  • Recently, deep learning has been used in the development of various institutional devices and services to help the visually impaired people in their daily lives. This is because not only are there few products and facility guides written in braille, but less than 10% of the visually impaired can use braille. In this paper, we propose a system that recognizes beverage cans in real time and outputs the beverage can name with sound for the convenience of the visually impaired. Five commercially available beverage cans were selected, and a CNN model and a YOLO model were designed to recognize the beverage cans. After augmenting the image data, model training was performed. The accuracy of the proposed CNN model and YOLO model is 91.2% and 90.8%, respectively. For practical verification, a system was built by attaching a camera and speaker to a Raspberry Pi. In the system, the YOLO model was applied. It was confirmed that beverage cans were recognized and output as sound in real time in various environments.

  • The purpose of this study was to understand the influence of employees' commitment (affective, normative, continuous) in the food & beverage departments of deluxe hotels upon job satisfaction and analyze the moderating effects of the leader-member exchange on the relationship between organizational commitment and job satisfaction. Based on a total of 403 food & beverage employees, this study reviewed the reliability and fitness of the research model and verified two hypotheses. The hypothesized relationships in the model were tested simultaneously by using SEM. The proposed model provided an adequate fit to the data, ${\chi}^2=635.160$ (p< .001), df=112, GFI= .845, NFI= .851, CFI= .874. SEM showed that organizational commitment (affective: ${\beta}=428$; normative: ${\beta}= .293$; continuous: ${\beta}= .342$) showed a positive significant influence on job satisfaction. However, the findings demonstrate that the leader-member exchange did not moderate the relationship between organizational commitment and job satisfaction. Limitations and future research directions are also discussed.

  • 오렌지향을 갖는 분말음료의 모델시스템을 설정하여 각기 $4^{\circ}$, $21^{\circ}$, $35^{\circ}$, $45^{\circ}$, C에서 약 180일간 저장하여 아스코르빈산의 파괴를 측정하였다. 본 모델시스템에서 아스코르빈산의 파괴는 1차 반응이었으며 반응속도에 대한 온도와의 관계는 Arrhenius식에 따랐다. 아스코르빈산의 파괴에 대한 활성화 에너지는 3.3 Kcal/mole 이었으며 아스코르빈산의 잔존량과 향미 평점간의 상관관계에서 25% 이상 파괴되면 이미를 느낄 수 있었다. Simulation 모델을 적용하여 분말음료의 품질을 예견한바, 저장시험의 결과와 Simulation간의 오차는 약 3% 이내로 매우 만족스러웠다. 이러한 결과로 분말음료의 품질을 Simulation을 이용하여 예견할 수 있음으로 보여주었다.

  • To produce an intestinal immunomodulatory beverage containing Centella asiatica extract (CAE), three types of CAE-added beverage prototypes were prepared, and their immunomodulatory activities and marker compounds were analyzed. As a result of the cytotoxicity assessment, all the beverages did not show significant toxicity compared to the control group. Next, the immunomodulatory activities of the beverage prototype were evaluated using the inflammatory model of IL-1β-induced intestinal epithelial cell line. All the samples significantly reduced the production of IL-6, IL-8, and MCP-1 in a CAE concentration-dependent manner. In addition, CAE-added beverages inhibited NO, IL-6, and IL-12 production in LPS-induced RAW 264.7 cells. When the major triterpenoids, as marker compounds for the production of CAE-added beverages, were analyzed by HPLC-DAD, only asiaticoside was detected beyond the limit of quantification, while madecassoside, madecassic acid, and asiatic acid were not detected. The amounts of asiaticoside in CAE-added beverage prototypes were confirmed in No. 1 (19.39 ㎍/mL), 2 (19.25 ㎍/mL), and 3 (19.98 ㎍/mL). In conclusion, the results of this study suggested that CAE-added beverage prototypes induced immunomodulatory effects in the intestinal inflammatory cell line models and asiaticoside could be used as a marker compound for CAE-added beverage production.
