Background: The large caliber catheter used in the treatment of pneumothorax causes great damage to the chest wall and organs. The purpose of this study was to prove that the use of a smaller caliber catheter is effective in treating pneumothorax with decreasing admission period and that the recurrence rate of spontaneous pneumothorax is low. Methods: Patients who had been admitted for treatment of first time occurrence of pneumothorax between May, 2004 and December, 2008 were included in the study. The caliber of catheter used this study is 18 Guage (1.2mm). The efficacy of treatment, admission period and recurrence rate of treating pneumothorax with small caliber catheter were compared to the control group using a tube thoracostomy for treatment. Results: The admission period for primary spontaneous pneumothorax was 10.8$\pm$3.6 days for the group (n=68) using tube thoracostomy compared to 4.5$\pm$1.3 days for the group (n=31) using the small caliber catheter (p<0.05). There was no statistically significant difference in recurrence rate between the two groups. Conclusion: The use of a smaller caliber catheter for the treatment of pneumothorax reduces the admission period without a significant increase in recurrence rates.

International volunteering in education is one of activities in volunteering. Volunteers have been recognizing that educational activities play an important role in volunteering. Recently, there is an increase of participants and various supports for educational volunteering in South Korea. However, regardless of the essential meanings in which activities commonly attempt for deriving local sources in terms of human and resources, many participants in volunteering take advantages of their own purposes and providing their supports in terms of a mercy. This study asserts that this situation comes from the lack of theoretical understanding of volunteering. Therefore, this study realizes a need of providing a theoretical background and purports to suggest it for international volunteering in education. It is the critical pedagogy. Critical pedagogy tries to deconstruct false-consciousness of the oppressed through education. And, it emphasizes that people could have autonomy and self-directed sovereignty. Accordingly, critical pedagogy should be a theoretical background of activities for deriving human's autonomous consciousness and their own resources. Thus, it might be a theoretical background for international volunteering in education.

The purpose of this study is to find out ways to enhance corporate value by using more efficient use of non-reflux Income which is commonly considered in existing corporate income tax refund and newly introduced investment and mutual aid promotion tax. Specifically, we analyzed the effect of income tax return income and income tax return on wages and fixed - asset investments, which are commonly considered in the two tax systems, on firm value. As a result of the analysis, it was confirmed that short-term internal reserves and income reflux activities had a negative impact on firm value, and long-term internal reserves and income reflux return had positive effects on firm value. It is recommended not to formulate uniform criteria such as the ratio of income refund activity to the contents of tax, but to apply the tax refund to the internal taxation system and the taxable income source.

This study aims to examine primary determinant for medical expenditure depending on different age and income brackets. The age and income brackets are simultaneously taken into account for a forming of structural models, and GARCH methodology is utilized in analyzing the model. Empirical evidence reveals that no matter how general medical care system is appropriately operated, medical expenditure is vulnerable in taking care of potential socially-disadvantaged class and the group of catastrophic medical expenditure as long as the age and income brackets concern, simultaneously. It signifies that more elaborately designed medical-related policy seems to be established to improve its effectiveness. On the contrary, ageing society is comparatively well-treated by public health law and act on long-term care insurance for the aged.

It is expected to continue to increase the number of people who enjoy marine and water sports due to the increase of leisure time because of income increase, the five-day workweek, etc. However, in the safety awareness, the development of equipment is just in the early stage. Established system for fundraising is required for Korean marine and water sports to be developed first. Should the fund be spent on the safety and development of domestic equipment for marine and water sports, it would make for a safer and more enjoyable sports for the people. The profit return measures of motor boat race, among marine and water sports, are surveyed and analyzed to suggest the measures stated above. Japanese legal structure and the profit return measures on motor boat race, which are about 60 years ahead than Korean systems, were analyzed and led to suggest the establishment of professional institutions which promote motor boat, etc. and the legal improvement for funding.

We defined factors affecting the postoperative outcome in adult cardiac surgery with cardiopulmonary bypass (CPB). Thirty-two adult patients scheduled for elective cardiac surgery participated in this study. Levels of leukocyte, glutamic oxaloacetic transaminase (GOT), troponin-I (cTNI), interleukin-6 (IL-6), D-dimer and neuron-specific enolase (NSE) were significantly elevated, whereas platelet count declined in cardiac surgery with CPB. GOT and D-dimer levels at CPB-off each had a positive significant correlation significantly with 24 hrs-bleeding, total bleeding, mechanical ventilatory assist time, ICU stay time and length of hospitalization. BUN levels at CPB-off were directly related to total bleeding, mechanical ventilatory assist time, ICU stay time and length of hospitalization. Platelet count at CPB-off was inversely related to mechanical ventilatory assist time, ICU stay time and length of hospitalization. Creatinine concentration at CPB-off interrelated positively with mechanical ventilatory assist time and ICU stay time. NSE levels at CPB-off had a positive relationship with postoperative 24 hrs-bleeding. The length of hospitalization was prolonged proportionally to the elevation of cTNI levels in cardiac surgery. Aortic cross-clamping and total CPB times also related with increase of 24 hrs and total bleeding volumes and the length of hospitalization. IL-6 and ET-1 had no mutual relation with any postoperative outcome. These data suggest that GOT, BUN, creatinine, D-dimer and platelet levels are the most important factors affecting postoperative outcomes and patient's recovery in adult cardiac surgery with CPB.

