An experimental study was carried out to estimate development lengths of the prestressing strand in pretensioned beams. Recent studies had indicated that current desing provision were inadequate. Objective of this investigation is to determine the effect of strand diameter and concrete cover in pretensioned beams. Strand of the 1.52cm diameter is more useful and economic than that of the 12.7mm diameter, but current provision does not include 15.2mm diameter strand in experimental data. Because the property of strand has been developed, current provision need to be improved. Based on the experimental data, it was determined that bond failure would be prevented if no cracking occured in transfer zone of a pretensioned strand.

The evolution of EDI has opened the flexible and efficient way for business to conduct a greater portion of the routine buyer-seller business activities online. This study focuses on the role of factors that change the innovation characteristics for implementation success of EDI. Three factors promotional efforts, proactive implementation strategy, and provision of technical expertise are proposed to affect EDI implementation success, as these factors directly influence three general and most important attributes of innovation relative advantage, compatibility, and complexity respectively. Hypotheses indicate that promotional efforts, proactive implementation strategy, and provision of technical expertise directly affect EDI implementation success that is represented by three variables volume, depth, and diversity. A structural equation modeling approach(LISREL) is used to analyze data from EDI adopters. The results show that proactive implementation strategy and provision of technical expertise positively affect implementation success of EDI. Given the significant impact of the wide spread use of the EDI system, this study offers quite useful insights on the factors facilitating innovation characteristics under which EDI can be successfully diffused in organizations.

Effective traffic matrix estimation is the basis of efficient traffic engineering, and therefore, quality of service provision support in IP networks. In this study, traffic matrix estimation is investigated in IP networks and an Elman neural network-based traffic matrix inference (ENNTMI) method is proposed. In ENNTMI, the conventional Elman neural network is modified to capture the spatio-temporal correlations and the time-varying property, and certain side information is introduced to help estimate traffic matrix in a network accurately. The regular parameter is further introduced into the optimal equation. Thus, the highly ill-posed nature of traffic matrix estimation is overcome effectively and efficiently.

Objective : The purpose of this paper is to report the improvement of patient with dizziness treated by herb medication based on Shanghanlun disease pattern identification diagnostic system. Methods : According to 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions', the patient diagnosed with Taeyang-byung, number 27 provision, and took Guizhieryuebiyi-tang herb medication 30 days. The changing symptom of dizziness was estimated by VAS(Visual Analogue Scale). Results : The VAS changed 10 to 0. Conclusions : On the number 27 provision of Shanghanlun, '弱' means lower body helplessness. This is the first case report treating the dizziness with Guizhieryuebiyi-tang in Korea.

Objective : The purpose of this paper is to report the improvement of patient with pitting edema treated by herb medication based on Shanghanlun disease pattern identification diagnostic system. Methods : According to 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions', the patient was diagnosed with Taeyang-byung, number 96 provision, and took Soshiho-tang herb medication 30days. The changing symptom of pitting edema is reported depended on the edema scale and the statement of patient during treatment. Results : The pitting edema of patient disappeared by 96 provision of Soshiho-tang seclected according to Shanghanlun provisions. Conclusions : This case report suggests that two words on the 96 provision of Shanghanlun, '或 心下悸, 小便不利'(palpitations below the heart, inhibited urination) indcate close relationship between palpitation and decrease of genital secretions, which affected the edema in this case.

Despite the growing interest in technostress phenomenon of employees in organizations, few guidelines exist about how mangers can effectively control their technostress. Accordingly, scholars should pay greater attention to how firms can successfully manage employees' technostress. This study conceptually developed and tested a research model for understanding the influence of technostress on psychological and behavioral strains. In addition, we tested technical support provision as a moderator. We obtained 107 samples through a survey questionnaire, and data were analyzed based on structural equation modeling (SEM). As a result, it was empirically demonstrated technostress decreases job satisfaction and individual productivity. We also found that technical support provision have moderating effects on the relationship of technostress and job satisfaction/individual productivity.

This study was conducted to compare and analyze the management status of internet homepage of catering companies in Korea for improving internet marketing. An evaluation tool with 6 categories consisting of contents, information update, user's convenience, design, provision of related information, and accessibility was developed and used for the analysis of 6 major catering companies. A five-point likert scale (1=very badly organized, 5=very well organized) was used for evaluating above six categories. The overall mean score for six categories was 2.91 out of 5, showing below the average. The categories received less than 3 points were information update (2.16), user's convenience (2.33), and provision of related information (2.83). The scores for design was the highest (3.66), followed by accessibility (3.33), and contents (3.16). These results suggest that the internet homepaee of the catering companies should be improved especially in the provision of enough information and its update in order to promote their internet marketing.

Towards the deployment of 3rd generation systems, Virtual Home Environment (VHE), stemming from 3GPP, appears to be a powerful concept advocating the provision and delivery of personalized services to roaming users across network and terminal boundaries. This paper aims to expose the pathway for materializing the VHE concept, via the specification, implementation and evaluation of a prototype. Core aspects for realizing the concept such as the business and roaming models are presented, while a VHE enabling architecture utilizing key technologies (OSA/Parlay, MExE, and USAT) is introduced. The proposed architecture has already been evaluated by performing an initial trial demonstration. Currently it is being extended to support VHE service provision to roaming users, an aspect to be addressed by the final trial.

This paper examines the achievements and limitations of housing assistance programs for low-income households. Korean public rental housing has been rapidly developing since 2000, and thereby achieved an increase in public rental housing stock, housing quality improvements, and the reduction of rent over-burden for low-income tenants. Despite some conflicting evidence, it appears that the provision of newly-built public rental housing has helped stabilize the prices of neighboring private rental housing units. But, as we are entering an era of one million long-term public rental housing units, we need to shift our focus from quantity-oriented provision to housing maintenance for tenants, and from cost-based rental housing to affordable rental housing and better access to rental housing for low-income tenants who are not beneficiaries of government assistance. Most of all, it is very important for local governments and the private sector to actively participate in the provision of public rental housing in order to ensure a stable rental housing market.

After the reform of rail industry, a system to evaluate service qualities is required for the continuous improvement of railway service and the strength of competitiveness. This research provides evaluation categories and indices which are considered to be suited to the evaluation of rail service qualities. This study provides 4 categories and 11 indices to assess the rail service qualities: provision-operation interval/average operation speed, reliability-regularity/operation cancellation rate, safety- train usage term/facilities for the weak, client satisfaction- easiness of reserving and purchasing of tickets/comfort of queuing facilities/ kindness of train crews/ pleasantness of trains/provision of information, etc.
