This paper presents a vehicle control algorithm for Personal Rapid Transit (PRT) system. PRT system is a one-way direction network system which is composed of guideway branches, merging/diverging points. Vehicle control algorithm can be divided into two kinds. Those are merging control algorithm and the other. We emphasized on the merging control algorithm. For that, we first devised a front/virtual front vehicle finding strategies. Properly determined front/virtual front vehicle is the starting point of vehicle control. The objects of merging control are to avoid collision and to pass the merging point fluently. Which implies that jerk constraint and limits of acceleration and deceleration etc. are should be considered. To verify the validation of the vehicle algorithm, we executed simulations and presented test results.

In this paper, we propose the intelligent robot control technique for mobile robot using personal digital assistants (PDA). With the proposed technique, the mobile rebot can trace human at regular intervals by the remote control method with PDA. The mobile robot can recognize the distances between it and human whom the robot must follow with both multi-ultrasonic sensors and PC-camera and then, can inference the direction and velocity of itself to keep the given regular distances. In the first place, the mobile robot acquires the information about circumstances using ultrasonic sensor and PC-camera then secondly, transmits the data to PDA using wireless LAN communication. Finally, PDA recognizes the status of circumstances using the fuzzy logic and neural network and gives the command to mobile robot again.

Purpose: The purpose of this study was to examine the relationships between treatment belief, personal control, depressive mood, and health-related quality of life in patients with hemodialysis based on self-regulation theory. Methods: Data were collected from 220 patients at 27 local hemodialysis clinics in Seoul during 2013 and 2014. The Revised Illness Perception Questionnaire, the Hospital Anxiety and Depression Scale, and Medical Outcomes Study Short Form-12 were used to measure outcome variables. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson correlation, and multiple regression using the 'enter' method. Results: Treatment belief and personal control scored 3.58 and 3.54 out of 5 points respectively, on average. Treatment belief and personal control of kidney disease were negatively correlated with depressive mood and positively correlated with health-related quality of life. According to the regression analysis, treatment belief, monthly income, and personal control were discovered to account for 21.8% of the variance in depressive mood, where as depressive mood, monthly income, treatment belief, and age were found out to account for 40.6% of the variance in health-related quality of life. Conclusion: Our study demonstrated significant positive relationships between treatment belief and illness outcome in hemodialysis patients. Interventions aimed to provide the necessary information and trust to maximize the effectiveness of treatment need be developed to improve patients outcomes.

This study aims to examine the impact of characteristics of SNS content provided by airlines on customer satisfaction and to explore the effect of the personal characteristics of the customers which have a modulating effect on the relationship between content characteristics of SNS and customer satisfaction. The data were collected over a period of April 21. 2019. to July 21. 2019. for three months from the people who have experience using SNS provided by airlines. 225 samples were selected and used as final samples from a collection rate of 93.4 percent. Findings suggest that the characteristics of airline's SNS content which include a promotion, information, and communication showed a positive impact on customer satisfaction. The analysis of a modulating effect of individual characteristics on the relationship between the airline's SNS content characteristics showed that diversity pursuit propensity, innovation propensity, and information-seeking propensity control the relationship between characteristics of airline's SNS content which are publicity, information and customer satisfaction. And it was found that all three personal characteristics do not control the relationship between communication and customer satisfaction. Thus, airlines should use SNS more effectively to generate customer satisfaction and present marketing measures to help generate profits through consumer purchasing behavior. It is expected that the findings of this study will help airlines to utilize marketing implications for effective and practical marketing methods.

Recently, internal information leaks is increasing rapidly by internal employees and authorized outsourcing personnel. In this paper, we propose a method to integrate internal control systems like system access control system and Digital Rights Managements and so on through expansion model of SIEM(Security Information Event Management system). this model performs a analysis step of security event link type and validation process. It develops unit scenarios to react illegal acts for personal information processing system and acts to bypass the internal security system through 5W1H view. It has a feature that derives systematic integration scenarios by integrating unit scenarios. we integrated internal control systems like access control system and Digital Rights Managements and so on through expansion model of Security Information Event Management system to defend leakage of internal information and customer information. We compared existing defense system with the case of the expansion model construction. It shows that expanding SIEM was more effectively.

Radio Frequency IDentification (RFID) is a method of remotely storing and retrieving data using small and inexpensive devices called RFID tags. In this paper we propose a proxy agent framework that uses a personal device for privacy enforcement and increased protection against eavesdropping, impersonation and cloning attacks. Using the proxy model a user decides when and where information carried in a tag will be released. In particular, the user can put tags under her/his control, authenticated requests, release tags, transfer them to new owners, and so on. In this paper, we analyses a new type of simple a framework for enhancing RFID security by means of a proxy, a personal device that assumes control of a user's tags.
