  • Dr. George Schimert, born in 1918 in Switzerland, received his medical degrees from universities in Hungary and in Germany. After immigration to the United States, he continued medical training at several hospitals. In 1956, for pursuit of cardiac surgery, he had joined the group headed by Dr. Walt Lillehei at the University of Minnesota. During this period, in 1958, he joined Seoul National University Hospital as a overall medical adviser and adviser in surgery for 15 months in partnership with the University of Minnesota Medical School. During his stay in Korea, in addition to the works in the medical administration and education, he contributed to the early establishment of thoracic surgery program. In August 6, 1959, he performed open heart surgery using cardiopulmonary bypass for an ASD patient at Seoul National University Hospital. However, the patient died 6 hours after the operation. In 1960, after returning to the United States, he began his career at Buffalo General Hospital as the first director of its cardiac surgery program. In 1985, the Dr. George Schimert Lectureship and Medical Conference was established to honor his contributions and achievements. He died December 7, 2002.

  • Total phosphorus(TP) removal was examined in a surface-flow wetland constructed in April 2003 during its initial operating stage from June to November 2003. Its dimensions were 87mL by 14mW. It was a part of a four-wetland-cell treatment system constructed near the Kohung Estuarine Lake located in the southern part of Korea. Effluent from a night soil treatment plant was discharged into the wetland and purified effluent from the wetland was discharged into Sinyang Stream flowing into the Lake. Cattails(Typha angustifolia ) from natural wetlands were cut at about 40 cm height and transplanted into the wetland. An average of 25.0$m^3$/day of effluent flowed from the plant into the wetland. Water depth was maintained about 0.2m and hydraulic detention time was about 5.2 days. Average heights of the cattail stems in June and October 2003 were 47.2 and 164.6cm, respectively. The average number of stems was 10.2 stems/$m^2$ in June 2003 and 18.8 stems/$m^2$ in October 2003. Average temperature of influent and effluent ranged 23.4 and $24.2^{\circ}C$, respectively. The average TP concentrations of influent and effluent were about 1.31, 0.50mg/L, respectively. TP loading rate of influent into the wetland averaged 26.81mg/$m^2$, day and average TP loading rate of effluent was 10.04mg/$m^2$, day. Monthly average TP removal by the wetland during the warm growing season of cattails(June to September) ranged 16.28~19.57mg/$m^2$, day and during the cold senescent period (October to November) ranged 12.62~13.90mg/$m^2$, day. TP removal in the wetland continued during the cold winter months and was primarily done by sedimentation and precipitation of phosphorus rather than phosphorus absorption by cattails and microorganisms.

  • Aplastic anemia is a disease characterized by general lack of bone marrow activity; It may affect not only the red blood cells but also the white blood cells and platelets, resulting in pancytopenia. Spontaneous gingival hemorrhage is present in some cases and it is related to the blood platelet deficiency. This case report presents the periodontal treatment of a patient with aplastic anemia. A 43-year-old female was referred for continuous gingival bleeding after periodontal treatment. Periodontal findings revealed generalized gingival imflammation, oozing of blood from gingival crevice, and it was diagnosed as adult periodontitis. Root planing and extraction of the upper left third molar with poor prognosis were put into operation after elevation of the platelet count with platelet transfusion. The extraction socket was sutured with 3-0 silk. Bleeding continued even after digital compression at the upper right second premolar, second molar, and left canine areas, which presented severe inflammation. Although platelets were transfused repeatedly, platelet count did not stay elevated since survival rate of the transfused platelets were low due to alloimmunization. Thrombin gauze packing was not effective. Bleeding ceased 3 days after treatment with transfusion of donor platelets. 20 days after the treatment, the gingiva was generally healthy except upper right second premolar and lateral incisor areas. The result of periodontal treatment was good, but bleeding control after treatment was troublesome. In the periodontal treatment of patient with aplastic anemia, elevation of the platelet count with platelet transfusion seems to be the best method for hemorrhage control.

  • Since 1985, the Ministry of Environment has supported environmental education in schools through Environment Conservation Model School initiative. Selected elementary, middle, high schools and kindergartens were designated as model schools for environment conservation programs every 2 years to develop model cases that can be adopted at other schools to promote more structured and effective environmental education. These supporting programs played a central role in developing an environmental education model for formal schools and enhance the importance of environmental education in school curriculum. This study aims to evaluate the current statues of environment conservation model schools and support to environment conservation model school initiatives which have created basic framework to enable the continued development of environmental education. For the study, documents and reports from 1985 to 2005 were analyzed, which included operation guidelines for model schools, case studies, implementation reports along with the systematic analysis of documentations. Also this study included interviews and a survey with people responsible for running programs, and consultation processes with experts to address the current status and issues related to Environment Conservation Model School initiative. Based on the present status and issues, the recommendations for improving Environment Conservation Model School initiative were provided.