In the growth of the government's investment in national R&D project and the abuse of research expense, an effective control and management mechanism is strongly demanded. However, an excessive regulation might hinder the R&D performance, which also endangers the underlying objective of R&D policy. Especially, an excessive regulation on the R&D expenditure may damage the SMEs (Small and Medium sized Enterprises) where securing an adequate level of R&D funding is vital. This study investigates the R&D funding and R&D performance of SMEs participating in the national R&D project by using fixed effect panel model. As a result, this paper reveals the effectiveness of 'Government R&D subsidy'. However, that of 'private R&D fund' is not supported strongly. Also, this paper empirically demonstrates the efficiency of both 'Government R&D subsidy' and 'Private R&D fund' as the R&D costs are spent discretionarily (as the degree of 'Indirect Cost Ratio' increases). Especially, the effectiveness of 'Private R&D fund' can be moderated by 'Indirect Cost Ratio'. On the basis of the conclusions, this paper draws an implication that can increase R&D performance of SMEs through the interactions of manifold administrative values (i.e. effectiveness, efficiency and responsibility).

Lumbar Sympathectomy is a surgery for plantar hyperhidrosis, vascular and other reflex sympathetic diseases and has a various indications and physiologic effects. However it is not performed actively compared to thoracic sympathectomy because of its invasiveness. Therefore, we tried to perform lumbar sympathectomy using mediastinoscopy with small incision and introduce this new surgical technique. Material and Method: From July 2003 to December 2004, 18 patients undewent lumbar sympathectomy with mediastinoscopy at Inje University Sanggye Paik Hospital. There were 12 males and 6 females whose mean age was 24.3$\pm$8.2 years ranging from 18 to 67 30 cases of lumbar sympathectomy was performed with mediastinoscopy of which 24 cases were for plantar hyperhidrosis and 6 cases for other diseases. Result: Mean operation time was 37.2$\pm$12.5 minutes and mean post operation hospital stay was 3.1$\pm$2.2 days. There was one post sympathetic neuralgia and one peritoneal opening. Conclusion: Lumbar sympathectomy using mediastinoscopy is a simple and effective technique and has the advantage of cosmetics, post operative pain and hospital stay. However, further studies with large number of cases should be carried out for better outcome.

전기기술은 기술의 특성상 민간에 대한 유인이 적은 공유성 기술이나 대학 또는 기업이 감당하기 어려운 대형복합기술의 비중이 높으며, 최근 들어 전력산업의 구조개편 등에 따라 국가적 기술개발수요가 확대됨과 동시에 전기기술의 이용분야 확대와 타 기술과의 융합화 및 대형화로 신기술수요가 늘어나고 있다. 현재 우리 나라의 전기기술 R&D체제에서는 공공기술에 대한 사각지대가 발생하고 있음에도 불구하고 국가차원의 R&D 공급이 미약하여, 거대한 시험설비와 첨단고가장비를 필요로 하는 시스템기술로 일부 기기나 시스템운용을 제외하고는 개별기업이나 전력회사에 대한 기술개발 유인이 크지 않으며, 따라서 전기기술분야의 R&D 실태 파악과 역할에 대한 검토를 통해 R&D 주체별 기관특성에 맞는 국가 R&D체계의 정립이 필요한 실정이다. 따라서, 앞으로는 전기기술분야의 국가 R&D 목표 및 기본전략에 따라 국가 R&D 자원의 규모, R&D 주체간의 역할분담 등 전반적인 R&D 체계의 구축이 선행되어야 하며, 이를 통해 기관별 Mission 및 고유기능을 토대로 전문성 제고와 특성화를 유도할 수 있는 연구여건의 조성이 시급하다 하겠다. 특히, 장기대형연구, 원천기술연구, 기초기반연구, 연구기반구축, 인력양성 등 필수적 국가기능에 대해서는 기관별 특성에 따라 안정적인 역할수행이 가능하도록 역할분담 및 정책적 지원을 하되, 그 밖의 영역이나, 민간 및 전력회사의 독자적인 R&D에 대해서는 경쟁 및 협력을 통한 연구효율성 향상을 유도하는 방향으로 나가는 것이 바람직할 것이다. 국가적 전력기술 R&D의 효과적인 수행과 실효성 확보를 위해서는 재원확보가 선행되어야 하며, 이를 위한 방안으로는 기존의 전력사업자에게는 기술개발충당금 또는 전기요금 중 일정비율을 국가적 R&D 재원으로 설정할 수 있을 것이며. 신규 사업자에게도 규제비용의 차원에서 일정 부담금을 부과하는 방법이 가능할 것이다. 이러한 재원을 가지고 사업성격 및 R&D 유형에 따라 역할분담에 따른 지원, 정책적 사업, 경쟁적 사업공모 등을 통해 지원분야 및 규모, 대상기관 등에 대한 선별적인 지원이 이루어져야할 것이다.
