This study is to investigate the creative thinking style and it's leaning that normal students and scientifically gifted students use mainly at processing information. Right Brain vs Left Brain Creativity Test(R/LCT) and Brain Preference Indicator(BPI) is taken to investigate the creative thinking style of normal students(N=144) and scientifically gifted students(N=97). In the R/LCT, the normal students responded that they prefer to use right-brain thinking rather than left-brain thinking. But the scientifically gifted students prefer to left-brain thinking. The normal students showed most preference for Holistic Processing of right side brain and they did most avoiding for Verbal Processing of left side brain. The scientifically gifted students showed most preference for Logical Processing of left side brain. And they did most avoiding for Random Processing of right side brain. There was a meaningful difference between left side brain preference group and right side brain preference group on Sequential, Symbolic, Logical, Verbal, Random, Intuitive, Fantasy-oriented Processing of normal Students. But the scientifically gifted students showed a meaningful difference in right side brain processing mainly. In other word, all the scientifically gifted students took an lean processing in Logical, Symbolic, Linear Processing, etc. In sum, the scientifically gifted students are unequal in at processing information against the normal students. So it is required more appropriate teaching-learning method based on the creative thinking style and it's leaning for effective gifted education.

Today raises its head on the issue of interoperability caused by the complexity of the embedded software and the diverse development environment about SUGV(Small Unmanned Ground Vehicle). So, we propose to adopt the original MDA mechanism for this heterogeneous embedded development. To solve this problem, we apply for developing SUGV with MDA(Model Driven Architecture) using the original UML profile mechanism. Through this method, it can be semi-automatically transformed into TSM(Target specific model) after modeling TIM(Target Independent Model). Then we can also automatically generate the heterogeneous source codes. Therefore it will be reduced the development cycle and effort of the heterogeneous systems. We verify the benefits of our proposed approach and the reliability through analyzing the generated codes.

신호 교차로에서 포화차두시간에 영향을 미치는 영향인자는 도로조건, 교통조건, 환경조건으로 분류된다. 이러한 요인들의 복합적인 관계가 포화차두시간에 영향을 미친다. 현재 포화교통류율은 이상적인 조건일 때의 포화차두시간을 산출하고, 이를 이용해서 기본 포화교통류율을 구하고, 여기에 좌 우회전, 차로폭, 경사, 중차량 보정계수을 고려함으로써 특정 차로군의 포화교통류율을 산정하고 있다. 포화차두시간에 영향을 미치는 인자들 중에서 정량적으로 나타내기 어려운 인자 즉, 퍼지적 성격을 가진 인자들은 고려하지 않고 있다. 따라서 본 연구에서는 퍼지 근사추론 방법을 이용하여 정성적 인자의 영향을 고려한 모형을 구축하였다. 모형의 입력자료는 강우조건과 주변밝기의 정도, 중차량 구성비의 언어적 표현를 사용하였다. 이러한 변수들에 대하여 설문조사를 통해서 퍼지집합의 멤버쉽함수를 설정하였으며. 이에 기초하여 교차로에서 각 조건별로 포화차두시간을 관측하였다. 이러한 현장 관측치를 바탕으로 퍼지 제어규칙을 설정하고 모형을 구축하였다. 모형의 평가는 추론치와 실측치를 비교함으로써 이루어 졌으며, 결정계수인 $R^2$와 평균절대오차(MAE)와 평균제곱오차(MSE)를 사용하여 분석한 결과 본 모형의 설명력이 높은 것으로 평가되었다. 본 연구의 과정에서 강우에 의한 교통용량 감소는 중차량 구성비가 클수록 주변밝기의 정도가 나쁠수록 더욱 큰 것으로 나타났으며 그 감소율은 5.3%에서 21.8%에 이르는 넓은 범위의 값을 보였고. 주변밝기 정도에 따른 교통용량 감소는 4.7$\sim$7.5% 수준으로 나타났다.

A graphic control language using function block diagram approach is designed and implemented, applicable to real-time control for continuous process automation system. The procedure implementing the control language is composed of three parts, editor, compiler, and executer. The editor generates the control algorithm file, which contains function block information in the text form, by menu-driven method on the color graphic screen. The compiler translates the contents of the control algorithm file to machine codes and their related data. Then, the executer generates a task that makes the machine codes executed at every sampling period in the target processor. The validity of the concept in its design and implementaion is assured by on-line simulation in the multi-function controller designed for continuous process automation.

