Remote sensing plays a vital role in analyzing urban changes. In this regard, various datasets collected from satellites today serve as a foundation for decision-makers and urban planners. This study compares the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Built-up Index (NDBI) as indicators for the creation of surface heat islands. Using Landsat 8 OLI/TIRS C2 L2 images, spatial correlations between land surface temperature (LST) were examined for August 2013, 2019 and 2023. Urban heat islands (UHI) are a contemporary phenomenon and increasingly common in large urban areas compared to surrounding, less populated areas. With the advancement in remote sensing, it is possible to adequately determine the spatial differentiation and prevalence of urban heat islands (UHI). The study is based on Landsat 8 satellite image sets for the Sarajevo basin in August 2013, 2019 and 2023, which were used to analyze LST, NDVI, and NDBI indices. This work indicates a relationship between LST and NDVI but varies depending on the analyzed year. Normalized Difference Built-up Index (NDBI) serves as a suitable indicator for surface UHI effects and can be used as an indicator to assess its spatial distribution within a larger urban environment.

The global trend of incorporating students with disabilities into mainstream education is on the rise, a phenomenon observed in countries like Macedonia and Bosnia and Herzegovina. However, the attitudes of parents with typically developing children play a pivotal role in shaping the educational journey of students with special needs within regular school systems. This study aims to delve into the level of sensitization among parents of typically developing students concerning their peers with diverse developmental disabilities in Macedonia and Bosnia and Herzegovina. Data for this investigation were collected through a survey comprising 10 questions, each offering 3/4 possible responses. The sample size includes 90 parents of typically developing students attending regular schools across North Macedonia and Bosnia and Herzegovina. Thematic analysis of survey results unveils challenges and barriers in the inclusive education process, shedding light on parental sensitization. This exploration identifies specific issues and proposes potential solutions to enhance the inclusivity of the education system. The identified issues emphasize the necessity for targeted interventions and proactive measures to raise awareness among parents, fostering a more supportive and inclusive educational environment. By suggesting plausible solutions, this study contributes to the ongoing discourse on inclusive education, serving as a foundation for further research and practical initiatives.

Background: Radical surgical resection for pancreatic head carcinoma offers a chance for cure but unfortunately is only available to a limited number of patients. For a significant number of patients, palliative surgery remains the only option. The question of the most effective approach for patients with borderline resectable pancreatic head carcinoma (BRPHC) remains unresolved. Objective: The aim of the study was to compare the morbidity and mortality following R1 duodenocephalic pancreatectomy and double palliative bypass to explore the most optimal surgical treatment for patients with BRPHC. Methods: Our retrospective cohort study included 64 patients with BRPHC who underwent surgery from 2012 to 2019, with postoperative follow-up for three years. Morbidity and mortality parameters were examined based on the type of surgical treatment: R1 duodenocephalic pancreatectomy or palliative double bypass. Chi-square test, univariate regression, and Kaplan-Meier analysis were used as basic statistical methods in the analysis of the results. Results: Patients undergoing R1 duodenocephalic pancreatectomy had a 3.69 times higher risk of developing biliary leak (p=0.039; 95%CI:1.066, 1.181) and shorter survival compared to those undergoing palliative double bypass (p=0.022). No statistically significant association was found between the type of surgical procedure and other postoperative complications. Conclusion: Our study suggests that the double palliative bypass procedure may be a better option than R1 resection for patients with BRPHC.

Background: Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related deaths worldwide. Studies often consider colon and rectal cancers together. The combination of CA 19-9 and CEA markers is used to improve diagnostic accuracy, but there are no reports on the use of this combination as a prognostic predictor for CRC. The study by Kamada et al. was the first to use the "tumor marker index" (TMI), the geometric mean of normalized CEA and CA 19-9 in CRC, demonstrating the prognostic capabilities of this novel marker. However, it is not known how the preoperative value of TMI compares and fits into the current system of prognostic factors for preoperative prediction of overall survival (OS) and disease-free survival (DFS). Objective: The aim was to investigate the significance of preoperatively determined TMI in predicting three-year overall survival (3Y-OS) and three-year disease-free survival (3Y-DFS) in patients with stage III adenocarcinoma of the upper and middle rectum. Methods: Our retrospective cohort study included 93 patients who underwent open anterior resection of the rectum between January 2015 and December 2020. Optimal cut-off values of the markers were determined by ROC analysis. Statistical analysis was performed using IBM SPSS Statistics 22 and R 4.4.0. Results: Patients with TMI ≥1.0158 had a statistically significantly higher likelihood of mortality within three years (p=0.012). Patients with TMI ≥0.979 had a statistically significantly higher likelihood of disease-free survival of less than three years (p=0.003). Compared to CEA and CA 19-9, TMI had the highest AUC for predicting 3Y-OS (0.740, p=0.020) and 3Y-DFS (0.780, p=0.012). Adding TMI to other predictors increased the AUC for predicting both 3Y-OS (from 0.748 to 0.853) (p=0.001) and 3Y-DFS (from 0.711 to 0.850) (p=0.001). Conclusion: Our study confirmed previous findings on the usefulness of preoperative TMI as a prognostic marker, further expanding knowledge about its accuracy by comparing and combining it with established prognostic factors, including CEA and CA 19-9.

