The big trees have been keeping the relation to human's living way in various aspects, environment protection, emotion creation and tree worshiping through which they believed to be safe, happy and prosperous, and also giving more recreational opportunity to provincial particularly. This study was carried out to analyse the status of designation and management of big tree in Iri-Iksan province, Chollabuk-Do. The result are summarized as follows. 1. It was appeared that at present Big trees in the investigated area were 78 location (7 families, 9 genera, 11 species) that was identified. Among them the species appearing most frequently were Zelkova serrata(25), Salix glandulosa (20), Gingko biloba(15) and Celtis japonica(8) in that order. The order hand, designation grade of big tree classified into six categories, that is 1 botanic natural monument, 5 Si-Kun tree, 3 Eup-Myon tree, 1 maeul tree, 53 Restraint tree ad 15 Non-Designation tree. 2. In designation of nurse tree, there are key needs that are professionals in field survey. We suggested the futher designation plan stressed the importance of the value of big tree. 3. Government have to increase of the forestry staff who take sole charge of the protection of big tree, and must reach managers the technique for effective management of big tree. 4. We have to make an budget of big tree management, establish a protective facilities, control of insets and disease on time, and treat and operate on the injured big tree. Thus government should be positively concerned, and more research would need to understand the critical factors affecting the big tree.

정수영,강성규,김대성,이세훈 大韓産業醫學會 2004 대한직업환경의학회지 Vol.16 No.2

목적 : 고농도의 톨루엔에 노출될 가능성이 있는 그라비아 인쇄 사업장 5개소를 전정하여 톨루엔 노출 수준과 신경행동학적 기능을 평가하였다. 방법 : 톨루엔의 노출수준을 평가하기 위하여 기중 톨루엔 농도와 요중 마뇨산 농도를 측정하였고 신경행동학적 기능을 평가하기 위하여 컴퓨터 신경행동검사(BARS-K)를 실시하여 147명의 비노출군과 비교하였다. 신경행동검사는 숫자외우기(정순, 역순), 단순반응시간, 손가락 두드리기(우수, 열수), 부호 숫자 짝짓기, 선택주의력(맞은수)에 대해 시행하였다. 결과 : 연구결과는 다음과 같다. 1. 5개 사업장을 대상으로 측정한 기중 톨루엔의 평균 노출수준은 56.7(GSD60.9) ppm 이었고 사업장별 기중 톨루엔 평균농도는 10.5(GSD5.9)~181.9(GSD17.7)ppm로서 사업장에 따라 차이가 있었으며, 100 ppm을 초과하여 노출된 근로자수는 10명이었다. 2. 5개 사업장을 대상으로 측정한 요중 마뇨산의 평균 농도는 1.87(GSD2.06) g/g creatinine 이었고 사업장별 요중 마뇨산 평균농도는 0.31(GSD0.11)~5.14(GSD0.55) g/g creatinine 으로 나타났으며 노동부에서 제시한 요중 마뇨산의 노출한계인 2.5 g/g creatinine를 초과한 근로자수는 14명이었다. 3. 기중 톨루엔 농도와 요중 마뇨산 농도의 상관관계는 r=0.899(p<0.01)로서 유의한 상관성이 있는 것으로 나타났다. 4. 신경행동검사(BARS-K)의 각 검사항목에 대하여 혼란변수의 영향을 통제한 후에도 숫자외우기(정순), 두드리기(우수, 열수), 선택주의력(맞은수) 검사에서 톨루엔 노출군과 비노출군 사이에 통계적으로 유의한 차이를 보였다. 5. 노출군만을 대상으로 연령, 교육정도, 근무기간, 컴퓨터친숙도, 음주 등의 혼란변수를 통제하였을 때 숫자외우기(역순) 검사만이 톨루엔 노출수준에 따라 유의하게 저하되는 검사항목이었고 두드리기(우수) 검사와 선택주의력(맞은수) 검사는 톨루엔 노출수준보다 연령이나, 음주에 의해 더 많이 영향을 받는 것으로 나타났으며, 나머지 검사항목들의 경우 유의한 영향을 미치는 변수가 없었다. 결론 : 이상의 결과로 그라비아 인쇄 사업장의 근로자는 허용기준 내외의 비교적 높은 농도의 톨루엔에 노출되고 있으며, 톨루엔을 포함하는 유기용제 노출로 인한 신경행동학적 수행능력의 저하를 발견할 수 있었다. Objectives: The aims of this study were to investigate the occupational exposure level to toluene among rotogravure printers and neurobehavioral effects among them. Methods: Fifty rotogravure printers and 147 controls participated in this study. Environmental and biological monitoring was performed for the investigation of toluene expo- sure level, and neurobehavioral performance test were performed by using the Behavioral Assessment and Research System with Korean language instructions(J3ARS-K). Results: The major results were as follows; 1. Geometric mean toluene concentrations in the ambient air of 5 rotogravure printing work- places were 10.5 (GSD 5.9)-1181.9 (GSD 17.7), with a grand total of 56.7 (GSD60.9) ppm. 2. The geometric mean urinary hippuric acid level for rotogravure printers of 5 workplaces were 0.31 (GSD 0.11)-5.14 (GSD 0.55), with the grand total of 1.87 (GSD 2.06) g/g creatinine. 3. There was a linear correlation between hippuric acid levels in urine and the exposed toluene in air: urine hippuric acid (g/g creatinine)=0.03 toluene (ppm) + 0.15 ( ~ 0 . 8 9 9 , ~-4.01, n=50). 4. After adjustment for confounders, significant associations were found between toluene exposure and Digit span forwards, Digit span backwards, Tapping preferred hand, Symbol digit and Selective attention trials. Conclusions: 1. Rotogravure printers were occupationally exposed to relatively high concentration to toluene. and their neurobehavioral performances were decreased. 2. The BARS neurobehavioral testing program, which minimizes the use of text in the instructions, was very effective in overcoming the cultural barriers in neurobehavioral testing.

