This study was conducted to understand the type of use and satisfaction of delivery food by Chinese and Korean students. In December 2019, Korean and Chinese students living in Gyeonggi Province were analyzed using SPSS. The average number of food deliveries was 1~2 times a month and used 30.7% of the Korean students and 21.8% of the Chinese students. As for how to order food for delivery, 62.2% of Korean college students took up mobile apps, and 49.0% of Chinese students took up mobile phones. In terms of satisfaction after using delivery food, Korean students scored 3.89 points for taste and 3.74 points for using a neat and convenient packaging container, while Chinese students showed the highest score of 3.69 points for past eating experiences and 3.65 points for taste. As for the factors influencing the satisfaction after using the delivered food, the food quality satisfaction (β=0.518) for Korean students and favorable menu factor (β=0.533) for Chinese students were found. Therefore, it is judged that it is necessary to continuously improve the quality, service, convenience and diversity of delivered food, and health and safety factors in order to improve the delivery patterns and satisfaction of college students.

To solve the internal security problem such as human error and bad faith, the automation of computer system management is significant. For this purpose, we focus attention in the automation of Mail Delivery Service. Today, requirement for reliable mail delivery system becomes larger and larger. However, existing systems are too strict about their configuration. Hence, we propose the method based on Reinforcement Learning (RL) to achieve proper MX record ordering. A measure on validity of the design of system, such as network topology number of servers and so on, is also obtained as side benefit. In order to verify the usability of the presented method, we did on a small model of mail delivery system. As a result, we show that RL is available for determination of the proper MX record ordering. Additionally, we suggest that it is also available for comparing validity of setting of MTA and the network design.

The purpose of this study was to evaluate the level of SCM activities and the logistics performance by SCM of the three company types in fashion industry· fabric suppliers, apparel manufacturers, and retailers. The level of SCM activities was estimated through the examination of seven factors: commitment and leadership of a top management, flexibility of management, understanding of demand characteristics, integrated management organization, information system, cooperative partnership and communication and exchange of opinion. The logistics performance was measured by improvement in customer service(on time delivery ratio of products, returning rate, treat ratio for A/S, order fill rate, substitute providing capability for being out of stock) and delivery cost reduction. Through questionnaire survey, a total of 214 data for 108 companies of three company types were collected: 46 for 40 fabric suppliers, 123 for 64 apparel manufacturers and 45 for 4 retailers. The analysis of SCM activity levels showed that fabric suppliers had higher degrees in the factor of understanding of demand characteristics, and apparel manufacturers had higher degrees in the factor of information systems. For retailers, the factor of communication and exchange of opinion represented higher degrees. The study on relationship between the SCM activity levels and logistics performance showed that the SCM activity factor of understanding of demand characteristics greatly improved a substitute providing capability for being out of stock in fabric suppliers, and information system improved a substitute providing capability for being out of stock, on time delivery ratio of products and order fill rate in apparel manufacturers. In retailers, the SCM activity factor of understanding of demand characteristics decreased returning rate highly and improved on time delivery ratio of products. The study results showed that SCM activities in fashion industry brought more improvement in customer service levels rather than in delivery cost reduction.

본 논문에서는 3GPP2 IMT-2000 서비스를 위해 기존 음성 및 인터넷 인프라를 수용할 수 있으며, IMT-2000망에서 Mobile-IP over IMT-2000 멀티미디어 응용 서비스를 제공하는데 필수적인 MDA(Multicast Delivery Agent)-기반의 Mobile-IPv6 멀티캐스트 알고리즘을 제안하고 이를 분석한다. IMT-2000 시스템 모델은 PDSN(Packet Data Serving Node) 또는 IWF(Interworking Function)기능이 각 기지국에 존재하는 분산된 모델을 사용한다. 새로운 프로토콜의 핵심요소는 멀티캐스트 데이터그램 전달 경로를 줄이기 위해 MDA (Multicast Delivery Agent)를 도입한 것이다. 제안된 프로토콜은 현재까지 제안된 이동망에서 멀티캐스트 지원 기법들과 비교하여, 짧은 라우팅 경로 및 이동 호스트에 근접한 노드에서 이동 호스트로의 직접 데이터그램 전송을 통하여 성능 향상을 기대할 수 있다. 특히, 터널링 수 및 멀티캐스트 데이터그램의 평균 라우팅 길이가 감소하고, 멀티캐스트 데이터그램의 트래픽 부하도 감소한다.

