Korean Classical Music, as the abbreviated wording for 'Korean Music', is being used as the indicating phraseology for our traditional music that distinguishing from Western Music, the foreign music or foreign-styled popular music. Since such Korean Classical Music has the different acoustic characteristics from Western Music, it needs its own performance space for the special exclusive-use of Korean Classical Music. Likewise, even though the demand for the performance space of special exclusive-use for Korean Classical Music where Korean Classical Music is rendering, is on increasing tendency due to the increase of national concern about traditional culture art, since it is being planned without any concrete standard or method that gratifies the supreme listening condition, it is the real situation that a securement of the satisfying acoustic condition is very difficult, after the completion of construction. On such viewpoint, in order to evaluate the acoustic characteristics of the performance space of special exclusive-use for Korean Classical Music, based on the subjective response which reflects human being's psychological attribute at first, this Study has attempted to extract the proper evaluation vocabulary for appraisement on Korean Classical Music. The abstracted vocabulary in such way would be used significantly for Subjective Response Evaluation in order for the evaluation on the Acoustic Characteristics of the performance space of special exclusive-use for Korean Classical Music.

After the Industrialization of 1960s, while it has greatly contributed to the industrial development owing to acceleration of mechanization, but it is real situation that the countermeasure to Noise Damage generating at the loud noise workshop is scarcely made. Especially, the Instrument-Noise made at factory and workplace is so shocking and repeatedly reiterating terrible noise that most of the spot workers are forcedly imposing such dangers as the severe unpleasant feeling and hearing impairments. On such point of view, this Research has attempted to extract the proper Rating Vocabulary in order for valuation on Instrument Noise made at the terrible noise-workplace, therefore it is considering that those extracted Vocabularies could be utilized as the useful materials for appraisal on Instrument Noise, also for establishment of Regulation-Standard with regard to Acoustic Psychology Experimentation and Instrument Noise.

For the accurate evaluation of traffic noise with various spectrums and fluctuation characteristics, evaluation systems should reflect not only physical quantities but also the psychological respects of individual persons. In this study, adequate words for evaluating traffic noise have been extracted by reviewing the existing vocabularies and augmenting this with the results of a questionnaire prepared especially for apartment dwellers. As a result of this study, followings are suggested. 1) Vocabularies such as 'disagreeable', 'annoying', 'strident', 'disturbed', 'irritate', 'unpleasant', 'dislike' are classified into the first factor by factor analysis. 2) As a result of surveying overlapping vocabularies for each sound sources, 'noisy', 'annoying', strident', 'unpleasant', 'loudness' are main unpleasant vocabularies to franc noise occurring in our domestic apartment houses.

In this paper, we propose a new evaluation methodology which can more clearly show the performance of the allophone modeling algorithm generally used in large vocabulary speech recognition. The proposed evaluation method shows the running characteristics and limitations of the modeling algorithm by testing how the variation of phonetic environments of training data affects the recognition performance and the desirable number of free parameters to be estimated. Using the method, we experiment results, we conclude that, in vocabulary-independent recognition task, the phonetic diversity of training data greatly affects the robustness of model, and it is necessary to develop a proper measure which can determine the number of states compromizing the robustness and the precision of the HMnet better than the conventional modeling efficiency.

1960년대 산업화 이후 기계화가 가속되어 산업발달에 많은 기여를 하였으나 고소음 작업장에서 발생하는 소음피해에 대한 대책은 거의 없는 실정이다. 특히 공장 및 작업장에서 발생하는 기계소음은 반복적으로 되풀이되어 충격적이며, 강한 소음으로 대부분의 현장 작업자들은 높은 불쾌감과 청력장애의 위험을 부담하고 있다. 이러한 관점에서 이 연구는 고소음 작업장에서 발생하는 작업기계 소음을 평가하기 위한 적정 평가어휘를 추출하고자 했으며, 이렇게 추출된 어휘는 작업 기계소음을 평가하기 위한 음향심리 실험 및 기계소음 규제기준 설정을 위한 유용한 자료로 활용될 수 있을 것으로 사료된다.

'Emotional value' has been a buzz word for design and ergonomics in the era of business innovation. However, the complication of 'emotion' in terms of literal and practical meaning has made it a challenging but confusing task for designers to develop a new product with emotional value. 'Sensibility' and 'emotion' are interchangeable terms to describe human feeling ('gamsung' in Korean). The confusion reached at its peak with Korean terms. Even scholars in Korean language, psychologists, ergonomists, and designers are bewildered at the choice of proper expression for human feeling in both Korean and English. The difficulty could explain the problems in 'sensibility ergonomics' in Korea. The purpose of this paper is to provide both fundamental and satisfying information with people in the area of 'sensibility ergonomics'. Therefore, in this paper, a number of articles and books on sensibility, psychology, sensibility ergonomics, and design were reviewed to clarify the meaning of sensibility and relationship among similar words that have been used with unintentional misunderstanding. Also many adjectives on human sensibility were collected and complied for the use of sensibility evaluation.

