The cinema circuit is facing a digital, network, and mobile age, which expands non-theater accessibility to movies. Application platforms are situated as the most competitive business model that provide digital content such as games, music, books, and movies. Consumers can acquire content-related information not just offline, but online as well. Therefore, item information provided by application platforms is required. The information provided by application platforms consists of richly descriptive information such as storyline summary, consumer reviews, and related articles, while non-descriptive normative information covers data such as sales ranking, release date, genre, rental or purchase cost, domestic/foreign classification, consumer rating, number of consumer ratings, film rating, and so on. In this study, we surveyed and analyzed statistically the correlation between real-time sales ranking and other comparable non-descriptive information.

This paper proposes a new communication system for e-learning applications to mitigate the negative impacts of COVID-19 where the online massive demands impact the current commu-nications systems infrastructures and capabilities. The proposed system utilizes high-altitude platforms (HAPs) for fast and efficient connectivity provision to bridge the communication in-frastructure gap in the current pandemic. The system model is investigated, and its performance is analyzed using adaptive antenna arrays to achieve high quality and high transmission data rates at the student premises. In addition, the single beam and multibeam HAP radio coverage scenarios are examined using tapered uniform concentric circular arrays to achieve feasible communication link requirements.

최근 COVID-19 확산과 함께 온라인 쇼핑 시장의 규모가 지속적으로 증가하여 다양한 온라인 거래 플랫폼이 시장에 등장함에 따라 많은 소상공인이 플랫폼에 입점하고 있다. 이처럼 최근 소상공인의 플랫폼 활용이 크게 늘어나면서 적정 수수료에 대한 이슈가 제기됨에 따라 플랫폼 활용과 수수료에 대한 사회적 논의의 필요성이 제기된다. 현재 수수료에 대한 논의는 대부분 부정적인 측면에서 특정 사례 중심으로 이루어지고 있으며 플랫폼의 활용 가치와 수수료를 종합적으로 고려한 체계적인 논의는 부족한 실정이다. 따라서 본 연구는 플랫폼 서비스 활용 가치와 수수료 비용을 함께 고려하여 플랫폼 수수료에 대한 체계적이고 종합적인 이해를 목적으로 한다. 이를 위해 플랫폼 서비스별 경제적 가치를 추산하여 세부적으로 분석하였다. 온라인 플랫폼 사용이 활발한 배달 서비스, 이커머스 두 업계를 선정하고 판매자가 플랫폼 서비스를 이용함으로써 발생하는 기대수익 변화에 주목하였고, 판매자의 플랫폼 입점 여부, 서비스 이용 여부 등 시나리오별로 추산한 매출과 비용을 기반으로 기대수익을 비교분석하였다. 연구 결과, 플랫폼 입점과 플랫폼 서비스 활용은 매출 상승과 비용 절감을 가능하게 하며, 이는 판매자의 기대수익에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구를 통해 플랫폼 수수료를 플랫폼 서비스 이용과 이에 따른 가치 획득에 대한 사용료 관점으로 이해하고 이를 기반으로 플랫폼 서비스와 수수료의 경제적 가치를 추산하여 플랫폼 서비스 활용 가치와 비용을 종합적이고 체계적인 논의로 확대하고자 한다.

The emergence of systems biology in the 21st century is changing the paradigm of biomedical research. Whereas the reductionist approaches focus on components rather than time or contexts, systems biology focus more on interrelationships, dynamics, and contexts. The key ideas of the systems biology shares much with the philosophy of Korean Medicine(KM) and therefore, the paradigm shift is shedding light on understanding the mechanism of action of KM at system level. In this article, I provide a guide to learning systems biology for KM researchers using online learning resources. Thanks to the recent development of MOOC(massive open online courses) and other online learning platforms, learners can access to plenty of high-quality resources from top-tier universities in the world. I expect this guide help researchers to employ systems biology methods into their KM researches, and will lead to the development of future curricula for training "bi-lingual" experts, KM and computational approaches.

The online education platform market is developing rapidly after the coronavirus infection-19 pandemic. As school classes at various levels are converted to non-face-to-face classes, interest in non-face-to-face online education is increasing more than ever. However, the majority of online platforms currently used are limited to the fragmentary functions of simply delivering images, voice and messages, and there are limitations to online hands-on training. Indeed, digital transformation is a traditional business method for increasing coding education and a corporate approach to service operation innovation strategy computing thinking power and platform model. There are many ways to evaluate a computer programmer's ability. Generally, piecemeal evaluation methods are used to evaluate results in time through coding tests. In this study, the purpose of this study is to propose a comprehensive evaluation of not only the results of writing, but also the execution process of the results, etc., and to evaluate the programmer's propensity habits based on the programmer's coding experience to evaluate the programmer's ability and productivity.

Corona 19 minimizes face-to-face contact, and online untact platforms are emerging in the medical sector. However, there are potential risks of medicine expiration, medicine misuse, and responsible materials management for secure delivery. In this paper, we investigate three key functional requirements for online pharmacy, and design the blockchain based online pharmacy to meet the requirements. To protect the patient's privacy and to ensure tamper-free traceability, we incorporate the multi-level access authentication scheme for each participant (governments, medical circles, and patients). We show that our system guarantees patient's privacy without further system modification.

Given the increasing information overload among users of online review websites, understanding the manner in which cognitive costs are reduced and efficient information is made reliable has become increasingly important. This study targets a unique consumer review design and explores how reviews from an external peer-to-peer site embedded in an online travel agency (OTA) website influence subsequent evaluation behaviors. The empirical results indicate that (1) embedded external reviews with a high average valence tend to strengthen the influence of the positive evaluation ratio while diminishing the effect of the review volume, and (2) embedded external reviews with a large variance strengthen the positive effect of the review volume while weakening the effect of the positive evaluation ratio on subsequent positive evaluations. The findings provide practical insights for consumers and online platforms.

최근 모바일 플랫폼 기반 비즈니스의 증가와 함께 온라인 숙박 예약 시장이 커지고 있다. 본 연구에서는 서비스 품질에 대한 불확실성이 높은 온라인 숙박 예약 플랫폼에서 부정적 리뷰의 대응 전략이 숙박 업체의 성공에 미치는 영향을 살펴보았다. 국내 최대 숙박 예약 플랫폼에 등록된 856개의 모텔을 대상으로 호스트의 대응 전략의 숙박시설 성공에 대한 효과를 확인한 결과, 부정적 리뷰에 대한 호스트의 답변수가 많고(적극성), 답변 속도(적시성)가 빠를수록 성공에 정(+)의 영향을 주는 것으로 확인되었다. 또한 두 가지 대응 전략에는 정(+)의 상호작용 효과가 있음을 보였다. 마지막으로 평판 하락에 따른 호스트의 대응 전략을 확인한 결과, 평판 하락 발생 시 부정적 리뷰에 대한 대응 적극성의 효과는 증가하였다. 본 연구는 숙박업체의 성공에 효과적인 호스트의 대응 전략을 규명하였으며, 평판 하락에 따른 호스트의 대응 전략의 효과성을 확인한 연구라는 점에서 학술적, 실무적 의의가 있다.
