Purpose: The purpose of this study was to investigate the availability of software for rehabilitation with the Kinect sensor by presenting an efficient algorithm based on machine learning when classifying the motion data of the PNF pattern if the subjects were wearing a patient gown. Methods: The motion data of the PNF pattern for upper extremities were collected by Kinect sensor. The data were obtained from 8 normal university students without the limitation of upper extremities. The subjects, wearing a T-shirt, performed the PNF patterns, D1 and D2 flexion, extensions, 30 times; the same protocol was repeated while wearing a patient gown to compare the classification performance of algorithms. For comparison of performance, we chose four algorithms, Naive Bayes Classifier, C4.5, Multilayer Perceptron, and Hidden Markov Model. The motion data for wearing a T-shirt were used for the training set, and 10 fold cross-validation test was performed. The motion data for wearing a gown were used for the test set. Results: The results showed that all of the algorithms performed well with 10 fold cross-validation test. However, when classifying the data with a hospital gown, Hidden Markov model (HMM) was the best algorithm for classifying the motion of PNF. Conclusion: We showed that HMM is the most efficient algorithm that could handle the sequence data related to time. Thus, we suggested that the algorithm which considered the sequence of motion, such as HMM, would be selected when developing software for rehabilitation which required determining the correctness of the motion.

This research was conducted to understand and analyze the physical awareness symptoms of college students and get fundamental research data essential to provide efficient student guidance and public health service at schools. The survey was carried out for 1 month from May 7th, 2001 to June 7th, 2001. The interviewees were 950 enrolled students at junior colleges in Daegu. 26.5% of them were men and 73.5% women. Among the surveyed, public health majors were 76.9%. Daytime students were 64.1 %, and the majority of the students, 42.8%, were atheistic. 56.0% of the students grew up in big cities, 22.2% in medium and small-sized cities, and 21.8% in farming and fishing communities. 66.1 % used public transportation. The majority of the students, 48.7%, answered that the satisfaction level for their majors was average. The result shows that the ocular fatigue was indicated as a greatest complaint, and the female students showed the higher complaint rate than the males. In the study of the complaining rate of physical symptoms by major, the public health majors showed the highest complaining rate in gasping when going up/down stairs, shoulder pain, a burning feeling on empty stomach, and leg/knee pain. On the other hand, the highest complaint factors for the technical majors were ocular fatigue and the feelings of heavy head. In the study of the complaining rate of physical symptoms by transportation, gasping during going up/down stairs and shoulder pain were most common, which were 52.2% and 36.0% respectively. In the study of the insecurity response distribution by transportation, college students who drive a car showed 3.8% and students using public transportation 3.7%. In the study of the insecurity response by subject satisfaction, students who answered dissatisfactory were 8.3%, average 3.9%, satisfied 3.0%. Therefore, it was concluded that students who were dissatisfied with their subjects showed the higher rate of insecurity response. it can be recommended that a school health education program regarding ocular fatigue and shoulder pain should be developed.

Objectives: To quantify disability level in salespeople with concurrent low back pain (LBP) and to determine the relative associations between demographic, occupational, psychosocial and clinical factors and back disability. LBP is the most common cause of work-related disability in people under 45 years of age and the most expensive cause of work-related disability, in terms of workers' compensation and medical expenses. Evidence suggests high prevalence of LBP in salespeople. Methods: A cross-sectional survey was conducted in which 184 saleswomen with a current episode of self-reported LBP working in a large up-scale department store filled out a battery of 6 self-administered questionnaires and received a standardised physical examination. Results: Saleswomen with concurrent LBP had low disability levels. Factors significantly associated with disability were pain intensity, measured by a visual analogue scale, in the past week (p < 0.001), physical and mental health status (p < 0.001, p = 0.003, respectively), fear avoidance scores for both work and physical activities (p = 0.031, p = 0.014, respectively), past history of LBP (p = 0.019), and self-reported frequency of pushing or pulling objects placed in high positions during work (p = 0.047). A significant level (45%) of the variance in disability status was explained by these variables. Conclusion: In clinical management of LBP workers who required prolonged standing, such as salespeople, clinicians should look for modifiable risk factors associated with disability. Specific measures need to be taken to prevent disability due to LBP among salespeople.

Background: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. Methods: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. Results: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Conclusion: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

The purpose of this study was to identify health literacy among elderly and to investigate the relationships between healthy literacy and health status. A cross-sectional study was conducted with a sample of 158 participants between July and December 2019. The linguistic and functional health literacy (using the KHLAT and NVS) and self-rated physical and mental health were assessed. Above third of elderly have difficulties reading and understanding linguistic and functional health literacy. There were significant differences in health literacy according to residence, spouse, living together, educational level, occupation, monthly income, and number of diagnosed disease. Linguistic and functional health literacy and self-rated physical and mental health are closely related. Sociodemographic and disease related factors such as residence, educational level, monthly income, and multi-morbidity need to be considered when developing educational programs to improve health literacy. It could be possible to promote health status by improving the health literacy through individualized convergent educational program.

The purpose of this study is to identify the characteristics and factors of each area by considering the gender health of the elderly as the integration of mental, physical, emotional, and social gender health based on the WHO gender health. The sexual health of the elderly is significantly different by gender, academic background, and region, and there is a clear difference in mental, physical, emotional sexual health and social sexual health. The mental, physical and emotional sexual health of the elderly in urban areas, those with high education and male is high, but the elderly in the rural areas, those with low education, and female are high in social sexual health. The factors affecting sexual health are as follows. Mental sexual health was positively influenced by satisfaction of sexual life and sexual knowledge. Physical sexual health was positively influenced by life and spouse satisfaction, and emotional sexual health was positively influenced by sexual relationship, spouse satisfaction, sexual life satisfaction and sexual knowledge. Social sexual health has a negative (-) effect on spouse satisfaction and sexual relationships. Integrated sexual health in old age can affect subjective health and quality of life, leading to successful aging. Sexual health education is needed to form a safe and healthy sexual life and interpersonal relationship. The 'sex' that appears as a cumulative trajectory of life should be accompanied by the accurate sexual health awareness and sex education that encompasses all generations. Therefore, in the composition of sex health education program, it is necessary to reflect the components that can enhance the sensitivity of adulthood to strengthen understanding and communication of spouse.
