고객의 요구에 대한 빠른 대응과 유연하고 효율적으로 새로운 제품을 적기에 개발하기 위해서는 제품 플랫폼에 기초한 대량 맞춤이 절실히 요구된다. 이러한 목적을 달성하기 위하여 기업들은 상대적으로 생산비용을 낮게 유지하면서 대량생산의 이점을 유지하고 동시에 고객의 요구사항을 만족시키기 위해, product family를 도입하고 가능하면 작은 변화를 통하여 제품의 다양성을 유지하고자 한다. Product family를 설계할 때 중요한 이슈는 제품의 공통성과 차별성간의 절충점을 어떻게 찾아낼 것인가인데, 이를 위하여 개발된 것이 product family내에서 평가하는 방법이다. 본 연구에서는 product family의 공통성을 평가하기 위해 개발된 대표적인 7가지의 방법을 여러가지 측면에서 비교분석한다. 이를 위하여 두 개 회사의 컴퓨터 마우스 제품군을 대상으로 공통성 평가를 위한 비교연구를 수행하였다. 추가적으로 본 연구에서는 product family를 설계하거나 재설계할 때 공통성 평가지 수의 효과적이고 효율적인 사용방안을 위한 전략도 제시하였다.

Traditional soybean paste from Shandong Liangshan and Tianyuan Jiangyuan commercial soybean paste were chosen for analysis and comparison of their bacterial and fungal dynamics using denaturing gel gradient electrophoresis and 16S rRNA gene clone libraries. The bacterial diversity results showed that more than 20 types of bacteria were present in traditional Shandong soybean paste during its fermentation process, whereas only six types of bacteria were present in the commercial soybean paste. The predominant bacteria in the Shandong soybean paste were most closely related to Leuconostoc spp., an uncultured bacterium, Lactococcus lactis, Bacillus licheniformis, Bacillus spp., and Citrobacter freundii. The predominant bacteria in the Tianyuan Jiangyuan soybean paste were most closely related to an uncultured bacterium, Bacillus licheniformis, and an uncultured Leuconostoc spp. The fungal diversity results showed that 10 types of fungi were present in the Shandong soybean paste during the fermentation process, with the predominant fungi being most closely related to Geotrichum spp., an uncultured fungal clone, Aspergillus oryzae, and yeast species. The predominant fungus in the commercial soybean paste was Aspergillus oryzae.

This study investigated the effects of applying cellulase and starch on the fermentation characteristics and microbial communities of Napier grass silage after ensiling for 30 d. Three groups were studied: No additives (control); added cellulase (Group 1); and added cellulase and starch (Group 2). The results showed that the addition of cellulase and starch decreased the crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and pH significantly (p < 0.05) and increased water-soluble carbohydrate (WSC) content (p < 0.05). The addition of additives in two treated groups exerted a positive effect on the lactic acid (LA) content, lactic acid bacteria (LAB) population, and lactic acid / acetic acid (LA/AA) ratio, even the changes were not significant (p > 0.05). Calculation of Flieg's scores indicated that cellulase application increased silage quality to some extent, while the application of cellulase and starch together significantly improved fermentation (p < 0.05). Compared with the control, both additive groups showed increased microbial diversity after ensiling with an abundance of favorable bacteria including Firmicutes and Weissella, and the bacteria including Proteobacteria, Bacteroidetes, Acinetobacter increased as well. For alpha diversity analysis, the combined application of cellulase and starch in Group 2 gave significant increases in all indices (p < 0.05). The study demonstrated that the application of cellulase and starch can increase the quality of Napier grass preserved as silage.

The purposes of this study were to examine the conceptual structure of shopping value, evaluative criteria of golf wear and store choice behavior, and to investigate the effect of shopping value and evaluative criteria of golf wear on store choice behavior. Data were obtained from 415 men and women aged 20-60 who had purchased golf wears living in Busan. The results of the study were as follows: Shopping value were composed of Hedonic shopping value and Utilitarian shopping value, and evaluative criteria of golf wear were consisted of Size/design.quality, Fitness/appropriateness of use, and Fashionability/brand. Stores choice behavior were composed of Atmosphere/salesperson, Diversity of product/service, Display/assortment, and convenience of location. Hedonic consumers tended to consider the price and display/assortment when they chose golf wear stores, and they were more likely to consider display/assortment mediated by fashionability/brand. But utilitarian consumers perceived less important diversity of product/service when they chose golf wear stores. Consumers who chose golf wear depending on fittness/design and quality patronaged stores offering diverse product/service.

This study analyzed the effect of the intrinsic and extrinsic attributes of gochujang, Korean red chili paste, on purchasing intention and recommendation intention for consumption. Survey participants were female, married, aged 30 - 39 years, and highly educated with graduation from a university. Most participants purchased gochujang 1 - 2 times per year, most commonly at a shopping mall, and acquired information on the gochujang product from an advertisement or sponsored TV shows. For the factor analysis, five variables for intrinsic quality were considered: namely, healthiness, economics, convenience, diversity, and sense, whereas three variables were considered for extrinsic quality: trust, external appearance, and image. The factor analysis also confirmed the correlation between the validity and the reliability of the purchasing and recommendation intentions. The effect of intrinsic quality of gochujang on purchasing and recommendation intentions was tested through a multiple regression analysis. The purchase intention was most significantly affected by healthiness, cost, and convenience. On the other hand, the recommendation intention was most significantly affected by the diversity and, to a lesser degree, by the healthiness of the product. Among the extrinsic qualities, trust of consumers and the product appearance had a significant effect on purchasing intention. Recommendation intention was significantly affected by the appearance. And trust significantly influenced the recommendation. Therefore, a concrete and systematic marketing approach considering these factors.

As new types of medical devices are emerging through convergence with advanced technology, innovative technologies are becoming hot issues in health policy because of their disruptiveness. This study analyzed the innovative medical device management systems in the US, China and Korea. Innovative medical devices have been defined differently depending on the country's management system, but in common, they are defined as products that do not exist or have dramatically improved performance compare to existing products by applying innovative technologies. Innovative medical devices have been supported by regulatory authorities during product development and approval processes. While the US and China have more than 300 products designated as innovative medical devices with diverse functions, application fields, and manufacturing countries considering the initial situation of the implementation for the system, Korea has only 16 products, mainly radiology and diagnostic devices and made in Korea only as innovative medical device. In addition, Korea shows the highest market approval rate of innovative medical devices compare to the US and China, and it is necessary to prepare the approval process in consideration of product diversity.

Purpose: This study is designed to grasp how consumers' beliefs about the lunch box attributes such as healthiness, diversity, price, hygiene, and package eco-friendliness affect consumers' perceived value and purchasing behavior. Research design, data, and methodology: The data were collected from 615 respondents composed of men and women aged 20 to 59 who purchased lunch box products and were sampled using the quota sampling method. An online survey was conducted. The data were analyzed using the measurement model and structural equation model assessment with SPSS 24 and SmartPLS 4.0. Results: First, healthiness, diversity, hygiene, and the price had a significant positive effect on the perceived functional value of consumers, but package eco-friendliness did not significantly affect functional value. On the other hand, healthiness, diversity, price, and package eco-friendliness were found to have a positive impact on consumers' perceived emotional value, but hygiene was found to have no significant effect on emotional value. It was found that functional and emotional values significantly positively affected repurchase intention. Conclusions: This study confirmed that consumers' belief in the product attributes of franchise lunch boxes influenced consumers' perceived value, which thus formed the attitude of consumers and showed a relationship that affects repurchase intention. At the end of this paper, the managerial implications for the franchise lunch box brand, the limitations of this study, and future research directions were presented.
