The main purpose of this study is to investigate the effect of housewives' dietary awareness and habits on the reduction and recycling of food waste products. We have done statistical analyses of 501 questionnaires answered by housewives living in Taegu city. The results are as follows: The dietary awareness is significantly different according to the housewives' ages. The group of above 50's age and the group of housewives and their husbands with a lower education level have a more traditional awareness and eating up habits. Also the younger group, and those with a higher education level who grew up in a big city have a more progressive dietary awareness. But the younger, higher income, small family, higher education level groups, and also employed housewives, produced more food waste products than the other groups, The groups thsose have traditional or rational awareness concerning dietary awareness, and those with good eating up and accurate cooking habits turned out to have more affirmative effects on the reduction and recycling of food waste products.

Purpose - This study examines Chinese P2P investment decision processes from a behavioral economics approach. Research design, data, and methodology - We analyze the online P2P investment product purchase decisions of 241 respondents in China, March 2015 to May 2015. T-tests were conducted to determine whether the framing effect influenced investor investment preferences. The Association Rule was used to identify the framing effect of respondent demographic characteristics on joint decisions regarding stable or risky investment products. Results - There are significant differences between the two groups (positive framing and negative framing) and their product-choosing behavior. In the positive framing group, female investors, young investors, investors with non-financial occupations and with limited or no experience, preferred stable P2P investment products. In contrast, in the negative framing group, investors with extensive investment experience preferred risky investment products. Conclusions - The framing effect influences investor choices in online P2P investment products. It is necessary to implement comprehensive supervision and full information disclosure regarding P2P investment products. P2P investment websites can also adopt different marketing strategies according to investor gender and age.

This study investigated on enzyme production in the digestive organs of the native termite (Reticulitermes speratus) in Milyang, Korea. Four types of major cellulases [EG (endo-1,4-${\beta}$-glucanase), BGL (${\beta}$-glucosidase), CBH (cellobiohydrolase) and BXL (${\beta}$-1,4-xylosidase)] were present in the digestive organs of the termite. The strong enzyme activity for BGL was found from the native termite, and also shown that the enzyme was distributed in the salivary gland, foregut, and hindgut. BXL, which breaks down hemicellulose near the amorphous region, was detected mainly from salivary gland, foregut, and midgut. However, CBH was distributed mainly in the hindgut. Meanwhile, EG which degrades cellulose, was found mainly in the hindgut and salivary glands. These facts indicate that celluases production patterns are differ from different sites compare to the same species found in Japan, suggesting that enzyme production in the digestive organs of termites is changed according to their habitats.

Price acceptability has become an important issue in the current fashion market. This study explored diverse factors that affect price acceptability (level of acceptable price and range of acceptable price). Stimuli photos of fashion products (i.e., bag, shoes, and jacket) were developed and used for online experiments with 3,000 female consumers. Important results included factors that affected the price acceptability of fashion products were price-quality relation, price concern, and product attribute perception. The results showed that female consumers depended more on price-quality relations, more positively perceived product attributes, and were less sensitive to price; in addition, they tended to have a higher level of acceptable price as well as a wider range of acceptable price for fashion products. These results were consistent across all experiments with different fashion items (i.e., bag, shoes, and jacket). Based on the results, factors that influence the price acceptability were revealed. Marketing practitioners need to more actively consider implying advertising strategies that emphasize the advancement of product attributes such as quality for highpriced products.

Disposable protective coveralls that cover the entire face and body are essential for operations in contaminative or dangerous environments. This research studied disposable protective coveralls on Korean market in order to improve the products that agricultural workers wear. We investigated the size specifications of 22 disposable protective coverall products sold in Korean markets and analyzed how well the size specifications cover Koreans' sizes by comparing and analyzing the size specifications with Korean body measurements and Korean standards for protective clothing. We analyzed the consistency, regularity, and fitness to body measurements of Koreans for each size by measuring the sizes of 15 different parts for 22 products each. Current disposable protective coverall products for the Korean market are unsuitable for Korean body measurements, especially women's. It was expected that wearers would be unable to choose products that fit their bodies well just by the offered size specifications due to a lack of regularity between the measurements for each size. In this result, it was assumed that the development of KS standards and the coverall pattern that reflect the body measurements of Koreans are needed.

