The objective of this study was to reduce the waste rate of onion peel, which has excellent functionalities, and to promote its industrial utilization. The methodology involved preparing beef jerkies using liquid seasonings with 0% (OPE0), 50% (OPE50) and 100% (OPE100) onion peel extract (OPE) of domestically produced onion, respectively; and assessing their antioxidant activities and quality characteristics. As the amount of added OPE increased, the contents of crude protein and crude ash increased, while those of crude fat decreased. As for color values, increase in the amount of added OPE led to increase in L value and b value, but decrease in a value. The measurement of mechanical texture showed that hardness and cohesiveness decreased as the amount of added OPE increased. TBARS (thiobarbituric acid reactive substance) content decreased as the amount of added OPE increased. And the amount of added OPE increased, all the antioxidant activity of beef jerky increased. Acceptability test showed the highest preference for OPE50 with regard to flavor, taste texture and overall acceptability. Quantitative descriptive analysis (QDA) showed that increase in the amount of added OPE led to increase in meat color, salty taste, sweet taste, meat flavor and chewiness and decrease in off-flavor. According to principal component analysis (PCA), OPE50 and OPE100 had high levels of the sensory attributes that increase preference-such as meat color, salty taste, sweet taste, meat flavor and chewiness. Based on such results, it was established that 50% is the optimal mixing ratio of OPE for preparing a beef jerky of high preference that also has excellent quality characteristics and antioxidant activity.

The purpose of this study was to develop a technology commercialization strategy by analyzing the consumer preference for low-sodium instant noodle ramen, which has a sodium content of 1,730 mg or less. For the commercialization of such low-sodium ramen, this study examined how much consumers would pay through an analysis of consumer preference by conjoint analysis. This study surveyed 1,004 men and women in their 20 s and 50 s between the ages of 20 and 50 years in Korea using an online survey. If the price of conventional instant noodle ramen is KRW 4,000 (approximately USD 3.57) per 5 packs for one pack of 5 servings in a supermarket, this study surveyed how much more they respondents would pay if the sodium was reduced by 10.0, 20.0, and 30.0%. The study found that if sodium was reduced by 10.0, 20.0, and 30.0%, the respondents would pay as much as KRW 4,180, KRW 4,307, and KRW 4,515, respectively. The attributes of low-sodium instant noodle ramen were examined according to the degree of sodium reduction, vegetable protein ingredients, brand, where to buy and price with each level. The Marginal Willingness To Pay (MWTP) was analyzed as follows. If the sodium content of ramen soup is reduced by 1.0%, the amount that can be paid would be KRW 105.78. Respondents could pay KRW 1,673 more for famous brand ramen than an unknown brand ramen. The study results indicated that when a new product is developed and released, it can be expected to increase sales of the new product by understanding the foreseeable value that consumers could pay for and realize the technological commercialization of the technology.

본 연구의 목적은 소비자의 쇼핑 시 소비자의 상품(식품) 선택 특성이 온, 오프라인의 업태별 선호도와 옴니채널 선호도에 영향을 미치는가를 분석하여 유통업체의 마케팅 전략 수립에 시사점을 얻기 위함이다. 연구모형은 소비자의 식품 선택 특성이 각각 업태별 선호도와 옴니채널 선호도에 미치는 영향으로 구성 되었다. 총 477부의 설문조사를 토대로 분석한 결과를 요약하면 다음과 같다. 첫째, (1) 식품의 선도, (2) 맛, (3) 품질, 안전, (4) 시식시음, (5) 식품의 기능 및 정보, (6) 원산지, (7) 브랜드 충성도의 7가지 특성을 활용한 식품 구매 특성은 업태별로 다양하게 영향을 미치는 것으로 나타났다. 채택된 가설은 브랜드 충성도(5회), 선도(3회), 시식 시음(3회), 원산지(1회) 순으로 선정이 된 것으로 보아 식품의 선택요인은 (1) 어떤 브랜드 인가, (2) 얼마나 선도가 좋은가, (3) 시식 시음으로 먹어보고 구입 한다, (4) 원산지는 확인 한다 로 압축이 되며 실제 소비자가 식품 쇼핑 시에도 7가지를 모두 활용 한다기보다는 업태별 특성에 맞는 핵심적인 선택 요인만 활용하는 것으로 보여진다. 편의점은 3개 요인이 영향을 미치고 나머지 업태는 1~2요인만 영향을 미치는 것으로 분석되었다. 둘째, 옴니채널 선호도 분석에 있어서 식품의 선택 특성이 제한적으로 영향을 미치는 것으로 나왔으며 이는 옴니채널의 개념을 소비자가 아직 명확하게 이해하지 못하는 것에 기인한다고 보여진다. 셋째, 본 연구의 분석결과는 업태 별로 다양한 영향을 미치는 식품의 선택 특성을 업태별 마케팅 전략에 반영을 할 필요성이 있다는 점과 옴니채널 이용 소비자는 식품의 품질 및 안전을 중시하고 시식을 통해 상품을 확인하고, 어느 곳에서도 신뢰를 할 수 있는 브랜드를 추구하여 온 오프라인을 동시에 이용하는 합리적인 소비를 하기 때문에 옴니채널은 합리성을 추구하는 고객이 선호도가 높을 것이라는 시사점을 제공한다. 향후 유통업의 옴니체널 전략은 많은 어려움이 예상되며, 본 연구는 유통의 패러다임을 바꾸게 되는 옴니채널을 식품의 선택특성을 활용하여 처음으로 연구를 시도한 것에 의의가 있다.

