In this paper, we examine the relationship between information type and new product development process. Information that was provided for new product development can be divided into two categories. One was relative information that could be used as a basis for comparison such as patent data. The other was absolute information that must be fulfilled in the new product such as key customers requirements. An experiment was conducted with staffs in an R＆D department in order to analyze the impact of the different information types on the development process of new product. It was found that the group with the absolute information recognized the given information repeatedly, which in turn results in a highly technical idea with good teamwork. The group with the relative information created a superior product with better application, appearance and product efficiency through the frequent refinements of given ideas. This paper concludes with the implications of the results to the new product development process and supporting information systems.

Purpose - Nowadays, the innovative design concept is being implemented in product design. In order to satisfy market trends and the demand for quality, designers should employ customer satisfaction questionnaires and analyze them with various experimental processes. Research design, data, and methodology - These methodologies would help designers have a better understanding of their customers and judge the market size and clustering validity, by diverse product strategies, for dealing with the rapid change prevailing in the market today. Results - By considering the innovative design with regard to telephones as an experimental case, the study investigates and demonstrates how the product can benefit from market-oriented and customized management concepts, when creative design ability is utilized for developing the product. Conclusions - Along with the benefit of having an innovative product value, the product can stimulate progress inthe development of the enterprise management, which has emerged as the main issue in the area of social and economic development in every developed country.

In order to satisfy customers'various needs in the market, manufacturing companies tend to add similar variants to an existing product model. This variety causes immense growth of product configuration and makes data management uncontrollable. In order to resolve this problem, we propose a method to efficiently represent the variants in a single schema of product structure and configuration and manage the product configuration. First of all, the product structure which adopts the concept of features and options is suggested. Second, the method to represent option specifications which restricts option configurations is proposed. Finally, the prototype module, which inspects if a product configuration violates the option specifications, is introduced.

This study examined the influences of product knowledge(subject knowledge, purchase experience and information search) on perceived risks and benefits to natural dyeing product. Data were collected from a total of 213 Korean females ranging from 20 to 50 years old who know natural dyeing product through online survey. There were significant differences between(or among) groups with different levels of subject knowledge, purchase experience and information search in several types of perceived risks and benefits to natural dyeing product. Consumers with high knowledge of natural dyeing product perceived several types of risks lower than consumers with low knowledge but they perceived several types of benefits higher than consumers with low knowledge.

In the processing of ocean color remote sensing data, spatio-temporal binning is crucial for securing effective observation area. The validity determination for given source data refers to the information in Level-2 flag. For minimizing the stray light contamination, NASA OBPG's standard algorithm suggests the use of large filtering window but it results in the loss of effective observation area. This study is aimed for quality improvement of ocean color remote sensing data by recovering/extending the portion of effective observation area. We analyzed the difference between MODIS/Aqua standard and modified product in terms of chlorophyll-a concentration, spatial and temporal coverage. The recovery fractions in Level-2 swath product, Level-3 daily composite product, 8-day composite product, and monthly composite product were $13.2({\pm}5.2)%$, $30.8({\pm}16.3)%$, $15.8({\pm}9.2)%$, and $6.0({\pm}5.6)%$, respectively. The mean difference between chlorophyll-a concentrations of two products was only 0.012%, which is smaller than the nominal precision of the geophysical parameter estimation. Increase in areal coverage also results in the increase in temporal density of multi-temporal dataset, and this processing gain was most effective in 8-day composite data. The proposed method can contribute for the quality enhancement of ocean color remote sensing data by improving not only the data productivity but also statistical stability from increased number of samples.

PDM(Product Data Management)은 제품정보 및 개발 프로세스를 관리하는데 많은 이점이 있는 도구로써 인식되어 왔으며, 제품 설계, 제작, 건설, 유지, 보수하는데 필요한 많은 양의 데이터 및 정보를 효율적으로 관리할 수 있다. PDM은 일반적으로 EDM(engineering data management), DM(document management), PIM(product information management), TDM(technical data management), TIM(technical information management) 등으로 알려진 기술의 보다 더 일반화된 개념이다.(중략)

This paper is concerned with the method of estimating lifetime distribution for field data in warranty period and for a situation where some additional field data can be gathered after the warranty period. Implementing the proposed methods in this paper will result in obtaining the more precise product life time estimation and product improvement.

CALS is a strategy to share integrated product data through a set of standards to achieve efficiencies in business and operational mission areas. In this research, we first studied current status for CALS standard and then analyzed the case of US DoD. The results can be summarized as implementing for two major standard in defense CALS system. They are STEP and XML. Our recommendations can be used to set direction for CALS standard implementation and standard selection process.

The environment-friendly agricultural product market receives consumers' great interests despite relatively few studies focused on consumers' decision making process of the environment-friendly agricultural products. This paper examines what factors influence on consumers' attitude and buying behavior on the environment-friendly agricultural product. In order to find the relative importance of each factor's influence, this study adopts multiple regression method based on the survey results of 500 people with the systematic random sampling. The results showed that consumers' favorable attitude towards the environment-friendly agricultural product were influenced by taste, freshness, food safety, and positive attitudes toward the environment-friendly agricultural product promotion. In addition, consumers' purchase intention was influenced by taste, food safety, environmental concern, and the promotion. Respondents recommend the environment-friendly agricultural product when they believe that the environment-friendly agricultural product had the values of taste, environmental concern, and promotion. Women are more active in buying and recommending the environment-friendly agricultural product; however, the price was not the statistically meaning factor. This study provides empirical data that was used for marketing and increasing the sales of the environment-friendly agricultural product. Future research was advised to examine more thoroughly on the relationships between the promotion efforts and purchase intention and the occasions when the price becomes the issue in the buying decision of the environment-friendly agricultural product.
