Purpose: This study was to explore gender differences on presenting patients with acute myocardial infarction in the emergency department. Methods: The survey was done with 143 emergency medical charts presented to the emergency department and diagnosed with acute myocardial infarction between January 2005 and December 2006. The collected data were analyzed with frequency, chi-square, and t-test. Results: Significant gender differences were apparent in age, route to the emergency department, elapsed time from onset of symptoms to arrival, and initial heart rate. Women were significantly more likely to report hypertension, diabetes, and congestive heart failure than men, but men were significantly more likely to report smoking. Chest pain was the most common initial symptom in both men and women. Women were significantly more likely to report dyspnea and nausea/vomiting than men. Conclusion: Although similarities exist in the associated symptoms of acute myocardial infarction, women might experience different symptoms, compared to men. These findings have implication that patients and health care providers should consider gender difference in presenting symptoms.

According to previously published paper the phase advance angle is adopted to the BLDC motor drive with high speed. The report proposed describes the optimum algorism that phase current is in phase with the initial flat region of back EMF. This report studies the need of more leading phase advance angle compared with in phase concept between phase current and back EMF. In case of high reactance this report proposes the more phase advance angle than in phase. The test results more rms value of phase current and output power due to more phase advance angle than in phase. It will be helped the high power operation of BLDC motor at high speed.

The computer-based simulation tools are currently used overwhelmingly to simulate the performance of automotive designs. Then, the search for an optimal solution that satisfies a number of performance requirements usually involves numerous iterations among several simulation tools. Therefore, meta-modeling techniques are becoming widely used to build approximations of computationally expensive computer analysis tools. The set-based approach proposed in the first report of a four-part paper has been a test bed for the innovation of vehicle structure design process in the Structural Design and Fabrication Committee of JSAE(Society of Automotive Engineers of Japan). In the second report, the proposed design approach is illustrated with a side-door impact beam design example using meta-modeling techniques.

Local anesthetics are an essential part of pain control during dental treatment. Despite its effectiveness and safety, patients should constantly be aware of potential adverse effects, including allergic reactions. Allergic reactions to amide-type local anesthetics (LAs), such as lidocaine and mepivacaine, are rare compared to those to ester-type LAs. Herein, we report the case of a patient with a history of allergy to lidocaine and mepivacaine, with symptoms of itching, diffuse erythema of the wrists and hands, dizziness, and pectoralgia. This case report emphasizes the importance of collecting medical and dental histories of patients is necessary, and how an allergy test in the allergy and clinical immunology department helps select safe LAs for patients.

Purpose : The act of reporting child abuse by people obliged to report child abuse is a way to detect long-term incidents of child abuse in early stages and to prevent a vicious cycle of social crimes. Thus, this study intends to enhance the reporting of child abuse through a study on the perception of people obliged to report child abuse through the public service announcement on child abuse. Methods : First, in order to identify the demographic characteristics of the subjects, the frequency and percentage were calculated. Second, in order to verify the reliability of the variables, Cronbach ${\alpha}$ was calculated. Third, in order to examine the perception of people obliged to report child abuse and the perception of reporting, a t-test (verification) and One-way ANOVA were conducted. Fourth, in order to identify the relationship between variables, a Correlation analysis was conducted. Result : The results show that people obliged to report child abuse did not perceive the public service announcement on child abuse positively and it varied depending on their jobs. The correlation between the public service announcement on child abuse and sub-factor of perceptions of reporting showed that a positive correlation was found in reliability, interest, understanding, perceiving the public service announcement on child abuse, perceiving severity and effectiveness, whereas a negative correlation was found in perceiving hazards. Conclusion : The education for preventing child abuse is required by the job type of people obliged to report. It is necessary to convey the message of effective public service announcement. The public service announcements on child abuse must be nationwide and long-term projects.

ATTOL is a software unit testing tool produced by the ATTOL Testware SA in France. It automates the entire software unit testing process: test plan template and test program generation, test program execution, test result analysis and test report generation. ATTOL is suited for the development of embedded software as it allows programmers to operate in native and cross development environments. Particularly, it is used for the development of the flight software which is embedded in the Communication Ocean Meteorological Satellite (COMS). As the flight software is mission-critical, it requires the strict software quality and high testing constraints. The flight software of COMS is verified by ATTOL in native and cross platforms. In 2002, ATTOL was taken over by the IDM Rational Software and has been supplied with the name of Test RealTime (TestRT). The test process of TestRT becomes different from that of ATTOL as TestRT provides the new functionalities that were absent from ATTOL. TestRT provides the new features in the test script language, as well. In this paper, we compare the test process of ATTOL to TestRT With an example of COMS and explain what has been changed in the test script language.

This report describes the procedure of detailed design and structural test for the composite flexure which is a part of the hingeless hub system. First, stacking sequence design for composite flexure was done, and structural analysis by using NASTRAN was made to verify structural stability and safety. Using FPS installed at KIMM, composite flexure was laid up and cured using a autoclave. Before rotor ground test, the basic structural tests such as a bench test, tensile strength test and shear strength test, for flexure, were accomplished. Through replacing existing metal hub part with new fabricated composite flexure, improvement of aeroelastic stability and weight reduction were achieved. This result will be applied to composite rotor system design fur helicopter.

This is a research report about the method of how to maintain qualification of certification flight test crews. KCA(Korea Certification Agency) have completed the KC-100 airplane certification flight tests which is the first time experienced flight tests operation. After the certification flight test, it has been found that annual flying time requirement of 100 hours to the certification flight test pilot is too strict, and other several requirements to maintain the qualification of the certification test crew such as aircraft certification introduction training, initial flight test pilot and flight test engineer certification training, crew resource management training, aviation physiology training, and survival training was difficult to implement in Korean civil aviation environments. In this study, it was suggested that 30 hours of flying time for maintaining certification flight test pilot qualification could be applied to contribute for safe operation of certification flight test and the other training requirements of the certification flight test crew could be fulfilled using self made training courses, existing FAA training courses and Korean Air Force training resources. Therefore, it is recommended that the regulation of maintaining the certification flight test crew qualification should be refined to implement the requirement practically.
