홍수로 인한 주거건물의 경제적 피해는 침수심, 침수기간, 유속 등의 재난인자와 제내지에 노출된 사회 경제적 인자들 간의 복합적인 작용으로 발생하지만, 다차원홍수피해산정법을 비롯한 대부분의 모형에서는 침수심 만을 고려하고 있다. 최근 국외에서는 홍수피해와 영향인자 간의 관계를 규명하여 홍수피해액 평가 시 침수심 외 중요한 기타 인자를 고려하는 연구가 시도된 바 있으나, 국내에서는 이것과 관련한 연구가 그동안 거의 진행된 바 없다. 이에 본 연구에서는 주거건물을 대상으로 홍수피해 영향인자를 규명하고자 과거 피해지역을 대상으로 설문조사를 시행하여 자료를 수집하였으며, 설문조사에 앞서 사전 문헌연구를 바탕으로 수리/수문학적 인자, 건물특성인자, 예방인자, 조기경보/조치인자, 사회 경제적인자, 피해인자로 설문항목을 크게 구분하여 설문지를 설계하였다. 설문조사는 2014년 8월에 광범위하게 피해가 발생한 부산광역시를 대상으로 1대1면접조사 방식으로 진행하였으며, 수집된 자료로부터 상관분석, 데이터마이닝 등의 통계적 분석을 통해 침수심 외 몇몇 중요한 피해액 영향인자를 확인할 수 있었다. 본 연구를 통해 평가된 홍수피해 영향인자는 향후 홍수피해평가 모델을 개발하거나 홍수피해저감을 위한 세부적인 계획에 기여할 것으로 기대된다.

Predicting how much energy to use is an important issue in society. However, it is more difficult to capture the usage characteristics of residential buildings than other buildings. This paper provides time series analysis methods for electricity consumption in a residential building. Temperature is closely related to electricity demand. An error correction model, which is a method of adjusting the error with time, is applied when a cointegration relation is established between variables. Therefore, we analyze data via ECMs with consideration of the temperature effect.

This study analyzed the importance of factors according to the investor's perspective through a survey of residential real estate experts using AHP and fuzzy theory. Analysis results showed that rent, profitability, traffic accessibility, commercial and infrastructure, and financial regulation are important in common. By expert group, financial and credit groups cited profitability, rent, traffic accessibility, supply and tax benefits, construction and development groups cited traffic accessibility, rent, direct access, profitability, commercial area and infrastructure, and appraisal and evaluation groups cited rent, profitability, transportation accessibility, financial regulation and supply as the most important factors. This showed that it had a preference characteristic that was associated with work. In other words, it focuses most on the financial perspective in investment characteristics, and it values convenience such as accessibility to transportation and commercial districts and infrastructure as its location characteristics. In addition, it was found that easing financial regulations in the market is important to expand investment in real estate. This study aims to help the business feasibility analysis of residential property developers and rational decision-making of general investors who are consumers, taking into account the various perspectives of the expert group.

Residential environment is not only the physical aspects affected by the unique characteristics of the residents, social, economic, cultural, etc. are closely related to many environmental factors. This research is based on choice attribute theory that substantially explains how housing choice attributes affect loyalty via image, perceived value in Secho. This paper investigate empirically relationship between selection properties of residential environment and loyalty, moderating effect of image and perceived value. Results were computed using SPSS 20.0 statistical analysis programs. The results are summarized as follows. First, The elements of choice attribute are divided into six factor, such as regional reputation, green environment, convenience, property value, safety, housing status. In the results of the analyses, housing choice properties gives a positive influence to the loyalty. Second, testing its mediating role, I use the three regression equation models by Baron and Kenny. When the mediator effect of image, perceived value was represented, the effect of image and perceived value was statistically significant. Thus, the mediating role of image and perceived value was supported. It means the higher image and perceived value can enhance loyalty of Secho.

