  • 기존 자가발전 운동기구의 경우, 가변저항을 사용하여 운동강도를 조절하기 때문에 Generator에서 생성된 에너지가 모두 소모되는 문제점이 있다. 또한 계통연계형 자가발전 운동기구의 경우에는 에너지 회수는 가능하지만 운동 강도 조절이 불가능한 단점이 존재한다. 따라서 본 논문에서는 계통연계를 통해 에너지 회수가 가능하고, 운동 강도 조절이 가능한 자가발전 운동기구용 DC/DC 컨버터를 제안한다. 제안회로는 가변저항을 사용하지 않고 입력임피던스를 통해 운동 강도를 조절하기 때문에 높은 에너지를 생성할 수 있고 계통연계를 통해 에너지 회수도 가능한 장점이 있다. 본 논문에서는 제안된 회로의 이론적 특성을 분석하고 모의실험을 통해 확인하였으며, 계통연계형 자가발전 운동기구에 적용하여 실험을 통해 우수성을 검증하였다.

  • 낙상은 노인의 신체적 건강은 물론 총체적 삶의 질을 위협하는 요인이다. 이 연구의 목적은 어떤 운동유형이 노인의 균형 능력 증진에 효과적인가를 확인하고, 이에 기초하여 노인 낙상 예방 운동 프로그램 개발에 필요한 기초 자료를 얻는 것이었다. 65세 이상 80세 미만의 여성 노인들을 스텝운동집단(21명), 코어근육운동집단(20명), 통제집단(21명) 중 한 집단에 무선 할당하였고, 8주 동안, 주 2회, 회당 20~30분의 운동을 처치하였다. 운동 효과는 기능적 균형검사(한발 정적균형검사)와 자기보고식 균형검사(낙상효능감, 균형자신감)로 평가하였다. 연구 결과를 요약하면 다음과 같았다. 첫째, 리드미컬한 스텝운동이 체간의 코어근육 강화운동보다 기능적 균형 증진에 효과적이었다. 특히, 눈을 뜨고 측정하는 한발 정적 균형검사에서 스텝운동의 효과가 뚜렷하게 나타났다. 둘째, 자기보고식 균형검사에서도 스텝운동이 코어근육운동보다 우수한 결과를 보였다. 특히, 리드미컬한 스텝운동이 체간의 코어근육운동보다 낙상 효능감 증진에 효과적이었다. 이상의 연구 결과를 종합해 볼 때, 리드미컬한 스텝운동이 체간의 코어근육운동보다 노인의 균형 능력 증진에 효과적이었다. 이는 리드미컬한 스텝운동이 하지 근육의 관여가 상대적으로 높고, 다양한 지면 변화 속에서 스텝운동을 수행하므로 낙상 발생 환경과 유사하며, 발목 고유수용성 강화에 적합한 운동유형이었기 때문이라고 사료된다. 따라서 향후 연구를 위해서 노인 낙상 사고가 발생하는 구체적인 동작 상황을 조사하고, 이에 기초하여 과제지향의 발목 고유수용성 감각강화 운동 중재 프로그램 및 운동 장비의 개발을 제안하였다.

  • Wearing the right sportswear is one of the essential points in exercising, which is mainly neglected. Sportswear should be suitable for the ambient temperature and not cause more heat or cold in the athlete's body. On the other hand, increased sweating and blood circulation during exercise should not cause fatigue or heatstroke in the athlete. Nanotechnology has grown significantly in the field of producing more efficient equipment in the field of sports. The increase in demand in sports for complete sports equipment has revealed the necessity of using the highest quality materials in this sector. In the world of championship sports, a minor change in equipment can lead to significant changes in causing failure and victory. Since the sole is the most critical part of sports shoes, with the introduction of nanotechnology and nanocomposites, it is possible to help athletes rush and increase their sense of calm and satisfaction. Using nanocomposites in the soles of shoes can improve some of their characteristics, prevent the smell and sweat of shoes, and induce water repellency in these shoes. In this research, titanium dioxide (TiO2) nanocomposite, along with cellulose, has been used to create antibacterial and hydrophobic properties in the soles of sports shoes. The synthesized nanocomposite has been synthesized using the least amount of chemicals, which shows this method's easy and cost-effective synthesis.

  • Objective: Cervical stabilization exercises are frequently to improve strength and endurance of cervical muscles. The purpose of this study was to identify changes in head repositioning accuracy (HRA) and neck proprioception through cervical stabilization exercises in healthy adults. Design: One group pretest-posttest design. Methods: Thirteen participants with no previous history of neck pain or injury to the cervical spine were recruited. HRA was measured by equipment including laser pointer, helmet, eye patch and marking pens. The distance between the spot where the beam had stopped and the center of the graph paper was measured three times with the averaged value used as the head repositioning accuracy. Neck proprioception was measured by a cervical range of motion device (CROM). Subjects wore the CROM tester and were to look straight ahead while bending his/her neck. Subjects were instructed to perform extension, lateral flexion and rotation, and the values were then measured and recorded. The measurements were performed pre-intervention, and after cervical stabilization exercise. Results: There was no significant difference on HRA after intervention. In addition, there was no significant difference on neck proprioception compared with pre-intervention. Conclusions: The present study did not identify any effect on HRA and neck proprioception of cervical stabilization exercise. Further investigations are required to elucidate this in old aged participants and patients with neck pain.

  • Background: Tension-type headaches, which make up the highest proportion of headaches, are prone to develop into chronic tension-type headaches (CTTH). The characteristic of CTTH in patients is that the active myofascial trigger point (ATrP) which causes pain in the muscles of the back of the head is increased, compared to the normal headache and moves the head position forward. Objective: The aim of this study was to investigate the effects of myofascial release (MFR) and posture correction in effectively improving neck function and sleep quality in the symptoms of CTTH patients. Design: Observer-blind study Methods: To reduce ATrP, MFR was applied and exercise was also applied to correct posture. The subjects of this study were 48 individuals randomly divided into three groups; The MFR group using the MFR technique; The MFR with exercise group subject to both the MFR technique and forward head position correction exercises (MFREx), and the control group. MFR and MFREx groups were given the relevant interventions twice a week for four consecutive weeks, and went through the number ATrPs, range of motion (ROM) of neck, Neck Disability Index (NDI) and the Pittsburgh Sleep Quality Index (PSQI) before and after the intervention. A physical therapist, who was fully familiar with the measuring methods of the equipment, was the measurer and not aware of the target's condition was blinded to take measurements only before and after intervention. Results: There was a significant improvement in the ATrP, Neck ROM, NDI and PSQI in the group of patients to whom the MFR technique and MFREx were applied. MFREx was more effective in increasing neck mobility. Conclusions: According to this study, the application of MFR is effective in improving neck movement and sleep quality in chronic tension headache patients.