Background: Human papillomavirus is a risk factor in the development of cervical cancer. Other risk factors are frequent vaginal infections, cigarette smoking, use of oral contraceptives, but also lack of lacrobacillus in women with HPV infection. Objective: The objective of our study was to determine the risk factors for the development of cervical intraepithelial lesions in women with normal and pathological Pap test results. Methods: The research is a prospective study conducted in the Gynecology Center "Dr. Mahira Jahić" Tuzla and Dom Zdravlja Tešanj since February. 2023 to March 2024. The research included 200 respondents aged 25 to 50. Tested group: 100 subjects with pathological Pap smear findings (ASCUS, LSIL and HSIL) and a control group of 100 subjects with normal Pap smear findings. Sociodemographic data were obtained from the subjects during interviews and examinations: age, cigarette consumption and frequency of previous vaginal infections and the presence of lactobacilli. The obtained results were processed using the methods of descriptive statistics, student's t test and X2 test. A difference for a value of p<0.5 was considered statistically significant. Results: The mean age of the dpbo examined group was 38.1±1.7, while in the control group it was 39.6±1.9 years. Cigarettes were consumed by 62 (31%), 38 (19%) of the examined group, and 24 (12%) of the control group with a statistically significant difference of p<0.05. Out of a total of 100 in the examined group, 60 subjects had LSIL, 9 subjects had HSIL (CIN 2 two subjects and CIN 3 had 7), and ASCUS 29 and ASC-H 2 subjects. Subjects with pathological findings had significantly more vaginal infections during one year (p<0.05). HPV was positive in 65 (65%) subjects with a pathological Pap smear test, and negative HPV in 35 (35%). HPV 16,18 was present in 19 (19%) test subjects in combined form, and mono-isolate HPV 16 in 14 (14%) and HPV 18 in one case. In the combined form of several HPVs, HPV 16 and HPV 31, 33, 35, 45, 56 were found in 5 (5%), and HPV 18 in 4 (4%) with HPV 36, 59, 68. The most frequently isolated HPV 16 in 38 (38%) as monoisolate and in combined form. Lactobacilli were present in 26 (13%) subjects in the test group and in 60 (30%) subjects in the control group, with a statistically significant difference (p<0.05). The presence of Lactobacillus in subjects with a regular Pap test is significantly more frequent compared to women with cervical intraepithelial lesions (ASCUS, LSIL, ASC-H and HSIL) ) in the finding of the Pap test. Conclusion: Altered microflora of the vagina, lack of lactobacilli, frequent vaginal infections and smoking are risk factors for the development of CIN lesions in women positive for high-risk HPV.

In this work, the solubility of creatine, creatinine, guanidinoacetic acid, and their hydrochlorides in water at atmospheric pressure and in the temperature range T = (293.15 - 313.15) K was determined by the gravimetric method. The thermodynamic parameters of dissolution in water for the mentioned compounds were calculated. The solubility increases significantly by converting the zwitterionic structures of creatine and guanidinoacetic acid into a cationic form, i.e. hydrochloride salt. The effect of increasing solubility is more pronounced for guanidinoacetic acid and decreases with temperature for both compounds. A simple process of transforming electrically neutral zwitterionic structures into cations represents a good way to increase the solubility in water and bioavailability of biologically active compounds.

Background: Launois-Bensaude syndrome is a rare condition characterized by the accumulation of fat deposits under the skin. This disorder is most commonly found in individuals from Mediterranean countries, particularly those who are chronic alcohol consumers. The exact cause of this syndrome is still not fully understood. Objective: Launois-Bensaude syndrome, as the case of the patient with chronic hepatitis B infection we presented. Case report: A case study was conducted on a female patient admitted to the Clinic for Plastic and Reconstructive Surgery at the Clinical Centre University of Sarajevo. The patient underwent liposuction in the back of her neck after a thorough clinical examination and radiological assessment. She also had chronic hepatitis B virus infection along with other medical conditions. Discussion: Based on Schiltz's classification, the patient was diagnosed with type Ia Launois-Bensaude syndrome, which is characterized by fatty deposits in the neck region, often referred to as a "buffalo hump". Following the liposuction procedure, the patient was monitored for 2 years and did not experience a recurrence of the disease. Conclusion: Research suggests that liver disease plays a crucial role in the development of Launois-Bensaude syndrome. This highlights the importance of understanding the pathophysiological mechanisms underlying this rare disorder.

