본 연구는 여러 가지 기능성과 생리활성을 가지고 있는 도 라지를 활용하고자 도라지 분말을 0%, 1%, 3%, 5% 첨가하 여 도라지 쿠키를 제조한 후 그 품질 특성을 측정하였다. 도 라지 분말의 첨가량이 증가할수록 쿠키의 수분 함량과 pH 가 낮아졌다. 쿠키의 색도는 도라지 분말의 첨가량이 많아질 수록 명도(L)는 감소했으며, 적색도(a)와 황색도(b)는 증가하였 다(p<0.001, p<0.01). 쿠키의 퍼짐성 지수는 도라지 분말의 첨 가량이 많아질수록 높아졌으나, 도라지 분말의 첨가량과 쿠 키의 퍼짐성 간에는 통계적으로 유의한 차이를 나타내지 않 았다. 도라지 쿠키의 경도는 첨가량의 증가와 함께 낮아지는 것으로 나타났다. 도라지 쿠키의 관능적 특성은 1% 첨가군이 색과 맛, 조직감, 전체적인 기호도가 가장 높았으며, 풍미는 무첨가군이 가장 높았고, 도라지 분말 첨가량이 증가할수록 낮았다(p<0.001).

본 시험은 육성기 흑염소에 있어서 조사료원이 볏짚 위 주일 때, 농후사료 급여 수준이 발육, 사료이용성 및 경제 성에 미치는 영향을 구명하기 위해 실시하였다. 육성기 암 컷 흑염소 40두를 공시하여 농후사료 급여수준을 체중의 1.5% (T1), 1.8% (T2), 2.1% (T3) 및 자유채식구(T4)로 나누 어 급여 하였고 조사료원은 볏짚을 자유채식 하도록 하였 다. 그 결과, 일당 증체량은 T1 (1.5%), T2 (1.8%), T3 (2.1%) 및 T4(자유채식)구가 각각 50.23, 60.37, 71.46 및 98.90 g으로 농후사료의 급여 수준이 높아질수록 유의하게 높았으며(p<0.05), 조사료인 볏짚의 사료 섭취량은 농후사 료 급여수준이 증가 할수록 유의적으로 감소하는 결과를 보였다(p<0.05). 경제성 분석에 있어서 육성기 흑염소 경영 비는 농후사료를 1.5%, 1.8%, 2.1% 및 자유 채식하였을 때 각각 46,704원, 49,998원, 54,701원 및 74,613원으로 농후사 료의 급여수준이 증가할수록 경영비는 증가하였다. 이는 증체량에 있어서 T4(자유채식)구가 가장 많이 증가하였지 만 T3 (2.1%)구보다 사료비에 있어서 두당 19,912원 더 많 이 들었다. 이상의 시험 결과를 종합하여 고려할 때, 육성 기 흑염소에 있어서 조사료 원이 볏짚 단용일 경우에는 농 후사료를 2.1% 수준으로 급여하는 것이 가장 바람직할 것 으로 사료 된다.

We investigated the quality characteristics of cookies prepared following the addition of various concentrations of used Hongkuk powder (0%, 1%, 3%, 5%, all w/w) as a substitute for flour. In this study, the moisture content of dough decreased and pH increased by adding Hongkuk powder. The L and b value were decreased significantly, but the a value of cookies increased by addition of Hongkuk powder. The spread factor of cookies was slightly decreased by the addition of Hongkuk powder. The hardness of the control group was higher than that of the cookies prepared with different levels of Hongkuk powder. The result of the sensory score showed that cookies added with 1% Hongkuk powder had higher taste, flavor, and overall acceptability scores than other samples. As a result of this study, the quality of cookies with the addition of 1% Hongkuk powder were the most suitable in terms of its taste, flavor, texture, and sensory properties.

To reproduce the brewing process of Hongkuk-ju and to identify the functional properties of it, Hongkuk-ju was brewed using different additions of Hongkuk (100%, 90%, 70%, 50%) and Nuruk (0%, 10%, 30%, 50%). The quality elements, including pH, total acidity, reducing sugar content, alcohol content and pigments (yellow, red, monacolin K and citrinin), were measured. The pH values of Hongkuk-ju showed a slight difference (pH 4.08～4.58) right after the 1st stage mash; further, the pH on all groups (H1, H2, H3 and H4) in the terminal of the 2nd stage mash (9 days in fermentation) were similar, ranging approximately at pH 3.70. The total acidity change did not show a difference directly the 1st stage mash (nearby 0.2 %); however, it began to show a slight difference at the terminal of the 2nd stage mash between the range of 0.69～0.76%. The residual reducing sugar of the content was decreased with the increased Nuruk content. The alcohol concentrations of the treatment brew with Nuruk ranging from 12.3% to 13.7% were higher than Hongkuk on its own. The yellow and red pigment contents of Hongkuk-ju ranged from 7.2～8.8 O.D. units (yellow pigment) and from 4.4～5.1 O.D. units (red pigment). The production of monacolin K and citrinin was the highest (9.48 ㎎/㎏ and 10.14 ㎎/㎏) when the treatment solely brewed Hongkuk. The concentration of Nuruk and the preparation of the seed mash from it were critical factors compared to the treatment of rice in brewing Hongkuk-ju

This study was conducted to determine the effect of dietary whole-crop barley silage on the daily feed intake, daily weight gain, velvet antler yield and economic efficacy in elk during growth. A total of 21 elk (average BW 303 kg, 5 years old) were allotted randomly to three treatments. The three treatments were T1 (hay diet), T2 (whole-crop barley silage), and T3 (50% hay + 50% whole-crop barley silage). The average daily weight gain of T3 was higher than the others throughout the entire experimental period. The average daily feed intake of elk in decreasing order was as follows; T1>T3>T2. The velvet antler yield was higher in T3 group (8,585 g) compared with T1 (8,037 g) and T2 (7,713 g). However, there were no significant differences in the average daily feed intake, average daily weight gain, or velvet antler yield (p>0.05). In economic efficacy, T3 was gained about 29~43% more value than T1 or T2. In conclusion, the mixed feeding of 50% hay and 50% whole-crop barley silage was more effective than feeding hay of barley alone, in terms of average daily weight gain, velvet antler yield, and economic efficacy in elk.

