Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo IPB, Darmaga Bogor dari bulan Agustus hingga Desember 2013. Tujuan penelitian ini untuk mengevaluasi pengaruh aplikasi biomulsa Arachis pintoi dalam peningkatkan pertumbuhan dan produksi tanaman oyong (Luffa acutangula) dan pakcoy (Brassica chinensis) serta dampaknya terhadap kualitas tanah. Penelitian ini terdiri dari dua percobaan yang dilakukan secara berurutan menggunakan bedeng yang sama. Musim tanam petama bedeng ditanam tanaman oyong, sedangkan musim tanam kedua dengan tanaman pakcoy tanpa pengolahan tanah namun dilakukan penggantian mulsa plastik hitam perak (MPHP) sesuai jarak tanam pakcoy. Perlakuan terdiri atas tanpa mulsa, mulsa plastik hitam perak, biomulsa Arachis pintoi. Hasil penelitian menunjukkan bahwa penggunaan biomulsa Arachis pintoi setelah dua musim tanam menunjukan penurunan nilai C-organik paling kecil dibandingkan perlakuan lain. Perlakuan MPHP pada tanaman oyong meningkatkan pertumbuhan vegetatif yaitu pada parameter panjang tanaman, jumlah cabang dan bobot brangkasan dengan respon yang sama dengan perlakuan tanpa mulsa, sedangkan pada parameter bobot akar perlakuan MPHP memiliki nilai paling tinggi dari perlakuan lainnya. Perlakuan MPHP terhadap komponen produksi buah/tanaman dan jumlah buah/tanaman memiliki respon yang paling baik dibandingkan perlakuan lainnya. Secara umum perlakuan MPHP memiliki nilai terbaik dibandingkan dengan perlakuan tanpa mulsa dan biomulsa A. pintoi terhadap tinggi tanaman, jumlah daun, bobot akar, dan bobot panen.

Authors: Kayode-Iyasere Edith , Odiase Francis Ehidiamen 
Published: May 2020

Background: Stroke is a significant cause of hospital admissions, disability and mortality, but there is a lack of information on stroke in parts of the southern region of Nigeria. Objective: To analyze the frequency of stroke admissions, clinical presentations, risk factors, stroke types and outcomes over seven years, in a secondary level hospital in southern Nigeria. Methods: This was a retrospective study. The hospital record of patients hospitalized between January 2006 and December 2012 at the Central Hospital, Benin-City with the diagnosis of stroke based on the World Health Organization (WHO)-clinical criteria, were studied. Results: Four hundred and nineteen patients with stroke were hospitalized during the study period; this accounted for 3.1% of all the medical admissions. The mean age was 62.4 ± 13.6 years. There were 222 (53%) males and 197(47.0%) females. Ischaemic stroke occurred among 71% of cases; others included intra-cerebral haemorrhage (26%) and subarachnoid haemorrhage (3.1%). The main presenting features included hemiparesis (69%) and sudden loss of consciousness (27.2%). The risk factors included hypertension (84%) and diabetes mellitus (12.2%). The 7, 14 and 30 days case fatality rates were 21.2%, 25.5% and 30.8% respectively. A higher case fatality rate was recorded in haemorrhagic stroke compared to ischaemic stroke (68.8% vs 24%, p = 0.0001). Conclusion: Stroke was a significant cause of mortality amongst medical admissions and hypertension was the most common risk factor. Closer attention to the risk factors for stroke may likely help to reduce the burden of stroke.

Published: May 2020

Background: The incidence of neonatal macrosomia is on the increase in many parts of the world. The impact of the condition on baby and child health has not received adequate research attention. Objective: To determine the prevalence, baby and maternal characteristics, the pattern of neonatal morbidity and perinatal outcome of macrosomia. Methods: A retrospective study of all singleton deliveries with birth weight ≥ 4.0 kg was conducted at a tertiary facility in the south-western part of Nigeria between January 2013 and December 2014. Results: Eighty-eight newborn babies were macrosomic out of 1854 deliveries, resulting in a prevalence rate of 4.7%. The male-to-female ratio was 1: 0.54, while the mean (±SD) birth weight was 4.23 ± 0.29 kg. There was no significant difference in the mean birth weights of the male and female babies (t = 1.24, p = 0.218). The mean maternal age was 31.7 ± 5.1 years. Multiparous mothers had the highest proportion of macrosomic babies, while a majority of mothers (77.3%) were either overweight or obese. One-minute Apgar score <7 was observed among 28 (31.8%) babies. Twenty-three (26.1%) babies were hospitalized for further management. Birth asphyxia, hypoglycaemia and hyperbilirubinaemia were the leading morbidities. The perinatal mortality rate for macrosomic babies was 102.2 per 1000 total births. Conclusion: The incidence of neonatal macrosomia is relatively low in our study population but falls within the range of prevalence rates reported from other parts of the country. Birth asphyxia, hypoglycaemia and hyperbilirubinemia are common morbidities among affected babies.

