In recent, the marketing competitions that stimulates the emotions of consumers are intensifying in the domestic construction industry due to the increase of unsold new apartments. However, there is a need for brand identity establishment through which more differentiated information can be delivered to the consumers, as each brand is focusing only on idealistic image advertisements of dream, future and happiness. Accordingly in this study, the top five brand apartments according to the national brand value evaluation index (BSTI, BrandStock Top Index) were selected and analyzed their TV advertisement characteristics, and its purpose is in evaluating the brand images perceived by the consumers of their TV advertisements. The significance of the results from this study is in presenting the basic information for establishing effective communication between the corporations and consumers. The survey research of this study was conducted for the students of D University, and SPSS 14.0 program was used for the statistical data analysis.

Occurrence of earthquakes have been increased all over the world and also, magnitude of earthquakes have been larger these days. Earthquake can be happened in Korea and is not a safe country any more. Many buildings are exposed at danger without any alternatives against earthquake in Korea. Among various kinds of buildings, school buildings are very important and urgent, because many students stays at school and young students have some difficulty to evacuate. Also, most existing school buildings in Korea were not designed considering earthquake resistant design codes. Thus, in this study, 3 types of braces were applied for seismic retrofits of existing school buildings using commercial structural analysis software and effective seismic retrofits were evaluated and discussed based on results by time history analysis.

There is basic problem with the current evaluation method for character recognition systems. The current method evaluates the average recognition rate by applying the test data to the target system. The average recognition rate tells no more than and no less than the overall performance and it depends on the data. In this paper we propose a testing method which will analyze the target system and point out its strong points and weak points. This can be made possible through using the data which are generated cy distorting the standard character images according to a carefully controlled manner. This paper will describe how to automatically generate such distorted images. Also we will show the method is actually effective and useful by applying it to evaluating existing recognition algorithms.

A double cantilever sandwich-beam method has been applied to the evaluation of the frequency dependence of dynamic elastic modulus and material loss factor of EPDM rubbers. The flexural vibration of a double cantilever sandwich-beam specimen with an inserted rubber layer was studied using a finite element simulation in combination with the sine-sweep test. Effects of the rubber layer length on the dynamic characteristics were also investigated: reliable values were measured when the length of the inserted rubber layer was larger than and equal to 50% of the effective specimen length. The values were compared with those obtained by the dynamic mechanical analysis and the simple resonant test. Relationships of the dynamic characteristics of rubbers with frequency could be determined using the least square error method.

Recent studies among various activities taking place in order-picking warehouse system have shown various researches to reduce the order-picking costs occupying more than half the total costs. One way of improving the warehouse system performance is to separate from a picking area and a reserve area in one unit rack. This study is concerned on the performance evaluation model for picking and replenishing facility of refrigerated warehouse using simulation method. In this study, we developed a mathematical model to compute the system performance solve this problem using simulation method. We demonstrate the system performance using AutoMod Simulator and verify the results to compare mathematical results of the system performance of warehouse system. A systematic approach proposed n this study for an optimal planning of order-picking warehouse is known as an effective method for planning of order-picking warehouse and a performance evaluation problem considering both picking and replenishment.

Material degradation is a multibillion-dollar problem which affects all the industries amongst others. The last decades have seen the development of newer and more effective techniques such as Focused-ion beam(FIB), Transmission electron microscopy(TEM), Secondary-ion mass spectroscopy(SIMS), auger electron spectroscopy(AES), X-ray Photoelectron spectroscopy(XPS) , Electrochemical impedance spectroscopy(EIS), Photo- stimulated luminescence spectroscopy(PSLS), etc. to study various forms of material degradation. These techniques are now used routinely to obtain information on the chemical state, depth profiling, composition, stress state, etc. to understand the degradation behavior. This paper describes the use of these techniques specifically applied to materials degradation and failure analysis.

FDG-PET has potential as an effective, non-invasive tool to measure tumor response to anticancer therapy. The changes in tumor FDG uptake may provide an early, sensitive guide to the clinical and subclinical response of tumors to cancer treatment, as well as functional assessment of residual viable tumor. This may allow the evaluation of subclinical response to anticancer drugs in early clinical trials and improvements in patients management. However, monitoring tumor responses with FDG-PET is still in its infancy. The methods of measurement of FDG uptake are currently diverse and timing with respect to anti cancer therapy variable. Therefore, there is a need for larger-scale trials along with standardized methodology and a collection of reproducibility data. The recent guideline from the European group seems to be the most comprehensive. In future, the combination of morphological and metabolic images may improve the quantitative nature of these measurements by relating tumor viability to total tumor mass. More data on sensitivity and specificity of FDG-PET technique are needed along with continued advancement of PET methodology.

Fabric hand was assessed for 14 women's spring-fall dress fabrics based on the subjective hand evaluation scale developed in the part 1 of this study. The effects of fabric type, seam and dress style on the subjective hand evaluation of 470 Korean consumers (205 textile experts and 265 non-experts) were investigated. Mechanical properties obtained from KES-FB system were compared with the each dimension of subjective hand expression. The type of fiber and construction were considered to be important factors in affecting hand assessment of Korean consumers, however, the presence and type of seam were not considered to be important. There were certain characteristics of subjective hand attributes for each dress style. Surface properties of fabrics, even though it is not strictly mechanical properties, appeared to be the most effective dimension in the developement of new products which appeal to Korean conssumers.

The usage of nondestructive testing on early-aged concrete leads to enhacned safty and allows effective scheduling of construction, thus making it possible to maximize the time and cost efficiencies. In this study, a reliable nondestructive strength evaluation method for early-aged concrete using the longitudinal wave velocity is proposed. Compression tests were performed to examine factors influencing the velocity-strength relationship of concrete, such as water-cement (w/c) ratio, fine aggregate ratio, curing temperature, and curing condition. The test results show that a change in the w/c ratio and curing temperature has minor effect on the velocity-strength relationship/ However, curing condition significantly influences the velocity-strength relationship of early-aged concrete. Moreover, the longitudinal wave velocity increases with decreasing fine aggregate ratio. It is concluded from this study that the strength evaluation of early-age concrete can be achieved by a nonlinear equation which considers the effects of curing condition and fine aggregate ratio.

This paper proposes a dynamic moment algorithm to control oscillaion before the convergence of the KR(Kernel Relaxation). The proposed dynamic moment algorithm can be controlled to convergence speed and performance according to the change of the dynamic moment by teaming training. we used SONAR data that is a neural network classifier standard evaluation data in order to do impartial performance evaluation. The proposed algorithm has been applied to the KP (kernel perceptron), KPM(kernel perceptron with margin) and KLMS(kernel lms) as the kernel method presented recently. The simulation results of proposed algorithm have better the convergence performance than those using none and static moment.
