Purpose: The purpose of this study is to objectify the analysis results using the disaster safety awareness survey for high school students, which has been systematically and continuously educated since the Ferry Sewol disaster, and to promote educational effects by identifying the educational status. Method: The 12 questions of the disaster safety awareness survey were answered using the direct entry method on a Likert 5-point scale, and the SPSS 24 and varimax (orthogonal rotation) methods were used to establish and test research hypotheses. Result: As a result of the verification, it was found that the independent variables, knowledge competency and attitude competency, had a positive effect on the dependent variable, behavioral competency, and there was no multicollinearity, so it was verified that it was meaningful. Conclusion: As a result of the survey analysis, domestic disaster safety education showed a significant impact on the level of disaster safety awareness as an education that meets its goals. Various aspects of disasters show that the educational effect can be improved only when education is established as education by life cycle.

The life cycle of new information technologies is getting shorter, and the technologies are becoming more complex and difficult to understand. The need to better understand adoption of object orientation motivates this paper. Adoption of object orientation should certainly be influenced by prior software process technologies, such as the process-oriented structured methods, because object orientation is considered to be a paradigm shift from conventional software process technologies. This study aims to empirically analyze knowledge interference of the structured methods with object orientation. A two factorial quasi-experimental design is set forth. The period of experience using the structured methods and the period of experience using object orientation are selected as two independent variables, and the perceived ease of use is chosen as one dependent variable. Data are gathered from active members of Data Processing Management Association (DPMA), who have experiences in using both the structured methods and object orientation. The final results empirically show that previous experience using the structured methods negatively influences the perception of using object orientation that is one of critical factors to technology adoption. It is suggested here that a future study dealing with the same research topic in other countries will provide new insights about comparative studies.

For a successful construction project, the requirements of the client should be clearly defined and this should be reflected in the project based on the expertise of each project participant throughout the entire life-cycle. Therefore, it is necessary to establish the concept of Requirements Management to systematize and manage project requirements in terms of information management. This study aims to comprehensively define the concept of requirements management in the architecture industry and to provide a methodological basis for efficiently managing design requirements information by suggesting category of requirements information type and information analysis criteria. In addition, based on the case study, the requirements information was analyzed to propose a systemization methods of requirements management for PMO' design management and information management.

The artificial intelligence (AI) is a technology that will lead the future connective and intelligent era by combining with almost all industries in manufacturing and service industry. Although Korea is one of the world's leading artificial intelligence group with the United States, Japan, and Germany, but its competitiveness in terms of artificial intelligence patent is relatively low compared to others. Therefore, it is necessary to carry out quantitative analysis of artificial intelligence patents in various aspects in order to examine national competitiveness, major industries and future development directions in artificial intelligence technology. In this study, we use the IPC technology classification code to estimate the overall life cycle and the speed of development of the artificial intelligence technology. We collected patents related to artificial intelligence from 2008 to 2018, and analyze patent trends through one-dimensional statistical analysis, two-dimensional statistical analysis and network analysis. We expect that the technological trends of the artificial intelligence industry discovered from this study will be exploited to the strategies of the artificial intelligence technology and the policy making of the government.

This study was carried out to investigate the experiences of breast milk feeding information and education, breast milk feeding knowledge and attitude and needs for breast milk feeding nutrition education of high school students to encourage breast milk feeding. The subjects were 565 (male: 250, female: 315) high school students from first to third grade. The results obtained were as follows: In this survey, only 30.0% of subjects experienced breast milk feeding information and only 6.1% of subjects had breast milk feeding education. And the subjects showed the average scores of knowledge of breast milk feeding were 0.29 points of 1 point. Subjects knew well about ingredients of breast milk but they didn't know well about the physiology and method of breast milk feeding and benefits of breast milk feeding for mothers. The average scores of attitude of breast milk feeding were 3.03 points of 4 points, showed slight positive attitudes of breast milk feeding, but they had negative attitudes of emotional and practical aspects. The future plan of feeding practices was breast milk feeding 35.9% and 60.0% of formula milk feeding. A concern was that the students showed high ratio of formula milk feeding plan and they decided by incorrect knowledge of breast milk feeding. The 33.5% of students answered high school students will need breast milk feeding nutrition education, and they thought hospital faculties were the proper educators of breast milk feeding education, but dietitians were recomended as educators because of easy access at school and good knowledge of life-cycle nutrition. Therefore, to encourage breast milk feeding by mothers and supporters of breast milk feeding, breast milk feeding nutrition education is needed urgently among high school male and female students. And nutrition education programs will have to contain benefits of breast milk for babies and mothers and physiology and practical methods of breast milk feeding to improve emotional and practical attitudes for breast milk feeding. Nationwide campaign to promote breast milk feeding at public areas will be needed.

Systems Engineering(SE), as a special discipline evolved from multidisciplinary and interdisciplinary design knowledges and practical lessons learned from development practices, is required to develop today's ever-growing large complex systems. As computer speed and analytic sophistication accelerate their applications, modern society's needs have become increasingly varied and complex. Rapid advances in Systems Engineering and its education programs among the developed countries demonstrate their needs as an alternative to what is lacking from traditional disciplinary engineering to meet new challenges of our changing social environments. Systems Engineering is an interdisciplinary approach that includes both management and technical processes. Its processes, methods, and tools are used to evolve, define, and verify an integrated, life-cycle balanced set of system solution that satisfy customer needs and requirements. The process methodology offers a top-down comprehensive, iterative and recursive problem solving process which includes the stating the problems, investigating the alternatives, architecting and modeling the system, integrating and operating the system, assessing and re-evaluating the system performances. The purpose of this paper is to research the cases of SE educational programs for both domestic and other developed countries and to propose recommendations for the domestic SE educational programs in the future.

In knowledge-based economy where the human capital has an strong compatibilities, the life cycle of technologies and skills get shorter, and the mobility of labor get greater, the role of the signal system of qualifications have greater importance. This article used the KLIPS(Korean Labor Institute Panel Study) data, and analysed the factors of the acquisition of qualifications and the employment and wage effects of the acquisition of qualifications by fixed effects logit model and random effects model. The lower school stratification acquired the more qualifications, and in the case of men the unemployed one acquired the more qualifications. The employment effects of the acquisition of qualifications are significant at first year and second year in women, but the men's of the employment effects of acquisition of qualifications are not significant. The wage effects of the acquisition of qualifications are not significant. The results of the regression suggest that in Korea the signal system of qualifications do not working, and that the qualifications in Korea need to reform.

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.

Changes have occurred in the professional capabilities of the construction project managers after the global financial crisis. As representatives of construction companies and projects, construction project managers have full responsibility over a construction project. Throughout its life cycle, from design through construction to completion, the business capabilities of such managers are regarded as critical elements in the changes in the country's construction economy. Therefore, this study aimed to determine the main capabilities of current construction project managers, and to analysis of its competitiveness using Important-Performance Analysis(IPA). The results of IPA were as follows; (1)capability to win new contracts and capability to collect information of new project are needed for external relation competitiveness, (2)gerentocratic management mind-set and active breakthrough are needed for internal project management competitiveness, and (3)capability to predict issues and self-improvement are needed for self discipline competitiveness. However, this work is still considered to provide the basic data that can help Korean construction companies who plan to educate the project manager's strengthen their medium and long-term capabilities.
