Whitehead is a greatest mathematical philosopher who expanded mathematical concepts and method in philosophy. In view of Whitehead that he emphasizeson metaphysical perspective, mathematical truth and empirical connection of reality, it explicates that it tends to empiricism and rationalism of mathematical philosophy. In this paper, we try to research his unique perspective of mathematical philosophy. His perspective on organic philosophy is combination of empiricism trend and rationalism trend of mathematical philosophy.

This study examined the effect of ambivalent fashion consuming tendency on continuous information search and fashion store selection. Surveys period was from Jan. 8th to Jan. 20th in 2014. The subjects of this study were the young 218 women who had the shopping experiences with ambivalent fashion consuming tendency in their 20s of Pusan and Kyung-nam. These surveys referred to the relevant preceding researches and were completed by some pilot researches (focus group interview, paper-pencil test). The data was analyzed by frequency analysis, reliability analysis (Cronbach's ${\alpha}$), factor analysis and regression analysis. The main results of this study were summarized like following: First, this study was based on the definition and characteristics of the ambivalent fashion consuming tendency. The current ambivalent fashion consuming tendency consisted of price ambivalence, trend ambivalence and brand ambivalence. The consumer's demographic characteristics affected trend ambivalence, brand ambivalence. Second, continuous information search was composed of entertaining information search and rational information search. Third, ambivalence fashion consuming tendency had a strong influence on continuous information search (information search and share activity). Forth, the price ambivalence, trend ambivalence and brand ambivalence, which is the factors of ambivalent fashion consuming tendency, significantly impacted on selecting the fashion store. In conclusion, ambivalent fashion consuming tendency is main related factor impacting on continuous information search and fashion store selection.

In recent years, demand of make up products has been suddenly increased, and colors n make up products have been also emphasized. For these reasons, prior to every season each cosmetics cooperation supplies new colors and informations with based on color trend. But, in addition to color, various functions such as treatment effect, long lastingness, non-transferring and transparent glossiness have been also require by consumers. In this paper, the whole changes and technical trends of make up cosmetics are described, and in addition, the psychological effects of make up are introduced.

The MSC is a high resolution multi-spectral camera system which is mounted on the KOMPSAT-II satellite. The electro-optic camera system has a refocusing mechanism which can be used in-orbit by ground commands. By adjusting locations of some elements in optics, the system can be focused precisely. The focus mechanism in MSC is implemented with stepper motor and potentiometer. By reading the value of the potentiometer, rough position of the motor can be understood. The exact location of the motor can not be acquired because the information from the potentiometer can not be so accurate. However, before and after certain events of the satellite, like a satellite launch, the direction of the movement or order of the magnitude of the movement can be understood. In this paper, the trend analysis of the focus motor position during the ground test phase is introduced. This result can be used as basic information for the focus calibration after launch. By studying the long term trend, deviation from the best focal point can be understood. The positions of the focus motors after launch are also compared.

In enterprise software projects, performance issues have become more critical during recent decades. While developing software products, many performance tests are executed in the earlier development phase against the newly added code pieces to detect possible performance regressions. In our previous research, we introduced the framework to enable automated performance anomaly detection and reduce the analysis overhead for identifying the root causes, and showed Statistical Process Control (SPC) can be successfully applied to anomaly detection. In this paper, we explain the special performance trend in which the existing anomaly detection system can hardly detect the noticeable performance change especially when a performance regression is introduced and recovered again a while later. Within the fixed number of sampling period, the fluctuation gets aggravated and the lower and upper control limit get relaxed so that sometimes the existing system hardly detect the noticeable performance change. To resolve the issue, we apply dynamically tuned sampling window size based on the performance trend, and Fuzzy theory to find an appropriate size of the moving window.

As the cost of the operational spacecraft simulator is a large portion of the spacecraft cost and its requirements increase, it is given the pressures to reduce the cost and the development period. For that reason, the space industry with the coordination of ESA has made a study of the reuse in a wide scope across space projects. Its scope includes not only simulation software itself but also software requirements, design, work experience and developing process/methodology. The standard for simulator model portability and the efficiency enhancement of the development process as a result have been successfully applied to several projects. This paper describes the recent trend of the spacecraft simulator in Europe and the present status of its the study and the development.

The analysis and examination of this study are focussed on the external deconstruction trend expressed in the works of Jean Paul Gaultier. The external deconstruction is a way of expression faithful to the literal meaning of 'deconstruction' and is the applied case of exposure, destruction, poverty, and decomposition as they are. The method and scope of this study are from 1980's to present, and the followings are the results of this examination focussed on the various literature of philosophy, aesthetics and literary criticism, and the domestic and foreign fashion journals. The exposure phenomena through the deconstruction expressed repeatedly in the works of Gaultier deconstructed the fixed idea of 'the inner wear should be worn inside the outer wear' and at the same time denied the dichotomical interpretation of the exposure and suppression, the traditional beauty and decadent beauty, the chastity and unchastity, the asceticism and sexuality, and obscured the notion of the inner wear and outer wear. The destructive deconstruction expressed in the works of Jean Paul Gaultier introduced the elements such as hippy, punk, and kitsch, slashed before making dresses, crumpled unseemly like wastepaper, or made dresses with textures like paper scraps, and through destroying textures, yielded shock effects and tension. Poverty, through borrowing from the outwardly poor-looking elements of design, i.e. the patch work, decolor, dye, fading, fringing, incompletion, and handmadeness, liberated dresses and their ornaments from the outside. The traditional dresses were dresses having certain forms with formative beauty, but Gaultier disassembled dresses and raised questions about the logic of dresses themselves.

In order to cut the round bale easily, a roughage cut-feeder for the round bale was developed in this study. This study consists of two parts. One is development of a cutting mechanism and a performance test reported in the previous paper. This is the second part of the study. For the study, recent trend of traditional cutting system was analyzed. Also, cost of the prototype cut-feeder was analyzed and determine the break-even point of farm size was determined by comparing with traditional method using a traditional cutter. A prototype cut-feeder was investigated with the fact that working performance, fiber length and shape of roughage and feeding quality was good. Operating cost of the prototype cut-feeder decreased rapidly with an increase of farm size. Break-even point in terms of farm size was 36 heads for beef and 28 heads for dairy. Also, costs estimated were 118,000 won/head year and 148,000 won/head year, respectively.

Repeated measurement data among several treatments with a control is often used in the field of medicine study. In this paper, we suggest a method for comparison of the linear trend of responds followed time among several treatments with a control based on repeated measurement data. First, we estimate slope from each subject and generate samples using the slope estimated previous. And then, we test the difference among treatment with a control by ANOVA F test, Jonckheere-Terpstra test, updated control group procedure using generated samples. Monte Carlo Simulation is adapted to compare the power and experimental significance levels in various configuration.

Nanomaterial have grown from scientific interest to commercial products and the nanomaterial market has grown 19.1 % each year. As the nanomaterial market size increases, it is expected that nanomaterial production will increase and its contamination of outdoor environmental system will also increase in the form of industrial waste. Since most of nanomaterials are known as biologically non-degradable materials, nanomaterials will accumulate in the environment, and this will increase the potential threats to human health along the food chain. Recent studies have investigated the toxicity effect of nanomaterials due to their size, chemical composition and shape. For the development of nanomaterial while taking human health into consideration, a nanomaterial detecting sensor is required. In this paper, we have observed the trend of nanomaterial detecting sensor of mechanical, electrochemical, optical and kelvin probe force microscopy sensors and we believe that this trend will shed the light on the development of real-life nanomaterial detecting sensors.
