This study proposed to examine the alfalfa varieties suitable for further field experiments in Sa Kaeo province in order to cultivate alfalfa plants for a meat goat diet. Four varieties of alfalfa were collected from four distributors, source from the Republic of Turkey (coded as AC1), source from the United Kingdom (coded as AC2) and source from the United States of America (coded as AC3 and AC4, respectively). Their growth rate, yield and chemical composition were analysed in Sa Kaeo province. The results show that the plant height, the number of leaves per plant and the leaf width increased from 30 to 90 days after all the varieties were planted. There were significant differences between the varieties in their chemical composition after the first (90 days) and second (120 days) harvest times except for dry matter (DM) 90 days after planting. To determine the effects of increasing levels of alfalfa dehydrated pellets (ADP) in total mixed ration (TMR) on feed intake and productive performance of meat goat, a randomized complete block design experiment was conducted with 9 crossbred Native-Anglo Nubian goats, 3-4 months’ old, with body weight ranging from 8-10 kg which were fed received 0%, 10% and 20% of ADP in a TMR. The results revealed that increasing levels of ADP with 10% and 20% in the diet had no effect on DM intake, average daily gain, nutrient digestibility and blood urea nitrogen.

In this study, we make QSAR models from 29 of BA derivatives’ HIV maturation inhibition activities against their 3D descriptors. The best model involve 5 descriptors as follows: 1/log EC50 = -462.275 + (69.213 × TDB6u) + (723.745 × TDB6e) + (-0.576 × FPSA-3) + (0.849 × RDF140u) + (0.302 × RDF80e) r2 training = 0.7918; Q2 test = 0.9644; r2test = 0.9798; and r2m-test = 0.9445 TDB6u and TDB6e are the 3d topological distance-based autocorrelation-lag 6 /unweighted and weighted by Sanderson electronegati-vities, respectively. FPSA-3 is the value of charge weighted partial positive surface area / total molecular surface area. RDF140u is radial distribution function-140 / unweighted. RDF80e is radial distribution function-080/weighted by relative Sanderson electronegativities. The QSAR model was then used to design and predict some of the new BA derivatives’ HIV maturation activities. The best predicted compound had pEC50 value of -0.838 and EC50 value of 0.064 nM with the chemical IUPAC name of 4‐[(1R, 3aR, 5aR, 5bR, 7aS, 11aR, 11bS, 13aS,13bS)‐5a, 5b, 8, 8, 11b pentamethyl‐1‐(prop‐1‐en‐2‐yl)‐3a[({2‐[4‐(pyrimidin2yl)piperazin-1-yl]ethyl}amino) methyl]‐icosahydro‐1H-cyclopenta[a]chrysen‐9‐yl]benzoic acid. We also suggest the synthetic route to the proposed compound.

Phytoremediation is one effective method used for reducing the iron (Fe) from waters. Azolla pinnata is a plant that has potential as an agent of phytoremediation of Fe in waters. This study aims to verify the ability of Azolla pinnata to reduce Fe from sand excavated water in Pasir Sakti District, East Lampung Regency, Indonesia. The study was conducted with three treatments. The treatments of 25% cover area, 50% cover area, and 75% cover of Azolla pinnata, with three replications each. The experiments were carried out until the water quality became suitable for aquaculture. The results showed that the area cover of Azolla pinnata had a different effect (P <0.05) on the decrease in iron concentration in the water. The treatment with 75% cover area of Azolla pinnata, showed a reduction percentage of iron concentration of 98.10%. It is the most significant reduction percentage of iron. Whereas the treatment with 25% and 50% Azolla pinnata cover area of succeeded in reducing the concentration of Fe in water 92.5% and 93.3% respectively.
Phase-preserving NALM regenerator with lower input power by optimizing
the nonreciprocal phase shifter
Authors: Zhang Shouqi , Wu Baojian , Wen Feng
Published: December 2020

