Purpose: This study aims to explore the distribution of work-life integration against COVID-19 and its Implications by analyzing remote work in Switzerland. Research design, data and methodology: The study performed literature review and descriptive analyses using various data such as perception surveys, statistics, and related documents. Results: The infectious disease was a turning point for many people in Switzerland by changing where and how people want to live. Since the COVID-19 crisis demonstrated that disease could be spread by proximity, negative perception about urban areas expanded, and rural areas are increasingly preferred due to fresh and clean air and a more ecological lifestyle. In addition, increased remote work, a change brought about by COVID-19, has subsequently led to changes in household habits and needs. Distance from work is no longer an important factor when someone chooses where to live. A trend is now emerging where households wanting to improve the quality of life leave the city center and move to the suburbs. Conclusions: Paradoxically, such trend accelerated by the COVID-19 crisis has an unintendedly positive impact on the distribution of work-life integration across society while providing more flexibility in terms of place and time management and lowering the burden on roads and infrastructure.

This work summarizes the current state of the art in software radio for 4G systems. Specifically, this work demonstrates that classic radio structures, e.g., heterodyne reception, homodyne reception, and their improved implementations, are inadequate selections for multi-mode reception. This opens the door to software defined radio, a novel reception architecture which promises ease in multi-band, multi-protocol design. The work presents the many advantages of such an architecture, including flexibility, reduced cost via component reduction, and improved reliability via, e.g., the elimination of environmental instability. The work also explains the limitations that currently curtail the widespread use of SDR, including issues surrounding A/D converters, management of software and power, and clock generation. This provides direction for future research to enable the broad applicability of SDR in 4G cellular and beyond.

This study aims to identify the influence of paradoxical leadership on proactive work behavior mediated through psychological safety in the hotel industry. This study employs survey data of five-star deluxe hotels in South Korea using convenience sampling. The number of 270 cases was used for analysis and the hypotheses were analyzed with structural equation modeling and AMOS 20. Paradoxical leadership includes five sub-variables of self-centeredness with other-centeredness (SO) distance and closeness (DC), uniformly and individualization (UI), work requirements and flexibility (RF), and decision control and autonomy (CA). The results indicate that DC, UI, and CA positively influence psychological safety. Further, RF and CA make a positive impact on proactive work. Psychological safety fully mediates the effect of DC and UI on proactive work behavior and partially mediates the effect of CA on it. The findings of this study suggest that the impact of paradoxical leadership on proactive work behavior can be strengthened when this relationship is accompanied with psychological safety and other mediation variables for the relationship need to be further investigated. This study suggests how hotel managers enhance the level of proactive work behavior by training themselves to be paradoxical leaders and making psychologically safe environment.

This study provides a simplified method for the evaluation of shear lag stress in rectangular box T-joints. The occurrence of shear lag phenomenon in the box T-joint generates stress concentration localized at both web-flange junctions of the beam, which leads to cracking or failure in the weld region of the joint. To prevent such critical circumstance, peak stress at the weld region is required to be checked during a preliminary design stage. In this paper, the shear lag stresses in the T-joints were evaluated using least-work solution in which the longitudinal displacements of the beam flange and web were presumed. The evaluation process considered particularly the effect of column flange flexibility, which was represented by an axial spring model, on the shear lag stress distribution. A simplified method for stress evaluation was provided to avoid solving complex mathematical problems using a stress modification factor β_s from a parametric study. The results showed that the proposed method was valid for predicting the shear lag stress in the box T-joints manually, as well compared with finite element results. The results are further summarized, discussed, and clarified that more flexible column flange caused higher stress concentration.

Purpose: The purpose of this study was to examine the effects of self stretching on shoulder pain and should flexibility of nurses. Methods: Forty two nurses who work in a university hospital participated in the study; an intervention (n=22) and a control group (n=20). The nurses of intervention group carried out a 4-week self stretching program. All participants completed 1 item NRS scale for pain intensity and 1 item 4-Likert scale for pain intensity. Both shoulder flexibilities of the nurses were measured by back and reach test. All measurements were done at baseline, 2 week, 4 week during the program and 2 week following the program. The data was analyzed by frequency, percentage, ${\chi}^2$-test, t test, Repeated measures ANOVA using SPSS 12.0. Results: There were significant differences in the pain intensity (p<.001) and frequencies(p<.001) between two groups. Also, Left and right shoulder flexibilities of the intervention group significantly increased than those of the control group (p<.001 and p=.002 respectively). Conclusion: The results showed that self stretching reduce the intensity and frequency of shoulder pain and increase both shoulder flexibilities. Thus, self stretching is recommended as an intervention to improve shoulder function of hospital nurses.

Purpose: The purpose of this study was to identify the factors affecting shiftwork tolerance among nurses and provide basic data, ultimately, in formulating a plan for improving their shiftwork tolerance. Methods: The participants were 317 nurses who were working at three general hospitals in Daejeon and Seoul. Data analyzed t-test, ANOVA, correlation analysis, and regression analysis using SPSS 20.0 program. Results: As for the sub-areas of shiftwork tolerance for the respondents, more than a half of nurses working at shifts suffered from insomnia, felt drowsy, complained of chronic fatigue, and were at the anxious and depressed state. Shiftwork tolerance differed by the daily intake of coffee and exercise. Shiftwork tolerance was significantly positively correlated with sleep-wake habits, hardiness, and flexibility and negatively correlated with a languidity. Regression analysis revealed that shiftwork tolerance was affected by age, sleep-wake habits, languidity, flexibility, and hardiness. Conclusion: To put the results, nurses had shiftwork tolerance affected by sleep-wake habits, languidity, and hardiness. It is therefore necessary to make a scheme for allowing nurses to improve hardiness and flexibility and decrease the languidity with the objective of improving their shiftwork tolerance.
