Authors: Sejati Bramasto Purbo , Dwiraharjo Bambang , Astuti Elizabeth Riyati Titi
Published: November 2021

Background: Glaucoma is characterized by optic neuropathy with increased intraocular pressure. The high prevalence of impaction causes some glaucoma patients to require odontectomy. There are no contraindications to odontectomy in glaucoma patients, but special preparation is needed to prevent recurrence during the procedure. Glaucoma recurrence is precipitated by increased intraocular pressure which correlates with elevated systemic blood pressure with increased intraocular pressure and corticosteroid use. Therefore, dentists must be vigilant in choosing an atraumatic odontectomy procedure, anesthetic dose and techniques, as well as administering the type and dose of analgesics. Objective: This paper reports a case of mandibular third molar odontectomy with local anesthesia in a patient with open-angle glaucoma, which is a rare case and in this case there is a high risk of complications. Case: A 26-year-old male patient complained of pain in the left back gum when chewing. Orthopantomographic radiographic examination showed impacted 38. The patient has been diagnosed with open-angle glaucoma for 5 years. An odontectomy was performed under local anesthesia. Durante surgery, bleeding is minimal and does not cause recurrence of glaucoma. Postoperative evaluation gave good results, minimal complications, and no recurrence of glaucoma.Conclusion: Odontontectomy with local anesthesia in glaucoma patients requires special preparation in the form of atraumatic surgical procedures and perioperative pharmacotherapy management in the form of pre-emptive analgesia, selection of a maximum of two ampoules of lidocaine and epinephrine 1:80,000 with the mandibular block anesthetic technique, and using multimodal analgesia in combination with NSAIDs without corticosteroids. Keywords: Complications, Glaucoma, Odontectomy

Authors: Diana Sherli , Yuliati Rizki Sri , Sukmana Bayu Indra
Published: November 2021

Background: The success or failure of root canal treatment is influenced by anatomical factors of the root canal, bacterial infection that causes inadequate hygiene, formation and filling of root canals, iatrogenic factors and several other factors. The average success of root canal treatment is 86-95%, while the failure of canal treatment ranges from 5-14%. Root canal re-treatment can be performed in the event of failure of root canal treatment. The method that can be used is gutta percha solvent. The gutta percha solvents used were Chloroform, Eucalyptol, Orange Oil, and Xylene, but chloroform has been categorized as a carcinogenic substance. Guta percha solvent can cause the intercrystalline distance to be larger, so that it can damage the apical density at obturation. This can create a gap between the gutta percha and the sealer which can cause apical leakage. Objective: To compare the value of apical leakage after root canal re-treatment between gutta percha solvent eucalyptol and orange oil. Method: The research method used is True Experimental with post-test only with control group design. A minimum sample of 8 teeth in a group. Total samples from all groups were 24 teeth. The teeth were stained using methylene blue and measured using stereomycroscopes. Results: the highest mean apical leakage was eucalyptol (4.55±2.59), xylene (2.77±1.94), and the lowest was citrus oil (2.20 ±1.06). The results of One-Way ANOVA test showed that there were no significant differences between orange oil, eucalyptol, and xylene (positive control). Conclusion: Eucalyptol has a higher average apical leakage value compared to orange oil and Xylene after root canal re-treatment as a gutta percha solvent. There was no significant difference between orange oil, Eucalyptol, and Xylene.Keywords: Apical leakage, eucalyptol, orange oil

Published: November 2021

Background: Several studies showed that fluoride interferes in the dynamics involved in the development of caries and could present an antimicrobial effect or provide demineralization inhibition or dental remineralization. The development of fluoride-releasing materials can contribute to a preventive of demineralization. GIC and Compomer are restorative materials containing fluoride which can prevent demineralization. Purpose: To analyze the effectiveness of Compomer and GIC against prevention in enamel demineralization. Method: The cavities were made on 18 bovine teeth which grouped into 3 groups, each group consisting of 6 bovine teeth. After the restorative procedures, the teeth were submitted to demineralization and remineralization cycling during 14 days. The sections of the teeth were examined under scanning electron microscope after undergoing pH cycling. The data were analyzed using the Kruskal-Wallis and Tukey Test (p<0.05). Results: GIC group showed the lowest lesion depth of demineralization (10.9883 ± 0.74333) followed by Compomer group (25.4183 ± 3.44268) and Control group (88.9783 ± 3.02495). Conclusion: GIC restorative materials have a better enamel demineralization prevention effect than Compomer. Keywords: compomer, demineralization, fluoride, GIC, remineralization

