Published: August 2023

Abstract
Introduction: The purpose of this study was to describe the use of Cherney Incisions as a skin incision for planned cesarean hysterectomy for placenta accreta spectrum at a single academic institution.
Methods: This was a retrospective cohort study of all patients who underwent cesarean hysterectomy for PAS through a cherney incision. Patient clinicopathological and follow-up data were extracted from medical records. This data was then compared to all other patients who underwent cherney incision via different incision. The student’s t-test was used for continuous variables and Fisher’s exact test compared categorical variables. Continuous data were compared using the Wilcoxon-rank sum test.
Results: There were 17 patients who had a planned cesarean hysterectomy for PAS at a single institution. Out of the 17 patients, 9 (52.9%) had an accreta, 6 (35.3%) had an increta and 2 (11.8%) had a percreta. The estimated blood loss was 1000cc with a range from 800cc to 3365cc. Six (33%) of patients received a transfusion, 2 (11.1%) had a complication which was found to be a bladder injury. Compared to patients undergoing cesarean hysterectomy via other incision types for PAS at our institution, there was a difference in median minutes of surgery (p = 0.041) but not from incision to delivery (p = 0.187). There was a difference in estimated blood loss, with patients undergoing chereny incision experiencing less blood loss compared to other incision types (p = 0.04) but this was not significant for receiving a transfusion (p > 0.05). All other outcomes for patients undergoing cherney incisions was similar to other patients delivered via cesarean hysterectomy for PAS.
Conclusion: This is the first study examining cherney incisions for cesarean hysterectomy for PAS. Cherney incision is not inferior to other types of skin incisions for this procedure. Future studies should include a larger cohort to further characterize the maternal, fetal and surgical outcomes of cherney incisions for cesarean hysterectomy for PAS.

Abstract

Chlorine disinfection is commonly applied to inactivate pathogenic viruses in drinking water treatment plants. However, the role of water quality in chlorine disinfection of viruses has not been investigated thoughtfully. In this study, we investigated the inactivation efficiency of coxsackievirus B5 (CVB5) by free chlorine using actual water samples collected from four full-scale drinking water treatment plants in Japan under strict turbidity management (less than 0.14 NTU) over a 12-month period. It was found that chlorine disinfection of CVB5 might not be affected by water quality. Japanese turbidity management might play an indirect role in controlling the efficiency of chlorine disinfection.
Site suitability analysis of water tank in Athivilai village of India using an analytical hierarchy process and a geographical information system

Published: August 2023

Abstract

In uneven terrain regions, the water tank location plays a significant role in pressure distribution and economical pipe sizes in the water distribution system. This study aimed to determine suitable tank locations by the analytical hierarchy process (AHP) and geographical information system (GIS). Factors such as elevation, slope, population, land use land cover, and distance to the road are considered for this analysis. Thematic maps are created in ArcGIS and weights are determined using the AHP method. From the weighted overlay analysis, the result shows that 15.59, 52.36, 31.31, and 0.63% of the areas are suitable, moderately suitable, least suitable, and unsuitable, respectively. Since the area has an elevation range of 27–87 m, it is divided into three zones. An unsuitable location falls only under one zone; therefore, the results are tested in EPANET by locating the tanks in suitable and least suitable locations. Locating the tanks in suitable locations reduces the size of pipes economically and maintains the pressure successfully while locating the tanks in the least suitable locations creates a negative pressure and increases the pipe size. This study helps the designers to obtain an effective design of a water distribution network by evaluating suitable tank locations.

