Pukyong National University is a national university located in Busan, South Korea. The 2nd largest city of Korea, which is the location of Busan Port, Gwangan Grand Bridge, Haeundae Beach, Oruk Islet, and Jagalchi. The university has two campuses - Daeyeon-dong and Yongdang-dong. These campuses are situated near coastal district of Nam-gu. The location itself suggests that Pukyong University has a strong traditional focus on fisheries science and other maritime fields. The University has excellent facilities for Marine and Technology studies.The University has been taking the lead in the marine products industry since the initiation of deep-sea fisheries in Korea, on the basis of scientific achievements in the study of oceanography with the object of making the best use of present marine resources while maintaining a rich repository of natural resources for the future. Pukyong National University has one of the highest graduate employment rates among national universities in Korea. Furthermore, Pukyong has cultivated 170,000 top-notch graduates who currently make invaluable contributions to national industries and to the prosperity of the world.Recently the University has established new departments of international affairs and information engineering. Faculty members have published numerous intellectual research papers in academic journals to meet the needs of national and regional developments in present-day Korean society.Pukyong National University is an active and creative national university which was formed in 1996 from the merger of two national universities with long histories, the National Fisheries University of Busan which was established in 1941 and the Busan National University of Technology which was established in 1924. It serves as an exemplary university, standing as a model institution for other national university to emulate with regards to educational and research achievements in KoreanHistorically, the Daeyeon-dong area was a small fishing village which was populated by anchovy fishermen. In the early years of the 20th century these fishermen found their products in high demand and amassed a fairly sizable amount of wealth. With this money they purchased what is now the Daeyeon-dong campus land and donated it to the national government under the condition that it be used to establish training for their industry. During the Korean War, the Daeyeon campus was used as an airfield by the U.S. Air Force. Local residents constructed a large Dol-Jip “stone house” for the commanding officers and pilots. Today this building still stands and is used as a student cafeteria.At present, there are some 26,000 students and 544 professors on both campuses which cover 673,899 m2. Three large libraries are there. The old library is open to students 24 hours a day. A network of shuttle buses runs every 15 minutes. The two campuses are separated by about 4 km distance. The bus takes 10–15 minutes and is free for students.Although primarily a fisheries university, PKNU has 6 colleges including a large humanities and social science department, 4 graduate programs with master's courses in 60 departments in 15 interdisciplinary programs and doctoral courses in 56 departments and 12 interdisciplinary programs. In addition there are 8 research institutes. Wikipedia.


An optical fiber flexible multi-wavelength filter based on a polarization-diversity loop includes a pair of high-birefringence optical fibers, a polarization beam splitter connected to the pair of high-birefringence optical fibers and dividing light incident from a broadband light source into two polarized beams, and a polarization controller connected to the high-birefringence optical fibers or the polarization beam splitter and controlling the two polarized beams divided by the polarization beam splitter. The polarization controller includes a wave plate or a wave plate, and the polarization controller disposed between the high-birefringence optical fibers controls an angle difference between principal axes of the high-birefringence optical fibers and visibility. Interference in the high-birefringence optical fibers is controlled via changing polarized light incident from the broadband light source using the polarization controller.

Disclosed is an ice floater for facilitating ice freezing on the water surface. More specifically, disclosed is an ice floater for facilitating ice freezing on the water surface made of a naturally degradable resin that prevents mixing and convection of seawater cooled on the surface with not-cooled water, when floating on the water surface and thereby facilitates formation of ice on the seawater surface. Once ice sheets are formed, fallen snow particles and water particles broken by waves are accumulated as ice on the water surface and thus naturally continue to growth.


The electrode structure for measuring a bio-signal and an apparatus for measuring an electrocardiogram using the same are disclosed. The electrode structure for measuring a bio-signal, comprises an electrode pad to measure bio-signals based on capacitive coupling between the electrode pad and human skin; an absorption layer formed at one side of the electrode pad; and a preamplifier which is electrically connected with the electrode pad and filters noise from the bio-signals from the electrode pad and amplifies and outputs the signals. Thus, the initial noise stabilization time can be reduced, and stable electrocardiogram signals can be obtained quickly without noises.
