The variable cowpea productivity across diff erent environments demands evaluating the performance of genotypes in a breeding program prior to their release. The aim of this study was to assess yield stability of eight cowpea advanced breeding lines selected from participatory varietal selection in multilocational trials, and to identify mega-environments for cowpea production in Ghana. The genotypes were evaluated across fi ve environments in 2016 and 2017 in randomized complete block design with three replications. The GEA-R version 4.0 software was used for genotype main eff ect plus genotype by environment interaction (GGE) biplot analyses. Analysis of variance (PROC GLM of SAS using a RANDOM statement with the TEST option) detected signifi cant variations for location, year, genotype, environment, and their interactions. The results showed that the yield performances of the cowpea genotypes were highly infl uenced by genotype × environment interaction eff ects. The principal component 1 (PC1) and PC2 were signifi cant components which accounted for 46.75% and 22.84% of GGE sum of squares, respectively. We showed for the fi rst time, two mega-environments for cowpea production and testing in the major cowpea production agro-ecologies in Ghana. The genotypes SARI-6-2-6 and IT07K-303-1 were adapted to Damongo, Nyankpala, and Tumu, whereas SARI-2-50-80 was adapted to Yendi and Manga. The best ranking location was Damongo followed by Tumu, and Nyankpala. The high-yielding genotypes, IT86D-610, IT10K-837-1, IT07K-303-1, and SARI-2-50-80 had signifi cant higher grain yields than the check (Bawutawuta) and were recommended for release as cultivars (or as breeding lines) to boost cowpea production in Ghana.

Effect of Emotional Intelligence Training and Cognitive Restructuring Therapy on Self-Esteem of Secondary School Students Experiencing Academic Failure in Ibadan, Oyo State, Nigeria

Stephen Oluwaseun Emmanuel,Moses Oluwafemi Ogundokun 강원대학교 인문과학연구소 2023 Journal of Humanities Therapy Vol.14 No.1

Students experiencing academic failure often get the feeling of rejection from their parents, peers, teachers among others which ultimately impacts on their self-esteem. They evaluate themselves based on the subjective opinion from peers which may cause individuals to judge themselves worthy or unworthy based on the feedback they get from others. This study therefore examined the use of emotional intelligence training and cognitive restructuring on self-esteem of secondary school students experiencing academic failure in Ibadan, Oyo State, Nigeria. The moderating effects of gender and academic motivation were also examined. A pretest-posttest, control group, quasi-experimental design with a 3x2x3 factorial matrix was adopted. A multi-stage sampling procedure was employed. Three local government areas were randomly selected from Ibadan, Oyo State, Nigeria. One public Senior Secondary School were randomly selected from each of the local government area. 120 (M= 53, F=67) senior secondary school students 2 who were experiencing academic failure were screened for the self-esteem and were randomly assigned to Emotional Intelligence Training (40), Cognitive Restructuring Therapy (40) and Control Group (40). Treatment lasted for eight weeks training for emotional intelligence training Journal of Humanities Therapy, Humanities Institute, Kangwon National University, Korea 2023, vol.14-1, pp.75~104 https://doi.org/10.33252/jht.2023.6.14.1.75 ISSN 2765-2653(Online) 76 Stephen Oluwaseun Emmanuel ; Moses Oluwafemi Ogundokun_ Effect of Emotional ... Ⅰ. Introduction Students experiencing academic failure often get the feeling of rejection from parents, peers, and teachers, among others; this feedback may reduce their self-esteem. The impact of self-esteem on a variety of outcomes has been the subject of numerous studies in different disciplines of psychology (e.g., Orth, Robins, Widaman, and Conger, 2014; Pyszczynski, Greenberg, Solomon, Arndt, and Schimel, 2004). In the past, researchers considered having a high level of self-esteem as being wholly positive (Baumeister, Heatherton, and Tice, 1993). According to Diener and Diener (1995), having a high self-esteem was linked to a number of favourable outcomes, including life satisfaction and academic performance (Bowles, 1999). Contrarily, low self-esteem was mostly associated with negative outcomes like depression and poor academic performance (Crocker and Park 2004; DeWit, Adlaf, Offord, and Ogborne, 2000). and cognitive restructuring therapy groups. Data were analysed using Analysis of Covariance (ANCOVA) and Multiple Classification Analysis at the 0.05 level of significance. The results indicated that there was a significant main effect of treatments on self-esteem of the participants experiencing academic failure. There was no significant interaction effect of academic motivation and gender on self-esteem of students experiencing academic failures. Both Emotional Intelligence Training and Cognitive Restructuring Therapy were effective in managing self-esteem of students experiencing academic failure. It was recommended that Counselling Psychologists and Educational Psychologists should utilise these therapies to manage self-esteem of students.

