현대인은 급격한 사회변화와 발전 속에서 기회의 불균등으로 인해 인간성 상실과 갈등이 심화되고 있다. 이를 해결하기 위한 방법으로 인성교육의 필요성이 제기되고 있다. 이에 유아교육현장에서 쉽게 접 할 수 있는 그림책을 활용한 체계적이고 구체적인 인성교육 활동이 영유아의 자아존중감과 바람직한 인성 교육에 어떠한 영향을 미치는지 연구를 통해 인성 교육 방법을 제시하고자 한다. 따라서 본고는 유아가 그림책을 통해 자연 스럽게 감정을 표현하고 자신의 정서를 조절하는 인성프로그램 개발 및 바람작한 인성교육 활성화 방안을 모색하고자 한다.

Among ammunitions which are stored in a war field, the lifespan of propelling gunpowder is affected by storage environment such as storage temperature, humidity, and exposure to sunlight. These are because Nitrocellulose (NC) which is the main component of propelling gunpowder can be naturally disassembled to unstable substances similar with other nitric acid ester. We can’t prevent it fundamentally from being disassembled, but to restrain induction of automatic disassembly by decomposition product, a decomposition product (NO2, NO3, and HNO3) and tranquillizer DPA (Diphenylamine), having high reactivity, are added into a propellant. For this, it will decrease the velocity of tranquillizer which can also affect the velocity of producing the decomposition product of NC, storage temperature or humidity of propelling gunpowder is higher, drop of tranquillizer content is much faster. Therefore, to extend storage lifespan of propelling gunpowder, it is really important to control storage temperature or humidity inside the magazine. Hereupon, according to the manufacture of small scale model magazine and the result of performing experiments and measuring variation of inside temperature(storage temperature), using roof types that have a steel slate structure of magazine among ground magazines, this research shows the differences in details.

The revitalization of e-business via Internet brings big changes to the postal business, and leads to a tremendous increase of heavy and large sized postal mails with continuing growth of home delivery business. Thus, even though the number of intermediate storages for mail delivery that mailmen use for picking up mails in the middle of mail delivery has been being increased, it has still many problems such as insufficient number and size of the storages as well as avoidance of mail keeping of trust agents. It is necessary that safety of mail keeping, seamless mail delivery, and individual parcel pick-up process reestablishment should be made through an improved counter plan for the problems described previously. This study presents the efficient and right operational plan for the intermediate storage for mail delivery with providing the number and size of intermediate storages per mail delivery sequence according to four different types of post offices.