Abstract

Selective electrodialysis is a promising approach to recovering K+ from complex coexisting ionic systems. In this study, the effects of current density, the concentration of K+ and Mg2+, as well as the operating temperature on the separation process of K+ and Mg2+ were explored to investigate the competitive migration of mono- and multivalent ions, offering a guide for the design of selective electrodialysis process, and therefore obtain the desired aqueous solutions containing K+ and Mg2+. The results show that ion concentration played a critical role in determining the selectivity of separation between K+ and Mg2+. High concentrations of K+ and Mg2+ led to a decrease in selectivity but the effect of concentration of K+ on selectivity was more pronounced. Although higher current density increased the flux of ions, their impact on separation selectivity was minimal. Furthermore, higher temperature increased the flux of ions but resulted in a decrease of K+ proportion in the solution. Overall, this study provides good guidance for studying the competitive migration of mono- and multivalent ions and the high-value recycling of potassium resources.

Published: August 2023

Amplitudes de ondas P, de período curto de sismos rasos registrados por estações na faixa de distância epicentral de 0° - 100°, são analisadas para a determinação dos efeitos de estação, de fonte e de distância. 56 sismos foram utilizados, 12 dos quais com epicentros no território brasileiro. As correções de estações são estimadas com limites de confiança de 95%. Os resultados mostram que o padrão das isolinhas dos efeitos de estação difere do padrão para a América do Norte. Uma curva de amplitude-distância é determinada para intervalos de 5º de distância epicentral. Essa curva indica que os efeitos de distância entre 20° e 80° não são significativos, isto é, não há desvio significativo em relação a um efeito constante nessa faixa. A curva de amplitude-distância obtida é menos irregular que a de Gutenberg-Richter. Esse resultado concorda com estudos similares de outros autores.Short Period P-Wave Amplitude-Distance Curve and Station Correction For Mb Magnitude in South America Vertical short period P-waves amplitudes from shallow earthquakes recorded by stations in the epicentral distance range 0° - 100° are analysed to determine the station, source and distance effects. 56 earthquakes were used, 12 of which having epicenters in Brazilian territory. Station corrections are estimated with 95% confidence limits. The results show that the station effect isolines pattern is different from the pattern for North America. An amplitude-distance curve is derived for 5° distance intervals. This curve indicates that distance effects between 20 and 80° are not significant, i.eThere is no significant deviation from a constant effect in this range. The amplitude-distance curve obtained here is less irregular than the Gutenberg-Richter's curve. This result is in agreement with similar studies of other authors.
Superior-Subordinate Divergence in Controllability Judgments

ABSTRACT
The controllability principle states that superiors should hold subordinates responsible only for outcomes and events that the subordinates can control. Although the principle is intuitively appealing, the extent to which this principle is applied can vary substantially in practice. Using four experiments, we predict and find evidence suggesting that the controllability judgments of superiors and subordinates can diverge even when the objective controllability of the outcome is held constant. Specifically, we find that subordinates' controllability judgments, relative to those of superiors, are consistently lower when performance outcomes are negative and sometimes higher when performance outcomes are positive. Further, we find that divergence in controllability judgments has important, negative implications for subordinates' perceptions of fairness and trust, intended effort, job satisfaction, and turnover intentions. Our results highlight several costs of implementing the controllability principle, which may help explain why the controllability principle is not universally adopted.

OBJECTIVE
Rather than during illness while diabetic ketoacidosis (DKA) is developing, we aimed to determine if levels of routine point-of-care capillary blood ketones could predict future DKA.

RESEARCH DESIGN AND METHODS
We examined previously collected data from placebo-assigned participants in an adjunct-to-insulin medication trial program that included measurement of fasted capillary blood ketone levels twice per week in a 2-month baseline period. The outcome was 6- to 12-month trial-adjudicated DKA.

RESULTS
DKA events occurred in 12 of 484 participants at a median of 105 (interquartile range 43, 199) days. Maximum ketone levels were higher in patient cases compared with in control patients (0.8 [0.6, 1.2] vs. 0.3 [0.2, 0.7] mmol/L; P = 0.002), with a nonparametric area under the receiver operating characteristic curve of 0.77 (95% CI 0.66–0.88). Ketone levels ≥0.8 mmol/L had a sensitivity of 64%, a specificity of 78%, and positive and negative likelihood ratios of 2.9 and 0.5, respectively.

