Istraživanje zadovoljstva posjetitelja zaštićenih područja Istarske županije
Authors: Marković Suzana
Published: October 2019

Uvod:
Zaštićena
područja prirode predstavljaju krhke oaze povezanosti čovjeka s prirodom u
njezinu izvornom obliku u kojima je glavni cilj zaštita biološke, geološke i
krajobrazne raznolikosti. Zbog sve većeg socioekonomskog razvoja, s povećanjem
industrijalizacije, prometa te urbanizacije održivi turizam i briga za očuvanje
prirode tek sinergijskim djelovanjem mogu umanjiti težnje za profitom kroz
prekomjernu izgrađenost i posjećenost koja može negativno djelovati na
zaštićeno područje (degradacija staništa, onečišćenje i sl.) i time dovesti u
pitanje osnovnu svrhu postojanja.
Cilj ovog rada bio je
istražiti i analizirati stavove posjetitelja zaštićenih područja Istarske
županije o kvaliteti usluge, analizirati njihovo zadovoljstvo i lojalnost,
očekivanja i percepciju, te izračunati ECOSERV jaz. U tu svrhu izvršena je
prilagodba ljestvice mjerenja ECOSERV (Khan 2003). Upitnik se sastoji od pet
dimenzija (eko-opipljivost, povjerenje, pouzdanost, poistovjećivanje, susretljivost,
opipljivost) i 29 tvrdnji te pitanja koja se odnose na sociodemografski profil
ispitanika (dob, spol, obrazovanje, zanimanje, razlog dolaska, broj posjeta).
Uzorak i metode: Istraživanje
je provedeno na uzorku od 137 posjetitelja u sljedećim zaštićenim područjima: Nacionalni
park Brijuni, Park prirode Učka, park-šuma Šijana i Kamenjak. U
istraživanju su sudjelovali samo domaći posjetitelji. Rezultati: Rezultati deskriptivne
statističke analize pokazali su da postoji jaz između očekivane i percipirane
kvalitete usluga, što znači da ustanove nisu ispunile očekivanja svojih
posjetitelja, iako su posjetitelji ocijenili kvalitetu usluga u parkovima
prirode visokom prosječnom ocjenom.

Published: October 2019

El objetivo general del presente trabajo fue identificar las especies de peces que capturan los pescadores y el uso que le dan a las mismas en la cuenca inferior del río Luján. Para tal fin, se realizaron entrevistas semiestructuradas durante la primavera de 2015, el verano y el otoño 2016, las cuales permitieron obtener información sobre el uso que les dan los pescadores a los peces capturados. Se analizaron a lo largo de este período dos escenarios: los días de semana y los fines de semana. En la cuenca inferior del río Luján coexiste una diversidad de contextos sociales manifestados a través de sus actores: los pobladores locales y los pobladores de partidos vecinos que visitan el área. Las especies más mencionadas a lo largo de todo el estudio fueron: Pimelodus maculatus, Pimelodus albicans, Astyanax sp., Megaleporinus obtusidens y Rhamdia quelen. Los resultados obtenidos permiten plantear la importancia que tiene este territorio en la ribera del río Luján para los pobladores de la zona y de las regiones cercanas dado que los días de semana es un sitio que ofrece un espacio para realizar pesca de subsistencia mientras que los fines de semana constituye un espacio para el esparcimiento familiar.

Authors: Fox-Alvarez W. Alexander , Case J. Brad , Lewis Daniel D. , Joyce Ashley C. , Cooke Kirsten L. , Toskich Beau
Published: October 2019

OBJECTIVE

To evaluate the feasibility of ultrasound-guided, temporary, percutaneous T-fastener gastropexy (TG) and gastrostomy catheter (GC) placement for providing sustained gastric decompression in dogs with acute gastric dilatation-volvulus (GDV) and to compare findings with those of trocarization.

ANIMALS

16 dogs with GDV.

PROCEDURES

Dogs were randomly assigned to undergo gastric decompression by means of percutaneous trocarization (trocar group; n = 8) or temporary TG and GC placement (TTG+GC group; 8) with ultrasound guidance. The gastric volvulus was then surgically corrected, and the decompression sites were examined. Outcomes were compared between groups.

