Relevance. Discussion of the criteria for decision making “amputation vs. preservation”, when viability of the extremity is uncertain, has been continuing. The case description. The lower extremity of a serviceman was injured by a caterpillar tractor. The severity of the damage was determined by the following conditions: open segmental fracture of the femoral diaphysis, 5 cm traction-compression damage of the popliteal artery, acute thrombosis of the popliteal and tibial arteries, sciatic nerve damage, circular detachment of the thigh skin, acute hemorrhage, II degree shock, and uncompensated lower extremity ischemia throughout 24 hours. The MESS score of the injured extremity was 8 indicating that an amputation would have been considered. Nevertheless, we choose the organ preservation solution with the revascularization of the injured limb segment. A multi-stage treatment was carried out including stabilization of bone fragments, primary reconstruction of the popliteal artery to restore the arterial blood flow in the injured extremity, reperfusion injury and myoglobinuria elimination, intensive kidney protection therapy, infection management, skin defects replacement, orthopedic surgery. As a result of the treatment, the injured limb was saved. The femur fracture healed allowing the patient to walk without assistance. Conclusion. The use of the programmed surgical treatment for severe mechanical injury of the lower extremity, an individual multi disciplinary approach, assessing the severity of systemic disorders, and timely use of extracorporeal detoxification made it possible to avoid amputation, perform organ preservation surgery, and create favorable conditions for restoring the supporting function of the lower extremity.

A potent anti-inflammatory effect and wide application of corticosteroids were the origin of their extensive use for treatment of diseases and injuries of the shoulder joint. The authors describe a clinical case of tumor-like cyst in the proximal humerus after intra-articular injection of glucocorticosteroid (GCS) in a 43 year old woman. Current medical literature reports various complications following GCS injections but the authors found no other cases of tumor-like cyst in proximal humerus associated with intra-articular GCS injection. This can be an underestimated phenomenon or a unique case. In any case, all physicians performing treatment and diagnostics medication blockades of the large joints should be aware of this occurrence. The authors assume that such complication can be prevented by clear understanding of shoulder joint anatomy and current visualization techniques such as ultrasound navigation.

Minimally Invasive Plate Osteosynthesis for Distal Radius Fractures: Are There Any Advantages Against Conventional Technique?
Authors: Maximov B. I.
Published: March 2020

Purpose of the study — to illustrate the potential and to evaluate the late term results of minimally invasive plate fixation for distal radius fractures (DRF) and compare it to the treatment outcomes for patients with similar injuries where internal fixation was performed through conventional volar surgical approach. Material and Methods. 96 patients with DRF fractures were included into the study who underwent volar plate fixation by with angular stability. The main group included 42 patients (29 women and 13 men) with DMR where minimally invasive volar approach was used. Mean age of patients was 38 years (from 21 to 57 years). Control group consisted of 54 patients (33 women and 21 men) with mean age of 43 years (from 26 to 64 years) who underwent fracture stabilization via conventional volar approach. Minimal follow up after surgery and discharge was 3 months. In the late period roentgenological, functional and cosmetic outcomes were evaluated as well as patients’ satisfaction by QuickDASH-9 survey. Results. 95 patients (98.9%) demonstrated fracture consolidation in terms up to 6 weeks irrespective of surgical technique which was confirmed by X-rays during control examination. In one female patient (1.1%) consolidation following minimally invasive plating was not achieved even in one year after surgery which was considered as distal radius pseudarthrosis but featuring excellent functional outcome. Surgery time for minimally invasive fixation was 47 (41;53) minutes and for conventional surgical approach – 43 (37;46) minutes (р = 0.731). Mean time of image intensifier use during internal fixation averaged 54 (47;63) seconds during minimally invasive technique and 33 (29;37) seconds for conventional open technique (р = 0.046). Statistically significant larger flexion and extension ranges, pronation and supination angles as well as higher grip force were observed in the group of minimally invasive internal fixation in 1, 2 and 3 months after the surgery (р0.001). Statistically lower scores for QuickDASH-9 survey were reported for the main group in 2 and 3 months postoperatively (р0.001). Cosmetic results were better in patients after minimally invasive approach. Conclusion. Minimally invasive plating fixation of DRF is the efficient and relatively safe surgical option for such injuries. The key arguments for such approach: preservation of bone vascularization which minimally slows down fracture healing, reduced risk of infectious complications, fast functional wrist recovery already in early postoperative period as well as satisfaction of patients with cosmetic effects.