We propose a new nonlinear amplifying loop mirror (NALM)-based
phase-preserving amplitude regenerator (so-called NP-NALM) by
introducing a nonreciprocal phase shifter to further improve the
regeneration performance. The theoretical model of the NP-NALM
structure and the amplitude regeneration and phase-preserving
conditions are presented. It is shown that the optimal working point
power reduces with the increase of the nonreciprocal phase shift in
the available range and the first working point power can be as low as
115 mW by optimizing the nonreciprocal phase shifter. We also
investigate the cascaded NP-NALM transmission system for quadrature
phase-shift keying signals with amplified spontaneous emission noise
and the output error vector magnitude (EVM) can reduce to 23% from the
EVM limit of 30%, corresponding to bit error ratio of

An improved approach for fault detection by simultaneous overcoming of high-dimensionality, autocorrelation, and time-variability
Authors: Hajarian Nastaran , Movahedi Sobhani Farzad , Sadjadi Seyed Jafar
Published: December 2020

The control charts with the Principal Component Analysis (PCA) approach and its extension are among the data-driven methods for process monitoring and the detection of faults. Industrial processing data involves complexities such as high dimensionality, auto-correlation, and non-stationary which may occur simultaneously. An efficient fault detection technique is an approach that is robust against data training, sensitive to all the feasible faults of the process, and agile to the detection of the faults. To date, approaches such as the recursive PCA (RPCA) model and the moving-window PCA (MWPCA) model have been proposed when data is high-dimensional and non-stationary or dynamic PCA (DPCA) model and its extension have been suggested for autocorrelation data. But, using the techniques listed without considering all aspects of the process data increases fault detection indicators such as false alarm rate (FAR), delay time detection (DTD), and confuses the operator or causes adverse consequences. A new PCA monitoring method is proposed in this study, which can simultaneously reduce the impact of high-dimensionality, non-stationary, and autocorrelation properties. This technique utilizes DPCA property to decrease the effect of autocorrelation and adaptive behavior of MWPCA to control non-stationary characteristics. The proposed approach has been tested on the Tennessee Eastman Process (TEP). The findings suggest that the proposed approach is capable of detecting various forms of faults and comparing attempts to improve the detection of fault indicators with other approaches. The empirical application of the proposed approach has been implemented on a turbine exit temperature (TET). The results demonstrate that the proposed approach has detected a real fault successfully.
Talking about suicide: An uncontrolled trial of the effects of an Aboriginal and Torres Strait Islander mental health first aid program on knowledge, attitudes and intended and actual assisting actions

Published: December 2020

Objective

Suicide is a leading cause of death among Aboriginal and Torres Strait Islander people. Friends, family and frontline workers (for example, teachers, youth workers) are often best positioned to provide initial assistance if someone is at risk of suicide. We developed culturally appropriate expert consensus guidelines on how to provide mental health first aid to Australian Aboriginal and Torres Strait Islander people experiencing suicidal thoughts or behaviour and used this as the basis for a 5-hour suicide gatekeeper training course called Talking About Suicide. This paper describes the outcomes for participants in an uncontrolled trial of this training course.

Methods

We undertook an uncontrolled trial of the Talking About Suicide course, delivered by Aboriginal and Torres Strait Islander Mental Health First Aid instructors to 192 adult (i.e. 18 years of age or older) Aboriginal and Torres Strait Islander (n = 110) and non-Indigenous (n = 82) participants. Questionnaires capturing self-report outcomes were self-administered immediately before (n = 192) and after attending the training course (n = 188), and at four-months follow-up (n = 98). Outcome measures were beliefs about suicide, stigmatising attitudes, confidence in ability to assist, and intended and actual actions to assist a suicidal person.

Results

Despite a high level of suicide literacy among participants at pre-course measurement, improvements at post-course were observed in beliefs about suicide, stigmatising attitudes, confidence in ability to assist and intended assisting actions. While attrition at follow-up decreased statistical power, some improvements in beliefs about suicide, stigmatising attitudes and intended assisting actions remained statistically significant at follow-up. Importantly, actual assisting actions taken showed dramatic improvements between pre-course and follow-up. Participants reported feeling more confident to assist a suicidal person after the course and this was maintained at follow-up. The course was judged to be culturally appropriate by those participants who identified as Aboriginal and/or Torres Strait Islanders.

