The purposes of the study were to analyze the effects of determinants and persuasive messages on the willingness-to-pay cultural & heritage assets' admission fees. Recently visitors have responded to a nationwide boycott of the fees within national parks due to feelings of disapproval and resentment. Data were collected through onsite surveys of 302 visitors in the Mt. Gyeryong National Park. Regression analysis and two-way ANOVA were employed to obtain the results. The results indicate that credit card payment was the most prominent predictor of willingness-to-pay at the .05 level. The second highest coefficient was obtained in the condition levying of admission fees and parking fees at the same time, providing temple interpretive services, followed by free days for everyone on special days each month. In addition, the most persuasive message was the descriptive content, which stated that fees were profoundly committed to the protection of the cultural heritage for future generations. As a result, it is effective to continually persuade visitors to use posters or reminders that stress the preservation of cultural assets at the entrance gate.

According to the rapid economic growth and the escalation of recreational tourism activities due to the change of job and working patterns, currently various traffic problems often occur in tourist areas. As tourist traffic, contrary to general traffic, is not regional but rather from outside the area of interest, it is hard to grasp the traffic situation surrounding the tourist area. Furthermore, since the traffic is concentrated during a limited tourist season, it is difficult to examine and solve the problem. In this study, in order to test the feasibility of introducing a traffic transfer system to reduce congestion in tourist areas, the authors considered the differences in traffic congestion between typical and tourist seasons and designed a willingness to pay model. The willingness to pay amount for a shuttle bus fare is assumed as 1,430 Won and 1,650 Won is assumed for a transfer parking charge. These amounts were slightly above the current bus fare in the study area, but many people thought that the introduction of a traffic transfer system would help to relieve the traffic congestion approaching the tourist area and to develop tourism resources. As the willingness to pay appeared high from the persons used in this study, it was indirectly confirmed that the introduction of a traffic transfer system would be a step in the right direction.

As the popularity of single-person media content increases, We investigated the causal relationship between perceived value and intention to recommend to others. Individuality was studied on the tendency to sensation seeking and novelty seeking, which is a tendency to take boredom sensitive to monotonous and repetitive daily routines, and novelty seeking refers to new information and stimuli. The hypothesis was that high sensation seeking and high novelty seeking would perceived emotional value, epistemic value, and economic value for a single person 's media content. Hypothesis testing was performed using multiple regression analysis using SPSS21. As a result of the hypothesis test, The novelty seeking has a positive effect on emotional value, epistemic value, and economic value. Users who want to explore and enjoy new things could perceived the emotional value of having fun, fun, and sadness through single-person content, perceived a epistemic value and enjoy new information and situations as a tool to recognize new stimuli and know what they didn't know. And it could be seen that users perceive the economic value that they can enjoy at low cost or free service. The sensation seeking has a significant effect on epistemic value, but it did not affect emotional value and economic value significantly. Those who have a high tendency to sensation seeking can perceive curiosity about one-person media contents, so that they can perceive epistemic value. However, those who feel that they have not significant influence on economic value and emotional value can easily understand that expecting one's content does not feel bored by paying for a low cost or free service.

In an unmanned aerial vehicles (UAVs) system, a physical offset can be existed between the global positioning system/inertial measurement unit (GPS/IMU) sensor and the observation sensor such as a hyperspectral sensor, and a lidar sensor. As a result of the physical offset, a misalignment between each image can be occurred along with a flight direction. In particular, in a case of multi-sensor system, an observation sensor has to be replaced regularly to equip another observation sensor, and then, a high cost should be paid to acquire a calibration parameter. In this study, we establish a precise sensor model equation to apply for a multiple sensor in common and propose an independent physical offset estimation method. The proposed method consists of 3 steps. Firstly, we define an appropriate rotation matrix for our system, and an initial sensor model equation for direct-georeferencing. Next, an observation equation for the physical offset estimation is established by extracting a corresponding point between a ground control point and the observed data from a sensor. Finally, the physical offset is estimated based on the observed data, and the precise sensor model equation is established by applying the estimated parameters to the initial sensor model equation. 4 region's datasets(Jeon-ju, Incheon, Alaska, Norway) with a different latitude, longitude were compared to analyze the effects of the calibration parameter. We confirmed that a misalignment between images were adjusted after applying for the physical offset in the sensor model equation. An absolute position accuracy was analyzed in the Incheon dataset, compared to a ground control point. For the hyperspectral image, root mean square error (RMSE) for X, Y direction was calculated for 0.12 m, and for the point cloud, RMSE was calculated for 0.03 m. Furthermore, a relative position accuracy for a specific point between the adjusted point cloud and the hyperspectral images were also analyzed for 0.07 m, so we confirmed that a precise data mapping is available for an observation without a ground control point through the proposed estimation method, and we also confirmed a possibility of multi-sensor fusion. From this study, we expect that a flexible multi-sensor platform system can be operated through the independent parameter estimation method with an economic cost saving.

Entering legal management, shareholders receive some payment. We call this phenomenon the deviations from absolute priority. This study focuses on incremental effect and determinants of equity to shareholders by wealth transfer from creditors to stockholders in the process of legal management. The main results of this study can by summarized as follows. First, the incremental effect of equity to shareholders is common in the sample of this study. The sample contains 46 non-listed firms that filed for legal management and had confirmed their reorganization plans. Second, the results of the regression model analyzing the determinants of incremental equity to shareholders in legal management show that it is negative related to the solvency(total debt/total asset), firm size, and weight of claims for secured creditors and banks significantly. but corporate reorganization period(from filing to confirmation)are not significant.

In the GSM method for OWC-MIMO System, it is important to select an activation pattern set(: APS) for the performance optimization in the environment where mutual interference is high depending on the location of the transmitter and receiver. However, due to the high computational complexity, a high cost is paid in selecting the transmission APS. In this paper, we propose a method to reduce the candidate APS by pre-determining basic APS when generating candidate APS. The simulation results show that the proposed method has the same BER performance and reduce the computational complexity by 90% compared to the general GSM method in the high interfering environment.

With explosively increasing digital contents, library and Information center should have a new role between knowledge providers and knowledge users as information brokering organization. Electronic transaction system should be required for performing this brokering service since economic value is added to information and knowledge in information society. The developments and changes around library are keeping up with increasing building digital library and digitalizing printed sources. With the rapidly changing circumstances, the Internet is currently witnessing an explosive growth. By serving as a virtual information resource. the Internet can dramatically change the way business is conducted and Information is provided. However because of features o( the Internet like openness and information sharing, it has fundamental vulnerabilities in security issues. For Instance, disclosure of private information and line eavesdropping such as password, banking account, transaction data on network and so on are primary obstruction factors to activation of digital contents delivery on network. For high network security and authentication, this paper looks at smart card technologies and proposes multi-authentication protocol based on smart card on open network, implements and analyzes it.