A Proof of the Riemann Hypothesis Based on A New Expression of the Completed Zeta Function
Authors: Zhang Weicun
Published: November 2021

The completed zeta function $\xi(s)$ is expanded in MacLaurin series (infinite polynomial), which can be further expressed as infinite product (Hadamard product) by its complex conjugate zeros $\alpha_i\pm j\beta_i, \beta_i\neq 0, i\in \mathbb{N}$. Then, according to the functional equation $\xi(s)=\xi(1-s)$, we have $$\xi(0)\prod_{i=1}^{\infty}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}\Big{(}1+\frac{(s-\alpha_i)^2}{\beta_i^2}\Big{)} =\xi(0)\prod_{i=1}^{\infty}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}\Big{(}1+\frac{(1-s-\alpha_i)^2}{\beta_i^2}\Big{)}$$ which, by Lemma 3 and Corollary 1, is equivalent to $$(s-\alpha_i)^2 = (1-s-\alpha_i)^2, i \in \mathbb{N}$$ with solution $\alpha_i= \frac{1}{2}, i\in \mathbb{N}$. Thus, a proof of the Riemann Hypothesis can be achieved.

Published: November 2021

This paper realizes early bearing fault warning through bearing fault time series prediction, and proposes a bearing fault time series prediction model based on optimized maximum correlation kurtosis deconvolution (MCKD) and long short-term memory (LSTM) recurrent neural network to ensure bearings operation reliability. The model is based on lifecycle vibration signal of the bearing, to begin, the cuckoo search (CS) is utilized to optimize the parameter filter length L and deconvolution period T of MCKD, taking into account the influence and periodicity of the bearing time series, the fault impact component of the optimized MCKD deconvolution time series is improved. Then select the LSTM learning rate α depending on deconvolution time series. Finally, the dataset obtained through various preprocessing approaches are used to train and predict the LSTM model. The average prediction accuracy of the optimized MCKD-LSTM model is 26 percent higher than that of the original time series, proving the efficiency of this method, and the prediction results track the real fault data well, according to the XI'AN JIAOTONG University XJTU-SY bearing dataset.
Food-Away-from-Home Expenditure in Mexico during the COVID-19 Pandemic: A Micro-Econometric Analysis
Authors: Aguilar-Lopez Antonio , Kuhar Aleš
Published: November 2021

The propagation of the coronavirus disease 2019 (COVID-19) reshaped the relationship between income and food-away-from-home (FAFH) expenditure in Mexico during 2020. Although the number of households participating in this market fell across income deciles and regions due to the pandemic, the impact on their budget shares is not uniform. Using data from the Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) 2020, we estimated an Engel curve of the Working-Lesser functional form for FAFH. Among the independent variables are the number of family members 65 years of age and older, and dummies to indicate whether the household experienced food insecurity or received remittances. The estimation was carried out following the Heckman two-step method, suitable for censored-response data. The results suggest that the budget share for FAFH drops as income increases. The number of older adults and food insecurity discourage the decision to participate in FAFH expenditure and increase its budget share, whereas remittances encourage participation and reduce its budget share. The corrected conditional elasticity is 0.4609; the sign and the magnitude indicate that FAFH is a necessity good.

Authors: DDS Alessandro Villa , Zollanvari Amin
Published: November 2021

Oral squamous cell carcinoma often arises from an oral potentially malignant disorder called oral leukoplakia (OL). With this work we aimed to develop a novel data-driven predictive model based on gene expression profiles to distinguish OL patients who underwent malignant transformation from those who did not. We used the Tree Augmented Naïve (TAN) Bayes classifier to predict the posterior probability of having oral cancer given the data. 86 patients were included with a median follow-up of 7.11 years. Fifty-one patients (51/86; 59%) underwent malignant transformation. We found that 16 genes were predictors of oral cancer in patients with OL and these included SLC7A11, SPINK6, SERPINA12, VIT, ATP1B3, CST6, FLRT2, ELMOD1, AZGP1, RNASE13, DIO2, ECM1, CYP4F11, SYTL4, AKR1C1, and AKR1C3. In conclusion, we showed that Bayesian gene networks are a data-driven approach which could be used also in other predictor models in oncology.

