본 연구의 목적은 차, 커피, 와인, 맥주의 스마트폰 앱들의 종류와 기능을 비교하고 기술수용모델을 적용하여 차연관 앱의 실제 사용도를 높일 수 있는 기능을 제시하고자 하였다. 애플앱스토어에서 검색된 200개의 차, 커피, 와인, 맥주 앱들의 기능을 살펴본 결과 차, 커피, 와인, 맥주 앱들의 기능은 17개 종류로 파악되었다. 차와 커피 앱들의 기능은 유의한 차이가 없는 것으로 나타났는데 차와 와인, 차와 맥주 앱들의 기능은 유의한 차이가 있었다(p<0.01). 차연관 앱들은 오락성 위주의 앱들이 높은 비율을 차지하고 있으며 와인 앱들은 와인에 관한 정보 찾기, 와인의 특성을 기록하는 노트, 주변 상점/카페 찾기 등 유용성 위주의 앱들의 비율이 차, 커피, 맥주에 비하여 더 높은 것으로 나타났다. 차와 연관된 앱들의 실제 사용도를 높이기 위하여 커피, 와인, 맥주 앱들의 기능을 사례로 제시하였다. 국내 차연관 앱의 개발을 위하여 제시된 기능을 차연관 앱의 메뉴로 구성하여 제시하였다.

PURPOSE. Beverages may affect the translucency of esthetic dental restorative materials.The aim of the present study was to investigate the effects of coffee and red wine on the translucency of a PICN material with two translucency levels, and finished with different methods. MATERIALS AND METHODS. 2M2 high translucent and translucent VITA Enamic hybrid ceramic blocks were investigated. Rectangular specimens with the dimensions of $12mm{\times}14mm{\times}2mm$ were prepared. The specimens were finished and polished with different methods as suggested by the manufacturer. The translucency parameters of the specimens were evaluated before and after 24 hours, 7 days, and 28 days immersion in distilled water, coffee and red wine. Translucency parameters were measured using a portable spectrophotometer. RESULTS. At the end of 28 days, there was no statistically significant difference between the groups of specimens kept in coffee (P>.05). In the red wine groups, there was a statistically significant difference between the control group and all other groups (P<.05) at the end of 28 days. CONCLUSION. The translucency of hybrid ceramic for a restoration may not be important regarding the effects of coffee on translucency change because the specimens with different translucencies and finishing methods that were immersed to coffee had similar translucency parameters at the end of 28 days. The translucency of hybrid ceramic may be important in the case of red wine, however, since the results showed that highly translucent specimens exposed to red wine demonstrated better translucency parameters than specimens made from translucent blocks at the end of 28 days.

본 연구에서는 고초균으로 발효된 브라질산 원두로 커피추출물을 제조하였으며, 효모 발효를 위한 혼합액(20% glucose, 1% yeast extract, 70% roasted coffee extract)에 Saccharomyces cerevisiae SRCM102539 균주를 접종한 후, 정치배양(30℃, 5일)하여 커피와인을 제조하였다. 커피식초는 Acetobacter pasteurianus CT_02 균주로 제조한 종초를 커피와인에 30%(v/v) 첨가하고, 진탕배양(30℃, 120 rpm, 15일)하였으며 발효기간 중 5일 간격으로 생균수, 이화학적 특성(수용성 고형분 함량, pH 및 총산도), 유기산, 유리당 및 에탄올 함량을 분석하였다. 초산균 발효 전(0일 차, AUFCW)과 후(15일 차, AFCW)의 생균수, 수용성 고형분 함량, pH 및 총산도의 변화는 각각 6.35 log CFU/mL에서 4.19 log CFU/mL, 8.10 °Brix에서 8.57 °Brix, 3.88에서 3.07 및 1.29%에서 7.45%로 나타났다. HPLC 분석을 통한 glucose의 함량은 발효기간에 따라 유의적인 차이가 없었으며, 에탄올 함량은 AUFCW에서 6.02%(w/v)였으나, AFCW에서는 검출되지 않았다. AFCW의 주요 유기산은 acetic acid(5,921.43 mg%), succinic acid(434.96 mg%)와 citric acid(69.43 mg%)로 3종이 검출되었다. 커피식초의 pancreatic lipase 저해활성은 발효기간이 경과함에 따라 증가하는 경향을 나타내었다. MDI로 지방분화가 유도된 3T3-L1 세포에 대한 AFCW의 항비만 효능평가를 지질축적률, 렙틴 단백질 발현량 및 지방 생성관련 유전자(PPAR-γ 및 SREBP-1c)의 mRNA 발현량 분석으로 진행하였다. AFCW의 항비만 효능은 200 ㎍/mL 농도 처리 시 MDI 단독 처리구 100%에 비해 지질축적률은 69.37%, 렙틴 단백질 함량은 50.20%로 감소하였으며, PPAR-γ 및 SREBP-1c의 mRNA 발현량은 각각 79.89% 및 48.81%로 감소하였다. 이러한 결과를 바탕으로 커피와 인으로 제조된 커피식초가 초산균의 발효과정을 통해 항비만 효능을 더 증가시켰음을 확인할 수 있었다.

