To meet standards for high quality of care and satisfied customers, an evaluation tool about nursing care is necessary. And, We need to evaluate our practice continuously for the improvement in quality and outcomes. This study was intended to develop an evaluation tool about nursing care in NSICU, and was progressed of 3 steps; development, content validity verification and reliability verification. Data were obtained and analysed from Feb. To April, 2000. Development process of the study was as follows A preliminary list was made item by item on the basis of clinical Experience, literature review and patients' record review. Then the standards, criteria and indicators of preliminary evaluation tool were set by 5 clinical nursing panel, and their content validity was reviewed by 27 ICU nurses. Finally, an evaluation tool was developed and verified the reliability at c-university hospital located in Kwang-Ju. The results of this was as follows 1) The evaluation tool of this study developed 8 standards, 39 criterias and 106 indicators. The standards were divided into two dimensions. One was process dimension which contained 4 standards(26 criteria), The other was outcome dimension which contained 4 standards(13 criteria). 2) the Average content validity of the tool was 3.39 at standards, 3.55 at criteria and 3.51 at indicators. 3) Interrater reliability of the tool is r=.7993(p<.001) & internal consistency reliability ${\alpha}$ is .6031 4) Scores of NSICU Patients who participated in this study were 57 at total mean score, 58 at process mean score and 56 at outcome mean score The evaluation tool developed in this study seems to be useful in evaluation nursing practice appropriately for the improvement of nursing care in NSICU. I hope that this evaluation tool can be used effectively in NSICU as an intervention for the improvement of quality control.

이 연구의 목적은 신뢰도와 타당도가 확보된 계절 변화 개념 검사 도구를 개발하고 계절 변화 개념과 관련된 하위 개념과 오개념에 대하여 객관적으로 관찰하고 분석하여 변인 간의 관계를 설명하고자 하였다. 계절 변화 개념 검사 도구의 개발 과정은 검사 도구 개발 계획 수립, 검사 도구 초안 개발, 예비 검사 및 검사 도구 수정, 최종 검사 도구 개발, 본 검사 실시의 과정으로 이루어졌다. 개발된 검사 도구는 학생의 계절 변화 개념 형성 정도를 검사하고 개념 형성에 어려움이 있다면 그 원인이 무엇인지 분석하여 적절한 학습과 도움을 제공하는데 활용할 수 있다. 개발한 검사 도구를 이용하여 6학년 198명을 대상으로 한 회귀 분석 결과 선수학습개념의 이해정도와 오개념의 교정 정도는 계절 변화 단원에서 학습한 개념에 정적으로 유의미한 영향을 미치는 것으로 나타났으며, 특히 오개념이 더 큰 영향을 미치는 것으로 나타났다. 평균 점수를 기준으로 절단점을 생성하여 구분한 두 구간 중 평균 점수 이상 구간 학생들은 오개념의 교정 정도가 유의미한 영향을 미쳤으며, 평균 점수 이하 구간 학생들은 선수학습개념의 이해정도가 유의미한 영향을 미쳤다.

제품라인공학 기반의 융합소프트웨어 개발 방법론에서는 어플리케이션 개발을 위해 아키텍처 모델을 제안하고 있다. 그리고 명세를 이용하여 제어컴포넌트를 개발하도록 제안하는데 워크플로우는 트랜잭션을 주로 처리하는 어플리케이션 개발을 위해 제안되었다. 제품라인 공학 기반의 소프트웨어 개발이 효과를 발휘하기 위해서는 도구의 지원이 반드시 필요하다. 하지만 기존의 워크플로우 모델링 도구들은 제품라인 공학개념을 지원하지 않기 때문에 워크플로우 기반의 제품라인 소프트웨어 개발을 지원할 수 있는 도구의 개발이 필요했다. 본 논문에서는 워크플로우 기반의 제품라인 소프트웨어 개발을 지원하기 위해서 개발된 도구를 소개하고 개발된 도구의 활용 가능성을 확인하기 위해서 간단한 활용예제를 소개한다.

