  • 이중 부등호를 이용한 여러 실험을 통해 부적 일치 효과(negative compatibility effect: NCE)가 일관적으로 관찰되었다. 그러나 왜 이 현상이 발생하는가에 대해서는 몇 가지 서로 다른 가설이 제기되어 왔다. 본 연구에서는 부적 일치 효과의 발생 원인으로 가정되어 온 자동 억제, 정보의 업데이트 및 하향적 통제 등과 같은 요인들의 타당성을 확인하고자 하였다. 색이 다른 이중 부등호로 구성된, 차폐된 점화자극과 목표자극의 배열에 대해서 목표자극인 부등호의 방향에 대해 판단하는 경우에, 참가자들은 부등호의 방향과 손의 반응이 일관적인 과제 (실험 1), 부등호의 방향과 손의 반응이 반대인 과제 (실험 2)에서는 물론, 색 반응 과제 (실험 3) 에서도 방향에 근거한 부적 일치 효과를 나타냈다. 이 결과는 부적 일치효과의 주된 원인이 지각적 우세성이나 자극과 반응 사이의 본질적 속성에서 기인할 수 있음을 시사한다.

  • Objective To investigate the effect of upper limb rehabilitation combining robot with low-frequency repetitive transcranial magnetic stimulation (rTMS) on unilateral spatial neglect in stroke patients. Methods Patients who had hemispatial neglect after right hemisphere stroke were randomly divided into rTMS only group, robot only group, and combined group. All groups received conventional neglect therapy and additional treatment for each group. rTMS group received rTMS therapy. Robot group received robot therapy, while combined group received both therapies. The effect of therapy was assessed with Motor-Free Visual Perception Test-3 (MVPT-3), line bisection test, star cancellation test, Catherine Bergego Scale (CBS), Mini-Mental State Examination (MMSE), and the Korean version of Modified Barthel Index (K-MBI). These measurements were evaluated before and after treatment. Results For each group, 10 patients were recruited. There were no significant differences in baseline characteristics or initial values among the three groups. Two weeks after the therapy, all groups showed significant improvement in MVPT-3, line bisection test, star cancellation test, CBS, MMSE, and K-MBI. However, changes in measurements showed no significant differences among groups. Conclusion Treatment effect of the combined therapy of robotic therapy and low-frequency rTMS therapy for hemispatial neglect was not statistically different from that of each single treatment. Results of this study did not prove the superiority of any of the three treatments. Further study with large number of patients is needed to evaluate the superiority of these treatments.

  • A study for service quality is actively done but that for the quality level of the provided service recognized by the service provider for the same service, and for the difference in quality level of service use recognized by the service user is not relatively widely done. Thus, this study analyzed difference between the quality level of the provided service recognized by the service provider and the quality level of service use recognized by the service user, around administrative service as one of cores of the university service, and examined how difference between both service qualities have effect on business the business satisfaction level of the service provider. We measured the service level provided by the individual in charge of the administrative service of the A-university and examined the service quality in business by use of questionnaires. As the result, it was appeared that the quality level of the provided service recognized by the service provider for the same service quality was higher than the quality level of service use recognized by the service user. In addition, it was found that the quality level of the provided service recognized by the service provider had a significant effect on the service provider's business satisfaction level but the quality level of service use recognized by the service user had not effect on the business satisfaction level of the provider.

  • 맥락에 대한 의미적인 처리가 암묵기억의 수행에 어떠한 영향을 주는지에 관해서는 상반된 의견이 존재한다. 전이적합성처리 이론에 의하면 암묵기억은 지각적 처리에 주로 의존하기 때문에 맥락에 대한 의미처리가 기억수행에 영향을 미치지 않아야 한다(예, Blaxton, 1989). 반면 의미-특정적 이론에 의하면 암묵기억에서도 부호화 시 제시된 의미적 맥락에 대한 처리가 이루어지기 때문에 맥락에 대한 지각적 처리와 의미적 처리 모두 암묵기억 과제의 수행에 영향을 줄 것으로 예상한다(Lewandowsky 등, 1989). 본 연구는 부호화 시 혹은 부호화 시와 인출 시 제시되었던 맥락에 대한 의미적인 처리가 암묵기억의 과제 수행에 어떠한 영향을 미치는지 알아보기 위하여 실시되었다. 실험 1과 2에서는 우세 혹은 비우세 의미맥락을 지닌 동음이의어를 이용하여 학습 시와 검사 시의 맥락의 의미적 처리가 암묵기억 및 외현기억에 미치는 효과를 알아보았다. 그 결과 학습과 검사 시의 의미맥락의 변화는 외현기억의 수행에 영향을 주는 것으로 나타났으나 암묵기억 검사에서는 수행상의 차이를 보이지 않았다. 실험 3과 4에서는 Jacoby(1991)의. 처리-해리 절차를 사용하여 실험 1과 2 각각의 과제에서 통제처리와 자동처리의 효과를 분리하여 측정하였다. 그 결과, 암묵기억 검사 시 맥락 단서로 문장이 사용되면 통제처리의 영향이 증가됨을 보였으며, 이는 암묵기억의 요소 중에 의식적으로 통제되어 처리되는 부분은 의미적 맥락에 민감하게 영향을 받고 있음을 의미한다.

