Emendo – A Toolchain for Creating Gamified Learning Arrangements for Online Learning Settings

[EN] This contribution describes the Emendo toolchain which enables the effective creation and implementation of gamified learning arrangements for online learning settings based on the domain-specific modeling approach. The components of Emendo are a domain-specific modeling language, a generator which transforms models based on the language into source code as well as the embedding of the latter in a learning management system. Scenarios for the usage of Emendo for teaching and learning are presented with respect to the functionalities of the toolchain. In addition, a qualitative evaluation concerning Emendo’s goals, concept and insights on the results is given. The evaluation shows that Emendo reaches high acceptance for teaching purposes and can serve as a promising means for the digitisation of teaching and learning.http://ocs.editorial.upv.es/index.php/HEAD/HEAD18Bartel, A.; Hagel, G.; Wolff, C.

Feedback-based Learning Through Online Feedback Systems in Higher Education

[EN] From scientific research it is known that feedback from students to lecturers can positively influence teaching and learning in higher education. This involves both responses concerning the quality of teaching and to the own learning process. In lessons with a large number of students it appears to be challenging to realize such kind of interaction in oral way with all students in class. One possible way is to use online feedback-systems. Through this, all students have the opportunity to express their opinion, requests or problems concerning the lecture in anonymous way any time. Furthermore, it allows discussing the results together in class. The paper deals with the issue of student feedback in higher education and presents an online feedback-system and its integration into the teaching process. In addition, the paper shows some empirical based experiences made with the feedback-system in three courses in a German University of Applied Sciences. It becomes visible that feedback-systems have the potential to improve the quality of teaching and make learning more interactive and student-oriented.This work is part of the EVELIN project which is supported by the Bundesministerium für Bildung und Forschung with the project number 01PL12022C.Figas, P.; Bartel, A.; Hagel, G.

Effective Integration of Gamification and Learning Management Systems for Creating Gamified Learning Arrangements

[EN] This paper describes ongoing research concerning the effective development of gamified learning arrangements. It shows the necessity for more standardization of the design of such arrangements and reveals potential ways in order to support this need with the use of a domain-specific modeling language. The latter is used by lecturers for designing and exchanging models of gamified learning arrangements and provides the possibility to automatically generate a working learning management system using a language specific generator. The generated learning management system can directly be used by learners and furthermore allows to track the individual learning process for both learners and lecturers.Bartel, A.; Hagel, G.; Wolff, C.

Ganzheitlichkeit in der Lebensmittelmittelforschung

Ein Grund für die bislang schwierige bis unmögliche anbauspezifische Zuordnung frischer oder verarbeiteter landwirtschaftlicher Erzeugnisse besteht nach Ansicht von Wissenschaftlerinnen und Wissenschaftlern aus privaten und staatlichen Forschungseinrichtungen des Öko-landbaus in der Art der angewendeten analytischen Methoden zur Qualitätsbewertung. Wäh-rend fast alle gängigen chemisch-analytischen Methoden für eine Differenzierung offensicht-lich nicht genügen, scheinen verschiedene, gegenwärtig jedoch naturwissenschaftlich nicht anerkannte, komplementäre Analysenmethoden eine Unterscheidung treffen zu können. Diese schreiben der Lebensmittelstruktur, äußerer Form, Formerhalt und innerer Formation als Qua-litätskriterium eine besondere Bedeutung zu und können so zwischen verschiedenen Produk-tionsverfahren, Sorten, Verarbeitungsgraden u.a. unterscheiden. Die komplementären Methoden sind jedoch im Hinblick auf ihre Spezifität zur Unterschei-dung der Produktionsverfahren, Vergleichbarkeit, Präzision, Robustheit noch umfassend zu validieren. Obwohl die komplementären Methoden auch nach dieser Validierung nicht notwendigerweise Aussagen über die Qualität der Lebensmittel aus unterschiedlichen Produktionsverfahren zulassen, ist die Möglichkeit der Unterscheidung von konventionell erzeugten Lebensmitteln und Bio-Lebensmitteln gleichwohl von hohem Interesse. Die SAG empfiehlt daher ausdrücklich die Validierung der beschriebenen ganzheitlichen Methoden auf naturwissenschaftlich-statistischer Grundlage zu komplementären Methoden der Qualitätserfassung

