Background: Hyperhidrosis of the palms, axillae and face has a strong negative impact on social and professional life. The present existing non-operative therapeutic options seldom give sufficient relief and have a transient effect. A definitive cure can be obtained by upper thoracic sympathectomy. However, this is offset by the occurrence of a high rate of side effects, such as embarrassing compensatory sweating. Material and Method: From Sep. 1997 to Feb. 1998, 89 cases of the needle(2 mm) thoracoscopic thoracic sympathicotomy were performed. The second thoracic ganglion was resected by cutting with a endoscissors. Result: A bilateral procedure takes less than 25 min and requires just one night in hospital. There have been no mortality or life-threatening complications. One patient(<2%) required intercostal drainage because of pneumothorax. Primary failure occurred in one cases(<2%) and recurrent hyperhidrosis occurred in no cases. The patients with failure was successfully re-sympathicotomy. At the end of postoperative follow-up(median 3 months), 96.6% of the patients were satisfied. Compensatory sweating occurred in 57 cases(64.0%) with fourteen of those cases classified as either embarrassing in 10 cases(11.2%) or disabling in 4 cases(4.5%). Conclusion: Endoscopic transthoracic sympathicotomy is an efficient, safe and minimally invasive surgical method for the treatment of palmar and craniofacial hyperhidrosis.

Infective endocarditis that involves the right side of the heart has been estimately 5% of all cases of infective endocarditis. It has been shown that about 70% of right-sided heart infective endocarditis cases have preexisting congenital heart disease or acquired valvular lesion. It would occur in intravenous drug users or end-stage renal disease patients with indwelling venous dialysis catheter. Antibiotic therapy is more effective in the right and, when it fails, the consequence of valve disruption and emboli are less. Patients receiving long-term hemodialysis are a unique population with regard in the risk of bacteremia and subsequent infective endocarditis. We experienced one case of the active infective endocarditis with right atrial vegetation without tricuspid or pulmonary valve involvement in patient with end-stage renal disease receiving long-term hemodialysis, who needed surgical correction after medical treatment failure. Then we reported it with references that right-sided heart infective endocarditis is rare, but difficult to diagnose, life-threatening because of delayed medical treatment.

The formation of knowledge of the people of Korean society is the social practices of collective subjectivity. Subjectivity is the truth of the self, which is incessantly created, questioned and modified in the milieu of self-reflection. In an attempt to examine the hermeneutics of the subject of Korean society, a conceptual framework is proposed, which, with the notion of life embedded, consists of a historical sequence of the popular, minjung, multitude, people and community. The period of 1960s saw the ambiguous mass of lifes floating, the individual with his/her own interior world of consciousness emerge. The ideological solidarity is formed in the the next two decades, in contestation with immediate and physical threatening such as poverty and dictatorship. The democratization of Korean society and the global expansion of neoliberal regime gave a re-birth of multitude and people which is characterized with their pursuit of the co-existence and co-realization of singularity and universality on the ethical principle of the open and communicative radicality.

This paper is consisted of the thesis that the decontextualized limitation of media cultural studeis in Korea should be overcome by walking into and linking with today's urban crisis and everyday life. It proposes us to become the flaneurs who do not hesitate to go to, think of, and experience actively the city in crisis under the capital/state domination. It's conclusion would be that we must practice participation observation at the fields and thus recover the critical element of cultural studies writing, by entering into the city and seeing at the features of crisis routinely expressed and symptomatically appear in there. For and before this, the author will first of all pay attention to John Fiske in later period, who was merely perceived and falsely regarded as an active audience theorist. He will also review de Certeau from whom Fiske has borrowed the concept of tactics, and Berman who has further practiced the very spatial tactic. The paper is prepared so as to expand the ideas and thoughts of them who have gone beyond the boundary of text, audience and onto the context of urban space. It's goal is much more than rescuing, recovering Fiske's alternative trajectory. It tries to reconstruct the tradition of urban media cultural studies critically connected with the dangerous, life-threatening capitalist condition. Furthermore, by filling up the theoretical vacuum left behind disconnected and cut away from Fiske, it attempts to find a vision, prospect of cultural studies that will actively engage themselves dialectally with dangerous yet hopeful life of the city and its popular masses.

Cement-retained implant prosthesis has several advantages in the esthetic and occlusal aspects. However, the difficulty of the retrievability and the possibility of peri-implantitis induced by the cement excess would be a threatening factor to the implant prognosis. Peri-implantitis resulting from the remaining cement could occur later on to the patients with periodontitis history. Retention can be controlled by selecting the right cement type. Retention of the cement was the strongest in the resin cement, followed by resin modified glass ionomer cement, poIycarboxylate cement, zinc phosphate cement and glass ionomer cement. Retention of the provisional cement weakened after thermocycling. Other factors such as the abutment number, abutment alignment, height and taper of the abutment can also affect the total retention. To the success of the cement-retained prosthesis, it's important to select the right cement for the clinical purpose. The prosthesis should be fabricated in accordance with the biomechanical requirements. The prosthesis should be cemented with the techniques to reduce the excess cement as much as possible. In addition, the excess cement should be identified using the radiography and carefully removed.

