Authors: Nabilah Anisah , Sigit Riyanto , Fariza Arna , Madyono Madyono
Published: March 2023

Bone age is an index used by pediatric radiology and endocrinology departments worldwide to define skeletal maturity for medical and non-medical purposes. In general, the clinical method for bone age assessment (BAA) is based on examining the visual ossification of individual bones in the left hand and then comparing it with a standard radiographic atlas of the hand. However, this method is highly dependent on the experience and conditions of the forensic expert. This paper proposes a new approach to age estimation of human bone based on the carpal bones in the hand and using a residual network architecture. The classification layer was modified with batch normalization to optimize the training process. Before carrying out the training process, we performed an image augmentation technique to make the dataset more varied. The following augmentation techniques were used: resizing; random affine transformation; horizontal flipping; adjusting brightness, contrast, saturation, and hue; and image inversion. The output is the classification of bone age in the range of 1 to 19 years. The results obtained when using a VGG16 model were an MAE value of 5.19 and an R2 value of 0.56 while using the newly developed ResNeXt50(32x4d) model produced an MAE value of 4.75 and an R2 value of 0.63. The research results indicate that the proposed modification of the residual training model improved classification compared to using the VGG16 model, as indicated by an MAE value of 4.75 and an R2 value of 0.63.

Published: March 2023

Most of the health data contained unbalanced data that affected the performance of the classification method. Unbalanced data causes the classification method to classify the majority data more and ignore the minority class. One of the health data that has unbalanced data is Pima Indian Diabetes. Diabetes is a deadly disease caused by the body's inability to produce enough insulin. Complications of diabetes can cause heart attacks and strokes. Early diagnosis of diabetes is needed to minimize the occurrence of more severe complications. In the diabetes dataset used, there is an imbalanced data between positive and negative diabetes classes. Diabetes negative class data (500 data) is more than diabetes positive class (268), so it can affect the performance of the classification method. Therefore, this study aims to apply the Smote-Tomeklink and Random Forest methods in the classification of diabetes. The research methodology used is the collection of diabetes data obtained from Kaggle, as many as 768 data with eight input attributes and 1 output attribute as a class, pre-processing data is used to balance the dataset with Smote-Tomeklink, classification using the random forest method, and performance evaluation based on accuracy, sensitivity, precision, and F1-score. Based on the tests conducted by dividing data using 10-fold cross-validation, the Random Forest algorithm with Smote-TomekLink gets the highest accuracy, sensitivity, precision, and F1-score compared to Random Forest with Smote. The Random Forest algorithm with Smote-Tomeklink has 86.4% accuracy, 88.2% sensitivity, 82.3% precision, and 85.1% F1-score. Thus, using Smote-Tomeklink can improve the performance of the random forest method based on accuracy, sensitivity, precision, and F1-score.

Published: March 2023

One of the agricultural products which is an important aspect of the life of Indonesian people is rice. Rice disease has a devastating effect on rice production, while detecting rice diseases in real-time is still difficult. Therefore, this study designed a Livestream video system that is equipped with a rice disease Classification system. The Livestream system utilizes 4G network communication and is assisted by the WebSocket protocol to communicate in real-time and for the rice disease Classification system using YOLO algorithm. In addition, Livestream uses the raspberry pi camera V2 to take video stream data. In analyzing the performance of the Livestream system, four tests were carried out, namely: functionality test, connectivity test, classification performance test, and implementation performance test. The test was carried out using the wireshark and conky tools, while the classification training used 5447 images from the Huy Minh do dataset that he provided on the Kaggle website. The results show that all programs run well and get a good QoS value according to the index of the parameter results, it is also found that sending non-base64 can reduce the size of the data to approximately 200,000 bytes/s and the performance of the classification system is good because it has an average accuracy of 80% even though it is quite burdening the raspberry pi. This system can still be optimized and developed further to support research in the field of data transmission and the performance of machine learning in a microcontroller.

Published: March 2023

As the fourth industrial revolution guides humanity toward the next stage of civilization, there have been various changes across multiple domains of life. The youngest generations now face a new era in which unexpected problems continuously arise and evolve. Consequently, innovation is needed, especially in psychology and technology. This innovation is important because of the increasing number of issues that plague human life, especially psychological problems, trauma, and phobias. However, modern psychology has not kept pace with these developments. Based on this, the researchers developed a tool called IP-Light Technologies. This tool was developed using a research and development approach. Product testing in the form of prototypes is limited and widely carried out in West Nusa Tenggara, West Sumatra, DKI Jakarta, and Bali. As a result of testing, the final prototype was widely produced. The perceptual light prototype comprises a set of lamps and a multiplicity of LED lights extending in horizontal wings spaced concerning the main handle; an elongated handle extending from the main handle in the opposite direction, vertically to horizontally; a linear array of illuminated displays located on the display surface of the handle; and numerous control switches mounted on the casing. The device further comprises a power supply, and control circuit wherein the LEDs on both wings are arranged in an array configured so that the combination of each bulb may project high-intensity light. A lamp clip with a spring design can be clipped on the edge of a table or any other surface.

