입주전 신축공동주택의 HCHO, VOCs 및 TVOC 오염농도 실태조사에 관한 연구
김건우(Keon Woo Kim),박진철(Jin Chul Park) 한국실내환경학회 2008 한국실내환경학회지 Vol.5 No.2
This study aims to present the fundamental strategies for improving the Indoor Air Quality (IAQ) in newly unoccupied apartment units. The results of this study can be summarized as follows; The field survey of 160 newly unoccupied units with airtight doors and windows showed that the concentrations of HCHO and TVOC were higher than the standards. The emission rates of HCHO and TVOC were proportional to the height. The small chamber test of pollutant concentration for building materials showed that pollutants were emitted dominantly from the wood furnishings and adhesives.

Recently the problem of indoor air quality in new apartment houses has been seriously raised, and is growing to the social problem such as sick building syndrome(SBS) or sick house syndrome(SHS), by threate the health of citizens. The results of this study are as follows; the field survey of 120 newly apartment houses, they had airtight doors and windows, so the concentration of HCHO and TVOC were higher the standards. and the emitted rates of HCHO and TVOC were proportioned to height.
소비자 가치기반 디자인 평가 모형 개발 : 제품 속성, 인지 속성, 소비자 가치의 3단계 접근

최근 IT 기술의 발전 속도가 매우 빠르며, 소비자의 욕구도 다양하게 변화하고 있다. 특히, 스마트폰, 태블릿을 비롯한 여러 기기들이 빠른 속도로 출시되고 있으며, 스마트폰은 교체 수명주기가 줄어들면서 하나의 패션 아이템으로 자리 잡았다. 이들은 기능상의 발전도 있지만, 디자인 등과 같은 외형상의 발전에 초점을 맞추어 제품들이 출시되고 있다. 디자인이 중요해짐에 따라 소비자들이 어떤 메커니즘으로 디자인을 평가하는지에 대한 모형이 필요해졌다. 기존 연구들은 소비자들의 인지와 가치 부분에 초점을 맞추어 정성적인 부분을 정량화하려는 시도가 있었다. 그러나 본 연구는 인지와 가치의 기반이 되는 부분은 정량적인 제품 속성에 있다고 판단하였다. 제품 속성과 소비자가 느끼는 인지 수준, 최종적으로 전달된 가치들이 모두 반영된 3단계 디자인 평가 모형을 통해 제품 속성이 소비자 인지와 가치에 미치는 영향과 그 이유를 분석하고자 한다. 본 연구의 이론적 공헌은 기존 연구와 다르게 인지와 가치만이 아닌 제품 속성까치 포함한 전체적인 연구를 진행하였다는 점과, 소비자가 왜 그렇게 느끼는 지에 대한 설명, 그리고 스마트폰만이 아닌 다른 HCI와 UX 분야에서도 적용 가능한 모델을 제시했다는 점에서 의의가 있다. 또한, 실무적 공헌으로는 제품 개발 시 디자이너의 관점과 소비자의 가치 관점의 차이를 설명할 수 있고, 실제 소비자들이 어떤 속성에 주목하여 어떤 가치를 느끼는지에 대한 가이드를 제공했다는 점, 빅데이터와 인공지능 학습과 결합하여 진화 가능한 디자인 평가모델을 제안하였다는 의의가 있다.

Recently, consumer needs are diversifying as information technologies are evolving rapidly. A lot of IT devices such as smart phones and tablet PCs are launching following the trend of information technology. While IT devices focused on the technical advance and improvement a few years ago, the situation is changed now. There is no difference in functional aspects, so companies are trying to differentiate IT devices in terms of appearance design. Consumers also consider design as being a more important factor in the decision-making of smart phones. Smart phones have become a fashion items, revealing consumers’ own characteristics and personality. As the design and appearance of the smartphone become important things, it is necessary to examine consumer values from the design and appearance of IT devices. Furthermore, it is crucial to clarify the mechanisms of consumers’ design evaluation and develop the design evaluation model based on the mechanism. Since the influence of design gets continuously strong, various and many studies related to design were carried out. These studies can classify three main streams. The first stream focuses on the role of design from the perspective of marketing and communication. The second one is the studies to find out an effective and appealing design from the perspective of industrial design. The last one is to examine the consumer values created by a product design, which means consumers’ perception or feeling when they look and feel it. These numerous studies somewhat have dealt with consumer values, but they do not include product attributes, or do not cover the whole process and mechanism from product attributes to consumer values. In this study, we try to develop the holistic design evaluation model based on consumer values based on three-step approach from product attributes, perceived attributes, to consumer values. Product attributes means the real and physical characteristics each smart phone has. They consist of bezel, length, width, thickness, weight and curvature. Perceived attributes are derived from consumers’ perception on product attributes. We consider perceived size of device, perceived size of display, perceived thickness, perceived weight, perceived bezel (top - bottom / left - right side), perceived curvature of edge, perceived curvature of back side, gap of each part, perceived gloss and perceived screen ratio. They are factorized into six clusters named as ‘Size,’ ‘Slimness,’ ‘No-Frame,’ ‘Roundness,’ ‘Screen Ratio,’ and ‘Looseness.’ We conducted qualitative research to find out consumer values, which are categorized into two: look and feel values. We identified the values named as ‘Silhouette,’ ‘Neatness,’ ‘Attractiveness,’ ‘Polishing,’ ‘Innovativeness,’ ‘Professionalism,’ ‘Intellectualness,’ ‘Individuality,’ and ‘Distinctiveness’ in terms of look values. Also, we identifies ‘Stability,’ ‘Comfortableness,’ ‘Grip,’ ‘Solidity,’ ‘Non-fragility,’ and ‘Smoothness’ in terms of feel values. They are factorized into five key values: ‘Sleek Value,’ ‘Professional Value,’ ‘Unique Value,’ ‘Comfortable Value,’ and ‘Solid Value.’ Finally, we developed the holistic design evaluation model by analyzing each relationship from product attributes, perceived attributes, to consumer values. This study has several theoretical and practical contributions. First, we found consumer values in terms of design evaluation and implicit chain relationship from the objective and physical characteristics to the subjective and mental evaluation. That is, the model explains the mechanism of design evaluation in consumer minds. Second, we suggest a general design evaluation process from product attributes, perceived attributes to consumer values. It is an adaptable methodology not only smart phone but also other IT products. Practically, this model can support the decision-making when companies initiative new product development. It can help product designers focus on their capacities with l