Authors: Bloom Patricia , Wang Thomas , Marx Madeline , Tagerman Michelle , Green Bradley , Arvind Ashwini , Ha Jasmine , Bloom Judith , Richter James M
Published: March 2020

Background

Ascites is a common, painful, and serious complication of cirrhosis. Body weight is a reliable proxy for ascites volume; therefore, daily weight monitoring is recommended to optimize ascites management.

Objective

This study aims to evaluate the feasibility of a smartphone app in facilitating outpatient ascites management.

Methods

In this feasibility study, patients with cirrhotic ascites requiring active management were identified in both inpatient and outpatient settings. Patients were provided with a Bluetooth-connected scale, which transmitted weight data to a smartphone app and then via the internet to an electronic medical record (EMR). Weights were monitored every weekday. In the event of a weight change of ≥5 lbs in 1 week, patients were called and administered a short symptom questionnaire, and providers received an email alert. The primary outcomes of this study were the percentage of enrolled days during which weight data were successfully transmitted to an EMR and the percentage of weight alerts that prompted responses by the provider.

Results

In this study, 25 patients were enrolled: 12 (48%) were male, and the mean age was 58 (SD 13; range 35-81) years. A total of 18 (72%) inpatients were enrolled. Weight data were successfully transmitted to an EMR during 71.2% (697/979) of the study enrollment days, with technology issues reported on 16.5% (162/979) of the days. Of a total of 79 weight change alerts fired, 41 (52%) were triggered by weight loss and 38 (48%) were by weight gain. Providers responded in some fashion to 66 (84%) of the weight alerts and intervened in response to 45 (57%) of the alerts, for example, by contacting the patient, scheduling clinic or paracentesis appointments, modifying the diuretic dose, or requesting a laboratory workup. Providers responded equally to weight increase and decrease alerts (P=.87). The staff called patients a mean of 3.7 (SD 3.5) times per patient, and the number of phone calls correlated with technology issues (r=0.60; P=.002). A total of 60% (15/25) of the patients chose to extend their participation beyond 30 days. A total of 17 patient readmissions occurred during the study period, with only 4 (24%) related to ascites.

Conclusions

We demonstrated the feasibility of a smartphone app to facilitate the management of ascites and reported excellent rates of patient and provider engagement. This innovation could enable early therapeutic intervention, thereby decreasing the burden of morbidity and mortality among patients with cirrhosis.

Authors: Wong Man Kin , Cheng Sai Yip Ronald , Chu Tsun Kit , Lam Fung Yee , Lai Shiu Kee , Wong Kai Chung , Liang Jun
Published: March 2020

BACKGROUND

The nonpharmacological approach to diabetic control in patients with diabetes focuses on a healthy diet, physical activity, and self-management. Therefore, to help patients change their habits, it is essential to identify the most effective approach. Many efforts have been devoted to explain changes in or adherence to specific health behaviors. Such efforts have resulted in the development of theories that have been applied in prevention campaigns and include brief advice and counseling services. Within this context, motivational interviewing (MI) has proven to be effective in changing health behaviors for specific cases. However, stronger evidence is needed on the effectiveness of MI in treating chronic pathologies such as diabetes.

OBJECTIVE

This study will obtain preliminary data on the impact of a nurse-led MI intervention in improving glycemic control, as well as clinical, psychosocial, and self-care outcomes for individuals with type 2 diabetes mellitus when compared with usual care, with the aim of improving diabetic control in patients with diabetes.

METHODS

An open, two-arm, parallel, randomized controlled, pilot exploratory trial will be performed. Two government outpatient clinics in the New Territories West Cluster in Hong Kong will be involved. In total, 20 to 25 participants will be invited in each arm. Intervention participants will receive face-to-face MI interventions in addition to their usual care from the clinic. Control participants will only receive usual care. Outcomes are assessed at baseline, 6 months, and 12 months. The primary outcome measure is glycated hemoglobin levels. Secondary outcomes include blood pressure, BMI, hip and waist circumference, fasting blood, and psychosocial and self-care measures.

