한국 양계의 성장기이었던 1971년부터 1988년까지 최근 18연간 국내 양계농가로부터 농촌진흥청 가축위생연구소에 의뢰된 닭 가검물의 병성감정결과 질병검색된 총 9,012건 중 전염성 질병으로 진단된 6,181건에 대하여 검색 연도별, 계절별 및 일영별 검색상황을 조사 분석하였던 바 다음과 같은 결과를 얻었다. 1. 연도별 전염성 질병의 검색률은 49.3％(1973연)∼78.3％(1985년)로써 연평균 68.6％로 나타나 비전염성 질병(31.42％)보다는 월등히 높았다. 2. 전염성 질병 중에는 세균성이 32.6％(16.2∼42.5％)로 가장 높았고 다음 바이러스성 질병이 26.3％(21.8∼38.1％)이었으며 기생충성 및 곰팡이성 질병은 각각 7.7％ 및 2.1％의 낮은 검색율을 나타내었다. 3. 세균성 질병으로는 마이코프라스마병, 대장균증 및 포도상구균증의 연평균검색률이 각각 8.8％, 8.5％, 5.8％로 가장 높았으며, 다음 살모넬라균증, 추백리, 난황염 및 수란괌염이 각각 0.8∼1.5％ 이었고 피부염(0.2％) 및 연쇄상구균증(0.1％)은 매우 낮은 빈도로 검색되었다. 4. 바이러스성 질병중에는 임파성 백혈병 및 마렉병이 각각 연평균 7.5％ 및 7.2％로 가장 많았고 다음 뉴캣슬병(4.4％), 전염성 후두기관염(2.0％), 전염성 낭병(1. 7％) 및 조뇌척수염(1.0％)의 순이었으며 그 외 전염성 기관지염, 산란저하증 '76 및 봉입체간염 등이 각각 1.0％, 미만으로 검색되었다. 5. 기생충성 질병의 검색률에 있어서는 닭 콕시듐병이 연평균 4.5％로 가장 높았고 다음 회염증이 1.4％이었다. 그 외에 류코싸이토준병 흑두병, 맹장충증 및 외부기생충증이 각각 0.2∼0.7％의 낮은 비율로 검색되었다. 곰팡이성 질병으로는 곰팡이성 폐렴이 연평균 2.0％, 다음으로 캔디다증이 0.1％ 검색되었다. 6. 계절별 전염성 질병의 검색은 하계 및 추계절에 각각 27.7％ 검색되어 가장 높았으며 다음 동계(23.5％) 및 춘계절의 순으로 낮았다. 이들중 세균성, 바이러스성 및 곰팡이성 질병은 이와 유사한 경향이었으나 기생충성 질병은 하계 및 추계절에서의 검색률이 각각 34.3％ 및 39.5％로 다른 계절에 비하여 월등히 높았다. 7. 세균성 포도장구균증은 추계절에서의 검색율이 가장 높았으며, 바이러스성 질병으로는 마렉병, 전염성 후두기관염 및 전염성 낭병은 하계절에, 그리고 임파성백혈병, 계두 및 산란저하증 '76은 추계절에서 가장 높았으며 전염성 기관지염은 동계절에 최고빈도로 검색되었다. 기생충성 질병에 있어서는 콕시듐병을 위시하여 회충증, 류코싸이토준병 및 흑두병등 대부분의 주요질병이 하계절 및 추계절에 가장 많이 검색되었다. 8. 닭 일영별 전염성 질병의 검색률은 육성계(30∼150일영)에서 47.4％의 가장 높은 검색률을 나타내었고 다음 성계(150일영이상)에서 35.3％ 및 유추(30 일영미만)에서 17.3％의 순이었다. 이중 세균성 및 기생충성 질병은 육성계에서의 검색률이 가장 높았으나, 바이러스성 질병은 육성계 및 성계에서 거의 같은 비율로 높았으며 곰팡이성 질병은 유추에서 가장 높은 검색률을 나타내었다.
