Developing an app for Android and iOS traditionally requires you to build two different versions. This is both costly and time consuming, which has led to the creation of many Cross-platform alternatives. One such alternative is to use a Progressive Web App (PWA). They are built like regular Web apps and include features previously unique to Native apps. Our focus is to compare PWAs to other Cross-platform solutions by measuring the performance of a PWA, Web app and Cordova app. Terms in the ecosystem are clarified due to inconsistencies, and the process of converting a Web app into a PWA is described. The measurements showed that the PWA and Cordova app had almost equal overall performance, and they were both faster than the Web app. This indicates that PWAs are a viable Cross-platform alternative, but more quantitative studies with performance in focus needs to be conducted due to the small scale of this work. Other aspects of PWAs also needs to be evaluated, such as app size and ease of development.

Throughout the development process within organizations, various complications can appear that can reduce the quality of a software or contribute to immense costs to organizations. This is especially true for organizations that operate in fields such as the health industry where stern rules and requirements are often a fact. This paper explores challenges that can arise during the development process of health applications as well as what effects these can have on the applications and organizations. The paper then examines how these difficulties can be prevented or mitigated. The intention is that this thesis should help organizations and developers to be able to go through a development process effectively without being overwhelmed by difficulties that can arise during the development process of health applications.

La presente investigación pretende abordar el diseño interactivo como medio de prevención a la sarcopenia, entendida como la pérdida de masa y potencia muscular en personas de la tercera edad. En la actualidad, se ha observado un bajo índice de actividad física en personas de 65 a 80 años. Según un artículo médico de la Universidad Peruana Cayetano Heredia, el porcentaje de adultos mayores con sobrepeso u obesidad en el Perú es de 21,4% y 11,9%, respectivamente (Penny, 2017). El desgaste en la capacidad de los órganos sensoriales son indicios considerables del avance en la adultez mayor. Una de las principales patologías que afecta al adulto mayor, es la disminución de músculo esquelético, el cual es causante de caídas, distensiones, distrofia muscular y enfermedades musculares. Estos factores generan la limitación funcional, pérdida de autonomía e incluso la muerte en el adulto mayor. Igualmente, la presente investigación busca brindar un aporte sólido al rol que desempeña el diseño interactivo en relación a la sarcopenia con el objetivo de prevenir o atenuar dicha patología. En paralelo a esta problemática, existen aplicaciones móviles interactivas enfocadas al diagnóstico de enfermedades primarias, mantener la mente activa y en general, preservar la salud del adulto mayor. Así pues, tras entender la relación de los factores claves en esta investigación, las conclusiones de este proyecto y la investigación del trabajo de campo que analizó a la población objeto de estudio, se propone desarrollar una aplicación móvil llamada Activos. Una solución planteada para promover la actividad física en el adulto mayor y atenuar la sarcopenia. En conclusión, las personas de la tercera edad que utilizaron el aplicativo móvil que se les presentó, argumentaron que es necesario ya que pueden realizar las rutinas de actividad física desde la comodidad de su hogar hasta en el parque. De este modo se beneficiarán, cuidarán su salud y además podrán acceder a posibles descuentos para sus consultas. / The present research aims to address interactive design as a means of prevention of sarcopenia, understood as the loss of muscle mass and power in the elderly. Currently, a low level of physical activity has been observed in people aged 65 to 80 years. According to a medical article from the Universidad Peruana Cayetano Heredia, the percentage of older adults who are overweight or obese in Peru is 21.4% and 11.9%, respectively (Penny, 2017). The wear on the capacity of the sensory organs are considerable indications of the advance in adulthood. One of the main pathologies that affects the elderly is the reduction of skeletal muscle, which is responsible for falls, strains, muscular dystrophy and muscle diseases. These factors generate functional limitation, loss of autonomy and even death in the elderly. Likewise, this research seeks to provide a solid contribution to the role played by interactive design in relation to sarcopenia with the aim of preventing or attenuating this pathology. In parallel to this problem, there are interactive mobile applications focused on the diagnosis of primary diseases, keeping the mind active and, in general, preserving the health of the elderly. Thus, after understanding the relationship of the key factors in this research, the conclusions of this project and the fieldwork research that analyzed the population under study, it is proposed to develop a mobile application called Assets. A solution proposed to promote physical activity in the elderly and attenuate sarcopenia. In conclusion, the elderly people who used the mobile application presented to them, argued that it is necessary since they can perform physical activity routines from the comfort of their home to the park. In this way they will benefit, take care of their health and also have access to possible discounts for their consultations. / Trabajo de investigación

