In this study, we reported the validation results of the Korean Affective Voice Database (KAV DB), an affective voice database available for scientific and clinical use, comprising a total of 113 validated affective voice stimuli. The KAV DB includes audio-recordings of two actors (one male and one female), each uttering 10 semantically neutral sentences with the intention to convey six different affective states (happiness, anger, fear, sadness, surprise, and neutral). The database was organized into three separate voice stimulus sets in order to validate the KAV DB. Participants rated the stimuli on six rating scales corresponding to the six targeted affective states by using a 100 horizontal visual analog scale. The KAV DB showed high internal consistency for voice stimuli (Cronbach's α=.847). The database had high sensitivity (mean=82.8%) and specificity (mean=83.8%). The KAV DB is expected to be useful for both academic research and clinical purposes in the field of communication disorders. The KAV DB is available for download at https://kav-db.notion.site/KAV-DB-75 39a36abe2e414ebf4a50d80436b41a.

The purpose of the this study is to observe the effects of healthy adults' age on temporal features of speech and identify which could differentiate older and young adults. We examined speech rates(i.e., overall speaking rate, articulation rate), occurrence of pause, and duration of pause per utterance by utilizing the National Institute of Korean Language's open corpus. We selected a total of 30 healthy adults (10 young, 10 middle-aged, and 10 older adults) in this study. There were significant differences among the groups in the overall speaking rate, articulation rate, total occurrence of pause, the occurrence of pause between syntactic words, total duration of pause, and duration of pause between syntactic words. The older and middle-aged adults showed slower speech rates and longer and more frequent pause than young adults. But there were no significant differences among the three groups in terms of pause within syntactic word. The overall speaking rate significantly differentiated older adults from young adults. These findings suggested that the effect of speakers' age was reflected in gradual changes in the temporal features of their speech.

Background and Objectives : Quality of life(QOL) is a construct representing physical, mental and social well-being. QOL has been used as a device for measuring the severity of health-related condition and treatment outcomes. As the social welfare system develops, the attention to QOL increases as well. The aims of this study was to examine whether the patients with voice disorder perceived significantly more the effects of voice disorder on QOL than nonpatient group did and if any, identify the sociodemographic risk factors influencing QOL of patients. Materials and Methods : This study asked 113 adults with voice disorders who were enrolled in Voice Clinic in the Department of Otolaryngology, Kangbuk Samsung Hospital between lune 1998 and January 1999 and 111 nonpatients to complete a questionnaire designed to elicit information about the effete of voice disorders on quality of lift. The questionnaire included items concerning sociodemographic areas, voice symptoms, job, effects of voice disorders on QOL domains(work, social, psychological, physical, and communication areas), potential risk factors to exposures, familial and medical history of voice disorders. Results : The sociodemographic characteristics of the patient group are as follows : (1) 75.2% of total patient group were female and the rest were male. (2) Age of total patient group ranged from 20 to 65 years. Hoarseness was the most commonly reported complaints, followed by complaints of high note difficulties during singing and voice fatigue. The patient group perceived effects of voice disorders on the areas of work, social, psychological, physical and communication more adversely than the comparison group did (p＜0.05). QOL impairments were evaluated as a function of age, gender, education, and income, controlling other independent effects. The results were that (1) age was significantly associated with work problems and (2) gender and income were significantly associated with psychological problems. Conclusions : The findings indicated that the patients with voice disorders would perceive markedly adverse effect on all QOL domains, that is, work, social, psychological, physical, communicational areas. Therefore, the results of study suggest that lurker investigations about the nature of voice disorders, the prevention, treatment, and coping strategies are needed in the future.

