Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

유재홍,하은희,김수근,김정연,김용규,이의철,이철호,손준석 대한산업의학회 2007 대한직업환경의학회지 Vol.19 No.1

목적: 이 연구는 뇌 · 심혈관 질환으로 업무상재해를 신청한 사례 중에서 승인된 사례와 불승인된 사례의 특성을 비교하여 뇌 · 심혈관 질환의 업무상 재해여부를 판단하는데 필요한 기초 자료를 제공하고자 한다. 방법: 2000년부터 2004년까지 근로복지공단에 업무상 재해로 요양이 신청되어 승인여부가 결정된 뇌 · 심혈관 질환자 12,309명을 대상으로 하였다. 승인여부와 관련된 특성을 확인하기 위해 연도별, 업종별, 규모별, 직업별, 성별, 연령별, 질환별, 생존유무별 그리고 기존질환 유무에 대하여 카이제곱 검정과 다변량 로지스틱 회귀분석을 이용하였다. 결과: 다변량 로지스틱 분석에서 뇌 · 심혈관 질환의 불승인에 대한 승인의 비차비는 광업을 기준으로 하였을 때에 전기가스 상수도업이 4.18(95% CI=1.43~12.17), 건설업이 2.39 (95% CI=1.22~4.69), 제조업이 2.10 (95% CI=1.08~4.07)이었고, 장치기계조작원 및 조립원에 비하여 서비스 근로자 및 상점과 시장 판매근로자 군이 1.90(95% CI=1.47~2.47), 전문가 군이 1.83(95% CI=1.50~2.23), 기술공 및 준전문가 군이 1.63(95% CI=1.35~1.97), 입법 공무원과 고위 임직원 및 관리자 군이 1.62(95% CI=1.24~2.12)이었고, 여성이 남성에 비하여 1.31(95% CI=1.13~1.53), 심장질환에 비하여 뇌혈관질환이 2.75(95% CI=2.42~3.13), 사망한 경우가 생존한 경우에 비하여 6.01(95% CI=4.89~7.38)이었다. 결론: 우리나라에서 뇌심혈관질환으로 업무상 재해를 신청하는 건수는 증가하고 있고 승인율은 비교적 높았으며 승인에 영향을 미치는 요인으로는 업종, 규모, 직종, 성, 연령, 질환, 생존유무 등이 확인되었다. 특히 업종과 직종에 따라서 승인율의 차이가 큰 것이 어떠한 요인의 영향 때문인지에 대한 검토가 필요하고, 특히 뇌실질내 출혈의 경우에 다른 질환에 비하여 승인율이 매우 높았던 것은 업무수행성에 대한 인정기준의 잘못된 적용의 결과 이므로 시정이 필요하겠다. Objectives: This study was performed to provide fundamental data to judge whether or not cerebro and cardiovascular diseases are work-related, by comparing the characteristics between approved and non-approved cases among the worker's compensation claims. Methods: We collected 12,309 cerebro and cardiovascular disease claims based on the worker's compensation records of the Labor Welfare Corporation from 2000 to 2004. The approved and non-approved cases were analyzed according to factors such as the calendar year, industry, company size, occupation, gender, age group, classification of cerebro and cardiovascular diseases, fatality and underlying diseases. We used x²-test and multivariate logistic regression for the analysis. Results: According to multivariate logistic regression, electricity gas and water supply (OR=4.18, 95% CI=1.43~12.17), construction (OR=2.39, 95% CI=1.22~4.69) and manufacturing (OR=2.10, 95% CI=1.08~4.07) industries had a higher approval rate than mining and quarrying industries. Service workers and sales & marketing department workers (OR=1.90, 95% CI=1.47~2.47), professionals (OR=1.83, 95% CI=1.50~2.23), technicians and associate professionals (OR=1.63, 95% CI=1.35~1.97) and legislators and senior officials and managers (OR=l.62, 95% CI=1.24~2.12) had a higher approval rate than plant and machine operators and assemblers. Female workers had a higher approval rate (OR=1.31, 95% CI=1.13~1.53) than male workers. Cerebrovascular diseases had a higher approval rate (OR=2.75, 95% CI=2.42~3.13) than cardiovascular diseases. Fatal cases had a higher approval rate (OR=6.01, 95% CI=4.89~7.38) than surviving cases. Conclusion: For cerebro and cardiovascular diseases, workers' compensation claims are increasing, approval rates are relatively high and factors such as industry, company size, occupation, gender and fatality are related. A remarkable difference in the approval rate was found according to industry and occupation, suggesting the need for further study to identify which factors influence the approval rate. The approval rate for intracerebral hemorrhage arising in the course of employment (COE) was significantly higher than that arising out of employment (AOE), suggesting the need to correct the approval criteria.

