  • Background: Cholangiocarcinoma (CCA) is the most common cancer in Northeast Thailand. It is also a crucial health problem for Thai people. Various risk factors for CCA have been identified in the upper part of Northeast Thailand, but no similar studies of risk factors have been conducted in the lower parts of the region. This study aimed to investigate factors associated with CCA in the resident population. Materials and Methods: A hospital-based case-control study was conducted during 2009-2012 with the recruitment of 123 CCA cases and 123 non-CCA patient controls, matched for sex, age and residential area. Information was collected by interview with a structured questionnaire. Blood samples were collected for assays of anti-OV antibodies. Associations between various personal factors, dietary habits, family history, the presence of anti-OV antibodies and CCA were analyzed using multiple conditional logistic regression. Results: Patients who consumed raw meat (beef, pork) and alcoholic beverages ${\geq}3$ times per week had a higher risk of CCA than non-consumers ($OR_{adj}$=4.33; 95%CI=1.14-16.35 and $OR_{adj}$=2.13; 95%CI=1.00-4.55, respectively). Patients who had a family history of cancer had a higher risk than those who did not ($OR_{adj}$=4.34; 95%CI=1.80-10.43). Also, patients who had anti-OV antibodies (AU>23.337) had a higher risk than those whose anti-OV antibodies were below the cut-off ($AU{\leq}23.34$) ($OR_{adj}$=3.09; 95%CI=1.04-9.16). Conclusions: As is the case in the upper part of Northeast Thailand, OV infection is a crucial risk factor for CCA in people who live in lower part of the region. Similarly, a family history of cancer and the consumption of alcohol are risk factors for CCA.

  • The intraclass correlation model has a long history of applications in several fields of research. Case deletion diagnostic methods for the intraclass correlation model are proposed. Based on the likelihood equations, we derive a formula for a case deletion diagnostic method which enables us to investigate the influence of observations on the maximum likelihood estimates of the model parameters. Using the Taylor series expansion we develop an approximation to the likelihood distance. Numerical examples are provided for illustration.

  • The local history research started from the 1960's postmodernism neted in the local history as the subject of diversity instead of National history. The local is being magnified as a new research theme among history scholar. In these circumstances, the local history research shows sign of activity and the movement that used in various ways at education has become more active. Compared to the contents business of local history, development of education contents what serviced for student is insufficient. Therefore, this research suggests development plan of local history education contents using archives which efficient tool of history education. Students can grow the ability of historical inquiry, thinking, insight through archives-assisted learning. Also, self-learning is possible instead of a lecture by teacher. This research shows a development of archival contents for local history education though literature research, abroad case analysis, focus group interview with history teachers. Concepts of the local history, local history education, education contents are examined at literature research. Local history education of the State Archives of the United States of America, the United Kingdom, Australia web site is analyzed. These state archives have been providing the web based service of archival contents for local history education for a long time. With these theoretical background, carry out a focus group interview with middle school history teachers. It draw conclusion that 14 category and 35 subcategory and these are reflected in the development of archival contents for local history education.

  • Branch prediction accuracy is critical for system performance in modern microprocessor architectures. The use of speculative update branch history provides substantial accuracy improvement in branch prediction. However, speculative update branch history is the information about uncommitted branch instruction and thus it may hurts program correctness, in case of miss-speculative execution. Therefore, speculative update branch history requires suitable recovery mechanisms to provide program correctness as well as performance improvement. In this paper, we propose recovery logics for speculative update branch history. The proposed solutions are recovery logics for both global history and local history. In simulation results, our solution provides performance improvement up to 5.64%. In addition, it guarantees the program correctness and almost 90% of additional hardware overhead is reduced, compared to previous works.

  • Purpose : Local medicinal herb festivals present the history of the Korean medicine and cultural resources in the regions to play an important role in attracting tourists, vitalizing local economy, and improving the local image. Therefore, it is important to understand the origin of the festival and grasp historical and cultural meaning of local medicinal herb festivals. Methods : I compared the books and articles presented in the reference list. Results & Conclusions : Local medicinal herb festivals originates from traditional yangnyeongsi. Since the $17^{th}$ century, yangnyeongsi has grown up as a special market. Implementation of the Daedong Act promoted commodity and monetary economy that helped commerce and industry develop and market grow up. It also made changes in the social status system and yangnyeongsi has been such a historical phenomenon appeared in this social background. The growth of yangnyeongsi contributed to the progress in the private medicine that triggered the gradual transfer of power in the medicine to the private sector which has long been held by the government. In yangnyeongsi, there were many cultural events to attract visitors. It's the same case in China that preserves stages that were used for cultural events in the medicine market to pass down the historic sites while those in Korea are disappearing as yangnyeongsis are being pulled out of the city areas to the suburban areas due to the redevelopment projects. For this reason, restoration of the place for traditional yangnyeongsi should be taken into account through local medicinal herb festivals.

