Eggs are considered an excellent complete food because they contain many major energy sources, including protein. Eggs are one of the most widely consumed foods worldwide, and egg consumption is steadily increasing. Eggs are generally classified according to their quality and weight. Various characteristics of eggs must be considered for the design and effective utilization of equipment used for the transport, processing, packaging, and storage of eggs. In this study, egg surface area, volume, density, etc. were measured according to the grade of the egg. The values of several geometrical properties that were measured tended to increase with increasing egg grade. The smallest grade eggs had the lowest shell thickness and density. The electrical conductivity of the eggshell and its contents was measured with a self-made electrode and equipment. The egg shell showed properties similar to insulators, and as the thickness increased, the electrical conductivity tended to increase. The electrical conductivity of the egg yolk showed almost constant values under all conditions. The electrical conductivity of the egg white and mixture was particularly low at 0.1 kHz. Fouling and electrode corrosion occurred in a low frequency region due to the egg white. In this study, various geometric and electrical characteristics of eggs were measured, and based on this, factors that could serve as new indicators for egg processed production were analyzed and investigated.

Purpose - Eggs are nutritionally complete and one of the most popular natural foods. Moreover, the poultry industry is one of the important food industries. However, early industrialization of the poultry industry on its own did not lead to further development compared to other livestock industries. In this study, we investigate what factors influence consumers' behavior and how consumers' understanding of retail business affects their propensity to consume. This study is different from other studies as it analyzes how the brand names of manufacturers and distribution companies affect the purchasing characteristics or actual purchase behavior of consumers in order to suggest how these manufacturers and distribution companies can increase their competitiveness. Research design, data, methodology - This study conducted a survey of 250 randomly selected egg purchasers in discount stores from January to April 2013. Consumers' purchase tendencies were calculated through frequency analysis. This result was then utilized using cluster analysis to draw a conclusion about which purchase tendency influenced consumers buying three different brands of eggs or whether this tendency really affected consumers. As a result, the outcomes of Hypotheses 2 and 3 were not clear so we drew a conclusion with our analysis of Hypothesis 1. Results - While the outcomes of Hypotheses 2 and 3 did not clearly indicate whether purchasing tendencies affected consumers when buying eggs, our analysis of Hypothesis 1 indicated that consumers were affected by the quality of the eggs rather than exterior factors such as the brand name. Thus, we concluded that it is important to promote the excellence of the quality of the eggs. Usually firms buy eggs from farms and repackage them in order to sell them. In this sense, if consumers were aware of this egg production process, and eggs were fairly distributed to retailers, large retail PB businesses would also be able to enhance their competitiveness. Conclusions - The brand, packaging, retail outlet, and other external features influenced the purchase of eggs to a certain degree, while shelf life, grade of the eggs, cleanliness, and other intrinsic characteristics had more influence. In particular, shelf life was the most important factor influencing purchase. Consumers were influenced not only by intrinsic characteristics of the eggs but also by large-scale producers' brands. Consumers relied upon the brand despite reduced competition because they found it difficult to identify shelf life and/or cleanliness. Small businesses and/or large-scale retailers can remain competitive by maintaining the freshness and cleanliness of the eggs. Further studies need to investigate areas in which consumers' cognition of the product is poor and/or the purchase inclination with regard to less developed industries such as eggs. In this study, the greatest problem was that consumers did not consume in accordance with the current situation as consumers have preferred fresh and clean eggs for a long time compared to purchase decisions based on external brands and/or packaging.

