La afiliación a la seguridad social de los trabajadores y sus efectos en las finanzas de las empresas en México
Authors: Tosca Vidal Carlos Mauricio , Martínez Prats Germán , Guzman Fernandez Candelaria 
Published: September 2021

El objetivo de este artículo es determinar las consecuencias de la afiliación de los trabajadores al sistema de seguridad social con un salario inferior al real en México. Existe poca literatura acerca de la afectación de estas malas prácticas. Se realizó una investigación descriptiva tanto desde el punto de vista legal -en lo relativo a las sanciones-, como financiero -en cuanto afecta a los dueños de las organizaciones-. Tiene un enfoque cualitativo y una técnica documental. De la investigación se determinó que existen múltiples afectados: Estado, trabajadores y patrón. El Estado, porque deja de percibir el 43 % de las cuotas; el trabajador, porque al tener un accidente o incapacidades, el Estado, a través del Instituto de Seguridad Social, le reconoce sus prestaciones según el salario con el que esté inscrito; y el patrón, pues si el trabajador se accidenta, tiene la obligación de pagarle las prestaciones faltantes, para lo cual debe formar un capital constitutivo. Se concluye que los patrones deben tener en cuenta todas las consecuencias que acarrea disminuir el salario de los trabajadores al inscribirlo en la seguridad social, debido a que ponen en riesgo las finanzas de la organización y pueden llegar a ser sancionados con privación de la libertad, por dejar en estado de indefensión al trabajador.

Published: September 2021

Jalur jalan di KM 88,4 Kabupaten Maros merupakan bentang alam pegunungan yang memiliki banyak tebing terjal dengan aktivitas transportasi yang padat. Kondisi ini memungkinkan terjadinya potensi longsor. Berdasarkan hal tersebut, penulis melakukan penelitian mengenai probabilitas kelongsoran untuk mengetahui potensi terjadinya longsor pada lereng tersebut. Potensi longsor diketahui dengan menghitung nilai Faktor Keamanan (FK) dan Probabilitas Kelongsoran (PK) yang diperoleh dengan cara mengetahui geometri lereng, sifat fisik dari pengujian uji sifat fisik dan sifat mekanik dari pengujian kuat geser. Data penelitian didapatkan dengan observasi dan pengukuran langsung di lapangan dan pengujian sifat material di Laboratorium Geomekanika FTI UMI. Pengolahan data untuk mendapatkan nilai FK dan PK dilakukan dengan bantuan program komputer dengan metode perhitungan Bishop dan dilanjutkan dengan perhitungan probabilitas longsor. Dari hasil analisis yang telah dilakukan pada penelitian ini maka didapatkan nilai Faktor Keamanan (FK) sebesar 0,65 dan Probabilitas Kelongsoran (PK) sebesar 77,1%. Kedua nilai tersebut memberikan gambaran bahwa lereng pada lokasi penelitian berpotensi tidak stabil berdasarkan SRK Consulting tahun 2011 sehingga lereng tersebut membutuhkan penanganan sejak dini untuk menghindari kejadian yang tidak diinginkan. Kata-kata kunci: probabilitas longsor, faktor keamanan, lereng jalan

Abstract
A deep learning network is introduced to predict concentrations of gases in the underground coal mine enclosed region using various IoT-enabled gas sensors installed in a metallic gas chamber. The air is sucked automatically at specific intervals from the sealed-off site utilizing a solenoid valve, suction pump, and programmed microprocessor. The gas sensors monitor the gas content in the underground coal mine and communicate gas concentration to the surface server room through a wireless network and cloud storage media. The t-SNE_VAE_bi-LSTM model is proposed in this study as a prediction model that combines the t-SNE, VAE, and bi-LSTM networks. The proposed model's t-SNE method aims to minimize the dimensionality of the recorded gas concentration; the presented model's VAE layer intends to retrieve the inner characteristics of low-dimension gas concentration. Finally, the given model's Bi-LSTM layer tries to forecast the concentrations of CH4, CO2, CO, O2, and H2 gases. The proposed model's prediction accuracy is compared with the existing two models, namely auto-regressive integrated average moving (ARIMA) and chaos time series (CHAOS). The experiment findings demonstrate that the t-SNE_VAE_bi-LSTM model forecasted mean square error (MSE) is more accurate, and it has lesser MSE value of 0.029 and 0.069 for CH4; 0.037 and 0.019 for CO2; 0.092 and 0.92 for CO; 1.881 and 1.892 for O2; and 1.235 and 1.200 for H2 than the ARIMA and CHAOS models, respectively.

