Short-palped crane flies belonging to the genus Epiphragma Osten Sacken, 1860 (Diptera: Limoniidae: Limnophilinae) have a worldwide distribution except the Afrotropics, with the highest diversity in Neotropics and Oriental Region. They are divided into four subgenera: Eupolyphragma Alexander, 1948, Epiphragma s. str., Lipophragma Alexander, 1978, and Parepiphragma Alexander, 1960. Diagnostic characters and wing photographs of all subgenera are given. Genus Epiphragma was previously unknown from the Korean Peninsula. Species Epiphragma (Epiphragma) gracilistylus Alexander, 1933 is newly recorded for North Korea, E. (E.) subfascipenne Alexander, 1920 is newly recorded for South and North Korea, and E. (E.) subinsigne Alexander, 1920 is newly recorded for South Korea. These species are taxonomically revised, and the taxonomic status of E. (E.) gracilistylus is discussed. We present an identification key and redescriptions and illustrations of both sexes from all species in Korea. Redescription of larva and pupa of E.(E.) subfascipenne is presented. Elevation range, period of activity, habitat information, general distribution, and a distribution map in Korean Peninsula is given for each species.

In this study, we elucidated anti-cancer activity and potential molecular mechanism of 70% ethanol extracts from Taxilli Ramulus (Taxillus chinensis (DC.) Danser) (TR-E70) against human colorectal cancer cells. Anti-cell proliferative effect of TR-E70 was evaluated by MTT assay. The effect of TR-E70 on the expression of cyclin D1 in the protein and mRNA level was evaluated by Western blot and RT-PCR, respectively. TR-E70 suppressed the proliferation of human colorectal cancer cell lines, HCT116 and SW480. Although TR-E70 decreased cyclin D1 expression in protein and mRNA level, decreased level of cyclin D1 protein by TR-E70 more dramatically occurred than that of cyclin D1 mRNA. Cyclin D1 downregulation by TR-E70 was attenuated in presence of MG132. In addition, TR-E70 phosphorylated threonine-286 (T286) of cyclin D1. TR-E70-mediated cyclin D1 degradation was blocked in presence of LiCl as an inhibitor $GSK3{\beta}$ but not PD98059 as an ERK1/2 inhibitor and SB203580 as a p38 inhibitor. Our results suggest that TR-E70 may downregulate cyclin D1 as one of the potential anti-cancer targets through $GSK3{\beta}$-dependent cyclin D1 degradation. From these findings, TR-E70 has potential to be a candidate for the development of chemoprevention or therapeutic agents for human colorectal cancer.

The present study investigates the impact of perceived value metrics in driving satisfaction and behavioral intention to use e-resource among its users. Utilitarian, hedonic, uniqueness, epistemic, and economic are key values selected for the purpose of investigation in the study. This empirical study is carried out through a survey and responses have been analyzed using structural equation modelling. The target group is selected by means of simple random sampling (users of e-resources in selected business schools). Findings of the study reveal that utilitarian values, hedonic values, epistemic values, and uniqueness values have a significant impact on the usage intention of e-resources; however, economic values reflect an insignificant relationship to intention to use e-resources. The study is a distinctive piece of work on investigating the most and the least significant value(s) associated with satisfaction and usage intentions of e-resources.

Introduction. Inadequate methods for acquiring user education could affect the level of library user education possessed by postgraduate students, and ultimately influence the purposes of their usage of e-resources provided in their university libraries. Despite the global acceptance that e-resources are contributing to postgraduate student’s research work, however, it has been documented that there is low use of e-resources in university libraries in Nigeria among postgraduate students. This drift could have negative consequences on their overall development. Therefore, this study determined how influential library user education is on the use of e-resources by postgraduate students in Nigerian university libraries.Methods. A survey research design and multi-stage sampling technique was adopted to select 2,726 from 54,578 postgraduate students from four faculties in 16 federal conventional universities in Nigeria. The data set was collected using a questionnaire and an interview schedule for e-resources librarians/system librarians and was analysed using percentage and Pearson’s product moment correlation.Results. The majority of the students were at the Master’s level (57.5%). The gender shows a ratio of 59.0% male and 41.0% female. Most Nigerian students enrol for postgraduate programmes in their thirties ‘30-39’ years. The use of e-resources by the postgraduates was low (weighted average of 2.45). The relationship between level of library user education and postgraduate students’ use of e-resources was positive, slightly strong, and significant (r = 318; df = 2284; p< .05).Conclusion. User education has positively inclined postgraduate students to the use of e-resources in their libraries. Therefore, libraries should employ all methods for acquiring user education for postgraduate students.

This study examined e-resources usage among polytechnic students in Southwest Nigeria. A descriptive research design was adopted for this study and the population consisted of polytechnic students from The Polytechnic, Ibadan and Federal Polytechnic, Ede. There were 9671 students from both polytechnics. A multi-stage sampling technique was employed with a sample fraction of 5% was drawn from the total number of students in each faculty amounting to 381. A structured questionnaire was the major instrument used for data collection and the questionnaire was pre-tested using Cronbach-alpha to determine the reliability co-efficient. Data obtained was analyzed using SPSS. The study found that the students from both polytechnics are aware of the e-resources and that the e-resources were mainly used for research, class assignment and to update knowledge. The problem such as epileptic power supply, poor internet connection and so on was identified. The study concluded that polytechnic students could benefit immensely from the enormous usage of e-resources particularly for teaching, learning and research. Based on the findings, recommendations were made.

The present study examines the impact of value co-creation on satisfaction and intention to adopt of e-resources among users. Four components of the DART model have been adopted to describe value co-creation. These components are dialogue, access, risk-assessment, and transparency. Ph.D. scholars and faculty members from National Capital Region, India, were requested to respond on a five-point Likert scale. A total of 220 responses were collected with the help of a structured questionnaire from respondents of the top 50 business schools according to National Institute Ranking Framework. These responses have been analysed by means of structured equation modelling on Adanco 2.2 software. Findings of the study reported the insignificant impact of access and risk-assessment, and positive impact of dialogue and transparency on satisfaction. Further, satisfaction has been identified, creating significant impact on adoption of e-resources. Such findings reflect the real picture of customer experience with respect to their role in co-creation of e-resources. Respondents have conveyed their dissatisfaction with the co-creation process of e-resources, as companies do not provide all the information and access to their customers beforehand. Consequently, customers fail to make informed decisions and also find themselves unable to show trust in the service providers of e-resources.
