Researches on the steel-concrete composite girder filled with plain concrete have been being actively performed on the grounds that this type of girder has constructional, structural and aesthetical benefits. As a part of studies on the characteristics of inner shear connections in the concrete-filled steel-concrete composite girder with plain concrete, the confinement effect on the stiffness of inner shear connections was examined in this study. In the case of concrete-filled steel-concrete composite girder, it can be expected that the stiffness of shear connections may be increased in comparison with the case not confined. Therefore, the experimental studies were performed with the confinement effect as a parameter, and the results are discussed in this paper.

The objective of this paper is to construct a model to be used in deciding whether to repair or rebuild school buildings is depending on their ages and other factors. The theme of this paper is the age is the main variable but other factors such as floor, innerwall, ceiling, door, inner window of the class room, outer window of the class room, inner window of the corridor, outer window of the corridor, middle window between the classroom and the corridor, light, heater, speaker, fire protection sensor, TV monitor, and telephone status would influence the final decisions. This paper employs an experimental case study method. Using the stepwise, statistical, classification method commonly used in discriminant analysis, it evaluates 12,766 rooms of 87 different high schools in Seoul. The result of this study indicates that some critical variables influencing the final decisions are the status of TV monitor, middle window between the classroom and the corridor, light, inner window of the corridor, fire protection sensor, innerwall, speaker utensil, outer window of the class room, and door of the class room. This paper also suggests a linear discriminant function will be used for this kind of studies. Finally the paper recommends policies with respect to the variables and discriminant functions evaluated.

In case manufacturing COF, through hole should be made to be used for a pathway connecting the conductive layers of its both faces. In case Cu-plating inside of through hole with electroless plating way, contact between Cu and PI film gets bad to be fell apart from PI by the impact of applying to the electric devices. Therefore, after sputtering is applying on inner through hole, then a method to perform electroplating process. In this study, after changing sputtering condition to manufacture FCCL, we looked the changeability of the upper PI and inner hole Cu layers. Making use of RF Magnetron sputtering equipment, we coated Cu thin film and Cu-plated on it through electroplating. After cold-mounting the completed FCCL, we examined hole section through an optical microscope. From the result of test, with parameters deposition pressure and deposition time, both the thickness of the hole plated layer and PI plated upper layer increased at regular rate, increasing the thickness of Cu sputter layer. However, from the result of test in increasing RF-power, we could know the increment rate of hole plated layer is considerably greater than that of PI plated upper layer. Therefore, we finally acquired good result; if you want only to increase the plated layer of inner hole, it's much better to increase RF-power.

The surface region of a sheet metal may have different characteristics from the inner region because the surface region is less restricted than the interior. In addition, the grains on the free surface are less hardened because of surface adsorption of the dislocations, rather than piling up. In the case of bulk or thick sheet metals, this effect is negligible because the fraction of the surface region is much smaller than that of the inner region. However, this surface effect is important in the case of ultra-thin sheet metals. In order to evaluate the surface effect, tensile and bending tests were performed for the SS304 stainless steel with a thickness of 0.39 mm. The bending force predicted using the tensile behavior is higher than the measurement because of the surface effect. To account for the surface effect, the surface layer model was developed by dividing the sheet section into surface and inner layers. The mechanical behaviors of the two regions were calibrated using the tensile and bending properties. The surface layer model reproduced the bending behavior of the ultra-thin sheet metal.

This study examined fashion through the lens of Charles Taylor's concept of 'Authenticity.' From the point of view of 'Authenticity,' fashion can be thought of as "a means of expressing one's inner truth" and "affirmative about everyday life." According to 'Authenticity,' fashion, in the first case ("one's inner truth") appears as 1) magnetic uniqueness, 2) inner subjectivity, and 3) poiēsis. And in the second case ("affirmative about everyday life") it is expressed as 1) naturalism, 2) positivity of self-expression, and 3) existentiality. For this study, we selected a high school 'ganzi' contest, whose participants were deemed to have a high level of interest in and understanding of fashion, compared to other teenagers living in South Korea. Among the 33 participants in 'Goganzi' Seasons 1 and 2, we analyzed the styles and looks of 30 works by the six people who made it to the final stage. As a result, we broke down the aesthetic values of authenticity that teenagers express through their fashion into three categories: plurality, originality, and creativity.

