This study examined whether there are differences in health knowledge, health behavior, and health education teaching efficacy according to the general characteristics of pre-service early childhood teachers and analyzed the relationship between each variable to identify the factors affecting the teaching efficacy. For these, health knowledge, health behavior, and health education teaching efficacy were measured for 258 students enrolled in the department of early childhood education in colleges located in Chungnam and Jeonbuk. The collected data were subjected to a t-test, Welch variance analysis, correlation analysis, and multiple regression analysis using SPSS Win 21.0 according to the research problem. The results were as follows. First, there were significant differences in health knowledge, health behavior, and health education teaching efficacy, according to some of the general characteristics of the subjects. Second, while there was a significant positive correlation between the overall and subordinate variables of health behavior and teaching efficacy, there was a marginally significant correlation between health knowledge and teaching efficacy. The variable affecting health education teaching efficacy was the overall health behavior, and the explanatory power was approximately 30%. Suggestions for subsequent research were proposed based on the above research results.

This study examined factors affecting the stages of exercise behavior among patients with rheumatoid arthritis. The analysis was based on data collected from 238 patients who enrolled at the medical center of D university. The participants showed 5 stages of exercise behavior: pre-contemplation 23.9%, contemplation 23.0%, preparation 33.2%, action 5.0%, and maintenance 29.0%. There were statistically significant differences in perceived barriers of exercise, exercise self-efficacy, and perceived health status according to the stage of exercise behavior of the subjects. It was found that among the barriers to exercise, physical and cognitive psychological factors significantly influenced the stages of exercise behavior. Also, exercise self-efficacy significantly affected the stages of exercise behavior. Thus, for rheumatoid arthritis patients to practice and maintain proper exercise behavior, the nursing staff should continue to assess and reduce the barriers to exercise. Exercise programs should enhance self-efficacy to achieve long-term exercise behavior.

What was once known as common courtesy is rapidly disappearing in the air travel industry, and the violent behavior known as air rage is a constant threat. Once sought after by other industries for advice because of its expertise in customer service, the air travel industry has now slipped to the lowest rungs of companies with unhappy customers. As airlines cut corners in order to avoid bankruptcy, passengers' patience is tested by the stress of flight delays, crowded airports and close packed seating on airplanes. This article examines the situation, strategies used by passengers and ways the airline industry might better inspire courteous behavior in passengers. A cultural expectation of entitlement and competitiveness for limited resources has led to a breakdown in civilized behavior throughout society, both in the United States and internationally. Air travelers faced with rude and intrusive behavior from others on the flight are beginning to find their own ways of coping, such as high quality headphones to block offensive noises, and mechanical devices to keep the seat in front from reclining to the point where it hits their knees. The most potentially effective remedies will come from airlines that enlist cooperation by offering effective passenger education and possibly even incentives. Acceptable airline behaviors need to be plainly defined and stressed for passengers, both before boarding and onboard. In this paper, some methods are suggested to motivate passengers and to inspire courteous behavior.

The purpose of this study is to investigate experimentally the effects of both seismic loading and crack length on the fracture behavior of piping system with a circumferential crack in nuclear power plants. The experiments were performed using both large scale piping system facility and 4 points bending test machine under PWR operating conditions. The difference in the load carrying capacities between cracked piping and non-cracked piping was also investigated using the results from experiments and numerical calculations. The results obtained from the experiments and estimation are as follows : (1) The safety margin under seismic loading is larger than those under quasi static loading or simple cyclic loading. (2) There was no significant effect of crack length on tincture behavior of piping system with both a surface crack and a through-wall crack. (3) The load carrying capacity in cracked piping was reduced by factors of 7 to 46 compared to non-cracked piping.

Purpose: This study was to develop nursing competencies, sub-competencies and behavior indicators according to the clinical ladder of emergency nurses. Method: index of content validation was used by 21 clinical experts. Results: This study had three phases to develop nursing competencies, sub-competencies and behavior indicators. In first phase: 12 nursing competencies and 33 sub-competencies were developed through the literature review on nursing competency and emergency nurses' job description. The content of 12 competencies and 33 sub-competencies were reviewed by 3 nursing professors. The 12 competencies and 33 sub-competencies were followed: clinical judgement and measures(6 sub-competencies), processing ability of ward works(2 sub-competencies), flexibility(2 sub-competencies), resources management(2 sub-competencies), confidence(3 sub-competencies), cooperation(2 sub-competencies), professional development power(2 sub-competencies), patient service orientation(3 sub-competencies), inclination toward ethical value(5 sub-competencies), influence power(2 sub-competencies), developing others(2 sub-competencies), self control(2 sub-competencies). In second phase, 132 behavior indicators were developed according to nurse clinical ladder: novice, advanced novice, competent, proficient. In Third phase, content validity was examined on 132 behavior indicators by 21 clinical experts. 126 among 132 indicators had over 70% agreement among experts and 6 indicators under 70% were revised. Conclusion: nursing competencies, sub competencies and behavior indicators can be used nurses' clinical performance as well as establishing proper directions for professional growth related to reward system.

The microstructure of highly aggregated colloidal dispersions was investigated by probing the rheological behavior of magnetic suspensions. The dynamic moduli as functions of frequency and strain amplitude are shown to closely resemble that of colloidal gels indicating the formation of network structure. The two types of characteristic critical strain amplitudes, γ_c and γ_y, were characterized in terms of the changing microstructure. The amplitude of γ_c indicates the transition from linear to nonlinear viscoelasticity and depends only on particle volume fraction not magnetic interactions. The study of scaling behavior suggests that it is related to the breakage of interfloc, i.e., floc-floc structure. However, yielding strain, γ_y, was found to be independent of particle volume fraction as well as magnetic interaction. It relates to extensive deformation resulting in yielding behavior. The scaling of elastic constant, G_e, implies that this yielding behavior and hence γ_y is due to the breakage of long-range interfloc interactions. Also, the deformation of flocs due to increase strain was indicated from the investigation of the fractal nature.

A modular fish-bone girder pier consists of one main girder system named as "Spine Girder". Therefore, this pier can be most affected by torsion as well as flexural bending. The design considerations of the fish-bone girder pier are proposed to assure the reasonable design in this study. In order to investigate the behavior characteristics, structural analysis F.E model is developed, and the verification of the developed model is performed by comparison with experimental data. From the investigation of the structural behavior, the vertical stiffener is required at the bottom of bone-beams to prevent the excessive local stress. Also, it is found that the normal stress of the flange and the shear stress of the web and flange are dominantly affected by the warping torsion and pure torsion, respectively.

Although friction pendulum system has various advantages it is difficult to estimate the behavior because of velocity, bearing pressure, and temperature dependent characteristics of coefficient of friction. This research focuses on evaluating the conservatism of each method used and the effects of bearing pressure on the behavior of the system by conducting comprehensive examination on design and analytic procedure of friction pendulum system, as is proposed in standard, code and literature. In addition, this study provides comparative analysis on general behavior characteristics of friction pendulum system by comparing the result with that of the analysis on lead rubber bearing which possesses the same dynamic properties.
