다양한 학문을 넘나들며 새로운 지식과 관점을 창의적으로 추구하는 역량은 21세기 융복합시대를 살아가기 위한 기초적 소양으로 자리매김하고 있다. 다양한 창의교육 프로그램 개발에 따라 학습자의 학업성취도를 객관적이고 체계적으로 평가할 수 있는 평가도구 또한 요구되고 있다. 이에, 본 논문에서는 초·중등학생 대상 창의 융합 교육 프로그램의 평가도구로 하이퍼 블렌디드 실천모델에 기반하여 자기 평가, 동료 평가, 창의성 평가, 자기 성찰도구를 제안하였다. 개발된 평가도구는 타당도 검사를 통해 2개 문항을 수정하고 4개 문항을 삭제하여 보다 완성된 평가도구의 개발을 꾀했다. 또한, 평가도구는 전국 초·중등학생 596명을 대상으로 적용되었으며, 적용 결과는 일원배치 분산분석과 워드클라우드를 통해 분석되었다. 분석 결과, 자기 평가와 자기 성찰도구는 학년군에 따른 문항 개발이 필요할 것으로 나타났다. 더불어, 변화하는 교실 환경 속 원격 수업이나 여러 교육 활동에서 본 평가도구를 활용하기를 제안한다. 본 논문을 통해 창의 융복합 교육을 위한 평가체계 및 도구 개발에 시사점을 제공하기 바란다.

2015 개정 교육과정이 도입됨에 따라 초등학교에서도 소프트웨어 교육이 의무화되었다. 실과 교과의 한 단원으로 구성되는 소프트웨어 교육의 내용은, 정보 윤리, 알고리즘과 프로그래밍, 컴퓨터과학의 원리로 이루어져 있는데 교수 학습 방법으로 놀이 중심의 언플러그드 활동을 권장하고 있다. 하지만 현장 교사들은 적합한 언플러그드 활동 자료의 부재를 가장 큰 어려움으로 생각하고 있었으며, 기존 자료가 성취기준 달성에 적합하지 않다는 점, 단순한 놀이 교육이 많아 컴퓨팅 활동과 연계되지 않는 점 등을 해결해야 할 문제로 지적하였다. 이에 본 연구에서는 초등 소프트웨어 교육의 성취기준으로 제시된 기본 제어구조는 물론 센서를 활용한 다양한 활동을 통해 창의적 문제해결력을 키울 수 있는 언플러그드 활동 중심의 로봇을 개발하였고 이를 활용한 소프트웨어 수업을 통해 효과성을 검증하였다.

IMU(Inertial Measurement Unit) 센서의 가속도와 각속도를 이용하여 거리측정을 하고 측정값을 이용하여 사용자가 원하는 실내공간에 적용하여 사용자 혹은 디바이스가 실내공간을 인식하는 교육용 장비를 소개한다. 본 교육장비를 이용해서 다양한 위치 인식 및 추적 알고리즘을 학습할 수 있고 창의적 공학설계 작품을 구현할 수 있다. IMU 센서의 데이터 값을 $I^2C$(Inter-Integrated Circuit)을 통해 MCU(microcontroller unit)에 전송하고 필터와 연산방식을 통해 데이터 값을 처리 후 실내 위치 인식 알고리즘을 통해 위치인식을 한다. 그리고 무선통신을 이용하여 처리된 값을 송수신하여 사용자가 인식하도록 설계한다. 본 교육 장비를 이용하여 "IMU센서를 이용하여 이동거리를 산출과 데이터 값을 이용한 가상공간 구현 및 인식"의 사례를 소개하고 그 설계를 기반하여 다양한 창의적 공학설계 적용에 대해서 논한다.