This study was designed to identify the purchasing practice on the bakery products by the female university students in Seoul and Kyunggi area. Total 262 questionnaires were used for the analysis among 285 responses. The results showed that 50.76% of the respondents bought the bakery products 1∼3 times a month mainly for supper or snacks. The most favored bakery products were bread, danguaja bbang, cake, pie and jori bbang, and there was a signigicant difference in the preference of bakery products by the type of dwelling (p<0.001). Students with non-food science major significantly preferred bakeries as light meals (p＜0.01). Students with food science major liked bread, jori bbang, cake and pie, but the non-food science majors liked bread, sweat red-bean bread and sandwich (p＜0.05). Depending upon the housing status and the major of the respondents, there was a signifcant difference in the purchase factor like nutrition, taste, size and sanitation of the store (p<0.05), while the purchasing frequency was not affected by those factors (p＜0.05). As to the question if there is a room for improvement, different housing status influenced significantly the respondents in citing the factors like business hours and service, and the shape of product and service(p＜0.05).

As today's business environment has become more and more competitive, forward as well as backward flows of products among members belonging to a supply chain have been increased. The backward flows of products, which are common in most industries, result from increasing amount of products that are returned, recalled, or need to be repaired. Effective management for these backward flows of products has become an important issue for businesses because of opportunities for simultaneously enhancing profitability and customer satisfaction from returned products. Since third party logistics service providers (3PLs) are playing an important role in reverse logistics operations, the 3PLs should perform two simultaneous logistics operations for a number of different clients who want to improve their logistics operations for both forward and reverse flows. In this case, distribution networks have been independently designed with respect to either forward or backward flows so far. This paper proposes a mixed integer programming model for the design of network integrating both forward and reverse logistics. Since this network design problem belongs to a class of NP-hard problems, we present an efficient heuristic based on Lagrangean relaxation and apply it to numerical examples to test the validity of proposed heuristic.

CC (Common Criteria) requires collecting vulnerability information and analyzing them by using penetration testing for evaluating IT security products. Under the time limited circumstance, developers cannot help but apply vulnerability analysis at random to the products. Without the systematic vulnerability analysis, it is inevitable to get the diverse vulnerability analysis results depending on competence in vulnerability analysis of developers. It causes that the security quality of the products are different despite of the same level of security assurance. It is even worse for the other IT products that are not obliged to get the CC evaluation to be applied the vulnerability analysis. This study describes not only how to apply vulnerability taxonomy to IT security vulnerability but also how to manage security quality of IT security products practically.

To protect the damages or the disasters caused by overheating of industrial electric equipments or electric home appliances, a temperature sensitive thermal fuse is generally used in those equipments. Thermal fuses cutoff the current flow when the temperature of the electric equipments are abnormally overheated and over the certain temperature. Therefore thermal fuse is one of the most important elements in the sense of safety. Thermal fuses are classified into two types according to thermally sensitive materials, a low temperature melting alloy and an organic chemical compound. Domestic products of thermal fuses are now only with an organic chemical compound. Domestic products tested by using cutoff test and aging test etc. are satisfied UL specification. It's shown that the accuracy and the precision of the domestic products are as good as those of the overseas products obtained UL mark. However, some of domestic products show the reclosing problem which is mainly related the safety. This problem should be solved to make the reliable thermal fuses. In this paper, our Interest is to find out the causes of reclosing. In the comparison between thermally sensitive materials occurred reclosing and those occurred no reclosing, the test effects show that the characteristics of emitting heat and absorbing heat are different.
