In this study, focusing on workers wholesale optical frame, analyze the distribution of the optical frame, we studied the improvement of distribution. Has a work in the distribution industry and education in the various age groups, size of the company was small-scale. For the inventory management of the optical frame, systematic management is not performed, expectations for a better distribution system also was not large. In order to ensure better sales, wholesale optical frame company role intermediate of the spectacle manufacturers optical frame consumer deemed it is necessary to ensure the activation of internet sales and joint sale.

본 논문에서는 렌즈의 흠집을 추출할 수 있는 퍼지 기법을 이용한 렌즈 흠집 검출 방법을 제안한다. 제안된 방법은 렌즈 영상을 그레이 영상으로 변환한 후, 캐니 마스크를 이용하여 렌즈의 경계선을 추출한다. 추출된 렌즈의 경계선에 대해 평균 이진화와 모폴로지를 이용하여 렌즈 경계선을 보정한다. 렌즈 경계선이 보정된 영상에서 Seed Fill 알고리즘을 적용하여 렌즈의 내부 영역만을 추출한다. 추출된 렌즈의 내부 영역에 해당하는 원 영상에서 소벨 마스크를 적용하여 렌즈 내부 영역의 에지를 추출한다. 렌즈 내부 영역에서 추출된 에지 객체들의 정보를 이용하여 흠집과 비흠집을 분류하는 퍼지 기법을 적용하여 흠집 영역을 추출한다. 본 논문에서 제안된 렌즈의 흠집 검출 방법의 성능을 평가하기 위해 CHEMI, MID, HL, HM 시력 보정용 렌즈를 대상으로 실험한 결과, 제안된 방법이 흠집을 효과적으로 검출하는 것을 확인하였다.

A smart material is used as spectacle frames and brassiere frames, and partly in medical supplies because of its shape memory effect. The smart composite can be used on the wing of an airplane instead of the existing aluminium to control crack propagation. In this study, the smart composite was fabricated by a hot press method. TiNi alloy as reinforcement and A16061 as matrix were used, respectively. The mechanical properties of the smart composite under thermal shock cycles were evaluated. In addition, Acoustic Emission techniques were also used to clarify the damage behavior of the smart composite under thermal shock cycles nondestructive.

This essay is an attempt to give a theoretical articulation of novelistic mimesis as the narrative form of modernity. With the passage to modernity, what assumes the locus of the symbolic authority is no longer God, Father, or tradition, but the cultural gaze or the ego-ideal. At the same time, this gaze paradoxically coalesces with the "spectacle of the world," on the side of the reified "other": the gaze is both the desexualized ego-ideal and its instantaneous transmogrification and resexualization in the opaque world of objects. The imaginary ego or the eye on the side of the subject of representation is held at abeyance in a state of perpetual fascination and desperation in relation to the gaze as the world of "others," which lies always at one remove from the purview of the imaginary ego. This understanding of the inadequation of the ego to the cultural gaze of the reified world provides a critical fulcrum upon which I base my theory of the modern narrative mimesis as the "perverse" field of spatial arrangement, in which the split of the subjectivity into the imaginary ego and the ego-ideal is suspended over the phantasmatic world of bodies and territories.

The objective of this study is to investigate proper cutting conditions of cellulose acetate(CA) for eyewear frames. Various cutting experiments with variation of spindle speeds and feed rates are conducted to evaluate the machinability of CA. The machinability of CA materials were discussed in terms of the cutting forces, surface roughnesses and chip formations. The cutting conditions of high spindle speeds and the feed per tooth of less than 0.05mm are recommended considering the surface roughnesses and chip formations. Also, the correlation between the surface roughness and the chip formation is investigated. These results are able to be applied to design the high-speed machine tool of CA frame.

Spectacle diopter of age related changes during 5 years examined 360 eyes(male 79, women 81) who visited optical shop every year. Increasing refractive error of Myopia obviously appeared in young generation which term was elementary school, and then middle and high school. In this study, we concluded that term of correction spectacles should be 4 months in elementary school, 6 months in middle school, and every year in high school.

