The technical proposal bidding system emphasizes the evaluation of the construction company's technical capabilities, with the aim of improving the quality and cost-effectiveness of the construction. However, in the VE analysis and proposal process for technical proposal bidding, the ideas are often reused from similar past construction projects, and the application of new construction technologies/methods is often lacking. Therefore, this study proposes a methodology for managing VE proposal information by integrating it into a BIM model using parametric modeling. This research developed database based on the existing VE proposals and new construction technology/method information from the Korea Institute of Civil Engineering and Building Technology. And by using parametric modeling, the proposed method integrate the VE database with BIM model. The methodology proposed in this study is expected to improve the reliability and effectiveness of VE-related idea proposals in technical proposal bidding.

The technical proposal suggested and published by MIC(Ministry of Information and Communication, henceforth MIC) contains too general assessment elements, which causes qualitative and subjective assessment of technical proposals. Thus, in terms of the technical proposal assessment. It lacks In fairness, validity and accuracy. Furthermore, it has a great deal of difficulty in assessment caused by the inconsistency between proposal planning and assessment methods. Also, each company has different writing format, so it is impossible to make use of its maneuvering data for the assessment. To overcome these weaknesses, our research focused on a quantitative evaluation on development organization, which is a part of organizational and administrative part of the technical proposal suggested and published by MIC. In this research, we divided development organization for the technical proposal into organization, teams, and team members, and then studied addition, deletion and merging for the assessment criteria. For the related study, we chose especially CMM(Capability Maturity Model) from a lot of international and national references, which is a model measuring the maturity of organization, and then we focused on Small-CMM which is available in the small-sized organization. We also suggested input form, description method, assessment elements for the quantitative assessment in the chosen developmental organization, and finally we proposed standard referencing criteria for the assessment. Our study concludes that our assessment method are valid and available in comparison with the previous Delphi method through a validity evaluation test.

The combined use of smart materials, complementing each others' characteristics and resulting in devices with optimised features, is providing new solutions in many industries. The use of ingenious combinations of smart materials has led to improvements in actuation speed and force, signal-to-noise ratio, sensor precision and unique capabilities such as self-sensing self-healing systems and energy autonomy. This may all give rise to a revival for numerous families of smart materials, for which application proposals had already reached a stationary situation. It may also provide the boost needed for the definitive industrial success of many others. This study focuses on reviewing the proposals, preliminary studies and success cases related to combining smart materials to obtain multifunctional, improved systems. It also examines the most outstanding applications and fields for the combined use of these smart materials. We will also discuss related study areas which warrant further research for the development of novel approaches for demanding applications.

기술제안입찰의 주 평가요소 중 하나인 생애주기비용의 적정성은 평가의 전문성을 요하지만 평가에 필요한 시간이 절대적으로 부족하여 경험많은 평가자라 할지라도 단순한 수치 비교에 의한 상대평가에 그치는 경향이 많았다. 이에 본 연구에서는 기술제안입찰로 낙찰자를 선정한 실 사례와 기술제안서를 비교하고 110건의 기술제안입찰 제안서를 비교하여 생애주기비용 중 가장 변동 폭이 큰 유지관리 및 에너지 비용의 불확실성을 분석하였다. 또한 절감된 공사비 대비 유지관리 및 에너지 비용의 절감수준을 정규화하기 위하여 VE지수를 제시하였다. 프로젝트별로 상이한 수선 및 교체 주기, 수선과 교체의 중복, 비수선 항목, 그리고 기타 에너지비 등의 중복 적용이 VE지수의 불확실성을 가장 확대시키는 요인으로 분석되었으며, 이러한 요인의 중복을 제거한 유지관리 및 에너지 비용 산출법을 표본 기술제안 사업 35건에 적용하여 평균 1.38, 표준편차는 1.19를 가지는 VE지수 모집단을 도출하였다. 기술제안 입찰의 평가자는 다수의 제안안 중 가장 합리적으로 산출된 VE지수를 추정하기 위해, 특정 VE지수를 본 연구가 제안하는 모집단 분포에 비교하여 그 확률을 계산하는 결정론적 해석 방법 또는 불확실성을 고려한 확률론적 해석 방법을 사용할 수 있다.

