This study aimed to investigate the immediate physiological responses, including heart rate, blood pressure, and rate pressure product (RPP), following squat exercises performed at three water depths (ground, knee depth, waist depth) and two speed conditions (60bpm speed, Max speed). The participants consisted of 10 men in their 20s with over 6 months of resistance exercise experience. For the 60bpm speed squats, participants performed 30 repetitions in 1 minute at a rate of 2 seconds per repetition, while for Max speed squats, they performed at Max speed without a set limit on the number of repetitions for 1 minute. All experiments were conducted with a random assignment. The study results showed that immediately after the aquatic squat exercise, the average heart rate, blood pressure, and cardiac load were higher in the order of knee depth, ground level, and waist depth at both 60bpm speed and Max Speed. At 60bpm speed, the heart rate was higher in the order of ground level, knee depth, and waist depth. Overall, exercise in an aquatic environment was considered to impose relatively lower physical burden compared to land-based exercise. Therefore, it is suggested that depending on individual fitness levels and exercise goals, appropriately combining aquatic exercise, which imposes lower immediate physiological burden, and land-based exercise may lead to safer and more effective exercise methods.

Purpose: This study aimed to investigate the effects of postural control exercise on the delayed heart rate increase in heart transplant patients. Methods: The subject was a female heart transplant recipient who had a delayed increase in heart rate during exercise. The intensity of exercise was performed at MBorg level 4. The A-B-A' and A-B-A'-B' designs were used to identify the changes in heart rate during active-assisted exercise, lower limb postural control exercise, and upper limb postural control exercise. Experiments were performed for four weeks. The heart rates at pre- and post-exercise were compared, and the time to reach MBorg 4 was measured. Results: In the active-assisted exercise, the average heart rates at pre- and post-exercise and after 10 min of exercise were 88, 89, and 87.7 bpm, respectively. In the repetitive comparison of pre- and post-exercise in the lower limb postural control exercise, the difference in the mean heart rate was 3.5 and 3 bpm in stable support and 14 and 14.5 bpm in unstable support, respectively. In the repetitive comparison of pre- and post-exercise in the upper limb postural control exercise, the difference in the mean heart rate was 6 and 4 bpm in stable support and 4 and 4.5 bpm in unstable support. The time required to reach MBorg 4 was short when both the upper and lower postural control exercises were performed in an unstable state. Conclusion: We suggest that combining proper postural control exercise with strength exercise and aerobic exercise, among others, may be effective in rehabilitating patients in the recovery stage after a heart transplant.

의료기관의 응급실은 환자의 생명을 다루는 긴박한 현장으로 환자에 대한 실시간 모니터링 및 관리가 필수적으로 요구되는 곳이다. 본 연구에서는 기존 응급실 진료 프로세스를 체계적으로 관리하고 모니터링 하기 위해 BPM 아키텍처를 도입하여 응급실 업무들을 표준화, 가시화함으로써 의료진의 신속한 응급 업무 대응이 가능한 응급신속대응관리시스템(EQRMS-Emergency Quick Response Management System)를 제안한다. 의료기관에서 BPM의 도입은 단순히 병원 경영 목표나 병원 내외부의 운영을 모니터링 할 수 있는 이점 이외에 병원 업무의 이윤을 극대화 할 수 있는 다양한 효과가 있다. 또한 임상위험수치 (CV-Critical Value)를 정의함으로써 복잡한 검사의 단순화와 검사 시간 단축, 검사의 오류 발생률 감소 등 환자의 안정성 제고 측면에도 크게 기여할 것이다.

