The petroleum refinery industry handles a variety of complex chemical substances and employs a large number of people around the world. According to previous research, diseases caused by exposure to chemicals were quite common among workers in refineries until the 1980s. More recently, it is unusual for oil refinery workers to suffer from these serious diseases. The objective of this study was to identify the occurrence level of general diseases and any differences in lifestyle habits of workers in refineries in Korea compared with the general population. In this study, we used the results of health examinations from 2014 for workers at a large oil refinery in South Korea. In addition, based on the results of KNHANES from 2014 as representative of the population, hypertension, diabetes, anemia, hyperlipidemia, liver function abnormality, and kidney function abnormality were calculated using the standardized incidence rate. Hypertension showed a low result with an SIR of less than 1, but a high result in the case of abnormal liver function. The workers' occurrence rates of hypertension, hyperlipidemia, kidney dysfunction, and anemia were lower than those of ordinary salaried employees. however, their occurrence rate for abnormal liver function was markedly higher. In lifestyle habits, the smoking rate of workers was low while the alcohol consumption rate was quite high. This study has improved the understanding of the health status of workers in a large oil refinery in Korea, and has shown the impact of lifestyle habits related to the work environment on chronic diseases.

In order to determine the prevalence rate and find out the sexual difference of abnormal electrocardiographic findings manifested by computerized EKG, which is equipped with auto-analyzing function, a total of 2,083 electrocardiograms that were taken from population over 20 years-old from October 1996 to February 1997 were studied according to their age, gender and blood pressure. 1. Using the electrocardiography with auto-analyzing function, 33 kinds of abnormal findings were manifested. The prevalence rate of abnormal findings was 52.8% in male and 43.7% in female. Among them, the most common finding was sinus brady-cardia found in 17.6% of male and 15.4% of female. Left ventricular hypertrophy by voltage criteria, minimal voltage of left ventricular hypertrophy, left axis deviation and atrial fibrillation were more common in male than in female statistically. Both of nospecific T wave and ST segment abnormality were more common in female than in male statistically. 2. Thirty-three kinds of abnormal findings were manifested. They revealed one abnormal finding alone or combined with some other ones making 128 kinds of abnormal finding. The most common abnormal finiding that manifested alone was right axis deviation (100%), then myocardial ischemia (95.7%) the next. The most common abnormal finding that complexed with other abnormal findings were left anterior fascicular block(percentage of single manifestation, 26.2%) and nonspecific T wave abnormality(percentage of single manifestation; 32.9%). Also, combination of sinus bradycardia and minimal voltage of left ventricular hypertrophy, and combination of sinus bradycardia and left ventricular hypertrophy were included in 25th sequences of abnormal findings. 3. The prevalence rate of abnormal electrocardiographic findings were higher in older group, hypertensive group, and the group of higher systolic or diastolic pressure in both sexes. 4. Abnormal findings that commonly manifested with sinus bradycardia were voltage criteria or minimal voltage of left ventricular hypertrophy(38.6%): sinus arrhythmia(10.5%): nonspecific T wave or ST segment abnormality(18.4%) and first degree AV block(7.2%) in descending order. 5. The most common site which manifested myocardial ischemia was posterior and inferior wall with equal percentage of 23.4%. And then anterior wall(19.1%), and antero-lateral wall and septum with equal percentage of 10.6% was noted in descending order.

The purpose of this study is to provide basic data for the children so as to avoid any accidents and to improve their health through a sound and safe living environment with safety education established through more systematic methods. For the study, the methods used include the questionnaires for collecting data which are distributed among 273 children from 3 to 6 years old. They live in three districts of Seoul (Kangnam and Kangbuk), Kyeonggido (Munsan and Ilsan) and Incheon. The children's general characteristics are investigated and the relationship between the accident-proneness prospects and their results are analyzed assuming that children's health is expected to have an effect on their safety. The findings of the study are as follows: 1. The accident-proneness prospect (for the living safety) has significant difference in sleeping habits and physically weak conditions(p<0.05). 2. The accident-proneness prospect (for the traffic safety) has no significant difference in accordance with the children's health condition. 3. Children's reasoning power has no significant difference in accordance with their health condition. 4. Children's movement speed non-significantly differs in accordance with their health condition. 5. Children's movement stability has a significant difference in accordance with their health conditions such as history of mild disease(p<0.05) and physical work capacity(p<0.05). 6. Children's attention power has no significant difference in accordance with their health condition. 7. Children's characteristic activities show a significant difference in accordance with their health history of mild disease(p<0.05). mental health(p<0.05). eating habits(p<0.05) and others (i.e. auditory abnormality and skin desease)(p<0.05). 8. General assessment of the APP test has no significant difference in accordance with their health condition. 9. The health conditions are a significant difference in the history of mild disease in accordance with sex(p<0.05) and whole family members(p<0.001). Also there are shown significant differences. in accordance with sex(p<0.05). in physical work capacity(p<0.05). Eye sight, blood circulation and skin condition show significant differences in accordance with residence(p<0.05) and whole family members(p<0.01). and the condition of eating habits appeared significant in accordance with age(p<0.05). Also, sleeping habits and physically weak conditions shows significant differences in accordance with age(p<0.001) and housing pattern(p<0.01), and others (i.e. auditory abnormality and skin desease) show significant differences in accordance with residence (p<0.001).

