Room temperature ferroelectric effect and enhanced dielectric permittivity in Rochelle salt/PVA percolative composite films

Jamal Uddin,T.R. Middya,B.K. Chaudhuri 한국물리학회 2013 Current Applied Physics Vol.13 No.3

Rochelle salt (RS) filled polyvinyl alcohol (PVA) composite films have been prepared via a simple solution casting technique. The transport, dielectric and ferroelectric properties of the samples have been studied. The dielectric permittivity decreases slowly with increasing frequency and rise gradually with increasing temperature and RS contents in the composites. As the volume fraction of the RS reaches to percolation threshold (fc w0.0538), an abrupt increase in the dielectric permittivity (w403 almost 80 times higher compared to pure PVA with low loss w0.18 at 1 kHz and room temperature) occurs in the RS/PVA composite film, which is attributed to the formation of the conductive network in the matrix. Ferroelectric loops up to room temperature (300 K) and the slight increase in Curie temperature from 297 to 300 K have also been observed for percolative composite film. The developed composite material with low loss high dielectric permittivity and room temperature ferroelectric behaviors might be applied in the technological fields.

Purpose: The Malaysia Education Blueprint is primarily concerned with the transformation of students' minds through the curriculum offered at the school level (2013-2025). Diversity in the application of teaching and learning methods is one means of achieving the transformation of students' minds through the Secondary School Standard Curriculum. Consequently, the production of ExSheetLink's Module for Accounting Education is the primary outcome of this study, which had three objectives: the need for ExSheetLink's Module in the process of producing financial statements for Accounting Students in secondary school to the Accounting Teacher; and the design of ExSheetLink's Module that meets the entire process in the production of financial statements for Accounting Students in secondary school based on the Documents Curriculum and the Accounting Students' needs. Research design, data and methodology: This study outlines the research framework for module development in accordance with the Design and Development Research Method, which combines multiple research techniques (Mixed Method). Results: The development of ExSheetLink’s Module is completed and can be used for the level of effectiveness purposes. Conclusion: The transformation of Accounting Students' minds is a success thanks to the ExSheetLink Module. Researchers also suggested that all Malaysian Secondary School accounting students test the ExSheetLink Module.

Saka and the Abject: Masculine Dominance, the Mother and Contemporary Malay Horror Films

Jamaluddin Bin AZIZ,Azlina Bt ASAARI 이화여자대학교 아시아여성학센터 2014 Asian Journal of Women's Studies(AJWS) Vol.10 No.1

Malay horror films have made a comeback since the government of Malaysia in 2004 gradually relaxed the ban. Since then, Malaysian cinema has been flooded with horror films, and this causes concern among politicians as they argue that horror films can impede the growth of the mind, as the values perpetuated by horror films are seen to go against the government’s effort to promote scientific and critical thinking among Malaysians. We argue that understanding the current view that consigns this film genre to the feminine side of the binary system, hence, the irrational as opposed to the rational or masculine, is one of the reasons for such concern. Employing Julia Kristeva’s concept of abjection in the tradition of feminist psychoanalysis as the theoretical framework, this paper looks at the mother character and her relationship with Saka in a contemporary Malay horror film to reveal the ideological work of such masculine ideology. Saka is a mystical figure that is “invited” into a family and is passed down through the matrilineal line from one generation to the next. We argue that even though Saka is used as an entrapment for female liberatory possibilities, it ironically mirrors the destabilization of masculine dominance. We do this by illustrating how female characters in the genre are typecast and Saka functions as a masculine substitute that reinforces this idea, which ultimately is used to investigate female sexuality; hence, playing the typical role of masculine ideological dominance.

Filem Seram telah muncul kembali setelah dilonggarkan syarat oleh kerajaan Malaysia pada tahun 2004. Sejak itu, terdapat kebanjiran filem seram, ini menjadikan satu fenomena yang merisaukan ahli politik yang membahaskan yang kebanjiran ini mampu membantutkan permikiran kerana nilai yang disampaikan oleh filem seram ini bercanggah dengan usaha kerajaan untuk mempromosi permikiran saintifik dan kritikal. Kami membahaskan bahawa dengan mencampakkan genre seram ini ke bahagian feminin dalam system binari, yakni yang tidak rasional berbanding sifat maskulin yang dikira rasional, adalah satu punca isu ini. Dengan menggunakan konsep abjection oleh Julia Kristeva dalam tradisi feminis psikoanalisis sebagai kerangka teori, makalah ini melihat kepada watak ibu dan hubungan beliau dengan Saka dalam satu filem seram kontemporari untuk merungkai ideologi maskulin yang terdapat dalam teks filem ini. Saka adalah satu kuasa yang diundang ke dalam sesuatu keluarga dan biasanya diturunkan melalui sebelah ibu. Kami membahaskan walaupun Saka digunakan sebagai satu perangkap kepada kemungkinan wanita untuk bebas, ia secara ironisnya mencerminkan ketidakstabilan dominasi maskulin. Kami membuktikan ini dengan menyatakan yang wanita dalam genre ini tidak progresif dan Saka berfungsi sebagai pengganti maskulin yang mengukuhkan dakwaan ini, yang akhirnya menyiasat seksualiti wanita. Hal ini menjadikan mereka alat memainkan maskulin yang dominan.

