The study introduced an actual American university program student's learning outcomes in instructional technology integration knowledge in order to acknowledge implication considering the current status of relevant Korean teacher training programs. With utilizing complete sampling (students enrolled in a master's program in Instructional Systems Technology at the N University in Fall 2015), the survey was conducted on knowledge, strategies and performance in instructional technology integration, and interview assessed deeper understanding of students' relevant competencies in their specific professional setting. The results and findings based on triangulation of the data confirmed that the students gained sufficient knowledge, and applied the relevant knowledge and competencies into their work setting. For future research, the implications were offered on reviewing Korean teacher training programs in professional competency development related to technology integration in teaching and learning.

In this research, we designed an educational activities of exploring mathematics programs in a course of mathematics education in teacher's college. We divided future mathematics teachers into 8 groups and suggested 8 mathematics programs to them. Each group explored one mathematics program. We asked to future mathematics teachers exploring some cases that use effectively a mathematics program in the teaching of school mathematics. In the process of an exploring, we designed some activities of teaching and learning. We provided opportunities of long-term exploration, group learning, presentations, exercises, reflections to mathematics teachers. As a result, future mathematics teachers acquired basic knowledge on the usage of mathematics programs in school mathematics textbook. In addition, their capabilities that are needed to explore mathematics programs have been enhanced. Also they had learned the teacher's positive attitude through the activities of teaching and learning.

98.8% of accidents occurring in domestic companies are concentrated in small-sized workplaces with fewer than 50 employees. Therefore, this study developed a disaster safety program that can be implemented by small and medium-sized enterprises by comparing and analyzing the safety management system actively used with the laws and regulations related to industrial safety and facilities. The disaster and safety program included the scope of application, organizational structure, risk assessment, emergency response system, education and training, safety equipment provision and program evaluation, and detailed preparation methods and procedures for each item. In addition, items to be aware of when operating a disaster safety program and operational strategies were presented. After that, it was proposed to introduce the research results into the Occupational Safety and Health Act.

ERC-20, the standard API for Ethereum token smart contracts, was introduced to ensure compatibility among applications such as wallets and decentralized exchanges. However, many compatibility vulnerability problems have existed because there is no rigorous functional specifications for each API nor conformance review tools for the standard. In this paper, we proposed a new review procedure and a tool to perform the procedure to review if ERC-20 token smart contract programs for the Ethereum blockchain conform to the de facto standards. Based on the knowledge from an analysis on the ERC-20 API functional behavior of the top 100 token smart contract programs in the existing Ethereum blockchain, a new specification for the de facto standard for ERC-20 API was explicitly defined. The new specification enabled us to design a systematic review method for Ethereum smart contract programs. We developed a tool to support this review method and we evaluated a few benchmark programs with the tool.
