Background: In the patients with thoracic injury, we suspect simultaneous cardiac contusion or concussion. We analyzed the patients with possible cardiac injury by electrocardiography, serum creatine kinase (CK), creatine kinase isoenzyme fraction (CK-MB) screening, followed by two dimentional echocardiogram (2-DE) to access the severity of injury. Material and Method: From January 1997 to April 1998, 15-month retrospective study of suspicious myocardial injury was undertaken in including 24 patients admitted for suspected cardiac injury. All patients with history or signs of blunt chest injury were checked serially and the serial CK, CK-MB fraction, electrocardiography (EKG) analysis screening were followed by 2-DE. Result: The age range was between 20-40 years and were predominant male patients in(M:F=3:1). Most common causes of injury were traffic accidents, 15 patients(62.5%). Associated injuries involved multiple rib fractures, sternal fracture and such. EKG findings on the cardiac concussion were within normal limits, EKG findings on the cardiac contusion were nonspecific ST and T wave abnormality. In cardiac contusion patients, CK-MB fraction did not increase significantly on admission but on 2nd, 3rd, 4th hospital days, it increased significantly (p=0.0080, 0.0130, 0.0130). The average admission days were 9.22 in concussion and 26.18 in contusion patients(p=0.0075). Most common complication was the adult respiratory distress syndrome(7 cases), 5 out of the patients with ARDS were mechanically ventilated. There were no deaths. Conclusion: We believe the serial checks of CK-MB, EKG and subsquent two-dementional echocardiographic sector scanning are presently the most sensitive indicators available for structural and functional cardiac injury.

Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.

BV observations for V523 Cas were performed with 1.8m telescope and 2K CCD camera at Bohyunsan Optical Astronomy Observatory, Korea, on October 27, 1999. ${\Delta}m$ light curves for 11 comparison objects were made. It was found that their light curve slopes are different each other. Factor analysis for items of slope, (b-v) , magnitude, X pixel, and Y pixel results that there is strong correlation between the slope and the location (X,Y). It might be due to problems of CCD cooling system.

Surveys of Buddhist ruins at Namsan in Gyeongju began in earnest during the Japanese colonial era, undertaken by Japanese scholars. These surveys of Buddhist remains in Namsan made during the colonial period should be seen as previous research which cannot be ignored in any in-depth study of Buddhist ruins in Gyeongju. Full-scale surveys of Buddhist ruins at Namsan began in the 1920s. Previous surveys conducted around the time of the Japanese annexation of Korea in 1910 are generally viewed as only representing preliminary investigations and, thus, have not received much attention. However, these early surveys are significant in that they led to the Buddhist ruins on Namsan becoming widely known in the 1910s and served as the foundations for later studies. The removal of the Seated Medicine Buddha from Samneung Valley in Gyeongju in 1915 and its subsequent exhibition at the Joseon Local Products Expo, which marked the fifth anniversary of the Japanese administration of Korea, was especially important in garnering attention for Namsan's wealth of Buddhist artifacts, as the statue was placed in the main hall of the art museum and attracted a great deal of interest from visitors. It is typically thought that this Seated Medicine Buddha was exhibited in 1915 because it was the most beautiful and well-preserved statue from Namsan. However, the removal of this statue was closely related to the proposed move of the Seokguram statue to Seoul around the time of Korea's annexation. The plan to move Seokguram to Seoul was primarily devised by Terauchi Masatake, and the plan, based on Ilseontongjo-ron ('日鮮同祖論'), a historical theory that prehistoric Korean and Japanese people were of the same blood, and Joseon Jeongcheasoeng-ron ('朝鮮停滯性論'), a historical theory arguing that development had stagnated in Korea, was intended to be a visual demonstration of a new era for Korea. This new era was to proceed under the rule of the Japanese Empire through the dissolution of Gyeongbokgung, the symbol of the Joseon Dynasty, which would be replaced with past glories as symbolized by the statue of Buddha. However, as the plan floundered, the replacement for Seokguram in Seoul ended up being none other than the Seated Medicine Buddha of Samneung Valley. Surveys of the Seated Medicine Buddha began in 1911, administered by Sekino Tadashi, but he likely learned of the statue's location from Moroga Hideo or Kodaira Ryozo, Japanese residents of Gyeongju. It is also probable that these Japanese residents received a request from the Japanese Government General of Korea to find a Buddha statue that was worthy of being displayed at exhibitions. In this way, we can say that the transfer of the Seated Medicine Buddha to Seoul was the result of close cooperation between the Government General, Sekino Tadashi, and Japanese residents of Gyeongju. This also had the effect of removing the magical veil which had shrouded the Buddhist ruins of Namsan. In other words, while the early surveys of Buddhist ruins on Namsan are significant, it is difficult to argue that the surveys were undertaken for purely academic purposes, as they were deeply related to the imperial ambitions of Governor-General Terauchi which encompassed the plans to move Seokguram to Seoul and the successful hosting of the 1915 Expo. It should also be pointed out that the failure of the plan to move Seokguram to Seoul and the preservation of the Seated Stone Buddha of Mireuggok at Namsan was in no small part due to resistance from Korean residents in Gyeongju. Although it is not described in detail in the paper, research is needed which shows that the Korean residents of Gyeongju were not simple bystanders, but agents of history.

