Efficiency and productivity change of public hospitals in Panama: Do management schemes matter?
Authors: Cordero Jose M. , García-García Agustín , Lau-Cortés Enrique , Polo Cristina
Published: July 2020

Background
In Latin American and Caribbean countries the main concern of public health care managers has been traditionally placed on problems related to funding, payment mechanisms and equity of access. However, more recently, there is a growing interest in improving the levels of efficiency and reducing costs in the provision of health services. In this paper we focus on measuring the efficiency of public hospitals in Panama, where no such studies have been conducted so far. One of the most interesting features of the public hospital system in this country is that there are two different management schemes that coexist, thus we can make a distinction between hospitals operating under the Social Security Fund (SSF) and those belonging to the Ministry of Health (MoH).
Methods
Our dataset includes data about 22 public hospitals (11 for each model) during the period 2005–2015. We rely on the use of Data Envelopment Analysis and the Malmquist Productivity index to calculate technical efficiency and productivity change of hospitals. In addition, we also apply bootstrapping techniques to calculate confidence intervals for the obtained efficiency and productivity scores in order to obtain more robust results.
Results
We find that, until the period 2012–2013, the performance of hospitals belonging to different systems experienced a similar trend. However, during the last years of the evaluated period the hospitals operating under the Social Security Fund clearly outperformed Ministry´s hospitals. The main explanation for these divergences seems to be the growth of technological change. Nevertheless, the use of bootstrapping to make statistical inferences reveals that some differences detected may not be significant.
Conclusion
We demonstrate that the results of traditional DEA and Malmquist index analyses need to be tested for statistical significance. Otherwise, the conclusions reached could be wrong.

Age-related degeneration of lung tissues increases the risk of lung injury and exacerbates lung disease. It is also the main risk factor for chronic lung diseases (such as COPD, idiopathic pulmonary fibrosis, cancer, etc.). Here, we performed systematic screening, evaluation of elderly macaque model. A senile multiple organ dysfunction model was used to explored whether BMMSC could improve degeneration of lung tissues in an elderly macaque model. Using model evaluation tests, we found that the average alveolar area, Mean linear intercept（MLI） and fibrosis area in the elderly macaque models were significantly larger than in young rhesus monkeys (P <0.05), and the capillary density around the alveoli was significantly lower than in young macaque models (P <0.05). Intraveous infusion of BMMSC reduced the degree of pulmonary fibrosis in elderly macaque, increased the density of capillaries around the alveoli (P <0.05), and the number of type Ⅱ alveolar epithelium in elderly macaque (P <0.05). BMMSC infusion reduced lung tissue ROS level, systemic and lung tissue inflammation level and Treg cell ratio in elderly macaque model（P＜0.05）. Indirect co-cultivation revealed that BMMSC reduced the expression of senescence-related genes, ROS levels, apoptosis rate of aging type Ⅱ alveolar epithelial cells (A549 cells) and promoted their proliferation (P＜0.05).

Authors: Chen Yeye , Liu Lei , Huang Cheng , Tian Zhenhuan , Liu Hongsheng , LI Shanqing
Published: July 2020

Background: Small-cell lung cancer (SCLC) patients are generally not considered to be candidates for surgical intervention. The role of surgery in the multidisciplinary treatment of SCLC remains controversial. The study aims to summarize and analyse the clinical characteristics and prognosis of SCLC patients after surgical treatment and identify the related prognostic factors.Methods: The clinical data of 130 SCLC patients (99 males and 31 females) who were treated by surgery and confirmed by postoperative pathological examination in Peking Union Medical College Hospital from April 2004 to April 2019 were analysed retrospectively.Results: The median age was 60 years (30-83 years), and the median disease duration was 2 months (0.5-48 months). The patients did not have specific clinical or imaging manifestations. Postoperative pathological examination revealed that 36 patients had stage I, 22 patients had stage II, 65 patients had stage III, and seven patients had stage IV SCLC. The median overall survival time was 50 months (95% confidence interval, 10.8-89.2 months). The median survival time of stage I, II, III, and IV SCLC patients were 148 months, 42 months, 32 months, and 10 months, respectively. In patients who underwent surgical treatment, postoperative adjuvant therapy and tumour stage were two significant influencing factors of survival (Cox multivariate analysis P < 0.05).Conclusions: Surgical treatment combined with adjuvant therapy can achieve satisfactory outcomes in selected SCLC patients. Adjuvant therapy and tumour stage are independent risk factors. Surgical treatment is indicated in SCLC patients preoperatively staged as I-IIIa, and anatomical lobectomy and lymphadenectomy combined with postoperative adjuvant therapy are recommended.

