정보통신기술의 급속한 발달과 더불어 인터넷이 널리 사용되게 되고, 인터넷을 통한 음성과 데이터를 통합한 서비스 사업이 크게 확산되어 가고 있다. 이에 따라 IP망에서 전송되는 음성의 품질은 현재 상용화되고 있는 VoIP의 대중화를 위해서 가장 시급히 해결되어야 할 문제이다. 본 연구에서는 IP망에서 전송되는 음성의 품질에 영향을 미치는 요소들과 음성품질 측정 방법을 분석하고, 차세대 네트워크에서 사용될 VoIP의 음성품질을 측정할 수 있는 측정방식을 제안 및 구현하였다. 제안된 방식을 이용하여 VoIP에서 음성품질을 측정한 결과, 음성품질은 코덱과 인터넷서 버스방식에 따라 달라지는 것으로 분석된다. Due to the rapid growth of the Internet, voice and data integrated service over Internet Protocol(IP) network is growing very fast. In order to popularize the commercialized IP telephony service, voice transmission quality through IP network must be enhanced. In this paper, we analyze various elements that interfere the voice transmission quality over the IP network and propose the measurement scheme that can measure voice quality over the IP network effectively. Using proposed scheme, we implement the scheme and measure the voice quality of VoIP. The result show voice quality is influenced by codec and internet service method.

Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) is a pivotal regulator of low lipoprotein-cholesterol (LDL-C) metabolism, and the interest in PCSK9 has increased in cardiovascular diseases. PURPOSE: Exercise reduces blood LDL-C via PCSK9-LDLR pathway in liver. However, the mechanism of exercise-induced inhibition of PCSK is not unclear. The aim of this review is to describe the role of exercise on PCSK9-LDLR axis in cardiovascular diseases. METHODS: This study reviews 34 previous studies focusing on the effect on exercise on PCSK9 in the human and animal. RESULTS: The effects of exercise and lifestyle intervention on hepatic and circulating PCSK9 are controversial. However, exercise consistently increases hepatic LDLR, and inhibits atherosclerosis via suppression of PCSK9 and LOX-1 in atherosclerotic region. CONCLUSIONS: Even though experimental data are still very limited, exercise training can improves blood LDL-C via inhibition of PCSK9 and enhancement of LDLR in liver and vasculature. The study of exercise on PCSK9 are urgently needed.

PURPOSE: Perivascular adipose tissue (PVAT) is a type of adipose tissue that surrounds vessels to provide anti-contractile effects. This study aimed to investigate the effect of resistance training on NADPH oxidase, adiponectin, and endothelial NOS (eNOS) expression in the abdominal aorta and PVAT of ovariectomized rats. METHODS: Sprague-Dawley rats at 20 weeks of age were divided into three groups: sham control (Sham, n=10), OVX-control (OVX_ Con, n=10), and OVX-resistance exercise (OVX_Rex, n=10). Resistance training was performed by climbing a ladder for 12 weeks. Western blotting was used to analyze target protein expression in the rat abdominal aorta and PVAT. RESULTS: NADPH oxidase (p67phox) expression was significantly higher in the OVX_Con group than in the sham group, but it was significantly decreased in the OVX_Rex group. The expression of adiponectin, AKT, and eNOS in both abdominal aorta and PVAT was significantly reduced in the OVX_Con group than in the Sham group, but it was improved in the OVX_Rex group. CONCLUSIONS: The results suggest that regular resistance training inhibits p67phox and increases adiponectin expression and phosphorylation of AKT and eNOS in abdominal aortic PVAT of ovariectomized rats.
