Published: November 2021

Situasi  pendemi  Covid-19  mengharuskan  orang  untuk  beraktivitas  dari  rumah  termasuk  proses pembelajaran. Pembelajaran dari rumah menjadi peluang besar bagi keluarga untuk memanfaatkan  situasi  ini  sebagai  sarana  penguatan  karakter  anak.  Penguatan  karakter  atau  disebut  juga  pendidikan karakter merupakan hal yang sangat penting agar mencetak manusia yang terpuji, baik  untuk dirinya maupun lingkungannya. Penelitian ini bertujuan untuk mengeksplorasi pemanfaatan  situasi  pandemi  sebagai  sarana  penguatan  karakter  anak  yang  dilakukan  oleh  orang  tua.  Dengan  metode kualitatif, melalui pendekatan grounded theory penelitian ini mengikutsertakan tiga partisipan  yang dipilih secara acak (random sampling). Data dalam penelitian dikumpulkan melalui wawancara  dengan menggunkakan pertanyaan terbuka. Sebelum dilakukan analisis data, terlebih dahulu dilakukan  pengecekan  keabsahan  data  menggunakan  teknik  member  checking,  yang  dilanjutkan  dengan  analisis menggunakan teknik coding. Dari penelitian yang dilakukan ditemukan hasil bahwa situasi  pandemi ini dapat menjadi sarana penguatan karakter anak. Hal ini dilakukan orang tua dengan cara  menciptakan  nilai  mandiri,  tanggung  jawab,  religius,  gotong-royong,  dan  nasionalis  menjadi  momentum  bagi  keluarga  untuk  terlibat  dalam  pendidikan  karakter  dan  membangun  harmonisasi  dengan anak, menjadikan anak belajar pola hidup bersih dan sehat, dan anak berkurang dari aktivitas  lingkungan luar yang kurang bermanfaat.  STRENGTHENING CHILDREN'S CHARACTER IN THE FAMILY IN THE COVID-19  PANDEMIC SITUATION  The  Covid-19  pandemic  situation  requires  people  to  be  active  from  home,  including  the  learning process. Learning from home  is a great opportunity for  families to take  advantage of this  situation as a means of strengthening children's characters. Strengthening character or also called character education is very important in order to produce commendable human beings, both for themselves and their environment. This study aims to explore the use of the pandemic situation as a means  of  strengthening  children's  characters  by  parents.  With  a  qualitative  method,  through  a  grounded  theory approach, this study included three participants who were selected at random (random sampling). The data were collected through interviews using open-ended questions. Prior to data analysis,  the validity of the data was checked using the member checking technique, followed by analysis using  coding techniques. From the research conducted, it was found that this pandemic situation can be a  means  of  strengthening  children's  characters.  This  is  done  by  parents  by  creating  independent,  responsible, religious, mutual cooperation, and nationalist values to become a momentum for families  to be involved in character  education and build harmonization with children,  made  children learn  clean and healthy lifestyles, and reduced from activities outside the environment that are less useful.

