This study examined effects of attitude toward the elderly, empathy and job stress on quality of service among caregivers in long-term care facilities. The participants were 133 caregivers in C province. Data were collected from May 1 to August 31, 2019 through self reported structured questionnaire. Data analysis was performed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and stepwise regression. Empathy correlated negatively with job stress and correlated positively quality of service. Attitude toward the elderly and job stress were negatively correlated with quality of service. Job stress, empathy and attitude toward the elderly explained 31.6% of variance in quality of service among caregivers in long-term care facilities. The findings indicate that caregivers' job stress, empathy and attitude toward the elderly are important factors to be considered for the improving quality of service among caregivers in long-term care facilities.

The purpose of this study was to investigate the rheological properties of surimi gels and imitation crab-leg products by stress-relaxation test and to examine the correlations between stress-relaxation parameters and T.P.A. parameters. The linear viscoelasticity of surimi gels and imitation crab-leg products was observed in the range of the strain of $5{\sim}20%$ at cross-head speed 2.4 mm/sec. The average tensile forces of surimi gels and imitation crab-leg products were similar, 370.4 g and 436.4 g, respectively, but surimi gels showed higher relaxation time and viscous component (17256.1 sec, $1.357{\times}10^{10}$ poise) than those of imitation crab-leg products (6110 sec, $0.519^{\ast}10^{10}$ poise). Estimated tensile force of each exponential term in relaxation test was highly related with hardness, gumminess and chewiness of T.P.A (r=0.93, 0.93, 0.95, p<0.01), the relaxation time of each exponential term was rrelated with cohesiveness (r=0.89, p<0.01) of T.P,A. and the elastic component of exponential term with gumminess, chewiness and hardness (r=0.92, 0.94, 0.93. p<0.01) of T.P.A.. The viscous component of exponential term was related with cohesiveness (r=0.83, p<0.05) of T.P.A.. The degree of texturization was negatively related with the relaxation time and viscous component (r=-0.92, -0.96, p<0.01).

In order to determine creep stress intensity limit of high-temperature components, the usefulness of the creep work and time equation, defined as W$\_$c/t$\^$p/ = B(where W$\_$c/ = $\sigma$$\varepsilon$ is the total creep work done during creep, and p and B are constants), was investigated using the experimental data. For this Purpose, the creep tests for generating 1.0% strain for commercial type i16 stainless steel were conducted with different stresses; 160 MPa, 150 MPa, 145 MPa, 140 MPa and 135 MPa at 593$^{\circ}C$. The plots of log W$\_$c/ - log t showed a good linear relation up to 10$\^$5/ hr, and the results of the creep work-time relation for p, B and stress intensity values showed good agreement to those of isochronous stress-strain curves (ISSC) presented in ASME BPV NH. The relation can be simply obtained with only several short-term 1% strain data without ISSC which can be obtained by long-term creep data. Particularly, this relation is useful in estimating stress intensity limit for new and emerging class of high-temperature creeping materials.

The scaled boundary finite element method is extended to evaluate the dynamic stress intensity factors and T-stress with a numerical procedure based on the improved continued-fraction. The improved continued-fraction approach for the dynamic stiffness matrix is introduced to represent the inertial effect at high frequencies, which leads to numerically better conditioned matrices. After separating the singular stress term from other high order terms, the internal displacements can be obtained by numerical integration and no mesh refinement is needed around the crack tip. The condition numbers of coefficient matrix of the improved method are much smaller than that of the original method, which shows that the improved algorithm can obtain well-conditioned coefficient matrices, and the efficiency of the solution process and its stability can be significantly improved. Several numerical examples are presented to demonstrate the increased robustness and efficiency of the proposed method in both homogeneous and bimaterial crack problems.

