Despite the early success story, the pan-industry diffusion of big data has been slow mostly due to lack of confidence of the value creation and privacy-related concerns. The problem leads us to the need to a stakeholder analysis on the adoption process of big data. The present study combines technology acceptance model, task-technology fit theory, and privacy calculus theory to integrate the positive and negative factors on the big data adoption. The empirical analysis was performed based on the survey from the current and potential big data users. Results revealed perceived usefulness, task-technology fit, and privacy concern are significant antecedents to the intention to use big data. Furthermore, there are significant differences in the perceptions of each constructs among groups divided by the types of big data use, with several exceptions. And the control effect was found in the magnitude of the relation between independent variables and dependent variable. The theoretical and politic implications of the analysis are discussed as to the promotion of big data industry.

The reluctance of Latin American countries to practice international arbitration is not a new topic in international law. This reluctance historically based on Calvo Doctrine provoked not only the absence of Latin American countries from the major international commercial arbitration conventions, but obsolete national arbitration legislation. Recently, however, these countries have undertaken major steps showing that the region is no longer reluctant to practice international commercial arbitration. Most Latin American countries have ratified the 1958 Convention on the Recognition and Enforcement of Foreign Arbitral Awards ("New York Convention"), the 1965 Convention on the Settlement of Investment Disputes ("Washington Convention") and the 1975 Inter-American Convention on International Commercial Arbitration ("Panama Convention"). The majority of Latin American countries have also modified and adapted their national legislation on arbitration to the UNCITRAL model law. Even judiciary has been following this pro-arbitration. This article will focus on some of these factors provoking the acceptance of international commercial arbitration in Latin America to trace the common trends and characteristics in an attempt to understand better how international arbitration set on its place firmly. For this purpose we selected five countries, Brazil, Argentina, Chile, Mexico and Venezuela, to analyse legislations and jurisprudence. Latin America is ready to challenge any obstacles to promote arbitration as alternative methods of judicial resolution. There is an ever-increasing number of international arbitration in Latin America. Both practitioners and judiciary have shown desires to promote the resolution of disputes by arbitration and used the legal instruments to ensure that process interpreting and applying legislations for pro-arbitration. Even there remains Calvo Doctrine's culture in Latin America still now, it should be certain this culture will disappear from the conduct of international arbitration.

In concrete mix design we need the informations of the codes, the specifications, and the experiences of experts. However we can't consider all factors regarding concrete mix design. The final acceptance depends on concrete quality control test results. In this process we meet the uncertainties of materials. temperature, site environmental situations, personal skillfulness. and errors in calculations and testing process. Then the mix design adjustments must be made. Concrete mix design and adjustments arc somewhat complicated, time-consuming. and uncertain tasks. In this paper, as a tool to minimize the uncertainties and errors the neural network is applied to the concrete mix design. Input data to train and test the neural network are obtained numerically from the results of design following the concrete standard specifications of Korea. The 28-days compressive strengths which are variate according to the uncertainties and errors are considered. The results show that neural networks have a strong potential as a tool for concrete mix design.

This study examines cultural differneces in psychosocial maturity experiences between collectivistic and individualistic cultures. Personal, relational, and social dimensions were assessed to explore psychosocial maturity experience of elderly Korean residents in Korea and Canada who were psychosocially well developed through in-depth interviews and a content analysis. According to the results, there were diverse similarities and differences in the psychosocial maturity of elderly Korean residents between the two cultures. First, psychosocially mature elderly residents in both cultures showed positive self-concept and self-satisfaction. However, there were differences in their meaning. Second, in terms of interpersonal relations, the most important and satisfying relationship was the spousal relationship for both cultures, and relationships with children were satisfying. However, there were differences in the meaning of relationships between the two cultures as well as gender differences. Third, psychosocially mature elderly residents in both cultures reported psychosocial factors such as mature aging as a social dimension. Elderly residents in Korea regarded mature aging as a relationship oriented phenomenon, whereas those in Canada reported social attitudes toward mature aging. In addition, elderly residents in both cultures reported greed and harm to others as immature aging. Elderly residents in Korea regarded relational discord as immature aging, whereas those in Canada regarded it as demanding adult treatment from future generation. In terms of transcendence, adjustment was reported as living by going with the flow. Elderly residents in Korea reported adjustment based on fatalism, whereas those in Canada showed some religious meaning. Finally, psychosocially mature elderly residents showed a positive view, acceptance and life integration. These results are discussed from the perspective of cultural differences.

