In this study, a new strategy is presented to transmit the fundamental elastic beam problem into the modern optimization platform and solve it by using artificial intelligence (AI) tools. As a practical example, deflection of Euler-Bernoulli beam is mathematically formulated by 2nd-order ordinary differential equations (ODEs) in accordance to the classical beam theory. This fundamental engineer problem is then transmitted from classic formulation to its artificial-intelligence presentation where the behavior of the beam is simulated by using neural networks (NNs). The supervised training strategy is employed in the developed NNs implemented in the heuristic optimization algorithms as the fitness function. Different evolutionary optimization tools such as genetic algorithm (GA) and particle swarm optimization (PSO) are used to solve this non-linear optimization problem. The step-by-step procedure of the proposed method is presented in the form of a practical flowchart. The results indicate that the proposed method of using AI toolsin solving beam ODEs can efficiently lead to accurate solutions with low computational costs, and should prove useful to solve more complex practical applications.

The trend of the web is moving from portal-centered to user-centered, and RIA(rich internet application) is considered best solution for usability and functionality of the next generation web. But the lack of reference document or technical guide for RIA implementation is a big obstacle for extension of RIA environment to practical business engineer or user. In this paper, I will suggest the implementation conceptand reference site for user-centered environment based on RIA concept. The suggested concept support wire/wireless environment, and use the e-mail that is already used by many company or portal. The contents of this paper will be very helpful to the practical engineer or portal/company that want to use or implement about RIA environment.

GNTECH-ICEE, which this study seeks to investigate and evaluate, demonstrates a new system of training innovative engineers. An essential component of this operation is a Small Engineering Group (SEG) that links professors, students and industrial experts together, to study and apply different techniques in determining the processes and products that relate industrial sectors needs. As an education program, SEG also provides a right direction for educating students, and generates industry-university link based human resources. Through these efforts, GNTECH-ICEE has effectively trained creative, professional, and practical engineers, by operating a variety of programs for meeting industrial needs and enhancing engineering education. SEG has many merits that have influenced its success so far, but the program also faces some challenges. The merits include; strong group bondage, practical ability incubation, and efficient administrative support. In terms of demerits, it is evident that sufficient theoretical education and local small-middle size enterprises (SMEs)' sustainable participation cannot be warranted. Thus, we propose that initiative strategies have been helpful to maximize GNTECH-ICEE's goal of making students into multi-player engineer, but continuously financial and administrative strategies be put into place in order to guarantee SMEs' long-term devotion to the program, and to help create a sustainable network between students and the companies involved.

This research started from the premise that Jacques Perret, "Savoyard gentleman" of the 17th century - whose only legacy consists of Des fortifications et artifices, a book of fortified town designs - is still an elusive figure in the history of architecture and deserves to be further investigated. In particular, attention needs to be paid to the lack of any attempt by scholars to define his actual professional status and cultural background: was he an architect, an engineer, a professional or an amateur? The intention of this paper is therefore to shed some light on this question by examining selected contents of his book describing five projects of fortified towns. Plates and descriptions are carefully analyzed related to the engineering (defensive structures) and architectural (city layouts, buildings) content. The figure that emerges is that of an articulate personality who does not fit either in the architectural or in the military engineering professional world. In the field of engineering, he simultaneously demonstrated the competence of a professional and the na$\ddot{i}$vety of an immature technician, while in the field of architecture he showed an advanced creativity alongside several technical and theoretical misunderstandings. From the analysis in this study, the assumption is formulated that Jacques Perret was a connoisseur, i.e. an erudite without any direct involvement in real professional activity. This work is intended to provide a hypothesis for further researches that, hopefully, will deepen our understanding of several other aspects of Perret's complex identity and work.

Professional Engineers for Building Electrical Facility is required to have both theoretical background and field experiences as an expert for managing a building electrical facility. In order to cultivate many Professional Engineers with both theoretical and practical basis, it is necessary to analyze the past examinations and develop an efficient cultivating plan. In this work, we analyzed the tendency of past and recent 4 year's examinations and the relation of examinations to the university curriculum. We suggest some methods that supplement the gap between curriculums of universities and qualification tests. Also, this paper introduces some advanced education programs of the reeducation agencies for these areas.

