The costume of ritual dance in Mongolian and Korean Buddhism

This paper investigates the diversity of costumes of Buddhist ritual dance in Mongolian and Korean Buddhism. Both the Mongolian Tsam dance and the Korean Nabi dance have developed to reflect the regional characteristics of costumes and symbolic systems and are closely related as far as the ideas of rebirth and afterlife are concerned. Both the Mongolian and the Korean dance, performed by monks, display common features that symbolise the spiritual role of the monks in guiding people on their way from birth to death. The symbolism of the ritual dance costume is related to the traditional culture, in both Mongolia and Korea, but Mongolian Tsam uses more shamanistic and decorative elements based on the ceremony of shamanism, while Korean Nabi dance shows an exceptional beauty in its self-restraint

Decentralized and autonomous content overlay networking (DACON) with WiFi access points

Accessing contents from mobile devices becomes more and more proliferated and hence the need for the content dis-tribution in the pervasive environment is growing. How-ever, distributing contents in such environments taxes wire-less network operators substantially. To provide the content distribution service in a reasonable cost, we pay attention to user-deployable WiFi access points (APs). In this paper, we propose a decentralized and autonomous content overlay networking (DACON) architecture for the pervasive content distribution services, which is the overlay network architec-ture comprised of public WiFi APs. We identify and answer major challenges in realizing the content distribution ser-vice in the pervasive environment by exploiting the overlay network of public WiFi APs

WAVE: Popularity-based and collaborative in-network caching for content-oriented networks

Abstract—In content-oriented networking, content files are typically cached in network nodes, and hence how to cache content files is crucial for the efficient content delivery and cache storage utilization. In this paper, we propose a content caching scheme, WAVE, in which the number of chunks to be cached is adjusted based on the popularity of the content. In WAVE, an upstream node recommends the number of chunks to be cached at its downstream node, which is exponentially increased as the request count increases. Simulation results reveal that the average hop count of content delivery of WAVE is lower than other schemes, and the inter-ISP traffic volume of WAVE is the second lowest (CDN is the lowest). Also, WAVE achieves higher cache hit ratio and fewer frequent cache replacements than other on-demand caching strategies. Index Terms—Content chunk caching, caching strategy, content-oriented networks I

Investigation of Working Conditions and Health Status in Platform Workers in the Republic of Korea

Background: The present study aimed to analyze several aspects of the working conditions and health status of platform workers in the Republic of Korea, such as ergonomic and emotional hazards. We also compared the health status of the platform workers with that of the general population. Methods: A total of 1,000 platform workers participated in this survey from August 7 to August 17, 2022. The participants included 400 designated drivers, 400 food-delivery drivers, and 200 housekeeping managers. A face-to-face survey with a structured questionnaire was conducted by researchers who had received specific instructions. The focus of the survey extended to the work environment, encompassing factors such as workplace violence, as well as physical, chemical, and ergonomic hazards. Health-related data for the previous year were also collected, covering a range of issues such as hearing problems, skin problems, musculoskeletal symptoms, headaches, injuries, mental health issues, and digestive problems. Subsequently, we compared the health symptom data of the responders with those of the general population in the Republic of Korea. Results: Platform workers, including designated drivers, food-delivery drivers, and housekeeping managers, existed in the blind spot of social insurance, facing frequent exposure to physical and chemical hazards, ergonomic risk factors, and direct or indirect violence. The prevalence of health problems, including musculoskeletal symptoms, general fatigue, and depressive symptoms, in each occupational group was statistically higher than that in the general population after standardization for age and gender. Conclusion: The results revealed unfavorable working environment and inferior occupational health of platform workers compared with those of the general population

The COVID-19 Pandemic Response and Its Impact on Post-Corona Health Emergency and Disaster Risk Management in Republic of Korea

The COVID-19 pandemic significantly impacted the Republic of Korea’s Health Emergency and Disaster Risk Management (Health-EDRM). This study aims to examine the Republic of Korea’s response to the COVID-19 pandemic, focusing on Health-EDRM, especially human resources, health services, and logistics. Challenges in the Republic of Korea, including lack of medical workforce, confused risk communication, shortage of hospital beds, and inefficient distribution of medical resources, have been highlighted in this paper in terms of human resources, health service delivery, and logistics, which are components of Health-EDRM. It is essential to address the cooperation between the government and private sectors, the protection of occupational health and safety of medical staff during the pandemic, and strategies and technologies to scale up the health facilities, to respond to a future crisis like the COVID-19 pandemic
