The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc... But it is not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Second, the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I study the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which does not require any equations at all. The direct calibration procedure builds a lookup table(LUT) image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

Rural of Koreas has rapidly changed through the process of industrialization and urbanization. During past 30 years, development differences between urban and rural, metroplitan area and area derived from a highly economic growth, bring about dual specialization that deepens overpopulation and sparsity. Therefore, with a new concern about rural, necessity of rural development policy that developes a settlement and life area for settlement for ensuing stablized settlement and living activity of rural people, has been drived step by step. For rural welfare establishment that is settled and good hereafter, this study aims at attempting a theoretical approach about the way of development for rural settlement as a new rural development strategy through examination of today's rural reality, under assumption that rural people must be able to obtain stable jobs and to be pleasant without leaving rural area, and rural settlement to be able to enjoy urban advantages must be realized. Therefore, items that must be obtained basically rural area to be a human settlement space are equipment connected with a dwelling house, production, consumption, job relaxation, infrastructure connected with transportation or communication network and environment. By the way, the best function of a human settlement space makes a basic pleasant settlement area to be in the middle of that. Then rationalization of land use must be realized as being a best condition for human life around space of a dewelling house. Besides, spacial accessibility about all equipment of inhabitants must be easy. That is, economic distance, social distance and cultural distance as well as spacial distance must be included. Also, those spacial functions must be realized on a basis of suitable enironment for a human settlement life. At the same tiem, the upper area must be connected with the lower area as the system of spacial settlement in settlement space. But truely, as rural people can't satisfy with services of the surrounding rural areas, they desire better city or metroplitan. The these problems bring about inequality between urban and rural. Therefore, here are urgent reasons that must be done rearing of rural central town and rural integrated development of unit area. So, these dys, to correct maldistribution of land use and inequality of settlement space that Korean society faces on, new strategies of rural integrated development for lift area for settlement than gives the meaning. That rural areas become like a place for human settlement life will be able to be chosen in the view of humanism. The say of thinking of rural residents(Jukans-myun, Anseong-gun, Kyeonggi-do) was surveyed in order to develop new rural settlement planning. From the data collected in this survey, rural life-style, view on traditional rural life, agriculture, farming, agri-policy, social attitude, and degree of satifaction of rural life, etc, were analyzed. Firstly, most of rural residents interviewed in this survey have the opinion of not leaving their home village if living conditions improved to a reasonable level in the near future. In decision-making process of village affairs, they want to participate actively and equally. Secondly, in spite of their acceptance of agriculture as a vital sector destined to national security, most of them think that framing should be little of promise. Thirdly, they have the negative attitude to urban-oriented social valued and also to the agricultural policy, while seeking consolation through human and traditional viewing of rural life style. Therefore, in the development of new rural settlement model, idea-making should be directed to the betterment of communal value of village life, stability of rural economy, rationalization of rural life style and enhancement of rural-type happiness.

Studies on the variation state and the structural features of the Great tit's song due to geographical isolation were analyzed among Cheju-do, a geographically fully-isolated region and two inland areas far from being isolated each other. It was found that the variation coefficient of the Great tit's song was higher in the time factor of notes than in its frequency factor, irrespective of the geographical isolation. Each frequency factor of three areas was found to be remarkably correlative with its area, and to have a certain frequency range. After an analysis to measure the variation state among the above areas, it was found that whereas the voice features were common the great extent between Mt. Y□nwha and Mt. Y□hang, those in Cheju-do were considerably different from those in the other areas.

고분자전해질형 연료전지용 전극의 백금 이용률을 높이기 위해 촉매제조시 이온교환법을 이용하여 백금을 carbon에 담지하고 이에 따른 전지성능변화를 고찰하였다. 전극제조시 Nafion이 첨가되지 않은 경우 이온교환양이 증가함에 따라 전기화학적인 활성이 증가하여 전지성능이 증가하였다. 전극제조시 Nafion이 첨가된 경우, Nafion첨가량이 증가함에 따라 전지성능은 증가하였는 데 Nafin첨가에 의해 이온교환되지 않은 백금이 전기화학적인 활성을 가지게 되어 전지성능은 증가하였다. To improve platinum utilization of PEMFC(Proton exchange membrane fuel cell) electrode, in preparing catalytic powder, platinum was impregnated on carbon by ion exchange method and its cell performance was investigated. When electrode was prepared without adding Nafion solution, as Nafion pre-impregnated amount was increased, electrochemically active area and cell performance was increased. When electrode was prepared with Nafion solution, increase of adding Nafion amount was improvement of cell performance. By adding Nafion at preparation of electrode, non ion-exchange platinum was shown electrochemical activity, cell performance was improved.

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

이동식 저장매체로 대표되는 USB 저장장치는 클라우드 서비스가 일상화된 요즘에도 널리 사용되고 있다. 하지만 USB 저장장치에 은닉영역을 생성하여 악용하는 경우가 있기 때문에 안티 포렌식 관점에서도 이를 탐지하고 분석하는 연구가 필요하다. 본 논문에서는 은닉 파티션을 생성하고 이곳에 파일을 저장할 수 있어 안티 포렌식으로 악용될 수 있는 프로그램과 이것으로 만들어진 파일 시스템을 디지털 포렌식 관점에서 분석한다. USB storage devices, which are represented by removable storage media, are widely used even nowadays when cloud services are common. However, since they are cases where hidden areas are created and exploited in USB storage devices. This research is needed to detect and analyze them from an Anti-forensic point of view. In this paper, we analyze a program that can be exploited as Anti-forensic because it can create a hidden partition and store files there, and the file system created by it from a digital forensic point of view.

USB 메모리는 대표적인 이동식 저장 매체 중 하나이며 휴대성과 가용성이 용이하여 여러 분야에서 널리 사용되고 있다. 그러나 USB 메모리가 널리 사용되면서 악의적인 사용자가 USB 메모리에 데이터를 은닉하는 등의 안티포렌식 행위를 하여 디지털 포렌식 조사를 방해할 가능성이 있다. 본 논문에서는 저장매체의 파티션을 관리하는 프로그램인 Bootice에 숨겨진 영역을 생성하는 기능이 존재하여 악용할 경우 디지털 포렌식 조사를 방해할 가능성이 있기 때문에 이 영역을 분석하여 구조를 파악하고 은닉된 파티션을 탐지하는 방안을 제안한다. 또한 은닉 영역에 파일을 저장하고 디지털 포렌식 도구로부터 탐지를 회피하기 위한 방법을 제안한다. 이 연구는 은닉 영역을 생성하는 기능이 존재하는 Bootice 도구를 분석하여 안티포렌식 대응 방안과 안티포렌식 기법 발전에 기여한다. USB flash drive is one of the representative removable storage media and is widely used in various fields due to its ease of portability and availability. However, there is a possibility that malicious users may interfere with digital forensic investigation by performing anti-forensic actions such as hiding data in USB flash drive. In this paper, Bootice, a program that manages partitions of storage media, has a function of creating hidden areas, and if abused, it may interfere with digital forensic investigation, so we propose a plan to analyze this area to identify the structure and detect hidden partitions. It also proposes a method for storing files in hidden areas and avoiding detection from digital forensics tools. This study contributes to the development of anti-forensics countermeasures and anti-forensics techniques by analyzing Bootice tools that have the function of generating hidden areas.
