The purpose of this study was to explore organizational justice (distributive, procedural, and interactional justice) as the antecedent of and career satisfaction by conducting an integrative literature review. In addition, this study aimed to identify organizational support for career development (i.e., organizational sponsorship) as the potential mediating variable between organizational justice and career satisfaction. Based on an integrative literature review of previous research, this study proposed the conceptual model on the relationship between organizational justice and career satisfaction along with organizational support for career development. According to the conceptual model, organizational justice can add to the pool of important antecedents of career satisfaction, and organizational support for career development could mediate the relationship between organizational justice and career satisfaction. This study contributed to the human resource development (HRD) field through investigating the relationship between organizational justice and career satisfaction in a career development context in the workplace. Further, this study provided additional theoretical backgrounds to conduct organizational justice related research on diverse factors, such as potential mediating variables, influencing career satisfaction.

Fast developing digital technology is Having an enormous societal influence, creating a porous new world without boundaries. This phenomenon applies to a whole range of fields, including culture, politics and even our daily lives. Urban Street cannot be excluded from this world-transforming change. Digital technology is changing the physical structure, growing patterns, function and role of the Urban Street. As a result, Urban Street should now be freeing themselves from the old-world functionalism, which has been pursued uniformly under the names of rationality and efficiency. We have, then, to think about the culture of the Digital Urban Street,'that is, the digital life style, which is tangibly generated in the concrete city space, and which must be prepared for further digitalization. This paper argues that the street must be understood as a communications centre, because digital technology has created a new communications style. Also, this paper focuses on how the physical environment of Urban Street will evolve with regard to both function and appearance. In conclusion, studying the ubiquitous space, it also looks at how existing urban planning and space design should lead to the further development of Urban Street using digital technology, as well as to the role this technology will have in the future.

It is useless to say that time is precious and important. So it does when we emphasize the importance of studying the quality and efficiency of time in learning, especially in the learning of Mathematics. In this respect, this study aims to examine the overall structure of time application in the learning of Mathematics, understanding the state and problems of Mathematics education in respect of time application, and finally seeking to find the solutions for the problems. As a first step, the items below were examined for the solutions: First, the eight viewpoints of time in Mathematics education was examined and the meaning of each viewpoint was analysed. Second, the variables resulting from teachers was examined. The preconditions for mathematics education, the attitude towards Mathematics classes, viewpoints of mathematics, the forms of self-expression, the way of utterance can be considered as the variables mentioned above. Third, the variables resulting from students was examined. Learning attitude, specific activity(both meaningful and meaningless), practical uses of teaching tools, game activities, the ways of communication and problem solving can be examined as well. In conclusion, it needs to be stressed that Mathematics class should be the meaningful time for learners, parents, and teachers. The class should guarantee the satisfaction of the learners. In other words, even if physical time is applied the same to everyone, it may differ in degree of quality and value of time application according to the way one spends the time.

This research provides a new approach for implementing an educational content for Historic Education in order to provide an effective learning environment. From historic educational point of view, it is important to comprehend a historical fact in the context of the situation at that time. So, this paper suggests that the historic content should describe not only information about various relics and ruins but also historical relationship and background. In this system, we provide versatile type of contents to help learners for collecting manifold informations about their interesting era. And this system proffers natural and residential 3D environments, which give learners to understand conceivably and to think collectively. Using the interactions, the learners navigating this virtual world are able to construct their own information system through selecting a interested one among the offered contents in the system and consequently they are getting a scientific thinking power and a creative imagination.

As the interactive AI speaker becomes popular, voice recognition is regarded as an important vehicle-driver interaction method in case of autonomous driving situation. The purpose of this study is to confirm whether multimodal interaction in which feedback is transmitted by auditory and visual mode of AI characters on screen is more effective in user experience optimization than auditory mode only. We performed the interaction tasks for the music selection and adjustment through the AI speaker while driving to the experiment participant and measured the information and system quality, presence, the perceived usefulness and ease of use, and the continuance intention. As a result of analysis, the multimodal effect of visual characters was not shown in most user experience factors, and the effect was not shown in the intention of continuous use. Rather, it was found that auditory single mode was more effective than multimodal in information quality factor. In the semi-autonomous driving stage, which requires driver 's cognitive effort, multimodal interaction is not effective in optimizing user experience as compared to single mode interaction.

A congnitive shape decomposition method that agrees with human intuition is proposed for the conceptual recognition from sillouettes of objects. Descriptions specifying the structure of shape in terms of meaningful parts and relations have cognitive power and anthropomorphism. In general, man-made objects have a lot of collinear lines and regularity. For the cognitive decomposition of man-made objects, many heuristic rules based on the cognitive experimentation are applied on the context of collinerarity and regularity. The cognitive shape decomposition for the natural shape is carried out by analyzing the possible configuraitions of vertices and line segments for one concave vertex. A cost function for the configuation is designed by weighted sum of five criteria such as, the length of split line segment, the number of split line segments at concave vertex, the proximity of concave vertex, and the correspondence of vertices. These criteria are vased on the property of human perception such as proximtiy, symmetry, and simplicity. The most promising vertex os selected among three set of visible vertices by evaluating the cost function. A number of experiments conducted on the different types of shapes shows that the results correspond with human intuition.

Due to the COVID-19 pandemic, scholars at institutions of higher education around the world are transitioning their teaching, service, and research into online settings; for many this may be a new and challenging experience. While many of the best practices associated with research in traditional or face-to-face settings also apply to research in or via online settings, there are some additional challenges and nuances that researchers must adequately address and plan for due to the affordances and limitations of online settings. This paper discusses the key issues of privacy, informed consent, trust and trustworthiness, and retention through the literature and provides practical recommendations based on evidence and experience from two different online research projects. The reflections on and examples from these two research projects contextualize the above issues and act as evidence to inform research as a practice. The authors hope this evidence and practical guidance may help researchers better prepare for research in a socially distanced world.

The study examines the question of what discriminant factors may affect differences between two groups classified by researchers' satisfaction with and continuous use intention of genetic resources(microorganisms). Survey data from researchers who are using microorganisms from a gene bank was used to empirically test. The survey, covering 150 researchers, was conducted from March 26 through April 17 2015. Linear discriminant analysis was used to test the research questions described in the study. Results from the tests show that utilization value and suitability of genetic resources for researchers' R&D activities play key roles in discriminating between the two groups classified by researchers' satisfaction with and continuous use intention of genetic resources, relatively lower and higher groups. The results indicate that useful trait information of and degree in promotion of researches by genetic resources appear to be weak in discriminating between the two groups, and that novelty of genetic resources does not play a crucial role in making a distinction between the two groups. We propose some policy implications based on the results of the study.

In this study, we explored the characteristics of instrumental genesis in high school students' scientific inquiries. Twenty-three 10th to 11th graders in a science research club participated in this study. The students in 6 groups autonomously planned and performed their own scientific inquiries for one semester. Their activities were videotaped and recorded. Semi-structured interviews were conducted. Material request papers and group worksheets were also collected for analysis. The results of the study suggested that students' practices were categorized as instrument genesis. When instrument genesis did not occur, the cases at the beginning of and during the practice were described respectively. Instrumental genesis was found to appear in three categories: instrumentation; instrumentation and instrumentalization; and instrumentalization. The characteristics and details of case represented in each category were described and discussed related to affordance as the results of the study. On the bases of the results, the implications for the reconsideration of the instruments in school science inquiries are discussed.