Abstract
Background: Many risk factors have been proposed for POP, and the cause seems most plausible to be multifactorial. This study aimed to investigate the effect of toileting behaviors on the anterior vaginal wall prolapse (AVWP) natural course.Methods: The data of 75 women who had been operated for symptomatic AVWP were recorded. The patients with grade ³II AVWP were included in this study, and they were divided into two groups according to voiding and defecation position. The volunteers who were voiding in the sitting position defined as Group 1, and Group 2 included the volunteers who were voiding in squatting position. The Colo-Rectal-Anal Impact Questionnaire (CRAIQ), Pelvic Floor Impact Questionnaire (PFIQ), Pelvic Organ Prolapse Impact Questionnaire (POPIQ), Urinary Impact Questionnaire (UIQ) and visual analog pain scores were used for evaluation of patients’ symptoms. Results: 44 patients enrolled in group 1 (sitting position) and 31 patients enrolled in group 2 (squatting position). BMI, number of parity, menopause duration, topical estrogen using, comorbidities, presence of constipation and urinary incontinence, and ped count for incontinence were similar in both groups. The time from initial symptoms to surgery was demonstrated shorter in group 2, 12 (3-73) and 24 (2-182) months, respectively (p=0.001). The PFIQ and POPIQ scores and the POP-related VAS score were statistically higher in patients who were voiding and defecating in squatting positions. Conclusion: Questioning the toileting position of patients with AVWP may be effective on the treatment option of the patient and may be beneficial on symptom control.

Abstract
Background: The duration of antiplatelet therapy after endovascular revascularization in patients with lower-extremity artery disease (LEAD) has not been well-established. This study aimed to investigate the optimal strategy for antiplatelet therapy after successful endovascular revascularization in patients with LEAD. Methods: From April 2009 to June 2019, 376 patients with LEAD underwent successful endovascular revascularization. After the procedure, the patients received mono-antiplatelet therapy (MAPT) or dual-antiplatelet therapy (DAPT) of various durations and were classified into 2 groups (MAPT or DAPT < 6 months vs. DAPT ≥ 6 months). The primary outcomes were major adverse cardiovascular events (MACE) and major adverse limb events (MALE). The safety outcome was moderate-to-severe bleeding according to the Global Use of Strategies to Open Occluded Arteries (GUSTO) criteria.Results: Over the 40-month follow-up period, MACE occurred less frequently in the DAPT ≥ 6 months group than the MAPT or DAPT < 6 months group (12.4% vs. 23.8%; hazard ratio: 0.62; 95% confidence interval: 0.40 to 0.97; p = 0.038) after inverse probability-weighted adjustment and propensity-score matching. The incidence of MALE showed no significant intergroup difference (17.1% vs. 13.1%; hazard ratio: 0.94; 95% confidence interval: 0.56 to 1.59; p = 0.822). The incidence of moderate-to-severe GUSTO bleeding also showed no significant intergroup difference (3.5% vs. 4.9%; hazard ratio: 0.59; 95% confidence interval: 0.21 to 1.63; p = 0.308). Conclusions: For patients with LEAD, DAPT for ≥6 months after endovascular revascularization was associated with a lower incidence of MACE without increasing the risk of bleeding events.

Abstract
PurposeMany studies have shown that multiparametric magnetic resonance imaging (MRI) may be helpful for differentiating malignant renal cell carcinomas (RCCs) from benign lesions. However, the key image characteristics between malignancy and benign tumors still require further discussion. MethodsWe gathered 60 adult patients diagnosed with 72 small renal masses (SRMs) who had received preoperative MRI from 2014 to 2019 at a hospital in Taiwan. The MRI features included conventional MRI parameter, diffusion weighted image (DWI), and dynamic contrast enhanced (DCE) pattern, which are documented and compared among the four common subtype groups: clear cell RCC(ccRCC), papillary RCC(pRCC), angiomyolipoma(AML) and other type RCC. An apparent diffusion coefficient (ADC) value of high and low grade RCCs was also analyzed. ResultsThe results show that ccRCC had higher T2 weighted signal intensity than the other three subgroups, higher arterial wash-in index (AWI) and ADC value than AML and pRCC, and also manifested a plateau (n=9, 25%) or washout (n=27, 75%) dynamic pattern. AMLs exhibited more intravoxel fat than the other three subtypes groups and half of AMLs (6 in 12) contained bulk fat. The pRCC demonstrated a more progressive (n=3, 60%) dynamic pattern than other three subgroups. The ADC value of high-grade RCCs was significantly lower than the low-grade RCCs.ConclusionThis may indicate that multiparametric MRI is useful in differentiating those four common pathological types of SRMs and the ADC value may be helpful in evaluation of the histological grade of malignancy.

