The success of the teacher in creating an interesting learning atmosphere and can foster a positive attitude of students in participating in this learning is strongly influenced by several factors, one of which is the use of interesting learning media. The purpose of this research is to produce Snakes and Ladders Game Learning Media on the Circle material for grade VI students of SDN 26 Ampenan which is suitable for use based on the assessment of Material Experts, Media Experts, and Students, as well as improving student learning outcomes. Snakes and Ladders Game Learning Media was developed using research and development or Research and Development (R&D) with the ADDIE development model. At the Development stage, the media developed was assessed for feasibility by 2 Material Experts (lecturers and teachers), 1 Media Expert, 5 Small Group Trial Students, and 25 Large Group Trial Students. Data collection techniques in this development research are through questionnaires and tests. The data obtained from the questionnaire were analyzed descriptively qualitatively and quantitatively. The results of the media assessment based on the Material Experts obtained an average score of 3.6 included in the "Very Eligible" criteria, the Media Experts obtained an average score of 3.1 included in the "Eligible" criteria, and Small Group Trial Students obtained an average score 3.5 is included in the "Very Eligible" criteria, and the Large Group Trial of Students obtained an average score of 3.4 is included in the "Eligible" criteria. Student learning outcomes after using the Snakes and Ladders Game Learning Media that has been developed have increased by 56%. It is concluded that the Snakes and Ladders Game Learning Media is acceptable, feasible and effective to be used as a learning medium.

Applying Transfer Learning Using DenseNet121 in Radiographic Image Classification: تطبيق التعلم بالنقل باستخدام شبكة DenseNet121 في تصنيف الصور الشعاعية

The study aims to apply one of the fully connected convolutional neural networks, DenseNet121 network, to a data sample that includes a large group of radiographs through transfer learning technology. Radiography technology is a very important technique in the medical community to detect diseases and abnormalities that may be present, but the interpretation of these images may take a long time and it is subject to error by radiologists who are exposed to external practical factors (such as fatigue resulting from working for long hours, or exhaustion, or thinking about other life matters). To assist radiologists, we have worked on developing a diagnostic model with the help of a deep learning technique to classify radiographic images into two classes: (Normal and Abnormal images), by transferring the selected deep convolutional neural network between a large group of available networks that we studied on the basis of the regions that possibly abnormalities provided by the radiologists for the study sample. We also studied the feasibility of using the well-known VGG16 model on the same data sample and its performance through transfer learning technology and compared its results with the results of the DenseNet121 network. At the end of the research, we obtained a set of good results, which achieved a high diagnostic accuracy of 87.5% in some studied cases, using the DenseNet121 network model, which is considered satisfactory results in the case studied compared to the performance of other models. As for the VGG16 model, it did not give any of the satisfactory results in this field, the accuracy of the classification did not exceed 55% in most cases, and in only two cases it reached about 60% and 62%. The model presented during the research - DenseNet121 model - can be used in the diagnostic process and help in obtaining accurate results in terms of diagnostic results. As for the VGG16 model, it does not give satisfactory results according to the results also obtained during the research, so it is excluded in this type of applications.

Highly Active Thermophilic L-Asparaginase from Melioribacter roseus Represents a Novel Large Group of Type II Bacterial L-Asparaginases from Chlorobi-Ignavibacteriae-Bacteroidetes Clade

L-asparaginase (L-ASNase) is a biotechnologically relevant enzyme for the pharmaceutical, biosensor and food industries. Efforts to discover new promising L-ASNases for different fields of biotechnology have turned this group of enzymes into a growing family with amazing diversity. Here, we report that thermophile Melioribacter roseus from Ignavibacteriae of the Bacteroidetes/Chlorobi group possesses two L-ASNases—bacterial type II (MrAII) and plant-type (MrAIII). The current study is focused on a novel L-ASNase MrAII that was expressed in Escherichia coli, purified and characterized. The enzyme is optimally active at 70 °C and pH 9.3, with a high L-asparaginase activity of 1530 U/mg and L-glutaminase activity ~19% of the activity compared with L-asparagine. The kinetic parameters KM and Vmax for the enzyme were 1.4 mM and 5573 µM/min, respectively. The change in MrAII activity was not significant in the presence of 10 mM Ni2+, Mg2+ or EDTA, but increased with the addition of Cu2+ and Ca2+ by 56% and 77%, respectively, and was completely inhibited by Zn2+, Fe3+ or urea solutions 2–8 M. MrAII displays differential cytotoxic activity: cancer cell lines K562, Jurkat, LnCap, and SCOV-3 were more sensitive to MrAII treatment, compared with normal cells. MrAII represents the first described enzyme of a large group of uncharacterized counterparts from the Chlorobi-Ignavibacteriae-Bacteroidetes clade.

