IDENTIFYING THE OPERATION MODE PROBLEMS OF DILAPIDATED URBAN HOUSING RENEWAL SYSTEM IN ZHEJIANG, CHINA: CASE STUDY OF JINSHOU PROJECT IN ZHOUSHAN

The high rate of migration, coupled with population increase triggered rapid urbanization. However, a great proportion of the population still lives in substandard and low quality houses in a deplorable unsanitary residential environment particularly in developing countries. Urban and Economic growth have brought about all typical problems associated with rapid urban development resulting in housing shortage both quantitative and qualitative, slums, illegal settlement and squatting as experienced in owerri municipality. These have resulted into many urban and housing problems within the state capital owerri. This study examined the nature of urban growth and housing problems in owerri municipality. Also it tries to examine residential housing stock, identity the nature of housing problems, government policies and programmes in other to address the problems. The pattern of growth was determined using spatial analysis, and the housing problems were identified through questionnaire and field surveys. Findings revealed that the growth of urban housing in owerri municipality increases by 1034.0 hectare which is equivalent to 38.5% which is in line with Maurice (2004). It was also discovered that over a period of time, new settlements have evolved. Also, the construction and expansion of road networks are evidences of urban growth in owerri municipality.

Fundamental Reason

As the two most important modes in public transportation, the coordinated development of bus and metro networks significantly influences the efficiency of public transportation. However, two parallel bus and metro lines belonging to different operators may lead to supply competition and consequently yield over-supply. Taking two parallel bus and metro lines in Harbin city, China as a case study, this paper, drawing on game theory, establishes a utility model based on the two lines’ frequencies, and reveals and explains the fundamental reason for the over-supply problem using a Nash equilibrium. In an attempt to resolve this issue, the study proposes a new operation mode: integrating frequencies of the two modes to obtain larger total profits then reallocating the total profits to the two modes. The case study shows that this new operation mode can effectively solve the over-supply problem while satisfying both operators of the two modes, and hence having practical value.

Housing Renewal

Since the 1970s, the South Korean government has been redeveloping blighted residential environments and adopting large-scale redevelopment policies to solve urban housing-related problems. However, it is difficult to designate areas for redevelopment and identify areas where redevelopment is currently unfeasible. This study establishes a framework to support decision-making in a selection of housing renewal districts. The proposed Residential Environment Maintenance Index (REMI) overcomes the limitations of existing indicators, which are often biased toward physical requirements. Using this, we rationalize the designation of maintenance areas by considering both physical and social requirements and outline the renewal district designation procedure. To derive REMI, we used an analytic hierarchy process analysis and estimated the index’s reliability by clarifying the relative importance and priority of the indicators based on surveys of 300 subject matter experts. We analyzed various simulations by applying REMI at sites where maintenance is currently planned or discharged in Seoul. These reveal that the total number of urban renewal projects can be adjusted by adjusting the number of renewal district designations through the proposed REMI according to the economic situation. The results have implications for understanding REMI’s possible application and flexible management at the administrative level to pursue long-term sustainable development.

Definition Of

Many processes to produce fine chemicals and precursors of pharmaceuticals are still operated in batchwise mode. However, recently, more producers have taken a change to continuous operation mode into consideration, performing studies and trials on such a change, while some have even already exchanged their production mode from batchwise to continuous operation. In this paper, the stepwise development from an initial idea to industrial implementation via laboratory testing and confirmation is revealed through the example of an organic fine chemical from the perspective of a crystallization plant manufacturer. We begin with the definition of the objectives of the project and a brief explanation of the advantages of continuous operation and the associated product properties. The results of the laboratory tests, confirming the assumptions made upfront, are reported and discussed. Finally, the implementation of an industrial plant using a draft tube baffled (DTB) crystallizer and the final product properties are shown. Product properties such as crystal size distribution, crystal shape, related storage stability and flowability have successfully been improved.

Irish Free State

ABSTRACT:At its inception, the Irish Free State faced an apparently intractable housing problem that required immediate action. This article examines the legislation enacted in the 1920s and 1930s, focusing on its impact on local authority housing in Ireland's provincial towns. Whereas the 1932 Housing Act has generally been heralded as the start of a concerted attack on the slums, this assertion is re-evaluated in the context of the debates of the 1920s. Following an overview of the national situation, a case-study of Ballina, Co. Mayo, explores the impacts of the housing drive. State-aided housing schemes made a significant contribution to the housing stock between 1923 and 1940. Although characterized by contemporary media as a triumph, however, the housing drive raised many issues including build quality, costs, opposition and social segregation. The article considers some of these challenges and raises a number of questions for future consideration.
