Chung (PhD, 1971; Distinguished Alumnus, 2002), together with his wife, Young Sook treated his former PhD advisor, John Berg, to a week-long grand tour of Korea this October. Sites visited included highlights in and around Seoul: the Seoul Tower (highest point in the city) and ancient ramparts, the South Gate, the Presidential Blue House, Insadong Street (the arts and crafts district), Cheonggyecheon Stream (a linear park running some four miles through the city), a look into the DMZ, and traditional dinner and entertainment at the Korea House, an early 15th century minister's residence of the Joseon Dynasty, the last monarch, 1392-1910. They also took the bullet train to Gyeongju, a national park and archeological site near the center of the country and the ancient capital of the Shilla Dynasty, 57 BC - 932 AD. Ancient burial sites, museums and a series of thousand-year-old Buddhist temples were visited. Gyeongju was also host to a World Culture Expo at the time, which they attended. The trip included a two-day visit to the lush resort island of Jeju, where they hiked among dormant volcanic craters, in a dense subtropical forest and along beaches. They visited the world-famous cliffs of basaltic stone columns, a magnificent Buddhist temple, and many other sights. The tour concluded with a moving visit to the site of the pivotal Incheon landing during the Korean War, with its Memorial Hall and Museum, and the adjacent Freedom Park, celebrating Korean-American friendship. "It was a wonderful experience: beyond my dreams," says Prof. Berg. Dr. Chung was one of Dr. Berg's first PhD students. He went on to become a leading industrialist in Korea, a faculty member of the Korea Advanced Institute of Science, and a Full Member of the National Academy of Engineering in Korea. He is presently Professor of Chemical Engineering at Inha University and is a member of the BOD of the S-Oil Corporation on the 2007 Fortune Global Top 500. He served for nine years as the President of the UW Korean Alumni Association, and more recently co-spearheaded an effort to raise $3M to rescue the Korea Studies Program at the University of Washington.

• HEWLETT-PACKARD SPONSERS NEW RESEARCH The Hewlett-Packard Company is sponsoring new research in our group dealing with Ink Jet Printing. This will involve the work of one new graduate student beginning in November, 1999, and a second graduate student beginning in summer, 2000.

• SUSIE STENKAMP COMPLETES PHD DEGREE Susie Stenkamp completed and defended her PhD disertation, entitled: "Steric and Electrosteric Stabilization of Colloids in Aqueous Slat Solutions" in October, 1999. She has taken a research position with Battelle Pacific Northwest National Laboratories (PNNL) in Richland, WA.

• PROF. BERG SERVES AS EXTERNAL EXAMINER Prof. Berg served as External Examiner for the Ph.D. Dissertation of Bjorn Johansson at the Royal Institute of Technology in Stockholm, Sweden, in October, 1999. The thesis title was "Surface Chemistry of Flotation Deinking," and was supervised by Prof. Goran Strom. The External Examiner is titled the "Opponent" in Sweden, but the experience was very rewarding and cordial. It was also a chance to catch up with old friends in Sweden.

• INDUSTRIAL SHORT COURSE. The 13th annual offering of the Short Course on Surface and Colloid Science was given this year: July 12-16, 1999, and had a total of 43 participants. The course, which is also planned for 2000 (July 10-14, 2000; check this site for further details) consists of lectures in the morning covering the basics of colloid and interface science, and laboratory demonstrations in the afternoons, illustrating up-to-date laboratory techniques for property measurement and system characterization. The course is designed for industrial researchers, engineers and technicians dealing with surfactants, thin films, coatings, natural and synthetic fibers, adhesives, lubricants, wetting agents, foams, pigments, powders, aerosols and other materials for which surface properties play an important role. The course fee for 2000 is $1375, and university housing is available for modest rates. Interested persons should contact Engineering Professional Programs; University of Washington; Box 358851; 10303 Meridian Ave. N.; Suite 301; Seattle, WA 98133. FAX: (206) 543-2352

• LILY WOO COMPLETES MS DEGREE Lily Woo completed and defended her MS thesis, entitled: "Adsorption of Polyelectrolytes on Colloidal Particles" in June, 1999. She has taken a research position with Praxair Surface Technologies in Indianapolis, IN.

• UNDERGRADUATE WINS AWARD AT NORTHWEST REGIONAL CONFERENCE One of Dr. Berg's undergraduate research students took the Third Place prize for his research presentation at the Pacific Northwest Regional Student Paper Contest Apr. 30-May 1, 1999, hosted this year by the Oregon State University. KERRY PERSON WON $300 in the Paper Competition for his paper entitled: "Measurement of Surface Tension in the Millisecond Range."

• INVITED PAPER AT MRS MEETING Prof. Berg presented an invited paper at the Materials Research Society Spring Meeting in San Francisco, Apr. 5-9, 1999. It was entitled: "The Acid-Base Energetics of Adhesion in Composite Materials."

• MILLER SPENDS WINTER QUARTER IN ULM, GERMANY Alan Miller spent the Winter Quarter, 1999, working with the Experimental Physics Group at the Tech. University in Ulm. He worked specifically on the acoustic analysis of adhesive failure in filled polymer composites (with Dr. S. Minko) and on Pulsed-Force Mode Atomic Force Microscopy (with Prof. Dr. O. Marti).

• DICKSON COMPLETES MS DEGREE Lynne Dickson defended her MS thesis in January, 1999.

• PAPER AT EUROPEAN ADHESION SOCIETY AND LECTURE AT TU ULM Prof. Berg presented a poster or the group's recent adhesion work at EURADH '98 - the 4th European Conference on Adhesion, in Garmisch-Partenkirken, Sept. 6-11, 1998. The following week he presented a lecture to the Experimental Physics Group at the Technical University of Ulm, Germany.

• PROF. BERG GIVES INVITED LECTURE AT GORDON CONFEENCE ON ADHESION Professor Berg gave an invited lecture entitled: "The Importance of Acid-Base Effects in Adhesion Control using Amphiphilic Agents," at the invitiation of conference organizer, Dr. Alphonsus Pocius. The conference was held at Tilton, NH, the first week of August, 1998.
