In this study, a smart bench was developed and researched smart benches that can contribute to user convenience and satisfaction by installing them in parks, bus stops, and tourist attractions in line with the rapidly changing construction of smart cities. The smart bench is automatically operated by the control system according to the external temperature and provides additional functions such as charging, lighting, and advertising to improve general bench functions as well as heating in winter and cooling in summer, making it suitable for smart urbanization. The developed smart bench is designed to be strong enough to withstand loads of about 2,500 N. It minimizes the visible parts such as assembled bolts and 220V power supply wires, It can also give aesthetic effects. The development was carried out with the aim of waterproofing and dustproofing of IP44 grade in accordance with the climate of Republic of Korea, which has four seasons, and it is advantageous for long-term use because the paint was selected for the weather ability (discoloration) grade 3 or higher. If smart bench is commercialized, it is believed that various options can be provided to the smart bench market, where buyers had few product options, as the parts were developed in an assembled type so that all functions can be responded in an optional form according to the installation environment and the buyer's budget.

In this study, in order to develop a method to efficiently inject essential nutrients necessary for plant growth into wood chips, which are simply used as soil covering materials in the agriculture, landscaping and horticultural industries, the atmospheric pressure dipping method and the vacuum pressure impregnating method are used to improve the plant nutrients injectability and impregnation amount were comparatively analyzed. Nutrient ingredients and 8 major heavy metal contents of wood chips injected with nutrients were analyzed, and soil covering effects were examined by covering wood chips injected with nutrients on soil. Comparing the dipping method and the vacuum pressure impregnation method, it took about 48 hours or more to inject 1,500 g or more of the nutrient aqueous solution into 1 kg of wood chips in the dipping method, but the vacuum pressure impregnation method could be impregnated in about 5 minutes. Components of the impregnated nutrients were detected in proportion to the diluted concentration. As a result of covering the wood chips developed in this study on soil, they showed weakly acidic pH, and the heat insulation and moisturizing effects during the winter season were evaluated to be superior to those of uncovered soil. In the future, wood chips impregnated with nutrients are expected to contribute to the more efficient use of waste wood resources and the long-term supply of nutrients essential for plant growth, reducing excessive use of chemical fertilizers and reducing costs.

This study proposes a new approach to real time implimemtation of shape recognition technology of die casting and forging parts based on robot vision for smart factory. The proposed shape recognition and inspection technology for forging and die casting parts is very useful for manufacturing process automatiom and smart factory including external form's automatic inspection of machanical or electronic panrs for the precision verification. The reliabiblity of proposed technology Ihas been illustrated through experiments.

This study aims to examine validity and reliability of the convergence talent measurement. Based on the comprehensive literature review on convergence and convergence talent, we draw 4 main competencies (convergence cognitive, accomplishment, problem solving, and attitude) and 10 critical aspects (creative thinking, critical thinking, cooperation, communication, problem-solving, knowledge accessibility, resource utilization, trust, openness, caring) for building an effective convergence-oriented organization. A validity and reliability test survey were conducted for the analysis to investigate the convergence talent scale. With a data of 151 employees in diverse companies, the results show that the factors demonstrated acceptable levels of validity and reliability. The empirical evidences of our study are 10 key aspects comprising four main dimensions which suggest an available scale for measuring the convergent talent for enhancing convergence-oriented organizations. Our research contributes to the expansion of academic and practical implications on convergence, especially in convergence-oriented organizations.

This paper empirically examines the portfolio diversification effect using data from both KOSPI and KOSDAQ. In KOSPI market, portfolio diversification effect disappears when more than 18 stocks are added in the portfolio. About 63% of portfolio risk is eliminated. In KOSDAQ market, the maximum portfolio diversification effect is achieved when 17 stocks are at least included in a portfolio. The maximum cumulative risk reduction is 35%.

The purpose of this paper is to examine the relationships among service quality, corporate image, and customer satisfaction of a financial institution in J city of Gyeongnam. The results show as follows. First, service quality affects positively corporate image. Second, service quality affects positively customer satisfaction. Third, corporate image affects positively customer satisfaction. Specifically, among the dimensions of service quality, the most significant predictor of corporate image is responsiveness, while the most significant predictor of customer satisfaction is tangibles. Further discussion and managerial implications can be drawn from these findings.

Standards offer numerous opportunities and benefits not only to provide effective and efficient way for business goals internally, but also to increase company's competitiveness externally. However SMBs can't get have benefits from standards management due to lack of resources and awareness. The purpose of this study is to investigate the role of standard management in business hierarchy from SMBs' cases leading to raising the awareness and providing strategic implications for standards management. The utilization of Standards management was investigated by adopting Anthony framework and Miles and Snow typology targeting SMBs which have awarded the World Standards Day Prize. The results of case study indicated that standards can be used as not only a strategic tool for achieving business goal and but also an effective way for raising brand awareness in global market. This study has originality and practical value in that it enhances the awareness and provides strategic implications for standards management in global business environment.
