지난 '96년 한국통신공사 전화교환원의 집단발생(66명 산재승인)을 계기로 사회에 알려지기 시작한 작업관련성 근골격계질환은 '99년부터 증가하기 시작하여, '00년 193.3% 증가(1,009명 발생), '01년 61.9% 증가(1,634명 발생), '02년 11.8% 증가(1,827명 발생)하여 최근 5년간 1,000%이상의 폭발적 증가율을 보이고 있다. 한편. 전체 업무상질병 중 차지하는 비율도 매년 증가하고 있다('00년 24.9%, '01년 28.9%, '02년 33.7%).(중략)

Purpose: We wanted to assess the long-term follow-up MR (LTFU-MR) imaging of adenomyosis that was treated with uterine artery embolization (UAE). Materials and Methods: From 1998 to 2000, 22 patients who underwent UAE for symptomatic adenomyosis were enrolled. The pattern of adenomyosis was divided into two categories: focal (n=14) and diffuse type (n=8). All the patients underwent contrast-enhanced MR imaging 3 months before embolization and over 3 years after embolization. The MR findings for the volume change and the existence and alteration of necrosis were analyzed. Results: In the focal adenomyosis, LTFU-MR revealed contrast enhancement in the completely necrotized area before in five out of seven patients and persistent necrosis with atrophy in the remaining two cases. In the six cases without necrosis, four showed global enlargement of the uterus. In the eight patients with diffuse adenomyosis, LTFU-MR revealed contrast enhancement in the necrotized area in four of the patients. Of the remaining four patients who had no necrosis, two showed global enlargement of the uterus. Conclusion: LTFU-MR revealed three common patterns: persistent necrosis or atrophy, viable tissue replacement in the previously necrotized area and global enlargements of the uterus. 목적: 자궁동맥 색전술 후 자궁선근종의 장기추적 자기공명영상(MRI) 소견에 대해 알아보고자 하였다. 대상과 방법: 1998년부터 2000년까지 선근종으로 색전술을 시행한 환자 중 3년 이상 경과한 MRI를 시행 받은 22명의 환자를 대상으로 하였다. 선근종은 국소형이 14예, 미만형이 8예 였으며 평균 연령은 38세였고 평균 추적기간은 4.9년이었다. 색전술 후 3개월 및 장기추적 MRI에서 괴사의 유무 및 자궁의 용적 변화에 대해 분석하였다. 결과: 국소형 선근종의 경우, 총 14명의 환자 중 완전 괴사를 보였던 7명 중 5명의 환자에서 장기 추적 MRI 상 괴사하였던 부위에 조영 증강이 관찰되며 viable tissue로 대체되었으며 2예에서는 지속적인 괴사와 함께 자궁의 위축이 더 진행되는 소견을 보였다. 괴사를 전혀 보이지 않았던 6예 중 4예에서 자궁 용적의 증가를 볼 수 있었다. 미만형 선근종의 경우 총 8예 중 색전술 후 완전 혹은 부분 괴사를 보인 4예 모두에서 장기 추적 MRI 에서 조영 증강이 다시 관찰되었고, 괴사를 보이지 않았던 나머지 4명 중 2명은 자궁용적의 증가를 보였다. 결론: 자궁동맥색전술 후 선근종의 장기 MRI 영상은 지속적인 자궁위축과 괴사, 괴사된 부위가 다시 조영증강 되는 viable tissue로의 대체 및 자궁용적의 증가로 요약될 수 있었다.

Objectives : To investigate the changing pattern of medical utilization claims following the economic crisis in Korea. Methods : The original data consisted of the claims of the 'Medical insurance program of self-employees' between 1997 and 1998. The data was selected by medical treatment day ranging between 8 January and 30 June. Medical utilizations were calculated each year by the frequency of claims, visit days for outpatients, length of stay for inpatients, total days of medication, and the sum of expenses. Results : The length of stay as an inpatient in 1998 was decreased 4.7 percent in comparison to 1997. However, inpatient expenses in 1998 increased 10.8 percent as compared to 1997. Inpatient hospital claims in 1998 increased 6.2 percent over 1997, although general hospital inpatient claims in 1998 decreased 3.3 percent in comparison to 1997. The outpatient claim frequency decreased 7.3 in 1998 percent as compared to 1997 Outpatient visit days of in 1998 were decreased 8.5 percent in comparison to that recorded in 1997. Outpatient claim frequencies of 'gu region' in 1998 decreased 10.5 percent comparison to that in 1997, but 'city and gun region' decreased less than 'gu region'. Conclusions : Medical utilization in 1998 deceased in relation to 1997 Medical utilization by outpatients decreased more than that of inpatients. Medical utilization by 'gu region' decreased mere than the other regions.

The study is conducted in order to establish validity of industrial safety field's neo-qualification composition by suggesting reengineering procedure of NCS based industrial safety field's qualifying occupational plan. Industrial safety fields are first classified into great classification which are environment·energy·safety, and then into sub-classification which are industrial safety management, industrial health management, and nondestructive test. NCS based neo-qualification plan is deveopled into progress as following steps; First, planning NCS neo-qualification system. Second, presenting work·education combined program certification standard. Third, developing NCS based neo-qualification assessment standard. Fourth, developing work·education qualification prototype problem. The process of qualification plan was composed with Worksheet 14 and with 4phase being completing summary of each section, certification and development of assessment standard, and development of prototype problem. As a result, Industrial safety manager was redesigned into Industrial sfety manager and Construction Safety Manager, and Occupational Health Care Manager was redesigned into Occupational Health Care Manager and Industrial Health Manager. This study, in conclusion, suggests development of qualifying occupation that could be applied to the integrated management system and development of future industrial safety field's specialized neo-qualifying occupation.
