This study was conducted to examine the consumption realities of processed food and the perception of food labeling with targets of university students attending schools in Daegu and Gyeongbuk areas. The reason for buying processed food was because it is easy to cook. As for the number of using processed food, it was answered that everyday dairy products, noodles, breads and snacks for 3~4 times a month, and meat processed foods, canned foods, sauces and frozen foods for 2~3 times a month. With regard to selecting processed products, both male and female students answered with taste and price first, barely considering the safety and nutritional elements. It turned out that they check the price, expiration date and country of origin in order upon buying processed foods. Most of them recognized food labeling, but answered that they checked it sometimes in order to check the 'expiration date' and the 'calories'. They were aware of the food nutritional contents indication. It was turned out that male students check it for nutrients and female students for weight control. The effect of the processed food indication was that it is easy to choose the necessary foods for health and as well as for comparing the food with other products. The satisfaction of the food labeling system was mediocre. The results indicated that the food indication system needs to be educated or promoted.

Purpose - The ultimate purpose of this research is to analyze the influence of personal disposition on shopping value and behavioral intention by expanding the theory of planned behavior (TPB). Research design, data, and methodology - An attempt was made to examine the effects of personal disposition (reflecting duty-free shop characteristics) on three selective actions of consumers - compulsive buying, variety seeking, and price sensitivity. We conducted a questionnaire survey with the users of airport duty-free shops, downtown duty-free shops (offline), and online duty-free shops. In total, 410 copies of the questionnaire were analyzed using a structural equation model. Results - According to the results, compulsive buying, variety seeking, and price sensitivity significantly affected shopping value. Shopping value and subjective norms both had significant effects on attitude, the major variable in the TPB, and attitude had the greatest effect on behavioral intention, followed by subjective norms and perceived behavioral control in descending order. Conclusions - This study has academic implications in that it extends the existing theories of planned behavior and applies it to consumer characteristics and shopping value. It has practical implications as well in that it provides basic data that can be used to establish concrete marketing strategies for duty-free shop owners targeting segmented markets by closely examining customer desires.

The main purpose of this paper is to propose an alternative system of the distribution of OTC drugs in Korea. We first investigate the characteristics and the regulations on the distribution of the Korean medicine market and compare it with some foreign countries. We also examine the buying behavior of Korean customers. We propose three different alternatives. A passive policy is to expand the range of OTC drugs. Another one would be to amend the relevant laws. An active alternative is to arrange a separate organization to control the distribution of OTC drugs. The time and the execution of the proposed policies could vary.

Dasik is a type of Korean traditional confectionery that is kneaded with various grains, nuts or herb flour and honey and then pressed with a decorative press. Soybeans are a rich in protein, lipids, dietary fiber, minerals and fat soluble vitamins. Spirulina is a functional food that contains protein, lipids, carbohydrates, minerals, vitamins, dietary fiber and pigments. In this study, soybean Dasik containing spirulina was developed in an attempt to provide an easy method of incorporating spirulina into daily dietary life. In addition, we evaluated the quality characteristics of the soybean Dasik with spirulina that was developed here. Specifically, 0, 10, 20 and 30% spirulina was added to the soybean powder that was used to prepare soybean Dasik. Soybean Dasik that contained 30% spirulina had a higher moisture content and lower hardness when compared to other groups. In addition, the L, a and b value decreased as the level of spirulina increased. Furthermore, the antioxidant activity of soybean Dasik increased according to the increase in the addition of spirulina. Specifically, the $IC_{50}$ values of the DPPH and hydroxyl radical scavenging activity of the control group were 76.6 mg/mL and 100.7 mg/mL, respectively, whereas these values were 26.3 mg/mL and 32.9 mg/mL, respectively, in Soybean Dasik that contained 30% spirulina. When a sensory evaluation was conducted, the overall preference decreased as the level of added spirulina increased. When the buying intension was evaluated, the control group had the highest score (7.8), followed by that of the Dasik that contained 20% spirulina (7.2) The buying intention was lowest for the Dasik that contained 30% spirulina. In conclusion, Soybean Dasik that contained up to 20% spirulina would be maketable.

The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

School is an excellent place for children to loam environment-conscious behavior and for teachers to bring up environmental education. School has a plenty of teaching materials such as school building, pond, school forest, waste and school supplies. Especially, the environmental education for and with school supplies can be very effective, as it is mostly the first products for children to learn the buying and consumption in their daily life. In this study we conducted a survey on the environmental attitude of two groups of 5th graders towards environmentally friendly school supplies. The experimental group received environmental education on school supplies and the control group did not. The survey results showed that almost 50% of the children did not consider the environmental impact, but rather the price, design and function when buying the school supplies. However, more than 70% of children were willing to use the recycled school products, implying that they are aware of environmental Issues and want to contribute to the preservation and improvement of the environment. The children recognized paper/notebooks and paints/crayons as the major environmental problems. Writing appliances such as pens, pencils, highlighters and markers were also considered as environmental concerns, since most of them are made of plastics and they are not easily biodegradable nor refillable. We also exemplify a lesson-plan for environmental education program on school supplies and make suggestions to encourage the use of those eco-friendly school materials.

This study investigates a buyer-supplier supply chain, in which a buyer delegates the production process to a supplier as in many practices. The consumer's buying intention and overall supply chain performance are affected not only by the buyer's decision on sales price but also by the supplier's decision on product quality. Therefore, the buyer has a motivation to control the supplier's quality investment. Among various incentive schemes that the buyer can adopt in practice, we consider a revenue-sharing contract and investigate its unique characteristics. By comparison with a typical wholesale price contract, we reveal that the revenue-sharing contract can enhance supply chain's overall performance, including quality, demand, and profits of not only overall supply chain but also each player. We contribute to the academia and the supply chain practice by providing important guidelines in adopting incentive schemes and effectively managing product quality in a supply chain.
