Casual games are often have simple rule and easy to play. Like Angry birds, players can sling a bird as a bomb to destroy target. But the film adaption encounters numerous questions. games in pursuit of strong sensed presence, pay attention to experience; film stress the integrity of the story, attaches great importance to plot. However, casual games don't have story and plot. This paper take angry birds as example, analyzes the difficulties and method of adaptation from leisure mobile games to films, summarizes the key successful elements of adaption, such as subdivided the target group, chose an appropriate genre, write a script follow the basic logic and frame of film, set contradiction, complicated the character and still contain key elements of the game, in order to provide new ideas in the future development of integration of game and movie industry.

Modem society is information oriented with countless people needing quick reliable information. They also wart to be freed from the limitations of reality such astime and space and experience the world of imagination as if it was reality. Design is creating something out of nothing which has an innate sense of virtual within it. Since it is a process of bringing an imagingnation or an image to life, it can be described as the realization of virtuality. there are many ways in which computer adapted methods were utilized for design up to now. With the advance of computers, the process of desinging became efficient, visually complex and much easier. Undoubtedly, computer is a powerful hardware an design and furthermore, find a way to maximize the presence and to actively incorporate this in designing. The virtual reality system can be widely applied to environmental design to provude a high quality design and enhance the feeling of reality through imitation experiments. Computer simulation such as virtual reality systems is expected to be used widely in environmental design.

본 연구에서는 국내는 물론 전 세계적으로 널리 사용되고 있는 SWAT 모형을 대상으로 하천 단면 관련 입력변수가 유량 및 수질 모의에 미치는 영향을 분석하였다. 본 연구에서는 남한강 상류 충주댐 유역을 연구대상지역으로 연구를 진행하였으며, 충주댐 유역 내 소유역 중에서 국립환경과학원에서 국내 하천을 대상으로 구축한 한국형 Reach File(KRF) 내 실측 하천단면 정보가 존재하는 소유역에 대하여 실측 하천단면 정보를 적용하였다. 또한 본 연구를 위해 사용자가 구축한 소유역별 하천단면 정보 입력 자료를 통해 수문 및 수질 모의가 가능하도록 기존 SWAT 모형의 엔진 소스코드를 개선하였다. 유역 최종 유출구와 KRF의 실측 하천단면 정보를 적용한 소유역의 유량과 수질(유사량)에 대해서 실측 하천단면 정보 적용 전과 후의 모의 결과를 비교한 결과 유역 최종 유출구에서는 유량 및 유사량 모두 큰 변화는 나타나지 않았다. 이는 전체 유역 중 실제 하천단면 정보를 적용한 소유역의 비중이 작기 때문으로 판단되었다. 하지만 하천단면 정보를 적용한 소유역에서는 유량 및 유사량 모두 적용 전/후 차이가 나타났다. 특히 저유량 부분에서의 유사량이 큰 변화를 나타냈다. 하지만 본 연구에서 실측 하천단면 정보를 적용한 소유역은 유량 및 수질관측소가 위치하지 않는 미계측 유역으로써 실제 유량 및 수질 모의 정확도 향상 여부에 대한 평가가 불가능하였다. 따라서 향후 유량 또는 수질 관측이 이뤄지고 있는 계측 유역을 대상으로 실제 모형 모의 정확도 향상 여부에 대한 분석이 필요할 것으로 판단된다.

This essay deals with The Homeric Hymn to Demeter, a aetiological myth about the Eleusis Mysteria. The narrative of the hymn shows how Demeter, the goddess of grain, became the deity of the Mysteria. In the hymn, Demeter is characterized as a mother: She is the mother of Persephone and the motherlike nurse of Demophone. As the mother of Persephone and Demophone, the roles of are nursing and mediating. She care her children and linked the earth and the world below, the heaven of gods and the earth of mortals. Demeter the deity of the Mysteria by a mother. The and the maternity of Demeter is connected with patriarchal politics. Demeter in the hymn is not so much the goddess who derived her character from The Great Mother as the goddess who had been characterized the influence of Greek-patriarchy.

In this study, we introduced the development status and the government policy of the Chinese automobile industry under the rapidly changing global economic environment. We conducted a consumer trend survey on automobile purchases by consumers in China. Despite the Chinese government's strong national emission control policy and stricter standards for manufacturing and selling internal combustion engine vehicles, 59.6% of respondents saying they would choose an internal combustion engine vehicle when purchasing a vehicle in the future for various reasons. It was confirmed that there is a significant gap between government policies and consumer perceptions. In addition, we have discovered the recent declining trend of automobile sales in China, and used the monthly sales volume from January 2010 to December 2020 as training set, and the sales volume from January 2021 to November 2022 as a test set. We proposed and evaluated a time-series model for predicting future automobile demand in China. Then, we showed the monthly sales forecast for 2023 when each model was applied.

