화재감지기는 화재시 발생되는 열, 연기, 불꽃, 독성가스등의 다양한 연소생성물을 감시한다. 기술의 발전으로 화재 감지방식과 기능이 다양해지고 있으며, 이에 따라 다양한 방식의 감지기들이 개발되고 있다. 최근 진보된 감지기들은 화재로 발생 이전에서 부터 감지, 비화재보에 대한 방지는 물론 감지기의 상태 오염 감도 등의 다양 정보를 제공함으로써 유사시 신속하고 정확한 대응이 가능하도록 발전되고 있다. 이러한 진보된 감지기는 막대한 피해가 예상되는 장소, 대피하는데 많은 시간이 소요되는 장소에 적용되어 인명 및 재산피해를 절감 시키고 있다. 일산화탄소감지기 또한 진보된 감지기로 화재 초기 가연물이 연소할 때 발생하는 일산화탄소를 감시한다. 일반화재의 경우 화재 초기에 가연물이 서서히 연소시 불완전 연소로 인한 다량의 일산화탄소가 발생되기 때문에 기존 열, 연기, 불꽃감지기에 비해 빠른 반응을 보여 화재를 조기에 감지함으로써 조기 대응으로 인한 피해를 줄일 수 있을 것이다. 본 연구에서는 실물화재시험 자료를 바탕으로 CO감지기의 조기 감시능력을 확인하였다. CO감지기는 화재초기 발생되는 일산화탄소를 감지하므로 대피시간이 많이 필요한 장소(병원 노인요양시설 학교 백화점 등), 침대 폼메트리스 훈소화재 발생장소(호텔침실 기숙사 숙박업소, 병실 등)등에 적응성이 우수할 것으로 분석된다. 최근 설계되는 초고층 건축물 및 주요 시설물 등에서 화재 시뮬레이션과 가상시나리오 유형 분석을 통해 성능위주의 설계가 적용되고 있다. 그만큼 정확하고 신속한 감지가 중요하다 할 수 있다. CO감지기야 말로 그 기대에 가장 부합될 것으로 분석된다.

The recent bridge construction projects is demanded more sophisticated risk management measures and loss forecasts to brace for risk losses from an increase in the trend of bridge construction. This study aims to analyze the risk factors that caused the loss of material in actual bridge construction and to develop a quantified predictive loss model, based on the past record of insurance payment by major domestic insurance companies for bridge construction projects. For the development of quantitative bridge construction loss model, the dependent variable was selected as the loss ratio, i.e., the ratio of insurance payout divided by the total project cost, while the independent variable adopted 1) Technical factors: superstructure type, foundation type, construction method, and bridge length 2) Natural hazards: typhoon and flood 3) Project information: construction period and total project cost. Among the selected independent variables, superstructure type, construction method, and project period were shown to affect the ratio of bridge construction losses. The results of this study can provide government agencies, bridge construction design and construction and insurance companies with the quantitative damage prediction and risk assessment services, using risk indicators and loss prediction functions derived from the findings of this study and can be used as a guideline for future basic bridge risk assessment development research.

The technical expert standing system of our const겨ction industry is operated by the Ministry of Labor subjective national technical qualification law, as the professional engineer, architect and architect-engineer and so on. The construction management(CM) which is introduced on middle 1990 activates a building industry the condition of the essential indispensability for is becoming, is not officially recognized with national qualification to be, that as pending issue it is most urgent, the specialty manpower positivity which is judged as the nostril poop]e for qualification of the civil CM educational institutions has the certification which is a each educational program and a separate way and it is the actual condition which is become accomplished. The problem when as international certification the CMAA which is only it secures a reliability certification which is a CCM and SAVE seeing in the certified which is a CVS, compares in the foreign nation and the CM certification is excessive, it does not secure a reliability and an efficient characteristic to give a confusion to the capital increase lattices which in a condition are, it is mass produced it is a point. It saw from, it observes the capital increase reserve problem point which is a domestic CM and the certification integration which is a report and system anger it leads and with national certified qualification it develops to present the improvement program for, it does to sleep.

