自動車 3社의 消費者行動에 관한 硏究 : 스텐톤 모델을 중심으로 A Structural Approach to the Stanton Model
金弘大 新羅大學校 1990 論文集 Vol.30 No.-
This paper aims to explain consumer behavior for the three company:HYUNDAI, DAEWOO and KIA. This paper has dicussed consumer behavior based on a structural approach to the Stanton model. It has summarized theoretical support for the model and has evaluated its application in a marketing decision environemnt. The results of this research suggest that this model is conceptually sound and managerially useful. Application of the model provides detailed data for determining market position and designing strategy to modify that position. We would want to understand cultural, social, personal, and psychological factors that operate in her life. Cultural factors include the culture from whcih she comes, her subculture identifications and her social class. Social factors include the influence of other people in her life, particularly her reference groups, family, and roles and statuses. Personal characteristics life style, and personality. Finally, psychological characteristics include her motivation, perceptions, attitudes and beliefs, and learning. The company's task is to work hard to get its brand included in the buyer's awareness set and to remain in the successive lonsideration and choice set. The marketer must research the other brands that are likely to be include and the criteria used by the buyer as she moves to successively smaller sets in making her decision. We believe that a variety of theoretical and analytic models in the marketing literature can and do help managers make better decisions. The informed manager selects those models and measurements that are right for the specific circumstances of the managerial problem being examined.

For the expanding of urban green space in Daegu, Korea, the flat-rooftop which is a character of the modern Korean buildings was considered. Existing cases and guidelines and technical methods of rooftop construction were reviewed to understand the underlined difficulties in practice, and a questionnaire survey was carried out to highlight the attitude of the general public toward rooftops. Majority of the rooftop is still in use of the traditional way such as a storage, laundry. In many cases, however, there is a simple pattern of installation of plants, for example, planting flowers, fruit trees and vegetables. Nevertheless the existence of any green elements on the rooftop, the general public expressed positive attitudes in the greening of their rooftops. Moreover, key issues identified as negative factors are the lack of administrative support system and information, financial difficulties, and the concern of negative influence for building structure. A model of strategy is suggested based on four steps to stimulate and to encourage the greening of the rooftop in Daegu, and four detailed suggestions are produced under the model.

질소산화물 ($NO_X$)은 고정원(화력발전소, 산업시설) 및 이동원(자동차, 선박) 등에서 배출되어지며, 발암물질 및 광화학 스모그의 주범으로 작용하고 있다. 선택적 촉매 환원법(SCR)은 $NO_X$를 제거하는 가장 효율적인 방법이며, 상업용으로 사용되어지는 $V_2O_5-WO_3/TiO_2$계 촉매에서 $V_2O_5$ 함량은 0.5~3 wt%, $WO_3$ 함량은 5~10 wt%이다. 촉매 성분 중 $V_2O_5$의 경우 $NO_X$ 환원 반응을 통해 촉매 작용을 촉진시키지만, 과량으로 첨가될 경우, $SO_2$에서 $SO_3$로의 산화 반응을 증가시킨다. 본 연구에서는 높은 탈질 효율을 유지시킴과 더불어, 바나듐의 함량을 줄이기 위하여, 그래핀을 바나듐 담지 matrix로 사용하여 나노복합체를 합성하였으며, 합성된 나노복합체를 첨가하여 Honeycomb형 1 inch SCR 촉매를 제조하였다. 제조된 SCR 촉매는 XRD(X-ray Diffraction), XRF(X-ray Fluorescence Spectrometer), BET(Brunauer, Emmett & Teller) 등의 분석을 통해 물성 평가를 진행하였으며, Micro Reactor(MR)를 이용하여 활성평가를 진행하였다. 그 결과, 촉매 상용 운전 온도인 $350^{\circ}C$에서 나노복합체가 첨가된 SCR 촉매의 탈질 효율은 77.1 %로 상용촉매의 탈질 효율인 77.8 %와 유사한 효율을 나타내는 것을 확인하였다. Nitrogen oxides ($NO_X$) was emitted from flue gas of stationary sources and exhaust gas of mobile sources, can leads to various environments problems. Selective Catalysts Reduction (SCR) is the most effective $NO_X$ removal system. Commercial $V_2O_5-WO_3/TiO_2$ catalysts, usually containing $V_2O_5$ 0.5~3 wt%, $WO_3$ 5~10 wt%, and $V_2O_5$ is active in the reduction of $NO_X$ but also in the desired oxidation of $SO_2$ to $SO_3$. To reduce the amount of vanadium, using graphene matrix supported vanadium to synthesize nanocomposite. Then, we fabricated to 1 inch honeycomb type of SCR catalysts adding graphene-vanadium nanocomposite. The chemical-physical characteristics and the catalytic activity were performed by XRD, XRF, BET and Micro-Reactor (MR). As a result, the De-NOX performance was showed, similar to the commercial catalyst activity as 77.8 % and using nanocomposite catalyst as 77.1 % at $350^{\circ}C$.