RESULTS

This study is currently underway with funding support from the Hong Kong College of Family Physician Research Seed Fund 2017.

CONCLUSIONS

MI skills constitute the main strategies primary care nurses use on their patients. Having economical, simple, effective, and applicable techniques is essential for primary care professionals to help their patients change their lifestyle and improve their health. This study will provide scientific evidence on the effectiveness of MI. It will be performed with strict control over the data collection, ensuring the maintenance of therapeutic integrity.

Authors: Wang Guiying , Yang Xiao-Xian , Xiong Ziyu , Corsi Daniel J , Wen Shi Wu , Zhang Li , Xie Rihua
Published: March 2020

BACKGROUND

Sleep quality is often affected by pregnancy, and exercise may improve sleep quality in pregnancy. However, the literature on the effect of integrating smartphones with continuous exercise coaching to improve sleep is sparse.

OBJECTIVE

This study aimed to explore the effect of continuous exercise coaching through smartphone on sleep quality for pregnant women.

METHODS

Pregnant women who met the eligibility criteria and agreed to participate at their first prenatal visit were enrolled and divided into two groups: group A (with continuous exercise coaching through smartphone) and group B (without exercise coaching). Pittsburgh Sleep Quality Index (PSQI) scale was used to measure the sleep quality. Chi-square test was used for categorical variables and t-test was used for continuously distributed variables for the comparison between the two groups.

RESULTS

In the 2nd trimester, means (SDs) of global score (9.46 (SD 3.46)), subjective sleep quality score (1.64 (SD 0.72)), and daytime dysfunction score (0.98 (SD 0.82) in group A (50 women)) were lower than in group B (50 women): 11.34 (SD 3.93), 2.02 (SD 0.74), and 1.48 (SD 0.84), respectively. In the 3rd trimester, means (SDs) of global score (10.16 (SD 3.00)), sleep efficiency score (1.64 (SD 0.72)), and daytime dysfunction score (1.86 (SD 0.67)) in group A were lower than in group B: 12.10 (SD 3.51), 1.82 (SD 0.80), and 1.78 (SD 0.76), respectively. In group A, global score of PSQI decreased from the 1st to 2nd trimester and from the 2nd to 3rd trimester. No inter-trimester change in global score of PSQI was observed in group B.

CONCLUSIONS

Our preliminary analysis suggests that continuous exercise coaching through smartphone by health professionals may be an effective way to improve sleep quality in pregnancy.
NARASI HEROISME PEREMPUAN DALAM ISU LINGKUNGAN (Analisis Framing Berita Farwiza Farhan di Media Daring Lokal dan Nasional)
Authors: Fitri Ainal , Maulina Putri
Published: March 2020

Environmental discourse is considered as one of the essential narratives since it involves the role of women. In the gender perspective, women in environmental issues are often described as a sidekick. Farwiza Farhan is one of the environmentalists who contributes to the environmental campaign effort. The study aims to focus on the framing of Farwiza Farhan’s figure against her contribution as the keeper of the Leuser Ecosystem (KEL) on online media environmental reports. This study used the Framing Analysis approach, Environmental Journalism, and Heroism concept. The researchers chose and analyzed three news from online news media: serambinews. com as a local source; and republika. co. id and bbc. com as national sources. This research was analyzed by using Zhongdang Pan and Gerald M. Kosicki’s Framing Analysis method. The finding shows that the news media frames Farwiza Farhan as an environmental activist with a heroism narrative. Farwiza is portrayed as a heroic, selfless, courageous, and intelligent personality. She is adaptive and determined to deal with conflict, and she also has initiative and leadership. Heroism is perceived as an environmental perspective-journalism strategy of online news media to deliver environmental knowledge and to raise public awareness towards the environmental issue.

