Recently, earthquakes have occurred in our country and seismic stability of high-rise buildings in large cities is being a growing interest and thus the related studies have been increased. Also the grounds are considered indirectly in most of seismic designs and analyses and seismic researches based on 3D dynamic analysis are insufficient. In this study, therefore, 2D and 3D dynamic analyses were performed based on the SSI complete model including grounds and the behavior was compared and analyzed. For dynamic modeling, linear time history analyses were performed by using MIDAS GTS NX. For this purpose, a high-rise building was assumed to be constructed on top of the bedrock and surrounded by a surface layer. A sensitivity analysis was performed with the selected parameters. The dynamic behavior was compared and analyzed in terms of horizontal displacements, drift ratios, bending stresses, and weak parts. In most cases, 2D dynamic behavior was calculated to be larger than 3D's and thus it shows more conservative results with increasing number and size of weak parts.

As the Internet of Things, artificial intelligence and big data have received a lot of attention as key growth engines in the era of the fourth industrial revolution, data acquisition and utilization in mobile, automotive, robotics, manufacturing, agriculture, health care and national defense are becoming more important. Due to numerous data-based industrial changes, demand for sensor technologies is exploding, especially for intelligent sensor technologies that combine control, judgement, storage and communication functions with the sensors's own functions. Intelligent sensor technology can be defined as a convergence component technology that combines intelligent sensor units, intelligent algorithms, modules with signal processing circuits, and integrated plaform technologies. Intelligent sensor technology, which can be applied to variety of smart IT convergence services such as smart devices, smart homes, smart cars, smart factory, smart cities, and others, is evolving towards intelligent and convergence technologies that produce new high-value information through recognition, reasoning, and judgement based on artificial intelligence. As a result, development of intelligent sensor units is accelerating with strategies for miniaturization, low-power consumption and convergence, new form factor such as flexible and stretchable form, and integration of high-resolution sensor arrays. In the future, these intelligent sensor technologies will lead explosive sensor industries in the era of data-based artificial intelligence and will greatly contribute to enhancing nation's competitiveness in the global sensor market. In this report, we analyze and summarize the recent trends in intelligent sensor technologies, especially those for four core technologies.

This study attempted to investigate the changes in the perception of local government officials about agricultural infrastructure improvement projects due to the financial policy changes. A total of 141 local government officials were surveyed on the priority, the current status of the agricultural infrastructure improvement projects. Irrigation facilities renovation project and Small drainage improvement project had generally high priority, while Support project of cultivation basis for upland crops in paddy, Large scale land readjustment project, and Upland infrastructure improvement project had low priorities. After the introduction of the block grant system, agricultural infrastructure improvement projects had often been conducted by collecting opinions from local residents. The officials in charge of local governments recognized that the agricultural infrastructure improvement projects were reduced due to lack of financial resources and project potential sites. In response to the changes in the agricultural infrastructure improvement projects, most of the surveys showed that the influence of cities and provinces was strengthened. In addition, respondents most needed to improve the subsidy rate and there were a large number of cases requiring differential support to meet the characteristics of the local government. Therefore, it will be necessary to present a new perspective on the agricultural infrastructure improvement projects and to suggest differentiated projects for each regions.

Purpose: The purpose of this paper is to derive implication on the adoption of PROMs (Patient-Reported Outcome Measures) to improve quality of care in South Korea. With this purpose, the paper examines the status of PROMs in South Korea and other countries including OECD's PaRIS (Patient Reported Indicators Survey) initiative, and reviews policy cases that have adopted PROMs to improve performance of healthcare system. Methods: We conducted literature review on OECD reports on PaRIS, peer-reviewed journals, and information from the websites of relevant institutions such as ICHOM, NQF and OECD. Results: To identify healthcare services of best values and support patient-centered health system, OECD has initiated PaRIS which develops, collects and analyzes patient-reported indicators for cross-countries comparison. PaRIS is implemented on two work streams: 1) collect, validate and standardize PROMs in the areas where patient-reported indicators already exist such as breast cancers, hip and knee replacement, and mental conditions, 2) develop a new international survey on multiple chronic conditions. Countries like England, U.S., Sweden and Netherlands use PROMs for measuring performance of hospitals and performance evaluation at the national level, and provide the financial incentives for reporting PROMs. Conclusions: The use of PROMs can support the current policy agenda that is the patient-centered healthcare system which has been emphasized to reinforce the primary and the community-based care. For the use of PROMs, it is recommended to actively participate in PaRIS initiative by OECD, select appropriate instruments for PROMs, and continue on standardization of them. This will assure patients' involvement in improving health system performance, systemize information generated in the process of adopting PROMs, and develop a system to evaluate performance.

This research mainly focuses on examining the applicability of the deterministic model SLOSH (Sea, Lake and Overland Surges from Hurricanes) on Seas covering South Korea. Also, a simple bathtub approach which estimates coastal inundation area is validated as a first step of estimating effects of sea-level rise on the coastal cities of South Korea according to climate change. Firstly, the typhoon-induced surges are obtained from the model SLOSH by adopting historical typhoons MAEMI (0314) and BOLAVEN (1215). The results are compared to observational, typhoon-induced surge heights at several tidal stations. The coastal inundation area is estimated by comparing the maximum envelop of waves (MEOW) and the elevation of coastal land. It reproduces well the inundation area. It can be seen that this research gained applicability for estimating further potential coastal inundation with climate changes.

The purpose of this study is to provide a fundamental data and establish policies for the utilization of closed schools in Korea. The closed schools have been increased in Korea because not only the birth rate, and the number of students have been decreased, but also a greate number of people have moved to big cities or the elderly population is increasing. In this context, this research explores the current circumstance of Japan where experienced the similar phenomenon before Korea had. The results of this study are summarized as follows: The reason for the closed schools in Japan is a decrease in population due to the urbanization and reducing students themselves by aging. The recycling proportion of the closed schools is only approximately 62% in Japan. It means that fewer facilities have been recycled due to the transfer of the managemental departments and the lack of budgets for purchasing the closed schools. As the number of children decreases, but elderly people increases as the same time, it is necessary to positively examine the transition of the closed schools to new facilities for the elderly people. Even though the number of children had been declined, and it is recently turning back to an increasing of the residential children in 23 districts of Tokyo, there are still existing many closed schools. This phenomenon is caused by the decrease of the children and residential areas due to the aging and urbanization. For these reasons, there are many diverse demands for the practical and valuable recycling of the closed schools. However, it seems that there are few cases of successful disposal or transfer of management to other suitable ministry. Therefore, it is necessary for the closed schools to be remodeled the facilities required by current residents.
