The new paradigm called 'Low Carbon Green Growth' involved in reducing greenhouse gas is on the rise as a critical issue worldwide. The essential of Kyoto protocol issued in 1997 is to achieve the sustainable economic growth environments by converting existing production system to eco-friendly one. The protocol imposes the liability to reduce greenhouse gas to the countries joined to it. The paradigm is directly involved in the energy consumption and environmental pollution caused by construction activities. Value Engineering which are mainly applied in the design phase in practice is a measure to improve the value of a constructed facility by analyzing and/or appraising the functions and costs of it. However, an appropriate method which assesses eco-friendliness of constructed facility has not been propose by researchers. This paper proposes a method which assesses the performance involved in eco-friendliness of constructed facility using Value Engineering (VE) in the design phase. The method estimates the environmental cost relative to the amounts of energy consumption and environmental pollution occurred over the entire project life cycle. The database called "Life Cycle Inventory DB", which stores information about the amounts of environmental pollution, is used. The algorithm which retrieves the amounts of environmental pollutions from the DB and converts them into environmental costs is developed. The algorithm is implemented into a system which quantifies the eco-friendliness of constructed facility in the design phase using VE.

삶의 질이 높아지고 상품의 미적가치가 강조되면서 상품을 디자인하는데 있어 소비자의 감성을 고려하는 경향이 커지고 있다. 상품의 구매요인이 제품의 기능 중심에서 감성 중심으로 이동함에 따라 스토리텔링의 중요성이 과거보다 더욱 부각되고 있다. 이에 본 논문에서는 스토리텔링을 적용한 감성마케팅 공예디자인 개발에 목적을 두고 스토리텔링 개념의 이해와 스토리텔링을 적용한 공예디자인 사례 분석을 하고 이를 바탕으로 도자접시에 설화인 별주부전의 이야기를 과거와 현재가 융합되어 위트 있게 변형되어진 내용으로 재구성하여 스토리가 담긴 공예품을 만들고자 하였다. 공예는 상품으로의 가치나 미적 가치에 용이한 분야로 디자인의 다양성과 독창성이 추구될 수 있는 무한한 잠재력을 지니고 있다. 이제 표현적 가치뿐 아니라 의미적 가치의 부여와 함께 소비자의 감성과 욕구 충족을 시켜주는 공예디자인 개발이 필요하며 본 연구가 공예산업이 좀 더 고부가가치 산업으로 자리매김 할 수 있는 토대에 활용 되었으면 한다.

The purpose of this study is to estimate the economic value of architectural aesthetic using the contingent valuation method and to analyze the value-giving characteristics. The site survey was conducted based on the scenario of Dong-daemun Design Plaza, which is recognized as a work of outstanding architectural aesthetic. Based on 307 opinions collected, the main results are as follows: First, it could be confirmed that the higher the level of architectural aesthetic, the higher the payment amount was. The result of estimating the value of the architectural aesthetic on the basis of the fixed amount levy showed that the average payment amount was 8,859 won per person. The average payment amount was 13,014 won per person when the rejector of payment was excluded. The value of architectural aesthetic was about 13.72% of total construction cost. Second, free riding, which occurs mainly in the measurement of the value of public goods or environmental goods, appeared. This tendency is stronger in the elderly than in the younger, and in the differential amount levy than in the fixed amount levy. Third, the extreme subjectivity of architectural aesthetic value could be confirmed. While there are a lot of extreme denials of payments such as 0 won, the high-income was willing to pay a substantial amount. Fourth, it was confirmed that income factors was partly involved in the measured value.

건설 VE는 실시시기가 빠를수록 가치향상의 효과가 크므로 시공단계보다는 설계단계의 VE가 더욱 더 중요하다. 그러나 설계단계에서 발생하는 여러 가지 문제점으로 인하여 시공단계에 악영향을 미치고 있으며, 사업주체간에도 갈등을 야기하고 있다. 그러므로 설계단계에서의 품질확보가 무엇보다도 중요하다. 이에 본 연구는 설계단계의 연약지반처리공법 선정과정에서 VE/LCC 분석 사례를 통하여 비교공법별 설계기능점수(F)와 LCC비용(C)의 대비를 통해 가치지수(V)를 산정하여 최적의 공법을 선정함으로써 정성적인 판단을 정량적인 값으로 도출하는 과정을 수행하였으므로 앞으로 더욱 더 설계 VE의 확대방안이 필요함을 강조하였다.

The purpose of this study is to suggest 100MPa class ultra high strength concrete mix design model applying neural network theory, in order to minimize an effort wasted by trials and errors method until now. Mix design model was applied to each of the 70 data using binary binder, ternary binder and quaternary binder. Then being repeatedly applied to back-propagation algorithm in neural network model, optimized connection weight was gained. The completed mix design model was proved, by analyzing and comparing to value predicted from mix design model and value measured from actual compressive strength test. According to the results of this study, more accurate value could be gained through the mix design model, if error rate decreases with the test condition and environment. Also if content of water and binder, slump flow, and air content of concrete apply to mix design model, more accurate and resonable mix design could be gained.

