Full textAbstract:
The purpose of this study is to understand the principles of the “School of Tárrega”
by analyzing Tárrega’s thirty elementary-level studies and twenty-five intermediate- and
advanced- level studies according to books written by Pujol and Roch. Tárrega set the
modern sitting position based on the guitar of luthier Antonio Torres’, and two of Tárrega’s
outstanding pupils, Roch and Pujol, wrote three volumes of methods, which are the
foundations of the “School of Tárrega.” Therefore, the principles of the School of Tárrega,
such as sitting and playing positions, right- and left-hand playing positions, right- and lefthand
finger movements, and sound quality are first discussed in this study. Then, the fiftyfive
guitar studies are discussed and analyzed in groups according to their different technical
purposes, such as scale playing, arpeggio playing, blocked chords, barré technique, slur
technique, and special sound effects. When applicable, the modern technique will also be
visited and compared for understanding the similarities and differences between the modern
approach and the School of Tárrega.School of Music

Min, Ki-Bok. "Determination of equivalent hydraulic and mechanical properties of fractured rock masses using the distinct element method." Licentiate thesis, KTH, Land and Water Resources Engineering, 2002. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-1550.
Full textAbstract:
The equivalent continuum approach uses equivalent propertiesof rock mass as the input data for a continuum analysis. Thisis a common modeling method used in the field of rock mechanicsand hydrogeology. However, there are still unresolvedquestions; how can the equivalent properties be determined andis the equivalent continuum approach suitable for modeling thediscontinuous fractured rock mass.
The purpose of this paper is to establish a methodology todetermine the equivalent hydraulic and mechanical properties offractured rock masses by explicit representations of stochasticfracture systems, to investigate the scale-dependency of theproperties, and to investigate the conditions for theapplication of the equivalent continuum approach for thefractured rock masses. Geological data used for this study arefrom the site characterization of Sellafield, Cumbria, UK. Aprogram for the generation of stochastic Discrete FractureNetwork (DFN) is developed for the realization of fractureinformation and ten parent DFN models are constructed based onthe location, trace length, orientation and density offractures. Square models with the sizes varying from 0.25 m× 0.25 m to 10 m × 10 m are cut from the center ofthe each parent network to be used for the scale dependencyinvestigation. A series of the models in a parent network arerotated in 30 degrees interval to be used for investigation oftensor characteristic. The twodimensional distinct elementprogram, UDEC, was used to calculate the equivalentpermeability and compliance tensors based on generalizedDarcys law and general theory of anisotropic elasticity.Two criteria for the applicability of equivalent continuumapproach were established from the investigation: i) theexistence of properly defined REV (Representative ElementaryVolume) and ii) existence of the tensor in describing theconstitutive equation of fractured rock The equivalentcontinuum assumption cannot be accepted if any one of the abovetwo criteria is not met. Coefficient of variation and meanprediction error is suggested for the measures toquantitatively evaluate the errors involved in scale dependencyand tensor characteristic evaluation.
Equivalent permeability and mechanical properties (includingelastic modulus and Poissons ratios) determined onrealistic fracture network show that the presence of fracturehas a significant effect on the equivalent properties. Theresults of permeability, elastic moduli and Poisson's ratioshow that they narrow down with the increase of scale andmaintain constant range after a certain scales with someacceptable variation. Furthermore, Investigations of thepermeability tensor and compliance tensor in the rotated modelshow that their tensor characteristics are satisfied at acertain scale; this would indicate that the uses of theequivalent continuum approach is justified for the siteconsidered in this study.
The unique feature of the thesis is that it gives asystematic treatment of the homogenization and upscaling issuesfor the hydraulic and mechanical properties of fractured rockswith a unified approach. These developments established a firmfoundation for future application to large-scale performanceassessment of underground nuclear waste repository byequivalent continuum analysis.

Full textAbstract:
The purpose of this study was to investigate sixth grade students&rsquoconceptual and procedural knowledge and word problem solving skills in the domain of length, area, and volume measurement with respect to gender, previous mathematics achievement, and use of materials. Through the Conceptual Knowledge test (CKT), the Procedural Knowledge Test (PKT), and the Word Problems test (WPT) and the Student Questionnaire, the data were collected from 445 sixth grade students attending public schools located in four different main districts of Ankara. Both descriptive and inferential statistics techniques (MANOVA) were used for the data analysis. The results indicated that the students performed relatively poor in each test. The lowest mean scores were observed in the WPT, then CKT, and PKT respectively. The questions involving length measurement had higher mean scores than area and volume measurement questions in all tests. Additionally, the results highlighted a significant relationship not only between the tests but also between the domains of measurement with a strong and positive correlation. According to the findings, whereas the overall performances of students on the tests significantly differed according to previous mathematics achievement level, gender did not affect the students&rsquo
performance on the tests. Moreover, a wide range of mistakes were found from students&rsquo
written responses to the length, area, and volume questions in the tests. Besides, the results indicated that use of materials in teaching and learning measurement was quite seldom and either low or non-significant relationship between the use of materials and the students&rsquo
performance was observed.

