In modern society, citizens' quality of life aspects of safety and crime prevention activities are actively considering the incidence of crime prevention in advance. It also can be quite important elicit the interest of who community members through effective crime prevention strategies. For crime prevention policies and techniques over time as more scientific and advanced methods are made. Today, A typical crime prevention strategies is private security zones and Crime Prevention Through Environmental Design (CPTED) is a corresponding to the new strategy. CPTED is a diversification can be called a crime prevention approach that emphasizes the principle of natural surveillance, access control, territoriality, activity support, maintenance and management. The defensible space of the space area related to crime prevention setting the activities of private security and CPTED determine. Also, the reality of crime prevention and protection should be considered space. The emphasis on proactive prevention of crime in modern society for the prevention of crime how to approach differing perspectives and disparate aspects of private security and CPTED. Technical and professional areas that overlap to some extent in a homogeneous aspect. Ultimately, CPTED is a crime prevention through space and environmental approach for crime. In addition, Ultimate goal of convergence, crime prevention, with the same or higher is required to study for the area after looking for the characteristics and limitations of private security and CPTED.

Humans are influenced by economic factors, physical environment factors, social and environmental factors, influenced by the media. In particular, the occurrence of the crime for fear of crime due to the human activities of the area has reduced. Fear of crime inflienced by direct victim of a crime, disorder of the surrounding environment, and indirect victims of crime. Therefore, in order to reduce their fears about crime in the private security through crime prevention and. About the factors affecting their fears about crime in the actual selection of the private security and private security activities in order to solve these problems through crime prevention, through this study will be described. In this study, we randomly select the survey was in August 2011, as detached house in Seoul and Daegu. As a result, the fear of crime fears about crime were influenced directly or indirectly by factors of private security selection.

As to the increase of crime against children, the importance of safety in school area is more emphasized ever. Safety in school area can be achieved by the well-organized combination of physical, managemental and spatial planning factors. The purpose of this paper is to investigate the spatial planning direction to prevent crimes for the schools and their surroundings on the viewpoint of CPTED(crime prevention through environmental design). Field survey using checklist drawn up with 5 major CPTED principles was conducted for 7 schools(primary, middle and high schools) located at Noen New-town, Daejeon Korea. Problems derived from field survey were categorized to 5 CPTED principles and countermeasures were suggested together with computer graphic simulation. CPTED design principles and guidelines for spatial planning can make school area safer because these can assure natural surveillance, territoriality, natural access control, etc.

Biomass burning activities(BBA) are caused by both natural and anthropogenic origins. Due to emissions of greenhouse gases and atmospheric aerosols during the burning process, BBA has been known to be one of important sources of atmospheric pollution and the climate change. However, the monitoring of BBA and its effects on atmospheric environment are not simple. This study evaluates the trends of BBA and its impact on atmospheric environment by using earth observing satellite. The results show that the most BBA were found over ever green, green vegetation types, and irrigated land cover types in study region. The trends of BBA and aerosol optical thickness which represents relative aerosol loading in the atmosphere, show similar pattern. Aerosol increases caused by BBA highlight the effectiveness of these mechanisms and would affect the regional atmospheric environment and climate change.

Morphological changes in immune cells occur due to pathogen infection and natural circulation. T cells produce uropod, filopodia, lamellipodia, and microvilli for inflammation, immunosurvelliance, migration, and diapedesis. Short finger-like microvilli cover the surfaces of circulating mammalian immune cells. The surface features of monocytes and neutrophils are quite different, containing membrane ruffles as their predominant structure. In this study, we present the involvement of actin cytoskeleton regarding T lymphocyte microvilli. From analysis of scanning electron micrographs, Jurkat T lymphocyte microvilli was observed to rapidly disassemble when exposed to the actin-sequestering molecule, cytochalasin D. In contrast to cytochalasin D treatment, we found that median microvillar thickness was enlarged on Jurkat T lymphocytes treated with PMA via Lin-11, Isl-1, Mec-3 Kinase (LIMK) and cofilin signaling. In addition, actin cytoskeleton was involved in polarity formation in EL4 T lymphocytes. These results suggest that microvilli formation or polarity of T lymphocytes are involved in actin cytoskeleton dynamics.

