Cross-Sectional Tests of Multifactor CCAPMs using Conditional Moments and Time-Series Restrictions
김진용 한국증권학회 2009 Asia-Pacific Journal of Financial Studies Vol.38 No.5
Two different methods are used to evaluate the performance of the consumption-based asset pricing models to explain the cross-section of expected stock returns in conditional moments: one is to scale the returns, and the other is to model time-varying factor loadings, using instrument variables. Max-imum correlation portfolios are constructed to directly impose restrictions on the time-series inter-cepts, especially in a model whose factors are not returns. The empirical results are as follow: the consumption-based models perform no better than the standard CAPM; adding the return on human capital as an additional risk factor does not help explain the cross-section; and the Fama-French three-factor model shows the best ability to lower the pricing error.

In traffic accidents, wearing a seatbelt can cause abdominal aortic injury due to an abrupt deceleration. We report a case of abdominal aorta dissection caused by a seat belt in a frontal motor vehicle collision. The initial symptoms and signs were vague or uncertain. However, he complained severe abdominal pain with seat belt sign below the umbilicus. Abdominal computed tomography scans showed an initial flap of the abdominal aorta with hematoma and hazy stranding of the mesentery.
메티실린 내성 황색포도알균 주사부위 감염 후 발생한 척추추간판염 1예

Infections of the intervertebral disc and adjacent vertebrae may present with spondylitis, discitis and spondylodiscitis and are hematogenous origin in most cases. Potential sources of hematogenous infection are skin and soft tissue infection, genitourinary tract infection, infective endocarditis, intravenous drug abuse, respiratory tract infection and infected intravenous injection site. We have experienced a case of pyogenic spondylitis caused by methicillin-resistant Staphylococcus aureus (MRSA) bacteremia with peripheral injection site infection. He was successfully treated with surgical debridement and antibiotics. 본 증례는 약물남용자가 아닌 환자에서 MRSA에 의한 말초주사부위 감염 후 발생한 화농성 척추추간판염의 첫 보고이다. 최근 MRSA에 의한 원내감염이 증가하고 있는 현실에 비추어 볼 때 말초주사부위 감염 후 MRSA에 의한 화농성 척추추간판염의 발생을 고려하여야 한다.
A Simple Dual-Antenna Diversity Gain Measurement System at 2.4GHz
김진용,정경호,김문일,호요철 한국전기전자학회 2009 전기전자학회논문지 Vol.13 No.2
A simple measurement system is built to estimate the dual-antenna diversity gain at 2.4GHz easily in open lab environment. To obtain multipath fading propagation channel, the system consists of two transmission horn that placed on opposite direction and a rotating stage mechanically changing the position of test dual-antenna with time over distance greater than one wavelength. Estimated diversity is nearly same as theoretical value such that measured diversity gain of 30mm separated is about 6dB similar to theoretical value of 5.7dB and increases monotonically with the increasing separation distance as predicted by the theory. Proposed measurement system that is simple enough to fit in a small space can evaluate the performance of various dual-antennas with a reasonable accuracy with lower 5% difference between the ten sets of measured waveform distribution and theoretical Rayleigh cumulative distribution.

Purpose: Packing the nose is a common procedure after the closed reduction of a nasal bone fracture to prevent postoperative complications, such as bleeding and adhesion formation as well as to stabilize the framework of the nasal bone. On the other hand, it is difficult for a patient to endure nasal packing because of breathing difficulties, headaches, chest discomfort, insomnia, general weakness and hypoxia. This study examined the availability of a bronchodilator to improve the decreased oxygen saturation and postoperative symptoms on nasal packing. Methods: From February, 2010 to July, 2010, a prospective randomized comparison of the incidence of a range of postoperative signs and symptoms was conducted on 60 patients, who did (n=30) and did not (n=30) undergo bronchodilator infusion (aminophylline 250 mg/10 mL + normal saline 100 mL IV qd) following nasal packing. The postoperative symptoms and oxygen saturation in the two groups were compared. Results: Patients who had infused the bronchodilator showed improved oxygen saturation. Nevertheless,there were no significant differences in the postoperative uncomfortable symptoms (dyspnea, headache,chest discomfort, insomnia, general weakness) between the two groups. Conclusion: A bronchodilator after nasal packing improves oxygen saturation by dilating the airway tract but it cannot reduce the uncomfortable symptoms caused by nasal obstruction. Overall, the bronchodilator is a useful medication for improving the level of oxygen saturation. (J Korean Cleft Palate Craniofac Assoc 12: 22, 2011)
