Objectives: The purpose of this study is to understand the effect of infection anxiety about COVID-19 perceived by home appliance installers and repair technicians on work stress. Methods: To collect data, the purpose of the study was explained through the labor union of domestic home appliance service companies, and a survey was conducted through mobile to 286 home appliance installers and repair technicians who agreed to the survey. Results: As a result of the analysis, it was found that age, fatigue, work satisfaction, visit time, and Corona 19 infection anxiety had a significant effect on work stress. In other words, the higher the age, the higher the fatigue, the lower the job satisfaction, the higher the work stress was when the visit time was more than 30 minutes, and the higher the Corona 19 infection anxiety, the higher the work stress. Conclusions: Based on the results of this study, the following suggestions are made. First, in order to prevent work stress, we propose the development of a workplace health care program that can solve fatigue. Second, it is necessary to prepare a working environment and provide institutional support to reduce work stress by increasing Job satisfaction. Third, a workplace quarantine measures is needed to prevent infection for essential-workers who do face-to-face work in preparation for possible infectious diseases in the future.

Purpose: This qualitative study utilizing phenomenological methodology aimed to depict parental measles mumps rubella (MMR) vaccine acceptance through the work experiences of health personnel. Materials and Methods: Twenty-two public health workers working as vaccination providers in the three southern border provinces of Thailand were recruited. In-depth, face-to-face, semi-structured interviews were conducted. Data were analyzed using thematic analysis. Results: Four main themes emerged: (1) religious beliefs, (2) personal disagreements, (3) fear and mistrust regarding potential vaccine side effects, and (4) misperceptions about the potential severity of measles. Four subthemes were identified: (1) haram (prohibited), (2) the will of Allah, (3) spousal disagreement, and (4) disagreement from a religious leader. The results of this study indicated that perceived religious prohibition was the most important reason for refusing to vaccinate among Muslim parents. Vaccine-hesitant parents were concerned that the vaccine might contain gelatin derived from pig products. Also, halal certification of the vaccine was required from Muslim parents to ensure that vaccine has been approved for Muslims. Meanwhile, a lack of knowledge and positive attitudes concerning immunizations of vaccine-hesitant parents were also found as predominant reasons for incomplete childhood immunizations in the deep south of Thailand. Conclusion: Health education and engagement by religious leaders to endorse the vaccination and bridge the gap between religious beliefs and vaccine acceptance is needed to overcome this issue. This study findings could be effectively applied to improve vaccination uptake in a Muslim majority context.

After COVID-19, team's collaborations are conducted online using whiteboard tools as remote working increases. In order to understand the problems of the convergence process using online whiteboard tools, an observation study comparing online and offline collaboration and a focus group interview were conducted. In addition, a questionnaire was conducted to confirm the found problem, and a solution idea was proposed. through in-depth interviews, we validate the proposed ideas. The convergence process of collaboration using online whiteboard tools had problems ; "excessive amount of information", "shift of view", "role of facilitator". To solve the problems, we proposed the idea of classifying each stage of the collaboration process, providing a navigator, and facilitator request system window. This paper proposed an idea that can effectively help the convergence process directly related to decision-making during the online collaboration process through analysis of advantages and problems of online and offline collaboration.

In 2020, the novel coronavirus disease (COVID-19) struck the world. This study examined Korean public libraries' responses during the COVID-19 pandemic to determine their working practices, service patterns, applied strategies, and roles played. The study administered an online survey to 317 public librarians in South Korea. The results indicated that librarians reported significant transitions regarding the services provided. However, only 15.5% of the survey respondents reported that they had experienced trainings/workshops for library staff members. Survey participants also identified challenges such as the limitations of non-face-to-face services, complaints from library patrons, and overwork due to epidemic prevention. When it comes to the expected roles of public libraries in upcoming disasters, the study contends that information providers, who guide the public through various information resources, would play the most critical role. An analysis of a few open-ended questions' answers proliferated the highlighted findings. Based on the key findings, this paper also discussed implications for information professionals and future research.

Objectives: This study investigated the need for nutrition education aimed at improving the health of residents and users of social welfare facilities for persons with disability and aimed to provide basic information for developing a nutrition education program that meets the needs of the field. Methods: Altogether, 249 employees working in social welfare facilities for people with disabilities were included in the study. Data on the health status of residents/users, meal management, nutritional education, nutritional education needs, and awareness of nutritional education were obtained through online surveys. A descriptive analysis was conducted to analyze the demographic characteristics, needs, and perceptions of the respondents, and independent t-tests and χ² tests were performed to analyze and compare the differences between residential and daycare facilities. Results: The majority of residents/users of social welfare facilities for persons with disabilities have developmental disabilities. When educating residents with residents/users of social welfare facilities, 'personal hygiene' was the most necessary topic, followed by 'obesity management' education. Regarding the methods of providing education, face-to-face lectures demonstrated a high demand. They responded that when nutrition education experts provide nutrition education to people with disabilities, they must understand 'the physical characteristics of persons with disabilities' and have the ability to determine appropriate nutrition for such people. The most appropriate nutrition program training would be twice a year, lasting 30 min to 1 h per training session. Conclusions: It will present a direction for operating a nutrition education program for persons with disabilities that meets their needs of social welfare facilities and ultimately contribute to the establishment and activation of nutrition education tailored to welfare facilities for such individuals in Korea.

