This study was evaluated about the seasonal variations of ecosystem in Nammae Reservoir based on the interrelation of physco-chemical characteristics, nutrients, chlorophyll a, b, c and standing crops of phytoplanktons. The amounts of chlorochlorophyll a, b, c were respectively maximum (295 mg/l, 9.5mg/l and 48mg/1) at station 1 in June and the standing crop of phytoplanktons was the highest (1.7×10^5 cells/l) at stations 3 in July. The range of temperature was 7~37.4℃. The maximum of pH was 9.9~10.1 at all stations in August, the minimum was 7 in September. SS was maximum (308 mg/l) at station 1 in June, while it was minimum(4mg/1) at the same station in November. The maximal COD and DOC were 33 mg/l and 16 mg/l respectively at station 1 in June. As for phytoplanktons, Microcystis aeruginosa, blue-green alga in July~August, Scenedesmus acutus, green alga in March~May and November~January and Cyclotella orientalis, Diatoms in October were dominant species. The amounts of P and Si were generally high in summer, they were low in autumn and winter. Nammae Reservoir assessed by trophic state index was eutrophicated and overtrophicated. These results indicated that Nammae Reservoir was faced with heavy water pollution. As preceding management for the basin of the Reservoir, it will have to be continually studied for an ecosystem reservation.

Twenty-three patients with pleural effusion of unknown etiology were selected because by means of radiological and cytologic examination, smear of the sputum and pleural fluids for tubercle bacilli and eggs of the lung fluke had failed to provide a diagnosis, from September, 1974 to October, 1975 at the Department of internal Medicine, National Medical Center in Korea. Needle biopsy of the pleura using Vim-Silverman needle, culture of the sputum and pleural fluids for tubercle bacilli, red blood cell, lymphocyte, monocyte and mesothelial cell counts in the pleural fluids, and measurement of the pleural fluid glucose and pH levels were done to provide definite or suspected diagnosis. The results were as follows: 1) neeedle biopsies were done on 23 patients and 11 of these showed tuberculous findings, 2 of these showed lymphoma and the remaining 10 showed nonspecific chronic inflammation (43.5%). In one patient of the nonspecific group, an open pleural biopsy which showed paragonimiasis. 2) culture of the pleural fluid was positive for tubercle bacilli in only 2 of the tuberculous group and 1 of the nonspecific group. 3) Used in conjunction with pleural fluid red blood cell, lymphocyte, monocyte, rresothelial cell counts and glucose, pH levels, most provable tuberculous etiology could be established in 6 of 8 nonspecific group, and remaining 2 were as idiopathic pleural effusion. There was no significant statistical difference in the laboratory
