Re: Snapshot of computing activities in Korea, 26-31 Oct 1990.
12 Dec 1990

ABSTRACT.
A brief trip to Korea to attend a Korea Information Science Society
(KISS) meeting, and to visit Pohang Institute of Science and Technology
(POSTECH), Korea Academy of Industrial Technology (KAIST), Korea
Standards Research Institute (KSRI), and Korea Institute of Science and
Technology (KIST) between 26-31 Oct 1990 is described. Some assessments
of parallel processing projects at POSTECH and KAIST are also given. 

SUMMARY.
Korea is far behind Japan and the U.S. in most computing research but
has a very pragmatic view of what they want to accomplish.  Essentially,
this is to have their own computing infrastructure even if this requires
some reinventing of known ideas and technologies. Many senior Korean
scientists have been trained or spent substantial time in the West but
have returned because of opportunities that did not exist in their own
country until recently. Thus they are keenly aware of what is going on
outside Korea. At the moment there are few Western scientists (of non
Korean origin) spending sabbatical or other research time there.
Relations between Korean and Japanese scientists are cordial, but
Koreans have a strong affinity to collaborate with U.S. and European
scientists.


BACKGROUND.

Computing activities in Korea are concentrated in three major areas.
(1) Seoul and suburbs. This includes many major and minor universities,
    government institutes, laboratories, etc. Seoul is on the Western
    coast of Korea, facing the Yellow Sea, which in turn separates Korea
    from mainland China.
(2) Pohang and Pusan. Both are on the South East coast facing Japan,
    about one hour by air from Seoul. Pohang is about 350km from Seoul.
    The water between Japan and Korea
    was called the Eastern Sea, but later renamed the Japan
    Sea after Japan occupied Korea earlier this century. Pusan is a
    large industrial port city; Pohang is the site of Pohang Steel
    Company's huge steel plant, and also of POSTECH. 
(3) Taedok Science Town. This inland town is about half way between Pohang 
    and Seoul.
    Originally this was a suburb of the adjacent city of Taejon but has now
    developed an identity of its own. Taedok has some of the same feel
    as Japanese science center Tsukuba. I was told that Taedok was set in
    its present location (south of Seoul) to be out of range of attack
    from North Korea, although this is surely not the situation anymore.
    The English spelling of both Taedok and Taejon often begins with a "D".
 


The coordinator for my visit was
     Prof. Chan Mo Park
     Professor and Chairman, Dept of Computer Science & Eng.
     Pohang Institute of Science and Technology
     P.O. Box 125
     Pohang, 790-2251 Korea
     Tel: (82= Korea) (0562) 79-2251, Fax: (0562) 79-2299
     Email: PARKCM@VISION.POSTECH.AC.KR

Professor Park also headed the Computer Science Program at the Catholic
University of America, in Washington DC, and he is currently on leave
from there. I have known Chan for many years although this was my first
trip to Korea and also my first to see him in a non Washington
environment.  He has either been a classmate, teacher, or close personal
friend of almost all the key people in Korean computing science and
technology, including the Minister of Science and Technology. Computing
is seen as a key technology for the future and computing related issues
are highly visible.  Because Korea ( = Republic of Korea = south Korea )
with a population of about 42 million, is still a technologically
emerging country, the community of scientists is relatively small, and
communication among them is very strong. Almost all the people I spoke
to knew each other, and their current projects. Senior people often come
together in Seoul for various policy meetings, perhaps several times
each month. Thus as in Japan, personal contacts  take on a highly
significant role. My own visit was far too brief to provide a realistic
analysis, hence I have titled it snapshot. I saw it as an opportunity to
learn a bit about the country, meet some people, and get a general
orientation to computing research. I expect to return in spring 1991 for
another look, in more detail.  Nevertheless, without Park's help I would
have seen far less and I am sincerely grateful for his enthusiastic
assistance.
 