The current environmental situation is a worrying scenario, making it inevitable to take different measures that result in solutions that overcome social and environmental challenges, pointing to a world of sustainable societies. As an important part of the complex and articulated group of necessary measures, education is essential, since it is capable of raising awareness that mobilizes people for social transformation. Environmental education is a practice that incorporates themes that are crucial in the society development in general and, if implemented in a critical, reflexive, transformative and emancipatory perspective, can increase the power of people action in this direction, favoring the challenging inflection, now in demand. In Brazil, this practice is referred to in concepts and principles known and established, which must be followed in its exercise, in projects and programs of community interaction, or in contents worked in the school environment. In this context, based on an evaluation of the National Curriculum Parameters of the Environment Transversal Theme and the National Curriculum Guidelines in Environmental Education, this paper defined four indicators for the analysis of the the São Paulo State official curriculum of the elementary education in relation to the approach to the environmental question: knowledge, participation, values, contextualization. Bibliographic review followed by documental analysis were the procedures used in the research, complemented by surveys of empirical researches to verify the occurrence of environmental education initiatives in the hidden curriculum in school practices. From the documental analysis of the Teacher's Notebook of all disciplines, we sought, among the description of the activities proposed there, to verify the occurrence of the different indicators. It was observed that environmental education practice is still restricted mainly to the areas of Science and Geography, which contrasts with the main indication, parameters and guidelines established, that this should be a practice that transcends the curriculum, pointing to a possible interdisciplinarity. We made suggestions for insertion of the environmental theme in different situations of its absence in the materials analyzed, trying to show concretely possibilities of approaching the environmental issue in all disciplines.
A situação ambiental atual configura um cenário preocupante, tornando inevitável a tomada de diferentes medidas que resultem em soluções superadoras dos desafios socioambientais, apontando para um mundo de sociedades sustentáveis. Como parte importante do complexo e articulado conjunto de medidas necessárias, a educação apresenta-se como essencial, uma vez que é capaz de possibilitar uma tomada de consciência que mobilize as pessoas para a transformação social. A educação ambiental é uma prática que incorpora temáticas hoje cruciais no desenvolvimento da sociedade em geral e, se implementada numa perspectiva crítica, reflexiva, transformadora e emancipatória, pode ampliar a potência de ação das pessoas nessa direção, favorecendo a desafiadora inflexão ora em demanda. No Brasil, esta prática está referida em conceitos e princípios conhecidos e instituídos, os quais devem ser seguidos no seu exercício, seja em projetos e programas de interação comunitária, seja em currículos trabalhados no ambiente escolar. Nesse contexto, a partir de uma avaliação dos Parâmetros Curriculares Nacionais do Tema Transversal Meio Ambiente e das Diretrizes Curriculares Nacionais em Educação Ambiental, este trabalho definiu quatro indicadores para análise do currículo oficial do ensino fundamental do Estado de São Paulo a respeito da abordagem da questão ambiental: conhecimento, participação, valores, contextualização. Pesquisa bibliográfica seguida de análise documental foram os procedimentos empregados na pesquisa, complementados ainda por levantamento de pesquisas empíricas com vistas a verificar a ocorrência de iniciativas educativas ambientais no currículo oculto, na prática escolar. A partir da análise documental do primeiro volume do Caderno do professor de todas as disciplinas do 6º ano/5ª série, buscou-se, em meio à descrição das atividades ali propostas, verificar a ocorrência dos diferentes indicadores. Observou-se que a prática educativa ambiental ainda está restrita, principalmente, às áreas de ciências e de geografia, o que se contrapõe à principal indicação, dos parâmetros e das diretrizes instituídos/as, de que esta deva ser uma prática transversal ao currículo, apontando para uma possível interdisciplinaridade. Foram feitas, então, sugestões de inserção da temática ambiental em diferentes situações de sua ausência nos materiais analisados, procurando mostrar concretamente algumas possibilidades de abordagem da questão ambiental em todas as disciplinas.

