Fatty liver is caused by derangement of fat metabolism and can be reversed by removal of contributing factors. The contributing factors of fatty liver is known to be overweight, chronic alcoholism, diabetes mellitus, malnutrition, and drug abuse such as tetracycline. This study was carried out on 1335 persons who visited 'Soon Chun Hyang Human Dock Center' from March to June 1990. In analysis of the data, prevalence of fatty liver diagnosed by ultrasonogram by age and sex, laboratory finding between fatty liver group and normal group, and odds ratio of known contributing factors, were compared. The results obtained are as following ; 1) The prevalence rate of fatty liver diagnosed by ultrasonogram is 29.6% in male and 11.5% in female. 2) Age groups with high prevalences are $40{\sim}50's$ in male (32.0%) and 50's in female (24.5%). 3) The fatty liver shows significant association with style (p<0.05), whereas not with hepatitis B-virus surface antigen (p>0.05). 4) All laboratory values except alkaline phosphatase and bilirubin are elevated significantly in accordance with the degree of fatty liver (p<0.01). 5) Fatty liver diagnosed by ultrasonogram showed so strong associations with body index, triglycerides and gamma-glutamyl transferase for males, and body index and fasting blood sugar for females that these factors may be used as supplementary data in establishing diagnosis of fatty liver. 6) Odds ratio of contributing factors are as follows ; If the odds ratio of below 29 year of age is 1.0 then that of $30{\sim}39$ is 1.74 (p=0.33), $40{\sim}49$ is 2.47 (p=0.10), $50{\sim}59$ is 2.86 (p=0.0570), over 60 is 1.81 (p=0.34). If the odds ratio of female is 1.0 then that of male is 5.67 (p<0.01). If the odds ratio of body index below zero is 1.0 then that of $0{\sim}9$ is 5.08 (p<0.01), $10{\sim}19$ is 12.37 (p<0.01), $20{\sim}29$ is 29.19 (p<0.01), 30 above is 154.02 (p<0.01). If the odds ratio of below 99 mg/dl FBS is 1.0 then that of $100{\sim}120$ is 106 (p=0.76), over 120 is 1.91 (p=0.02). If the odds ratio of below $29{\mu}/1{\gamma}-GT$ is 1.0 then that of $30{\sim}s59$ is 2.11 (p<0.01), $60{\sim}90$ is 1.87 (p<0.05), 90 above is 1.69 (p=0.15). If the odds ratio of below 149 mg/dl TG is 1.0 then $150{\sim}199$ is 1.49 (p=0.05), $200{\sim}250$ is 1.09 (P=0.77), 250 above is 2.53 (p<0.01). In summary, early diagnosis of fatty liver could be made by ultrasonogram supplemented with body index and nm triglyceride. The fatty liver could be preventive by avoiding contributing factors such as obesity, alcohol intake, high blood sugar appropriately.

안재억,김귀숙 대한의료정보학회 2004 Healthcare Informatics Research Vol.10 No.1

This study was conducted to collect data on the educational needs for hospital administrations and related departments to redesign the existing hospital information management and administration programs for Bachelor and Master degree students of medical informatics in one university. We surveyed the web sites and admission brochures of all the educational facilities of hospital administration related workers in Korea. We also surveyed hospital workers in hospital administration departments at three university affiliated hospitals using a questionnaire developed by the author. The survey results showed that most hospital employees indicated a need to take very fundamental classes in their fields. In order to satisfy the needs of the students up to date, the department of medicine in one university developed a new medical informatics course specially designed for Bachelor and Master degree students in hospital administration. In addition, the Graduate School of Industrial Information Engineering of one university decided to offer basic as well as a specialized training courses for the graduate students who are hospital administrators.

안재억,김남수,이병국,박정선,김양호 한국산업안전보건공단 산업안전보건연구원 2019 Safety and health at work Vol.10 No.4

Objectives: We evaluated the physical and mental health problems of waged workers in Korea who had different classes of occupation. Methods: We used data from the Korean National Health and Nutrition Examination Survey (2007e2017) to examine 22,788 workers who were waged employees and categorized these workers into 5 occupational classes. Results: “Unskilled manual workers” were more likely to be older, less educated, have lower monthly income, and work fewer hours per week. Among men and relative to “managers and professionals” (reference group), “skilled manual workers” were more likely to have physician-diagnosed osteoarthritis, “clerks” were less likely to report suicidal ideation, and “unskilled manual workers” were more likely to report suicidal ideation. Among women and relative to “managers and professionals” (reference group), “service and sales workers” and “unskilled manual workers” were more likely to report physiciandiagnosed osteoarthritis, depressive feelings, and suicidal ideation. However, hypertension, hyperlipidemia, diabetes, and cardiovascular diseases did not differ among the occupational classes for men and women. Conclusion: We identified differences between men and women and among those in different occupational classes regarding employment status, physical health, and mental health. “Unskilled manual workers” of both genders were more likely to be older, less educated, have less monthly income, work fewer hours per week, and have suicidal ideation. Female “service and sales workers” were more likely to have osteoarthritis, depressive feelings, and suicidal ideation.

