Purpose: Dynamic Myofascial Release(DMFR) was conducted as it was expected to be effective improving body movements and Chronic Low Back Pain when the MFR and joint mobility were mobilized in a direct or indirect manner to approach the problematic area. Methods: 30 patients with non-specific low back pain were selected and randomly divided into DMFR group (N = 15) and control group (N = 15). The control group was received treatment with limited of trunk's ROM and DMFR group was received DMFR. Dynamic Myofascial Release is a separate therapeutic area from joint mobilization. Because Dynamic Myofascial Release is a therapeutic method for myofascial that is the connective tissue that connects the whole human body. And because the patient and the therapist are involved in the treatment at the same time, and the patient's active posture or participation includes low intensity movements that can be released only by breathing. The other is that the therapeutic action that causes movement around the fixed axis is extremely restrained as if it reminds of slow video and static energy therapy Results: The results showed that the mobility and standing balance of the trunk increased significantly compared to the control group (Lee Dong-woo et al, 2019). Dynamic Myofascial Release is expected to help improve trunk movement and non-specific low back pain, and should be used properly with Myofascial Release (P<.05) Conclusions: Dynamic Myofascial Release(DMFR) was effective. These of direct or indirect methods to access problematic areas, including MFR and joint mobility, was effective in improving body movements and lumbar pain.

Objectives : To observe the effect of acupuncture treatment in chronic shoulder pain patients. Methods : 36 voluntary patients were randomly assigned to an acupuncture treatment group(E GrouP, n=18) and a control group(C GrouP, n=18). The E Group patients received acupuncture treatment on LI_(15), TE_(14), GB_(21) and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for four weeks. The C Group patients received no treatment. All patients in both groups were instructed to practise self exercise in their daily lives. Evaluations were made at baseline and after four weeks of study. The Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI) and the patient's subjective pain was measured by Visual Analogue Scale(VAS). The obtained data was analyzed. Results '. The E Group showed significant(p<0.05) improvement in CSA, SPADI and VAS after four weeks of treatment. The C Group showed significant(p<0.05) improvement in CSA, but the change of SPADI and VAS was insignificant(P>0.05). CSA and SPADI of E Group significantly(p<0.05) improved compared to the C GrouP, but the difference of VAS change in the two groups was insignificant(p>0.05). Conclusions : Four weeks of acupuncture treatment significantly improved CSA, SPADI and VAS. The improvement of CSA and SPADI was significant(p<0.05) compared to untreated patients.

토양으로부터 분리한 Streptomyces 속 균주 HA-40이 생산하는 내열성 α-amylase의 효소학적 성질을 조사한 결과는 다음과 같다. 효소의 작용 최적 온도는 65℃였으며 activation energy 는 16.9Kcal/mole이었고 60℃에서는 안정하였으나 70℃에서는 30분 처리로 약 50%, 1시간 처리로 약 75%가 실활하였다. 그러나 ??를 0.1mM농도로 첨가한 경우엔 70℃ 에서 1시간 처리하여도 잔존활성도가 55%이상으로 열변성에 대한 ??의 보호효과가 있었다. 본 효소는 pH7에서 활성이 가장 강하였으며 안정성도 가장 높았다. 그리고 금속이온 중에서 ??의 첨가로 효소활성이 증대되었으며 ??, ??, ??등에 의해서 활성이 저해되었다. 각종 효소저해제는 대부분 영향을 미치지 못하였으나 EDTA가 반응액 중에 공존하면 효소활성이 강하게 저해되었다 본 효소는 maltotriose이하의 당류에 대해서는 분해력이 없었으며 amylose에 대한 환원당 생성력을 100으로 하였을때 soluble starch 108, amylopectin 94, glycogen 87, dextrin 48, potato starch 25, corn starch 18로 생전분에 대한 분해력은 soluble starch에 비해서 1/4∼1/5 정도밖에 되지 않았다. 그리고 soluble starch에 대한 Km 치는 1.9㎎/㎖였다. The properties of a thermostale α-amylase produced from Streptomyces sp. strain HA-40, isolated from soil, were investigated. The optimal temperature of the enzyme was 65℃ and the enzyme was stable below 60℃. However, at 70℃ about 75% of the activity was lost after 1hr treatment, but by the addition of ?? in the concentration of 0.1mM only 45% of the activity was lost. The enzyme was most active and stable at around pH 7. The activity of the enzyme was increased by the addition of ??, but depressed by ??, ??, and EDTA. The enzyme could be hydrolyze soluble starch, amylose, amylopectin and glycogen well, and could also digest dextrin and raw starch. The Km value for soluble starch was 1.9㎎/㎖.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain.

