본 논문에서는 스칼라 인수 a1, a2, a3를 매개변수화하여 갱신항을 첨가한 비선형 적응 알고리즘의 특성을 해석하고 그 구조를 나타낸다. 수렴 특성의 해석에서 평균 필터계수 벡터에 대하여 전이행열의 값이 기술된다. 그 알고리즘이 안정하기 위한 범위도 증명된다. 또한 본 알고리즘의 시정수도 유도되고, Sign 알고리즘, 기존의 LMS 알고리즘, LFG 알고리즘, QFG 알고리즘의 계산량도 비교해 본다. 평균자승의 수렴특성을 해석하고 평균자승 순환식과 초과 평균자승 오차(excess mean square error) 표현식을 유도하고 본 알고리즘이 안정하기 위한 조선도 정한다. 컴퓨터 모의실험(simulation)에서 CFG 알고리즘이 LMS, LFG 및 QFG 알고리즘보다 계산량이 증가하는 반면 수렴속도에서 현저한 향상을 보여준다.

It is increasingly apparent that nature evolved peroxiredoxins not only as $H_2O_2$ scavengers but also as highly sensitive $H_2O_2$ sensors and signal transducers. Here we ask whether the $H_2O_2$ sensing role of Prx can be exploited to develop probes that allow to monitor intracellular $H_2O_2$ levels with unprecedented sensitivity. Indeed, simple gel shift assays visualizing the oxidation of endogenous 2-Cys peroxiredoxins have already been used to detect subtle changes in intracellular $H_2O_2$ concentration. The challenge however is to create a genetically encoded probe that offers real-time measurements of $H_2O_2$ levels in intact cells via the Prx oxidation state. We discuss potential design strategies for Prx-based probes based on either the redoxsensitive fluorophore roGFP or the conformation-sensitive fluorophore cpYFP. Furthermore, we outline the structural and chemical complexities which need to be addressed when using Prx as a sensing moiety for $H_2O_2$ probes. We suggest experimental strategies to investigate the influence of these complexities on probe behavior. In doing so, we hope to stimulate the development of Prx-based probes which may spearhead the further study of cellular $H_2O_2$ homeostasis and Prx signaling.

Naval ship design and related other activities can be characterized by the complexity of the interactions among products, activities, and disciplines. Such complexities often result in inferior designs, cost overrun, and late-delivery. Hence there exist tremendous interests in both improving the design process itself and optimizing the interactions among design activities. This paper looks at the complexity of designing naval ships thereby leading to the innovation of current ship design practices using design structure matrix. It can be used to induce the optimal ordering of design activities as well as identify sources of complexities. The method presented here identifies coupled design activities useful for reducing the complexity of naval ship design as well as optimally reordering design activities. This paper recommends the use of design structure matrix method suitable for numerically optimizing the concept design process of naval ship, and reducing cost and time required in designing naval ships by modeling and analyzing the design activities and engineering tasks, defined in systems engineering planning documents.

The emergence of the metaverse, a complex three-dimensional virtual environment, has led to significant changes in the intellectual property (IP) landscape. This paper examines the challenges and legal intricacies of IP within the virtual realm, focusing on the unprecedented nature of these disputes and on the inadequacies of traditional jurisdiction methods. Drawing from international frameworks, including the International Law Association's Guidelines and WIPO's guides, the study critically explores arbitration as an alternate approach to metaverse IP disputes, analyzing its complexities and applicability. The paper further delves into challenges arising from diverse protection laws that pertain to the global nature of the metaverse, including the nuances of various digital assets like NFTs. By assessing jurisdictional difficulties, the paper addresses the adoption of decentralized justice platforms, and examines the role of Alternative Dispute Resolution (ADR) methods, this paper presents a comprehensive view of the evolving virtual legal field. It suggests that while innovative methods are emerging, traditional arbitration will likely remain the preferred choice for complex disputes, offering a balance of speed, cost-effectiveness, and legal robustness within the virtual world.

최근 한국사회복지실천에 등장한 복잡하고 혼돈스러운 현상들이 기존의 이론이나 관점으로 설명되지 못하면서 사회복지실천의 정체성과 본질에 관한 의문과 더불어 사회복지실천이 시대적 변화에 적절히 조응하고 있는지에 대한 반성이 제기되고 있다. 본 연구는 이러한 의문과 반성을 체계적으로 수행할 수 있는 이론적 틀로서 Bauman의 유동적 근대성 이론을 제시하고 이를 통해 한국사회복지실천의 현재 위상을 심층적으로 분석해 보았다. 그 결과 한국사회복지실천에서도 급속한 변화와 시대적 복합성으로 인한 혼란, 빈곤에 대한 비중 감소와 소비논리의 팽배, 영역의 세분화와 문제해결의 개인화, 관료제와 관리주의의 강화에 따른 실천성의 약화, 사회복지 정체성과 윤리성에 대한 요청 등 유동적 근대사회 특유의 현상들이 분명히 진행되고 있음을 확인할 수 있었다. 그러나 그 대응은 유동적 사회에 부합하는 수단이 아니라 기존의 고체 근대 시대의 전략과 수단을 더욱 강화하려는 방향으로 전개되고 있기 때문에 한국사회복지실천이 당면하고 있는 유동화의 위기를 돌파하기 위해서는 시대적 요구를 반영한 사회복지실천의 정체성 확립과 전문가의 자율성 확보가 전제되어야 함을 제언하였다.

This paper considers the shortest path problem combined with Min-Min-Sum objective for solving the problem of the military logistics. This paper develops a polynomial-time algorithm for the optimal solution. To analyze the real combat situation, the ability time and distance time of communication line are considered. The complexities of algorithm between previous study and the algorithm developed in this paper is presented. Finally we provide a simple example of application with randomly generated problem.

The behavior of woman consumer is changing according is its situation and includes its complexity. The complexities are being changed by the economic, psycalogical social, and cultural factors. The influence of group on the behavior of consumer -the primary, secondary, formal, informal, membership and reference group -has a great influence on the buying decision. Though manufacturers have pursued only behavior, now they must pursue the positive promotion behavior on the basis of convert behavior of current consumer's behavior. The research of consumer's behavior must be performed scicntificallyan and it must be more practical approach.

This paper provides equation for computing the AOQ of an unreliable random FMS. The FMS is described using open central server model with network GI/G/S Queues. And the equation for AOQ is simplified due to computational complexities. Numerical example is used to show the effect of AOQ according to inspection location, reliability of equipment in an FMS, and the effect of difference of routing probability is compared after finding the AOQL of each machine center.

Many fractal objects observed in reality are characterized by some irregularities or complexities in their features. These properties can be measured and analyzed by means of fractal dimension. However, in many cases, the calculation of this value may not be so easy to utilize in applications. In this respect, we have treated a formal method to estimate the dimension of fractal curves.
