The purpose of this study is to find building and psychological variables which affect occupants’ IEQ (Indoor environment quality) satisfaction in office buildings. The results showed that (1) occupants’ IEQ satisfaction increased with behavior adjustability, satisfaction with interior design, and level of ensuring privacy. (2) Occupants’ satisfaction with each physical condition (thermal, noise, lighting, indoor air quality) decreased when building scale is too large. Building scale also had a significant effect on behavior adjustability. (3) The linear relationship between all psychological variables and IEQ satisfaction was proved. (4) As IEQ satisfaction (thermal, noise, lighting, indoor air quality) increased,overall workspace satisfaction did also increase. Especially, among four IEQ satisfactions, noise satisfaction was the most effective factor on overall workspace satisfaction.

ON JANUARY 14, 2012, INCUMBENT PRESIDENT MA YING-JEOU OF THE Kuomintang (KMT, or Nationalist Party) on Taiwan was re elected. As President Ma embarks on his second term, the question of whether he will negotiate and sign a military mutual confidencebuilding mechanism with mainland China has become an issue of concern for the public on both sides of the Taiwan Strait. The issue also has potential regional security implications. In recent years, the leaders of Taiwan and mainland China have often expressed goodwill and proposed a number of critical initiatives that would bring about a new dawn in cross-strait relations. These initiatives include the signing of peace agreements as well as negotiations on a military mutual confidence-building mechanism. Nonetheless, many difficulties must be overcome to achieve what the two sides envision. We examine these issues from the perspective of the leaders of the respective nations by presenting four variables that could potentially influence the progress of discussion. Leaders need to understand the potential outcomes in advance so as to formulate strategies to counter a negative turn of events that could derail the initiatives. If they can do so, the strategic objective of a win-win situation may be fully accomplished, ensuring the preservation of lasting peace and stability across the Taiwan Strait and the Asia-Pacific region as a whole.

본 연구는 경매 시장에서 오피스의 낙찰가율이라는 시계열자료를 이용한 요인분석 모형을 구축하여 부동산 경매시장에서 오피스 낙찰가율에 미치는 영향요인 중에서 거시경제변수가 어떠한 영향을 미치는 여부와 시간의 흐름에 따른 낙찰가율 영향요인의 변화특성을 분석하고자 하였다. 분석결과 오피스 낙찰가율이 소비자물가지수, 총통화량, 경제성장률에 민감하게 반응한다는 사실이 확인되었고, 이들 변수들을 경매시장에서 오피스 건물에 대한 투자의사결정 요인으로 고려할 필요가 있다는 점이다. 또한 종합주가지수와 이자율은 오피스 낙찰가율에 영향을 미치는 요인으로 보기 어렵다는 결과가 도출되었는데, 이는 경매시장에서 오피스 건물에 대한 투자는 주식, 투자금융상품과의 상관관계가 낮다는 것을 나타내므로, 경매시장에서 오피스 건물의 투자는 주식 내지 투자금융상품과의 분산투자를 통해 포트폴리오의 위험을 낮추고 수익을 증대시키는 투자대상으로서의 활용성이 높다는 점이다.

This study suggests a genetic algorithm-based partial least squares (GA-based PLS) method to select the design variables for building a usability model. The GA-based PLS uses a genetic algorithm to minimize the root-mean-squared error of a partial least square regression model. A multiple linear regression method is applied to build a usability model that contains the variables seleded by the GA-based PLS. The performance of the usability model turned out to be generally better than that of the previous usability models using other variable selection methods such as expert rating, principal component analysis, cluster analysis, and partial least squares. Furthermore, the model performance was drastically improved by supplementing the category type variables selected by the GA-based PLS in the usability model. It is recommended that the GA-based PLS be applied to the variable selection for developing a usability model.

