In this paper, we optimized the PDT laser system to improve the therapy effects of malignancies. In order to optimize, the variation of laser output and specific wavelength shift have to reduced. To improve the PDT therapy clinician require the diverse radiation mode which irradiate the tumor surface. Continuous wave mode that general application may causes tissue thermal damage not only to tumor tissue, but also to normal tissue. In this paper, therefore, we suggested new technique for radiation method to improved PDT effects and prevented to the thermal effects for the tissue. In the experimental we verified the stability of wavelength, laser output stability and proved the reduced thermal effects to the tissue using the pulse & burst radiation modes in vitro.

Previous literatures have provided growing evidence regarding the impact of leadership in enhancing follower creativity. Despite these ample evidences, a noticeable omission in this body of study is entrepreneurial leadership. The present study extends leadership·creativity research by developing a mediation-moderation model and investigating the key roles that innovation climate and psychological empowerment may play in the mechanism between entrepreneurial leadership and followers' individual creativity. Using a data of 161 SME's members, the results show that: (a) followers' psychological empowerment positively mediates the relationship between entrepreneurial leadership and individual creativity; (b) the impact of entrepreneurial leadership on followers' psychological empowerment through innovation climate is high (in other words, innovation climate positively moderates the relationship between entrepreneurial leadership and followers' psychological empowerment). This study gain more comprehensive insight of individual creativity and leader's entrepreneurial leadership, to foster more creative venture organizations. The findings of this study make several important implications to present venture·leadership·creativity knowledge. Future studies should examine a broad range of mediating or moderating processes through which context for innovation effects positively on individual creativity. Therefore, additional study is needed to test if the results of this research can be generalized across industry·firm types.

최근 사회의 다양성과 기업환경의 변화, 정보기술(IT)의 발달로 조직운영의 생산성 및 효율성 제고와 대고객 서비스 수준향상을 위해 업무처리를 자동화 시키고자 하는데 많은 관심을 가지게 되었다. 현재는 누가 무슨일을 하고 있는지 파악이 어렵고, 조직에 의해 정의된 룰과 시스템에 따르기 보다는 개인의 주관과 판단에 따른 업무 수행이 되고, 무엇보다 변화하는 시장환경에 유연하게 대응하는데 어려움이 많다. BPM(Business Process Management)은 조직내의 사람과 시스템, 어플리케이션을 통합하는 개념으로서 워크플로우와 응용프로그램통합기술(EAI)이 결합된 시스템으로 업무의 자동화는 물론 모니터링, 평가등을 통하여 획기적으로 ROI를 개선해 주며 적용을 위해서는 프로세스와 시스템을 아우러는 컨설팅과 구현이 따른다. 그러나 BPM의 개념적 만족은 하지만 초기단계로서 적용사례가 부족하여, 적용하기 위한 의사결정은 쉽지 않다. 본 논문은 BPM의 개념파악과 BPR, 워크플로우와 BPM의 차이점을 비교분석 하고, 대규모 대량의 트랜잭션과 수천명의 사용자 및 다수의 비즈니스 어플리케이션이 관여하는 금융여신 프로세스에 BPM을 적용하는 사례를 제시하고자 한다.

정보화부문에 대한 투자가 지속적으로 증가하고 있다. 그에 따라 투자한 데 대한 평가에 대한 수요도 급증하고 있다. 평가는 사업추진에 대한 책무성을 높이고 투자대비효과에 대한 검증과정으로서 정부부문에서는 필수적이다. 평가는 그 목적이나 활용에 따라 다양한 시각에서 주체가 다양할 수 있다. 그 어떤 정부기능도 배타적일 수는 없고 오히려 기능간에 어느정도의 중복성은 서로 다른 정책적 지향성을 갖는 현재의 정부조직의 편제에 비추어볼 때 평가도 다양한 시각에서 시행될 수 있다. 그러나 현재 정보화부문에 대한 평가는 지나치게 그 주체가 다기화되어 있고 다양한 주체가 시행하는 평가임에도 불구하고, 그 차별화는 명확하지 않아 평가중복에 대한 불만이 팽배하고 있다는 점이 문제이다. 뿐만 아니라 최근 국내외적으로 관심이 고조되고 있는 성과관리의 개념을 평가 제도가 갖는 한계를 극복하기 위한 방안으로 어떻게 도입할 것인가에 대한 방안 모색이 시급하다. 이 연구는 이러한 취지에서 현재의 정보화부문에 대한 평가제도를 고찰하고 문제점을 도출하여 정보화투자의 실효성을 높이기 위한 평가체계 및 제도화 방안은 무엇인지 그 방향을 제시하는 데 그 목적이 있다.

Purpose: The recent development of MR has made to possible radiological diagnosis in various soft tssue tumors. But multifarious components within soft tissue tumors and their periodic change have made to difficult even differentiation of malignant from benign soft tissue tumors solely on the MR. So authors retry to differentiate malignant from benign soft tissue tumors with clinical and MR finding complex. Materials and methods: We were analysed 82 pathologically confirmed soft tissue solid tumors (37 cases as malignancy including intermediate tumors and 45 cases as benign including inflammatory masses) which are correlated with clinical findings such as age, size, and location, MR findings such as tumor border, texture on T2 and contrast-T1 images, and enhancement area retrospectively. Many typical lipoma and cysts including of ganglion and abscess are rejected in the benign soft tissue tumor group because not difficult to diagnose on MR. Results: Malignant soft tissue tumors were more frequent in 21~40 and 61~80 years old of the age, above 3.0 cm of the size, trunk-pelvis-lower extremities of the location, and MR findings with irregular border and above 50% of the enhancement area than those of benign soft tissue tumors. Conclusion: The clinical finding that divided to two locations as trunk-pelvis-lower extremities and upper extremities-shoulder-spine was statistically significant to differentiate malignant from benign soft tissue solid tumors. However, the others would provide some useful informations to differentiate them never specific.

전통적인 애플리케이션 서비스 영역이 수술대에 올랐다. 그동안 IT 관리자들은 애플리케이션을 조직내에 구현하기 위해 많은 고통을 겪어 왔다. 솔루션을 인스톨하는 데에 지나치게 많은 비용이 요구되며, 구현하기 위해 상당한 작업량이 요구된 것이 사실이다.결국 관리자들의 실제 조직에 효율성을 부과하기 위해 총력을 기울이기 보다는 애플리케이션을 설치하고 관리하는 비교적 초보적인 작업에 모든 시간을 할당해야만 했던 것이다. 하지만 이제 그러한 고충도 과거의 씁쓸한 얘기로 지워질 날이 멀지 않았다. ASP가 부각되면서 애플리케이션 호스트 서비스가 본격화되고 있기 때문이다. 이미 호스트 애플리케이션은 다양한 형태로 진화하고 있는데, 업계에서는 10년 이내에 기업 애플리케이션의 80%이상이 이러한 서비스를 이용하게 될 것이라고 전망하고 있다.