According as the automation of clerical work(OA ; Office Automation) develops, the use of VDT(Visual or Video Display Terminal) is increasing suddenly. But, in proportion to the spread of office automation(OA tendency), the self-conciousness syptom attendant upon the work is appearing also (Kim, Jung Tae, Lee, Young Ook, 1990). The apparatuses of office enable the clerical workers to be convenient and perform mass businesses. But, they are increasing the opportunity to be exposed to VDT syndrom, techno stress, computer terminal disease, pain by muscle strain(RSI), bradycausia of noise nature, and electromagnetic waves, etc. which are referred to as the new type of occupational diseases to the workers. It is the real situation that the workers to use VDT is complaining of the physical inconvenience sense in the recent newspaper and literature, it is the point of time that the sydrome to come from VDT use and computer terminal disease, etc. must be classified into the occupational disease(Lee, Kwang Young 1990, Lee, Kyoo Hak 1990, Lee, Won Ho 1991, Lee, Si Young 1991, Lee, Joon 1991, Choi, Young Tae 1991, Heo, Seung Ho 1989). In addition, it is the real situation that the scientifitic study result about the scope that electromagnetic waves has influence on the human body has not been suggested yet, and criticism on the stable exposure permission standard about electromagnetic waves to be emitted from VDT and on the problem in the health about electromagnetic waves is continuing. (IEEE Spectrum, 1990). In addition according to the experience of nursery business of industry field, it is the real situation that the patients who consult complaining of physical and mental inconvenience sence, among the users of apparatus of office automation, are reaching 10% of the patients coming to doctor's room. Therefore, it is necessary to confirm the self-consciousness symptom that the clerical workers complain of multilaterally with the actual state examination about the use of the apparatuses of offices automaton. Thus, this study was tried as th basic data for the cosultation and education for the maintenance and furtherance of the health of workers as the nurse of industry field, by confirming the contents of self-consciousness symptom attendant upon the use of the apparatus for office outomation making the financial institution in which the spparatus for office automation in most frequently used as the subject, and by examining whether there is the difference according to the subject of study, the data were collected, by using the questionnaire method, making 200 workers who consented to the study participation as the subject, among the persons who have spent over 3 months since they used the apparatuses for office automation and didn't receive the treatment in hospital due to the clerical disease for recent 3 years. The period of data collection was from Oct. 9, 1991 to Oct. 12. As for the measurement instrument about the complaint if self-consciousness symptom attendant upon the use of apparatuses fo office automation, the question item on the complaint symptom of health problem attendant upon the treatment of VDT that Kim(1991) developed and on CMI health problem and the question items on the fatigue degree due to industry were used by previous examination to 25 persons. Collected data were analyzed with the statistical method such as percentage, arithmetic mean, Person correlation coeffient, Kai square verfication, t-test, ANOVA, etc. by using SPSS/PC+ program, and the result is as follows : 1. The self-consciousness symptom that the clerical workers complained of most frequetly appeared high in 'My eyes are tired'(99.4%), 'I feel fatigue and weariness'(99.4%), 'I feel that my head is heavy5(90.0%), 'eyesight fell'(88.8%), 'I have a stiff neck'(88.8%), 'I fell pain in the shoulder'(85.0%), 'I feel cold and painful in the eyes'(76.9%), 'I feel the dry sense of eyeball'(76.2%), 'My nerves are edgy, and I an fretful, (75.6%), 'I feel pain in the waist'(73.2%) and 'I fell pain in the back'(72.8%). It emerged that the subject use the apparatuses for office automation complained of self-consciousness symptoms related to visual symptoms and musculoskeletal symptoms. 2. As for the general feature of examination subjects, the result to see the distribution by classifying into sex, age, school career, use career of apparatuses for office automation, skillfulness degree of the use of apparatus for office automation, use hours of the apparatuses for office automation per 1 day, type of business of the apparatus for office automation, rest hours during the use of apparatus for office automation, satifaction degree of business of office automation, and work circumstance, etc. emerged as follows : As for the sex of subjects, the distribution showed that men were 58.8% and women were 41.3%, Age was average 26.9. As the distribution of school career, the distribution showed that4below the graduation of high school' was 58.8%, 'graduation from junior college-university' was 35.0%, and 'over graduate school' was 6.3%. In the question to ask the existence or non-existence of experience of health consultation in connection with the work of office automation, the response that I had the consultation exprience and I feel the necessity emergerd as 90.1% And, the case that the subject who didn't wear the glasses or lens before using the OA apparatus wear glasses or lens after using OA apparatus emerged as 28.3% of whole. As for the existence or non-existence of use career of OA apparatus, the case under 3 years was highest as 52. 7%. As for the skillfulnness degree about the use of apparatus for office automation, most of them are skillful with the fact that 'common' was 44.4%, 'skill' was 42.5%, and 'unskillful' was 13.1% As for the use average hours of the apparatus for office automation per 1 day, the distribution showed that the case under 3-6 hours was 33.1%, the case under 6-9 hours was 28.1%, the case under 3 hours was 30.6%, and the case over 9 hours was 8.1% Main OA business and the use hours for 1 day showed in the order of keeping and retrieval, business of information transmission(162min), business of information transmission(79.3 min), business of document framing(55.5 min), and business of duplication and printing(25.4min). as for the rest during the use of apparatus for affice automation, that I take rest occasion demands the major portion, but that I take after completing the work emerged as 33.8%. Though the subiness gets to be convenient by the use of the apparatus for of office automation, respondents who showed the dissatisfaction about the present OA business emergd high as 78.1%. The work circumstances of each office was good with the fact that the temperature of office was 21.8, noise was average 42.7db, and the illumination was average 364.4 lx, in the light of ANSi/HFS 100 Standard. 3. Sight syptom, musculoskeletal symptom, skin and other symptoms showed the significant difference according to the extent of skillfulness of the apparatus for office automation. All the symptoms exept skin symptom showed the difference according to the use hours of the apparatus for office automation. All the question items exept the sytoms of digestive organs and the rest hours during the apparatus for office automation showed the signicant difference. The question item which showed the signicant difference from the satisfaction degree of present OA business showed the significant difference from all the question item classified into 6 groups. But, age and school career didn't significant difference from the complaint of any self-consciousness symptoms.
