자녀 교육에 대한 관심의 증대로 다양한 미디어를 활용하여 많은 유아 교육용 프로그램이 상용화되어 있다. 그 중 스마트폰의 활용 분야가 넓어지면서 자연스럽게 유아 교육 분야도 스마트폰에 접목이 되고 있는 추세이다. 본 논문에서는 동화책을 읽어주는 행위와 90년대 초중반에 유행했던 게임북을 스마트폰에 접목시켜 자녀와 부모가 함께 할 수 있는 유아 교육용 어플리케이션 설계를 제안한다. 본 논문의 어플리케이션은 동화를 보는 중 스토리 중간 중간 간단한 미니게임 및 문제 선택 결과에 따라 본래의 동화 스토리 또는 허구 스토리 동화로 진행되어 다양한 엔딩을 볼 수 있다. 또한 동요듣기, 악기다루기, 율동 배우기, 스트레칭 등 여러 옵션을 제공한다.

21C future learners are required to have creative thinking and problem-solving capability to address an issue wisely by integrating and applying knowledge and functions. The robot education that has recently been studied in primary and secondary schools was reported to be effective in satisfying the requirements. The robot education varies ranging from the existing after-school education to an integrated approach used for regular curriculums, and has actively been studied. Nevertheless, aside from positive study results, any studies on the environment where primary school students can learn robot and programming knowledge more friendly is still insufficient. Therefore, this study was intended to give students a robot class with the use of storytelling friendly to students in order for primary school students to learn robot and programming knowledge with ease. The study result showed that acquirement of programming knowledge was improved, and that the students had a positive learning attitude. In addition, it was found that the storytelling of the robot class helped provide the entire learning context and continuous learning motivation for the students.

낸드 플래시 메모리는 하드 디스크와는 다른 여러가지 특성 때문에 논리 주소를 불러 주소를 변환해 주는 주소 변환 계층(FTL)이 필요하다. 최근에 고성능의 저장 장치를 제공하기 위해서 페이지 수준의 주소 변환 기법이 많이 사용되고 있는 데, 이 기법은 매핑 정보가 너무 커서 메모리에서 매핑 정보를 관리하기에는 힘들다는 문제와 데이터의 접근 지역성을 잘 활용하지 못하는 문제가 있다. 본 논문에서는 스토리지의 주소 공간을 유닛이라는 단위로 분리하여 페이지 수준의 주소변환을 사용함으로써 매핑 정보를 크기를 줄이고 또한 접근 지역성을 활용하여 가비지 컬렉션 오버해드를 줄이는 유닛 레벨 주소 변환 기법을 제시한다. 실험결과 제시한 기법은 페이지 매핑 기법보다 랜덤 접근 패턴에서 가비지 컬렉션 오버해드를 40% 감소시켰으며 매핑 데이터 량도 38% 감소시켰다.

그리드 기반 대규모 신약후보물질탐색환경에서는 (1) 대규모의 도킹 작업을 그리드 상에 제출한 후 이들을 지속적으로 관리하고, (2) 실행된 각 작업들은 동시에 그리드 스토리지 및 메타데이터 카탈로그 서비스에 접근한다. 우리는 위의 두 부분에서 성능의 개선이 필요함을 발견하였다. (1)의 과정에서 제출된 작업의 상태 정보를 얻기 위해 그리드 스케쥴러를 사용하던 기존의 방식은 대규모 작업 제출에 의한 부하 문제로 정확한 정보를 신속하게 얻는 데 어려움이 있어 제출된 작업의 효율성이 떨어지는 문제가 있었다. 그리고 (2)의 과정에서는 동시에 실행된 대규모 작업들의 접근 요청이 그리드 스토리지 및 메타데이터 카탈로그 서비스에 집중되면서 이로 인해 성능 저하가 일어났다. 본 연구에서는 기존 환경에서 찾아낸 위의 두 가지 주요 부분에서 발견한 성능 이슈를 밝히고 또 이에 대한 해결 방법을 제시한다.

