Objective : Our purpose of this study is to evaluate the effectiveness of the transcatheter arterial embolization for the management of abnormal uterine bleeding. Materials and Methods : 14 patients with massive or recurrent uterine bleeding underwent percutaneous transcatheter arterial embolization between February 2003 and September 2004. We reviewed 14 cases of uterine artery or internal iliac artery embolization using gelfoam or PVA particles. Results : Good management of uterine bleeding was achieved in 13 of 14(93%) cases. The cause of abnormal uterine bleeding was myoma(5 case), post D & E bleeding(3), acquired vascular malformation(3), pseudoaneurysm(1), adenomyosis(1), and endometrial hyperplasia(1). Conclusion : Transcatheter artery embolization is an effective and life-saving procedure in massive or recurrent uterine bleeding. Early diagnosis and prompt transcatheter arterial embolization is a useful mangement of uterine bleeding.

The composition of wastewater from dyeing and textile industry is highly variable depending on the dyestuff type. generally the wastewater has high levels of Chemical Oxygen Demand (COD) and color. The decolorization, Total Organic carbon (TOC) removal and petnleate flux used were examined using reactive yellow 84 as dye and ceramic membrane process. On addition, dye particle size distribution, clean water flux and Molecular Weight Cut-Off (MWCO) were measured. The backflushing results show that best permeate flux was obtained when backflushing was performed 3 seconds every 2 minutes at A bar from the pei meaty side. the backflushing frequency and pulse were the most important factors affecting the permeate flux.

This study evaluated the compression force at the L5/S1 disc using back strength and IEMG(Integrated Electromyography). We divided the distance into one-half, three-fourth and full, measured the back strength. The results showed significant difference much among the cases. IEMG values were analyzed under the condition of fixed vertical factor, two horizontal factors, and 2 times per minute for the stoop posture, As the result, there are significant differences between horizontal distance 35cm and 55cm. This result showed that back strength decreased and the motor units of erector spinae muscle increased as the horizontal distance increased. Therefore, decreasing the horizontal distance to decrease compression force at L5/S1 is important on preventing a low back pain. Also. by using these data for prediction musculoskeletal disorders if we design equipment, machine and apparatus for human welfare, we can give advantage of prevention of low back pain much. We will be able to apply these data to work method or workplace lay-out.

영어의 주제화구문과 주어-조동사 도치 전치구문

양상백,안동환 釜山大學校 人文學硏究所 1998 人文論叢 Vol.52 No.1

본 논문에서는 주제화구문 분석의 선행연구에서 알 수 있듯이 주제화구문에 대한 이론적인 발전단계는 단문과 매입문에서의 wh~요소와 주제화요소간의 순서적인 현상을 설명하려는 노력과 관련이 있다는 사실을 살펴보았다. 즉 매입문에서의 이들 현상에 대한 설명력은 CP-지정어 분석과 IP-부가 분석보다 CP-반복 분석이 훨씬 우월하나 단문에서 부정요소 전치구문과 전형적인 주제화요소가 함께 나타날 경우 CP-반복 분석은 이를 올바르게 설명하지 못함을 살펴보았다. 이러한 선행연구의 문제점은 주어-조동사 도치와 상관없이 모든 전치구문을 주제화구문이라고 분석한데서 기인한다. 따라서 이 연구에서는 주어-조동사 도치를 수반하는 전치요소(초점요소)가 전형적인 주제화요소와 서로 다른 특성을 지니고 있음을 논증하고 통사적·의미적 차이점, 분포적 상관관계, 전치요소간의 어순상이 특징을 살펴보았다. Rochemont(1986)이 제시한 대조적 초점해석의 정의는 담화상에서 뿐만 아니라 통사적인 구문인 주어-조동사 도치를 수반하는 전치구문에도 적용될 수 있음을 살펴보았다. This paper deals with Topicalization and Subject-Auxiliary Inversion constructions in English. It suggests that a proposed element of these constructions involves a contrastive meaning, contrary to that of topicalization and argues that subject-auxiliary inversion constructions are contrastive focus constructions. Pointing out some problems with the previous research on topicalization, it discusses some differences between topicalization and the preposing constructions of adverb or negative phrases triggering a subject-auxiliary inversion, based ontheir syntactic and semantic differences, and hierarchical order among a wh-element, a topicalized element and a proposed element (focused element) in the simple clause as well as the embedded clause. It is thus proposed that the inversion constructions can also be applied for Contrastive Focus Interpretation suggested by Rochemont(1986).

