The purpose of this study is to analyze the effect of characteristics of the online shopping mall website and the service quality factors required on the online service on the reliability and repurchase intention. Through this, the key customer response service and operation management strategy can be proposed for the growth of kidult online shopping mall which is continuously spreading. Also, implications for development direction can be suggested. For this purpose, the ES-QUAL and E-Rec-S-QUAL factors proposed by Parasuraman et al.(2005) were set as independent variables, as well as professionalism, diversity, playfulness, and personalization, and website reliability as a mediating factor, and repurchase intention as a dependent variable. For the analysis, a structured questionnaires survey was conducted to 200 domestic online shopping mall users. The main results are as follows. First, the professionalism, personalization in the characteristics, and service quality factors had positive effects on website reliability. Second, playfulness, personalization in the characteristics, and service quality factors had positive effects on repurchase intention. Third, website reliability had a positive effect on repurchase intention. Fourth, website reliability was found to mediate the relationship between predictive (independent) variables and dependent variables. The above results show that if a professional online shopping mall is equipped with online service quality and establish personalization through enhancing the professionalism, the online shopping mall can form a website reliability and expect to build continuous relationship with customers. In addition, implications can be suggested for future customer response service and operation management strategies.

Although the study of IT services has increased in recent years, few study have focused on trust based recovery process. Additionally, users of IT services have different use purpose depending on service type. Therefore, the purposes of this research is to propose trust recovery model of smartphone applications and to examine the moderating effect of service type on the use of smartphone applications. To achieve research purposes, we suggested service failure type using the scenario technique and empirically verified by conducting survey. The results showed that the procedural justice and interpersonal justice have influence on trust and trust had an effect on the all quality factors (system, information, service quality). Also, information quality and service quality had an effect on the customer loyalty. Finally, service type had significant moderating effects on the relationship between perceived justice and quality.

IT service is becoming a critical business operation in the age of information revolution. In providing IT services internally to other functions of the corporation and externally to other organizations, sharing of knowledge between business people and system people is known to become more and more critical for successful IT services. Purpose of this research is to examine the impact of IT service quality on knowledge sharing activities between IT service providers and users. Theoretical research model, through an extant literature review, is proposed here, consisting of IT service quality, relationship quality(satisfaction, trust and commitment), and the level of knowledge sharing activities. Survey results of 183 users indicates that IT service quality significantly influences commitment through satisfaction and trust, which in turn influences the level of knowledge sharing activities. Also, interestingly, satisfaction and trust do not directly influences the level of knowledge sharing,but indirectly, through commitment.

최근 컴퓨터 기술의 발전과 네트워크의 개방화 그리고 무선 모바일 통신 기술의 비약적인 보급으로 인하여 컴퓨팅 환경을 이루고 있는 각종 장치(PC, 모바일 단말, 저장장치, 네트워크 기기 등)가 다양한 형태의 보안 위협에 노출되어 데이터의 유실, 조작, 유출되어 금전적인 피해를 입거나 프라이버시 침해를 받고 있다. 이러한 문제를 근본적으로 해소하기 위하여 설립된 TCG(Trusted Computing Group)는 세계적인 IT 핵심기업들을 중심으로 구성된 비영리 단체로서 PC 혹은 모바일 기기 등의 단말과 서버 장비 그리고 저장 장치 및 네트워크로 구성된 컴퓨팅 환경에서 보안성 향상 및 데이터의 신뢰성을 제고하기 위하여 TPM(Trusted Platform Module)이라는 반도체 칩을 신뢰의 기반(root of trust)으로 한 신뢰 플랫폼을 제안하고 있다. 한편 SaaS(Software as a Service)는 패키지 형태의 소프트웨어를 네트워크 서비스 형태로 바꾸어 사용량에 비례한 요금제로 과금하는 방식을 채택하고 사용자가 온디맨드로 요청한 서비스를 적시에 제공하는 기술로 최근 전세계적으로 각광을 받고 있다. 이때 다양한 컴퓨팅 환경 안의 사용자에게 높은 신뢰성과 보안성 그리고 연속성을 갖는 SaaS 서비스를 제공하고 데이터의 무결성 및 비밀유지와 정확한 서비스 사용시간을 기록하고 업로드하는 기능들을 제공하는 SaaS 플랫폼은 TPM기반의 신뢰컴퓨팅 기술을 통하여 쉽게 구현될 수 있다. 본 논문에서는 일시적으로 네트워크와 차단된 상태의 PC 혹은 모바일 단말에서도 위의 조건들을 만족하는 SaaS 서비스를 지원하는 신뢰 플랫폼이 가져야 할 기능들에 대하여 분석-도출한 후 그러한 기능들을 제공하는 컴포넌트로 구성된 신뢰형 SaaS 사용자 플랫폼을 설계하였다.

