Background: Work-related stress is one of the major causes of occupational ill health. In line with the regulatory framework on occupational health and safety (OSH), adequate models for assessing and managing risk need to be identified so as to minimize the impact of this stress not only on workers' health, but also on productivity. Methods: After close analysis of the Italian and European reference regulatory framework and workrelated stress assessment and management models used in some European countries, we adopted the UK Health and Safety Executive's (HSE) Management Standards (MS) approach, adapting it to the Italian context in order to provide a suitable methodological proposal for Italy. Results: We have developed a work-related stress risk assessment strategy, meeting regulatory requirements, now available on a specific web platform that includes software, tutorials, and other tools to assist companies in their assessments. Conclusion: This methodological proposal is new on the Italian work-related stress risk assessment scene. Besides providing an evaluation approach using scientifically validated instruments, it ensures the active participation of occupational health professionals in each company. The assessment tools provided enable companies not only to comply with the law, but also to contribute to a database for monitoring and assessment and give access to a reserved area for data analysis and comparisons.

In this study, geomorphological and geological research has been carried out to estimate the possibility of ancient port location near Hwaseong Dangseong. Geomorphological characteristics around Eunsupo were analyzed through comparison of past and present topographic maps and field survey. Grain size, age dating, and geochemical analysis on surface sediments and borehole sediments were performed. Through the geomorphological characteristics analysis, it was interpreted that Eunsupo area was submerged in seawater especially at high tide in the past, and that ships could approach to the inside of the area through the tidal channel which were developed in the area. It is also assumed that ships were anchored at a low elevation point in the area. The paleo-environmental change in the area was analyzed based on the classification of sedimentary environment using grain size distribution of surface and borehole sediments and geochemical analysis. It was confirmed that the geomorphological interpretation for the possibility of ancient port location coincided well with the paleo-environmental change interpreted through sediment analysis. This study is a basic study for estimating ancient port location, and it is expected that more accurate paleo-environmental changes will be restored through detailed geomorphological survey and additional borehole analysis in the future research.

2-D wavelet analysis is applied to bathymetric data from the KR1 area of Korea Deepsea Mining Area. The wavelet analysis is one of the quantitative methods to analyze the topography. The wavelet allows us to create filters to select for topography in a continuous variety of shapes, sizes, and orientation. The 2-D Linear B-spline filter, 100 BS and 100 NF, is convolved with bathymetric data to identify the location of abyssal hills and abyssal troughs in bathymetry. In addition, the 2-D derivative of Cubic B-spline filter, 60 BS and 60 NF, is applied to bathymetric data to find the slope of abyssal hill in bathymetry. These filters were rotated $5^{\circ}$ counterclockwise from NS to match the dominant orientation of seafloor lineament. Both filters result in good match with abyssal hills, troughs, and slopes. This method can apply to fault, fold, and other lineament structures description with variable size. The result of application shows that wavelet analysis of bathymetric data could be used with fundamental data of geophysical analysis.

Currently in Korea, Researches on universal design have been actively accomplished in various fields as not only housing and public space, but also product design and education. The purpose of this study is to analyze previous researches on universal design and to identify its research trends which might suggest the future directions of the related studies. In this study, researches on universal design were analyzed to classify the types according to research area, objects and respondents. Two hundreds twenty one papers(journal articles, theses, dissertations, etc.) which were published in Korea from 1997 to 2008 were analyzed. The results were as follows. Researches on universal design have increased quantitatively and research topics have been diverse. In the 1990s, with the introduction of universal design concept, research area focused on space design, but since 2000 researches on universal design have been expanded to apply the fashion, product design and education. In terms of research objects, the studies about evaluation and case analysis have conducted more than those about principles and planning design. With regard to research respondent, the studies for the elderly or people with disabilities and those of all people including a specific target have conducted in a similar ratio. Previous studies were contributed to expand the topics of universal design and it is time to study the applications based on previous research results for utilization and dissemination of universal design. Also it is necessary to conduct interdisciplinary studies in the field of universal design.

The diversity elucidation by amplified ribosomal DNA restriction analysis and 16S rDNA sequencing of 96 associative diazotrophs, isolated from the feeder roots of tea on enriched nitrogen-free semisolid media, revealed the predominance of Gram-positive over Gram-negative bacteria within the Kangra valley in Himachal Pradesh, India. The Gram-positive bacteria observed belong to two taxonomic groupings; Firmicutes, including the genera Bacillus and Paenibacillus; and Actinobacteria, represented by the genus Microbacterium. The Gram-negative bacteria included ${\alpha}$-Proteobacteria genera Brevundimonas, Rhizobium, and Mesorhizobium; ${\gamma}$-Proteobacteria genera Pseudomonas and Stenotrophomonas; and ${\beta}$-Proteobacteria genera Azospira, Burkholderia, Delftia, Herbaspirillum and Ralstonia. The low level of similarity of two isolates, with the type strains Paenibacillus xinjiangensis and Mesorhizobium albiziae, suggests the possibility of raising species novum. The bacterial strains of different phylogenetic groups exhibited distinct carbon-source utilization patterns and fatty acid methyl ester profiles. The strains differed in their nitrogenase activities with relatively high activity seen in the Gramnegative strains exhibiting the highest similarity to Azospira oryzae, Delftia lacustris and Herbaspirillum huttiense.

