Globalization and multi-culturalizm have put light on the importance of cultural identity. To find or establish cultural identity designers have made their effort in their practice. Understanding possible expressional method for cultural identity in this context koreanity, can be a basis to promote such activities. The propose of this study is to investigate expressional method of koreanity in interior design cases appeared which were introduced in major domestic periodical publications since 1995. 43 cases were analyzed by using the analysis frame of 4 expressional method , such as an indicative imitation method, a partial invoked method, a partial transformation method and a conceptual reception method. As result 47％ of total cases were used the partial transformation method. 16％ by the indicative imitation method, 7％ by the partial invoked method and 30％ by the conceptual reception method. This result indicated designers have had more active attitude in expressing koreanity with interpretation of traditional concept in a contemporary way, rather than simply introducing and immitating traditional object. Design examples were organized and explained according to expressional method types.

Some conclusions can be derived form the study : 1) The script of Japan author's name for 3 years(1960-1962, not published by the National Assembly Library but by Korea Library Association)and that of 1963's was arranged by their mother tongue although they had not the "author index". 2) "Periodical's Index" which the publication of National Assembly Library was not accept the principle that the person's name should be pronounce and script by one's mother tongue. It means that the Library was not accept the uniqueness of personal name. 3) Because the arrangement of the same person's name is mixed with one's mother tongue pronunciation and Korean one that they are scattered each another. 4) The same surname and the same Chinese character has different arrangement because of pronunciation rule of Korean language. 5) The same person's name was regarded as a different one because of nonaccurate name transcription. 6) A Japanese name was transcribed as Hangul with Korean pronunciation. 7) A Japanese name was transcribed as Hangul with Korean pronunciation and added Chinese Character in parenthesis. 8) A same Japanese name was regarded as a different one when it was transcribed with Chinese character and Hangul. 9) The arrangement of a same person's name was different when between the surname and forename has one space and has not. 10) "Author Index" is not playing as a role of name authority file.a role of name authority file.

The objective of this study is securement of upland irrigation water using storage level management of small dams. However, it is not new development of water resources but securement of water using storage level management of existing dam. This study has enhanced the water utilization coefficient of dam, after extra available water had been calculated by application of periodical management storage level and this water is used to other water like the upland irrigation water demand. As the result of application, it can secure extra available water except the water requirement. Minimum extra available water except flood is about $20,000,000\;m^3$ and crop irrigation water demand of 10yr frequency is about $2,033,000\;m^3$ in Seongju. The utilization of crop irrigation water can be possible. And extra available water is about $3,102,000\;m^3$ in 2000, $1,959,000\;m^3$ in 2001 except flood period and crop irrigation water demand of 10yr frequency is about $2,272,000\;m^3$ in Donghwa. It is judged that extra available water cannot be used to crop irrigation water during the dry season in Dongwha. Consequently, when management storage level is determined and more efficient use of water is gotten like this study, water utilization coefficient will be enhanced.

In Korea, upland irrigation generally depends on the ground water or natural rainfall since irrigation water supplied from dams is mainly used for paddy irrigation, and only limited amount of irrigation water is supplied to the upland area. For the stable security of upland irrigation water, storage level of irrigation dams was simulated by the periods. A year was divided into 4 periods considering the irrigation characteristics. Through the periodical management of storage level, water utilization efficiency in irrigation dams could be enhanced and it makes available to secure extra available water from existing dams without new development of water resources. Two study areas, Seongju and Donghwa dam, were selected for this study. Runoff from the watersheds was simulated by the modified tank model and the irrigation water to upland crops was calculated by the Penman-Monteith method. The analyzed results showed that relatively sufficient extra available water could be secured for the main upland crops in Seongju area. In case of Donghwa area, water supply to non-irrigated upland was possible in normal years but extra water was necessary in drought years such as 1998 and 2001.

This study was about the fashion model's images during the periods of time. Also, this was to know the model's role and fields they had worked in and to investigate the specializing courses to get advice from their diversities, specialties and activities. The method of the study was used the qualitative analysis from the relative books, theses from university graduates, the related society newsletters, fashion magazines that were printed periodical/non-periodical, and others. As a result, the glamourous image was the most famous in the twenties and thirties, and the elegant image mainly in the forties and fifths. The images were more diverse in the nineties through the girlish images of the sixties, and the sexy image with good health of the seventies and eighties. Baby faces became the ideal of models in the new century. The images of the models become popular and disappear rapidly due to the change of major trend with the change of the society's environment. Under the situation, they must take good care of their images and self-control themselves to keep a positive view of fashion models to the public, and they must have ambition as a fashion icon and make their own exclusive fields in various parts.

The purpose of this study is exploring the expressional characteristics of organic fashion design different from the past by analyzing the expressional characteristics of organic fashion design dependent on the digital paradigm and simultaneously suggesting the theoretical data required to understand the changing trend of organic design in relation to the paradigm of the age. The results of the research is as follows; The expressional characteristics of organic fashion design according to the digital age appeared to have same aspects. Pluralism respecting multi-culture, hybrid of multi-meaning image, circulation that can consistently circulated, non-hierarchical post-structure, de-boundary through dissolution of genres, digital nomad considering mobility, human centered through significant sensitivity, de-materialization of assimilation between reality and non-reality, conceptualization given the concept of designer, technology combining with digital technology. This study found that organic fashion design in the digital age has the same conceptual context as periodical paradigm freely circulating consistently by organically combining each individual. This can be understood as the trend of design implied in conceptual context that organic fashion design requires periodical paradigm.

The attitude control of a double inverted pendulum with a periodical disturbance at link top is dealt in this paper. The proposed system is consisted of the double inverted pendulum and a disturbing link; a triple inverted pendulum with two motors. The lower link is hinged on the plate to free for rotation in the vertical plane. The upper link is connected to the lower link through a DC motor. The DC motor is used to control the posture of the pendulum by adjusting the position of the upper link. The periodical disturbance can be generated by the additional like attached at the end of link 2 through another DC motor, which is the modeling of a posture for a biped supporting with one leg. The motor for the joint simulates the knee joint(or hip joint) and the disturbance for the legs moving in air. The algorithm for controlling the proposed inverted pendulum which is regarded as a virtual double inverted pendulum with a periodic disturbance, is consisted of a state feedback control and a fuzzy logic controller connected in parallel. The fuzzy controller keeps the center of gravity of the biped within the specified range through the nonlinear feedback compensator. The state feedback control takes over the role to maintain a desired posture regardless the disturbance at the link top. Simulations with a mathematical model and experiments are conducted to show the validity of the proposed controller.

In e-Trade, Real-Time System(RTS) plays a very important role. Each task is set with limited time, and appointed regulations must be followed because it can be greatly damaged if it cannot be executed in limited time. In e-Trade, the scheduling possibility techniques generally use periodical tasks; however, it is necessary to study more stable prediction scheduling possibility algorithm by using other task timing conditions and non-periodical task scheduling tasks. This study proposed an algorithm to increase the prediction possibility using individual task utilization rate, and presented scheduling possibility conditions using existing whole task utilization rate and the proposed algorithm.