Authors: Huang Guichuan , Zhang Jing , Gong Ling , Huang Yi , Liu Daishun
Published: July 2020

Purpose: Lung cancer is one of the most lethal and most prevalent malignant tumors worldwide, and lung squamous cell carcinoma (LUSC) is one of major histological subtypes. Although, numerous biomarkers were found to be associated with prognosis in LUSC, the prediction effect of a single gene biomarker is not sufficient, especially for glycolysis-related genes. Therefore, we aimed to develop a novel glycolysis-related gene signature to predict survival of patients with LUSC. Material and Methods: The mRNA expression files and clinical information of LUSC were obtained from The Cancer Genome Atlas (TCGA) dataset. Results: Based on Gene set enrichment analysis (GSEA), we found 5 glycolysis-related gene sets were significantly enriched in LUSC tissues. Univariate and multivariate Cox proportional regression models were conducted to choose prognostic-related gene signature. Based on Cox proportional regression model, a risk score of three-gene signature (including HKDC1, ALDH7A1, and MDH1) was established to divide patients into high-risk and low-risk subgroups. We found that a risk score of three-gene signature was an independent of prognostic indicator in LUSC using multivariate Cox regression analysis.Conclusion: In conclusion, a glycolysis-based three-gene signature could serve as a novel biomarker in predicting prognosis of patients with LUSC, which provided more gene targets to cure LUSC patients.

Published: July 2020

Background: The percentage of death resulted from hepatocellular carcinoma (HCC) remains high worldwide, despite surgical and chemotherapy treatment. Immunotherapy offers great promise in the treatment of a rapidly expanding spectrum of HCC. Therefore, further exploration of the immune-related signatures in the tumor microenvironment, which plays a vital role in tumor initiation and progression for immunotherapy is currently needed. Methods: In this present research, 866 immune-related difference expression genes (DEGs) were identified by integrating the DEGs between TCGA HCC and normal tissue and the immune genes from databases (Innate DB; Imm Port), and 144 candidate prognostic genes were defined through weighted gene co-expression network analysis (WGCNA). Results: Seven prognostic immune-related DEGs were determined with LASSO Cox PH model, which was followed by constructing the ImmuneRiskScore model based on the prognostic immune-related DEGs. The prognostic index of the ImmuneRiskScore was validated then in the dependent dataset. Patients were divided into high- and low-risk groups according to ImmuneRiskScore. The difference in ImmuneRiskScore and infiltration of immune cells between groups was detected and the correlation analysis for immunotherapy biomarkers was further explored. Conclusion:The ImmuneRiskScore of HCC could provide a prognostic signature and reflect immune characteristics within tumor microenvironment. Furthermore, it also may provide novel immunotherapy predictive biomarker for HCC patients in the near future.
Undirected graphs: is the shift-enabled condition trivial or necessary?
Authors: Chen Liyan , Cheng Samuel , He Kanghang , Stankovic Vlandimir , Stankovic Lina
Published: July 2020

It has recently been shown that, contrary to the wide belief that a shift-enabled condition (necessary for any shift-invariant filter to be representable by a graph shift matrix) can be ignored because any non-shift-enabled matrix can be converted to a shift-enabled matrix, such a conversion in general may not hold for a directed graph with non-symmetric shift matrix. This paper extends this prior work, focusing on undirected graphs where the shift matrix is generally symmetric. We show that while, in this case, the shift matrix can be converted to satisfy the original shift-enabled condition, the converted matrix is not associated with the original graph, that is, it does not capture anymore the structure of the graph signal. We show via a counterexample, that a non-shift-enabled matrix cannot be converted to a shift-enabled one and still maintain the topological structure of the underlying graph, which is necessary to facilitate localized signal processing.
Why do clinicians overtest? A narrative review and workshop group discussion exploring influences on clinician overtesting as possible causes of overdiagnosis
Authors: Lam Justin H , Pickles Kristen , Stanaway Fiona , Bell Katy JL
Published: July 2020

Background: Screening and diagnostic tests provide important information to guide clinical management. Overtesting however may cause harm to patients and the healthcare system, including through overdiagnosis. Clinicians are ultimately responsible for test requests, and therefore are ideally positioned to prevent overtesting and overdiagnosis. Through this narrative literature review followed by group discussion at a conference workshop (Preventing Overdiagnosis Conference [PODC], Sydney, 2019), we aimed to identify and categorise factors that influence clinicians to request potentially unnecessary screening and diagnostic tests that could result in overdiagnosis.Methods: Articles exploring factors affecting clinician test ordering behaviour were identified through a systematic search of MedLine in April 2019, forward and backward citation searches and content experts. Two authors screened abstract titles and abstracts, and two authors screened full text for inclusion. Identified factors were categorised into a preliminary framework which was subsequently presented at the PODC for iterative development.Results: The MedLine search yielded 542 articles; 55 were included. Another 10 articles identified by forward-backward citation and content experts were included, resulting in 65 articles in total. Following small group discussion with workshop participants, a revised thematic framework of factors was developed: ● “Interpersonal” – pressure from colleagues and medical culture; pressure from patients and doctor-patient relationship● “Contextual” – clinician knowledge and understanding; cognitive biases and experiences; contemporary medical practice and new technology● “Environmental or workplace” – guidelines, protocols and policies; financial incentives; time constraints, physical vulnerabilities and language barriers; pre-emptive testing to facilitate subsequent care; availability, ownership and ease of access to tests● “Intrapersonal” – fear of malpractice and litigation; intolerance of uncertainty and risk aversion; sense of medical obligation Conclusion: Through this thematic framework, clinicians can become more aware of their test ordering behaviour and feel empowered to limit overtesting and overdiagnosis. This framework may also guide the development of a scale assessing clinician knowledge, attitudes and practices around overtesting and overdiagnosis, to facilitate measurement of the effects of clinician-targeted interventions to prevent overdiagnosis.

