購買意思決定過程에서의 滿足과 不滿足에 관한 硏究 : 消費者市場의 경우를 中心으로 Analysis of the Consumer Market
兪大根 又石大學校 1982 論文集 Vol.4 No.-
While serious questions are being raised about consumer welfare despite the wide acceptance by business of the consumer-oriental marketing philosophy, relatively little is known about consumers's satisfaction and dissatisfaction. The study reported here is undertaken to help fill that void by finding out how satisfied or dissatisfied consumers are with their experiences in arriving at purchase decisions instead of phenomenological consumer satisfaction or dissatisfaction related to the usage or consumpton of products and services. To find out directly from consumers how they felt in a specific buying experience, we have studied the subject by theoretical and empirical research. Chapter 2 suggests the main aspects and reasons why the prepurchase experience might give rise to dissatisfaction. The aspects include the adequacy of available product alternatives for meeting consumer wants; access to desired prepurchase information; the experience of visiting retail stores; the pace of the shopping experience: the tesk of evaluating and choosing among alternatives; and anxiety about making a satisfactory choice. The findings of empirical survey in chapter 3 indicate appreciable satisfaction and fail to support the view of widespread discontent with the purchase decision process among consumers. While the findings here constitute only limited evidence owing to potential limitation related to the adequacy of the sampling design in respondents and choice of products, they point to the tentative conclusion that maketers may be succeeding reasonably well in providing acceptable levels of satisfaction to the buying public. Our results suggest a need for research to learn more about the characteristics of consumers who are expressing feeling of satisfaction and dissatisfaction.
식품소매시스템의 발전에 대한 이론적 고찰 : 개발도상국의 응용적 적용을 중심으로 Implications for Developing Countries
兪大根 又石大學校 1986 論文集 Vol.8 No.-
The retailing systems that have evolved in developed and developing economics of the world clearly share certian common chareateristics, but they also differ from each other in many ways. The study reviews histories, nature, development and problems of food retailing instilutions to find out an important basis for any theoretical or applied undertaking in the area of food retailing system development, especially in the developing countries. The article explains and contrasts the evolution process and trends in food retailing system and presents a comprehensive framework, depicting the relationships between various environmental factors and the characteristics of food retailing systems in both economics. Finally we provide effective applications for public policies in mondernizing food retailing system in developing nations and implications for future research in this field.

본 논문에서는 한글의 구조적 특징이 반영된 획들의 통계적인 분포에 근거한 필기 문자열의 기울기 보정 방법을 제안한다. 기존의 기울기 보정 방법들은 대부분 영문위주의 보정 방법으로, 영문과 달리 2차원적 구조를 갖는 한글에 적용하는데는 많은 문제가 있다. 일반적인 보정 방법을 적용할 경우 한글에 내재하는 강한 대각선획의 영향으로 인한 역보정의 문제가 가장 많이 나타나며. 기울어진 문자열을 제대로 보정하지 못하는 경우도 빈번하다. 제안하는 방법에서는 추출된 획들의 기울기 분포를 K-평균 군집법을 적용하여 수직획과 대각선획의 두 개의 군집으로 분류하고, 가우시안 분포로의 모델링을 통해 대각선획을 제외하고 수직획만을 이용하여 기울기 보정을 수행하였다. 임의의 필기자에 의해 필기된 우편봉투 주소 문자열 1,300개에 대해 제안하는 방법과 기존의 방법들을 적용하여 실험한 결과 제안하는 방법이 기존방법들에 비해 역보정률을 크게 낮추고, 기울어진 문자열에 대해 완벽한 보정 성능을 보여 그 우수성이 입증되었다. A slant correction method for handwritten Korean strings based on analysis of stroke distribution, which effectively reflects structural properties of Korean characters, is presented in this paper. The method aims to deal with typical problems which have been frequently observed in slant correction of handwritten Korean strings with conventional approaches developed for English/European languages. Extracted strokes from a line of text image are classified into two clusters by applying the K-means clustering. Gaussian modeling is applied to each of the clusters and the slant angle is estimated from the model which represents the vertical strokes. Experimental results support the effectiveness of the proposed method. For the performance comparison 1,300 handwritten address string images were used, and the results show that the proposed method has more superior performance than other conventional approaches.
