Trade can be greatly influenced by the change of international trade environment due to the characteristics of remote transactions. Furthermore, in the circumstance of emphasizing the national security again, the importance of the risk management of special materials has been increasing. As it was noted at Chapter 4, significant results such as the threat of enterprises' sustainable growth can be occurred when companies are related to the unlawful export of strategic materials or experience discouragement of export of main products. As the decision of strategic materials greatly depend on a specialized knowledge there is a possibility of misjudgement of strategic materials in terms of ordinary companies which is not accustomed to them. Furthermore risk management is more difficult due to the inclusion to the items of export license. To prepare such a risk of export of strategic materials, firstly, it should be checked to find whether counter traders are working in the industry which is not related to the spread of weapons of mass destruction, secondly, an appropriate process shall be designed and operated for products to be safely delivered to the trade counter. Therefore, our export enterprises have to introduce CP(Compliance Program), AEO or ISO28000 considering suitability for their actual situations not only to promote export and but also to avoid risk of export control and additional expenses. Through these appropriate processes, an efficient and effective management of the trade risk of strategic materials can be accomplished.

Banks are the engines that drive the operations in financial sector, money markets and growth of economy. With growing banking industry in India, frauds in Banks are increasing and fraudsters are becoming more sophisticated and ingenious. Shockingly, banking industry in India dubs rising fraud as "an inevitable cost of doing business." As part of study, a questionnaire-based survey was conducted in 2012-13 among 345 Bank employees "to know their perception towards bank frauds and evaluate factors that influence the degree of their compliance level." The study reveals, "there are poor employment practices and lack of effective employee training; usually over-burdened staff, weak internal control systems, and low compliance levels on the part of Bank Managers, Offices and Clerks. Although banks cannot be 100% secure against unknown threats, a certain level of preparedness can go a long way in countering fraud risk. Internal audit professionals should play an integral role in organization's fraud-fighting efforts. Some other promising steps are: educate customers about fraud prevention, make application of laws more stringent, leverage the power of data analysis technologies, follow fraud mitigation best practices, and employ multipoint scrutiny.

Objective : The purpose of this study is to review a case of hypertension. The patient was 41 years, a male. We stabilized blood pressure after administration of Daehuanghuanglianxiexin-tang. In this paper, we review the interpretation of Shanghanlun by analyzing the patient's progress, diagnosis, treatment. Methods : Blood pressure changes have been monitored during the period. Additionally, We have observed the patients' compliance and accompanied symptom by the timeline analysis. Results : According to Shanghanlun disease pattern identification diagnostic system, Wediagnosed a Greater yang disease. The patient was treated with Daehuanghuanglianxiexin-tang for 2 months. Daehuanghuanglianxiexin-tang was able to control blood pressure to under 120mmhg / 80mmhg. During the treatment period, the accompanied symptom Stiffness and pain in posterior neck has improved, patient's compliance was good, and symptoms improved without significant complication Conclusions : Taking of the Daehuanghuanglianxiexin-tang makes patient's blood pressure controlled to safe and stable range and eases the discomfort of posterior neck pain.

The growth of pulsed electromagnetic field (PEMF) therapy and its progress over the years for use in post-operative bone growth has been revolutionary in its effect on bone tissue proliferation and vascular flow. However, further progress in PEMF therapy has been difficult due to lack of more evidence-based understanding of its mechanism of action. Our objective was to review the current understanding of bone growth physiology, the mechanism of PEMF therapy action along with its application in spinal surgery and associated outcomes. The authors of this review examined multiple controlled, comparative, and cohort studies to compare fusion rates of patients undergoing PEMF stimulation. Examining spinal fusion rates, a rounded comparison of post-fusion outcomes with and without bone stimulator was performed. Results showed that postoperative spinal surgery PEMF stimulation had higher rates of fusion than control groups. Though PEMF therapy was proven more effective, multiple factors contributed to difficulty in patient compliance for use. Extended timeframe of treatment and cost of treatment were the main obstacles to full compliance. This review showed that PEMF therapy presented an increased rate of recovery in patients, supporting the use of these devices as an effective post-surgical aid. Given the recent advances in the development of PEMF devices, affordability and access will be much easier suited to the patient population, allowing for more readily available treatment options.

In this paper, a practical methodology of hand-manipulator motion coordination for indoor service robot is introduced. This paper describes the procedures of opening door performed by service robot as a noticeable example of motion coordination. This paper presents well-structured framework for hand-manipulator motion coordination, which includes intelligent sensor data interpretation, object shape estimation, optimal grasping, on-line motion planning and behavior-based task execution. This proposed approach is focused on how to integrate the respective functions in harmony and enable the robot to complete its operation under the limitation of usable resources. As a practical example of implementation, the successful experimental results in opening door whose geometric parameters are unknown beforehand are provided.

Gantry mechanisms have been widely used for precision manufacturing and material handling in electronics, nuclear, and automotive industries. Dual-drive servo mechanism is a way to increase control bandwidth, in which two primary axes aligned in parallel are synchronously driven by identical servo motors. With this mechanism, a flexible coupling (compliance mechanism) is often introduced in order to avoid the damage by the servo mismatch between the primary drives located at each side of gantry. This paper describes the design guidelines of the dual-drive servo mechanism with focus on its dynamic characteristics and control ramifications. That is, the effect on the system bandwidth which is critical on the system performance, the errors and torques exerted on guide ways in case of servo mismatch, the vibration characteristics concerned with dynamic error and settling time, and the driving force required at each axis for control are thoroughly investigated.

In this paper a passive compliant joint (PCJ) for human-friendly service robots is presented. The PCJ is composed of a magneto-rheological damper and a spring for elasticity. In the magneto-rheological damper, a braking force proportional to the electric current is generated. It works as a viscous damper by controlling the electric current according to the angular velocity of spring displacement. The compliance property and position control of the PCJ are verified through experiments and simulations to a single DOF simple arm with the PCJ.

This study is intended to evaluate and optimize the characteristics of smoke spreading and the appropriateness of evacuation time extended by operation of smoke control system during fire within the underground space of the building structured in compliance with the smoke control system performance criteria from the local fire safety standard, which has been currently applied to the buildings in Korea. Using the heat release per unit weight of the combustibles, a numerical analysis both in case of smoke control system in operation and the system not in operation was carried out at the several different shopping malls. From the viewpoint of securing the evacuation time, the results were compared in an attempt to assess the appropriateness of the fire safety criteria.
