  • Microbial cellulose has many potential applications due to its excellent physical properties. The production of cellulose from Acetobacter xylinum in submerged culture is, however, beset with numerous problems. The most difficult one has been the appearance of negative mutants under shaking culture conditions, which is deficient of cellulose producing ability. Thus genetic instability of Acetobacter xylinum under shaking culture condition made developing a stable mutant major research interest in recent years. To find a proper type of bioreactor for the production of microbial cellulose, several production systems were developed. Using a reactor system with planar type impeller with bottoms sparging system, it was possible to produce 5 g/L microbial cellulose without generating cellulose minus mutants, which is comparable to that of static culture system.

  • Interspecific relationship between a euryhaline rotifer Brachionus rotundiformis and a cyclopoid copepod Apocyclops borneoensis was investigated in the laboratory culture. In a mixed culture of B. rotundiformis and A. borneoensis, population growth of B. rotundiformis was suppressed from day 10, while growth in a monoculture population continuously increased throughout the experimental period. However, the population growth of A. borneoensis in the mixed culture did not markedly differ from that in a monoculture population. Suppression of B. rotundiformis growth coincided with a decrease in the numbers of both non-egg-bearing and egg-bearing females, and increasing resting egg formation. Growth of A. borneoensis was not affected by the presence of the rotifer. However, relative growth index of ovisac bearing females in the mixed culture was 1.62 times higher than that in the monoculture. Presence of the copepod did not greatly reduce the food available to the rotifer population. The rotifer B. rotundiformis responded in a unique way, to stresses such as physical damage (filtering by A. borneoensis) with the production of many resting eggs to increase its chances of survival.

  • This study aimed to suggest basic data required to improve the awareness of physical therapy and examine physical therapists' awareness of the independent establishment of physical therapy clinics. To do so, 175 physical therapists in Gyeongnam areas were surveyed. Their general characteristics were statistically analyzed using SPSS 10.0, and their current workplace, working conditions and job satisfaction were analyzed using chi square distributions. The awareness of independent establishment was analyzed using the Excel program. The statistical significance (a) in this study was set at 0.05. Their interest in physical therapy was surveyed by gender, and 52.2% of males showed interest, higher than that of females. The satisfaction level of those who work in general hospitals with self-development was 32.8%, higher than that of those who work in clinics. To the question about independent establishment, 83.4% agreed to independent establishment, and 57.5% answered that the first thing to do before independent establishment is acquiring professional theoretical knowledge and clinical treatment skills. In terms of the areas of establishment, 45.2% answered physical therapy for the musculoskeletal system, and 39.7% answered that the awareness of doctors is the biggest obstacle to independent establishment. It will be necessary to ensure physical therapists acquire professional theoretical knowledge and clinical treatment skills and to improve awareness between physical therapists and doctors. In addition, it is considered that departments related to physical therapy need to be unified as a four-year course, and the independent establishment of physical therapy clinics is required to be legalized.

  • Objective: This study aims to conduct a comprehensive review of monitoring systems to monitor and manage physical function of community-dwelling elderly living alone and suggest future directions of unobtrusive monitoring. Design: Literature review Methods: The importance of health-related monitoring has been emphasized due to the aging population and novel corona virus (COVID-19) outbreak.As the population gets old and because of changes in culture, the number of single-person households among the elderly is expected to continue to increase. Elders are staying home longer and their physical function may decline rapidly,which can be a disturbing factorto successful aging.Therefore, systematic elderly management must be considered. Results: Frequently used technologies to monitor elders at home included red, green, blue (RGB) camera, accelerometer, passive infrared (PIR) sensor, wearable devices, and depth camera. Of them all, considering privacy concerns and easy-to-use features for elders, depth camera possibly can be a technology to be adapted at homes to unobtrusively monitor physical function of elderly living alone.The depth camera has been used to evaluate physical functions during rehabilitation and proven its efficiency. Conclusions: Therefore, physical monitoring system that is unobtrusive should be studied and developed in the future to monitor physical function of community-dwelling elderly living alone for the aging population.

