This paper made a comparative study on domestic and international game archives that preserve and study the history of games. Based on that, it suggests the structure to classify and build a database to establish a history museum of games. The objective to gather and preserve history of games is mainly in order to build a baseline for ludology studies, but not solely for that reason. This study proposes the series of procedures of gathering, preserving, classifying, displaying and referencing digital games according to the academic field of Media Archaeology.

Video indexing plays an important role in the applications such as digital video libraries or web VOD which archive large volume of digital videos. Video indexing is usually based on video segmentation. In this paper, we propose a software tool called V2Web Studio which can generate video clips utilizing shot boundary detection algorithm. With the V2Web Studio, the process of clip generation consists of the following four steps: 1) Automatic detection of shot boundaries by parsing the video, 2) Elimination of errors by manually verifying the results of the detection, 3) Building a modeling structure of logical hierarchy using the verified shots, and 4) Generating multiple video clips corresponding to each logically modeled segment. The aforementioned steps are performed by shot detector, shot verifier, video modeler and clip generator in the V2Web Studio respectively.

In digital environment the hallmark of the national libraries is its responsibility or function of acquiring and preserving the county´s off-line and on-line publications in term of legal deposit. But the legal deposit system based on print materials in Korea predates the digital age and requires a new legal framework. It would be a tragedy if national library was not to archive the nation´s intellectual and cultural heritage because of limitation of legal deposit system. The purpose of this paper is to analyze form of the current deposit system and to suggest a reform model for legal deposit legislation with priority given to legal scheme and elements(terms, the depositor, the depository, object of deposit, number of copies, time of deposit, compensation and fine, right of migration and free access, etc.).

Reinforcement cells are used to aid grass growth and taken together, this serves to extend greenery beyond the conventional spaces of lawns, tree pits, gardens, and parks, and is advantageous to urban cities since space for greening is often limited. Drought has variable effects on plant life and the resilience of turf to drought resistance also varies with species. Changes in photosynthetic ability were more pronounced for media rather than grass species. The media of sand without organic matter was found to be least suited for drought resistance. Normalized difference vegetation index (NDVI) and digital image analysis (DIA) data were generally in favour of Zoysia species as oppose to A. compressus. In A. compressus, selective traits such as, a more extensive root system and lower specific leaf area (SLA) were not an underlying factor that assisted this grass with enhanced drought resistance. Generally, WUE was found to be strongly related to plant characterises such as overall biomass, photosynthetic features as well as the lushness indexes, and specific leaf area. This study found a strong relationship between WUE and a suite of plant characteristics. These traits should serve as useful selection criteria for species with the ability to resist water stress.

In this paper we explain the definition and component of electronic records, and reestablish the principle of the preservation. Also we discuss the conceptual approaches and requirements for long-term preservation in an electronic environment. The preservation in digital environment is to protect itself of record identity with the reliability and authenticity, and to ensure the accessibility of records. It needs to be periodical migration along with digital environment change for the long-term preservation of the electronic records. and to select software independent standard format. to ensure the integrity of electronic records along with this preservation strategy, process and relative information required for digital preservation are to record in the form of metadata. The preservation system is separated into four functional entities ; registration process, preservation process, access process, main record management system. Also, this article is conceptually to introduce the selection criteria of storage media, the security provision for the archive collections and the disaster recovery which apply to the digital archives.

The purpose of this study is to investigate the current infrastructure of database on costume cultural heritage. The contents, kinds and accessibility regarding the digital contents of the websites of literature archives, museums and culturecontent.com by Korea Creative Content Agency were analyzed. First, it was evident that the quantity and quality of the database should be improved. The literature archives are mostly comprised of historical documents; however, the quantity of the database regarding the documents that are commonly studied in the field of traditional costume is not satisfactory. On the other hand, the quality of the database depends on the in-depth understanding of the terminology because errors occur when the contents of literature are transferred to an online database. Second, various information is required to meet the needs and interests of the digital environment. Most of the museums provide information on costume cultural heritage through their websites; nevertheless, it is not thorough and only partial. Third, the reliability of information needs to improve. The various contents provided by culturecontent.com lack reliability as it focuses on the entertainment values. To increase reliability, the source and origin of the information about the costume cultural heritage should be provided and the contents should be proofread before they are exposed to the public. Based on these findings, the researchers put forward the following suggestions: the quantity and quality of the databases should be enriched, and that more diverse information is required. Finally, more attention should be paid to increase the reliability of this information. This study will be an asset for the foundation to build solid databases and popularization of the traditional costumes.

Record management, especially in schools as an institution's information centre, needs serious attention from government agencies. Under record management policy, there needs to be practical guidance on record management specific to schools. This paper aims to construct a record management model based on the Eight Indonesian Education Standards to support school accountability in Indonesia. The urgency of this paper in filling the gap in the Electronic Record Management System (ERMS) role is primarily to support school accountability. It is important to include educational laws and regulations in Indonesia to be a foundation in archive management, including preparing the ERMS. This study aims to develop a model of record management in schools. The final stage in this research is to find the final model. The final model is a model that experts and practitioners have validated. A total of 30 records managers were selected for the interviews. Furthermore, the trial was carried out in 30 senior high schools. The research sampling consisted of representatives of archive managers at selected schools from five islands in Indonesia (Kalimantan, Java, Papua, Sumatra, and Sulawesi). Our research findings show that conceptual models meet valid criteria and significantly impact archivist performance in better schools. The practical implication is that the archival management model based on national education standards policies contributes to practical archives and records management to support school accountability.

A control scheme for stand-alone inverters that utilizes an inductor current observer (ICO) is proposed. The proposed method measures disturbance load currents using a current sensor and it estimates the inductor current using the ICO. The filter parameter mismatch effect is analyzed to confirm the ICO's controllability. The ICO and controllers are designed in a continuous-time domain and transferred to a discrete-time domain with a digital delay. Experimental results demonstrate the effectiveness of the ICO using a 5-kVA single-phase stand-alone inverter prototype. The experimental results demonstrate that the observed current matches the actual current and that the proposed method can archive a less than 2.4% total harmonic distortion (THD) sinusoidal output waveform under nonlinear load conditions.

It is common for archive libraries to provide public access to historical and ancient document image collections. It is common for such document images to require specialized processing in order to remove background noise and become more legible. Document images may be contaminated with noise during transmission, scanning or conversion to digital form. We can categorize noises by identifying their features and can search for similar patterns in a document image to choose appropriate methods for their removal. In this paper, we propose a hybrid binarization approach for improving the quality of old documents using a combination of global and local thresholding. This article also reviews noises that might appear in scanned document images and discusses some noise removal methods.
