The COVID-19 pandemic has posed significant community challenges towards higher education around the world. The urgent and unexpected request for full-time university courses to switch over to online teaching was a particular challenge. Online learning and learning imply a certain pedagogical knowledge content (PKC), mainly related to the design and organization for better learning and the creation of unique learning environments using digital technologies. With the help of the present academic paper, we provide some expert opinion on the PKC connected with online learning with the aim of helping non-university professionals (that is, those with lack of online learning experience) navigate these challenging times. Our findings point to the planning of learning activities with certain features, a combination of three types of presence (social, cognitive and facilitative) and the need to adapt the assessment system to new learning requirements. We will conclude by contemplating on how responding to a crisis can improve teaching and learning practices in the post-digital era.

With the increasing application of UAVs in intelligent transportation systems, vehicle detection for aerial images has become an essential engineering technology and has academic research significance. In this paper, a vehicle detection method for aerial images based on the YOLOv4 deep learning algorithm is presented. At present, the most known datasets are VOC (The PASCAL Visual Object Classes Challenge), ImageNet, and COCO (Microsoft Common Objects in Context), which comply with the vehicle detection from UAV. An integrated dataset not only reflects its quantity and photo quality but also its diversity which affects the detection accuracy. The method integrates three public aerial image datasets VAID, UAVD, DOTA suitable for YOLOv4. The training model presents good test results especially for small objects, rotating objects, as well as compact and dense objects, and meets the real-time detection requirements. For future work, we will integrate one more aerial image dataset acquired by our lab to increase the number and diversity of training samples, at the same time, while meeting the real-time requirements.

Recently, the call for better accountability and social responsibility from corporations has been regularly voiced, both in the academic literature and in public discussions. This poses a challenge to the existing literature in understanding consumption behaviors to direct them toward sustainable development. This study investigates the purchase intention of Gen Z consumers in Vietnam with green packaging products. Data were collected from 914 respondents by online questionnaire and then analyzed using OLS. The results suggest the significant influence of customers' income and packaging in driving customers' intention to use environmentally-friendly products. Specifically, consumers in a higher income class participate more actively in green purchases. However, problems associated with inadequate packaging are also illustrated, resulting in the poor perception of green messages and poor practice of ecological actions. Besides, subjective norms and green trust are found to be adversely related to green consumer intention. In addition, gender disparity in green behavior is reported, where female consumers show a higher tendency to ecological consumption than their male counterparts. Other demographic factors are also included in the model as control variables, which are age, education, price, environmental literacy, environmental concern, and psychological awareness, but they do not have a significant impact on green purchase intention.

Purpose - When recovered through arbitration a contractual penalty that is disproportionately high can become grounds for challenging an arbitral award or an obstacle to its enforcement within Russian jurisdiction. This article investigates how violation of the principle of proportionality can affect the enforcement and challenging of arbitral awards in Russia. Based on the examination of the current legislation, along with the analysis of recent court cases on the subject, the ultimate object of this article is to discern practical recommendations for Korean practitioners who are looking to challenge and/or enforce arbitral awards in Russian courts. Design/methodology - The research process included the reviewing of current Russian legislation conducted in concurrence with academic literature review, searching and analyzing recent court cases where the relevant legal provisions and concepts were applied, and formulating practical implications of the research at its final stage. Findings - Through its relation to the principle of fairness/justice the authors establish the connection between the principle of proportionality and the public policy of Russia. Analysis of recent court cases showed two conflicting trends of whether a disproportionate penalty can be considered a public policy violation. The authors offer practical recommendations on how to substantiate a relevant claim regarding contractual penalty reduction by the court, depending on the desired outcome. Originality/value - The article contains an up-to-date summary of the legal provisions on the principle of proportionality of civil liability in Russia and identifies the most recent trends in court practice on the issue that is not covered by existing studies.

