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.

Background and Objectives : Cigarette smoking is a major factor and the most modifiable risk factor for atherosclerosis. Endothelial dysfunction is an early event in atherosclerosis, before the structural change of the systemic arteries. We hypothesized that endothelial dysfunction might be present in the systemic arteries of young adult smokers and that this might be dose-dependent phenomenon. Therefore, we try to certify that smoking is associated with endothelial dysfunction in healthy young adults without other risk factor of atherosclerosis. Subjects and Methods : we studied noninvasively 29 subjects aged 3 to 4 decades without other risk factor of atherosclerosis, they were composed of the two groups, current smokers(n=15) and nonsmokers(n=14). Smoking history varied from 3 to 20 pack years. Using high-resolution ultrasound, vessel diameter and mean flow rate were measured at rest, during reactive hyperemia(with flow-mediated endothelium-dependent dilation), and after sublingual nitroglycerin(NG-induced endothelium-independent vasodilation). Result : Flow mediated endothelium dependent dilation was observed in the control subjects (9.4±3.44%) but was impaired in the smokers(5.8±2.51%)(p=0.004). NG-induced endothelium independent dilation is no difference in all subjects. Conclusion : Cigarette smoking is associated with endothelial dysfunction in healthy young adults.

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.

새로운 저비용 고효율 조류 피해 방지법의 개발을 위한 기초자료를 얻기 위하여, 현재 사과, 배 과수원에서 사용되고 있는 조류피해 방지 방법들의 정확한 효과를 서로 비교 검토하고, 아울러 충북지역 과수 재배 농가들을 대상으로 유해조류에 의한 피해 실태와 경제성 있는 조류 피해방지 방법에 대한 설문조사를 병행 실시한 결과는 다음과 같다. 1. 조류피해는 방조망 설치에 의해서만 완전히 방지할 수 있었으며, 조류 피해율별 손익계산 결과를 참고하여 이익이 있을 때는 표준방조망을 설치하고, 그렇지 않을 경우에는 설치비가 저렴하며 농가에서 간단히 시공할 수 있는 간이방조망 설치가 더 경제적인 것으로 판단되었다. 도내 과수 농가의 조류피해는 지역 간에 큰 차이가 있었으며, 음향적 방제인 버드가드와 보호봉지인 망사봉지에 의한 방제가 가장 효과적이었다. 그러나 버드가드는 높은 설치비용이 문제되므로, 퇴치 효과가 비슷하거나 더 우수하면서 저렴한 한국식 음향 기구를 개발할 필요가 있는 것으로 판단되었다. 보호봉지인 UV 봉지와 플라스틱 보호캡 및 망사봉지 처리는 품종에 관계없이 피해를 현저하게 감소시켰으나, 과실의 착색 등 품질에 미치는 영향에 대해서 추가적인 연구와 검토가 필요한 것으로 생각되었다. To obtain basic data for low cost-high efficiency control methods for bird damage, the available control methods currently in use mostly in Chungbuk Province were tested on site, and the control efficiency was compared. Also, a comprehensive survey of actual bird damage and the control methods on model apple and pear growers in Chungbuk Province was conducted. The results are summarized as follows. The perfect control for bird damage was possible only through bird net, it was recommended that profit-and loss account must be considered before installing bird net, and when the 'standard bird net' does not come up to break-even point, more economic and convenient 'simplified bird net' should be a alternative. Actual extent of bird damage varied according to the locality, and imported acoustic apparatus BirdGard^R, development of our own system with superior or same quality and reasonable price is necessary. Fruit bags such as UV bags, plastic protective caps, and net bags were highly effective for bird damage control, irrespective of fruit species and cultivar, but further study to resolve some problems such as poor coloration caused by bagging is necessary.

The microsensors to detect NH3 gas were fabricated by continous deposition of In film by evaporation and ZnO film by rf magnetron sputtering onto the Si3N4 diaphragm that was prepared by MEMS technology. The sensors were heat-treated to dope In into the ZnO thin film. The electrical characteristics of sensitive films were studied as a function of heat-temperature by 4-point probing method and electrometer. The dependence of the sensitivity, selectivity and time response of sensor on heat-treatment temperature was investigated. The microsensor heat-treated at 400℃ that 3000 A ZnO:In film was chosen as gas sensitive film, showed the highest sensitivity 23% at 350ppm NH3 under 366mW heater power. The time response was 90sec. The sensitivity for CO and NOx was not observed.

"Dice와 fill" 방식을 이용한 1-3 압전복합재의 제조와 횡방향 단위 크기에 따른 압전특성 평가

김영덕,김광일,정우철,김흥락,김동수 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.4

NDT나 의료용 영상장치에 응용되는 압전복합체는 일반적인 세라믹이나 고분자 압전재료에 비하여 많은 장점을 가진다. 이들 응용분야에서는 전기기계결합게수가 높아야 하고, 음향임피던스가 낮아야 한다. 그러나, 압전복합제의 횡방향 단위 크기가 조밀하지 못한 경우 횡방향으로 전행하는 판파에 의한 불필요한 진동이 표면에 발생하게 된다. 횡방향 단위 크기와 세라믹 체적비에 따른 압전 특성을 조사하기 위하여 PMN-PZT 세라믹과 Epofix 에폭시로 에폭시의 폭을 달리하면서 1-3 형 압전복합체를 제작하였다. 제작된 1-3형 압전복합체의 두께방향 진동모드의 전기기계결합계수, 음향임피던스는 각각 0.36~0.64, 9.8~22.7 MRayl로 나타났으며, 횡방향 단위크기가 줄어들수록 횡방향 모드 공진 주파수가 증가하였다. The piezoelectric composites had many adventages in comparison qith conventional piezoelectric ceramics and piezopolymers for ultrasonic transducers used in NDT and in medical ultrasonic imaging. The electromechanical coupling coeffucient should be high and the acoustic impedance should be low in these applications. However, the cross-coupling with spurious oscillations caused lateral spatial scale. The thickness mode electomechanical coupling coefficient of 1-3 type of piezoelectric composites were 0.36 to 0.64, and the acoustic impedance of them were 9.8 to 22.7 MRayl. The lateral resonance frequency of 1-3 type piezoelectric composites shifted to high frequency region with decreasing lateral spatial scale.