The role of memory is viewed as central to developing and maintaining flight situation awareness (SA). The present research examines constituent memory processes that underlie flight SA sensitivity as a function of pilot expertise. In Experiment 1, pilot memory for different forms (spatial or verbal) of cockpit situational information was tested immediately after presentation of the information (immediate recall) or after 30-s delay filled with an intervening task (delayed recall). In Experiment 2, pilot SA sensitivity was examined and correlated with memory measures obtained in Experiment 1. Results suggest that an expertise effect occurs in delayed recall but not in immediate recall and that memory representation of situational information required to develop high levels of SA sensitivity varies as a function of expertise. Theoretical accounts of results are discussed in the context of psychological theories of expertise.

The aim of this paper is to describe the linguistic differences of two Koreas with a special emphasis on the phonetic aspect of Seoul and Pyongyang speech. The sources of the North Korean speech material used in the study are 1) the Pyongyang radio and TV broadcasts, 2) interviews of north Korean defectors and 3) speech material of north Korean scholars collected by the writer in london, Warsaw, France and China between 1989 and 1994. The most noticeable phonetic differences of Seoul and Pyongyang speech are abstracted as follows: 1) The vowels /이/, /에/ and /애/ are higher and fronter in Pyongyang speech than in Seoul speech. 2) The vowels /우/ and /으/ of Pyongyang speech are somewhat fronter than the corresponding vowels of Seoul speech. 3) The Pyongyang vowels /으/ and if are produced with rounded lips compared to the corresponding Seoul vowels. 4) The Pyongyang vowel /h) is much lower in tongue position and at the same time somewhat fronter than the corresponding Seoul vowel. 5) The consonants /r ,i ,n / are pronounced in Pyongyang as alveolar affricates or something close to them whereas they are pronounced in Seoul as post-alveolar affricates. 6) Unlike in Seoul speech there is a very strong tendency in Pyongyang speech to reduce aspiration feature in consonant seouences such as /ㅂ+ㅎ/, /ㄷ+ㅎ/, /ㄱ+ㅎ/. 7) /ㄴ/ and /ㄹ/(flap) freely occur word-initially in Pyongyang speech whereas they are restricted in Seoul speech. 8) Unlike in Seoul speech the phonemic contrast of long and short vowels are generally not functional in Pyongyang speech. Thus the vowels pronounced long in Seoul speech are usually pronounced short in Pyongyang speech.

The explosive growth of the Web is providing end-users access to ever-increasing volumes of information. The resources of legacy systems and relational databases have also been made available to the Web browser, which has become an essential business tool. Recently, model management on the Internet/Web is also proposed with its conceptual design or prototypical system like DecisionNet and DSS Web. However, they are also suffering from the same symptoms as the Web, Although we can identify the elements of a page with HTML tags and (declare) the relationships among the various document elements, they are semantically opaque to computer systems and have no domain-specific meaning. However, HTML is not extensible, so developers are forced to invent convoluted, non-standard solutions for embedding and parsing data. Extensible Markup Language (XML) is a simplified subset of SGML that has many benefits for folks who want to improve structure, maintainability, searchability, presentation, and other aspects of their document management. This paper proposes a structured markup language for model representation and management on the Web as an XML application. The language is based on a conceptual modeling framework, Object-Oriented Structured Modeling (OOSM), which is an extension of the structured modeling.

For the purpose of better understanding of RAD children, comparisons were performed about the developmental and psychopathological characteristics between RAD and PDD children. Study subjects were the children between the ages 2 and 6. who visitied SNUCH Child and Adolescent Psychiatry OPD or treated in Day Treatment Center during May, 1989 and Sep., 1991, diagnosed by the child psychiatrist as RAD or PDD according to DSM-III-R diagnostic criteria. A total of 40 children were included in the study. 20 were RAD(18 boys, 2 girls). 20 were PDD(20 boys). PEP was performed to all study subjects, by the raters blind to psychiatric diagnosis of each. And analysis was done about the level of developmental functioning score and psychopathological scores between RAD and PDD children. The results are as follows 'There were retardation on the general developmental functioning in RAD children, and the severity of retardation were lined up as perceptual ability>imitation>gross motor>cogitive language>eye-hand coordination>fine motor. Characteristics of psychopathology in RAD children were lined up by severity as language>play>relationship>affection >sensory. Group differences of the two shows on PDD group rejection score was significantly higher on the perception item. while RAD was superior on the perception emerging response. Differences of the psychopathology between two groups were on such areas as ; Affection, which was significantly higher on 'Absent' in RAD, while significantly higher on 'severe' in PDD children. On the interest for the play and materials. sensory and language areas, RAD children were significantly higher ratings on 'Absent' than PDD children.