Owing to the rapid growth of hypermarket/discount store formats since 1996, Korean retailing has suddenly attracted the significant attention from researchers. Before the emergence of large scale retailers such as E-Mart, Lotte Mart and Tesco Korea, there were the two retail formats who led the Korean retailing in the modern retailing history: department store and supermarket formats. Nevertheless, there has been little literature concerned about the two retail formats as a case study, while some authors have paid their attention to hypermarket/discount store formats. In addition, when mentioning the development process of retailing history, it is less likely that authors have made an effort to illustrate supermarket retailing history. In order to regard supermarket retailing as part of the Korean retailing, it is interesting to look at a representative supermarket retailer, Haitai, who was one of the subsidiaries of Haitai chaebol. Based on supermarket retailing, the company which was established as a joint venture in 1974 led a supermarket retailing in the Korean modernised retailing history. Before analysing whether Haitai failed or not, the definition of failure should be illustrated. With regard to the term, failure, in the academic world, authors have interchangeably used the following terms: failure, divestment, closure, organisational restructuring, and exit. To collect research data as a case study, the author adopted an in-depth interview method. The research is based on research interviews with 13 ex-staff who left after Haitai went bankruptcy, from store management department to merchandise department. By investigating Haitai's experiences through field interviews, the research found that Haitai restructured organisational decision-making process at the early stage when companies started to modernise organisational charts, benchmarking sophisticated retailing knowledge through the strategic alliance with a Japanese retailer. In respect of buying system, the company established firmly buying functions by adopting central buying system, and further, outstandingly allocated considerable marketing resources to the development of retailer brands with the dedicated team of retailer brand development. In the grocery retailing, abandoning a 'no-frill' packaging concept, the introduction of retailer brand packaging equal to, or better than national brand packaging design, encouraged other retailers to change their retailer brand development strategies. In product sourcing ways, Haitai organised for the first time the overseas sourcing team with the aim of improving the profit margins of foreign products and providing exotic products for customers, followed by other retailers. Regarding distribution system, the company introduced the innovative idea which delivered products ordered by stores directly to each store withboth its own vehicles and its own warehouse in which could deal with dry foods, chilly foods, frozen food, and non-foods, and even, process produce. In addition, Haitai developed many promotional methods to attract more customers like 'the guarantee of the lowest price', and expanded its own business to US in 1996, although withdrew, because of bankruptcy in 1997. Together with POS introduction in 1994, Haitai made a significant contribution to the development of the Korean retailing, influencing other retailers in many aspects. As a case study, the study has provided a number of lessons from Haitai's experiences for academicians and practitioners, suggesting that its history should be involved in the Korean modernised retailing.

Purpose - The purpose of this study is to investigate the difference in the degree of significance and satisfaction perceived by college students and ordinary consumers on the HMR product attributes. Comparison of the difference on HMR product attributes between ordinary consumers and college students who belong to the current and future consumption groups of HMR will provide information for clear marketing strategies and PR on target consumers from the aspects of companies. Also, overall difference on HMR was investigated through IPA(importance-performance analysis) on significance and satisfaction with each product attribute. This result will provide information to food companies that produce or supply HMR products to be supplemented and improved. Finally, IPA was conducted between groups on product attribute to find which difference exists between groups. This result is also expected to provide crucial information to companies as suggested in the first purpose. Research design, data, and methodology - The procedure of analysis is as follows. First, independent sample t-test was conducted on the significance and satisfaction on HMR product attributes. Second, with using IPA, the significance and satisfaction on HMR product attributes of the respondents were checked to investigate marketing strategy direction on overall HRM products. Third, the difference between generations was verified using IPA on the college student and consumer groups. According to this result, the direction of marketing strategy on HRM products was to be proposed to food companies. Results - It was known that consumers consider HMR product attributes statistically and significantly such as nutrient content(nutrition), country of origin, brand, main raw material, packaging, and awareness of manufacturer. They keep after purchase more importantly than college students who considered only volume and price than consumers. In comparison with the difference in satisfaction on HMR product attributes, the college student group was more satisfied than ordinary consumers only in flavor, condition of food additives, and volume. Also, HMR related food companies must maintain taste, cooking method, manufacturing date, expiration date, and safety on current products continuously. Finally, as a result of analysis from the groups, the attributes such as cooking method, manufacturing date, expiration date, and safety were considered significantly with high achievement by the two groups. It was known that college students considered food texture to be important, but consumers considered storage method to be important after purchasing it. Conclusions - There is necessity to differentiate effectiveness of products when releasing HMR products subject to consumers and college students. The result will give great assistance to the improvement of companies, produce or supply HMR products. It will also provide entry strategies on target groups of companies that are planning for entry. The factors that consumers commonly considered not to be significant were brand, package form(appearance), cooking time, and sale(purchase) location, which were found in the comparison with the groups that awareness about manufacturers and storage method after purchase corresponded to college students and that distribution route corresponded to ordinary consumers.

