Objectives : The purpose of this study is to report the clinical effectiveness of herbal remedies (Bokryeongkamcho -tang. Yeongkyechulkam-tang.) on nummular eczema. Methods : The 49 year-old male patient has been suffered from nummular eczema for 8 months. At first, he was treated with Bokryeongkamcho-tang for 56 days. And then he was treated with Yeongkyechulkam-tang for last 40 days. During the treatment we checked pruritis degree changes and extent changes by asking. And we checked how prulent exudates, crusts, scratch marks are changes by taking photos. First evaluation was performed before treatment, second evaluation was performed after taking Bokryeongkamcho-tang 56 days, third evaluation was performed after taking Yeongkyechulkam-tang 40 days. Results : After taking Bokryeongkamcho-tang 56 days, pruritus was decreased and prulent exudents were stopped, and crusts were disappeared. Nummular eczema on trunk, arm, thigh was disappeared. But light pruritis was still going on, and small circle-shaped vesicles groups were lagged on forearm and shin, ankle. So we found other symptoms from the patient, and administered Yeongkyechulkam-tang. After taking Yeongkyechulkam-tang 40 days, pruritus was almost decreased and nummular eczema on fore arm, shin was disappeared. Conclusions : This clinical case indicates that herbal remedies(Bokryeongkamcho-tang. Yeongkyechulkam-tang.) are effective on nummular eczema.

In clinical clerkships, residents function as trainees, workers, and teachers for other medical students. Although residents care for patients in harsh environments and encounter precarious patient-safety situations, they are working towards becoming competent specialists. Residency education programs are very important in cultivating specialists able to adapt to the rapidly-changing medical environment, and are also necessary to improve the quality of specialist training. Competent specialists not only need clinical competency, but also a wide range of abilities including professionalism, leadership, effective communication, cooperation, and attention to continuous professional development/continuing medical education activities. Each Korean association of specialties has its own educational goals and standardized education programs to help residents learn specific techniques and competencies related to medical care for patients, though the training environment of each residency is different within each trainee hospital. Although it is also important to evaluate residency education programs, currently there is only an examination of knowledge and assessment of skills based on mini-clinical evaluation exercises or direct observation of procedural skills. In order to develop an objective and estimable evaluation tool that can assess the overall achievement level within each training course, it is necessary to evaluate the knowledge, skills, and attitudes of residents. Residency education programs need further attention and reform.

In this paper, we describe the composition of frequency response bands based on experimental data of plants (controlled systems) with uncertainty and nonlinearity, and the robust stability evaluation of feedback control systems. Analysis and design of control systems using the upper and lower bounds of such experimental data would be effective as a practicable method which is not heavily dependent upon mathematical models such as the transfer function. First, we present a method to composite gain characteristic bands of frequency response of cascade connected plants with uncertainty and a recurrent inequality for the composition. Next, evaluation methods of the robust stability of multi-loop control systems obtained through feedback from the output terminals and multi-loop control systems obtained through feedback into the input terminals are described. In actual control systems, experimental data of frequency responses often depends on the amplitude of input. Therefore, we present the evaluation method of the nominal value and the width of the frequency response band in such a case, and finally give numerical examples based on virtual experimental data.

This study aims to evaluate the student's satisfaction of clinical performance examination(CPX) and self-assessment in Korean medical curriculum. A questionnaire was given to clinical clerkship students of Pusan National University School of Korean medicine in this study. The items in this questionnaire covered overall evaluation of guidelines, module & learning environment, standardized patients, and self-assessment in CPX. Most of all students recognized CPX as a more effective learning method than any other method. Most students were satisfied with the module & learning environment, standardized patients, and self-assessment except the satisfaction for guidelines relationally. The results of this study demonstrated that the students had a high level of satisfaction in CPX. This study shows that CPX has been implemented into the Korean medical curriculum.

In this paper, a highly effective learning model that can be applied to the 7th level-based curriculum, which will begin in high schools in the year 2002, will be proposed. Two learning models that have different perspectives on dividing the students into level groups(diagnostic evaluation model and formative evaluation model) were introduced, and teaching materials for each model were developed. After applying the teaching materials to actual classes, the achievement rate of the students was analyzed. According to the results of this research, the achievement rate of students is affected by the point of time at which they are divided into level groups, and formative evaluation proved to be the superior learning model dividing students into level groups.

Various interaction techniques have been studied for providing the feeling of touch and improve immersion in augmented reality (AR) environments. Tangible AR interaction exploiting two types (product-type and pointer-type) of simple objects has earned great interest for cost-effective design evaluation of digital handheld products. When the sizes of markers attached to the objects are kept big to obtain better marker recognition, the pointer-type object frequently and significantly occludes the product-type object, which deteriorates natural visualization and level of immersion in an AR environment. In this paper, in order to overcome such problems, we propose tangible AR interaction using fingertip touch combined with small-sized markers. The proposed approach facilitates the use of convex polygons to recover the boundaries of AR markers which are partially occluded. It also properly enlarges the pattern area of each AR marker to reduce the sizes of AR markers without sacrificing the quality of marker detection. We empirically verified the quality of the proposed approach, and applied it in the process of design evaluation of digital products. From experimental results, we found that the approach is comparably accurate enough to be applied to the design evaluation process and tangible enough to provide a pseudo feeling of manipulating virtual products with human hands.
