for HKUST's firstgr枷
ating class of 570 undergraduates. While they study for their final examinations and put the finishing touches to their theses, they must also keep future career prospects firmly in mind.“
According to all indicators, the career oppo前u nities for ou『 graduatesare very promising’”says Mr Brian Cheng, Student Counsellor at HKUST’
s Stu-dent Affairs Office.“
Once the recruitment season comes to an end in June we will have fuller informa-tion, but already in the Department of Accounting, 80% of its graduating students have accepted job offers from accounting firms.’,
Students from other academic disciplines have also been snapped up by the accounting profession. Economics students Rosanna Cheung. and Timothy Wong both have offers from m刮oraccounting firms, Rosanna from G『antThornton Byrne, and Timothy from Price Waterhouse.
Meanwhile finance graduate Geeta Hemrajani, who completed her studies at HKUST early, has already started work as a financial analyst in Salomon Brothers HK Ltd., a world-renowned investment firm.
“
I applied to quite a few companies, and eventually out of the three job offers that I received I chose this company because they seemed to be more enthusi”astic than the others. I liked the atmosphere here’” she says.
Not all graduates will be entering the business world. Accounting student Clement Har will be study-ing for a PhD in Accounting at the Wharton Business School of the University of Pennsylvania this autumn. He was offered scholarships to this school as well as to the Unive『sity of California at Berkeley, and the University of British Columbia. Asked for the secret of his success Clement is modest. “It's mainly help from the faculty. Without their recommendation it would not have been so easy’”he says.

l recommended him because I felt certain of his chances of success. During his time at HKUST, under the influence of our faculty, he went from strength to strength’”he says.In general terms what will HKUST
’
s graduates be doing?“Business graduates will be looking at the business sector and most engineering graduates will become enginee時, althoughsome of them might join the business sector if an oppo付unity exists there’” says Mr Cheng.“
About one-third of the science graduates will be teaching. Some will pursue re”search in major firms or te此iary institutions, and others may join the business sector in sales and marketing. Environmental protection is becoming a promising career for science students too.’,
And what is it that makes our students special?
“
Our students showed real entrepreneurial spirit by coming here’”says Prof. Lee.“Many of them gave up the chance of studying at Hong Kong’
s well estab” lished universities and took the risk of coming here. A willingness to take risks and an entrepreneurialspi 『itis what counts in today

