Abstract The high number of fatalities and damage to buildings in the areas most affected by the earthquake should affect how to build houses. Especially in the case of self-housing, the community’s trauma will immediately encourage them to increase the safety of their buildings. However, early studies do not confirm so. Although it looks pretty built concerning the earthquake, the number of self-help houses found in post-disaster construction shows that concern for structural safety is still below expectations. This paper examines how safety precautions affect the way people build their homes. We discussed current housing developments geared towards earthquake vulnerability in Indonesia and found that housing security, in general, is still far from expectations. Learning from many post-disaster cases informs us that we must take radical and massive action regarding housing schemes and building structures to reduce the toll caused by destructed weak houses under every hit of an earthquake.

Basic Prerequisite

An urban residential building from the second half of the 19th century and the start of the 20th century, the so-called tenement house, is a significant representative of the architecture of the developing urban fabric in Central Europe. The vertical and horizontal load-bearing structures of these houses currently tend to show characteristic, repeated defects and failures. Their knowledge may, in many cases, facilitate and speed up the design of the historic building’s restoration without compromising its heritage value in this process. The article presents the summary of the most frequently occurring defects and failures of these buildings. The summary, however, is not an absolute one, and, in the case of major damage to the building, it still applies that, first of all, a detailed analysis of the causes and consequences of defects and failures must be made as a basic prerequisite for the reliability and long-term durability of the building’s restoration and rehabilitation. An integral part of the rehabilitation of buildings must be the elimination of the causes of the appearance of their failures and remediation of all defects impairing their structural safety, health safety and energy efficiency.

The tangible and intangible value derived from the built environment is of great importance. This raises concerns related to the resilience of constructed assets to both human-made and natural disasters. Consideration of these concerns is present in the countless decisions made by various stakeholders during the decades-long life cycle of this type of physical asset. This paper addresses these issues from the standpoint of the engineering aspects that must be managed to enhance the structural safety and serviceability of buildings against natural disasters. It presents risk-informed performance-based parameterization strategies and evaluation criteria as well as design methods to embed differentiated levels of structural safety and serviceability of buildings against wind, snow, earthquakes and other natural agents. The proposed approach enables designers to assure the resilience and reliability of building structures against natural risks.

When space is limited, there is often conflict over land use such as agriculture, nature conservation, housing, business and commercial enterprise. More knowledge is needed about the substance of such conflicts and the way the various uses are handled and spatially organised. Using empirical material collected in Hållnäs, Sweden, and Sandnes, Norway, between 2009 and 2012, this paper addresses the potential conflicts and synergies between the different uses of land, with agriculture as a reference point. In combining and comparing the results from Hållnäs and Sandnes, the way in which relations differ between them are also scrutinised. Through planning documents, interviews with officials in public authorities, active farmers, non-governmental organisations (NGO) and field visits, case-specific land uses are identified in the two areas. The conflicting and synergetic relations between agriculture and other ways the land is used are identified and illustrated by schematic models. The results indicate that agriculture is both in synergy and in conflict with other land uses. In the cases investigated in this study, the primary areas of conflict are between agriculture and biodiversity, between agriculture and cultural heritage, and between agriculture and climate-smart initiatives in terms of dense building structures.

Financial self-help organizations can be found in many parts of the world, and the cities of Java are among the areas where they are particularly widespread. Since about the 1950s, interest in these institutions among anthropologists and development sociologists has increased considerably. Analyses of financial self-help organizations have most often focused on their economic or their social function; few scholars have pointed to their function as providers of security and identified self-help organizations as typical forms of local social security institutions. The main shortcoming of most of these studies is that they base their conclusions solely on an analysis of the financial arrangements provided by these self-help organizations, neglecting the accommodating practices that people undertake in order to fit the provisions of self-help organizations to their own household needs. This essay explores the observation that financial self-help organizations do not simply provide security through the different kinds of insurance mechanisms they might contain, but that, particularly through the way in which people use them and participate in them, these institutions become meaningful for coping with insecurity. It examines the question of whether participation in financial self-help organizations contributes to the ability of households to cope with adversities and deficiencies in a concrete social context. Research aiming to answer this question was conducted in Bujung, an urban ward on the outskirts of Yogyakarta, on the island of Java.

The detection of cracks is a crucial task in monitoring structural health and ensuring structural safety. The manual process of crack detection is painstakingly time-consuming and suffers from subjective judgments of inspectors. This study establishes an intelligent model based on image processing techniques for automatic crack recognition and analyses. In the new model, a gray intensity adjustment method, called Min-Max Gray Level Discrimination (M2GLD), is proposed to preprocess the image thresholded by the Otsu method. The goal of this gray intensity adjustment method is to meliorate the accuracy of the crack detection results. Experimental results point out that the integration of M2GLD and the Otsu method, followed by other shape analysis algorithms, can successfully detect crack defects in digital images. Therefore, the constructed model can be a useful tool for building management agencies and construction engineers in the task of structure maintenance.