College counseling centers (CCCs) have experienced funding and staffing setbacks in recent years, resulting in higher caseloads, counselor burnout, and bloated waitlists. Mobile Health (mHealth) interventions may offer a cost-effective and innovative solution. The authors developed ACT Daily, a prototype mHealth app based in Acceptance and Commitment Therapy (ACT). This study examined the feasibility and possible efficacy of ACT Daily as a brief intervention for individuals placed on CCC waitlists. A sample of 11 depressed/anxious clients waitlisted at a local CCC enrolled in the study, which followed a pre-post, open trial design. Participants received a brief online training that covered the basics of ACT and introduced the app’s functions and features. For the following 2 weeks, participants were asked to use ACT Daily every day. Results displayed high acceptability, usability, and satisfaction ratings across users. Significant improvements were observed on most ACT process measures, including overall psychological inflexibility. Findings from app usage and self-report measures supported ACT Daily’s ability to promote skill use in the moment. Analyses of in-app data indicated that ACT Daily’s skills were potentially effective in the moment and increased in strength over time. Furthermore, ACT Daily appeared to serve as a helpful pre-therapy tool due to significant reductions in depression and anxiety symptoms, as well as improvements in emotional self-awareness. Finally, the online training appeared to equip users with a sufficient comprehension of core ACT components and app training. While this pilot study suffered from a low sample size, this pattern of results encourages the application and dissemination of ACT mHealth apps as an added support for waitlisted CCC clients suffering from depression or anxiety. Moreover, it appears that ACT Daily may have enabled users to acquire, strengthen, and potentially generalize useful ACT skills. It is theorized that the app facilitated in-the-moment learning of skills that could then be applied directly to real-world contexts. Future research is advised to target larger, more diverse samples, implement a randomized controlled trial design, add objective behavioral and physiological measures, incorporate all six ACT processes, and integrate client feedback into future iterations of ACT Daily.

In order to decrease teachers’ decisions of which vocabulary the focus of the instruction should be upon, a recent line of research argues that pedagogically-prepared word lists may offer the most efficient order of learning vocabulary with an optimized context for instruction in each of four K-12 content areas (math, science, social studies, and language arts) through providing English Language Learners (ELLs) with the most frequent words in each area. Educators and school experts have acknowledged the need for developing new materials, including computerized enhanced texts and effective strategies aimed at improving ELLs’ mastery of academic and STEM-related lexicon. Not all words in a language are equal in their role in comprehending the language and expressing ideas or thoughts. For this study, I used a corpus-driven approach which is operationalized by applying a text analysis method. For the purpose of this research study, I made two corpora, Teacher’s U.S. Corpus (TUSC) and Science and Math Academic Corpus for Kids (SMACK) with a focus on word lemma rather than inflectional and derivational variants of word families. To create the corpora, I collected and analyzed a total of 122 textbooks used commonly in the states of Florida and California. Recruiting, scanning and converting of textbooks had been carried out over a period of more than two years from October 2014 to March 2017. In total, this school corpus contains 10,519,639 running words and 16,344 lemmas saved in 16,315 word document pages. From the corpora, I developed six word lists, namely three frequency-based word lists (high-, mid-, and low-frequency), academic and STEM-related word lists, and essential word list (EWL). I then applied the word lists as the database and developed a mobile app, Vocabulary in Reading Study – VIRS, (available on App Store, Android and Google Play) alongside a website (www.myvirs.com). Also, I developed a new K-12 dictionary which targets the vocabulary needs of ELLs in K-12 context. This is a frequency-based dictionary which categorizes words into three groups of high, medium and low frequency words as well as two separate sections for academic and STEM words. The dictionary has 16,500 lemmas with derivational and inflectional forms.

Indiana University-Purdue University Indianapolis (IUPUI) / Medication nonadherence among middle-aged to older adults with chronic conditions often stems from forgetting to take or fill medications as prescribed. A pilot study indicated the feasibility of technology acceptance model (TAM)-based smartphone medication reminder app (SMRA) training as a way to promote their app use and medication adherence. This dissertation assesses the viability and effect size of the modified TAM-based SMRA training in promoting app use and medication adherence, as well as its delivery design in preparation for a larger efficacy study. A two-group pretest-posttest design was employed. Twenty-nine adults aged over 40 years and taking medications for chronic condition management were recruited from Midwestern university and community sites. The training group (n = 15) received the modified TAM-based SMRA training; whereas the non-training group (n = 14) self-navigated app features. The training group reported significantly higher levels of perceived usefulness, perceived ease of use, positive subjective norm, and intention to use the app. In addition, the training group reported a higher proportion of active app use than the non-training group. Modified TAM-based SMRA training was not viable in increasing the levels of medication adherence variables. Effect sizes suggested at least 52 participants as a sample size for a larger efficacy study. Participants suggested that training could be improved by scheduling separate group training for iPhone and Android phone users, providing a live online training option, providing small group training with peer helper, tailoring training length to participant preference, and working with family members and healthcare providers as co-trainees and co-trainers.