Implications

The results of this uncontrolled trial were encouraging, suggesting that the Talking About Suicide course was able to improve participants’ knowledge, attitudes, and intended assisting actions as well as actual actions taken.

Published: December 2020

Background

A worldwide outbreak of coronavirus disease (COVID-19), since 2019, has brought a disaster to people all over the world. Many researchers carried out clinical epidemiological studies on patients with COVID-19 previously, but risk factors for patients with different levels of severity are still unclear.

Methods

562 patients with laboratory-confirmed COVID-19 from 12 hospitals in China were included in this retrospective study. Related clinical information, therapies, and imaging data were extracted from electronic medical records and compared between patients with severe and non-severe status. We explored the risk factors associated with different severity of COVID-19 patients by logistic regression methods.

Results

Based on the guideline we cited, 509 patients were classified as non-severe and 53 were severe. The age range of whom was 5–87 years, with a median age of 47 (IQR 35.0–57.0). And the elderly patients (older than 60 years old) in non-severe group were more likely to suffer from fever and asthma, accompanied by higher level of D-dimer, red blood cell distribution width and low-density lipoprotein. Furthermore, we found that the liver and kidney function of male patients was worse than that of female patients in both severe and non-severe groups with different age levels, while the severe females had faster ESR and lower inflammatory markers. Of major laboratory markers in non-severe cases, baseline albumin and the lymphocyte percentage were higher, while the white blood cell and the neutrophil count were lower. In addition, severe patients were more likely to be accompanied by an increase in cystatin C, mean hemoglobin level and a decrease in oxygen saturation. Besides that, advanced age and indicators such as count of white blood cell, glucose were proved to be the most common risk factors preventing COVID-19 patients from aggravating.

Conclusion

The potential risk factors found in our study have shown great significance to prevent COVID-19 patients from aggravating and turning to critical cases during treatment. Meanwhile, focusing on gender and age factors in groups with different severity of COVID-19, and paying more attention to specific clinical symptoms and characteristics, could improve efficacy of personalized intervention to treat COVID-19 effectively.
Indole-3-acetic acid synthesized through the indole-3-pyruvate pathway promotes Candida tropicalis biofilm formation

Published: December 2020

We previously found that the elevated abundance of the fungus Candida tropicalis is positively correlated with the bacteria Escherichia coli and Serratia marcescens in Crohn’s disease patients and the three pathogens, when co-cultured, form a robust mixed-species biofilm. The finding suggests that these three pathogens communicate and promote biofilm formation, possibly through secretion of small signaling molecules. To identify candidate signaling molecules, we carried out a metabolomic analysis of the single-species and triple-species cultures of the three pathogens. This analysis identified 15 metabolites that were highly increased in the triple-species culture. One highly induced metabolite was indole-3-acetic acid (IAA), which has been shown to induce filamentation of certain fungi. We thus tested the effect of IAA on biofilm formation of C. tropicalis and demonstrated that IAA promotes biofilm formation of C. tropicalis. Then, we carried out isotope tracing experiments using 13C-labeled-tryptophan as a precursor to uncover the biosynthesis pathway of IAA in C. tropicalis. The results indicated that C. tropicalis synthesizes IAA through the indole-3-pyruvate pathway. Further studies using inhibitors of the indole-3-pyruvate pathway are warranted to decipher the mechanisms by which IAA influences biofilm formation.

Published: December 2020

Se propone la realización de un análisis de composición socio-económica y energética de los hogares argentinos, con el objetivo de generar información que sirva para la definición de políticas de desarrollo en energía solar con una óptica de inclusión y desarrollo social. Para ello, se aplicaron métodos de clustering y análisis de grandes datos, en particular k-means, two step cluster, y análisis de factores principales, a una base de datos construida a partir de datos del Instituto Nacional de Estadísticas y Censos, Secretaría de Energía de la Nación, Ente Regulador Nacional del Gas, Solar and Wind Energy Resource Assessment y National Renewable Energy Laboratory. Como resultado, se evidencian hogares con problemáticas similares con respecto al acceso a los energéticos y otros derechos básicos, el impacto del costo de la energía y el recurso solar disponible. Estas agrupaciones han sido mapeadas al nivel de radio censal, la unidad geográfica y de análisis más pequeña del censo argentino. Así, se concluye con la definición de perspectivas de acción para el desarrollo energético y socialmente inclusivo de cada una de las agrupaciones de hogares, tanto rurales como urbanos.

