One of the most important paradigms in society has recently been a set of efforts to prepare for the future and to protect the environment by saving carbon that occurs in everyday life as well as in the industry. In order to successfully deal with this new paradigm, Korean government has adopted and implemented various policies including the green certification, the development of green technologies and green growth. Many agencies and organizations in both public and private sectors have established plans about the carbon savings and performed a lot of research using IT technology. For example, attempts have been made in Korea to use as electronic documents instead of paper documents using these green IT and mobile devices. This paper proposes a 'Paperless' waiting order count system using QR code and mobile phone as an example of green IT for 'Low carbon and Green growth'.

Elevators, an important vertical means of transportation used daily, have enriched the city into a state-of-the-art giant skyscraper forest. The purpose of this study is to analyze problems about elevator safety and present engineering and legal improvement measures. The research method adopted the important engineering elements that make up elevator safety and the elevator safety law and the method of analyzing the papers already studied. Based on his experience as a policy advisor to the Korea Elevator Safety Authority, he analyzed the problems of the related statutes, focusing on the construction, electrical, electronic, information and communication, and the elevator safety law, which comprise the elevator safety system. As a result of the research, it was suggested that the so-called legal engineering system should be established through the convergence of laws and disciplines related to elevator safety. This study is expected to be an alternative to establishing an engineering and legal convergence system for elevator safety in the future.

Machine learning and artificial intelligence are core technologies for the 4th industrial revolution. However, it is difficult for the general public to get familiar with those technologies because most people lack programming ability. Thus, we developed a Graphic User Interface(GUI) to overcome this obstacle. We adopted TensorFlow and used .Net of Microsoft for the develop. With this new GUI, users can manage data, apply algorithms, and run machine learning without coding ability. We hope that this development will be used as a basis for developing artificial intelligence in various fields.

This study attempted to investigate an efficient human resources management plan by enhancing organizational performance and reducing the factors which influence turnover intention after analyzing the effects of job burnout on organizational effectiveness and turnover intention. To test a research model, after explaining the purpose of the study to them at work, data were obtained through a standardized questionnaire survey. To figure out the effects of job burnout on organizational effectiveness and turnover intention, causality was analyzed using the Structural Equation Model (SEM). According to hypothesis testing, a total of five hypotheses were chosen, and the following results were obtained: Job burnout had a significant effect on organizational commitment (-0.456), job satisfaction (-0.488) and turnover intention (0.501). In terms of relations between organizational effectiveness and turnover intention, organizational commitment (-0.350) and job satisfaction (-0.199) decreased turnover intention. Therefore, it is important to discover and analyze these obstacles which hinder employees from being absorbed in their work with attachment.

The dedicated line linked up with the internet maintains generally the efficiency of network by using Best Effort Model. But it is the problem that we allocate the higher bandwidth to services which request high bandwidth regardless of service types or purposes. To overcome this weak point, we use the Session QoS System which distinguish between business services such as E-mail, Web, etc. and non-business services. But, a recent session QoS system is not adequate to the environment similar to university, because that has many users who have various requests. In this paper, to satisfy various requirements of many user's in session QoS system which support services of research, education, business, etc., we analyze types of service in the environment of education and research network and propose a necessity of management strategies of session Qos system.

Recently, the most important paradigm is to prepare future and to protect the environment through the carbon savings occurs in everyday life and whole industry. For the success of this new paradigm, Korean government encourages the green certification and the development of green technologies and green growth as one of the important policies are adopted and implemented. Public agencies and companies establish the plans about the carbon savings and implement a lot of research has moved on using IT technology. There are some attempts in Korea to use as an electronic document instead of the use of paper document using these green IT and mobile devices. In this paper, the waiting sequence system using mobile phone is proposed as an example of practical engineering education for 'Low carbon, Green growth'.

Technology standard continues to exist as an social agreement throughout all industry. With development of Information and Communication, it is recently considered as a strategic factor for enhancing interoperability and increasing market dominance. Hence, technology standard research(standardization research) have a significance in analyzing the process of standard adoption and its economic effect and deriving theoretical and policy implications. However, as existing relative researches are lack in consideration on indigenous value of technology and its interoperability, there exists limitation in drawing the result of technology centered analysis. The goal of this study is to suggest new technology centered standard method by implying function of technology differentiation rate and technology preference that are deduced by technology network analysis into two stage game theory. As an example of empirical case, we selected wireless pan technology of Internet of Things, and derive its technological structure and implications related to standard.

Over the past 20 years, brain science has developed rapidly thanks to new technologies such as functional magnetic resonance imaging (fMRI), leading to more accurate knowledge of human nature and behavioral changes. This knowledge is also actively applied in the field of management. This research aimed to gain insights into how neuroscience can be incorporated into management through the case of Midas IT Co. This construction software company has a separate organization with the purpose of studying brain science, and it makes and implements human resource management policies based on brain science. The founder Lee Hyung-woo has a humanist management philosophy, and the company's brain science research supports that philosophy. The case study method was adopted as the research method, and procedures such as interviews and direct observation, participation observation, and document information were carried out. The company's human resource management system can be explained by a brain science model called "SCARF", which combines various neuroscience discoveries. As this model suggests, the company has improved the trust and satisfaction of its members by reducing threat of status and by increasing certainty, autonomy, relationship, and fairness in the workplace, resulting in the creation of a platform for creativity, integrity, and high performance.

This paper analyzes the effects of population aging on regional differentiation from the New Economic Geography perspective. The addition of old-age population variable affects the price index, income, nominal wage, and real wage derived in the short-run equilibrium. Using the new model, we can better explain industrial agglomeration patterns corresponding to the new long-run equilibrium. As the real wage criterion does not properly take the old-age group into account, we employ the indirect utility function as an additional condition for equilibrium. We further consider tax as a policy tool for achieving a better long-run equilibrium. This would enable the government to direct the economy toward a particular equilibrium desired in the face of population aging.
