This study has been conducted in the field, not in the library, as to why scuba divers don't activate precautionary decompression stop system by observation under the water and conducting interviews. With the materials acquired through the interviews, I tried to analyse the reasons along with a group of experts. As a conclusion, I introduced the three criteria for the theme. The first is the environmental factors: the undercurrent, the lack of descending lines, and the attacks of jelly fish. For these, they need to install the decompression stage, use the diving sausage, and wear suits and hoods appropriate for the surrounding conditions so that no problems arise even when the precautionary decompression stop system malfunctions. The second is the psychological factors: the anxiety arising from the excessive use of depressed air, the problems with colleagues, the anxiety arising from the dim sights and the noise out of boats' engines, and the insensitivity out of mannerism as a long-experienced expert of scuba diving. It is analysed that these problems can be largely solved out by the exercise of how to control the air, the recognition of how important buddy divings are, the practice of calmness under precarious environments and the skills of checking gear and gauge, and, most importantly, being alert through the education about the accident cases to recognize how important the device is. The third is the institutional factors: the lax training disciplines caused by the well-intention of guides and instructors trying to help their club members, the lack of proper educational standards, and the lack of proper screening process to single out the instructors with the low level of skills. Throughout these efforts, it is expected that the trust between club members and instructors will be restored, the instructors will try harder, the education centering on the problem-solving will set in place, the feed-back system to reeducate the instructors will be offered, throughout which the overall quality of diving will improve.

N/A Background : It is well known that non-alcoholic fatty liver disease is associated with metabolic syndrome such as obesity, type II diabetes mellitus, dyslipidemia. Non-alcoholic fatty liver disease is frequently found in non-obese adults, but the meaning of it is unknown. So we studied the association of non-alcoholic fatty liver disease in non-obese adults and metabolic abnormalities. Methods : We examined 779 Korean adults above 30 years old (274 men, 505 women) participating in medical check-up in Health Promotion Center. Hepatitis B and C serologies were negative, and average weekly alcohol intake was .2 drinks. A standard interview, physical examination and biochemical study was conducted. An experienced operator carried out ultrasound liver studies. Results : 370 subjects had non-alcoholic fatty liver disease (47.3%). The frequency in men was higher than that in women (57.3 vs 42.2%, p<0.05). The frequency in non-obese (BMI<25 kg/m2, n=431) group was lower than that in obese (BMI.25 kg/m2, n=348) group (65.5 vs 32.3%, p<0.05). Compared with obese group, waist circumference, waist hip ratio, body fat, impaired fasting serum glucose, total cholesterol, HDL-cholesterol, total cholesterol to HDL-cholesterol ratio, fasting insulin, proinsulin, HOMA-IR and HOMA-beta were significantly different in non-obese, non-alcoholic fatty liver group. After multiple regression analysis, waist circumference was associated with non-alcoholic fatty liver disease in non-obese individuals. Odd ratios of insulin resistance in non-obese, non-alcoholic fatty liver group were 5.8 (CI: 3.1.10.9). Conclusion : The frequency of non-alcoholic fatty liver disease was very high in non-obese adults and well associated with central obesity and insulin resistance.(Korean J Med 63:488-495, 2002) Key Words : Non - alcoholic fatty liver disease, Body mass index, Metabolic syndrome, Central obesity

As the computerization of hospitals becomes more advanced, security issues regarding data generated from various medical devices within hospitals are gradually increasing. For example, because hospital data contains a variety of personal information, attempts to attack it have been continuously made. In order to safely protect data from external attacks, each hospital has formed an internal team to continuously monitor whether the computer network is safely protected. However, there are limits to how humans can monitor attacks that occur on networks within hospitals in real time. Recently, artificial intelligence models have shown excellent performance in detecting outliers. In this paper, an experiment was conducted to verify how well an artificial intelligence model classifies normal and abnormal data in network traffic data generated from medical devices. There are several models used for outlier detection, but among them, Random Forest and Tabnet were used. Tabnet is a deep learning algorithm related to receive and classify structured data. Two algorithms were trained using open traffic network data, and the classification accuracy of the model was measured using test data. As a result, the random forest algorithm showed a classification accuracy of 93%, and Tapnet showed a classification accuracy of 99%. Therefore, it is expected that most outliers that may occur in a hospital network can be detected using an excellent algorithm such as Tabnet.