국내 택배시장은 과거 몇 개의 업체에서 독점해왔으나 현재는 대기업들과 수많은 중소기업들이 참여하고 있어 경쟁이 심화되고 있다. 우편물의 신속한 배송과 운송비용의 최소화는 매우 중요하며 이를 위하여 운송거리의 최단 거리화가 우선 필요하다. 본 논문은 전국의 주요 도시에 배치된 우편집중국을 기하적으로 가장 짧게 연결하는 교환 센터의 최적 위치를 찾는 방법을 제시한다. 송전계통의 routing, 배전선로망의 최적화 등에 이용되고 있는 Steiner Tree이론을 최단거리 우편물 운송망 구축에 적용하였다. Steiner Tree이론으로부터 선정된 위치에 교환센터를 설치할 경우, 운송비를 절감하여 경영수지를 개선할 뿐 아니라 신속한 배달을 최우선으로 하는 택배 시장에서 우위를 점할 수 있을 것으로 기대된다. Steiner Tree 이론은 차기 초고압 선로를 최단거리로 연결하는 전력소의 위치선정 등에도 활용될 수 있을 것으로 사료된다.

Purpose - The purpose of this study to explore factors consumers prioritize when purchasing seafood online. The originality of the study lies on adopting AHP-based approach in analyzing prioritized purchasing factors of seafood online. Design/methodology/approach - A survey was conducted targeting Korean consumers who have purchased seafood online. AHP method was applied to rank factors consumers prioritize before making decision. Findings - First, product's factor ranked first among other high level factors including delivery service, seller, online platform. Second, sanitation, taste, country of origin ranked first, second, third respectively, within product's factors. Third, safe delivery, timeliness, information accuracy ranked first, second, third respectively, within delivery factors. Fourth, consumer reviews, consumer response ability, promotion ranked first, second, third within seller factors. Fifth, Personal information management system, credibility, user-friendliness ranked first, second, third, within online platform factors. Research implications or Originality - To activate seafood online market, it is crucial to assure consumers that the seafood is well managed in a sanitary way from the production site to table. Existing government programs such as seafood traceability system, HACCP, and cold-chain infrastructure needs improvement. Due to highly perishable characteristic of seafood, delivery factors matter when purchasing online. Online platforms needs to continue to improve delivery service. Seafood products are mostly not branded and without objective information about their properties. Creating quality classification and seafood brands are likely to help consumers chose seafood online.

본 연구는 아동·청소년 관련 시설 및 기관을 이용하는 초, 중, 고 학생들의 이용 실태와 중복 이용 경험을 분석하여, 효과적인 아동·청소년 서비스 전달체계를 제안하기 위한 목적을 지니고 있다. 이를 위해, 아동과 청소년이 이용하는 공공 서비스 전달체계를 중심으로 초, 중, 고 학교급별 차이를 통계 분석과 네트워크 분석방법을 활용하여 분석하였다. 주요 연구결과에 따르면, 일반 시설(기관) 이용율에서 학교급별 차이가 나타난 곳은 주민자치센터, 청소년수련관(수련원), 건강가정지원센터, 보건소, 시청·도청, 군청·구청, 교육청이었다. 복지 시설(기관) 중에서는 위(Wee)센터, 위(Wee) 스쿨, 지역아동센터에서 학교급별 차이가 나타났다. 네트워크 연결 중심성 분석에서는 초등학생은 보건소, 중학생은 청소년 수련관, 고등학생은 주민자치센터가 가장 높게 나타나, 자체 및 중복 이용자 수가 가장 높은 것으로 조사되었다. Concor를 이용한 구획화 결과에서도 동일한 시설(기관)이라도 학교급에 따라 서로 다른 기관 간 연계가 이루어지고 있는 것으로 나타났다. 이러한 연구결과를 토대로 향후 아동·청소년 서비스 전달체계의 질적 개선을 위해서, 생애주기적 특성을 고려한 통합 게이트웨이 구축과 개인별 시설(기관) 이용 데이터베이스 개발을 제안하였다.
