This research aimed to explore the effects of collaborative writing activities in a mathematical context, specifically pertaining to areas such as numbers and operation, geometrical figure, and measurement in Mathematics: Level 5-b, on their mathematical achievement gain and disposition among Grade 5 students. To do this, out of a total of 62 students selected from two Grade 5 classes of J Elementary School in Dalseo-gu, Daegu City, who were found to be homogenic from the tests of math performance and dispositions, an experimental group(n=31) was designed and compared to a control group (n=31). Over a six week period from October to November in 2009, the experimental group was given collaborative writing lessons in math classes while the control group was given teacher-oriented regular lessons. The results were as follows. First, there was more or less considerable, though not significant, difference in overall mathematical achievement in the students experiencing collaborative writing activities when compared with the students in the control group. However, in terms of numbers and operation, a sub-category of mathematics, there was significant difference between the two groups. Second, the students experiencing collaborative writing activities were more positively affected in all sub-categories of mathematical disposition: confidence, flexibility, determination, curiosity, reflection, and value, than those in the control group. In summing up, the exposure of collaborative writing activities to mathematics learning was found to help students not only to have a concrete and proper grasp of the relevant problem solving process, which was observed from their mathematical achievement gain especially in the sphere of numbers and operation, but also to have their mathematical disposition set towards more positive direction, which was seen in all sub-categories of mathematical disposition measurement.

The purpose of this study is to investigate the perception of pre-service secondary English teachers on peer feedback in English composition. For this purpose, a total of 37 students who took the English composition class for 15 weeks participated in the survey. After completing the survey, data were analyzed to find out the students' perception on peer feedback performed in their English composition class through frequency analysis and descriptive statistics. The findings of this study are as follows: First, the students showed positive attitudes towards on peer feedback activities. Second, the participants had received considerable help in the content, ideas and organization of their composition. Third, noticing that they all have made similar mistakes in their writing, the subjects were relieved to know that they are not falling behind their other colleagues. Fourth, the subjects did not trust the feedback contents among the peers, which were found in both the feedback giver and receiver. In particular, feedback from peers who had low English proficiency was rarely helpful. Fifth, the students were afraid that their relationship might become uncomfortable with peers when they pointed out peer's writing errors or made specific suggestions about their peer's writing. Finally, pedagogical implications were discussed based on the research findings.

Grammar has long been regarded as an important element in foreign language learning and has received a lot of attention from foreign language learners and researchers. However, in the process of learning, learners will confront an increasing number of words some of which may have multiple meanings. It is not easy for language learners to memorize and master the correct use of these words, especially in terms of pragmatics. Some learners may use the grammar correctly, but their writing or utterance may feel unnatural in discourse. In Korean, '나다, 들다' are two basic verbs, but they have many different meanings which cause a lot of confusion among learners of Korean as a foreign language. In this article, the writer attempts to make a distinction between the collocations of the two verbs '나다, 들다' and provides an effective method for teaching the learners of Korean in China.

This paper introduces a general purpose Associative Processor(AP) which is very efficient for search-oriented applications. The proposed architecture consists of three main functional blocks: Content-Addressable Memory(CAM) arry, row logic, and control section. The proposed AP is a Single-Instruction, Multiple-Data(SIMD) device based on a CAM core and an array of high speed processors. As an application for the proposed hardware, we present a parallel algorithm to solve a global routing problem in the layout process utilizing the processing capabilities of a rudimentary logic and the selective matching and writing capability of CAMs, along with basic algorithms such a minimum(maximum) search, less(greater) than search and parallel arithmetic. We have focused on the simultaneous minimization of the desity of the channels and the wire length by sedking a less crowded channel with shorter wire distance. We present an efficient mapping technique of the problem into the CAM structure. Experimental results on difficult examples, on randomly generated data, and on benchmark problems from MCNC are included.

Business process in e-government mostly embody as the flow of documents. Constructing a web-based document flow system becomes an critical task for today s digital government. But few of them use an off-the-shelf workflow product. Why? One of the reasons is that most of the workflow system are heavyweight, monolithic, and package a comprehensive set of features in an all-or-nothing manner. Another reason is that workflow technology lacks the constructs and modeling capability as programming language. It is incumbent on government IT organizations to transform their solution development to component-based computing model. Component technology isolates the computation and communication parts, but how to compose different software components is still a hard nut. An integrated development environment is necessary for CBSD. In this paper we propose a XML and component-based document flow-oriented integrated development environment (DFoIDE) for software developers. By writing some xml configure file, and operate on DFoIDE, developer can construct a workflow application quickly. This method divides system to several components and the activities in process are implemented as business component. Different components are discribed detailedly in this paper, especially one of the core component. Component Integrating Tool. Different perspectives in workflow application are seperated and depicted as different XML files. Correspondly, A component composition method for developing workflow application instead of workflow itself is proposed.

