The purpose of this paper is an analysis of the difference between convergence majors and single majors in the convergence core competency and educational performance. We used survey data for the analysis of the convergence core competencies, the results of the midterm and final exams for the education performance. Analysis targets are 10 students in big data business intelligence at Seokyeong University as convergence majors and 11 students in business administration as single majors. The target course was an analysis of economic data provided in the second semester of 2019. And the lecture contents were analysis of big data using R programming. The survey was conducted on December 5, 2019. The convergence core competences were creative thinking, critical thinking, understanding convergence knowledge, problem solving ability, communication skills, cooperation ability, use of convergence tools, consideration, and responsibility. As results of homogeneity tests, we found that there was no significant difference in all competencies, but there were very significant differences in the educational performance evaluated by the midterm and final exams. Therefore we can see willingness to convergence of single majors was no different from that of convergence majors, but had not led to practice. It is desirable to activate and support convergence courses.

In this paper, we propose useful load flow algorithms called FEDL (fast enhanced decoupled load flow). The proposed load flow method can improve the convergence characteristics particularly when the P-Q coupling becomes significant and the power system operating states deviate from the conditions required for stable convergence of the FDL by reflecting in part the effects of the off-diagonal terms in the Jacobian. In our test with IEEE AEP-30 bus system and RTS-96 73-bus system, it converge even when the fast decoupled load flow (FDL) and its variations keeping load flow matrices constant experience convergence problems. Test results show promising performances of the proposed algorithms in their convergence characteristics both in number of iterations and overall convergence speeds.

A top emission organic light emitting diode comprising of a triple anode on polycarbonate $film/TNATA/NPB/Alq_3:C545T/cathodes$ has been fabricated. The triple layer structure of Cr/Al/Cr allowed for fabrication of a crack-free anode and provided better higher work function than ITO anode.The anode showed compatibility with flexible plastic substrate and no crack was formed during bending test while ITO anode showed crack.

Objectives: This was carried out to develop an integrated care convergence curriculum. Methods: An online survey was conducted on 312 public health college students, and frequency analysis, t-test, ANOVA, and chi-square test were conducted. Results: Awareness of convergence education (2.55) and experience of convergence education (10.3%) were low, but those with education experience had high awareness of integrated care and convergence education (p<0.001). The need for education (3.07) and manpower training (3.14) were both high, and the preferred training content was first aid (3.57). Conclusions: Additional research is needed on the development of integrated care convergence curriculum.

본 연구목적은 어깨재활운동 융합프로그램의 효과를 확인하기 위함이다. 비동등성 대조군 전후설계에 따라 어깨수술환자 58명을 연구대상으로 하였다. 실험군에게는 동영상교육, 어깨재활운동 및 운동모니터링으로 구성한 어깨재활운동 융합프로그램을 적용하였다. 자료는 구조화된 질문지와 어깨관절운동범위를 측정하여 수집하였으며 기술통계, ${\chi}^2-test$, t-test 및 ANCOVA로 분석하였다. 연구결과 실험군의 어깨통증은 대조군보다 유의하게 낮았으며(p<.001), 어깨관절운동범위와 운동자기효능감은 대조군보다 유의하게 높았다(p=.038; p<.001). 그러므로 어깨재활운동 융합프로그램은 어깨수술환자를 위한 효과적인 재활중재로 활용될 수 있으며 다양한 임상실무영역에서 지속적인 융합중재개발의 확장이 요구된다.

본 연구의 목적은 미혼여성의 자궁경부암 예방활동에 따른 자궁경부암 지식과 자궁경부암 예방행위 의도를 융합적으로 파악하기 위함이다. 216명의 여성을 대상으로 자가보고 설문지를 통해 수집한 자료는 SPSS 프로그램을 사용하여 분석하였다. 연구 결과, 미혼여성의 33.9%가 HPV 예방접종을 시행하였고 7.9%가 Pap test를 시행하였다. Pap test와 HPV 예방접종을 모두 시행한 그룹은 6.7%, Pap test 또는 HPV 예방접종을 시행한 그룹은 28.5%이었다. 자궁경부암 예방활동에 따라 자궁경부암 가족력, 자궁경부암 예방행위에 대한 주관적 규범, 지각된 행위통제, 행위의도의 차이가 있었다. 따라서 미혼 여성의 자궁경부암 예방활동에 대한 감수성을 높이는 것이 중요하며, 미혼 여성의 자궁경부암 예방을 위해 건강 전문가가 가장 의미 있는 지원시스템을 수행하는 것이 중요하다. 또한 미혼 여성이 자궁경부암 예방에 보다 적극적으로 참여할 수 있도록 다양한 정책을 적극적으로 홍보하고 지원해야 한다.

A new miniaturized 4-port waveguide generating a transverse electromagnetic wave is proposed. The waveguide presents enhanced performance of higher field uniformity in extended test volume up to an increased test frequency limit compared to that of the conventional 2-port waveguide. The advantageous features of the proposed waveguide have been obtained through a new design scheme based on effective miniaturization maintaining good impedance matching. Consequently, we can provide a more accurate electromagnetic compatibility test method, covering larger devices operating in higher frequencies, which is a marked improvement upon the conventional approaches.

This study presents the development of a lifetime test bench for the strain wave reducer which is a precision gear reducer of the robot to realize fault diagnosis and failure prognostics. To this end, the lifetime test bench was designed to detect the vertical forward/reverse direction rotation load. Through the lifetime test bench, it is possible to apply the same load spectrum from robot working scenarios. We developed a data integration gateway for fault data collection. Through the development of dedicated software for fault diagnosis and failure prognostics, these data from vibration, noise and temperature sensors were collected and analyzed along with the operation of the lifetime evaluation.

Since income growth rate and poverty level are related, there is a possibility that the poverty rate may converge in the long run steady state as well. If the poverty rate converges, then for this study the state that begins with the high poverty rate would have a higher poverty reduction rate. To examine the convergence of poverty rate among the US states, this study uses two times series methodologies. First, in order to prevent the power loss from ignoring the structural break when testing for a unit root in a single time series, this study employs the newly developed panel LM unit root tests with level and trend shifts. The results of unit root tests of the log of poverty rate without allowing for structural breaks show that twenty six states reject the null hypothesis of unit root test for the ADF test, twenty five states for the LM test, and thirty five states for the RALS-LM test. The result of unit root tests that allow one structural break shows that the null hypothesis of a unit root test is rejected for twenty two states with the LM test, and thirty three states with the RALS-LM test. This supports poverty rates are converging among US states.
