Purpose: The postoperative maxillary cyst (POMC) develops as a delayed complication of many years after surgical intervention in maxillary sinus. We report a case of postoperative maxillary cyst invaded into the orbit causing displacement of the globe, which was successfully treated with drainage under nasal endoscopy. Subject and Method: A 38-year-old man visited the hospital complaining of palpable mass on his right lower eyelid area for -10days. He had had CaIdweII-Luc operation for maxillary sinusitis for 10 years ago. Examination revealed hard and painless palpable mass on his right lower eyelid area. Computed tomographic (CT) scan of head and orbits revealed a low density, cystic mass in the right maxillary sinus invaded into the orbit, displacing the globe superiorly. We found a bulging cystic mass supero-posterior to the middle turbinate, and we performed incision and drainage under nasal endoscopy. Result: At third postoperative day, successful treatment of cystic mass was confirmed by nasal endoscopy, with disappearing of palpable mass on right lower eyelid area. Conclusion: We suggest that nasal endoscopic surgery in treatment of postoperative maxillary cyst invaded; into the orbit maybe effective method.

애니메이션에 나타난 남성 중심적 시선의 전복 연구 : 조안나 퀸과 앨리슨 스노우덴의 작품을 중심으로

고민정,김재웅 영상예술학회 2010 영상예술연구 Vol.16 No.-

영국 애니메이션의 황금기라고 일컬어지는 1980년대 중반에서 1990년대 중반에 이르는 기간 동안 여성 감독들에게 우호적인 환경이 마련되었다. 조안나 퀸(Joanna Quinn)과 앨리슨 스노우덴(Alison Snowden)은 이 시기에 활동을 시작했는데, 세계적으로 명성이 높은 안시 국제 애니메이션 페스티벌에서 스노우덴의 <2급 우편>(Second Class Mail)이 1984년에, 퀸의 <걸즈 나잇 아웃>(Girls’ Night Out)이 1987년에 각각 수상했다. 이 두 작품은 남성 중심적 시선에 따른 여성 재현이라는 기존 관습을 전복하는데, 퀸과 스노우덴은 이후에도 90년대 중반까지 이와 비슷한 경향의 작품들을 제작했다. 존 버거와 로라 멀비의 지적처럼, 여성을 대상화하는 남성 중심적 시선은 가부장제와 자본주의 사회에서 구조화된 시각양식이며 이것은 회화, 사진, 주류영화 뿐 아니라 밥 고드프리(Bob Godfrey)와 텍스 에이버리(Tex Avery)와 같은 남성 감독의 애니메이션에서도 지속적으로 나타난다. 그러나 조안나 퀸과 앨리슨 스노우덴은 밥 고드프리와 텍스 에이버리의 섹스 코미디를 패러디하여 기존의 회화와 애니메이션에서 재생산되던 남성 주체와 여성 대상이라는 관습을 전복한다. 여성 캐릭터들은 더 이상 성적 대상으로 머무르지 않고 스스로 욕망하는 주체이자 욕망을 성취하기 위해 행동하는 존재로서 남성 캐릭터를 밀어내고 그의 행동을 그대로 재연한다. 반면 시선의 주체인 남성은 성적 대상으로 전락한다. 그러나 남녀의 역할 전도를 통한 남성 중심적 시선의 전복은 오히려 성적 이분법을 강화하기 때문에 진정한 의미에서 전복이라고 할 수 없다. 퀸과 스노우덴의 시도는 남성적 시선에 반대되는 여성적 시선을 제시한다기보다는 이미 익숙하게 몸에 배어 있어서 당연시하게 되는 기존 관습의 존재 자체를 깨닫게 만드는 역할을 한다. 애니메이션은 다른 ‘진지한’ 예술들과 달리 관습을 깨고 변형시키는데서 새로운 유머를 생산할 수 있기 때문에, 지배적 재현을 해체하는 것은 일종의 전략적 실천으로서 유머를 창조하는 수단으로 작용할 수 있었다. There was a supportive environment for female filmmakers from the mid- 1980s to the mid-1990s, the so-called “golden age of animated film in the U.K.” In those days, Joanna Quinn and Alison Snowden began to create their own works. Both Snowden’s Second-Class Mail (1984) and Quinn’s Girls’ Night Out (1987) won the best-animated-film award and three other awards at the Annecy International Animated-Film Festival. In their respective works, they subverted the traditional representation of women as merely objects of the male sexual desire. Quinn and Snowden came up with a series of animations with the same subject until the mid-1990s. According to John Berger and Laura Mulvey, the male gaze, which is brought about by patriarchy and capitalism, is reproduced in photos and in the mainstream and animated films of male filmmakers. The works of Quinn and Snowden, however, which spoof the sex comedies of Bob Godfrey and Tex Avery, subvert the tradition of the male subject and the female object. In their works, the female characters are not depicted as objects of the male sexual desire. They reenact the male character’s role to make desire a subject, and a male who becomes the target of a gaze even just once may be degraded into an object of sexual desire. There is no true subversion, however, of the changing roles between men and women in the works of the two female filmmakers because their works actually further reinforce the sexual dichotomy. Quinn and Snowden’s attempts do not make the female gaze contradictory to the male gaze but make people realize the traditional representation of women. Contrary to serious art, it is a strategic practice to break dominant representations and to create new humor in animated films.