Published: March 2023

Signature genuine verifications of offline hand-written signatures are critical for preventing forgery and fraud. With the growth of protecting personal identity and preventing fraud, the demand for an automatic system for signature verification is high. The signature verification system is then studied by many researchers using various methods, especially deep learning-based methods. Hence, deep learning has a problem. Deep learning requires much training time for the data to obtain the best model accuracy result. Therefore, this paper proposed a CNN Batch Normalization, the CNN architectural adaptation model with a normalization batch number added, to obtain a CNN model optimization with high accuracy and less training time for offline hand-written signature verification. We compare CNN with our proposed model in the experiments. The research method in this study is data collection, pre-processing, and testing using our private signature dataset (collected by capturing signature images using a smartphone), which becomes the difficulties of our study because of the different lighting, media, and pen used to sign. Experiment results show that our model ranks first, with a training accuracy of 88.89%, an accuracy validation of 75.93%, and a testing accuracy of 84.84%â€”also, the result of 2638.63 s for the training time consumed with CPU usage. The model evaluation results show that our model has a smaller EER value; 2.583, with FAR = 0.333 and FRR = 4.833. Although the results of our proposed model are better than basic CNN, it is still low and overfitted. It has to be enhanced by better pre-processing steps using another augmentation method required to improve dataset quality.Â

Published: March 2023

Today, academic institution involves digital data to support the educational process. It has advantages, especially related to ease of access and process. However, security problems appear related to digital data. There were several information security incidents in the academic environment. In order to mitigate the problem, metrics identification is required to determine the risk of incidents. There are many risks model and metrics to estimate the risk, such as DREAD, OWASP, CVSS, etc. However, specific metrics are required to obtain appropriate risk values. Therefore, this study aims to define metrics for an academic institution. The proposed metrics are obtained from The Family Educational Rights and Privacy Act (FERPA) regulation. It consists of directory information, educational information, personally identifiable information, and risk of information leakage. In order to achieve the objective, this study involves survey and reliability analysis to result in output. The survey is conducted by involving 90 respondents with various levels of education and jobs. The Cronbach's alpha and Test-retest are methods to determine this study's reliability. According to reliability analysis, the Cronbach's alpha method results in coefficients for the metrics between 0.730 - 0.911, while the Test-retest method results in coefficients between 0.630 - 0.797. These coefficients have a reliable category, so the proposed metrics are adequate for determining risk of information security incidents in academic environments. The reliable metrics will be developed as variables of the risk assessment model for the academic environment in the future study.Â

Published: March 2023

The development of transportation technology is increasing every day; it impacts the number of transportation and their users. The increase positively impacts the economy's growth but also has a negative impact, such as accidents and crime on the highway. In 2018, the number of accidents in Indonesia reached 109,215 cases, with a death rate of 29,472 people, which was mostly caused by the late treatment of the casualties. On the other hand, in the same year, there were 8,423 mugs, and 90,757 snitches cases in Indonesia, with only 23.99% of cases reported. This low reporting rate is mostly caused by the lack of awareness and knowledge about where to report. Therefore, a quick response surveillance system is needed. In this study, an audio-based accident and crime detection system was built using a neural network. To improve the system's robustness, we enhance our dataset by mixing it with certain noises which likely to occur on the road. The system was tested with several parameters of segment duration, bandpass filter cut-off frequency, feature extraction, architecture, and threshold values to obtain optimal accuracy and performance. Based on the test, the best accuracy was obtained by convolutional neural network architecture using 200ms segment duration, 0.5 overlap ratio, 100Hz and 12000Hz as bandpass cut-off frequency, and a threshold value of 0.9. By using mentioned parameters, our system gives 93.337% accuracy. In the future, we hope to implement this system in a real environment.

Frontier in the Far East: George H. Kerr’s historical narrative of the Ryukyu Islands
Authors: Sensui Hidekazu
Published: March 2023

George H. Kerr (1911–1992) is an American historian who authored Ryukyu: Kingdom and Province before 1945 (Kerr 1953a), the sole general history of theislands in English; he was also a Taiwan specialist in the military and government whose book won him the reputation as the ‘father of Taiwanese independence’ (Lu 2006). He rearranged fragmented memory and recorded it in such a way as to justify a separate people, the Ryukyuans or the Taiwanese, from the nation-state to which they may belong—Japan or China—so that the United States could strategically exploit their home islands. While mainly focusing on Kerr in the Ryukyus and unveiling the process of his writing, this paper offers a bridge to Kerr in Taiwan and addresses the question of a common interpretive framework underneath his historical narratives.

