A syntaxonomical study about the vegetation of ruined salt field in Chonnam province was carried out and its soil properties were also determined. This study was accomplished by the methods of Mueller-Dombois and Ellenberg. This study was designed to clarify the syntaxonomical and synecological characteristics of the vegetation of ruined salt field in Chonnam province. The annual herbaceous halophyte communities of ruined salt field in Chonnam province were consisted of 5 communities: Salicornia herbacea community, Sueada japonica community, Sueada maritima community, Atriplex gmelini community, Spergularia marina community. And the perennial herbaceous halophyte communities of ruined salt field in Chonnam province were consisted of 3 communities: Aster tripolium community, Carex scabrifolia community, Phragmites communis community. The subsidiary knowledges of this study will make it possible to accumulate information on the distribution pattern of coastal salt marsh vegetation, and also will provide practical information for conservation of coastal ecosystems.

Salt tolerances of Chinese cabbage and cabbage were observed by means of the sand culture and field experiment. The point of 50% yield reduction of Chinese Cabbage was 1% of salt concentration in sand culture. The Na absorption in the salty upland conditions was increased but the absorption of Ca, Mg were interrupted as the salt concentration was raised and there were no differences in the absorption of N and P. The Si absorption was increased at low salty conditions, but the salt concentration was raised, the absorption was interrupted drastically. The cabbage was more stronger salt tolerance than Chinese cabbage, and it was possible to prevent the salt damage significantly by planting on sloping beds instead of planting on the double-row beds in field condition.

To evaluate the effects of pulsed electric field (PEF) application on scalder and chiller water on Campylobacter contamination, four different treatments under three different water conditions including hard scalder water ($55^{\circ}C$), soft scalder water ($45^{\circ}C$) and chiller water, were applied as follows: i) a control treatment with no salt and no electric treatment, ii) a PEF only treatment, iii) a PEF treatment with 0.5% salt water, and iv) a PEF treatment with 1% salt water treatment. The use of PEF in hard scalding water showed an effect of reducing Campylobacter when compared to the control during the 200 s timeframe. With the addition of salt, the intervention caused at least 5.81 log CFU/ml reduction of Campylobacter counts after 200 s of PEF exposure. Similar effects were observed under soft scalding conditions. Campylobacter reductions were evident under chilling conditions with up to 2.00 log for PEF only, 5.77 log for PEF+0.5% salt and 2.69 log for PEF+1% salt treatment in water. Therefore, the current PEF setting for the scalder and chiller water can be successfully used to reduce pathogenic loads of Campylobacter on broiler chicken carcasses, and further research may be necessary to apply it in the poultry processing industry.

As the modern society develops into the digital information age, the application field is gradually expanded and used as an important field. The image data is deteriorated due to various causes in the process of transmitting the image, and typically there is salt & pepper noise. Conventional methods for removing salt & pepper noise are somewhat lacking in noise canceling characteristics. In this paper, we propose a weighted filter using the histogram of the image damaged by salt & pepper noise and a spline interpolation method according to the direction of the local mask.

This study was performed to know the properties and estimation of field application of concrete(Bluecon) using fluosilicate salt based admixture made from by-product during phosphoric acid manufacturing process. Mix proportions for experiment were modulated at 0.45 of water-binder ratio and $0.5-2.0\%$ of adding ratio of fluosilicate salt based inorganic compound. Evaluation for Field application of concrete was carried out batch plant test at remicon factory and building construction. According to results. it was found that slump of concrete(Bluecon) using fluosilicate salt based admixture is higher about 10 to 20 mm than plain concrete, and air content is similar to each other. And the water permeability and crack of bluecon is lower than that of plain concrete.

The effects of Korean solar salt on an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colon cancer C57BL/6 mouse model were studied. Korean solar salt samples (SS-S, solar salt from S salt field; SS-Yb, solar salt from Yb salt field), nine-time-baked bamboo salt (BS-9x, made from SS-Yb), purified salt (PS), and SS-G (solar salt from $Gu\acute{e}rande$, France) were orally administered at a concentration of 1% during AOM/DSS colon cancer induction, and compared for their protective effects during colon carcinogenesis in C57BL/6 mice. SS-S and SS-Yb suppressed colon length shortening and tumor counts in mouse colons. Histological evaluation by hematoxylin and eosin staining also revealed suppression of tumorigenesis by SS-S. Conversely, PS and SS-G did not show a similar suppressive efficacy as Korean solar salt. SS-S and SS-Yb promoted colon mRNA expression of an apoptosis-related factor and cell-cycle-related gene and suppressed pro-inflammatory factor. SS-Yb baked into BS-9x further promoted these anti-carcinogenic efficacies. Taken together, the results indicate that Korean solar salt, especially SS-S and SS-Yb, exhibited anti-cancer activity by modulating apoptosis- and inflammation-related gene expression during colon carcinogenesis in mice, and bamboo salt baked from SS-Yb showed enhanced anti-cancer functionality.

The effects of salt are studied on control of weeds and growth of Korean turfgrass(Zoysia japon-ica Steud.). And the mobility of salt were determined in a lawn field. At post-emergence stage, the growth of the 13 weeds such as Trifolium repens, Erigeron canadensis, Artemisia prieceps, Equi-setum arvense, etc were controlled by treatment of salt and salt water, Pea-annua and Equisetum arvense were tolerant to salt compared with the other 11 weeds. At pre-emergence stage, the salt controlled the germination of the weeds in soil. 300~500 kg /10a salt and 20~30 % salt waterwere enough for the control of weeds, However, salt water injuried the lawngrass except the dormancy stage. The mobility of salt in soil was increased by rainfall. After 160mm of rainfall, the salinity in the soil treated with salt 500kg /l0a was below 0.3 ms/cm in surface soil and about 0.1 ms /cm in soil 30 cm depth. Key words: Soil environmental survey, Korean turfgrass, Salt, Salt water.

As the society increasingly embraces the high - tech digital information age, the field of image processing becomes progressively more branched out and becoming an imperative field. However, image data is deteriorated due to various causes during transmission and salt and pepper noise is typical. Typical methods for removing salt and pepper noise include CWMF, SWMF, and A-TMF. However, existing methods are somewhat insufficient in their ability to remove noise in salt and pepper noise environments. Therefore, in this paper, after it is determined whether noise removal is needed, the following measures were taken. If the center pixel was non-noise, the original pixel was preserved, If it was noise, we proposed a two - dimensional spline interpolation method and a median filter depending on the noise density of the local mask. For the purpose of objective judgment, we compared the results with that of existing methods and used PSNR (peak signal to noise ratio) as a judgment criterion.

This study presents investigation on the technical characteristics and field cases of the salt cavern storage method for large-scale hydrogen storage. The salt cavern storage method enables effective hydrogen storage compared to other methods due to the low porosity and permeability of the rock salt that constitutes the cavern, which is not likely to leak and requires a small amount of cushion gas for operation. In addition, there is no chemical reaction between rock salt and hydrogen, and multiple injection/withdrawl cycles can be performed making it effective for peak shaving and short-term storage. The salt cavern is formed in three stages: leaching, debrining, and filling, and leakage tests are conducted to ensure stable operation. Field applications are currently performing to meet industrial demand in the surrounding area of four sites in the UK and Texas, USA, and salt cavern operation is being prepared for energy storage in European countries such as Germany and France. The investigated results in this study can be utilized as a basic guideline for the design of future hydrogen storage projects.
