Absorbable periodontal tissue regeneration barrier membranes (total 6; domestic 4; import 2) were comparatively analyzed. In the case of the xenograft barrier membrane, the collagen product had excellent tensile strength but low strain, and the porcine pericardial membrane had good mechanical properties, but its thickness was too thick to control. The synthetic PLLA membrane manufactured by the electrospinning had a relatively low water absorption capacity. However, the hybrid barrier membrane was able to control mechanical properties and biocompatibility through proper mixing of synthetic polymer and natural polymer. DA02 (PLLA/gelatin), a newly developed hybrid absorbable periodontal tissue regeneration membrane that is entirely dependent on imports, can be applied to an absorbable periodontal tissue regeneration barrier membrane due to suitable mechanical properties and biocompatibility.

경영성과(經營成果)의 평가지표(評價指漂)는 개별조직의 목표와 제약환경, 즉 이용가능한 자원량과 개별적 특수요인 등을 고려하여 설정하여야 하며, 산업내의 특성과 동질적 비교집단을 이해함으로써 조직의 성과와 직접적으로 연결될 수 있어야 한다. 또한 조직의 평가는 부분적(部分的)인 효율성(效率性)에 편중되지 않고 투입과 산출간의 유기적인 관계를 총체적인 관점에서 분석함으로써 종합적(綜合的) 효율성(效率性)에 그 촛점이 두어져야 한다. 이러한 문제의 인식에 바탕을 두어 본 연구에서는 Charnes, Cooper와 Rhodes(1978)에 의해 처음 개발되어 주로 비영리기관의 경영성과의 평가에 많이 사용하여 온 DEA(Data Envelopment Analysis)기법을 이용하여 금융기관(金融機關)의 효율성(效率性)을 평가(評價)한다. 금융기관은 다양한 투입요소를 사용하여 다양한 서비스 상품을 제공하는 조직이기 때문에, 또 재무비율을 이용한 기존의 평가나 통계적 생산함수의 추정에 의한 평가방법은 단순히 과거의 실적을 평가하는 데 그치게 되고 객관성이 결여되기 쉽기 때문에 조직의 미래운영방향의 설정에 도움이 되지 못한다는 단점을 가지고 있다. 그러나, DEA은 다수의 투입과 산출요소를 요구하는 경우에 적합하게 설계된 분석방법이므로 금융기관의 성과분석에 적절하게 이용될 수 있다. 본 연구에서는 먼저 금융기관(金融機關)의 효율성(效率性)을 평가(評價)하는 기존의 방법을 간략하게 검토한 다음, DEA에 관한 이론적 기초와 그 특성을 검토한다. 실증분석에서는 여 수신업무(與 受信業務)를 수행하고 있는 국내금융기관들 중에서 자료의 동질성과 표본대상 기업의 수를 고려하여 은행업(銀行業)과 투자금융업(投資金融業)을 선정하고 이들 업종에 속한 37개 회사들에 대한 운영효율성(運營效率性)을 측정한다. 투입요소로 직원의 수와 영업비용을, 그리고 산출요소로 영업수익과 경상이 익을 선정하고, 3년간의 자료를 사용하여 실증분석을 한다. 분석의 결과에 의하면, 18개 전체 은행의 평균적인 효율성의 정도는 가장 효율적인 은행을 기준으로 할 때, 약 85% 수준에 그치고 있어서, 나머지 대부분의 은행들 특히 대규모 시중은행들의 경영상의 개선의 여지가 매우 크다고 할 수 있다. 5대 시중은행들간에는 효율성의 차이가 거의 없는 반면, 지방은행들간에는 매우 큰 차이가 있는 것으로 나타난다. 이는 영업지역의 제한으로 인하여 지역경제 규모가 은행의 수지상황에 결정적인 영향을 미치고 있다는 것을 반영하고 있다. 29개 단자회사를 대상으로 한 투자금융업의 경우에도 은행업의 경우와 동일하게 낮은 효율성과 지역간 격차현상이 나타나고 있다.

OSS(Open source software) pursues the freedom to have access to open source and offers several advantages, over the proprietary software, to enterprises. Based upon Rogers(1995)' innovation-diffusion process, we assume that attributes of innovations includes five characteristics of innovations: relative advantage, compatibility, complexity, trialability, and observability, and that firms' perceptions of these characteristics predict the rate of adoption of OSS. To test this hypothesis, we presents a survey result from 201 companies and institutions concerning the use of OSS. Statistical analysis shows that adoption is highly correlated with each of those characteristics of innovations, but the regression analysis indicates that only compatibility and observability have effects on the adoption of OSS. This implies that intrinsic value of OSS is important, but unless the appropriate service package for improving IT environment is provided, it is not easy to change the perspective of corporate customers more favorable toward OSS use. As a conclusion, the academic and practical implications are also discussed.

Current artificial heart valves have several disadvantages, such as thromboembolism, limited durability, infection, and inability to grow. The solution to these problems would be to develop a tissue-engineered heart valves containing autologous cells. The aim of this study was to optimize the protocol to obtain a porcine acellular matrix and seed goat autologous endothelial cells on it, and to evaluate the biological responses of xenograft and xeno-autograft heart valves in goats. Material and Method: Fresh porcine pulmonic valves were treated with one method among 3 representative decellularization protocols (Triton-X, freeze-thawing, and NaCl-SDS). Goat venous endothelial cells were isolated and seeded onto the acellularized xenograft leaflets. Microscopic examinations were done to select the most effective method of decellularizing xenogeneic cells and seeding autologous endothelial cells. Two pulmonic valve leaflets of. 6 goats were replaced by acellularized porcine leaflets with or without seeding autologous endothelial cells while on cardiopulmonary bypass. Goats were sacrificed electively at 6 hours, 1 day, 1 week, 1 month, 3 months, and 6. months after operation. Morphologic examinations were done to see the biological responses of replaced valve leaflets. Result: The microscopic examinations showed that porcine cells were almost completely removed in the leaflets treated with NaCl-SDS. The seeded endothelial cells were more evenly preserved in NaCl-SDS treatment. All 6 goats survived the operation without complications. The xeno- autografts and xenografts showed the appearance, the remodeling process, and the cellular functions of myofibroblasts, 1 day, 1 month, and 3 months after operation, respectively. They were compatible with the native pulmonary leaflet (control group) except for the increased cellularity at 6 months. The xenografts revealed the new endothelial cell lining at that time. Conclusion: Treatment with NaCl-SDS was most effective in obtaining decellularized xenografts and facilitate seeding autologous endothelial cells. The xenografts and xeno-autografts were repopulated with myofibroblasts and endothelial cells in situ serially. Both of grafts served as a matrix for a tissue engineered heart valve and developed into autologous tissue for 6 months.

As creativity is a crucial attribute for companies' survival and innovative success, many firms encourage and implement ways to promote employee creativity. Previous studies in the dual pathway to creativity model have shown that creativity can be enhanced when either the cognitive flexibility or cognitive persistence path is triggered. Although individuals have different personal traits, prior research has rarely investigated whether one pathway is more effective for a certain personality in promoting creativity than the other. Using attachment theory, we examined the influence of attachment style on the degree of the impact of each path on creativity. Specifically, we hypothesized that securely attached people would show higher creativity only when they use the cognitive flexibility path. Data from the US support our hypothesis. Our research highlights that the link between cognitive flexibility and creativity is salient when securely attached people use the cognitive flexibility path because of the strong fit between secure attachment and flexible thinking.