Background: World Health Organization (WHO) defines human resource pl anning in the healthcare industry as "The process of estimating the number of people, knowledge, skills, and attitudes needed to achieve a set of goals".Human resource planning is the most important part of the work of organizational management. Objective: The aim of the study was to point out the importance of timely and optimal planning of human resources and their impact on the work efficiency of healthcare professionals. Methods: This research is a comparative, descriptive-analytical study which used a questionnaire created according to the Likert model. The questionnaire containes statements related to factors affecting work efficiency, work analysis, position systematization, human resource planning, professional selection, work process design, management and manager's style, etc. Results and Discussion: A total of 450 respondents (healthcare professionals, both docotrs and nurses) participated in this research. Participation (inclusion) critaria in the research is employment in healthcare institutions in Canton Sarajevo, of different ages, of both genders. The planning process begins with a quality job analysis and human resource analysis to get an answer to several very important questions. How many people are needed to realize the set goals of the organization? What kind of people are needed: what skills, knowledge, and abilities? How to attract the necessary people (internal, external filling, selection procedure). How to adjust the current employee’s training so that they can adequately respond to all work tasks in the future, more demanding business environment of the health organization? The lack of human resources that have the necessary skills and knowledge, and the burden of inadequate resources (disabled workers), have slowed down the development of many companies. We are experiencing significant negative manifestation on the existing staff through reduced work efficiency and reduced quality of health care provided. Due to the above, it is necessary to timely plan human resources as an integral part of planning, business, and development of the entire organization. The planning of human resources in a health institution is influenced by the following factors: a) institutional factors b) level of health care c) type of health care institutiond) size of health care institution e) infrastructure of the existing institution. Conclusion: Human resource planning is a fundamental management activity from which all other activities arise,and contents of human resource management planes are based.

This article describes the architecture life cycle effect analysis (ALCEA) method, a structured method for evaluating proposed new architectures for software-intensive systems. The method evaluates a proposed architecture by quantifying its effect on the performance of system life-cycle phases. The method is instantiated by identifying the relevant life-cycle phases of the system under investigation and a set of evaluation functions that capture, in terms of basic factors, the effect of different architectural decisions on key life-cycle PAs, such as revenue, operating resources, and investments. The method results in a transparent cost and revenue structure, documented in a tabular form, based on quantifiable factors from the developing organization. The results of the method can be used directly as part of a business case, and their robustness can be estimated by sensitivity analysis. The ALCEA method is designed for system-level architectural analysis, covering both software and hardware aspects. In this article, we introduce the ALCEA method and provide a detailed example of how to apply it in the evolution of embedded systems. Moreover, we share early experiences of using the method in large-scale industrial settings.

Large peak-to-average power ratio (PAPR) and carrier frequency offset (CFO) are dominant impairments of the orthogonal frequency-division multiplexing (OFDM) symbol transmission that is applied within the state-of-the-art wireless operator networks. In this work, we deal with consequences of the amplitude peak clipping that is commonly used at the transmitter to reduce the PAPR of the OFDM symbol, and thus prevent its non-linear distortion which would otherwise be imposed by the output high-power amplifier (HPA). Accordingly, regardless of the clipping generating mechanism at the transmitter being either inherent (related to the HPA) or deliberate (due to PAPR reduction), the clipped incoming OFDM symbol at the receiver may lead to degraded detection accuracy and transmission performance. However, the methods that have been applied so far at the receiver for compensating non-linear distortion due to clipping, are quite complex and computationally demanding. On the contrary, we propose effective mitigation of the problem to be performed at the receiver, by deriving the closed-form enhanced detection criterion, which requires common measurements of the mean and the rms values, as well as the autocorrelation of the received OFDM symbol comprising both un-clipped and clipped sections. Such improved detection was shown to significantly reduce the side effects of clipping, and restore satisfactory transmission performance – the bit error rate (BER) in particular. The proposed analytical model was preliminarily verified by versatile Monte-Carlo simulations and professional industry-standard vector signal analysis (VSA) test system, as well as by BER testing. The evident convergence of the three methods’ test results leads to the conclusion that the proposed clipped OFDM symbol detection method provides clear improvement with respect to the conventional one.

Every attempt to access to the Internet through a Web browser, email sent, VPN connection, VoIP call, instant message or other use of telecommunications systems involves cryptographic techniques. The most commonly applied technique is asymmetric cryptography, which is generally executed in the background without the user even being aware. It establishes a cryptographic code based on the computational complexity of mathematical problems. However, this type of cryptography, which is widely used in today’s telecommunications systems, is under threat as electronics and computing rapidly develop. The development of fifth-generation cellular networks (5G) is gaining momentum, and given its wide field of application, security requires special attention. This is especially true faced with the development of quantum computers. One solution to this security challenge is to use more advanced techniques to establish cryptographic keys that are not susceptible to attack. An essential part of quantum cryptography, Quantum Key Distribution (QKD) uses the principles of quantum physics to establish and distribute symmetric cryptographic keys between two geographically distant users. QKD establishes information-theoretically secure cryptographic keys that are resistant to eavesdropping when they are created. In this paper, we survey the security challenges and approaches in 5G networks concerning network protocols, interfaces and management organizations. We begin by examining the fundamentals of QKD and discuss the creation of QKD networks and their applications. We then outline QKD network architecture and its components and standards, following with a summary of QKD and post-quantum key distribution techniques and approaches for its integration into existing security frameworks such as VPNs (IPsec and MACsec). We also discuss the requirements, architecture and methods for implementing the FPGA-based encryptors needed to execute cryptographic algorithms with security keys. We discuss the performance and technologies of post-quantum cryptography, and finally, examine reported 5G demonstrations which have used quantum technologies, highlighting future research directions.
