A complex object model is one of the value based data model which extends the existing relational data model for supporting complex structured data. This paper studies a method for designing algebra for the complex object model. For this some others' algebra supporting complex objects are compared and analysed in terms of the applicability of a algebraic optimization strategics. The complex object algebra is designed, based on four principles, simple and clear definitions, no restriction on input data, single specification system. The central nature of this paper is to keep the basis of algebraic optimization method through simplicity, safety and the applicability of algebraic optimization strategy. Finally, it shown that the designed algebra has the equivalent or enhanced expressability with other's algebra.

우리 모두 소리의 표현력이 뛰어난 한글의 우수성은 너무나 잘 알고 있으며, 한글의 세계화를 외치고 있다. 그러나 그런 일을 해야할 국립국어원 등 국가기관은 외국어 표기법을 만들지 않고 있다. 외래어표기법으로 충분하다고 생각하고 있는 것이다. 외래어표기법은 현재의 한글을 유지하면서 외국어를 한글 단어로 만들 때 어떻게 만드느냐를 규정한 것이다. 한글세계화에 필요한 외국어 표기법은 한글로 외국어를 잘 표현함으로써 한글을 외국에 퍼트리는 것이 목표이다. 따라서 외국인이 쓰기에 편리해야하고 외국어 발음 왜곡을 최소화 하면서 잘 표현해 내기엔 현재 한글로는 부족한 면이 있음으로 표현력이 확장된 한글을 만들어야한다. 물론 확장된 한글이 현재의 한글과 동떨어지면 안될 것이다. 많은 분들이 여러 아이디어로 제안을 해 왔지만 대부분 자음을 추가하는 데에 집중되어 있다. 확장한글에서 다루어야할 것은 1) 추가되는 자음과 모음 2) 한글에 없는 성조나 강약 및 장단 등에 관한 규정 추가 등이면 된다고 생각하고 있다. 그러나 한글의 큰 특성인 음절이 외국어 표현 때에 왜곡되는 현상이 있는데, 어떻게 외국어와 한글의 음절개념을 일치시킬 수 있을지에 대해 관심을 가지고 방안을 제안하고자 한다. 그 방안으로는 1) 합용병서와 2) 풀어쓰기 활용법이 가능하나, 필자는 중간선으로 3) 촉진자 표기법을 제안한다. 또한, 크기조절법에 대응해 음절인 글자 위에 점을 표기하는 음절점표기법도 제안한다.

The purpose of this research was to examine the relationship of mother's emotional expressiveness, parenting self-efficacy, verbal control style and children's peer interaction, ability to solve interpersonal problem in an attempt to help improve mother's practical parenting style for promoting children's peer interaction and ability to solve interpersonal problem. The subject of this research were four to five year-old 212 children from five day care center in J city and their teachers. Teachers were tested by questionnaires and children were interviewed. There were the results of this research. There were significant positive correlation among mother's positive emotional expressiveness, positive peer interaction and ability to solve interpersonal problem. There were significant positive correlation among negative emotional expressiveness, negative peer interaction and ability to solve interpersonal problem. There were significant positive correlation between parenting self-efficacy and positive peer interaction. There were significant positive correlation among imperative verbal control pattern and negative peer interaction and ability to solve interpersonal problem. There were significant positive correlation among hierarchical verbal control pattern and negative peer interaction and ability to solve interpersonal problem. There were significant positive correlation among humanitarian verbal control pattern and positive peer interaction and ability to solve interpersonal problem. There were significant negative correlation between parenting self-efficacy and negative peer interaction. There were significant negative correlation between imperative verbal control pattern and positive peer interaction.

Objectives : This study was intended to compare coping style, family support, and parenting behavior between adolescent groups with different levels of perceived stress. Methods : A total of 795 high school students participated in this study. First, they were tested on the Perceived Stress Scale and then were separated into two groups depending on the level of perceived stress. Both groups completed the Scale for the Coping Style, the Family Environment Scale (relationship subscale) and Parenting Behavior Inventory. Results : The high stress group had significantly higher scores on all their coping scores than the low stress group. Also, the high stress group had significantly higher family conflict scores, lower family cohesiveness scores and lower expression scores than the low stress group. The high stress group experienced negative parenting behavior from both parents more often than the low stress group. In the adolescents with low family cohesiveness and expression, the use of active behavioral coping was decreased, if the higher stressful events occurred. The use of avoidant coping by these adolescents increased when there were higher levels of stress in their environment. Conclusion : Low family support directly reduced the usage of active behavioral coping and increased the use of avoidant coping strategy through the mediation of high stress condition.

