As the technology advances, the product design process is also being complicated. These days, it is common for engineers to consider socio-psychological factors as well as technological elements in the design process. In this work, I will explain why and how engineers make allowances for human factors in developing and designing technological products.

Network security should be first considered in a distributed computing environment with frequent information interchange through internet. Clear classification is needed for information users should protect and for information open outside. Basically proper encrypted database system should be constructed for information security, and security policy should be planned for each site. This paper describes access control, user authentication, and User Security and Encryption technology for the construction of database security system from network users. We propose model of network encrypted database security system for combining these elements through the analysis of operational and technological elements. Systematic combination of operational and technological elements with proposed model can construct encrypted database security system secured from unauthorized users in distributed computing environment.

Korean technological innovation is characterized by large firm-leading and characterized sector such as electricity and electronics. We examine the relationship between two elements. Using patent data registered at USPTO by Korean firms, We examine the relationship between patterns of innovative activities and sectoral specialization. As a result, Korean technological innovation is characterized by relatively high asymmetry, big share of large firms, high stability of ranking of innovators and diminishing role of newcomer, therefore as close as Schumpeter Mark II. But technological specialization is associated positively with the big share of large firms, negatively with low stability of ranking of innovators. It means that Korean technological innovation is led by large firms, but quantitative growth and technological specialization is achieved through competition between them.

The purpose of this study is to derive implications for the design of the next curriculum by analyzing the textbooks designed as a new subject in the 2015 revised curriculum. In the mathematics curriculum documents of , 'related learning elements' are presented instead of 'learning elements'. 'Related learning elements' are defined as mathematical concepts or principles that can be used in the context of artificial intelligence, but there are no specific restrictions on the amount and scope of dealing with 'related learning elements'. Accordingly, the aspects of 'related learning elements' reflected in the textbooks were analyzed focusing on the textbook format, the amount and scope of contents, and the ways of using technological tools. There were differences in the format of describing 'related learning elements' in the textbook by textbook and the amount and scope of handling mathematics concepts. Although similar technological tools were dealt with in each textbook so that 'related learning elements' could be used in the context of artificial intelligence, the focus was on computations and interpretation of results. In order to fully reflect the intention of the curriculum in textbooks, a systematic discussion on 'related learning elements' will be necessary. Additionally, in order for students to experience the use of mathematics in artificial intelligence, substantialized activities that can set and solve problems using technological tools should be included in textbooks.

The transformation of sector system in ICT, a prominent character in sector systems, has been paid much attention in innovation theory since Information technologies and technological environment have rapidly changed. In this context, we employ US patent data and proxy variables, measuring the basic elements for analyzing SIS and its technological characteristics in order to explore how SIS is transformed. By utilizing patent analysis, it is demonstrated that technological regimes, key links and Schumpeterian patterns of innovation have transformed drastically over last 3 decades in overall ICT sector. Consequently, our research shows clear evidence that Schumpeterian patterns of innovation have shifted from Mark I to Mark II in ICT. Our study provides a glimpse picture of dynamics of SIS since 1970 in the technological level by utilizing patent analysis.

The transformation of sector system in Information and Communications Technology (ICT), a prominent character in sector system, has been paid much attention in innovation theory with rapid change in information technologies and technological environment. In this context, we explore how Sectoral Innovation System (SIS) in ICT has been transformed since 1970 by employing US patent data and Proxy variables which measures the basic elements for SIS and its technological characteristics. By utilizing patent data, it is demonstrated that technological regimes, key links and Schumpeterian patterns of innovation in overall ICT sector have drastically transformed over the last three decades. We also reviewed how changes of knowledge bases and technological characteristics driving forces of dynamics in ICT help heterogeneous agents interact with environmental factors (Industrial structure and institutions), leading to industrial or economic growth and its dynamics in the historical perspective over ICT sector (Telecommunication, Computer and Semiconductor). Consequently, our research shows clearly that Schumpeterian patterns of innovation have shifted from Mark I to Mark II in ICT. Our study also provides a glimpse picture of dynamics patent data.

The accreditation review against engineering technological education just started in 2010. This study was conducted to get the significant implications for the accreditation of engineering technological education in Korea from the case of USA and Australia which have reviewed the engineering programs for long time. We can identify some differences between three countries. We suggested the three implications for ABEEK. First, ABEEEK needs to provide the definite graduates attributes to achieve. In that point, Stage 1 competency standard of Australia can be a good example which provide competency elements and indicators of attainment as well. Second, ABEEK needs to consult the course-embbeded evaluation for programs to check whether graduates achieve the graduates attributes. Third, ABEEK needs to benchmark the cases of USA and Australia to alleviate the paperwork load.

This qualitative research aimed to understand what leadership engineers need to have based on perceptions of people in charge of human resources in the large engineering companies in Korea. Focused group interviews were performed with 10 participants and the collected qualitative data were analyzed using the constant comparative method. The findings showed that the required leadership for engineers consists of six elements: technological professionalism, management skills, cross-functional skills, abilities to change organizational culture, work ethics, and technological creativity. This leadership elements were formulated in the engineering work environment and job characteristics which can be represented by technology-based professionalism, flexibility in work, and process-centered work. The implications for collegiate engineering leadership education were also suggested.

Among all the natural disasters, earthquakes are the most destructive calamities since they cause a plenty of injuries and economic losses leaving behind a series of signs of panic. The present study highlights the moment-curvature relationships for the structural elements such as beam and column elements and Non-Linear Static Pushover Analysis of RC frame structures since it is a very simplified procedure of non-linear static analysis. The highly popular model namely Mander's model and Kent and Park model are considered and then, seismic risk evaluation of RC building has been conducted using SAP 2000 version 17 treating uncertainty in strength as a parameter. From the obtained capacity and demand curves, the performance level of the structure has been defined. The seismic fragility curves were developed for the variations in the material strength and damage state threshold are calculated. Also the comparison of experimental and analytical results has been conducted.
