Differentiated On Off line channel strategies are getting more attention due to conflicts between Off line channel and active E commerce. Choosing an appropriate channel strategy can prevent apparel products from clashing in market and manage each channel more efficiently. In fashion industry, product prices are flexible because of the short product life cycle and different distribution channels. It is essential to understand consumers’ apparel price cue perception when purchasing apparel in both On line and Off line. The objectives of this study was to examine the effects of apparel price cues on perceived savings and purchase intention in On line versus Off line retail channel. 303 quetionnaires from internet experienced women were used for the data analysis. Statistical analyses employed in this study were descriptive statistics, reliabilities conjoint analysis and regression. Overall, the perceived importance of apparel price cues were different between On line and Off line channels and each apparel price cue affected perceived savings and purchase intention differently according to distribution channels. Therefore, by considering characteristics of apparel price cue in On line versus Off line channels, differentiated channel strategies should be imposed to implement more effective marketing strategies.

도플러검사법을 이용한 새로운 심기능평가법 : 급성 심근경색증에 의한 심기능장애의 선별진단법으로서 심기능지표의 유용성 The Utility of Cardiac Performance Index in the Screening Test of Cardiac Dysfunction due to Acute Myocardial Infarction

Background : Because systolic and diastolic dysfunction frequently coexist in acute myocardial infarction (AMI), we hypothesize that a combined measure of ventricular performance using Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic chest pain. Method and Results : Seventy-one patients with AMI (47 male, 59±11 years) and 45 patients with normal coronary artery (29 male, 52±11 years) were included in the study for measurement of cardiac performance index and established parameters of ventricular function using conventional echo-Doppler methods. a new derived index of cardiac performance: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The mean value of the index was significantly different between normal and AMI(p<0.01). The degree of inter-group overlap was smaller for the index compared to other parameters. within functional groups, the value of the index did not appear to be related to heart rate, mean arterial pressure and the degree of mitral regurgitation. Conclusion : cardiac performance index is a conceptually new, simple and reproducible Doppler index of combined systolic and diastolic myocardial performance, and it is useful as screening test for patients with cardiac dysfunction due to AMI

Thymus is a lymphoid organ forming T-cells from hematogenous stem cells. Apoptosis of thymocytes in the cortex of thymus is so rapid that cannot find easily with routine histological techniques. In this experiment, Comet assay and SDS-PAGE were used to detect apoptotic changes and protein changes after 5-fluorouracil(5-FU) treatment in the thymus of the rat. The results were as follows. 1. The number of thymocytes in the cortex was markedly decreased, and many apoptotic cells with various size and shapes were found on DAT 5 in 5-FU treated group. 2. On DAT 5, new nodules with germinal centers began to appear in the peripheral cortex, and in the germinal center, there was many apoptotic bodies of various size and shapes. 3. In SDS-PAGE, a protein with molecular weight of 123kDa was increased on DAT 5 which was considered as integrins subfamily.

This study was carried out in order to investigate the possibility of frozen rice batter for the manufacturing of Jeung-pyun. Despite of its unique taste and texture, Jeung-pyun is not consumed much because it needs long time to make. The physicochemical, sensory, rheological and surface characteristics of Jeung-pyun were analyzed to develop the easy manufacture method. The storage condition of rice batter was used at -20℃ up to 4 weeks. Statistical data analysis was completed using a SAS program. The results are summarized as follow: The pH, brix% and sugar content of all samples which added low-temperature tolerance raw yeast or regular raw yeast decreased during the fermentation. Kind of yeast did not influence on the moisture content of the Jeung-pyun batter. Specific volume and carbon dioxide evolution of Jeung-pyun batter were highest when the rice batter was frozen for 1 week regardless of the kind of yeast. Overall quality of frozen batter of Jeung-pyun at -20℃ for 4 weeks had the highest score among different samples. As the test results of mechanical characteristics, cohesiveness, gumminess, brittleness, hardness and springiness did not show any significant differences statistically. The result clearly suggests that freezing the rice batter is a possibile way to manufacture Jeung-pyun.

Transcatheter arterial chemoembolization (TACE) has become an effective alternative treatment strategy for patients with inoperable hepatocellular carcinoma (HCC). Although TACE is relatively safe, acute respiratory distress syndrome associated with pulmonary lipiodol embolism is a rare and potentially fatal complication. We report a rare case of acute respiratory distress syndrome after TACE for inoperable HCC. A 75-year-old man, with huge HCC in right lobe, was treated by TACE for the first time. Seven hours after uneventful TACE procedure, he felt dyspneic and his oxygen saturation recorded by pulse oximetry (SpO2) fell to 80% despite of applying non-rebreathing mask. He underwent mechanical ventilation with a protective ventilatory strategy. We experienced a case of acute respiratory distress syndrome after TACE for HCC.

Actinomycosis is a chronic suppurative infection, whitch infiltrates mucosa-associated tissues. Thoracic, pelvic and cervicofacial infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. We report a case of a 29 year old man who presented with a recurrent pneumonia and chronic cough. Fiberoptic bronchoscopy revealed occlusion of the right. lower medio-basal segment bronchus with exophytic endobronchial mass. The diagnosis was confirmed histologically by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of amoxacillin and clindamycin followed by oral amoxacillin and clindamycin therapy resulted in complete recovery.

The expression frequency of BrdU-induced fragile sites was examined in stomach cancer patients to determine whether this parameter could be used as a marker of genetic susceptibility in at-risk individuals. G banding performed to detect fragile sites. No difference was found in expression frequency between the stomach cancer patients and a group of normal individuals(p=0.7). This indicates that the expression frequency of BrdU-induced fragile sites is not a suitable marker for assessing genetic susceptibility in stomach cancer patient.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

Although cadmium is a well known heavy metal which attacks testis and results male infertility, the mechanism of action in the testis is'nt still fully known. In the previous experiment, authors observed morphological changes in the testis, and found cadmium-induced death of all the spermatogenic cells and hemorrhagic necrosis within the seminiferous tubules, and apoptosis and death of interstitial cells and fibroblasts in the interstitial tissue of the testis. In this experiment, cadmium chloride (4 mg/kg of body weight) administered to the adult male rats(Sprague-Dawlcy) intraperitoneally and sacrificed 1 week after treatment. And electrophoresis, immunoprecipitation and Western blotting, and N-terminal analysis were performed to find the proteins changed after cadmium treatment in the testis. And the results were as follows; 1. Two proteins of molecular weight 42kDa and 21kDa disappeared after cadmium treatment. 2. The protein of 2lkDa was rat collagen type I alpha 2. According to the above results, it was considered that cadmium degraded the collagen fibers within the wall of small blood vessels in seminiferous tubules and interstitial tissues and disrupted vascular walls, which resulted hemorrhagic necrosis, death of all the spermatogenic cells, and the death of interstitial cells and fibroblastic cells.
