Do you have culture shock? What is the one thing that you find most difficult to adjust to? Being of Chinese origin, I would not say that I really suffered from culture shock. However, it took some time for people to understand why I don’t speak Cantonese while I say I am Chinese. Mobility is also limited because of the language barrier, but only in the beginning.

On the courses I studied, we received international lecturers from the UK, Australia and Singapore. This was in addition to guest lecturers from within the engineering profession in Hong Kong, such as engineers from government departments and an international engineering consultancy.

What are the advantages and disadvantages of being an international student? • Being an international student meant that I brought with me a set of experiences from where I had studied and worked previously. So while not being familiar with Hong Kong student life was a challenge to be met, this was an exciting challenge which was about discovering a new student WILLIAM LOASBY experience and seeing my previous experience from a new MSc (Eng) in Structural Engineering - graduated in January 2009 perspective.

Disadvantages: • It is quite difficult to make friends with local students. • Because of the use of two languages in Hong Kong, it is difficult to communicate with people (in the street but even at the university) since many people don't speak English. And even if university students speak English, they only use Cantonese when they are together so it is easier to make friends with other exchange students.

Do you have culture shock? What is the one thing that you find most difficult to adjust to? Of course, when going abroad there is a culture shock. Personally, I think that the way to work/study in France and in China (HK) is totally different, sometimes I don’t really understand why people are dealing with some problems in that way since I would have done in a totally different manner. This is especially true for team project. XAVIER DEMEULENAERE BEng (Mechanical Engineering) - year three Career aspirations – what is the dream job after HKU?

What are the advantages and disadvantages of being an international student? Advantages: • I have a different way to see/understand the things because I don’t have the same background/culture. • I can learn a new culture. • I have the opportunity to meet a lot of other exchange students from all over the world. • I have the opportunity to improve language skills (improve English in my case since it is not my mother tongue, however learning Chinese is very difficult).

Tips on leading a happy student life as an international student • Be open-minded and try to discover the new culture. • Try to make some local friends to have an inside look at HK life (I guess joining a hall sport team is a good way to know some other students). • Like many exchange students, try to travel a little bit (or a lot!) to enjoy your stay in Asia since one can find very cheap and beautiful destinations. important because between all the studying and working you have to relax and there is no way better than doing it with friends.

The second one is sailing, I love to sail in Holland. I was a sailing instructor and I loved spending time on the water. In Hong Kong I have not sailed that much but, it was really nice the times I did because Hong Kong weather is much better than Holland.

The third is watching a movie. I like watching movies - it is a really good way to get away from all the things around you and relax for two hours.

Why Hong Kong? Why HKU Engineering? That’s an easy answer for me because I moved here with my family. My parents and brother also moved here. It is a nice country to live in, nice weather most of the time so many possibilities to do stuff you like or to try new stuff or of course food. And it’s totally different and because if you try something VAN DE LAAR different you always find something new. BEng (Industrial Engineering & Technology Management) - year two Department of Industrial and Manufacturing Systems Engineering HKU is a great university where you can learn a lot. Not only to get your degree but also things you can use for the rest of your Country of origin: The Netherlands (Holland) life.

How many years have you lived in Hong Kong? And how Since I was a little kid I had a thing for technology. I always many years at HKU Engineering? wanted to know how things worked, how they were made. And I have been living in Hong Kong since August 2008. Almost one I still want to know the answer on those questions but now I year at HKU Engineering. also want to know how I can do or make things like that myself. And that’s why I’m here. Here in Hong Kong and here in HKU Three things you like most about studying at HKU Engineering Engineering. • Many international students. • A lot of activities and field trips. • Starbucks on campus.

Advantages: • When you are an international student you learn more during your classes, you also learn a new culture, improve your language skills, and make new international friends.

Disadvantages: • As an international student, it can be difficult to understand jokes people make especially when they do it in Cantonese.

Also Hong Kong is 24/7 there is always something to do even on Sunday (In Holland almost everything is closed on Sunday).

Career aspirations - what is the dream job after HKU? That’s a really difficult question because I don’t know yet. There are so many possibilities but one thing I’m sure is that it has to be something with technology and people.

Interest/Hobbies: My first hobby is spending time with friends. I think this is really F EATURE : Profiles of internaTional stAFF

Career aspirations - what is the dream job? To become a worldwide leader in my research area, internationally recognised for my contributions.

Interest/Hobbies Perhaps it is not good, but my job is probably my first hobby (never stop thinking about it). I also like to run and play the piano.

Why Hong Kong? Why HKU Engineering? My case is special as I am here mainly for family reasons (my wife is Chinese). Nevertheless, Hong Kong is well-known for its good DR GRAZIANO CHESI universities, in particular HKU Assistant Professor which is officially one of the top Department of Electrical and Electronic Engineering universities in Asia. There are many talented people in HKU Engineering Country of origin: Italy who are recognised worldwide.

