The main purpose of this study is to systematically classify words indicating pain in terms of their ranks in each subclass. This study is a part of developing a Korean Pain Measurement Tool. This study didnot include exploration of each word's dimension such as sensory or affective. Eighty three Korean words tentatively classified in 19 subclasses in previous study were used for this study. At least three to six words were included in each subclass and the words were randomly placed in which each subject indicates their rank of pain degree. One hundred and fifty nursing students and one hundred clinical nurses were requested to indicate the rank of each word. One hundred and sixteen students and eighty three nurses completed the ratings for analysis. The data were collected from June 1983 to July 1983. The data using ordinal scale were analyzed by Friedman ANOVA to test significant difference between rank means. All of pain words indicated significant rank mean difference in all of 19 subclasses. Some of the words were either cancelled or replaced by other words, or rearranged for their ranks. Subclasses of which words were cancelled were 1) Simple stimulating pain, 2) Punctuate pressure, 3) peripheral nerve pain, 4) radiation pain, 5) punishment-related pain, and 6) suffering-related pain. Subclasses of which words were replaced or rearranged were 1) incisive pressure, 2) constrictive pressure, 3) dull pain, 4) tract pain, 5) digestion-related pain and 6) fear-related pain. Four subclasses such as traction pressure, thermal, cavity pressure, and fatigue- elated pain indicated significant differences among rank means in each subclasses and showed no visible overlaps of the ranks among means. Further research is needed using high level measurement of pain degree of each word and more sophisticated analysis of the pain degrees. Three pain words which would be related to chemical stimulation were newly explored and included as a new subclass. Through this study, the total number of subclasses increases from 19 to 20 and the total number of Korean words in the scale decreases from 83 to 80.

This study explores the degree of velarization of English word-final /l/ (i.e., /l/-darkness) according to the lexical status. Lexical status is defined as whether a speech stimulus is considered as a word or a non-word. We examined the temporal and spectral properties of word-final /l/ in terms of the duration and the frequency difference of F2-F1 values by varying the immediate pre-liquid vowels. The result showed that both temporal and spectral properties were contrastive across all vowel contexts in the way of real words having shorter [l] duration and low F2-F1 values, compared to non-words. That is, /l/ is more heavily velarized in words than in non-words, which suggests that lexical status whether language users encode the speech signal as a word or not is deeply involved in their speech production.

Preliminary findings are reported from five experiments testing the perceived naturalness of word tokens whose vowel durations are altered. The stimuli were minimal pairs of English words ending in a voiced/voiceless plosive. Results show an asymmetric effect of shortening and lengthening of the vowel on the perceived naturalness of the word. Incremental shortening of vowel duration initially shows a stable degree of perceived naturalness but rapidly deteriorates beyond a certain point. On the contrary, only a small degree of lengthening of the vowel made the perceived naturalness of the word quickly decay, but there was a floor effect such that the perceived degree of naturalness does not lower beyond a certain level. Further, the tokens with the original vowel duration were not always scored higher than the stimuli with a small degree of shortening. Future studies should address the issue of speaking rate and the ratio between the vowel and the stop closure duration to better understand the phenomenon. The issue investigated here has implications on the role of prototypical exemplars in the perception of phonotactic naturalness.

This study investigates passenger-authored online reviews of airline services using social network analysis to compare the differences in customer perceptions between full service carriers (FSCs) and low cost carriers (LCCs). While deriving words with high frequency and weight matrix based on the text analysis for FSCs and LCCs respectively, we analyze the semantic network (betweenness centrality, eigenvector centrality, degree centrality) to compare the degree of connection between words in online reviews of each airline types using the social network analysis. Then we compare the words with high frequency and the connection degree to gauge their influences in the network. Moreover, we group eight clusters for FSCs and LCCs using the convergence of iterated correlations (CONCOR) analysis. Using the resultant clusters, we match the clusters to dimensions of two types of service quality models ($Gr{\ddot{o}}nroos$, Brady & Cronin (B&C)) to compare the airline service quality and determine which model fits better. From the semantic network analysis, FSCs are mainly related to inflight service words and LCCs are primarily related to the ground service words. The CONCOR analysis reveals that FSCs are mainly related to the dimension of outcome quality in $Gr{\ddot{o}}nroos$ model, but evenly distributed to the dimensions in B&C model. On the other hand, LCCs are primarily related to the dimensions of process quality in both $Gr{\ddot{o}}nroos$ and B&C models. From the CONCOR analysis, we also observe that B&C model fits better than $Gr{\ddot{o}}nroos$ model for the airline service because the former model can capture passenger perceptions more specifically than the latter model can.

[감성지향 제품] 디자인에 있어서는 디자이너가 제품을 통해 표현하려는 이미지와 사용자가 제품을 통해 느끼는 감성적 평가와의 사이에 존재하는 갭(gap)이 문제가 되고 있는데, 이 갭을 해소하는 데에 있어 디자인 과정에서 활용되어진 이미지화상들과 디자인 평가를 위해 사용되었던 감성적 평가어 사이와의 관련도에 관한 정보는 특히 유효하다. 본 연구에서는 이러한 관련도 정보에 근거하여, 이미지 화상 및 이미지어 탐색을 통해 스타일링 디자인을 지원하는 감성검색시스템을 제안한다. 본 시스템에 있어서 관련도 정보는 이미지어와의 유사도를 유의어 계수로 상정한 퍼지 시소러스에 의해 표현된다. 또한 이미지어 사이의 유사도는 이미지 화상 평가를 기초로 산출된다. 이미지 탐색은 검색 중시도(weight)를 파라메터로한 퍼지 시소러스 전개의 알고리즘에 의해 실행되며, 탐색 모드로서 이미지어 상호간, 이미지어에서 이미지화상, 이미지 화상에서 이미지어, 이미지 화상간의 합계 네 종류의 모드가 제공 된다. 또한 이들 모드간의 이행은 직접 조작형 인터페이스에 의해 실행되며, 이로 인해 아이디어 탐색단계에 있어서의 디자이너의 발상과정이 원활하게 지원된다. 시스템은 감성적 평가의 계측 유니트와 갭의 연산, 가시화 유니트로부터 구성되며, 조작의 일관성을 유지하기 위해 통일적인 인터페이스의 환경 하에서 구축하였다.

The purpose of this article is to study the effect of finger play teaching method on the reproduction of children's English words. The hypotheses are as follows: 1) there will be the difference of the reproduction of children's English words between the experimental group(that is taught by finger play teaching method) and the controlled group (that is taught by only oral teaching method). 2) there will be the difference of children's retention capacity of reproducing English words between the experimental group and the controlled group, The researcher made the time series data The measure tool was the check list for reproduction test of children's English words that was made by Run-Soon Oh and J. Eden(2004). The researcher analyzed the data using the Repeated Measures ANOVA and the Analysis of Covariance. The findings of research are as follows: 1) the more the frequency of teaching increases, the more there are the difference of reproducing English words according to frequencies and groups. The reproduction capacity of the experimental group is better than that of the controlled group. A degree of statistical significance is p<.001. 2) The difference of retention capacity of reproducing English words between the experimental group and the controlled group is a statistical significant, p<.05. The experimental group is better than the controlled group.
