In order to control waves in coastal zones effectively, multi-cylinder piles as the economical structures are suggested. A three dimensional hydraulic model experiment was performed to investigate the hydraulic characteristics of the structure. An experimental study was carried out research the effect of wave control and harbor tranquility through the wave height analysis for the existing concrete wave breaker and the structure with acrylic multi-cylinder piles type at the same location. In the results, the effective order of harbor tranquility is shown as the wave breaker > the staggered arrangement of multi-cylinder piles > the regular arrangement of multi-cylinder piles.

Environmental and safety problems are one of the most important factors in designing coastal wave control structures and maintaining facilities in coastal zone. This study suggests the multi-cylinder piles as a profitable structure for preserving coastal zone as well as controlling the wave effectively. The hydraulic model experiment was performed to investigate the effect of erosion control of the structure. The experimental study was carried out to research the effect of erosion control in the coastal zone for existing a concrete wave breaker and the structure with multi-cylinder piles placing at the same location. As a result multi-cylinder piles reduced erosion at each sides of structure and occured sedimetation at front of structure.

The purpose of this research is both to analyse the dynamics of welfare pluralism in the personal social service policy for elderly British people and to provide policy implications based on analysis of the post World War II time era up until the end of the New Labour Government. Content analysis of government and parliament reports, minutes, scripts for party conferences, legislations, declassified government documents, and institutes' reports of the Conservative, Labour, and New Labour Governments from 1945 to 2010 shows that the governments played only assistive roles in welfare pluralism at any given point in time. The negative experiences of elderly British can be attributed to the unbalanced structure of roles held by public and private institutions for personal social services. They ultimately have important policy implications for the foundation of welfare pluralism in elderly Korean community care by the Moon Jae-in government.

This study has started from the political process of local community power structure to elaborate the reason why both a majority of cultural artists and cultural artist organizations want to be against establishing the local Foundation for Arts and Culture. The cultural artists and cultural artist organizations believe that the establishment of the local Foundation for Arts and Culture might threaten not only their monopolistic status or their livelihood in the local market relying on public supports, but also make them being marginalized from the potential supports. Therefore many of them have somewhat unfavourable opinions about its establishment. Drawing from the Jellabuk-do case, their concern of being isolated from the monopoly by the local Foundation for Arts and Culture are reduced to publicized discourses such as powerization, the lack of expertise, the loss of independence, and the fall of business. When constructing the Foundation for Arts and Culture, the major values are 'Pluralism' and 'Fairness'. On one hand, the terms of Fairness means that it should be fair in operations, support and executive composition. On the other hand, Pluralism means that policy-making rights should be distributed to various groups, not owned by some specific groups. Some plans for building Foundation for Arts and Culture are needed to make diverse classes and groups to expect the pluralistic interests emerged eventually.

A new Monte Carlo (MC) simulator for electron beam lithography process in the multi-layer resists and compound semiconductor substrates has been developed in order to fabricate and develop the high-speed PHEMT devices for millimeter-wave frequencies. For the accurate and efficient calculation of the transferred and deposited energy distribution to the multi-component and multi-layer targets by electron beams, we newly modeled for the multi-layer resists and heterogeneous multi-layer substrates. By this model, the T-shaped gate fabrication process by electron beam lithography in the PHEMT device has been simulated and analyzed. The simulation results are shown along with the SEM observations in the T-gate formation process, which verifies the new model in this paper.

The purpose of this article is to explore French 'minima sociaux', focusing its scheme, benefit determination rule and its level appreciation. First, on the its structure domain, French 'minima sociaux' presents the plural system in which there is eight categorical benefits and one general benefit. Il is the representation of the intention to guarantee minimum income for the dead zone people out of the social insurance application and also a historical product in different period, by different logic of benefits implementation. Second, comparing nine benefits based on the benefit determination rule, level of benefits for the poor without work ability is higher than one for the poor with work ability. Il represents one polarized perception toward for the poor according to have or not its work ability. Third, comparing level of 'minima sociaux' with relative poverty line, the level of the most 'minima sociaux' is placed under the poverty line. Nevertheless, it must not forget that 'minima sociaux' plays its role as the fundamental alternative for poverty alleviation, but not the only alternative. Fourth and finally, comparing with minimum income guarantee(SMIC in french), level of RMI benefit is estimated merely on the 50% of SMIC. We can consider that it is the result of the interaction of the complex factors, as the limited role of the state toward the minimum income guarantee for the RMI beneficiary and the intervention the logic of status instead of the logic of need, etc..

Traditionally, the paddy fields in Korea, besides rice production, have multifunction such as water supplement source to ground water and prevention of floods via securing the rainfall during a monsoon season. Therefore, the development of food production technology to be adapted in the future climate change in Korea has to take into account the integration of the multi-function of paddy fields with IT, BT, and NT. This demands forward movements in agriculture paradigm as followings. First of all, a national strategy is necessary to maintain and conserve the agricultural farmlands. Second the agricultural structure needs to shift to low carbon green agriculture taking into account the energy balance. Third our attitude needs to be changed toward maximizing the multifunction of the paddy farming.

We construct a universal derivation module of an R-algebra which is constructed by means of a tensor product of three copies of the algebras.
