Purpose : In this study, we aimed to measure how respiratory muscle activity changes as posture changes. We also aimed to measure the inspiratory sternocleidomastoid (SCM) and upper trapezius (UT) muscle activities as well as expiratory rectus abdominis (RA) and oblique abdominis (OA) muscle activities in healthy male and female university students in their twenties. Methods : Using the percentage of reference voluntary contraction (% RVC) with electromyography, we measured the SCM, UT, RA, and OA muscle activities in 16 healthy male and female university students in their 20s according to position change and breather tool use. Results : We found that the average value of inspiratory and expiratory muscle activities by posture was highest when using the breather tool. When using the tool with 10-mm and 2-mm straws for standard breathing at rest in the sitting position, a statistically significant increase in SCM, UT, and OA activities occurred (p < 0.05). For standard breathing at rest in the supine position, a statistically significant increase in SCM, RA, and OA activities occurred (p < 0.05). Conclusion : In clinical application, it may be better to use a respiratory muscle-strengthening tool to increase the activity of inspiratory and expiratory muscles.

최근 들어 제주도내 도심지에서 주로 시공이 이루어지는 하수관거 정비공사 및 일부 도로공사 현장의 암 터파기 시공에서 무진동 굴착공법이 사용되고 있으나, 단위 물량에 대한 공사비를 산정함에 있어서 적정한 단가가 제시되지 못하는 문제점이 있다. 따라서 본 연구에서는 제주 지역 인근 현장에서 암터파기 작업에 활용되고 있는 무진동 굴착공법에 대한 현장 모니터링을 바탕으로 일위대가방식과 작업조 방식의 생산성을 비교 분석하였다. 이를 위해 35개 현장의 작업 데이터를 수집하였고, 30개 데이터를 통해 희귀식을 도출하였으며, 나머지 5개의 자료를 통해 검증을 실시하였으며, 이를 통해 작업조 방식의 1일 작업물량은 16.43㎥ 임을 도출하였다. 또한 작업조 방식의 공사비의 산정을 위해 현장여건을 고려한 장비의 조합과 작업인원에 차이를 둔 노무량의 조합을 도출하였다. 회귀분석을 통해 도출된 작업조의 1일 작업물량(16.43㎥)에 근거한 공사비를 산출하였고, 이를 일위대가 방식의 공사비와 비교, 분석하였다. Recently, the non-vibration mass excavation method is used on sewage pipes and road construction sites in Jeju. However, a construction cost estimation based on the unit quantity does not provide a proper unit price. In this study, a comparison of the productivity of the standard quantity-per-unit costing method and the one of the work crew combination method was made based on the site monitoring of the non-vibration mass excavation method that is used in construction sites near Jeju. For this, data of 35 sites were collected: a regression equation was derived from the 30 data, and verification was carried out through the remaining 5 data. The analysis concluded that a day’s workload is 16.43㎥. In addition, a combination of the equipment considering the site conditions and the amount of labor, which varies with the number of work crew was obtained in order to estimate the construction cost of the work crew combination method. The construction cost was calculated based on the one-day workload (16.43m3) derived from the regression analysis. The cost then was analyzed and compared with the standard quantity-per-unit costing method.

The purpose of this study was to investigate the effects of angular velocity on muscle strength and activity of knee flexor and extensor. Subjects was classified into three groups, which were 60°/sec angular velocity group(n=10), 180°/sec angular velocity group(n=10) and 240°/sec angular velocity group(n=10). Each group was applied to perform the isokinetic exercises on flexion muscle group for each 7 times in 3 set(2 days per a week for 4 weeks). Muscle strength was measured using peak torque of quadriceps femoris and muscle activity was measured using RMS(roots mean square) of rectus femoris, biceps femoris, and semitendinosus. The results were as follows: 1. The peak torque was significantly increased after 4 weeks application of 60°/sec angular velocity isokinetic exercise(p<.05), however, it was not significantly after 180°/sec angular velocity isokinetic exercise application, and 240°/sec angular velocity isokinetic exercise application(p>.05). 2. The muscle activity was significantly increased after 60°/sec angular velocity isokinetic exercise application on biceps femoris and semitendinosus(p<.05), however, it was not significantly after 180°/sec angular velocity isokinetic exercise application, and 240°/sec angular velocity isokinetic exercise application(p>.05). This study showed that 60°/sec angular velocity isokinetic exercise application were effective treatment strategy on increase of muscle strength. Therefore, it could be considered as a treatment method in the athlete and patients with musculoskeletal disease.

Stroke is the leading cause of adult disability and the third leading cause of adult death in the world. Stroke has an impact on the physical, psychological and social dimensions of quality of life. An increasing number of authors have reported a deterioration of the quality of life in a large proportion of patients after a stroke. Just as satisfaction with each dimension varies to everyone, the importance of each dimension also varies and does not impact equally on the quality of life. So assessment on the quality of life has to adopt a multidimentional approach and to make use of the subjective and objective indicators.
