In this study, 27 pre-service teachers presented virtual mathematics instruction to develop his/her own teaching practice ability. I found several attributes in their virtual mathematics instruction such as connecting contents, asking justification, encouraging students' communication, representing variously, and using ICT etc. These will be the characteristics of the future mathematics class. When peer pre-service teachers assess presenter's instruction quantitatively, there are differences in the results between expert and pre-service teachers. Pre-service teachers didn't find the elements of student self assessment or group assessment and communication activities at the virtual instruction. When they assess peers' virtual instruction qualitatively, the results are specific or new ones compared with the quantitative assessment elements. Thus I suggested some implications for the mathematics pre-service teachers' virtual instruction in the view of teacher education.

The online education platform market is developing rapidly after the coronavirus infection-19 pandemic. As school classes at various levels are converted to non-face-to-face classes, interest in non-face-to-face online education is increasing more than ever. However, the majority of online platforms currently used are limited to the fragmentary functions of simply delivering images, voice and messages, and there are limitations to online hands-on training. Indeed, digital transformation is a traditional business method for increasing coding education and a corporate approach to service operation innovation strategy computing thinking power and platform model. There are many ways to evaluate a computer programmer's ability. Generally, piecemeal evaluation methods are used to evaluate results in time through coding tests. In this study, the purpose of this study is to propose a comprehensive evaluation of not only the results of writing, but also the execution process of the results, etc., and to evaluate the programmer's propensity habits based on the programmer's coding experience to evaluate the programmer's ability and productivity.

We live in a digital age. Smartphones are used by everyone from children to the elderly. And many smart devices are pouring out and changing our daily life a lot. However, even in the development of this digital age, there are some marginalized groups. There are also those who are reluctant to expose their information in the digital age. They have difficulty making reservations on their smartphones, using payment systems, logging into the site using various authentication and verification procedures, and entering and leaving buildings. We still carry most IDs, seals, certificates, etc. in physical form. Those who use smartphones are enjoying the convenience of the times. However, among the underprivileged, the desire to pass everything with only one device is growing. In this study, the most suitable smart band model was proposed by collecting the Delphi survey and the opinions of the general public. Future research is required to improve practical usability and utility by developing cheaper and more convenient models.

The smart factory promotion project is a project that uses ICT technology to improve the production process and the entire management environment system. In Korea, the smart factory promotion project has been continuously implemented since 2014, and the Smart Factory Promotion Team is supporting it nationally. The smart factory promotion project has shown positive results in some companies even in difficult environments such as the COVID-19 situation. In order for each company to promote the smart factory project, it must receive business approval through an evaluation based on the business plan. In order to receive business approval, it is important that the main contents described in the business plan (introduction (business) goals, qualitative goals, quantitative goals, functional composition diagram, etc.) are described consistently. In this study, we studied the cases of several companies to determine whether the main contents of the companies' business plans were consistent. The main contents to be maintained in consistency were the purpose and necessity of introduction, quantitative goals, qualitative goals, functional composition diagram, and expected effects.

This paper introduces analyzing the feature of drowning accidents in Korea and reviewing the method for reducing it. A lot of drowning accidents happen at inland areas such as lakes and rivers in Korea. Also, when the accident happens, systematic notify and rescue activity are carried out, but in terms of an accident prevention, there are many problems such as lack of management manpower and the difficulty of continuous monitoring about dangerous areas, etc. In order to resolve the problems about prevention of drowning accidents and the lack of the management, the role of the local governments is important, and using the ICT technology, it is effective to make use of monitoring remotely dangerous areas and developing control technology.

Electronics industry provides more revenue and jobs, and plays an important role in a variety of fields. During recent changes to the industrial strategy by IT convergence technology development and global economic integration, Global Value Chain(GVC) of the ICT industry has been expanded. The global value chain is a structure consisting of the global dimension in all the processes of business activity for value-added production, R&D, manufacturing, sales, A/S etc. The purpose of this study is to analyze the GVC in the electronics industry and GVC promote practice of Samsung Electronics and LG Electronics. GVC of the electronics industry was developed from 1980, and established manufacturing plant in the United States and Canada. GVC has moved to low-cost countries such as China, Taiwan and India to cut costs, In recent years, because of the rising labor and production costs in China, manufacturing plants move to the Vietnam that has relatively cheap production base. To develop consistently, Korean electronics companies should carry out a new strategy such as item and brand marketing to exporting country.

The walking exercise can alleviate stress and also it can improve health fortheir lifetime. Recent development in Information and Communication Technologies (ICT) has laid the foundation for Internet of Things (IoT) to become the future technology. IoT has many applications in industry automation, security, smart homes and cities, education, health etc. In personal health-care domain, IoT is mainly used for monitoring fitness condition by observing current activity of individual. In this paper, we have proposed a novel IoT based personal wellness care system. Proposed system not only keep track of current fitness level but also provide future activity prediction based on history data along with standard recommendations. Predicted activity helps in motivating the individual to achieve the desired fitness level. Initially, we consider only walking activity for testing purpose and later, other types of activities/exercise will be captured for improved health care support.

In BIM design, the construction and use of a library are very important. Since the existing contents can be re-used, the design can be executed more effectively and efficiently. Unlike the construction, the civil engineering, in particular, the railroad sees an inappropriate development and standardization of libraries. Thus, this study aims to develop and standardize the 3D object library in the railroad facility. We first gather and analyze the railroad facility breakdown structure and relevant drawings. We then match the items of analyzed standard drawings and the breakdown structure items. It was reviewed whether the library was required according to all items, and if required, it was reviewed what software was proper. Available software were found to be Civil 3D, Revit, etc. Based on this analysis, we will design the attribute items and specifications of the 3D railroad infrastructure library, as well as construct the library thereof.

Recently, nanotechnology has grown as one of the leading science technology along with other converging technologies such as biology, information, medicine etc., bringing the continuous investment of the government in nano-related field. However, it is difficult to measure and evaluate the performance of the national research and development programs because of the multidimensional character of the expected outcomes. This study aims to measuring efficiency of the national nanotechnology research and development programs using DEA model. The decision making units are nine nano-related ministries including the Ministry of Science, ICT and Future Planning. The input variables are total expenditure, number of the programs and average expenditure per program. The output variables are science, technology and economic indicator, and the combination of these outputs are respectively measured as seven different DEA cases. The Ministry of Science, ICT and Future was the first efficient ministry in total technical efficiency. Ministry of Agriculture, Food and Rural Affairs and the Ministry of Food and Drug Safety were efficient in pure technical efficiency, when the Ministry of Commerce Industry and Energy took the first in the scale efficiency. The program efficiency was affected by organizational characteristics such as the institution's scale, the concentration of the research paper or the patent, technology transfer or the commercialization. The result of this study could be utilized in development of the policy in the nanotechnology and the related field. Furthermore, it could be applied for the modification of expenditure management or the adjustment of the research and development programs' input and output scale for each ministry.