We describe the case of primary pulmonary paraganglioma in a 37-year-old woman who presented recurrent, severe cough. Computed tomography revealed a lobulated inhomogeneous enhanced mass with endobronchial protruding lesion suspected to be lung neoplasm, located in the upper lobe of the left lung. Bronchoscopic biopsy showed chronic inflammation with granulation tissue which was not in accord with the radiologic findings. Subsequently, a left lower sleeve lobectomy was peformed. Histological analysis of the resected tumor proved to be compatible with pulmonary paraganglioma. Primary pulmonary paragangliomas are very uncommon tumors. So we report this case with literature review.

This paper deals with a review of the structure and production techniques of the Dried-lacquer Amitabha Buddha statue enshrined in Geungnakjeon Hall of Simhyangsa Temple, located in Daeho-dong, Naju-si, Jeollanam-do, Korea. To achieve this goal, X-ray date and two rounds of field research were performed. The data collected were reviewed, and a sample peeled off from the damaged part was analyzed to investigate the structure and material of the background layer. The results revealed that the Simhyangsa Temple Buddha statue was an almost empty Dried-lacquer(Hyeopjeo) Buddha statue where wood core had not been framed and inserted in the statue. It was thus observed that considering that the clothes wrinkles clearly remained, the same one as the irregularity of the outer clothes wrinkles, the Dried-lacquer layer was lifted made in an almost complete shape in the process of forming the clay figure as the origin form. The statue was found to be diagonally incised from the top of the head to the back of the neck to remove the clay and wood core. But in other sites, no incision was confirmed. It was observed that on the site of the head where the incision was made, an adhesives(lacquer or paste) was used. In addition, the black eyes were impacted with beads and the ears, hands, bands, and knots were made of wood. These features are identically shown in the Dried-lacquer Amitabha Buddha statue from Seonguksa Temple, known as a work of the late Goryeo dynasty; the Seated Dried-lacquer Buddha statue in Okura Museum of Art in Tokyo, Japan; the Seated Dried-lacquer Amitabha Buddha statue from Jungnimsa Temple, know as a work of the early Joseon dynasty; and the Seated Vairocana Buddha statue in Bulhoesa Temple, the Seated Dried-lacquer Amitabha Buddha and the Seated Dried-lacquer Buddha statue from Silsangsa Temple. The analysis of the back layer demonstrated that the ground layer and the red lacquer were the production of the time. In particular, the bone ash used for the ground layer was also coated for the ground layer of Buddha statues as well as for the production of the lacquerware during the Goryeo dynasty. It was also found that gold mending was conducted more than twice even in modern times and that the layer of the production time was well preserved despite gold mending several times.

