Objective To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi’s LM) and conventional 4-port LM. Methods A retrospective study of patients who underwent Choi’s LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. Results The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi’s LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi’s LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi’s LM were acceptable. Considering its usability, Choi’s LM is feasible for the treatment of uterine leiomyoma.

The high pressure vapor-liquid equilibrium data are essential in order to separate the mixture of toluene and p-xylene with supercritical carbon dioxide. The circulation type vapor-liquid equilibrium apparatus has been used during this research to get ternary data of toluene, p-xylene and carbon dioxide system. The ternary phase liquid-vapor equilibria of carbon dioxide, toluene and p-xylene were measured for pressures ranging from about 26 bar to the 100 bar at 100℃. The liquid phase composition of carbon dioxide and the sum of vapor phase compositions of toluene and p-xylene are increased as the pressure is increased.

목 적 : 하청노동을 이용한 노동 유연화 전략은 근로자들의 고용을 불안정시키고, 근로자들의 삶에 부정적 영향을 미치고 있다. 따라서 이 연구는 하청업체 근로자들의 고용현황을 조사하고, 기존의 업체중심의 건강평가의 문제점을 지적하고자 하였다. 또한 하청업체 근로자들의 건강평가의 현재적 의미와 사회적 배제의 특성을 알아보고자 하였다. 방 법 : 모기업과 하청업체 근로자들의 건강수준을 비교하기 위하여, 정기건강진단(일반, 특수)과 채용건강진단 자료를 이용하고자 하였다. 건강진단에서 누락된 비정규직을 포괄하기 위하여 SF-36을 이용하여 건강설문조사를 시행하였다.결 과 : 조선업 하청업체 근로자들의 고용기간은 짧고, 빈번한 노동이동 현상을 보였다. 3년간 건강진단 수검 현황을 통해 살펴볼 때, 1998년 수검자중 2000년까지 연속해서 검진 받은 수검자는 40.3%였다. 건강진단 결과 유소견자 규모를 통해 모기업과 하청업체간의 건강수준을 비교해 보았다. 모기업은 일반질병 요관찰자와 질병자를 포함한 유소견자가 1,011명으로 약 10 %의 유소견율을 보이고 있고, 질병자의 경우 596명으로 유병률이 5 %를 상회하고 있다. 반면 하청업체의 경우 1,967명의 수검자중 유소견자가 115명으로 6 %의 유소견율을 보이고있고, 질병자는 82명으로 4 %의 유병률을 보이고있다 채용건강진단을 받은 수검자는 6,260명 이었으며, 이 중 유소견자 수는 2,373명으로 전체 수검자의 37.9 %를 차지하였다. 건강설문지의 경우는 전체 건강수준의 총합은 하청보다 원청 근로자가 높았고 통계적으로 유의하였다. 결 론' 정기건강검진 결과는 하청근로자들이 고용형태에 따라 검진을 받지 못한 경우가 많아, 건강 근로자 효과로 표현될 가능성이 있다. 따라서 채용건강진단 결과는 다른 측면에서 하청업체 근로자들의 건강수준의 현실적 반영이라고 할 수 있다. 향후 하청업체 근로자들의 건강문제를 감시하고 개선하려면 기존의 업체 중심의 접근으로는 하청 근로자의 건강문제를 제대로 다룰 수 없고, 업종과 지역을 동시에 고려하여 접근할 필요가 있다. 또한 단기 고용 근로자 및 비정규직 근로자를 사회보장의 확충과 모기업의 연대책임 강화 및 기업복지 차원에서 포괄하는 방안이 모색되어야 하겠다. Objectives : The strategy for the labor flexibility through subcontracted labor have brought a negative effect on the lives of the workers, such as the increase of the unstable employment. This study was conducted to analyze the relationship between the employment of subcontracted firms and the health status of them, and to find out some problems which have been caused in the process of health evaluation and the characteristics of social exclusion. Methods : We reviewed the periodical health examination and preemployment health examination in order to compare health status of the subcontracted workers with those of the parent firm workers. The SF-36 questionnaire was administered to assess the self-perceived health status. Results : The result shows that compared to the working duration of the parent firm workers, those of the subcontracted workers were shorter, and the job transfer rate was higher. In the periodical health examination, the prevalence of occupational and general disease was higher in the parent firm(10%) than in the subcontracted firms(6%). Preemployment health examination plays an important role in worker's health manage- ment. Among 6,260 workers who received preemployment health examination, the prevalence of disease was 37.9%. Mean scores of health status measured by SF-36 were lower in the subcontracted firm than in the parent firm. Conclusions : Due to social exclusion of the subcontracted workers from the periodical health examination, there is a possibility that the periodical health examination have the healthy worker effect. These results suggests that the preemployment health examination could be a more appropriate indicator which is able to assess the health status of the subcontracted workers than the periodical health examination.

조수헌,양대현,최헌 大韓産業醫學會 1989 대한직업환경의학회지 Vol.1 No.1

1986년 12월부터 1988년 11월까지 2년간 지방공사 강남병원 고압산소치료센타에 내원하였던 489명의 감압병환자중 신경계증상 등 중증증상을 보인예는 39명이었다. 이중 수산물채취 잠수작업중 중증감압병에 이환되어 미해군 재가압치료표에 따라 치료가 끝난 37명에 대하여 일반적 특성 및 잠수의학적 특성에 관한 자료를 조사하였다. 중증감압병환자의 67.5%가 25∼34세 연령층에 있었으나 10.8%는 45∼49세의 고연령층 이었다. 1년 미만의 잠수경력을 가진 예가 21.6%이었으며, 잠수기술은 70%가 체계적인 교육보다는 현장에서 잠수작업을 거들면서 기술을 습득하였다. 감압병 발병당일의 잠수형태에서는 31∼50m의 수심에서 2∼8회의 반복잠수 후에 흉부통증 또는 하지감각장애 등의 증상이 나타났는데, 증상발현은 수면부상후 30분이내에 83.7 %가 그리고 3시간이내에 100% 나타났다. 증상발현후 재가압치료를 받기까지의 경과시간은 평균 18시간으로, 재가압치료를 받아 완치된 경우에 있어서는 평균 12일의 입원기간중 11.3회의 고압산소요법을 실시하였다. 중증감압병의 경과 및 회복에는 발생전날의 반복잠수와 주증상발현후 재가압 치료까지의 경과시간이 지연되는 경향을 보였다. Hospital records were reviewed for 486 divers who have been diagnosed as decompression sickness(DCS) at Kangnam General Hospital between December 1986 and November 1988. Among 39 cases classified as serious DCS(type II), the patients had been fishery diving in 97.4% of the cases. The ages of the afflicted divers ranged from 22 to 47 years, with a mean of 31.5% years. The divers were experienced being less than one year in 21.6% and 70% of them learned diving skill by self-taught. In 86.5% of the cases the divers had made multiple divies ranged in depth from 31 to 50 meters. Thirty-one(83.7%) of the patients noted their symptoms within 30 minutes of surfacing. The spinal cord was most often affected, and the most common symptoms were 'numbness' or 'tingling' in one or more extremities and discomfort or pain on the chest. Recompression treatment was delayed for 18 hours in average after the onset of dysbaric symptoms and this treatment is more likely to be effective the sooner that it commences after the onset of dysbaric symptoms.
