This article is a part of a doctoral research project on developing the faculty-librarian collaboration model to support learning and research at Vietnamese universities. The findings of this study have crucial significance in drawing a broader view of the importance of faculty-librarian collaboration and the roles of such collaborators at Vietnamese universities. Qualitative methodology was used to formulate related topics and achieve these research objectives. Semi-structured interviews were carried out at four universities in Vietnam with three key informants, including the faculty, librarian, and administrators (dean/vice dean of faculty, director/deputy director of the library). From March to April 2019, researchers conducted 29 interviews with three participant groups. The striking results of this research showed that the faculty and librarians realized the significance of a collaborative relationship and expect that Vietnamese universities will design and deploy a model to boost the effectiveness of this collaboration. Besides this, the study found that the collaborators play certain important roles within the collaborative relationship, for instance, that of reference, coordinator, special lecturer, cooperator, and information user.

This study aims to understand the information needs of Korean immigrant mothers in the United States for their high school children's college preparation. A content analysis was conducted for the messages posted to a "motherhood" forum on the MissyUSA website. In total, 754 posts were analyzed in terms of a child's grade, college preparation stage, type of post, and topic of post. The study found that there is a range of information needed at different stages in a child's education. Many of the demonstrated information needs showed similarities to those of other immigrant groups, but there were also community-specific themes, such as an emphasis on STEM (science, technology, engineering, and math) and standardized tests. The forum was mainly used for factual questions, not emotional support. We concluded that the findings of the study would help researchers in understanding immigrant information needs for the college application process and how information professionals and educators could combine the needs of different ethnic groups to create customized services for them.

This paper presents and analyzes the effects of on-grid electricity cost, fuel price and initial capital cost of a CHP system, on the optimum DG and AC capacity and NPV, by using the ORNL CHP Capacity Optimizer, which was applied to a library in a university. By considering the current domestic energy cost and initial capital cost, it is shown that the installation and operation of the CHP system is not economical. However, with the current domestic CHP installation cost and fuel price, the NPV achieved by the installation of CHP system is greater when the on-grid electricity price is a factor of ${\times}1.5$ the present value. Regarding the initial capital cost of the CHP system, the reduction of the DG cost is much more economical than that of the AC cost, with respect to NPV. Electricity cost and fuel price have opposite effects on NPV, and NPV is more sensitive to an increase of the electricity cost than an increase of the fuel price.

Objective The purpose of this study was to examine the composition, bibliographic characteristics, and contents of the book, Dongeuisasangjinryoeuijeon(東醫四象診療醫典). Method The images of this book published in 1941 at Haenglim publishing company, stored in the National Library of Korea were acquired and used as basic data, and books related to Sasang constitutional medicine such as Dongeuisasangshinpyun (東醫四象新編), Dongmuyugo(東武遺稿), and Sasanggeumgyebibang(四象金匱秘方) were compared. Result Many of the data were based on the Dongeuisasangshinpyun(東醫四象新編), and were made with reference to Dongmuyugo(東武遺稿) and Sasanggeumgyebibang(四象金匱秘方) partly. This book is thought to be made to be used conveniently for clinicians at the time when data on Sasang Constitutional Medicine was insufficient. In particular, it can be said that the mention of well-established diagnostic method, drugs that cause adverse reactions when a patient of a different constitution takes them and the quatrains of prescriptions using seven Chinese characters in each line are very unique. Conclusion Although most of the books, including Dongeuisasangshinpyun(東醫四象新編), were cited, it is thought that the book was well-organized in order to provide good information to the clinicians practicing Sasang Constitutional Medicine at the time. For the original part of this book, further research should be conducted.

