[[alternative]]An Investigative Research of Role Expectation and Role Performance of the Elementary School Resource room Teacher
[[abstract]]The aim of this research is to explore and discuss both the school staff's role expectation of the resource room teachers, and the latter's own assessments of their role expectations and performances, including consideration of hindrance factors. First the researcher use a form of questionnaire-The Elementary School Resource Room Teacher Role Function Scale to investigate the above-mentioned attitudes to role expectations and performances. Then, the researcher uses The Resource Room Teacher's Interview Outline (again, a kind of questionnaire which is in a semi-structured interview form) in order to understand and analyze the difficulties and problems that the resource room teachers face as they perform their roles in their daily teaching jobs. The main findings of this study will be discusses and elaborated upon as follows:
1.The study shows that there exist differences among the school staff's role expectations of the resource room teachers. The expectation in the category of consultation of the performances of the administrators and classroom teachers is higher than that of the performance of the resource room teachers; whereas the expectation in administration operation of the administrators is higher than that of the classroom teachers and the resource room teachers. The outcome reveals that communication between the resource room teachers and the school staff needs some push, especially in the consultation role performance area.
2.On discussing the resource room teachers' role performance, we may find that a higher performance level exists in the areas of teaching and assessment, whereas, there is a lower performance level in the consultation role. Owing to this, we may understand that the resource room teachers' skill lie mainly in teaching and assessment, and that they are not so adequate in fulfilling their consultation role.
3.In the analysis of four different personal background of resource room teachers, we find that role expectations of the female teachers are higher than that of the male teachers. The resource room teachers between 41 and 50 years old are superior to those whose ages are below 30 in role performances: i.e. in terms of assessment, teaching, consultation, and public relationships. The resource room teachers who have taken 20 credits in special education have better role performances than those who have not taken 20 special education credits.
4.There is a remarkable gap between the resource room teachers' role expectation and performance. The role expectation is significantly larger than the role performance in five job functions of the role resource teachers. In the 27 items, there are 24 items in role performance being lower. than role expectation. This indicates that the resource room teachers fail to achieve their goals, in the sense that their actual performances do not match their role expectations.
5.The major factors that cause this are as follows: A) Too many teaching hours; B) Lack of professional training of the resource room teachers; C) Classroom teachers being too busy in class affairs; D) Lack of parental cooperation; E)Lack of support from the administrators.
This study not only discusses the findings of the research but also reaches conclusions which provide the resource room teachers, the educational administration authorities, and the teacher training units with suggestions.

[[abstract]]病毒潛伏感染是一個重要的醫農學問題,要研究病毒潛伏感染,首先要瞭
解病毒DNA在寄主基因體的物理狀態,例如病毒大小、結構,以及病毒DNA
是否插入寄主細胞的基因體中。本實驗首先利用斑點雜合法以Hz-1標準病
毒DNA合成探針,偵測各Hz-1病毒潛伏感染細胞株中病毒的含量,發現在潛
伏感染細胞株TNPC1 中約含有12%的病毒DNA,TNPC2細胞約有0.8%的病毒DN
,TNPC3細胞約有16.4%病毒DNA,SFP2、SFP4細胞則各有少於0.1%及0.4%的
病毒DNA存在,1983年Burand等人發現干擾粒子(Defective interfering
particles)可能為病毒建立與維繫潛伏感染時所必需。因此,第二部份的
驗利用Southern雜合方法來分析標準病毒DNA和干擾粒子DNA在潛伏感染細
胞中存在的比例,結果發現標準病毒DNA和干擾粒子DNA同時存在於潛伏感
染的細胞中。第三部份是研究Hz-1桿狀病毒DNA是否插入寄主基因體中。由
於病毒DNA很大,一般電泳方法無法分析,因此利用pulse field gel elec
