The Safeguarding of Intangible Cultural Heritage from the Perspective of Civic Participation: The Informal Education of Chinese Embroidery Handicrafts

Heritage education can enable social empowerment. Within the broader goal of social empowerment, a current challenge is to establish principles that promote social participation in traditional education. The practice of protecting intangible cultural heritage in China has developed its own unique working model based on the basic theoretical level of UNESCO. This research used cultural citizenship as a theoretical guide, focused on the traditional embroidery craftsmanship of China’s intangible cultural heritage, and conducted exploratory research on the learning intention and value influence indicators of citizens participating in intangible cultural heritage. The research design of this study was divided into two phases: the first phase was designed to collect evaluation indicators that affect the learning of intangible cultural heritage skills, and to support these data using semi-structured in-depth interviews. In the second phase, the convergence of the value indicators that affect the learning of intangible cultural heritage techniques was completed using questionnaire surveys and statistical analyses. Factor analysis was performed using SPSS software. SEM (structural equation modeling) confirmatory analysis was performed using Amos software. Through a two-stage hybrid study, a value recognition scale for the informal educational inheritance of intangible cultural heritage handicrafts was obtained within the local context of China. The scale contains four first-level indicators (ICH’s authenticity, cultural identity, performed value, and social recognition) and 17 second-level indicators. The research results were based on UNESCO’s education indicators for SDG 4, and put forward principles for practices aimed at protecting China’s intangible cultural heritage’s local informal education. Reflecting on the Chinese tradition of citizen participation in protecting intangible cultural heritage could provide references for the practice of intangible cultural heritage protection in other fields and regions. This is consistent with the UN’s SDG 4.7 (ensure all learners acquire knowledge and skills needed to promote sustainable development).
Optimize Task Scheduling and Resource Allocation Using Nature Inspired Algorithms in Cloud based BDA

Task Scheduling and Resource allocation is a prominent research topic in cloud computing. There are several objectives associated with Optimize Task Scheduling and Resource allocation as cloud computing systems are more complex than the traditional distributed system. There are several challenges like resolving the task mapped to the node on which task to be executed. A simplified but near optimal proposed nature inspired algorithms are focus in this paper. In this paper basic idea about optimization, reliability and complexity is considered while design a solution for modern BDA (Big Data Application). Detailed analysis of experimental results, it is shown that the proposed algorithm has better optimization effect on the fair share policies which are presently available in most of the BDA. In this paper we focused on Dragonfly algorithm and Sea lion algorithms which are nature inspired algorithms. These algorithms are efficient for optimization purpose for solving task scheduling and resource allocation problem. Finally performance of the hybrid DA algorithm and Sea lion is compared with traditional techniques used for modern BDA using Hadoop MapReduce. Simulation results prove the efficacy of the suggested algorithms.
Ultrahigh Sensitive Wearable Pressure Sensors Based on Reduced Graphene Oxide/Polypyrrole Foam for Sign Language Translation

Pressure sensors have attracted worldwide attention due to their extensive application requirements in wearable devices, flexible touch display, soft robotics, and health monitoring. Although many pressure sensors have been developed, it still remains a grand challenge to achieve ultrahigh sensitivity with good stability in low‐pressure regions. Herein, the polypyrrole (PPy) is introduced to reduced graphene oxide foam (rGOF) via in situ solventless polymerization to manufacture rGO/PPyF, which significantly enhances the sensitivity and stability of the derived sensors. The as‐fabricated sensor demonstrates an ultrahigh sensitivity of 32.32 kPa−1 in the pressure region of 0–21 Pa, high resolution, and excellent cycling stability. Furthermore, the pressure sensor can transform different hand gestures to distinguishable electrical signals in sign language translation, which indicates that the pressure sensor has a bright application prospect in wearable devices and human–computer interaction.
Evaluation of Psychometric Properties and Differential Item Functioning of the Dental Anxiety Inventory (DAI-36) Questionnaire using Iterative Hybrid Ordinal Logistic Regression

Background: Dental anxiety is a major dental problem. The difference of dental anxiety between groups may be reflect of the perception of individual of the items of questionnaire at the same level of the underlying dental anxiety. The propose of this study was to assess whether the Dental Anxiety Inventory (DAI-36) showed differential item functioning (DIF) by gender, age and education levels.Methods: By an iterative hybrid ordinal logistic regression model, we assessed measurement equivalence of DAI-36 items across gender, education, and age groups. All analysis was run by lordif package in R3.1. 3 software for 950 participants.Results: The chi-square statistics declared 7, 7, and 4 non-uniform DIF items, and 2, 5, and 4 uniform DIF items across gender, education, and age groups, respectively. ΔR2 was always lower than 0.07 in all uniform and non-uniform DIF items. However, Δβ1 revealed significant uniform DIF in items 1 and 8 across gender ( Δβ1(item 1)=0.0137, Δβ1(item 8)=0.0124) and items 22 and 27 across age categories ( Δβ1(item 22)=0.0110, Δβ1(item 27)=0.0136). Conclusions: DIF items had no large magnitude or cancel out each other, so statements phrased in DAI-36 questionnaire have equivalent meaning across respondents, regardless of their gender, education, and age groups.
Research on Default Rate of Financing Projects of Online Lending Platform Based on XGBoost Model

