Published: September 2021

Sutami Reservoir is one of the multipurpose reservoirs used in the supply of water. The main problem that occurs is a decrease in water quality caused by sources of pollution from agricultural waste, domestic waste, and industrial waste from the upstream part of the reservoir. This study aims to determine water quality during dry season using DOE-WQI, Pollution Index, Oregon-WQI, and Prati Index with parameters based on BOD, COD, DO, NH3-N, TSS, pH, NO3, and PO4, as well as to calculate the load capacity of reservoir pollution. The results obtained of water quality status using the DOE-WQI, Pollution Index, and Prati Index method is lightly polluted. Using the Oregon-WQI method, showed different results, that is heavily polluted, it was caused by differences in the use of parameters. The trophic status in the dry season of 2016 is 60%-80% Eutrophic. Total-P levels in upstream, middle, and downstream sections were 89,20 mg/m3, 86,733 mg/m3, and 76,667 mg/m3. The pollution load capacity of Sutami Reservoir in the upstream, middle, and downstream sections, are 12,448 mg/m3, 15,291 mg/m3, and 26,894 mg/m3. By comparing the value of Total-P and the pollution load capacity, it shows that Total-P exceed the limit of reservoir's pollution load capacity.Â Waduk Sutami menjadi salah satu waduk serbaguna yang digunakan dalam penyediaan air baku. Permasalahan utama yang terjadiialah adanya penurunan kualitas air yang disebabkan oleh sumber pencemaran limbah pertanian, limbah domestik, dan limbah industri di bagian hulu waduk. Penelitian ini bertujuan untuk menentukan kualitas air pada musim kemarau dengan menggunakan metode DOE-WQI, Indeks Pencemaran,Oregon-WQI, dan Prati Index berdasarkan parameter BOD, COD, DO, NH3-N, TSS, pH, NO3, dan PO4, serta untuk menghitung daya tampung beban pencemaranwaduk. Hasil yang didapatkan dari analisis kualitas air dengan menggunakanmetode DOE-WQI,Indeks Pencemaran, danPrati Indexadalah tercemar ringan. Pada metode Oregon-WQI menampilkan hasil yang berbeda yaitu tercemar berat, hal itu disebabkan oleh adanya perbedaan penggunaan parameter. Status trofik di musim kering tahun 2016 mengalami eutrofikasi sebesar 60% - 80% Eutrof. Diketahui kadar Total-P untuk bagian hulu, tengah, dan hilir antara lain 89,20 mg/m3, 86,733 mg/m3, dan 76,667 mg/m3. Besarnya daya tampung beban pencemaran Waduk Sutami pada bagian hulu, tengah, dan hilir yaitu 12,448 mg/m3, 15,291 mg/m3, dan 26,894 mg/m3. Dengan perbandingan kadar Total-P dan nilai daya tampungnya, maka memperlihatkan bahwa kadar Total-P melampaui batas kapasitas tampungan beban pencemaran waduk
Interpretation of a 12-Lead Electrocardiogram by Medical Students: Quantitative Eye-Tracking Approach
Authors: Tahri Sqalli Mohammed , Al-Thani Dena , Elshazly Mohamed B , Al-Hijji ‪Mohammed 
Published: September 2021

Background
Accurate interpretation of a 12-lead electrocardiogram (ECG) demands high levels of skill and expertise. Early training in medical school plays an important role in building the ECG interpretation skill. Thus, understanding how medical students perform the task of interpretation is important for improving this skill.

Objective
We aimed to use eye tracking as a tool to research how eye fixation can be used to gain a deeper understanding of how medical students interpret ECGs.

Methods
In total, 16 medical students were recruited to interpret 10 different ECGs each. Their eye movements were recorded using an eye tracker. Fixation heatmaps of where the students looked were generated from the collected data set. Statistical analysis was conducted on the fixation count and duration using the Mann-Whitney U test and the Kruskal-Wallis test.

Results
The average percentage of correct interpretations was 55.63%, with an SD of 4.63%. After analyzing the average fixation duration, we found that medical students study the three lower leads (rhythm strips) the most using a top-down approach: lead II (mean=2727 ms, SD=456), followed by leads V1 (mean=1476 ms, SD=320) and V5 (mean=1301 ms, SD=236). We also found that medical students develop a personal system of interpretation that adapts to the nature and complexity of the diagnosis. In addition, we found that medical students consider some leads as their guiding point toward finding a hint leading to the correct interpretation.

