BACKGROUND

As global obesity prevalence continues to increase, there is a need for accessible and affordable weight management interventions, such as web-based programs.

OBJECTIVE

This paper aims to assess the outcomes of healthy weight coaching (HWC), a web-based obesity management program integrated into standard Finnish clinical care.

METHODS

HWC is an ongoing, structured digital 12-month program based on acceptance and commitment therapy. It includes weekly training sessions focused on lifestyle, general health, and psychological factors. Participants received remote one-on-one support from a personal coach. In this real-life, single-arm, prospective cohort study, we examined the total weight loss, weight loss profiles, and variables associated with weight loss success and program retention in 1189 adults (963 women) with a BMI >25 kg/m² among participants of the program between October 2016 and March 2019. Absolute (kg) and relative (%) weight loss from the baseline were the primary outcomes. We also examined the weight loss profiles, clustered based on the dynamic time-warping distance, and the possible variables associated with greater weight loss success and program retention. We compared different groups using the Mann-Whitney test or Kruskal-Wallis test for continuous variables and the chi-squared test for categorical variables. We analyzed changes in medication using the McNemar test.

RESULTS

Among those having reached the 12-month time point (n=173), the mean weight loss was 4.6% (SE 0.5%), with 43% (n=75) achieving clinically relevant weight loss (≥5%). Baseline BMI ≥40 kg/m² was associated with a greater weight loss than a lower BMI (mean 6.6%, SE 0.9%, vs mean 3.2%, SE 0.6%; P=.02). In addition, more frequent weight reporting was associated with greater weight loss. No significant differences in weight loss were observed according to sex, age, baseline disease, or medication use. The total dropout rate was 29.1%. Dropouts were slightly younger than continuers (47.2, SE 0.6 years vs 49.2, SE 0.4 years; P=.01) and reported their weight less frequently (3.0, SE 0.1 entries per month vs 3.3, SE 0.1 entries per month; P<.001).

CONCLUSIONS

A comprehensive web-based program such as HWC is a potential addition to the repertoire of obesity management in a clinical setting. Heavier patients lost more weight, but weight loss success was otherwise independent of baseline characteristics.

Published: March 2022

In a video call there are several components, such as IP phone or softphone, CODEC, and server. Selection of softphone and CODEC is a consideration in building a video communication network because it will affect the quality of video call. This research compare the quality of video calls based on softphone application and CODEC combination. The quality measured by QoS, PSNR, and MOS parameters.Softphone applications examined in this research are Blink, Zoiper, MicroSIP, PortGo, Linphone, and X-Lite. CODEC examined in this research are H.264, VP8, H.263+, and H.263. Each softphone application will be combined with a CODEC that is native to the softphone. There are nine combinations of softphone application and CODEC.Based on the research results, CODEC H.264 has the best performance when paired with the Blink softphone application. CODEC VP8 has the best performance when paired with the Zoiper softphone application. The H.263+ CODEC has the best performance when paired with the PortGo softphone application. The H.263 CODEC and X-Lite softphone applications have the worst test results but still get “good” grades when tested using QoS, PSNR, and MOS parameters.

Published: March 2022

Sunspot is an area on photosphere layer which is dark-colored. Sunspot is very important to be researched because sunspot is affected by sunspot numbers, which present the level of solar activity. This research was conducted to make prediction on sunspot numbers using Gated Recurrent Unit (GRU) algorithm. The work principle of GRU is similar to Long short-term Memory (LSTM) method: the information from the previous memory is processed through two gates, that is update gate and reset gate, then the output generated will be input for the next process. The purpose of predicting sunspot numbers was to find out the information of sunspot numbers in the future, so that if there is a significant increase in sunspot numbers, it can inform other physical consequences that may be caused. The data used was the data of monthly sunspot numbers obtained from SILSO website. The data division and parameters used were based on the results of the trials resulted in the smallest MAPE value. The smallest MAPE value obtained from the prediction was 7.171% with 70% training data, 30% testing data, 150 hidden layer, 32 batch size, 100 learning rate drop.