In the coming future, anyone using the Internet will have more than one NFT. Unlike FT, NFT can specify the owner, and tracking management is easier than FT. Even in the 2022 survey, WPA2 is the most widely used wireless protocol worldwide to date. As it is a protocol that came out in 2006, it is a protocol with various vulnerabilities at this time. In order to use WPA2-EAP or WPA3 (2018), which were released to compensate for the vulnerabilities of WPA2, additional equipment upgrades are required for STA (station) and AP (access point, router), which are connected devices. The use of expensive router equipment solves the security part, but it is economically inefficient to be introduced in Small Office Home Office (SOHO). This paper uses NFT as a means of authentication and uses the existing WPA2 as it is without equipment upgrade, defend crack tools of WPA2 that have been widely used so far and compared to the existing WPA2, it was shown that it was not difficult to actually use them in SOHO.

It is very time-intensive to obtain data with labels on anomaly detection tasks for multivariate time series. Therefore, several studies have been conducted on unsupervised learning that does not require any labels. However, a well-done integrative survey has not been conducted on in-depth discussion of learning architecture and property for multivariate time series anomaly detection. This study aims to explore the characteristic of well-known architectures in anomaly detection of multivariate time series. Additionally, architecture was categorized by using top-down and bottom-up approaches. In order toconsider real-world anomaly detection situation, we trained models with dataset such as power grids or Cyber Physical Systems that contains realistic anomalies. From experimental results, we compared and analyzed the comprehensive performance of each architecture. Quantitative performance were measured using precision, recall, and F1 scores.

전 세계적으로 기후변화 및 산업화로 인해 대규모 홍수, 가뭄, 폭염, 산불 등의 재해가 빈번하게 발생하고 있으며, 이러한 재해 및 재난을 조기에 발견하고 최소화를 위한 대응 체계 및 관리방안의 필요성이 증대되고 있다. 이러한 자연재해들의 특징은 추가 재해를 유발할 수 있다는 것으로 재해의 강도가 증가할 뿐만 아니라 여러 가지 재난 및 재해를 동시에 유발하는 형태로 변화하기 때문에, 단일자연재해 평가 기술을 바탕으로 복합자연재해에 대한 분석 및 감지가 진행되어야 한다. 최근 기후변화로 인한 기상 패턴의 변화 및 가뭄 발생빈도의 증가가 뚜렷하며, 국외에서는 폭염과 가뭄을 고려한 복합자연재해로 'Flash Drought'로 정의된 돌발가뭄에 대한 연구가 이루어지고 있다. 폭염과 가뭄은 단순 강우 부족으로 인한 가뭄, 높은 기온으로 인한 폭염 등이 서로 독립적으로 발생하는 경우와 강우부족과 폭염의 지속으로 인한 상호연관성이 존재하는 복합자연재해 등으로 구분할 수 있다. 돌발가뭄은 강수 부족 또는 폭염이 지속되거나 강도가 높아질 경우, 지면온도가 상승하여 토양수분이 필요 이상으로 증발하여 단기간에 발생하는 초단기 가뭄으로 복합자연재해에 해당하며, 이러한 돌발가뭄은 농업분야에서 작물 생장 및 영농기 활동에 큰 영향을 미치기 때문에 모니터링 및 감지 기술이 필요하다. 본 연구에서는 수문기상학적 요소를 활용하여 폭염 및 가뭄을 고려한 복합자연재해에 대한 상관분석을 수행하였다. 기상청에서 제공하는 기상자료(일최고기온/평균기온/최저기온, 강수량, 상대습도, 일조량 등)에 대한 전국 76개소 대상 기상자료를 구축하였으며, Sentinel, Landsat, MODIS(Moderate Resolution Imaging Spectroradiometer) 등과 같은 위성영상 자료를 구축하여 폭염과 가뭄에 대한 각각의 인자를 선정하고 상관 관계를 분석하였다. 본 연구의 결과는 향후 복합자연재해 감지 및 예측 기술 개발에 활용하여 재해 예방 및 대응에 대한 기초자료로 활용될 수 있을 것으로 판단된다.