As speech is the human being's most natural communication medium, using it gives many advantages. Currently, most user interfaces of a computer are using a mouse/keyboard type but the interface using speech recognition is expected to replace them or at least be used as a tool for supporting it. Despite the advantages, the speech recognition interface is not that popular because of technical difficulties such as recognition accuracy and slow response time to name a few. Nevertheless, it is important to optimize the human-computer system performance by improving the usability. This paper presents a set of guidelines for designing speech recognition interfaces and provides a method for evaluating the usability. A total of 113 guidelines are suggested to improve the usability of speech-recognition interfaces. The evaluation method consists of four major procedures: user interface evaluation; function evaluation; vocabulary estimation; and recognition speed/accuracy evaluation. Each procedure is described along with proper techniques for efficient evaluation.

본 연구는 2차 법률정보 전문 데이터베이스 구축을 위한 기초연구(권기원, 노정란, 1998, 한국문헌정보학회지, 32(3))에서 밝혀진 법률정보의 특성을 근거로 알고리즘을 개발하고 알고리즘에 의한 모형 통제어 데이터베이스를 구축하여 통제어 색인 시스템과 자연어 색인 시스템의 검색효율을 비교 평가한 것이다. 연구 결과 2차 법률 정보 전문 데이터베이스에서 통제어 색인 시스템은 재현을, 정확률, 자연어 시스템이 검색하지 못한 고유한 적합 문헌을 검색하는 능력에 있어서 자연어 색인시스템보다 높은 효율을 나타내었다. 또한 일반적으로 가중치를 부여하거나 접근점을 추가할 경우 데이터베이스의 정확률이나 재현율의 향상을 가져올 수 있다고 보고 있으나, 2차 법률정보 전문 데이터베이스에서는 법률정보라는 특정 지식 분야의 특성으로 인하여 가중치를 부여하거나 접근점을 추가한 경우에도 재현율과 정확률의 향상을 나타내지 않는다는 사실이 맞혀졌다. 그러므로 정보시스템 설계자는 시스템을 단순히 언어학적, 통계학적 방법으로 접근하기보다는 정보전문가와 주제전문가가 인식하고 있는 각 주제분야의 고유 지식을 시스템에 내장시키는 것이 필요하다고 할 수 있다.

인터넷 기술과 모바일 등의 기기 발전으로 교육환경도 전통적이고 수동적인 방식에서 학습자 중심의 능동적인 방식으로 변화하고 있다. 이에 따라 학습자 개개인의 수준별 맞춤 교육의 역할도 커지고 있으며, 이에는 개별 학습자의 프로파일 구축이 중요하다. 기존의 ICT 기반 맞춤형 영어 교육의 다수는 어휘에 초점을 맞추고 있으며, 학습 콘텐츠에 대한 분석에 많은 노력을 기울이고 있다. 본 논문에서는 보다 정밀하게 사용자의 학습상태를 정의하기 위하여 단어와 문법을 대상으로 학습 상태를 구축하였다. 그리고 학습자가 특정 콘텐츠에 얼마나 익숙한지를 알려주는 콘텐츠에 대한 숙련도 메트릭을 정의하였다. 이후 실제 영문 에세이 데이터를 기반으로 사전학습을 통하여 사용자들의 숙련도를 결정하고, 시뮬레이션을 통하여 평가 에세이 데이터에 대하여 적용성이 있음을 보였다. 또한 본 연구에서 제안한 분석기법은 학습상황에 대하여 통계치나 그래프를 제공하고 학습자 수준에 적합한 학습자료를 생성하는데 필요한 데이터를 제공할 수 있다.

Recently, in accordance with the buildings are rapidly becoming to high-stories, large-sizes, and since the case that noise of equipment machinery, tool itself infringes the life environment is on increasing, this is becoming to the object of civil appeal. Accordingly, in order to set up a countermeasure against such equipment machinery noise, even a systemic evaluating method is required, up to now while the appraisal that considering on the physical characteristic only had been done, but the characteristic about subjective valuation was not reflected as yet. Therefore, in this research, through the 1st, 2nd Psycho-Acoustics Experiments, the 30 vocabularies were extracted for evaluation of the construction equipment noise. As the result of Element Analysis, the 3 Elements were extracted from these vocabularies, and it could be understood that these Elements have been trustfully selected. It is now considering that the extracted vocabularies as per the above result would be used to Psycho-Acoustic Evaluation on Equipment Noise, and Psycho-Acoustics Experiment.
