A cloud computing service provider must assure Service Level Agreement (SLA) to provide reliable and consistent quality of service to a user. The SLA is a contract between the user and the service provider that connects to assure constant level such as availability to target provided service. The cloud computing is classified into IaaS, PaaS, and SaaS according to IT resources of the various cloud service. The existing SLA is difficult to reflect quality factors of service because it only considers factors about the physical Network environment. In this paper, we suggest the UDDI-based interchange process with the architecture and the specification language having a XML schema for the SLA specification. The quality requirements of SaaS are defined by a proposed specification language in the cloud environment. It is stored in the repository of a quality specification and exchanged on during the service binding time based on the exchange architecture.

Gyeongju bentonite is a buffer material primarily considered in Korea and it is highly compacted as a part of an engineered barrier system (EBS) of high-level radioactive waste repository. The compacted bentonite undergoes swelling stress by groundwater penetration and thermal stress by decay heat from a canister. Therefore, the mechanical properties of the compacted bentonite buffer material is crucial for the performance assessment of EBS. This paper aims to evaluate deformation properties of Gyeongju compacted bentonite using seismic methods. Two sets of compacted bentonite specimens were prepared having dry densities of $1.59g/cm^3$ and $1.75g/cm^3$ with water contents of 10.6% and 8.7%. Free-free resonant column tests were performed to measure constrained and unconstrained compression wave velocities. With the measured wave velocities, Young's modulus ($E_{max}$) and constrained modulus ($M_{max}$), material damping ratio ($D_{min}$), and Poisson's ratio at small strain were determined. As results, this paper evaluates the deformation properties of Gyeongju compacted bentonite and compares them with the results of previous researches.

This study is intended to examine the existing condition of records and archives management and seek its improvement and progress on a concrete model of Daejon Diocese as a kind of case study, because it is necessary to recognize the importance of records and archives management and to develop the records and archives management system. Daejon Diocese which has the catholic jurisdiction covering the areas of Daejon city and Chung Cheong Nam - Do province, celebrated the 40th anniversary of the diocese in 1998. At that, time, the authority of Daejon Diocese claimed to establish its church history institution and to plan the publication of "40 years history of Daejon Diocese". However, its publication could not be achieved until now for several reasons. Since my search for the cause of this situation, I immediately recognized that the lack of materials might be a common condition in almost all of the associations, especially with respect to management, preservation and access of the records and archives. The records in the archival repository of Daejon Diocese have been considerably lost because of the past intemperate destruction and these records have just piled for long time without any reasonable disposal programme. Therefore, in these poor conditions, it is inevitable to delay the publication of "40 years history of Daejon Diocese." This thesis deals with the archival arrangement and the ways of improvement by means of studying the records and archives management, as the essential issues. The archival arrangement based on the principle of provenance, the date of creation, and form division. The methods of improvement include the preservation environment, the scope of archives, archival staff, disposal and so on. Records have the legal and social value after being produced and they can remain as historical and cultural inheritances under the excellent condition of management and preservation. However, in examining the case of the management and preservation of records and archives in Daejon Diocese, I understand that it will need considerable time, man power, and financial cost in order to maintain the desirable level of records and archives management system Therefore, it is a important step for Catholic Daejon to recognize the necessity of the change over records and archives management.

Eumsikjeoljo (integrity with food) originally came from the Andong district, where the Goseong Yi clan inherited a cookbook from their ancestor Lee Jeong-Rong (1798~1871). The cookbook was written in an antiquated style and is estimated to have been written around the year 1865. Details of the era and authorship are seldom available for the extant ancient cookbooks. The authors of these books and the period during which these books were precisely written were studied through the Eumsikjeoljo which is a repository of 46 cooking disciplines. Of these 10 deal with the practice of traditional Korean crispy snack making, 4 with rice cake making, 3 of the yeonbyeong kind, 19 examples of Korean side dish making, 6 recipes of the kimchi variety, 2 examples of paste-based recipes, and 2 instances of instructions on how to make vinegar-based extracts. Also, in Eumsikjeoljo, there are descriptions of 29 different ways to brew rice wine. Of these, Danyang wine among the Leehwa wines and 13 others account for over 44% of the content. Leeyang wine and Sogok wine are represented by 10 different varieties and constitute around 34% of the entries. Samyang wine and Baek-il wine, along with 6 others, constitute 21% of the entries. The secret recipes of the Goseong Yi clan in the Andong district were recorded so that they could be transferred to the descendants of the clan. An inspection of the recipes and wine brewing techniques recorded in Eumsikjeoljo provides a clearer picture of the mid-1800s Andong noble family's traditional food habits and simultaneously sheds light on the late Joseon dynasty's food culture.

