Cloud collection, which is derived from cloud computing, is a framework that creates new value through library cooperative platform to preserve and manage libraries' duplicated collection. Due to E-book market vitalization and mass digitalization of retrospective print material, new library collection management paradigm has been expected that licensed based E-book service and management of shared print repository. This study discuss cloud collection concept which digital repository and Shared print repository are in complementary relations. And suggest cloud collection model can be applicable to Korean university libraries.

In this paper, we propose a stack allocation technique of Android Java objects in order to reduce the number of garbage collection which is one of major reason on Android performance degradation when running applications. The proposed technique is to allocate Java objects into stack rather than heap memory. To do so, stacked objects could escape the garbage collection process. We experiment the proposed technique in the latest Android 2.3 version. For the simulation, we take advantage of the well known Java benchmark, Caffeinemark, and our own. The result shows the performance degradation of Dalvik Virtual Machine execution time caused by the stack allocation of Java objects is very slight and the proposed method considerably reduces the frequency of garbage collection. This will increase application performance and give better user interfaces to Android phone users.

The purpose of this study was to first look at genderless concepts that are different from Unix, and by grasping the trend of genderless clothes in modern fashion and examining their characteristics, we looked at genderless trends and characteristics in modern fashion. To this end, this study conducted a theoretical review and collection case analysis through domestic and foreign literature and fashion websites. Based on this, the characteristics of genderless clothes expressed in the collection were derived by analyzing designs with strong genderless tendencies in modern collections. As a result of the study, genderless fashion in modern collections could be derived from three visible results: innovation, rebellion, and future-oriented. In addition, modern genderless fashion contains various needs for mental gender and physiological gender, not simply physiological gender, and this is seen by interacting with the current social phenomenon in which gender distinction becomes ambiguous. Understanding and studying the genderless phenomenon, which has become a cultural phenomenon and popularity, hopes that many follow-up studies related to genderless clothes will be conducted in the future.

The purpose of this paper is to grow more interest and to forster research in full-texts retrieval of digitized books area through the review of Book Search Track and the analysis of research methods. First, this paper introduces the INEX tracks, the registration of INEX, the task process and the participating organizations. Second, to introduce the Book Search Track of all INEX tracks, this paper provides an overview of the test collection, the tasks, the task and submission guidelines and evaluation results of the Book Search Track's. Third, through paper review of the Book Search track that was lunched in 2007 as part of the INEX initiative, this paper presents the future research subject. This study expects that the readers are attracted by INEX tracks and full-texts retrieval of digitized books in korea.

Storage device based on Flash Memory have many attractive features such as high performance, low power consumption, shock resistance, and low weight, so they replace HDDs to a certain extent. An Storage device based on Flash Memory has FTL(Flash Translation Layer) which emulate block storage devices like HDDs. A garbage collection, one of major functions of FTL, effects highly on the performance and the lifetime of devices. However, there is no de facto standard for new garbage collection algorithms. To solve this problem, we propose File Clustering Algorithm. File Clustering Algorithm respect to update page from same file at the same time. So, these are clustered to same block. For this mechanism, We propose Page Allocation Policy in FTL and use MIN-MAX GAP to guarantee wear leveling. To verify the algorithm in this paper, we use TPC Benchmark. So, The performance evaluation reveals that the proposed algorithm has comparable result with the existing algorithms(No wear leveling, Hot/Cold) and shows approximately 690% improvement in terms of the wear leveling.

디지털 TV, 셋톱박스, 홈 서버 등 정보 가전 분야에서 Java 기술을 적용하는 범위가 확대되고 있지만, 현재 Sun 의 JVM 이나 공개용 Kaffe VM 등의 경우에 스케줄링 측면이나 가비지 콜렉터의 관점에서 실시간 조건을 고려하고 있지 않기 때문에 실시간 응용 분야에 바로 적용하기에는 문제점을 갖고 있다. 특히, 가비지 콜렉터의 측면에서는 가비지 회수 동안 응용 프로그램의 수행을 중지시키는 stop-the-world 방식으로 진행되어 응답 시간 및 실행 시간 계측 불가로 인해 실시간 시스템에 적합하지 않다. 따라서 작은 단위의 가비지 컬렉션 기능과 응용 프로그램의 수행을 병행하는 점진적(incremental) 가비지 콜렉터의 설계가 필요하다. 본 논문에서는 가비지 콜렉터의 관점에서 실시간 특성을 보장하는 점진적 가비지 컬렉션 방법에 관해 살펴본다.

The purpose of the study is to implement the digital archives to document environmental conflicts using open source Omeka. Mi-ryang Transmission Tower Construction Conflict is the selected case because it is very crucial and continues until today for more than 10 years. It begins with analyzing domestic and international cases of archives developed using Omeka. Based on these analysis, it draws the directions of developing Mi-ryang archives. It also investigates and analyzes the Mi-ryang conflicts as the contexts of records creation, acquire the actual records from a Mi-ryang civic group, and finally implement the collections and exhibits of Omeka-based archival system.

This article is an overview of the digital library project, indicating what roles Korea's diverse digital collections may play. Our digital library prototype has simple architecture, consisting of digital repositories, filters, indexing and searching, and clients. Digital repositories include various types of materials and databases. The role of filters is to recognize a format of a document collection and mark the structural components of each of its documents, We are using a database management system (ORACLE and ConText) supporting user-defined functions and access methods that allows us to easily incorporate new object analysis, structuring, and indexing technology into a repository.

RRecords management has focused largely on public records in south korea with a relatively low progress in the collection and management of private records with the enactment of Public Records Act in 1999. This study set out to categorize the records of the Coalition for Democratic Reunification and the People's Movement(DRPM) and develop them into a group collection. For this study, literature reviews, analysis and reorganization of records content, development of a classification system, and expert evaluation were carried out. The findings of this study will contribute to greater efficiency in the search of records about the DRPM by developing a classification system to recategorize its records of various sources and enable their easy access and utilization in a digital archive. In addition, the basic structure of producer-oriented classification can be suggested as an example of the organization of a group collection.
