  • 플랜트와 같은 대형 기계설비의 운영 시 발생하는 사고 피해를 최소화하고 조속한 정상화를 위해서는, 운영자 또는 초기 대응자가 예상치 못한 사고에 대처할 수 있는 능력을 향상시키기 위한 현장 운영자에 대한 훈련 기술이 필요하다. 이러한 훈련 과정은 실제 플랜트 현장에서 수행하기가 현실적으로 어렵기 때문에, 시뮬레이션 기술을 사용한 모의 훈련 및 평가기술이 필요하다. 본 연구에서는 이러한 가상현실 안전훈련 시뮬레이터의 설계 및 개발과정과, 체감형 훈련을 가능케하는 휴먼 인터페이스의 적용 및 통합 과정에 대해 소개한다.

  • 정보처리기술이 발달함에 따라 원자력시설에 대한 사이버침해 가능성이 갈수록 높아지고 있다. 방사능방재법 및 관련 법령에 의거하여 국내 원자력시설은 각 시설 별 사이버사건 비상대응 절차를 수립하고 절차의 유효성 및 비상대응조직의 대응역량을 제고하기 위한 목적의 주기적인 사이버사건 대응훈련을 실시하고 있으며, 규제기관의 독립적인 훈련평가 결과를 통해 많은 개선사항이 도출되고 있다. 본 논문에서는 현행 원자력시설의 사이버사건 대응훈련 체계를 분석하여 사이버사건대응 훈련 정책의 개념에 대해, 국내·외 기준에 따른 사이버사건 대응훈련 정책의 요소를 식별하여 이를 개선하기 위한 구체적인 규제방안을 제시한다.

  • This research aims to empirically explore the link between evaluation management and performance of indefinite-term contract workers in local governments, perceived by public officials who are responsible for managing indefinite-term contract workers in local governments. In addition, this study examines the moderating effect of training for the relationship between evaluation management and performance. The results show the positive relationship between evaluation management and performance with the moderating effect of training for the link. This research contributes to expand the scope and level of the literature on indefinite-term contract workers through suggesting the empirical evidence among evaluation management, performance and training. Furthermore, the empirical results of this study have useful implications for local governments and public officials to construct management guidelines for indefinite-term contract workers.

  • This paper reviews the implementation of the STCW 78/95 in the Philippine MET including the effects of the revised 2010 Manila Amendments. It discusses the country's maritime environment and the structures, quality of maritime education in the country and the effects on the maritime human resource. Among the various resolutions adopted at the conference, the standards of training and certifications, and promoting skills and competency will be more emphasized in this report. These will be compared with the existing curriculum mandated by CHED and upgrade STCW trainings advised by MTC for maritime institutions. A brief comparison and analysis with other Asian countries' maritime training shall be offered. The recommendation pinpoints to the weaknesses of the present maritime regimes in certification and evaluation of maritime institutions. It concludes with the need to have mutually acceptable evaluation standards in view of developing a competent human resource for the future.

  • The short term predictability of wind resources is an important factor in evaluating the economic feasibility of a wind power plant. As a method of improving the predictability, a Bayesian Kalman filter is applied as the model data postprocessing. At this time, a statistical training period is needed to evaluate the correlation between estimated model and observation data for several Kalman training periods. This study was quantitatively analyzes for the prediction characteristics according to different training periods. The prediction of the temperature and wind speed with 3-day short term Bayesian Kalman training at Taebaek area is more reasonable than that in applying the other training periods. In contrast, it may produce a good prediction result in Ieodo when applying the training period for more than six days. The prediction performance of a Bayesian Kalman filter is clearly improved in the case in which the Weather Research Forecast (WRF) model prediction performance is poor. On the other hand, the performance improvement of the WRF prediction is weak at the accurate point.