Full textAbstract:
In this thesis, the effects of size and stress on permeability, deformability and strength of fractured rock masses are investigated. A comparison study was carried out to examine the effects of considering, or not considering, the correlation between distributions of fracture apertures and fracture trace lengths on the hydro-mechanical behavior of fractured rocks. The basic concepts used are the fundamental principles of the general theory of elasticity, Representative Elementary Volume (REV), the tensor of equivalent permeability, and the strength criteria of the fractured rocks. Due to the size and stress dependence of the hydro-mechanical properties of rock fractures, the overall effective (or equivalent) hydro-mechanical properties of the fractured rocks are also size and stress-dependent. However, such dependence cannot be readily investigated in laboratory using small samples, and so numerical modeling becomes a necessary tool for estimating their impacts. In this study, a closed-form relation is established for representing the correlation between a truncated lognormal distribution of fracture apertures and a truncated power law distribution of trace lengths, as obtained from field mapping. Furthermore, a new nonlinear algorithm is developed for predicting the relationship between normal stress and normal displacement of fractures, based on the Bandis model and the correlation between aperture and length. A large number of stochastic Discrete Fracture Network (DFN) models of varying sizes were extracted from some generated large-sized parent realizations based on a realistic fracture system description from a site investigation programme at Sellafield, UK, for calculating the REV of hydro-mechanical properties of fractured rocks. Rotated DFN models were also generated and used for evaluation of the distributions of directional permeabilities, such that tensors of equivalent permeability could be established based on stochastically established REVs. The stress-dependence of the permeability and the stress-displacement behaviour were then investigated using models of REV sizes. The Discrete Element Method (DEM) was used for numerical simulation of the fluid flow, deformability properties and mechanical strength behavior of fractured rocks. The results show significant scale-dependency of rock permeability, deformability and strength, and its variation when the correlation between aperture and trace length of fractures are concerned, with the overall permeability and deformability more controlled by dominating fractures with larger apertures and higher transmissivity and deformability, compared with fracture network models having uniform aperture. As the second moment of aperture distribution increases, a fractured rock mass shows more discrete behavior and an REV is established in smaller value of second moment with much larger model size, compared with the models with uniform fracture aperture. When the fracture aperture pattern is more scattered, the overall permeability, Young’s modulus and mechanical strength change significantly. The effect of stress on permeability and fluid flow patterns in fractured rock is significant and can lead to the existence or non-existence of a permeability tensor. Stress changes the fluid flow patterns and can cause significant channeling and the permeability tensor, and REV may be destroyed or re-established at different applied stress conditions. With an increase in the confining stress on the DEM models, the strength is increased. Compared with the Hoek-Brown criterion, the Mohr-Coulomb strength envelope provides a better fit to the results of numerical biaxial compression tests, with significant changes of the strength characteristic parameters occurring when the second moment of the aperture distribution is increased.QC 20100702

Full textAbstract:
This thesis presents a systematic numerical modeling framework to simulate the stress-deformation and coupled stress-deformation-flow processes by performing uniaxial and biaxial compressive tests on fractured rock models with considering the effects of different loading conditions, different loading directions (anisotropy), and coupled hydro-mechanical processes for evaluating strength and deformability behavior of fractured rocks. By using code UDEC of discrete element method (DEM), a series of numerical experiments were conducted on discrete fracture network models (DFN) at an established representative elementary volume (REV), based on realistic geometrical and mechanical data of fracture systems from field mapping at Sellafield, UK. The results were used to estimate the equivalent Young’s modulus and Poisson’s ratio and to fit the Mohr-Coulomb and Hoek-Brown failure criteria, represented by equivalent material properties defining these two criteria. The results demonstrate that strength and deformation parameters of fractured rocks are dependent on confining pressures, loading directions, water pressure, and mechanical and hydraulic boundary conditions. Fractured rocks behave nonlinearly, represented by their elasto-plastic behavior with a strain hardening trend. Fluid flow analysis in fractured rocks under hydro-mechanical loading conditions show an important impact of water pressure on the strength and deformability parameters of fractured rocks, due to the effective stress phenomenon, but the values of stress and strength reduction may or may not equal to the magnitude of water pressure, due to the influence of fracture system complexity. Stochastic analysis indicates that the strength and deformation properties of fractured rocks have ranges of values instead of fixed values, hence such analyses should be considered especially in cases where there is significant scatter in the rock and fracture parameters. These scientific achievements can improve our understanding of fractured rocks’ hydro-mechanical behavior and are useful for the design of large-scale in-situ experiments with large volumes of fractured rocks, considering coupled stress-deformation-flow processes in engineering practice.QC 20141111

