종이가 인류의 생활에 미치는 비중은 정보의 전달을 제 l의 목적으로 사용되고 있는 인쇄용 지와 필기용지가 차지하는 것이 가장 크다. 정보전달의 매개로 사용되는 종이의 용도 이외 의 것을 살펴보면 전사지, 감압.감열지, 절연지,OMR지, 항공권지, 벽지 등과 같은 특수지와 기능지가 있다. 특히 벽지는 다양한 문양과 색감으로 인간의 미적 감각과 정신적 안정감에 미치는 영향이 크다. 벽지의 기능은 여러 가지의 목적으로 우리들의 실생활에 있어서 없어서는 안될 중요한 건축 재료로서 사용되고 있다. 가장 중요한 벽지의 목적은 앞서 언급한 바와 같이 미려한 색상과 다양한 디자인으로 도안.인쇄 및 발포 처리된 벽지를 사용하여 단순한 벽면을 개인의 취향 에 맞게 함으로써 심리적 안정감을 가져옴과 동시에 미적 가치를 증가 시켜 문화 수준의 향 상에도 영향을 미치는 것으로 알려져 있다. 그러나 종이 벽지와 종이 벽지 원지를 기저로 하여 제조된 발포 벽지는 인화성이 강하기 때 문에 이들에 대한 적절한 난연 처리가 요구 되고 있다. 매년 발생되는 다양한 형태의 화재 는 돌이킬 수 없는 인명과 재산의 손실로 귀결되어 각별한 주의가 요구되기 때문에 주거공 간과 대중의 군집이 많이 이루어지는 공공장소에서의 난연 처리된 벽지 사용에 대한 중요성 이 나날이 그 강도를 더 해가고 있는 실정이다. 난연 처리된 벽지는 통상적인 벽지에 비하 여 제조 원가의 상승에 따라 가격이 비싸기 때문에 일반인들에게 있어서 그 사용은 주목할 정도로 증가되지 못하고 있으나, 생활 수준이 향상 될수록 안전에 대한 의식 강화와 정부의 노력으로 인하여 그 사용량은 크게 늘어날 것으로 기대된다. 따라서 본 연구에서는 종이의 제조에 사용되는 원지의 충전제 종류와 양 그리고 난연 처리 된 폴리에스테르 섬유의 혼합을 달리하여 제조된 원지를 사용하여 난연 처려한 후 이들의 인화 특성에 대해 고찰 함으로써 보다 향상된 성능을 발휘 할 수 있는 난연 벽지의 제조와 개발에 보탬이 되고자 하였다.

Modern architecture and design show experiments that practice exchange and convergence with other genres through expansive thinking. This study aims to propose the use of graphic skins as a means of dematerializing and invisiblizing expressions of architecture. The method of realizing 'invisible architecture' can be largely divided into methods that use materials that manipulate light and graphic approaches based on trickery techniques. The exterior wall graphic of the special stage in Seoul Plaza can be said to be an attempt of dematerialization to make the building structure light and transparent, and a case to propose the role of super graphics to maintain the identity of the original place by erasing disharmonious elements from the field of view. It is expected that the graphic skin will be used as a powerful means of expression in the era of 'invisible architecture' as an effective camouflage method and media beyond the means of decorating the exterior walls of the completed facilities.

This study aims to find out the present conditions of pilotis space, and the usage and requests of it by residents as to suggest the direction in planning pilotis spaces in apartment housing. This study selected six apartment complexes, and conducted case-studies and surveys of them. The study findings are as follows. 1) The types of pilotis spaces of the apartment housing can be categorized into an entry type, a community type, a recreational type, a bicycle storage type, a pedestrian passage type, a parking type, and a visual passage type. As a result of studying the present conditions, pilotis spaces of a recreational type were the most, and a community type and a parking type were not found. It was found that diverse types of pilotis spaces need to be planned in consideration of the characteristics of an apartment complex and its residents. 2) As for residents' time spent in using the pilotis space, they spent little time. This can be attributed to the fact that most pilotis spaces were designed only with simple flat benches, and gazebos, which seemingly failed to draw residents' attention. Therefore, the spaces need to be planned for diverse purposes after examining residents' needs, which can include indoor exercise equipments and children's play facilities. 3) Regarding the residents' requests about pilotis spaces in the apartment housing, the most widely requested was using it as a community space. Also, many requested to use it as a library, and a children's play space. Therefore, it needs to be considered to plan the pilotis space for providing diverse programs.

