본 논문은 Qi 시스템 제어를 위한 지능형 디지털 재설계 접근 방안을 제안한다. 디지털 재설계란, 기존의 안정화 된 연속시간 플랜트와 이산 시간에서 설계된 디지털 제어기와의 상태 접합 및 안정도 분석을 통해 전체 시스템을 재구성 하는 것을 말한다. 퍼지 모델링을 통해 Qi 시스템을 퍼지 규칙으로 표현하며, 디지털 재설계를 통해 재설계된 디지털 제어기를 통해 이를 제어하게 된다. 주어진 조건은 LMI를 통해 표현되며, 시스템의 안정도를 증명함으로써 디지털 제어기절계의 활용성 및 가능성을 검증하고자 한다.

The purpose of this study is to suggest an anti-aging health care plan through a literature analysis of the life activity system of Oriental Medicine. The source of normal maintenace, development, and change of the natural world and the human body's life activity process is the dynamical cooperative equilibrium of the internal Shen-Ji's discipline that creates, grows, changes, makes differences and stores(生长化收藏) and external Qi-Li's process of change from birth to growth, maturity to old age and ending of life(生長壯老已). Therefore, it was analyzed that the natural and human life activity processes are normally maintained, developed, and transformed. As a result, when the natural healing power of Genuine-Qi, the source of the human vitality, rises with the 'breathing massage' that combines a static breathing method which is anti-aging health care method applying the lifting entering movement of Qi and a dynamic abdominal massage, and it harmonizes the Shen-Ji which is the life process system and Qi-Li so that it is believed to be helpful in prolonging a healthy lifespan.

In this paper, a novel DPSO-QI (Distributed PSO with quantum-infusion mechanism) algorithm improving one of the fatal defect, the so-called premature convergence, that degrades the performance of the conventional PSO algorithms is proposed. The proposed scheme has the following two distinguished features. First, a concept of neighborhood of each particle is introduced, which divides the whole swarm into several small groups with an appropriate size. Such a strategy restricts the information exchange between particles to be done only in each small group. It thus results in the improvement of particles' diversity and further minimization of a probability of occurring the premature convergence phenomena. Second, a quantum-infusion (QI) mechanism based on the quantum mechanics is introduced to generate a meaningful offspring in each small group. This offspring in our PSO mechanism improves the ability to explore a wider area precisely compared to the conventional one, so that the degree of precision of the algorithm is improved. Finally, some numerical results are compared with those of the conventional researches, which clearly demonstrates the effectiveness and reliability of the proposed DPSO-QI algorithm.

문제: 투약오류는 의료기관 전반에서 가장 많이 발생하는 오류의 하나이며, 환자에게 중대한 위해를 초래하기도 한다. 특히 고농축전해질은 문제발생의 가능성과 위험성이 높아 지속적인 관리 및 교육을 필요로 하고 있다. 목적: 발생한 투약오류 건에 대한 근본원인분석을 시행함으로써 유사사례가 발생하는 것을 예방하여 환자안전을 도모하고자 한다. 의료기관: 연세대학교 세브란스병원 질 향상 활동: 투약오류 건에 대해 근본원인분석 시행 후 고위험약물 관련 내규를 보완하였고, 고위험약물에 대한 Alert System 개발, 고위험약물 라벨 부착, 약 처방 관련 의료진 교육을 시행하였다. 개선효과: 고위험약물 투여와 관련된 시스템 개선 활동 이후 유사사례는 발생하지 않았고, 의료진 교육을 통하여 환자안전에 대한 인식과 중요성을 더욱 증가시켰다.

Objectives We carried out this study to know that there is any differences on the health condition of the middle aged women between Sasang coustitution. We used Diagnosis System of Oriental Medicine(DSOM) for diagnosis and determining pattern identification. Methods This research was approved by the Dongeui University Oriental Hospital Institutional Review Board (certificate no. 2011-06). From March 2012 to October 2012, we examined Kupperman's index, the MENQOL, DSOM, and Sasang Constitution of 291 women from the general population, with ages ranging from 40 to 60 years. And we compared the results statistically by the chi-square test and F-test. Results and Conclusions We excluded 4 Taeyangin to analyze because they were few, and analyzed 287 subjects which were 53 Soyangin, 131 Taeeumin, and 103 Soeumin. 1. The pathogenic factors that showed significant differences were deficiency of qi, insufficiency of Yin, heat on the frequency of the output and deficiency of qi, heat, phlegm on the mean of pathogenic factor score. Deficiency of qi was higher in Soeumin, insufficiency of Yin and heat were higher in Taeeumin, and phlegm was higher in Taeeumin and Soeumin. Overall, Soyangin tended to be lower than others on both the frequency of the output and the mean of pathogenic factor score. 2. The middle aged women with ages ranging from 40 to 60 years tended to be dryness, kidney, damp and became to be blood-deficiency, stagnation of qi, heart easily. Soyangin was more health than others, Taeeumin tended to be heat, phlegm, insufficiency of Yang, and Soeumin tended to be deficiency of qi.

In this study, the influences of rail surface roughness on dynamic wheel-rail forces currently employed in conventional lines were assessed by performing field measurements according to grinding of rail surface roughness. The influence of the grinding effect was evaluated using a previous empirical prediction model for dynamic wheel-rail forces; model includes first-order derivatives of QI (Quality Index) and vehicle velocity. The theoretical dynamic wheel-rail force determined using the previous prediction equation was analyzed using the QI, which decreased due to rail grinding as determined through field measurements. At a constant track support stiffness, an increase in the QI caused an increase in dynamic wheel-rail forces. Further, it can be inferred that the results of dynamic wheel-rail analysis obtained using the measured data, such as the variation of QI due to rail grinding, can be used to predict the peak dynamic forces. Therefore, it is obvious that the optimum amount of rail grinding can be determined by considering the QI, that was regarding an operation characteristics of the target track (vehicle velocity and wheel load).
