Purpose: The purpose of this study was to examine the relationship between eating disorders and parent-adolescent communication in middle school students. Method: There were 267 adolescents taken as participants from two middle schools in rural areas. Data were collected from June to July 2005, using the Eating Disorder Inventory-2 questionnaire (23 items) and Parent-Adolescent Communication Inventory (10 items for open family communication, 10 items for problem in family communication). The SPSS Win version 12.0 was used for descriptive analysis, t-test, and partial correlation coefficient. Result: The mean score on the eating disorder was 2.74 (range: 1-6). Meanwhile, the mean scores on the parent-adolescent communication was 3.37 (range: 1-5). There were significant differences in eating disorders according to gender, age, negative perception of the participant's body weight, family's perception of obesity, diet experiences, and BMI. Eating disorders showed a significant negative correlation with parent-adolescent communication. Conclusion: In this study, there was a significant negative correlation between eating disorders and parent-adolescent communication. In order to prevent an eating disorder, education and training to enhance communication skills should be provided to adolescents and their parents as well.

Voice is the most common means for communication, but some people have difficulties in generating voice due to their congenital or acquired disorders. Individuals with speech disorders might lose their speaking ability due to hearing impairment, encephalopathy or cerebral palsy accompanied by motor skill impairments, or autism caused by mental problems. However, they have needs for communication, so some of them use various types of AAC (Augmentative & Alternative Communication) devices in order to meet their communication needs. In this paper, a mobile application for literate people having speech disorder was designed and implemented by developing accurate and fast sentence-completion functions for efficient user interaction. From a user study and the previous study on Korean text-based communication for adults having difficulty in speech communication, we identified functionality and usability requirements. Specifically, the user interface with scanning features was designed by considering the users' motor skills in using the touch-screen of a mobile device. Finally, we conducted the usability test for the application. The results of the usability test show that the application is easy to learn and efficient to use in communication with people with speech disorders.

연구 목적：소아를 다루는 임상의들에게 관찰되는 가장 흔한 발달상의 문제 중 하나는 언어 지연이다. 언어 발달은 주변 환경의 자극에 영향을 받게 되는데, 환경과의 상호 작용에는 아동 자신의 기질 또한 중요한 요소로 작용한다. 기질 연구의 가설에 의하면 아동의 고유한 행동 양식은 상당 부분 타고난 것이며, 이것이 향후 발달에 큰 영향을 미친다고 알려져 있는데, 아동의 기질과 언어 지연과의 관계에 대한 연구는 활발치 않아, 본 연구는 한국에서 의사 소통 장애를 가진 아동에서 어떤 기질 특성이 있는지를 밝히고자 했다. 방 법：환자군은 DSM-IV 진단 기준에 의해 의사 소통 장애라고 진단되고, 전반적 발달 장애, 정신 지체, 언어 운동 장애 혹은 감각 장애를 갖지 않은 세 살에서 일곱 살 사이의 아동 20명을 대상으로 하고 정상대조군은 상기 장애를 갖지 않는 50명을 대상으로 하여 어머니에게 한국판 '부모 기질 설문(Parental Temperamental Questionnaire)'을 완성하도록 하여 기질을 측정하였다. 기질의 9가지 범주 및 요인 A점수를 비교하기 위하여 비모수적 통계법을 사용하였으며, 아동들의 기질 진단을 비교하기 위하여 Chi-square통계법을 사용하였다. 결 과：의사 소통 장애를 가진 아동들에서 정상 아동들에 비해 기분의 범주는 통계적으로 유의하게 낮았고, 반응의 강도의 범주는 통계적으로 유의하게 높았다. 기질 진단 면에서는 두 집단은 통계적으로 유의한 차이를 보이지 않았지만 의사 소통 장애를 가진 아동들이 양육 곤란형에 가까운 집단에 더 많이 포함되었다. 결 론：이와 같은 결과는 의사 소통 장애를 가진 아동들에 특징적인 기질 양상이 있음을 시사한다. 기질양상의 조기 발견은 부모들에게 의사 소통 장애 아동들의 발달학적 특성을 이해하고 이들에게 적절한 양육을 제공하는데 도움을 줄 것이다.

Social (pragmatic) communication disorder (SCD) is a new diagnosis included under communication disorders in the neurodevelopmental disorders section of Diagnostic and Statistical Manual of Mental Disorders-5. SCD is defined as a primary deficit in the social use of nonverbal and verbal communication. SCD has very much in common with pragmatic language impairment, which is characterized by difficulties in understanding and using language in context and following the social rules of language, despite relative strengths in word knowledge and grammar. SCD and Autism Spectrum Disorder (ASD) are similar in that they both involve deficits in social communication skills, however individuals with SCD do not demonstrate restricted interests, repetitive behaviors, insistence on sameness, or sensory abnormalities. It is essential to rule out a diagnosis of ASD by verifying the lack of these additional symptoms, current or past. The criteria for SCD are qualitatively different from those of ASD and are not equivalent to those of mild ASD. It is clinically important that SCD should be differentiated from high-functioning ASD (such as Asperger syndrome) and nonverbal learning disabilities. The ultimate goals are the refinement of the conceptualization, development and validation of assessment tools and interventions, and obtaining a comprehensive understanding of the shared and unique etiologic factors for SCD in relation to those of other neurodevelopmental disorders.

