The extracts drawn out from Artemisia princeps by water was concentrated. Using this concentrate the silk and the cotton fabrics were dyed, and they were measured with the K/S value, surface color and mordant quantity in order to evaluate the dyeability and the antimicrobial activity. The results are as follows; 1. The K/S value of the silk fabric was much higher than that of the cotton fabric. And the color yield of the dyed silk fabric was most efficient for the premordanting method. 2. The surface colors on the dyed fabric depended heavily upon mordants used or mordanting methods. For all cases, the value of the dyed fabric was generally dark. For the Cr-mordant among various mordants, the chroma produced clear and the color difference was distinct when using the Fe-mordant. 3. On the other hand the amount of absorbed mordant in the silk fabric was larger than that of the cotton fabric. And the Cu-mordant was most efficient. 4. The color fastness was significantly improved when mordants were added. Cr-mordant improved best in all of the dry cleaning, wet cleaning and perspiration fastness. Iron and abrasion fastness showed over 4-5 grade regardless of any mordant. And light fastness was best in Cu-mordant. 5. The Cu-mordant showed the greatest antimicrobial activity in both of mordant treat silk and cotton fabrics.

To find characteristics and areas of greater risk of oil spill at the coastal waters in Korea, some of risk factors were analyzed with historical data of oil spill and marine traffic. As a result, it is characterized that frequency of oil spill is increasing year by year and greatest percentage of spill source is fishing boat. It is proposed that the ports of Ulsan, Yeosu, Incheon and Pusan will be designated as primary area of risk as they have a higher risk of oil spills and its response authority is required to maintain appropriate regional response capability for prompt and effective response to a future spill incident. In addition, the regional response equipments at Ulsan are examined under a assumption of a medium size spill and it is found that the use of chemical dispersant can be an alternative when mechanical containment and recovery is not feasible in this area, and the existing response equipments may be appropriate to address that size of spill. However, the response authority is required to maintain more numbers of stronger boom for unsheltered waters and more quantity of concentrate dispersant to disperse all spilled oils on the water, furthermore the response authority should be prepared for a possible future catastrophic spill with sufficient equipments.

A conventional electrolyzing cell has been made by an ion exchange membrane inbetween parallel plate electrodes. A low dc voltage is applied to the electrodes for electrolyzing and the efficiency is remained in low. in this study, a novel electrolyzing cell with a pair of slit-type third electrodes installed inbetween parallel plate electrodes has been proposed and investigated experimentally. And pulse power wa supplied to between each electrodes. This slit type of third electrodes can concentrate the strong electric fields at the every its edges to accelerate the electrolyzing powers, and to generate oxygen bubble discharges for generating oxidants. And moreover the slits eliminate the space charge limiting action and the temperature of the water by leaking out through the slits from electrolyzing region to outside of the main electrode region. As a result, it was found that a strong electorzed water of pH 2.8 and pH 10.5 and oxidants dissolved water of 1 [ppm] in acidic water were obtained with a tap water fed at the electric current of 2 [A], which however were several times higher oxidant and ion concentration quantity compared with the conventional cell.

Analysis of hydrological safety as well as the determination of many substance concentrations are necessary when bioreactor systems are introduced to landfill operations. Therefore, hydrological and substance balance model was developed since it can be applied to various bioreactor landfill operation systems. For the final evaluation of the model's effectiveness, four different methods of injections (leachate alone, leachate and organic waste water, leachate and reverse osmosis concentrate, and all the above three combination) was applied to 1st landfill site of Sudokwon landfill. As a result, the water content of the hypothetical cases for four different systematic bioreactors is projected to be increased up to 35.5% in next 10 years, and this indicated that there will be no problems in meeting the hydrological safety. Also, the final $Cl^-$ concentration after 10-yr time period was projected to be between from minimum 126 to maximum 3,238 mg/L, which could be still a decrease from the original value of 3,278 mg/L. According to the proposed model, whether the substance concentration becomes increased or decreased largely depends on the ratio of initial quantity of inner landfill leachate and the rate of injection.

