LED beacons operated on an isolated marine area are mostly employing the solar power supply system, and this system is well known for increasing the cost of management and maintenance. Recently, a number of researches and demonstrations on self-contained LED beacon is actively conducted to solve this issue. In this work, we propose an self-contained LED beacon with Bluetooth Low Energy function for an effective management of LED beacon. Firstly, control program structure is designed by expanding the status protocol of self-contained LED beacon, and then it is implemented into the form which administrator can easily understand. The control system visualizes the status and control data of self-contained LED beacon, and this enables the rapid decision-making of administrator. Also, minimizing electricity consumption of the beacon, it can transfer and update the status or light information of self-contained LED beacons with smart phone.

WBAN/USN systems are applied from the various environment. Therefore, it is coming to be important efficient use power and communication method. The present paper materialize Slave node system which get power from light energy. Also, it materialize Wake-up module and self-power-off circuit which use S-R Flip Flop for efficient using power. This system can be efficient using power at Slave node system. Also, it can be possible application of Self sustaining system by performance verification Wake-up module which determine system "on" without power and Self-power-off circuit.

Factors influencing the success or failure of information systems9IS) have been discussed in many literes. However, little thertical development or empirical research has examined effectiveness of information systems in health center. This study evaluates several model that contribute to IS success in bealth center. In this study, we propose a process model that exhibits several variables influence one after another. These can be classified into six different dimensions. These inclube system aspect, invidual effect. The system aspect is classified by system quality, information quality and service quality. On individual and organizational aspect, this study uses computer self-efficacy and support of top management. The results of this study are as follows: according to multiple regression analysis of user satisfaction, information quality and support of top management are statistically significant influence on user satisfaction. System quality and service quality are a partially significant influence on user satisfaction. Hypothesis 5, proposing that computer self-efficacy would relate positively to user satisfaction, ws not supported by the questionnaire results. Based on these results, information quality and support of top management are very important variables for IS success.

Bowlby has proposed that child-mother attachment is important in the child's representation of self. In this study the child's self-perceived competence was examined in connect8ion with child-mother attachment in a sample of 40 6-year-olds. Quality of attachment was assessed based on the child's behavior on reunion following a seperation using a system devised by Main and Cassidy. The self-perceived competence was assessed with a pictorial harter's Scale revised by Julie Lee. The results showed significant connections between attachment and the self-perceived competence. Specific areas of self-perceptions were related to particular patterns of attachment.

Over the fast few years, web-based e-Learning have made remarkable progress. According to advance of e-Learning, the evaluation of e-Learning effectiveness and success model become more important. This study had a focus on the effect of system characteristic of e-Learning systems and self-efficacy on learning performance. Data has been collected from 192 person experienced in e-Learning. The questionnaire method was adopted to collect the data for this study. The research was conducted by using SPSS 12.0 and AMOS 4.0. The research results and suggestions of the study are as follow. First of all, system quality and information quality of e-Learning system had positive relationship with perceived usefulness. Second, information quality was related positively to user satisfaction. Third, perceived usefulness was positively connected with user satisfaction. Fourth, user satisfaction and self-efficacy had relation to learning performance.

In the coming age of information warfare, information security patterns take on a more offensive than defensive stance. It is necessary to develop an active form of offensive approach to security protection in order to guard vital information infrastructures and thwart hackers. Information security products need to support an automatic response facility without human intervention in order to minimize damage to the attacked system and cope with the intrusion immediately. This paper presents an automatic intrusion response model which is developed on a Self-Extension Monitoring. It also proposes an ARTEMIS(Advanced Realtime Emergency Management and Intruder Identification System), which is designed and implemented based on the suggested model. The Self-Extension Monitoring using self-protection and replication minimizes spatial limitations on collection of monitoring information and intruder tracing. It enhances the accuracy of intrusion detection and tracing.

The following study was taken in the Seoul, Gyeonggi, Incheon, Kangwon, and Chungcheong areas to analyze the performance levels of safety management by characteristics of school foodservice. The following results were obtained from a survey conducted on 2,271 middle and high school dietitians in 808 schools. Out of the 808 schools surveyed, 513 schools (63.5%) were self-operated and 295 schools (36.5%) were managed by a contract. Regarding the performance level of the hygiene duties, contract-managed schools were rated as 4.02 points while self-operated schools were rated relatively higher (4.16 points). The self-operated schools had an average score of 3.60 points for the TQM-based HACCP system, and the areas that scored lower than the average were strategies, human resources, data and analysis. The average score of the contract-managed schools was 3.42 points, and such areas as leadership, human resources, data and analysis, and customer satisfactory level scored below the average. For the analysis of CCP performance level, the contract-managed schools scored 4.28 points while self-operated schools scored 4.34 points. Overall, the hygiene duties, CCP performance level, and TQM-based HACCP system performance of the contracted schools were lower than those of the self-operated schools. Therefore, it is advised that the contract-managed schools consider new measures to strengthen their performance level for improved safety of school foodservice.

This paper introduces rule-based reasoning (RBR) based self-recovery system for network fault in ubiquitous computing. This system is fault management system for fault recovery of rule-based for self-recovery in ubiquitous computing environment. We proposed rules of network fault recovery applied the system as a distinguished reason of network fault. And, in this paper, the network fault self-recovery system proved the rules that applied each situatpion through the simulation.

Self-Prevention Plan Review Report and Review Standards Process Safety Management(PSM), Safety Management System(SMS), including the contents of the safety management system audit standards, notices and guidelines on the screening form and were analyzed. Were expected through the interview and screening personnel in the screening process to identify problems prior research so that it can be reflected in the. Also divided into methods such as document review and on-site implementation status of the review written Emergency Preparedness Plan depending on the item proposed. Toxic Chemicals Control Act(TCCA) Self-Prevention Plan Review Regulations. However, the substantial approval process, and do not enable the system performance lacked Self-Prevention Plan Review. Review half configuration to enhance the professionalism and efficiency of the work of this research was performed.
