  • The purpose of this study was to be a help with designing science curriculum and developing science programs for the science gifted students by comparing their preferences about science class forms and class environments between science gifted students and normal students. For this study, 2 classes of science gifted students and 5 classes of normal students in 4th, 5th grade joined in this survey and their preferences about science class forms and class environments were checked using questionnaire. As a result, the following findings were obtained. First, in the area of class form, from comparing their preferences about teaching content domain, science gifted students showed meaningful higher preferences in all factors such as clarification, structuralization, thinking of high level and diversification. In comparing their preferences about teaching process domain, science gifted students also showed meaningful higher preferences in all factors such as diversification and self directed learning. Second, in the area of class environment, from comparing their preferences about classroom domain, science gifted students showed meaningful higher preferences in all factors such as teacher's support and rule and organization. In comparing their preferences about mentality domain, science gifted students also showed meaningful higher preferences in all factors such as influence of friends and parents. Third, in science gifted students, from comparing their preferences by gender about science class forms and class environments, female students showed meaningful higher preferences in factors of clarification. And in other factors females showed similar preference tendency with male students. In normal students' comparing, female students showed meaningful higher preferences in factors of teacher's support. And male students showed meaningful higher preferences in factors of high level thinking and influence of friend and influence of parents.

  • The present studies were undertaken in attempt to investigate the preventive effect of $\beta$-glucan from barley ad diltiazem on cholesterol and vitamin D2 induced-atherosclerotic rat. The results obtained were summerized as follows. 1.The group, fed only the mixture of cholesterol and vitamin D2, showed significant increase of calcium, inorganic phosphorus, total cholesterol, lipid LDL-cholesterol and phospholipid in serum, and total lipid in the liver (p<0.05) as comparing with normal group. The aorta showed severe damage of disorganization, necrosis and lipid deposition in the elastic membrane. 2. The group fed mixture of cholesterol and vitamin D2 plus diltiazem simultaneously, showed significant increase of total cholesterol, total lipid and phospholipid in serum, and total lipid and triglyceride n the liver (p<0.05) as comparing with normal group, but the significant decrease of calcium and inorganic phosphorus in serum(p<0.05) as comparing with the atherogenic control group. The aorta showed slight damage of elastic membrane and lipid deposition as comparing with the atherogenic control group. 3.The group, fed mixture of cholesterol and vitamin D2 puls $\beta$-glucan simultaneously, showed significant decrease of total cholesterol, LDL and VLDL-cholesterol, total lipid, phospholipid and triglyceride in serum, and total lipid in the liver as comparing with the atherogenic control group(p<0.05), but the significant increase of calcium in serum as comparing with the normal group(p<0.05). The aorta showed no changes in elastic fiber and no lipid deposition in comparing with the atherogenic control group.

  • Consider a situation that a specific treatment is regarded as the best in comparing several treatments. In this case, a natural procedure to decide the best treatment is to choose the specific one which is proved to be better than each one of the others. This study proposes a method for detecting the best by comparing two treatments from the above point of view. Since this method deals with comparing only two treatments, it is very simple to use and expected to be widely applicable.

  • (1) By comparing and analyzing the distribution of brightness as domestic lamps and Japanese products go thinner and lighter, we set an effective design standard. (2) By comparing and analyzing the feature, brightness, chromaticity and uniformity of domestic LGPs and Japanese products, early home-manufacturing and stabilization in home-manufacturing are possible. (3) By comparing and analyzing the distribution of brightness as sheets are varied, we can design an ideal sheet composition.

  • Objectives : There are numerous methods in treating acne scar. On the contrary there are hardly any cases on treating acne scars through Korean medicine. By observing we compared how much acne scar was treated by scar regeneration acupuncture therapy and micro-needle therapy treatment through observing pre and post case photos, KAGS, KCADI and patient satisfaction. Results : By comparing pre and post procedure through acne scar grade criteria, total of 5 patients showed improvement and could see distinct change in skin comparing case photos. After comparing pre and post procedures, total of 5 patients showed improvements in figures of Korean acne index. 4 patients replied very satisfied and 1 replies satisfied on patient satisfaction survey. Conclusions : After observing patients satisfaction, and comparing case photos, acne scar grade criteria, korean acne index, it can be considered that scar regeneration acupuncture therapy and micro-needle therapy done in our clinic to be valid treatment.

  • Object-based image retrieval method is addressed. A new image segmentation algorithm and image comparing method between segmented objects are proposed. For image segmentation, color and texture features are extracted from each pixel in the image. These features we used as inputs into VQ (Vector Quantization) clustering method, which yields homogeneous objects in terns of color and texture. In this procedure, colors are quantized into a few dominant colors for simple representation and efficient retrieval. In retrieval case, two comparing schemes are proposed. Comparing between one query object and multi objects of a database image and comparing between multi query objects and multi objects of a database image are proposed. For fast retrieval, dominant object colors are key-indexed into database.

  • In recent years, new construction methods have been required to reduce the construction cost and increase the available area in an environment where construction work is frequently performed in a narrow urban area like Korea. As a result of these studies, slim floor composite beam has been suggested. Slim floor composite beam can reduce required depth because web of steel beam is embedded in the slab, so it is effective to reduce floor height and increase the available area. The purpose of this study is the floor height reduction evaluation by comparing system consisting of reinforced concrete, steel, and slim floor using square-shape steel pipe. After doing structural design for a typical plan, checked effectiveness by comparing each design plan. It is proven that slim floor composite beam can reduce required depth effectively comparing required materials of other system.

  • This study was aimed to evaluate the anti-stress effect of danchisoyosan on the rats stressed by immobilization. The experimental animals were immobilized in the stress box($5{\times}5{\times}20cm$) for 12 hours in a day during 3 days, and administered $500mg/5m{\ell}/g$ of Danchisoyosan extract for 14 days before stress. There were measured the change of body weight and organ weight under immobilized-stress. The norepinephrine, epinephrine, dopamine, serotonine contents were measured by HPLC method in rat brain. There were measured the GOT, GPT contents in serum and tissue lipid peroxidation in the brain, liver, spleen, adrenalgland, pancreas, testes, thymus, heart. The following results were obtained: 1. The change of organ weight was significantly lower in control than normal group. Sample group inhibited decreased weight from stress comparing to control group. 2. Lipid peroxidation in the liver was significantly higher in control than normal group. Sample group shows significant decrease comparing to control group. 3. Lipid peroxidation in the kidney was significantly higher in control than normal group. Sample group shows significant decrease comparing to control group. 4. GPT contents in serum was significantly higher in control than normal group. Sample up shows significant decrease comparing to control group. 5. Dopamine contents in the brain was significantly higher in control than normal group. Sample group shows significant decrease comparing to control group. 6. Serotonine contents in the brain was significantly higher in control than normal group. Sample group shows significant decrease comparing to control group.
