The aim of this paper was to compare two business models, namely business to business and business to customer. The first model is oriented towards the delivery of intermediate goods ordered by an immense foreign market leader that is outsourcing a part of its business. The second model is consumers oriented and is more about innovation and the creation of goods ready to be immediately sold on the market. Bosnia is a developing country, and often a place for establishing B2B businesses. However, we are lacking in innovation, our own know-how, and the creation of challenging business opportunities. It also faces the problem of brain drain; therefore, it is in a need of a plan for retaining the youth within the country. The analysis aimed to show how the boosting jobs and living standards in Bosnia, are affected by the investments, exports, and salaries within the B2B and B2C companies. The results showed that Bosnia has a significant potential for raising living standards, employment and salary, if investments are directed towards innovations, knowledge-intensive and B2C businesses instead of labor-intensive investments.

The mountain rescue services in Croatia and BiH have been using UAVs on search and rescue missions for years. They prove to be very effective on the hard-to-reach Mediterranean karsts landscape, characterized by low but not too dense vegetation. After mapping some terrain segment and collecting a large number of precise and detailed footage from above, images are visually scanned and examined by search rescue member/s. In this paper we will examine the effectiveness of visual search of human observers for the purpose of finding missing/lost persons on aerial imagery.

An indoor terrarium population of Amblyomma geoemydae was established subsequent to the import of a single yellow‐marginated box turtle Cuora flavomarginata. This indoor tick population revealed an unexpected resistance against de‐ticking trials, with persistence between 2010 and 2015, when the ticks were successfully eliminated. Ticks were collected from the bodies and shells of turtles, as well as from terraria soil. Species diagnosis of ticks was carried out according to distinguishable morphological characters and supported by molecular analysis using DNA‐barcoding. Introduced exotic ticks are potential vectors of pathogens and can have an impact on wildlife, domestic animals and the human population. This case emphasizes the need for sharp surveillance and control measures on imported reptiles.

The sentinel lymph node (SLN) biopsy is a highly accurate staging procedure and the most important prognostic factor in melanoma patients. The European Organisation for Research and Treatment of Cancer (EORTC) Melanoma Group aimed to design an updated evolved SLN protocol for the histopathological workup and reporting. We herein recommend extending the distance between steps according to the short axis dimension of the lymph node and optimise both conventional sectioning and staining procedures including immunohistochemistry. We also provide guidance on the description of the spatial localisation of melanoma deposits in a SLN. The histopathological features to be reported include the following: presence or absence of the metastasis, the intranodal location of the metastasis (subcapsular, parenchymal, combined, extensive confluent and extensive multifocal), the number of the metastatic deposits (1, 2-5, 6-10, 11-20 and >20), the maximum dimension of the largest metastasis (indicating its site) and the presence of extracapsular extension and of naevus cells. This updated EORTC protocol is expected to clarify and simplify the existing procedures, ensuring a reasonable workload for the laboratory and for the pathologists resulting in cost saving with no loss, and possible increase, in accuracy.

Noninvasive load monitoring have been investigated by researchers for decades due to its cost-effective benefits. Upon introduction of smart meters, obtaining data about power consumption of households became easier. Numerous different techniques have been applied on the power consumption data to gain useful information out of it. This study applies machine learning techniques (Bayes network, random forest and rotational forest) to determine the operation state of households, where households are assumed to be either in ON or OFF state. Tracebase power consumption signature repository was used to train and test proposed machine learning models. Tracebase dataset was preprocessed to generate 4 different datasets. Test results have shown that these machine learning algorithms are able to estimate operation state with high accuracy and Bayes network shows outstanding performance among them with overall accuracy of 95%. Proposed method is extremely cost-effective for load monitoring and could replace some of the physical sensors in the smart houses.

Congestion control algorithms are crucial in achieving high utilization while preventing overloading the network. Over the years, many different congestion control algorithms have been developed, each trying to improve over others in specific situations. However, their interactions and co-existence has, to date, not been thoroughly evaluated, which is the focus of this paper. Through head-to-head comparisons of loss-based, delay-based and hybrid types of congestion control algorithms, we reveal that fairness in resources claimed is often not achieved, especially when flows sharing a link have different round-trip times or belong to different groups.

BACKGROUND Posttraumatic stress disorder (PTSD) is a complex stress related disorder, that follows a severe traumatic experience, characterized with an intense sense of terror, fear, and helplessness. The aim of this study is to identify associations of genetic variations within candidate genes DRD2 and DRD4 with various PTSD related phenotypes. PTSD lifetime and PTSD current subjects were analyzed separately, each of them were analyzed in a Case/Control design, as well as regarding BSI and CAPS within cases only. SUBJECTS AND METHODS 719 (487 male, 232 female) participants who had experienced war-related trauma between 1991 and 1999 in Bosnia and Hercegovina, Kosovo and Croatia were included in the study. Sociodemographic questionnaire, Clinician Administered PTSD Scale (CAPS) and the Brief Symptom Inventory (BSI) were used to collect clinical data. RESULTS The DRD2 rs1800497 variant and a variable number tandem repeat (VNTR) located in exon three of DRD4 were investigated for association with PTSD. In case control analyses we did not identify any significant associations. Within the PTSD current patients, we identified an association of DRD2 rs1800497 with BSI in the genotypic and the recessive model with the T allele as the risk allele. CONCLUSION Our findings suggest that rs1800497 of DRD2 gene is involved in pathogenesis of PTSD.

