The Post Baccalaureate in Teacher Education Program of the Polytechnic University of the Philippines which is also offered in its Bataan Branch is a one-year degree course enabling non-education graduates to take the Licensure Examination for Teachers after its completion, thus giving them the option to shift to the teaching profession. Prior to the conferment of the degree, students are required to pass all the requirements of the curriculum including the Practice Teaching on their last term. Their undergraduate course is considered their major or specialization. Since the subject of the study was second coursers who were either employed or self-employed, and majority was married, they were often heard to complain of stress particularly when they were already engaged in Practice Teaching. The investigation was conceived to find out what were the stressors of the 36 respondents who were enrolled in the program during the Second Semester of School Year (SY) 2010-2011 and SY 2011-2012 respectively and what actually caused their stress so that Teacher Training Institutions can provide the future enrollees of the same program with learning environment and interventions that will provide their students with better learning experiences. The descriptive research method was utilized by the researcher to present the phenomenon. The direction of the research was taken from the works of Clemant (1999), Corcoran (1989), Hemmings and Hockley (2002); Hunter Boykin and Thompson (1993); Piggie and Marso (1998);Schwab (1989); Wadlington, Slaton Partride (1998) and Mee (2009) who examined stress among teacher candidates during the field experience and found it to be a significant issue. There was an agreement on the cited works of these scholars that stress levels were generally high during student teaching. However, in the seven-year study conducted by Piggie and Marso (1998) they found out that teacher candidate’s anxiety decreases as they progress through the teacher preparation program. This was supported by Fives, Ham man, and Olivares (2007) who maintained that the teacher candidates, who experienced high guidance through the levels of support from the education institutions, demonstrated lower levels of burn out at the end of their practicum than candidates with low guidance. Therefore, the study was conducted to find out if similar findings can be drawn from the questionnaire-checklist treated both qualitatively and quantitatively.

Preterm birth is defined as childbirth occurring at less than 37 completed weeks or 259 days of gestation. Preterm birth is a global problem and evidently more than 60 % of preterm births occur in Africa and South Asia. In India preterm births is rising and presently around 21 % of babies were born preterm. Neonatal intensive care unit stimuli may interfere with brain development in premature infants and contribute to developmental delays. Statement of the Problem: A Quasi Experimental Study to Assess the Effectiveness of Sensory Nursing Interventions on Feeding Progression among Preterm Infants in Selected Setting, Nagercoil, K. K District. A Quantitative Research Approach- Quasi experimental research design was adopted. The study was conducted on 125 each on study and control group. The investigator provided Sensory Nursing Intervention care on study group preterm infants along with routine hospital and control group was obtaining routine hospital care. Both the group were assessed with Preterm Infant Breast feeding Behaviour scale. The study concludes that the mean feeding progression of the control group was 6.1± 1.5 on pretest to post test assessment was also improved as 17.0± 1.7 without sensory nursing intervention. The mean feeding progression of pretest to posttest assessment of the study group was 5.3±1.1 and improvement after sensory nursing intervention was 19.8± 0.6.

Rapid Urbanization and growing consumer’s concern for food safety, health and environment in recent times has resulted in a new tide in consumption of organic foods especially Organic Tea. Many recent researches have studied about the awareness and consumption pattern of Organic Foods and concluded that it is significantly higher in developed countries than developing ones. In countries like India, where organic food markets are still in the nascent phase of its growth, the level of awareness and acceptance is relatively low. The present study aims at analyzing factors effecting consumer awareness levels and buying perception regarding Organic Tea with the help of an Exploratory study using a structured survey of 200 respondents in Delhi-NCR through pre-tested Questionnaires using convenience sampling. This paper attempts to investigate the demand status of Organic Tulsi Tea as people residing in urban areas like Delhi-NCR as they are more conscious about their health and lifestyle and maximum of them are working professionals. The Consumers in Metro cities have a good purchasing power to pay premium prices for organic products so they prefer to include organic teas & supplements for a healthy lifestyle.

The present study was undertaken to isolate, determine the inhibitory profile against shrimp test pathogens and identify the actinomycete isolates with prominent activity. A total of 47 Actinomycetes were isolated from 45 samples which included seawater, marine sediment and swab samples of submerged substrates from the Mangrove swamp area located along the coast of Thoothukkudi, Tamil Nadu, India. High number of actinomycetes were isolated from the mangrove sediment samples (26) followed by swabs (12) and seawater (9). 34 (72%) actinomycetes exhibited antagonism to the shrimp test pathogens, Vibrio alginolytics, V. harveyi, and V. parahaemolyticus to varying degrees. 12 isolates exhibited prominent inhibitory activity against the shrimp test pathogens. The isolate A10 displayed maximum inhibitory activity, with ≥ 20 mm, zone of growth inhibition against all the three shrimp test pathogens. In the color series, high number of antagonistic actinomycetes belonged to gray color series (21) followed by white color series (7) and violet color series (1). The antagonistic actinomycete isolate A10 exhibited prominent inhibitory activity against all the shrimp test pathogens and hence was subjected to standard chemotaxonomic and light microscopy investigations and was identified to be belonging to the genus Streptomyces spp. The results of the present study indicate that, Mangrove swamp areas are one of the good sources of inhibitory marine actinomycetes. Also, because these isolates displayed antagonism against the shrimp pathogens, they could be used as bio-control agents in shrimp aquaculture systems for preventing the outbreak of shrimp diseases caused by bacterial shrimp pathogens such as Vibrio alginolyticus, V. harveyi and V. parahaemolyticus. Also, novel, anti-microbial compounds can be extracted from these inhibitory marine actinomycetes for controlling shrimp diseases caused by the antibiotic resistant shrimp bacterial pathogens

Simarouba Glauca is an agro climatic plant having wide range of economical importance and new generation biofuel source, but it has a very small population in India. In order to increase its number it is necessary to propagate this plant through in vitro regeneration methods. Woody plants generally contains high amount of secondary metabolites and phenolic substances which inhibits the regeneration. Frequent sub culturing and incubation in dark are the simplest methods to reduce the browning effect up to some extent, but use of HgCl2 showed higher rate of survival of the explants. Various concentrations of Mercuric Chloride have been used in this study. Pre- treatment of 2.5% Ascorbic acid along with the 0.1% HgCl2 treatment for 2-3 minutes gave the effective results.

The present study thus focuses on water management strategy carried out in the Indian city of Bhopal whose, surging topography is spotted with a big quantity of large number lentic water bodies. Presently, the city is at risk, and requires urgent implementation of an integrated urban water management system. To understand the existing scenario of the water management system carried out by both government and other responsible bodies, quantitative analysis has been sought based on survey mode of data collection carried out on 5000 residents residing in the Kolar Road and Old Bhopal of the capital city. The role of various stakeholders in water management in Bhopal is satisfactory in certain areas but adequate improvement in needed– such as, lack of awareness among residents in prevention of water wastage, lack of initiatives adapted by NGOs and civil agencies to educate the residents in managing water and thereby preventing its wastage. There is need to strengthen its technological innovation. Also, private partnerships should be encouraged, along with more stringent government laws. Private water suppliers need to act more responsibly while distributing water. More effective participation of the NGOs in educating the masses of water management practices thereby developing the present loopholes is recommended.