유한요소법을 이용한 환자별 교정시스템 구축의 기초 알고리즘 개발과 적용 : Development and Application of the Basic Algorithm

신정욱,남동석,김태우,이성재 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.5

본 연구는 최근 많은 연구가 행해지고 있는 유한요소를 이용한 교정시스템구축에 있어서 정상교합자가 아닌 부정교합 환자별 유한요소 모델구출을 위한 기초 알고리즘 개발에 그 목표가 있다. 기존에는 유한요소 분석을 위해서 한 환자의 치열을 유한요소 모델로 재현하고자 할때, 전처리 과정에 대부분의 시간을 소요해야만 했다. 본 연구에서는 이 전처리과정을 자동화할 수 있는 기초 알고리즘을 마련하여, 향후 이 방면의 연구를 용이하도록 하였다. 이를 위하여 임의로 선택된 부정교합 환자의 상하악 모형을 이용하여 치아의 삼차원적인 위치를 계측할 수 있는 표준화된 방법을 제시하였으며, 또한 본 연구를 통하여 개발된 프로그램을 이용하여 유한요소의 전처리과정을 자동화할 수 있는 기초을 마련하였다. 본 연구는 아래와 같은 단계를 거쳐 수행하였다. 1. 상, 하악 중절치에서 제2대구치까지 14개의 치아 형상을 상, 하악 각각 구축하여 개별 화일로 저장한다. 2. 이 치아에 standard bracket을 치관의 FA point와 bracket slot의 중앙이 일치되도록 부착한다. 3. 대상 환자의 석고 모형을 제작한다. 4. 석고 모형에서 본 연구를 위해 제작된 기구들로 치아의 crown inclination, angulation, 그리고 교합면에서 치관첨까지의 수직거리를 계측한다. 5. 표준화하여 촬영한 석고모형의 사진을 이용하여 화상처리기법으로 치아의 치열궁 형태를 파악한다. 또한 사진상에서 치아의 수평적 위치 및 회전량을 측정한다. 6. 계측된 crown inclination, angulation, 수직거리, 그리고 치열궁의 형태 미 치아의 회전정도 등을 회전행열을 이용하여 만든 프로그램에 입력한다. 이 프로그램은 유한요소 전처리 과정에 필요한 치아의 배열상태를 담고 있는 데이터를 결과파일로 제공하는데, 이 결과 파일은 일반적인 상용 유한요소 프로그램에서도 사용 가능하다. 7. 개개의 치아파일은 이 결과 파일에 따라 삼차원적인 위치로 배열되어 선택한 특정환자의 유한요소 모델을 완성하게 된다. 상기와 같은 여러 단계를 거친 후 임의로 선택한 부정교합자의 상, 하악 유한요소 모델구축을 위한 기초 자료를 구출할 수가 있었으며, 개개인 환자의 모형에서 얻은 정보로 유한요소 모델로 재현하기 위한 전처리과정의 기초 알고리즘을 마련하였다. The purpose of this study is to develop the basic algorithm for the finite element method modeling of individual malocclusions. Usually, a great deal of time is spent in preprocessing. To reduce the time required, we developed a standardized procedure for measuring the position of each tooth and a program to automatically preprocess. The following procedures were carried to complete this study. 1. Twenty-eight teeth morphologies were constructed three-dimensionally for the finite element analysis and saved as separate files. 2. Standard brackets were attached so that the FA points coincide with the center of the brackets. 3. The study model of a patient was made. 4. Using the study model, the crown inclination, angulation, and the vertical from the tip of a tooth was measured by using specially designed tools. 5. The arch form was determined from a picture of the model with an image processing technique. 6. The measured data were input as a rotational matrix. 7. The program provides an output file containing the necessary information about the three-dimensional position of teeth, which is applicable to several finite element programs commonly used. The program for a basic algorithm was made with Turbo-C and the subsequent outfile was applied to ANSYS. This standardized model measuring procedure and the program reduce the time required, especially for preprocessing and can be applied to other malocclusions easily.

