CASE: a framework for computer supported outbreak detection
Baki Cakici, Kenneth Hebing, Maria Grünewald, Paul Saretok, Anette Hulth
BMC Medical Informatics and Decision Making , 2010, DOI: 10.1186/1472-6947-10-14
Abstract: Based on case information, such as diagnosis and date, different statistical algorithms for detecting outbreaks can be applied, both on the disease level and the subtype level. The parameter settings for the algorithms can be configured independently for different diagnoses using the provided graphical interface. Input generators and output parsers are also provided for all supported algorithms. If an outbreak signal is detected, an email notification is sent to the persons listed as receivers for that particular disease.The framework is available as open source software, licensed under GNU General Public License Version 3. By making the code open source, we wish to encourage others to contribute to the future development of computer supported outbreak detection systems, and in particular to the development of the CASE framework.In this paper, we describe the design and implementation of a computer supported outbreak detection system called CASE (named after the protagonist of the William Gibson novel Neuromancer), or Computer Assisted Search for Epidemics. The system is currently in use at the Swedish Institute for Infectious Disease Control (SMI) and performs daily surveillance using data obtained from SmiNet [1], the national notifiable disease database in Sweden.Computer supported outbreak detection is performed in two steps:1 A statistical method is automatically applied to a collection of case reports in order to detect an unusual or unexpected number of cases for a particular disease.2 An investigation by a human expert (an epidemiologist) is performed to determine whether the detected irregularity denotes an actual outbreak.The main function of a computer supported outbreak detection system is to warn for potential outbreaks. In some cases, the system might be able to detect outbreaks earlier than human experts. Additionally, it might detect certain outbreaks that human experts would have overlooked. However, the system does not aim to replace human experts
MicroSim: Modeling the Swedish Population

Computer Science , 2009,
Abstract: This article presents a unique, large-scale and spatially explicit microsimulation model that uses official anonymized register data collected from all individuals living in Sweden. Individuals are connected to households and workplaces and represent crucial links in the Swedish social contact network. This enables significant policy experiments in the domain of epidemic outbreaks. Development of the model started in 2004 at the Swedish Institute for Infectious Disease Control (SMI) in Solna, Sweden with the goal of creating a tool for testing the effects of intervention policies. These interventions include mass vaccination, targeted vaccination, isolation and social distancing. The model was initially designed for simulating smallpox outbreaks. In 2006, it was modified to support simulations of pandemic influenza. All nine millions members of the Swedish population are represented in the model. This article is a technical description of the simulation model; the input data, the simulation engine and the basic object types.

Energy and Power Engineering (EPE) , 2010, DOI: 10.4236/epe.2010.21006
Abstract: Poly (3-hydroxy alkanoate)s, PHAs, have been very attractive as biomaterials due to their biodegradability and biocompatibility. These hydrophobic natural polyesters, PHAs, need to have hydrophilic character particularly for drug delivery systems. In this manner, poly (ethylene glycol) (PEG) and hydrophilic functional groups such as amine, hydroxyl, carboxyl and sulfonic acid have been introduced into the PHAs in order to obtain amphiphilic polymers. This review involves in the synthesis and characterization of the amphiphilic PHAs.

Wireless Sensor Network (WSN) , 2017, DOI: 10.4236/wsn.2017.98013
Abstract: RFID technology is one of the important technologies to determine the object locations. Distances are calculated with respect to calibration curves of RSSI amplitudes. The aim of this study is to determine the 2D position of mobile objects in the indoor environment. The importance of the work is to show that localization by using Artificial Neural Network plus Kalman Filtering is more accurate than using classical KNN method. An indoor wireless sensing network is established with strategically stationed RFID transmitter nodes and a mobile object with a RFID receiver node. A fingerprint map is generated and K-Nearest Neighbourhood algorithm (KNN) is deployed to calculate the object locations. Fingerprint coordinates and RSS values received at these coordinates are deployed to set up an Artificial Neural Network (ANN). This network is used to determine the unknown object locations by using RSS values received at these locations. The accuracy of object localization is found to be better with ANN technique than KNN technique. Object coordinates, determined with ANN technique, are subjected to Kalman filtering. The results show that localization accuracies are improved and localization error distances are reduced by 46% with the deployment of ANN + Kalman Filtering.
Amphiphilic Poly(3-hydroxy alkanoate)s: Potential Candidates for Medical Applications