This study investigates the application of management information systems to the quality of local government financial reports, especially the principle of transparency and the law of accountability, which have been measures of financial statement performance evaluation. The study was conducted in Enrekang Regency, Indonesia, which, based on the results of the examination, the Supreme Audit Board reported the status of Disclaimer, Fair with Exceptions, and Fair without Exceptions for three years each. This study used a sample of 35 respondents, finance department employees who worked on local government financial reports. Descriptive quantitative data were collected using a questionnaire instrument, then with the assistance of the Program Solution and Product Statistics (SPSS) Program, data were processed to test hypotheses. The results showed that the use of management information systems based on information and communication technology (ICT) had a significant influence on the quality of local government financial reports. The findings of this study indicate that the application of ICT-based management information systems affects the accountability and transparency of local government financial reports. This finding is reinforced by the use of the principles of government agility in the form of government apparatuses that apply responsive dexterity, flexibility agility, and competency agility.

( Jamarosliza Jamaluddin ),이명천 ( Myung Cheon Lee ) 한국접착및계면학회 2017 접착 및 계면 Vol.18 No.3

본 연구에서는 포호필름 코팅 용도를 목적으로 silicone-urethaneacrylate (SUA) 올리고머를 포함하는 자외선 경화형 점착제를 제조하였으며 SUA올리고머의 양과 자외선조사량이 접착물성에 미치는 영향을 조사하였다. 그 결과, 올리고머의 양과 자외선조사량이 증가 할 수 록 박리강도는 감소하였으나 응집력은 증가하였다. 자외선 조사가 시작되면서 젤함량은 초기에 급속히 증가하였으나 이후 일정량을 유지하였다. 탈착시험 결과 70%의 올리고머 함량의 시편 S70이 다른 S50(올리고머 50%함량)과 S60(올리고머 60%함량)과 비교하여 가장 우수한 탈착성을 보였으며 탈착 후 기재에 아무런 잔사를 남기지 않았다. S70의 경우 1857 자외선 조사량과 2270 mJ/㎠ 에서 26mJ/㎡ 이하의 표면에너지를 보였으며 95% 이상의 광투과도를 보였으며 이러한 물성은 보호용 필름이 요구하는 물성에 적절하다. In this study, we made UV cured acrylic pressure sensitive adhesive containing silicone-urethaneacrylate (SUA) oligomer for a coating on protective film and investigated the effect of SUA oligomer content and UV-dose on adhesion properties. The results illustrated that peel strength decreases with increasing oligomer content and UV-dose, while holding power increases. The gel fractions sharply increased after UV irradiation and then remain constant with prolonged UV exposure. From peel-off test, sample S70 (70% oligomer content) shows the best peelability and removability without remaining any mark or adhesive material on the test substrate than S50 (50% oligomer content) and S60 (60% oligomer content). Sample S70 also showed a surface energy lower than 26mJ/㎡ and a transmittance higher than 95% at UV-dose 1857 and 2270 mJ/㎠ which met the required properties for protective film application.

Quantum Deep Unfolding Based Resource Allocation Optimization for Future Wireless Networks

Triwidyastuti Jamaluddin,나로타마 바스카라,신수용 한국통신학회 2023 韓國通信學會論文誌 Vol.48 No.8

This paper introduces Quantum Deep Unfolding (QDU), a technique for optimizing power allocation and transmit precoding in multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) systems. Solving the optimization problem in such systems poses a significant challenge due to its high computational complexity and non-convex nature, which increases the risk of being stuck at a local minimum. In order to address this issue, QDU leverages an iterative algorithm and analytical derivation to enhance the sum rate performance and training processes by optimizing power allocation and transmit precoding. The proposed approach integrates a Quantum Neural Network (QNN) induced by an iterative deep unfolding algorithm with a learning solution inspired by the training process. At each QDU layer, the iterative optimization involving the Projected Gradient Descent (PGD) operator is unfolded to learn the crucial parameters. The objective of QDU is to maximize the achievable sum rate while simultaneously reducing computational complexity.

Investigating the Missing "I" in Zubaidah... My Story : A Dialogic Consideration

AZIZ, Jamaluddin 이화여자대학교 아시아여성학센터 2011 Asian Journal of Women's Studies(AJWS) Vol.17 No.4

This paper starts with the question: What drives/motivates someone to write about his or her own life? This question is ubiquitous and has been one of the major concerns in the study of autobiographical writings. It has been argued that such writings, though personal, are seen as a way of liberating women from the shackle of male oppression. Autobiography allows women to have a voice, and to have it heard too. In effect, women find agency in their writing, allowing them to be and feel like subjects. The development of critical theory such as postmodernism further complicates the relationship between writing and female subjectivity as it foregrounds the irrevocable fragmentation of the subject. Employing Lynne Pearce’s feminist reading of Bakthin’s dialogics as theoretical framework, this paper suggests an alternative reading to Zubaidah... My Story, arguing that what critics of autobiography can do is to re-engage with and then re-evaluate the poetics of perception, foregrounding the urgency of reconstructing female reality. Hinging on my role as a reader, I argue that one way to re-engage and re-evaluate the constituents of the writer’s subjectivity is to dialogically approach the text as it is within this reconstruction that her story is elevated from mere historical account to culturally relevant communication of the female self.
