Purpose: The purpose of this study was to investigate the cognition of denture fabrication activities and its cost in National Health Insurance for elderly denture. Methods: A self-administered questionnaire was completed by 41 dental laboratories' owner who was research subjects of HIRA(Health Insurance Review & Assessment Service)'s policy research for elderly denture in 2011. The questionnaire consisted of general characteristics of the subjects, dental technicians' knowledge of national health insurance coverage of elderly denture, job-related changes after national health insurance coverage of elderly denture including validity of denture fabrication activity classification and the cost for each service. Each question was measured by Likert 5 point scale or frequency. The collected data were analyzed by SPSS 16.0. Results: Most of the research subjects had been fabricating national health insurance coverage denture(92.7%), also had ample knowledge of national health insurance coverage denture for elderly. Job-related changes after national health insurance coverage of elderly denture revealed marginal differences in the quality. The validity of fabrication activity classification of resin based complete denture was $3.71{\pm}1.023$ by Likert 5 point scale. Conclusion: The goal of national health insurance for elderly denture is to promote elderly's health and well-being. To fabricate denture is a very important part of the denture treatment. For this reason, denture fabrication activity classification and the cost analysis plan should be duly reflected in the policy of national health insurance for elderly denture.

The major educational goal of reading part, which occupies important portion in Korean language in Korean SAT, is to evaluated whether a given text can be fully understood. Therefore given questions in the exam must be able to solely solvable by given text. In this paper we developed a datatset based on Korean SAT's reading part in order to evaluate whether a deep learning language model can classify if the given question is true or false, which is a binary classification task in NLP. In result, by applying language model solely according to the passages in the dataset, we were able to acquire better performance than 59.2% in F1 score for human performance in most of language models, that KoELECTRA scored 62.49% in our experiment. Also we proved that structural limit of language models can be eased by adjusting data preprocess.

The Bieniawski's geomechanics classification system(1984) is widely employed as a tool of engineering evaluation of rock masses for tunnel design. Since the siz parameters adoped in the system are believed to control the engineering behavior of rock mass under an external load, no question may be raised to the conceptional idea immanent in the system. However, the rating grade for each individual parameter given in the system may be properly measured since an engineering property of rock mass is not stepwise changed but continuously changed. In order to get the proper rating grade based upon the continuously changed properties in each parameter, several equations presented in this paper are obtained through regration analyses with the grades and median values of properties givne in the system. A FORTRAN computer program given in the paper could provide not only RMR value but also rock mass properties (E, c, o, v, etc.) using the empirical equations.

Class III malocclusions are difficult to treat and take more time than any other types. But if such problems are detected at the earliest opportunity, we may gain the best possible correction consistent with the limitations imposed by morphogenetic pattern. The question of whether a patient has false or real Class III malocclusion is not important. Therapy wilt eleminate the malrelationship, in any event. Graber said, 'It has been my experience that many so-called 'pseudo' Class III's are full-blown Class III's later on during the prolific growth period.' The authors have attempted early treatment of a Class III malocclusion of 8-year old girl, who has the familial history of Class III malocclusion.

This study compares the reasons why Large and Small companies are adopting and realization benefit electronic commerce(e-commerce) based on an assumption of difference between two groups of companies. We collected data for contemporaneous analysis by classification with two groups of companies in Korea and developed an integrated model from the empirical studies and made Question papers for inspection of created hypothesis.

1. Purpose This study has focused on response rates of the questionnaire which considered as a basic data to identify constitution for American. 2. Methods By analysing the tendency of the respondents who has defined constitution by clinical diagnosis and comparing of their answers, the result of their constitution analysis by our questionnaire were re-examed. The answer of each question to each constitution were tested how it is relevent to a scale of a constitution. Each item response rate on SF_SSCQ-A was analysed about those who had been tested and diagnosed as Taeyangin, Soyangin, Taeeumin, Soeumin respectively. 3. Results There were the 55 significant items; 13 Taeyangin items, 13 Soyangin items, 20 Taeeumin items, 9 Soeumin items. However, there were the 11 low response rate items (below 10 %) and 4 no response items.

This study compares the reasons why targe and Small companies are adopting electronic commerce(e-commerce) based on an assumption of difference between two groups of companies. We collected data for contemporaneous analysis by classification with two groups of companies in Korea and developed an integrated model from the empirical studies and made Question papers for inspection of created hypothesis. Hypothesis is composed with nine factors ; Customers, Suppliers, Pertner Firms, Competitors, Relative Advantage, Cost Compatibility, CEO's Innovativeness and CEO's Involvement. The research shows Large company is influenced significantly by Customers, Relative Advantage, Cost, CEO's Innovativeness and Small company is by Competitors, CEO's Involvement.

Amyloid oligomers are believed to play important causal roles in many types of amyloid-related degenerative diseases. Many different laboratories have reported amyloid oligomers that differ in size, morphology, toxicity, and method of preparation or purification, raising the question of the structural relationships among these oligomer preparations. The structural plasticity that has been reported to occur in amyloid formed from the same protein sequence indicates that it is quite possible that different oligomer preparations may represent distinct structural variants. In view of the difficulty in determining the precise structure of amyloids, conformation- and epitope-specific antibodies may provide a facile means of classifying amyloid oligomer structures. Conformation-dependent antibodies that recognize generic epitopes that are specifically associated with distinct aggregation states of many different amyloid-forming sequences indicate that there are at least two fundamentally distinct types of amyloid oligomers: fibrillar and prefibrillar oligomers. Classification of amyloid oligomers according to their underlying structures may be a more useful and rational approach than relying on differences in size and morphology.

Surface subsidence is one of the problems caused by mined out caverns. Depending on the geologic conditions and mining methods, subsidence can occur in various forms. This report describes the ground stability assessment for the mining induced subsidence area where unfilled caverns still exist abandoned. Geologic features which could affect the stability of the ground were investigated and all the possible geophysical methods were employed to obtain data that could explain the state of the ground in question. Basic rock tests were conducted from the drill cores and rock mass classification was performed by core logging and borehole camera investigation. Numerical analyses were carried out to predict the ground stability using data obtained by various investigations. The result could have been more reliable if in-situ stress were measure and reflected in the numerical analysis.
