This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

비선형 공정을 위한 FCM 클러스터링 알고리즘 기반 퍼지 추론 시스템

본 논문에서는 비선형 공정을 퍼지 모델링하기 위해 FCM 클러스터링 알고리즘을 기반으로 하는 퍼지 추론 시스템을 소개한다. 비선형 공정에 대한 퍼지 규칙의 생성은 일반적으로 차원이 증가할수록 규칙의 수가 지수적으로 증가하는 문제를 가지고 있다. 이를 해결하기 위해, FCM 클러스터링 알고리즘을 이용하여 입력 공간을 분산 형태로 분할함으로써 퍼지 모델의 규칙을 생성한다. 퍼지 규칙의 전반부 파라미터는 FCM 클러스터링 알고리즘에 의한 소속행렬로 결정된다. 퍼지 규칙의 후반부는 다항식 함수의 형태로 표현되며, 각 규칙의 후반부 파라미터들은 표준 최소자승법에 의해 동정된다. 마지막으로, 비선형 공정의 특성 및 성능을 평가하기 위하여 비선형 공정으로는 널리 이용되는 데이터를 이용한다. In this paper, we introduce a fuzzy inference systems based on fuzzy c-means clustering algorithm for fuzzy modeling of nonlinear process. Typically, the generation of fuzzy rules for nonlinear processes have the problem that the number of fuzzy rules exponentially increases. To solve this problem, the fuzzy rules of fuzzy model are generated by partitioning the input space in the scatter form using FCM clustering algorithm. The premise parameters of the fuzzy rules are determined by membership matrix by means of FCM clustering algorithm. The consequence part of the rules is expressed in the form of polynomial functions and the coefficient parameters of each rule are determined by the standard least-squares method. And lastly, we evaluate the performance and the nonlinear characteristics using the data widely used in nonlinear process.

An ameloblastoma is one of the most common odontogenic tumors. Ameloblastoma is cytologically a benign tumor, but is clinically characterized by infiltrative growth and high recurrency. The treatment of ameloblastoma has been controversial. The aim of this paper is to consider effectiveness of curettage and enucleation after SSRO in the small-sized multilocular intraosseous ameloblastomas that have been treated more frequently by radical treatment. They were radiographically characterized by the cortical bone that was expanded or eroded locally and histopathologically by solid multilocular ameloblastomas. It is considered that curettage and enucleation after SSRO and long-term follow-up enable the small-sized multilocular intraosseous ameloblastomas that were characterized by almost destroyed cancellous bone and expanded cortical bone to treat minimizing facial disfigurement and masticatory dysfunction and sociopsychological impact produced by radical treatment. We recommend that the small-sized multilocular intraosseous ameloblastomas without involvement to the surrounding soft tissues be first treated by curettage and enucleation after SSRO.

A Clinical review on 306 patients with bacteremia and septic shock among 72,961 inpatients admitted to Severance Hospital from January 1981 to August 1984 was done and the results were as the follows: 1) The incidence of bacteremia was 0.42%. 2) The mortality of the total bacteremia was 24.8%; that of bactermia without shock was 15.2% and that of septic shock was 51.2%. 3) Incidence of bacteremia and septic shock per 1,000 patients was 4.1 in 16~30 age group, 5.9 in 31~45 age group, 9.6 in 46~60 age group and 7.1 in age older than 61 group. 4) Underlying diseases frequently encountered at each age group were hematologic malignancy in 16~30 age group, hepatobiliary diseases in 31~45 age group, hepatobiliary diseases and cancer in 46~60 age group and respiratory diseases in age over 61 group. 5) The site of origin of the bacteremia could not be identified in 32% of the patients and among those patients in whom the site of bacteremia could be determined, the urinary tract and skin were the most frequent site of origin followed by respitatory tract, biliary tract, gastrointestinal tract and others, in this order. 6) The number of bacteremia and septic shock caused by Gram negative bacteria was 132 and 59, mortality 10.9% and 55.9%, respectively. The number of bacteremia and septic shock caused by Gram positive bacteria was 58 and 13, mortality 6.9% and 38.5%, respectively 7) There was significant relation between etiologic organism and site of origin of bacteremia. 8) There was significant relation between underlying disease and mortality. 9) There was high mortality(74.1%) in patient with elevated anion gap over 20 mmol/L

Purpose: To evaluate the properties of antibiotic and NSAIDs administration before extract of the impacted mandibular third molar. Materials & Methods: No patient showed any sign of pain, inflammation, or swelling at the time of removal. A group of 50 patients was classified in Group 1(preemptive and oral medication was carried out for 3 days postoperatively, N=23) and Group 2(oral medication was carried out for 3 days postoperatively, N=27) subgroups. Clinical and radiologic factors were recorded for each case, and the rationale for assigning the patients to the groups was strictly random. The surgical technique was the same in all cases, and the follow-up period was 1 week. Parameters that were evaluated were infection, swelling, pain and differences in mouth opening. Results: We could not find any significant difference between the 2 groups regarding the evaluated parameters. Conclusion: The results of our study show that antibiotic and NSAIDs administration before the removal of lower third molars does not contribute to a decrease infection, swelling, pain or increase mouth opening. Therefore antibiotic and NSAIDs administration before the removal of lower third molars is not recommended for routine use.