Everyday one hears about another cyber attack against a company or state. In 2023 the cost of cyber crime reached 8 trillion USD and is expected to reach 10 trillion in 2025 [1]. It is becoming increasingly clear that cyber security is important in modern society and especially in the IT industry. Practical cyber security courses, like ethical hacking, are important to teach students about how attacks are performed and how to identify vulnerabilities. One such course is ethical hacking (EN2720) at the KTH Royal Institute of Technology. This practical course allows students to practice hacking techniques on a simulated corporate network much like in a capture the flag type event. However, as these networks are being used in unintended ways, as is the nature of the course, it is common for hosts in the network to break. When this happens students will email teaching assistants (TA) to restart the instance. This wastes both students time as they much wait for TAs to read their email and it wastes TAs time as they most issues they deal with are these requests for restarts. This thesis aims to research, design and implement a solution to this problem. In the research phase it is decided that the best solution would be a web application where students can authenticate themselves using existing credentials and request a restart of an instance. The design phase outlines the steps of exactly how this web app will work. The web app is implemented in python as a proof of concept and tests are written to ensure it operated as intended. It is found that the web app successfully solves the outlined problem but there could be some improvements made. Students use provided public key certificates to authenticate themselves, although appropriate in practice, it theory public keys are not secure and can be held by anyone. / Varje dag hör man om en annan cyberattack mot ett företag eller en stat. År 2023 nådde kostnaden för cyberbrottslighet 8 biljoner USD och förväntas uppgå till 10 biljoner år 2025 [1]. Det blir allt tydligare att cybersäkerhet är viktigt i det moderna samhället och särskilt inom IT-branschen. Praktiska cybersäkerhetskurser, som etisk hacking, är viktiga för att lära eleverna om hur attacker utförs och hur man identifierar sårbarheter. En sådan kurs är etisk hacking (EN2720) vid Kungliga Tekniska högskolan. Denna praktiska kurs låter eleverna öva hackingtekniker på ett simulerat företagsnätverk ungefär som i en capture the flag type-händelse. Men eftersom dessa nätverk används på oavsiktliga sätt, vilket är kursens natur, är det vanligt att värdar i nätverket går sönder. När detta händer kommer eleverna att skicka e-post till lärarassistenter (TA) för att starta om instansen. Detta slösar både elevernas tid eftersom de väntar mycket på att TAs ska läsa deras e-post och det slösar TAs tid eftersom de flesta problem de hanterar är dessa förfrågningar om omstarter. Denna avhandling syftar till att undersöka, designa och implementera en lösning på detta problem. I forskningsfasen beslutas att den bästa lösningen skulle vara en webbapplikation där studenter kan autentisera sig med befintliga referenser och begära omstart av en instans. Designfasen beskriver stegen för exakt hur denna webbapp kommer att fungera. Webbappen är implementerad i python som ett proof of concept och tester skrivs för att säkerställa att den fungerar som avsett. Det har visat sig att webbappen framgångsrikt löser det skisserade problemet men det kan göras några förbättringar. Studenter använder tillhandahållna offentliga nyckelcertifikat för att autentisera sig själva, även om det är lämpligt i praktiken, är offentliga nycklar enligt teorin inte säkra och kan innehas av vem som helst.

Health and fitness apps have become ubiquitous as smart devices become a major necessity in day-to-day life. However, an obvious issue with mobile health (mHealth) apps is that a substantial portion of them lack a scientific foundation and instead utilize  experiential  stratagems.  Hence,  the  acquired  data  becomes  unreliable.  In sports, where data collection is extensive, this becomes a vital factor for success due to  the  increasing  usage  of  mHealth.  Therefore,  the  Swedish  School  of  Sport  and Health Sciences has, in collaboration with other organizations, created the Perceived Load  and  Fitness  Scale  Questionnaire.  The  purpose  of  this  questionnaire  is  to function as a marker for overtraining, and thus injury prevention and intervention will become a simpler and more efficient task. A computer software was developed for the questionnaire; however, a mobile version was required, and thus requested. Consequently, the mHealth prototype app eValuate was developed. Research, in the form of literature studies, and dissection of other apps, for additional information, contributed  to  the  development  of  it.  The  prototype  was  developed  using  the programming language Java with Android Studio as the Integrated Development Environment  and  Cloud  Firebase  Firestore  as  a  database  solution.  The  finished prototype, eValuate, had to be trialled to ensure that it satisfies the criteria. Thus, the Mobile Application Rating Scale was employed as the most appropriate means of evaluation. A small-scale study was planned to trial the prototype by utilizing this scale.  However,  due  to  unforeseen  events,  only  four  respondents  could  provide feedback. The prototype performed admirably and scored 3.8 stars out of 5 stars. Nonetheless, the testing sample is too small to draw any real conclusions.
