Hypophosphatemia is a relatively common findings in hospitalized patients, especially severe hypophos- phatemia has been associated with significant morbidity. We reviewed severe hypophosphatemic patients who admitted in National Medical Center between January, 1989 and December, 1989. The following results were obtained. 1) The incidence of hypophosphatemia was 9.6%(364 of 2762) and 44 patients (3.3%) showed severe hypo-phosphatemia. 2) Contributing causes were intravenous glucose administration, antacids treatment, diarrhea and fasting in order of frequency. 3) Other electrolytes abnormalities were hypocal- cemia (54.5%), hypomagnesemia (57.2%), hyponatremia (31.8%) and hypokalemia (27.3 %). 4) Fifteen patients (34.1%) with severe hypophos-phatemia showed abnormal renal function. 5) The odds ratio for developing the severe hypophos- phatemia was 43.1 (95% confidence interval 2.9 to 623.6) in patients with diabetic ketoacidosis, 30.1 (10.8 to 83.8) in septic patients, 9.9 (1.2 to 82.6) in alcoholics, and 9.2 (l. 1 to 75.7 ) in malnourished patients. 6) Overall mortality of patients with severe hypo-phosphatemia was 27.3% (12 of 44). From the above results, we conclude that severe hypophosphatemia is a relatively common finding in hospitalized patients, especially in those with certain medieal conditions (diabetic ketoacidosis, septicema, aicoholics & malutrition). It is associated with significant excess morbidity.
Hot carrier 현상에 의한 CMOS 차동 증폭기의 성능 저하

The performance degradation of CMOS differential amplifiers due to hot carrier effect has been measured and analyzed. Two-state CMOS amplifiers whose input transistors are PMOSFETs were designed and fabriacted using the ISRC CMOS 1.5.mu.m process. It was observed after the amplifier was hot-carrier stressed that the small-signal voltage gain and the input offset voltage increased and the phase margin decreased. The performance variation results from the increase of the transconductances and gate capacitances of the PMOSFETs used as input transistors in the differential input stage and the output stage and also resulted from the decrease of their output conductances. After long-term stress, the amplifier became unstable. The reason might be that its phase margin was reduced due to hot carrier effect.

Double cropping system including paddy fieldsoybean is widely adopted nationwide, due to rise in marketprice and its higher income than paddy field rice. Sowingdate of soybean as a second crop is being delayed dependingon first crop’s growth period and harvesting time. Due tothe increased temperature in October and delayed first frostdate, soybean could be harvested without frost damage evenin late-plating. Therefore, selection of soybean cultivar whichis appropriate for this environment is very important. Theeffect of sowing date and genotype of soybean on growthand yield was investigated for three planting dates (June20, July 5, and July 20) with ten cultivars developed forsoy-pate production, to figure out plant development andyield pattern in delayed planting. As planting date is delayed,plant height and pod number was decreased and this patternwas more clearly detected in mid-late maturity cultivars. Hundred-seed weight did not show significant changes evenin late planting, due to compensations between yield components. Yield reduction of July 20 in contrast to that of June 20showed that Nampung (9.6%) showed the least yield decline. Maximum yield was achieved from Daepung, Taekwang,and Uram among other soybean cultivars in late planting. Shortening of growth period was strongly detected in reproductivestage while length of vegetative stage was regularlymaintained in both early and mid-late maturity cultivars

A myeloid sarcoma (MS) is an extramedullary tumor consisting of primitive granulocytic precursor cells. Although most such tumors have been reported in patients with acute myelogenous leukemia, MS is rarely recognized as an isolated tumor without any evidence of leukemia. However, in such cases, the initial diagnosis of MS can be difficult, so initial misdiagnosis rates of up to 75% have been reported. This report describes an unusual case of MS in a 3-year 5-month-old girl presenting as bilateral renal enlargements, and brain masses, with multiple bone involvements, but no hematological abnormalities.

우리는 참부모님을 ‘아버지’라고 생각하고 있으며 말의 표현 역시 ‘아버지’라 부르며 식구들끼리,친구들끼리 이야기를 주고 받는다.그럼 아버지란 존재가 무엇인가를 놓고 생각해 보면,나를 있게 만들어주신 분이다.우리는 우리의 아버지가 어떠한 분이고,어떤 목적을 가지고 사시는 분이며,어떤 인생노정을 사신 분인지 그분의 실체적 삶을 통해서 어렴풋이 알고 있다.자식된 도리로서 아버지께서 세우신 업적 중 최고의 업적은 무엇이냐고 질문을 하면 정확하게 딱 집어서 말할 수 있는 통일가의 자녀들이 얼마나 있을까?
