The purpose of this study is to find problems of Geographical Cluster and to analyze relationships between problems of a Geographical Cluster and its performance. The problems of geographical cluster include those of technical fusion, increase of incidental expenses, conditions of settlement, and absence of industrial infrastructures, and performance factors are satisfaction with the cluster policy and within cluster firm's performance. According to the results of analyses based on the data collected from 75 firms located in the Gumi electronic industry cluster complex, first, problems of technical fusion, and absence of industrial infrastructures had a negative(-) effect on satisfaction with the cluster policy. Second, absence of industrial infrastructures had also a negative(-) effect on within cluster firm's performance. In the conclusion, further discussion, limitation of this study and future direction were suggested.

A rare anomaly, Cor triatriatum dexter combined with pulmonary stenosis and patent foramen ovale in a 2-years- old female is presented. Abnormal embryologic development of the right sinus venosus valve caused partial membranous septation of the right atrium. Most cases have been recorded at necropsy either as an incidental finding or in association with severe congenital heart disease. In this case, Cor triatriatum dexter was diagnosed preoperatively by cineangiography and echocardiography.

Phalloides syndrome has usually occurred after incidental mushroom ingestion. It is sometimes difficult to differentiate toxic mushrooms from edible ones, especially in lay person because of their morphological similarities. In Korea, Amanita virosa and Amanita subjunquillea have been reported as a cause of fulminant hepatic failure in mushroom poisoning (phalloides syndrome). We report a case of phalloides syndrome who came to death with fulminant hepatic failure even though we planned liver transplantation and used T-PLS(R) (Twin Pulse Life Support) for hemodynamic support while waiting for the donor.

Recently, the trauma patients have been markedly increasing due to the vast increase of traffic accident, industrial disaster, incidental accident and violence. The authors have analysed of 22 patients of thoracic injuries combined with abdominal injuries and summarized as follows. The ratio of male to female was 3.4:1 and their age distribution was from 5 years to 68 years and mean age was 34.4 years. The etiologies of injury were traffic accident, stab wound, fall down and violence. Associated injuries were fractures, bowel perforation, kidney rupture, head injury, liver laceration, spleen rupture and so forth. The modes of treatment were closed thoracostomy, repair of diaphragm, ruptured bowel repair, explo-thoracotomy, splenectomy, hepatic lobectomy in this order of frequency. The postoperative complications were atelectasis, wound infection, pneumonia, empyema, acute renal failure, respiratory failure and bleeding. The mortality rate was 13.6% [3/22 and the causes of death were respiratory failure 1 case, acute renal failure 1 case and hypovolemic shock 1 case.

Eight surgically treated patients with leiomyoma of the esophagus are presented. The patients were 6 men and 2 women whose ages ranged from 20 to 50 years. One of them was asymptomatic, while the remaining seven had mainly dysphagia and weight loss. The preoperative diagnosis was made in 6 cases. One patient had coexisting esophageal carcinoma masking the presence of the leiomyoma and masking the lesion an incidental operative funding. The other which was asymptomatic was diagnosed as a mediastinal tumor preoperatively. Six patients were treated by thoracotomy and enucleation of the tumor. Two patients were treated as esophagectomy and esophagogastrostomy. There were no operative deaths, and the overall results were excellent.

Castleman`s disease, giant lymph node hyperplasia, is a rare benign disease. The lesion usually consists of a single node, unassociated with any abnormality of the adjacent lymph nodes or other organs. In the first accounts of giant lymph node hyperplasia of Castleman, the lesion was described as solitary and localized to the mediastinum, which is still the most frequent site of involvement. The disease occurs in all age groups and there is no particular sex preference. It is symptomless and is usually detected on chest films as an incidental finding. On a single involvement, it does not recur after excision, whether total or partial, and the main indication of operation is to rule out more serious tumors. Recently multicentric form appears to be a variant of classic giant lymph node hyperplasia and is associated with significant morbidity and mortality. Histologically, two distinct types have been reported; hyaline-vascular and plasma cell. The hyaline-vascular type of lesion is much more common than the plasma cell type. We report two cases of the hyaline-vascular type of Castleman`s disease.

Bronchogenic carcinoma with subcutaneous metastasis is rare, and the incidence ranged from 1.0 to 3.0 %. Therefore metastatic nodules are incidental findings in some instances. The distribution in order of frequency Is as follows: chest wall, scapular region, abdominal wall, course of spine, upper extremities and scalp etc, and mos. of nodules are between 0.5-2.0 cm in diameter. In this report, we present one case of a 54 year old male having bronchogenic carcinoma (squamous cell type) with multiple subcutaneous metastases. The metastatic nodules were located in subcutaneous tissue of right posterior chest wall ($4{\times}5$ cm), frontal scalp area (two; $2{\times}3$ cm, $0.5{\times}0.5$ cm), left scapular region ($1{\times}1$ cm) and left iliac crest ara ($1{\times}11$ cm).

Anomalous origin of right coronary artery from pulmonary artery is a rare congenital cardiac anomaly. Anomalous right coronary artery often be a incidental finding without serious cardiovascular sequale. The only characteristic physical finding is a continuous murmur with diastolic accentuation. There are no diagnostic EKG or chest X-ray changes. Diagnosis is made best by selective left coronary arteriography showing retrograde filling of right coronary artery from collateral vessels. Here, we present a case of twenty-four months old aged girl with anomalous origin of right coronary artery combined with pulmonary stenosis. This is the first pediatric patient with anomalous right coronary artery and the first patient to have surgical correction for this malformation.

Lipomatosis is a condition containing multiple lipomatous masses.Lipoma is a benign neoplasm composed of adult adipose tissue, and occur most often in the fifth or sixth decade and rarely in the pleura. Pleural lipomas are usually asymptomatic and revealed as an incidental roentgenographic findings. The patient was 59 year-old male and admitted because of dyspnea-on-exertion for 30 years. Chest CT revealed right pleural mass abutting on the chest wall, measuring minus 80 hounsfield units. The mass was resected with calcified pleural plaque and confirmed to be lipomatosis with collagenous fibrosis arising from viserai pleura.
