Authors: Wu Mengxi
Published: November 2021

Coronavirus disease, or simply COVID-19, has affected many regions worldwide. The pandemic has caused great losses from all walks of life. Millions of people have died from the virus. In order to facilitate people’s understanding of COVID-19, the present study adopts the theory of semantic field to analyze the COVID-19 lexicon that appeared in China Daily, an authoritative international daily newspaper issued by China. A total of 100 pieces of English news issued by China Daily have been randomly selected for this research. According to the theory of semantic field in structural linguistics, the meaning of a word cannot stand alone, but come into being with the meanings of its related words. Therefore, it is reasonable to try to understand COVID-19 as thoroughly as possible with relevant words, which form its semantic field.

Published: November 2021

Objective: This study analyzed the risk factors of neurological complications in patients with Stanford type A aortic dissection after Sun’s procedure in a single-center with the purpose of improving the effects. Methods: From January 2019 to December 2020, the clinical data of 480 patients with Stanford type A aortic dissection, who were treated by Sun’s procedure in our center were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the risk factors of postoperative neurological complications. According to whether there were neurological complications after surgery, they were divided into two groups: the group with complications (n=70) and the group without complications (n=410). The clinical data of the two groups were collected and compared. Results: There were 70 cases of patients with postoperative neurological complications in 480 cases. The incidence rates of temporary neurological dysfunction (TND) and permanent neurological dysfunction (PND) was 11.5% (55/480) and 3.1% (15/480), respectively. Univariate analysis showed that the age (? 70 years), stroke history, femoral artery intubation and cardiopulmonary bypass (CPB) time were associated with postoperative PND (p < 0.05). Renal dysfunction, emergency surgery, postoperative hypernatremia, postoperative hyperglycemia, postoperative hypoxemia, postoperative low cardiac output syndrome, and assisted time of suction influenced the occurrence of postoperative TND (p < 0.05). Multivariate logistic regression analysis showed that age (? 70 years), stroke history, femoral artery intubation and CPB time were independent risk factors for PND. Renal dysfunction, emergency surgery, postoperative hypernatremia, postoperative hyperglycemia, postoperative hypoxemia, postoperative low cardiac output syndrome, and aspiration time were independent risk factors for TND. Compared with the two groups, the hospitalization time and ICU time of the patients in the neurological complications group were significantly prolonged, and the mortality rate was significantly increased (p < 0.05). Conclusion: There are many risk factors for neurological complications in patients with Stanford type A aortic dissection after surgery. With the improvement of surgical techniques, optimization of cerebral perfusion, and interventions for risk factors, Sun’s procedure remains the preferred treatment for Stanford type A aortic dissection.

Authors: Yu Nannan , Li Renting
Published: November 2021

Radiotherapy is a common treatment for abdominal and pelvic malignancies with bone metastases. However, some patients develop radiation enteritis (RE) during the treatment or 2 months or more after the treatment, which seriously affects their quality of life. At present, the curative effect of western medicine is poor. Professor Renting Li believes that radiation kills tumor cells but at the same time, it damages the healthy Qi of the human body. Radiation causes heat and poison to accumulate in the intestinal tract, consumes and hurts Yin fluid, burns the vein, leads to deficiency of healthy Qi and poor detoxification, as well as cause blood stasis after a period of time. All these result in the combination of heat, blood stasis, and poison, manifesting as abdominal pain, diarrhea, mucus in stools, purulent and bloody stools, etc. Therefore, Professor Renting Li proposed the use of traditional Chinese medicine retention enema combined with oral traditional Chinese medicine to reduce symptoms, remove toxins, and improve the quality of life of patients.

Keyword research is one of the essential activities in Search Engine Optimization (SEO). One of the techniques in doing keyword research is to find out how many articles titles on a website indexed by the Google search engine contain a particular keyword or so-called "allintitle". Moreover, search engines are also able to provide keywords suggestion. Getting keywords suggestions and allintitle will not be effective, efficient, and economical if done manually for relatively extensive keyword research. It will take a long time to decide whether a keyword is needed to be optimized. Based on these problems, this study aimed to analyze the implementation of the web scraping technique to get relevant keyword suggestions from the Google search engine and the number of "allintitle" that are owned automatically. The data used as an experiment in this test consists of ten keywords, which each keyword would generate a maximum of ten keywords suggestion. Therefore, from ten keywords, it will produce at most 100 keywords suggestions and the number of allintitles. Based on the evaluation result, we got an accuracy of 100%. It indicated that the technique could be applied to get keywords suggestions and allintitle from Google search engines with outstanding accuracy values.

