The number of empty houses during normal working hours is rising. As a result, the number of uninspected electric installations for general use is increasing. To define the potential risk of the electric installation, measurement of leakage current has been getting considered but because the measured leakage current value also contained leakage current by capacitance, the measured value can not be adapted to absolute reference to the installation. Therefore in this paper, the correlation between the condition of electric installation and leakage current were analyzed.

As the discourse on Anthropocene grows, this exploratory research investigates the interrelationship and interconnectivity between humanity and technology by analyzing a sound art installation created by the author. Crying Sea is a sound installation that uses plastic wastes collected from the shore to create symbolic narratives and artistic experience connecting humans, objects, and nature through interactive digital technology. In this installation, the audiences are guided to walk over the wastes, and the sounds created by the footsteps are recorded in real-time, which then are distorted and amplified into disturbing sounds through speakers filling up the room. In analyzing this artwork, three theories from technological, philosophical, and ecological backgrounds were used; specifically, Bernard Stiegler's pharmakon theory, Dona Haraway's cyborg manifesto, and Timothy Morton's dark ecology theory. A common factor revealed from all three theories by analyzing the Crying Sea is that humans, technologies, and all other entities within nature are interconnected and resonated. The awareness of this recursive relationship allows us to consider sustainable balancing.

Automation in construction has been restricted to special classes of tasks. Curtain walls can be handled like standard construction materials; they are heavy but breakable, and are large but require precise installation. These characteristics make the installation of curtain walls ideal for robotic automation. There are two methods for developing construction robots: The first is approving the robot performance and applying it to the current construction methods. The second is admitting the limitation of the current robot technology and trying to optimize the current method of construction to apply the robot system. In this study, we derived the performance requirements of a curtain wall-installation robot. We also tested this robot at a real construction site and evaluated its performance. Finally, the results were analyzed, and we proposed additional research.

Development of the technologies for offshore wind power is proceeding actively and the installation capacity is continuously increasing because of its many advantages in comparison with the land wind power. Accordingly, project for Southwestern 2.5GW offshore wind power plant is in progress in Korea. Design of electric power systems for offshore wind power plant is very important due to its high investment and operational costs. Hence, it needs to be designed in order to minimize costs. This way can be employed in determining the installation location of offshore substation for HVAC wind power plant. According to the offshore substation site, MV inter-array cable and HV export cable lengths vary and they change a total cost regarding submarine cable. This paper represents cost models with variables which are MV inter-array cable and HV export cable lengths to locate the offshore substation for HVAC wind power plant. It is classified into submarine cable installation cost, reactive power compensator installation cost, ohmic losses, and unsupplied energy cost. By minimizing a total cost, an appropriate installation site of the offshore substation is determined.

기존의 휴대폰을 대신하여 무선인터넷 디바이스로서 새롭게 주목 받고있는 PDA는 응용 분야가 확대됨에 따라서 수많은 프로그램 개발이 이루어지고 이와 동시에 개발된 애플리케이션은 적합한 형태로 설치되어야 한다. 또한 PDA는 배터리 전원이 방전될 경우에 RAM(Random Access Memory)에 저장되어 있던 모든 데이터가 삭제되는 단점이 있어서 램에 설치하였던 프로그램은 사용을 위해서 복원해야 하는 번거로움이 있다. 본 논문에서는 휴대 정보터미널인 PDA에 애플리케이션 설치가 필요한 경우, 사용자가 직접 애플리케이션을 설치해야 하는 기존의 문제점들을 해결하기 위하여 자동으로 응용 프로그램이 설치되는 시스템(PAIS : PDA Automatic Installation System)을 제안하였다. 이 시스템을 PDA와 같은 휴대 단말기에 적용할 경우 사용자에게는 설치에 소요되는 시간과 노력을 감소시켜 편의를 제공하고 기업에게는 프로그램 설치관련 홍보물 제작에 소요되던 비용을 절감하여 무선 인터넷의 확산을 기대할 수 있다.

