Lead-free compound $(Na_{0.5}Bi_{0.5})(Zr_{0.75}Ti_{0.25})O_3$ was prepared using conventional ceramic technique at $1070^{\circ}C$/4h in air atmosphere. X-ray diffraction analysis showed the formation of single-phase orthorhombic structure. Permittivity data showed low temperature coefficient of capacitance ($T_{CC}{\approx}5%$) up to $100^{\circ}C$. Complex impedance studies indicated the presence of grain boundary effect, non-Debye type dielectric relaxation and evidences of a negative temperature coefficient of resistance. The ac conductivity data were used to evaluate the density of states at Fermi level and apparent activation energy of the compound.
HHT method for system identification and damage detection: an experimental study
Lily L. Zhou,Gang Yan 국제구조공학회 2006 Smart Structures and Systems, An International Jou Vol.2 No.2
Recently, the Hilbert-Huang transform (HHT) has gained considerable attention as a novel technique of signal processing, which shows promise for the system identification and damage detection of structures. This study investigates the effectiveness and accuracy of the HHT method for the system identification and damage detection of structures through a series of experiments. A multi-degree-of-freedom (MDOF) structural model has been constructed with modular members, and the columns of the model can be replaced or removed to simulate damages at different locations with different severities. The measured response data of the structure due to an impulse loading is first decomposed into modal responses using the empirical mode decomposition (EMD) approach with a band-pass filter technique. Then, the Hilbert transform is subsequently applied to each modal response to obtain the instantaneous amplitude and phase angle time histories. A linear least-square fit procedure is used to identify the natural frequencies and damping ratios from the instantaneous amplitude and phase angle for each modal response. When the responses at all degrees of freedom are measured, the mode shape and the physical mass, damping and stiffness matrices of the structure can be determined. Based on a comparison of the stiffness of each story unit prior to and after the damage, the damage locations and severities can be identified. Experimental results demonstrate that the HHT method yields quite accurate results for engineering applications, providing a promising tool for structural health monitoring.

Transition from school-to-work is important for people with disabilities because they have shown a pattern of overwhelming low expectations and are particularly vulnerable to unemployment. How effective are the students with disabilities prepared for school-to-work transition is not yet evaluated in Singapore. Results of the inquiry would add to the body of knowledge on transition planning and aid transition planners to make progress towards transition services. The purpose of this study was to identify the success factors in increasing the employability outcomes and barriers faced in implementing school-to-work transition for students with mild intellectual disability in two schools from the Association for Persons with Special Needs. The schools, a secondary and a post-secondary school, were selected as they were successful in providing transition services for students aged 16 to 21 years. Using the mixed methods research paradigm, data were collected for the study. The views of 16 employers, 16 parents and 84 students who were involved in the transition planning were sought. The findings of the study recommended an integrated approach to transition planning comprising four key elements: prevocational and vocational training, transition assessment and counseling, homeschool-community partnership and work experiences. The study also provided grounds to advocate for a competency-based training model in advancing life-long planning for individuals with mild intellectual disability to prepare them for employment.
USING VIDEO MODELING TO SUPPORT COMMUNICATION INTENTS FOR AN ADOLESCENT WITH AUTISM

Individuals with autism tend to be devalued because of the Triad of Impairment in which impairment of social communication is one. A lack of understanding regarding the subtle aspects of social communication and interaction can make it difficult for individuals with autism to make friends or get and keep a job. This three-month case study design aims to explore how video modeling can improve communication intents. The subject is a 19- year-old female with autism and mild intellectual disability. The subject uses non-conventional ways to communicate requests and protests. The communication needs and abilities matrix is used to establish the profile of the subject. The social interaction and communication pattern of the subject is analyzed through classroom observation, video record and interviewing of the parents and teachers. Using video modeling, the subject demonstrated the ability to communicate intents of request and protest successfully across two functional settings. Given the preference of individuals with autism for visual stimuli and avoidance of face-to-face attention, video-based instruction is promising in increasing social and adaptive skills. It is hope of this study to inspire and generate interest in teachers and parents to use video modeling to instruct lifelong planning for quality living and societal integration for individuals with autism.

Purpose: Information regarding functional gastrointestinal disorders (FGIDs) in infants is currently lacking in Indonesia. This study aimed to describe the prevalence and risk factors of FGIDs in infants aged 6 weeks to 4 months in Indonesia. Methods: This cross-sectional study of 433 infants was conducted between September 2018 and February 2020. Information on FGIDs was collected using the Infant Gastrointestinal Symptom Questionnaire and the Feeding Practice and Gut Comfort Questionnaire. Adapted Rome IV criteria were used to define the FGIDs. Results: The prevalence of regurgitation was 26.3%; 16.8% of the infants presented cryingrelated symptoms and 5.5% exhibited constipation. The statistical analyses revealed that constipation was associated with sex (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.07-7.71; p=0.043), employment of the father (OR, 0.3; 95% CI, 0.12-0.77; p=0.01), and education of the mother (OR, 1.92; 95% CI, 1.07-3.51; p=0.031). Length at birth (OR, 0.74; 95% CI, 0.55-0.99; p=0.042) was associated with constipation. Length at visit (OR, 0.83; 95% CI, 0.76-0.91; p<0.001) was associated with regurgitation, and the weight at visit (OR, 0.58; 95% CI, 0.35-0.96; p=0.038) was associated with crying and/or colic. A history of parental FGIDs was associated with crying-related symptoms (OR, 2.12; 95% CI, 1.23-3.68; p=0.007). Conclusion: Regurgitation, crying, and constipation are common FGIDs in infants. Some parental and infant characteristics may be predictors for FGIDs. Further investigations are needed to evaluate the clinical relevance of our findings. Understanding the determinants of FGIDs will benefit healthcare professionals and parents to improve infant’s quality of life and better manage these condition.
Equity, Diversity and Inclusion of Persons with Disabilities in Singapore

The paper constitutes the report of the progress and resources Singapore has made available, specifically in how people with disabilities have been integrated into the community. The report is a significant milestone which shows the collaborative efforts among the various stakeholders in making Singapore a more inclusive society and resulting in the third five-year Enabling Master Plan (2017 – 2021). Building on the first and second Enabling Masterplans in 2007 and in 2012 respectively, the recommendations and proposed strategies highlighted in the third Enabling Masterplan are endorsed by a 22-member Steering Committee comprising the collaborative efforts of public and private sectors as well as persons with disabilities and their caregivers. The Committee envisions Singapore to be a caring and inclusive society where persons with disabilities are empowered to achieve their fullest potential and participate fully as integral and contributing members of society. Good progress are made in the area of early intervention, education, employment, mobility and accessibility to community-based rehabilitation and integration services as well as supporting the use of assistive technology for work, play and improving the quality of life for persons with disabilities. Today, there are more support services and assistance available to for persons with disabilities and their caregivers towards empowering persons with disabilities to fulfil their aspirations and realise their potential. More opportunities are also created among us to create opportunities for interaction at school, work and within the community for persons with disabilities.
