  • Developers can reuse not only class code but also wide range of knowledge on domain by reusing framework. Existing Object-Oriented Methodology and Catalysis Methodology were presented when redefining component in the course of redesigning framework. However, existing methodologies have weakness that entire process is waterfall mode or design of interface lays too much stress on implementation stage. So, this thesis will present Component-Oriented Methodology for the reuse of framework, and construct the environment for framework and domain development. That is, domain is analyzed by input of domain knowledge on real world to create software based on component, and hotspot is identified through analyzed information, and refactoring by putting additional information on users and developers. After that, I will create domain framework and application framework depending on domain. In this Component-Oriented Methodology, information is searched, understood and extracted or composite through component library storage internally. Then this information is classified into the information on component, and used as additional information in redesigning. With this, developer can obtain reusability, easiness and portability by constructing infrastructure environment that allows to register, update and delete component through Component Management System(CMS) under he development environment which can be easily applied to his own application using framework component, in this thesis, CoRBA(Common Object Request Broker Architecture) environment.

  • Recently XML (eXtensible Markup Language) is becoming the standard for exchanging the documents on the web. And as the amount of information is increasing because of the development of the technique in the Internet, semantic web is becoming to appear for more exact result of information retrieval than the existing one on the web. Ontology which is the basis of the semantic web provides the basic knowledge system to express a particular knowledge. So it can show the exact result of the information retrieval. Ontology defines the particular concepts and the relationships between the concepts about specific domain and it has the hierarchy similar to the taxonomy. In this paper, we propose the generation of semi-automatic ontology based on XML documents that are interesting to many researchers as the means of knowledge expression. To construct the ontology in a particular domain, we suggest the algorithm to determine the domain. So we determined that the domain of ontology is to extract the information of movie on the web. And we used the generalized association rules, one of data mining methods, to generate the ontology, using the tag and contents of XML documents. And XTM (XML Topic Maps), ISO Standard, is used to construct the ontology as an ontology language. The advantage of this method is that because we construct the ontology based on the terms frequently used documents related in the domain, it is useful to query and retrieve the related domain.

  • In order to assess the knowledge and learning needs. 72 patients with the first onset myocardial infarction were interviewed by the structured questionnaires during the period of September, 1999 to July, 2000. The results were as follows 1. As a whole. $57.9\%$ of patient had correct knowledge in relation to myocardial infarction. As for the knowledge score in terms of general characteristics, the patients who were in higher education and living with spouse were significantly higher point than those who were in lower education and living alone. 2. The mean scores of learning need of the subjects was 4.13 measured by Likert 5 point scale, No significant differences were shown in the score of learning need in terms of the general characteristics. As for the learning need according to domain, the subjects had higher leaning needs in the domain of diet, risk factors and activity and exercise. 3. There was no significant correlation between the learning need and the knowledge of myocardial infarction. The results of finding show that education program should be consider the general characteristics. the level of knowledge and learning needs of the myocardial infarction patients.

  • Purpose: This study was to investigate the effects of health education on health knowledge and health promoting behaviors in elementary school students. Methods: 17 sessions of health education were provided to the fifth graders in two elementary schools in Gyunggi Province and data were collected from 268 students. The data of 250 students who had responded both pretest and posttest were analyzed using SPSS program. Results: The scores of health knowledge for mental health, social health, sex and health were lower than other domain. The scores of knowledge for drug abuse/smoking and disease prevention/management were higher than other domain. Overall health knowledge was improved significantly from 0.60 at pretest to 0.81 at posttest (t=15.98, p<.001). The score of health promoting behaviors at post test was higher than score at pre test but this change was not significant (t=-0.91, p<.365). Conclusion: Health education had significant effects on health knowledge and we need to maintain and activate health education in elementary schools. Health education did not have significant effects on health promoting behaviors, we need to do further research for understanding why and how we improve health promoting behaviors.

  • 본 연구의 목적은 PISA 2015 결과와 비교하여 PISA 2018 과학 영역에서 성취수준 집단별로 과학적 소양 성취 특성을 알아보고, PISA 2018에서 PISA 2015보다 정답률이 특히 상승한 '인식론적' 지식에 대해 PISA 참여 학생들이 경험한 교육과정을 중심으로 비교 분석하는 것이다. PISA 2015와 PISA 2018 평균 정답률을 PISA 과학 영역 평가틀 차원별 하위영역별로 분석하였다. 특히, '역량' 차원에서 중집단과 하집단에서 '과학 탐구의 평가 및 설계' 정답률이 가장 낮았지만, PISA 2015과 비교하여 모든 성취집단에서 정답률이 상승하였다는 점에서 고무적이다. '지식' 차원에서 '생물계' 지식과 '인식론적' 지식에서 정답률이 낮았지만, PISA 2015와 비교하면 '인식론적' 지식에서 상집단과 중집단의 정답률이 상승하였다. PISA 2015에 비해 PISA 2018에서 정답률이 상승한 '인식론적' 지식과 관련하여 PISA에 참여한 학생들이 경험한 교육과정의 변화를 살펴보았다. 과학에 대한 이해 측면에서 2009 개정 교육과정에서는 '과학이란?' 단원과 과학 탐구 활동에서 모형에 대한 이해를 향상시킬 수 있도록 하였다. 과학 지식을 정당화하는 과정에 대한 이해 측면에서 2009 개정 교육 과정에서는 탐구 활동의 수는 증가하고 실험 결과에 기반한 과학적 설명을 강화하였으며 '과학과 인류 문명' 단원을 도입하여 학생들이 STS를 이해하는 것과 동시에 논변활동을 할 수 있도록 하였다. 본 연구를 통해 PISA 2015와 비교한 PISA 2018의 성취수준별 인지적 성취 결과를 알아보았고 우리나라의 과학과 교육과정 개정이 탐구 수업을 통한 인식론적 지식 함양 교육 측면에서 긍정적인 방향으로 나타났다는 것을 확인하였다.

