Background: The purpose of this study was to investigate longitudinal changes of the utilization of operational and surgical medical care inside and outside a metropolitan area over 10 years, analyzing the residential areas of patients and the locations of medical facilities for major cardiovascular surgery. Methods: Data analysis was conducted by classifying the addresses of patients and the locations of medical care facilities of metropolitan cities and provinces, using data from the National Health Insurance Corporation from January 2003 to December 2013. Results: There is serious concentration of major heart surgery to medical facilities in Seoul; this problem has not improved over time. There were differences in percentages of surgical procedures performed in the metropolitan areas according to major diseases. In the case of Busan and Daegu provinces, at least 50% of the patients underwent surgery in medical facilities in the city, but there are other regions where the percentage is less than 50%. In the case of provinces, the percentage of surgical procedures performed in medical facilities in Seoul or nearby metropolitan cities is very high. Conclusion: Policies to strengthen the regional capabilities of heart surgery and to secure human resources are required to mitigate the concentration of patients in the capital area. Many regional multi-centers must be designated to minimize unnecessary competition among regional university hospitals and activate a win-win partnership model for medical services.

( Sook Kyung Lee ),( Taek Geun Lee ),( Hyun Hwang Bo ),( Tae Gwang Kwon ),( Se Won Jung ),( Young Seok Lee ) 대한피부과학회 2013 대한피부과학회 학술발표대회집 Vol.65 No.2

Background: Complementary and alternative medicine (CAM) is any practice that has healing effects, but is not based on evidence demonstrated by scientific method. Recently, CAM has been used in various diseases including acne. However, there have been no studies on CAM for acne in Korea. Objectives: The purpose of this study was to analyze the use of CAM in acne patients. Methods: A total of 159 patients with acne were enrolled on the study, and filled out a questionnaire about use of CAM. Results: Overall 87.4% (139/159) of the patients reported the previous or current use of at least one more type of CAM. Cosmetics for acne (100, 22.9%) was most frequently used, followed by diet therapy (81, 18.5%), spa and bath therapies (77, 17.6%), health food supplement (67, 15.3%), skin care shop (64, 14.6%), oriental medicine (38, 8.7%), and aromatherapy (9, 2.1%). The most common reason for using CAM was ``wish to try everything`` (28.6%), and the most common source of information was internet (40.5%). The therapeutic effect of CAM was best with diet therapy (32.1%). The most common side effect of CAM was aggravation of symptoms. The most common monthly cost for CAM was between 50,000 and 100,000 won/person. Conclusion: As our results, we can predict that the use of various types of CAM for acne will become more common. Therefore, dermatologists need to study about benefits and adverse effects of CAM for acne.

Idiopathic hypereosinophilic syndrome is characterized by marked elevation of eosinophil count ( >1,500/㎣) in peripheral blood without explaining etiology. It shows tissue involvement in many organs such as liver, G-I tract, myocar dium, lung, skin, kidney and nerve. Some case of hypereosinophilic syndrome with hepatic involvement have been reported, but not much. We have recently experienced a case with idiopathic hypereosinophilic syndrome of a 40 year old man who presented with RUQ pain. By abdominal CT, ill- defined subcapsular hematoma was detected. Liver biopsy showed eosinophilic infiltration within the portal tract and sinusoid. Drain procedure and corticosteroid adminiiatbrought marked improvement of clinical manifestation, hematologic abnormality and radiologic abnormality.