An Efficient and Intelligent Intrusion Detection and Response System using Virtual Private Networks, Firewalls and Packet Filters

Emmanuel Hooper 보안공학연구지원센터 2007 International Journal of Security and Its Applicat Vol.1 No.1

There major challenges for current Intrusion Detection Systems (IDS) which attempt to identify suspicious network traffic. Due to the high percentage of alerts generated by such systems, the level of false positives is among the significant problems. We present intelligent strategies for reduction of false positives and infrastructure protection using a novel approach using adaptive responses from firewall packet filters in what we call, network quarantine channels (NQC). This involves using an efficient and intelligent intrusion detection and response system using Virtual Private Networks, firewalls and packet filters. The firewall packet filters provide effective intelligent responses by to granting access to the normal packets and denying malicious traffic access to the network, after the identity of the connections are verified through the statistical analysis in the NQC. These effective strategies reduce false positives and increases detection capability of the IDS

Hypotheses on the Diachronic Development of the Akan Language Group

Emmanuel Nicholas Abakah 세종대학교 언어연구소 2016 Journal of Universal Language Vol.17 No.1

There is controversy over the use of the term Akan by reason of the fact that it has both linguistic and ethnographic semantic readings. Not all the Akan people speak the Akan language and not all those who speak Akan as mother tongue can be technically classified as Akan people since some of their cultural practices deviate from that which sets the Akan people apart from other ethnic groups in Ghana and the West African sub-region in general. Hence, we begin this paper by telling between the ethnographic Akan and linguistic Akan in the cause of educating the target readership about who the speakers of the Akan language are and/ or are not. We also establish seven vowels as constituents of the *Proto-Akan vocalic inventory. This study is mainly based on evidence from the Akan synchronic phonology in respect of selected varieties of that language group which unquestionably represent all the varieties of the language group including those that are not mentioned in this study. We have asserted that *Proto-Akan had thirteen consonants in its segmental catalogue and also provided pieces of evidence from both synchronic Akan and English lexemes borrowed into the Akan Language Group to give credence to our hypothesis that all consonants apart from the 13 *proto ones developed into the language group through miscellaneous phonological processes. All analytical discussions in this paper have been done within the theories of comparative method and internal reconstruction.

Objectives This study evaluated the amount of remaining root canal filling materials after retreatment procedures performed by undergraduate students using manual, rotary, and reciprocating techniques through micro-computed tomographic analysis. The incidence of instrument fracture and the instrumentation time were also evaluated. Materials and Methods Thirty maxillary single rooted teeth were prepared with Reciproc R25 files and filled with gutta-percha and AH Plus sealer by the continuous wave of condensation technique. Then, the specimens were assigned to 3 groups (n = 10), according to the retreatment technique used: manual, rotary, and reciprocating groups, which used K-file, Mtwo retreatment file, and Reciproc file, respectively. Retreatments were performed by undergraduate students. The sample was scanned after root canal filling and retreatment procedures, and the images of the canals were examined to quantify the amount of remaining filling material. The incidence of instrument fracture and the instrumentation time were recorded. Results Remaining filling material was observed in all specimens regardless of the technique used. The mean volume of remaining material was significantly lower in the Reciproc group than in the manual K-file and Mtwo retreatment groups (p < 0.05). The time required to achieve a satisfactory removal of canal filling material and refinement was significantly lower in the Mtwo retreatment and Reciproc groups (p < 0.05) when compared to the manual K-file group. No instrument fracture was observed in any of the groups. Conclusions Reciproc was the most effective instrument in the removal of canal fillings after retreatments performed by undergraduate students.

Emmanuel Owusu Kyere,Ece Bulut,M. Dilek Avşaroğlu,Yeşim Soyer 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.3

Some strains of Escherichia coli can be important food borne pathogens. Characterization and antimicrobial resistance testing of 28 E. coli isolates from random food samples obtained in Van, Turkey were performed. Primers for 6 indicator genes (fliC, stx1, stx2, eae, hlyA, and rfbE) for shiga toxin-producing E. coli and 5 indicator genes for each pathogroup (bfpA, aggR, ipaH, daaD, st, and lt) were used. E. coli isolates were also typed using pulsed field gel electrophoresis with the XbaI restriction enzyme. Antimicrobial susceptibility of E. coli isolates was determined using the disk diffusion method for 17 antimicrobials. E. coli isolates were non-pathogenic strains represented by 25 distinguishable PFGE patterns. Antimicrobial susceptibility testing revealed that more than 40% of the E. coli isolates showed resistance to ampicillin, sulphafurazole, and tetracycline. Antimicrobial susceptibility of commensal E. coli should be monitored because these bacteria are becoming reservoirs of antimicrobial resistance genes.

