With the recent development of manufacturing technology and the diversification of consumer needs, not only the process and quality control of production have become more complicated but also the kinds of information that manufacturing facilities provide the user about process have been diversified. Therefore the importance of big data analysis also has been raised. However, most small and medium enterprises (SMEs) lack the systematic infrastructure of big data management and analysis. In particular, due to the nature of domestic manufacturing companies that rely on foreign manufacturers for most of their manufacturing facilities, the need for their own data analysis and manufacturing support applications is increasing and research has been conducted in Korea. This study proposes integrated analysis platform for process and quality analysis, considering manufacturing big data database (DB) and data characteristics. The platform is implemented in two versions, Web and C/S, to enhance accessibility which perform template based quality analysis and real-time monitoring. The user can upload data from their local PC or DB and run analysis by combining single analysis module in template in a way they want since the platform is not optimized for a particular manufacturing process. Also Java and R are used as the development language for ease of system supplementation. It is expected that the platform will be available at a low price and evolve the ability of quality analysis in SMEs.

In the context of social platform, this study clarifies the concept of customer value, the role of knowledge sharing, and the relationships between knowledge sharing and customer value. The study builds a theoretical model regarding social platforms and customer value that offers implications for advertising & PR practitioners.

Introduction In order to solve the information asymmetry and make full use of resources (unused goods, spare capacity and so on), the sharing economy, which based on the application of mobile internet technology and focused on the consumption of the right to use, is developing rapidly. Lack of trust is considered to be one of the important problems hindering the development of sharing economy. Möhlmann (2015) said that trust is a fundamental determinant of sharing economy development and ensuring shared satisfaction. At present, sharing economy enterprises have established product evaluation system and docked a third party credit rating system (i.e. Zhima Credit) to promote consumers’ trust. However, with most enterprises are becoming more and more consistent in evaluation and credit rating system, there is a new problem emerged: how to further deepen consumers’ trust in order to promote consumers’ intention to participate continuously (Zucker, 1986; Lewis & Weigert, 1985). Granovetter (1985) mentioned that trust is the product of social relationships. Botsman and Rogers (2011) made it clear that social networks play an important role in building trust in sharing economy. And people are always more willing to accept the opinions of people who have social relations with them (Lu, Zhao, & Wang, 2010). Hence, with the feature of participant of everyone in sharing economy, it is necessary to further strengthen consumers’ trust through the social interaction among consumers and between consumers and sharing platforms. Theoretical Development Sharing economy is based on LBS and other new technologies to realize the matching of supply and demand information across time and space. And to a certain extent, it solves the problem of information asymmetry in the era of e-commerce. Yet consumer have new requirements for product information. For example, consumers are more concerned about whether the utility of products and services can meet their needs (i.e. some consumers are more concerned about when to reach their destination than the performance of the car). But it is difficult for company to understand each everyone of consumers’ utility preference and publish product utility information based on these preferences (Xie & Gerstner, 2007). Because this kind of utility preference has the characteristic of timeliness and personalization. Therefore, consumers’ perceived uncertainty about the utility of the product will also affect the consumers’ trust. In summary, we then address these research questions:(1) can the promotion of trust between consumers and sharing platforms be achieved through the socializing of sharing platforms and then affect consumers’ intention to participate continuously; (2) if so, which type of privacy protection method and social information can promote consumer trust; and (3) does the impact of sharing platform socialization on consumer trust vary according to consumers’ concerns about the perceived utility uncertainty of the product. Research Design We then address these issues using experiment data. The first experiment was a 2 (social media: have, not have) x 2 (individual trust propensity: trust, not trust) between-subject design on the intention to trust sharing platform and participant continuously. Perceived utility uncertainty was added to this design as a moderator. Moreover, the second experiment was a 2 (social information type: hedonic, utilitarian) x 2 (degree of privacy protection: week, strong) between-subject design on the intention to trust sharing platform. Our scales come from existing scales and optimize it according to the characteristics of sharing economy (Schneider, 1999; Dhar & Wertenbroch, 2000; McKnight, Choudhury, & Kacmar, 2002). Results and Conclusion The results of the first experiment show that whether or not the social platform has no significant impact on the consumer trust if the individual tends to trust others. And for individuals who tends to do not trust others, they are more likely to trust socialized sharing platforms. The higher the consumer perceived utility uncertainty is, the higher (lower) trust of the consumer platform in the socialized (not socialized) sharing platform. For the second experiment results, in the context of sharing economy, the utilitarian information has a greater positive impact on the consumer trust than the hedonic information. In addition, the stronger the privacy protection of sharing platforms, the higher the trust of consumes. This study makes several academic contributions. First, we extend the topic of socialization to sharing economy context. Second, we add the perceived utility uncertainty as a moderator, and supplement the role of perceived uncertainty. This research also provides several practical implications. First, sharing platform can promote their consumers’ trust by establishing their own social platform. This platform can be used as a differentiated competitive strategy for sharing platform. Second, sharing platform should guide consumers to share utilitarian information (i.e. weather for specific place or real time traffic) to improve consumer satisfaction. Third, sharing platform can access consumer preference information through this social platform for further product development and classification.

