This study aims to design ergonomic warning sound that is not confusing and enhancing preference. Four factors of the warning sound represented as interval, chord, reverberation and pitch were selected as independent variables. And, perceived urgency, perceived criticality, degree of confusion and user preference are measured as dependent variables. An experiment was conducted in silent lab environment. Warning sounds were given in 90dB constantly to subjects through stereo speakers. A statistical analysis revealed that interval was significant for perceived urgency; also interval and chord were both effective for perceived criticality. Pitch, interval, chord and the interaction between pitch and chord were effective in degree of confusion, so were reverberation, the interaction between reverberation and pitch and the interaction between reverberation and chord for preference. This study characterized the situation under which warning sounds are required into three types in terms of urgency and criticality; and found the right warning sound that the subjects perceived to best represent the situation through the validation study. These findings are expected to help the designer choose the right warning sound according to the situational contexts in which such warning sounds are implemented.

교통량조사 방법은 루프검지기와 피에조센서를 주로 많이 사용하여 차량의 숫자만을 파악하여 교통주기를 계산하는 방법을 사용하나 교통량을 파악하는 방법은 단순한 교통량에만 국한되는 것이 아니라 다중교통특성인 진입로의 길이, 도로의 폭, 보행자의 수, 통과차량수, 지체차량수 등 관련되는 교통대안을 총 망라하여 새로운 교통량인 혼잡도라는 개념을 대표대안으로 선정하면 바로 교통주기에 적용할 수 있다. 본 논문에서는 서로 관련성이 없는 교통대안들을 AHP 방법을 사용하여 교통주기 계산에 즉시 사용할 수 있는 공통 분모인 새로운 교통대안을 찾아내는 알고리즘을 개발하고 이를 새로운 교통량 개념인 혼잡도라는 교통량을 찾아내는 퍼지센서 알고리즘을 구성하는데 적용한다. 시뮬레이션을 통해 타 교통제어방법과 비교하여 지체차량시간이 줄어듬을 보여준다.

교통의 혼잡량이라든가 공기의 쾌적도등을 측정할 때는 상징적인 정보량을 이용한 퍼지 센서 알고리즘을 사용한다. 그런데 퍼지센서를 구현할 경우 몇 개의 상징적인 정보량을 퍼지 규칙으로서 종합하여 출력을 산출하는데 상징적인 정보량을 퍼지 규칙이라는 막연한 방법을 사용하므로서 정확하지 못한 결과를 산출 할 수 밖에 없다. 따라서 본 논문에서는 퍼지 규칙으로 퍼지센서를 구현하는 방법이 아닌 계층분석 방법이라는 분석적인 방법을 이용하여 퍼지센서를 구현하였고 이를 검증하기 위하여 퍼지 규칙방법의 퍼지센서와 계층분석방법의 퍼지센서를 교통량 제어에 적용하여 많은 통과차량수의 검증을 통하여 비교하여 보았다

Purpose: The purpose of this study was a comprehensive understanding about maternal transition in mothers with high risk newborns according to the degree of situational meaning. Method: A methodological triangulation that combines qualitative and quantitative methods was used. The situational meaning of a high risk newborn mother was identified using a Family Meaning Attribution Scale. According to the degree of situational meaning, in-depth interviews were conducted at 3 time periods postpartum: between 3-10 days after childbirth, around the time of the newborn's discharge, and between 10-12 weeks after childbirth. Quantitative data was analyzed using descriptive statistics and t-test. Qualitative data was analyzed using Tutty, Rothery, & Grinnell's methodology. Result: The average score of the situational meaning in high the risk newborn mother was 53.57(possible score is between 0-96) and the average score of each item was 1.67. A Maternal transition process in the mother that has a positive situational meaning was conceptualized in three distinctive phases: confusion, accepting, and shaping phases. The Maternal transition process in the mother that has a negative situational meaning was also conceptualized in three distinctive phases: avoiding, conflicting, and accepting phases. Conclusion: It is necessary that the nurses provide high risk newborn mothers with individualized care considering both the situational meaning that is attributed to them and the maternal transition phase that they are faced with.