Published: December 2020

En el marco del análisis espacio-temporal de la Enfermedades Raras (ER) en España, los efectos derivados del Problema de la Unidad Espacial Modificable (PUEM) condicionan la interpretación de los resultados. Este estudio tiene como objetivo comparar indicadores de mortalidad y visualización cartográfica para recomendar la unidad geográfica de trabajo óptima según población, área cubierta y el número de casos de la enfermedad. Se estudiaron los fallecimientos debidos a una ER (Huntington) en tres niveles de agregación espacial; el municipio, la comarca y la provincia. Se diseñó una ratio de adyacencia para observar el efecto de las relaciones de vecindad entre las tres unidades administrativas tratadas. Se calcularon indicadores epidemiológicos de mortalidad, así como indicadores locales de asociación espacial en cada nivel de agregación. Los resultados se representaron cartográficamente utilizando intervalos definidos por el usuario para comparar de forma visual las diferencias estadísticas y cartográficas. El PUEM fue particularmente visible trabajando con datos agregados de ER. Las comarcas representaron el mayor nivel de estabilidad en la ratio de adyacencia así como la unidad geográfica óptima en términos de resolución espacial y variabilidad de la información representada cartográficamente. Este proceso de ayuda en la elección de la escala de trabajo puede ser extrapolado a otras enfermedades o niveles de agregación, como paso previo a análisis epidemiológicos más avanzados.

TERRITÓRIO E PODER: SISTEMA, CONSTRUCTO E ALIENAÇÃO TERRITORIAL
Authors: Bortolin Bianca Caroline , Souza José Gilberto de
Published: December 2020

O artigo realiza uma análise sobre o nível de constructo e alienação territorial presente nos espaços agrários, a partir das práticas socioespacais e as relações de poder em seu conteúdo de classe. Investiga-se uma representação dessas relações, que não esteja circunscrita ao fechado sistema territorial. Elabora-se uma escavação teórico-conceitual e analítica das práticas socioespaciais dos sujeitos as quais compreendemos como resultantes em determinações territoriais que afirmam e/ou infirmam um processo de construção territorial.  Compreende-se que em cada território há relações de poder que são próprias dos sujeitos e ocorrem, em simultaneidade, às relações de poder entre outros territórios e projetos societais. Essas práticas baseiam-se nas necessidades, nos projetos e nas intencionalidades dos grupos sociais que os habitam conduzindo a processos de identidade e/ou alienação territorial.

CARTOGRAFIA E DIREITOS HUMANOS NA ESCOLA PÚBLICA – NOVAS PRÁTICAS NO ESTÁGIO SUPERVISIONADO EM GEOGRAFIA NA UEG - UnU ITAPURANGA(GO)
Authors: Marques Ana Carolina de Oliveira
Published: December 2020

Partimos do pressuposto de Miguel Arroyo: a escola pública tem o dever ético-político-pedagógico de oferecer aos “trabalhadores que estudam” as condições de se entenderem vítimas das injustiças sociais que lhes roubam a humanidade, forjando-lhes sujeitos sem direito a ter direitos. Este é um dos princípios balizadores da formação de professores em Geografia na Universidade Estadual de Goiás, Unidade Itapuranga (Goiás). A oficina “Cartografia e Direitos Humanos” realizada em uma das escolas-campo – a Escola Estadual Zico Coelho – sintetiza o esforço em formar professores com princípios político-pedagógicos sensíveis aos “itinerários humanos” dos educandos; às múltiplas violências das quais são vítimas; aos seus cotidianos enquanto trabalhadores/as – inclusive na infância; aos saberes adquiridos nas experiências radicais de vida. A oficina fora conduzida por estagiários do 6º período de licenciatura. Apresentamos, neste texto, todo o percurso dos estagiários desde a preparação teórico-conceitual, a definição da metodologia e os resultados da intervenção pedagógica. Esperamos que as reflexões compartilhadas agreguem às pedagogias afirmativas do vínculo radical entre educação geográfica, formação de professores e justiça social.
Cómo elaborar un protocolo de prevención de la mutilación genital femenina
Authors: Carrasco Carpio Concepción , Ibañez Carrasco Marta
Published: December 2020

