  • 2-D and 3-D resistivity surveys were carried out at the Deok-In2 levee during the period of arid and rainy seasons to assess the waterproof effectiveness of sheet pile and grouting sections and detect the location of pipings. Inverted resistivity sections clearly indicated the boundaries of sheet pile and grouting sections and the locations of pipings observed at the ground surface. Besides, GPR survey was carried out to verify the rear cavity of culvert in levee which is thought to be the major cause of levee breakdown, But the quality of GPR data was very poor due to the steel reinforcements buried in the culvert. Because it is not easy to apply various geophysical surveys upon concrete structures, newly designed hydraulic response test was proposed to assess the continuity of rear cavity of culvert in this study.

  • The objective of this article is to examine the possibility of 'story-telling' as united concept of causality and subjectivity through sequence combination, and the 'similarity' between object and image in fashion photographs making diversity of meanings. To analyze and investigate the research, as evidential data this paper used the photos of Steven Meisel from 2002 till 2007 Vogue published in Korea, U.S, and Italy, as well as other visual data like graphic collections, catalogs, art-related data and internet data. This research runs both theoretical and positive investigations to suggest the function of story-telling in the Process of opened-communicative roles of fashion photos. Thus this paper investigated Steven Meisel's storytelling in his fashion photos; short moment of event, continuity of time, compound of sequence, and complexity of viewpoint. This paper also studied the aesthetic characteristics of Steven Meisel's fashion photos as categories of overlapped meaning, arbitrariness of interpretation, exclusivity of message, and decoding. The research result suggests that clothing not only includes current age's value but also among social constitutions it includes multilateral characteristics. Ultimately this paper is also making meaning alive by cutting off the chain of 'firm' meanings of fashion photo. That seems like opening the opportunity for correctly understanding fashion's meaning which has the aspects of ambivalence of changing meanings and values by the motivation of context and text.

  • The feature extraction mechanism of the CASA(Computational Auditory Scene Analysis) system uses time continuity and frequency channel similarity to compose a correlogram of auditory elements. In segmentation, we compose a binary mask by using cross-correlation function, mask 1(speech) has the same periodicity and synchronization. However, when there is delay between autocorrelation signals with the same periodicity, it is determined as a speech, which is considered to be a drawback. In this paper, we proposed an algorithm to improve discrimination of channel similarity using Weighted Cross-correlation in segmentation. We conducted experiments to evaluate the speech segregation performance of the CASA system in background noise(siren, machine, white, car, crowd) environments by changing SNR 5dB and 0dB. In this paper, we compared the proposed algorithm to the conventional algorithm. The performance of the proposed algorithm has been improved as following: improvement of 2.75dB at SNR 5dB and 4.84dB at SNR 0dB for background noise environment.

  • In this paper, a shape design sensitivity analysis(DSA) method is presented for Mindlin plates using an isogeometric approach. The isogeometric method possesses desirable advantages; the representation of exact geometry and the higher order inter-element continuity, which lead to the fast convergence of solution as well as accurate sensitivity results. Unlike the finite element methods using linear shape functions, the isogeometric method considers the exact normal vector and curvature of the CAD geometry, taking advantages of higher order NURBS basis functions. A selective reduced integration(SRI) technique is incorporated to overcome the difficulty of 'shear locking' phenomenon. This simple technique is surprisingly helpful for the accuracy of the isogeometric shape sensitivity without complicated formulation. Through the numerical examples of plate bending problems, the accuracy of the proposed isogeometric analysis method is compared with that of finite element one. Also, the isogeometric shape sensitivity turns out to be very accurate when compared with finite difference sensitivity.

