Purpose: This study was conducted to examine and compare clinical manifestations and predicting factors for treatment-seeking delay among patients <65 and ${\geq}65\;yr$ with first-time acute coronary syndrome (ACS). Methods: A total of 288 patients who were diagnosed with ACS were individually interviewed at C university hospital in G-city from November 2007 to December 2008. Results: Median pre-hospital delays for younger and older patients were 5 and 12 hr, respectively. Younger patients were more likely to be current smokers, heavy drinkers, obese, stressed, and have an unhealthy diet and family history, and to complain of chest pain, left shoulder and arm pain, perspiration, and nausea. Older patients were more likely to have hypertension and diabetes, and to complain syncope and dyspnea. Logistic regression analyses showed that after adjustment for age, gender and education, progressive onset of symptom and no attribution to cardiac problem significantly predicted pre-hospital delay >3 hr in both younger and older patients. Low perceived health status was a significant independent predictor in older patients only. Conclusion: Health care providers should be concerned with different manifestations between younger and older adults, and educate people at risk for heart attack about symptoms and actions to get immediate help.

This is a report of three cases of successful embolectomy in peripheral arteries. First case was the patient who received a mitral commissurotomy 8 months ago. In that time, there was no evidence of left atrial thrombosis. He showed an embolism in the middle portion of left brachial artery without complaining of any ischemic pain. Embolectomy was performed 15 days after disappearance of radial pulse and resulted in no return of radial pulse postoperatively. Second case was a case of an embolism in lower portion of right brachial artery. She complained severe ischemic pain and cyanosis in the right forearm and fingers. She was also in the beginning state of cardiac failure, which was suspected from her hypertension associated with cardiomegaly and arrythmia Embolectomy was performed 17 hours after onset of acute pain. Immediate full pulsation of radial artery was obtained after embolectomy and the acute ischemic symptoms subsided gradually. Third case was an embolism in superior mesenteric artery which occured 24 hours after pneumonectomy for right bronchogenic carcinoma and the patient suddenly complained diffuse abdominal colicky pain. 7 hours after attack of abdominal pain. embolectomy with extensive reset ion of the small intestine was performed with uneventful recovery and without complication, such as short bowel syndrome, postoperatively. Histopathologically, the embolus was consisted of a tissue of anaplastic cell carcinoma, which was identical to the tumor of the resected right lung. Histological findings of other emboli of first and second case were old thrombus.

Background: Idiopathic facial nerve palsy, or Bell's palsy (BP), is a common and important disease. Recurrent Bell's palsy has been known as a rare entity with only a few cases in the literature. Methods: A total of 111 consecutive patients with acute BP patients were enrolled at Daegu Catholic University Hospital from July 2005 to March 2007. We classified the patients into two groups - single BP and recurrent BP - and compared them by demographic data, clinical features, MRI findings and prognosis. The degree of BP was graded according to the House and Brackmann facial nerve grading system. Results: Recurrent BP was observed in 10 (9%) patients. The number of recurrence was varied from 2 to 5. The mean age of first attack in recurrent BP was $35.70{\pm}23.65$ years old and was earlier than that of the single BP ($50.94{\pm}16.21$ year). The larger proportion of the single BP had an abnormal enhancement of affected facial nerve (91.3%) than the recurrent BP (50%). The recurrent BP showed worse prognosis than the single BP. The associated conditions, etiology, and clinical features were similar between two groups. Conclusions: In comparison with single BP, recurrent BP showed earlier onset of first BP attack, less frequent abnormal enhancement of facial nerve on MRI, and worse prognosis.

This study was carrid out to examine a part of the mechanism for the etiology of diabetic complications. Thirty normal and forty streptozotocin(STZ)-induced diabetic rats were used as the animal models. Animals were sacrificed at the time points of 3 days, 1, 2, 4 and 6 weeks after STZ-injection and time course in body weight and organ weight, the levels of blood glucose, plasma lipid patterns, and atherogenic index were measured during 6 weeks. The STZ-diabetic animals showed 63% survival rate and fsting blood glucose levels of the diabetic animals measured in the range of 230-410mg/dL during the experimental period. The body weigh of diabetic animals decreased significantly throughout the experimental period and the relative weights of organs to body weight were significantly higher than the normal control ones. The enlargement of the kidney in the diabetic animals was especially remarkable. Plasma triglyceride concentration in diabetic rats substancially increased from the first week of onset of diabetes mellitus and maintained higher levels than the control ones throughout the whole experimental period. The plasma total cholesterol level and atherogenic index in the diabetic rats were significantly higher than the normal ones from the third day after STZ injection and showed a gradual increase with the duration of the disease. Throughout the experiment, the diabetic rats consistently showed a slightly lower HDL-cholesterol level compared to the normal animals. From the results of this study, it appears that the significant changes in blood lipid pattern in STZ-diabetic animals start from the first week after STZ injection.

