Background: To implement medication management service in Korean nursing home (NH), medication review tool for residents in Korean long-term care facilities was developed. This prospective pilot study aimed to verify the applicability of this newly developed tool and to evaluate the drug related problems (DRPs) identified by pharmacists' medication review in NH setting. Methods: This study was carried out in two NHs in Korea. The elderly residents (65 or older) using 5 or more medications were eligible. Pharmacists conducted medication review and identified the DRPs and potentially inappropriate medications (PIMs) based on the newly developed tool. Results: Among 43 NH residents, 27 residents agreed to participate. The median age was 87 and about 55.6% of them were taking 10 or more medications. Pharmacists identified a total of 37 PIMs in 18 NH residents (66.7%) and 54 DRPs in 22 residents (81.5%). The most frequent PIM was general-PIM (26 cases) followed by PIM under specific diseases or conditions (7 cases). Out of 77 items contained in the tool, 15 items were detected in study participants. 'Continued use or regular daily use of hypnotics' was the most highly detected item (9 cases) followed by 'multiple prescriptions within each class of hypnotics/sedatives' (5 cases). Among 54 DRPs identified, pharmacist intervened 39 cases (72.2%) and interventions were accepted in 18 cases (46.1%). Conclusion: This pilot study demonstrated that newly developed tool is feasible for the nursing home residents. However, further studies with larger population are warranted.

As one of recent issues in the information and communication industry, internet of things has attracted attention to provide intelligent infrastructure services which connect and share data and information between real and virtual world. According to the development of these internet of things technologies, types of machines, telecommunication devices, and terminals are increasing tremendously. In this situation, connectivity and interoperability between internet of things components are important issues to build a hyper connected society. To visualize this society, it is important to set up and develop information and communication technology (ICT) standards among stakeholders. However, under limited budget and human resources, it is essential to rank standardization work items for setting standards with respect to efficiency. The purpose of this study is to provide a method for setting standardization strategies within group decision making. As a multi-criteria group decision making tool, analytic hierarchy process (AHP) is adopted and applied to determine the priorities of setting work items. The proposed method first defines decision making problem with objective, criteria, and alternatives which produces a hierarchy consisting of upper and lower criteria. Then, pairwise comparisons of academy and public sector experts are performed with respect to their relative meaning and importance. Individual surveys of expert groups are collected and summarized to determine relative criteria importance measures. Furthermore, to deliver reliable importance criteria measures, differences between academy and public sector expert groups are compared and tested using Mann-Whitney non-parametric test. The results are illustrated for useful guidelines to practical group decision making in standardization strategy establishments.

The purpose of this study was to determine the effects of various cutting conditions on the cutting resistance and surface roughness of material in turning operation using a carbide tool. The workpiece materials were the carbon steel SM20C and SM45C. The results of this study are summarized as follows: The cutting force decreases as the feeding amount and cutting depth decrease and the cutting speed increases. In order to obtain a proper surface roughness to each material, it is desirable to set the feeding amount as 0.059mm/rev, the cutting depth as 0.4mm and the cutting speed as 270m/min for SM20C, while setting the feeding as 0.059mm/rev, the cutting depth as 0.6mm and the cutting speed as 270m/min for SM45C.

This paper describes a design scheme of a system that tests or polls from the students at online class. By online test, the teacher can test the pre-knowledge level of the students and know how much students understand the lecture of the class. As the number of test increases, the burden of the preparation of setting question, evaluation of the test, and management of the test results is increased. In this environments, an online test management system make it easy to test and evaluate, and thus it would be a good tool for maintaining and managing the total procedure of the test or poll of the students. For evaluating the design of the system, we made a test system prototype and performed evaluations of the online test system. The online test and evaluation system provides a good tool for testing and evaluation of student's knowledge at the class with easy and fast way.

To improve the accuracy of products and improve the product quality, we need to enhance the machining accuracy of the machine tools. To this point of view, measurement and inspection of finished part as well as error analysis of machine tools has been studied for last several decades. OMM(On the Machine Measurement) has been issued to alternate with CMM, pointing out disadvantages of high expenses and lots of setting time in CMM. In this paper, we study 1) the spherical surface manufacturing by volumetric error compensation of machine tool, 2) the system development of OMM without detaching work piece from a bed of machine tool after working. 3) the generation of the finished part profile by On the machine measurement. Furthermore, the output of OMM is compared with that of CMM, and verified the feasibility of the measurement system.

A polishing machine adopting a new unique structural mechanism has been developed, named as a swing-arm type polishing machine. The mechanism is such that the tool path tracks on a spherical surface, of which the diameter is adjusted by setting up the machine mechanism properly. It has a strong benefit especially for polishing axis-symmetric concave mirror surfaces. The swing-arm type polishing machine with 5-axes has been designed in order to polish a concave mirror surface lip to diameter of 2 meters. The drawings are made using 3D CAD and strain-stress analysis has been done by finite element method. AC servo-motor has been used to move the swing arm and a operating software has been developed using a LapVIEW tool. Result of the test run was satisfactory which convinces the usefulness of the swing-arm type polishing machine.

High-accuracy micropatterns such as V-shaped microgrooves are increasingly in demand for various engineering areas. And the technical trend goes for large surface areas in precision machining technology. So micropatterns with large surface areas are expected to play an increasingly important role in today's manufacturing technology In this study, we focused on developing machining technologies. First, a machine vision system for precise tool setting is developed. Second, an on-machine measurement (OMM) system for large-area measurement is implemented. And also software for tool path generation and simulation is developed. With these technologies we fabricated large-surface micropatterns in an electroless nickel-plated workpiece with single-crystal diamond tools and a 32-in, $675mm{\times}450mm$ mold with tens of V-and pyramid-shaped micropatterns.
