≪월인석보≫ 권 19의 진언 표기에 대하여: 종성 ‘ㅿ, ㅱ’을 중심으로
이찬식 언어과학회 2022 언어과학연구 Vol.- No.103
This paper explores the phonetic values, the principle of pronunciation, and the systematization of the final phonemes, codas ‘ㅿ, ㅱ’ appearing in the transcription for mantras of Wolinseokbo Vol. 19. ‘ㅱ, ㅸ, ㅿ, ㆆ’ appear as the final phonemes, codas in the transcription for mantras of Wolinseokbo Vol. 19, considering the phonological system of Chinese. This notation was identified as a method for notation of Chinese phonemes that are different from the Korean syllable structure or do not correspond to Korean. In this paper, the pronunciation of the codas ‘ㅿ, ㅱ’ and the principle of pronunciation were analyzed, and they corresponded to the Chinese [ɿ, ʅ] and [w] respectively. This was because each phoneme has the same place of articulation features. This analysis is expected to contribute to the establishment of the principle and system of the transcription for the final phonemes, codas in the foreign language notation of Hunminjeongeum. .
RF 스퍼터링법에 의한 Al-Sn계 코팅베어링의 제작과 특성 평가
이찬식,이명훈 한국마린엔지니어링학회 2000 한국마린엔지니어링학회지 Vol.24 No.6
The development of high performance materials is very important subject in order to enhance the properties of bearings whose role is to transfer energy harmoniously by reducing the problem of friction and wear down, etc. between the interacting solid surfaces in relative motion under high loads in comply with mechanical operating mechanism of engines. In this study, several (100-x)Al-xSn coating films (where x=85, 75, 65 atomic % at Al) on substrates which are abt. 2mm thickenss of Kelmet layer sintered back steel were prepared by using RF sputtering system. These coating films were observed the morphology by SEM(Scanning Electron Microscope) and investigated the crystal structure by XRD(X-ray Diffractor) for their properties. And friction coefficient of these films was measured by ball-on-disc tester for their tribological properties. From the experimental results, it was shown that high performance properties of bearing can be improved greatly by controlling the composition and morphology of material surface with effective use of the plasma-assisted sputtering process.