This study is to find out the determinants of the net operating income from office building, which may be said to be the profit for a company, estimate the floor space which maximizes or minimizes the net operation income and also find out the effect of the type of ownership on the net operating income. The result of the regression analysis for net operating income for office showed that the income is dependent on the building area, number of story, age and location of the building. According to the corporate profit maximization theory, it was estimated that the net operating income for the office building would be the smallest when the gross area is 10,886㎡ while it is the largest with 44,606㎡. In addition, the type of ownership of office building was analyzed as the types of ownerships get diversified. It showed that the average net operating income earned by the investing organization is bigger than those earned by large companies. It is because the effective gross income for the investment organization is higher than for large corporations. This study has meanings as it handled both revenues and expenses of office buildings compared to the previous studies, derived the gross area which maximizes the net operating income and take into consideration type of ownership for the difference in net operating income. This study has its limitation as the precaution is required in applying the result to the study of offices located all around the nation. But, if the result is adopted for regional application, the difference of net operating income depending on the type of ownership would be more clear.

This paper presents an experimental study on the performance of the active damper device by feedback variables. The damper is a mass-typed active device, which exerts the inertia control force on the building by AC servo motor. The control performance is experimentally analyzed considering the building response and the control force. It is found that the building response is greatly reduced by mass-typed device under the resonant and earthquake loading. Also, the experimental results show that the velocity feedback reduces the building responses with the smallest amount of control force than any other feedback variables.

해체공사 전체기간 동안 감리원 상주 배치가 의무화되면서, 감리대가 산정 방법으로 기존 활용되던 공사비요율방식 외 실비가산정액방식이 도입되었다. 그러나, 해체공사비에 따라 정해지는 비율을 곱하여 산정되는 공사비요율방식과 달리 실비가산정액방식은 건축물 규모, 해체공사 계획, 주변 환경 등을 고려하여 건축관계자, 감리자 간 협의에 따라 감리대가가 결정되므로 감리자에 따라 산정된 금액의 편차가 존재할 수 있다, 이에, 본 연구에서는 최근 4년간의 서울시 해체공사 감리 계약 데이터를 기반으로 건축물 규모뿐 아니라 해체공사 정보를 활용하여 감리대가와의 상관관계 분석을 수행하고 상관성이 높은 주요 영향변수를 도출하였다. 이후 도출한 주요 영향변수를 활용하여 감리대가의 적정수준을 통계적으로 평가할 수 있는 간편 계산식을 제안하고 추정 성능을 검증하였다.

With full-time on-site supervision throughout the entire duration fo dismantlement, a method has been introduced to allow the use of the cost-plus-fixed-fee method in addition to the previously used percentage-of-construction-cost method for calculating supervision fees. Unlike the percentage-of-construction-cost method, which applies rate depending on cost of dismantlement works, the cost-plus-fixed-fee method permits variations in supervision fees through consultations among stakeholders, with such variations reflecting building scale, dismantlement plan, etc. Therefore, this study perform the correlation analysis between supervision fees and variables by utilizing dismantlement supervision contract data from Seoul over the past four years. Based on these main variables with high correlation to supervision fees, a simplified estimation formula is proposed to statistically evaluate appropriate supervision fee levels, and its predictive performance is evaluated.

It has been interested in appling smart window system to buildings in order to control solar transmittance by active way. The performance of control strategies on the smart window system, especially electrochormic window (ECW), have not fully evaluated in the perspective of building energy consumption. The presented article provides potential control parameters and logics to operate ECW. It also evaluates building energy performance by the developed ECW controls conducting annual building energy simulation for a medium size office building model. Five control parameters are derived from time scheduling (SPC), solar irradiance (IRD), outdoor air temperature (OAT), cooling demand (CMD), and room air temperature(RAT). Each control parameter has ranges or target values to activate ECW operation. The result shows the control methods can avoid solar transmittance by 90% thorough South, East, and West in the highest solar radiation day in Inchoen, Korea. ECW operation can reduce cooling equipment sizing by 20% in approximation and save annual HVAC energy consumption ranges from 11.22% to 20.70% by the control methods. The RAT would be the most effective control parameter from this study because it outperforms other parameters on annual HVAC energy saving and investment of system installation.

