Safety inspections of outdoor advertisements are conducted to determine the aging status, specifications, and compliance with design documents. Regular inspections are conducted on outdoor advertisements from a safety perspective, as they not only undermine the aesthetic elements of the city but also could cause falls on roads or pedestrian paths. However, the current safety inspection methods are at risk of various accidents during the inspection advertisements on the outer wall of the building. And it is difficult to conduct in-depth inspections on them if they are fixed to the elevation of the building. Furthermore, there also is a risk of safety accidents, such as advertising structures falling onto a pedestrian path. Therefore, this paper aims to enhance the safety inspection system of outdoor advertisements using drones. This paper also intends to propose measures for facility inspection history management such as safety inspection cycle, maintenance, and removal of signboards.

As longevity of human-beings is extended and the population of aged people increases, diverse issues related with the aged people are presented. The neighborhood space for the aged people is required to be designed based upon the understanding of such difficulties of the elderly and the public outdoor environment is an important environmental resource that can enhance the quality of life and promote the health of the elderly in underprivileged area without burdening them economically. This study aims to research the daily life of the elderly in underprivileged urban area and their utilization styles of outdoor environments in order to find out the push factors and pull factors that induce the aged people to use the outdoor environments. For this purpose, this study carried out an interview survey upon 69 elderly residents and surveyed on 363 elderly residents of low income class who are aged 60 and over and living in decaying area in Jeonju. For the analysis of the collected data, a qualitative and a quantitative analysis were accomplished. As results of study, the elderly in underprivileged area use such outdoor environments as resting facilities, exercise equipment, parks, farming gardens and waterfronts, and the push factors for them to use the outdoor environments were sordid indoor spaces, sense of isolation or loneliness, and the desire for maintaining good health. And the pull factors for them to use the outdoor environments were natural factors, opportunities for social interactions, space for exercise. The obstacles that hinder the elderly in using outdoor environments were the bad health of the elderly, lack of facilities, accessibility and weather conditions. Thus, the results of this study are expected to provide basic data for designing the outdoor environments to promote the health of the elderly in urban underprivileged area and to relieve the burdensome problems related with ageing societies.

This paper is concerned with the Performance and Reliability Certification for fire detection system in outdoor area such small and middle sized cultural assets, natural monument and outdoor facilities. Especially, if a fire were to occur in vulnerable area, it is difficulty to detect a fire. therefore we propose a high efficiency and low cost unmanned fire detection system in capable of an early detection regardless spontaneously fire or firebug. for Adoption of Intelligent Fire Detection System with movable and unmanned function breaking from the existing Conventional Fire Detection System, this Range of R&D includes the Performance test, Function test, Field test, Flame Detection test and EMI/EMS Compliance test. the Result data of Performance test, Function test and Field test is generally good during 3 months. also we checked that thermal variation test and EMI/EMS compliance test are good result data within allowable range. As a result of general test, we verified improvement results that the measure distance of fire detection extend 75 m, the Power of waiting time increase 4 hours, the Power of operation time increase 3 days and the context awareness with video as well as sensors.

도시의 옥외광고는 정보전달매체로서의 역할 뿐만 아니라 그 시각적 표현은 도시미관을 형성 하는 중요한 요소 중 하나이다. 따라서 현대의 간판은 한 지역의 사회적 문화적 수준을 판가름하는 척도로 인식될 만큼 그 중요성이 강조되고 있다. 또한 도시환경 속에서의 간판은 시민들이 항상 접하고 있는, 시민들의 삶의 질에 밀접하게 연관되어 있다. 간판은 이제 상점을 홍보하는 단순한 사물이 아니라 건물과 가로수, 광고의 내용물, 도시 시민들과의 유기적인 조화를 고려하여 만들어야 하는 도시환경구성의 주요 요소로서 접근해야 한다. 따라서, 부분적 요소인 간판을 통해 도시 미관과 환경을 효율적으로 조율하여 쾌적한 도시환경을 조성해야 할 필요가 있다. 본 연구는 중국, 장춘시 상업지역을 중심으로 사인보드의 실태를 수집분석하고 그에 따른 문제점을 연구하고 개선방안을 제시하는데 목적이 있다.

Environmental design pattern of the nine Small Urban Spaces at C.B.D. in City of Seoul are surveyed and analyzed for user's satisfaction and behavior under the environmental design evaluation by using Christopher Alexander's Pattern Language. Small Urban Spaces as a part of streetscape are formed by physical factors as well as visual environment and interacting user's behavior. Therefore, user's satisfaction and behavior at the nine Urban Small Spaces were investigated under the further search for some possibilities of application of those Pattern Languages. A pattern language has a structure of a network. It is used in sequence, going through the patterns, moving always from large patterns to smaller, always from the ones which create comes simply from the observation that most of the wonderful places of the city were not blade by architects but by the people. It defines the limited number of arrangements of spaces that make sense in any given culture. And it actually gives us the power to generate these coherent arrangement of space. As a results, 'Plaza', 'Seats'and 'Aecessibility' related design Patterns are highly evaluated by Pattern Frequency, Pattern Interaction and their Composition ranks, thus reconfirm Whyte's Praise of urban Small Spaces in our inner city design environments. According to the multiple regression analysis of user's evaluation, the environmental functions related to the satisfaction were 'Plaza', 'Accessibility' and 'Paving'. According to the free response, user's prefer such visually pleasing environmental design object as 'Waterscape' and 'Setting'. In addition to, the basic needs in Urban Small Spaces are amenity facilities as bench, drinking water and shade for rest.

위치기반서비스는 기본적으로 사용자의 위치를 파악해야 한다. 측위방법은 옥외용과 옥내용으로 구분되며, 옥외용에는 GPS 방법, 이동통신망을 이용한 방법, GPS와 이동통신망을 복합적으로 활용한 방법이 있고, 옥내용에는 적외선을 이용한 방법, 초음파를 이용한 ActiveBat과 Cricket, RF 신호를 이용한 RADAR가 있다. 기존의 옥외용 측위방법은 옥내에서는 사용이 제한되고, 기존의 옥내용 측위방법은 특수한 환경을 꾸며주어야 하는 단점이 있다. 본 논문에서는 이러한 단점을 보완한 방법으로 GPS 수신모듈과 무선LAN용 AP의 신호의 세기를 이용하여 사용자의 위치를 판단하는 옥내외 통합 측위시스템을 소개한다. 검증을 위해 제안하는 시스템을 구현해 보았으며, 실험 결과로 성능평가를 한다.

사용자의 위치를 파악하는 것은 위치기반서비스 시스템 개발에 필수 요소이다. 본 논문은 액세스 포인트의 신호의 세기를 참조하여 사용자의 위치를 파악하는 방법을 소개한다. 기존의 위치 파악 시스템은 옥외용과 옥내용으로 분류되고, 옥내용은 실내의 일정 영역에 적외선 센서를 부착하거나, 천정에 초음파와 RF 신호 발생기를 부착하는 등 특수한 환경을 꾸며주는 것이 필수적이다. 옥외용으로는 GPS가 대표적으로 사용되는데 옥내에서는 GPS 데이터를 수신할 수 없다는 단점이 있다. 근래에 들어 무선 랜이 흔히 설치됨에 따라 본 논문은 무선 랜에 이미 설치된 액세스 포인트의 신호 세기를 이용한 측위 방법을 제안한다. 이 방법은 무선 랜이 설치된 곳이라면 옥내나 옥외에서도 적용이 가능한 장점이 있다.
