  • This Study aims to propose a new information security governance model design method for streamlining security governance at national strategic level. The research method of this study is to diagnose our operational experience and to derive a new model design method. In the meantime, national information security activities were perceived to be focused on knowledge transfer, and motivation of activities and securing of executive power were weak. As a result, security blind spots and frequent occurrence of large security incidents have become unresolved challenges. National cyber security governance should be grouped together as a whole systematically from the upper policy to the lower level of performance under the responsibility of the national leader. Based on this approach, this study presented the comprehensive framework of Korean security governance model and embodied it into four architectural designs such as vision, goal, process, and performance, thus deriving the foundation for future national governance model design. Further research is needed to diagnose problems in life cycle flow, security policies based on environmental changes, and new frameworks in which all subjects participate.

  • Human reliability analysis (HRA) is a proactive approach to model and evaluate human systematic errors, and has been extensively applied in various complicated systems. Dependence assessment among human errors plays a key role in the HRA, which relies heavily on the knowledge and experience of experts in real-world cases. Moreover, there are ofthen different types of uncertainty when experts use linguistic labels to evaluate the dependencies between human failure events. In this context, this paper aims to develop a new method based on linguistic hesitant fuzzy sets and the technique for human error rate prediction (THERP) technique to manage the dependence in HRA. This method handles the linguistic assessments given by experts according to the linguistic hesitant fuzzy sets, determines the weights of influential factors by an extended best-worst method, and confirms the degree of dependence between successive actions based on the THERP method. Finally, the effectiveness and practicality of the presented linguistic hesitant fuzzy THERP method are demonstrated through an empirical healthcare dependence analysis.

  • This study is based on parents that have preschool children of age 4~5, and analyzes the perception and parent education demand through parent experience of fire. As a result of the study about perception through parent experience about safety life, safety accidents, safety education of fire, the effect of parents' safety consciousness to fire safety life turned out to be moderate for fathers and large for mothers. The safety education method was mostly done in speaking than experience for fathers, while mothers did education through experience in daily life. Also the difficulties in safety education was lack of educating time for fathers while it was lack of knowledge and methods for mothers. Perception through parent experience of fire safety accidents showed that fathers did not have experience of fire safety accidents while mothers did. The locations perceived by parents where fires mostly occurred showed to be within home for both parents, and both administered first aid in managing fires. Perception through parent experience of fire safety education showed the importance of fire safety education to be important in both parents, and both parents had no experience in fire safety education. Also the fire safety education knowledge acquisition method was TV or the Internet for fathers, while it was participating in seminars or lectures for mothers. Fathers were moderately satisfied of the fire safety education instruction of childhood education centers, while mothers were slightly dissatisfied. For the demand of parent education about fire safety education, fathers were moderate while mothers thought it necessary of parent education necessity. The reason why parent education was needed was to be able to know immediate and prompt measures and first aid treatment in emergency situations for fathers, while it was to figure out the cause of fire safety accidents and prevent it beforehand for mothers. For the education institution of fire safety education, fathers demanded it for safety related institutions while mothers demanded it for children education institutions, and the number of times for parent education was once or twice a year for fathers while it was once a month for mothers. For the parent education instructor of fire safety education, fathers demanded safety education experts while mothers demanded infant teachers that completed the safety education course. For the fire safety education method of parent education, fathers demanded Internet searching while mothers demanded seminars or lectures.

  • Based upon mail survey method, this empirical research aims to compare the CAD education in four countries in terms of education conditions, education methods, and education performance. Results show that Korea is similar to Japan in many ways, while it differ from U.S.A. or Germany in several respects. Putting less importance in CAD course, Korean professors of CAD were found to be relatively young and deficient of teaching experience and/or industrial experience. And CAD course, which is not compulsory but elective one, is taught in a more crowded (junior) class with less satisfactory hardware and software. In the education goal or contents, the CAD courses in Korea lack real world problems or applications, concentrating less on students-based or problem-based learning methods than Germany or U.S.A.. Consequently, Korean CAD education is outperformed by German or U.S. one in educational performance both in skill improvement and in attitude enhancement.

  • Construction projects have shown a dramatic increase in size and complexity during the recent years that precise management has been recognized as one of key factors leading the project to success. It has been investigated that management in construction sites is generally done based on the experience of site engineers. Such experience based decision making lacks reliability that could bring disastrous results such as delay and cost overruns. The purpose of this study is to suggest a process progress pattern analysis method that is expected to be used as an objective reference for site managers to aid the decision making done regarding process progress management.

  • The growth of domestic fashion industry market went sluggish affected by long-term slow growth and shrinking consumer sentiment since 2012, and the entire market has shown a slight growth since 2017. Yet only some conglomerates or global businesses experience this growth. Small and medium-sized fashion companies or rising fashion designers in South Korea, face real limitations and problems poor capital, lack of professional workforce, experience, information and educational opportunity as well as difficulty of acquiring distribution network, which lead to further polarization between conglomerates and small businesses. Thus, this study proposed mobile virtual viewer system-based collaborative application prototype capable of overcoming limitations and problems drawn by analyzing business environment of domestic brands launched by rising fashion designers. Especially, through applied template-based 3D virtual fashion design technology and performing the entire process in the virtual reality beyond spatial and temporal restraints, it is assumed that more effective and efficient outcomes can be obtained compared to the previous method.

  • Purpose Recently, the tours and activities (TAA) market provided by online travel agencies (OTA) has grown rapidly and has become the third-largest in the travel industry. However, compared to its practical proliferation, TAA has not yet received much academic attention. This study aims to discuss the effect of the four domains (e.g., educational, entertainment, escapist, and esthetic experiences) of the experience economy on users' memorable tourism experiences (MTE), satisfaction, and loyalty in the context of TAA. Moreover, the study investigates how this mechanism varies depending on the tour guides' professional competency. Design/methodology/approach This study developed a research model based on the S-O-R framework. Using the survey method, data were collected from consumers who had experienced TAA offered by OTA more than once within one year. A total of 307 respondents (consumers) were used for the final analysis, and developed hypotheses were tested using a structural equation model technique. Findings The results of this study are as follows. First, educational, entertainment, and escapism experiences in the experience economy positively affect MTE. Second, within the experience economy, entertainment and esthetic experiences have a positive effect on satisfaction. Third, MTE positively influences satisfaction, repurchase intention, and recommendation intention. Fourth, satisfaction has a positive impact on repurchase and recommendation intentions. Finally, according to the level of tour guides' professional competency, there is a significant difference in the effect of escapism experience on MTE/satisfaction.
