Now it is not useful the theory about civil-military relationship that have been analysed for power games between military and civilians Korean society is going on governance society managed by cooperating network of government, civilian society and business market These social change require for new context about civil-Military relationship. Military leadership must contribute desirable civil-military relationship This study will suggest the direction about military leadership for desirable civil-military relationship. Now political issues about military intervention to the government are almost settled, but the worry about complications between military and civilians exist in the part of low issues like policy-making. Another important issues is military leadership about the style of social-being. In recent years, social change is very complex and speedy like global networking and diversity, leadership environment also, changed like leadership paradigm shift. Military leadership must be examined from the principle to the context of social integration At the present age, individual soldier is citizen in uniformed. Also military leadership must to seek the principle in the citizen mind like citizenship. Another charactristics of present day military is influence of high technogy. For the high-tech war military need the transition about science and technology from the whole society. In the context of above the development of military leadership are suggested as follows. First, the development of military control leadership must besought to the context of cooperation between government and military. Government must provide the system to strengthen military professionals in the process of policy-making about national security Second, military leadership must embody the important social values through the advanced military making, Third, military leadership must provide the adaptability to the society through the military education of their soldiers Forth, military leadership must be contributed to the social integration and to the growing up individual soldiers like their socialization and their achievement. Five, an important subject of military leadership is the creation of desirable military culture through the harmony of social culture and military culture.

Over the North East Asia, extreme anomalous precipitation were observed in 2013 and 2014. During 2013 summer the precipitation was found to be higher (two standard deviation) than the climatological mean of the region; whereas during 2014, which was a borderline El Ni?o year, precipitation was found to be lower (one standard deviation). To understand the differences of these two anomalous years the Global/Regional Integrated Model system (GRIMs) has been used. The study found that low landsurface temperature and high sea-surface temperature over ocean caused a smaller land-sea contrast of surface temperature between East Asia and North West Pacific Ocean in 2014, which could have caused an eastward shift of mean monsoon circulation in that year compared to the circulation in 2013. Due to a change in the lower level circulation and wind field over East Asia the evaporation and moisture transport patterns became very different in those two years. In 2013, this study found high latent heat flux over Eastern China, which implies an increased surface evaporation over that region, and the moisture transported to the north by the mean monsoon circulation; whereas, there was no correlated transport of moisture to the North East Asia during 2014. The precipitable water over North East Asia has a stronger correlation with the latent heat flux over southern land region than that from Ocean region in the eastern side in both the years. A new approach is proposed to estimate the sub-grid scale hydrometeors from GRIMs, overestimated in the existing model.

This study examines the temporal evolution of the extratropically forced tropical response in an idealized aquaplanet model under equinox condition. We apply a surface thermal forcing in the northern extratropics that oscillates periodically in time. It is shown that tropical precipitation is unaltered by sufficiently high-frequency extratropical forcing. This sensitivity to the extratropical forcing periodicity arises from the critical time required for sea surface temperature (SST) adjustment. Low-frequency extratropical forcing grants sufficient time for atmospheric transient eddies to diffuse moist static energy to perturb the midlatitude SSTs outside the forcing region, as demonstrated by a one-dimensional energy balance model with a fixed diffusivity. As the transient eddies weaken in the subtropics, a further equatorward advection is accomplished by the Hadley circulation. The essential role of Hadley cell advection in connecting the subtropical signal to the equatorial region is supported by an idealized thermodynamical-advective model. Associated with the SST changes in the tropics is a meridional shift of the intertropical convergence zone. Since the time needed for SST adjustment increases with increasing mixed layer depth, the critical forcing period at which the extratropical forcing can affect the tropics scales linearly with the mixed layer depth. Our results highlight the important role of decadal-and-longer extratropical climate variability in shaping the tropical climate system. We also raise the possibility that the transient behavior of a tropical response forced by extratropical variability may be strongly dependent on cloud radiative effects.

Two-stage continuous culture system has been studied intensively to maximize the productivity of a cloned gene product in unstable recombinant microorganism. As an effort to optimize the two-stage process, transient behavior of the second-stage was studied theoretically as well as experimentally using Escherichia coli Kl2$\delta$Hl$\delta$trp. A mathematical model describing the transient response to a step change in dilution rate was developed based on the assumption that the adaptation rate of cell growth is proportional to the available growth potential, which is defined as the difference in dilution rates between before and after shift-up. The kinetic parameters appearing in the model equations were the dimensionless step increase in growth rate($\alpha$) and the adaptation rate constant(k). These parameters were evaluated for various dilution rates and temperatures by washout method. This relatively simple adaptation model could predict the specific growth rate of the second-stage successfully. Advantage and disadvantage of the proposed model are also discussed.

