Laminate veneer는 전부도재 크라운 보다 전.구치 포함 적용범위는 매우 넓다. 또한 치관 형성시 요구되는 시간이 단축되며 침습 또한 적은 장점이 있다. 그러므로 치은에도 우수한 심미성과 기능개선을 가능하게한다. 환자의 고통과 치질손실의 부담도 훨씬 줄일 수 있으므로 앞으로도 잔존 자연치아의 심미성과 기능개선의 중요한 역할을 담당할 것이라 생각한다. Recently, according to the concept of minimal invasive, there have been many opportunities for restoration treatment with porcelain laminate veneers that are less invasive and can ideally improve esthetics. Patients also visit the laminate well, and patients also want to reduce the amount of teeth cut, so the choice of the entire trimming crown is decreasing. Therefore, various techniques of laminate are required. Most dental clinicians seem to have negative images of laminates such as risk of fracture, margin pigmentation and dropout. However, this situation is due to incorrect adhesion manipulation and lack of inspection of the occlusal relationship, and there is no problem with the Porcelain Laminate Veneer itself. The purpose and scope of adaptation leading to the success of porcelain laminate veneer will be introduced.

In the Republic of Korea, the importance of maritime safety has been increasing since the Sewol ferry accident(2014). In particular, various training and hands-on education are being conducted at schools and maritime-related organizations to promote the awareness of the maritime safety to the public, not limited to maritime-related workers. However, the curriculum for instructors for systematic training is mentioned only in the relevant research, and the study of the specific curriculum for them is not proceeding. Therefore, a survey of the domestic maritime safety promotion program and the similar overseas programs conducted for the public was conducted, and the basic training (IMO Model Course) of the STCW Convention and the basic safety training of the Seafarers’ Law were compared. Through this, a curriculum for the instructor-building training course that can be combined with theory and practice was developed and systematized through the four-year curriculum from 2014. Furthermore, surveys were conducted before and after the training and its effectiveness was verified. As a result of the survey, it was confirmed that their level of knowledge about marine safety increased. Through this study, it is expected that the process of developing and systemizing marine safety programs can be used as basic data on how to activate marine safety programs.

워터젯 로봇의 가공 전용 치구 제작 공정 개선 및 평가에 관한 연구

김선규(Sun-Kyu Kim) 한국산업기술융합학회(구. 산업기술교육훈련학회) 2024 산업기술연구논문지 (JITR) Vol.29 No.1

워터젯 로봇의 적용은 다양한 소재의 절단, 세척, 드릴링 등 많은 분야에 적용되고 있으며, 최근 자동차 내장재 자동화 공정 라인으로 확대되고 있다. 이에 따라 워터젯 로봇 가공 기술이 발전함에 따라 복잡한 형상의 자동차 내장재 가공을 위해서는 제품 형상을 지지해주는 전용 치구가 요구된다. 기존 워터젯 가공의 전용 치구는 제조 단가를 낮추기 위해 유리 섬유를 적용한 Wet Lay-up 공정으로 제작되고 있었으나, 최근 자동화 라인에 적용되는 워터젯 치구는 사용 시간이 증가함에 따른 변형으로 인하여 형상 가공 오차 발생으로 불량률이 증가하고 있다. 따라서 본연구에서는 워터젯 전용 치구의 품질 개선을 위해 탄소 섬유 적용 및 VARTM 진공배깅 공정을 적용하여 기존 Wet Lay-up 방식의 전용 복합재 치구 대비 형상 변형률 감소 및 전용 치구 구조 강도 향상을 위하여 제작 공정 개선및 평가에 대한 연구를 진행하였다. Water-jet robots find application across various domains, including cutting, cleaning, and drilling diverse materials. Recently, they have been integrated into automated process lines for manufacturing automobile interior components. Consequently, with the advancement of water-jet robot processing technology, a dedicated fixture is required to support the product shape for processing complex-shaped automobile interiors. The existing water-jet processing fixtures were produced through a wet lay-up process using glass fiber to reduce manufacturing costs; however, recently, water-jet fixtures employed in automated lines have experienced deformation over prolonged usage, resulting in shape-processing errors and an increased the defect rate. Therefore, this study explores the use of carbon fiber and the VARTM vacuum bagging process to enhance the quality of water-jet dedicated fixtures, refine the manufacturing process, alleviate shape strain, and bolster the structural integrity of the fixtures compared to the conventional wet lay-up method typically employed for composite fixtures. A study was conducted on.

