Purpose: Nowadays nursing is facing a constantly increasing shortage of employees. While there are many causes for the present nursing shortage, a major contributing factor is the revolution in fundamental values what we expect in life. An understanding of the change can assist in identifying interventions that can be used to address this crisis in healthcare. The purpose of this study is to identify the features they look for in work and the underlying factors of the work values domain. Methods: Using Q methodology, 37 nurses rated 34 selected Q-statements on a scale of 1-9. The collected data were analyzed using pc-QUNAL software. Results: The results showed that work values, which nurses indicate as most important through working, were perceived as 4 factors; 'compensation oriented', 'security oriented', 'professional role oriented' and 'freedom oriented' work value. Conclusion: Providing for these findings will result in greater job satisfaction among nurses, better nurse retention and enhanced patient care within a supportive and harmonious organization.

The work-related musculoskeletal disorders have constantly increased since it became an issue in 1996. In 2002, the Government established the risk factors analysis system in order to prevent musculoskeletal disorders. The proclamation by the Ministry of Labor defined eleven spheres of work associated with musculoskeletal disorders. As a result, business proprietors, who have workers engaged in tasks associated with musculoskeletal disorders, are required to conduct the risk factor analysis on a regular basis every three years. However, numerous issues have been raised while carrying out the risk factor analysis in various industries. One of the issues is that even though work sampling is an ideal method in risk factor analysis, most cases have selected extreme task postures, which is judged by an expert, due to limited time. This study will propose the desired direction of the risk factor analysis by comparing task assessment results between work sampling scenes and extreme task scenes.

A temporary work are lifting equipment that tower crane or lift, and temporary architectures that office building and storage in construction site. And it is main construction work that built and used temporarily like to a scaffolding, a walk plate, and a formwork. This study is to adjust breakdown structure of temporary work to introduce technical tendency. With a site manager, it is collected a detailed statement and compared. As a result to break down a tendency that temporary equipment, additional function, and direct work of temporary technique, first, existing detail technical indexes that group I, group J, group K, and group L are classified. Second, due to set up and manage to main agents in case of existing detail technical indexes that B1, B2, it is not wrong to classify. But, it is somewhat different, and therefore adjust it to same level. Finally, as a technical tendency that temporary equipment, additional function, and direct work of temporary technique, it is adjusted the others.

The purpose of this study was to examine the scope of work of femergency medical technician who can directly affect the resuscitation of emergency patients at the pre-hospital stage. As a result of the main study, the overall level of the subjects' work scope expansion averaged 3.34points(out of 5points), and among the items, 'The scope of work of emergency medical personnel should be expanded by revising the Act on emergency medical cars' was the highest. As for the difference in the expansion of the scope of work of paramedics by position, 'The current telemedicine guidance system is inconvenient to use' was the highest for emergency medical technicians, and there was a statistically significant difference(p<.01). Based on this study, it is believed that repeated studies are needed to establish and generalize the scope of work of paramedics.

The result verification that determines correctness for the work results calculated in each PC is one of the most important issues in PC grid environments. In this literature, voting-based and trust-based schemes have been mainly used to guarantee the correctness of work results. However, these schemes suffer from both waste of resource utilization and high computation delay because they can not effectively cope with dynamic computational environments. To overcome these shortcomings, we introduce the distribution information of PC resources based on credibility and availability into result verification phase. Using this information, we propose a new result verification scheme, which can determine the correctness of work results by each PC resources' credibility and cope with the dynamic changing environments by each PC resources' availability. To demonstrate the efficiency of our result verification scheme, we evaluate the performance of our scheme from the viewpoints of turnaround time and resource utilization, utilizing resource distribution information in the Korea@Home that is a representative PC grid system in domestic. We also compare the performance of our scheme with that of other ones.

Purpose : The purpose of this study was to identify the degree of work ethics of an occupational therapist and examine the correlation between work ethics and organizational commitment. In this study, we aimed to investigate the effects of occupational therapists' work ethics on organizational commitment. Through this study, we aim to determine the importance of work ethics and find a way to improve organizational commitment in occupational therapists. Methods : We conducted nationwide surveys on occupational therapists working in hospitals and other institutions from April 24, 2023 to May 30, 2023. We evaluated general characteristics, work ethics, and organizational commitment. General characteristics were analyzed using a frequency analysis. Work ethics and organizational commitment were examined using descriptive statistics. The correlation among work ethics and organizational commitment was analyzed using the Pearson correlation coefficient. Additionally, a multiple regression analysis was conducted to identify factors that affected organizational commitment. Results : The results of this study were as follows. First, the average score of work ethics was 3.32 ± .32. Second, a significant positive correlation was observed between work ethics and organizational commitment (p<.01). And as a result of the correlation between work ethics sub-factors and organizational commitment, wasted time (r=.261, p<.01), centrality of work (r=.366, p<.01), morality/ethics (r=.470, p<.01), leisure (r=.189, p<.05), delay of gratification (r=.410, p<.01), hard work (r=.437, p<.01), self-reliance (r=.233, p<.01) showed a statistically significant correlation. Third, the sub-factors of work ethics that influenced organizational commitment, including morality/ethics (𝛽=.302, p<.01), hard work (𝛽=.271, p<.01), and delay of gratification (𝛽=.205, p<.01) were identified. Conclusion : In conclusion, the results of this study underscore the importance of work ethics in influencing organizational commitment. Through this study, we recognized the importance of work ethics, which may serve as basic data to promote work ethics and improvement of organizational commitment.

Purpose - This work tries to analyze the transformation of sectoral innovation pattern as time goes by to enhance the understanding on sectoral innovative activities, particularly considering the change of the nature of knowledge, and the trend of convergence. Research design, data, and methodology - This work tries to identify main factors, which determine the output of technological innovation through the econometric analysis, utilizing the result of Korean Innovation Survey and find a stylized fact on the change of the innovation pattern. Result - As a result of estimation, some major elements show different effects for two discrete years, 2002 and 2010; in chemical industry the open information source and neutral basic research become more important with the appropriation mechanism such as patents, and in machinery industry, the importance of internal information has been getting decreased with rising importance of customers. Conclusion - This work presents that some elements show different effects for two discrete years. Among three major elements, the source of information and appropriation mechanism shows different features for both industries. This means that we should explicit consider the changing nature of innovative environment, which leads to and heavily influence whether the innovative activity would be effective or not when we design innovation strategy and innovation policy.

We consider an unlimited fluid queueing model which has Fractional Brownian motion(FBM) as an input and a single server of constant service rate. By using the result of Duffield and O'Connell(6), we investigate the asymptotic tail-distribution of the stationary work-load. When there are multiple homogeneous FBM inputs, the workload distribution is similar to that of the queue with one FBM input; whereas for the heterogeneous sources the asymptotic work-load distributions is dominated by the source with the largest Hurst parameter.
