  • 소프트웨어 제품들 사이의 공통된 개념과 서로 다른 개념들을 표현한 특성 모델과, 특정 제품에 포함될 특성들을 선택한 결과인 특성 구성은 소프트웨어 프러덕트 라인 개발 방법론에서 핵심 요소이다. 이들에 대한 정형적 시맨틱과 논리적 추론에 대한 연구가 진행 중이지만 시맨틱 웹 기술을 이용한 특성 모델 온톨로지 구축과 특성 구성 검증에 대한 연구는 아직 부족한 상황이다. 본 논문에서는 온톨로지와 시맨틱 웹 기술을 이용하여 특성 모델의 정형적 시맨틱을 정의하고 특성 구성을 검증하는 기법을 제안한다. 특성 모델과 특성 구성에 포함된 지식을 시맨틱 웹 표준 언어인 OWL(Web Ontology Language)로 표현하고 특성 구성을 검증하기 위한 규칙은 시맨틱 웹 규칙 언어인 SWRL(Semantic Web Rule Language)로 정의한다. 본 논문의 기법은, 특성 모델의 정형적 시맨틱을 제공하며 특성 구성 검증을 자동화할 뿐 만 아니라 SQWRL과 같은 다양한 시맨틱 웹 기술 적용을 가능하게 한다.

  • CBSD(Component-Based Software Development)는 이미 존재하는 소프트웨어 컴포턴트를 조립함으로써 시스템을 개발하는 방법이다. 컴포턴트를 이용하여 시스템을 개발하는것을 개발시간과 비용을 줄이고, 생산성을 향상시키는 등 여러 가지 장점을 가진다. 그러나 여러 벤더에 의해 개발된 컴포넌트를 조립하는 것은 쉬운 일이 아니다. 이를 위해 컴포넌트가 어떤 문맥에서 사용되는지 이해하는것이 필요하며, 이 문맥은 아키텍쳐에 의해 결정된다. 따라서 컴포넌트 기반의 어플리케이션 개발은 아키텍쳐를 기반으로 하였을 때 가능하다. 또한 컴포넌트 기반 어플리케이션 개발을 위해서는 도메인 개념이 필수적이다 컴포넌트의 재상용을 높이기 위해서 관련된 시스템의 집합인 도메인에서 컴포넌트를 개발해야 한다. 본 논문에서는 컴포넌트 기반 어플리케이션 개발을 지원하는 도메인 아키텍쳐 개발방법을 제안한다. 도메인 아키텍쳐는 도메인 분석 및 설계과정에서 생성되는 것으로 컴포넌트와 그들간의 관계를 표현한다. 도메인 아키덱쳐를 이용하여 컴포넌트를 개발함으로써 재사용성이 높은 컴포넌트를 효율적으로 개발할수 있을 뿐만 아니라, 어플리케이션 개발 시 도메인에서 제공하는 정보를 이용하여 쉽게 어플리케이션을 개발할수 있다.

  • 수학사의 교육적 연구를 비판적으로 분석해 보고, 교사 및 교사교육자를 대상으로 하여 실시한 설문조사와 면담결과를 통해 수학사를 교육적으로 활용하고자 할 때 해결되어야 할 문제점을 찾아보고자 하였다. 수학학습에 대한 흥미와 학습동기 유발을 넘어서 수학사를 통해 수학적 개념의 진정한 의미와 그 핵심적인 관점의 이해를 심화시킨다는 측면에서 볼 때 수학사의 교육적 이용에 대한 연구 결과와 교사의 수학사에 대한 인식에는 만족스럽지 못한 측면이 있으며, 교사 교육기관에서의 수학사 교육은 수학사의 개관에 그치고 있어 충분하지 못하며, 학교수학에 대한 역사 발생적 자료의 개발, 나아가 역사 발생적 교재구성에 대한 연구가 절실히 요구된다.

