The purpose of this investigation is to evaluate the effects of the Nuegra on enhancement of the masculine and physical activities in general through measuring changes of the testosterone, FSH and subjective symptoms like fatigue, insomnia, urinary stream, muscular weakness, libido and erectile dysfunction. Total 168 male subjects were enrolled from 12 urology, internal medicine clinics and general practitioner, During the 6-week investigational period, 2 capsules of Nuegra were given to the subjects right after meal for 4 weeks, and 1 capsule of Nuegra was added each time in subjects with no or minimal effect. Testoster-one and FSH levels were measured at first visit and last visit, for evaluating masculine activities. To avoid bias and standardize the test results, only one clinic was assigned as a central lab, and all blood samples were transferred. General information and subjective symptoms were evaluated at first visit and at 2 weeks interval, week 2, 4 and 6 using VAS (Visual Analogue Scale). The mean age of the subjects were 51.8${\pm}$8.2 years old (range: 36.1-82.1). Based on the subjects who were tested on testosterone and FSH levels at day l and week 6, the means were 4.4${\pm}$1.4 nmol/L (range: 2.6-7.7), 8.6${\pm}$9.6 mIU/mL (range: 0.3-40.4), respectively at day 1. At week 6, the results were 4.9 ${\pm}$1.6 (2.6-8.9 range), 9.4${\pm}$13.1 (1.0-53.9 range), respectively. Marginally significant difference between pre-dose and post-dose was present. Statistically significant differences were revealed in general assessment for subjective symptoms, fatigue, insomnia, erectile dysfunction, etc. In fatigue, response rates were 39.6, 65.4 and 76.4% at week 2, 4 and 6, respectively (P < 0.0001). Response vates for erectile dysfunction were 13.4, 41.2 and 72.7% at week 2, 4, and 6 (P < 0.0001), respectively, Response rates for libido were 13.6, 51.6 and 73.5% at week 2, 4, and 6 (P < 0.0001), respectively. For urinary stream response rates were 26.9, 44.7 and 66.8% at week 2, 4, and 6 (P < 0.0001), respectively. VAS for muscular weakness did not show significant results that response rates were 40, 60 and 80% at week 2, 4, and 6 from 8.2 (P ＝ 0.24), respectively. Response rates for insomnia were 50, 60, 100% at week 2, 4, and 6 (P < 0.0001), respectively. The results shows that Nuegra tends to enhance masculine activities including libido, erectile dysfunction and urinary stream and also effective for improving general conditions especially insomnia, muscular weakness and fatigue. In conclusion, this investigation has demonstrated that Nuegra does not only have tendency to increase masculine activities through increased secretion of the testosterone and FSH but also improve general conditions such as erectile dysfunction, libido, fatigue and muscular power.

본 논문에서는 맥진기로 취득한 맥진 파형을 참고로 하여, 인체에 분포된 12경맥의 좌우 대표측정점의 임피던스를 24채널의 양도락 진단기를 이용해 측정하였다. 그리고, 퍼지 논리에 따라 각 경락의 허실을 진단한 후, 경락의 유주방향(流注方向)에 순(보)하거나 반(사)하는 자기 자극을 가하여 맥파와 경락의 허실정도가 어떻게 변화하는가를 연구하였으며, 궁극적으로는 진단과 동시에 자기 자극을 가하여 음양과 오행의 균형을 이루게 하는 자기치료 시스템에 관해 연구하였다. 자기 자극에서는 좌우 각 12경맥의 수족 대표측정점의 일정 부위에 방향과 시간을 가변할 수 있는 자기 자극기를 개발하여 이용하였다. 치료방법은 양도락 진단을 통하여 허와 실을 구분하고 난 뒤, 심하게 허한 양의 경락은 하향자극 조정을, 심하게 실한 양의 경락은 상향자극 조정을, 심하게 허한 음의 경락은 상향자극 조정을, 심하게 실한 음의 경락은 하향자극 조정을 할 수 있도록 PC에서 제어하도록 하였다.

