The purpose of this study was to evaluate the prophylactic effect of Pimpinella anisum (green anis) on neurobehavioral status following mercury chloride intoxication during the developmental period. For this purpose, rats exposed to 100 mg/L of HgCl2 during the gestation and lactation period. A group of rats was treated with the anis extract for 15 days before becoming intoxicated with mercury. In contrast, one group was orally administered aqueous anis extract for 15 days after intoxication. The forced swimming test, the open field test and the Morris pool respectively recorded an increase in immobility time, a decrease in the number of cross-cells (p <0.001), (p <0.05) and an increase in latency (p <0.01), (p <0.001), (p <0.001) and decreased time spent in the target frame during the probe test (p <0.01) and increased latency in the visible test (p <0.01) in HgCl2 - exposed rats compared to control rats. However, preventive and curative aniseed-based treatment reduced the rate of depression, increased locomotor activity and improved learning performance. In conclusion, the aqueous extract of Pimpinella anisum could have a corrective effect on some neurological disorders caused by mercury.

Purpose This case study aims to analyze and compare the learning achievements of two groups of university students taught by: traditional face-to-face learning (TDL) and blended e-learning (BEL). To the best of the authors’ knowledge no previous study of the use of BEL in the context of Thailand has addressed the same purpose as this study. It is expected that the findings from this study will suggest areas for additional research and will be of interest to researchers and professional educators, especially those involved in the development and use of BEL systems. Design/methodology/approach This case study compares two groups of undergraduate students who completed a course designed to develop skills in using productivity software at a university in Thailand. After establishing the groups, one group learned in a BEL environment and the other in a TDL environment. In particular, the online training and assessment software application SIMnet was used in the BEL environment. Comparisons between results using BEL and TDL are made for different assessment results. Additional analyses of results for the BEL group examined gender differences and correlations between the number of attempts made on assessments and the levels of achievement. Findings The findings indicated that for all of the assessments, the BEL group had a better performance than the TDL group. For the BEL group, additional analyses found no significant differences between the achievements of males and females and significant correlations between the numbers of attempts made on assessments and the results. Limitations of this case study are discussed, and the findings are expected to be of interest to researchers and professional educators, especially those involved in the development and use of BEL. Research limitations/implications Learning content was restricted to the Excel spreadsheet in which different areas of content need to be studied. The software SIMnet was used by the BEL group, additional BEL software needs to be studied. The participants’ characteristics – age, gender, culture and computer competency – were narrow scoped in which the study could include more varieties and also a larger sample size. Further studies should be designed to include more comparisons such a comparison between TDL group males and females. Originality/value The findings from this limited case study suggest that a BEL learning environment is superior to a TDL environment. Also, a BEL environment is equally beneficial for male and female students. In particular, the BEL feature, which allows students to retake assessments, leads to improved learning performance equally for both males and females. In general, these findings support those reported in previous studies.

Aim of the research was to improve effectiveness of university education. With the use of new digital tools the learning processes in many different disciplines have been enhanced. However, the traditional class room training can hardly be replaced entirely as the students’ motivation drops with less direct interaction with the instructor. Hence small private online courses are more successful than massive online education. The authors have developed a sophisticated flipped classroom learning approach incorporating various digital tools ranging from different kinds of videos to a class response system combined with class room lectures. The case of the course introduction to management accounting at the University of Applied Sciences Berlin is been presented to demonstrate the usefulness of the flipped classroom concept. An empirical analysis confirms that the students’ acceptance is highest if various methods of teaching are been applied. In particular relying on digital tools only is seen as ineffective and of less value. Eventually, based on the analysis and classroom observations improvement opportunities have been derived in order to further increase the learning performance.

Inferences of physiological responses are seen increasingly in dynamically adaptive environments, towards personalization, learning, and interactive instructional design. In search of conclusive interpretations, scientists consider bio-sensing and physiological metrics in addition to formal assessment methodologies. Devices developed for laboratory use impose limitations that yield them prohibitively unsuitable for wider use due to their strong dependence on electrodes and kinetic restrictions. Additionally, synchronisation, diverse format and frequencies of data produced by assorted equipment, contribute to precision concerns. The development cited in this chapter circumvents the above constraints by using a proprietary real-time system. An algorithm assessing coinciding excitation of two important physiological quantities is used to evaluate classifiers indicative to focused attention and engagement. Experiments and interpretations are delineated, exposing system accuracy and potential to assist in substantiating propositions towards improved learning performance and adaptive personalisation.

Background: Neuroinflammation and oxidative stress have significant effects on cognitive deficiency in the pathophysiological development of Alzheimer’s disease (AD). In the present study, we studied the influences of Ampelopsin (AMP) on proinflammatory cytokines (PICs, IL-1β, IL-6 and TNF-α), and products of oxidative stress 8-isoprostaglandin F2α (8-iso PGF2α, a product of oxidative stress); and 8-hydroxy-2’-deoxyguanosine (8-OHdG, a key biomarker of protein oxidation) in the hippocampus using a rat model of AD. Methods: ELISA was used to examine PICs and oxidative stress production; and western blotting to examine NADPH oxidase (NOXs). The Spatial working memory tests and Morris water maze were utilized to assess cognitive functions. Results: We observed amplification of IL-1β, IL-6 and TNF-α as well as 8-iso PGF2α and 8-OHdG in the hippocampus of AD rats. AMP attenuated upregulation of PICs and oxidative stress production. AMP also inhibited NOX4 in the AD rat hippocampus. Notably, AMP mostly improved learning performance in AD rat and this was linked to signal pathways of PIC and oxidative stress. Conclusion: AMP plays a significant role in improving the memory deficiency in AD rats via inhibition of signal pathways of neuroinflammation and oxidative stress, suggesting that AMP is likely to prospect in preventing and relieving development of the cognitive dysfunctions in AD as a complementary alternative intervention.

AbstractSince the beginning of teaching object-oriented programming at universities in the mid 90’s, university teachers are trying to come up with more effective ways of teaching. Number of researches has been made in this area. They are trying to identify errors teachers are making in learning process. These researches suggest different teaching methodologies and tools, which should help them to avoid these mistakes.The subject of this paper is to present a solution we developed to teach and illustrate basic concepts of object oriented paradigm through playing of computer game. In this approach, we are teaching basic principles, such as class, objects and relationship between them in the beginning of object oriented programming (OOP) course and postpone learning of specific objective language to later time. Also we are taking advantage of attractiveness of computer games to increase students motivation, which should lead to improved learning performance of students.

An artificial life approach is taken to explore the effect that lifetime learning can have on the evolution of certain life history traits, in particular the periods of protection that parents offer their young, and the age at first reproduction of those young. The study begins by simulating the evolution of simple artificial neural network systems that must learn quickly to perform well on simple classification tasks, and determining if and when extended periods of parental protection emerge. It is concluded that longer periods of parental protection of children do offer clear learning advantages and better adult performance, but only if procreation is not allowed during the protection period. In this case, a compromise protection period evolves that balances the improved learning performance against reduced procreation period. The crucial properties of the neural learning processes are then abstracted out to explore the possibility of studying the effect of learning more generally and with better computational efficiency. Throughout, the implications of these simulations for more realistic scenarios are discussed.
