  • Mobile IPv6 (MIPv6) is a host-based protocol supporting global mobility while Proxy Mobile IPv6 (PMIPv6) is a network-based protocol supporting localized mobility. This paper makes its focus on how to reduce the longer delay and extra cost arising from the combination of authentication, authorization and accounting (AAA) and PMIPv6 further. Firstly, a novel authentication scheme (Proxy-AAA) is proposed, which supports fast handover mode and forwarding mode between different local mobility anchors (LMAs). Secondly, a cost analysis model is established based on Proxy-AAA. From the theoretical analysis, it could be noted that the cost is affected by average arrival rate and residence time.

  • The purpose of this study was to understand the lived experiences of grandmothers and family in transition. Grandmothers in transition means grandmothers who had married children at least one even if there are no grandchildren yet. The data for this study came from 20 grandmothers in transition of 5 focus group(each 4 persons) interview. 9 of them was pre-grandmother without grandchildren yet, 11 was grandmother who had grandchildren. The result of this study revealed that the meaning of grandmotherhood. Dynamics of family in transition around supporting child care represent change of family relations. It didn't means 'empty-nest' model of foreign theory. The Absolute quantity of intergeneral exchange and conflict extended as three generational families.

  • Blast resistant gates are required to be lightweight and able to mitigate extreme loading effect. This may be achieved through innovative design of a gate and its supporting frame. The first is well covered in literature while the latter is often overlooked. The design of supporting frame depends mainly on the boundary conditions and corresponding reaction forces. The later states the novelty and the aim of this paper, namely, the analysis of reaction forces in supporting structure of rectangular steel gates subjected to "far-field explosions". Flat steel plate was used as simplified gate structure, since the focus was on reaction forces rather than behaviour of gate itself. The analyses include both static and dynamic cases using analytical and numerical methods to emphasize the difference between both approaches, and provide some practical hints for engineers. The comprehensive study of reaction forces presented here, cover four different boundary conditions and three length to width ratios. Moreover, the effect of explosive charge and stand-off distance on reaction forces was also covered. The analyses presented can be used for a future design of a possible "blast absorbing supporting frame" which will increase the absorbing properties of the gate. This in return, may lead to lighter and more operational blast resistant gates.

  • Global sourcing refers to activities performed to acquire materials, finished products and apparel production all around the world. The purposes of the study were to examine basic job requirements and primary skills of sales team and supporting team in global sourcing companies, to investigate educational programs provided by the companies or other educational institutions, and to examine courses to be newly established in the curriculum of clothing and textile majors. The results of the study found that the ability to use English and communication skills were important to perform their tasks (sales and supporting teams). The results revealed that fabric and textile, sewing, and apparel production process were the most frequently taken educational programs provided by global sourcing companies and English classes were the most frequently taken educational programs in the other educational institutions. The results also found that the clothing and textile curriculum need to add classes that help sales and supporting teams perform global sourcing tasks, such as fashion practical English, fabric and textile, apparel production processes, textile and apparel trades, fiber and fabric testing, and presentation skills. The study suggested educational directions for developing curriculum contents of clothing and textiles and cultivating professionals in the global sourcing industries.

  • Objectives: The goal of this paper is to examine the social network effects on post-traumatic sdress disorder (PTSD) in female North Korean immigrants who entered South Korea in 2007. Specifically, it attempts to verify if the density and composition of networks make a difference after controlling for the network size. Methods: A multivariate logistic regression is used to probe the effects of social networks using the North Korean Immigrant Panel data set. Because the data set had only completed its initial survey when this paper was written, the analysis was cross-sectional. Results: The size of the support networks was systematically related to PTSD. Female North Korean immigrants with more supporting ties were less likely to develop PTSD, even after controlling for other risk factors (odds-ratio for one more tie was 0.8). However, once we control for the size of the network, neither the density nor the composition of the networks remains statistically significant. Conclusions: The prevalence of the PTSD among female North Korean immigrants is alarmingly high, and regardless of the characteristics of supporting network members, the size of the supporting networks provides substantial protection. This implies that a simple strategy that focuses on increasing the number of supporting ties will be effective among North Korean immigrants who entered South Korea in recent years.