CONCLUSIONS
This proof of concept that routine capillary ketone surveillance can identify individuals at high risk of future DKA implies a role for future technologies including continuous ketone monitoring.

Abstract
Drugs remain for a short time on mucus membranes, such as oral, ocular, or nasal mucus, which are washed with physiological fluids. One of the possibilities to overcome this obstacle is the application of solutions that, due to the physiological environment or stimulus, turn into more viscous gels. These gels often also have mucoadhesive properties and the drug is released from them for a longer period. Carbomer 940 (C940), polycarbophil (PCP), and chitosan (CH) are gel-forming excipients, and the consistency of their solutions changes due to the concentration of protons (pH); therefore, they are referred to as pH-sensitive gelling agents. The aim of this study was to prepare pH-sensitive solutions that form gels in the pH of the oral cavity. We prepared water solutions with various concentrations of gel-forming excipients and evaluated the appearance, pH of the solution, injectability of the solution, and pH of gelation. By determining the pH of gelation, suitable concentrations (w/w) of the used polymers were found, namely, 0.1% C940, 0.225% PCP, and 2.5% CH with medium molecular weight (CHM). The 0.1% C940 and 0.225% PCP solutions were injectable through the syringe with the smallest 0.5 mm needle diameter. The 2.5% CHM solution was not injectable even through the syringe with the largest 0.8 mm needle diameter. Solgels prepared at the determined concentrations were evaluated by a dissolution test in a pH 6.8 phosphate buffer using methylene blue (MB) as a model substance. After 60 min of dissolution, 77.04% ± 5.94%, 48.85% ± 5.74%, and 77.35% ± 4.98% of MB were released from samples with C940, PCP, and CHM, respectively. The dissolution of the C940 and CHM samples took place according to the Korsmeyer–Peppas kinetic model (R2 0.999 ± 0.001, 0.978 ± 0.003) and of the PCP samples took place according to the first-order model (R2 0.994 ± 0.001). The 0.225% PCP pH-sensitive gel showed the most advantageous properties in terms of injectability, pH gelation, and prolonged release of MB.

Published: August 2023

ABSTRAKJumlah penderita Diabetes terus meningkat setiap tahunnya, salah satu penyebab terjadinya peningkatan jumlah penderita Diabetes adalah banyaknya orang yang enggan memeriksakan kadar gula darahnya ke fasilitas-fasilitas kesehatan seperti klinik, puskesmas ataupun rumah sakit. Alasan dibalik enggannya orang-orang untuk memeriksakan kadar gula darahnya adalah karena pada metode invasif yang umum digunakan pada pemeriksaan kadar gula darah, biaya pemeriksaannya relatif mahal khususnya untuk kalangan menengah ke bawah, selain itu metode tersebut juga memberikan efek ketakutan akan jarum suntik. Untuk mendukung tindakan preventif akan meningkatnya jumlah penderita diabetes, diperlukan sebuah alat yang mampu melakukan pengujian terhadap kadar gula darah secara non invasif. Metode urine-benedict merupakan salah satu metode non invasif yang cukup akurat dalam menguji kadar gula darah. Metode ini memanfaatkan perubahan warna pada larutan benedict yang telah dicampurkan dengan urin. Dengan menggunakan sensor TCS3200, pengujian kadar gula darah secara non invasif ini bisa dilakukan dengan lebih mudah dimana sensor akan mendeteksi warna pada spesimen lalu data hasil pengujian akan diolah oleh NodeMCU ESP8266 dan kemudian dikirimkan ke perangkat IoT yang bisa dimonitor melalui aplikasi berbasis web. Sensor TCS3200 yang digunakan pada pengujian ini mampu mendeteksi spektrum warna dari spesimen yang diuji dengan baik dengan akurasi 96%. Kata kunci : Alat uji gula darah, TCS3200, ESP8266, Internet of ThingsABSTRACTThe number of people with diabetes increases every year. One of the causes of the increase in the number of diabetics is the number of people reluctant to check their blood sugar levels at health facilities such as clinics, health centers, or hospitals. The invasive method uses a needle and blood sample to measure blood sugar. People are unwilling to check their blood sugar levels because they fear the relatively expensive cost of examinations, especially for the lower middle class, and fear needles. To support the prevention of the increasing number of people with diabetes, it needs a tool that can test blood sugar levels non-invasively.The urine-benedict method is one of the non-invasive methods that is quite accurate in testing blood sugar levels. This method utilizes discoloration in the benedict solution that has been mixed with urine. By using the TCS3200 sensor, this non-invasive blood sugar level testing can be done more easily where the sensor will detect color in the specimen and then the test result data will be processed by the NodeMCU ESP8266 and then sent to an IoT device that can be monitored through a web-based application. The TCS3200 sensor used in this test is able to detect the color spectrum of the tested specimen well with an accuracy of 96%.Keywords : Blood sugar test, TCS3200, ESP8266, Internet of Things

