The formation of Chinese Town in Malacca of Malaysia and Singapore would explain that Chinese gradually played an important role of commerce and urban service according to the Western European advance to southeast Asia and the construction of colonial cities from the 16th century to 19th and massed residence in many cites of southeast Asia. Chinese was usually separated from the Western European by western colonial policy and city planning. Common architectural characteristics in Chinese towns of Malaysia can refer to the transmission of the Chinese architectural material, the combination of dwelling and commerce in a house and the space organization centered on a court or an air well in the narrow and long site, lying adjacent to street etc. The Chinese dwellings in Malaysia rooted with Chinese settlement in southeast Asia. The Chinese dwellings was not always a shop on 1th floor and a dwelling on 2nd floor before the 19th century. But as Chinese immigration and commercial activity progressed in earnest in the early of 19th century, the row house of Chinese for dwelling was autonomously changed to two functional shophouse for dwelling and commerce. Chinese row house can refer to the use of Malay regional material, change of symmetrical Chinese traditional housing type by the narrow and long site and the tendency of the eclectic elevation of Western and China. Another architectural characteristics of the shophouse is an appearance of the continuous verandah with a cover regulated by Stamford Raffles in Singapore. This regulation was applied to architecture in Chinese Town as Stamford Raffles constructed Singapore. It was spread to South China reversely and became the regulation of streetscape for the modern city. Shophouse of Chinese towns in Southeast Asia and south China can be understood by context of Chinese immigration, colonialism, housing type of commerce and dwelling and the Western European city planning.

The main objective of this study is to estimate the levels of pollution to which the community is presently exposed and to model the regimes of local air quality. Diurnal, daily, and monthly variations of NO, NO₂, SO₂, and O₃ were thoroughly investigated in three areas; namely, residential, industrial, and terminal in Ras Al-Khafji. There is obvious diurnal variation in the concentration of these pollutants that clearly follows the diurnal variation of atmospheric temperature and main anthropogenic and industrial activities. Correlation analysis showed that meteorological conditions play a vital role in shaping the pattern and transportation of air pollutants and photochemical processes affecting O₃ formation and destruction. Bivariate polar plots, an effective graphical tool that utilizes air pollutant concentrations' dependence on wind speed and wind direction, were used to identify prevailing emission sources. Non-buoyant ground-level sources like domestic heating and street transport emissions, various industrial stacks, and airport-related activities were considered dominant emission sources in observatory sites. This study offers valuable and detailed information on the status of air quality, which has considerable, quantifiable, and important public health benefits.

High-rise as a building typology is gaining popularity in Asian mega-cities, due to its advantages in increasing volumetric density with limited land resources. Numerous factors contribute to the formation of high-rise urban form, from economical and institutional, environmental to socio-political. Environmental concerns over the impact of rapid urbanization in developing economies demand new thought on the link between urban environment and urban form. Outdoor and indoor climate, pedestrian comfort, and building energy consumption are all related to and impacted by urban form and building morphology. There are many studies and practices on designing individual "green" high-rise buildings, but far fewer studies on designing high-rise building clusters from the perspective of environmental performance optimization.. This paper focuses on the environmental perspective, and its correlation with the evolution of the high-rise urban form. Previous studies on urban morphology in terms of environmental and energy performance are reviewed. Studies on "parameterizing" urban morphology to estimate its environmental performance are reviewed, and the possible urban design implications of the study are demonstrated in by the author, by way of a microclimate map of the iconic Shanghai Xiao Lujiazui CBD. The study formulates the best-practice design guidelines for creating walkable and comfortable outdoor space in a high-rise urban setting, including proper sizing of street blocks and building footprint, provision of shading, and facilitating urban ventilation.

