  • Online consumer reviews have become the most important basis for online shopping and product sales. Fake reviews are generated to boost sales because online consumer reviews play a vital role in consumers' decision making. The prevalence of fake reviews violates the regulations of the online business environment and misleads consumers in decision making. Thus, the present research investigates the effects of reviews' linguistic characteristics (i.e., analytical thinking, authenticity) on review fakeness. Specifically, this research examines whether (1) the level of analytical thinking is lower for fake (vs. genuine) reviews (hypothesis 1) and (2) the level of authenticity is lower for fake (vs. genuine) reviews (hypothesis 2). This research analyzed user-generated hotel reviews (genuine reviews, fake reviews) collected from MTurk. Linguistic Inquiry and Word Count (LIWC) 2022 was adopted to code review contents, and the hypotheses were tested using logistic regression. Consistent with the hypotheses 1 and 2, the results indicate that (1) analyticial thinking is negatively associated with review fakeness; and (2) authenticity is negatively associated with review fakeness. The findings provide important implications to identify fake reviews based on linguistic characteristics.

  • Recent progress in molecular biology has made it possible to transfer genes of interest into cells and target tissues of living animals. This enables one to manipulate phenotype of cells and whole animals in selected and intended ways. The consequence of such gene transfer attempts have been the production of various types of "transgenic" animals that cannot be classified by classical nomenclature of exclusively either "transgenic" or "nontransgenic". Emphasis was placed on characterizing two transgenic categories, i.e., "transfectgenic and somatotransgenic" and "genuine transgenic" animals basically from a view point of their use for therapeutic purposes. Current state of art and possible solutions for problems encountered at present are discussed.

  • With the rapid development in network, graphic technology, and digital technology, content industry is emerging as an important industry for new cultural development and economic development. The development in digital content technology has remarkably expanded the generation and distribution of contents, thereby creating new value and extending into a large distribution market. However, the ease of distribution and duplication, which characterizes digital technology, has increased the circulation of illegal contents due to illegal copying, theft, and alteration. The damage caused by this illegal content is severe. Currently, a copyright protection system targeting online sites is available. By contrast, no system has been established for offline companies that sell offline genuine content, which compete with online companies. The demand for content of overseas tourists is increasing due to the Korean wave craze. Nevertheless, many offline content providers have lost competitiveness due to illegal content distribution with online companies. In this study, we analyzed the case and status of similar copyright certification systems in Korea and overseas through previous research and studied a system to certify the offline genuine contents business. In addition to the case analysis, we focused on interviews obtained through in-depth interviews with the copyright stakeholders. We also developed a certification framework by establishing the certification domain, certification direction, and incentive of the certification system for offline businesses with genuine content. Selected certification direction is ethical, open, inward, store, and rigid (post evaluation). This study aimed to increase awareness among consumers about the use of genuine content and establish a transparent trading order in a healthy content market.

  • Domestic CM market has continued to grow, and the CM services in the international market is evaluated as a high value-added area. However, CM services are currently being challenged to perform its genuine CM roles because of the limitations by government's CM policies, market size, business functions, and technology capabilities. In order to identify the issues for revitalization of CM, this study analyzed the history of CM studies through a thorough review of the previous literatures that have been published since the enactment of CM policies in 1996. Based on this literature review, it is expected to suggest strategies that could improve current immature CM systems.

  • The proliferation of online customer reviews has completely changed how consumers purchase. Consumers now heavily depend on authentic experiences shared by previous customers. However, deceptive reviews that aim to manipulate customer decision-making to promote or defame a product or service pose a risk to businesses and buyers. The studies investigating consumer perception of deceptive reviews found that one of the important cues is based on review content. This study aims to investigate the impact of the information amount of review on the review truthfulness. This study adopted the Information Manipulation Theory (IMT) as an overarching theory, which asserts that the violations of one or more of the Gricean maxim are deceptive behaviors. It is regarded as a quantity violation if the required information amount is not delivered or more information is delivered; that is an attempt at deception. A topic modeling algorithm is implemented to reveal the distribution of each topic embedded in a text. This study measures information amount as topic diversity based on the results of topic modeling, and topic diversity shows how heterogeneous a text review is. Two datasets of restaurant reviews on Yelp.com, which have Filtered (deceptive) and Unfiltered (genuine) reviews, were used to test the hypotheses. Reviews that contain more diverse topics tend to be truthful. However, excessive topic diversity produces an inverted U-shaped relationship with truthfulness. Moreover, we find an interaction effect between topic diversity and reviews' ratings. This result suggests that the impact of topic diversity is strengthened when deceptive reviews have lower ratings. This study contributes to the existing literature on IMT by building the connection between topic diversity in a review and its truthfulness. In addition, the empirical results show that topic diversity is a reliable measure for gauging information amount of reviews.

