Automated design program using commercial process integration and optimization program was developed for conceptual design of fighter-class aircraft. Wind tunnel test data and performance analysis results were compared for the verification of analysis tool of this program, and the usefulness of the tool was found. After integration with radar cross section analysis tool, the correlation with configuration design variables of wing, tail and performance parameters was identified by design of experiment, and the optimized configuration for weight and RCS was derived from optimization of empty weight and average frontal RCS value. After parameter definition of fuselage, the program can be implemented for full aircraft configuration.

This paper dealt with developing conceptual model for making public policy on consumer product safety. The matters of consumer safety, public health and environmental protection are essential parts of making policy for consumer products. Moreover, policy authority should consider all measures based on consumer safety. In the process making regulations, policy authority has to have some methods to prevent errors on treating eligible persons as persons disqualified under uncertainty decision making of public policy. To recognize and ensure fairness on public policy, policy authority needs to establish basic policy making and fundamental concepts. Therefore, we developed conceptual model for consumer products safety, CPSPcon in this paper. The conceptual model is one part of SSM(Soft System Methodology) and can support specific policy target. The CPSPcon model can assist in evaluation of responses to an adapting or considering model.

본 연구에서는 상황 학습 이론과 실행 기반의 과학 교육에 관한 문헌들에 대한 고찰을 통해 과학적 실행 중심의 수업에서 과학 개념학습의 가능성을 살펴보았다. 먼저, 상황 학습 이론이 학생들의 과학적 실행에의 참여를 강조하는 최근 과학 교육 개혁의 흐름과 관련이 깊으며, 상황 학습의 관점에서 개념 학습은 학습자가 개념을 자원으로 활용하며 실행에 참여하는 동안 개념적 행위 주체성을 발현하여 개념을 지속적으로 발전시키는 과정을 통해 이루어진다는 것을 알 수 있었다. 또, 이러한 상황 학습 이론은 과학적 실행 기반의 수업에서 과학 개념을 학습하는 데에도 적용된다는 것을 확인하였다. 즉, 과학적 실행 중심의 과학 수업에서는 과학 개념이 자원으로 활용되며, 과학 개념을 자원으로 활용하는 동안 학생들은 과학적 실행에 더 잘 참여할 수 있고, 과학적 실천에의 참여는 개념적 행위 주체성의 발현을 통해 개념 학습을 더욱 촉진할 수 있다. 이러한 고찰의 내용이 학교 과학 교육에 주는 시사점을 논의하였다.

IT environment gets more complicated in terms of open platform, network standards, device design and hardware, etc. Smart network and application are in the fields of corporate as well as national competition for future fusion technology. In development environment focused on computers, the ideas of authoring tool have been presented in terms of improved software productivity. In smart environment where subdividing works are consecutively done, current authoring tool should be effectively updated for effective development of programs and easier access to business works. The basic concept of a new conceptual App development tool, Smart App Authoring Tool, which has been designed in this study and enables to apply on-site requirements to smart phones, is to develop Apps on the level using easy-to-learn Word or Excel in a computer. Therefore, this study is intended to design a conceptual Smart App Authoring Tool to optimize the cost and time for developing and maintaining new application services under various smart phone platform environments. Based on the performance of smart app authoring tool herein, every people can develop a smart app program at moderate level. So this paper have designed a conceptual smart app authoring tool. This study presented educational efficiency of the authoring tool by developing business Apps under various business environments and applying them under university and high school environments.

전투기의 개념설계 과정에서는 기준형상 도출을 위해 비교분석연구가 반복된다. 반복적인 비교분석연구가 자동화되면 효율적으로 기준형상을 도출할 수 있다. 본 연구에서는 비교분석연구의 자동화를 위한 성능해석 프로그램을 개발했다. 프로그램은 형상생성모듈과 중량예측모듈, 임무성능 해석모듈로 구성된다. 형상생성모듈을 사용하여 3D CAD 모델 생성이 가능하며 중량예측모듈에서는 경험식을 사용하여 중량을 예측한다. 임의의 임무형상에 대한 임무성능 해석이 가능하며 최적화 기법을 사용하여 최적 임무성능 계산이 가능하다. 개발된 프로그램의 검증을 진행하여 개념설계 단계에 적용 가능함을 확인했다.

