본 연구의 목적은 만 5세 유아를 대상으로 전래동화에 기초한 장단-말놀이 활동을 개발하고 유아의 언어능력, 국악능력, 그리기표상능력에 미치는 효과를 분석하여 유아교육 현장 적용 및 타당성을 검증하는데 있다. 연구대상은 K시에 소재한 실험집단 C유치원 만 5세 유아 20명과 비교집단 R유치원 만 5세 유아 20명을 연구 대상으로 선정하였으며 연구대상의 평균연령은 실험집단 72.05개월, 비교집단 72.40개월로 동질 집단인 것으로 나타났다. 연구도구는 ‘구문의미 이해력 검사’(서울장애인종합복지관, 2009), 유아국악능력 검사 도구(박형신, 2006), 그리기표상능력(지성애, 2001)을 사용하였다. 연구결과는 SPSS 18.0 프로그램을 사용하여 공변량분석(ANCOVA)를 실시하였다. 본 연구 결과는 ‘전래동화에 기초한 장단-말놀이 활동’은 유아의 언어능력, 국악능력 증진에 효과적인 것으로 밝혀졌다. The purpose of this study is to analyze the effects of a Korean folktale based rhythm-word play activity on children’s language, drawing representation, and traditional Korean music ability in an early childhood education. ‘The Construction Meaning Comprehension Test’ is used to measure children’s language ability and it was developed and standardized by Seoul Community Rehabilitation Center(2009), ‘Traditional Korean Music Ability Test’ developed by Park Hyung-Shin(2006), ‘The Drawing Representation Inventory’ developed by Chi Sung-Ae(2001). In conclusion, a ‘Korean folktale based rhythm-word play activity’ has positive effects on language and traditional Korean music ability development. This study proves the validity of applying ‘ a Korean folktale based rhythm-word play activity’ in young children's education. Therefore, children’s language ability and traditional Korean music ability can be effectively increased by actively applying ‘a Korean folktale based rhythm-word play activity’ teaching-learning method in young children's education.

This paper presents an extension of the dynamic range in a complementary metal-oxide-semiconductor (CMOS) active pixel sensor (APS) using a stacked photodiode and feedback structure. The proposed APS is composed of two additional MOSFETs and stacked P+/N-well/P-sub photodiodes as compared with a conventional APS. Using the proposed technique, the sensor can improve the spectral response and dynamic range. The spectral response is improved using an additional stacked P+/N-well photodiode, and the dynamic range is increased using the feedback structure. Although the size of the pixel is slightly larger than that of a conventional three-transistor APS, control of the dynamic range is much easier than that of the conventional methods using the feedback structure. The simulation and measurement results for the proposed APS demonstrate a wide dynamic range feature. The maximum dynamic range of the proposed sensor is greater than 103 dB. The designed circuit is fabricated by the 0.35-μm 2-poly 4-metal standard CMOS process, and its characteristics are evaluated.

For successful restoration of visual function by a visual neural prosthesis such as retinal implant, electrical stimulation should evoke neural responses so that the information on visual input is properly represented. A stimulation strategy, which means a method for generating stimulation waveforms based on visual input, should be developed for this purpose. We proposed to use the decoding of visual input from retinal ganglion cell (RGC) responses for the evaluation of stimulus encoding strategy. This is based on the assumption that reliable encoding of visual information in RGC responses is required to enable successful visual perception. The main purpose of this study was to determine the influence of inter-dependence among stimulated RGCs activities on decoding accuracy. Light intensity variations were decoded from multiunit RGC spike trains using an optimal linear filter. More accurate decoding was possible when different types of RGCs were used together as input. Decoding accuracy was enhanced with independently firing RGCs compared to synchronously firing RGCs. This implies that stimulation of independently-firing RGCs and RGCs of different types may be beneficial for visual function restoration by retinal prosthesis.
