A joint business group is a group of citizens or a group of social communities formed from families classified as poor communities through a social welfare program, abbreviated as prokesos, which is useful for carrying out business to increase the income of a group of underprivileged residents. In the decision-making process, errors and inaccuracies in the distribution of aid to the community, for example, people who do not deserve assistance but who receive assistance are inversely proportional to poor communities who do not receive assistance. This problem arises because of the lack of careful selection and miscalculation in determining which people are entitled to receive assistance. For this reason, it is necessary to have a decision support system in producing decisions so that it can support the decisions made by the Province of Social Affairs more real. In this study, one of the Composite Performance Index (CPI) methods is used which is expected to be able to assist the Provincial Social Service in determining the appropriate kube in receiving assistance.

Published: August 2021

In the process of printing images, a high-quality plotter printer is required to obtain better printed images. This causes the costs incurred to purchase a plotter printer become even higher along with the quality of the printout. In addition, the use of original plotter printer ink is significantly more expensive than that of the non-original ink. Therefore, this paper proposes a pen based computer plotter printer design using the CoreXY framework. This framework is based on a 2D in-axis motion control technique using a single continuous belt for both axes. To evaluate the performance of the proposed design, the level precision for vector and raster modes are measured using the Mean Absolute Percentage (MAPE). Based on the results of precision measurements, it was found that the printer prototype designed to produce high-precision images with affordable pen ink costs and can process digital instructions from a computer using Computer Numerical Control (CNC).

COVID-19 is a pandemic that is troubling many people. This has led to a lot of public comments on Twitter social media. The comments are used for sentiment analysis so that we know the polarity of the sentiment that appears, whether it is positive, negative, or neutral. The problem when using twitter data is that the tweet data still contains many non-standard words such as abbreviated writing due to the maximum limitation of characters that can be used in one tweet. Preprocessing is the most important initial stage in sentiment analysis when using Twitter data, because it affects the classification performance results. This study specifically discusses the preproceesing technique by performing several test scenarios for the combination of preprocessing techniques to determine which preprocessing technique produces the most optimal accuracy and its effect on sentiment analysis. Feature extraction using N-Gram and word weighting using TF-IDF. Mutual Information as a feature selection method. The classification method used is SVM because it is able to classify high-dimensional data according to the data used in this study, namely text data. The results of this study indicate that the best performance is obtained by using a combination of cleaning and stemming; and normalization of words, cleaning, and stemming with the same accuracy of 77.77%. the use of unigram results in higher accuracy compared to bigram. Mutual Information is able to reduce overfitting problems by reducing irrelevant features so that train and test accuracy is quite stable

The process of deteriorating television should indeed be done by an expert who is a television expert himself, but because television is a tool that is no longer common for people to know him, many people also have television in their respective homes. Even for television repairs, it is quite expensive, so some people who have televisions can do television maintenance at home. The lack of knowledge possessed by the community can lead to wrong handling of television maintenance / maintenance and this has a fatal impact. Hopefully the existence of this system can help the community in diagnosing the damage to their televisions. In that case they need not bother to call for repairmen or bring in a television repair shop. Here the authors provide solutions to solve the problems that often arise on television. In this study, it discusses how to care for television officers. The research objective is to analyze a desktop-based expert system program that contains the knowledge of an expert / doctor whose truth is believed to have the ability to be able to diagnose the disease from the symptoms of damage that has been damaged by television damage quickly and precisely. The stages of research carried out in this study include literature study, data collection, system design, system creation, system testing. Case Based Reasoning is a method used to build a knowledge-based system. The source of system knowledge is obtained by collecting the handling of cases by an expert / expert. Therefore, many problems in television damage are usually due to the negligence of the television owner himself. The first step in solving a problem is by first identifying the scope of the problem to be resolved, this also applies to any Artificial Intelligence (AI) programming.

