Purpose: This study was conducted to identify the relationships between the perceived and actual achievement on skill performance assessment and identify the relation to learning motivation factors. Methods: A total of 80 senior nursing students currently studying at a university participated in the study in 2015. Students completed a performance examination of 20 nursing skills at the end of their 7-week training period; their performance was rated using checklists. Students then completed a survey, which included questions about learning motivation and perceived achievement level. Data were analyzed by descriptive statistics, Pearson's correlation, and Kruskal-Wallis test. Results: There was a weak correlation between perceived and actual achievement. Intrinsic and extrinsic goal-orientation and self-efficacy in learning motivation factors was significantly correlated to perceived achievement. Perceived achievement and self-efficacy in middle quartile of actual achievement were higher than other upper- or lower-quartile group. Conclusion: The findings suggest that the motivation factors of learners should be taken into account to maximize academic achievement in nursing skills training. In addition, it should be considered a strategy to reduce the gap between perceived and actual achievement.

During the initial design phases for prestressed concrete structures, the mecessary information concerning the physical properties of the hardened concrete such as creep, drying shrinkage, modulus of elasticity, and Poisson's ratio are obtained from design assumptions or accepted standards. But these assumptions may not totally reflect the actual long-term behavior of the concrete. So they may be of limited use in predicting the actual behavior. The purpose of this paper is to describe the test procedures and methods of evaluation which were used during the long-term study.

When a modeling process is applied to an actual commodity market in the real world, interactions over closely related commodities through the marketing channel should also be formulated into the model to reflect the information that exists in the whole market system, otherwise unreliable estimates and test statistics may be produced by ignoring those effects. Single-equation type model in this case tends to yield inefficient estimates, and sometimes biased and inconsistent, which will mislead us. A system of equation method to examine the structure of the imported commodity market system is developed and its emtirical results are analyzed, then followed by some policy experiments and its implications.

As railway trains run faster high performance braking system are necessary because more energy needs to be dissipated due to increased kinetic energy. In this work a portable computer based prediction system for emergency braking distance has been developed. The algorithm for the system is based on braking theory and empirical results of actual braking test. The computer is connected to the sensors to measure the velocity and the braking pressure in real train. It is expected that this system will be utilized to predict emergency braking distance during actual operation of the train

The effectiveness of an actual combat tank system is analyzed. A measure of effectiveness which includes performance and reliability called pseudo-reliability is introduced. A model is introduced to optimize the design of the system in which the system pseudo-reliability is maximized subject to cost constraint. This model is a nonlinear programming problem and is solved by the sequential unconstrained minimization technique (SUMT). A numerical exampl with actual data from the test evaluation of five combat tanks is used to illustrate the model.

Underground flexible pipes for electric cables are subject to external loads and surrounding soil pressure. Particularly, strain of flexible pipes is of great concern in terms of safety and maintenance for electric cables. In this study, the actual size tests were carried out to investigate strain-deformation relation for underground flexible pipes subject to vehicle loads with various depths and degree of compaction.

Characterization tests (load vs. displacement curve) are conducted for the springs of Zirconium alloy spacer grids for an advanced LWR fuel assembly. Twofold testing is employed: strap-based and assembly-based tests. The assembly-based test satisfies the in situ boundary conditions of the spring within the grid assembly. The aim of the characterization test via the aforementioned two methods is to establish an appropriate assembly-based test method that fulfills the actual boundary conditions. A characterization test under the spacer grid assembly boundary condition is also conducted to investigate the actual behavior of the spring in the core. The stiffness of the characteristic curve is smaller than that of the strap-wised boundary condition. This phenomenon may cause the strap slit condition. A spacer grid consists of horizontal and vertical straps. The strap slit positions are differentiated from each other. They affords examination of the variation of the external load distribution in the grid spring. Localized legions of high stress and their values are analyzed, as they may be affected by the spring shape. Through a comparison of the results of the test and FE analysis, it is concluded that the present assembly-based analysis model and procedure are reasonably well conducted and can be used for spring characterization in the core. Guidelines for improving the mechanical integrity of the spring are also discussed.

This paper presented a actual conditions on a false-tripping of ELB(Electrical Leakage Breaker) and an assessment of the harmonics due to non-linear electronic equipment such as personal computers, printers, fax machines, and test equipments in several office buildings. Actual conditions on a failure of ELB were surveyed and analyzed by making up a question to safety managers of in office buildings. Also, power quality measurements such as harmonic currents, voltage and current waveforms and current imbalance were made at various office buildings where nuisance tripping of ELB is often occurred. The results of this study can be used in making decisions regarding cause of ELB trip and operating md tripping characteristics test of ELB when subjected to distorted current waveforms.