and their families. These five colleagues a『ealso united by the challenge of doing a good job and by the enjoyment that
their work brings them. Whether it be at work, at play,。『 instudy, strong bonds have formed - the 『esult of the friendship
and warmth that they feel for each other.
MANY Hl<UST RESIDENTS might not know the name
Ping Kuen Lee. He is better known as Felix, the man to call when they need help.
“
l try to do my best to satisfy needs. My m司orobjective is to create a better living environment and to make residents as comfortable as possi-ble’”he says. This he does with the help of his crew. Yet Felix is reluctant to see himself as their supervisor.“
Estates management work requires teamwo阱,and I believe we implement this concept effectively,'’he says. “We are a great team - in fact we may be the best in EMO!”he adds laughing.
Felix, who has an Estates Management degree as well as a higher certificate in Civil Engineering, has been with the University for three years. Later this year he plans to sit for an exam and if successful, his goal of becoming a Chartered
Surveyor will be achieved. Meanwhile, when not at work, he is
kept very busy with his four-month-old daughter, Wan Yi, as well as swimming, hiking and taking tennis lessons from colleague Rick Ho.
OWNING A BIG HOUSE with a small rose garden is a long-range goal for
Rick Ho. But his sho叫- rangeone of
at-taining his Housing Management Certifi
-cate is nearly in sight - he finishes the three-year course the 『niddleof next year.
It can
’
t be easy for a newlywed of six months to put in a long day’
s work takingcare of the needs of the residents in the Phase II apa前mentsand
houses as well as Block C in the Junior Staff Quarters and then to spend four nights a week at night school. Often he doesn't get
home until ten. However, Rick enjoys his work and the company of his co-workers. "Everyone here is very nice. It's a g『eat atmosphere in which to work, and we have plenty of fun,'’he says.
Rickwo『kshard, but he certainly knows how to relax. He enjoys listening to music as well as playing (and teaching his colleagues) tennis and swimming in whatever free time he manages to find.
"I Lll<E TO TAl<E CARE OF PEOPLE,’,and that is
exactly what Eunice Au does when, like Rick, she sees to the needs of residents in the Phase II apa前mentsand houses, as well as Block C of the Junior Staff Quarters. Helping new tenants to settle in
;
overseeing cleaning;
and liaising with Security, Maintenance and the Building Services Section are just a fewexamples of how she spends her busy
day. Sometimes though, Eunice is called upon to o何eranother service that is not in
he川ob description. “When people lock
themselves o叭, the problem is soon
solved when we get the Sect』『itySection to help. However, if that person is a child, then we also have to dry some tears,'’she
smiles. Half-way through six years of pa肘,timestudy, Eunice would one day like to be a surveyor.
“
I love anything to do with people and prope叫y’” she laughs.’,DO NOT DISTURB US’,is what the residents in the
Phase I Towers and Junior Staff Quarters, Blocks A and B tell
Johnson Lei who looks after their needs.
“
We do our best to follow these instruc -tions’”he says. However, it is not alwayseasy, especially when he has to arrange
for workers to fix defects.
“
Although we have never had any trouble, and there is no cause for worry, some people don’
t want to leave their key with us.”
How doeshe get around the problem? “We persuade them with our
since『ityand patience’”he replies.
When Johnson is not at work keeping the peace, he spends
his time wo『king towards his Higher Certificate in Housing Management. When he completes this course, he would like to continue his studies. And where would he choose to do this?
“
Right here’” he says,“
at this University." And the course?“
Business and Management’”he replies.ONE OF THE PERl<S ofwo『kinghere is that you can learn
to swim. At least you can if you are as fortunate in you 『 col
leagues as Maria Lui. She was taughtto swim by Felix and Rick.

Like Johnson, Maria looks after the needs of residents in Phase I Towers as well as Junior Staff Quarters, Blocks A and 曰“I used to work in the private sector, but this is much mo『esatisfying’”
she says. “There is less of a routine, the residents are nicer and I am able to build up a good relationship with them.’,
Maria is studying for her Higher Certificate in Valuation and Housing Management, and one day she would like to become a
surveyo『.This might involve a move to England to do a degree in Housing Management.
“
Reading University is famous for this course,'’she says. "I hope that I can manage it, and should do so with the suppo付 ofmy family.”

group of postgraduate students. This year HKUST sees another
significant milestone - the graduation of its first class of un
-dergraduates. And to help these graduating students keep in
touch with their alma mater, work is already under way to
establish HKUST
’
s very own alumni association.“
Our aim in initiating this association is to maintaincommu-nication between graduates and the University and to
co-ordinate students after graduation,'’ says third司year physics
student Roger Yu Yiu Keung, who is Chai 『manof the Organising
Committee for the Alumni Association.
“
Eventually the association·will join forces with the postgraduate alumni association, which
was formed last year, and we expect to be fully established in
June or July of this year.’,
In the meantime the Organising Committee, which has
twenty-five members, is busy applying to the Government to
register the association. They are also involved in drafting a
constitution for the association, and they have regular meetings
to decide on such issues as membership structure and basic
definitions of the scope of the association.
The first activity which the association is planning for its
membe『S is a graduating dinner which will be held in June.
Graduating students will also be given a bookl訓, written by
students with some faculty contributions, as well as a souvenir
calendar showing scenes from around the campus. Eventually
they hope to produce an annual newsletter which will be posted
to all alumni who leave an address.
“
Organising all these things has taken a great deal of timeand has been a lot of hard wo『k.We have enjoyed doing it, but
for me it has been a real test of my time management skills’”says
Roger, who sits his finals this month.
And where will Roger be this time next year?“I am looking
for a post related to scientific sales and ma『keting," he says.
“
lhave sent out a few letters and am waiting for replies. I have also
applied to do a master

s degree here, and that is what I wouldideally like to do.

