특수건강진단에 대한 근로자들의 태도에 영향을 미치는 요인들을 조사하기 위해 대구지역의 29개 사업장에서 특수건강진단 수검근로자들에게 자기기입식 설문조사를 실시하여 그중 779명을 대상으로 하여 분석하였다. 건강믿음모형을 일부 변형하여, 특수건강진단에의 자발적 수검 여부와 필요성 인지를 최종적인 종속변수로 한 새로운 연구모형을 만들어서 이들에 영향을 미치는 요인들을 분석하였다. 특수건강진단에 대한 필요성 인지율은 77.2%, 자발적 수검율은 79.2%로 나타났다. 자발적 수검 여부에는 특수건강진단에 대한 필요성 인지, 유익성, 행동계기가 주요 영향요인으로 제시되었으며, 특수건강진단에 대한 필요성 인지에는 직업병에 대한 감수성 및 심각성, 특수건강진단에 대한 지식, 회사의 지지도가 통계적으로 유의한 영향을 미쳤다. 직업병에 대한 감수성 및 심각성에는 성, 연령, 학력, 직업경력, 보건교육경험이, 특수건강진단에 대한 지식에는 연령, 학력, 직업경력, 질병통제위가, 특수건강진단에 대한 유익성에는 연령, 질병통제위, 건강자부심, 보건교육경험이 유의한 영향을 미치는 변수로 나타났다. 이러한 결과로 미루어 볼 때 특수건강진단에 대한 자발적 수검률과 필요성 인지율을 높이기 위해서는, 직업병 판정을 받은 사업장에서는 그 사실을 널리 알려 직업병에 대한 경각심을 높여야 하며, 특수건강진단의 결과를 근로자 본인에게 바로 통보하여야 하고, 회사의 적극성을 높이기 위해 회사간부 대상의 홍보 및 교육 프로그램이 필요할 것으로 생각된다. 보건교육 경험이 특수건강진단에 대한 지식과 유익성, 직업병에 대한 감수성 및 심각성에 영향을 미치는 것으로 보아, 앞으로의 보건교육은 여성, 저연령, 저학력, 저경력자 위주로 이루어져야 하고, 교육 실시 횟수를 늘이고 직업관련 내용을 더 많이 포함하여야 할 것으로 생각된다. 더불어 특수건강진단의 결과로 인해 근로자 본인에게 불이익이 돌아가지 않도록 배려되어야 할 것이다. To investigate the factors influencing workers' perception and attitude toward special periodic health screening test for workers, a survey with self-administered questionnaires was performed on 779 workers who had special periodic health screening test from September 1 to October 15, 1994. A study model was developed by modifying the health belief model. The end and intermediate response variables of the model were the voluntary participation and necessity perception on the special screening for workers. The result of analysis was consistent with the study model. Rates for the necessity perception and voluntary participation on the special screening for workers were 77.2%, 79.2%, respectively. Factors influencing on the voluntary participation were necessity perception, benefit of special screening for workers, and cue to action. And on the necessity perception were susceptibility and severity to occupational disease, knowledge to special screening for workers, and support of company. General and occupational characteristics influencing on the susceptibility and severity to occupational disease were sex, age, educational level, work duration, and health education. On the knowledge to special screening for workers were age, educational level, work duration, and locus-of-control. On the benefit of special screening for workers were age, locus-of-control, pride on health, and health education. Therefore, to increase the voluntary participation and necessity perception on the special periodic health screening for workers, 1) if a worker is judged as occupational disease, the judgment should be widely known in his workplace, 2) the screening result forms should be directly sent to the workers themselves, 3) for the positivity of employers, the campaign and education program subjected to them should be planned, 4) health education should give the first consideration to the younger, lower educational level, and newly employed women, and its frequency should be increased and it should be more frequently dealt with occupation-related subjects, and 5) the employers should have a careful concern in not being disadvantageous to workers due to result of screening.

남시현,채석래,차영주 중앙대학교 의과대학 의과학연구소 2000 中央醫大誌 Vol.25 No.1

Leukocyte differential counting and flags performed by hematoma autoanalyzer(Sysmex SE-9000) were evaluated in 726 specimens and compared with manual leukocyte differential counting. The results were as follows. 1. The correlation cofficient between the leukocyte proportion of automated and manual differential counting was 0.970,0.986,0.667,0.927 and 0.379 for neutrophil, lymphocyte, eosinophil, and basophil, respectively. In 100 healthy blood there were no significant differences between the results of automated and manual differential counting expect basophil. 2. One or more flags were pronted out in 480 specimens in which 217(45.2%) "Left shift", 142(29.6%) "Aty/Abn lympho", 138(28.8%) "Immature Gran", 109(22.7%) "Blasts" and 81(16.9%) "NRBC" could be observed. 3. Almost all of the false negative cases, for examples, 18 of 22 "Left shift", 10 of 11 "NRBC", and all 9 "Immature Gran" and 2 "Aty/Abn Lympho" have another kind of one or more flags instead, and were not regarded as false negative because they could be reviewed by another way. 4. False negative rate, false positive rate, negative predictive value, positive predicitive value, sensitivity, specificity and efficiency was 0.7%,22.4%,98.2%,64.4%,98.4%,61.7% and 76.9% respectively for the WBC suspect flags. In conclusion, the differential counting ability of Sysmex SE-9000 was acceptable for detecting abnormal or immature cells, and considered to be very useful for screening test.