RESULTS

The proportion of dogs with successful decompression did not differ significantly between the TTG+GC (6/8) and trocar (7/8) groups; median procedure duration was 3.3 and 3.7 minutes, respectively. After the failed attempts in the TTG+GC group, the procedure was modified to include ultrasound guidance during T-fastener placement. The decrease in intragastric pressure by 5 minutes after trocar or GC insertion was similar between groups. For dogs in the TTG+GC group, no significant difference in intragastric pressure was identified between 5 and 60 minutes after GC insertion. Complications included inadvertent splenic or jejunal placement in 2 dogs (TTG+GC group) and malpositioned and ineffective trocar placement in 1 dog (trocar group). All dogs survived for at least 2 weeks.

CONCLUSIONS AND CLINICAL RELEVANCE

Ultrasound-guided, temporary, percutaneous TG and GC placement was safe and effective at providing sustained gastric decompression in dogs with GDV, suggesting that this technique would be ideal for dogs in which surgical delays are anticipated or unavoidable.
Closing wedge ostectomy with transfixation pin–cast stabilization for correction of angular limb deformities of the metatarsophalangeal region in four cattle
Authors: Lozier Joseph W. , Niehaus Andrew J. , Hinds C. Austin
Published: October 2019

CASE DESCRIPTION

4 calves were evaluated because of lameness and an angular limb deformity of the metatarsophalangeal region.

CLINICAL FINDINGS

3 calves (ages, 5 days, 10 days, and 1 month) had a congenital varus deformity of the metatarsophalangeal region characterized by medial subluxation of the first phalanx of digits 3 and 4 at the metatarsophalangeal joints. A 6-month-old heifer had a valgus deformity of the metatarsophalangeal region secondary to a malunion of a Salter-Harris type II fracture. The degree of deformity angulation ranged from 16° to 54° for the 4 patients.

TREATMENT AND OUTCOME

A closing wedge ostectomy with transfixation pin–cast application was performed on the affected limb of all 4 patients. The ostectomy healed with only minor complications (disuse osteopenia distal to the transfixation pins [n = 4] and cast sores [1]) that were easily resolved with no long-term adverse effects. Duration of follow-up for the 4 patients ranged from 6 to 17 months, and the owners reported satisfactory ambulation with no (n = 2) or only mild (2) residual lameness in the affected limb.

CLINICAL RELEVANCE

Results suggested that a closing wedge ostectomy with transfixation pin–cast stabilization is an alternative for management of angular limb deformities of the metatarsophalangeal region in cattle. Such treatment improved the quality of life for all 4 patients. However, 2 of the 4 patients had congenital deformities confirmed to be heritable. There are ethical concerns associated with treating animals with heritable disorders, and exhibition and breeding of such animals should be avoided.
Family-based Association Study of Killer Cell Immunoglobulin-Like Receptor Genes with Leukemia
Authors: Varbanova V. , Mihaylova S. , Naumova E. , Cotoc C. , Mihaylova A.
Published: October 2019

NK cell function is controlled by the cell expression of killer immunoglobulin-like receptors (KIRs) and their ligation with the corresponding HLA ligands. Various malignancies have been associated with certain KIRs surface cell expression and various KIR/HLA ligand combinations. Prior research using case/control study design demonstrates the role of KIR and KIR HLA ligands as genetic factor involved in tumor susceptibility. The objective of this study was to investigate the family-based association of KIRs, HLA class I ligands and KIR/ligand combinations with leukemia diagnosis in families having a leukemia diagnosed child. Sixty-seven families that met the index leukemia case criteria (acute lymphoblastic leukemia, ALL, n = 45; acute myeloid leukemia, AML, n = 13; chronic myeloid leukemia, CML, n = 9; first degree healthy relatives n = 159) were examined. Our study consisted of two phases. In Phase1 case-control study, we primarily compared patients to their healthy siblings to asses if a marker or genotype may be associated with leukemia, excluding the impact of the environment. Phase 2 consisted of a secondary family-based association study. KIR genotyping was performed by PCR-SSP method. KIR HLA ligands were defined by direct method using PCR-SSP method and/or indirect base on high resolution typing of HLA-A, -B, -C alleles. Results of phase 1 showed an increase in the frequency of KIR genotype (with a ratio = 0.57; higher frequency for inhibitory KIRs vs. activating KIRs) among leukemia patients compared to healthy siblings. Results of the phase 2 familial study observed an association between HLA-C1+/BBw4+/ABw4+ haplotype (a mediator of inhibitory signals) and leukemia. Also, we concluded that the absence of HLA-ABw4 alleles was related to leukemia development.