For readers information, Korea gives a very different impression than
Japan. Seoul is a large modern city, as is Tokyo, but operates in a more
free wheeling way. Horns blare and cars cut in and out. If Japan
reminded my somewhat of Switzerland, then Korea reminded me of Italy.
Seoul is also much hillier than Tokyo, with a small mountain in its
center whose top can be reached by a ropeway with a spectacular view of
the city.  Prices seem to be infinitely negotiable, especially at the
open air markets where vendors hawk their products to customers. Goods
requiring stitching, from shirts to shoes to suitcases, are on display
in great profusion and at very reasonable prices. In many other ways
though, Korea looks much like Japan probably did a few years ago. The
construction, rail, road, housing, etc., infrastructure are certainly
modernizing but not yet up to the standards of Japanese or other
advanced Western countries. From the train I saw modern farms and also
some where oxen were pulling plows.  Koreans are generally larger people
than Japanese. Their language is quite different too. At international
meetings in Japan, Koreans will often communicate in English in order to
be understood.

Many of the Korean scientists I met expressed optimism that a
rapprochement would occur with North Korea (which has almost 25 million
population), although they doubted it would occur with the rapidity of
that in Germany. They also felt that Japan had some stake in this if
only that a unified Korea would be more (or less--depending on who one
spoke to) of a competitor.  There is also some strong residual feeling
about Japan generally, although it is sometimes expressed obliquely or
through humor. The Koreans are planning a high speed train to connect
Seoul and Pusan and hope to import the technology from either France or
Japan depending on who will give them a better deal--including a
significant amount of technology transfer. The people I spoke to felt
the Japanese were holding back in this area and many would be happy to
give the contract to the French, but this is all under negotiation at
high government levels. 

I sensed that Korean scientists are much more aware of nonscientific
political issues than their counterparts in Japan or the U.S. The
Minister of Science and Technology has been replaced several times in
the past few years. The Koreans discussed this frequently, as they also
did concerning government structural changes that were being proposed at
the time of my visit. Anti-government demonstrations, especially near
some universities, occur often enough that they were mentioned to me.
But my visit, during blazing fall foliage, was uneventful.


KOREAN INFORMATION SCIENCE SOCIETY.
26-27 Nov 1990: Korean Information Science Society (KISS) semi-annual
meeting. This was held at the "Korean West Point" just outside Seoul. In
addition to the usual lectures and book displays we were treated to
precision cadet marching which filled any empty time.  I had the
opportunity to meet several of the Society's officials.

       Professor Chul-Hee Lee
       Dean, Graduate School of Information Science
       Soong Sil University   
       KPO Box 1205, Seoul Korea
       Tel: 814-9611 x412
who is the exiting President and has his PhD from Purdue,
       Professor Young Chan Kim
       Dept of Computer Engineering
       Chung Ang University
       Tel: 815-5031 x 2239
who is the exiting Vice President, and was installed as the Society's
new President. 
       Mr. Hee Yol Yu
       Director General
       Technology Policy Office
       Ministry of Science and Technology
       Gwachun 427-760, Korea
       Tel: (02) 503-7656, Fax: (02) 503-7673

There were three invited lectures including my own, which surveyed
parallel processing in Japan. One was given by Chan Mo Park, emphasizing
the need for computing to reach out to all aspects of society. The
opening speech was by

       Young-Hwan Choi
       Vice Minister 
       Ministry of Science and Technology
       Republic of Korea
       Tel: 503-7604

The remainder of the first day's meeting schedule was given over to
Society business such as installing the new officials and thanking the
outgoing ones. Currently KISS has several thousand members. There are
about 100 colleges and universities in Korea, although many fewer with
significant research activities.

The second day was composed of tutorials and contributed presentations. I
attended a tutorial on Fuzzy Logic by
       Professor Kyung Whan Oh
       Dept of Computer Science
       CPO Box 1142
       Seoul 100-611 Korea
       Tel: 715-0141-7 ext384, Fax: (02) 718-4218

All the lectures except for mine were in Korean. Titles and authors of
the papers are attached below. In the Proceedings, a few of the printed
papers are in English.  There were a large number of students at this
meeting. Without being able to understand the papers in detail I sensed
that this was a good opportunity for many Korean scientists to present
progress reports of their work, although I suspect that the best work is
saved for publication in English language journals. As far as I could
tell, there were no papers in numerical computation presented at this
meeting, exclusive of those related to image processing and some aspects
of neural net computation such as character recognition. In many ways
the written Korean language is easier than Chinese or Japanese (which is
essentially Chinese), as there are far fewer symbols and they have a
form of alphabet. There is a good deal of Korean research in character
recognition, vision, and robot motion but I simply did not have enough
time to assess this in detail.

