Ubiquitous interaction in a pervasive environment is the main attribute of smart spaces. Pervasive systems are weaving themselves in our daily life, making it possible to collect user information invisibly, in an unobtrusive manner by known and even unknown parties. Huge number of interactions between users and pervasive devices necessitate a comprehensive trust model which unifies different trust factors like context, recommendation, and history to calculate the trust level of each party precisely. Trusted computing enables effective solutions to verify the trustworthiness of computing platforms. In this paper, we elaborate Unified Trust Model (UTM) which calculates entity's trustworthiness based on history, recommendation, context and platform integrity measurement, and formally use these factors in trustworthiness calculation. We evaluate UTM behaviour by simulating in different scenario experiments using a Trust and Reputation Models Simulator for Wireless Sensor Networks. We show that UTM offers responsive behaviour and can be used effectively in the low interaction environments.

This research tested how the perceived risk and the trust affect the usage intention of the cloud computing. To this end, this research setups a research model and tests it with the statistic tools. In order to build the model, TAM (Technology Acceptance Model) and UTAUT (Unified Theory of Acceptance and Use of Technology) were employed and, the factors such as the perceived risk, the trust and the intention of the cloud computing use were derived. This research finds that the perceived risk does not affect the intention of usage. Also the perceived risk has the negative effect for the trust. Thus this research has the following suggestions.

Airlines are promoting self-service based technology by introducing mobile check-in, Kiosk and self-back drop systems, which will help customer satisfaction and efficiency. This study is about the usage intension to use Technology-based Airline Self-Service, the purpose of this study is to examine the key variables affecting Unified Theory of Acceptance (UTAUT2) in using Technology-based Airline Self-Service. According to the results of the ANOVA, there was a significant difference among the groups according to the experience of the self-service device. And analysis results using Structural Equation Model(SEM) was suggested that the performance expectation and hedonic motive of UTAUT2 model were found to have significant influence on initial trust. Also, initial trust affects the intention to use. There are some moderating effects on the structural equation by groups according to the experience of the self-service device. This research has significance in that it can help establish a marketing strategy of airlines to expand the self-service based on the airline technology.

Recently, following the development of FinTech technology that combines finance and information and communication technology, the need and social demands for a block chain technology-based trading system have increased significantly. In this study, a research model was developed and hypothesized through literature research on the concept of block chain technology, the technology acceptance model, and the unified theory of acceptance and use of technology. The research theories were tested by collecting data through surveys and analyzing the collected data. This study conducted empirical research to identify the factors influencing the user acceptance intention and utilization behavior of the block chain technology in introducing the block chain technology. First, factors affecting the acceptance intention of the blockchain user were performance expectation, effort expectation, social impact, and blockchain transparency variables. Second, the facilitation conditions and stakeholder confidence variables were analyzed as factors that did not affect the acceptability of the blockchain users. Third, variables such as blockchain transparency, stakeholder trust and intention of acceptance are factors that affect the usage behavior of the blockchain. Fourth, it was confirmed that the acceptance intention had a very high explanatory power on usage behavior of Blockchain technology.

Wearable Technology is going to be the biggest buzzword and the next generation of digital revolution in the near future. Wearables have changed the focus of the healthcare industry to prevention programs in order to encourage individuals to be more active and to take the responsibility of their own health. Although, the intention of consumers to use wellness wearables has been growing rapidly, the number of individuals who refuses continued use of such devices increases day-by-day. Diffusion and innovation of new technology could be more efficiently gained by consumer's adoption. So, it is extremely important for providers and designers to understand the impact of positive and negative factors on consumers' intention to use wellness wearables. Moreover, a unified framework is required for better understanding of individuals' behavioral intention for using wellness wearables. Thus, the goal of this study is to identify the potential factors that influence consumers' willingness to use wellness wearables as well as proposing a unified framework based on Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and Value-based Adoption Model (VAM) with two extra factors, perceived trust and perceived health increase. The findings of this article improves the theoretical understanding of the engaged factors in the proposed research model of the study.

The aim of the study was to examine the effect of trust, awareness, attitude, subjective norms, and behavioural control on intention and examine the mediating role of trust in the relationship between awareness and attitude. The population was Muslims in Bali Province, with a sample of 150 respondents. Quantitative analysis is used based on multivariate analysis using the SEM model with a variance-based PLS. The results are as follows: (1) knowledge has a significant positive effect on attitude. (2) Awareness has no significant effect on attitude. (3) Awareness has a significant positive effect on trust. (4) Trust has a significant positive effect on attitude. (5) Attitude has no significant effect on intention. (6) Subjective norm has a significant positive effect on intention. (7) Behaviour control has a significant positive effect on intention. (8) The role of trust is a conscious mediation that impacts attitude. The study provides insight into Islamic bank managers to meet prospective customers' expectations and identify their intention to become customers through managing trust, awareness, attitude, subjective norms, behavioural control, and intention in one unified whole as internal resource. This study enriches empirical evidence on the Theory of Planned Behaviour, which examines knowledge, awareness, and belief.

신기술의 수용에 영향을 미치는 요인에 관한 연구들이 다양하게 이루어져 오고 있다. 특히 4차 산업혁명의 도래와 더불어 등장한 새로운 기술을 고객들이 수용함에 있어서 영향을 미치는 요인과 이 요인의 영향력에 대한 다양한 연구들이 지속적으로 이루어지고 있다. 이론적인 모형으로는 기술수용모형(TAM) 혹은 확장된 통합기술 수용모형(UTAUT2)에 기반한 연구들이 주류를 이루고 있다. 하지만 이들 모형에는 신뢰성(trust) 변수가 없다. 이에 본 연구에서는 신뢰성을 추가하여 증강 현실(AR)을 대상으로 검정을 하였다. 신뢰성을 독립 변수로 본 경우, 매개 변수로 본 경우, 조절 변수로 본 경우 3가지를 통계적으로 분석하였다. 그 결과 신뢰성은 독립 변수들과 사용 의도(수용 의도)간 매개 변수로 보는 것이 가장 설명력이 높았다. 본 연구는 이론적인 측면에서는 신뢰성은 매개 효과로서의 역할을 하다는 점을 밝혔다. 실무적인 측면에서는 새로운 기술 수용에 있어서 신뢰성이 무엇보다 중요하므로 신뢰성 확보에 우선 순위를 두어야한다는 것이다.
