Purpose: By comparing daily and practical stress experienced in speech rehabilitation clinical practice per grade, our purpose is reducing clinical practical stress and researching ways of efficient practical education. Also, we want to present basic data of care and coping methods related to different stress levels. Methods: The research surveys 48 second year and 52 third year undergraduate students who are undertaking a speech rehabilitation degree at Daegu Health College from Nov, 2016 to Dec, 2016. Questionnaire consists of 5 questions related to basic stress levels (as defined by BEPSI-K) and 5 factors, 32 questions related to clinical practical stress. All sections used Likert 5 score criterion usually used in self-report questionnaire. Results: The second year students scored higher than the third year students on the ‘Frustration of Living’ and ‘Forget Something Important’ questions. However, the third year students scored higher than the second year students on the questions related to ‘Clinical Practice Instructor’. Conclusions: Further research needs to be done to determine if there is a difference between stress coping mechanisms in each grade students. Furthermore, through result of research, we are looking forward to contributing efficiency of speech rehabilitation clinical practice, suggesting guide line about how to improve practical stress.

Purpose: This study looked at speech language pathologists working environments with the direction of improvingconditions. and to find a way to combat job stress and adjustment amongst speech language pathologists. Methods: The questionnaire results of 101 speech language pathologists from all parts of Korea were analyzed. The questionnaire was organized into 64 items related to speech language pathologists, 11 items of general traits, 43 items of job stress, and 22 items about the correlation between job stress and burnout. Characteristics of the people who are subject according to the degree of job stress and burnout were also measured. Results: First, the level of job stress and exhaustion of speech language pathologists were as follows: Job stress was an average of 2.16 (±0.41) points on a four-point scale. In the case of burnout, on a five-point scale, the average was 2.41 points. Second, the difference between exhaustion and job stress of speech language pathologists were as follows: The subject properties are significant differences in job stress areas depending on the number of working days. Third, the relationship between job stress and exhaustion of speech language pathologists were as follows: Job stress and burnout correlated positively. Conclusions: The effort to improve job ability at work, which is main cause of job stress for speech language pathologists, is needed in the future. Because job stress and burnout are higher in one's first year, it should provide consideration for adaptation to the workplace and systematic education. It is hoped that the results of this study help to improve speech language pathologists' working environment by revealing the working-stress of speech language pathologists and the cause of mental burnout and proposing alternative methods.

Purpose: This study was designed to determine the characteristics of referential communication in school-age children with mild intellectual disabilities. Methods: This study consisted of two groups: 21 school-age children with mild intellectual disabilities who had the language abilities of 6- to 9-year-olds and a control group of 24 language-matched children. The two groups were compared to determine the characteristics of referential communication in school-age children with mild intellectual disabilities. Results: The listener role task of referential communication was based on communicative perspective-taking. The school-age children with mild intellectual disabilities displayed a significantly lower performance than the control group under privileged ground conditions. The speaker role task of referential communication was based on communicative perspective-taking. A significantly lower performance was observed in the school-age children with mild intellectual disabilities than the control group under baseline conditions and privileged ground conditions. In the listener role task of referential communication, the control group showed a positive correlation between the privileged ground conditions and performance intelligence quotient. However, the school-age children with mild intellectual disabilities showed no significant difference. In the speaker role task of referential communication, the school-age children with mild intellectual disabilities showed a positive correlation between baseline conditions and performance intelligence quotient.Conclusions: The results of this study indicate that school-age children with mild intellectual disabilities have lower referential communication performance than the language-matched control group. These results were influenced by factors of communication such as perspective-taking conditions and showed lower performance in privilege ground conditions.

This study was to see the effects of the barrier game reinforcing difference strategy on referential communication skill of children with hearing impairment. The purpose of this study was to see if this intervention can improve clarification request as listeners and explanation performance ability by speakers which are required to overcome the problem occurring when children with hearing impairment stop communicating. The subjects were 3 children with hearing impairment and these 3 children have language ability of four years old or older and normal intellectuality. This study applied multiple probe baseline across the subjects to see the effects and instrument for assessment designed by researcher was used to assess and compare baseline, intervention, follow-up.   The results of this study were as follows.   First, the barrier game reinforcing difference strategy improved all the subjects clarification request ability as listeners. Before the intervention, the communication stopped because the subjects, as listeners, didnt know how to respond to speakers inadequate information and they didnt show clarification request either. However, after the intervention, the subjects clarification request as audience increased and their acquisition remained in time. Second, the barrier game reinforcing difference strategy improved all the subjects explanation ability as speakers. Before the intervention, the subjects had difficulty understanding the referential information on listeners response and responding appropriately. But, after the intervention, referential communication skill pointing out and explaining listeners failed response improved and the effects of acquisition stayed.   As described above, it can be said that the barrier game reinforcing difference strategy has a positive influence on the referential communication skill of children with hearing impairment.

