This study introduces newly implemented geological well logs database for Jeju public water wells, built for a research project focusing on integrated hydrogeology database of Jeju Island. A detailed analysis of the existing 1,200 Jeju Island geological logs for the public wells developed since 1970 revealed six major indications to be improved for their use in Jeju geological logs DB construction: (1) lack of uniformity in rock name classification, (2) poor definitions of pyroclastic deposits and sand and gravel layers, (3) lack of well borehole aquifer information, (4) lack of information on well screen installation in many water wells, (5) differences by person in geological logging descriptions. A new Jeju geological logs DB enabling standardized input and output formats has been implemented to overcome the above indications by reestablishing the names of Jeju volcanic and sedimentary rocks and utilizing a commercial, database-based input structured, geological log program. The newly designed database structure in geological log program enables users to store a large number of geology, well drilling, and test data at the standardized DB input structure. Also, well borehole groundwater and aquifer test data can be easily added without modifying the existing database structure. Thus, the newly implemented geological logs DB could be a standardized DB for a large number of Jeju existing public wells and new wells to be developed in the future at Jeju Island. Also, the new geological logs DB will be a basis for ongoing project 'Developing GIS-based integrated interpretation system for Jeju Island hydrogeology'.

Standard Estimating System, which can be used for estimating a construction cost, has been pointed out having some problems such as non-reflecting a variety of construction environments and site conditions, non-adapting new technologies and methods since it was established in 1970. For solving these problems, the Korean Institute of Construction Technology(KICT) has chosen organizations for amending Standard Estimating System. However they have had many mistakes in the process of amending works because of non-establishing amending process and absence of the depreciation measurement method. This research derived the necessity to improve the amending process of the Standard Estimating System, and presented the detailed amending process and the performing method in the each process. Furthermore, this research proposed the depreciation measurement method available for the construction industry by means of analyzing researches that performed in the manufacturing industry and the measurement method for depreciation of general accounts.

The purpose of this study was to develop and evaluate a measuring scale for the effect of reading programs for children. First, in literature review, the effects and children's reading programs performance scales were analyzed, and then independent variables, dependent variables, and control variables for children's reading achievements were defined. Second, survey questionnaires for children, librarians, program instructors, and heads of child centers were designed to measure dependent variables and control variables on the scale. Third, the questionnaires for children were distributed to 10 public libraries participating in <2013 The Reading with Library> programs for two times in the early and the late time of the programs. Also, the survey questionnaires of 30 librarians, program instructors, and heads of the child centers were carried. Finally, all of the data were collected and analyzed in time series, and the improvements for the scale were proposed.

This study mainly focused on the development of real-time based damage investigation system using web-GIS. The study area was Gangseo-Gu in Busan where frequently has relatively higher magnitude of damages from natural disasters. GIS DB was built to provide geospatial data such as 1:1,000 and 1:5,000 topographic maps and IKONOS high resolution satellite data. The web-GIS system has demonstrated the higher contribution for the better response and recovery against any type of natural disasters through real-time communication and data dissemination among government agencies and personnel. However, further researches need to be made to improve system capabilities. In addition, for more effective system operation and maximizing the benefits of exploiting web-GIS system, linkage with national DB such as NDMS is essential.

The object of this research is to develop a computerized algorithm of cost estimation method to forecast the total construction cost in the bidding stage by the historical and elemental work cost data. Traditional cost models to prepare Bill of Quantities in the korea construction industry since 1970 are not helpful to forecast the project total cost in the bidding stage because the BOQ is always constant data according to the design factors of a particular project. On the contrary, statistical models can provide cost quicker and more reliable than traditional ones if the collected cost data are sufficient enough to analyze the trends of the variables. The estimation system considers non-deterministic methods which referred to as the 'Monte Carlo simulation. The method interprets cost data to generate a probabilistic distribution for total costs from the deficient elemental experience cost distribution.

This study conducts an analysis on the relative significance and urgency of competence factors for jobs in the field of Social Welfare through a demand analysis on the vocational training of the K Human Resource Development Institute regarding the National Competency Standards (NCS) in the field of Social Welfare, which was developed in the year 2014. The aim is to derive competence factors with high demands in education and high necessity of curriculum development based on the analysis. The data of 1,227 persons: 583 public officials and 644 private employees, was analyzed by using SPSS 18.0 and Microsoft Excel 2013. Results of the demand assessment on vocational training are as follows: for public officials, 4 competences in social development jobs (social area analysis, needs assessment, community resource building, community network, social assessment, community organizing, and welfare planning), 2 competences in public welfare jobs (management of unusual complaints in welfare and civil cooperation in resource development), and 2 competences in social welfare administration jobs (financial management in social welfare organizations and welfare planning) had high urgency in competence development. Implications were suggested based on the results.

Business consignment using personal information is increasing for the operating profit and work efficiency of Internet companies. If the personal information leakage accident occurs at the consignee, the consigner who provided personal information will be damaged greatly. The purpose of this study is to analyze the business attributes of consignee using consigned personal information and present a model that can be used to select companies with high risk of personal information leakage by considering the importance of the involved personal information. For this, personal information consignment relations, consignment services, and personal information items used were analyzed. Social network analysis and cluster analysis were applied to select companies with high network centrality that are advisable to obtain information security certification. The results of this study could be used to establish information protection strategies for private or public enterprises that manage companies using personal information.

For the long-term preservation of document-type electronic records, the National Archives of Korea has chosen PDF/A-1 as the preservation format named as the document file format, and established it as a public standard. The only option of selecting PDF/A-1 restricts the use of various electronic file formats that can or must be applied to actual works as IT advances and tasks change. Moreover, it is difficult to apply PDF/A-1 to other types of electronic records (administrative information datasets, audiovisual records, web records, etc.). Therefore, it is necessary to diversify the preservation formats of electronic records. We suggest a framework for selecting various preservation formats. Furthermore, we propose common criteria and evaluation methods frequently applied to all electronic records when selecting a preservation format, and introduce a methodology for deriving intrinsic criteria applied to each type of electronic records.

Geographic data have widely been applied in different areas including landuse, city planning and management, environment, disaster management and even daily use of citizens. Since geographic data have been built individually using different methods, many problems such as data inconsistency, duplicated investment, and confusion in decision making have arisen. Thus, the necessity of national framework database that can be shared by different areas has increased. As a result, eight fields of the framework database were defined by NGIS Law and 19 detailed items were selected. This study used the AHP (Analytical Hierarchy Process) and the decision tree to evaluate the relative importance of the items (eg. roads, railroads, coastline, surveying control points, and etc.) and presented the groups classified according to the priorities of the items. The result of this study is believed to contribute to effective budget planning for building national framework database.
