Based on the theory of planned behavior and the theory of legal deterrence, this study takes consumers' willingness to pay for digital music as the research object, investigates the consumers who have digital music consumption channels and behaviors, and discusses the willingness of consumers to pay for digital music and its influencing factors. The study attempts to achieve the following research purposes: First, explore the influencing factors of willingness to pay for digital music using domestic and foreign literature research and related content analysis. Second, we want to examine the effect of Attitude, Collective Specifications, Quality Sensitivity and Music affinity on willingness to pay. Third, Legal deterrence and resource availability tries to verify whether there is a moderating effect between Attitude, Collective Specifications, Quality Sensitivity and Music affinity and willingness to pay. The research data was collected in 2019 between April 6th to May 8th. Questionnaires were randomly distributed in fixed places, mainly in Hubei Province, China. A total of 393 questionnaires were selected for data analysis. Based on the previous theoretical review and empirical analysis, the study draws the following conclusions: Firstly, attitude, collective specifications, quality sensitivity and music affinity have an impact on the willingness to pay. Second, Legal deterrence has a regulatory effect on the relationship among quality sensitivity, musical affinity and the willingness to pay. Last the resource availability has a significant impact on the willingness to pay. It also has a regulatory effect on the relationship among quality sensitivity, music affinity and the willingness to pay.

GPS attitude outputs or carrier phase observables can be effectively utilized to compensate the attitude error of the strapdown inertial navigation system. However, when the integer ambiguity is not correctly resolved and/or a cycle slip occurs, an erroneous GPS output can be obtained. If the erroneous GPS output is applied to the attitude determination GPS/INS (ADGPS/INS) integrated navigation system, the performance of the system can be degraded. This paper proposes an ADGPS/INS integration system using the triple difference carrier phase observables. The proposed integration system contains a cycle slip detection algorithm, in which the inertial information is combined. Computer simulations and flight test were performed to verify effectiveness of the proposed navigation system. Results show that the proposed system gives an accurate and reliable navigation solution even when the integer ambiguity is not correctly resolved and the cycle slip occurs.

In Korea, rotary implements are mainly utilized in the tillage operation. The attitude control system for rolling phenominon of tractors, which in caused due to uneven ground surfaces and sinkage of tractor wheels, is one of the most important control systems in agricultural tractors. The attitude control system of a rotary implement, attached on tractors, was designed and fabricated in this study. The control system was largely composed of four main units; a setting unit, a detection unit, a controller and a hydraulic unit. The implement was controlled by control signals from a computer proportional to controlled errors, on/off action of two directional solenoide valve and lift cylinder on the right lift rod. Response characteristic experiments for the control system fabricated in this study were carried out indoors and outdoors. The results of experiments showed the response characteristics sufficient to use as the attitude control system of rotary implements for agricultural tractors.

This paper presents an attitude determination scheme for the Science and Technology Satellite-2(STSAT-2) using Fine Digital Sun Sensor(FDSS). The FDSS has been developed for STSAT-2, and exhibits the accuracy of 0.032degree in $1{\sigma}$. To be specific, the attitude information from the sensor is exploited to compensate for Fiber Optic Gyro(FOG) mounted on STSAT-2, and Kalman filter model is derived and implemented. To show the effectiveness of the present compensation scheme, computer simulations have been carried out resulting in the attitude errors within a bound.

This study was designed to provide a better understanding of Korean female Internet users' intention to search for information regarding apparel goods and to shop for these goods. Shopping orientation, familiarity, and prior purchase experience were seen as influencing the intention to use the Internet for information search. An important aspect in the search habits that a consumer adopts in gathering information for their buying decisions was Internet shopping attitude. The objective was to predict apparel shopping in terms of prior Internet shopping experience, familiarity, intention to search information via the Internet, and shopping orientation. Internet shopping attitude, familiarity, prior purchase experience, and intention to use to search information were significant in predicting Internet apparel shopping. The most important determinants which influenced Internet shopping were attitude toward Internet shopping and intention to search. In considering the results of the present study, one should recognize the inherent limitations associated with generalizing these findings beyond the sample and the consumer products examined which in this study were apparel goods. Also this study focused on female computer users only. Therefore, future research should utilize more broadly based samples and refine the instrument to distinguish among different apparel products. This study does provide some information that should be helpful to retailers targeting the women's online apparel market.

The purpose of this study was to develop the computer assisted instruction program in multimedia environment, to examine the relative effects of two types of multimedia learning on science achievement and attitude towards science learning and to investigate the effects of treatment and students' learning ability. The results of this study were summarized as follows: 1. On science achievement; The multimedia learnings were more effective than the traditional one. Difference between multimedia learning I (through individualistic learning) and multimedia learning II(through peer interaction) was not significant. There was not interaction effect of treatment and students' learning ability. 2. On attitude towards science learning; The multimedia learnings were more effective than the traditional one. The multimedia learning I (through individualistic learning) was more effective than the multimedia learning II (through peer interaction). There was no interaction of treatment and students' learning ability. 3. On students' perceptions on multimedia learning; The students in the multimedia classes showed the multimedia learning were good in causing interest. making students absorbed in studies, and giving many learning materials, but not good in a couple of points such as making students bored and not explaining in detail.
