최근 몇 년 회귀 주류와의 융합 교육 정책 하에 대만의 특수 교육 학교는 예전과 다른 큰 변화에 직면해 있다. 완전 융합 이념의 실시 또 심신장애학생을 주류교육으로 회귀해야 한다는 것을 제창함으로, 특수교육학교는 인원이 감소하게 됐다. 특수교육 학교는 신입생 모집이 부족한 상황에서 학교 교사들의 관점이 교장의 지도에 대해 보는 관점이 어떻게 다른가? 그에 대한 요구도 다른가? 본 연구는 두 인자 변의 수 분석이 대만 지능 장애와 감각 장애 종류의 특수 교육 학교 교장전형 리더십에 대한 연구이다. 실험 대상자는 8개 지능 장애종류 특수교육 학교와 5개 감각 장애종류 특수 교육 학교의 259명의 교사이고 그들이 특수교육학교 교장 리더에 대한 건의를 제출했다. In recent years, the domestic special education schools have faced with huge changes under the mainstream and inclusive education policies for the implementation of the full-inclusive and the mainstream education for the students with impairment. That causes the special education schools to reduce classes. Under this situation, what are the teachers?fdifferent views about the principal? What are their needs? The study was undertaken through two-way ANOVA to explore principals?ftransformational leadership between the schools for the mentally retarded and for the sensory impaired. 259 teachers were selected from 8 schools for the mentally retarded and 5 sensory impairment special education schools. Based upon the findings, the implications for practice were proposed.

Basal stem rot incidence caused by a white-rot fungus, Ganoderma boninense, is the major disease of oil palm in Southeast Asia. The rate of disease transmission and host damage are affected by variations in pathogen aggressiveness. Several other studies have used the disease severity index (DSI) to determine G. boninense aggressiveness levels while verifying disease using a culture-based method, which might not provide accurate results or be feasible in all cases. To differentiate G. boninense aggressiveness, we employed the DSI and vegetative growth measurement of infected oil palm seedlings. Disease confirmation was performed through scanning electron microscopy and molecular identification of fungal DNA from both infected tissue and fungi isolated from Ganoderma selective medium. Two-month-old oil palm seedlings were artificially inoculated with G. boninense isolates (2, 4A, 5A, 5B, and 7A) sampled from Miri (Lambir) and Mukah (Sungai Meris and Sungai Liuk), Sarawak. The isolates were categorized into three groups: highly aggressive (4A and 5B), moderately aggressive (5A and 7A), and less aggressive (2). Isolate 5B was identified as the most aggressive, and it was the only one to result in seedling mortality. Out of the five vegetative growth parameters measured, only the bole size between treatments was not affected. The integration of both conventional and molecular approaches in disease confirmation allows for precise detection.

Objective: Endoscopic approaches to the craniovertebral junction (CVJ) have been established as viable and effective surgical treatments in the past decade. One of the major complications is leakage of the cerebrospinal fluid (CSF). This study aimed to investigate the efficacy and feasibility of suture closure at the nasopharyngeal mucosa upon durotomy. Methods: A series of consecutive patients who underwent different endoscopic approaches to the CVJ were retrospectively reviewed. The pathologies, surgical corridors, neurological and functional outcomes, radiological evaluations, and complications were analyzed. Different strategies of repair for the intraoperative CSF leakage were described and compared. Results: A total of 22 patients covering 13 years were analyzed. There were 12, 2, and 8 patients who underwent transnasal, transoral, and combined approaches, respectively. There were 8 patients (36.4%) who experienced intraoperative CSF leakage, and were grouped into 2: 4 in the nonsuture (NS) group and 4 in the suture-repaired (SR) group. The NS group had 3 (75%) persistent CSF leakages postoperation that caused 1 mortality, whereas patients of the SR group had only 1 minor CSF rhinorrhea that healed spontaneously within days. Conclusion: In this series of 22 patients who required anterior endoscopic resection of pathologies at the CVJ, there was 1 (4.5%) serious complication related to CSF leakage. For patients who had no durotomy, the mucosal incision at the nasopharynx usually healed rapidly and there were few procedure-related complications. For patients with intraoperative CSF leakage, suture closure was technically challenging but could significantly lower the risks of postoperative complications.

Numerical study of ventilated cavitating flows with free surface effects

Mei-Shan Jin,Cong-Tu Ha,박원규 대한기계학회 2013 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.27 No.12

Cavitating flow is usually formed on the surface of a high-speed underwater object. When the object moves near the free surface athigh speed, the cavitation signature becomes a main factor to be overcome by the sensors of a military satellite. This paper studies thefree surface effect on the ventilated cavitation process. The governing equations are Navier-Stokes equations based on a homogeneousmixture model. The multiphase flow solver used here relies on an implicit preconditioning scheme in curvilinear coordinates. The cavitationmodel used is a new cavitation model developed by Merkle et al. (2006). Computations of free surface effects were carried out witha NACA0012 hydrofoil to enable comparisons with experimental data presented in the literature. Calculations were then performed consideringthe ventilated cavitation process, including the effect of a noncondensable gas with free surface effect.

