The purpose of this study is to point out that the segment-based study on child phonological acquisition is not sufficient in accounting for the ever-changing dynamic development of child phonology and to attempt to explain child phonology in terms of syllable-based theory of phonology, one of various types of non -linear phonology which have been studied since the late 1970's. According to Gruber's observation. it is obvious that children perceive their own concept of syllable even at the early stage of babbling. In addition, the statistical data show that the CV-type syllable is most frequently used in child phonology. These evidences seem to suffice to conclude that the CV-type syllable is the most unmarked of all four core syllable types in the sense of Clements & Keyser(1983). Starting with this observation, it is further argued that in child phonology the markedness of syllable types increases in the order of CV, CVC, VC and V.

The development of the solar and the wind power energy is necessary since the future alternative energies should have no pollution and no limitation. currently power generation system of MW scale has been developed, but it still has a few faults that its operation depends on with the weather condition. In order to solve these existing problems. combined generation system of photovoltaic(400W) and wind power generation system(400W) was suggested. It combines wind power and solar energy to have the supporting effect from each other. However. since the combined generation system cannot always generate stable output with ever-changing weather condition, power compensation device that uses elastic energy of spiral spring was added. In an experiment. when output of system gets lower than 12V(charging voltage), additional power was from the stored rotational energy of spiral spring.

The paper examined effect of age cohort on life cycle financial planning. A total of 990 questionnaires were distributed with a 55.2% return rate. Seven hypotheses were analysed using hierarchical and ordinary regression analysis. The results revealed that age cohort variables made significant contribution to life cycle financial planning as well as personal orientation towards retirement planning, particularly the younger age cohort. Age cohorts do affect personal orientation towards retirement planning with the confidence level making a significant impact. Current financial resources do have a strong positive impact on consumption for all age cohorts. On the other hand, no significant effect was found between age cohorts and current financial resources but older age cohorts were relatively more significant predictors. The implication was that not only should their individual perceptions of financial planning become an increasingly important part of people's long-term commitment throughout their life-cycle, it must also assume the role as a self-directed life-long learning process, in view of the ever-changing and complicated financial environment.

Schools have focused so far on a student-oriented education. As the roles of schools, however, have been increasingly emphasized in the information society, community-centered functions are now additionally required. Beyond simply allowing communities to utilize selected facilities, schools can conduct re-education programs for community residents and actively use their facilities for such purposes. As explained above, schools must continuously evolve to meet current needs and demands, such as by offering special classes and utilizing learning facilities in the elementary levels to promote learning in ever-changing societies. This study analyzed the functions of school facilities to communities, as well as the educational functions involved in teaching-learning processes, in light of the advent of a knowledge and information society. Through analysis, the types of information facilities in elementary schools were derived. On the basis of such derived types, systematic and reasonable methods to estimate the scope were suggested.

The purpose of this study was to analyze the features of the avant-garde architecture in the end of the 20th Century based on the ontology as a metalanguage. In view of the results so for achieved, it is possible to say that the thought of becoming, topology, rhizome thought and the Deleuze's concepts of the fold and the event as ever-changing and evolving at any given time are found in the avant-garde architecture, and the introduction of ontological thought into architectural design encourage hopes for a more natural and existential quality in architecture. However, the avant-garde architecture in the end of the 20th century disclosed the limitation in the architectural expression of ontological thought due to the lack of fully understand on ontology. In conclusion, the ontological approach in architecture offers a new morphological methodology and a new way of programming considering the existential aspect of space through the bricoleur's means leaving the ontological meaning of architecture itself.

Ever since the local interior and architecture design industry adopted Digital fabrication modeling tool for its design operation in early 1990's, working environment has been changing. The Purpose of study is to analyze the digital Architecture fabrication modeling for digital design education in academy course. Digital Design Tools, Digital Space and Form, Digital Materiality and Digital Production. The Digital fabrication modeling is and important role in a traditional design process and digital design process. It is comprised of digital input devices(3D digitizer, 3D design tools) and digital output devices(cutting plotters, laser cut, CNC machines, 3D printers). Digital input devices can be shift a traditional design process to digital design process. Digital output devices are the principle of digital fabrication by CAD/CAM. Also, the result of this study provide the fundamental data for physical resources and digital design curriculum in KAAB.

To improve usability and recognition of product, the term, Affordance, started to be known in the design world by US recognitive psychologist, Donald A. Norman, has the meaning of providing, Act inducement, Act motivation, Expectancy or what environment provides, etc., thus as one of Mental Model, providing ever more importance not only to the everyday life goods but to the time like these days when products for information overflow. Particularly, this study is oriented toward providing basic study framework on Affordance-like approach in pursuing psychological approach in design for changing the limitless phenomena involved in environment and human body and further for inquiring into source of idea from abstract form hint latent in act and further from the act conducted everyday while peoples are unconscious.

Discussing the history of mathematics in classrooms is often recommended as a way to help show that mathematics was not handed down unchanged from God into the students' notebooks but has been changing and growing throughout the centuries. Now that new millenium century is begun, it is appropriate for historians to look back and for teachers to show that mathematics is not only alive and well but in its most productive period ever. This paper is a brief summary that hints at the flavor of recent mathematical developments. Even if the actual content may be difficult, however, the exciting stories of the people, developments, results, and applications deserve coverage. These stories can add life to school mathematics and encourage our students to join in the fun.
