  • Despite the growing online exposure of retailes, offline retail channels still outperform online channels in the total retail volume of some countries. There is much interest in the physical layout plans of retail stores to expand sales. Product placement that have a large impact on customer purchasing behavior at offline retailers influences customer movement and sales volume. But in many cases, each retailer relies on unsystematic and autonomous product placement. When multiple products are sold with one purchase, the customer's movement for shopping may be evaluated in terms of customer efficiency and additional impulse purchase. In this paper, the social network is applied to sales data of a retail store and the result is used for evaluation of product placement and customer path. The frequent sales product composition was identified using k-core from sales data in the form of shopping baskets. The location was checked for the identified compositions of products, the spatial variance was measured and the customer's path was identified. With these results, the store arrangement of products was evaluated with appropriate improvement directions. The analysis method of this paper can be an alternative analysis approach for better layout of retail stores.

  • The purpose of this study was to investigate product evaluation on consumer's buying behavior of domestic & imported golf wear brands. The questionnaires were sent to 200 consumers who play golf. The 119 data were analyzed by mean, t-test, ANOVA and chi-square. The results of the study were as follows: There were significant differences on consumers' evaluation of apparel quality on fabric and style between groups. Consumers evaluated that the imported golf wears made of more soft, light and unique fabric than domestic, and had a unique and characteristic style. The evaluation of apparel quality according to demographic information has significant difference. Consumers(46-55 ages, business managers and professional) evaluated imported brands were made of soft and light fabric. Consumers(business managers) buying imported brand evaluated dry-cleaning was inconvenient. Consumers who engaged in service industry evaluated domestic brands were easy to coordinate with other items.

  • The purpose of this review was to suggest practical criteria for the clinical translucency evaluation of direct esthetic restorative materials, and to review the translucency with these criteria. For the evaluation of reported translucency values, measuring instrument and method, specimen thickness, background color, and illumination should be scrutinized. Translucency parameter (TP) of 15 to 19 could be regarded as the translucency of 1 mm thick human enamel. Visual perceptibility threshold for translucency difference in contrast ratio (${\Delta}CR$) of 0.07 could be transformed into ${\Delta}TP$ value of 2. Translucency differences between direct and indirect resin composites were perceivable (${\Delta}TP>2$). Universal and corresponding flowable resin composites did not show perceivable translucency differences in most products. Translucency differed significantly by the product within each shade group, and by the shade group within each product. Translucency of human enamel and perceptibility threshold for translucency difference may be used as criteria for the clinical evaluation of translucency of esthetic restorative materials.

  • The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the resulting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or systems they will buy and operate. In this paper, we propose a selection guide for If products by showing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

  • In this paper, the concept of design for environment (DFE) was introduced to mechanical design and manufacturing of cellular phone case. A new evaluation method integrated in existing product manufacturing process was developed and applied to two different types of cellular phone cases: foldable type and slider type. The evaluation results suggested that scores for 'refurbishments & recycle' criterion were relatively low for their cases. This evaluation method may assist designers to draw a checklist of the product's weak points from the perspective of DFE. From the checklist, the designers can consider possible improvements in future design.

  • Evaluation indices for products or services are important to improve the internal process of the company and to compare those with competitive ones. The sigma level in Six Sigma management does important role to evaluate the core characteristic, CTQ(Critical To Quality), derived in the considered product/service or process. In this research, we propose an overall evaluation index for the product/service or process with multiple characteristics, in other words, multiple CTQs. The proposed overall evaluation index is useful for the cases that the single CTQ is not enough to evaluate the practical interests, for example, the final products and services with complex procedures and relatively large scaled processes. This approach is discussed with sigma level for applying Six Sigma Projects, however, it is applicable to indices based on proportion or percentage as well. The practical examples with a manufacturing process and a customer survey based on focus group interview are given for illustrations.

