As public interests and demands on the library space and library goods increase, the role of librarians dealing with this issue has become more important. This research develops lists of core and non-core goods in space managements of public libraries, children's libraries, and school libraries. The lists will make the librarian's tasks effective and maximize user satisfaction. For public libraries, the space is divided into nine main areas, and a total of 80-90 goods(50-60 core and 20-30 non-core goods) are identified. The space of children's libraries is divided into four main areas(space for reading, books, entry, and special activities) with a list of 60-70 library goods(30 core and 30-40 non-core goods). School libraries consist of seven distinctive spaces, including spaces for books, multi-media, reading, and teaching, and it requires 90 goods in total(30-40 core and 50-60 non-core goods). The findings of this study can be utilized in listing up library goods. Further research should be conducted to develop such tools as guidelines, standards and manuals for space management.

The purpose of this study is to provide guidelines and recommendations on the process of planning and designing library space and it also reflects on developments which should be considered when planning new library space. The methodology of estimating library space needs of IFLA, a guide for public library building in New South Wales of Australia, and the recommendations for academic libraries in French were analysed. The results given throughout theses guidelines and recommendations are able to develop the guide for public library space in Korea. The guide suggested defines six broad types of library space; collection area, readers and library users, library staff, conference, meeting and cultural space, mechanical and support services, additional services areas. It is import to remember however that each library building and the service it provides is unique and should reflect the needs and aspiration of its community.

본 논문에서는 깊이 카메라로 받아들인 입력 영상의 3차원 공간 내에서 벽면을 분리하는 방법을 제안한다. 본 논문에서 제안하는 벽면이 구분된 영상은 벽면에 프로젝터를 투사하는 등의 3차원 공간 활용에 용이하다. 입력 영상에서의 좌표 점을 이용하여 법선 벡터를 검출하고, 법선 벡터를 통해 평면을 분리한다. 분리된 평면들을 실내 환경에서 알 수 있는 도메인 지식들에 기반하여 벽면으로 구분 된다.

This paper proposes a new re-coloring method for the people with the red-green color vision deficiency (CVD). These people have difficulty in discriminating the red and green colors since they abnormally perceive the hue and luminance value of the colors. We introduce a color transformation that adjusts the hue and luminance value in HSV color space. The color transformation is determined according to the severity of CVD. Our aim is to maintain the color differences in original image while maintaining the recolored image to be natural to the people with normal color vision. Experimental results show that the proposed method can yield more comprehensible images for the people with red-green CVD while maintaining the naturalness of the recolored images.

In this letter, we used PlanetScope imagery to conduct experiments on the color characteristics for oil type classification of marine oil spills through Red-Green-Blue (RGB) histogram analysis. The histograms of marine oil spills can be divided into three categories (dark black tones, light silver tones, and light rainbow tones) according to the distribution of pixel values in each band. Thick oil layers with dark black tones can be classified as heavy oil, while thin oil layers with light silver and rainbow tones can be classified as light oil. As more images are analyzed in the future, these oil spill detection and classification methods will become more generalized and reliable.

In this study, we separated the precipitation zones using the geographic location of stations and precipitation characteristics (monthly, seasonal, annual) in Gangwon province. Precipitation data of 66 weather stations (meterological office: 11 locations, auto weather system (AWS): 55 places) were used, and statistical method, K-means cluster method, was conducted for division of the precipitation regions. As the results of regional classification, the five zones of precipitation (Yongdong: 1 region, Youngseo: 4 regions) were separated. Seasonal average precipitation in spring is similar throughout Gangwon Province, seasonal average precipitation in summer has high values at Youngseo, and seasonal average precipitation in autumn and winter have high values at Youngdong. The some areas, the vicinity of Misiryeong and Daegwallyeong, happens the orographic precipitation in spatial analysis, but the orographic effects didn't occur for the whole Gangwon areas. However, to achieve more accurate results, the expansion of observatories per elevation and AWS data are demanded.

콘서트 홀과 같은 대형 공간의 경우와는 달리, 자동차 내의 작은 공간에서는 저주파의 음향 공진으로 인하여 상대적으로 높은 크로스오버 주파수까지 재생된 사운드가 컬러링 된다. 이러한 크로스오버 주파수는 Schroeder의 'large room limit'로 결정되며, 이것은 작은 공간과 대형 공간을 구분하게 되는 기준이 된다. 이러한 컬러링을 보상하기 위해, 먼저 대역 제한된 사인 스윕 신호를 이용하여 특정 차량의 저주파 응답 범위를 크로스오버 주파수까지 측정하였다. 본 논문에서는 이렇게 측정한 저주파 응답을 이퀄라이징하는 방법에 대하여 논의한다.

When the character of space could be dichotomized into the existing public space and private space, social order could be maintained by public policing only, Since enormous private property was formed and private space was enlarged by the development of capitalism, however, the necessity of private policing system came to the front. The large capitalists began to establish separate policing system to protect their property and safety. However, as social alteration was further diversified scale of economy was enlarged, the character of space could not be simply explained owing to the formation of space that could not be explained by simple dichotomous division. Namely, the 3rd space was formed as middle class between public space and private space. The 3rd space created additional demand of policing besides the existing public policing and private policing. The policing system to safety such demand of policing is called hybrid policing. As policing system in which character and legal status of public policing and private policing are mixed, the hybrid policing system may be originated from the diversification of demand of policing. Johnston insists that the demand of hybrid policing system will be further increased, becoming the model of policing system in the future. In Korea, the police guard system or special guard system can be classified into the type of hybrid policing. In accordance with the trend of diversified demand of policing in the future, I suggest to develop Korean model of hybrid policing system so that it can be utilized in elevating the policing index in Korean society.

관성 센서는 외부 장치의 도움 없이 3차원 공간상에서 움직임 측정이 가능하다. 최근 MEMS 기술의 발달로 소형 저가 관성 센서(가속도 센서 혹은 각속도 센서) 제작이 가능해져 관성 센서를 소형 휴대 기기에 내장하여 사용자의 움직임을 감지하거나 의도 파악하는 연구가 진행되고 있다. 본 연구에서는 관성 센서가 내장된 휴대 기기를 이용하여 3차원 공간상에서 6가지 위치에 따라서 각기 다른 6가지 소리를 발생하는 가상의 멀티 타악기 시스템을 제안한다. 즉, 휴대 기기를 상/하로 흔들면 가상 타악기의 타점 위치에 왔을 때 비트 음을 발생하고, 6개의 다른 위치를 구분하여 다른 타점의 위치에서 휴대 기기를 흔들면 각각 그 위치와 미리 지정된 소리가 발생하도록 하였다. 이러한 가상의 멀티 타악기 시스템을 위해서 3차원 공간상에서 실시간으로 사용자의 움직임을 감지하고 휴대 기기의 위치를 파악하는 것이 필요하다. 저가의 관성 센서를 이용하여 사용자가 휴대 기기를 움직이는 동작이 있는 상황에서 실시간으로 휴대 기기의 위치를 추정하는 것은 쉽지 않지만 본 연구에서는 다양한 사용자의 움직임 동작 분석을 통하여 사용자가 가상의 멀티 타악기를 상/하로 흔드는 동작을 감지하고 다른 위치로 이동하는 동작을 구분하였다. 개발된 동작 감지 알고리즘과 위치 구분 알고리즘을 휴대 기기에 적용되어 실제로 가상의 타악기 시스템을 구현하였다.
