In the early stages of a construction project, the most important thing is to predict construction costs in a rational way. For this reason, many studies have been performed on the estimation of construction costs for apartment housing and office buildings at early stage using artificial intelligence, statistics, and the like. In this study, cost data held by a provincial Office of Education on elementary schools constructed from 2004 to 2007 were used to compare the multiple regression model with an artificial neural network model. A total of 96 historical data were classified into 76 historical data for constructing models and 20 historical data for comparing the constructed regression model with the artificial neural network model. The results of an analysis of predicted construction costs were that the error rate of the artificial neural network model is lower than that of the multiple regression model.

Although recently revised building code requires 15~20% increased thermal insulation performance for window systems, since the code is focusing on winter heat loss, it is not satisfactory to contribute on reducing rapidly rising cooling load in summer. Window systems have great impact on building heat gain and loss. Therefore technological development for window system specialized in shading solar gain in summer is an urgent matter. This study evaluates the performance of sun shading and thermal insulation for blind integrated window system. Also, computer simulation evaluates the effect of heating and cooling energy consumption reduction for an individual unit(floor area of $85m^2$) of a multi-family housing. Physibel Voltra, a heat transfer analysis software, was used to analyse the effect of energy consumption reduction, and the energy load was converted to the cost to compare the actual effect of economical benefit.

The purpose of this study was to investigate the perception of and preferences for traditional seasonal foods in Deagu & Gyeongbuk. According to surveys, females (51.2%) demonstrated a higher preference level than males (48.8%), and that for 'married' subjects was highest. Most subjects were classified as 'nuclear family', and 55.0% lived in apartment housing. The reason they experienced or gained knowledge of Korean seasonal foods was parents, which accounted for 64.4%. Reasons for liking Korean traditional drinks was 'traditional food', which scored the highest at 62.8%, followed by 'seasonal food' at 30.4%. The most common reason for disliking Korean drinks was 'lack of information'. The perception of and preferences for seasonal foods were 'rice cake soup', which scored the highest (4.85 points), followed by 'Ginseng chicken soup' (4.70 points). As a result, popularization of traditional seasonal food was based on three factors: modernization, simplicity, and awareness, which significantly influence the preference for Korean traditional seasonal foods.

지금까지 우리는 건물분야에서의 합리적인 에너지 사용을 위하여 건물외피의 단열성능을 향상시킴으로써 열손실을 줄이려는 데에 주력하여 왔으며, 침기로 인한 열손실을 줄이려는 노력은 상대적으로 미흡하였다. 그러나, 침기로 인한 난방에너지의 소비가 상당량에 이르는 것으로 조사됨으로써 재실형태에 따라 최소환기기준을 만족시키면서 침기에 의한 불필요한 에너지의 손실을 줄이려는 노력이 매우 유효한 것으로 평가되고 있다. 실제로 침기에 의한 불필요한 에너지의 낭비가 얼마나 되는가를 평가하기 위해서는, 건물에서의 침기율을 정확하게 측정할 수 있는 방법이 전제되어야 한다. 본 연구에서는 감압/가압법의 일종인 Blower Door System을 사용하여 공동주택에서의 기밀성능을 측정, 평가함은 물론 측정결과를 토대로 합리적인 수준까지 기밀화할 경우 난방에너지의 절약가능성에 대하여 추정하였다.

Most hot water heating valves for apartments are constant-flow types, which limit the flow rate through an individual household for even distribution of heating water to other households. The constant-flow type is implemented by an on-off control. As a result, heating water is supplied intermittently and hence, indoor air temperature also fluctuates. Returning water temperature is also high, which reduces energy efficiency. To implement continuous feedback control, the indoor temperature dynamics was simulated to fit a measured temperature history by a state-of-the-art physical model. From the model, it was found that the most important disturbance is outdoor temperature and its effect on indoor temperature lasts about an hour. To cope with the slow response and the significant disturbance, a prediction control with proportional feedback is proposed. The control was found to be successful in implementing continuous heating water flow and improved indoor temperature control.