The impact of five long-term contrasting tillage systems on maize productivity parameters
Authors: Romaneckas Kestutis , Avizienyte Dovile , Adamaviciene Aida , Buragiene Sidona , Kriauciuniene Zita , Sarauskis Egidijus
Published: March 2020

Maize productivity is mainly constrained by the climate, meteorological and soil conditions, and agro-technological practice. Reduced primary tillage intensity might be a method to optimize the complex interactions between these conditions. An 8-year field experiment was designed to test this. The aim of the experiment was to establish the influence of deep and shallow ploughing, chiselling, disking and no-tillage systems on parameters of maize productivity. No-tillage resulted in a significant decrease in maize stand density compared with deep and shallow ploughing, as well as chiselling, while maize canopy height and dry biomass was slightly higher in the no-tillage system. Nevertheless, in no-tillage plots the maize yield was insignificantly lower than in deeply and shallowly ploughed plots (on average 3.5–6.4% less). Overall, long-term reduction of primary tillage had less impact on maize productivity parameters than meteorological conditions during the vegetation period.

Published: March 2020

The study aimed at determining the antioxidant effect of natural extracts on the oxidative quality and color variation of rainbow trout fillets during storage at 4 °C. The fillets were marinated and samples from the belly flap area and Norwegian quality cuts were used for lipid oxidation determination while the dorsal region was used for color measurements. The fillets were marinated with the different treatments: 470 mg l-1 of oregano extract, 6.84 ml l-1 of quillaia extract, 7.2 ml l-1 of rosemary extract and 2 ml l-1 of a synthetic antioxidant. Maximum TBARS (Thiobarbituric acid reactive substances) values of belly flap and Norwegian quality cuts occurred at five and six days of storage, respectively. The susceptibility of treatments to lipid oxidation in decreasing order was: control>quillaia>oregano>rosemary>synthetic antioxidant. An increase in lightness (L*) and redness (a*) were observed for rosemary and quillaia extracts when compared to control samples. Marinates with natural antioxidants may be an alternative for extending shelf-life of trout fillets at least during the first six days of storage at 4 °C.
A model for fast delamination analysis of laminated composite structures
Authors: Katajisto Harri , Kere Petri , Lyly Mikko
Published: March 2020

Delamination is one of the major failure mechanisms for composites and traditionally the simulation requires high expertise in fracture mechanics and dedicated knowledge of the Finite Element Analysis (FEA) tool. Yet, the simulation cycle times are high. Geometrically nonlinear analysis approach, which is based on the Reissner-Mindlin-Von K´arm´an type shell facet model, has been implemented into the Elmer FE solver. Altair ESAComp software runs the Elmer Solver in the background. A post-processing capability, which enables the prediction of the delamination onset from the FEA output, has been implemented into the AltairESAComp software. A Virtual Crack Closure Technique (VCCT) speciﬁcally developed for shell elements deﬁning the Strain Energy Release Rate (SERR) related to the diﬀerent delamination modes at the crack front is used. The onset of delamination is predicted using the relevant delamination criteria that utilize the SERR data and material allowables in the form of fracture toughness. The modeling methodology is presented for laminates including initial through-the-width delamination. Examples include delamination in the solid laminate and debonding of the skin laminate in the sandwich structure. Rather coarse FE mesh has proved to yield good results when compared to typical approaches that utilize the standard VCCT or Cohesive Zone Elements.

Published: March 2020

Ингибирующий лейкемию фактор (LIF) обладает неоднозначными физиологическими эффектами при эссенциальной артериальной гипертензии (ЭАГ). Опровергается постулат об идентичности STAT3-сигнализации в клетках миокарда и эндотелиальных/гладкомышечных клетках, что значимо при длительном воздействии цитокинов-лигандов gp 130 (в частности LIF). При этом отсутствуют данные о суточных характеристиках содержания LIF в крови с потенциальными вторичными изменениями его патофизиологических эффектов. Целью исследования было проанализировать особенности суточных ритмов содержания LIF в сыворотке периферической крови больных ЭАГ II стадии, определенного в пяти временных точках в зависимости от применения гипотензивной терапии и частоты развития осложнений в последующие 5 лет наблюдения. У 60 больных ЭАГ II стадии иммуноферментным методом определяли уровни LIF в сыворотке периферической крови в 8.00, 14.00, 20.00, 2.00, 8.00 ч до и после года гипотензивной терапии. Выявленные закономерности суточного ритма содержания LIF в сыворотке крови больных ЭАГ II стадии в виде увеличения в 20.00 ч на 15% (p < 0,001) и выше с максимальным ростом в 2.00 ч на 22% (p < 0,001) и более при сравнении с индивидуальным уровнем в 8.00 ч можно характеризовать как патологические, а их сохранение после года гипотензивной терапии служит признаком прогредиентного течения гипертензии с повышением риска развития сердечно-сосудистых осложнений (инфаркт миокарда, острое нарушение мозгового кровообращения) в 6 раз.