Published: July 2020

ObjectiveWe have developed a fully automatic three-dimensional MRI analysis software that measures the projected cartilage area ratio (PCAR) to allow for the quantification of the cartilage in the knee. Our objectives were to verify our software’s accuracy for segmentation of cartilage and meniscus and to quantify cartilage and meniscus extrusion in our cross-sectional study. We also examined which cartilage quantification was most affected by age and analyzed the relationship between PCAR and meniscus extrusion.MethodsMRI data from 108 subjects were selected for training, and Dice similarity coefficients were determined from 5 other subjects to verify the accuracy. Our cross-sectional study included other 561 subjects between 30–70 years of age. We quantified cartilage thickness, cartilage volume, and PCAR (0.0–1.5 mm) in medial femoral, lateral femoral, medial tibial, and medial lateral regions. Each region was divided into nine subregions, with particular focus on the medial central (mc) subregion. The medial meniscus coverage ratio (MMCR) was investigated as a quantification for meniscus extrusion.ResultsDice similarity coefficients for cartilage and meniscus were both approximately 0.9. Among cartilage quantifications, the highest absolute value of the correlation coefficient with age was mcMT PCAR 1.0 mm in females and mcMT cartilage thickness in males. In females, mcMT PCAR 1.0 mm was correlated with MMCR, although MMCR was not correlated with age. In males, mcMT PCAR 0.0 mm was correlated with MMCR.ConclusionsOur software showed high segmentation accuracy and provided numerous quantifications of cartilage related to age and meniscus extrusion.Trial registration: UMIN, UMIN000032826.

Published: July 2020

The public’s actions will likely have a significant effect on the course of the coronavirus disease (COVID-19) pandemic. Human behavior is conditioned and shaped by information and perceptions of people. This study investigated the impact of risk perception on trust in government and self-efficacy. It examined whether the use of social media helps people adopt preventative actions during the pandemic. To test this hypothesis, data were gathered from 512 individuals (students and academicians) who were based in Malaysia during COVID-19. Our results suggested that risk perception had a significant effect on trust in government and self-efficacy. Moreover, these correlations were stronger when social media was used as a source for gathering information on COVID-19, and in some cases it even helped the user avoid being exposed to the virus. This study assessed the relationship between risk perception and the awareness gained from using social media during the pandemic and also highlighted how social media usage influences trust in government and self-efficacy.
THE IMPACT OF INDIVIDUAL STUDENT MENTORING FOR TEACHER PROFESSIONALISM IN ENGLISH PRESERVICE TEACHER EDUCATION
Authors: Wati Mega -
Published: July 2020

Mentoring in preservice education is a key success factor, because not only can it transform the preservice teacher as the mentee, but also develop the mentor teacher professionally. This prelimenary study to find the impact of individual student mentoring was inspired by the awareness of  its potential multidimentional impact for teacher professionalism. Two research questions guided this study. The first question is to find out the impact of this individual student mentoring from the student mentee’s point of view in terms of four dimensions, namely: psychological or emotional support, support for setting goals and choosing a career path,  academic subject knowledge support, and a role model. The second research question explores how this kind of mentoring developed the mentor teacher professionally. Data were collected from the students in the form of questionaire and written reflection, and from the mentor teacher in the form of written reflection. Data were analyzed separately to attend to each reseach question. The findings show that the preservice students experienced the four dimensions in their individual mentoring, while the mentor teacher developed herself professionally in 3 areas, which were interactional skills, self-awareness, and attitude. The implication of the findings is discussed at the end.

Published: July 2020

Background:

Resistance to antimicrobial agents is a major public health problem, being Staphylococcus aureus prevalent in infections in hospital and community environments and, admittedly, related to biofilm formation in biotic and abiotic surfaces. Biofilms form a complex and structured community of microorganisms surrounded by an extracellular matrix adhering to each other and to a surface that gives them even more protection from and resistance against the action of antimicrobial agents, as well as against host defenses.

Methods:

Aiming to control and solve these problems, our study sought to evaluate the action of 1,2,3- triazoles against a Staphylococcus aureus isolate in planktonic and in the biofilm form, evaluating the activity of this triazole through Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) tests. We have also performed cytotoxic evaluation and Scanning Electron Microscopy (SEM) of the biofilms under the treatment of the compound. The 1,2,3-triazole DAN 49 showed bacteriostatic and bactericidal activity (MIC and MBC 128 μg/mL). In addition, its presence interfered with the biofilm formation stage (1/2 MIC, p <0.000001) and demonstrated an effect on young preformed biofilm (2 MICs, p <0.05).

Results:

Scanning Electron Microscopy images showed a reduction in the cell population and the appearance of deformations on the surface of some bacteria in the biofilm under treatment with the compound.