  • 본 연구에서는 교육용 게임의 본질을 분석하고자, 기호학적 분석 방법을 도입하여 연구를 수행하였다. 교육용 게임에서 기호가 어떤 방식으로 나타나는지를 분석하였으며, 교육에 대한 개념을 기호와 기호작용이라는 관점으로 설명한 퍼스의 기호학을 이용하여 교육적으로 활용하는 게임인 롤러코스터 타이쿤2를 분석하였다. 분석결과 표상체, 대상체, 해석체의 기호와 함께, 일차성, 이차성, 삼차성의 기호를 모두 가지고 있었다. 특히 롤러코스터 타이쿤2에서는 2차성과 3차성의 기호가 많은 부분을 차지하는 것으로 분석되었다. 2차성의 기호는 논리적이고 창의적인 사고를 하는데 도움을 주는 기호이며 3차성 기호는 학습자의 창의력 신장에 도움을 주는 기호이다. 이 기호가 교육용 게임에서 많이 등장하는 것은 논리적인 전략을 세워서 문제를 해결해야하는 상황이 중심이 되는 것으로 해석할 수 있다.

  • Objectives : ShangHanLun is a clinical guideline, and its core is in the part of Six-meridian Diseases. In recent philological sutdies, independent textual analysis of Shanghanlun is essential to define the scope of research. Methods : By the textual study, I defined the Shanghanlun clinic model. And I researched about medical range of Shanghanlun, and relations between Shanghanlun and JinGuiYaoLue, and between Shanghanlun and Huangdineijing. Results : In six topic sentences, the word '-之爲' means 'a process'. In provisions following topic sentences, the word '者' means 'a person'. So Shanghanlun is describing processing factors of Six-meridian Diseases and related human changes with clinical therapy. In the philological studies, meaning of '傷寒' was possibly just the 3rd provision of the greater yang disease part. Practically Shanghanlun's study range is over the concept of Cold damage today. Additionally Jinguiyaolue deals diseases, but Shanghanlun deals human. Gangpyeong-Shanghanlun's phrases can be separated into five part, and oldest part is independent of Huangdineijing. Conclusions : So we need to set a new and independent clinic model of Shanghanlun to verify it. The Shanghanlun's clinic model has a 3 steps. 1st step is to find 6 type defined symptoms, which act as processing factors of Six-meridian Diseases. 2nd step is to confirm a human changes after a Disease appeared. 3rd step is to treat a patient as a provision suggests. Philologically Shanghanlun's clinic range is not limited by the word '傷寒'. And many concepts in Shanghanlun should be independent of Huangdineijing.

  • 구조물의 수명관리는 일반적으로 불확실성의 효율적 고려를 위해 신뢰성 이론을 적용한다. 전체 구조시스템의 신뢰성 평가는 구조요소의 신뢰성 평가와 구조시스템의 모델링을 통해 이루어진다. 구조시스템은 신뢰도에 대한 구조요소의 역할과 기여도를 고려하여 모델링 된다. 따라서, 구조시스템의 신뢰도는 구조요소의 모델링과 구조요소의 상관관계에 따라 서로 다른 결과를 제시하게 된다. 최초 구조시스템의 신뢰도 평가와 열화요소를 반영한 구조시스템의 수명 평가를 바탕으로 생애주기 비용 최소화와 관련된 목적함수를 가지는 최적화 과정을 통해 수명관리가 이루어진다. 본 논문에서는 구조시스템을 구성하는 구조요소의 상관관계와 더불어 기존의 연구에서 고려된 바 없는 유지보수 간의 상관관계에 따른 수명평가 영향분석을 수행하며, 이를 통해 향후 좀 더 효율적인 수명관리 기법 개발에 활용하고자 한다. 또한, 예방유지보수와 필수유지보수를 모두 고려하며, 유지보수간 독립 상태와 완전상관 상태에 따른 수명 예측 및 최적화 유지보수 계획 수립을 비교 제시한다.

