Nontraumatic, incracranial giant aneurysm has rarely been reported as the cause of the spontaneous subarachnoid hemorrhage in childhood. Multiple, dissecting giant aneurysms on the left middle cerebral artery with sudden onset of headache in a 14-year-old girl were successfully clipped and followed by complete relief of symptoms. The rarity and characteristics of such lesion in childhood and its successful surgical treatment are discussed briefly.

Germ-cell tumors (GCTs) are common in the central nervous system. GCTs are highly sensitive to radiotherapy and chemotherapy and can be cured without radical surgery. However, this tumor produces nonspecific imaging findings, and its rarity can make diagnosis challenging. Here we report a case in which the first diagnosis was uncertain and follow-up imaging revealed intramedullary germinoma. The patient underwent chemotherapy and radiotherapy after the diagnosis.

Intestinal T-cell lymphoma is a rare and aggressive form of non-Hodgkin lymphoma. Owing to its rarity and variable manifestations, intestinal T-cell lymphoma is usually diagnosed at an advanced stage. Therefore, it may be accompanied with serious complications at the time of diagnosis. Herein, I reports a case of intestinal T-cell lymphoma with multiple severe complications.

The criteria which have been used for the assessment of wildlife conservation values and particularly botanical values during the last decade, 1969~1986, were reviewed in order to select an appropriate set of criteria applicable for Korea. Fifteen studies, including studies of particular sites reviews of ecological evaluation are reviewed. Four criteria, rarity, diversity, size & extent and naturalness were used in more than half of these studies reviewed. The sixteen components were arranged with the scale of the sites, in view of the Korean situation. The human Interference, ecological fragility. as well as rarity, etc. were major components to be considered at small scale sites. In the contrary, area, diversity position in ecological and geographical unit, and naturalness, etc. considered the major components at larger scale sites. The components such as uniqueness, typicalness, research and educational, etc. were considered both applicable. Although this criteria should be tested by applications in the field and amended there after, It will be one of the first-step to evaluate of the protected areas, as well as specific plant species in the future.

This study was performed to analyze of market segmentation of outpatient services on the based of consumption values. Self-reported questionnaires of six hospital outpatients 600 were analyzed by six consumption values categories: functional values, social values, emotional value, rarity value, situational values, health related values. The main results of this research is as following; 1. The consumption values were significantly different in that sociodemographic characteristics. Especially, the more older aged group, farmer and married people, the more they preferred to functional value, social value, emotional value and rarity value than younger aged group and unmarried people. But in the cases of situational vaue, younger aged people and white-callar workers recognized more positively. Also, housewives, married people and female recognized more positively than white-callar workers, unmarried people and male. 2. In the results of CHAID analysis, market of general hospital were analyzed by 9 categories and major market were groups who ignored or were unconcerned about newness/classiness and preferred to nearness to residence. The market of university hospital were analyzed by 8 categories and major market were groups who considered to reliability/social reputation importantly. The market of corporate hospitals were analyzed by 8 and major market were group who considered to classiness/newness importantly. Therefore, above results show that health care market can be divided to various market by demand and market segmentation is very important for marketing strategy.

In this paper, we describe a new summarizing method based on a graph-based and a sense-based analysis. In the graph-based analysis, we convert sentences in a document into word vectors and calculate the similarity between each sentence using LSA. We reflect this similarity of sentences and the rarity scores of words in sentences to define weights of edges in the graph. Meanwhile, in the sense-based analysis, in order to determine the sense of words, subjectivity or objectivity, we built a database which is extended from the golden standards using Wordnet. We calculate the subjectivity of sentences from the sense of words, and select more subjective sentences. Lastly, we combine the results of these two methods. We evaluate the performance of the proposed method using classification games, which are usually used to measure the performances of summarization methods. We compare our method with the MS-Word auto-summarization, and verify the effectiveness of ours.

Ameloblastomas are benign epithelial neoplasm of the jaw comprising approximately 1-3.3% of all odontogenic cysts and tumors. Although most are microscopically benign, they are generally considered to be locally aggressive and destructive, exhibiting a high rate of recurrence. Treatments of them contain the conservative treatments on unilocular types and radical treatments on multilocular types. Classifications based on the histologic features of ameloblastoma generally included the follicular, plexiform, acanthomatous, basal cell, uncystic types. However, recently a new and unusual variant has been added by Eversole et. al in 1984, the histologic features of which are characterized by marked stromal desmoplastic proliferation. This is a case report of desmoplastic ameloblastoma in the anterior maxilla of 63 year-old female treated by block excision. This provides a brief review of the literature because of the rarity and unusual radiographic-histologic features of desmoplastic ameloblastoma.

Non-photo realistic Rendering is the one of the fields in Computer Graphics and many painterly rendering techniques have been studying. However studies about a specific painter are still in a rarity. Therefore in this paper, we studied about technique for generation of Henri de Toulouse-Lautrec's portraits. Toulouse-Lautrec was a painter in 19th century. His style of portraits was expressed as follows; the sketch was drawn by conte or pastel in croquis style and colored only focused parts like faces on the base colored area. For simulate this, we propose sequential technique about sketch style image generation and face area painting.

Gastrointestinal (GI) hemangiomas are relatively rare benign vascular tumors. The choice of an appropriate diagnostic method depends on patient age, anatomic location, and presenting symptoms. However, GI hemangiomas are not a common suspected cause of GI bleeding in children because of their rarity. Based on medical history, laboratory results, and imaging study findings, the patient could be treated with either medication or surgery. Herein, we report 3 cases of GI hemangioma found in the small bowel, rectum, and GI tract (multiple hemangiomas). Better knowledge and understanding of GI hemangioma could help reduce the delayed diagnosis rate and prevent inappropriate management. Although rare, GI hemangiomas should be considered in the differential diagnosis of GI bleeding.

Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management. We report a case of atypical carcinoid with local recurrence and pleural metastases treated by video-assisted thoracoscopic surgery lobectomy and total pleurectomy with photodynamic therapy after non-radical wedge resection.
