본 연구에서는 급증하는 배송 서비스 수요에 맞춰 더 신속하고 최저 비용으로 근거리 배송을 가능하게 하는 알고리즘을 제안하고자 한다. 본 연구에서 제안하는 알고리즘에서는 배송원으로 지하철 승객을 물류 이동에 참여시킨다. 이때 승객은 이동 경로와 일치하는 배송 물류를 선택할 수 있다. 그리고 서비스 이용자의 입장에서는 현재 근처에 경로가 일치하는 배송원을 선택할 수 있다. 이때 배송원 추천은 TF-IDF&N-gram과 BERT를 결합한 텍스트 유사도 측정 방식으로 진행된다. 따라서 기존 택배 시스템과 달리 소비자-배송원 간의 man-to-man 방식으로 양방향 선택을 지원한다. 탑승 중인 승객을 물류 이동에 참여시킨다는 점에서 비용 최소화와 배송 기간 단축을 모두 보장할 수 있다. 더하여 운송 측면에서도 특별한 기술을 요하지 않으므로, 일자리 입지가 축소된 노동자들에게 경제 참여 기회를 제공할 수 있다는 점에서도 의의가 있다.

In this paper, we present an abstract object-oriented plat-form model .suitable for the real-time distributed telecommunication system. The proposed platform is constructed upon the extended version of the real-time, distributed operating system, SROS(Scalable Real-time Operating System), that is developed at ETRI and successfully operated in the ATM switching system for several years. The object-oriented software development and maintenance methodology will resolve the current software crisis in the area of telecommunication and switching systems due to the everlasting maintenance about the huge amount of the existing software and the ever increasing needs for the better and new communication services. In general, an object-oriented software platform realizes the object-oriented methodology and possesses many good aspects like high productivity, better reusability, easy maintenance, et at. The platform is also designed to present the distributed multimedia service in addition to real-time event delivery. Recently, we have been implementing a couple of prototype bated on the proposed platform. Reflecting the evaluation results from these prototypes, the final platform specification will be determined.

Small satellites represent an emerging opportunity to realize a wide range of space missions at lower cost and faster delivery, compared to traditional spacecraft. However, small platforms, such as CubeSats, shall increase their actual capabilities. Miniaturized electric propulsion systems can provide the satellite with the key capability of moving in space. The level of readiness of miniaturized electric propulsion systems is low although many concepts have been developed. The present research intends to build a flexible test platform for the assessment of selected small propulsion systems in relevant environment at laboratory level. Main goal of the research is to analyze the mechanical, electrical, magnetic, and chemical interactions of propulsion systems with the modern CubeSat-technology and to assess the performance of the integrated platform. The test platform is a 6U CubeSat hosting electric propulsion systems, providing mechanical, electrical and data interfaces, able to handle a variety of electric propulsion systems, thanks to the ability to regulate and distribute electric power, to exchange data according to several protocols, and to provide different mechanical layouts. The test platform is ready to start the first verification campaign. The paper describes the detailed design of the platform and the main results of the AIV activities.

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.

Fashion brands communicate with consumers through the use of fashion films that are effective in the delivery of the image. This is because digital media (such as fashion films) are popular and accessible as well as effective in attracting people's attention. The reasons why fashion films have become a new fashion media among many others is becuase they are based on an existing platform. This study will examine offline platforms of fashion film: flagship store, fashion exhibition, and fashion show. The offline platform of a fashion film is a physical space where a fashion film can be exhibited and viewed as a medium that can effectively convey fashion film to consumers. As a research method, the concept of an offline platform of fashion film is established based on a literature review of fashion films and platform that is followed by an empirical case study. The study results show that the offline platform of a fashion film is in the progress of turning into an autotelic space where the consumption of such culture as cinema and theater has become possible.