La mutilación genital femenina es una práctica prevalente en 29 países de África. Los movimientos migratorios convierten esta práctica en un tema de interés en España. Esta problemática se aborda desde una perspectiva de diálogo intercultural más que de choque cultural, sin perder de vista que es contraria a los derechos humanos y está catalogada como violencia de género.

La investigación que se presenta, a través de grupos de discusión con agentes clave (educación, sanidad, servicios sociales, centros especializados, organizaciones sin ánimo de lucro y mediadores) ha permitido proponer algunos elementos imprescindibles para que la elaboración de protocolos de prevención de la MGF sea realista, al mismo tiempo que se ha presentado una muestra de los algoritmos resultantes del estudio realizado, en este caso en la región de Castilla-La Mancha.

Published: December 2020

Background: Smoking habits enhance free radical in the body, which oxidize lipids to form malondialdehyde. One group that is vulnerable to smoking is adolescents. Red dragon fruit and red guava have the possibility as functional foods due to their vitamin and phytochemical content, which have antioxidant effects. This is an opportunity to prevent oxidative stress among adolescent smokers.Objectives: This study aimed to analyze the effect of red dragon fruit, red guava, and its combination to total antioxidant capacity (TAC) and malondialdehyde (MDA) levels among adolescent mild smokers.Methods: This research was an experimental study with a randomized pre-test and post-test control group design. Forty-eight subjects of male adolescent aged 16-17 years with mild smoking habits were divided into four groups: the control group (K), the intervention group with 200 grams of red dragon fruit (P1), 200 grams of red guava (P2), and the combination of both (100 grams red dragon fruit + 100 grams red guava) (P3), for 14 days. TAC examination used the DPPH method and MDA levels using the TBARS method were measured before and after the intervention.Results: After 14 days of intervention, the mean TAC was changed by -0,10±0,76 in the K group, 0,97±1,62 in the P1 group, 0,74±1,39 in the P2 group, and 0,74±1,29 in the P3 group. But the changes of TAC in all intervention groups were not significantly different from the control group (p>0,05). The mean MDA level changed by 0,229±0,371 in the K group, decreased by -0,654±0,922 in the P1 group, -0,592±0,818 in the P2 group, and -1,166±0,670 in the P3 group. The mean difference of the MDA level in all intervention groups was significantly different from the control group (p<0,05).Conclusion: Consumption of red dragon fruit, red guava, or a combination of red dragon fruit and red guava can reduce malondialdehyde levels significantly among male adolescent mild smokers. Whereas the total antioxidant capacity was changed but not significant.

Background: Discoloration was one indicator of food damage including in fruits, since the change may be used as a quality measurement. Salak became one of the commodities that often experience the browning reaction that may change the color. Since the yellow was close to the consumer preference along the preservation in salak, this color should be notified and may be represented as polyphenol change. Objectives: The focus of this study was to determine the pattern of inhibition of browning reactions in salak using HIO.Methods: This research determined the color level of yellow using digital color meter of salak that was stored in room temperature in aseptic treatment for 12 days. Result: Discoloration appeared in salak and it was clearly determined the change since a week of storage. The rate of discoloration was able to be detected highly after one week of storage. Conclusion: The discoloration of yellow color and the rate of salak could be detected specifically based on the day of storage. This research may open the information for the consumer to predict the storage time of salak based on the appearance of yellow color.