Making Ordinary People Actors in National History
Authors: Bodemer Margaret
Published: March 2023

This paper analyzes a recent exhibit in Vietnam’s national ethnology museum which depicted ordinary people’s everyday experiences during the postwar, pre-reform era in Hanoi, an era which was full of hardship and had rarely been  discussed publicly prior to this. The exhibit narrated a critical yet nostalgic representation which favored the experiences of ‘ordinary citizens’’ above official discourses about this period. I argue that the exhibit designers aimed to pose ordinary citizens as significant actors in national history, thereby narrating Vietnam’s modern history in a new way. In the course of critically examiningthe past and the present, the exhibit pushed the boundaries of social criticism and public discourse, and showed that museum exhibits are not neutral spacesfor the production of knowledge but, rather, can become sites which mediate indirect negotiation between people and the state and re-interpret the past forthe present and the future.

В работе представлены результаты оптимизации лабораторного метода определения действующего вещества лекарственных препаратов L-аспарагиназы. Установлено, что метод позволяет количественно измерять активность L-аспарагиназы в сыворотке крови пациентов в диапазоне 19,531 – 1250 единиц активности фермента/л при построении единой калибровочной кривой для высоких (более 78,125 ед/л) и низких значений активности фермента (19,531 – 78,125 ед/л), что приводит к значительному ускорению процесса анализа при сохранении точности измерений. Валидация соответствия измерений между модифицированным и оригинальным методом, осуществленная путем сравнительного анализа калибровочных кривых, построенных в условиях соответствующих протоколов, показала сопоставимость точности количественного определения. Полученные результаты могут быть с успехом применены при проведении лекарственного мониторинга в онкологической и онкогематологической практике.

The order of garden-based learning from science education to STEM education
Authors: Gulhan Filiz
Published: March 2023

In this review study, the inclusive potential that emerges when garden-based learning, which has long been considered within the framework of science education in the literature, is handled within the framework of STEM has been examined. The research calls for addressing garden-based learning in relation to STEM education. In particular, he suggests that digital tools and landscape architecture elements related to the integration of the engineering discipline into the garden can be mentioned, permaculture design can be applied, and wall gardens can be made in narrow spaces. STEM suggests that there is a need for teacher training for garden-based learning and that this can be achieved especially through collaborative work. In addition, it argues that STEM garden-based learning practices can turn into a nature mobilization beyond a teaching practice, by associating gardening studies with other school stakeholders, as well as integrating the disciplines in STEM with a purpose.

Differential expression of ARNTL2 in colorectal cancer.
Authors: Mamoor Shahan
Published: March 2023

Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential expression of the gene encoding aryl hydrocarbon receptor nuclear translocator-like 2, ARNTL2, when comparing colorectal tumors to the tissue of origin, the colon. ARNTL2 mRNA was present at significantly higher quantities in tumors of the colon as compared to normal colorectal tissue. Analysis of human survival data revealed that expression of ARNTL2 in rectal tumors was correlated with overall survival in patients with rectal cancer. ARNTL2 expression changes may be important for the initiation or progression of human CRC.

Importance: Forgiveness interventions have been shown in prior randomized trials to reduce depression and anxiety symptoms. Most such interventions require trained therapists, limiting scalability. Objective: To determine whether a brief self-directed forgiveness workbook intervention could alter forgiveness, depression symptoms, and anxiety symptoms. Design: A multi-site randomized waitlist-controlled trial was conducted among 4,598 participants. Recruitment occurred from February 11, 2020 to September 30, 2021. Final follow-up occured October 25, 2021. Setting: Participants were recruited from community-based samples in sites in Colombia, Hong Kong, Indonesia, South Africa, and Ukraine. Participants: Individuals (N = 7,837) were screened for eligibility. For inclusion, participants needed to be ≥18 years and have experienced an interpersonal transgression. Based on these criteria, 4,786 individuals were randomized, but 55 individuals were excluded for suspicious/fraudulent online participation, and 133 were excluded for not providing age or indicating age below 18. The analytic sample consisted of N = 4,598. Interventions: At each site, participants were randomly assigned to either immediate receipt of a self-directed forgiveness workbook intervention, or to receipt after a two-week delay. Main Outcomes and Measures: The primary outcomes were unforgiveness (Transgression-Related Interpersonal Motivations Inventory-18), depression symptoms, and anxiety symptoms (Brief Symptom Inventory-18) measured at two weeks following intervention assignment. Results: The study sample was median age 26 and 73% female. At two weeks follow-up, unforgiveness was lower among the immediate-treatment group compared to the delayed-treatment group (standardized mean difference=-0.52 [95% CI=-0.58, -0.46]); similar patterns were found for depression (standardized mean difference=-0.22 [95% CI=-0.28, -0.16]) and anxiety symptoms (standardized mean difference=-0.21 [95% CI=-0.27, -0.15]). Conclusions and Relevance: A brief workbook intervention promoted forgiveness and reduced depression and anxiety symptoms. The promotion of forgiveness with such workbooks has the potential for widespread dissemination to improve global mental health. Trial Registration: ClinicalTrials.gov Identifier: NCT04257773.
