As technology rapidly develops, the demand for manpower by new industries is increasing. In order to respond to the changing demands of the workforce, universities are actively introducing interdisciplinary majors, which is a program formed by two or more departments cooperating to develop new majors. Although the importance of the interdisciplinary major is increasing, universities have difficulties managing them due to non-flexible educational systems. The purpose of this study is to present an effective management direction for interdisciplinary majors based on the results of a survey on student satisfaction with interdisciplinary majors. Also, we analyzed the required level and possessed level of the IS practitioners' competencies, and developed specific educational directions for training IS talents. The results showed that there was a significant difference in satisfaction with the curriculum development and curriculum evaluation of existing subjects provided by existing departments and new subjects established of interdisciplinary majors, specifically the satisfaction of new subjects is higher than existing subjects. In the IS field, there was a high demand for education in the following areas, in order: information security, information technology strategy planning, information technology operation, information technology development, information technology management, information technology sales, and core competencies. Based on the results of the analysis, the satisfaction of students and the cultivation of the talents that the interdisciplinary major aims to develop can be improved.

The second telemetry is designed for supplying additional function which the first telemetry system doesn't have and as a part system of the External Management System (EMS). It makes a patient and an animal move more freely with wireless communication at a distance of free activity from the PC and can get most data from the first telemetry to send to the PC. Recently, our laboratory is developing a RF system for the second telemetry.

For the aritificial heart valve, two types of valves-polymer and mechanical valve- are generally used. The polymer valve is used as a new low-cost artificial valve. Among the several properties of the artificial valve, the low-regurgitation property is important because it can provide better cardiac output characteristic. So in this study we analyzed and compared the regurgitation property of the mechanical valve which is generally used nowdays and the polymer valve which was made in our group. As results, the polymer valve showed the better regurgitation property compared to the mechanical valve approximately by 3 times, and increased the cardiac output by 10%.

Objective This study aims to understand the actual utilization of the oriental rehabilitation medicine center of the initial interdisciplinary medical care at the National Rehabilitation Center and to arrange proper development plans for more effective interdisciplinary medical services for future activation of interdisciplinary medical care. Method: The interdisciplinary patient status, composition of patient care, and major disease-related status were studied and analyzed for oriental rehabilitation medication relating to interdisciplinary medical care at the National Rehabilitation Center. Furthermore, the interdisciplinary status and its operating conditions were evaluated to devise a development plan for the National Rehabilitation Center. Results: As a result of the analysis of oriental rehabilitation medical care diagnosing status utilization at the National Rehabilitation Center regarding interdisciplinary medical care, the ratio of the number of those receiving interdisciplinary oriental rehabilitation medical care was less than half of the total receiving interdisciplinary care. As the major disease status from the patients of interdisciplinary care, stroke patients covered the large majority, and musculoskeletal pain patients covered the majority of outpatients. The establishment of additional oriental medication departments and assigning of interdisciplinary coordinators were presented as the goals of a development plan for the manpower and structural side of interdisciplinary medical care at the National Rehabilitation Center. On the institutional and systematic side, improvement in the interdisciplinary hierarchy and interdisciplinary model development based on the number of patients per disease was proposed. In addition, operation on ward bedding and construction of interdisciplinary EMR medical care is necessary on the medical and administration service side. Conclusion: To understand the actual utilization and to arrange development plans aimed at constructing a safe and effective interdisciplinary hierarchy for interdisciplinary medical care at the National Rehabilitation Center, patient-centered care needs to be implemented.

한국형 양심실 보조 인공 심장의 효율 측정 방법과 측정 결과이다. 한국형 양심실 보조 인공 심장은 에너지 변환기로 브러시 없는 직류 모터를 사용한다 이 브러시 없는 직류 모터가 기어 열을 따라 원추운동을 하며 혈액주머니에 힘을 가하게 되고. 이 힘에 의해 혈액주머니 안의 혈액이 박출하게 된다. 효율 측정을 위하여 제어기 및 모터부, 기어부 및 작동기부. 혈액주머니 및 기타부 등 크게 세 부분으로 나누었으며. 각각을 다시 소자별로 나누어 입. 출력의 효율을 측정했다. 부하의 토크, 분당 회전수 각속도, 인가되는 전압 등을 바꾸어 가면서 시스템의 효율을 측정했고. 이 측정을 통해서 모터 운동시의 전체적인 효율과 부분별 효율을 알 수 있었다. 특히 양심실 보조 장치의 모터부와 작동기부의 효율측정에 중점을 두었다. 측정 결과 이동 작동기형 양심실 보조 장치의 평균 동작 영역인 4$\ell/min$ 박출량에서, 전체 효율은 8 %정도이며 구체적으로는 모터부 50 %, 작동기부 85 % 혈액주머니부 19 %정도의 효율을 보였다. 또한 6$\ell/min$ 박출량의 경우, 전체 효율은 5.5 %정도였다. 분석된 결과를 바탕으로 효율을 개선하기 위해 박출량에 따른 필요 구동 전압을 결정하고. 혈액주머니의 충만 상태에 따른 속도 파형을 연구. 제안하였다.

We tested the capability of Pointwise Correlation Dimension(PD2), Approximate Entropy (ApEn) and LZ complexity, as alternative measures of a biological signal. For this purpose, we analyzed standard data and a healthy child's 24-hour heart rate variability. Our conclusion is as follows. First, PD2, ApEn and LZ complexity can be used for discerning chaotic attractor, white noise, and periodic signal. Second, these measures show different characteristics on day and night. Third, these measures can be used for detecting time-varying characteristics of biological signals.

Airway wall thickness is an important bio-marker for evaluation of pulmonary diseases such as stenosis, bronchiectasis. Nevertheless, an image-based analysis of the airway tree can provide precise and valuable airway size information, quantitative measurement of airway wall thickness in CT images involves various sources of error and uncertainty. So we have developed an accurate airway wall measurement technique for small airways with three-dimensional (3-D) approach. To illustrate performance of these techniques, we used airway phantom that consisted of 4 acryl tubes with various inner and outer diameters. Results show that evaluation of interpolation and deconvolution methods of airways in 3-D CT images, and significant improvement over the full-width-half-maximum method for measurement of not only location of the luminal and outer edge of the airway wall but airway wall thickness.

In this study, cyclic loading tests were conducted on the precast concrete (PC) wide beam (WB)-column joints. Two beam-column joint specimens were fabricated with the arrangement and anchorage details of the reinforcing bars penetrating the beam and column as variables. Through a cyclic loading test, the lateral load-story drift ratio responses, seismic performance characteristics (e.g., ductility, overstrength factor), energy dissipation, strength and stiffness degradations of each specimen were compared and analyzed based on the various indices and the current structural codes (ACI 318-19 and ACI 374.1-05 report). In addition, the shear lag effect was confirmed through the gauge values of the PC beam, and the differences in seismic performance between the specimens were identified on that basis.
