The Use of Alphabet Flash Cards Learning Media in the Process of Learning While Playing at the Community Learning Activity Center in North Sulawesi Province

The development of the out-of-school education sector has a strategic role in improving the quality of human resources. In order to increase motivation and learning achievement of citizens learning to read, learning media is needed in the form of alphabet cards that are used by learning resources to develop learning models while playing for learning citizens. The purpose of this research is to: 1) design alphabet card learning media in the application of the development of the learning process, 2) applying the development of the learning process, and 3) finding the effectiveness of the implementation of the development of the learning process of reading while playing through the learning media of alphabet cards for citizens learning literacy in PKBM, North Sulawesi Province. This study has used the ”research and development” method, following the stages of ADDIE model development research (analyze, design, develop, implement, and evaluate) in 4 districts: 1) South Bolaang Mongondow, 2) East Bolaang Mongondow, 3) Talaud Islands, and 4) North Minahasa. This research is designed for 2 years and the first year, 2022, has been carried out in 3 stages, namely: 1) analyze stage, 2) design stage, and 3) development stage. Meanwhile, for the second year, there will be 2 stages, the implementation stage and the evaluation stage. It was concluded that: 1) prototype product design of Alphabet Card Learning Media can be understood and mastered by learning citizens; 2) the application of the development of the learning process is carried out through stages: (1) Recruitment of tutors, learning residents, and forming study groups; (2) Conducting training of trainers (TOT) for tutors; and (3) trials development; 3. The learning process is effective because: (1) The learning residents who were formerly literate but forgot their letters have re-learned them. (2) An improvement in the cognitive abilities of learning citizens; (3) A better ability to put letters together to form meaningful words; (4). Citizens who are learning become more involved. It is suggested that: 1) The teacher must develop an adaptable lesson plan; 2) The following aspects require revision: (1) the physical card alphabet’s size in both height and width; (2). For the sake of IPR and patent rights, a unique logo is required. 3). At the implementation and evaluation stage, this study must be continued.

Drosophila olfactory receptors as classifiers for volatiles from disparate real world applications

Olfactory receptors evolved to provide animals with ecologically and behaviourally relevant information. The resulting extreme sensitivity and discrimination has proven useful to humans, who have therefore co-opted some animals' sense of smell. One aim of machine olfaction research is to replace the use of animal noses and one avenue of such research aims to incorporate olfactory receptors into artificial noses. Here, we investigate how well the olfactory receptors of the fruit fly, Drosophila melanogaster, perform in classifying volatile odourants that they would not normally encounter. We collected a large number of in vivo recordings from individual Drosophila olfactory receptor neurons in response to an ecologically relevant set of 36 chemicals related to wine ('wine set') and an ecologically irrelevant set of 35 chemicals related to chemical hazards ('industrial set'), each chemical at a single concentration. Resampled response sets were used to classify the chemicals against all others within each set, using a standard linear support vector machine classifier and a wrapper approach. Drosophila receptors appear highly capable of distinguishing chemicals that they have not evolved to process. In contrast to previous work with metal oxide sensors, Drosophila receptors achieved the best recognition accuracy if the outputs of all 20 receptor types were used

III-V-on-silicon anti-colliding pulse-type mode-locked laser

An anti-colliding pulse-type III–V-on-silicon passively mode-locked laser is presented for the first time based on a III–V-on-silicon distributed Bragg reflector as outcoupling mirror implemented partially underneath the III–V saturable absorber. Passive mode-locking at 4.83 GHz repetition rate generating 3 ps pulses is demonstrated. The generated fundamental RF tone shows a 1.7 kHz 3 dB linewidth. Over 9 mW waveguide coupled output power is demonstrated

Accent attribution in speakers with Foreign Accent Syndrome

Purpose: The main aim of this experiment was to establish the extent to which the impression of foreignness in speakers with Foreign Accent Syndrome (FAS) is in any way comparable to the impression of foreignness in speakers with a real foreign accent. Method: Three groups of listeners attributed accents to conversational speech samples of 5 FAS speakers which were embedded amongst those of 5 speakers with a real foreign accent and 5 native speaker controls. The listener groups differed in their familiarity with foreign accented speech and speech pathology. Results: The findings indicate that listeners’ perceptual reactions to the three groups of speakers are essentially different at all levels of analysis. The native speaker controls are unequivocally considered as native speakers of Dutch while the speakers with a real foreign accent are very reliably assessed as non-native speakers. The speakers with Foreign Accent Syndrome, however, are in some sense perceived as foreign and in some sense as native by listeners, but not as foreign as speakers with a real foreign accent nor as native as real native speakers. This result may be accounted for in terms of the trigger support model of foreign accent perception. Conclusions: The findings of the experiment is consistent with the idea that the very nature of the foreign accent in different in both groups of speakers, although it cannot be fully excluded that the perceived foreignness in the two groups is one of degree
