In the Hive file format, the sk(Security Key) cell provides access control to registry key. An attacker can figure out secret information on registry or change the security set-up if she could apply modified hive files on system. This paper presents various methods to change access control of registry key by modifying or replacing cell on hive file. We also discuss threats by access control modification and signs of attacks analysis by modified hive files.

The growing global energy demand has been the motivation for innovations for improved approaches on energy trade. The involvement of new energy market players known as prosumers have also enabled Peer-to-Peer (P2P) energy trade in microgrid communities. In this paper, a novel approach to energy trading based on Hive Strategy is proposed. The strategy aims to encourage prosumers to become workers that will meet the energy demands of consumers referred to as hives. The workers are selected based on their Prosumer Ratings (PR) and are ranked from the ones with the highest PR to the lowest. Using the PR, prosumers with the best energy consumption and generation behaviors are prioritized for energy trade. To test the proposed strategy, a simulation has conducted and the results show how the energy demand of the hive is met by the workers. Furthermore, an improvement in the pay-offs and PR of the workers are observed.

This study was conducted to determine the carcass rates, partcarcass production percentages, nutrient contents and optimum prices of broilers and old layers as related to the body weight. Total 240 birds were used and results obtained are summarized as follows. 1.The carcass rates were 61.41% in young chickens (0.6-0.8kg), 65.07% in semi-bros(1.2-1.4kg) and 66.39% in high- bros (1.7-2.1kg), showing a trend of increased carcass rate as the body weight increased. The carcass rates of old layers were lower than those of broilers, being 62.68% in white old lavers (1.8-2.0kg) and 63.07% in colored old layers (2.1- 2.4 kg) 2. Although there was little difference in part-carcass production percentages between breeds or body weights of broilers, most of the part-carcass was produced from legs, breast, back, wings and neck in order. 3. As the body weight increased, the moisture content of deboned carcass of broilers decreased (71.27% in young chickens, 62.66% in semi-bros and 60.39% in high-bros), while the fat content increased (11.47% in young chickens, 17.60% in semi-bros and 19.87% in high-bros). The protein content of semi-bros (17.21%) was higher than that of young chickens (14.75%) or high-bros (16.93%), but no difference was noted in old layers whether they were white or colored. 4. When compared on the basis of protein or Protein plus fat content in grams per kilogram body weight, the market price of semi-bros per kilogram body weight was more expensive and that of old layers was cheaper than that of high- bros.

A large volume of continuously growing BGP data files can raise two technical challenges regarding scalability and manageability. Due to the recent development of the open-source distributed computing infrastructure, Hadoop, it becomes feasible to handle a large amount of data in a scalable manner. In this paper, we present a new Hadoop-based BGP tool (BGPdoop) that provides the scale-out performance as well as the extensible and agile analysis capability. In particular, BGPdoop realizes a query-based BGP record exploration function using Hive on the partitioned BGP data structure, which enables flexible and versatile analytics of BGP archive files. From the experiments for the scalability with a Hadoop cluster of 20 nodes, we demonstrate that BGPdoop achieves 5 times higher performance and the user-defined analysis capability by expressing diverse BGP routing analytics in Hive queries.

HYBE Insight, opened in May 2021, is an exhibition space that visually displays and re-interprets the BTS Universe and its content. The space echoes the identity of BTS as an artist and the specificity of the cultural phenomenon they have generated. This study analyzes HYBE Insight's BTS exhibition by applying new museological theories and discourses. Based on a qualitative research methodology including literature review and observational method, the primary themes of the exhibition are follows: 1) a contextualized exhibition content presenting the identity of BTS and their music, 2) the role of the fandom Army's participation in (re) producing BTS content related to the characteristic of popular music museums, 3) the elements of convergence art and its contemporary implication, 4) and the illumination of cultural value in popular music museum management. As the pivotal theory of new museology suggests, investigating a specific exhibition based on each context it has created is significant. However, those studies, including exhibitions related to popular music/artists, were mostly developed in Western nations. In this respect, HYBE Insight's BTS exhibition provides considerable room to explore. In addition to the recent research on BTS, such as their convergent artistry, socio-cultural influence, the role of Army, and the characteristics of HYBE's content management, this article aims to contribute to the multifaceted research by scrutinizing the BTS exhibition content from the new museology perspective.

In the age of global competition, city brand is a significant element for establishing a city's competitiveness. City branding is the process of building a storytelling about cities' content. Among the various contents that differentiate cities, this study seeks to discuss the role of an event and a city brand in the process of city branding based on the city marketing and event tourism literatures. This research uses grounded theory and a case study to examine Seoul exploring the changes in the Hi Seoul Festival and the Hi Seoul city brand over the last two decades. The qualitative research includes a secondary data analysis based on case studies from domestic and foreign regions and their festivals. The analytical results indicted three limitations: inconsistency, a lack of identity, and political leverage. Based on the limitations, this study discusses the importance of the connection between city identity and event content, suggesting implications for moving forward toward a stable Seoul city branding strategy for the Seoul Metropolitan Government.

In this paper, we introduce an application virtualization method that could be supported without changing and modifying any resources and execution environment on host system, using non-installable portable software format that could be executed by one-click on any host without installing process. For the purpose of designing and implementing an application virtualization method, we construct virtual supporting system that includes virtual file system and virtual registry hive on kernel level of Windows operating system. Also, when users execute portable software on any hosts to provide consistency on using portable software, we describe method of processing information of appending and modifying files and registry datum on virtual file system and virtual registry hive through Copy-on-Write scheme.

Big Data is now seen as a major asset in the company's competitiveness, its influence in the future is expected to grow. Companies that recognize the importance are already actively engaged with Big Data in product development and marketing, which are increasingly applied across sectors of society, including politics, sports. However, lack of knowledge of the system implementation and high costs are still a big obstacles to the introduction of Big Data and systems. It is an objective in this study to build a Big Data system, which is based on open source Hadoop and Hive among Big Data systems, utilizing POS sales data of small and medium-sized offline markets. This approach of convergence is expected to improve existing sales systems that have been simply focusing on profit and loss analysis. It will also be able to use it as the basis for the decisions of the executive to enable prediction of the consumption patterns of customer preference and demand in advance.