Abstract: Poly(3-hydroxy alkanoate)s, PHAs, have been very attractive as biomaterials due to their biodegradability and biocompatibility. These hydrophobic natural polyesters, PHAs, need to have hydrophilic character particularly for drug delivery systems. In this manner, poly(ethylene glycol) (PEG) and hydrophilic functional groups such as amine, hydroxyl, carboxyl, and sulfonic acid have been introduced into the PHAs in order to obtain amphiphilic polymers. This review involves in the synthesis and characterization of the amphiphilic PHAs. 1. Introduction Biomaterials have been widely used in medical applications, such as drug delivery, tissue engineering, device-based therapies, and medical imaging [1, 2]. Synthetic and naturally occurring polymers have played important role in the treatment of disease and the improvement of health care. Among them, PHAs are promising materials for biomedical applications in tissue engineering and drug delivery system because they are natural, renewable, biodegradable, and biocompatible thermoplastics. PHAs have been used to develop devices, including sutures, nerve repair devices, repair patches, slings, cardiovascular patches, orthopedic pins, adhesion barriers, stents, guided tissue repair/regeneration devices, articular cartilage repair devices, nerve guides, tendon repair devices, bone-marrow scaffolds, tissue engineered cardiovascular devices, and wound dressing. However the direct use of these polyesters has been hampered by their hydrophobic character and some physical shortcomings [3]. The key to biocompatibility of biomedical implantable materials is to render their surface in a way that minimizes hydrophobic interaction with the surrounding tissue. Therefore, hydrophilic groups have been introduced into the PHAs in order to obtain amphiphilic polymer. This review has been focused on the chemically modified PHAs with enhanced hydrophilic character as biomaterials for medical applications. 2. PHAs PHAs are accumulated as intracellular granules as a result of a metabolic stress upon imbalanced growth due to a limited supply of an essential nutrient and the presence of an excess of a carbon source. These novel biopolymers have material properties ranging from rigid and highly crystalline to flexible, rather amorphous and elastomeric. There have been many studies reported on the modification reactions to enhance mechanical and thermal properties to prepare new biomaterials for the medical applications [4–13]. PHAs can be classified into three groups based on the number of carbon atoms in the monomer units:
Theoretical approaches to ethnicity, nationalism and nation

Sociologija , 2006, DOI: 10.2298/soc0603231b
Abstract: The author takes into consideration main theory of ethnicity and nationalism: primordialism, perennialism, modernism, ethno-symbolism, post-modernism, and interactionism. He pays his attention on both good and bad features of the different theoretical approaches in order to formulate his own approach. In addition, he offers several the most famous and convincing definitions and typologies of the nations and nationalism. At the end, he tries to make definitions of the ethnicity (ethnical connectedness), ethnical resource, e. g. language, religion, "race", ethnic myths etc, ethnic category, and ethnic as well as to briefly outline his own approach that is basically interactionist with some additions of ethno-symbolism.

Abstract: Scientific Background: Primary degenerative dementia can show different features in the early stages and can start with asymmetric or symmetric focal degeneration. Posterior cortical atrophy is a rare progressive dementia syndrome which can be evaluated, using neuropsychological tests and neuroimaging techniques, along with clinical features. Definitive diagnosis is made histopathologically.Objective: To discuss the clinical features of a case with posterior cortical atrophy, characterized by progressive visuospatial disorder, and the differential diagnosis, under the light of related literature.Results: Neurocognitive assessment revealed a serious visuospatial and constructional disturbance as well as facial recognition defects, dressing apraxia and agraphia, and a mild memory and verbal fluency impairment. Cranial MRI demonstrated bilateral parieto-occipital atrophy, and the SPECT investigation showed decreased perfusion in the right temporoparieto occipital region compared to the left hemisphere. Routine and other laboratory investigations were normal. Conclusion: The patient was started on memantine with a daily dose of 20 mg, twice a day. After four months, he became temporarily able to drive and park his tractor, but, the symptoms progressed later. (Archives of Neuropsychiatry 2009; 46: 192-6)

Political Cartoons in 1946 Turkish Elections

Online Journal of Communication and Media Technologies , 2011,
Abstract: 1946 elections retain a different part and significance by many aspects. Certainly, 1946 elections were not the only significant election in Turkish political history. However, 1946 elections indicate a crossroad, a milestone. 1946 elections express an important stage in Turkish political history as of transition stages from Sel uklu to principalities, from principalities to Ottoman State, from Ottoman State to Republic. Therefore it is one of the most important exchanges.Transition to multiparty system can be considered not with 1946 elections, but with the establishment of National Development Party (MKP). As a matter of fact, two distinct parties were established between 1923 and 1944; both of them were suppressed by the moderation of the council of ministers (Tuncer, 2003). On the other hand, the first party in the multiparty system period is the National Development Party, established on July 18, 1945 (MKP). As for Democrat Party (DP), it was established on January 7, 1946 following MKP (Tuncer, 2003).The significant part of 1946 elections with regards to this study of ours is that, it must be rather hard to decide electing the party to govern the country, for a mass, which was unaware of even imagining what the authority of electing one out of multiple until that day. At this point the role of mass media had been extensive in addition to messages received directly and via threshold level through face to face communication.
