In this paper, a method to control the noise and vibration of a standard gear transmitting mechanical power in the transmission insides, to things regarding a way to inspect the gear which was processed minutely. In an algorithm used to accurately measure a work gear, the measurements of the master gear are considered as the basis. The existing method considers one rotation of the standard gear and monitor gear, and that carried out mastering work in frequency ways. In this study, an algorithm to measure standard gear and monitor gear is proposed along with methods to calculate an error of the monitor gear and to significantly increase the precision of gear measurement. Further, the algorithm is fast and is expected to be capable of accurately measuring for mastering processing.

This paper presents a study on the helical gear inspection system for application to vehicle transmission gear manufacturing lines. The special gear profile inspection system is not suitable for manufacturing lines due to the measuring time. The master gear method, which was used in this study and compared with the machined gear in the line, is more efficient and economical. In this paper, three helical gear inspection parameters were of concern: nick, run-out, and PCD (pitch circle diameter) error. To evaluate its influence on the accuracy, the gear measuring system was also studied. This system can be useful in practical vehicle transmission gear manufacturing lines, where imported equipment is currently being used.

정보화가 발달할수록 데이터량은 증가한다. 21세기 정보화 시대가 말그대로 정보의 홍수속에 살게 될 것이다. 지금은 영상미디어 시대이다. 초고속인터넷시대는 향후 처리해야 할 정보가 단순 텍스트 데이터가 아니라 정보의 관리에 어려움을 가져왔다. 또한 인터넷이란 새로운 실시간 데이터 관리가 필요한 상황에서 고객의 어려움도 커져가고 있다. SAN(Storage Area Network)과 NAS(Network Attached Storage)는 가상화스토리지 전문기업 뿐만 아니라 이종 업체에서의 제안이다. 즉 NAS를 정의하는 방향도 다르다. 우선 서버 어플라이언스로 보는 업체로는 컴팩, IBM의 x시리즈, 마이크로테스트, 액시스 등이 있으며, IBM, 씬, EMC, 네트워크 어플리이언스, 히타치데이터시스템 등 전통적인 가상화스토리지 업체는 이를 가상화스토리지 네트워크의 한 아키텍처로 보고 있다. 이외에 맥스터, 퀸텀 등의 HDD업체들은 이를 네트워크에 연결할 수 있는 하드디스크로 보고 있다. 또한 네트워크 장비 업체인 3Com, 넷기어 등의 NAS제품을 보이는데 국내업체는 전무한 편이다. 예전에 우리가 포기한 고부가가 가치제품인 서버 스토리지 분야를 놓치면, 결코 국민소득 $2{\sim}3$만불 타령을 해야 아무런 소용도 없고 선진국에 기술 종속만 될 뿐이다. 그러므로 우리가 IT강국이라고 하는 데는 반성을 하여야 한다.

This paper proposes a new direction for Comparative Literature which has been deeply Eurocentric and even colonial ever since its birth. 'Comparison' in Comparative Literature has been in fact the ideological mechanism for containing, classifying, and eventually controlling all differences in the world. Literature has naturally served as a national institution of the West at epistemological and discursive level with hidden adjective "comparative". To re-conceptualize the discipline and practice of "Comparative Literature", we need to revolutionize methodology itself based on Wai Chee Dimock's idea of "Weak Theory", Foucault's "disappearance of author", and Clifford Geertz's "thick description". "Thick description" as a methodology of comparative literature re-establishes the discipline as a field of "weak theory", defusing the centrality of linguistic identity and re-making it as a "long network" of loose and missed connections. "Thick description" poses the publicness of nation-state within "confusion of tongues", problematizes the legitimacy of modern knowledge, and puts (the western) nationalism in question. With this idea as a starting point, we can re-imagine Comparative Literature anew as a field of ceaseless discourse of longer, weaker, and thicker networks of interpretation and re-interpretation of differences.

Social media such as twitter has been popular by the diffusion of internet, and thanks to the radical improvement of computational ability of computers big data analysis became possible. This research is regarding about smart watch which is receiving attention as post-smartphone technology. Among various types of smart watch, this research focuses on the recently released Samsung Galaxy Gear S2. The main purpose of the research is to analyze customer's actual twitter data that was produced before and after the release of the smart watch to the market. Through the analysis, this research provides practical marketing strategy guideline, and also the analysis framework used in this research can be a research framework for other area and product researches.
