Objectives : The purpose of this study was to assess the use of Korean medicine for treating radial nerve palsy. Methods : We searched for studies on the use of Korean medicine for the treatment of radial nerve palsy in 7 electronic databases and analyzed these studies. Results : We found 95 studies on radial nerve palsy from 7 electronic databases. We excluded 77 duplicate studies, 1 review article and 2 studies published before 2000. As a result, 15 case studies(36 patients) were included. Acupuncture(15 times), electroacupuncture(6 times), pharmacopuncture(9 times), herbal medicine(11 times), physical therapy(10 times), moxibustion(3 times), cupping therapy(1 time), chuna manual therapy(1 time) and yinyang balancing appliance(1 time) were used. LI11 for acupuncture, LI4, LI11 for electroacupuncture, bee venom as pharmacopuncture material and LI4, LI10, LI11 in pharmacopuncture point, Boik-tang gami as herbal medicine, hot pack for physical therapy, LI4, LI11 for moxibustion were the most frequently used. Conclusions : Korean medicine treatment for radial nerve palsy has been performed in various ways. However, we found limited evidence regarding Korean medicine for radial nerve palsy. Thus, we think various types of studies including more case reports, for radial nerve palsy should be performed in the future.

Vehicle steering system determines the direction of a vehicle. A manual steering system consists of mechanical connections between the steering wheel and tires. Recent power steering system adds an actuator to help a driver to steer easily at low speed. However, at front collision, the driver can be injured by steering shaft and the power steering pump decreases the engine power. To solve these problems, electronic power steering system which connects the steering wheel and tires with electronic connection is proposed, that has advantages such as decrease of engine load and increase of driver safety reactive. Since the ratio between driver's steering torque and steering torque of tires can be controlled freely, the torque which is delivered from the road to the driver through tires and steering wheel can be reshaped to make the driver feel comfortable. In this paper, the ratio of delivering steering torque and the magnitude of force to be delivered from road to driver has been controlled using fuzzy controller, and it's effectiveness has been shown through simulation results.

Nowadays the Rational Function Model (RFM), an abstract sensor model, is substituting physical sensor models for highly complicated imaging geometry. But RFM is algorithm to be required many Ground Control Points (GCP). In case of RFM of the third order, At least forty GCP are required far RFM generation. The purpose of this study is to research more efficient algorithm on GCP and accurate algorithm similar to RFM. The Polynomial Camera Model is relatively accurate and requires a little GCP in comparisons of RFM. This paper introduces how to generate Polynomial Camera Model and fundamental algorithms for construction of 3-D topographic data using the Polynomial Camera Model information in the Kompsat stereo pair and describes how to generate the 3-D ground coordinates by manual matching. Finally we tried to extract height information for the whole image area with the stereo matching technique based on the correlation.

The power control system of Smart UAV is similar to the propeller pitch governing concept of turboprop aircraft. The pilot inputs the engine power directly and the pitch governor controls the propeller pitch to maintain the propeller RPM. The manual back-up system of PW206C engine is used for the engine power control of Smart UAV. Engine performance estimation program is used to predict the control range of power lever arm(PLA) angle according to the variation of flight altitude and speed. These data provide a guide for the engine control in manual mode operation.

The power control system of Smart UAV is similar to the propeller pitch governing concept of turboprop aircraft. The pilot adjusts the engine power directly and the pitch governor controls the propeller pitch to maintain the propeller rotational speed. The electronic engine controller(EEC) of PW206C engine developed for helicopter is not fit for the power control concept of Smart UAV, and therefore the manual back-up system of PW206C engine is used for the engine power control of Smart UAV. Engine performance estimation program is used to predict the control range of power lever angle(PLA) according to the variation of engine output shaft speed, flight altitude and flight speed. These data provide a guide for the PLA control in manual mode operation.

Objectives The purpose of this study is to provide an evidence base for the effectiveness of Chuna manual therapy (CMT) alone for cervicogenic dizziness. Methods We conducted a search up to October 2018 in 7 electronic databases. The randomized controlled trials (RCTs) that performed CMT for cervicogenic dizziness were included. The risk of bias was assessed using the Cochrane risk of bias tool. Results Ten RCTs met the inclusion criteria. The meta-analysis of 4 RCTs showed favorable results for the use of CMT alone compared to medication. Conclusions In 10 RCTs, we found that CMT was effective in cervicogenic dizziness. However, most of the included RCTs were unclear risk of bias. Therefore, well designed RCTs would be needed to obtain the stronger evidence level of CMT for cervicogenic dizziness.

Objectives The purpose of this study is to analyze the trend and indication of clinical research about Visceral Chuna Manipulation and to suggest the direction of further study. Methods We searched 9 electronic databases (MEDLINE Pubmed, EMBASE, CENTRAL, CiNii, CNKI, KMbase, OASIS, NDSL, KISS) using the search terms "visceral manipulation", "visceral manual therapy" and identified relevant literature that investigated visceral manipulation as a intervention for various subjects. Results Among 142 studies were searched and screened, 16 met designated criteria. Visceral Chuna Manipulation showed the effectiveness in musculoskeletal disease, digestive disease, psychiatry, obstetrics, circulatory and oncology. Conclusions This study shows possibility of Visceral Chuna Manipulation as a treatment for many diseases. Better designed further study is necessary to establish the evidence of clinical efficacy of visceral manipulation and to suggest standard of techniques and treatment protocols for diverse patients.

Bluetooth technology(BT) is a standard for short distance wireless communication and widely used to connect and control various electronic and telecommunication devices without wires, where CSR8670 chip is generally adopted. These BT devices are required to comply with BT specification and the equipments for conformance test are also important. However, the existing BT testing methods have inconvenience in that they are mostly time-consuming procedure due to not only repetitive execution for each evaluation element but also error-prone nature of manual experiments. This paper proposes an automated BT communication test method using CSR8670 chip, which solves the problems related to manual testing methods. The proposed method can reduce the development period of BT products and guarantee the quality improvement owing to the exact system error detection capability.

The military services have sought to improve the overall quality, management, and delivery of military technical information in all of its aspects. The efforts concentrated on developing IETM(Interactive Electronic Technical Manual) by using the application of computer technology for the storage, control, and presentation of maintenance, system-operation, training, and other forms of logistic-support technical information. In this paper, the methodologies are presented to evaluate the operational effectiveness of IETM which consists of confirmity and performance. Confirmity is evaluated by the check-sheet based on the standard of CALS, and performance by the comparison of the technician performance between IETM and paper-TM.