Development of Goal Sensor in Futsal Goal Using Pattern Detection

Development of Goal Sensor Tools in Futsal Sports is a tool in matches and training to detect goals in futsal games. This tool can help teams, coaches and referees in detecting goals in matches and training. This tool was made with the aim of assisting the coach in applying the game system to defend and attack in order to get goals and so as not to concede. This tool serves to detect goals without any doubt in goal decision making.This study aims to develop a goal sensor to assist in matches and training. The population in this study were 30 athletes from the Joint Club FS and Tibor FC as well as 6 experts in each field. The form of the tool that has been made in advance is validated by 3 experts, namely 1 sports expert from the University who has a sports education background, 1 futsal coach expert and 1 electronics expert. The small group test involved 10 athletes and 3 experts, then the results were validated with an average value of the third validity of 77%. The results of the large group trial involved 20 people and 6 experts, then the results were validated with an average value of the sixth validity of 84%. Based on the results of validation by experts, it can be concluded that the development of a goal sensor in the futsal goal using 2020 pattern detection is valid and can be used. However, this tool cannot be disseminated because there are still many shortcomings in this tool.

Armorial Lockplates: A Story of Success in Renaissance Rome

This article was prompted by a gilt bronze lockplate in the Rijksmuseum, originally the decorative fastening of a chest and one of a large group of similar objects. Hardly any other metalwork design was more extensively reproduced in Italian Mannerism. Its success was based on the appealing design and the fact this type of lockplate offered the possibility of integrating coats of arms and thus personalizing a chest. The paper presents new examples not yet listed in Charles Avery’s comprehensive overview (2001), identifies a whole series of clients for these lockplates on the basis of heraldic and genealogical analyses and deduces from this an origin in Rome and a dating of the entire group (previously dated 1540) to the last third of the sixteenth century.It has been generally assumed that the specific function of these objects was to decorate marriage chests. Closer analysis argues against this thesis. The lockplate in the Rijksmuseum is particularly significant in this context. The coats of arms on its lateral cartouches identify the Roman Orazio Ruspoli and his wife Felice Cavalieri (marr. 1594) as the clients for the piece. Surprisingly, however, the crest on the hasp belongs to a family that was not related to this couple. A comparable finding is made for a lockplate in the National Gallery in Washington, which has also been misinterpreted so far. In this case, too, the coats of arms on the plate and on the hasp do not point to a family connection, but to neighbouring and presumably friendly families. The analysis of other examples, such as one in the Palazzo Venezia, confirms that these lockplates and the chests to which they were attached were not exclusively bound to the context of marriage. As travelling chests, which became must-have items for the Roman upper class, they seem to have been open to a variety of functions.

Die invloed van die lojaliteite en onderliggende vertaalfilosofie van die vertaler op die vertaalkeuses, met verwysing na die Afr2020 Bybelvertaling

The influence of the translator’s loyalties and underlying translation philosophy on the translation choices, with reference to the Afr2020 Bible translation. When the reader looks a little deeper than the initial superficial ‘Revised’ Old Translation impression that reading the Afrikaans 2020 translation gives you, then one realizes that a great deal of effort had to be put into leading such a large group of diverse translators to understand the essence of a direct translation and to be able to apply it consistently. But it is precisely here that problems can arise. Due to the nature of skopus and the style of the Afrikaans 2020 translation, this direct translation can be categorised on the side of the more literal translations and it thus has a very high percentage of agreement with the 1953 Old Afrikaans translation. If the direct translation is not just another name or a revision of the so-called word-for-word translation, then what is this direct translation? Van der Merwe referring to this translation also touches on this issue when he says: ‘a ‘direct’ translation of the Bible is not new jargon for a word-for-word translation of the Bible. It is an attempt to ‘interpretively resemble’ in good idiomatic Afrikaans all the communicative clues of the source text in the contexts construed for the source text audience’. This underlying fundamental premise brings a lot of tension to the fore. Van der Merwe also confirms this (2014:294) by stating: ‘attempts to translate ancient texts directly (is) an almost impossible ideal (to) pursue’.Contribution: This study evaluated the Afrikaans 2020 translation according to its own criteria, the translation brief and to its self-proclaimed nature as ‘direct’ translation in order to try to make an objective evaluation and assessment of this great work. This process also pointed out where the loyalties of the translators lie, and what the underlying translation philosophy is, and how difficult it is to make a distinction between the direct translation method and using archaic words and terms.