  • Purpose: This study aimed to analyze factors that influence the job satisfaction of physical therapists working in hospitals. Methods: The study was done using a self-administered questionnaire associated with job satisfaction, which was completed by 352 physical therapists working in hospitals. Results: The average job satisfaction score was 3.16. Sub-items scores for job satisfaction were higher for overall satisfaction (3.21) and lower for job satisfaction of achievement (3.12) than the average score. Job satisfaction of subjects showed statistically significant differences with regard to differences in sex, marriage, type of hospital, year of total career, type of patients and motivation level (p<0.05). The average job stress score was 2.38. The sub-items of job stress consisted of problems pertaining to physical environment (2.28), job demand (2.54), job autonomy (2.31), social support (2.14), job instability (2.36), organized management system (2.44), inner motive (2.24), and job culture (2.26). Multiple regression analysis revealed that job satisfaction became significantly lower with increasing levels of job stress. Conclusion: These results suggest that the job stress of physical therapists is closely related to their job satisfaction. An effort to reduce job stress may be helpful in improving the health and quality of life of physical therapists who work in hospitals.

  • This study selected fashion brands claiming to advocate feminism to analyze their characteristics and female images. For the study's data, online foreign feminist fashion brands were sifted from March 2017 to January 2018 and 28 clothing brands were selected. The study's results show that feminist fashion brands aim at the demassification and individualization of fashion products to be more inclusive of individuals' physical characteristics and diversity. Additionally, feminist brands entice consumption through communication and participation in online communities and through the value of social coexistence. The essential female image produced by feminist fashion brands deconstructs a socially idealized female image and expresses a sense of self-body positivity. In turn, the concept of self-body positivity is communicated through natural images of independent women with distinct identities based on differences in race, culture, and sexual orientation. Moreover, feminist fashion brands produce social images featuring independent women using active wear to engage in social activities. Casual wear is also used to reflect active women, while mannish looks and power suits express women's social status and professional abilities. Ultimately, these offer functionally active and rational images, combined with female images featuring long hair and makeup. Yet another type of female image seeks to create a new vision of women as diverse due to their various cultures, countries of origin, races, and individual tastes. These new images express women's physical differences, distinct identities, and diversity while simultaneously deconstructing pre-existing forms of clothing.

  • The Gwangju Daein Art Market, once declared as a declined market, was regarded as a success after an inflow of artists. However, the number of resident artists decreased from 100 at the end of 2015 to 39, to 9 in 2018, and to 6 in 2021. The project site showed signs of decline toward the completion of the project, leading to a Longitudinal study on the project's sustainability. The purpose of this study is to investigate the causes of outflow of artists and the network characteristics of the remaining artists from a sustainability perspective and thereby draw policy implications. As an analysis method, in-depth interviews and surveys were conducted. After that, we checked the remaining artists in 2018 and 2021 and identified the network characteristics. Based on the interview results, the causes of outflow were classified into programmatic, physical, and other factors. The results of a comparison showed that the levels of understanding, satisfaction, and frequency of exchange decreased. The study also provides policy implications. First, a sustainable, long-term program for the artists must involve the improvement of physical space. Second, participation in the market should be encouraged by working with artists on program composition or business progress. Third, programs for supporting exchange among artists should be further strengthened.

  • Purpose Wearable devices are widely used in our daily life. The purpose of this study is to investigate the relationship between persuasive designs of fitness trackers and users' physical activity behavior. Methods To test the research model, data was collected from a web-based survey in China, resulting in an effective sample of 166 usable questionnaires. The survey was restricted only to respondents who wear a fitness tracker. Results The sample surveyed in this study indicated that half of the respondents had been wearing a smart fitness tracker shorter than one year, and only 27% were long-time users (longer than two years). Dialogue support and social support strategies were both proved to be effective in increasing users' workout behavior intention. Social support strategies had a greater effect on behavior change than dialogue support strategies. Conclusion The findings from this study make several contributions to the practice. Wearable devices developers can employ the result from this study to help them design devices, which can persuade people to do more exercises and preserve a healthier life.