Persistencia de efectos a largo plazo de la fertilización fosfatada y la introducción de leguminosas en pastizales del Uruguay
Authors: Del Pino Machado Amabelia , Lezama F. , Pezzani F. , Parodi G.
Published: August 2021

En el campo natural (CN) de Uruguay la introducción de leguminosas con fertilización fosfatada (CN+LP) evita restricciones nutricionales, pero son poco conocidos sus efectos sobre el suelo y la pastura. Para evaluar estos efectos en el largo plazo se utilizó un experimento previo de introducción de Lotus corniculatus y fertilización fosfatada con un tratamiento testigo de CN (1995-2002). Entre 2013 y 2015 se determinó la producción primaria neta aérea (PPNA), contenido de nutrientes de la planta, composición y diversidad florística. En el suelo se analizó pH, contenido de C orgánico, P disponible y orgánico. En dos gramíneas nativas se  evaluó la colonización micorrícica. El suelo CN+LP presentó mayor contenido de P disponible, pero no hubo diferencias en C orgánico. Aunque la PPNA fue similar, el contenido de P del forraje fue mayor en CN+LP respecto a CN, mientras que la micorrización fue mayor en CN. La composición florística y la diversidad no difirieron. Se concluye que, aunque no se mantuvieron las ventajas productivas de CN+LP en PPNA, hubo una mejora en la calidad del forraje debido a su mayor contenido de P. Sin embargo, no hubo efectos en servicios ecosistémicos claves  como la diversidad de especies.

El empleo de variedades de maíz de libre polinización adaptadas a ambientes específicos representa una alternativa para productores de zonas marginales para los cuales es problemática la adopción de cultivares híbridos de última generación por su alto costo. A pesar del mayor potencial de rendimiento de los cultivares híbridos, las variedades de polinización libre pueden ser ventajosas por su adaptación, estabilidad, menor costo y la posibilidad de obtener semilla propia. Dos poblaciones de maíz de libre polinización fueron desarrolladas mediante métodos de selección recurrente para adaptación a la zona semiárida del centro de la provincia de Córdoba. Las variedades obtenidas se compararon con cultivares híbridos comerciales durante tres años en experimentos a campo y presentaron buenas características agronómicas relativas a los componentes del rendimiento, resistencia a enfermedades prevalentes, calidad y rendimiento en grano.

Dynamic processes in an active region in the initial and impulsive phases of the eruptive flare event on June 7, 2011
Authors: Babin Artur , Koval' Aleksandra
Published: August 2021

We present the results of an analysis of Hα monochromatic and spectral observations obtained at the Crimean Astrophysical Observatory for an impressive filament eruption during a flare occurred on June 7, 2011. Our ground-based observations are combined with data acquired by multiple instruments onboard the Solar Dynamics Observatory (SDO/AIA, SDO/HMI). The evolution and dynamics of the eruptive process, the cause of eruption, the structure of the line-of-sight velocity field and fine internal structure of the eruptive filament are studied and a number of physical parameters of the eruptive filament are determined.

The results of the analysis have shown that: 1) The evolution of the filament eruption consists of two phases: the slow-rise phase, which began about two hours before the flare onset, and the fast-rise phase, which began almost simultaneously with the flare onset. 2) The eruptive filament had a very complex internal structure and complicated line-of-sight velocity field. The filament does not erupt as a single structure. Several discrete massive absorption fragments are seen with a large number of fine-structure elements inside fragments with different velocities, as well as many plasma blobs that detach from the fragments. 3) The motion of the filament fragments is a combination of rotational motion around the axis of the fragment and a movement as a whole towards the observer. The velocities of such plasma motions are determined. 4) Hα line profiles show a large variety of contrast values, Doppler half-widths and Doppler shifts in eruptive filament elements.

Published: August 2021

Objective: The mode of giving birth has changed over the years. In 1990, approximately 10% of women delivered by Cesarean section (CS), whereas this procedure is performed daily in obstetrics today. When a surgical intervention performed, it is necessary to consider special risks and complications, including long-term effects. Mechanism: This review focuses on fertility after CS. Evidence suggests that many women who aim to have subsequent children have difficulties becoming pregnant after they have delivered by CS. Findings: There are several causes for subfertility/infertility after CS, including post-Cesarean niches, intraabdominal adhesions, and the preference for a smaller family size, among others. Conclusion: This review provides an overview of the available literature, which supports the conclusion that CS is associated with decreased odds of subsequent pregnancy and live birth.

