The dream of futurists andtechnologists is to build complex, multifunctional machines so small that theycan only be seen with the aid of a microscope. The unprecedented technologyadvancements in miniaturizing integrated circuits on semiconductors, and theresulting plethora of sophisticated, low cost electronic devices demonstratethe impact that micro/nano scale engineering can have when applied only to thearea of electrical and computer engineering. Emerging research efforts indeveloping organic and inorganic nano materials together with using micro/nanofabrication techniques for implementing integrated multifunctional devices hopeto yield similar revolutions in other engineering fields. By cross linking theindividual engineering fields through micro/nano technology, various organicand inorganic materials and miniaturized system devices can be developed thatwill have future impacts in the IT and life science applications. Yet to buildthe complex micromachines and nanomachine of the future, engineering will needto develop the technology capable of seamlessly integrating these materials andsubsystems together at the micro and nano scales. The micromachines of thefuture will be “integrated nanosystems,” complex devices requiring the integration of multiple materials,phenomena, technologies, and functions at the same platform. To develop thistechnology will require great efforts in materials science and engineering, infundamental and applied sciences. In this talk, we will first discuss thenature of micro and nanotechnology research for IT and life sciences, and thenintroduce selected current activities in micro and nanotechnology research fororganic and inorganic materials and devices. The newly developed micro/nanofabrication processes and devices, combined with in-depth scientificunderstandings of materials, can lead to rapid development of next generationsystems for applications in IT and life sciences.

The purposes of this study are two folds: a) to introduce conjoint choice model to research the choice behavior of theme park users, and b) to suggest the strategies to strengthen the competitiveness of theme parks. The major four theme parks in Seoul metropolitan areas were selected as study areas. A leading polling agency was employed to select 432 respondents by probability sampling and to conduct face-to-face interview. Both alternative generating and choice set generating fractional factorial design were conducted simultaneously to meet the necessary and sufficient conditions for calibration of the conjoint choice model. Dummy coding was used to represent the attribute levels, and the alternative-specific model was calibrated. The goodness-of-fit of the model was quite satisfactory($\rho$$^2$=0.47950), and most parameters values had to expected sign and magnitude. Car was preferred transport mode to shuttle bus for visiting theme parks ; however the most ideal attribute levels only were estimated significantly. Most attribute levels of shuttle bus were estimated significantly except the Dream Land, which is the least attractive park among study areas. Simulation results showed that the shuttle bus was a mode worth providing to switch the current car dominant visiting pattern of theme parks, which will be one the effective strategies to attract more patrons, especially for potential users adjacent to parks. Several ideals were suggested for future researches, in terms of utilization of more general utility function and new base alternative, and inclusion of more salient attributes such as constraints in the model.

This study investigates the effect of a leadership program to enhance leadership skills in children from low-income families. A total of 45 elementary school students participated in the 52-week leadership program. Five leadership scales, such as goal attainment, paradigm shifting skills, skills to lead others, human relationship skills, and sense of purpose, were measured through survey questionnaires before and after implementing the program. In addition, individual teacher interviews examined the influence of the program on students' leadership skills. This study found that participants showed significant improvement after implementing the program in the three domains of the leadership skills (goal attainment, paradigm shifting skills, and human relationship skills); however, the skills to lead others and sense of purpose did not significantly change. The leadership teachers also stated that the program influenced positively on students' leadership skills; in addition, students' behavioral changes were found by developing relationships with other children as well as contemplating and attempting to find a future dream and vision. The leadership program was effective to enhance leadership skills in children from low-income families. This study can provide the theoretical and practical foundations for the development and implementation of effective leadership programs that meet the needs of children from low-income families.

Recently, pirates are infesting on the sea and they have been hijacking the several vessels for example Samho Dream and Samho Jewelry of Korea. One of the items to reduce the risk is to adopt the invader detection system. If the pirates break in to the ship, the detection system can monitor the pirates and then call the security alarm. The crew can gain time to hide to the safe room and the report can be automatically sent to the control room to cope with the situation. For the invader detection, an unmanned observation system was proposed using the image detection algorithm that extracts the invader image from the recording image. To detect the motion area, the difference value was calculated between the current image and the prior image of the invader, and the 'AND' operator was used in calculated image and edge line. The image noise was reduced based on the morphology operation and then the image was transformed into morphological information. Finally, a neural network model was applied to recognize the invader. In the experimental results, it was confirmed that the proposed approach can improve the performance of the recognition in the invader monitoring system.

The hand is a frequently affected area in high voltage electrical burn injury as an input or output sites. Therefore, early debridement and synchronous flap coverage are generally accepted as a primary treatment of several electrical burns complicated by exposure of tendons, neurovascular structures, and bones. So, in order to establish convenient, promising methods for the reconstruction of hand defects in electrical burn patients, we performed various reverse forearm flaps. From March 1997 to February 2000, we reconstructed 12 cases of hand defects in high voltage electrical burn wounds with reverse forearm flaps. Reverse radial fasciocutaneous flap were 3 cases, reverse ulnar fasciocutaneous flap were 3 cases, reverse ulnar fasciocutaneous flap and STSG were 4 cases, reverse ulnar fascial flap and STSG were 2 cases. We successfully reconstructed hand defects in all 12 cases, and obtained following conclusions. 1 Various reverse forearm flaps provide well vascularized, profitable tissues and they require short operative time with relatively easy procedures. 2. Reverse fascial flap and STSG, reverse fasciocutaneous flap and STSG provide thin flaps with good aesthetics and minor donor site morbidity.

Clothing color for animation characters is very important in expressing a given characters image and characteristics. Consequently, in this paper, we propose a tool that allows an easy and simple selection of clothing color combinations in conjunction with previous color combination image research (color image chart). This tool has two functions, The first allows the user to search what color best fits a given image, and the second calculates which image is closest to the color that user has chosen. This tool was developed so it can be used over the web, and was used to verify whether the color combination for Disney and Dream Works animated characters' clothing has been selected appropriately according to the character's image, as determined through a survey.

This is a study on the roles in the association of sound as subtext for animation. On this study, it will be helpful to develop sound concepts and to create animations with creativity. For animation without sound can be produced as an artistic purpose, however, most animations are created with sound. It is not means that sound is less important than visual in animations. Sound is also one of significant element to create animations. Sound have many important rolls for subtext such as parts of action, leitmotif, characteristic, time, ethnic, localization in the animations. It will be analyzed two animations such as Shrek (DreamWorks Pictures production/ Director: Andrew Adams) and Monsters Inc. (Walt Disney Pictures/ Director: Peter Doctor).

This study aims to understand the meaning that learning of the old age has, through old age learners who augustly live after retirement-life so called successful silver years. Qualitative research methods is used for analyzing the contents of articles about 15 old age learners and the results are follows below. First, the retirement has dual meaning for the old learners. One is they experienced psychological and emotional insecurity after retirement and the other is it is a turning point for them to realize their longtime dream. Second, the old age learners showed enthusiasm about learning and they voluntarily found the way of success in their silver years. Finally, the old age learners working in new career with provocative and enthusiastic attitude work as a role model of successful old age life and show how they progress. This study argued that we need to consider the old as active agents and the old age as the time when productive and continuous learning can be done. In addition, this study strongly insisted that we need to realize the importance of 'education by the elderly' and social and other relevant conditions are needed to be established immediately.