The flow characteristics in the blade passage and in the wake region of a low speed axial flow fan have been investigated by experimental analysis using a rotating hot-wire sensor for design and off-design operating conditions. The results show that the tip leakage vortex is moved upstream when flow rate is decreased, thus disturbing the formation of wake flow near the rotor tip. The tip leakage vortex interfaces with blade pressure surface, and results in high velocity fluctuation near the pressure surface. From axial velocity distributions downstream of the fan rotor, large axial velocity decay near the rotor tip is observed at near stall condition, which results in large blockage compared to that at the design condition. Although the wake flow downstream of the rotor blade is clearly measured at all operating conditions, the trough of the high velocity fluctuation due to Karmann vortex street in the wake flow is mainly observed at a higher flow condition than the design flow rate.

This study was conducted to track the appearance of Aguijjim and its popularity on the national level. Furthermore, changes in the monkfish recipe and how they impacted the consumption of monkfish were investigated. It is assumed that monkfish was consumed by Japanese in Korea during the Japanese colonial era. After liberation, people cooked the fish as soup. In the 1960s, Aguijjim was invented in Masan. There is great controversy regarding how the dish was born. It has been asserted that it was created by one specific person, that refugees with insufficient food developed, and that it is just an advancement of Bugeojjim. Aguijjim restaurants began to appear in Seoul in the 1970s, and in the 1990s streets full of Aguijjim restaurants formed. Moreover, popular music and literature referenced Aguijjim in the late 1990s. As Aguijjim has developed and the formation of Aguijjim street have combined, the consumption of monkfish has increased drastically, leading to its import. As cooking methods have transformed, the fish with the unpleasant look which was thrown out in the past, have dramatically gained public interest. 'Masan Aguijjim' became an independent brand that represents a local food that has also been nationalized in a short amount of time.

The process and efficiency of monitoring building and construction violations is a concern of the construction industry. The detection of violations requires appropriate and sufficiently accurate spatial information to manage and support a comprehensive inspection process and monitor compliance. A building inspection workflow must extract appropriate spatial and measurement in-formation from a variety of sources, identify potential violations across a range of compliance criteria and determine the quality of resulting inspection reports. This paper presents a framework for supporting building inspections using spatial information and methods to detect construction violations and compliance. Current inspection processes involve issues around the identification of building violations, access to building regulations and existing spatial information, integration of a range of spatial and non-spatial information, and the quality of decisions within the inspection workflows. A survey of building inspectors was conducted and used together with the issues identified to establish the requirements for a spatial inspection framework. The results demonstrate how such a framework can support improved decision-making and reduced fieldwork effort in detecting and measuring the accuracy of building violations involving building placements, street offsets and footprint areas.

This study, as part of a study on the visual impact and evaluation of the symbolic sculptures currently installed in counties in Jeollanam-do on the formation of Landscapes by local governments, investigated and analyzed the installation characteristics of symbolic sculptures by local governments. As a result, many local governments have installed local specialties and landmarks as symbolic sculptures, and the installation location is often installed in open spaces and in the center of roundabouts. It was investigated that the use of color or the color of the material as it is was preferred. It was found that more symbolic sculptures installed on the roadside were installed in the center of the roundabout or along the side of the street than installation at the gateway. It is considered that it is more effective to recognize the symbolism of the area to the tourists through the installation of the symbolic sculpture at the entrance of the area, the center of the roundabout, or the side of the road rather than the gate, because the size of the symbol is bigger in order to recognize the symbolism of the area due to the width of the large road when installing the symbolic sculpture at the gateway, It is considered.

Unlike a slender body, vortices are shed off alternately in the wake of a blunt body. In the case of liquid flows, when the pressure falls below the vapor pressure, cavitation occurs in the vortex core and affects the formation of the vortex street. This phenomenon is of major importance in many practical cases because the alternate shedding of vortices creates imbalanced forces on the body. Hence, it is very important to determine the shedding frequency of cavitating vortices. In this paper, the unsteady cavitating flow around a two-dimensional wedge-shaped submerged body was simulated using the commercial code STAR-CCM+. A numerical investigation of the structure of cavitating vortices was performed for a model with an apex angle of $20^{\circ}C$. The results were validated by comparing them with experimental measurements carried out at a cavitation tunnel of Chungnam National University (CNU-CT). It was found that the shedding frequency of the vortex increased by up to 18%, which was strongly affected by the development of cavitation.
