The purpose of this study is to confirm meaning for quest-based learning designed as one of learning methods with new media, which the contents were made of QR code based on smart-phone. For this purpose, this study conducted 8 times of class during one month with 32 elementary third graders. And analysis for the result of this study was carried out MANOVA focus on four sub-factor of motivation. The results showed positive effect for quest-based learning in attention and confidence factor on motivation. Quest-based learning of gaming version as a learning method using various media can use a learning method for facilitation of learner participation, supporting of learning by doing.

The public has only a superficial understanding of the computer games, in spite of it's psychological effects and social results. Therefore, in this study, one finds out the serious approach which leads the computer games to recognize its future in terms of new media. Stand-point from Freud to french post-structuralist, it helps the introduction to understand the computer games as a kind of contents in which we are able to observe psychological process. As a result, there are studies about the structure of the dream, the desire, and the language which allow to mention 'parmakon' ; 'difference' between self and object, it provokes the psychological dynamism and so on, the playing the game remains a real trace and change, at the level not only of our psyche but also of our body.

BEC (Business Email Compromise) attacks are frequently occurring by impersonating accounts or management through e-mail and stealing money or sensitive information. This type of attack accounts for the largest portion of the recent trade fraud, and the FBI estimates that the estimated amount of damage in 2019 is about $17 billion. However, if you look at the response status of the companies compared to this, it relies on the traditional SPAM blocking system, so it is virtually defenseless against the BEC attacks that social engineering predominates. To this end, we will analyze the types and methods of BEC accidents and propose ways to effectively counter BEC attacks by companies through AI(Artificial Intelligence).

National Institute of Korean History(NIKH) is the major collecting organization of manuscripts, records for historical research and develops a Collecting Manuscripts Management System. Manuscripts description conforms to records management system, such as provenance information and hierarchical catalog records and business process observes library management system because it is not the public records. Goal system is integrated system containing both. This study proposes development of Collecting Historical Manuscripts Management System in the NIKH and the aspects to achieve successful system operation.

To analyze the characteristics of bacteriophages in Enterococcus faecium, D-19 and F6 phages were induced from five E. faecium isolated from sprouts by the treatment with mitomycin C. The bacteriophages of D-19 and F-6 had long, non-contractile tails and icosahedral heads, and were members of Siphoviridae family. As the host spectrum, D-19 phage lysed five out of 55 strains of E. faecium, whereas F6 phage lysed only three strains. Both D-19 and F6 phages displayed similar and high stabilities against ethanol and pH capable of resisting the exposure to 100% ethanol and pH 4.

This paper represents the multiple sensor fusion algorithm for the deep-sea unmanned underwater vehicles (UUV), composed of a remotely operated vehicle (ROV) 'Hemire' and a depressor 'Henuvy'. The performance of underwater positioning system usually highly depend on that of acoustic sensors such as ultra short base line(USBL), long base line(LBL) and altimeter. A practical sensor fusion algorithm is proposed in the sense of a moving window concept. The performance of the proposed algorithm can be observed by applying the algorithm to the Hemire sea trial data which was measured at the East Sea.

The development of network and the other communication-network can generate serious problems. So, it is highly required to control security of network. These problems related secu be developed and keep up to confront with anti-security part such as hacking, cracking. Th way to preserve security from hacker or cracker without developing new cryptographic algori keeping the state of anti-cryptanalysis in a prescribed time by means of extending key-length In this paper, the proposed montgomery multiplication structured unit array method in carry generated part and variable length multiplicator for eliminating bottle neck effect with the RSA cryptosystem. Therefore, this proposed montgomery multiplicator enforce the real time processing and prevent outer cracking.

The goal of this research is contemplation on whether postmodern design concepts such as parody, simulation, appropriation, pastiche apply to the character design in games, within bounds of postmodernism. In this philosophy, designs display a mixture of advanced culture and mass culture, emphasize philosophical contingency, and appear to be a random collage of ideas. it was perceived that the visual art in game character design is also a projection of the postmodernist philosophy. Upon analyzing this perception, character designs categorized based on the applicability of postmodern designs

A hologram is a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation. Therefore not only can it express the three dimensional properties of the object, but because of it ability to show the depth and spatial properties of the object holograms may be a more effective tool in advertising for its visual appeal. This study presents 'hologram'a three dimensional stereo imaging, as the expression technique in advertising of the next generation, and with proper understanding of 'hologram' and of all its potential applications discusses opportunities for advertisements that are distinct from the multi media advertisements of today. The basic concept of Holograms and their application methods were presented in the thesis, and by using Sales Promotion advertisement as example, discussed what elements are required in order to produce an effective advertisement using holograms.

최근 들어 염해, 콘크리트의 탄산화, 동결융해 등의 열화요인 의하여 발생할 수 있는 콘크리트의 내구성에 대한 다양한 연구가 진행되고 있는데, 이러한 열화요인은 독립적이 아닌 복합열화의 형태로 작용하게 되는데, 열화현상을 저감하는 한 방편으로 플라이애쉬와 같은 혼화재를 사용하디도 한다. 플라이애쉬는 유동성 증진을 통한 내구성의 향상과, 수화열 저감을 통한 균열감소 및 장기강도 증진 등의 효과가 있으며, 시멘트를 대체함으로써 경제적인 효과를 유발하는 장점도 가지고 있다. 그러나 플라이애쉬는 품질편차가 크고, 경우에 따라서 미연탄소분에 의한 AE제 흡착 등으로 인한 콘크리트의 내구성 및 강도를 저하시킬 수 있는 요소를 내포하고 있으므로 사용 시 주의가 필요하다. 본 연구에서는 열화를 저감하고, 내구성을 갖는 고강도 콘크리트를 제조하기 위하여 다양한 배합비의 플라이애쉬 혼입 콘크리트를 실험한 후 그 결과를 분석·고찰함으로써 내구성 콘크리트의 제작 시 혼화재로서의 적용성 및 타당성을 검증하고자 하며, 플라이애쉬를 내구성 재료로 그 활용을 극대화하고, 다양한 플라이애쉬의 사용량과 물/결합재비(W/B)에 대하여 내구성이 높은 고강도 콘크리트 제조방법을 범용화하며, 그 품질을 평가하는 것을 목적으로 한다.
