Nursing Care of Low-Risk Newborns in Low Resource Setting: Nurses' Aides May Bridge the Gap at Community Hospitals
Authors: Daga Subhashchandra 
Published: January 2022

Objective: To study the role of a nurses' aide in the care for newborns weighing between 1500 and 2000 g at birth in a low resource setting.
Study Design: Observational.
Setting: The General hospital in 1994-95, in a public sector, located in a remote area in India
Intervention: A female ward assistant with seven years of schooling trained, on-the-job, to keep babies warm, initiate maternal breastfeeding, and to detect rapid breathing. The nursing staff from the pediatric ward supervised her performance. A separate "warm room" appropriately heated for preterm and sick babies became a makeshift nursery. The nursing staff administered enteral feeding, oxygen, and antibiotics. Services of the resident doctors or general duty medical officers were not available.
Results: The survival rate was nearly 100% for babies with birthweights between 1,500 and 2,000 g (none referred out).
Conclusions: A nurses' aide may facilitate the delivery of special care for newborns where nursing personnel are grossly inadequate and saving babies weighing between 1,500 and 2,000 g may need minimal inputs. It may be worthwhile to target 1,500 and 2,000 g birthweight categories even when resources are meager.
What is already known about this subject?

Low resource settings face staff shortages, especially nursing staff.
Health workers with midwifery skills can deliver nearly 90% of essential care services for maternal and neonatal health.
A substantial proportion of neonatal deaths occur among moderately low birth weight babies.

What does this study add?

It is possible to train a semi-literate person to facilitate early breastfeeding and to keep a baby warm.
A large proportion of deaths among babies with birthweight ranging from 1500 to 2000 g are preventable with meager resources.

How might this impact on clinical practice or future developments?
The facilities facing shortage of nursing staff in low resource settings, may employ nurses’ aide to deliver basic newborn care.

Authors: Dinwoke Onodagu P. , Henry Aginam C. , Franklin Uzodinma C. 
Published: January 2022

This paper analysed the flexural behaviour of SSSS thick isotropic rectangular plates under transverse load using the Ritz method. It is assumed that the line that is normal to the mid-surface of the plate before bending does not remain the same after bending and consequently a shear deformation function f (z) is introduced. A polynomial shear deformation function f (z) was derived for this research. The total potential energy which was established by combining the strain energy and external work was subjected to direct variation to determine the governing equations for the in – plane and out-plane displacement coefficients. Numerical results for the present study were obtained for the thick isotropic SSSS rectangular plates and comparison of the results of this research and previous work done in literature showed good convergence. However, It was also observed that the result obtained in this present study are significantly upper bound as compared with the results of other researchers who employed the higher order shear deformation theory (HSDT), first order shear deformation theory (FSDT) and classical plate theory (CPT) theories for the in – plane and out of plane displacements at span – depth ratio of 4. Also, at a span - depth ratio of and above, there was approximately no difference in the values obtained for the out of plane displacements and in-plane displacements between the CPT and the theory used in this study.

The world population is continuously growing at a rapid rate, so a great challenge for this time is to ensure the security of food and nutrition for this increased population seeking for new crop as a source of food and nutrition. In such state mushrooms, a great source of protein, can be a favor that can be cultivated by landless people using agricultural waste material. The research work was about to analyze the effect of three lighting conditions namely dark condition (C1), medium lighting condition (C2), and sunlight (C3) on growth, yield, and nutrient content of pleurotus ostreatus (white oyster mushroom). Vertical farming technology was applied in mushroom production in order to minimize the land use. Three vertical structures each of three layers were used. This study also encompassed the effects of different layers (bottom later L1, middle layer L2, top layer L3) on the growth and yield of mushroom. The findings of this investigation revealed that there were significant differences in growth and yield at different conditions and structural layers. The highest average growth and yield (stalk height 3.87 cm, cap size 11.89 cm, stipe size 2.65 cm, crops per bag 15.78, fresh weight 60.03 g, and dry weight 17.03 g) was observed in dark condition (C1). On the other hand, lowest growth, and yield (stalk height 1.59 cm, cap size 3.67 cm, stipe size 1.51 cm, crops per bag 4.22, fresh weight 18.38 g, and dry weight 4.47 g) was found in sunlight (C3). Oyster mushroom cultivated in dark condition C1 also have high nutrient content. The study suggested that maintaining the absolute darkness is capable of producing high-quality white oyster mushroom.

DPT immunization is the basic immunization used to prevent diphtheria pertussis and tetanus. According to data from the Bandar Lampung City Health Office from 30 health centers in Bandar Lampung, the Korpri Puskesmas in Sukarame District is the health center with the lowest complete basic immunization coverage, which is 60.8% in 2015. The low immunization coverage rate is inseparable from health behavior and parental knowledge about DPT immunization. Purpose of this study to determine the relationship between the level of mother's knowledge about DPT immunization in infants with the prevention behavior of diphtheria pertussis and tetanus at the Korpri Puskesmas Bandar Lampung in 2020. This study used an observational and analytic type of study with a cross sectional approach and a questionnaire interview method. The sample used in this study were mothers who had babies in the work area of the Korpri Bandar Lampung Community Health Center in 2020. Data analysis used Chi-Square. The result It is known that 7 mothers (77.8%) have bad knowledge about DPT immunization and bad behavior towards DPT disease prevention, as many as 2 mothers (22.2%) have bad knowledge about DPT immunization and good behavior towards DPT disease prevention. A total of 28 mothers (33.3%) had good knowledge about DPT immunization and bad behavior towards DPT disease prevention, as many as 56 mothers (66.7%) had good knowledge about DPT immunization and good behavior towards DPT disease prevention. Chi-square test results obtained p-value = 0.024 (p ≤ 0.05), which means that there is a relationship between the level of maternal knowledge and the prevention behavior of diphtheria, pertussis and tetanus.

Development and Evaluation of a Chinese Character Educational Board Game for Non-Native Learners
Authors: Chai Chuen Lee , Mohd Yusof Nor Azrina 
Published: January 2022

There is no doubt that knowing Chinese gives graduates a competitive advantage. The ability to communicate fluently in Chinese has long been a requirement for Chinese employers, particularly those looking to do business in China's e-commerce market. Non-native learners must master four fundamental abilities in order to become literate in the Chinese language: listening, reading, writing, and speaking. Previous research has found that writing Chinese characters is frequently the most difficult task for both non-native and native learners. The issue arises during the process of learning Chinese characters and excessive use of gadgets, while online learning inspires both researchers to create a Chinese educational board game dubbed the LiSCReW Family Board Game (LiSCReW). LiSCReW is an acronym for Listen, Speak, Count, Read, and Write. The purpose of this study is (i) to develop and evaluate the effectiveness of the LiSCReW for learning Chinese characters; and (ii) to share non-native learners' perspectives and experiences while playing LiSCReW during a one-day exhibition at Universiti Teknologi MARA (UiTM) Johor Campus. To facilitate playtesting and evaluation of the board game, a total of 22 students from UiTM Johor were conveniently selected. The findings indicate that the LiSCReW board game is an effective educational tool for learning Chinese characters. The results show that respondents are more confident in recognising Chinese characters (90.9%), pronouncing Chinese characters (68.2%), reading Chinese characters (54.6%), and applying the Chinese characters they learned while playing LiSCReW to their Chinese test (77.2%). The findings can be used to guide future research into the empirical testing of Flow Theory's applicability among a large number of respondents.