Holographic Data Storage System, one of the next generation data storage devices, is a 2-dimensional page oriented memory system using volume holograms in writing and retrieving process. Recently photopolymer with disc type substrate was selected as a media for the Holographic Data Storage System. The disc tilt occurs when the media rotates and the external disturbance applies. The disc tilt causes the change of the angle between the reference beam and the media, the data cannot be retrieved with the right angle or other data page is retrieved. The tilt is generated in a 2-axis direction (tangential, radial). The tangential tilt direction is the same with the multiplexing plane, while the radial tilt direction is a perpendicular to the multiplexing plane. In this research we propose 2-axis tilt angle servo system. The tilt errors are measured by using external photo detector and the additional red laser. Then the tangential direction tilt is compensated by using the galvano mirror. Also the radial direction tilt is compensated by the rotating prism between the relay lens in the reference field. Finally we confirm the compensation results through the Signal to Noise Ratio(SNR) and Bit Error Rate(BER).

Dance is an art that includes not only art historical facts, but also a series of processes for dancers' body, choreography, and the creation of entire process of dances and their lives. In other words, dance is the art of embodying the experience and consciousness of the dancer as the subject, and embodying it through the physical body, and therefore, the existing empirical study which relies solely on the literature in the history of dance study is difficult to deliver a complete history. Oral history is a new methodology historical writing that overcomes the limitations of research methods based on literature centered documents. Oral history in the field of dance is that the dancer becomes the subject of the history of dance's narrative. The memory and testimony of a dancer can become a history, complement the missing parts of the documentary record, and amount to analysis and interpretation to attempt the history of dance from various perspectives. The history of dance through oral history analysis thus generates another view from the literature. The oral history is acted as a prism that can explore the sociocultural discourse of the time and the history of dance. As a new academic challenge for the history of dance field, I expect to be able to review the artistic, social, and cultural functions and roles of dance beyond the limit of existing literature-oriented history study and to be able to progress to various the history of dance.

The purpose of this study is to listen to vivid story on economic life of marriage immigrant women using phenomenological study out of qualitative study methods, and to analyze the meaning of dynamicity of experiences through in-depth interviews. The research question is "What is the meaning of economic life that marriage immigrant women experience?" From the research, 67 meaningful statements were abstracted and 15 core meanings were organized. The 15 core meanings were categorized as 5 theme categories such as 'Tough Life', 'Unstable Income such as Children Education Expense and Insurance Premium', 'Search for Changes in Life Style for Adaptation', 'Pursuit of Economic Stability through Employment', 'Expectation of Supports and Return to Married Woman's Parents' Home.' The researcher made structural description through first person speaker for the application of hermeneutical writing. In other words, the meaning of economic life of marriage immigrant women in Korea is 'difficult coping process to family-oriented culture pursuing changes in life style to adapt themselves to difficult reality.' Various undertones of practice were proposed through those statements such as policy to expand opportunities to receive an old-age pension by applying 'Joint Scheme for Couples' (Virtual Name) to People's pension for stable economic life of marriage immigrant women in old age.

After developing literacy education programs using coaching techniques, applying them to literacy learners, in order to see how they have an impact on improving learning achievement, we selected 13 senior literacy learners in U city and chose qualitative research method based on in-depth interviews, observation journals, and learning materials. Literature education programs using coaching techniques are a process-oriented model consisting of four stages of mind-opening, introducing positivity, strengthening learning competence and assistance, confidence and persistence. You can find the results as following. Firstly, communication between teachers and learners was expanded in the first stage, and secondly, self-directed learning ability was strengthened in the second stage by forming a positive mind. Thirdly, the results of utilizing the three-stage balanced literacy teaching method and interaction teaching method resulted in confidence in reading and writing, leading to an increase in self-efficacy. Fourthly, the fourth stage showed the results of improving learning achievement, which overcame the fear of learning with active praise and continuous encouragement and implied hope for higher courses. As a result of the above-mentioned research, I think literacy education programs using coaching techniques can be useful as an educational method for learners in the field of literacy education.