Objectives : This study was carried out to understand the prevalence and risk factors of green tobacco sickness (GTS) among Korean tobacco harvesters. Methods : The authors conducted a questionnaire among the tobacco harvesters (1,064 persons from 555 out of 723 tobacco harvesting households) in Cheongsong-gun for 4 days from May 7 to 10, 2002. Results : The study subjects were 550 males and 514 females. The recognition and experience of GTS up until 2001 were 96.4% and 61.9%, respectively. The prevalence of GTS in 2001 was 42.5%, and was significantly higher in females than in males (59.0% vs. 26.6%, p<0.01). The incidence density of GTS according to the number of workdays in 2001 was 12.3 spells/100 person..days. The GTS symptoms reported by the tobacco harvesters in 2001 were dizziness in 441 cases (97.6%), nausea in 414 (91.6%), headache in 349 (77.2%) and vomiting in 343 (75.9%). The use of gloves, hat and wristlets, sweating at work and the number of working hours significantly increased the prevalence of GTS (p<0.05). Multiple logistic re- gression analysis was used to determine the factors significantly associated with GTS. Odds ratios for smoking, working over 10 hours and sweating at work were 0.26 (95% CI:0.19-0.35), 1.64 (95% CI:1.26-2.14) and 1.60 (95% CI:1.14-2.25), respectively. Of those who reported GTS in 2001, 311 cases (68.8%) underwent treatment from their local medical facilities. Conclusions : In Korea, there are many tobacco-harvesting households, and most may be stricken with GTS. More extensive epidemiological studies, including the incidence and associated risk factors, are expected and a surveillance system including measurements of cotinine in urine should be conducted.

The increase of health care expenditures is an important problem in the almost countries. Also, suppression of the health care expenditures is an important problem in the health field of Korea since the national health insurance for total people in 1989. Thus, it is very important to grasp the change of the health care expenditures of family and proportions of the health care expenditures to total expenditures of family, because they are the basis of national health care expenditures in Korea. While the health care expenditures of urban family were increased during 1980-1993 by 12.8% annually, the total expenditures of urban family were increased by 14.8% annually. Consequently, the proportions of health care expenditures to total expenditures were decreased from 5.98% to 4.76%. The proportions of health care expenditure for 3 years to come were predicted to 4.75% in 1994, 4.67% in 1995, and 4.63% in 1996 by the time-series analysis. That is, it was predicted that they would be decreasing slowly. The product elasticity of health care expenditure was less than 1 in the multiple regression analysis. so the health care is normal good rather than superior good. Therefore, it seems that the household economy is able to bear the expense pursuing the improvement of quality of health care by actualizing the medical insurance fee.

최근 인구 고령화로 인해 허혈성 심장질환, 허혈성 뇌졸중, 말초 동맥 질환 등의 허혈성 혈관질환의 유병률이 지속적으로 증가하고 있다. 허혈성 질환에 대한 현재 표준화된 치료법은 약물 요법 및 수술을 통한 재관류요법이다. 재관류요법은 손상된 동맥의 기능을 회복시킬 수 있지만 허혈로 인해 손상된 주변 조직의 기능 회복에 있어 효율적이지 않다. 그러므로 허혈 질병을 안전하고 효과적으로 치료하고 주변 조직의 기능을 회복시킬 수 있는 새로운 치료전략의 개발이 필요하다. 이러한 한계를 극복하기 위해 손상된 부위를 재생하는 줄기세포 기반 치료가 허혈성 혈관질환의 유망한 전략으로 연구되어 왔다. 다양한 조직에서 분리할 수 있는 중간엽줄기세포(MSC)는 면역 조절, 혈관 신생 촉진 및 다양한 관련 인자의 분비를 통해 손상된 조직을 재생함으로써 허혈성 질환의 치료에 유망한 것으로 나타났다. 또한, 줄기세포 치료 효과를 높이기 위해 3D 배양법을 이용하거나 세포 프라이밍(Cell Priming)과 같은 MSC 기능을 강화하여 이식 효율을 높이는 새로운 접근법이 연구되고 있다. 이 논문에서는 MSC를 허혈성 질환 치료에 사용하는 다양한 전략을 제공하고 허혈성 부위에서 MSC의 분화(Differentiation), 증식(Proliferation) 및 생착(Engraftment)과 같은 이식의 문제에 대해 논의한다.

