Objective: Burch operation has been effective method for the treatment of stress incontinence. Burch operation is a well-accepted procedure for treating stress urinary incontinence secondary to urethral hypermobility without intrinsic sphincter deficiency and is the reference standard with which other procedures are compared. This study is to evaluate the effectiveness of the Choi`s hook in laparoscopic Burch operation. Methods: This study included 47 patients who had undergone laparoscopic Burch operation from October 2000 through March 2005. Of these 47 patients, 27 patients underwent traditional laparoscopic Burch operation (Group 1) and 20 patients underwent laparoscopic Burch operation with Choi`s Hook on anchoring the endopelvic fascia to the Cooper`s ligament (Group 2). Results: The mean age of patients of Group 1 was 55.6±9.37 years of age and that of Group 2 was 56.0±5.93 years of age. There is no difference in the mean age of patients (P>0.05). The mean operating time was 90.5±15.32 minutes for Group 1 and 38.5±10.14 minute for Group 2. The mean operating time was shorter in Group 2 than Group 1 (P<0.05). There was no difference in recurrence rate and complication rate between Group 1 and Group 2 (P>0.05). Conclusion: We performed laparoscopic Burch operation with the Choi`s Hook on anchoring the endopelvic fascia to the Cooper`s ligament. When we compared traditional laparoscopic Burch operation with laparoscopic Burch operation with Choi`s Hook, we could shorten the operation time using the Choi`s Hook.

Influence of Gas Nitriding on the Damping Capacity of Fe‑17Mn Alloy

Seon‑Min Choi,Ji‑Sook Park,Kyongjun An,이영국 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.1

Fe-17Mn alloy has been attracted as a high damping alloy due to its excellent damping capacity and tensile properties. For itsindustrial application, it is necessary to improve both wear resistance and anti-oxidation. To solve this problem, gas nitridingwas performed at 520 °C for 10 h using cold-rolled specimens. The nitrided specimen revealed a thick nitride layer of~ 68 μm with ~ 20%Mn and a hardness value of ~ 650 Hv on the matrix of ε martensite and γ austenite without the diffusionlayer. The damping capacity of the nitrided specimen was decreased with increasing the thickness ratio of nitride layer tomatrix. However, when the thickness ratio was ≤ 1.5%, the damping capacity of the nitrided specimen was similar to that ofthe nitride-free specimen. This indicates that the wear resistance and anti-oxidation of Fe-17Mn alloy can be improved bya thin nitride layer without the loss of its damping capacity.

Baik, Jee-Seon,Huh, Kyung-Hoe,Park, Kwan-Soo,Park, Moo-Soon,Heo, Min-Suk,Lee, Sam-Sun,,Choi, Soon-Chul 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

Coronoid impingement can cause limitation of mouth opening. In many cases, it appears to be related to the coronoid hyperplasia. We present a case of mouth opening limitation caused by coronoid impingement on the posterior surface of the zygomatic bone without coronoid hyperplasia. The bony changes in coronoid and zygoma including surface irregularity and discontinuity of the cortex and sclerotic change of inner medullary space were noted on computed tomography (CT) scans in different level of axial planes. Through another CT scans in open mouth position could demonstrate that those bony changes were caused by the contact of both surfaces against each other. In case coronoid impingement is suspected of the many possible causes, the open mouth CT scans will be needed to reveal the direct impingement of coronoid on zygoma even without coronoid hyperplasia.

「獻花歌」에 대한 祭儀的 考察

최선경 연세대학교 인문과학연구소 2002 人文科學 Vol.84 No.-

This study examined the background story of 「Hunwhaga」 in 『Samgukyusa』 from a ritual point of view. The background story of 「Hunwhaga」 handed down from the verse 「Madame Suro」 tells that when Madame Suro desired flowers on a thousand-jang-high cliff on her way to follow her husband who was appointed as a taesoo in Kangreung, an old man passing by picked the flowers and presented them to her singing. Though there have been many interpretations of the background story of 『Hunhwaga』, those discussions can be divided into two in general: one is that the story is about a courtship of an old man who was charmed by the beauty of Madame Suro and the other is that the story is a record of an event which occurred during the rite. Taking symbolism of words appearing in the story into consideration, I believe that the background story of 「Hunwhaga」 should not be interpreted as a love story in an earthly life but a record of a ritual event which occurred during the rite. The ritual representations shown in the background story of Hunwhaga, are haejung(海汀), joosun(晝饍), suckjang(석장), sea, flowers, and so on. Haejung is more of a ritual space than a mere coast and joosun symbolizes the foods offered to a god during the rite rather than an everyday lunch. In the light of the facts that water represents abundance, restoration, and creation and rocks symbolize a center, suckjang and sea are believed to indicate that the space is newly created and divine. In shamanisam, flowers are generally considered to have a divine nature with ability of incantation or deification. Likewise, the flowers on a thousand-jang-high suckjang in the background story of 「Hunwhaga」 can be seen as a symbol of descended divinity during the rite and a representation of liveliness. Such ritual representations suggest that the background story of 「Hunwhaga」 should not be interpreted as a simple love story between a man and a woman but regarded as a ritual event. While interpreting the background story of 「Hunwhaga」, the nature of 「Hunwhaga」 should be noted. Until now, a great deal of researchers have considered 「Hunwhaga」, a song sung during the rite, as an incantation song. This is because many researchers looked upon all the songs sung during rites as the ones to have a nature of incantation. However, I believe not all songs sung during rites necessarily mean that they have a nature of incantation because incantation is defined as 'to obtain one's own purpose borrowing the power of a supernatural existence' but 「Hunwhaga」 itself does not wield such power. Since 「Hunwhaga」, is a song of divinity responding to the prayer of Madame Suro during the rite, it is certainly a ritual song but not a song of incantation. Therefore, this study asserts that regarding 「Hunwhaga」, as a song of incantation should be reconsidered.