Authors: Ogundipe Olufemi , Njokanma Azuka Ralph 
Published: May 2020

Background: The Post-Operative Symptom Severity (Posse) score is useful in the assessment of patients after third molar surgery. Objective: To evaluate patients' perceptions of quality of life after surgical extraction of an impacted mandibular third molar by comparing their Post-operative Symptom Severity (PoSSe) scores at Post-operative Weeks (POW) 1 and 4. Methods: Seventy patients (age 18 to 35 years) at the Out-Patient Department were enrolled in a prospective study prior to surgical removal of third molars. Each patient was given a PoSSe questionnaire to be completed at POW 1 and POW 4. The scale assessed recovery in seven key domains on patients’ subjective feeling about pain, eating, speech, sensation, appearance, sickness and interference with daily activities. Results: All but one patient returned completely filled questionnaires. The mean age of the study population was 25.7 ± 4.5 years. The mean PoSSe score at POW 1 and POW 4 were 35.0 ± 7.2 and 33.2 ± 6.9 respectively with statistically significant difference (p = 0.010). The PoSSe score was higher among males compared to females at POW 1 (37.2 ± 7.6 vs 33.5 ± 6.6) and also higher among males at POW 4 (33.8 ± 9.4 vs 32.7 ± 4.6). Conclusion: The severity of symptoms was perceived to be worse at POW 1 when compared to POW4 but the symptoms were still severe at POW4. There is a need for surgeons need to pay more attention to management of symptoms in the post-operative intermediate period.

Published: May 2020

Although the internet penetration has reached 64.8% of the population (APJII, 2019), yet the digital divide is still a major issue in Indonesia; especially among the poor. This paper aimed to study and to explain the risks of digital governance implementation in the poverty reduction policies; with the study on how the poor obtains and shares public information in the digital governance era as the focal point. The study was conducted in a city in Indonesia that has been awarded with the Smart City Award. The data was analyzed using descriptive statistics and Social Network Analysis. The study found that some of the poor groups are adapting to the digital governance with the help of the social network in their community; and some of them are alienated digitally. They have been at risk of become marginalized both socially and economically. This paper suggested further studies focusing on the information demand among the poor and the use of new communication technology in the poverty reduction policy making that is inclusive.
Mathematical analysis of a penalisation strategy for incompressible elastodynamics
Authors: Caforio F. , Imperiale S. 
Published: May 2020

This work addresses the mathematical analysis – by means of asymptotic analysis – of a penalisation strategy for the full discretisation of elastic wave propagation problems in quasi-incompressible media that has been recently developed by the authors. We provide a convergence analysis of the solution to the continuous version of the penalised problem towards its formal limit when the penalisation parameter tends to infinity. Moreover, as a fundamental intermediate step we provide an asymptotic analysis of the convergence of solutions to quasi-incompressible problems towards solutions to purely incompressible problems when the incompressibility parameter tends to infinity. Finally, we further detail the regularity assumptions required to guarantee that the mentioned convergence holds.

BACKGROUND: Calcium and vitamin D deficiency is common among Iranian women of childbearing age and poses adverse effects on pregnancy outcomes. The aim of the current study was to determine the prevalence of vitamin D and calcium in a sample of Iranian pregnant women and to assess its correlation with the feto-maternal outcomes. METHODS: In this prospective cross-sectional study, a sample of pregnant women between 15 to 45 years who were in the third trimester were recruited from a number of hospitals in Tehran. Data were collected by the means of a self-developed questionnaire, interviews, physical examination, and paraclinical tests including measuring the serum level of calcium, vitamin D, parathormone (PTH) and phosphorous (Pi). The questionnaire obtained information on age, level of education, socio-economic status, parity, gravidity, calcium intake during pregnancy, as well as feto-maternal outcomes. RESULTS: We included a total number of 233 singleton pregnancies. Most of the subjects (58.4%) had vitamin D deficiency and 12.0% suffered from severe vitamin D deficiency. Vitamin D deficiency was adversely associated with the years of education (p= 0.007), serum level of parathormone (p< 0.001). The Metabolic Equivalent of Task (MET) (p< 0.001), the exercise sequence per week (p< 0.001), sun exposure (p< 0.001), higher rate of sunscreen usage (p= 0.011) and higher BMI (p= 0.005). Vitamin D deficiency was associated with higher rate of cesarean delivery (p= 0.024), higher rate of diastolic hypertension (p= 0.019), higher rate of neonatal jaundice (p= 0.009) and higher rate of neonatal respiratory infections (p< 0.001). Serum level of PTH was a significant risk factor for severe vitamin D deficiency while calcium D supplementation, MET and sunscreen were significant protective factors. CONCLUSION: The prevalence of vitamin D deficiency during pregnancy among Iranian women is extremely high and is associated with adverse pregnancy outcomes including cesarean delivery, neonatal jaundice and neonatal respiratory infections. Low vitamin D supplementation and sun exposure, lack of physical activity and high BMI are the etiologies. Increasing the knowledge along with vitamin D supplementation during the pregnancy is recommended in Iranian population.

