Recently, medical accidents related to surgical procedures have increased. In addition, the media reported that some of these accidents were involved in health crimes. Patient-advocate groups have called for mandatory establishment and management of CCTV in operating rooms. There is a lot of discussion among the interested parties, so it is necessary to review the relevant laws and regulations. The purpose of this study is to identify the characteristics of CCTV in operating rooms and to review legislations related to establishment and management of the CCTV in operating rooms. Medical institutions use CCTV for management of facilities and patient safety and install it in operating rooms optionally. The Constitution guarantees the privacy and the privacy of correspondence of every citizen, but it can be limited by the law for public welfare. Currently, however, there is no existing law about establishment and management of the CCTV in operating rooms and it can be defect of legal system. Under the current legislations, it is likely that the Self-determination can be violated due to the characteristic of healthcare provider when CCTV is mandatorily installed in operating room. In addition, the regulations on access and leakage of confidential information known by operator are insufficient. So that, the safety of the visual data might be threatened. Furthermore, unless the period and the place of storage of the visual data are clearly defined, it is highly unlikely to meet the original purpose of patient safety and prevention of medical accidents. This study is meaningful as there is few previous study on this topic although the need for legal review about this is growing and several bills are being proposed. It is expected that the results of this study can be utilized as basic data for enactment or amendment of the laws and regulations about establishment and management of CCTV in operating rooms.

국내의 건축물에 관한 통계정보는 국토해양부에 의해서 공표된 통계연보로서 2002년부터 매년마다 제공되고 있다.(국토해양통계누리, https : //stat.mltm.go.kr/potal/stat/yearReport.do) 건축물의 통계연보는 과거부터 2002년까지 매 3년마다 공표된 것으로 알려지고 있다. 이 통계연보에는 건축물 현황과 건축허가착공 통계가 수록되어 있다. 건축물 현황에는 2009년 말을 기준으로 기존 건축물이 전체 6,618,131동으로서 용도별, 층수와 연면적별 그리고 소유구분별 등의 구분에 따라 건축물의 동수에 관한 통계자료가 포함돼 있다. 건축허가 및 착공통계에는 용도별과 구조재료별의 분류에 따라 건축물의 동수에 관한 자료가 신축, 증축 개축 이전 대수선, 용도변경 등으로 분류되어 수록돼 있다. 한편 국내에서 건축물에 대한 내진설계기준이 1988년에 제정됨에 따라 법제화되었다. 이때 내진설계의 의무 대상건축물은 6층 이상 또는 연면적 1만$m^2$이상인 건축물로 규정되었다. 그 이후 내진설계 대상 건축물이 1996년부터 아파트는 5층 이상으로, 판매시설은 연면적 5천$m^2$이상으로 확대되었고, 2000년부터 숙박시설 오피스텔 및 기숙사는 5층 이상으로 확대되었으며, 2005년부터 내진설계 의무화 대상이 3층 이상 또는 1천$m^2$이상으로 확대되었고, 2009년부터 3층 이상 건축물의 구조안전의 확인을 위한 세부절차를 규정하여 내진설계의 실효성을 확보하고 있다. 이와 같이 내진설계의 대상 건축물이 내진설계기준을 제정한 이후 현재까지 시대의 흐름에 따라 6층 이상에서 5층 이상으로 다시 3층 이상으로 계속 확대되어왔다. 이런 환경에서 현재 시점에서 사용 중인 기존 건축물 중에 내진설계가 적용되지 아니한 건축물은 1988년 3월 1일 이전에 건축허가 된 건축물과 그 이후에 건축허가 된 3층 내지 5층 이하인 저층 건축물의 두 가지로 구분할 수 있다. 이들의 내진설계가 미적용 된 건축물에 대해서는 원칙적으로 내진보강 대책 수립 및 추진이 필요한 실정이다. 국내에서는 현재 지진재해대책법에 따라 지진재해로부터 국민의 생명과 재산을 보호하기 위하여 기존 시설물에 대한 내진대책을 추진하는 정책이 시행되고 있다. 앞으로는 이 정책의 일환으로 기존 건축물의 내진성능 확보를 위한 내진보강 대책이 구체적으로 추진될 전망이다. 이와 같이 기존 건축물에 대한 내진보강 대책을 수립하는 데는 무엇보다 그 대상 건축물의 수와 구조형식에 관한 정보가 필요하다. 이는 내진보강의 방법과 소요비용이 건축물의 층수 및 구조형식별 동수에 따라 크게 달라지기 때문이다. 이런 관점에서 살펴볼 때 내진대책의 수립에 필수인 기존 저층 건축물의 층수 및 구조형식별 동수에 관한 통계자료를 현재 건축물의 현황통계에서 손쉽게 찾아 볼 수 있으면 좋겠는데 현실은 그렇지 못한 실정이다. 현재 건축물의 현황통계에는 저층 건축물에 해당하는 층수에 관한 구분이 연대에 따라 다르고 구체적인 층수를 구분하기 어렵게 불분명한 항목으로 구성된 것과 구조형식별 분류항목이 없는 형편이다. 반면에 건축허가 및 착공통계자료에는 구조재료별 건축물 동수와 연면적에 관한 자료가 수록되어있고, 건축물 층수에 따라 분류된 통계자료는 없다. 이 연구에서는, 기존 건축물에 대한 내진보강 대책을 수립하는데 필요한 저층 건축물의 층수 및 구조재료별 동수 등에 관한 구체적인 정보를 파악하기 위하여, 건축물 통계연보에 수록된 건축물 현황통계자료에서 불명확하거나 결여된 정보를 건축허가 및 착공 통계자료로부터 얻은 정보로 보완과 보충하여 제시하고 있다. 따라서 이 연구는 기존 건축물의 내진보강 대책 수립에 필요한 5층 이하의 저층 건축물에 관한 층수별 및 구조형식별 동수에 관한 연도별 통계자료를 추정하여 제안하는데 그 목적이 있다.

