좋은 수업은 수업을 구성하는 요소들이 하나의 체제로서 유기적 연관성을 갖는다. 평가 준거에 대한 충분한 설명이나 합의 없는 일방적 평가, 평가과정의 신뢰성을 담보할 수 없는 주관적 평가 그리고 학습 과정과 분리된 탈 맥락화된 평가는 좋은 수업이나 건강한 학습생태계를 위협하는 요소가 될 수 있다. 이 연구는 교육 평가와 관련된 문제를 해결하기 위해 루브릭(rubric)을 통한 평가와 그 효과를 분석하였다. '루브릭'은 수업목표를 토대로 수행과제를 평가하는 준거와 수행의 질을 여러 단계로 상세히 묘사한 서술적 평가도구다. 영화 리터러시 평가를 위해 적용한 루브릭은 '분석적 루브릭'으로서 영화 이해 리터러시, 영화 제작 리터러시, 그리고 영화 활용 리터러시를 포괄한다. 루브릭에 대해 학습자들은 타당하고 매우 유용한 학습 성찰 도구로 인식하였다.

In this study, long-term measurement data were applied to the LOADEST model and used as an analysis tool to identify and interpret trends in pollution load. The LOADEST model is a regression equation-based pollution load estimation program developed by the United States Geological Survey (USGS) to estimate the change in the pollution load of rivers according to flow rate and time and provides 11 regression equations for pollution load evaluation. As a result of simulating the Gwangjuchen2, Pungyeongjeongchen, and Pyeongdongchen in the Yeongbon B unit basin in the middle and upper reaches of the Yeongsan River with the LOADEST model using water quality and flow measurement data, lower values were observed for the Gwangjuchen2 and Pyeongdongchen, whereas the Pungyeongjeongchen had higher values. This was judged to be due to the characteristics of the LOADEST model related to data continuity. According to the parameters estimated by the LOADEST model, pollutant trends were affected by increases in the flow. In addition, variability increased with time, and BOD and T-P were affected by the season. Thus, the LOADEST model can contribute to water quality management as an analytical tool for long-term data monitoring.

빅데이터 분석은 데이터 저장소에 저장된 대용량 데이터 속에서 의미 있는 새로운 상관관계, 패턴, 추세를 발견하여 새로운 가치를 창출하는 과정이다. 또한 대부분의 빅데이터 분석 기술 방법들은 기존 통계학과 전산학에서 사용되던 데이터 마이닝, 기계 학습, 자연 언어 처리, 패턴 인식 등이 이에 해당된다. 그리고 빅데이터 분석 도구인 R언어를 이용하여 전-처리된 텍스트 데이터를 이용하여 다양한 시각화 함수를 통해 분석결과를 표현할 수 있다. 본 연구에서 사용된 데이터는 한국정보통신학회 학회지 논문 중에서 2021년 3월호 논문 21편을 대상으로 분석을 하였다. 최종 분석결과는 가장 많이 언급된 키워드는 "데이터"가 305회로 1위를 차지하였다. 따라서 이러한 분석결과를 바탕으로 연구의 한계와 이론적 실무적 시사점을 제시하고자 한다.

A rotordynamic system consists of components that undergo rotational motion. These components include shafts, impellers, thrust collars, and components that support rotation, such as bearings and seals. The motion of this type of rotating system can be modeled as two-dimensional motion and, accordingly, the equation of motion for the rotordynamic system can be represented using complex coordinates. The directional frequency response function (dFRF) can be derived from this complex coordinate system and used as an effective analytical tool for rotating machinery. However, the dFRF is not widely used in the field because most previous studies and commercial software are based on real coordinate systems. The objective of the current study is to introduce the dFRF and show that it can be an effective tool in rotordynamic analysis. In this study, the normal frequency response function (nFRF) and dFRF are compared under rotordynamic analysis for isotropic and unisotropic rotors. Results show that in the nFRF, the magnitude of the response is the same for both positive and negative frequencies, and the response is similar under all modes. Consequently, the severity of the mode cannot be identified. However, in the dFRF, the forward and backward modes are clearly distinguishable in the frequency domain of the isotropic rotor, and the severity of the mode can be identified for the unisotropic rotor.

