One of the most important processes is the face milling in processing task. It makes the smooth surface of processed goods. In processing stage, the formation of burr is inevitable. The formed burr decreases a detailed drawing and effects the safety of workers. So, it causes a deburring process for removing and a bottle-neck condition. Therefore, the study which can minimize the generation of burr is needed. In this paper, complex feature, such as line, arc, circle, spline is studied more reality than any other papers. And also, the algorithm which can predict the path of generated burr is established. Moreover, the finality goal is that the system which can produce tool-path minimized has to be developed.

This study establishes a simple Causal Map in order to understand the structure of Social Network Services(SNS). From this, the paper proposes a simulation with drawing Simulation Model and it examines whether a Dunbar Number is available for the emergence of collective intelligence based on an on-line network. Through my analytical research, it turn out both Closed SNS and Open SNS have their own Dunbar Number. However, it appear that Open SNS can expand infinitely as it has a unique property namely weak tie. This implies that it is significant for a system or policy to be developed in order to overcome the problem of Dunbar Number, whereas restricting the extension of a network by considering the Dunbar Number would have a negative impact on emergence of collective intelligence.

Purpose: The purpose of this study was to identify the type of sexual assertiveness of female adolescents. Methods: A Q methodology which provided a method of analyzing the subjectivity of each type was used. Thirty-three female high school students classified 40 selected Q statements into 9 points standard. The collected data was analyzed by using the PC-QUNAL program. Results: Four types of sexual assertiveness manifested by female adolescents were identified: Type 1: Self-normative line-drawing type, Type 2: Pleasure-seeking negotiation type, Type 3: Passive relationship maintenance type, Type 4: future-oriented satisfaction-delay type. Conclusion: This study is meaningful because it provides empirical information necessary for the development of theories by verifying integrated attributes related to the female adolescents' sexual assertiveness. Results also induced the measuring tools and succeeding studies, and presented educational material for sex education that is tailored to the developmental level and characteristics of female adolescents.

Copying of designs has been condoned in the fashion industry. However, the industry argues that whether fashion design should be protected by law and what constitute design copying in fashion. This study has been performed by in-dept interviews with employees in the fashion industry. The study finds that respondents perceived copying of design to be some extent beneficial to the industry. While, they also observed that it has a negative effect on the industry due to indiscriminate copying. In regards to standard of drawing the line between copying and inspiration or modification, designers have subjective and discrepant standards. Fashion industry itself, consumer's biased preference, inefficient education and lack of legislation are significantly engaged in design copying.

The most remarkable and characteristic problem of design is that of creativity of design. Originality is a part of creativity. In the process of designing, we used to handle design thoughts that shows some patte군 of divergent and productive thoughts. During design thinking, for example 'Idea sketch', We also are under Pattern Recognition and Gestalt principles organization. In this study, it is reorganized that the 'Originality Test of Line Drawing(OTLD)'is a measurement system for personal originality. There is a regression on two tests of OTLD, which has 1 Semester Interval. From the regression data, Test2 = 7.763 + 0.643Test1, F value : 55.219, Prob : 0.0001. We would suggest a measurement system for an ability of originality in design fields, but we couldn't find any reliability and validity for Fine Art fields. In this point, OTLD could be a development tool for design creativity.

In this paper, we discuss about the real-time distributed system for the control of to motors using uCOS-II kernel. Real-time kernel needs to process the tasks for two motors in desired time to synchronize motion. We used both semaphore and message mail box for synchronization. In the previous study, we used step motors for the actuator of two axes robot, but could not draw a clear line because of motor resolution and synchronizing step pulse. To resolve the problem we rebuilt the transfer robot with DC motors and the dedicated position servor which had built in out lab. Moreover we developed the PC based graphic user interface for generating planar drawing image control. Experimental results also presented to show the proposed control system is useful.

This paper presents development of practical and universal program that is applied to ${\pi}$ loop system which is based on basic algorithm of network optimization for reduction investment cost and rationalization of underground plan. This system is ease to input and modify about information of powerline drawing, that is, can input easily condition of their calculation referring to candidate of underground apparatus under using digitizer.

In order to investigate the formability of friction stir welded(FSW) tailor welded blanks(TWB) with respect to the base material's directional combination, aluminum alloy AA6111-T4 sheets were welded with three different conjoining types: RD-RD, TD-RD and TD-TD. Here, RD and TD represent rolling and transverse directions, respectively. For experimental formability study, three tests with gradual complexity were performed: the simple tension test with various weld line directions for uni-axial elongation, the hemisphere dome stretching test for biaxial stretching and the cylindrical cup deep drawing test. As a result, all three forming tests showed that RD-RD type samples exhibited the best formability, while TD-TD type sheets showed the least formability performance.

This paper summerizes the former 5 papers that studied computer programming for the estimation of the Weibull, Extreme value, Hazard, Normal and Log-normal parameters which have a close relation with the reliability of the various kinds of industrial products. Probability paper is very commonly used in estimating the parameters, however, it is very hard to neglect the errors in plotting the data, and especially in drawing the regression line. The main purpose of this paper is to reduce these errors and to help the engineers to use the parameters in improving the reliability of their prod- ucts. The following parts are included in the computer programming with the em- phases on significant digits and rounding of numerical values : $\bullet$ data input part for various cases $\bullet$ parameter estimation part $\bullet$ printing part for input data $\bullet$ printing part for the results $\bullet$ printing part for the graphic(probability paper). And the running results(monitor displays) of the program for a fictitious example of Weibull distribution is given for the interested ones.