Published: November 2021

This study reported the reduction of metal Hg(II) from water using natural kaolinite (NK) based adsorbents compared with modified kaolinite adsorbents with Hexadecyl trimethyl ammonium bromide anionic surfactants using ultrasonic technology (SMK). These adsorbent samples were characterized using several different techniques such as FTIR, X-RD and AAS analysis. The adsorption capacity is influenced by variables such as the contact time and adsorben dosage. The results of the analysis reported that the maximum waste reduction efficiency occurs in modified kaolin (SMK), where adsorption occurs faster than natural kaolin (NK). The maximum persentation is 94.57% for metal removal efficiency using modified kaolin at the contact time of 45 minutes and the dose of adsobene 1.4 g, while kaolin without modification is 73.83% of efficiency at the contact time of 60 minutes the adsobent dose was 1.4 g. The use of the adsorption method with the help of ultrasonic technology is proven to be more efficient in accelerating the removal of Hg2+ ions by increasing the surface dispersion of the adsorbent with metal ions in water. The adsorption kinetics model that is suitable for calculating the adsorption capacity of the adsorbent in the removal of Hg2+ ions using unmodified kaolin is pseudo-second-order models.

Published: November 2021

Biodegradable polymers are seen as a potential solution for the environment generated by plastic waste. The purpose of this study was to see the effect of adding a catalyst to the manufacture of PLA/PCL-Catechin-Chitosan as a raw material for making plastics . This research was carried out with variations in the addition of ZnO catalyst 0.1 % (PPXya), 0.2% (PPXyb) and 0.3% (PPXyc ). From the results of the analysis using Fourier Transform Infrared (FTIR) obtained stretching groups of  OH, CO and C= O at wavelengths (3860, 1060 and 1753) cm-1 at the addition of 0.3% ZnO catalyst (PPXyc ). Based on the analysis of the thermal stability using Thermogravimetry (TGA) the decomposition temperature was obtained at 387℃ with the addition of catalyst 0.3% (PPXyc ).

Manggis mempunyai prospek tinggi dalam skala agribisnis. Berdasarkan data ekspor komoditas pertanian sub sektor hortikultura (buah-buahan segar), manggis berada pada peringkat ke-1 pada tahun 2020. Kendala budidaya manggis adalah rendahnya kualitas buah yang tidak layak ekspor yang disebabkan oleh serangan hama dan penyakit. Umumnya, upaya para petani manggis saat menghadapi masalah tersebut adalah berkonsultasi dengan seorang pakar. Namun, ketersediaan dan kehadiran pakar dalam suatu daerah masih sangat terbatas. Sistem pakar menjadi solusi untuk mengidentifikasi hama dan penyakit pada tanaman manggis secara cepat. Sistem pakar dihadirkan sebagai salah satu cara untuk memecahkan permasalahan setelah seorang pakar. Metode Case-Based Reasoning, Dempster-Shafer, dan Teorema Bayes merupakan metode yang dapat digunakan pada sistem pakar. Penelitian ini bertujuan untuk membangun sistem pakar berbasis website dalam mengidentifikasi hama dan penyakit yang menyerang tanaman manggis berdasarkan gejala-gejala. Ketiga metode tersebut diterapkan performanya dengan melihat nilai akurasinya. Nilai akurasi didapatkan dari perbandingan hasil jawaban sistem per tiap metode dengan hasil pakar. Dari 30 uji data yang dilakukan secara acak, hasil penelitian ini menunjukkan nilai akurasi yang sama untuk Case-Based Reasoning dan Dempster-Shafer, yaitu sebesar 93%, dan Teorema Bayes sebesar 90%. Sistem Pakar yang telah dibangun dapat digunakan oleh petani untuk mengidentifikasi hama dan penyakit pada tanaman manggis.

Intro: Tibial tuberosity avulsion fractures are rare fracture patterns accounting for less than 1% of all pediatric fractures. These fractures occur when there is a sudden unbalancing of forces through the patellar tendon that separates the tibial tubercle from the anterior portion of the proximal tibia. These forces are commonly introduced in sporting activities and show a predominance for adolescent males. Treatment with open reduction internal fixation commonly results in favorable outcomes with minimal complications. In this presentation, we explore a case of a tibial tuberosity avulsion fracture and give an in-depth review of all aspects concerning this fracture pattern. Case Description: A 14-year-old male with no significant past medical history presented via emergency medical services after a ground level fall while playing basketball. Radiographs of the left knee and tibia revealed an Ogden Type III, distracted avulsion fracture of the tibial tuberosity with suprapatellar effusion. Surgical intervention was achieved through open reduction internal fixation of the left tibial tubercle. Discussion: Although a relatively rare fracture pattern, this case demonstrates a classic presentation and treatment of a tibial tuberosity avulsion fracture. This case serves as a reminder that despite the rarity of the injury, a clinician with an appropriate index of suspicion can accurately diagnose and treat this fracture and achieve positive outcomes in returning the patient to pre-injury activities. For those reasons, we provide a comprehensive overview of all aspects regarding this fracture pattern including the anatomy, embryology, mechanism of action, predisposing conditions, treatment considerations, complications and associated injuries.

