This study aimed to asses the relationship between shoppers' security need sufficiency and customer satisfaction on the quality of security services in Shopping Mall. This study gathered data from 485 citizen in five shopping centres at KyungKi areas. Collected data was analysed by factor analysis, reliability analysis, path analysis and multiple regression analysis with SPSS WIN 16.0. The results of the study yielded the following four perspectives. First, secure equipment and the service quality of security officers in the shopping malls have a decisive effect on customers psychological stability and crime prevention. Second, they are a strong influence upon customer satisfaction and operational security. Especially, the professionalism of the staff has a marked effect. Third, the service quality of security officers and secure equipment in the malls have an effect on operational security services and efficiency of secure services. Finally, this dissertation showed that the quality of secure equipment services and officers' mild In summary, the conclusion of this study is that secure equipment service, officers' mild manner and professionalism of the security officers affect the customer satisfaction measurement directly. They also affect customer satisfaction through psychological stability and the prevention of crime indirectly. In other words, the good quality of security in the shopping centres affects the using of facilities definitely.

This study identified the cause-and-effect relationship of security management service quality by empirically analyzing whether the performance factors affecting the casino industry are improved when the quality of the security management service is improved. For this, Partial Least Squares (PLS) that can deduce the structural relationship between variables was used. To verify the representativeness of the population, SPSS 19.0 was utilized in a demographic analysis, a independent T-test and Scheffe test. The analysis of the data revealed that the casino industry must preferentially manage assurance, empathy, and security to improve the casino security management service quality, and that, of these, security was the most important factor. To help improve service quality, a theoretical and empirical basis that can consider the importance and priority of individual factors was presented based on the result of this analysis. It also revealed that the security management service is an essential factor for stable business activities of casinos. Further, the importance of the role of the security management service in business strategy formulation for improving the industry performance was recognized through the study results. A service quality improvement method was provided by focusing on the factors that must be preferentially considered for service quality improvement; moreover, implications that can predict the results of such method were presented.

The purpose of this study was aimed to identify the relationship between service quality and behavior by spectators participating security exhibition. The subject for this study was spectators who participating World Security Expo 2014 held three days from March 12 to 14 in 2014. 350 samples were selected by convenience sampling for subject of this study. 320 out of 350 surveys, excluded 30 unfaithful and defected surveys, were used for data analysis. Research tool was questionnaire which was based on and recomposed by previous researches home and abroad. The collected data were treated for analysis of frequency, reliability, factor analysis, correlation, and multitiple regression analysis by using SPSS statistic package version of 18.0 Through the above research method and procedure, the results were as followings. First, the relationship between service quality and behavior after participating exhibition appeared positively. It was found that there was high relationship between service quality and behavior. Second, analyzing relationship of factors between service quality and behaviors resulted to effect perceived environment, human services, and product on word of mouth. Third, analyzing relationship of factors between service quality and behaviors resulted to effect perceived environment, product, and price on re-participation.

In this paper We focuses on suggestion to quality model for IoT infrastructure services for Internet of Things. Quality model is suggested on security set out in ISO25000 quality factors and assessment of the existing traditional software application of ISO 9126 quality model. We validated that the proposed model can be realized it was applied to evaluate the 4 elements and related security in Metrics.

미국 국립표준원(NIST), 전기전자공학회(IEEE) 등의 주도로 진행중인 스마트그리드 프로젝트에서는 미래 전력시스템을 위한 통신망으로 인터넷 기반의 단일화된 통신망을 유력한 후보로 검토하고 있다. 인터넷기반의 전력통신망은 최선노력서비스(best-effort-service)를 기본으로 하기 때문에 종단간 지연을 보장할 수 없으며 패킷 손실이 발생할수 있다. 따라서 기존 전력통신망이 보장해주던 높은 통신 품질과 보안성을 보장해주지 못한다. 본 논문에서는 현재 그리고 미래의 전력관련통신서비스가 인터넷 기반의 통합망에서 사용가능한지 검증하여 본다. 이를 위해 현재의 전력시스템에서 사용되는 통신 서비스들로부터 품질, 보안성 동의 요구조건을 도출하고 이를 바탕으로 스마트그리드 환경에서 추가 될 통신 서비스들이 미래 인터넷 기반통합망에서 사용가능한지를 검증하여 본다. 마지막으로 현재 인터넷 기술로 만족하지 못한 요구조건을 수용하기 위한 해결방안을 제시한다.

The purpose of this study is to verify how much the education service quality related to physical security of security department students affects college life satisfaction and academic continuation decision. To this end, a survey was conducted from April 10 to 28, 2023 targeting 200 university students receiving physical security education at the university. The survey contents were composed by dividing the variables into "first, educational service quality, second, college life satisfaction and third, academic continuation decision," and based on this, 3 research hypotheses were selected. We calculated regression analysis to examine the study model. Analysis result, among the 3 research hypotheses, "Educational service quality ⇨ College life satisfaction, College life satisfaction ⇨ Academic continuation decision" was significantly calculated and adopted, but "Education service quality ⇨ Academic continuation decision" was found to be insignificant and rejected. According to the results of a survey conducted among students, it seems that students will have the academic continuation decision only when they are college life satisfaction.

Because websites contain personal information such as address, contact information, etc., Attention about website security is required. This research is a study to examine that user's security awareness has a moderating effect on the relationship between website quality factors and trust, information and service value on websites holding personal information. As a result of questionnaire survey of the secondary school students and parents 635 people, website quality factors excluding usability positively affected trust of the website. Information quality on the website had a positive influence on service value and service value also affected trust. User's security awareness about the website has a moderating effect on the relationship between information and service value. The result of this research means that users are not continuously using websites with a low security level. Based on the results of this research, we presented theoretical and practical suggestions for the stakeholders of websites.

광대역 통합망(BcN: Broadband convergence Network)에서 대역폭의 증가와 서비스의 통합으로 보안의 중요성이 빠르게 증가하고 있다. 그러므로 보안은 BcN에서 다루어져야 할 중요한 문제의 하나로 인식되어야 한다. BcN과 같은 QoS-aware 통신시스템에서 사용자는 원하는 서비스 품질 수준의 보장을 위하여 여러 가지의 서비스 클래스 중에서 선택할 수 있다. 그러나 보안은 아직 이런 QoS 구조에서 하나의 파라미터로 인정되지 않고 있으며, 보안-관련 서비스 클래스도 정의된 바 없다. 본고에서는 BcN 구조에서 발생할 수 있는 보안 취약성을 분석하고 BcN 인프라 정보보호를 위하여 관련 기술, 표준화, 국내 동향 등에 대하여 기술하고자 한다.

According to ISO/IEC 9000, quality to satisfy users' requirements when using the product or service is defined as the characteristics of the synthesized concept. Secure web application coding information systems with the reliability and quality of service is one of the determining factor. Secure coding in order to achieve the quality based on the model is necessary. The reason is that the security is in quality properties in the range of non-functional requirements that necessitates. Secure coding for the design of quality systems based on the quality of the definition of quality attributes, quality requirements, quality attribute scenarios are defined, and must be set. To this end, referring to IEEE 1061 quality model for web application, quality model structure is developed. Secure web application architecture design is composed of coding quality of the model systems, web applications draw interest to stakeholders, decision drivers secure coding architecture, quality attributes, eliciting quality requirements of the security settings, creating web application architecture descriptions and security framework.
