Naveena Thomas,Sudhin Karuppali 대한소아청소년정신의학회 2022 소아청소년정신의학 Vol.33 No.1

Objectives: Children with attention-deficit/hyperactivity disorder (ADHD) tend to be noisy and violate rules with their disruptive behaviors, resulting in greater difficulties with off-task behaviors and being at risk for social refusal. The visual activity schedule (VAS) intervention program is a frequently used method to teach multiple skills involving on-task, use of schedules, transition behaviors, social initiation, independent play skills, classroom skills, and academic skills. The current systematic review aimed to examine the efficacy of using VAS intervention in reducing problem behaviors in children with ADHD between 5 and 12 years of age. Methods: Systematic searches were conducted using two electronic databases (PubMed and Scopus) to identify relevant studies published in English between 2010 and 2020. Four studies met the inclusion criteria: two studies examined the effect of schedule-based tasks and the use of an iPad on classroom skills, while the other two examined randomized clinical trials (RCTs) of psychosocial treatment for ADHD inattentive type and a cross-sectional study examined the impact of the group size on task behavior and work productivity in children with ADHD. Results: The findings indicate that the interventions used in all four studies could lead to increased satisfaction among participants and parents, as well as a reduction in problem behavior. In terms of the research indicators, the RCT had low quality, while the others were of high quality. Conclusion: A larger number of studies and the ADHD clinical population would help to increase the generalizability of future reviews of treatments in this context.

Naveena Kumara K. T.,Singh Harminder,Kaur Nirmaljit,Kang B. K.,Devi Indira 한국원예학회 2023 Horticulture, Environment, and Biotechnology Vol.64 No.5

The present study was aimed to assess the effi cacy of foliar-applied uniconazole on fl ower induction, and fruit yield of mango cv. ‘Dusehri’ at Department of Fruit Science, Punjab Agricultural University, Ludhiana, India. The experiment was conducted simultaneously at two diff erent locations, for two cropping seasons during 2019–20 (ON year) and 2020–21 (OFF year). The pre-fl owering treatments of paclobutrazol and uniconazole were sprayed during September and October at diff erent rates. Experimental plants were observed for various biochemical, vegetative, reproductive and yield parameters. According to the results, foliar application of uniconazole (T6) @ 1.0 g a.i/m canopy applied twice signifi cantly enhanced chlorophyll, carbohydrates, and C:N ratio and negatively aff ected shoot growth, nitrogen content by inhibiting the gibberellin biosynthesis. Ultimately, uniconazole improved fl owering, fruit retention, fruit yield, and fruit size in mango cv. ‘Dusehri’. Therefore, the foliar application of uniconazole can be considered as a better alternative to paclobutrazol in fl ower induction of mango.

Heatwaves are acknowledged to be the major meteorological disaster, causing a noticeable impact on humans and animals’ lives during the last few decades. The number, frequency, duration, intensity, and areal extent of the heatwaves are on the rise during recent years. The Maximum temperature data of 2013 is analyzed to assess the synoptic nature, intensity, frequency, and various significant facets of the heatwave over the south peninsular states of Andhra Pradesh and Telangana. Indian subcontinent experienced a major heatwave during 2013, which claimed 1216 human lives. Even though the highest intensity of maximum temperatures is observed in May over major areas of India, the increasing (incidence, duration, number of spells, and the sweltering temperatures) number of heatwaves are observed over many parts of the country. The northwest and southeast coastal regions are the two heat wave prone regions. The advection of heat from the northwest with the aid of north-westerly winds causes heatwaves over northwest India to sweep or move towards India’s southeast and east coast. The heatwave record over south-eastern India, i.e, Andhra Pradesh and the adjoining Telangana state during May 22-24, 2013 were described in this study. Maximum temperatures above 40°C are observed with a sudden rise by 6 to 7°C over the study region. An attempt is made to predict the maximum temperatures 72 hours before the existence of a heatwave at 3 km horizontal resolution using the Advanced core of the Weather Research and Forecasting (WRF) model. Model predicted temperature values match with observations and the statistical metrics show a high index of the agreement, lower values for root-mean-square error and mean absolute error. Atmospheric circulation patterns associated with this heatwave are also presented. The arrest of sea breeze, the hovering of diabatic heat because of subsidence is the factor that abetted the heatwave blockade over the south-eastern part of the country. The WRF model forecasts could present the occurance of the heat wave over AP and Telangana region with 72 hour lead time with high accuracy.

Nadur L. Naveena,Suryanarayana Subramanya,Siddappa Setty,V. Palanimuthu 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.2

The forest dwelling tribal Soligas who reside at Biligirirangana Hills cultivate more than 30 different crops including pulses, cereals, millets and vegetable crops as a part of subsistence agriculture. They store more than 80% of their produce in their households for consumption. The present study examines the grain storage practices followed by Soligas and the extent of losses incurred by them, in a traditional agricultural setup. In all, 13 different storage structures used by Soligas were recorded. These included both traditional and modern structures. Among these, plastic oven sac was being used most widely, while Thenemane used for storing maize cobs was the least used structure by the Soligas. An evaluation of these storage structures for safe storage of grains revealed that, none of the traditional storage structures were found to be suitable for grain storage, as they had one or the other disadvantages like, not being moisture or insect or rodent proof. However, the modern structures like, the plastic bins were moisture and rodent proof, but they failed to provide protection against insects. Soligas adopted 10 different grain protection methods for safe storage of grains. Despite their use, the presence of insect infestation ranged from 32.14 to 56.41%. Callosobruchus theobromae was the most common stored grain insect found infesting fieldbean (Dolichos bean) that was stored in most of the settlements, while Tribolium castaneum was the rarest, found infesting only split pigeon pea (Cajanus cajana). The extent of grain damage ranged from 10 to 100% in the samples collected.

