This paper deals with the problem of the global stabilization for a class of ocean structure systems. It is well known that, in general, the global asymptotic stability of the ocean structure subsystems does not imply the global asymptotic stability of the composite closed-loop system. The classical fuzzy inference methods cannot work to their full potential in such circumstances because given knowledge does not cover the entire problem domain. However, requirements of fuzzy systems may change over time and therefore, the use of a static rule base may affect the effectiveness of fuzzy rule interpolation due to the absence of the most concurrent (dynamic) rules. Designing a dynamic rule base yet needs additional information. In this paper, we demonstrate this proposed methodology is a flexible and general approach, with no theoretical restriction over the employment of any particular interpolation in performing interpolation nor in the computational mechanisms to implement fitness evaluation and rule promotion.

The purpose of this study is to verify the structural path differences among the quality of self-sufficiency services and the job satisfaction and the effectiveness of self-sufficiency. To fulfill this purpose, all data for this analysis were collected from participants who belongs to the 31 local self-sufficiency centers in Seoul. The findings are as follows. First, we found that there were no statistically significant differences among the groups of the quality of self-sufficiency services and the job satisfaction and the effectiveness of self-sufficiency according to the type of self-sufficiency program. This means all the same degrees of effectiveness that participants of social employment program and market type program and self-sufficiency community was perceived. In addition, although there were no statistically significant differences among the groups of the quality of self-sufficiency services and the job satisfaction and the effectiveness of self-sufficiency according to the type of self-sufficiency program, we found that the differences among groups existed partially with theoretical model established in this study. Through the above results, the policy limitation and suggestion were presented about effectiveness of current self-sufficiency.

Through the improvement of the Labor Relations Act, the Social Insurance Act, and the Artists Welfare Act for occupational status and rights of artists, the character of workers, joining exception in the Employment Insurance Act, and applying exception in the National Health Insurance Act and the National Pensions Act should be recognized. For this, the scope of workers should be expanded through the interpretation of the court and legislation of the Labor Relations Act, and supporting range of social insurance should be expanded by applying exception in the National Health Insurance Act and joining exception in the Employment Insurance Act for artists who are currently excluded. Artists' compensation insurance that is an optional entry system and paid entirely by artists need to have effectiveness of the system through insurance support. The Artists Welfare Act also needs to be revised to strengthen legal protection for artists and it is important to secure finances for artists' welfare projects. The standard contract should be mandatory and a career certification system for artists should be established so that artists who need welfare benefits can not be omitted.

SMEs in Korea are suffering from severe manpower shortage due to poor incentive system and employees' frequent change of jobs. So far, the government has made continuous efforts to solve these problems, but SMEs still have the same problem. It is critical for SMEs to maintain core employees for long term who can directly contribute to the business performance. However, Korean manpower policies for SMEs has mainly focused on hiring new recruits and attracting experienced high caliber employees to SMEs. Relatively, policies for attracting in-house employees to work for longer term were insufficient. This paper focuses on providing strategic policy options to make core employees stay in the company for longer term. For this, it identifies the concept and features of core employees and reviews the necessity of introducing the Mutual Aid Project. Also, it suggests the way to enhance the effectiveness of policy by analyzing current Mutual Aid Fund programs in Korea.

The tactical employment is a critical factor to win the war in the modern battlefield. To apply optimized tactics, it needs analyses related to a battle system. Normally, M&S (Modeling & Simulation) has been studied to analyze data in general problems. However, this method is not suitable for military simulations because there are many variables which make complex interaction in the system. For this reason, we suggested the optimized simulation framework based on the M&S by using DPSO (Discrete binary version of PSO) algorithm. This optimized simulation framework makes the best tactical employment to reduce the searching time compared with the normal M&S used by Monte Carlo search method. This paper shows an example to find the best combination of anti-torpedo scenario in a short searching time. From the simulation example, the optimized simulation framework presents the effectiveness.

To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain.