I spent some time browsing at the book exhibit and was astonished to see
a great many well known computer related books, in English, available in
paper back form, at very low prices. I received some catalogs and
discovered that the Korean publishers sell almost all U.S. texts in this
form. Many have 1990 copyrights. Later, I actually located a copy of my
book, including the disk, in a Seoul bookstore, selling for about $15
U.S. I asked a Korean colleague about this and he explained that
copyright laws are often ignored. He told me of a recent visit to his
office from a Korean book publisher's representative, who asked to
borrow (!) any new books he had received from the U.S. The quid pro quo
was that was that the professor could then select any five titles from
the publisher's catalog.  The rationalization that one often hears about
this is that Korean students could not afford to pay U.S. prices and so
it is really helping to advance science. I wonder if Western publishers
also feel so altruistic?

POHANG INSTITUTE OF SCIENCE AND TECHNOLOGY (POSTECH). 
Several Korean scientists complained to me about the level of support
for scientific research at national (federally funded) universities.
Some of the most ambitions research projects are being conducted at
private universities, and these are often established by large, well
financed corporations.  POSTECH is a premier example, established by
Pohang Iron and Steel Co in 1985, with the explicit aim of creating a
world class research university.  The brand new 350 acre campus is
located on a very much larger parcel of land owned by Pohang Steel. This
is really a mini-city, and contains housing, recreation, and school
facilities for POSTECH students and faculty as well as for Pohang's
employees.  The grounds are beautifully maintained and one gets the feeling 
of living in a park rather than near a steel mill. I didn't even see the
mill during my visit, except driving from the airport. I was told it is
one of the largest in the world. During my next visit I would like to
arrange for a tour inside.

Pohang's President realizes that steel making will taper off as a major
industry within the next ten years and hopes that some of the technology
by-products of POSTECH will be directly useful as the company
diversifies.  (Pohang is the fifth largest steel maker in the world.)
POSTECH's first freshmen class of 250 was matriculated in 1987 with
about 80 faculty. The total number of undergraduates will grow to about
1200 along with about 1000 graduates. Student faculty ratio is planned
to be less than 3 to 1, with a total faculty of about 300 by the year
1992.  The POSTECH model, mentioned to me repeatedly, is Caltech in the
U.S., and the hope is that similar quality work will be forthcoming in
several years.  Undergraduates are chosen from among the top 2% of
Korean high school students, and essentially all get four year full
tuition scholarships. Housing is free and many students get meal
stipends.  Most graduate students are research or teaching assistants,
and all (even married students) get free housing. The bottom line is
that any student who is capable enough to be accepted can study at
POSTECH without incurring any financial obligation.

Several major research facilities are in place or in the works,
including a 2 Gev synchrotron radiation source, wind tunnel,
multi-purpose pilot plant for the chemical engineering department, and a
supercomputer installation. The Computer Center Director feels he has
the support to purchase a large Convex or small Cray class machine
within the next year. At the moment the Center has a Vax 8800.

I spent two days at POSTECH. I've never seen a better endowed facility
considering that it has been open less than two years, and some
buildings are still under construction. Faculty offices are large,
bright and modern. Sun, Apollo,  and Silicon Graphics workstations are
generously sprinkled in offices, and laboratories appear as well
equipped as new universities in the West. Electronic mail is working,
mostly.  Almost without exception the faculty consists of people who
have a PhD from a Western university, or who have spent substantial time
in the West. For example, in the Sept 1987 POSTECH Faculty list (its
first), the Math and Computer Science Departments contained faculty from
Univ Michigan, Wright State Univ, Oregon State Univ, SUNY Stony Brook,
Bell Labs, Compiegne Univ, Northwestern, Univ of Maryland, and Iowa
State.  The other departments are Physics, Chemistry, Engineering and
Materials Science, Mechanical, Industrial, Electrical, and Chemical
Engineering. They have faculty from MIT, Caltech, Stanford, Deleware,
UMass, Rice, Columbia, Tulane, UTexas-Austin, UPenn, Indiana, Virginia,
Indiana, Brown, North Carolina, Berkeley, Michigan, Carnegie-Mellon,
Case, Georgia Tech, Princeton and similar excellent Western universities.
The faculty I met all speak English extremely well and typically have
some active collaboration with a Western scientist. For example, I had
an interesting conversation with

        Professor Yonghoon Kwon 
        Mathematics Department 
        POSTECH P.O. Box 125 
        Pohang 790-600 Korea
        Tel: (0562) 79-2046

who has is doing research on dynamics, chaotic attractors, etc., jointly
with colleagues in the Physics Dept at Cornell. He showed me an
extremely comprehensive and well thought out package that was running on
his SGI.  I had a few quibbles with the numerical integration techniques
that he was using, but the interface itself was as good as any I have
seen elsewhere. The Computer Science Department is also engaged in robot
motion planning.  Similarly, I had a long discussion with Professor Kun
Soo Chang, from the Chemical Engineering Department, about the software
contained in the Numerical Recipes book, and it was obvious that he was
quite familiar with the techniques that are in common use in the U.S.

