This study aims to inspect changes of physical expression in surfaces of both building interior and exterior in contemporary architecture. Nowadays society has transformed into more complicated framework with the development of the new media and digital technology in 21 century. Surface's expressivity has been changed with design trend and material development. Although surface study has been mainly concentrated on properties of materials and structure characters, new technology and cultural acceptance enables it extend itself to a new area with various design methods, taking its place as an important contemporary architectural element. Interior surface design is expressed with several unique methods such as optical illusion, surface exposure and spacial depth and volume, and it created dynamic space within the surface itself. In case of exterior surface, whole space seems to be designed to be coordinated with structured optical illusion as well as symbolic expression. Surface's area is extends itself with the stream of the times. This study explored the nature of surfaces with categorizing and comparing them in a various views and methods.

In Korea, starting with the Busan residential-commercial fire in 2010, the frequency of fire expansion in high-rise buildings has been continuously increasing. In the case of such large-scale fires, most of the fires generated from the inside tend to expand to the upper floors by riding the exterior material or exterior wall panels through the process of being ejected to the outside. It has been revised so that combustible exterior materials cannot be used in buildings. However, due to the legal fluoride level, the fire risk of high-rise buildings is still high, such as the case of a 33-story residential-commercial fire in Ulsan. In order to prevent such fire expansion, it is considered that it is necessary to first understand the nature of the fire occurring inside and the mechanism of the fire expansion in the upper floor. The purpose of this study is to propose improvements in domestic fire safety design through a review of existing literature to prevent fire expansion of high-rise buildings.

This study surveys the usage and satisfaction of car seat covers, analyzes the satisfaction and luxuriousness of materials used and provides basic data on optimum car seat covers that improve consumer satisfaction, stability, and comfort, while driving. The survey was conducted on 150 people in their 20s to 60s with a car. Consequently, achromatic colored car seat covers were used most and the satisfaction with black was very high. Interior & exterior harmony and the pursued car image were considered important, this consumer psychology impacted the color selection for car seat covers. The satisfaction reasons were different according to materials. Genuine leather was highly regarded in interior & exterior harmony (20.8%), excellent seat sensation (17.7%), excellent tactile sensation (11.5%), and luxuriousness (8.5%). For artificial leather, interior & exterior harmony (16.5%) and easiness of stain removal (13.6%) was rated high and fabric had excellent seat sensation (12.3%) and economics (10.8%). The material, heated and ventilated device affected car seat cover satisfaction. The luxurious image of car seat covers was pursed and was perceived mainly with a sense of sight. Luxury car seat covers were mainly created with materials. Genuine leather and black car seat covers increased luxuriousness. For car seat covers, those with flexibility, excellent compressive elasticity, and thickness were perceived as luxurious.

EIFS system has the merit of low construction cost and shortening of construction period by easy-to-construct. For such reasons as mentioned above, it has been using across the board such as residential building, school, officetel, building remodeling and so on. It, however, has a drawback of generating plenty of combustible gases from styrofoam which is main material of it. In this regard, measures to prevent losses of life from combustible gases are needed urgently as fires on residential buildings applied EIFS caused human casualties resulted from combustible gases. With respect to the above, this study will analyze the risk of fires on residential facilities, such as multi-family apartment houses, schools and other buildings, applied EIFS which is the most frequently used as material of exterior wall and suggest countermeasure of it.

In this research, exterior material combustion experiment was really tested to evaluate fire risks of aluminium complex panel which is used a lot for building exterior material. As a result, We saw fast fire spreading of aluminium complex panel. The reason is polyethylene in aluminum complex panel combust spreading fast fire flame vertically. In this test, the highest heat release rate of aluminum complex panel was 1,144 kW and surface temperature which is measured by thermocouple went up to more than $903.3^{\circ}C$, that temperature is quite a higher than $660^{\circ}C$ which is aluminum melting temperature. So, fire of aluminum complex panel can be evaluated to give us severe damage both by fast fire spreading vertically and by fire spreading through openings internally. These results from real experiment will be able to use to predict fire spreading of aluminum complex panel by comparing to modeling materialization of aluminum complex panel in the future.

The long term plan for apartment housing has a important role to make a decision making whether a repair work should be done or not. But, items for repair works are so various that field workers could not understand the context or plan the repair cost and time. These difficulties are drawn from the number of repair items, duplicated application and meaning, new material application and technology time-gap. Therefore, it needs to change or coordinate the repair items to improve the repair condition, reflecting the current material level or repair technologies. In this paper, it aimed at coordination of the repair items through the repair recording sheet which was surveyed in 22 metropolitan areas of Seoul, conducted between 2011 and 2014. The surveyed data are classified into six categories such as building exterior, building interior and so on, according to long term repair plan and the number of data are 1,918. It analyzed the appearing word for repair-concerned and compared the existing items of the long term plan. Items of building exterior are proposed as roof, exterior wall and painting. Building interior has a little meaning to propose the repair items. The water supply facilities are proper to keep the existing repair items. Items of the outdoor facilities could not need a sign board, drainage root and PVC sheath. Through this study, we can coordinate the repair items in apartment and provide the repair item and cost level.

Grenfell Tower was renovated in 2014 and 2016 at a high cost to replace the exterior materials, windows and co-heating facilities of the building. The exterior materials used during the repair work were sandwich panels filled with polyethylene and plastic, which were expanded on the aluminum metal surface. It is a product called Celotex RS 5000, a low-resolution but inexpensive repair material, and is currently an external material that cannot be used in high-rise buildings. Similar domestic fire cases began to focus social attention on the safety of high-rise buildings through the Busan Residential Complex Fire (2010), Uijeongbu Urban Living Housing Fire (2015), and Ulsan Residential Complex Fire (2020), and residents' safety concerns are increasing. In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. Therefore, the purpose of this study is to examine the status of fire damage caused by domestic and foreign eruptions, domestic and international research status and related regulations on external materials and windows starting from the Grenfell Tower fire in England.
