Peer assessment in educational setting, refers to activities in which students provide grades or comments on other students' accomplishments such as writing, presentation, or performances. In case of writing, peer assessment can allow instructors to give out more writing assignments, which were often avoided because of the burden of grading. Moreover, grading other students' writing can enhance learning by having students participate in the assessment process. This review will introduce major peer assessment systems and results from empirical studies on peer assessment, examine obstacles to its more wide-spread use, and discuss topics for further research. We hope this paper will facilitate further studies and use of peer assessment in actual educational settings, and eventually lead to many changes in assessment and teaching in Korea.

It is noted that although the current state of development of web-based English education (hereafter referred to as WBEE) might not meet the criteria some educators have set for themselves in the field, students certainly seem to prefer studying in a web-based and computer-assisted learning environment. This kind of demand is fueling the drive to develop more suitable variations of WBEE. In order for WBEE to work out, a teacher should be a multifunctional type of instructor handling responsibilities such as the role of scriptwriter to create text, act as technician for the sound mixing and recording, preside over online chat rooms and discussion boards, and finally, as webmaster to maintain the site and supervise all academic/ clerical work related to the course. Therefore, it is suggested that WBEE be accompanied by a small personnel to divide the labor and lessen the burden on the actual teacher. Finally, it is noted that the traditional relationship between students and teacher may no longer be sustainable since WBEE does not provide the face-to-face style of class discussion and office hours in its current form. Until the technology is fully developed to compensate for these kinds of differences, it is an immediate challenge to provide other more compelling reasons for students to participate in WBEE.

This study explored the socialization of novice Home Economics(HE) teachers employing a qualitative research method. Data was collected through in-depth interviews with four novice HE teachers from secondary schools. The collected data was analyzed inductively by NVivo, a kind of CAQDAS. The following analysis was organized around three stages of teachers' careers: first, as for influences on teacher socialization prior to formal teacher education, their experiences on 'apprenticeship of observation' provided them both positive and negative role models; second, as for the socialization role of pre-service teacher education, they mentioned that college courses were poorly connected to classroom realities with only a few helpful lectures on HE Education; third, as for socialization in the workplace and its culture, the novice HE teachers were confronted with many kinds of problems including isolation in the classroom, in-service training programs not geared to novices, an overwhelming workload, and so on. Because of these problems, they yearned for and also formed networks with other HE teachers in order to overcome their limitations. The findings supported the notion that interactive and dialectical processes exist during all stages of HE teachers' careers. This study suggests that the teacher in-service training programs are more relevant, and that the introduction of mentoring programs and classroom manuals and teacher manuals would be helpful in practice. These innovations call for cooperation between universities and provincial offices of education for teachers' professional success in teacher socialization.

In this paper, we propose a hierarchical hybrid neural network for detecting faults of induction motor. Implementing the classifier based on the input and output data, we apply appropriate transform and classification method at each step. In the proposed method, after obtaining the current of state of motor for each period, we transform it by Principle Component Analysis(PCA) to reduce its dimension. Before the training process, we use the conditional Fuzzy C-means(FCM) for obtaining the initial parameters of neural network for more effective learning procedure. From the various simulations, we find that the proposed method shows better performance to detect and diagnosis of induction motor and compare than other methods.

In this paper, we propose a new approach to learning a discriminative model for figure/ground segmentation by incorporating the bag-of-features and conditional random field (CRF) techniques. We advocate the use of image patches instead of superpixels as the basic processing unit. The latter has a homogeneous appearance and adheres to object boundaries, while an image patch often contains more discriminative information (e.g., local image structure) to distinguish its categories. We use pixel-level sparse coding to represent an image patch. With the proposed feature representation, the unary classifier achieves a considerable binary segmentation performance. Further, we integrate unary and pairwise potentials into the CRF model to refine the segmentation results. The pairwise potentials include color and texture potentials with neighborhood interactions, and an edge potential. High segmentation accuracy is demonstrated on three benchmark datasets: the Weizmann horse dataset, the VOC2006 cow dataset, and the MSRC multiclass dataset. Extensive experiments show that the proposed approach performs favorably against the state-of-the-art approaches.