While numbers of apartment housing are continually rising in the domestic housing construction industry, apartment contractors are currently developing plane models, upgrading facilities, and relevant technology, and investing much efforts to meet the higher demands of consumers. However, the construction process of apartment housing involves the intricate properties of the construction industry such as materials, workforce, equipment, weather, and unpredictable situations. If any of these factors becomes discordant and results in interference and interruption of the construction process, then defects, both functional and aesthetic, are likely to occur due to errors in the plan of industry organizers and constructors. Therefore, this research identifies the types of defects in an apartment construction project and analyzes their relative importance. Firstly, this research reviews the previous research trends and will reduce the needs of this research. Afterward, defect repair costs corresponding to the different defect types are calculated by applying results of the research and performing frequency analysis on defect types included in 'Tenant preliminary research' on apartments constructed by Company A. As a result of analyzing the importance of defect type, the top six activities, including tile, floor, paper hanging, PL window, cabinetry, and kitchen cabinet, are found to be of high importance, and the top six activities in question need of repair and management of defects first. The results of this study will help establish a plan to initially respond to such problems as refusal to move in and filing a defect suit against delay in repairing defects.

This study concerns especially Choryang-Weagwan which was the largest Japanese House left in Pusan through Chosun Dynasty.Choryang-Waegwan was known to have been jointly constructed by Korean and Japanese carpenters. Therefore, Weagwan was a place for exchange of architectural tradition (special features such as sliding door and straw mat) between Korean and Japan. Judging from this point of view, It is certain that mutual influences helped to shape architecture of Choryang-Weagwan. After establishment Choryang-Weagwan was gradually extended, owing to the prosperity of trade with Japan. But since late 18th century government of Chosun did not give as much care to maintaining Choryang-Weagwan as a result of deteriorating condition of commercial and diplomatic relations with Japan. From the beginning of Choryang-Weagwan construction, Superintendents of the construction were called Hun-do and Byl-cha, who acted as official interpreters as well. And, during construction works, they were called Gamdong-gwan. At the start of construction, Weagwan was built partly in Japanese-style by the carpenters from Tokugawa Shogunate. But as time passed, the participation rate of Japanese carpenters diminished gradually. After 1831, Japanese technician vanished extremely and repairing construction was continued by the Korean

Sudden increase exceeding 30million in the number of smart phone users, and rising interest in the technology of augmented reality, is now trying to combine it with AR technology in other areas very much. The field of cultural heritage, which has been constructed by the Internet and 3D technology, is not unusual and this field is now rapidly changing thanks to the AR technology which can make users experience cultural heritage with high reality. The Palaces in Seoul, however, use fragmentary tools of information - lack of heritage commentators, leaflet, etc, even though the number of visitors is gradually increasing. Therefore, three-dimensional and comprehensive cultural heritage information service is needed with the guidance in the mobile era. This study utilizes the AR technology for building the Deoksugung Tourist Information Service Application(App.) applying the markerless-based recognition technology which is a more advanced tool than the location-based AR technology. This new AR technology can switch perceived real images such as the tablet of the King in the Palace of in the real world, patterns and pedestals into virtual world, which can reproduce the damaged cultural assets as 3D. This also composes photos of the past with the current buildings, which can increase people's interest and absorption of the contents, and helps them understand and be aware of Korean traditional culture and cultural heritage effectively. In addition, convergence between IT new technology, Augmented Reality(AR) and humanities through storytelling based implementation of cultural heritage in smart phone is attempted to demonstrate that there is strength in which augmented reality technique exerts infinite creativity based on actual reality world.

Integrated management of Korea national and environmental planing for sustainable development is suggested, and basic research is needed. In this study, national and regional plans were assessed using 'integrated management index of Korea national planning and environmental planning' to grasp the current status of integrated management on Korea national planning and environmental planning. As a result of the assessment, it was found that both national and regional plans need to improve considering the natural ecology part and water resource and quality part. In addition, it was derived that the detailed contents of the indicator can not be reflected according to the characteristics in the higher-level plan. Therefore, it has been found necessary to include proclamatory contents so as to be able to establish a detailed plan that reflects environmental goals in the lower-level plan.

This study explores fire prevention measures for single-person households on the phenomenon of an increase in single-person households due to changes in the family structure due to low birthrate and aging population, full marriage, non-marriage, separation, bereavement, and returning to farming villages, and increased flexibility in the labor market. The factor that affects the fire of single-person households is the residential environment problem at the structural level. In terms of behavior, there is an increase in fire occurrence due to the rearing of companion animals. In order to prevent fires in single-person households, safety regulations without exceptions are needed to improve the residential environment at the structural level. At the behavioral level, it is necessary to expand the prevention and safety guidance of related organizations. In addition, as a measure to prevent fire caused by companion animals, manufacturers of electric ranges should develop safety devices to prevent fires caused by companion animals, such as an automatic power-off device or power supply using a timer. It can also be an important means to create and distribute promotional videos of measures necessary to safely raise companion animals, or to develop and distribute disaster preparedness programs implemented in virtual reality.