Objectives: The purpose of this research was to find out the efficacy of Castanea crenata Inner Shell (CCIS) distilled herbal medicine on the skin by comparing the difference effect between only simple distilled water and the CCIS distilled herbal medicine application after MTS (microneedle therapy system) treatment. Methods: The present author performed once a week and total 4 times of MTS treatment. The treatment time took about 5~10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, simple distilled water was applied after MTS and in the experimental group, CCIS distilled herbal medicine was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results: In the case of the test group, there was a significant decrease in pore size and there was a significant increase in U-zone oil, skin tone and elasticity. The test group using distilled herbal medicine showed a significant effect on facial skin compared to the control group using only simple distilled water. Conclusion: Distilled herbal medicine showed an effective action on facial skin. In the case of CCIS distilled herbal medicine, it was found to have a significant effect on U-zone oil content, skin tone, pores, and skin elasticity.

This paper aims at exploring how a high school student is engaged with C computer programming language and explore deep aspects of programming experiences based on video recalled interview as part of portraiture. The single case was selected and several in-depth interviews and video recording were arranged after Oct 2011. The portrait of K reveals interesting strands of his computer programming experiences with his own thinking patterns and exploring ideas for more concrete ways of coding his thinking similar to scientific experiments; ie, design-development-implementation-debugging-revision. Overall, this case illustrates how the inner aspects of subjective programming experiences on the tower of Hanoi were integrated and unified within himself for inner growth. We discussed the student's inner faculties as part of the student's unity and suggested future research direction.

This paper provides a numerical solution for multiple confocal elliptic dissimilar cylinders. In the problem, the inner elliptic notch is under the traction free condition. The medium is composed of many confocal elliptic dissimilar cylinders. The transfer matrix method is used to study the continuity condition for the stress and displacement along the interfaces. Two cases, or the infinite matrix case and the finite matrix case, are studied in this paper. In the former case, the remote tension is applied in y- direction. In the latter case, the normal loading is applied along the exterior elliptic contour. For two cases, several numerical results are provided.

This study analyzed features of elements that compose a logo of inner wear brands to get the following results: First, it was found that "elegance" was the most frequently used word to express the concept of inner wear brands to be followed by words like dignity, high-end and aristocratic, words emphasizing femininity, such as feminine, romantic and sexy, words emphasizing practicality, such as convenient, practical, modern, functional and reasonable, and words emphasizing hygiene, such as clean, healthy and hygienic. This suggests that consumers nowadays pursue image more than functional aspects in the shopping of inner wear and consumers' pursuit of such values is reflected in the concept of inner wear brands. Second, unlike logos for outerwear brands that generally used initials of brand name, word-type logos for inner wear brands used the full name of brands, thus suggesting that they put more emphasis on delivery of information rather than on the symbolic aspect. In case of combining characters with concrete objects, they were found generally to use objects that give an soft, elegant and feminine image, such as flowers, woman's head and ribbons. Third, colors in the series of pink and red seemed to be used to convey the concept of inner wear brands that pursue such images as romanticism, femininity, elegance and sensibility, while colors in the series of blue, black and grey for such concepts as functionality, practicality, simplicity, health, hygiene and refinement. With reference to typeface used in the design of logos, unlike outerwear brands of which 83% use sans serif typeface for logos, relatively high percentage of inner wear was found to use typefaces of serif series to stress feminine flexibility and delicacy and give the image of elegance and classical tenderness. With reference to language used in logo naming for inner wear brands, 33 brands were found to use English and only three brands used Korean among the 36 brands surveyed. Even with inner wear brand logos that have Korean name, it was found that they used English in the use of logo marks. Like the result of previous studies, the result of this study indicates that methods to design brand logos for clothing should be incessantly sought in a way to build brand power as an important component to represent concept or function of brands and reinforce brand image.
