Article Citation - WoS: 20Citation - Scopus: 42Information Technology Asymmetry and Gaps Between Higher Education Institutions and Industry(Informing Science Inst, 2020) Sahin, Yasar Guneri; Celikkan, UfukAim/Purpose This paper investigates the gaps between industry and academia perceptions of information technology fields, such as computer science, software engineering, and computer engineering, and it identifies areas of asymmetry between curricula and industry expectations. The study mainly focuses on the skills required of IT professionals (graduated students) and on how higher education institutes equip students for industry. Background Higher education institutes have several IT-related departments. However, it is not clear whether these departments have sufficient content to equip students with industry-related skills. Rapid advances mean that some curriculum topics are redundant before the end of a standard two- or four-year degree programs. Balancing the technical/non-technical skills and adjusting the curricula to better prepare the students for industry is a constant demand for higher education institutions. Several studies have demonstrated that a generic curriculum is inadequate to address current IT industry needs. Methodology The study involved a comprehensive survey of IT professionals and companies using a Web-based questionnaire sent directly to individual companies, academics, and employers. 64 universities and 38 companies in 24 countries were represented by the 209 participants, of whom 99 were IT professionals, 72 academics, and 38 employers. Contribution This paper is intended to guide academics in preparing dynamic curricula that can be easily adapted to current industry trends and technological developments, with content directly relevant to student's careers. In addition, the results may identify the skills that students need to secure employment and the courses that will provide skills in line with current industry trends. Findings The results indicate a lack of emphasis on personal and non-technical skills in undergraduate education compared to general computer science, software development, and coding courses. Employers' and software experts' responses emphasize that soft skills should not be ignored, and that, of these, analytical thinking and teamwork are the two most requested. Rather than a theoretical emphasis, courses should include hands-on projects. Rapid developments and innovations in information technologies demand that spiral and waterfall models are replaced with emerging software development models, such as Agile and Scrum development. Recommendations for Practitioners A multidisciplinary approach should be taken to the teaching of soft skills, such as communication, ethics, leadership, and customer relations. Establishing multiple learning tracks in IT education would equip students with specialized knowledge and skills in IT. An effective communication channel should be established between students and industry. It is also important to reduce the distance between academics and students and to provide an interactive environment for technical discussions. Enterprise level computing and Framework use provide job market advantages. Recommendations for Researchers Researchers and department heads, particularly those involved in curriculum design and accreditation, could use the results of this exemplary study to identify key topics for attention. Impact on Society Changes of various degrees are required in the current curricula in many higher education institutions to better meet student needs. Societies and technology are dynamic in nature, and information technology-related curricula in higher education institutions should be equally dynamic. Future Research Since technology (especially information technology) transforms and advances itself so rapidly, this study should be replicated t to investigate how these changes affect the gap between revised curricula and current industry expectations.Conference Object Citation - WoS: 5Citation - Scopus: 9A Platform for Context-Aware Application Development: Pcad(IEEE, 2015) Celikkan, Ufuk; Kurtel, KaanWe propose a novel software platform based on the notion of context-awareness which allows rapid and easy development of context aware applications. One of the fundamental goals of the proposed platform is extensibility, allowing the platform to react to new requirements without making fundamental and substantial changes. The Context Aware Application Development Platform-PCAD-has inspired from an operating system and modeled as a layered architecture. It exhibits a plug-and-play behavior very similar to devices and device drivers found on an operating system/kernel. The platform offers functions such as data management, notification, security and privacy as services. The platform provides a public interface to application developers in their development of context-aware applications. It covers a wide range of disparate application domains such as smart city and livestock monitoring applications.Conference Object Citation - Scopus: 1Veterinerler için Sensör Tabanli Tani Destek Sistemi: Vet-dey(CEUR-WS, 2015) Yanigli B.; Kurtel, Kaan; Çelikkan, Ufuk[No abstract available]Conference Object Citation - Scopus: 1A Smart Card Based Single Sign-On and Password Management Solution as a Browser Extension(2010) Erdem E.; Kucukkurt