Luigj Gurakuqi University of Shkoder
Shkoder, Albania

The University of Shkodër "Luigj Gurakuqi" in Albania was established in 1957.It has 6 faculties, 15 branches, 14 departments and more than 140 professors. It has been the major institution of higher education in the region, especially in the technical and scientific disciplines. In 1992, the university received permission from the government to initiate the development of the Faculty of Economics, with responsibilities for emphasizing market economics, management, and business administration. Menduh Derguti, rector of the University of Shkodra in 1992, asked the University of Nebraska–Lincoln to help develop its curriculum in market economics and business management. Derguti attended training seminars provided by the UNL team in September 1992. As a result, the rector, Dr. Gjovalin Kolombi, established the Faculty of Economics.In 2002, the university received permission from the government to initiate computer science courses. The courses are being helped by HAN University, Netherlands.The university has the Luigj Gurakuqi University Library. Wikipedia.

This paper demonstrates an e-medical test recommendation system based on the analysis of patients’ symptoms and anamneses. The exact test selection for a specific patient can be time consuming and error-prone due to the huge amount of information to be considered like: the number of tests, patients, long working hours, exceptional cases, etc. The redundant or missing tests can cause serious loss of money, time and more seriously delay in the initiation of the therapy. The study aims to provide a fast and cost effective system for the medical experts and patients. The data are collected from the patient records of a private hospital, preserving anonymity, from all departments. Only the internal medicine department data are utilized. The patients’ age, gender and the words used in the anamneses and symptoms as plain text are the input for the system. The texts are analyzed and various methods have been applied for selecting the effective words for recommending a specific medical test. These terms, along with the demographic information, are used as the features of the well-known machine learning algorithms of WEKA [5], namely Sequential Minimal Optimization (SMO), J48, Random-Forest (RF), Bagging (Bagg), ADTree (ADT) and AdaBoostMl (ABoost). The number of medical tests that are applicable in the hospitals is too high, therefore only 20 most frequently required ones are selected. The promising results of the study indicated that the symptoms given as plain text can be efficiently utilized by the experts for medical test selection. © Springer Nature Singapore Pte Ltd. 2017.

Measuring the customer satisfaction is one of the most important aspects for every successful enterprise trying to improve its service quality, so accumulating reviews is highly encouraged. However, as the number of reviews expand it is crucial to develop effective sentiment analysis systems capable of classifying the comments to accomplish further analysis. This is one of the rare studies analyzing health service contentment, especially in Turkish. Positive and negative comments collected from patients were used to train and test a classification system by using machine learning methods such as Naïve Bayes, Support Vector Machine (SMO) and J48 tree algorithms, resulting in instantaneous and high average prediction rates varying between 90.4% to 95.8%. © Springer Nature Singapore Pte Ltd. 2017.

The aim of this work was to identify the newly discovered population of Knipowitschia from southern Albania using molecular methods. Samples were collected from the Butrint Lagoon catchment with seine nets. Mitochondrial cytochrome b and nuclear ribosomal protein gene (S7) were analyzed. A nuclear marker was used for the first time to study relationships between and among Knipowitschia species. The results show that the population from Albania belongs to Knipowitschia goerneri Ahnelt, 1991 (Corfu dwarf goby), a species previously thought to be endemic to the Korission Lagoon catchment on Kerkyra Island, Greece. Based on both mitochondrial and nuclear markers, this species was recovered in a well-supported Ionian clade also comprising Knipowitschia milleri (Ahnelt & Bianco, 1990) (Acheron spring goby) from the Acheron River and the Knipowitschia population from Trichonis Lake. © 2017 Blackwell Verlag GmbH.

The evaluation of the trophic state of the Shkodra lake was studied regarding to the Hakanson classification based on chlorophyll a (mg/m 3 or mg/dm3) and regarding to the Index of Carlson (TSI), based on phosphorus content in water (mg/m3 or mg/dm3). This was the main aim of the study and its results were reported. The (TSI) of Carlson uses the algae biomass to classify the trophic state. Also during our work have been determined the water quality based on water temperature, pH, turbidity, ion content, difference in ionic content between different stations of sampling, and metal content in water and sediments of the lake, as well. It was shown that the trophic state of the Shkodra lake, independently of the sampling sites location, is inside the oligotrophic area; the quality of water is considered good and there is no pollution of water and sediments by heavy metals.

