This study explored the effect of ASR-based pronunciation instruction, using a mobile platform, on EFL learners' pronunciation development. Particularly, this quasi-experimental study focused on whether using mobile ASR, which provides voice-to-text feedback, can enhance the perception and production of target English consonants minimal pairs (V-B, R-L, and G-Z) of Korean EFL learners. Three intact classes of 117 Korean university students were assigned to three groups: a) ASR Group: ASR-based pronunciation instruction providing textual feedback by the mobile ASR; b) Conventional Group: conventional face-to-face pronunciation instruction providing individual oral feedback by the instructor; and the c) Hybrid Group: ASR-based pronunciation instruction plus conventional pronunciation instruction. The ANCOVA results showed that the adjusted mean score for pronunciation production post-test on the Hybrid instruction group (M=82.71, SD =3.3) was significantly higher than the Conventional group (M=62.6, SD =4.05) (p<.05).

This study aimed at investigating the effects of grouping participants in pairs according to their relative vocabulary proficiency on the incidental improvement of vocabulary knowledge. Forty six university students were divided into three groups (high-high(n=14), high-low(n=18), or low-low(n=14)) and took part in the study. They performed three vocabulary activities in pairs as extra-class works. Data were collected from one receptive vocabulary knowledge test scores before treatment and two posttest scores after treatment. The results showed that, unlike former study results, HL dyads acquired more vocabulary receptively and productively than HH or LL dyads did, which demonstrated that collaborative pair activity was conducive to the growth of vocabulary knowledge. Furthermore, not only higher proficiency participants in HL pairs made greater vocabulary gains than participants in HH pairs did but also lower proficiency participants gained more vocabulary than participants in LL pairs did. Based on these results, we discussed pedagogical implications.

Resistance to sliding (RS) between the bracket, wire, and ligature has been largely debated in orthodontics. Despite the extensive number of published studies, the lack of discussion of the methods used has led to little understanding of this phenomenon. The aim of this study was to discuss variables affecting RS in orthodontics and to suggest an operative protocol. The search included $PubMed^{(c)}$, $Medline^{(c)}$, and the Cochrane $Library^{(c)}$. References of full-text articles were manually analyzed. English-language articles published between January 2007 and January 2017 that performed an in vitro analysis of RS between the bracket, wire, and ligature were included. Study methods were analyzed based on the study design, description of materials, and experimental setup, and a protocol to standardize the testing methods was proposed. From 404 articles identified from the database search and 242 records selected from published references, 101 were eligible for the qualitative analysis, and six for the quantitative synthesis. One or more experimental parameters were incompatible and a meta-analysis was not performed. Major factors regarding the study design, materials, and experimental setup were not clearly described by most studies. The normal force, that is the force perpendicular to the sliding of the wire and one of the most relevant variable in RS, was not considered by most studies. Different variables were introduced, often acting as confounding factors. A protocol was suggested to standardize testing procedures and enhance the understanding of in vitro findings.

Background: Hemiplegic patients usually have difficulty maintaining balance. Balance training is a major component of there habilitation program for patients with neurological impairment. The purpose of this study was to investigate the effects of PLS(Posterior Leaf Spring), FES(Functional Electrical stimulation), treadmill training, and neurodevelopmental treatment on the improvement of balance in patients with hemiplegia. Methods: We looked into published studies from Dankook University’s electronic library databases of RISS4U, KMbase, NCBI, and MEDLIS concerning the effectiveness of any form of intervention leading to improvement of balance. All types of studies relevant to the topic that were published in English during the time period of 1986 to 2005 were included. Results: 1. There were significant differences in standing balance, dynamic activity balance, and gait speed between barefoot subjects and subjects who wore SPAFO and HPAFO(p<.05). 2. The changes in ROM and FRT related to sex, age, height, and weight part of the diagnosis, as well as experience relapse, was of meaningless value. Changes in ROM related to the duration of pain and experiences of falling down were also meaningless. However, FRT showed significant static differences(p<.05). 3. The body-weight-support treadmill training scoring of standing balance, step length, and a timed 10m walking test showed definite improvement. 4. The proprioceptive control approach improved dynamic balance in patients with hemiplegia. Conclusion: Consequently, further study is needed to verify methods when physical therapists are researching balance ability in hemiplegic patient.

