From a genomic library of Lactobacillus reuteri ATCC 55739, one clone, NE347, carrying a pyrH gene encoding UMP kinase, was identified. pNE347 carried a 1.88 kb EcoRI fragment and the pyrH was located in the middle of the insert. pyrH ORF was 723 bp in size and capable of encoding UMP kinase composed of 240 amino acid residues. tsf encoding an elongation factor-Ts and frr encoding a ribosomal recycling factor were present upstream and downstream of pyrH, respectively. When introduced into E. coli KUR1244, a pyrH-negative strain, pNE347 restored the ability to grow at $42^{\circ}C$, indicating that pyrH from L. reuteri synthesized functional UMP kinase in E. coli. Northern blot experiment showed that pyrH and frr were cotranscribed as a 1.4 kb single transcript. pyrH was overexpressed in E. coli by using a pET26b(+) vector, and a major 25 kDa protein band appeared on SDS-polyacrylamide gel.

This study investigated high school students' perception of English extensive reading (ER) after introducing ER to general high school students in a metropolitan area. In addition, as the free semester system was expanded in high schools as well as middle schools, we developed a class model for English extensive reading. 91.4 percent of the students who participated in the study said that they wanted to try using the English extensive reading method. Also 35 high school students who experienced English extensive reading chose the 'Five Finger rule' and 'Graded Readers' Series' as the most helpful factors in their extensive reading experiences. In interviews with English teachers, teachers expressed their demand for the development of a model of English extensive reading suitable for free semesters in general high schools. This study proposes an English extensive reading class model utilizing library resources that can be used in the free semester system as well as a performance assessment-oriented English extensive reading class model.

The hepatitis B virus (HBV) envelope contains small (S), middle (M), and large (L) proteins. PreS1 of the L protein contains a receptor-binding motif crucial for HBV infection. This motif is highly conserved among 10 HBV genotypes (A-J), making it a potential target for the prevention of HBV infection. In this study, we successfully generated a neutralizing human monoclonal antibody (mAb), 1A8 (IgG1), that recognizes the receptor-binding motif of preS1 using a phage-displayed human synthetic Fab library. Analysis of the antigen-binding activity of 1A8 for different genotypes indicated that it can specifically bind to the preS1 of major HBV genotypes (A-D). Based on Bio-Layer interferometry, the affinity ($K_D$) of 1A8 for the preS1 of genotype C was 3.55 nM. 1A8 immunoprecipitated the hepatitis B virions of genotypes C and D. In an in vitro neutralization assay using HepG2 cells overexpressing the cellular receptor sodium taurocholate cotransporting polypeptide, 1A8 effectively neutralized HBV infection with genotype D. Taken together, the results suggest that 1A8 may neutralize the four HBV genotypes. Considering that genotypes A-D are most prevalent, 1A8 may be a neutralizing human mAb with promising potential in the prevention and treatment of HBV infection.

The study aims to explore 'reading promotion projects' led by the Korean Education Office and to ponder meaning of the projects, and then to propose the future directions for the projects. To achieve the purpose, the study selected to analyze a reading promotion project called as "Ulsan Students' Reading Day~" by Ulsan MetropolitanCity Office of Education as a case and sample for the study. The study was designed to use two research methods and phases to explore the project in detail: documentary research and survey method. First, the study collected and analyzed the literatures and contents related to the projects but focused on examining progresses of the project such as situations from the introduction stage to the settlement stage. Second, the study conducted survey to collect data from teachers and students who have experienced the project in elementary, middle and high schools. The detailed contents of questionnaires contain current states of the project in each school, assessment of the project, and requirements for the project. The study found that the project resulted in positive influence to students' reading skills and education. In spite of these positive results, it is necessary to develop altenatives to solve some limts in the current states of the project. Reading promotion projects, in long run, need to have profeissional staffs with responsbility for managing the projects, to improve environments for reading promotion, and to encourage students' voluntary participation to the projects.

The purpose of this study is to compare the reading effects of face-to-face reading discussion with those of web-based leading discussion. For doing this, 1 made experimental processes: firstly, to select two discussion methods(face-to-face and web-based) on the reading discussion, secondly to apply each of those methods to experimental groups(2 classrooms, 72 middle school students). The results were that there were no differences from both discussion methods in the understanding the book, in the performance degree on discussion process among higher level groups, but the web-based reading discussion model had an impact on the attitude degree of the reading discussion, the preference degree of reading, the attendance degree of reading discussion, and especially, in the lower level groups, the web-based reading discussion method was better for the attendance degree of leading discussion, the attitude of reading discussion than the face-to-face reading discussion.

Today's society demands that Individuals need to acquire skills to select information they need, read critically that have been gathered and use them for their advantage. The ability to actively respond to information can be cultivated through reading which facilitates creative, critical thinking, and self-initiated learning. This research presents results from a study in which subject-centered approach to reading guidance was applied to elicit positive changes in reading attitudes and to contribute to the elevation of self-concept among adolescents. Using survey questionnaire, we compared the changes in reading attitude before and after treatment. The results indicate that subject-centered reading instruction brought positive changes in reading attitude among middle school students, contributed positively to the formation of self-concept and the improved student initiated learning.

In order to create a safe and comfortable educational environment and improve the quality of education, the 'Act on the Safety and Maintenance of Educational Facilities' was enacted in 2021. Accordingly, 'Educational Facility Safety Certification Operation Regulations' was established. Safety certification targets are classified into 'kindergarten', 'elementary/middle/high school and special schools', and 'university and other educational facilities'. Other educational facilities include libraries and student training facilities. However, student training facilities and libraries are different from schools as facilities for special activities such as training and reading. Therefore, the unique characteristics of the facility must be reflected in the 'Educational Facility Safety Certification Operation Regulations'. This study analyzed how the 'Educational Facility Safety Certification Operation Regulation' reflects the special characteristics of student training facilities and libraries that are 'other educational facilities'. The previous certification system and guidelines were compared and analyzed, and the on-site survey method was used. Finally, it was confirmed that each of the library and the student training facility needed 9 detailed criteria reviews.