정인원,박환규,정연복,김수일,원구연,김교형,신철진 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: 정신보건법에 근거하여 매월 정기적으로 개최된 충청북도 정신보건심판위원회를 통하여 정신질환자의 계속입원치료 청구 심사의 현황과 문제점을 파악하고 개선사항을 지적함으로써 정신질환자의 효율적인 관리를 유도하고 인권남용의 여지를 차단하고자 한다. 방 법: 충청북도 내의 정신의료기관에서 계속입원치료 심사청구서 및 진단서, 보호의무자의 동의서 등을 제출한 정신질환자들을 대상으로 계속입원치료 청구에 대한 승인 여부를 매달 정기적으로 심사하였다. 1년 6개월여동안 심사한 자료를 정리하여 진단 및 보호의무자, 의료보장별 특성과 불승인률 등을 분석하였다. 결 과: 충청북도 심판위원회에 계속입원치료를 청구한 정신질환자는 21차례의 위원회 동안 총 7,981명이었으며, 진단별로 정신분열병은 80.9%, 알콜중독은 8.1%, 치매 등 기타는 11.0%이었다. 또한 보호의무자는 시장 또는 군수가 29.8%, 부모가 26.9%, 형제가 26.1%, 부부가 6.3%, 자녀가 5.9%, 기타가 5.0%로 나타났으며, 의료보장은 의료보호가 73.0%, 의료보험이 27.0%이었다. 이들 중에서 196명이 계속입원치료를 불승인받아서 전체 불승인률은 2.46%이었으며 정신분열병과 알콜중독 환자의 진단별 불승인률은 각각 0.73%와 17.6%이었다. 결 론: 정신과 병상의 대부분이 장기적으로 입원하는 만성 정신질환자들로 구성되어 있어서 이들에 대한 별도의 대책이 시급하다. 또한 계속입원치료가 불승인되어 퇴원한 환자들의 재활 및 사회적응을 위한 사회적 지지 체계가 부족하며, 특히 환자의 인권보호를 위한 구체적인 기준 등이 필요하다. Objectives: This study was to develop effective managements and to avoid the abuse of human rights in mentally-ill patients. The Mental Health Judgement Board of Chungchongbuk-do province has been held monthly since August, 1997 according to the Mental Health Act. In this study, the procedures and the problems of judging continuing hospitalization of chronic mentally-ill patients were reviewed. Methods: The mentally-ill patients who submitted the request for continuing hospitalization with the certificate of charged doctor and the agreement of caregiver were reviewed by the Mental Health Judgement Board of Chungchongbuk-do province. The analysis of the diagnoses, caregivers, medical care systems, and rejection rate for the patients were done. Results: Total mumber of mentally-ill patients who requested for continuing hospitalization were 7,981 from twenty-one monthly meetings. The diagnostic distributions were 80.9% for schizophrenic patients, 8.1% for alcoholics and 11.0% for others including dementia. As for the caretakers, the rate of majors was 29.8%, parents 26.9%, sibling 26.1%, spouse 6.3%, offspring 5.9%, and others 5.0%. And 73.0% of the patients were on Medicaid and 27.0% were insured. The patients who got the rejection for continuing hospitalization were 196 at the rate of 2.46%. And the rejection rates of schIzophrenic and alcoholic patients were 0.73% and 17.6%, respectively. Conclusions: New policies for decreasing longterm hospitalization of chronic mentally-ill patients are required. And the social support systems for psychiatric rehabilitation and readjustment are presently insufficient for the already discharged mentally-ill. Moreover, the practical guidelines for human rights of patients remains to be suggested.

정광호,성수원,안규동 가톨릭대학산업의학센타 산업의학연구소 1983 韓國의 産業醫學 Vol.22 No.1

This experiment was carried out to investigate the correlation of accuracy among five kinds of instruments which determined an airborne dust at the various locations of same type work. The results obtained were as follows; 1. Digital dust indicator-P type (DDI-P) instrument for determination of relative concentration was found not having significant variations when it was used without corrective coefficient to the quantitative concentration at the places with a few airborne dust in office and laboratory room. 2. Generally, there were the high correlations between determination values resulted by Digital dust indicator(DDI) and Piezobalance(PB). However, the correlation of two instruments to a filter weighing method was insignificant in the same type work. After determining several times (at least 5 times and over), it was desirable to fix the corrective-coefficient. 3. When the size of the particles of airborne dust was large or its concentration was high in suspended airborne dust, the determination values of High volume air sampler-Respirable(HVS(R)) were 2-4 times higher than that of Low volume air sampler-Respirable(LVS(R)). 4. The emyloyment of corrective coefficient for determination values of DDI and PB was not appropriate to HVS(R) comparing with LVS(R) because of the significant changeable differences. In addition, the determination instruments for relative concentration was not appropriate to using by itself at a manufactruing process. There were also problems about sampling time and evaluation when it was determined the total airborne dust with the open face type holder.