Nowadays, information security is a challenge especially when transmitted or shared in public clouds. Many of

researchers have been proposed technique which fails to provide

data integrity, security, authentication and another issue related

to sensitivity data. The most common techniques were used to

protect data during transmission on public cloud are cryptography,

steganography, and compression. The proposed scheme suggests an

entirely new approach for data security on public cloud. Authors

have suggested an entirely new approach that completely makes

secret data invisible behind carrier object and it is not been detected

with the image performance parameters like PSNR, MSE, entropy

and others. The details of results are explain in result section of

paper. Proposed technique have better outcome than any other

existing technique as a security mechanism on a public cloud.

Primary focus of suggested approach is to minimize integrity loss

of public storage data due to unrestricted access rights by uses. To

improve reusability of carrier even after data concealed is really a

challenging task and achieved through suggested approach.
Analysis on Spatio-temporal Characteristics and Influencing Factors of Industrial Green Innovation Efficiency——From the Perspective of Innovation Value Chain
Authors: Zhang Liyuan , Liu Pengzhen , Tarbert Heather
Published: November 2021

Green innovation has become an important combination of high-quality economic growth and sustainable development of ecological environment. In this paper, the super-efficiency network SBM model is used to measure the two-stage green innovation efficiency of industrial science and technology R&D and achievement transformation in 30 provinces and cities from 2009 to 2019, and exploratory Data Analysis (ESDA) and spatial econometric model are used to investigate the spatial-temporal evolution characteristics and influencing factors of green innovation efficiency. The results show that: firstly, the overall efficiency of industrial green innovation is low, and the efficiency of scientific research and development and achievement transformation has experienced three stages of "upward-declining-revitalized period". The low efficiency of achievement transformation is an important factor hiding the improvement of the efficiency of industrial green innovation. Secondly, The industrial green innovation efficiency gradually increases from northwest to southeast, forming a centralized "line" and "block" distribution. The high efficiency area is still concentrated in the eastern coastal region, and the balanced development trend is obvious in the central and western regions. Finally, openness has a positive impact on the two-stage green innovation efficiency; Industrial structure and government investment in science and technology have a positive impact on the efficiency of science and technology research and development, but have no significant effect on the efficiency of achievement transformation. Enterprise size has a positive effect on achievement transformation efficiency, but has no significant effect on R&D efficiency. Environmental regulation has a positive impact on R&D efficiency and a negative impact on achievement transformation efficiency.
Solving the Quintic: A New Approach to Bring's Transformation
Authors: Franco Jorge
Published: November 2021

Applying a procedure similar to that of E.S. Bring, by using a 4th degree Tschirnhaus transformation, it was possible to transform the Bring-Jerrard normal quintic (BJQ) equation into a De Moivre form (DMQ), so that it could be solved by radicals. The general solution by radicals of the De Moivre equations of any degree is presented. By the same procedure the BJSx (normal sextic) equation was taken to another one without the 2nd, 4th and 6th terms which was transformed into a cubic (solvable) equation. By applying a 6th degree Tschirnhaus transformation to the BJSp (normal septic) equation its binormal (without the 2nd, 3rd, 4th and 5th terms) form was obtained.

The Effect of Leukocyte Concentration on Platelet-Rich Plasma Injections for Knee Osteoarthritis
Authors: Abbas Aazad , Du Jin Tong , Dhotar Herman S.
Published: November 2021

Background:

It is hypothesized that leukocyte-poor (LP) platelet-rich plasma (PRP) is preferred over leukocyte-rich (LR) PRP for the treatment of knee osteoarthritis (OA).

