This study examines the mediating effect of product innovation on the relationship between product development strategy implementation and product development performance of business ventures. The previous researches on product development has mainly focused on the role of venture firms' technological capabilities or that of entrepreneurship in product development. Although there are many important discussions related to the product development of business venture, a more discussion on the relationship between product development strategy implementation and performance of product development is needed. The purpose of current study is to examine the relationship between the entrepreneurial orientation and the R&D department on product development performance. To confirm the model of Day & Wensley(1988) that product novelty mediates the relationship between product development strategy and product development performance. The research results of 703 Korean business ventures suggest that the implementation strategies for product development such as utilizing entrepreneurial orientation and R&D department are more effective for business ventures in terms of product development performance. Also product novelty was prove to be a mediator that intervene the relationships between implementation of product development strategy and product development performance. Those findings may provide implications for whom has interested in the relationship between entrepreneurship and product development performance of business ventures. The differences in between new and existing product performance from the implementation strategy of product development may provide implications for practitioners who understand the process of product development.

The purpose of this study was designed to develope and test the structural model that explains alcohol consumption behaviors among university students in Republic of Korea. The hypothetical model was constructed on the basis of the literature review and Pender's Health promotion model. Data was collected from questionnaires from 512 university students in Republic of Korea, from August to September, 2000. The reliability of instruments was adequate (Cronbach's alpha= .69-.90). Data analysis was done with SAS 6.12 for descriptive statistics and LISREL 8.13 program for covariance structural analysis. The results are as follows; 1. The overall fit of the hypothetical model to the data was moderate. Thus it was modified by male and female models. 2. The revised model has become parsimonious and had a better fit to the empirical data (male: χ2=87.21 p=.00, GFI=.97, AGFI= .94, NFI=.99, NNFI=1.0, CN=619.17, female: χ2=49.29 p=.31, GFI=.45, AGFI= .95, NFI=.99, NNFI=1.0, CN=370.02). 3. Self-efficacy was most significant factor and personality of novelty seeking, reward compensation, alcohol expectancy and drinking attitude have significant effects on male alcohol consumption behavior. 4. Personality of novelty seeking was most significant factor and personality of harm avoidance, friend influence, self-efficacies, alcohol expectancy and drinking attitude have significant effects on female alcohol consumption behavior.

Purpose - This paper examines customers' perception on intra-industry and inter-industry alliance, then compares customer purchasing attitude towards alliance product according to whether it is from high-tech or low-tech industry. Research design, data, and methodology - We used qualitative research methodology of in-depth interviews and focus group interviews. Results - Customers expect products from inter-industry alliance to be highly innovative but also to be inferior in technology. In high-tech industries, since technology is more important than differentiation, inter-industry alliance was negatively evaluated whereas intra-industry alliance elicited positive customer purchasing attitude. Conversely, in low-tech industry where novelty outweighs technology, inter-industry alliance earned positive evaluation. However, for intra-industry alliance, customers' evaluation varied depending on whether both partners share similar prestige and price range. When partners were not similar to each other, customers' perception were positive for less prestigious and pricey brand, but in the reverse case, perception were negative. Conclusions - This research focused on customers' perception and attitude by adopting qualitative methodology while other alliance studies are mostly based on quantitative research. This study provides managers with partner selecting guidelines considering the type of industry, and whether the goal is to enhance novelty or technology.

Purpose: The purpose was to investigate the factors influencing alcohol consuming behavior of the female university students to provide the basic data for a nursing intervention program to improve health and prohibit of alcohol consuming behavior. Method: The subjects were 134 female university students, studying at K university and K educational university in Chungnam province from April 1 to 20, 2002. The instruments were the alcohol consuming behavior scale, that is drinking intensity score, and alcohol problem developed by Shin(1998), refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman at. al.(1989), TPQ scale by Cloninger(1991), depression scale modified by Shin(1977) using Zung(1965)' tool, family cohesion scale by Olson at. al.(1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, canonical correlation and stepwise multiple regression. Result: The most powerful predictor of alcohol consuming behavior was influence of friends-drinking(21.0％). A combination of economic status(8.0％), and personality of novelty seeking(3.0％), accounted for 32.0％ of the variance in alcohol consuming behavior. Conclusion: I recommended that economic status, influence of friends drinking frequently, and personality of novelty seeking were contained of the developing nursing intervention program for decreasing the alcohol consuming behavior in female university students.

This paper presents a new and simple solution for determining the natural frequencies of framed tube combined with shear-walls and tube-in-tube systems. The novelty of the presented approach is based on the bending moment function approximation instead of the mode shape function approximation. This novelty makes the presented solution very simpler and very shorter in the mathematical calculations process. The shear stiffness, flexural stiffness and mass per unit length of the structure are variable along the height. The effect of the structure weight on its natural frequencies is considered using a variable axial force. The effects of shear lag phenomena has been investigated on the natural frequencies of the structure. The whole structure is modeled by an equivalent non-prismatic shear-flexural cantilever beam under variable axial forces. The governing differential equation of motion is converted into a system of linear algebraic equations and the natural frequencies are calculated by determining a non-trivial solution for the system of equations. The accuracy of the proposed method is verified through several numerical examples and the results are compared with the literature.

A kindergarten requires an approach to meet the nature and sense of children who is main users. This study selected 33 private kindergartens which were located within a housing site development zone in Gwangju since the 1990's, had single use, and was constructed in the last five years. Also the image assessment according to types of color scheme was made. Then the factors which affected preference by type were analyzed and the basic of color scheme in a kindergarten classroom was provided. The following results were obtained. First, types of color scheme in a classroom included identity 12.1%, similarity 51.5%, and novelty 36.4% in harmony, but no contrast and achromatic color, Secondly, the assessment of preference according to each type was mostly positive. The highest preference was found in similarity harmony of warm color(e.g. YR, Y) and bright, clear, nice, and strong images were high in assessment. The lowest preference was found in identity harmony of cold color(e.g. GY). This color system had no clear image assessment, except manly or strong. In particular, warm color showed higher preference than cold color in similarity, novelty, and identity harmony. Thirdly, the factors affecting the preference of color scheme in a classroom most were ‘stable - unstable’, ‘clean - dirty’, ‘bright - dark’, ‘nice - not nice’, and ‘vital - dull’.

The introduction of recommender systems to existing online services is now practically inevitable, with the increasing number of items and users on online services. Popular recommender systems have successfully implemented satisfactory systems, which are usually based on collaborative filtering. However, collaborative filtering-based recommenders suffer from well-known problems, such as popularity bias, and the cold-start problem. In this paper, we propose an innovative collaborative-filtering based recommender system, which uses the concepts of Experts and Novices to create fine-grained recommendations that focus on being novel, while being kept relevant. Experts and Novices are defined using pre-made clusters of similar items, and the distribution of users' ratings among these clusters. Thus, in order to generate recommendations, the experts are found dynamically depending on the seed items of the novice. The proposed recommender system was built using the MovieLens 1 M dataset, and evaluated with novelty metrics. Results show that the proposed system outperforms matrix factorization methods according to discovery-based novelty metrics, and can be a solution to popularity bias and the cold-start problem, while still retaining collaborative filtering.
