The Vietnamese language has a specific property related to the zero in the name-number system. This study was conducted to examine the impact of linguistic differences and of the zero's position in a number on a transcoding task (verbal number into Arabic number). Vietnamese children and French-speaking Belgian children, from grades 3 to 6, participated in the study. The success rate and the type of errors they made varied, depending on their grade and language. At Grade 4, Vietnamese children showed performances equivalent to Grade 6 Belgian children. Our results confirmed the support provided by language to the understanding and performances in a transcoding task. Results also showed that a syntactic zero is easier to manipulate than a lexical zero for Vietnamese children. The relative influence of language and the source of errors are discussed.

This paper compares a cross-cultural and gender differences and similarities about consumer ethical perceptions and behaviors, and ethical ideologies between Korean and the US college students. It also examines the relationships between consumers' ethical perceptions and behaviors, and the relationships between consumer ethics and ethical ideologies. This research provides some evidence that supports the premise that consumer ethics is influenced to an extent by consumers' nationality and gender. The differences are not universal, however, and could perhaps be described as situational. The American college consumers were found to be more idealistic and relativistic than the Korean college consumers. But the differences were minor The American male college consumers were found to be more idealistic than the American female college consumers. The ethical consumer groups were found to be more idealistic and less relativistic than were the unethical consumer groups. Perceptions were positively related to behaviors in the consumer ethics. But the magnitude of impacts is different between the nations and in the dimensions of consumer ethics.

Interior permanent magnet synchronous motor is widening its application compared to other AC machines because of magnetic and reluctance torque. Despite of the advantages, improving control performance with parameter nonlinearity consideration is crucial during the field weakening control. This paper shows a maximum power control method at the field weakening region that considers d, q inductance's nonlinearity due to magnetic saturation and d, q mutual inductance. To verify the feasibility of control scheme, FEM simulations and experiments about comparison between linear and nonlinear maximum power control are carried out.

The purpose of this study was to investigate cross-cultural comparison of landscape preferences among Korean, Japanese and Western groups, and to get some clues to be used in judging this cultural influence. Moreover this study suggested fundamental data for design theory of modern landscape architecture. The results were as follows ; Natural factors including vegetation, water and rock, structural factors and spatial factors could be significant variables on Korean traditional landscape. The mean preference scores for both landscape element and landscape space were significantly different(p(0.01, p(0.05) with the Korean most perferred, the Western in the middle, and Japanese least. There were both differences and similarities in landscape preference among Korean, Japanese and Western groups.

In the current study, we present a new model for predicting width spread of a slab with a dog-bone shaped cross section during rolling in the roughing train of a hot strip mill. The approach is based on the extremum principle for a rigid plastic material and a three dimensional admissible velocity field. The upper bound theorem is used for calculating the width spread of the slab. The prediction accuracy of the proposed model is examined through comparison with the predictions from 3-D finite element (FE) process simulations.

This study investigates the difference of the cognitive approach of Korean and Chines of the space direction that modern Chinese space phrase 'N+shang'. For this, we defined the spatial meaning of the noun 'N' and space noun 'shang' then investigate the conditions when 'N+shang' means 'the substance interior direction' and 'the substance exterior direction'. Also via 'lou+shang', we conducted the survey to Korean and Chinese students in order to see the what kind of cognitive differences be shown when they approach and translate the space direction of 'N+shang' structure. As a result of the survey, we were able to find cultural difference of spatial approach of 'N+shang' between these two countries, Korean select the cognitive inference path; from the substance external direction to internal direction while Chinese select from internal to external.

This study reviews critical literatures regarding Asian cinema, focusing on studies of Japanese cinema, to show that Western scholarship on non-Western national cinemas have been divided into two approaches: traditionalism and modernism. It argues that such a division is not merely a critical tendency but indicative of the fact that a national cinema is an internally divided construct. To support the point, this study examines Chinese film studies conducted by Chinese film critics and the history of South Korean cinema during the 1970s and 80s. Then, it proposes the hegemony model to theorize the inner structure of national cinema. It finally suggests the possibility of comparative film study that the national cinema thesis may activate.

In Teaching Chinese as a Foreign Language, phoneme-based pronunciation teaching such as tone, consonants, vowels is the most common teaching methods. Based on main character of Chinese grammar: 'lack of morphological change' in a narrow sense, was proposed by Lv Shuxiang and Zhu Dexi, I designed 'Communicative oriented Chinese pronunciation teaching method'. This teaching method is composed of seven elements: one kind is the 'structural elements': phoneme, word, phrase, sentence; another kind is the 'functional elements': listening, speaking and translation. This pronunciation teaching method has four kinds of practice methods: 1) phoneme learning method; 2) word based pronunciation practice; 3) phrase based pronunciation practice; 4) sentence based pronunciation practice. When the teachers use these practice methods, they can use the dialogue and Korean-Chinese translation. In particular, when the teachers use 'phoneme learning method', they must use Korean and Chinese phonetic comparison results. When the teachers try to correct learner's errors, they must first consider the speech communication.

The aim of this study is to compare and analyze the similarities and differences in traditional perspective about women between Algery and Korea. Through this study, we found out following common denominators: sexual discrimination and denigration of women. Under the patriarchal system in Korea and Algery in the past, women were considered to be inferior to men and treated as men's possessions. The noteworthy feature is the perspective of mother. In both countries, the image of woman as a mother is regarded as the source of life and a central axis leading our society. It is very remarkable that we could find a lot of common ground despite that there are a lot of social, cultural and geometrical differences. Therefore, through this study, it is proved that the proverbs tell us the universality among people in the world regardless of culture and region.

섬유보강 콘크리트의 균열 후 인장 거동을 예측하기 위해서는 균열면에 걸쳐 있는 섬유의 개수를 산정하는 섬유분포계수를 합리적으로 예측하는 것이 필요하다. 이 논문에서는 원형단면에서의 섬유분포계수를 분석하기 위해, 콘크리트 압축강도, 단면 크기, 섬유 종류 및 섬유혼입률 등을 변수로 강섬유보강 콘크리트 공시체를 제작하였으며, 제작한 공시체들을 타설 방향에 수직인 방향으로 절단한 후, 절단된 원형 단면에서의 섬유 개수로부터 섬유분포계수를 측정하였다. 측정 결과, 섬유가 타설면에 평행하게 분포할 확률이 증가함에 따라 실제 원형단면에서의 섬유분포계수가 일반적으로 알려진 0.5보다 작은 것으로 나타났다. 또한, 단위 면적 당 섬유 개수가 증가할수록 섬유분포계수가 감소하는 것으로 나타났다. 이 논문에서는 원형단면에서의 섬유분포계수를 합리적으로 예측하기 위해 섬유가 분포할 수 있는 각을 기하학적으로 분석하고, 이로부터 상세 모델과 단순화한 식을 유도하였다. 제안된 모델과 실험에서 측정된 섬유분포계수를 비교한 결과, 제안된 모델이 실제 원형단면에서의 섬유분포계수를 잘 예측하는 것으로 나타났다. 이 연구로부터 확보된 실험 결과 및 제안 모델은 향후 원형단면을 지닌 섬유보강 콘크리트 기둥 부재 등의 구조적 거동 연구에 매우 유용할 것으로 사료된다.