Authors: Gunawan Muhammad Alvin , Wardhana Sukma 
Published: August 2023

VPN merupakan teknologi yang dapat membuat jaringan privat dengan memanfaatkan jaringan publik untuk mengamankan proses pertukaran data. Teknologi VPN biasanya digunakan untuk menghubungkan unit dan kantor cabang, yaitu dengan membangun terowongan antara dua lokasi. Penelitian ini memiliki tujuan utama untuk mengimplementasikan jaringan VPN antara cabang dan kantor cabang dengan penambahan jaringan keamanan untuk melindungi data agar tidak terkomunikasikan. Hal ini juga yang peneliti lakukan dalam makalah ini dengan membandingkan protokol VPN PPTP (Point-To-Point Tunneling Protocol) dan L2TP/IPsec (Layer Two Tunneling Protocol) menggunakan algoritma MPEE dan kunci enkripsi RSA RC4 128 untuk PPTP dan SHA -1 algoritma dengan AES 128 CBC, AES 128 CTR, enkripsi AES 128 GCM untuk protokol L2TP/IPsec. Setiap pengujian diberi beban lalu lintas unggah dan unduh sebesar 10MB, 20MB, dan 30MB. Hasil QoS (Quality of Service) yang meliputi throughput, packet loss, delay, dan jitter semuanya disajikan secara deskriptif dalam hasil penelitian ini. Kemudian dilakukan pengujian keamanan jaringan menggunakan Sniffing tanpa VPN, Sniffing PPTP, dan Sniffing L2TP. Pengujian keamanan jaringan menunjukkan bahwa data telah berhasil dienkripsi karena dalam pengujian keamanan ini Anda juga melihat aspek kerahasiaan apakah sudah terpenuhi atau belum. Kata Kunci: VPN; PPTP; L2TP/IPsec; Quality of Service; SecurityABSTRACTVPN is a technology that can create a private network by utilizing public network so that the data exchange process becomes secure. VPN technology is typically used to connect the unit and Branch offices, namely by constructing a tunnel between the two locations. This research has the main objective of implementing a VPN network between Branches and Branch offices with the addition of a security network to protect the data to be communicated. This is also what the researchers did in this paper by comparing the VPN protocols PPTP (Point-To-Point Tunnelling Protocol) and L2TP/IPsec (Layer Two Tunnelling Protocol) using the MPEE Algorithm and RSA RC4 encryption key 128 for PPTP and the SHA-1 Algorithm with AES 128 CBC, AES 128 CTR, AES 128 GCM encryption for L2TP/IPsec protocol. Each test is assigned upload and download traffic loads of 10MB, 20MB and 30MB. The QoS (Quality of Service) results including throughput, packet loss, delay, jitter all presented descriptively in the results of this study. Then the network security test is performed using Sniffing without VPN, PPTP Sniffing and L2TP Sniffing. The network security test shows that the data has been successfully encrypted because in this security test you also see the confidentiality aspect whether it has been met or not.
