본 연구에서는 PCS 이동전화의 객관적 통화품질평가 척도개발을 위한 기초연구로 기존의 CD(Cepstral Distance), MSD (Mel Spectral Distance), BSD(Bark Spectral Distance), PSQM (Perceptual Speech Quality Measure) 척도를 적용하여 그 성능을 비교 분석하였다. 이 척도들을 실제환경에서 수집된 PCS 음성데이터에 대해서 적용하였고 이 결과치와 청취자들의 평가 반응에 의해 얻어진 MOS 결과치와의 상관성을 조사하였다. 실험 결과, BSD와 PSQM 척도의 상관성이 0.81, 0.84로 나타나 CD, MSD보다 성능이 더 우수함을 보였다.

본 연구에서는 특정 대상에 대한 사람들의 심리적인 색채반응을 측정할 수 있는 색채감성척도(PCS)를 개발하고 이것을 색채 감성 이미지의 평가에 어떻게 이용하는가를 보여주고자 한다. 색채심리에 기초한 색채감성척도(PCS)는 NCS와 ISCC-NBS 색명법에 의거한 색상과 톤의 개념으로 구성되었으며 기본형과 상세형의 두 가지가 개발 되었다. 표준화된 색채감성척도는 각 사람들마다 다르게 나타나는 색에 관한 이미지나 색에 대한 심리적인 선호반응을 객관적으로 측정할 수 있는 척도로 활용될 수 있다. 본 연구에서는 선호색, 선호의상색, 선호 화장품 색을 나타내는데 PCS가 어떻게 활용되는가를 보여주었다. PCS를 이용한 색채 감성 이미지는 Color Image Palette를 이용하여 각각의 특성을 비교할 수 있도록 제시되기도 하였다. 색채 경험에 대한 광학적이거나 물리적인 속성이 아닌 심리적인 특성을 평가하고 서로 다른 집단의 반응을 비교 평가하는데 PCS와 유용한 도구가 될 것이다.

This study is about the scale to evaluate the data of the countermeasures in the 'simulation based government exercise' (tentative name). The criteria and weighting of the scale is a standard for evaluating the data of each agency input. This maintains the objectivity and consistency of the evaluation, which complements the subjective evaluation of the observer. Therefore, the criteria should accommodate the purpose of the government exercise evaluation, the possibility of measurement in the simulation environment, the objectivity, no-duplication and causality between criteria, and the grade applying the evaluation results, and the weighting should be set. In this study, three major criteria of timeliness, accuracy, and appropriateness is set up for the evaluation scale and it consists of sub-criteria classified into three classes below respectively and the concept of it was defined. The weighting was calculated by AHP analysis considering the hierarchical structure of it. When this evaluation scale is applied to the 'simulation based government exercise' in the future, it will be possible to secure consistency and objectivity of the evaluation of measures by integrating the quantified evaluation into the observation evaluation and to conduct AAR by scientific techniques.

As a tiered system of supports, School-Wide Positive Behavior Support (SWPBS) is an evidence-based practice in the educational system of Korea. An important aspect of SWPBS is the ongoing progress monitoring and evaluation of implementation fidelity. This study aimed to develop and validate the Korean Tier 3 School-Wide Positive Behavior Support Implementation Fidelity Checklist (KT3-FC). The preliminary KT3-FC consisted of a 37-item, 6-factor checklist. In the first phase of the study, 10 experts reported that the range of content validity of the KT3-FC was adequate. In the second phase of the study, 185 teachers (52 men and 133 women) who implemented SWPBS completed the KT3-FC, Individualized Supports Questionnaire, School Climate Questionnaire, School Discipline Practice Scale, and PBS Effectiveness Scale. An exploratory factor analysis resulted in a 5-factor structure, with 20 items, instead of 37 items, consisting of: (a) progress monitoring and evaluation of the individualized supports, (b) provision of supports by aligning and integrating mental health and SWPBS, (c) crisis management planning, (d) problem behavior assessment, and (e) establishment of individualized support team. The internal consistency of the KT3-FC was good (full scale α = .950, sub-factor α = .888 ~ .954). In addition, the KT3-FC showed good convergent validity, having statistically significant correlations with the Individualized Support Questionnaire, School Climate Questionnaire, School Discipline Practice Scale, and the PBS Effectiveness Scale. Finally, the confirmatory factor analysis showed that the 5-factor model of the KT3-FC had some good model fits, indicating that the newly developed fidelity measure could be a reliable and valid tool to assess the implementation of Tier 3 supports in Korean schools. Accordingly, the KT3-FC could contribute to implement SWPBS as an evidence-based behavioral intervention for Korean students.

