Rammed Aggregate Pier method is intermediate foundation of deep and shallow foundation, it has been built on world wide. But the investigation and research in domestic is not accomplished. In this paper, examined details of different spacing of piles, bearing capacities, respectively, conclude with recommendations on how RAP can be used in future needs. This documentation further provides comparisons of the laboratory test results which were obtained from differenciate the spacing of piles, namely installed rammed aggregate pier. Strain control test was conducted to determine the bearing capacities of the piers; 20mm, 30mm and 40mm diameter drilling equipment to drill holes were installed in sand at initial relative densities of 40%. By comparing different spacing of piles, in this experiment, piles are spaced structually span, form a ring shape, narrowing the distance of each other, to the center. the result shows that as diameter of pier is bigger in diameter, bearing capacity also dramatically increased due to raised stiffness. Also, the space between each piers narrowed, settlement rate of soil was decreased significantly. From the test results, as the space between each piles were getting closer, allows greater chances to have resistance to deformation, shows improved stability of structures.

Gene Expression Omnibus (GEO) has kept the largest amount of gene-expression microarray data that have grown exponentially. Microarray data in GEO have been generated in many different formats and often lack standardized annotation and documentation. It is hard to know if preprocessing has been applied to a dataset or not and in what way. Standard-based integration of heterogeneous data formats and metadata is necessary for comprehensive data query, analysis and mining. We attempted to integrate the heterogeneous microarray data in GEO based on Minimum Information About a Microarray Experiment (MIAME) standard. We unified the data fields of GEO Data table and mapped the attributes of GEO metadata into MIAME elements. We also discriminated non-preprocessed raw datasets from others and processed ones by using a two-step classification method. Most of the procedures were developed as semi-automated algorithms with some degree of text mining techniques. We localized 2,967 Platforms, 4,867 Series and 103,590 Samples with covering 279 organisms, integrated them into a standard-based relational schema and developed a comprehensive query interface to extract. Our tool, GEOQuest is available at http://www.snubi.org/software/GEOQuest/.

문화 아카이빙은 최근 많은 관심을 받고 있는 주제이다. 문화가 경쟁력인 시대적 배경과 기록학의 영역 확장 때문이다. 이에 따라 일상 아카이빙이나 마을 아카이빙과 같은 다양한 시도들이 전개되고 있고, 많은 연구들이 이루어졌다. 그러나 당위성을 설명하거나 실제 사례들을 보여주는 연구에 치중되어, 문화 아카이빙에 필요한 이론적 연구는 상대적으로 이루어지지 못하였다. 이 글은 문화 아카이빙에 있어 기록의 문화적 재현 가능성을 이론적으로 검토해보고, 문화아카이빙의 과정을 제시하였다. 또한 문화 아카이빙에 있어서 기록관리자의 생산에 대해 재검토 하였으며, 수용자가 부여한 가치를 중심으로 한 방법론을 제안하였다. 이를 위해 콘텐츠에 적합한 분류체계 설정과 재현방식의 아카이빙을 검토하였다.

Purpose: This study evaluates the ability to improve the economic welfare of rural communities in Indonesia by using the inequality measures of the distribution of information between leaders and their people as a variable that weakens the capacity of increasing the welfare. Research Design, Data, and Methodology: The research designed by developing an instrument using data validity and reliability testing. Before, primary data collected through interviews, questionnaires, observation, and documentation on the selected respondents. Then, the research method used is mixed methods research, in which quantitative and qualitative methods combined. Result: The finding from this study is that there is an inequality measure in the form of a high gap between the score of information distribution obtained by the village government compared to the score of the community, which has led to the welfare of the village which is still at a moderate level and not ready to become a prosperous society. Conclusion: The weakness of the village community is related to two things, namely the behavior and knowledge of the community about the issues, so the implication is that there must be a strong effort from the central government to ensure that technology is more evenly distributed to all villagers.

Some regions and states, such as Wyoming, have harsh weather conditions, forcing most transportation projects to be completed under tight schedules. However, construction projects are not only delayed by weather conditions, but also delayed by other factors such as contractor's competency, resource availability, coordination issues, and safety. Also, the construction method, geographical location of the projects, and inability to follow baseline schedules accurately due to the contractor's resource allocation are also reasons for the delay. This paper discusses the main reasons for the delay in the public transportation projects based on Daily Work Reports (DWRs) from five different transportation projects of the last three years in Wyoming. This paper focuses on the inconsistencies of the contractor's schedules to complete the project according to the baseline schedule. First, the authors collected DWRs and baseline schedules from the Wyoming Department of Transportation (WYDOT). Second, the DWR data are compared against the baseline schedules to determine the reasons for delaying their significance. Finally, the paper presents the recommendations to mitigate the effects of delays on public transportation projects as well as to improve the documentation process of DWR data.

Software architecture are High-level design decisions shaping a software system's components, structure, and interactions. It can be a blueprint for development, evolution, and ongoing maintenance. This research investigates the communication practices employed by software architects and developers to ensure adherence to the designed software architecture. It explores the factors influencing the selection of follow-up methods and the impact of follow-up frequency on successful implementation. Findings reveal that formalized follow-up procedures are not yet a ubiquitous element within the software development lifecycle. While electronic communication, particularly email, appears to be the preferred method for both architects and developers, physical and online meetings are utilized less frequently. Interestingly, the study suggests a potential confidence gap, with architects expressing concerns about developers' ability to faithfully implement the architecture. This may lead to architects providing additional clarification. Conversely, while most developers reported confidence in their software knowledge, overly detailed architecture documentation may pose challenges, highlighting the need for architects to consider alternative communication strategies. A key limitation of this study is the sample size, restricting the generalizability of the conclusions. However, the research offers valuable preliminary insights into the communication practices employed for architecture implementation, paving the way for further investigation with a larger and more diverse participant pool.
