This study explored a structural model that predicted the influencing factors of GRIT and job crafting on the organizational effectiveness of organizational commitment and job satisfaction of medical center employees and verified the relationship between them. This study was conducted on 450 subjects, including doctors, nurses, administrative staff, and technical health service staff working at a university-affiliated hospital, from June 1, 2020 to June 15, 2020, and collected data were analyzed using SPSS 26.0 and AMOS 26.0. The results of this study showed that the higher the GRIT, the more active the job crafting(β=.751, p<.001), which appeared to have a positive effect on organizational commitment (β=.297, p=.005) and job satisfaction(β=.353, p<.001). Although the GRIT of medical center employees did not show a direct effect on organizational commitment and job satisfaction, indicators of organizational effectiveness and employees' job crafting thoroughly played an intermediary role in the relationship between GRIT and organizational effectiveness. These results are expected to be utilized as useful information in developing measures for human resources management of medical center employees.

Since the V-World, the Spatial Information Open Platform service, has started in 2012, a lot of people have increased explosively every year with their interest. It is necessary to know the specific service status in order to serve as indicators of the improvement of user's environment and the service to be added in the future based on the user's increasing need. However, there is difficulty to figure out more specific service status, such as the usage of hardware resources for 2D / 3D / Portal services and the actual user usage patterns, because the current system does not have the real-time monitoring system. Therefore, in this paper, through the analysis of the usage of system resources for 2D / 3D / Portal services based on web server log and the usage of hardware resources such as CPU, Memory based on system log, we analyze the usage of service in 2015 and compare with the results of the 2014, to present problems of the current system and the solutions about the problems.

We conducted a systematic review to summarize providers' attitudes toward pay-for-performance (P4P), focusing on their general attitudes, the effects of P4P, their favorable design and implementation methods, and concerns. An electronic search was performed in PubMed and Scopus using selected keywords including P4P. Two reviewers screened target articles using titles and abstract review and then read the full version of the screened articles for the final selections. In addition, one reference of screened articles and one unpublished report were also included. Therefore, 14 articles were included in this study. Healthcare providers' attitudes on P4P were summarized in two ways. First, we gathered their general attitudes and opinions regarding the effects of P4P. Second, we rearranged their opinions regarding desirable P4P design and implementation methods, as well as their concerns. This study showed the possibility that some healthcare providers still have a low level of awareness about P4P and might prefer voluntary participation in P4P. In addition, they felt that adequate quality indicators and additional support for implementation of P4P would be needed. Most healthcare providers also had serious concerns that P4P would induce unintended consequences. In order to conduct successful implementation of P4P, purchaser should make more efforts such as increasing providers' level of awareness about P4P, providing technical and educational support, reducing their burden, developing a cooperative relationship with providers, developing more accurate quality measures, and minimizing the unintended consequences.

The MEPDG(Mechanistic-Empirical Pavement Design Guide) developed based on the AASHTO Design Guide helps engineers find optimal alternatives by using traffic volume, climate, material property, and pavement structure as its input parameters. However, because technical problems were found in the MEPDG, efforts to improve the program by settling the problems have been continued. Meanwhile, another mechanistic-empirical design program has been developed by the KPRP(Korea Pavement Research Program) in Korea. To develop and improve the Korean design program reasonably, it is necessary to analyze the MEPDG and then compare programs each other. For concrete pavement, fatigue cracking is predicted by using very complicated logic different from other performance indicators. Therefore, in this paper, transfer functions of the fatigue cracking used in the version of 0.5, 1.0, and 1.1 of the MEPDG were analyzed. Sensitivity of the input parameters to the cumulative fatigue damage was compared to each other by the MEPDG version and KPRP.

A more efficient use of nutrients can benefit both farmers and water quality. To propose an establishment scheme for official standards for liquid fertilizer from swine manure slurry, we evaluated previous and present data related to swine manure as well as analyzed 101 swine manure samples collected from 28 public livestock recycling centers throughout the nation. From these investigations, we found that the official standards for byproduct fertilizers set by the Rural Development Administration (RDA), especially for a liquid swine manure fertilizer, should be revised due to nutrient content requirements having to meet at least 0.3% content for the sum of nitrogen, phosphorus, and potassium. Otherwise, most of the swine manure cannot be utilized as a liquid fertilizer because the result of the 101 samples' analysis showed fewer than 28% of them met the minimum standard of ${\geq}0.3%$ content for the sum of nitrogen, phosphorus, and potassium, while the contents of heavy metals as indicators of toxicity met the standard requirements. Therefore, it is suggested that official standards for byproduct fertilizers set by RDA should be revised as follows: no limit for nutrient contents and addition of chloride as homogeneity. Also, NaCl should be changed to Na because NaCl cannot be analyzed by instrument.

Background: Fatigue is pervasive, under-reported, and potentially deadly where flight operations are concerned. The aviation industry appears to lack a standardized, practical, and easily replicable protocol for fatigue risk assessment which can be consistently applied across operators. Aim: Our paper sought to present a framework, supported by real-world data with subjective and objective parameters, to monitor aircrew fatigue and performance, and to determine the safe crew configuration for commercial airline operations. Methods: Our protocol identified risk factors for fatigue-induced performance degradation as triggers for fatigue risk and performance assessment. Using both subjective and objective measurements of sleep, fatigue, and performance in the form of instruments such as the Karolinska Sleepiness Scale, Samn-Perelli Crew Status Check, Psychomotor Vigilance Task, sleep logs, and a wearable actigraph for sleep log correlation and sleep duration and quality charting, a workflow flagging fatigue-prone flight operations for risk mitigation was developed and trialed. Results: In an operational study aimed at occupational assessment of fatigue and performance in airline pilots on a three-men crew versus a four-men crew for a long-haul flight, we affirmed the technical feasibility of our proposed framework and approach, the validity of the battery of assessment instruments, and the meaningful interpretation of fatigue and work performance indicators to enable the formulation of safe work recommendations. Conclusion: A standardized occupational assessment protocol like ours is useful to achieve consistency and objectivity in the occupational assessment of fatigue and work performance.