본 연구에서는 저온물류 시스템의 단열용기의 온도유지 성능에 대하여 5℃급 저온 LHM을 배치하였을 때 배치구성 조건에 따른 온도특성을 확인하였다. LHM을 단열용기 내부에 배치하였을 때 6면과 5면에 상/하부 배치 비중에 차이를 두고 외기부하에 따른 내부 공기 온도균일도 및 목표 온도 유지시간을 분석하였다. 단열용기 내부 공기는 상부의 상승온도와 이때 발생하는 밀도차에 의한 공기 대류현상이 온도 성층화를 발생시키고, 균일도를 확보하기 위해 LHM의 상부 배치 비중이 하부보다 컸을 때 균일성이 높고 유지 시간이 오래 지속되는 것을 확인하였다. 다만, 상부 배치 비중을 높이기 위해 하부 배치를 제외한 조건에서 높은 균일성을 보이지만 짧은 유지 시간으로 보여 적정조건으로 알맞지 않다. 결과적으로 단열용기의 단열재 대칭구성과 LHM의 동일한 중량을 배치하여 보냉용기를 제작할 경우, LHM의 전면 배치를 바탕으로 하부에 비해 상부 배치 비중을 늘렸을 때 내부 공기 온도의 분포 균일도와 유지시간 성능을 높이는데 효율적인 방안이라고 판단된다. 저온물류 보냉용기 성능분석에 있어, 본 연구를 기반으로 다른 조건의 상변화 온도와 잠열량을 갖는 다양한 저온영역대의 LHM을 적용한 수치해석을 수행하여 성능 예측 결과를 확보할 수 있고 온도 균일도를 위한 단열 및 잠열 복합 구성 이송 용기의 최적 설계조건 수립에 기여할 것으로 기대된다.

2021년 11월 5일 '유통기한(流通期限)' 대신 '소비기한(消費期限)'을 표시하도록 하는 ｢식품 등의 표시·광고에 관한 법률｣ 시행령과 시행규칙 일부 개정안이 입법 예고되었다. 이에 본 연구는 식품 유형별 소비기한 참고치 설정을 위한 과학적 기반을 구축하고자 과학적 안전계수 산출법을 마련하고, 안전계수를 제시하고자 하였다. 본 연구에서는 온도 남용, pH, 수분활성도, 포장방법에 대해 모의실험을 진행하며 식품 자체의 수명(소비기한)에 영향을 주는 5가지 특성을 1) 수소이온농도(pH), 2) 수분활성도(Aw), 3) 살균 여부, 보존료(항균, 항산화) 함유 여부, 저장성 향상 포장(레토르트, 진공포장, CO₂ 충진, N₂ 충진, 탈산소 제 등), 4) 제품 보관 방법 (냉장, 냉동, 상온, 실온), 5) 멸균 여부로 설정하였다. 수소이온농도(pH) 4.6 이상의 식품은 세균 생장이 용이해 가장 높은 안전계수 값인 0.92를 적용하며, pH 3.5 이하의 강산성 식품은 세균 생장이 중단되고 대부분의 효소반응이 감소하므로 안전계수를 적용하지 않았다(1.0). pH 3.5-4.6 사이의 약산성 식품은 미생물(효모, 곰팡이 포함) 생장이 활발하지는 않지만 가능은하므로 중간값인 안전계수 0.96을 적용하였다. 수분활성도(Aw) 0.91 이상의 식품은 미생물(효모, 곰팡이 포함) 생장이 용이해 가장 높은 안전계수 값인 0.92를 적용하며, Aw 8.0 이하의 건조식품은 세균 생장이 중단되고 대부분의 효소반응이 감소하므로 안전계수를 적용하지 않았다(1.0). Aw 0.8-0.9 사이의 반건조 식품은 세균 생장이 활발하지는 않지만 가능은 하며 진균류(효모, 곰팡이) 생장이 용이하므로 중간값인 안전계수 0.96을 적용하였다. 살균, 보존료(항균, 항산화) 함유 또는 저장성 향상 포장(레토르트, 진공, CO₂ 충진, N₂ 충진, 탈산소제 등) 식품은 미생물(효모, 곰팡이 포함) 오염도 및 생장, 대부분의 효소반응이 감소하므로 안전계수를 적용하지 않았다(1.0). 위와 같은 처리를 하지 않은 식품은 미생물(효모, 곰팡이 포함) 생장이 용이하고 대부분의 효소반응이 촉진되므로 가장 높은 안전계수 값인 0.92를 적용하였다. 저장 온도(냉동, 냉장, 상온, 실온)별 안전계수는 표준온도 편차 값(냉장 0.07, 냉동 0.08, 상온 0.27, 실온 0.01)을 사용했으며, 온도편차 중 낮은 온도는 안전에 영향을 주지 않으므로 온도 편차의 절반인 높은 온도 값만 안전에 영향을 주므로 50%(0.5)를 곱해주고 온도 초과에 미치는 '유통+소비단계' 기여율(85%)인 0.85를 다시 곱해 나온 안전계수 값인 냉장 0.03, 냉동 0.03, 상온 0.11, 실온 0.01을 적용하였다. 냉장식품의 온도남용에 대한 안전계수는 온도남용 시 실제 노출시간(1시간)을 반영해 50%(0.5) 곱하고, 소비자 냉장식품 온도남용 비율인 92.3%(0.923)를 곱해 도출한 0.407 값을 활용한 안전계수 값인 0.96을 적용하였다. 멸균 제품의 경우 안전계수를 적용하지 않았다. 요인별 특성을 고려하여 안전계수에 기여하는 비중과 이를 활용하여 최종 안전계수값을 산출하는 방법(A그룹-O그룹)을 decision tree로 나타냈다. 본 연구는 과학적으로 산출한 안전계수를 통해 소비기한을 제시함으로써 음식물쓰레기 감량과 탄소 중립성 달성에 기여할 것으로 사료된다.