Methods:

The MEDLINE, Embase, and Cochrane databases were reviewed for all English-language studies comparing LP-PRP or LR-PRP with relevant controls or each other. The follow-up periods were 6 months and 12 months. The primary outcome measure was the change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between baseline and follow-up. The secondary outcome measures were changes in the WOMAC pain subscale, visual analog scale (VAS) for pain, and International Knee Documentation Committee (IKDC) subjective score between baseline and follow-up, and the incidence of local adverse reactions. Treatment outcomes were analyzed using the mean difference between treatments for continuous outcomes and the odds ratio for binary outcomes, with 95% credibility intervals. Treatment modalities were ranked using the surface under the cumulative ranking (SUCRA) probabilities. Risk of bias was assessed using the relevant Cochrane tools, RoB 2 (version 2 of the Cochrane risk-of-bias tools) for randomized controlled trials (RCTs) and ROBINS-I (Risk of Bias in Non-Randomized Studies – of Interventions) for prospective comparative studies (PCSs).

Results:

This network meta-analysis included 23 studies: 20 RCTs and 3 PCSs, with a total of 2,260 patients and a mean follow-up period of 9.9 months. The overall risk-of-bias assessment of the RCTs revealed that 9 studies had low risk, 7 had some concerns, and 4 had high risk. The overall risk-of-bias assessment of the PCSs revealed that 1 study had low risk and 2 had moderate risk. We found no significant (p < 0.05) difference in all outcome measures and local adverse reactions between LP-PRP and LR-PRP. SUCRA rankings revealed that, for all outcome measures, LP-PRP is preferred to LR-PRP across follow-up periods.

Conclusions:

Leukocyte concentration of PRP does not play a significant role in patient-reported outcome measures for knee OA. LP-PRP is preferred to LR-PRP according to SUCRA rankings, but this preference may not be important in clinical practice.

Published: November 2021

De abordagem multidisciplinar, a imagem corporativa trata da imagem mental que o público tem sobre determinada organização. É considerada elemento estratégico, pois auxilia no direcionamento das ações de comunicação e no relacionamento entre a organização e seu público-alvo. O assunto é explorado no meio acadêmico, frequentemente direcionado às empresas, sendo a produção acadêmica ainda escassa no setor público. Assim, o presente estudo buscou verificar a produção acadêmica sobre a “imagem corporativa no setor público”, por intermédio de uma revisão sistemática. Dentre os principais resultados destaca-se o fato da “imagem corporativa no setor público” ser uma temática atual, porém com publicações irregulares ao longo dos anos, sem autores proeminentes e de metodologia majoritariamente qualitativa. Percebe-se a necessidade de ampliação de estudos específicos de imagem corporativa no setor público, além de estudos de caso do desdobramento destes, explicitando as ações organizacionais referentes à comunicação que possam melhorar a imagem percebida.

Esta pesquisa estuda a convergência perceptiva dos consumidores na compra de perfumes, considerando-se os quatro sentidos (olfato, visão, tato e audição (influências sociais)). A convergência perceptiva foi determinada como variável dependente, e cada sentido, uma variável independente. Realizou-se um levantamento com 321 respondentes, evidenciando a influência dos construtos sensoriais do consumidor. As correlações mais fortes foram entre "percepção olfativa" e "audição" (imagem social do perfume) e "cheiro" e "toque". As menores correlações foram "visão" e "cheiro". A convergência sensorial é melhor explicada pelos construtos "cheiro" e "toque", enquanto a "visão" e a "audição" (sugestões de perfume), não indicaram fortes contribuições. Constatou-se a importância da análise de convergência sensorial no setor de perfumaria, tanto em investigações científicas quanto na indústria. Recomenda-se a utilização de neurotecnologias para se obter conhecimento sobre influências neurossensoriais, por exemplo a neuroplasticidade, nas experiências sensoriais em perfumes, produtos alimentícios, bebidas, fármacos, varejo, entre outras possibilidades de marketing.

