The study explored the work-life balance of three dual-earning couples using the household economics approach according to the hermeneutics paradigm. Three families were analysed. The couples were interviewed individually with a non-structural interview guide about their work history and life history, and with a semi-structured interview and structured questionnaire about their work hours, childcare practice, husband-wife relation, household income and expenditure, and daily and weekly schedule. The results revealed the different paths and various strategies to adjust work-life balance among the cases. Strategies were discussed to facilitate changes in labor market policy, childcare policy, working place culture and family's daily life planning.

With the draining of land resources, and rising new economic and resources expansionism, finding a new and yet to be developed ${\ulcorner}treasure{\lrcorner}$ is often a fierce and competitive challenge among many nations. This is especially true for Korea confronted with its urgent needs to find new resources and strategy to maintain the current pace of societal demand and economic development in this often impatient and rapidly progressing world. The ocean world in the South Pacific provides potentials to quench both orders with promises of new ${\ulcorner}treasure{\lrcorner}$ of living and ecosystem resources such as new fisheries and new bioactive products as well as providing alternative aesthetic, recreational resources and critical informations on various societal problems such as extreme weather conditions and early wining of the consequences resulting from global environmental changes.

The purpose of this study is to identify the driven factors affecting the changes in energy-related $CO_2$ emissions in Hebei Province of China from 1995 to 2013. This study confirmed that energy-related $CO_2$ emissions are correlated with the population, urbanization level, economic development degree, industry structure, foreign trade degree, technology level and energy proportion through an improved STIRPAT model. A reasonable and more reliable outcome of STIRPAT model can be obtained with the introducing of the Ridge Regression, which shows that population is the most important factor for $CO_2$ emissions in Hebei with the coefficient 2.4528. Rely on these discussions about affect abilities of each driven factors, we conclude several proposals to arrive targets for reductions in Hebei's energy-related $CO_2$ emissions. The method improved and relative policy advance improved pointing at empirical results also can be applied by other province to make study about driven factors of the growth of carbon emissions.

Korea has relied on top down development method, in which companies, research and education institutions move into the industrial complexes established by the government. However, to improve local competitiveness, the paradigm is shifting from the government initiated industrial complex to the clusters based on the cooperative network of the region. Representative case is 'Samcheok-si Fire & Emergency industry cluster construction project' that begun in 2007. AHP technique analysis results on first-stage showed that priority was on policy and network elements, and the results of second-stage analysis show that priority was on Policy incentives to internationalize the cluster and strengthen link,. Cluster branding, Sharing of organizational culture to cope with changes in environment, Creation of group learning culture. The subject of this research is limited to Samcheok-si's the Fire and Emergency Industry cluster formation project. Therefore, the research area and standard should be expanded to increase generality in further researches.

Recently, in FMS composing of various automatic equipments, the machines with lower operating costs, and with higher operating costs and replacement costs resulting from deterioration have been appearing successively as a result of rapidly advances in technology. "Control Limit Policy" [1] by using Markov decision policy, a kind of optimal economic replacement decision, well reflects and represents this environment. In this paper, it is reviewed that the decision method of the forecasted replacement alternatives in planning horizon under technological advances is derived. The proposed method is applied to a numerical example and some characteristics are examined by sensitivity. It is clarified that the method is relatively insensitive to changes of parameters at the present decision. decision.

National information policies have to be flexible： to anticipate changes and turn them to good advantage, to scrap old approaches as they cease to be relevant and to experiment with new approaches as they cross the horizon. This flexibility implies‘a liveliness of mind’and‘a spirit of enterprise’at the policy-making level, two qualities that do not abound and which must be in demand for other national policies.

This thesis aims at presenting the improvements of terror-responsive policy that Korea has to take on the basis of terror threat to Germany and responsive policies. so, First, Korea has to prepare the ways to legislate on terror responsive policies. Second, Korea has to construct a management center to response to terror comprehensively. In addition, Korea, like Germany, has to establish cooperation center related to terror on internet to surveil and analyze information and situation.

The environmental problem come because the demage cost of environmental pollution is not properly reflected in market price. The government regulations for market is justified to solve the problem. The policy needs a close analysis of environmental, economical effect for the point of time, methods, rational decision making of the government regulations. Especially, we need to assume and analyze about social expenses by environmental pollution and policy execution. The cost-benefit analysis about environmental pollution is used to support decision making. The value of benefit about damage by environmental pollution or about improvement changes a monetary unit through the cost-benefit analysis. The working like this is said environmental material valuation or measuring valuation. This work is studied about looking for proper analysis model to apply our environmental materials.

The works of defence reliability have begun since the ILS team was organized in ROKA on March 2003. After that DAPA was opened at January 1st 2006 and those of defence reliability were reinforced. But the present of defence reliability is not enough. Many development and changes are required in the following area. The first is Master-plan making of defence reliability, and the second is making of the process of reliability. And then we have to enhance reliability of weapon system in the operation and support phase. The last is that policy is firmly executed among the defence organizations.

Purpose: This paper proposes the non-periodic preventive maintenance policy based on the level of cumulative hazard intensity. We aim to construct a cost-effectiveness on the proposed model with relaxing the constraint on reliability. Methods: We use the level of cumulative hazard intensity as a condition variable, instead of reliability. Such a level of cumulative hazard intensity can derive the reliability which decreases as the frequency of preventive maintenance action increases. We also model the imperfect preventive maintenance action using the proportional age setback model. Conclusion: We provide a numerical example to illustrate the proposed model. We also analyze how the parameters of our model affect the optimal preventive maintenance policy. The results show that as long as high reliability is guaranteed, the inefficient preventive maintenance action is performed reducing the system operation time. Moreover, the optimal value of the proposed model is sensitive to changes in preventive maintenance cost and replacement cost.
