  • The purpose of this study was to overcome the nursing staff shortage crisis at small and medium sized hospitals by examining the mediation effects of organizational commitment and job satisfaction on the relationship between job stress and turnover intention. To do so, this study used Price’s voluntary turnover model and suggested an integrated model by exploring the moderated mediation effects of changes in self–efficacy. Methods: The survey was conducted with 344 nurses working at small to medium sized hospitals in C city. Data collection was conducted for two weeks, from June 1 to 15, 2016, and the collected data were analyzed using Hayes’ macro process models 4 and 8 in SPSS 22.0. Results: The findings indicated that organizational commitment and job satisfaction have indirect effects on the relationship between job stress and turnover intention. Self-efficacy was found to have a moderation effect between job stress and mediating variable pathways and also have a mediation effect on job satisfaction pathways. Conclusion: In order to reduce the turnover intention of nurses in small to medium sized hospitals, it is necessary to develop a practical self-efficacy improvement program and action plan for the nursing work place.

  • With radical development of information and communication Technology, Internet of Things(IoT) era has come. All the things around us are connected through internet so that it enables objects to exchange data with connected devices and is expected to offer new advanced services that goes beyond the value where each existing objects could have offered respectively. Concerns regarding security threat are being raised in adopting IoT as the number of internet-connected appliances are rapidly increasing. So, we need to consider how to protect and control countless objects. However, traditional security systems including intrusion detection systems(IDSs), firewalls(FWs), anti-viruses(A/Vs), etc., focus on low level attack or anomalies, and raise alerts independently. And IoT services have different types of security frameworks. As a result, it is difficult for human security manager or attack response systems to understand the alerts and take appropriate actions. In this paper describes the analysis of security methods in the area of IoT and describes a mechanism that analyzes logs generated by IoT devices attacks. Data collected from the lightweight application is sent to the network component for further analysis. The collaborative component is used for collecting data in the distributed network and indicates the possible attacks. Also this paper suggests enterprise security management including IoT services which are based on distributed environments, and presents a practical technique to address this issue, and introduces Event Correlation Model(ECM) which is a simple free text causal language. We show how the concept of class in object-oriented methodology is used to provide scalability to our approach. Graph and coding theories are used for correlation.

  • Purpose: The study induced obesity in 50-week-old white rats with high fat intake for eight weeks. Then for 12 weeks, we analyzed how resistance exercise with anaerobic properties and fermented soybean ingestion with a nutritional approach affect the potential mechanisms underlying body composition, metabolic risk factors, and inflammatory cytokine of aortic tissue. Method: The experimental animals were randomly assigned to four groups: Control(Con), Soybean(Soy), Resistance Expense(Re), and Soybean + Resistance Expense(Soy+Resistance). For the resistance exercise, the ladder climbing is applied, and the soy supplement made up 24% of the total calories of soy protein. After eight weeks of high-fat diets, obesity was induced and treated for 12 weeks. The appearance of inflammatory cytokine was analyzed for IL-6, TNF-α, IL-10, and IL-4 in the aortic tissue. Results: In Soy and Soy+Re groups, the fat content decreased compared to those in Con and Re groups(Figure 2A), and body fat was higher in Soy and Soy+Re groups than in Con and Re groups. The appearance of IL-6 cytokine associated with infectious diseases showed significant differences in Soy, Re, and Soy+Re groups over Con groups(p <0.05). The appearance of other cytokine, such as TNF-α, IL-4, and IL-10, showed no significant differences between the groups. Conclusion: As a result, the positive effects of fermented soybean ingestion on changes in inflammatory factors associated with vascular inflammation cannot be clearly identified in improving the function in the aortic tissue. Therefore, since it cannot be seen as a positive effect, it is necessary to choose the intake and type according to the purpose of the ingestion and to apply it compiling prior studies and literature regarding the form, frequency, intensity, and time settings of exercise.

  • Purpose: The outbreak of public health crisis of COVID-19 has caused the Chinese sports industry to suffer a "cold winter" and turned into stagnation from rapid development. Although China's sports industry has been gradually restored under the leadership of the government after the epidemic has been effectively controlled, the internal problems exposed by COVID-19 are still worth pondering. These problems will not only impede the further development of China's sports industry, but also make it difficult to cope with other public health emergency crisis. Method: This study researched the impacts of COVID-19 on Chinese sports industry through literature review and data collation, so as to reflect the existing problems in Chinese sports industry and put forward corresponding suggestions. Results: Through summarizing the current situation of impacts, it found COVID- 19 had negative impact on sports competition performance, sports fitness and leisure activities, sports tourism services and education and training industry of sports industry. It caused huge economic losses, even hinders the continue development of these industries. Through the specific analysis of the current situation, this paper believed that the huge losses on small and medium-sized sports enterprises was the reason caused such serious consequences. The reasons are as follows: (1)small and medium-sized sports enterprises lacked plans and capabilities to deal with public health emergency crisis due to their small sale and weak assets; (2)In order to control the spread of COVID-19, Chinese people have adopted a semi-closed life. The loss of physical consumers has a fatal shock to small and medium-sized sports enterprises with a single business model; (3)Small and medium-sized sports enterprises are unable to quickly and effectively resume normal operation after the epidemic situation is under control due to their insufficient recovery capacity. Conclusion: In order to solve the existing problems, the development suggestions about government dominantion, enterprises assist for small and medium-sized sports companies are proposed. The suggestions are as follows. (1)public health emergency crisis plan for small and medium-sized sports enterprises is established in China to ensure that small and medium-sized sports enterprises can make timely and effective response when public health emergency crisis happens. (2)diversified online business is conducted based on big data and the Internet by small and medium-sized sports enterprises under the premise of effective supervision, so as to solve the problem of single operation mode and poor pressure-resistant ability of small and medium-sized sports enterprises. (3)epidemic sports industry insurance is carried out to create GDP and enhance the ability of small and medium-sized sports enterprises to resume normal operation.
