Objective To investigate and demonstrate persistent increase of peak cough flow after mechanical in-exsufflator application, in patients with neuromuscular diseases and pneumonia. Methods A mechanical in-exsufflator was applied with patients in an upright or semi-upright sitting position (pressure setting, +40 and $-40cmH_2O$; in-exsufflation times, 2-3 and 1-2 seconds, respectively). Patients underwent five cycles, with 20-30 second intervals to prevent hyperventilation. Peak cough flow without and with assistive maneuvers, was evaluated before, and 15 and 45 minutes after mechanical in-exsufflator application. Results Peak cough flow was 92.6 L/min at baseline, and 100.4 and 100.7 L/min at 15 and 45 minutes after mechanical in-exsufflator application, respectively. Assisted peak cough flow at baseline, 15 minutes, and 45 minutes after mechanical in-exsufflator application was 170.7, 179.3, and 184.1 L/min, respectively. While peak cough flow and assisted peak cough flow increased significantly at 15 minutes after mechanical in-exsufflator application compared with baseline (p=0.030 and p=0.016), no statistical difference was observed between 15 and 45 minutes. Conclusion Increased peak cough flow after mechanical in-exsufflator application persists for at least 45 minutes.

The purpose of this study is to develop a cancer rehabilitation program for cancer survivors in the form of a smartphone application and to confirm the effectiveness through Pilot study. The contents of the application consisted of health records, lab-test records, and health information, and the information recorded by the patient was graphically checked for changes over time on my page. 7 subjects who ended acute treatment and were undergoing follow-up were asked to use the application for 4 weeks, and then changes in variables (uncertainty, e-health literacy, self-efficacy, and cancer rehabilitation) were confirmed. It was confirmed that e-health literacy and self-efficiency increased significantly over time after using the application. In addition, the level of cancer rehabilitation was found to increase significantly over time. The application for cancer rehabilitation developed in this study needs to be expanded to improve the quality of life of cancer survivors.

Purpose : The study was aimed to evaluate the improvement of cognitive and hand functions after the application of a complex rehabilitation intervention program on patients with mild cognitive impairment (MCI) and dementia who were living a regional community from. Methods : Subjects who were living in a regional sanatorium or who were outpatients of a community health center were enrolled from 2012. 2 to 2013.2 All subjects were enforced 8 cycles of a complex rehabilitation intervention program including RON dance, physical activity using therabands, reality awareness training, space retrieval training and handicraft activities. Results : There were significant improvement in LOTCA-G cognitive function and JTHFT hand function test after the application of a complex rehabilitation intervention program. Conclusion : The result shows a significant improvement in cognitive and hand functions after the application of a complex rehabilitation intervention program in patients with MCI and dementia. Therefore the authors suggest the vast studies of the cognitive function program development and hand function vitalization by the application of a complex rehabilitation intervention program.

Purpose: The focus of this research was a systematic review of published articles and theses for a degree in Korea and foreign countries on rehabilitation therapy for patients with total knee arthroplasty (TKA). Methods: The literature until December in 2011 were searched and the data basis included Medline, CINAHL, KERIS, National Library of Korea, and National Assembly Library web sites. Words for the search were TKA or TKA and rehabilitation. Studies included randomized controlled and non-equivalent control group pretest-posttest design. 31 studies were analyzed focusing on type, application method, dependant variable and effect using descriptive statistics. Results: Seventeen rehabilitation therapies and forty-nine dependant variables were used. The application methods of rehabilitation therapy were diverse. The most frequently used rehabilitation type was an exercise therapy and a pain/discomfort was the most frequently used dependant variable. The effects of rehabilitation therapy were inconsistent. Conclusion: The individualized rehabilitation therapy must be comprised of type, time, frequency, period and duration. Attention must be made as to the research design, especially the better measurement of the dependent variables. This review may serve as a base for future research.

Recently computer graphic technology has achieved remarkable development. Applications of this technology to various fields are expected. In this study, one application of computer graphics to the medical field is shown. We developed a rehabilitation system of hand manipulation using virtual reality aiming to offer enjoyable rehabilitation training to physically handicapped people with upper limb disabilities. This rehabilitation system generates training environments for upper limbs, such as moving balls in virtual space of computer. And by using data glove as a sophisticated input device, a user can manipulate objects in virtual space by his hand. By using this rehabilitation system, a user can have rehabilitation training under various conditions without feeling tedious.

Recently, the demand on the practical application of life-cycle cost effective design and rehabilitation of bridges is rapidly growing in civil engineering practice. However, in spite of impressive progress in the researches on the Life-Cycle Cost (LCC), the most researches have only focused on the theoretical point but did not fully incorporate the critical issues for the practical implementation. Thus, this paper is intended to suggest a systemic integrated approach to the practical application of various LCC methodologies for the design and rehabilitation of bridges, For that purpose, hierarchical definitions of LCC models are presented to categorize the approach of LCC assessment applicable for the practical implementation. And then, an integrated LCC system model is introduced with an emphasis on data uncertainty assessment and user-friendly knowledge-based database for its successful implementation. Finally, in order to demonstrate the LCC effectiveness for design and rehabilitation of real bridge structures, illustrative examples are discussed.

The aim of this study was to investigate the effects of TENS and cold application on secondary thermal hyperalgesia in rats induced by muscle pain. Muscle pain was induced in male Sprague-Dowley rats by intra-muscular injection of gastrocnemius with $3\%$ carrageenan. The paw withdrawal latency(PWL) and tail flick test(TFT) to heat were used to detect secodary thermal hyperalgesia induced by the muscle pain. PWL and TFT were quantified before and 4, 10, and 24 h after induction of muscle pain and after application of TENS(100Hz, $100{\mu}s$, sensory intensity) and cold($4^{\circ}C$). TENS and cold significantly reduced the PWL and TFT to heat stimuli when compared with controls receiving no TENS and cold(p<.05). These results suggested that application of TENS and cold attributed to decrease secodary thermal hyperalgesia in rat induced by muscle pain.

본 연구(II)는 연구(I)에서 제안한 상수관로의 노후도 예측에 근거한 최적 개량 모형을 A시를 대상으로 이를 적용하였다. 노후도 예측 모형은 굴착 및 실험이 필요한 14개 항목과 굴착 및 실험이 필요하지 않은 9개 항목을 구분하여 각각 관의 노후도 등급을 산정하였다. 노후도 예측 모형 적용 결과 항목개수에 따른 등급의 차는 l~2% 이내로 굴착 및 실험을 하지 않고도 노후도 예측이 가능한 것으로 나타났다. 최적 개량 모형은 노후도 항목별 최대 잔존수명과 제약조건 유무로 구분하여 적용하였다. 적용결과 항목별 최대 잔존수명의 증가에 따라 개량 시기 및 비용이 증가하였다. 또한 예산제약을 제외한 모형과 비교해서 예산제약을 고려한 모형이 모든 항목에서 비용이 증가되었다. 이는 예산제약을 고려할 경우 실제 주어진 최대 잔존수명 기간이내 매년 발생하는 예산의 최대 금액을 넘지 않은 대신에 매년 비슷한 비용으로 개량을 실시하기 때문인 것으로 판단되었다.
