Abstract Although certain speech development milestones are readily observable, the developmental course of speech motor control is largely unknown. However, recent advances in facial motion tracking systems have been used to investigate articulator movements in children and the findings from these studies are being used to further our understanding of the physiologic basis of typical and disordered speech development. Physiologic work has revealed that the emergence of speech is highly dependent on the lack of flexibility in the early oromotor system. It also has been determined that the progression of speech motor development is non-linear, a finding that has motivated researchers to investigate how variables such as oromotor control, cognition, and linguistic factors affect speech development in the form of catalysts and constraints. Physiologic data are also being used to determine if non-speech oromotor behaviors play a role in the development of speech. This improved understanding of the physiology underlying speech, as well as the factors influencing its progression, helps inform our understanding of speech motor control in children with disordered speech and provide a framework for theory-driven therapeutic approaches to treatment.

<p>A manganese substituted Anderson type polyoxometalate, [MnMo<sub>6</sub>O<sub>24</sub>]<sup>9-</sup>, tethered with an anthracene photosensitizer was prepared and used as catalyst for CO<sub>2</sub> reduction. The polyoxometalate-photosensitizer hybrid complex, obtained by covalent attachment of the sensitizer to only one face of the planar polyoxometalate, was characterized by NMR, IR and mass spectroscopy. Cyclic voltammetry measurements show a catalytic response for the reduction of carbon dioxide, thereby suggesting catalysis at the manganese site on the open face of the polyoxometalate. Controlled potentiometric electrolysis showed the reduction of CO<sub>2</sub> to CO with a TOF of ~15 sec<sup>-1</sup>. Further photochemical reactions showed that the polyoxometalate-anthracene hybrid complex was active for the reduction of CO<sub>2</sub> to yield formic acid and/or CO in varying amounts dependent on the reducing agent used. Control experiments showed that the attachment of the photosensitizer to [MnMo<sub>6</sub>O<sub>24</sub>]<sup>9-</sup> is necessary for photocatalysis.</p><div><br></div>

The deprotonation of S2B17H17 with sodium hydride and subsequent reaction with [PtCl2(PMe2Ph)2] gives the new macropolyhedral metallathiaborane [(PMe2Ph)2PtS2B16H16], of which the cluster consists of a conventional eleven-vertex nido {SB10} unit, fused, with two boron atoms in common, with a {PtSB8} unit of unique ten-vertex neo-arachno constitution and geometry. The latter geometry suggests a configuration for the previously structurally uncharacterised [B10H15]- anion; starting from this configuration, DFT calculations of structure and thence of boron nuclear shieldings, which are found very closely to mimic those found experimentally, thence support a fluxional structure for [B10H15]- with three {BHB(bridging)} and two {BH(endo)} hydrogen atoms around a six-membered open face.

During the COVID-19 pandemic, schools did not open face-to-face learning services. The Ministry of Education and Culture has issued a policy learning from Home (BDR) to support the principles of the Education Policy in the COVID-19 Pandemic that the health and safety of students, educators, education personnel, families, and the community is the top priority. However, learning in Vocational School (SMK) is mostly based on practice so that BDR activities cannot be implemented. One thing that is done to overcome this is that some practicum activities can be executed using multimedia known as virtual laboratories. The aim of this study is to conduct a need analysis for the development of a virtual laboratory.  Needs analysis is carried out to gather data about gaps and needs as well profiles of students that can be used as a basis or reference in developing virtual laboratory at the next stage. Data collection was carried out by means of observation, interviews, and distributing questionnaires. The results showed that a virtual laboratory was needed to support practical learning for vocational students.

Abstract: Helmet can reduce head trauma as well as maxillofacial trauma due to motorcycle accident. This study was aimed to prove the effect of helmet and its type in reducing craniofacial injury. Any intracranial abnormalities were evaluated with the CT Marshall scoring system and maxillofacial abnormalities were evaluated with FISS. This was an analytical comparative study with a cross sectional design. The results showed that there were 72 patients with craniofacial trauma; 59 patients with intracranial abnormalities and 24 patients with maxillofacial abnormalities. There were 43.1% patients that wore helmet; 31.9% of them wore open-face helmet. Data were analyzed by using the unpaired t-tests. Based on FISS, the effect of helmet on maxillofacial injury obtained a t-value of 0.787 (P = 0.217) which indicated that there was no difference in FISS scores between patients wearing helmet and not. Based on the CT Marshall scoring system, the effect of helmet on the intracranial injury obtained a t-value of 1.822 (P = 0.036) which indicated that there was a difference in scores between patients wearing helmet and not. This meant that wearing helmets had some influence on the occurence of head injuries. Based on FISS, the impacts of full-face helmet and open-face helmet on maxillofacial injuries obtained a t-value of 1.890 (P = 0.034) which indicated that there was a difference in FISS between the two types of helmets. Based on the CT Marshall scoring system, the impacts of full-face helmet and open-face helmet on intracranial injuries obtained a t-value of 1.714 (P = 0.049) which indicated that there was a difference in CT Marshall scores between the two types of helmets. Conclusion: Helmet and its type, full-face and open-face, had some influence on the occurence of either maxillofacial or intracranial injuries.Keywords: craniofacial injury, motorcycle, helmetAbstrak: Penggunaan helm dapat mengurangi kejadian trauma kepala dan trauma maksiofasial akibat kecelakaan sepeda motor. Penelitian ini bertujuan untuk membuktikan bahwa pemakaian helm dan tipe helm berperan dalam menurunkan cedera kraniofasial. Abnormalitas intrakranial dievaluasi dengan skoring CT Marshall dan abnormalitas maksilofasial dievaluasi dengan FISS. Jenis penelitian ialah analitik komparatif dengan desain potong lintang. Hasil penelitian mendapatkan 72 pasien dengan trauma kraniofasial; 59 pasien dengan abnormalitas intrakranial dan 24 pasien dengan abnormalitas maksilofasial. Terdapat 43,1% pasien yang menggunakan helm; 31,9% menggunakan helm open-face. Data dianalisis menggyunakan uji t tidak berpasangan. Berdasarkan FISS, efek helm terhadap cedera maksilofasial mendapatkan t = 0,787 (P = 0,217) yag menunjukkan tidak terdapat perbedaan skor antara pasien yang menggunakan dan tidak menggunakan helm. Berdasarkan skoring CT Marshall, efek helm terhadap cedera intrakranial mendapatkan t = 1,822 (P = 0,036) yang menunjukkan terdapat perbedaan skor antara pasien yang menggunakan dan tidak menggunakan helm. Hal ini memperlihatkan bahwa penggunaan helm berpengaruh terhadap kejadian cedera kepala. Berdasarkan FISS, dampak jenis helm full-face dan open-face terhadap cedera maksilofasial mendapatkan t = 1,890 (P = 0,034) yang menyatakan terdapat perbedaan skor FISS antara pengggunaan kedua jenis helm. Berdasarkan skoring CT Marshall, dampak helm full-face dan open-face terhadap cedera intrakranial mendapatkan t = 1,714 (P = 0,049) yang menunjukkan terdapat perbedaan skor CT Marshall antara penggunaan kedua jenis helm. Simpulan: Penggunaan helm dan jenis helm (full-face dan open-face) memengaruhi terjadinya cedera maksilofasial dan intrakranial.Kata kunci: cedera kraniofasial, sepeda motor, helm
