  • This is the result of the comparison of the number of jeans, colors, images, opinions when it was purchased, shapes according to the gender of persons in jeans. According to the gender, male students had 1.64 jeans(46.3%) and female students had 2.09 jeans(53.7%) on the average. Male students selected colors of jeans which they don't have, but want to wear once in the order of blue(3.7%), red(21.0%), white(24.1%), black(25.6%), and others(25.6%). Female students selected colors in the order of blue(3.2%), black(15.6%), red(24.8%), white(27.7%) and others(25.6%). In case of the general image about jeans, male students thought the jeans as masculine(1.2%), sexy(3.1%), unisexual(3.2%), active(23.6%), young(29.8%), and comfortable(36.5%) and female students thought it as masculine(0.3%), sexy(3.5%), unisexual(10.4%), young(21.9%), comfortable(28.1%) and active(35.8%). Male students considered torn or holed jeans ill-mannered(10.7%), delinquent, (20.7%)trendy(21.0%), comfortable(22.9%), and dandy(24.7%). Female students think it ill-mannered(3.4%), delinquent7.1%, trendy(17.4%), comfortable(21.1%), and dandy(50.9%). When they purchase jeans, male students choose according to trends(17.9%), don't consider design(19.5%) and look for their own styles(62.6%), female students didn't consider design(5.2%), choose according to trends(22.0%), and look for their own styles(72.5%). The designs of jeans which they usually wear were bell bottom(1.5%), wide-shaped(7.4%), baggy(17.5%), straight-shaped(73.6%) in case of male students. on the other hand, in case of female students, baggy(10.2%), wide-shaped(11.0%), bell bottom(17.0%), and straight-shaped(61.8%). The designs of jeans which they didn't have but want to wear once are wide-shaped(10.1%), bell bottom(13.2%), baggy(20.9%), and straight-shaped(55.2%) in case of male students. On the other hand, females students want to wear baggy(11.6%), wide-shaped(15.0%), straight-shaped(27.6%), and bell bottom(45.8%). The above-mentioned findings illustrated that both male and female students regarded blue as the original color of jeans, but they wanted to wear jeans in colors other than blue. In the past, jeans were considered masculine and unisex, but they viewed jeans as an apparel that was comfortable to wear and made it easier to move. Female students had a higher tendency to be fashionable than male students, and their preference for jeans was consequently different. Jeans manufacturers should take those characteristics into account to produce products in different colors and form.

  • This study focuses on improving MIMO-OFDM systems by combining a wireless communication architecture known as vertical BLAST(bell laboratories layered space-time) or V-BLAST and STTC(space time trellis coding). In this paper, the combination is done by introducing STTC in each V-BLAST layer. Moreover, this architecture uses multiple antennas that are grouped into small number of antennas which makes it less complex to decode by decoding every group. Whereas, in traditional V-BLAST, all the antennas form one group and they are decoded together at the receiver, therefore, this increases the complexity as the number of antennas is getting high. We compare the bit error rate performance of this system with MIMO-OFDM that uses convolutional coding instead of STTC. Under the same spectral efficiency, the simulation results prove that joining V-BLAST with STTC improves MIMO-OFDM systems performance.

  • Purpose: The aim of this study was to analyze the elementary schoolchildren's the fear of crime in pedestrian environment of elementary school for providing the basic design resource. Method:In order to deal with that, the questionnaire survey on the elementary schoolchildren's the fear of crime were conducted in 5 elementary schools in Ilsan new town. The results of the 293 questionnaires survey were analyzed through SPSS program. Result: The main results were as follows. The level of fear of crime in pedestrian environment differed in these 5 elementary schools because of the width of pedestrian path, the concealed place around pedestrian path, the nearness of park, the height/shape/interval of trees, the number of car and the closure-watching in the school caused by fence and trees and so on. The level of fear of crime in pedestrian environment differed between that of boy groups and that of girls groups because of the number of emergency bell/telephon, the shape of pedestrian path, the number of security office, the number of car and the concealed place around pedestrian path and so on.

