Lily, Lily,Yadav, K.L.,Prasad, K. Techno-Press 2013 Advances in materials research Vol.2 No.1
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.

Childcare policies and services in Hong Kong after the handover: Beyond a feminist critique
Lily L. L. Xia,Joyce L. C. Ma 한국사회복지학회 2019 Asian Social Work and Policy Review Vol.13 No.3
This article reviews the development of childcare policies and services in Hong Kong after the handover, gauging it with two standards: promoting the equal development of children and gender equality in our society. Statistics derived from data taken from multiple sources show that the government has been sticking to a “positive non-in-tervention approach” to welfare development and that the male breadwinner/female carer model prevalent in this region was shaped and strengthened by current child-care policies and services. The current provision of childcare services is insufficient to guarantee the equal use of childcare among children of different socioeconomic backgrounds, or to ease the tension between the needs of childcare and job require-ments in a family, or to emancipate married women from the domestic sphere. A “generative welfare approach” that collects fiscal resources and redistributes them strategically with a systemic mind-set has been suggested for social policy and ser-vice planning, including spending the money in the right place, launching smart and practical policies that can achieve both pragmatic effects and ideological improve-ment in the area of gender equality, providing financial support or subsidies to a company for the provision of parental leave, and increasing the provision of quality childcare services.

Qualia and Ontology: Language, Semiotics, and Materiality; an Introduction
Lily Chumley 한국외국어대학교 HK 세미오시스 연구센터 2017 Signs and Society Vol.5 No.-
Qualia—sensory experiences of abstract qualities such as heat, texture, color, sound, stink, hardness, and so on—focus attention on prototypically “material” entities. But how is the ontological category of materiality constituted by conventional qualities, or qualisigns? For instance, how does the sound made by knuckles knocking on a table come to be an exemplary experience of, and a conventional sign for, “materiality”? What ontologies might undermine the seeming naturalness of this category, and to what effect? This issue contributes to the growing literature on semiotic approaches to materiality by arguing that attention to qualia, as sensorial and somatic experiences mediated by cultural qualisigns of value (Munn 1986), offers a useful analytic approach to the dialectics of matter (substrate, affordance) and nonmatter (idea, concept, category). The articles in this issue describe how modes of being and becoming are represented in and organized by discourses on qualia and demonstrate the crucial role of qualia and qualisigns in “ontological politics” (Mol 1999).

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.

We have developed magnetically controllable gold nanoparticles by synthesizing superparamagnetic Fe3O4 core/gold shell nanoparticles. The core/shell particles have the capability of forming gold 1D chains in the presence of an external magnetic field. Here we demonstrate dynamic and reversible self-assembly of the gold 1D chain structures in an aqueous solution without any templates or physical or chemical attachment. The spatial configuration of gold chains can be arbitrarily manipulated by controlling the direction of a magnetic field. This technique can provide arbitrary manipulation of gold 1D chains for fabrication purpose. To demonstrate this capability, we present a technique for immobilization of the gold particle chains on a glass substrate.

Are Banked Cloze Items Sensitive to Discourse Level Constraints?
Lily Guo 한국영어평가학회 2009 영어평가 Vol.3 No.1
The paper reports two studies which investigate whether banked cloze procedures reflect test-takers’ discourse level comprehension processes. In Study One, two banked cloze tests were administrated to 165 second-year students in a Chinese university. They were randomly divided into two groups. Half of them took the normal test where the sentences were in their original order and the other half completed the scrambled test where the sentences were rearranged. Study Two involved 141 second-year students in the same Chinese university and the same research procedures were applied. One of the main differences between the two studies lied in the cloze texts: the passage for the first study was a loosely ordered encyclopedic description while the text for the second was a chronological narration. T-test analysis between subjects’ scores in normal and scrambled conditions revealed that the normal cloze in Study One were not sensitive to sentence scrambling while that in Study Two were. The paper concludes that there may be considerable variation in the effectiveness of banked cloze in assessing discourse level abilities. Tester intervention is necessary for developing sound banked cloze tests.

Real-Data Comparison of Data Mining Methods in Prediction of Diabetes in Iran
Lily Tapak,Hossein Mahjub,Omid Hamidi,Jalal Poorolajal 대한의료정보학회 2013 Healthcare Informatics Research Vol.19 No.3
Objectives: Diabetes is one of the most common non-communicable diseases in developing countries. Early screening and diagnosis play an important role in effective prevention strategies. This study compared two traditional classification methods (logistic regression and Fisher linear discriminant analysis) and four machine-learning classifiers (neural networks, support vector machines, fuzzy c-mean, and random forests) to classify persons with and without diabetes. Methods: The data set used in this study included 6,500 subjects from the Iranian national non-communicable diseases risk factors surveillance obtained through a cross-sectional survey. The obtained sample was based on cluster sampling of the Iran population which was conducted in 2005–2009 to assess the prevalence of major non-communicable disease risk factors. Ten risk factors that are commonly associated with diabetes were selected to compare the performance of six classifiers in terms of sensitivity, specificity, total accuracy, and area under the receiver operating characteristic (ROC) curve criteria. Results: Support vector machines showed the highest total accuracy (0.986) as well as area under the ROC (0.979). Also, this method showed high specificity (1.000) and sensitivity (0.820). All other methods produced total accuracy of more than 85%, but for all methods, the sensitivity values were very low (less than 0.350). Conclusions: The results of this study indicate that, in terms of sensitivity, specificity, and overall classification accuracy, the support vector machine model ranks first among all the classifiers tested in the prediction of diabetes. Therefore, this approach is a promising classifier for predicting diabetes, and it should be further investigated for the prediction of other diseases.

Prevalence and Risk Factors of Functional Gastrointestinal Disorders in Infants in Indonesia
Lily Arsanti Lestari,Adhyatma Noor Rizal,Wahyu Damayanti,Yulianti Wibowo,Chang Ming,Yvan Vandenplas 대한소아소화기영양학회 2023 Pediatric gastroenterology, hepatology & nutrition Vol.26 No.1
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.
