The purpose of this study is to survey about the images of the sexy clothes that young women sympathize in modern society, that is, to make a research into the cognitive dimensions of 'Sexy image' and the constructive peculiarity of clothing. The researches into dimension of image by sexy clothing make that female mainly consist of in their twenties during May to October in 2003. The independent variables were: 1) The physical beauty dimension, 2) The negative estimate dimension, 3) The characteristic devaluation dimension,4) The elegance/ high grade dimension,5) The freshness/ beauty dimension,6) The sex appeal/ exposure dimension. Judging from each characteristic of costume in classified by articles, that is, colors, texture, shapes, details, and others-phenomenon of outerization of under clothing, print. We can know the clothes showing up our nice figures are the sleeveless design tied with strap, soft texture as silk chiffon and the colors that are not strong. And there were no embarrassed, ugly and pitiful clothing. Expressing sexy beauty by clothing is the result that the wearer produces intentionally by compounding design factors, it's the ideal when the observer's reaction and the wearer's intention correspond. Therefore, it will be helpful in expressing ideally if the subject, what kinds of sexy beauty the compounding design factors express, is studied carefully. Also it is expected to be used in grasping modem consumers' desires that want to look sexy, finding out how to express, dealing with the consumers' desires correctly, and the reference materials of the planning goods, sales promotion, and selecting of a medium of advertisement according to the consumers' desires.

Purpose: This study was done to identify changes in the image of the nurse for student nurses before and after their first clinical experience. Method: The participants were 108 nursing students who had not had any clinical experience. All participants had their first clinical experience for 1 week. and the image of the nurse was measured before and after the clinical experience. Result : 1) Before the first clinical experience, the scores on the image of the nurse that was the highest for the student nurses was in the professional dimension, followed by traditional, personal, and social in that order. After the clinical experience, the score on the image of the nurse was still the highest in the professional dimension, but this time, it was followed by personal, traditional and social dimension in that order. 2) Difference in the image of the nurse before and after the clinical experience showed statistical significance. The factors influencing this change were the degree of satisfaction with their major, whether the students had ever been hospitalized, and the type of wards where they had their clinical experience. Conclusion: In summary, the first clinical experience should be ideal in order to promote the image of the nurse. Therefore an improvement in the environment for clinical experience is important.

Purpose : (1) To analyse the effect of exposure time, ROI size and one impact factor in the image processing procedure on estimates of fractal dimension; and (2) to analyse the correlated relationship between the fractal dimension and the Cu-Eq value (bone density). Materials and Methods : The cylindric bone phantoms of 6 large and 5 small diameter having different bone densities respectively and human dry mandible segment with copper step wedge were radiographed at 1.0 and 1.2 sec esposure (70 kVp, 7 mA) using one occlusal film and digitized. Eleven rectangular ROIs from 11 cylindric bone phantoms and 4 rectan-gular ROIs from cortical, middle, periodontal regions, and socket of bone were selected. Gaussian blurred Image was subtracted from original image of each ROI and multiplied respectively by 1, 0.8, and 0.5, and then the image was made binary, eroded and dilated once, and skeletonized. The fractal dimension was calculated by means of a box counting method in the software ImageJ. Results : The fractal dimension was decreased gradually with continued bone density decrease showing strong correlations (bone phantom; r> 0.87, bone; r> 0.68) under 70 kVp 1.0 sec M = 0.8. Fractal dimensions showed the significant differerence (p < 0.05) between two different exposure times on the same small ROI of bone phantom. Fractal dimensions between two different sizes of ROI on bone phantom showed the significant differerence (p < 0.05) under 1.2 sec exposure, but did not show it (p > 0.05) under 1.0 sec exposure. Conclusions : Exposure time, ROI size, and modifying factor during subtracting could become impacting on the results of fractal dimension. Fractal analysis with thoroughly evaluated method considering the various impacting factors on the results could be useful in assessing the bone density in dental radiography.

