음악 제작 과정의 마지막 단계는 마스터링이다. 과거의 마스터링은 단순히 컴프레서(Compressor)와 리미터(Limiter)를 이용하여 각 트랙의 오디오 레벨을 일률적으로 매칭시키는 것이었지만, 디지털 장비의 꾸준한 발전으로 많은 마스터링 제작자들은 이퀄라이저(Equalizer)와 컴프레서를 기본으로 리버브(Reverb), 딜레이(Delay), 그리고 디더(Dither)를 이용하여 모든 트랙을 하나의 통일된 분위기로 제작하는 방식으로 진보하고 있다.

초등학교에서는 여러 가지 이유로 교수학적 변환이 불가피하다. 수학에서는 덧셈과 곱셈은 이항연산, 뺄셈과 나눗셈은 단항연산으로 다루고 있는 반면, 초등에서는 사칙연산 모두를 이항연산으로 취급하는 교수학적 변환을 시도한다. 그런데 사칙연산의 개념을 '익힌다는 것'은 개념이 어떻게 도입되는가가 더 중요하게 부각된다는 점에서 개념을 이해하는 것과는 다르다. 이에 본 연구에서는 자연수와 분수의 사칙연산을 개념 익히기(개념이 어떻게 도입되고 있는지와 연산 선택의 문제)와 연산 사이의 연결이라는 두 가지 관점으로 분석하여, 자연수와 분수의 사칙연산 지도와 관련된 몇 가지 시사점을 도출하였다. 분수의 나눗셈에서는 상황을 바탕으로 연산을 선택하지 않고 곧장 분수의 곱셈과의 연결을 시도했다는 것과 분수의 나눗셈을 그 자체로 이해하기 위해서는 5학년 2학기와 6학년 1학기에 걸쳐 제시되어 있는 분수의 나눗셈을 통합해야 한다는 것 등이 그것들이다. 이는 후속 교과서 개발 시 유용한 참고자료가 될 것으로 판단된다.

Peer assessment is the process of assessment of students by other students and one form of innovative assessment. It actively involves students in the assessment process and is generally agreed that such involvement enhances the quality and effectiveness of the learning process, since assessing something and benchmarking process is a powerful aid to mastering it themselves. It is more effective on the hard courses for them to understand. In this article we present a peer assessment technique which was applied to students enrolled in a mathematical statistics course and a historical course. In order to measure the effectiveness of the technique, students had to evaluate their colleagues based on predefined criteria and a comparison is presented between the instructor assessments and the peer assessment.

This study examined the spontaneous utterances of 20 1-2 year old Korean-Chinese children in Yanji, China by videotaping their spontaneous natural speech during interaction with his/her caregiver for 30 minutes on 4 separate occasions. Utterances were transcribed and coded by nominative and accusative case markers; then analyzed by grammatical functions. Results showed that the order and pattern of the acquisition of the case marking system of Korean-Chinese bilinguals differed from that of Korean monolinguals. Bilinguals used the accusative marker -lul earlier than the nominative marker-ka and overextended the accusative marker more often than the nominative marker. These results are consistent with those of Gathercole (in press) who found that bilingual children differed from monolinguals in mastering grammar.

In this paper, we explored the possibilities of embedding Qualitative Reasoning techniques, the Qualitative Process Theory (QPT), and its implementation in the field of inorganic chemistry. The target field of implementation is Qualitative Chemical Analysis and Laboratory Simulation. By embedding such technique in this education software we aim to combine theory and practice into a single package. The system, are able to generate reasoning and explanation based on chemical theories, helping student in mastering basic chemistry knowledge and practical skill as well. We also review the suitability of embedding QPT techniques into chemistry in general, by comparing some examples from both fields.

Mastering a musical instrument for an unskilled beginning learner is not an easy task. It requires playing every note correctly and maintaining the tempo accurately. Any music comes in two forms, a music score and it rendition into an audio music. The proposed method of assisting beginning music players in both aspects employs two popular pattern recognition methods for audio-visual analysis; they are support vector machine (SVM) for music score recognition and hidden Markov model (HMM) for audio music performance tracking. With proper synchronization of the two results, the proposed music learning assistant system can give useful feedback to self-training beginners.

This study examines the significance of digital fabrication of scaled physical models in the digital design process and highlights the integration of design computing and digital fabrication in architectural education. Advances in CAD/CAM technologies have increasingly influenced building design and construction practices by allowing the production of complex forms that were once difficult to design and construct using traditional technologies. At the advent of digital architecture, schools of architecture introduced digital technologies to their curriculum, focusing more on design computing than digital fabrication, preventing students from completely mastering digital technologies. The significance of digital fabrication for scaled physical models as a design media within the digital design loop is discussed. Two case studies of leading schools of architecture that are successful in building the bridge between both areas are given. These focus on the curricular structure to integrate both areas within design studios. Finally, a curricular structure offering students a balanced approach to these areas of knowledge is proposed based on what was learned from these case studies.

본 논문에서는 광디스크 메모리의 재생성능에 주요한 영향을 미치는 jitter를 향상시키는 방법이 검토되었다. 광디스크 제조공정에 있어서 타공정의 변수를 고정한 상태에서 단일의 조작을 통해 jitter value를 저감화시키기 위해 펄스 폭 조정기를 제작하였다. 펄스 폭 조정기폭 적용하여 입력신호의 level을 조정한 결과 6.9%의 최소 jitter value를 확보하였다.

The purpose of this paper is to let people know that current digital transition in digital cinema industry world wide is inevitable and radical. The parties concerned in the domestic film industry have not paid attention to this digital wave yet, In this research, we investigated about current situation of digital cinema industry and proposed digital film mastering, transport, technology, and business related models in digital cinema. To increase productivity of making a movie, we searched areas needing standards, created quality managing program, and proposed organization systems to perform those plans.

The purposes of this study are to: (1) Compare the vowel production of English front vowels produced by Korean speakers using regional dialects and; (2) Investigate and compare the effectiveness of pronunciation training for each regional dialect group. To test these objectives, the English front vowels produced by five Youngnam dialect male speakers, five Youngnam dialect female speakers, five Kangwon dialect male speakers, and five Kangwon dialect female speakers were scrutinized. These dialect groups' vowel formants and length of English front vowels were evaluated, and the post-pronunciation training values were compared with those of pre-training values. The results indicate that pronunciation training is more effective for Youngnam dialect speakers, whilst both dialect groups have more success mastering the pronunciation of /${\varepsilon}$/ over /${\ae}$/.
