“지난 2001년 4월 얼마남지 않은 자본금으로 무엇을 해야 하나 라는 고심 끝에 뛰어든 분야가 모바일 게임 개발이었습니다. 소자본, 새로움에 대한 열정, 기술에 대한 자신감, 팽창하는 시장의 가능성, 수금 걱정 없는 비즈니스 모델 등이 꼭 저희를 위해 만들어진 사업이란 생각이 들었습니다. 다행히 자신감과 오만함, 그리고 내면의 절치부심이 어우러져 홀로서기가 가능한 회사를 일구어 낼 수 있었습니다.”지난 2001년 12월 모바일 게임 시장에 뛰어든 모제스의 서대도 대표는 모바일 게임이야말로 그들을 위한 최적의 아이템이라고 생각했다. 그리고 그 생각은 지금도 변함이 없다. 창의성과 아이디어, 그리고 기술력만 있으면 충분히 시장에서 성공할 수 있다고 믿기 때문이다.

일반적으로 멀티 온라인 배틀 게임은 게임의 참가자들이 팀을 이루어 전략을 짜고 협력하여 주어진 목적을 성취하면 승리한다. 게임에서는 승리를 판가름 할 수 있는 다양한 요소(e.g. 골드, 아이템, 캐릭터의 레벨 등)들이 있다. 본 논문에서는 게임 플레이 중에 다양한 요소를 분석하여 실시간으로 승률을 예측할 수 있는 딥러닝 기반의 모델을 제안하고 이를 리그오브레전드 게임에 적용하여 그 결과를 분석하였다.

서로 다른 아이템 집합의 연관성을 분석하는 것을 연관규칙분석이라 한다. 대표적인 알고리즘으로 Apriori 알고리즘이 있지만 DB스캔 횟수가 많아질 수 있고 후보 집합 생성으로 인해서 속도가 느려질 수 있다는 단점이 있다. 이를 효율적으로 개선한 FP-Growth 알고리즘을 구현하여 임의의 데이터를 이용하여 알고리즘의 속도에 대해 연구한다.

With the increasing interest on K-fashion all over the world, it's the important time to create the items which can express the unique identity of Korea for promoting the globalization of Korean fashion. Accordingly, this study aims to suggest the modern applicability of traditional patterns by designing the bags using the Dancheong patterns(traditional multi-colored decorative painting) which can effectively express Korean images in a variety of shapes and definite visual features and then expand the scope of fashion items. To this end, this study concentrated on expressing the Dancheong patterns to fit to the modern fashion trends by re-interpreting them. The bag was designed using the laser cutting technique, without weaving or digital printing, to imbue the technical emotion and 3D effect to the patterns. In accordance with the analysis results, the features of patterns could be delicately expressed around the shaping and structuring method in terms of the design, and the scope of design for leather goods could be expanded using the laser cutting in technical aspects. For the industrial aspects, it is required to develop differentiated goods expressing the unique emotion of the Korean for globalization of Korean design.

Broadcast scheme has been widely researched for efficient data delivery in the mobile environment because the downlink capacity of a mobile client is much greater than the uplink capacity, and the power of a mobile client is limited. In the proposed scheme, the index lets the client know when data items would be broadcasted and enables the client to minimize the tuning time and power consumption. Single channel index schemes are fit to flat broadcast that performs well when all the broadcasted data items are accessed with the same probability whereas the multi-disk broadcast scheme is proper when the data access distribution is skewed. The existing index schemes, however, cannot work on the Multi-disk broadcast scheme because they cannot point the replicating data items in a broadcast cycle. This paper proposes a Multi-disk Exponential Index (MDEI) which is a single channel index scheme fit to Multi-disk broadcast scheme. Because MDEI scheme organizes a separate index for each disk, it functions with multi-disk broadcast, resulting in a greater reduction of average access latency than that of other flat-broadcast index schemes when the data access distribution is skewed. The performance evaluation showed that MDEI has a good performance when data access distribution is skewed. MDEI has short average access latency and not much average tuning time when the data access distribution is skewed.

This study is about developing an Android application that provides information on customized styling and the app was made to offer assistance in coordinating users' clothing. It keeps the record on clothing items users wore and uses it as coordination information, and prepares styling by referring to user-specific clothing management data. The photos can taken during shopping or can be taken from smart phone gallery, and the images searched through Daum OpenAPI can be saves in the app. Using the saved photos of items and clothes that were previously worn, the app provides styling recommendations.

As e-commerce developing rapidly, it is becoming a research focus about how to find customer's behavior patterns and realize commerce intelligence by use of Web mining technology. One of the most successful and widely used technologies for building personalization and goods recommendation system is collaborating filtering. However, collaborative filtering have serious data sparsity problem. Traditional association rule does not consider user's interests or preferences to provide a user with specific personalized service.In this paper, we propose an goods recommendation system, which is integrated an collaborative filtering algorithm with item-to-item corelation and an improved Apriori algorithm. This system has user's interests or preferences ro provide a user with specific personalized service.

The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities MPEG-21 Event Reporting is required within the MPEG-21 Multimedia Framework in order to provide a standardized means for sharing information about Events amongst Peers and Users. There are several Time used in MPEG-21 Event Reporting. In this paper, we analyze and categorize various kinds of Time used in Event Reporting. And we define ERTimeType to be applied for every. Time used in Event Reporting and implement it by XML to support interoperability of standard. The ERTimeType structure we defined is established its objectivity as it is selected to 'ISO/IEC 21000-Part IS: Event Reporting WD 2.0'.

The purpose of this study is to review the expanded role of authority files, which uses the Knowledge Organization System(KOS) to organize contents and manage the collections in digital libraries. The KOS plays a role as a bridge between the users' information needs and materials by providing links between catalogs and digital resources on the web and supporting retrieval of the relevant items. It is described how a KOS can be used to link a digital resource to related materials, to provide more descriptive records for entities, and access to relevant physical objects.

MPEG-21은 디지털 객체를 정의하고 이를 네트워크상에서 생성, 변형, 전달, 소비를 위한 통합적 멀티미디어 프레임워크에 대한 국제 표준이다. 디지털 아이템(DI: Digital item)은 MPEG-21 프레임워크 내에서 표준화 된 식별체계, 서술 형식을 따르는 구조화된 디지털 객체이며, 유통, 처리의 최소 단위이다 본 논문에서는 이러한 디지털 아이템을 최종 소비하는 MPEG-21 터미널 구조를 제안하고 이에 대한 설계 및 구현, 그리고 실험 결과를 제시한다
