Objective of this research is to point out problems of geographic division structure in current Korean Decimal Classification System and provide solutions. For this purpose key classification methods were divided to decimal and non-decimal classification methods and analyzed for geographical division principles. In addition, national institutes regional division standards from Korea, USA and Japan were researched. Through these analysis, we provided suggestions to improve the table of geographical division in KDC4 including public institutions administrative district classification structure relations and consistency, and other regional divisional standards (proposal) instead of typical administrative district reflecting various geographical conditions.

In this paper, the numerical simulation of the method of characteristics for a two-stroke SI engine was carried out, and the scavenging efficiency and the performance of single engine with two types of exhaust system, that is, a pipe exhaust system and a tuned exhaust system, were predicted and compared. The conculusions are obtained as follows. (1) The method of characteristics of hometropic flow considering the friction and the variation of area is useful to predict the scavenging efficiency and the performance of the two-stroke engine. (2) The shape of exhaust system effects directly on the scavenging and the trapping efficiency. (3) A tuned exhaust system consisted of the diffuser and the convergent nozzle makes the plugging pulse and therefore enhances the scavenging and the trapping efficiency. (4) It may be possible to design the optimum exhaust system by using the plugging pulse.

By the progress of informatization, the data which is involved in the administration and public organizations are increased the requestion of the utilization. Nevertheless most of the agencies could not actively participate in sharing and opening the data to the public because of data quality problems. The purpose of this study is to verify the relationship for data quality, managerial and organizational factors which is to derive at the level of the organization's data quality management success factors suggested in previous studies, and the acceptance of the organization's quality management. The result identify that organizational factors, organization's data quality management encouragement and support, give effect data quality through the acceptance of data quality management. However, managerial factors was no effect the data quality management acceptance. This study than managerial approach when considering the quality control for the public organizations, in the early days of the current situation of a company-wide consensus was required, as well as directly to the level of quality factors affecting the quality of acceptance is presented to derive but has significance.

Although numerous studies have noted the importance of data sets in government information systems, the practical management of data sets has yet to be developed. Under these circumstances, the National Archives of Korea designated data set management as a major project in 2020, initiating full-scale management work. Despite these efforts, the records center, which will conduct management, expressed great concern for the new project. As such, this study identifies problems in managing data sets and searches for possible improvements through a comparison with existing public data projects by public institutions. In particular, the following materials were analyzed: laws, notices, guidelines, and publications issued by the ministries. Based on the results, several measures were proposed as part of an improvement plan for data set management: (1) the utilization of government functional classification as a reference, (2) the reorganization of the table, and (3) data linkage with related systems.

The new administrative capital construction project is an important national project implemented to relocate the national administrative capital, and the records produced during the construction have high historical value. However, Korea's management of these records related to the construction of the new administrative capital is insufficient; thus, finding a management plan is necessary. In contrast, Brazil is a country that collects, builds, and maintains both public and private records produced during the construction of Brasilia, the new administrative capital. Thus, Arquivo Publico do Distrito Federal (ArPDF), the Brazilian records management organization established to manage Brasilia's construction records, was selected as the case analysis subject in this study. By analyzing ArPDF's website and official publications, this study investigated the overall matters related to the management of new administrative capital construction records and derived implications applicable to the management of new administrative capital construction records in Korea.

Purpose: This study was conducted to provide basic data necessary to develop a program to improve infection control by examining nurses' perception of accreditation and by identifying its relationship with awareness and performance of infection control. Methods: This cross-sectional study was performed using questionnaires. Data were collected from 210 nurses who were working at one hospital between May 14 and May 19, 2015. Data were analyzed using SPAW. Results: The mean score for nurses' perception of accreditation was 3.10 points out of 5 points. Score for awareness of infection control was $4.63{\pm}0.39$ points and for performance of infection control, $4.39{\pm}0.39$ points. There were significant positive correlation among perception of accreditation, awareness of infection control, and performance of infection control. In the regression analysis, performance of infection control was influenced by awareness of infection control which accounted for 42.6% of the variance. It also showed additional improvement of 1.4% of the variance by when perception of accreditation was added. Conclusion: The result of this study show that nurses' perception of accreditation is relatively positive and that performance of infection control is highly enhanced according to nurses' positive recognition of accreditation as well as attaching importance to accreditation.

Recently, fuel prices have been continually raised in diesel engine. Such a change in the fuel price influences enormously the development trend of marine diesel engines for slow speed, In other words, the focus was shifted from large diameter and high speed to low fuel consumption. Accordingly, more efforts are being made for engine manufacturing and development to develop highly efficient engines. In this study. a single cylinder 4 stroke cycle DI slow speed diesel engine was designed and manufactured, a 4 stroke cycle was configured and basic performances were evaluated. The results are as follows. The optimal fuel injection timing had the lowest value when specific fuel consumption was in BTDC 8~$10^{\circ}$, a little more delayed compared to high speed diesel engines. Cycle variation of engines showed about 5% difference at full loads. This is a significantly small value compared to the cycle variation in which stable operation is possible, showing the high stability of engine operation is good. The torque and brake thermal efficiency of engine increased with an increase of engine 250-450 rpm. but fuel consumption ratio increased from the 450 rpm zone and thermal efficiency abruptly decreased. Mechanical efficiency was maximally 70% at a 400 rpm that was lower than normal engines according to the increase of mechanical frictional loss for cross head part. The purpose of this study was to get more practical engines by comparing the above results with those of slow speed 2 stroke cycle diesel engines.
