Objectives : To evaluate the effects of a strengthening exercise program on the physical activity, activities of daily living(ADL), social behavior and functional performance of the elderly in a home for the aged. Methods : We administered a survey questionnaire that consisted of questions to establish general characteristics, health habits and status, physical activity, ADL, and social behavior. Additionally, a physical fitness and functional performance examination was peformed on subjects who were 65 years old or older. Study subjects numbered 33 in the experimental group and 35 in the control group. For intervention, we used a strengthening exercise program of the upper and lower limbs for 12 weeks(5 times/week) using dumbbells and lead-packed weights. Results : After the strengthening exercise program, the scores of physical activity and social behavior were significantly higher than the control group and the before exercise measurements. Moreover, the variables of functional performance were significantly higher than in the control group or the before exercise records. Conclusion : These results Indicate that a strengthening exercise program can improve the score of physical activity, ADL and social behavior, as well as decrease the time(sec) of functional performance of the elderly in a home for the aged.

Objectives : To examine the screening rate of cervical cancer in women and to find out the predictive factors for participation in cervical cancer screening programs within their life-time and within the last two years. Methods : The data was based on self-reported questionnaires from 1,613 women whose ages ranged from 26 to 60 years; this survey was peformed between December 1999 and January 2000. This study analyzed the predictive factors for participation in cervical cancer screening programs within their life-time and within the last two years. A logistic regression analysis was performed in order to derive the significant variables from the predisposing factors(demographic factor, health promotion behavior, reproductive factor), intervention factors(information channel, relation with medical stan, and proximal factors(attitude, social influence, self-efficacy). All analyses were peformed by the PC-SAS 6.12. Results : Our analyses showed that the screening rate for the women who received a cervical cancer screening(Pap smear) more than once within their life-time was 56.1% while those who had received one within the last two years was 34.5%. The significant factors for participation in cervical cancer screening program within their life-time were their income, married age, health promotion score, relation with medical staffs, social influence, and self-efficacy. On the other hand, age, number of pregnancies, menarche age, relation with medical staffs, social influences, and self-efficacy were significant factors for those being screened within the last two years. The predictive power of the logit model within their life-time was 68.8% and that within the last two years was 66.6%. Conclusion : The predictive factors for participation in cervical cancer screening program within their life-time are different from those for within the last two years. and that women's relations with medical staffs and social influences were the critical factors impacting on cervical cancer screening rates.

유기용제와 같은 신경독성 물질에 폭로되지 않은 제조업체 여성 근로자를 대상으로 세계보건기구의 Neurobehavioral core Test Battery(NCTB) 7가지 검사 항목 중 사업장 여건을 고려하여 산타아나 민첩성검사와 목적점 찍기, 숫자 기호화, 단순반응시간, 시각기억 검사 등 5가지 항목을 세계보건기구 표준방법에 따라 실시하여, 신경독성 물질폭로로 인한 신경행동학적인 영향을 평가하기 위한 대조군 자료를 마련하고자 본 연구를 시행하였다. 잘 쓰는 손과 반대편 손의 산타아나 민첩성검사 수행능력은 각각 $45.7{\pm}7.1$ 및 $41.9{\pm}6.4$개, 목적점 찍기는 $191.9{\pm}38.6$개였다. 숫자 기호화와 시각기억검사는 각각 $57.7{\pm}16.0$ 및 $7.8{\pm}1.7$개, 단순반응시간의 평균은 $274.8{\pm}44.6msec$였고 평균 표준편차는 $70.5{\pm}69.0msec$였다. 대부분의 신경행동검사 항목들은 피검자의 연령, 교육수준의 영향을 받는 것으로 나타났다. 산타아나 민첩성검사는 양손 모두에서 피검자의 교육년한에 영향을 받는 것으로 나타났다. 목적점 찍기 검사에서 올바르게 한 것은 피검자의 연령과 교육년한에 영향을 받는 것으로 나타났다. 숫자 기호화는 연령과 교육년한에, 단순반응시간은 교육년한에, 그리고 시각기억검사도 교육년한에 영향을 받는 것으로 나타났다. 전체적으로 볼 때 피검자의 교육수준은 모든 검사항목에서 주요한 영향 변수로 작용하고 있었고 연령은 일부 검사의 영향 변수로 작용하였다. With increased use of neurotoxic agents in manufacturing industries, hazardous effects of neurotoxic agents pose significant problems in protecting health of workers who work in these industries. A normal range of neurobehavioral performance is required to study hazardous effects of neurotoxic agents among workers. However, such reference for Korean population is not available yet. The objective of this study is to estimate a normal range of neurobehavioral test performance of female workers in Korea. Data for neurobehavioral test performance developed by the World Health Organization were obtained from 165 female workers. Study subjects, 140 production workers and 25 clerks, who voluntarily participated in this study were not occupationally exposed to neurotoxic agents. The mean age and the mean education years of them were 32 years and 10.9 years, respectively Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention tests among the Neurobehavioral Core Test Battery(NCTB) were included in the evaluation. Subjects were interviewed by a trained interviewer for their detailed occupational history $Mean({\pm}SD)$ performance of the participants were: $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in the Santa Ana dexterity test of the preferred and non-preferred hands; $45.7{\pm}7.1\;and\;41.9{\pm}6.4$ in correct dot of the pursuit aiming test; $57.7{\pm}16.0$ in the digit symbol test; $274.8{\pm}44.6$ msec in the mean simple reaction time and $70.5{\pm}69.0$ msec in the mean standard deviation of it; and $7.8{\pm}1.7$ in the Benton visual retention test. Most neurobehavioral performance scores were correlated significantly with age and educational level. Educational level was found to be a significant independent variable which was associated with all test scores. Age was significantly associated with scores of pursuit aiming and digit symbol tests.

