        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.

        2007년 대한감염학회 권장 성인 예방접종 권장안

        강진한,김홍빈,손장욱,이상오,정문현,정희진,최영화,최정현,최준용,최희정 대한감염학회 2008 감염과 화학요법 Vol.40 No.1

        In 2007, the Korean Society of Infectious Diseases recommended an immunization schedule for adults residing in Korea. This recommendation includes four categories: standard immunization for healthy persons, supplementary immunization for persons with underlying illnesses, recommendations for health-care personnel and for international travelers. The Standard Immunization Schedule consists of universal vaccination (tetanus-diphtheria/tetanus-diphtheria-pertussis (Td/Tdap); hepatitis A vaccine for persons aged 20s; human papilloma virus vaccine for women under 26 years old; meningococcal vaccine for military recruits and college students in dormitories; influenza vaccination for persons aged 50 years or more and pregnant women; and pneumococcal vaccination for persons aged 65 years or more) and catch-up vaccination (hepatitis A vaccine for persons aged 30s; hepatitis B vaccine, varicella and MMR vaccines for persons who have uncertain specific immunities). The Supplementary Immunization Schedule recommends 4 vaccines, i.e., pneumococcal, influenza, meningococcal, and Haemophilus influenzae type b, appropriate to the underlying illnesses, and confirmation of the presence of antibodies to hepatitis A and hepatitis B. The Recommendation for Health-Care Personnel includes universal vaccination (influenza and pertussis) and catch-up vaccination (hepatitis B, measles-mumps-rubella and varicella for seronegative health-care personnel). The Recommended Immunization for International Travelers focuses reinforcement of vaccinations for healthy persons and includes certain immunizations necessary for international travel (yellow fever, meningococcal, plaque, tick-borne encephalitis, and cholera). These guidelines can be seen at www.ksid.or.kr.

        텔레비젼(TV)생산업체 근로자들의 영상단말기(VDT)작업이 시력과 안증상에 미치는 영향

        우극현,최광서,정영연,한구웅,박정한,이종협,Woo, Kuck-Hyeun,Choi, Gwang-Seo,Jung, Young-Yeon,Han, Gu-Wung,Park, Jung-Han,Lee, Jong-Hyeob 대한예방의학회 1992 예방의학회지 Vol.25 No.3

        This study was conducted to evaluate the effect of VDT work on eyes and vision among workers in a TV manufacturing plant. The study subjects consisted of 264 screen workers and 74 non-screen workers who were less than 40 years old male and had no history of opthalmic diseases such as corneal opacities, trauma, keratitis, etc and whose visual acuity on pre-employment health examination by Han's test chart was 1.0 or above. The screen workers were divided into two groups by actual time for screen work in a day : Group I, 60 workers, lesser than 4 hours a day and group II, 204 workers, more than 4 hours a day. From July to October 1992 a questionnaire was administered to all the study subjects for the general charateristics and subjective eye symptoms after which the opthalmologic tests such as visual acuity, spherical equivalent, lacrimal function, ocular pressure, slit lamp test, fundoscopy were conducted by one opthalmologist. The proportion of workers whose present visual acuity was decreased more than 0.15 in comparison with that on the pre-employment health examination by Han's test chart was 20.6% in Group II. 15.0% in Group I and 14.9% in non-screen workers. However, the differences in proportion were not statistically significant. The proportion of workers with decreased visual acuity was not associated with the age, working duration, use of magnifying glass and type of shift work (independent variables) in all of the three groups. However, screen workers working under poor illumination had a higher proportion of persons with decreased visual acuity than those working under adequate illumination (P<0.05) . The proportion of workers whose near vision was decreased was 27.5% in Group II, 18.3% in Group I, and 28.4% in non-screen workers and these differences in proportion were not statistically significant. Changes of near vision were not associated with 4 independent variables in all of the three groups. Six out of seven subjective eye symptoms except tearing were more common in Group I than in non-screen workers and more common in Group II than in Group I (P<0.01). Mean of the total scores for seven subjective symptoms of each worker(2 points for always, 1 point for sometimes, 0 point for never) was not significantly different between workers with decreased visual acuity and workers with no vision change. However, mean of the total scores for Group II was higher than those for the Group I and non-screen workers (P<0.01). Total eye symptom scores were significantly correlated with the grade of screen work, use of magnifying glass, and type of shift work. There was no independent variable which was correlated with the difference in visual acuity between the pre-employment health examination and the present state, the difference between far and near visions, lacrimal function, ocular pressure, and spherical equivalent. Multiple linear regression analysis for the subjective eye symptom scores revealed a positive linear relationship with actual time for screen work and shift work(P<0.01). In this study it was not observed that the VDT work decreased visual acuity but it induces subjective eye symptoms such as eye fatigue, blurred vision, ocular discomfort, etc. Maintenance of adequate illumination in the work place and control of excessive VDT work are recommended to prevent such eye symptoms.

