Improving Well-being With a Mobile Artificial Intelligence–Powered Acceptance Commitment Therapy Tool: Pragmatic Retrospective Study
Authors: Naor Navot , Frenkel Alex , Winsberg Mirène
Published: May 2022

Background

Research and dissemination of smartphone apps to deliver coaching and psychological driven intervention had seen a great surge in recent years. Notably, Acceptance Commitment Therapy (ACT) protocols were shown to be uniquely effective in treating symptoms for both depression and anxiety when delivered through smartphone apps. The aim of this study is to expand on that work and test the suitability of artificial intelligence–driven interventions delivered directly through popular texting apps.

Objective

This study evaluated our hypothesis that using Kai.ai will result in improved well-being.

Methods

We performed a pragmatic retrospective analysis of 2909 users who used Kai.ai on one of the top messaging apps (iMessage, WhatsApp, Discord, Telegram, etc). Users’ well-being levels were tracked using the World Health Organization-Five Well-Being Index throughout the engagement with service. A 1-tailed paired samples t test was used to assess well-being levels before and after usage, and hierarchical linear modeling was used to examine the change in symptoms over time.

Results

The median well-being score at the last measurement was higher (median 52) than that at the start of the intervention (median 40), indicating a significant improvement (W=2682927; P<.001). Furthermore, HLM results showed that the improvement in well-being was linearly related to the number of daily messages a user sent (β=.029; t81.36=4; P<.001), as well as the interaction between the number of messages and unique number of days (β=–.0003; t81.36=–2.2; P=.03).

Conclusions

Mobile-based ACT interventions are effective means to improve individuals’ well-being. Our findings further demonstrate Kai.ai’s great promise in helping individuals improve and maintain high levels of well-being and thus improve their daily lives.

Authors: Liu Sam , Smith Nicholas , Nuss Kayla , Perdew Megan , Adiputranto Dimas , Naylor Patti-Jean
Published: May 2022

Background

The Early Intervention Program (EIP) was a 10-week, blended, in-person and online lifestyle intervention for families with children who were off the healthy weight trajectory. The engagement pattern and the dose response of EIP have not been examined.

Objective

The aims of this paper are to examine families’ engagement patterns with the EIP and to evaluate the dose-response relationship between EIP engagement patterns and physical activity and healthy eating–related outcomes at 10 weeks.

Methods

Families with children (8-12 years old) who are off the healthy weight trajectory (child BMI ≥85th percentile for age and sex) were recruited. Pre- and postintervention questionnaires assessed child lifestyle behaviors, parental support behaviors, family lifestyle habits, as well as parental physical activity and healthy-eating identity. Hierarchical cluster analysis of both in-person and online components was used to classify engagement patterns. Regression analysis assessed differences in outcomes by engagement groups.

Results

Two distinct clusters of engagement groups were identified (N=66), which were in-person (IP; n=40, 61%) and in-person + online (IP+; n=26, 39%) engagement. Relative to the IP group at week 10, IP+ showed a greater child moderate-to-vigorous physical activity level (1.53, SD 0.56; P=.008), child physical activity confidence (1.04, SD 0.37; P=.007), parental support for child physical activity (5.54, SD 2.57; P=.04) and healthy eating (2.43, SD 1.16; P=.04), family habits for physical activity (3.02, SD 1.50; P=.049) and healthy eating (3.95, SD 1.84; P=.04), and parental identity for physical activity (2.82, SD 1.19; P=.02).

Conclusions

The online EIP portal complemented the in-person sessions. Additional engagement with the portal was associated with greater improvements in child physical activity and parental support behaviors, habits, and identity for physical activity.
The Logistics of Medication and Patient Flow in Video-Based Virtual Clinics During a Sudden COVID-19 Outbreak in Taiwan: Observational Study
Authors: Chen Ying-Hsien , Wu Hui-Wen , Huang Ching-Chang , Lee Jen-Kuang , Yang Li-Tan , Hsu Tse-Pin , Hung Chi-Sheng , Ho Yi-Lwun
Published: May 2022

Background

The COVID-19 pandemic was well controlled in Taiwan until an outbreak in May 2021. Telemedicine was rapidly implemented to avoid further patient exposure and to unload the already burdened medical system.

