In modern educational practices, the issue of dependence on the experience of using multimedia by students and the adoption of technologies in education, the perception of their benefits and effectiveness in blended learning is little covered. The purpose of the academic paper lies in assessing the audiovisual context of multimedia technologies, its acceptance by students in practice on the example of using video lectures in blended learning. The methodology is based on an online survey of 120 students of Ukrainian universities who have assessed the experience level in using video lectures, as well as the constructs as follows: Technology Characteristics, Fit, Perceived Usefulness, Perceived Ease of Use, Attitude, Intention to Use, Actual Use. The results show that the majority of students use video lectures to a certain extent in their training (20,8% have used technology to a certain extent, 49,2% have often used technology in training, 20% are regular users of technology). It has been revealed that most students agree with the relevance of video lectures, the accuracy of lectures, the brevity of lectures, the clarity of lectures, as well as the high quality of lecture videos. It has been estimated that 42,5% believe that lecture videos are an effective tool towards supporting students in hybrid learning. 26,7% of students consider video lectures to be appropriate technologies for online / hybrid courses. In general, 37,5% of respondents find video lectures useful; however, 35,0% do not agree with this statement. 83,3% of students have rated the high level of ease of access to video. In total, 95% of students find lecture videos easy to use. In general, positive attitude of students to video lectures has been revealed.

In this paper, I examined the history of Baizu that the Brief History presented. PRC created Baizu as one the 55 ethnic minority nations, as it "nationalized" all the people living within its territorial boundary. And it constructed the narrative of the "ethnic history" of Baizu, while it constructed the grand narrative of the history of the unified, multinational "zhonghua minzu." There are two major problems in the historical narrative of Baizu, thus constructed. First, the genealogy of the ancestors of Baizu constructed by PRC lacks sufficient historical evidence to prove it. Second, the politically-driven ethnic classification project by PRC produced ethnic minority nation, which does not have their own territory and Baizu was one of them. Because of this, the history of Baizu, who historically lived mixed with other ethnic groups together in Yunnan, cannot help but becoming a part of the larger Yunnan history, rather than constituting a history of an ethnic group. Then, what would be a historically sensible way to write a history of ethnic minorities in Yunnan, who have not transformed themselves into a modern nation? What I would like to suggest is, first, to abandon the construction of the history of Baizu as an ethnic group. I also suggest to distinguish Yunnan from China (zhongguo) as a unit of historical writing, and thus to cut the relationship between the Baizu history and the larger history of the unified, multitethnic "zhonghua minzu." The narrative of the Chinese history (history of Zhongguo), which takes the PRC's current territorial boundary as the unit of historical narrative, lacks historical objectivity. Names for historical communities survive, because they have been used by those who have lived in the communities as well as by other historical communities. Members of a certain historical community occupy distinctive historical space and share common historical experience. And their historical experience is mainly informed by political changes that affected the space that the historical community occupies. If one constructs the history of "Yunnan" as a distinctive historical space and community, which could be distinguished from the historical "China" (zhongguo), one may be able to construct the history of the people of Yunnan in its fullest sense.

Purpose: Chatbots are widely diffusing across various industries to substitute human manpower in the industry. However as researchers only develop technology that is applied to chatbot, the diffusion is slow in progress. The purpose of this study is to propose useful implications to accelerate diffusion of chatbots across industries by analyzing the perception of customers. To achieve the research purpose this study analyzes causal effect relationship between characteristics of chatbot character, service quality, individual difference, and intention to use chatbot. Methods: This study developed a survey that contains various questionnaires for each construct based on literature review. Data collected through survey was tested for convergent validity and discriminant validity and further analyzed the relationship using PLS-SEM method to verify hypotheses. Results: Trustworthiness of the chatbot character, ease of use, application design, responsiveness, customization, assurance, inertia, and previous experience have significant influence on forming user satisfaction, consumer trust, and intention to use. The others, likability, appropriateness, technology anxiety, and need for interaction were not significant in this research. Conclusion: Although the constructs of the research model was significant in previous literatures, some do not have significant effect on intention to use chatbots. Based on the results, chatbot managers will be able to develop chatbot systems which are more appealing to users and more academic researchers will focus on analyzing user perception and intention.

IT consulting is becoming a norm rather than exception in this age of smart work and information revolution. As IT consulting is one of the knowledge intensive services requiring high credence on both sides, maintaining a good trustful relationship is critical in sustenance of strategic partnership between business firms and IT service firms. Trust is known to be one of the salient constructs in service relationships. In this study, building from the social psychology literature, trust is conceptualized as two dimensions : cognitive and affective trust. Using two dimensions of trust as mediators, a research model is constructed for IT consulting specific context : relationship continuance intention as the dependent construct while expertise, service performance, reputation, relationship satisfaction and value similarity as antecedents of cognitive and affective trust. 145 data points were collected through a survey of IT service client project managers retrospectively asking their experience with IT consultants. Findings suggest that cognitive trust is associated with perceived level of expertise and service performance while affective trust with relationship satisfaction and value similarity, respectively. Interestingly, the paths from reputation are found to be statistically insignificant towards both dimensions of trust, indicating IT service context would be more practically outcome oriented than any other professional service context. Also, cognitive trust seems to maintain stronger influence on relationship continuance intention as anticipated. Implications and limitations are discussed at the end.

Due to the development of network and device, it is called mobile age that boosts various distribution routes of multi-media content and it constructs a new digital content consumption trend. N-screen is one of the new-introduced examples in the digital age and broadcasting industry believes it as a crisis and challenge as well. It becomes a ubiquitous multi-media environment that people watch multi-media content everywhere and any time they want to and competition happens beyond the boundaries such as network industry, terminal industry, pay TV market, traditional terrestrial TV, etc. And then how should the broadcasting service prepare for the N-screen business? The present research proposes a few terrestial broadcasting content strategies in the multi platform environment. First, instead of N-screen, it proposes multi platform, especially One Source Multi Platform(OSMP). Second, so-called 'Integrated Terrestrial Broadcasting OSMP Alliance(IBPA)' must be founded. Third, IBPA should support multi-tasking UX for viewers to have rich experience. Last, it becomes more important and necessary to support local terrestrial broadcasting service for public service in the multi platform age.

The youths are characterized by their reckless and ambitious behavior. They exhibit a strong tendency to make risky decisions that may jeopardize their future. These qualities are also in line with their experience-seeking behavior. As young entrepreneurs aim high in profit-seeking activities, their ethical stance may be compromised. Moreover, their money profile increases at an accelerated pace, leading them to love money even more. Quantitatively, this study was the first to investigate the behavior of young entrepreneurs in terms of their love of money, religiosity, and ethical perceptions by adopting the hadith perspective in Islamic tradition by developing the scales of all constructs. The respondents were 261 members of the Indonesian Young Entrepreneur Association in Sulawesi Selatan, Indonesia. This study also examined gender as the moderating variable. This study found that the love of money affects ethical perception negatively; on the other hand, religiosity positively affected ethics. Gender is found to moderate religiosity, but not love of money. These results signify the harmful impact of loving money too much on young entrepreneurs' ethics; furthermore, the scales developed from hadith revelation were able to capture the empirical findings significantly.