Conclusion:

Therefore, it was possible to conclude the promising anti-biofilm potential of 1,2,3-triazole, demonstrating the importance of the synthesis of new compounds with biological activity.
Simultaneous Determination of Ultra-trace Pt, Pd, Rh and Ir in Geochemical Samples by Inductively Coupled Plasma Mass Spectrometry Following Tin Fire Assay Preconcentration and Microwave Digestion
Authors: Ni Wenshan , Mao Xiangju , Zhang Hongli , Liu Lu , Guo Xiaorui , Sun Qiliang
Published: July 2020

Background:

Platinum (Pt), palladium (Pd), rhodium (Rh) and iridium (Ir) are platinum
group elements (PGEs) and also important elements of geochemistry and environmental chemistry
with the similar physic-chemical properties, which have been widely used in industry and laboratory.
However, due to the low abundance and inhomogeneous distribution in natural ore as well as the
nugget effect, the accurate determination of PGEs has been a challenge to analytical chemistry.

Methods:

In this work, a novel fire assay method was reported for the determination of ultra-trace Pt,
Pd, Rh and Ir in geochemical samples. Tin powder (Sn) instead of stannic oxide (SnO2) was used as a
fire assay collector to reduce the melting temperature from 1250°C to 1050°C, the escape of molten
material caused by high temperature was successfully avoided. Tin bead was compressed into thin
slice and dissolved by HCl. For the target Pt, Pd, Rh and Ir, HCl insoluble substance such as PtSn4,
PdSn4, RhSn4 and Ir3Sn7 were formed and separated from matrix by filtering. The metal compounds
precipitate together with filter paper were microwave-assisted completely digested by aqua regia
(50%, v/v), thence the sample solution was determined by inductively coupled plasma mass spectrometry
(ICP-MS).

Results:

Compared with nickel oxide and lead oxide in nickel sulfide /lead fire assay, the reagent
blank of tin powder were relatively low and could be directly employed in tin fire assay to collect Pt,
Pd, Rh and Ir without purifying. Moreover, the harm of nickel oxide and lead oxide to the analyst
and environment was avoided by using the non-toxic tin powder. The decomposition method of
chromite and black shale was investigated as well as the amount of tin powder and flour, microwave
digestion program for the determination of Pt, Pd, Rh and Ir were optimized. Besides, the influence
of mass spectrum interference of co-existing elements was discussed and the standard mode and kinetic
energy discrimination collision pool mode were compared. Under the optimal conditions, excellent
curve fitting of Pt, Pd, Rh and Ir were obtained between 0.01~100 ng mL-1, with the correlation
coefficients exceeding 0.9996. The detection limits were from 0.003 ng g-1 to 0.057 ng g-1.

Conclusion:

The developed method was applied to analyze the Chinese Certified Reference Materials
and the determined values were in good agreement with the certified values.
Task Scheduling Algorithm Based on Reliability Perception in Cloud Computing
Authors: Yuejuan Kuang , Zhuojun Luo , Weihao Ouyang
Published: July 2020

Background:

In order to obtain reliable cloud resources, reduce the impact of resource
node faults in cloud computing environment and reduce the fault time perceived by the application
layer, a task scheduling model based on reliability perception is proposed.

Methods:

The model combines the two-parameter weibull distribution and analyzes various interaction
relations between parallel tasks to describe the local characteristics of the failure rules of resource
nodes and communication links in different periods. The model is added into the particle
swarm optimization (PSO) algorithm, and an adaptive inertial weighted PSO resource scheduling
algorithm based on reliability perception is obtained.

Results:

Simulation results show that when A increases to 0.3, the average scheduling length of the
task increases rapidly. When it is 0.4-0.6, the growth rate is relatively slow. When greater than 0.8,
the average scheduling length increases sharply, it can be seen that the r-PSO algorithm proposed in
this paper can accurately estimate the relevant parameters of cloud resource failure rule, and the
generated resource scheduling scheme has better fitness, and the optimization effect is more significant
with the increase in the number of tasks.

Conclusion:

With only a small amount of time added, the reliability of cloud services is greatly
improved.

Published: July 2020

This research was conducted to discover Vibrio harveyi infected vannamei shrimp with White Feces Disease (WFD) in Situbondo, East Java Province. This research was conducted in November 2017 until September  2018. All Vibrio isolates from shrimp infected WFD were identified with biochemical tests, Analytical Profile Index/ API 20NE (BioMeriuex), and PCR with specific primers for V. harveyi. Additional parameters were the water quality, plankton brackishwater pond abundance, and antibiotic resistance test. Result showed that from 17 bacterial isolates identified, 10 isolates were V. harveyi (58.82%), three isolates were V. alginolyticus (17.65%), one V. fluvialis isolate (5.88%), one V. parahaemolyticus isolate (5.88%), and two non Vibrio isolates which were identified as Shewanella putrefaciens (11.76%). All isolates of V. harveyi also showed resistance activity on more than one antibiotic. Poor water quality had been identified as abnormal result of pH, alkalinity, salinity, ammonia levels and total organic matter level. Plankton abundance observation showed that Chloropyceae, Diatom, and Dinoflagellata dominated all sampled brackishwater ponds. This research concluded that V. harveyi were discovered on vannamei shrimp with poor water quality and plankton abundance in the pond samples.