  • The purpose of this study is to evaluate the effect of three different oblique mechanical loading to occlusal surfaces of posterior implant partial dentures on the stress distributions in surrounding bone, using 3-dimensional finite element method. A 3-dimensional finite element model of a posterior implant partial dentures composed of three unit implants, simplified 3 gold alloy crown and supporting bone was developed according to the design of AVANA self tapping implant for this study. Three kinds of surface distributed oblique loads(300 N) are applied to following occlusal surfaces in the three crowns; 1) All occlusal surfaces in the three crown(load of 300 N was shared to three crown), 2) Occlusal surface of centered crown (load of 300 N was applied to a centered crown), 3) Occlusal surface of proximal crown(load of 300 N was applied to a distal proximal crown). In the results, 141 MPa of maximum von Mises stress was calculated at third loading condition and 98 MPa of minimum von Mises stress was calculated at first loading condition. From the results, location and type of occlusive loading conditions are important for the safety of supporting bone.

  • Subcontractors have an increased risk of accidents compared to large contractors. Subcontractors' safety management system is in close association with workers in construction sites. Contractors should strengthen subcontractors' roll and responsibility and provide continual support to prevent an accident. And also these supporting system should be provided to subcontractors' headquarters as well as construction site. Contractors' priority management for subcontractors safety should be transferred from the post management for disciplinary action to the preventive management to improve subcontractors participation and safety performance. Subcontractors can not establish the safety management system with just a one time supporting only. Contractors support and monitoring should be provided to subcontractors regularly and continuously to establish their self safety management system. The subcontractors safety management system improvement program(SSMSIP) suggested in this study will be a effective supporting system for subcontractors to establish and improve their safety management system. If we carry out the objective and quantitative evaluations and supporting system such as SSMSIP and provide the consequential incentive program to subcontractors, it can contribute to the accident reduction.

  • The objective of this study is to prioritize the Total Quality Management (TQM) factors based on fuzzy Analytical Hierarchy Process (AHP) method in Vietnamese supporting industries. Through an in-depth literature review, eight criteria were identified. These criteria were then divided into 32 sub-criteria. The fuzzy AHP is used to determine the percent weightings of eight categories of performance criteria that were identified via a review of the quality-management literature. These criteria include management commitment, role of the quality department, training and education, continuous improvement, quality policies, quality data and reporting, communication to improve quality, and customer satisfaction orientation. An empirical analysis of the criteria of each stage using the fuzzy AHP methodology and the expert opinion of quality management are used to evaluate the percent weightings of the criteria and sub-criteria that are synonymous with TQM implementation. The results showed that management commitment is the most critical factor; among sub-criteria, supports and responsibilities of top management is the most important. The study also identified the rank order of critical success factors of TQM. The findings suggest a generic hierarchy model for organizations to prioritize the critical factors and formulate strategies for implementing TQM in supporting industries, as well as other industries in Vietnam.

  • Constructing substructures by using Top-Down or Downward method needs an efficient formwork system because of difficulties in supporting concrete slabs from the bottom while excavation is in process. Existing underground formwork systems can be classified by three types: graded ground supported type (Slab On Grade, Beam On Grade), suspension type (Non Supporting Top Down Method), and bracket supported type (Bracket Supported R/C Downward). Each method has its own advantages and limits. Application of a specific formwork system for a given construction site is determined by various conditions and affect construction time and cost. This paper presents a newly developed underground non-supporting formwork system, which combines the advantages of a suspension type and a bracket supported type while it overcomes limits of two types. The developed system has a moving formwork which is supported by suspension cables hanging from the bracket placed at the top of pre-installed substructure columns. Then, the moving formwork is repeatedly lowered down for the next floor below to support concrete slab during curing. The details of this bracket and cable supported system have been investigated for the improvement of easiness in construction.