Objective

To understand the effect of COVID-19 on the implementation of video-based virtual clinic visits during this outbreak, we analyzed the logistics of prescribing medications and patient flow for such virtual visits at a tertiary medical center.

Methods

We retrospectively collected information on video-based virtual clinic visits and face-to-face outpatient visits from May 1 to August 31, 2021, from the administrative database at National Taiwan University Hospital. The number of daily new confirmed COVID-19 cases in Taiwan was obtained from an open resource.

Results

There were 782 virtual clinic visits during these 3 months, mostly for the departments of internal medicine, neurology, and surgery. The 3 most common categories of medications prescribed were cardiovascular, diabetic, and gastrointestinal, of which cardiovascular medications comprised around one-third of all medications prescribed during virtual clinic visits. The number of virtual clinic visits was significantly correlated with the number of daily new confirmed COVID-19 cases, with approximately a 20-day delay (correlation coefficient 0.735; P<.001). The patient waiting time for video-based virtual clinic visits was significantly shorter compared with face-to-face clinic visits during the same period (median 3, IQR 2-6 min vs median 20, IQR 9-42 min; rank sum P<.001). Although the time saved was appreciated by the patients, online payment with direct delivery of medications without the need to visit a hospital was still their major concern.

Conclusions

Our data showed that video-based virtual clinics can be implemented rapidly after a COVID-19 outbreak. The virtual clinics were efficient, as demonstrated by the significantly reduced waiting time. However, there are still some barriers to the large-scale implementation of video-based virtual clinics. Better preparation is required to improve performance in possible future large outbreaks.
Integrated Health Record Viewers and Reduction in Duplicate Medical Imaging: Retrospective Observational Analysis (Preprint)
Authors: Yuan Yingzhe , Price Megan , Schmidt David F , Ward Merry , Nebeker Jonathan , Pizer Steven
Published: May 2022

BACKGROUND

Health information exchange and multiplatform health record viewers support more informed medical decisions, improve quality of care, and reduce the risk of adverse outcomes due to fragmentation and discontinuity in care during transition of care. An example of a multiplatform health record viewer is the VA/DoD Joint Longitudinal Viewer (JLV), which supports the Department of Veterans Affairs (VA) and Department of Defense (DoD) health care providers with read-only access to patient medical records integrated from multiple sources. JLV is intended to support more informed medical decisions such as reducing duplicate medical imaging when previous image study results may meet current clinical needs.

OBJECTIVE

We estimated the impact of provider usage of JLV on duplicate imaging for service members transitioning from the DoD to the VA health care system.

METHODS

We conducted a retrospective cross-sectional study in fiscal year 2018 to examine the relationship between providers’ use of JLV and the likelihood of ordering duplicate images. Our sample included recently separated service members who had a VA primary care visit in fiscal year 2018 within 90 days of a DoD imaging study. Patients who received at least one imaging study at VA within 90 days of a DoD imaging study of the same imaging mode and on the same body part are considered to have received potentially duplicate imaging studies. We use a logistic regression model with “JLV provider” (providers with 1 or more JLV audits in the prior 6 months) as the independent variable to estimate the relationship between JLV use and ordering of duplicate images. Control variables included provider image ordering rates in the prior 6 months, provider type, patient demographics (age, race, gender), and clinical characteristics (Elixhauser comorbidity score).

RESULTS

Providers known to utilize JLV in the prior 6 months order fewer duplicate images relative to providers not utilizing JLV for similar visits over time (odds ratio 0.44, 95% CI 0.24-0.78; P=.005). This effect is robust across multiple specifications of linear and logistic regression models. The provider’s practice pattern of ordering image studies and the patient’s health status are powerful confounders.