Published: December 2020

Twenty pasundan cows were divided into two treatments int his study aims to determine the correlation between hematological and blood metabolite on the conception rate of Pasundan cows with synchronized estrus and ovulation. Twenty pasundan cows were divided into two treatments 1) estrus synchronization through double injection 5 ml PGF2α , 2)combination of 5 ml PGF2α per cow and 2.5 ml GnRH per cow intramuscularly. The heat of cow is immediately inseminated 2 times with an interval of 6 hours. The observed variables were estrus percentage, conception rate, erythrocyte, leucocyte, hemoglobin, β-hydroxy butyric acid (BHBA), blood urea nitrogen (BUN), and non esterificated acid (NEFA). Data were processed by analysis of variance and correlation- regression. The result showed that PGF2α with GnRH injection resulted in a better conception rate than that of PGF2α (70% vs 60%), the average plasma concentration of erythrocyte, leucocyte, hemoglobin, NEFA, BUN, and BHBA levels respectively was 6.61±0.19 million/µl, 11.30±0.35 thousand/µl, 10.63±0.35 g/dL, 1.65±018 mmol/L, 10.28±1.50 mg/dL, 21.46±1.96 mg/dL. The data obtained were performed variance analysis and correlation regression analysis using SPSS 16.0. The results of the regression analysis showed that the concentration of erythrocytes, leucocytes, hemoglobin, NEFA, BUN, and BHBA had a significant relationship (P<0.05) with pregnancy, and coefficient of determination were 86.4%, 69.1%, 98.3%, -11.7%, -8.2%, -7.0%, respectively. It was concluded that the pregnancy of Pasundan cows has a strong relation between the conception rates with hematological, however blood metabolites showed a weak relation and inversely proportional.

Published: December 2020

Adolescences' excessive online self-disclosure is now a social phenomenon arising in social media use. The adolescences also tend to share their privacy. This study aims to determine whether extraversion personality, perceived privacy risks, the convenience of maintaining relationships, and online self-presentation influence self-disclosure in adolescents. This study involved 619 adolescents (185 male and 434 female) aged 13-22 years (M = 19.39, SD = 1.83). The participants are active social media users collected from several areas in Indonesia. Multiple regression analysis is used to test the hypothesis. The results show that several variables simultaneously affect online self-disclosure in adolescents (R2 = .422; F (4, 614) = 111.944, p < .01). However, in details, online self-presentation does not have a significant effect on online self-disclosure among adolescents. This result shows that personality factors and adolescent perceptions of the low privacy risk on social media, as well as the goal of maintaining social relations with other members of social media, encourage them to be more online disclose on social media.

There were 23% of children with underweight, 78.7% children get high risk of psychosocial stimulation, and 57.6% have a good cognitive development. The correlation test showed that there were significant association between the psychosocial stimulation and nutritional status to the cognitive development. Regression model also showed that cognitive development was predicted by maternal status (working mothers/housewife), nutritional status, and psychosocial stimulation.
How environmental certification can affect the value of organizations? The case of Forest Stewardship Council certification
Authors: Sansalvador M.E. , Brotons J.M.
Published: December 2020

Forest certification appeared in the 1990's as a way to deal with forest deterioration. Currently, however, public opposition can limit its effectiveness. Business policy makers should analyze how Forest Stewardship Council (FSC) certification can affect the value of companies. Yet,
the relation between financial performance and forest certification systems is a subject which has not been explored to a great extent, and the measures used for evaluating financial performance in published studies are not based on business valuation. In this study, Spanish companies with
FSC certification are valuated under the premises of implementation and non-implementation of FSC certification. Given the uncertainty inherent in the second option, the use of fuzzy mathematics has been considered a suitable tool. According to the results obtained, it can be concluded that
regardless of size or business sector, FSC certification is effective in increasing the value of companies. The pap er offers economic arguments for managers to become more environmentally responsible.

