In this study, the effect of added cashew nuts on the quality characteristics of pound cake were investigated. The weight and volume of the cake increased with the addition of cashew nuts concentration, whereas the dough yield and baking loss decreased. Furthermore, the hardness, penetration and, degree of retrogradation significantly decreased during storage with the addition of cashew nuts. As the cashew concentration was increased, the lightness and redness values of the crumb decreased and the yellowness values increased. In terms of sensory evaluation, when compared to the control group, the cashew nuts pound cake was superior in taste, flavor, chewiness and overall acceptability.

This study investigated the quality characteristics of sponge cake by introduction of buckwheat powder (BP). Cake batter was prepared by substituting wheat flour with an equivalent amount of BP based on weight. Sponge cakes were prepared with different amounts of BP (0, 10, 20, and 30%, respectively). Their physicochemical and sensory properties were tested. The specific gravity was not affected by the addition of BP (10~30%) (p<0.05). The lightness (L value) and yellowness (b value) of the crumb significantly decreased with the increase in the BP contents (p<0.05), whereas the redness (a value) increased (p<0.05). As the increase in the amount of BP addition, the hardness, cake volume (mL), baking loss rate (%), and specific volume (mL/g) significantly decreased (p<0.05). On the contrary, the cake weight increased. In the sensory evaluation, no significant differences in terms of color, taste, texture, flavor, and overall acceptance were observed among the different amout of BP addition (0~20%) (p<0.05). Overall, the sponge cake prepared with the addition of 20% BP was recommended to use due to its advantages in functional property.

Effect of different levels (0 ,0.05, 0.15, 0.25%) of xanthan gum on kakdugi fermentation was investigated by analyzing physicochemical and sensory characteristics during fermentation at 2$0^{\circ}C$. During fermentation, pH was maintained higher, and total acidity and number of lactic acid bacteria, maintained lower in xanthan gum groups, especially in 0.05% addition group than control. Free sugar amount were higher in xanthan gun groups than control, and glucose and fructose which were the major free sugars, decreased rapidly during fermentation, whereas mannitol increased in all samples, especially in xanthan gum groups. Liquid content of kakdugi was smaller in 0.05% xanthan gum group than control. Viscosity of kakdugi liquid decreased rapidly whereas initial viscosity was maintained in xanthan gum groups. Hardness decreased during fermentation, but at the 7th day of fermentation was higher in 0.05% xanthan gum group than control. The result of sensory evaluation shows that there were no significant difference in sour odor, moldy, sour taste and savory taste among samples. Starch taste was higher in 0.15% or 0.25% xanthan gum, but there is no difference in 0.05% group, compared to control. Overall preference until the 5th day of fermentation, xanthan gum group was not significantly different from that of control but at the 7th day of fermentation, 0.05% addition group was significantly higher than control.

TMR (total mixed ration) feed was developed by adding mugwort (Artemisia capillaris Thunb.) and was fed to Hanwoo cattle. We investigated the effects of feeding mugwort on the physicochemical properties and sensory scores of the Hanwoo beef, as well as the feasibility of producing beef with high quality and function. Samples included Hanwoo loin fed with fattening cattle TMR feed with (treatment) or without mugwort (control). The content of total catechin in Hanwoo loin fed with the treatment and control was 0.516 and 0.307 mg/kg, respectively, while the content of epicatechin was 0.116 and 0.087 mg/kg, respectively, both of which were significant increase from feeding TMR with mugwort (p<0.05). There was no significant difference between the control and treatment in terms of $b^*$ value, VBN content, EDA, total bacterial numbers, freezing loss, thawing loss, cooking loss, hardness, cohesiveness, gumminess, chewiness, shear force, or sensory score of boiled meat. $L^*$, $a^*$ and pH value for the treatment were significantly higher than the control (p<0.05). TBARS and springiness for the control were significantly higher than the treatment (p<0.05). The aroma of the raw meat and the taste, tenderness, juiciness, and palatability of the roasted meat for the treatment were significantly superior to the control (p<0.05). These results suggest that giving feed containing mugwort inhibits lipid oxidation, increases water holding capacity, and improve sensory scores.

