This study was conducted to identify the operation status of Dobong-gu public libraries in order to establish a mid- to long-term development plan for Dobong-gu libraries, and to analyze local residents' perceptions of libraries by factors through user surveys to suggest specific development plans for Dobong-gu libraries. Overall, the satisfaction level of Dobong-gu residents with library services was found to be high, and all libraries were analyzed to be providing high-quality services. From this, the following operational strategies for the mid- to long-term development plan of Dobong-gu public libraries can be derived. First, libraries need to continue to collect and provide books that meet the quantitative and qualitative levels to satisfy the needs of the community and users. Electronic and online materials, including e-books and audiobooks, as well as subject-specific materials should be expanded to provide relevant programs. Second, although Dobong-gu is an aging city, a wide range of age live there, so there is a need to promote communication and understanding between generations and promote integration of the community through a generational empathy program. Third, it is necessary to remodel and improve the space of aging libraries by organizing library facilities and environments into open spaces and creating makerspaces and multicultural spaces for direct experience and practice, reflecting the latest trends in library space organization.

This study analyzed the general user behaviors and the perceptions on service quality, satisfaction, loyalty of the users of the special winter vacation programs at the public libraries in Daegu Metropolitan City. Among the 444 collected questionnaires from the participants in the programs at 8 public libraries in the City, a total of 300 were analyzed for the study. As results, many participants have visited the libraries with their family members, and have applied the programs through the helps from their parents. They rated higher the service quality, the satisfaction, and the loyalty than other child users of the children's services as well as the adult participants of the cultural programs and of the public libraries. In the analysis of the structural equation model (SEM) on the service quality, customer satisfaction and loyalty, all of the service quality factors of special winter vacation programs, namely program contents and instructors, staff supports and services, and facilities and equipments, have significant effects on the user satisfaction. Staff supports and services factor of the service quality has significant direct effects on loyalty along with the overall satisfaction, but program contents and instructors factor and facilities and equipments factor have no significant direct effects on loyalty.

Due to the growth of people's use of the Internet as well as interests in health, people's needs of health information have rapidly increased in public libraries. Nevertheless, there are few studies in Korea about users' needs for health information and services that public libraries can offer to support these user groups. In the current study, a comprehensive literature review was conducted in order to understand the role of public libraries and librarians in serving users with health information and to identify the types of consumer health information(CHI) services available to users in public libraries. As for the CHI services that public libraries can offer for users, the current study emphasizes and discusses the directions and guidelines for improving the following six approaches: 1) CHI collection and information resource building, 2) CHI reference services, 3) CHI user education and training program development, 4) CHI services for minority/disability/cultural diversity groups of users, 5) CHI outreach program development, and 6) CHI network development with medical libraries, academic libraries, hospital, and medical institutions and associations. Although most of the discussion in the current study centers on cases and services provided in the United States or other countries, findings would be used to inform the importance of CHI services in public libraries, and to design and develop CHI services in Korea.

Even though three isotypes of thioredoxins (-f, -m and -h types) have been identified in a variety of plant cells, there are only a few reports on thioredoxin-h that were recently identified. In this study, a cDNA encoding a h-type of thioredoxin was isolated from a cDNA library of Chinese cabbage, and named here CTrx-h. An open reading frame of the gene contained a polypeptide of 133 amino acids with a conserved active center, WCGPC, which appeared in all of the thioredoxin proteins. A deduced amino acid sequence of the CTrx-h showed the highest sequence identity with those of Arabidopsis thioredoxin-h2 (75.2%) and thioredoxin-h5 (46.6%) proteins, but it shared a low sequence homology to other isotypes of plant thioredoxinm and thioredoxin-f. The CTrx-h protein that is expressed in E. coli represented not only an insulin reduction activity, but also electron transferring activity from NADPH to thioredoxin-dependent peroxidase. A genomic Southern blot analysis using the cDNA insert of CTrx-h revealed that the gene consisted of a small multigene family in Chinese cabbage genome. On the contrary to other thioredoxin-h proteins that were widely distributed in most tissues of the plant, the CTrx-h was predominantly expressed in flowers. The expression was very low in other tissues. The data of the Northern blot analysis suggests that the CTrx-h may have other functions in flower development or differentiation, in addition to its defensive role.

Wild-type V. vulnificus cannot grow using lactose as the sole carbon source or take up the sugar. However, prolonged culture of this species in media containing lactose as the sole carbon source leads to the generation of a spontaneous lactose-utilizing (LU) mutant. This mutant showed strong ${\beta}$-galactosidase activity, whereas the wild-type strain showed a barely detectable level of the activity. A mutant with a lesion in a gene homologous to the lacZ of E. coli in the bacterium no longer showed ${\beta}$-galactosidase activity or generated spontaneous LU mutants, suggesting that the lacZ homolog is responsible for the catabolism of lactose, but the expression of the gene and genes for transport of lactose is tightly regulated. Genetic analysis of spontaneous LU mutants showed that all the mutations occur in a lacI homolog, which is located downstream to the lacZ and putative ABC-type lac permease genes. Consistent with this, a genomic library clone containing the lad gene, when present in trans, made the spontaneous LU mutants no longer able to utilize lactose as the sole carbon source. Taken together with the observation that excessive amounts of exogenously supplemented possible catabolic products of lactose have negative effects on the growth and survivability of V. vulnificus, we suggest that V. vulnificus has evolved to carry a repressor that tightly regulates the expression of lacZ to keep the intracellular toxic catabolic intermediates at a sublethal level.

