The importance of human factors has been emphasized for pilots because most of aviation accidents have been caused by the human factors of pilots. Human factors issues such as fatigue affecting flight safety are needed to be educated to student pilots who have less experience in flight training. In order to prevent aviation accidents caused by human factors, the management of stress, fatigue, and obsessive-compulsive disorder which increase psychological harmful factors of student pilots, is essential for aviation safety. The management of fatigue is required as a part of safety management system following the guidance of leading aviation authorities. The purpose of this article was to investigate the factors of fatigue at each stage by classifying it into before, during, and after flight training to manage the fatigue of students pilots. Then, the factors of relatively high fatigue were analyzed by using the AHP process to provide factors related fatigue affecting pilot training.

Behcets syndrome is an uncommon entity of unknown etiology characterized by ulcerations of the buccal and genital mucosa, skin lesions, and ocular inflammation. It has been reported to be associated with pathological involvement of every organ system of the body, including the colon (though this is unusual). A fatal outcome due to involvement of gastrointestinal tract has been described by Saugmann Jensen (1944). We have recently seen a 34-year-old man who had had colitis in Behcets syndrome. He had had relapsing genital ulcers, fever, abdominal pain and diarrhea. Gradually diarrhea worsened, there was general deterioration, abdominal pain, weight loss and fever. Colortqfiberscopic finding revealed a large ulcer on the cecum which was suggested as chronic inflammatory ulceration associated with diffuse vasculitis. The patient was treated with the combined antibiotics with corticosteroid but there was no observable response. Right hemicolectomy with ileal resection was performed with transient improvement but the second surgery of enterocutaneous fistula had done a month later. However, he died in cachexia on 45th hospital day.

저자들은 전흉통 및 심계항진을 주소로 내원한 60세 여자 환자에서 관동맥 조영술을 실시하여 좌측 관동맥 전하방 분지(Left Anterior Descending Artery)의 중간부위에서 심근수축기 약 90%의 협착을 보이는 "Milking Effect"를 동반하는 심근교락(Myocardial Bridging) 1예를 경험 하였기에 문헌고찰과 함께 보고하는 바이다. Myocardial bridging is a condition that with abnormal intramyocardial course of coronary artery, the artery can constrict during the systole and may result in myocardial ischemia and symptoms. The incidence of intramyocardial segment of the coronary artery is found in approximately 20% of autopsied hearts and the angiographic evidence is seen in 0.5% of patients undergoing coronary angiography for chest pain. The origin of this arterial anomaly is probably congenital in light of the intramural location of coronary artery during embryonal life. This 60-year-old female patient was admitted to the hospital because of anterior chest pain and palpitation for 2 months. Abnormal electrocardiographic findings (S-T wave depression, inversion of T wave and tachycardia) were shown only when symptoms occured. The coronary angiography showed characteristic systolic constriction of a segment of the left anterior descending artery and constriction disappears during diastole. Here we report one case of myocardial bridging with milking effect in 60-year-old female patient with the review of literatures.

당뇨병 환자에서의 골변화를 보기위해 1989년 2월부터 1990년 9월까지 본 병원 내과에 입원했던 150명을 대상으로 microdensitometry에 의한 각지표와 그 지표를 점수로 환산한 점수합을 이용하여 다음과 같은 결과를 얻었다. 1) 150명의 환자중 110명의 인슐린 비의존성 당뇨환자에서는 50명(46%)에서는 정상이었고 31명(28%)은 초기, 17명(15%)에서는 Ⅰ도, 8명(7%)에서는 Ⅱ도, 4명(4%)에서는 Ⅲ도의 골소실을 보였고 40명의 대조군에서는 32명(80%)에서 정상이었고 8명(20%)에서 초기 소견을 보였다. 2) 골감소가 없는 당뇨병환자와 골감소가 있는 당뇨병환자에서 혈청 칼슘, 인, 알카리성 인산분해효소, 부갑상선 호르몬의 의미있는 차이는 없었다. 3) 골감소가 초래된 당뇨병환자에서 골감소가 초래되지 않은 환자사이의 당뇨병 이환기간, 공복 혈당 및 HvAlc이의 의미있는 차이는 없었다. Utilizing the microdensitometer, we observed the incidence of osteopenia in patients with 110 non-insulin dependent diabetes mellitus(NIDDM) and 40 control group. Also to assess the relationship between the osteopenia in NIDDM and calcium metabolism, we measured the serum calcium, phosphate, alkaline phosphatase activity and PTH. The results were summarized as follows; 1) The number of initial stage in diabetic patients was 31. There were 17 in degree Ⅰ, 8 in degree Ⅱ, 4 in degree Ⅲ. The number of initial stage in control group was 8. 2) The change of calcium metabolism indices such as serum calcium, phosphate, alkaline phophatase activity and PTH was not observed. 3) As to the clinical characteristics of osteopenic diabetic patients, we found no difference in the duration of diabetes, fasting blood sugar, and HbAlc between osteopenic and nonosteopenic group.