Measurement error is one of main source of error in survey. It is generally defined as the difference between an observed value and an underlying true value. An observed value with error may be expressed as a function of the true value plus error term. In some cases, the measurement error variance may be also a function of the unknown true value. The error variance function can be rewritten as a function of true value multiplied by a scale factor. This research explore methods for estimation of the measurement error variance based on the data from complex sampling design. We consider the case in which the variance of mesurement error is a linear function of unknown true value, and the error variance scale factor is small. We applied our results to the U.S. Third National Health and Nutrition Examination Survey (the U.S. NHANES III) data for empirical analyses, which has replicate measurements for relatively small subset of initial respondents's group.

As the consuming pattern is changing with the expansion of Internet use and the development of communication technology, Internet shopping market is getting bigger and bigger. By product group, clothing and fashion related products occupy the biggest share. Accordingly, in this study it was tried to identify the effects of Internet utilization capability that enables consumers to search for the information that they need in this information flood, variety pursuit trend and product review accommodation status on shopping value, and to analyze the effects of the shopping value on the purchase behavior in online shopping malls. When factor analysis is nude on Internet use level, it was found that Factor 1 was 'Flow Experience,' Factor 2 'Internet Use Capability,' and Factor 3 'Internet Challenge Desire.' When factor analysis is made on Diversity Pursuit Propensity, it was found that Factor 1 was 'Site Diversity Pursuit Propensity,' Factor 2 'Brand Diversity Pursuit Propensity,' and Factor 3 'Brand Value Pursuit Propensity.' When factor analysis is nude on Product Review Accommodation Propensity, it was found that Factor 1 was 'Product Information Provision Propensity,' and Factor 2 'Product Information Receiving Propensity.' Except Internet Use Capability and Product Information Provision Propensity, all other factors showed high correlation. The factor influencing the entertainment value most was Internet challenge desire, while that influencing the practical value most was flow experience. When the effects of the entertainment value and the practical value on product purchase were analyzed, it was found that both of entertainment value and the practical value influenced product purchase and the practical value influenced the product purchase more than the entertainment value.

The main purpose of this research was to examine what were the factors of shopping value that consumers perceived, if there is any difference between male and female, and if male and female consumer group were divided into different groups according to the pursuing shopping value type. Data were solicited from convenience sample of 347 adults(156 male and 191 female) who were between 19 to 49 years of age. Sources for the sample were companies and apartment complexes and several colleges in Seoul and Chonan to diversify by such demographics as age and social status. The statistical methods used for this study are factor analysis and cluster analysis and Scheffe test using a SPSS 10.00 GLM. The main findings are as follows: First, four dimensions of clothing shopping values were identified as pleasure, planned, leisure, and convenience value. For male, it appeared in the order of pleasure, leisure, planned, and convenience shopping value and for female, it appeared in the order of pleasure, planned, leisure, and convenience shopping value. The most important subdimension of clothing shopping value was 'pursuing pleasure' and the least important one was 'convenience' regardless of gender. Second, three types of consumer groups for male & female were identified. For male consumers, it appeared as planned, leisure/convenience, and pleasure pursuing group. For female consumers, it appeared as pleasure, convenience, and leisure shopping pursuing group. Here, pleasure is a common factors to affect shopping itself free from gender, but male does shopping with plan and female with pleasure.

첫번째 질문-포용적 디자인을 진정으로 포용적으로 만드는 방법은 무엇인가. 대부분의 포용적 디자인 제품들이 사용자들에게 그다지 매력을 주지 못하는 이유는 디자이너들이 제품의 사용성의 개선에 치중하면서도 제품과 사용자를 연결해 주는 감성적 가치를 간과하기 때문이다. 디스플레이와 키보드를 크게 하는 등의 사용성의 개선책은 때로 제품을 매력이 없고 관심을 끌지 못하게 만들어 결과적으로 원래의 의도와는 달리 포용성을 충족시키지 못하게 되게 된다. 감성적 디자인이란 단순히 재미있는 제품을 만드는 것이 아니라, 사용하기 즐거운 제품을 만드는 것을 의미한다. 긍정적인 감성적 디자인은 제품에 대한 호감을 증가시켜서 사용자로 하여금 제품에 대한 연결감을 고양시키고, 이러한 감성적 연결감은 제품을 사용하는 것을 즐겁게 할 뿐만 아니라, 사용 방법을 배우는 것 조차 즐겁게 만든다. 또한 제품에 대한 주의를 높이고 지루함을 줄여서 사용성에 따르는 많은 문제를 해결해 준다. 더 많은 사람이 즐겁게 사용한다면 그 제품의 포용성은 더욱 높아질 것이다. 두번째 질문-포용적 디자인은 혁신적인 상품성이 있을 수 없는가. 대개의 포용적 디자인 제품은 혁신적이지 못하고, 따라서 새로운 시장 기회를 만들지 못한다. 감성적 접근방법이 사용자 측면의 가치를 높이는 일이라면, 혁신적 디자인 접근 방법은 시장에서의 가치를 높이는 일이다. 이는 더 많은 기업의 포용적 디자인 제품의 개발을 촉진시키게 된다. 본 논문에서는 포용적 디자인에서의 감성적 디자인 방법의 효과를 조명하고, 감성적 디자인 접근 방법이 포용적 디자인 제품을 혁신적으로 만들 수 있는 가능성을 다룬다. 또한 제시된 디자인 프로세스를 통하여 이러한 과정의 사례를 보여준다.