On the POSTECH campus is the affiliated Research Institute of Industrial
Science and Technology (RIST). This is an independent research
laboratory that is also supported by Pohang Steel. Many POSTECH faculty
have some joint appointment at RIST; I did not have any opportunity to
visit this facility.

Faculty are treated at least as well as the students, with free housing
and for many, free automobiles. Their package is extremely generous and
accounts for the large number of qualified young professors who have
been attracted there. The Western connection is obvious in other ways
too. On the, campus Pohang has built a large log cabin and set it up as a
student faculty beer hall. I had a wonderful evening drinking beer and
eating pizza, and it was great fun to watch the Korean students eating
popcorn with chop sticks.

The Westernizing of POSTECH's faculty means that international
exchanges are expected. The school administration has already begun to
build the mechanisms for these by signing agreements with Berkeley,
Birmingham, Imperial College, Carnegie-Mellon, Compiegne, and Aachen.
This will permit student and faculty exchanges, postdoctoral
appointments, and sabbatical years. My impression is that the logistics
of a sabbatical would be very easy to arrange, given that POSTECH has
access to very comfortable Western housing.  It might be a little early,
as many of the Departments are just getting going, but interested
scientists would be advised to look into the possibilities.

There are a few minor gripes. Transportation into and out of Pohang
could be better. There are several flights each day, but the airport is
often closed because of fog. The nearest train is more than a half hour
away by car. Pohang is a small city. It is clean and safe, but it is not
Seoul.  The public school system has yet to adapt to the influx of
young, highly educated faculty. In the past the schools have been
accustomed to teaching the children of workers from the Pohang plant.
However, when the high speed rail link between Seoul and Pusan is
completed, a station will be just outside Pohang. The university has
built a large modern facility for concerts, etc., and there is a U.S.
type shopping mall near the housing complex.  Also, the schools inside
the Pohang grounds are being supported by the company; Pohang Steel
upper management, including its President, live there too.

POHANG PARALLEL PROCESSOR (POPA).
The most interesting computing research activity at POSTECH is the POPA
project, under the direction of 
            Professor Jai Yong Lee
            Department of Computer Science
            POSTECH
            P.O. Box 125, Pohang 
            Kyungbuk 790-600 Korea
            Tel: (0562) 79-2243, Fax: (0562) 79-2299
            Email: JYL@VISION.POSTECH.AC.KR
POPA refers to the POhang PArallel processor, a parallel computer based
on 64 INMOS T800 transputers. The origin of this machine is interesting.
Queen Elizabeth visited POSTECH when it first opened and gave the
university a gift of a single transputer as representative British
technology. The CS Department liked it and purchased the others to build
the system. A SUN workstation is used as a host with eight root
transputers connected to the VME bus. Each user (up to eight) is
allocated his/her own domain of processors and I/O devices through an
interconnection network. Each user can change the topology of his/her
domain. To support fast I/O, POPA has a pool of disks that are
independent of the SUN file system and these are attached to processors
via the three stage interconnection network. The latter is composed of
32x32 cross-bar switches (the mother board contains 2 cross-bar
switches). The backplane was built entirely at POSTECH.  The POPA group
has built a 16 node system and is now building the 64 node system on
eight boards.  It is possible to extend a POPA system to 256 transputers
which will have about 0.4GFLOP performance. The network manager, called
TRANSMAN and a unified software environment, called USE have been
developed at POSTECH.  For example, on the SUN, the command

   POPA -n 64 -c mesh -d 2 -g 2

will give a user a 64 processor mesh configured domain with two disks
and two graphic terminals. The POPA project has 5 graduate students, 2
researchers, and 3 faculty. They have been working for about two and a
half years and ran a workshop last summer to interest industrial
organizations in the project.  I watched as POPA ran several benchmarks,
including a traveling salesman problem, and integrating 4/(1+x*x) to get
pi. Their benchmarks indicate that the POPA system is more powerful than
early Intel Hypercubes. The idea of a multi-user, dynamically
reconfigurable hypercube is not being being pursued elsewhere to my
knowledge.

