The purpose of this study is to understand verbal violence and stress experienced by nurses, to identify measures to reduce such stress, and to present basic information needed for performing their professional roles. The results of this study are as follows. First the types of verbal violence by doctors, nurses, patients and their caregivers included "they speak roughly" and "they speak in a commanding tone" when they were marked on the basis of 5 points. In other words, speaking roughly is highest in frequency. Second, the main harmers of verbal violence were doctors, nurses, and patients and their caregivers, and thus verbal violence by nurses was most frequent. Third, the emotional reactions of the nurses after verbal violence were "angry", "frustrated", and "depressed" in order. As a result of analysis of effects on the emotional reactions of nurses. Fourth, the job stress of the nurses after experience of verbal violence was show as "frequently struggling with friends", "frequently struggling with family members", and "frequently drinking" in order. Fifth, based on general characteristics, the emotional reactions and job stress of nurses after verbal violence were significant on age, acdemic years, and current workplace, and the job stress of nurses after verbal violence was significant on marriage, clinical career, department of working, and types of working. This study may be significant in that it suggests methods of intervention, safe job environment, and administrative institution to relieve the emotional reactions of nurses after verbal violence, to reduce their stress, and to support the emotional reactions of nurses experienced verbal violence.

Purpose: The study aimed to identify the stress levels and their solutions in MZ(Millennials + generation Z) nursing students by using photovoice through the medium of photography. Methods: The study was conducted from November to December 2022 among freshmen to senior nursing students at a major university. Participants were recruited by telephone, email, and social media. Originally, four participants were recruited for each year of nursing school, but it resulted in a total of 19 participants: three freshmen students, nine sophomore students, four junior students, and three senior students. The participants were asked to take pictures of things in their surroundings that bothered them and things that helped them overcome the bothering things and to have group discussions in groups of 4-5 to analyze the results. Results: The results of the study revealed the following themes: 'Difficulties and worries as a nursing student', 'Striving to go beyond yourself', 'Unhealthy factors', 'Ways to relieve stress', and 'Meaning of stress'. For each of the themes, there were five subcategories under 'difficulties and worries as a nursing student', four under 'fighting with oneself', seven under 'ways to relieve stress', five under 'unhealthy factors', and two under 'meaning of stress', resulting in 21 subcategories. Conclusion: Based on the results of the study, firstly, there is a need to educate university students about the factors that contribute to unhealthy behaviors and how to deal with stress in a healthy way. Secondly, it is necessary to provide programs that allow students to have various experiences.

This paper deals with the residual stresses developed in an epoxy film deposited on Si wafer. First, chemically induced residual stresses due to the volumetric shrinkage in cross-linking resins during polymerization are treated. The curvature measurement method is employed to investigate the residual stresses. Then, thermally induced stresses are investigated along the interface between the epoxy film and Si wafer. The boundary element method is employed to investigate the whole stresses in the film. The singular stress is observed near the interface corner. Such residual stresses are large enough to initiate interface delamination to relieve the residual stresses.

Finite element analysis was carried out to investigate the integrity and reliability of boiler module during sea transportation. The boiler module was supported by steel structure to relieve the instantaneous shock from oceanic wave and its primary parts were strengthened with several reinforcements. Finned tube walls which were used in the furnace wall were assumed as orthotropic plates having equivalent material properties. The bank tubes were also equivalently modeled in accordance with ASME B31.1 for the convenience of finite element modeling. The calculation results were compared with the yield stress of the material. In particular, the bank tube stress, which was evaluated by converting the calculated stresses in equivalent tubes into those in original tubes by using the ratio of diameter, was also examined with yield stress.

One of the most interesting and promising steel groups considered for the rocket motor case, aircraft and aerospace component is the maraging(martensitic plus aging) nickel steel, developed by International Nickel Company in 1960. This material attains a very high strength with good fracture toughness by simple heat treatments which do not involve a quenching. Full strength can be obtained by "maraging" at 480.deg. for 3 hours for the 18% Ni maraging steel. The effect of heat treatments was considered on the residual stress field of 18% Ni maraging steel weldments. In experiments, various heat treatments such as stress relieve heat treatment, aging and solution heat treatment were carried out of the GTA weldments and the residual stresses were measured by using the hole drilling method. Whereas the conventional pattern of residual stress shows the stresses to be maximum along the weld centerline with tensile stress extending into the heat affected zone, the pattern in maraging steels shows the centerline stress to be compressive. After welding, a series of aging, solution heat treatment and solution heat treatment plus aging treatment were carried out and the residual stresses were measured to reveal that these heat treatments almost completely remove the welding residual stresses.