Recently, the platform industry is rapidly growing in the global market, and competition is intensifying at the same time. Therefore, in order for domestic platform companies to have global competitiveness in the platform market, it is necessary to study the platform business ecosystem and success factors. However, most of the recent platform-related studies have been theoretical studies on the characteristics of platform business status analysis, platform economy, and indirect network externalities of platforms. Therefore, this study comprehensively analyzed the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzed the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. And based on these factors, an IPA analysis was conducted as a way to propose a success plan to stakeholders in the platform business ecosystem. As a result of the analysis, among the success factors collected through previous studies, manpower, capital, and challenge culture were identified as factors that are relatively well maintained in both importance and satisfaction in Silicon Valley. In the end, it can be seen that the creation of an environment and culture in which Silicon Valley can use it to challenge itself based on excellent human resources and abundant capital contributes the most to the success of Silicon Valley's platform business. On the other hand, although it is of high importance to Silicon Valley's platform corporate ecosystem, the factors that show relatively low satisfaction among stakeholders are 'learning and benchmarking among active companies' and 'strong ties and cooperation between members', and it is analyzed that interest and effort are needed to strengthen these factors in the future. Finally, the systems and policies necessary for market autonomous competition, 'business support service industry', 'name value', and 'spin-off start-up' were important factors in literature research, but the importance and satisfaction of these factors were lowered due to changes in the times and environment. This study has academic implications in that it comprehensively analyzes the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzes the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. In addition, there is another academic implications that importance and satisfaction were simultaneously examined through IPA analysis based on these various extracted factors. As for academic implications, it is meaningful in that it contributed to the formation of the domestic platform ecosystem by providing the government and companies with concrete information on the success factors of the platform business ecosystem and the theoretical grounds for the growth of domestic platform businesses.

When we assume the transition to a knowledge management society, what factors should be differentially added to the characteristics of CEOs of small enterprises to enhance management performance? This can be done by measuring the core competence of the CEO who is an importance asset of the small firms. This study focuses on the following four inquiries to clarify the relationship among the core competence of the CEO, the knowledge management and the performance of the firms. First, we test the influence of the core competence of CEO on business performance. Second, we explore the effects of CEO characteristics on the knowledge management and the performance of the firm. Third, we test whether knowledge management has a mediating effect in the relationship between the characteristics of CEO which is a parameter, and the business performance of the firm which is a dependent variable. Fourth, for the sake of a deeper understanding of the CEO of the small firms, we conduct t-test or multiple comparison to find out the statistically significant differences among means of the main variables such as demographic characteristics, work experience, and entrepreneurship. The academic contribution of this study is to verify the characteristics of the CEO, which influence the business performance:the global competence, challenge spirit, interpersonal flexibility and stress tolerance, in connection with the knowledge management of small firms. The practical contribution of this study is to test whether CEOs can demonstrate successful business performance through knowledge management rather than measuring business performance after a certain period of time through profit and loss statements in this era of uncertainty.

This article is a preliminary essay for comparative study on Lao Zi Note of Park Sae Dang who lived Lee Dynasty in 17C and Hayashi La Zan who lived Doku Kawa Bakuhu in 17C. This article have two points at issue. First one is the their challenge that resisted the dogma of their own age. And the other one is their challenge of thaught had the academic background of the Lao Zi Note. They had a their own Lao Zi Note, Park Sae Dang朴世堂 had a New Note of Lao Zi 新註道德經 and Hayashi La Zan 林羅山 had a Selection Note of Lao Zi 老子抄解. However there are some different points between Park Sae Dang and Hayashi La Zan. The Hayashi La Zan's comprehension of Lao Zi followed in Lao Zi Note of Lin Xi Yi 林希逸 who had a point of Confucian comprehension of Lao Zi, so the study of Taoism of Hayashi La Zan excepted Zhuang zi. Hayashi La Zan concentrated on only Confucian comprehension of Lao Zi because Lin Xi Yi's Note of Zhuang Zi had a point of Zen Buddhism. However Park Sae Dang's the study of Taoism has Lao Zi and Zhuang Zi. He understood Lao Zi and Zhuang Zi in a base on Confucian comprehension. He indicated Confucian moral principle 修身治人 for a equal point of between Confucianism and Taoism. And he understood Cheng Xin成心 in Qiwulun in Zhuang Zi is similar to Xing性 of Xing Shan性善 in Meng Zi. Park Sae Dang analyzed not simply Lao Zi but also Zhuang Zi in a base on Confucian comprehension.