This experiment was carried out to evaluate the agronomic stability of North Korean rice varieties using the statistical model developed by Grafius, Finlay, and Ever hart. The lowest yearly variation based on coefficients of variation was found in Hannam 29 for number of panicles per hill, in Sijoong 9 for number of grains per panicle, in Pyeongyang 3 for ripened grain ratio, in Sijoong 16 for 1,000 grain weight, and in Yeomju 1 for grain yield. By Grafius's model, Pyeongbook 3, Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups show stable for 3 years. Weonsan 66 in early maturing groups and Seohaechalbyeo in medium maturing groups were found to be highly stable as analyzed by both Finlay and Wilkinson's model and Everhart & Russell's model. With reference to three models, Weonsan 66 was highly stable for 3 years with showing more yield than Odaebyeo in early maturing groups while Seohaechalbyeo was highly stable for 3 years with showing high yield than Hwaseongbyeo in medium maturing groups above 5~;t~;ha-1 of milled rice respectively.

평야지재배 적응 조생종 벼 품종의 선발 및 품종 육성의 기초 자료로 활용코자 극조생종(1품종)과 조생종(10품종) 및 준조생(3품종)등 총 14품종을 산간지(운봉)와 평야지(익산)에 지역별 표준재배법으로 공시한 결과, 1. 극조생종 및 조생종들은 감온성이 커 산간지에서 출수가 빠르나, 준조생종에 속하는 상미벼, 영덕34호, 히또메보레 등은 감광성이 감온성보다 커, 평야지재배에서 4일정도 빨리 출수하였다. 2. 수량성은 대부분의 품종들이 산간지재배에 비해 평야지 재배에서 높았고 대체로 출수가 빠른 품종일수록 지역간의 수량차가 크게 나타났으며, 출수가 다소 늦은 준조생종들은 산간지와 평야지의 재배에서 수량차가 크지 않아 산간지 뿐만 아니라 평야지에서도 적응성이 높았다. 3. 단백질함량은 숙기가 다소 늦은 품종일수록 낮은 경향을 보였고 산간지보다는 평야지에서 낮았으며, 품종간에는 오대벼, 운봉30호, 영덕34호, 신석조생, 상미벼 등이 함유량이 낮았다. 4. 식미치는 산간지재배가 평야지에 비해 보다 높게 나타났고, 출수가 늦을수록 높았으며, 지역간 차가 크게 나타난 품종은 극조생종인 키라라397이었고, 출수가 늦은 상미벼와 히또메보레는 차가 적었다. 5. 산온도와 수량과의 상관은 산간지에서만 영향이 있을 뿐 평야에서는 영향이 적고 일사량과 일조시수가 수량에 보다 상관성이 높았으며, 식미치는 적산온도와는 부의상관, 생육 일수와는 정상관을 보였다. This experiment was carried out to clarify the difference of rice yield and the quality of rice in southern plan area and in alpine area. Yield and quality of fourteen early varieties were investigated under the different transplanting dates and planting densities in southern plan area(Iksan) and in alpine area(Unbong). In the alpine area, extremely early variety and early varieties headed early compared to the plain area, but medium early varieties headed about 4 days late unlike the alpine area. The yield difference of most early varieties including Kilara 397 of extremely early flowering variety were greater in plain area than in alpine. The different of yield between plain and alpine area was less in varieties with Sinseogjosaeng, Odaebyeo, Akidagomachi, and Yeungdeuk34. The rate of protein was lower in plain area than alpine and more lately flowering than early, but palatability of milled rice was higher at the alpine area and more lately flowering varieties. Correlation coefficients between yield and meterological data during maturity, yield shower the significant correlation with integrated solar radiation and sunshine hours at cultured in southern plan area, but it showed only cumulative temperature in alpine area. Palatability of miller rice was positive correlation at growth duration but negative correlation at cumulative temperature.