This study aims to investigate bibliometric services practices of foreign libraries by service types and suggest practical considerations for Korean libraries wishing to implement bibliometric services. Through the examination of previous research and library websites, nine types of bibliometric services were identified under two broad categories - education & consulting services and research evaluation & research trend services. According to the service types, a wide range of bibliometric services activities were analyzed and described. Recommendations from the study for service development include: building an institutional repository for scholarly output; developing subject guides and education programs at the initial phase of service and providing more advanced services such as consulting and analysis services at the later phase; identifying the potential service needs of researcher groups.

In order to provide the efficient personalized services, the organizations and the companies collect and manage the personal information. However, there have been increasing privacy concerns since the personal information might be misused and spread over in public by the database administrators or the information users. Even in the systems in which organizations or companies control access to personal information according to their access policy in order to protect personal information, it is not easy to fully reflect the information subjects' intention on the access control to their own Personal information. This paper proposes a policy-based access control mechanism for the personal information which prevents unauthorized information users from illegally accessing the personal information and enables the information subjects to control access over their own information. In the proposed mechanism, the individuals' personal information which is encrypted with different keys is stored into the directory repository. For the access control, information subjects set up their own access control policy for their personal information and the policies are used to provide legal information users with the access keys.

Mobile Ad-hoc networks have various implementation constraints such as infrastructure-free, no trusted authority, node mobility, and the limited power and small memory of mobile device. And just like wired networks, various security issues such as authentication, confidentiality, integrity, non-repudiation, access control, availability and so on have been arisen in mobile Ad-hoc networks. But we focus on authentication of these security issues because it is quitely affected by the characteristics of networks. In this paper, we propose the authentication protocol that can limit the size of certificate repository as $log_2N$ and assures to make a trusted certificate path from one node to another, adopting the concept of Hamming distance. Particularly, our protocol can construct a trusted certificate path in spite of decreasing or increasing the number of nodes in mobile Ad-hoc network.

Objectives: Many conditions of the oral and maxillofacial region require hospitalization and in-patient care. The average length of stay (LOS) of these patients varies and is usually affected by multiple confounding variables. However, even with an increasing number of hospital admissions, published evidence on the factors that affect the LOS of oral and maxillofacial patients is lacking. Therefore, this study assessed the LOS of in-patients at the oral and maxillofacial surgery department of a government-funded, multi-specialty hospital in Malaysia, based on their reasons for admission and other factors. Materials and Methods: Our samples were collected retrospectively over a 5-year period and included patients with maxillofacial infections, post-trauma stabilization, facial bone fracture surgery, benign and malignant lesion surgery, dentoalveolar surgery, and other maxillofacial surgeries as reasons for admission. Factors potentially affecting LOS were also recorded, and their significance was determined using multiple logistic regression analyses. A P-value of less than 0.05 was considered to be statistically significant. Results: A total of 1,380 patients were included in this study. Most (84.5%) of our in-patients were of Malay ethnicity, and males outnumbered females in our sample by 502 subjects. The median LOS of our in-patients was 3 days. Sex, ethnicity, age, reason for admission, and American Society of Anesthesiology (ASA) classification were factors that significantly affected LOS. Conclusion: The median LOS reported in this study was 3 days. LOS was significantly affected by sex, ethnicity, age, reason of admission and ASA classification.