The Great Wall is an element in University which stand outs as a landmark. The Great Wall is located in front of the grand staircases of the gymnasium in the main gate area. Falling water and Lights shows a spectacle panorama in various point of view. Water falls down the top of the grand staircases and the front walls. And the red, blue and green lights brighten the falling water in the evenings. Also the relief of the palm tree and turtle symbolizes the University Identity. The wall is comprehends not only the day and the night but four seasons. The Water, Lights, and the Relief are coordinates well along with the new building in campus.

시각효과에 의한 스펙터클 요소는 영상콘텐츠에서 관객의 몰입감을 향상시키고, 작품성을 높인다. 특히 재난영화는 스펙터클 요소를 주된 연출 방법의 하나로 사용하여 관객의 기대와 감동을 키운다. 또한 영화제작기법과 함께 스펙터클 장면을 표현하기 위한 CGI기술의 발전이 영화 장르의 확장과 학문적 발전을 이끌어왔다. 그러나 스펙터클 요소가 내러티브에 영향을 끼친 연구는 지금까지 매우 미비하다. 본 논문은 스펙터클 요소가 재난영화의 내러티브에 끼치는 연구를 분석하기 위해 2019년에 개봉된 재난 영화 <유랑지구>를 분석하였다. 이를 위해 스펙터클과 내러티브의 개념과 특징을 이론적 배경으로 제시하고, <유랑지구>의 스펙터클 요소 분석과 극중의 내러티브와의 관계를 연구하였다. 본 연구를 통해 스펙터클 요소를 활용해 영화의 내러티브 강화에 도움이 되길 기대한다.

Purpose: Three-dimensional (3D) displays are very useful in many fields, but induce physical discomforts in some people. This study is to assess symptom type and severity of asthenopia with their habitual distance corrective spectacle (HDCS) and their binocular vision corrective spectacle lenses (BVCSL) in people who feel physical discomforts. Methods: 35 adult subjects (ages $32.2{\pm}4.4$ yrs) were pre-screened out of 98 individuals to have the highest symptom/asthenopia scores following 65 minutes of 3D television viewing with HDCS. These 35 individuals were then retested symptom/asthenopia scores during they watched 3D television for 65 minutes at a distance of 2.7 m with wearing BVCSL of horizontal, vertical or base down yoked prisms. A 4-point symptom-rating scale questionnaire (0=no symptom and 3=severe) was used to assess 11 symptoms (e.g., blur, diplopia, etc.) related to visual fatigue/visual discomfort. Distance and near lateral phoria were measured using Howell phoria card and vertical phoria were measured using Maddox rod. Symptoms induced by watching 3D TV were compared between wearing HDCS and BVCSL. Results: Asthenopia in watching 3D TV with wearing BVCS was significantly lower than wearing HDCS at 5, 25, 45, and 65 minutes (all p < 0.001, paired t-tests). In only refractive error power correction power group, all asthenopia was not significantly different between HDCS and BVCSL (all $p{\geq}0.05$, paired t-tests). In prism correction groups for binocular imbalance, symptoms of asthenopia, however, was significantly lower for when wearing BVCSL than when wearing HDCS (all p < 0.05). Conclusions: Correction of phoria/vergence-based binocular vision imbalance can reduce asthenopia during 3D television viewing. An individual with binocular vision imbalance need corrected/compensated glasses with appropriate prisms prior to prolonged viewing of 3D television displays to reduce asthenopia/visual fatigue.

Monovision is defined as correcting one eye for distance vision and the other eye for near vision. Single-vision contact lenses are used for each eye. The patient selectively suppresses one eye while using the other eye. This study was performed to measure binocular function and patient satisfaction with monovision induced by adding +3.00D to spectacle prescription for distance vision in nonpresbyopic students. This study comprised 144 nonpresbyopic students with monovision induced by adding +3.00D to spectacle prescription. Monovision was induced by undercorrecting the nondominant eye by adding 3.00 diopters for near vision and correcting the dominant eye with emmetropia for distance vision. For research of the binocular function on Monovision. This study was tested the obstacle course, water pouring test, catching and throwing, bead classification including the stereopsis test. These tests were comparative to the normal binocular state. As a results, the stereopsis have a significant reductions in Monovision. There was no significantly difference between monovision group and control group in monovision exercise (obstacle course, water pouring test, catching and throwing, and bead sorting) at near and distance. This study indicates that monovision is an effective and reasonable therapeutic modality for correcting presbyopia. By the application of above methods, this study could be used the student for the practical practice and understand on the Monovison.