The process of inspecting and replacing cutting tools in a shield tunnel boring machine (TBM) is called cutterhead intervention (CHI) (Farrokh and Kim 2018). Since CHI is performed by a worker who enters the chamber in TBM, the worker is directly exposed to high water pressure and huge water inflow, especially in areas with high ground water levels, causing health problems for the worker and shortening of available working hours (Kindwall 1990). Ham et al. (2022) proposed a method of reducing the water pressure and water inflow by injecting a grout solution into the ground through the shield TBM chamber, and named it the new face grouting method (NFGM). In this study, the TBM mechanical characteristics including the injection pressure of the grout solution and the cutterhead rotation speed were determined for the best performance of the NFGM. To find the appropriate injection pressure, the water inflow volume according to the injection pressure change was measured by using a water inflow test apparatus. A model torque test apparatus was manufactured to find the appropriate cutterhead rotation speed by investigating the change in the status of the grout solution according to the rotation speed change. In addition, to prove the validity of this study, comprehensive water inflow tests were carried out. The results of the tests showed that the injection pressure equal to overburden pressure + (0.10 ~ 0.15) MPa and the cutterhead rotation speed of 0.8 to 1.0 RPM are the most appropriate. In the actual construction site, it is recommended to select an appropriate value within the proposed range while considering the economic feasibility and workability.

Purpose: This study aimed to determine the influence of psychological factors such as highly sensitive person, intolerance of uncertainty, depression, and self-esteem on nurses' perceptions of gaslighting damage. Methods: The participants were 178 nurses working in hospitals nationwide. Data were collected through a non-face-to-face approach using an online survey platform (Google Forms) with self-reported questionnaires. Perceptions of gaslighting damage were measured using the victim gaslighting questionnaire (VGQ). The collected data were analyzed with statistical methods such as independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis using IBM SPSS 25.0. Results: Of the participants, 94.4% were female. The participants' average age was 32.7 years old, 60.2% were unmarried, and 86.0% were staff nurses. The mean score of the VGQ was 40.49. There were statistically significant differences in the VGQ according to marital status, participants' time in their current department, total clinical career, and type of medical institution. The perception of gaslighting damage was statistically significantly positively correlated with intolerance of uncertainty, highly sensitive person, depression, and self-esteem. The most influential factor on nurses' perception of gaslighting damage was intolerance of uncertainty (β=.32, p<.001), followed by depression (β=.30, p<.001) and highly sensitive person (β=.23, p=.001). The total explanation of these variables for the perception of gaslighting damage by nurses was about 75.0%. Conclusion: This study suggests that it is necessary to develop an intervention program to reduce negative psychological factors affecting gaslighting in nurses and to cultivate nurses' strength to overcome gaslighting damage.

The appropriate interpretation of social cues is a crucial ability for everyday life. While processing socially relevant information, beyond the low-level physical features of the stimuli to emotional information is known to influence human cognition in various stages, from early perception to later high-level cognition, such as working memory (WM). However, it remains unclear how the influence of each type of emotional information on cognitive processes changes in response to what has occurred in the processing stage. Past studies have largely adopted face stimuli to address this type of research question, but we used a unique class of socially relevant motion stimuli, called biological motion (BM), which depicts various human actions and emotions with moving dots to exhibit the effects of anger, happiness, and neutral emotion on task performance in perceptual and working memory. In this study, participants determined whether two BM stimuli, sequentially presented with a delay between them (WM task) or one immediately after the other (perceptual task), were identical. The perceptual task showed that discrimination accuracies for emotional stimuli (i.e., angry and happy) were lower than those for neutral stimuli, implying that emotional information has a negative impact on early perceptual processes. Alternatively, the results of the WM task showed that the accuracy drop as the interstimulus interval increased was actually lower in emotional BM conditions than in the neutral condition, which suggests that emotional information benefited maintenance. Moreover, anger and happiness had distinct impacts on the performance of perception and WM. Our findings have significance as we provide evidence for the interaction of type of emotion and information-processing stage.

The air quality near the backfilled site area is significantly deteriorated during and even after the curing period of the backfill materials. Hazardous gases such as NH3 and CO2 may leak out prolongedly from the mined-out sites backfilled with the composite carbonate-based material; leakage can be observed at the underground working sites as well as on the surface. At operating mines, underground gas leakage will severely aggravate the workplace environment. The ventilation schemes should supply sufficient air to dilute the contaminated air, and control the toxic gas leakage and dispersion. This study shows the applicability of pressurization ventilation system to control gas leakage and dispersion at the backfilled underground mine site.