  • Objectives : Bell's palsy is the most common acute facial paralysis but its causes still unclear. At present, one of the most widely accepted cause is viral infections, and generally socioeconomic factors influence the viral infections. The purpose of this study is to investigate the relationship of incidence of facial palsy with socioeconomic factors. Methods : Seventeen patients with a acute facial palsy, who volunteered and completed all of the assessment measures participated. Using data on 17 participants, we examined the independent contribution of education, income, and occupation to a risk factor of severe facial palsy. Severity of global facial impairment was assessed by the facial disability index (FDI), the house-brackmann facial nerve grading system, WHO quality of life - bref (WHOQOL-BREF) and visual analogue scale (VAS) about discomfort of life. Results : There was no correlation between severity of facial palsy and gender, marriage, education, or occupation. Age greater than 60 years (p<0.05), and low monthly income(p<0.05), poor self-rated health was associated with greater severity of idiopathic facial paralysis. Conclusions : The number of subjects with facial palsy in our study (n-17) was small, and therefore generalization to larger patient populations might be unwarranted. But according to the outcome, we suggest that socioeconomic factors, especially low monthly income influence severity of bell's palsy.

  • The osteonectin is a sort of glycoprotein which is secreted in human tissues. The osteonectin is generally detected in number of normal or neoplastic human tissues in vivo, but hasn't been studied the role of osteonectin in developing human teeth and odontogenic tumors. We evaluated degree of the expression of osteonectin immunohistochemically in 20 cases of developing tooth germ which growth from fetus 5 to 38 weeks, and total 51 odontogenic tumors whitch has taken from routine biopsy, such as 10 ameloblastomas, 5 cases of adenomatoid odontogenic tumors and odontomas and odontogenic fibromas, 4 cases of cementomas and calcifying epithelial odontogenic cyst and odontogenic keratocyst and dentigerous cysts and periapical cysts, and 3 cases of ameloblastic fibromas and myxomas. The results were as follows: 1. The osteonectin on the bud stage of tooth germ was strongly expressed in the epithelial dental lamina and in the outer dental epithelium on the early bell stage, and also strongly expressed in the inner dental epithelium on the late bell stage of tooth germs. 2. In ameloblastoma, the osteonectin was strongly expressed in the epithelial tumor component and especially in the acanthomatous types. 3. In both of calcifying epithelial odontogenic tumor and adenomatoid odontogenic tumors, the osteonectin was moderately expressed on the duct like spindle cells and epithelial tumor cells around calcification areas. 4. In odontogenic tumors originated from epithelial-mesenchymal tissues, the osteonectin was moderately expressed on the epithelial tumor components and in odontogenic cysts, it was expressed in ghost cells and calcification areas only. These were summaried the osteonectin may be strongly related to the developing tooth germ and odontogenic tumors and could be regulated hard tissue of human tooth in morphogenesis and involved with calcification mechanism in development odontogenic tumors.

  • Tobamoviruses are the major viral pathogens of tomato and bell pepper. The preliminary results showed that Acibenzolar-Smethyl(ASM; S-methylbenzo(1,2,3) thiadiazole-7-carbothiate) pre-treatment to tomato and tobacco plants reduces the concentration of Tomato mosaic tobamovirus(ToMV) and Tobacco mosaic tobamovirus(TMV) in tomato and bell pepper seedlings, respectively. Pre-treatment of the indicator plant(Nicotiana glutinosa) with the ASM followed by challenge inoculation with tobamoviruses produced a reduced number and size of local lesions(67 and 79% protection over control to TMV and ToMV inoculation, respectively). In order to understand the mechanism of resistance the gene expression profiles of antiviral genes was examined. RT-PCR products showed higher expression of two viral resistance genes viz., alternative oxidase(AOX) and RNA dependent RNA polymerase(RdRp) in the upper leaves of the ASM-treated tomato plants challenge inoculation with ToMV. Further, the viral concentration was also quantified in the upper leaves by reverse transcription PCR using specific primer for movement protein of ToMV, as well as ELISA by using antisera against tobamoviruses. The results provided additional evidence that ASM pre-treatment reduced the viral movement to upper leaves. The results suggest that expressions of viral resistance genes in the host are the key component in the resistance against ToMV in the inducer-treated tomato plants.

