The purpose of this study is to develop a new makeup-kit brand for education, analyzing customer satisfaction of makeup-kits used in makeup lessons provided by lifelong education centers of colleges. The research method is as follows. In order to understand the current status of the kits used in makeup lessons offered by lifelong education centers of colleges in South Korea, the study conducted a survey from October 10 of 2014 to October 31 via fax, telephone and e-mail targeting these 98 colleges that were open makeup-courses available in October 2014. As for an analysis technique, the study used a frequency analysis. In order to develop a makeup-kit brand, the study investigated these makeup-kits as well and presented a BI draft and a makeup-kit design that the study had created for itself using Photoshop CS6 and Illustrator CS4. According to findings of the survey, the students were not satisfied with kits that had too many items, were high in price and had poor case design. In the light of that, the study conducted to develop a low to middle priced makeup-kit ranging from 110,000 KRW and 150,000 KRW with approximately 26 items. In terms of a case design, black was a dominant color which would make the case feel simple and modern. Dimensions of a small size makeup-kit container were 22cm*35cm*37cm with a sponge and rubber pad proposed as product ideas. The study also worked on a BI design.

The high-tech computer technology developments have greatly affected the area of design education. Starting from the mid 80s, innovations in visual presentation methods have heightened with 2D computer graphic programs, CAD & 3D modeling, and Rapid Prototype that allows dimensional generation. The specialty and quality in design studio education have advanced due to the development in presentation methods such as Power Point and Keynote. But there are many problems with the current method of presenting the visual outcome in a data format using beam projectors, which is a vertical presenting method compared to the old studio study method of conducting discussions and reviews based on the substantial outcome. The essence of studio study that allows for comparisons and analysis by horizontally opening up the various work outcomes is being offset. Also the requirement for manual idea sketching work that plays an important role in the initial design phase continuing to decrease due to the digital working process dependence and cumbersome procedures in the presentation. In order to resolve this problem, the CALM system (Class Applied LCD Modular System) has been developed that replaces the method of attaching the sketches or renderings on the wall with a digital multi-display system. In a nutshell, individuals will upload the outcomes online and display them on the CALM system studio that is composed of 32 LCD (Columns: 4 $\times$ Rows: 8) monitors that are 19 inches in size so that various personnel can openly study the design outcomes. Also the central 42 inch PDP monitor that offers touch pad capability allows each design outcome to be described and examined by expanding. The concept phase of this development process has elevated to the production of an operating prototype that is being reviewed of its practicality. It is considered that the development of this system will decrease the extreme tendency of depending on digital operation but achieve revitalization of a more realistic and opened studio study environment compared to the individual consulting method of the old study approach.

본 연구는 소비자가 지각하는 유통업체의 위치기반 모바일 쇼핑정보 서비스에 대한 정보의 상황관련성과 정보자극에 대한 PAD 감정변수들(환기, 지배력, 즐거움) 간의 상호 인과관계와 이용의도에 대한 이들의 효과를 실증 연구 하였다. 미국 내 모바일 이용자를 대상으로 무작위 표본추출법에 근거하여 추출되었고, 총 335명의 사용가능한 응답이 수거되었다. 분석결과, 환기와 상황관련성은 즐거움에 정(+)의 영향을 주었으나 지배력은 즐거움에 유의한 영향력을 나타내지 않았다. 즐거움은 이용의도에 정(+)의 영향을 주었다. 본 연구를 통해 위치기반 모바일 서비스에 대한 소비자의 인지적 반응과 감정적 반응을 통합적으로 살펴보았으며, PAD 감정차원간의 체계적인 관계를 규명하였다. 연구결과를 바탕으로 모바일 쇼핑서비스 개발자, 유통업체, 그리고 마케팅 실무자를 위한 시사점을 논의하였으며, 연구의 한계점과 더불어 향후 연구 방향을 제시하였다.

The railway bridge of the domestic still has been used steel base such as sperical bearing and pot bearing widely. However, the bearing of steel series is occured corrosion frequently, reduced durability and raised maintenance cost excessively due to the nature of the material. If the elastomeric bearing which is widely used in highway bridge is applied to the railway bridge, it will be able to compensate this defect a lot. In order to apply to the railway bridge used for highway bridge, is needed the control of the bridge ends deflection, lateral displacement and negative reaction. Therefore, the elastomeric bearing can be applied to the railway bridge enough, if installed negative reaction key for control of the bridge ends deflection, improved shear wedge performance for control of the lateral force, adjust the thickness of the elastomeric pad for the minimize deflection, in addition, can be economic design of sub-structures due to damping effect.

For sound absorption and sound insulation in automobile industry, the sound absorption materials based on meltblown nonwovens were prepared by SMS (spunbond-meltblown-spunbond) technique. And the sound absorption coefficient (${\alpha}$) of the meltblown nonwoven, produced with isotatic-polypropylene(PP), was examined for the various processing conditions such as die-to-collector distance(DCD), nonwoven weight(GSM), and air suction conditions. The meltblown nonwoven for sound absorption materials was composed of bulky microfiber web, increasing with increases in weight and DCD. The sound absorption coefficient(${\alpha}$) was excellent as a sound absorption materials of PAD type composed of SMS(spunbond-meltblownspunbond) nonwovens.

The machine equipment of the building inside occurs the vibration. In order to reduce this vibration spring, rubber pad is used. But efficiency of this classical mount is restricted at specific frequency. Also maximum efficiency design is complicated. This paper proposes and examines a attached mass isolation system that is used to reduce transmitted vibrations from machines onto their floor support. With attached mass the low frequency performance is improved overall. The performance is showed in 2 degree of freedom model test. And the proposed isolator has been validated by dynamic test and good agreement between theoretical and experimental results has been obtained.

We propose a new contact detection algorithm for fine pitch wire bonding. Fast and stable contact detection of the z-axis in wire bonding is extremely important to maintain the quality of fine pitch gold wire bonding processes, which use a small pad less than $70{\mu}m$ in diameter. A small perturbation in the contact detection time causes a large difference in the size of the formed squashed ball. The new detection method is based on a statistical approach and designed for a discrete Kalman filter. It is faster and has smaller detection time variations than conventional detection methods. Experimental results are presented to demonstrate the advantages of the proposed algorithm.

In this paper, an initial fine alignment algorithm, which is developed for the strap-down inertial navigation systems of satellite launch vehicles, is considered. For fast and accurate alignment, a simple closed-loop estimation algorithm using a proportional-integral controller is introduced. Through computer simulation for the sway condition in the launch pad, it is shown that a simple filter structure can guarantee fast computational speed that is adequate for real-time implementation as well as the required alignment accuracy and robustness. In addition, its implementation results are presented for the Naro-1 flight test.