In 2020, PCSB implemented the first permanent Plug & Abandonment (P&A) campaign for three Subsea wells in a gas field offshore Malaysia. The main objective of the campaign was to establish two (2) barriers for every movable hydrocarbon or overpressure bearing sand by placing laterally extended cement plug across impermeable formation with enough formation strength to handle the pressure of the formation to be isolated. The unique case of this operation was the challenges to execute PCSB's first subsea P&A operation in gas field Malaysia during pandemic situation. In March 2020, the Malaysian government imposed Movement Control Order (MCO) to curb the spread of the COVID-19. A semi-submersible rig was on-hired a week after government initiated the MCO, resulted in the rig preparation being badly hampered due to manpower management and material fabrication and delivery. PCSB was exposed to expensive rig daily rate that had to be managed. Four (4) main challenges were encountered during operation: safe protection for workers, expensive standby cost, manpower management and material fabrication and delivery. This paper, from the ‘project management’ point of view, describes the journey of managing rig operation during PCSB's first subsea wells P&A in Malaysia efficiently amidst the pandemic by reducing the impact of COVID-19 on project cost. With the experience of managing rig for subsea well operation, a complex operation in Malaysia, amidst pandemic, PCSB sharing on the experience is beneficial to provide context setting and benchmark on maintaining the efficiency of operation. Wells successfully met the objective of operation with no incident occurred, negotiated reduction on standby cost and managed to bring critical manpower on time during operation.

Published: November 2021

Abandonment is considered to be the last stage in the oil gas field cycle. Oil and gas industries around the world are bounded by the necessity of creating an abandonment program which is technically sound, complied to the stringent HSE requirement and to be cost-effective. Abandonment strategies were always planned as early as during the field development plan. When there are no remaining opportunities left or no commercially viable hydrocarbon is present, the field need to be abandoned to save operating and maintenance cost. The cost associated on abandonment can often be paid to the host government periodically and can be cost recoverable once the field is ready to be abandoned.

In Malaysia, some of the oil producing fields are now in the late life of production thus abandonment strategies are being studied comprehensively. The interest of this paper is to share the case study of one of a field that is in its late life of production and has wells and facilities that planned to be abandon soon. The abandonment in this field is challenging because it involves two countries, as this field is in the hydrocarbon structure that straddling two countries. Series of techno-commercial discussion were held between operators of these two countries to gain an integrated understanding of the opportunity, defining a successful outcome of the opportunity and creating an aligned plan to achieve successful abandonment campaign. Thus, this paper will discuss on technical aspects of creating a caprock model, the execution strategies of abandoning the wells and facilities and economic analysis to study whether a joint campaign between the operators from two countries yields significantly lower costs or otherwise.

Published: November 2021

More than a thousand fixed oil and gas offshore structures were installed in the Southeast Asia region. Indonesia currently has more than 600 offshore oil and gas platforms, nearly half of which need to be decommissioned within the next few years. While the regulators and operators are developing procedures and regulations for the decommissioning process of the offshore platforms, there is also a need to ensure that onshore facilities are available to receive the decommissioned structures and equipment and subsequently process them safely. At the moment, there is no yard in Indonesia that is well-placed to undertake onshore decommissioning activities. The aim of this study is to develop recommendations for yard owners to assure their yards are ready for the upcoming decommissioning projects. Research data was collected directly from field survey in an offshore fabrication yard, owned by PT. Meitech Eka Bintan, Indonesia. In the current study, research data was analyzed by comparing with decommissioning yard facilities in ABLE Seaton Port, United Kingdom which was used as offshore structure decommissioning yard since 1985. Recommendations include the work required to assure the yard comply with respective guidelines and industry best practices. The research begun with identifying the yard's potential to receive onshore decommissioning work based on current primary facilities which are quay and fabrication area properties. After that, a yard modernization assessment was carried out as to identify the best location for the upgrade on the missing required facilities. The results indicate that the primary facilities of the yard are comparable to ABLE Seaton Port with both having similar depth at quayside, capable of mooring barges and Heavy Lift Vessel (HLV), both having liquid containment system at the fabrication area and the large fabrication area at PT. Meitech Eka Bintan yard is sufficient similar to the area utilized by ABLE Seaton Port for Brent Delta topside decommissioning works. However, since the yard's main business is currently on offshore structure fabrication, hence there is a lack of waste handling facilities such as waste handling workshop and covered waste storage area to fulfill the respective guidelines and regulations. A case study was carried out to identify the onshore decommissioning working area and the location of the waste handling facilities on the yard. This study is expected to assist towards improving the readiness of yards to carry out onshore decommissioning not only in Indonesia but also in Southeast Asia region.

