An Ad hoc network, differently from wired networks, is a self organized network of mobile nodes in wireless environments. In this kind of routing and operation environments. link breaks occur frequently. Knowing positions of nodes may prevent or recover this type of phenomenon. Typically, GPS is used to detect position of nodes but high cost and complexity of construction limit applications. In this paper, we propose and design a method of construction nodes' position map using only information of all nodes without GPS. The proposed method complements and overcomes previous system with software solutions. Hence, construction and operation are simple, and can decrease cost of construction expenses.

A pipe jacking method complements the excavation method and it is a non-excavation method which is thrust in the earth. On that score, using the pipe jacking method is increased because of constructability and economical efficiency in a medium or small-sized pipeline construction. However, a pipe jacking method still has several problems that the base ground is disturbed and loosen. Especially, where some sites have boulders, gravels and foreign bodies, the foundation is brought about deformation, settlement and leakage of water. Thus, the end of the construction the ground should be reinforced by grouting and it occur with additional expenses. Therefore, a steel pipe jacking method with grouting, Grout In Pipe, is devised newly to complement the existing method. In this study, it describes a new method and verifies efficiency, an application and practicality of the method through a experimental construction.

A 4-story reinforced concrete structure built above an underground parking garage shows some slab deflections, and the deflections of the concrete floor slabs are proposed to be alleviated by the application of light-weight topping material in conjunction with localized strengthening of the slabs. The application of light-weight concrete topping on the existing slab has been simulated and its performance to anticipated loads has been analyzed. The application of light-weight topping material imposes additional weight on the exiting floor slabs. This added weight on the existing slabs causes over-stressing of the slabs. This over-stressing can be alleviated by enhancing the load carrying capacity of the existing slabs. Additional load carrying capacity in the existing slabs can be developed by localized strengthening of the slabs utilizing techniques such as the application of fiber-reinforced composites on the bottom surface of the slabs, and application of fiber-reinforced composites adequately complements the capacity of the existing slabs to bear the additional load imposed by light-weight leveling material. Additional moments in the beam and columns induced by the application of the light-weight topping material were tabulated and compared with capacity. The moment D/C ratios of the beam and columns are well the range of acceptable limits, and the beam and columns are not overstressed by the application of the surcharge.

As popularity of dental implantation is increasing, the number of cases associated with complications also increase. Evaluation on diabetes mellitus is often neglected due to the disease's irrelevance to implantability. However, patients with diabetes mellitus are susceptible to infection due to impaired bactericidal ability of neutrophils, cellular immunity and activity of complements. Due to this established connection between diabetes mellitus and infection, a couple of cases were selected to present patients with diabetes mellitus with glycemic incontrollability, suffering from post-implantation dentigerous inter-fascial space abscess.

This research was performed to be used as basic data for educational program development related to smoking prohibition guidance by fording out the relevance among variables of dental hygienists' knowledge, attitude and practice on the smoking prohibition guidance. The formalized research paper which had been used to nurses was revised with a few complements and accomplished through a visit. Both-test and dispersion analyses were performed and a post test was followed. Relevance analysis was fulfilled for the relevance among the variables and the research results are as followed. 1. Likert 3 and grade 2.14 in the knowledge on smoking prohibition guidance of dental hygienists; These results are statistically similar since the higher academic careers are based, the higher grades are obtained. 2. Likert 5 and grade 3.14 in the attitude on hygienists' smoking prohibition guidance activities. 3. High awareness on the importance of non-smoking in case there is no smoker among family. 4. Likert 5 and grade 3.16 in the practice of smoking prohibition guidance activities. 5. Similar relevance among the knowledge, attitude and practice; the higher knowledge, the more positive attitude and the more positive attitude, the more practice.

Purpose: The purpose of this study was to analyze and estimate whether each company may produce the color of artificial teeth as it stands, in the standard of vita classical shade guide using ShadeScan$^{TM}$ System. Material and methods: we chose the products of 6 companies -EFUCERA, IVOCLAR, ENDURA, TRUBYTE, DURADENT, and DURACROSS- estimated the shade value of each fixed point(cervical, body, and incisal area) of artificial tooth, and verified the equality among the samples from the same company. Results: First, the variation appeared significant at cervical and incisal area. It means that there were significant differences between cervical and incisal area although the most similar artificial teeth to the patients’natural teeth were provided. Second, the results in the body area showed that the variation between artificial and natural teeth was finite(p<0.05) in that area. Conclusion: it shows that the reproduction of colors of artificial teeth might be successful regarding the body is the most important part for a determination of the color of artificial teeth. However, more complements are necessary for the better reproduction of the color of artificial teeth between cervical and incisal area.

This paper explored the marriage migrant mothers' experiences of parenting bi-ethnic children in South Korea based on the concepts of ethnic socialization and intersectionality. We analyzed in-depth interviews of 22 marriage migrant women from Vietnam residing in the capital region of South Korea. They had at least one child whose biological father is Korean. Children were 5 years old or older, attending preschool or elementary school. Five types of bi-ethnic socialization strategies were identified, which provide portraits of different situations in which marriage migrant women were placed. The five strategies that emerged from the data were 1) "Natural practice of bi-ethnic socialization" including two heterogeneous groups, "Coexistence of two cultures" and "Mixture of two cultures", 2) "Active practice of bi-ethnic socialization", 3) "Struggling practice of bi-ethnic socialization", 4) "Silence on bi-ethnic socialization", and 5) "Suppressed bi-ethnic socialization". The strategies of bi-ethnic socialization that marriage migrant women chose to raise their children reflected personal perceptions of Korean society and individual ethnic identity formed within Korean society. This study complements existing research on ethnic socialization by examining how ethnic socialization practices are shaped by multiple contexts marriage migrant women embedded in Korean society.

In the real world, business processes are very complex and composed or heterogeneous business activities. As the advent or the Web services enables business processes to be Integrated and to be automated. It makes enterprises integrate heterogeneous business processes from different business partners as well as their internal business processes. To support recent trends in integration of business processes, BPEL, WS-E and WS-T specipications have been established since 2002 WS-C and WS-T describe the reliable business environment including compensation (undo) or completed business processes. The compensation of business processes is a basic requirement for automation or business processes among business partners. Systems implementing these specifications, however, very rarely exist. It's not only because those specifications are developed recently. but also because they are not perfect yet. In this paper, a new business process transaction management, which complements the deficiency of WS-E and WS-T, is suggested. Furthermore, the new approach proposes the business logics for supervisory coordinators which manage serial and parallel business gates The modification or traditional WS-T specification and the simplification or WS-E specification make business processes managed effectively.
