The design project of a technology product provides an opportunity for students to experience the inter-connectedness of academic information and ill-defined real-world problems. This study focuses on non-engineering students' activity and perception through the assistive technology design project. For this purpose, participants engaged in a team-based technology design project. Then, a qualitative research approach was adopted, which included reflective journals with 24 undergraduate students majored in Adaptive Physical Education. The analysis identified six factors (knowledge value, social value, reality value, accomplishment value, perspective value, benefit value) of perception and five stages (topic selection, function suggestion, visualization, presentation preparation, and presentation) of activity.

It has been found that implementing the function analysis is very important in terms of accomplishing successful Value Engineering(VE), and the function definition is a basic activity at design VE phase. In spite of the importance, the real function analysis activities in the VE are not regard as consequence. In this regard, this paper attempts to use the campus mater plan to lead an effective function analysis. So, the purpose of this value engineering study is to provide the criteria to develop the campus mater plan. This value engineering study used as a guide for the standardization of the campus mater plan. In addition, broader application is possible through the analysis throughout the different ways of the project.

건설 프로젝트의 VE는 크게 설계단계 VE와 시공단계 VE로 분류된다. 설계단계 VE는 정부의 법률에 의해 100억 원 이상의 공공 건설공사에 적용해야만 한다. 따라서 설계VE는 건설 프로젝트에 적극적으로 적용되고 있다. 이와는 대조적으로, 시공 VE는 제한된 특정 건설 프로젝트에 적용되고 있다. 그 이유는 시공 VE 프로세스가 실무적 요구 품질을 반영 할 수 없기 때문이다. 시공 VE는 시공 가능성에 대한 타당성 검증을 통해 긍정적인 효과를 구현할 수 있다. 이에 본 연구에서는 실무를 반영한 시공 VE의 방법을 제안하고자 한다. 제안 방법은 직관지수(G.F.I.)를 활용한 전문가 기반의 대안평가 방법이며, 제안 방법의 적용성을 검증하기 위해 실무사례에 적용하였다. 그 결과 제안된 대안평가 방법은 기존의 방법보다 적용 절차, 적용 방법 측면에서 효율성이 높은 것으로 나타났다.

The new paradigm called 'Low Carbon Green Growth' involved in reducing greenhouse gas is on the rise as a critical issue worldwide. The essential of Kyoto protocol issued in 1997 is to achieve the sustainable economic growth environments by converting existing production system to eco-friendly one. The protocol imposes the liability to reduce greenhouse gas to the countries joined to it. The paradigm is directly involved in the energy consumption and environmental pollution caused by construction activities. Value Engineering which are mainly applied in the design phase in practice is a measure to improve the value of a constructed facility by analyzing and/or appraising the functions and costs of it. However, an appropriate method which assesses eco-friendliness of constructed facility has not been propose by researchers. This paper proposes a method which assesses the performance involved in eco-friendliness of constructed facility using Value Engineering (VE) in the design phase. The method estimates the environmental cost relative to the amounts of energy consumption and environmental pollution occurred over the entire project life cycle. The database called "Life Cycle Inventory DB", which stores information about the amounts of environmental pollution, is used. The algorithm which retrieves the amounts of environmental pollutions from the DB and converts them into environmental costs is developed. The algorithm is implemented into a system which quantifies the eco-friendliness of constructed facility in the design phase using VE.

Railway fields are complicatedly connected with engineering such as physics, civil engineering, architecture engineering, electrical engineering (Telecommunication, signal, catenary, system), machine engineering and performance phase of project in domestic railway can be divided with four steps : planning, design, supervision, construction. Value Engineering is needed to reduce the cost of long period construction duration and periodically maintenance. Currently, railway design is difficult to act optimum design due to limited time, short of manpower, downsized of design company. therefore, VE concept in Design must require In order to solve this problem. it is called Design Management. This paper presents both item of design management and total design management tool of practical aspects, and describes LCC (Life Cycle Cost) analyze process and accomplishment process for applying VE concept