Mercury present in produced oil and gas will deposit onto the internal process infrastructure via a number of mechanisms including chemisorption and adsorption with the primary mechanism being through reaction with iron sulphide to form mercury sulphide. Due to the volumes of fluids produced and the length of time facilities are in production, even where the produced fluids have historically contained relatively low concentrations of mercury, pipeline scales containing percentage levels of mercury may be present.

Thus, aged facilities and infrastructure that have reached the end of their operational life and are selected for either recycling or abandonment, may pose a serious risk to health and the environment if the decommissioning process is not managed correctly. Smelting, hot cutting or other thermal/abrasive surface preparations for example, can lead to significant release of elemental mercury, a worker exposure hazard. Alternatively, if sub-sea pipelines are abandoned in-situ, all mercury present will ultimately be transferred to the local ecosystems. Consequently, the oil and gas industry have the requirement for a complete mercury decontamination solution from initial evaluation, demonstrable cleaning efficacy through to a guarantee for the treatment and disposal of the mercury waste generated in an environmentally-friendly manner.

In order to decide upon the most appropriate decontamination solution, an evaluation of the extent of mercury contamination should be undertaken. A novel approach that has recently been successfully implemented involved analysis of pipe sections by multiple analytical techniques, providing the mercury concentration in the scale/steel. From this, the total mass of mercury across the process or pipeline was approximated.

Subsequently, the efficacy of the preferred chemical to remove mercury from the internal surfaces of pipework was evaluated by chemical treatment of the pipe sections under laboratory conditions.

In-situ decontamination can be performed by a number of applications, including (i) the use of chemical pig trains in pipelines, (ii) closed loop circulation of chemical around topside process equipment and (iii) high pressure spraying of large surface areas such as storage tanks, FSO / FPSO vessels. The mercury waste generated is treated, on site or off site, to minimise the volume and disposed of in accordance with international regulations.

An all-encompassing mercury decontamination solution is described. Trials involving the chemical treatment of steel sections have demonstrated that more than 97% of the mercury deposited can be removed from the internal surfaces of pipelines and safely disposed of, significantly reducing the risk of (i) mercury release to the environment and (ii) worker exposure to mercury during smelting activities.

No atual cenário educacional é imprescindível o planejamento das atividades didáticas que norteiam o caminho para uma educação de qualidade, auxiliando no ensino-aprendizagem de maneira significativa. No entanto, no ensino das ciências naturais, especificamente no ensino de física, é verificado uma dependência excessiva do livro didático e de aulas expositivas. Assim, foi proposto uma sequência didática a fim de potencializar o ensino de óptica geométrica em uma turma de graduação, utilizando técnicas de gamificação para auxiliar na formação de um aluno mais crítico e reflexivo. Para realizar essa pesquisa de caso, utilizamos: roteiro didático para simulação virtual, palavras cruzadas, Quiz conceitual e listas de exercícios. Ao final, foi aplicado um questionário tendo como objetivo mapear o impacto da aplicação da sequência didática no ensino de óptica geométrica. Verificou-se que a sequência didática gamificada correspondeu aos resultados esperados, proporcionando uma maior participação e envolvimento entre os alunos. Tendo a motivação, como elemento fundamental para alcançar os objetivos de maneira prazerosa e atrativa. Vale ressaltar, que os instrumentos da sequência obtiveram grande aceitação entre os alunos, apontando as palavras cruzadas como instrumento eficaz na revisão conceitual, os quizzes como prática lúdica e motivadora e a importância da utilização da simulação virtual pela autonomia nas mudanças de configurações do sistema sem oferecer risco a si ou ao equipamento. Por isso, essa pesquisa mostra a necessidade de esforços teóricos/práticos que contribuam para a legitimação e ampliação de estratégias gamificadas no ensino de física.

A Olimpíada Brasileira de Robótica é uma competição entre estudantes, na qual um dos desafios é que os robôs capturem esferas dispostas numa sala. Este trabalho propõe uma solução para esse problema utilizando visão computacional e redes neurais artificiais, as quais fornecem como saída final um vetor contendo a localização do ponto do centro da esfera mais próxima e seu raio na imagem. Isso permite que os pontos que delimitam a esfera sejam determinados. O modelo obtido ao final do trabalho em um computador de uso geral foi satisfatório, obtendo uma acurácia de detecção de aproximadamente 90%. Para seu desenvolvimento, foi utilizado um banco de dados com 1440 imagens de situações possíveis com as quais o robô pode se deparar. A rede já foi testada numa possível placa a ser embarcada, porém resta ainda fazer os testes em um robô real.