  • Background and Objective The purpose of this study is to report the effect of voice therapy using the voice reinforcement method (VRM) in patients with vocal nodules. It is one of the holistic voice therapy methods for improving vocal mechanisms. VRM includes not only direct and indirect voice therapy, but also trial therapy and self-practice. Composed of four stages: vocal hygiene education, relaxation, reinforcement, and generalization. Materials and Methods The subjects were 13 patients who were diagnosed with vocal nodules. Acoustic analysis, auditory perceptual assessment, K-VHI-10 and nodules size were compared before and after voice therapy. Voice therapy was conducted by speech-language pathologist and the mean number was 4.2. Results In acoustic analysis, Jitter, vF0, vAm, Shimmer, NHR, and VTI were significantly decreased. F0 was increased after voice therapy for women. 'Grade', 'Rough,' and 'Breathy' were significantly decreased in the GRBAS scale after voice therapy. In addition, K-VHI-10 and nodules size were significantly decreased. Conclusion VRM seems to be an effective voice therapy method in vocal nodules treatment. In VRM, especially, trial therapy is given motivation for vocal nodules treatments and self-practice has a continuous therapeutic effect in everyday life. VRM can be also applied to the voice therapy for other hyper-functional dysphonia.

  • Background and Objectives : Bowing of the vocal fold, a bowed edge of the vocal fold results from various disorder causes glottic incompetence resulting in voice disorders. The results of treatment were not satisfactory even though a variety of methods of treatment were applied. The goal of this study is to evaluate of efficacy of the non-surgical, voice therapy in patients with vocal fold bowing. Materials and Method : Twenty two patients of vocal fold bowing not resulting from vocal fold palsy and sulcus vocalis were analyzed. After voice therapy and medical treatment, parameters of perceptual, acoustic, aerodynamic analysis and stroboscopic findings were compared those of pretreatment results. Results and Conclusion : Jitter, shimmer and maximal phonation time were significantly improved and subjective satisfaction was improved in 73% of patients. In the videostroboscopic examination, vocal fold gap was decreased in 27% of patents. The result of this study indicates that voice therapy alone has effect in treatment of vocal fold bowing. Voice therapy is one of the mainstay of treatment of vocal fold bowing.

  • This study explored the perception of transplanted English prosody by thirty American and Korean, male and female listeners. The English utterances of various sentence types produced by Korean and American male speakers were employed to transplant the American prosody contours to Korean English utterances. Then, the thirty subjects were instructed to rate the transplanted prosodic components. Results showed that the interactions between the three factors (e.g., rater groups & transplantation types; transplantation types & sentence types; rater groups & transplantation types & sentence types) turned out to be meaningful. Both Americans and Koreans perceived the effectiveness of the combined effect of transplanted duration and pitch or duration and pitch and intensity. However, when perceiving individual prosodic components, Americans and Koreans showed different perceptual ratings. As for the overall prosody change, Americans perceived the change of intensity in a significant way but Koreans did not because intensity is not a crucial semantic factor in Korean. Americans rated the transplantation of duration alone as ineffective while Koreans rated otherwise. This was explained by the difference between English and Korean. The difference of perspective was also significant with different sentence types, especially with the three sentence types that had speech rates slower than other sentence types. A slower speech rate intensified the mismatch between the transplanted duration and the original pitch causing a negative impression on American listeners whereas this did not affect Korean listeners. Pedagogical implications of the findings are discussed.

  • The purpose of this study was to review of mechanism and application methodology about mental practice. The mental practice is symbolic rehearsal of physical activity in the absence of any gross muscular movements. Human have the ability to generate mental correlates of perceptual and motor events without any triggering external stimulus, a function known as imagery, Practice produces both internal and external sensory consequences which are thought to be essential for learning to occur, It is for this reason that mental practice, rehearsal of skill in imagination rather than by overt physical activity, has intrigued theorists, especially those interested in cognitive process. Several studies in sport psychology have shown that mental practice can be effective in optimizing the execution of movements in athletes and help novice learner in the incremental acquisition of new skilled behaviors. There are many theories of mental practice for explaining the positive effect In skill learning and performance. Most tenable theories are symbolic learning theory, psyconeuromuscular theory, Paivio's theory, regional cerebral blood flow theory, motivation theory, modeling theory, mental and muscle movement nodes theory, insight theory, selective attention theory, and attention-arousal set theory etc.. The factors for influencing to effects of mental practice are application form, application period, time for length of the mental practice, number of repetition, existence of physical practice.
