톨레미II는 내장형 시스템과 같이 이질적 성질을 가진 병렬 시스템을 모델링하고 디자인 할 수 있는 환경을 지원해준다. 톨레미II는 여러 개의 도메인을 가지고 있다. 도메인은 각 시스템의 구성 요소들간의 통신 방법을 결정하는 물리적인 규칙이다. 톨레미II에는 PetriNet, Timed Multitasking, SR 등 11개의 도메인이 존재한다. 시스템의 구성요소들은 그 특성에 맞는 도메인을 사용하여 명세되어질 수 있다. 톨레미II는 특히 정형적 도메인으로 프로세스 알제브라 언어의 일종인 CSP를 가지고 있다. 그러나 CCS는 도메인으로 구현되지 않았다. CCS는 프로세스 알제브라의 일종으로서 정형적으로 병렬시스템을 명세하고 검증할 수 있는 언어이다. 따라서 본 논문에서는 CCS도메인을 구현함으로써 톨레미II를 사용하는 개발자가 톨레미II에서 사용하고 있는 동일한 모델링 패턴을 사용하면서 CCS의 정형적 의미론을 바탕으로 하여 시스템 명세를 할 수 있게 하였다. 이것은 톨레미II의 도메인의 다양성을 가지고 옴으로써 톨레미II의 표현력과 가용력을 높였다. 본 논문에서는 톨레미II에 구현된 CCS 도메인의 구조와 구현 방법을 설명하겠다. PtolemyII is an environment that supports heterogeneous modeling and design of concurrent systems such as embedded system. PtolemyII has several Domains which are physical rules to determine the way of communicating between components. PtolemyII has 11 domains such as PetriNet, Timed Multitasking, SR etc. Components of System can be specified using appropriate domains for their properties. Communicating Sequential Processes(CSP) is implemented as formally designed CSP domain, in PtolemyII. But CCS didn't be implemented as a domain. It is a kind of Process Algebra language which can be used for specifying and verifying concurrent systems formally. Thus, in this paper we implemented CCS domain. And that permitted developers using PtolemyII to use the same modeling pattern used in PtolemyII and to make system specifications in the base of the formal semantics of CCS. This caused the diversity of PtolemyII domains and the power of expression was improved. This paper will explain the structure of CCS domain implemented in PtolemyII and the way of implementing it.

아동과 청소년의 친구관계 발달에 관한 연구

황혜정(Hye Jung Hwang) 한국아동학회 2002 아동학회지 Vol.23 No.3

This study examined the developmental characteristics of friends and disliked peers in 169 children and adolescents, including 44 preschool children, 43 primary school, 42 middle school, and 40 university students. Their descriptions of 2 same gender friends and 2 disliked same gender peers were categorized with an 81 category coding system. Comparisons across age and sex were made by a cross-tabulation test. Results showed that the reported characteristics of friends and disliked peers varied by age, but there was no sex difference. That is, younger children liked their friends because they played together, their friends were generous and attractive, but older children liked friends because they had some similarity, were reliable allies, caring and concerned. Younger children`s disliked peers were aversive, aggressive and hyperactive while older children`s disliked peers were dissimilar and snobbish.

황혜정(Hye Jung Hwang) 한국아동학회 1994 아동학회지 Vol.15 No.2

This study was designed to examine the effects of family structure (nuclear, extended family) on children`s behavioral and emotional problems. The subjects of this study were 650 primary school children aged 8 to 13 living in Seoul and Incheon (324 from nuclear and 326 from extended families). The Children`s Behaviour Questionnaire (CBQ: Rutter, 1970) and a questionnaire containing demographic questions and some additional questions were used for instruments. For the analyses, frequencies, descriptives, chi-square, factor analysis, and t-test were used. The results were analysed and explained in their cut-off points, prevalences, differences and factor structures. The cut-off score obtained in this study was 18, and the prevalences with this cut-off score were 6.3% in total subjects, 8.0% in nuclear families, and 4.6% in extended families. The children from extended families showed less behavioral and emotional problems, especially antisocial behaviours, compared with those from nuclear families, and this difference was significant (p<.05). The factor structures of the CBQ were `antisocial`, `neurotic`, `mannerism` and `speech` in total subjects, and, in the case of nuclear families, the factor structures were same as in total subjects, but, in the case of extended families, the `emotional anxiety` factor was included instead of the `speech` factor.

황혜정(Hwang Hye-Jung),정인희(Jung In-hee) 한국열린유아교육학회 2009 열린유아교육연구 Vol.14 No.5

본 연구는 국내외 기질에 관련된 연구를 고찰한 후 우리나라 만3?5세 유아의 발달단계에 맞는 일반적으로 수용 가능한 기질 측정도구를 개발하는 것을 목적으로 하였다. 문항의 작성을 위해 문헌연구와 부모와의 심층면접을 통하여 유아기질을 설명하는 105문항을 작성하였으며, 기질 평정척도의 적용 대상 연령의 모호함과 평정에 오류가 있는 문항, 사회?문화적 차이에 따라 기질의 구인을 찾기 어려운 20문항을 제거하여 총85문항을 예비문항으로 선정하였다. 그리고 본 검사를 통하여 문항을 확정하였다. 본 연구에서 개발된 부모용 유아 기질 평정척도는 총36문항이며, 6개 하위요인(적응성, 활동성, 지속성, 전환성 반응성, 규칙성)으로 구성되었다. 개발된 도구의 타당도, 신뢰도, 하위영역 간 상관계수들은 비교적 양호하였으므로 유아의 기질을 측정하기 위한 도구로서 타당하다고 볼 수 있다. This study aims to develop a generally acceptable measure of young children's temperament that is appropriate for the development stage of young children aged 3-5 years in Korea, Through literature reviews and in-depth interviews with parents, 105 items explaining young children's temperament were constituted. Among them, 20 items which were too obscure to apply to the temperament rating scale, wrongly evaluated, and too difficult to understand the concepts and meanings of temperament, and dependent on social and cultural difference were removed. Total of 85 items were selected as preliminary items. Then, the question items were completed through the test. The temperament rating scale of 36 items developed in this study was composed of 6 factors: adaptability, activity, durability, convertibility, responsiveness, and regularity. And its validity, reliability and correlation coefficients were relatively good, so that it could be explained that it had validity as a test to measure young children's temperament.
