This paper is concerned with a simultaneous design of TSK (Takagi-Sugeno-Kang)-linguistic fuzzy models with uncertain model output and the computationally efficient representation. For this purpose, we use the fundamental idea of linguistic models introduced by Pedrycz and develop their comprehensive design framework. The design process consists of several main phases such as (a) the automatic generation of the linguistic contexts by probabilistic distribution using CDF (conditional density function) and PDF (probability density function) (b) performing context-based fuzzy clustering preserving homogeneity based on the concept of fuzzy granulation (c) augment of bias term to compensate bias error (d) combination of TSK and linguistic context in the consequent part. Finally, we contrast the performance of the enhanced models with other fuzzy models for automobile MPG predication data and coagulant dosing process in a water purification plant.

This paper argues that Koguryo historically belonged to Korea based on the linguistic homogeneity among Koguryo, Sinra, and Paekche. The language of Koguryo shows the following four distinct properties from Chinese. First, Koguryo, Sinra, and Kara share a dual structure of national birth myths, and the directional vocabulary found in the countries also shows the evidence that the Korean people moved from North to South. Chinese, on the other hand, has no indication of these facts. Second, the place names in Koguryo shared the same properties with those of the countries in the Korean Peninsula at the same period, but were different from those of China. It is also noticeable that the national name of Korea, adopted from the national name of Koruryo, was announced to the world and that Korea has been acknowledged as our national name since then. The legitimate lineage of Koguryo > Parhay > Hu-Koguryo > Korea proves that Koguryo belonged to Korea historically, Third, the names of kings were very similar among the Three Kingdoms, but distinct from those of China. The names of kings were created on the basis of the sun as well as nature and human functions or activities like nuri (world), Piryu (originated from the name of a river), onjo (all over world), Chumong Hwar-bo (a person who is good at shooting), Paem-bo (a baby crawling like a snake), K\ulcornerchir-bo, Isa-bo, etc. This is a common characteristic among the Three Kingdoms, but clearly different from China. Fourth, the governmental names were very similar among the Three Kingdoms, but distinct from Chinese ones. These linguistic properties shared among the Koguryo, Packche, and Sinra are never accidental, but provide reliable evidence that the countries were founded by the Korean people. Koguryo, therefore, belonged to Korea historically.

본 논문은 수치적인 입출력데이터로부터 언어적인 규칙을 생성시키기 위한 체계적인 접근방법으로써 정보입자(information granules)에 근거한 언어적인 모델(LM: Linguistic Model)을 발전시킨다. Pedrycz에 의해 소개된 언어적인 모델은 컨텍스트 기반 퍼지 클러스터링(CFC: Context-based Fuzzy Clustering)으로부터 얻어지는 퍼지 정보입자에 의해 수행되어지며, 이는 입력과 출력공간과 연관된 클러스터 된 데이터들의 동질성을 보존하도록 클러스터를 추정한다. 언어적인 모델의 효능성은 이전 연구에서 이미 증명되었음에도 불구하고 성능 측면에서 개선시킬 필요성이 있다. 따라서, 본 논문에서는 기존 언어적인 모델의 근사화와 일반화 성능을 모두 향상시키기 위해 언어적인 컨텍스트의 자동적인 생성, 바이어스항의 추가, 결론부 파라미터의 변형된 구조를 통해 이루어진다. 실험결과는 자동차 연료소비량 예측문제와 보스턴 housing 데이터를 통해 제안된 방법이 언어적인 모델뿐만 아니라 기존 방법들보다 우수함을 증명한다.

It is widely known that language functions in our brains are lateralized to the left hemisphere and spatial recognition functions are lateralized to the right hemisphere. It is also known that handedness is closely related to the lateralization of brain functions. However, at what point in the brain‘s development the lateralization of brain functions takesplace is still disputed. This study sought to find differences in linguistic and spatial abilities between left-handed and right-handed children, and provide objective data on the relationship between the handedness and the brain lateralization. 19 left-handed children and 20 right-handed children aged 5 were chosen through questionnaire for this study and the K-WPPSI simple intelligence test was used to check the homogeneity of two groups. The results showed that the differences inlinguistic and spatial ability between left and right-handed children were not statistically significant.

음소 질의어 집합은 문맥 속에서 비슷한 조음 효과를 보이는 음소들을 분류해 놓은 것으로서, 음성 인식 시스템 학습 시 결정트리를 기반으로 HMM (hidden Markov model)의 상태들을 클러스터링할 때 사용된다. 현재까지의 음소 질의어 집합은 대부분 음성학자나 언어학자들에 의해 수작업으로 제시되어 왔는데, 이러한 지식 기반음소 질의어들은 언어 또는 유사음소 단위 (PLU: phone like unit)에 종속될 뿐 아니라 생성된 클러스터 내의 동질성을 저하시킬 수 있다는 단점이 있다. 본 논문에서는 이와 같은 문제점들을 해결하기 위해 음성 데이터를 사용하여 측정한 음소들 사이의 유사도를 기반으로 언어나 유사음소단위에 상관없이 자동으로 음소 질의어 집합을 생성하는 알고리즘을 제안한다. 실험결과, 제안한 방법으로 생성된 음소 질의어들을 사용한 인식기의 에러율이 약 14.3%감소하여 데이터 기반의 음소 질의어 집합이 상태 클러스터링에 효율적임을 관측하였다.