trophoresis(PFGE)來解決這個問題。結果顯示病毒DNA以插入寄主染色體
中或以環狀DNA的方式存在於潛伏感染細胞中。第四部份是潛伏感染細胞對
Hz-1病毒干擾(viral interference)的試驗,結果發現TNPC1、TNPC2、TNP
C3、SFP2、SFP4等Hz-1病毒潛伏感染細胞株對Hz-1病毒均有同質干擾的情
形。其中SFP2、SFP4是以細胞自戕(apoptosis)的方式來表現,TNPC1、TNP
C2、TNPC3則否。第五部份是比較各Hz-1病毒潛伏感染細胞株潛伏特異性基
因hem-1的表現情形,這五種潛伏感染細胞株均會表現hem-1基因產生轉錄
子PAT-1,不過表現強度相差很大,依次是TNPC1強於TNPC3,TNPC3強於TNP
C2;SFP2、SFP4相差不多,TNPC1、TNPC2、TNPC3潛伏感染細胞株表現hem-
1基因的情形均遠強於SFP2、SFP4潛伏感染細胞株。最後一部份的實驗與病
毒自潛伏感染細胞中的復發(reactivation)有關。利用已建立好的Hz-1病
毒潛伏感染細胞株,試驗以飢餓(低血清)、TPA(一種病毒復發誘引劑),以
及低、高溫處理,檢看Hz-1病毒復發的情形。結果顯示,TNPC2的細胞株在
任何一種處理之下均有病毒復發的情形,其餘細胞株則否。

[[abstract]]The purpose of this research is to investigate the role of vision in balance training for students with mental retardation. The subjects included 8 students ranging from 13 to 15 years of age. Before training, each subject had to be examined with the following tests under full-vision and no-vision condition walking forward and backward on the balance beam. After pre-test, each subject was assigned to a vision or no-vision training group. Each group had 5 days training session with balance beam walking and trendmill walking. The mid-test and final-test was held on the 3rd and 7th day after the training had started. Testing items included the distance, the speed and the step distance. The conclusion is as following: 1.After training, the full-vision and no-vision group shows significant differences in distance, it is the evidence that balance performance could be improved after physical training. 2.No-vision group took slower and steady walking strategy and the full-vision group relied on vision and use the fast but unstable movement strategy. 3.Walking backward with full-vision, walking forward with no-vision, walking backward with no-vision are effect by vision condition. No-vision group take slower and shooter step of distance. 4.No-vision training seems help students improving their movement stability. It is an inexpensive and easy way to practice under different visual conditions. Hopefully more researches and teaching strategies of this kind will be done in the future.

[[alternative]]THE ROLE OF ATTENTIONAL FOCUS DIRECTION IN MOTOR LEARNING STRATEGY OF DISCRETE MOVEMENT
[[abstract]]The purpose of this study was to investigate the effects of direction within attentional focus on learning a motor task of ball throwing accuracy. By novelty principle, participants had to sit on a chair and throw balls with their non-dominant hand. Thirty university students who had no previous experience of the task were randomly assigned to one of the following three groups: (1) external direction of attentional focus group; (2) internal direction of attentional focus group; and (3) mixed direction of attentional focus group. Experimental trials included 10 trials for pretest to test the homogeneity of participants, 120 trials for acquisition, 15 trials for both 10-minute immediate retention test and one-day delay retention test. Other than radial error (RE), variable error (VE) and motor performance error rate (MPER) as dependent variables, questionnaires were administered to insight about participants’ perception during experiment. The experimental data were transformed into scores of proportion of dependent variables. Mixed Two-way ANOVA and Tukey’s HSD method were used for statistical analysis. Findings were as follows: (1) within the whole new discrete motor skill acquisition, the strategy of external direction of attentional focus was better than strategy of internal direction of attentional focus, especially for accuracy of task performance and motor performance error rate; (2) the strategy of mixed direction of attentional focus was better than strategy of internal direction of attentional focus, especially for motor performance error rate; and (3) based on the radial error, different direction of attentional focus was thought to be a learning variables, whereas based on the motor performance error rate, various direction of attentional focus was thought to be a performance variables.
