Patient-physician interaction (PPI) is an important area in medical education, but in-depth discussions on the content of the outcome of patient-doctor education are rare. Therefore, in this study, we will systematically analyze the research on PPI education in Korea. In this study, papers searched with keywords related to PPI education from Korea's academic journal service were targeted according to a systematic literature analysis method. The scope of the study was to include papers published in academic journals that are candidates for Korea Citation Index registration, excluding dissertations, research reports, posters, conference presentations, books, and internet materials. The content included papers targeting medical education and medical school students was set as the range. As a result of the analysis, although communication between PPI has many positive effects in the PPI in medical education at medical schools, obstacles do occur, and various ways to overcome them were suggested. Therefore, although medical interview training between patients and doctors in medical schools is necessary, it was analyzed as being based on overseas research or lacking in specific content. The core of PPI education appears to be medical interviews, and it seems necessary to discuss whether empathy or patient-centered medical care are appropriate as the main principles of PPI education in Korea. Therefore, education on the patient-doctor relationship is an important element in medical humanities and medical humanities education, and it is expected that research and education on this will progress more actively.

In order to overcome the heterogeneity of mathematics education in South Korea and North Korea in preparation for the future integration of North and South Korea, research on North Korean mathematics education needs to be studied qualitatively in various aspects and fields. In order to do this, it is necessary first to elaborate and analyze the results of the research on North Korean mathematics education reported so far, to find important implications and find out the research fields that have been neglected in the meantime. Therefore, this study analyzed the trends of previous studies for establishing the direction of future studies on mathematics education in North and South Korea. As a result, it can be seen that the study on North Korean mathematics education in Korea is limited to curriculum analysis, textbook comparison, and comparison of mathematical terms between North and South.

Problem solving in real life is a core competency commonly adopted in several subjects recently. The real-world problems were rarely resolved with only one domain of knowledge. Thus, convergence education is becoming a trend in many countries. As on-line education is revitalized because of COVID-19, the need for changes to STEAM education is emerging. In December 2019, the on-line education systems quickly settled in schools because of COVID-19. During the first semester of 2020, most school education was conducted as virtual/distance learning classes. It is necessary to analyze how much technology has been used in the STEAM classes in Korea. This paper analyzes the research papers related to the STEAM education in Korea conducted in the last 10 years. By doing this, we analyze what kind of edutechs we were interested in, what kind of STEAM education actually occurred, and to whom it was conducted. The previous research papers analyzed in this paper are the papers in the Korea Citation Index accredited journals and candidate journals. Finally, this paper proposes educational changing factors to be considered for future technology-based STEAM education.

A novel pulse fitting analysis (PFA) method is presented for the acquisition of nuclear spectra. The charging process of the feedback capacitor in the resistive feedback charge-sensitive preamplifier is equivalent to the impulsive pulse, and its impulse response function (IRF) can be obtained by non-linear fitting of the falling edge of the nuclear pulse. The integral of the IRF excluding the baseline represents the energy deposition of the particles in the detector. In addition, since the non-linear fitting process in PFA method is difficult to achieve in the conventional architecture of spectroscopy system, a new multi-channel analyzer (MCA) based on Zynq SoC is proposed, which transmits all the data of nuclear pulses from the programmable logic (PL) to the processing system (PS) by high-speed AXI-Stream in order to implement PFA method with precision. The linearity of new MCA has been tested. The spectrum of ¹³⁷Cs was obtained using LaBr₃(Ce) scintillator detector, and was compared with commercial MCA by ORTEC. The results of tests indicate that the MCA based on PFA method has the same performance as the commercial MCA based on pulse height analysis (PHA) method and excellent linearity for γ-rays with different energies, which infers that PFA method is an effective and promising method for the acquisition of spectra. Furthermore, it provides a new solution for nuclear pulse processing algorithms involving regression and iterative processes.

본 연구는 수학교육학의 기초학문이 되는 수학과 다학문적인 성격을 띤 수학교육학을 학문학적으로 비교할 때 수학과 비교되는 수학교육학의 학문적 특징을 형식과학 대비 경험과학에 대한 논의를 중심으로 전개했다. 또한 연구방법을 중심으로 수학교육학의 기반이 되는 교육학, 심리학과 같은 사회과학과 수학교육학의 비교를 통해 수학교육학의 연구 방법적 특징에 대해 문헌연구를 통해 고찰해보았다. 본 연구에 따르면, 수학교육학은 연구 방법적 측면에서 자연과학 이라기보다는 사회과학의 성격을 많이 가지고 있으며, 형식과학으로서의 수학과 그 외 수학교육학의 인접학문들과는 구별되는 독특한 특징을 가지고 있다는 사실을 알 수 있었다. 따라서 각 학문영역 연구의 주장하는 바의 정당성은 전혀 다른 시각으로 이해되어야 한다.