With an increase in urban crimes in various forms, this study is intended to analyze the effectiveness of the service design that presented a new model resolving crime risks through differentiated thinking paradigm and problem approaches. The empirical case addressed in this study is 'the project to create resident-driven safe community in Duryu-dong, Dalseo-gu, Deagu though service design'. This project is evaluated as having prepared a prevention-oriented local safety system through a preemptive and resident-centered process. The project was promoted as a 'natural monitoring capacity building program' for residents to prevent local crimes, a 'social role expansion program' for local safety, and 'crime prevention environment design', which provides comprehensive solutions for residents' safety. Here, designers act as exerts in designing a task-based platform that can be driven by residents rather than a visual environment improver, and reorganizing the local ecosystem by expanding the opportunities for residents to interact. This case identifies the role of service design as binding the solidarity of local residents beyond the improvement of the crime environment and giving them the potential capacity to maintain a safe living space in relation to a safety issues of community.

전 세계에서 홍수로 인한 인명손실과 재산적 피해의 기록을 살펴보면 최근 몇 년 동안 꾸준히 증가하고 있다. 이로 인해서 홍수를 방어하기 위한 노력은 증가하게 되었다. 이로 인해 홍수터에서 인구집중과 개발로 인해 홍수방어를 위해서 막대한 투자가 필요하다. 이와 동시에 지속가능하고 효과적인 수자원 관리는 전체적인 접근방법이 요구되며, 사회와 경제발전과 생태계 보호 및 토지이용과 수자원 이용의 적절한 관리와 연결된 개념이 필요하다. 유역은 육지와 수계 사이의 많은 상호작용이 있는 동적인 시스템이다. 이러한 관점에서 유역을 간단한 고정된 지역적인 문제라고 생각하는 것보다 전체로서의 유역 기능을 개선하는데 노력이 필요하고 시도되어야 할 것이다. 통합홍수관리(IFM : Integrated Flood Management)는 홍수의 긍정적인 측면과 부정적인 측면을 고려한 새로운 접근방법이며, 홍수가 자원적 가치를 지닌 것이라고 생각하는 개념이다. 통합홍수관리의 특징은 홍수조절 대책의 적절한 혼합, 대책의 목적 및 형태(구조적 및 비구조적 대책), 단기간 및 장기간 대책 등의 대책들을 통합하는 것이다. 여기에는 전유역의 수문순환 관리, 통합 토지이용 및 수자원 관리, 최적 혼합대책의 적용 및 통합재해관리 적용 등이 있다. 홍수는 자연적인 수문학적 체계의 중요한 요소이며, 주요 수자원이기도 하다. 그리고 빈번한 홍수로 인해 제방을 넘어 홍수터를 점령한다. 이 결과로 상습 홍수범람지역은 점점 더 인구가 밀집되고 있고 홍수에 더 취약하게 된다. 그러므로 금호강유역에 발생한 홍수의 개요, 원인 및 결과에 대해서 살펴보고, 홍수관리대책과 실효성에 대해서 조사 분석하였다. 그리고 홍수가 발생한 후 홍수관리대책과 관리기술의 변화를 통합홍수관리의 개념에서 분석하였다.Jones matrix, which allows a new interpretation in the conversion efficiency of the thin-film optical waveguides.있다는 장점이 있었다. 따라서 소아에서 복막투석도관 수술 시 복강경적 방법을 이용하는 것이 효율적인 복막 투석을 위해 유용하다고 생각된다.상부 방광천자에 비해 민감도 59.5%(25/42), 특이도 86.6%(13/15)였고 위양성률 13.3%(2/15), 위음성률 40.5%(17/42) 로 정확도가 낮았다. 결론 : 소변을 가리지 못하는 영유아에서 요로 감염을 진단하기 위해서는 도뇨관 채뇨에 비해 초음파 감시하 치골상부 방광천자가 정확하고 안전한 채뇨법으로 권장되어야 한다고 생각한다.應裝置) 및 운용(運用)에 별다른 어려움이 없고, 내열성(耐熱性)이 강(强)하므로 쉬운 조건하(條件下)에서 경제적(經濟的)으로 공업적(工業的) 이용(利用)에 유리(有利)하다고 판단(判斷)되어진다.reatinine은 함량이 적었다. 관능검사결과(官能檢査結果) 자가소화(自家消化)시킨 크릴간장은 효소(酵素)처리한 것이나 재래식 콩간장에 비하여 품질 면에서 손색이 없고 저장성(貯藏性)이 좋은 크릴간장을 제조(製造)할 수 있다는 결론을 얻었다.이 있음을 확인할 수 있었다.에 착안하여 침전시 슬러지층과 상등액의 온도차를 측정하여 대사열량의 발생량을 측정하고 슬러지의 활성을 측정할 수 있는 방법을 개발하였다.enin과 Rhaponticin의 작용(作用)에 의(依)한 것이며, 이는 한의학(韓醫學) 방제(方劑) 원리(原理)인 군신좌사(君臣佐使) 이론(理論)에서 군약(君藥)이 주증(主症)에 주(主)로 작용(作用)하는 약물(藥物)이라는 것을 밝혀주는 것이라고 사료(思料)된다.일전 $