사전학습 언어모델을 개선하여 고품질의 문장 표현(sentence representation)을 도출하기 위한 다양한 대조 학습 방법에 대한 연구가 진행되고 있다. 그러나, 대부분의 대조학습 방법들은 문장 쌍의 관계만을 고려하며, 문장 간의 유사 정도를 파악하는데는 한계가 있어서 근본적인 대조 학습 목표를 저해하였다. 이에 최근 삼중항 손실 (triplet loss) 함수를 도입하여 문장의 상대적 유사성을 파악하여 대조학습의 성능을 개선한 연구들이 제안되었다. 그러나 많은 연구들이 영어를 기반으로한 사전학습 언어모델을 대상으로 하였으며, 한국어 기반의 비지도 대조학습에 대한 삼중항 손실 함수의 실효성 검증 및 분석은 여전히 부족한 실정이다. 본 논문에서는 이러한 방법론이 한국어 비지도 대조학습에서도 유효한지 면밀히 검증하였으며, 다양한 평가 지표를 통해 해당 방법론의 타당성을 확인하였다. 본 논문의 결과가 향후 한국어 문장 표현 연구 발전에 기여하기를 기대한다.

다슬기분말(PSB)과 그 회분(ASB)으로 제조한 칼슘락테이트(PCaL 및 ACaL)를 0.5%씩 첨가한 반죽의 발효와 빵의 품질 및 저장성에 미치는 영향을 조사하였다. 반죽의 pH는 4.85~4.98로 ACaL.PCaL.대조군의 순으로 나타났다. 반죽의 부피와 빵의 loaf volume index는 대조군이 높았고 ACaL 첨가군이 낮았으며, pH를 5.50으로 조정하여 제조한 반죽의 부피와 빵의 loaf volume은 대조군과 큰 차이를 보이지 않았다. PCaL 및 ACaL을 첨가한 빵의 Ca함량은 29.4~29.7 mg/100 g-f.w로 대조군의 13.0 mg/100 g-f.w에 비하여 높았으며, 첨가군의 미량 무기질로 Mg, Fe, Zn이 0.03~0.98 mg/100 g-f.w 범위로 검출되었다. 빵의 L$^{*}$ 값은 대조군과 실험군의 유의적인 차이가 없었으며, a＊값, b＊값은 PCaL 첨가군이 가장 높아 황갈색을 띄었다. 빵의 hardness, gumminess는 대조군$^{\circ}C$ 실온에 두면서 저장한 결과 대조군은 3일째부터, ACaL 첨가군은 5일째부터, PCaL 첨가군은 6일째부터 곰팡이가 번식하였다.

The effects of olive oil addition on the quality characteristics of pound cake was investigated. Olive oil was added to the batter at a ratio of 33, 66 and 100%. The volume of pound cake prepared by adding $33{\sim}100%$ olive oil increased from 841.2 to 1083.2 mL. The volume index of pound cake prepared by adding $33{\sim}100%$ olive oil increased by $3.19{\sim}3.70$ and that of the control was 2.88. The hardness and penetration resulting from the addition of $33{\sim}100%$ olive oil decreased significantly during storage for 1 hour and 72 hours, respectively. The lightness and redness values of the cake decreased with increasing olive oil content. The taste, moistness and overall acceptability of the pound cake with 66% olive oil were the best.

This study was carried out to evaluate the effects of buckwheat powder on bread quality. Different breads were prepared with additions of 0%, 15%, 30%, and 45% buckwheat powder in place of wheat flour. The weights of the breads with buckwheat powder were in the range of 430.3 - 441.5 g, and the control was 421.3g. The volumes of the breads prepared with 15%, 30%, and 45% buckwheat powder were 2432.3 mL, 2219.3 mL, and 2090.8 mL, respectively. The water absorption rates of the breads with added buckwheat powder increased with the addition of buckwheat powder. Hardness increased with the addition of buckwheat powder, and was highest for the bread made with 45% buckwheat powder. The overall sensory quality of the buckwheat powder bread, which was tested by color and taste, was better than that of the control; specifically, the quality of the 30% buckwheat powder bread was the best.

난황형성기의 난소를 가진 암컷 어미에게 갑상선 호르몬인 3,5,3'-triiodo-L-thyronine ($T_{3}$)를 20 mg $T_{3}$/kg체중으로 주사하여 출산된 조피볼락 자어를 대조구 자어와 함께 30일간 사육하면서 성장과 생존율을 비교하였고, 실험종료시인 전어체를 갈아 체성분 조성을 파악하였다. 출산자어의 성장은 대조구에 비해 $T_{3}$구에서 유의하게 빨랐으며, 생존율 역시 $T_{3}$구가 대조구보다 유의하게 높았다. 실험종료시 치어의 비만도는 대조구가 $T_{3}$구에 비해 높게 나타났다. 실험종료시 $T_{3}$구의 어체내 수분과 회분함량은 대조구의 결과와 유의한 차이를 보이지 않았으나, 단백질 함량은 $T_{3}$구에서 대조구 보다 높았으며, 지질은 $T_{3}$에서 오히려 낮았다. 이상의 결과로 조피볼락에 대한 $T_{3}$의 모체주사는 출산자어의 성장과 생존율 향상에 도움을 주는 것으로 평가되었다.
