Objectives : This study reports the clinical effects of miniscalpel needle therapy in patients with carpal tunnel or tarsal tunnel syndrome. Methods : Three patients with carpal tunnel syndrome (CTS) or tarsal tunnel syndrome (TTS) (first case, patient with CTS and TTS; second case, patient with CTS; and third case, patient with TTS) were treated with miniscalpel needle (MSN) therapy and integrative Korean medical treatment. The Numeric Rating Scale (NRS), Neuropathic Pain Scale (NPS), Boston scale score, and AOFAS (American Orthopaedic Foot and Ankle Society) ankle-hindfoot score were measured. Results : In general, outcome measures after treatment showed improvement in all cases. In the first case (CTS and TTS), scores on the NRS, NPS, and Boston scale decreased, and AOFAS ankle-hind foot scores increased. In addition, Tinel's sign showed improvement. In the second case (CTS), scores on the NRS, NPS, and Boston scale, and Tinel's sign, were decreased. In the third case (TTS), scores on the NRS and NPS, and Tinel's sign, showed improvement, and AOFAS ankle-hind foot scores were increased. Conclusion : These results suggest that MSN therapy has a meaningful clinical effect in CTS and TTS.

Background: This study was conducted to investigate the effects of mechanical traction therapy on pain, symptom severity, and functional status in patients with carpal tunnel syndrome. Design: Randomized controlled trial study. Methods: The 24 participants in this study were randomly assigned to either the Mechanical traction therapy (MTT) group (n=12) or the placebo group (n=12). Both groups performed tendon and neural gliding exercise. Both groups underwent mechanical traction therapy with their forearms placed on a traction device. However, in the placebo group, the device was turned off, and a placebo treatment was administered without any mechanical stimulation. All the participants underwent 18 sessions of intervention (10 minutes, 3 days per week for 6 weeks). Both groups were assessed for pain using the numerical pain rating scale and for symptom severity and functional status using the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ), which includes two additional scales: the Boston Symptom Severity Scale (BSSS) and the Boston Functional Status Scale (BFSS). Results: The muscle activation, pain, symptom severity, and functional status in the MTT group were significantly improved compared to the placebo group (p<0.05). Conclusion: The results of this study indicate that traction therapy combined with tendon and neural gliding exercise. are a beneficial method for improving pain, symptom severity, and functional status in patients with carpal tunnel syndrome.

In this Paper, the effect of stage ceiling height on the acoustic characteristics of rectangular concert halls are investigated. To find out the acoustic properties of audience area, A simple Boston Symphony Hall(BSH) model which is typically rectangular shaped was applied for computer simulation. A newly built rectangular concert hall with 400 seats was also chosen for a scale model $(1.2m{\times}0.68m{\times}0.31m)$ study and its computer simulation varing the stage ceiling height and the volume. The results show that RT increased as the stage ceiling was lowered and the difference rate of RT by its variance is from -0.09 to -0.06[sec/m].

This study investigates the effect of geometrical shape of concert halls, with variation in the shape and location of diffusers. The acoustical characteristics both in the audience area and on the stage 1:50 scale models of shoebox and fan-shaped halls. It was found that the front side walls affect sound diffusion. The 1:50 scale model based on the Boston Symphony Hall was used for monaural impulse response measurements for calculation of RT, EDT, C80, G and ST1. In addition, calculating the numbers and amplitudes of reflection rays were applied to quantify diffusion phenomena.

The aim of this report was to show the effects of acupotomy in patients with carpal tunnel syndrome. Four patients were treated with acupotomy twice. Visual analogue scale (VAS), Tinel's sign, Phalen's test, Boston carpal tunnel syndrome questionnaire (BCTQ), muscular strength test, and a cross-sectional area of median nerve was measured using ultrasound before and after treatment. In all 4 cases, the VAS score, BCTQ score and cross-sectional area of median nerve, all decreased and muscular strength test score increased. Tinel's sign and the Phalen's test changed from a positive to a negative in most cases. This report shows that acupotomy is an effective treatment for carpal tunnel syndrome. Further larger are needed to fully evaluate the beneficial effects of this treatment.