Due to COVID 19, we are facing unprecedented phenomena. Among various industries, the aviation industry, as it is directly affected by the corona crisis is actively establishing various survival strategies, such as expanding cargo transportation. The market size of air cargo transportation is continuously increasing due to the characteristics that distinguish it from other transportation, and as individualism and selfishness deepen in the aftermath of COVID 19, it can be inferred that the concept of reciprocity within distribution channels will become important in the post-corona era. The specific contents of this study(research question) are as follows. First, as a central member of the air logistics distribution channel, logistics service companies business process and the sub-dimensions of trust of are identified, and how trust is built with transportation companies is investigated. Second, the effect of such trust on the various performances of logistics service companies is analyzed. Third, we examine whether the influences of the sub-dimensions of trust change according to the perceived reciprocity of logistics service companies. In addition, we investigate whether the perceived reciprocity changed before and after the corona situation. In particular, this study theoretically integrates the concepts of trust and commitment, which have been distinguished in many prior studies, to improve the parsimony and practicality of the research model. This study will be able to present useful academic and practical implications by empirically examining how trust is built between members of the air logistics distribution channel and furthermore, how much it affects the performance of logistics service companies, and by identifying the moderating effect of reciprocity.

This article deals with a problem of setting reliability targets of the railroad systems where the punctuality target is given to the operator and a penalty is imposed for the year when the target is not met. The operator should set the reliability targets of the railroad system and sub-systems because the reliability affects the expected number of years when the penalty is imposed. This paper presents a procedure for setting the service reliability target and equations to calculate the expected number of years when the penalty is imposed and the probability that the operator should pay the penalty per year according to the mean kilometer between service failures of the railroad system and sub-systems.

인터넷 보급의 확산 및 네트웍 성능의 향상으로 멀티캐스트 기술을 응용한 서비스가 일대다의 정보 전달 서비스 위주에서 다중 사용자 네트웍 게임 (MUG) 등과 같이 인터넷을 사용한 다자간 상호작용 서비스로 그 응용 서비스 범위를 넓혀가게 되었다. 본 논문에서는 이러한 다자간 상호작용을 지원하기 위한 다대다 멀티캐스트 세션을 위한 신뢰성 있는 멀티 캐스트 프로토콜에서 발생하는 비용을 기술하고, 기존의 일대다 멀티캐스트 세션을 위해 제안된 신뢰성 있는 멀티캐스트 프로토콜들(RMTP, TMTP)과 다대다 멀티캐스트 세션을 위해 제안된 프로토콜들(SRM, Lorax. GAM)에 대 한 시뮬레이션을 통하여 에러 복구 기법의 처리비용을 측정함으로써 다대다 멀티캐스트 세션에 적합한 신뢰성 있는 멀티캐스트프로토콜을 제안한다.

코로나19로 인하여 우리는 이제껏 경험하지 못했던 현상들을 마주하고 있다. 여러 산업 중에서도 항공업계는 코로나사태의 직접적인 영향을 받음에 따라 화물운송 확대와 같은 다양한 생존전략을 적극적으로 수립하고 있다. 항공화물운송은 타 운송과 구분되는 특성으로 인하여 시장규모가 지속적으로 증가하고 있으나 코로나19 여파로 개인주의·이기주의가 심화됨에 따라 포스트 코로나 시대에는 유통채널 내에서 호혜 개념이 중요하게 고려될 것으로 추론할 수 있다. 이런 상황에서 항공물류 서비스기업은 어떻게 항공사와 신뢰를 구축하고 관계를 맺어야 바람직한 성과를 거둘 수 있을까? 바로 이것이 본 연구를 추진하게 된 배경이다. 본 연구는 항공물류 유통채널 구성원 간의 신뢰가 어떻게 구축되는지, 나아가 물류서비스기업의 경영성과에 얼마나 영향을 미치는지를 실증적으로 살펴보고, 호혜의 조절효과를 규명함으로써 학문적으로나 실무적으로 유용한 시사점을 제시할 수 있을 것이다.