        증기발생기 전열관의 내면 축방향 균열에 대한 ECT 특성 평가

        최명식,허도행,이덕현,박중암,한정호 한국비파괴검사학회 2001 한국비파괴검사학회지 Vol.21 No.5

        증기발생기 전열관에서 1차측 응력부식균열의 발생빈도가 증가하고 있으므로 이의 정확한 탐지와 평가를 위해서는 균열 형상에 따른 와전류 신호특성을 규명하고 적합한 탐촉자를 선정하는 것이 매우 중요하다. 본 연구에서는 증기발생기 전열관의 내면 축방향 균열에 대한 와전류 검사의 검출능과 크기예측에 대한 신뢰도를 정량적으로 평가하고 pancake coil과 plus coil과의 신호특성 차이를 비교하였다. 이를 위하여 전열관 내면에 EDM으로 노치를 가공한 시편과 실제 증기발생기에서 1차측 응력부식균열이 발생하여 인출한 전열관을 시험편으로 사용하였다. 본 연구에서 얻어진 결과를 토대로 내면 축방향 균열에 대한 와전류 검사 신뢰도 향상을 위한 방안을 제시하였다. For the enhancement of ECT reliability on the primary water stress corrosion cracks of unclear steam generator tubes, of which the occurrence is on the increase, it is important to comprehend the signal characteristics on crack morphology and to select an appropriate probe type. In this paper, the sizing accuracy and the detectability for the inner wall axial cracks of tubes were quantitatively evaluated using the following specimens: the electric discharge machined notches and the corrosion cracks which were developed on the operating steam generator tubes. The difference of eddy current signal characteristics between pancake and axial coil were also investigated. The results obtained from this study provide a useful information for more precise evaluation on the inner wall axial cracks of steam generator tubes.

        흰쥐의 발치와에 이식한 단계별 치아싹의 발육 과정

        정희훈,정한성,김성오,최형준,이제호,최병재 大韓小兒齒科學會 2008 대한소아치과학회지 Vol.35 No.2

        The purpose of this study is to evaluate at which stage of tooth germ would develop into normal calcification and hence to increase the success rate of transplantation. Therefore, tooth germs on the 15th, 17th embryonic day and the 3rd day of birth were separated for allotransplantation into maxilla of adult rat of 11 weeks. Calcification processes were analyzed radiographically and histopathologically at 4 weeks and 8 weeks after allotransplantation. The results are as follows: 1. Allotransplanted tooth germ at 4 weeks and 8 weeks showed delayed calcification compared to that of normal odontogenesis. 2. At 4 weeks, abnormal calcified tissue, such as odontoma and ankylosis of osteodentin with surrounding alveolar bone were observed. 3. At 8 weeks, allotransplanted tooth germs of the 15th and 17th embryonic day showed calcification and osteodentin surrounded by periodontal ligament. 4. At 8 weeks, allotransplanted tooth germs of the 3rd day of birth showed calcification composed of cementum and osteodentin. In this study, we observed small sized and amorphous calcified tissue from allotropic allotransplantation of tooth germs. Since these calcified tissue were underdeveloped and shaped irregularly, for calcification into normal tooth form, further study needs consideration about the reduction of surgical trauma, developmental stage of transplanted tooth germ, blood supply from recipient site, fixation method in transplanted site and period of transplantation. 외상이나 치주 질환,유전적 결함 등에 의하여 치아가 상실되었을 경우,보철 수복이나 임플란트로 치료하고 있다. 그러나 보철 수복이나 임플란트는 자연치가 아닌 인공치를 이용한 치료로서 기능성과 섬미성 등에서 자연치에 비하여 한계 가 있으므로 자연치를 이용한 이식 방법에 관심이 증가하고 있으며 치아 이식의 성공률을 높이기 위한 이식 치아의 발육과 성장에 대한 연구가 진행 중이다. 이 연구는 세 가지 단계의 치아싹을 발치와에 동종 이식하고 치아싹이 발육하여 석회화가 이루어지는지 평가하기 위하여 임선 15일과 17일,출생 후 3일 된 흰쥐의 치아싹을 분리하여 11주 된 흰쥐의 발치와에 이식하고 4주와 8주 후 방사 선학적 그리고 병리조직학적으로 석회화 과정을 관찰하여 다음과 같은 결과를 얻었다. 1. 발치와에 이식된 임신 15일과 17일,출생 후 3일 된 치아싹에서 4주와 8주 후 석회화된 조직이 형성되었다. 2. 임신 15일과 17일,출생 후 3일 된 치아싹을 발치와에 이식하고 4주 후 치아종 같은 비정상적인 석회화 조직과 인접 치조골과 유착된 골양상아질이 관찰되었다. 3. 임신 15일과 17일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질이 보였으며 치주인대로 둘러싸인 것도 관찰되었다. 4. 출생 후 3일 된 치아싹을 발치와에 이식하고 8주 후 골양상아질과 백악질이 형성되었다. 이 연구는 치아싹을 흰쥐의 발치와에 이식한 후 치아싹의 발육을 관찰한 것으로 이식 조직에서 크기가 작고 무정형의 석회화 조직이 형성되었다. 정상적인 치아보다 형태가 불규칙하고 발육이 늦었으므로 이식된 치아싹이 정상적인 치아 형태로 석회화되도록 하기 위해서는 이식 조직의 발육 정도와 이식 조직을 절제할 때 외과적 손상의 감소,치아싹으로의 풍부한 혈류 공급,이삭 기간,이식 조직의 고정을 고려하여 더 많은 연구가 필요할 것으로 생각된다.
