Background and Objectives : The aim of this study is to introduce Korea version of pediatric VHI and to compare pVHI-K scores between children with dysphonia and children without voice problems before pVHI-K is developed as a preliminary study. Additionally, the relationship between pVHI and acoustic measures were investigated. Materials and Methods : pVHI-K scores in normal group were obtained from 15 parents who have children with no present or past history of a voice disorder, hearing loss, or related disability that can affect the their voice or speech. Dysphonia group consisted of 15 parents who have children with bilateral vocal fold nodule's at Department of Otolaryngology, the Seoul National University Hospital (SNUH). pVHI-K and acoustic parameters were measured in two group. Results : The mean pVHI scores (total, functional, physical, emotional) in normal group were 2.33 (T), 0.80 (F) 1.33 (P) and 0.27 (E), respectively whereas those of pVHI in children group with dysphonia were 23.13 (T), 11.07 (F), 5.73 (P) and 6.13 (E), respectively and significant differences were revealed in total pVHI score as well as in all of the sub-pVHI scores. Moreover, significant correlation between pVHI-K parameters (T, F, P) and acoustic measures [Shimmer(%)] were shown in children in dysphonia group. Conclusion : Reported by parents can be useful as a supplementary clinical tool for diagnosing and measuring treatment effectiveness in young children with dysphonia.

Objectives: The purpose of this study was to investigate the associated factors of self-reported dry mouth in adults. Methods: A self-reported questionnaire was filled out by 249 adults in Seoul and Gyeonggi-do from June to October, 2014. The questionnaire consisted of general characteristics of the subjects, age, monthly income, smoking, alcohol drinking, and systemic diseases including systemic diseases, medication, oral health status, and stress. The question for dry mouth consisted of dryness in skin, eyes, lips, and nasal mucosa. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.881 in the study. Oral health related quality of life (OHIP-14) was adapted from Yoon. The questionnaire for OHIP-14 included functional limitation, physical pain, psychological disability, social disability, and experience in hadicap measured by Likert 5 scale. Cronbach's alpha was 0.885 in the study. Data was analyzed for a t-test, one-way ANOVA and multiple regression analysis by using SPSS(SPSS 18.0, USA) program. Results: There were positive correlations between oral health-related quality of life and self-reported dry mouth (functional limitation r=0.288, physical pain r=0.219, psychological discomfort r=0.193, physical disability r=0.280, psychological disability r=0.205, social disability r=0.224 and handicap r=0.270). In the multiple regression analysis, variation of self-reported dry mouth were positively associated with dry eyes{very often(${\beta}=0.305$)), sometimes(${\beta}=0.186$)}, dryness on lips{very often(${\beta}=0.247$), sometimes(${\beta}=0.177$)}, handicap(${\beta}=0.152$), physical disability(${\beta}=0.128$) and alcohol drinking(1-2 times/week)(${\beta}=0.116$) (p<0.001). Conclusions: Self-reported dry mouth may cause deterioration of the entire body dryness(dryness on eyes and lips), low oral health-related quality of life(handicap and physical disability) and alcohol drinking. Thus, It is necessary to develop oral health education programs to prevent and manage dry mouth in adults.

For recently 2 years, 3 cases of esophageal achalasia were surgically treated by modified Heller operation with gastric fundoplication. Esophageal achalasia is functional disorder of lower esophagus of which symptoms are dysphasia, regurgitation, and weight loss. Preoperative diagnosis was made by clinical manifestations and radiologic examination, esophagoscopy and confirmed at operative table. Operative procedures are variable, but modified Heller operation is common method to handicap reflux esophagitis and postoperative esophageal stricture. Now, our patients who were surgically treated were well alive without complaining of specific symptoms for followed period.

Based on 2009 Korea Health Panel, this study investigated socio-economic and clinical characteristics associated with emergency medical transport use, and analyzed a simple predictive model of emergency medical transport use. Analysis results were summarized as follows: First, emergency medical transports such as 119 ambulance were more used than private cars, taxis, or walk-in. Second, between a user group and a non-user group of emergency medical transports, there were statistically significant differences in age, the level of education, family composition, house type, household income, the relationship with the head of household, insurance types, the presence of handicap, the presence of chronic disease, reasons to emergency medical service use, and treatment after emergency medical service completed. Third, age, household income, the presence of handicap, reasons to emergency medical service use, and treatment after emergency medical service completed were statistically significant predictors associated with emergency medical transports use. To improve emergency medical service system, the characteristics and predictors associated with emergency medical transports are more concerned.

Since the enactment of "Mobility Promotion Law for Transportation Vulnerable", each municipality has been various efforts to improve the transportation vulnerable's the right of movement. However, the effectiveness of mobility promotion policy for the transportation vulnerable is awfully inadequate because circumstances which associated with operation of transportation of the handicapped such as local conditions and transport characteristics have not been considered. Thus, in this study investigated traffic characteristics of the transportation vulnerable through the data of regional slope, non-step buses and handicap vehicles operating conditions and so on in Busan Metropolitan. Also, we proposed to introduction of the 'mobility index' which is based on local condition analysis of Busan. And we suggested that how to improve the convenience of transportation vulnerable's movement.

The purpose of this study was to construct a grounded theory as the basis for developing future nursing interventions by describing and analyzing the holistic lives of the physically handicapped adolescents. The subjects were 10 physically handicapped adolescents who were attending a rehabilitation school located in Kyunggi region and could understand and respond to the questions. The aim and purpose of the study were explained to the subjects, and only those who accepted to participate in the study were selected as the actual study subjects. The study data were collected from July to November 2000. The investigators provided detailed explanations to the subjects about keeping the anonymity of the subjects name and confidentiality of the information provided by the study subjects. The subjects received in-depth interviews by the investigators. Each interview took about 40 minutes to 1 hour and 30 minutes, and each subject received interviews with the range of one to 3 times. All interviews were recorded under the permission of the subjects. The investigators formed field notes after finishing each interview. In the process of data analysis, 'realizing the difficulty due to physical handicap' was found to be the causal condition, whereas' acceptance of physical handicap' was identified as the context. Then, we identified' awaring as the valuable being' as the core phenomenon, 'support from family and social group and spiritual help' as the intervening condition, 'effort for adaptation' as the strategy, and' finding the meaning of life' as the consequence. Through the theoretical model derived from this study, an important aspect the lives of physically handicapped adolescences was identified that' awaring as the valuable being' help them cope better and find the meaning of life in spite of suffering they experience.