The purpose of this study is to provide the basic data of the evaluation methodology in order to apply the ergonomic program for industrial workplace. The result is helpful to establish the improvement alternatives that considered the assessment tools suitable work characteristics in order to prevent musculoskeletal disorders in workplace. We analysed the collected data of workers complaining of musculoskeletal-related pains during 4 months using musculoskeletal administration program(WinCare). As the results, the pained workers had mostly a pain in low back. The results showed that the pained workers in the automotive manufacturing industry pained in several body parts because they worked using the whole body. Also, most of pained workers in the electronic industry and the other industry pained respectively in the upper limb and low back related heavy load handling. That is due to difference of body parts used in each industry. The approach of this study will help to more precise assessment of the ergonomic work postures when establishing the ergonomic improvement plan, especially to consider the application method to workplace using the suitable ergonomic assessment tools classified by type of industry.

Anthor examined the small water supply works of 108 which had been excuted in Jenbug region before the year of 1977, and this is the report on the evaluation of the works and the proposed rational methods for the works. It was found that the excuted woks had many faults. Though water works were required the highly specialized abilities in engineering and administration, water works were excuted in too small units of each villagage, and the many fauts of the works were resulted. Accordingly, the method of excuting the water supply works with the larger units bound several villages is proposed as the rationl.

The purpose of this study was to quantitatively prove the asymmetric lifting acts on the risk factor of low back pain by a comparison of muscle activities of spinal loading and muscle strength(hand grip and back strength) between two types of lifting tasks (symmetric and asymmetric). Fourteen male subjects were participated in the experiment. We analysed and compared hand grip force, back strength. EMG(Electromyography), and IEMG (Integrated Electromyography) values for the stoop posture between symmetric and asymmetric lifting tasks using paired t-test. As the result, the back strength decreased in twisting posture. According to the result of EMG analysis, there were significant differences between right and left erector spinae muscle in asymmetric lifting task regardless of load. When subjects lifted boxes of right side, EMG values of left muscle were higher than those of right muscle. As twisting angle increased, EMG values of left muscle increased and EMG values of right muscle decreased. The results of IEMG analysis were similar to the results of EMG analysis. The results of EMG values during lifting indicated that the take-of stage was most stressful.

목적 : 척추에 발생한 전이성 종양 환자들을 대상으로, 수술적 치료를 시행한 환자에 있어서, 술후 생존 기간과 생존 기간 내 동통, 신경학적 증상, 일상 생활 능력 등의 평가를 통한 수술적 치료의 결과에 대하여 보고하고자 한다 . 연구대상 및 방법 : 1996년부터 1999년까지 본원에서 전이성 종양으로 수술적 치료를 받았던 환자중 추시가 가능했던 13례의 환자를 대상으로 하였으며 술 후 생존 기간 및 술 전 및 술 후 추시 중의 동통 양상 및 신경학적 증상의 호전여부, 일상 생활 수행 능력을 분석하였다 . 결과 : 전례에서 술 전 동통을 호소하였으며, 1례에서만 단독 보행이 가능하였고, 1례에서는 앉는 것만 가능하였으며, 11례에서는 앉지도 못하였다. 술 후 평가에서는 전례에서 동통이 감소하였으며, 술전에 신경학적 증상이 보였던 환자 중 75%에서 신경학적 증상이 호전이 나타났으며, 대상환자 중 92%에서 자가 보행이 가능하거나, 앉는 것이 가능하게 되었다. 사망한 환자의 술후 생존기간은 평균 11.2 개월이었다. 결론 : 수술적 치료를 받은 척추의 전이성 골종양 환자에서 술 후 신경학적 증상의 호전, 동통의 감소 및 보행 능력의 호전을 볼 수가 있었다. 따라서 척추의 전이성 종양 환자에 있어, 수술의 적응증이 된다면 수술적 치료를 적극적으로 시행하는 것이 환자의 삶의 질을 향상시킬 수 있다고 사료된다. To evaluate the clinical results of surgical treatment in metastatic spinal tumor patients. Thirteen patients of spinal metastatic tumor, treated by surgical methods, in this hospital from 1996 to 1999, were included in this study. We analysed pre and post operative pain, neurologic symptom and life quality. Preoperatively, all patients complained of pain and one case do could self walking, one case could do self sitting, and eleven patients were bed-ridden states. Postoperatively, pain was subsided in all cases. Neurologic symptom recovered in 75% of patients who had had preoperative neurologic symptoms. Postoperatively, patients walk or sit without assistance in 92% of cases. Mean postoperative span of survival was 11.2 months. Surgical treatment of spinal metastatic tumor improved the neurologic status and reduced pain. So, we conclude that if indicated, surgical treatment seems to achieve better results than conservative treatment in spinal metastatic tumor patient.