CONCLUSIONS

This study provides evidence that adoption of a longitudinal viewer of health records from multiple electronic health record systems is associated with a reduced likelihood of ordering duplicate images. Investments in health information exchange systems may be effective ways to improve the quality of care and reduce adverse outcomes for patients experiencing fragmentation and discontinuity of care.
Exploring Online Peer Support Groups for Adults Experiencing Long COVID in the United Kingdom: Qualitative Interview Study (Preprint)
Authors: Day Hannah L S
Published: May 2022

BACKGROUND

Long COVID is an emerging public health concern. A growing number of individuals are experiencing prolonged, multifaceted health challenges and accompanying social impacts after COVID-19 infections. Support services in the United Kingdom remain insufficient and fraught with complexity. Responding to persistent gaps in care, patients joined forces in online peer support groups. However, little is known about how these groups impact patients with long COVID and their lived experiences of the condition.

OBJECTIVE

The aim of this study is to explore the roles that online peer support groups take on and the impact they have on patients experiencing and recovering from long COVID in the United Kingdom. In doing so, this study aims to identify ways to inform future long COVID care, including online peer support and broader long COVID care structures.

METHODS

I conducted 11 semistructured interviews virtually on Zoom in July 2021. Participants had long COVID, were UK-based, and used long COVID online peer support groups. Topics discussed in interviews included what led participants to these groups, experiences within them, and feelings about the roles that the groups took on. I analyzed the results by manually conducting thematic analysis.

RESULTS

Long COVID online peer support groups had numerous roles, significantly impacting users. I identified 5 themes and 13 subthemes through thematic analysis. The identified themes were as follows: (1) filling professional care gaps, (2) societal awareness, (3) engagement behavior, (4) diversity, and (5) social connections. Given the void of professional support, those experiencing long COVID gained some benefit from these groups. However, participants emphasized notable concerns about the all-encompassing roles these groups embody and speculated over potential improvements.

CONCLUSIONS

If used appropriately, online peer support groups could be immensely beneficial for patient well-being, beyond simply filling gaps in long COVID care. However, it appears many groups take on more than they can manage and become potentially harmful. Through prioritizing patient voices, long COVID care could be restructured to maximize peer support’s benefits within broader care structures.

Published: May 2022

BACKGROUND

Mobile applications play an important role in the management, care, and prevention of infectious diseases, thereby playing a significant role in self-care.

OBJECTIVE

This study aimed to design, develop, and evaluate an educational mobile-based self-care application in order to help the self-prevention of the COVID-19 disease in undeveloped countries.

METHODS

The self-care management application was designed using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) educational model. The application’s usability and its impact were tested by 27 participants using two questionnaires: Mobile Health App Usability (MAUQ) and Self-Care Inventory (SCI). The study design implied pre- and post-testing. The self-care management application was designed using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) educational model. The application’s impact was tested by 27 participants using the questionnaire Self-Care Inventory (SCI). The study design implied pre-and post-testing.

RESULTS

An Android application called MyShield was developed. The results of pre- and post-tests show that MyShield has a performance average of 4.17 in the physical health dimension, and an average of 3.88 in mental wellbeing (on a scale range 0 to 5), and thus shows positive effects on self-care skills. In terms of usability and satisfaction, MyShield received the highest score on the "Interface and Satisfaction” component, followed by “Ease of use” and “Usefulness”.

CONCLUSIONS

MyShield facilitates learning self-care skills at home and during quarantine and increases information acquisition. Given its low development cost and ADDIE educational design on which it is based, the application has to be considered quite helpful in undeveloped countries.
Distribution features of the weather conditions in Nha Trang Bay (The South China Sea)
Authors: Le Mau Dinh , Vlasova Galina , Nguyen Dung Thi Thuy , Pham Hoan Sy , Nguyen Tuan Van
Published: May 2022

Nha Trang Bay is a semi-envelop coastal basin. It is located on the west coast of the South China Sea as well as in the south of the central part of the Vietnamese coast. The climate of the bay belongs to the sub-equatorial zone or to the zone of equatorial-tropical monsoons. Determination of the meteorological characteristics of an ocean region, especially for nearshore bay waters, plays a very important role in the sustainable development of the social-economical system of Vietnam. This paper presents a spatial and temporal long-term analysis of several meteorological characteristics in Nha Trang Bay, such as wind, tropical cyclones, air temperature, air humidity, and rainfall. The meteorological data were collected from the Nha Trang meteorological station during 1977–2015 (wind data until 2020).

