Recently, Free Trade Area generally moves toward a complex and total zone carrying out the logistics and production function simultaneously. Nevertheless, Free Trade Area of Gwangyang Bay Area performs a traditional logistics function only without a introduction of production function. Therefore, the purpose of this research is to suggest alternatives for strengthening the function of Free Trade Area of Gwangynag port. The main findings of this research is summarized as followings. First, a complex and total Free Trade Area through enhancing a production function is to be established. Second, for an efficient management & operation of Free Trade Area, a cooperative system establishment between Free Trade Areas and a single operation system is necessary.

Rehmannia glutinosa is a perennial herb belonging to family Scrophulariaceae. This study was conducted to evaluate the appropriateness cultivation of R. glutinosa in Southern Gangwon Province. The seed rhizomes of R. glutinosa 'Jihwang 1' were planted in the early May and harvested in the early November. Agronomic characteristics and catalpol content was evaluated in comparison with Eumseong area. As a results, aerial parts of Pyeongchang area in leaf length and leaf width were better than other cultivation area but the leaf number per plant was statistically the same. And underground parts of Eumseong area in rhizome yield and number of rhizome were better than other cultivation area. Conversely, rhizome diameter of Pyeongchang and Jeongseon area were thicker than rhizome diameter of Eumseong area. The fresh rhizome yield of Eumseong, Jeongseon and Pyeongchang area were 1,848, 1,571, and 1485 kg/10a, respectively, higher than the domestic average production of 805 kg/10a. And, catalpol content of Pyeongchang, Jeongseon and Eumseong area were 1.93, 1.62 and 1.99%, respectively. Taken together, R. glutinosa cultivation in the region of southern Gangwon province is considered to be possible, but further evaluation of the economic aspect is needed.

To understand the effects of ocean-dumping of organic wastes on bacteria, bacterial abundance and production, and hydrolytic activities of aminopeptidase (AMPase) and ${\beta}$-glucosidase (${\beta}$-GLCase) were measured 5 times in the euphotic zone of the dumping and non-dumping areas of the East Sea from April 1996 to September 1997. Comparing the depth-integrated values of phytoplankton biomass and bacterial parameters over the euphotic zone of dumping area with those of non-dumping area, we found that activities of ${\beta}$-GLCase in the oceanic dumping area were always higher than those in the oceanic non-dumping area. Also, thymidine-based bacterial production always correlated significantly with leucine-based bacterial production in dumping area (balanced growth), but not in non-dumping area (unbalanced growth). These results seem to be bacterial responses to continuous dumping of organic matter into the dumping area. Further, a relationship between bacterial abundance and production was significant in dumping area, but insignificant in non-dumping area, indicating that control mechanisms of bacterial abundance were different in two areas. Relationships between other bacterial parameters varied with areas and seasons, suggesting that bacteria might be regulated by different factors in spring and summer. Further studies are required to test whether these seasonal variabilities of regulating factor are associated with changes in temperature, temperature-related phenomena, or characteristics of wastes.

In regards to museum planning of Korea, it is mainly depending on overseas cases and relevant domestic books without systematic guideline on the space programme in a museum. Therefore, it is urgently required to establish systematic index as it is incapable of proposing detailed analysis and index in accordance with each element. As various problems occurred due to above reason, total floor area of museum was divided by the area of exhibition section, storage section, research section, and public & other area and its ratio was calculated for statistics targeting 614 museums built after 1990's when many public museums were built with the settlement of local self-governing system and the type of museums was diversified. It was again classified into 4 elements of period, region, scale, and type and then the influence of each element on each section of museum was understood through integrated analysis. First, looking into the space programme in regards to total floor area, the floor area ratio of exhibition section, storage section, and research section decreased and the floor area ratio of public & other area increased with the increase in total floor area. It was because not only rest area but also a space to enjoy various cultures, gaining new experience, and accumulate knowledge is located in public & other area. Second, it was revealed that the ratio of exhibition section and storage section has been decreasing since 1990's and ratio of research section and public & other area has been increasing as they can play various roles such as the education and convenience to satisfy cultural desires of visitor in accordance with current trend. Third, it was proved that floor area ratio of exhibition section is lower than storage section in museums located in highly urbanized region. In addition to this, it was revealed that the floor area ratio of research section is in proportion to the population density. As a result of study, significant relation was displayed in scale, era, and region among 4 elements thus it could be utilized as reference for the space programme of domestic museum planning in the future.

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.

This study aims to investigate characteristics of water quality factors by using survey results of national marine environmental monitoring system from 2004 to 2010 at coastal area of the East Sea of Korea. In this study, we chose statistical methods to analyze the correlation among water quality parameters and principal component analysis for characteristics of each water environment. In addition to this, we evaluated each water's pollution level based on eutrophication standard of OECD, Eutrophication Index(EI), and Organic Pollution Index(OPI). Major factors were chlorophyll a and salt according to the analysis at coastal area of the East Sea. The sea was divided into the south and the central part by Jukbyeon. Also, Jukbyeon in the central part of the East Sea and Gampo in the southern sea coastal waters have been classified separately. The nutritional status of coastal area of East Sea presented Mesotrophic to Oligotrophic level and EI showed less than 1. OPI in all of the coastal area at the East Sea represented that the water quality condition was favorable.

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.

Percentage of aerenchyma area has been closely linked with amounts of methane emitted by rice. A diversity panel of 39 global rice varieties were examined to determine genetic variation for root transverse section (RTS), aerenchyma area, and % aerenchyma. RTS and aerenchyma area showed a strong positive correlation while there existed no significant correlation between RTS area and % aerenchyma. Five varieties previously shown to differ in methane emissions under field conditions were found to encompass the variation found in the diversity panel for RTS and aerenchyma area. These five varieties were evaluated in a greenhouse study to determine the relationship of RTS, aerenchyma area, and % aerenchyma with methane emissions. Methane emissions at physiological maturity were the highest for 'Rondo', followed by 'Jupiter', while 'Sabine', 'Francis' and 'CLXL745' emitted the least. The same varietal rank, 'Rondo' being the largest and 'CLXL745' the smallest, was observed with RTS and aerenchyma areas. RTS and aerenchyma area were significantly correlated with methane emissions, r = 0.61 and r = 0.57, respectively (P < 0.001); however, there was no relationship with % aerenchyma. Our results demonstrated that varieties with a larger root area also developed a larger aerenchyma area, which serves as a gas conduit, and as a result, methane emissions were increased. This study suggests that root transverse section area could be used as a means of selecting germplasm with reduced $CH_4$ emissions.