It is important to consider children’s whole-word productions as a measure of phonological development. The purpose of this study is to estimate whole-word abilities in two-year-old children. Four measurements to look at whole-words were proposed: the proportion of whole-word correctness (PWC); the phonological mean length ofutterance (PMLU); the proportion of whole-word proximity (PWP); and the proportion of whole-word variability (PWV). Approximately 40-50 minutes of communication data were collected for each child using play materials and picture cards. The results were as follows: First, PWC is mean .43; PMLU is mean 6.60; PWP is mean .85; and PWV is .40. Second, there were high positive correlations between the percentage of consonants correct (PCC) and PWC, PMLU, PWP, but negative correlations between PCC and PWV. Third, there were corrections between allmeasurements. These measures were relatively easy to apply and should prove to be highly valid and reliable. Fourth, suggested stage by Ingram (2000) is to develop a means to place children into phonological developmental stages based on their whole-word productions. The PMLU score of target words places in stage Ⅴ.

Specific language impairment is closely related to reading disability. The double-deficit hypothesis is very effective in explaining the characteristics of reading disabilities in the Korean language. In the double-deficit hypothesis, the major factors of reading disabilities, phonological awareness and naming speed, were analyzed to provide the mediation strategy to improve the early reading ability for children with specific language impairment.The double-deficit hypothesis can also explain the possibilities that children with specific language impairment will show both a defect of phonological awareness and naming speed, and therefore will have reading disability. In both groups in this study, phonological awareness and naming speed were predicting factors for reading ability and this supported the double-deficit hypothesis. Therefore a phonological awareness training program at the syllable level on syllable blending and the mediation strategy of naming speed on naming speed of numbers should be applied for children with deficits in both phonological awareness and naming speed.

The purpose of this study was to investigate cohesion markers and the number of subordinate clauses from school-aged children with severe stuttering. In order to examine the narrative ability of school-aged children with severe stuttering, the present study asked the two groups to retell a story and made a group comparison of the length of story, the number of subordinate clauses, and cohesion markers. The first group consisted of 10 children who stutter while the second group consisted of 10 age-matched normally fluent children. The results of the study were as follows. First, there was no significant difference in story length between the two groups. However, a significant difference was found between the two groups in terms of the average number of words per C-unit and the number of subordinate clauses per C-unit. Second, there was a significant difference between the two groups in terms of the number of cohesion markers (conjunctions and connective endings). These results suggest that pragmatic aspects need to be considered in the intervention of school-aged children with severe stuttering.

김시영(Si Young Kim),황하정(Ha Jeong Hwang) 한국언어치료학회 2016 한국언어치료학회 학술발표대회 논문집 Vol.2016 No.12

Purpose: This study analyzes how pathology students" overall satisfaction with their clinical practice differs based on the setting. This study especially focuses on cases of clinical practice that are conducted on-campus and off-campus. Methods: This research was conducted in September 2015 on a group of speech therapy major students in a university at Daegu. These students are baccalaureate candidates who have already completed their required speech therapy clinical practice education. All responses were guaranteed anonymity and students were given the option to opt out of the survey whenever they chose to. Responses were done individually without intervention from professors or supervisors. A total of 60 surveys were passed out, and 58 were returned back, of which 3 were considered invalid. Results: For on-campus practices, the mean overall satisfaction was 3.77 and for off-campus practices, the mean overall satisfaction was 3.83. The results of this study are aimed to allow speech therapy students to find an effective ratio of on-campus and off-campus clinical practices that maximizes satisfaction. Conclusions: When looking at subcategories, students were most satisfied with the content and instructor during on-campus clinical practice. For off-campus practice, students were most satisfied with the environment, time/evaluation, and post-clinical practice change. This research aims to provide a foundation for quality improvement in clinical practice education and students" abilities in clinical performance, as well as contribute to fostering a professional speech therapist. Further research calls for clinical practice that is both satisfactory in the content and ratio of on and off-campus practice, and the creation of training methods that allows for more active participation during clinical practices.