Background: In malignancies, detection of metastatic foci is of value in making therapeutic plans for treatment of disease and prevention of life-threatening complications. Common sites for metastasis of bronchogenic cancer include lymph nodes, liver, brain, adrenals and bone. Skull, vertebrae, ribs and long bones are common sites for bone metastasis. But in epidermoid carcinoma, the incidence of bone metastasis is relatively low and especially to the distal phalangeal bone is rare. Methods: We experienced a case of epidermoid carcinoma with the first distant metastasis to the fifth distal phalangeal bone, right toe. Results: The initial stage in the diagnosis of epidermoid carcinoma was T4N3MO. During the third round of anticancer chemotherapy, we recognized the distant metastasis to the fifth distal phalangeal bone for the first time. Localized abnormal findings were noted by bone X-ray and scanning. By a histopathologic examination of the amputated toe, we confirmed the metastasis of epidrmoid bronchogenic carcinoma. Conclusion: If localized abnormal finding is discovered at an unusual site for metastasis, we recommend physicians to consider the possibility of metastasis even though it is very low.

Methotrexate is commonly used in rheumatoid arthritis as an anti-inflammatory agent, but treatment with methotrexate can lead to severe side effects, especially pulmonary complication. Interstitial pneumonitis is one of the most important pulmonary adverse effects of methotrexate and most patient present with a subacute febrile illness and peripheral eosinophilia is seen in about a half of patients. Almost all patients have abnormal chest roentgenograms and bibasilar interstitial infiltration with alveolar pulmonary consolidations is the most characteristic finding. Interstitial inflammation with mononuclear cell infiltration is a characteristic pathologic feature and findings that suggest acute hypersensitivity pneumonitis, such as bronchiolitis, granuloma formation with giant cells, and infiltration with eosinophils are often present. Methotrexate-induced pneumonitis is a potentially life threatening and unpredictable complication but it is difficult to make a definite diagnosis in the absence of high index of clinical suspicion. Early recognition and appropriate management may avoid the serious outcome. Herein we report a case of methotrexate-induced pneumonitis in a patient with rheumatoid arthritis.

Iron supplements such as ferrous sulfate tablets are usually used to treat iron-deficiency anemia in some elderly patients with primary neurologic disorders or decreased gag reflexes due to stroke, senile dementia, or parkinsonism. While the aspiration of ferrous sulfate is rarely reported, it is a potentially life-threatening condition that can lead to airway necrosis and bronchial stenosis. A detailed history and high suspicion of aspiration are required to avoid delays in diagnosis and treatment. The diagnosis can be confirmed by bronchoscopic examination and a tissue biopsy. Early removal of the aspirated tablet prevents acute complications, such as bronchial necrosis, hemoptysis, and lobar consolidation. Tablet removal is also necessary to prevent late bronchial stenosis. We presented the first case in Korea of a ferrous sulfate tablet aspiration that induced severe endobronchial inflammation.

Korea is a country having shortage of natural resources, but to overcome this issue and to nurture national competitiveness it is challenging for national-lead economic policy, citizen's dedicated efforts and technological innovation for achieving economic growth. Since the financial crisis, the government has boldly promoted policies to nurture venture companies to make structural adjustments for the sophistication of the industrial structure and job creation. Various policies for establishing the foundation of the entrepreneurial ecosystem in which the process of start-up, growth, recovery and reinvest are virtually circulated are presented by the Business Incubators. Recently the Business Incubators neither present a direction differentiated from the vocation of Business Incubator, and nor the operating methods for leading the changing of Business Incubator environment, which threatening the role of Incubating and growing early startup companies. In order to explore the development change of the business incubator, in this research we analyzed the published papers from 1998 to 2016 of business incubator government polices, research methods, related research topics and other major variables. The analysis of the research trends of business incubator revealed the lack of depth case studies, diversity of research topics, and the study of certain limited variables. For the development of the business incubator, case studies of the institutions which carried out excellent incubator and research on the incubation system of the institutions, that are similar to the incubation center are required. This research suggest further research on the case studies of excellent business incubator and agencies, and the center director and manager, which is the center of human resources, and hopes for the revitalization of business incubator researches.

This paper consists of two parts: In the first part, we describe our work to build hierarchical knowledge base of digital library patron's research interests and learning topics in various scholarly areas through analyzing well classified Electronic Theses and Dissertations (ETDs) of NDLTD Union catalog. Journal articles from ACM Transactions and conference web sites of computing areas also are added in the analysis to specialize computing fields. This hierarchical knowledge base would be a useful tool for many social computing and information service applications, such as personalization, recommender system, text mining, technology opportunity mining, information visualization, and so on. In the second part, we compare four grouping algorithms to select best one for our data mining researches by testing each one with the hierarchical knowledge base we described in the first part. From these two studies, we intent to show traditional verification methods for social community miming researches, based on interviewing and answering questionnaires, which are expensive, slow, and privacy threatening, can be replaced with systematic, consistent, fast, and privacy protecting methods by using our suggested hierarchical knowledge base.