In this paper, the features which are thought to be used by humans based on the psychological experiment of human information processing are applied to character recognition problem. Man will deal with a little large area information as well as pixel by pixel information. Therefore we define the feature that represents a little wide region I information called region feature, and combine the features derived from region feature and pixel by pixel features that have been used by now. The features we used are the result of region feature based preanalysis, mesh with region attributes, cross distance difference and gradient. The training and test data in the experiment are handwritten Korean alphabets, digits and English alphabets, which are trained on neural network using back propagation algorithm and recognition results are 90.27-93.25%, 98.00% and 79.73-85.75%, respectively Experimental results show that the feature we are suggesting in this paper is 1-2% better than UDLRH feature similar in attribute to region feature, and the tendency of misrecognition is more easily acceptable by humans.

An example-based machine translation approach is a new paradigm for resolving various problems caused by the rules of conventional rule-based machine translation. But, in pure example-based machine translation, it is very hard to find similar examples matched with input sentences by using reasonable parallel corpus. This problem causes large overheads in the process of sentence generation. This paper proposes new method of English-Korean transfer using both patterns and examples. The patterns are composed of sentence patterns and phrase patterns. Meta parts of the patterns make the example-based machine translation more practical by raising the probability to find similar examples. The use of patterns and examples can reduce the ambiguities in source language analysis and give us a high quality of MT. And experimental results with a test corpus are discussed.

Purpose: The objective of this systematic review was to assess the effects of family support programs on caregiving burden, depression, and stress in family caregivers of people with dementia. Methods: A literature search was conducted of electronic databases to identify randomized controlled studies with family support programs done between 2000 and 2014. Studies published in English and/or Korean were included for the analysis with search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group. Studies were rated for quality assessment by two independent reviewers using the appraisal checklist developed by Cochrane Reviews and Dissemination. Of 8,334 articles identified in the literature search, full texts of 76 articles that met the inclusion criteria were reviewed and 38 were found to include relevant outcomes. Results: Results from selected studies were pooled in statistical meta-analysis using Review Manager Software and heterogeneity between combined studies was assessed using the Chi-square test. Meta-analysis showed that the effect sizes of family caregiver support programs were small to medium for categories of caregiving burden (Hedge's g= - 0.17, 95% CI= - 0.30~ - 0.04), depression (Hedge's g= - 0.30, 95% CI= - 0.40~ - 0.20), and stress (Hedge's g= - 0.39, 95% CI= - 0.52~ - 0.25). Conclusion: The review results indicate that a support programs can assist family caregivers in reducing their psycho-emotional distress.

Purpose: The purpose of this study was to translate the Spiritual Perspective Scale (SPS) and Self-transcendence Scale (STS) into Korean and test the psychometric properties of the instruments with Korean elders. Methods: A cross-sectional survey design was used to implement the three stages of the study. Stage I consisted of translating and reviewing the scales by six experts. In Stage II, equivalence was tested by comparing the responses between the Korean and English versions among 71 bilingual adults. Stage III established the psychometric properties of the Korean versions SPS-K and STS-K among 154 Korean elders. Results: Cronbach's alpha of the SPS-K and the STS-K .97, and .85 respectively with Korean elders. Factor analysis showed that the SPS-K had one factor; the STS-K had four factors with one factor clearly representing self-transcendence as theorized. Both scales showed good reliability and validity for the translated Korean versions. However, continued study of the construct validity of the STS-K is needed. Conclusion: Study findings indicate that the SPS-K and the STS-K could be useful for nurses and geriatric researchers to assess a broadly defined spirituality, and to conduct research on spirituality and health among Korean elders. Use of these scales within a theory-based study may contribute to further knowledge about the role of spirituality in the health and well-being of Korean people facing health crises.

According to NIA (National Information Society Agency) report, digital divide is a vicious circle which makes quality interval of human's life between people who have information and relatively not. Especially in a smart phone society, there is a big problem between disabled people and normal people. This paper suggests a braille keyboard system for the blind to solve these problems. It is designed for portable use, convenience and quick text typing based on bluetooth communication technique. In text input test, all texts (Korean, English, number) were accurately expressed and typing speed was about 22 [c/m](characters per a minute). Especially, we design text2voice function to provide more accurate key input system. Popular applications such as call, alarm, message, kakao talk, internet, music, were performed without carring problems using the proposed braille keyboard system. The proposed technique is thought to contribute to eliminating the digital divide through the expansion of smartphone users.