K.O.; Samurkas K.; Kanargi E.; Celikkan U.We describe the design and implementation of Web-Login Card, a smart card based Single Sign-On solution that relieves the users from remembering several username and passwords when authenticating themselves to various services on the internet. Due to its tamper-resistant storage for protecting authentication data and other personal information and cryptographic computation capabilities, smart card is an ideal token of choice in our implementation. Our solution is seamlessly integrated into the Firefox browser via a browser extension that allows users to authenticate themselves and easily manage personal information on the card. The browser extension is written using XUL, JavaScript and Java with LiveConnect providing the bridge between JavaScript and Java. javax.smartcardio library is used for the raw communication between the host and the smart card via APDU exchange using T=1 protocol. © 2010 IEEE.Article Citation - Scopus: 1Application of Service-Oriented Context-Aware Architecture To Laundry Management System(Natl Inst R&D Informatics-Ici, 2017) Celikkan, Ufuk; Kurtel, KaanThe laundry cleaning on an industrial scale has become a highly automated process, carried out by machines using sensors generating very detailed data. Data from these sensors allow the precise control of the laundry operation, often remotely. The combination of new machines with information technology has created a more efficient and cost effective process, enabled by software based on extensible architecture. The operations of a laundry exhibit all the properties of a context-aware system. This paper extends the authors' earlier work on context-aware laundry management architecture emphasizing business processes. In this study, we present architectural details that will aid implementers of the system in their choice of tools, techniques and technologies. In particular, a detailed account of laundry context information is presented. The proposed architectural framework used in the solution is able to monitor and autonomously manage laundry operations. The system employs a layered architecture which allows the separation of system components such as data capture, data processing and business services. An inference and a rule engine help to orchestrate system activities and transmit system status to interested parties through an interface. Tight coupling of system components are eliminated by web services.Conference Object Nfc Based Mobile Single Sign-On Solution as a Chrome Extension(SciTePress, 2014) Celikkan U.; Gelis C.We describe the design and implementation of Single Sign-On authentication solution that uses a Near Field Communication enabled mobile phone. Such a solution relieves the users from remembering multiple username and passwords when authenticating themselves to various services on the internet. Mobile phones are today's ubiquitous computing devices, used for a wide variety of purposes including authentication, tracking, medical care, entertainment and electronic payment. The primary advantage of NFC technology is that since it uses short range communication, it inherently provides another level of security, and being contactless, it is easy to use. Our solution is seamlessly integrated into the Chrome browser via a browser extension that allows users easy authentication and management personal information on the phone. The Google Chrome extension is written in JavaScript; However, this code (JavaScript) when running in a browser, cannot access the system resources of the computer due to browser security restrictions. Therefore a program written as a Java applet is implemented to run in the user's computer. This applet, injected into the current web page by the extension, provides access to NFC Reader and supplies the bridge between Java and JavaScript. The user does not need to enter any account information, because it is retrieved from the phone via NFC and automatically submitted to the web login page.Conference Object A public health information system design(2011) Şahin, Yaşar Güneri; Çelikkan, UfukThe integration of modern information technologies into health care resulted in development of public health care information systems for the purpose of aiding the medical community by providing for less error prone diagnoses and treatment of diseases. The architecture presented in this paper is an evidence-based health care information infrastructure which collects considerable amounts of reliable, evidence-based data over time from various sources, and that it classifies, interprets and makes the data readily available and accessible to the health care provider before patient consultations. Among many other goals, the proposed system's key objective and contribution is gathering Patients' Ancillary Data (PAD) and incorporating this information into the diagnosis and treatment workflow. The data from medical tests is enriched and complemented by patient ancillary data such as hereditary, residential, travel, custom, meteorological, biographical and demographical data. Automatic provisioning of PAD, another goal of the proposal, helps to diminish problems and misdiagnosis situations caused by language barriers-disorders that frequently prevent the acquisition of patient data. This attribute of the system assists physicians to shorten time for diagnosis and consultations, therefore