Electronic commerce has provided another access for consumers to purchase products, but some researches have pointed out that there are difficulties for companies to do business on web. For lack of trust, many people not prefer purchasing through virtual channels. Based on the literature review, this study aims at empirically testing the impact of website design on individual trust in internet firms. From statistic analysis, we will conclude that security, interaction, and navigation functionality will affect on-line trust.

This paper deal with a method for calculating the continuity of Korea Augmentation Satellite System (KASS), which was completed in Korea in December 2023, and a plan to respond in the event that a continuity hazard situation occurs during operation. For this purpose, the International Civil Aviation Organization (ICAO) Satellite Based Augmentation System (SBAS) continuity standards, Wide Area Augmentation System (WAAS), and European Geostationary Navigation Overlay Service (EGNOS) continuity cases are examined in this paper. According to the measures recommended by the ICAO, when the number of continuity risks exceeds a certain level and the level drops drastically, various mitigation operations by country are implemented. Through this, if KASS does not meet ICAO continuity standards in the future, such measures can be referred to. In addition, this paper computes the short-term KASS continuity during the test broadcast period. Although continuity does not meet the ICAO standards, although this test period is too short, further meaningful analysis in the future is required. Additionally, this paper carried out an analysis of the timing and period to systematically calculate the meaningful value of continuity.

The Ministry of Maritime affairs and Fisheries embarked on Oct. 8, 1996, incorporating most of the previously fragmented maritime administrations into one single institution. But the maritime administrative functions related to safety and security missions have not yet been merged into a synergetic whole, with versatile multi-functional systems working so effectively that better services to the public might be excepted. Enhancing administrative capabilities to meet future demands with limited resources requires that these missions be integrated into one institution and an enterprising management system be adopted to overcome bureaupathologies, such as complacency and inertness of administration.

Various kinds of performances and events have been held by local governments along with the worldwide popularity of K-pop, and there is a growing concern about possible accidents. Actually, a large-scale of accident took place during the MBC pop song concert in Sangju Sports Stadium in October 3, 2005. And another great safety accident occurred during an open event in the Lotte World in Seoul in March 26, 2006. The purpose of this study is to propose improvement of security company that carry out security activity through the analysis of the cases of accidents and common causes in the event sites. The improvement of safety management for large-scale event site by the study are as followings; First, institutional measures should be taken to extend the size of private security companies. Second, more education and training should be provided for security personnels who work for the event. Third, private security companies should prepare for the security measures more thoroughly in advance. Fourth, private security companies should make every possible effort to maintain order in the event site. Fifth, private security companies should bolster their collaboration with relevant organizations. Sixth, security companies should take actions to make themselves completely ready for any possible unexpected situations.

The detection sensitivity of a Walk Through Metal Detector (WTMD) currently being developed and operated in Korea differs from one manufacturer to another, making it difficult for them to be used based on Aviation Security level. In addition, the FAA 3-GUN Test approved by the domestic aviation authority for aviation security supervision is a single test object. There is no Operational Test Piece (OTP) consisting of multiple test objects for the operation of aviation security for a WTMD. This paper, the detection sensitivity of a WTMD applied by a commercial OTP was measured and detection sensitivity standards for a WTMD were developed based on results of measurement. Furthermore, institutional plans to maintain the same detection sensitivity for domestic aviation security were made through suggestions for Korean standards OTP development methods, taking characteristics of the aviation field into consideration.

It has been long time since the social concern about school safety was fully raised in our country. The accidents, such as sexual violence against young children, traffic accident when going to and from school, psychological violence by bullying, extorting money & violence and so on, frequently happen. Under the circumstances that this kind of school safety problems are concerned greatly by society, it is very important for schools to create the environment in which children can have a safe living. The study focuses on the necessity and introduction of a professional school police system to establish the sexual violence prevention system in advance. The system, practically and systematically organized, can prevent various kinds of safety accidents and form the agreement of family, regional society, and related institutions alike. It is also supposed to emphasize the strengthening of school safety by its operation.

With the application of digital technology to safety-critical infrastructures, cyber-attacks have emerged as one of the new dangerous threats. In safety-critical infrastructures such as a nuclear power plant (NPP), a cyber-attack could have serious consequences by initiating dangerous events or rendering important safety systems unavailable. Since a cyber-attack is conducted intentionally, numerous possible cases should be considered for developing a cyber security system, such as the attack paths, methods, and potential target systems. Therefore, prior to developing a risk-informed cyber security strategy, the importance of cyber-attacks and significant critical digital assets (CDAs) should be analyzed. In this work, an importance analysis method for cyber-attacks on an NPP was proposed using the probabilistic safety assessment (PSA) method. To develop an importance analysis framework for cyber-attacks, possible cyber-attacks were identified with failure modes, and a PSA model for cyber-attacks was developed. For case studies, the quantitative evaluations of cyber-attack scenarios were performed using the proposed method. By using quantitative importance of cyber-attacks and identifying significant CDAs that must be defended against cyber-attacks, it is possible to develop an efficient and reliable defense strategy against cyber-attacks on NPPs.

Troublesome problems are being caused by hallucinogenic drugs which come not only from illegal narcotics but also from unprohibited general drug-kinds such as cough-remedy agents of textromerupan, namely, Lamina, Rubi-king and the likes. Abuse and misuse of narcotics permeated into and threatens mental health of socially-known peoples, actor, actress, talents and businessmen as well. This study especially dealt with problems related with Mesampetamin, Rurajaepam, Texstrometropan and Karisofrodol which affects mental behaviour, and considered counter-measures through analysis and developed appropriate system of goods circulation for guidance to be complied by the medicine professionalists. The guidance sought here is recommended to the government ministries for further enforcement of crack-down of the drug crimes. Arquesa in method is recommend as a method of identifying behaviors and facial expressions of abusers and misusers of narcotics at the spot in place. This study is directed to curtailing hallucinogenic drugs use for absolute preventive security by detecting out black dealers of narcotics supplying to the abusers and misusers. There is a need of special education program to cut off the flow of narcotics or drugs crimes into official security force as well as private security personnel. This study introduced a priority and emphasis of real augmentation to theory and practice of the modern scientific security which can protect the mental health of the guarded persons as well especially in the light of security safety curriculum at the school.

As society develops, the demand for safety and security services increases. Developed nations such as the United States use advanced technology to lower crime rate and promote intelligent security services. First, this article examines intelligent systems that are used for monitoring and detecting crimes and dangerous situations. Recently, we have been studying technologies that enable preemptive responses through prediction of crime and hazardous situations. In this paper, we examine the cases of security services based on a crime/risk prediction model and explain the structure and major technologies of an intelligent security system. In addition, we propose a direction for technological development for achieving future security services.