As IT technology improves, software is being more and more important. Industry demands higher level of programming ability from university graduates. As a result, programming related courses already take higher possession of electronics department curricula. But even though the environment likewise computer laboratory is improved as much, and professors have tried to enhance the quality of their lectures and educational results, still programming education does not match the demand of our society and industry. In this paper, we introduce the overview of programming education in electronics department, KUT and discuss problems in programming language education especially for the 1st year students, since programming education to the 1st year university students becomes one of the most important part as it deals with fundamentals on programming language and we suggest its improvement directions in regards with students, teaching materials, professors, class size, and class hours.

The United States curriculum reform movement has recently started in each area of science education. The initiatives on curriculum reform stem from a notion that the low rate of science curricula offered in schools has been a serious problem. The schools in the United States are not only facing a lack of offerings within science curricula but also low enrollment in science courses, especially in physics, chemistry, and earth science. This trend resulted in low performances on international achievement tests including TIMSS and PISA. This paper introduces the efforts to solve existing problems through curriculum reform; including ChemCom, BioCom, EarthComm, and Active Physics. In this paper, a discussion is presented to show how the curricula can help address the status quo in science education. More specifically, this paper focuses on curriculum reform in high school earth science (EarthComm), providing a closer look at the scope and sequence of the reform movement. EarthComm was chosen because it was released based on the development of the National Science Education Standards (NRC, 1996). Consequently, EarthComm became a curriculum that espoused the visions of the Standards, which has been guiding the reform of the US curriculum. At the end of this paper, two research outcomes of the EarthComm curriculum implementation in schools are discussed in terms of student learning and differences from conventional curricula.

Since the England's Parliament revised the British copyright law and enacted the first copyright exception specifically for libraries (user or service) in 1956, copyright exceptions applicable to libraries have been an important part of world copyright laws through the last few decades. Copyright exceptions for libraries are a critical legal tool to preserve intellectual and cultural heritage, promote equitable access to knowledge and information to the public, and to support learning and research. Based on these reasons, this study analyzed and compared the current state of copyright structure and limitations or exceptions for library in six major countries(United States, United Kingdom, Germany, France, Japan, and Republic of Korea).

The visibility deteriorates in hazy weather and it is difficult to accurately recognize information captured by the camera. Research is being actively conducted to remove haze so that camera-based applications such as object localization/detection and lane recognition can operate normally even in hazy weather. In this paper, we propose a nonlinear model for depth map estimation through an extensive analysis that the difference between brightness and saturation in hazy image increases non-linearly with the depth of the image. The quantitative evaluation(MSE, SSIM, TMQI) shows that the proposed haze removal method based on the nonlinear model is superior to other state-of-the-art methods.

A criterion for evaluation of burners has changed recently, and the environmental problems are raised as a global issue. Burners with higher thermal efficiency and lower oxygen in the exhaust gas, evaluated better. To comply with environmental regulations, burners must satisfy the $NO_x$ and CO regulation. Consequently. 'good burner' means one whose thermal efficiency is high under the constraint of $NO_x$ and CO consistency. To make existing burner satisfy recent criterion, it is highly recommended to develop a feedback control scheme whose output is the consistency of $NO_x$ and CO. This paper describes the development of a real time flame diagnosis technique that evaluate and diagnose the combustion states, such as consistency of components in exhaust gas, stability of flame in the quantitative sense. In this paper, it was proposed on the flame diagnosis technique of burner using Neuro- Fuzzy algorithm. This study focuses on the relation of the color of the flame and the state of combustion. Neuro- Fuzzy learning algorithm is used in obtaining the fuzzy membership function and rules. Using the constructed inference algorithm, the amount of $NO_x$ and CO of the combustion gas was successfully inferred.