Previous issue date: 2010-05-20This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of Volume of the Rectangular Parallelepiped, Area and Perimeter of the Rectangle adding a study of the Area of the Circle. The research was developed along with students from the 6th level of the Elementary School, in a public school in Natal/RN. The pedagogical intervention was made up of three moments: application of a diagnostic evaluation, instrument that enabled the creation of the teaching module by showing the level of the geometry knowledge of the students; introduction of a Teaching Module by Activities aiming to propose a reflexive didactic routing directed to the conceptual construction because we believed that such an approach would favor the consolidation of the learning process by becoming significant to the apprentice, and the accomplishment of a Final Evaluation through which we established a comparison of the results obtained before and after the teaching intervention. The data gathered were analyzed qualitatively by means of a study of understanding categories of mathematical concepts, in addition to using descriptive statistics under the quantitative aspect. Based on the theory of Richard Skemp, about categorization of mathematical knowledge, in the levels of Relational and Instrumental Understanding were achieved in contextual situations and varied proportions, thus enabling a contribution in the learning of the geometrical concepts studied along with the students who took part in the research. We believe that this work may contribute with reflections about the learning processes, a concern which remained during all the stages of the research, and also that the technical competence along with the knowledge about the constructivist theory will condition the implementation of a new dynamics to the teaching and learning processes. We hope that the present research work may add some contribution to the teaching practice in the context of the teaching of Mathematics for the intermediate levels of the Elementary School