k-nearest neighbor (K-NN) is a well-known classification algorithm, being feature space-based on nearest-neighbor training examples in machine learning. However, K-NN, as we know, is a lazy learning method. Therefore, if a K-NN-based system very much depends on a huge amount of history data to achieve an accurate prediction result for a particular task, it gradually faces a processing-time performance-degradation problem. We have noticed that many researchers usually contemplate only classification accuracy. But estimation speed also plays an essential role in real-time prediction systems. To compensate for this weakness, this paper proposes correlation coefficient-based clustering (CCC) aimed at upgrading the performance of K-NN by leveraging processing-time speed and plurality rule-based density (PRD) to improve estimation accuracy. For experiments, we used real datasets (on breast cancer, breast tissue, heart, and the iris) from the University of California, Irvine (UCI) machine learning repository. Moreover, real traffic data collected from Ojana Junction, Route 58, Okinawa, Japan, was also utilized to lay bare the efficiency of this method. By using these datasets, we proved better processing-time performance with the new approach by comparing it with classical K-NN. Besides, via experiments on real-world datasets, we compared the prediction accuracy of our approach with density peaks clustering based on K-NN and principal component analysis (DPC-KNN-PCA).

홍수 시뮬레이션에서 중요한 요소는 강우량, 강우강도 등의 수리 수문자료와 3차원 지형모델, 수리학적 홍수 계산 모형으로 이 중 어느 한 정보의 정확도 및 신뢰성이 낮게 되면 홍수범람 예측 정보의 정확도 및 신뢰성의 확보가 어렵게 된다. 이에 본 연구는 기존 수치지도 및 현황도로 제작한 지형모델과 항공 LiDAR 데이터로 제작된 3차원 지형모델에 대하여 기존의 설계빈도별 홍수위에 따른 침수취약지역을 비교하여 3차원 지형모델의 정확도 차이로 인한 문제점을 분석하여 홍수 시뮬레이션에 대한 LiDAR데이터의 활용성을 제시하고자 하였다.

In a traditional hierarchical inventory system, direct orders are the only information for inventory management that is exchanged between the firms involved. But due to the rapid development of modern information technology, it becomes possible for the firms to share more information in real time, e.g. demand and inventory status data. And so the term Supply Chain has emerged because it is seen as an important source of competitive advantage. Now it is possible to challenge traditional approaches to inventory management. In the past, one of the de-facto assumptions for inventory management was that the demand pattern follows a specific distribution function. However, it is undesirable to apply this assumption in real situations because the demand information in the supply chain tends to be distorted due to the bullwhip effect in a supply chain. To overcome this weakness, we propose a new solution method using NN (Neural Network). Our method proceeds in three steps. First, we find the patterns of optimal reorder points by analyzing past data. Second. train the NN using these pattern data and finally decide the reorder point. Using simulation experiment, we show that the proposed solution method gives better result than that of traditional research.

웹 프로토콜인 HTTP은 이전 상태 정보를 저장하지 못하는 stateless 특성을 해결하기 위해서 쿠키(cookie)가 제안되었다. 그러나 쿠키는 평문 형태로 전송이 되며, 사용자 컴퓨터에 일반 텍스트 형태로 저장된다. 따라서, 공격자에게 쉽게 노출되어 쿠키 파일의 복사, 수정이 가능하여 보안적인 안전성에 심각한 위험이 존재한다. 본 논문에서는 이러한 쿠키의 보안 문제를 해결하기 위해서 공개키 인증서 기반의 새로운 보안 쿠키를 설계한 후 이를 구현하였다. 제안된 보안 쿠키는 사용자와 웹 서버간의 상호 인증 및 사용자 정보의 기밀성 및 무결성을 제공한다. 또한 웹 서버의 사용자 관리에 따른 부가적인 관리비용을 최소화시키기 위해 사용자 관리 정보를 보안 쿠키에 포함시킬 수 있다. 부가적으로 제안 방안의 성능 평가를 위해 기존의 HTTP 환경에서의 보안을 위해서 널리 사용되고 있는 SSL과의 수행 시간을 비교 분석하였다.

It is the approach of embedded system design that analyzes COS(Cut Out Switch) failure in the power distribution and an instantaneous breakdown of power distribution supply could cause the weakness of industrial competence and therefore we need to feed the stable power distribution with developing the technology of open-source embedded system. In this paper, we apply the LoRa technology which is the Internet of Things(IoT) protocol for low data rate, low power, low cost and long range sensor applications. We designed the hardware and software architecture setup and experimented the embedded system with network architecture and COS monitoring system including accelerometer for detecting the failure of distribution line and sensing the failure of its fuse holder by recognizing the variation and collision and afterwards sending the information to a gateway. With experimenting we designed the embedded platform for sensing the variation and collision according to the COS failure, monitoring its fuse holder status and transferring the information of states with LoRa technology.
