This study aims to examine how the specialty of librarians links between users' library experience and their resulting perception of the library in public libraries. After reviewing theoretical background studies, a questionnaire survey was conducted at six public libraries in Seoul and Gyeonggi Province. The analysis of the survey results showed that the perception of librarians' specialty had a mediation effect on the relationship between cultural, educational activity and library perception. However, information activity was not linked by the perception of librarians' specialty and only directly influenced on the library perception. Accordingly, the result raised a question of a discrepancy between the areas where the users gain the value of the library and where the librarians' specialty is perceived and some implications were suggested. This research is meaningful in integrating the users' library experience, librarians' specialty, and the library performance by external point of view on the specialty, traditionally regarded as an internal characteristic of the librarianship.

Residential Environment Improvement Project (REIP) which has started in 1989 and continued with 3rd government-supporting project in 2013 has lots of policy changes and related studies. However, the related researches have focused on residents resettlement into the project site, this paper is more interested in the residents stability than residents resettlement. So, this paper analyzes the changes of residents stability on the site of REIPs (with 3 groups of dwellers, removers and newcomers). We survey about understanding of those projects, each interior physical housing characters, housing cost, outside settlement characters. On the base of case analysis, we can conclude as follows: firstly, the residents are more young, higher educated, and higher income but not alter to household, barrier, occupation. Secondly, REIPs have some positive influences on physical conditions of housing and outside characters but negative impacts on housing cost. In case of newcomers, there are no changes of housing size and room numbers but higher housing cost, better outside settlement conditions.

The pandemic caused by the COVID-19 virus, which has lasted for the past three years, has changed society and the way people live in many ways. These changes also affect cyberspace, so the pre-pandemic information security model and standards have limitations when applied to the current situation. In this paper, a new method to improve the information security model of public institutions was proposed in consideration of various situations in the new normal era. In other words, through the proposed information security model, the possibility of external intrusion is blocked in advance through the policy and technical supplementation of remote work, which is a weakness of the existing information security operation of public institutions. Also, how to prevent abnormal authentication attempts by building a secure VPN environment, how to prevent social engineering cyber attacks targeting fear and uncertainty caused by COVID-19, and how to use a smooth network and create a remote work environment. For this purpose, methods for securing service availability were additionally presented.

This study determined the communicative characteristics of public libraries through locality, communality, interactivity, and organism and sought to measure the validity of their components to define the role of libraries based on the analysis. According to the analysis results, there are four communicative characteristics of public libraries: locality, communality, interactivity, and organism. This study defined the role of public libraries according to communicative characteristics. First, libraries should encourage the formation of a healthy society by providing a space for diverse community activities, contributing to the building and strengthening of their local communities, and offering the necessary information to do so. Second, libraries should contribute to the formation of local cultural communities and strengthen interpersonal relations among community members to reinforce a sense of community, while also supporting the heightening of social adaptability to foster a sense of belonging and community activity participation among members. Third, libraries act as a space for sharing ideas between generations, provide a space to carry out leisure activities, and enable the cultural prosperity of local communities. Lastly, as a representative space of local communities, libraries raise the value of the residential environment and contribute to their communities and members.

This paper illustrates key features of an enterprise employment simulation which integrates a system dynamic feedback model with a cost-effectiveness optimisation capability utilising genetic algorithms. Its core is a 3-dimensional array structure tracking staff numbers by rank, by time-in-rank, by years-of-service. The resultant model, which could readily be adapted to non-Defence use, can identify, given user specification of any mix of employment rules, the likely patterns of employment behaviour including: resultant time-in-rank and years-of-service profiles; ability of a Unit to fill all positions to target strength; ability to fill promotional positions within normal rules for substantive promotion; need to fill promotional positions using rules for temporary promotion or transfer from outside; necessary recruitment pattern to sustain target strength.

It is essential for any public institution to establish a systematical scheme and a management system to maintain the contents and securities of its ever-expanding web-site with efficiency. The general users want a reliable system and a simple and stress-free web environment and expect the public institutions to maintain the accuracy and conformity of information they provide to the public. In this study, I examined a web-site owned by a certain governmental research institute for the current maintenance status and problems to seek an effective and easy-to-use scheme for both users and web managers. Based on what I learned from my study, I moved on to design a web integration system and tested it on the above mentioned web-site for analysis.

In the field of public informatization maintenance business, the attacks of external illegal users such as unauthorized leakage, destruction, and alteration due to intentional or inadequate management of personal information are increasing. In order to prevent such security incidents in advance, it is necessary to develop and quantitatively manage SLA indicators. This study presents the privacy SLA indicators and suggests specific methods such as information collection method and timing of the privacy SLA indicators. In order to confirm the validity and reliability of the proposed SLA indicators, an online survey was conducted with a group of experts. As a result, it was evaluated that compliance rate of personal information destruction and compliance rate of personal information protection system would be effective when applied to new and revised SLA indicators in terms of importance and validity. In the future, using SLA indicators for personal information protection as a standard for public information maintenance will contribute to improving SW quality and securing safety.

정보 통신 기술의 발달이 인간 생활에 많은 편리함을 가져다 주었지만 개인의 정보 유출이나 소음 공해 등의 여러 가지 문제점도 야기 시켰다. 특히 휴대 전화 통화시 사용자의 개인적인 정보들이 공공 장소에서 그대로 노출이 되고, 또 그러한 통화로 인해서 타인에게 소음 피해를 주기도 한다. 이러한 병폐를 막기 위해서 휴대 전화 사용자는 최대한 작은 소리로 통화를 하되, 상대방에게 의도하고자 하는 바를 확실히 전달하여야 한다. 그러기 위해서는 휴대 전화에 근접 통화가 가능해야 하며, 일정한 방향의 방향성을 가져서 주위의 잡음에 대해 독립적으로 작동하도록 해야한다. 본 논문에서는 이러한 기능을 향상시키기 위하여 음향학적 이론을 바탕으로 휴대전화에 사용되어지는 마이크로폰을 새로 설계, 제작하고 그 성능을 시험하였다. 아주 작은 소리로 근접 통화를 할 때 발생하는 팝핑(popping) 현상이 최소한이 되도록 미세관 배열을 적용하였으며, 외부 소음 영향을 줄이기 위하여 방향성을 증폭시키고자 음원의 위치에 초점을 맞추는 기술을 적용하였다. 방향성 증폭은 4개의 마이크로폰 사용과 근거리 음원의 방향성 증가를 위한 신호 처리기술을 적용하였다. 이 기술의 적용 효과를 실험을 통하여 검증할 수 있었다.

This work aims to firstly know what does the inside and outside participants perceive the system itself and its execution in the evaluation of the research institutes in science and technology sector which has been introduced in 1999, and to secondly discuss how can diverse perceptions among participants be integrated in the institutional and operational aspects. This has been conducted mainly by in-depth interviews with 99 staffs from 10 research institutes under the Korea Research Council for Public Technology as well as with 10 members of evaluation committee for research institutes. According to the in-depth interviews, the both inside and outside participants perceive that the evaluation of research institutes can be necessary and useful for the management of the institute itself and R&D programs in view of the strategic reasons as well as practical one. Despite of the affirmative perceptions to the evaluation of research institute, based on the common or individual experiences, they have also suggested that there will be lots of improvements in the individual components of evaluation system and its current status of execution.
