연구배경 : 정신분열병 환자들은 인지장애를 보이는바, 저자들은 이들을 대상으로 한국형 인지분화훈련 프로그램을 개발하여 정신분열병 환자들을 대상으로 인지재활훈련을 실시한 후 환자들의 인지기능, 정신병리 및 문제해결기술에 미치는 효과를 조사하였다. 방 법 : 28명의 정신분열병 환자를 훈련군(n=14)과 대조군(n=14)으로 나누어 훈련군에게 한국형 인지분화훈련 프로그램을 1회 60분씩, 주당 2회씩, 11주간 총 22회를 실시하였다. 환자들의 인지기능은 K-WAIS의 산수, 빠진곳찾기, 어휘, 공통점찾기 소검사로 측정하였고 정신병리는 양성 및 음성증상 척도로 측정하였으며 문제해결기술은 사회문제해결척도로 평가하였다. 인지재활훈련의 효과를 평가하기 위해 훈련 전후의 인지기능, 정신병리 및 문제해결기술의 변화를 종속변수로 하고 훈련 유무를 독립변수로 하여 반복측정에 의한 변량분석으로 자료를 분석하였다. 결 과 : 한국형 인지분화훈련이 시간에 따른 인지기능검사 중 산수 소검사, 문제해결기술 중 시회문제해결척도의 전체 점수와 문제해결기술 소척도의 점수의 변화에 유의한 영향을 미쳤으나, 시각적 주의력, 개념화 능력 및 정신병리의 점수의 변화에 유의한 영향을 미치지 않았다. 결 론 : 한국형 인지분화훈련 프로그램은 정신분열병 환자에서 청각적 주의력 및 문제해결기술의 호전을 꾀할 가능성이 있음을 시사한다. Objectives : The purpose of this study was to investigate the effects of cognitive differentiation training program- Korean version(a training program of attention and conceptual abilities) on cognitive function, psychopathology and problem solving skills in patients with schizophrenia. Methods : A total of patients diagnosed as schizophrenia using DSM-Ⅳ were randomly assigned to 2 groups. The training group went through a total of 22 sessions of cognitive differentiation training(60 min/ session×2 sessions/wk×11 wks). The attention-placebo control group received psychoeducation program during the same period. Arithmetic, vocabulary, similarities, picture completion of Wechsler Adult Intelligence Scale-Korean version, Positive and Negative Syndrome Scale, and Social Problem Solving Scales were administered to all patients, both before and after the training program. Results : In the arithmetic scores(F=6.35, af=1, p=0.018) of Wechsler Adult Intelligence Scale-Korean version, and total scores(F=6.35, af=1, p=0.018) and problem solving skill scale scores(F=4.88, af=1, p=0.036) of social problem solving scale, interaction effects of training was significant. Conclusion : Our findings suggest that cognitive differentiation training program-Korean version is effective on improving auditory attention and problem solving skills in patients with schizophrenia.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

The characteristics of mixed-firing an anthracite and a bituminous coal were studied in a fluidized bed combustor(0.55m-I.D., 2.2m-hight). The elutriation rate, the pressure fluctuation properties and composition of flue gas were measured to interpret the combustion characteristics in a fluidized bed combustor of uniform or multi-sized particles of mixed anthracite and bituminous coal. That result have been compared with the particle size distribution, anthracite mixing fraction and excess air. The combustion characteristic of mixed fuels in a fluidized bed combustor could be interpreted by using standard deviation of pressure fluctuation, major frequency and power spectrum density function.

The current induced on a perfectly conducting strip excited by incident fields which are transverse magnetic (TM) wave or transverse electric (TE) wave to the strip axis are solved by three methods. The one is analytic and the others are numerical method: SIT (Spectral Iteration Technique), CGFFT (Conjugate Gradient Fast Fourier Transform). It is estimated accuracy of current values, as that are compared results of the analytic method with that of the numerical methods. The procedure involves the incorporation of subdmain basis functions associated with the current representation of a conducting strip. It is shown that significant improvements are achieved in the convergences of the CGFFT method when using sinc basis functions.

