The contingent valuation method used survey questions to elicit people's preferences for public goods by finding out what they would be willing to pay for specified improvement in them. The method is thus aimed at eliciting their willingness to pay in money amounts. It circumvents the absence of markets for public goods by presenting consumers with hypothetical markets in which they have the opportunities to buy the good in question. The hypothetical markets may be modeled after either a private goods market or a political market. Respondents are presented with material, often in the course of a personal interview conducted face to face. An on-site survey was conducted to 1107 randomly selected P-mountain users using a dichotomous choice questionnaire for the contingent valuation method. Seventeen different bid sets were chosen ranging from the lowest bid of 300won to the highest bid of 2,100won to elicit a reasonable entrance fee in the suggested bid had been determined, and the expected value of willingness to pay was estimated using binary-logit model. The average public value of P-mountain per individual user was estimated to be 1,055.92won∼1,995.61won according to the binary-logit model. The economic value of this P-mountain which includes both use value and existence value can be determined by aggregating the average value giving total willingness to pay for the entire population, in this case 5.491 billion ∼ 10.377 billion.

The purpose of this study is to investigate the self-image of men and the characteristics of their fashion styles, as they are fast becoming an influential consumer group. Men in the thirties and forties who had a higher-than-average interest in fashion were surveyed online and the results from this study are as follows. In terms of variations of self-image connected to situations, we found that there were strong relationships between the preference of the "charming & romantic" image to private meet-ups with acquaintances, "intelligent & classy" to official events, "rational & realistic" to everyday work in an official setting, and "modest & ordinary" to complex situations including family occasions and customary events. Those who aimed for "urban refinement - sensitive" appeal also preferred a "charming & romantic" self-image, while pursuing a "classic & modern" fashion style for official settings and a "gentle & charming" style in private settings. Those who aimed for "stable elegance - intelligent" youth" image preferred the "intelligent & classy" image, while pursuing a "stable & intelligent" fashion style in official settings, and an "intelligent yet active & young" style in private settings. Those who aimed for "rational practicality - comfortable activity" image preferred a "rational & realistic" self-image, while pursuing a "rational & practical" fashion style in official settings, and a "comfortable & active" style in private settings. Those who aimed for "ordinary modesty - plain simplicity"preferred a modest and ordinary self-image, while pursuing an ordinary fashion style, and a simple style in private settings. The various situational assessments used in this study to analyze the fashion-related circumstances for male consumers can be utilized in upcoming studies, and can be an effective indicator of situational consumer preferences in terms of men's fashion marketing and product planning strategies.

`Early adopters,` a term first used by Everett Rogers in 1957, refers to people who are among the first to try a new product and like to evaluate the product for others. Early adopters in the digital age of the 21st century, greatly influence others by exchanging information on products and writing product reviews on Internet boards. Technological products have recently been released in the fashion world to become important fashion items, and early adopters are active buyers of these products. The purpose of this study is to examine the values and characteristics of early adopters as consumers of technological fashion products, and present a standard for designing fashion products in the future. This study was based on documentary research, Internet research and in-depth interviews. Documentary research was carried out to examine the lifestyles, characteristics and consumption habits of early adopters. Internet research was done to understand the tendencies of Korean early adopters, and a total of 18 websites were studied in 7 product categories. The subjects of in-depth interviews were 6 people who were either webmasters or members of early adopter-related websites. IT field early adopters tended to pursue new technologies, and fashion early adopters placed importance on how well a person could express their own style. New, unique, useful and pretty were the key words to describe the tendencies of early adopters, and fashion early adopters preferred the latest contemporary styles. Interviewees placed most importance on price, design and function of products. Since IT related products are continuously being added on to clothes and becoming fashion products themselves, further research on technology-related fashion design would be significant.

The core parties operating application stores can be categorized into two major groups. One of which is an application store that offers manufacturing and platforms while the other being telecommunication company orientated. Each group has an affiliated partnership. In a larger group, there are three major types of partnership such as "partnership that causes an increase in traffic","partnership through the sales within the application contents" and "partnership through advertisements". In order to find out whether teenagers and potential consumers in their twenties would prefer a "message-type advertising" or an "application-type advertising". Through experiment, we also figured out which type of advertising worked more effectively between the two given types.

In Bangladesh, since the beginning of 21st century, the poultry industry has become an unparalleled platform for a quick profit, the generation of local employment, and the production of cheaper animal proteins. This paper summarizes poultry industry-related facts and figures for Bangladesh, starting from the very beginnings of this sector when poultry farming was part of subsistence family farming only to today's highly commercialized horizon, through personal experiences, secondary data analysis, spot visits, and the sharing of views and ideas with stakeholders. A critical analysis reveals that the poultry industry in Bangladesh may become multi-dimensional and more stable in the near future as it establishes sufficient backward and forward linkages to input and output supplies. We can foresee its passing the very fast growing juvenile stages of higher net profit earning and less responsible then becoming fully mature. The projected demand and production potentials of this sector are increasing, but at a slower pace than before, in the face of some important challenges like emerging disease, higher prices of inputs, consumer preferences, and strong market competition. However, evidence suggests that the production systems of poultry in Bangladesh are entering a new era to cater to the needs of consumers, society, and government as it produces healthier and more diversified, further-processed foods, in the coming years. A better economy in the country, a more health-conscious population, and the availability of new and affordable innovations in this sector might be the driving forces to support the foreseen transformations.