Published: September 2021

Abstract
Why puddling? It is an important operation to minimize soil nutrient leaching and thereby increasing the availability of plant nutrients and achieving reduced soil condition. Good puddle field conditions are needed to create favorable environment for normal growth of rice plants. However, long-term effects of puddling could lead to forms of large clods in fine textured soils; resulting in negative effect on the soil characteristics, preventing seed-soil contacts and leading to decline in rice yield. This study was conducted in 2 years with treatment including; puddling the land twice with moldboard plow and pre-germinated seeds were hill-seeded with direct seeding machine (PD), puddling the land twice with rotary tiller and pre-germinated seeds were hill-seeded with direct seeding machine (RD), puddling the land twice with moldboard plow and 15-day-old seedlings were hill-transplanted with transplant machine (PT), and puddling the land twice with rotary tiller and 15-day-old seedlings were hill-transplanted with transplant machine (RT) to assess the effect of puddling, direct seeding, and mechanical transplanting on soil characteristics and rice yield. Results revealed significant improvement in the bulk density and increase in SOC, N, P and K in PD. The maximum microbial population was found in PD. Rice yield showed a higher productivity increase of 7.44 t∙ha-2 and 3.91 t∙ha-2 in 2017, and 7.85 t∙ha-2 and 3.94 t∙ha-2 in 2018 respectively for 1H and 2H (1H: 1st harvest, and 2H: 2nd harvest) in PD. Overall, PD was found to be the most suitable puddling and rice establishment approach under paddy fields for soil improvement and increasing rice yield.

Abstract
This study was aimed to analyse the effect of a fermented feed additive on the broilers' histology/morphology of the GIT, immune status, and microbiota as an alternative to AGP. Four groups of 288-day-old male and female Arbor Acre broilers were randomly divided (6 replicates in each group each with 12 chicken). Negative control (NC; basal diet), positive control (PC; basal diet +antibiotic virginiamycin 15ppm) one of the 2 fermented feed additives (FFA) diets prepared by adding, fermented feed additive low dose (FFL; basal diet + 0.3kg/t Lactobacillus casei fermented feed additive) and fermented feed additive high dose (FFH; 3kg/t Lactobacillus casei fermented feed additive). Composition of fermented feed: total bacteria count: 2×109CFU/g，Lactic acid 20mg/g, acetic acid 5mg/g, succinic acid 7mg/g, pyruvic acid 0.1mg/g. The research demonstrated that including fermented feed additives (FFA) in the diet provided overall benefits, FFL and PC diets showed improved (1-21 day) feed conversion ratio (FCR) compared to NC from 0-42 day (P < 0.05). FFH and FFL showed improve intestinal morphology within the duodenum, jejunum, and ileum with higher villus height (VH), and villus height to crypt ratio (VH/CR) (P < 0.05). Duodenum and ilium crypt depth was highest in PC and FFL respectively (P < 0.05). FFH had a significantly lower thymus weight compared to NC (P < 0.05). Furthermore, fermented feeds FFL and FFH influenced the intestinal immunity-related mRNA levels and increased expression of IL-10 (P < 0.05). FFL down-regulated the mRNA expressions of IL-1β and TLR4 (P < 0.05). Both fermented feeds FFL and FFH positively modulated the composition and variety of cecal microbiota compared to the NC.

