Purpose: The aim of the study was to examine the effect of auricular acupressure on low back pain and headaches in nurses. Methods: A open-label randomized controlled trial was used. Thirty-nine nurses with low back pain for more than 3 months participated in this study. Auricular acupressure stickers were applied to the participants's waist, head and Shen men in the experimental group for 2 weeks. The Numeric Rating Scale (NRS), the Visual Analog Scale (VAS), and the Headache Impact Test-6 (HIT-6) were administered to measure participants' pain. Results: The mean differences of the VAS and the HIT-6 were significant in the experimental group at the pre and post-tests. A repeated-measures ANOVA revealed that low back pain and headache measured using NRS in the experimental group decreased significantly compared to the control group at the pre and post-tests over 2 weeks. Conclusion: The results of this study indicated that auricular acupressure could be used as a useful intervention for self-care for nurses with low back pain and headache.

The four wing unmanned aerial vehicle owns the characteristics of small size, light weight, convenient operation and well stability. But it is easily disturbed by external environmental factors during flight with these disadvantages of short endurance and poor attitude solving ability. For solving these problems, a microprocessor based on STM32 chip is designed and the overall development is completed by the resources such as built-in timer and multi-function mode general-purpose input/output provided by the master micro controller unit, together with radio receiver, attitude meter, barometer, electronic speed control and other devices. The unmanned aerial vehicle can be remotely controlled and send radio waves to its corresponding receiver, control the analog level change of its corresponding channel pins. The master control chip can analyze and process the data to send multiple sets pulse signals of pulse width modulation to each electronic speed control. Then the electronic speed control will transform different pulse signals into different sizes of current value to drive the motor located in each direction of the frame to generate different rotational speed and generate lift force. To control the body of the unmanned aerial vehicle, so as to achieve the operator's requirements for attitude control, the PID controller based on Kalman filter is used to achieve quick response time and control accuracy. Test results show that the design is feasible.

Objective: This case report outlines an investigation into the efficacy of Korean medicine treatment in a patient who presented with acute cholangitis accompanying common bile duct stones. The patient underwent percutaneous transhepatic gallbladder drainage and subsequently experienced resolution of the common bile duct stones. Methods: The patient was treated with Shihosogan-tang, general acupuncture, ear acupuncture, moxibustion, and cupping therapy. Changes in symptoms were evaluated using a self-reported numerical rating scale (NRS) score and a visual analog scale (VAS) score each morning. Laboratory tests were conducted to examine serum amylase, serum lipase, and liver function. Results: After 29 days, the NRS scores for indigestion and fatigue and the VAS score for abdominal pain all decreased. Additionally, the laboratory test results showed improvement. Discussion: The results suggest that Korean medicine could be effective in treating symptoms of acute cholangitis. However, further research is necessary.

Background: Standard open acromioclavicular (AC) stabilization is associated with increased postoperative complications including deltoid injury, infection, tunnel complications, loss of reduction, and wound/cosmetic concerns. Arthroscopy may offer superior visualization and advantages that limit these risks. The aim of this prospective non-randomized study is to evaluate advantages and long-term reliability of arthroscopic AC stabilization. Methods: Thirty-two patients with acute grade III, IV and V AC dislocations underwent arthroscopic AC reconstruction with long-term assessment by clinical AC examination, Simple Shoulder Test, American Shoulder and Elbow Surgeons scores, visual analog scale, Specific AC Score and Quick Disabilities of the Arm, Shoulder and Hand scores. Radiographs verified conservation of initial reduction and presence of coracoclavicular (CC) ossifications. Complications, revision rate, and satisfaction were assessed and compared to the literature. Results: Mean follow-up time was 67.6 months. All clinical outcome scores improved and differences were statistically significant (P<0.001). Initial postoperative radiographs consistently showed complete reduction. Two patients experienced relapse to grade II AC dislocation without clinical implications. In total, 71.8% showed CC ossifications without functional impairment, and in 31.3% concomitant injuries were observed. Reintervention rate was 9.4%, and 96.9% of patients were satisfied with procedure outcomes. Conclusions: Arthroscopic stabilization for acute AC joint dislocations offers satisfactory clinical and radiographic outcomes, and our results show that the arthroscopic technique is reliable in the long run. We report better reduction in maintenance, fewer complications, and similar reoperation rates compared to other techniques.

The purpose of this research was to determine whether or not a education program of low back pain would have benificial effect on nurses. Nonequivalent control group pre-post test research was designed. Subjects for this study were 50 selected from nurses who work at a general hospital in Taegu. Of them, twenty seven were assigned to experimental group, twenty-three to control group. The data were collected during the period from June 27 to August 31, 1994. The instruments used in this study were Visual Analog Scale for low back pain, Sit-and-reach test for trunk flexibility, and 1 min sit up test for abdominal muscle endurance. Data related to general chracteristics and factors of low back pain were collected with questionnaire developed by this reseacher. The data were analyzed by $X^2-test$, t-test and paired t-test, using the SAS package program. The results of this study are summerized as follows : 1. The numbers of the experimental group with low back pain were not a statistically significant difference from pre to posttesting($X^2=0.77$, p=.379), and the numbers of the control group with low back pain were also not a statistically significant difference from pre to posttesting($X^2=0.09$, p=.767). 2. The severity of low back pain of the experimental group was not a statistically significant difference from pre to posttesting(t=-0.55, p=.5857), and the severity of low back pain of the control group was also not a statistically significant difference from pre to posttesting(t=-0.70, p=.3101). 3. The trunk flexibility of the experimental group was not a statistically significant difference from pre to posttesting(t= 1.08, p=.2835), and the control group's trunk flexibility was also not a statistically significant difference from pre to posttesting(t=0.85, p=.4026). 4. The abdominal muscle endurance of the experimental group was a statistically significant difference from pre to posttesting(t=-2.42, p=.0190), but the control group's abdominal muscle endurance was not a statistically significant difference from pre to posttesting(t=-0.06, p=.9556) This study suggest that replication of study with more sample and more rigid treatment should be needed. And furthermore, the longitudinal research is needed to determine the effectiveness of education program.

The dynamometers which had made in a long time ago could not control the input/output quantity of water minutely and was sensitive to a noise since it was controlled by an analog control method. Therefore, a fully digital controlled system was urgently required to be robust against various noises. In this paper, the new system which can control the amount of circulated water in dynamometer was developed. This system is consisted of an industrial digital type controller and a servo motor. The industrial PLC was used as a main controller for the developed system, and the actuator and servo motor were used to control the inlet and outlet valve independently. The torque signal of load cell was fed back to the main controller to regulate the diesel engines load. Generally, an input/output valve position of the old dynamometer was fixed with a proper situation for an engine output test and the torque was changed according to the time interval. However, the torque value for the dynamometer could not be constantly kept because of the variation of the input water flow and fluid characteristic. Therefore, the automatic control of an inlet and outlet valve should be performed to keep the constant torque. So, the PID control method was applied to solve this problem. Also, the development of a web-based remote control system was described in this paper. This software will give us the convenience of operation, the more efficient operations, and the reduced operator workload for operation of the dynamometer. The application results of the system have been verified at actual diesel engine field.
