지능사회의 등장은 급격한 패러다임 변화를 몰고올 것으로 예상된다. 역사상 처음으로 사물이 지능을 갖게 되고, 그 결과 사회의 모든 영역에서 예상치 못한 변화가 초래될 것으로 보인다. 이 글은 지능사회의 변화 방향을 전망하기 위해 우선 세계관의 변화 이슈를 분석하였다. 인간과 자연을 두 축으로 하는 이원적 세계관과 인간-기계-자연으로 이루어진 삼원적 세계관을 비교한 후 '기술이 매개하는 이원적 세계관'을 지능사회의 세계관으로 제안하였다. 이 세계관에 기초하여 지능사회의 패러다임 변화방향을 네 가지로 요약하여 전망하였다. 1. 지능의 외부화, 2. 생산성 폭발, 3. 플랫폼 사회, 4. 자기조직화 사회가 그것이다. 지능기술의 발전으로 인간은 지능증강, 생산능력 제고, 자기조직화 효과 등 다양한 이점을 누리겠지만, 다른 한편으로 기술에 대한 통제력이 약화되어 시스템 실패 가능성도 높아진다. 결론적으로 지능사회의 변화는 가치중립적이기 때문에 인간의 선택과 노력에 따라 유토피아가 될 수도 있고 디스토피아가 될 수도 있다.

현대 사회는 불특정 다수를 대상으로 자행되는 각종 사고와 범죄 위협으로 인하여 사회 전반에 걸쳐 개인의 보안 의식이 증가되며 다양한 감시 기법이 활발히 연구되고 있으나, 여전히 단순 부주의 또는 오작동으로 인한 강인성 저하가 발생하여 보다 높은 신뢰성을 갖는 감시 기법이 요구된다. 이에, 본 논문에서는 다양한 환경 및 동·정적 변화 감지에서의 낮은 강인성을 보완하고 비용 효율성 문제를 해결하기 위한 실시간 변화감지 기법을 제안한다. 변화 감지 구현을 위해 데이터 군집화 기법으로 응용되고 있는 자기 조직화 신경망을 활용하였으며, 실내 사무실 환경에서의 모의실험을 통해 기존 영상 감시 시스템에서 응용되는 감지 기법 대비 뛰어난 잡음 강인성과 이상 감지 판단의 우수성을 확인할 수 있었다.

With the rapid development of the tourism economy, large-scale construction of tourist attractions to achieve resource utilization and ensure the healthy development of the tourism industry has become a hot topic. However, there are still issues with resource utilization and coordinated management in the economic development of the tourism industry, which in turn affects the coordinated development of the tourism industry economy. Therefore, this study utilizes self-organization theory to explore the structure, organizational mechanism, conditional driving force of evolution, and evolutionary operation mechanism of the tourism system, analyze the current tourism situation in Hunan Province and related regions, and construct a self-organization evolution model of the tourism system. The result shows that the cumulative variance contribution rate of tourism areas in Hunan Province is 78.8%, with Zhangjiajie having the highest industrial management factors and tourism resource levels in the province, with 1.6 and 3.2 respectively. Hunan Province has abundant tourism resources but overall uneven development, with a comprehensive score of -1.03. Therefore, it is necessary to leverage the coordination advantages of various departments and industries to promote sustainable and healthy development of tourism areas. The self-organizing evolution of the tourism system not only discovers the current problems of the tourism industry, but also provides theoretical support and mechanism suggestions for the tourism system.

In resolving industrial quality control problems, a vector of multiple quality characteristic variables is involved rather than a single variable. However, it is not guaranteed that a multivariate control chart based on statistical methods can monitor abnormal signal in case that small changes of relationship between each variables causes abnormal production process. Hence a quality control system for real-time monitoring of the multi-dimensional quality characteristic vector under a multivariate normal process is needed to enhance tile production system quality performance. A pattern analysis approach based on self-organizing map (SOM), an unsupervised learning technique of neural network, is applied to the design of such a quality control system. In this study we present a new material quality control system based on pattern analysis approach and illustrate the effectiveness of proposed system using actual electronic company material data.

In this paper we propose a new method to determine the learning rates of fuzzy learning algorithm(FLA) in nonlinear MIMO system. The state feedback gains are used from the linearized system of the nonlinear MIMO system. Through this method, it is easy to determine the learing rates. And it is quarauteed the good convergence and confirmed the performance of FLA is better than that of linear controller(LC) through the simulation. Acrobatic robot system is selected as an example(one-input two-output system), and FLA is implemented through the experiment.

The use of the internet to facilitate commerce among companies promises vast benefits. Lots of e-marketplaces are building for several industries such as chemistry, airplane, and automobile industries. This study proposed new B2B EC business model for the shipping industry which concerns relatively massive fixed assets to be fully utilized. To be successful the proposed model gives participants to support useful information. To do this the expert system is constructed as the hybrid prediction system of neural network (NN) and memory based reasoning (MBR) with self-organizing map (SOM) and knowledge augmentaton technique using qualitative reasoning (QR). The expert system supports participants useful information coping with dynamic market environment. with this transportation companies are induced to participate in the proposed e-marketplace and helped for exchanges easily. Also participants would utilize their assets fully through B2B exchanges.

With the expansion of e-commerce, E-marketplace has become one of the most discussed topics in recent years. Limited theoretical works, however, have been done to optimize the practical use of e-marketplace systems. Other potential issues aside, this research has focused on this problem: 'the participants waste too much time, effort and cost to find out their best partner in B2B marketplace.' To solve this problem, this paper proposes a system which provides the user-company with the automated and customized brokering service. The system proposed in this paper assesses the weight on the priorities of a user-company, runs the two-stage clustering algorithm with self-organizing map and K-means clustering technique. Subsequently, the system shows the clustering result and user guide-line. This system enables B2B marketplace to have more efficiency on transaction with smaller pool of partners to be searched.

In this paper a new algorithm of learning and evolving artificial neural networks using gene expression programming (GEP) is presented. Compared with other traditional algorithms, this new algorithm has more advantages in self-learning and self-organizing, and can find optimal solutions of artificial neural networks more efficiently and elegantly. Simulation experiments show that the algorithm of evolving weights or thresholds can easily find the perfect architecture of artificial neural networks, and obviously improves previous traditional evolving methods of artificial neural networks because the GEP algorithm imitates the evolution of the natural neural system of biology according to genotype schemes of biology to crossover and mutate the genes or chromosomes to generate the next generation, and the optimal architecture of artificial neural networks with evolved weights or thresholds is finally achieved.