The purpose of this study was to offer gymnasts data for successfully performing triple back somersault dismount(TBSD) and for designing training programs to progress gymnasts to the advanced dismount skills from the horizontal bar through comparative analysis of selected biomechanical factors of single back somersault dismount(SBSD), double back somersault dismount(DBSD) and TBSD. The subjects employed were a total of 4 male middle and high school gymnasts aged between 15 and 16 years. A motion-picture camera, fliming at a nominal rate of 54 frames/s, was used to record the performance of subjects on each trial. This camera was placed at a distance of 15 m from the inward pole of horizontal bar with its optical axis at right angle to this pole. The results obtained are summarized as follows: The mean release angle was 80.5° for the SBSD, 77.3° for the DBSD and 71.3° for TBSD. There were significant differences between the SBSD and the TBSD(p<0.01), the DBSD and the TBSD(p<0.05) but no significant difference between the SBSD and the DBSD. The angular velocity at release was 4.533 ㎭/s for the SBSD, 5.338 ㎭/s for the DBSD and 6.020 ㎭/s for the TBSD. There was a significant difference among these velocities(p<0.05, p<0.01). The linear velocity at release was 5.458m/s for the SBSD, 5.750m/s for the DBSD and 6.083m/s for the TBSD. In this case, we had a significant difference only between the SBSD and the other two somersaults(p<0.05, p<0.01). The shoulder angle at release was 170.5° for the SBSD, 167.0° for the DBSD and 154.3° for the TBSD. There were significant differences between the SBSD and the TBSD(p<0.05), the DBSD and the TBSD(p<0.05) but no significant difference between the DBSD and the TBSD. The hip and knee angle at release were increased respectively by increasing the number of somersault but showed no significant difference among these angles. The mean flight time from release to landing for each somersault was calculated; it took the subjects 1.315s to perform the SBSD, 1.345s to perform the DBSD and 1.416s to perform the TBSD. There was a significant difference among these somersaults with respect to time(p<0.05, p<0.01). The mean maximum height was 3,633m for the SBSD, 3,720m for the DBSD and 3,780m for the TBSD. There was a significant difference only between the SBSD and the other two somersaults. The mean horizontal distance was decreased respectively by increasing the number of somersault but showed no significant difference among these somersaults with respect to distance. The smallest hip angle during flight in the SBSD was 115.3° at 0.317s after the subject left the bar, for the DBSD it was 48.2° at 0.621s while that of the TBSD was 32.3° at 1,102s after release. The relationship between the time the smallest hip angle observed and the total flight time was determined; it took 24.1% of the total flight time of the SBSD to reach the smallest hip angle. In the DBSD, it took 46.2% of the total flight time to reach for the smallest hip angle and in the TBSD 77.8% of the total flight time to reach the smallest hip angle. From the above results, the gymnast would need to (1) increase angular velocity before release by manipulating of body shape, (2) change the release angle and (3) stay tuck position longer by shortening as quickly as possible the angle of each body joint to perform successfully the TBSD. Also to be able to perform quadruple back somersault dismount, a gymnast would need flight time of a minimum 1,782s.

申澈洙,姜宇政,李東勳 충주대 산업과학기술연구소 1994 産業科學論文集 Vol.2 No.-

This paper is to describe the design of the noise reduction of the axial flow fans. The nature and magnitude of the noise-producing mechanisms and the noise reduction are discussed on the basis of the results and theories published up to now. Sources of noise in axial fans can be classify into rotational and non-rotational noise. Rotational noise which is caused by inflow distortion and turbulence consists principally of tones related to the blade passage frequency. While, non-rotation noise which is caused by an interaction of the blade with the tip clearance vortex is broad band in character. The main parameters investigated for noise reduction in axial fans are as follows ; tip clearance, number of blade, chord length, camber angle, solidty, blade thickness, twisting angle, serrations attached on the blade, rotating shroud attached on the tip blade tip, bellmouth, etc.