The aims of this study are to develop a STEAM program focused on the appearances of birds' beaks and insectivorous plants and to identify its influence on elementary students' basic scientific process skills, creative problem solving ability and affective domain. For these objectives, the STEAM program was developed by reorganizing contents of the appearances of animals and plants in the units of 'Life of Animals' and 'Life of Plants' from 2009 revised national science curriculum for 3th and 4th grades. The developed STEAM program was applied to twenty nine 3th grade students of J elementary school located in S city. As a result of applying the STEAM program, the experimental group in this study showed significant improvements of the creative problem solving ability, scientific process skills and affective domain compared to the control group's scores. Therefore, development studies on STEAM programs integrated different science fields using animals and plants could be meaningful works to encourage elementary students' skills and interest.

A large number of tasks being executed by individuals now are in a central requirement of the creative solutions consolidated with associates' multiple skills, knowledge bases and efforts who are capable of entertaining various viewpoints. Followed by such a variation, teams or groups were gradually settled in a major form of the enterprise's creative revelations. However, in spite of the consistent augmentation of team's application, researches of a group's ability that utilizes individual creative competence effectively are now in the excessively insufficient manner. Accordingly, this research is to verify mutual relationship between individual creativity and group creativity, and furthermore, to present integrative capability and knowledge sharing of the group as a distinctive variable to observe the mechanism of how the individual creativity becomes aggregated with the group creativity through a process. As a result, the relationship between the individual creativity and the group creativity was so significant that it showed that the integrative capability and knowledge sharing were mediated in the connection of the two variables. This research contributes to the comprehension of the relationship between individual and group creativity through the role of a group's integrative capability and knowledge sharing. In addition, further research direction with in-depth idea is presented to develop research on creativeness from the practical standpoint implicated in this research.

Ginseng (Panax ginseng Meyer) has been used as traditional herbal drug in Asian countries. Ginsenosides are major components having pharmacological and biological efficacy like anti-inflammatory, anti-diabetic and anti-tumor effects. To control the quality of the components in diverse ginseng products, we developed a new quantitative method using LC-MS/MS for 13 ginsenosides; Rb1, Rb2, Rc, Rd, Re, Rf, 20(S)-Rh1, 20(S)-Rh2, Rg1, 20(S)-Rg3, F1, F2, and compound K. This method was successfully validated for linearity, precision, and accuracy. This quantification method applied in four representative ginseng products; fresh ginseng powder, white ginseng powder, red ginseng extract powder, and red ginseng extract. Here the amounts of the 13 ginsenosides in the various type of ginseng samples could be analyzed simultaneously and expected to be suitable for quality control of ginseng products.

We investigated light extraction film based on polymer dispersed liquid crystal (PDLC) for application in organic light emitting diodes (OLEDs). At least 30 seconds of direct UV irradiation process for curing PDLC film on a bottom-emitting OLEDs was successfully achieved without damage on the intrinsic properties of the OLED. We demonstrated that high haze and transmittance can be tuned simultaneously by controlling the UV curing time. By adding PDLC as an external layer without any additional treatment, the light scattering and extraction is increased. Consequently, a PDLC scattering film with 89.8% and 59.9 of total transmittance and haze respectively, achieved about 16% of light intensity enhancement from integrating sphere measurement.

Three-dimensional (3D) selfie services, one of the major 3D printing services, print 3D models of an individual's face via scanning. However, most of these services require expensive full-color supporting 3D printers. The high cost of such printers poses a challenge in launching a variety of 3D printing application services. This paper presents a stencil-based 3D facial relief creation method employing a low-cost RGBD sensor and a 3D printer. Stencil-based 3D facial relief is an artwork in which some parts are holes, similar to that in a stencil, and other parts stand out, as in a relief. The proposed method creates a new type of relief by combining the existing stencil techniques and relief techniques. As a result, the 3D printed product resembles a two-colored object rather than a one-colored object even when a monochrome 3D printer is used. Unlike existing personalization-based 3D printing services, the proposed method enables the printing and delivery of products to customers in a short period of time. Experimental results reveal that, compared to existing 3D selfie products printed by monochrome 3D printers, our products have a higher degree of similarity and are more profitable.
