본 논문은 멀티미디어 교육자료와 전통적 수업방식의 효과성을 실질적으로 검증하고자 전문계 고등학교의 수업 방법을 비교분석하였다. 실업계의 전문교과 중 유통관리실무과목을 학습내용으로 선정하고, 멀티미디어 교육자료를 MS파워포인트로 디지털화하였다. 이를 위하여 30명의 학생들을 각각 실험집단과 통제집단의 표본집단으로 하고 동질성과 학업성취도를 고려하여 구성하였다. 동일한 교사가 두 집단을 같은 자료로 가르쳤다. 차이점은 두 집단간의 전달방법인데 두 유형의 교수방법으로 학습효과성과 만족도를 분석하기 위하여 사후검증을 실시하였다. 방법은 사전검사 점수를 공변인으로 통제한 후, 학생들의 학업성취도 사후검사 점수를 종속변인으로 공변량분석을 수행하였으며, 결과는 집단 간에 통계적으로 유의미한 차이가 있었다.(F=5.06, p<.05). 그것은 멀티미디어 교육자료를 활용한 수업의 학업성취도가 교과서 위주의 전통적 설명식 수업보다 더 높은 것으로 나타났다. 수업방식에 대한 만족도는 실험 통제집단 검증에서 통계적으로 유의미한 차이가 나타났다(t=5.65, p<.001). 따라서 멀티미디어 교육자료를 활용한 실험집단의 수업방식이 전통적 수업방식을 적용한 통제집단 보다 수업성취도와 만족도 측면에서 더 높은 것으로 나타났다.

장애인의 직업재활에 있어서 제도적 환경적 개선노력과 더불어 심리적 요소들을 다루는 일이 매우 중요하게 된다. 사실 많은 수의 사람들이 심리적 적응상의 문제로 인하여 적절한 직업을 갖지 못하고 있거나 직장생활의 지속이 어렵게 된다. 일은 장애인 개인의 존엄성을 놓이고 사회에 대한 창조적 기여를 가능하게 할 뿐만 아니라 가족기능을 회복시켜 장애를 지니지 않은 다른 가족 구성원들의 자유와 능력을 신장시키는 효과적인 수단이자 도구이지만 지금까지 이들의 진로개발이나 직업개발에 있어 동기부여와 흥미요소의 고려가 부족하였다. 따라서 장애 특히 중증의 장애를 지닌 시민들이 효과적으로 이용할 수 있는 그림검사, 특히 그립 흥미검사 도구의 개발이 시급하고 이를 위한 초기 과정으로서 흥미검사의 구성개념을 분석하고 그 개념의 타당도를 검증하려는 노력이 본 연구의 토대이다 연구결과 정신적 심상은 발달장애인의 학습과정을 촉진시키며, 그림 자극이 재인 수행에 영향을 미치는 것으로 나타났다. 연구에서 얻은 결론은 여러 가지 검사도구에서 채택하고 있는 Holland의 여섯 가지 분류방식에 많은 임상적, 경험적 연구들이 이루어졌으며, 괄목할만한 경과를 나타내었다는 점이다. 따라서 이러한 이론에 기초할 때 직업탐색과 진로상담에 필요한 정보와 자료들의 실제적 활용가능성은 매우 높다고 될 수 있다. 인지적 장애를 지니거나 독해력과 읽기 능력이 제한된 사람들에게 효과적으로 사용 될 수 있는 흥미탐구 검사는 지금까지 임상에서 사용되고 있는 흥미검사 도구들의 유용성을 감안할 때 Holland방식의 직업분류에 따른 항목들의 개발이 보다 적적할 것으로 보인다.

Physical therapists have been using balance and weight shifting training to induce improvements in standing and walking. This study compared the effects of kinetic feedback frequency and concurrent kinetic feedback on the performance and learning of a weight shifting skill in young, nondisabled adults. Sixteen young adults without known impairment of the neuromusculoskeletal system volunteered for the study. Subjects in each of three kinetic feedback groups performed a weight shifting task in an attempt to minimize error between their effort and a center of pressure (COP) template for a 12 second period. Feedback was provided: 1) concurrently (concurrent feedback), 2) after each trial (100% feedback), 3) after every other trial (50% feedback). Immediate and delayed (24 hour) retention tests were performed without feedback. During acquisition phase, the concurrent feedback group exhibited less error than either of the post response feedback group. For the immediate retention test, the 50% feedback group exhibited less error than did the 100% feedback and concurrent feedback. During the delayed retention, 50% feedback group displayed less error than did the other groups. But no significant differences were found between groups. These results suggest that practice with concurrent feedback is beneficial for the immediate performance, but not for the learning of this weight shifting skill. Lower frequency of feedback resulted in more permanent changes in the subject's ability to complete the task.