BACKGROUND Posttraumatic stress disorder (PTSD) is an anxiety disorder caused by highly traumatic experiences. The aim of this study was to investigate the influence of single nucleotide polymorphisms (SNPs) in the neuropeptide S receptor 1 (NPSR1) and the glutamate decarboxylase 1(GAD1) gene on PTSD and its psychopathological aspects among individuals affected by the Balkan wars during the 90s. SUBJECTS AND METHODS This study was conducted as part of the South Eastern Europe (SEE) study on molecular mechanisms of PTSD. It comprised 719 participants (539 males), including those with current PTSD, remitted PTSD and healthy volunteers. Psychometric evaluation was performed using the Mini International Neuropsychiatric Interview (M.I.N.I.), the Clinician Administrated PTSD Scale (CAPS) andthe Brief Symptom Inventory (BSI). We examined NPSR1 single nucleotide polymorphism (SNP) rs324981 and GAD1 variant rs3749034 genotypes. Case-control analyses were carried out using logistical regression to determine genotype differences between all patients that had either current or remitted PTSD and control individuals. To analyse the influence of the analysed SNPs on PTSD severity, we performed linear regression analyses with CAPS and BSI within each of the two patient groups separately. All of the calculations were performed for additive allelic, recessive, dominant and genotypic models. RESULTS We observed a nominally significant association for the major allele (G) of GAD1 rs3749034 with an increased risk to develop PTSD in a case control analysis in the recessive model (P=0.0315, odds ratio=0.47, SE=0.35). In contrast, a nominally significant association of the minor allele (A) with higher CAPS scores was identified within the patient group with lifetime PTSD in the dominant model (P=0.0372, β=6.29, SE=2.99). None of these results did withstand correction for multiple tests. No nominal significant results of GAD1 rs3749034 were found with regard to the intensity of psychological BSI symptoms. Case-control analyses of NPSR1 rs324981 revealed a nominally significant higher risk for homozygous T allele carriers to develop PTSD (P=0.0452) in the recessive model. On the other hand, the T allele showed a nominally significant association with higher BSI scores in patients suffering from lifetime PTSD in the recessive model (P=0.0434). Again, these results were not significant anymore after correction for multiple tests. No associations of NPSR1 rs324981 and CAPS score was identified. CONCLUSION The findings of this study provide some evidence that the NPSR1 and GAD1 polymorphisms might play a role in the development of war-related PTSD and its related psychological expressions. Further research is needed to elucidate the interactions of specific gene variants and environmental factors in the development of PTSD.

BACKGROUND Individuals who are exposed to traumatic events are at an increased risk of developing posttraumatic stress disorder (PTSD), a condition during which an individual's ability to function is impaired by emotional responses to memories of those events. The gene coding for neuropeptide Y (NPY) and the gene coding for brain-derived neurotrophic factor (BDNF) are among the number of candidate gene variants that have been identified as potential contributors to PTSD. The aim of this study was to investigate the association between NPY and BDNF and PTSD in individuals who experienced war-related trauma in the South Eastern Europe (SEE) conflicts (1991-1999). SUBJECTS AND METHODS This study included participants with current and remitted PTSD and healthy volunteers (N=719, 232 females, 487 males), who were recruited between 2013 and 2015 within the framework of the South Eastern Europe (SEE) - PTSD Study. Psychometric methods comprised the Mini International Neuropsychiatric Interview (M.I.N.I.), the Clinician Administered PTSD Scale (CAPS), and the Brief Symptom Inventory (BSI). DNA was isolated from whole blood and genotyped for NPY rs5574 via PCR - RFLP and NPY rs16147 and BDNF rs6265 using the KASP assay. RESULTS Tests for deviation from Hardy-Weinberg equilibrium showed no significant results. Analyses at the categorical level yielded no associations between the affected individuals and all three SNPs when compared to controls. Within lifetime PTSD patients, the major alleles of both NPY variants showed a nominally significant association with higher CAPS scores (p=0.007 and p=0.02, respectively). Also, the major allele of rs5574C>T was associated with higher BSI scores with a nominal significance among current PTSD patients (p=0.047). The results did not withstand a Bonferroni adjustment (α=0.002). CONCLUSION Nominally significant associations between NPY polymorphisms and PTSD susceptibility were found that did not withstand Bonferroni correction.

BACKGROUND Previous research showed inconsistent results concerning a possible association between solute carrier family 6 member 3 (SLC6A3) gene polymorphisms and dopamine symptoms of posttraumatic stress disorder (PTSD). Several studies also indicate that the myelin basic protein (MBP) gene is of importance in the etiology of several psychiatric disorders. The aim of this study was to investigate the relation of distinct SLC6A3 and MBP gene polymorphisms with PTSD and whether SLC6A3 and MBP genotypes contribute to PTSD symptom severity. SUBJECTS AND METHODS The study included 719 individuals who had experienced war trauma in the South Eastern Europe (SEE). Genotypes of variable number tandem repeat (VNTR) polymorphism within the SLC6A3 gene were assessed in 696 participants, and the single nucleotide polymorphism (SNP) rs12458282 located within the MBP gene region was genotyped in a total of 703 subjects. The Mini International Neuropsychiatric Interview, the Clinical Administrated PTSD Scale (CAPS) and Brief Symptom Inventory (BSI), were used for data collection. RESULTS No significant differences concerning the investigated SLC6A3 and MBP polymorphisms was identifiable between PTSD and non PTSD participants. Also we could not detect significant influence of these distinct SLC6A3 and MBP alleles on the severity of PTSD symptoms (CAPS) or BSI scores. However, the results of MBP rs12458282 within the patients with lifetime PTSD may point to a possible correlation of the major allele (T) with elevated CAPS scores. CONCLUSIONS Our results do not support an association of the analysed SLC6A3 and MBP gene polymorphisms with PTSD in war traumatized individuals. We found that there is a possibility for a correlation of the T allele rs12458282 within the MBP gene with higher CAPS scores in lifetime PTSD patients which would need to be tested in a sample providing more statistical power.