  • 팔당호는 북한강과 남한강이 합류하여 생성된 호소로 수도인 서울과 수도권인 경기도 동부지역의 물 공급을 담당하는 중요한 상수원이다. 이러한 팔당호에서 유해남조 발생은 상수원수 활용과 직접적으로 연관되어 있어 신속하고 정확한 관리 및 예측이 필요하다. 본 연구에서는 안전한 상수원 활용을 위해, 딥러닝 기법을 이용하여 유해남조 사전 예측 모델을 구축하고자 하였다. 모델 입력 변수는 2012년부터 2021년까지 10년 동안의 주간 팔당호 수질(수온, DO, BOD, COD, Chl-a, TN, TP, pH, 전기전도도, TDN, NH4N, NO3N, TDP, PO4P, 부유물질)과 수문(유입량, 총방류량), 기상 정보(평균기온, 최저기온, 최고기온, 일 강수량, 평균풍속, 평균 상대습도, 합계일조량), 그리고 북한강과 남한강 유입지점의 남조 세포 수를 사용하였다. 모델 출력 변수는 수질, 수문, 기상 요인으로 인한 남조의 성장 발현 시기를 고려하여 1주 후의 댐앞 남조 세포수를 사용하였다. 사용한 딥러닝 기법은 최근 주목받고 있는 Temporal Fusion Transformer (TFT)를 사용하였다. 모델 훈련용 데이터와 테스트용 데이터는 각각 8:2의 비율로 나누었으며, 검증용 데이터는 훈련용 데이터 내에서 훈련 데이터와 검증 데이터를 6:4 비율로 분배하였다. Lookback은 5로 설정하였고, 이는 주단위 데이터로 구성된 데이터세트의 특성을 반영한 것이다. 모델의 성능은 실측값과 예측값을 토대로 R-square와 Root Mean Squared Error (RMSE)를 계산하여 평가하였다. 모델학습은 총 154번 반복 진행되었으며, 이 중 성능이 가장 준수한 시점은 54번째 반복 시점으로 훈련손실 대비 검증손실이 가장 양호한 값을 나타냈다(훈련손실:0.443, 검증손실 0.380). R-square는 훈련단계에서 0.681, 검증단계에서 0.654였고, 테스트 단계에서 0.606으로 산출되었다. RMSE는 훈련단계에서 0.614(㎍/L), 검증단계에서 0.617(㎍/L), 테스트 단계에서 0.773(㎍/L)였다. 모델에 사용한 데이터세트가 주간 데이터라는 특성을 고려하면, 소규모 데이터를 사용하였음에도 본 연구에서 구축한 모델의 성능은 양호하다고 평가할 수 있다. 향후 연구에서 데이터세트를 보강하고 모델을 업데이트한다면, 모델의 성능을 더욱더 개선할 수 있을 것으로 기대된다.

  • In a study on effect of service education and training for tour conductors upon customer orientation and satisfaction it was shown that in view of insufficient service of education and training for tour conductors and increased number of population travelling by utilizing travel firms and their call for satisfying diverse demand there is need for customer oriented tour conductors to induce customer satisfaction through diverse role playing by tour conductors. It was indicated that such efforts lead to customer satisfaction and also has impact on improving image of company and on creating new customer. In view of such factors there is need for well planned, persistent education and training for service to heighten satisfaction of customer through well organized operation of service education and training program for tour conductors and through its continuous practice and experience.

  • In this paper we propose a VR-based Sailor Training Platform Authoring Tool which efficiently trains sailors in immersive ways. Proposed authoring tool consists of virtual environment reconstruction that imports real ship indoor environment into virtual environment and script editing which is able to implement various scenarios in emergency based on just drag-and-drop interface. The aim of importing real ship environment and supporting various VR devices is to enhance immersiveness and training so that trainees can deal with serious emergency events. Also the usefulness of the interface enables to reduce the cost of making training materials. Throughout scenario editing interface, the proposed authoring tool supports the editing of multi-user scenario and setting individual task for the evaluation.

  • Hearing - impaired children who have difficulty hearing and hearing go through pronunciation training. The purpose of this study is to provide the pronunciation training system based on digital contents that can be used for repeated hearing training while maintaining interest in hearing - impaired children. For this purpose, we conducted an interview survey for users and experts. Based on the results, we developed a digital content based pronunciation training system. Finally, to verify the effect of the digital service implemented, the user test was conducted for the hearing - impaired children. As a result of the interview, repeated training and interest factors were found to be essential factors affecting pronunciation training. In implementing digital services, we have used fairy tales and a variety of interactive elements to derive children's interests and designed a user flow that can train multiple words and sentences for effective repetition training. As a result of the test, this digital content was evaluated positively.