The data for typhoons were extracted from the National Weather Service (USA) and the Japan Meteorological Agency during 1945–2015. Statistical methods for collecting and analyzing data to estimate the statistical parameters of meteorological characteristics were used in the study.

A study of results shows that the meteorological characteristics in the Nha Trang Bay are a seasonal variation of the East Asian monsoon (northeastern-NE and southwestern-SW monsoons).

The winds in Nha Trang Bay are the seasonal change, influenced by the NE monsoon from October to April and the SW monsoon from June to August. May and September are the transition periods.

Nha Trang Bay has a temperate tropical climate because the temperature regime of the bay ranges from less than 25°C in the winter and more than 28°C in the summer.

Extreme conditions, including typhoon activity and heavy rainfall (coinciding with high humidity), occurred in October, November, and December.

Published: May 2022

Harmsiopanax aculeatus leaf, locally name kapur, has been use traditionally to treat malaria in Maluku, Indonesia. However, the scientific evidences that support its use are still limited. This study aimed to investigate antiplasmodial activity of H. aculeatus leaf extract and its cytotoxicity on cancer cells line. Three extracts i.e. methanolic, n-hexanic and ethyl acetate extracts were evaluated for their in vitro activity against Plasmodium falciparum FCR3 strain using microscopic method. Cytotoxicity of the extracts on T47D, HeLa and Vero cells lines were determined using MTT assay method. The inhibitory concentration 50% (IC50) against P. falciparum or the cells lines growth was determined using probit analysis. Furthermore, their selectivity index (SI) were determined. The results showed that the methanolic extract was the most active extract with an IC50value of 13.82 μg/mL and the most selective with a SI value of 172.84. The three extracts tested exhibited weak or no cytotoxicity against the cells lines used with IC50 values ranged 101-2388.69 μg/mL. Further study will be conducted to isolate active antiplasmodial compounds from the methanol extract.

Foreign direct investment, economic growth, and unemployment: Evidence from developing countries
Authors: Kukaj Halil , Nimani Artan , Usaj Vesel
Published: May 2022

High unemployment is one of the major difficulties confronting most modern countries, putting social, economic, and political strain on policymakers. Foreign direct investment (FDI) is critical to a country’s economic development, particularly in transitional economies. FDI is a major source of capital inflows to developing countries. FDI affects the level of employment in the host country, in addition to its many other effects. The research is based on the studies of Johnny, Timipere, and Krokeme (2018) and Zeb, Qiang, and Sharif (2014) that have examined these variables in this paper. This study investigates the relationship between FDI, economic growth, and unemployment to quantify and assess the relationship in selected developing countries or Western Balkans countries according to these variables. Data for the developing countries of Western Balkan were collected in the observed period 2015–2019. Differences between countries were explored in terms of FDI, gross domestic product (GDP), and unemployment using the data produced from the one-way analysis of variance (ANOVA) test. According to regression analysis, FDI and GDP have a considerable impact on country unemployment. The results showed that FDI and GDP have an effect in decrease unemployment in the developing countries examined.
Clinical relevance of major allergens compared to extract-based IgE diagnosis in pollen-allergic patients in Austria
Authors: Horak Fritz , Bohle Barbara , Hartl C. , Horvathova E. , Sotoudeh M. , Szepfalusi Zsolt
Published: May 2022

