In the wake of Fishbein and Ajzen's the Theory of Reasoned Action (TRA), Davis (1989) proposed a Technology Acceptance Model (TAM) to account for how perceived ease of use, perceived usefulness, and attitude predict behavioral intention to use Information Systems (IS). However, TAM is incomplete in one important respect: it does not account for social influence In the acceptance and utilization of new information systems. This study investigated the relationships between organizational tasks and intention to use internet using TAM. For using internet, social network is an important factor because the natural characteristic of internet is community-based. The results showed that Organizational Culture (OC) plays an important role in explaining intention to use the internet. Using O'Reilly et al. 's measurements, we extended and empirically validated the proposed model using Structured Equation Modeling (SEM). These findings enable future researchers and practitioners to apply the OC variable in the various contextual domains.

A double sampling procedure with zero acceptance number for the first sample whose operating characteristic closely matches that of a given single sampling plan and whose combined sample size does not exceed that of the given single sampling plan is proposed. The proposed double sampling plans corresponding to the MIL-STD-105D plans are tabulated and it is found that their ASN's are considerably smaller than those of corresponding MIL-STD-105D single or double sampling plans.

Recently, various mobile services are provided by the spread of wireless network infrastructures and smart devices. The improvement of cloud computing technologies increases the interests for enterprise mobile cloud services in various IT companies as well. By increasing the interests for enterprise mobile cloud services, it is necessary to evaluate the use of enterprise mobile cloud services. Therefore, the factors which affect the user acceptance of enterprise mobile cloud services are analyzed on the basis of Davis' technology acceptance model in this research. As analysis results, four external variables have significant effects on perceived ease of use of mobile cloud services. Also, these variables indirectly affect attitude toward using cloud services. The results show that the security is the most important factor for attitude toward using enterprise mobile cloud services. The service users also consider the interoperability as an important factor for the user acceptance of cloud services. The perceived ease of use has more contribution than the perceive usefulness on attitude toward using enterprise mobile cloud services. This research has both industrial and academic contributions because it provides the guideline to companies for introducing the enterprise mobile cloud services and apply the technology acceptance model on new IT services.

In this study, we explored Technology Acceptance Model(TAM) to introduce Blockchain technology in the medical field. It extracted five external variables(Security, Availability, Reliability, Diversity, Economic feasibility) through previous studies. It set the study model for a path to acceptance intention through the information reliance of recognized easiness and recognized usefulness. As results of empirical analysis, H1-1(Security →Perceived Easiness) was rejected. H1-2(Availability→Perceived Easiness), H1-3(Reliabilit→Perceived Easiness), H1-4(Diversity →Perceived Easiness), H1-5(Economic →Perceived Easiness) were adopted. Hypothesis 2 was a relations between Blockchain's characteristics and Perceived usefulness, all the Hypothesis were adopted. Hypothesis 3 and Hypothesis 4 indicated that H3-1(Perceived Easiness →Perceived usefulness) was rejected but H3-2(Perceived Easiness → information reliability), H3-3(Perceived usefulness → information reliability), and H4(information reliability→acceptance intention) were all adopted. It was confirmed that it is important to emphasize the importance of stability to introduce block chain technology to medical centers, but it was necessary to use a design that can increase the easiness from the prospect of users.

The purpose of this study is to derive factors that affect the acceptance of digital transformation in ports and empirically analyze the impact of these factors on the acceptance of digital transformation through a survey of port workers. Additionally, we test whether acceptance attitude plays a mediating role in the relationship between these factors and digital transformation acceptance. The variables used in this study are as follows. First, knowledge, self-efficacy, and involvement were included as variables related to individual characteristics, relative advantages, complexity, observability were included as variables related to innovation characteristics, and government regulations and competitor pressure were included as variables relate to environmental characteristics, so that a total of eight latent variables were selected. The results of this study are summarized as follows. First, two variables among individual characteristics, self-efficacy and involvement, were able to confirm a positive(+) causal relationship with the attitude of accepting digital transformation, and knowledge initially expected a positive(+) causal relationship with the attitude of accepting digital transformation, but the result was a negative(-) causal relationship, so that the hypothesis was rejected. Second, among the characteristics of innovation, complexity has a negative(-) causal relationship with the attitude of accepting digital transformation, and relative advantages and technological innovation have a positive(+) causal relationship with the attitude of accepting digital transformation. Finally, among the environmental characteristics, government regulations and competitor pressure, confirmed a positive(+) causal relationship with the attitude of accepting digital transformation. In addition, it was found that the attitude of accepting digital transformation had a positive(+) causal relationship with personal acceptance and social acceptance of digital transformation.