This study has analyzed the scanning path algorithm shown at the process of exploring spatial information through an observation experiment with the object of lobby in subway station. In the estimation of observation time by section, the frequency of scanning type was found to increase as the observation time got longer, which makes it possible that the longer the observation lasts the more the observation interruptions occur. In addition, the observation slipped out of the range of imaging when any fatigue was caused from the observation or the more active exploration took place. Furthermore, when the trend line was employed for the examination of the changes to the scanning type by time section, "concentration" "diagonal or vertical" showed a sharp and a gentle increases along with the increase of time section respectively, while "circulation. combination, horizontal" showed a reduction. The observation data of the subjects observing a space include various visual information. The analysis of the scanning type found at "attention concentration" enabled to draw this significant conclusion. The features of increase and decrease of scanning types can be a fundamental data for understanding the scanning tendency by time.

Mirror is a physical reflective surface, typically of glass coated with a metal amalgam, and it is to reflect an image clearly. They are available everywhere anytime and become an essential tool for us to observe our faces and appearances. With the advent of modern software technology, we are motivated to enhance the reflection capability of mirrors with the convenience and intelligence of realtime processing, microservices, and machine learning. In this paper, we present a development of Digital Mirror System that provides the realtime reflection functionality as mirror while providing additional convenience and intelligence including personal information retrieval, public information retrieval, appearance age detection, and emotion detection. Moreover, it provides a multi-model user interface of touch-based, voice-based, and gesture-based. We present our design and discuss how it can be implemented with current technology to deliver the realtime mirror reflection while providing useful information and machine learning intelligence.

It is needed to regenerate declined industrial districts in downtown area through to invite new industry and to improve urban environment. The purpose of this paper was to make suggestions on the urban regeneration for the districts. I have taken a literature research and a site analysis with cases of 'the South Lake Union' in Seattle and 'Pearl District' in Portland, USA. The result of the analysis was as follows: (1) The land use was changed to mixed use of business-commerce-recreation. The building use was changed to facilities for work, play and live. (2) Infrastructures were improved for user oriented facilities such as pedestrian friendly street, public parks & open spaces, public transportation system, and life supporting facilities. (3) The place identity was enhanced through the preservation of urban structure-tissues, renovation of existing buildings, and preservation of historical heritages.

Fifteen years after the modernization of traditional markets, commercial facilities and some 1,000 markets across the country contacted arcade operators, there are no specific guidelines on installation standards, exact guidelines for public facilities, and guidelines on law, maintenance and management yet. Therefore, it is necessary to derive a plan that reflects the mindset of the market project and the users as basic planning data for making arcade remodeling of traditional markets more advanced. As a research method, case studies and surveys were conducted and the details are as follows. Through the case study, this study drew suggestions that were available and needed in Korea on the planning plan of arcade space in the developed traditional market and conducted user preference. The survey participants are 150 users of Daegu seomun market. In addition, the survey contents are approached with the concept of remodeling remuneration, so the total number of questions is 47 including 'accessibility', 'comfort', 'openness', 'safety' and 'integrity', which are five elements of the arcade plan. The survey method assessed the importance and satisfaction of each questionnaire on a 5-point scale, and the survey results were compared with technical statistics and means using the SPSS statistics package. The results of user awareness and image survey, in which the installation and remodeling of the ventilation system of the crosshairs are mentioned in the event of fire or in the case of daily ventilation, are important factors in safety. The user-conscious survey, analyzed in 'integrity', indicates that the use of multi-purpose space is required, and that the layout of street stalls and parking and user movements should be integrated. Mac of this study is going to present direction of remodeling plan and behavior analysis by analyzing user preference data for advanced remodeling of arcade in traditional markets.

The police substation includes work spaces for civil services, interviews, and meetings, etc, and private spaces for rest, showers and cafeterias and so on. Since a large number of rooms for each function should be installed in a relatively small building, it is important to develop an area standard for efficient space organization in consideration of the functional characteristics and usage patterns of each space. The purpose of this study is to suggest the way for improving the area standards for spaces in police substation based on the results of existing standards analysis and case study. For this objective, architectural documents of 161 police substations built after 2013 in Korea were comparatively analyzed. Sixteen of these facilities were selected for field survey and investigated how the workspace and private area were organized and used. The results of investigation showed that there were a number of problematic cases, such as spaces not installed or insufficient, spaces used for two or more functions, spaces installed even though they are not included in the standards. It was mainly due to the fact that several important spaces which had been installed in most police substations were not included in the existing standards. The ways for improvement were suggested like following four points: (1) Modifying the criteria for classifying facility size, (2) Modifying the lists of the required spaces, (3) Specifying the basis of calculation for each space in detail, and (4) Differentiating the way to organize spaces according to the facility size.
