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.

The study analyzes reviews of hardware products, customer service products, and products that take the form of a convergence of hardware and cloud services in ICT using text mining. We derive keywords of each review and find the differentiation of words that are used to derive topics. A cluster analysis is performed to categorize reviews into their respective clusters. Through this study, we observed which keywords are most often used for each product type and found topics that express the characteristics of products and services using topic modeling. We derived keywords such as "professional" and "technician" which are topics that suggest the excellence of the service provider in the review of service products. Further, we identified adjectives with positive connotations such as "favorite", "fine", "fun", "nice", "smart", "unlimited", and "useful" from Amazon Eco review, an integrated product and service. Using the cluster analysis, the entire review was clustered into three groups, and three product type reviews exclusively resulted in belonging to each different cluster. The study analyzed the differences whereby consumer needs are expressed differently in reviews depending on the type of product and suggested that it is necessary to differentiate product planning and marketing promotion according to the product type in practice.

Following is discovered in this study by some. First, attribute(product/non- product) of that truth that get through experiment of this study is WOM deduced result that have statistical meaning in dependent variable which is public trust only in this study. Specially, information by word of mouth type received High positive response more with non-product information by word of mouth attribute than the product attribute in all experiment products that is parted according to involvement. Consumer's response by involvement level of product can affect for site attitude, public trust, and intention to purchase by second. For example, consumer's site attitude has induced the most positive response, and can confirm positive response of High consumer most in that involvement sensitivity product in that participation reason type product and could confirm response that is the most positive in that involvement reason product even if there is for intention to purchase. Result of this study is grasped that have High mean value relatively in site attitude, product attitude, information by word of mouth effect, public trust, brand attitude, purchase intention etc. generally that product involvement and information by word of mouth attribute are interrelation by third. This can change fairly data processing process according to consumer's Involvement Level, behavior deterministic process, consumer's action with attitude formation process, and involvement for products. High occasion than is low incline more efforts in information retrieval and is discreet result such as study finding of produce.

The purpose of this research is to study the types of name spectrum and their characteristics of domestic men's wear brands focusing on formal and casual wear and also examine the differences based on the type of brands' product and brand style. Total 184 of men's wear brands, which were consisted of 66 formal wear brands and 84 casual wear brands, were selected from '2009 Korea Fashion Yearbook'. For data analysis, quantitatively evaluated the frequency and qualitatively evaluated the image of brand product and the meaning of brand name. The result as follows; 1. The domestic fashion brands for men's wear appeared to have four types of name spectrum. The descriptive name was the most frequently showed, and followed by arbitrary, suggestive, and coined name. For formal wear brands, four types of name spectrum were appeared in the order of descriptive, suggestive, coined, and arbitrary name. In casual wear brands, three types of name spectrum were appeared in the order of descriptive, arbitrary, and suggestive name. 2. The characteristics of men's brand name according to their name spectrum was as follows.; In the descriptive brand names, person's name was used the most and some ascribed the characteristics, feature or geographic location of the product. The suggestive brand names contained images and symbols of the product and also implied the relevant benefit information in a particular product context. In the arbitrary brand name, they imply the various meanings according to the product and are made up of either coined or natural. For the coined name, some bear the ideology or symbolized the characteristics of product itself. 3. The descriptive name spectrum showed the most in domestic menswear brands, regardless of the brand type. Except this, there were differences in the type and the frequency of name spectrum depending on the brand type.

Previous researches on advertising type of extension product have limitations in focusing on adult and simplifying advertising type of extension product as elaborational/relational ad. This study expands to children and subdivides advertising type of extension product by elaborational/relational/elaborational-relational ad. Based on these experimental setting, this study investigates the effects of interaction between age and advertising type in incongruent brand extension. The results show that adult's evaluation on incongruent extension product is the most favorable in elaborational-relational ad. On the other hand, children's evaluation on incongruent extension product is the most favorable in elaborational ad. Based on these findings, theoretical and practical implication and future direction are discussed.

