The r-ary number sequences given by $$(b^{(r)}_n)_{n{\geq}0}=\Large{\frac{1}{(r-1)n+1}}(^{rn}_n)$$ are analogs of the sequence of the Catalan numbers ${\frac{1}{n+1}}(^{2n}_n)$. Their history goes back at least to Lambert [8] in 1758 and they are of considerable interest in sequential testing. Usually, the sequences are considered separately and the generalizations can go in several directions. Here we link the various r first by introducing a new combinatorial structure related to GR trees and then algebraically as well. This GR transition generalizes to give r-ary analogs of many sequences of combinatorial interest. It also lets us find infinite numbers of combinatorially defined sequences that lie between the Catalan numbers and the Ternary numbers, or more generally, between $b^{(r)}_n$ and $b^{(r+1)}_n$.

This study focus on interest for arrears and filling of the gaps left in Article 78 of CISG. In the case of CISG, Article 78 provides for interest any time a payment under a contract is untimely, but does not specify a particular rate of interest or a method to determine such a rate. This issue did not cause any uncertainty under ULIS, the CISG's antecedent, since Article 83 of ULIS provided for 1%p above the official discount rate in the creditor's country. Lacking any CISG general principle as well as any indication by the very same CISG, one can only conclude that the matter must be deferred to the domestic rule of private international law. Actually, resorting to private international law is not only admissible, but expressly required by Article 7(2). In the interpretation and filling of the gaps left in Article 78, there is a considerable difference of opinion especially amongst commentators on whether the gap is a lacuna praeter legem, i.e., one being governed by, but not expressly settled in the CISG, or whether it is an issue falling outside the scope of application of the CISG, i.e. a lacuna intra legem. The protagonists of the former view lay emphasis on the overall objective of the CISG, namely to create a uniform law, whereas the supporters of the latter view refer to the legislative history of Article 78 as the dominant principle in interpreting Article 78. Some authors believe that the issue of determining the rate of interest is not dealt with by CISG and it is, therefore, governed by the applicable domestic law, which is the subsidiary law applicable to the sales contract, since "no special connecting points seem to have developed for the entitlement to interest." In the light of the relevant case law, it seems correct to conclude that the interest rate is not determined by CISG and that courts normally determine it according to their own rules of private international law. While CISG Article 78 expressly does not deal with this issue, PICC Article 7.4.9 and PECL Article 9.508, on the other hand, set forth a precise method for computing interest. Although a method like the one set by PICC may be useful and may encourage uniformity, it still cannot be used under the CISG. The PICC or PECL formula may, however, be a very good starting point in a de jure condendum analysis when a new Article 78 will be drafted, if an interest rate method will ever be embodied in the text of an international convention.

Objectives : The new health technology assessment system was introduced in April 2007. The purpose of new health technology assessment is assessing safety and efficacy in deciding a behavior of new health technology according to the Health Insurance Act. This study aims to understand the present status of new health technologies of Korean medicine. Methods : This research introduces new health technologies and their present status, and searches for a development direction for the new health technology of Korean medicine in the future. Results : Thirty seven cases(3%) of Korean medicine doctors who utilized new health technologies application were found. In the status about new health technologies application by technologies assortment, diagnostic test techniques were used more often than treatment skills. New medical technology that included korean medicine doctor as actual user was only one item, i.e. HCV antibody test. Conclusions : In order for the new health technology of korean medicine to settle down well, continuous interest and efforts of both government and medical community are necessary.

There has been increasing interest in recent years in the pedagogical importance of counter-examples that focuses on pedagogical perspectives. But there is no research that undergraduate students' generating counter-examples and proposing the true statements. This study analyze 6 undergraduate students' response to interview tasks and the process of their generating counter-examples and proposing true statements. The results of interviews are that the more undergraduate students generate various counter-examples, the more valid they propose true statements. If undergraduate students have invalid understanding of logical implication and generate only one counter-example, they would not propose true statements that modify the given statement, preserving the antecedent. In pre-service teacher's education and school mathematics class, we need to develop materials and textbooks about counter-examples and false statements.