본 연구에서는 항타시공성(BPM, blow per meter)을 고려하여 대구경 항타강관말뚝을 시공하였을 때 발생하는 폐색효과를 분석하였다. Coupled Eulerian-Lagrangian(CEL)해석 시 적용된 항타에너지는 파동방정식을 이용하여 산정하였고, CEL 대변형 3차원 유한요소 해석을 수행하여 말뚝 항타시공 과정을 모사하였다. 본 연구 결과, 말뚝 직경이 증가함에 따라 목표 깊이까지 소요되는 항타에너지는 증가(일정한 BPM인 경우에 해당함) 하였으며, 그 결과 soil plugging index(SPI)는 서로 유사하게 나타나지만 폐색효과는 감소함을 알 수 있었다. 또한, 말뚝의 근입 깊이가 증가할수록 SPI는 서로 유사한 값을 나타냈으나 관내토에서 발생하는 수평토압이 증가하게 되어 폐색효과는 오히려 증가하는 것으로 나타났다. 본 연구결과, 폐색효과의 대표적 영향인자인 말뚝 직경, 말뚝 근입 깊이, 지반 탄성계수, BPM에 따른 관내토의 수평토압계수 분포 경향을 제안하였다.

The Down-the-Hole hammer is one of the pneumatic drill equipment used for grinding, drilling, and mining. One the advantages of which is that a reduction work efficiency at deep site are relatively small compared to other drilling methods. Due to the large vibration in the underground area, it is difficult to measure the performance of the hammer, and hammer testing requires substantial production cost and operating expenses so research on the development of the hammer is insufficient. Therefore, this study has developed a dynamic simulation model that apprehends the operating principles of an 8-inch DTH hammer and calculates performance data such as performance impact force, piston speed, and BPM. By using the simulation model, design factors related to strike force and BPM were selected, and the influence of each design factors on performance was analyzed through ANOVA analysis. As a result, be the most important for BPM and the strike force are position of upper port that push the piston in the direction of the bit and in BPM, the size of the empty space between the bits and the piston is the second most important design factor.

Beam position measurement system can not only provide the beam position monitoring, but also be used for global orbit correction to reduce beam loss risk and maximize acceptance. The Beam Position Monitors (BPM) are installed along the synchrotron to acquire beam position with the front-end electronics and data acquisition system (DAQ). To realize high precision orbit measurement in the main heavy ion synchrotron and cooling storage ring of heavy-ion research facility in Lanzhou (HIRFL-CSRm), a series of alignment and calibration work has been implemented on the BPM and its DAQ system. This paper analyzed the tests performed in the laboratory as well as with beam based on the developed algorithms and hardware. Several filtering algorithms were designed and implemented on the acquired BPM raw data, then the beam position and resolution were calculated and analyzed. The results show that the position precision was significantly improved from more than 100 ㎛ to about 50 ㎛ by implementing the new designed filtering algorithm. According to the analyzation of the measurement results and upcoming physical requirements, further upgrade scheme for the BPM DAQ system of CSRm based on field programmable gate array (FPGA) technology was proposed and discussed.

uEFL is an open source solution to integrate general business/learning activities and processes. uEFL is originally developed to adopt LD (Learning Design) specification, which represents learning as various combination of learning activities with learning conditions and outcomes. Learning activities are described with participant's role, learning environment, and contextual sequence. This viewpoint resembles BPM (Business Process Modeling). uEFL can convert LD to BPM description. uEFL engine can run converted LD activity with other business activities. This paper presents 4 templates and 2 sample models for uEFL. The templates and models will show how learning activities can be integrated with business activities efficiently.

본 논문은 BPM(Business Process Model)에 룰(rule/policy)을 적용하여 3-Tier 구조의 BPM을 제안하고자 한다. 이는 비즈니스 프로세스를 효율적으로 관리하고, 빠르게 변화하는 업무를 비즈니스 프로세스 모델링하고 그에 필요한 응용 프로그램의 개발을 위해 BPM과 CBD(Component Based Development)간의 접목에 초점을 둔다. 이를 통해서 새로운 비즈니스 프로세스를 추가/변경 시, 필요한 응용업무 프로그램 개발 기간 단축을 할 수 있으리라 본다. 은행 비즈니스업무에 대해 비즈니스 프로세스 모델링을 적용 사례로 보여준다.

In this paper, low-power heart beat detection algorithm and structure is proposed. The proposed detection algorithm utilizes filter banks to display a specific beat per minute(BPM) from the heart beat signals. Since general filter banks need a lot of computation to calculate a BPM, we propose the filter banks structure using modified CIC(Cascaded Integrator Comb) filters. It is shown that the proposed modified CIC filter banks algorithm can display the BPM from the heart beat signals precisely and efficiently.