Sternal fractures, once thought of as an uncommon phenomenon, have occurred with an increasing frequency, paralleling the incidence of motor vehicle accidents. The tremendous force necessary to cause sternal fracture and this bone's prominent position overlying major intrathoracic and mediastinal structures, have important implications in the assessment and treatment of patients. This evaluation is based on the review of 72 patients of traumatic sternal fracture treated at the Department of Thoracic and Cardiovascular Surgery, Seoul Adventist Hospital during the last 4 years from March 1993 to February 1997. The frequency was 12.2% of nonpenetrating chest trauma and average age was 43.2 years old. Automobile accidents(84%) and sternal body fractures(95.8%) with anterior displacements(19.4%) was the most common cause and fracture site. Increase of cardiac isoenzymes was more frequent and higher in sternal fracture than chest contusion but there was no relationship between the time to take normalization of them and the mode of trauma.

This research argues that Pansori had patrons in its development. Patrons are commonly discussed aspect of history of any art form. Pansori is no exception. While Pansori originally began as the art of the common people, Yangban class became the primary audience. This paper examines the role of royal family of Choson dynasty in development of Pansori. Heungseon Daewongun (흥선대원군) in particular was a Pansori aficionado. The record around Daewongun's involvement to Pansori proves that heavy monetary investment was made. He hosted Pansori competitions and sponsored creation of Pansori tradition, Boseong Sori (보성소리) and Gangsanje (강산제). Also the aspect of Pansori patronage lies not just in Yangban class, but also in Jung'in class, which is roughly analoguous to European bourgeois in that they were not of Yangban class, but had gained monetary status, and had aesthetics of both Yangban and commoner class. I argue that Heungseon Daewongun's ties to the Jung'in class is reflected in his actions towards Pansori artists. The traditions he had sponsored have important characteristics, including sophisticated lyrics heavily utilizing Classical Chinese poetry, highly artistic musical composition, and conservative Confucian ethics. Those characteristics indicate that the Pansori traditions sponsored by the royal patrons have changed to cater to their artistic taste and philosophy. This paper conducts a textual comparative analysis between Gangsanje Pansori Jeokbyeokga (강산제 판소리 적벽가), Dongpyeonje's Pansori Jeokbyeokga (동편제 판소리 적벽가), and Seopyeonje Pansori Jeokbyeokga, who share the same plot yet offers a stark differences in tone, philosophy, and sense of humor. Daewongun was a primary sponsor of Pansori, which proves that Yangban class and the royal family have played important role as patrons of Pansori.

Malignant flrous histiocytoma is a rare deep-seated pleomorphlc sarcoma, although its incidence Increasing. In this report, we present a case of a malignant fibrous histiocytoma, arising in the left chest wall in a 37-year-ol4 male patient. He underwent radical on bloc resection which include excision of tumor on left upper chest wall with resection of ribs from the first to third, left upper lo ectomy and chest wall reconstruction with Marled Mesh. However, he had local recurrence and distant metastasis within 12 months of the original operation. Malignant fibrous histiocytoma is an agrressive disease entity, with a propensity for early and distant spread.

A 55 year-old man hit a vehicle while riding a bicycle. He was diagnosed as left hemopneumothorax, multiple rib fracture, cerebral hemorrhage, and skull fracture. Initially he suffered from hypoxia requiring 100% oxygen with a mechanical ventilator. Finally he became hypotensive. Venovenous extracorporeal membrane oxygenation (ECMO) was initiated to support patient's gas exchange. Because hypotension and left ventricular dysfuction persisted, we converted the mode of support to veno-arterio-venous ECMO. Over four days of intensive care, we could wean off ECMO. The patient went to rehabilitation facility after 45 days of hospitalization. Although trauma and bleeding are considered as relative contraindication of ECMO, careful decision making and management may enable us to use ECMO for trauma-related refractory heart and/or lung failure.