Numerical simulation is performed by the commercial code FLUENT for individual air condition system to calculate the velocity and temperature profiles around worker in climate room. The main calculation region is the space of ㄱ shape between wall and worker in the individual air condition system. The fresh air is emitted from 3 inlet attached on the right, left and center wall. Because the comfort of worker is closely related with the velocity and temperature of wind, these data are key role for design of the individual air condition system. This work is previous study for evaluation of thermal comfort of workers in room without much experiments according to metabolism and heat emission of human body. Numerical simulation results are as followings, 1. There is an possibility of the thermal comfort of worker is gotten worse due to the presence of dramatic change of wind velocity around worker. 2. Temperature gap exists in worker's body between top and bottom according to fresh air inlet velocity and position which is right, left and center of wall. 3. Calculation results of the skin temperature of worker are key data for evaluation of thermal comfort with experimental data in climate room. 4. Optimum condition of temperature, direction and velocity of fresh air will be obtain by numerical simulation for energy effective individual air condition system.

This study was intended to evaluate condyle position and the relationship of condyle position change and post surgical relapse following the sagittal split ramus osteotomy for mandible setback in 25 patients by paired t-test and multiple regression analysis. We used oblique transcranial and cephalometric radiographs taken before operation, immediate after operation, and at least 6 months post operatively. 1. In oblique transcranial view, posterior joint space was decreased immediate after operation and increased 6 months after operation. To compare the measurement before and 6 months after operation, there was no statistically significant change in over all joint spaces(P>0.05). 2. The joint spaces changed under the 0.2mm were 30%, 0.2mm to 1.0mm were 60.7%, above 1.0mm were 9.3%. This result reveals that condyle position was relatively reproduced to pre-operative state. 3. Statistically, the amount of mandible set back didn't influence the post operative relapse(P>0.05). 4. Statistically, the amount of mandible set back didn't influence the condylar displacement(P>0.05), and the amount of joint space change didn't influence the post operative relapse.(P>0.05) The changes in joint space is in the standard tracing error or within the adaptive capacity of the individual, it was too small to influence the stability of surgery.

Adaptive blind equalizer has gained wide-spread use in communication receivers that operate without training signals. In this paper, in order to reduce the residual error and speed up the convergence process simultaneously, we propose a new blind equalizer operating on dual mode which has decision regions. Therefore, it has both a good initial convergence of the Sign-Godard algorithm and a low residual error of the radius-directed algorithm after converging. High order statistics are used for blind phase recovery and for avoiding local minima. Simulation results show that the new algorithm has a faster convergence rate in comparison to conventional algorithms. In additon, it has a lower residual error than that of conventional algorithms.

The study was to investigate the difference of the total sweat rate, local sweat and skin temperature according to environments during submaximal exercise. For this, eight male field hockey athletes were made to take bicycle exercise of 40% Vo₂max for 60min. The environmental conditions were divided into four groups ; Environment Ⅰ (Temperature 18℃, Relative Humidity 40%). Environment Ⅱ (Temperature 18℃, Relative Humidity 70%). Environment Ⅲ (Temperature 30℃, Relative humidity 40%). Environment Ⅳ (Temperature 30℃, Relative Humidity 70%). Local sweat rate, rectal temperature and main skin temperature were recorded every 10 minutes by thermister, total sweat rate measured by the weight loss during the exercise. Local sweat rate according to environments during submaximal exercise increased mainly by relative humidity. The other local skin temperature and the rising-rate of body temperature had an effect on it. Total sweat rate according to environments during submaximal exercise was more influenced by hot-high humidity rather than by temperature especially led to the 1,400g's weight loss during the one hour exercise. Local skin temperature according to environments during submaximal exercise was significantly differentiated by temperature and humidity as well as by time. Mean skin temperature according to environments during submaximal exercise was varied, up-and-down repeatedly. No relationships between rectal temperature or local skin temperature and total sweat rate or local sweat rate but these factors were partly interrelated. To conclude, total sweat rate was influenced most by humidity and local sweat rate differed according to local skin temperature and the rising-rate of body temperature.
