Objective : The purpose of this study is to provide an evidence for clinical practice by systemic analysis on occupational therapy interventions for improvement of children's play. Methods : Articles used in this study were collected from database of Pubmed, ProQuest, EBSCOhost, Scopus, RISS, KISS, and National Library of Korea. The key words used in the search were "Play AND Occupational Therapy AND (Intervention OR Treatment)" and the publication period was limited from January 2007 to April 2017. 11 articles in total were selected for the systematic review analysis. Results : The results revealed that the majority of studies was one-group non-randomized study and the majority of intervention used was play-based intervention in case of that play itself was the intervention goal. The most frequently used environment for the intervention was parallel setting of home and treatment room. The majority of studies was for children with ADHD and the most commonly used assessment tool was Test of Playfulness (ToP). Dependent variables measured along with play were language skills, social interactive skills, communication and pragmatic skills, problem-solving skills, caregiver responsiveness, and parent-child interaction. Conclusion : This study help to understand the current state of occupational therapy intervention for improvement of children's play. Starting with the understanding, it is expected that various studies on play of children will be done in the future.

This survey was to identify voice symptoms and vocal-health service related experiences of occupational voice users(teachers, telemarketers, speech therapists). The 91.8% of teachers, 97.9% of telemarketers, 86% of speech therapists surveyed reported more than one voice symptom. The symptoms were classified as 9 categories(running a temperature, getting dry, dry and cough, pain, phlegm, tingled, hoarseness, cracks, swollen) and the most frequently reported from 3 groups was 'getting dry'. The 85.7% of teachers, 87.8% of telemarketers, 66% of therapists surveyed had no experience of vocal-health related services. The 19.6%, 19.9%, and 72% of each group reported they have heard both of 'voice/speech therapist'. The 36.8% of teachers and 43.6% of telemarketers answered they don't know how to use their voice efficiently and 45.3% of the teachers, 43.6% of the telemarketers, 28% of the therapists surveyed asked professional help for their voice. The result showed that most of the occupational voice users surveyed experienced voice symptoms but rarely knew professional vocal-health related services.

KBG syndrome is a rare neurodevelopmental disorder characterized by intellectual disability, skeletal anomalies, short stature, craniofacial dysmorphism, and macrodontia. ANKRD11 gene mutation and 16q24.3 microdeletion have been reported to cause KBG syndrome. Here, we report two patients with ANKRD11 mutations who initially presented with neurologic symptoms such as developmental delay and seizures. Patient 1 was a 23-month-old boy who presented with a global developmental delay. Language delay was the most dominant feature. He had hypertelorism, hearing impairment, and behavior problems characterized as hyperactivity. A c.1903_1907delAAACA (p.Lys635GInfsTer26) mutation in ANKRD11 was identified with diagnostic exome sequencing. Patient 2 was a 14-month-old boy with developmental delay and seizure. He also had atrial septum defect, and ventricular septal defect. Generalized tonic seizures began at the age of 8 months. Electroencephalography showed generalized sharp and slow wave pattern. Seizures did not respond to antiepileptic drugs. A loss of function mutation c.5350_5351delTC (p.ser1784HisfsTer12) in ANKRD11 was identified with diagnostic exome sequencing. In both cases, characteristic features of KBG syndrome such as short stature or macrodontia, were absent, and they visited the hospital due to neurological symptoms. These findings suggest that more patients with mild phenotypes of KBG syndrome are being recognized with advances in diagnostic exome sequencing genetic technologies.

The aim of this study is to prepare basic data that can be used for evaluation and intervention by investigating the characteristics of diphthongs produced by children with speech sound disorders. To confirm this, two groups of 10 children each, with and without speech sound disorders were asked to imitate the meaningless two-syllable 'diphthongs + da'. The slope of F1 and F2, amount of change of formant, and duration of glide were analyzed by Praat (version 6.1.16). As a result, the difference between the two groups was found in the slope of F1 of /ju/. Children with speech sound disorders had smaller changes in formants and shorter duration time values compared to normal children, and there were statistically significant differences. The amount of change in formant in the glide was found in F1 of /ju, jɛ/, F2 of /jɑ, jɛ/, and there were significant differences in the duration of glide in /ju, jɛ/. The results of this study showed that the range of articulation of diphthongs in children with speech sound disorders is relatively smaller than that of normal children, thus the time it takes to articulate was reduced. These results suggest that the range of articulation and acoustic analysis should be further investigated for evaluation and intervention regarding diphthongs of children with speech sound disorders.

Aphasia is a language disorder that results from brain damage and typically occurs after a stroke. The purpose of this case report was to describe the effects of Korean medical treatment on anomic aphasia after a putaminal hemorrhage. We used Korean medical treatment, including head acupuncture and herbal medicine (Hyungbangsabaek-san) therapy, on a patient who was admitted to the hospital for 19 days. The clinical symptoms were assessed with the Korean version of the Western Aphasia Battery (K-WAB), and quality of life was evaluated with Korean version of Stroke and Aphasia Quality of Life Scale-39 (K-SAQOL-39). After 19 days of treatment, the K-WAB scores were increased from 17 to 19 in the spontaneous speech score, from 7.55 to 9.85 in the comprehension score, from 9 to 9.4 in the speaking score, and from 5.8 to 9.7 in the naming score. The AQ score was increased from 78.7 to 95.9, and the K-SAQOL-3 score was increased from 2.64 to 3.26. In conclusion, the study findings suggested that Korean medical treatment could be an effective option for treating symptoms and improving quality of life in patients with aphasia after stroke.

