The health of modern people is threatened by bad eating habits. In order to provide healthy desserts to people, we conducted a study on adding plum concentrate, which is effective for fatigue recovery, insomnia, and prevention of constipation, to scones. In order to examine the utility of scones made by adding plum concentrate, the following experiment was conducted. It was prepared by adding 0g, 3g, 5g, and 7g of plum concentrate to the scone dough, respectively. As a result of the test, the sensory characteristic value was the highest in the experimental group to which 5 g of plum concentrate was added (4.77). There was a significant difference in that the average value tended to increase as the concentration of the plum concentrate increased. As for fragrance, the experimental group with the addition of 5 g of plum concentrate showed the highest sensory characteristic value of 3.62, but there was no significant difference. The experimental group to which 3 g of plum concentrate was added showed higher preference than the control group in most items such as color, flavor, sweetness, and overall preference. This study suggests that the production of scones with plum concentrate has a high potential for commercial use.

Jeolpyon rice cake was made using buckwheat flour and measured its texture, color and sensory properties as follows. According to the amylograph guage test, rice flour was the highest in its initial pasting temperature $82.5^{\circ}C$. With 5% addition of buckwheat flour, it came to be $81.0^{\circ}C$ and became $79.5^{\circ}C$ at 10%, and $78.0^{\circ}C$ at 15%, which was lower than the control. And its maximum temperature at peak viscosity showed at $87^{\circ}C$ and it showed no difference in temperature according to the amount of buckwheat flour. The maximum value (peak point) was 690 BU in control and it increased following to the added amount of buckwheat flour, 710 BU in adding buckwheat flour 10% and 740 BU in 15% of buckwheat flour. In relating to the changes of texture, it became hard by the added amount of buckwheat flour because of decreasing cohesiveness and springiness, but increasing gumminess and brittleness. The hardness increased by adding with buckwheat flour through the freeze preserving period. But adding buckwheat flour of 10% decreased the hardness. Regarding the color value, lightness decreased by the adding buckwheat flour, but a and b value increased. As a result of the sensory analysis about Jeolpyon prepared with buckwheat flour, the most favoured ratio of buckwheat flour for color and preference was at 10%. In case of 15%, it was a little dark so it was not desirable. Based on the above test, the best combination ratio of buckwheat for Jeolpyon was 10%. And Jeolpyon can be easily made at home as well as mass production due to relatively simple making procedure.

This study was conducted to investigate the effects of adding gochujang addition to cookie dough on the quality characteristics of cookies. Cookies were prepared by replacing 0% 5%, 10%, 15% and 20% flour with gochujang. The gochujang pH, total soluble solid and salinity were $4.84{\pm}0.02$, $63.33{\pm}4.19%$ and $7.63{\pm}009%$, respectively. The moisture content in gochujang was $40.10{\pm}0.10%$, and the color values of gochujang was were as L-value $24.46{\pm}0.06$, a-value $10.18{\pm}0.13$, and b-value $7.44{\pm}0.10$. The pH values of cookies decreased according to the addition of gochujang. The values of density and loss rate in cookies were not-significantly different among the samples. Spread factor and moisture content of cookies increased with amounts of added gochujang. The salinity and total soluble solid content of cookies with gochujang were significantly higher than those of the control. L-value was significantly reduced, and a-value and b-value increased by adding gochujang. Total phenolic content and DPPH free radical scavenging activities were increased according to the amount of gochujang. For sensory evaluation, gochujang added cookies were more preferred in terms of color, softness and overall preference. Overall, these results indicate that adding 10% gochujang is desirable for making gochujang cookies.

The purpose of this study was to investigate the effects of the addition of various concentrations of antler powder on the physicochemical and sensory characteristics of mango jelly As for pH and viscosity of the mango jelly, antler powder added group showed higher pH and viscosity than that of control group. As for turbidity, absorbance increased significantly(p<.001) by the addition of antler while permeability decreased. The syneresis increased with the passage of time. According to sensory evaluation, Sleekness showed the highest by adding $0.2\%$ antler powder in mango jelly. The hunter color L and b value decreased significantly(p<.001) by adding antler powder. The mechanical properties such as hardness, springiness, cohesiveness and brittleness were highest by adding $1.0\%$ antler powder while gumminess was highest by adding $0.2\%$ antler powder in mango jelly. Overall quality, taste, appearance, texture were most superior by adding $0.2\%$ antler powder in mango jelly. From these test results, the optimum recipe for mango jelly added with antler powder was $0.2\%$ of antler powder, $10\%$ sugar, $\2%$ agar and 351.2ml of mango juice.

