비시장재의 가치를 추정하는 많은 연구들은 비시장재에 대한 선호가 모든 경제주체에 있어서 동질적이라고 가정한다. 그러나 현실적으로 비시장재에 대한 선호가 경제주체마다 다를 수 있기 때문에 경제주체간 선호의 이질성을 가정하는 것이 합리적이며 가치추정의 편의를 감소시키게 될 것이다. 본 연구는 방사성 오염 물질인 라돈 가스 농도의 저감에 대한 선호와 도로교통 및 원자력발전의 안전에 대한 선호가 각각 가계들 사이에 이질적일 것인지, 그리고 가계들의 선호가 동질적임을 가정하는 경우에 비해 모형 및 비시장재 가치 추정에 어떠한 영향을 미치는지 분석하였다. 속성가치선택법(choice experiments)과 중첩로짓(mixed logit) 모형을 이용한 결과, 이질적 선호를 허용하는 것이 이를 배제하는 것보다 설명력 있는 모형을 가져다 주었다. 그리고 라돈 농도 저감 및 도로교통 안전 각각에 대하여 이질적 선호가 가계들 사이에 뚜렷이 존재하는 것으로 나타났다. 그러나 원자력발전 안전에 대한 선호의 이질성은 뚜렷이 존재하지 않았다. 이질적 선호를 배제하는 경우와 비교할 때 이를 허용하는 경우의 지불의사액은 라돈 농도 저감의 경우에 평균 2.44배 증가하였으며, 도로교통 안전의 경우에는 1.74배 증가하였다.

Mealworm is the most widely used edible insect in Korean traditional food. In this study, the quality characteristics and antioxidant activity of Garaedduk containing different proportions of powdered mealworm (0%, 3%, 6%, 9%, and 12%) were evaluated in order to enhance the utilization of mealworm. The results revealed that moisture content decreased while pH and starch elution increased, with increasing amount of mealworm. Furthermore, the amount of total amino acids, essential amino acids, and non-essential amino acids increased with increasing amount of mealworm. Regarding chromaticity, the L value decreased while the a and b values increased as the amount of mealworm increased. The addition of 6% mealworm showed slight differences in the pore size and surface smoothness as compared to plain Garaedduk. Texture, hardness, chewiness, and gumminess increased, but cohesiveness decreased with increasing amount of mealworm. The preference test evaluating the appearance, flavor, taste, texture, and overall preference showed that 6% mealworm additive group had the highest preference. In addition, antioxidant activity of the newly developed Garaedduk increased with increasing amount of mealworm. In conclusion, Garaedduk enriched with 6% mealworm showed promising results for developing rice cake with improved nutrition and antioxidant activity and excellent overall preference and quality.

In light of the problem of imported apparel that tends to increase rapidly this study was intended to inquire into the assessment of male and female college students about the brands of imported apparel relative to dom-estic apparel based on quality perception price pirceptionand social psychological perception. And it is concerned with making a compara-tive study of the difference in consumer's con-sciousness of clothing between subjects by dividing them into the group of preference for imported apparel the group of non-preference for it on the basis of their ratings. As a consequence the following study results were obtained. 1) As a result of comparing college students' ratings for quality perception price perception and social psychological perception of impor-ted apparel all three factors were shown to have the high average value in care of the group of preference for imported apparel and to have a significant difference between groups. 2) As a consequence of making a compara-tive study of the difference in the clothing at-titude between groups the group of prefer-ence for imported apparel showed the high av-erage value about brand preference and identi-fication clothing involvement and interper-sonal perception through clothing and to hjave a significant difference with the group of pref-erence for imported apparel in terms of the peripheral environment and the place of pur-chase. 3) As a result of making a comparison of the difference in demographic factors between groups it was analyzed that female clollege students especially college women in the departments of art and physical education had the higher preference for imported apparel. And it was shown that they had the higher preference for imported apparel the greater amount of pocket money they had. Broader and deeper studies are required to be made about imported apparel in a multifaceted way. Therefore follow-on studies will have to be actively conducted such as a study of con-sumer's evaluation about imported apparel and domestic apparel charged at th same range of prices and a study of the difference on con-sumer's consciousness of imported apparel found over age span of consumers.
