학습자와 학습객체간의 학습추론을 하기 위해서는 우선 학습자와 학습객체간의 연관성 정도를 파악해야 한다. 본 연구에서는 학습자가 전체 학습 중에 수강한 학습과 수강하지 않은 학습, 학습자가 수강한 학습을 전체 다른 학습자가 수강한 것과 수강하지 않는 정도, 학습자가 수강하지 않은 학습에 대한 전체 다른 학습자가 수강한 것과 수강하지 않는 정도를 가지고 2X2 메트릭스를 만들어 학습자와 학습객체간의 연관성 정도를 파악하여 이를 바탕으로 학습추론 시스템을 개발한다.

According to the rapid growth and popularization of the SMART device, the society is being changed greatly and importance of SW education is being emphasized. Also many student have a lot of interests about mobile application programming. The latest study suggests using the robots in the programming education may help to induce learners' interest and motivation, participation, achievement. So in this research, I designed a programming educational plan for SW education using robot and mobile application development tool(App Inventor) and applied them. And I conducted a survey four ares such as class, robot, App Inventor, robot and App Inventor. As a result, learner's response of interest and satisfaction was very positive commonly at four areas. In particular, learners could get programming result immediately using smart phone and could control the robot using smart phone, so learner's interest had increased especially. The conclusion is that suggested plan for SW education using robot and mobile application development tool is useful for programming education.

In this paper, we introduce the design method using CAE(Computer Aided Engineering) which is profitable in the compatibility and standardization of the developed product and in the reduction of construction time and price to develop and design a machine equipment. Particularly, we select the standard model to design ot develop from the large machinery to the super precision one, extract the peculiar characters of the model by the close analysis of the physical and technical part, can predict the previous result of experimental characteristics on objective dimensions through the analogical mathematical analysis, and can induce the design model demanded by user investigating optimal data in advance. We present the analogical algorithms and process method of design factors and restriction factors in the systematization design with computer. Then we analyze step functions for each systematization equipment and induce the process of technical data with actuator model.

1. 가시적인 PM(Product Model)의 구조와 자료구조의 미존재로 PM의 실체가 아직 개념적 수준에 머무르고 있다. 2. Physical통합 PM보다 Logical 통합 PM이 요구된다. 3. 광의의 PM 보다 협의의 PM개념에 의한 시스템 개발이 요구된다. :Step by Step 4. PM이 반드시 문제해결의 만병통치약은 아니다. 5. 설계.생산.관리의 각 부문별 고유특성을 살리고 무리한 단일 PM개발보다 Interface 가능을 갖는 중간자의 개발(경우에 따라서 직접 Access 할 수도 있음.) 을 통해 각 부문별 정보의 PM으로의 표현을 용이하게 하여야 한다. 6. 기존의 시스템, 개발중인 시스템, 개발예정 시스템등을 무리없이 순조롭게 통합하기 위해서는 현실적인 정보통합수단으로서의 PM 설계가 요구된다. 7. 생산현장의 각 공정별 자동화 설비 및 운용 소프트웨어, 이것으로부터 생성되는 각종 정보등을 관리할 수 있는 공정 별 생산정보시스템은 필수적으로 요구되는 시스템이다. 8. 자동화된 생산시스템에서의 PM과 생산현장의 POP(Point of Porduction)시스템과의 연계는 필수적이다.

The Airworthiness Certification from the government has an increasingly important role due to the dramatic growth of military aircraft development industry. It is a mandatory process of qualifying the flight safety within the aircraft's operational boundaries throughout its life cycle. The introduction of airworthiness certification has resulted in development paradigm shift from one requirement for one consumer need to the common requirement for many needs. This research paper provide the refinement of airworthiness certification criteria related to the flight control law and the verification methods which comply with its criteria.

The sludge oils were produced necessarily in the ships operation, so that it will be the best way to manage the sludge oils inside ship itself from a viewpoint of the prevention of marine oil pollution from ship. The ultrasonic breaking systems which recycle the sludge oil from ship into usable oil to be brunt is recognized as a most possible recycling device. In this regards, the purpose of this study is to examine erosion damage on the SS400 specimen by cavitation and the effect of impact pressure generated from the demolition of the cavity of ultrasonic vibration in the marine sludge oil environment .. The erosion damage of specimen was investigated mainly on weight loss, weight loss rate and maximum erosion rate with variation of the oil temperature as well as the change of space between transducer horn and specimen. The experimental results showed that as the space between ultrasonic vibrator horn and specimen disk increased, the weight loss and weight loss rate decreased and the values were larger in SFO than in SLO. The experimental results can be useful to the development of sludge oil disposing systems and to consider a countermeasure for the prevention of erosion damages by cavitation.

In the actual classroom the so-called flow learning is able to motivate the students through face-to-face feedback, and to meet their needs for educational achievement. By contrast, the so-called e-learning method falls short of the satisfactory level of real-life interaction, which makes many learners drop out or give up on their learning. In order to better the e-learning environment, this study presents a dialogue-based feedback system that improves the flow learning of the learners' in the classroom. This newly developed system was applied at the actual school. The result is that the experimented group improved its flow learning, compared with the controlled group. In the former group, each individual showed some consciousness of objective and challenge following the concrete feedback. That is to say, this system enhances the attitude of an active participation and induces the flow learning, thanks to the dialogue-based feedback and the sustained interest in learning. In conclusion, the significance of this study lies in suggesting the direction of a new learning method development in the e-learning environment.
