The purpose of this study is to help understand the pressure pain threshold's comparison following time progress after IMS to the trigger point and recognize this methode' effect for treating these kind of myofascial pain syndrome in clinic. Resently, myofascial pain syndrome is a disease that keeps the highest rate of patients visiting the Department of Rehabilitation Medicine. and so one should understand the change of IMS'effect following time progress for patients to be dealt rightly in clinic. In addition, the theory and treatment of myofascial pain syndrome needs to be understood or to be dealt rightly for therapists to treat and to approach to the right moment in right mode for the patients with myofascial pain syndrome. Therefore, one should know where to stimulate and why one stimulate trigger point and what effect one obtain after IMS.

The Purpose of this writing is a presentation of small turbine efficiency measuring method, applicable new technology, and several analysis result for real turbine. Measurement methods of hydraulic efficiency written in here are extracted from small turbine applicable international code(IEC, ASME). It includes brief synopsis of 'Current meter method' and 4 other methods and ASFM as a new small turbine applicable technology. And several analysis of test result are for recently performed domestic small turbine result in korea. Through this presentation of extracted code, I hope that it make other small turbine concerner be familiar to perform an efficiency test. for small turbine. And, some analysis of that, make other to feel the importance of efficiency test.

Purpose : The purpose of this study was to find the effect of foot bath on blood pressure(BP) following treadmill exercise. Methode : Subject of study were forty healthy males without any cardiovascular, musculoskeletal, and neurologic diseases. Following twenty minutes walking at a speed of 5m/s on the treadmill, ten twenty subjects in experimental group received foot bath, on the dominant lower limb while sitting in chair. Foot bath was applied to the level of the lateral and medial malleoli keeping the temperature of the paraffin bath at $40{\pm}0.5^{\circ}C$. Twenty subjects in control group took a rest sitting in chair in a comfortable position. BP was measured in right brachial artery. BP was measured five times(before exercise, immediately after exercise, 5 minutes, 10 minutes, and fifteen minutes after exercise). Results : The study showed that for diastolic blood pressure, there was no significant difference between the experimental and the control group. However, systolic blood pressure(SBP) increased significantly after exercise compared with SBP before exercise (p<.05). In addition, SBP in five minutes after exercise decreased significantly compared with SBP in immediately after exercise (p<.05). On the other hand, the control group had significant difference between SBP measured before exercise and SBP measured at the other measure time (p<.05). In five minutes after exercise, SBP in experimental group had significant difference with SBP in control group (p<.05). Similarly, in ten and fifteen minutes after exercise, SBP in experimental group had significantly difference with SBP in control group (p<.05). Conclusion : Consequently it was confirmed that when foot bath was applied, the increased BP induced by the exercise returned to normal range rapidly.

In this study, the 2-step methode by ALD equipment was used to improve the characteristics of ZnO thin films used in a piezoelectric layer when the FBAR devices of a SMR type are fabricated. The Height of formed buffer layer was $400{\AA}$ and ZnO thin film of $13600{\AA}$ was deposited by RF sputter on the buffer layer. When ZnO thin films are deposited, deposition conditions such as pressure, injection time of source and purge time were changed variously. The characteristics of piezoelectric layer such as a crystal orientation and micro-structure of deposited ZnO thin films were studied by SEM, AFM and XRD.

The work function of Ag (silver) is too low (~4.3 eV) to be used as an electrode of T-OLED (Top Emission Organic Light Emitting Diode). To solve this weakness, researches used plasma-, UV-, or thermal treatment on Ag films in order to increase the work function (~5.0 eV). So, most of studies have focused only on the work function of various treated Ag films, but studies focusing on nanomechanical properties were very important to investigate the efficiency and life time of T-OLED etc. In this paper, we focused on the mechanical properties of the Ag and $AgO_x$ film. The Ag was deposited on a glass substrate with the thickness of 150 nm by using rf-magnetron sputter with the power was fixed at 100 W and working pressure was 3 mTorr. The deposited Ag film was UV treated by UV lamp for several minutes (0~9 min). We measured the sheet resistance and mechanical property of the deposited film. From the experimental result, there were some differences of the sheet resistance and surface hardness of Ag thin film between short time (0~3 min) and long time UV treatment. These result presumed that the induced stress was taken place by the surface oxidation after UV treatment.
