  • 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.

    . In conclusion, the self-consciousness symptoms of the subjects to use OA apparatus appeared differently, according to sex distiction, skillfull degree of OA apparatus, use hours of OA apparatus, the rest hours during th use of OA apparatus, and the satiafaction degree of persent business. Therefore, it is necessary that the nurse in the inuctry field must recognize to receive the education about the human technological physical condition which is most proper for te use of OA apparatus and about the proper rest method until they get accustomed to the use of OA apparatus. In addition, the simple exercise relax the tention of muscle due to the repetitive simple movement, and the education for the protection of eyesight are necessary.

    • 우리나라에서의 벼 줄무늬잎마름병의 발생, 피해, 기생범위, 전염 및 방제에 관하여 1965년부터, 1974년까지 실시한 연구결과를 다음과 같이 보고한다. 1. 발생 못자리에서 줄무늬잎마름병의 피해는 $1.3-8\%$였고 포장에서는 입도중의 발병주율보다 재생도에서의 발생율이 높았으며 보통기재배보다도 조기재배에서 발병이 많았다. 또 포장에서 발병주의 분포는 대체로 휴반가까이에 많은 경향이었다. 벼 엽기별 피해에서 라병성인 일본계 벼의 경우 못자리 때인 3엽기에서 7엽기까지는 감염되면 $100\%$ 고사하였으며 9엽기에서는 $50\%$, 11엽기는 $20\%$, 13엽기 이후에는 고사주를 볼 수 없었다. 참복기간은 3-7엽기에서는 7-15일이었고 9-15엽기에서는 15-30일이었다. 저항성인 통일벼의 경우 1.5-5엽기 접종구는 비교적 발병이 많았으나 9엽기 이후부터는 현저히 떨어져 15엽기 이후는 발병을 거의 볼 수 없었다. 그리고 감염된 것은 초장이 짧고 등숙율과 임실비율이 떨어지는 경향이었다. 2. 기주범위 기주범위를 구명하기 위하여 작물과 목초 및 잡초 36종을 공시하여 아래와 같이 21종의 기주를 밝혀 내었다. 작물: 벼, 보리, 밀 , 귀리, 라이맥, 조, 옥수수, 기장, 참피 목초: 티모시, 빗살대, 이타리안라이그라스, 패래니 알라이그라스, 죤슨그라스, 슈단그라스 잡초 : 들피, 겨피, 방울피, 잠자리피, 개미피, 바랭이, 민바랭이, 좀바랭이, 방동사니대가리, 강아지풀, 비노리, 참새, 포아풀, 독새풀, 우산대바랭이, 개보리, 겨풀, 쇠풀, 조개풀, 넓은 잎 개수염은 새로운 기주로 밝혀졌다. 3. 충매전염 우리나라의 애멸구화기는 5회였으며 수원에서의 제2회성충 최성기는 6월 20일 경이고 제3회성충 최성기는 7월 30일 경이었다. 진주는 수원보다 제2회성충 최성기가 5-7일 빨랐고 진주에서는 제3회성충 최성기의 발생량이 많은 것이 달랐다. 애멸구 세대별 보독충율은 월동약충이 $10-15\%$였고 제1세대유충은 $9\%$, 제2회성충은 $17\%$, 제2세대유충은 $8\%$, 나머지 화기에서는 약 $10\%$였는데 보독충율은 남부지방보다 높은 경향이었다. 1966년부터 1970년생 사이의 애멸구 보독충율은 해에 따라 다소 차가 있었으며 화기별로는 제2회성충과 제3회성충의 보독충율이 높았다. 분리한 애멸구보독충을 재분리하여 이를 교배하였더니 차대에서는 보독충율이 $90\%$인 애멸구를 얻을 수 있었으며 애멸구충령별로는 3, 4, 5령충의 감염능력이 높았고 애멸구 무독충의 바이러스 재획득율은 평균$7.9\%$였고 여기에서 얻어진 친화성계통이라 할지라고 3회접종시험결과 계속하여 3회까지 벼에 바이러스를 매개하지 않았다. 또 애멸구보독충의 감염최적온도는 $25-30^{\circ}C$였으며, $15^{\circ}C$이하에는 감염이 일어나지 않을때도 있었다. 그리고 애멸구기생봉의 기생율은 6월부터 8월말까지 $5-48\%$였으며 7월 10일경이 $32-48\%$로서 가장 높았다.