Conclusions
The use of eye tracking successfully provides a quantitative explanation of how medical students learn to interpret a 12-lead ECG.
Accessing Patient Electronic Health Record Portals Safely Using Social Credentials: Demonstration Pilot Study
Authors: SooHoo Spencer , Keller Michelle S , Moyse Harold , Robbins Benjamin , McLaughlin Matthew , Arora Ajay , Burger Abigail , Huang Lilith , Huang Shao-Chi , Goud Anil , Truong Lyna , Rodriguez Donaldo , Roberts Pamela 
Published: September 2021

Background
Patient portals allow communication with clinicians, access to test results, appointments, etc, and generally requires another set of log-ins and passwords, which can become cumbersome, as patients often have records at multiple institutions. Social credentials (eg, Google and Facebook) are increasingly used as a federated identity to allow access and reduce the password burden. Single Federated Identity Log-in for Electronic health records (Single-FILE) is a real-world test of the feasibility and acceptability of federated social credentials for patients to access their electronic health records (EHRs) at multiple organizations with a single sign-on (SSO).

Objective
This study aims to deploy a federated identity system for health care in a real-world environment so patients can safely use a social identity to access their EHR data at multiple organizations. This will help identify barriers and inform guidance for the deployment of such systems.

Methods
Single-FILE allowed patients to pick a social identity (such as Google or Facebook) as a federated identity for multisite EHR patient portal access with an SSO. Binding the identity to the patient’s EHR records was performed by confirming that the patient had a valid portal log-in and sending a one-time passcode to a telephone (SMS text message or voice) number retrieved from the EHR. This reduced the risk of stolen EHR portal credentials. For a real-world test, we recruited 8 patients and (or) their caregivers who had EHR data at 2 independent health care facilities, enrolled them into Single-FILE, and allowed them to use their social identity credentials to access their patient records. We used a short qualitative interview to assess their interest and use of a federated identity for SSO. Single-FILE was implemented as a web-based patient portal, although the concept can be readily implemented on a variety of mobile platforms.

Results
We interviewed the patients and their caregivers to assess their comfort levels with using a social identity for access. Patients noted that they appreciated only having to remember 1 log-in as part of Single-FILE and being able to sign up through Facebook.

Conclusions
Our results indicate that from a technical perspective, a social identity can be used as a federated identity that is bound to a patient’s EHR data. The one-time passcode sent to the patient’s EHR phone number provided assurance that the binding is valid. The patients indicated that they were comfortable with using their social credentials instead of having to remember the log-in credentials for their EHR portal. Our experience will help inform the implementation of federated identity systems in health care in the United States.
Smartband-Based Automatic Smoking Detection and Real-time Mindfulness Intervention: Protocol for a Feasibility Trial
Authors: Horvath Mark , Grutman Aurora , O'Malley Stephanie S , Gueorguieva Ralitza , Khan Nashmia , Brewer Judson A , Garrison Kathleen A 
Published: September 2021

Background
Smoking is the leading cause of preventable death in the United States. Smoking cessation interventions delivered by smartphone apps are a promising tool for helping smokers quit. However, currently available smartphone apps for smoking cessation have not exploited their unique potential advantages to aid quitting. Notably, few to no available apps use wearable technologies, most apps require users to self-report their smoking, and few to no apps deliver treatment automatically contingent upon smoking.

Objective
This pilot trial tests the feasibility of using a smartband and smartphone to monitor and detect smoking and deliver brief mindfulness interventions in real time to reduce smoking.

Methods
Daily smokers (N=100, ≥5 cigarettes per day) wear a smartband for 60 days to monitor and detect smoking, notify them about their smoking events in real time, and deliver real-time brief mindfulness exercises triggered by detected smoking events or targeted at predicted smoking events. Smokers set a quit date at 30 days. A three-step intervention to reduce smoking is tested. First, participants wear a smartband to monitor and detect smoking, and notify them of smoking events in real time to bring awareness to smoking and triggers for 21 days. Next, a “mindful smoking” exercise is triggered by detected smoking events to bring a clear recognition of the actual effects of smoking for 7 days. Finally, after their quit date, a “RAIN” (recognize, allow, investigate, nonidentification) exercise is delivered to predicted smoking events (based on the initial 3 weeks of tracking smoking data) to help smokers learn to work mindfully with cravings rather than smoke for 30 days. The primary outcomes are feasibility measures of treatment fidelity, adherence, and acceptability. The secondary outcomes are smoking rates at end of treatment.

Results
Recruitment for this trial started in May 2021 and will continue until November 2021 or until enrollment is completed. Data monitoring and management are ongoing for enrolled participants. The final 60-day end of treatment data is anticipated in January 2022. We expect that all trial results will be available in April 2022.

Conclusions
Findings will provide data and information on the feasibility of using a smartband and smartphone to monitor and detect smoking and deliver real-time brief mindfulness interventions, and whether the intervention warrants additional testing for smoking cessation.

Detecting Subclinical Social Anxiety Using Physiological Data From a Wrist-Worn Wearable: Small-Scale Feasibility Study
Authors: Shaukat-Jali Ruksana , van Zalk Nejra , Boyle David Edward 
Published: September 2021

Background
Subclinical (ie, threshold) social anxiety can greatly affect young people’s lives, but existing solutions appear inadequate considering its rising prevalence. Wearable sensors may provide a novel way to detect social anxiety and result in new opportunities for monitoring and treatment, which would be greatly beneficial for persons with social anxiety, society, and health care services. Nevertheless, indicators such as skin temperature measured by wrist-worn sensors have not been used in prior work on physiological social anxiety detection.

