This is made of domestic and foreign coal activated carbon of five species, physicochemical adsorption efficient about sterilize products and micro harmful substances and is a result of the economic evaluation. The most well-developed micropores bed volume 123,409 of AC-1 activate carbon appeared to be the best next AC-2, AC-3, AC-4, AC-5 followed by activated carbon was investigated. PFOA and PFOS in the BV 96,000 when evaluating foreign types of adsorption activated carbon adsorption capacity was greater when more than PFOA, PFOS showed that the adsorption well. The economic evaluation of activated carbon usage in chloroform (CUR) was most excellent as a AC-1 4.3 g/day, the next AC-2, AC-3, AC-4, AC-5 there are two types of foreign economic order appears to have appeared, but the current domestic market when applying the price AC-1, AC-3, AC-2, AC-4, AC-5 order was investigated.

The objective of this study was to investigate the effects of the feeding Cordyceps militaris extract on the improvement of the free fatty acid, lipid peroxide, creatinine and enzyme (creatine phosphokinase; CPK, lactate dehydrogenase; LDH, alkaline phosphatase; ALP, lecithin cholesterol acyltransferase; LCAT) activities in the sera of dietary hypercholesterolemic rats (SD strain, male) fed the experimental diets for 5 weeks. Concentrations of free fatty acid, lipid peroxide and CPK, LDH, ALP activities in sera were fairly reduced in the Cordyceps militaris extract administration group (CHE) than in the hypercholesterolemic diet group (CHD). However, no significance was found in the effect of an creatinine concentration among the groups. The LCAT activity in serum was increased in the Cordyceps militaris extract administration (CHE) than in the hypercholesterolemic diet group (CHD). From these results, Cordyceps militaris extracts were effective on the improvement of the lipid components and metabolic enzyme activities in sera of dietary hypercholesterolemic rats.

Chapssaltteok is a Korean dessert that consists of glutinous rice cakes filled with sweet bean paste. Emulsifiers and saccharides are used as anti-staling agents in the cakes to increase their shelf life. this is especially necessary for industrialized glutinous rice cakes, such as chapssaltteok. This study was conduvted to evaluate the suppression effects of retrogradation in chapssaltteok under various concentration of saccharides and emulsifiers (SP). Glutinous rice cake was manufactured with a multifunctional extruder, wrapped with polyethylene film, and stored at 4℃ for five days. The texture properties of the samples were assessed using a texture analyzer. The results showed that the addition of 0.5% SP, 15% sucrose, 20% low DE syrup, or 10% maltose effectively for delayed the retrogradation during the storage period.

This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, β-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

The aims of this study were to investigated the occurrence of caffeine and carbamazepine in Nakdong river basin (8 mainstreams and 2 tributaries) and the behavior of caffeine and carbamazepine under drinking water treatment processes (conventional and advanced processes). The examination results showed that caffeine was detected at all sampling sites (5.4 ∼558.5 ng/L), but carbamazepine was detected at five sampling sites (5.1∼79.4 ng/L). The highest concentration level of caffeine and carbamazepine in the mainstream and tributaries in Nakdong river were Goryeong and Jinchun-cheon, respectively. These pharmaceutical products were completely removed when they were subject to conventional plus advanced processes of drinking water treatment processes. Conventional processes of coagulation, sedimentation and sand-filtration were not effective for their removal, while advanced processes of ozonation and biological activated carbon (BAC) filtration were effective. Among these pharmaceuticals, carbamazeoine was more subject to ozonation than caffeine.

This study aims to analyse the landscape ecological characteristics of 39 rural villages in Korea and classify them according to their characteristics. After producing a land-use map of rural villages, this study quantified the landscape ecological characteristics of the subject sites as 18 landscape indexes using Fragstats. By applying the landscape index as a variable, selecting 4 factor through principal component analysis and conducting a cluster analysis, it classified them into 3 groups. Rural villages of Korea have their unique types of land-use due to the influence of physical environment such as geography, climate and ecology as well as the social and cultural influence, and the characteristics of land-use can be analysed and classified using the landscape index, the quantified landscape ecological characteristics.

This study was conducted to examine the influences of chitosan, sericin and collagen extract complexes (1:1:1, w/w/w, CSC-F-005) in blood glucose and lipid concentrations in the sera of streptozotocin (STZ, 55 mg/kg BW, IP injection)-induced diabetic rats (SD strain) fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol, atherosclerotic index, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride (TG) and phospholipid (PL) in serum were effective on the metabolic regulation in diabetic rats. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the extract complexes (CSC-F-005) than in the diabetic rats. The results shown above suggested that CSC-F-005 extract complexes supplementation effectively improvement of blood glucose and lipid components in the serum of STZ-induced diabetic rats.

The objective of this study was to assess improvements caused by chitosan, sericin and collagen peptide extract complexes (1:1:1, w/w/w, CSC-F-005) in lipid concentrations in the sera of dyslipidemic rats (SD strain) fed on experimental diets for 5 weeks. Serum concentrations of total cholesterol, HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol, atherosclerotic index, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride, phospholipid and blood glucose were effective on the metabolic regulation of dyslipidemic rats. The activities of alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase in serum were remarkably lower in the extract complexes (CSC-F-005) than in the dyslipidemic model. From the above results shows that CSC-F-005 extract complexes were effective on the improvement of the lipid metabolism in sera of dyslipidemic rats.

Atlatoxin은 Aspergillus속 곰팡이로부터 생성되며 사람에게 있어서 간독성, 및 간암을 유발하는 잠재력을 가진 대표적 곰팡이 독소이며, 생체에 섭취된 은 여러 가지 대사경로를 거쳐 동물 조직 내에 축적되는 것으로 알려져 있다. 방사선은 수술, 항암약물요법과 더불어 임상 시 중요한 치료방법이나 정상세포에 방사선을 조사하였을 때 반응성이 높은 활성산소와 과산화라디칼()을 생성하여 세포막의 불포화 지방산을 지질 과산화물로 변성시켜 세포 산

최근들어 사장교나 현수교와 같은 케이블 형식의 장대교량이 많이 건설되거나 계획중에 있다. 하지만 도로교 설계기준에 제시된 풍하중 산정시 중요한 요인인 기본풍속 산정함에 있어서 1995년까지 측정된 풍속자료를 근거로 한 일반교량에 적합한 풍속을 명시하고 있어 장대교량에 적합한 풍속에 대한 재검토가 필요한 상황이다. 본 연구에서는 태풍의 빈도가 높고 대부분의 장대교량이 건설되고 있는 서남해안지역으로 구체화하였다. 풍하중기준과 같이 극치I형분포(Gumbel분포)에 의해 일반교량에 적용할 100년, 장대교량에 적용할 200년 재현기대풍속을 적률법과 최소자승법의 두 가지 방법으로 추정하고, 극한 상황인 해상에서 불어오는 풍속으로 보정하여 지상풍속보다 약 17%정도 큰 값을 추정하였다. RMS error 방법에 의해 재현기대풍속의 적합성을 평가한 결과 최소자승법이 서남해안지역의 경우 적합성이 우수하였다.