<P><B>Abstract</B></P> <P>A numerical study on heat transfer effects of cavitating and flashing flows was conducted by employing a compressible homogeneous mixture approach. A dual-time preconditioned method was applied to enhance the efficiency and accuracy of the computations under various flow conditions. A sensitivity analysis of the empirical coefficients used to access the predictive capability of the existing mass transfer models was assessed for cavitating flows in a converging-diverging nozzle. To confirm the use of the calibrated empirical coefficients, computations of the water flows over a cylindrical head form and a Clark-Y hydrofoil were then carried out. The results obtained indicate an overall good agreement with the experimental data. Finally, the thermal effects on the phase change process were confirmed through an examination of a flashing flow along with thermo-fluid flows. The predicted results also show a good agreement with the experimental data. In conclusion, the existing system was shown to be effective in quantitatively predicting the thermal effects of the phase change processes, and can be used to examine the hydro- and thermodynamics of multiphase flows.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A numerical study of cavitating and flashing flows was conducted by employing a compressible homogeneous mixture approach. </LI> <LI> The system dominates pressure-driven vaporization and temperature-driven vaporization together. </LI> <LI> Phase change model’s dependency of model coefficients is assessed. </LI> <LI> The influence of thermal effects on evaporation process is proved by examining a flashing flow. </LI> </UL> </P>

Deqiang You,Mei Tu,Rong Zeng,Hao Liang,Weizhong Mai,Jianhao Zhao,Zhengang Zha 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.5

In order to improve the hemocompatibility of polyurethane (PU), we report a rapid and efficient two-step approach to graft poly(ethylene glycol) (PEG) onto PU surface by a microwave-assisted method,involving diphenylmethane diisocyanate (MDI) – functionalization and subsequent PEG coupling. Compared with conventional heating, the effects of solvent, time and MDI concentrations on the microwave-assisted MDI-functionalization, and the effect of time on the microwave-assisted PEG coupling were studied. PEGs with different molecular weights were successfully grafted onto PU surface under the optimum microwave-assisted conditions within only 20 min, and characterized by attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and chemical titration. The hydrophilicity and in vitro blood compatibility of the surfaces were evaluated by water contact angle measurements, blood coagulation time (whole blood clotting time and prothrombin time) and platelet adhesion tests, respectively. All the PU-PEG surfaces had improved surface wettability and hemocompatibility. The results suggested that microwave-assisted functionalization may be a promising method for rapidly and effectively decorating polyurethane surfaces.

Tsu-Chiang Tu,Shin-Nan Cheng,Jye-Daa Chen,Thau-Ming Cham,Mei-Ing Chung 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.2

Purpose: Hemophilia A (HA) is the most common X-linked inherited bleeding disorder. In some patients with HA, particularly those with severe HA, replacement therapy results in the production of high-responding clotting factor VIII inhibitors. The economic burden of this complication is the highest reported for a chronic disease. Our aim was to investigate the direct medical expenditure burden of high-responding inhibitors in patients with HA. Materials and Methods: A retrospective study was conducted using the National Health Insurance Research Database,utilizing data covering the period of 2004-2007. Results: In total, 638 males with HA¸ including 37 patients with high-responding inhibitors were evaluated. Over 99% of the annual median medical expenditure was attributable to the cost of clotting factor concentrates (CFCs) in patients with high-responding inhibitors. The annual median expenditure related to CFCs of the total medical care and outpatient care were US$170611 and US$141982, respectively, and were 4.6- and 4.3-fold higher in these patients during the study period, respectively. In patients with high-responding inhibitors, the median hospitalization expenditure and daily hospitalization cost with or without surgical procedures were 3.0- and 2.4-fold higher, respectively, and 4.3 and 5.6-fold higher, respectively. Conclusion: Our data reveal higher medical expenditures burden for patients with HA and high-responding inhibitors in Taiwan. Future research is encouraged to evaluate the impact of this burden on patient quality of life.

Purpose: Hemophilia A and B (HA, HB) are the most common X-linked inherited bleeding disorders. The introduction of factor concentrates has allowed for control of the lifelong chronic disease. However, no studies have been published regarding the epidemiology of hemophilia in Taiwan. Our aim was to determine the prevalence, incidence, and mortality rate, as well as trends in the use of factor concentrates,in individuals with hemophilia in Taiwan. Materials and Methods: A retrospective study was conducted using the National Health Insurance Research Database between 1997 and 2007. Results: We identified 988 males with hemophilia (HA : HB ratio=5.4 : 1). The mean prevalence per 100000 males was 6.7±0.1 for HA and 1.2±0.1 for HB. The estimated mean annual incidence per live male birth was 1 in 10752 for HA and 1 in 47619 for HB. Standardized mortality ratios for males with hemophilia (all severities) or severe hemophilia were 1.3- and 2.1-fold higher than that of the general male population, respectively. Mean factor VIII (FVIII) and factor IX (FIX) usage was 1.5003±0.4029 and 0.3126±0.0904 international units (IUs) per capita, respectively. Mean FVIII and FIX usage per patient with hemophilia (all severities) or severe hemophilia was 44027±11532 and 72341±17298, respectively, and 49407±13015 and 74369±18411 IUs per person with HA or HB, respectively. Conclusion: Our data revealed epidemiologic and factor concentrate usage trends in males with hemophilia in Taiwan, highlighting a need for improvements in the mandatory National Health Insurance registry. A better-designed, patient-centered registry system would enable more detailed patient information collection and analysis, improving subsequent care.
