In this paper, a real-time control system with Wi-Fi wireless communication was developed for dentistry Integrated Device. The control system is developed based on the Android platform using S3C6410 ARM core that is equipped with Wi-Fi communication, RS-485, Linux 2.6 and Android 2.0. The control system controls a water purifier, compressor and suction in real-time. The experimental results that the control system was controlled by each control modules connected with a water purifier, compressor and suction. The status values are displayed in real-time using RS485.

Lactic acid bacteria (LAB) isolated from kimchi (a traditional Korean dish typically made of fermented cabbage) can provide various health benefits, including anti-obesity, antioxidant, antiinflammatory, anticancer, and antimicrobial effects. In this study, we examined the antimicrobial and immunomodulatory effects of Lactiplantibacillus plantarum WiKim0125 cultured in de Man, Rogosa, and Sharpe (MRS) medium containing vegetable waste. Live bacterial cells were eliminated via supernatant filtration or heat treatment. The cell-free supernatant (CFS) obtained from culture broth containing kimchi cabbage waste (KCW), cabbage waste (CW), or onion waste (OW) showed significantly higher antimicrobial activity against skin pathogens (Propionibacterium acnes and Staphylococcus aureus) and foodborne pathogens (Escherichia coli and Salmonella typhimurium), with inhibition zones ranging between 4.4 and 8.5 mm, compared to that in conventional MRS medium (4.0-7.3 mm). In lipopolysaccharide-stimulated RAW264.7 cells, both supernatant and heat-inactivated Lb. plantarum WiKim0125 from culture media containing KCW and CW suppressed the production of inflammatory cytokines (72.8% and 49.6%, respectively) and nitric oxide (62.2% and 66.7%, respectively) without affecting cell viability. These results indicate that vegetable waste can potentially increase the antimicrobial and immunoregulatory potency of LAB while presenting a molecular basis for applying postbiotics to health products.

Hae Ron(海論) was recorded to Tae So(太素)‘s volume 5 Sa-hae-hap(四海合), Gap Eul(甲乙)’s volume 1 chapter 8 Sahae(四海) and You Gyeong(類經)‘s volume 9 Gyung-lak-ryu-sam-sib-yi(經絡類三十二) Yin-ji-sa-hae(人之四海). Human body has the Sahae(四海; Gi hae, Heul hae, Sugok hae, Su hae) as like as Earth has Sahae(四海; East sea, West sea, South sea, North sea). Person's Sahae corresponds with Earth's Sahae. This chapter is explaining about Acupoint's position that Sahae's Gi-hyeol 氣血) comes in and go out, symptoms of disease, that can appear When Sahae lost homeostasis and the treatment principle, Yeong-wi-gi-hyeo(營衛氣血) enables complex vital phenomenon of human body. This Yeong-wi-gi-hyeo(營衛氣血) can not move if there is no systematic O-jang yuk-bu(五臟六腑), Sip-yi-gyeong-maek (十二經脈)) and Gi-gyeong-pal-maek (奇經八脈). For these system batch, it is Sahae do most important part. Sahae is synthetic and systematic concept. This chapter is explaining the position and function. Together, This chapter is presenting symptoms and treatment principle that can appear when Sahae overbalanced. This is offering important clue in Korean medicine physiology and pathology phenomeno study. Therefore, I gathers and compares and analyzed commentese of several doctors to grasp difinitely this chapter's contents, and also investigated and translated.

An authentication between a user's terminal and a Access Control Router (ACR) is preceded so that a user receives secure WiBro services. Otherwise they can be exposed from many attack risks. So the Telecommunications Technology Association (TTA) constituted a mechanism of the mutual authentication for WiBro service. In mechanism a user executes the mutual authentication between a Portable Equipment (PE) and the ACR by using Portable Internet Subscriber Identity Module (PISIM). But this standard needs many message to authenticate the ACR and the users cann't use wireless Internet service. Therefore in this paper we propose the key agreement protocol between the PSS and the ACR to authenticate the PSS to ACR. At this time Power Support Device (PSD) fer supporting the calculated quantity of the PSS is participated in the key agreement protocol. The ACR sends a generated key to Key Authentication Server (KAS) via secure IPsec tunnel and then it preserves the identity of the PSS and the value of key after it enciphered them. In conclusion we analyze the security and efficiency of the proposed protocol.

Accurately measuring location is necessary to provide a variety of services. The data for indoor positioning measures the RSSI values from the WiFi device through an application of a smartphone. The measured data becomes the raw data of machine learning. The feature data is the measured RSSI value, and the label is the name of the space for the measured position. For this purpose, the machine learning technique is to study a technique that predicts the exact location only with the WiFi signal by applying an efficient technique to classification. Ensemble is a technique for obtaining more accurate predictions through various models than one model, including backing and boosting. Among them, Boosting is a technique for adjusting the weight of a model through a modeling result based on sampled data, and there are various algorithms. This study uses Xgboost among the above techniques and evaluates performance with other ensemble techniques.