With the increase in online shopping and delivery food consumption since the pandemic, solving environmental problems caused by single-use packaging has become an important issue. 'Upcycling' is a combination of 'Upgrade' and 'Recycle', and it is the rebirth of obsolete or discarded objects by adding new value to them, and there are currently various upcycled products on the market. In order to activate upcycling, consumers' awareness of the environment and their values for consumption are very important. This study aims to investigate the influence of students' environmental concern, environmental experience, and consumption value on their purchase intention of upcycled products. Based on the results of previous studies on environmental concern, environmental experience, and consumption value, hypotheses were set, and a survey was conducted among university students nationwide to test the hypotheses. The results of this study are as follows First, environmental concern has a significant positive effect on purchase intention of upcycled products. It can be seen that the more environmental concerns such as global warming and waste disposal problems increase, the more positive attitudes toward upcycled products increase. Second, the research hypothesis that environmental knowledge will have a positive effect on the purchase intention of upcycled products is rejected. It was found that environmental knowledge is acquired through environmental education and many SNS, but it does not have a direct effect on the purchase intention of upcycled products. Third, it was found that the consumption value of college students has a positive effect on the purchase intention of upcycled products by increasing their positive perception of upcycled products. Fourth, college students' purchase intention of upcycled products has a positive effect on their behavioral intention to purchase upcycled products. The results of the study provide implications for relevant organizations such as universities and companies to effectively design upcycling-related education. It is also expected to have a positive impact on the use of upcycled products by providing basic information on the characteristics of consumers who purchase upcycled products.