Objective: The aim of this systematic review was to investigate for effective strategies to improve home exercise program (HEP) adherence in vestibular rehabilitation (VR). Design: Systematic review. Methods: A systematic review was conducted to identify effective strategies used to improve HEP adherence of patients in VR. Six databases, Academic Search Premier, Cochrane Library, CINAHL, PUBMED, PsycINFO, and Web of Science were searched from their inception to December 31, 2015. The keywords used for search were 'home program', 'home intervention', 'compliance', 'adherence', 'vestibular rehabilitation', 'motion sickness', and 'motion sensitivity'. Results: A total of eight studies were selected to be included in the review. There was 95.2% agreement between the two reviewers who reviewed the studies using a quality assessment tool. The overall inter-rater agreement (${\kappa}$=0.73) showed good agreement between the reviewers. Strong evidence was identified for 3 major categories of effective HEP adherence strategies, 1) providing patient with written summary of HEP; 2) asking patient to maintain a record of HEP and symptoms; and 3) providing tele-rehabilitation in form of email and/or telephone support along with in person treatment sessions. Also, based on strong evidence, computerized technology was not found to be superior to other strategies for improving patients' HEP adherence in VR. Conclusions: The effective strategies for improving HEP in VR include written summary of exercise, maintenance of log of HEP and symptoms and tele-rehabilitation along with in person treatment sessions.

The majority of recent intrusions reveal that the attackers do not use the previous intrusion techniques or network flaw, rather they tend to use the vulnerabilities residing inside the program, which are the running programs on the system or the processes for the service. Therefore, the security managers must focus on updating the programs with lots of time and efforts. Developers also need to patch continuously to update the program, which is a lot of burden for them. In order to solve the problem, we need to understand the vulnerabilities in the program, which has been studied for some time. And also we need to analyze the functions that contains some vulnerabilities inside. In this paper, we first analyzed the vulnerabilities of the standard C library, and Win32 API functions used in various programs. And then we described the design and implementation of the automated scanning tool for writing secure source code based on the analysis.

Purpose: The aim of this study was to provide basic data on the intervention for depression program development and application by analyzing the depression intervention studies for women that were published in Korea Journal (2000~2014). Methods: The research method used was the integrative review. Nine studies were reviewed from the Nursing Articles and National Assembly Library of which 41 studies were from 126 research papers that met the inclusion criteria and analyzed using MINORS (Methodological Index for Non-Randomized Studies) and according to general characteristics. Results: There were non-equivalent control group pre-post test design (78%) in research design. 44% of articles in sample size were 14~26 participants and measuring tools were used CES-D (29%), BDI (I & II, 22%), GDSSF-K (22%). In quality of research according to MINORS, most of the papers got 2 scores except for the items of sample size calculation standard. Even though the similar intervention program were reported, the results could not compare because of diverse contents, duration, methods, and measuring tool with intervention program. As the results, aroma, massage, and counseling programs seemed to have significant effects of depression alleviation. Conclusion: The standard tailored program and measuring tool for depression alleviation of women was needed to develop.

This study analyzes the common space of the high schools before and after the decade of 2009 which starts Subject-centered clusters school plan, and proposes the direction of common space planning for the future. Based on the floor plans of high schools awarded as excellent school facilities every year, first, types and numbers of common space, second, area ratio between common space and program space and also moving space and staying space, third, space connections were analyzed for tracking the change of the relationship between common, staying and program spaces. The study results demonstrated that types, numbers and area ratio of the common space were increased as the years go on. Especially, the area ratio of staying space was dramatically increased after 2009 and this result was caused by the home-base, alcove space, and hall that were adopted for subject-centered clusters planning after 2009. Connecting diagram of staying area and program spaces also shows the spaces related to staying area were changed from a classrooms and administrative office etc. to a library, gym, and seminar rooms etc. In case of staying area, it would have a value as a common space for various student activities such as group activities, meetings, and multi-uses. Because student activities would be changed and encouraged depending on the location, sizes and program spaces around staying area, it should be emphasized that the planning for staying area is critical for future school design.

Bacterial cellulose (BC) has outstanding physical and chemical properties, including high crystallinity, moisture retention, and tensile strength. Currently, the major producer of BC is Komagataeibacter xylinus. However, due to limited tools of expression, this host is difficult to engineer metabolically to improve BC productivity. In this study, a regulated expression system for K. xylinus with synthetic ribosome binding site (RBS) was developed and used to engineer a BC biosynthesis pathway. A synthetic RBS library was constructed using green fluorescent protein (GFP) as a reporter, and three synthetic RBSs (R4, R15, and R6) with different strengths were successfully isolated by fluorescence-activated cell sorting (FACS). Using synthetic RBS, we optimized the expression of three homologous genes responsible for BC production, pgm, galU, and ndp, and thereby greatly increased it under both static and shaking culture conditions. The final titer of BC under static and shaking conditions was 5.28 and 3.67 g/l, respectively. Our findings demonstrate that reinforced metabolic flux towards BC through quantitative gene expression represents a practical strategy for the improvement of BC productivity.
