The comprehension of water-level behavior in rivers is essential for effective flood and river environmental management. The objective of this study is to propose a methodology that can be used by field engineers engaged in actual practice, to readily identify the characteristics of water-level behavior during flood events. To this end, a total of 45 historical water-level records from 2010 to 2022 year, which provide flood information for the flood vulnerable districts of the Han River, were obtained. A Water-level Rise Behavior Curve (WRBC) was developed and suggested to quantify the amount of water-level rise per unit time during flood. As a result, the water-level rises by more than 80% of the total rise within the first 6.2 hours, followed by a gradual rise. The time required to achieve a particular equilibrium varied depending on the area and runoff characteristics of the upstream. Furthermore, the study revealed that the WRBC provides a statistical representation of the water-level rise trend during floods, and can be effectively utilized for flood mitigation measures in waterfront spaces and irrigation facilities.

Purpose: In order to increase the quality of nursing care for patients with diabetes mellitus, it is important for clinical nurses to accept changes in diabetes knowledge and correct their approach immediately. This approach will also contribute to effective nursing practice. Methods: The study was designed to investigate the level of knowledge and diffusion of knowledge for nursing care of patients with diabetes mellitus among clinical nurses. It was conducted with nurses from 29 general hospitals in Korea from November 3 to December 5, 2008. The questionnaire consisted of 129 items and it was sent to the participants by mail. Of the 1,060 questionnaires returned, only 930 were valid for use in the statistical analysis. Results: 1) The average score for clinical nurses' knowledge of diabetes mellitus was 0.67 out of 1.0. 2) The level of persuasion of knowledge for nursing care of patients with diabetes mellitus averaged 0.64 out of 1.0 3) The level of practical application of knowledge for nursing care of patients with diabetes mellitus averaged 1.05 out of 2.0, indicating that they applied their knowledge 'sometimes'. 4) The level of diffusion of knowledge for nursing care of patients with diabetes mellitus was 2.37 out of 4.0 and level was estimated as the stage of 'persuasion'. 5) There were significant differences in nursing knowledge of diabetes mellitus, according to experience in practical education for diabetes mellitus. Conclusion: The results indicate that nurses with a lower level of knowledge of diabetes mellitus have a lower level of persuasion of knowledge for nursing care of patients with diabetes mellitus and lower practical application. To improve the level of nurses' knowledge of diabetes mellitus, practical training programs are needed for areas in which knowledge level is low, such as 'diagnosis and management of diabetes mellitus', 'oral diabetes medication', and 'glucose control in special conditions'.

The present study investigates the non-linear soil-pile interaction using three-dimensional (3D) non-linear finite element models. The numerical models were validated by using the results of extensive pile load and shaking table tests. The pile performance in liquefiable and non-liquefiable soil has been studied by analyzing the liquefaction ratio, pile lateral displacement (LD), pile bending moment (BM), and frictional resistance (FR) results. The pile models have been developed for the different ground conditions. The study reveals that the results obtained during the pile load test and shaking cycles have good agreement with the predicted pile and soil response. The soil density, peak ground acceleration (PGA), slenderness ratio (L/D), and soil condition (i.e., dry and saturated) are considered during modeling. Four ground motions are used for the non-linear time history analyses. Consequently, design charts are proposed depended on the analysis results to be used for design practice. Eleven models have been used to validate the capability of these charts to capture the soil-pile response under different seismic intensities. The results of the present study demonstrate that L/D ratio slightly affects the lateral displacement when compared with other parameters. Also, it has been observed that the increasing in PGA and decreasing L/D decreases the excess pore water pressure ratio; i.e., increasing PGA from 0.1 g to 0.82 g of loose sand model, decrease the liquefaction ratio by about 50%, and increasing L/D from 15 to 75 of the similar models (under Kobe earthquake), increase this ratio by about 30%. This study reveals that the lateral displacement increases nonlinearly under both dry and saturated conditions as the PGA increases. Similarly, it is observed that the BM increases under both dry and saturated states as the L/D ratio increases. Regarding the acceleration histories, the pile BM was reduced by reducing the acceleration intensity. Hence, the pile BM decreased to about 31% when the applied ground motion switched from Kobe (PGA=0.82 g) to Ali Algharbi (PGA=0.10 g). This study reveals that the soil conditions affect the relationship pattern between the FR and the PGA. Also, this research could be helpful in understanding the threat of earthquakes in different ground characteristics.

This study explored the effect of corporate field teacher and corporate education satisfaction on apprenticeship education satisfaction and student job competency development focusing on NCS job standards and industry-academia-integrated apprenticeship school project group. As a result of the study, satisfaction with corporate field teachers in the electrical, electronic, and food service sectors was found to have a positive influence on improving students' job competency, while satisfaction with corporate education was important in the management, accounting, office, and information and communication sectors. In the analysis by type of project group, the satisfaction of corporate field teachers in the joint practice type and industry-led type had a strong influence on improving job competency, but in the base school type and single school type, corporate education satisfaction had a greater influence on capacity improvement. Therefore, it is necessary to redefine the competencies of corporate field teachers and to establish and implement an industry-academic integrated apprenticeship school operation plan with the relationship between the type of project group and NCS job standard classification.

Design Value Engineering (VE) has become an import part of the daily design process since it has been introduced in the construction industry. Design VE is usually conducted in the general and execution design stages respectively. In order to increase the effectiveness of the VE process, the outcome from the general design VE activities should be integrated into execution design. The outcome from the execution design should be used again for construction. In this study, a consecutive VE process model has been presented as a way to improve the current practice of design VE activities in the construction industry. In the presented model, follow-up activities are emphasized to increase values from the life-cycle perspective of a construction project. The model was tested in a case study of an actual design VE process. The result of the study demonstrates that the model can: 1) effectively incorporate owners requirements; 2) assist decision making in selecting better construction; 3) increase the interface between general and execution design stages; and 4) trace the value flow more efficiently. Overall, the study results indicates that a the consecutive VE process model can be effectively applied when construction project are contracted for the life-cycle management of construction projects.