Vertical hydraulic conductivity of borehole heat exchanger systems before and after freeze-thaw cycle stress

Quality assurance is a very important aspect in the planning, implementation and operation of borehole heat exchangers (BHE). Within the research project Quality Assurance for Borehole Heat Exchangers (QEWS) the hydraulic sealing behaviour of industrial grouting materials was investigated. Important aspects therein were the capability for sealing between different aquifers and aging resistance against freeze-thaw cycle stress. For this purpose, a large-scale test rig for determining the hydraulic conductivity of borehole heat exchanger systems (BHES) was developed and put into operation. Compared to samples of the pure grouting material, the system samples exhibited significantly increased permeability, which was further increased by freeze-thaw cycle stress. It could be shown that the first freeze-thaw cycle caused the most significant aging effect. Aging caused by further freeze-thaw cycles could be partly compensated by regeneration effects. But the large-scale test rig has a substantial disadvantage: due to the length of the system sample, depending on the hydraulic permeability of the grouting material, the experimental program is very complex and time-consuming. Therefore, a downscaled test rig will be developed within the current project Quality Assurance for Borehole Heat Exchangers II (QEWS II)

Brown bowel syndrome: A rare complication in diseases associated with long-standing malabsorption

BACKGROUND/AIMS Longtime chronic malabsorption may among other things cause a lack of liposoluble vitamins. Vitamin E deficiency can lead to formation of lipofuscin aggregates. Its deficiency is also associated with an increased lipofuscinosis of the bowel, i.e. brown bowel syndrome. METHODS Systematic research via Medline on brown bowel syndrome, lipofuscinosis, and vitamin E deficiency was performed. We combined our own clinical experience and a review of the literature for this paper. Its goal is to inform about the possible consequences of severe malabsorption and brown bowel syndrome. RESULTS Systematic data about the occurrence of severe malabsorption and brown bowel syndrome are rare. Only about 27 scientific reports can be found on this subject. Brown bowel syndrome is found mostly in conjunction with vitamin E deficiency and lipofuscinosis of the bowel. The clinical findings are caused by both malabsorption and lipofuscinosis. Case reports show a therapeutic effect of vitamin E. CONCLUSION Vitamin deficiency caused by longtime chronic malabsorption can lead to the development of brown bowel syndrome, which is seen as the expression of lipofuscinosis of the bowel, and can cause further clinical disorders. Patients with malabsorption should therefore be monitored regarding their vitamin E levels

Eosinophilic gastroenteritis with refractory ulcer disease and gastrointestinal bleeding as a rare manifestation of seronegative gastrointestinal food allergy

Gastrointestinal bleeding and iron deficiency anaemia may cause severe symptoms and may require extensive diagnostics and substantial amounts of health resources. This case report focuses on the clinical presentation of a 22 year old patient with recurrent gastrointestinal bleeding from multilocular non-healing ulcers of the stomach, duodenum and jejunum over a period of four years. Extensive gastroenterological and allergological standard diagnostic procedures showed benign ulcerative lesions with tissue eosinophilia, but no conclusive diagnosis. Multiple diagnostic procedures were performed, until finally, endoscopically guided segmental gut lavage identified locally produced, intestinal IgE antibodies by fluoro-enzyme-immunoassay. IgE antibody concentrations at the intestinal level were found to be more-fold increased for total IgE and food-specific IgE against nuts, rye flour, wheat flour, pork, beef and egg yolk compared with healthy controls. Thus, a diet eliminating these allergens was introduced along with antihistamines and administration of a hypoallergenic formula, which resulted in complete healing of the multilocular ulcers with resolution of gastrointestinal bleeding. All gastrointestinal lesions disappeared and total serum IgE levels dropped to normal within 9 months. The patient has been in remission now for more than two years. Eosinophilic gastroenteritis (EG) is well known to induce refractory ulcer disease. In this case, the mechanisms for intestinal damage and gastrointestinal bleeding were identified as local gastrointestinal type I allergy. Therefore, future diagnostics in EG should also be focused on the intestinal level as identification of causative food-specific IgE antibodies proved to be effective to induce remission in this patient
