Objectives: This study was to develop and evaluate a web-based multimedia content for the education of hospice volunteers. Methods: The multimedia content was developed based on Baik's teaching and learning structure plan model. The developed program was evaluated by 24 hospice volunteer university students. Results: On main page, there were 4 menu bars that consisted of a lecture guide, cyber lecture, pause and quiz. In the operation of the web based multimedia content, HTML, Java Script, Photoshop and multimedia technology were utilized. There were significant differences in the test scores, before and after using this web-based learning program. After using a web-based learning program, scores of students were much higher. Conclusion: The developed web based program is based on systematic structure and it can provide hospice volunteers with the educational flexibilities and will be help for them to perform the more efficient hospice care.

Recently, because of the global recession of the offshore plant industry and low-cost orders, there has been increasing interest in strengthening the competitiveness of domestic companies for the design and production technologies of offshore plants. However, in the offshore plant design field, the Plant Design Management System (PDMS), which is a 3D CAD program for plant layout developed by AVEVA Marine, is already commonly used as offshore plant design software and widely used in large domestic shipyards and cooperative design companies. Under this background, we have been thinking about ways to design better with the existing software. In this study, we developed a parametric design program to maximize the efficiency and reduce the working time for offshore plant electrical outfit production design based on the Programmable Macro Language (PML) of PDMS. We also examined its performance. By applying the developed program to the offshore plant module selected as an application example, it was confirmed that a 50% improvement in the work efficiency of cable tray design could be obtained compared with the existing method, with work efficiency improvements of 80% or more in other field design work.

공정관리는 건설 프로젝트의 효율적인 수행을 위한 핵심 역량 중의 하나이다. 공정관리를 수행하기 위한 지원 도구로서 많은 상용 공정관리 솔루션이 개발되었지만, 건설 현장에서는 사용법을 잘 알지 못하고 있는 등 여러 가지 이유로 인해 활용도가 높지 않은 것이 현실이다. 본 연구에서는 설문조사를 통해 공정관리 및 관련 솔루션 사용에 관한 현황 및 문제점을 파악하고, 이를 기반으로 상용 공정관리 솔루션 활용도를 높이기 위한 공정표 작성 지원 프로그램을 개발하였다. 개발된 프로그램을 통하여 현장에서의 상용 공정관리 솔루션의 활용성을 높이고, 결과적으로 효율적인 공정관리를 기대할 수 있을 것이다.

The purpose of this study was to examine the effect of utilization of drawing skills in elementary science class on improving scientific drawing. The learning program has been developed for 5th grade students in the regular classes in order to enhance scientific drawing skills. The program was composed of three steps, understanding the kinds of drawing, imitating sample drawing, representing through observation. The developed program was verified by the science education scholars and teachers. Students trained during 3 hours with scientific drawing skills step by step. As a result, students significantly improved skills in scientific drawing skills. Furthermore, the effect was sustained after a month. On the other hand, there were no statistically meaningful differences on scientific attitudes and preferences.

In this study, a cycle simulation program of a Unit-Injection(UI) system was developed to estimate the injection performance of newly designed injection system. A fundamental theory of the simulation program is based on the conservation law of mass. Loss of fuel mass in the system due to leakage, compressibility effect of the liquid fuel and friction loss in the control volume was considered in the algorithm f the program. For the evaluation of the simulation program developed, the experimental result which was offered by the Technical Research Center of Doowon Precision Industry Co. was incorporated. Two main parameters; the maximum pressure in the plunger chamber and total fuel mass(kg) injected into the engine cylinder per cycle, were measured and compared with the simulation results. It was found that the maximum error rate of the simulation result to the experimental output was less than 3% in the rated rotational speed (rpm) range of the plunger cam.

This study aims at modeling the compositional method in the architectural space and shape. The composition of space is composed of the position and the area in space. Therefore these elements are established to the functional program applied at the behavioral data. The element of spatial structure is position and scale in space, and the composition of spatial shape is developed repitionally to the combination of build-up method. The functional program is being expertised and the scale in building being lager, the importance of functional program is increased. Applied at data of the functional program at spatial structure, the process is developed to the method of combination. The purpose of this study is approached at the degree of application in modeling on the compositional method in architectural space and shape, which is a fundamental aspect on the quantitative analysis of architectural space.

본 연구에서는 액체로켓엔진의 가스발생기와 연소기의 연소현상을 화학평형의 관점으로 접근하여 주어진 압력과 혼합비 하에서 연소가스의 화학조성을 Gibbs 자유에너지 최소화기법을 이용하여 계산할 수 있는 프로그램의 개발을 다루었다. 기존에 개발되어 연소해석에 광범위하게 사용되고 있는 NASA의 CEA code와의 해석결과 비교를 통하여 새로 개발된 연소해석 프로그램의 정확성을 검증하였다.

This paper describes the development of machining simulation program which is able to design cutter profile and 3-dimensional geometry for rotors in screw compressor. Based on the symmetric rotor profiles developed previously, cutters are designed and 3-dimensional geometries of rotors are generated by using simulation program. Symmetric rotors are manufactured by a universal milling machine, and surface geometries of them are measured by a 3-dimension scanner It is shown that simulation program developed is useful to design cutter for rotor manufacturing and to generate the 3-dimensional helicoid geometry of rotor in screw compressor.

It is a time since sustainable architecture become a main issue of design concept in 21C. However, it is necessary to develope the tool estimating energy loads and uses in our architectural conditions for energy saving design. This study aims to develope the E-Load program to predict heat and cooling loads of houses. The program is developed by modified bin methods derived from ASHRAE TC 4.7. It consists of 4 divisions such as files, data inputs, energy load estimations and output options. The main processes of energy load estimations are based on ASHRAE fundamentals. The developed E-Load program is a easy and valid tool to predict heat and cooling loads of buildings.

A simulation program has been developed to evaluate operator seat vibration for earth-moving machinery and decide whether a seat meets the requirements imposed by ISO 7096. An operator seat is assumed as a linear system composed of a mass, a spring, and a damper mounted on a platform. The program evaluates the transmissibility at resonance, and the SEAT factors for a light person and a heavy person. The developed program can be utilized effectively in designing a new operator seat.
