Surface modification of nanoparticles for biological applications is receiving enormous interest among the research community due to the ability to alchemy the toxic nanoparticles into biocompatible compounds. In this study, the agrowastes of Moringa oleifera and Coriandrum sativum were used to surface modify the magnesium oxide nanoparticles and ferric oxide nanoparticles respectively. The agrowaste amended magnesium oxide nano particles (AMNP) and agrowaste amended ferric oxide nanoparticles (AFNP) were characterized using scanning electron microscope, X-ray diffractometer, Fourier transformed-infra red spectroscope to justify the formation and surface modification of nanoparticles with the organic functional groups from the agro wastes. The surface modified nano particles were tested for their biocompatibility and ability to treat the chlorosis in Glycine max. On comparison between the two metal based nanoparticles, AMNP exhibited better chlorosis treating ability than the AFNP. Both the nano particles showed increased potency at minimal amount, 30 μg and the higher concentrations till 125 μg exhibited down run of the potency which was again enhanced from 250 μg of nanoparticle treatment to plants. Further the surface modified nanoparticles were assessed for biocompatibility on human embryonic kidney (HEK-293) cell line which proved that the cell lines are non-toxic to normal human cells. The size of the particles and the concentration is suggested to be responsible for the effective chlorosis treatment and the organic functional groups responsible for the reduction of toxicity of the particles to the plants.

What determines the sustainability of community-based palliative care operations? Perspectives of the social work professionals

E.P. Abdul Azeez,G. Anbu Selvi 한국사회복지학회 2019 Asian Social Work and Policy Review Vol.13 No.3

The palliative care services are least operational in India with exception to the State of Kerala where the movement is widespread. Kerala's model of palliative care is known for its community-based approach and efforts in universalizing the access. This model is unique in the domains of sustainability and mode of interventions. Cognate to the palliative care interventions worldwide, social workers play a cru-cial role in the service delivery of palliative care interventions in Kerala too. In this context, the present study attempted to explore the determinants of sustainable community-based palliative care operations from the perspectives of professional social workers. The study adopted a descriptive qualitative research design using an in-depth interview method. Interviews were conducted with 12 professional social workers engaged in community-based palliative care delivery in the northern and central region of Kerala, India. The interviews were audio-taped, transcribed, and further analyzed applying thematic analysis method. Five major themes, holistic care, community participation, volunteerism, resource mobilization, and socio-political environment, were emerged from the data manifesting as the determinants of suc-cessful palliative care interventions. The result of the study has implications for the policymakers, public health professionals, and social workers who are involved in the development of similar models.

<P>New Schiff base-coated gold nanoparticles (AuNPs) of type AuNP@L (where L: thiolated Schiff base ligand) have been synthesized and characterized using various spectroscopic techniques. The AuNPs and AuNP@L were imaged by transmission electron microscopy (TEM) and were confirmed to be well-dispersed, uniformly distributed, spherical nanoparticles with an average diameter of 8–10 nm. Their potential applications for chemosensing were investigated in UV-Vis and fluorescence spectroscopic studies. The AuNP@L exhibited selectivity for Fe<SUP>3+</SUP>in an ethanol/water mixture (ratio 9 : 1 v/v). The absorption and emission spectral studies revealed a 1 : 1 binding mode for Fe<SUP>3+</SUP>, with binding constants of8.5×<SUP>105</SUP>and2.9×<SUP>105</SUP> M<SUP>−1</SUP>, respectively.</P>

Modelling the effects of factors on the stated preference towards telecommuting in IIUM campus, Gombak

The increase in number of private vehicles has not only taken place in central cities, but has also occurred in university campuses. High use of private vehicles by IIUM community is posing a strain on the ability of the existing road to cope with the increasing traffic volume and parking demand within the campus. Telecommuting is one of the Transportation Demand Management (TDM) measures that aimed at reducing peak hour traffic congestion by allowing commuters to work from home to save their driving time to work, and more importantly to eliminate some vehicle trips. The main objective of this paper is to estimate the effects of the factors on the choice of telecommuting. Three hundred respondents participated in this study through survey questionnaire, which has resulted in a response rate of 67.11%. Findings indicate that 29% and 19.2% of the academic and administrative staff preferred to telecommute, if they were given the option. Multinomial logistic regression was conducted to estimate the effects of socio-economic, trip and work related factors on the preference to telecommute. Parameter estimates on the administrative employees’ preference to telecommute indicate that number of young children, frequency of face-to-face communication and frequency of using email were significant factors in predicting whether an individual is more inclined to choose ‘definitely yes’ towards performing telecommuting as compared to ‘not at all’. As for academic employees, delay time (home-workplace), frequency of face-to-face communication, frequency of using fax machine, frequency of using email and frequency of using mobile network were significant predictors for the preference of ‘definitely yes’ towards telecommuting as compared to ‘not at all’.

Flooding is a serious problem affecting the urban environment and threatens the lives and properties of the urban settlers, including Akure, Ondo State in Southwestern Nigeria where it has become recurrent. The study assessed the impact of flooding on some elements at risk along Ala River in Akure, Ondo State, Nigeria using Remote Sensing and GIS techniques. The land use/land cover change detection of Ala River catchments was carried out using 1984, 2000 and 2015 Landsat images. Each of the classes and the positional accuracy of the river were validated using GPS (Garmin78SC). Buffers were generated around the river channels using high resolution Google Images as input data. The result of LULC showed that there was positive increase in built up land use from 17.65% in 1984 to 24.96% in 2000 and 65.67% in 2015. The results of buffering analysis showed that 105, 214 and 554 buildings with the estimated population of 2520, 5136 and 13,296, fall within 10 m, 20 m and 30 m distance to the river. The study concluded that the incessant occurrence of flood in the study area was as a result of some driving forces such as climate, rapid urbanization, terrain configuration and violation of building regulations that rendered most properties along the flood plain very risky.

“Neither it had social work components nor experiential”: Students' perspectives of online fieldwork practice during COVID ‐19 in India

Negi Dandub Palzor,E P Abdul Azeez 한국사회복지학회 2022 Asian Social Work and Policy Review Vol.16 No.3

This paper explores social work students' perspectives of online fieldwork practice that emerged due to sudden disruption in field placement as a result of the outbreak of COVID-19 in India. We have recruited and interviewed 32 Master's students from five north-Indian universities to participate in the research. The study's findings highlight ill-equipped agencies lacking social work components in online/virtual field placement. Also, ethical dilemmas in working virtually, disconnectedness from the field, and superficial supervision were experienced by the students. The study result implies the urgent need to develop and innovate a pedagogical approach to deal with uncertainties and crises like the COVID-19.