  • The servicescape of a design hotel means the physical environment in which a service is produced and consumed. Servicescape refers to the comprehensive physical environment perceived by users and is composed of physical elements such as ambient conditions, space, function, signs, symbols and artifacts. For a successful operation of a design hotel, it is necessary to investigate the design hotel's servicescape types according to characteristics of design hotel's servicescape to provide various servicescape. The purpose of this study is to classify the types of servicescape on design hotel and analyze characteristics through the case study. A case study on Europe's design hotels to find various servicescape design methods was conducted. According to characteristics of design hotel the types, it is also categorized into four different types: history/tradition, art/culture, collaboration, locality. The case study demonstrated that European design hotels were making many efforts for their uniqueness and differentiation by considering the cultural and historical characteristics of their city and providing art and cultural space for their community. Design hotels in Korea should not only provide visitors with opportunities to have special experience through the nation's own culture and history but also serve as a place of community activities.

  • This study is a case study of system improvement measures for urban regeneration of the historical and cultural environment. The example areas are Hwangnam and Inwang Hanok districts in Gyeongju City, which operate various systems to solve the urban decline problem caused by the historical and cultural environment regulations. The subjects of this study are resident support programs and district unit planning systems under the advanced promotion system established in the case area. As research methods, literature studies, field surveys, and in-depth interviews were conducted. Through this, the background and purpose of introduction of each system, major plan contents, and problems of the system application process were analyzed. This study drew the following implications through case studies. First, in order to more effectively promote the urban regeneration of the historical and cultural environment, it is necessary to improve the related systems in an integrated and systematic manner. Second, in order to resolve the policy distrust of local residents in the historical, cultural and environmental management system, a wider variety of planned alternatives to narrow the difference in interests between the public and private sectors should be presented.

  • Although lipoma is a common benign tumor, it occurs relatively infrequently in the oral and maxillofacial areas, and only 31 cases of lipoma in the buccal fat pad have been reported. Herein, we present an extremely rare case of symmetric lipomas in both buccal fat pads. These masses were incidentally discovered during a facelift procedure in a 50-year-old woman with a 4-year history of tamoxifen use. during which she had gained 10 kg. The patient stated that cheek protrusion had developed concomitantly with weight gain and was exacerbated by an injection lipolysis procedure she had received 1 year previously. This case underscores the importance of paying careful attention to the patient's medication use and surgical history when evaluating suspected cases of lipoma, and sheds light on tamoxifen use and subcutaneous injections of phosphatidylcholine and deoxycholate as potential risk factors for lipoma development.

  • This study aims to investigate the evolution of calculating the volume of a sphere in eastern and western mathematical history. In western case, Archimedes', Cavalieri's and Kepler's approaches, and in eastern case, Nine Chapters';, Liu Hui's and Zus' approaches are worthy of noting. The common idea of most of these approaches is the infinitesimal concept corresponding to Cavalieri's or Liu-Zu's principle which would developed to the basic idea of Calculus. So this study proposes an alternative to organization of math-textbooks or instructional procedures for teaching the volume of a sphere based on the principle.

  • Early detection and treatment decrease the mortality rate associated with gastric cancer (GC). However, the natural history of GC remains unclear. An 85-year-old woman was referred to our hospital for evaluation of a gastric tumor. Esophagogastroduodenoscopy identified a 6 mm, flat-elevated lesion at the lesser curvature of the antrum. A biopsy specimen showed a well-differentiated tubular adenocarcinoma. The depth of the lesion was estimated to be intramucosal. Although the lesion met the indications for endoscopic resection, periodic endoscopic follow-up was performed due to the patient's advanced age and comorbidities. The mucosal GC invaded into the submucosa 3 years later, and finally progressed to advanced cancer 5 years after the initial examination. The patient died of tumor hemorrhage 6.4 years after the initial examination. In this case, mucosal GC progressed to advanced GC, eventually leading to the patient's death from GC. Early and appropriate treatment is required to prevent GC-related death.
