Authors: Sampada Gaire , Bhandari Dilip , Yamamoto Chika , Zhao Tianchen , Tsubokura Masaharu
Published: August 2023

Background

Coronavirus Disease 2019 (COVID-19), a global pandemic, has resulted in millions of deaths worldwide and severely impacted health service delivery systems. Developing countries, including Nepal, faced the risk of health system failure due to limited infrastructures. During the pandemic, Nepal experienced a decline in medical service utilization by pregnant women and a decrease in national child immunization rates. Maternity services and child immunization services had significant consequences, serving as a warning for future pandemics. This article examines the effects of pandemic-induced stay-at-home policies on maternal and child immunization in Nepal.

Methods

A comprehensive literature search was conducted to identify relevant articles on PubMed, Scopus, and Google Scholar. The search terms employed were “maternal mortality in Nepal during COVID-19”, “maternity service utilisation in Nepal during COVID-19”, and “child immunisation in Nepal during COVID-19”. The search was limited to articles published between 2019 and 2022, research conducted in Nepal, and that included maternal mortality, utilisation of maternity services, and child immunisation in the title of the full text.

Results

Factors such as the closure of public transportation and service centres and fear of contamination contributed to a decline in antenatal care visits. The disruption of programs aimed at reducing the Maternal Mortality Rate (MMR) and decreased activities of Female Community Health workers in most parts of the country led to an increase in the maternal mortality rate during the stay-at-home policies. Institutional delivery decreased by 52.4% during the stay-at-home policies compared to the period before. The neonatal mortality rate increased from 13 to 40 per 1000 live births during the pandemic stay-at-home policies. Immunization centres were also closed in Nepal during the early stages of stay-at-home policies, with 50% of centres ceasing services. Measles outbreaks were reported in some parts of the country during the pandemic.

Conclusions

To mitigate future damage, specific guidelines should be established based on regional factors and infrastructure development. Measures such as providing protective equipment and maintaining communication with pregnant women via telephone can help reduce the impact of future pandemics.

Published: August 2023

Traditional tanning practices often result in harmful waste products that pose significant environmental risks, including water pollution, non-biodegradable solids, hazardous emissions, and unpleasant odors. However, this study introduces a simple and effective alternative method for industrial-scale vegetable tanning, with the goal of minimizing environmental pollution. This innovative method eliminates the use of common salt and substantially reduces water consumption. The environmental benefits of this new approach are remarkable. It has led to a significant 70% reduction in water usage, a 25% decrease in energy consumption, and complete elimination of chloride discharge. These changes have also contributed to a notable reduction of 60-70% in tanning and treatment expenses. Furthermore, the leathers produced using this method exhibit comparable physical, chemical, and sensory properties to those produced through conventional tanning practices. This eco-friendly approach not only addresses environmental concerns but also offers economic advantages, making it a sustainable choice for vegetable tanning processes.

Sebuah Proposal bagi Konsep Tindakan Ilahi di dalam Mukjizat dan Hukum Alam
Authors: Winarjo Hendra
Published: August 2023

Abstract. For a long time, Hume's thesis that miracles are a violation of natural laws has had a great influence on the discussions of miracles and natural laws among philosophers and theologians. This article proposes the concept of miracles as divine acts that do not contradict the laws of nature, but rather go beyond the laws of nature and can even be compatible with the laws of nature. By drawing on the concept of miracles and natural laws in relation to the notion of Neo-Classical Special Divine Action (NCSDA) of Jeffrey Koperski, I argue that although miracles and natural law are two distinct forms of divine action, yet miracles can be reckoned as divine acts compatible with natural causes and share the same purpose as divine providence to humans. As a result, rather than contradicting miracles and natural laws, these two forms of divine action actually complement each other to witness the act of God’s power controlling His creation.Abstrak. Tesis Hume bahwa mukjizat adalah pelanggaran terhadap hukum alam sudah sekian lama memiliki pengaruh besar terhadap diskusi tentang mukjizat dan hukum alam di antara para filsuf dan teolog. Artikel ini menawarkan sebuah konsep mukjizat sebagai tindakan ilahi yang tidak bertentangan dengan hukum alam, tetapi melampaui hukum alam dan bahkan juga kompatibel dengan hukum alam. Dengan mendulang konsep mukjizat dan hukum alam dalam kaitannya dengan gagasan Neo-Classical Special Divine Action (NCSDA) dari Jeffrey Koperski, penulis berargumen bahwa sekalipun mukjizat dan hukum alam merupakan dua bentuk tindakan ilahi yang dapat dibedakan, tetapi mukjizat dapat diperhitungkan sebagai tindakan ilahi yang kompatibel dengan penyebab natural, serta berbagi tujuan yang sama dengan pemeliharaan ilahi kepada manusia. Sebagai hasilnya, daripada mempertentangkan mukjizat dan hukum alam, kedua bentuk tindakan ilahi ini justru saling melengkapi untuk menyaksikan tindakan kuasa Allah yang mengendalikan ciptaan-Nya sejarah.

