본 논문에서는 사물인터넷 서비스와 블록체인 플랫폼간의 연동을 위한 아키텍처를 제안한다. 블록체인은 다양한 산업분야에서 데이터 신뢰성 및 안전성 측면에서의 효율성을 제공한다. 반면에 데이터 쓰기 및 읽기에 대한 낮은 성능 때문에 실제 서비스 적용하기 어렵다. 특히 사물인터넷 서비스와 같은 다량의 데이터가 발생하는 분야에서는 블록체인을 실질적으로 적용하기 어렵지만, 사물인터넷은 프라이버시 및 데이터 보안 측면에서 많은 보안 문제를 야기할 수 있는 분야로써, 블록체인을 통한 데이터 추적 및 신뢰성 보안을 필수적으로 요구된다. 본 논문에서는 이와 같이 실시간성과 신뢰성을 보장하기 위한 사물인터넷 연동형 블록체인 플랫폼 아키텍처를 소개한다. 실시간성을 유지하기 위해서 단일 피어 검증을 통한 실시간 데이터 관리를 활용하며, 신뢰성 유지를 위해서 합의를 통한 분산원장을 활용한다. 단일 피어 검증 데이터는 합의 과정을 거치기 이전에 데이터를 수신받은 단일피어가 분산원장과 별도의 상태 데이터베이스를 통해 실시간 데이터를 저장하여 실시간 서비스에 제공한다.

본 연구에서는 서비스산업종사원들의 조직공정성이 이직의도에 어떤 영향을 미치는지를 분석하였다. 또한 조직공정성과 이직의도에서 조직신뢰의 매개역할을 알아보고자 한다. 서비스산업 종사원들의 직무 및 역할과 이직의도와 관련한 연구들을 살펴보면 서비스산업 종사원들은 보다 나은 업무결과를 위하여, 업무 스트레스를 경험하게 되고 이 업무 스트레스는 이직의도를 높게 하는 변수로 작용하게 된다. 따라서 본 연구에서는 서비스산업 종사원들의 조직공정성이 이직의도에 어떤 영향관계에 있는지를 실증적으로 분석해보고 그 영향관계에서 조직신뢰는 어떤 매개역할을 하는지를 알아보고자 한다.

This study examined relationship of effect between the characteristics of specialized portal and two branch dimension(cognitive and emotional e-trust) of e-trust on the specialized portal web-site. The characteristics of specialized portal web-site composed the guarantee factor, the structural factor, information factor, the entertainment factor and the flow factor by prior research. The model of e-trust strategy for specialized portal web-site is tested here using data from 122 samples. Result of factor and regression analysis show that the hypothesized relationships are significant. In examining the relationships of the factors in the study, the guarantee, structural and information fact effect on building of cognitive e-Trust. Second, the entertainment and flow factor effect on emotional e- Trust. Third, the cognitive and emotional e- Trust effect on the satisfaction of e-Service users. As these results, this study found out difference paths of e-Trust which effect on the satisfaction of e-Service by cognitive and emotional e- Trust approaches to the specialized portal web - sites.

본 연구는 서비스업에서 서비스 품질을 측정하는 것에 있어서 표준과 기대치에 관한 비교다. 외식산업에서의 기대의 개념은 서비스 품질을 측정한다는 것으로 이를 표준화하기 위해 광범위하게 사용되었다. 그러나, 서비스 품질 측정에 있어서 기대치가 당위성과 신뢰성에 의해 많은 연구자들에 의해 비평되었다. 이 연구의 목적은 기대치에 통한 서비스업에서의 서비스 품질을 측정한다는 것이다. 본 연구는 다음과 같은 한계점을 가진다. 첫째로, 연구의 표본수가 적기 때문에 분석에 있어서 신뢰성이 떨어졌다. 둘째, 한정된 한국의 호텔을 이용했던 여행자에 한하여 설문을 했기 때문에 객관성이 결여될 수가 있다. 셋째, 총체적인 서비스 품질과 고객 만족의 측정은 하나의 항목 저울과 이와 같이 그것을 사용하면서 수행되었기 때문에 이들의 신뢰성을 추정하는 것이 불가능했다. 연구결과 소비자가 서비스의 평가를 위한 비교 기준으로서 기대치에 대한 4개의 다른 수준을 가진 요인을 사용하였다. 본 연구에 있어서 기대의 개념이 고객 만족에 서비스 품질보다 관계가 높다는 것을 밝힌다.