In this study, we tried to quantify the actual cross-sectional area inside the bore when scanning by the MRI system with various bore sizes. To this end, a comparative analysis was conducted by both of blueprint of each MRI equipment and actual measurement in the field. As a result of analysis, ACSA(Actual Cross-Sectional Area) in Ingenia CX, Elition X, uMR 780, Omega, Vida, Lumina, Architect, Premier is recorded as 171230, 232150, 242100, 309332, 230760, 230760, 229380 and 235990 ㎟, respectively ACSA% was 60.6, 60.3, 73.0, 70.0, 60.0, 60.0, 59.6, and 61,3%. In addition, DTB (Distance from Table top to Bore top) recorded 400, 407, 445, 495, 405, 405, 405, 403, and 412 mm. Through this study, it was confirmed that there is a difference between the bore size according to each MRI system and the actual cross-sectional area during MRI scanning. Accordingly, if we consider the internal actual area just not bore size at the clinical site, useful diagnostic images can be obtained in the end with better convenience.

Currently the forest area is 6,370,000 hectare (ha) which occupies 63.7% in Korea. The forest has good functions such as production of forest products, conservation of national land, prevention of disasters, etc. However constructing houses near the forest area make bad situation like illegal waste incineration by resident. So research subject is forest fire caused by waste incineration place including facility. And this study was conducted about statistical analysis and research analysis of the 100 waste incineration places including facilities at the country town. Statistical analysis shows that March is 27% which percentage is the highest number of forest fire in 10 years' average. The number of forest fire caused by waste incineration is 45 which is the third highest number in the fire statistic. The distance between waste incineration place including facility and forest area is 30m, 40m and 50m. That 40m (36%) is the most common distance from forest area. The types of waste incineration are ground (62%), the temporary facility made with oil drum can (35%) and other made with steel sheet, concrete, etc. The result of this study is that government and local government must conduct the improvement measure to reduce illegal incineration such as waste pickup area made with rain and wind proof type installed near residence, expenses for waste treatment, enlightenment and training, etc. Also considering their age and income are needed for realistic improvement.

We performed reconnaissance survey on Dashinchilen Nb-Ta REE area and Sant Cu area which are located in southeastern part of Khangai rare metals mineralized belt. In Dashinchilen area, Nb and Ta have been found in pegmatitic granite that is largely distributed in the survey area and muscovite in pegmatite which is an intrusion in paleozoic sedimentary rocks which are mostly composed of sandstone. While grades of Nb and Ta are not high, an outcrop that has high Th and U contents (542 ppm of Th and 56.9 ppm of U) has been found. Average and maximum REE contents in the survey area is three times and seven times, respectively, larger than average REE contents in the crust of the Earth. In Sant area, copper oxides such as malachite has been found in quartzite in paleozoic sedimentary rocks. A sedimentary rock formation that has high grade of Mn (12.4-34.6 %) has been found in the survey area. This sedimentary rock formation is the same formation with that of Ugii Nuur Fe-Mn mineralization which is located about 200 km northwest of the survey area. Average and maximum REE contents in the survey area is two and half times and seven times, respectively, larger than average REE contents in the crust of the Earth. According to the factor analysis for the data of the geochemical analysis, Nb and Ta in Dashinchilen area are highly correlated with muscovite and Cu in Sant area is highly correlated with Mo, Sn, and Bi. Furthermore, the factor analysis results show that Fe in Sant area was deposited with rare earth elements.

Fish community structure between eelgrass beds and an adjacent unvegetated area was investigated. Fishes were collected monthly from two eelgrass beds (Gamak and Yeoja Bays) and one adjacent unvegetated area in the southern sea of Korea between February 2006 and February 2007. The number of species for the Gamak and Yeoja Bays were 33, 28, respectively, while 28 species were identified from the unvegetated area. Leiognathus nuchalis was dominant in both Gamak and Yeoja Bays, while Engraulis japonicus was dominant in the unvegetated area. Cluster analysis conducted on total number of individuals for each species produced 3 groups; group A (appeared only in winter regardless of eelgrass), group B (appeared in eelgrass beds during all seasons except winter) and group C (appeared in the unvegetated area during all seasons except winter). The most important differentiating species between eelgrass beds and the unvegetated area were Lateolabrax japonicus, L. nuchalis, Takifugu niphobles and Pholis nebulosa. Based on the results of this study we can assume that eelgrass beds function as a nursery ground for young fishes from spring to fall, but not in winter.