How many years have you lived in Hong Kong? And how many years at HKU Engineering? Three years (I joined HKU Engineering when I came to Hong Kong). Tips on leading a happy teaching life as a foreign teaching staff • Stimulate students' curiosity (inventions are found by curious Three things you like most about teaching at HKU Engineering guys). • I teach my own research. • Push students to verify what they learn (we never stop to • Students from different departments can take my course (valid understand a subject). for research postgraduate courses). • Spend a few minutes to entertain students (in my case I share • Organisation and facilities are very good. with them something about Italy!).

What are the advantages and disadvantages of being a foreign teaching staff? Advantages: • Students may be interested (or at least curious!) in attending lectures taught by a foreigner.

Disadvantages: • I cannot communicate with the students in Chinese (not yet!)

Do you have culture shock? What is the one thing that you find most difficult to adjust to? Not really. I guess that I have been helped by the fact that my wife is Chinese. The thing I find most difficult to adjust to is probably the narrow space in Hong Kong. Career aspirations - what is the dream job? Being an academic is already a dream job for me. It gives me flexibility to do my research and I enjoy teaching.

Interest/Hobbies I enjoy hiking or walking on a nice winter day. Shopping in Mong Kok is another favourite. I'm not a big sports fan, but occasionally I like playing basketball.

Why Hong Kong? Why HKU Engineering? Hong Kong is a fun city to live in. Although its density sounds scary, you can easily escape within an hour to an outlying island or a mountain peak and be as close to the nature as if you were living in a tropical island. Density is also nice sometimes, DR NIKOS MAMOULIS especially on Sunday evenings watching the crowds streaming on Associate Professor the streets of Mong Kok or Causeway Bay.

Disadvantages: • Cantonese may be required for in-depth communication with students, as some prefer to discuss in their mother language.

Do you have culture shock? What is the one thing that you find most difficult to adjust to? Culture shock? Not really. It took some time to get used to HK, but it's not as bad as it may sound for someone from overseas. HK people are really friendly and help your way out in almost all circumstances where you might find yourself lost. Of course, you need to learn the language for everyday communication with common people.

I would say the most difficult thing to adjust to might be the environment, including weather and pollution. There is a lot of energy waste, energy-inefficient buildings, energy- inefficient lifestyle (e.g., air-conditioners switched on everywhere, even in the middle of the winter). 5 12 SICHUAN EARTHQUAKE

ring Reconstruction of Zheng Dong Jie Kindergarten ee in Chongzhou, Sichuan Province

Civil Engin n May 12, 2008, a massive earthquake hit the Sichuan OProvince, which resulted in the total destruction of the Zheng Dong Jie Kindergarten in Chongzhou. The building had a history of 80 years.

“Operation Concern”, a Hong Kong charitable organisation, has raised HK$5 million to assist the Chongzhou community to rebuild the kindergarten at the existing site. They have also invited the Department of Civil Engineering of The University of Hong Kong (the department) to assist in the project.

City ventilation of Hong Kong Prof Yuguo Li, Derpartment of Mechanical Engineering

entilation of a city defines the ability of removing airborne Vpollutants and heat from a city. High-rise buildings, typically 40–60 stories, are “packed together”, along the 17 km long northern shore of Hong Kong Island, presenting one of the most beautiful high-rise skylines in the world and also a challenging city ventilation problem. The east-west principal An infrared photo of the surface temperature profiles of Hong Kong on street urban morphology coincides with the easterly prevailing 15 March 2008 16:00. The color scale indicates the surface temperature. winds in Hong Kong. The external air enters our city and carries It can be seen that some building surfaces are much warmer than others. We suggest that the warmer building and mountain surfaces than ambient away airborne pollutant and heat generated in the city. air create upward buoyancy flows to drive natural ventilation of the city.

One interesting question is what happens during no-wind conditions in Hong Kong. Our hypothesis is that in the morning, quality in other cities. Rapid urbanisation is currently under the heating of the slope of the Peak Mountain produces upslope taking in the Mainland China. In 2000, there were 379 cities with flows, drawing air from the bottom of the slope where the city a population of > 100,000, 130 cities >1 million, 6 cities >5 is. At the same time, the exterior surfaces of high-rise buildings million. There are 40 billion m2 buildings in 2005 in China, and are also heated up and upward convection flows are produced. by 2020, 30 billion m2 more buildings will be built. At the same The ground level air in the city is presumably replaced by the time, 20 of the world's 30 most polluted cities are in China today, air from the Victoria Harbour or above. At night, the opposite largely due to high coal use and motorisation. occurs, and surface cooling produces downslope flows along the hill and downward wall flows long the building surfaces. Cool City ventilation is, to some degree, the coupling of the urban air falls to the city street level. The slope flows and wall flows canopy flow and the atmospheric boundary layers. The wind dominate the city ventilation when the large-scale flows (or conditions around a building (length 1-10 m) is associated with mesoscale sea-land breezes) are weak, i.e. no-wind conditions. that of the neighborhood scale (length 100 m – 1 km) close Our preliminary work shows that the city ventilation rate in Hong to the building, which is associated with the whole city scale Kong due to slope and wall flows can be between 0.5 and 2 air (length 1-10 km) wind, and then the regional scale (length 50- change per hour, i.e. within an hour, there is an air flow of half 200 km) wind and finally the global-scale atmospheric flows.
