This study was performed to develop and evaluate the effects of Team-Based Learning(TBL) on cardiac problem in adult nursing. The study measured problem-solving ability, critical thinking disposition, academic achievement and, class satisfaction for learning outcomes of course. Pretest-posttest design with nonequivalent control group was utilized to analyze the effects of TBL. Experimental group and control group each consisting of 52, 54 participants was picked from the junior students. The experimental group was given the TBL for 6 hours and control group was given a lecture and case-based announcement class. In results, significant improvements were found in problem-solving ability(F=5.92, p=.017), and class satisfaction(F=5.80, p=.018). Critical thinking disposition and academic achievement of experimental group were improved than those of control group, but there were not statistically significant difference.

This study was attempted to examine the sensory quality, the degree of gelatinization, color, texture and moisture content of Paeksulgies made with black color rice. The results were as follows: The moisture contents was about 32-36%. L-value on the control group was high, 94.74 and $A_1$, $A_2$, and $C_1$ group were 78.72, 78.58, and 78.43 respectively. As the amount of color rice was increased, L-value on the Paeksulgis was decreased. The gelatinization of Paeksulgis added with color block rice was most increased at C group and D group. In sensory quality. Paeksulgis added with 4-10% block color rice showed the most favorable sensory evaluation.

The rheological properties of dough made with 0% 1 % 2% or 3% Corni fructus flour were investigated Rapid Visco Analyzer (RVA) analysis showed that the initial pasting temperature increased with increasing Corni fructusflour content, while the peak viscosity decreased. The water absorption, stability, development time, elasticity and valorimeter value of the dough, as determined using a farinograph and alveograph, decreased with increasing amounts of Corni fructusflour, while weakness increased. The extensibility, fermented volume and consistency of the dough increased gradually with increasing Corni fructus flour content. These results indicate that the addition of Corni fructus flour affects the rheological properties of bread.

본 시험은 냉동 및 해동 방식에 따른 토종오리 고기의 이화학적 특성을 조사하기 위해 수행하였다. 처리구는 8주령 오리육을 대조구(Control)로 하고 처리구는 냉동방식 2가지(급냉, $-50^{\circ}C$; 완냉, $-20^{\circ}C$)과 해동방식 2가지(완해동, $4^{\circ}C$ 냉장해동; 급해동, $13^{\circ}C$ 유수해동;의 $2{\times}2$ 복합요인으로 하여 총 5처리구, 처리구당 3반복, 반복당 3점(2수/점)으로 나누었다. 공시재료는 각 처리구에서 발생된 8주령 토종오리 수컷을 처리구당 18수씩 선별하여 도압하고 1개월간 저장 후 분석에 이용하였다. 명도는 완냉시키거나 완해동할 때에 대조구와 유의적인 차이가 있었으나(P<0.05), 적색도와 황색도는 처리구간 유의차가 없었다. 가열감량과 보수력은 급냉시키거나 급해동시킬 때 대조구에 비해 유의적으로 높게 나타났으나(P<0.05), 전단력은 대조구에 비해 낮게 나타났다(P<0.05). 가열감량, 전단력, 보수력은 냉동 처리구 사이에서는 유의적인 차이를 보이지 않았으나, 가열감량은 급해동과 완해동 사이에 유의차가 나타났다(P<0.05). 수분, 지방, 단백질, 조회분의 함량은 냉동 처리구와 대조구 사이에서 유의차가 없었으나, 수분함량은 급해동 처리구에서 완해동 처리구에 비해 유의적으로 높게 나타났으며(P<0.05), 단백질 함량은 완해동 처리구에서 대조구에 비해 높게 나타났으나(P<0.05) 해동 처리구간에는 유의적인 차이가 없었다. 지방과 단백질 함량은 해동 처리구 사이에서 유의적인 차이를 보이지 않았다. 결론적으로, 본 시험에서는 냉동과 해동 방식에 따른 오리고기의 특징을 보여주고 있으며, 이런 결과들은 토종오리 산업과 오리육 생산 산업에 큰 도움이 될 것이라 사료된다.

The potential use of Doenjang in place of salted-fish juice as an ingredient in Kimchi fermentation was examined, to improve Kimchi qualities such as flavor and taste. Quality characteristics were monitored during progressive fermentation of Kimchi with Doenjang (KD) at 7 d intervals for 28d at constant temperature $(10^{\circ}C)$. The data showed that the pH of KD was somewhat lower than that of the control as fermentation progressed. The titratable acidity in KD was linearly proportional to the pH change. Both the growth of lactic acid bacilli and total bacteria in Kimchi were inhibited in KD compared to control. In terms of color, the L, a, and b values of KD were all lower than those of control. In sensory evaluation, the taste, flavor, color, and overall acceptability of the new form of Kimchi were increased significantly by addition of 5 % (w/w) Doenjang (p<0.05). All data indicated that the color and taste properties of KD were improved by addition of Doenjang during fermentation.