  • In line with post-1970s industrialization, the manpower shortage in fishing villages has been fueled by rapid desertion; young adults and middle-aged people have tended to avoid fishing by migrating to cities, driving the emergence of a national issue in terms of securing fisheries management succession. For the fisheries industry to maintain competitiveness, we need to cultivate young adults and middle-aged people to be leaders of the domestic fishing industry through promoting inspiration for the fishing industry, teaching fisheries expert knowledge, and fostering the ability to promote business. In addition to safe supply of marine products through continued fisheries operation, securing young and skilful workers is essential in order to promote balance development of domestic industries, including job creation. The study therefore seeks to provide measures to foster specialists in order to enable the transfer of management through an opinion survey of fishermen. To cultivate specialists for enabling the transfer of management, the following solution should be promoted at the state level. First, to support the introduction of young and talented workers to the fisheries industry through transfer of management, Second, in order to enable the transfer of management, change is required first in the fisheries industry for it to become a value-added industry. Third, despite fisheries being a composite industry that is syncretized to tertiary industries from primary industries, the fisheries industry is still recognized as a labor intensive industry, which reflects the current status of fisheries education.

  • This study was performed to evaluate the possibility of inducing analgesia by electroacupuncture stimulation at single acupoint or combined acupoints and to examine the analgesic effects following the combination of premedication and electroacupunrture analgesia(EA). Analgesia was induced by EA with the current of 1-4 volts and the frequency of 10-45 Hz to the acupoints Uown to be related to analgesia on the head/necIL axial part thoracic and pelvic limb. In Yi Feng acupoint of head/neck part pain responses were not disappeared after electroacupunrture stimulation to the head/necIL thoracic limbo thoraxl abdomen, loin, rear and pelvic limb. Pain responses were remained after EA of Tian Men-Tian Ping and Shen Yu arupoints of axial park whereas hypoalgesia was observed after EA of Tian Ping-Bai Hui acupoint in all parts of body. There was no analgesic effects after EA stimulation of the brachial plexus and Wai Kuan acupoint, whereas after EA stimulation of San Yang Lo, pain responses were disappeared in headfnecll, thoracic limb and pelvic limbo and in the other parts of body hypoalgesia was shown. In EA stimulation of Tsu San Li acupoint pain responses were disappeared in pelvic limb and in San Yin Chiao acupoint pain responses were disappeared in head/necIL thoracic and pelvic limb, and hypoalgesia was shown in abdomen. On the combination of San Yang Lo Pli Men) and San Yin Chiao (Pu Yan6 acupoints, pain response in heauneck was decreased in 5 minutes, whereas analgesia in thoracic and pelvic limb was induced after 20-30 minutes and in abdomen was noted after 50 minutes. The more frequrncy was increased, the more rapid analgesic e11%t was induced. The analgesic effects wert not good in laparotomy under EA at the combination of San Yang Lo (Xi Men) and San Yin Chiao (Pu Yang) arufoints. Enteroanastomosis could not be continued under acrpromazine, xylazine and diazepam with EA. However, under EA followed by tiletaminetzolazepam, the operation could be completed without additional anesthesia and the analgesic effects were good. There were no changes in clinical signs, hematological and serological values after combination of the premeditation of tiletamine+zolaEepam and EA. It is considered that EA alone is not suitable for the main surgery, but the combination method of EA and sedatives can be utilized in practice.

  • This work was performed to find the effect of operation parameters on the permeate flux through the activated sludge dynamic layer, and to indicate the relationship between the water quality of supernatant and flux based on the results. Since the effluent can be obtained through steady and stable formation of cake layer in the bio-filter media system, it is an important subject to keep and control microbes with activated state in the bio-reactor. Filtration resistance was drastically increased at more than 18000mg/L of MLSS. With filtration time continued, the flux was gradually decreased and the water qualities of supernatant monitored by turbidity and TOC were also deteriorated. This phenomenon indicated that the organic materials generated by microbes and accumulated in the reactor might affect the flux in the system. In addition, the decrease of flux was simultaneously observed in the sludge volume index. When SVI was controlled from 150 to 250, the flux was also decreased. The proper aeration time was recommended to 30 to 60 seconds in this system. In order to operate this system steadily, therefore, the control of water quality of supernatant and SVI should be proceeded.

  • Since the early 20th century photo based art and effort to creative experiment, to pursue the essence of creation to escape from stereotypes between form and media, expression and technology, has been continued persistently. Photomontage was born as an artistic attempt for the new representation. Basically photomontage is configured to visually emphasize the message as a work to produce new meaning by combining the various images that are intentionally selected. The photomontage as a visual art, dialectic of text and image that is to pursue a new format to be out the concept already existing, have been developed, the concept is similar to the modern multiple art. The value of photo montage is to explore of the photo, not limited to describe or reproduce as a deformation, the new possibilities for creative expression and the experience of the day-to-day operation for the implementation of the scheme.

  • Looking at Korea's manufacturing industry, there are many old manufacturing plants. In fact, the manufacturing process of the product inventory management and the unit price of the product are all created by using Excel, and the factory is operated by using it. Also, the operator can not predict the failure of the equipment in order to produce the product at work. Problems related to this may result in the loss of the documents during the instruction and work process between the manager and the worker, and the communication between the manager and the worker can not be properly performed, There is appear a situation in which the operation is continued by using the equipment without recognizing in the failure. In this paper, we propose a method for upgrading the aging manufacturing plant to improve the productivity and productivity of the product by predicting the efficient inventory management, unit price management, production volume, and the operator's failure prediction.