최영현,박건영,이선미,유미애,이원호 부산대학교 유전공학연구소 1995 분자생물학 연구보 Vol.11 No.-

The inhibitory effect of the fresh juice of kale on the genotoxicity induced by aflatoxin B_1 (AFB_1) in Salmonella and Drosophila was investigated. The kale juice had strong inhibitory activity for His^- to His^+ reverse-mutations induced by AFB_1 acting on S. typhimurium TA100. A similar inhibitory effect was detected in somatic cell mutation assaying system of D. melanogaster. Using the wing hairs spot test, we found that the formation of mutant hairs in adult flies as a result of feeding with AFB_1 in their larval stages was efficiently inhibited by coadministration of the fresh juice of kale, which revealed that it can inhibit gene mutation, deletion and mitotic chromosomal recombination. These results seem to suggest that kale juice may exert its inhibitory effect to mutagenic and/or carcinogenic properties of DNA damaging agents.

소아의 치아우식증을 예방하기 위한 불소의 국소도포는 소아치과 영역에서 널리 시행되고 있다. 하지만 이러한 잇점에도 불구하고 최근 수복물 표면을 거칠게 한다는 부작용에 대해 논란이 되고 있다. 이에 본 연구에서는 불소도포가 심미 수복물의 표면변화에 미치는 영향을 평가하기 위해 수종의 복합레진에 국소도포용 불소젤을 도포시킨 후 변화를 관찰하였다. 시판용 레진인 Z 250(3M ESPE, USA), Ultraseal XT^(®)(Ultradent, USA), Filtek flow^(®)(3M, USA) , Revolution^(®)(Kerr, USA), Denfil^(®)(Vericom,Korea)를 이용하여 시편을 제작하고, 불소젤은 Topex^(®)(Sultan Dental Products,Canada)을 각각 1분과 4분동안 도포시켰다. 각 제품마다 불소젤을 도포하지 않은 5개의 시편을 대조군으로 사용하였다. 그 후 이 시편들의 표면 거칠기(Ra value,㎛)와 무게 차이를 측정하고 주사전자현미경을 이용하여 다음과 같은 결과를 얻었다. 1. 불소젤을 도포시키지 않은 대조군에서 가장 평활한 표면을 보였으며 1분군, 4분군 순으로 표면 거칠기가 증가하였다. 그리고 Revolution을 제외한 모든 제품에서 유의한 차이를 보였다(p<0.05). 2. 국소도포용 불소젤을 도포한 각 레진 시편의 무게 차이를 비교한 결과 대조군, 1분군, 4분군 간에 유의한 차이는 없었다(p>0.05). 3. 주사전자현미경 관찰시 불소젤에 도포시킨 실험군은 대조군에 비해 거친 표면을 나타냈다. 이상의 결과로 국소적 불소도포는 복합레진의 표면 거칠기에 영향을 미치며 이를 고려하여 사용한다면 4분보다는 1분간의 불소도포법을 이용하는 것을 추천할 수 있을 것으로 사료된다. Topical fluoride application for children is a widely performed procedure in the field of pediatric dentistry to prevent dental caries. However, it is recently recognized as having some unwanted effects on several esthetic restorative materials as it roughens the surface of the restorative materials. The aim of this study was to evaluate the surface changes in composite resins to topical fluoride. Composite resins(Z 250^(®),Ultraseal XT^(®),Filtek flow^(®),Revolution^(®),Denfil^(®))in topical fluoride agents were immersed and their surface roughness, weight loss and SEM were evaluated. The results were as follows: 1. The 4 minutes-immersion groups showed more roughened surface than 1 minute-immersion groups and the control groups showed the smoothest surface among all the materials, and there was statistically significant difference except the revolution between the groups. 2. There was no significant difference between the 1 minute-immersion groups and 4 minutes-immersion groups in weight loss. 3. The experimental group treated with topical fluoride gel showed the generally mere roughened surface than control group in the SEM findings.
