This study aims to extract key topics through text mining of incident records (incident history, post-incident measures, preventive measures) from construction safety accident case data available on the public data portal. It also seeks to provide fundamental insights contributing to the establishment of manuals for disaster prevention by identifying correlations between these topics. After pre-processing the input data, we used the LDA-based topic modeling technique to derive the main topics. Consequently, we obtained five topics related to incident history, and four topics each related to post-incident measures and preventive measures. Although no dominant patterns emerged from the topic pattern analysis, the study holds significance as it provides quantitative information on the follow-up actions related to the incident history, thereby suggesting practical implications for the establishment of a preventive decision-making system through the linkage between accident history and subsequent measures for reccurrence prevention.

Necessity to install control towers has been studied to acquire overseas energy resources and to secure funds. At present, domestic energy companies do business independently. Institutions which support plant EPC companies as partners of package deal are separated. This causes the low records at package deal for overseas resources acquisition. Except UK and USA, nations which have major companies developed overseas energy resources early by promoting a large national company. Consequently, they currently have good records. This study suggests the necessities to install integrated control tower for overseas energy resources acquisition and securing funds and the following are the ways ; 1) promote a large national company by consolidation of separate energy companies, 2) install plant EPC promotion department which support private plant EPC companies, 3) make a integrated control tower in high level government office to connect between a large national company and plant EPC promotion department.

A wavelet-based procedure to generate artificial accelerograms compatible with a prescribed seismic design spectrum is described. A procedure to perform a baseline correction of the compatible accelerograms is also described. To examine how the frequency content of the modified records evolves with time, they are analyzed in the time and frequency using the wavelet transform. The changes in the strong motion duration and input energy spectrum are also investigated. An alternative way to match the design spectrum, termed the "two-band matching procedure", is proposed with the objective of preserving the non-stationary characteristics of the original record in the modified accelerogram.

The Equipment Expenses section of the Poom-Saem, that is used for Construction Cost Estimation on public sectors in Korea, has been rarely revised, and so does not reflect changes of construction equipment technology and construction methods, since it was established based on data from Japan and the U.S in the early 1960s. In order to make reasonable estimation of maintenance costs(Interest, Storage, Insurance, Tax), the equipment expenses section of the Poom-Saem and the domestic and overseas documentary records were investigated. Further, 16 construction sites were visited, and 20 Construction Equipment leasing services were surveyed. Based on results from analysing figures related with the estimation of maintenance costs, the maintenance cost is redefined. Then, construction equipment was classified into 6 exclusive construction equipment and general one, and realistic figures of the maintenance cost, which consists of interest, storage, insurance, tax, are suggested respectively. The optimum level of each item which consists of equipment costs was revealed based on the result of the analysis on the figures of equipment costs calculation from the Poom-Saem and the collected data. The research will be the foundation that helps to estimate appropriate construction costs and the ground work of related studies.

Global construction market has grown rapidly since 2000. Even though developing countries grew into an economic, the most of oil-producing countries of continuous high oil prices due to an increase in plant construction orders is to present a lot of influence. According to the growth of global construction market, the domestic construction companies in the overseas market share have recorded 3% of the performance of the top 10 world records. However, current performance has analyzed the expansion of the market rather than competitiveness development of domestic construction companies. Therefore, to improve competitiveness in the global construction orders for the domestic construction companies in terms of long term, the government in Korea has ordered various research projects related to the plant since 2005. This paper presents not only global plant market trends and plant project in domestic but also introduction of completed research standardization recently.

The classification scheme of records indicates a table that intends to express organic relations between records by organizing records and enabling internal order. Although the principles of organic classification have remained in traditional records management environment, they have been changed to "function and business" in the modern times. Therefore, Korea introduced a business reference model (BRM) based on function and business from 2008 and subsequently implemented its operation. However, it has been pointed out that the roles of the classification scheme of records have not been played because the analysis of "Danwigwaje," which belongs to the lowest level of business reference models, is poor. According to this indication, the Gangbuk District of Seoul Special City established a functional classification scheme by executing a business process analysis of "Danwigwaje." First, the record manager carried out analyses on the principles of "Danwigwaje," small function, and "Danwigwaje." Then, the functional classification scheme of "Danwigwaje" was modified by looking into the opinion inquiry process of the treatment department and performing a test operation. Through the case of the Gangbuk District in Seoul Special City, analytical procedures and methods of "Danwigwaje," as well as implications according to the establishment of a functional classification scheme of basic local governments, were arranged in a written format.