Published: March 2022

Hate speech develops along with the rapid development of social media. Hate speech is often issued due to a lack of public awareness of the difference between criticism and statements that might contribute to this crime. Therefore, it is very important to do early detection of sentences that will be written before causing a criminal act due to public ignorance. In this paper, we use the advancement of deep neural networks to predict whether a sentence contains a hate speech and abusive tone. We demonstrate the robustness of different word and contextual embedding to represent the semantic of hate speech words. In addition, we use a document embedding representation via a recurrent neural networks with gated recurrent unit as the main architecture to provide richer representation. Compared to syntactic representation of the previous approach, the contextual embedding in our model proved to give a significant boost on the performance by a significant margin.

Authors: Nugroho Nicolaus Euclides Wahyu , Harjoko Agus
Published: March 2022

Hiragana and katakana handwritten characters are often used when writing words in Japanese. Japanese itself is often used by native Japanese as well as people learning Japanese around the world. Hiragana and katakana characters themselves are difficult to learn because many characters are similar to one another. In this study, hiragana and basic katakana, dakuten, handakuten, and youon were used, which were taken from the respondents using a questionnaire. This study used the CNN method which will be compared with a combination of the CNN and SVM methods which have been designed to identify each character that has been prepared. Preprocessing of character images uses the methods of image resizing, grayscaling, binarization, dilation, and erosion. The preprocessed results will be input for CNN as a feature extraction tool and SVM as a tool for character recognition. The results of this study obtained accuracy with the following parameters: 69×69 image size, 3 patience values, val_loss monitor callbacks, Nadam optimization function, 0.001 learning rate value, 30 epochs value, and SVM RBF kernel. If using a system that only uses the CNN network, the accuracy is 87.82%. The results obtained when using a combination of CNN and SVM were 88.21%.

Published: March 2022

SARA is a sensitive issue based on sentiments about self-identity regarding ancestry, religion, nationality or ethnicity. The impact of the issue of SARA is conflict between groups that leads to hatred and division. SARA issues are widely spread through social media, especially Twitter. To overcome the problem of SARA, it is necessary to develop an effective method to filter negative SARA. This study aims to analyze Indonesian-language tweets and determine whether the tweet contains positive or negative SARA or does not contain SARA (neutral). Machine learning (i.e., SVM) and lexicon-based method (i.e., LIWC) were compared based on 450 tweet data to determine the best approach for each sentiment (positive, negative, and neutral). The best evaluation results are shown in the negative SARA classification using SVM with λ = 3 and γ = 0.1, where Precision = 0.9, Recall = 0.6, and F1-Score = 0.72. The best results from the positive SARA classification were shown in the LIWC method, where Precision = 0.6, Recall = 0.8, and F1-Score = 0.69. The best evaluation results for neutral classification are shown in SVM with λ = 3 and γ = 0.1, with Precision = 0.52, Recall = 0.87, and F1-Score = 0.65.

COVID-19 prevention procedures are executed to support public services and business continuity in a pandemic situation. Manual mask use monitoring is not efficient as it requires resources to monitor people at all times. Therefore, this task can be supported by automated surveillance systems based on Deep Learning. We performed mask detection and face recognition for a real-environment dataset. YOLOV3 as a one-stage detector was implemented to simultaneously generate a bounding box of the face area and class prediction. In face recognition, we compared the performance of three pre-trained models, namely ResNet152V2, InceptionV3, and Xception. The mask detection showed promising results with MAP=0.8960 on training and MAP=0.8957 on validation. We chose the Xception model for face recognition because it has equal quality as ResNet152V2 but has fewer parameters. Xception achieved a minimal loss value in the validation of 0.09157 with perfect accuracy on facial images larger than 100 pixels. Overall the system delivers promising results and can identify faces, even those behind the mask.