The number of individuals using peer-to-peer and access-based services through collaborative consumption platforms (CCP) has been grown dramatically for a few reasons. CCP makes consumers convenient because it enables individuals trade directly without contacting each other. Thus, CCP, a digital platform, encourages more consumers to use access-based. CCP is temporal access-based service to a good. A good is usually accessed and traded in the absence of a service provider representative through CCP, and thus, misbehavior can occur and then be diffused into other consumers. Most of CCPs are based on digital platform, which provides participants with space where they can trade. Because the interactions in CCP is usually non-face to face communication and the participants tend to have similar interests and chat with task-oriented and low socio-emotional content, they can feel submerged in a crowd and indistinguishable from others. That is, participants feel like the sense of deindividuation which means to lose all sense of individuality. When participants face misbehavior of multiple previous customers, such deindividuation makes them conform social norm that they think that others do misbehavior as well. Based on social identity theory and deindividuation, this research examines the mediating effect of deindividuation on the relationship between previous misbehavior and misbehavior and the moderating effect of the self-disclosure on the relationship between previous misbehavior and deindividuation.

Since more and more consumers rely on online consumer reviews in their purchase decision making, we have observed the emergence of empirical studies on online reviews in different contexts. Such studies look at various dimensions surrounding online reviews; nevertheless, none of them actually gives a more comprehensive picture as to the rating differences across online rating platforms and/or across time, let alone explains such differences. This study aims to address these understudied but managerially relevant issues. In our empirical study, we focus on hotel ratings across platforms and across time (i.e., across identified change point in time), and explain such differences by review text associating with the ratings. We investigated San Francisco hotels that were rated on both Tripadvisor and Expedia, and utilized the General Inquirer dictionary to identify the categories of words in a review. Regressions analyses were then conducted for the explanation of rating differences. We found that rating differences, in both the cross-platform and the longitudinal cases, are substantially associated with the number of words (in a negative relationship). Furthermore, word tags identified from the review text associated with ratings also explain the rating differences. To conclude, the research reveals that for a specific service provider, online ratings may vary significantly in both the cross-platform and the longitudinal senses. It demonstrates that adopting a systematic approach and utilizing an established semantic dictionary, information extracted from review text can substantially explain such differences.

RNA interference (RNAi) has been considered as an alternative strategy to control agricultural pest whereby double-stranded RNA triggers a potent and specific inhibition of its homologous mRNA. Since small dsRNAs are required for various RNAi applications, there is a need for cost-effective methods for producing large quantities of high-quality dsRNA. In this study, Bacillus thuringiensis (Bt) based dsRNA production platform was established under control of sporulation-dependent promoter and vp1 gene of Sacbrood virus (SBV) was introduced. The dsRNA against vp1 gene produced from the Bt suppressed the replication of SBV. In addition, the dsRNA was assembled into inulin coated-nanoparticle to increase stability of dsRNA in environment.

The virus-like particle (VLP) is similar to a pathogenic virus and has a high immunogenicity. However, in the selection of various structural proteins to form VLP, all expression systems commonly consume most of the time and suffer from various difficulties. Therefore, there is a need for a system that can rapidly determine the structural proteins required for effective VLP production. This study aims to construct a transient expression platform using insect cells to solve this problem. Plasmid-based expression vectors and baculovirus-inducible expression vectors were constructed. The vectors were evaluated for overexpression using EGFP. We also confirmed the formation of virus like particles through overexpression of virus structural proteins.

