Recently, OOM(Object-Oriented Method) access method which begins to apply to software development is emphasizing development cost and time reduction through independent software reuse. But because of planning to the exclusion of the lack of knowledge and expansion or performance for development technology many problems are coming out. Therefore, this thesis suggests Effective Object-Oriented Modeling methods considering the plan for higher productivity enhancement of software in the software development life cycle. Effective Object-Oriented Modeling method includes, methods, Use Case modeling methods, Analysis Modeling methods, Design Modeling methods and others.

이 논문은 기존의 Use Case 방법론을 개선하려는데 초점을 두고 있다. Use Case 방법론의 설계단계 중, 설계 프랙티스(Design practices)단계에 소프트웨어 테스팅 개념을 적용하였다. 이 방법은 먼저 사용자의 요구 사항을 상호작용 다이어그램을 통해 분석하고, 설계 컴포넌트(Design Component Units)라고 불리는 기능적 컴포넌트들로 새롭게 정의하고 추출한다. 추출된 기반을 바탕으로 생성된 설계 컴포넌트들을 설계 스키마(Design schema)에서 계층구조로 분할하는 방법이다. 여기서 개발자들의 목적에 따라 선택한 수 있도록, 다양한 기준에 적용한 수 있는 여러 가지 설계 컴포넌트들을 정의하였다. 개선된 Use Case 방법론을 토대로 변환 알고리즘[11]을 이용해 새로운 Use Case 툴을 개발하고자 한다.

The purpose of this paper is to introduce the development of a new Lesson Video-Case Lab (LVCL) program in Suzhou, China. This program involves the creation of several series of hypermedia video-cases on teaching and learning designed to facilitate mathematics teachers' professional development. Each of these video-cases consists of lesson clips, case questions, interviews with experts, comments by peers, responses by students and other related resources. The study has implications pertaining to the use of technology in teacher development, the production of hypermedia video-cases, as well as research on case-based pedagogy and pedagogy in general.

The Consultation about Energy Use Plan is prescribed by the Energy Use Rationalization Act. In order to reset Examination Criteria for Energy Use Plan, consultation case analysis from 2001 to 2010 were carried out and National Energy Master Plan was reviewed. This study proposes that Examination Criteria for Energy Use Plan be should divided into Urban & Tourism complex development project and Industrial complex development project for the prevention of civil complain. Also predicts that effect of energy savings calculated by Reset Examination Criteria on $1^{ST}$ energy demand BAU at 2030 is 2.2%, effect of new & renewable energy utilization at 2030 is 3% and the rate of $CO_2$ reduction to greenhouse gas emission BAU at 2020 is 1.1%.

We have to carry out systematic, definite requirements analysis for the successful development of software. The UML gives the ways to grasp user or customer requirements and decide the boundary of business systems from the use case modeling. This paper presents how to extract use case diagram from the requirements specification systematically by applying the standardized rules as a part of the study for use case modeling. We modify requirements specification by applying $R_{RS}$ (Rules for Requirements Specification) and extract actor, use case, relationship by applying $R_{A}$(Rules for Actors), $R_{U}$(Rules for Use Cases) and $R_{R}$(Rules for Relationships) to the modified requirements specification separately and then become to make out use case diagram in the end. By applying the rules presented in this paper to the requirements specification for personnel management, we can reduce the existing difficulties of extracting use case diagram based on the narrative descriptions without any standardized rules.rules.

Use cases are commonly used to represent customer requirements during systems development. In a large software development environment, finding relevant use cases from a library of past or related projects is a complex, error-prone and expensive task. This study proposes an ontological methodology to support use case retrieval in an interactive manner. The architecture of a prototype system that implements this methodology is presented. To evaluate whether the proposed approach can provide satisfactory results to users, this study develops a research model and hypotheses based on interaction theory. These hypotheses are empirically tested using a laboratory experiment which controls information filtering and perceived interaction. Our study suggests that a system which interacts with a user intelligently reduces cognitive load and increases self-efficacy and satisfaction.

In this paper, we suggested a method for game operation tools by Ultrasonic sensor. Various ideas are necessary for the development that a game is industrial. I use a Ultrasonic sensor in this study and use a model case, and an operation is going to hold a case shooting play. Therefore, I showed a former circuit and a formula related to this.

Required system and technology for the civil helicopter and the military helicopter are almost similar. A lot of mount helicopters are converted from military to civil, or converted oppositely, or new developed considering civil-military dual use in order to reduce development cost and period. In the case of converting the military to the civil, the military helicopters are developed based on sufficient requiring amount following conversion to the civil helicopters with minor modification. This paper presents the investigation and the analysis for the case and the approach of dual use helicopter development from military helicopters to civil helicopters.

Purpose: To identify user requirements for electronic nursing record (ENR) systems so as to ensure system usability. Methods: A mixed methods approach were applied in three steps : (i) task and workflow analysis with literature review of nursing documentation, (ii) literature reviews of system usability, and (iii) Use Case idenfication and consensus-based validation. We analyzed the nursing activity logs collected from a time-motion investigation of six hospitals. The Use Cases were validated by eight clinical experts from different hospitals and two experts from academia in a sequential Delphi survey. Consensus was achieved for the significance score and agreement among the panel. Results: Eight task groups and patterns of task flow were observed, which were translated into nine Use Cases. The specification of Use Cases was derived from principles, guidelines, and recommendations on nursing documentation and electronic health record systems, which was organized into three requirements of each Use Case: functionality, information, and design characteristics. Each Use Case achieved an agreement of 50~70%, and significance scores of 4 or 5 on a 5-point Likert scale. Conclusion: The nine Use Case identified were considered to be important and adequate in terms of both clinical and informatics contexts.

As a rational decision-making process of county-level area development, this study designed 3-step framework : function-giving(areal analysis) on unit planning area by decision matrix of land suitability, check of typical characteristics of each function area and formulation of its future development strategies. Two alternatives were suggested as the areal analysis method, of which one is equal ordering / valuing technique of checking indices for land suitability classfication and the other preferential weighting technique. And then, under the algorithm specially defined in this study, land suitability maps(Fig.2,3) of the case study area (Seungju-county area, Chonnam-province, Korea) were drawn from the areal analysis results. By use of land suitability classification results, unique characteristics of typical function areas were defined (on 7 types of alternative 1 , 8 types of II ) and their future development strategies were formulated in the case study area, According to the categorization criteria in this study, all the villages of the case area were classfied as a suitable type of function areas illustrated in this study.