The aim of this study is to review the creative fashion installation of Henrik Vibskov, Danish designer. Its intention is to contribute useful information for more innovative fashion presentation. As a research method, document and case study were performed and his collections from 2004 F/W to 2016 S/S were analyzed. In fashion installation, the designer puts objects in meaningful spaces in order to convey a certain message, to make an integrated artwork, and to interact with spectator. It has been used in fashion exhibitions, as well as in the set design of fashion performance and fashion show. The results were as follows. Henrik Vibskov's fashion installation has three features, which are 1)conceptual theme approach that communicates a twisted and metaphoric message, with a poetic and interesting show title, 2) surrealistic scenography that plays with fragmentation of the human body, clustering of plastic and symbolic objects, innovative color transformations, and visual trickery between figures and the background, and 3) setting for multisensory performance that makes spectators interact by making artistic objects and surroundings, which stimulates the five senses. Henrik Vibskov's fashion installation can exist as an independent artwork, and not just as a supporting piece for a fashion show. It has both artistic and fashionable values, and can be an effective fashion presentation communicating his conceptual fashion themes.

IEC is an international standards which are used in many countries with Europe as the center. IEC standard is introduced in Korea according to WTO/TBT agreements, however until now there are no buildings in Korea which are designed applying IEC standard. Therefore, KEA(Korea Electric Association) is scheduled to construct Korean low voltage electrical installation integration test site which is designed applying IEC standard. In this paper, before being under construction of Korean low voltage electrical installation integration test site, power substation is modeled based on real design parameters and method to select circuit breakers and cables is presented applying IEC standard in the modeled power substation. EMTP(ElctroMagnetic Transient Program) is used for simulation program. EMTP which is power system analysis program is easy to model power system and power substation.

프로그램의 소스를 공개하여 배포하는 형태는 특정 계층 사용자들의 주도로 이루어져 설치가 매우 어려웠다. 그러나, 오픈 소스로 배포하는 업체가 늘어나고 대중의 관심이 높아지면서 설치와 관련된 방법에 변화가 일어나고 있다. 전통적인 컴파일 설치뿐만 아니라 패키지 설치, 네트워크 기반 설치, 압축해제 후 파일 실행 등 사용자 위주의 기법들이 등장하기 시작했고, 개발자들이 손쉽게 다양한 플랫폼 지원을 위해 cmake를 사용한 방법도 등장했다. 본 논문에서는 오픈 소스 운영체제인 리눅스를 기반으로 소스가 공개되어 배포되는 응용프로그램의 설치 동향에 대해 분석한다.

Simultaneous implant installation with bone graft was performed in 15 cases. Four cases were cleft alveolus patients. 56 implants were placed immediately with block bone grafts. 2 cases were cranial bone grafts and the others were iliac bone grafts. Three of 56 implants were lost(94.6% Survival rate). One of three was cleft alveolus case. The cleft alveolus patients with simultaneous implants installation showed functional and esthetic results without infraocclusion and positional changes. Bergland index was considered to be type I after 12 months later. Immediate implant installation with bone graft is one of choice of treatment in closing cleft alveolus hoping simultaneous implant installation could be related with function which might result in less resorption of graft. Functional and esthetic results are satisfaction ; there was no infraocclusion and positional changes.

The G-SEED encourages the installation of new and renewable energy facilities through assessments of the new and renewable energy installation rates. The government also regulates the installation rate of new and renewable energy facilities in the 'Project on new and renewable energy obligation in public installations'. The current criteria concerning the new and renewable energy facilities in the G-SEED are the result of an amendment made in July 2010. As over five years have passed since this amendment, the assessment criteria needs to be reenforced. To improve the current criteria, the calculation results of the installation rate of new and renewable energy facilities in the G-SEED were analyzed and compared to the corresponding calculation results of the 'Project on new and renewable energy obligation in public installations'. And an improved draft for the assessment criteria of the new and renewable energy facilities in the G-SEED was proposed.
