Objectives : The purpose of this study is to suggest how to interpret the 'practice of Korean Medicine', differentiating it from 'medical practice'. Methods : I analyze the legislations and precedents regarding the practice of Korean Medicine. Results : The Korean Medicine and Pharmaceutics Promotion Act defines 'practice of Korean Medicine' and it clearly differentiates it from the definition of 'medical practice'. However, the scope of this definition is somewhat restricting and it can violate doctors of Korean Medicine's right to equality and their academic freedom. Thus, the application of this definition of the 'practice of Korean Medicine' should be limited to the field of research and development. Meanwhile, criteria of distinguishing 'practice of Korean Medicine' from 'medical practice', which used to make a sharp distinction between Medicine and Korean Medicine by rigorously applying their academic standards, are now focusing more on protecting and improving health of the people. Discussions & Conclusions : I suppose that the distinction between the 'practice of Korean Medicine' and 'medical practice' will be more focused on public health rather than the academic stance of those two medical fields. Meanwhile, in accordance with dualistic medical system, the mutual usage of medical equipment in the area of 'treatment' should be limited while it should be allowed in the area of 'diagnosis' if it satisfies requirements suggested by the Constitutional Court.

Being able to quickly locate valuable medical equipment is critical inside hospitals. In order to utilize limited budget and resources efficiently, accurate locating or tracking is required in many fields. In this research, we focus on how to find the location of missing assets by using RFID in real time indoors to track equipment. When equipment needs to be searched, the purpose of a RFID device is to minimize the time, investment cost and effort spent searching for the equipment. Thus, this research presents a mathematical model of using RFID (both handheld reader and stationary reader) for efficient asset location. We derive the expected time of locating RFID-tagged objects in a multi-area environment where hand-held RF readers are used. We then discuss where to deploy stationary RF readers in order to maximize the efficiency of the search process.

The extensive use of polymeric matrix composites in the athletic sector may be attributed to its high strength-to-weight ratio, production economy, and a longer lifespan than conventional materials. This study explored the impact of carbon nanotubes on the properties of different composite field sports equipment components. The test specimens were fabricated using the compression molding technique. The insertion of carbon nanotubes increases mechanical properties related to the process parameters to account for an improvement in the stick sections' overall performance. The dynamic response of functionally graded reinforced nanocomposite wire structure is examined in this paper on the bases of high-order hyperbolic beam theory lined to the size-dependent nonclassical nonlocal theory under the external mechanical load due to the physical activities. Finally, the impact of different parameters on the stability of nanocomposite structures is discussed in detail.