Objectives : To investigate the therapeutic compliance and its related factors in lung cancer patients. Methods : The subjects of this study comprised 277 patients first diagnosed with lung cancer at Kyungpook National University Hospital between Jan 1999 and Sept 1999. Of these, 141(50.9%) participated in the study by properly replying to structured questionnaires. The data was analyzed using a simplified Health Decision Model. This model includes categories of variables covering therapeutic compliance, health beliefs, patient preferences, knowledge and experience, social interaction, sociodemographic and clinical characteristics. Results : The therapeutic compliance rate of the 141 study subjects was 78.0%. An analysis of health beliefs and patient preferences revealed health concern (p<0.05), dependency on medicine (p<0.05), perceived susceptibility and severity (p<0.05) as well as preferred treatment (p<0.01) as factors related to therapeutic compliance. Factors from the sociodemographic characteristics and clinical factors that were related to therapeutic compliance were age (p<0.01), monthly income (p<0.05), histological type (p<0.05) and clinical stage (p<0.05) of cancer. Conclusions : In order to improve therapeutic compliance in lung cancer patients it is necessary to educate the aged, low-income patients, or patients who have small cell lung cancer or lune cancer of an advanced stage for which surgery is not indicated. Additionally, it is essential for medical personnel to have a deep concern about patients who have poor lifestyles, a low dependency on medicine, or a high perceived susceptibility and severity. Practically, early diagnosis of lung cancer and thoughtful considerations of low-income patients are important. By means of population-based education in a community, we may promote attention to health and enhance the early diagnosis of lung cancer.

신경행동평가의 단순 반응시간 검사에 시각 자극횟수 및 방법이 미치는 영향

컴퓨터를 이용한 단순반응시간 검사의 적정한 자극횟수를 정하고, 자극방법에 따른 단순반응시간의 차이를 보고자 교육수준과 연령이 동일한 층의 의과대학생들 240명을 대상으로 단순반응시간검사를 수행하였다. 적정자극횟수를 정하기 위해 120명에 대해 96회의 단순반응시간 검사를 수행하였다. 기존검사 및 연구에서 수행된 횟수를 포함하여 12회, 16회, 24회, 36회, 44회, 48회, 60회, 64회, 72회, 84회, 96회에 대해 평균과 표준오차 및 각각의 표준오차를 구하고 각각의 횟수에 대해 상관계수를 구하였다. 모든 횟수에서 남자 98명과 여자 22명간에 평균단순 반응시간은 통계적으로 유의한 차이를 보였으나(P<0.05), 표준편차는 차이를 보이지 않았다. 44회 이상부터는 비교적 안정된 값을 보였으며 남녀별로 비교적 안정된 값을 보인 횟수인 60회, 64회를 중심으로 상관분석 결과를 본 결과, 64회를 가장 적정한 자극횟수로 정하였다. 적정자극횟수로 선정한 64회로써 자극방법을 달리하여 검사한 후 상관분석한 결과에서도 자극횟수 64회의 적정성을 확인하였다. 자극방법에 따른 차이를 보기 위해서 또다른 120명에게 5x5cm의 적색사각형을 자극으로 준 단순반응시간 결과를 직경 2cm의 흰색원을 자극으로 주었던 앞서의 결과와 비교하였다. 적색 및 흰색 자극에 대해 각각 253.46 ±28.55msec, 269.31±26.90msec로서 통계적으로 유의한 차이를 보였다(p<0.01). 남녀별로도 동일한 결과를 보였다. 그러나, 표준편차에 대해서는 두군간, 남녀간 차이를 보이지 않았다. 컴퓨터를 이용한 검사에서 중요한 문제중의 하나인 동기유발방법에 따른 영향을 보고자 매 검사시행결과를 화면에 보여준 군과 보여주지 않은 군의 단순반응시간 검사결과를 비교하였다. 두군의 평균 단순반응시간은 각각 252.74±29.42 msec, 252.20±26.66 msec 로서 유의한 차이를 보이지는 않았으나 매시행 결과를 화면에 보여준 군에서 좀더 빠른 단순반응시간을 나타내었다. 표준편차에 대해서도 유의한 차이를 보이지 않았다. 따라서, 상이한 방법으로 수행된 신경행동검사결과의 비교시에는 자극방법에 따른 영향을 고려하여야 할 것이며 검사자의 동기유발을 위해 노력하여야할 것이다. In order to evaluate the effects of number and method of visual stimuli on simple reaction time and determine the proper number of trials, simple reaction time of the computerized test of NTOS(Neurobehavioral Test for Occupational Screening) was carried out on 240 medical students. The prominent difference was found between male and female on simple reaction time. Regarding the effect of number based on the parameters of measured and the purpose of test itself, 64 trials was considered as proper number. The mean reaction time was different according to the methods of visual stimuli, such as color and size(p<0.05). The larger and more intence visual stimuli were, the faster simple reaction time was. In respect to sex, that difference was similar. But, there was no difference depending upon whether the each result of each trial was showed on the monitor. The subjects, however, showed much interest when the result showed. Further studies, including the various variables on visual stimuli, are required to compare among various studies.
