To estimate accurate design quantiles considering statistical characteristics of hydrological data is one of the most important procedures in the design of hydraulic structures. While at-site frequency analysis estimates design quantile using observed data at a site of interest, regional frequency analysis (RFA) utilizes a number of sites included in a hydrologically homogeneous region. Therefore, RFA could provide a more accurate design quantile at ungauged site or sites with short observation period. In this review article, RFA is classified into stationary RFA and nonstationary RFA depending on the characteristic of hydrological data, and the basic concept, procedure, and application of each technique are explained in detail focused on the index flood method. Additionally, a review of the state of the art for RFA procedure is presented. This paper is finalized by describing the stationary regional rainfall frequency analysis over South Korea contained in the amendment of "Standard guidelines for design flood estimation" and various future study topics related to nonstationary RFA.

This paper presents an assessment method of the ground vibration level with a combination of measured data and an analytic method. The basic concept of the method is similar to that in FRA(Federal Railway Administration) manual for detailed vibration analyses. However, going into detail, the assessment method was modified for a feasible evaluation of the vibration reduction effects of diverse types of wave barriers. The force density was evaluated in a vehicle-track interaction analysis and the transfer mobility of vibration was analyzed through a 2-D ground vibration analysis. The calculated 2-D transfer mobility was corrected to incorporate transfer characteristics of actual ground vibration by comparing the previously measured data and analysis results. Nine types of vibration reduction effects of wave barriers were analyzed on a shallow tunnel section of an urban railway where numerous civil complaints had actually been filed.

This study investigated the perception of science philosophy education targeting 150 elementary school teachers in metropolitan cities and provinces. The questionnaire survey on the perception of the philosophy of science education was composed of a 5-point Likert scale based on the interest and experience of the philosophy of science, the reason for difficulty in using it, and the introduction method, the expected effect. As a result of the survey, elementary school teachers' awareness of the interest and necessity of the philosophy of science was generally high, while the experience of learning and teaching the philosophy of science was low. In addition, to the reason why it was difficult to utilize the philosophy of science, teachers answered that there was insufficient teacher training and development of teaching and learning methods. As a way to introduce the philosophy of science in science education, it was thought that it was necessary to combine the concept learning and inquiry method, and elementary school teachers' perception of the expected effect of using the philosophy of science was generally high. The results of this study are meaningful in that they provide basic data on the direction of the introduction of the philosophy of science in elementary science education.

Purpose: This study identified the planning trends for formal and informal learning spaces in the college of medicine through literature reviews. And then, by the analysis of the actual condition of existing domestic facilities, It was organized the architectural planning baseline data and future directions for the formal and informal learning spaces in the college of medicine. Methods: This study was conducted using literature reviews on the existing medical education method and learning space planning. Subsequently on-site surveys and questionnaires were conducted at existing facilities. Results: In the past, learning space of the college of medicine was considered only a formal learning space such lecture rooms, labs. But lately it has been turned into a total learning concept that embraces shared learning spaces such as libraries, student spaces, amenities and common spaces such as lobbies and hallways. ① Formal learning spaces are composed of teaching and practice areas. Since It is the basic functions that comprise the college of medicine, this paper conducted a functional analysis based on the current operating system of the College of Medicine and provided baseline data on architectural planning such as function, layout, zoning, and detailed planning. ② The informal learning sharing space was divided into a library area and a student well-being and convenience area to analyze the real conditions of domestic medical college. In addition, by comparing the trends and differences in foreign medical colleges identified by literature analysis, this paper summarizes the need to revitalize informal learning spaces and their integration into formal learning spaces, architectural planning considerations, etc. Implications: the evolution of the learning method and the flexibility of the learning space bring about changes in the learning space.

This study aims to provide basic resources for the construction of the archives on the official family service history in Korea. The study collected records of family policies and official family service from 1948 to 2019 and thereafter attempted to classify the official family service. In addition, experts were consulted to diagnose compliance with research contents and directions, investigate priorities of the family policies, and provide opinions on the elements of each process of archiving. The results of this study were as follows. First, there were five areas of concern to be considered in the process of establishing an archive of official family services: concept, scope, collection, arrangement, preservation, and utilization. Second, the findings suggest which processes are critical to developing a sustainable and systematic archive system for the official family service history. The construction of the archives will provide a platform for understanding the contents of integrated family policies and inform the direction of future family policies in Korea. In addition, these archives will be an important factor in building a solid Korean national identity.

Objectives: This study is to analyze Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) and to consider the direction of development. Methods: This study focuses on Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) that Five Phase Theory(五行學說) has been applied as a compound and it is designated Five Phase-Five Transport Points-Acupuncture Method(FPT Acupuncture Method, 五行五輸穴鍼法). Principles, Acupuncture Points(經穴), standards of diagnosis and treatment subjects of FPT Acupuncture Methods used in practices of Korean Medicine (韓醫學) were analyzed through updated literature. Next, the theoretical issues of FPT Acupuncture Methods regarding the composition of selecting exclusively on Five Transport Points(五輸穴) and targeted treatment subjects were investigated. Based upon the investigation, the future direction of development was studied. Results & Conclusions: Firstly, pattern identification and treatment of FPT Acupuncture Methods targeted mostly on Viscera and Bowels(臟腑). However, some showed the tendency to Five Phases Reductionism(五行 還元主義) which attempts to apply Five Phase Theory(五行學說) to symptoms that were not related to Viscera and Bowels(臟腑). Secondly, Five Transport Points(五輸穴) are theoretically related to 'Viscera and Bowels in Concept of Visceral Manifestation(臟象臟腑)'. Thirdly, when the cause of the symptoms exceeds the main therapeutic range of FPT Acupuncture Methods, it is effective to add Acupuncture Points(經穴) excluding Five Transport Points(五輸穴). And also, it is efficient to use Acupuncture Methods(鍼法) that is not based on principles of Five Phase Theory(五行學說). For the accomplishment, further researches on the approaches to apply basic Korean Medical principles such as Three Yin and Three Yang(三陰三陽) into Acupuncture Methods(鍼法) and Acupuncture Points(經穴) are necessary.

As IoT systems such as smart farms and smart cities become popular, a large amount of data collected from many sensor nodes is sent to a server in the Internet, which causes network traffic explosion, delay in delivery, and increase of server's workload. To solve these problems, the concept of fog computing has been proposed to store data between IoT systems and servers. In this study, we implemented a software platform of the fog node and applied it to the prototype smart farm system in order to check whether the problems listed above can be solved when using the fog node. When the fog node is used, the time taken to control an IoT device is lower than the response time of the existing IoT device-server case. We confirmed that it can also solve the problem of the Internet traffic explosion and the workload increase in the server. We also showed that the intelligent control of IoT system is feasible by having the data visualization in the server and real time remote control, emergency notification in the fog node as well as data storage which is the basic capability of the fog node.
