Conditinal weakly convergence of the blockwise bootstrapped empirical process for stationary sequences to the appropriate Gaussian process is reestablished particularly for severely dependent $\alpha$-mixing sequences. Issue of block size is discussed from the point of validity of bootstrap method.

In this paper the issue of convergence rate is introduced for a learning control scheme we have developed and applied for tracking of unknown linear systems. A sufficient condition under which the output trajectory converges exponentially fast is obtained using the controllability grammian of controllable linear systems. Under the same condition it is also shown that the learning control input converges exponentially with the same rate as the rate of output convergence. A numerical example with computer simulation results is presented to show the feasibility of the scheme.

The present study attempted to explore effective scanning and monitoring in process of risk management on agri-marine products distribution policy. The interest public's group interests clash in accordance with theme for issue on marking policy. For executing a better systematic scanning and monitoring on actual affairs of marketing, selecting information personnel, gathering and analysing information, issue and risk management and their valuation with ongoing and simultaneously. Especially, In order to explore effective scanning and monitoring as a model of risk management, the study attempted to analyze within and without environment of marketing, to analyze issue management strategy, to evaluate issue activity for likelihood and impact, risk cycle analysis, interest public's group concerned, grade of interest public's group threatened(power, legitimacy, willingness), rapport(staying close, credibility, meeting expectation). And the study make an ongoing observation progress of subjects, and the serious subjects need have made an close observation. The study suggested to establish friendly relationship between organization and interest public's group, and to regularly accomplish two-way symmetric communication.

Many first aiders suffer from the stress of working in uncertain disaster sites. The stress of responding to disasters leads to an increase in post-traumatic stress disorder (PTSD) and a decrease in psychological well-being. It also has many negative effects on the meaning in life for first aiders. Reduced meaning in life will result in many societal opportunity costs due to decreased health and work engagement. To address this issue, this study conducted a survey to analyze the level of meaning in life of first aiders. The results indicated that the overall level of meaning in life of first aiders is very low. This issue needs to be addressed sooner rather than later, given the increasing trend of emergency response. Based on the results of the study, measures were proposed to reduce PTSD and psychological stability by restoring the meaningfulness of first aiders' lives.

As smart convergence occurs, solving the digital divide issue for weak layers such as the elderly, handicapped and poor groups is becoming an emerging issue. This study aims to promote information service to encourage active participation of the weak layers and to bridge the digital divide among those under the digital switchover and the smart phone convergence environments. This study, comparing the environments of Korea and other major countries with respect to digital divide, found some differences and tried to suggest proper policies for Korea to remain as a leading IT country. We expect this study to help the government, industries, schools cope with the divide issues and establish proper policies to provide weak layers with equal opportunities to IT in the coming smart convergence era.

Analyzing the diffusion of a convergence product is a new and challenging research field. It is very difficult to find research dealing with this issue due to the inherent complexity and lack of data. In analyzing the diffusion of a convergence product, we should simultaneously take into account its relationship with related single-function products because of their similarities in terms of technology and functionality. In this study, we empirically analyze the diffusion of the convergence mobile phones in South Korea and find that the convergence products can affect the diffusion of MP3 players and digital cameras positively or negatively. This research may be significant for business strategies in technology management and product development.

This paper, so far to analyze the research trends in the issue that has been discussed for the introduction of private investigation institutions, by projecting its suggestion, want the investigation purpose of presenting the desirable introduction direction. The analyzed issue was extracted for existing research material on the introduction of private investigation institutions. Investigators pointed out issue is the name, business scope, corporate, qualification system (eligibility criteria and test), education, association establishment, regulatory agencies, has been included in the eight categories such as legislation form. For the name, I think there is a need to unify under the name "detective". For the scope of work, the amendment is difficult law, place an overview of the general business rules, more specific and detailed investigation business content, to discipline through the ordinance it is possible to be rational. Private investigation institutions, I think the need for limited operations of the corporation. For education, the new education and re-education on a regular basis I do for the private investigation workers. You must be one of the National Police Agency to the management authority. Legislative form, not to be defined by its own law, the revision of the security law, but that is to complement the provisions for private sector research system is effective.

Existing link-based Frank-Wolfe algorithm has been widely used, thanks to its ease of simulation and stable results; however, it comes with low convergence issue towards near the optimum value. Such issue was not considered as a major drawback in the past. However, in the present, some arguments have occurred over the method's stability, analysis time, and other limits as the size and details of the fundamental data for traffic analysis have vastly improved. Therefore, this paper compared the theoretical attributes and the pros and cons between the Frank-Wolfe algorithm and the Origin-based algorithm and Path-based algorithm newly being developed. As a result of this paper, there is possibility that a problem of stability may arise depending on the convergence and exit criteria. Thus, In practice, this effort to derive the appropriate level of convergence is required to secure and stable results.