Renaissance Age is called the Period of Discovery because of great development of the economy and the science, and is known the Period of scientific analysis of Man and of interest of Nature out of a blind obedience in the Middle ages. Especially in visual art architecture, painting and sculpture, the rational spirit of Renaissance actually and distinctly communicates the meaning of Work through the scientific and mathematical expression after a finding Perspective by Brunelleschi. So the puropse of this study is to clarify the substancial meaning of Renaissance Art by investigating the expression applied Perspective to the works of Brunelleschi's architecture, Donatello's sculpture and Masaccio's painting.

Objectives : Nowadays, the assessment of new health technologies is gaining interest as an important issue for the safety of national health in the rapidly changing medical environment. The aim of this study is to understand how ignorant the korean medicine doctors are of new health technologies. Methods : The authors conducted a survey on the status of the ignorance of new health technologies in Korean medical doctors by e-mail. Results : Korean medical doctors' ignorance of new health technologies proved serious. The awareness of the law, however, was reached to some degree. The respondents answered that the present items of Korean Medicine listed in the medical care expenses by national health insurance system are too deficient to treat their patients effectively. Conclusions : It is strongly needed to try for more active registration of Korean medical new health technologies.

We propose a semi-automatic and dynamic indexing algorithm for multi-media database(e.g. movie files, audio files), which are difficult to create indexes expressing their emotional or abstract contents, according to user's sensitivity by using user's histories of access to database. In this algorithm, we simply categorize data at first, create a vector space of each user's interest(user model) from the history of which categories the data belong to, and create vector space of each data(title model) from the history of which users the data had been accessed from. By continuing the above method, we could create suitable indexes, which show emotional content of each data. In this paper, we define the recurrence formulas based on the proposed algorithm. We also show the effectiveness of the algorithm by simulation result.

Feature-based modeling and history-based modeling are the two main paradigms that are used in most of current CAD systems. Although these modeling paradigms make it easier for designers to create solid model, it may pose dependency constraints on features that are interacting one with another. When editing such features, these constraints often cause unpredictable and unacceptable results. For example, when a parent feature is deleted, the child features of the parent feature are also deleted. This entails re-generations of the deleted features, which requires additional modeling time. In order to complement this situation, we propose a method to delete only the features of interest by disconnecting the dependency constraints. This method can provide designers with more efficient way of model modification.

The purpose of this paper is to find out the identity and succession of traditional Hanok villages by analyzing the location, layout, and spatial organization of neo-Hanok Village, which was built in Korea. So far, neo-Hanok Village has not prepared a specific institutional mechanism despite the government's support and growing public interest. In addition, the purpose of neo-Hanok Village has not been verified, even though it was built all over the country for the purpose of the dignity and succession of the traditional Hanok Village. This study examines how the spatial organization elements of the traditional Hanok Village are planned according to the design principles of the old literature and applies them to the neo-Hanok Village to determine the succession of the traditional Hanok Village.

Objectives : As the number of patient with dementia increases, interest in mild cognitive impairment (MCI), which is a pre-dementia stage, has been expanding. In this study, we investigated the effects from selected clinical research articles to evaluate the effectiveness of non-pharmacological interventions. Methods : We searched MCI related articles on MEDLINE and the Web of Science using keywords related to MCI. We selected 26 articles, and 13 evaluated efficiency using the Jadad score. Results : Physical exercise and cognitive remediation techniques were effective for improving MCI. Transcutaneous electrical nerve stimulation, taichi, and music belonged to "perhaps" effectiveness group. Many of the 13 articles that evaluated MCI using the Jadad score evaluated them as "good" or "poor", and only three articles evaluated MCI as "excellent". Conclusions : The present evidence suggests that cognitive remediation techniques to improve memory and physical exercise were effective for people with MCI. However, further studies are needed to identify the physical exercise effects.
