This dissertation was aimed at finding an implication of selecting and educating the gifted of information science discovering features of gifted learner in the field of math and science and the gifted of information science through comparative analysis of observing evaluation for the gifted of information science. Subjects of the study are foundation course learners of University Science Education Institute for the Gifted in the field of physics, earth science, math, information science. We have compared the features of learners of each field through one-way ANOVA about an observing evaluation for one year. In consequence, information science learners showed mostly different features from physics and earth science learners in details of an attitude area and a problem solving area. On this, the researcher concluded that there must be features of the gifted on information science and their difference from gifted learners in math and science was caused by learner levels and features of each field. Based on the result of this study, we expect that we can imply it to selecting and educating the gifted of information science.

When strong static magnetic field is applied to the TMP, it is expected that the presence of the magnetic field might retard the velocity of the blades which results in the change of the pumping speed of the TMP. However, such effect of the magnetic field on the TMP has not been well characterized. Thus, under the strong magnetic field, monitoring pumping speed as well as generated heat, pressure, and vibration of the TMP may be an important issue to understand the magnetic field tolerance of the TMP and the development of magnetic shielding technique for the key components of the pump. For this purpose, magnetic field generation system to the vertical direction by a circular current source was firstly designed and suggested [K. Baik et al., 44th Annual Conf. KVS, 22(1), 153, (2012)]. In the current study, another magnetic field generation systems are presented to apply the magnetic field to the horizontal and radial directions by the rectangular current sources and the permanent magnets respectively. Such systems were made to generate at least 50 Gauss of magnetic field along the vertical direction and at least 25 Gauss of magnetic field along the horizontal or radial direction. Current study introduces the evaluation system of the magnetic field along the vertical, horizontal, and radial directions and presents the measured experimental results of the magnetic field when such systems are combined with the equipment where TMP will be installed.

국내의 강교 도장 시방에 등재되어 있는 도장계에 대한 공용수명 예측을 위하여 현장 열화도 평가 및 촉진 내후성 시험을 수행하였고, 평가 결과에 대한 회귀분석을 통하여 열화모델을 도출하였다. 현장 적용 실적이 없는 도장계에 대해서는 국외 연구 결과 및 본 연구에서 수행한 촉진 내후성 시험 결과를 참고하여 염화고무계 및 우레탄 마감 도장계의 현장 열화도 평가 결과에 열화도 항목별 조정계수를 적용하여 가상의 평가 결과를 도출한 후에 회귀분석을 실시하였다. 공용수명 예측 결과는 금속용사를 적용하면 도장계의 수명을 일반 도장계 대비 2배 이상 연장시킬 수 있다는 것을 보여주었다.

기록관리 기관평가는 실제 기록관리를 하는 현장의 상황조건과 실현 가능성을 반영해야 한다. 기관평가 제도와 지표는 기록관리를 잘 하기 위한 도구이지만 기관의 자원과 노력으로 수행이 어렵다면 현실성이 없다. 2016년 3월 국가기록원이 발표한 2017년 평가제도와 지표는 일선기관에서 1년동안 1명의 기록물관리전문요원이 수행하기 매우 어려울 것으로 예상된다. 전체직원 10% 이상 3회 교육, 전체학교 문서고 사진 제출, 모든 문서의 색인목록 제출, 전자문서 이관이 몇 년 동안 안되는 표준기록관리시스템의 활용도 높이기, 모든 기관의 비전자기록물 이관, 비공개기록물 재분류 실시 등 현장에서 실현하기 힘들고 실제 효과가 있을지 의문스러운 지표들로 구성되어 있다. 국가기록원이 운영하는 기록관리 평가제도와 2017년 지표의 근본적인 문제점을 인정하고, 수년간 일선현장의 경험을 반영하여 더 나은 기록관리를 위한 지혜를 모을 때다.

In this paper, we address the problem of closely spaced source localization using sensor array processing. In particular, the performance efficiency (measured in terms of the root mean square error) of the unconditional maximum likelihood (UML) algorithm for estimating the direction of arrival (DOA) of near-field sources is evaluated. Four parameters are considered in this evaluation: angular separation among sources, signal-to-noise ratio (SNR), number of snapshots, and number of sources (multiple sources). Simulations are conducted to illustrate the UML performance to compute the DOA of sources in the near-field. Finally, results are also presented that compare the performance of the UML DOA estimator with the existing multiple signal classification approach. The results show the capability of the UML estimator for estimating the DOA when the angular separation is taken into account as a critical parameter. These results are consistent in both low SNR and multiple-source scenarios.

This paper shows field test and evaluation results for a wireless vehicle detector with anisotropic magneto-resistive (AMR) sensors. The detector consists of two AMR sensors and mechanical and electronic apparatuses. The AMR sensor senses disturbance of the earth magnetic field caused by a vehicle moving over the sensor and then produces an output indicative of the moving vehicle. In this paper, vehicle speeds are calculated by using two AMR sensors fixed on a board, with constant distance. To test and evaluate the accuracy of the detector in real traffic situations, the detector was installed on a local highway and vehicle speeds and volumes were measured both in a free running and a highly congested traffic. The measurements from the detector are compared with the reference measurements obtained from a traffic camera with the Mean Absolute Percentage Errors (MAPE), which has proved the usefulness of the detector in the field.

School Math Field Trips(SMFT) for School Mathematics can be defined as teaching and learning activity of mathematics going into the field of Korean history, culture, science and technology. This is a literature analysis study to systemize teaching and learning method of mathematics based on literature analysis and real SMFT activity. First, SMFT was introduced to improve cognitive affective and cultural-mathematical teaching and learning method of mathematics. Second, SMFT has three purposes of cognitive, affective and cultural-mathematical. Third, to conduct mathematical education activity the direction of teaching was set. Forth, the progressing way of developing material and SMFT was researched. Fifth, developing the evaluation standard of SMFT and evaluation method was suggested.