In recent years, with the rapid development of the online credit industry and the wide application of big data technology, using an integrated learning model to evaluate loan risk quickly and accurately has been a concern by academics and practitioners. In order to predict the default rate of the financing projects of the online loan platform with high accuracy and efficiency, this paper adopts the XGBoost model based on the importance of certain features to process loan application data of an online loan platform and establishes the default rate prediction model of online loan projects. Ten years' loan application data of American online lending platforms were selected to verify the model, and the prediction results were compared with those of Random Forest (RF) and LightGBM. The results show that the XGBoost model based on the optimization derivation and the second-order Taylor expansion has higher accuracy in the evaluation.
Spatial distribution of heavy metal and risk indices of water and sediments in the Kunhar River and its tributaries

Abstract The present study investigated heavy metal (HM) concentrations in water and sediment of the Kunhar River and its tributaries in Kaghan valley, Northern Pakistan. The highest mean concentration was observed for iron (Fe) 316 ± 47.4 µg/L and the lowest for cadmium (Cd) 2.45 ± 0.31 µg/L in the upstream water of this study. The highest mean hazard quotient value of 0.43 was calculated for children through downstream water consumption. The concentration of HM in water was used for the calculation of HM pollution index and HM evaluation index , showing a low level of contamination. The highest mean sediment concentration was found for Fe was 35500 ± 2700 mg/L and the lowest for Cd was 1.96 ± 0.23 mg/L in upstream of Kunhar River. Pollution quantification factors values were the highest downstream. Statistical analyses revealed that water and sediment contamination of Kunhar River and its tributaries was mainly attributed to geogenic sources.
State-of-the-Art Circuit Techniques for Low-Jitter Phase-Locked Loops: Advanced Performance Benchmark FOM Based on an Extensive Survey

A conventional figure-of-merit for a phase-locked loop (PLL) based on integrated RMS jitter and power consumption has been a strong indicator to compare and to normalize PLL performance over different designs. However, it has some limitations because any impact from reference clock is not reflected. As a result, it is not enough to evaluate state-of-the- art PLL designs such as injection-locked PLL, clock-multiplying delay-locked loop, and sub-sampling PLL where PLL circuit noise is effectively suppressed so the reference clock contributes more on PLL jitter performance. This paper discusses alternative figure-of-merits capturing the reference clock impacts based on an extensive survey of state-of-the-art PLL designs, and also validates them with the survey.
Processes driving understory community dynamics in Ulleungdo Island broadleaved forest, South Korea

The development stage of forest trees has considerable impact on the understory plant species; however, little research has been dedicated to in-depth investigation of the changes in the ecological processes (deterministic and stochastic) over a mid-term observational period ( ≥ 10 years). We analyzed the forest floor environment, including bare mineral soil, tree communities (den-sity and biomass), understory plant species composition, diversity, cover, and changes in co-occurring species in the Albongbunji Basin on Ulleungdo Island over an 11-year period (2009 – 2019). The forest floor environment exhibited a broad spectrum of changes, beginning in the middle of the observation period and after heavy rainfall, and heavy sediment deposition events were observed. The overstory tree density showed patterns of a general increase and subsequent decline, and the overstory tree biomass increased and then remained steady. The heavy rainfall and sediment deposition as disturbance events also coincided with changes in species composition and the turnover rate of the understory plant communities, causing changes in major ecological processes. The general pattern of species co-occurrence (zeta diversity) was fitted to an exponential model, indicating the dominance of stochastic processes. The results show a shift in relative importance from deterministic to stochastic processes in the successional stages of understory plant community assembly over a mid-term observational period.
Experimental Evaluation of Procedures to Quantify Carbohydrate Carbon in Some Calcareous Soils