Objective: The aim of the study was to present selected oncological problems among girls and young women. Mechanism: Malignant ovarian cancers grow faster in girls. Due to the lack of an anatomic barrier, they spread rapidly from the pelvis to the organs in the entire peritoneal cavity. High-grade cancers may be associated with an insufficient immune response that controls the early tumour growth. Findings and brief: Paediatric cancers represent about 1% of all diseases; fortunately, in developmental age gynaecology this is not a frequent problem, yet its significance requires intense specialist actions. Although they most often occur in adult women, malignant lesions may also affect girls (e.g., cervical germ cell tumour). Therefore, the importance of early detection of neoplastic ovarian lesions at any age is emphasised. Cervical cancer is also an oncological issue in developmental age gynaecology (the immature metaplastic epithelium is particularly sensitive to the oncogenic effects of HPV (Human Papillomavirus)), hence any prophylaxis, especially vaccinations, are of great importance in this respect). Apart from typical genital cancers, there can also be cancers where the genitourinary system is just one of the possible locations. Conclusions: Fortunately, cancers are not frequent in developmental age gynaecology, yet the significance of this problem requires intense specialist actions.

Background: There are increasing concerns towards the transmission of extended spectrum-β-lactamases (ESBL)-producing Enterobacteriaceae in hospital intensive care units (ICUs) at obstetrics & gynaecology departments. The aim of this study was to determine the clinical characteristics and prevalence of ESBL-producing Escherichia coli (E. coli) and Enterobacter cloacae (E. cloacae) isolates collected from ICUs at obstetrics & gynaecology departments in a tertiary care hospital, China. This study also explored the treatment options for E. coli and E. cloacae infections. Methods: E. coli and E. cloacae isolates from ICU samples were identified by using the Vitek 2 Compact System with the GN and ASTGN13 cards. Antimicrobial susceptibility profiles were determined by using the broth microdilution method. Double-disk synergy test (DDST) was performed to screen for ESBLs and combined with the EDTA-disc synergy to detect the production of carbapenemase. Enterobacterial repetitive intergenic consensus (ERIC)-PCR was applied to investigate the clonality of the isolates. Results: A total of 223 strains isolated from 283 hospitalized patients in the ICU with nosocomial infections between 2017 and 2019 were analyzed. Of these, 104 isolates were classified as E. coli and 103 isolates as E. cloacae by the VITEK GNI system. Of the 207 isolates, 131 (63.3%) were separated from sputum or tracheal secretions. ESBL-screen positive was 45.2% (47/104) for E. coli, and 44.7% (46/103) for E. cloacae. Resistance rates of ESBL-producing E. coli and E. cloacae isolates were 95.5% and 91.3% for ampicillin, respectively; 80.6% and 76.1% for ampicillin/tazobactam; 88.1% and 28.3% for ciprofloxacin; 89.6% and 15.2% for levofloxacin; 34.3% and 45.7% for netilmicin; 82.1% and 41.3% for compound sulfamethoxazole; 20.9% and 43.5% for amikacin; 58.2% and 37.0% for gentamicin; 20.9% and 69.6% for piperacillin/tazobactam. Additionally, all ESBL-producing isolates were fully resistant to cefazolin, cefuroxime, ceftazidime, ceftriaxone, cefepime, and aztreonam. On the other hand, isolates were fully susceptible to imipenem and meropenem. Results of ERIC-PCR in all of ESBL-producing E. coli isolates exhibited 11 distinct patterns with a similarity coefficient of 0.8. Only one distinct ERIC pattern was observed amongst the 46 strains of ESBL-producing E. cloacae. Analysis of ERIC patterns demonstrated that there was an outbreak of nosocomial infection of ESBL-producing E. coli and E. cloacae in obstetrics & gynecology ICU of this hospital. Discussion: Our data indicate that the ESBL-producing E. coli and E. cloacae are circulating in the ICU and constitute a major source infection spread. It is necessary to increase surveillance of infections in the ICU and develop adequate infection prevention strategies.