To develop a diet for Hanwoo steers during the late fattening phase, three different feeding treatments were investigated: a group fed concentrate and rice straw separately (Formula feed), a group fed TMR during the whole late fattening period (TMR), and a group fed TMR plus concentrate (Formula-TMR). Thirty Hanwoo steers 20 months of age (average body weight = 445 kg) were allotted by a completely randomized design into three treatment groups (ten steers in each group). The impact of these treatments on the performance, carcass traits, and blood composition related to body fat synthesis was assessed. The average dry matter and TDN intake were greater in Formula-TMR compared to other treatments (p<0.05); however, body gain, carcass weight, meat production index, and fat color were not affected by dietary type. Blood characteristics, such as concentrations of retinol, insulin, and leptin were not affected by any of the treatments; however the marbling score of the longisimus muscle was significantly higher in Formula-TMR (p<0.05), which was relatively high in blood leptin concentration. The muscle texture, meat quantity index, and meat quality index were highest in the Formula feed, TMR, and Formula-TMR, respectively (p<0.05).

The total phenolics, total flavonoids, and antioxidant capacities of ten commercial products of Japanese apricot (maesil) were evaluated, including four kinds of alcoholic drinks, two kinds of soft drinks, and four kinds of concentrate found in the Korean market. The daily per capita consumption (g/capita/day) of each product was calculated from in the existing dataset of the Korea National Health and Nutrition Examination Survey in 2010. Using the combined datasets indicated above, the daily per capita intake of total phenolics from maesil product consumption was found to be 1.05 mg gallic acid equivalents. The daily per capita intake of total flavonoids was determined to be 0.13 mg catechin equivalents, and the daily per capita intake of antioxidant capacities were measured at 0.70 mg vitamin C equivalents (1,1-diphenyl-2-picrylhydrazyl assay), and at 1.04 mg vitamin C equivalents (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) assay). The daily per capita intakes of total phenolics, total flavonoids, and antioxidant capacities were influenced by the daily quantity of consumption of maesil products, as well as their compositional contents.

This study was carried out investigate the effects of dietary supplementation of agricultural by-product feed(persimmon-pell+barley bran+fermented rice bran+activated carbon) on calves disease, growth and carcass characteristics of Korean native steer. A total of twenty Korean native steer were allocated into four feeding group and assigned to four dietary treatments: Control(normal concentrate as a basal diet), T1(1% addition of by-product feeds), T2(3% addition of by-product feeds) and T3(5% addition of by-product feeds). The calf diarrhea was the highest at Control, while T3 was the lowest. The breath disease was the lowest at T2, occurrence with diarrhea and breath disease was the highest at Control. The daily gain was orderly ranked as T2(0.76kg)>T1(0.7kg), T3(0.70kg)>Control(0.67kg). The back fat thickness was orderly ranked as T2>T3>Control>T1, eye muscle area was orderly ranked as T3>T1>Control>T2. Grade of meat quantity was the highest at T1(2.3), but fat color, firmness and maturity tends to have a similar result. The marbling score and quality grade of T2 were the highest at 5.0 and 3.5, respectively. Based on the study, agricultural by-product feeds are able to many used for various purposes at disease reduce, increment of meat quantity and improvement of quality grade.

A feeding trial was conducted to examine the effect of high-temperature-micro-time (HTMT) processing of diets containing extruded soybean (ESB) in high quantity on milk fat production, metabolic responses, and the formation of conjugated linoleic acid (CLA) and trans-vaccenic acid (TVA). Twenty-one multiparous Holstein cows in mid-lactation were blocked according to milk yield in the previous lactation. Cows within each block were randomly assigned to either normal concentrate or HTMT treated diets containing ESB (7.5% HTMT-ESB and 15% HTMT-ESB). It was hypothesized that the HTMT-ESB would affect the undegradable fatty acids in the rumen and, thus, would modify the fatty acid profile of milk fat. Both 7.5% and 15% HTMT-ESB did not affect milk yield, fat, protein, lactose and solid-not-fat (SNF), but the proportion of cis-9, trans-11 CLA in milk fat was significantly increased by these treatments. Content of TVA in milk fat was not affected by HTMT-ESB. The HTMT-ESB influenced the fatty acid profile in milk fat, but there was little difference between 7.5% and 15% of supplementation. HTMT-ESB feeding significantly decreased the concentration of plasma insulin and glucose, while plasma growth hormone (GH), triglyceride (TG), non-esterified fatty acid (NEFA) and HDLcholesterol were increased by 7.5% and 15% ESB-HTMT supplementation in comparison to the control group (p<0.05). However, no significant difference was observed in plasma LDL-cholesterol, insulin like growth factor (IGF)-1, T3, T4, and leptin concentrations among treatments (p>0.05). The present results showed that cis-9, trans-11 CLA production was increased by HTMT treatment of dietary ESB without reduction of milk fat, and the unchanged milk fat and yield was assumed to be associated with the constant level of thyroid hormones, leptin, and IGF-1.