  • Driven by the vague assessment big data, a product service system (PSS) evaluation method is developed based on a hybrid model of multi-weight combination and improved TOPSIS by relative entropy. The index values of PSS alternatives are solved by the integration of the stakeholders' vague assessment comments presented in the form of trapezoidal fuzzy numbers. Multi-weight combination method is proposed for index weight solving of PSS evaluation decision-making. An improved TOPSIS by relative entropy (RE) is presented to overcome the shortcomings of traditional TOPSIS and related modified TOPSIS and then PSS alternatives are evaluated. A PSS evaluation case in a printer company is given to test and verify the proposed model. The RE closeness of seven PSS alternatives are 0.3940, 0.5147, 0.7913, 0.3719, 0.2403, 0.4959, and 0.6332 and the one with the highest RE closeness is selected as the best alternative. The results of comparison examples show that the presented model can compensate for the shortcomings of existing traditional methods.

  • 본 연구에서는 창의적 산출물 평가의 대표적 도구인 O'Quin과 Besemer(1989)의 '창의적 산출물 분석행렬(CPAM)'과 '창의적 산출물 어의 척도(CPSS)'의 두 가지의 산출물 평정 척도를 적용하여 동일한 산출물을 평가하는 데 있어 평가 결과의 차이를 분석하였다. 연구 결과, 창의적 산출물 평가에서 평가자의 암묵적 지식은 존재하며, 암묵적 지식과 명시적 지식에 기반한 평가의 평정결과는 차이가 있는 것으로 나타났다. 평가자에게 명시적 지식이 쌓여 갈수록 산출물에 대한 전반적인 평가 점수는 낮게 나타나 더 엄격해지는 경향을 보였다. 상대적으로 세분화된 채점기준을 가진 CPSS로 평정하였을 때는 창의성의 하위 차원에서 점수가 모두 낮게 나타났으며, 평가자가 산출물에 대한 첫인상이나 개인적 평가 기준이 너무 확고한 경우에는 평정도구에 영향을 받지 않을 수도 있다는 것을 살펴볼 수 있었다. 영재교육 담당교사들은 창의적 산출물 평가에서 전문가들과 유사한 평가를 하고 있었으며 산출물 평가 도구를 사전에 충분히 숙지하고 산출물을 지도하거나 평가한다면 보다 새롭고, 유용하고 적절하며, 해결성이 높은 창의적인 산출물이 생성 될 수 있을 것이다.

  • 본 연구는 대학생들이 주도적으로 학습역량을 강화하기 위해 참여하는 튜터링 프로그램 사례를 CIPP(Context-Input-Process-Product)모형을 통해 평가하고 분석함으로써 대학 튜터링 프로그램의 질적 개선을 목적으로 한다. 이를 위해 B대학교에서 2016년 2학기에 실시한 튜터링 프로그램에 참여한 학생 중 최종보고회에 참석한 학생 90명을 대상으로 튜터링 설문조사 및 만족도 조사를 실시하였다. 또한 튜터 49명을 대상으로 튜터중간간담회를 실시하였고 튜터링에 참여한 234명이 제출한 성찰일지를 분석하였다. 상황평가의 경우, 튜터링 프로그램의 필요성 측면에서, 투입평가의 경우, 인적·물적 자원의 적절성과 프로그램 기획의 적절성 측면에서, 과정평가의 경우, 교수학습활동 과정 측면에서, 산출평가의 경우, 영향력, 효과성, 지속가능성, 전이성의 측면에서 튜터링 프로그램을 평가하였다. 설문조사 평가결과, 상황평가 평균 4.05점, 투입평가 평균 3.88점, 과정평가 평균 4.08점, 산출평가 평균 3.92점으로 나타났다. 튜터 간담회 분석결과와 성찰일지 분석결과에서도 유사한 분석결과가 도출되었다. 학습자가 모든 평가항목에서 보통 이상의 수준으로 만족하고 있는 것으로 나타났으나 평가내용 중 상대적으로 낮은 평가점수 영역에 대해서는 구체적인 개선방안을 통한 프로그램의 개선이 필요하다.
