Objectives : This study was to identify the relationship between quality of life and psychosocial characteristics in patients with schizophrenia. Methods : The subjects were eighty nine patients with schizophrenia according to DSM-IV. The Korean Quality of Life Scale (K-QLS) and the Korean modified Scale to measure Subjective Well-being under Neuroleptic treatment (KmSWN) were used to assess quality of life. The psychopathology of each patient was assessed by the Positive and Negative Syndrome Scale (PANSS). The Scale to Assess Unawareness of Mental Disorder (SAUMD) was used for differentiating presence and absence of insight. The Social and Occupational Functioning Assessment Scale (SOFAS), the Scale of Social Support (SSS), and the Family Adaptability and Cohesion Evaluation Scale (FACES) were used for assessing psychosocial characteristics. The correlation between the scores of each quality of life scale and other scales was examined, and multiple regression analysis was performed to assess the contribution of the scores of each quality of life scale to other scales. Results : The K-QLS score was significantly related to the scores of the PANSS, the SAUMD, the social conflict domain of the SSS, and the SOFAS. The KmSWN score was significantly related to the scores of the PANSS, the SOFAS, the social conflict domain of the SSS, and the FACES. In multiple regression analysis, the scores on the PANSS (32.9%), the SAUMD (5.8%), and the FACES (4.0%) were contributed to the score on the K-QLS, and the scores on the social conflict domain oftheSSS (17.3%) and the FACES (12.9%) were contributed to the score on the KmSWN. Conclusion : The relation between the K-QLS score and the scores of other scales means that the objective quality of life increases according to decreased the severity of symptom, the high level of insight and the socio-occupational function. And the relation between the KmSWN score and the scores of other scales means that the subjective quality of life increases according to the perceptions to the high level of social support, the low level of social conflict, and the high level of family adaptability and cohesion. The objective quality of life assessed by the K-QLS is affected primarily by the severity of symptoms, and the subjective quality of life assessed by the KmSWN is affected by the subjective perceptions of social conflict, family adaptation and cohesion. These findings suggest that the treatment of symptoms is important in the treatment of schizophrenic patients, but that it is also important to approach to the psychosocial characteristics to increase subjectivesatisfaction from the quality of life in them

The aim of this stady is develop the analytical model for the fluid flow characterstics at a pipe bends(90 degrees pipe bends and 60 degrees pipe bends) with Finite Element Method(FEM). In this study, the velocity potential function is defined as the fact that the negative of its derivative with respect to distance in any direction yields the velocity in that direction. Thus all practical flows must satisfy the Laplacian equation in terms of the velocity potential function. Therefore, the finite element method for the solution of the Laplacian equation is presented. The proposed analytical technique which deals with the potential flow is applied to the bend ofpipe, and which is computed to be velocity components for the finite element mesh. Form the results of this study , the velocity modulus for elements of corner region indicated the flow perturbation.

The DMA(Dimethylamine) gas sensors were fabricated with the ZnO-based thin films grown by a RF magnetron sputtering method. We investigated the sensitivity and response time according to temperature variation and DMA gas concentration. The ZnO-based thin film sensors sputtered in oxygen atmosphere showed higher sensitivity than those sputtered in argon atmosphere. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3) and V_(2)O_(5) and sputtered in oxygen atmosphere showed the maximum sensitivity of 218(working temperature, 250 ℃, DMA gas, 160 ppm) and speedy response time. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3), TiO_(2) and V_(2)O_(5), sputtered in oxygen atmosphere and aged at 330 ℃ showed the maximum sensitivity of 156(working temperature, 250 ℃, DMA gas, 160 ppm).

Numerous methods are available for estimating the peak flow required for design apllications in urban watersheds. Some incorporate the rainfall - runoff process, whereas others are completely empiric or correlative in that they predict peak flow by correlating the flow with simple drainage basin characterstic such as area or slpoe. In this study, the rational formula is identified as the most effective method of peak flow estimation for designing drainage facitities in urban watersheds.

A Sensitivity analysis on the model parameters involved in the O'Donnell model is made to demonstrate the effect of each parameter on the magnitude of daily runoff for small to medium sized watershed. In the structure of O'Donnell model, the sub-tank is installed in O'Donnell's model in rainfall-runoff process to give lag effect. This model uses three parameter calibration methods, trial & error method, Powell method and Rosenbrock method, in estimating parameters in order to estimate parameters of the model. And as a consequence of calibration, Rosenbrock method was most suitable among three methods. The O'Donnell type model is dealt with time variant system in which rainfall- runoff process of basin is indicated as API's function. Index of API's function is used to calibrate the infiltration coefficient(βi) and runoff coefficient (α2i) of the model. The calculated values of applied hydrologic system by O'Donnell type model are closer to observed values compared with SSARR model values.

Background : Despite substantial progress, the treatment of acute myeloid leukemia(AML) has produced complete remission in 60-80% of patients receiving induction chemotherapy, and median remission duration is about 12 months and only 20% to 35% of patients undergoing consolidation chemotherapy achieve long-term disease-free survival(DFS). We evaluated the long-term outcome of AML patients treated with doxorubicin/Ara-C/VP-16(DAV) induction chemotherapy and consolidation/intensification therapy. Method : Induction therapy : From January 1986 to December 1991, twenty three patients with previously untreated acute myelogenous leukemia received a course of 45mg/㎡ doxorubicin daily intravenously for three consecutive days with Ara-C at 100mg/㎡ by continuous intravenous infusion for eight consecutive days and VP-16 at 100mg/㎡ daily intravenously for three consecutive days. A second course of treatment was started if leukemia persisted on 22 days after treatment. Post-remission therapy : Three to six cycles were given at three or four months interval with Ara-C/doxorubicin/VP-16 regimen or other therapy. Results : Twenty two pateints were evaluable and complete remission was achieved in 16 of 22(73%). Median duration of complete remission was 8 months. The relapse rate was 81% and 63% relapsed in first year. 4-year survival rate of patients entering complete remission(n=16) was 19% and median survival duration was 14.5 months. The postremission chemotherapy was the only significant prognostic factor influencing long term disease free survival. No significant correlation was observed between the probability of survival and age (40< or >40), sex, FAR subgroup, and leukocyte count at diagnosis. The median survival duration were 21 months and 12.5 months for patients who received, or not received postremission chemotherapy respectively(P=0.035). Conclusion : Our results show that DAV combination chemotherapy is a useful therapeutic regimen in remission induction and postremission chemotherapy offering survival advantage in patients with AML entering complete remission.