This study was conducted structural model analysis focusing on the factors influencing UHDTV service usage. The perceived quality, innovativeness, price sensitivity are adopted as independent variables and perceived usefulness, perceived easy use are adopted as intervening variables. Especially symbolism used it as a control variable. As a result of the analysis by PLS, the influence coefficient of perceived quality was significantly higher than other variables. However, the combined effect of symbolism and perceived quality has a negative effect on perceived usefulness, and the more the users consider the symbolism of UHDTV usage, the more negative the evaluation of UHD quality and usefulness. With the launch of the terrestrial UHDTV service in May 2017, the most important issue is the production and distribution of high-quality content that users want.

This paper aims to give an overview of the methods to inherently prevent human errors and to effectively mitigate the consequences of such errors by securing defense-in-depth during plant management through the advanced man-machine interface system (MMIS). It is needless to stress the significance of human error reduction during an accident in nuclear power plants (NPPs). Unexpected shutdowns caused by human errors not only threaten nuclear safety but also make public acceptance of nuclear power extremely lower. We have to recognize there must be the possibility of human errors occurring since humans are not essentially perfect particularly under stressful conditions. However, we have the opportunity to improve such a situation through advanced information and communication technologies on the basis of lessons learned from our experiences. As important lessons, authors explained key issues associated with automation, man-machine interface, operator support systems, and procedures. Upon this investigation, we outlined the concept and technical factors to develop advanced automation, operation and maintenance support systems, and computer-based procedures using wired/wireless technology. It should be noted that the ultimate responsibility of nuclear safety obviously belongs to humans not to machines. Therefore, safety culture including education and training, which is a kind of organizational factor, should be emphasized as well. In regard to safety culture for human error reduction, several issues that we are facing these days were described. We expect the ideas of the advanced MMIS proposed in this paper to lead in the future direction of related researches and finally supplement the safety of NPPs.

The aim of this study was to develop a scale of the Korea citizen's intentionality out of their inborn ability and mission. To set up the concept of the above intentionality, there have been many academic and religious studies for reference in addition to the existing productivity, Korea elderly successful aging scale, and the scale of life qualities for review. The first 57 items for questionnaires were created thereafter. The final 27 items were confirmed, which were constantly modified by a professor of statistics and corresponding author in effective response and in removing the redundant items after the first items had been reduced to 44 preliminary items through the many an item-by-item discussions with pastors, theologians and social workers. A survey was conducted around the metropolitan area and 380 records were collected. Factor analysis to verify the validity of the measurement tool was completed, and showed that there were 6 sub-factors; "recognition of being", "autonomous life", "self-completion", "initiative", "acceptance", and "economic feasibility". In addition, reliability analysis was implemented and found to be reliable because the Cronbach's ${\alpha}$ value was 0.6 or more.

The emergence of the World Wide Web (WWW) has changed the scholarly publishing system. Today, Open Access (OA) scholarly publishing offers free access and wide dissemination for research findings anytime and anywhere as an additional value for scholarly content. Despite the potentials of OA publishing, its adoption and use is still low.This paper determines factors influencing the adoption and use of OA publishing by academic staff in universities in Nigeria using an adapted Unified Theory of Acceptance and Use Technology (UTAUT). The study applies methodological triangulation by combining quantitative and qualitative approaches. The empirical data were collected from 317 academic staff in universities in southwest Nigeria. The questionnaire forms were analyzed using the Statistical Package for Social Sciences (IBM-SPSS) 19.0 version to generate descriptive statistics, Analysis of Variance, and Hierarchical Multiple Regression. Thematically, analysis also applies to the interviews. The results show that awareness, attitude, performance expectancy, Internet self-efficacy, and facilitating conditions significantly influenced the adoption and use of OA publishing. The study also reveals that due to lack of OA policy, most of the respondents did not know about OA. The findings further establish that all predictors and moderating variables jointly contributed 64.4% total variance towards the adoption and use of OA publishing. One of the implications of this study is that there is a need for adequate facilities to support adoption and use of OA publishing. The findings inform the proposed framework for improving and evaluating the adoption and use of OA publishing. The findings also have theoretical, societal, and methodological significance to all stakeholders.
