  • 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.

  • 본 연구는 철도의 선택 및 비사용 가치를 논의한다. 교통서비스의 총경계적 가치는 여러 가지로 분류될 수 있으나, 사용 가치, 선택 가치, 비사용 가치로 구분할 수 있다. 사용 가치는 특정 교통시설의 실제 이용에 대한 지불용의액이다. 반면 선택 가치는 특정 교통시설을 주로 이용하지 않으나 잠재적 이용 가능성에 대한 지불용의액이다. 마지막으로 비사용 가치는 특정 교통시설을 실제로 또는 선택적으로 이용하지 않으나, 그 교통시설에 내재한 대리적, 이타적, 기능적, 존재적 가치에 대한 지불용의액이다. 선택 및 비사용 가치를 추정하기 위하여 이중제약 양분선택형 잠재선호조사를 시행한다. 조사된 자료를 생존모형을 이용하여 분석한다. 모형의 모수 추정치를 이용하여 철도의 선택 및 비사용 가치를 산정한다. 마지막으로 연구결과의 (예비)타당성조사 활용방안을 제시한다.

  • This study aimed at identifying the effectiveness and preference orientation of an social integration policy for rural married immigrant women according to eight life areas. For this purpose was surveyed non-multicultural residents and multicultural couples. By analysis, frist, the assimilation orientation as an model of integration policy for the women was preferred most highly at the life language area by every respondent. The multiculturalism orientation was preferred most highly at the private area such as dietary-life culture. Second, ANOVA analysis showed that the positive effectiveness on the language policy are evaluated most highly by the respondent having assimilation preference orientation. And the positive effectiveness on dietary-life culture policy are evaluated most highly by the respondent having multiculturalism orientation. Third, positive effectiveness level of the policy estimated by the resident was lower than it of multicultural couple significantly. In conclusion, based on results of this study, it can be seen as on that point preference orientation of integration policy for the women, the domain specificity is present in the attitude of the multicultural couple and resident. Therefore it suspect that integration policy for the women should be considered differently according to life sphere.

  • In order to build strong brand equity in the current market circumstances, it is essential to understand the core dimensions of brand image, which is brand personality. The objectives of this study were to identify the brand personality dimensions of a casual brand, "BeanPole," and to investigate the effects of the brand personality on BeanPole buyers' brand preference, satisfaction and loyalty. The data were collected via a web survey. The sample consists of 500 people between the ages of 18-45 who are familiar with Bean Pole casual clothing brand (male- 40%; female-60%). Sixty-six percent of the sample indicated that they had purchased the Bean Pole clothing during the last three years. A total of five factors were extracted from the brand personality index scale: They were excitement/sophistication, competence, sincerity, ruggedness, and smoothness. Compared to the B/P non-buyers, B/P buyers tended to rate excitement/sophistication, competence, sincerity, and the smoothness brand personality dimensions higher. Multiple regression analysis revealed that excitement/sophistication, competence, sincerity and ruggedness brand personality were significant predictors of respondents' casual clothing brand preference, satisfaction, and brand loyalty. Among these significant predictors, competence was the best predictor of casual clothing brand preference, satisfaction and brand loyalty. Based on these findings, strategic implications are discussed.

  • 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.

  • 본 연구는 다목적 유전자알고리즘을 이용하여 Tank 모형의 매개변수를 추정하는데 있어서 선호적순서화(preference ordering)를 적용한 연구로써, 목적함수의 개수가 여러 개인 경우에 발생할 수 있는 파레토최적화의 단점을 해결하기 위한 것이다. 최적화를 위한 목적함수는 모두 4가지를 사용하였으며, 선호적순서화를 통해서 구한 2차 효율성(2nd order efficiency)을 가지면서 정도(degree)가 3인 4개의 해 중에서 1개의 해만을 최우선해로 선정하였다. NSGA-II로 도출된 최우선해의 적합성을 살펴보기 위해서, 자동보정방법인 Powell 방법과 SGA(simple genetic algorithm)를 매개변수 자동보정 방법으로 이용하고 하나의 단일목적함수로 사용해서 최적화한 결과와 비교해보았으며, 비교결과 다목적 유전자 알고리즘을 4개의 목적함수에 모두 적용해서 한번에 도출된 매개변수를 이용한 결과가 보정기간뿐만 아니라 검정기간에 대해서도 비교적 양호한 결과를 나타내는 것으로 나타났다.

  • 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.
