This study has been performed to investigate the stress distribution around defects that behave as stress concentrators. Besides, the effect of stress interaction effects on the initiation of primary cracks were also investigated by rotary bending fatigue tests which were performed with specimens drilled micro surface defects and the stress distribution was analyzed using Finite Element Method. In addition, the stress interaction effects around defects and cracks were investigated- by comparing the results of experiments and F.E.M. The results obtained are summarized as follows ; 1) Area which slip and micro cracks initiated at micro surface defects is between the maximum shear stress points and this area is over than ±30˚the maximum stress point along the defect edge. 2) The stress interaction effect for the small size defect is larger than that of large size defect when the interval between them is near. 3) Interval which there is no shear stress interaction effect analyzed by F.E.M. is larger than that of experimental results.

Enterprises have to first establish special relations with their customers through effective communication in the market environments of a society with diversified environments that makes it easy to get commodities. In view of that, brand identity is getting more and more important. Especially, in the package design, study in B.L makes its efficiency identified and it is understandable that the image of a brand with excellent package design could stimulate people to buy merchandise. A commodity increases its good impression by expressing its uniqueness, thereby forming brand loyalty. Meeting the emotional propensity to consume by groups with desire to buy by providing the brand image with effective impact, that is, a strategy of appealing to the emotional feelings of consumers would play a great role in the business culture. In this connection, the results from this study will be summarized as follows: First, brand naming is the one of the strongest differentiation factors. The leading brand in the appreciation of brands is preferred by consumers. It means it is more frequently exposed to people, who will prefer it more. High degree of recognition of a brand by consumers means that the image of the brand name has been clearly transmitted to people. Second, in the aspect of the sense of vision, differentiation strategy consists in development of B.I. As shown on the results of investigation, although B. I. cannot work as a direct factor for the preference of brand, it is evaluated that a decisive factor in the degree of brand preference is greatly correlated with B. I. strategy of package design. Since preference to a brand is formed by connection with various factors, consistent development of image through comprehensive review and improvement can give contribution to increase of preference to a brand. Third, in differentiation strategy for package design, colors, the aesthetic aspect and appreciation of the beautifulness work as the most core factors. It is appraised that more people are tempted to purchase commodities by package designs, and many people agree on importance of it. However, since it is evaluated that satisfaction in package design is not so high now in the Korean market, which means package design must be improved in the future in Korea. As it is indicated that colors and aestheticism are the important parts in which consumers have the most interest as proper package design factors, it is required that package designs must be diversified through market segmentation. Fourth, B. I must be gotten stronger to enhance brand loyalty. Brand loyalty should be upgraded by review of connection with the aspect of the sense of vision and the aspect of marketing as well through market segmentations fit to life patterns of groups with desire to purchase commodities. Fifth, local brands should focus on becoming better than leading brands, just not to try to come up with them. Because B. I. and package designs of most of the local brands remains in the state of OEM or planetary redesigning of foreign brands, it is definitely required that both Korean designers and companies have to create unique Korean identity depicting excellent Korean cultural value. Sixth, all we have to do is in the future establish marketing approach to meet the requirements of various buying groups and develop marketing strategy based on design marketing concept. In addition, it is hoped that the results from general marketing aspects will be compared and reviewed and then integrated through a thorough study.

The Influence of Household Types on Food and Grocery Store Choices

김만근,이윤금,김성숙 한국농촌경제연구원 2018 농촌경제 Vol.41 No.S

This study examines the effect of household type on food and grocery store choices using the 2016 KREI Consumer Behavior Survey for Food (CBSF) data. This study further investigates factors (e.g., socio-economic characteristics, consumer capacities, and store attributes), in relation to food and grocery store choices. There exist significantly different store choices among the household types. The marginal effects from the multinomial logit model show that one-person households are more likely to choose supermarkets as their primary food and grocery stores. In contrast, relatively young (age under 45) multi-person households are more likely to shop their food and groceries in large discount stores. Both elderly (age 65 and up) one-person and multi-person households prefer to go to supermarkets as well as traditional markets. Except for elderly households, all the households are less likely to shop in traditional markets. The implications for growing one-person and elderly households are discussed.

The Effects of Household Differentiation and Population Aging on Juice Consumption in Korea

김만근(Man-Keun KIM),김화년(Hwa-Nyeon KIM) 제주대학교 관광과경영경제연구소 2021 産經論集 Vol.41 No.1

Purpose: This study investigates the impact of increases in single-person households and aging population on fruit juice consumption in Korea. Juice consumption in Korea has been steadily decreased. It may be mainly due to the health concerns, as there are a lot of sugar in fruit juices. We hypothesize that single-person households and the aging population may have affected the decrease in juice consumption. Research design, data and methodology: We used data from the 2018 Consumer Behavior Survey for Food. The survey question asks respondents about beverage choice as “Select all the beverage you drink frequently at home” and multiple responses are allowed. Because the preferred beverage is not identified and selections of the beverage are not mutually exclusive, the logit model is adopted respectively for each beverage choice. Results: Single-person household is negatively related to the choice of fruit juice. It implies that single-person household drinks fruit juice less frequently. Age group has the negative relationship with choices of fruit juice. Conclusions: The decrease in juice consumption will not only affect the beverage market, but also the fresh fruit market. Therefore, the beverage industry should strategically develop healthy juices such as adding probiotics to rebound juice consumption.