dramatically improving quality and quantity of the physical examinations of patients. © 2011 Springer-Verlag.Master Thesis A Consolidated Approach for Building a Software Design Pattern Recommendation System(İzmir Ekonomi Üniversitesi, 2019) Bozoklar, Dilara; Çelikkan, UfukYazılım tasarım şablonları, yazılım geliştirme ve tasarımda sık karşılaşılan sorunlara standart çözümler sağlarlar. Sundukları birçok fayda arasında, yeniden kullanılabilir, genişletilebilir ve bakımı kolay yazılım sistemlerinin geliştirilmesine olanak tanıyor olmaları vardır. Tasarım şablonlarının anlaşılmasının karmaşıklığı, bu şablonlarının tasarımcılar tarafından yazılım tasarımı ve geliştirilmesine uyarlanmasını zorlaştırmaktadır. Tecrübesiz geliştiriciler için, belirli bir tasarım bağlamında doğru modeli seçmek zorlu bir görev haline gelir. Bu nedenle, tasarım şablonları öneren sistemler, özellikle tecrübesiz tasarımcılara ve geliştiricilere, tasarım problemlerinde doğru şablonu örnekleme konusunda yardımcı olabilir. Bu tezde, metin tabanlı bilgi alma, vaka bazlı öneri ve soru bazlı öneri metotlarını birleştirip, uygun bir şablon önerecek bütünleşik bir yaklaşım önerilmektedir Bahsedilen bu yaklaşımı kullanarak bir uygulama geliştirilmiştir. Bu etkileşimli bir uygulama olup, ilk önce metin tabanlı bilgi alımı ve vaka tabanlı öneriyi kullanarak otomatik olarak bir tasarım şablonu önerir. Bunu takip eden soru/cevap oturumu sayesinde sonuçlar iyileştirilir. Elde edilen sonuçlar sıralanır ve kullanıcıya sunulur. Uygulamanın etkinliği, bir tasarım deseni dersinde kullanılan çeşitli senaryolar kullanılarak test edilmiştir. Ön değerlendirmemiz, çoğu durumda doğru tasarım şablonunun ilk üçe yerleştirildiğini göstermektedir.Conference Object Citation - WoS: 11Citation - Scopus: 12Capturing Supermarket Shopper Behavior Using Smartbasket(2011) Celikkan U.; Somun G.; Kutuk U.; Gamzeli I.; Cinar E.D.; Atici I.Retail stores make marketing decisions using customer demographic and sales data to determine which customer and product group combination best contributes increased profit. Customer profile and sales data are of great help but they alone do not portray the whole picture. Tracking the location of a customer in a store and analyzing the customer shopping path and marrying the result to customer profile and sales data is of high interest for marketing for the purpose of streamlining store operations, maintaining customer royalty and increasing sales. In this paper, we propose a system for supermarkets that tracks the path of a shopping cart associated with a customer profile to understand the customer shopping behavior. The proposed system uses IR LED plates installed on the carts which are monitored by small and inexpensive in-shelf networked IP cameras. The shopping carts are equipped with a low cost input device that has a monitor to gather customer profile information. The system is integrated with the supermarket's web site to customize the overall shopping experience. The data collected is mined to find out the relationships among product placement, customer profile and product purchase decisions. The system is designed to monitor real time movements of the shopping cart. © 2011 Springer-Verlag.Article Citation - WoS: 2Citation - Scopus: 3Perceived Usefulness of Data Entry Tools in Medical Encounters: a Survey(Springer, 2013) Celikkan, Ufuk; Sahin, Yasar Guneri; Senuzun, FisunElectronic Health Records allows direct data entry and is an important factor for accurate diagnosis. However, two drawbacks of this system is the time needed to create them, which can reduce health care professional productivity, and the fact that it is error prone. It is important, therefore, to select the most appropriate methods and tools for data entry by the health care providers at the point of care in order to minimize a loss of productivity. The study aims to understand health care professionals' perceptions of the data entry process, and determine the appropriate methods, tools and functions that would facilitate the process, minimize loss of productivity and improve quality. A questionnaire which consisting of 18 basic questions (including demographic data) was posted on a web site which hosts questionnaires, on an established online community space and also mailed to health care professionals who are working in various hospitals for a duration of 10 months. Totally, 533 medical care professionals who are primarily from Turkey participated in the survey, of which 284 were medical doctors, 127 were nurses and the rest, other medical professionals. While the clear majority of participants involved in data entry use keyboard and mouse, most expressed a preference for more convenient methods, such as voice recognition or touch screen. Furthermore, physicians reported rarely spending more than 15 min for each consultation and conducting 21-30 examinations a day. The main motivation for creating an efficient direct data entry is to increase time allowed for patient examination, and to improve accuracy of diagnosis. Despite a heavy workload, health care professionals are very receptive to the idea of using a convenient data entry tool and keeping electronic patient records. Emergent data entry technologies in health sector can improve the quality of examinations, physicians' productivity and can decrease the percentage of medical misdiagnosis.