  • People increasingly rely on sources of information from E-commerce reviews. Product reviews is an important determinant of potential customers' buying choices. They are also utilized by product manufacturers to find problems of their products and to collect competitive intelligence information about their competitors. Unfortunately, it is well-known that many online product reviews are not made by genuine costumers of products. Reviewers could write some undeserving positive reviews to promote or fake negative reviews to defame some certain product, and we call them fake product reviews. Fake product review detection makes an attempt to detect fake reviews and removes them to restore the truthful ones for readers. To the best of our knowledge, there is still less published study on this problem. In this paper, we make a survey and an attempt to give a brief overview on fake product review detection. The related work of fake product review detection is presented including web spam and spam email. Then some methods to detect fake reviews are introduced and summarized. The trend of fake product review detection is concluded finally.

  • This paper was intended to evaluate environmental policies of South Korea and compare its environmental sustainability with other Eastern Asian countries in terms of some sustainability measures. To meet the purpose, the paper is composed of three parts: a brief and critical review of Korea's current environmental policies, comparison of its sustainability with other Eastern Asian countries in terms of well-known environmental sustainability indices, and comparison in terms of a less well-known alternative measure. Korea's environmental policies as stipulated in "Green Vision 21", "Green Korea 2005" were evaluated in light of OECD EPRK 2006. Korea's environmental performance is then compared with other countries based on such environmental sustainability indices as EF, ESI, EPI and EVI. Unfortunately the well-publicized indices to measure sustainable development (SD) seem to fail in measunng SD and in providing comparability, because it does not base on the genuine concept of SD. Therefore, we tried to suggest an alternative measurement in terms of sustainability quantity (SQ), which is presented for South Korea and her major trading partners, such as USA, Japan and China.

  • This study investigates Korean consumers' general perception on brand authenticity, tests the influences of authenticity determinants on the evaluation of fashion brand authenticity and compares the influences in terms of brand category (luxury/non-luxury). A three-stage methodological approach was adopted: (1) A literature review identifies authenticity determinants and generates measurement items. (2) A preliminary study uses a quantitative survey (n=50) to purify the determinants. (3) A quantitative consumer survey (n=150) identifies general perceptions on brand authenticity by measuring the perceived relevance of brand authenticity on determinants and explores the influence of determinants on authenticity evaluations using purified measurements of authenticity determinants. The results of general perception on brand authenticity show that Korean consumers deem authentic brands as honest, sincere and socially responsible. The results indicate obvious differences between luxury and non-luxury brands towards the influence of perceived authenticity determinants (genuine, consistent, original, traditional and authoritative) on authenticity evaluation of luxury/non-luxury brands. In non-luxury brands, only 'genuine' and 'consistent' have significant effects that are similar to the results of the general perception on brand authenticity. However, only 'consistent' and 'authoritative' have significant effects for luxury brands and are different from the general perception.

  • Objectives : We tried to establish standards for genuine by discriminating 3 kinds of pollen and spore herbs that are highly to be mixed with each other. Using an scanning electron microscope, we prepare a standard for discriminating external morphological characters of minute herbs, thereby contributing to the stable supply of genuine herbal medicines. Methods : Standard samples were confirmed by literature review on external morphological characteristics of original plants and herbal medicines, and collection and identification of original plants. The herbal medicines on the market were purchased and classified with using naked eye observation and magnifier. Finally, micromorphological identifications were conducted using an scanning electron microscope. Results : 1. Pini Pollen was clearly distinguished by its relatively medium size and a pollen grain with two swollen reticulate sacci at both ends. The verrucate ornamentation on the exine surface of the corpus and a sunken leptoma germ pore may be used as a discrimination criteria. 2. Typhae Pollen was distinguished by its relatively small size and a saccus on the end of a pollen grain. Reticulate ornamentation of exine surface of the corpus, and a slightly clear ulcerate germ pore can be used as a discrimination criteria. 3. Lygodii Spora was distinguished by its relatively large triangular-ovate shape and trichotomous fissure. Verrucate-tuberculate ornamentation of exine surface and trilete aperture could be used as a discrimination criteria. Conclusion : These results indicate that the use of electron microscopy is very effective for discriminating the external morphology of minute herbal medicines.

  • The trend of abstract expressions has become one of the fundamental causes of the problems relating to a sense of place in modern architecture. This trend began in earnest after the era of modernism, caused by the effect of modern dualism. Before analyzing the problems of the modern trend of abstract expressions and sense of place, a fundamental review of the establishment of human environments is necessary. In this context, this study deals with the principles of the establishment of an environment based on the logic of projection between human beings and milieu, through the concept of mediance by Augustin Berque, and based on this, causes of adverse effects on the establishment of environments in modernism were verified. In addition, the last section covers the conceptual supplements required in order for the concept of mediance to become practical, overcoming its limitation of being simply theoretical. Through this analysis on the concept of mediance, it is realized that a genuine sense of place can be achieved only when architecture moves beyond the individual dimension as a simply physical object, and instead plays a role as a socially sustainable community, embracing the people and unique objects therein.
