The purpose of this study was to identify perceived work-family conflict of married working women and men with children under 12 years. Specifically, This study attempts to examine the differences of relative influence between objective time variables and subjective satisfaction variables unlike previous research. For research, this study used the data of 1012 working men and women from the 3rd Nation survey of Korean Family in 2015. The main results of this study were as following. First, Business hours and cognition of enough leisure time had more relative effect of work${\rightarrow}$family conflict than any other variable. On the other hand, leisure time on weekdays had the effect of family${\rightarrow}$work conflict with women and men. Second, gender differences of work${\rightarrow}$family conflict and family${\rightarrow}$work conflict were identified. In work${\rightarrow}$family conflict, men were influenced cognition of enough leisure time, women were influenced couple conversation time and employment status unlike men. In family${\rightarrow}$work conflict, men were not influenced subjective satisfaction variables. But women were influenced satisfaction with division of child care. Third, in family${\rightarrow}$work conflict, the addition of objective time variables in Model of men resulted in an increased $R^2$-value, but in work${\rightarrow}$family conflict and family${\rightarrow}$work conflict, the addition of subjective satisfaction variables in Model of women resulted in an increased $R^2$-value.

Objective: This study was performed to evaluate the child-care teachers' job in relation to physical work. Background: Child-care teacher is directly related to the quality of child care. And their physical activity is higher than general education teachers because the proportion of day care is high. But analyzes of child-care teachers' job burdens and the work environment associated with physical activity is not well established. Method: To conduct this study, the child-care teachers' job was classified into 18 physical works. After classification, posture was evaluated by ergonomic posture evaluation schemes of OWAS, RULA, REBA and evaluated for each physical part. Next, musculoskeletal subjective symptoms were analyzed. Results: The results showed the following: The highest assessment on the posture evaluation was "helping children to ride a school bus", "feeding: meal/snack", "brushing children's teeth" and "arrangement of nap-stuff". The rank of high-risk assessment on the neck/trunk/leg part was arranged by: "feeding: meal/snack", "helping children to ride a school bus", "making nap", "arrangement nap-stuff" and "brushing children's teeth". The rank of high-risk assessment on the upper limbs part was arranged by: "helping children to ride a school bus", "the bust - group activity", "meal/snack time - preparing, feeding, arrangement", "nap time - preparing, arrangement", "brushing children's teeth", and "using the toilet". According to the results of each musculoskeletal subjective symptom, teachers ordered the pain area as follows: waist, shoulder, leg/feet, and neck, and they showed more pain on trunk than the upper limbs. Conclusion: To sum up the results from ergonomic posture evaluation and a subjective symptom, the following are high working pressures: "feeding: meal/snack", "the bust - group activity", "making nap", "brushing children's teeth" with deep bending and waist twisting, "helping children to ride a school bus", "brushing children's teeth" with lifting shoulder; "meal/snack time - preparing, arrangement", "nap time - preparing, arrangement", and "using the toilet" with moving or an up-down position in their job. Application: The results of this study might be information for improvement of the child-care teachers' job environment.

Repetitive movement, inadequate working posture, overuse of force, physical contact with sharp edge, vibration and temperature were well known risk factors of WMSDs (Work-related Musculoskeletal Disorders). Many researchers have investigated the relationship between inadequate working postures and incidences of WMSDs of the upper extremities, whereas relatively few researchers have tried to evaluate workload associated with the lower-body postures. The effects of lower-limb postures including various knee flexion angles on the subjective discomfort, heart rate and EMG of lower-limb muscles were investigated in this study. Thirty graduate students were asked to maintain thirteen different body postures, and heart rate and EMG data of five muscle groups (electro spine, biceps femoris, vastus medialis, gastrocnemius and tibialis anterior) from each posture were collected during fifteen minutes sustaining tasks. All participants were also asked to report their discomfort ratings of body parts. Results showed that high subjective discomfort ratings and heart rates were reported at the postures of knee angles of $60^{\circ}$ and $90^{\circ}$, whereas low discomfort ratings were founded at the postures of chair heights with 20cm, 40cm, and sitting with crossed legged. The change of median frequency for each muscle group during fifteen minutes tasks was investigated for each body posture to evaluate the relationship between muscle fatigue and body posture. It was found that the trends of changes of median frequency were different based on muscle group as well as lower-limb body posture from this study.

This study examined the relationships among perceived values(environmental value, functional value), perceived risk, subjective norm, pro-social behavior, product attitude, and usage intention related to car-sharing service. The study also explored the moderating role of possessive desire between the antecedent variables and consumer attitude. 238 survey responses of Chinese consumers were analyzed by structural equation modeling. It is indicated that environmental value, functional value, subjective norm, pro-social behavior had positive effects on attitude, thereby affecting the usage intention of this service. Possessive desire moderated the relationship between environmental value, subjective norm and attitude. These results are expected to provide various marketing strategies for sharing economy services.

The purpose of this study was to investigate the effects of social support, parenting stress, and subjective hapiness on the depression of working mothers who are raising their children and to investigate alternatives to reduce their depression, and provide a practical program based on the study. In this study, we used hierarchical regression analysis to examine the variables that affect the depression of the working mothers. The results of this study showed that in the first stage, support of family, which is a sub factor of social support has a negative effect on depression. In the second stage, parenting stress had a significant effect on the depression of the working mothers. In the third stage, subjective hapiness has a negative effect on the depression of the working mothers. The relationship between variables such as social support, parenting stress, and subjective hapiness of these mothers were revealed, and the implications of lowering the depression of mothers were discussed based on the result of this study.