이병국,장임원,정규철,정치경 가톨릭대학산업의학센타 산업의학연구소 1973 韓國의 産業醫學 Vol.12 No.1

By using Siregnost FD 90 lung function monitor with FD 91 body plethysmogrph, we measured airway resistance (?), thoracic gas volume at end-expiration (TGVe) and ventilatory functions in a group of 101 healthy subjects (72 smokers, 29 nonsmokers) and 173 silicotic subjects (150 smokers, 23 nonsmokers) to evaluate the effects of smoking on them. Data were also analyzed in respect to the changes of ?, TGVe and ventilatory functions according to grades of silicosis classified by X-ray findings, functional impairments of resporation and types of ventilatory function. The results obtained were as follows: 1. Mean values of airway resistance (?), airway conductance (?=1/?) and specific conductance (?=?/TGVe) in nonsmokers were 1.352+0.416cm H₂O/sec, 0.820±0.2791/sec/cm H₂O and 0.259±0.149/sec/cm H₂O in healthy subjects and 1.607±0.566cm H₂O/1/sec, 0.762±0.2851/sec/cm H₂O and 0.239±0.149/sec/cm H₂O in silicotic subjects, respectively. On the other hand, those figures in smokers showed a remarkable increase in ? and remarkable decrease in ? and ?, showing the mean values of 1.757±0.324cm H₂O/1/sec, 0.609±0.160 1/sec/cm H₂O and 0.177 ±0.047 /sec/cm H₂O in healthy subjects and 2.093±0.637 cm H₂O/1/sec, 0.528 ±0.190 1/sec/cm H₂O and 0.160 ±0.063 /sec/cm H₂O in silicotic subjects, respectively. 2. In smokers, mean values of ?, ? and ? before inhalation of cigarette smoke were 1.510 ±0.423 cm H₂O/1/sec, 0.734 ±0.249 1/sec/cm H₂O and 0.208+0.090 /sec/cm H₂O in healthy subjects and 2.347 ±0.559 cm H₂O/1/sec, 0.499 ±0.159 1/sec/cm H₂O and 0.175 ±0.074 /sec/cm H₂O in silicotic subjects, respectively. Those figures were significantly different from those after inhalation of cigarette smoke, showing 1.974 ±0.417 cm H₂O/1/sec. 0.554 ±0.169 1/sec/cm H₂O and 0.165 ±of cigarette smoke, showing 1.974 ±0.417 cm H₂O/1/sec. 0.554 ±0.169 1/sec/cm H₂O and 0.165 ±0.778 /sec/cm H₂O in healthy subjects 2.975 ±0.745 cm H₂O/1/sec, 0.355 ±0.081 1/sec/cm H₂ O and 0.126 ±0.061 1/sec/cm H₂O in silicotic subjects, respectively. 3. Airway resistance increased immediately after inhalation of cigarette smoke and lasted about 40 minutes on an average. 4. In silicotics, average values of one second forced expiratory volume, (one second forced expiratory volume/vital capacity)×100 and maximum ventilatory capacity of cigarette smokers were found to be significantly lower than those of nonsmokers. 5. In both healthy and silicotic subjects, airway resistance and ventilatory functions seemed not to be influenced by the number of cigarettes smoked among those whose smoking habits were less than 20 cigarettes a day. 6. In silicotic subjects, the airway resistance and ventilatory functions seemed to be influenced by duration of smoking habit among those whose smoking habits were between 10 and 40 years. 7. ?, ? and ventilatory functions of smokers in the silicotics decreased distinctly more than those of smokers in the healthy subjects; ? and ? in group of category ? and ?, in group of slight, moderate and advanced functional impairment and in group of combined ventilatory impairment, and vital capaicty, one second forced expiratory volume and maximum ventilatory capacity in group of category S???, in group of moderate and advanced functional impairment, and in group of restrictive and combined ventilatory impairment.