Korea, once called a nation of Oriental Courtesy has been tinged with the confusion of the view of value and the loss of humanity. Children and adolescents are seen as impolite. It has been accepted that urban children are more impolite than rural children. This study was performed to identify whether there are any difference in the courtesy between urban and rural children. Also the degree of relationship between the parents' courtesy education and the children's courtesy practice was analyzed. The results of the research are as follows : 1. Parents emphasized the education of the courtesy in school life, and neglected the education of the basic courtesy. Urban parents were more eager to educate the courtesy in school life than rural parents. 2. Children peformed the courtesy in school life best, and basic courtesy worst. Rural children practiced courtesy better than urban children. 3. There were significant relationships between parents' courtesy education and child's courtesy practice.

The legislative body of The People's Republic of China, the National People's Congress, enacted the first arbitration act in China's history on August 31st, 1994, which took effect on September 1, 1995. The problems revealed through a comparison of China's Arbitration Act with the UNCITRAL model arbitration law were studied as well as the enacting process, background, status and system, important contents, problems of Chaina's Arbitration Act, and the differences between the old arbitration regulations and the new arbitration act. These are all discussed in this paper. The Arbitration Act is the basic act ruling over china's arbitration system: it unified the previously confusing laws and regulations relevant to the arbitration system, and the act brings out fundamental changes in China's domestic arbitration to the level of international arbitration standards. It is possible to view this act as a cornerstone in China's arbitration system. But, as discussed in this paper, there are still a lot of problems with the new act and only a few of the merits which the UNCITRAL model arbitration law has. First, under China's Arbitration Act, parties enjoy autonomy to some degree, but the range of party autonomy, compared to that of the UNCITRAL model arbitration law, is too narrow. Second, because China's Arbitration Act didn't explicitly provide issues which can give rise to debate, a degree of confusion in its interpretation still remains. Third, China's Arbitration Act's treatment of some important principles was careless. Fourth, in some sections, China's Arbitration Act is less reasonable than the UNCITRAL model arbitration law. These problems must be resolved in order to develop China's arbitration system. The best way of resolving these problems for China is to adopt the UNCITRAL model arbitration law. But it is difficult to expect that China will accept this approach, because of the present arbitration circumstances in China. Although it is difficult to accept all the contents of the UNCITRAL model arbitration law, China's legislators and practitioners must consider the problems mentioned in this paper.

This study aims to investigate whether shortened vowel duration conditioned by a following voiceless stop induces phonetic reduction of vowel space in English, and whether the reduction appears more in the height dimension than in the backness dimension (Lindblom, 1963; Flemming, 2005). Fifteen native speakers of American English read minimal pairs containing ten American English vowels in [bVd] and [bVt] syllables in a carrier phrase. All the subjects produced shorter vowels in the voiceless than in the voiced context. However, a reduction in vowel space and a raising of low vowels due to the shortened vowel duration were generally not found. To the contrary, the speakers tended to exhibit even more lowering of low vowels in the voiceless context, and vowel space was more commonly compressed in the backness dimension than in the height dimension. Many speakers, in particular, demonstrated fronting of the high back vowel [u] in the voiceless context. It was interpreted that due to a relatively large number of English vowels in the narrower low vowel space, the raising of low vowels may give rise to confusion in vowel contrasts, and therefore the degree of phonetic vowel reduction is restricted in that region. On the other hand, the high vowel region, being relatively spacious in English, allows a certain degree of phonetic vowel reduction in the F2 dimension. It is possible that heavy requirements for maintaining vowel contrasts may cause speakers to overachieve vowel target values, especially when faced with vowels which are difficult to distinguish due to shortened vowel duration, leading to an over-lowering of the low vowels.