Published: September 2021

Abstract
BackgroundCurcumae Radix is a multi-source Chinese medicine called Yujin. It is derived from the root tubers of four Curcuma species including Curcuma wenyujin , C. kwangsiensis , C. phaeocaulis and C. longa. The identification of the root tubers of the four Curcuma species often caused confusions. MethodsIn this study, we developed HPLC/PDA methods to differentiate these four species of Curcumae Radix by HPLC assay and fingerprint analysis. The methods developed were also validated with their precision, repeatability and accuracy. ResultsCurdione could only be detected in C. wenyujin . For C. kwangsiensis , C. phaeocaulis , if the relative peak area value of peak 1 and germacrone peak of the samples was more than 1.024, it could be identified as C. phaeocaulis of Curcumae Radix. Curcumin, desmethoxycurcumin and bisdesmethoxycurcumin could only be detected in C. longa . We also developed a simple method to determine curcumin, desmethoxycurcumin and bisdesmethoxycurcumin in C. lon ga and germacrone in the other three species of Curcumae Radix. ConclusionsBecause of the definite difference of main ingredients between curcumin-free group (C. wenyujin , C. kwangsiensis and C. phaeocaulis ) and curcumin containing C. longa from this study, four Curcuma species of Curcumae Radix in the pharmacopeia should be separated into two monographs, with curcumin-free and germacrone containing species as one and curcumin containing C. longa as the second monograph. The HPLC/PDA methods of HPLC assay and fingerprint analysis developed in this study could be used for the quality control of these four species of Curcumae Radix.

Published: September 2021

Abstract
Macrophomina phaseolina, a necrotrophic fungal pathogen is known to cause charcoal rot disease in food crops, pulse crops, oil crops and cotton and fibre crops. Necrotrophic fungi survive on dead plant tissue. It is well known that reactive oxygen species (ROS) are produced by host plant during plant pathogen interaction. However, it is still unclear how M. phaseolina can overcome the ROS induced cellular damage. To mimic the invasion of M. phaseolina inside the plant cell wall, we developed solid substrate fermentation where M. phaseolina spore suspension was inoculated on wheat bran bed and incubated for vegetative growth. To analyse the secretome of M. phaseolina after different day interval, its secretory material was collected and concentrated. Both superoxide dismutase (SOD) and catalase were detected in the secretome by zymogram. The presence of SOD and catalase was further confirmed by liquid chromatography based mass spectrometry. The physicochemical properties of M. phaseolina catalase in terms of stability towards pH, temperature, metal ions and chaotropic agent and inhibitors indicated its fitness at different environmental conditions. Apart from the production of catalase in SSF, the studies on this particular microorganism may also have significance in necrotrophic fungal pathogen and their susceptible host plant interaction.

Abstract
BackgroundIdentifying neural markers of autism spectrum disorder (ASD) before behavioral symptoms emerge can improve outcomes through early treatment. This study aimed to characterize the neural correlates of face processing in 12-month-old infants at familial risk of developing ASD by (1) comparing face-sensitive event-related potentials (ERP) (Nc, N290, P400) between high-familial-risk infants who develop ASD (HR-ASD), high-familial-risk infants without ASD (HR-NoASD), and low-familial-risk infants (LR), and (2) evaluating how face-sensitive ERP components are associated with language, communication and social development.Methods 12-month-old infants participated in a study in which they were presented with alternating images of their mother’s face and the face of a stranger (LR = 45, HR-NoASD = 41, HR-ASD = 24) as EEG data were collected. Parent-reported and laboratory-observed language and social communication measures were obtained at 12 months, and laboratory-observed social skills measures were conducted at 18 months. Group differences in ERP responses were evaluated using ANOVA, and multiple linear regressions were conducted with maternal education and outcome groups as covariates to assess relationships between ERP and behavioral measures. ResultsFor each of the ERP components (Nc, N290, and P400), the amplitude difference between mother and stranger (Mother-Stranger) trials was not statistically different between the three outcome groups (Nc p = 0.72, N290 p = 0.88, P400 p = 0.91). Marginal effects analyses found that within the LR group, a greater Nc Mother-Stranger response was associated with better expressive language skills on the MSEL, controlling for maternal education and outcome group effects (slope 1.15; p < 0.01). No significant associations were observed between the Nc and language or social measures in HR-NoASD or HR-ASD groups. In contrast, specific to the HR-ASD group, amplitude difference between the Mother versus Stranger P400 response was positively associated with expressive (slope 2.1, p<0.001) and receptive language skills at 12-months (slope 1.68, p < 0.005), and better social skills (slope 0.66, p < 0.005) at 18-months. ConclusionsIn 12-month-old infant siblings with subsequent ASD, increased P400 response to Mother over Stranger faces is positively associated with concurrent language and future social skills.