Current CORBA has been suggested a solution for complexity of software in distributed environment. But it can't provide reliability about data transfer. For instance, CORBA can't provide object to client when the network are unstable or congested. In an existing CORBA, client has to wait when there is congestion between client and object implementation while client get a service from object implementation. So In this paper, we propose Fault-Tolerant CORBA Service (FTS) which has an intelligent redirection about an object that client requests. Moreover, we designed and implemented Fault-Tolerant Service to provide reliability by extending existing CORBA ORB. Therefore it provides reliable connection throughout the proposed Fault-Tolerant Service.

This study aims to examine effects of service authenticity and service quality on the customer satisfaction and customer loyalty in mediation of customer trust in financial investment company. This research model was validated by the statistical tool of SPSS18.0 and AMOS18.0 using survey data collected from the experienced of financial investment company. The results of this study are summarized as follows. First, service process authenticity has a significant effect with customer satisfaction and customer oriented authenticity has a significant effect with customer satisfaction in mediation of customer trust. Second, service quality(tangibility, reliability, assurance, empathy, except responsiveness) has a positive effect(empathy is the highest of all) with customer satisfaction and the importance of service authenticity and service quality can be confirmed from customer satisfaction and customer loyalty. Third, customer satisfaction and customer loyalty as well as trust and satisfaction have significant effects between them, but there have no significance between trust and loyalty. Finally, this study suggests directions of marketing strategy through build up trust in a strong relationship with the existing loyal customer in financial investment company.

Collaboration works on R&D project have many characteristics in interoranizational relationships. There are many variables on explaining the their relationships. In the previous study, I chose some relevant variables and some hypotheses. Base on service marketing theories and relationship marketing perspective I suggest 5 hypotheses. Independent variables are fairness and quality, and dependent variable is loyalty. And trust are treated as the intervening variable between the independent variables and dependent variable. To test the research model and some hypothesis empirically, I collected the data using the questionnaire. Sample size was 448, it was enough to analyze statistically. Data were analysed using the SPSS and AMOS. In the previous study, H1($fairness{\rightarrow}trust$), H2($quality{\rightarrow}trust$), H5($trust{\rightarrow}loyalty$) were accepted, but H3 and H4 were rejected. The reason H3($fairness{\rightarrow}loyalty$) and H4($quality{\rightarrow}loyalty$) were not accepted might be attributed to the fact that trust was the mediating variable between fairness and loyalty, quality and loyalty. Specific research methodologies and statistical findings from AMOS were referred in the previous study(Jeong 2018). In this study, I suggested some hypotheses on the mediating role trust between fairness and loyalty and service quality and loyalty. Using the PROCESS-macro, I found that trust was the mediating variable between fairness and loyalty as well as service quality and loyalty. This research is the complementary and extended study from previous research.

The purpose of this study is to analyze the structural relationship between politicians' YouTube information service quality, politician's image and trust, and voters' social and political participation intentions. To investigate this, 306 voters were sampled through an online survey. The quality factors of the politician's YouTube information service were found to have a positive effect on the image of a politician. Among them, timeliness and reliability had a positive effect on the trust of politicians, but playfulness did not. Both the image and trust of politicians through YouTube were found to have a positive effect on voters' intention to participate in society and politics. As a result of examining the indirect effect, it was found that the image of a politician had an indirect effect on the quality of information service and the intention to participate in society and politics. This study is significant in revealing that the fact that the image and trust of politicians is a major variable that appeals to citizens' social and political participation is also applicable to YouTube.
