'Niitaka' (Pyrus pyriforia) has been the major cultivar of the Asian pear since the 1970s, and yielded about 70% of pear production in South Korea in 2002. When Chuseok (Korean Thanksgiving Day) is earlier than the fruit maturation period, farmers seek to advance the harvesting date to keep pace with the increase in consumer demand caused by the holiday. However, unripened fruit is of suboptimal marketable value because the flesh has a low soluble solid content, the fruit color is not attractive, and stone volume is high. Compost treatment can enhance soil microbial activity and affect soil chemistry, which may accelerate fruit maturation and allow an earlier harvesting date. Therefore, we examined the effect of 2 years of compost application on the fruit quality of Asian pear trees grown under conventional management conditions. The Hunter "L" and "a" values were higher in compost-treated fruit, which also showed greater sweetness and lower acidity than did conventional fruit. The stone volume was reduced and fruit calcium concentration was increased by compost treatment. Therefore, compost treatment may advance fruit harvesting owing to the increased marketability afforded by attractive skin color, sweetness, and reduced stone volume.

This study investigated the physicochemical and sensory characteristics of yanggaeng prepared with various amounts of Chrysanthemum zawadskii powder (as ratios of 0.5%, 1%, 1.5%, 2% to the total materials). The result displayed that the $^{\circ}Brix$ value, pH of yanggaeng decreased significantly with the addition of Chrysanthemum zawadskii powder. Increasing the amount of Chrysanthemum zawadskii powder in the yanggeng tended to increased acidity. In chromaticity determination, the values of lightness (L) showed a decrease. However, the value of redness (a) increased by increasing levels of Chrysanthemum zawadskii powder. Texture measurement scores in terms of hardness, springiness, and adhesiveness for yanggaeng showed that sample groups were lower than those of the control group. Cohesiveness and chewiness were higher in the additive group than in the control group. DPPH radical scavenging activity and nitrites cavenging activity were significantly increased Chrysanthemum zawadskii (p<0.001). The DPPH content was highest in the 62.40% Chrysanthemum zawadskii yanggaeng. As Chrysanthemum zawadskii powder increased, antioxidative activity also increased. Sensory evaluation scores in terms of color, odor, taste, texture, and overall preference of groups with 0.5% of Chrysanthemum zawadskii powder did not show any significant differences when compared to the control group. Based on the above results, this study suggests that the addition of 0.5% Chrysanthemum zawadskii powder may be the best substitution ratio for yanggaeng.

In this research, we performed a SWOT analysis to analyze the feasibility of cultivating tropical fruits in Korea, using the mango as a case study. The opportunities for domestic tropical fruit (mango) cultivation are that the domestic cultivation environment is improving due to global warming, the consumer market is expanding due to the increase in domestic demand, and some local governments are supporting the cultivation of tropical fruits as a new high-income crop. The strengths are that it is possible to produce high quality fresh fruits in Korea and that they are still distributed in small quantities, so they can be differentiated from imported ones. There are regular customers and the mango is recognized as a medicinally functional fruit. The threats are that the price competitiveness of imported goods is likely to be further strengthened due to the implementation of the FTA and that it is difficult to cope with the unpredictable climate changes, such as heavy snowfall and extremely cold weather. The weak points are that the initial investment cost is high, the operating costs such as heating bills are also very high, and there is no supply system for the chemicals, fertilizers and cultivation technology required for tropical fruits. In order for tropical fruits such as mangoes to become major fruits, we must make full use of these strengths and opportunities while, at the same time, complementing the weaknesses and eliminating the threats in the value chain.

The problem of choosing the right product that will best fit a consumer's taste and preferences extends to the field of electronic commerce. However, e-commerce has been able to create a technological proxy for the social filtering process, known as online recommender systems (RSs). RSs aid users in filtering products and decisions on matters relating to personal taste. RSs have the potential to support and improve the quality of the decisions consumers make when searching for and selecting products and services online. However, most previous research on RSs has focused on the accuracy of the algorithms, with little emphasis on user interface and perspectives. This study identified transparency and feedback as possible ways to effectively evaluate RSs from the user's perspective. Thus, this research focused on examining and identifying the roles of transparency and feedback in recommender systems and how they affect users' attitudes toward the system. Results of the study showed that both transparency and feedback positively and significantly affected perceived trust, perceived value of the process, and perceived enjoyment. Furthermore, we found that perceived trust, perceived value of the process, and perceived enjoyment positively and directly affected users' intentions to use/reuse a recommender system.