Smart TV is expected to take the center stage of the recent "smartization" trend in IT and consumer electronics as it performs a hub for various smart IT devices, such as smart phone, smart pad, PC, etc. It is distinct from traditional TVs or even IPTVs in the sense that it provides immersive and interactive experiences via apps downloaded through TV app store. Smart TV could serve as a new intermediary device between other smart devices and the Internet. While it started experiencing a rapid growth, little research has been conducted to understand this emerging technology in terms of its user acceptance and adoption by users. The current research attempts to fill the gap in the field by examining factors and processes for this new technology to be adopted by users. This paper draws on theories of IT acceptance and use, such as the "Unified Theory of Acceptance and Use of Technology", to investigate factors affecting "intention to use" of smart TV. The proposed research model is analyzed using the structural equation modeling approach. Findings show that such factors as innovativeness, switching cost, switching benefit, service interface, and user interface affect users' intention to use smart TV, through effort expectation, performance expectation, and social influence. Theoretical and managerial implications are discussed.

The purpose of this study was to investigate characteristics of Blockchain to introduce Blockchain technology to the medical industry. Thus, the 5 factors such as Security, Availability, Reliability, Diversity and Economic feasibility were used as the characteristics of Blockchain, which are independent variable, based on precedent studies. Also, Technology Acceptance Model(TAM) that are widely used in the research on Acceptance Intention in order to introduce new technology accept was utilized for intervening variable and dependent variable. For the purpose of this study, the health professionals and ordinary people were classified into health care providers and medical service consumers respectively to conduct survey and comparative analysis. The researching findings discovered that Hypothesis1-1(Security-Perceived Easiness-Acceptance Intention), Hypothesis2-1(Security-Perceived Usefulness-Acceptance Intention) and Hypothesis 3-1(Security-Perceived Easiness-Perceived Usefulness-Acceptance Intention) were rejected in all participants including health professionals and ordinary people. Additionally, all characteristics of Blockchain such as Availability, Reliability, Diversity and Economic feasibility were rejected in Hypothesis3-2 and Hypothesis 3-5 that pass through Easiness and Usefulness to Acceptance Intention, in case of the medical service consumers. Thus, this study discovered and confirmed that there's difference between the health care providers and medical service in the characteristics of Blockchain, as they pass through Perceived Easiness and Perceived Usefulness to Acceptance Intention. The significance of this study can be found, as it suggested activation plan through empirical analysis, which was hardly ever used in the study on Blockchain activation.

It is necessary to establish a systematic framework where the performance of governmental funding projects can be evaluated just-in-time as well as objectively regarding IT small and medium-sized enterprises and venture business. In this study, a framework is proposed for the performance evaluation using Data Envelopment Analysis (DEA) and a case study is illustrated with an empirical dataset. Especially, in order to enhance the reliability of optimal solutions, a DEA/AR-I revised model is developed by adding Acceptance Region (AR) Type I constraints into the DEA basic model. Based on the procedure and the models, it is considered that an 'efficiency score' can be calculated as a guideline for conducting successive performance evaluation processes fast. As for major governmental funding projects with respect to 'IT SMERP 2010 Plan', performance evaluations are discussed concerning between projects as well as between corporate entities within each project.

There can be analyzed severally on the acceptance conditions of freight forwarder's transport document under UCP. First, Bills of Lading issued by forwarding agents will be refused. This can be seen in the article 20 of 1933 Revision UCP(Brochure 82) and the article 20 of 1951 Revision UCP(Brochure 151). Second, Unless specifically authorized in the credit, Bills of Lading issued by forwarding agent will be rejected. It is prescribed in the front part (a) of article 17 of 1962 Revision UCP(Brochure 222) and the article 19 of 1974 Revision UCP(Publication No. 290). Third, Acceptance conditions are different according to the type of transport documents, that is either Bill of Lading or not. It is prescribed in the art 25 and article 26 of 1983 Revision UCP. Unless otherwise stipulated in the credit, transport document issued by a freight forwarder will be rejected unless it is the FIATA Combined Transport Bill of Lading approved by the International Chamber of Commerce or otherwise indicates that it is issued by a freight forwarder acting as a carrier or agent of a named carrier. On the other hand, unless otherwise stipulated in the credit, marine bill of lading issued by a freight forwarder will be rejected, unless it indicates that it is issued by such freight forwarder acting as a carrier, or as the agent of a named carrier. Fourth, transport documents issued by a freight forwarder will be accepted. This can be found in the article 30 of 1993 Revision UCP(ICC Publication No. 500) and the article 14 l of 2007 Revision UCP(ICC Publication No. 600). According to the former unless otherwise authorized in the Credit, transport document issued by a freight forwarder will only be accepted if it is appears on its face to indicate the name of the freight forwarder as a carrier or multimodal transport operator or its agent. The latter prescribed that a transport document will be accepted if it is issued by a freight forwarder by a agent of carrier or freight forwarder itself.