Wildfires cause a lot of environmental and economic damage to the Earth over time. Various experiments have examined the harmful effects of wildfires. Also, studies for detecting wildfires and pollutant emissions using satellite remote sensing have been conducted for many years. The wildfire product for the Geostationary Environmental Monitoring Spectrometer (GEMS), Korea's first environmental satellite sensor, has not been provided yet. In this study, a false-color composite for better expression of wildfire smoke was created from GEMS and used in a U-Net model for wildfire detection. Then, a classification model was constructed to distinguish yellow dust from the wildfire smoke candidate pixels. The proposed method can contribute to disaster monitoring using GEMS images.

The need for recognizing the crime in the urban spaces as a social problem and finding out specific approaches such as the study of space design and various guidelines for crime prevention is increasing. In this regard, "Crime Prevention Through Environmental Design" (marked as "CPTED") is actively underway. Yeomri-dong Salt Way is the first place to which the Seoul Crime Prevention Design Project was appled. The business objective of improving the local environment has been implemented rationally through cooperation and voluntary participation between subject of the project executives and community members. Since its efficiency has been proven, the sites have been expanded since then and becomes a benchmarking example of each local government.This kind of problem solving effort has the same context in purpose and direction of the 'Village Art Project' which has been implemented since 2009 with the aim of promoting the culture of the underdeveloped area and encouraging the participation of the residents by introducing the public art. It is noteworthy that this trend is centered around the characteristics of community functions and values. The purpose of this study is to propose the application method of community furniture as a way to increase the efficiency of CPTED to improve the 'quality of life' of residents. To do this, we reviewed CPTED, community design, public art literature and prior research, and identified the problems and implications based on the site visit Yeomri-dong of Seoul and Gamcheon Village of Pusan which is the successful model of "Seoul Root out Crime by Design" and 'Maeulmisul Art Project' respectively. The common elements of the two case places identified in this study are as follows: First, the 'lives' of community residents found its place in the center through the activation of community by collaborative activities in addition to the physical composition of the environment. Second, community design and introduction of public art created a new space, and thereby many people came to visit the village and revitalize the local economy. Third, it strengthened the natural monitoring, the territoriality and control, and the activity increase among the CPTED factors. The psychological aspect of CPTED and the emotional function of public art are fused with the 'community furniture', thereby avoiding a vague or tremendous approach to the public space through a specific local context based on the way of thinking and emotion of local people and it will be possible to create an environment beneficial for all. In this way, the possibility and implication of the fusion of CPTED and public art are expected to be able to reduce the social cost through the construction of the crime prevention infrastructure such as expansion of the CPTED application space, and to suggest a plan to implement the visual amenity as a design strategy to regenerate city.
