In general the tickets are essential to buy goods and take services, which are used in various fields of modern society, and there have been several types of tickets such as a paper and an RFID chip. However, the conventional system has a problem like a loss of ticket or forge. thus there have many efforts to compensate the problem. In this paper, by improving the conventional system through the connection between a smart-phone with a server system, a smart ticketing system without paper tickets is proposed. The proposed system can support efficient services for managers and users in terms of timesaving and reliability. The proposed system can be applied in various similar fields requiring a ticket system.

일본 인쇄산업은 지난 2011년 동일본 대지진 이전과 이후로 그 인식과 대처가 크게 달라졌다. 인쇄산업에 있어서 커다란 과제와 역할을 부여하는 기회가 됐다고 할 수 있다. 실제로 당시 동일본 지역 일대에서는 대지진과 쓰나미로 인해 제지공장과 잉크 등 관련 자재공장에 연이어 재해가 발생했으며, 용지, 필름, 잉크 등의 생산이 불가능해지고, 공급도 부족함에 따라 가격이 폭등하는 위기상황이 초래하기도 했다.

Recently, numerous studies are being performed to examine alkali-activated cement which uses industrial by-products, such as GGBS and fly ash, as well as alkali activators. Alkali-activated cement is a type of binder that exerts the same strength as cement without using cement by mixing industrial by-products with alkali activators. Alkali activators, which are used mainly for carbon-reducing technologies and alkali activation, are expensive and difficult to apply in the field due to risks related to strong alkalinity. Therefore, this study intends to explore methods to use red mud as a substitute for an alkali activator. To that end, this study has evaluated engineering properties, such as flow and strength, of CLSM that uses red mud and paper sludge ash as binders and its possibility to cause soil pollution. This study also aims to present the appropriate mixing ratios of red mud and paper sludge ash to produce CLSM.

Social infrastructures and industrial complexes have been actively constructed in South Korea since the 1960 s as part of the economic development plan, resulting in rapid industrialization. However, side-effects due to the industrialization have occurred. An increase in industrial by-products or wastes is a typical problem. Although some industrial by-products are recycled in Korea as well as worldwide, some wastes are landfilled or dumped in the sea. Although many researchers have executed various technologies for the disposal of industrial wastes, economic and environmental technologies have not been developed. Thus, this study aims to activate paper and fly ashes during the crush process to overcome the drawback of simple concrete mixed with paper and fly ashes, which cause a reduction in workability and strength, derive an optimal content and replacement ratio of concretes mixed with Energetically Modified Material (EMM), and evaluate the material performance. In addition, the basalt fiber is mixed simultaneously to achieve the reduction of cracks and improve the tensile strength.