This study focuses on the issue of automatic severity classification of dysarthric speakers based on speech intelligibility. Speech intelligibility is a complex measure that is affected by the features of multiple speech dimensions. However, most previous studies are restricted to using features from a single speech dimension. To effectively capture the characteristics of the speech disorder, we extracted features of multiple speech dimensions: voice quality, prosody, and pronunciation. Voice quality consists of jitter, shimmer, Harmonic to Noise Ratio (HNR), number of voice breaks, and degree of voice breaks. Prosody includes speech rate (total duration, speech duration, speaking rate, articulation rate), pitch (F0 mean/std/min/max/med/25quartile/75 quartile), and rhythm (%V, deltas, Varcos, rPVIs, nPVIs). Pronunciation contains Percentage of Correct Phonemes (Percentage of Correct Consonants/Vowels/Total phonemes) and degree of vowel distortion (Vowel Space Area, Formant Centralized Ratio, Vowel Articulatory Index, F2-Ratio). Experiments were conducted using various feature combinations. The experimental results indicate that using features from all three speech dimensions gives the best result, with a 80.15 F1-score, compared to using features from just one or two speech dimensions. The result implies voice quality, prosody, and pronunciation features should all be considered in automatic severity classification of dysarthria.

This thesis discussed the status of women workers as wage laborers and home laborers and the valid of a documentary movie for representing women laborers through a documentary movie, Weabak that revolved around Home-ever occupation strike leaded E-Land labor union at 30th June, 2007. Jobs for women labors got covered by the flow of flexibility with the policy of labor flexibility in South Korea during 1990s. The reasons that justify this trend are their position in the households, and their roles in working places are not very important because there are not required difficult skills. The mass dismissal which caused the E-Land strike also shared these ideologies. In Weabak, since women laborers were always expected to care for their family, they were need strikes in their home as well as their working place. However, a household is a basement for them to get the identity as a women laborer. It has two ambivalent meanings, as a protected area and disorder for them to pursue their life at the same time. Identity of Women laborers, domestic laborers as well as wage laborers, are very difficult to identify as a general noun, a laborer. Weabak is an important example to show us the possibility of a documentary as searching new realism for representing women laborers' story using their own perspective.

Objectives : The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). Methods : A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. Results : Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.05). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.05). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. Conclusion : Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.

In the Andes regions of Latin America continents, groups of diverse native tribes are intensively distributed.Among these tribes, the Aymara compose the most representative group of natives along with the Quechua. Especially, the Aymara who are concentrated on the border areas of Peru and Bolivia centered on Lake Titicaca have pursued common identity forming the same cultural area although they belong to different nations. In the meantime, the Aymara have maintained a sense of fellowship while emphasizing historicity and specialty, which are differentiated with groups of other natives based on a language constituting identity of the tribe. However, recently, focused on Puno State as the center of the border areas of both countries, the tribe's conflicts come to the surface. After being divided by the artificial boundary line, which was formed in the course of building modern countries after the independence, natives of Latin America started to emphasize differences simultaneously with cultural similarity in the frame of cooperation and competition. Together with the historical contexts, lately, focused on the border areas of Peru and Bolivia, as the same tribe came to be bound by the frameworks of different nations respectively, a new tribal conflict is being developed. Though the Aymara unite emphasizing cultural and historical specialty and recognizing them as one tribe, when they conflict with each other over inner interest, a tendency to form the identity of differentiation and distinction appeared even in the inside of the tribe. Usually, disorder between tribes seems to be originated from intertribal strife, which coexists in one region. In case of the Aymara of Peru and Bolivia, centered on Puno State where both countries maintain the border, an aspect that the fellowship of the tribe, which was established through old history changes into conflict structures by realistic conditions comes out. In understanding this point, this study analyzed the historical origin of the conflict of the Aymara and the deepened cause of the tribal disorder.

This study aimed to investigate the effects of vocal aerobic treatment (VAT) on the improvement of voice in patients with voice disorders. Twenty patients (13 males, 7 females) were diagnosed with voice disorders on the basis of videostroboscopy and voice evaluations. Acoustic evaluation was performed with the Multidimensional voice program (MDVP) and Voice Range Profile (VRP) of Computerized Speech Lab (CSL), and aerodynamic evaluation with PAS (Phonatory Aerodynamic System). The changes in F0, Jitter, Shimmer, and NHR before and after treatment were measured by MDVP. F0 range and Energy range were measured with VRP before and after treatment, and the changes in Expiratory Volume (FVC), Phonation Time (PHOT), Mean Expiratory Airflow (MEAF), Mean Peak Air Pressure (MPAP), and Aerodynamic Efficiency (AEFF) with PAS. Videostroboscopy was performed to evaluate the regularity, symmetry, mucosal wave, and amplitude changes of both vocal cords before and after treatment. Voice therapy was performed once a week for each patient using the VAT program in a holistic voice therapy approach. The average number of treatments per patient was 6.5. In the MDVP, Jitter, Shimmer, and NHR showed statistically significant decreases (p < .001, p < .01, p < .05). VRP results showed that Hz and semitones in the frequency range improved significantly after treatment (p < .01, p < .05), as did PAS, FVC, and PHOT (p < .01, p < .001). The results for videostroboscopy, functional voice disorder, laryngopharyngeal reflux, and benign vocal fold lesions were normal. Thus, the VAT program was found to be effective in improving the acoustic and aerodynamic aspects of the voice of patients with voice disorders. In future studies, the effect of VAT on the same group of voice disorders should be studied. It is also necessary to investigate subjective voice improvement and objective voice improvement. Furthermore, it is necessary to examine the effects of VAT in professional voice users.
