최근 스마트 홈에서 슬립테크를 제어할 수 있는 어플리케이션 개발 및 연구의 필요성이 높아지고 있다. 기존 스마트 홈 제어 어플리케이션들은 텍스트 형식의 UI, 직관적인 정보 제공의 부재, 스마트 스위치 수준의 서비스 제공 등의 문제점을 가지고 있다. 이러한 문제점을 개선하기 위해 본 논문에서는 증강현실과 3D 모델링을 통해 스마트 홈을 보다 직관적이고 편리하게 사용할 수 있는 슬립테크 제어 방법을 제안한다.

This study investigated the potential for using vegetable powders as a natural replacement for sodium nitrite and their effects on the physicochemical characteristics of alternatively cured pork products. We analyzed pork products subjected to four treatments: control (0.015% sodium nitrite), Chinese cabbabe powder (CCP) treatment (0.4% Chinese cabbage powder), radish powder (RP) treatment (0.4% radish powder), and spinach powder (SP) treatment (0.4% spinach powder). Among the vegetable powders prepared in this study, SP had the highest (p<0.05) nitrate content, while CCP had the lowest (p<0.05). The cooking yields from these treatments were not significantly different from each other. However, the products with vegetable powders had higher (p<0.05) pH and thiobarbituric acid reactive substances values than the control. Pork products with vegetable powders also showed lower CIE L* values and higher CIE b* values than the nitrite-added control. RP treatment had similar (p>0.05) CIE a* values to the control, while SP treatment had the lowest (p<0.05) CIE a* values. The residual nitrite content was lower (p<0.05) in the vegetable powder added pork products than in the control, although nitrosyl hemochrome and total pigment contents in the CCP and RP treatments were similar (p>0.05) to those in the control. The control, CCP, and RP treatments showed curing efficiencies greater than 80%, indicating that CCP and RP would be promising potential replacements for sodium nitrite. The results of this study suggest that RP may be a suitable natural replacement for sodium nitrite to produce alternatively cured meat products, compared to other leafy vegetable powders.

In order to establish the most effective toothbrushing method, five women in their twenties who maintain a healthy oral condition brushed their teeth using a rolling tooth brushing method, scrub tooth brushing method, and tooth brushing using a sonic vibration electric toothbrush. Samples were taken from the tooth surface to compare the changes in Streptococcus mutans , Lactobacillus casei , general oral microorganisms, and dental plaque. Results were as follows. 1. S. mutans and L. casei on the tooth surface were most abundant following employment of the scrub tooth brushing method; lowest after using the rolling tooth brushing method; and low after brushing with a sonic vibration electric toothbrush. Therefore, the most effective tooth brushing method for the removal of S. mutans and L. casei was confirmed as the roll method. 2. As a result of comparing the changes of oral microorganisms on the surface of the teeth, the tooth brushing method which can be said to most effectively remove general oral microorganisms is the rolling tooth brushing method. Use of a sonic vibration electric toothbrush also had a large effect on removing general oral microorganisms. 3. Using the O’Leary index, the most effective tooth brushing method in reducing dental plaque is the rolling tooth brushing method. The scrub tooth brushing method was found to be less effective in removing dental plaque than the rolling tooth brushing method and tooth brushing method using a sonic vibration electric toothbrush.