In order to investigate the detergency of the mixture of compact detergent and bleaching agent to fabric stained with a coffee and a red wine, respectively, and a japanese wet stained fabrics, to evaluation of detergency was studied under various washing conditions. In order to study the effect of alkaline agent addition on the detergency, the soda ash was added in the compact detergent system. The results are as follows : In a low temperature washing condition, the alkalinity of washing liquor effected more the removal of the composite stained fabrics than that of oilic stained fabrics. For the colored stained fabric such as red wine stained sample, the influence of the repeated washing treatment on the detergency was not significant factor. On the other hand, the influence of the repeated washing treatment for the coffee stained and japanese wet stained fabric on the detergency was gradually increased.

Background: Temporary crown resins are used prior to prosthesis placement, indicating the importance of aesthetics. The aim of this study was evaluate the color stability of various staining solutions according to the color of temporary crown resins using VITA Easyshade^Ⓡ V. Methods: The temporary crowns used were the powder-liquid type and included four shades. A total of 36 specimens were fabricated in the form of disks with a diameter of 1.8 mm and a depth of 2 mm. They were divided into four groups of nine each, and staining was performed for seven days by precipitation in 3 mL of three staining solutions composed of distilled water, black coffee, and red wine. Color and color stability evaluations were performed by a trained examiner using a digital spectrophotometer (VITA Easyshade^Ⓡ V). Color stability was analyzed using the ΔE value. Results: Because of the color stability evaluation using the ΔE value, the difference between three and seven days was significant in the specimen I and III groups (p<0.05). Further, post hoc analysis showed that the ΔE value of red wine was significant, indicating that the color stability in red wine was low. The ΔE values in group II between days three and seven were statistically significant (p<0.05). Post hoc analysis showed that distilled water, coffee, and wine had the highest ΔE values on day three. On day seven, the ΔE value for wine was significant, and the color stability was low. There was no significant difference in group IV according to the staining period and staining solution; therefore, color stability was high (p>0.05). Conclusion: This study showed that most temporary resin restorations exhibited color stability in the staining solution. The darker the color of the temporary resin restoration, the higher the color stability against extrinsic staining.

Purpose - The purpose of this study is to determine consumers' awareness of hygiene and the perceived risks in the service areas of coffee shops and diners, or simply coffee shops. Research design, data, and methodology - A literature review was conducted on related publications, essays, and periodicals to find correlations among the variables. We developed a research model and hypothesis, and conducted empirical research for statistical data analysis. Results - The results satisfied adequacy standards, with GFI=0.926, AGFI=0.901, RMR=0.020, NFI=0.941, X²=403.197, and p-value=0.120. The results also displayed satisfied adequacy standards for the moderating effects of shop types, with GFI=0.998 (≥0.9 desirable), AGFI=0.998 (≥0.9 desirable), RMR=0.004 (≤0.05 desirable), NFI=0.999 (≥0.9 desirable), X²=1.572, and p-value=0.814 (≥0.05 desirable). Conclusions - A higher consumer hygienic awareness results in a better brand image. Moreover, greater perceived risk results in a worse brand image. Perceived risk is a vital determinant of brand image and it deeply influences customers' decisions to visit. Therefore, perceived risk is a vital determinant of forming a brand image and must be incorporated when devising strategies.
