ABSTRACT : This study aims to investigate the harmfulness of printing with phthalates and formaldehyde components of pristine preparations, which are commonly regulated by the international harmful substances regulation. The materials used in the experiment were 10 kinds of Prastisol. In order to understand what kind of changes in the prastisol of 10 experimental specimens were caused by thermal reaction, the fabric was printed and heat was applied. The phytogenic plasticizer was able to reduce phthalates of plastisol, and the effect of bio substitution of formaldehyde was determined. In other words, it was concluded that Prastisol, which is a vegetable based plasticizer, can function competitively in terms of functionality, environmentally friendly, and restricted substances of international harmful substances and global sports apparel brands

ABSTRACT : Recently, renewable energy is emerging as a substitute for conventional fossil fuels. In particular, wind power generation is expected to account for 34% of the world's energy production in 2050, despite problems such as noise and irregular production. Therefore, although the technology development is carried out in various countries around the world, the level is poor at present. In general, most of the country is affected by small wind speed of 0 ~ 4m / s. Most of the cities in Korea are installed on roof roofs or between buildings to convert them into electrical energy. Therefore, considering this point, both low noise and aesthetic aspects should be considered at the same time. This study investigates a hybrid windmill that combines a small drag type (elliptical type) windmill in its interior to compensate for the disadvantages of a gyro mill (lift type) windmill for use in urban areas

ABSTRACT : Research was conducted during dry season and wet season to find out the composition of organics, nutrients matter, and suspended solids from the specimen collected from the Nam-Dae River. The parameter was set from Sung-San intersection to Gong-Hang Bridge. Specimen was collected along the parameter in each 2km section. Based on the research, comparing the specimen collected from the beginning of the parameter and the end of the parameter, it shows the specimen collected at the end contain twice of the organics, 3.5 times of the nutrients, and 2.5 times of the suspended solids. Also comparing the specimen collected during the dry season and the wet season, it shows the specimen collected during the wet season contains 1.5 times of BOD, twice of COD, 1.2 times of T-N/T-P, and 2.4 times of SS.

Cesium is considered as the most abundant and hazardous radio toxic pollutant in liquid radioactive waste. The 235uranium operated reactors produce a high yield of 135Cs and 137Cs fission products which are highly radiotoxic and having long half-lives (135Cs : 2x106 yrs: l37Cs : 30.17yrs) The aim of the present investigation is to utilize the activated sericite in the attenuation of radio toxic cesium from aqueous solutions,

In this study, a novel La-bentonite powder (Al-Bnt) and alginate immobilized La-Bentonite beads (La-Bnt-AB) were synthesized and applied for the treatment of aqueous phosphate. The phosphate removal behaviour of adsorbents were evaluated by batch experiments as a function of various parameters such as pH, initial concentration, contact time, adsorbent dose. The adsorption isotherm studies by Langmuir monolayer model showed maximum phosphate uptake capacity of 13 and 44 mgP/g for La-Bnt and La-Bnt-AB respectively. The kinetic studies confirms that the adsorption of phosphate by La-Bnt-AB follows a pseudo-second-order model. The applicability of the synthesized adsorbents was found promising adsorbents in the remediation of phosphate contaminated water.

This paper discarded aqueous solution by utilizing the agricultural waste and of genus Methylene blue a dye, friendly to the environment intended to be removed. For this purpose Methylene blue Density of concentration Ph, experiments relating to the amount of the counter and the procedure, searched for the optimum condition required for removing dye Methylene blue (MB). In MB 20mg/L, pH8, Corncob dose 1Og data, to the high removal rate of a stalk of Indian com, to remove (MB)that optimum conditions.The stem of the com can be easily found in the vicinity of the surroundings, and can be used as a good adsorbent because it is excellent in attracting force and low in cost,

ABSTRACT : Over the last few decades, the occurrence of micropollutants in the aquatic environment has become a worldwide issue of increasing environmental concern. Micro pollutants are the variety of different substances which have adverse environmental effects. these emerging polltants are found in very low concentrations, by the micro or nanogram/L in aqueous systems. Adherence to substance : Diclofenac is a nonsteroidal anti-inflammatory drug. This medicine is use for reducing pain and inflammation in the body. It is one of the most frequently detected pharmaceuticals in the aquatic environment. Because of its low biodegradability and its limited sorption properties onto activated sludge, diclofenac is considered to be one of the most relevant compounds in terms of ecotoxicity and persistence in the environment. The present investigation aims to exploit the hectorite clay as to obtain the novel hybrid materials using the CTAB as organic modifier to form CTAB modified organo-hectorite clay. The modified materials possess hydrophobic core, perhaps, provide an efficient partitioning of organic contaminants diclophenac removal from aqueous solutions even at low level concentration. In addition, the study could contribute to the pharmaceutical industry by eliminating waste water drainage away an diclofenac.