OBJECTIVE

To evaluate agreement in results obtained with an MRI-based grading scheme and a macroscopic observation-based grading scheme when used to assess intervertebral disk (IVD) degeneration in cats.

SAMPLE

241 MRI and 143 macroscopic images of singular IVDs in 44 client-owned cats (40 cadaveric and 4 live).

PROCEDURES

Singular images of IVDs were obtained of live cats admitted for treatment of suspected neurologic disease (MRI images of IVDs) and of cadavers of cats euthanized for reasons unrelated to spinal disease (MRI and macroscopic images of IVDs) at the Small Animal Hospital, Vetsuisse Faculty, Zurich, Switzerland, between January 12, 2015, and October 19, 2015. The IVD images were randomized and evaluated twice by 4 observers for each grading scheme. Inter- and intraobserver reliability for the grading schemes was assessed with Cohen weighted κ analysis. Agreement and correlation between results obtained with the 2 grading schemes were determined with Cohen weighted κ and Spearman correlation coefficient (ρ) analyses, respectively.

RESULTS

Inter- and intraobserver agreement between results was substantial to almost perfect (mean weighted κ, 0.66 to 0.83 and 0.71 to 0.86, respectively) for the MRI-based grading scheme and moderate to substantial (mean weighted κ, 0.42 to 0.80 and 0.65 to 0.79, respectively) for the macroscopic observation-based grading scheme. Between the 2 grading schemes, agreement in results was moderate (mean ± SE weighted κ, 0.56 ± 0.05), and the correlation was strong (ρ = 0.73).

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated that the MRI-based and macroscopic observation-based grading schemes used in the present study could be used reliably for classifying IVD degeneration in cats.

Authors: Simcock Ian C. , Hutchinson J. Ciaran , Shelmerdine Susan C. , Matos Jose Novos , Sebire Neil J. , Fuentes Virginia Luis , Arthurs Owen J.
Published: March 2020

OBJECTIVE

To determine optimal sample preparation conditions with potassium triiodide (I2KI) and optimal imaging settings for microfocus CT (micro-CT) of excised cat hearts.

SAMPLE

7 excised hearts (weight range, 10 to 17.6 g) obtained from healthy adult cats after euthanasia by IV injection of pentobarbital sodium.

PROCEDURES

Following excision, the hearts were preserved in 10% formaldehyde solution. Six hearts were immersed in 1.25% I2KI solution (n = 3) or 2.5% I2KI solution (3) for a 12-day period. Micro-CT images were acquired at time 0 (prior to iodination) then approximately every 24 and 48 hours thereafter to determine optimal sample preparation conditions (ie, immersion time and concentration of I2KI solution). Identified optimal conditions were then used to prepare the seventh heart for imaging; changes in voltage, current, exposure time, and gain on image quality were evaluated to determine optimal settings (ie, maximal signal-to-noise and contrast-to-noise ratios). Images were obtained at a voxel resolution of 30 μm. A detailed morphological assessment of the main cardiac structures of the seventh heart was then performed.

RESULTS

Immersion in 2.5% I2KI solution for 48 hours was optimal for sample preparation. The optimal imaging conditions included a tube voltage of 100 kV, current of 150 μA, and exposure time of 354 milliseconds; scan duration was 12 minutes.

CONCLUSIONS AND CLINICAL RELEVANCE

Results provided an optimal micro-CT imaging protocol for excised cat hearts prepared with I2KI solution that could serve as a basis for future studies of micro-CT for high resolution 3-D imaging of cat hearts.