ABSTRACT Carbohydrates are an important component of soil organic matter, and a method is needed to quantify them, which would be efficient in terms of time and cost. Different extractants and methods were examined in this work for their efficiency to extract carbohydrate C from four calcareous soils. Four extractants (distilled water, 0.5 M potassium sulfate (K2SO4), and 0.25 and 0.5 M sulfuric acid (H2SO4)) and three incubation methods (shaking for 16 h, heating in an oven (85 °C) for 16 h, and heating in a water bath (85 °C) for 2.5 h) were compared. The results show that significantly more carbohydrate C was extracted from all four soils with oven and water bath heating of the soil–extractant suspensions than with shaking them at room temperature. The efficiency of the extractants decreased in this order: 0.5 M H2SO4 > 0.25 M H2SO4 > 0.5 M K2SO4. The combination of the heated–water bath incubation method with 0.5 M H2SO4 as extractant was the most efficient method.
Classification of the four‐class motor imagery signals using continuous wavelet transform filter bank‐based two‐dimensional images

The feature extraction technique plays a vital role in obtaining better classification accuracy. In this paper, a novel framework is proposed, which develops two‐dimensional (2D) images for convolutional neural network (CNN) to classify four (left hand, right hand, feet, and tongue) MI tasks. 2D image is formed by decomposing each trial using continuous wavelet transform (CWT) filter bank after pre‐processing the MI‐based EEG data by multi‐class common spatial pattern (CSP) method. Obtained images are used to train the CNN model for classification. The proposed framework is evaluated using publicly available BCI competition IV dataset 2a by calculating the classification accuracy for all subjects. Results show that the proposed framework has been giving better classification accuracy than some existing CNN‐based and conventional machine learning‐based approaches compared in this paper. The average time required to train CNN using the proposed framework is 12.67 s, acceptable for online MI‐based BCI applications.
The Early Development of the Vaccinia–Rabies Recombinant Vaccine Raboral®

The recombinant vaccinia–rabies vaccine, now known as Raboral®, has been widely used in Europe and North America to control/eliminate rabies in the principal wildlife vectors, and thus prevent human transmission. The origins of this vaccine are sometimes forgotten, although the formulation has not changed substantially in almost four decades. This groundbreaking vaccine was assembled by a team at a very young (at that time) genetic engineering company, Transgène, in Strasbourg, France. The joint leaders of the rabies vaccine team reflect, 36 years later, on the trials and tribulations that went hand in hand with the construction of the vaccine.
Numerical Buckling Analysis of Hybrid Honeycomb Cores for Advanced Helmholtz Resonator Liners

In order to realize novel acoustic liners, honeycomb core structures specially adapted to these applications are required. For this purpose, various design concepts were developed to create a hybrid cell core by combining flexible wall areas based on thermoplastic elastomer films and rigid honeycomb areas made of fiber-reinforced thermoplastics. Within the scope of the presented study, a numerical approach was introduced to analyze the global compressive failure of the hybrid composite core structure, considering local buckling and composite failure according to Puck and Cuntze. Therefore, different geometrical configurations of fiber-reinforced tapes were compared with respect to their deformation as well as their resulting failure behavior by means of a finite element analysis. The resulting compression strength obtained by a linear buckling analysis agrees largely with calculated strengths of the more elaborate application of the failure criteria according to Puck and Cuntze, which were implemented in the framework of a nonlinear buckling analysis. The findings of this study serve as a starting point for the realization of the manufacturing concept, for the design of experimental tests of hybrid composite honeycomb core structures, and for further numerical investigations considering manufacturing as well as material specific aspects.
Analysis of Earth Pressure Variation for Partial Displacement of Retaining Wall

Parts of the retaining wall might produce displacement under different load conditions. The moveable wall could impact the adjacent fixed wall, mainly reflecting on the variation of earth pressure and formation of the soil arching effect. This paper conducted the horizontal trap-door test to explore the variation of active earth pressure caused by partial displacement of the retaining wall. Different trap-door width and three displacement modes were addressed as the influence factors. The results indicated that the horizontal soil arching effect was generated after the active displacement of the trap-door and the soil pressure was redistributed. The distribution of lateral soil pressure was approximately an “inverted bell” curve. For trap-door widths of 20 cm, 30 cm, and 40 cm, a secondary soil arching effect appeared in the test. The relationship between lateral earth pressure and displacement was different with the traditional limited theory due to the influence of the soil arching effect. The variation curve of earth pressure corresponding to displacement could be divided into three stages. In addition, the distribution of earth pressure along the trap-door height was non-linear. Trap-door width can significantly influence the maximum earth pressure on the fixed wall and the range where pressure changes. Finally, the effect of load sharing was explored and found to be related with displacement and width of trap-door as well as the displacement mode.
Parental Factors as Determinants of Conduct Disorder among In-School Adolescents in Ibadan Metropolis, Nigeria