Purpose - This study was conducted to present a study on the perception and satisfaction with the brand agricultural products targeted at consumers who use a lot of local products. According to the data of 2011, the total number of the brand agricultural products of Korea is 5,291 with various kinds. Research design, data and methodology - The survey shows that the brand agricultural products are being used by some specific people. However, it can be a useful idea which can help the consumption of brand agricultural products to be expanded if we understand how consumers' recognitions are different between various groups. For an empirical Analysis, the response data of 110 adult patients residing in the metropolitan area were used and conducted with a factor analysis, frequency analysis in order to ensure the validity and conducted a regression analysis and correlation analysis using SPSS statistical program. Results - According to the analysis, it showed consumers with an interest in brand agricultural products are 40-50 age housewives and the middle class of about 5 million won in monthly income more than 3 million won with a college education. As for consumers' purchasing status, all the subjects said that they had experienced buying brand agricultural products and the level of satisfaction for them was very high. Relatively, consumers' satisfaction level with high income and education is high. And recognition of the brand agricultural products was found mainly goes through word of mouth. The age and income are very important factors in customers' repurchase for brand agricultural products. The result of the analysis for the influences on brand agricultural products of customer satisfaction suggests even if the recognitions for safety, quality, and value are vital factors, the recognition of quality doesn't influence on brand agricultural products statistically and significantly. It was analysed if there were any differences between recognitions by group to brand agricultural products, that is to say recognition of safety, quality and value and the result can be summarized as follows. There are all statistical significant differences depending on their age, educational background and income. In the case of 30 or 40 aged, as they got the education level of college and graduate school and earned relatively high income, most customers have positive recognition on the brand agricultural products. This implies the group which can buy and consume the brand agricultural more easily has much more positive recognition. Conclusion - The results of this study shows consumers' brand awareness and satisfaction with brand agricultural products are affected by their age and income level. The purpose of this study is to find the information that can help brand agricultural products markets to be expanded by understanding the factors which encourage consumers to behave repurchase as well as customers' various levels of recognition to the brand agricultural products. The survey says that brand agricultural products are being used by some specific people.

Purpose - The movie market has the characteristics of being a perfectly competitive market as well as a pure monopolistic market at the same time. This is because there are competitors in the industry but prices, although not fixed, have not changed a lot. Price competition may not have spread, but the competition is focused on artistic value, and the degree of box office success is most important. The artistic value is determined in the course of the production process. However, the degree of box office success is dependent upon the marketing manager. The marketing strategy represents the difference in the standard or quality of the movie. Inherently, the marketing manager adopts the entertainment strategy based on the quality of the foundation of the completed movie. At this time, the marketing manager knows the pertinent information (high quality/low quality) regarding the movie. This research study tries to reveal what should be the reasonable movie marketing expense, dependent on the quality of the movie. Research design, data, and methodology - Using a game scenario with different market players, the goal of the research analysis is to find out the following. First, the marketing expense is determined to maximize the profits after film production. Second, after the production costs are already committed, the manufacturer gets to choose the marketing level. At this time, there will be a profit maximization point, considering the competition. The premise of the research is as follows: if it is a good movie of quality, positive word of mouth increasing the audience continuously slows down the speed of the demand curve. If the movie quality is bad, the negative word of mouth decreasing the audience gradually hastens the speed of the demand curve. On the marketing side, when the manufacturer invests heavily in the marketing expense of the movie, consumer expectations increase to drive up the audience numbers. On the other hand, it is difficult to improve the profits excessively. When the manufacturer invests in marketing a little bit, the marketing expense is only relatively committed, therefore a lot of demand cannot be gained. Results - If a fixed market share is in a competitive situation, a low quality manufacturer expends relatively more marketing expense. If the situation assumes two manufacturers spend the same for the cost of production, the high quality manufacturer takes more profit. If the manufacturer expends less marketing budget to save costs, the optimum profit cannot be achieved since the other party (opponent) grabs the initial market share. Conclusions - In conclusion, investment is essential for market share to increase. We must refrain from a zero-sum game and have models where the game participants pursue the creative profits together. In the current film industry, there is the dominating logic of winner and loser but we have to create a film industry environment where the participants can be altogether satisfied and live together.