  • The purpose of the study was to compare both the nursing care satisfaction and the image of nurses as experienced by home health care clients and hospitalized clients. For the descriptive survey study. data were collected from 69 home heath care clients and 342 in-patients in a university hospital. The tools used for the study were modified by Quality Patient Care Scale(Wandelt & Ager. 1974) and Image of Nurses (송인자, 1993). The data were analyzed using Pearson Correlation. Scheffe test. factor analysis. t-test. and ANOVA. The major findings were as follows: Regarding nursing care satisfaction, the mean score of total nursing care satisfaction in home health care clients was 3.28 out of 4.0. Among five domains, the domain with the highest score was the psychosocial domain, followed by the general. the professional. the physical. and the communication domain. The level of nursing care satisfaction was not significantly different according to demographic variables except for age: the age group of 41-60 showed the highest score (p<0.05). The mean score of total nursing care satisfaction in hospitalized clients was 2.95 out of 4.0. Among five domains, the domain with the highest score was the psychosocial domain, followed by the physical and the communication. the professional. and the general domain. The level of nursing care satisfaction was not significantly different according to demographic variables except age: the higher the age the higher the score (p<0.05). The levels of nursing care satisfaction in all five domains were significantly higher in home health care clients than in hospitalized clients(p=0.0005). Regarding image of nurses, the mean score of total image of nurses in home health care clients was 3.32 out of 4.0. Among four domains, the domain with the highest score was the sincerity domain, followed by the kindness. the spirit. and the knowledge and skill domain. The level of image of nurses was not significantly different according to demographic variables. The mean score of total image of nurses in hospitalized clients was 3.05 out of 4.0. Among four domains. the domain with the highest score was the sincerity domain, followed by the kindness, the knowledge and skill, and the spirit domain. The level of image of nurses was not significantly different according to demographic variables. The levels of image of nurses in all four domains were significantly higher in home health care clients than in hospitalized clients (p=0.001). Both the levels of nursing care satisfaction and image of nurses, part of an evaluation for quality of nursing care were significantly higher in home health care clients than in hospitalized clients. In light of the findings, we could consider that home health care nurses provided client-centered comprehensive nursing care. However, nurses need to have methods that more promote the social recognition of the image of nurses and nursing care services as well as professional knowledge and skills.

  • 이 논문에서 연구자는 중학생들의 수학 학습을 삼 년간에 걸쳐 관찰하면서 그들이 유리수 범위에서 형성한 개념적 지식과 절차적 지식 사이의 발달 관계에 대하여 조사하였다. 특히, 아래의 두 상황에서 학생들의 개념적 지식과 절차적 지식 사이의 불균형한 발달이 이후의 지식 발달에 어떤 영향을 미치는 지에 관하여 조사하였다: (a) 상대적으로 강한 개념적 지식과 약한 절차적 지식을 가진 경우; (b) 상대적으로 약한 개념적 지식과 강한 절차적 지식을 가진 경우. 연구 결과는 개념적 지식과 절차적지식이 균형적인 방식으로 (즉, 아주 근접하게 되풀이되거나 동시에) 발달될 때 가장 생산적이라는 것을 시사하며 또한 어느 한 가지 유형의 지식이 다른 유형의 지식보다 우위에 있다는 가정에 의문에 제시한다.

  • Existing methodologies and practical ontology development experiences have explored a broad spectrum of knowledge management challenges. Each has its own characteristics and evaluates only a subset of specific domain. However, there is still no one 'correct' way or methodology for developing ontologies. In this paper, we described a methodology for domain driven ontology development, covering the whole lifecycle from the formalization of domain to the evolution of ontologies.

  • The purpose of this study was to investigate effects of mental capacity and mental demand on problem solving. Two kinds of tests were used for this study. One was FIT 752 test which required general knowledge, the other was Ohm's law test which required domain specific knowledge. The items of each test had the same logical structure and content knowledge but had different sizes of mental demand. The results of the study were summarized as follows: As mental demand of the items increased, the success rates decreased. The analysis of the hierarchical relation among items was that items with large mental demand were higher than those with small demand or at least the same level. According to the results, mental of an item was a significant factor affecting solving the problem. Effect of mental capacity on problem solving was different according to the kind of required knowledge to solve. Mental capacity was a significant factor affecting solving the FIT 752 task which required general knowledge. On the contary, solving the task which required domain specific knowledge, the results were different depending on subjects' chunk size. The results of problem solving of the groups which had small chunk size were that mental capacity was appeared a significant factor. However, results of problem solving of groups which had large chunk size were that mental capacity was not.

  • The purpose of this study was to make valuable suggestions for improving environmental education(EE) teaching materials. For the purpose of this study, we analyzed four secondary school EE textbooks in the perspective of environmental literacy components. The findings of this study are as follows: (1) As a whole, the EE textbooks tend to focus the understanding environmental knowledge much more than environmental activities. (2) In 'main text' domain of EE textbooks, environmental information, including environmental issue knowledge, is much more focused than environmental attitudes and behavior, including socio-political and environmental issue knowledge. (3) In 'graphic data' domain, environmental information about environmental issue knowledge was most prevalent. (4) Most learning activities focus on 'issue skill' component, rather than 'attitude' and 'action' component. (5) The objectives of EE in the 7th national Curriculum were not explicitly embedded in textbooks and too much is inclined toward 'knowledge' and 'skill'. Accordingly, it is necessary to develop 'module-type' EE textbooks to enable integrative EE. Also, it is suggested to develop specific strategies for linking environmental knowledge and attitude/behavior.