Background: Atrial fibrillation (AF) is one of the most common complications after cardiac surgery. Several therapeutic and preventive strategies have been introduced for postoperative AF, but the treatment and prophylaxis of AF remain controversial. We aimed to compare the efficacy of intravenous amiodarone and oral propafenone in the treatment of AF after coronary artery bypass grafting (CABG). Methods: This was a randomized controlled trial performed in two hospitals in Shiraz, Iran from 2009 to 2012. We included all patients who underwent elective CABG and developed AF postoperatively. The patients were randomly assigned to receive propafenone or amiodarone. The duration of AF, the success rate of the treatment, the need for cardioversion, the frequency of repeated AF, and the need for repeating the treatment were compared. Results: The duration of the first (p=0.361), second (p=0.832), and third (p=0.298) episodes of AF, the need for cardioversion (p=0.998), and the need to repeat the first and second doses of drugs (p=0.557, 0.699) were comparable between the study groups. Repeated AF was observed in 17 patients (30.9%) in the propafenone group and 23 patients (34.3%) in the amiodarone group (p=0.704). Conclusion: Oral propafenone and intravenous amiodarone are equally effective in the treatment and conversion of recent-onset AF after CABG.

Brief history of home economics education after modern period (GAEWHA-KI) (1900~1945). Education of home economics in our country is known to have been developed mainly through school education by need of women education. The first period is construed "from 1890's until before the conclusion of ULSABOHO treaty, which can be referred to as an inception of the education for home economics by including subjects of sewing and manual arts in the curriculum of EWHA-hakang. The second period is "from the conclusion of ULSABOHO treaty in 1905 until the act of higher education for women was decreed, transition of the education for home economics and major curriculum thereof and the text books of home economics are handled. The third period is "from the promulgation of CHOSUN education act in 1911 until the fall of Japan education of home economics in this period is described in terms of national education under the Japanese colonial rule. The education was first renewed by women missionaries with the onset of "blooming period (GAEWHA-KI)" and school education of home economics far educating women was initiated at EWHA-hakdang in 1896, in 1908, with the pronulgation of the act of higher education for women, major curriculum and subjects were set up and text books of home economics were also compiled. In accordance with CHOSUN education act in 1911, housekeeping and sewing subjects at secondary school were taught 10 hours a week with the emphasis on general education and practical subject oriented training. Home economics under the Japanese rule was so educated as to imbue, students with the sense of nationality by teaching Korean custom and family habits.

In this paper, we introduce the 3D modeling of the coronal magnetic field in the solar active region by extrapolating from the 2D observational data numerically. First, we introduce a nonlinear force-free field (NLFFF) extrapolation code based on the MHD-like relaxation method implementing the cleaning a numerical error for Div B proposed by Dedner et al. 2002 and the multi-grid method. We are able to reconstruct the ideal force-free field, which was introduced by Low & Lou (1990), in high accuracy and achieve the faster speed in the high-resolution calculation (512^3 grids). Next we applied our NLFFF extrapolation to the solar active region NOAA 10930. First of all, we compare the 3D NLFFF with the flare ribbons of Ca II images observed by the Solar Optical Telescope (SOT) aboard on the Hinode. As a result, it was found that the location of the two foot-points of the magnetic field lines well correspond to the flare ribbon. The result indicates that the NLFFF well capture the 3D structure of magnetic field in the flaring region. We further report the stability of the magnetic field by estimating the twist value of the field line and finally suggest the flare onset mechanism.

To evaluate remodeling of infarcted myocardium with contrast-enhanced MRI (co-MRI) at true end-diastole (ED) MRI was performed with a Gyroscan Intera (1.5 Tesla, Philips, Netherlands) in 13 patients with acute subendocardial myocardial infarction. The First exam was done 0-15 days (mean 5.2days) after symptom onset and the second exam 28-88days (mean 49 days) after the first exam. Ce-MRI encompassing the entire left ventricle was performed with a multi-shot, turbo-field-echo, breath-hold sequence and a non-selective, inversion prepulse 10 minutes after the intravenous injection of Gd-DTPA at a dose of 0.2 mmol/kg body weight. To allow the long TD, ECG synchronization should use two RR-intervals for one acquisition of a segment of k-space by setting the heart rate to half that of the true heart rate. Trigger delay time (TD) was adjusted to the RR-interval for true end-diastolic imaging. The other typical parameters were TR=5.4ms, TE=1.6ms, voxel size=1.37${\times}$1.37${\times}$10mm, k-space data segmented into 8 segments with 32 lines of segment per two cycles over 16 cardiac circles. The thickness of hyperenhanced myocardium and epicardially nonenhanced myocardium were followed.

Argininosuccinic aciduria (ASAuria) is a rare autosomal recessive urea cycle disorder. Neonatal presentation of ASAuria is the most common form. It is characterized by lethargy, feeding intolerance, decreased consciousness, and coma after 24 to 72 hours of birth. We describe a rare case of ASAuria in a female neonate who presented with severe hyperammonemia, a typical characteristic of urea cycle disorders. This patient's diagnosis was confirmed by biochemical analyses, and we found that the patient had a point mutation of the argininosuccinate lyase gene, which was homozygous for a novel 556C>T substitution. We have never seen the neonatal form of ASAuria in Korea. Therefore, this is the first report of neonatal onset ASAuria in Korea.
