Since Amazon announced plans to deliver goods to customers using drones, many countries and companies have become interested in drone logistics delivery services and have begun testing drone delivery for various goods based on service scenarios. Whenever there is news of a successful drone delivery anywhere in the world, people increasingly expect the delivery of goods through drones. Although delivery services using drones are currently in a trial-and-error stage, given technical limitations and institutional and social constraints, a complete shift to drone logistics delivery is not yet possible. In anticipation of the drone logistics delivery service, recent drone delivery tests, current service trends, and requirements for drone delivery service will be examined.

Food delivery service combined with IT technology and HMR (Home Meal Replacement) are rapidly growing due to the COVID-19. Recently, the demand for salads along with HMR has increased among office workers in their 20s and 30s who are interested in health and beauty. Freshcode is a food startup with 6 years of experience that started selling salad products through O2O service. Freshcode applied for a patent for a service that collects orders from nearby areas and delivers them on the same day to a designated delivery address 'FCOSPOT' to save shipping costs. In March 2021, in recognition of the growth potential of the regular delivery service, Freshcode received an investment of 6 billion won in Series A. This study may have practical implications to early-stage startups and scale-up stage startups through a longitudinal case study on the growth of a single company. As for the research method, the lean startup methodology and lean canvas were used in the early stage of startup. In particular, the process of the build-measure and learn feedback-loop, which is the core of lean startup methodology, was applied to each major decision-making step. In the scale-up stage after 5 years, the business model canvas was used to schematize the growth as a food online O2O platform to verify continuous innovation. This case study has three main findings. First, the idea of 'FCOSPOT' was successfully implemented through the Lean Startup methodology. Second, Freshcode demonstrated the scalability of the differentiated business model of shared base delivery O2O. Third, a key factor of success was the digital integrated communication operation strategy that maximizes the experience for the created customers.

The post-production of smart farming defines the stage that the final products are delivered from producer to consumers via market on ICT network. It deals with the process of product packaging and distribution from producer to consumer with marketing strategy. This focus on reference model for post-production service including specialization, centralization of product delivery, and just-in-time delivery, and marketing system on the network. It defines a significant function component on post-production stage. The producer plays a significant role in economy being one of the main contributors to the many customers. This articles suggest the effective product distribution service which requires delivering the right product, in the right quantity, in the right condition, to the right place, at the right time, for the right cost, and encompassing global marketing based on ICT network, will be provided[1].

Supply chain management (SCM) is an area that has recently received a great deal of attention in the business community. While SCM is relatively new, the idea of coordinated planning is not. During the last decades, many researchers have investigated multi-stage inventory problems. However, only a few papers address the problem of cost-optimal coordination of multi-stage inventory control with respect to service measures. Even published approaches have a shortcoming in dealing with a delivery lead time consisted of a shipping time and a waiting time. Assumed that there is no waiting time, or that the delivery lead time is implicitly compounded of a shipping time and a waiting time, the problem is often simplified into a multi-stage buffer allocation and a single-stage stochastic buffer sizing problem at all installations. This paper presents a simulation-based heuristic algorithm and a comparison with others for the problem that cannot be decomposed into a multi-stage buffer allocation and a single-stage stochastic buffer sizing problem because the waiting time ties together all stages. The comparison shows that the simulation-based heuristic algorithm performs better than other approaches in saving average inventory cost for both Poisson and Normal demands.

Recently, there has been an active service that provides customized news to news subscribers. In this study, we intend to design a customized news service system through Deep Learning-based Social Network Service (SNS) activity analysis, applying real news and avoiding fake news. In other words, the core of this study is the study of delivery methods and delivery devices to provide customized news services based on analysis of users, SNS activities. First of all, this research method consists of a total of five steps. In the first stage, social network service site access records are received from user terminals, and in the second stage, SNS sites are searched based on SNS site access records received to obtain user profile information and user SNS activity information. In step 3, the user's propensity is analyzed based on user profile information and SNS activity information, and in step 4, user-tailored news is selected through news search based on user propensity analysis results. Finally, in step 5, custom news is sent to the user terminal. This study will be of great help to news service providers to increase the number of news subscribers.