Flavour comprises mainly of taste and aroma and is involved in consumers' meat-buying behavior and preferences. Chicken meat flavour is supposed to be affected by a number of ante- and post-mortem factors, including breed, diet, post-mortem ageing, method of cooking, etc. Additionally, chicken meat is more susceptible to quality deterioration mainly due to lipid oxidation with resulting off-flavours. Therefore, the intent of this paper is to highlight the mechanisms and chemical compounds responsible for chicken meat flavour and off-flavour development to help producers in producing the most flavourful and consistent product possible. Chicken meat flavour is thermally derived and the Maillard reaction, thermal degradation of lipids, and interaction between these 2 reactions are mainly responsible for the generation of flavour and aroma compounds. The reaction of cysteine and sugar can lead to characteristic meat flavour specially for chicken and pork. Volatile compounds including 2-methyl-3-furanthiol, 2-furfurylthiol, methionol, 2,4,5-trimethyl-thiazole, nonanol, 2-trans-nonenal, and other compounds have been identified as important for the flavour of chicken. However 2-methyl-3-furanthiol is considered as the most vital chemical compound for chicken flavour development. In addition, a large number of heterocyclic compounds are formed when higher temperature and low moisture conditions are used during certain cooking methods of chicken meat such as roasting, grilling, frying or pressure cooking compared to boiled chicken meat. Major volatile compounds responsible for fried chicken are 3,5-dimethyl-1,2,4-trithiolanes, 2,4,6-trimethylperhydro-1,3,5-dithiazines, 3,5-diisobutyl-1,2,4-trithiolane, 3-methyl-5-butyl-1,2,4-trithiolane, 3-methyl-5-pentyl-1,2,4-trithiolane, 2,4-decadienal and trans-4,5-epoxy-trans-2-decenal. Alkylpyrazines were reported in the flavours of fried chicken and roasted chicken but not in chicken broth. The main reason for flavour deterioration and formation of undesirable "warmed over flavour" in chicken meat products are supposed to be the lack of ${\alpha}$-tocopherol in chicken meat.

Purpose - High quality films are affected by both the production stage and various variables such as the size of the movie investment and marketing that changes consumers' perceptions. Consumer preferences should be recognized first to ensure that the movie is successful. If a film is produced without pre-investigation and analysis of consumer demand and taste, the probability of success will be low. This study investigates the balance of production costs, marketing costs, and profits using game theory, suggesting an optimization strategy using the simplex method of linear programming. Research design, data, and methodology - Before the release of the movie, initial demand is assumed to be driven largely by marketing costs. In the next phase, demand is assumed to be driven purely by a movie's production cost and quality, which might also further determine consumer demand. Thus, it is essential to determine how to distribute pure production costs and other costs (marketing) in a limited movie production budget. Moreover, it should be taken into account how to optimally distribute under the assumption that the audience and production company's input resources are limited. This research simplifies the assumptions for large-scale and relatively small-scale movie investments and examines how movie distribution participant profits differ when each cost is invested differently. Results - When first movers or market leaders have to choose both quality and marketing, it has been proven that pursuing a strategy choosing only one is more likely than choosing both. In this situation, market leaders should maximize marketing costs under the premise that market leaders will not lag their quality behind the quality of second movers. Additionally, focusing on movie marketing that produces a quick effect while ceding creative activity to increase movie quality is a natural outcome in the movie distribution environment since a cooperative strategy between market competitors is not feasible. Conclusions - Government film development policy should ignore quality competition between movie production companies and focus on preventing marketing competition. If movie production companies focus on movie production quality improvement then a creative competition would ensue.

Other-regarding preferences (such as trust, reciprocity and altruism) between companies, between consumers and retailers, and between employers and employees are integral elements in determining economic performance. Social trust which is a core element of social capital, especially, is known to reduce transaction costs, help solve collective action problems, and contribute to economic, social, and political development. Therefore, social trust has been given a great deal of attention across an array of academic disciplines for its role in promoting cooperation among individuals and groups, and for its positive influence on economic performance. Most studies describe Korea as a low-trust society than Japan or China. To identify the causes of social trust, this paper focuses on differences of social values (perception on competition and wealth accumulation) in 4 countries (Japan, China, Korea, and United States). Based on World Values Survey data, this paper analyzes effects of the social values on social trust. Social trust was measured by degree to which a respondent thinks that most people can be trusted. Perception on competition was measured by the degree to which a respondent thinks that competition is harmful, and perception on wealth accumulation was done by the degree to which a respondent thinks that wealth can grow so there is enough for everyone. The results showed that social trust was affected by perception on competition and wealth accumulation. A respondent showed higher level of social trust when he (or she) perceived positively competition and wealth accumulation. For enhancing social trust in a country, it is not easy to reduce income inequality and corruption which were reported as causes of social trust by previous studies. Compared to them, social values can be changed more easily by various concrete measures like education and mass-media. Differently from previous studies this paper stresses the concrete measures to enhance social trust in a country.

This study was intended to present basic materials for the direction of product planning and marketing strategy to increase the market share of men's underwear. For this purpose, it attempted to classify the groups according to the benefit of pursuing men's underwear and analyze the differences in purchase behavior among the segmented groups. The specific purposes of the study were to investigate the purchase behavior of men's underwear, to segment the consumers into groups according to underwear benefits sought, to investigate the differences in purchase behavior among the groups, and to investigate the differences in demographics among the groups. The questionnaire was distributed to men aged the 20s to the 40s living in Seoul. A total of 297 questionnaires were used for the final analysis. As a result, the following findings were obtained. It was found that 84.8% of the respondents showed there was no favorite underwear brand. They showed the favorite color of translucent color, the favorite style of trunk and brief, the favorite post-processing of silver nano, deo processing, and the favorite material of charcoal. In purchasing men's underwear, the respondents showed a preference for simple image, and the discount store as the place of purchase. The results also showed that there were four groups of underwear benefits sought: sex appeal/individuality, comfort, practicality, and fashion/brand groups. In regard to the group differences, there were significant differences in underwear purchase motives, underwear preferences, store selection criteria, and demographics.
