The purpose of this study is to identify how teacher librarians perceive the importance of each job and the expected job of other teachers and students, and to obtain basic information on their job recognition and to derive their jobs to be improved. To this end, after modifying the 25 jobs selected by Lim Jeong-hoon et al.(2021), 210 librarian teachers were measured for their own importance by job, the expected importance of other teachers and students, and the level of evaluation of their own performance ability. As a result of the analysis, teacher librarians recognized 'reading education and literacy education' as the most important, but recognized 'library event' as the most important task expected of other teachers and students, and recognized that 'library usage guidance' was the most outstanding. In addition, there were nine jobs that needed to be improved.

Along with the development of coasts, islands and mountains, the demand of long-span bridges increases which, in turn, brings forth the construction of cable-supported bridges like suspension and cable-stayed bridges. There are various types of statically indeterminate structures widely applied that supported the main girder with stay cables, main cables, hanger cables with aesthetic structural appearance. As to the cable-supported bridges, the health monitoring of a bridge can be identified by measuring tension force on cable repeatedly. The tension force on cable is measured either by direct measurement of stress of cable using load cell or hydraulic jack, or by vibration method estimating tension force using cable shape and measured dynamic characteristics. In this study, a method to estimate dynamic characteristics of hanger cables by using a digital image processing is suggested. Digital images are acquired by a portable digital camcorder, which is the sensor to remotely measure dynamic responses considering convenient and economical aspects for use. A digital image correlation(DIC) technique is applied for digital image processing, and an image transform function(ITF) to correct the geometric distortion induced from the deformed images is used to estimate subpixel. And, the correction of motion of vision-based measurement system using a fixed object in an image without installing additional sensor can be enhanced the resolution of dynamic responses and modal frequencies of hanger cables.

This study was undertaken to identify effects of the peer group reading program (PGRP) on the tenacity, self-resilience, and adaptation to university life of new entrants to the university. This was a non-equivalence control group quasi-experimental research study design. The subjects examined were entrants at the S University. The experimental group was provided the PGRP, and the control group was provided a general program for 13 weeks. The PGRP consisted of three or four students per group. Each group read one book for one week. Subsequently, all students gathered and presented their reading reports and discussed their comments, once a week. Data were analyzed using Chi-square test and t-test to compare the differences between both groups. A total of 73 subjects were included in the study: 34 in the experimental group and 39 in the control group. There were no significant differences in the general characteristics between the groups. Furthermore, no significant differences were observed between both groups before the intervention; however, the experimental group showed improved tenacity (p<0.01) and self-resilience (p=0.020) after the intervention, which were significantly different between both groups. Our results indicate the requirement to develop and apply various reading programs for improving the personality, self-resilience, and college life adaptability of university entrants.

Estimates of project costs in the early stages of a construction project have a significant impact on the operator's decision-making in important matters, such as the site's decision or the construction period. However, it is difficult to carry out the initial stage with confidence because information such as design books and specifications is not available. In previous studies, case-based reasoning was used to predict initial construction costs, and genetic algorithms were used to calculate the weight of the inquiry phase among them. However, some say that it is difficult to perform better than the current year because existing genetic algorithms are calculated in random numbers. To overcome these limitations, correlation numbers using correlation analysis rather than random numbers are reflected in the genetic algorithm by method of local search, and weights are calculated using a hybrid genetic algorithm that combines local search and genetic algorithms. A case-based reasoning model was developed using the weights calculated and validated with the data. As a result, it was found that the hybrid GA-CBR applied with local search performed better than the existing GA-CBR.

With the rapid growth and development of information technology and the Internet, the amount of information published in electronic formats such as video, audio, digitalized text, etc. and the number of users accessing information online to satisfy their information needs are growing at a tremendous rate. This study analyzes standardized components to construct ERMS and proposes a model of ERMS based on the result of the analysis. The main functions of ERMS in university libraries are: 1) ERMS can manage and control access information to various electronic resources, metadata, holdings, user resources. Also, ERMS can be compatible with an existing library system such as IR(Information Retrieval) system, linking system, or proxy system. 2) ERMS should completely be compatible with acquisition and cataloging systems for effective management and control of integrated information organization and library budget. 3) ERMS should systematically and effectively manage license information on electronic resources. 4) ERMS should provide ideal and effective environment for use and access control of electronic resources in a library and integrated tool to manage and control all of electronic resources. Additionally, this study points out the need to organize committee groups to establish standardized rules and collaborative management of electronic resources among university libraries like DLF ERMI and redesign organizations in a library and a librarian's job description.

The purpose of this study is to present the directivity of outcome management through the analysis of public library operations in Seoul. For this purpose, author evaluated the public library policies by linking the 「Metropolitan Comprehensive Library Advancement Plan 2018~2022」 and 「The Third Comprehensive Library Advancement Plan: 2020 implementation plan」 and compiled to draw up the issue of policy development on the awareness of public library services by Seoul citizens. Nest, author analyzed and compared the core infrastructure, collection services, programs and activities of 173 public libraries in 25 local governments. Based on these results, author suggested the directivity of outcome management as follow. All public libraries in Seoul must emphasize the development scope and management methods of the performance indicators. For outcome management, this study emphasized building a strategy planning with the development procedures of performance indicators, categorizing outcome management indicators, developing user-centered indicators, and improving qualitative indicators. As there is a possibility that the quality of services expressed in the output may deteriorate due to the failure of the physical input indicators, it is necessary to strengthen the input and encourage the resolution of the service gap by establishing a performance management system to logically explain the relevance or causal relationship between these indicators.

Recently government is set to expand its policy to promote technical proposal tendering in a dimension of technical competitiveness reinforcement. Because a variety of complicated techniques are applied in technical proposal tendering and variables could be occurred in terms of cost, schedule, constructability and others when techniques are reflected on design document collaboration management among participants is considered insignificantly. So the research would determine primary management factors and presents management direction for collaboration among participants. First action for this is categorization of hindrance factors to collaboration into five factors as 'Poor work processing', 'Communication cap among participants', 'Lack of understanding about technical proposal tendering', 'Difficulty of decision making' and 'Insufficiency in managing the work data'. Second correlation analysis is conducted between the categorized factors and participants according to tasks in technical proposal tendering to figure out the correlation degree of variables. If there is a strong correlation between variables, hindrance factor in that case regarded primary management factor to collaboration and finally management direction is presented at each task.

Cost Estimating allows each entity in a construction project to plan, distribute, and control its required construction cost for the project. However, existing 2D design based estimating has problems, such as inaccuracy and inefficiency caused by missing, duplicated, or erroneous calculations. In this situation, current estimations for school facilities have more difficulties in forecasting construction costs due to an inadequate work breakdown structure for BOQ (Bill of Quantity) and insufficient guidelines for Basis of Estimate. In this study, therefore, an effort was made to increase the efficiency of estimating for school facilities by applying a 3D modeling based BIM tool to quantity and cost estimates. In addition, this study suggested a reasonable work breakdown structure for BOQ that was appropriate when 3D modeling was applied, and verified it through a case study. The authors tried to provide a BIM-based estimating method for school facilities to obtain greater accuracy and efficiency by having more information in an earlier stage.