We first develop a value ecosystem framework to model the SDP(Service Delivery Process) of web services. Since the web service has been evolving from the basic web architecture (e.g., traditional world wide web) to a prosuming platform based on virtualization technologies, the proposed framework of the value ecosystem focuses on capturing the key characteristics of SDP in each type of web services. Even though they share the basic elements such as PP(Platform Provider), CA(Customization Agency) and user group, the SDP in the traditional web services (so-called Web1.0 in this paper) is quite different from the most recent one (so-called Web2.0). In our value ecosystem, users are uniformly distributed over (0, ${\Delta}$), where ${\Delta}$��represents the variety level of users' preference on the web service level. PP and CA provide a standard level of web service(s) and prosuming service package, respectively. CA in Web1.0 presents a standard customization package($s_a$) at flat rate c, whereas PP and CA collaborate and provide customization service with a usage-based scheme. We employ a multi-stage game model to analyze and compare the SDPs in Web1.0 and Web2.0. Our findings through analysis and numerical simulations are as follows. First, the user group is consecutively segmented, and the pattern of the segmentations varies across Web1.0 and Web2.0. The standardized service level s (from PP) is higher in Web1.0, whereas the amount of information created in the value ecosystem is bigger in Web2.0. This indicates the role of CA would be increasingly critical in Web2.0: in particular, for fulfilling the needs of prosuming and service customization.

택배물류는 택배화물을 택배서비스 요청자가 요구하는 장소까지 직접 배달해 주는 것으로, 택배 기업별로 화물 분류 방식, 업무방식, 그리고 관리하는 정보가 서로 다르고, 비정형 데이터로 인해 상호 호환성을 지원할 수 없다. 종이 운송장 사용으로 개인정보 유출에 대한 문제와 오류 정보로 인해 정확히 화물은 전달하는데 추가적인 시간과 물류비용이 발생되기도 한다. 택배 비즈니스 환경은 무인택배, 신기술(사물인터넷 등)이 도입되는 등 변화되며, 사용자들은 택배 운송 신청부터 수취까지의 과정에 대한 현황 및 상태를 알고 싶어 한다. 그러므로 택배화물 안전 배송을 위한 단일화되고 통합된 운송장 정보가 필요하며, 택배화물 집하/운송/인도 등의 단계에서 적합한 정보를 관련 주체 간에 원활히 제공되어야 한다. 본 논문에서는 택배화물 운송서비스 신청, 집하, 운송, 분류, 인도 등의 단계별 정보를 수집, 가공, 처리한 정보를 비즈니스 처리, 비즈니스 협업, 비즈니스 트랜잭션 간에 발생하는 업무 흐름에 대한 정보로 명시하고 이 정보를 근간으로 택배화물용 전자 운송장을 위한 표준 프로세스와 정보 모델을 정의하였다. 정의된 표준 모델을 통해 택배물류 주체 간 정보 유통 및 공유가 용이할 것이며, 종이 운송장으로 인한 위험이 감소됨으로 인해 국민생활 안전을 증진할 수 있게 될 것이다. 더 나아가 택배업체의 업무 효율성이 증대되는 등 다양한 이해당사자 관점에서 국민 편익을 도모할 수 있을 것으로 판단된다.

사회서비스의 공급체계에 대한 연구는 매우 제한적이며 학문적 연구 성과는 사회서비스 제공현장의 확장속도를 충분하게 따라가지 못하고 있다. 연구는 현재의 사회서비스 공급체계에 대한 연구의 현황을 확인하고 새로운 연구와 정책방향을 모색하고자 하였다. 분석논문은 총 79편으로 구성되었으며 분석틀은 분석차원, 분석기준 그리고 분석내용으로 구분을 하여 빈도와 교차분석을 하였다. 연구는 다음과 같이 정리할 수 있다. 첫째, 사회서비스 공급체계의 품질관련 평가 모델이나 품질 인증에 대한 적극적인 연구가 필요한 시점임을 확인하였다. 둘째, 사회서비스 관련 연구의 확대를 위해 사회서비스 예산에 대한 중앙정부와 지방정부의 규모, 개별 사회서비스 제공기관의 관련 자료 등의 공개가 필요함을 보여주었다. 셋째, 사회서비스 공급체계 연구 확대를 위해 사회서비스 예산 배분, 인구 특성, 형평성 그리고 지역 정보 등을 활용한 사회서비스 수요에 대한 예측 관련 연구가 필요함을 보여주었다. 마지막으로 공급과잉에 의한 서비스의 질의 감소 현실을 고려하여 개별 사회서비스 공급 기관의 진입 규정에 관한 연구도 필요함을 알 수 있었다.