벤처캐피탈과 신생 기업의 투자 관계를 다룬 기존 연구는 주로 투자자인 벤처캐피탈의 입장에서 스타트업을 선택하는데 초점을 맞추었다. 하지만 최근 벤처캐피탈 사이의 경쟁이 높아짐에 따라 기술력이 검증된 우수한 스타트업의 경우 역으로 벤처캐피탈을 선택하는 현상이 나타나고 있다. 본 연구는 스타트업이 벤처캐피탈을 선택할 경우, 벤처캐피탈과 관련된 어떤 요소가 선택에 영향을 미쳤는지 살펴보았다. 이를 위해 복수의 벤처캐피탈로부터 동시에 투자제의를 받은 경험이 있는 국내 스타트업을 대상으로 어떤 벤처캐피탈 회사를 최종 투자자로 택했는지 살펴보았다. 창업 초기단계(Pre-series A/Series A) 창업가 6명, 중기단계(Series B/C) 창업가 5명을 인터뷰하여 벤처캐피탈의 세 가지 요소: 1) 벤처캐피탈 명성(reputation), 2) 창업자와 투자자와의 관계(Relationship), 3) 벤처캐피탈이 제공하는 가치 증대 활동(Value adding service)이 선택에 미치는 영향력을 중심으로 연구하였다. 연구결과, 벤처캐피탈의 명성 중 투자포트폴리오는 매우 중요한 벤처캐피탈의 선정 기준이 되였다. 하지만, 벤처캐피탈의 운용기간과 펀드 운용액은 중요하지 않은 것으로 나타났다. 관계는 매우 중요한 요소로 나타났다. 마지막으로 벤처캐피탈의 가치 증대 활동에 대해서는 본 연구의 스타트업 창업자들은 중요하게 생각하지 않았다. 특히, 벤처캐피탈의 컨설팅과 모니터링은 오히려 스타트업에게 부담을 주는 요소로 작용했다. 본 연구는 투자 경쟁이 치열한 투자시장에서 벤처캐피탈의 투자 성공 확률을 높여주고, 벤처캐피탈과 스타트업 간의 상호 이해를 증진시켜 줄 수 있는 시사점을 제시한다.

This study is a theoretical exploration of project-based service-learning and its application in designing pre-dental curricula. As a response to the limitation of community service courses, service-learning has been implemented as pedagogy in higher education practices. Service-learning connects service and learning by engaging students in activities that address community needs with intentionally designed learning opportunities while adding value to and transforming both service and learning. Project-based service-learning is an extended and more active version of service-learning. Whereas service activities are arranged by instructors in the original service-learning, project-based service-learning provides students with opportunities for exploring problems and root causes on site and then devising and implementing solutions of their own using their talents and creativity. This study proposes a theoretical approach to project-based service-learning and suggests six design components, namely, related curriculum, reflection, reciprocity, service and community engagement, evaluation and recognition, and creative problem solving. Based on the components, 20 design strategies are formulated. The exploration is aimed to provide design guides for professionals attempting to implement project-based service-learning in higher education.

This study was preformed to make high quality fish cake made with silver pomfret, which is one of the savory, soft and delicious fishes by adding wasabi powder (WP). WP as natural additives was added to the ratio of 0.6%, 1.2%, 1.8%, 2.4%, 3%, a color values, texture, folding test, sensory evaluation, peroxide value, TBA value, and viable cell count were analyzed. L and a value were decreased significantly by the increase of the ratio of WP. However, b value was increased. In the folding test to show the flexibility of fish cake, it was measured AA in the all samples. As the result of measuring texture, hardness was increased significantly by the addition of WP, cohesiveness was the highest in 1.8 WP and 0.6 WP, Springiness showed no significant difference among samples. However gumminess and chewiness of fish cake adding wasabi powder were significantly higher comparing with control group. In sensory evaluation, 1.8 WP had the best score in overall acceptability. Fish cakes had lower peroxide value, TBA value and viable cell count after frying compared to the one without WP. These results indicate that fish cake could be prepared by adding the WP for high quality and functionality. Consequently, wasabi can be applied as a food preservative or additive in fish cake.
