현재 의료진단, 화학공정의 모니터링이나 환경공학적 감시 및 제어 등의 분야에서 사용되고 있는 기존의 센서는 고가이며 용적이 클 뿐만 아니라 분석시간이 길고 사용하기 까다로운 것 등 여러 가지 문제점이 있다. 또한 측정환경에 영향을 주지 않을 만큼 충분히 작으며 빠른 분석시간을 가진 센서를 필요로 하고 있다. 본 연구에서는 기존의 센서들의 난점을 극복할 수 있는 새로운 형태의 FET형 전해질(electrolyte : H^+, K^+, Ca^2+, Na^+)분석 시스템, 용존가스(O_2, CO_2)분석 시스템의 개발을 중점적으로 추진하며, FET형 압력센서, 습도센서, 방사형 온도센서 등의 개별 FET형 센서에 관한 연구도 병행하고자 한다. Recently various kinds of sensors have been developed, being applicated to their own purpose. There are lots of difficulties to apply them to measurements in which the real-time monitoring is required without disturbing the surrounding environment. FET type semiconductor sensors, fabricated by the semiconductor integration technologies, have many advantages for their miniaturization, standardization, mass-production and in vivo/in situ monitoring. They also hold a very proper configuration for multi-functional sensors or integrated smart sensors, and wide availability by forming various kinds of physical or chemical sensing materials onto their sensing gates.

Background: Many chronic diseases are associated with the lifestyle such as smoking, alcohol drinking and exercise. Attention is increasingly paid on the effect of exercise for the management of chronic disease these days. Objective: The purpose of this study was to evaluate the status of the smoking habit, alcohol drinking and physical exercise of the patients with chronic diseases. Methods: Total 793 persons(normal:422, chronic disease patients:371) in a hospital were questioned regarding the habits of smoking and alcohol drinking, and a practice of physical exercise in 1999. The patients with chronic illness were divided into three groups(Group I included the patients of hypertension and diabetes mellitus. Group II includes respiratory disease and cancer. Group III included liver disease ). The rate of exercise, the rate of smoking cessation and the rate of abstinence were assessed. In logistic regression analysis with each independent variables in each disease groups(I, II and III), odds ratio for the presence of disease was controlled for age and education. Results: The rate of exercise, the rate of smoking cessation and the rate of abstinence was 31.5%, 27.3% and 9.5% in the patients with chronic disease, respectively. In control group, those were 31.5%, 21% and 2.1%, respectively. In logistic regression analysis with exercise as independent variable, odds ratios(95% CI) for age and education were significantly high, with smoking cessation, odds ratio for age was high and with abstinence, odds ratio for disease was high in all disease groups. Conclusion : It was suggested that an effort for proper changes of lifestyle related to disease such as smoking, alcohol drinking and exercise should be intervened in the patients with chronic diseases.

The purpose of this paper was to separate the copper and nickel ions from waste water using supported liquid membrane The effect of a given amount of carrier and ammonia concentration of up-stream was described. We used the LIX65N as carriers. The results were as follows 1. The distribution ratio of copper ions at equilibrium was shown linear increment according o the mole ratio of carrier concentration versus the concentration of metal ions increased to 2.0. The maximum distribution ratio of copper ions exceeded that of nickel by approximately 4-fold when the liquid membrane was saturated by carrier 2. The important parameters governing flux were carrier and ammonia concentration. We compared these two parameters, and then the latter influenced more than the former to get higher flux. The copper ions reacted with ammonia in the up-stream, it formed a complexes of Cu(NH₃)₄^(2+), and then diffused to interface of liquid membrane. 3. The flux of metal ions were increased with enlarging the distribution ratio of ordinary extraction. The principle of coupled transport was carried out by the difference of concentration of hydrogen ions. 4. We can be selectively separated in the mixing soultion of copper and nickel ions using LIX65N as carrier.

The process of ripening and senescence of tomato fruits has been studied in terms of storage temperature and pressure. Ribonucleic acid(RNA) content, Ribonuclease (RNase) activity, RNase properties and electrophoretic pattern of RNase were investigated during the storage. Total RNA content was decreased during ripening and senescence. The decreasing rate was greater at room temperature (R) than at low temperature (L), and under normal atmospheric pressure (NAP) than under sub-atmospheric pressure (SAP). RNase activity was increased during the period of climacteric rise and in accordance with developing color score. RNase activity was obviously higher at R than L, and under NAP than SAP. Consequently, RNase activity of NAP-R treatment was the highest among the treatments. The optimum temperature and pH of RNase activity were 70℃and pH 6.7, respectively. RNase activity was the most stable at pH 5.0 and retained 50% of its activity when treated at 90℃ for 10min. RNase activity was inhibited by cations and, markedly by zinc. Both treatment of NAP-R and SAP-L showed one band of RNase on gel electrophoresis in the early stage of storage. With the lapse of storage, the number of RNase band increased, showed 3 bands in the 7th day of NAP-R treatment and 2 bands in the 34th day of SAP-L treatment.

유상피성 육종은 매우 드문 악성 연조직 육종으로, 전형적인 경우들은 주로 젊은 남성의 수부, 전완부와 같은 신체의 원위부에 피하 혹은 심재성 피부 종괴로 발생하며, 조직학적 소견상 적은 비정형성을 나타내는 유상피성 세포와 방추형 세포의 증식에 의한 다발성 결절 형태의 배열을 보인다. 최근에 전형적인 유상피성 육종과 조직학적 유사성을 가지나 더 공격적인 형태인 proximal-type 유상피성 육종이 보고되었으며, proximal-type은 전형적인 유상피성 육종에 비하여 현저한 유상피성 세포의 발현과 매우 심한 비정형성을 나타내며, 세포가 매우 크고, 소포성 핵과 뚜렷한 핵소체를 보이며, 자주 rhabdoid 세포의 양상을 띈다. 임상적으로는 전형적인 형태에 비하여 호발 연령이 조금 늦고, 주로 체간부에, 특히 골반, 회음부, 생식기 등과 같은 심부에 발생하고, 더욱 공격적인 양상을 나타낸다. 저자들은 13세 소녀에서 원발부위를 알 수 없는, 골반내에 발생한 proximal-type 유상피성 육종 1예를 경험하여, 문헌 고찰과 함께 보고하는 바이다. Epithelioid sarcoma is a rare malignant soft-tissue sarcoma with an unknown histiogenesis, typically presenting as a subcutaneous or deep dermal mass lesion in the distal portions of the extremities of young adults. Recently, a more aggressive, so-called 'proximal-type' epithelioid sarcoma has been reported. In contrast to conventional epithelioid sarcoma, the proximal type is characterized by a predominantly large cell epithelioid cytomorphology, marked cytologic atypia, and frequent occurrence of rhabdoid features in most patients. Proximal-type epithelioid sarcoma has a predilection for appearing in the genitalia, especially the vulva, penis, pelvis and buttocks. Also this lesion appears to be somewhat more aggressive or at least metastasizes earlier than the conventional epithelioid sarcoma. We report a 13-year-old girl who presented with a buge mass filling the pelvic cavity which was painful, hard and fixed on palpation, and was radiologically diagnosed as a malignant germ cell tumors on the CT scan. The mass was surgically excised and pathologically proved to be an proximal-type epithelioid sarcoma of unknown origin.
