Street art comprises all kinds of art developed in public locations. This form of art has spread to all heritage streets in George Town, the capital of Penang Island, which is also a known UNESCO World Heritage Site. However, instead of its heritage, food, and interesting past life and structure, the rapid multiplication of street art in George Town has created a new and unusual art that attracts tourists. Street art has spread to small roads and heritage streets in the city. This art increases the awareness of spectators by introducing them to the rich history of these streets and inducing a lively concept in the inner city of George Town. Accordingly, the impact of iron rod sculptures and murals, which comprises approximately 90% of street art in George Town, were determined to explore and identify the effects of this street art on this world heritage site. The findings were obtained from 263 out of 306 questionnaires accomplished by tourists in George Town. The results confirm that tourists prefer murals over iron rod sculptures. Iron rod sculptures are designed to tell the history of the street, whereas murals are designed to create aesthetic value. The findings indicated that similar to iron rod sculptures, more control should be exercised on the subjects of murals.

In order to limit the infiltration of outdoor air pollutants, a positive indoor air pressure should be maintained. This study aims to investigate the minimum mechanical ventilation rate to achieve a positive indoor air pressure for large space buildings with different kinds of envelopes. The types of building envelope include envelope with multilayer windows (which generally appears in shopping malls and open-plan office buildings), envelope with entrances on the first floor and multilayer windows, and envelope with openings at bottom and top levels (which generally appears in industrial plants). It is concluded that the minimum ratio between mechanical ventilation and initial infiltration rates to achieve a positive indoor air pressure depends on the window width-height ratio, the vertical spacing between windows, and the number of window layers. More regulations are summarized and analysed to guide the ventilation design.

This research examines and proves this effectiveness connected with artificial neural networks (ANNs) as an alternative approach to the use of Support Vector Machine (SVR) in the tourism research. This method can be used for the tourism industry to define the turism's demands in Iran. The outcome reveals the use of ANNs in tourism research might result in better quotations when it comes to prediction bias and accuracy. Even more applications of ANNs in the context of tourism demand evaluation is needed to establish and validate the effects.

<p>Small islands are seen as iconic destinations for ecotourism due to their rich natural biodiversity and spectacular surroundings. Malaysia has a substantial number of islands, numbering approximately 878 islands. Pangkor Island is a popular destination among domestic and international tourists alike. However, the tourism industry can be a double-edged sword. On one hand, tourism development can improve quality of life and economic prospects of local communities; and on the other hand, it may inflict to destruction on the island’s sensitive ecosystem. Natural environment is the core attraction for Pangkor Island. However, the extensive development undertaken to match the high intensity of tourist arrivals can lead to deleterious effect on the natural environment and diminish the overall quality of the tourists’ experience. This paper attempts to explore the dichotomy between ecotourism concept and tourism development in Pangkor by exploring protection strategies and ecotourism management approaches in relation to Pangkor Island. The findings described in this paper are based on an evaluation of the existing planning strategies concerning tourism development, environmental conservation, observation and interviews with visitors in Pangkor Island. Lack of environmental practice among tour operators has led to significant threat to the island’s ecosystem. Consequently, Pangkor Island require imperative attention in ensuring the sustainability of the ecosystem. Planning and development strategies for managing Pangkor and adjacent smaller islands need to be taken into consideration by acknowledging baseline conditions and present day realities.</p>