Game contents are the driving force of the digital media era. As the gaming industry grows bigger, contents technologies are also rapidly developing in both their quality and quantity, while the story sources of the contents are depleting. Accordingly, digging out new stories that can support development of the cultural contents industry is emerging as an urgent issue. Since games took roots as a form of contents in our society, negative images have outweighed positive aspects. This study aims at finding cures for the side effects from storytelling. Important factors here are how to converge the technical nature of engineering imagination and the epic nature of humanities imagination. Recently, The excavations of the story is very important. This article demonstrates cases where the oral literature, an archetypical cultural genre, provides the sources of game storytelling.

Most of the robot programming curriculums consists mainly of understanding robot programming language and learning a simple grammatical sentences rather than logical problem solving process, these curriculums impose a burden on childrens' learning. Storytelling offers opportunities for continuation of childrens' positive learning motivation to practice symbolic manipulations, hold multiple abstract concepts in their heads, and create meaning between these ideas. In this paper, to overcome the difficulty of robot programming curriculum in elementary school and find teaching method which derives the childrens' motivation, we used storytelling in study of our robot programming curriculum.

Real life has been actively utilizing storage from anywhere automobiles and Aviation field etc to the development of storage. Recent Big Data is stored as a number of data storage and data distribution processing emerged in research has been actively conducted to process the data. But many bottlenecks or processing speed slows down when you request the data at the same time a problem arises. In this paper consider should be used in the field of big data storing and processing large amounts of data, the process data more efficiently when the number of data request and data suggest that the weight-effective, manageable data processing system algorithm.

A video is a vivid medium similar to human's visual-linguistic experiences, since it can inculcate a sequence of situations, actions or dialogues that can be told as a story. In this study, we propose story learning/regeneration frameworks from videos with successive event order supervision for contextual coherence. The supervision induces each episode to have a form of trajectory in the latent space, which constructs a composite representation of ordering and semantics. In this study, we incorporated the use of kids videos as a training data. Some of the advantages associated with the kids videos include omnibus style, simple/explicit storyline in short, chronological narrative order, and relatively limited number of characters and spatial environments. We build the encoder-decoder structure with successive event order embedding, and train bi-directional LSTMs as sequence models considering multi-step sequence prediction. Using a series of approximately 200 episodes of kids videos named 'Pororo the Little Penguin', we give empirical results for story regeneration tasks and SEOE. In addition, each episode shows a trajectory-like shape on the latent space of the model, which gives the geometric information for the sequence models.

A cloud service customer has no other way but to wait for his lost data to be recovered by the cloud service provider when the data was lost or not accessible for a while due to the provider's system failure, cracking attempt, malfunction, or outage. We consider a solution to address this problem that can be implemented in the cloud client's domain, rather than in the cloud service provider's domain. We propose a high level architecture and scheme for successfully retrieving data units even when several cloud storages are not accessible at the same time. The scheme is based on a clever way of partitioning and partial overlapping of data for being stored on multiple cloud storages. In addition to providing a high level of data availability, the scheme makes it possible to re-encrypt data units with new keys in a user transparent way, and can produce the complete log of every user's data units accessed, for assessing data disclosure, if needed.

Recently, the interest among Korean broadcasters in the 'observation entertainment' genre has intensified. This study aims to analyze the genre and storytelling of observation entertainment programming from a narratological perspective. The origin of the Korean observation entertainment program began with the 'reality-variety show'. There was a 'real-life' debate in these reality-variety shows, and as an alternative, the observation entertainment program appeared. Documentary filming, omnibus composition, and spatialization of 'everyday' life have led to the recognition of observation entertainment as a single genre. In particular, 'observers' have become a key factor in the observation entertainment program. The subject of the program is determined by who the observer is. The variability of the program format is the same. The observer looks at the observation target on behalf of the viewer. At the same time, he or she serves as a narrator of the program. The observer functions as the most influential factor in the storytelling of the observation entertainment program. In the observation entertainment program, 'observation' is only a form. It is the observer who creates a narrative within this same format to make the difference between each program. Also, voyeurism has been considered a problem in reality shows such as observation entertainment programs. However, the form communicated by observers is not a direct peek, so much of the problem of voyeurism is mitigated. Such observation entertainment programs analyzed through observers are meaningful in that they make people understand the cultural meaning of "reality" in TV and the storytelling of contemporary Korean TV entertainment.