Objetivo. Identificar el nivel de conocimiento sobre el virus del papiloma humano (VPH) en estudiantes de secundaria pública posterior a una intervención educativa de enfermería. Metodología. Estudio cuantitativo, cuasiexperimental, longitudinal. Muestra no probabilística por conveniencia de 132 estudiantes de una secundaria pública del estado de Aguascalientes, con previo consentimiento informado de los padres o tutores. Se aplicó el instrumento para determinar el conocimiento de los interrogados acerca del VPH, constituido por 15 ítems. Con un puntaje de 13-15 se califica como excelente y de 1-3 puntos como insuficiente; fue aplicado a través de dos tiempos, antes y después de la intervención, teniendo aceptable confiabilidad, con un alfa de Cronbach 0,754. Para el procesamiento de datos y resultados se utilizó el programa SPSS Statistics versión 22.0- 2013 Resultados. Antes de la intervención educativa, los adolescentes tuvieron un nivel de conocimiento regular del 40.2%; posterior a la intervención educativa, el nivel de conocimiento que predominó fue excelente en el 68.9% de ellos. Las edades (pre-post intervención educativa) de la población osciló entre los 13 a 15 años de edad, predominando 14 años en el 72.7%. Conclusión. Mediante la aplicación de la intervención educativa de enfermería a los adolescentes de la secundaria pública, se obtuvo mejoría en el conocimiento sobre el virus del papiloma humano. Las intervenciones educativas de enfermería sobre VPH favorecen cambios en las actitudes, en el comportamiento durante la adolescencia e impactan durante toda su vida, ya que, el desconocimiento de las consecuencias de la actividad sexual sin protección, llevan a los adolescentes a incurrir en prácticas de riesgo para la salud.

Issues with Senior Workers in Hong Kong Construction Industry: Preliminary Observations and Intervention Opportunities
Authors: Koh Tas Yong , Rowlinson Steve , Pollock Stephen 
Published: May 2020

There is an increasingly larger proportion of workforce 50 years of age or older. This ageing trend is prevalent in the Hong Kong construction industry. The implications of this ageing trend for the construction industry are the decline in workforce productivity due to old age, compromised health, safety, and well-being; and the shortage of workforce. Coupled with various organisational and institutional shortcomings in the industry that lead to unfavourable working environment, these situations not only negatively affect the economic viability of the construction industry but also give rise to other psychosocial problems experienced by the older workers. Despite these situations, we know very little of the conditions older construction workers experience in the construction industry.There is therefore a need to investigate such issues and propose possible interventions to improve the working conditions of the senior workers. With these objectives, in this paper, we first report the findings of a small scale survey on the care of older workers in Hong Kong construction industry, and second propose potential intervention by combining the findings of the survey and our industry observations of the practices implemented by progressive contracting firms in Hong Kong. The findings reveal that despite the industry under appreciation of the ageing workforce, there are interventions implemented by progressive contracting firms that can potentially provide health and safety protection to the workforce of all ages although these firms are small in number. This article is an extended version of a conference paper that appeared as Koh et al. (2019).

Published: May 2020

Minimum Miscibility Pressure (MMP) is regarded as one of the foremost parameters required to be measured in a CO2 injection process. Therefore, a reasonable approximation of the MMP can be useful for better development of injection conditions as well as planning surface facilities. In this study, the impact of asphaltene content ranging from 3.84 % to 16 % on CO2/heavy oil MMP is evaluated. In this respect, slim tube miscibility and Vanishing Interfacial Tension (VIT) tests are used. Regarding the VIT test, the Interfacial Tension (IFT) is measured by means of two methods including pendant drop and capillary apparatuses, and thereafter the MMP measurement error between slim tube and VIT methods are calculated. Based on the results, by increasing the asphaltene content, the measured MMP by slim tube method increases linearly while that by VIT follows no clear trend. The results also indicate that there is an asphaltene content range within which the MMP error between slim tube and VIT tests is minimized. IFT measurement by pendant drop and Capillary Glass Tube (CGT) methods show that by increasing asphaltene content up to 10.15 %, IFT declines, whereas for further increase in content, IFT increases because of the irregular dispersion of asphaltene in oil droplets.