Penelitian ini bertujuan untuk membandingkan kondisi edafik, hubungan antara kondisi edafik dan keanekaragaman organisme tanah, serta perbedaan keanekaragaman organisme tanah pada berbagai ekosistem rhizosfer gulma Siam (Chromolaena odorata) yang tumbuh di lahan vulkanik, pesisir, dan karst. Penelitian dilakukan dengan mengambil sampel tanah dari ekosistem rhizosfer gulma Siam di lahan vulkanik, karst, dan pesisir Daerah Istimewa Yogyakarta; mengamati komposisi organisme tanah di laboratorium, yaitu collembola, nematoda, dan mikoriza. Hasil penelitian menunjukkan bahwa tanah pada rhizosfer gulma Siam yang tumbuh di lahan karst menunjukkan tingkat kesuburan tertinggi yang ditunjukkan oleh kandungan N, K, dan C-organik tanah, sedangkan tanah pesisir memiliki kandungan P tertinggi. Tekstur tanah pada rhizosfer gulma Siam lebih berpengaruh terhadap keanekaragaman organisme tanah dibandingkan kandungan hara tanah dan sifat tanah lainnya yang diteliti. Keragaman organisme tanah rhizosfer gulma Siam lebih besar di lahan pesisir dibandingkan di lahan karst dan vulkanik. Implikasi dari hasil tersebut adalah bahwa tanah dengan tekstur berpasir akan lebih bermanfaat bagi pertumbuhan gulma Siam dengan keanekaragaman organisme rhizosfer yang lebih tinggi.ORGANISM DIVERSITY IN THE RHIZOSPHERE OF SIAM WEEDS IN VOLCANIC, COASTAL AND KARST LANDThe research aims to compare the edaphic condition, the relationship between the edaphic condition and soil organism diversity, and the differences of soil organism diversity in different rhizosphere ecosystems of Siam weed growing in volcanic, coastal and karts areas. The research was conducted by taking soil samples from the Siam weed rhizosphere ecosystems in volcanic, karst and coastal areas of the Special Region of Yogyakarta and observing the composition of the soil organisms in the laboratory, including collembola, nematode, and mycorrhiza. The results find that soil from rhizosphere of Siam weed growing in karst area shows the highest level of fertility indicated by the N, K, and C-organic contents of the soil, whereas soil from coastal area has the highest P content. Soil texture in the rhizosphere of Siam weed has more effect on the diversity of soil organisms than the soil nutrient content and other soil properties investigated. The diversity of soil organisms of Siam weed rhizosphere is greater in coastal area than those in karst and volcanic areas. The implication of the results is that soil with a sandy texture will be more beneficial for the growth of Siam weed with a higher diversity of rhizosphere organisms

Published: November 2021

Rimpang Curcuma mangga Val. banyak digunakan sebagai obat herbal antikanker payudara. Penelitian aktivitas sitotoksik terhadap sel kanker payudara banyak dilakukan utamanya untuk minyak atsiri rimpang, dan hanya sedikit penelitian terhadap ekstraknya. Walaupun demikian belum ada yang membandingkan aktivitas sitotoksik dari ekstrak dan minyak atsiri tersebut terhadap sel kanker payudara; meskipun kandungan senyawa keduanya berbeda. Oleh karena itu penelitian ini bertujuan membandingkan aktivitas sitotoksik dari ekstrak dan minyak atsiri rimpang C. mangga Val. secara in vitro terhadap sel kanker payudara MCF7. Ekstrak rimpang dibuat secara maserasi menggunakan pelarut n-heksana; sedangkan minyak atsiri dibuat melalui destilasi uap irisan rimpang selama 5 jam. Uji aktivitas sitotoksik in vitro dilakukan menggunakan metoda MTT Assay. Rendemen minyak dari ekstrak n-heksana rimpang C. mangga Val. adalah 1,15 x 10-2 % sedangkan rendemen minyak atsiri adalah 6,3 x 10-2 %. Hasil uji sitotoksik menghasilkan IC50 ekstrak 106,414 µg/ml (R2=0,9677) dan minyak atsiri 198,557 µg/ml (R2=0,8037). Hal ini menunjukkan bahwa ekstrak rimpang C. mangga Val. lebih sitotoksik terhadap sel kanker payudara MCF-7 daripada minyak atsirinya, karena kandungan ekstrak mayoritas diterpenoid (53,18%) sedangkan minyak atsiri mayoritas monoterpenoid (51,34%).THE COMPARISON BETWEEN THE ACTIVITIES OF CYTOTOXIC EXTRACTS AND ESSENTIAL OILS OF RHIZOME Curcuma mango Val. TOWARD MCF-7 CELLSCurcuma mangga Val. rhizome has been used as herbal anti breast cancer. Researches on cytotoxic activity towards breast cancer cells have been done especially to the rhizome’s essential oil; and only few researches done to the extract. However there is no cytotoxic activity comparation of the extract and essential oil towards breast cancer cells; even tough their substance contents are different. Therefore, this study aimed to compare the cytotoxic activity in vitro of the extract and essential oil of C. mangga Val. rhizomes towards breast cancer cells of MCF-7. The rhizome extract was prepared by maceration using N-hexane; while the essential oil was prepared by steam distillation for 5 hours of the sliced rhizomes. The in vitro cytotoxic test was carried out using MTT Assay. The yield of oil from rhizome extract was 1.15 x 10-2 %; while the yield of essential oil was 6.3 x 10-2 %. The IC50 of extract oil was 106.414 µg/ml (R2=0.9677) and the IC50 of essential oil was 198.557 µg/ml (R2=0.8037). It shows that rhizome extract of C. mangga Val. was more cytotoxic towards MCF-7 than the oil because the majority content of extract were diterpenoids (53.18%) while the oil were monoterpenoids (51.34%).

