  • Most governments have an interest in unused energy, because of high oil price and climate change. Particularly, it is very important to urban governments which have less renewable energy than other local governments. So Seoul, the capital of Korea, established a plan for the development of unused energy in 2007. But it has some problems related to the feasibility of this plan. So this paper checked and reviewed the economic feasibility of unused energy development cases in four cities by using three sub elements: technology, infrastructure, institution. As a result, it discovered that these urban governments have technological feasibility because they are located near big river or ocean. And they used the existing infrastructure and received the institutional subsidies from central governments in order to increase the economic feasibility of unused energy development projects. In conclusion, local governments of Korea have to try to seek how they can utilize the existing infrastructure for unused energy development in the situation that there are few institutional supports from the central government.

  • In recent years, the relationships and inter-dependencies between the countries in East Asia have deepened, and the vision for regional cohesion such as the East Asian Community have been gradually elaborated. A Grand Design for Northeast Asia is one of these comprehensive visions that aim to improve and develop international infrastructure through cooperation in the field of transportation, energy, environment, and information technology. This study paid attention to the possibility for a system for regional cohesion and cooperation in spatial development in East Asia, and analyzed the roles of the ESDP according to the requirements of the East Asian situation. As a result, it was understood that while the development of infrastructure is a main stream in the case of the regional cohesion in East Asia, the cooperative visions for the conservation of natural and cultural heritage, which are being positioned as an important policy in the EU, have not been seen. It is a very important subject to promote the policy cohesion/cooperation on the conservation and management of natural/cultural heritage and the development of tourism infrastructure for the sustainable development of East Asia, considering the trends in the growth of the interchange population and tourism market in East Asia. It was discussed that the role of research networks like the International Landscape Architectural Symposium of Korea, China and Japan is becoming important in supporting this policy cohesion and in grasping the present conditions and trends of the spatial development of these counties.

  • Recently, operation of highway is the complex digital Infrastructure based on complicated IT. The application of IT is increasing more and more in digital Infrastructure. Though IT is very convenient, if unpredicted operating risk of highway occurs, widespread damage can be large. When operating risk of highway occurs, road users are out of smoothly-run service because of the operating interruption. This risk causes unpredicted operating management cost and additional maintenance cost. It will excess over the planned operating cost, which may leads to users's unsafety and operator's insolvency because of income loss. Until now, related studies to find out the risk are not sufficient. The purpose of this study is to suggest risk cost items and to estimate the reasonable risk cost by using simulation method in case of occurring the huge power failure at the operating digitalized highway. This study indicates the several plans to hedge against risk cost and the management of highway project. From now on, it will be used as basic data to confirm the soundness of operating system in Digital Infrastructure.

  • Objectives: The objective of this study was to investigate the relationship between the level of Electronic Medical Record (EMR) system adoption and healthcare information technology (IT) infrastructure. Methods: Both survey and various healthcare administrative datasets in Korea were used. The survey was conducted during the period from June 13 to September 25, 2017. The chief information officers of hospitals were respondents. Among them, 257 general hospitals and 273 small hospitals were analyzed. A logistic regression analysis was conducted using the SAS program. Results: The odds of having full EMR systems in general hospitals statistically significantly increased as the number of IT department staff members increased (odds ratio [OR] = 1.058, confidence interval [CI], 1.003-1.115; p = 0.038). The odds of having full EMR systems was significantly higher for small hospitals that had an IT department than those of small hospitals with no IT department (OR = 1.325; CI, 1.150-1.525; p < 0.001). Full EMR system adoption had a positive relationship with IT infrastructure in both general hospitals and small hospitals, which was statistically significant in small hospitals. The odds of having full EMR systems for small hospitals increased as IT infrastructure increased after controlling the covariates (OR = 1.527; CI, 1.317-4.135; p = 0.004). Conclusions: This study verified that full EMR adoption was closely associated with IT infrastructure, such as organizational structure, human resources, and various IT subsystems. This finding suggests that political support related to these areas is indeed necessary for the fast dispersion of EMR systems into the healthcare industry.

  • Nuclear infrastructure systems play an important role in national security. The functions and missions of nuclear infrastructure systems are vital to government, businesses, society and citizen's lives. It is crucial to design nuclear infrastructure for scalability, reliability and robustness. To do this, we can use machine learning, which is a state of the art technology used in various fields ranging from voice recognition, Internet of Things (IoT) device management and autonomous vehicles. In this paper, we propose to design and develop a machine learning algorithm to perform predictive maintenance of nuclear infrastructure. Support vector machine and logistic regression algorithms will be used to perform the prediction. These machine learning techniques have been used to explore and compare rare events that could occur in nuclear infrastructure. As per our literature review, support vector machines provide better performance metrics. In this paper, we have performed parameter optimization for both algorithms mentioned. Existing research has been done in conditions with a great volume of data, but this paper presents a novel approach to correlate nuclear infrastructure data samples where the density of probability is very low. This paper also identifies the respective motivations and distinguishes between benefits and drawbacks of the selected machine learning algorithms.