본 연구는 ProFile, ProTaper및 K-Flexofile로 근관 성형시 근관의 만곡도에 따라 근관의 형태가 어떻게 변화하는 지를 비교 분석하고자 시행되었다. ISO #15 Hnger spreader를 15도, 30도 및 45도로 만곡시키고 에폭시 레진으로 각각도의 근관을 갖는 30개의 근관 모형을 제작하였다. 근관의 길이는 18 mm로 하였고 근관의 만곡은 근관의 입구로부터 10 mm부위에서 시작하도록 제작하였다. 근관 성형에는 엔진 구동형 니켈-타이타늄 파일인 ProFile과 ProTaper, 수동형 stainless steel 파일인 K-Flexonle을 사용하였다. ProFile과 ProTaper는 제조자의 지시에 따라 크라운다운법으로 근관 성형하였고, K-Flexofile은 스텝백법으로 근관 성형하였다. 근첨부 성형은 #25 파일 크기까지 시행하였다. 근관성형 전·후 이미지를 스캐너를 이용하여 얻고 Photoshop 7.0 프로그램을 이용하여 중첩하였다. 이미지 분석 프로그램을 이용하여 치근단 쪽에서부터 1, 2, 3,4, 5, 6, 7,8, 9 및 10 mm부위의 내·외측 폭경 변화와 총폭경 및 근관의 중심축에 대한 근관 변위을 측정하였다. 각 부위에서 내·외측 폭경과 총폭경 및 근관 변위의 유의성 검정을 위해 one-way ANOVA 분석을 시행하였으며 각 기구간의 유의성 검정은 Scheffe's test로 사후 분석하였다. 또한 기구의 변형과 파절 여부를 평가한 결과 엔진 구동형 니켈-타이타늄 파일인 ProFile과 ProTaper를 사용하여 근관성형시 수동형 스테인레스 스틸 파일인 K-Flexofile에 비해 근관의 변위를 적게 유발하고 특히 ProFile이 근관 성형시 바람직한 기구임을 시사하였다. The purpose of this study was to evaluate the canal configuration after shaping by ProFile, ProTaper and K-Flexofile in simulated resin canals with different angles of curvature. Three types of instruments were used : ProFile, ProTaper, K-Flexofile. Simulated root canals, which were made of epoxy resin, were prepared by ProFile, ProTaper with rotary instrument using a crown-down pressureless technique, and hand instrumentation was performed by K-Flexofile using a step-back technique. All simulated canals were prepared up to size 25 file at end-point of preparation. Pre and post instrumentation images were recorded with Scanner. Assessment of canal shape was completed with Image Analysis program. Measurements were made at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 mm from the apex. At each level, outer canal width, inner canal width, total canal width, and amount of transportation from original axis were recorded. Instrument deformation and fracture were recorded. Data were analyzed by means of one-way ANOVA analysis of variance and the Sheffe' s test. The result was that ProFile and ProTaper maintain original canal shape regardless of the increase of angle of curvature than K-Flexofile. ProFile show significantly less canal transportation and maintained original canal shape better than ProTaper. [J Kor Acad Cons Dent 30(4):294-302,2005]

This study was carried out to recognize the distinctive quality of the scene around 'PUNGAMGEONG'(楓巖亭) through appreciation in its building, location and architectural view of the space based on 'KIM CHUNG JANGGONGYUSA'(金忠壯公遺事), published during the reign of 'JEONGCHO'(正祖) in 'CHOSON'(朝鮮) dynasty. The study was conducted by contents analysis of 'KIMCHUNGJANGGONGYUSA' and other related paleography as prime as well as verification of the location and architectural view of the space through field survey with topographical chart(1/5,000, 1/25,000) and survey drawing. Analysis method fell into the background of building and location space structure as well as a comparative analysis of the literature with interview with local authority staffs and descendants. The results are as followings; 1) The background of the Pungamjeong's building is influenced by KIMDEOKBO(金德普)'s amusement(good landscape gusto) in fine view and moralistic view in nature as well as seclusion and recuperation with misfortune of his family. 2) Location of the Pungamjeong is suitable for seclusion with graceful natural scenes as well as adjacency with the ancestral burial ground for memorial service. 3) The space structure of the Pungamjeong for literature analysis consists of the space for production in bamboo grove to stream surrounding, the space for study and appreciation in pavilion and the space of fairyland in left side of locks. 4) The Pungamjeong stands with a pavilion of two rooms reconstructed in the tile house, and the vegetation appears in the literature of Pinus dansiflora S. et Z, Prunus mume S. et Z, Phyllostachys nigra Munro, Acer pseudosieboldianum Komar and Prunus persica (L.) Batsch forming identifying marks, but Pinus densiflora S. et Z, Phyllostachys nigra Munro, Abies holophylla Maxim, Acer pseudosieboldianum Komar, Carpinus laxiflora Blume, Zelkova serrata Makino, Prunus sargentii Rehder, Fraxinus rhynchophylla Hance, Quercus monglica Fisch and Rhododendron mucronulatu Turcz are found recently. Also, wild natural rocks in the Pungamjeong are one of its valuable parts representing personality of folk belief to the local residents. It is recommended that further embodied and substantive studies should be followed with the systematic literature analysis and field survey for restoration and maintenance of the place since this study comes from the literature analysis only.

