In a situation that ordinal preferences on multiattribute weights are captured, we present two solution approaches: an exact approach and an approximate method. The former, an exact solution approach via interaction with a decision-maker, pursues the progressive reduction of a set of non-dominated alternatives by narrowing down the feasible attribute weights region. Subsequent interactive questions and responses, however, sometimes may not guarantee the best alternative or a complete rank order of a set of alternatives that the decision-maker desires to have. Approximate solution approaches, on the other hand, can be divided into three categories including surrogate weights methods, dominance value-based decision rules, and three classical decision rules. Their efficacies are evaluated in terms of choice accuracy via a simulation analysis. The simulation results indicate that a proposed hybrid approach, intended to combine an exact solution approach through interaction and a dominance value-based approach, is recommendable for aiding a decision making in a case that a final choice is seldom made at single step under attribute weights that are imprecisely specified beyond ordinal descriptions.

This study was performed to investigate the influence of seafood education on students' preferences and perceptions towards seafood menu items provided by school foodservice. The 62 representative menu items were selected from the complete menus provided by 10 high schools located in the Daegu Kyungpook area. Five hundred students were surveyed and 484 questionnaires were analyzed. The preference ($3.25{\pm}0.92$) of seafood menu items was not sufficiently high. The preference order of seafood menu items was rice > noodle > deep fry > grill> stir fry > seasoned dish > soup/stew > steam > pan fry > braise > fermented fish. Conversely, the most frequently provided menu items were soup/stew (31.34%), braise (18.06%), stir fry (15.61%), and seasoned dish (14.83%); the results showed no significant correlation between students' preference and the frequency with which the items were provided. Seafood education positively influenced the students' preference (p<0.001) and perceptions of the seafood acceptability (p<0.01), nutritional value (p<0.05), menu variety (p<0.05), diversity of cooking methods (p<0.001), cleanliness (p<0.001), and leftover amounts (p<0.01). However, more than half the students participating in this study have never received any type of education on seafood. Therefore, a practical program for seafood education should be developed to promote seafood consumption among young students.

Nowadays, the concept of outdoor campus is different from the past. U-Campus with a well-developed high-speed computer network is no longer a constraint on the campus interior and exterior spaces. From this point of view, today's large-scale university outdoor spaces need to be changed from a simple green space. The university campus outdoor spaces need to be changed into a new concept space. This study analyzed the changes in academic activities and preferences of college students who are users of university campus outdoor spaces and it is aimed at space planning that reflects the preference. The university campus should be remodified through changes in students' behaviors. Participants in this study were four different departments students (Social science, Physical education, Natural science and Engineering). The preference results of 17 items were analyzed. As a result of this preference analysis, we found that there is a difference in preference among students belonging to four different departments students. In conclusion, this study will propose that the preferences of each college should be considered in planning the outdoor rest spaces of university campus.

The purpose of this study was to investigate the need to develop foods for the elderly based on their food preferences. A one-to-one survey method was used for data collection, and the survey was conducted on 165 elderly people (male: 47, female: 118) attending senior welfare centers in Seoul. The results of this study show that the preferred cooking method was steaming rather than stir-frying. Vegetables (4.24), fruits (4.22), Kimchi (3.87), fish (3.83), tofu (3.81), rice-cakes (3.65), dairy products/eggs (3.47), meat (3.45), noodles (3.44), seafood (3.44), poultry (3.23), bread/cookies (3.10) showed high preferences in order (p<0.05). The respondent's chewing & swallowing degree were "Not uncomfortable chew" 31.5%, "Hard food, and a big food is a little difficult to intake". 37%, "Hard food, and a big food is difficult to intake" 11.5%, "Small food, and soft foods can intake" 11.5%, and "It is difficult to intake solid food" 1.2%. Foods that were difficult to chew were meat 28.3%, seafood 15.2%, vegetables 15.2%, nuts 14.1%, fruits 12.0%, Kimchi 8.7%, and other 6.5%. For respondents, the most important factors affecting choice of elderly foods were flavor (48.5%), hygiene (43.0%), and nutrition (36.4%). The elderly wanted "Ready to eat (RTE)" 53.9%, "Ready to heat (RTH)" 15.8%, "Ready to cook (RTC)" 21.2%, and 'Fresh cut product" 9.1%.

