This research is to identify an easy and effective method of teaching-learning plan. The teaching-learning plan is a blue_print applied for designing effective lessons. However, most of the teachers regard it as a difficult and inefficient job. This study proposed the concrete instructional model framework as a tool to develop the teaching-learning plan easily and effectively. The concrete instructional model framework will represent a decomposed instructional strategy applied for each step of the instructional model developed by educational researchers. This method is applied to develop a computer teaching-learning plan. Therefore, the proposed method will expand an easier teaching-learning plan. Furthermore, the proposed method develops a teaching-learning plan with fluent content in detail based on low-level instruction strategies applied in the concrete instruction model framework.

Jini, UPnP, HAVI와 같은 홈 네트워크에 필요한 미들웨어 기술들을 데스크 탑 환경뿐만 아니라 모바일 환경에서도 동일한 서비스를 이용하고자 하는 사용자들의 요구가 증가하고 있다. 이 중 Jini 접속기술을 적용한 디바이스는 응용 서비스와 직접 의사소통을 할 수 있고, 서비스 이용에 필요한 설정의 번거로움 없이 편리하게 이용할 수 있다. 그러나 Jini 접속기술은 데스크 탑 환경을 중심으로 설계되어 있으므로 휴대폰과 PDA와 같은 모바일 디바이스에서 Jini 접속기술을 사용하기에는 많은 제약이 따른다. 본 논문에서는 이러한 점을 고려하여 Jini 접속기술을 직접 적용하기 어려운 소형 컴퓨팅 디바이스에 적합하도록 기존 Java 실행 환경의 클래스들을 이용하여, 그 응용 모델로써 모바일 디바이스를 위한 Mail Service와 Print Service 시스템을 설계 및 구현한다.

Full-scale ferro-concrete building technology came was introduced in Japan in Meiji $35{\sim}40(1902{\sim}1907)$ and heralding the beginning of urban modernization. On the roofs of these new architectural constructions, full-scale rooftop gardens were also developed. We consider that gardens established on the roofs of hotel and department stores created a new, modernized garden culture, which greatly influenced the early modern urban culture of Japan, the drama of which it conceived based on the impression in a rooftop garden is made. In this paper, we discuss the influence of Meiji-Era cultural and technological advances on rooftop gardens constructed during the Taisho $Era(1912{\sim}1926)$, as represented by the gardens of Kobe's Oriental Hotel, Tokyo's Mitsukoshi Department Store and Shimonoseki City's Akita Company. Photographic and print sources are utilized to analyze the design features and temporal changes of these pioneering rooftop gardens, as well as their influence on urban culture.

As an effort to reduce cost and lead-time and to increase flexibility and responsiveness, manufacturers are using digital printing in numerous process steps. Typically, these processes require the precise dispensing of various fluids. Piezo ink jet printheads are proving to be reliable tools for depositing active materials such as light emitting polymers (LEP) for mobile phone displays and color filter inks for liquid crystal displays. Ink jets are also being used to provide uniform coatings of polyimide alignment layers and spacers for LCDs. Success with legend printing on PCBs using ink jets has encouraged the design of equipment for directly printing both etch resist and solder mask for PCBs. Development of printers for passive components such as capacitors and resistors is underway. This paper will present the attributes of an ink jet printhead designed to a precision deposition tool and discuss how it is being used to digitally print electronic and flat panel display components. Status of commercialization of digital printing will be discussed along with issues to be resolved before wide adoption takes place.

The word 'chintz' is thought to be a corruption of spotted cloth. Printing remained a relatively primitive method of decorating textiles in Europe until the second half of the 17th century. The formation of the English East India Company sparked the influx into the West of painted and printed Indian cotton textiles. A William Sherwin took out the first English patent in 1676. The earlist European designs were florals in the Indian manner. Patterns of European flowers returned to England as birds, flowers, trees, vines and stained glass for Victorian chintz. In France, the original and most successsful manufacturer of the distinctive printed fabrics from Jouy was Christophe Philippe Oberkampf. Copperplate printing was introduced to Jouy in 1770, probably reaching the pinnacle of achievement in the craft after 1783 when Jean-Baptiste Huet became chief designer. Huet's style was widely imitated in France and abroad, and the term 'toile de Jouy' has come to be universally applied to monochrome figurative designs wherever and by whomsoever they were produced. Oberkampf served his apprenticeship as an engraver with some leading manufacturers, including a period in Mulhouse. In Alsace, which was not part of France until 1798, the first factory had opened in 1746 in Mulhouse, and the area soon had the largest number of print-works in France.

A focal length-correcting lens called the F-theta lens is required to compensate for the different focus on spot size due to the deflected incident laser beam. The F-theta lens was designed by the ray tracing method and fabricated by a 3D printer with polymer-based material. The designed F-theta lens is able to compensate for the focus on spot size by an incidence angle of 0 to 2 degrees. Based on the analysis of the simulation, there was almost no aberration in the $0^{\circ}C$ incidence angle, and the maximum of $50{\mu}m$ of aberration was observed at the incidence angle of $2^{\circ}$. Diffraction-encircled energy was analyzed to characterize the designed optics, and an image simulation was performed to confirm the actual image resolution.

The fabrication of a focal length-correcting lens called the F-theta lens was performed by a 3D printer. The fabricated lenses were characterized by transmittance and reflectance measurements. The optical properties of the lens, such as scattering or transmittance efficiency, were analyzed with respect to the wavelength (red, green, and blue) and the surface roughness of the lens. There was almost no shape aberration on the focus location of 0 degrees, but elliptical focus shapes were found at 1 and 2 degrees of the laser incidence angle. The developed process is expected to be used for the quick fabrication of lenses with low costs and quick turn-out. By improving the surface roughness during postprocessing, the optical properties are expected to be comparable to commercial lens quality.

In this paper, we present a design, analysis, fabrication and performance test of the novel DoD metal-jet system for application to the high-density and high-temperature-melting materials. The theoretical analysis of the metal-jet nozzle system is derived by using electro-mechanical analogy. Based on the theoretical analysis results, we design the metal-jet print head system and fabricate the metal-jet system, which can eject the droplet of lead-free metal solder in high-temperature. In the experimental test, we set up the test apparatus for visualization of the droplet ejection and measure the ejected droplet volume and velocity. As a result, the diameter, volume and the velocity of the ejected droplet are about 65 $\mu$m $\sim$ 70 $\mu$m, 145p1 $\sim$ 180 pl and 4m/s, which shows quite good agreement with the theoretical analysis results of the 75 $\mu$m-diameter and 220 pl-volume of droplet. In comparison with the experimental result, the errors of diameter and volume are 7% $\sim$ 13% and 18 $\sim$ 34%, respectively.

Surrealism's method of expression and inspiration has been a continuous influence on fashion. What is important is how to identify and research a source of inspiration, and how to use this inspiration to guide the designs that can be worn on a real human body. Therefore, the purpose of this study was to show how to develop ideas and designs from Surrealist objects and how to contribute to the development of designs to the diversity in visual and functional effects along with the changes in consumer's interest. Documentary studies about Surrealism and Surrealist-inflected fashion applying the works of Surrealist and fashion images as a tool of historical research were proceeded. And the ideas for theme, the motifs for print patterns, and the concept of designs were borrowed from Surrealist objects touching on the imagery between the real and reflected, optical and artificial, and the designs were developed with several different visual and functional effects changing color, pattern, size, and length with the function of zippers in each item. It also gives the person wearing it amusement because it includes the concept of play and D.I.Y. With effective planning, it is possible to attract consumer's interest in the market.