A voice is one of the most significant non-verbal elements for communication. Disorders in vocal organs, or habitual muscular setting for articulatory cause vocal disorders. Therefore, by analyzing the vocal disorders, it is possible to predicate vocal diseases. In this paper, a method of predicting vocal disorders using the jitter, shimmer, and harmonics-to-noise ratio (HNR) extracted from vocal records is proposed. In order to extract jitter, shimmer, and HNR, one-second's voice signals are recorded in 44.1khz. In an experiment, 151 voice records are collected. The collected data set is clustered using cobweb clustering method. 21 classes with 12 leaves are resulted from the data set. According to the semantics of jitter, shimmer, and HNR, the class whose centroid has lowest jitter and shimmer, and highest HNR becomes the normal vocal group. The risk of vocal disorders can be predicted by measuring the distance and direction between the centroids.

The cerebral microvessels possess barrier characteristics which are tightly sealed excluding many toxic substances and protecting neural tissues. The specialized blood-neural barriers as well as the cerebral microvascular barrier are recognized in the retina, inner ear, spinal cord, and cerebrospinal fluid. Microvascular endothelial cells in the brain closely interact with other components such as astrocytes, pericytes, perivascular microglia and neurons to form functional 'neurovascular unit'. Communication between endothelial cells and other surrounding cells enhances the barrier functions, consequently resulting in maintenance and elaboration of proper brain homeostasis. Furthermore, the disruption of the neurovascular unit is closely involved in cerebrovascular disorders. In this review, we focus on the location and function of these various blood-neural barriers, and the importance of the cell-to-cell communication for development and maintenance of the barrier integrity at the neurovascular unit. We also demonstrate the close relation between the alteration of the blood-neural barriers and cerebrovascular disorders.

Purpose: The purpose of this study was to investigate variations in velar shape according to age, sex, and race using magnetic resonance imaging (MRI). Materials and Methods: The study sample consisted of 170 participants (85 children, 85 adults) between 4 and 34 years of age. Velar morphology was visually classified using midsagittal MRI scans for each participant by 2 independent raters. Inter- and intra-rater reliability was assessed. Statistical analyses were performed to identify correlations of velar shape with sex, age, and race. Results: The most frequent velar shape was "butt" for both adults(41%) and children (58%) in this study. The least common shapes for adults were "leaf" and "S." The children did not exhibit any "leaf" or "straight" velar shapes. A statistically significant difference was noted for age with respect to velar shape (P=0.014). Sex and race were found to have no significant impact on velar shape in this study. Conclusion: When using MRI to evaluate velar morphology, the "butt" shape was most common in both children and adults. Velar shape varied significantly with age, while race and sex did not have a significant impact.

Objective: This systematic review aimed to evaluate periodontal parameters in orthodontically tractioned teeth compared with the respective non-tractioned contralateral teeth. Methods: Search strategies were developed for six electronic databases and gray literature. Random-effects meta-analyses were performed for the outcomes of interest. Furthermore, the certainty of the evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) tool. Results: Overall, 2,082 articles were identified, of which 24 were selected for the qualitative synthesis. A significant difference was observed between the impacted and contralateral teeth (mean difference [MD] = 0.25; 95% confidence interval [CI] = 0.10-0.40; I² = 0%) when the gingival index was evaluated. Additionally, impacted teeth showed a greater probing depth, with a significant mean difference between the groups (MD = 0.14; 95% CI = 0.07-0.20; I² = 6%). Most studies had a low risk of bias; however, the certainty of the evidence was very low owing to the design of existing studies. Conclusions: The evidence in the literature indicated that tractioned teeth might show worsening of periodontal parameters related to the gingival index and probing depth; however, the evidence remains uncertain about this outcome. Furthermore, probing depth should be considered regarding its clinical significance because of the small effect size observed.

This study aimed to systematically review the available body awareness interventions in patients with musculoskeletal disorders. A total of 3,462 studies were searched in relevant databases using the search keywords, and six studies that met the selection criteria after review were included in the final analysis. The qualitative level of the studies was classified using the five levels of evidence-based classification, and systematic analysis was conducted according to PICO model (patient/population, intervention, comparison and outcomes). Of the six studies included in the final analysis, there were one, three, and two randomized controlled trials, non-randomized two-group studies, and case reports, respectively. Body awareness therapy was applied to patients with idiopathic scoliosis, non-specific musculoskeletal disorder, hip osteoarthritis, and amputation, who showed positive improvements after the interventions. Our results suggested that body awareness therapy is an important intervention with positive effects on the recovery of patients with musculoskeletal disorders.
