Purpose: Objective Structured Clinical Examination(OSCE) has been used for clinical skill evaluation. This study was done investigate whether there are positive impact educational effects if nursing students are invited to develop OSCE modules. Method: The participants were 63 second-year students in one nursing college. Students were divided into 3 groups; the OSCE module development group(Exp1), traditional study group(Exp2), and control group(Cnt). Students were allocated according to clinical skill test scores to make the 3 groups equal. Exp1 developed OSCE modules, and Exp2 studied using traditional methods. Clinical skill tests and surveys were done to measure self-directed readiness, problem-solving ability, and self-efficacy before and after experimental treatments. Results: Clinical skill test scores increased significantly in all three groups, but Exp1 and Exp2 showed a higher clinical skill test score increment than Cnt. Self-directed readiness scores increased significantly in Exp1, but not in Exp2 and Cnt. Problem-solving ability scores increased significantly in Exp1 compared to Cont. Conclusion: Development of OSCE modules has positive educational effects for participating students in terms of clinical skill tests, self-directed readiness, and problem-solving ability.

The current establishment of city gas piping polyethylene (PE) tube used as bonding state or part of the health or safety of fusion is very important. A part of these fusion methods to determine the soundness of the short-term trials and long-term tests can be largely classified. Typical tests include short-term strength, tensile strength, impact strength, compressive strength, resiliency and compression. Polyethylene (PE) pipes installed in the domestic terms of overall penetration rate of 45% has been used. However, polyethylene (PE) pipes have reliability problems, and these occurs mostly in part by defective welding. Therefore, the test is necessary for safety. Non-destructive methods (ultrasonic testing) are difficult to be used. Therefore, Polypropylene copolymer (PP-C), polypropylene homopolymer (PP-H), and polyethylene (PE) pipe are used. Fusion of these materials is necessary in these field however, its technical, and basic research has not been studied well. In this research, short-term strength of welding parts, its tensile strength, hardness, fatigue, and microstructure have been analyzed to find the optimum process conditions to improve mechanical properties.

When bridges are constructed with lower heights from the ground, the formed channel between the deck and the ground will inevitably hinder or accelerate the air flow. This in turn will have an impact on the aerodynamic forces on the deck, which may result in unexpected wind-induced responses of bridges. This phenomenon can be referred to "ground effects." So far, no systematic studies into ground effects on the wind-induced responses of closed box girders have been performed. In this paper, wind tunnel tests have been adopted to study the ground effects on the aerodynamic force coefficients and the wind-induced responses of a closed box girder. In correlation with the heights from the ground in two ground roughness, the aerodynamic force coefficients, the Strouhal number ($S_t$), the vortex-induced vibration (VIV) lock-in phenomena over a range of wind velocities, the VIV maximum amplitudes, the system torsional damping ratio, the flutter derivatives, the critical flutter wind speeds and their variation laws correlated with the heights from the ground of a closed box girder have been presented through wind tunnel tests. The outcomes show that the ground effects make the vortex-induced phenomena occur in advance and adversely affect the flutter stability.

Purpose: To study aimed to examine the impact of the Nursing and Care=giving Integrated Service on nursing work performance, nurse' job satisfaction, and patient safety. Methods: A total of 66 nurses were selected as participants, comprising 30 nurses working in Nursing and Care=giving Integrated Service hospital ward, and 33 nurses working in a general hospital ward with a similar patient and disease group and distributed moderately. For data analysis, t-tests, ANOVA, and $X^2$ tests were conducted. Results: Nursing work performance in the Nursing and Care=giving Integrated Service ward was higher than that in the general hospital ward, but this difference was not statistically significant. Conversely, job satisfaction was lower among nurses in the Nursing and Care=giving Integrated Service ward, although again the difference was not significant. However, the Nursing and Care=giving Integrated Service ward had a significantly lower rate of safety-related accidents in patients compared to the general hospital ward. Conclusion: In order to expand and improve patient safety and other aspects of the Nursing and Care=giving Integrated Service, there is a need to establish a mediation strategy for increasing nurses' work performance and job satisfaction.

Building wind pressure coefficient transiting test is a new method to test the building wind pressure coefficient by using the wind generated by a moving vehicle, which is susceptible to natural wind and other factors. In this paper, the Commonwealth Advisory Aeronautical Research Council standard model with a scale ratio of 1:300 is used as the test object, and the wind pressure coefficient transiting test is repeated under different natural wind conditions to study the influence of natural wind. Natural wind is measured by an ultrasonic anemometer at a fixed location. All building wind pressure coefficient transiting tests meet the test conditions, and the vehicle's driving speed is 72 km/h. The mean wind pressure coefficient, the fluctuating wind pressure coefficient, and the correlation coefficient of wind pressure are used to describe the influence of natural wind on the building wind pressure coefficient transiting test qualitatively and quantitatively. Some rules, which can also help subsequent transiting tests, are also summarized.

The stone-dust is an unavoidable by-product of aggregate production, which is produced about 0.8~1.0 million $m^3$ annually. The stone-dust is currently regarded as a hazard material on environment because it is classified as an industrial waste in the Waste Management Law of Korea. At present, the stone-dust is considered as a environmentally hazardous material, and is classified as an industrial waste according to the Waste Management Law of Korea. In this study, we assessed the heavy-metal contamination of the stone-dust on surrounding environments by various leaching tests. Leaching experiments (such as Korea Standard Leaching Procedure (KSLP), Soil Environment Preservation Act of Korea (SEPAK), Toxicity Characteristic Leaching Procedure (TCLP), and Synthetic Precipitation Leaching Procedure (SPLP)) show that very low heavy metals (As, Cd, Cu, Pb, Zn, Hg) and CN are leached out, or much less than each regulatory thresholds. The resuts of the leaching test with time in acidic solution (initial pH 5 and 3) indicate that pH-buffering minerals are present in the stone-dust. These results suggest that the stone-dust can not potentially affect adverse impact on surrounding environments such as surface water, groundwater and soil etc..

This paper presents a study based on the damage due to the fatigue life of thrust ball bearings using vibratory analysis. The main contribution of this work lies in establishing a relation between modal damping and the rolling contact fatigue damage of the thrust ball bearing. Time domain signals and frequency spectra are extracted from both static and dynamic experiments. The first part of this research consists in measuring the damping of damaged thrust ball bearings using impact hammer characterization tests. In a second part, indented components representing spalled bearings are studied to determine the evolution of damping values in real-time vibration spectra using the random decrement method. Dynamic results, in good agreement with static tests, show that damping varies depending on the component's damage state. Therefore, the method detailed in this work will offer a possible technique to estimate the thrust ball bearing fatigue damage variation in presence of spalling.

Purpose: In this study an investigation was done of injuries from inpatient falls and diagnostic tests and treatment after falls to identify what factors affect the occurrence of injury from inpatient falls in a tertiary hospital. Methods: Data for this cross-sectional study were retrieved for 428 fall events from data reported between January 1 and December 31, 2015 and were retrieved from the patient-safety reporting system in the hospital's electronic health records. A multivariate logistic regression model was developed with STATA 13.0. Results: Of the patients, 197 (46.0%) had physical injuries due to falls, 119 (27.8%) were given further diagnostic tests, and 358 (83.6%) received treatment including close observation after inpatient falls. Logistic-regression results identified that age, department, and risk factors had significant impact on injuries from falls. Conclusion: Findings indicate that to reduce the severity of injury after inpatient falls, each hospital should regularly evaluate identified factors, design fall-prevention practices specialized for elders and vulnerable patients, and initiate environmental and equipment innovations.
