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.

Objectives: This study aimed to: 1) investigate the beverage consumption pattern among Korean adults, and 2) analyze the relationship between the frequency of beverage consumption and oral health status. Methods: We used data from the 6th Korean National Health and Nutrition Examination Survey. A general linear model was employed to assess the associations between demographic factors and frequency of beverage consumption; and oral health status and the frequency of beverage consumption. Results: The beverage with the highest frequency of intake was coffee (11.5 times per week). More frequent consumptions of fruit juices and carbonated drinks were associated with higher numbers of decayed teeth. Conclusions: To improve oral health, frequent intake of acidic and sweetened beverages should be reduced, and the consumption of milk should be encouraged.

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.

A powdered beverage with afruit flavor was stored at 4, 21, 35 and $45^{\circ}C$ for 180 days to study ascerbic acid destruction at the selected temperatures. Degradation of ascorbic acid in the model followed the first order reaction, and the temperature dependence of reaction rate constants at tested temperatures was accounted for by the Arrhenius equqtion. The calculated activation energy for the destruction of ascorbic acid was 3.3 Kcal/mole. The relationship between ascorbic acid content and sensory flavor score of the beverage indicated that samples with destruction of ascorbic acid over 25% showed objectionable flavor. An attempt was made to predict the quality of powdered beverage by using a simulation model. A comparision between ascorbic acid values from shelflife tests and the simulation program showed a good agreement within acceptable error. This result demonstrated that quality of powdered beverage could be predicted by using a computer simulation model with a desired accuracy.

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.
