The demand for rare-earth elements (REEs) is increasing owing to their significance as prominent materials in electronics, high-tech industries, geological research, nuclear forensics, and environmental monitoring. In general, the utilization of REEs in various applications requires the use of chromatographic techniques to separate individual elements. However, REEs have similar physicochemical properties, which makes them difficult to separate. Recently, several studies have examined the separation of REEs using LN resin as the stationary phase and aqueous nitric acid and hydrochloric acid solutions as eluents. Using this method, light REEs have been separated using dilute acid solutions as the eluent, whereas heavy REEs are separated using solutions with high acid concentrations. To increase the separation resolution between different REEs, either the column length or resin size is changed. In addition, the suggested methods are implemented to decrease the analysis time. This review presents technical information on the chromatographic separation of REEs using the LN resin and discusses the optimal experimental conditions.

The current electricity networks will undergo profound changes in the years to come to be able to meet the growing demand for electricity, while minimizing the costs of consumers and producers, etc. The electricity network of tomorrow or even the intelligent « Smart Grids » network will be the convergence of two networks: the electricity network and the telecommunications network. In this context falls our work which aims to study the impact of the integration of energy decentralization into the electricity network. In this sense, we have implemented a new smart grid model where several coexisting suppliers can exchange information with consumers in real time. In addition, a new approach to energy distribution optimization has been developed. The simulation results prove the effectiveness of this approach in improving energy exchange and minimizing consumer purchase costs and line losses.

Aids to Navigation (AtoN) is an important tool for safe navigation, and the variety of information provided by AtoN is invaluable. The demand for standardized AtoN information for efficient utilization is gradually increasing, and for this purpose, the International Association of Lighthouse Authorities (IALA) has developed S-201, a standard for the management of AtoN information, and recommends its application to member countries. Notably, since Korea defines AtoNs and manages the information according to the Aids to Navigation Act, the need for definition and information management according to the S-201 standard, an international standard, is even greater. Therefore, in this study, according to the recommendation of IALA, we aimed to suggest a way to manage AtoN information by applying the S-201 standard. To this end, after comparing the classification criteria of the AtoN information of the IALA, and that of Korea's classification standards, Korea's AtoN information management plan applying the S-201 standard was presented. The results of this study provide important basic data for managing standardized digital AtoN information that is easy to use worldwide.

In order to meet current AEC(Architecture, Engineering, Construction) industrial demand, BIM related NCS(National Competency Standards)'s study module in architectural design and construction has been created and it has been applied into the NCS-based curriculum of Specialized High Schools and Meister High Schools from March 2016. Therefore, the goal of this study is to identify the limitations BIM education in the Specialized High School and to find out the improvement plan for activation. Analysis of previous research literature and current education curriculums in the Specialized High School, and questionnaire survey of related teachers have been conducted. Finally, this paper investigated the case of BIM education in 'S' Technical High School where BIM education is carried out. This paper suggests the following three points in conclusion: 1) Updated curriculum reflecting NCS and industrial demand is necessary, 2) Continuing BIM education for teachers and financial support is necessary to get the qualified teaching capacity, 3) Curriculum reflecting BIM's possibilities needs to be developed across the interdisciplinary subjects to maximize its effect.

Along with the increasing demand for automatic and mechanical tunnel excavation methods in Korea, the Tunnel Boring Machine (TBM) method of tunnel excavation has become increasingly popular. However, in spite of this rising demand, few studies have been performed on the TBM method, in Korea. For this reason, this study focused on evaluation of the applicability of TBM performance prediction models based on field data in order to contribute to the basic and essential parts of TBM designation and the TBM method of tunnel excavation in Korea. These rock properties can be defined as the mechanical and physical factors of rock that have an influence on a disc cutter's ability to cut rock, and provide information for the evaluation of the applicability of field data. Based on outcomes from these tests, applicability of the prediction model was evaluated and the predicted performance of a TBM was compared with real field data obtained from four different TBM construction sites in Korea.

He report a systematic method which is useful for the information analysis on technology trends and market status and the construction of analyzed contents for analyzed contents for nanotechnology(NT). For the selection of key subjects, we first surveyed the preliminary demand for items and asked for the opinions of an advisory committee, and implemented the analysis on information and technology trends jointly with internal and external experts. As a result of this study, not only a theoretical method for information analysis is presented, but also a database for the analysis contents is constructed by applying this method. Eventually the national competitiveness for NT is expected to improve by providing these contents to the experts in industry, universities, research institutes and government through internet, publications and CD-ROM.

Recently, as technology development has accelerated and product life cycles have been shortened, it is necessary to derive key product features from customers in the R&D planning and evaluation stage. More companies want differentiated competitiveness by providing consumer-tailored products based on big data and artificial intelligence technology. To achieve this, the need to correctly grasp the required quality, which is a requirement of consumers, is increasing. However, the existing methods are centered on suppliers or domain experts, so there is a gap from the actual perspective of consumers. In other words, product attributes were defined by suppliers or field experts, but this may not consider consumers' actual perspective. Accordingly, the demand for deriving the product's main attributes through reviews containing consumers' perspectives has recently increased. Therefore, we propose a review data analysis-based required quality methodology containing customer requirements. Specifically, a pre-training language model with a good understanding of Korean reviews was established, consumer intent was correctly identified, and key contents were extracted from the review through a combination of KeyBERT and topic modeling to derive the required quality for each product. RevBERT, a Korean review domain-specific pre-training language model, was established through further pre-training. By comparing the existing pre-training language model KcBERT, we confirmed that RevBERT had a deeper understanding of customer reviews. In addition, all processes other than that of selecting the required quality were linked to the automation process, resulting in the automation of deriving the required quality based on data.

The purpose of this study was to propose ways to improve the library field practice of Department of Library and Information Science to improve the field environment and educational content, enhance students' field practice, increase efficiency, and increase students' satisfaction. To this end, a survey and interview survey were conducted on students who were going to do field training, and the results are as follows. First, students were well aware of what preparations should be made at school before going to field training. Second, students showed high awareness of their rights guarantees and requests for action in the event of problems at field training institutions. Third, students showed a high demand that field training should guarantee the minimum hourly wage. What is an issue in this regard is that policies that can satisfy both the burden of universities for continuous student guidance and evaluation, the burden of training institutions to conduct education while paying practical expenses, and the rights of students to be protected. This study was aimed at students, but it seems that realistic field practice policies should be presented from various angles as research on government ministries or university authorities is added.