Hama penting pada tanaman jagung yang baru-baru ini dilaporkan serangannya di Indonesia adalah Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Ukuran partikel mineral mempunyai peranan penting pada keefektifan pengendalian serangga hama. Mineral yang digunakan dalam penelitian ini adalah kaolin. Penelitian ini bertujuan untuk mengetahui pengaruh ukuran partikel mineral kaolin terhadap mortalitas, pertumbuhan dan perkembangan larva S. frugiperda. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 7 perlakuan dan 4 ulangan. Perlakuan terdiri atas formulasi mineral kaolin konsentrasi 4% dengan ukuran saringan 100, 200, 300, 400 dan 500 mesh, kontrol air dan kontrol wetting agent+dispersant agent. Hasil penelitian menunjukkan bahwa ukuran partikel mineral kaolin berpengaruh terhadap mortalitas, lama perkembangan, berat pupa dan kemunculan imago S. frugiperda. Mineral kaolin ukuran partikel 500 mesh menghasilkan mortalitas larva S. frugiperda (28,75%) yang berbeda nyata dengan kontrol (0,00%) pada 48 jam setelah perlakuan. Sementara itu, pada pengamatan 23 hari setelah perlakuan, semua ukuran partikel mineral kaolin yang diuji menyebabkan mortalitas larva S. frugiperda sebesar 31,25 – 51,25%, yang berbeda nyata dengan kontrol (0,00%). Perlakuan mineral kaolin 500 mesh menghasilkan total perkembangan larva dan pupa yang terlama yaitu 22,25 hari, berat pupa paling rendah yaitu 0,1506 g serta kemunculan imago normal yang terendah yaitu 8,00 ekor (dari 20 larva yang diberi perlakuan).

Published: November 2021

Исследовано влияние ионизирующего облучения на образование зарядов на внутренней SiO2-Si (подложка) и внешней SiO2-Sips (затвор) межфазных границах (МФГ) и на пробой затвора МОП-транзисторов. Показано, что с увеличением дозы ионизирующего облучения вблизи внутренней межфазной границы в p- МОП-транзисторах наблюдается монотонный рост положительного заряда, а в n- МОП-транзисторах --- накопление сначала положительного, а при дозах свыше 105 рад --- отрицательного заряда. Вблизи внешней межфазной границы при малых дозах облучения наблюдается накопление положительного заряда, а при дозах > 106 рад --- накопление отрицательного заряда как в p-, так и n- МОП-транзисторах. Вплоть до дозы 108 рад ионизирующее облучение не оказывает заметного влияния на напряжение пробоя затвора как в p-, так и в n- МОП-транзисторах при обеих полярностях смещения. Отсутствие влияния объясняется пробоем по механизму анодной дырочной инжекции. Ключевые слова: ионизирующее облучение, МОП-транзистор, накопление заряда, пробой затвора.

Background

Machine learning–based facial and vocal measurements have demonstrated relationships with schizophrenia diagnosis and severity. Demonstrating utility and validity of remote and automated assessments conducted outside of controlled experimental or clinical settings can facilitate scaling such measurement tools to aid in risk assessment and tracking of treatment response in populations that are difficult to engage.

Objective

This study aimed to determine the accuracy of machine learning–based facial and vocal measurements acquired through automated assessments conducted remotely through smartphones.

Methods

Measurements of facial and vocal characteristics including facial expressivity, vocal acoustics, and speech prevalence were assessed in 20 patients with schizophrenia over the course of 2 weeks in response to two classes of prompts previously utilized in experimental laboratory assessments: evoked prompts, where subjects are guided to produce specific facial expressions and speech; and spontaneous prompts, where subjects are presented stimuli in the form of emotionally evocative imagery and asked to freely respond. Facial and vocal measurements were assessed in relation to schizophrenia symptom severity using the Positive and Negative Syndrome Scale.