Purpose: This study aimed to develop and examine the effects of a psychosocial adaptation program for North Korean adolescent defectors. Methods: This quasi-experimental study was conducted with 28 North Korean adolescent defectors who were recruited through alternative schools. The experimental and control groups consisted of 14 participants each. A program was conducted across eight sessions, each lasting about 90-120 minutes. The data were analyzed using the x² test, t-test, paired t-test, and analysis of covariance. Results: No significant differences were observed in the score changes for psychosocial adaptation (t=0.25, p=.808), post-traumatic stress symptoms (t=0.32, p=.749), cultural adaptation stress (t=0.05, p=.957), and self-efficacy (t=0.35, p=.726) in either group before and after the intervention. No intergroup differences were observed for psychosocial adaptation (t=0.12, p=.902), post-traumatic stress symptoms (t=0.07, p=.946), cultural adaptation stress (t=0.01, p=.994), and self-efficacy (t=0.58, p=.570). Conclusion: These findings suggest that psychosocial adaptation, stress, and self-efficacy cannot be improved by a short-term intervention program alone. It was also determined that the cultural characteristics of the North Korean adolescent defectors were not sufficiently considered before implementing the program. Therefore, it is essential to provide an in-depth orientation for the participants before implementing the program.

Purpose: The purpose of this study was to identify the effects of job stress, depression and fatigue on sleep quality of care workers employed in long-term care facilities. Methods: The participants were 213 care workers who worked in 11 long-term care facilities. The collected data was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple linear regression with using the SPSS 23.0 program. Results: We found that patient-related job stress was the greatest stressor among care workers' job stresses. A significant difference in sleep quality was observed according to the self-perceived health status of the care workers. The care workers' sleep quality was negatively correlated with job stress (r=-.16, p=.018), depression (r=-.31, p<.001) and fatigue (r=-.29, p<.001). The influencing factors of sleep quality were depression (${\beta}=-0.22$, p=.001) and fatigue (${\beta}=-0.15$, p=.047). Conclusion: It is necessary to improve the health status and sleep quality of care workers by developing and applying health promotion programs to reduce the depression and fatigue of the care worker. This will ultimately improve the quality of service care for the patients.

Purpose: This study aimed to identify the mediating effect of Psychological stress of COVID-19 stress on the relationship between nursing work environment and turnover intention of nurses in long-term care hospitals. Methods: The participants were 176 nurses working at three long-term care hospitals in Changwon City. Data were collected from August 11 to 14, 2021, using self-report questionnaires. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression, using the SPSS 23.0 software. A mediation analysis was performed according to the Baron and Kenny's test, and Sobel test. Results: Turnover intention was positively correlated with Psychological stress of COVID-19 stress (r=.23, p=.002) and negatively correlated with nursing work environment (r=-.44, p<.001). Psychological stress of COVID-19 stress had a significantly negative relationship with nursing work environment (r=-.15, p=.045). Psychological stress of COVID-19 stress partially mediated the relationship between nursing work environment and turnover intention. Conclusion: The findings of this study indicate that a positive nursing work environment can help nurses reduce their Psychological stress of COVID-19 stress and turnover intention. To reduce the turnover intention among nurses' in long-term care, it is necessary to promote better work environments suitable for COVID-19 and to establish detailed strategies for reducing their physiological stress.

This study aimed to compare job stress and job satisfaction of long-term care staffs caring for demented seniors with rating 3 and physically disabled seniors with rating 1. Survey was conducted upon 212 long-term care staffs in long-term care institutions in Ejungboo, Goyang, and Paju. There were, first of all, statistically significant differences between those groups in the level of overall stress, stress related to service subjects, and stress in service procedures. Regression analyses, secondly, showed that the relationship between job stress and job satisfaction was statistically significant only for long-term care staffs for demented seniors with rating 3. The results suggest that it is necessary to lower the level of stress especially for the staffs caring for demented seniors with rating 3. Furthermore, we need to consider the stress, that the staffs feels in the process of caring for long-term care service beneficiaries, as a important variable for intervention programs to reduce the level of stress among long-term care staffs.

A novel and simple method using a cylindrical penetrometer is being developed for the measurement of yield stress. The principle of this technique is based on the measurement of the static equilibrium of a falling penetrometer in a yield stress fluid. The yield stress is simply determined by a balance of forces acting on the penetrometer. The yield stress of Carbopol gels and $TiO_2$ suspensions has been measured using this method. The results are in reasonable agreement with the values from conventional methods. The effects of the dimensions and weight of the penetrometer have been examined. The long-term behaviour was also observed. No measurable creep was seen and equilibrium was found to be very quickly established. The cylindrical penetrometer technique promises to be a simple, quick and reliable static method for the measurement of yield stress.
