This paper presents a study on product design optimization to reduce the environmental impact of machining. The objective is to analyze the effect of changing the product design parameters such as its dimensions, and basic features on the environmental impact of machining process in terms of its energy consumption, waste produced and the chemicals and other consumables used up during the process. To realize this objective, we used a CAD model of a product with different design scenarios, and analyze their energy consumption using an environmental impact calculator method developed. The waste produced, and the consumables used up, such as lubricants and coolants were analyzed using environmental emission factors. Optimization methods using Genetic Algorithm and Goal Programming are applied to the product design parameters in order to get the best possible product dimensions with the least environmental impact of the machining process.

This paper presents an integrated object-oriented database approach for managing the evolution of products in agile manufacturing environments, Schema evolution modification facilities are provided to support full potential versioning of type definitions. All of the possible versions for a composite product are not explicitly represented to avoid version proliferation. However, valid configurations of any composite products can be provided to comply with customer demands, The attributes of composite products are classified in order to provide well-defined representation scheme for composite products and to be exploited in version control. The attributes are partitioned into composite-related and non composite-related categories. Composite-related attributes consist of subproducts and description ones. Subproducts attributes represent physical constituents of a composite product. Description attributes represent external features, assembling, and correspondence property. Interface attributes are introduced for managing configurability and version propagation. Version derivations due to the changes to the interface attributes are propagated toward the product composition hierarchy, The validity of configurations of composite products is checked by using configurability maps. Instance objects which represent the actual product instances are stored and manipulated in the database in order to support traceability during product life cycle.

This study examined the impact of various product photo features on the attention of potential consumers in online apparel retailers' environment. Recently, the method of apparel's product photo representation in online shopping stores has been changed a lot from the classic product photos in the early days. In order to investigate if this shift is effective in attracting consumers' attention, we examined the related theory and verified its effect through laboratory experiments. In particular, experiment data was collected and analyzed using eye tracking technology. According to the results of this study, it was shown that the product photos with asymmetry are more attractive than symmetrical photos, well emphasized object within a photo more attractive than partially emphasized, smiling faces are more attractive for customer than emotionless and sad, and photos with uncentered models focus more consumer's attention than photos with model in the center. These results are expected to help design internet shopping stores to gaze more customers' attention.

As a number of product information is increasing in online markets, customers can purchase products with no spatial and time problems. However, in case of an online market, since customers can't see products directly, others' reviews make a big influence to customers. Meanwhile, it is a burden to read all reviews about some products. Therefore, we need to provide refined information to customers as summarizing whole product reviews. In this paper, we explain about the product review summarization system which can provide to customers as show evaluation scores of product features. Natural Language Processing skills and computational statistics are utilized for summarization. Customers can get chances to buy a feasible product that he wants to get through this system. Moreover, Enterprises can find out the needs of customers deeply.

This study examines whether product promotions are influenced by the market standing of promoted products, using social comparison theory (upward versus downward comparisons). It is hypothesized that people in possession of a product that is inferior to the one on promotion express less discomfort about the promotion and use the information more than do people in possession of a superior product. People in possession of an inferior product may also exhibit more positive attitudes toward the product on promotion, but may show poorer attitudes toward their own possessed product than do people with a superior product. This is because people in an inferior socioeconomic position show a strong motivation to improve themselves through upward social comparison, whereas people in a superior socioeconomic position maintain a strong sense of superiority in downward social comparison, which suggests strong endowment effects. The findings mainly support the hypotheses, and suggest that sales promotions are more effective for people who currently own an inferior product, but not for people with a superior product, who have a strong motivation to maintain their sense of superiority. The findings also imply that, in order to attract consumers in the superior market, managers for inferior products need to turn to methods other than sales promotions, which may include introducing a new brand or sub-brand, or emphasizing luxury and modern features. In contrast, managers for superior products may emphasize product functions and attributes of superior products in their promotions, as people with inferior products may consider such information as benefits of the superior products.

An ergonomic evaluation model which can properly evaluate the design of a product or workplaces was developed to evaluate a new product in the early stage of design. Although several evaluation models have been developed and are in use in the field of ergonomics, they lack an integrated framework and analysis techniques. In this research, an ergonomic evaluation model was developed according to the framework which accommodates desirable components of the model. The framework represents the integration of four components: man model, workplace modeller, ergonomic evaluation functions and knowledge bases, which interact with a common object-oriented database. Components were developed individually and integrated with the workplace modeller. The generation and manipulation of man models, workplace modelling, and ergonomic evaluation features such as reach and visibility were implemented. The developed evaluation model has demonstrated distinct advantages of the flexibility to adapt another features for the ergonomic evaluation model and the better usability for users.

Emotion-Specific Physiology may still remain to bean elusive entity even to many of the proponents and seekers, but an ever-growing body of experimental evidence sheds much brighter prospects for the future researches in that direction. Once such Emotion-Physiology pairs are identified, there exist a high hope that some Sense-Friendly Features that are causally related, or highly correlated, to each pair may be identifiable in the nature or man-made objects. On the premise that certain emotions, if and when engendered by a consumer good, may be conducive to an urge “to own or to identify oneself with the product”, presented here is a model of Sensory Engineering that is oriented objectively towards identifying the Emotion-Specific Physiology in order to have the Sense-Friendly Features reproduced in product designs. Relevant and complementary concepts and some suggested procedures in implementing the proposed model are offered.

In the Korean manufacturing industries, it becomes a common practice to carry both design activities and production planning activities concurrently. We should help product design engineers to apply environmental techniques in the design phase. General design engineers are busy enough to provide new technical features and to reduce the product cost. Professionals in the clean technology field should assist the product design engineers by providing the data basis of environmental specifications and appropriate solutions for each product group. This data basis should be easily accessible through internet or other forms appropriate for the personnel computers.
