This study is one of a series of studies exploring the locality of Jeju architecture, in which we focused on the works of domestic architects, rather than those of famous foreign architects, as well as on the locality of the phenomenological aspect rather than the conceptual one, so as to reveal the locality in the present situation. It was revealed that the architects had the following viewpoints with regard to the local characteristics of Jeju: first, the hermeneutic aspect of the locality is the architectural application of the traditional Jeju architecture; second, the phenomenal aspect of the locality involves respect for the landscape and natural scenery of Jeju. There are two main ways in which architects can realize the locality that they envisage. The hermeneutic representation of Jeju would be as a locality consisting of traditional houses. The architects mainly wanted to implement the elements of the private houses through the space layout. The phenomenal representation of the locality would require them to respect the landscape and scenery of Jeju and to implement them in its architecture. This was the case if the landscape or landscape elements were directly borrowed from the buildings, or if the buildings respect the scenery or landscape of Jeju.

One of the major issues of DBMS is the buffer management. Because fetching data from the database disk is costly, the number of disk I/O's must be minimized in order to improve the DBMS performance. Although there have been many buffer management strategies to minimize the disk I/O, those strategies usually focused on just the temporal locality. Since there are the spatial locality as well as the temporal locality in the spatial database, strategies using only the temporal locality cannot achieve the optimal performance in the spatial database. In this paper, we propose a new buffer management strategy, the Spatial Locality Area Measure(SLAM) strategy, that considers not only the temporal locality but also the spatial locality. The SLAM buffer management strategy consists of two core structures, the SLM-tree and the M-LRU. We show the efficiency of the proposed strategy through experiments over various buffer sizes and reference frequencies.

This paper is a study on locality in architecture in Jeju with the theme of locality of architecture. This paper, as the last research paper in this series of studies, is a paper that verifies whether there is anything other than the locality revealed in the categories of 'hermeneutic' and 'phenomenal'. To this end, in this paper, the regional characteristics of the buildings of five Jeju IT companies were analyzed. As a result, the elements reflected in the architecture in terms of the locality of Jeju were quite insufficient. This can be seen as a result of the fact that the corporate image is important in terms of the architecture of an IT company. Nevertheless, if we summarize the elements that reflect the characteristics of Jeju in IT architecture, it is the wind and oreum used as architectural concepts, and Jeju stone used as the exterior finish. In conclusion, it could be seen that the regional characteristics of wind, oreum, and Jeju stone were used in IT architecture, and it was also found that these characteristics were within the scope of interpretive locality and phenomenal locality. Soon, it was found that the locality of Jeju architecture was within the hermeneutic and phenomenal category.

To speed up data-intensive programs, two complementary techniques, namely nested loops parallelization and data locality optimization, should be considered. Effective parallelization techniques distribute the computation and necessary data across different processors, whereas data locality places data on the same processor. Therefore, locality and parallelization may demand different loop transformations. As such, an integrated approach that combines these two can generate much better results than each individual approach. This paper proposes a unified approach that integrates these two techniques to obtain an appropriate loop transformation. Applying this transformation results in coarse grain parallelism through exploiting the largest possible groups of outer permutable loops in addition to data locality through dependence satisfaction at inner loops. These groups can be further tiled to improve data locality through exploiting data reuse in multiple dimensions.

When the volume of data grows big, some simple tasks could become a significant concern. Nearest neighbor search is such a task which finds from a data set the k nearest data points to queries. Locality-sensitive hashing techniques have been developed for approximate but fast nearest neighbor search. This paper introduces the notion of locality-sensitive hashing and surveys the locality-sensitive hashing techniques. It categories them based on several criteria, presents their characteristics, and compares their performance.

Temporal locality of Web server references is one of the important characteristics to be considered in the design of a Web caching strategy, and it is important to measure the temporal locality exactly. Various methods to estimate the temporal locality have been proposed, however, Web server designers have still troubles in its measurement by using the tools that don't reflect the interarrival time of document requests. In this paper, we propose a measurement tool for short-term temporal locality based on request interarrival time, and discuss the simulation results based on the flares from NLANR and NASA Web sites. The results show that the proposed tool estimates the short-term temporal locality more exactly than that based on a stack.

In this paper, we propose a very efficient reversible data hiding algorithm using spatial locality and the surface characteristics of image. Spacial locality and a variety of surface characteristics are present in natural images. So, it is possible to precisely predict the pixel value using the locality and surface characteristics of image. Therefore, the frequency is increased significantly at the peak point of the difference histogram using the precisely predicted pixel values. Thus, it is possible to increase the amount of data to be embedded in image using the spatial locality and surface characteristics of image. By using the proposed reversible data hiding algorithm, visually high quality stego-image can be generated, the embedded data and the original cover image can be extracted without distortion from the stego-image, and the embedding data are much greater than that of the previous algorithm. The experimental results show the superiority of the proposed algorithm.

The purpose of this study is to suggest new methodologies for documenting locality in digital environment, reformulation the Cox's documentation model focused on cooperative acquisition of documentary heritage institutions. This study defines the concepts of locality, space and place, relation of collective memory to archives, and analyzes the four approaches of documentation comparatively. Based on these analyses, it suggests the categories of documenting locality, and the directions of archive portal design for collective memory of locality.

Efficient buffer management is closely related to system performance. Thus, much research has been performed on various buffer management techniques. However, many of the proposed techniques utilize the temporal locality of access patterns. In spatial database environments, there exists not only the temporal locality but also spatial locality, where the objects in the recently accessed regions will be accessed again in the near future. Thus, in this paper, we present a buffer management technique, called BEAT, which utilizes both the temporal locality and spatial locality in spatial database environments. The experimental results with real-life and synthetic data demonstrate the efficiency of BEAT.

This study was conducted in Tateyama, Japan with on-site observation conducted by Professor Aizawa, who organized this locality movement. This research was focused on listening to people's explanations, observations and studying the related documentation. First of all, the locality of Tateyama City was formed by utilizing the historic records of the area. Through Namo Amitabha which was carved on the four-sided stone pagoda, the city formed the locality as the peaceful city. "The gift of the Sea" painted by Shigeru Aoki in this city contributed to the identity of this locality known as the 'city of art which the painter loved'. The reconstruction of localities through the documentation of the relics are as follows. Satomi Castle, which was discovered to be the setting of the famous fictional saga Satomi and the Eight "Dogs". The excavation and research of the ruins of forgotten World War II, is another example of reconstruction at this locality. This locality is seen as 'the city of peace' and was reconstructed through a positive and future oriented attitude. It is noticeable that the locality of Tateyama city was newly formed or reconstructed using local records and documentation relics in the area.
