Pop-in deformation phenomena in aluminum was studied. Whether a pop-in occurs or not depended on the surface polishing method. Pop-in did not occur in aluminum which was polished mechanically, while it occurred in aluminum which was polished electrically. When pop-in occurred, elastic deformation preceded. Pop-in mechanism based on dislocation activity was suggested. Suggested mechanism was consistent with the result of microstructure analysis by Focused Ion Beam polisher (FIB) and Transmission Electron Microscopy (TEM).

This paper describes a wireless point of production(POP) system using Bluetooth that is used as a tool of a new wireless interface. We developed the wireless POP system that is composed of POP terminal and control software. The POP terminal wirelessly collects the shop floor information in real-time. And the control software helps to make appropriate decisions based on the collected information by the POP terminal. The software is developed by using Visual C＋＋ programming language. A case study is implemented to show the performance of the developed system.

가장 큰 예술 대중매체인 k-pop은 다양한 안무 퍼포먼스를 필두로 대중에게 새로운 경험과 색다른 소통을 하게 도와줄 책임이 있다. 현대무용과의 결합을 통해 k-pop은 예술적 형태의 'Art 퍼포먼스'라고 불리 우며, 무용은 k-pop의 대중적 성질을 가지고 거리의 장벽이 낮아졌다. 이것을 변화되는 안무 디자인의 새로운 '문화 트렌드', '대중화 코드'로 인식하여야한다.

The global success of PSY's Gangnam Style was mediated through combination of YouTube and SNS. PSY's success led into some communication scholars' consideration of new international circulation of Korean pop culture (Korean Trend 2.0). In terms of global circulation of pop culture, it is noticeable how users appropriate YouTube channel beyond mere watching music videos and mere international circulation of Korean pop culture. The mode of fan's activity and appropriation contributes to the expansion of the width and amplification of the volume of Korean popular culture as well. The circulation of pop culture was considered in the level of exchange of tangible commodities such as CD, DVD, and so on until the adoption of digital media and Internet. YouTube has brought new mode in which the international circulation of pop culture is mediated without exchange of tangible commodities but was amplified with the diffusion of network. This study grasps how the mode of users' appropriation contributes to international circulation of pop culture through case studies of some K-pop music videos and international K-pop fans' tribute activities. In terms of theoretical perspective, fandom studies will be examined. In terms of research method, the researcher adopts netnography, a participatory observation on network, to find the feature of fandom and its contribution to the international circulation of pop cultures.

The release of steroids such as progesterone, testosterone, estrone and estradiol were investigated in two types of block copolymer matrices, which were AB type block copolymer composed of poly(γ-benzyl-L-glutamate)[PBLG] as the A segment and polyoxypropylene[POP] as the B segment and ABA type triblock copolymer composed of the A segment and poly(propylene glycol)[PPG] as the B segment. The release rates of progesterone, estradiol and testosterone through PBLG-POP1 and PBLG-POP2 matrices and those of progesterone, estrone and testosterone through GPG1 of ABA type triblock copolymer were higher in an acidic solution than in a basic one. However, the release rate of estrone through PBLG-POP1 and PBLG-POP2 matrices and that of estradiol through GPG1 of ABA type triblock copolymer were higher in a basic and neutral solutions than in an acidic one. The order of release rate in three different matrices was GPG1 > PBLG-POP1 > PBLG-POP2. The results also showed that the molecular weight of steroids is inversely proportional to the rate of release.

According to spreading K-pop globally, the market size related to K-pop stars is increasingly growing at home and abroad. Recently, services and products having direct interaction with the star are emerging. This research aims to propose a new service using a smart, connected social robotic figure that can support interaction between fans and K-pop stars. For this study, we begin by exploring literature about K-pop culture. Also, we investigate cases that connect between fans and stars and then build the development directions for a new service. Based on these development directions, we extract feasible technology and its interaction elements through analysing the cases of social robots. Finally, we propose the social robotic figure service in this research. This service proposed in this study can create and enhance diverse bidirectional communication between fans and stars through employing a user-customized, smart, connected figure based on a IoT platform. This research contributes to approaches for sustainable advance of K-pop through applying IoT technology.

This study examined the expression characteristics in pop art works of Jean-Charles de Castelbajac. The study here aimed at possibility to find a design development in building up the unique art world of creativity based on popularity, artistry, and originality without confinement to the trend only. For the research method, review of literature and analysis about Castelbajac's works reflecting the pop art feature in the collections from 2000S/S to 2012F/W were performed. The results of research are as follows. The external expression form of Castelbajac's works based on pop art was grouped roughly into use of mass culture image, appropriation of pop art expression technique, and parody of art works. First, his work appeared as application of the mass culture image such as symbolic thing in the modern consumer society, object in an ordinary life, character of well-known animation, national flag and famous star. Second, such appropriated pop art techniques showed as pop color in strong primary color and silk screen, photomontage, collage, assemblage, graffiti, and lettering. Third, a variety of images featured earlier in art works were shown in parody. These works are valuable in that they are expressed aesthetically through regeneration of popular culture's various images in view of fashion, they are described in the non-traditional value with frolic resistance and deviation out of existing fashion norm, and they are given the dynamic creativity integrated with art and fashion.

The purpose of this study is to analyze the acceptance and interpretation of pop musician's image in the Korean youth subculture, Fan Costume play(Fancos). Fancos subculture took the most active attitude to accepts of the pop musician's image and therefore was assumed to have various and differential acceptance aspects. The ethnographic method was used in order to approach more closely from their point of view. The cultural activity of Fancos subculture was imitation and reappearance of pop musician's appearance. Actually Fancos is a kind of fan-culture which idolized Korean pop music star. The acceptance of musician's appearance in Fancos is found out in two aspects. One is passive acceptance aspects that inforces conformity of star fashion and follows servilely ideal body image which promoted by cultural industry. The other is unique acceptance aspects that Fancos members interpret the musician's image in their own way. Those members experience pleasure through their own meaning. And homology of their appearance makes a distinction between of themselves from other youth and intensifies their group identity. As above analyzed, Fancos subculture has differential acceptance of pop music star's image comparing to other youth and even their stylistic appearance reflects not only their fandom but also their own meaning. Consequently, pop musician's image as a popular cultural text is accepted not equal to all populace but dissimilar along with contexts and trails of the acceptance group.
