This study was to analyzed the subject's overview and satisfaction with regards to Clinical Observation and Clinical Treatment Practice. Graduates and current students that completed one or more semesters of Clinical Observation and Clinical Treatment Practice were surveyed. A survey was conducted to 80 graduates and 78 current students. The research findings revealed that most of them have practiced treating thres patients, and was found out that language development disorder was the most common type disorder among their patients. The relationship between the subjects and the patients' parents was good. It was found that the subjects' average satisfaction with Clinical Treatment Practice was 3.60, which all was above the average. However, there will be more efforts need to enhance their satisfaction. Based on these research findings, the paper suggests that clinical supervisors have to seek more enhanced clinical practice systems and guidance methods.

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.

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.

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.

본 연구에서는 연결재(커플러)로 결합된 라이저의 외부흐름에 따른 3차원 유동-구조 연동해석을 수행하였다. 두 가지 연결재(평면 커플러, 곡면 커플러)를 고려하였으며 ANSYS CFX를 사용하여 수치해석을 수행하였다. 유동해석에서 유동공간은 유입구, 유출구와 대칭 경계조건으로 구성되었으며 연결재의 형상에 따른 항력계수와 유속분포 결과를 비교하였다. 구조해석에서는 라이저의 응답(최대 변위 및 최대 등가응력)을 통해 연결재의 유용성을 확인하였다. This study presents a 3-dimensional flow-structure interaction analysis of subsea risers in water flows. Two structural connectors (flat and circular couplers) were intentionally devised and numerically tested using ANSYS CFX to investigate how these couplers behave under the water flows. In the flow analysis, the water field was constructed with an inlet, outlet, and symmetric boundary conditions. As a result, the responses (drag coefficients and pressure fields) were obtained and the pressure fields were applied for the structural analysis. Finally, the structural responses (displacements and equivalent stresses) of the risers were measured to demonstrate the efficiency of the riser connectors.

심층수 취수용 해저 라이저의 흐름 응답 해석

해양에서 생산되는 에너지는 물론 수자원이 육지로 운반되는 과정에서 라이저의 안정성은 중요하다. 해양환경에서 이들 구조물이 받는 외력은 종종 예측하기 어려우며 안정한 해역에서도 수압을 비롯한 다양한 외력을 고려해야한다. 또한 외력으로 인해 발생하는 손상은 라이저에 치명적으로 작용할 수 있으므로 외력에 저항하는 설계가 필요하다. 파이프의 연결부위인 이음부가 외력에 취약하므로 이를 해석대상으로 이음부가 있는 경우와 없는 경우를 비교하였다. 이음부에 에폭시 접착제를 도포하여 모재 전체를 감싸는 형태를 고안하여 이를 3차원으로 모델링하였다. 라이저는 수직으로 거치되며 외관 길이의 변화를 두며 유속변화에 따른 횡하중이 작용하는 라이저의 변위와 응력에 대한 응답해석을 수행하였다. It is known that the stability of subsea risers is significant when the risers transport deep sea water to lands. In marine environment, it is hard to predict or estimate external forces on the risers. Also, the damage occurred by external forces can be severely extended into structural instability; hence, the structural design should be carefully carried out. Especially, the structural members connecting pipes are critically weak against external forces so that in the study we investigated the structural responses of the connecting members in water flows. For the purpose, 3D finite element models were constructed by introducing a connecting method, which adopted adhesive epoxy. Finally, considering various water flows the displacements and stresses were obtained and compared.