기본설계단계에서 설계자가 건축주 요구사항 만족을 위해 접근하는 방법이 다양하나, 설계과정에서 건축주 및 관련자가 참여하여 정량적으로 설계의 중간과정을 평가하는 것이 부족하다. 이로 인해 설계가 완료된 후에 수많은 변경을 하여 설계자로 하여금 많은 손해를 입게 한다. 이러한 것을 방지하지 위해 기본설계 초기단계에서부터 건축주의 요구사항을 체계적으로 정리하고, 설계자는 그 것을 만족시키는 설계 초안에 대해 건축주 및 관련자들에게 가치평가를 하게한다. 이 후로 일정가치가 이상이 되면 다음 설계단계로 진행되게 하여, 설계가 완료된 후에 건축주의 의도가 제대로 반영되지 않거나 건축주가 의사를 변경하여 발생되는 재설계를 방지하게 함으로써 설계자의 추가 비용을 현저히 줄일 수 있다. 또한 건축주도 설계결과 및 시공결과에 대해 평가하게 하고 건축주의 의도가 제대로 반영되었는지를 알 수 있게 한다. 또한 건축주의 만족도를 평가하게 하고, 건축주나 설계자가 상호 설계 및 시공결과를 정량적으로 확인시켜 시공 후에 발생되는 논란을 최소화 시킨 수 있는 장점이 있다. 본 논문은 설계과정에서 각 결과물에 대해 가치를 평가한 후 일정 전수가 이상 되면 다음단계로 넘어가게 하여 설계자의 손해를 최소화 시킬 수 있다는 것을 나타낸 것이다.

설계VE 과정에서 아이디어 창출은 가장 중요한 부분이다. 그러나 아이디어 창출은 일반적으로 설계VE 팀원의 지식이나 경험을 통하여 진행되게 된다. 설계VE 워크샵에서 좋은 성과를 내기 위해서는 단순하게 설계VE 팀원의 지식이나 경험에 의존하는 것이 아니라 보다 체계적인 접근방법이 필요하게 된다. 본 연구에서는 설계VE 워크샵에서 사용할 수 있도록 TRIZ의 모순충돌 개념을 활용한 체계적인 아이디어 창출방법을 제시한다. 연구과정에서는 TRIZ의 모순충돌 개념을 바탕으로 설계가 가지는 문제영역을 정의하고, 기술적 요인을 활용하여 모순충돌을 나타냈다. 아이디어 창출과정에서 기술적 요인은 설계기능을 향상시키기 위한 체계적 방법론으로 활용됐다. 가시설 공사에 대한 시범사례에서는 본 연구에서 제시한 아이디어 창출절차를 적용할 경우 설계가치를 향상시킬 수 있다는 것을 시범적으로 제시했다.

Industrial products determined by fixed size posses definite limits variety by manufacture tolerance in existence. The optimum value solved by deterministic approaches do not account of tolerance bands of design variables and material properties. If we examine optimum value considering tolerance bands of design variables and material properties, it might be useless, owing to exist infeasible region. We have two ways to prevent being useless value. The one is to minimize tolerance band, the other is to consider tolerance band in optimum design. The former needed more accuracy during manufacturing process require higher production cost, the letter is more appropriate to consider tolerance band. In this research, we consider the tolerance bands of all variables, which might have the tolerance bands used in the problem, based on optimum value of deterministic approaches. Orthogonal arrays are used to minimize the number of trial. Tolerance bands are supposed discretionary according to design variable. Appropriateness suggested by this research is examined through two examples. Mathematical problem is investigated only in terms of tolerance bands of design variables, and cantilever beam problem is explained through tolerance bands of design variable, material properties and loading conditions. It is proved that values from the presented method are satisfactory for tolerance bands of variables.

Optimizing multiple design characteristics which are usually in conflict with each other in the injection molding process is frequently becoming a critical problem for designers who work in this area. The purpose of this work is to develop an automated design methodology for optimizing two such design characteristics found in injection-molded parts. A value function based on decision-making theory is used as a means of evaluating the performance of a two-characteristic design alternative. Also, a design space reduction algorithm based on Taguchi's orthogonal arrays is utilized to discover an optimal design alternative. Verification of the developed design methodology is carried out for an actual model with two design characteristics, the weld line and the gate location, to be optimized in computer simulation experiments.
