Pupils with learning impediments in elementary schools have difficulties in learning numerical calculations. Numerical concepts, the basis of numerical calculations, require repetitious exercises, and it has been widely reported that computer-mediated learning motivates the learners to concentrate on their learning for longer hours. The aim of the research is to develop and apply a Web-based courseware to experimental groups to improve learning numerical concepts of the learners with learning difficulties in elementary school and to discuss the effects of the results. The courseware is designed to improve the numerical concepts of the learners through many thought activities. The experiment shows effectiveness of the learning activities to improve learning numerical concepts for students with learning difficulties, categorized into two groups - an experimental group and a control group, and also it shows positive responses on improvement of their calculation ability.

This study investigated the elementary school students' ability on the algebraic reasoning as generalized arithmetic. It analyzed the written responses from 648 second graders, 688 fourth graders, and 751 sixth graders using tests probing their understanding of the properties of whole number operations. The result of this study showed that many students did not recognize the properties of operations in the problem situations, and had difficulties in applying such properties to solve the problems. Even lower graders were quite successful in using the commutative law both in addition and subtraction. However they had difficulties in using the associative and the distributive law. These difficulties remained even for upper graders. As for the associative and the distributive law, students had more difficulties in solving the problems dealing with specific numbers than those of arbitrary numbers. Given these results, this paper includes issues and implications on how to foster early algebraic reasoning ability in the elementary school.

The research goal of this study is to investigate the realities and difficulties of English education for young children of North Korean refugee mothers. The subjects of this study were 201 North Korean refugee mothers of 3-5-year-old children. They were surveyed and some of them were interviewed on their children's English education. The results of the study are as follows. First, most of the North Korean refugee mothers in this study provided their children with English education since their children were 3 years old. The major reason for the English education was their children's peer group who received English education early in their lives. Their educational interaction periods with their children were less than 10 minutes, and they had their young children study English alone, focusing solely on their assignment. Next, North Korean refugee mothers claimed that the biggest difficulties for teaching English to their children were cost, lack of information, lack of time to teach English, and unsatisfactory English education. They expressed that the cost for English education was a burden on the family to some extent.

Purpose : The goal of this study is to estimate the effect of SSP electrical stimulation applied to acupoints as conducted in oriental medicine on the swallowing function of patients with swallowing difficulties caused by stroke. Methods : Twenty-two hemiplegic stroke patients with swallowing difficulties were divided into an intervention-only group (Group I; n=11) and an intervention-SSP electrical stimulation group (Group II; n=11). Therapeutic intervention was performed on participants in the intervention-only group and the intervention-SSP electrical stimulation group, for 20 minutes per session, three times per week, for four weeks. In this study, SSP electrical stimulation to the acupoints (Cheondol, Yomchon, Budol, Pungji, and Sanyinjian) of stroke patients with swallowing difficulties was applied, and to investigate the effects of SSP electrical stimulation, Clinical dysphagia scale (CDS) and ultrasonography assessment was used to measure pre and post-intervention scores. Results : In the clinical dysphagia scale assessment, the post-intervention score for group II had significant enhancement unlike group I. In the ultrasonography assessment, the hyolaryngeal movement in group II showed significant increase in the swallowing function unlike group I. Conclusion : From the above results, significant effects came from SSP electrical stimulation of 3Hz, biphasic wave, continuous current when applied to the acupoints as conducted in oriental medicine to improve the swallowing function of stroke patients.

This study investigeted secondary math teachers' difficulties of technology in geometry class with grounded theory by Strauss and Corbin. 178 secondary math teachers attending the professional development program on technology-based geometry teaching at eight locations in January 2014, participated in this study with informed consents. Data was collected with an open-ended questionnaire survey. In line with grounded theory, open, axial and selective coding were applied to data analysis. According to the results of this study, teachers were found to experience resistance in using technology due to new learning and changes, with knowledge and awareness of technology effectively interacting to lessen such resistance. In using technology, teachers were found to go through the 'access-resistance-unaccepted use-acceptance' stages. Teachers having difficulties in using technology included the following four types: 'inaccessible, denial of acceptance, discontinuation of use, and acceptance 'These findings suggest novel perspectives towards teachers having difficulties in using technology, providing implications for teachers' professional development.

People who have hearing difficulties suffer from satisfactory mutual interaction with normal people because there are little chances of communicating each other. It is caused by rare communication of people who have hearing difficulties with normal people because majority of normal people can not understand sing language that is represented by gestures and is used by people who have hearing difficulties as a principal way of communication. In this paper, we propose a recognition method of finger language using FCM algorithm in order to be possible of communication of people who have hearing difficulties with normal people. In the proposed method, skin regions are extracted from images acquired by a camera using YCbCr and HSI color spaces and then locations of two hands are traced by applying 4-directional edge tracking algorithm on the extracted skin lesions. Final hand regions are extracted from the traced hand regions by noise removal using morphological information. The extracted final hand regions are classified and recognized by FCM algorithm. In the experiment using images of finger language acquired by a camera, we verified that the proposed method have the effect of extracting two hand regions and recognizing finger language.

In recently, attracting foreign students are very active in lots of universities of South Korea. According to trend, foreign students who are studying in Korea have increased steadily. The programs to support and help them for adaptation of the university and academic success are rising though, on account of language barrier, it seems not easy to adapt to those people who finished studying korean language training that roles incubator and entered their major. More over, to expect personal training for them by professors is also difficult because of short of educational or executive and bankroll support in reality. Therefore it became a social issue about managing foreign students of South Korea. This study aimed to analyse the difficulties of learning from chinese international student's view. For this, we analysed focus group interview which intended 16 chinese foreign students and the collected data through reflective journal record using Nvivo program. In the results of focus group interview, learning difficulties of chinese foreign students are itemized 4 sections of personal aspect, environmental aspect, educational contents' aspect and educational methodic aspect. It is subdivided 11 sections and identified of requirement for studying support corresponding each part of difficulties. This research finding will be able to expect to provide a suggestion to looking for options for learning support plan of chinese foreign students.
