The rise of K-Pop in the latecomer environment is unusual. There is little research on K-Pop from the catch-up perspective though it would yield some insight into a strategic direction of creative industries in the latecomer environment. Thus, this study aims to compare the firm capability, market development, and product strategy of K-Pop firms with ones of manufacturing firms during the catch-up period. It reveals first that K-Pop firms developed project execution capability to carry out discrete projects effectively by adopting in-house (vertical) system in music production and increasing the size of firms. Second, they pursued global market and utilized the window of opportunities based on a proven music genre. Third, K-Pop firms pursued the incremental innovation in the product development. Since these characteristics have many similarities with the catch-up strategy in the manufacturing sector, Korean catch-up experience could provide valuable insight into the development of creative industries in Korea.

본 논문에서는 자동화 사격장 Pop-Up시스템의 안정성 및 성능 향상을 위해 예측제어기를 설계하여 시간지연에 따른 문제를 보상하였다. 확률 모델에 기반한 예측제어기는 지연된 이전의 값들로부터 선형예측 기법과 확률함수를 이용하여 실제의 값을 추정하며, 이를 제어기에 적용하여 시간지연에 따른 문제점을 최소화하였다. 제안된 알고리즘의 타당성을 검정하기 위해 사격용 Pop-Up시스템에 본 알고리즘을 실현하였으며, 상이한 시간지연과 이득 변화에 따른 제어기의 성능을 관측하였다. 실험결과 제안된 예측제어기는 시간지연에 대해 PID 제어기보다 빠른 수렴 특성을 보이며, 제어기의 안정범위 내에서 허용할 수 있는 최대 시간지연 값도 증가시킬 수 있었다. 따라서 사격용 타겟의 Pop & Up동작이 제어시간 이내에 원활하게 작동되어 연속 사격의 실시간 제어를 효율적으로 수행하였다.

The ultimate purpose of the research is to solve the problem that fashion inspired by les Nouveau Pop Artic criticism and satirical factors is interpreted as concept of American Pop Art style, even though there is distinct difference between les Nouveau Pop Art style and American Pop Art style. We think that the reason causing the problem is that les Nouveau Pop Art is not familiar to the general public, even though it is getting attentions as trends treated by les Nouveau Pop Artists. Above all there is insufficient study to establish a theoretical system and a concrete concept on les Nouveau Pop Art. Therefore, this study is to set up the theoretical concept on les Nouveau Pop Art based on comparisons and analysis of the characteristics of works expressed les Nouveau Pop artists, and to draw the concept of les Nouveau Pop image fashion. The result of this study indicate that les Nouveau Pop Art Image Fashion is defined as "fashion design borrowing the concept and image from les Nouveau Pop Art and blending and consisting of the themes, characteristics and techniques from les Nouveau Pop Art.

In this paper, we propose an architecture of the DNC system for Shop Floor Control/Point of Production(SFC/POP). The DNC system to be presented this paper retrieves line-up sheets which include the drawing information, making a index database for line-up sheets, NC programs and tool adjustment data. And it is interface with a raw material, jig and tool information. Also, the DNC system transmits operation information to real workers rapidly, and supports realtime monitoring by collecting the state information of machines directly. In the analysis and design phases, this paper models realtime events using the state transition diagrams. In the implementation phase, we use the ORACLE DBMS(Database Management System) as the DBMS and Developer 2000 and Microsoft Visual C++ 5.0 as the programming tools.

A four-link mechanism consisting of torsion bars is used for opening the trunk lid in most midsize sedans. When the weight of the lid is in equilibrium with the spring force exerted by torsion bars, the lid stops opening at a pop-up height. However, the actual pop-up height has large deviations from the specified height even with the same parts in the same car model, which leads to quality issues. Automotive manufacturers have experienced this deviation problem despite much effort to resolve it. In this research, we developed a multi-body dynamics model for the analysis of pop-up deviation of a trunk lid with torsion bars, which can simulate the actual pop-up motion of the trunk lid by considering kinematic constraints of the motion and friction forces in joints. We could also determine the most important factor that governs the pop-up height by sensitivity analysis of all parts. The developed system can be used for the analysis of other trunk lid systems to control the tolerance of parts.