Background: Pollen-allergy is common in Austria. The present
study investigated if the use of major pollen-allergens on top of
extract-based diagnosis may improve the diagnostic accuracy and if this
additional knowledge helps to identify patients eligible for
allergen-specific immunotherapy (AIT). Methods: In this
retrospective database analysis patients sensitized to a grass, birch,
ash-tree, mugwort or ragweed were investigated and results of pollen
extracts compared to the respective major allergens (Phl p 1, Bet v 1,
Ole e 1, Art v 1, Amb a 1) were assessed. Furthermore, extract- and MD-
results of patients double-sensitized to both tree-extracts or both
weed-extracts were compared. In patients with discrepant results, their
charts were reviewed to define if this difference was clinically
relevant in regard to their doctors´ AIT-decision. Results:
4234 patients (age 1.2-89.7yrs) could be included in the analyses. There
was high agreement between extract-based IgE results and major allergens
concerning single-sensitization to grass/Phl p 1+5 (94.4%), birch/Bet v
1 (94.4%), and ash-tree/Ole e 1 (82.9%), with lower agreement between
mugwort/Art v 1 (64.1%) and ragweed/Amb a 1 (73.8%). Among patients
double-sensitized to both tree pollen extracts only 76% were also
sensitized to both major allergens (Bet v 1 and Ole e 1) and therefore
suitable for AIT. In patients double-sensitized to both weeds, only 25%
were also sensitized to both major allergens (Art v 1 and Amb a 1),
46.2% of mugwort extract positive patients tested negative for Art v 1.
Of these patients, 41.3% were recommended a ragweed AIT as their Amb a
1 results were positive. Conclusion: MD can improve diagnostic
accuracy in patients with pollen-allergy and should be implemented in
standard clinical care, especially when double-sensitization to
allergens of plants with overlapping pollen seasons cannot be clearly
discerned by patients´ symptoms alone.
British Illustrated Editions of “Uncle Tom's Cabin”: Race, Working-Class Literacy, and Transatlantic Reprinting in the 1850s
Authors: HOLOHAN MARIANNE
Published: May 2022

Many cheap illustrated editions of Harriet Beecher Stowe's Uncle Tom's Cabin were brought out by reprint publishers in Britain in 1852 and 1853. While much scholarship about the novel's publication focuses on America, more copies of Uncle Tom's Cabin were sold in Britain, thanks to a laissez-faire publishing atmosphere that allowed reprinting to flourish and an expanded reading public that included the working classes. Most British editions of the novel were cheap editions intended for a mass readership, and many of these contained illustrations that conveyed varying ideas about race. This article investigates the publishing milieu that made cheap illustrated editions of Uncle Tom's Cabin bestsellers, interrogates the implications of race being illustrated for a white working-class readership, and uses one reprint publisher's illustrated edition as a case study to show why British illustrated editions of the novel deserve more scholarly attention.
Owen Wister: A Primary Bibliography
Authors: SCHARNHORST GARY
Published: May 2022

Best known today for his writings about the American West, which he visited over twenty-five times between 1885 and 1920, Owen Wister was remarkably versatile, a poet, dramatist, essayist, novelist of manners, journalist, book critic, biographer and historian, satirist, and author of children's books. This bibliography of his writings increases by over half, to over 250, the number of items Wister is known to have published, including several schoolboy exercises contributed to his prep school newspaper and the Harvard Crimson, many prefaces or introductions to books by his friends, and memoirs of his lifelong friend and Harvard classmate Theodore Roosevelt.
The Unknown Van Vechten and His Impact on His Times
Authors: SCRUGGS CHARLES
Published: May 2022

Edward White's study of Carl Van Vechten is both a biography and a critical study of his multifaceted career—as novelist, essayist, photographer, and patron of the Harlem Renaissance. White also argues that Van Vechten anticipates the present-day interest in gay studies, for he focuses on a little-known side of Van Vechten's life, his homosexuality and his collection of gay erotica. Although White talks intelligently about Van Vechten's essays on the blues and his friendship with and advocacy of Gertrude Stein, he merely skims the surface when discussing Van Vechten's fiction, especially his most important and controversial novel, Nigger Heaven (1926). Although White is right to call Van Vechten a modernist, he exaggerates when he calls him a “tastemaker.” H. L. Mencken had a far greater influence on his generation, as Walter Lippman noted in 1926.
The Letters of a Man of Letters
Authors: DONALDSON SCOTT
Published: May 2022