Enhancing the damping properties of cement mortar by pretreating coconut fibers for weakened interfaces
Pretreated coconut fibers can be applied as renewable damping components in fiber-reinforced cement mortars to reduce the adverse effects of vibration and promote the recycling of waste fibers. In this study, FT-IR, TG, XRD, and SEM measurements were performed to analyze the morphologies and physicochemical properties of the coconut fibers before and after pretreatment. The compressive strength, porosity, and damping properties were tested to study the effects of fiber pre-treatment on the mechanical properties of cement mortar. In contrast to original fibers, pretreated coconut fibers induced a moderate air-entraining effect in cement mortars. Therefore, the mortars with pretreated fibers exhibited significantly lower strength loss, indicating consistency with the porosity results. Furthermore, by adding 0.75 vol% coconut fibers pretreated by a mixed solution of NaOH and H2O2, the loss tangent of the cement mortar can be increased by 25%. The enhanced damping properties were attributed to the weakened interface between the fibers and cement mortar matrix, which facilitated dissipation of the vibration energy. Moreover, a simplified shear-lag model was proposed to describe the relationship between the weakened interface frictional sliding and the damping properties of the cement mortars.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen
Investigation of the hydration properties of cement with EDTA by alternative current impedance spectroscopy
Alternative current impedance spectroscopy (ACIS) is a promising non-destructive testing method to monitor long-term change and assess the durability of concrete. This study investigates the influences of Ethylene Diamine Tetraacetic Acid (EDTA) on the hydration of hardening cement by ACIS. It is found that EDTA retards the early-age hydration of cement but can facilitate the later age reaction. Pastes with EDTA show comparable or higher compressive strength than Control at 28 d, especially when the dosage is higher than 0.4%. Microstructural characterization results reveal the working mechanism of EDTA originating from its complexing effect on free ions. The resistivity evolution of the pastes detected by ACIS can well reflect the effects of EDTA on the cement hydration in different ages. Proportional relations are identified between the resistivity and other hydration parameters, such as reaction degree, chemical shrinkage, compressive strength. The results of this study indicate a wider prospect of ACIS in monitoring the microstructure evolution and macro-properties of cementitious materials.Materials and Environmen
Recycling of ferronickel slag tailing in cementitious materials: Activation and performance
As an industrial by-product containing pozzolanic components, recycled ferronickel slag (FNS) has the potential to be supplementary cementitious materials (SCMs) to reduce the massive carbon footprint of the cement industry, however, the main limitation of ferronickel slag as SCMs is the low hydration rate at an early age. In this study, the pozzolanic activity property results indicate that if the proportion is more than 10 %, FSN can hardly participate in the cement hydration reaction during the early stage, even the mechanical strength of FNS-mortar decreases obviously with the higher proportion of ferronickel slag. Therefore, mechanical grinding and steam curing at an early age are applied to promote the reaction activity of the recycled ferronickel slag tailing in this study. Compared with standard curing, the compressive strength of hardened FNS-cement paste with steam curing at 60 °C or 80 °C increased by 8.2 % or 33.8 %, and the connected porosity decreased by 18.9 % or 17.3 %. And MgO in the ferronickel slag exists as Mg2SiO4 in raw materials and enters the C-S-H gel with the formation of M-S-H gel during the secondary hydration stage. This study provides a theoretical basis for solid waste-based concrete and promotes the recycling, conservation, and resources of solid waste in building materials.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen
Nondestructive Monitoring Hydration of Belite Calcium Sulfoaluminate Cement by EIS Measurement
In this study, the impact of water-to-cement (w/c) ratios of belite calcium sulfoaluminate cement (BCSA) on the hydration kinetics and the electrochemical impedance spectroscopy (EIS) parameters is studied. According to the analysis of classic hydration measurements, such as calorimetry tests, chemical shrinkage content, and chemically bound water content, it can be concluded that a higher w/c ratio clearly accelerates the hydration of BCSA cement paste. The electrical resistivity of BCSA0.35 cement paste is more than 4.5 times that of BCSA0.45 and BCSA0.5, due to the gradually densified micropore structure blocking the electrical signal transmission rather than the free charged-ion content. The porosity of BCSA0.5 is 27.5% higher than that of BCSA0.35 and 7.8% higher than that of BCSA0.45, which proves the resistivity is clearly related to the variation in microstructure, especially for the porosity and pore size distribution. The novelty of this study is the linear regression with logarithm terms of electrical resistivity and classic hydration parameters such as chemical shrinkage, cumulative hydration heat, and chemically bound water is established to extend the classical expression of cement hydration degree. It indicates that the electrochemical impedance spectroscopy can be taken as a nondestructive testing measurement to real-time monitor the cement hydration process of cement-based materials.Materials and Environmen
