Digital decimation filters are used in various digital signal processing systems using ADCs, including digital communication systems and sensor network systems. When the sampling rate of digital data is reduced, aliasing occurs. So, an anti-aliasing filter is necessary to suppress aliasing before down-sampling the data. Since the anti-aliasing filter has to have a sharp transition band between the passband and the stopband, the order of the filter is very high. However, as the order of the filter increases, the complexity and area of the filter increase, and more power is consumed. Therefore, in this paper, we propose two types of decimation filters, focusing on reducing the area of the hardware. In both cases, the complexity of the circuit is reduced by applying the required down-sampling rate in two times instead of at once. In addition, CIC decimation filters without a multiplier are used as the decimation filter of the first stage. The second stage is implemented using a CIC filter and a down sampler with an anti-aliasing filter, respectively. It is designed with Verilog-HDL and its function and implementation are validated using ModelSim and Quartus, respectively.

김선희,Kim Sunhee 대한음성학회 2003 말소리 Vol.48 No.-

This paper presents a systematic description of exceptional pronunciations for automatic Korean pronunciation generation. An automatic pronunciation generator in Korean is an essential part of a Korean speech recognition system and a TTS (Text-To-Speech) system. It is composed of a set of regular rules and an exceptional pronunciation dictionary. The exceptional pronunciation dictionary is created by extracting the words that have exceptional pronunciations, based on the characteristics of the words of exceptional pronunciation through phonological research and the systematic analysis of the entries of Korean dictionaries. Thus, the method contributes to improve performance of automatic pronunciation generator in Korean as well as the performance of speech recognition system and TTS system in Korean.

The purpose of this study is to analyze the phenomenon in which the university policy, based reform system based on market, which is dominated by the state in the formation and change process of the university structural reform policy, is paradoxically maintained through a strategy - relational approach. This study examines the structural factors of the structural reform policies of the Korean university through a strategy-relational approach and to identify the mechanism of change process. The results of the analysis are as follows. First, it has an evolutionary nature in which reform is implemented as a historical legacy of previous policies. According to the characteristics and circumstances of each government, the degree of implementation of the reform was different from that of the state - led university structure reform policy, and it was adjusted to the direction of the times environment. Second, strategic choice was determined under the structural context of institutional reform policy and endogenous conditions of institution, resulting in a policy by period. The reform of the university structure in Korea is not based on the autonomous motivation and driving force of the university but rather by the government. Third, the main factors of the implementation of the reform should be conditional on the nature of the reform and the nature of the environment and the regime at the time. In other words, it can be understood that the reform can be promoted if the reform conditions are activated.

본 연구는 방학기간 동안 초등학교 저학년 빈곤가정 아동들에게 집단미술치료를 제공하고 사전-사후 PPAT(Person Picking an Apple from a Tree: 나무에서 사과따는 사람:이하 PPAT) 그림검사를 통해 그 영향을 확인하고자 하였다. 집단미술치료는 방학기간동안 적절한 교육과 여가활동을 갖기 어려운 저소득층 아동을 위해 복지사업기관의 심리정서지원 사업의 일환으로 제공되었다. 이를 위해 전문 미술치료사들은 선행 연구들을 근거로 단기 집단미술치료를 기획하였으며, 향후 복지기관이 제공하는 방학 프로그램에 미술치료사가 제공하는 집단미술치료가 지속될 수 있는 방안을 모색하고자 하였다. 집단미술치료에 총 158명의 아동이 참여하였고, 이중 사전-사후 PPAT 검사에 모두 참여한 아동 110명의 그림에서 분석에 적합하지 않은 그림 자료를 제외하고 총 102명 아동의 그림 자료를 FEATS (Formal Elements Art Therapy Scale: 형식척도)를 통해 분석했다. 집단미술치료는 방학기간의 특성상 학급 당 총 6회기로 한 회기 당 90분씩 2주 동안 집중적으로 제공되었다. 그 결과, 집단미술치료에 참여한 아동들의 PPAT 그림검사 사전-사후 반응에서, FEATS의 14가지 요소 중 사실성, 발달, 문제해결력, 3개 항목에서 통계적으로 유의한 변화를 확인하였다. 이는 집단미술치료가 참여 아동의 인지적 발달과 문제해결력에 긍정적 영향을 주었음을 확인하였다. The purpose of this study was to examine the implications of short-term group art therapy for the early elementary school students from low-income families using PPAT (Person Picking an Apple from a Tree) drawing test. It was specifically designed as a support program for children from low-income families, who had no proper access to educational enrichment opportunities and leisure activities during their summer break. The professional art therapists tried to lay out a basis of stable continuance of the group art therapy as a supporting program of the social welfare organization. Before and after the group art therapy, PPAT drawing test was administered. One hundred fifty-eight children were involved in the summer school, and 110 children participated in both pre- and pro-test of PPAT. After excluding eight children’s drawings due to their unsuitability for analysis, one hundred-two children’s drawings were analyzed by FEATS (Formal Elements Art Therapy Scale). Participants of the short-term intensive group art therapy showed three statistically significant changes out of 14 elements of FEATS in the pre- and post-test PPAT analysis: realism, development level, and problem-solving. The result of the study implied that the short-term intensive group art therapy is significantly effective to promote positive changes in children from low-income families in their cognitive development and problem solving ability.