Дисертація на здобуття наукового ступеня кандидата технічних наук (доктора філософії) за спеціальністю 05.11.17 «Біологічні та медичні прилади і системи». – Національний технічний університет «Харківський політехнічний інститут», Харків, 2019. Дисертація Махоніна М.В. присвячена вирішенню однієї з актуальних науково-технічних задач сучасного медичного приладобудування – підвищенню ефективності генератору медичного озону за рахунок визначення параметрів розрядної камери, напруги живлення та витрати кисню. На даний час у світі активно використовують озон та його суміші для широких потреб різних галузей. Для отримання озону використовуються спеціальні генератори озону різних типів у залежності від сфери їх застосування. Ці генератори відрізняються розмірами, кількістю озону, що генерується за відрозок часу та інші. Особливістю ж генераторів медичного озону є те, що необхідно підтримувати задані параметри отримуваної озоно-кисневої суміші на протязі усього часу проведення процедури, а у якості робочого газу використовується медичний кисень. Це дозволяє реалізовувати методики озонотерапії для максимально ефективного лікування пацієнтів. Типові параметри озоно-кисневої суміші, які повинен забезпечувати медичний генератор озону регламентуються в Україні «Методиками для застосування озону в медичній практиці», які були затверджені Міністерством охорони здоров’я в 2004 році. Згідно сучасної редакції цих методик концентрація озону в озоно-кисневій суміші повинна змінюватись у діапазоні від 0,1 до 80 мг/л, а витрата суміші від 0,1 до 1 л/хв. Медичні генератори озону активно використовуються у кабінетах озонотерапії та медичних установах України, країн СНД, а також країн Латинської Америки. Щорічно у світі проводиться велика кількість конференцій присвячених озонотерапії, на яких вона отримує свій подальший розвиток Практичне використання генераторів медичного озону свідчить, що більшість апаратури, що використовуються, потребує вдосконалення для забезпечення роботи на основі сучасних медичних рішень у лікуванні. Тобто розробка сучасного генератора потребує не тільки відповідність параметрів сучасним вимогам, а й ще запас на розвиток та можливість збільшення значень концентрації озону. Крім того, у більшості медичних генераторів озону спостерігається невідповідність заявлених параметрів озоно-кисневої суміші та значення продуктивності по озону. Продуктивність генератора озону, в свою чергу, залежить від: параметрів розрядної камери, параметрів напруги живлення, параметрів
робочого газу. Вирішенням проблему пошуку оптимальних значень цих параметрів для підвищення ефективності роботи генератора озона займаються багато науковців, серед яких можна виділити японських, німецьких та науковців з країн СНД. Але на даний момент ще не існує універсальної моделі розрахунку параметрів генератору Таким чином, задача підвищення ефективності роботи генератора медичного озону за рахунок визначення найкращих параметрів його вузлів, що дозволить підвищити якість процедур озонотерапії є актуальним і перспективним напрямком розвитку генераторів озону. У дисертаційній роботі вперше побудовано математичну модель синтезу озону в розрядній камері генератора медичного озону, яка враховує вплив не тільки параметрів електричної енергії, а також параметрів розрядної камери та робочого газу. Отримані залежності впливу параметрів електричної енергії на синтез озону у розрядній камері на основі проведеного аналізу та з використанням комп’ютерного моделювання. Отримала подальший розвиток модель процесу генерації озону в бар'єрному розряді, яка, на відміну від існуючої, враховує не тільки параметри напруги живлення і розміри камери, але і процеси, що відбуваються в розрядному проміжку. Запропоновано методику розрахунку основних параметрів генератора озону при його розробці, що дозволяє підвищити ефективність синтезу озону. Практичне значення одержаних результатів полягає у обґрунтованні переліку параметрів, що чинять найбільший вплив на продуктивність генератора медичного озону; інженерних розрахунках параметрів генератора медичного озону, які дозволили оптимізувати конструкцію генератора з заданими параметрами; реалізації експериментального зразка генератора медичного озону з вдосконаленою системою автоматичного регулювання витрати газу, що дозволила забезпечити виконання широко спектру процедур озонотерапії. Отриманні практичні результати дисертаційної роботи впроваджені на НВП «Еконіка» при розробці та виготовлення сучасних генераторів медичного озону, а також розроблений макетний зразок пройшов медичну апробації у медичному центрі «Пульс-медика» та у Інституті медичної радіології ім. С.П. Григор’єва.Thesis for the degree of candidate of technical sciences (PhD) in the specialty 05.11.17 “Biological and medical devices and systems”. -National Technical University "Kharkov Polytechnic Institute", Kharkov, 2019. The thesis is devoted to the solution of one of the current scientific and technical problems of modern medical instrument making - increasing the efficiency of the medical ozone generator by determining the parameters of the discharge chamber, the supply voltage and the oxygen consumption. Currently, ozone and its mixtures are widely used in the world for the wide range of applications. Different types of ozone generators depending on their application are used for ozone synthesis. These generators differ in size, the amount of ozone generated by the time span, etc. The peculiarity of the generators of medical ozone is that it is necessary to maintain the prescribed parameters of the resulting ozone-oxygen mixture throughout the entire duration of the procedure, and medical oxygen is used as the working gas. This allows us to implement ozone therapy techniques for the most effective treatment of patients. Typical parameters of the ozone-oxygen mixture, which the ozone generating plant should provide, are regulated in Ukraine "Methods for the application of ozone in medical practice", which were approved by the Ministry of Health in 2004. According to the modern version of these methods, the concentration of ozone in the ozone-oxygen mixture should vary in the range from 0.1 to 80 mg / l, and the flow rate of the mixture is from 0.1 to 1 l / min. Medical ozone generators are actively used in the offices of ozonotherapy and medical institutions in Ukraine, CIS countries, as well as Latin American countries. A large number of conferences devoted to ozone therapy are being held annually in the world in which it is further developed. The practical use of generators of medical ozone shows that most of the equipment used needs to be improved to provide work on the basis of modern medical solutions in treatment. That is, the development of a modern generator requires not only compliance with the parameters of modern requirements, but also a stock for development and the possibility of increasing the values of ozone concentration. In addition, in most medical ozone generators there is a discrepancy between the stated parameters of the ozone oxygen mixture and the value of ozone productivity. The performance of the ozone generator, in turn, depends on: the parameters of the discharge chamber, the parameters of the supply voltage, the parameters of the working gas. Many scientists, including Japanese, German and scholars from the CIS countries, are engaged in solving the problem of finding the optimal values of these parameters for increasing the efficiency of ozone generator operation. But at the moment there is still no universal model for calculating the parameters of the ozone generator. Thus, the task of increasing the efficiency of the medical ozone generator by determining the best parameters of its nodes, which will improve the quality of ozone therapy procedures, is an urgent and promising direction for the development of ozone generators. In the dissertation, for the first time, a mathematical model of the synthesis of ozone in a digital chamber of the medical ozone generator was constructed, which takes into account the influence not only of the parameters of electric energy, but also of the parameters of the discharge chamber and the working gas. The dependence of the influence of electric energy parameters on the synthesis of ozone in a discharge chamber was obtained on the basis of the conducted analysis and using computer simulation. The model of the ozone generation process in the barrier discharge has been further developed, which, in contrast to the existing one, takes into account not only the power supply parameters and camera dimensions, but also the processes occurring in the discharge gap. The method of calculation of the basic parameters of the ozone generator during its development, which allows increasing the efficiency of ozone synthesis, is proposed. The practical value of the results obtained is to justify the list of parameters that have the greatest impact on the performance of the medical ozone generator; engineering calculations of parameters of the generator of medical ozone, which allowed to optimize the design of the generator with the given parameters; the implementation of an experimental model of the medical ozone generator with an improved system of automatic regulation of gas consumption, which allowed to ensure the implementation of a wide range of procedures for ozone therapy. The practical results of the dissertation work were introduced at the Scientific-Production Enterprise "Econika" in the development and manufacture of modern generators of medical ozone, and also a prototype sample was developed, was tested at the medical center "Pulse Medika" and at the Institute of Medical Radiology N.A. Grigoriev.