Results

Vocal markers including speech prevalence, vocal jitter, fundamental frequency, and vocal intensity demonstrated specificity as markers of negative symptom severity, while measurement of facial expressivity demonstrated itself as a robust marker of overall schizophrenia symptom severity.

Conclusions

Established facial and vocal measurements, collected remotely in schizophrenia patients via smartphones in response to automated task prompts, demonstrated accuracy as markers of schizophrenia symptom severity. Clinical implications are discussed.
Internet Search Results for Older Adult Physical Activity Guidelines: Scoping Review
Authors: Harden Samantha M , Murphy Anna , Ratliff Kathryn , Balis Laura E
Published: November 2021

Background

Older adults seek health-related information through casual internet searches. Yet, researchers focus on peer-reviewed journals and conference presentations as primary dissemination strategies. Representatives of mass media are alerted (passive diffusion) of new studies or recommendations, but the veracity of the information shared is not often analyzed, and when it is, the analysis is often not comprehensive. However, most older adults do not have access to peer-reviewed journal articles or paid subscription services for more reputable media outlets.

Objective

We aimed to determine what information was readily available (ie, open access) to older adults who may casually search the internet for physical activity recommendations.

Methods

We performed a 6-part scoping review to determine the research question and available evidence, and extract data within open-access top hits using popular online search engines. Results were categorized by a dissemination model that has categories of sources, channels, audience, and messages.

Results

After the iterative search process, 92 unique articles were included and coded. Only 5 (5%) cited physical activity guidelines, and most were coded as promoting healthy aging (82/92, 89%) and positive framing (84/92, 91%). Most articles were posed as educational, but the authors’ credentials were rarely reported (ie, 22% of the time). Muscle strengthening and balance components of the physical activity guidelines for older adults were rarely reported (72/92, 78% and 80/92, 87%, respectively) or inaccurately reported (3/92, 3% and 3/92, 3%, respectively).

Conclusions

Inconsistent messages lead to mistrust of science and public health representatives. This work highlights the lack of evidence within existing open-access resources. Further efforts are needed to ensure evidence-based public health messages are in the sources and channels older adults are using to inform their knowledge and behaviors.
A New Digital Assessment of Mental Health and Well-being in the Workplace: Development and Validation of the Unmind Index
Authors: Sierk Anika , Travers Eoin , Economides Marcos , Loe Bao Sheng , Sun Luning , Bolton Heather
Published: November 2021

Background

Unmind is a workplace, digital, mental health platform with tools to help users track, maintain, and improve their mental health and well-being (MHWB). Psychological measurement plays a key role on this platform, providing users with insights on their current MHWB, the ability to track it over time, and personalized recommendations, while providing employers with aggregate information about the MHWB of their workforce.

Objective

Due to the limitations of existing measures for this purpose, we aimed to develop and validate a novel well-being index for digital use, to capture symptoms of common mental health problems and key aspects of positive well-being.

Methods

In Study 1A, questionnaire items were generated by clinicians and screened for face validity. In Study 1B, these items were presented to a large sample (n=1104) of UK adults, and exploratory factor analysis was used to reduce the item pool and identify coherent subscales. In Study 2, the final measure was presented to a new nationally representative UK sample (n=976), along with a battery of existing measures, with 238 participants retaking the Umind Index after 1 week. The factor structure and measurement invariance of the Unmind Index was evaluated using confirmatory factor analysis, convergent and discriminant validity by estimating correlations with existing measures, and reliability by examining internal consistency and test-retest intraclass correlations.

Results

Studies 1A and 1B yielded a 26-item measure with 7 subscales: Calmness, Connection, Coping, Happiness, Health, Fulfilment, and Sleep. Study 2 showed that the Unmind Index is fitted well by a second-order factor structure, where the 7 subscales all load onto an overall MHWB factor, and established measurement invariance by age and gender. Subscale and total scores correlate well with existing mental health measures and generally diverge from personality measures. Reliability was good or excellent across all subscales.