The importance of long-term preservation of various types of electronic records through dark archives is gradually increasing. However, the current dark archive does not have an optimized information package structure for long-term preservation of electronic records. In order to address these problems, this research proposed four element categories by re-organizing the OAIS reference model information package based on the core process of the dark archiving. The detailed descriptive items of each category consist of a total of 4 upper-level elements and 27 sub elements based on the OAIS reference model, ISO 23081, Records Management Metadata Standard, ISAD(G), ISAAR(CPF), ISDF, and ISDIAH. This structure can be used as a basis for constructing an information package optimized for dark archiving, and is expected to support the long-term preservation of electronic records more efficiently.

Jeongamsa Sumano Stupa(Korean National Treasure No. 332) is a brick like stone stupa and it is considered that this stupa was built in the Later Silla period or in the early part of the Koryo period, considering its structure and style. This Buddhist stupa is highly significant in Korean Buddhism since it was built to enshrine Buddhist sarira reliquaries that 'Jajang' brought from China in the 7th century, according to the 『Overlooked Historical Records of the Three Korean Kingdoms, 『三國遺事』』. However, the stupa was positioned at the very unique location. It was positioned not at the center of Jeongamsa Temple, but at the separate edifice. The location of Jeongamsa Sumano Stupa indicates that this stupa embodies the nature of Mahaparinirvana treasure palaces and that this stupa was recognized as a solemn symbol, which reflected a sarira faith. Jeongamsa Sumano Stupa is the only brick stone stupa built in Gangwon province. It is worth noticing that this stupa was mostly made of dolostones, found around this region, and thereby regional characteristics were reflected in this stupa. The other interesting fact about Jeongamsa Sumano Stupa is that there are many records available which include information about stupa's reconstruction, considering that there aren't many records of other stupas. The most representative records are 5 pieces of memorial stones which include information about when and on what ground the stupa was reconstructed as well as information about originators of the stupa. In conclusion, Jeongamsa Sumano Stupar could be regarded as the academically valuable material since it is considered very important and helpful for understanding not only the history of Korean Buddhist stupas, but also so many other things such as construction techniques, styles of brick pagoda and brick stone stupa, and such.

In a new technological environment such as big data and AI, LOD will link record information resources with various data from both inside and outside. At the heart of this connection is the interlinking technology, and interlinked LOD will realize the opening of record information as the highest level of open data. Given the ever-increasing amount of records, automation through interlinking algorithms is essential in building LODs. Therefore, this paper analyzed the structure of record information interlinking with the external data and characteristics of the record information to be considered when interconnecting. After collecting samples from the CAMS data of the National Archives, we constructed a record information's LOD. After that, we conducted a test bed that automatically interlinks the personal information of the record metadata with DBPedia. This confirms the automatic interlinking process and the performance and accuracy of the automation technology. Through the implications of the testbed, we have identified the considerations of the record information resources of the LOD interlinking process.

Objectives: An accurate estimation of cancer patients is the basis of epidemiological studies and health services. However in Korea, cancer patients visiting out-patient clinics are usually ruled out of such studies and so these studies are suspected of underestimating the cancer patient population. The purpose of this study is to construct a more complete, hospital-based cancer patient registry using multiple sources of medical information. Methods: We constructed a cancer patient detection algorithm using records from various sources that were obtained from both the in-patients and out-patients seen at Asan Medical Center (AMC) for any reason. The medical data from the potentially incident cancer patients was reviewed four months after first being detected by the algorithm to determine whether these patients actually did or did not have cancer. Results: Besides the traditional practice of reviewing the charts of in-patients upon their discharge, five more sources of information were added for this algorithm, i.e., pathology reports, the national severe disease registry, the reason for treatment, prescriptions of chemotherapeutic agents and radiation therapy reports. The constructed algorithm was observed to have a PPV of 87.04%. Compared to the results of traditional practice, 36.8% of registry failures were avoided using the AMC algorithm. Conclusions: To minimize loss in the cancer registry, various data sources should be utilized, and the AMC algorithm can be a successful model for this. Further research will be required in order to apply novel and innovative technology to the electronic medical records system in order to generate new signals from data that has not been previously used.
