건설 사업관리를 위해 많은 소프트웨어들이 사용되어감에 따라 데이터 또는 정보 통합이 중요해지게 되었다 이번 연구에서는 건설 정보의 통합에서 설계와 일정 정보의 통합에 초점을 맞추고 있으며, 정보 모델에 관련된 기존의 연구 결과를 분석하여 일정 정보에 대한 일반 모델을 제시하고자 하였다. 이러한 일반 모델은 설계-공정 정보의 연계를 기반으로 설계되었으며, 이를 직접 구현할 수 있는 방안을 제시하고자 한다. 현재 많은 관심을 보이고 있는 개체지향 CAD의 기술을 활용하여 모델에 대한 프로토타입을 구현하였고 이러한 모델이 완성되기 위한 추후 연구 과제도 함께 제시하였다.

The dynamic simulation of machine tools and motion control systems has been widely used for optimization, design verification, control design, etc. There are three main streams in dynamic simulation: structural dynamic analysis based onthe finite element method, dynamic motion analysis based on equations of motion, and control system analysis based on transfer functions. Generally, one of these dynamic simulation methods is chosen and employed for specific purposes. In this study, an integrated dynamic simulation is introduced, in which the structure, motion, and control dynamics are combined together. Commercially well-known software is used in the integrated dynamic simulation: ANSYS, ADAMS, and Matlab/Simulink. Using the integrated dynamic simulation, the dynamics of a magnetic bearing stage is analyzed and the causes of oscillation and noise are identified. A controller design for suppressing a flexible dynamic mode is carried out and verified through the integrated dynamic simulation.

이 논문은 인체치수와 교구에 기초한 일반교실평면크기의 산정에 관한 연구이다. 초등학교의 교육과정은 1960년대 이래로 지금까지 7차에 걸쳐 변화되었으며, 그러한 교육과정의 변화는 초등학교 일반교실의 평면에 반영되어 왔다. 새로운 교육과정인 제7차교육과정은 학급 내에서 다양한 활동을 수용할 것을 요구하게 되었다. 또한 교육부는 1997년 9월 학교시설기준을 폐지하였고, 일반교실의 규모가 교육의 질에 영향을 미치는 것을 고려할 때, 초등학교 일반교실의 크기에도 변화가 필요하게 되었다. 일반적으로 알려진 바와 같이, 각 부위별 인체치수는 키, 나이, 몸무게와 밀접한 관계가 있다. 이 연구에서는 한국인의 각 인체부위 치수를 산정하는데 있어서 키, 나이, 몸무게를 독립변수로 한 회귀분석이 사용되었다. 그 다음 각 부위별 인체치수, 교구 및 책상배열에 따라 일반교실의 크기를 산정하였다.

The importance of software in the engineering field is increasing day by day, so the utilization and understanding of the simulation software in the engineering design stage has become the core competence of the engineer. This study presents a new software education method for multiple systems in the field of mechanical engineering using a workflow execution environment as a sub-module of a computational platform (called EDISON platform) that can incorporate in-house software tools developed by many simulation tool developers. It can execute not only individual software tools such as fluid flow, structure, optimal design, but also conduct connective executions of multiple software tools. Based on this simulation environment, a methodology was proposed that can be applied to convergence types of engineering educations. By properly using this methodology, it is expected that beginning engineers could encourage their specialties understanding the big pictures of the analysis processes.

Purpose: The purpose of this study was to analyze the contents and trend of smoking and smoking cessation related nursing research in Korea and to suggest the directions for future research. Method: Eight nursing professional Journals published by the Korean Academic Nursing Society and by 7 - adult, community, psychiatric, fundamental, obstetrics, pediatrics, administrative- nursing societies from beginning edition to October 2005 were selected. They were examined for the proportion of published research, participants, research designs, key words, measurement tools, and the intervention outcomes in the case of the experimental research. Result: Of the research analyzed, 87 studies were smoking and smoking cessation related research. The Journals, which had published the most number of smoking and smoking cessation research were J of Korean Academic Society, J of Korean Adult Nursing Society, J of Korean Community Nursing Society. The most popular research design was an descriptive design. The major concepts studied were related psychosocial variables. Among 87 studies, only 11 were experimental research. Conclusion: Research on smoking and smoking cessation in the nursing discipline are increasing. However more research to test the effectiveness of nursing intervention programs are needed.

