Purpose : The purpose of this study was to examine the effects of waist mobilization technique intervention for patients with chronic back pain on balance and the low back pain disability index. Methods : The subjects were 30 patients with chronic back pain. They were sampled and divided into a manual therapy group and a spinal decompression group. 15 subjects were randomly assigned to each group. Each training in this study participated for 6 weeks, 5 times a week, once a day, 15 minutes a day. Balance ability was measured with a balance analyzer, and the low back pain disability index was measured using the Oswestry Disability Index (ODI). Results : In the balance abilities, there was a significant difference in the manual therapy group compared to the spinal decompression group. In the low back pain disability index, there was a significant difference in the manual therapy group compared to the spinal decompression group. Conclusion : The analysis results of the effect of 6 weeks of waist mobilization technique intervention on the balance and low back pain disability index for patients with chronic back pain revealed that the manual therapy is more effective for static and dynamic balance ability and the low back pain disability index. In the future, we can promote independent life skills and expect a rapid recovery of patients with chronic back pain. Based on this study, further studies are needed on the effects of balance, the mechanical properties of muscle, and the low back pain disability index depending on various manual therapy techniques.

Level 3 autonomous vehicles require conditional autonomous driving in which autonomous and manual driving are alternately performed; whether the driver can resume manual driving within a limited time should be examined. This study investigates whether the demographics and subjective driving tendencies of drivers affect the take-over performance. We measured and analyzed the reengagement and stabilization time after a take-over request from the autonomous driving system to manual driving using a vehicle simulator that supports the driver's take-over mechanism. We discovered that the driver's reengagement and stabilization time correlated with the speeding and wild driving tendency as well as driving workload questionnaires. To verify the efficiency of subjective questionnaire information, we tested whether the driver with slow or fast reengagement and stabilization time can be detected based on machine learning techniques and obtained results. We expect to apply these results to training programs for autonomous vehicles' users and personalized human-vehicle interfaces for future autonomous vehicles.

Facilities used by senior citizens, infants, and disabled people have characteristics that make it difficult to escape on their own or require a lot of evacuation time. Therefore, to ensure safety in case of fire, clear measures for securing safety of facilities, fire response methods, and training are required in accordance with the regulations. In case of postnatal care center facilities, newborn babies and mothers reside 24 hours a day, and as they are located in high-rise and multi-use facilities, measures for fire safety are necessary, but the domestic manual lacks. Accordingly, a field survey for security of the manual revealed that the establishment of awareness and facilities on temporary waiting areas and smoke control, which are easy for evacuation and fire safety, was a problem.

This study was conducted to investigate the effects of therapeutic climbing training on upper limb function and quality of life of stroke patients and to suggest possibilities for clinical intervention. This study investigated 14 stroke patients who were assigned to either a treatment climbing training group or a control group (n=7 each). The experimental groups performed general physical therapy and occupational therapy. In addition, therapeutic climbing training using the Potsdam model was conducted for 30 minutes three times a week for 6 weeks. The control group performed general physical therapy and occupational therapy. A manual function test was used to evaluate upper limb function, and a short form 36-item questionnaire was used to evaluate quality of life. The results showed that there was a significant difference in upper limb function of the experimental group according to time (p<0.05). There was also a significant difference in the quality of life according to time in the experimental group, and a significant difference in quality of life between the experimental group and the control group (p<0.05). Therapeutic climbing training by stroke patients positively affected quality of life by increasing the SF-36 scores and upper limb function. Taken together, these findings confirmed that training using therapeutic climbing is valuable for rehabilitation and clinical intervention of stroke patients.

Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. The central nervous system deals with stabilization of the spine by contraction of the abdominal and multifidus muscles in anticipations of reactive forces produced by limb movement. Recent evidence indicates that the lumbar multifidus muscle and transversus abdominis muscle may be involved in controlling spinal stability. Stabilization training in neutral spine is an integrated approach of education in proper posture and body mechanics along with exercise to improve strength, flexibility, muscular and cardiovascular endurance, and coordination of movement.