This study analyzed consumers' preferences and price sensitivity to native chickens. A survey was conducted from Jan 6 to 17, 2014, and data were collected from consumers (n=500) living in Korea. Statistical analyses evaluated the consumption patterns of native chickens, preference marketing for native chicken breeds which will be newly developed, and price sensitivity measurement (PSM). Of the subjects who preferred broilers, 24.3% do not purchase native chickens because of the dryness and tough texture, while those who preferred native chickens liked their chewy texture (38.2%). Of the total subjects, 38.2% preferred fried native chickens (38.2%) for processed food, 38.4% preferred direct sales for native chicken distribution, 51.0% preferred native chickens to be slaughtered in specialty stores, and 32.4% wanted easy access to native chickens. Additionally, the price stress range (PSR) was 50 won and the point of marginal cheapness (PMC) and point of marginal expensiveness (PME) were 6,980 won and 12,300 won, respectively. Evaluation of the segmentation market revealed that consumers who prefer broiler to native chicken breeds were more sensitive to the chicken price. To accelerate the consumption of newly developed native chicken meat, it is necessary to develop a texture that each consumer needs, to increase the accessibility of native chickens, and to have diverse menus and recipes as well as reasonable pricing for native chickens.

Restructured meat (RM) products are gaining importance as an essential component of the meat industry due to consumers' interest in health benefits. RM products imply the binding or holding of meat, meat by-products, and vegetable proteins together to form a meat product with meat's sensory and textural properties. RM products provide consumers with diversified preferences like the intake of low salt, low fat, antioxidants, and high dietary fiber in meat products. From the point of environmental sustainability, RM may aid in combining underutilized products and low-valued meat by adequately utilizing them instead of dumping them as waste material. RM processing technique might also help develop diversified and new hybrid meat products. It is crucial to have more knowledge on the quality issues, selection of binding agents, their optimum proportion, and finally, the ideal processing techniques. It is observed in this study that the most crucial feature of RM could be its healthy products with reduced fat content, which aligns with the preferences of health-conscious consumers who seek low-fat, low-salt, high-fiber options with minimal synthetic additives. This review briefly overviews RM and the factors affecting the quality and shelf life. Moreover, it discusses the recent studies on binding agents in processing RM products. Nonetheless, the recent advancements in processing and market scenarios have been summarized to better understand future research needs. The purpose of this review was to bring light to the ways of sustainable and economical food production.

This study was undertaken with 237 fifth grade children to investigate the factors, affecting the seafood prefrerence of elementary school children as one of the approaches to find strategies to promote these children's acceptance of seafoods. Subjects for this study were from one public elementary school under meal service located each in Boryeoung-city Chungcheongna Co (coastal area) and Chelowon gen Gangwon do land locked area) The preferences for than those in Boryeong and differences in may items were significant Among four area gender groups girls in Cheolwon had the lowest preference for most seafood items except cephalocoda for which the preference of body in Cheolwon was the lowest Making soup was the least preferred method to cook fish regardless of gender and area, while grilling was the most or the second most preferred in each gender area group Compared to girls bodys had a higher preference for deep frying The seafood preferences of mothers in both areas were similar to those of their children except for processed seafoods which were even more preferred by the children than mothers. Gender, distance from the sea and the method of preparation/cooking seemed to affect the children's preference more than their mother's preference and frequency of serving in the case of seafood. And the effect of gender distance from the sea and cooking methods differed for each seafood category The several suggestions to improve seafood preference especially in land locked area are discussed.
