Slow pyrolysis of sawdust was performed in semi-batch reactor to produce bio-char, bio-oil and bio-gas. In bio-oil, there are a variety of chemical compounds. Leading aromatic chemicals such as furfural, creosol and catechol were a focus of this study. under experimental conditions, the slow pyrolysis temperature were 350, 400, 450, 500, and 550 ℃. Maximum bio-oil yield of 39.3% at 500 ℃. The peak area of furfural, which is a valuable organic chemical, was highest value at 400 ℃. To separate of complicated bio-oil into similar functional group, liquid extraction method was used through various non-polar solvent (n-hexane, toluene, diethyl ether). The result analysis evaluated the mass yield of bio-oil and GC-MS data for quantitative and qualitative analysis.
An ESP Course for Nursing College Students
Eun-jung Kim 한국응용언어학회 2008 응용 언어학 Vol.24 No.3
The requirement for successful communication skills in English has increased with the overall trend towards globalization and the growth of international medical development and healthcare specialization in recent years. Logically, ESP course design should proceed by identifying the target situation first, and the concomitant needs of target learners. Building a language course on these factors would lead to stronger practical language skills that will enable student nurses to function effectively in future real-world situations. In this study, therefore, prior to the design of an ESP program for nursing college students, a target situational needs analysis was conducted by applying a triangular approach to obtain valid information from different sources and methods (Long, 2005). by examining nursing students" needs to identify target language learning objectives, this study attempts to provide a balanced picture of ESP curriculum.

This study analyzes how invisible social capital, expressed as the parent-child relationship, interacts with financial (family income) and human capital (fathers’ educational level) within a home and on a child’s self-esteem. The subjects of the research are 3509 Korean middle school students in the 2nd grade, who acted as the panel for the 1st year of the Korean Youth Panel Studies, in 2004. That longitudinal study was carried out from 2003 to 2008 by the Korean Institute for Youth Development. As a result of comparing two models, one that included social-capital variables (the parent-child relationship) and one that did not, this study found that economic and social status positively influenced self-esteem in adolescent children, but the effect was indirect. The effect of financial and human capital was instead attained through close interaction between parents and children. This study also confirmed that among social-capital variables, parent-child communication has a comparatively great effect on the formation of self-esteem in children.

Background/Aims: We aim to evaluate the association be-tween promoter polymorphism of the clusters of differentia-tion 14 (CD14) gene and Helicobacter pylori-induced gastric mucosal inflammation in a healthy Korean population. Meth-ods: The study population consisted of 267 healthy subjects who visited our hospital for free nationwide gastric cancer screening. Promoter polymorphism at -260 C/T of the CD14 gene was determined by polymerase chain reaction and re-striction fragment length polymorphism analysis. The severity of gastric mucosal inflammation was estimated by a gastritis score based on the sum of the values of the grade and activ-ity of the gastritis. Expression of soluble CD14 (sCD14) was assessed by quantitative sandwich ELISA. Results: CD14 polymorphism was not associated with H. pylori infection. There were no significant differences in gastritis scores among the genotype subgroups, but subjects carrying the CD14 -260 CT/TT genotype had significantly higher sCD14 levels than those carrying the CC genotype. Subjects with the 260-T allele of the CD14 gene and H. pylori infection had significantly higher sCD14 levels than those with the same genotype but without infection. Conclusions: In individuals with the T allele at the -260 site of the promoter region of the CD14 gene, H. pylori infection accentuates gastric mucosal inflammation.
Fus Expression Patterns in Developing Tooth
Eun-Jung Kim,Jong-Min Lee,Han-Sung Jung 한국발생생물학회 2013 발생과 생식 Vol.17 No.3
Recently, the RNA/DNA-binding protein FUS, Fused in sarcoma, was shown to play a role in growth, differentiation, and morphogenesis in vertebrates. Because little is known about Fus, we investigated its expression pattern in murine tooth development. In situ hybridization of mouse mandibles at specific developmental stages was performed with a DIG-labeled RNA probe. During early tooth development, Fus was detected in the dental epithelium and dental mesenchyme at 11 days postcoitum (dpc) and 12 dpc. From 14 dpc, Fus was strongly expressed in the dental papilla and the cervical loop of the dental epithelium. At postnatal day 4 (PN4), Fus expression was observed in the odontoblasts, ameloblasts, the proliferation zone of the pulp, and the cervical loop. At PN14, the expression pattern of Fus was found to be maintained in the odontoblasts and the proliferation zone of the pulp. Furthermore, Fus expression was especially strong in the Hertwig’s epithelial root sheath (HERS). Therefore, this study suggests that Fus may play a role in the HERS during root development.

The aim of this study was to investigate the effects of foot position adjuster on body alignment and weight loads in chronic stroke patients. The subjects were 15 chronic stroke patients who were admitted to KHospital in Daegu, South Korea. The study compared the body alignment and weight load changes on flat ground with the foot position adjuster using Foot scan and Dartfish video analysis software. In the results of this study, posterior superior iliac spine (PSIS) alignment decreased significantly after use of the foot position adjuster and center pressure was significantly increased after use of the foot position adjuster. This study suggests that foot position adjuster influences body alignment and weight distribution.
