COVID-19는 커피산업에도 영향을 주고 있다. 이에 새로운 소비 트렌드인 언택트 소비가 증가하고 있으며 언택트 소비를 대표하는 온라인 채널과 배달 어플리케이션을 활용한 소비가 일상화되고 있다. 커피산업에서도 최소한의 접촉만으로 주문이 가능한 드라이브스루, 스마트오더 시스템을 갖춘 커피전문점의 이용이 증가하고 있다. 그러나 언택트 서비스의 대부분이 프랜차이즈에서 선점하고 있는 반면, 개인 커피전문점에서는 차별화된 서비스로 고객과 소통하며 직접서비스를 제공하는 매장들이 많다. COVID-19 감염의 장기화와 함께 전염병으로부터 자유로울 수 없는 현시대의 커피전문점에서는 배달서비스에 대한 고민을 하지 않을 수 없다. 이에 본 연구는 커피배달 서비스에 영향을 미치는 요소들을 분석하였다. 연구결과 COVID-19의 영향으로 커피배달 서비스와 함께 정기배달 서비스 또한 증가하였다. 커피를 다양한 방법으로 즐기고자 하는 소비자들의 홈 카페 이용 증가로 정기배달 서비스가 커피배달 서비스에 중심적인 역할을 하게 될 것이다.

최근 커피전문점이 급격히 늘어남과 동시에 커피 전문점에서 공부나 작업을 하는 사람들이 많이 나타나게 되었으며, 커피전문점에서는 고객 회전율, 수익 등에 문제로 고객들의 매장 이용에 관한 분석이 요구되기 시작하였다. 이러한 분석을 위해 영상 분석, QR 코드 인증, 블루투스 비콘 등의 방법들이 제안되었으나, 사생활 침해 문제, 낮은 정확성 등의 문제점이 있어 활용이 쉽지 않다. 따라서 본 연구에서는 이 문제점을 해결하며, 보다 정확한 매장 내 혼잡도 정보를 제공하기 위해 고주파 신호 기반 혼잡도 측정 시스템을 제안한다. 고주파 신호는 블루투스 신호를 대치하며, 신호의 전달 범위가 매장 내로 한정되어 정확도를 높일 수 있는 장점이 있다. 제안 시스템의 성능 검증을 위해 블루투스 기반 혼잡도 측정과 비교 실험을 진행하였고, 그 결과 제안 방법이 보다 높은 정확도를 나타내었다. 즉, 제안 방법은 커피 전문점에서의 혼잡도 정보 제공 및 통계처리에 효과적인 유용한 서비스가 될 것이다.

To raise the industrial competitiveness in the field of ship-building, it is crucially important that the yard should use production facilities and working space effectively. Among the related works, the management of tremendous blocks' number, the limited area of assembly shops and inefficient personnel and facility management still need to be improved in terms of being exposed to a lot of problems. To settle down these conundrums, the various strategies of block arrangement on the assembly floors have been recently presented and in the results, have increasingly began to be utilized in practice. However, it is a wonder that the sampled or approximated block shapes which usually are standardized projections or the geometrically convex contour only have been prevailed until now. In this study, all parts including the panel, stiffeners, outer shells, and all kinds of outfitting equipment are first extracted using the Volume Primitive plug-in module from the ship customized CAD system and then, the presented system constructs a simpler and more compact ship data structure and finally generates the novel projected contours for the block arrangement system using the adaptive concave hull algorithm.

To show the recognition of hand-sanitizer, we studied the answers of research questions where we got from the northern part of Seoul and Kyunggi Province. We had categorized two groups both industry-related people who work in restaurants, hygiene service shops, whole sales, government organizations, PC shops, factory-department stores and non industry-related people who work in schools, general offices for this study. 1. Hand sanitation level: Over 60% people washed hands 6 times a day. The group using water and soap was much bigger than the group using water for washing hands. For drying, people preferred wipe tissue, towels, clothes, non drying in that order. 2. Recognition of hand sanitizer and its usage experience: Most people(66.5%) did not know what hand sanitizer is, but they have positive attitude if they use this machine. 3. Place of hand sanitizer: The proper places to install were such public places as hospitals, restrooms, and restaurants. The fifties-group was the most frequently hand washing generation with over 9 times a day. 4. Comparison of recognition for hand-sanitizer by male and female: There were different results in each evaluation item by either male or female. The frequency and method of hand washing showed high in males, while females observed hand sanitization, installation requirements, installation areas, home installation, etc more than anything else.

Flow Shop with Multiple Processors(FSMP) scheduling involves sequencing jobs in a flow shop where, at any processing stage, there exists one or more identical processors. Any methodology to determine the optimal mean flow time for this type of problem is NP-complete. This necessitates the use of sub-optimal heuristic methods to address problems of moderate to large scale. This paper presents global lower bounds on FSMP mean flow time problems which may be used to assess the quality of heuristic solutions when the optimal solution is unknown.