비전기식뇌관의 트렁크라인 시차가 발파진동에 미치는 영향

강추원,고진석,김재웅 朝鮮大學校 建設技術硏究所 2000 建設技術硏究 Vol.20 No.1

In this study, blasting condition uniformed, and vibration value changed by the trunk line and measuring distance was measured. Four patterns of delay time of surface detonator and trunk line which are used at open fit blasting UB-25 and surface detonator of UB-17, trunk line UB-17 and surface detonator of UB-42, and trunk line of UB-25 and surface detonator of UB-42 are used in pattern 1, 2, 3, and 4 respectively, In result, the overlap time in pattern 1, 3 are 10 times respectively. Because of that reason, the value of vibration velocity in pattern 3 is smaller than in pattern 1. As the time difference of Trunk line, a method of decreasing the surface vibration is to design the number of overlap minimized a t interval time.

Fabrication of Ultra Fine MgO Particles Added BSCCO 2223 Tapes with Different Precursor Phase Constituent

Ko, Jae-Woong,Yoo, Jai-Moo,Kim, Hai-Doo,Chung, Hyung-Sik The Korean Superconductivity Society 1999 Progress in superconductivity Vol.1 No.1

Ultra fine MgO particles added BSCCO tapes were fabricated by tape casting using Doctor Blade Method and enclosed by silver foil for different starting compositions (that is, 2223 major, 2212 major). In order to obtain optimum microstructure, thermomechanical treatment was done. Microstructure and phase were analyzed by XRD, SEM and DTA. The critical current density was measured under magnetic field at 77K. The tapes fabricated from the precursor powder with BSCCO-2223 phase (>90%) result in a microstructure with a larger grain size and higher transport critical current density value under magnetic field at given thermomechanical treatment conditions.

Coexisting Ferroelectric and Paraelectric Phases in Electron Beam Irradiated P(VDF-TrFE) Films

Jae Woong Kim,Tae Kwon Lee,Jong Hoon Jung,Sunhyeop Shin,Byoung Wan Lee,Jae-Hyeon Ko 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.11

We report on structural, electrical, and Raman investigations of phase changes induced in P(VDFTrFE) films by electron beam irradiation. With increasing electron beam dose, the ferroelectric β-phase is weakened because of reductions in the coercive field, remnant polarization, and Curie temperature. Finally, highly dosed (9.38 × 1016 cm −2) P(VDF-TrFE) shows a paraelectric α-phase. A Vogel-Folcher type relaxor behavior becomes strong with the decreasing freezing temperature and the increasing activation energy. From the Raman scattering measurement, we observed that both the α- and the β-phases coexist irrespective of the electron beam irradiation and that the temperature dependences of the α- and β-phases are quite different. The ratio of the intensity of the α-phase to that of the β-phase sharply increases at a certain temperature, at which polar nanoregions may disappear.

The $MgB_2$ tapes with several metal powder addition were fabricated by PIT method with or without heat treatment. The $J_c$ value of $5.600A/cm^2$ and $16.000A/cm^2$ at 4.2 K and 5 T were obtained for the $MgB_2$ tape and 10 vol % of Cu added $MgB_2$ tape without heat treatment respectively. The $J_c$ value of $8.000A/cm^2$ and $35,000A/cm^2$ at 4.2 K and 5 T were obtained for the $MgB_2$ tape and 10 vol. % of Al added $MgB_2$ tape with heat treatment, respectively. The $J_c-B$ curve shows enhancement in $J_c$ under magnetic field. which suggests enhancement in workability and grain connectivity with several metal powder addition.