Una construcción conceptual de cara a las prácticas de enseñanza de la argumentación en la ruralidad
Authors: Guerra Meza Pedro R.
Published: July 2020

Hacer un acercamiento, con el ánimo de analizar y comprender las prácticas de enseñanza de la argumentación en la ruralidad, implica entrar en correspondencia con las concepciones de los docentes sobre lo que para ellos es práctica de enseñanza, argumentación y el concepto de ruralidad. Muchas veces se abordan los temas de la educación sin distingo de las condiciones del contexto. La ruralidad marca, indiscutiblemente, las maneras de abordar temas como la lectura, escritura y la argumentación, que son algunas de las diversas manifestaciones del lenguaje. Es por esta razón que se parte de unos interrogantes, los cuales son fundamentales para la investigación, que marcan una ruta expositiva sobre el tema en cuestión para, finalmente, develar una aproximación a las concepciones de estas tres categorías, desde las bases teóricas e investigativas, bajo los lineamientos de un horizonte sociocultural. Este, de forma segura, permite al docente apropiarse del entorno social para convertirlo en una oportunidad de aprendizajes y conocimiento constante. El contexto es variable y en esa dinámica los saberes también son cambiantes, diversos. Esto no debe ser ajeno a las prácticas de enseñanza que, entre otras cosas, su principal propósito es favorecer el desarrollo del lenguaje en todas sus manifestaciones.
Moral identity: A mediation model of moral disengagement and altruistic attitude
Authors: Yang Liheng , Cai Guoying , Yong Shaohong , Shi Haohao
Published: July 2020

We explored the relationships between college students' moral disengagement, moral identity, and altruistic attitude. Questionnaires assessing altruistic attitude, moral disengagement, moral identity, and real-life helping scenarios were used to survey 556 college students, of whom
130 were subsequently randomly selected to participate in an altruistic behavior experiment. Data were paired to verify consistency between altruistic behavior and attitude. The results show that moral disengagement was significantly negatively correlated with moral identity and altruistic
attitude. Further, moral identity was a partial mediator of the relationship between moral disengagement and altruistic behavior, but not that between altruistic behavior and altruistic attitude. Because participants with a lower moral identity and less altruistic attitude had higher moral
disengagement scores, we can conclude that the effect of diffusion of responsibility does exist.
EQUATION DECOMPOSITION METHOD FOR SOLVING OF PROBLEMS OF STATICS, VIBRATIONS AND STABILITY OF THIN-WALLED CONSTRUCTIONS
Authors: Koreneva Elena , Grosman Valery
Published: July 2020

The work suggests the effective equation decomposition method (EDM) for solving of statics, vibrations and stability problems of thin-walled constructions. This method is based on the partition of the initial problem on the consideration of more simple auxiliary problems. The additional unknown functions are introduced for definition of the sought solutions. The paper shows the method’s advantages on the examples of the boundary value problems for rectangular areas. The problem of anisotropic plate resting on an elastic subgrade and subjected to an action of expanding forces acting in the middle surface and to transverse loads is under study. The plate’s edges are elastically supported. Also free vibrations of the rectangular plates of variable thickness with different boundary conditions were under consideration. The approximate analytical solutions with high exactness are obtained.
ANALYSIS OF RHEOLOGICAL MODELS OF PROCESS OF SELF-FORMING OF GLUED WOODEN
Authors: Ponomarev Vladislav , Kashevarova Galina
Published: July 2020

The article considers a promising technology for self-shaping glued wooden elements of curved forms. This method is based on rheological processes occurring in wood, such as dehumidification and swelling of wood and its anisotropic properties.

To predict the final curved shape of the wooden structure, the authors analyzed existing rheological models of wood and concluded that the rheological model proposed by European researchers includes the most complete list of factors that affect the process of deformation of wood: elastic and plastic deformation, drying and swelling of wood, deformation of viscous-elastic creep and mechanical sorption deformation.

Based on the results of experimental studies and numerical modeling of the change in the curvature of glued wooden elements, which were made by European researchers, it was found that the proposed rheological model of wood needs to be clarified, namely, the correction of hygro-expansion coefficients depending on the moisture content of wood.

A further direction of the authors’ research will be aimed at conducting model experiments to determine the hygro-expansion coefficients of different grades of wood depending on the thickness of the wooden elements and the orientation of the layers in the glued structure.