A análise das competências essenciais possibilita definir um foco e direcionar esforços em tarefas específicas que geram vantagens competitivas, agreguem valor e proporcionam o crescimento da empresa dentro de parâmetros difíceis de serem copiados pelos concorrentes. O destino das organizações será definido com base em conceitos e valores estabelecidos por elas, dado o reconhecimento e a valorização das competências essenciais, influenciando nas mudanças de paradigmas e na evolução da sociedade empresarial. Dessa forma, compreender as competências essenciais consiste em conhecer melhor a própria organização, seus pontos fortes e, principalmente, identificar os diferenciais da empresa. A partir daí, será possível definir estratégias de gestão que potencializam a capacidade competitiva de acordo com as necessidades do mercado. Toda empresa possui características que a diferem das demais, são detalhes que influenciam o consumidor no momento de escolher determinada organização em comparação a outras do mesmo segmento. Assim, são justamente os conceitos desses “detalhes” que serão apresentados neste trabalho, verificados em uma microempresa por meio de pesquisa de campo e aplicação de 40 questionários a clientes, partindo da hipótese de que essas competências essenciais são responsáveis pelos bons resultados e pela sobrevivência dos negócios. Concluiu-se que a empresa possui vantagens competitivas, mas não competências essenciais.

Considerando que o descarte de óleos e gorduras causa diversos impactos negativos, especialmente com a poluição da água, do solo e impactos sobre a infraestrutura de saneamento, é necessário que a população tome conhecimento das formas de reuso e destinação adequados desse resíduo. Assim, este trabalho teve como objetivo promover a mudança de hábitos dos sujeitos residentes em um condomínio da cidade de Fortaleza a partir de um treinamento e da realização de um diagnóstico do volume e forma de descarte de óleos e gorduras residuais por parte dos contemplados. Foi realizado o cálculo amostral, resultando em 35 pessoas para amostra desta pesquisa. Foi aplicado um questionário com 10 questões onde foram avaliados a idade, a escolaridade, o volume de óleos gerados por residência e a percepção dos participantes sobre os impactos e forma correta de descarte dos Óleos e Gorduras Residuais (OGR). Depois desse levantamento, foi realizada uma oficina para explicar as formas de disposição correta e os impactos do descarte no solo ou nas pias. Foi aplicado um segundo questionário para avaliar o aprendizado dos participantes. Estima-se que sejam gerados 46,5 litros de OGR por mês nas residências participantes que, se descartado de forma incorreta, podem poluir 930.000 litros de água. A oficina teve um impacto positivo na mudança de atitude dos participantes, visto que os moradores reduziram o descarte no solo e no ralo em 11% e houve um aumento de 17% na doação de OGR.

Desde a primeira década do século XXI, há consideráveis avanços em procedimentos de doação de órgãos realizados pelo SUS no Brasil, porém, a demanda por doações ainda é superior à oferta de órgãos. O objetivo deste artigo é descrever e analisar os principais fatores que exercem influência na intenção de doar órgãos segundo a percepção de indivíduos doadores, não doadores e potenciais doadores. A pesquisa é quantitativa, onde 581 participantes responderam ao questionário estruturado , cuja análise foi feita pela Modelagem de Equações Estruturais. O modelo final apresentou como construto dependente a ‘Intenção de doar órgãos’, que é influenciado pela ‘Norma subjetiva’ e pela ‘Atitude relacionada à doação de órgãos’, e apresentou influência dos construtos ‘Atitude relacionada à doação de órgãos em vida’ e ‘Campanhas de marketing social’. O construto ‘Campanhas de marketing social’ apresentou uma considerável dependência do ‘apelo das campanhas’. Concluiu-se, portanto, que a intenção de doar órgãos pode ser compreendida como um construto de elevada carga emocional, no qual o altruísmo e a possibilidade de se reestabelecer uma vida a partir da doação se fazem presentes.
