Social media is one of the important marketing channels for companies, changing the way interacting with customers. Marketers attract participation from customers' in social media platforms by producing branded content, which helps them gain various marketing results such as brand awareness, web traffic, and sales. The number of the empirical studies on the effects of social media on marketing performance is still low although various success stories and studies have been published. In particular, IT companies are trying to attract users onto their websites with social media content and promotions; however, they regard the number of the visitors as a vanity metric, which has little effectiveness. The study examined the Effect of the site introduced via Facebook, a typical social medium, on customers' revisit. Precedent studies proved that revisit, one of forms of major visit for satisfactory results of a website, is suitable for analyzing the operational output on Facebook pages. The results of the study demonstrated that Facebook content has a positive impact on website inflows and revisits. Also, it turns out that the higher the average website visit depth reinforces the positive relationship between the rate of the inflow and that of the site revisit.

In an effort to minimize operational expenses and supply users with more scalable services, distributed applications are actually going towards the Cloud. These applications, sent out over multiple environments and machines, are composed by inter-connecting independently developed services and components. The implementation of such programs on the Cloud is difficult and generally carried out either by hand or perhaps by composing personalized scripts. This is extremely error prone plus it has been found that misconfiguration may be the root of huge mistakes. We introduce AutoBot, a flexible platform for modeling, installing and (re)configuring complex distributed cloud-based applications which evolve dynamically in time. AutoBot includes three modules: A simple and new model describing the configuration properties and interdependencies of components; a dynamic protocol for the deployment and configuration ensuring appropriate resolution of these interdependencies; a runtime system that guarantee the proper configuration of the program on many virtual machines and, if necessary, the reconfiguration of the deployed system. This reduces the manual application deployment process that is monotonous and prone to errors. Some validation experiments were conducted on AutoBot in order to ensure that the proposed system works as expected. We also discuss the opportunity of reusing the platform in the transition of applications from Cloud to Fog computing.

Purpose: As the shared kitchen sector evolves into a new trend in the restaurant industry, not only operational support but also the physical environment for services is ranked as an important success factors. Therefore, the purpose of this thesis is to study the effect of shared kitchen service quality on experiential value, relational commitment, and long-term orientation. Research design, data, and methodology: In this study, a questionnaire was used to verify the structural relationship between shared kitchen service quality, experiential value, relational commitment, and long-term orientation for tenant companies in shared kitchen companies. The data were analyzed by using Partial Least Square-Structural Equation Modeling (PLS-SEM). Result: Facilities and support for the service quality of the shared kitchen had a positive (+) effect on the experiential value, and the environment did not. In addition, experiential value showed a significant positive (+) effect on relationship commitment and long-term orientation, and relationship commitment showed a significant positive (+) effect on long-term orientation. Conclusions: It was confirmed that the support quality among service quality affects the relationship formation. Thus, attention should be paid to activities to support stable business activities from the perspective of B2B services.

Background and objective: This study seeks to investigate domestic agro-healing farm resources so that preliminary data can be obtained on the systematic provisions for agro-healing programs in order to improve service quality and to identify the quality of agro-healing policy services. Methods: For this study, owners of agro-healing facilities were asked 24 questions via an online survey. An importance-performance analysis (IPA) was conducted to identify service quality for each policy sector. Results: Respondents' satisfaction levels were low when compared to agro-healing farm owners' perceptions of the above-average importance of each sector. The results from the resource analysis of domestic agro-healing farms indicated that the main operational purposes of farms were, in descending order, experience (90.0%), healing (86.7%), and education (84.0%). With respect to the type of program that was operated, cultivating crops (horticultural therapy) was identified most frequently at 83.3%. Conclusion: As a result of this study, the resources possessed by agro-healing farms were identified. In addition, the results of the IPA analysis in terms of service quality are not as good as expected, and performance levels should be increased to improve this. The results of this study are expected to provide useful information not only to improve the quality of agro-healing services, but also to revitalize the agro-healing industry while developing a systematic agro-healing program.

The inclusion of software and wireless communication devices in vehicles has raised concerns regarding automobile security. In its response, UNECE WP.29 implemented the first-ever international standard for automotive cyber security in June 2020. Yet, the existing disparity between national standards for automotive certification systems and 「UN Regulation No. 155」 has caused confusion among auto makers. This discrepancy not only jeopardizes the security of domestic vehicles but also poses challenges to the seamless import and export of automobiles. Hence, there is a need to enhance the automotive cyber security certification system; however, there is a dearth of scholarly discourse on this topic. Consequently, this study presents a proposal for enhancing the domestic automotive cyber security certification system. In view of this, existing legal frameworks such as the 「Motor Vehicle Management Act」 and the 「Self-Driving Vehicle Act」 were reviewed, along with domestic and international automotive certification systems. The recommendations for improvement, derived from the findings, encompass institutional, legal, and operational aspects. This study is highly significant as it examines both domestic and international automotive certification systems in an area where there is a lack of academic discussion.

본 연구는 모바일 시대의 진입, 글로벌 경쟁격화, 및 의료서비스 요구사항의 확대 등, 의료경영환경의 급격한 변화에 부응하기 위해 새로운 IT 기반 의료서비스가 필수적임에도 불구하고 이를 실현하고 있지 못한 중소형 규모 병원에 클라우드 기반 의료서비스를 제공할 수 있는 '중소형 병원의 클라우드 병원정보시스템(CHISSMH, Cloud Hospital Information System for Small Medium Hospitals)'의 아키텍처와 서비스 모델을 제시하였다. 스마트폰 시대에 진입하면서 개인단위의 클라우드 서비스는 일반화되었지만 비즈니스 단위의 서비스, 특히 병원정보시스템에 대한 클라우드 서비스의 도입은 초기단계이기에 이를 활성화하고자하는 차원에서 CHISSMH의 아키텍처를 개발하여 제시하였다. 특히 본 연구는 병원산업계에 클라우딩 서비스 도입 활성화를 위해 사용자관점이 아닌 서비스 제공자 관점에서 이에 대한 해결책을 제시하였다. 즉, 서비스 제공자가 고품질 및 합리적 가격의 클라우드 의료 서비스를 제공한다면 비록 일부 저해요인이 존재하더라도 도입이 활성화될 것으로 기대한다. 이를 위해 CHISSMH는 하드웨어뿐만 아니라 애플리케이션까지 가상화를 시도하여 자원공용화(Resource Pooling)를 추구함으로써 운영비용의 최소화를 통해 합리적 가격의 서비스를 제공할 수 있는 기술 기반 아키텍처와 서비스 모델을 제시하였다. 또한 CHISSMH이 15개 중소병원을 대상으로 서비스한 자료를 분석하여 CHISSMH의 합리성과 유용성을 제시하였으며, 전통적 소유형 HIS와 비교하여 44.5%의 IT 서비스 비용이 절감되는 것으로 나타났다.
