이러닝의 중요성과문화산업에의 파급효과 및 장래성에 대하여는 이미 많은 문건이나 발표로 알려져 있다. 이렇게 여러 분야에 중요한 효과를 가져가기 위해서는 교육의 양적 성장 뿐 만 아니라 효율적인 교육과 이에 대한 효과에 대해 관심을 기울여야 한다. 이미 미국이나 유럽을 중심으로 각종 이러닝 관련 연구를 통해 ROE(교육투자회임) 연구와 더불어 품질인증(QA : Quality Assurance)에 대한 중요성이 부각되고 있다. 이러한 움직임은 이러닝을 위한 교육자원의 상호운용 또는 활용이라는 측면에서 강조되어 온 이러닝 표준화와 연계되어 그 움직임이 활발히 진행되고 있다. 이러닝 품질표준화의 논의는 단순히 교육자원의 상호운용과 재사용이라는 측면에서 제시되어 온 메타데이터 관리 차원의 SCORM과 같은 기준 외에 교육자원의 생성으로부터 교육시스템 및 교육과정 운영에 이르기까지 그 영역이 광범위한 것에 주목할 필요가 있으며, 국가와 문화적으로도 다양한 환경을 고려해야만 할 것이다. 본고에서는 이러닝 품질보증 표준화의 정의와 범위 그리고 표준안을 만들기 위한 수행절차 및 적용방법 등을 살펴본 후에 외국의 개발 현황과 국내의 개발 현황을 비교함으로써 우리가 가져야 할 미래지향적 표준전략을 제시하고자 한다.

Purpose - In the 21st century, as information technology advances alongside the emergence of the 4th generation, industrial age, industrial environment has become individualized and customized. It is important to hire good quality employees for good service in the industry. The e-learning market is growing every year. Although e-learning companies are finding better quality employees in e-learning, it is not easy to find it. Companies also spend a lot of time and cost to find employee. On the employees side, they want to get a job freely when they want, but they cannot find their job easily. Furthermore, the labor market environment is changing fast. In the 4th generation, industrial age, employers require to find manpower whenever they need and want at little cost. So of their own accord, we have considered the necessity of management of human resources for employees and employers in e-learning. The purpose of this study is to propose a human cloud platform framework for enabling an efficient management of human resources in e-learning industry. Research design, data, and methodology - To pinpoint the items of a human cloud platform framework, the study was initiated according to the following process. First, items of competency relating to e-learning instructional designer was analyzed. Second, based on the items of information from this analysis, selection and validity verification took place with 5 e-learning specialists group. Third, the opinion of experts who were in charge of hiring in e-learning companies were collated with the questionnaire. Lastly, the human cloud platform framework was proposed based on opinion results. Results - The framework was comprised of 7 domains and 27 items in order to develop the human cloud platform for e-learning instructional designer. The analysis results showed that the most highly considered item were 'skill (4.60)' that employee already have the capability. Following this (in order) were 'project type (4.56)', 'work competency (4.56)', and 'strength area of instructional design (4.52)'. Conclusions - The 27 items in the human cloud platform framework were suggested in this study. Following this, we can consider to develop the human cloud platform for finding a job and hiring e-learning instructional designer easily. For successful platform operation, we need to consider reliability between employer and employee. In addition, we need quality assurance system based on operation has public confidence.

The purpose of this study is to investigate Chinese e-Learning development strategies based on the analysis of Korean Industry-Academia e-Learning cooperation. Literature review and interview with experts about the subject regarding this study were the main research methods for the study. The results of the study are as follows 1. Chinese government should amend and complement the e-Learning policy of the chinese enterprise continuously through the Korean government's experience about the e-Learning policy such as enterprise e-Learning system, standardization of LMS, and quality assurance. 2. Korean government's policy about e-Learning has emphasized on practical development of e-Learning contents and LMS. And we have found they have good effects from the policy in terms of human resource development. However, Chinese government generally has emphasized on external extension of the scale and administration.nte, Chinese government should follow the practical policy in the e-Learning development as Korean government has done. 3. The way of Individualized learning, cooperative learning, team work, WBI, standardized LMS, and Blended Learning in Korea could be well adapted in Chinese e-Learning.

These days, the teaching and learning system has been increasing for the rapid advancement of the information technologies. We can access education systems of good quality anytime, anywhere and we can use the individually personalized teaching and learning system depending on developing the wireless communication technology and the multimedia processing technology. The more the various systems develop, the more software security systems become important. There are a lot kind of fault analysis methods to evaluate software security systems. However, the only assessment method to evaluate software security system is not enough to analysis properly on account of the various types and characteristic of software systems by progressing information technology. Therefore, this paper proposes an integrative method of Fault Tree Analysis (FTA) and Fault Modes and Effect Analysis(FMEA) to evaluate the security of e-teaching and learning system as an illustration.

The purpose of this study is to develop and use the e-learning contents accessibility guidelines to improve contents accessibility for the non-technical developers and designers. The accessibility guidelines used for web or digital contents are usually technical, field dependent, or specific that are not friendly for many developers or designers. In this study, the e-Learning Contents Accessibility Guidelines was developed based on the principles of Universal Design for Learning. The guidelines could be used to map the necessary skills for the developers and the instructional designers. In this study, 5 users with different disabilities tested 6 e-learning contents, and surveyed e-learning experts to identify core elements for accessibility guidelines. Due to the limited accessibility of the contents, we need to offer manuals and training for developers and designers, need collaborative efforts between different stake holders, include accessibility in quality assurance guidelines, and further research to improve accessibility for many existing Flash contents.

The Korea Ministry of Education, Science and Technology (MEST) determines admission quota of cyber universities. MEST's decision is made based on each university's physical and administrative capacity for handling admission numbers. However, the unique characteristics of cyber universities (e.g., online teaching and learning environments) are not considered in MEST's current decision process. MEST also lacks specifics in their policies that are required to ensure university's autonomous control for admission number as well as learners' rights and quality assurance. This study intended to improve decision making process on admission quota of cyber universities so as to increase quality assurance of education. The alternative admission quota decision frameworks have been formulated based on (a) the analysis of the current practices of cyber universities, (b) focus group interviews, and (c) recommendations of the expert.

Accurate prediction of concrete compressive strength can minimize the need for extensive, time-consuming, and costly mixture optimization testing and analysis. This study attempts to enhance the prediction accuracy of compressive strength using stacking ensemble machine learning (ML) with feature engineering techniques. Seven alternative ML models of increasing complexity were implemented and compared, including linear regression, SVM, decision tree, multiple layer perceptron, random forest, Xgboost and Adaboost. To further improve the prediction accuracy, a ML pipeline was proposed in which the feature engineering technique was implemented, and a two-layer stacked model was developed. The k-fold cross-validation approach was employed to optimize model parameters and train the stacked model. The stacked model showed superior performance in predicting concrete compressive strength with a correlation of determination (R²) of 0.985. Feature (i.e., variable) importance was determined to demonstrate how useful the synthetic features are in prediction and provide better interpretability of the data and the model. The methodology in this study promotes a more thorough assessment of alternative ML algorithms and rather than focusing on any single ML model type for concrete compressive strength prediction.