Since the 18th century the museums in Europe have accepted the social demand of the publicity and have played a role of social education and it lasted to the present. Recently, the society began to change it's direction. It is from the Universalism to the Pluralism. The Universalism is due to democratic society after 'the Civil Revolution' and standardized social system after 'the Industrial Revolution' The Pluralism that starts with the decrease of the modern society is about the diversity and the activation of identity which has been disregarded since the Modernism. This study is to analyze and to clarify how the museum's educational environment which had begun since the 18th century has been changed since 1990 and how these are related to the social alteration from the Universalism to the Pluralism. As a result of this study, it was confirmed that there had been a simple circulation system and a unified spatial experience in the museum of Europe since 18th century to 1980's(phl) while there had been a complex circulation system and a diverse spatial experience in the museum of Europe after 1990's(ph2). These mean that the museum of phl gave a unified social education to the visitors and they came to have a similar knowledge and emotion after their seeing the exhibition material while the museums of 'ph2' gave a diverse one and the visitor came to have a different knowledge and emotion to the same exhibition material. The museum which gives a unified social education is to produce a unified thoughts of people and it is because the social direction is the Universalism. In addition to this, the museum of diverse social education is to produce people of diversity and it is related to the Pluralism.

In mobile communications environment, STBC-OFDM(Space Time Block Code-Orthogonal Frequency Division Multiplexing) system with transmit diversity obtains the MRRC(Maximal Ratio Receiver Combining) diversity gain in time-invariant channel between two received symbols. But in time-variant channel, due to the interference between received symbols, MRRC diversity gain cant be obtained. So, when the mobile device with transmit diversity moves in high speed, the scheme to reduce the performance degradation due to the interference is needed. In this paper, we propose the receiver architecture with advanced transmit diversity, which improves the performance of STBC-OFDM system. The proposed architecture obtains the diversity gain without the change of transmit bandwidth at the receiver with the interference canceller using ZF(Zero Forcing) algorithm. Simulation results show performance improvement as doppler shift is increasing.

With the global paradigm shift towards climate change, the shipbuilding industry is also considering propulsion systems that utilize eco-friendly fuels various propulsion systems are gaining attention as a result. In conventional propulsion systems, typically consisting of propellers and rudders, have evolved into a diverse range of systems due to the development of a special propulsion system known as the azimuth thruster. While azimuth thrusters were previously commonly installed on tugboats, they are now extensively used on offshore plant operation ships equipped with dynamic positioning systems. However, these azimuth thrusters require different steering methods compared to conventional propulsion systems, leading to a significant learning curve for the crew members boarding such vessels. Furthermore the availability of education related to these special propulsion systems is limited. This study aims to analyze accidents caused by inadequate control of vessels equipped with azimuth thrusters using the STAMP technique. And it proposes the necessity of standard steering commands for the safe operation of vessels equipped with special propellers.

Recent trends in urban policies show the increasing importance of urban parks. Moreover the park policy and planning are increasingly important for the good urban park system. Comparative studies in the operational system and planning contents of the parks and green space plans of the major cities would be timely and meaningful. This study aims to provide a comparative study in operational system and planning contents of the Parks and Green Space Master Plan at urban scale. Sites include London, New York, Berlin, Sydney and Seoul. Analyses are focused on the master plans and strategy reports of each city. Frameworks for analysis are divided into operational system and planning contents. The results are as follows. First, the Parks and Green Space Plans as an open space planning linked to related resources would contribute to both integrated resources management and practice of the fairness. Second, evolution from quantity to quality of the parks and green space plan enhances revitalization and regeneration. Third, shift from the 'supply oriented plan' to 'need based plan' model provides flexible planning model to meet the demographic change, trend change, preference and use. Fourth, planning agents, enlarged opportunities for participation within each phase, diversified of the participants lead the changes from the passive participation to active one. In order to improve the practicability of the parks and green space master plan, a flexible planning strategy including social awareness changes and park governance is required.

This study is trying to suggest the continuity and changes that would be made in inter-Korean military negotiations in the future under the Kim Jeong-eun regime by analyzing the recent inter-Korean Working-Level Talks for Gaeseong Industrial Complex based on 'anti-Japanese guerilla style negotiation model, the military negotiation model under Kim Jeong-il era. Especially, through analysis of the inter-Korean Working-Level Talks for Gaeseong Industrial Complex, it is verified that behavior similar to that in the military talks in the past is found even in the economic negotiations. Such analysis leads to an assumption that negotiations under the Kim Jeong-eun regime would be made within the category of the military negotiations under the Kim Jeong-il era. Fundamentally North Korea will change but try to achieve its objectives in the military talks within the existing frame of strategic culture rather than changing it. Such phenomenon will continue for some time. In the future inter-Korean military talks, however, North Korea will try to change its behavior to cope with its financial difficulties. Accordingly, the South Korea's government will have to have paradigm shift toward inter-Korean military negotiations. Especially, Kim Jeong-eun's studying abroad in the past will make him change in the negotiations. At this moment, the South Korean government must make continuous efforts to induce dialogue and negotiation. In order to induce the North Korea to change, the development of economic norm logic with the united front applied in the strategic culture of military negotiation and the formation of a value system in the North Korea's military negotiation policy makers will lead to the creation of a new military negotiation framework.
