The study examined the behavior of infant's caregivers using public libraries, measured the level of awareness of infant and toddler services in the library to determine the factors affecting their revisit or recommendation of use to others, and examined the impact of such recognition on the use behavior, revisit and willingness to recommend others. The study surveyed 146 caregivers of infants who use four public libraries in Gwangju Metropolitan City on demographic characteristics, library use behavior, level of awareness of library services, library revisit and recommendation to others. Analysis of this survey shows that the factors that influence the caregivers' revisit of the library or their desire to recommend to others through their caregivers' use of the library are the factors that influence the expansion of information data, the stability of space facilities, the accessibility of space facilities, and the ease of participation in programs among the various service factors provided by the library rather than the personal factors of infants and toddlers' caregivers.

This study aims to understand the characteristics of civil petitions and complaints within public libraries and to identify factors to the civil petitions. We develop a survey questionnaire for the goals based on the previous related studies and a pilot study with several open-ended interviews with public library users. Then we collect data using the questionnaire from 154 survey participants (public library users). The collected data are statistically analyzed by using factor analysis, canonical correlation analysis, and multiple linear regression analysis. The results show that there are two identified dependent factors, such as petition and complaint, and six independent factors, including librarian specialty, service convenience, and communication between librarians and users. Through a series of statistical analysis for identifying specific relationships between individual dependent factors and predictors, we discuss the characteristics of the library civil petitions and complaints, and the importance of a structural/relation-based approach to the library civil petition as a complimentary for the functional approach. Based on the results and discussions, we suggest several future research directions, including research on the relationship between the library civil petitions and library performances.

This study examined the demographic characteristics of the elderly who use public libraries in Daejoen Metropolitan City. Their tendencies in using the library level of satisfaction about the library and how the library affects their life were also evaluated. The survey revealed there were more man than woman users. And most users being relatively healthy sixties, highly educated and belonging to the middle class were indicated. They have been using the library frequently and regularly for a long time and were highly satisfied with the services from librarians and other staffs. Also the Public library services had a positive effect on the quality of the life of the elderly. As a result, an effective program for servicing potential visitors who are in poor health, over 70 years old, having lower level of education, living in below standard conditions, and living far from the library were suggested. Elderly women also will be the potential visitors.

In this study, we wanted to find out about the perceptions and the requirements of the academic information service users about the Library 2.0. This study used the survey research method, which utilized the web-based survey using the academic information service users as the target population. Specifically, we studied whether and how the users recognized and experienced the Web 2.0 technologies and its related services with respect to Library 2.0. In addition, we gathered the requirements for the Library 2.0 concept applied information services. The analysis results showed that the users were in need of obtaining the most up-to-date information and also using the professional information services such as the experts generated information contents and the Google Scholar type document reference information services instead of the Library 2.0 services based on the Web 2.0 technologies.

This Paper assesses the relative efficiency of public library services by examining the relationship between library inputs and library outputs in library systems. Using Data Envelopment Analysis, this study derives efficiency scores in the provision of library services for 21 public libraries in Seoul. The data are survey observations for 2002. We employ total holdings, total serials, and total acquisitions as inputs, and total circulations and reader visits as outputs. The result shows that the subject libraries operate at just $71\%$ efficiency, i.e., inputs could be reduced by one-three without sacrificing output if all libraries were as efficient as the benchmark 4 identified by DEA. Too many total collections are the main source of inefficiency.

The purpose of this study is to investigate the model of cluster analysis techniques for grouping public libraries and analyze their characteristics. Statistical data of public libraries of the National Library Statistics System were used, and three models of cluster analysis were applied. As a result of the study, cluster analysis was conducted based on the size of public libraries, and it was largely divided into two clusters. The size of the cluster was largely skewed to one side. For grouping based on size, the ward method of hierarchical cluster analysis and the k-means cluster analysis model were suitable. Three suggestions were presented as implications of the grouping method of public libraries. First, it is necessary to collect library service-related data in addition to statistical data. Second, an analysis model suitable for the data set to be analyzed must be applied. Third, it is necessary to study the possibility of using cluster analysis techniques in various fields other than library grouping.

Many university libraries, facing financial difficulties, have been forced to operate on a tighter budget. Such trend has created the need for an objective standard that will prioritize current library services. This study derives service quality factor via open coding from internet postings posted in the last five years on the Korean National Open University's library website, and also calculates the customer satisfaction quotient and dissatisfaction quotient using the Kano Model and Timko's Customer Satisfaction Coefficient. The result draws 25 service quality factors across 3 categories consisting of: (i) 8 attractive qualities, (ii) 15 one-dimensional qualities and (iii) 2 reverse qualities. The study, through the calculation of Timko's Customer Satisfaction Coefficient per service quality, proposes an intensive service that can prioritize the efficient use of library budget.

This study analyzed the gap between users' perception and staff expectations on users' perceptions about dimensions of library service quality(library staff, service supports. materials and resources, and facilities and equipments), service value, user satisfaction, royalty. using newly developed model. Six hundred-fourteen users and one hundred staff members or the National Libra of Korea were participated in the survey using questionnaires. Users evaluated service quality lower but evaluated service value, satisfaction. and loyalty higher In terms of showing complaining behaviors, users were less than staffs expected. Model analysis for users and staff3 showed that service value and general satisfaction influenced on complaining behavior and loyalty. For users. only the dimension of library staff influenced significantly on the service value, satisfaction, complaining behavior, and loyalty. None of the other dimensions of the service qualify showed significant relationship to them in the case of staff expectation.

Aphis gossypii Glover is an important insect pest that functions as a viral vector and mediates approximately 45 different viral diseases. As part of a strategy for control of A. gossypii, we investigated the functions of genes using RNAi. To this end, a cDNA library was constructed for various genes and for selecting appropriate targets for RNAi mediated silencing. The cDNA library was constructed using the Gateway cloning system with site-specific recombination of bacteriophage ${\lambda}$. It was used to carry out single step cloning of A. gossypii cDNAs. As a result, a cDNA library with a titer of $8.4{\times}10^6$ was constructed. Since the sequences in this library carry att sites, they can be cloned into various binary vectors. This library will be of value for various studies. For later screening of selected genes, it is planned to clone the library into virus-induced gene silencing (VIGS) vectors, which makes it possible to analyze gene function and allow subsequent transfection of plants. Such transfection experiments will allow testing of RNAi-induced insecticidal activity or repellent activity to A. gossypii, and result in the identification of target genes. It is also expected that the constructed cDNA library will be useful for analysis of gene functions in A. gossypii.

Because the library cannot be run independently and used by many applications, it is important to detect vulnerabilities in the library. Fuzzing, which is a dynamic analysis, is used to discover vulnerabilities for the library. Although this fuzzing technique shows excellent results in terms of code coverage and unique crash counts, it is difficult to apply its effects to library fuzzing. In particular, a fuzzing executable and a seed corpus are needed that execute the library code by calling a specific function sequence and passing the input of the fuzzer to reproduce the various states of the library. Generating the fuzzing environment such as fuzzing executable and a seed corpus is challenging because it requires both understanding about the library and fuzzing knowledge. We propose a novel method to improve the ease of library fuzzing and enhance code coverage and crash detection performance by using a test framework. The systems's performance in this paper was applied to nine open-source libraries and was verified through comparison with previous studies.