The purposes of this study were to develop an augmented reality (AR) system to assist elementary school students learning volume concepts in Geometry. Our developed AR system provided additional information on a real composite object, which would then help students calculate the volume of the object. We adopted the Quasi-experiment Research method to evaluate the effectiveness of the system in terms of students’ learning achievement, attitudes toward learning and perceptions on using the system. The participants were 53 fifth-grade students, with 25 students in experimental group using the AR system and 28 students in control group using traditional method. The results revealed that the AR system improved students’ achievement scores and students in the AR group showed more confidence than the control group in learning stratified strategy and were satisfied with the experience of using AR system. We suggest future studies to improve the user interface and functionality of our developed system and to develop similar systems to help students learn a broader range of the volume concepts.

This study presents the representative elementary volume (REV) of P32 (fracture intensity) and hydraulic conductivity of fractured rock mass. Discrete fracture network (DFN) generated by FracMan is adopted to create rock mass models. A series of parametric studies including dip angle, dip direction, Fisher constant κ, size of rock mass model, shape of rock mass model, specimen volume, fracture diameter, and P32 were investigated to study the REV of P32. Based on the results of the parametric studies, a novel equation to quantify the COV (Coefficient of variance) of P32 in terms of specimen volume, fracture diameter and P32 was established. A precise REV size can be obtained easily by assigning the acceptable COV. Thereafter, some case studies were used to verify the proposed novel equation. Conventional Oda and Oda gold were adopted to estimate the hydraulic conductivity of the fractured rock mass. By using Oda conventional, a series of parametric studies including specimen volume, fracture diameter, P32, transmissivity, and aperture were investigated to study the REV of hydraulic conductivity. Subsequently, that REV of hydraulic conductivity was compared with the REV of P32. In the other hand, by using Oda gold, only P32 was chosen as parametric study. Eventually, a proposed new method was conducted by examining the Monte Carlo simulation for REV of hydraulic conductivity determination.

The purpose of this study is to compare the differences between Nan-I- Edition elementary school mathematics textbook in Taiwan and Everyday Mathematics Edition elementary school mathematics textbook in USA in term of the volume materials. This study applies the method of content analysis and the tool of concept mapping. It focuses on when the concepts appear, how the concepts are arrangesd and how the contents are present. The study indicates that both two editions are present the materials of capacity at the second grade. However, the materials of volume are one year earlier in EM- Edition, but are wider and deeper than those in Nan-I- Edition. Nan-I- Edition explains the materials of volume at the first time explicitly, but less focuses the estimation of measurement. There are more materials of criterion unit and unit conversion in EM-Edition. Nevertheless, Nan-I-Edition puts more focus on unit operations. These two editions introduce and present the formulas of volume using different ways. The contents in EM- Edition have more integrated problems which connect with real life, and need to apply more mathematical concepts to strategies of problems solving.

The purpose of the research was to explore the Elementary Social Studies textbooks complied in accordance with curriculum standards of 1993, including Nani, knsh, national offical, Senseio and Hanlin textbooks from the perspective of Multiple Intelligences theory (MI theory) to see whether the mentioned textbooks used multiple instruction channels. The researcher employed both content analysis and interview method to do this study. The exploration in the thesis included three focal points: 1. Understanding the distributed proportion of MI theory appeared in textbooks; 2. Comparing the similarity and the difference of MI theory appeared in textbooks; 3. Exploring the total distribution situation of MI theory appeared in textbooks, and understanding the factors of those results. Studied from above, the main results were synthesized as follows. 1.The distribution proportion of MI theory appeared in five different textbooks. (a)Low proportion of Multiple Intelligences in five different textbooks’ “Understanding Taiwan Materials.” The six units of “Understanding Taiwan Materials” among the five versions rarely employed MI instruction channels, except the units of “Folk and Art,(Nani, volum7, unit3), “Folk and Art”(Knsh, volum8, unit1), “Art and Life”(national official, volum8, unit3), “Natural Resources”(Senseio, volum7, unit2), “Folk and Art”(Hanlin, volum7,.unit3) and “Natural Resources”(Hanlin, volum7,.unit2). Within the five diverse textbooks, only six units out of the total thirty units placed more emphasis on the learning approach of Multiple Intelligences. Therefore, the proportion of MI theory is about one—fifth. (b) Nil proportion of Multiple Intelligences in the units of “Understanding Taiwan Materials” commonly seen in five versions of textbooks. 2. The compared results of Multiple Intelligences theory appeared in different textbooks. (a)As a whole, the total distribution situation of MI theory in Elementary Social Studies Textbooks’ “Understanding Taiwan Materials”, the more popular intelligences were linguistic intelligence, logical-mathematical intelligence and spacial intelligence. In the organization of “Understanding Taiwan Materials”, the more popular intelligent items were linguistic intelligence, logical-mathematical intelligence and spacial intelligence; the more rarely intelligent items were musical intelligence, bodily-kinestetic intelligence, and naturalist intelligence. (b)Among the five different textbooks’ “Understanding Taiwan Materials”, the more popular intelligences were linguistic intelligence, logical-mathematical intelligence and spacial intelligence. Finally, based on the research results above and the deficiency of the research, suggestions were offered for further study and textbook organizing.