Consumers focus on information about the symbolic meaning of a product for highly involved and emotional products (such as cosmetic products). This study examines the effectiveness of the congruence between cosmetics advertising image and self-image on consumer attitudes. In addition, this study examines two additional moderating effects, which are 'product type' and 'message type'. For the experiment, four advertizing type factorial designs were performed. A total of 320 undergraduate female students in Korea participated in the experiment. This study captured the subjective judgments of consumers on these three comparisons in terms of advertizing attitude, brand attitude, and purchase intention. The results are as follows: First, the greater the self-congruity on cosmetic advertising, then the greater the effectiveness on advertizing attitude. Second, the increased self-congruity on cosmetic advertising did not create greater effectiveness on brand attitude. Third, increased advertizing attitudes on the congruence between cosmetics advertising image and self-image increased the effectiveness on brand attitude. Fourth, increased advertizing attitudes on the congruence between cosmetics advertising image and self-image improved the effectiveness on purchase intention. Fifth, the greater the brand attitude (on the congruence between the cosmetics advertising image and the self-image produced)increased the effectiveness for purchase intention. The results show a significant moderating role of the product type. Marketers can use the results of this study to understand the market of cosmetic products for promotion.

The objective of this study was to identify the cultural characteristics affecting advertising contents of the consumer products. Hofstedes(1991) five cultural characteristics such as individualism-collectivism, power distance, masculinity-feminity, avoidance of uncertainty, confucian dynamism were used. Ten kinds of consumer products were included and data were collected from France, Japan, Korea, and U. S. during 1999∼2000. All ads were evaluated and compared their cultural characteristics in terms of country, product involvement and usage, and magazine type. ANOVA, Duncan test, and Pearson correlation-coefficient were applied to analyze data. The results were shown as follows: First, most ads tended to be individual, less power oriented, feministic, and showed high tendency of uncertainty avoidance as well as long term confucianism for all the countries. And some cultural characteristics were different among countries. Japan, France, U. S. and Korea in order showed higher individualism and lower power distance. Also Korea and Japan showed relatively short term confucian culture while U. S. and France did ling term perspectives in the ads. Second, product involvement and usage type had a significant impact on the characteristics of individualism-collectivism and feminity-masculinity. That is, product ads of lower involvement and personal use were likely to show individualistic messages and to have more feministic appeals. Third, magazine type had an impact on some cultural characteristics. Womens magazines would have more individualistic, less power oriented, and feministic appeals of ads. In conclusion, global ads should be localized and differentiated in terms of some cultural characteristics and differ depending on product characteristics.

Recent advances in technology are evolving to enable individuals to perform various activities necessary for their lives, without being constrained by physical, temporal, and spatial constraints. The online services and experiences that originated from solving the discomfort in the actual offline space have created the newness that can only be experienced in the digital world and furthermore uniquely new experiences in actual space as well. While many previous studies have suggested several interpretations of unique individual behaviors in virtual environments, a recent research approaches virtuality as an interesting perspective of the change of thinking style. Virtuality is defined as how far apart we are from everyday reality, and if the individual faces a situation far from reality, the psychological distance of the individual becomes distant and ultimately leads to the thinking style of high construal level. Otherwise, it is said to have a relatively low construal level of thinking style. In this study, I try to confirm the virtual distance as the role of psychological distance in new virtual contexts. Simultaneously considering temporal distance, which are most used in psychological distance, and virtual distance based on virtuality, this study tries to find whether the effect of virtual distance on product attitude is the same as that of temporal distance and check the relationship between virtual distance and temporal distance in the context of consumers' product evaluations depending on product information type.

The objectives of this study were to investigate differences in shopping style and consumption value of apparel product type, and to establish the effects of consumption value on shopping style. A questionnaire was used to collect data from 263 women aged between 20 to 49 in Gwangju on their shopping style and consumption value according to formal and casual product type. Collected data were subjected to frequency analysis, factor analysis, ANOVA, t-test and multiple regression analysis using statistical program SPSS(version 17.0). Results showed that shopping style could be influenced by six factors: fashion-recreational, quality-brand, impulsive, confused, brand-loyal, and price conscious consumer. Clothing consumption value was influenced by five factors: emotional, functional, epistemic, social, and situational value. Shopping style and clothing consumption value were significantly different between a formal product purchaser and a casual product purchaser. Consumption value had a significant influence on shopping style of the formal product purchaser and also the casual product purchaser.