다문화 교육의 실천은 세계 여러 나라마다 다문화 사회 형성의 특징에 따라 다양하게 전개되고 있는 가운데, 최근 우리나라는 다문화 사회로의 변화에 대해 여러 분야에서 다문화 교육의 필요성이 제기되고 있는 있다. 본 연구에서는 새터민에 대한 고정관념과 사회적 친밀감의 정도가 북한에 대한 지식과 어떤 관련성이 있는지 살펴보았다. 새터민은 세계 여러 지역에서 이주해 온 이주자들처럼 한국사회에 적응해야하는 상황이면서, 언어적, 민족적 동질성을 가진 특수성을 가진다. 같은 민족이면서 다른 문화속에서 살아왔기 때문에 새터민과 남한 사람사이에는 문화적 이질감이 존재하고 있는데 새터민의 문화적 다양성을 인정하고 수용할 수 있는 태도를 갖도록 하는 것은 다문화적 감수성을 함양의 한 축이라고 할 수 있다. 새터민의 탈북양상이 최근 가족단위의 이주가 증가하면서, 학령기 아동의 한국사회 적응은 관련 당사자 모두의 과제인 가운데, 본 연구는 학교현장에서 중학생들이 새터민 학생들을 바라보는 시각에 주목하게 되었다. 본 연구에서 북한에 대한 지식을 범주화하여 교과지식, 북한상식, 시사이슈로 나누었으며 각각의 설명력 분석 결과, 북한에 대한 지식은 새터민에 대한 태도에 영향을 주고 있었다. 2007년 개정 교육과정의 적용에 따라 북한에 대한 교육 내용이 변화되는 상황에서 본 연구 결과는 지리교육 내용을 구성에 시사점을 가지며, 다문화교육 실천에 교과의 내용지식의 활용 가능성을 밝혔다는데 연구의 의의를 두고자 한다.

In the age of global communication, more human exchange is extended at the grass-roots level. In the old days, language policy and language planning was based on one nation-state with one language. But high waves of globalizaiton have allowed extended human flow of exchange beyond one's national border on a daily basis. Under such circumstances, homogeneity in Japan may not allow Japanese to speak and communicate only in Japanese and only with Japanese people. In Japan, an advisory report was made to the Ministry of Education in June 1996 about what education should be like in the 21st century. In this report, an introduction of English at public elementary schools was for the first time made. A basic policy of English instruction at the elementary school level was revealed. With this concept, English instruction is not required at the elementary school level but each school has their own choice of introducing English as their curriculum starting April 2002. As Baker, Colin (1996) indicates the age of three as being the threshold diving a child becoming bilingual naturally or by formal instruction. Threre is a movement towards making second language acquisition more naturalistic in an educational setting, developing communicative competence in a more or less formal way. From the lesson of the Canadian immersion success, Genesee (1987) stresses the importance of early language instruction. It is clear that from a psycho-linguistic perspective, most children acquire basic communication skills in their first language apparently effortlessly and without systematic and formal instruction during the first six or seven years of life. This innate capacity diminishes with age, thereby making language learning increasingly difficult. The author, being a returnee, experienced considerable difficulty acquiring L2, and especially achieving native-like competence. There will be many hurdles to conquer until Japanese students are able to reach at least a communicative level in English. It has been mentioned that English is not taught to clear the college entrance examination, but to communicate. However, Japanese college entrance examination still makes students focus more on the grammar-translation method. This is expected to shift to a more communication stressed approach. Japan does not have to aim at becoming an official bilingual country, but at least communicative English should be taught at every level in school Mito College is a small two-year co-ed college in Japan. Students at Mito College are basically notgood at English. It has only one department for business and economics, and English is required for all freshmen. It is necessary for me to make my classes enjoyable and attractive so that students can at least get motivated to learn English. My major target is communicative English so that students may be prepared to use English in various business settings. As an experiment to introduce more communicative English, the author has made the following syllabus design. This program aims at training students speak and enjoy English. 90-minute class (only 190-minute session per week is most common in Japanese colleges) is divided into two: The first half is to train students orally using Graded Direct Method. The latter half uses different materials each time so that students can learn and enjoy English culture and language simultaneously. There are no quizes or examinations in my one-academic year program. However, all students are required to make an original English poem by the end of the spring semester. 2-6 students work together in a group on one poem. Students coming to Mito College, Japan have one of the lowest English levels in all of Japan. However, an attached example of one poem made by a group shows that students can improve their creativity as long as they are kept encouraged. At the end of the fall semester, all students are then required individually to make a 3-minute original English speech. An example of that speech contest will be presented at the Convention in Seoul.
