It became clear that Korean peninsula is not a safe region anymore from an earthquake disaster after Gyeongju and Pohang Earthquake in 2016-2017. Unfortunately, building industry in Korea has not been well prepared for an earthquake disaster and the following problems exist. First, the rate of buildings with proper seismic performance is relatively low. Second, the number of piloti buildings which are vulnerable to earthquake and fire disaster has increased recently. Third, the proportion of small-scale buildings excluded from the application of the building law for securing safety is too high. Fourth, widespread corruption and poor construction impede safety. Therefore, measures to prepare for earthquake disaster are as follows. First, methods of reinforcing building structures and reducing the seismic load acting on a building should be utilized in order to secure the insufficient seismic performance of buildings vulnerable to earthquakes. Second, whistleblowers should be encouraged and protected to prevent defective construction due to corruption. To this end, whistleblowers should be recognized as an effective means of protecting public interest not the traitor to the organization.

The Study of environment monitoring through huge network of wireless sensor node is worked with activity. The sensor nodes must be very small, light and low cost. The localization which may determine where a given node is physically located in a network is one of the quite important problems for wireless sensor network. But simple localization method is required as excluding the usage of GPS(Global Positioning System) by the limit condition such as the node size, costs, and so on. In this paper, very simple method using connectivity for the outdoor RF communication environment is proposed. The proposed method is demonstrated through simulation.

In order to prevent the spread of COVID 19, the body temperature is measured when entering the building. In this paper, we try to certify the entry of the building through real-time face recognition based on the face learning data of visitors. The number of learning images are designed to be automatically labeled to increase facial recognition. Also, it designates the forehead region from the face region as the region of interest for accurate temperature measurements. In the future, we plan to establish a database that stores the temperature, access time, and information of visitors.

From public insecurity, access of wealth, alteration of population structure, and changes of security recognition, physical security has been continuously developed and changed. In these days, typical systems for physical security are unmanned security system using telephone network and security equipment, image recognition system using DVR and camera, and access control system by finger print recognition and RFID cards. However, physical security system is broadening its domain towards ICT based convergence with networked camera, biometrics, individual authentication, and LBS services. This paper proposes main technical trends and various security convergences for future physical security services by classifying the security categories into 3 parts; Individual security for personal protection, IT Convergence for large buildings, and Homeland Security for omni-directional security.

정보통신분야의 눈부신 발전 및 확산에 따라 최근의 건물에는 OA기기, 통신기기, 빌딩관리시스템기기, 보안시스템 기기 등이 도입되고 있으며 이들 기기는 동작 전류가 매우 작아 원하지 아니하는 전류에 의해 기기의 파괴, 오동작, 잡음 등의 장애가 발생한다. 그러나 이러한 기술적 변화에 따른 영향으로부터 대응할 수 있는 통신용 접지에 대해서는 소홀히 한 것이 사실이었다. 이에 국제표준화, 국내 접지현황 및 문제점을 고찰하고 인텔리전트 빌딩에 맞는 접지시스템 및 정보통신 설비별 세부 설치방법을 소개함으로써 국내 통신용 접지에 맞게 활용할 수 있는 계기를 마련하고, 더불어 접지의 중요성에 대한 인식전환의 계기가 되었으면 한다.

제품의 고급화, 정밀화, 생산성의 행상, 그리고 원가절감이 요구되는 요즈음 컴퓨터를 이용한 온라인 계측, 데이타처리 그리고 제어가 기계공학에서 차지하는 중요성이 점점 더 크게 인식되고 있다. 더욱 동력비와 연료비가 계속 상승하고 있기 때문에 건물에너지시스템, 화학공정시스템과 기타 에너지사용시스템의 온라인 모니터링(on-line moritiring)과 최적제어(에너지 사용비절감)을 위한)가 어느 때 보다도 중요성이 고조되고 있다. 본 해설을 통해서 마이크로프로세서 응용의 중요성과 일반적 방법을 잠시 생각해 보고자 한다.

최근 급속히 발전하고 있는 유비쿼터스 컴퓨팅의 대두는 센서네트워크 산업 발전에 않은 영향을 끼치고 있다. 센서네트워크는 군사, 과학, smart home, 환경, 농업등 많은 분야에 응용할 수 있으며, 기존의 유무선 네트워크와 항께 미래를 같이할 차세대 네트워크로 평가 받고 있다. 본 논문에서는 저전력 무선 센서네트워크인 MICA2[1]를 이용하여, room size의 건물내의 공간에서 3자원위치를 인식 및 추적 할 수 있는 저가형 시스템에 대하여 설계 및 구현한다.

스마트 빌딩 시스템에서 건물내 설치된 온도센서를 통하여 인식된 온도를 효율적으로 데이터베이스화함으로써 기존 화재방지 설비가 가지지 못한 열이동을 추적할 수 있는 데이터베이스를 구축하게 된다. 이를 통해 화재의 이동을 데이터베이스상에서 추적함으로써 설비를 정확하게 조작할 수 있게 되어 기존의 방식보다 화재방지에 효과적인 데이터베이스 구축이 가능할 것이다. 또 구축된 온도 데이터베이스로부터 화재예방과 관련한 정보를 쉽게 질의처리하여 사용자가 화재 위험요소를 사전 제거하고, 화재방지 시스템의 정상적인 관리를 가능케 할 것이다.

This study was to analyze the changes made in the landscape cognition in Yong-in City for the past 10 years. For the analysis, the landscape plan in 2001, and the survey data collected for the new 2012-landscape plan were used. The questions on the survey covered the cognition of the current landscape status, the evaluation of landscape depending on the types of landscape, the understanding of each element on the landscape, the residents' cognition, etc. In the evaluation of the status on current landscape, Everland was ranked outstandingly high as a symbol and a representative place both in 2001 and 2012. The image of the overall city landscape was changed from the image of unique, diverse, grand-scale and well ordered in 2001, to the image of wide, disordered, common and realistic. As the evaluation of individual landscape types such as the view of the mountain, the surroundings of the tourist attractions, colors, etc, has improved overall. The image of the city has been evaluated to improve gradually, especially in the level of individual element. In the study of participating the willingness of residents, despite the interest in landscape has been continued, the attitude for the actual participation in the action plan or the restriction of property right has been changed into a negative side. For the direction of the landscape plan, the residents are more interested in the detailed subjects : such as the financial support, the night landscape plan, the improvement of the problems, etc. During the last 10 years, the changes on the landscape cognition in Yong-in City have changed more in detail and specifically, the cognitions on the local government and developers changed positively. However the reducion of the participants' willingness suggested a review on the policies and the projects of the landscape.
