The Role of the Speech-Language Pathologist in the Schools for the Treatment of Voice Disorders: Working within the Framework of the Individuals with Disabilities Education Improvement Act

The role of the speech-language pathologist (SLP) has developed considerably over the past 20 years given the medical and technological advances in life-sustaining procedures. Children born with congenital, surgical, or medically fragile conditions become mainstreamed into regular school-based settings, thus extending the traditional role of the treating SLP and multidisciplinary team. Understanding the impact of associated voice disorders on educational performance requires dissemination of additional and important information, as eligibility decisions for students in school-based settings must be made within the framework of the federal legislation and regulations governing the provision of services for students with disabilities. This article discusses how to identify children with voice disorders under the Individuals with Disabilities Education Improvement Act (IDEA), the role of the SLP in various triaging scenarios, and how models of voice therapy can be integrated in a school-based setting

Light Ions Response of Silicon Carbide Detectors

Silicon carbide (SiC) Schottky diodes 21 mum thick with small surfaces and high N-dopant concentration have been used to detect alpha particles and low energy light ions. In particular 12C and 16O beams at incident energies between 5 and 18 MeV were used. The diode active-region depletion-thickness, the linearity of the response, energy resolution and signal rise-time were measured for different values of the applied reverse bias. Moreover the radiation damage on SiC diodes irradiated with 53 MeV 16O beam has been explored. The data show that SiC material is radiation harder than silicon but at least one order of magnitude less hard than epitaxial silicon diodes. An inversion in the signal was found at a fluence of 10^15 ions/cm^2.Comment: 20 pages, 16 figures, submitted for publication to Nuclear Instruments and Methods in Physics Research

Determinants of Adapted Behaviors on Employee and Entrepreneurs Against the Covid-19 Pandemic: Theory of Planned Behavior

New Normal is a change in behavior to continue carrying out normal activities but coupled with the implementation of health protocols to prevent Covid-19 transmission. In Indonesia itself, the new normal is applied as a realistic response from the Indonesian government to the existence of COVID-19 as well as the results of the analysis in various sectors of national life, especially the future of the national economy in the medium and long term. After the implementation of the new normal, it automatically affects the routine activities carried out by the community, especially those activities that were restricted by the government at the time of the New Normal. This study aims to analyze the factors that influence behavior change after the application of the New Normal in the Covid-19 Pandemic. A modified Theory of Planned Behavior is used in this study using testing through Structural Equation Modeling (SEM-PLS). A total of 427 respondents who have worked have answered the online questionnaire containing 61 questions. The results of this study indicate that knowledge and understanding of covid-19 make people understand the severity they feel and the vulnerabilities they may experience. The severity and vulnerability they feel also have an influence on their attitudes, behavior control, past behavior, and subjective norms so that they have a strong factor in building their intention to behave during the pandemic when the new normal is enacted. The intention that has been built with the support of attitudinal factors, past behavior, subjective norms, and behavior control also changes people's behavior. Employees are able to more moderate the relationship between attitudes towards intention and the relationship between past behavior and intention than entrepreneurs.New Normal pada masa pandemi Covid-19 berarti menerapkan protocol kesehatan pencegahan penyebaran virus Covid-19 sehingga dapat tetap melakukan aktivitas normal. Di Indonesia sendiri, normal baru ini diterapkan sebagai respon realistis dari pemerintah Indonesia terhadap keberadaan COVID-19 serta hasil analisis di berbagai sektor kehidupan bangsa, khususnya masa depan perekonomian nasional di tingkat menengah dan jangka panjang. Setelah diterapkannya Normal Baru, otomatis berdampak pada kegiatan rutin yang dilakukan oleh masyarakat, terutama kegiatan yang dibatasi oleh pemerintah pada saat Normal Baru. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi perubahan perilaku setelah penerapan New Normal pada Pandemi Covid-19. Teori Perilaku Berencana yang dimodifikasi digunakan dalam penelitian ini menggunakan pengujian melalui Structural Equation Modeling (SEM-PLS). Sebanyak 427 responden yang telah bekerja telah menjawab kuesioner online yang berisi 61 pertanyaan. Hasil penelitian ini menunjukkan bahwa pengetahuan dan pemahaman tentang COVID-19 membuat masyarakat memahami tingkat keparahan yang mereka rasakan dan kerentanan yang mungkin mereka alami. Keparahan dan kerentanan yang mereka rasakan juga berpengaruh pada sikap, pengendalian perilaku, perilaku masa lalu, dan norma subyektif mereka sehingga mereka memiliki faktor yang kuat dalam membangun niat mereka untuk berperilaku selama pandemi ketika normal baru diberlakukan. Niat yang dibangun dengan dukungan faktor sikap, perilaku masa lalu, norma subyektif, dan pengendalian perilaku turut mengubah perilaku masyarakat. Karyawan mampu lebih memoderasi hubungan antara sikap terhadap niat dan hubungan antara perilaku dimasa lalu dan niat daripada wirausahawan

Size Distribution and Growth of Young Payangka Fish, Ophieleotris Aporos (Bleeker) From Lake Tondano

The research was conducted at the location of Lake Tondano, Minahasa District.The young payangka fish, locally known as nike fish by fishermen of the area. This study aims to determine the size distribution, length-weight relationships and to know the captivity growth in the aquarium. The research is expected to be a source of information about the fish of young payangka (Nike) and be able to contribute on the efforts of nike fish management in Lake Tondano for the future. Sampling is done by using a triangular shaped trap (sibusibu) with a length of 4m, width of 1.30m (top), and a mesh size of 0.5mm. The length frequency distribution with the size mode appeared most during the first of observation was in the range of 13.5 to 15.4 class size and changed in size in the third week of the 19.5-21.4 class sizes. Later in the fifth week the mode is in the range of 15.5-17.4 class size and changes in size in the seventh week at the range of 23.5-25.4 class size. The length-weight relationship of the study was showed by allometric growth (b = 2.70; b <3) which means the length increases faster than weight gain. Absolute weight growth of 0.2532g was recorded and absolute length growth of 10.12mm for 12 weeks was observed as well. Growth of a relatively large weight gained with value of 0.067mg occurs between the seventh week and the eighth week

Quantifying Laryngopharyngeal Reflux in Singers: Perceptual and Objective Findings

This study examines the relationship between laryngopharyngeal reflux (LPR) symptoms and oropharyngeal pH levels in singers. We hypothesized that reported symptoms would correlate with objective measures of pH levels from the oropharynx, including the number and total duration of reflux episodes. Twenty professional/semiprofessional singers completed the Reflux Symptom Index (RSI) and underwent oropharyngeal pH monitoring. Mild, moderate, or severe pH exposure was recorded during oropharyngeal pH monitoring. Correlations were performed to examine potential relationships between reflux symptoms and duration of LPR episodes. Symptom severity did not correlate with pH levels; however, we found a number of covariances of interest. Large sample sizes are necessary to determine if true correlations exist. Our results suggest that singers may exhibit enhanced sensitivity to LPR and may therefore manifest symptoms, even in response to subtle changes in pH. This study emphasizes the importance of sensitive and objective measures of reflux severity as well as consideration of the cumulative time of reflux exposure in addition to the number of reflux episodes
