In response to the significant COVID-19 outbreak, countries have enforced the use of E-learning systems as an alternative to traditional learning; to contain the virus and minimize the infection rate while maintaining the continuity of the learning experience. However, the effective adoption of E-learning systems requires a well-understanding of critical factors, especially in times of crisis. In this regard, this study intends to assess the success of the E-learning system adoption by Higher Education Institutions (HEIs) during the crisis of COVID-19 by utilizing the Information Systems Success (ISS) model. This study's adopted model consists of nine interdependent dimensions, namely: Technical System Quality, Information Quality, Service Quality, Learner Quality, Perceived Satisfaction, Perceived Usefulness, System Use, Intention to Use, and System Success. An electronic survey was distributed among higher education students from different universities in Saudi Arabia to explore each model's dimension. Structural Equation Modeling (SEM) has been applied via SmartPLS software to test the causal relationships between dimensions. This study's main results revealed that students' Service Quality, Learner Quality, and the Intention to Use by students are essential drives for E-learning System Use during the Covid-19 pandemic. Meanwhile, the Intention to Use the system is significantly influenced by Perceived Satisfaction and Perceived Usefulness dimensions. Further, Perceived Satisfaction, Perceived Usefulness, and System Use are interdependent, and all three have a significant positive impact on E-learning System Success.

In the 1990s, university environment is changing rapidly(especially, difficulty of student registration which are originated student's decrease and various deregulation) and university get ready for the new ways of management culture. This new ways are management innovation strategies. The purpose of this study is to suggest the direction of effective innovation(to search application possibility of management innovation strategy), solving the problems occurred by the enlargement and change in the environments of universities. From early in the 1990s, korean corporations perform actively many management innovation strategy including benchmarking, restructuring, downsizing, zero-based budgeting, BPR, learn organization and total quality management. But korean most universities performed hardware management innovation strategies such as corporate portfolio restructuring(including outsourcing, M&A, MBO etc.) and organization restructuring. Therefore korean universities have got to concerns about more software management innovation strategy such as total quality management and learn organization. Also we have seen another problems such as that universities try to merely duplicate certain management innovation strategies which are used by another university. rather than to make various effort to adequate their own organizations. In conclusion, korean universities are to play an important roles in the development of knowledge society. The management innovation and individual competence development in the university are required to overcome crisis of university.

In respond to the global energy crisis and climate change, there have been many ongoing national efforts to develop a sustainable housing prototype followed by "2 million Green Home Project" in Korea. More than 50% of nation's population are currently living in apartment housing thus the country is seriously in need of developing green apartment prototype. In this research, we focused on energy-conservative green apartment design prototype that have both passive components and active systems explored in a systemic design approach. After selecting an existing basic apartment unit, we analyzed and compared statistical data with the simulated annual energy consumption to match these two data sets for validating simulation accuracy performed with TRNSYS package. We performed energy simulations with different passive design factors such as varied insulation thickness, window types and infiltration rates as well as the active design factors including boilers and lighting fixtures to analyze their impacts on the energy performance of the housing unit using TRNSYS software. As a result, we acquired significant energy reduction effect with explored design strategies but the life cycle cost analysis for the final design guidline would need to be performed. In this study, we focused on a systematic comparative energy analysis based on TRNSYS that can improve the design of a green apartment housing.
