  • The purpose of this study was to examine the effects of sensibility and compatibility from function sounds of mobile phones. For this purpose, the present study extracted sensibility adjectives and carried out sensibility evaluation to identify the sensibility factors in the function sounds of mobile phones. And 65 sound sources out of six categories were investigated for 27 subjects. The result showed that two dominant sensibility factors were the duration and the melody pattern of the sound sources. The compatibilities of opening and closing sounds were evaluated lowly with short duration and quick tempo. Especially, the most of the subjects preferred more attractive and longer opening sounds than other function sounds. Another finding was that the short sounds with melodies were preferred for cancellations and alerts, unliked the commonly used sound sources in industry and other traditional electronic products.

  • The purpose of our study was to provide effective speech evaluation items examining the variables of speech that successfully predict the speech intelligibility in CP children. The subjects were 55 children with spastic type cerebral palsy. As for the speech evaluation, we performed a speech subsystem evaluation and a speech intelligibility test. The results of the study are as follows. The evaluation task for the speech subsystems consisted of 48 task items within an observational evaluation stage and three levels of severity. The levels showed correlations with gross motor functions, fine motor functions, and age. Second, the evaluation items for the speech subsystems were rearranged into seven factors. Third, 34 out of 48 task items that positively correlated with the syllable intelligibility rating were as follows. There were four items in the observational evaluation stage. Among the nonverbal articulatory function evaluation items, there were 11 items in level one. There were 12 items in level two. In level three there were eight items. Fourth, there were 23 items among the 48 evaluation tasks that correlated with the sentence intelligibility rating. There was one item in the observational evaluation stage which was in the articulatory structure evaluation task. In level one there were six items. In level two, there were eight items. In level three, there was a total number of eight items. Fifth, there was a total number of 14 items that influenced the syllable intelligibility rating. Sixth, there was a total number of 13 items that influenced the syllable intelligibility rating. According to the results above, the variables that influenced the speech intelligibility of CP children among the articulatory function tasks were in the respiratory function task, phonatory function task, and lip and chin related tasks. We did not find any correlation for the tongue function. The results of our study could be applied to speech evaluation, setting therapy goals, and evaluating the degree of progression in children with CP. We only studied children with the spastic type of cerebral palsy, and there were a small number of severe degree CP children compared to those with a moderate degree of CP. Therefore, when evaluating children with other degrees of severity, we may have to take their characteristics more into account. Further study on speech evaluation variables in relation to the severity of the speech intelligibility and different types of cerebral palsy may be necessary.

  • Hand function evaluations are an important element of the assessment process in physical rehabilitation settings. The purpose of this study was to investigate hand function evaluation. Subjects consisted of 20 with spastic cerebral palsy(mean age = 9.8, SD = 1.6) and 20 with athetoid cerebral palsy(mean age = 9.6, SD = 2.3). Two groups of subjects were tested twice(pretest and posttest) by the JHFT to measure evaluations of hand function. These findings suggest that on four subtests - writing, card turning, large heavy objects and Stacking Checker-the spastic cerebral palsy perform significantly faster than athetoid cerebral palsy. But there were no significant differences between the pretest and posttest in spastic and athetoid cerebral palsy. To see the statistical differences in the experimental results was done using origin V. 3.0.

  • A modified grey clustering method is presented to systematically evaluate the risk of water inrush in karst tunnels. Based on the center triangle whitenization weight function and upper and lower limit measure whitenization weight function, the modified grey evaluation model doesn't have the crossing properties of grey cluster and meets the standard well. By adsorbing and integrating the previous research results, seven influence factors are selected as evaluation indexes. A couple of evaluation indexes are modified and quantitatively graded according to four risk grades through expert evaluation method. The weights of evaluation indexes are rationally distributed by the comprehensive assignment method. It is integrated by the subjective factors and the objective factors. Subjective weight is given based on analytical hierarchy process, and objective weight obtained from simple dependent function. The modified grey evaluation model is validated by Jigongling Tunnel. Finally, the water inrush risk of Shangjiawan Tunnel is evaluated by using the established model, and the evaluation result obtained from the proposed method is agrees well with practical situation. This risk assessment methodology provides a powerful tool with which planners and engineers can systematically assess the risk of water inrush in karst tunnels.

  • 피처선택, 혹은 변수 선택은 피처의 수가 매우 많은 고차원 데이터에서 주어진 주제와 연관성이 높은 피처를 선별하는 과정으로서, 데이터의 차원수를 낮추어 군집분석이나 분류 분석 등을 용이하게 하는데 중요한 기법이다. 많은 수의 피처들 중에서 일부의 피처를 선별하기 위해서는 피처들을 평가하기 위한 도구가 필요하다. 현재까지 제안된 도구들은 대부분 확률이론이나 정보이론에 기초하여 만들어졌기 때문에 하나의 피처, 즉 1차원 데이터만을 평가할 수 있다. 그러나 피처들 간에는 상호작용이 있기 때문에 하나의 피처를 평가하기 보다는 여러 피처들의 집합, 즉 다차원 데이터를 평가할 수 있어야 효과적인 피처 선택이 가능하다. 본 연구에서는 확장된 거리 함수를 이용하여 1차원 데이터 평가용으로 제안된 FSDD 평가 함수를 다차원 데이터에 대한 평가가 가능하도록 개선하는 방법에 대해 제안하였다. 본 연구에서 제안한 접근법은 다른 1차원 데이터 평가함수에도 적용이 될 수 있을 것으로 기대된다.

  • The purpose of this study was to discover a conceptual framework and evaluation process of apparel quality by means-end chain theory. The theoretical study was conducted to find out a conceptual framework and build a hypothetical evaluation process model of apparel quality. Apparel quality was perceived associative network called a means-end chain and was evaluated in several stages. A conceptual framework of apparel quality evaluation was organized into hierarchical relationships among four different dimensions: physical attribute, physical function, instrumental performance, and expressive performance. The means-end structure linked tangible physical attributes and function to more abstract instrumental and expressive performance. A hypothetical evaluation process model linked dimensions of apparel quality to the selected means-end relationship. Different consumers had different means-end chains for the same apparel. Therefore different subjects are likely to have different evaluation paths. From this study we can suggest an evaluation process model of apparel quality.