Pada masa pandemi Covid-19, pelaksanaan Posyandu di Kelurahan Teluk menjadi tidak menentu. Berdasarkan data tahun 2021, Kelurahan Teluk memiliki tingkat kedatangan ibu ke Posyandu yang paling rendah, yaitu 78,1%. Hasil observasi pelaksanaan di beberapa Posyandu wilayah Teluk menunjukkan adanya ketidaklengkapan KMS terutama pada kolom N/T sehingga tidak ada penyampaian informasi hasil penimbangan balita kepada ibu balita. Hal ini dapat mempengaruhi status gizi balita. Kader perlu untuk kembali pemahaman dan kemampuannya dalam pemantauan dan pendokumentasian pertumbuhan balita. Metode yang digunakan berupa pelatihan dengan brainstorming dan simulasi pengisian KMS. Peningkatan pengetahuan diukur dengan perubahan skor pre dan post-test sedangkan kemampuan kader diobservasi secara proses dan dokumen. Uji Wilcoxon diperoleh hasil tidak adanya perbedaan skor pre dan post-test secara statistik (p>0,05). Meskipun demikian, terdapat peningkatan rata-rata skor sebelum dan sesudah pelatihan dengan nilai positif sebesar 3,4%. Observasi proses dan dokumen menunjukkan kader Posyandu di Wilayah Kelurahan Teluk mampu untuk mengisi Kartu Menuju sehat (KMS) sesuai prinsip pengisian KMS yang benar.

This paper explores the relationship between philosophy and politics in the twenty-first century, using the thought of Jean Baudrillard, one of the most prominent intellectuals of the 20th century, taking into account the idea of what it means to be human. The study will argue that the human being is a creature capable of aestheticization as the capacity to express something with the help of other things. After setting forth such a definition of the human being as a basis, the study will then address the relationship between philosophy and politics. In this context, the historical foundations of this relationship will be presented within the framework of the study. Then, the state of philosophy-politics interaction in the twenty-first century will be discussed in the light of historical themes and Baudrillard's ideas. Finally, an evaluation of all the explanations will be made in relation to some of the problems that are visible today and potential approaches will be put forward to rectify the problems in this connection.

Çevre kirliliği ve ekonomik büyüme arasındaki ilişkinin yanı sıra literatürde ekolojik ayak izi ile ekonomik büyüme arasındaki ilişki de son zamanlarda yoğun ilgi gören bir konu haline gelmiştir. Bu çalışmanın amacı Türkiye’de 1961-2018 yılları arasında ekonomik büyüme ile ekolojik ayak izi arasındaki ilişkiyi, Granger nedensellik analizi kullanarak incelemektir. Bu analiz için, ekonomik büyüme ve ekolojik ayak izinin orijinal verilerinin yanı sıra, Azami Çakışan Kesikli Dalgacık Dönüşümü (MODWT) yöntemi ile frekanslara ayrıştırılan verilerin kısa, orta ve uzun dönem bileşenleri yeniden yapılandırılmıştır. Analiz sonuçları, orijinal verilere dayanarak iki serinin arasında nedensellik olmadığını göstermektedir. Ancak, kısa dönem Granger nedensellik sonuçları, orijinal serilerden elde edilen sonuçlarla çelişmekte ve karşılıklı nedensellik ilişkisi olduğunu göstermektedir. Nedensellik ilişkisi; orta dönemde kaybolurken, uzun dönemde ekonomik büyümeden ekolojik ayak izine doğru tek yönlüdür.

Hidroponik merupakan teknik budidaya tanaman tanpa menggunakan media tanah, melainkan menggunakan air sebagai media tanamnya. Salah satu keunggulan hidroponik adalah memiliki nilai jual yang tinggi serta tidak memerlukan lahan yang luas. Agar nilai jual tanaman hidroponik tinggi tentunya kualitas tanaman hidroponik yang dihasilkan memiliki kualitas yang baik, untuk itu tanaman hidroponik harus dapat tumbuh kembang dengan baik. Untuk dapat tumbuh kembang dengan baik tentuya harus diperhatikan faktor-faktor seperti kebutuhan nutrisi, pH, suhu dan intensitas cahaya disekitar lingkungan hidroponik. Dengan menggunakan Internet of Things (IoT) dapat dilakukan monitoring dan controlling terhadap faktor-faktor tersebut, sehingga tanaman hidroponik dapat tumbuh kembang dengan baik. Pada Penelitian ini menggunakan dua sample tanaman yang berbeda jenis yaitu pakcoy dan selada. Microcontroller sebagai pengendali utama dari keseluruhan komponen IoT. Sensor yang digunakan yaitu sensor TDS, sensor PH, sensor Suhu dan sensor cahaya serta perangkat hardware pendukung IoT lainnya. Disamping perangkat hardware sistem IoT ini menggunakan software Arduino Uno dan Framework Codeigniter yang menghasilkan tampilan user interface sehingga mudah digunakan oleh pengguna, seperti perangkat smartphone. Pengujian kepekatan nutrisi dengan sensor TDS menggunakan MAPE sehingga mendapatkan hasil 0,13% untuk tanaman salada dan 0,07% untuk tanaman pakcoy sedangkan untuk pengujian pH air mendapatkan hasil  0,37% untuk tanaman salada dan 0,14 % untuk tanaman pakcoy. Karena nilai MAPE kurang dari 10% maka menunjukkan bahwa kemampuan alat IoT untuk memonitor dan controlling kepekatan nutrisi dan kandungan pH pada tanaman hidroponik sangat baik. Dengan adanya teknologi IoT pada tanaman hidroponik dapat memonitor dan mengontrol tanaman secara otomatis agar tanaman hidroponik tetap tumbuh dengan baik tanpa perlu direpotkan untuk melakukan pengecekan kadar nutrisi dan pH setiap saat.