Authors: Pratama Rheo Loridho , Sudiarto Budi
Published: July 2020

In every UPS device there are power electronic components including inverters, therefore using an inverter will cause voltage disturbances at high frequency because the switching frequency of the inverter is at high frequency. Data recorded by the oscilloscope along with the Picolog Recorder software and processed by  Matlab software to make it more efficient. Research conducted when the UPS uses dual conversion mode and with inductive load variations 0.35 H, 0.7 H, 1.4 H and 2.8 H. The test results show that voltage disturbances occur in three dominant frequency ranges at each level of load variations are 9-19 kHz, 20-30 kHz and 31-41 kHz. In the condition of 10% loading rate with a load of 0.35 H the peak voltage disturbances occur at 81.17 mV in frequency of 9.2 kHz and at the condition of the 75% loading rate with 2.8 H load the peak voltage disturbances that occur at 92.20 mV in frequency of 9.6 kHz. The disturbances voltage increases with the increasing of  inductive loads that connected to UPS.
MEMAHAMI KONSEP MAṢLAHAH IMAM AL-GAZALI DALAM PELAJARAN USUL FIKIH
Authors: Faizin Darul
Published: July 2020

Maṣlahah is an expression of taking advantage and rejecting harm, but that is not what is meant by al-Gazali; according to him, taking benefits and rejecting harm is human’s purpose, and humans good will be realized by achieving his goals. But what is meant by maṣlahah is maintaining the purpose of the Shari’a (al-muhāfaẓah ‘ala maqsūdi asy-syarī’ah). When dealing with texts (naṣ) maṣlahah is divided into three; there is a problem that is confirmed by the text (maṣlahah mu’tabarah), there is a problem that is canceled by the text (maṣlahah mulgah), and there is a problem that is unconfirmed and not canceled by the text (maṣlahah mursalah). Maṣlahah mursalah, when seen from the needs, are divided into three levels; first, the primary level (ḍarūriyāt) in the form of guarding religion (hifẓu ad-din), soul (hifẓu an-nafs), reason (hifẓu al-‘aql), descent (hifẓu an-nasl), and property (hifẓu al-māl) ), the second secondary level (hajiyāt) and the third tertiary level (tahsīniyāt). Maṣlahah mursalah can be used as a proposition for istimbāṭ by considering three characteristics, namely, maṣlahah is primary (ḍarūriyāt), certain (qath'iyyāt), and general (kulliyāt). According to al-Gazali, the purpose of the Shari’a (maqāsid asy-syarī’ah) can be known through the Qur’an, Sunnah, and consensus (ijma’). Then every maṣlahah that does not function to maintain the objectives of the Shari’a which is understood from the Qur’an, Sunnah, and the consensus (ijma') is a strange maṣlahah (gharībah), that is, a maṣlahah that is not in line with the Shari’a action, then the maṣlahah cannot be made into the proposition of legal discovery (istimbāṭ).

Komunitas Punk adalah sekelompok remaja/pemuda yang mempunyai gaya hidup yang sangat menyimpang dari norma-norma masyarakat setempat. Komunitas ini lebih dikenal dari hal fashion yang dikenakan dan tingkah laku yang mereka perlihatkan, seperti potongan rambut mohawk dan diwarnai dengan warna-warni yang terang, memakai sepatu boots, hiasan rantai, berpakaian hitam, jaket kulit, celana jeans ketat dan baju yang lusuh. Bagi kebanyakan orang, perilaku social dari kelompok punk ini dinilai negatif dan seringkali bermasalah dengan hokum maupun norma-norma sosial yang ada di masyarakat sekitar. Untuk itu Pemerintah sudah berusaha banyak dalam membendung komunitas ini. Tapi nampaknya belum ada metode yang ampuh untuk mencegahnya. Dalam hal ini penulis menawarkan metode Yang Islami dalam menangani mereka. Kata Kunci: Komunitas Punk,Motode Pembinaan, Perspektif Islam

