구강암의 치료 후 생존율에 영향을 주는 인자에 대한 후향적 연구
조병호,민승기 원광대학교 치의학연구소 2002 圓光齒醫學 Vol.11 No.2
The objective of this research is to find out the influencing factors to recur oral cancers. The outcomes of 85 patients(male: 62 patients, female: 23 patients) with oral cancer who were not treated any pre-operative radiotherapy, chemotherapy or previous oral surgery, other than routine dento-alveolar procedures and a recent diagnostic biopsy were analysed retrospectively. Actuarial (life tables) survival analysis showed the 5 year survival rate was 58%, 52% for male patients, 72% for female patients. The patients who were under 50 years old showed 71% of 5 year survival rate, 51% of 5 year survival rate were above 51 years old group. Patients who were treated with elective neck dissection showed better prognosis which were shown 73% of 5 year survival rate than not neck dissection which were reveal 45% of 5 year survival rate. In TNM stage of patients, advanced stage showed worse prognosis, but only N stage did not suggest to judge good prognosis. Most patients were treated under postoperative radiation therapy and showed better prognosis.

A new method for the production of a disjoint products form of a fault tree output function is presented. It can be done by transforming a fault tree output function into a Binary Decision Diagram and failure rate can be directly calculated from it. The proposed method requires relatively fewer arithmetic operations in its evaluation.

Process modeling methods and process models were examined. A proposal of an Object-oriented Process Modeling Method which compensates the weakness of existing process modeling methods was presented. Also showed a practical way of establishing the project scheduling using this model. This model is to use a diagramming method showing activities and takes in the processes and interfaces between them after identifying processes, activities, tasks as objects. We contrived this modeling method to express the functional, behavioral, informational and organizational view of software processes by a single diagram and can express this using Ada by which we can check the consistency inside the model.

예혼합 압축착화 디젤엔진의 분사시기 변화에 따른 혼합기 형성 과정 및 연소 특성에 관한 연구
조병호,한용택,이기형,이창식,Cho, Byung-Ho,Han, Yong-Tak,Lee, Ki-Hyung,Lee, Chang-Sik 대한기계학회 2002 大韓機械學會論文集B Vol.26 No.12
A diesel engine has various merits such as high thermal-efficiency, superior fuel consumption and durability. Therefore the number of diesel engine in the world is increasing. As the seriousness of environmental pollution increases in the world, the method to reduce the noxious materials of $CO_2$, NOx and P.M. is very important subject to correspond to exhaust gas regulations. A new concept, so called premixed charge diesel combustion(PCCI), is focused among the various corresponding manners. In this study, we investigated the mixture formation within the cylinder with injection timing using GTT simulation code and also compared combustion characteristics of PCCI engine with that of commercial diesel engine. From this experiments, it could be found that homogeneous mixture formation was observed according to advance of injection timing and simultaneous reduction of NOx and Soot in injection timing of BTDC 60$^{\circ}$.

기업도 집단지성에 의한 지식 공유 및 외부와의 협력을 통한 지식의 생산/ 공유가 중요하다. 따라서 지식경영시스템도 SNS 기반으로 설계하고 구축한 차세대 지식경영 시스템 도입이 필요하다. 본 논문에서는 기존 지식경영 시스템을 조사분석하여 문제점을 분석하고 지식경영 패러다임의 변화와 새로운 지식경영 시스템의 요구사항을 알아보았다. 새로운 지식경영 시스템의 요구사항인 집단지성, 오픈이노베이션, IT 기술과의 융합을 고려하여 볼 때 차세대 KMS로는 SNS 기반 지식경영시스템이 가장 적합하다. 그러므로 새로운 차세대 지시경영시스템의 서비스 구조와 SNS 기반의 지식경영시스템의 메인 설계 및 지식톡 설계 등을 통하여 SNS 기반 지식경영시스템의 구축 방법을 제시하고자 한다. Knowledge sharing by collective intelligence, and knowledge production/sharing by outer cooperation is also important for the company. Therefore, it is needed the next generation KMS(Knowledge Management System) designed and built which based on SNS. In my paper, the problems of KMS are analyzed and new KMS's requirements and paradigm changes are examined by analysis of investigation of existing KMS. KMS based on SNS is appropriate for the next generation KMS in consideration of new KMS's requirements, that is, collective intelligence, open innovation, and convergence with IT technology. So a building method of KMS based on SNS is presented by new next generation KMS's architecture, main design and knowledge-talk design.

In a distributed computing system, it must have its tasks assigned among the processors so as to minimize the total of execution costs and interprocessor communication costs. Although there were many researches on tasks assignment problem, only special cases are considered, such as two processors, tree structure of interconnection pattern of tasks. Besides, most of them did not take constraints into account and ignored the time factor. In this paper, we assume that a task can only initiate invocations when it has completed execution, and present a generalized model including various constraints. In our model, time factor is considered and the costs of execution and interprocessor communication vary with time called phases. To solve this problem, we present. a Least-Cost branch and bound algorithm

소셜러닝은 미래 지식정보사회의 새로운 학습모델로 기존의 학습과 달리 개인의 능동성과 타인과의 협력학 습을 중시한다. 협력학습을 위한 소셜러닝 플랫폼 구축에 기존 소셜미디어 서비스를 활용하는 것이 유용하다. 본 논 문에서는 기존 소셜미디어 서비스 및 소셜플랫폼을 조사분석하여 소셜미디어 서비스를 활용한 효과적인 소셜러닝 플 랫폼을 제시하고자 한다. 또한 새로운 소셜러닝 플랫폼의 구조 및 설계화면을 통해 소셜러닝 플랫폼의 동작 방법과 다른 소셜 플랫폼에 비해 차이점과 우수성을 제시하고자 한다. Social learning is a new study model of future knowledge information society. In different existing study, it lay stress on individual activity and collaborative study with others. It is useful to apply social media services to build social learning platform for collaborative study. In my paper, after existing social media services and social platforms are investigated and analyzed, an effective social learning platform applyng social media services is presented. Also differences and superiority compared to other social platforms is presented through new social learning platform architecture and screen design.