Moire topography method isa well-known non-contacting 3-D measurement method as afast non-contact test for three-dimension shape measuring method. Recently, it's important to study the automatic three-dimension measurement by moire topography because it is frequently applied to the reverse engineering , the medical , the entertainment fields. Three-dimension measurement using projection of moire topography is very attractive because of its high measuring speed and high sensitivity. In this paper, the classical moire method is computerized-so called digital moire when a virtual grating pattern is projected on a surface, the captured image by the CCD camera has three-dimension information of the objects. The moire image can be obtained through a simple image processing and a reference grating pattern. and it provides similar results without physical grating pattern. digital projection moire topography turn out to be very effective for the three-dimension measurement of objects. Using different N-bucket algorithm method of digital projection moire topography is tested to measuring object with the 2-ambiguity problem. Experimental results prove that the proposed scheme is capable of finding measurement errors that decreased more by using the four-three step algorithm method instead of the same step in the phase shifting of different pitch.

Due to its simplicity and high reliability, the box-counting(BC) method is one of the most frequently used techniques to estimate the fractal dimensions of a binary image with a self-similarity property. The fractal calculation requires data sampling that determines the size of boxes to be sampled from the given image and directly affects the accuracy of the fractal dimension estimation. There are three non-overlapping regular grid methods: geometric-step method, arithmetic-step method and divisor-step method. These methods have some drawbacks when the image size M becomes large. This paper presents a BC algorithm for enhancing the accuracy of the fractal dimension estimation based on a new sampling method. Instead of using the geometric-step method, the new sampling method, called the coverage ratio-step method, selects the number of steps according to the coverage ratio. A set of experiments using well-known fractal images showed that the proposed method outperforms the existing BC method and the triangular BC method.

This study presents work to utilize RADARSAT SAR image for forecast oil slick trajectory movement. The fractal dimension algorithm used to detect oil slick. The Doppler frequency shift and quasi-linear model was used to simulate a current pattern from RADARSAT image. The Fay’s algorithm of oil slick spreading was developed based on a Doppler frequency shift model. Thus, the study shows that fractal dimension algorithm discriminated the oil slick from the surrounding water features. The quasi-linear model shows that the current pattern can be simulated from single RADARSAT image. The oil slick trajectory model shows that after 48 hrs, the oil slick parcels deposited along the coastal waters.

This study was one of a series of studies on application of machine vision and image processing to extract the geometrical features of plants and to analyze plant growth. Several algorithms were developed to measure morphological properties of plants and describing the growth development of in-situ lettuce(Lactuca sativa L.). Canopy, centroid, leaf density and fractal dimension of plant were measured from a top viewed binary image. It was capable of identifying plants by a thinning top viewed image. Overlapping the thinning side viewed image with a side viewed binary image of plant was very effective to auto-detect meaningful nodes associated with canopy components such as stem, branch, petiole and leaf. And, plant height, stem diameter, number and angle of branches, and internode length and so on were analyzed by using meaningful nodes extracted from overlapped side viewed images. Canopy, leaf density and fractal dimension showed high relation with fresh weight or growth pattern of in-situ lettuces. It was concluded that machine vision system and image processing techniques are very useful in extracting geometrical features and monitoring plant growth, although interactive methods, for some applications, were required.

Purpose: This study was to investigate the image of nurse perceives by students of elementary and middle schools in Seoul, Korea. Methods: The data were collected through questionnaire survey on 860 students. The survey was performed during May to Jun. 2003. The nurse image was analyzed through the instrument conceived by Il-Sim, Yang(1998) on the basis of four dimensions; traditional, social, professional and personal. The collected data analyzed using SPSS 11.0 with frequency, mean, standard deviation and t-test. Results: The results of this study were as follows. 1. There was a significant difference in the nurse's image between elementary and middle school students(p=.000), and the elementary students had more positive image. 2. The nurse's image of elementary school students had more positive than middle school students in traditional(p=.000), social(p=.000), professional(p=.000) and personal dimension(p=.015). In elementary school students, score of nurse's image was the highest in personal dimension, followed by traditional, professional and social in order. In middle school students, score of nurse's image was the highest in personal dimension, followed by professional, traditional and social in order. 3. The difference of nurse's image not showed statistical significance in sex, religion, experience of hospitalization(self), experience of hospitalization (family), nurses in family by general characteristics. Conclusion: As a result, elementary school student had more positive nurse's image than middle school student in all the aspects. But as they grow old, it changed negative. It is required to develop public information or education fit with student's age to image making by broadcasting and to improve the image nurses themselves.