Objective
This study aimed to investigate whether subclinical social anxiety in young adults can be detected using physiological data obtained from wearable sensors, including heart rate, skin temperature, and electrodermal activity (EDA).

Methods
Young adults (N=12) with self-reported subclinical social anxiety (measured using the widely used self-reported version of the Liebowitz Social Anxiety Scale) participated in an impromptu speech task. Physiological data were collected using an E4 Empatica wearable device. Using the preprocessed data and following a supervised machine learning approach, various classification algorithms such as Support Vector Machine, Decision Tree, Random Forest, and K-Nearest Neighbours (KNN) were used to develop models for 3 different contexts. Models were trained to differentiate (1) between baseline and socially anxious states, (2) among baseline, anticipation anxiety, and reactive anxiety states, and (3) social anxiety among individuals with social anxiety of differing severity. The predictive capability of the singular modalities was also explored in each of the 3 supervised learning experiments. The generalizability of the developed models was evaluated using 10-fold cross-validation as a performance index.

Results
With modalities combined, the developed models yielded accuracies between 97.54% and 99.48% when differentiating between baseline and socially anxious states. Models trained to differentiate among baseline, anticipation anxiety, and reactive anxiety states yielded accuracies between 95.18% and 98.10%. Furthermore, the models developed to differentiate between social anxiety experienced by individuals with anxiety of differing severity scores successfully classified with accuracies between 98.86% and 99.52%. Surprisingly, EDA was identified as the most effective singular modality when differentiating between baseline and social anxiety states, whereas ST was the most effective modality when differentiating anxiety among individuals with social anxiety of differing severity.

Conclusions
The results indicate that it is possible to accurately detect social anxiety as well as distinguish between levels of severity in young adults by leveraging physiological data collected from wearable sensors.

Introducción: El automanejo en personas con alguna condición crónica no es una opción, realizarlo adecuadamente marca la diferencia en la calidad de vida de las personas con una enfermedad crónica, como son cáncer, diabetes e hipertensión arterial. Existe aún muy poco conocimiento sobre similitudes o diferencias del automanejo entre estos tres grupos de individuos.
Objetivo: Describir el automanejo a través del análisis de las diferentes dimensiones en tres grupos de personas con diabetes, hipertensión y cáncer.
Método: Estudio transversal-comparativo con n= 562 personas: 160 con cáncer, 187 con diabetes y 215 con hipertensión. Muestreo no probabilístico intencional. Se aplicó el instrumento Partners in Health (PIH). Se utilizó la estadística descriptiva y no paramétrica a través de la prueba de Kruskall Wallis para comparar tres muestras independientes, se calculó el efecto de la diferencia y la potencia estadística.
Resultados: El índice general de automanejo y sus dimensiones en los tres grupos están por debajo de la media general respectivamente. No se encontraron diferencias entre los grupos según su diagnóstico médico (diabetes, hipertensión y cáncer). ρ<0.001; (1-β>.80 y d> .20).
Discusión y Conclusiones: Las personas con alguna condición crónica presentan un automanejo inadecuado, no se identifican diferencias en el automanejo global y sus dimensiones según diagnóstico médico. En consecuencia, se hace relevante la implementación de programas genéricos que promueven el automanejo, sobre todo en el primer nivel de atención, además se debe incrementar las investigaciones en Latinoamérica, con mayor atención en personas con cáncer.

The Potential of Jenderal Soedirman's Short Film as Learning Media in National Events of the Colonial Period’s Material for Fifth Graders: A Semiotics Analysis
Authors: Supriatna Encep , Savira Ratu Tiara 
Published: September 2021

The stories of Jenderal Soedirman, one of the national instrumental figures in seizing Indonesia's independence from the invaders, have been visualized in many films. Films containing events about the struggle for independence need to be studied, understood and remembered so that the values of nationalism are embedded. This film has the potential to be used as a learning media in packaging stories into interesting and meaningful learning for elementary school students. This leads researchers to analyze Jenderal Soedirman’s short film as learning media on the IPS national events of the time colonization of 5th graders of elementary school. This study used a qualitative approach in observing an individual behavior and to describe the data of research’s findings in detail and moderation. The research method used was Roland Barthes’s semiotic analysis that focused on signs and symbols as markers interpreted by denotation, connotation and myth on the film. The data collecting techniques used were observation, student's journal, questionnaires and documentation. Based on research and discussion of semiotic analysis of Jenderal Soedirman’s short film as learning media on three meanings, it is evident that researchers can better understand the hidden meaning contained in the film. The researchers deeply identify the figure of Jenderal Soedirman, the myth believed by the Indonesian freedom people during his struggle and this film potential to be used as a learning media because it increases students’ learning motivation by a score of 3,00 earned in a reasonably good category.