연극활동을 통한 수학지도에 관한 연구

The mathematic power focused on the seventh curriculum is an ability of solving problems and the ability is hard to just by applying memorizing and applying of formulas. If fruits are produced in haste, the trunk and the root grow to be weak naturally. The mathematical power is the ability of solving the problems and the power comes form the strong root of mathematics. The trunk form the strong root makes dense branches in some time and fruits as a result of it are the ability of solving problems. At first, mathematics was an interesting subject to the children contacted with. They had interests in numbers and counting. They could practice at home and were pleased with receiving pocket money after solving the problems from uncle. However, the familiarity didn't last long. They couldn't practice at home and uncle didn't give problem to them because mathematics become difficult. They wonder most if it is necessary that they should learn mathematics even though they are good at addition and multiplication. That's because they can't find any interest in math in daily lives. The familiarity from the beginning to the higher grade, mathematics is hard like a natural course. The teachers sympathize with the idea that to make students understand mathematics, an abstract subject, is too hard only by simple instruction using blackboards. Update materials for mathematic instruction is encouraged to use and is actually utilized in many schools. Rapid development of computer changed the contents and method of mathematical instruction and it is necessarily so. Instruction with computers and update materials only gives a stimulus to the sense of sight and sense of hearing in the displaying teaching method like instruction with blackboard demonstration. That's how I introduce drama to the mathematic instruction. It is composed not by displayed teaching but by acting drama as a way of instruction. Change should not necessarily result in development, but there is no development without change. More concerns and study are in need because it is a new attempt as a way of mathematic instruction.

This study was carried out to recognize awareness of the scholars in Chosun Dynasty on the pavilion management through the philological literature study of Young-Sa (用事:A Chinese poem, Allusion). The 18 pavilions were selected as subjects with following selection criteria. - Being extant of poetry and prose in the pavilion among 100 pavilion candidates, quoted from Nujungjeyoung (Published by Gwangju-City in 1992). - Built in Chosun Dynasty. Focusing on contents analysis, the words that are categorized in allusion were abstracted and then comparative analysis for meaning of the word and frequency of appearance with source were carried out. The findings are as follows ; 1) It is of loyalty and filial piety phenomenon. A man of high frequency in pavilion allusion is the person who has contributed to loyalty and filial piety. It is believed that moral of loyalty and filial piety were provided through referring to the Chinese ancient history. One of examples is that naming pavilion meaning of place for composing poem of pledging loyalty to the king cherishes the memory of late fathers. 2) It is building temperament/character. Expressed an attitude of building temperament/character in pavilion through alluded men and ancient history. Mainly JUJA, Confucius and MANGJA were alluded. The expression of willingness in building temperament/character is reflected in poems by allusion of delegated men. 3) It is ethics and seclusion phenomenon. The origin of the ethics phenomenon in Chosun dynasty orginated from the outside, but its formation and progress were influenced by the Honam district (the southwestern part of Korea). The foundation of such progress was pavilions and pavilion literature, surrounding Lake Gwangju. 4) Seeking for hypothetical scene. Alluded Chinese famous names of places were familiar with oral tradition or reading and assumed to be hypothetical scenes of pavilion builders. The meaning of alluded scenes materialized hypothetical scenes in the individual mental image that is learnt from ancient times. That is, the aspiration of the builders for Utopia is reflected into hypothetical scenes. This study analyzes immanent meaning of the words, expressed by allusion in poetry based on sources. Lack of structural and semantic study of Chinese poems is the limit of the landscape architectural approach and a supplement theoretical study of Chinese poems is needed.