The hybrid phenomenon of pronunciation of K-Pop lyrics, which is the diction fusion phenomenon of lyrics, is not a strategic measure for an overseas expansion but a natural formation in the course of history of K-Pop. With the debut of Seo Tai-ji and Boys in 1992, the course of K-Pop changed and settled from ballad to dance music. After three years, the success of a hip hop dance music, 'Come Back Home', opened up a door to Korean Americans who ascertained the potential competitiveness of a hip hop music in K-Pop market. And the writer insists that such advance of Korean Americans into K-Pop market is the origin of the bilingual usage and diction fusion phenomenon of K-Pop lyrics. Therefore, this research will look into the pronunciation system of Korean and English in order to understand the bilingual pronunciation system shown in the lyrics sung by Korean American hip hop singers in the 1990s. Moreover, through Korean pronunciation system, this analysis will discover the main cause of continual acceptance and application of Korean American's broken Korean in the diction of lyrics. Last but not least, this exploration will show the correlation of English pronunciation method of Korean lyrics appeared in K-Pop and the diction of Korean lyrics used by Korean American hip hop singers in late 90s. This research will identify the primary cause of the diction fusion phenomenon in the course of history of K-Pop.

This thesis urges the change of the education system of popular music for globalization of K-POP in a longer point of view Korean popular music has developed not only musically but also sound quality itself. Moreover it became popular in a global scale in the name of K-POP. However, it is still limited to idol music, and numerous issues related to the lack of musical talent are emerging Even though the routine of birth and death of several idol groups and singers are still repeated. Recently, the skills of artists enhanced due to audition TV shows but still it's not enough. Under this situation, it is not appropriate to rely on audition TV shows and Entertainment Management companies for picking up talented artists. Therefore, like Classic or Traditional music, schools concentrated for popular music must be founded. If this become enabled, young students going to entertainment companies or to unqualified but expensive private institutes will disappear. Moreover, it can prevent students from lacking behind in their academic activity. In addition, a reformation should be done education colleges for raising popular music educators

An important factor in eye-tracking PC interface for general paralyzed patients is the implementation of the mouse interface, for manipulating the GUI. With a successfully implemented mouse interface, users can generate mouse events exactly at the point of their choosing. However, it is difficult to define this interaction in the eye-tracking interface. This problem has been defined as the Midas touch problem and has been a major focus of eye-tracking research. There have been many attempts to solve this problem using blink, voice input, etc. However, it was not suitable for general paralyzed patients because some of them cannot wink or speak. In this paper, we propose a mouth-pop-up, eye-tracking mouse interface that solves the Midas touch problem as well as becoming a suitable interface for general paralyzed patients using a common RGB camera. The interface presented in this paper implements a mouse interface that detects the opening and closing of the mouth to activate a pop-up menu that the user can select the mouse event. After implementation, a performance experiment was conducted. As a result, we found that the number of malfunctions and the time to perform tasks were reduced compared to the existing method.

Two-step or one-step bonding systems generally inhibit curing process of dual-cured core build-up resin composite for their adhesive acidity. In addition this dual-cured core build-up resin composite can be applied to dentin of pulp chamber and root at the time that complete the endodontic treatment. The purpose of this investigation was to determine the influence of sodium hypochlorite on rnicrotensile bond strength of dual-cured core build-up resin composite. Extracted human molars were horizontally sectioned with 1mm thickness using low speed diamond saw. After the sectioned specimens were divided into 8 groups, adhesive systems (Clearfil SE-Bond, Prime&Bond NT[2-step, 1-step], Adper Prompt L-Pop) were then applied with or without sodium hypochlorite pretreatment. The treated specimen was filled with dual-cured core build-up resin composite (Luxacore, DMG corp., German). Then light cured for 40 seconds and soaked in $37^{\circ}C$ water bath for 24 hours. After the treated specimen was grinded with 1mm width and measured rnicrotensile bond strength by testing machine. Additionally 8 teeth were prepared for SEM evaluation. The results were as follows. : NaOCl treated groups generally had lower rnicrotensile bond strength but did not show any difference statistically except Adper Prompt L-Pop. When the teeth were treated by NaOCl, though the difference of applied adhesive system, it had no statistically significant difference within the NaOCl treated groups except the relation of between ClearFil SE-Bond adhesive system and Adper Prompt L-Pop adhesive system. In the SEM evaluation, NaOCl treated groups presented relatively long resin tags and incomplete hybrid layer formation generally.