Objectives To evaluate the evidence supporting the effectiveness of bee venom acupuncture for ankle sprain. Methods We conducted search across 11 electronic databases (Pubmed, EMBASE, Cochrane CENTRAL [CENTRAL], KoreaMed, Kmbase, Koreanstudies Information Service System [KISS], National Digital Science Library [NDSL], Korea Institute of Science and Technology Information [KISTI], China National Knowledge Infrastructure [CNKI], Wanfang and Chinese Scientific Journals Database [VIP] database) to find clinical trials that used bee venom acupuncture as treatment for ankle sprain. The methodological quality of randomized controlled clinical trials (RCTs) were assessed using the Cochrane Risk of Bias (RoB) tool, while non-randomized controlled clinical trials (NRCTs) were assessed using the Cochrane Risk of Bias Assessment tool for Non-randomized Study (RoBANS) tool. Results Four RCTs and one nRCT met our inclusion criteria. Almost studies showed that bee venom acupuncture has positive effect on ankle sprain. 4 studies of same intervention and control included in the meta-analysis. When comparing bee venom acupuncture and acupuncture with acupuncture, the effect size of standardized mean difference (SMD) was -0.19 (95% confidence interval [CI]: -1.95~1.56, Z=0.55, p=0.83). And when comparing bee venom acupuncture with acupuncture, the effect size of SMD was -0.17 (95% CI: -0.65~0.31, Z=0.71, p=0.48). Conclusions Although our systematic review found encouraging but limited evidence of bee venom acupuncture for ankle sprain, most of the studies included in the analysis were evaluated as methodologically high risk of bias. From now on further well-designed RCTs should be encouraged.

BACKGROUND/OBJECTIVES: Vitamin D is produced in the skin during sun exposure and is also ingested from foods. The role of vitamin D needs to be considered in the prevention and management of various diseases. Moreover, since the majority of Koreans spend their days indoors, becoming susceptible to the risk of vitamin D deficiency. The current study aims to prepare a basis for determining dietary reference intake of vitamin D in Korea, by reviewing the evidence against various diseases and risks. MATERIALS/METHODS: Literature published in Korea and other countries between 2014 and 2018 was prioritized based on their study design and other criteria, and evaluated using the RoB 2.0 assessment form and United States Department of Agriculture Nutrition Evidence Library Conclusion Statement Evaluation Criteria. RESULTS: Of the 1,709 studies, 128 studies were included in the final systematic analysis after screening. To set the dietary reference intakes of vitamin D based on the selected articles, blood 25(OH)D levels and indicators of bone health were used collectively. Blood vitamin D levels and ultraviolet (UV) exposure time derived from the Korean National Health and Nutrition Examination Survey were analyzed to establish the dietary reference intakes of vitamin D for each stage of the life cycle. The adequate intake levels of vitamin D, according to age and gender, were determined to be in the range of 5-15 ㎍/day, and the tolerable upper intake level was established at 25-100 ㎍/day. CONCLUSIONS: The most important variable for vitamin D nutrition is lifestyle. A balanced diet comprising foods with high contents of vitamin D is important, as is vitamin D synthesis after UV exposure. The adequate intake level of vitamin D mentioned in the 2015 Dietary Reference Intakes for Korean (KDRI) remained unchanged in the 2020 KDRI for the management of vitamin D nutrition in Koreans.

A lightweight hardware design of self-timed ring based true random number generator (TRNG) suitable for information security applications is described. To reduce hardware complexity of TRNG, an entropy extractor with feedback structure was proposed, which minimizes the number of ring stages. The number of ring stages of the FSTR-TRNG was determined to be a multiple of eleven, taking into account operating clock frequency and entropy extraction circuit, and the ratio of tokens to bubbles was determined to operate in evenly-spaced mode. The hardware operation of FSTR-TRNG was verified by FPGA implementation. A set of statistical randomness tests defined by NIST 800-22 were performed by extracting 20 million bits of binary sequences generated by FSTR-TRNG, and all of the fifteen test items were found to meet the criteria. The FSTR-TRNG occupied 46 slices of Spartan-6 FPGA device, and it was implemented with about 2,500 gate equivalents (GEs) when synthesized in 180 nm CMOS standard cell library.