As tourist are becoming increasingly environmentally conscious, government and related companies need to establish policies or strategies that encourage ecotourism. The aim of this study is to analyze individual preferences and estimate shadow prices, namely, willingness to pay for coastal wetland ecotourism. This study applies a contingent choice method to measuring marginal WTP for each attribute (tour duration, number of visitors, guide, program) of coastal wetland ecotourism. The finding herein contribute to complementing the valuation methods by estimating various attributes of coastal wetland ecotourism and providing policy-makers with useful methodological framework and quantitative information in the decision-making process related to ecotourism.

The objective of this research is to quantitatively valuate the economic value of analysis model related to climate change mitigation and adaptation. Due to the fact that the subject of this research, which is the Korean climate change mitigation and adaptation model, has not been actualized, a conjoint analysis applying stated preference data has utilized. As results, among the many attributes considered in this research, the value of the attribute related to reflecting Korea's current situation is analyzed to be largest in both greenhouse gas (GHG) mitigation model and climate change adaptation model. Additionally, if all the considered functional aspects are assumed to be feasible, the economic value of the Korean GHG mitigation model is assumed to be 60.3 billion Korean won(KRW) and the Korean climate change adaptation model is assumed to be 51 billion KRW.

A digital cable broadcasting service is a multimedia broadcasting service that provides high definition and various supplementary services by using digital transmission. Korea implemented a complete digital broadcasting service by 2012. This study applied a choice experiment to investigate consumer preferences, and it calculated the marginal willingness to pay for this service. Moreover, we employed a multinomial probit model to relax the assumption that all respondents have the same preference for attributes being valued. The results suggest that respondents value channels, definition, video-on-demand (VOD) service, pay-per-view (PPV) service, and commerce based on TV (T-commerce). On the other hand, online gaming may be less important as an attribute for digital cable broadcasting service in Korea.

With the change of construction environment, the main body of construction industry was moved from project suppliers to consumers. Accordingly in order to strengthen competitiveness, project suppliers have to concentrate on marketing for diversification. Thus, it is required to utilize real estate marketing from the beginning of development project to introduce 'consumer-centered marketing strategies' instead of 'supplier-centered marketing'. This study aims to find out what consumers consider the most important factors when selecting apartment. According to the study, when residents select their apartment in residential area, they valued those attributes with investment, location, dwelling attribute, apartment complex attribute, unit price per square meter, in order. This result will contribute to qualitative improvement of housing development project.

The purpose of this study is to identify the elderly housing farcility design preference by comparing two groups, the present residents living in elderly housing facility and the middle aged. The latter has more housing experiences and more design oriented standard of selecting house for quality of living, while the aged are oriented more in economy and investment. It is identified that both group preferred living in elderly housing facility best to any other elderly housing type, including "aging in place." The aged are not yet very concerned about physically homelike design features, but when the middle aged need the elderly housing, it is recommended that more variety and amenity in its type, location, plan and design features. The idealistic facility planning and management system were suggested.