Background: Cervical human papillomavirus (HPV) infection among young women (20-25 years of age) is common and normally transient. There are growing concerns that referral to a colposcopy clinic may lead to unnecessary treatment with an increased risk of obstetric complications. Therefore, the purpose of this study was to determine the level of intervention for cervical abnormalities in this age group of the Northern Ireland population. Materials and Methods: A review of all serial new patients under 25 years of age, who were referred to colposcopy clinics in Northern Ireland between January 1, 2009 to June 30, 2009 formed the basis of this study. Results: During the study period, a total of 4,767 women under 25 years of age were screened. Two-hundred-and-thirty-four (4.9%) cases were referred to the colposcopy clinics. The cervical cytology results were: high-grade abnormality in 35%, and low-grade abnormality in 31% of these cases. One-hundred-and-seventy-eight (76%) of the referred women received at least one treatment. One-hundred-and-twenty-one of 234 (51.5%) women underwent an excisional treatment with histology showing the presence of high-grade abnormalities (CIN2-3) in 52%, CIN1 in 28%, and Koilocytosis or normal tissue in 20% of this sub-group of cases. Conclusions: Screening women under the age of 25 years cause unnecessary referral for colposcopy. This may also result in considerable anxiety and psychosexual morbidity. It leads to an over-treatment with a potential of negative impact on the future pregnancy outcomes (including pre-term delivery, low birth weight, and pre-term premature rupture of membranes).

This study was carried out to offer the basic data for more qualitative lives of the middle-aged women through their health maintenance and control. So, the researcher reviewed and analyzed the health problems of the middle-aged women, the differences of main symptoms in each subject, positive ratcs in screening tests, the difference of screening tests with age and the correlation of obesity and blood pressure with screening tests. All subjects were 218 women(40-59years) who had a check-up at a comprehensive health check-up center in K University Hospital in Seoul from July 1, 1998 to August 31. 1998. Questionaires were developed to get subjects, general characteristics. main symptoms, medical examination and diagnosed disease by the researcher referring through the questionaires of comprehensive health check-up center and the medical recorders were used as a tool of study. The researcher analyzed the data with SPSS PC+ ; the distribution of the subjects, general characteristics and main symptoms with percentage : the difference between main symptoms and screening tests with X$^2$-test, ANOVA. The results are as follows. 1) Among the age distribution, most were 40-45 years old and unemployed. 2) The most common complaints were indigestion in digestive system, cough in respiratory system, heart beat in cardiovascular system, general sweat in endocrine system. edema in urinary system, easy bruise in hematologic system, backache in musculoskeletal system, headache in psychoneurologic system, lochia in gynecology, itch in dermatology system, eye ball pain in visual system and tinnitus in auditory system. 3) In main symptoms according to age, the 40-45 age group had a higher rate of complaints in digestive system and gynecology than other age group ; the 46-49 age group in endocrine system. 4) The main symptoms according to diagnosis had no difference statistically. 5) The screening tests which showed high rates of abnormality were mammography(the highest), abdominal ultrasonography, upper gastrointestinal series/gastrofiberscopy, PFT. In all age group the highest rate of abnormality was seen in mammography. 6) In screening tests according to age. the 46-49 age group showed higher positive rates of pap smear, blood sugar test, urine test than any other age group ; the 50-55 age group showerd higher positive rates of obesity, BP, chest X-ray, abdominal ultrasonography, ESR, SGOT, CRP and urine micro. 7) In correlation of obesity with screening test, the obesity group showed higher positive rates of blood pressure, chest X-ray, abdominal ultrasonography, HCT and CRP than the normal weight group. 8) In correlation of blood pressure with screening test, the hypertension group showed higher positive rate of obesity, chest X-ray, abdominal ultrasonography, pap smear and blood sugar than the normal blood pressure group. In conculusion, the middle-aged women have various physical symptoms and affected by age. The obesity and BP have an important effect on the health of the middle aged women. Therefore, this study is considered significant as data for qualitative lives of the middle-aged women playing an important part of family health care by catching of their health problem complaints for prevention of disease and promotion of health.