Conclusions

The Unmind Index is a robust measure of MHWB that can help to identify target areas for intervention in nonclinical users of a mental health app. We argue that there is value in measuring mental ill health and mental well-being together, rather than treating them as separate constructs.
Information Warfare in Health Sector – Sifting ‘Real’ from ‘Fake’ News (Preprint)
Authors: Rehman Tanveer
Published: November 2021

UNSTRUCTURED

Information warfare (IW) involves manipulation, destruction, or denying access to information altogether while maintaining the target’s trust. Psychological operations, a type of IW, concern the majority of the public as it aims to degrade their morale through infodemic and fake news. Fake news related to healthcare was present even before the COVID-19 pandemic. A broad range of content comes under it, like communication of inaccurate information with or without any intention to cause harm, mistaken interpretation of satires, and information spread with definitive socio-political agenda. We discuss the various facets of fake news including its burden in the health sector, pathogenesis, the different psychological perspectives of its spread, and strategies to counter it.

Published: November 2021

U radu su navedena teorijska shvatanja relevantna za problem koji se istražuje, tačnije, teorijska shvatanja zlostavljanja djece uopšte i u školi, sa posebnim osvrtom na zlostavljanje učenika i uloga socijalnog radnika u školi. Kada je riječ o zlostavljanju djece u školi, što je u fokusu i našeg istraživanja, možemo izdiferencirati:- međuvršnjačko zlostavljanje – zlostavljanje učenika od strane odraslih. U tom cilju sagledali smo stavove i mišljenja učenika, roditelja i nastavnika o različitim oblicima psihološkog, fizičkog i seksualnog zlostavljanja učenika. Takođe, smo nastojali saznati reakcije odraslih na navedene pojave kao i povjerenje nastavnika i roditelja u odjeljenske starješine i stručnu službu škole, kvalitet odnosa nastavnik-učenik kao i zadovoljstvo učenika i roditelja školom.Cilj istraživanja je empirijsko neeksperimentalno ispitivanje mišljenja, stavova i procjena učenika, nastavnika i roditelja o prisutnosti različitih oblika zlostavljanja učenika osnovnih i srednjih škola,
Ispitivanjem su obuhvaćeni:
– učenici sedmih i osmih razreda u osnovnim i drugog i trećeg razreda
u srednjim školama (1881 ispitanik),
– roditelji ispitivanih učenika (1712 ispitanika),
– cjelokupno nastavno osoblje u školama (1355 ispitanika)
Za potrebe ovog istraživanja, odnosno za dokazivanje posebnih hipoteza, korištene se skale procjene Likertovog tipa.
Dio prikazanih rezultata našeg istraživanja nas upućuje na zaključak da stručna služba škole ima ogroman doprinos u vaspitno-obrazovnom procesu. Nažalost, mali broj socijalnih radnika je zaposleno u osnovnim i srednjim školama u Republici Srpskoj. U narednom periodu potrebno je aktivnije raditi na promovisanju i unaprjeđenju socijalnog rada u školi.

Study on Exhaustion Behaviour of Red Chili on Cotton Fabric
Authors: Bhattacharya Dr. Sumanta
Published: November 2021

Abstract: Dying is a popular practice in textile industry which is prevalent at all parts of the world from the period of ancient civilization. Initially, natural dyes i.e. dye derived from natural resources like vegetables, flowers, minerals, plants etc. were used. Now-a-days, due to technological and scientific innovations synthetic dyes are processed at large scale in the laboratories as it is still one of the most profitable industry globally. However, the rapid utilization of chemicals in textile industry for production of synthetic dyes causes degradation of environment like soil pollution, water pollution etc. Hence, it is necessary to promote the utilization of natural dyes globally. In this paper, the exhaustion of dye extracted from red chillies, one of the most used vegetables same has been studied on cotton fabrics at different temperatures using UV-Visible light spectrophotometer. The colour strength of the fabric before and after application of soap therein are also studied experimentally. Keywords: Natural dye, red chillies, cotton fabrics, exhaustion of dye, absorption.

