Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

We use the survey results to analyse residents satisfaction level depending on three different public housing types such as public rental housing, sales after five years of initial lease and pre-sales apartments. Our findings can not only be used to improve the quality of housing service for low- and moderate income households but also to rationalize current government public housing project, that is, “Bogeumjari housing” and to optimize public budgetary expenses. Firstly, the residents of public rental housing prefer to have more community oriented facility due to eligibility standards such as age and limitations on car ownership. Secondly, pre-sales apartments residents, mostly owners, prefer to have better appearance which is essential to resale price and their satisfaction levels were relatively low. That is because they tend to compare their apartment with private dwellings once having lived in. Lastly, differing from our common sense, the residents living in sales after five years of initial lease apartments seem to behave more like those people in rental housing.

Objectives: The purpose of this study is to evaluate the effect of muscle releasing stimulation technique on low back pain. Methods: This study was carried out on the 50 patients who had low back pain. We treated the patients with muscle releasing stimulation technique, and evaluated by Visual Analogue Scale(VAS) and Range of Motion(R.O.M.) before and after the technique. We classified the patients according to sex and age, the motive of disease, the period of disease and the severity of disease. And we also campared each result of these conditions with the therapeutic result. Results: The period of disease is statistically related to the therapeutic result, but there was no significant function between sex and age, the motive of disease, the severity of disease and the therapeutic result. Low back pain was statistically improved by muscle releasing stimulation technique, and VAS was also statistically improved, especially ‘the acutest`, but it had no efficacy on ‘the chronic`. Conclusions: In the study, muscle releasing stimulation technique was effective on low back pain, especially ‘the acutest`, but not on ‘the chronic`.
신규 참여자의 형평성 향상을 위한 블록체인에서의 새로운 증명 방식 연구: Proof-of-Probability

최근 블록체인 기술을 응용한 가상화폐에 대한 관심이 높아지면서 자본금이 많지 않은 사람들도 블록체인 네트워크에 참여하기 시작했다. 가장 유명한 가상화폐인 비트코인이 채택한 PoW 방식은 고성능 하드웨어의 과열된 열풍을 불어왔고 PoS 방식은 기존 지분이 많은 참여자들이 많이 존재하여 소수의 자본금을 가진 신규 참여자들이 네트워크에 새로 참여하기 어려운 환경이다. 따라서 본 논문에서는 기존 블록체인 증명방식인 PoW, PoS 방식보다 네트워크 참여를 위한 자본금이 적고 신규로 참여하더라도 리스크가 적은 PoP(Proof-of-Probability) 방식을 소개한다. PoP 방식은 블록을 생성할 시 실제 암호화된 해쉬와 수많은 가짜 해쉬를 각 노드들이 정렬하여 진짜 해쉬를 복호화하여 찾은 노드가 블록을 생성하는 방식이다. 또한 1개의 해쉬를 복호화하여 검증받을 때 1분의 대기시간을 두어 과열된 컴퓨팅파워 경쟁을 제한한다. 지분(Stake)이 많을수록 블록을 생성할 확률은 높아지지만 이는 PoS 방식처럼 절대적이지 않다. 이 방식을 이용한다면 지분을 많이 가진 유효성 검증자(Validators)에 의한 집중화를 피하며 블록체인 네트워크에 참여하려는 진입장벽도 낮출 수 있을 것이다.
