미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

The third generation cephalosporin is widely used in treatment of spontaneous bacterial peritonitis (SBP). Resistance to the third generation cephalosporin was associated with poor outcome in patients with SBP. Thus it is necessary to know the changes in resistance rate. We planned to investigate retrospectively on resistance rate of the third generation cephalosporin of gram negative bacteria isolated in patients with SBP, who visited Seoul National University Hospital between 1998 and 2006. The Clinical and Laboratory Standards Institute guidelines were applied for antibiotic susceptibility test. A total of 269 consecutive episodes of clinically and microbiologically proven SBP was identified during the study period and 209 cases were caused by gram negative organisms. Among 209 isolates, 22 (10.5%) showed resistance to the third generation cephalosporin. The prevalence of resistance was decreasing during the study period (P=0.014).

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

Traditional houses as cultural assets are required to preserve their original forms, which could conflict with residents' demand for higher living standards. These houses were built with sustainable structure and material that can contribute to natural environmental control of building. Nevertheless, their thermal environment seem to be inferior in modern living standards and improvements are certainly necessary. The aim of the study is to evaluate the effects of the building improvements on the energy performances of a traditional house. In this study, the simulation program of Visual DOE 3.1 was used to predict annual heating and cooling energy loads of the house, and sensitivity studies were performed. The subject building in this study was a main building of Genjaegotaek, located at Oeam-maeul, Asan, Chung-Nam. The simulation results for that building indicated that the main determinants of the building energy loads were walls and openings(windows and doors): They represented about 50% and 41% of the annual heating loads, and 49% and 24% to the annual cooling loads, respectively. The improvements of wall and openings turned to be more effective in the house. Of the three measures of energy improvements, wall insulation is the most relatively important, followed by openings, and then ceiling insulation. The energy simulation was further performed with all three improvement measures, and the results indicated that the building heating and cooling loads decreased about 66% and 13%, respectively, and the total annual energy loads decreased by about 46%. This study addressed the issue of thermal improvements of traditional house through building energy simulations. Due to some unknown properties of building elements there are some limitations in modeling the traditional house, and more detailed information from surveys and experiments is needed for more reliable thermal modeling.

The age-hardening behavior of a commercial dental casting low-carat gold alloy was investigated by means of differential thermal analysis, hardness test, optical microscopic observation and X-ray diffraction study. The following results were obtained. 1. By the isothermal aging of this alloy at 300∼400℃, the hardness increased markedly at the initial stage and continued to increased gradually for the time, and then decreased dractically after longer aging time. 2. The hardening was attributed to the formation of the metastable AuCu I' ordered phase from the α matrix. 3. The overaging with softening was attributed to the precipitation of the fine lamellar structure which was composed of the Ag-rich α1 and AuCu I ordered phases.

쑥갓의 지상부를 MeOH로 추출하고, 추출물을 EtOAc, n-BuOH 및 물로 분배, 추출하였다. n-BuOH분획으로부터 silica gel 및 ODS column chromatography를 반복하여 배당체를 분리하였다. 화합물의 화학구조는, MNR 및 MS 등의 스펙트럼을 해석하여 1-o-β-D-glucopyranosyl-3-hexenol으로 동정하였다. The aerial parts of Garland (Chrysanthemum coronarium L.) were extracted in MeOH and solvent fractionated with EtOAc, n-BuOH and water, successively. n-BuOH fraction gave a glycoside compound through application of silica gel column chromatographies including ODS. The chemical structure of the glycoside was determined by the interpretation of several spectral data, including NMR and MS as O-β-D-glucopyranosyl-3-hexenol (1).

The purpose of this research is to obtain the data for quality control of recycled aggregates product and use by examine the correlations among physical properties of recycled aggregate made of crushed waste concrete. For this purpose, we tested the physical properties of 7 recycled coarse aggregates and 10 recycled fine aggregates according to Korea Standards. As a result, we proposed the correlation equations for physical properties of recycled aggregates. Although the correlations among physical properties of recycled fine aggregates and recycled coarse aggregates showed some quantitative differences, this research revealed their similar tendencies.
