The method to correct excessive exposure of maxillary gingiva while smiling are divided into two main classes of orthodontic and surgica1. The surgica1 methods are classified into maxil1ary osteotomy, maxillary alveolar osteotomy and mclosal resection technique. The surgical technique to correct of bone is more adequate in time of severe maxillary protrusion and anteri deep overbite exists. But the muosa1 resection technique is used when orthodonic treatment, maxillary osteotomy & maxillary alvedectomy techniques are inadequate, the complications of mucosal resection technique are pain, edema, hematoma, subcutaneous hemorhage, infection delayed healing of wound and stiffness of upper lip, but which almost disappear about a week after surgery. The mucosal resection technique, proposed by Kostianorsky and Rubinstein, is similar to vestibular extension technique, This mucosal resection technique is not only lighten the burden of the patient & surgeon, but alsoobtain the improved surgical resu1ts in short period Our department get the same good results.

「무정」과「만세전」의 철도 서사

In Mujung, Lee `s enlightenment about modernism is revealed, and the space of railroads plays a pivotal role in the narrative. In particular, the space of railroads in the colonized country is portrayed as strange, exotic scenery, voicing that Koreans should change their outward appearance initially like other foreigners. Also, it describes the majority of Koreans as people of old era and bemoans that they are totally ignorant of the order of new civilization including railroads. This narrative is, to some extent, derived from some fantasy the writer held. Because fantasy is parallel to admiration, the writer `s world view in literature is associated with desire of Romanticism, even when limiting to the narrative of railroads shown in Mujung In here, ‘railroads ` have a narrative character of dynamic motifs, functioning as tools to actively help characters ` behavior and their way of thinking as well as causing a change in situation. In Mansejun, Yom promotes awareness that railroads should not be considered just positively as Lee described. A large part of the story develops in the space of railroads, and especially, the part in which a dialogical relation between the main character ‘I’ and the opposite ‘Detective’ is described effectively shows that railroads are a symbolic sign which carries away suppression and discrimination. This narrative might be regarded that any hope is involved in it because it only depicts miserable realities which people confronted. For this reason, in here, the narrative of railroads is accomplished as static motifs which cannot bring any change in situation.

본 연구에서는 유기용매의 종류 및 함량, 계면활성제의 종류 및 함량, 보조계면활성제/계면활성제(cosurfactant/surfactant, A/S) 비율 등의 변수에 따라 배합된 마이크로에멀젼형의 준수게 세정제들의 물리적 특성과 플럭스에 대한 용해력을 측정하였다. 또한, 세정공정 중에 사용되는 헹굼액의 유수분리성을 측정하여 헹굼액의 재활용성을 평가하였다. 배합된 세정제들은 water-in-oil (W/O) 형태의 마이크로에멀젼을 형성하였으며, 30.2~32.5 dyne/cm의 낮은 표면장력과 낮은 점도 값을 보여 세정공정에서 침투력이 좋을 것으로 예상되었다. 플럭스에 대한 용해력은 계면활성제의 소수성이 증가할수록 높게 나타났으며 terpene을 함유란 세정제들이 hydrocarbon 형태의 세정제와 대응품(CPA, CPB)에 비해 우수한 용해력을 보였다. 그리고, 배합된 세정제들을 함유한 헹굼액은 우수한 유수분리성을 보여 헹굼액의 재활용이 가능하여 경제적인 부담과 수질오염을 줄일 수 있음을 보여주었다. In this study, two kinds of microemulsion-type semi-aqueous cleaning agents that consisted of organic solvent, surfactant, cosurfactant, and water were formulated by changing formulation parameters such as organic solvent type and contents, surfactant type and contents, and cosurfactant/surfactant(A/S) ratio. Physical properties and flux removal of the formulated cleaning agents have also been evaluated. The performance of oil-water separation from the rinse water contaminated during the cleaning process was evaluated for its recycling. The formulated cleaning agents in this work were found to form water-in-oil (W/O) type microemulsion and they were expected to have good penetration because of their low viscosity and low surface tension of 30.2~32.5 dyne/cm. The flux removal with the terpene type cleaning agent was higher than those of hydrocarbon type cleaning agent and two commercial products (CPA, CPB), and the solubility increased with hydrophobicity of the nonionic surfactant. The performance of oil-water separation from the rinse water containing formulated cleaning agent and soils was found to be very good. Therefore, the cleaning agents formulated in this work seemed to have good cleaning efficiency to have economical advantage and water pollution reduction by recycling the rinse water.

고석봉,이재열,이영기,박윤기,이두진,이태형,이승호,Koh, Seok-Bong,Lee, Jae-Yeoul,Lee, Young-Gi,Park, Yoon-Kee,Lee, Doo-Jin,Lee, Tae-Hyung,Lee, Sung-Ho 영남의대학술지편집위원회 1994 Yeungnam University Journal of Medicine Vol.11 No.1

1991년 5월 1일부터 1993년 7월 31일까지 영남대학교 의과대학 부속병원 산부인과에서 시행한 136례의 골반경수술에서 다음과 같은 결론을 얻었다. 환자의 나이 분포는 19세에서 55세였고 평균 나이는 31.2세였다. 평균 분만력은 0.96이었으며 거의 대부분의 환자는 2회 이하의 분만력을 보였다. 골반경수술의 가장 많은 적응증은 난관 임신이었고 그 다음으로는 난소낭종이었다. 시술 방법은 주로 난관절제술(58.8%)과 난소난관절제술(16.3%)이었고 입원기간은 평균 2.1일이었고 모든 경우에는 특별한 합병증이 없었다. 이러한 연구결과로 보아 골반경수술은 경제적으로나 사회적으로 또 미용학적으로도 좋은 결과를 보였으며 앞으로 다른 많은 부인과 환자에게 안전하게 적용할 수 있으리라 사료된다. The aim of this study was to identify the usefulness of pelviscopy in treatment besides its diagnostic value. The advantages of pelviscopic surgery are low cost, rapid recovery, good cosmetic effect, low incidence of complication and postoperative adhesion. So most of the pelvic exploration in gynecologic patients are replaced by the pelviscopic surgery these days. Pelviscopic surgery was performed on 136 patients at the Department of Obstetrics and Gynecology, College of Medicine, Yeungnam University from May 1991 to July 1993. The results obtained were as follows : The age distribution of the patients was from 19 to 55 with age of 31.2 years, and the mean parity was 0.96, the most common indication of pelviscopic surgery was tubal pregnancy(66.9%), the second most common indications was ovarian cyst(10.3%) and the other indications were endometriosis, corpus luteum cyst rupture, parovarian cyst, foreign body, tubal ligation, hydrosalpinx, uterine myoma and diagnostic procedure. The main types of surgery were salpingectomy in 58.8% and salpingoophorectomy in 16.3%. The mean duration of hospitalization was 2.1 days without specific complications. According to these results, it was postulated that the pelviscopic surgery was a useful operative tool in gynecologic treatment and its application could be extended to many other areas of gynecology with safety by the development of surgical techniques and instruments.