Repetitive transcranial magnetic stimulation (rTMS) modulates cortical excitability beyond the duration of the rTMS trains themselves. Depending on rTMS parameters, a lasting inhibition or facilitation of cortical excitability can be induced. Therefore, rTMS of high or low frequency over motor cortex may change certain aspects of motor learning performance and cortical activation. This study investigated the effect of high and low frequency subthreshold rTMS applied to the motor cortex on motor learning of sequential finger movements and brain activation using functional MRI (fMRI). Three healthy right-handed subjects (mean age 23.3) were enrolled. All subjects were trained with sequences of seven-digit rapid sequential finger movements, 30 minutes per day for 5 consecutive days using their left hand. 10 Hz (high frequency) and 1 Hz (low frequency) trains of rTMS with 80% of resting motor threshold and sham stimulation were applied for each subject during the period of motor learning. rTMS was delivered on the scalp over the right primary motor cortex using a figure-eight shaped coil and a Rapid(R) stimulator with two Booster Modules (Magstim Co. Ltd, UK). Functional MRI (fMRI) was performed on a 3T ISOL Forte scanner before and after training in all subjects (35 slices per one brain volume TR/TE = 3000/30 ms, Flip angle $60^{\circ}$, FOV 220 mm, $64{\times}64$ matrix, slice thickness 4 mm). Response time (RT) and target scores (TS) of sequential finger movements were monitored during the training period and fMRl scanning. All subjects showed decreased RT and increased TS which reflecting learning effects over the training session. The subject who received high frequency rTMS showed better performance in TS and RT than those of the subjects with low frequency or sham stimulation of rTMS. In fMRI, the subject who received high frequency rTMS showed increased activation of primary motor cortex, premotor, and medial cerebellar areas after the motor sequence learning after the training, but the subject with low frequency rTMS showed decreased activation in above areas. High frequency subthreshold rTMS on the motor cortex may facilitate the excitability of motor cortex and improve the performance of motor sequence learning in normal subject.

Within physical therapy education, there has been increased attention to curricula and course that emphasize problem solving, clinical reasoning, and synthesis of information across traditional discipline-specific boundaries. This article describes the development implementation, and outcomes of a problem-based learning course in Physical therapy. The course was designed to help students to integrate the various elements of a physical therapy curriculum and to enhance their abilities to respond to an ever-changing health care environment. An evaluation of the course by the first 50 students who completed it revealed both strengths and weaknesses. Students responded that the course enhanced their professional behavior, including interpersonal communication skills, team work, and follow-through with professional responsibilities. The learning package was developed by the authors and implemented to a college students during three weeks of the first semester of 2001. Most studies which conducted PBL module development were short period or temporary PBL package application and evaluation rather than a whole semester's. While, this study carried on partial integrated PBL curriculum development and application with recomposing content of the two subjects to one subject Physical therapy which includes four PBL packages. This package was developed from a simple concept to complex and partial integrated PBL curriculum application systematically variable learning methods such as discussion, practice, lecture, video. There are 2 classes, each class has 25 students, in the college. Each class has 5 small groups consisting 5 students. Two tutors proceeded discussion charging each class also, they used multiple methods and materials like tutorials, self-directed learning, lecture, and video. The package is 5 grades and 5 hours per week and the rate of discussion, lecture is 4, 1 respectively. One of the most change is the increase of interaction between students and tutors. Whenever students need information and suggestion, they can visit tutors who provide reading materials and guide for the direction of self learning. Therefore, this study describes the PBL package development process and application during one semester recomposing contents of two subjects to Physical therapy concepts. Besides, it will contribute to active application of existing each subject to tutors who intend to convert as PBL methods. The study has significant meaning to show potentiality of partially integrated PBL application, using systematic PBL package development from two subjects contents. However, when students' need of yearning is over the extent of Introduction of Physical therapy and Rehabilitation medicine, tutors should set learning extent. So, there is limitation to attain completely integrated PBL education within one subject, therefore, it is high lighted to proceed development of integrated curriculum to maximize learning effects of PBL. It is exected that partial integrated PBL package development and application will distribute to prosper excellent physiotherapist in practice.

Gold nanoparticles have recognized a promising drug carriers in many diseases. These nanoparticles could carry anti-inflammatory drugs in the case of muscle injury and for fatigue relief. On the other hand, specific surface of this kind of nanoparticles could be critical in amount of drug they could carry. Therefore, in this study, we explore different methodology and influencing parameters on the specific surface of gold nanoparticles. After specifying the main parameters, different machine learning and artificial neural network are adopted to model the effects of different parameters. Furthermore, response surface methodology is utilized to obtain a quadrilateral relationship between different parameters and specific surface. The results indicate that concentration of the gold salt solution is the most important parameter in increasing the size of gold nanoparticle and, as a consequence, increasing specific surface. Moreover, the ability of gold nanoparticles in prolonging retention of the drugs is discussed in detail.

Tack coat is a thin layer of asphalt between the existing pavement and asphalt overlay. During construction, insufficient tack coat layering can later cause surface defects such as slippage, shoving, and rutting. This paper proposed a method for tack coat inspection improvement using an unmanned aerial vehicle (UAV) and deep learning neural network for automatic non-uniform assessment of the applied tack coat area. In this method, the drone-captured images are exploited for assessment using a combination of Mask R-CNN and Grey Level Co-occurrence Matrix (GLCM). Mask R-CNN is utilized to detect the tack coat region and segment the region of interest from the surroundings. GLCM is used to analyze the texture of the segmented region and measure the uniformity and non-uniformity of the tack coat on the existing pavements. The results of the field experiment showed both the intersection over union of Mask R-CNN and the non-uniformity measured by GLCM were promising with respect to their accuracy. The proposed method is automatic and cost-efficient, which would be of value to state Departments of Transportation for better management of their work in pavement construction and rehabilitation.