Transglutaminase (TG) was prepared from Streptomyces mobaraensis to improve texture and self-life of food. In preliminary experiments, texture of the dough was not improved due to the interference in microbial TG reaction by proteases present in the crude enzyme. Among the cation exchange resins tested for the removal of proteases, MonoPlus S 100 was the most efficient. Further purification steps with a quaternary ammonia salt resin and gel permeation chromatography effectively removed proteases from crude enzyme. Molecular weight of purified enzyme was about 38,000 on SDS-polyacrylamide gel electrophoresis. Farinograph data showed the addition of purified enzyme to wheat flour gave higher stability and lower weakness values those that of crude enzyme.

Effects of Monascus koji on color, peroxide value, textural properties, microbial stability, and sensory characteristics of bologna-type sausage during storage at $4^{\circ}C$ for 22 days were studied. Addition of 2% Monascus koji resulted in attractive color and distinctly improved color retention. Lipid oxidation was effectively inhibited by lowering the level of peroxide value. Textural properties and microbial stability of the samples were not affected, whereas color was improved by the addition of Monascus koji. Utilization of Monascus koji in meat product could reduce the use of nitrite and inhibit lipid peroxidation during storage.

Xanthan gum (XG) was investigated for use as a thickening and stabilizing agent in kimchi during fermentation at 10$\^{C}$. The mixing ratios of XG to salted Chinese cabbage were 0.1, 0.3 and 0.5%. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured. pH and reducing sugar content showed abrupt decreases after 5 day lag time until 20 days, while titratable acidity steadily increased during fermentation. The addition with 0.5% XG retarded the change rates of pH and titratable acidity showing the slowest change. Kimchi samples added with 0.1% and 0.3% XG maintained a higher reducing sugar content during the whole fermentation period of 30 days. Microbial loads showed an abrupt increase from 5 to 10 days, and maintained a nearly same load thereafter. Kimchi sample added with 0.3% XG showed better scores in color, aroma and taste.

Pysicochemical and sensory characteristics of cookies with various levels of functional rice flour were investigated in this study. Dough pH of 10% substituted group and Spreadability of 20 and 30% substituted group had significantly higher values than that of control group. Density of Dough had significantly the largest value of 1.27 with 10% substituted sample group. The L value of brightness in control group had significantly the largest value of 69.31. The b value of 20% substituted sample group had significantly the largest value of 35.60. Results of sensory characteristics showed significantly higher savory aroma, savory flavor, hardness and brownness with 10% substituted sample group. Acceptance test of cookies with 20% substituted sample group showed higher overall acceptability than those of others. Quality caracteristics of 10 to 30% subsituted sample groups indicated significantly similar or higher values compared to those of control showing the possibilities of developments in health concerned funtional rice coopkies.

포도주 부산물이 퇴비와 혼합처리 시용에 따른 고추생육에 미치는 영향을 구명하기 위해 평창군 비가림재배 시설하우스 농가에서 수행하였다. 초기 생육기인 정식 후 15에는 고추의 초장은 유의차가 인정되지 않았으나 정식 후 기간이 경과함에 따라 높은 증가추세를 나타내었으며, 경경의 경우 정식 후 45일, 75일에는 유의차(p>0.05)가 인정되었다. 대조구(돈분발효퇴비 2,000kg/10a)가 0.53cm에서 1.67cm로 1.14cm 증가하였는데, 처리구 T4(포도주부산물 400kg＋돈분발효퇴비 1,000kg/10a)는 0.5cm에서 1.74cm로 1.24cm 증가하여 대조구에 비하여 8.7% 높은 증가율을 보였다. 각 처리구의 엽록소 함량은 45일에 증가하다가 75일에 다시 감소하는 현상을 나타내었으며, 처리 15일에서 T1(포도주부산물 200kg＋돈분발효퇴비 2,000kg/10a)과 대조구 사이에 유의차가 인정되었으며, T1(포도주부산물 200kg＋돈분발효퇴비 2,000kg/10a)이 대조구(돈분발효퇴비 2,000kg/10a)보다 2.6이 높은 56.1로서 가장 높았으며, T4(포도주부산물 400kg＋돈분발효퇴비 1,000kg/10a)에서는 53.4로 대조구와 같은 수준을 나타내었다. 엽면적은 정식 후 45일에서 T4(포도주부산물 400kg＋돈분발효퇴비 1,000kg/10a)가 60.0$\textrm{cm}^2$로 가장 높게 나타났다. 홍고추의 주당 수량은 돈분발효퇴비와 포도주부산물을 같이 시비한 처리구가 대조구(돈분발효퇴비 2,000kg/10a)에 비하여 감소현상을 보였는데 이러한 현상은 생육후반기에 암모니아 가스에 의해 작물의 피해가 발생하여 수량이 감소된 것으로 사료된다.
