Since the turn of the century there has been a constant search for a satisfactory method of controlling a large intrathoracic space following lobectomy. Primarily these methods consist of thoracoplasty, plombage, and phrenic nerve paralysis which are not completely satisfactory for they may result in loss of chest wall motility or diaphragmatic function. Incising the diaphragm at its periphery and resuturing to the chest wall at a level several rib spaces higher is an effective method of reducing intrathoracic space with minimal interference with pulmonary function. It is of particular value when the anticipated space problem is in the lower part of the thoracic cavity. Five cases are presented in which the diaphragm was peripherally detached and advanced to higher levels. Two cases were following lower lobectomy and three cases were following decortication for chronic empyema in which expansion was not good enough to adequately fill the space. Results in these cases were satisfactory.

Aneurysm of the common carotid artery is uncommon. In surgery for carotid aneurysm there is the risk of endangering cerebral circulation during the period of arterial occlusion necessary for the resection. Therefore a method which will allow adequate cerebral circulation during carotid artery anastomisis is obviously to be desired. A case of aneurysm of the common carotid artery is presented in which the aneurysm was partially resected and the artery was reconstructed by end to end anastomosis. while cerebral circulation was maintained by an internal polyethylene shunt. The occurrence of this aneurysm was associated with a chronic stasis ulcer of the left fore leg. On this basis the aneurysm was thought to be of mycotic origin though this has not been proved histologically or by laboratory methods. The literature on aneurysm of the carotid artery is briefly reviewed.

The purpose of this study is to identify the key factors and estimate the non-market value of urban park using meta-regression analysis. Meta-analysis is a statistical method and useful tool to summarize the research results from independently related studies. This study used 46 estimates from 20 valuation studies on urban park and found that the type of park is the most influential factor on respondents' WTP. The parks in the neigborhood tend to have lower value whereas waterfront park appears to have highest value. The number of studies using most widely used non-market valuation methods, CVM and Conjoint Analysis, presented statistically significant results from their survey and payment vehicle for WTP. The empirical results from this study suggest that the meta-analysis is a great potential as a tool to synthesize the research results from valuation studies and provides useful information to policy makers. In order to overcome some of the shortcomings of meta-regression analysis and improve its validity and reliability, it is important to collect and produce data base on valuation studies and sufficient support to improve its quality. 본 연구의 목적은 국내에서 수행된 도시공원의 비시장가치 선행연구를 대상으로 메타회귀분석을 실시하여, 공원의 비시장가치에 영향을 미치는 요인들을 규명하고 정책적 시사점을 도출하며, 메타회귀분석의 적용 가능성을 검토하는데 있다. 메타회귀분석은 기존에 축적되어 있는 연구로부터의 정보를 추출하여 다양한 변수의 상관관계를 회귀분석으로 밝히는 기법이다. 문헌검색을 통해 도시공원의 비시장가치를 추정한 20편의 연구에서 46개의 가치 추정치가 실증분석에 사용되었다. 실증분석 결과 특정한 공원의 유형이 시민들의 지불의사에 영향을 미치고 있음을 알 수 있었다. 근린공원의 경우 여타 공원에 비하여 낮은 가치를 나타내고 있었으며, 하천의 수변공원의 가치는 높게 나타났다. 대표적인 비시장가치 평가 기법인 조건부 가치측정법과 컨조인트 분석법은 통계적으로 유의한 차이를 보이고 있었고, 설문조사 부수와 지불의사를 묻는 도구도 가치에 유의한 영향을 미치고 있음을 알 수 있었다. 본 연구의 사례분석을 통해 메타회귀분석은 선행연구 결과를 종합하고 관련 정책을 수립하는데 유용한 정보를 제공할 수 있는 분석의 틀로써 충분한 활용 가능성을 갖고 있는 것으로 판단된다. 다만, 메타회귀분석이 분명한 한계를 갖고 있는 만큼, 메타회귀분석의 정책에 대한 유효성과 신뢰성을 높이기 위하여 관련연구의 DB 구축, 개별연구의질 향상을 위한 노력 등이 뒷받침되어야 할 것이다.
