This study represents the current situation on the Korean Government's investigation into the imports with the infraction of the country of origin indication law, showing how much those imports affect the purchasers as well as the domestic competitors in Korea. According to the HS 4 unit, the range of imports with the country of origin indication should be 55.2% of all imports, but it turned out there were actually 87.6% of them, according to the number of the import declarations in the first half year of 2010. The government's investigation on the infraction of the country of origin indication is conducted in the stages of customs and distribution into market. As a result of recent 4 years government's investigation into the imports with the infraction of the country of origin indication, the rate of inspection was averagely 3.6% of the reported number of imports in the stage of customs, the rate of the infraction of the country of origin indication cases was 0.14% of the total reported number, and 3.85% of the total actually inspected number. The investigation in the stage of distribution was below 20% level of the stage of customs inspection, on the number of caught cases basis. A survey of 4 categorized imports such as Watches, Tools, Glasses frames, and Clothes, which are assumed to happened frequently with the infraction cases, shows that the decreased sales rate of the domestic competitors was averagely 18.8% and the extent of the damage on consumers was 34.7% of the purchased prices, with both rates resulted from the investigation in the stage of distribution into market.

Background : The purpose of this study is to investigate the influencing factors on the length of emergency department stay of patients with acute myocardial infraction. Methods : we reviewed medical records of all patients who were Hospitalized with acute myocardial infraction from March 1, 2002 to February 28, 2003. Results : The average length of stay in the emergency room of the subjects was 182.74 minutes. After the emergency room treatment, 48.1% of the subjects were transferred to intensive care unit. The hospitalization through emergency room mostly took place in the office hours. There were more patients on Monday. The influencing factors on the length of stay in the emergency room of patients with acute myocardial infraction were emergency room arrival time which was classified in seasons, treatment hours of specialized doctors, medical care insurance and required time of radiologic examination. Conclusion : In order to reduce the length of emergency room stay, it might be an available solution secure enough spaces, facility, and staff of the radiologic test only for the patients of the emergency room. And the effective use of emergency facility and space, establishment of standardized treatment guideline, and provision of emergency treatment support system are also needed.

Background: The therapeutic potential of Bee Venom Pharmacopuncture (BVP) on acute ischemic cerebral infraction was determined in mice in vivo and in vitro. Methods: Analysis of acute ischemic cerebral infraction was performed using 7 week old male ICR mice (n = 20) and microglial BV-2 cells. Bee venom ($5{\mu}g/kg$) was injected into the caudal vein of middle cerebral artery occlusion (MCAo) mice (1 hour after reperfusion, 3 hours after MCAo probe insertion), and also used to treat LPS-stimulated microglial BV-2 cells (1, 2, $5{\mu}g/mL$). Markers of inflammation were monitored. Results: NO declined statistically significantly in BVP treated MCAo mice compared to the untreated MCAo group (p < 0.05). Compared to the MCAo group, the BVP-treated MCAo group showed a decreased production volume of malondialdehyde, but an increased glutathione/oxidized glutathione ratio. Compared to the untreated MCAo group, the BVP treated MCAo group showed a statistically significant decline in TNF and $IL-1{\beta}$ levels (p < 0.05). BVP inhibited the levels of p65, p50, $p-I{\kappa}B-{\alpha}$, and levels of p-ERK1/2, p-JNK2, p-P38 declined. Conclusion: BVP is effective at dampening the inflammatory response in vivo and in vitro and may supplement rt-PA treatment.

Purpose: We compared the results of three surgical procedures of the old neglected Freiberg's disease that was managed with metatarsal head reshaping, metatarsal head resection, and dorsal closing wedge osteotomy. Materials and Methods: From march 1996 to July 2002, five cases in six patients whose metatarsal head collapse already progressed underwent operative treatment. We compared the operative results in the view point of the radiographic follow-up and lesser toe metatrasophalangeal joint scale of AOFAS. Results: There were no further joint destruction and loose body formation. Also, lesser toe metatrasophalangeal joint scale of AOFAS improved from average score, 38.5 (range $22{\sim}49$) of preoperative one to average score, 86.6 (range, $72{\sim}100$). Especially, the 2 cases that underwent dorsal closing wedge osteotomy showed most favorable result and the 2 cases with metatarsal resection showed next favorable result. The 2 cases with intra-articular loose body removal and metatarsal reshaping showed the least effective result among three operative methods. Conclusion: Our Operative experiences of old neglected Freiberg's disease were all satisfactory irrespective of operative options and dorsal closing wedge osteotomy was thought to be most effective method.

Myocardial infarction is a disease caused by stenosis of the coronary arteries. The high risk of sudden cardiac death due to myocardial infarction has triggered related researches that have been actively studied so far. However, these studies focused on the clinical results, which are mainly based on observations of symptoms due to infarction through electrocardiograms. Therefore, in this study, we tried to analyze the behavior of heart according to the position and volume of infarction lesion through the computer simulation study using three dimensional ventricular models. In order to implement infarction, commercial software was used to simulate cell necrosis due to blockage of a specific coronary. In addition, the conduction block due to infarction was mimicked by reducing the electrical conduction in the infarcted area, which was 100 times less than the electrical conduction of the whole ventricular lattice implemented by the finite element analysis method. Thus, this study classified the infarcted cases into the upper, middle, lower, and apex according to lattice data of eight different infraction areas. In other words, we assumed that myocardial infarction would have inherent electro-dynamic characteristics depending on the location and extent, and analyzed the ventricular electromechanical responses for infarction lesions using a three dimensional cardiac physiome model. The results showed that the volume of infarction did not directly affect the cardiac responses, but the location of the infarction lesions could influence the ventricular pumping efficiency. These suggest that the occlusion of specific coronary arteries may have a fatal effect on the decline in ventricular performance. In conclusion, although location of myocardial infarction lesions is considered to be an important variable to be considered clinically rather than lesion size, quantitative predictions should be made more in the future considering physiological factors such as lesion location and direction of myocardial fiber at that location.

Objective : Hyperhomocysteinemia has been proven to be an independent risk factor for stroke. The genetic mutation of methylenetetrahydrofolate reductase(MTHFR) elevates serum homocysteine level, but it still remains controversial whether the MTHFR gene mutation could be a predictor of ischemic stroke. Therefore, we studied if this genetic defect could cause ischemic stroke independently. Methods : We gathered ischemic stroke subjects and age, sex-matched controls. Age, gender, past medical history, smoking habit, serum homocysteine level, and the MTHFR genotype were recorded. General characteristics of ischemic stroke subjects were compared to the controls. We classified the stroke according to the related vessels(small and large artery infarction) and single lesion and multiple infraction. Relevant risk of the MTHFR genotype was evaluated in each stroke subtype with multiple logistic regression analysis. Results : When the controls were compared to the whole ischemic stroke, there was no specific difference except some medical histories. However, further analysis based on stroke subtypes showed important results. The small artery infarction group, multiple infraction group had significant odds ratio of the MTHFR TT genotype adjusted for age, gender, medical history and smoking habit. Conclusions : The MTHFR TT genotype is an independent risk factor for certain types of ischemic stroke, small artery infarction and multiple infarction.
