Broncholithiasis has been recognized in medicall literature for centuries. Because of the relative infrequency, broncholithiasis has often been neglecteed in the differential deagnosis of bronchial obstruction. In this case, we could remove the broncholith obstructing the right middle lobar bronchus with the fiberoptic bronchoscope in a 37-year old man without any complications and the complete resolution of the pneumonia was followed.

To evaluate the relationship between coronary artery disease(CAD) and the various levels of lipid and lipoproteins, we performed coronary angiography to the patient, who were suspected coronary artery disease from January 1988 to August 1989. And compared it with normal control group. The number of control group were 41(21 men, 20 women), and the patient group were 52(42 men, 10 women). The age was not differ between two groups. The results were as follows; 1. In CAD group, the plasma concentration of total lipid, triglyceride, total cholesterol, phosphlipid, and TC/HDL ratio were significantly higher than in control group. But, though, the concentration of HDL was lower in CAD group, had no significant difference between two groups. 2. The severity of CAD were well correlated with total lipid, cholesterol, LDL, trigylceride, phospholipid, TC/HDL, LDL/HDL levels. HDL level didnt's show significant correlation with the degree of CAD. We concluded that total lipid, cholesterol, trigylceride TC/LDL ratio were valuable markers of CAD in Korean, but futhur studies of lipoproteiins and other risk factors in the large population will be recommended.

In this paper, applications of adaptive fuzzy controller to position control of flexible beam are considered. When a flexible beam is rotated by a motor through the fixed end, transverse vibration may occur. The architecture and learning underlying adaptive networks based fuzzy inference system (ANFIS) is presented, which is a fuzzy inference system implemented in the framework of adaptive networks. By using a hybrid learning procedure, the proposed ANFIS can construct an input-output mapping based on both human knowledge and stipulated input-output data pairs. Therefor, a dynamic model for a flexible beam is derived, and then a comparative analysis was made with before learning and after learning adaptive fuzzy controller through an simulation. The results are presented to illustrate the advantages and improved performance of the proposed position control cver the after learning adaptive fuzzy controller.

N/A We studied 12 cases of gastric anisakiasis who contacted the Dept. of Internal Medicine of St. Mary's Hospital and Sun Rin Hospital, Pohang, from March 1986 to Feb. 1989 and were confirmed by gastrofiberscopic findings and removal of larva of Anisakis. Our analysis gave the following results: 1) Of 12 cases, the sex ratio was 1 to 1,4 (male to female) and the 40s age group was most common, followed by the 30s, the 20s and 60s, in order of frequency. 2) In terms of seasonal incidence, May to July showed 6 cases (50%). Among causative fish, Astroconcer myriaster caused 6 cases (50%) and showed highest freguency. 3) The most common symptoms when the patients contacted the hospital were epigastric pain in 9 cases (75%) followed by nausea, epigastric fullness, and vomiting in order of frequency. 4) The onset of symptoms in 8 cases (66.7%) was within 6 hours since ingestion of those fish. 5) Six cases (50%) underwent gastrofiberscopic exam within 24 hours of onset of symptoms. 6) The most commonly involved site of the stomach was the anterior wall of the mid body (4 cases). The gastrofiberscopic findings were, in frequency of incidence, normal mucosa with larva (5 cases), erosion, hyperemia, mucosal thickening, petechia and ulceration. 7) We performed a biopsy in 4 among 12 cases, and the microscopic findings of the gastric mucosa were congestion and edema, broadening of the foveolar ridge and inflammatory cell infiltration, especially eosinophils and lymphocytes. The antral mucosa revealed findings of chronic superficial gastritis and small fragmental necrotic debris was seen along the surface of the mucosa. Early gastroscopic examination may be very useful in the diagnosis and treatment of anisakiasis if anisakiasis is clinically suspected, In addition, the general public should be enlightened that ocean fish are not necessarily safe when they are eaten a raw and a more detailed epidemiologic study should be conducted for anisakiasis.