복강내 악성질환에 있어서의 복수 Carcinoembryonic Antigen 측정의 진단적 의의

박창영,이만호,김광조,이상종,전승준,유영석 대한소화기학회 1991 대한소화기학회지 Vol.23 No.1

Ascites may be caused by various benign and malignant diseases but it is sometimes difficult to determine whether the ascites is caused by benign or malinant diseases. Various diagnostic methods such as ascitic level and ascites/serum ratio of protein and LDH, cytology and peritonioscopy have been used in differentiating between benign and malignant ascites. Carcinoembryonic antigen (CEA) level in pleural effusion is known to be useful bo make the diagnosis of malignant disease in thoracic cavity. Lowenstein et al. (1978) reported that CEA level in ascites was many-fold higher than in serum in patients with malignant disease and ascites. In order to determine whether ascites CEA is of help to make diagnosis of malignant diseases in abdominal cavity, both ascites CEA and serum CEA were measured and analyzed in 49 patients with ascites who were admitted to this hospital from June 1988 to December 1990. The results are as follows: 1) The mean value of CEA level in ascites and serum in benign ascites group was 1.47 ng/㎖, 2. 40 ng/㎖, respectively. The upper limit of ascites and serum CEA in benign ascites group was 3. 37 ng/㎖, 5.56 ng/㎖, respectively. 2) The CEA level of malignant ascites group was significantly higher than that of the benign ascites group in ascites (p$lt;0.05) and in serum (p$lt;0.05). 3) Ascites CEA level was higher than 3.37 ng/㎖ in 10 of 25 patients with malignant ascites (40%), and 1 of 24 patients with benign ascites. (4%) In 4 patients, ascites CEA level was higher than 100 ng/㎖, all of them have malignant diseases in abdominal cavity. 4) Serum CEA level was higher than 5.56 ㎎/㎖ in 10 of 25 patients with malignant ascites (40%), and 3 of 24 patients with benign ascites (12%). In 4 patients, serum CEA level was higher than 100 ng/㎖, all of them have malignant diseases in abdominal cavity. 5) The specificity of ascites CEA for malignant disease in abdominal cavity was 96.0% positive predictability 91.0%, sensitivity 40.0%, and negative predictability 60.0%. 6) The specificity of serum CEA for malignant disease in abdominal cavity was 88.0%, positive predictability 77%, sensitivity 40.0% and negative predictability 58.0% 7) The cases of which ascites CEA level was greater than 3.37 ng/㎖ was divided into hepatoma group (27%) and nonhepatoma group (73.0%), each mean value was 18.45 ng/㎖, and 33. 57 ng/㎖, respectively. In summary, the measurement of ascites CEA level is useful in differentiating the existence of malignant diseases in abdominal cavity.

Lymphangiomas are benign congenital malformations of the lymphatic system usually affecting the neck and axilla. Involvement of the visceral organs is less common. Splenic involvement is quite rare and only a few cases have been reported in this country. We experienced recently two cases of splenic lymphangiomatosis who underwent successful surgical resection. Case I: A 31-year-old woman presented with right upper quadrant abdominal dull pain of three years duration, Physical examination disclosed mild tenderness without palpated mass in the right upper quadrant. Laboratory examinations including routine CBC and blood chemistry were all within normal limits. Both sonography and abdominal CT were interpretated as cholesterol polyp of the gall bladder and splenic tumors such as hemangioma or lymphoma. Both splenectomy and cholecystectomy were performed. The histologic findings were lymphangiomatosis of the spleen and adenomatous polyps of the gall bladder. Case II: A 66-year-old woman was admitted to this hospital because of intermittent aching pain in the right upper quadrant over several years period. Physical examination revealed mild tenderness without any palated organs or mass in the right upper quadrant. Laboratory examination included routine CBC and blood chemistry was within normal limits except a slighty increased SGOT and SGPT and marked elevated ESR. Sonography suggested an adrenal or pancreatic tumor, but abdominal CT suspected a splenic tumor. An angiogram including the abdominal aorta, splenic and renal artery suggested a splenic benign tumor. The histologic diagnosis was lymphangliomatosis of the spleen. The histologic finding of the hepatic biopsy elicited chronic hepatitis.
