최근에 출시된 포켓몬고는 위치 기반의 실시간 증강 현실을 모바일로 구현한 온라인 게임이다. 이 게임의 올바른 플레이는 사용자들이 직접 이동해가며 출현하는 포켓몬을 수집하는 것을 기본 전개로 해야 하지만, 인기가 많아짐에 따라 쉽게 플레이하기 위한 악용 사례가 생겨났다. 가장 많이 사용되는 방법은 Fake GPS와 같은 모의 위치 서비스를 제공하는 애플리케이션을 사용하는 것으로, 이러한 애플리케이션을 이용하면 실내에서 이동하지 않고도 게임을 할 수 있기 때문에 온라인 게임에서의 부정행위로 판단할 수 있다. 이와 같은 부정행위를 클라이언트 관점(모바일 기기)에서 탐지하면 시스템 자원을 많이 소모할 수 있어 게임 속도를 급격히 저하시킬 수 있다. 개발사 입장에서는 게임 사용성과 사용자 만족도에 부정적인 영향을 주는 탐지 방법은 적용시키기가 어려운 실정이다. 따라서 본 논문에서는 서버 관점에서 GPS 위치 기록을 활용하여 생성한 이동경로를 분석하여 모의 위치 서비스를 온라인 게임에서 악용하는 사용자를 탐지하는 기법을 제시한다.

본 논문은 금속파편이 발생시 금속파편의 위치를 추정하기위한 위치 추정 알고리즘을 제안한다. 이 추정 알고리즘은 자동화된 알람 구별부와 위치 추정부로 구성된다. 알람 구별부는 충격 신호인지 거짓 충격 신호인지를 구별하는 기능을 수행하며, 위치 추정부는 충격신호로부터 충격신호의 시작점을 찾아내어 위치를 추정한다. 이 알고리즘의 타당성을 검증하기위해 원자로 Mock-up 상에서 실험한 결과 위치 추정값 과 실제 충격값이 약 10 % 이내의 오차율을 보였다.

The ultimate objective of this research is to develop the technologies for the construction of 100-year housing as the first task for improving housing environments. The technological development of 100-year housing makes it possible to advance construction technologies and part development, to develop long-life housing with durability and Flexibility responding to customers' needs for future living space. At first, for this purpose, the applications according to the types of the Standard Model of Long-life Housing are proposed to respond to the life-cycle of near-future demographic and social structure, and the construction of the Mock-up House execute based on the location selected during the 2nd year and the basic plan. Then the Standard Model of Long-life Housing are advanced and proposed through evaluating the field applicability of the Mock-Up House.

주광은 인공광원보다 심리적 안정과 심리적 신체적 건강 측면 등에서 질적으로 우세하며, 작업능률의 향상에 도움을 주는 것으로 알려져 있다. 또한 쾌적한 빛 환경에 대한 재실자들의 요구가 증가하고 있다. 그러나 주광의 양과 질이 항상 일정하지 않아 예측하기가 어렵기 때문에 이러한 주광의 유용성에도 불구하고 건축설계에 주광을 적극적으로 반영하는 경우가 드물다. 본 연구의 목적은 이러한 주광의 성능을 계량화하고 가시화 할 수 있는 다양한 조명시뮬레이션 소프트웨어(Lightscape 3.2, Relux 2007, Radiance 3.9)를 사용함으로 주광을 예측하고, 도출된 결과 값과 Mock-up 실험의 실측값을 비교 분석을 통하여 조명 시뮬레이션 소프트웨어 활용성을 극대화하는 것이다.

To design mechanical ventilation for bathroom of apartment houses where air supply and exhaust are taken Into consideration, mock-ups of ventilation systems, widely used in bathroom of apartment houses with an area of 100$m^2$, were made and installed in a laboratory, These ventilation mock-ups were available for control of air supply and exhaust, and the size of supply openings were 40cm$\times$1cm, 40cm$\times$3cm, 40cm$\times$5cm. They were installed at five positions, spaced 40cm at a height of 25cm from the floor. and the position of exhaust fans were four corners and center Exhaust fan established each one on corner of the ceiling and one in center. As result that measure ventilation effect by each condition, size of hole that supply air is big, and ventilation effect took effect to be good establishment location is low, Also, distance of exhaust fan is far with hole that supply air, ventilation effect took effect by superior thing.

Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in a room. Architecture design has need of daylight prediction for reflection efficiently daylight. But it is difficult to predict the illuminance values in daylight system. Using various lighting simulation software is easy and simple, but we can find different results under the same conditions. This study compares with illuminance values from simulation (Lightscape 3.2, RELUX 2007, RADIANCE 3.9) and Mock-up experiment with the same space and parameter of daylight (location of space and window, date, time and sky condition).

The mock-ups of ventilation system, which has been widely adopted for the bathroom with the area of 100 $m^2$ apartment housing, were established and tested to design mechanical ventilation for apartment housing bathroom where air supply exhaust are relatively important. These ventilation mock-ups were capable of controlling intake and exhaust, which has the size of supply openings as 40cm${\times}$1cm, 40cm${\times}$3cm, 40cm${\times}$5cm. They were established at five locations, spaced 40cm from each other at a height of 25cm from the floor. The exhaust fans were located at four corners and center of the ceiling. The results this ventilation effect measurement by different condition are showing that when the size of air supply is bigger and the location is lower, the effect of ventilation was relatively higher. In addition, as the distance between exhaust fan and air supply was farther, the ventilation effect were getting highly efficient.

A novel technique has been proposed and related experimental works have been performed in order to detect the partial discharges and the location of the possible defects introduced into the Gas Insulated Switchgear. For this purpose, a prototype HY Pockels sensor has been developed and then employed in order to investigate its field applicability for finding the location of the defects using a 170kV GIS mock-up. Our proposed sensor enables us to measure the electric field variation due to the PD occurrence. In addition, the different PD patterns are observed, which might be dependant on the location and the distance of the sensor with respect to the PD source. Throughout this work, its linear response has been proved to be admissible as a function of the applied voltage. And also the position of the PD source might be distinguished by comparing the PD patterns.

In this paper, a real time diagnostic algorithm fur estimating the impact location by loose parts is proposed. It is composed of two modules such as the alarm discrimination module (ADM) and the impact-location estimation module(IEM). ADM decides whether the detected signal that triggers the alarm is the impact signal by loose parts or the noise signal. When the decision from ADM is concluded as the impact signal, the beginning time of burst-type signal, which the impact signal has usually such a form in time domain, provides the necessary data fur IEM. IEM by use of the arrival time method estimates the impact location of loose parts. The overall results of the estimated impact location are displayed on a computer monitor by the graphical mode and numerical data composed of the impact point, and thereby a plant operator can recognize easily the status of the impact event. This algorithm can perform the diagnosis process automatically and hence the operator's burden and the possible operator's error due to lack of expert knowledge of impact signals can be reduced remarkably. In order to validate the application of this method, the test experiment with a mock-up (flat board and reactor) system is performed. The experimental results show the efficiency of this algorithm even under high level noise and potential application to Loose Part Monitoring System (LPMS) for improving diagnosis capability in nuclear power plants.
