  • Three patients who had Angle's Class II Division 1 malocclusion were treated by Bioprogressive therapy. In spite of their occlusions, the 3 patients did not have any skeletal problems. Their skeletal patterns were within normal range. So headgear or functional appliance therapy were not considered. During the treatment procedure, the most noteworthy results of Bioprogressive therapy were the effect of the Utility arch to intrude 4 mandibular anterior teeth, the effect of the Cuspid retractor in cuspid retraction and the effect of the Double delta retraction arch in the retraction of 4 anterior teeth. The whole treatment results in these cases which were achieved by Bioprogressive therapy were very favorable and the efficiency of this therapy was very excellent.

  • In this study, micro electrochemical machining method was introduced for accomplishment the fabrication technology of functional parts and smart structures using the Ni-Ti shape memory alloy. From the experimental result, the micro part which has very fine surface could be achieved by use of micro electrochemical process with point electrode method. Concretely, the optimal performance of micro electrochemical process in Ni-Ti SMA was obtained at the condition of approximately 100% of current efficiency and high frequency pulse current. That is, much finer surface integrity and shape memory effect can be obtained at the same condition mentioned above.

  • This research was carried out to investigated the effect of base paper and latex binder on printability and obtical properties of coated paper. Especially, it examined the effect of th pH of vase paper surface and functional groups of latices on the interactions between coating color components and on the structure of coated layer. It was found that the behavior of coating color containing amphoeric latex depends on the pH in the boundary region between coating color and base paper. Thus, the coating color formulated with amphoteric latex formed bulky coating layer by inducing stronger interaction between paper surface and coating components than the coating color with anionic latex. The coated paper with amphoteric latex showed better optical properties (i.e.gloss and optical) and printability (i.e. ink receptivity, wet ink receptivity, and ink set off) than the conventional anionic latex in the acidic and alkaline paper. However, dry pick strength of the coated paper was less decreased. This result indicated that amphoteric latex could also be applied practically to the alkaline paper.

  • Concrete which is a composite material is frequently used in construction works. Properties and behavior of concrete are significant under the effect of different loading cases. Impact loading which is a sudden dynamic one may have destructive effects on structures. Testing apparatuses are designed to investigate the impact effect on test members. Artificial Neural Network (ANN) is a computational model that is inspired by the structure or functional aspects of biological neural networks. It can be defined as an emulation of biological neural system. In this study, impact parameters as acceleration and impact force values of a reinforced concrete slab are obtained by using a testing apparatus and essential test devices. Afterwards, ANN analysis which is used to model different physical dynamic processes depending on several variables is performed in the numerical part of the study. Finally, test and predicted results are compared and it's seen that ANN analysis is an alternative way to predict the results successfully.

  • Phellinus linteus was examined on its immunostimulating activities using an in vitro imunization and plaque forming cell assay. When lymphocytes were exposed to the extract of Phellinus linteus, the number of antibody forming cell was increased. In in vitro plaque forming cell assay, the immunostimulating effect was about 4.8 and 5.0 times of unimmunized control in polyconal and T-independent antibody response, respectively. Especially, Phellinus linteus significantly increased the antigenicity of TNP-LPS used as T-independent antigen. But Phellinus linteus did now show a mitogenic effect on B-lymphcytes. These results suggest that immunostimulating activity of Phillinus lintues might be associated with a functional stimulation of B-lympohocyte involved in humoral immune response.

  • The stabilizing effect of fructooligosanharide (FO) on hen's egg yolk immunoglobulin (yIgG) by heat and acid was investigated. The heat stability of yIgG at 70∼80$^{\circ}C$ was enhanced in a concentration-dependent manner by adding 0∼50% (w/v) FO to a yIgG solution. Acid-induced inactivation of yIgG was also suppressed in a concentration-dependent relationship by addition of FO. Addition of 50% FO almost completely stabilized yIgG at pH 3. The remarkable stablizing effect of FO on yIgG may enhance the use of yIgG as functional food ingredients.

  • Re purposes of this study were to determine consumers' selection criteria of fashion shopping area and to examine the effects of clothing consumption value and fashion leadership on the selection criteria of fashion shopping area. In addition, the third purpose was to clarify the relation beかeon the above variables and shopping intent. The data were collected from 198 females in their twenties using questionnaire. The results could be summarized as follows. First, the selection criteria of fashion shopping area were composed of 5 factors: scale & variety of shopping area, convenience of location, entertainment, physical service, and atmosphere. Second, the fashion leadership and clothing consumption value except functional and social values had an effect on the selection criteria fashion shopping area. Particularly, the attractiveness-sought value best explained the selection criteria. Third, the fashion leadership and selection criteria fashion shopping area had an effect on the shopping intent. The effect clothing consumption value was not significant.

  • The purpose of this study was to develop the antiallergic and hypoallergic fennented soybean foods without side effect. We manufactured Chungkukjang with addition of herbal (aloe, cinamon, licorice root) extract. Sensory evaluation was performed to evaluate the acceptability by the consumer. Clinical evaluation was performed with 10 atopic dermatitis (AD) patients who showed positive reaction with specific IgE and skin prick test. Cross-over study between nonnal Chungkukjang and Chungkukjang with aloe extract was performed. In sensory evaluation, Chungkukjang with aloe extract obtained best score overall. In clinical evaluation, 7 out of 10 AD patients showed positive reaction to soy-bean and 4 out of 10 AD patients showed positive reaction to normal Chungkukjang. 2 out of 10 AD patients showed positive reaction to Chungkukjang with aloe extract. In conclusion, Chungkukjang could be recommended as functional food with hypoallergic effect. As adding aloe extract to Chungkukjang, hypo allergic effect was increased.

  • An electromagnetic memory effect observed in superconducting YBCO system was studied. From the measurement of differential conductance, it was cleared that the mechanism of electromagnetic memory can not be explained by using conventional flux flow model. By changing the density of external magnetic flux, changes in inductance of a coil in which a superconducting bar is inserted were also measured. It was concluded that the electromagnetic memory effect aries from the interaction between the trapped magnetic flux and the weak link of the filament formed in the superconducting bar.

  • The purpose of this study was to examine the effect of consumption values on well-being attitude and the effect of well-being attitude on well-being oriented behavior. This study administered a questionnaire survey to adults between 10s and 60s who lived in Seoul, Daegu, and Kyungbuk region. Data collected from 285 respondents were analyzed by descriptive statistics, t-tests, ANOVA tests, factor analyses, and structural equation modeling (SEM). The model of the study was tested by structural equation modeling and the results of SEM revealed positive effects of social value and functional value on well-being attitude and positive effect of well-being attitude on well-being oriented behavior. The results of t-tests and ANOVA tests showed that there were significant differences in consumption values, well-being attitude, and well-being oriented behavior among marital status, age, educational level, and income level groups.