My general impression is that POPA will eventually be adapted for use by
Korean industry, to a large extent because the POSTECH faculty will be
available to consult on its use. It is also potentially helpful in
university situations as a way to give students and others experience in
parallel processing. It has already been tremendously valuable in this
way at POSTECH. The hardware is solid and reliable. As far as I could
tell the software looks in good shape as well. One indication is that
"real" documentation is available.  But POPA will never compete in
absolute performance with fast Western parallel computers. I feel that
it should be viewed as an effort on the part of the Korean scientists to
develop their own expertise rather than to obtain it from outside their
country. I saw another example of this in Seoul in the KAICUBE project
(see below).

It is much too early to tell if the POSTECH experiment will really
produce the same quality research as Caltech. Perhaps it takes decades
to emulate the infrastructure and depth of such an institution, but if
money can buy success, then POSTECH certainly has what it takes.


TAEDOK SCIENCE TOWN (KIST & KSRI). 
I had a very brief tour through the Korea Standards Research Institute
(KSRI) and the Korea Institute of Science and Technology (KIST), two
institutions located in Taedok. 

KIST.
KIST boasts the first Cray supercomputer installed in Asia (Cray 2)
installed in a building that also looks much like a Cray. Their actual
machine room is large enough to hold another dozen or so similar sized
Crays and was modeled after the installation in Minneapolis.  My overall
hosts were

        Dr. Ki Soo Sung
        President
        SERI

and 

        Dr.Park Chung Il
        Director, Computer Systems Operation Dept.
        SERI
        Korea Institute of Science and Technology
        1, Eoeun-Dong
        Taejeon 305-333 Korea
        Tel: (042) 829-1301, Fax: (042) 861-1999

KIST is already thinking about their next machine, although perhaps it
will not be a large shared memory supercomputer. I was told that
management felt that there was some advantage to buying some highly
parallel machine, if only to let their scientists learn how to use it.
Nevertheless, the KIST scientists were particularly interested in the
figures I presented based on research in large memory supercomputers
that was part of the Japanese PHI project. Later, they showed me some
finite element crash simulations that they ran in order to demonstrate
the Cray's potential to a Korean automobile company.  They claimed that
the engineers were so impressed that they quickly purchased a machine of
their own. However, the Cray is almost entirely used to run existing
application software, mostly engineering analysis packages; there is
very little software development. I was impressed with the large number
of commercial software packages that were running and was told that the
agreement KIST had with the Korean Government included a very
substantial amount for software purchase and lease on a continuing
basis. In fact, it was mentioned repeatedly that if the software money
hadn't been forthcoming KIST would not have purchased the machine. I
liked that attitude; we should also stress it in the U.S.

KSRI.
My visit to KSRI was mostly for general information purposes. It had
been arranged because the Korean's knew that I was from NIST, the former
U.S. National Bureau of Standards. KSRI is a $32 Million U.S. facility
with about 500 staff, including almost 100 PhDs. These are broken down
as follows.
	Physics		40
	Chemistry	13
	Mech Eng	12
	Elec Eng	 5
	Chem Eng	 4
	Materials	15
	Nuclear Eng	 1
	Indust Eng       2
	Management	 2
 	Computer Sci	 0
There are also over 100 staff with M.S. degrees, but only two in
Computer Science. However, a number of the scientists from other fields
are working in computing activities. For example, my host

	Dr. Jeoung Sung Cho
	Information Processing Standardization Research Lab
	Korea Standards Research Institute
	P.O. Box 3, Taedok Science Town
	Taejon, 305-606, Republic of Korea
	Tel: (042) 820-5421, Fax: (2) 231-6813
	Email: KSRI@HALLA.DACOM.CO.KR
has been working on graphics standards, and in fact knew about some
related work at NIST, in the National Computer Science Laboratory
(NCSL). Nevertheless, he felt that there was little basic research
actually going on in computing at KSRI; that almost all the work was
related to standardization activities. Nevertheless, they are heavy
computer users, and are tied in to the Cray 2 at KIST, which is only a
few minutes away.  (As with many other Korean scientists, Cho has his
PhD from an American university, in this case Iowa State.)

