  • 새만금 유역 내에는 다수의 보 및 제수문이 위치하고 있으며, 관개, 배수, 오염원 등이 영향을 받고 있다. 선행연구 중에는 보 및 제수문을 고려하기 위해 모형의 소스코드를 일부 수정하여 연구되고 있으나 유역모형으로 구현하기에는 한계가 있으며, 이에 대한 연구는 미흡한 실정이다. 본 연구에서는 만경강 유역을 대상으로 유역 모형과 전산유체역학 모형을 이용하여 하류 제수문에 대한 유입, 유출 그리고 오염원 등의 영향을 분석하고자 한다. SWAT (Soil and water assessment tool)은 유역 모형으로 미국 농무부에서 농업유역의 수문순환 및 비점오염원을 모의하기 위해 개발한 모형이다. CFD (Computational fluid dynamics)는 전산유체역학 모형으로 구조물을 설계하고 유체, 기체 등을 모의할 수 있다. SWAT 모형을 이용하여 농업유역 하류 제수문 위치를 출구로 지정하여 수문을 모의하고 그 결과자료는 CFD에 입력할 수 있다. CFD는 하류 제수문 구조물을 설계하고 SWAT 모형의 수문자료를 입력하여 제수문의 영향을 평가할 수 있다. 우선, 만경강 유역을 대상유역으로 선정하고 부용, 황산, 상리, 고은교 등 제수문의 위치를 파악하였다. SWAT 모형 구축을 위해 2015-2018년까지 기상, 수위, 유량 관측자료를 수집하였으며, 보정기간과 검증기간은 각 2년이며, 모형 성능 검증에 사용한 적합성 평가 지수는 R2 (Determine coefficient), RMSE (Root mean square error), 그리고 NSE (Nash-sutcliffe efficiency coefficient)를 사용하였다. 모형의 보정은 SWAT-CUP 자동보정프로그램을 사용하였으며, 모형의 보정지수는 NSE를 사용하였고, 1,000회 반복 수행을 통해 매개변수를 최적화하였다. 보정기간의 유출량 적합성 평가 지수는 R2, RMSE 그리고 NSE가 각각 0.84, 2.96 mm/day, 0.70을 나타냈다. 검증기간의 유출량 적합성 평가 지수는 R2, RMSE 그리고 NSE가 각각 0.72, 2.94 mm/day, 0.46을 나타냈다. 본 연구는 유역 차원과 구조물 차원의 모델링을 연계하는 것으로 향후 제수문 모니터링 자료를 활용하여 CFD 모형을 구축하고 유입량에 따른 제수문의 검보정 및 영향을 평가하고자 한다. 이러한 결과는 최근 기후변화에 따라 급격히 변화하는 유역환경에 대처할 수 있는 방안이 될 수 있을 것이며, 제수문 시설을 관리하는 기관에서도 합리적인 운영방안에 대한 기초자료로 기여할 수 있을 것으로 사료된다.

  • On October 31, 2023, the revision of the Medical Technologist Act made it mandatory to complete field training courses in order to obtain a license as a radiologic technologist. Therefore, we would like to survey the actual situation of field training in medical institutions to inform the revised Medical Technologist Act and propose improvement measures to increase the effectiveness of field training. A survey was conducted from March to April, 2023, among radiologic technologists working in medical institutions. The questionnaire was sent through a form on a domestic portal site, Company N, and 120 respondents completed it. Eighty-two respondents, or 68.3 percent, had experience in educating on-the-job training students. 58% of the respondents were aware of the fact that the amendment to the Act on Medical Technologist etc. made field training mandatory to obtain a radiologic technologist license. In accordance with Article 9 of the Medical Technologist Act, which prohibits unlicensed persons from practicing, 50% of the respondents were aware that those who are in training to complete an education course equivalent to the license they are seeking to obtain at a university or other institution are allowed to practice as medical Technologists. When asked what is currently taught during fieldwork, 6% of respondents said that they are required to perform radiation-generating activities in addition to observing, guiding patients, and positioning and moving patients. When asked about the future direction of education as fieldwork becomes mandatory for licensure, 77% of respondents said that they will teach more than they currently do. When asked about the appropriate total length of fieldwork, 35% said 12 weeks and 480 hours, 33% said 8 weeks and 320 hours, and 27% said 16 weeks and 640 hours. It can be seen that the current on-the-job training is inadequate according to various regulations, and students' satisfaction is low. However, with the revision of the Act on Medical Technologists, field training has become mandatory to obtain a license as a radiologist, and it is necessary to improve the educational conditions of field training. Therefore, it is necessary to comply with the Nuclear Safety Act and the Rules on the Safety Management of Diagnostic Radiation Generating Devices, introduce standardized training objectives and evaluation systems, designate training hospitals and radiologists in charge of training, and introduce extended training periods and simulation exercises to internalize field training.

