Growth experiments was performed with S. platensis under various culture medium conditions (deep sea water + low cost medium). Growth tests for culture medium demonstrated that the deep sea water to low cost medium ratio of 25:75(W/W) was effective in S. platensis with the maximum biomass of 0.88 g/L and minimum medium making cost per production mass of 8.17 KRW/g. The parameter estimation of bio-kinetics (maximum growth rate and yield) for low cost medium results showed that the maximum growth rate, doubling time and yield of N, P, K was obtained under deep sea water to low cost medium ratio of 25:75(W/W) of 0.099 1/day, 3.007 day and 0.170, 0.029, 0.033, respectively. 2016-12-31T15:00:00Z https://oak.chosun.ac.kr/handle/2020.oak/19250 Title: 해조 다당류 소재를 활용한 서방형 방출 수용성 이온 복합체 약물의 기능성 효과 연구 Author(s): 김현경 Abstract: This study investigates the functional effect of induced sustained release of a water-soluble drug without deterioration of drug efficacy and the use of specific carrier materials. A simplex-ion complex formation of the drug is produced based on the seaweed polysaccharide that carry physiological effects such as anti-inflammatory, anti-tumor, anti-viral, anti-mutagenic and immunity enhancement. The specific marine resources used in the experiment were Fucoidan extract and Glycosaminoglycan (GAGs), which is excellent in skin soothing effect and moisturising effect, respectively. Based on the use of such materials, this study has confirmed the formal structure of water-soluble ion complex drug that can be delivered in sustained release to the subject. Furthermore, this study investigates the releasing effect of ion complex of Fuocidan, GAGs and Ca2+, Ba2+ and carries comparative analysis of the newly formed drug to Predniolone drug, which is widely used for dermatitis. 2016-12-31T15:00:00Z https://oak.chosun.ac.kr/handle/2020.oak/19252 Title: 배면 3D 패턴 구현을 위한 고광택 표면 사출 금형 시스템 개발 Author(s): 강형선; 노찬승; 백종진; 오형종 Abstract: The injection Mould products of the vehicle interior decoration and interior are applied to many post-processing techniques such as fusing, painting, plating, etc. in order to achieve various effects. As a result, this increases the price of the product, but it is having difficulty in securing the necessary quality for mass production. Therefore, this study is to test the results of applying a high-gloss 3D pattern to the back of the product by . a green mold system, which is a technology to control the temperature of the mold in a short time, is used to realize a high-gloss surface of the product. Through the research, it is possible to remove the defects on the surface of the product produced by the injection molding, by rapidly heating to a high temperature and precisely controlling the cooling rate to make the resin density of the injection product uniform. 2016-12-31T15:00:00Z https://oak.chosun.ac.kr/handle/2020.oak/19249 Title: 전처리 및 정전선별에 의한 폐자동차 파쇄 잔재물의 분리효율 향상 Author(s): 임시온; 김민규; 한오형; 박철현 Abstract: In electrostatic separation process for recycling of Automobile Shredder Residue (ASR), its separation efficiency is decreased by the influence of conductive matters attached onto the fine glass particles. Hence induction electrostatic separation testwork has been carried out using non-magnetic products obtained through pre-treatment (such as sieving, washing, pyrolysis and oxidation) to remove impurities. From test result, the sieving and water washing are superior to pyrolysis and oxidation for removing the conductive matters. In the electrostatic separation for recovering non-ferrous, a grade of 78 % and recovery of 82 % could be successfully achieved under conditions of 30 kV electrode potential, 45 % relative humidity and 8 cm splitter position. 2016-12-31T15:00:00Z
