Geo-based application services linked with the Open Geospatial Consortium (OGC) Web Processing Service (WPS) protocol have been regarded as an important standardized framework for of digital earth building in the web environments. The WPS protocol provides interface standards for analysis functionalities within geo-spatial processing in web-based service systems. Despite its significance, there is few performance tests of WPS applications. The main motivation in this study is to perform the comparative performance test on WPS standards. Test system, which was composed of WPS servers, WPS framework, data management module, geo-based data processing module and client-sided system, was implemented by fully open source stack. In this system, two kinds of geo-based image processing functions such as cloud detection and gradient magnitude computation were applied. The performance test of different server environments of non-WPS, synchronous WPS 1.0 and asynchronous WPS 2.0 was carried out using 100 threads and 400 threads corresponds client users on a web-based application service. As the result, at 100 threads, performance of three environments was within an adjacent range in the average response time to complete the processing of each thread. At 400 threads, the application case of WPS 2.0 showed the distinguished characteristics for higher performance in the response time than the small threads cases. It is thought that WPS 2.0 contributes to settlement of without performance problems such as time delay or thread accumulation.

The government is encouraging the notice of obligatory reclaimed asphalt as a result of the economic and social positioning of green growth to reduce the amount of waste resources and to solve natural resource problems by recycling continuously generated waste resources. However, it is necessary to develop application guideline for each application to apply reclaimed asphalt to the site because quality control of the reclaimed asphalt is difficult and the specifications are ambiguous as well. Therefore, in this study, the mix design, quality test, performance test, and finite element analysis about reclaimed Asphalt Pavement were conducted to develop application guideline for reclaimed hot asphalt. The mix design was carried out for the comparative general hot mix asphalt mixture, the reclaimed hot mix asphalt mixture using the additive, and the reclaimed hot mix asphalt mixture without the additive. Indirect tensile strength and tensile strength ratio tests were used to characterize the reclaimed hot mix asphalt mixture. Using the results of dynamic modulus test and FWD test for KPRP analysis and finite element analysis, the performance life was evaluated for general pavement and pavement using recycled aggregate. Finally, the life cycle cost analysis was used to compare and analyze the economics of reclaimed asphalt concrete pavement.

The practical application of REBCO coated conductor (CC) tapes, vital for energy transmission (e.g., cable application) and high-field magnets (e.g., coil application), necessitates efficient and simple quality assessment procedures. This study introduces a systematic approach to assess the electromechanical properties of REBCO CC tapes under 77 K and self-field conditions. The approach involves customized tensile and bending tests that clarify the critical current (I_c) response of the CC tapes under mechanical loads induced by tension and bending. This study measures the retained Ic values of commercially available GdBCO CC tapes under 250 MPa tensile stress and 40 mm bending diameter. Through experimentation, the study demonstrates the resilience of these tapes and their suitability for applications. By presenting a simplified stress-based analysis and a bending test of the tapes, the study contributes to effective quality assessment methods for the development of practical superconducting products.

Purpose: Although microwave diathermy is widely employed, research conducted in South Korea indicates a lack of theoretical understanding concerning the appropriate application intensity. Consequently, there is a need to enhance the objectivity of microwave diathermy by conducting quantitative studies to determine its effective application intensity and provide suitable application parameters. Methods: The study was performed on 60 participants, divided equally into 40W or 80W microwave diathermy intervention groups. Microwave diathermy was applied at 2,450MHz to iliocostalis and longissimus muscles for 15 minutes in each group. Ranges of motion were compared before and after intervention using straight leg raise (SLR) test results. The analysis was performed using the paired t-test and the independent t-test. Results: SLR angles increased significantly in both groups after intervention, but the 80W group exhibited a greater post-intervention angle increase. While no significant intergroup difference was observed between pre-intervention angles, post-intervention angles were significantly different. Conclusion: The study confirms that microwave diathermy treatment at 40W for 15 minutes effectively increases SLR angles but that treatment at 80W has a greater effect. Further research is warranted to establish quantitatively the optimal time and intensity settings for microwave diathermy.

인쇄 회로 보드 수준의 테스팅을 위해 제안된 IEEE 표준 1149.1은 보드상의 테스트 지점에 대한 제어용이도와 관측용이도를 향상시켜 보드의 테스트를 용이하게 해준다. 그러나, 경계 주사 환경에서는 테스트 입력과 테스트 결과에 따른 데이터가 하나의 주사 연결에 의해서 직렬로 이동된다. 이는 테스트 적용시간을 증가시키고 따라서 테스트에 드는 비용을 증가시킨다. 테스트에 소모되는 시간을 줄이기 위해 병렬로 다중주사 경로를 구성하는 방법이 제안되었다. 하지만 이는 여분의 입출력 핀과 내선을 필요로 한다. 더구나 IEEE 표준 1149.1은 주사 경로 상에 있는 IC들의 병렬 동작을 지원하지 않기 때문에 표준에 맞게 설계하기가 어렵다. 본 논문에서는 하나의 테스트 버스로 두 개의 주사 경로를 동시에 제안하는 다중 주사 경로 접근 알고리즘에 기초하여 적은 면적 오버헤드를 가지고 빠른 시간 내에 보드를 테스트할 수 있는 새로운 보드수준의 내장된 자체 테스트 구조를 구현하였다. 제안된 내장된 자체 테스트 구조는 두 개의 주사 경로에 대한 테스트 입력과 테스트 결과를 이동시킬 수 있으므로 테스트에 소모되는 시간을 줄일 수 있고 또한 테스트 입력의 생성과 테스트 결과의 분석에 소모되는 비용을 줄일 수 있다.
