Abstract

Traditionally economists in earlier and middle of 20^th century discussed about risks and uncertainty and related to theory of profits. Though risk is assumed to be predictable, measurable and insurable, uncertainty has subjectivity and largely remained "unknown" in statistical sense. Applications of mathematical and statistical techniques to risk definition, measurement and control through measurement of variability of outcomes and relate it with financial and corporate performance were popular in financial literature. Adoption of risk perspectives in supply network assumed greater importance with globalisation of business and movement of production to eastern part of the globe. Initially, supply risk was limited to upstream part of supply chain network and totality approach to supply chain risk gained more importance over the years. Happening of major disruptions across the globe due to terror attacks, geo-political changes, natural disasters like swine flu and Tsunami led to application of supply chain risk and uncertainties. There were discussions on an event based outcomes were considered uncertain event but raised debates about risk, uncertainty and return management. In this paper, authors have considered recent torrential rains and flooding at Chennai leading to disaster have been analysed for understanding managerial perspectives.

Abstract

The application of Ti–6Al-4V alloy in the fields of biomedical and aerospace industries attracts the manufacturing engineers to understand the behavior of alloy during machining. Ti–6Al-4V alloy posses high specific strength and corrosion resistance and besides its advantages they poses challenges in machining due its low thermal conductivity nature. The heat generated during machining is dissipated through cooling medium and cutting tool. Considering the situation detailed experiments are planned for turning of Ti–6Al-4V alloy with varies cutting speed, feed rate and depth of cut. The cutting tool is cooled with the process of evaporative cooling technique by using the water soaked banana fiber pad along with fan and flooded coolant. This method dissipates 39.51% of heat generated during cutting operation at parameter combination of 1200 rpm cutting speed, 1.5mm/rev feed rate and 0.6 mm depth of cut. The lowest average surface roughness (R_a) is recorded at parametric combination of 1200 rpm cutting speed, 0.25mm/rev feed rate and 0.6 mm depth of cut for banana fiber cooled tool. The use of banana fiber resulted in lesser R_a of 0.42μm. Further studies with multi-pad evaporative cooling facilitate for increased tool heat dissipation.

Abstract

A scale measuring the degree of affect of the students towards the agricultural education system was developed. Sixty five possible, scrutinized statements were examined to assess their degree of favorability using a five point continuum with respect to their capacity to measure the attitude of the respondents towards agricultural education system. The S- value and Q- value of each statement were found. Equal appearing interval method was used for developing the scale. The statements were selected and the validity and reliability of the scale was tested. The scale developed consists of both positive (6) and negative (4) statements. Thus, the final scale was developed which could measure the students' level of attitude towards agricultural education system. This study was implemented among 114 number of final year B. Sc. (Agriculture) students of Tamil Nadu Agricultural University, Coimbatore, to assess their level of attitude towards the present agricultural education system. The results showed that most of the students were found distributed between medium to high level of attitude.

Keywords

Abstract

Aim of the study is to find the effectiveness of Modified Trunk Dissociation Retrainer in improving trunk control in infantile hemiplegic subjects and objective is to determine trunk control following trunk dissociation retraining in infantile hemiplegic subjects. Sample size is 10 selected based on inclusion and exclusion criteria with convenient sampling method from out-patient department of SMCH, Chennai. Study design: Quasi experimental study. Materials required: Modified Trunk Dissociation Retrainer. Outcome measures: trunk control measurement scale. A baseline measurement of trunk control is taken before intervention. Intervention was given by researcher for a duration of 3 weeks as 5 days/week. After the 3^rd week of intervention first post-test was taken and second post-test in the 6^th week. Analysis of post-test values showed that there was significant difference between pre-test and post-test values and also the results sustained from post-test I and post-test II values. Hence the conclusion the study was that the Modified Trunk Dissociation Retrainer is an effective tool to improve trunk control in subjects with infantile hemiplegia.

Keywords

Modified Trunk Dissociation Retrainer, Infantile Hemiplegia, Trunk Control Measurement.

Abstract

Duchenne muscular dystrophy (DMD) is a rare genetic disorder that affects about 0.8 million Indian children. The incidence rate of 1:3500 male births is the most common form of all muscular dystrophies. Covid-19 pandemic cause profound devastation to the lives of DMD children. The muscles are weaker in DMD, and the children are more prone to lung infections. Coronavirus (COVID-19) is a severe lung infection that disturbs the entire function of the World. DMD already has weakness in major muscles, including the respiratory. So, the study aims to identify the effect of low-intensity aerobic exercises in children with DMD. This is a home-based pilot study with 11 DMD children and wheelchair dependent since, for ten years, they have been on continuous rehabilitation and monitoring. When the pandemic was declared in India in March 2020, all children were given clear notes on the disease and its severity to the parents. Self-created quarantine exercise protocol, which includes Limb exercises, breathing exercises, trunk mobility exercises, and positioning, was taught along with a logbook given to all the children. Video calls, and WhatsApp videos, were used to monitor them regularly. The physiotherapist made a personal visit in June 2020 to review the exercises, and subsequently on Aug 20, Oct 20, Dec 20, Feb 21, and May 21. Observations are detailed here. The infection rate was 3 out of 9, and they got admitted to the hospital for other illnesses. All the children noted Flu infection but recovered within ten days without hospitalization. The parents monitored their SPo2 and temperature and updated them in the logbook. A lung function test was done using a handheld incentive spirometer during the personnel visit by the therapist and found satisfactory. The study concluded a significant improvement in the DMD children following low-intensity and quarantine exercises.
