  • It is important to develop the smart ventilation system in order to minimize a building energy consumption using ventilation. In this study, We evaluated the efficiency of the smart ventilation system being developed at the nursery. To evaluate the energy savings and carbon dioxide removal efficiency, two kinds of experimental conditions were compared. First, air conditioner and Smart HVAC system were operated. Second, air conditioner was operating and external air was put into the inside by rate of air circulation. It was more effective when working with air conditioning and ventilation system at the same time. If the Smart HVAC system is applied in a multi-use facility, indoor air quality will be comfortable and the social cost will be reduced.

  • In this paper, we propose a real-time bus arrival notification system using deep learning to guarantee movement rights for the visually impaired. In modern society, by using location information of public transportation, users can quickly obtain information about public transportation and use public transportation easily. However, since the existing public transportation information system is a visual system, the visually impaired cannot use it. In Korea, various laws have been amended since the 'Act on the Promotion of Transportation for the Vulnerable' was enacted in June 2012 as the Act on the Movement Rights of the Blind, but the visually impaired are experiencing inconvenience in using public transportation. In particular, from the standpoint of the visually impaired, it is impossible to determine whether the bus is coming soon, is coming now, or has already arrived with the current system. In this paper, we use deep learning technology to learn bus numbers and identify upcoming bus numbers. Finally, we propose a method to notify the visually impaired by voice that the bus is coming by using TTS technology.

  • Technological innovations over the years have accentuated the workings in corporate- connected organizations and different application platforms. Hence, a unified management information system (MIS) that can utilize the Web and propel programming developments is required. Software agents, the latest developments in computer software technology, can be utilized to rapidly and effortlessly build integrated information systems. Consequently, 59 research papers on the use of software agents in MIS were identified from top 40 MIS journals published between 2007 and 2017. Then, we reviewed and classified all the research papers according to two categories: application fields and application categories. The application fields consisted of eight sub-groups: manufacturing, telecommunication systems, traffic and transportation management, information filtering and gathering, electronic commerce, business process management, entertainment, and medical care; whereas the application categories consisted of three sub-groups: multi-agent systems, personal assistants, and multi-agent simulation. The research papers were further divided into journal and year of publication, and journal and application field. The objective of our research was to understand the trend of the use software agent technology in MIS by examining the published research paper beside to add knowledge and content to the information system academic discipline.

  • This paper pointed out major problems of land use regulation policy surrounding Paldang Lake as follows: (1) inefficient management system, (2) inconsistent administrative management, (3) illogical selection of regulated area, (4) contradictory present system, and (5) controversial discharge control. Several regulation laws for the land-use surrounding Paldang Lake caused confusion of application and inefficiency of management. Amendment of regulation laws made it possible that the regulated area was developed, which resulted in the deterioration of water quality. In addition, successive regulations without scientific implementation overexpanded regulated area and focus on the discharge concentration of contaminated sources stimulated development of small size sources. To overcome these problems, we suggested reestablishment of regulated area, differentiation of regulation amendments, and flexibility in the application of regulation. It is necessary to arrange regulated area based on the efficient land use management and scientific implementation and then to mitigate land use regulation under the sustainable development. For the flexible application of regulation, it is required to amend the rule in response to the change of environmental condition and development of environmental techniques.

  • Purpose The purpose of this study is to identify the determinants of non-use and the dynamic nature of non-use by the qualitative research methodology, grounded theory methodology, as part of identifying the nature of non-use. Design/methodology/approach We applied the grounded theory methodology to a total of 23 college students, including non-users who are not currently using them, users with low intention to use them, and users with high intention to use. We extracted the codes related to the use and proposed the non-use dynamics conversion process based on the coding results. Findings First, the use of information technology can also promote the frequency of use, but can also lead to the use of negative attitudes which would fall in the state of non-use. Second, the user may have both positive and negative attitudes toward the current information technology. Third, if usage is dominated by habits, it is not so easy to change persistent use into an unused state. Fourth, factors that determine the use of specific information technology can be a factor in determining nonuse. This study has contributed to understand the essence of non - use as well as the nature of use, overcoming limitations of quantitative research approach and confirming possibility of grounded theory method in information system research.

  • The complexity of modern weapon systems using the intelligence technology demands that rapid and effective transition from force requirements to deployment and fielding. Thus this paper deals with the integration of development procedure, evolutionary acquisition, integrated test and evaluation, improvement of the requirements decision process, use of commercial products of high quality and low cost, specification deviation, and the effective use of dual use technology. In general, decision­makers, and military field users shall first consider the moving technology rapidly into use. This study is aimed to improve the defence acquisition management directive for timely force integration of weapon system.

  • This research is intended to analyze the tendency and mixed-use of the PFI for the middle schools in Chiba Province, Japan. The Ichikawa 7th middle school has included food supply system, nursery school, auditorium, day service center and care house. It consists of 2 PFIs. The one is middle school, food supply system, nursery school and Auditorium. The other is Day Service Center and Care House for elderly. This is the first mixed-use school by PFI in Japan. The PFI is a very nice tool for the future of our educational environment. But it has weak points, too. This paper analyze the case of Japanese PFI for the better results of Korean BTL systems.

  • The methodologies to develop land use plans are divided into two different ways, top-down and bottom-up planning. The bottom-up method is more efficient and effective to detailed land use planning. However, it requires considerable amount of information about the present status of land use. Cadastral information system is one of the best information provider for the planning. Building Register Database shows the type, area, use and location of a building. Both cadastral and Building Register systems apparently contain useful information needed to the physical planning. The study focuses on developing a prototype to provide real time information for detailed physical planning by a federated database system using the two databases.

  • This study is to test the applicability of QuickBird image for non-point source pollution assessment. SWAT (Soil and Water Assessment Tool) model was adopted and the model was calibrated for a stream watershed of 255.4 $km^2$ Landsat land use data. For model application with QuickBird image, a precise agricultural land use map of 1.16 $km^2$ area located in the upstream watershed was produced by field investigation. The model was run with the combination of land use and soil map scales (1:5,000, 1:25,000 and 1:50,000). The results were compared and analyzed for the contribution of non-point source pollution by the land use scale and contents.
