The purpose of this study was to examine the effects of science class using the multimedia materials on high school students' attitude toward science. The subjects were 222 high school students. For this study, 11th graders at a high school were assigned to a comparison group and an experimental group. The experimental group was received science class using multimedia materials for 3 months. The research design was pretest-posttest control group design, the data were analyzed using PASW statistics 18.0 program. The types of multimedia materials used in experimental group were science fiction movies, science documentaries, TV programs, and Power Point presentations created by students. Before and after treatment, the attitude toward science tests were administered. Pre-tests and post-test score differences between 2 groups were analyzed by ANCOVA. The differences of attitude toward science based on gender were compared by analysis of covariance. And the perception on science class with multimedia materials were also investigated. The results of this study were as follows: First, the attitude toward science was improved significantly after applying science classes using multimedia materials. Especially, there were significant difference between pre-test and post-test in the score of attitude toward science class and attitude toward science content which were sub-area of attitude toward science. Second, there was no significant difference between female and male students in total score of attitude toward science. However, the attitude toward science, scientists and society, which was a sub-area of attitude toward science, female students scored significantly higher than male students. Third, 84% student showed a positive perception that the science class enhanced their interest in science. 69% the students responded that we had thought about Science-Technology-Society. Multimedia material types which the students prefered were science fiction movie, science documentaries, science TV programs, respectively.

In the past days, most of studies about users' behavior in online environments have been mainly focused on the adoption of website and internet shopping or shopping mall. But the generic model of website usage behavior has not been made and the leading theory of website usage behavior has not been existed. The purpose of this study consists of two parts: (1) to find the determinant variables of the website users' continuous using Intention in a certain website, (2) to examine the relative influences of the variables influencing the users' behavior in online environments. The framework of this study is based on the combination of some theories - Davis(1989)'s TAM, Fishbein(1975)'s TRA, Hoffman et al.(1997), Schneiderman(2000), Yoon(2002), Lee and Turban(2001), Sultan et al.(2002), Shankar et al.(2002a, 2002b), McKnight et al.(2002), Chen and Dhillon(2003), Heijden(2003) and so on. Major findings of this research are summarized as fellows: First, determinant of website continuous using intention was affected by 1) the-attitude and 2) the trust of the website except of perceived usefulness. Second, the website attitude was affected by the perceived usefulness, design, experience, reputation. But perceived ease of use did not affect the website attitude. Third, the website trust was affected by the perceived usefulness, perceived ease of use, design, experience of website. But the reputation of website did not determine the trust of Website in this research model.

In this paper, an enhanced method for attitude determination is proposed for systems using an IMU (Inertial Measurement Unit). In attitude determination with IMU, it is generally assumed that the IMU can be located in the center of gravity on the vehicle. If the IMU is not located in the center of gravity, the accelerometers of the IMU are disturbed from additive accelerations such as centripetal acceleration and tangential acceleration. Additive accelerations are derived from the lever arm which is the distance between the center of gravity and the position of the IMU. The performance of estimation errors can be maintained in system with a non-zero lever arm, if the lever arm is estimated to remove the additive accelerations from the accelerometer's measurements. In this paper, an estimation using Kalman filter is proposed to include the lever arm in the state variables of the state space equation. For the Kalman filter, the process model and the measurement model for attitude determination are made up by using quaternion. In order to evaluate the proposed algorithm, both of the simulations and the experiments are performed for the simplified scenario of motion.

This study was performed to examine attitude, perception, and sensory evaluation of Jjigae HMR (Home Meal Replacement) for Americans in the L.A. area. Attitude and perception of Jjigae were conducted by 128 consumers. The questions were as follows: 1) frequencies and attitude toward soup and stew, 2) experience and frequency of Korean food intake, 3) awareness of Korean Jjigae. A total of 69.5% of American had previous experience with Korean foods. However, the frequencies of Korean food intake were once every few months (27.4%) or once a year (18.9%). The 20.2% of consumers selected Kimchi-jjigae as the best-known Korean Jjigae, and 17.1% of consumers had previous experience with Kimchi-jjigae. However, the 23.7% of consumers did not have experienced with Jjigae. Sensory evaluation was conducted using Sundubu-jjigae and Kimchi jjigae. Overall liking and flavor liking were conducted by Americans using a nine-point scale (1: Dislike extremely - 9: Like extremely). The degree of intensity for sensory attribute was also rated using a nine-point Just-About-Right(JAR) scale (1: not nearly spicy/sour enough, 5: Just-About-Right, 9: too spicy/sour). Purchasing intention was rated using a five-point scale (1: Definitely would not purchase, 5: Definitely would purchase). Overall liking and flavor liking of two jjigae (Sundubu-jjigae & Kimchi-jjigae) had a value higher than five on the nine-point scale. The level of spiciness of Sundubu-jjigae was suitable for consumers whereas spiciness of Kimchi-jjigae was significantly different from the JAR value of five points on the nine-point JAR scale, showing that Kimchi-jjigae was significantly spicier than JAR point. Purchasing intention had a value higher than three on the five-point scale.

The purpose of this study was to identify the effectiveness of science writing on organizing scientific knowledge and improving science process skills and science attitude, as science educators have indicated. For this study, two classes of $5^{th}$ grade students were chosen in the same elementary school. Subjects were divided into an experimental and a control group. The students in the experimental group took part in a science writing program for 14 lessons of science classes. The students in the control group were taught according to the traditional science program using standard science textbooks. To identify the effects of science writing, both groups' students were tested on science achievement, science process skills, and science attitude before the program implementation and were tested on science concept, science process skills, science attitude after the program implementation. The results of this study showed that the experimental group gains significantly higher scores than the control group in science concept and science attitude, but there was no significant difference on science process skills for either group. In conclusion, science writing had positive effects on science concept and science attitude of elementary school students, helping them to express their thinking logically and systematically, but science process skills were not affected.