Gempa bumi merupakan fenomena/bencana alam yang tidak dapat dihindari, mencegah terjadinya korban jiwa dalam jumlah besar merupakan sebuah tantangan bagi masyarakat dan pemerintah. Gempa yang terjadi pada 7 Desember 2016 lalu berkekuatan 6,5 skala richter mengguncang Kabupaten Pidie Jaya pada pukul 5.03.36 WIB. Pusat gempa berada di koordinat 5,25 LU dan 96,24 BT, tepatnya di darat pada jarak 18 kilometer tenggara Sigli, Pidie dan 2 kilometer Utara Meureudu, Pidie Jaya pada kedalaman 15 KM. Berdasarkan data BNPB mencatat 11.730 rumah rusak akibat gempa. Selain itu, tercatat 195 unit ruko roboh, 14 mesjid rusak, 1 rumah sakit rusak berat dan 1 unit sekolah roboh. Jumlah korban meninggal tercatat 97 orang di Pidie Jaya sebagai daerah terdampak paling parah. Selain itu, sebanyak 73 orang luka berat, 200 orang luka ringan, 10.00 ribu santri terluka. Kerugian-kerugian yang ditanggung oleh masyarakat, tidak hanya menyangkut materi, rumah, fisik, harta benda, aset-aset, pekerjaan, serta kehilangan anggota keluarga dan family, melainkan juga kerugian psikologis yang membutuhkan waktu relatif lama untuk proses pemulihannya. Peristiwa tersebut dapat menciptakan trauma tersendiri bagi masyarakat Kabupaten Pidie Jaya khususnya yang terkena dampak langsung dari musibah gempa. Adapun tujuan penelitian ini adalah untuk: (1) Mengetahui pengaruh bencana gempa terhadap trauma masyarakat; (2) Mendeskripsikan bentuk  pendekatan dan bimbingan Islami dalam pemulihan trauma bencana gempa  terhadap masyarakat; dan (3) Menganalisis peluang dan tantangan pemulihan trauma bencana gempa melalui pendekatan bimbingan Islami di Desa Teumanah Kecamatan Trienggadeng Kabupaten Pidie Jaya. Penelitian ini akan menggunakan metode deskriptif analitis dengan pendekatan kualitatif. Berdasarkan hasil yang didapatkan di lapangan bahwa masyarakat korban gempa mengalami trauma, hal ini dapat dilihat dari dua indikator, pertama: dari ciri-ciri orang yang kena taruma di mana korban gempa Pidie Jaya merasakan dalam diri mereka kewaspadaan atau reaksi berlebihan jika mendengar sesuatu bunyi sudah terkejut, gangguan tidur, di mana mereka tidak berani tidur sendirian. Kedua: dari reaksi yang muncul dari aspek emosional seperti cemas, gugup, sedih, berduka, depresi, takut, khawatir kejadian akan terulang, jika dilihat dari aspek kognitif maka reaksi yang sering muncul dalam diri mereka adalah mudah bingung dan merasa lemah seakan-akan tidak berdaya, jika dilihat dari aspek behavior reaksi yang mereka alami adalah  gangguan tidur dan gampang terkejut. Sedangkan bentuk metode bimbingan Islami yang digunakan oleh tokoh agama dari kalangan da’i perkotaan adalah Bilhikmah, mauizatul hasanah dan Mujadalah billati hiya ahsan.  Kata Kunci: Gempa, Trauma, Bimbingan

ABSTRAKArtikel ini dibuat dengan tujuan untuk menjelaskan bagaimana Peran Orang Tua terhadap Pembentukan Konsep Diri pada Anak. Metode yang digunakan adalah dengan menggunakan studi literatur atau kajian kepustakaan. Tulisan ini merupakan bentuk gagasan atau pandangan yang dihasilkan dari studi literatur atau kajian kepustakaan yang dilakukan oleh penulis dari buku-buku dan jurnal-jurnal terkait tentang Peran Orang Tua terhadap Pembentukan Konsep Diri pada Anak. Hasil yang diperoleh dari kajian yang dilakukan menjelaskan bahwa Pola Asuh Orang Tua Memiliki Peranan Penting terhadap Pembentukan Konsep Diri pada Anak. Anak yang mendapat perlakuan yang positif, seperti jika anak berbuat salah maka diarahkan, diberi pengertian dan dinasehatin sehingga anak dapat mengerti untuk memperbaiki keselahanya dengan cara yang tepat, maka akan diprediksi anak tersebut akan memiliki konsep diri yang positif juga. Konsep diri yang positif terindikasi dari kualitas penyesuaian diri yang baik, tidak ragu dalam bertindak, berani mencoba, dan berani mengambil keputusan. Pola asuh seperti ini dinamakan dengan pola asuh demokratis. Sebaliknya anak yang mendapat perlakuan yang tidak menyenangkan dari orang tuanya, seperti sering memberikan stigma negatif dengan kata-kata “nakal dan bodoh” terhadap anaknya disaat melakukan suatu kesalahan atau gagal dalam satu kompetisi, maka akan diprediksi anak tersebut akan memiliki konsep diri yang negatif. Konsep diri yang negatif terindikasi dari kualitas penyesuaian diri yang kurang baik, ragu pada diri sendiri, takut mencoba, dan tidak berani dalam mengambil satu keputusan dengan bijak. Pola asuh seperti ini merupakan bentuk dari pola asuh otoriter. Pola asuh orang tua adalah hal yang paling urgen untuk diperhatikan, diketahui dan dipahami oleh setiap orang tua, karena merupakan salah satu faktor yang paling utama yang mempengaruhi terbentuknya konsep diri pada anak. Kata Kunci : Peran Pola Asuh Orang Tua, Konsep Diri

ABSTRAKNikah siri merupakan perkawinan yang dilaksanakan sesuai dengan rukun syarat nikah menurut agama Islam tetapi tidak dicatatkan di Kantor Urusan Agama seperti yang diatur dalam Undang-undang Perkawinan Nomor 1 Tahun 1974 pasal 2 ayat 2. Perkawinan dibawah tangan akan membawa perilaku tidak baik terhadap keluarga, bermasalah hukum bagi anak yang dilahirkan, terhadap harta benda dan pasangan suami istri tersebut, karena nikah siri tidak mempunyai bukti yang autentik sehingga perkawinan tersebut tidak mempunyai kekuatan hukum, Maka munculah penelitian tentang Dampak Nikah Siri terhadap Perilaku Keluarga, Permasalahan yang dikaji adalah,  Apa itu nikah siri dan bagaimana dampak nikah siri terhadap perilaku keluarga. Hasil penelitian menunjukkan bahwa yang dimaksud dengan nikah siri adalah nikah yang dilakukan diluar Kantor Urusan Agama, artinya pernikahan ini dilakukan tidak berdasarkan hukum negara tetapi pernikahan ini dilakukan berdasarkan hukum syari’at Islam.Dampak  Nikah siri terhadap perilaku keluarga antara lain hilang tanggung jawab, sulit terjadi keharmonisan dalam keluarga, tidak saling menghormati, berbeda kasih sayang terhadap anak, .Dampak nikah siri bagi anak dan istri adalah: Anak itu tidak diakui oleh negara menurut UUD. Anak itu secara hukum dia tidak bisa mendapatkan hak waris. Tidak memiliki akte. Dampak yang lebih fatal apabila ada kasus hukum maka tidak punya kekuatan hukum yang mengikat bagi anggota keluarga karena dia tidak punya bukti autentik tentang nikah nya yang diakui oleh negara.Kata Kunci: Nikah Siri dan Perilaku Keluarga