This review-essay presents an overview of Malcolm Cowley's life as a professional man of letters. A poet at the beginning, Cowley became best known for books about twentieth-century literary history, enlivened by incisive personal portraits of its practitioners. As a writer and editor, he played a crucial role in establishing and advancing the careers of contemporaries Hemingway, Faulkner, and Fitzgerald, and of younger writers Cheever and Kerouac. During the 1930s and stretching into the next decade, Cowley was involved in the political wars as a fervent left-winger supporting communist causes, a passion he came to regret. These subjects emerge vividly in Hans Bak's edition of Cowley's letters, sent to a wide array of well-known poets and prose writers. The book, with a first-rate introduction by son Robert Cowley and periodic commentaries by Bak, reads like a biography in the making of this important and undervalued figure in American literary history.

Published: May 2022

Identifying the mechanisms behind the β-cell adaptation to failure is important to develop strategies to manage type 2 diabetes (T2D). Using db/db mice at early stages of the disease process, we took advantage of unbiased RNA sequencing to identify genes/pathways regulated by insulin resistance in β-cells. We demonstrate herein that islets from 4-week-old nonobese and nondiabetic leptin receptor–deficient db/db mice exhibited downregulation of several genes involved in cell cycle regulation and DNA repair. We identified the transcription factor Yin Yang 1 (YY1) as a common gene between both pathways. The expression of YY1 and its targeted genes was decreased in the db/db islets. We confirmed the reduction in YY1 expression in β-cells from diabetic db/db mice, mice fed a high-fat diet (HFD), and individuals with T2D. Chromatin immunoprecipitation sequencing profiling in EndoC-βH1 cells, a human pancreatic β-cell line, indicated that YY1 binding regions regulate cell cycle control and DNA damage recognition and repair. We then generated mouse models with constitutive and inducible YY1 deficiency in β-cells. YY1-deficient mice developed diabetes early in life due to β-cell loss. β-Cells from these mice exhibited higher DNA damage, cell cycle arrest, and cell death as well as decreased maturation markers. Tamoxifen-induced YY1 deficiency in mature β-cells impaired β-cell function and induced DNA damage. In summary, we identified YY1 as a critical factor for β-cell DNA repair and cell cycle progression.

Published: May 2022

Mistletoes are aerial hemiparasitic plant that infesting and parasitizing on wild and cultivated plants. They are can be categorized as generalist and specialist mistletoes according to their host plants diversity. Shannon index of the host plants diversity can be used to determine host specificity of mistletoes. Study aimed to know and determine host plants and host specificity of mistletoes in Purwodadi Botanic Garden was conducted in 2013, 2017 and 2021. Data of mistletoes and their hosts species was collected by explorative and descriptive methods in 2013, 2017, and 2021. Recorded data by observation in the fields were species and species number of mistletoes and their hosts. Observation of the misteltoes used binoculars to ditermine the species of the mistletoes. Identification of the mistletoes species and their hosts was conducted directly in the garden and undirectly by making herbarium specimens and taking photographs. The results showed that there were five species of mistletoes infested 142 species, 82 genera and 36 families of host plants namely Dendrophthoe pentandra, Macrosolen tetragonus, Scurrula atropurpurea, Viscum articulatum, and Viscum ovalifolium. There were significantly different between the mistletoe species and their Shannon index of host plants . D. pentandra was the most generalist or the least specialist to host plants with the highest Shannon index value of 2.20±0.10, whereas S. atropurpurea was the least generalist or the most specialist with Shannon index value of 0.16±0.09.