Published: March 2022

Abstract: The environment-friendly renewable sustainable energy source is the need of time to promote and propagate to meet the growing power demand. More than 65% of India's electricity is generated by thermal power plants and 85% of the country's thermal power generation is coal-based. Our coal and gas reserves are limited and can last only for another 20-30 years. India is having enough hydropower potential i.e. to a tune of 148 GW (which would be able to meet a demand of 84 GW at 60% load factor) but as of date, its contribution is only 12.2% out of our total demand. Though the initial cost of hydro projects is comparatively high but the maintenance cost is minimal. To initiate a project Detailed Project Report (DPR) is required to be prepared. Since huge investment is involved in the hydroelectric project, hence, exhaustive techno-economic examining is required to decide for investing. Covering all the aspects of investigation enables the apprising agencies to examine the report holistically and provide clearances in a minimal time frame. In the scope of construction materials survey and geotechnical investigation, the availability and suitability of construction materials are to be assessed. The geotechnical investigation provides design parameters to the designer. Keywords: detailed project report, construction materials survey, rock, soil, concrete, rockfill.

Modern life and rapid development require women to take over in developing work careers, and even some become leaders of organizations and countries. In contrast to past perceptions that place women are considered low and tend to experience discrimination in careers and jobs. The participation of women by working brings negative consequences resulting from role conflicts. This study aims to provide empirical evidence regarding the effect of multiple role conflict on the performance of female employees with job stress as a mediating variable. The sample in this study was 97 employees of Bank Jateng, the Coordinator in Purwokerto. The data analysis method uses the structural equation modeling - partial least square (SEM-PLS) with SmartPLS version 3.3.2 software. The results showed that multiple role conflicts had no effect on performance, and job stress had no effect on performance. Multiple role conflicts have a positive influence on job stress. In addition, the moderating role of job stress shows a connecting effect between the influence of multiple role conflicts on the performance of female employees

Published: March 2022

Many teachers seem interested in their classes being more student-centered. Students making more choices about their own learning forms a key aspect of student-centered learning, as well as life-long learning. This article offers ideas for ways to provide students with more choices in their learning and suggests ways to encourage students to make choices when given opportunities to do so. These ideas for increasing student choice include extensive reading, cooperative learning, multiple intelligences, service learning, thinking questions, and use of the internet and other IT affordances. Student choice fits with an overall paradigm shift toward democratizing society, and it also fits with greater choice for teachers. Theoretical underpinnings of student choice include social cognitivism, social constructivism, humanistic psychology, self-directed learning, and social interdependence theory.

Authors: Avcı Halim , Çalışkan Zafer
Published: March 2022

Until the Augmented Neo-Classical Growth Model developed by Mankiw, Romer and Weil, growth theories have ignored the human capital factor. This study aims to investigate the impact of health on economic growth in Turkey between 1960-2014 through a production function that includes human capital. Health and education are included in the production function as the two main components of human capital. The Multivariate Auto-Regressive Distributed Lag (ARDL) Bounds Test was conducted for empirical analysis. As a result, a significant long-term cointegration relationship was found between the variables. The results also indicate that a 1% increase in life expectancy at birth leads to a 0.67% increase in GDP, a 1% increase in the number of students per teacher in vocational and technical secondary education leads to a 0.21% decrease in GDP, and a 1% increase in the number of students per teacher in tertiary education leads to a 0.21% increase in GDP.
Are Referred-To Auditors Associated with Lower Audit Quality and Efficiency?
Authors: Krishnan Jayanthi , Li Mengtian
Published: March 2022

Inadequate supervision by lead auditors of “other” (component) auditors contributing to audit engagements has been a recent regulatory concern. However, uniquely in the United States, the lead auditor is required to conduct only minimal supervision of the other auditor and refer to the other auditor in its audit report, when it divides responsibility with the latter. Our sample of “referred-to” (RT) firm-years is divided, about equally, between audits of consolidated subsidiaries and equity-method investees. We document two findings. First, supervision challenges drive the use of RT auditors for consolidated subsidiaries while the component’s materiality drives the use of RT auditors in both settings. Second, there is some evidence that RT auditors in both settings are associated with lower audit quality and efficiency compared with control samples, and this negative effect is stronger for consolidated subsidiaries. Our research is relevant to the Public Company Accounting Oversight Board’s proposed changes in auditing standards for other auditors.

