Objective: We performed a usability test for the speech therapy solutions Smart SpeechTM and Smart NasometerTM to apply usability testing results for the development of an optimal speech therapy solution. Materials and Methods: A total of 19 health professionals (12 doctors and 7 speech therapists) practicing speech therapy were recruited. They performed a usability evaluation by simulating speech therapy tasks for the speech-impaired after being familiarized with Smart Speech and Smart Nasometer for 30 minutes. The participants performed the tasks using oral training contents, breathing training contents, and vocal training contents of Smart Speech. Then, they conducted tasks of wearing Smart Nasometer and checking nasalance data measured by Smart Nasometer. Lastly, they completed a satisfaction survey of Smart Speech and Smart Nasometer. Results: The usability evaluation showed that more than 60% of the participants were satisfied with Smart Speech and more than 50% with Smart Nasometer. The participantssuggested improvements of Smart Speech in the game description, content color, guide video, audio, data analysis and management, and difficulty-level control function. Conclusion: The results of this study showed the importance of usability evaluation with users when developing healthcare devices.

It is not well understood because the Impact factor method differs from every country. Dynamic, static and pseudo-staitic field loading tests on PSC-I girder bridges were carried out to find out the dynamic property of the bridge. This paper is aimed to figure out actual dynamic property of the bridge by using field loading test. An empirical method based on impact factor is widely used and also argued. Displacement and strain response measured from the tests was compared with one from the empirical method. The former seems to be reasonable since it can consider actual response of a bridge through field tests.

Backgrounds : There have not been so many studies about the correlation of logical background between acupuncture and herbal medicine. Objectives : This study was aimed to find out the logical relationship between acupuncture points of Wushijiuyu(五十九兪) and Fangfengtongshengsan(防風通聖散) for the treatment of fever disease. Methods : I investigated the background of rationale of Wushijiuyu(五十九兪) and Fangfengtongshengsan(防風通聖散) through survey of classical text include Yellow Emperor's Classic of Medicine(.帝.經內經, Hwang Di Nei Jing), Liujing(類經), Zhenjiujiayijing(鍼灸甲乙經) and Huangdisuwenxuanmingfanglun(黃帝素問宣明方論). Results & Conclusions : The words "Wushijiuyu(五十九兪) and Wushijiuci(五十九刺)" are founded in the Yellow Emperor's Classic of Medicine(黃帝內經) are either prescription of the acupuncture points for the treatment of fever disease. However, acupuncture points of two methods are not same. According to Liujing(類經), Wushijiuyu(五十九兪) have used acupuncture points located in head, upper and lower extremities, trunk, and back. However Wushijiuci(五十九刺) just select acupuncture points of head and extremities without those of trunk and back. Acupuncture points located in yang meridian(45points) and Dumai(督脈, 5points) are significantly used more than those of yin meridian(8 points) and Renmai(任脈, 2points) in Wushijiuyu(五十九兪) and Wushijiuci(五十九刺). The distribution of acupuncture points used Wushijiuyu(五十九兪) have closer correlation with Fangfengtongshengsan(防風通聖散) than Wushijiuci(五十九刺) in the prescription.

이 연구는 치과감염에 대한 의료소비자들의 인식도를 파악하고자 대구지역 치과병원(3곳)에 내원하는 환자를 대상으로 설문조사하여 회수한 213부를 분석 하였다. 그 결과 가장 중요하게 생각하는 감염관리는 ‘기구소독’이 64.3%로 많았고, 연령에서 유의한 차이가 있었다(P<0.01). 감염관리 책임여부에 대해서는 72.3%가 ‘치과의사, 직원’의 책임이라고 답하였고 학력에서 유의하였다(P<0.001). 청결위생중요도에서는 70.0%가 ‘매우중요하다’고 답하였고, 성별(P<0.05)과 연령(P<0.01)에서 유의하게 나타났다. 치과 감염관리에 관한 정보습득 경험이 있는 사람이 없는 사람보다 손 씻기(P<0.001), 타액 흡입기 교체(P<0.001), 양치컵 교체(P<0.01)여부를 더 유심이 관찰하고, 보안경 착용여부도 더 중요하게 생각하는 것으로 조사되었다 (P<0.01). 이상의 연구결과로 치과 의료기관은 보건복지부에서 고지하는 감염관리 평가를 잘 인지하고 일반 의료소비자들의 눈높이에 맞는 감염관리를 실천한다면 병원의 신뢰도는 물론 환자만족도까지 높일 수 있는 바탕이 될 것이라 생각된다. The purpose of this study was to grasp the recognition of medical consumer over the infection in dental clinic. The study performed the questionnaire by selecting the patients visiting 3 dental clinics of Daegu area as targets and analyzed 213 question papers collected. The result revealed that the infection control, which was most important for the patients, was ‘instrument disinfection (64.3%) and it was significant in age factor(P<0.01). For the responsibility of infection control, 72.3% replied that ‘dentist or dental clinic staff’ should be responsible for it and it was significant in academic background factor(P<0.001). For the importance of cleaning and sanitation, 70.0% replied that ‘it is very important and it was gender(P<0.05)and the age factor.((P<0.01) The person who experienced the information about the infection control of dental clinic observed hand washing(P<0.001), replacement of suction tip(P<0.001) and replacement of teeth washing cup (P<0.01) more carefully and considered whether dentist wears protective goggle more importantly than the person who did not experience it(P<0.01). If dental clinic recognizes the evaluation of infection control notified by the Ministry of Health & Welfare and performs the infection control suitable for the eye level of general medical consumer on the basis of the study result above, it can improve the reliance of hospital as well as patients satisfaction.

Purpose: We developed a serious speech game for rehabilitation of the patients with dysarthria. The Smart Speech Program is composed of a three categories such as continuity, pitch, and loudness. The purpose of this study was to examine the usefulness of smart speech programs in speech therapy of patients with dysarthria by evaluating changes in voice. Methods: Fifteen patients with dysarthria disorder and without aphasia suffered from brain diseases were enrolled. The study started with “pre-evaluation 1, and then, evaluations were repeated pre-evaluation 2 after 6 weeks without any treatment in order to generated the control data. After pre-evaluation, a smart speech program was used to perform training. Post-training evaluation 1 were performed just after treatment. And, after six weeks of daily life, conducted a post-training evaluation 2 to see if treatment remained effective. The evaluation used the multi-dimensional voice program of the computerized speech laboratory to collect voice samples-pitch, intensity, fundamental frequency(F0), maximum phonation time(MPT), jitter, relative average perturbation(RAP), and the articulation parameters were measured by the Urimal Test of Articulation and Phonology(U-TAP) and the 3-Position Articulation Test. Results: In the post-training evaluation 1, pitch range(pitch max.-pitch min.), F0, intensity, MPT, jitter, RAP and U-TAP scores of all subjects showed significant results(p<0.05). In the post-training evaluation 2, significant changes were retained in pitch range and U-TAP scores, both of which had a long-term effect. Conclusions: These preliminary results suggest that the newly developed serious game for speech training has a positive effects on pitch, loudness, and articulation abilities in the patients of dysarthria. Therefore, it was found that smart speech was effective in improving speech ability and articulation of dysarthria patients.