경쟁이 심화되고 시장이 포화되면서 관계마케팅에 대한 관심은 증대하고 있다. 그런데 많은 연구들이 모든 소비자가 관계지향적인 성향을 가지고 있는 것은 아니라는 점을 지적하고 있다. 그렇지만 어떠한 성향을 가진 소비자가 관계지향적인 성향을 가지고 있는가에 대한 본격적인 연구는 이루어지지 않았다. 본 연구는 영업사원이 제공하는 관계적 혜택(확신 혜택 및 사회적 혜택)에 대한 중요성 지각을 매개 변수로 소비자의 어떠한 내재적 특성이 영업사원과의 관계구축 의도에 영향을 미치는가를 분석하고 있다. 본 연구의 가설에서 확신 혜택에 대한 중요성 지각에 영향을 미칠 수 있는 소비자의 내재적 특성으로 위험감수 성향, 다양성추구 성향, 제품지식, 타인 신뢰 성향 등의 변수를 제시하였으며, 사회적 혜택에 대한 중요성 지각에 영향을 미칠 수 있는 소비자의 내재적 특성으로 대인성향, 가격민감도, 타인 신뢰 성향 등의 변수를 제시하였다. 실제로 영업사원과의 거래를 통해 증권거래를 하고 있는 소비자 396명으로부터 자료를 수집하였다. 구조방정식 모델을 이용하여 분석한 결과, 소비자의 내재적 특성과 영업사원과의 관계 구축 의도의 인과관계에 있어서 관계적 혜택에 대한 중요성 지각이 매개 변수로서의 역할을 하고 있는 것으로 나타났다. 또한 소비자의 내재적 특성 가운데 다양성 추구 성향은 확신 혜택에 대한 중요성 지각에 음의 영향을 미치는 것으로 분석되었으며, 타인 신뢰 성향은 확신 혜택 및 사회적 혜택 모두의 중요성 지각에 양의 영향을 미치는 것으로 분석되었다. 또한 가격 민감도는 가설에서 설정된 방향과는 다르게 사회적 혜택의 중요성 지각에 양의 영향을 미치는 것으로 분석되었다.

As the competition intensifies and the market matures, marketers are more and more concerned with the relationship marketing. Many of the previous researches have pointed out that not all of the consumers are relationship-oriented. But none of the previous research has systematically investigated this issue. * Professor, Department of Business Administration, College of Business Administration, Kyung Hee University(cwpark@khu.ac.kr) This research investigated the relationship among the three concepts: consumers' intrinsic characteristics, perceived importance of relational benefits, and relationship building intention with the salesperson. In this research the perceived importance of relational benefits is treated as mediating variable in the relationship between consumers' intrinsic characteristics and relationship building intention with the salesperson. The conceptual model in this study can be depicted as follows. From the consumers' perspective relational benefits can be defined as "the additional benefits consumers can receive in addition to core services through the long-term relationship with the service provider." And in this study two kinds of relational benefits are adopted by reviewing the previous research: confidence benefits and social benefits. Relational benefit received from the salesperson is very important to predict consumers' relationship building intention with the salesperson. The more relational benefits consumer wants from the salesperson, the more relationship building intention he/she has. From this point two hypotheses are derived as follows. Hypothesis 1: As the perceived importance of confidence benefit from the salesperson increases, the relationship building intention with the salesperson increases. Hypothesis 2: As the perceived importance of social benefit from the salesperson increases, the relationship building intention with the salesperson increases. In this study four individual characteristics(risk taking tendency, variety-seeking tendency, product knowledge, trust orientation) are hypothesized to influence the perceived importance of confidence benefits from the salesperson. And three individual characteristics(interpersonal orientation, price consciousness, trust orientation) are hypothesized to influence the perceived importance of social benefits from the salesperson. These 7 hypotheses are as follows. Hypothesis 3: As the risk taking tendency increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 4: As the variety-seeking tendency increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 5: As the product knowledge increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 6: As the trust orientation increases, the perceived importance of confidence benefits from the salesperson increases. Hypothesis 7: As the interpersonal orientation increases, the perceived importance of social benefits from the salesperson increases. Hypothesis 8: As the price consciousness increases, the perceived importance of social benefits from the salesperson decreases. Hypothesis 9: As the trust orientation increases, the perceived importance of social benefits from the salesperson increases. The whole model in this study can be depicted as follows: Data were collected from the 396 consumers who actually trade stocks through the salesperson and were analyzed using structural equation model. The analysis results show that consumers' perceived importance of relational benefits(confidence benefit and social benefit) play the roles of mediating variables in the causal relationship between consumers' inherent characteristics and their relationship building intention with the salesperson. As for the individual characteristics, the influences of variety-seeking tende...