Authors: Yadu Goverdhan , Pateria M. Akash , Deshmukh K.
Published: March 2020

Ho doped Ag2S thin films were grown on the glass substrate by chemical bath deposition (CBD) method at room temperature. The bath contained aqueous solution of silver nitrate, thiourea, EDTA, ammonia and holmium nitrate. Silver nitrate was used as a silver (Ag+) ion source; thiourea as sulfur (S−) ion source, EDTA was a complexing agent while ammonia was used to maintain pH, Ho(NO3)3 was taken as a source of Ho ions. The optical absorption edge of undoped (pure) and Ho doped silver sulfide films was determined between 324 nm and 298 nm showing blue shift as compared to bulk Ag2S. Band gaps calculated from Tauc plot also showed an increase in values for doped samples. The increase in band gap indicates reduced particle size in the prepared Ho doped films. The photoluminescence emission peaks were observed at around 578 nm to 601 nm wavelength and excitation peaks were found at 351 nm to 294 nm for undoped and doped films. The SEM micrograph consists of globular ball type and flower type structures observed in the prepared films of Ho doped Ag2S.
English Straight and Tok Pisin Stret: A Case Study from the Perspective of Cognitive Linguistics
Authors: Kosecki Krzysztof
Published: March 2020

The framework of cognitive linguistics can be an efficient tool to represent the conceptual scope of meaning extension in reduced lexicons of pidgins and creoles. Image-schema based metaphors (Lakoff, 1993; Cienki, 1998) underlie the usage of English straight and its Tok Pisin counterpart stret, but the creole employs the concept in more contexts than English. The resultant variation in the scope of metaphor takes the form of a particular source domain being used to conceptualize more target domains than in the lexifier language. Functioning mainly as a compensation strategy, the variation is the effect of strong influence of English on the conceptual system of the creole.

Authors: Silisna Bet El , Susanti Retnaningtyas
Published: March 2020

This study aims to analyze the sport tourism event of Tour de Singkarak (TdS) related to tourist destination management in West Sumatera, Indonesia. The TdS is an international road bicycle race held annually for ten-year period as data presented from 2009 to 2018. Data were collected for this study through in-depth interviews with informants and analyzed by a descriptive qualitative technique. The results showed that the TdS events were succesfully and consistently held annually for ten-year period of 2009-2018 in West Sumatera and has significantly contributed to the regionas tourism destination. This was due to a strong commitment and serious action among central government and local government at province and municipality levels for the sport tourism development at the tourism destination in West Sumatera. The commitment could be seen in the serious, strong commitment and coordination between the Ministry of Tourism and the National Road Development Agency at a central government and Heads of Local Departments of Tourism, of Public Works and of Transportation at province and regency/municipality level. The commitment could be seen from the sport tourism management such as the provision of shared budget, event coordination, and destination and infrastructure development and promotion. This has especially raised an integrated development and improvement of infrastructures, i.e. roads, transportation mode, and accomodation facilities with increasing quantity and quality. It is a fact that TdS could be held annually for ten-year period (2009-2018) along with proper and good destination management for sport tourism in West Sumatera Province.

Prática docente frente às questões de gênero no cotidiano das aulas de educação física
Authors: Paixão Jairo Antônio , Ribeiro Camila Quintão
Published: March 2020

O estudo analisou a atuação de professores frente à categoria gênero nas aulas de Educação Física no ensino fundamental I e II, a partir de uma investigação de campo, descritiva e de cunho qualitativo, foram realizadas 40 sessões de observação sistemática de aulas e quatro entrevistas com quatro professores. Inferiu-se a prevalência de silenciamento das questões relacionadas a gênero na atuação indistinta de professoras e professores. Tal silenciamento se faz presente na forma de estruturação e condução das aulas, marcado pela ausência de equidade na participação de alunos e alunas nas atividades propostas nas aulas.

