To compete global marketplace, many firms are adopting product families to increase variety, satisfy customer requirements, shorten lead-times and reduce costs. The key to a successful product family is the platform from which it is derived. When designing product families, it is important to resolve the tradeoff between product commonality and distinctiveness. To measure the commonality within a product family, it is necessary to develop the commonality index. It utilizes different parameters such as the number of common components, their cost, their manufacturing processes and so on. This paper present a new product family assessment index using the benchmarking method and considering environmental performance called green product family index(GPFI). Through the comparison analysis between some previous developed commonality indices and GPFI, we verify the suitability and effectiveness. Eventually, the proposed a new green product family assessment index can be helpful to design and develop the environmentally conscious product families.

The objective of this work is to produce solid biofuel from sawdust using the HTC (Hydrothermal carbonization) process. The HTC process of feedstock involves the raw material coming into contact with high temperature and pressurized water. The HTC process could produce gaseous, liquefied and solid products, but this study focused on solid product only as an alternative to coal. In this study, sawdust used for a feedstock and its moisture content was under 5%. Water was added with the feedstock to raise moisture content to 80% and also used catalysts. The HTC process was performed at temperature range from 200 to $270^{\circ}C$ and reaction time was 15 to 120 min. Rising temperature resulted in increasing the higher heating value (HHV) of HTC product. In case of adding catalyst, HHV of solid biofuel was higher and reaction occurred at lower temperature and pressure. Also, HTC solid product had been characterized and found to be hydrophobic, increased HHV (over 40%), and pelletized easily compared to raw material.

In this study, we present a new product strategy corresponding to the needs of the consumer segment in the mobile convergence industry, which is a field with a very high interest, and the implications are as follows. First, we believe that mobile convergence will lead the market for products that are regarded by consumers as innovative. Second, it can be seen that it is more attractive to consumers to dramatically improve existing functions than to add multiple functions that are not so important. Third, the type of convergence preferred by each type of consumer differs. For consumers who are less innovative, less professional and more technologically fatigued, it was shown that breakthrough improvements in existing technologies lead to better evaluations than adding multiple innovations. In addition, highly innovative consumers are more likely to appreciate the addition of a variety of mediocre features, such as less convergent innovations than the existing ones, as well as mobile convergence. Moreover, there was no significant difference in the product attitudes between the consumers with low technological fatigue and the highly innovate ones.

We describe a new method to initialize the raster and convergence of a flat intelligent tracking (F!T) tube. By splitting up the initialization algorithm into three parts, it can comply with the variety of boundary conditions that are stated for a consumer product. Experiments on raster initialization have shown that the new algorithm speeds up the initialization by one order of magnitude.

Many researches have concluded that product advantage or superiority is the most important factor for the commercial success of new products. However, the specific dimensions of product advantage have not been studied as yet. In order to know what kind of product attributes have been major determinants of commercial success, telecommunications winning products from 1985 to 1997 in the Korean market were examined. As results of the analysis, the determinants are classified into function, aesthetics, economy, safety, usability, reliability, brand image, assurance, distribution channel, advertisement, DEF(design for the environment). This study augmented the data set through questionnaire survey to marketing professor in University. The results will be a cue to future of new product development.

To increase the competitiveness of domestic manufacturers products, CAE system, process and fast delivery of development information and implementation of retrieval system introduced for manufacturers is necessary situation For this purpose, this study analysed instance to build integrated design simulation system that provide design automation, modular design, design standards, automation of quality verification and design knowledge. Also, we discuss that improve design of the new product and increasing the satisfaction of our customers. Completed development of simulation systems are the basic steps, and pilot operation about new product. During pilot operation, the systems is improved. Through this process, the experimental data accumulated to increase the effectiveness of the simulation, and improve the utilization. Therefore, this study have many theoretical, practical value for growing global company.

Today, home gardening is in the spotlight. Therefore, the necessity of developing a new type of gardening product was raised according to the consumer's desires. This study, the contents were developed using sparrows, a helper who helped the bean rat's grain-cracking task among the characters of 'kongjwi patjwi'. The cultural contents convergence product is a lid production that is used at the end of the plant support. The fabrication method was designed using UG NX program after design research, and after printing by 3D polyjet method, mold was made and cast into silicon and resin. Through product manufacturing, we could confirm the public's interest in the possibility of new products and creativity. In the future, it is expected that the development of products incorporating cultural contents through various cultural archetypes will be activated, contributing to the enhancement of economic added value and national brand value.

This paper aimed to exam core factors of the success factors of new products and analyze their effects on success. To accomplish this purpose, this study examined previous studies and summarized core factors of success factors of new products. From previous studies, we drawed core factor. Core factor is technology factors(marketing skills, technical skills), specific of new product(more innovative, less innovative, cost advantage, competitive advantage), the process of product development(crossfunctional integration, staff involvement). Except for more innovative factors, the others factors affect on success. To be winner, companies must be consider these key factor(less innovative, cost advantage, competitive advantage, cross-functionalintegration, staff involvement).