We introduce rrecsys, an open source extension package in R for rapid prototyping and intuitive assessment of recommender system algorithms. As the only currently available R package for recommender algorithms (recommenderlab) did not include popular algorithm implementations such as matrix factorization or One-class Collaborative Filtering algorithms we developed rrecsys as an easily accessible tool that can, for instance, be employed for interactive demonstrations when teaching. This package replicates state-of-the-art Collaborative Filtering algorithms for rating and binary data and we compare results with the Java-based LensKit implementation and recommederlab for the purpose of benchmarking the implementation. Therefore this work can also be seen as a contribution in the context of replication of algorithm implementations and reproduction of evaluation results. Copyright held by the author(s).

The objective of this study was to determine and compare levels of heavy metals in the leaves of Plantago major and the soil near the root zone. The study was conducted in the region of Durrës city, in Albania. The metals studied in this work were Pb, Cu, Zn, Mn, and Ni. Heavy metals presented in leaves of plants and soil have been detected using an atomic absorber spectrophotometer model NovAA400 (Analitik Jena). The results show that the determined metals were present in the soil and leaves of Plantago major. The concentrations of metals found in soil change in the order Zn>Pb>Ni>Mn>Cu. The highest concentration was found for Zn and Pb. In our study, results showed a good correlation between Pb and Zn in the soil, suggesting the same origin of pollution. Plantago major showed the ability to absorb metals and the concentration of metals in leaves showed a good correlation with the concentration of metals in soil.

This paper analyzes the spatial transformations that occurred in the peri-urban area of Shkodër city after 1990, particularly the "Rrethinat" commune, which has experienced the most dramatic social, economic and land use transformations in the Shkodra region during this period, along with Shkodër city itself. This is the first study undertaken for this area and it aims to examine the causes, the dynamics and the impact of these transformations on the community and on land use. Using a problem-resolving (applied) approach, the study finds that the most immediate problems that need to be addressed are: the lack of an administrative identity for this area, the high degree of economic, demographic and settlement informality and the lack of an adequate public infrastructure. It concludes by emphasizing the necessity to develop and carry out a general regulatory plan for this territory, as the final solution to all the above-mentioned problems, and as a way to achieve sustainable development.

This study was developed believing that geographic search technology is the future of research methodology. Due to the importance of geographical environment in the routine issues, the close connection between spatial extension and most of the phenomena running over the world, the geographic query process turns to be key factor in overcoming hazard decision-making and evaluation. Spatial research differs in that it requires a combination of text and geographical data. To find the right formula we need to adapt the search algorithm to the application needs. We take note the Earth is nearly spherical (ignoring ellipsoidal effects) so great-circle distance formulas give the distance between points on the surface of the Earth correct to within 0.5% or so [5]. According to the search range and the search limit we induce to introduce the Cosine algorithm who better fulfill the two basic requirements, speed performance and data retrieval accuracy. © 2015 IEEE.

An evaluation of the biological status of the lake Shkodra and the Buna river in accordance with Annex V of Water Framework Directive is given. The investigation is based on the results of the last 3-year field monitoring and different publications. The main criteria used are: biological elements as chlorophyll a, microalgae (phytoplankton and phytobenthos), aquatic and wet land macrophytes, benthic invertebrates and fishes. Also, some hydromorphological elements (water level fluctuation, water flow, substratum), climatic elements (mean water temperature) and physicochemical elements (Sechi disc, conductivity, pH, dissolved oxygen content and nutrient loads) are used to clarify the biological condition. According to biological elements values, the ecological status of the Shkodra lake and the Buna river can be classified as good to moderate. The destruction and disturbance of the natural habitats by flooding and intensive human activities, as the discharge of untreated sewage waters and wastewater into lake and river, the occupation of a large surface by invasive plant species, introduced of aggressive fish species and decrease of populations of consumed fish species showed for disturbed conditions of the both water ecosystems.