  • The objective of this study is to suggest improvement plan for invention gifted education based on the awareness of teachers and professionals who related to the invention gifted education for the expansion and development of invention gifted education through improvement of relevant problems. To this end, invention gifted education system and its operational status were analyzed, and questionnaire survey on the awareness of the development plan and satisfaction level was conducted, targeting professionals related to the invention gifted education and teachers in charge of invention gifted education classes or gifted education center. The research results are as follows. First, the level of satisfaction on the invention gifted education was greater than normal (M=3.0) in general, but in the field of 'educational materials', 'teacher training programs' and 'human and material support system of support agencies', the level of satisfaction was relatively low, which requires expansion of the support. Second, it is necessary for Korean Intellectual Property Office and Korea Invention Promotion Association to designate and establish specialized research institution to play a key role in enhancing development and efficiency of invention gifted education. As a result of the questionnaire survey, it turned out that expectation and necessity of the specialized research agency was highly recognized. In particular, demand for 'research and development of gifted education method and materials' and 'research and development of teacher training materials and implementation of teacher training' was high among the key areas of the specialized research institution. Third, teachers and professionals related to the invention gifted education responded that 'invention knowledge' in the areas of invention knowledge and thinking and 'entrepreneurship' in the area of invention attitude was somewhat low toward the question on the level of the 9 characteristics of gifted students with invention talents which current beneficiaries of invention gifted education have, which leads to conclusion that review on the model for the selection of gifted children with invention talents as well as research and development of invention gifted education program to enhance characteristics with low levels is required. If long-term development plans and initiatives are deduced based on this, an effective framework for the invention gifted education will be established in the near future. In addition, it is expected that the differentiated political visions and goals will be established in connection with master plan for the promotion of gifted education.

  • Since central governments began to establish and use the Standard Records Management System(RMS) in 2007, more and more local governments and other public organizations have constructed RMS. RMS is the essential tool for records management in electronic environments, but it is not known how well the functions of RMS reflect standards and practice related records management or how many records managers use RMS in performing their works. This paper deals with analyzing the evaluation of 'classification & disposal schedule management' function in RMS. 'Classification & disposal schedule management' function has 4 subfunctions of review of classification & preservation period, management of the schedule items, assignment of classification scheme and reclassification. Classification and disposal schedule is at the heart of intellectual control of records and core area of records management. So it is important to analyze whether this function plays well a role in RMS or not. This research carried out evaluation of function and use about classification & disposal schedule management in RMS. Functional evaluation is to compare and analyze how well RMS meets the functional requirements which home and foreign standards give. Use evaluation is to investigate how records managers use RMS in accomplishing their task of managing classification & disposal schedule and to look into what is the problem with the use. This paper could get the implications through the survey of records managers who are working at central governments, regional local governments and basic local governments. And these implications are considered in institutional, functional, use and administrative aspect. It is important to communicate with stakeholders so that 'classification & disposal schedule management' function, further, all functions of the RMS in practice of records management could be used smoothly. Users of RMS have to raise demands or call for technical solutions of the problems which come up in use, while RMS developers and administrators must make more of an effort to satisfy their demands, reflect them on the RMS and enhance the system.

  • The recent phenomenon of job "Miss Match", which is inconsistent with knowledge in the demand of educational training institutes and industries, has spread to an increase in private education costs for reeducation and employment of new hires, resulting in weak individual job competency and poor employment capability, as well as economic and material waste at the national level. To compensate for these problems, the National Competency Standards(NCS), which are available immediately in practice and look for a standard point of national job competency with the aim of fostering human resources sought by industries, were developed, and even the NCS-based qualification system was launched in line with the stream of times. This study is intended to look into the importance and priority of competency units and competency unit elements at the NCS-based qualification L3 level in the skin care field for an overall check of the NCS-based qualification level at a time when educational institutes are organizing and operating the school curriculums according to the NCS and NCS-based qualification level. And it is attempted to provide basic data for the development of curriculum in fostering professional human resources required by industries. To analyze the needs for competency units and competency unit elements at the L3 level, a survey using AHP method was carried out to a group of field experts and a group of education experts. In addition, the SPSS(Statistical Package for Social Science) ver. 21.0 and Expert Choice 2000, an AHP-only solution was used to do statistical processing through the processes of data coding and data cleaning. The findings showed that there was a partial difference of opinion between a group of field experts and a group of education experts. This indicates that the inconsistencies between educational training institutes and industrial sites should be resolved at this time of change with the aim of fostering field customized human resources with professional skills. Consequently, the solution is to combine jobs at industrial sites and standardized educations of educational institutes with human resources required at industrial sites.