KSRI focuses on standards and precision measurement technologies,
particularly in physics, specifically to meet the needs of Korean
industries. Their work is funded by basic government research funds
(30%), contracts from the Ministry of Science and Technology (50%), and
contracts with various industries (20%). Projects range from a
laboratory for a Cesium atomic clock, to more practical ones such as
testing techniques to locate defects in composite materials, to the very
practical such as vibration and noise reduction in underground power
plants.

I also had an opportunity to meet 
	Dr. Hee Joon Eun
	Director, Division of Technical Support 
	Head, Office of Policy Studies
	Korea Standards Research Institute
	P.O. Box 3, Taedok Science Town
	Taejon, 305-606, Republic of Korea
	Tel: (042) 820-5030, Fax: (2) 231-6813	
In Dr. Eun's office there was a prominent display of the NIST
organization chart. Although Eun has been to the Gaithersburg lab only
once he was well aware of its new name and Director, Dr. John Lyons. He
also emphasized the role NIST played in the formation of KSRI and the
friendly relations between the organizations.

KSRI also participates in various international standards organizations
such as ISO (International Organization for Standardization), and ITU
(International Telecommunication Union), and has numerous memorandum of
cooperation with several dozen laboratories around the world. The NIST
cooperative agreement was signed in 1981. KSRI also holds an annual
workshop on the national standards system and precision measurements,
as well as a biennial metrology symposium.


KAICUBE PARALLEL PROCESSOR
My last stop was at KAIST, Korea Academy of Industrial Technology, a
major technical university in Seoul. The specific purpose of this was to
see a parallel processor called KAICUBE that I had read about in a
Japanese newspaper. Its chief developer is

	Prof Myung-Hwan Kim
	Vice President
	Korea Academy of Industrial Technology
	70-6 Yangjae-Dong
	Seocho-gu
	Seoul, Republic of Korea
	Tel: 575-3955, Fax: 577-5488.
Unfortunately Professor Kim was not in his laboratory when I arrived,
but several other faculty and graduate students showed the system to me.

KAICUBE is more or less a standard hypercube. KAICUBE I uses a 68020 CPU
and 68882 floating point unit. Maximum communication speed is 120M bps.
At this time a 64 node KAICUBE II has been built, with peak performance
of about 64MFLOPS. The first machine, with 8 nodes was completed last
year.  The group has just begun to build a 128 node machine (KAICUBE
III) with the new, faster Intel i860 processor. They estimate that it
will be completed at the end of 1992 and will have 5GFLOP peak
performance. It will also have improved communication, up to 320M bps.

The KAICUBE group briefly showed me some of their work on the
architecture and software development of the machine, which they have
done essentially all themselves. As far as I can tell there are no
documents available in English. The little documentation I did see
described various applications, such as solving Laplace's equation,
sorting, FFT, Simulated Annealing, and database query acceleration. But
I had no opportunity to discuss this with any of the actual users. I was
shown the results of one benchmark (travelling salesman problem) in
which the KAICUBE II was 2.5 times slower than the Cray 2S.
Nevertheless, as this is in almost every way a traditional hypercube, I
asked them specifically why build it when they could buy one much more
easily. Their answers were frank and illuminating. Basically they want
to learn how to do it themselves so that don't have to buy the
technology from outside.  As far as I can tell this is much the same
motivation that drives the POSTECH project.  This is an excellent way to
train students and develop basic research technology. Its most important
use is internal, but the Japanese have shown that this approach can be
successful at rapidly catching up with research in more advanced
countries. What is not clear though, is whether, once rough parity has
been achieved, if breakthrough ideas will also be forthcoming.


KOREA SCIENCE COUNSELLOR.
I also stopped in for a courtesy visit with 
	Mr. Kenneth Dewitt Cohen
	Counselor for Scientific and Technological Affairs
	U.S. Embassy

yk4@cunixb.cc.columbia.edu (Yong Su Kim) (12/13/90)

The Kahaner Report was extremely informative.  It certainly answered
a lot of questions I had about Computer activities in Korea.

Are there other such reports done by other authors?

Kahane seemed to be convinced that Korea was not anywhere near the
level of other advanced nations such as the United States and Japan.