A Convergence study on the Nano Technology & Nano Art

Emmanuel K. W. OH(오규운),Kim, Kyung Hoon(김경훈) 한국전시산업융합연구원 2016 한국과학예술융합학회 Vol.25 No.-

Since the announcement of U.S National Nano technology Initiative (NNI) (2000.1), national comprehensive plans have been established in the world and governmental investment and studies on the convergence of Nano technology and Nano art have been made actively. At present, however, limited convergence is known in Nano technology and art, Nano technology and construction sector in Korea but there are only a few studies on active convergence with Nano technology and Nano art, that is, art, design field yet. Therefore, studies on convergence of Nano technology and Nano art should create new and creative value of the future and an opportunity that can be evolved into a newer type should be provided. The background and purpose of this study were made in this respect and method and scope of the study are as follows: First, we identify the possibility of research on convergence with science of arts, especially Nano art and ripple effect of Nano technology through theoretical review, summary of Nano art and Nano technology. Second, we analyze the cases of studies on a variety of convergence of Nano technology and Nano art through case studies and third we understand the art world and contents of Eduardo Kac, the master of Bio Art and Cris Orfescu, the master of Nano art 21 Project. The findings of this study and the contents are as follows: First, Nano technology has the feature that it can be applied to most original technology fields and plays a key role in the convergence with new technologies such as IT, BT and the effect will be even greater in the future. Second, it means that along with the convergence of science and technology, Nano technology is setting up a base to be applied and used in the cutting-edge industries in the future with solidarity with other various sectors such as architecture, humanities, science of arts, Nano art and especially recent development of 3D printing scanning technology results in the expansion of the scope of the product design and arts fields. Third, as shown in the example of Orfescu’s SEAD(Sciences, Engineering, Arts & Design) White Paper, the activation of production method of Nano art works, online international competition and festival is necessary and active industry-university-institute convergence research of related experts, scientists, artists and designers, nano companies and policy considerations of relevant authorities is needed.

Characterization of Cassava Fiber of Different Genotypes as a Potential Reinforcement Biomaterial for Possible Tissue Engineering Composite Scaffold Application

Emmanuel Diabor,Paul Funkenbusch,Elsie Effah Kaufmann 한국섬유공학회 2019 Fibers and polymers Vol.20 No.2

Cassava bagasse contains considerable amount of natural single elementary cellulose fibers and white thick root fiber (thick-core fiber) that has seen frequent application in the packaging industry as reinforcement for plastic composite development. However, a review of the literature was unable to find any study that characterized the material properties (such as tensile properties) of both the single elementary and white thick-core cassava cellulose fibers), and their application as potential reinforced filler in tissue engineering scaffold development. In this study, the tensile properties, morphology, crystallinity and thermal degradation profile of non-chemically treated single elementary cellulose fibers and thick-core fibers of different cassava genotypes were investigated. Fibers were tested according to ASTM C1557 under direct tension in a standard mechanical testing system and the cross-sectional area of the fractured regions of the fibers were determined usinga 3D optical microscopy method. Cassava fibers of different genotypes did not show any significant difference in tensile properties, with average tensile strength ranging from (5.1-7.3 MPa), Young’s modulus (258-333 MPa) and failure strain (3.4-4.2 %). Tensile test conducted for several gage lengths did not influence the tensile strength and Young’s modulus of the fibers, however, strain-at-break depended on gage length. Single elementary and thick-core fibers showed similar surface morphology, degree of crystallinity (ranging from 21-40 %) and tensile properties with some variation in elastic modulus. Cassava fibers are thermally stable around 100-200 oC, where processing could be performed. Preliminary results showed an improvement in the mechanical properties of a gelatin scaffold when cassava cellulose microfibers were used as reinforcing fillers. The current findings show that cassava fiber has a reasonable mechanical strength, stiffness and thermal stability, and could be considered as a reinforced biomaterial to improve the mechanical integrity of tissue engineering scaffolds.