Purpose: The theory of planned behavior (TPB) was used to investigate how the psychological constructs of attitude, subjective norms, and perceived behavioral control (PBC) affect the individual intention of behaviors in adults. Social support is also important in enabling the stability of healthy eating. This study examined the relationship between three major constructs of TPB as well as social support and the intention of healthy dietary behaviors in adults residing in Beijing, China using the extended TPB. Methods: The study questionnaire was based on previously validated items and an online survey was conducted from October to November 2020. Using a total of 244 Chinese adults in Beijing, multiple linear regression analysis was used to test the relationships between three major constructs of TPB as well as the social support and intention of healthy eating. Results: Among the three major constructs of TPB, subjective norms (p = 0.044) and PBC (p = 0.000) were significantly related to the behavioral intention of healthy eating (p = 0.000), and the model explained 76.6% of the variance of the behavioral intention from the three constructs of TPB included in the multiple linear regression model. The additional inclusion of social support to the model did not increase the explanatory power of the model to describe the behavioral intention of healthy eating. The subjective norms (p = 0.040) and PBC (p = 0.000) were still significant where social support did not explain the variance of the behavioral intention adequately. Conclusion: The subjective norms and PBC may be potential determinants of the behavioral intention of healthy eating in adults residing in Beijing, China. These study results can be used to promote healthy eating in Chinese adults living in urban areas. Large-scale intervention studies will be needed to determine if social norms and PBC predict the actual behaviors of healthy eating in Chinese adults.

This study tested the possibility of applying the integrated social cognitive career theory for workers with disabilities to explore ways of predicting and enhancing their subjective well-being. It analyzed 952 adults who were employed for three years, among the workers who had participated in the Panel Survey of Employment for the Disabled from 2016 to 2018. The results showed that disability acceptance was positively related to occupational self-efficacy, job satisfaction, and life satisfaction with statistical significance, and that occupational self-efficacy had a partial mediating effect on the relationship between job satisfaction and disability acceptance. Moreover, both auto-regressive and cross-lagged effects between disability acceptance and job satisfaction were found to be statistically significant. These findings imply that disability acceptance and occupational self-efficacy can be regarded as important factors to increase the subjective well-being of workers with disabilities.

Based on the basic ideology of health care, this study realized the seriousness of annual unmet medical need and conducted a study to confirm the relationship between the subjective perception of regional healthcare environment and unmet medical needs. The independent variable was classified into attitude 'satisfaction' and 'unsatisfaction' toward regional healthcare, and the dependent variable was classified as whether unmet medical needs occurred annually. Based on previous studies, the control variables were selected as demographic and socioeconomic characteristics that can affect the occurrence of unmet medical care annually and characteristics related to health behavior. Descriptive statistics were conducted for each variable on the extracted sample, and multivariate survey logistic regression analysis was conducted to confirm the association between variables. As a result, more unmet medical needs occurred annually than those who were satisfied with the medical services in the area where they lived. In addition, more unmet medical need occurred annually in "unsatisfied" households compared to households "satisfied" with local medical services. In residential areas, women live in "metropolis" and "rural areas" compared to "urban," women live in men, lower education levels, and poor subjective health levels, and less satisfied with local medical services. As such, the impact of environmental factors in the community on the use of health and medical services is one of the major areas of interest in the field of health science, such as health policy and social dynamics. Therefore, hospitals in each region need to make efforts in terms of hospital management to increase the overall satisfaction of medical services in the region by continuously monitoring the attitude of residents to achieve universal health security, and policymakers should also be interested and propose new policies.

The present study was intended to measure the level of psychosocial stress and fatigue symptom according to the various characteristics such as sociodemographic, health-related, job-related, job stress factors, and psychosocial factors among nurses working at ward and operating room in university hospitals, and to reveal the relation between these factors and psychosocial stress and fatigue symptom. The self-administered questionnaires were given to 220 nurses working at ward, and 147 nurses working at operating room in 4 participating hospitals located in Daejeon City during the period from July 1st to Aug 31st, 2012. As a results, the factors related to the psychosocial stress of nurses working at ward were age, subjective health status, job career, satisfaction of work, fit to the job, job demand, job control, coworker support, self-esteem, locus of control, type A behavior pattern. In operating room, there were age, sleep hours, subjective health status, job career, physical burden of work, satisfaction of work, fit to the job, consider quitting the job, job demand, job control, type A behavior pattern. The factors related to the fatigue symptoms of nurses working at ward were age, leisure time, subjective health status, satisfaction of work, consider quitting the job, job demand, locus of control, type A behavior pattern. In operating room, there were age, subjective health status, physical burden of work, supervisor support, coworker support, locus of control. Based on the study results, we suggest that the factors related to psychosocial stress and fatigue symptom of nurses were different from working station. We need development and application of programs to keep under management psychosocial stress and fatigue symptom.

This paper analyzes qualitatively the stereo 3D content factors causing viewer's discomfort. For this, we perform a subjective test that each subject strokes a specific key whenever he (she) feels discomfort during watching a stereo 3D contents. Also we extract the data for the factors in the 3D contents to obtain their quantitative values and the amounts of the temporal changes. Those two sets of data are used to analyze the contents to find the factors which cause viewer's discomfort. The factors to be considered are the amount and the frequency of the disparity changes, story of the contents, situation or environments of a scene, movement and the position of the camera, color and luminance information as well as disparities themselves. We analyse the various strong and weak factors and their composites to find how much discomfort each factor or composite causes. We also show the situations and their related factors that causes less discomfort than the amount of their disparities.
