Twenty-first century coming of health care in our country is in a situation of much conflict because the relationship between nurses and doctors is seen in terms of a traditional and vertical structure. Accordingly. it is very difficult to find collaboration amongst individuals of these two professions. Now nursing is trying to find independence and autonomy by carrying out independent professional skills. This study on collaboration and the obstacles hindering its pursuit. The strategies of collaboration to give better health care quality are as follows; First, a program for professionals should be developed to enhance professional knowledge and technology and train nursing professionals so that nursing can be acknowledged as a profession with a power to carry out on independent job. Second, collaboration reduces expenses and results in satisfactory performances of duty, high productivity, low incidence of medical accident, and higher satisfaction of the patient. Therefore the leader in the higher position should take positive stance for collaboration and help create a cooperative situation through the development of practical orders for collaboration. opening cooperative wards, and meeting for collaboration. Third, a collaboration model should be introduced into the courses of the nursing and medical school curriculum, which would influence job atmosphere after graduation. Fourth, nurses should have pride in their jobs as professionals and have confidence in their professional skill, knowledge and ability. Nurses should make an effort to share responsibility and have independence and autonomy. Fifth, common people as well as doctors know little about professional practice and the role of nurses, so a publicity campaign is also required.

The current trend of the education market is the development of the fourth industrial revolution and the development of ICT, and various technologies are developing into edu-tech technology that is integrated into the education system. In particular, the market for edu-tech systems capable of lifelike immersive learning effects in virtual space is expanding. However, education in Korean medicine is not objective because of the absence of educational simulators and systems to train and evaluate acupuncture. In this paper, we propose an acupuncture controller and a human body model to increase the effectiveness of acupuncture point training as a follow-up study of "Design of Acupuncture Contents and Dummy for Acupuncture Point Training System". Through the proposed acupuncture controller and Dummy, the accuracy of acupuncture points for the acupuncture point data matching and content motion recognition rate is presented. In addition, the results of temperature and humidity and temperature change tests for evaluating the environmental reliability of the controller are presented.

This paper presents a methodology for identifying track irregularity using a wavelet transfer function. An equivalent wavelet SISO (single-input single-output) transfer function is defined by the measured track geometry and the acceleration data measured at a bogie of a train. All the measured data with various sampling frequencies were rearranged according to the constant 25cm reference recording distance of the track recording vehicle used in the field. Before applying the wavelet transform, measured data were regressed by eliminating those out of the range. The inverse wavelet transfer function is also formulated to estimate track geometry. The closeness of the estimated track geometry to the actual one is evaluated by the coherence function and also by FRF (frequency response function). A track irregularity index is defined by comparing the variance of the estimation error from the intact condition and that from the current condition. A simulation study has been carried out to examine the proposed algorithm.

This paper proposes a new wireless backhaul technology based on MHN(Mobile Hotspot Network) which uses a wide frequency band of millimeter wave to provide wideband Wi-Fi services for subway passengers. Performance analysis of MHN up and down links, based on data: up and down links structure analysis of physical layer and simulation study of the MHN wireless backhaul link model, show that the proposed MHN-based wireless backhaul network can transmit data at a 1.2Gbps data rate and provide Internet service 100 times faster than that of conventional WiBro-based wireless backhaul networks. These results indicate that the proposed MHN technology is appropriate for subway mobile networks.

Cultural Content Industry, a core industry based on knowledge, is becoming an economic model making new benefits by adding human creativity, imagination, sensitivity and style in to information technology. Cultural Contents Industry representing cultures of each countries is facing major changes towards a new competitive industry of each nation. Cultural content of a country is upbringing new contents power developing into a new industry by flattening the barriers within nations. But cooperations face difficulties in launching the industry because of limited information about the current market and lack of understanding in cultural differences. In order to solve this problem, this paper aims to create global network leading to increase of export and creation of new market with cultural contents and train local specialists. In order to search for the ways to maintain Korean contents in other nations and expand exportation. cooperations invite leading cultural contents groups to South Korea, let the groups experience Korea's contents. Cooperations initiated invite training, dispatch training by Korean companies and international students training. The purpose of this paper is to support education system, ETS-CS(Educational Training System for Contents Specialist) and analyse practices applied in the field to develop a better cultural contents industry.

This paper evaluated applicability of railroad reference points for determinating geoid heights. For this research, reference points on the Honam express raildroad which contain ellipsoid heights estimated by GPS/Leveling and orthometric heights by leveling were used. Geoid heights were calculated uisng orthometric and ellipsoid heights of 360 railroad reference points, and the RMSE's with respect to different intervals of reference points were analysed which were induced by interpolation methods. The results showed that no significant difference of RMSE's among interpolation. methods. RMSE's of 0-4km interval of reference points were determined within 2cm and 5-8km were within 3cm. Also, this research confirmed that GPS leveling with Geoid model is not auurate enough to be used for railroad surveying as yet.

Due to the rapid increase in demand for transportation of human and freight in modern railway systems, the CBTC system has been proposed, which is the solution for improvement of the line capacity that has been limited by the conventional track circuit based train control system. In the CBTC system, higher reliability of the communication system should be guaranteed for the safety of passengers and trains. However, due to the inherent characteristics of the wireless channel environment, performance degradations are inevitable. The diversity techniques can increase the reliability of data transmission using multiple antennas. In this paper, we investigate the performance of the STBC in the railway channel environment. Rician fading model is used for the viaduct scenarios which take important roles in the railway system. Also, considered is the Doppler effect which is an important factor in the mobile communication system. Simulations are performed to analyze the performance of the STBC in various channel environments. Results show that the performance degradation due to the phase error in viaduct scenarios is independent of the diversity order but is affected by the constellation of the modulation.

Since the vibration induced by a train is transferred directly to a station via a roadbed structure, the elevated station is particularly vulnerable to noise and vibration. To establish more appropriate measures to reduce vibration, the structural behavior and damping characteristics depending on the structural type and the composition of a elevated station should be identified, because the noise inside the station is mainly structure borne noise by the vibration of a station structure. In this paper, the vibration characteristic changes depending on mechanical connection types between an elevated station and a connected bridge are analyzed. The finite element model for Daecheon Station is constructed for the purpose of this study, and the analysis is performed using ABAQUS. The analyses are conducted for with and without bridge connections, and for the bridge connections, ramen and bearing types are considered in the analysis.
