Recently our government has presented the realization of 'Creative Economy' as a primary goal of the state administration through encouraging start-ups and ventures. Activation of entrepreneurship education is an important task for a national job creation and entrepreneurship activation policy. Since 2012, as a mid and long term project, the Korea Ministry of Education has led to activate creative entrepreneurship, entrepreneurship education and entrepreneurial culture within university by installing entrepreneurship centers respectively in 61 universities. In this study, we provide future entrepreneurship improvement subject and policy implication through the case analysis of entrepreneurship center operation and management. In order to achieve the research purpose, we will examine the program and condition of successful entrepreneurship centers in overseas universities and explore the factors that can enhance domestic entrepreneurship center development and operational effectiveness by analyzing 61 university-entrepreneurship center survey. First, primary research was conducted through survey focusing on organization and operation of centers, entrepreneurship education, startup support for students and entrepreneurship culture activation to proceed with comparative analysis. Through this case study, we expect to be able to derive policy implications for the effective operation of entrepreneurship center and the nurture of creative entrepreneurial young generation.

The construction industry has been experiencing a major challenge in its work force, 'the shortage of skilled craft workers.' This problem has been caused by several factors such as the poor image of the construction industry, lack of training and education, unclear career path, declining wages, and changing work force demographics. A 'step-change' approach called the 'Two-Tier Work Force Strategy' has been proposed by the Center for Construction Industry Studies (CCIS) to deal with the work force related issues in a radical way. It is composed of two separate strategies, Tier I and II. The Tier I strategy uses less skilled and task trained craft workers, and has a larger administrative site management team than the Tier II strategy. The Tier II strategy utilizes fewer, better-educated, and higher skilled workers who perform some lower-management functions in addition to craft functions. They are paid more, but produce more through higher skills, stay on the job longer through multi-skilling, and deliver improved project performance in safety, quality, schedule, and cost The Two-Tier Work Force Strategy has the potential to resolve the current work force problems and foster a better work force environment in the future.

During the development of the software, a variety of bugs are reported. Several bug tracking systems, such as, Bugzilla, MantisBT, Trac, JIRA, are used to deal with reported bug information in many open source development projects. Bug reports in bug tracking system would be triaged to manage bugs and determine developer who is responsible for resolving the bug report. As the size of the software is increasingly growing and bug reports tend to be duplicated, bug triage becomes more and more complex and difficult. In this paper, we present an approach to assign bug reports to appropriate developers, which is a main part of bug triage task. At first, words which have been included the resolved bug reports are classified according to each developer. Second, words in newly bug reports are selected. After first and second steps, vectors whose items are the selected words are generated. At the third step, TF-IDF(Term frequency - Inverse document frequency) of the each selected words are computed, which is the weight value of each vector item. Finally, the developers are recommended based on the similarity between the developer's word vector and the vector of new bug report. We conducted an experiment on Eclipse JDT and CDT project to show the applicability of the proposed approach. We also compared the proposed approach with an existing study which is based on machine learning. The experimental results show that the proposed approach is superior to existing method.

As a 360-degree image carries information of all directions, it often has too much information. Moreover, in order to investigate a 360-degree image on a 2D display, a user has to either click and drag the image with a mouse, or project it to a 2D panorama image, which inevitably introduces severe distortions. In consequence, investigating a 360-degree image and finding an object of interest in such a 360-degree image could be a tedious task. To resolve this issue, this paper proposes a method to find a region of interest and produces a 2D naturally looking image from a given 360-degree image that best matches a description given by a user in a natural language sentence. Our method also considers photo composition so that the resulting image is aesthetically pleasing. Our method first converts a 360-degree image to a 2D cubemap. As objects in a 360-degree image may appear distorted or split into multiple pieces in a typical cubemap, leading to failure of detection of such objects, we introduce a modified cubemap. Then our method applies a Long Short Term Memory (LSTM) network based object detection method to find a region of interest with a given natural language sentence. Finally, our method produces an image that contains the detected region, and also has aesthetically pleasing composition.

The risk of project failure has increased recently as ERP systems have been transformed into Web environments and task complexity has increased. Although low-code platform development tools are being used as a way to solve this problem, limitations exist as they are centered on UI. To overcome this, back-end development tools are required that can be developed quickly and easily, not only from the front development but also from a variety of development sources produced from the ERP development process, including back-end business services. In addition, the development tools included within existing ERP products require a lot of learning time from the perspective of beginner and intermediate developers due to high entry barriers. To address these shortcomings, this paper seeks to study ways to overcome the limitations of existing development tools within the ERP by providing customized development tool functions by enhancing the usability of ERP development tools suitable for each developer's skills and roles based on the requirements required by ERP development tools, such as reducing the time required for querying, automatic binding of data for testing for service-based units, and checking of source code quality.

Cultural heritage is the historic symbol implying the life of people and regionality. Accordingly, the study on cultural heritage along the border between Korea and China is a very critical and urgent task for educational purposes as well as to secure historic and cultural awareness and national identity. The border area between Korea and China is classified into the areas along Aprok River and areas along Tumen River where the cultural heritage of various ethnicities is scattered. Accordingly, this study tried to find the approaches to implement and use the exhibition contents for educational purposes as well as visual applications rather than a literary study on cultural heritage in the border area between Korea and China. The results of this study will be the opportunity to enhance the practical understanding of the modern states as well as to learn the cultural awareness of the territory of a modern state and people's awareness of the importance of world heritages. Furthermore, the results of this study will be used as the resources for historic and cultural tours on the web or applications and help to understand the cultural features of Korea and China in the northeastern region as well as historic awareness in educational programs using exhibition materials in a museum.

This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

With the recent increase in BIM orders in civil engineering, project owners are supplied with BIM-based products. Due to the lack of related guidelines, however, and the vague regulations on the creation and level of drawings as well as on the products list, many owners receive BIM-based products along with the existing 2D products. This can lead to task overlapping by designers or contractors and can cause the owners to have more data to maintain. If the existing 2D-based electronic supply system is changed to a BIM ordering system to reduce such a burden, it is necessary to examine the 2D products that can be extracted from or substituted for the BIM model so as to minimize the overlapping products. Therefore, in this study, BIM modeling of road construction projects whose enforcement plan by the Ministry of Land and Transportation has been completed was conducted, and based on the study results, the possibility of extracting 2D drawings from a total of 3,767 drawing items was determined. The results showed that 2,549 drawing items (67%) could be extracted as 2D drawings from the BIM model, and in particular, drawing items related to general connection work, earthwork, and amenities work could be most effectively substituted. The results of this study can be used as the base data for reducing the number of 2D drawings or substituting them in developing a BIM-based product supply system in the future.

The utilization of the achievements derived from the national R & D project is a key task of the science and technology industry policy that should lead the national economic growth by enhancing the investment efficiency of the national R&D. Although Korea has implemented various programs supporting technology transfer, commercialization, Performance is not sufficient. One of several causes may include inflexibility of a small or medium-sized company Priority System. This study is exploratory research on the directions for improving the current a small or medium-sized company Priority System. Results: First, Because the current SMEs Priority System contributes positively to enhancing SMEs R&D capability, We have to keep the system in principle. However, it is necessary to improve the direction of giving the strategic flexibility of the system so that the system is not operated formally. First, it is appropriate to make an exceptional contract with a person other than a small or medium-sized company, if a small and medium-sized company is not suitable for a technology execution contract due to the nature of technology. Second, it is desirable to consider the fulfillment of the obligations of this system when "sufficient efforts" are made to find a technical user.