Authors: Gerth Jordan J. , Garcia Raymond K. , Hoese David J. , Lindstrom Scott S. , Schmit Timothy J.
Published: December 2020

The Satellite Information Familiarization Tool (SIFT) is an open-source, multi-platform graphical user interface designed to easily display spectral and temporal sequences of geostationary satellite imagery. The Advanced Baseline Imager (ABI) and Advanced Himawari Imager (AHI) on the “new generation” of geostationary satellites collect imagery with a spatial resolution four times greater than previously available. Combined with the increased number of spectral bands and more frequent imaging, the new series imagers collect approximately 60 times more data. Given the resulting large file sizes, the development of SIFT is a multiyear effort to make those satellite imagery data files accessible to the broad community of students, scientists, and operational meteorologists. To achieve the objective of releasing software that provides an intuitive user experience to complement optimum performance on consumer-grade computers, SIFT was built to leverage modern graphics processing units (GPUs) through existing open-source Python packages, and runs on the three major operating systems: Windows, Mac, and Linux. The United States National Weather Service funded the development of SIFT to help enhance the satellite meteorology acumen of their operational meteorologists. SIFT has basic image visualization capabilities and enables the fluid animation and interrogation of satellite images, creation of Red-Green-Blue (RGB) composites and algebraic combinations of multiple spectral bands, and comparison of imagery with numerical weather prediction output. Open for community development, SIFT users and features continue to grow. SIFT is freely available with short tutorials and a user guide online. The mandate for the software, its development, realized applications, and envisioned role in science and training are explained.

Poduzetnici imaju ključnu ulogu u izgradnji održivog i konkurentnog društva. Iako velikim dijelom njihov uspjeh ovisi o njima samima i njihovim kompetencijama, značajnu ulogu u njihovu djelovanju ima i okruženje u kojem se nalaze. Što je poduzetnički ekosustav razvijeniji i poticajniji, veće su mogućnosti da će svojim idejama imati pozitivan utjecaj na kvalitetu života i u svojoj zajednici. Ovaj rad odgovara na dva glavna istraživačka pitanja: a) Posjeduju li poduzetnici iste poduzetničke osobine? i b) Ovisi li poduzetnička efikasnost o razvijenosti okruženja (regije) u kojoj poduzetnici djeluju? Rad se temelji na usporedbi poduzetničkih osobina i poduzetničkog okruženja u Osječko-baranjskoj i Dubrovačko-neretvanskoj županiji. U empirijskom dijelu analizirani su podaci dobiveni primarnim istraživanjem na uzorku od 25 poduzetnika iz Osječko-baranjske te 25 poduzetnika iz Dubrovačko-neretvanske županije koji posluju u djelatnostima vezanim uz turizam. Na temelju provedene analize, doneseni su zaključci o utjecaju poduzetničkih osobina i poslovnog okruženja na učinkovito poslovanje poduzetnika. Rezultati ovoga istraživanja mogu poslužiti kao temelj za provođenje opsežnijeg istraživanja prikupljanjem većega reprezentativnog uzorka, ali i za nova istraživanja koja tematiziraju utjecaj stupnja regionalne razvijenosti na rast i razvoj poduzetničkih pothvata.
Značaj arheoloških lokaliteta na području Ražanca, Podvršja i Ljupča u funkciji valorizacije kulturnog i sportskog turizma
Authors: Miočić Josip , Vukašina Martina
Published: December 2020

U radu se donosi pregled najznačajnijih arheoloških lokaliteta na širem području mjesta Ražanca, Podvršja i Ljupča, koji datiraju u vrijeme od prapovijesti pa sve do novog vijeka. Budući da se značajan dio istraženih lokaliteta nalazi na prirodnim uzvisinama, morskim uvalama te vodom bogatim područjima, ističe se njihova uloga kao svojevrsnih katalizatora u promociji kulturnih, ali i prirodnih ljepota toga kraja. U tome kontekstu, lokaliteti postaju važna odredišta u razvoju kulturnog i sportskog turizma, kao ujedinjenog oblika turističke ponude lokalne zajednice. Posebno se ističe položaj Ljubljana iznad Ljupča (Castrum Liube) kao kompleksno arheološko nalazište koje nudi slojevitu povijesnu priču. Spomenuti položaj iznad Ljupča je zbog svojega prirodnog okruženja idealan za postavljanje kulturnih te sportsko-rekreacijskih staza, a u konačnici to područje ima i izvrsne predispozicije za formiranje arheološkog parka. Takvo što bi zasigurno utjecalo na lokalni ekonomski rast i razvoj. Posebice je to izraženo na ekonomskom utjecaju organizacije kulturnih i sportskih manifestacija.
La memoria en la escuela como estrategia pedagógica y de investigación
Authors: Sánchez Bolaños Juan Guillermo
Published: December 2020

