is space acquired as a result of architect's design act, but the object of the design is not the space and it is the physical elements to construct it. The masters of modern architecture have described the types of spaces that can be composed of these elements, but there is a difficulty in constructing the space because they does not mention how to construct it. From this point of view, if architecture is the techniques for human behavior and the art of building space, it is recognized that there is a need for concrete research on how to construct a space with ambiguous substance. Therefore, I conducted research on the extensibility of diagonal spaces through '4 Logements Studio' by Henri Ciriani, a representative architect of Neo Corbusian. The 'network for identity' method proposed by Ciriani was examined as a methode to realize spatial expansion and the furniture should be designed as an element of reading space and 3 optimal alternatives for 4 housing arrangements were obtained based on the Equivalence, Lighting, View, and Community life.

A Meta-analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. Recently, the convergence of knowledge-based society and, information telecommunication technologies has a rapid impact on politics, economics and various fields. A meta-analysis was conducted to identify the relationships among satisfaction, trust, and loyalty in e-commerce studies. A total of 57 research papers published in Korean academic journals during 2002 and 2013 were reviewed and the causal relationships among satisfaction, trust, and loyalty in e-commerce were established. The result of the meta-analysis might be summarized that the highest effect size (r =. 591) was in the path from the satisfaction to the trust. The second biggest effect size (r =. 554) was found in the path between the satisfaction to the loyalty. The third biggest effect size (r =. 552) was found in the path between the trust to the loyalty. By the way, the smallest effect size (r =. 484) was found in the path between the trust to the satisfaction.

Big data analysis, in the large amount of data stored as the data warehouse which it refers the process of discovering meaningful new correlations, patterns, trends and creating new values. Thus, Big data analysis is an effective analysis of various big data that exist all over the world such as social big data, machine to machine (M2M) sensor data, and corporate customer relationship management data. In the big data era, it has become more important to effectively analyze not only structured data that is well organized in the database, but also unstructured big data such as the internet, social network services, and explosively generated web documents, e-mails, and social data in mobile environments. By the way, a meta analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. We reviewed a total of 750 samples among 50 studies published on the topic related as IDT between 2000 and 2017 in Korea.

핵융합에너지는 1930년대 한스 베테에 의해 태양과 별 에너지의 근원임이 밝혀진 후 소핵 폭탄실험 성공으로 그 위력적인 에너지를 인공적으로 만들 수 있음을 세상에 드러내게 된다. 그 뒤 이 에너지의 평화적인 이용 노력이 시작되었고 1958년 스위스에서 핵융합에너지의 평화적 이용에 대한 첫 국제회의가 열리게 되면서 에너지원으로서의 연구를 통해 냉전시대의 경쟁 대상의 과학기술의 하나로 부각되면서 눈부신 성능 향상을 보여주게 되었다. 아직 여러 어려운 관문이 남아있지만 기후변화와 에너지원 고갈에 의한 새로운 에너지원에 대한 강력한 필요성이 제기되면서 ITER와 같은 대형 국제공동연구시설 건설이 시작되었고 2030년대에는 최초의 핵융합발전소를 건설하려는 꿈도 그려가고 있다. 핵융합에너지를 얻는 방식에는 여러 방법이 시도되었는데 현재는 자기장을 이용해 플라즈마를 핵융합반응이 일어나기에 충분한 시간동안 가두는 자기핵융합방식과 관성으로 플라즈마를 가두는 관성핵융합방식으로 크게 구분할 수 있다. 자기핵융합방식의 경우 플라즈마를 만들고 가열하여 핵융합반응 확률이 높은 고온으로 가열하고 그 조건을 오래 지속시키는 기술들이 필요한데 이 기술들은 오늘날의 거의 모든 극한기술들이 망라되어 적용되는데 초전도, 고주파/ 초고주파, 대전력 공급, 대형 시설 실시간 제어기술, 대규모 신호처리기술, 고온 플라즈마 진단 기술, 대규모 시스템 시뮬레이션 기술 등이 그것이다. 여기에 또한 중요한 기술의 하나로 초고진공 기술이 필요하다. 이러한 기술이 집약되고 서로 통합되어 하나의 목적을 위해 쓰여지도록 고안되고 만들어진 장치가 자기핵융합 장치이며 따라서 현대의 자기핵융합장치들은 굉장히 복잡하며 대형 시설로 지어질 수밖에 없다. 우리나라는 1970년대 말부터 소형의 플라즈마 연구시설을 시작으로 자기핵융합 연구를 시작하면서 인력 양성을 시작하였으며 가속기 등 대형 연구시설이 본격적으로 지어지던 1990년대에 세계적으로 유래가 없는 초전도 자기핵융합장치인 KSTAR장치 건설 프로젝트를 시작하게 되었다. 총 11년이 넘는 건설기간 동안 여러 학교와 연구기관, 그리고 산업체가 참여하여 성공적으로 시운전을 실시하였으며 당당히 세계적인 장치를 통한 핵융합연구 대열에 동참하게 되었다. 이를 통한 기술 개발의 결과로 국제적 공동연구장치 ITER의 건설사업에 참여하게 되었고 KSTAR와 ITER를 통해 핵융합 에너지 상용화 기술 개발을 국가적인 기술개발의 목표로 결정하고 연구개발계획을 전략적으로 세워 진행하고 있다. 이번 논문에서는 자기핵융합의 특징과 연구 동향을 통해 우리나라의 기술 수준을 조망하고 특히 진공 기술 분야와의 상호 의존적 영향 분석을 통해 공동의 발전 방향을 모색해 보려고 한다.
