From the unprecedented 2011 spring flood, the residens reside by Lake Champlain and Richelieu River encountered enormous damages. The International Joint Committee (IJC) released the Lake Champlain-Richelieu River (LCRR) Plan of Study (PoS). One of the major tasks for the PoS is to investigate the possible scenarios that might happen in the LCRR basin based on the stochastic simulation of the Net Basin Supplies that calculates the amount of flow into the lake and the river. Therefore, the current study proposed a novel apporach that simulate the annual NBS teleconnecting the climate index. The proposed model employed the bivariate empirical decomposition to contamporaneously model the long-term evolution of nonstationary oscillation embeded in the annual NBS and the climate signal (here, Artic Oscillation: AO). In order to represent the variational behavior of NBS correlation structure along with the temporal revolution of the climate index, a new nonstationary parameterization concept is proposed. The results indicate that the proposed model is superior performance in preserving long and short temporal correlation. It can even preserve the hurst coefficient better than any other tested models.

Inclusive innovation refers to different types and forms of innovation activities or performance by which we can get more for lesser cost and which could cater and meet the needs and demands of more people. The essence of inclusive innovation is to help poor, marginalized and underprivileged sections of society to improve their livelihoods and enable them to climb up the socio-economic ladder. In the current phase of economic slowdown, increasing unemployment and inequalities, World Bank, OECD and various governments are turning towards inclusive innovation as a new source of optimism or even as a new innovation strategy. Whilst it is being reframed or packaged as a novel or a new strategy, one can trace its historical roots to the AT movement and the Gandhian ideas of economy and society in the 1940s and 1950s. These ideas have inspired and influenced a range of individuals, institutions and civil society groups in inclusive innovation.

A free vibration analysis is made of a moderately-thick toroidal shell based on a shear deformation (Timoshenko-Mindlin) shell theory. This work represents an extension of earlier work by the authors which was based on a thin (Kirchoff-Love) shell theory. The analysis uses a modal approach in the circumferential direction, and numerical results are found using the differential quadrature method (DQM). The analysis is first developed for a shell of revolution of arbitrary meridian, and then specialized to a complete circular toroidal shell. A second analysis, based on the three-dimensional theory of elasticity, is presented to cover thick shells. The shear deformation theory is validated by comparing calculated results with previously published results for fifteen cases, found using thin shell theory, moderately-thick shell theory, and the theory of elasticity. Consistent agreement is observed in the comparison of different results. New frequency results are then given for moderately-thick and thick toroidal shells, considered to be completely free. The results indicate the usefulness of the shear deformation theory in determining natural frequencies for toroidal shells.

The existing urban open space system of the German cities has an exellent frame, which is a result of the long history of its developing. The beginning time of that goes back to the end of the 18th century, as pri-vate gardens of feudal lords and the nobility became more and more public and public open space plannedwas appearing. Through the change from the feudal age to the civil society, the people's values on the urbanopenspace were growing. so that it had more social meanings. Since the Industrial Revolution in the secondhalf of the 19th century the environment of cities was getting miserable, what was the important cause ofthe birth of ideas and concepts of the urban open space type and its system.The fo1lowing concepts are they. which have influenced modern open space concepts of the cities InGermany decisively :'Garden Cities'.'Neighborhood'. 'The Model of Mohring, Eberstadt and Petersen','The Model of Langen'. "The Classified City','The Classified and Loosened City'etc.

In this study, we evaluated the energy production from plant-microbial fuel cells using representative indoor plants, such as Scindapsus aureus and Clatha minor. The maximum power density of microbial fuel cell (MFC) using S. aureus ($3.36mW/m^2$) was about 2 times higher than that of the MFC using C. minor ($1.43mW/m^2$). It was confirmed that energy recovery is possible using plant-MFCs without fuel. However, further research is needed to improve the performance of plant-MFCs. Nevertheless, plant-MFCs have proved their potential as a novel energy source to overcome the limitations of the conventional renewable energy sources such as wind power and solar cells, and could be employed to a power source for the sensor in charge of the fourth industrial revolution.

In the era of the 4th Industrial Revolution, smart technology being considered to improve productivity breakthroughs is in the spotlight as a means to replace traditional construction technology in the construction industry. However, various problems are occurring in construction sites using smart technology and causing negative impacts on construction projects. Therefore, the objective of this study is to identify risk factors that occur when smart technologies are used in construction projects. To achieve this purpose, this study investigated the difficulties at construction projects using smart technology, and risk factors were derived based on site surveys and literature. The risk factors were measured by experts, and then a total of 19 risk factors was derived by exploratory factor analysis. As a result, risks were classified as 5 factors, the institutional factor is the most difficult response, and the government needs anticipative system improvement and a long-term plan. The research findings provide practical implications for construction experts trying to apply smart technology in construction sites and construction policy-makers to revitalize smart technology.

The trust issue on the safety of autonomous vehicle is a very important in regard to the demand generation of relevant industries. To secure the trust, The study of legal liability issue should be prior to an accident of the autonomous vehicle. In civil law, it is possible to make the automobile manufacturer take legal responsibility with the "Product Liability Act". Whereas, in criminal law, it is difficult to make him take legal responsibility since the criminal law holds the actor responsible. To solve these problems, this article proposes the establishment of the "Special Act on Autonomous Vehicle". Also, there is a demand for building infra structures and system to operate the (fully) self-propelled vehicle and establishing "certification" systems.

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.
