본 연구는 자원이 부족한 중소벤처기업과 비대면 거래의 급격한 증가 속에 많은 관심을 받고 있는 온라인 쇼핑몰의 구매후기 정보 누적이 제품 구매후기의 평점에 어떠한 영향을 미치는가에 대한 분석을 통하여 효과적인 구매후기 정보 노출 방안을 도출하였다. 행동경제학의 주요이론과 소비자 기대불일치 이론을 기반으로 가설을 도출하였고, 실증연구를 위하여 대표적인 온라인 쇼핑몰인 Amazon의 구매후기와 판매자 정보 빅데이터를 활용하여 장단기적 관점에서 구매후기 정보 누적의 영향을 분석하였다. 실증연구를 위하여 Amazon의 378,411개 제품을 대상으로 작성된 9,092,480개의 구매후기를 활용하였고 위계적 회귀분석을 통해 가설을 검증하였다. 분석 결과 구매후기 개수가 늘어날수록 평점 평균은 낮아지는 것으로 나타났다. 최근 구매후기 개수가 많은 제품의 평점이 높은 것으로 나타났다. 제품의 특성은 이러한 영향에 조절효과를 보여주었다. 본 연구는 구매후기와 관련된 연구에 새로운 이론적 기반을 제공할 것이며, 자원의 부족 등으로 온라인 쇼핑몰을 통한 판매에 주력하는 중소벤처기업이 구매후기 정보를 적절히 활용하여 판매성과를 높이는데 도움을 줄 것이다. 또한 온라인 쇼핑몰 관리자에게도 효과적인 구매후기 정보 노출 방안에 대한 실증적 통찰력을 제공할 것이다.

The number and variety of products and services offered by companies have increased dramatically, providing customers with more choices to meet their needs. As a solution to this information overload problem, the provision of tailored services to individuals has become increasingly important, and the personalized recommender systems have been widely studied and used in both academia and industry. Existing recommender systems face important problems in practical applications. The most important problem is that it cannot clearly explain why it recommends these products. In recent years, some researchers have found that the explanation of recommender systems may be very useful. As a result, users are generally increasing conversion rates, satisfaction, and trust in the recommender system if it is explained why those particular items are recommended. Therefore, this study presents a methodology of providing an explanatory function of a recommender system using a review text left by a user. The basic idea is not to use all of the user's reviews, but to provide them in a summarized form using only reviews left by similar users or neighbors involved in recommending the item as an explanation when providing the recommended item to the user. To achieve this research goal, this study aims to provide a product recommendation list using user-based collaborative filtering techniques, combine reviews left by neighboring users with each product to build a model that combines text summary methods among deep learning-based natural language processing methods. Using the IMDb movie database, text reviews of all target user neighbors' movies are collected and summarized to present descriptions of recommended movies. There are several text summary methods, but this study aims to evaluate whether the review summary is well performed by training the Sequence-to-sequence+attention model, which is a representative generation summary method, and the BertSum model, which is an extraction summary model.

Despite a short history, the research on porous coordination polymers is gaining importance in inorganic chemistry thanks to facile synthesis, unambiguous characterization by X-ray diffraction and potentials as high-surface-area materials. Recently, gas sorption properties of various porous materials are under active investigations in order to know whether it is possible to store industrially important gases through physisorption, and porous coordination polymers are one of the most promising candidates for such a purpose. This article reviews two recent papers reporting a series of isomorphous frameworks based on Zn(II), dicarboxylate and diamine ligands and their gas sorption properties.

The development of accelerator science and technology has been accommodating ever increasing demand from scientific community of the beam energy and intensity of proton beams. The use of high-powered proton beams has extended from the traditional application of nuclear and high-energy physics to other applications, including spallation neutron source replacing nuclear reactor, nuclear actinide transmutation, energy amplification reactors. This article attempts to review development of proton accelerator, both linear and circular, and issues related to the proton beam energy, intensity as well as its output power. For related accelerator physics and technical review, one should refer to the recent article in the Reviews of Modem Physics [1]

Genetics has played a pivotal role in increasing the world food production through revolutions in plant and animal sciences. Though the attention on fisheries has been inadequate but the growing importance of modern genetic manipulations and biotechnological innovations to aquaculture has been realized. Recent advances in fish genetics and molecular biology have provided a suite of useful techniques, which have several applications in aquaculture. This paper reviews the advancement in the applications of selection, hybridization, chromosome engineering, sex control, gene transfer and molecular technologies for enhanced aquaculture productivity.