Learners are often posited in a paradoxical situation where they are not fully involved in decision making processes on how to learn, in designing their tools. Cognitive artifacts in e-learning are supposed to effectively support learner-centered e-learning. The purpose of the study is to analyze cases of cognitive artifacts and to inquire those design principles for facilitating the learner-centered e-learning. Four research questions are suggested: First, it will be analyzed the characteristics of learners with respect to design of cognitive artifacts for supporting the learner-centered e-learning. Second, characteristics of four cases to design cognitive artifacts in learner-centered e-learning environment are analyzed. Third, it will be suggested the appropriate design principles of cognitive artifacts to facilitating learner-centered learning in e-learning environment. Four cases of cognitive artifacts design in learner-centered e-learning was identified as follows: Wiki software as cognitive artifacts in computer-supported collaborative learning; 'Play Around Network (PAN)' as cognitive artifact to monitor learning activities in knowledge community; Knowledge Forum System (KFS) as a cognitive artifact in knowledge building; cognitive artifacts in Courses-as-seeds applied meta-design. Five design principles are concluded as follows: Promoting externalization of cognitive artifacts to private media; Helping learners to initiate their learning processes; Encouraging learners to make connections with other learners' knowledge building and their cognitive artifacts; Promoting monitoring of participants' contributions in collaborative knowledge building; Supporting learners to design their cognitive artifacts.

Purpose: The purpose of this study is to explore the trends of research related to ethical topics in Korean nursing students. Methods: A total of 131 articles that were published from 2000 to 2020 were analyzed and summarized according to publishing type, research design, subject, data analysis method, main research topic, research variables and instrument. Results: Most studies were journal articles (93.9%) and their most frequent research design was survey (75.7%). The research subjects covered all grades (35.1%) or they were divided between clinical nursing practicum (29.8%) or not (21.4%). The main research topics were biomedical ethics, ethical values, moral judgment and ethics education. Recently, ethical decision making and practical ability in nursing practice were reported. The instruments for measuring variables were limited and the same tools were used several times. Conclusion: Based on the findings of this study, it is suggested that the selection of various research topics and the application of research methods related to ethics for nursing students will continue in response to rapidly changing social phenomena in the future. In particular, it is necessary that research related to ethical and practical ability as well as ethical attitudes and perceptions of nursing students be actively carried out.

본 연구는 제품조형에 대한 언어적 연구로 디자이너들의 연구사례의 유형을 분석하고자 했다. 특히 제품조형의 언어적 개념을 도구와 사고의 관계에서 언어적 관계성을 통해서 창출하고자 했다. 언어적인 영역과 비 언어적인 영역에서 조형언어의 역할이 어떡해 활동하고 있는지를 분석하였다. 특히 디자인 프로세스상에 형성되는 조형언어의 역하로 조형해석과 조형개념 창출 즉 아이디어 창출에 대한 디자인 프로세스의 관계성을 파악하였다. 이러한 조형언어가 디자인 사적인 측면에서의 기원과 최초 연구가(EnzoMari)의 연구사례를 제시하였다. 또한 디자이너와 디자인 관련 학자들의 조형언어에 대한 관심을 언어적 측면에서의 다양한 요소로 나누어 분류하였다. 또한 이러한 분류과정을 통해서 제품과 관련된 추상적 이론과 시스템적인 연구보다 구체적인 실무의 사례와 개별화된 제품조형언어에 대한 연구의 필요성을 가지고 이러한 측면을 강조하여 상호문화적인 측면에서 개별화된 실제 제품의 조형 언어의 차이와 관심의 차이 그리고 상호공존 할 수 있는 제품조형언어의 개념 창출을 향후 연구과제로 제안한다.

The importance of intake system can not be overstressed in the recent heavy duty commercial vehicle design. The basic requirements of intake system are to have less flow resistance and better air cleaning performance which have direct effects on the performance and service life of engine. In order to improve the performance of engine intake system, the flow phenomena in the intake system should be fully understood. With readily availble CFD code, the numerical analysis becomes the more reliable tools for flow optimization in recent design work. In this research, flow field in the intake system was analyzed by STAR-CD, the 3-D computational fluid dynamics code. Especially, the flow inside of air cleaner was thoroughly analyzed. Pressure distribution and velocity profile in the air cleaner and intake duct was obtained. Having the dust seperated from incoming air at the expense of less pressure drop is the ultimate goal for the research.