Este artículo de investigacion muestra los resultados de una experiencia de aula en la que la escuela se convierte en un escenario para la reconstrucción de la memoria e historia de Colombia, acercando a los estudiantes a los huellas del conflicto armado, no tanto desde la clase magistral y la consulta de textos especializados, sino acudiendo a la memoria viva de los pueblos, presente en los adultos mayores de la sociedad Esto nos ayudó a establecer comunicación y relación entre estos relatos vernáculos de la historia y los que se construyen en la academia, así como también involucró a los diferentes miembros de la comunidad educativa, en torno a temas como la opresión, el desprecio y la violencia. Los resultados de esta experiencia investigativa en la escuela redundan en la participación de los estudiantes a lo largo del proceso de formulacion del proyecto, socialización a padres e institucion educativa, actividades de aprendizaje, foros en clase, realización y transcripción de las entrevistas, hasta la apuesta por la escritura y la apreciación artística. El efecto más importante de esa participación y orientación, fue no sólo el aproximarse a los fenómenos derivados de la guerra, los derechos humanos y el Estado, desde los textos especializados y las versiones oficiales de la historia, sino también desde la memoria de las personas de la comunidad. Conocer la historia y reconocer la memoria de esa historia en los familiares y vecinos de la comunidad, nos condujo por una senda en la que es posible aportar a la construcción de la paz y la educación en Colombia.
COVID-19 Induced Economic Uncertainty: A Comparison between the United Kingdom and the United States
Authors: Pata Ugur Korkut
Published: December 2020

The purpose of this study is to investigate the effects of the COVID-19 pandemic on economic policy uncertainty in the US and the UK. The impact of the increase in COVID-19 cases and deaths in the country and the increase in the number of cases and deaths outside the country may vary. To examine this, the study employs the bootstrap ARDL cointegration approach from March 8, 2020 to May 24, 2020. According to the bootstrap ARDL results, a long-run equilibrium relationship is confirmed for five out of the ten models. The long-term coefficients obtained from the ARDL models suggest that an increase in COVID-19 cases and deaths outside of the UK and the US has a significant effect on economic policy uncertainty. The US is more affected by the increase in the number of COVID-19 cases. The UK, on the other hand, is more negatively affected by the increase in the number of COVID-19 deaths outside the country than the increase in the number of cases. Moreover, another significant finding from the study demonstrates that COVID-19 is a factor of great uncertainty for both countries in the short-term.

The paper presents the analysis of possibilities and limitations of using the thermal imaging to monitor the dynamics of temperature field caused by a short-term cryoablation of skin. It is shown that the method allows to remote and intraoperative control the dynamics of the freezing zone diameter as well as to estimate the current diameter of primary cryonecrosis zone. The diameter of primary cryonecrosis zone for this type of tissues reaches 13 mm, which makes it possible to destroy small morbid growth by low temperatures even with a short-term (30 s) croexposure. The using of this method to monitor the process of natural warming has shown the presence of long quasi-stable stage in dynamics of the freezing zone diameter with a slight change in the temperature field. This fact is likely due to structural changes in frozen tissues.

Published: December 2020

From the very beginning of formation of Mikolaiv as the center of shipbuilding and command of the Black Sea fleet and ports medical aid to builders of the shipyard and the city, workers of admiralty, military men and inhabitants of the city was provided by sea hospital. With the growth of the civilian population, there was a need for a city hospital, which was established in 1838. Gradually expanding to 35, 80, 150 beds, the hospital still did not meet the needs of the city. In 1890, the city authorities built their own premises, further expansion and arrangement of which, formed a powerful hospital with experienced staff. A worthy addition to it was the Jewish hospital, which since 1866 operated in the city in the pre-Soviet period.
