In the existing system that recommends through review data analysis, it does not reflect personal preference details such as user's characteristics or product purchase tastes, in this paper, we propose a system that provides customized recommendation information to various users by selecting the criterion that the user thinks most importantly when searching for the product and purchasing the product, and analyzing it. This is because the user's personal preference is reflected by arranging the product list based on the criterion that the user occupies the largest portion of the product purchase, so that it is more efficient than the recommendation through the recommendation system.

A new product development is critical to the growth and success of most business firms. Increasingly, the new product development is recognized as an essential component of the corporate plan. But, relatively few research investigations have focused on the elements of a new product development strategy and its performance results. This study aims to identify the patterns of new product development strategy which business firms adopt, and its performance results. To identify these patterns and results, 268 firms in four industries known to be active in new product development were selected as a matter of convenience, and surveyed by the questionnaire and interviews. The questionnaire is composed of 67 strategy variables, 8 performance variables, and other variables. To analyze the data from samples, various statistical methods such as factor analysis, Pearson correlation analysis, sluster analysis, and one-way ANOVA were employed. This analysis brought forth the following major findings: First, three new product development strategy patterns were identified. Each strategy pattern was proved to be different from the others in terms of group of strategy elements that were adopted. Second, the new product development strategy was closely linked to its performance. Third, the difference of performance results among strategy groups in each industries was rather significant, however, the performance difference among industries in each strategy group was less significant.

Purpose - This study illustrates research product industrial engineering, which needs to be promoted to encourage knowledge intensive businesses. Research traditions related to industrial business products and a fuzzy multi criteria decision approach in technology management for product design industries have undergone continuous changes over time. However, there is no clarity on the present situation, and there is a need to reform business enterprises. Research design, data, and methodology - Using fuzzy theory and appraising multi-goal plans, the manner of promoting the competitive advantage of industrial businesses is analyzed using a case study. In the case study, various aspects are examined, such as product design and manufacture, fuzzy set decisions with multi attribute policy making, flaws in the present system, and a review of the related literature. Results - New fuzzy and multi criteria designs can improve the existing keyboard by solving product problems, resulting in a clear and durable typeface for a creative LED keyboard. Conclusion - Using a fuzzy set with multi attribute policy-making influences the achievements appraisal system and can help achieve the anticipated strategy goal of product design.

The widespread use of packaging materials on food packages sometimes causes off-flavor and deterioration in the food by migration of packaging materials which consist of mainly plastic materials and printing ink solvents. Even though migration of the residual packaging materials does not generally cause safety problems in the contained food, it certainly can generate off-flavor and finally deteriorate quality of the finished product. In highly consumer-oriented markets, quality of the finished product is gaining more importance economically, so profound and thorough study about migration into food to maintain the fine quality of the end product becomes an importance issue. Studies have been conducted about migration of various packaging materials and the chemical reactions between the food components and the materials used for food packaging (Brody, 1989; Mcneal and Breder, 1987; Lawson, G and Lawson, C, 1996). Several of these studies have measured partition coefficient values (Kp) between packaging materials and various food samples and involved finding factors that affected the partitioning behavior of packaging materials into the contained food. However, to enable prediction of partitioning, data are still needed on the relation of packaging material chemical structure and properties to partitioning behavior, and on the partitioning behavior of various food ingredients and the total food compositions.

With an advent of XML(extensible markup language), researches on electronic commerce based on XML have been conducted by many organizations and companies. Although these researches described electronic catalogs, they are not sufficient because in the catalogs, the product information are not classified properly, and are not organized hierarchically. In this paper, we analyse and classify information that can use to describe various products. And then, we suggest the modes that can describe the various products information through the complement of existing researches, and we apply it over several products on the Web. The uses of this model supports flexibility and facility to the product offers such as internet shopping malls.

The purpose of this study is to analyze the various types and areas of recent collaborations in fashion industry and to find the utility value of collaboration. Seventy seven cases of fashion collaboration marketing strategies were selected from officially announced literature survey and enterprises information around the world. Among the seventy seven cases of fashion collaboration surveyed in this study, collaboration with other fields made up 59.7 percent, collaboration between the same fashion categories made up 40.3 percent. Among the areas of other fields, collaboration with IT(Information Technology) or Motor enterprises were included and made up 36.4 percent. Collaborations with Culture and art world that fashion brands collaborate with world-renowned industrial designer or artist and star entertainers were also included and made up 23.3 percent. Among the areas of the same categories, collaboration of fashion designer and sports or casual brand made up 22.1 percent. Collaborations of home shopping mall and fashion designer made up 18.2 percent. Collaboration cases surveyed in this study were classified according to three types; co-product development, co-branding, and co-marketing. Collaboration for co-product development made up 72.7 percent. Collaboration for co-branding made up 27.3 percent. Collaboration for co-marketing made up 37.7 percent. These collaboration marketing strategies are very efficient to upgrade brand image and cut the marketing cost by creating new target, product, brand, and promotion through successful partnerships. Therefore, much more various types and areas of fashion collaborations should be developed to create something new for future consumers.

There have been many problems to apply SPC(Statistical Process Control) which is a traditional process control technology to the process of multi-product, small-sized production because a machine in the process manufactures small numbers, but various kinds of products. Therefore, we need the new process control system that can flexibly control the process by setting up the SPEC rules and the KNOWHOW rules. The SPEC rule contains the combination of diverse conditions to specify the characteristics of various products. The KNOWHOW rule is based on engineers' know-how. The study suggests the Rule-base Process Control that can be optimized to the multi-product, small-sized production. It was validated in the process of semiconductor production.

The interrelation into nucleation and thermodynamic parameters of solutions has been established by plotting of various dependencies: the enthalpy of dissolution, solubility product and super-solubility on ionic salt radii and also the extent of deviation from an ideal Debye -Huckel model of electrolyte solution on solubility product. The possible methods of perfect crystal growth from aqueous solution have been found a priori by separating of known set of pair values of solubility and super-solubility into no less than six-nine characteristic and distinctive sub-sets.