Volume is an important mathematical concept for elementary school students. Everyone can see, touch, and use three-dimensional objects in the life. But there is a problem for teachers that some students cannot really comprehend the Volume concept's meaning because their spatial abilities are poor. When they learn the Volume concept in the Math class, they will have the misconception about Volume. Therefore, the purpose of this study was to investigate the school children's learning motivation and achievement by constructing a game-based mathematical learning system with the Volume concept. Forty fifth-grade elementary school students took part in this experiment. All participants were randomly divided into two groups with the same Math level. The experimental group learns Volume concept with the game-based learning system, and the control group learn the same materials with a digital multimedia learning system. All participants were evaluated on their learning motivation and achievement by the pre-test and post-test. The results indicated that there were significant differences between the scores of pre-test and post-test in learning achievement for the experimental group (p = .002), but for the control group were not (p = .099). It also showed that the game-based learning system can really increase students' learning achievements. For learning motivation, there were significant differences between the scores of pre-test and post-test in learning motivation for the experimental group (p = .004), but not for the control group (p = .425). It showed that the game-based mathematical learning system can really increase school children's learning motivation, draw their attention, and help them learn better.

In recent years, the large-scale construction projects and environmental resources related issues had brought attentions and rapid development on hydrogeology and other academic field connected to it. Rock engineering, including large-scale underground laboratory, tunnel excavation and hydrogeological well site, requires a certain degree of understanding on hydrogeology and hydraulic parameters, in order to facilitate subsequent planning and related construction. However, the presence of discontinuities in rock mass generates heterogeneity and anisotropy in its engineering characteristics, increasing variation of hydraulic and conductivity parameters, resulting in difficulty for determining representative parameters. Investigation and characterization of hydrogeological parameters of fracture rock masses are crucial to underground water exploiting. Among which, defining the hydrogeological representative elementary volume of the site is one of the key items. How to evaluate the hydrogeological unit to the scale of the target rock engineering is an important issue in hydrogeological parameters characterization. Based on previous research results, this thesis present an assessment process for representative elementary volume on hydraulic parameter characterization on account of a hydraulic parameter characterization model for fractured rock mass. Investigation and statistical test are applied to estimate the variation degrees of representative elementary volume in site and associated hydraulic conductivity in rock mass, which further determine the scale influence on each hydraulic characteristic parameters, the methodology of the establishment and extension of application is through by Heshe hydrogeological well site, and another tunnel case project in initiative in north Taiwan. The evaluation method of representative elementary volume in hydraulic characteristic establish by statistical error propagation theory to calculate the varying degrees between the characteristic parameters and hydraulic conductivity, and the empirical formula of different hydraulic conductivity is discussed to find the variation range and plotted out different scales in a result. In order to understand the behavior of hydraulic conductivity associated with representative elementary volume changes, this research applies groundwater modeling system to establish numerical model and analysis it. Firstly, the anisotropy is simulated with a single element, the error between the two elements is calculated by numerical solution and analytic solution. Then, convert the goal of simulation scale to in-situ cross-hole pumping test which in heshe well site. Secondly, parameter sensitivity analysis is carried out to understand the representative elementary volume and its related parameters. Scale variation is using for complete numerical simulation methodology parallel verification, and establish the accuracy and correctness of the model. The case study is aimed at extending the application of different representative elementary volumes on the volume of seepage flow caused by tunnel excavation, which extend the application of methodologies in a large number of site surveys and numerical models. The results show that the representative elementary volume evaluation program can effectively describe the change of the hydraulic characteristic parameters and the hydraulic conductivity coefficient with the scale variation by the statistical error propagation accumulation theory, and verify the groundwater anisotropy by numerical simulation. The related parameter sensitivity analysis shows that the numerical solution and the analytical solution will produce a certain range of errors in the setting of the boundary condition. The determination of the error value can provide the numerical model to improve the accuracy and correctness of the subsequent research. The hydraulic characteristic parameters of representative elementary volumes are on different scales, which changed in the groundwater seepage caused by tunneling, that with a certain degree of influence of groundwater through the three-dimensional simulation. We provide a valuable technical reference from the conceptual model, narrative model, and hydraulics model all the way to numerical model, through the outcome of methodology in designing verification and applying in this study.

