Purpose: This study aimed to investigate the impact of a nurse shift improvement pilot project on nurses' shift adjustment, work-life balance, and turnover intention, as well as nurses' experiences of participating in the pilot project. Methods: An explanatory sequential mixed-methods study was performed. Survey data was collected from a total of 1,051 nurses both in participant and non-participant groups. For the qualitative study, focus group interviews were conducted with 22 nurses who participated in the shift improvement pilot, including 12 staff nurses, 7 nurse managers, and 3 substitute nurses. Results: There were significant positive effects on the key variables of nurses' shift adjustment, work-life balance, and turnover intention in the group that participated in the nurse shift improvement pilot project. Based on the qualitative study, participants in the shift improvement pilot project indicated that it enabled nurses to recover their circadian rhythm, and achieve a better work-life balance, and they wanted to continue working as a nurse, and hoped expanded application of the pilot project. Conclusion: In order for expanded implementation of the pilot project and continued improvement in the shift system, we recommend establishing compensation standard, systematizing the use of substitute nurses, developing guidelines for shift schedules, and expanding the shift improvement pilot project to other departments such as the emergency room.

Now many metropolitan electric railways are being constructed on the metropolitan area. But railways now in service have some inefficiency. These railways are operated like subways, for example, all slow trains and fixed train set. So this paper proposes the methods of improvement. For making rapid train, it is showed ' philosophy of rapid train ' that makes rapid train to be main service. And for effective operation, it is introduced flexible train set and 'separation-unification operation'. And for smart railway tracks, it is introduced making loop track and direct connection track between radiating and circular railways. By these methods, a master plan of improvement of metropolitan electric railways is made and vision of the railways becomes common to passengers.

The application of stabilization method has increased because of short construction periods, no environmental problems with dumped and replaced soil, assurance of required strength and economical effect with mid to small size construction. The unconfined and triaxial(UU-condition) compression tests were executed with each mixing sample for the study of the improvement effects and the effect of design-parameters by the stabilization methods. Three typical stabilizers, which are representative in Korea, were applied in this study, and three common soils(very soft clay, general weathered soil, common clay), which are common in Korea, were used in this study. In this study, the effect of engineering factors(soils, stabilizers and water contents, etc.) which are important parameters for the improvement effects of mixed ground by stabilizers, was analyzed. As results, the tendencies of design-parameters(unconfined compression strength, deformation modulus and strength parameter) are presented and the criteria of the application of stabilization methods are suggested.

Purpose: The predominant approach for mitigating inadequate sampling rates has primarily involved bolstering the volume of education. This study aimed to curtail inadequate sampling rates through the implementation of continuous quality improvement (CQI) activities, tailoring effective methods to the unique needs of each institution. Methods: We developed a sample handling guidebook and implemented QI activities to address this issue. Results: These measures resulted in a 4.7% decrease in inadequate sampling rates, concurrently improving knowledge of sample handling and overall nurse satisfaction. We addressed the root causes of inadequate sampling before laboratory pre-processing by: 1) focusing on systematic rather than erratic errors through CQI activities, 2) revising the sample handling guide, and 3) delivering face-to-face education based on the specific needs of the nursing department. These changes resulted in an additional 0.6% decrease in the inadequate sampling rate. Conclusion: This study demonstrates that the implementation of CQI activities based on evidence derived from a multifaceted causal analysis significantly reduced the inadequate sampling rate compared to previous studies.

This study aims to analyze the on-site improvement area of residential environment improvement project based on research results derived from the on-site and questionnaire survey in case of Daegu. The main findings are as follows. First, residents complain about delay of project completion because a long time has been passed after on-site improvement area was designated. Experts and government officials agree that a new method of development is required. Second, future development should discriminate on-site improvement area according to its level of project completion. The area should be classified into project completion areas and on-going area, and new methods, such as redevelopment, apartment-housing construction method, should be allowed. Third, for better management of on-site improvement area, laws and regulations must be ready and government's will for improvement is crucial.

In this paper, we present a fast and efficient Iterative Improvement Partitioning(IIP) technique for VLSI circuits and hybrid bucket structures on its implementation. The IIP algorithms are very widely used in VLSI circuit partition due to their time efficiency. As the performance of these algorithms depends on choices of moving cell, various methods have been proposed. Specially, Cluster-Removal algorithm by S. Dutt significantly improved partition quality. We indicate the weakness of previous algorithms wjere they used a uniform method for choice of cells during for choice of cells during the improvement. To solve the problem, we propose a new IIP technique that selects the method for choice of cells according to the improvement status and present hybrid bucket structures for easy implementation. The time complexity of proposed algorithm is the same with FM method and the experimental results on ACM/SIGDA benchmark circuits show improvment up to 33-44%, 45%-50% and 10-12% in cutsize over FM, LA-3 and CLIP respectively. Also with less CUP tiem, it outperforms Paraboli and MELO represented constructive-partition methods by about 12% and 24%, respectively.

Generally it is informed that urethane materials are superior to the others in physical characteristics, durability, ground improvement and the influence to environment . But, the existing urethane methods are too expensive to apply. So this study has analyzed the applicability of TAS method which has developed the existing urethane injection mechanism. From the results, Extending the max-infection distance over l0m from 6m which the existing methods could inject to, TAS method has proved to be economical. Also, the TAS method is obtained quickly to ground improvement effect in various tunnel constructions because rise-time was relatively shorter than that of cement-grouting. Therefore, it is expected that TAS method would be applied a lot for water proof and ground improvement etc. owing to its many advantages mentioned the above.