Using the infrared interactance(NIR method), the percentage body fat in 1,401 Korean children, aged 6-18years, was evaluated for normal and standard values. Correlation of percentage of body fat with age, weight, height, overweight(%), Kaup index and Rohrer index was also analyzed. The following results were obtained ; 1) In all the subject, weight and height showed standard growth(50-90 percentile) compared to growth data of korean children. 2) The percentage of body fat was decreased with increasing age and was measured higher in female than male. 3) The percentage of body fat was decreased with increasing height in both sex. 4) The percentage of body fat correlated negatively with age, heght, weight in both sex. In boys, the Rohrer index appeared to have a significant positive correlation with the percentage of body fat. (r=0.52454) In girls, the overweight(%) appeared to have a significant positive correlation with percentage of body fat. (r=0.56994) The Kaup index had no correlation with the percentage of body fat. This NIR method is safe, non-invasive, rapid, easy to use, and may be useful predict percentage of body fat, especially in the mass screening.

신생아에서 자세 및 경사도에 따른 경피적 산소와 이산화탄소의 분압 및 경피적 산소 포화도의 변화에 대한 연구

To determine the optimal positino for the newborn, tcp02, tcpc02 and Sp02 were monitored, in 21 healthy term infants, in 21 healthy preterm infants and in those infants with respiratory disease using the Radiometer(Cophenhagen) TCM2 TC oxygen monitor, ECM 20 TC carbon dixide monitor and PULSOX-7(Minolta) oxygen saturation monitor in both supine and prone position. Also, monitored with tilting in each position. When the healthy preterm infants were prone, tcP02 rose by a mean of 5.8mmHg(p=0.0185), an increase of 8.7%, and Sp02 was not significantly increased by a mean of 0.6%(p=0.1859). In those infants with respiratory disease, tcP02 was not significantly increased by a means of 6.9mm/Hg(p=0.1014), and Sa02 was not significantly changed. There was no change of tcPC02 in all infants. This improved oxygenation in the prone position appears to be the result of enhanced ventilation/perfusion ratios. Tilting the body in a 20head-down, or 20 head-down partially produce significant change in tcP02, or Sp02 in the newborns. These findings may have important implications in the management of preterm infants requiring neonatal intensive care and the infants with respiratry disease.

안재억(Jae-Ouk Ahn) 한국의학교육학회 2005 Korean journal of medical education Vol.17 No.2

Purpose: To establish a medical informatics curriculum for premedical students. Methods: The author conducted a questionnaire survey on 202 second year premedical students from two medical schools, one in Seoul and one in Asan. The chi-square test was used to do a statistical analysis comparison of the results from these two school groups. In addition, the reliability test was used for the questionnaire s reliability. Results: The results of the survey show that computer skills in second year premedical students differ by gender. The results also indicate that differences exist between the two schools, as the curriculums of the freshman year differ between the schools. Moreover, it is observed that more than 60 percent of the subjects have difficulties dealing with complicated problems such as fixing or replacing hardware. Conclusion: The survey was conducted to assess the level of computer skills in premedical students at two medical schools. Through careful analysis of this survey, we were able to define the necessary level of computer skills required in premedical students in the Medical Informatics curriculum.

Self-rated Subjective Health Status Is Strongly Associated with Sociodemographic Factors, Lifestyle, Nutrient Intakes, and Biochemical Indices, but Not Smoking Status: KNHANES 2007- 2012

박선민,안재억,이병국 대한의학회 2015 Journal of Korean medical science Vol.30 No.9

Despite advertised health warnings regarding the deadly hazards of smoking, many people have not heeded recommendations to quit smoking. We examined factors that affect selfrated subjective health status (SRH) scores among lifestyle, nutrient intake and biochemical parameters, and the association of SRH scores and smoking status in a large Korean adult population. Adjusted odd ratios for SRH were calculated for smoking status, selected biochemical data, and food and nutrient intake obtained using the 24-hr recall method after covariate adjustment in the 2007-2012 Korean National Health and Nutrition Examination Survey (27,534 men and women aged ≥ 20 yr). Age, sex, income, education, drinking, exercise and stress levels were associated with SRH scores, regardless of smoking status (P < 0.001). Interestingly, people in any smoking status groups considered the well-known indicators for metabolic diseases (HDL cholesterol, glucose, aspartate aminotransferase, and alanine aminotransferase in the circulation), and the intake of fiber, total vitamins A, and vitamin C as indicators of SRH. Especially in current smokers, higher intake of nutritious food groups such as grains (OR = 1.227), vegetables (OR = 1.944), and milk (OR = 2.26) significantly increased the adjusted odds ratio of SRH. However, smoking status was not associated with SRH scores. In conclusion, SRH is affected by the indices related to health but not smoking status in Korean adults. The development of a new indicator of the direct adverse effects of smoking at regular health check-ups might be required to modulate the SRH in smokers and a nutritional education should not include the possible attenuation of adverse effects of smoking by good nutrition.