  • Background: The infusion rate is considered to affect incidence and severity of infusion reactions (IRs) caused by protein formulations. Trastuzumab (TRS) is approved for 90-minute infusion as the initial dose followed by 30-minute infusion with 250 ml saline. In the study, we evaluated the safety of TRS intravenously administered over 30 minutes with 100 ml saline to reduce burden of patients, safety of infusion with 250 ml saline already being established. Materials and Methods: Women with HER2 positive breast cancer, ${\geq}18$ years and ${\geq}55%$ left ventricular ejection fraction (LVEF), were registered in the study. Patients received 8mg/kg of TRS 250 ml over 90 minutes followed by 6mg/kg of TRS 100ml over 30 minutes in a three-week cycle. Results: A total of 31 patients were recruited, 24 for adjuvant therapy and seven with metastases. The median age was 59 years (range 39 to 82). The total number of TRS doses ranged from 5 to 17 with the median of 15. Mild IR occurred in two patients at the first dose. However, no IR was observed after reducing to 100 ml saline. No decrease of LVEF, increase of serum brain natriuretic peptide or any other adverse events were reported. Conclusions: Intravenous infusion of TRS with 100 ml saline over 30 minutes in breast cancer patients can be considered safe based on results from the study. It can be given on an outpatient basis as with the currently recommended dilution in 250 ml saline.

  • The awareness of ritual foods in general rituals were surveyed and compared in the Gyeonggi and Gyungsangbuk-do areas in order to identify the characteristics of Korean rituals and establish desirable ritual foods. As materials for "Jeon" (fried pan cakes) in rituals, fish fillets, meat and vegetables were largely used in the Gyeonggi region. In the Gyeongbuk region, all three of these ingredients were the most highly used for "Jeon" also. In the case of rice cakes, "Songpyun" steamed on a layer of pine needles, "Jeolpyun" and "Sirudduk", with a red beans, were mostly used in Gyeonggi-do, while "Songpyun", "Jeolpyun" and "Ingelmi" were largely used in Gyeongsangbuk-do. As seasoned vegetables and herbs, fernbrakes, root of bell flowers, green bean sprouts and bean sprouts were largely used in Gyeonggi-do region, whereas, fernbrakes, bean sprouts, root of bell flowers and spinaches were mainly used in Gyeongbuk region. The use of fernbrakes was highest in both regions. With regard to the number of side dishes, 2∼3 kinds of seasoned herbs and 3∼4 kinds of fruits were mostly used, but with slightly higher numbers in the Gyeongsangbuk-do than the Gyeonggi-do region. With regard to liquor used for rituals, clear strained rice wine was used most in the Gyeonggi-do area, while more unrefined rice wine was used in the Gyeongbuk region. Meat was the most used ingredient in broth slices of dried meat and cod were highly used in the Gyeonggi region, but slices of dried squid were most widely used in the Gyeongbuk region. Most households in both regions tended not to use raw fish in the rituals, and as for the ingredients of Korean Kabobs, meat was the most widely used, then fish and finally vegetables were the most used ingredients. Beef soup was the most used, but more green vegetable soup was used in the Gyeongbuk than the Gyeonggi region. Sweet drink made from fermented rice (sikhe) was generally used in the rituals. It was the most widely used in the Chusok-Hangawi Ritual in the Gyeonggi region, while it was used in the New Year's Ritual in the Gyeongbuk region.