Objective : The authors investigated family environemtn of ADHD referred to child psychiatric clinics. Method : Seventy two patients were grouped into pure ADHD and comorbid ADHD. Patient's lither and mother conducted the Korean Form of the Family Environment Scale(K-FES). And then, scores were compared with that of 77 normal controls. Results : Among subscales of K-FES, expressiveness, achievement orientation and organization were scored significantly lower in ADHD mothers' reporting than ADHD fathers' And only organization subscale was scored significantly lower in ADHD fathers' reporting than controls' In post hoc comparison, subscales of expressiveness, moral-religious emphasis and organization were significantly lower in mothers' reporting of pure ADHD and comorbid ADHD than of controls, and only organization subscale was significantly lower in fathers' reporting of comorbid ADHD than of controls. Conclusion : Parents of ADHD patients agreed that their families were not well organized, and each perceived somewhat differently on the family environment. Further study is needed to eludicate whether specific family environment causes ADHD or is caused by behavior of ADITD patients.

"The art challenges the technology, and the technology inspires the art." By this word John Lasseter expressed Pixar animations main soul of story. Media technology has a close relation with the animation. As media developed more and more, an animation has been widen a lot and have given new visions to the audiences. We can see such this figure from the history of the Disney animation. They had tried to make all the kind of animations such a silent animation, planetary animation, black and white animation and the multi colored animation. Lately Disney had made animation that has traditional style. But the method of making traditional animation stable side story's holdup the audience. So Disney animation decided to change this method. For the result of Disney animation studio effort Frozen had produced after a computer graphics work following Rapunzel. What was the reason for entertain well of Frozen? Not only changing the method of producing traditional to computer graphic is could not make entertain well. We can see from the Frozen concordance of the original idea and modern scenario, OST the perfection of computer graphics work. In this paper work Disney animation has worked from the silent animation to computer graphic works result of "The Frozen". For the contribution of technology development makes able to analyze animations expression and relation. There is a lot shots that hard to analyze in the Frozen. But I will study it with the method named "Expansion in space" to making main analyzing expressive extension that appears on the scene.

본 논문에서는 기존의 항만물류 EDI가 가진 문제점을 해결하기 위한 방안으로 제시된 XML/EDI 에 대해 살펴보고 항만 물류에 XML/EDI를 적용하기 위해 기존의 EDI 메시지를 XML Schema 로 변환하는 기법을 소개한다. XML 문서의 논리적 구조를 표현하는 방법은 크게 DTD(Document Type Definition) 와 XML Schema 의두 가지 방식이 있으며,k XML Schema 는 기존의 DTD 에 비해 다양한 데이터 타입의 지원, namespace 지원, open-ended 데이터 모델의 지원등 여러 장점이 있기 때문에 항만 EDI 메시지를 XML Schema 로 변환하면 DTD 로 변환하는 것에 비해 높은 표현력과 다양한 부가적인 처리를 지원할 수 있다.

이진 출력 기기에서 연속 계조의 영상을 받아들여 이진값으로 출력하는 이진화 알고리즘 중한 예로 마스킹(masking) 방법이 있으며, 마스크 방식의 단점을 보완하였다. 동일한 마스크의 반복적인 사용으로 인하여 영상의 부분적인 특성을 잘 표현해 주지 못하는 마스크들의 단정을 보완하기 위해서 국부 적응 임계값과 테이블 방식의 적응 파라메타를 제안하였으며, 결과적으로 시각적으로 중요한 경계성분을 강조와 국부 처리시 계조 표현력이 부족한 배경영역도 충분히 표현할 수 있었다.

XML은 웹에서 데이터 교환을 위한 마크업 언어로 반-구조화된 정보나 구조화된 정보를 교환하고 저장할 수 있으며, 표준언어로 채택되어 가고 있고, 강력한 표현력을 가지고 있기 때문에 다양한 애플리케이션을 가능하게 한다. 문서와 객체가 구조화 될 수 있는 방법을 제공하는 XML은 계층적 구조로 이루어진다. ORDB에서는 스키마 객체들이 계층적 구조로 구성되어 하나의 큰 객체를 이룬다. XML과 ORDB 사이에 단순한 XML 문서는 직접 변환이 가능하나 복잡한 XML 문서를 다룰 때는 객체 기반 변환 방법으로 처리되어야 한다. 따라서 본 논문에서는 XML DTD를 객체로 변환하고 변환된 객체를 ORDB 스키마로 변환하는 방법에 대하여 연구하였다.
