Published: July 2022

Background:
The prognosis of middle-aged patients with colorectal cancer (CRC) treated by laparoscopic resection (LR) is unclear. This study aimed to evaluate the survival outcomes of LR compared with open resection (OR) for middle-aged patients with CRC.

Patients and Methods:
This retrospective cohort study used the data from a database of all consecutive colorectal resections performed between January 2009 and December 2017. Propensity score matching (PSM) was performed to handle the selection bias based on age, gender, body mass index, tumour location, AJCC stage and admission year. Univariate and multivariate COX regression model was used to identify risk factors of overall survival (OS) and disease-free survival (DFS).

Results:
After PSM, 154 patients were included in each group. Compared with the OR group in the total cohort, there were better survival outcomes in the LR group for 5-year OS and 5-year DFS (both P < 0.001). These differences were observed for Stage II and III diseases and for all CRC, irrespective of location. The multivariate analysis showed that tumour ≥5 cm (hazard ratio [HR] = 1.750, 95% confidence interval [CI]: 1.026–2.986, P = 0.040), Stage III (HR = 14.092, 95% CI: 1.894–104.848, P = 0.010) and LR (HR = 0.300, 95% CI: 0.160–0.560, P < 0.001) were independently associated with OS. Pre-operative carcinoembryonic antigen ≥5 ng/ml (HR = 3.954, 95% CI: 1.363–11.473, P = 0.011), Stage III (HR = 6.206, 95% CI: 1.470–26.200, P = 0.013) and LR (HR = 0.341, 95% CI: 0.178–0.653, P = 0.001) were independently associated with DFS.

Conclusions:
In middle-aged patients with CRC, LR achieves better survival than OR. Complications are similar, except for less blood loss and shorter post-surgical hospital stay with LR.
Moduli spaces on the Kuznetsov component of Fano threefolds of index 2
Authors: Altavilla Matteo , Petkovic Marin , Rota Franco 
Published: July 2022

General hyperplane sections of a Fano threefold $Y$ of index 2 and Picard rank 1 are del Pezzo surfaces, and their Picard group is related to a root system. To the corresponding roots, we associate objects in the Kuznetsov component of $Y$ and investigate their moduli spaces, using the stability condition constructed by Bayer, Lahoz, Macr\`i, and Stellari, and the Abel--Jacobi map. We identify a subvariety of the moduli space isomorphic to $Y$ itself, and as an application we prove a (refined) categorical Torelli theorem for general quartic double solids.Comment: V3: 34 pages, substantially rewritten to improve exposition, references updated.

UD. Pandawa Lima is a micro-business that produces mattresses. Product defects occur at UD. Pandawa Lima are stitching defects, mattress foam defects, and faded color defects. The purpose of this study is to use the seven tools method to find the most dominant defects and propose improvements to defects. The results showed that the most dominant defects occurred in faded color defects of 50 pcs with a percentage of 48.08%. Proposed improvements that need to be implemented are to add adequate rest hours to reduce excessive stitching defects, scheduling machine maintenance to reduce seam defects and foam size defects, choosing a reliable and good supplier to reduce faded color defects and foam size defects, and improve the production process methods to reduce color fading defects, stitch defects, foam size defects. The product defects occurred are still under controlled, it does not exceed the upper and lower control limits. There is a positive correlation, the higher production the higher level of defect in the product.

The ineffectiveness of teaching by the teacher is thought to be due to the teacher's lack of accuracy in using learning media. This is marked by the tendency of teachers to teach the material using the classical lecture method. One of the public schools that has sufficient introductory tourism value. This is because the teaching implementation system that is carried out is less effective, so that in the implementation of introductory tourism teaching that is carried out it is necessary to conduct research in order to obtain the most effective teaching to be used both on current and future opportunities online. Based on the results of the research that has been carried out, the researcher found that the students of class X Catering 1 were still low at 47.2% of the results in accordance with the KKM that had been set.

