Currently, the process of selecting products such as construction materials and equipment in the design phase proceeds based on the reuse of products used in the previous projects or samples from design companies as well as information on the limited products provided from the website of several manufactures. In particular, it is urgently required to formulate a standard product information management system that can be utilized in the BIM-based design environment these days. In Korea, domestic construction information classification system was developed, but its utilization has been underestimated since continuous studies on the practical usability are still lacking. Therefore, this paper derived problem of domestic construction materials information system by comparing with abroad material information system. Issues and implication is derived in terms of (1) Input information (2) Provide information, and (3) Utilize Information.

Lighting simulation is becoming increasingly more important as a method for design and evaluation. There is a wide range of packages that provide the accuracy and the usability in lighting simulation. Relux developed by Relux Informatik AG, Switzerland, Relux offers users innovative and high-performance light planning software with open interfaces and simultaneous access to the latest product data from luminaire and lamp manufacturers. The goals of this report is to explore some of the lighting simulation issues relating to Relux. It is hoped that it will provide some background information that will enable a designer and engineer to make some informed judgements on the potential of the current state-of-the-art in computer prediction of lighting in buildings and how this may be used to assist in building design.

전통적으로 기존의 제품은 정적인 환경에서의 학습과 언어적인지가 주요시되며, 제품 조작 시에도 커뮤니케이션의 많은 부분을 시각적 인터페이스에 주로 의존한다. 그러나 운전시 동적인 환경에서의 제품 Interface는 기존의 사용성 평가와는 달리 운전시의 동적인 상황을 많은 부분에서 고려되어야 한다. (중략)

In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.

본 연구는 경북 제1의 마늘 산지인 영천지역의 마늘과 홍마늘의 특성과 생리활성을 평가하고, 이를 통해 액상스틱 가공제품을 개발하는 것이 그 주요한 목표이다. 영천지역 마늘은 난지형 마늘로 20일, 40일 숙성시킨 홍마늘의 경우 숙성이 진행됨에 따라 당/산 비율이 마늘보다 높아 관능적으로 우수하였다. 뿐만아니라 40일 숙성 홍마늘에서 가장 높은 총 폴리페놀 및 총 플라보노이드 함량을 나타내었으며, 항산화능 역시 가장 우수하였다. 마늘보다 홍마늘의 기능성이 우수하지만 지역 마늘 소비 촉진을 위해 우선적으로 일반마늘을 이용한 가공제품 개발 여구를 진행하였고 부원료로는 지역 생산량이 많은 사과, 포도를 활용하였다. 사과 농축액 첨가 제품과 포도 농축액 첨가 제품에서의 일반 성분분석 결과 2종 모두 우수한 관능성을 나타내어 제품화에 적합하였다. 항세균 및 항진균 활성이 나타나지 않았지만, 항당뇨 활성은 기대하기 어려웠다. 하지만 급성 독성을 나타내지 않은 본 제품은 항산화능에서 모두 우수한 결과를 보여 노화억제, 면역력 증강의 효과가 기대되므로 가공제품으로서의 이용성이 높다고 판단된다.

제품이나 환경에 대한 인간의 반응은 생리적 변화로 나타나기도 하지만, 동작 반응(motor-response)으로 나타나기도 한다. 특히 제품으 감성적 설계를 위해서는 가장 기본적으로 이를 조작하는 인체의 자세와 동작에 대한 분석을 필요로 한다. 본 연구는 이를 위해 3차원 동작측정시스템과 힘판(forceplatform)에서 얻어진 원시 데이터로부터 인체의 자세와 동작을 평가하는 소프트웨어를 개발하는 것을 목표로 하였다. 개발된 소프트웨어는 누락 (mission)된 데이터의 보간(interpolation), 동작 애니메이션, 관절의 각도계산, 관절에서의 모멘트(momint)계산 기능등을 포함하고 있다. 본 논문은 진공청소기를 사용하는 동작을 기준으로, 이러한 S/W 개발 과정에 사용한 인체 모델과 각 관절의 모멘트 계산 방법에 대해 주로 기술 하였다. 3차원 동작측정시스템과 본 소프트웨어를 이용하면, 진공청소기, 냉장고 등의 제품을 사용할 때의 사용자의 작업 자세와 부하 평가가 가능해져 감성공학적 제품 개발에 활용할 수 있을 것이다.

Recently, R.O.K. Navy is increasing re-usability of design data and application of M&S(Modeling and Simulation) through the establishment of collaborative product development environment focused on Naval Ship Product Model(NSPM). As a result, the reliability of the result of design is getting better, and furthermore, a study to improve quality of construction through simulation of production/operation is in progress. Accordingly, the database construction of design data and the DB(Database) quality become important, but there was not research related to those or it was just initial state. This paper conducted research about system of the quality verification process of shape elements which compose NSPM based on the quality verification guideline of NSPM as the result of the precedent study. The hull surface was limited as verification object. The study to verify two things that application of basic drawing by the cad model of hull surface, and whether there is error in the geometric quality of cad model was progressed. To achieve this goal, the verification criteria and algorithm were defined and the prototype system which is based on was developed.

Aesthetics of use for modern people can be regarded as being weighted toward universal and rational function since it has focused on an 'automation and efficiency' and 'smartness' in terms of technological and human engineering position. Thus, aesthetics of use as an individual agent has remained in minimal level. This study attempts to seek conceptual model of design regarding the behavior of users from the systematization of critical theories about the usability. To do that, 'HERTZAIN TALES' written by Anthony Dune and the concept and system of Droog Design have been used as a core standard. In line with the various experiments by artist groups such as Fluxus, Memphis group and the work of product semantics, and inherent characteristics of Droog design, which has surfaced from the 1990s, concepts that has mentioned in the Hertzain tales have been organized into main texts. By overcoming cognitive bias inherent in the material culture and by overcoming an existing usability based on immateriality and dialectic solution, the autonomy of critical design and instrumentality of Droog design have been systemized. By interpreting the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use From the interpretation of the design aspect of 12 pieces that have been submitted to the RE;MIND section, the core of this study, it has been confirmed that conceptual and critical design's aesthetics of use has established the autonomy and independence of the behavior of users, created functional articulation of materials and secured new conceptual model and thus, could be an effective methodical clue for creating an emergent design.

This study was to evaluate the usability of self-developed phantom for evaluating automatic exposure control (AEC) using three-dimensions (3D) printer. 3D printer of fused deposition modeling (FDM) type was utilized to make the self-developed AEC phantom and image acquisitions were conducted by two different type of scanners. The self-developed AEC phantom consisted of four different size of portions. As a result, two types of phantom (pyramid and pentagon shape) were created according to the combination of the layers. For evaluating the radiation dose with the two types of phantom, the values of tube current, computed tomography dose index volume (CTDIvol), and dose length product (DLP) were compared. As a result, it was confirmed that the values of tube current were properly reflected according to the thickness, and the CTDIvol and DLP were not significantly changed regardless of AEC functions of different scanners. In conclusion, the self-developed phantom by using 3D printer could assess whether the AEC function works well. So, we confirmed the possibility that a self-made phantom could replace the commercially expensive AEC performance evaluation phantom.
