This study showed a way to develop web site of shopping mall through systematic identification of the interface elements affecting user's performance and subjective sensibility for Internet shopping mall. To quantify the effects of factors, simulators were designed and used in experiments. It was shown that location of 'Table of Contents'(left > right = up = down) and 'Menu' type(non_Drop down and page Movement = Drop down and page Movement > Drop down and non_age Movement) were the significant factors. However, whether 'Frame' was used or not, there was no significant difference. Also, in the evaluation of subjective sensibility, 'Background color' was a significant factor. And for 'Header & Scanning Column color', yellow color had a tendency to enhance satisfaction for 'simplicity', while green or blue color strengthened 'balance' feeling. But 'text style' was not significant.

There is a problem to be solved for improvement of durability and safety for concrete When the waterproofing and anticorrosive work of main concrete are design, the material a of construction need to be correctly applied to appropriate circumstance conditions. Epoxy mostly been used for concrete water tank structure. Lately, lots of subjects on adaption res in mortar for waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with waterproofing materials in this experiment. Capability evaluation items include the bond age and curing conditions, the bond strength after accelerated weathering test and fret impact resistance, a mount of water, seepage quan Through the experiment analysis, we found that waterproofingtity, drinking water chemicals resistance. and anticorrosive resin mortar used with glass fiber cloth, inorgar material is dominantly superior to other waterproofing materials. According to this paper, we suggest the resin mortar as a new surface treatment material water tank structure.

This survey is mainly focus on identifying the efficacy of CPR training for 92 first responders who participated in the first aid and emergency rescue program dated on November 22 and November 24, 2000. First responders are trained and evaluated using AHA guideline for 4 hours. Data are analyzed by Percentage, Mean, T-test, F-test using SPSS program. The results for this study are as follows: 1. An average score for CPR evaluation is high as 1.71 of total score 2.0. 2. Between adult CPR and infant CPR, an average score for adult CPR is higher than infant CPR. The highest item of adult CPR and infant CPR is checking for unresponse(1.95 and 1.93), the lowest items are checking for circulation and chest compression position in the adult CPR and location of chest compression in the infant CPR 3. There are statistically significant differences in the evaluation score of CPR according to age, education level, occupation, job experience and emergency accident situation in the past.

This study examined the conditions and administration of 548 private, social welfare, and elementary school-based facilities providing after-school child care. The School-Age Care Environment Rating Scale developed by authors was administered to the teachers of these facilities. The rating scale consists of 84 items in 9 sub-areas. Seven point ratings were obtained for each item. One-way ANOVA confirmed differences between all items at the (p<.001) except for supplementary special needs items. The private facilities had the best environment for after-school child care except for staff development. The social welfare facilities showed good evaluation in staff-child interactions, activities, staff development and administration. The elementary schools obtained low evaluations except for supplementary special needs items. The evaluation of social welfare facilities was highest in Seoul and private child care facilities were highest in other areas.

Fly ash, has been widely used as one of the main supplementary cementitious materials (SCMs) in the world, to replace part of cement to significantly save energy and reduce greenhouse emission. Via mechanical activation, fly ash can replace more cement without impairing early age compressive strength. This study focuses on the strength-based evaluation of carbon dioxide emission for blended cement composite containing mechanically activated fly ash. Results indicate that under similar compressive strength, a prominent drop has been witnessed in embodied energy of binary cement and CO2 emission of the composite containing mechanically activated fly ash compared with those containing ordinary fly ash.

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.

화자 간 음색의 유사성은 화자 인증 시스템의 성능을 하락 시킬 수 있는 요인이다. 본 논문은 화자 인증 시스템의 일반화 성능을 향상시키기 위해, 심층신경망에 멀티태스크 러닝 기법을 적용시켜 발화자의 화자 정보와 나이 정보를 함께 학습 시키는 기법을 제안한다. 멀티태스크 러닝 기법은 은닉층들이 하나의 태스크에 과적합 되지 않도록 하여 심층신경망의 일반화 성능을 향상시킨다고 알려져 있다. 하지만 심층신경망을 멀티태스크 러닝 기법으로 학습시키는 과정에서, 나이 정보에 대한 학습이 효율적으로 수행되지 않는 것을 실험적으로 확인하였다. 이와 같은 현상을 방지하기 위해, 본 논문에서는 심층신경망의 학습 과정 중 화자 식별과 나이 추정 목적 함수의 가중치를 동적으로 변경 하는 기법을 제안한다. 동일 오류율을 기준으로 RSR2015 평가 데이터세트에 대해 화자 인증 성능을 평가한 결과 나이 정보를 활용하지 않은 화자 인증 시스템의 경우 6.91 %, 나이 정보를 활용한 화자 인증 시스템의 경우 6.77 %, 나이 정보를 활용한 화자 인증 시스템에 가중치 변경 기법을 적용한 경우 4.73 %의 오류율을 확인하였다.
