  • This paper will describe the structure and characteristics of operator training system which was developed to maintain the quality of operational ability for COMS (Communication, Ocean and Meteorological Satellite) operators during a long-term nominal operations of missions and a contingency operations against an occurrence of anomaly. In particular it will present benefits and expected effects of the training system with a focus on three parts which are functions especially for trainer-friendly failure injection, an automatic sequencer of training scenario based on the predefined plan and additional functions of the existing COMS simulator. Furthermore, it will present a practical example of training on the training system to understand the overall mechanism of training process.

  • In order to establish the NIVTPD which is only one qualification training institute for vocational training teachers in Cameroon, the research team taught such as curriculum development methods, course materials development, and lecturing methodology for master teachers of NIVTPD. Also we prepared actual operation of NIVTPD by conducting actual lecture through Pilot training. This paper also includes two different surveys (Base-line and End-line surveys) results and two different tests (pre and post-test) results to assess the impact of training gained in NIVTPD on classroom performance. The results of the survey will be used for the improvement of NIVTPD's educational program through identifying the current state of the vocational training interface and integration, modification and improvement of the curriculum. Examination results can also be used as indicators for vocational training teachers' pedagogical knowledge and for future certification.

  • The purpose of this research is to analyze training needs for skill assessor's competency of vocational education teachers in Korea. This research was conducted based on Russ-Eft's competency model for skill assessor. Data were gathered from 234 vocational education teachers over the country, and final respondents were 158 males and 73 females. As a result of analysis, reliability for expert (needs score 2.51), establishment for assessment management plan (needs score 2.11), management plan (needs score 2.08), and effective collaboration (needs score 2.07) have high developmental needs. On the other hand, recognition of a variety intention (needs score 1.01), observation of ethical standard (needs score 1.24), and personal relationship (needs score 1.76) have low developmental needs.

  • 본 논문은 실시간 디지털 시뮬레이터(Real Time Digital Simulator, RTDS)를 이용한 송전계통의 자동 재폐로 모의 교육훈련시스템 개발에 대해 요약하였다. 본 논문에서 개발한 모의 훈련 코스는 3상 일괄 재폐로와 1상 및 3상 재폐로의 두 가지 부분으로 나뉘어 구성되었다. RTDS를 이용한 모의 파일의 구성 시 각 계통은 양단에 거리계전기를 설치한 것으로 모의하였으며 154kV 계통의 경우 송전단은 실제 거리계전기를 이용하여 구성하였다. 1상 및 3상 재폐로의 경우 1선지락 고장에 대해서는 해당상만 트림 및 재폐로를 하도록 하고 나머지 고장에 대해서는 3상 일괄트립 및 재폐로가 되도록 모의하였으며 대상 계통은 345kV의 전형적인 송전계통을 대상으로 하였다. 리셋 시간의 모의 훈련을 위해 현재 국내 리셋시간 기준치 이내에 또 다른 고장이 발생했을 경우와 기준시간 이상 경과한 후에 고장이 발생한 경우를 나누어 모의할 수 있도록 구성하였다. 고장종류, 고장지속시간, 1상 및 3상 재폐로 선택, 재폐로 횟수 및 재폐로 시간 등은 현재 한국전력의 재폐로 규정에 언급된 것을 모의하는 것은 물론 사용자 임의로 변경이 가능하도록 구성하였다. 본 논문에서 개발한 모의 훈련코스는 송전계통의 자동재폐로에 대한 실무자들의 이해 증진을 위한 교육용으로 사용될 수 있음은 물론 보호 계전기 등의 시험을 위해서도 활용될 수 있을 것으로 기대한다.

  • The priority job training program is one of key training programs in Korea. This training program has some fundamental problems. The process of selecting the detailed training jobs does not reveal the true training demand of industry sectors. The contracting-out process and control mechanism of the priority job training program show several weaknesses from the points of success conditions of contracting-out public services. In this paper, I proposed development strategies of the priority job training program. The contract period should be longer than one year so that the training institutions may invest for improving quality of training in the longer perspective and reduce transaction costs. The training fee pay mechanism should be more performance-based.

  • According to the dictionary definition Augmented Reality Technology is "an enhanced version of reality where live direct or indirect views of physical real-world environments are augmented with superimposed computer-generated images over a user's view of the real-world, thus enhancing one's current perception of reality". Since civilian property damages, noise and accidents during the field exercise by military or drills so that AR technology are indispensible with small units drills in Army. However because AR technology which Army has adopted are usually use for special units or need separate spaces which costs lots of budgets, those are not fit for small unit drills or tactics in regular Army. In this regards this paper suggests the AR technology which can apply small unit drill field and the efficiency and legal concerns thereof as well.

  • The need for education and training on engine-part maintenance is rising in order to prevent marine accidents occurring due to a surge in engine-part damages. However, practical training using actual equipment is difficult due to the size and location of the equipment. Therefore, the necessity of developing a training system for marine engines using virtual reality (VR) is intensifying. The purpose of this paper is to develop an optimized system for marine engine education and training using existing VR programs and equipment. To this end, we selected and modeled the marine engine and education target suitable for the class, and developed the system using VR development software. The developed VR education and training system is designed to experience content that is otherwise difficult to train or practice in the curriculum through virtual reality. In fact, fourth grade students from Maritime University were taught using marine engine VR educational equipment, and it confirmed that there was an educational effect on the class. In the future, the introduction of an education and training system using VR in the field of marine engines can improve their maintenance and repairing capacity, and aid in reducing marine accidents.need for education and training on engine part maintenance is increasing to prevent marine accidents.

  • Criticality prediction models to identify most fault-prone modules in the system early in the software development process help in allocation of resources and foster software quality improvement. Many models for identifying fault-prone modules using design complexity metrics have been suggested, but most of them are training models that need training data set. Most organizations cannot use these models because very few organizations have their own training data. This paper builds a prediction model based on a well-known supervised learning model, error backpropagation neural net, using design metrics quantifying SDL system specifications. To solve the problem of other models, this model is trained by generated virtual training data set. Some simulation studies have been performed to investigate feasibility of this model, and the results show that suggested model can be an alternative for the organizations without real training data to predict their software qualities.