A computational fluid flow analysis of a car has been accomplished to explain the lift characteristics according to the changes of wiper angle and car speed. The present study established the process to get the lift coefficient distribution on the whole range of a wiper operating angle. From the result of the present research, it could be seen that the lift coefficient of a wiper with the lower wiper angle had relatively smaller magnitude. On the other hand, the lift coefficient with the wiper angle near 45° was relatively larger than that with the other wiper angles. The present study also verified the usefulness of the lift coefficient that the lift distributions of various car speeds could be derived from the result of a lift coefficient distribution for only a car speed.

In order to produce Hongkuk-ju, the production and characterization of Hongkuk (Monascus red koji) by Monascus anka KCTC 6121 were investigated. The optimum cultural conditions for the production of enzyme (α-amylase and glucoamylase) and pigment (yellow and red) from this strain on solid culture (steamed rice) were examined. The results showed that the production of α-amylase and glucoamylase reached the highest for 9 days and 8 days, respectively. Since then, the productions decreased slightly. The production of yellow and red pigments reached the highest for 8 days, decreasing slightly soon after. The optimal content of the initial moisture equally presented 30% in the enzyme and pigment production. After that, the enzyme production decreased slowly, whereas pigment production decreased sharply. The optimal temperature of the culture also showed 30℃ in the production of enzyme and pigment. It was found that the initial inoculum size in enzyme and pigment production was 10% and 20%, respectively. Under these optimal conditions, the production of monacolin K and citrinin was 74.35 ㎎/㎏ and 5 ㎎/㎏ for 12 days, respectively.

This research focuses on the role of Giovanni Marinioni during the formation of the modern cartography and cadastre during the 18th century. Initial study began with Giambattista Nolli's Roman map noticing not much information was available to acknowledge his activities during his Milan period before the departure to Rome. It became evident that Marinoni was a key person to understand the complex circumstances in which the professional training and formation of Giambattista Nolli took place as later worked as an anonymous intern during the elaboration of Theresian Cadastre of Milan. The other important figures are Leandro Anguissola and Giovanni Filippini. Anguissola's position and precedent work facilitated Marinoni's multidisciplinary activities that he had performed in Vienna and Milano in the field of making urban maps of those two cities. On the other hand, Filippini not only collaborated with Marinoni but also introduced Nolli in the field of cartography. These activities show transitional and dual aspects that characterized the period in which important irreversible changes that occur during the reign of Habsburg empire and in the rest of the Europe toward the formation of modern society and state. Marinoni's theories and praxis greatly influenced Nolli's later commitment under the Savoia and later on the elaboration of the 'Pianta Grande di Roma' in 1748.

We investigated the quality characteristics of cookies prepared after the addition of various concentration of used guava leaf powder(0%, 1%, 3%, 5%, all w/w) as a substitute for flour. In this study, as guava leaf powder concentration rose, there was a decrease in the water content level. In addition, color, spread factor, hardness and sensory evaluation of the cookies were examined. The results showed that with an increase in guava leaf powder concentration, the L value decreased significantly, while the values for a and b of cookies increased when more guava leaf power was added to cookies. The spread factor of cookies decreased, but the hardness of cookies increased significantly, as guava leaf powder concentration increased. Cookies containing 0% and 3% of guava leaf powder showed a similar sensory evaluation score in terms of color, taste and flavor of the cookies. In the case of texture and overall consumer acceptability, cookies with 3% of guava leaf powder showed the highest score.

1. 계획경제체제에서 농업부문의 비효율성 문제가 심각하게 제기되어왔으며, 시장경제로의 체제전환이 이러한 만성적인 농업부문의 비효율성을 극복해 줄 것으로 기대함. 하지만 농업선진국과 체제전환국간에 농업생산성 격차가 상당히 큰 수준이며, 체제전환국 간에도 농업생산성의 차이가 큰 것으로 나타남. 2. 이러한 체제전환국간 농업부문의 성과 차이는 각 국의 부존자원, 초기조건 그리고 이행과정에서의 시장지향적 정책의강도 등에 영향을 받는 것으로 보고되고 있으나 이에 대한 실증연구는 미미한 편임. 따라서 실증분석을 통해 부존자원과 초기조건 그리고 이행과정에서의 정책이나 소유권의 배분 방식등에 따라 생산성으로 계측된 농업부문의 성과가 어떻게 달라지는지를 이해하는 것은 향후 이들 국가의 농업부문의 생산성 제고를 위한 정책 방향 설정에 매우 중요함. 3. 본 논문의 연구목적은 체제전환 국가들의 시장경제로의 편입 이후 농업 생산성의 변화를 실증적으로 분석하고 이러한 생산성 변화의 결정요인 분석을 통해 체제전환국의 농업정책방향 설정에 시사점을 제공하는데 있음. 4. 본 논문의 시사점으로는 (1) 체제전환 이전의 토지 원소유자에게 토지 반환, (2) 시장경제로의 개혁이 원활하게 이루어지도록 정책적제도적 방안 마련, (3) 체제전환정책을 입안함에 있어 특정 국가가 지닌 초기조건 고려임.
