A golden period of modelization for new industrial product R & D project selection was 60s-7Os. Many models, in this period, were advented. But its level of usage showed lack of enthuiasm extremely. Therefore, the trend in 70s held back. But in recent years the importance of R & D project selection modelization is reembossing. The idea screening stage or R & D project selection decision is deficient decision area in the new product process. Most quantitive and economic models focus on the commercialization stages, while idea screening models are largely speculative and arbitrary, This paper presents an empirically derived and validated new product screening model. Typical screening variables were measured for each of 62 actual new product projects. Ten dimentions were found to describe the screening domain. A multiple regression model was derived from the real data and when validated using a cross-split-half method, yielded a predictive accuracy of 85.2 percent.

This study was to explore the characteristics of Saudi Arabian Learners" strategies of learning Korean language. For data collection, this study employed a survey questionnaire, oral interviews, and learning journals focusing on the use of diverse strategies. According to the data analysis, the participants appeared to frequently use social strategy and meta-cognitive strategy. The findings also showed that the participants preferred to use rather simple strategies based on mnemonic strategy and cognitive strategy. By the way, the learners with high academic achievement or in upper classes tried using meta-cognitive strategy and social strategy. We also found that they felt difficulty using various learning strategies when learning Korean. Therefore, to improve their ability to use appropriate strategies, they should learn to choose the most suitable one for each task and situation flexibly. Although the generalizability of this study is really limited owing to the small number of the participants, we find it quite meaningful as it examined the learning strategies generally used by Arab learners of learning Korean language who have scarcely experienced Korean language education.

Argument is one of the common features that people cannot avoid in their lives. Korean language learners are also bound to deal with various arguments from trivial ones in daily lives to academic discussions. During an argument, ``questioning`` plays significant roles beyond a mere language behavior to ask for specific information. Nevertheless, ``questioning`` tends to be overlooked in Korean Language Education. In this background, this study has deducted some implications by comparing the functions of questioning strategies that Korean native speakers utilize with the ones found in Korean language textbooks. As the result of analyzing Korean native speakers` discourses, we have found that questioning conducts or develops an argument and conveys information effectively. On the other hand, in majority of Korean language textbooks, the strategic function of questioning to control the flow of an argument were not reflected enough. Only a few textbooks discussed the function of questioning to convey information effectively. When considering the importance of strategic functions of questioning in argumentative discourse, it is necessary to focus on questioning strategies more than we do now in Korean Language Education.
