Patients' health data is very sensitive and the access to individual's health data should be strictly restricted. However, many data consumers may need to use the aggregated health data. For example, the insurance companies needs to use this data to setup the premium level for health insurances. Therefore, privacy-preserving data aggregation solutions for health data have both theoretical importance and application potentials. In this paper, we propose a privacy-preserving health data aggregation scheme using differential privacy. In our scheme, patients' health data are aggregated by the local healthcare center before it is used by data comsumers, and this prevents individual's data from being leaked. Moreover, compared with the existing schemes in the literature, our work enjoys two additional benefits: 1) it not only resists many well known attacks in the open wireless networks, but also achieves the resilience against the human-factor-aware differential aggregation attack; 2) no trusted third party is employed in our proposed scheme, hence it achieves the robustness property and it does not suffer the single point failure problem.

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.

This study was conducted to approach the Korean new food words for the years 1994-2005 from the stance of food ethics. The new food words were categorized into food industry, foodstuffs, cooking, various foods, processed foods, distribution, and consumer health. The principles of food ethics applied to new food words include a respect for life, justice, environmental preservation, priority of safety, and dynamic equilibrium. Seventy percent of new food words were ethically neutral, while 30% had significant ethical meaning. There were more words with a negative ethical meaning than with a positive one. All of the principles, except respect for life, could be successfully applied to new food words. Dynamic equilibrium was the most appropriate principle for the new food words, followed by a priority for safety, justice, and environmental preservation. The results of this study implied that moderation and balance is required in our modern dietary life.

Garlic is an important condimental vegetable which has many minerals and numerous organic sulfur compounds. Owing to these components, garlic has many medicinal properties and physiological activities on human health. It can lower sect lipid levels and reduce the severity of cholesterol-induced atherosclerosis. And it appeals to protect against mutagenic and carcinogenic effects. Today's our eating habit is concentrated on the physiological function in floods rather than their taste or mutagenic. To improve garlic's value as a flood or a vegetable, further scientific researches about its volatile and nonvolatile sulfur compounds through the biochemical approach are needed. In addition to that, both areas that the development of garlic-processed goods and utilization of garlic as materials for medicine must be actively studied.

Amended Water Quality Environment Preservation Law enacted that the areas where nonpoint pollution is serious can be designated as Nonpoint Source Management Region. According to Section 54 of Water Quality Environment Preservation Law, corresponding watersheds are areas where runoff from nonpoint pollution source may deteriorate river and lake water quality, residents' health and property, and ecosystem. The criteria are as followings; i) where nonpoint source contribution result in or will result in significant ecological destruction, iii) national or local industrial complexes and cities having population greater than one million where nonpoint source managements are necessary, iv) where specific measurement is necessary because of its geological and stratigraphic characteristics. In this research, detailed designation criteria was developed reflecting current nonpoint source management situation and its discharge characteristics. Depending on the result, target regions were also suggested. In additions, it will be desirable that the target regions are prioritized considering institutional execution availability, stakeholder's agreement, and connection with existing nonpoint source pollution management measures.

This study was carried out to find the problems of assessment on terrestrial ecosystem part in environmental impact analysis(EIA) and to suggest the proper amelioration measures by analyzing 19 environmental impact statements(EIS) published during the period from 1991 to 1994. The results obtained from this study were as follows. Field survey for the investigation of fauna and flora in project areas should be conducted at least 3 times a year and name of investigator should be written on the EIS clearly. Increase or decrease in degree of green naturality and productivity cannot be an absolute criteria for expressing the amount of changes in ecosystem. Evaluation for the ecosystems and their composition in project area is more important than presenting merely the increase or decrease in degree of green naturality and productivity. Alleviation measures in 19 EISs analyzed in this study were summarized into 6 types: They are establishment of landscape plan, transplanting of useful trees preservation of big tree and protected species, restoration and preservation of existent vegetation, establishment of soil conservation measures and diminution of the impact on animal. However, they were somewhat insufficient because they wouldn't suggest the alleviation measures in detail. The more positive counter-proposals are needed to decrease the impact of the project on terrestrial ecosystem.
