In complex industrial world, many companies make every effort to analyze their competition capability through various performance evaluation tools to cope with rapidly changing business environment. Among evaluation tools the balanced scorecard (BSC), put forward by Kaplan and Norton in 1992, is a strategic performance management tool for measuring whether the smaller-scale operational activities of a company are aligned with its larger-scale objectives in terms of vision and strategy. The BSC tool offers a comparative advantage over others to evaluate the objective achievement of a company by linking its strategic objectives with operational KPI. In this paper, we introduce a case that the BSC performance evaluation system was implemented based on product data management and applied it to the business process. Specially, we shows a implementation procedure to derive discipline-specific topics and key performance metrics.

Ergonomic product design considering users' natural use motion is of importance to improve the usability and satisfaction of a product. A five-step process of product design was developed in the present study by measuring and analyzing users' natural product-use motion with a motion capture system. The developed process was applied to ergonomic design improvement of a half guard installation part of refrigerator; new guard designs (diagonal and arc shape) were developed with the process and evaluated in terms of validity during the development as two measures (task satisfaction and similarity of natural motion). According to the evaluation result, the satisfaction at putting in- and out-task of new guard designs ($6.3{\pm}0.5$ points) was significantly higher than that of existing guard designs ($3.3{\pm}1.0$ points); the difference between natural motion and product-use motion in new guard designs ($1.0{\pm}0.3cm$) was significantly less than that of existing guard designs ($2.0{\pm}0.2cm$). The proposed process of natural motion analysis and product design is applicable to ergonomic product design and evaluation.

본 연구는 제품의 미적/기능적 속성 수준과 브랜드 파워가 제품평가에 미치는 영향력을 연구하였다. 피험자에게 제품사진과 정보를 제공하고 호감도 및 품질평가를 지시하였다. 연구결과, 브랜드 파워가 낮은 제품보다 브랜드를 제시하지 않은 제품이 더 높게 평가되었으며 이러한 경향은 감성적 제품의 경우 더 뚜렷하게 나타났다.

본 논문에서는 한일공동VLBI상관기(Korea-Japan Joint VLBI Correlator, KJJVC)의 핵심 구성시스템인 VLBI상관서브 시스템(VLBI Correlation Subsystem, VCS) 본제품의 1차 성능시험에 대해 기술한다. VCS 본제품의 1차 성능시험의 주요 목적은 현장에 설치하기 전에 제작사에서 다양한 시험항목을 대상으로 시험을 수행하여 문제점을 확인 후 전체 시스템의 완성도를 높이는 것이다. 이번 성능시험에서는 VCS 시작품에서 발견된 FFT 재양자화의 유효비트 부족으로 인한 오버폴로어 문제점을 포함한 기능적인 시험을 수행하였다. 이번 VCS 본제품의 공장시험을 통하여 2008년 VCS 시작품의 성능시험에서 발견한 FFT 의 재양자화 문제점이 완전히 해결되었으며 VCS 본제품에 지연추적, 지연보상, 주파수 묶음 등의 중요 기능도 추가되었다. 그리고 실제 관측 데이터(광대역/협대역)를 이용한 상관처리 시험에서도 예측되는 상관결과가 출력되는 것을 확인하였다.

Domestic LCD TV market is composed of two groups of products produced by major firms and small and medium enterprises. The major companies make the price relatively high, but the other makes lower in the same sizes. The model of the low price products does not make consumers choice when they choose LCD TV. This makes the questions of capability between difference price products. The reason above mentioned, the firms that include group of comparatively lower price, are worried about not increasing sale because of prejudice. This study is to find any interrelationship and evaluate the efficiency between the products using performance, exterior and brand power of product. In order to do this, a hybrid AHP/DEA evaluation model for comparison/valuation of LCD TV products is developed. The proposed process is; first, to derive hierarchy structure of LCD TV evaluation criteria using axiomatic design, second, to calculate the score of each LCD TV product through AHP analysis including weight calculation of evaluation criteria, and last, to evaluate the efficiency of LCD TV product by applying DEA by defining product scores as output and prices as input. It concludes that the high price products shows good efficiency, but there are some products with good exterior and brand power, not performance, also presenting good efficiency.

The purpose of this study was to clarify differences in the product attribute evaluation in relation to the objective knowledge, subjective knowledge and involvement of apparel. The measurement instruments were developed by researcher on the basis of previous studies in the same field. The subjects of this study were female adults who lived in Seoul, Kyunggi or Incheon areas and quota sampling using age and residential areas was employed. The data were obtained from 603 questionnaires. Data were statistically analyzed using SPSS 10 and LISREL 7.0. Major statistical methods were factor analysis, Cronbach's a coefficient, multiple regression analysis, and structural equation model analysis. The results were as follows: 1. Involvement was related to the consumer knowledge and the knowledge influenced evaluation of intrinsic attributes, social attributes, and economic attributes. 2. The dimensions of objective knowledge significantly influenced intrinsic attributes and economic attributes. The dimensions of subjective knowledge significantly influenced intrinsic attributes, social attributes and economic attributes. 3. Apparel involvement significantly influenced intrinsic attributes, social attributes and economic attributes. Consumers who have higher interest in apparel product but not in trends considered intrinsic attributes more importantly, whereas consumers who care trends considered social attribute more.

In this paper, we propose an AR-based tangible interaction using a finger fixture for virtual evaluation of digital handheld products. To realize tangible interaction between a user and a product in a computer-vision based AR environment, we uses two types of tangible objects: a product-type object and a finger fixture. The product-type object is used to acquire the position and orientation of the product, and the finger fixture is used to recognize the position of a finger tip. The two objects are fabricated by RP technology and AR markers are attached to them. The finger fixture is designed to satisfy various requirements with an ultimate goal that the user holding the finger fixture in his or her index finger can create HMI events by touching specified regions (buttons or sliders) of the product-type object with the finger tip. By assessing the accuracy of the proposed interaction, we have found that it can be applied to a wide variety of digital handheld products whose button size is not less than 6 mm. After performing the design evaluation of several handheld products using the proposed AR-based tangible interaction, we received highly encouraging feedback from users since the proposed interaction is intuitive and tangible enough to provide a feeling like manipulating products with human hands.

This study aims to examine if a consumer's evaluations of and purchase intentions towards textiles and apparel-related cultural products are influenced by their culture, as indicated by their nationalities. Additionally, several psychological variables, such as novelty-seeking tendency, world-mindedness, and familiarity with Northeast Asian culture were included in the analyses to compare the relative importance of cultural influences with the importance of individual characteristics. To conduct a quantitative analysis, we collected data from 400 female consumers in two countries: 200 from the USA and 200 from China. Key findings showed that, nationality and novelty-seeking were found to have a strong influence on purchase intention when product evaluation variables were not included. Evaluation of appearance and Northeast Asian design emerged highly significant predictors of purchase intention for Korean cultural products, regardless of the product type. Cross cultural comparative research on cultural product evaluations is extremely rare. This study focused on groups of consumers residing in the US and China and asked them to evaluate a series of textiles and apparel-related cultural products produced in Korea.