목적: 본 연구는 한국인 성인에서 인슐린저항성에 따른 대사증후군과 그 구성요소들의 유병률을 분석하기 위하여 수행하였다. 대상 및 방법: 한국건강관리협회에서 건강검진을 받은 30세 이상 성인 남녀 1,091명을 무작위로 추출하여 혈당, 혈청 인슐린, 총콜레스테롤, HDL-콜레스테롤, 중성지방, 체질량지수, 허리둘레, 혈압, 경동맥 내막중막두께 및 복부초음파를 시행하였고, 대상군을 인슐린저항성 정도에 따라 인슐린감수성군, 중간군, 인슐린저항성군으로 삼등분하여 그들의 임상 및 검사결과에 따라 대사증후군의 발병률을 분석하였다. 결과: 인슐린감수성군과 비교할 때, 인슐린저항성군에서 대사증후군의 상대위험도는 84.1배 증가하였고, 당뇨병 및 내당능장애는 10.2배, 고혈압은 1.8배, 이상지혈증은 2.8배, 고콜레스테롤혈증은 2.5배, 지방간은 3배 증가하였고, 전신성비만보다 복부비만이 인슐린저항성에 더 기여하는 것으로 나타났다. 결론: 본 연구는 단면적으로 수행되었으나, 인슐린저항성이 대사증후군의 중요한 위험인자이고, 심장혈관질 환을 비롯한 성인병의 예측인자로써 큰 의미가 있음을 시사한다. 따라서 성인병의 예방을 위해서 앞으로는 건강검진에 인슐린저항성을 평가하는 항목을 도입할 것을 권장한다. Background: This study was initiated to evaluate the prevalence of metabolic syndrome and its components as risk factors for cardiovascular disease according to insulin resistance in the Korean adult population. Methods: This study was conducted as a branch of the Korean Metabolic Syndrome (KMS) Study: 1,091 individuals aged 30 79 years participating in medical check-up in Korea Association of Health (KAH) were included in this study. We checked fasting blood sugar, fasting insulin, proinsulin, lipid profiles (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol), body mass index, waist circumference, blood pressure, carotid intima-media thickness (IMT) and abdominal ultrasonography. We divided all of the examinees into three groups (insulin sensitive, intermediate, resistant tertiles) according to their degree of insulin resistance and correlated this with the prevalence of metabolic syndrome. Results: The relative risk of metabolic syndrome was 84.1-fold higher in the insulin resistant tertile group compared to the insulin sensitive tertile group. Diabetes mellitus or impaired fasting glucose (IFG) was 10.2-fold; hypertension, 1.8-fold; dyslipidemia, 2.8-fold; hypercholesterolemia, 2.5-fold; fatty liver, 3.0-fold. Abdominal obesity rather than general obesity was more contributory to insulin resistance. Conclusion: Although this is a cross-sectional study, we can show that insulin resistance is one of the most-striking risk factors in metabolic syndrome and can be used as a predictor of cardiovascular diseases. Furthermore, we should monitor the healthy insulin-resistant population to prevent ongoing cardiovascular diseases. More prolonged data should be gained to refine the correlations of insulin resistance to metabolic syndrome.(Korean J Med 63:54-60, 2002)

Acute hepatitis associated with Q fever is rare. Clinician awareness is key for early diagnosis. It can be treated well with macrolides, and symptoms and antibody titers decrease in weeks or months according to the treatment regimen. Successful therapy is accompanied by reduced erythrocyte sedimentation rate, correction of anemia, and resolution of hyperglobulinemia. The risk of chronic Q fever is high if symptoms and antibody titers persist during long-time follow-up testing. Here we report a case of a 54-year-old male with acute Q fever and hepatitis. He complained of fever and headaches and presented with elevated ALT levels around 400 IU/L at admission. Liver biopsy revealed compact fibrin-ring granulomas. He recovered from the acute hepatitis after one week of ciprofloxacin therapy. However, although the patient remained asymptomatic 8 months after completing treatment, his phase 1 and 2 antibody titers remained high. We are unable to determine the disease stage; that is, whether the acute stage was completely resolved due to high titer of antibody.