Published: July 2022

La investigación se realizó en Tamiahua, Veracruz. Con el objetivo de evaluar la erosión hídrica; Se tomaron datos sobre la pérdida de suelo cada mes. Se utilizó la técnica de clavos y rondanas en dos sitios con diferente manejo de suelo, para ello, se trazaron dos áreas con tres transectos cada uno, separados a cinco metros cada punto. Se consideró el área con diferente cubierta vegetal. Se estimó la pérdida de suelo en ambas áreas, resultando con notoria diferencia entre ellas, mostrando con ello, que, si se mantiene el suelo con cubiertas vegetales naturales o antrópicas, se evita la pérdida de suelo, que, al medirse continuamente, se incrementa esa cantidad, lo que provoca un empobrecimiento del suelo con el paso del tiempo. Se pusieron barreras de protección o contención desde inicio, con madera de tarro en forma de V, con doble propósito, el primero, para evitar la pérdida de suelo y para realizar la toma de muestra, para su análisis en el laboratorio de suelos de la Facultad de Ciencias Biológicas y Agropecuarias, donde ambas muestras resultaron con textura migajonosa (franca), con pH alcalino, también con suficiente materia orgánica. De esta forma, con la estimación de la pérdida del suelo en los sitios de los clavos y con el sedimento atrapado cerca de ellos, se demuestra que, en pendientes pronunciadas, en temporada de lluvias, existe riesgo de pérdida de suelo fértil si no se le realizan medidas preventivas de protección como barreras, incrementándose, además, si se mantiene el suelo desnudo, sin cubierta vegetal. Lo anterior, permite crear conciencia para dar un manejo adecuado a los suelos.

PurposeThere is no consensus in literature data about the influence of biological maturation (BM) on swim performance in young athletes. We analysed the relationship of BM, upper-limb power (ULP), and lower-limb power (LLP) with adolescent athletes’ performance in crawl swim.MethodsThis observational study determined the BM of 16 competitive swimmers (50% males and 50% females; 12.90 ± 0.88 years) by a mathematical model based on bone age and anthropometric measures. ULP and LLP were established by the horizontal launch test and the vertical and countermovement jump tests on a force platform, respectively. Swim performance was evaluated by the average speed in a 100-m crawl sprint.ResultsBM was related to ULP (males: <i>r</i> = 0.76, <i>p</i> = 0.001; females: <i>r</i> = 0.39, <i>p</i> = 0.02), LLP (males: vertical jump <i>r</i> = 0.80, <i>p</i> = 0.02, countermovement jump <i>r</i> = 0.48, <i>p</i> = 0.02; females: vertical jump <i>r</i> = 0.30, <i>p</i> = 0.04, countermovement jump <i>r</i> = 0.80, <i>p</i> = 0.01), and crawl swim performance (males: <i>r</i> = –0.91, <i>p</i> = 0.001; females: <i>r</i> = –0.72, <i>p</i> = 0.04). BM had a 87% contribution to crawl swim performance in males and a 66% contribution in females. ULP and LLP showed < 50% contribution to crawl swim performance in both females and males.ConclusionsBM was associated with crawl swim performance of adolescent athletes of both sexes. BM exhibited a stronger contribution to crawl swim performance than ULP and LLP in adolescent swimmers at the puberty window.

FRAUD PREVENTION AND DETECTION SYSTEM IN NIGERIA BANKING INDUSTRIES
Authors: Babando Kamalu Aliyu 
Published: July 2022

Fraud is on the rise as a result of the advent of modern technology and the global superhighways of banking transactions, resulting in billions of dollars in losses worldwide each year. Although fraud prevention technologies are the most effective method of combating fraud, fraudsters are flexible and will usually find a way around them over time. We need fraud detection approaches if we are to catch fraudsters after fraud prevention has failed. Statistics and machine learning are effective fraud detection technologies that have been used to detect money laundering, e-commerce credit card fraud, telecommunications fraud, and computer intrusion, to name a few. The program is simple to use, and anyone with permission can use it. The importance of computer technology has expanded as it has advanced in all areas of human endeavor.