This study is about application of the unit: volume of sixth-grade math of elementary school. In this study, the development of polychotomous scoring based on Professor Takahiro’s SP table analysis theory is used and applied to this research on teaching assessment. The participants’ degrees of response are used to understand their learning situations in volume and to provide teachers with references on teaching this unit and remedial teaching. The participants are thirty four sixth-graders of the elementary school in Taichung city. Caution Index for Students, CS calculated from the SP table analysis software, Caution index for problems, CP, and the coefficient of variation are adopted to conduct the diagnostic analysis of test items and the analysis of students’ learning. In Professor Takahiro’s SP table analysis theory, the dichotomous scoring (right- 1 point, wrong- 0 point) is used. However, polychotomous scoring is used in this research to calculate CX and CP. There are totally thirty- two items, item one to item twenty-four: 3 points, and item twenty-five to item thirty-two: 3.5 points. The results of the values of CS are as follow. From 0 to 0.5, there are twenty-one students, indicating that their learning is normal without serious unusual situation. From 0.5 to 0.75, there are thirteen students, which means teachers should pay attention to their serious unusual situation. The CS value >0.75 indicates the very serious usual situation and there is zero student in this range. The CP coefficient value >0.75 are Item3, Item8, Item9, Item11, Item12, Item19, Item22, Item24, and Item29. Item3 and Item19 are easier question for the students due to the > 90 % of the correct answering rate. This result implies that teachers have to pay attention to the inappropriate items when they are designing the test items. The results show the extraordinary function of evaluating the test items of polychotomous scoring of S-P table analysis theory. It can be used not only to analyze the content of the test of the minorities but also to classify the participants, which is the lack of the item response theory. Moreover, these findings could provide the teachers who would like to teach and evaluate with references for remedial teaching.

This research also discussed the influence of gender in the experimental groups. Problems faced by the teachers during the integration of Interactive Whiteboard into teaching activities and the associated resolutions are also documented. The conclusion of this research is as following： 1. The experiment data shows that there exhibits significant difference on the learning performance between the students who received instructions with integrated Interactive Whiteboard and those who received traditional classroom instructions. 2. The learning attitude as reflected in the performance of “ Motivation for inquiry mathematics ＂is significantly different between the students who received instructions with integrated Interactive Whiteboard and those who received classroom instructions. 3. The result shows that the introductory activity of the Interactive Whiteboard before the class, the learning performance in the “volume” chapter in mathematics for both boy and girl students did not have a significant difference. 4. Most students who received the instructions with integrated Interactive Whiteboard have positive feedback toward the teacher. Students prefer the instructions with integrated Interactive Whiteboard for learning mathematics, and wish that such method can be bring to other subjects. 5. Problems faced by the teachers and the associated resolutions： (1)The teacher cannot prepare for the instructions with integrated Interactive Whiteboard alone. The teacher needs the administration support. (2)Owing to the limitation of multimedia classroom, the teaching activity lacks mobility. Therefore the teacher could provide more opportunities for students to operate the Interactive Whiteboard to promote the motivation.

The study is based on Rule Space Model cognitive diagnostic methods, which was proposed by Tasuoka(1983). The subjects of this study were the fourth-grade students from two classes of an elementary school in New Taipei County. Through the analysis of the examinees’ cognitive response patterns, it is effective to figure out the volume learning results on those fourth-grade students, and to explore the mastery level of their potential knowledge attributes. The Students in the experimental group could correspond to 3 kinds of attribute combinations from the target unit of this study. According to the mastery level of students’ potential knowledge attributes, 9 kinds of knowledge states could be classified and four learning paths could be identified. According to the post-test analysis of the students' learning achievement in the experimental group, from the percentage of people in each knowledge state, the possible learning path for students is derived as path four. The results showed that after the experimental group of students accepted the individual diagnostic suggestions, there was a significant improvement in post-test performance. By analyzing students’ knowledge status, they not only help students understand their own learning weaknesses, but also build their self-learning ability. It can also helping teachers adjust follow-up teaching strategies and improving teaching effectiveness.
