기존에 개발된 스마트 가로등 관리 시스템은 도로에 설치된 가로등을 관리 및 유지보수하기 위해서 많은 시간과 비용이 필요하여 현재까지도 보급률이 매우 낮다. 따라서 본 논문에서는 기존의 가로등 관리 시스템들과 달리 장거리 통신이 가능하며 초기비용 및 유지비용이 상대적으로 저렴한 Long Range Wide-Area Network (LoRaWAN)통신을 이용한 가로등 관리 시스템을 제안한다. 또한 가로등의 상태 및 가로등 주변의 환경을 GUI에서 실시간 모니터링 및 제어를 하여 설치된 가로등에 문제가 발생 시 빠른 시간 내에 이를 확인할 수 있다. 마지막으로 구현된 시스템의 LoRaWAN 통신 테스트 및 센서 정확도 테스트를 실시하여 시스템의 성능을 검증한다. Supply rate is very low because conventional smart system of streetlight management requires a lot of time and cost until now. In this paper, we demonstrated maintaining system for streetlight which uses LoRaWAN to solve following those reasons. Using LoRaWAN is subject to build long range and low power communication. Furthermore, it helps to make low initial and cost for maintenance. Detecting problem of streetlight in real time and controling streetlight based on situation and environment are additional benefits. This system on control part is carried by administrator in GUI environment. Finally, we verified the proposed system of performance for LoRaWAN communication and sensor accuracy.
The purpose of this study is to investigate the effects of children``s temperament and mothers`` reactions to negative emotions on the children``s emotional regulation. The participants were 413 mothers of 4 to 6-year-old children. Cronbach``s α, correlation analysis and hierarchical regression analyses were conducted using SPSS 22.0. The results of this study were as follows: First, the mothers’ reactions to negative emotions had a separate influence on children``s emotional regulation besides children``s temperament. Second, problem-focused responses and punitive responses had a common effect on children``s emotional regulation. This study verified the effects of children``s temperament and mothers`` reactions to negative emotions on the children``s emotional regulation, and it found out that mothers`` reactions to negative emotions had an independent influence on children``s emotional regulation.
기업이 실시하고 있는 다양한 마케팅 방법 중의 효과적으로 알려진 로열티 프로그램에 대 한 정의와 실시된 배경과 그 과정 그리고 현재까지의 발전된 모습을 통해 소비자에게는 실 용적이고 쾌락적인 혜택을 준다는 것이 확인되었으며, 기업에게는 포화된 시장에서의 고객 과의 관계를 유지시키며 이 관계에서 더 나아가 새로운 고객을 확보하는데 영향을 주고 있 음을 알았다. 그러나 모방이 되기 쉽고 단기적인 영향을 끼치며 높아지는 소비자의 기대를 충족시키기에 문제가 있다는 점에서 장기적인 관점과 더불어 세분화된 시장에 전략적으로 접근하는 노력이 필요하며, 각 분야의 협력을 통해 구체적인 방안을 마련해야함을 조언한다.
문화와 관광이 각광받고 있는 지금, 그 소비의 주체인 관광소비자의 행동과 이들의 행동을 이끌 국가와 기업에서 실시하고 있는 다양한 마케팅 방법 중 문화관광 마케팅이 관광소비자의 행동에 미치는 영향을 사례를 통해 분석하였다. 이를 통해 각 관광소비자의 행동을 분석하는 것과 통합적인 데이터베이스를 구축하여 보다 거시적인 시각에서 고객행동을 분석하여 세분화된 시장으로 접근해야 함을 조언한다.
A new approach to growth engine policy is needed as the internal and external environment has changed rapidly, our economy and industry have grown more than in the past, and the achievements of the existing growth engine policy have been insufficient. The purpose of this study is to evaluate the Growth Engine Policies and to suggest implications for future growth engine policies based on the evaluation results. In chapter 2, we review the previous studies on the evaluation of growth engine policies that have been conducted and propose a framework for analysis based on the theoretical background. After reviewing the researches of various research institutes, we review the contents of major government policy evaluation programs that are closely related to the analytical framework of our research. And we present our analytical framework for evaluation of growth engine policies and programs. In chapter 3, we analyze the trend of overseas growth engine policies. This course examines the current status and implications of growth engine policies in the US, Japan, Europe and China. In particular, the background and progress of the growth engine policy, the main promotion areas and technology development trends, in particular, the main contents of technology development, strategies and systems, policy effects and problems, and implications for Korea. In chapter 4, we analyze and evaluate the growth engine policies. The analysis targets are five growth engine projects including the G7 project, next generation growth engine program, new growth engine program, future growth engine program and innovation growth engine program. The focus of evaluation analysis is on policy evaluation, which looks at the formation of policies driven by the necessity of policies, policy enforcement related to the implementation of established policies, and the policy effects of policy enforcement. At the policy formation stage, we check whether the policy agenda and policy alternatives have been properly established, and whether the policy has a clear basis for implementation. Whether the policy has been carried out, the implementation of a policy that effectively enforces the policy, and whether the policy has been achieved, the policy evaluation will examine whether the policy has been achieved and what the effect of the policy will be and what will be the success or failure of the policy. Finally, in the last chapter, we summarize the discussions so far and present the policy implications for which direction the growth engine policy should be improved in order for the growth engine policy to succeed.
Despite the government"s announcement of the hydrogen economy revitalization roadmap, there are various policy challenges and various technical challenges that must be addressed for the smooth transition to the hydrogen economy. Therefore, we first look at the achievements and limitations of the hydrogen technology roadmap policy announced in 2005 and compare it with the recent hydrogen economy roadmap. This is a good example of what we need to keep in mind as we move forward to the hydrogen economy. In order to forecast the future of the hydrogen economy from the perspective of future research, the factors that make the future pessimistic and the optimistic prospect are examined. Based on this, the future of the hydrogen economy will be forecasted and the policy tasks for implementing the hydrogen economy will be examined. Chapter 2 reviews the concepts and characteristics of hydrogen, the contents of technologies related to hydrogen production, storage, transportation and utilization, and the concepts and characteristics of hydrogen economy in order to enhance understanding of hydrogen and hydrogen economy. Chapter 3 examines the domestic hydrogen economic policy, the trend of hydrogen economy, and the trend of technology development. First, we will examine the policy contents for hydrogen technology development, hydrogen industry development policy, and hydrogen industry ecosystem. The performance and limitations of the 2005 hydrogen economy roadmap and the feasibility and challenges of the 2019 hydrogen economy roadmap will be discussed. And We deal with the current status and prospect of hydrogen economy and industry, Finally examine its status and characteristics. of national R & D projects related to hydrogen technology from NTIS DB. Chapter 4 examines the trends and prospects of hydrogen economic policies, hydrogen economy, and hydrogen technology development in Japan, the US, China, and the EU. Chapter 5 presents policy tasks along with future prospects for the hydrogen economy. First, we will examine the major issues related to the transition to the hydrogen economy, and then we will summarize the factors that make the future of the hydrogen economy pessimistic and optimistic. And in the last section, we will look into what policy tasks are needed for a smooth hydrogen economy.