크리스챤 영성의 관점에서는 '영성(靈性)'이란 바로 우리가 우리 자신이 되게 하는 영적 씨앗으로써 누구나 그 씨앗을 발아시켜 자기 자신의 온전한 본 모습을 찾아가는 길이다. 자기실현(自己實現) 또는 개성화과정은 융의 중심사상으로, 개인적 성격의 발달을 지향하는 분화의 과정이다. 달리 말해 의식과 무의식의 통합을 이루어 자신이 가지고 있는 모든 기능을 온전히 제대로 사용할 수 있도록 함으로써 전체성(全體性)을 달성해 나가는 과정이다. 그렇다면 이는 인간 누구에게나 주어진 삶의 중심과제일 수밖에 없다. 이런 측면에서 보면, 영성신학적인 견해와 분석심리학적인 견해가 서로 만날 수 있는 길이 보인다. 스위스 취리히(Zurich)의 연방기술연구소에서 1938년부터 1941년까지 열렸던 특강 시리즈에서, 융은 동양과 서양의 전형적인 상징과 변환과정에 대한 고찰을 통해 요가와 이냐시오 성인의 '영신수련', 그리고 연금술에 대해 강의하면서, 서양을 대표하는 인간 정신의 변환의 도구로써 이냐시오의 '영신수련'을 들고 있다. 따라서 본 논문에서는 이냐시오의 '영신수련'에 대한 융의 견해를 중심으로 '영신수련'을 개성화의 과정과 비교해봄으로써 그 분석심리학적 함의를 조명해보는데 중점을 두었다.

최근 기업들이 고객관계관리(CRM)의 도입과 확산에 많은 노력을 기울이고 있는 가운데, 정보통신기술의 발달과 인터넷 사용의 활성화로 인하여 온라인 채널을 활용하여 CRM을 구현하는 이른바 e-CRM에 대한 기업들의 관심 역시 높아지고 있다. 지금까지 많은 연구자들이 CRM의 성공요인들을 식별하고, 각 요인들의 우선순위를 알아보고자 노력을 기울여 왔다. 하지만, e-CRM 분야에 대한 성공요인 관련 연구는 지금까지 충분히 이루어지지 못했다. 이에 본 연구에서는 기업들이 성공적으로 e-CRM을 구현을 위한 준비를 할 수 있는 가이드라인을 제시하기 위해, 기존에 연구되었던 다양한 e-CRM구축의 성공요인들을 도출, 정리하고, 각 요인별 상대적 중요도를 전문가 설문을 통해 분석하여, 우선순위를 살펴보고자 하였다. 이 때 요인별 상대적 중요도는 전통적으로 많이 활용되고 검증되어 온 분석적 계층 프로세스(AHP) 기법을 이용하여 도출하였다. 기존의 연구들은 대부분 조직적인 요소와 기술적인 요소들로 성공요인을 분석하였지만 본 연구에서는 e-CRM의 기능적인 관점으로 성공요인을 도출하고자 하였다. 분석 결과, e-CRM의 성공을 위해서는 분석-운영-협업 CRM의 세 부분이 모두 균형 있게 관리되어야 하며, 특히 최고경영자의 전폭적인 지원과 양질의 고객정보 확보, 그리고 고객의 요구사항에 효과적으로 반응하는 우수한 온라인 처리능력의 확보가 중요한 것으로 나타났다.

Purpose Serum Thyroglobulin measurement is a major tool for the follow-up of differentiated thyroid cancer (DTC) patients. Thyroglobulin is Normal thyroid tissue, or thyroid cancer tissue produced only. Thyroid hormone to a halt without Tg differentiation of thyroid cancer recurrence just by measuring how to decide whether there was increasing expectations if I can do it instead. Therefore, in excellent sensitivity Tg new inspection of the functional sensitivity by measuring the looked to evaluate the usefulness of reagents. Thyroidectomy is measuring the numbers Tg (total thyroidectomy) remaining thyroid ablation and radioactive iodine (radioactive iodine remnant ablation, RRA) DTC in patients being diagnosed with or help predict the remaining early detection of thyroid cancer recurrence. Materials and Methods Agent that I'm currently using Tg of the measurements of low clinical specimen for a second drainage of the three (0.08 0.17, 0.98, ng/mL) within the scope of the dilute magnification (2, 4, 8, 16, 32 times) by dilute Intraassy (n=10) and Interassay (n=10) out in no time. Concentration value according to the coefficient of variation and the mean and standard deviation of each measurement (Coefficient of variation, CV) the absolute value of the measured values that corresponds to 20 percent target a coefficient of variation of CV Find the value of the concentration of the functional sensitivity measurement did. Also, analytical sensitivity with recovery rates, Dilution test inspections, and interrelationship, compared. Results Sensitivity is an excellent analytical sensitivity within the prosecutor kit Tg 0.006 ng/mL, and core analytical sensitivity, conducted by the 0.006 ng/mL to same conclusion. Be rather high to 142 percent recovery rate was 60 to measurement and functional sensitivity, 0.01766 ng/mL(Intraassay n=10) was measured at. CBC is relatively good correlation as ($R^2=0.949$) the correlation. Conclusion Recently ultrasensitive thyroglobulin this clinically important indicators of the previous kit and demands are lower than sensitivity to the measurement results. Therefore, ultrasensitive thyroglobulin test is correlated that there would be useful in value in nuclear medicine the thyroid gland.