This study aims to identify the relations between self-reported symptoms of industrial workers work-related musculoskeletal disorders and psychosocial factors. The subjects of the study were 120 male workers who were using the rehabilitation center of K company and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from eighteen subjects whose responses were insincere and who had disorders in musculoskeletal areas, the responses of 102 ones were decided for the final analysis. The results showed that there were significant differences in self-reported symptoms of work-related musculoskeletal disorders between the subjects according to smoking, physical burden and self-efficacy. To prevent and control work-related musculoskeletal disorders, multi-characteristic aspects of how the disorders appeared and psychological factors, in particular, self-efficacy, should be carefully considered. Then, as psychosocial factors affect musculoskeletal disorders, relations between the disorders and factors should be analysed through long-term follow-up studies, psychosocial factors should be actively intervened, and the effect should be evaluated.

Purpose: The purpose of this study was to identify the influencing factors on eating disorders in college students. Method: A descriptive correlational study design was used. Eight hundred fifty-nine college students were administered self-report questionnaires to examine eating habits, self-efficacy, depression, and parent-adolescent communication from May to June, 2010. Collected data were analyzed by the SPSS 15.0 program for t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Result: The level of an eating disorder in participants was moderate and it differed by gender, major, and type of living. The eating disorder showed a significant correlation with self-efficacy (r=-.28, p=<.000), depression (r=.23, p=.001), and parents-adolescent communication (r=-.13, p=.008). Self-efficacy (8.2%) and depression (2.1%) were significant predictors to explain the eating disorder. Conclusion: This study provides comprehensive understanding of the influencing factors on eating disorders in college students. It suggests that nursing interventions to improve self-efficacy and decrease depression for management of eating disorder are needed.

Articulation disorders are characterized by an inability to achieve clear pronunciation due to misuse of the articulators. In this paper, a method of detecting such disorders by comparing to the standard pronunciations is proposed. This method defines the standard pronunciations from the speeches of normal children by clustering them with three features which are the Linear Predictive Cepstral Coefficient (LPCC), the Mel-Frequency Cepstral Coefficient (MFCC), and the Relative Spectral Analysis Perceptual Linear Prediction (RASTA-PLP). By calculating the distance between the centroid of the standard pronunciation and the inputted pronunciation, disordered speech whose features locates outside the cluster is detected. 89 children (58 of normal children and 31 of children with disorders) were recruited. 35 U-TAP test words were selected and each word's standard pronunciation is made from normal children and compared to each pronunciation of children with disorders. In the experiments, the pronunciations with disorders were successfully distinguished from the standard pronunciations.

This study explores the relationship between childhood abuse experiences and subsequent mental disorders in adults, with a particular focus on the moderating role of spiritual well-being. Using self-reported data from 210 graduate students in the Daejeon and Chungcheong regions, the findings demonstrate that spiritual well-being significantly moderate how childhood abuse impacts adult mental health. Specifically, individuals with lower levels of spiritual well-being experience a greater exacerbation of metnal disorders related to past abuse, while those with higher levels show a buffering effect. These results suggest that enhancing spiritual well-being could be a vital component of therapeutic interventions aimed at preventing mental disorders in adults who have experienced childhood abuse. We highlight the potential benefits of incorporating spiritual well-being into mental health strategies and call for additional research to substantiate these findings across broader populations. This unique contribution underscores the importance of considering spiritual factors int the therpeutic process, offering a new and valuable perspective in the field of mental health research.

This study is generally purposed to develop a mobile augmentative and alternative communication system (hereinafter referred to as 'a mobile AAC system'). Also the device is aimed as a mobile AAC system for helping communication of persons who suffer from speech disorders in a free and convenient manner. One thing firstly considered for a successful AAC system is selection of vocabularies. For this purpose, the above researchers collected utterances in actual situations to select vocabularies of higher frequencies. For generation of sentences by maximizing the use of limited space in the AAC system, this study specifically presents a method of predicting predictions. This method includes selecting vocabulary and classifying it by domains so as to meet the characteristics of the mobile AAC communication, using a noun thesaurus for semantic analysis, and building a sub-category dictionary. Predicting predicates by selecting symbols in accordance with this method is tested and the utility thereof is confirmed.
