Recent demands for mobile robots showed that those focus on the areas requiring mobility, such as delivery and logistics. At the same time, the development of mobile robots is also actively ongoing. In the case of mobile small-scaled robots, wireless communication is essential for most applications to connect and interact with external entities in various situations. However, existing communication protocols currently applied to small mobile robots were developed with different objectives. In other words, those wireless protocols may serve poorly for mobile robots. It is necessary to consider the future or optimal wireless communication for mobile robots via an in-depth analysis of communication protocols already applied to small mobile robots. In this paper, we aim to implement the comprehensive analysis and investigation of mobile robot trends and related service cases to provide directions and considerations for future robot-dedicated wireless communication protocols. In addition, we developed the service scenarios and generalized system structure of mobile robots with wireless protocols. We listed considerations and technical and policy directions as well.

The market for electric vehicles is growing due to the public's interest in the environment and the expansion of electric vehicle support projects in terms of government policy. This study surveyed 2,332 people in Jeju, one of the nation's representative areas of electric vehicles, and the higher the perceived value in terms of the total cost of automobile ownership for electric vehicles, the higher the intention to purchase electric vehicles. The higher the level of knowledge and attachment, the higher the intention to purchase electric vehicles. While many previous studies considered economic value mainly as price, the study was conducted to approach economic value in terms of total cost of ownership. Marketing practitioners also look for practical contributions in that they can propose price framing so that customers can judge the economic value of the electric vehicle as a strategic way to increase the intention to purchase the electric vehicle, rather than just the purchase price. can see. In addition, the same research should be conducted in various regions besides Jeju, so that the research results can be generalized.

This study present a comparison of prevailing practices of livestock farm carcasses disposal procedures in Korea with the management guideline and regulations of other countries. It has found that there is a significant difference among the guidelines for livestock mortality management based on the livestock feeding and waste disposal. Based on the finding it may require a concrete guidelines and regulation for disposing livestock carcasses considering nutrient balance both in soil and water environment. Conclusively, a centralized treatment plant equipped with highly sophisticated system (specialized knowledge and technology) is required for the final carcass disposal.
초등학생의 관현악 합주 활동이 인지능력 발달에 미치는 영향

본 연구는 풍부한 음악적 경험을 제공하는 초등학생의 관현악 합주 활동이 인지능력 발달에 미치는 영향을 알아보는데 목적을 두었다. 부산 해운대구에 소재한 'B 초등학교'의 교내 관현악단 단원으로 합주 활동에 참여하고 있는 학생 60명과 그들의 담임교사 20명을 대상으로 설문조사를 실시하였다. 설문 조사는 선행연구를 참고하여 인지능력을 학업성취, 학습동기, 학습태도, 학습습관, 학습기술 5가지 하위영역으로 세분화한 뒤, 각 영역별로 설문 문항을 만들어 관현악합주 활동을 하기 전과 후를 비교하였다. 또, 관현악단 단원을 맡고 있는 담임교사와의 심층 인터뷰를 통하여 설문조사의 의미를 명료히 하고 그 원인을 찾아내어, 초등학교 교육 현장에서의 합주 활동의 중요성을 재확인시키고자 하였다.

This study was conducted to development of a regional livestock manure treatment model based on nutrient balance. The treatment model converted from compostingoriented livestock manure treatment to wastewater treatment and solid refuse fuel in public treatment facilities due to the excess nutrient balance of arable land. The inputs of 15.2% nitrogen and 22.6% phosphorus decreased, and all could be accommodated through nutrients consumed by crop cultivation. Therefore, applying regional livestock manure treatment models and nutrient management plans that control chemical fertilizers and organic fertilizers, which are the sources of nutrient input, is expected to activate a crop-livestock farming system that considers crop productivity and soil environment.

This study conducted a status survey on livestock carcasses' occurrence and disposal by livestock species in Korea for livestock farms, slaughterhouses, and private disposal facilities. The annual amount of livestock carcass in Korea is 158,000 tons, and the mortality rate by livestock species is 2.4% for beef cattle, 4.8% for dairy cattle, 19.9% for swine, 6.7% for broilers, 4.9% for layers, and 3.8% for ducks. Most of the livestock carcasses generated are buried or composted on the farm. As the number of dead livestock is expected to increase steadily, a management system for the occurrence of livestock carcasses and storage-disposal-recycle is urgent to establish.