본 연구에서는 한국어의 사·피동문을 실어증 환자가 처리하는 양상에 대하여 살펴보았다. 한국어의 사·피동문은 용언에 파생접사가 붙어 이루어지는 경우와 '-게 하다'나 '-어 지다'와 같이 구문 변형으로 하여, 실어증 환자에게 실험을 하였다. 실험에 참여한 환자는 명칭성 실어증 환자, 이해성 실어증 환자, 표현성 실어증 환자, 전반성 실어증 환자로 구성되어 있다. 본 실험에서는 단어 채워 넣기 과제(word completion task)를 사용하였다. 명칭성 실어증 환자의 경우 피동에서는 처리 오류를 보이는 반면, 사동에는 아무런 문제도 보이지 않았다. 표현성 실어증 환자의 경우, <피동-비변형>에서 오류를 많이 보였다. 이를 통해 한국어의 사·피동은 영어와 달리 통사상의 문제가 아니라는 결론을 내릴 수 있다. 즉 이미 사·피동 접사에 의해 파생된 단어가 어휘부에 저장되어 있고, 각 단어의 논항 정보에 따라 문장이 생성되는 것이다. 표현성 실어증 환자가 피동의 비변형에서 지배적인 오류를 보이는 것은 피동의 비변형이 타동사로서 변형인 피동형에 비해 하나의 논항을 더 취하기 때문이다. 이해성 실어증 환자의 경우 사·피동 생성에 별 어려움을 보이지 않았다. 이는 이해성 실어증 환자가 개별 어휘의 논항 정보에 손실을 적게 입고 있음을 시사하는 결과이다. 본 연구에서는 서로 다른 유형을 보이는 환자들을 대상으로 한국어의 사·피동의 처리양상을 대조한 결과, 첫재 사·피동은 서로 다른 통사, 의미상의 처리 양상을 보이고 있고, 둘째 파생접사가 결합된 형태로 어휘부에 저장되어 있는 개별 사·피동사에 의해 형성되는 것임을 확인하였다.d CO2 quantity causes flame temperature to fall since at high strain retes diluent effect is prevailing and at low strain rates the products inhibits chain branching. It is also found that the contribution of NO production by N2O and NO2 mechanisms are negligible and that thermal mechanism is concentrate on only the reaction zone. As strain rate and CO2 quantity increase, NO production is remarkably augmented.our 10%를 대용한 것이 무첨가한 것보다 많이 단단해졌음을 알 수 있었다. 혼합중의 반죽의 조사형 전자현미경 관찰로 amarans flour로 대체한 gluten이 단단해졌음을 알수 있었다. 유화제 stearly 칼슘, 혹은 hemicellulase를 amarans 10% 대체한 밀가루에 첨가하면 확연히 비용적을 증대시킬 수 있다는 사실을 알 수 있었다. quinoa는 명아주과 Chenopodium에 속하고 페루, 볼리비아 등의 고산지에서 재배 되어지는 것을 시료로 사용하였다. quinoa 분말은 중량의 5-20%을 quinoa를 대체하고 더욱이 분말중량에 대하여 0-200ppm의 lipase를 lipid(밀가루의 2-3배)에 대하여 품질개량제로서 이용했다.
