Visual Basic 을 이용한 비선형방정식의 수치해법 교육프로그램에 관하여
이규봉 한국수학교육학회 1999 수학교육논문집 Vol.8 No.-
수학을 교육하다 보면 느끼는 것 중의 하나가 학생의 이해를 돕기 위하여 수학 내용을 시각적으로 알려주되 그 방법이 쉬운 것을 찾는 것이다. 컴퓨터의 발달과 보급으로 인하여 조그만 노력하면 이것이 가능하다는 것을 보여준다. Visual Basic은 윈도우 컴퓨터 언어로서 배우기가 쉬울 뿐 아니라, 이 언어를 이용하여 윈도우용 실행화일을 쉽게 만들 수 있다. 이번 발표는 수치해석학에서 비선형방정식의 해를 구하는 과정을 그래픽을 이용하여 보여주는 프로그램 작성에 관한 것이다. 이것은 모든 수학의 주제에 이용할 수 있다는 가능성을 보여준다. 또한 이것의 종합적인 개발로 수학 교육에 관한 프로그램을 개발할 수 있다.

Analysis of Energy Efficiency in PCB Manufacturing Process

Recently, development of renewable energy and improvement of energy efficiency become important issues due to high oil price and global warming. The improvement of energy efficiency restrains the growth rate of energy demand to result in delaying or reducing the expansion of energy supply facilities. As most of energy consumption occurs in industries, it is natural that various methods are sought for energy savings through an efficient management of energy resources consumed in shop floors of industries. In this paper the Energy Resource Management (ERM) system is proposed efficiently to manage and analyze energy consumption and CO2 emission in industries. Data of energy consumption are measured in real time by means of electric power meters and stored in the ERM system by using Machine-to-Machine (M2M) devices. Energy efficiency of a manufacturing process is analyzed based on the data. In this paper the system is implemented in the inner scrubbing process and drilling process for manufacturing PCB and the reflow soldering process for surface mounting of chips or devices on PCB. The results obtained from the implementation are analyzed and reviewed to check usefulness and reliability of the ERM system. The ERM system proposed in this paper mainly for monitoring and analysis of energy consumption can be utilized as the guidelines to manage and improve the energy efficiency in manufacturing processes.

Angiosarcomas are rare, but aggressive malignancies. Reports of brain metastasis are uncommon. In this report, we describe the clinical features of a 62 year-old man who presented with hemoptysis and right-sided weakness. Chest computed tomography showed multiple ill-defined part solid nodules in both lungs and brain magnetic resonance imaging showed multiple hemorrhagic bran masses. The patient underwent whole body proton emission tomography to identify biopsy site and showed multiple bone lesions. A right acetabulum biopsy in confirmed the diagnosis of angiosarcoma.

This study is aimed for grasping scenic characteristics of sloping-land high-rise apartment complex in visual-sensory ways as the pre-stage for the purpose of preservation and improvement of metropolitan scenery. The building which is located on slopping-land has three-dimensional properties compared with that which is located on flatland, and has great influence to metropolitan scenery with viewpoint verticality and geographical characteristics. It's also changed as sight-distance changed. The vast high-rise apartment complex is comprised set of buildings. It's required to examine closely that how architectural elements of each unit building are changed as location and distance of viewpoint is changed in visual-sensory ways and that main component factors of complex scenery are. Setting the metropolitan scene sight from stationery viewpoint, we described and quantitively analysed changing phase of the component factors of complex scenery, that is, complex shape as sight-distance (near, middle-range, distant), viewpoint height, and slopping degree of ground are changed on slopping-land high-rise apartment. And enlighting the visual-sensory important factors which constitute slopping-land high-rise apartment complex scenery, we grasp visual-sensory scenery characteries of slopping land.
