Recently several hospitals have established a new nursing position so called, 'the nurse in charge of education (NCE).' The job description of NCE is to give a detail explanation on examination or test introduced to patients or a guide for those who are not familiar to hospital facilities at the out-patients level. The motivation of NCE position is the quality improvement in patient education on the sophisticated procedures or the follow up care for medical purposes to improve their compliances, as well in delivering services for outpatients or visitors in more informative and efficient way. The application of NCEA has been turned out positive and effective in patient satisfaction and unit management. However, special attention is brought to the scope and depth of the contents of education delivered by NCE which might overlap with the duty of physicians by the Medical Act. It is needed to clarify the role and job description of NCE in the context of Medical Act. The engagement of NCE to the Advanced Nursing Practitioner (ANP) is one of the possible solutions for a duty charge on patient education since ANP is a legislatively official position with higher license of RN at master level. Further discussion is needed to elaborate and arrange the details on the scope and content of patent education among health science professionals including RN, ANP and physicians.

The military respond well to external publics in the event of a crisis int that they are operated based on the trust of the people. Unlike other organizations, however, the Korean military has the distinctiveness that soldiers experience military life as internal publics for a certain period of time and after serving in the army, they become those who evaluate the military as external publics. Therefore, it is important to examine what would be effective crisis management strategies in terms of communicating with active-duty soldiers. Given that active-duty soldiers are accustomed to using SNS these days, this study investigated whether message forms (digital image vs. text) affect the perception of the military in crisis, acceptance of the given message, and attitude toward the military. Our empirical findings suggest that image-based messages are more likely to increase levels of message acceptance than text-based messages. Based on the results, we discussed practical implications on communication strategies for managing the military in crisis.

Improving fuel consumption, particularly that of commercial vehicles, has become a global concern. The reduction in logistics cost has been a key issue in efforts to improve fuel economy and efficiency of transportation equipment. Typical technologies for reducing reduce fuel usage include air resistance reduction technologies, tire rolling resistance technologies, and idle technologies among others. Air resistance technology is a highly effective method that can be easily applied in a short period. As with air resistance technology, several devices involving side skirt, boat tail and gap fairing have been developed based on an analytical 3-D modeling technique for reducing air resistance attributed to the vehicle configuration. The devices were on a 45 feet tractor-trailer and the emission test was done using PEMS equipment. Fuel economy was evaluated by introducing several devices to reduce outer air resistance. The test was conducted by changing the experimental method of SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure - Type II test. As a result, air resistance decreased by at least 15 % and fuel economy improved by at least 13 %. This study sought to reduce greenhouse gas and improve fuel economy by applying several devices to a test vehicle to lower air resistance.

Bodyguards always perform their duty with psychological burdens in their mind, not only because security situations are developed in various forms dependent on the surrounding environments or circumstances, but because bodyguards only take follow-up actions while the criminal decides time, place, and style of every attack. Thus, in the security situation, it is not uncommon for bodyguards to experience muscle rigidity, uncontrollable emotional elevation, difficulty in concentration, negative perception, frustration and enervation, which are caused by continuous physical/mental burdens, stimulations by various interpersonal behaviors or minute environmental stimulants. In conclusion, the result of performing security duties is related in the first place with the degree of the bodyguard's potential, in the second place with the degree of training and efficiency. And the result can also be changed by the way they control their negative psychological state of the moment when they carry out the skills they acquired. Maximizing the performance of the bodyguards by helping them overcome these psychological factors may be facilitated by detecting their psychological factors, understanding the causes, and training them in applying appropriate measures for overcoming these factors. When these measures are applied, the positive perception is indispensable that duties of protecting clients can be carried out successfully. No single measure can be declared to be more effective than the other because the effect of each measure is expressed differently by the individual characteristics of the bodyguards. However, it is important to select and apply the measures most appropriate to the bodyguard. Besides, they should devote themselves to the training with persistence because efficient implement of the measures for overcoming psychological factors takes a lot of time.

Purpose: Effective communication is an essential aspect of nursing care. This qualitative study was performed to analyze nurse-patient conversations about medication. Method: The nurse-patient dialogue was collected by video tape recording during the nurse's duty time in an internal medicine ward. One hundred seventy-eight episodes were extracted from the conversation. Using conversational analysis, the functional phases and patterns of dialogue sequence pertaining to medication were analyzed. Results: Conversations about medication were very brief dialogues, so 68.8% of the dialogue had a duration of less than 20 seconds. However, it was a systematic and comprehensive dialogue which had structures and sequential dialogue patterns. Four functional phases were explored. greeting, identifying the patient, medicating, finishing. The medicating phase was essential, in which the nurse gave the drug to the patient and provided information initiated by the nurse simultaneously. The patterns of the dialogue sequence represented were the nurse provided information first, and then, patients responded to the nurse as accepting, rejecting, raising an objection, or asking again later. Conclusion: As the results of this study show, a nurse's role is important as an educator. For effective conversation about medication, the development of an educational program should be considered, which includes knowledge about medication and communication skills.

An accumulator in hydraulic systems stores kinetic energy during braking action, and then that controls hasty surge pressure. An energy recovery system using accumulator seems to be advantageous for ERBS due to its high energy density. This study suggests a method to decide suitable accumulator volume for ERBS. The method is based upon energy conservation between kinetic energy of moving inertia and elastic energy of accumulator. The energy conversion was analyzed and a simple formula was derived. Also accumulator tests were conducted for different load mass and motor speed. A series of test work were carried out in the laboratory and the dynamic characteristics of the hydraulic motor system, such as the surge pressure and response time, were investigated in both brake action and acceleration action and these results show that the proposed design is effective for decision accumulator volume in ERBS.

This paper describes the testing and experimental characterization of a linear permanent magnet actuator, which is designed and developed for active vehicle suspension, under both static and dynamic conditions. Since the active suspension unit operates over a wide force-velocity range with varying duty ratios, it is essential to establish an effective thermal model which can be used for assessing temperature rise of the actuator under various operating conditions. The temperature rise of the actuator is measured and the results are compared with the prediction by the derived transient thermal model. It is shown that the measured actuator parameters and characteristics are closed to their predicted values. The linear actuator is controlled by a dSPACE system via a three phase inverter and its velocity tracking performance is presented.