Kebutuhan informasi dan hiburan merupakan hal yang sangat diperlukan masyarakat di era globalisasi saat ini, termasuk kebutuhan tentang informasi geografis dan cuaca. Pada saat seperti ini mulai banyak yang mengembangkan antena tracker, yaitu antena pemancar yang dapat berubah-ubah posisi terhadap antena penerima, sehingga akan sangat berpengaruh terhadap proses transmisi data. Pada penelitian ini, objek yang diamati oleh antenna tracker berupa payload, yaitu untuk mengetahui kondisi geografis dan pantauan cuaca. Antena tracker bergerak pada sudut azimuth dan elevasi sehingga pemancar dan penerima dapat tersinkronisasi secara optimal. Antena tracker menggunakan GPS (Global Positioning System) yang berfungsi untuk menentukan posisi antena pemancar, motor DC Stepper, telemetri 433 Mhz, dan mikrokontroler Arduino Mega. Payload yang berisi sensor–sensor akan memberikan data menuju antena tracker, kemudian antena akan membaca data latitude dan longitude payload untuk menggerakkan antena agar mengikuti payload. Selanjutnya data-data yang diterima antena tracker akan dikirim menuju Ground Station (GS) dimana data yang menunjukkan pergerakan arah antena tracker juga akan ditampilkan pada GS dan data hasil pemantauan pada payload dapat dilihat melalui Arduino. Nilai distance (jarak horizontal payload dengan antena tracker) menunjukkan rata-rata nilai error 39.496 dengan 5 titik lokasi percobaan.

Pendidikan merupakan hal yang sangat penting bagi setiap orang tak terkecuali untuk anak berkebutuhan khusus. Sekolahan luar biasa yayasan pendidikan anak saestu putro (SLB-BC) YPASP merupakan salah satu sekolahan khusus untuk anak berkebutuhan khusus di Gondangrejo. Sekolahan ini memiliki beberapa anak berkebutuhan khusus salah satunya adalah tunagrahita. Anak tunagrahita memiliki keterbatasan dalam beberapa kemampuan sehingga membuat guru mengalami kendala dalam menyampaikan materi. Selain itu dengan hanya menggunakan media pembelajaran yang ada dalam proses belajar minat siswa menjadi kurang dan mudah bosan. Salah satunya dalam penyampaian materi matematika yaitu tentang pengenalan mata uang, guru masih menggunakan alat peraga berupa uang asli dan buku panduan. Sehingga hal ini menjadi kurang efektif karna guru harus menggunakan alat peraga yang tidak sedikit. Oleh sebab itu, penulis mengembangkan sebuah game edukasi berbasis android bernama Mari Mengenal Mata Uan sebagai metode pembelajaran yang baru. Dengan adanya game ini guru dapat lebih mudah menyampaikan materi dan manambah minat siswa. Penelitian dilakukan melalui 3 tahap. Tahap pertama yaitu melakukan observasi dan wawancara terhadap guru dan kepala sekolah di SLB-BC YPASP Gondangrejo. Tahap kedua penulis mengembangkan game menggunakan software Construct 2 sesuai kebutuhan. Tahap ketiga adalah implementasi dan pengujian. Pengujian aplikasi menggunakan metode blackbox menunjukan bahwa aplikasi dapat berjalan dengan baik dan sesuai harapan. Implementasi dilakukan dengan pengujian langsung terhadap responden dan memberikan kuisioner untuk mengukur kelayakan program. Hasil kuisioner menunjukan bahwa program layak dan bisa diterima oleh pengguna dengan presentase mencapai 88,5%.

Benostore shop is a shop that sells clothing equipment in Surakarta. Inventory management at Benostore stores is still conventional with the records in the ledger so that its performance is limited. Then an inventory information system was created to optimize inventory management at the Benostore store. The method used is the SDLC method with a waterfall approach using UML (integrated modeling language) which consists of use case diagrams and activity diagrams. This system is designed using the Hypertext Preprocessor (PHP) web programming language with the CodeIgniter version 3 framework and MySQL which is used for database design and data storage. This system will be tested using the BlackBox method and user acceptance test (UAT). UAT testing uses the interview method involving shop owners and employees. This research produces an inventory system that can be implemented in the Benostore shop.
