  • As libraries strive to improve their services, many have expressed interest in implementing new technologies. One such technology is metaverse, a virtual-reality space that enables social activities using avatars. However, implementing this technology can be challenging when many librarians are unfamiliar with the concept. This study aimed to investigate how librarians' prior experiences with metaverse influence their expectations and potential use of the technology in libraries. Interviews with a total of 18 librarians were conducted. The study findings reveal that librarians had different conceptualizations of metaverse, regardless of prior experience. However, librarians had different thoughts on the potential use of metaverse for libraries dependent on prior experience. Regarding thoughts on potential use, the librarians who had non-experience running metaverse programs suggested ideas in expanding and trying out new services within metaverse. The librarians who had experience running metaverse programs, on the other hand, suggested focusing on transferring the existing services that are currently being provided in the library to metaverse.

  • The registration of a pesticide for use in the gardens or a farmer's field requires assessment of the potential negative effects of that pesticide on human health. To anticipate how a pesticide might impact human health, laboratory animals such as mice and rats are exposed to varying dosages in their foods -from very minimal to extremely high levels. Toxicologists then evaluate the observable effect(s) of consuming known quantities of that specific pesticide on acute, subchronic, chronic, mutational, reproduction and neurological effects. Information gained from such test is evaluated by toxicologists and medical experts to determine potential human effects

  • The fluoroquinolones are an important group of antibiotics widely used in the treatment of various infectious diseases in adults, as a result of an excellent spectrum of activity, good tissue penetration and convenient ways of administration. In recent decades, there has been extensive development, clinical investigation, licensure and use of fluoroquinolone antibiotics. However, the use of fluoroquinolones in children has been limited because of their potential to induce arthropathy in juvenile animals. Despite class label warnings against use in children, prescriptions for quinolone antibiotics to treat infections in children have become increasingly prevalent. The main use of fluoroquinolones in pediatrics should be, understandably, in serious life-threatening infections for which other antibiotics therapies are not effective or available. While most of the published studies failed to detect an increased rate of articular adverse effects in children treated with fluoroquinolones, an increase in the use of these compounds, particularly in community-acquired lower respiratory infections, could accelerate the emergence of multidrug-resistant (including fluoroquinolone) pneumococcal strains. This review will discus the main issues related to the use of fluoroquinolones in children, the major problems of resistance developing among these compounds, with special emphasis on the potential side effects and skilled use of these alternative potent drugs in pediatric infection.

  • Construction in the UK is the second most dangerous industry in terms of fatal and minor injuries according to the 2014 report of HSE. The use of mobile devices such as iPad, Tablets and Smart phones on the live construction projects is also on the increase in the UK due to the 2016 - Level 2 BIM (Building Information Modelling) implementation target, set by the UK Government. Hence, the use of such devices may become a distraction from work activities on the construction sites and will cause a major risk to the end users. The subject of improving safety of BIM use is widely researched, but there is a gap in knowledge about the actual use of the mobile devices and perception of 'Site BIM', on the construction site activities. The main gap identified in the 'Site BIM' is the health and safety aspect of using such devices on the construction sites. A safer way of working with such devices needs to be identified to avoid any potential site hazards and fatalities before the widespread use of the devices are found on the construction projects. In that context, the paper is aimed to highlight the safety issues that are required to address for the successful implementation of the mobile devices for safer use of the 'Site BIM'. Questionnaire survey was used to collect the site information among construction professionals in the UK. The survey findings suggested that a proactive approach may be helpful to stop potential hazards and risks causing by the use of mobile devices and potential measures need to be identified before any injuries and incidents occur. The paper concludes that training, changing size of mobile devices and ensuring a separate induction training for 'Site BIM' tools will improve the health and safety of the end users of the mobile devices at the live construction sites.

  • With wide use of nano-materials, it is increasingly important to address their potential toxicity to mammalian cells. However, toxic effects of these materials have been mainly assessed by the cell survival assays. Considering that mitochondrial morphology and quality are highly sensitive to the condition of the cells, and the impairment of mitochondrial function greatly affect the survival of cells, here we tested the impact of multi-walled carbon nanotubes (MWNT) on the survival, mitochondrial morphology, and their membrane potential in HeLa cells. Interestingly, although MWNT did not induce cell death until 24 hours as assessed by pyknotic cell assay, mitochondrial length was elongated and the mitochondrial membrane potential was significantly reduced by exposure of HeLa cells to MWNT. These results suggest that MWNT exposure is potentially harmful to the cell, and the mechanism how MWNT alters mitochondrial quality should be further explored to assess the safety of MWNT use.

  • This study aims to select eight books to see if "potential complement" is sufficiently acquired and properly used in Chinese conversation textbooks, explore the reasons and problems of learners' errors through analysis, and briefly suggest textbook compilation and teaching. Twelve criteria were established and analyzed, including the concept and format of "potential complement", layout order, location of objects, three types of forms, distinction from auxiliary verb "能" and distinction between "能+V+結果補語". Some of the results of the study are simply as follows. All eight textbooks focus only on "possibility," missing an important part of "the impact of objective conditions" that the term "potential complement" does not contain. This is certainly enough to cause confusion for learners. A poor understanding of the concept of "potential complement" results in identifying it with the possible auxiliary verb "能", and incorrect mixing because it does not know exactly what the difference is. Most of the textbooks compiled in China place a high importance on "potential complement". This means that Chinese people often use "potential complement" in real life. on the other hand relatively Korean textbooks do not deal with "potential complement" relatively importantly.

  • The agricultural reservoir watershed plan suggests three specific indices or ways to measure the potential for maintaining reservoir quality in balance with existing or proposed uses: an index of the reservoir's vulnerability to accelerated eutrophication, an index of the degree of land use intensity in reservoir watersheds, and an index of present water quality. Three items that contribute to reservoir eutrophication are included in the vulnerability index: the ratio of reservoir volume to drainage-basin area, shoreline configuration, and mean depth. The watershed land-use intensity index is based on road proximity and upland watershed land-use intensity. Water quality can be given a COD level. All six indicators are considered separately and then rated as follow: low (1), medium (2), or high (3). Five out of 30survey sites were less than 8points, 17sites were less than 11points and 8sites were less than 14points. This study suggests that the sites in the first ranking were potential areas for preservation, sites in the second ranking were potential areas for environmental friendly planning and sites in the third ranking were potential areas for residential need oriented planning. The advantage of this study is the low cost of gathering data for the development of local policy for the planning, management and protection of reservoir basin.

  • This study has tried to develop the modified DRASTIC Model by supplying the parameters, such as structural lineament density and land-use, into conventional DRASTIC model, and to predict the potential of groundwater contamination using GIS in Hwanam 2 District, Gyeonggi Province, Korea. Since the aquifers in Korea is generally through the joints of rock-mass in hydrogeological environment, lineament density affects to the behavior of groundwater and contaminated plumes directly, and land-use reflect the effect of point or non-point source of contamination indirectly. For the statistical analysis, lattice-layers of each parameter were generated, and then level of confidence was assessed by analyzing each correlation coefficient. Groundwater contamination potential map was achieved as a final result by comparing modified DRASTIC potential and the amount of pollutant load logically. The result suggest the predictability of contamination potential in a specified area in the respects of hydrogeological aspect and water quality.
