In the present highly changing era, every dimension from Technology to Education, Environment to Sanitation and from Agriculture to our Food basket is getting changed. Our experiences say that the most affected ethnic group from this rapidly changing pattern of our food intake, lifestyle are our adolescent. This is also a fact that our adolescent passes their 2/3 of time of a day in their schools. In this regard our school system needs to formulate their comprehensive approach to Health for our adolescents. On other hand Ayurveda, the ancient Indian system of Medicine had expressed views on a concept of Holistic Health thousand years ago. This research article is an attempt of borrowing this valuable concept from Ayurveda and suggesting to introduce them into our comprehensive school health programme such as concept of wellness, quality of life, Holistic Health and measures related to diet and lifestyle for preservation, promotion of health and prevention of disorders etc. This manuscript also evaluates the existing approaches of school health programmes towards current scenario. Now a day's our food habits, dietary intake and the life style are not at the level of satisfactory condition this lead to early onset of metabolic chronic disorder especially in our adolescents because on the basis of age-immunity relationship they are easily targeted. The chronic metabolic disorders results into overweight, obesity, anxiety, mental trauma, distress, over- fatigued, incapable for physical work, getting tired soon. This article provides a space to rethink and reformulate our school health programmes in light of our ancient tradition of medicine.

As this study was estimation of factors of rapid OUR (Oxygen Uptake Rate) monitoring method. Experiment for estimating factors of optimal microorganism activity was carried out in this study. In addition to comparison and estimation of SCOD variation by OUR variation using real wastewaters. In consequence OUR value was highest when F/M ratio, pH and temperature were 0.03~0.05, 6.0~8.5 and $20{\sim}30^{\circ}C$ respectively. Oxygen consumption by nitrification was incomplete. OUR variation of SCOD was recognizable difference of degradable rate at before and after of inflection point OUR. This study used an experimental method for real time prediction of the influent of the sewage treatment plant for optimal operation is expected to be able to do.

The governance structure of corporate is very important to raise the nation's economic efficiency and the operation result of firm. However, the innovation of corporate governance structure is a important problem to improve international confidence in our country, since most large corporate in our country has a promodern governance structure to be influenced in decision making of corporate group by minority governance-shareholder. Therefore, in our country the improvement of corporate governance structure is very urgent. This study examine the improvement device of corporate governance structure to be introduced in our country, and present the improvement direction to be suitable to our country's economic circumstance.

Oxygen uptake rate (OUR) was used as an indicator of microbial activity. In this study OUR at dyeing wastewater in the pilot plant was monitored to examine biological activity. Correlation between inlet COD concentration and maximum OUR showed that maximum OUR was proportional to inlet COD concentration. Changes in the OUR values reflected the changing waste load in the reactor. Consequently, OUR can be used to estimate biological activity of inlet COD concentration. This study showed that biodegradable COD at dyeing wastewater could be calculated from OUR and yield coefficient. Non-biodegradable COD was able to be calculated from a difference between initial COD concentration and biodegradable COD.

A simple but accurate analytical model for the lateral channel electric field in gate-offset structured Lightly Doped Drain MOSFET has been developed. Our model assumes Gaussian doping profile, rather than simple uniform doping, for the lightly doped region and our model can be applied to LDD structures where the junction depth of LDD is not identical to the heavily doped drain. The validity of our model has been proved by comparing our analytical results with two dimensional device simulations. Due to its simplicity, our model gives a better understanding of the mechanisms involved in reducing the electric field in the LDD MOSFET. The model shows clearly the dependencies of the lateral channel electric field on the drain and gate bias conditions and process, design parameters. Advantages of our analytical model over costly 2-D device simulations is to identify the effects of various parameters, such as oxide thickness, junction depth, gate/drain bias, the length and doping concentration of the lightly doped region, on the peak electric field that causes hot-electron pohenomena, individually. Our model can also find the optimum doping concentration of LDD which minimizes the peak electric field and hot-electron effects.

A critical discussion of our knowledge about extragalactic cosmic rays and magnetic fields is at-tempted. What do we know for sure? What are our prejudices? How do we confront our models with the observations? How can we assess the uncertainties in our modeling and in our observations? Unfortunately, perfect answers to these questions can not be given. Instead, I describe efforts I am involved in to gain reliable information about relativistic particles and magnetic fields in extragalactic space.

In 2015, Korea won the first place among 30 countries in Open, Useful, and Reusable (OUR) Data Index, which is an OECD's open government data indicator. On the other hand, Korea was ranked the 17th among 86 countries in Open Data Barometer (ODB) of World Wide Web Foundation. In this study, the research subject comes from two reasonable academic doubts on why the gap is wide between the two indicators of Korea and whether the OUR Data Index made proper evaluation on Korea's open government data. Based on the assumption that there may be some critical points in the measuring method of OUR Data Index, the study conducted a comparison of the two indicators. The result found that first, the two indicators almost had no correlation to each other; second, OUR Data Index had a more vague evaluation framework as well as less amount of government data for evaluation than ODB; third, while the government support takes a significant share in the OUR Data Index, it is considered as a mere input element; and fourth, the OUR Data Index does not evaluate the impact of open government data, whereas ODB includes the impact of open data on the government, economy, and society.

Exploring on two major questions: 'Why do we feel more love for certain objects?' and 'How can design use this knowledge to realize design sustainability?', this article presents an alternative way of approaching the problem of design sustainability from the perspective that our relationships with design objects are of an extended mode of social relations. Recent discussions on design sustainability have transformed the notion of the problem by seeing it as a problem of our basic perception of design objects and our relationships with them. In this light, I propose that design sustainability could not be achieved solely by approaching from a mechanistic perspective, but by re-framing the way we see and relate things around us and by supporting our changes and actions to move forward a more sustainable notion of our relationships with the objects. As a way to realize design sustainability, I propose that design should involve story-making quality that supports our initiatives to build more affectional relations with objects by seeing the objects as entities of communication that tell stories of us, thus reflect our identities and meanings of our lives. Proceeding on the exploration of the subject, I present some of conceptual outlines in forms of an image diary, an interplay-able furniture unit, and a performance instruction that suggest a way for a special story-making process and thus a stronger emotional tie with the objects.

This paper examines the relationship between investor sentiment and the risk of a stock price crash at the firm level. Our dataset includes 131 firms listed on the Saudi stock exchange (Tadawul) from 2011 to 2019, as well as 953 firm-year observations. To evaluate crash risk, we employ two distinct proxies and propose an index for measuring firm-level sentiment which we use for the first time in our study. The average turnover rate, price-earnings ratio, and overnight return are the three sentiment proxies we utilize in our index. Our findings show that high levels of investor emotion increase managers' proclivity to withhold unfavorable news from investors, which aggravates the risk of a stock price crash. We undertake cross-sectional regressions by sector to ensure the robustness of our findings, and our findings are confirmed. After accounting for any endogeneity issues with the GMM technique, the results remain the same. Furthermore, we analyze the liquidity effect by dividing our sample into subsamples with better and worse liquidity and find that firms with worse liquidity have a considerably greater positive impact of investor mood. Overall, our findings help investors and regulators recognize the significance of this downside risk and how to manage it in the stock market.