Authors: Lazarova M. , Zlatanova T.
Published: October 2019

The objective of the present study was to investigate the opinion of the managers working in the health system concerning their attitude towards the operations of control within the system and the impact of these operations on the activity of the health-care institutions.

Materials and Methods: From October 2016 till January 2017 using an anonymous questionnaire we studied the opinion of 407 medical doctors, medical and healthcare specialists working in various types of healthcare institutions for hospital care in Sofia and the countryside. Results: Only 1/5 of the respondents shared the opinion that the adequate control resulted in quality improvement of the provided medical caregiving, one in four (25,8%) believed that the control could raise the responsibilities of the officials with managerial titles; one in three (34,2%) shared the opinion it improved the responsibilities of the executives.

Conclusion: The new operational terms and conditions implemented in the health insurance system do not result in improving the work quality in the hospital, which allows the conclusion that by changing only the healthcare funding the desired positive changes could not be attained. The organization, management and provision of medical care should be generally revised.
Multiple Congenital Heart Abnormalities
Authors: Lazarov S. , Bogdanov G. , Nikolov R.
Published: October 2019

Congenital heart abnormalities are rare and most often occur separately. These structural and functional disorders can cause a range of diseases that vary in severity, from mild or even asymptomatic to severe and life-threatening. Occasionally these conditions could cause no symptoms in which case they are found accidentally when the patient is examined for other reasons or during autopsy. In this article we present the case of a 47-year-old male patient with triple congenital heart anomaly detected in two consecutive tests performed in pre-hospital medical care.
Takayasu Arteritis – A Systematic Review
Authors: Hrisrova D. , Marchev S.
Published: October 2019

Takayasu arteritis is a chronic, progressive, idiopathic, large-vessel vasculitis that affects the aorta, its main branches and the pulmonary arteries. It typically occurs in young Asian women but can be found in any ethnic group and in men. The disease is named after Mikito Takayasu, a Japanese ophthalmologist, who first described the arteriovenous anomalies in the retina of a patient with the disease in 1908. The etiopathogenesis is not known, but studies are being conducted regarding the immunological, infection and genetic aspects of the disease. Early during the course of the disease, inflammation of the involved arteries progresses, resulting in segmental stenosis, occlusion, dilatation and/or aneurysm. The clinical presentation of Takayasu arteritis varies depending on the blood vessels involved. Early symptoms are nonspecific, making the diagnosis difficult. Subsequently, arterial occlusions occur, producing more specific ischemic symptoms. Paucity of specific symptoms and laboratory biomarkers, as well as difficulties in assessing the disease activity and progression, make it often unrecognized at onset, and its activity is frequently underestimated. The diagnosis is usually confirmed by a combination of clinical manifestations, laboratory markers, diagnostic criteria and imaging methods. The purpose of this review is to address the current knowledge on pathogenesis, investigations, classification and management, and to emphasize the need for timely diagnosis, effective therapeutic intervention, and close monitoring of this disease.

Published: October 2019

The entrepreneurial sector can play an important role in increasing the functional complexity of the territorial systems with tourist functionality, by increasing the capacity of adapting the local economy to the changes caused by the economic crises. The study aims to analyze the dynamics of the entrepreneurial sector, for the period 2000-2016, and to identify the changes in the entrepreneurial profile, in the territorial systems with tourist functionality from Romania. To quantify this dynamics, a database was created, at the territorial administrative unit level, with the main economic indicators (number of companies, number of employees, turnover and profit). The database was also used for the development of trend matrices on the evolution of the above indicators, at the four-digit NACE code (classification of activities in the national economy), and on the evolution of the ranks held by each economic sector for the analyzed period. The result highlight the importance of the entrepreneurial sector, in the dynamics of local and regional economies of the territorial systems with tourist functionality.
Comparison of Two RUSLE Models at the Hillslope Scale in Experimental Plots in Haiyuan, Ningxia, China
Authors: Ewert Megan , Su Ye , Zhang Hu Wei
Published: October 2019

