Not all individuals respond identically, or at times in the same direction, to dietary interventions. These inconsistencies likely arise because of diet and genomic interactions (nutrigenomics effects). A host of factors may influence the response to bioactive food components including specific polymorphisms (nutrigenetic effect), DNA methylation patterns and other epigenomic factors (nutritional epigenomic effects), capacity to induce anuo. suppress specific mRNA expression and patterns (nutritional transcriptomics), the occurrence and activity of proteins (proteomic effects), and/or the dose and temporal changes in cellular small molecular weight compounds will not only provide clues about specificity in response to food components, but assist in the identification of surrogate tissues and biomarkers that can predict a response. While this 'discovery' phase is critical for defining mechanisms and targets, and thus those who will benefit most from intervention, its true usefulness depends on moving this understanding into 'development' (interventions for better prevention, detection, diagnosis, and treatment) and a 'delivery' phase where information is provided to those most in need. It is incumbent on those involved with food and nutrition to embrace the 'omics' that relate to nutrition when considering not only the nutritional value of foods and their food components, but also when addressing acceptability and safety. The future of 'Nutrigenomics and Health Promotion' depends on the ability of the scientific community to identity appropriate biomarkers and susceptibility variants, effective communications about the merits of such undertakings with the health care community and with consumers, and doing all of this within a responsible bioethical framework.

The Purpose of this study was to reveal the biomechanical difference of two soccer footwear(soft ground footwear and hard ground footwear). Secondly, the purpose of this study was to clarify how each type of soccer footwear effects soccer players, which will provide scientific data to coaches and players, to further prevent injuries and to improve each players capacity. The result of comparative analysis of two soccer footwear can be summarized as below. The comparison of the very first braking force at walking found distinctive factors in the statistical data(t=3.092, p<.05). Braking impulse of two difference footwear showed distinctive factors in the statistical data(t=2.542, p<.05). In comparing GRFz max(N), the result showed a statistically significant difference in the two soccer footwear at running(t=2.784, p<.05). In the maximum braking impulse(t=2.774, p<.05) and propulsive impulse for antero-posterior direction, there was a statistically significant difference between the two soccer footwear at running. In the maximum braking force(t=3.270, p<.05) and propulsive force(t=4.956, p<.05) for antero-posterior direction, there was a statistically significant difference between the two soccer footwear at running. Significant differences were not found in moment(rotational friction) with two difference soccer footwear(moment max; t=2.231, moment min; t=1.784).

This article is based on the findings of problems and limits in implementing integrated coastal management strategy in Shihwa Lake area to develop management framework, mechanisms and processes that insure the participation of various stakeholders in making decisions for sustainable development of reclaimed land. The project performance of the Shihwa Comprehensive Management Plan for Water Quality and Environment Restoration formulated in 2001 was evaluated and reviewed to give some valuable guidance for reducing the wide gap between integrated planning and implementation. Managing inter-sectoral conflicts among future land uses in Shihwa reclaimed area is one of the most important issues to make progress in integrated coastal management. There is a urgent need of developing scientific decision-supporting tools for evaluating the alternative scenarios as well as capacity building programs for local stakeholders.

Coronavirus is generally known to cause minor respiratory diseases in animals and humans. However, some coronavirus genus is reported to cause animal-to-human interspecies infection. Since the end of 2019, a new type of coronavirus (COVID-19) infection is spreading rapidly throughout the world, leading to the declaration of the pandemic by the World Health Organization (WHO). Despite various clinical studies to counter COVID-19 infection, the total confirmed cases and death rates are still accumulating. To break down this new threat, we should pay attention to newly revealed information based on scientific facts. In this review, we introduced the clinical characteristics, diagnostic methods, and treatment of patients infected with COVID-19. Moreover, we highlighted the correlation between COVID-19 severity and patients with underlying diseases. Potential risks associated with COVID-19 can be differed depending on the condition of patients and can cause pulmonary complications. Therefore, lung capacity exams are expected to help predict the progression of the disease along with previously established detection methods such as molecular diagnostics and immunoassay. Although physiological research hasn't yet been emphasized to evaluate COVID-19 infection, this review is expected to be valuable to give new inspiration to deal with COVID-19 which might strike again in the future.

Since sewer rehabilitation program requires long construction period and enormous capital investment, determination of rehabilitation priorities is important with systematic planning considering appropriate evaluation parameters. In this research, we applied PROMETHEE(Preference Ranking Organization METHod for Evaluations) known as very objective and scientific multi-criteria decision-making analysis, using the weights determined by AHP(Analytic Hierarchy Process) for the selected sewer evaluation items to calculate the rehabilitation priorities for each sewer sub-catchment in basin Gusan 1 of Seoul. Preference functions and preference thresholds were estimated for each criterion of ratio of lack of hydraulic capacity of sewers, defect ratio, ratio of sewers with velocity less than its minimum criteria, and density of sewers in the sub-catchment. As a result, it was found that region d had the first priority among four sub-catchments. For each and every sewer located in region d, we could also rank sewers to be rehabilitated urgently.

Robinia pseudoacacia is one of most widely cultivated exotic species in Bulgaria. The total area of black locust plantations amounts to 2.9% of the total forest area of the country. 15.34% of the plantations are of management afforestations category, where the priority is given to timber production. They have been created on rich and moisture soils, which are the most appropriate for the species in order to achieve its biological potentials of high productivity. The rest of the available plantations in the country are planted on poorer and drier soils up to 600~800 m altitude. The high adaptive ability of the species to unsuitable environmental conditions as well as the high sprout potential was used for their creation. These stands are mainly done with the aim to protect and ameliorate damaged environments and production of small-size timber and fire woods. They are cultivated until 15-20 years and are revived by sprouts. Therefore the management goals searched, 45.69% of those forests are low productive and 38.97% with average productiveness. The present report deals with growth and productivity capacity of black locust plantations; production of sowing materials; production of reproductive and vegetative saplings for afforestation; the technological aspects of afforestation works; the management and use of black locust plantations as well as some more important diseases and pests affecting the species. The report is entirely based on Bulgarian scientific research works and experience with the Robinia preudoacacia. Recommendations for optimizing the use of species are given.
