The purpose of this study was to evaluate the fitness of 4 kinds of resin record base materials. The record base materials used on the edentulous cast in this study were Triad VLC resin (Dentsply International Inc., U.S.A.), custom tray resin (Kerr Ltd., U.S.A.), heat-cure resin (Dentimex Co., Holland), and self-cure resin (Dentimex Co., Holland). The gap width between record base and cast were measured in the ridge crest and midpalatal area with microhardness tester. The results obtained were as follows : 1. Among the 4 kinds of record base, heat-cure Vertex fitted best on the cast. Triad and Fomatray fitted better than self-cure Vertex. Self-cure Vertex had the poorest fit. 2. The quality of the fit of the record base varied at different locations on the cast. The record base fit better in the ridge crest than midpalatal area. 3. In the midpalatal area, there's no significant difference in the fit of Fomatray, Triad and heat-cure Vertex. They all fit better than self-cure Vertex. 4. In the ridge crest, heat-cure Vertex fit better than any other record base.

This paper aims to introduce the basic concept of probabilistic record linkage and its statistical framework, and describe the specific process and principle of performing it using a real example from Statistics Korea. First, we briefly describe the deterministic record linkage and compare it with probabilistic record linkage. We introduce the Fellegi-Sunter model framework for record linkage and the related paprameters: m-probability, u-probability, matched weight and decision rule. Finally, we show the detailed process of record linkage under Fellegi-Sunter model framework and evaluate the record linkage results, using sample data from the registered-based census and Population and Housing Census survey in Statistics Korea.

Statement of the problem. The record base in fabricating procedures of the complete denture, as a temporary form for reproducing denture base, is used to record upper and lower jaw relation and to align artificial teeth and try-in it in the mouth. The accuracy of jaw relation record is affected by the accuracy, stiffness and stability of the record base. So, the accuracy of record base is the most important requirements of jaw relation records. Purpose of study. The purpose of this study was to evaluate the gap that occurred over the palatal area of a maxillary record base fabricated with autopolymerizing resin and light-curing resin. Methods/material. The maxillary record bases were fabricated out of autopolymerizing resin that is used the most frequently in clinics and light-curing resin that attracts special attention for its several merits. The light-curing resin was made by two kinds of polymerization methods, which are one step curing method and multiple step curing method. All record bases were cut in certain positions of the master cast 1 hour and 1 day later after fabrication and the accuracy of the master cast was measured and analyzed with a microscope. Results. A pattern of gap formation between the record base and the maxillary cast was observed in all specimens. According to kinds of resins, autopolymerizing resin was significantly more accurate than light-curing resin. There was no statistical difference according to time lapse, and in all three groups, the maximum discrepancy occurred at the posterior border in the mid-palatal region. Conclusion. The autopolymerizing resin is better than light-curing resin, and multiple step curing method is more accurate than one step curing method when using light-curing resin.

In this study, crash situations of representative bus crash types were elicited by analyzing a total of 1,416 bus repair record which were collected in 2018~2019. K-means clustering was used as a methodology for this study. Bus repair record contain the information of repair term, type of bus operation, responsibility of accident, weather condition, road surface condition, type of accident, other party, type of road and type of location for each data. Also, by checking collision parts of each bus repair record, each record was classified by types of collision regions. From this, 760 record are classified to frontal type, 363 record are classified to middle-frontal type, 374 record are classified to middle-rear type and 331 record are classified to rear type. As mentioned, k-means clustering was performed on each type of collision parts. As a result, this study analyzed the severity of bus crash based on actual bus accident data which are based on bus repair record not the crash data from the TAAS. Also, this study presented crash situation of representative bus crash types. It is expected that this study can be expanded to analyzing hydrogen bus crash and defining indicators of hydrogen bus safety.

This study investigates and analyzes the 16th Presidential records (record management secretary's office) from a record-recognition perspective and, based on the results, suggests the Presidential record management plan. To this end, the function of the records management secretary's office was first analyzed, and the 16th Presidential records transferred to the Presidential Archives were reviewed from a general perspective. Next, the nature of the records was investigated in a deductive, top-down manner by quantitatively analyzing the "production system type," "preservation period," "reason for determining the retention period," "management department," "electronic record type," "production year," etc., focusing on the "records file/item," "unit task," and "function." Finally, the characteristics and problems revealed during the record analysis were summarized. Based on the analysis results, a plan was proposed to redesign Presidential record management for the "reorganization" and "service" parts of the records.

Recently, distribution of record via web and coefficient of utilization are increase. so, Archival information service using website becomes essential part of record center. The main point of archival information service by website is making record information retrieval easy. It has need of matching user's request and representation of record resources correctly to making archival information retrieval easy. Archivist and record manager have used various information representation tools from taxonomy to recent thesaurus, still, the accuracy of information retrieval has not solved. This study constructed record retrieval system based on Topic Map by modeling record resources which focusing on description metadata of the records to improve this problem. The target user of the system is general web users and its range is limited to the president related sources in the National Archives Portal Service. The procedure is as follows; 1) Design an ontology model for archival information service based on topic map which focusing on description metadata of the records. 2) Buildpractical record retrieval system with topic map that received information source list, which extracted from the National Archives Portal Service, by editor. 3) Check and assess features of record retrieval system based on topic map through user interface. Through the practice, relevance navigation to other record sources by semantic inference of description metadata is confirmed. And also, records could be built up as knowledge with result of scattered archival sources.

This study reinterprets the meaning of the record contents from the viewpoint of the record continuum to find ways to enhance the usability of records that are emphasized by the electronic record environments. In general, in academic discussions and practical examples, record contents are recognized as digital media produced by putting a high level of computer technologies and a big budget based on some records related to specific subjects. To enhance the usability of, and spread the meaning through, records, it is necessary to shift the awareness in record contents. For this purpose in Chapter 2, to grasp the meanings of the church records as well as the utilization direction, it is necessary to analyze the organization and function. Therefore, the analysis of the organization and function of the church was examined. In Chapter 3, this study attempted to find the meaning of the contents of church records in each dimension of the record continuum in relation to the mission of the church, which was identified through the organization and function analysis of the church. In Section 3, which corresponds to Dimension 4, the meaning of church record contents is diversified in society. In the end, this study suggests that the meaning and use value of records can be found in everyday life and can then be spread to society as well.

In this paper, we aim to estimate two scale-parameters of exponentiated Pareto distribution (EPD) based on lower record values. Record values arise naturally in many real life applications involving data relating to weather, sport, economics and life testing studies. We calculate the Bayesian estimators for the two parameters of EPD based on lower record values. The Bayes estimators of two parameters for the EPD with lower record values under the squared error loss (SEL), linex loss (LL) and entropy loss (EL) functions are provided. Lindley's approximate method is used to compute these estimators. We compare the Bayesian estimators in the sense of the bias and root mean squared estimates (RMSE).