박찬원(Chan-Won Park),손연규(Yeon-Kyu Sonn),장용선(Yong-Seon Zhang),홍석영(S. Young Hong),현병근(Byung-Keun Hyun),송관철(Kwan-Cheol Song),하상건(Sang-Keun Ha),문용희(Young-Hee Moon) 한국토양비료학회 2010 한국토양비료학회지 Vol.43 No.6

본 연구에서는 1:25,000 정밀토양도 등 가용한 공간자료를 이용하여 작성된 토양유실도를 이용하여 한강 상류지역 10개 중권역 108 소유역에 대하여 토양유실량 평가하고 토지이용별 토양유실 위험지역을 분석하였다. 대상유역 총 토양유실량은 895만 Mg yr<SUP>-1</SUP>으로 예측되었으며, 면적당 평균 토양유실량은 6.1 Mg ha<SUP>-1</SUP>yr<SUP>-1</SUP>이었다. 중소유역 단위로 살펴보면 남한강지역이 북한강지역의 유실량 뿐만 아니라 면적당 유실량이 더 많았다. 이는 북한강 권역의 경우 화강암 및 화강편마암이 주요 모재인 반면에 남한강 권역의 경우 토양모재가 퇴적암지대를 많이 포함있어 토양침식성 인자 (K factor)와 경사 인자 (LS factor)가 상대적으로 높고, 남한강 지역의 경우 농경지 토양이 상대적으로 많이 분포하고 있기 때문으로 판단된다. 대상유역의 토지이용별 연평균 토양유실량을 분석한 결과 산림/초지 > 밭 >> 도심/대지 >> 논 > 과수의 순로 분석 대상유역 중 10.7%를 차지하고 있는 농경지에서 유실되는 토양의 추정량은 41.3%이였으며, 이중 6.2%면적을 차지하는 밭이 40.6%으로 44.2%의 산림/초지와 비슷한 수준이었다. 한강상류지역 토양유실 위험성 평가시 분포형 토양침식지도와 항공사진을 비교한 결과 토양유실에 대한 공간인 정보를 확실하게 보여주고 있으며, 토양침식위험성은 남한강권역의 남한강 상류 (1001), 평창강 (1002), 충주댐 (1003) 권역에서 각각 토양침식위험성이 “보통”이상으로 높은 지역이 각각 8.7%, 7.9%, 7.8%로 평균인 5.9%보다 높았으며, 이에 대한 보전방안이 강구될 필요가 있고 판단된다. This study was conducted to evaluate soil erosion risk with a standard unit watershed in the upper Han river basin using the spatial soil erosion map according to the change of landuse. The study area is 14,577 ㎢, which consists of 10 subbasins, 107 standard unit watersheds. Total annual soil loss and soil loss per area estimated were 895 × 10<SUP>4</SUP> Mg yr<SUP>-1</SUP> and 6.1 Mg ha<SUP>-1</SUP> yr<SUP>-1</SUP>, respectively. A result of analysis with a subbasin as a unit showed that annual soil losses and soil loss per area in Namhan river basins was more than in Bukhan river ones. Predicted annual soil loss according to the landuse ranked as Forest & Grassland > Upland >> Urban & Fallow area > Paddy field > Orchard. Upland area covered 6.2% of the study area, but the contribution of total annul soil loss was 40.6% and that of Forest & Grassland was 44.2%. As a evaluation of soil erosion risk using the spatial soil erosion map, we could precisely conformed the potential hazardous region of soil erosion in each unit watersheds. The ratio of regions, graded as higher “Moderate” for annual soil loss, were respectively 8.7%, 7.9% and 7.8% in 1001, 1002 and 1003 subbasins in Namhan river basin. Most landuse of these area was upland, and these area is necessary to establish soil conservation practices to reduce soil erosion based on the field observation.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
