본 연구는 빅데이터를 분석하여 ‘영유아교사 교권침해’에 대한 사회적 인식을 살펴봄으로써 우리 사회가 이를 어떻게 바라보고 이해하는지를 파악하는 데 그 목적이 있다. 이에 「아동복지법」개정 및 삭제 이슈를 계기로 정부가 「아동복지법」개정 의사를 밝힌 2021년 12월 21일부터 2023년 12월 20일까지 ‘영유아교사+교권+침해’ 검색어를 중심으로 국내 온라인 텍스트 데이터 키워드를 TF-IDF, 중심성 및 CONCOR 분석하였다. 먼저 TF-IDF 분석 결과, ‘아동’, ‘학부모’, ‘영유아교사’, ‘보호’, ‘교육’ 등 주제와 관련된 인물 · 장소가 높은 빈도를 차지했다. 이는 연결 · 근접 · 매개중심성 분석에서도 높게 나타났다. 마지막으로 CONCOR 분석 결과, ‘교권침해가 사회적으로 주목받게 된 사건 및 그 여파’, ‘공식적 지지체계’, ‘교육적 상황에서 침해된 교권’, ‘교사의 인권 보장 요구’, ‘생활지도 측면에서의 교권침해 법안 논의’, ‘악성 민원 및 아동학대 신고에 의한 교권 상실’, ‘비공식적 지지체계’, ‘어린이집 교사의 권리’ 즉 8개의 군집이 제시되었다. 본 연구를 통해 교권회복의 필요성을 인식하는 대중, 교권침해와 아동의 보호권 행사 간의 관계, 학부모와 교사의 동등한 협력관계 개선 등 교권침해 논란의 현주소를 구조적으로 파악할 수 있었다. This study aims to understand how our society perceives ‘infringement of teaching rights of early childhood teachers’ by analyzing big data. For this purpose, raw data was collected with ‘early childhood educator+rights+violation’ keywords based on the big data provided by TEXTOM. The TF-IDF, Centrality, and CONCOR analyses were conducted from December 21, 2021 to December 20, 2023. The results were as follows. First, the TF-IDF analysis highlighted that terms related to ‘child’, ‘parent’, ‘early childhood educator’, ‘protection’, and ‘education’ were frequently mentioned, indicating their significant relevance to the topic. This was further confirmed by Centrality analysis, showcasing the importance of these terms in the discourse. Second, the CONCOR analysis revealed eight clusters: ‘events and their aftermath drawing social attention to rights violations’, ‘formal support systems’, ‘rights violations within educational settings’, ‘demands for the protection of teachers’ rights’, ‘discussions on behavior management legislation’, ‘the link between the undermining of teachers’ rights and child abuse reports’, ‘informal support systems’, and ‘the rights of daycare center teachers’. This study is meaningful in that it revealed the public recognition of the need to restore teaching authority, the relationship between infringement of teaching authority and the right to protect children, as well as the need to improve the equal partnership between parents and teachers.

The NASA Antarctica balloon experiment CREAM has successfully collected the data of energetic cosmic rays during six flights in past years. It recently observed the unexpected discrete hardening in energy spectra of comic rays. However high-statistics data of energetic cosmic rays are required for the further investigation of the unexpected hardening in comic-ray energy spectra. The International Space Station (ISS) is an ideal platform for the CREAM experiment to investigate the unexpected hardening and explore the fundamental issues like the acceleration mechanism and the origin of energetic cosmic rays because of the high duty cycle of the experiment in the ISS platform. We will present the design of the ISS-CREAM experiment, and the development and fabrication status of the detector components including the 4-layer silicon charge detector which will measure the charge constitution of cosmic rays with unprecedented accuracy.

We report technique used for improved measurement uncertainties for Photon detection efficiency(PDE) of $1mm^2$ single pixel SiPM. It consists of 470nm LED light source, two 2-inch integrating sphere and two NIST calibrated silicon photodiodes that have ${\pm}2.4%$ calibration error. With raytracing simulation of our experimental setup, we predict number of photon into SiPM and measurement uncertainty. For MPPC, Hamamatsu suggested PDE(1600 micro pixel) including crosstalk and afterpulse is 23.5% at 470 nm. By using new low calibration error photodiode and raytracing simulation, our simulation result has ${\pm}3%$ measurement uncertainty. The technical detail of measurement, simulation are presented with the results and implication.

The development of electric circuit fabrication on heat and chemically sensitive polymer substrates has attracted significant interest as a pathway to low-cost or large-area electronics. Flexible electronics are the electronics on flexible substrates such as a plastic, fabric or paper, so that they can be folded or attached on any curved surfaces. They are currently recognized as one of the most innovating future technologies especially in the area of portable electronics. The conventional vacuum deposition and photolithographic patterning methods are well developed for inorganic microelectronics. However, flexible polymer substrates are generally chemically incompatible with resists, etchants and developers and high temperature processes used in conventional integrated circuit processing. Additionally, conventional processes are time consuming, very expensive and not environmentally friendly. Therefore, there are strong needs for new materials and a novel processing scheme to realize flexible electronics. This paper introduces current research trends for flexible electronics based on (a) nanoparticles, and (b) novel processing schemes: nanomaterial based direct laser patterning methods to remove any conventional vacuum deposition and photolithography processes. Among the several unique nanomaterial characteristics, dramatic melting temperature depression (Tm, 3㎚ particle~150℃) and strong light absorption can be exploited to reduce the processing temperature and to enhance the resolution. This opens a possibility of developing a cost effective, low temperature, high resolution and environmentally friendly approach in the high performance flexible electronics fabrication area.