This study aimed to develop methods for technical design education that can be intimately connected to the industrial field. For this, technical design jobs performed in the fields of the domestic and foreign fashion industries and their required competences were examined, and educational methods based on constructivism were proposed. Korean fashion technical designers' works were identified, and then the fashion technical designer's responsibilities and qualifications were collected and analyzed from global employment sites. On the basis of the collection and analysis, hands-on staff members and education experts were interviewed about required competences for the actual business and possible suitable methods for education. The results of research showed that in the case of the US, job systems and relevant duties for technical designers were clearly defined by clothing brands, whereas in Korea, businesses were systematized around vendors, not brands, and as a result the businesses of technical package composition and specification proposals were not performed properly. This study organized the contents of technical design education into fit development and specification, the composition of technical design packages, the evaluation and approval of samples, fit schedule management and fitting, block pattern setting and pattern correction, sewing specifications appropriate for styles and materials, grading, technical terms, and production management. As for the technical design education models, the cognitive apprenticeship model, resource-based learning, the problem-based and anchored model, and the problem-based and resource-based models were proposed.

This study analyzed the impact of sense of self-efficacy on job satisfaction and organizational commitment among technical designers in order to acquire information needed for human resources management in the field of technical design. The study was implemented through a normative-descriptive survey method using a questionnaire. The sample consisted of 217 technical designers working at vendors and agents located in Seoul. The results revealed that there were significant differences in the sense of self-efficacy levels among technical designers according to age and work experience. Personal self-efficacy had a positive influence on both intrinsic and extrinsic job satisfaction, but also on affective, continuance, and normative organizational commitment. In addition, personal self-efficacy had a greater influence on extrinsic job satisfaction than social self-efficacy. Both personal and social self-efficacy influenced continuance commitment while there was no relationship between social self-efficacy and affective organizational commitment. However, a clear relationship was found between both social and personal self-efficacy and normative organizational commitment. Nevertheless, social self-efficacy had a greater influence on normative organizational commitment than personal self-efficacy. This fact demonstrates the need to exert more effort to promote the sense of personal self-efficacy of technical designers. These results could be used to provide appropriate proposals for human resources management in the field of technical design.

Best value is the ultimate goal of the owner and can thus have diverse meanings according to the project characteristic, owner's purpose, user groups' payment capability, etc.. Recently, resettlement problems of the marginalized members in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). It means that a minimized production cost for reducing supply price of housing is a key factor in establishing the best value of the marginalized members. The lowest-price bidding system serves the purpose of ensuring a minimized production cost, but due to the low-cost investments, it creates various problems, such as sloppy construction, lowered quality, an increased LCC, and worsening profitability for builders. Thus, to help them resettle, it is necessary to supply affordable housing geared towards a certain appropriate quality and minimum construction costs. Towards this end, this study aimed to propose a cost reduction bidding system based on a technical proposal. The proposed technical-proposal-based cost reduction bidding system consists of the following components: work-unit-based, project-unit-based, and construction-period-reducing technical proposals. These components are evaluated to select the best bidder for a given project. The technical proposal based cost reduction bidding system proposed herein is expected to provide facilities with appropriate supply prices and appropriate quality levels, to bolster the technological competitiveness of builders.

The Szentgotthard Flood Protection Project is located in the southeasters part of Austria, very close to the Hungarian border and to the Hungarian town of Szentgotthard situated near the Junction of the rivers Lafnitz and Raab. During heavy rainstorms, this area has always been liable to severe floodings, affecting the town itself and upstream reaches, where major industrial and commercial development is planned. In order to solve these problems, several solutions have been developed by means of a series of model tests performed at the hydraulic laboratory of the Technical University of Graz, Austria. The model was constructed to scales 1:75 (lengths) and 1:25 (heights). This trebled scale allowed greater accuracy in the measurement of discharge depths. The results from the model tests have led to the following proposals: - Construction of a flood relief trough with an inflow section 3.5 km upstream of the junction of the rivers Lafnitz and Raab. - Use of a former river bed for the flood relief trough. - Design of a lowered embankment crest section to pass one-third of the maximum flood flow of the river Lafnitz. - Connection of the flood relief trough to the Lahnbach stream, a tributary of the river Raab.