Abstract: Plastic is the most deadly product which can amplify the climate change affect. It is a solid waste which is durable . Plastic waste is a 400 years of problem, where the plastic production contributes to 99% change in the climate by the burning of fossil fuels and then transportation , the over all process in the production of plastic has resulted in climate change, followed by only 9 % of the plastic waste is recycled . 90 % are thrown into the river , every year 8.6 million tones of plastic waste is dumped in the oceans , seas which has ultimately affected humans we can easting , drinking and breathing plastic resulting in the death of thousand of people across the globe, we need to cut down our production rate and reuse and recycle what ever is possible, we need to adopt the use of jute or cloth bags instead of plastic carry bags , use banana leaves instead of paper plates, use of copper bottles for water . The plastic waste should be properly managed and thrown into the required place or in bins instead on the road side or near the rivers. It is a very important to keep our environment free from plastic which can resolve a quarter of the problem related to climate change.

Comparative Study between R-Pet & Virgin Pet in Terms of Technical Aspect and Market Potential
Authors: Bhattacharya Dr. Sumanta
Published: November 2021

Abstract: The crux of the new trend lies in sustainability and so follows the recyclable products. Polyester is of immense importance as a fibre when it comes to textile and garment, but the type used (Virgin PET) is not an eco-friendly one. Polyester filament extracted from the recycled PET bottles can cater to the unmet need of an eco-friendly substitute to the virgin polyester. A comparative study has been made to analyse whether recycled PET can perform the functionality of virgin PET. The physical properties of both stand out to be the same, signalling the use of recycled PET filament. Recycled PET filament finds it limitation in non-uniform dyeing but the same can be solved through chemical extraction.

Formulation, Development and Evaluation of Gastroretentive Sustained Release Tablets of Lansoprazole Using Natural Polymer
Authors: Sonam , , Jain Nilesh , Banveer Jitendra
Published: November 2021

The goal of this study is to develop a long-acting Lansoprazole delivery system. Lansoprazole belongs to a class of antisecretory drugs known as substituted benzimidazoles, which decrease gastric acid secretion by inhibiting the (H+,K+)-ATPase enzyme system at the secretory membrane of the stomach parietal cell. Due to its mechanism of action, despite its short half-life of 1-5 hours, it can effectively block acid secretion for 24 hours. However, as his plasma concentration falls, the effect will diminish. Lansoprazole will be given as a sustained release tablet to avoid multiple dosing or to reduce the frequency of dose. Lansoprazole was produced and analysed utilizing natural and synthetic polymers such as Xanthan gum, Gellan gum, Carbopol 940 P, and Chitosan. Based on the findings of this experiment, it was determined that formulation F7 demonstrated sustained drug release for up to 12 hours in all developed formulations. Formulation (F1, F2, F3, F4, F5, and F6) were tested in vitro for drug release. For the improved formulation F7, the formulation and release kinetics were estimated. When the regression coefficient values of were evaluated, it was found that Peppas had the highest ‘r2' value, 0.952, indicating that drug release from formulations followed Peppas release kinetics.

Peptic ulcer disease (PUD) is a sore in the lining of the stomach or duodenal mucosa. This study was aimed at evaluating the antiulcer activity of the aqueous extract of Nigella sativa (black seed) and its constitutents. The pharmacognostic properties of the dry seeds were determined. The seeds were extracted using two methods digestion and hydro-distillation. The acute toxicity, phytochemical constituents and the antiulcer evaluation were performed on ethanol-induced ulcer in wistar rats using a standard method. FTIR and GC-MS analysis of the aqueous seed extract was also determined using standard methods. Nigella sativa seed shows the presence of starch grains, lignified tissues, tannins, cellulose, protein and oil globules. The aqueous extract has a high safety margin. The phytochemical studies revealed the presence of saponins, flavonoids, alkaloids, tannins, glycosides, fats and oil. The black seed aqueous and oil extract at 500 mg/kg significantly reduced the acidity, total acidity, and ulcer index, and pH of gastric content when compared with the positive control (Famotidine). The FTIR analysis identified the presence of the following functional groups chloro, ether, amine, carboxylic acid, nitriles, methylene, alcohol, while the GC-MS identified five compounds such as glycerin, n-Hexadecanoic acid, 9, 12-octadecadienoic acid-methyl ester, 9, 12-octadecadienoic acid and 9, 12-octadecadienoyl chloride. The pharmacognostic properties can act as a reliable tool for the standardization of the plant part. This study suggests that aqueous and oil extract possess antiulcer properties. Thus the aqueous and oil extract of black seed can be considered as antiulcer medication traditionally.