Com a evolução da Educação a Distância nos últimos anos, muito se tem estudado sobre a importância de se considerar estilos de aprendizagem no processo de ensino a distância. No entanto, a identificação dos estilos de aprendizagem de um estudante em um ambiente EaD não é uma tarefa trivial. Este artigo busca realizar uma revisão sobre as diferentes abordagens computacionais para detecção de estilos de aprendizagem presentes na literatura. As abordagens computacionais aqui apresentadas são baseadas em técnicas da Inteligência Artificial capazes de realizar a detecção dos estilos de aprendizagem de forma automática a partir do comportamento do aluno em um ambiente virtual de aprendizagem. No total, foram selecionados 26 artigos, dos quais pode-se analisar 15 abordagens diferentes para detecção de estilos de aprendizagem. Dentre as abordagens, a mais utilizada nos trabalhos selecionados foram as Redes Bayesianas. Além disso, percebeu-se que as pesquisas relacionadas a detecção automática de estilos de aprendizagem, mesmo após as críticas recentes a teoria, continuam sendo desenvolvidas e aperfeiçoadas.

En este estudió se investigó la susceptibilidad a antibióticos y el perfil plasmídico de S aureus aislado de queso costeño, blando, semiduro y duro, expendidas en diferentes puntos de venta de la ciudad de Valledupar. Por el método de Difusión del disco en agar, se determinó la resistencia a antibióticos y con la técnica de lisis alcalina y electroforesis en gel de agarosa, el perfil plasmídico. Como resultado, se obtuvo una carga microbiana por encima de 103 UFC/g, que está sobre el valor promedio máximo permitido, según la norma covenin 1538-92, el cual indica que se puede desencadenar brotes por intoxicación con estafilocócos. Se demostró la presencia de S. aureus en los quesos costeños blandos (75%), seguidos por los quesos semiduros (25%) ambos de origen (artesanal), los cuales son de alto consumo en Valledupar. Se establecieron 4 patrones diferentes de resistencia en las cepas de S. aureus aisladas de los quesos, siendo el patrón TER común para dos cepas, el resto de los patrones fueron únicos (PR, CR y EI). Una cepa fue resistente a P, productora de β-lactamasas, su CMI más alta fue 32µg/ml; todas las cepas mostraron sensibilidad a oxacilina, gentamicina, ciprofloxacina, cefoxitin, clindamicina, trimetoprim sulfa, vancomicina, rifampin, e imipenen. Hubo bandas plasmídicas con tamaños de 23kb encontrándose cepas con 1 plásmidos.
Tumor adenomatoide de tubas uterinas, reporte de un caso y revisión de literatura
Authors: Burbano Obando Jina Paola
Published: July 2020

Los tumores adenomatoides del tracto genital son neoplasias poco frecuentes, de comportamiento benigno; debido a sus características histológicas se confunden fácilmente con tumores de estirpe vascular. Estudios recientes demuestran que los tumores adenomatoides del tracto genital femenino están genéticamente definidos por la mutación TRAF7 que activa la expresión aberrante de la vía NFkB. Presentamos el caso de una mujer de 27 años, asintomática, a quien se le realiza salpingectomía bilateral como método de anticoncepción definitivo; en el examen macroscópico de la tuba derecha se encuentra formación quística que por sus características microscópicas es diagnosticada como tumor adenomatoide de la tuba uterina. Finalmente se realiza una revisión de la literatura.
Helbredelsesforkynnelse og kristen tro

From the second half of the 19th century, some Christians have maintained that by adeptly manipulating the relevant spiritual laws, one may liberate oneself entirely from physical illness. This article is an investigation of the doctrinal context and anthropological implications of this way of understanding the Christian message. The method of the investigation is textual analyses of the writings of some of the main representatives of this movement, like Essek Kenyon and Kenneth Hagin. The context is found to be an anti-elitist kind of modernity interpreted by means of the Wesleyan understanding of Christian perfection, and the implication is a kind of ableism with a one-sided emphasis on the well-being of the strong and physically healthy. The worldview is a type of mind–matter duality, where liberation from the limits of materiality is an important goal. One rejects the idea of the spiritual value of trials and tribulations and does not seem to have a message of hope for those who struggle with chronic illness.
