Residential Satisfaction Among Public Housing Residents Living in Social-Mix Housing Complexes: The Case of the Seoul Metropolitan Area,Korea

Abstract

This study asks how a social mix policy that mixes public housing with private housing in the same housing complex is associated with residential satisfaction among public housing residents in Korea. We also ask if mixture types between public and private housing make a difference in the residential satisfaction of public housing residents. By analyzing the 2011 Korea Housing Survey for Public Housing Residents, we find that living in the independent type that includes only public housing and the random-mix type that randomly mixes public housing with private housing in the same building is positively related to residential satisfaction among public housing residents. The empirical analysis also shows that the levels of social conflict among residents are the lowest in the random-mix type.     

Social Belonging,Social Capital and the Promotion of Home Ownership: A Case Study of Hong Kong

The Hong Kong Government is vigorously promoting home ownership, a major rationale being to increase the community's sense of belonging and reduce the rate of emigration. This paper evaluates whether home owners in Hong Kong have a higher sense of social belonging than renters and finds that tenure status is a spurious independent variable in assessing respondents' sense of belonging to Hong Kong. Logistic regression analysis suggests that the significance of tenure is greatly reduced when other variables, namely age, identity, income and foreign abode right are controlled. The analysis also shows that those possessing a comparatively high sense of social belonging tend to bear the identification of Hong Kong Chinese, be older, have high incomes, and hold no foreign right of abode. Of the control variables, the factor of 'identity' appears most influential. Hong Kong's relationship with China, the uncertain nature of a Hong Kong identity and the territory's economic trajectory as a higher order services economy has meant that housing policy, specifically the promotion of home ownership, is perceived by the government as influencing values and behaviour very narrowly defined as promoting social belonging primarily in a territorial or geographical sense, with wider implications of neighbourhood stability unconsidered.     

The prediction of wind- induced responses of the new Hongkong and Shanghai Banking Corporation headquarters,Hong Kong

An extensive wind engineering programme has been undertaken for the Hongkong and Shanghai Banking Corporation headquarters project. As part of the study the fluctuating aerodynamic forces on a light rigid model of the new building have been measured using the force balance technique.This paper describes how these measurements have been used to predict the overall dynamic response of the building in order to verify the design for strength and to check the performance of the building against criteria for deflection, occupant comfort and fatigue.

Deterministic and reliability analysis of prestressed concrete bridge girders: comparison of the Chinese, Hong Kong and AASHTO LRFD Codes

This paper compares the prestressing requirements and reliability indices of prestressed concrete bridge girders designed using three codes: the Chinese Code, the Hong Kong Code and the AASHTO LRFD Code. Typical post-tensioned concrete girders of spans ranging from 25 to 40 m are considered. Deterministic analysis indicates that the service limit state governs the design according to the Chinese Code and the AASHTO LRFD Code. However for the Hong Kong Code, only those with longer spans are controlled by the service limit state. The actual number of strands needed by the AASHTO LRFD Code is quite close to that needed by the Chinese Code, while that required by the Hong Kong Code is about 18–33% higher than that required by the AASHTO LRFD Code. Disparity between reliability indices for flexural capacity based on the requirements of the service and strength limit states exists in all three codes. However, the disparity does not follow the same trends as that of the required number of strands for service and strength limit states in the three codes. In addition, the reliability index for flexural capacity according to the requirements of the service limit state is always higher than that of the strength limit state in the three codes. The actual reliability indices for flexural capacity of the girders considered according to the three codes, which are governed by the service limit state, are close to one another.

Distribution patterns of polycyclic aromatic hydrocarbons (PAHs) in the sediments and fish at Mai Po Marshes Nature Reserve, Hong Kong

Sediment samples were collected monthly from eight shrimp shallow ponds (local name gei wais) from July 2003 to January 2004, and from mangrove swamps and inter-tidal mudflats in July and November 2003, respectively. Fish samples (tilapia) were also collected. Polycyclic aromatic hydrocarbons (PAHs) were analyzed by gas chromatography and mass spectrometry (GC/MS). The results indicated that under wet season wet deposition and suspended particulates brought in by nearby rivers, such as the Peal River, served as an important source of PAHs entering Mai Po Marshes. Total organic matter in the sediments showed significant correlations (p<0.01) with PAHs in the sediments, mainly due to the mechanism that organic matter such as humic substances increased PAH persistence by binding and occluding PAHs. Except for naphthalene, biota-sediment accumulation factors (BSAF) of the PAHs in tilapia were below 1.7, which may be caused by biotransformation and the lower uptake in fish. In addition, aqueous route dominated accumulation of non-biodegradable PAHs in tilapia because higher levels were detected in larger fish than in smaller ones. A general trend was observed that BSAFs declined with the increase of K(ow) values, which suggested that bioavailability of low K(ow) isomers was high due to higher gill transfer efficiencies (aqueous uptake) in fish but enhanced biotransformation and decreased gut assimilation (dietary uptake) resulted in decreased accumulation of more hydrophobic PAHs (high K(ow)). Lastly, viscera appeared to be a promising tissue for biomonitoring, as it contained much higher concentrations than the muscle (3.5 magnitudes), and the levels in the muscle were significantly correlated with those in the viscera (r2=0.938, p<0.0001).     

A Study for the Fire Safety Planning of the Himeji-jo Castle, Main Tower

Himeji Castle (Himeji-jo) is a Japanese National Treasure and an UNESCO World Cultural Heritage site. The castle is visited by a large number of visitors, around one million every year and a maximum of 9,000 in one day. Experiments on a 1/25 scale model are carried out to grasp the feature of smoke movement within the main tower, so as to improve life safety and mitigate damage to the building in case of a fire. The Froude number is considered for similarity, and the movement of smoke is visualized. The experiments demonstrate certain interesting effects resulting from the architectural features of the castle; in particular, deep soffits on the lower stairs, along with tall windows, which are generally left open during the day, can significantly reduce the risk of smoke penetration to the upper-level stairs. The tests produced detailed data on the distribution of smoke in different fire scenarios, particularly the zones that are unaffected and inundated by smoke. Integration of these results with the evacuation characteristics of the building will be an essential part of functional safety planning for the castle.

Pilot testing of manganese oxidation in a high-rate sedimentation process for the reprovisioning of the Sha Tin water treatment works, Hong Kong Special Administrative Region

The Sha Tin water treatment works (STWTW), Hong Kong Special Adminstrative Region, was commissioned in 1964 with an initial treatment capacity of 364 million litres per day (MLD). Since then it has undergone three stages of expansion to reach the current nominal capacity of 1227 MLD. The plant is in need of an in situ reprovisioning. The challenge is to complete the reprovisioning while maintaining a minimum output of 900 MLD, with any shutdown to be limited to 8 h generally. With the site already fully utilised, the key to success is to first replace the conventional low‐rate sedimentation process with high‐rate robust processes to free up the much needed space. Among other requirements, the chosen process must also be capable of treating water with variable turbidity and removing spikes of manganese effectively. The project team conducted a 4‐month pilot testing programme with an Actiflo^® high‐rate pilot plant and the key results are described.