This study was carried out to observe the link between parental factors and Conduct Disorder (CD) among Nigerian school adolescents. A cross-sectional survey research design was adopted for the study where multi-stage sampling techniques led to selecting 1006 participants (mean age = 15.4 years) from six secondary schools in Ibadan, Oyo State, Southwestern Nigeria. Participants responded to Socioeconomic Status (SES) scale, the Parenting Styles Scale (PSS) and Frequency of Delinquent Behaviour Scaling Instrument (FDBSI). A high prevalence of CD was observed. We also observed that parenting styles significantly influenced conduct disorders. Responsive parenting is not a significant predictor of CD, while control parenting significantly predicted CD. Parental occupation significantly influenced CD, with formal occupation types having higher mean scores for both fathers and mothers. Finally, there was a significant influence of socioeconomic status on conduct disorder among the participants. Findings concluded that there is a high prevalence of conduct disorder. Authoritarian and uninvolved parents with formal occupation and families with higher socioeconomic status were conduct disorder determinants among adolescents.
Beyond place-based: the role of virtual communities via social media in young adult recovery

In post-disaster recovery, optimising psychosocial support is important for all groups of the population, yet young adults have tended to be overlooked as a demographic in their own right. Research was conducted to seek the perspectives of young adults through the narrative of their experiences in the years following the 2009 Gippsland bushfires. One emergent theme in the findings highlighted the importance of information and communication during and after events. Participants in this research sought information and support via social media and virtual communities. These sites traverse localised, place-based solutions, enabling young people to communicate over large geographical areas. The platforms aid dynamic and rapidly evolving support by sharing information, feelings and ideas. This research also highlighted the need to identify the gaps in information processes and support systems for young adults and to ensure youth-specific information is included in formal communications. Possible solutions are outlined taking into consideration the perspectives offered by the study participants.
Conceptual Study of Transesterification of Vegetable Oils in the Continuous-Stirred-Tank Reactor at Unsteady-State and Isothermal Conditions

The continuous-stirred-tank reactor (CSTR) is favorable for bi-phasic enzymatic reaction due to ease of operation, cost-effective and low downtime. Lack of study on the enzymatic reaction in the CSTR has disfavor this type of reactor compared to batch and packed bed. Presently, a simulation was carried out to simulate the behavior of the lipase-catalyzed production of biodiesel by using CSTR at isothermal conditions. The mathematical model incorporated the effect of the kinetic, thermal, and operating parameters. The parameters such as Michaelis constant (Km), inhibition constant (Ki), Gibbs inactivation energy (DelG) and mol flow rate are among determining factors of the course of the reaction. It is suggested that the enzyme with lower , higher , and higher should be chosen for the reaction. In continuous operation in the CSTR, the volumetric flow rate of the substrates and the initial concentration of the feed could be used to control reaction performance as these parameters will determine the total mol or ratio of the substrates in the reactor. Most, importantly, the longer residence time is preferred to achieve higher conversion, however, the volumetric flow rate must not be too low to prevent underperformance of reaction.
ON THE THERMODYNAMICS OF FATTY ACID OXIDATION

The energy yield from the combustion of fatty acids and the ATP yield of their oxidation increases with the length of the acyl chain and decreases with unsaturation. Simple expressions describing these relationships are compared with data from the literature, and expressions for the yield of ATP and reducing equivalents are given. From these we derive the corresponding expressions for the oxidation of triacylglycerol. These expressions are used to estimate the energy yields from the oxidation of selected fats and oils of known composition.
Complications Following Non-Surgical Aesthetic Treatments in HIV+ Patients Receiving Antiretroviral Therapy: A 12-Years Experience

Since the advent of HIV antiretroviral therapies at the end of the 20th century, the morbidity and mortality rates associated with HIV infection have decreased dramatically. Unfortunately, these benefits are associated with substantial morphologic changes in the body, such as abnormal fat distribution with peripheral lipohypertrophy and facial lipoatrophy. Facial wasting is considered the major stigma for HIV–infected people and may result in reduced antiretroviral adherence. Patients suffering from the stigmata of HIV infection can benefit from non-surgical aesthetic treatments performed with fillers or lipolytic agents that provide a quick and reliable service for facial rejuvenation, with high patient satisfaction and a low risk of complications. In the present paper, a retrospective analysis of complications following non-surgical aesthetic treatments (calcium hydroxyapatite-based filler, hyaluronic acid filler, polyacrylamide hydrogel filler and dehoxycholic acid injections), in a cohort of 116 consecutive HIV+ patients, treated over a period of 12 years, was performed. With the exception of the tardive swelling reported after calcium hydroxyapatite injections, complications were recorded just after polyacrylamide hydrogel treatment as small, palpable, nonvisible nodules or aseptic abscess. Our experience is consistent with those already published in the literature and the complication rate seems to be comparable to non-infected patients.
