This study examined on the most noticeable game industry in a digital era, and on the definition and feature of post-digital generation enjoying it, along with the relations with the game. Especially, this paper examined correlations between game characters' fashion and pop singers' fashion targeting post-digital generation enjoying games. As the result of this study, on-line game's popularity affected popular culture and game business and popular stars have close interrelation. In addition, through variosus objective surveys, the game characters' fashion was classified into five images before being analyzed; fighter's image, retro image, surreal image, sensual image, and unisexual image. The game characters' fashion wasn't only analyzed also studied correlation between on-line game character's fashion and pop singers' fashion by five images. Consequently in case of game characters' fashion, it influenced on pop singers' fashion targeting teens and twenties enjoying games, which meant fashion connections between game characters and pop singers.

This study explores the characteristics and effects of a pop-up store based on how the store attributions of a pop-up store influence brand attitude and brand patronage intention. The questionnaire consisted of 3 instruments: store attributes, brand attitude, and brand revisiting intention. Data were analyzed by factor analysis, frequency analysis, reliability analysis, and multiple regressions, using SPSS 18.0. We surveyed 123 males and females, who had an experience of a pop-up store, and interviewed five experts who work in the fashion related area. The results of this study were as follows. First, it was shown that VMD has positive impacts on brand patronage intention, but with no significant relationship to brand attitude. Second, a brand culture's experience of a pop-up store has a strong influence on brand attitude and brand patronage intention. Third, products in the store are the most important factors that influence brand attitude. The findings indicate that the promotion of diverse attributes of apop-up store is critical to make customers perceive brand attitude and brand patronage intention that are expected to be used to establish advanced marketing strategies.

Binary interactions may have significant impact on Pop III stellar evolution. Pop III single star evolution indicates that for primary masses less than $20M_{\odot}$, no significant binary mass transfer would occur before core helium exhaustion. We perform binary system evolution for various primary masses ($20M_{\odot}$ < $M_1$ < $60M_{\odot}$) and initial periods under same mass ratio $M_2/M_1=0.9$, and follow the evolution and mass transfer of the primary star. If binary mass transfer occurs during post main sequence, the primary star does not evolve into naked helium star and still contain significant hydrogen in the envelope. During the post mass transfer phase, the primary star evolves redward, and does not become sufficiently hot to enhance the number of ionizing photons, compared to the case of single star evolution for a given initial mass. This result implies that primary stars of massive Pop III binary systems would have little contribution to the reionization in the early universe. Given the large hydrogen content ($0.326-1.793M_{\odot}$), the primary stars that underwent stable mass transfers would explode as a Type IIb supernova, and it would be difficult for Pop III binary stars to produce Type Ib/c supernovae that look similar to those found in the local universe.

K/DA is a K-pop virtual idol based on the game character. This study analyzed the creation process, characteristics and existential meaning of virtual idols from the perspective of Pataphysics. K/DA is a character with both characteristics of game character and K-pop girl group. Also, virtual character and real idol share the body through motion capture and augmented reality(AR). As a result, K/DA crosses virtual and reality, and at the same time becomes a pataphysical subject that does not belong to either virtual or reality. K/DA is suggested a third zone where digital subjects will be located in the future.

Digilog book using augmented reality is a form that augmented reality is implemented by illuminating the camera embedded in the mobile image on the page registered as an image marker after downloading the application, which shows a fragmentary limitation in the content implementation method. Therefore, in this study, we proposed a pop-up multi-tracking method that enables two-way interaction in a digit log book using augmented reality technology. Through this, we commissioned an authorized agency to test the technical differentiation of augmented reality content for two prototypes of existing book-type Digilog Book and Pop-up-type Digilog Book. A test report was issued. The pop-up type digit log book suggested in this study enables the user to implement the interactive contents according to the user's action (movement). This can induce the interaction between the virtual image and the printed picture book and give the learner an interest and immersion, so that it is possible to express the interaction of the digital log book.

This paper suggests a specific model that could efficiently improve the interaction and the interface between MES(Manufacturing Execution System) server and POP(Point Of Production) Terminal through RFID(Radio Frequency Identification) system in Automative Module Assembly Line. The proposed model shows that the new method by RFID can more efficiently perform to receive work order informations and transmit work performances, compared with the current approach by proximity sensor. As a result of the certain test among the MES server, RFID system, PLC(Programmable Logic controller) and POP terminal, it is noted in case of the automatic control by RFID that the effects of proposed model are as follows; (a) While the processing time per truck for carrying by the current method was 10 minutes, the processing time by the new method was 1 minutes. (b) While the error rate by the current method was 20 %, the error rate by the new method was 1 %.

The purpose of this study was to investigate biomechanical factors on key motions in K-Pop dance(BoA's No.1). A professional choreographer who was BoA's K-Pop No. 1 dance participated in this study. ROMs(range of motion) of shoulder and elbow joints in AP direction were greater than other joints. Those of trunk and pelvis in ML direction were the greatest of other directions. The velocity of CoG in SI direction was greater than other directions, and also max angular velocities of shoulder, elbow, knee, and hip joints in AP direction were the greatest of all directions. But ROM and angular velocity of ankle joint were very small. Max rotational powers of shoulder and knee joints were larger than other joints.

Contemporary people can form a broad social sympathy on cultural products based on the present Korean image. K-pop is good material to use to share korean culture, and fans who are enthusiastic here are increasingly demanding cultural products. The visual materials of Bangtan Boys are collected from their album covers, and a concept book, and divided into specific and symbolic images. Based on this motif, three specific images: 'bulletproof vest', 'army house + superhero extract image', and 'Wings symbol', six designs were proposed. In addition, six motifs from the music videos for recent popular songs, 'Spring Day', 'Blood, Sweat and Tears' and 'Burning Up' were selected as symbolic images. Each selected image is divided into a normal line and a special line. The former is a relatively small, stable, and popular style, and the latter is a large, original, and bold style. By drawing and transforming extracted images and motifs using Adobe Illustrator CS6 and Adobe Photoshop CS6 program, a full-width umbrella design was developed. The messages that the Bangtan Boys wants to convey through their music are put into cultural products that contemporaries can sympathize with. By developing umbrellas, a variety of items and design goods can become desirable points of consumption as high-value products by domestic and foreign fandom. If designs that incorporate various elements of future K-pop contents as well as other Korean Wave contents are developed, it will be possible to develop original design products that will form global understanding.