Varying Impact of Gestational Diabetes Mellitus on Incidence of Childhood Cancers: An Age-Stratified Retrospective Cohort Study
Authors: Marcoux Sophie , Côté-Corriveau Gabriel , Healy-Profitós Jessica , Auger Nathalie
Published: March 2022

OBJECTIVE

We studied the association between gestational diabetes mellitus and early versus late childhood cancer.

RESEARCH DESIGN AND METHODS

We conducted a retrospective cohort study of 1 million children born between 2006 and 2019 in Quebec, Canada. We identified children who were exposed to gestational diabetes mellitus in utero and followed them from birth up to 14 years of age to identify new-onset cancers. We estimated hazard ratios (HRs) for the association between gestational diabetes mellitus and childhood cancer using Cox proportional regression models with adjustment for covariates through inverse propensity score weights.

RESULTS

A total of 83,626 children (8.2%) were exposed to gestational diabetes mellitus, and 1,702 developed cancer during 7.6 million person-years of follow-up. Children exposed to gestational diabetes mellitus had a higher risk of any cancer (HR 1.19, 95% CI 1.01–1.40), with signals present for blood cancer (HR 1.27, 95% CI 0.92–1.76) and solid tumors (HR 1.14, 95% CI 0.94–1.40). The association between gestational diabetes mellitus and cancer was strongest early in life and decreased with age. Gestational diabetes mellitus was associated with 1.47 times the risk of any cancer (95% CI 1.21–1.79), 1.44 times the risk of solid cancer (95% CI 1.12–1.87), and 1.61 times the risk of blood cancer (95% CI 1.09–2.36) in children age <2 years. Gestational diabetes mellitus was not significantly associated with blood or solid cancers after 2 years of age, and all associations disappeared after 6 years.

CONCLUSIONS

Hyperglycemia may be carcinogenic in utero and may be a novel risk factor for early childhood cancer.
Acquisition of Self-Care Responsibility in Youth With Type 1 Diabetes: Opportunities for Improving Tailored Diabetes Education and Support Programs
Authors: La Banca Rebecca Ortiz , Volkening Lisa K. , Laffel Lori M.
Published: March 2022

Background

There is gradual acquisition of type 1 diabetes self-care responsibility across childhood as youth mature and gain more independence from their family. Understanding the timing of diabetes self-care by youth can guide the tailoring of diabetes education and support programs.

Objective

To investigate parent-perceived responsibility for diabetes self-care tasks across childhood.

Methods

Parents/guardians of youth (ages 5–18 years) with type 1 diabetes reported parent involvement in diabetes management using the Diabetes Family Responsibility Questionnaire. Survey items were divided items into five domains: nutrition, monitoring, insulin dosing, communication, and health surveillance. Age-groups for analyses were 5–10 years (elementary school), 11–14 years (early adolescence), and 15–18 years (late adolescence). Demographic, diabetes management, and A1C data were collected at the time of survey completion.

Results

Youth (n = 148, 50% male) were a mean age of 12.9 ± 3.3 years, with a mean type 1 diabetes duration of 6.2 ± 3.6 years; 66% used insulin pump therapy, and the mean A1C was 8.4 ± 1.3%. Of the parents (84% mothers, 91% White), 83% were married, and 52% were college educated. Per parent report, less parental involvement was associated with older youth age (P <0.001). Across all age-groups, more overall parental involvement was related to lower A1C (P = 0.02). Youth self-care in the nutrition domain began in elementary school, whereas self-care in monitoring and insulin dosing began in early adolescence, and self-care with regard to communication started in late adolescence. Responsibility for health surveillance remained mainly under parent care throughout childhood and adolescence.

Conclusion

Providing education and support for youth during their acquisition of self-care tasks, especially those relating to nutrition, monitoring, and insulin dosing, may help to prevent glycemic deterioration later in childhood and adolescence.
