It is known that some amount of loss in impact energy takes place due to some limitations and problems during the performance of the field SPT. Actual energy level tractsferred to the rod should be measured to correct the SPT-N values tested in the field In this paper, the ratio of energy transferred to the rod through the anvil to impact energy is measured by using sharpy impact test equipment and also analysed by using GRL-WEAP This result is certified and compared with that of field SPT As the results of this study, the average rod energy ratio of the R-P hammer and the Trip hammer is calculated at 0.726 and 0.728 respectively, but it is suggested that 0.72 should be used. By using the hammer energy ratio 64.2% and 75.0% obtained from field measurement, the average energy ratio of the SPT for the R-P hammer is calculated at 46.7% and 54.5% for the Trip hammer.

Massive increases in data available to an organization are creating a new opportunity for competitive advantage. In this era of big data, developing analytics capabilities, therefore, becomes critical to take advantage of internal and external data and gain insights for data-driven decision making. However, the use of data in education is in its infancy, in comparison with business and government, and the potential for data analytics to impact education services is growing. In this paper, I survey how universities are currently using education data to improve students' performance and administrative efficiency, and propose new ways of extending the current use. In addition, with the so-called data scientist shortage, universities should be able to train professionals with data analytics skills. This paper discusses which skills are valuable to data scientists and introduces various training and certification programs offered by universities and industry. I finally conclude the paper by exploring new curriculums where students, by themselves, can learn how to find and use relevant data even in any courses.

S-57 is currently the IHO standard for the exchange of digital hydrographic data. S-57 is intended to support all types of hydrographic data. But, it has been used almost exclusively for encoding Electronic Navigational Charts(ENCs). In onder to meet this requirement, a new standard is being developed. GML will be the core encoding rule of IHO's new standard. but there has been no study that tried to develop the GML for ENC that are reconized as base map in the Marine GIS. If ENC is transformed into the form of GML, it may be widely used for more users and applications. This paper presents the application schema for translating ENC into GML and program.

Designing a complex begins with plans to differentiate the archetypical place in accordance with environmental characteristics of the area where target programs and districts are to be located, with which the space reformed with the change and development of the era is established and shaped. In particular, in the area such as our domestic land, some 70% of which is inclined has adopted the design concept that uses slopes with the stream of times and has sought design strategies that consistently interpret and approach slopes. Taegwondo Park, the target of this study, has collected six draft design plans during the design stage with different values and thus strategies of utilizing topographies and spaces differentiated accordingly. Particularly, approaching strategies in accordance with geographical features by designer, the relationship between architecture and external space to be implemented according to the rank, philosophical understanding of architects and design strategies as the concept of iconizing the area carry significant implications as major design strategies explored by this study, through which I was able to identify the possibility of materializing the design strategy for hill lands.

The amount of web traffic has increased as a result of the rapid growth of the use of web-based applications. In order to obtain valuable information from web logs, we need to develop systems that can support interactive, flexible, and efficient ways to analyze and handle large amounts of data. In this paper, we present CERES, a log-based, interactive web analytics system for backbone networks. Since CERES focuses on analyzing web log records generated from backbone networks, it is possible to perform a web analysis from the perspective of a network. CERES is designed for deployment in a server cluster using the Hadoop Distributed File System (HDFS) as the underlying storage. We transform and store web log records from backbone networks into relations and then allow users to use a SQL-like language to analyze web log records in a flexible and interactive manner. In particular, we use the data cube technique to enable the efficient statistical analysis of web log. The system provides users a web-based, multi-modal user interface.

The objectives of this study are to investigate core learning ability necessary for the 21st century and to develop core human resources required for social and national development in the future. The '21st Century Learning Ability Project' is to approach the existing knowledge and learning multidisciplinary and interactively based on the learning ability of each learner and individually and socially valuable themes. Even in Korea, a variety of intersubject integrative educational curriculum was attempted to cultivate learning ability. However, there are not enough teachers who can teach the differences between the content and characteristics for each subject by fully understanding them. Thus, it is difficult to apply them easily to the field of education. Thus, this study develops the multidisciplinary customized educational curriculum in order to develop the learning ability necessary for the 21st century, analyzes the reality of the educational curriculum integrating the academic knowledge in order to support this effectively. As a result, this study offers the interdisciplinary customized integrated model applicable to elementary and middle schools.