  • Those students with ability and interest in science should be supported to develop their potential and to reach high levels of achievement in science and technology. In order to ensure that gifted pupils are able to enhance their creativity as well as research abilities, appropriate learning programs and environments are essential. One of the various teaching and learning models for the gifted in science is the discovery learning model based on inductive science activities. There is a clear line of continuity between knowledge discovery at the forefront of research and student's learning activities. If students receive excellent training in organizing scientific concepts for themselves, they will be able to skillfully apply appropriate scientific concepts and solve problems when facing unfamiliar situations. It is very important to offer an appropriate learning environment to maximize the learning effect whilst, at the same time, understanding individual student's characteristics. In this study, the authors took great pains to research effective learning environments for gifted science students. Firstly, appropriate classroom learning environments thought by the teacher to offer the most potential were investigated. 3 different classes in which a revised teaching and learning environment was applied in sequence were examined. Inquiries were conducted into students' activities and achievement through observation, interviews, and examination of students' worksheets. A Science Education expert and 5 elementary school teachers specializing in gifted education also observed the class to examine the specific character of gifted science students. A number of suggestions in discovery learning classes for elementary students gifted in science are possible; 1) Readiness is essential in attitudes related to the inquiry. 2) The interaction between students should be developed. A permissive atmosphere is needed in small group activities. 3) Students require training in listening to others. In a whole class discussion, a permissive atmosphere needs to be restricted somewhat in order to promote full and inclusive discussion. 4) Students should have a chance to practice induction and abduction methods in solving problems.

  • The purpose of this research is to understand the meanings and essentials of the experience of continuous participation in volunteer works, from an emic perspective. To conduct an in-depth study regarding 'live experiences', this research used phenomenological research method. For the method of data collection, purposive sampling is used with some in-depth interviews of five elderly people who have participated in volunteer works from 6 years to 23 years. As a result of the analysis of the collected data, the essence of continuous participation in volunteer works appeared to be 'regained happiness of life'. Elderly people who persist in volunteering were also passionate in taking part in social activities, eager to improve their cognitive functions, and likely to put more effort in maintaining their own health in order to continue the volunteer works. These are the factors that satisfy successful ageing. This research has its object in preparing systematic support at a national level to prevent the volunteer works of the elderly people from ending up in mere personal virtue, so as to successfully manage the later stage of life.

  • In land reclamation construction using marine clay, a measure of material function, that is, the relation between void ratio-effective stress and permeability, is very important aspect for the prediction of self-weight consolidation behavior. But reclaimed ground has very high water content, so there are many difficulties in the laboratory test for measuring material function. For this reason, some researches are carried out using slurry cconsolidometr to measure material function. In this study, material function was measured using slurry consolidometer, and to overcome the shortcoming of researches using slurry cosolidometer, an equation for the prediction of material function was proposed on the basis of column test's parameter. Material function was determined through low stress consolidation test and permeability test, and it also was calculated with the equation using column test parameter. The continuity of material function could be confirmed through these tests. Material function is easily determined with the equation proposed in this study, and can be used for the prediction of self-weight consolidation behavior.

  • The purpose of this study was to find the effects of an educational program for primiparas on maternal confidence and continuity of breastfeeding. The subjects of this study were the healthy mothers, and the healthy infants whose weight was more than 2.500gm and gestational age was more than 37 weeks. The final targets were thirty seven mothers-19 of intervention group and 18 of control group. Data were collected from 15th of March to 3rd of September, 1999. To the intervention group, education on infant care and breast feeding were provided before discharge. And that, telephone advice was provided within one week after discharge, and at 2 months postpartum. And that, reeducation and counsel were provided at one month and three months postpartum by home-visiting care for the intervention group. For the control group. home visiting was also conducted only for data collection. Data were analyzed by chi-square test and t-test. The results were as follows: 1. The maternal confidence of the experimental group was higher than that of control group at one month postpartum. but the difference of confidence of these two groups were not significant at three months postpartum. 2. For both of experimental and control groups, maternal confidence significantly increased at three months postpartum than one month postpartum. 3. The rate of breastfeeding of the experimental group was higher than that of control group at one month and two months postpartum (p=.050, p=.049). But the difference was not significant at three months, although experimental group continued breastfeeding more(47.4%) than control group(27.8%). In conclusion, educational program for primiparas of this study was effective in the promotion of maternal confidence and breastfeeding.