Since the Coronavirus disease (COVID-19) pandemic, the world of education has been affected by the application of a learning system that is carried out in a blended learning manner. Therefore, this study aims to develop teaching materials in the form of a STEM-based web module using scaffolding to assist the learning process during the covid 19 pandemic. The development of a STEM-based web module using scaffolding is carried out using the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). Data were obtained through interviews with physics teachers. Based on the results of interviews with teachers at one of the senior high schools in Batanghari district, it is known that in offline learning, printed books from the school library are still used. Therefore, we need an electronic module that can be accessed anytime and anywhere to facilitate the learning process. So that researchers will develop a STEM-based web module using scaffolding on straight motion physics material for class X high school. The product produced is in the form of a web containing material for straight motion physics class X SMA/MA based on STEM using scaffolding

This community service activity is motivated by the potential for the spread of the Covid virus which is still happening and the Awipari Village does not yet have health facilities that are balanced with its population. In addition, the use of disinfectants as a protection for families and the environment from the spread of the Covid-19 virus is still not available with natural ingredients and is safe for the environment. This is what training on the manufacture of safe and environmentally friendly disinfectants needs to be done. The main purpose of this community service is to help target partners to be more independent in providing the disinfectant needs that residents need. Furthermore, it can be used as an alternative field to increase household income. The specific target to be achieved in the future is that target partners are able and accustomed to using safe and environmentally friendly basic materials in making disinfectants. Community service activities will be held in September 2021 at the Awipari Village Office, Tasikmalaya City. The methods used are lectures, discussions, and the practice of making disinfectants directly. Community service activities are very well received by partner community groups. The community is enthusiastic and active in demonstrations and discussions and wants this service activity to be routine and continue with various training themes according to community needs.

Community service activities have been carried out for master students of Science Education at the University of Mataram which aimed to provide understanding to students about the development of science teaching materials that can develop students' metacognition. Teaching materials that are able to develop metacognitive abilities are needed by students in the current era of globalization. With the ability of metacognition, it will raise students' awareness of what they really know and one's cognition-regulation functions to regulate their cognitive activities effectively. Knowledge-cognition contains declarative, procedural, and conditional knowledge, while metacognition skills include four skills, namely problem solving skills, decision-making skills, critical thinking skills, and creative thinking skills. Activity participants can understand the material presented which was shown by the ability to answer questions during the discussion. An understanding of proper metacognition was also measured by its ability to fill out a questionnaire that was distributed after the service was complete. A good understanding of metacognition is expected to be a guide in developing metacognition-based teaching materials so that students can develop metacognition abilities.

Karbon aktif dan TiO2 mereduksi SO2 melalui proses adsorpsi dan fotokatalitik. Kedua senyawa ini memiliki efektivitas adsorpsi rendah. Untuk meningkatkan aktivitas adsorpsi dilakukan kombinasi teknik adsorben dan fotokatalitik sehingga adsorpsi dapat optimal. Kombinasi dilakukan dengan membuat komposit karbon aktif/TiO2. Batubara dan semi-kokas dicampur dengan perbandingan 7:3 kemudian TiO2 ditambahkan dengan konsentrasi 1, 3, 6, 9 dan 15%. Karbon aktif/ TiO2 dikarbonisasi pada suhu 600 °C selama 1 jam dan diaktivasi pada suhu 900 °C selama 1 dan 2 jam di bawah aliran gas nitrogen. Hasil analisis fourier-transform infrared (FTIR) spectroscopy menunjukkan intensitas serapan gugus fungsi C=O naik sebesar 49,5% pada karbon aktif/TiO2 6% selama 1 jam dan 33,2% pada karbon aktif/TiO2 3% selama 2 jam. Gugus fungsi basa C=O mereduksi gas SO2 yang bersifat asam. Hasil X-ray diffraction (XRD) ditemukan kristal TiO2 anatas dan rutil. Koeksistensi kristal anatas dan rutil lebih efektif daripada anatas dan rutil fase tunggal. Hasil penelitian ini menunjukkan bahwa karbon aktif/TiO2 meningkatkan aktivitas gugus fungsi permukaan karbon aktif dan membentuk kristal TiO2 anatas dan rutil secara bersama.