Conceptual studies of a combined-cycle engine have been conducted. Herein, the results are presented. The engine is composed of ejector-jet, ramjet, scramjet and rocket modes, and will be mounted on the Single-Stage-to-Orbit aerospace plane. Propellants are hydrogen and oxygen. Calculated engine thrust performances and cooling requirement of the engine are presented. Pitching moment of the plane with the engine will be balanced even in the vacuum condition. The experimental results of the inlet and the ejector-jet, ramjet and scramjet modes are presented. The effect of the airframe configuration on the engine performance and the thermal environment in the in-side of the plane are also presented. Through the investigations, possibilities of the combined-cycle engine and the aerospace plane are being made clear now.

The purpose of this study was to clarify the concept of LGBT cultural competence in nurses. This study used Walker and Avant's 8 steps of conceptual analysis. The specific steps are: (1) selecting the concept, (2) selecting the purpose of concept analysis, (3) identifying the scope of concept use, (4) identifying the determinant attributes of the concept, (5) presenting model cases, (6) additional cases of the concept (boundary cases, opposite cases, and related cases), (7) identifying antecedents and consequences, and (8) presenting empirical evidence. As a result, five attributes of nurses' LGBT cultural competence were identified in the final 12 articles: cultural experience and cultural acceptance, cultural knowledge, cultural attitude and awareness, and cultural skills. Antecedents included diversification of society, heteronormative healthcare environment, continuing education and training, intercultural understanding, and open-mindedness. Outcomes of cultural competence were identified as reducing LGBT health inequalities and providing quality care. In conclusion, this study contributes to providing a basis for improving the quality of nursing care by providing more culturally appropriate care to the target population through conceptual analysis and understanding of nurses' LGBT cultural competence. Furthermore, it is necessary to continue research on the development of tools to measure nurses' LGBT cultural competence and the development of nursing intervention programmes that can be applied in nursing practice.

In this paper, we have described the characteristics of the Underwater Distributed Sensor Network (UDSN) and proposed the conceptual design guideline by an effectiveness analysis. To perform the effectiveness analysis, we defined an battlefield environment, and then analyzed principal components which compose the UDSN to find out simulation parameters and system constraints. We have chosen a measure of effectiveness based on a target trajectory, which could enhance intuitive understanding about current status, and performed various simulations to reveal critical design parameters in terms of sensor node types, arrangement, cost and combination of detection information.

Background: Goal-oriented communication of risk of hazards is necessary in order to reduce risk of workers' exposure to chemicals. Adequate training of workers and enterprise priority setting are essential elements. Cleaning enterprises have many challenges and the existing paradigms influence the risk levels of these enterprises. Methods: Information on organization and enterprises' prioritization in training programs was gathered from cleaning enterprises. A measure of enterprises' conceptual level of importance of chemical health hazards and a model for working out the risk index (RI) indicating enterprises' conceptual risk level was established and used to categorize the enterprises. Results: In 72.3% of cases, training takes place concurrently with task performances and in 67.4% experienced workers conduct the trainings. There is disparity between employers' opinion on competence level of the workers and reality. Lower conceptual level of importance was observed for cleaning enterprises of different sizes compared with regional safety delegates and occupational hygienists. Risk index values show no difference in risk level between small and large enterprises. Conclusion: Training of cleaning workers lacks the prerequisite for suitability and effectiveness to counter risks of chemical health hazards. There is dereliction of duty by management in the sector resulting in a lack of competence among the cleaning workers. Instituting acceptable easily attainable safety competence level for cleaners will conduce to risk reduction, and enforcement of attainment of the competence level would be a positive step.