Recently, mining facilities have being installed in an underground space according to a social demand for environment-friendly mine development. The underground structures for mining facilities usually requires a large volume of space with width greater than height, and thus the stability assessment of the large-scale underground mine structure is an important issue. In this study, we analysed a factor of safety based on strength reduction method, and proposed a numerical design approach to determining the dimension of underground mine structures in combination with a strength reduction method and a multivariate regression analysis. Input design parameters considered in the present study were the stress ratio and shear strength of rock mass, and the width and cover depth of underground mine structures. The stabilities of underground mine structures were assessed in terms of factor of safety under different conditions of the above input parameters. It was calculated by the strength reduction method, and several kinds of fit functions were obtained through various multivariate regression analyses. Using a best-fit regression model, we proposed the charts which provide preliminary design information on the dimension of underground mine structures.

With the changing of social needs and paradigms, citizens are concerned about aesthetic and cultural community gardens from productive urban farms in Korea. It is still difficult, however, to cultivate a beautiful garden with a community to design, install and manage it. Therefore, this study analyzed the community garden design guidelines of other countries to derive the characteristics and implications. The research method analyzed six guidelines for community garden design in the UK, Canada, the USA, Australia and Japan. As a result of the study, most community garden design guidelines are opened freely via on-line service. The guidelines are composed with chronological processes such as intro, site selection, design, construction and maintenance. The introduction section treats definition, purpose, meaning, efficiency and success factors for community gardens. Site selection emphasizes site conditions (soil, light, shadow, water, etc.), landholding and insurance. The design section, however, lacks adequate drawings and case images. These guidelines offer little explanation with few illustrations and sentences. Construction sections explain about plantings, facilities, expense and details. The maintenance guidelines of community gardens contain how to control members, funding, harvesting, pests and plants. In addition, some guidelines include vandalism, organic cultivation methods, recording and advertisement. Lastly, the appendix contains a variety of checklists, administrative documents, guidelines, drawings, and contacts. This study will help understand the trends and characteristics of overseas community gardens design guidelines so as to also supply directions for guidelines to be introduced in Korea.

Vehicle emissions have been known as a critical factor to give a negative impact on the public health. In particular, particulate matters(PM) and NOx are highly related with respiratory diseases such as asthma. This study aimed at analyzing spatio-temporal patterns of PM and NOx generated from urban freeway traffic. MOVES, which is a well-known emission analysis tool presented by US Environmental Protection Agency(EPA), was applied to estimate PM and NOx based on traffic volume and speed data obtained from Seoul Outer Ring Expressway during January~June, 2012. K-means clustering analysis was used for categorizing the Level of Vehicle Emissions(LOVE) to support more systematical identification of the significance of emissions. Then, spatio-temporal analyses of estimated emissions were conducted by LOVE. Finally, this study proposed a set of strategies to reduce both PM and NOx to enhance public health based on analysis results.

Allocated water storage of dam at the planning and design stage does not seem to be maintained well at the operation stage because of unexpected critical reasons. A dam is likely to be subject to negative effects caused by changes of dam operation conditions and it is hardly avoidable. Therefore, it must be timely improved to recover its original functions and looked for better alternatives to keep its original roles. Specifically the improper management of river condition degrades flood control capability in a dam and river eco-system. The dam downstream river improvement work is needed for normalizing dam functions and its valuations. This study focuses on estimating water use benefits from recovering its own effective storage buffer restricted for flood control. As the results, the water supply and the hydropower benefits in Imha, Daechung and Youngdam Dam are recovered totally by 19.9 million $m^3$/year and 20.8 GWh/year respectively. Also those results are used for the basic information of the economic analysis in the dam downstream river improvement work.

Current roads were designed and constructed based on the design criteria and thus those were overly simplified drivers' needs. The road criteria do not suggest the desirable range of the design values but suggest the minimum requirements for the road design. Therefore, a completed road design based on the design criteria does not always guarantee the best design in terms of safety and it sometimes violates drivers' expectation. Therefore, the ROSSAV(ROad Safety Survey and Analysis Vehicle) is being developed by the KICT to evaluate road safety and increase driving safety. In this paper, the image capture system was described in detail. The image capture system is consisted of two front view cameras, two side down-looking cameras and a synchronization device. Two front view cameras were used to take a picture of road and road facilities at the driver's viewpoint. Also, two side down-looking cameras were used to capture road surface image to extract lane markings. A synchronization device were used to generate image capturing signal at the fixed distance spacing huck as every 10m. The front view images could be used to calculate and measure highway geometry such as shoulder width because every image is saved with it's locational information. And also the side down looking images could be used to extract median lane mark which representing road alignement efficiently.
