This study examines the teachers' perception of the school library's role and the teacher-librarian expertise that enables collaborative reading education in elementary schools. Furthermore, it develops strategies that the school library and teacher-librarians should undertake for collaborative reading education. The questionnaire was developed to survey 176 teachers in 9 elementary schools in Gyeonggi-do. As a result, the teacher's perception of the school library's role and event role perception would positively impact the expected effects of collaborative reading education intention. This study is meaningful in that suggestions are offered for collaborative reading education and where teacher-librarian expertise is placed.

This study analyzed the respective teaching and learning-related services offered by the Centers for Teaching and Learning and the academic libraries to find the proper roles of libraries regarding this type of service. We interviewed librarians to collect the data. The content analysis of the qualitative interview data enabled us to identify the librarians' perceptions of teaching and learning support, service provision method, strengthening relationships with other academic units, recognition of libraries' roles within the universities, and generating more investment for the libraries. Finally, the analysis led to six suggestions for libraries' teaching and learning support functions, such as advertising the availability of specific academic discipline or unit-oriented library services, strengthening librarian's capabilities as educators, bolstering digital information literacy of the faculty members and students, injecting libraries' views into the development and maintaining fundamental knowledge-related programs, emphasizing the notion of human-centered libraries, and finding new ways to utilize library space.

The purpose of this study is to analyze the factors that hinder the role recognition and role performance of teacher librarians and suggest some improvement methods. For this purpose, a questionnaire was conducted among 41 persons who participated in the first-level qualification training for teachers librarians at K University Secondary Teacher Training Institute in 2019.The results showed that there was a difference between the expected role and the execution role of the teacher librarians. In other words, teacher librarians recognize that they should teach information literacy as instructors and operate library-based instruction and cooperative classes as teaching partners. However, the most frequently played roles are reading education and library use education. They recognizes the cause as institutional limitations, such as the absence of a national level curriculum and the ambiguity of the role of specialists in school libraries. And it is perceived as a real problem such as the lack of partnership and recognition of their peers. Among the variables of teacher librarians, the higher their educational level, the more they perceived their peers as teachers. Based on this, some suggestions for strengthening the role of the teacher librarians' instructor and teaching partner were proposed in terms of including cross-curricular subjects of information literacy education, analyzing jobs and establishing scholarship system for school libraries.

Recently, based on the human speech recognition (HSR) model of Fletcher, the multi-band speech recognition has been intensively studied by many researchers. As a new automatic speech recognition (ASR) technique, the multi-band speech recognition splits the frequency domain into several sub-bands and recognizes each sub-band independently. The likelihood scores of sub-bands are weighted according to reliabilities of sub-bands and re-combined to make a final decision. This approach is known to be robust under noisy environments. When the noise is stationary a sub-band SNR can be estimated using the noise information in non-speech interval. However, if the noise is non-stationary it is not feasible to obtain the sub-band SNR. This paper proposes the inverse sub-band distance (ISD) weighting, where a distance of each sub-band is calculated by a stochastic matching of input feature vectors and hidden Markov models. The inverse distance is used as a sub-band weight. Experiments on 1500∼1800㎐ band-limited white noise and classical guitar sound revealed that the proposed method could represent the sub-band reliability effectively and improve the performance under both stationary and non-stationary band-limited noise environments.

본 연구의 목적은 사서와 이용자가 지닌 도서관 규범을 사서의 역할 규범을 중심으로 비교 분석하는 것이다. 분석 결과, 사서는 이용자 및 정보에 대한 전문성을 바탕으로 정보서비스를 제공해야 한다는 역할 규범을 지니고 있었다. 그러나 이는 실제로 지켜지기보다는 규정적인 차원으로 존재하고 있었다. 반면 이용자는 사서의 역할 규범에 대한 인식이 약했지만, 경험을 통해 '사서는 자료에 대한 전문성을 바탕으로 개인에게 정보서비스를 제공해야 한다'는 기술적 차원의 역할 규범을 지니고 있었다.

The purpose of this study was to analyze children's perspectives on the role of male childcare teachers and children' s gender role concepts. According to the results, when it comes to how the children perceive the roles of the male childcare teacher, the children mostly saw the male childcare teacher as a person who teaches and in another case, they regarded him as someone who takes care of their daily life and who is willing to play games with them. On the other hand, the male childcare teacher's organizing of an environment, supporting tasks and working on a computer were perceived less by the children. In terms of the gender role concepts, the study confirmed that depending on the role performance of the male childcare teacher, the children in the male childcare teacher's class had better understanding than those children in the female childcare teacher's class. In order to secure the children's right to participate specified in the convention of the rights of the child, the study applied not only the interviews with the children but also their drawings to the analysis, and that was what led the study to an in-depth discussion on the perception of the children.

Developing context awareness service In these day, It demands high security in context awareness service. So GEO-RBAC that provide user assignment of spatial role, assignment of permission, role schema, role instance and spatial role hierarchy to context awareness service is access control model to perfect in context awareness service. But GEO-RBAC is not considering temporal constraints that have to need context awareness environment. Consequently this paper improves the flexibleness of GEO-RBAC to consider time and period constraints notion and the time of GTRBAC that presents effective access control model. also we propose GEO-RBAC to consider temporal constraints for effective access control despite a various case.

This study aims at providing the basic data to help establish the right identity of dental hygienist and develop the work of dental hygienists, and thereby investigating the effect of patients' perception of dental hygienist on their social demand of dental hygienist, by conducting a survey of 300 patients visiting dentists around Busan-Gyeongnam region from April 7, 2012 to April 25, 2012. The collected data is statistically analyzed by SPSS (Statistical Packages for Social Science 14.0. SPSS Inc., Chicago, IL, USA). First, I analyzed the frequency by suggesting the demographic and descriptive characteristics of data, and conducted t-test and One-Way ANOVA at 5% of significance level to figure out the degree of perception and social demand of dental hygienists depending on customers' reason for visiting dentists, and also conducted regression analysis to find the effect of the perception of dental hygienist on patient's social demand of dental hygienist. The result suggests that as the perception of the dental hygienists' role, the social demand for dental hygienists' image increases, but as perception of dental hygienists' image increases, the social demand of dental hygienists' image decreases. Therefore, it suggests that as the knowledge about dental hygienists increases, patients demand their service more, while the perception of their image lowers the social demand for their image. It turns out that as the knowledge of dental hygienists increase, the social demand for the knowledge also increases.