Topsoil erosion and mass soil losses from hillslopes have negatively affected water quality, vegetation health, local ecosystems, and livelihood. Studies have stated the effectiveness of vegetation in significantly reducing top-soil erosion and enhancing slope stability. This study aims to better understand the application of erosional models in Haiyuan of Ningxia, a semi-arid region of China. The study site is comprised of 20 experimental plots with 11 vegetation covers and 5 slope gradients in design, which were compared to the benchmark of bare land with each slope gradient. Meteorological data and soil hydraulic measurements were collected from 2005 to 2012, and runoff and sediment load were measured by concrete basins at the base of the slopes, which mainly occurred during the summer storms. Multi-plots provide different combinations of vegetation covers and slopes to identify the driving factors of topsoil erosion during rainfall-runoff events and to examine the threshold behavior of their inter-relationship. In order to determine which models were most applicable to this area, the results of RUSLE and CSLE were applied to the data and compared to the known results.

Authors: Siyar S. , Sami S. , Hussain F. , Hussain Z.
Published: October 2019

Interactions between plants represent an important aspect of ecology, which enables them to properly utilize the available resources in the given environment. The interactions are mediated by different mechanisms, among which allelopathy is a significant one. During allelopathic interactions, plants tend to suppress competitors plants or stimulate those which can help them adjust in the environment in a better manner. Such interactions are triggered by the release of chemical compounds termed, as allelochemicals, which have an important role in agricultural modulation. The objective of this experiment was to evaluate the allelopathic effects of leaf and bark extracts of sheesham (Dalbergia sissoo L.) on germination data of wheat (Triticum aestivum L.) cv. Auqab. Different concentrations (7 g/l, 14 g/l, and 21 g/l) of sundried leaf and bark extracts, obtained after 12, 24 and 36 h of soaking duration were tested for germination %, mean germination time (MGT), plumule and radicle length and seedling dry weight. It was observed that germination % was negatively affected by 21 g leaf and bark extract concentration at 36 h soaking duration, but not by lower concentration or soaking durations. MGT was significantly increased by leaf and bark extracts at three concentration levels, as well as soaking durations. Plumule and radicle length responded negatively to both leaf and bark extracts at higher concentration and when soaking duration was increased. Seedling dry weight was increased by 7 g leaf extracts at 36 h, but reduced by 21g at 12 and 24 h soaking durations. On the other hand, 21 g of bark extracts at 12, 24 and 36 h soaking duration resulted in significantly increased dry biomass. These results suggest negative allelopathy of Sheesham on studied germination parameters of wheat, except radicle length and dry biomass.

The goal of this study was to assess the water needs of elderberry. The investigation included elderberry plants that had been planted in land reclamation areas more than three years earlier. The water needs were evaluated for 5 agro-climatic regions of Poland. The calculations were based on the observation of meteorological conditions in the years 1981-2010 for the period from June 1 to July 31. To determine the water needs, the plant coefficient method was applied. The Blaney-Criddle formula, which was modified for Polish conditions by Żakowicz (2010), was used to calculate the reference evapotranspiration. The plant coefficients of elderberry, adapted to the reference evapotranspiration, were adjusted to Żakowicz’s method. The rainfall deficit with the probability of occurrence: N50%, N25% and N10%, was assessed in accordance with Ostromęcki’s method. The highest water needs of elderberry occurred in central-north-west (264 mm) and central-east (262 mm) Poland, while the lowest (244 mm) in the south-east region. In June, the highest total monthly water needs (119 mm) were noted for south-west Poland, whereas the lowest (107 mm) for the south-east region. In June and July, except for the central-north-west region, an upward time trend of water needs was noted throughout Poland. In June and July, the highest value (135 mm) of rainfall deficit N50% and N25% was estimated for the central-north-west region, while the highest rainfall deficit N10% (269 mm) for central-east Poland. The results of the presented research find application in the planning of irrigation treatments for elderberry in Poland.

