This study tried to explore factors for improving academic achievement in online non-face-to-face education based on the survey results of a University's online cooperative learning Q&A. Due to the Corona situation, both professors and learners can easily feel psychological isolation due to the implementation of all non-face-to-face online classes. As one of the methods, it was intended to suggest the direction of future education to various teachers and learners by sharing class cases in which the online cooperative learning methodology was applied. Previous studies on non-face-to-face online learning, online cooperative learning, and learning promotion method were reviewed, and the online Q&A method was adopted as a specific learning promotion method to conduct research. In the Q&A process, learners were given an opportunity to check their learning content, share knowledge and communicate, and performance evaluation-related factors such as guaranteeing anonymity of the questioner and answerer, improvement points system, and absolute evaluation were asked. As a result of the survey analysis, it was found that they are the success factors of online cooperative learning. It is a small change that can be applied in practice in the future where online non-face-to-face learning is likely to continue, but by sharing meaningful cases of application of teaching methodologies, both professors and learners being motivated and actively involved in. It is expected that we will be able to suggest methods and directions for improving skills together by changing and supplementing the learning field.

Information Technology(IT) was introduced to the business as a means of improving operational efficiency. Nowadays, IT has become an essential component of an organization's survival. Almost no operations of an organization can be performed without IT. The benefits of using IT in organizations can not be underestimated. Some organizations have flourished because of the competitive advantages derived from the IT systems they have developed. Most IT systems, however, have been extended, changed and integrated with ad-hoc and makeshift solutions without thinking long-range view. It results in high maintenance cost and uncontrolled system for managing information resources. Especially, public institutions under the Project-Based System (PBS) have some problems in keeping a good management systems for information resource, because they are usually operated for a set period. Therefore, we propose the framework how to efficiently manage the IT assets and resources based on the Information Technology Architecture (ITA) that is introduced for the overall optimization of IT investment, change management and inter-operability.

Asphalt, widely used for road pavement, has different required physical properties depending on the environment to which the road is exposed. Therefore, it is essential to maximize the life of asphalt roads by evaluating the physical properties of asphalt according to additives and selecting an appropriate formulation considering road traffic and climatic environment. Dynamic shear rheometer(DSR) test is mainly used to measure resistance to rutting among various physical properties of asphalt. However, the DSR test has limitations in that the results are different depending on the experimental setting and can only be measured within a specific temperature range. Therefore, in this study, to overcome the limitations of the DSR test, the rheological characteristics were predicted by learning the images collected from atomic force microscopy. Images and rheology properties were trained through EfficientNet, one of the deep learning architectures, and transfer learning was used to overcome the limitation of the deep learning model, which require many data. The trained model predicted the rheological properties of the asphalt binder with high accuracy even though different types of additives were used. In particular, it was possible to train faster than when transfer learning was not used.

Recently, students have raised negative awareness of the test because of school records and irrational difficulty level of the College Scholastic Ability Test. They go so far as to commit suicide because of failure in entering school. It becomes a social problem and it is rising more and more interested in entering school. The educational game was created based on considering this social environment. Namely, students can enter university as playing online or mobile game through Enter Literacy Assessment game service. The Enter Literacy Assessment game service provides various tests which are math, english, science or essay that real university wants through online or mobile game. For this, general concept about Enter Literacy Assessment game service and characteristic establishment and limitation of existing research should be understood. The research refers to relationship between Self-Determination Theory which is the representative theory related with psychological desire of human intrinsic and Enter Literacy Assessment game service. Therefore, development of Enter Literacy assessment Serious Game is a new opportunity factor to take two dominants which are secure of university competitive power and excellent personnel and challenge for development of serious game.

This study was designed to insist on the need of introducing the position of dramaturgs as professionals at performance venues. A dramaturg is a professional staff member that proposes an artistic orientation in the making process of performing arts works such as play and dance. Dramaturgs are divided into production dramaturgs participating in individual works and permanent dramaturgs resident in the theater. In the present study, discussions developed around plans to make use of permanent dramaturgs at local public theaters. The study introduced the advantages of the dramaturg position at culture and arts centers serving as a public theater in the community and proposed institutional improvement measures for it. At a culture and arts center, a dramaturg will play the roles of expanding culture and arts service to local residents, increasing creative chances for local artists, contribution to the vitalization of local culture, and narrowing the cultural gap between the Seoul metropolitan region and the rest of the nation. The introduction of a permanent dramaturg system should be supported by efforts across various aspects including the revision of Culture and Arts Promotion Act and Public Performance Act, improvement of the management system of culture and arts centers, change of performance evaluation methods for performance venues, and introduction of a cultivation course for the public sector.

Determining the price of a newly developed game product is a substantial matter affecting many aspects of corporate management. An appropriate pricing based on the proper data encourages consumers to purchase products repeatedly Yet presently most game companies prefer to set a price according to the cost including developing expense, advertising expense and law materials. As a result that price does not reveal the rue value of the product, many corporations face the demerits in the corporate management including the low sales, the loss of client and the poor promotion. This study has emphasis on the evaluating the price according to the consumer view rather than either corporate or industrial view. The price preference research analysis shows that Korean gamers prefer the price ranging around 30 thousand won in the simulation game, RPG game, and arcade game. In the online game, around 20 thousand won is the preferred price. This difference explains well the features of each game categories.

The underground buried pipelines of Natural gas are relatively safer than any other pipelines of chemical plants, because Natural gas is non-corrosive fluid. But Natural gas is supplied normally the downtown area. So, it may be a disaster because of corrosion which is caused interference facilities, environment and third party accident which is caused facilities construction. Especially, it is very difficult to find out and inspect damages of pipeline because of buried pipelines. Therefore this paper approached to select and manage risk region pipelines according to introduction of underground buried pipeline's risk concept. Risk was indicated three parts - corrosion factor, design and construction factor, maintence and management factor - in this paper, Therefore qualitive risk of pipelines showed score as quantitative number. Also it was thought to be helpful in confidence and safety management that the concept of key index and failure supplementation measures to cost introduces this program. We developed this risk assessment program using visual basic tool and interfaced GIS.

This paper shows the case of the evolution of Korean e-Government services in the theoretical lens of Actor-Network Theory and Structuration Theory. It presents how human actors (i.e. presidents and the central administrations) and non-human actors (i.e. law, standards, and relay systems) have established as the one network together, and how this network affects the evolution of Korean e-Government services. This case demonstrates in public sector can adopt not only Actor-Network Theory, but also Structuration Theory to explain both micro and macro contexts. The practical implications are given especially for the developing countries in pursuing the rapid development process of e-Government services.
