While prior work has conducted individuals' password security behavior, there is a relatively neglect to examine individuals' affect and feelings of password fatigue in password change context. Therefore, this study explicated individuals' affective response to the feelings of password fatigue by drawing on several theoretical lens. Survey data collected from 267 users were used to test the model using partial least square analysis. This study found that feelings of password fatigue positively affected the negative password fatigue-induced affect, and also both the feelings of password fatigue and the negative password fatigue-induced affect were negatively related to attitude toward changing passwords, which in turn, leads to the intention to change passwords. Furthermore, this study found that shadow work recognition negatively moderated the relationship between attitude and behavioral intention. This study could offer a new theoretical perspective to understand an individual's security behavior and provide empirical evidences for practitioners in charge of IT security in organizations.

For gas turbine engines, the safe life methodology has historically been used fur fatigue life management of failure critical engine components. The safe retirement limit is necessarily determined by a conservative life evaluation procedure, thereby many components which have a long residual life are discarded. The objective of this study is to introduce the damage tolerant design concept into the life management for aircraft engine component instead of conservative fatigue life methodology which has been used for both design and maintenance. Crack growth data were collected on a nickel base superalloy which have been subjected to combined static and cyclic loading at elevated temperatures. Stress analysis fur turbine disk was carried out. The program for computing creep-fatigue crack growth was developed. The residual lifes of turbine disk component under various temperatures and conditions using creep-fatigue crack growth data were estimated. As the result of analysis, it was confirmed that retirement fur cause concept was applicable to the evaluation of residual life of retired turbine disk which had been designed based on the conventional fatigue life methodology.

In this paper, static and fatigue load tests for the specimens, components and carbody were carried out to investigate the strength of welded joints in aluminum rolling stock. Tensile load test results showed that the static strength of welded joint for heat-treated alloys is reduced significantly and fatigue strengths are scattered by the welding imperfections. Component and whole carbody fatigue test results showed agreements with the design fatigue strength standards for specimens of same joint detail. Test results revealed that full penetration welding and strict management of welding procedure are crucial for securing strength of welded joint in aluminum carbody.

Tyrosine kinase inhibitor is known to prolong progression free survival in radioiodine refractory thyroid cancer patients. Fatigue/asthenia/malaise is one of most common adverse events by the tyrosine kinase inhibitor treatment, and management of the adverse event is important to keep the drug medication longer which is essential for the survival benefit. In the case report, a radioiodine refractory thyroid cancer patient receiving tyrosine kinase inhibitor experienced severe fatigue, and a pathologic fracture of right humerus occurred by slipping down which was tightly linked with the adverse event of the drug. The pathologic fracture was surgically well managed and the adverse event was well controlled by supportive managements combined with dose reduction of the tyrosine kinase inhibitor. The drug administration to the patient was kept more than 1 year without progression of the disease.

Purpose: In this study the literature of compassion fatigue in nurses was reviewed in order to analyze the trends of overall research for level of fatigue, symptoms, and factors. Methods: For this study, five databases were searched using the key words 'compassion fatigue', 'secondary traumatization', 'secondary traumatic stress', and 'vicarious traumatization'. Thirty-six papers were analyzed. Results: Most of the compassion fatigue research (86%) was conducted between 2006 and 2011 and the most frequent research approach was quantitative research with the ProQOL which was the most frequently used instrument in the studies. He research was conducted in pediatric, emergency & trauma, oncology, psychiatric, and hospice units with no consistent patterns of t compassion fatigue levels. Factors affecting compassion fatigue were personal factors such as age, education background, work-related factors such as caring for trauma patients, work hours, psychological factors such as work stress, burnout, and support/coping factors such as organizational support, and coping resources. Conclusion: Nurses' compassion fatigue varied from low to high by nursing specialties. Many factors affected the compassion fatigue of nurses. In the future there is a need for study on Korean nurses, and identification of groups at risk for compassion fatigue. Furthermore there is a need to develop management programs on compassion fatigue in nurses, stress reduction and wellbeing.

Mental fatigue is inevitable in the workplace. Since mental fatigue can lead to decreased efficiency and critical accidents, it is important to manage mental fatigue from the viewpoint of accident prevention. An experiment was performed to evaluate mental fatigue using the formant frequency analysis of human voices. The experimental task was to mentally add or subtract two one-digit numbers. After completing the tasks with four different levels of mental fatigue, subjects were asked to read Korean vowels and their voices were recorded. Five vowel sounds of "아", "어", "오", "우", and "이" from the voice recorded were then used to extract formant 1 frequency. Results of separate ANOVAs showed significant main effects of mental fatigue on formant 1 frequencies of all five vowels concerned. However, post-hoc comparisons revealed that formant 1 frequencies of "아" and "어" were most sensitive to mental fatigue level employed in this experiment. Formant 1 frequencies of "아" and "어" significantly decrease as the mental fatigue accumulates. The formant frequency extracted from human voice would be potentially applicable for detecting mental fatigue induced during industrial tasks.

Background: Mine workers in South Africa face challenges relating to poor health and safety, including fatigue risks, and poor socioeconomic and living conditions. Fatigue results in impaired mental and physical performance. The aim of this study was to assess contributors to fatigue of mine workers in South Africa. Methods: Data collection took place at four gold mines and one platinum mine in South Africa. A total of 21 focus groups were held with individuals in management, union representatives, and mine workers, and 564 questionnaires were completed by mine workers to gather information about fatigue and potential contributors to fatigue at these mines. Results: Qualitatively (through focus groups), fatigue was attributed to extended working hours, harsh working conditions, high workloads, production pressure, and resource constraints, along with aspects relating to demographic and socioeconomic factors, living conditions, lifestyle, health, and wellness. Greater fatigue was significantly associated with younger age, indebtedness, a lack of exercise, poor nutrition, less sleep, increased alcohol use, poor self-reported health, more sick leave, higher stress, and lower job satisfaction. Conclusion: The aim of the study was achieved; numerous work-, sociodemographic-, lifestyle-, and wellness-related factors were linked to fatigue in the participating mine workers. Contributors to fatigue should be addressed to improve health, safety, and sustainability in the industry.
