A railway security detection system is very important. There are many safety factors that directly affect the safe operation of trains. Security detection technology can be divided into passive and active approaches. In this paper, we will first survey the railway security systems and compare them. We will also propose a subway security detection system with computer vision technology, which can detect three kinds of problems: the spark problem, the obstacle problem, and the lost screw problem. The spark and obstacle detection methods are unique in our system. In our experiment using about 900 input test images, we obtained about a 99.8% performance in F- measure for the spark detection problem, and about 94.7% for the obstacle detection problem.

This research addressed the issue of how mothers' representations of attachment are transmitted to children, focusing on post-infancy attachment and on maternal stress as a mediator between mother's attachment style and child attachment security. Fifty-three mother-child dyads participated in a lab visit when the children were 30 months (T1) and 49 months (T2) of age. The Attachment Style Questionnaire and the Parental Stress Inventory were used to measure mothers' characteristics; the Separation-Reunion procedure and classification at T1 and the Attachment Q-set at T2 were used to measure children's attachment security. The models were analyzed by Analysis of Moment Structure Equation. Results confirmed evidence that no direct pathway exists between maternal attachment style and child attachment security : at T1 child attachment security formation was related to maternal stress, but there was no such relationship at T2.

Industrial Security is a management activity protecting industrial asset of enterprise by application of security elements(physical, IP, conversion security tools) and can be understood as a comprehensive term including software aspect(establishment of policy and strategy, maintenance operation, post- response act, etc.) as well as the operation of hardware elements. In this paper, after recognizing the definition and relative concept of industrial security, the role and its relative laws of the industrial security organizations, the management system and the reality, I will find some problems and submit a reform measure. Furthermore I would like to propose the policy direction to enhance the national competitiveness and to become one of the advanced nations in 21st industrial security through the effective industrial security activities of our enterprises.

The development of ICT has led positive aspects such as popularization of Internet. It, on the other hand, is causing a negative aspect, Cyber Terror. Although the causes for recent and continuous increase of cyber security incidents are various such as lack of technical and institutional security measure, the main cause which threatens the cyber security is the users' lack of awareness and attitude. The purpose of this study is the positive analysis of how the personal and job characteristics influence the cyber security training participation rate and the response ability to cyber terror response training with a sample case of K-corporation employees. In this paper, the relationship among career, gender, department, whether he/she is a cyber security specialist, whether he/she is a regular employee), "ratio of cyber security training courses during recent three years", "ratio that he/she has opened the malicious email in cyber terror response training during recent three years", "response index of virus active-x installation (higher index means poorer response)" is closely examined. Moreover, based on the examination result, the practical and political implications regarding K-corporation's cyber security courses and cyber terror response training are studied.

Current paradigm of industrial security is changing into the effective operation and management from simple establishment of security equipments. If the physical security system(entry control system, video security system, etc.) and the IT integrated security control system are conversed, it makes us possible to prevent, disrupt and track afterwards the insider's information leakage through the risk and security management of enterprise. That is, Without the additional expansion of the existing physical security and IT security manpower, the establishment of systematic conversion security management process in a short time is possible and can be expected the effective operation of professional organization system at all times. Now it is needed to build up integrated security management system as an individual technique including the security event collection and integrated management, the post connected tracking management in the case of security accident, the pattern definition and real time observation of information leakage and security violation, the rapid judgement and response/measure to the attempt of information leakage and security violation, the establishment of security policy by stages and systematically and conversion security.

In this study, we developed a comprehensive model to measure the National Information Security Level based on PRM framework. The proposed model reflected a rapidly changing technology environments such as social network service, mobile devices, and etc. This new model consists of three layers:Infrastructure Layer, the Action Layer and the Performance Layer, and there are 16 sub-indexes under the 3 layers. To develop new model and sub-indexes for measuring the National Information Security Level, much amounts of documents related to security indexes or deliberation criteria and security guidelines from international organization were reviewed and then most probable index pool were composed. The Index pool were verified by expert group consisting of professors and specialists. Through five times of screening and having an evaluation review, 16 sub-indexes were deduced and then Delphi and AHP have been conducted to obtain validity and objectiveness of the indexes. Thus the new proposed national information security index will show more exact national information security level and we expect that the indexes give much implications for establishing information protection policy.

This study aims to develop an index of food security in order to assess food security status in Korea and to evaluate reliability and validity of the index. The index of food security was developed based on the US Household Food Security Survey Module (US-HFSS). After the US-HFSS was translated and back-translated, it was evaluated and modified by a focus interview for experts. The developed Korean Household Food Security Survey Module (K-HFSS) was tested by cognitive interviews and a pretest for general community population to assess its application for Korean population. For the reliability and validity of K-HFSS, the survey was conducted with 300 adults aged 40 years or more living in a rural community and 212 infants and toddlers living in an urban community. The reliability was assessed by Cronbach' alpha and the validity was evaluated by content validity, construct validity, and criterion-related validity. The questionnaire items of K-HFSS were partly modified, accounting for Korean social and cultural backgrounds and adapted by general community population. The reliability was relatively high, showing Cronbach' alpha coefficients ranged from 0.80 (for adults) to 0.87 (for infants and toddlers). The content and construct validities were all acceptable. The result of criterion-related validity showed that food security status was significantly related to the household income level. In conclusion, the K-HFSS would be used as a reliable and valid instrument to assess food security status in parts of the Korean population.

A secured building where only approved personnel can access is sometimes not secured because of the lack of recognition of security. Unapproved personnel enter and access freely to the internal system of the building, and this makes security risks. In order to deal with these problems, the existing entrance-control system had developed by using the RFID card certification and the infrared sensor to measure distance. However, it is difficult for the system to guarantee security due to the weakness of each method. Therefore, this study aimed at providing a new method of guaranteeing security by comparing the double entrance-control system and the existing entrance-control system.