Steve Jacobson. He arrived here in
November 1993 f『omNorthwestern University, where he headed
a shop of the same type.
Since childhood Steve has always enjoyed making things,
whether in wo品, metal, or plastic. While in college studying
biology, he also wanted to learn to weld, and found that the
sculpture teacher was the only person on campus who could
teach this skill.
“
Next thing I knew, I was a sculpture major’”Steve says, still somewhat surprised.
“
After graduation I built asaw『nillfor a friend in Oregon, and realized that if I was going to
keep making the things I wanted to make, I had to learn
machining. I returned to Chicago, got a job in a machine shop,
some manual experience first. Without that it is hard for them to
know what to tell the machine to do. You need to have a feel for
the sequence of events when making something. It

s like bakingcakes. You can

so that the biological or pollution associated hazards probably vary depending on the source of the fish. Well-cooked fish shot』 Id not pose a health hazard associated with the biological contaminants present in localwaters. However, 'well-cooked

may translate into over-cooked. The biological contaminants can cause health problems as-sociated w.ith the digestive tract such as vomiting and diarrhoea or hepatitis.“Othe『 pollution-related problems with fish are metals, pesticides, and O『ganicsolvents. The metals are a cumulative problem which is why some health expe前srecommend NOT eating fish from polluted waters on a regular basis. Pesticides and organic solvents are also chronic type health risk problems unless the concentrations are very high in which case the fish would probably have an unpalatable taste associated with the pesticide or solvent. Although I haven

Tai Ji Quan - An Invitation
by Kimberly Chang
n
ai Ji Quan is a Chinesema付ial
art based on thephilosophy of yin and yang. Like its close ally Qi Gong, Tai
Ji aims at improving health by manipulating the body
’
Sintrinsic energy (qi) with the mind. The regular practice of
Tai Ji provides a method for integrating mind and body through a process of learning bala『iced, relaxed postures
which flow ceaselessly from one to another in a pre-ar
-ranged series. Each posture has not only a self-defense
application, but has been designed (through centuries of
refinement) to place the body in pe付ectalignment, eliminat
-ing energy blockages and encouraging the development of
balance and relaxation. If executed correctly, virtually every
Master Sin
‘
s
class practising The Wild Horse Parts its Mane.joint and muscle in the body will receive beneficial exercise.
The smooth transitions that connect one posture to another
also demonstrate the theme of change which unde『liesTai
Ji philosophy and practice.
Although beautiful to watch, Tai Ji Quan is not a
pe吋ormancea叫﹔ it is a form of physical and mental
self-cultivation for the person who is doing it. As one master
said:“Tai Ji Quan can be compared to a window with the curtains drawn. The onlooker cannot judge what is inside by
looking through the window because the cu 『tainsprevent a
clear view. Likewise, one cannot judge Tai Ji Quan by its appearance. One person may say it
’
s a form of healthfulexercise, another a martial a付, andso on. To understand Tai Ji Quan by only watching the outer movements is like
trying to look inside a room through drawn curtains. One must go into the room to see clea『ly.”
Here at HKUST, we are fortunate to have the experi
-enced instruction of Master Sin Man-Ho, a long-time
practioner and promoter of the Chinese martial arts in Hong Kong. Classes meet on Wednesday and F『idayevenings from 5:30to 6:30 p.m. in Rm. LG1027 of the Spo付SHall.We
welcome all those interested to come to the room and see
for themselves what Tai Ji is all about!