On this study, we extracted pending problem and controversial point from management of disaster such as terror for domestic massive performance and then, investigated countermeasure plan against disaster for massive performance through comparison and analysis between anti-disaster strategy of Korea and U.S. U.S are conducting security system actively for passenger of major facilities such as public institution. Nonetheless, In U.S that has the world's best security system, serious affair such as 911 terror and Boston marathon terror are continued to happen. When considering domestic situation that North Korea and South Korea are antagonistic to each other, it is judged when it is high time to prepare for threat of terrorism. Accordingly, On this study, through analyzing of latest terror attacks in U.S and disaster risk in the nation, we analyzed in detail countermeasure plan classified as legislation, operation of security system, instilling a sense. As the result of this analyzing, using by flow-chart, we suggested domestic optimized disaster management system for massive performance. Consequently, we propose to establish systematized disaster management system such as preliminary survey of disaster influence for massive performance.

Purpose: The aim of this study was to test the validity and reliability of the Korean version of the Quality of Nursing Work Life (QNWL-K) scale. The scale measures the reported quality of the nurse' work life among Korean nurses. Methods: The QNWL-K was developed through forward-backward translation techniques. An internal consistency reliability and construct validity using exploratory analysis were conducted using SPSS/WIN (21.0). Survey data were collected from 309 nurses who worked in two tertiary hospitals, four general hospitals, and two hospitals in Seoul and Gyeonggi, South Korea. Results: Factor analysis results of the revised QWNL-K demonstrated that it has a four-factor structure (work context, support systems for home/work life, work design, and staffing) that supports construct validity. Factor loadings of the 36 items ranged from .30~.77. The QNWL-K showed reliable internal consistency from Cronbach's ${\alpha}$ for the total scale of .93. Conclusion: The findings support that the QNWL-K has satisfactory construct validity and is a reliable measure of nursing work life in Korea.

This paper describes a novel MEMS integration technique on a CMOS chip. MEMS integration on CMOS circuit has many advantages in view of manufacturing cost and reliability. The surface topography of a CMOS chip from a commercial foundry has 0.9 ${\mu}{\textrm}{m}$ bumps due to the conformal coating on aluminum interconnect patterns, which are used for addressing each MEMS element individually. Therefore, it is necessary to achieve a flat mirror-like CMOS chip fer the microelectromechanical system (MEMS) such as micro mirror array. Such CMOS chip needs an additional thickness of the dielectric passivation layer to ease the subsequent planarization process. To overcome a temperature limit from the aluminum thermal degradation, this study uses RF sputtering of silicon nitride at low temperature and then polishes the CMOS chip together with the surrounding dummy pieces to define a polishing plane. Planarization reduces 0.9 ${\mu}{\textrm}{m}$ of the bumps to less than 25 nm.

Objective: Carpal tunnel syndrome is one of the most common upper extremity compressive nerve disorders in modern people. Various conservative treatments such as taping, exercise, and electrotherapy have been applied to carpal tunnel syndrome and their effectiveness has been proven. This study aims to determine whether home exercise combined with taping is effective for pain and functional disability in patients with carpal tunnel syndrome. Design: Randomized controlled study Methods: 21 patients were recruited and were randomly divided into HEx+T (Home exercise+taping) group (n=10) and HEx (Home exercise) group (n=11). All participants performed Home exercise(tendon and neural gliding exercise) 5 times a week for 6 weeks. Additionally, subject in the HEx group, taping was applied over the wrist and forearm during the training period. Wrist pain was measured by VAS (Visual Analogue Scale). Functional disability was measured using a BCTSQ(The Boston Carpal Tunnel Syndrome Questionnaire). Results: Both the HEx+T group and the HEx group showed a significant improvement in wrist pain(p<0.05), and the HEx+T group showed a more significant decrease in pain than the HEx group(p<0.05). There was a significant improvement in both groups in functional disability (p<0.05), and the HEX+T group showed more improvement than the HEX group(p<0.05). Conclusions: This study suggests that home exercise combined with taping is effective for pain and functional disability in patients with carpal tunnel syndrome.