More people travel oversea as the economic size of Korea is getting larger and more new jobs are requested to be created by the society. To respond to these trend and request, Incheon International Airport Corporation (IIAC) is about to expand its processing capability with a new terminal; 54 million passengers to 72 million. IIAC is also introducing new strategies such as open innovation (OI) and creating shared value (CSV). With these changes, IIAC faces new challenges of restructuring its business and organization with new ideas. Most organizations including IIAC are becoming more dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the OI paradigm which is reported as a convincing strategy to improve competitiveness in terms of budget and time-to-market. OI is to quickly react to the rapidly changing business environment and is adopted to support startup incubation. In the previous research with IIAC, three major tasks were defined; utilizing the IIAC brand power for external vendors, building a technology road-map, and introducing a collaboration support system. This paper deals with the collaboration system as proposed in the previous research. We focused on the collaboration process for startup incubation. Cases were studied; the K-startup model by the government, a university model to explore youth startups, and a R&D institute model to study professional startups. Based on the case studies, we defined an IIAC model and proposed issues to take care of. The model is distinguished from the other studied models since IIAC is a prospective customer of new technology.

Compared to the early 2000s, the number of tourists in Korea has increased significantly. Approximately 40 million tourists visit Korea each year. In line with this trend, various technologies for developing tourism content have reached a very high level. Therefore, adding experience-oriented AR (Augmented Reality) game based on LBS (Location-Based System) to existing tourist contents will create a new tourism content platform that can give new experience to tourists . This paper proposes a tourism contents platform based on Suwon Hwaseong Fortress which can give such a new experience.

본 연구는 온라인 큐레이션 플랫폼을 이용한 외현적 정보의 제공이 현대미술에 대한 일반대중의 진입장벽을 낮추는 효과를 가지는지 알아보았다. 현대미술은 일반대중이 접근하기 난해한 장르로 여겨져 왔다. 한편, 미술 감상에 대한 연구들은 외현적인 정보의 제공이 미학적 감상 경험에 긍정적인 영향을 줄 수 있음을 밝혔다. 따라서 본 연구에서는 작품에 대한 구체적 정보를 제공하는 것이 현대미술을 감상하는 데에 긍정적인 영향을 미칠 수 있는지 알아보았으며 감상 경험을 심리학적으로 분석한 Leder et al.(2004)의 이론적 모델에 기초하여 외현적 정보가 어떠한 인지적 처리과정을 도와주는지 분석하였다. 더 나아가 최근의 전시 트렌드를 반영하여 온라인 플랫폼 환경을 적용하였다. 실험 1에서는 작품과 설명문이 제공되었고 작품에 대한 이해도, 관람의향을 보고하였다. 실험 결과, 해설이 제시된 조건에서 작품에 대한 이해도가 더 높았다. 또한, 긴 해설이 제시된 조건에서 해설 이해도와 관람의향을 작품이해도가 완전매개하는 매개모형이 나타났다. 실험 2에서는 ARS 설문을 추가하고 온라인 큐레이션의 능동적인 조작 환경을 재현했다. 실험결과, 해설이 제공된 조건들에서 관람의향, 작품이해도가 더 높았다. 예술사적 의미, 자아성찰, 창의성 등 Leder et al.(2004) 모델의 후기 단계에 해당하는 지표들 역시 해설조건에서 더 높은 것으로 나타났다. 종합하면, 온라인 큐레이션 환경에서의 정보전달이 일반대중의 현대미술 작품에 대한 인지적 처리와 판단에 도움을 줄 수 있었다.

ABSTRACT The growth of the social platform has led to a rapid increase in sustainable value cocreation activities with customers in order to know what a customer wants. In this study, we have studied about co-creation experience in social platform service. Previous prior studies have systematically classify co-creation between customer and enterprise as co-product and value-in-use, Conceptual factors. The co-creation and value-in-use factors theoretically derived from previous researches attempt to investigate the relationship between value co-creation experience and online service quality. We also tried to investigate the relationship between value co-creation experience and online service quality, customer equity, and online word of mouth. To do this, social platform services are divided into open sns and closed sns. Open SNS was targeted to Facebook, Twitter, and Pintrest users. Closed sns were targeted to Instagram, Cyworld, Band, and KakaoTalk users. In this study, it was confirmed that the relationship between online service quality, customer equity, and online word of mouth is significant through value co - creation experience. In the future, companies that design social platforms will be asked to do what they should do to co-create with customers, and provide suggestions for how to operate the platform in order to continuously activate value co-creative experiences.
