댐의 용수공급능력이란 어떤 기간 동안에 저수지로부터 각종 용수로 공급할 수 있는 수량을 의미하고 통상 연간 공급가능량으로 표시되며, 평가기준인 이수안전도는 크게 보장공급량 기준과 신뢰도 기준으로 구분된다. 보장공급량이란 최악의 갈수기 동안에도 공급을 보장할 수 있는 최대공급량을 뜻하며 다년기준과 특정 한발년도 기준으로 구분된다. 신뢰도 기준은 장기간의 계획기간에 걸쳐 저수지운영을 통하여 전체기간 중에서 일정비율의 기간 동안만 물 부족을 허용하는 방법이고 연간단위기준, 기간단위기준 및 공급량단위기준으로 구분된다. 기존의 다목적댐의 경우 설계 시에 이수안전도를 다년기준 혹은 특정 한발년도 기준의 보장공급량 방식으로 용수공급능력을 평가하였으나 최근에는 적극적인 수자원의 활용을 위하여 신뢰도 기준의 이수안전도로 용수공급능력을 평가하고 있다. 본 연구에서는 설계 당시 이수안전도를 21개년간의 보장공급량으로 기준한 임하댐과 이수안전도를 '67~'68의 한발년으로 기준한 안동댐의 용수공급능력을 신뢰도 방식으로 재평가 하였고, 기본계획 공급량과 비교하여 추가용수공급 가능 여부를 검토하였다. 다년간 운영된 기존댐의 용수공급능력을 평가하기 위해서는 저수지를 하나의 시스템으로 고려하고 댐 운영시점에서의 유효저수량에 저수지 유입량, 강수량, 목적별 계획 용수 수요량, 홍수 시 월류, 방류량 등을 고려한 저수지 모의운영분석을 실시하여 물 부족량 및 용수공급능력을 계산한다. 본 연구에서는 안동댐과 임하댐의 30년 일 유입량 자료를 사용하여 단독운영 모의를 수행하였고, 30년 중 1회 물 부족발생(신뢰도 96.7%) 및 20년 중 1회 물 부족발생(신뢰도 95.0%)을 기준으로 연간단위 평가 및 월간단위 평가를 수행하여 각각의 용수공급능력을 산정하였다. 모의운영 결과 신뢰도 95.0%의 연간단위 평가 시 안동댐의 용수공급 가능량은 연간 893백만$m^3$, 임하댐의 용수공급 가능량은 연간 382백만$m^3$으로 안동댐과 임하댐 모두 기본계획공급량에 비하여 용수공급능력이 작게 산정되었다.

The purpose of this study was to suggest measures to improve safety and health training by analyzing trainees who participated in the training programs. A survey was administered to 226 trainees who participated in and completed the safety and health training programs provided by the Korea Occupational Safety and Health Agency. The study results showed that the level of satisfaction of employers for the training programs was the lowest compared to the middle managers and employees. Moreover, the middle managers' job competencies were increased, and they applied newly acquired knowledge and skills to their jobs. However, there were significant differences between industries. Finally, although all levels of trainee agreed on the effectiveness of safety and health training, the perceptions of employers were lower than those of employees. Based on these study results, several implications to improve the safety and health training were suggested.

This study examines the status of non-face-to-face online continuing education for radiological technologist working at medical institutions in a region, their satisfaction, and completion status, and provides basic data on the design and operation of continuing education predicted after the post-coronavirus. It was implemented to do. From January 5, 2021 to January 31, 2021, 255 radiological technologist license holders who completed online continuing education in 2020 were targeted. Satisfaction with online continuing education was higher as the age, male radiological technologist, and job title increased after obtaining a license. As for the status of completion of continuing education, the higher the age, the higher the percentage of regular members belonging to the branch, the more moderate the cost of continuing education of medical institutions was guaranteed, and the more the completion of the continuing education license and the recognition of legal restrictions. Based on the results of this study, in order to increase the satisfaction and completion of continuing education, it is necessary to develop various educational programs and contents according to age in preparation for the rapidly changing medical environment, and it is necessary to identify and provide members' needs.

Due to climatechange, precipitation variability has increased, leading to more frequentoccurrences of droughts and floods. To establish measures for managing waterresources in response to the increasing uncertainties of climate conditions, itis necessary to understand the variability of natural river discharge and theimpact of reservoir operation modeling considering dam inflow and artificialwater supply. In this study, an integrated rainfall-runoff and reservoiroperation modeling was applied to analyze the water supply reliability andflood risk for a multipurpose dam catchment under climate change conditions. Therainfall-runoff model employed was the modèle du Génie Rural à 4 paramètresJournalier (GR4J) model, and the reservoir operation model used was an R-basedmodel with the structure of HEC-Ressim. Applying the climate change scenariosuntil 2100 to the established integrated model, the changes in water supplyreliability and flood risk of the Happcheon Dam were quantitatively analyzed.The results of the water supply reliability analysis showed that under SSP2-4.5conditions, the water supply reliability was higher than that under SSP5-8.5conditions. Particularly, in the far-future period, the range of flood risk widened,and both SSP2-4.5 and SSP5-8.5 scenarios showed the highest median flood riskvalues. While precipitation and runoff were expected to increase by less than10%, dam-released flood discharge was projected to surge by over 120% comparedto the baseline

This study was carried out to evaluate on the job implementation of ITEC(Invention Teacher Education Center)'s in-service teacher training. To accomplish this purpose, teacher's perception on retention, usefulness, utilization, and enhancement were investigated after one year completing in-service teacher training. The populations of this study were 60 teachers completing in-service teacher training of the southeast ITEC. The methods of this study were survey research and qualitative content analysis. The subjects of survey research were 30 teachers and the case analysis objects were 12 epilogues of in-service teacher training. The mean of job implementation of southeast ITEC's in-service teacher training was 4.07 on a five-point scale. Teacher's perception on job implementation sub factors after one year completing in-service teacher training were as follows. The mean of enhancement factor was 4.39, usefulness factor was 4.11, utilization factor was 3.94, and retention factor was 3.82 on a five-point scale. The mean of enhancement factor and usefulness factor were relatively high level as compared with the mean of job implementation and the mean of utilization factor and retention factor were relatively low level as compared with the mean of job implementation. The results of qualitative content analysis about 12 epilogues of in-service teacher training, some significant instances were deducted that representable retention, usefulness, utilization, and enhancement factors directly and indirectly.