Background: Chronic pelvic pain (CPP) has a significant impact on patients’ health-related quality of life (HRQoL). Endometriosis is a common cause of CPP. Data is lacking on long-term HRQoL outcomes in patients with endometriosis-associated chronic pelvic pain (EACPP) versus other causes of chronic pelvic pain (OCPP). Methods: In this retrospective single-survey study, 198 patients completed the EHP-30 and the patient-reported outcomes measurement information system (PROMIS) Global Health validated questionnaires to assess health-related quality of life (HRQoL) 8–10 years after index surgery. Results: Demographic comparison revealed significant differences in racial demographics and disability status between the EACPP and OCPP groups. There was no significant difference in EHP-30, PROMIS Global Physical, or Global Mental scores between the two groups. Patients with lower stage endometriosis (stage I/II) reported diminished HRQoL in the EHP-30 and Global Physical scores as compared to patients with higher stage (stage III/IV) endometriosis or OCPP. Additionally, no differences were found between incidence of abuse history and EHP-30 and PROMIS scores between the two groups. Higher age and higher PROMIS Global Physical scores were associated with lower pain and higher HRQoL scores on the EHP-30. Persistently high rates of sexual dysfunction were seen across both groups. Discussion: This study demonstrates that women with EACPP and OCPP appear to have similar natural histories and quality of life on long term follow-up. Race, age, disability, and physical health status may play key roles in perceived quality of life. The high rate of persistent sexual dysfunction is concerning and requires increased clinician intervention.

Background: To determine the association between increased nuchal translucency (INT) and fetal outcomes among Thai population. Methods: A prospective database of fetal Down syndrome screening project was accessed to enable retrieval of the records of any women with recorded NT measurements. The selected pregnancies were categorized into the INT group (>95th percentile) and the normal (<95th percentile) group. The effectiveness of NT for prediction of Down syndrome and hemoglobin Bart’s disease was also determined. Pregnancy outcomes were compared, also using multivariate analysis to correct the major confounders. Results: Out of 8225 NT measurements recorded, data from 7126 fetuses were available for analysis. These included 357 in the INT group and 6769 in the normal group. INT was significantly associated with Turner syndrome, Down syndrome, Edwards’ syndrome, Patau syndrome, cardiac defect and Hb Bart’s disease. After exclusion of fetal abnormalities, rates of abortion, low birth weight (LBW), preterm birth and intrauterine death (IUD) were significantly higher in the INT group, with adjusted odds ratio (95% CI) of 7.82 (7.48–13.66), 0.60 (0.42–0.86) and 5.10 (1.11–23.42), respectively. INT was effective in predicting Down syndrome with a sensitivity of 61.1% with a false positive rate of 5%. Conclusions: In addition to effectiveness in screening aneuploidy and cardiac defect, INT significantly increased the identification of risk of some diseases specific to a certain geographical area, for example Hb Bart’s disease in Thailand. Among the euploid fetuses in this study the rate of abortion, LBW, preterm birth and IUD were also significantly increased.

Background: The purpose of this study was to investigate whether the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) can be used as supplemental tools to differentiate between uterine myomas and sarcomas. Methods: From January 2000 to May 2020, patients diagnosed with uterine sarcoma or myoma after surgery at the Catholic University Hospital of Daegu were enrolled in the study. The age and preoperative hematologic findings including hemoglobin, white blood cell count, neutrophils, lymphocytes, platelet counts and lactate dehydrogenase were retrospectively investigated. Results: A total of 366 patients, including 40 uterine sarcoma patients and 326 uterine myoma patients, were included in the study. Among the hematologic findings, NLR and PLR showed statistically significant differences between uterine sarcoma and myoma. The probability of sarcoma was high when NLR was ≥2.6 and PLR was ≥150.0. When NLR was ≥2.6, the odds ratio of uterine sarcoma risk was 9.761 (95% confidence interval [CI]: 3.950–24.120, P < 0.001). When PLR was ≥150, the odds ratio of uterine sarcoma risk was 3.502 (95% CI: 1.528–8.027, P = 0.003). If NLR was above their cut-offs, the sensitivity of uterine sarcoma diagnosis was 60% and specificity was 83.4%. Identically, PLR was 60% and 73.3%, respectively. Conclusion: NLR and PLR are useful supplemental tools for the differential diagnosis of uterine myoma and sarcoma. Therefore, more expensive and accurate imaging studies, such as magnetic resonance imaging, can be more effectively recommended when these hematologic findings are used together with pelvic ultrasonography.