Technological demands of meat processing-An Asian perspective

Zhang, W.,Naveena, B.M.,Jo, C.,Sakata, R.,Zhou, G.,Banerjee, R.,Nishiumi, T. Applied Science Publishers 2017 Meat science Vol.132 No.-

<P>A rapid increase in the economy, population, industrialization, and urbanization of Asian countries has driven the fast development of their meat industries over recent decades. This consistent increase in meat production and consumption in Asia has been the major cause for the development of the global meat industry. Meat production methods and consumption are very diverse across different regions and countries in Asia, and thus, it is impossible to cover the technological demands of all Asian countries in this review. Here, we have mainly highlighted the differences in meat production methods and consumption in Asia during recent decades and the meat technology demands of three east Asian countries, namely China, Korea, and Japan, and one south Asian country, India. A brief introduction of the meat industry, in particular the production and consumption trend in these countries, is provided in this article. The technology demands for fresh and processed meat products are then reviewed.</P>

K. Srinivasa Rao,P. Naveena,K. Girija Sravani 한국전기전자재료학회 2019 Transactions on Electrical and Electronic Material Vol.20 No.4

In this paper, we have enhanced the performance of the existing switch operating at 35 GHz by using a novel optimization process and these results are compared with the existing experimental results. The same optimization process is utilized to design the switch at 5G mobile communication frequencies (38 GHz) and its performance is analyzed. The switch is designed on the coplanar waveguide having 50 Ω impedance matching and is optimized based on the wireless application system for Ka-band (27–40 GHz) at a resonance frequency of 38 GHz. The proposed switch at 38 GHz exhibits low input reflection coefficient (S 11 ) of 13.86 dB (> 10 dB), low insertion loss (S 12 ) of 0.44 dB (< 1 dB) and high isolation (S 21 ) of 33 dB at Ka-band frequencies. The proposed structure is designed to have less spring constant of 2.38 N/m and actuation voltage of 11.97 V. During UP state position switch develops an ON-state capacitance of 31 fF and OFF state capacitance of 0.152 pF during downstate with a capacitance ratio of 4.90. The switch requires low switching time of 0.19 ms and it can withstand up to the force of 12.97 × 10 −4 N which is generated during actuation. Thus, the proposed switch can be eff ectively optimized for good performance and can be used for high-frequency 5G communication applications.

Kumaresan Poorna Chandran,Prabu Poorna Chandran,Naveena Arumugam,Sendhilkumar Muthappan 사단법인약침학회 2021 Journal of Acupuncture & Meridian Studies Vol.14 No.1

Background: Periarthritis of shoulder is a painful condition of the shoulder, affecting 2-3% of the general population and 20% of diabetic patients. Acupuncture is a widely practiced traditional Chinese medicine. Recent evidence shows that it alleviates shoulder pain with different needling techniques. Objectives: The present study is to compare the efficacy of remote and local points on PAS. Methods: 60 subjects were randomly assigned into two groups, remote acupuncture group (n = 30) and local acupuncture group (n = 30). Both groups were assessed at baseline and at the end of 12 sessions. Shoulder pain and its disability index (SPADI) and (ROM) were measured using goniometer. The intervention was given weekly thrice on alternate days for four weeks with 20 min for each session. Results: The result shows that both remote and local acupuncture points were beneficial in the pain management and rage of motion when compared within the group. The effects of acupuncture at remote acupoints were better than those at local acupoints in SPADI and ROM when compared between two groups. Conclusion: In treatment of periarthritis of shoulder remote acupuncture points may have higher therapeutic value when compared to local points.

Adult emergence pattern and utilization of females as attractants for trapping males of white grubs, Leucopholis lepidophora (Coleoptera: Scarabaeidae), infesting areca nut in India

C.M. Kalleshwaraswamy,S.K. Adarsha,N.L. Naveena,Sharanabasappa 한국응용곤충학회 2016 Journal of Asia-Pacific Entomology Vol.19 No.1

White grub, Leucopholis lepidophora Blanchard (Coleoptera: Scarabaeidae: Melolonthinae), is a major insect pest infesting areca nut in India. Larvae feed on roots (hence also called root grubs), causing reduced number of roots, loss of anchorage, stem tapering, reduced number of fronds, yellowing of leaves, yield reduction and death of the plants. The biology and ecology aspect of this scarabaeid are scanty. Hence, the aim of this study was to understand the ecological and behavioral aspects to develop IPM program. The adult emergence pattern of L. lepidophora was observed daily during the rainy season. The emergence period was defined between June and October during 2013 and 2014. Peak emergence of adult beetles occurred between 1900 and 2000 h. When raining occurred between 1800 and 2100 h, no emergence of adult beetles was observed. The sex ratio of L. lepidophora varied over time, but the overall sex ratio was female biased in both the study years (female:male; 1:1.18 and 1:1.46 in 2013 and 2014, respectively). Males were found to emerge first in the season resulting in protandry. Innovative idea emerged during our field experiments in 2013–2014 was the use of female beetles for attracting male beetles. Female adults were collected and placed individually in traps made of small pouches of nylon net and were tied to the areca palm at a height of 5 ft. Trap containing a female beetle attracted male individuals for about 8–10 days. The same technique was employed for the large-scale collection of beetles during 2014. A total of 1843 males were collected in an areca grower's field using female-baited traps during 2014. Male baited traps did not attract female beetles, indicating existence of only female produced semiochemical that attracts males. Our findings provide new insights for incorporating adult collection using female- baited traps in IPM against areca nut white grubs.