This paper examines the life and achievements of Lillian E. Gilbreth(l878-1972) called 'the first lady of American engineering' as an attempt to excavate women engineers in history. Lillian changed her majors from English literature to psychology of management through her marriage, and tried to integrate psychology of management and scientific management by coworking with her husband. After that, Lillian contributed to extend scientific management to the domain of domestic labor, institutionalize industrial engineering in American universities and enhance the status of woman in engineering societies by her own independent research and education. The success factors of Lillian Gilbreth as a woman engineer includes the development of professional career by conquest of various social discrimination, the positive understanding and assistance by neighborhood males, the selection of an emerging field like industrial engineering, and so on. This study can provide not only a case of role model for women engineers but also practical reference materials for gender-sensitive engineering education.

PBL is a student-centered pedagogy in which students learn about a subject through the experience of problem solving. Marine engineer is the expert which supports the safe navigation and solves the problems could happen in independent situation as a ship. This study executed the fundamental study on the maritime training education for marine engineers using PBL. In this study, we conducted the survey on 56 students for 6 months using PBL in H university. The result showed the improvement on ability to solve the problems, interpersonal relationship, communication skill, synthetic thinking faculty and practical use of data but some students answered the complaint of the insufficient information and unacquainted learning method of PBL. This suggested the development and improvement plans for the maritime training education using PBL based on this fundamental study.

The effect of earthquake induced torsion, due to mass eccentricities, is investigated with the objective of providing practical design guidelines for minimizing the torsional response of building structures. Current code provisions recommend performing three dimensional static or dynamic analyses, which involve shifting the centers of the floor masses from their nominal positions to what is called an accidental eccentricity. This procedure however may significantly increase the design cost of multistory buildings, due to the numerous possible spatial combinations of mass eccentricities and it is doubtful whether such a cost would be justifiable. This paper addresses this issue on a theoretical basis and investigates the torsional response of asymmetric multistory buildings in relation to their behavior when all floor masses lie on the same vertical line. This approach provides an insight on the overall seismic response of buildings and reveals how the torsional response of a structure is influenced by an arbitrary spatial combination of mass eccentricities. It also provides practical guidelines of how a structural configuration may be designed to sustain minor torsion, which is the main objective of any practicing engineer. A parametric study is presented on 9-story common building types having a mixed-type lateral load resisting system (frames, walls, coupled wall bents) and representative heightwise variations of accidental eccentricities.

This study aims to give suggestions based on survey to improve the quality of Global Construction Engineer Training Program in line with the government goals. The domestic construction industry in Korea has kept shrinking, whereas the global construction market is forecasted to keep expanding in the future. It has become an urgent task to be taken up for construction contractors and engineering firms so as to improve their capacity, in particular, in the fields of planning, management, finance as well as engineering. To deal with the lack of capacity of the domestic engineers and to help them emerge as global players in the competitive overseas construction market, the Ministry of Land, Infrastructure and Transport of the Korean government has designed a program called 'Global Construction Engineer Training Program.' The eligible target of the training program is mid-career professionals who are working for the construction contractors or engineering firms. To draw suggestions for this program, an importance-satisfaction analysis is conducted to evaluate the effectiveness of the training program implemented by the S University. The S University, along with C University, was selected as an implementation organization of the program in 2014 by the government. Through an email survey, the participating students in the program were asked questions on the importance and satisfaction against 17 indicators classified into 5 categories: instruction method, professional knowledge of instructors, contents of program, curriculum, and facility and environment. The survey results show that students are satisfied with the overall quality of the program, but it was also found that they want the program opens more coursework on practical application of knowledge, case studies, and global networking.

Asian Journal of Innovation and Policy (AJIP) would like to introduce an interview section on innovations, innovators, and entrepreneurs if possible in every issue. The interviews introduced will be selected not based on a journalistic view, but rather by its theoretical or practical implications. This issue will introduce an entrepreneur who was a key engineer, Chief Technology Officer (CTO), and CEO of Samsung Electronics, in addition to being the Minister of ICT in the Korean government. Currently, he is the CEO of an investment company. His success was tied to the success of semiconductors at Samsung Electronics, which became the world leader, leading some to even call him "the god of semiconductors". This interview resurrects the debates on the mode 2 society and the role of education in entrepreneurship.
