Free-field ground motion during earthquake is significantly affected by the local site conditions and the behavior of structure is influenced by ground motion, it is essential to perform the reliable site characterization and to determine the site specific earthquake response. In this study, case study of site specific ground response evaluation was performed at Inchon area. Step by step procedures for site characterization and one-dimensional site response analysis were introduced and the importance of site specific analysis was verified.

The relationship between the performance measures and the acceptance of evaluation has been of importance not only in the academic field but in the business area. However, there had not been many studies on the factors which affect the goal core, that is, specificity and difficulty. The previous literature on the evaluation of measures has limitations in that the common and unique measures without suggesting the concept of shared measures are used. Thus, the purpose of this study is to examine the effects of the environmental characteristics of the goal setting on the result and acceptance of the evaluation, which is mediated by the characteristics of the goal core. This study further tests if there are any moderating effects from using the shared measures of performance.

In this paper, an evaluation of intelligent CCTV system is proposed with recording and implementation video and video DB. Videos for evaluation are recorded by dividing far, mid and near zone. Video DB has video recording information, detection area, and ground truth in XML format. A video annotation tool is proposed to make ground truth effectively in this paper. A video annotation tool writes ground truths of videos and includes evaluation comparing system alarms with ground truths.

This study intended to interpretate the current value of the cultural landscape resources in Gwansan region, Gwangju-si. The 35 significant cultural landscape resources in Gwangsan region appear education, people in history, living residence, religion & belief, distribution of cultural site, tomb, industry, topographic scenery characteristics. They are classified such as 22 traditional landscape resources, 7 modern landscape resources, 6 natural landscape resources. The significant cultural landscape resources were evaluated by value items of 4 natural landscape, 4 social, and 5 cultural. As a result of value evaluation on the cultural landscape resources in Gwangsan region, the highest value were appeared on the cultural items, while the lowest value were appeared on the social items. And high evaluation were appeared on regional identity, cultural preservation, regional monumentality, visibility, while low evaluation were appeared on unique naturality and connectivity of assets.

Altmetrics is an emergent research area whereby social media is applied as a source of metrics to evaluate scientific impact. Recently, the interest in altmetrics has been growing. Traditional scientific impact evaluation indictors are based on the number of publications, citation counts and peer reviews of a researcher. As research publications were increasingly placed online, usage metrics as well as webometrics appeared. This paper explores the potential benefits of altmetrics and the deep relationship between each metrics. Firstly, we found a weak-to-medium correlation among the 11 altmetrics and visualized such correlation. Secondly, we conducted principal component analysis and exploratory factor analysis on altmetrics of social media, divided the 11 altmetrics into four feature sets, confirming the dispersion and relative concentration of altmetrics groups and developed the altmetrics evaluation model. We can use this model to evaluate the scientific impact of articles on social media.

The purpose of this study are to obtain basic materials that can be fulfil effective using of space by consider living behavior and attitude, a furniture usage and a space usage according to the usage of bed in An-Bang. It also suggests a plan about a method of furniture usage that is reflected resident’s living behavior and attitude, desire, consciousness through the space evaluation. The major findings of this study can be summarized as follow : 1, The case of husband’s age was less than 47, and the educational level of husband and wife was above a university graduate, the percentage of possession of bed was high. 2. According to the usage of bed, this study showed difference of furniture usage, and that of life action. 3. According to the usage of bed, there were significant differences in the luxury by result of the space evaluation. 4. Also, there were significant differences in a satisfaction of atmosphere, and an area by satisfaction of furniture usage. 5. According to the usage of bed, the influence of each independent variable appeared differently by result of regression analysis to see the space evaluation effect on space satisfaction.

The destructive method is reliable and widely used for the estimation of material degradation but it have time-consuming and a great difficulty in preparing specimens from in-service industrial facilities. Therefore, the estimation of degraded structural materials used at high temperature by nondestructive evaluation such as electric resistance method, replica method, Barkhausen noise method, electro-chemical method and ultrasonic method are strongly desired. In this study, various nondestructive evaluation(NDE) parameters of the Barkhausen noise method, such as MPA(Maximum Peak Amplitude), RMS, IABNS(Internal Area of Barkhausen Noise on Signal) and average amplitude of frequency spectrum are investigated and correlated with thermal damage level of 2.25cr-1.0Mo steel using wavelet analysis. Those parameters tend to increase while thermal degradation proceeds. It also turns out that the wavelet technique can help to reduce experimental false call in data analysis.

The cases of welders illness by welding fume generated during arc welding are recently reported, which makes the legal regulation in the welding work place. Also, this situation makes the employers and welders be concerned about the welding fume seriously. At this point of time it is necessary that a standard testing method is developed as a fundamental tool for the evaluation of Fume Generation Rate(FGR) required for making progress in the development of low fume electrodes and welding process technology and also constructing the ventilation system in welding area. However, the current standard(KS D 0062) is only applicable to the manual covered electrode arc welding. In this study the evaluation procedure for the FGR is established by developing the fume collection chamber which can be applicable to semiautomatic and automatic arc welding as well as manual arc welding. This evaluation system and procedure can be used as a tool not only to develop the low fume welding electrode and welding process technology but also to construct the equipment controlling the welding workshop atmosphere.

Recently, Avatar business has in favor on the internet and lots of profit has been increasing. In this study, we apply evaluation criteria for clothing purchase to Avatar, and try to find out the differences of the evaluation criteria by the age and sex. There are many forms in the evaluation factors for purchasing clothes of Avatar by categorizing into five primary factors with statistical tool among them. At this point, future research should use these results for the area of the customer management and marketing in Avatar business on the internet.

This study focuses on the evaluation of the streets on residential areas. For this purpose, pedestrain and vehicle occupancy indicators on residential areas are proposed, and vehicle, pedestrain flow and status of on-street parking on residential streets are analyzed. Also, according to the suggested occupancy indicator, occupancy status of pedestrain and vehicle are identified. At the end, evaluation of residential streets are conducted. The suggested occupancy indicator is a quantitative indicator which can represent the traffic situation on street. It can also be represente din the same dimension among pedestrain, vehicle flow, packed vehicle. Also, occupancy indicator can be utilized for the allocation and evaluation of transportation modes on residential street. Except on-street parking during the day time, moving vehicle occupancy rate contains the more than 80 precent when it is estimated based on the vehicle flow and pedestrain only. As the streets on residential area are occupied by the pedestrain approximately 20 percent during the day time, it is identified quantitatively that the necessity of space for pedestrain.