Esse trabalho objetiva investigar a contribuição das empresas transnacionaisno processo de inovação tecnológica do Complexo Agroindustrial brasileiro. Para isso,construiu-se um índice de internalização relativa da atividade tecnológica (IRAT), apartir de informações de depósitos de patentes (invenção e modelo de utilidade) eregistros de desenhos (desenhos e modelos industriais) no INPI. Foram analisadosdepósitos de 229 empresas, sendo 116 estrangeiras e 113 nacionais, agrupadas porsetores específicos e segmentos do CAI. Observou-se elevada concentração de patentesnas empresas estrangeiras e baixa internalização tecnológica no Complexo, para aspatentes de invenção (0,061), e maior internalização nos modelos de utilidade e registros(0,71). Considerando-se que os modelos de utilidade e registros têm teor tecnológicomais baixo, concluiu-se que é pouco significativa a contribuição das empresastransnacionais para a inovação tecnológica no CAI. Verificou-se maior internalização naagricultura do que no segmento a sua montante, que é mais sofisticado e intensivo nouso de tecnologias. Observou-se, também, que os setores de maior concentração deempresas estrangeiras apresentaram menores índices de internalização, e os de pequenaparticipação, maiores índices de internalização tecnológica. Assim, conclui-se que apresença de empresas estrangeiras nos setores e segmentos do CAI está inversamenterelacionada ao índice de internalização da atividade tecnológica.

Published: March 2020

Este artigo visou analisar o comportamento do comércio agrícola brasileirocom a União Européia (UE), em face das negociações para um acordo comercial entre oMercosul e a UE. Foram calculados os índices de vantagens comparativas reveladas(VCR) e de orientação regional (IOR), no período de 1991 a 2001, cujos produtosrelacionados foram soja e derivados, suco de laranja, fumo, frango, carne bovina, açúcare café. Em conjunto, esses produtos tiveram, no período assinalado, participação superiora 20% no total das exportações do Brasil, tendo a soja e derivados, o suco de laranjae o café maior participação nas exportações mundiais. À exceção do açúcar, todos osprodutos estudados tiveram a UE como importante destino das exportações. Os resultadosdo VCR expressam, em todos os produtos, maiores vantagens comparativas doBrasil, com valores estáveis ou crescentes ao longo da década. O IOR, por sua vez,ilustra a elevada orientação das exportações brasileiras para a UE, exceto para frango eaçúcar, mas que, em geral, não aumentaram no período. Em conseqüência, um acordoentre os blocos, reduzindo ou eliminando barreiras tarifárias e não-tarifárias, poderáresultar em criação de comércio, favorecendo as exportações agrícolas brasileiras comdestino à UE.

A atividade agrícola possui expressiva relevância para a agricultura da regiãoNorte. Em relação à modernização agrícola, as pesquisas são conduzidas de formaagregada (nacional), o que impossibilita verificar, efetivamente, qual o grau de desenvolvimentomunicipal e quais as variáveis que impactam este desenvolvimento. De formageral, pretende-se determinar o grau de modernização agrícola nos municípios do Norte.Observa-se que esta região apresenta baixos níveis estaduais de modernização, os quaisse justificam pela recente expansão da fronteira agrícola, pelo baixo nível de investimentosgovernamentais, pela falta de políticas públicas destinadas ao desenvolvimentoagrícola e, por fim, pelos movimentos ambientalistas.

Published: March 2020

Neste artigo procurou-se caracterizar e mensurar o complexo lácteo daeconomia do Estado do Rio Grande do Sul. A metodologia utilizou indicadores deperformance setorial e índices de autonomia de compras e vendas para delimitar amensuração do complexo lácteo. Os dados foram extraídos da matriz insumo-produtode 1998 disponibilizada pela FEE do RS. Verificou-se que o complexo lácteo gaúcho éum grande produtor de leite nacional e seu nível de competitividade o situa entre os maiseficientes produtores do país. O complexo lácteo responde, a preço básico, por 6,77%do PIB do agronegócio gaúcho está fortemente vinculado ao setor urbano de formadireta e emprega 118.603 trabalhadores, o que perfaz 5,07% e 2,42% do total detrabalhadores do agronegócio e do estado, respectivamente. A partir da parcela do valoradicionado apropriado pelos trabalhadores, identificou-se que a agroindústria do leitedetém processos produtivos modernos, com tecnologias mais intensivas no uso decapital que de mão-de-obra. Portanto, conclui-se que o complexo lácteo constitui-senum importante componente do agronegócio gaúcho e que seu desempenho, dados osfortes encadeamentos que apresenta com o setor urbano, é fundamental para o desenvolvimentoeconômico do estado.

