We are living in the age of information and the role of information communication is large. Moreover, the mass commucatioin and the concentration of communication facilities could cause a significant impact on the lives of the people in the event of an accident. Therefore, we proposed improvement measures by analyzing the standard manual of risk management for information communication disaster. The disaster management agency should improve the management system, the related law system, the basic planning and response system, and the standard manual for risk management through continuous research into the statute and the standard manual for risk management.

This paper analyzes the outcomes surveying 79 firms in Korea to investigate how Information Technology(IT) Outsourcing risk factors affects IT Outsourcing intention. Based on our literature reviews based on number of key articles, journals, and the focus group interviews, IT Outsourcing risk factor s are proposed into three different domains: Transaction, Client, Vendor perspectives. As the statistic al analysis, it found that the risk factors related on the client, vendor perspectives, is closely related to the IT Outsourcing intention of the Korean firms. So It will be desirable to prepare and resist the risk factors of clients of themselves and IT service vendor's for the adopting and enlarging the IT outsourcing implementation.

As the modern society becoms industry acceleration and urbanization. Disaster is noticed that loss of life and a huge property loss. In sprit of continuous experience misfortune that reality have nonhigh national consciousness. But government is on the brink of various disaster. Various disaster are becoming larger and larger through industrialization and abnormal climate. The researchers of the study suggest as followers: the selection of a key risk factors throuh vulnerability analysis and risk assessment of disaster. As well suggest as policy direction throuh plan of personalized safety management.

This study focused on university students' risk perception of cybercrime through media exposure. For this purpose, I tried to figure out the results of risk perception on cybercrime with 8 factors. As a result, the lowest type of cybercrime was internet fraud, and it was caused by media type and degree of exposure, where university students get information about cybercrime. There's a difference of students' risk perception by media type, news media was the best. Depending on the media of the environment, even in the area of cyber crime there is a difference of perception of risk for each individual. And it can be confirmed that the risk perception in response to the exposure of the media has changed.

The applications of computers and communication system and network technologies in nuclear power plants have expanded recently. This application of digital technologies to the instrumentation and control systems of nuclear power plants brings with it the cyber security concerns similar to other critical infrastructures. Cyber security risk assessments for digital instrumentation and control systems have become more crucial in the development of new systems and in the operation of existing systems. Although the instrumentation and control systems of nuclear power plants are similar to industrial control systems, the former have specifications that differ from the latter in terms of architecture and function, in order to satisfy nuclear safety requirements, which need different methods for the application of cyber security risk assessment. In this paper, the characteristics of nuclear power plant instrumentation and control systems are described, and the considerations needed when conducting cyber security risk assessments in accordance with the lifecycle process of instrumentation and control systems are discussed. For cyber security risk assessments of instrumentation and control systems, the activities and considerations necessary for assessments during the system design phase or component design and equipment supply phase are presented in the following 6 steps: 1) System Identification and Cyber Security Modeling, 2) Asset and Impact Analysis, 3) Threat Analysis, 4) Vulnerability Analysis, 5) Security Control Design, and 6) Penetration test. The results from an application of the method to a digital reactor protection system are described.

All of smart phone users not always make a good use of mobile shopping. The main cause is that in case of non-user of mobile shopping, potential apprehension to psychological and security weakness affects building up resistance on mobile shopping. In this paper, we designed models of innovation resistance heavily based on literature reviews and previous studies, and tried to find how perceived risk affects consumer's purchase intention in mobile shopping process. In conclusion, it shows that security, one of psychological factors, affects perceived risk in all aspects, while negative influence of society and cognitive dissonance just affect social risk and delivery risk, and uncertainty also just affects performance risk. Besides, it shows that all of variables made up perceived risk affects resistance of purchase. Especially social risk turns out to be a most influential factor to purchase behavior through smart phone.

Digital vessels can occur large a disaster at sea because vessels in fire and collision in case of certain unforeseen circumstances. In this paper, We propose digital vessel context monitoring system through risk analysis. We propose environment information analysis system using wireless sensor that have to acquire marine environment and context of marine digital vessel. For conducting simulation, we chose 300 data sets to train the neural network. As a result, we obtained about 96% accuracy for fire risk context and we obtained 88.7% accuracy for body of vessel risk context. To improve the accuracy of the system, we implement a FEC (Forward Error Correction) block. We implemented digital vessel context monitoring system that transmitted to diagnosis result in CDMA.

Background: The purpose of this systematic review was to investigate the effects of digital therapeutics for insomnia on sleep disorders and mental health improvement compared to the control group. Methods: Following the guidelines on systematic review(PRISMA, NECA), a literature search was conducted through PubMed, Cochrane Library, EMBASE, RISS, KISS, and KoreaMed using keywords. The Cochrane Risk of Bias Tool and Review Manager version 5.3 were used for risk of bias and effect size assessment. Results: Thirty eight RCT met criteria for inclusion. When compared against three control conditions, the digital therapeutics for insomnia was an effective intervention for improvement sleep disorders and mental health in comparison to waiting list and Patient-directed care with some intervention by medical staff. However, digital therapeutics for insomnia were no more effective than face-to-face CBT-I control group. Conclusion: The efficacy of digital therapeutics for insomnia was evaluated differently depending on the control group. Therefore, in phase 3 clinical trials for efficacy evaluation, it is necessary to review whether the control group has been properly established.

Recently, safety accidents of daily necessities such as humidifier disinfectant, mobile phones, and infant diapers, have occurred frequently. To protect consumers from these accidents, product safety management is required, and a product risk assessment tool is needed to evaluate the degree of safety of the product. In this paper, we have constructed RAS, which is a system that can evaluate product risk based on injury information of product accident in Korea Consumer Agency. RAS consists of an injury information analysis system for analyzing accident-related information and a risk assessment system for assessing risk using information derived from the system. The Bayesian network - based probabilistic method is applied to reflect the causal relationships that affect product risk in the risk assessment process. We used RAS to evaluate 33 children's products and compared them with the results of EU RAPEX RAG. Subsequent tasks include reducing the subjectivity of the input of the accident impact scale, and linking the above two systems.