This study focused on analysis of the satisfaction level of specialty shops for environment-friendly agricultural products (EFAP). To analyze the satisfaction level of EF AP, a series of household surveys were conducted. Questionnaire was prepared on the basis of the SERVQUAL model and the structural equation modeling was made on the basis of the contents surveyed. The main results of this study are summarized as follows. Firstly, tangibles structured with store clearance, neat uniform, information and others is the factor of service quality satisfaction. Secondly, reliability structured with service practice, problem solving, and service in accurate time is the factor of service quality satisfaction. Thirdly, assurance structured with the reliability of employees, sufficient knowledge of employees, courteous and good manner is the factor of service quality satisfaction. Fourthly, responsiveness structured with prompt service, voluntary help, customer response service and the like is the factor of service quality satisfaction. Fifthly, the sympathy structured in interest for each customer, provision of service in time convenient to use, encountering the customers with genuine feeling are the factors of service quality satisfaction. And sixthly, the service satisfaction factors would influence on the consumer behavior factors.

목적: 본 연구는 안경원에서의 안경용 초음파세척기를 이용한 소프트렌즈 세척 실태를 조사하고 세척용기를 달리하였을 때의 단백질 제거 효과를 비교하기 위하여 수행되었다. 방법: 서울시 소재 75개 안경원을 대상으로 소프트렌즈 세척 실태에 관한 설문조사를 실시하였다. 또한 인공누액을 사용하여 소프트렌즈에 인위적으로 단백질을 침착시킨 후 세척용기를 달리하여 안경용 초음파세척기로 세척한 후 단백질 잔존량을 측정함으로써 세척효율을 비교하였다. 또한 반복적인 초음파 세척으로 인한 소프트렌즈의 표면과 습윤성 변화를 분석하였다. 결과: 안경원에서 콘택트렌즈 세척에 안경용 초음파세척기를 이용하는 주목적은 신속함 때문임을 확인하였다. 세척용기로 플라스틱 렌즈 용기와 유리병 렌즈용기를 사용하고 안경용 초음파세척기로 소프트렌즈를 세척한 경우 유리병 렌즈용기를 사용하였을 때 세척효율이 높은 경향을 보였으나 유의성 있는 차이는 아니었다. 한편 반복적인 초음파 처리로 인하여 소프트렌즈의 표면과 습윤성의 변화가 나타남을 관찰할 수 있었다. 결론: 안경용 초음파세척기 이용 시 세척용기로 플라스틱 렌즈용기와 유리병 렌즈용기의 사용이 모두 효과적이었지만 반복적인 초음파 세척 시에는 세척용기를 사용하였다 하더라도 초음파로 인한 소프트렌즈의 변성이 우려되므로 주의를 기울여 사용하여야 것이다.

This study was performed to analyze the preferences and actual use patterns of university students (96 males and 187 females) for bakeries in the Gyeongju area of Korea. A total of 283 questionnaires were used for the examination and statistical analyses were completed using SPSS Win (14.0) by descriptive analysis and $x^2$-tests. The most favored bakery products were prepared items such as sandwiches and toast. Most of the respondents (92.9%) typically used bread for snacks, and the main places of purchase were well-known bakery shops (38.5%) in which females preferred well-known shops more than males. In addition, the respondents liked milk (79.9%) and jam (39.7%) as the beverage and food, respectively, to eat with bread. When choosing bread, the main selection point was taste (80.2%) and the cost per person per visit was usually 1,000~5,000 won (63.3%). The consumption frequency rate revealed that 49.1% of the students consumed bread as a snack, while 24.8% consumed bread with other foods 1~2 times a week. In the case of purchasing bread as a snack, females had more purchases than males (p<0.05). Students who lived in their own home (p<0.001) with a commute time to school greater than 30 minutes (p<0.001) had the highest number of bread purchases as a snack. The most important point for bread purchase was hygiene (4.60). Overall, for the development of bakeries in the Gyeongju area it seems imperative to address the bakery shop environment, including such aspects as hygiene, price, and new bread product development for students.

Mass customization utilizes the new computer technologies, supply chain management, product information management, and some level of customization of the product for the individual customer. This study aimed at grasping the actual conditions of mass customization of domestic men's suit industry and the use of MTM CAD program. The MTM apparel production programs that are used by five leading men's suit manufacturers in Korea were compared. The results of the study showed that most of the manufacturers produced mass customized men's suits to supply extraordinarily large or small size suit based on the individual order. The information listed on an order sheet used at shops was not necessarily corresponding to the information in the MTM CAD program that is use for production of suit ordered from the shop. The pattern data base on the MTM CAD program are constructed based on the sizing system of individual manufacturer. The most manufacturers translated the customer's body dimensions into difference between the standard pattern and the customer's needed adjustment.