Published: October 2019

Formalin fixation is a widely used method in histopathology that has certain limits. Formalin often leads to the degradation of DNA molecules in cancer tissues, which makes tissues unusable for molecular analysis. The other factors may also affect the quality of DNA isolated from fixed tissues. The aim of this study is to determine the impact of the incubation time and temperature on the quality of DNA molecules isolated from various healthy human tissues. The brain, lung and kidney tissues, excluded during the forensic autopsies of people who died of violent death, were fixed in phosphate-buffered formalin from 24h to two months. After the completion of the incubation period, the DNA was isolated using phenol-chloroform-isoamyl alcohol extraction method and the concentration and purity of the samples were determined spectrophotometrically. The degree of degradation of DNA was assessed by PCR reaction, by amplification of gene fragments which lengths were 150bp (GPD1) and 262bp (β-actin). The highest concentration, purity and preserved integrity of DNA were obtained from the brain samples. With prolonged tissue incubation times in formalin, the concentration and integrity of DNA decreased in all tissue samples, especially in the brain tissue, while the purity of DNA remained unchanged. Also, tissue fixation at +4°C contributed to a better quality of isolated DNA compared to DNA isolated from tissue fixed at room temperature. We can conclude that the type of human healthy tissue, temperature and the incubation time of formalin fixation have important influence on the concentration, purity and integrity of DNA during fixation of tissues excluded in the course of forensic autopsy.

Vancomycin is a tricyclic glycopeptide antibiotic, mostly used in the treatment of severe staphylococcal and enterococcal infections, especially in orthopedic surgery.

The purpose of this analysis was to develop a population pharmacokinetic (PPK) model of vancomycine in hospitalized patients with bone fractures and identify important factors which influence its clearance (CL).

A total of ninety-nine measurements of vancomycin serum concentrations were used in our population modeling. A two-compartment model was applied to describe the pharmacokinetics of vancomycin using subroutines ADVAN3 and TRANS4.

The study population included patients of both sexes, with the mean age of 62.12±14.69 years and body weight of 80.32±12.44kg. Vancomycin was administered as intravenous infusion with average daily dose of 1772.73±521.34mg. Out of twenty different factors evaluated in the study (including demographic, clinical and laboratory data), only daily dose of vancomycin (DD) and co-medication with piperacillin/tazobactam (PT) showed significant effect on clearance of vancomycin. The final model was described by the following equation: CL (l/h) = 0.03 + 0.000468 x DD + 0.675 x PT. Bootstrapping was used for validation of the final model.

In conclusion, the main causes of variability in the clearance of vancomycin among adult patients with bone fractures are daily dose of vancomycin and co-medication with piperacillin/tazobactam.

Published: October 2019

Indonesia merupakan wilayah rawan gempa, sehingga konstruksi bangunan memakai sistem penahan gaya seismik dianggap penting. Umumnya, struktur bangunan adalah beton bertulang, adapun baja penggunaan sistem special moment frames (SMF) lebih banyak dijumpai sebagai sistem penahan gaya seismik. Padahal menurut peraturan ASCE/SEI 7-10 terdapat pilihan sistem penahan gaya seismik untuk bangunan baja seperti special plate shear walls (SPSW), special truss moment frames (STMF) dan sistem khususnya lainnya. Studi ini akan memperlihatkan perbandingan perencanaan bangunan sistem SMF dan SPSW dalam mempelajari potensi penggunaan kedua sistem ini di Indonesia. Konfigurasi bentang antar kolom dipilih agar menghasilkan variasi desain bangunan sistem SMF sehingga menghasilkan struktur yang ekonomis. Dari hasil studi perbandingan perencanaan, diketahui jika konfigurasi struktur bangunan dengan panjang bentang antar kolom yang pendek, maka sistem SMF lebih ekonomis bila dibandingkan terhadap sistem SPSW. Akan tetapi, untuk panjang bentang antar kolom yang besar penggunaan sistem SPSW dapat menjadi alternatif. Indonesia is located in earthquake risk area, thus the construction of seismic resisting structures is important. In general, reinforcement concrete is used for the structural of buildings, while the use of steel material, special moment frames (SMF) is more commonly used as a seismic force-resistant frame system. According to the standard provision of ASCE/SEI 7-10, the seismic resisting systems for steel buildings are special plate shear walls (SPSW), special truss moment frames (STMF) and other specialized systems. This paper will present analytical models of SMF and SPSW, which is studied further to determine the potential use in Indonesia. To overcome this, parametric study is used to develop design variations with the SMF system cases on different column distance designed to find the most economical structure. The results of comparative design study shown that the SMF system is suitable to be applied for the columns distance with short span and verified to be more economical. However, for long span of columns distance the use of SPSW system can be an alternative.

