본 연구는 디지털 콘텐츠의 불법복제와 관련하여 이에 영향을 미치는 다양한 요인을 분석하고자 이러한 행위가 비교적 빈번하게 발생한다고 판단되는 대학 현장에서의 불법행위에 초점을 두고 사용자의 윤리적 성향과의 상관관계를 분석하였다. 합리적 행동이론을 토대로 디지털 콘텐츠 불법복제의도, 태도, 주관적 규범, 불법복제 적발시 예상되는 처벌의 심각성 등의 연구요인을 도입하고 설문조사를 통해 연구모형의 타당성을 검증하였다. 295개 설문자료를 이용하여 가설 검증을 시도한 결과, 처벌의 심각성은 주관적 규범과 태도에 영향을 미치며, 이 두 요인은 디지털 콘텐츠 불법복제의도에 유의한 영향을 미치는 것으로 나타났다. 또한 윤리인식 설문이론을 토대로 하는 상대주의 개념을 조절변수로 설정하여 연구모형을 구성하는 계수간의 차이를 분석하고 시사점도 함께 논의하였다.

Purpose : This study is conducted to research the attitude of social workers toward withdrawing life sustaining treatment and compare and analyze the different types of their attitudes. Methods : Research design of this study is Q methodology approach. The study population is 23 social workers. Q sample to investigate the attitude of social workers toward withdrawing life sustaining treatment included 30 statements. After listening to the purpose and method of the study, the 23 social workers agreed to fill out a survey asking sociodemographic information and have been forced to be distributed in 9 scale Q-sample. Results : The collected data was processed through QUANL PC program, sorted into 3 types as followings. The first type was 'the pursuit of quality of life' that the quality of life is more important than the length of life, the second 'choosing to withdraw life sustaining treatment' that they want to write or encourage family to write advanced directive, the third 'withholding life sustaining treatment' regardless of the cost. Conclusion : In conclusion, the social workers attitudes toward withdrawing life sustaining treatment were grouped as three different types, the first type was 'the pursuit of quality of life', the second 'choosing to withdraw life sustaining treatment', the third 'withholding life sustaining treatment'.

This paper deals with a new method to derive the Generalized Jacobian Matrix of a space robot. In a conventional method to derive the Generalized Jacobian Matrix, generalized coordinates select Joint angles and a space robot body's position and attitude angle. But, in this paper, we select position and attitude angle of the end-effector or the handled floating object as generalized coordinates. Then, we can derive the Generalized Jacobian Matrix of the system which consists of several space robots and a handled floating object. Moreover control methods operated by only one space robot can be easily extended to the cases of cooperation task by several space robots. Computer simulations show that the Generalized Jacobian Matrix derived here is effective.

Purpose: This study was conducted to examine the relationship among health-related quality of life, smoking knowledge, smoking attitude, and smoking cessation intention in male smokers. Method: The subjects were 259 male smokers in J city. The data was collected using structured questionnaires from Nov. to Dec. of 2003. The data was analyzed by the SPSS (ver. 10.0)computer program, and it included descriptive statistics, t-test, ANOVA, the Pearson correlation coefficient, and Stepwise Multiple Regression. Result: The smoking cessation intention had a significant positive correlation among health-related quality of life (r=.159), smoking knowledge (r=.161), and smoking attitude (r=.127). These variables account for $26.8\%$ of smoking cessation intention. Conclusion: These results suggested that the smoking cessation program to enhance the health-related quality of life, smoking knowledge, and smoking cessation intention and to increase a negative influence on smoking attitude need to be developed. Therefore, these findings give useful information for constructing a smoking cessation program in male smokers.

The ground-based spacecraft simulator is a useful tool to realize various space missions and satellite formation flying in the future. Also, the spacecraft simulator can be used to develop and verify new control laws required by modern spacecraft applications. In this research, therefore, Hardware-in-the-loop (HIL) simulator which can be demonstrated the experimental validation of the theoretical results is designed and developed. The main components of the HIL simulator which we focused on are the thruster system to attitude control and automatic mass-balancing for elimination of gravity torques. To control the attitude of the spacecraft simulator, 8 thrusters which using the cold gas (N2) are aligned with roll, pitch and yaw axis. Also Linear actuators are applied to the HIL simulator for automatic mass balancing system to compensate for the center of mass offset from the center of rotation. Addition to the thruster control system and Linear actuators, the HIL simulator for spacecraft attitude control includes an embedded computer (Onboard PC) for simulator system control, Host PC for simulator health monitoring, command and post analysis, wireless adapter for wireless network, rate gyro sensor to measure 3-axis attitude of the simulator, inclinometer to measure horizontality and battery sets to independently supply power only for the simulator. Finally, we present some experimental results from the application of the controller on the spacecraft simulator.

Attitude and position parameter of satellite is needed in producing digital elevation model. This paper propose a method which determines the order of polynomial and initial values of satellite exteria parameters using header file of computer compatible tape. Experiments on a SPOT level 1A full science show that planimetric error is 11m and the altimetric error is about 18.3m.

The performance of a strapdown attitude reference system(SDARS) under dynamic environments was analyzed by means of computer simulation. The study is aimed toward the performance evaluation in the presence of translational or angular vibration during 20 sec of flight time. The simulation was based on the error model of rate gyro, and Euler angle algorithm was employed to compute the attitude.

This paper presents a navigation error compensation scheme for Strap-Down Inertial Navigation System(SDINS) using electro-optical sensor. The proposed scheme uses the position or the attitude information from the sensor. For each case, 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 boundedness of position and attitude errors.