뇌성마비아의 조기 발견에 관련된 모자인자를 조사하기 위하여 1987년 2월부터 1987년 4월까지 대구 장애자 복지관, 대구대학교 부설재활원, 성바오로 어린이집, 그리고 부산 뇌성마비아복지회에 통원 또는 입원치료를 받고 있는 어린이 110명중 1980년 1월 1일 이후 출생자 74명 전원의 어머니를 대상으로 면담조사 하였다. 아버지의 학력과 이상 발견시기와는 아무런 상관관계가 없었으나 어머니의 학력이 대학졸업이상 일때가 고졸이하에 비해 어린이의 이상을 일찍 발견했고, 또 아버지의 직업이 전문직 또는 관리직일 때가 그 이외의 직업에 비해, 그리고 아버지의 월수입이 610,000원이상 일때가 600,000원 이하보다 더 일찍 발견하는 경향이었다. 첫째아이가 둘째아이 보다 그리고 부모의 나이가 34세 이하인 경우가 35세 이상인 경우에 비해 좀더 일찍 이상을 발견하는 경향을 보였다. 남아에서 여아에 비해 더 일찍 이상이 발견되었고 육아상담을 정기적으로 받은 어린이에서 정기적으로 받지 않은 어린이보다 더 일찍 이상이 발견되었는데 5% 유의수준에는 약간 못미쳤다. 연구대상아를 임신했을 때 산전관리를 7회이상 받았던 경우가 6회이하 받았던 경우에 비해 통계적으로 유의하게 일찍 어린이의 이상이 발견되었다. 처음으로 이상을 발견한 사람은 부모가 85.1%, 육아 상담을 정기적으로 받은 여부와는 관계없이 의사가 발견한 것은 2.7%였고 부모가 어린이의 이상을 발견하고 의사의 진단을 받았을때 36.5%에서 뇌성마비 진단을 받았고 나머지는관찰, 정상등으로 진단이 확실하지 않았다. 부모가 어린이의 이상을 발견하고 $2{\sim}3$개월 뒤에 의사의 진단을 받았고 진단후 전문적 치료를 시작할 때까지 방치했거나 물리치료, 한약, 침술 등을 받았다. 뇌성마비아의 조기 발견을 위해 의학교육과 임상수련과정에서 어린이의 발달을 평가하는 방법의 교육과 수련이 강화되어야 할 것이며 진단을 위한 전문인력의 양성이 필요한 것으로 생각된다. 또 부모들의 뇌성마비를 비롯한 각종 장애의 진단과 치료에 대한 인식을 높이기 위한 계몽교육이 필요하다.

Abnormality in the central noradrenergic system may be related to the seizure prone state in the genetically epilepsy prone rats (GEPR). The present work deals with the characterization of the deficit in noradrenergic system if susceptitibility and intensity of seizure are dependent on central noradrenregic activities by comparing the activities of dopamine $\beta$-hydroxylase (DBH) which hydroxylates dopamine into noradrenaline. DBH activities were measured in 5 areas of brain of normal rats, native GEPR and severe GEPR. The results suggest that lower DBH activities in the midbrain of GEPRs may positively be coupled to the susceptibility to seizure, whereas the same characteristics of the native or severe GEPR are not neccessarily in parallel with the intensity of seizure.

I have processed all the data by using SPSS PC+. And my research process was investigated for 34 students on the Forward Bending Test, Foot Printer Test, Feedoscope Test, X-ray Test and so on. The object of this thesis is to study the correlation between spine deformity and foot abnormality in a theoretical and empirical method. The main results of this study were as follows: 1. There was statistical significance on the correlation between foot length and spine length. 2. Spinal curve is the smallest on the pes plannus group and the biggest on the pes cavus group without statistical significance. 3. Left lumbar curve is the smallest, and right thoracic spine curve is the biggest on the left foot pattern group with statistical significance. 4. On the foot weight bearing groups, there was statistical significance both of between left and right foot groups. 5. There was no statistical significance on the t-test analysis between left and right foot area according to spinal curve typology. But there was tendency that thoracic spine curve is bigger in the same side of the foot area and lumbar spine curve is bigger in the opposite side of foot area.