Authors: Dana Badara Shofi , Adenan Moh. , Zainuri Zainuri
Published: October 2019

Fluktuasi nilai tukar dalam jangka pendek dapat dijelaskan melalui pendekatan struktur mikro pasar valuta asing. Konsep yang dibangun oleh pendekatan struktur mikro pasar valuta asing adalah bahwa berita makroekonomi (berita di koran) dapat memengaruhi nilai tukar di pasar valuta asing dengan mengubah asumsi para pelaku. Tujuan penelitian ini, menganalisis dampak berita makroekonomi domestik dan Cina dalam memengaruhi pergerakan nilai tukar di Indonesia. Variabel yang digunakan adalah nilai tukar dan berita makroekonomi domestik dan Cina pada 2/1/2013-31/12/2018. Proksi sebagai berita makroekonomi adalah pertumbuhan ekonomi (GDP), retail sales dan transaksi berjalan. Alat analisis Generalized Methods of Moments (GMM) digunakan untuk meninjau hubungan berita makroekonomi dengan nilai tukar. Hasil penelitian ini menunjukan bahwa berita makroekonomi domestik dan Cina memiliki pengaruh terhadap pergerakan nilai tukar di Indonesia.

Sınıraşan
niteliğe haiz çevre sorunlarına uluslararası düzeyde çözüm arama uğraşlarının
giderek önem kazanmaya başladığı bir süreçte, Birleşmiş Milletler’in, İklim
Değişikliği Çerçeve Sözleşmesi/BMİDÇS (United Nations Framework Convention on
Climate Change/UNFCCC) ile bu konuda önemli bir adım attığı görülmüştür. BM’nin
1992’de Rio’daki Çevre ve Kalkınma Konferansı’nda imzaya açtığı bu sözleşme,
ülkelerin onaylaması ile 21 Mart 1994’te yürürlüğe girmiştir. BMİDÇS’nin
yürürlüğe girmesinden itibaren ise her yıl “taraflar konferansı (COP)”
düzenlenmeye başlanmış ve 2017 yılının sonuna kadar dünyanın farklı kentlerinde
23 “taraflar konferansı” gerçekleştirilmiştir. Bu çalışmanın amacı, iklim
değişikliği sorununa ilişkin BM dâhilinde ne tür gelişmeler yaşandığını ve ne
kadar yol alınabildiğini belirleyebilmektir. Bunun için özellikle BM Güvenlik
Konseyi’nin (BMGK) iklim değişikliği sorununa yaklaşımına ve BM bünyesinde
gerçekleştirilen konferans, sözleşme, protokol ve anlaşmalara başvurulacaktır.
Bu kapsamda BMİDÇS önemli bir başlangıç kabul edilip incelenecek, ayrıca,
önemlerine binaen iki ayrı taraflar konferansının ürünü olan Kyoto Protokolü’ne
ve Paris Anlaşması’na daha detaylı yaklaşılacaktır.

From Desktop to Benchtop – A Paradigm Shift in Asymmetric Synthesis
Authors: Patrascu Mihai Burai , Pottel Joshua , Pinus Sharon , Bezanson Michelle , Norrby Per-Ola , Moitessier Nicolas
Published: October 2019

The organic chemist’s toolbox is vast with technologies to accelerate the synthesis of novel chemical matter. The field of asymmetric catalysis is one approach to access new areas of chemical space and computational power is today sufficient to assist in this exploration. Unfortunately, existing techniques generally require computational expertise and are therefore under-utilized in synthetic chemistry. We present herein our platform Virtual Chemist that allows bench chemists to predict outcomes of asymmetric chemical reactions ahead of testing in the lab, in just a few clicks. Modular workflows facilitate the simulation of various sets of experiments, including the four realistic scenarios discussed: one-by-one design, library screening, hit optimization, and substrate scope evaluation. Catalyst candidates are screened within hours and the enantioselectivity predictions provide substantial enrichments compared to random testing. The achieved accuracies within ~1 kcal/mol provide new opportunities for computational chemistry in asymmetric catalysis.