Published: March 2020

Complex industrial systems often contain various uncertainties. Hence sophisticated fuzzy optimization (metaheuristics) techniques have become commonplace; and are currently indispensable for effective design, maintenance and operations of such systems. Unfortunately, such state-of-the-art techniques suffer several drawbacks when applied to largescale problems. In line of improving the performance of metaheuristics in those, this work proposes the fuzzy random matrix theory (RMT) as an add-on to the cuckoo search (CS) technique for solving the fuzzy large-scale multiobjective (MO) optimization problem; biofuel supply chain. The fuzzy biofuel supply chain problem accounts for uncertainties resulting from fluctuations in the annual electricity generation output of the biomass power plant [kWh/year]. The details of these investigations are presented and analyzed.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
An Enhanced Fault Tolerant Control Against Current Sensor Failures in Induction Motor Drive by Applying Space Vector

Published: March 2020

In this paper, an enhanced active fault-tolerant control (FTC) is proposed to solve a current sensor failure in the induction motor drive (IMD) using two current sensors. The proposed FTC method applies only one observer to diagnose the faults and reconfigure the control signals by the space stator current. The diagnosis function is made up of a comparison algorithm between the measured current space vector and the estimated space vector. Then, incorrect feedback stator currents are replaced by the estimated values in the reconfiguration function. The amplitude of a healthy measured current is applied to adjusted the accuracy of estimated current signals. The IMD uses the field-oriented control (FOC) technique to control the speed and torque. The effectiveness in stabilizing the IMD system when a current sensor error occurs is verified by various simulations in the Matlab-Simulink environment This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
Penetapan Kadar Fenolik dan Flavonoid Hasil Ultrasonic Assisted Extraction Daun Binahong (Anredera cordifolia [Ten] Steenis)
Authors: Sjahid Landyyun Rahmawan , Aqshari Amelia , Sediarso Sediarso
Published: March 2020

Anredera cordifolia [Ten] Steenis has been proven to have pharmacological activity that is thought to be influenced by the presence of phenolic compounds and flavonoids. However, both compounds are found in small concentrations through conventional extraction (maceration, decoction, soxhlet, and reflux). This study aims to prove that the ultrasonic assisted extraction method can obtain higher concentrations of phenolic and flavonoid compounds. Dried binahong leaves were extracted using ultrasonic assisted extraction with 70% ethanol. Phenolic levels were determined using Folin-Ciocalteu, while flavonoid levels were determined using the colorimetric aluminum method. The results showed binahong leaves ethanolic extract had phenolic levels of 10.16 % GAE and flavonoid levels of 10.58 % QE. These results are much higher than the results obtained using conventional extraction so that ultrasonic assisted extraction can be recommended to maximize the extraction of phenolic and flavonoid levels from the leaves of Binahong (Anredera cordifolia [Ten] Steenis).Â
Nuevas perspectivas sobre el precio de los medicamentos: El caso español
Authors: Cabiedes Miragaya Laura
Published: March 2020

Most developed countries regulate prices for on-patent drugs, especially if they are publicly funded. Although theoretical reasons -and therefore shared justification - sexist to intervene, pricing schemes may differ considerably from one country to another, as well as in the course of time. In fact, the current focus has been shifting away from cost considerations (the manufacturer´s perspective) towards value considerations (the user/society perspective). With the support of the current legislation and the scarce empirical evidence available to date, it was concluded that in Spain the intervention does not respond to a value-based pricing approach, namely, the prices of new drugs do not reflect their therapeutic value relative to existing alternatives. Besides, the Spanish case was compared with Sweden and the United States.

Authors: Ramírez Córcoles Yolanda , Santos Peñalver Jesús F.
Published: March 2020

Intellectual capital approach becomes critical at universities, mainly due to the fact that knowledge is the main output as well as input in these institutions. This prompted us to raise the need to disclose information on their intellectual capital. Our results represent a starting point for higher education institutions to identify what is the most requested information about intellectual capital, and therefore to develop an intellectual capital report. The logical conclusion of our study is the presentation of a proposal of intellectual capital report for Spanish universities.
