The work posture impose additional stress upon human workers so that it should be carefully considered in designing works. However, we have a lot of manufacturing plants which convert their standing workplace to sedentary one. To confirm the validity of that trend, the authors conducted an experimental study, and compared the results. The results of the EMG and the self-cognitive symptoms, in general, showed a correspondent trend that the sedentary work posture was rated more comfortable. At the beginning of the work, complaint of the lowerback was higher whereas that of the lower leg and the feet went higher as the time elapsed. If the weight of workpiece were heavier than 500g, increasing rate of bodily discomfort in the sedentary posture were greater than that of the standing posture. In the meanwhile, the standing posture was consistently superior to the sedentary posture in its performance. Thus, in conclusion, for a light assembly work, sedentary work posture would be recommendable because bodily discomfort would be larger irrespective of the small increase of performance increase.

The purpose of this study was to investigate how the increased sedentary behavior due to COVID-19 on physical factors to maintain health. The subjects of the study were 33 office women who mainly lead a sedentary behavior. The group settings were divided into high sedentary behavior groups(n=11), middle sedentary behavior groups(n=11), and low sedentary behavior groups(n=11) according to the hours of sitting down living. There was no significant difference between the groups in the VO₂max and EPOC, the level of lactate in blood showed a significant difference immediately after exercise(p<.05) and at 15(p<.001) and 20(p<.001) minutes of recovery, and the degree of recovery was more smooth in the low sedentary behavior groups. These results suggest that the difference in time according to the degree of sedentary behavior will affect the factors for maintaining health. Therefore, it is considered necessary to minimize sedentary behavior time even in the COVID-19 situation where the time spent in a personal space increases.

The purpose of this study is to analyze the characteristics of the non-sedentary in contemporary multi-housing planning through the understanding and interpretation of the modern nomadic life. A document research method was used to analyze and classified the spatial characteristics and development of the non-sedentary dwelling spaces since 20th century. Finally, today the applicable cases of non-sedentary space are as follows; the sharing housing, the adapting housing, and temporary housing for the multi-purpose spaces, huge spaces and the industrialization housing. First of all, in order to conform the concept of nomadism, the theory and characteristics were divided into three aspects; The concept of thought of lines, events and Rhisome, and the spatial characteristics of fluidity, multiplicity and the non-hierarchy, that is mainly based on the philosophy of Gilles Deleuze. This study attempted to analyze how the concept of non-sedentary dwelling space has been developed in what form and method they have been applied and interpreted in the historical background. It attempted to resolve the concept of movement and mobility through the experiment so that they might apply to the space of contemporary city.

Objectives: This study aims to determine the relationship between sedentary behavior and oral health factors in adolescents. Methods: Based on the data from the online survey on youth health behaviors, general characteristics, sedentary behavior was classified as practiced for less than 2 hours, and not practiced for more than 2 hours, and oral health was classified brush teeth after lunch, sealant, oral symptoms. The analysis methods were complex frequency analysis, complex chi-square test, and complex logistic regression analysis. Results: In case of brush teeth after lunch during the week, those who practiced it was 1,025 times higher than those who did not practice it, and in the case of oral symptoms practice was 0.915 times lower than not practice. As a result of adjusted general characteristics, for brushing teeth after lunch during the week, practice was 1,090 times higher than no practice. Conclusions: The relationship between sedentary behavior and oral health behavior and oral symptoms could be confirmed. Therefore oral health promotion programs according to sedentary behavior are needed to promote oral health for adolescents.

Purpose: This study examined the combined effects of sugar-sweetened beverage (SSB) consumption, screen-based sedentary behaviors, and sleep duration on adolescent obesity. Methods: It followed a cross-sectional study design and conducted secondary analysis on data from 20,497 high school students who participated in the 17th (2021) Korea Youth Risk Behavior Web-based Survey. This study underwent logistic regression analysis in complex sampling analysis. Results: The combinations of low and medium consumption of SSBs, excessive screen-based sedentary behaviors, and short sleep durations were associated with a 1.18 and 1.12 fold increased likelihood of obesity (95% confidence interval [CI]=1.03-1.35) and (95% CI=1.02-1.22), respectively. The combination of high SSB consumption, appropriate screen-based sedentary behaviors, and short sleep duration (adjusted odds ratio [aOR]=1.15, 95% CI=1.01-1.31) and high SSB consumption, excessive screen-based sedentary behaviors, and short sleep duration (aOR=1.40, 95% CI=1.16-1.69) were associated with obesity. Conclusion: Integrated and tailored programs considering combination patterns of SSB consumption, screen-based sedentary behaviors, and short sleep duration need to be developed for preventing adolescent obesity.

There is a dearth of Korean studies on dehydration, one of the health risks for adult women. This study analyzed the subjects of the 2016~2018 National Health and Nutrition Examination Survey (KNHANES) to investigate the relationship between nutrient intake ratios and sedentary time in dehydrated women. Body mass index and waist circumference in the dehydrated group (DG) were significantly higher than the normal group (NG). Intake of other liquids in the DG was significantly higher than in the NG, but total water intake in the DG was significantly lower than in the NG. Compared to the 600 sedentary minutes or more per day group, the odds ratio of dehydration was significantly higher in the less than 300 sedentary minutes per day group (1.871 [95% CI: 1.579~2.215], P<0.001). Compared to the drinking over 6.0 cups of water per day group, the odds ratio of dehydration was significantly higher in the 3 cups or fewer per day (OR [95% CI] is 1.198 times [1.019 to 1.408], P<0.05), and 6.0 cups or fewer group (OR [95% CI] is 1.162 times [1.018 to 1.326], P<0.05). The results of this study showed that the total water intake was relatively lower in the ≥600 sedentary minutes per day group compared to the 300 sedentary minutes per day group, making them more vulnerable to dehydration. The nutrient intake ratios were higher in the dehydration group than in the normal group. In conclusion, emphasis should be placed on the importance of hydration and nutrition education for adult women in the workplace.
