This study used 2 coordination tasks to examine the strategy and quality of interactions between mothers and their children. Results were: (1) Most frequently employed strategies of mothers were feedback, orders, explanations followed by questions and opinions. Most frequently employed strategies of children were offering opinions followed by recognition and explanation. (2) In mother-initiated interactions, the mother's-question/child's-opinion sequence was most frequent, and child's acceptance of mother's order, explanation, suggestion, or opinion; child's question to mother's order, and child's explanation were also frequent. In child-initiated interactions, child's-opinion/mother's-feedback occurred most frequently. Mothers' feedback to child's explanation, acceptance, and question was also observed. (3) When mothers and children used strategies of low quality, such as rejection or reprimand, the interactions tended to be negative.

This paper examines "Difference in Requests." The study of speech acts is a crucial area in sociolinguistics and ethnolinguistics, and has aided in the development of TESOL. It also provides a useful means of relating linguistic form and communicative intent. This paper concentrated on 3 request strategies, which were requests made with an explanation, requests made without an explanation and no requests. The purpose of this study, and of concern in TESOL, was to discover whether Koreans framed their requests differently under different conditions. Based on these differences, I wanted to ascertain whether Koreans who spoke English as a second language, and who have lived in the United States, frame their requests as they would in their native tongues thus creating the potential for sociolinguistic failure, or use American sociolinguistic style. As the results of the study, it was found that in the majority of cases, Americans made an explanation with a request. In many cases the Koreans living in Korea would not give an explanation when making a request. Rather, they were direct in request. In many cases the Korean speaking English and living in the US had adopted the American request strategy of giving an explanation.

Providing explanations about recommending actions is one of the most important capabilities of expert systems. In fact, there exist many approaches incorporating this explanation facility into the system. Here we present briefly a new approach to generating these explanations and further attempt to investigate the impact of system explanations on user behaviors toward system-generated recommendations. For this experiment we designed a stock investment decision supporting system which, given a set of market situations, suggests an investment recommendation with explanations about the recommending action. Twenty-nine bank employees evaluated the output of the system in a laboratory setting. The results indicate that explanation facilities can make systems-generated advice more confident to users but cannot increase users'acceptance for the system conclusion.

Technology Acceptance Model (TAM) has been a basis model for testing technology use. Post researches of TAM have been conducted with the updating the TAM by adding new independent variables in order to increase the explanation power of the model. However, one problem is that different independent variables have to be introduced to keep the explanation power whenever applying to particular technology. This reduces the generality of the research model. Thus in order to increase the generality of the model, this study reviewed the previous researches and collected the independent variables used, and regrouped them into three basic independent constructs. New research model was designed with three basic independent constructs with four constructs selected for the mandatory IT environment and voluntary IT environment, and the structured equations analysis(AMOS) was applied to find the significant causal effect relationships between constructs in addition to the explanation power of the model. Finally, this study concluded that new TAM could be used to explain the users' adopting new technology without any adding new particular independent variables.

This study is aimed to prepare the promotion strategy to spawn snow crab resources and create their habitats using SWOT-AHP analysis. Currently, the creation program of spawning and habitat ground (CPSH) of various fisheries resource is a continuing process, however, none of these CPSH can be labeled as being effective in Korea. In order for CPSH to be effective, it must be planned systematically. Therefore, it is necessary for establishing promotion strategy on the CPSH. SWOT-AHP analysis is used to improve explanation ability of SWOT analysis. In this research, we suggested three strategies and 15 implementation plans of the CPSH using SWOT-AHP analysis. It is expected that the economic feasibility, ecosystem and recovery of fisheries resources will improve significantly. Consequently, to increase the performance of CPSH, it is necessary to focus on the developing an efficient and executive promotion strategy on the CPSH.

This study proposes a new instructional strategy and corresponding materials designed from various alternative frameworks to help students understand evolution as a biologically acceptable theory. Biology teachers have normally taught the evolutionary mechanism by means of comparing Lamarckism with natural selection. In this study, a new instructional strategy in which the Lamarckian explanation is first excluded because Lamarckism is known to be subsumed in a learner's cognitive structure as a strong preconception of evolution is suggested for teaching evolution. After mutation theory is introduced, Darwinism including natural selection is explained separately during the next class hour. Corresponding instructional materials that aid student understanding of the evolutionary mechanism were developed using recently published articles on human genetic traits as scientific evolutionary evidence instead of the traditional evolutionary subject matter, giraffe neck. Evolutionary evidence from human genetic traits allows students to exclude anthropocentric thoughts effectively and raise concern for the phenomenon of evolution positively. The administered instructional strategy and materials in this research improved student conception, concern, and belief of evolution and it is believed that they helped students understand the evolutionary mechanism effectively.

The purpose of this study is to do research on correlation between multiple intelligence and e-Learning strategy, which can be used to develop and strengthen e-Learning strategy. The subject was 183 college students of engineering at C university who had ever taken a lesson through e-Learning. Two items are investigated in these college students. One is whether there is a gap and any gender-related difference in multiple intelligence and e-Learning strategy, and the other is what multiple intelligences have an effect on e-Learning strategy. The e-Learning strategy developed by In-Sock Lee and the instrument by Yong-Lin Moon were used. The results of this study are as follows. First, it appeared that there was a difference between gender in musical intelligence and naturalistic intelligence. The average of musical intelligence was higher in female collegian, while the average of naturalistic intelligence was higher in male collegian. But there was no gender-related difference in using e-Learning strategy. Second, it appeared that multiple intelligence gave an explanation of self-direction intelligence up to 31.1%, expression strategy 20.35%, and information processing strategy 16.6%. The results of this study showed that logical-mathematical intelligence affected all of three e-Learning strategies. So, new curriculum which can make use of logical-mathematical intelligence needs to be developed so as to devise efficient e-Learning strategies.
