This study is a descriptive research on the subjects of hospital nurses to investigate the effect of job satisfaction and fatigue on their nursing professional attitudes. The subjects were 262 nurses working at five general hospitals in J and S cities. Data collection was conducted from December 2014 to January 2015 using structured questionnaires on job satisfaction, fatigue and nursing professional attitudes. As a result of the study, nurses' nursing profession attitude was high in 30 year old and married nurses, and in clinical experience of either less than a year or more than six years, and nurses' nursing profession attitude was higher in charge nurses and head nurses than in general nurses. The most influential factors affecting the nursing professional attitude were job satisfaction, clinical career, and fatigue in that order. These findings provide theoretical evidence to explain the importance of job satisfaction and fatigue variables in influencing factors on nursing professional attitude. Therefore, in clinical practice, it is necessary to develop and implement an education program to improve nursing professional attitudes by considering nurses' job satisfaction, clinical career and fatigue level.

The fatigue characteristics of glass fiber reinforced plastic (GFRP) composites were studied under repeated loads using the finite element method (FEM). To realize the material characteristics of GFRP composites, Digimat, a mean-field homogenization tool, was employed. Additionally, the micro-structures and material models of GFRP composites were defined with it to predict the fatigue behavior of composites more realistically. Specifically, the fatigue characteristics of polybutylene terephthalate with short fiber fractions of 30wt% were investigated with respect to fiber orientation, stress ratio, and thickness. The injection analysis was conducted using Moldflow software to obtain the information on fiber orientations. It was mapped over FEM concerned with fatigue specimens. LS-DYNA, a typical finite element commercial software, was used in the coupled analysis of Digimat to calculate the stress amplitude of composites. FEMFAT software consisting of various numerical material models was used to predict the fatigue life. The results of coupled analysis of linear and nonlinear material models of Digimat were analyzed to identify the fatigue characteristics of GFRP composites using FEMFAT. Neuber's rule was applied to the linear material model to analyze the fatigue behavior in LCF regimen. Additionally, to evaluate the morphological and mechanical structure of GFRP composites, the coupled and fatigue analysis were conducted in terms of thickness.

The significance of pilots' fatigue and the attributed risk management had continuously increased over time as the airline industry expanded. Research and legislation efforts associated with pilot fatigue are being taking place actively all over the world. In the developed world such as the United States and European Union etc., the airline pilot fatigue is already being managed by considering the show up time, the number of take offs and landings made, resting period, jet lag etc., when computing flight duty time. In Korea, the flight duty time is only limited by the total number of hours per given period regardless of the flight conditions and environment. Such lack of regulation demand development of a fatigue management program. According to the survey taken from the airline pilots in Korea, it has been found that acquiring foreign policies directly may in turn, increase the risk of fatigue. This research suggest future studies regarding fatigue management program adapted exclusively to Korean domestic flight environment and culture.
