The purpose of part I of this research was to study the definition of the wearable computer, the influential factors which led to its advent, the history of its progress and to prospect the figure of future research in fashion field of it. A qualitative analysis was applied to fulfill the research purpose, in which academic reports, professional journals, newspapers, magazines, books and sites were reviewed and analyzed in depth. The wearable computer which has been developed as a type of the portable hardware for computing during the first period, 1960s-1980s, has progressed into apparently softer and technologically advanced prototypes during the 2nd period, early-mid 1990s. From the beginning of the 3rd period since late 1990s, 'really wearable' prototypes were developed as the results of efforts to invent the more comfortable and interactive 'wearcomp' Based on the result of the analysis, the meaning of wearable computer in fashion field was interpreted in this study, as a reflection of converged demand and tendency of this era. New issues for future research of the wearable computer were suggested in the viewpoint of fashion design.

The objective of this paper is to develop computer programs to aid in the design and analysis of control systems in which nonlinear characteristics exist. Control systems are dynamic systems, which can be described using various mathematical models. A convenient model for digital computer simulation is the state model in which described using a set of linear and non linear first order differential equations. The digital simulation was performed on a IBM PC/XT personal computer, and the computer language was BASIC. There are four possible configurations from which a user may choose. When running a program, the user is asked to enter the system parameters according to a specified control system configurations are; 1. A control system with a nonlinear element followed by a plant in a feedback configurations(NLSVF1). 2. A control system with a nonlinear device situated between two plants in a feedback configurations(NLSVF2). 3. A control system with a nonlinear element followed by a plant, followed by a the dealy in feedback configurations(TLAG). 4. A motor and load with a backlash nonlinearity between dynamic portions of the motor/load configurations (BACKLASH). The matrix from state equations are integrated using combination the trapezoidal method and fixed point iteration. Several cases which have nonlinearity were implemented on the computer and the results were discussed.

This paper represents the computer application techniques of initial and modification machining for dies with 3-dimensional scluptured surfaces. All procedures from die design to die machining and measurement are covered. The component of modelling is data management and modification (extrapolation and smoothing), surface modelling, and nc program preparation. Also this paper introduces the utility for successful and efficient operation of system such as map generation, data communication, tool path verification, contour map generation, graphic processing of extrapolation and smoothing results, and CAD/CAM system interface. Examples are given to illustrate the modelling.

소프트웨어 개발에 있어 프로그래밍의 어려움과 다양한 사용자 요구 사항의 빈번한 변화로 인한 시스템 설계와 구현사이의 문제는 항상 있어 왔다. 이러한 문제를 해결하기 위해 비프로그램 기반 응용 프로그램 시스템 설계에서는 개발자만이 시스템 소프트웨어를 수정하거나 구현하던 것을 최종 사용자에게 유연성을 증가시켜 시스템 설계와 구현사이의 문제점을 실행 시간(run-time)에 해결하기 위한 것이다.

C.I.P(corporate identity program)는 기업전략에 따른 개념을 기반으로 기업의 시각적 환경을 구성하는 각종 시각매체들을 일정한 규정에 의해 규격화, 표준화시키는 프로그램이며, 이에 따라 의도적이고 능동적으로 바람직한 기업의 이미지를 형성시키는 것이다. 그러나 최근의 급격한 기업환경의 변화에 따른 기업혁신과 새로운 형태의 기업의 등장은 기존 CIP개념의 변화를 요구하고 있다. 특히 기업이미지와 관련된 각종 시각매체들은 디지털화 되고있으며, 다양하고 새로운 시각매체들이 발생함으로서 여기에 적합한 아이덴티티디자인이 요구되고 있는 것이다. 최근의 새로운 기업환경에 적합한 특성을 가진 기업형태의 하나인 프랜차이즈 기업에 기존의 CIP 개념을 적용하는 것은 여러 가지 면에서 부족하고 부적절한 요소가 많다. 이미 오래 전부터 기업의 사무환경은 컴퓨팅환경에서 수행되고 있고 일반 가정이나 소규모 업소에서도 이제는 네트워킹을 통한 디지털화된 생활이 일반화된 현실이라 할 때, 이제 기업의 아이덴티티 디자인에서도 종래 CIP가 인쇄매체에 비중을 둔 것에서 벗어나 영상매체 및 새로운 첨단 정보매체에 까지 확대 적용할 수 있는 기능을 갖춰야 할 것이다. 이러한 이유로 본 연구에서는 프랜차이즈시스템에 관련된 아이덴티티 디자인을 F.I.P(franchise Identity programs)라 구별하고 그 개념과 세부적인 내용을 연구한다.

Purpose: The purpose of this study was to develop a finding meaning in life CD program about life-esteemed education and to identify the effect of the program. Methods: The life-esteemed education philosophy and the concepts of logotherapy were applied as a theoretical framework for this program. This program was developed through the process of planning, designing, developing, and evaluating with a content validity test. To identify the effect of the program, one experimental group design was applied to 54 students. Data were collected before the program started and one week and five weeks after the program finished. Results: The program was developed based on the students' needs and evaluation of the CD's content and consists of five periods: Dinosaur Park of Promise, Hill of Fragrance, Garden of Love, Forest of Acceptance, and My Lake. Each post-test score of knowledge, attitude, and practice on meaning of life was significantly higher than pretest scores. Conclusion: This program can be effective for life-esteemed education in elementary school students. Moreover, it is encouraged that the program will be utilized in more life-esteemed education for elementary school students.

Time Domain Reflectometry (TDR) has been extensively applied for various laboratory and field studies. Numerous different TDR probes are currently available for measuring soil moisture content and detecting interfaces (i.e., due to landslides or structural failure). This paper describes the development of an innovative spiral-shaped TDR probe that features much higher sensitivity and resolution in detecting interfaces than existing ones. Finite element method (FEM) simulations were conducted to assist the optimization of sensor design. The influence of factors such as wire interval spacing and wire diameter on the sensitivity of the spiral TDR probe were analyzed. A spiral TDR probe was fabricated based on the results of computer-assisted design. A laboratory experimental program was implemented to evaluate its performance. The results show that the spiral TDR sensor featured excellent performance in accurately detecting thin water level variations with high resolution, to the thickness as small as 0.06 cm. Compared with conventional straight TDR probe, the spiral TDR probe has 8 times the resolution in detecting the water level changes. It also achieved 3 times the sensitivity of straight TDR probe.