Benjamin Franklin grew up in a devout Protestant family with limited prospects for wealth and fame. By hard work, limitless curiosity, native intelligence, and luck (what he called “providence”), Franklin became one of Philadelphia’s most prominent leaders, a world-recognized scientist, and the United States’ leading diplomat during the War for Independence. Along the way, Franklin embodied the Protestant ethics and cultural habits he learned and observed as a youth in Puritan Boston. This book follows Franklin’s remarkable career through the lens of the trends and innovations that the Protestant Reformation started (both directly and indirectly) almost two centuries earlier. The Philadelphian’s work as a printer, civic reformer, institution builder, scientist, inventor, writer, self-help dispenser, politician, and statesman was deeply rooted in the culture and outlook that Protestantism nurtured. Through the alternatives to medieval church and society, Protestants built societies and instilled habits of character and mind that allowed figures such as Franklin to build the life that he did. Through it all, Franklin could not assent to all of Protestantism’s doctrines or observe its worship. But for most of his life, he acknowledged his debt to his creator, reveled in the natural world guided by providence, and conducted himself in a way (imperfectly) to merit divine approval. This biography recognizes Franklin as a cultural or non-observant Protestant, someone who thought of himself as a Presbyterian, ordered his life as other Protestants did, sometimes went to worship services, read his Bible, and prayed, but could not go all the way and join a church.

Construction insulation systems should provide solutions to the problems of creation of suitable conditions of load-bearing construction elements and whole construction, reduction of heat loss through thermal insulation layer, and creation of living comfort in buildings. The article presents the results of experimental studies, the purpose of which is to optimize the composition of extruded polystyrene foam, the formation of methods for selecting its composition and the development of systems for the use of products based on extruded polystyrene foam. Main provisions of the method of analytical optimization, which allows significantly reducing the material and time costs for processing the experimental results, are also provided. Aspects of the implementation of building systems using extruded polystyrene foam both from the point of view of minimizing heat loss through contact areas and the degree of influence of vapor permeability of building structures on the temperature and humidity conditions of premises are studied. Mandatory criteria for construction with the use of building systems are safety conditions, including both structural safety (including maintenance-free cycle) and fire safety.

<p>This paper aims to present the authors’ examination of some aspects of Vietnam’s positive law regarding non-judicial foreclosure. Upon default, a bank as a secured creditor may enforce his security right over the collateral that is understood as foreclosure. Foreclosure includes judicial foreclosure and non-judicial foreclosure. In the way of non-judicial foreclosure, a secured creditor can take possession and dispose the secured property without a court’s involvement. So, it may save the secured creditor time and cost. The law governing the non-judicial foreclosure should not only provide the efficient mechanics of self-help repossession but also protections to a grantor. It should be examined whether Vietnamese law meets this requirement. By this study, some drawbacks and shortages of Vietnamese law in relation to non-judicial foreclosure are exposed and then some recommendations for improvement of positive law of Vietnam governing the exercise of the non-judicial foreclosure are presented. </p>

The article presents the possibilities for the contemporary application of Styrofoam in the elements of building structures. Having in mind that Styrofoam belongs to a group of highly flammable materials, 5 % of combustion retarder - so called "retardant" - needs to be added to the amount when produced for structural building elements. That kind of Styrofoam is called "self-extinguishing" contrary to "normal" that does not contain that substance. The Article also shows the way in which building elements are constructed (external and interfloor construction), made out of Styrofoam using "Plastbau" technology. A possibility to use exterior wall panels ‘Plastbau’ under weather conditions of Saint-Petersburg has been considered. Temperature distribution along a wall’s section as well as a heat flow going through a building enclosure ‘Plastbau’ have been also analyzed herein.

Ex Post Analysis

The Balakot town and its surroundings were almost totally destroyed by Earthquake – 2005. The government has abandoned this town for residential purposes and declared as Red Zones Region. However, the government fully supported post disaster relief and restoration phases. The rehabilitation and reconstruction phases were carried out through community self-help-based system and partially supported by line agencies. This recovery is neither claimed by government nor desired by the community. It is the product of governments policy, interventions, local economic opportunities, and community self-help-based system. The present study will analyse each step of the recovery through study of the role of different stakeholders and its impacts on recovery process. All data sets are normalized and generalized with regression analysis. This study will generalize the complex process of recovery to reduce the risk of disasters.