It is the concept of this paper to build up the convergence type of the total class service system, and the goal is to develop the education services, which are differentiated from existing digital textbooks and development tools. We establish developmental programs and convergence strategies from market analyses related to apps and digital education. Then this paper proposes 'E-Class Author Service System (ECA)' as an education service system based on the tablet PC. It is the convergence system of the app type of textbook development tool and class management system. Teachers can produce and develop class materials and textbooks using the app type of textbook development tool in ECA service system. They can also add necessary functions from the class management system for efficient class progress. ECA improves the interaction and communication between a teacher, student and parents in the sever-based network. This study expects that ECA will achieve prior occupation of the app market as an educational app development tool and reduce private education expenses.

In this research, a tool was developed for the rapid performance of three-dimensional finite element analysis (3D FEA) of a machine tool spindle system made of a shaft and bearings. It runs the FEA with data, such as the bearing stiffness and the coordinates of the points, to define the section of the shaft, bearing positions, and cutting point. developed for the spindle system and then implemented with the tool using an object-oriented programing technique that allows the use of the objects of the CAD system used in this research. Graphic user interfaces were designed for a user to interact with the tool. It provides rapid evaluation of the design of a spindle system, and therefore, it would be helpful to identify a near optimal design of a spindle system based on, say, static stiffness with design changes and, consequently, FEA.

This paper describes a development of the PLD design tool in considering with a device fitting. To design digital circuit with PLDs, several steps in the developed PLD design tool are needed such as Boolean description step, pin map step, FUSE map and JEDEC steps ... etc. Especially, we have considered the device fitting to design large digital circuits with PLDs developed the device fitting algorithms based on the PLD device fitting and compared with the results of a another PLD design tool(PALASM). Also, we have proved that the developed PLD design tool is successfully implemented by the connection with a PLD writer(ALL-07), in the case of design digital circuits.

In this study, a rigid multi-body dynamic model has been developed for mechatronic analysis to evaluate dynamic behavior of a machine tool. The development environment was the commercialized analysis tool, ADAMS, for rigid multi-body dynamic analysis. A simplified servo control logic was implemented in the tool using its functions in order to negate any external tool of control definition. The advantage of the internal implementation includes convenience of the analysis process by saving time and efforts. Application of this development to a machine tool helps to evaluate its dynamic behavior against feeding its component, to calculate the motor torque, and to optimize parameters of the control logic.

The diffusion of fuzzy logic techniques into real applications requires specific software supports which save development time and reduce the programming effort. But we has been lack of a tool devoted to support the design of fuzzy controllers. In this paper, on the basis of the general fuzzy set and .alpha.-cut set decomposition of fuzzy sets, a set of fuzzy reasoning tool(FRT) devoted to support the design of fuzzy dontroller for servo systems is developed. The major features of this tool are: 1) It supports users to analyze fuzzy ingerence status based on input deta and expected results by three-D graphic display. 2) It supports users to prepare input data and expected result. 3) It supports users to tuned scaling factor of membership functions, rules and fuzzy inference. The paper shows how the suggested design tools are suitable to give a consistent answer to the tuning of fuzzy control system. This FRT is expected to exert good performance and devoted to support which the design of fuzzy controller is illustrated in the servo systems.

The fundamental issues to evaluate machine tool's performance through simulation pertain to the physical models of the machine tool itself and of process while the practical problems are related to the development of the modular software structure. It allows the composition of arbitrary machine/process models along with the development of programs to evaluate each state of machining process. Surface roughness is one of the fundamental factors to evaluate machining process and performance of machine tool, but it is not easy to evaluate surface roughness due to its tribological complexity. This paper presents an algorithm to calculate surface roughness considering cutting geometry, cutting parameters, and contact dynamics of cutting between tool and workpiece as well as tool wear in turning process. The designed virtual machining system can be used to evaluate the surface integrity of a turned surface during the design and process planning phase for the design for manufacturability analysis of the concurrent engineering.