  • Objective: The objective of this research is to study preceding literature on safety culture surveying tools and indicators used in aviation organizations to help the further understanding of aviation safety culture by presenting Korea-Safety Culture Survey Indicator (K-SCSI) as a relevant case. Background: The aviation field puts a great deal of effort in preventive safety management through the application of Safety Management System (SMS), which was co-developed by international aviation organizations such as ICAO and FAA. To successfully operate safety management system, safety culture factors such as the organization member's level of consciousness, attitude and faith regarding safety must be put together. However, the aviation field currently lacks programs to promote safety culture and the exact understanding of some safety culture concepts. Method: This research inquired into the definition of safety culture in the aviation field and the surveying tools used to measure it. It then described the development and application process of the Korea-Safety Culture Survey Indicator (K-SCSI) mainly focusing on case studies. Results: In this research are presented safety culture promoting programs that can be applied to subordinate indicators of K-SCSI such as organization commitment, management involvement, rationality of reward system, employee empowerment and reporting system. Conclusion: For a mature safety culture to settle successfully, it is essential that safety culture survey indicators are developed and applied in a way that fits the organization's features. Also, behavior measuring indicators are required to develop a more objective indicator and thus must be standardized. Application: Cases that deal with the development and application of safety culture measuring tools within the aviation field can be studied and applied in other domains to spread safety culture.

  • The goals of nursing education, and the bases for evaluating them depend on the goals of nursing practice. In order to prepare for the coming twenty first century and the meet changing societal demands and health needs, it is necessary to develop a new conceptual framework for future nursing education. While hospitals will still be in significant components of the health care system, will no longer be central focus or dominant influence. Health care services will be more usually delivered at community base. The nursing education required by that new approach must provide for reconsidered about a concept of caring as nursing curriculum. The changes in health care delivery that have occured, now being proposed, for nursing education undergoing its own changes. So the philosophy and objectives of education meed to reconsidering about the caring concept and general nursing. Nurse educators must prepare students to practic in condition of constant change. At the same time nurse educators must emphasize preparation about that. The practice of science of caring in nursing draws on a basic knowledge of the behavioral knowledge, biophysical processes, pathological processes, nursing skills and procedures and various treatment regimes and problem solving to help decision making in nursing situations. The concept of care is probably one of the least understood ideas used by professional and nonprofessional people, yet it is probably one of the most improtant concepts to be understood by nursing. Human caring and human relationships are closely interrelated. Humn caring remains an essential dimension of professional work and the science of caring as essental to the discipline of nursing. It is expected that the objectives of nursing education will be accomplished when the course and content of the curriculum are based on this conceptual framework. One recurrent education goal with some consistency is that of equipping the student with the necessary skills to live effectively and productivly in the world of tomorrow. In the new vision we are developing, professional education must also include exposure to liberal arts, encouragement of critical thinking, and a moral context for advanced professional education that is based upon a contextual health policy and caring science educational model.

  • The term 'nursing' is often defined as a therapeutic and interpersonal process that ultimately functions to help clients. In the process of helping, empathic ability(ability to entering into the another's feeling or motives) is an essential factor that has been proved in the fields of psychology and social psychology. In the sense, nursing personnel with high level of empathy is required to accomplish the comprehensive nursing. The purpose of this study was (1) to investigate empathy between nursing and non-nursing students, (2) to examine changes of empathic ability in accordance with their academic years, and (3) to show relationships, if any, between the two concepts, empathy and need-affiliation. For the survey, 325 respondents for nursing department and 378 from non-nursing departments were randomly selected from the two universities in Seoul. The instruments used in this questionaire survey method were Hogan's Empathy Scale and Mehrabian's Need-Affiliation Scale, each of them has established its validity and reliability in many different people and settings. For the analysis, descriptive stative statistics were mostly used by calculating frequencies, percentages and mean scores. T-test, analysis of variance and correlation coefficient were employed to test the differences and the statistical significance. The results of this study are summarized as follows: (1) There was no significant difference in empathic ability detween the nursing and non-nursing student (2) The levels of empathy among the nursing students, 'surprisingly enough, were negatively correlated with their academic years, even though statistical significations was not found. The scores of the empathy are somewhat dropped as academic year going up. (3) No significant relationship was revealed between empathy and need-affiliation. In conclusion, the results of the study repeatedly support the claim that the nursing education must empathize and, also, include the programs that enable nursing students to develop the ability of empathy for their clients.