Population growth in Korea is slowing down, and the ratio of 1~2 person households has exceeded 53.3% of the total. And in the future, it is becoming more important how to accommodate as proper planning in residential areas. In this paper, we examine whether the existing district unit plans respond appropriately to the trend of the increase in small-sized housing, and we propose improvement plans for elements of the district unit plan and measures to enhance its applicability in response to small-sized housing. To do this, we analyzed the guidelines and contents of the district unit plans related to small-sized housing in recent 6 residential sites, and derived problems and improvements through literature review and expert consultation. As a result of the study, we proposed the items that need to be reflected in the district unit plan related to various housing type for one person household. And planning elements related to households, housing site, building layout, and architectural shape and appearance were also proposed, which were suitable for single-person households, such as small-sized communal housing, share-house, and single-person housing. It also suggested that single-person households should be considered for housing characteristics, including introduction of auxiliary welfare facilities such as unmanned delivery box and guest houses, and exclusion of low-demand auxiliary welfare facilities such as kindergartens. The suggested content can be used to make guidelines for small-sized housing in district unit plan.

The purpose of this paper is to find out the needs of housing contents in highschool Home Economics among students. The 105 housing contents and topics were chosen from the 3 textbooks and related references. The number of 516 questionnaire from 8 areas were used to analyze. Analyses indicated that respondents were more likely to favor Home Economics subject and one out of five wanted to select it. Average needs of the housing contents was above middle(3.4) and these was a little difference among 3 middle units in housing. The most needed unit was housing design. There was a more wide difference in 19 small units than in middle ones, ranged $3.00\sim3.91$. Individual contents showed the most variousness in needs from 2.89 to 4.30 in the middle unit of housing and environments, 3.00 to 4.01 in housing design, and 2.68 to 3.91 in housing management. The needs of additional contents were about the same as those textbook contents and it indicated that new textbook needs to adopt the newly demanded housing contents. Some of individual, family, and environmental characteristics were significantly related to the students needs. The higher positive attitude such as favor, interest, and selecting of the subject was related to the higher needs of housing contents. Residential areas and neighboring were also related to most of the needs of individual housing contents.

The purpose of this research is to analyze characteristics and related factors of IAQ (Indoor Air Quality) in newly built wooden houses by measuring pre and post occupancy. The subjects were five wooden houses which were built with similar materials and completed from July to December 2013. Measuring factors were TVOC, HCHO, PM10, $CO_2$, CO, indoor temperature, and relative humidity. As the result of pre occupancy measuring, the houses that revealed the lowest TVOC concentration or HCHO concentration were satisfied with "the standard for newly built apartment houses". Therefore, IAQ by the wooden structures is considered to be in good condition. However, in cases of partial value exceeded the standard, the reason is analyzed to be the materials of molding, wrapping doors, built-in closet, or kitchen furniture, etc. rather than structure materials. Most PM10 concentration level showed slightly below "the standard for occupied multi-use facilities". Remaining of construction dust was considered to be the reason. As the result of post occupancy measuring, every value except of one subject's TVOC concentration was lower than pre occupancy, explaining the importance of natural ventilation.

To cope with rapidly increasing crimes, the Smart-home system has become common to minimize and prevent crimes in the residential space. Accordingly, the interest on the security-related Smart-home system is also increasing. First is the establishment of Smart-home security standard. At present, the Smart-home security systems are implemented by individual policies of construction companies or by the requirement of residents. Each construction company has their own characteristics in the Smart-home security system; while there is no standardized system. Second is the introduction of Smart-home security certificate system. Like people have certificates, now the residential spaces may also need certificates. A certificate system that represents the performance of residential spaces cannot be an absolute criterion in the evaluation of apartment quality, however, it can be a basic requirement for the convenient residential environment and policies being implemented by the government. If a certificate system would be introduced, construction companies will compete with each other to provide with better security system and apartment operation companies will hire more specialized security personnel in order to get higher certificates. Consequently, better security of residential space will be secured. It is also required to develop and establish response measures by studying the key changes and trends of Smart-home security system. The advance in mechanical security devices will bring about more changes in the future. Therefore, more various in-depth studies are required on the basic specifications of security system in the residential spaces.