This study concentrates the effect of hybridisation on the collapse mode and energy absorption for composite cylinders. The static collapse behavior of laminated(Al/CFRP/GFRP) circular-cylindrical composite shell under quasi-static axial compressive load has been investigated experimentally. Eight different hybrids of laminated(Al/CFRP/GFRP) circular-cylindrical composite shell were fabricated by autoclave. Eight types of composites were tested, namely, Al/carbon fiber/epoxy, Al/glass fiber/epoxy, Al/carbon-carbon-glass/epoxy, Al/carbon-glass-carbon/epoxy, Al/carbon-glass-glass/epoxy, Al/glass-glass-carbon/epoxy, Al/glass-carbon-glass/epoxy and Al/glass-carbon-carbon/epoxy. Collpase modes were highly dominated by the effect of hybridisation. The results also showed that the hybrid member with material sequence of Al-glass-carbon-carbon/epoxy exhibited good energy absorption capability.

A method for fabricating a skin-stringer Co-cure structure is investigated in which the existing skin and stringer assembly structure of an aircraft fuselage is formed by applying the composite air bladder bagging process with autoclave equipment. Most aircraft fuselage composite parts are in Korea using pre-impregnated material-based autoclave processes, and the skins and stringers are separately molded into parts and assembled by applying adhesives and fasteners to develop composite parts. In this case, the assembly labor-hours and manufacturing cost both increase because a separate assembly tool needs to be manufactured. To compensate for this, a method of forming a composite skin and stringer of an aircraft fuselage in a Co-cure structure by using an autoclave process was studied to produce a part specimen of the fuselage to ascertain the forming possibility and identify manufacturing problems.

대상으로서의 목소리

Thanks to Lacan"s Psychoanalysis, we can regard a voice as theoretical object. This essay examines the object small a , which Lacan determines as the bone which got stuck in the subject’s throat such as objectal remnant, through the conception as an objectal remnant, leftover, of the signifying operation, of the capitonnage. The status of voice in Lacan implies the criticism on phonocentrism defined by Derrida. Derrida brought in the voice/writing to deconstruct phonocentrism in specific point. However, Lacan suggests that it is the voice itself that damages the voice referred to as transparent self-presence in there. From this point, we may be faced with Hegelian identity as the coincidence of the opposites. ‘The voice is a voice’―If the former is transparent one of self-presence defined by Derrida, the latter is one as foreign body that undercuts self-presence from within. Therefore, Derrida"s binarity(voice/writing)is already secondary idea. Lacan said that "There is no subject prior to the voice." Now, We can understand the difference between Derrida"s Differance and Lacan"s antagonism as Real. For Derrida, Differance indicates an impossible continuous and constitutive diffrance in self-identity. But Lacan"s antagonism as Real is inherent impossibility. This implies the difference in their deconstructive strategy. In chapter 4 and 5, this essay shows the difference between remainder and excess as two types of leftover. To explain this, Zizek adopts Lacan’s ‘formulas of sexuation’. Leftover is based on the universal/exception rule. The status of voice lies in transgression against an established symbolic order. But the transgression don"t subvert it like a revolutionary element but rather make it operated smoothly. The voice as leftover is a singular agent of radical universality. It is the element which has no proper place in the official universality grounded in exception. According to Lacanian formula of sexuation, it follows the feminine not-all . It is very important in that we should pay attention to the exception rather than formal power of symbolic order. Not all of the subject is within the figure of legal subjection. There is no direct path to ‘not all’ in the law of exception. The path to ‘not all’ does just open up through a traversal of the fantasy of exception sustaining the force of the figure of legal subjection. ‘Not all" in feminine formulas of sexuation is what you get with the traversal of the fantasy. This is a mere gap among the viewpoints.

This paper aims to survey Hans-Georg Gadamer`s ontology of artworks show limits of modern scientific methodology. The main argument is “the experience of art is the very experience that uncovers the essence of the experience of truth.” And this is principal theme in Truth and Method(Wahrheit und Methode, 1960) by Gadamer. Gadamer criticize that modern aesthetics considered artworks as thingly object. According to Gadamer, Artworks reveal non-methodological truth that be connected with our living world. To understand artworks is not scientific cognition that analyze the ingredients of object but vibrant event(Geschehen) that couldn`t determined permanent meaning. To explain this character of artwork, Gadamer introduced concept the ``play(Spiel)``, as non-thingly object, only exist in playing. Frankly speaking, the play is way of being of artworks. The play is restricted by effective-history, as a result could not only fix the temorality, but also fix the meaning. The important thing is engagement(Dabeiseins) with the play. Player who be engaging play of artworks could not be separated from play of artworks. So the structure of artworks could overcome cognitive problems that occurred in separating strictly both subjet and object in cognition. Through solving the problem of dualism, Gadamer could explain unique being of artworks that can`t be restricted in methodolgy. In playing Artworks has the character of a work, of an ergon and not only energia, which Gadamer called the transformation into structure(Gebilde). Transformation into structure is not simply transposition into another world. The structure means unique being of artworks that could not be estimated by other criteria. So artworks mean an closed world which measured itself by nothing outside it.