Image dehazing has been extensively studied, but the performance evaluation method for dehazing techniques has not attracted significant interest. This paper surveys many existing performance evaluation methods of image dehazing. In order to analyze the reliability of the evaluation methods, synthetic hazy images are first reconstructed using the ground-truth color and depth image pairs, and the dehazed images are then compared with the original haze-free images. Meanwhile we also evaluate dehazing algorithms not by the dehazed images' quality but by the performance of computer vision algorithms before/after applying image dehazing. All the aforementioned evaluation methods are analyzed and compared, and research direction for improving the existing methods is discussed.

The purpose of this study was to examine the validity of the Teacher's Scale for Gifted Preschool Children(TSGPC). Participation of this study were 357 preschool children and their parents and teachers from Seoul, Ulsan, Daegy, Gwangiu & Daejeon. Data were analyzed by exploratory factor analysis, Pearson's r, t-test and Cronbach's ${\alpha}$. Results are as follows. (1) exploratory factor analysis of TSGPC revealed that a 5-factor solution (academic ability, creativity, task commitment, artistic talent, and leadership) was the best fit. (2) Correlations between TSGPC and parental rating scale for young children's giftedness were significant. (3) Scores of TSGPC between gifted children and general children were significantly different (4) Cronbach's ${\alpha}$ ranged from .82 and .91 for subscale of TSGPC and .93 for the total scale. These results show that the Teacher's Scale for Gifted Preschool Children is quite reliable and valid measure.

본 논문은 Chidamber와 Kemerer가 제안한 객체지향 설계를 위한 척도를 바탕으로 이를 확장하여 클래스 상속 구조의 유지보수성을 이해성과 변경성 측면에서 측정하는 새로운 객체지향 척도를 제안했다. 그리고 클래스 상속 구조의 예를 들어 비교 평가를 함으로써 Chidamber와 Kemerer의 척도 및 Henderson-Sellers의 척도보다 우수함을 보였다.

The purpose of the present study was to evaluate the effect of 7-point interval scale(EAI) and visual analogue scale(VAS) on perceptual judgement and the reliability of severity on voice problems by dysphonic speakers. 30 undergraduate students studying communication disorder were enrolled in the perceptual evaluation. Those listeners judged overall voice severity within the anchored(condition 1) and non-anchored scales(condition 2) for vowel prolongation and reading tasks by 25 speakers with voice disorder. The results of this study showed that the scores by VAS was significantly higher than EAI in both condition 1 and condition 2 for vowel prolongation and reading task. However, the scores by EAI method was higher than by VAS method on voice severity of vowel prolongation (condition 1) and reading task(condition 2). These results suggest auditory-perceptual scaling procedures must be more studied in the aspects of clinical application of voice disorder.

본 연구는 생활 소음이 유발하는 유해성을 객관적으로 평가할 수 있는 감성 척도를 개발하고, 그 척도를 이용하여 생활 소음과 소음에 대한 감성간 관계를 반영하는 감성 지수를 도출하고자 수행되었다. 먼저 소음에 대한 주관적 느낌을 잘 기술해주는 27 개의 형용사를 선정한 뒤, 세 가지의 실제 주거 소음을 들려주며 소음에 대한 감성을 27 개의 형용사에 대해 평가하게 하였다. 이 결과에 대한 요인분석을 실시하여 '지배성', '쾌/불쾌', '각성' 차원의 세 개 차원으로 구성되는 14 개의 최종적 소음 감성 척도를 개발하였다. 다음으로 실제 주거 생활에서 소음과 감성간 관계를 알아보기 위해 실제로 4 가지의 주거 소음을 들으면서 인지적 과제를 수행하게 하여 소음에 대한 느낌을 소음 감성 척도상에 평가하게 하는 실험을 실시하였다. 이 결과 소음의 크기가 증가할수록 소음에 대한 감성이 부정적으로 나타나는 직선적 관계가 얻어졌고. 이를 기초로 일차 방정식 형태의 소음-감성 지수를 도출하였다.
