Identity is the concept which approaches individuals' affective problems with the social and cultural view. The previous studies on the problems, studied the attitudes, beliefs, or emotions while they restricted the problems to teachers or students' private problems. Otherwise, identities focus on individuals which participate to any community and share its social practices(Mclead, 1994). This study purposed to get an understanding on the teaching and learning mathematics in elementary mathematics classroom with an ethnographic view, while we consider mathematics as a kind of social practices, and mathematics classrooms as communities of practice. We analysed teacher's identities on mathematics and teaching mathematics depending on her responses of the questions as following: How does she think about mathematics, what are the instructional goals in her mathematics classroom, how do students learn mathematics in her mathematics classroom. In addition, we analysed students' identities on mathematics and learning mathematics depending on their responses of the questions as following: What do students think of mathematics, do they like mathematics, why do they study mathematics, how do they feel their mathematics classroom(describe your classroom) and themselves in it(describe yourselves in your classroom), what are their duties and what do they do actually in their mathematics classroom.

The UCP is an authoritative compilation of the customs and practice of letters of credit observed by most of the participants in the transaction. It remains the most successful set of private rules for trade ever developed. First issued in 1933, the UCP has been through five revisions, the latest being the present UCP 500, which came into force in 1994. Since 1994, new developments in transport, insurance, electronic commerce and banking industry have spurred the current revision of the rules. The ICC Banking Commission approved UCP 600 on October 25, 2006 by a unanimous vote of 91 to 0. The revision, which will come into effect on July 1, 2007, incorporates a number of changes from UCP 500 as follows : UCP 600 has a leaner set of rules, with 39 articles rather than 49 articles of UCP 500; New sections on "definitions" and "interpretations" have been added to clarify the meaning of ambiguous terms; The phrase "reasonable time" for acceptance or refusal of documents has been replaced by a firm period of five banking days; UCP 600 allows for the discounting of deferred payment credits. However, UCP 600 has two main problems such as the inconsistency with insurance industry and the banking community-oriented rules. We have some months before the commencement of UCP 600. From today to the commencement of UCP 600, we should study the full contents of UCP 600 and the influences on the trade industry.

Purpose - The purpose of this paper is to investigate the determinants of corporate anti-corruption practice disclosure (ACPD) from the perspective of rent-seeking theory. Research design, data, and methodology - Data are hand-collected from corporate social responsibility reports (CSRR) issued by 724 A-share listed firms in China. This paper provides an empirical analysis of the relationship between ownership structure and corporate ACPD as well as its moderating role in the institutional environment. Results - Our findings indicate that rent-seeking is a key factor in influencing corporate ACPD. State-owned enterprises disclose significantly more anti-corruption information than private ones in order to achieve personal promotion of top executives. Monopoly enterprises reported significantly less anti-corruption information than enterprises in competitive industries due to their rent-seeking behavior. The reduction of government intervention and improvement of legal environment are helpful to curb corporate rent-seeking activities and enhance the level of corporate ACPD. Conclusions - Rent-seeking is an important factor in explaining corporate voluntary disclosure in emerging countries. Institutional environment also plays a moderating role in the relationship between ownership structure and corporate voluntary disclosure. Our results are of interest to policy makers, regulators and market participants that are interested in corporate voluntary disclosure and corruption prevention.

Many closed schools of about more 3,000(2006 year) have occurred all over the country according to governmental policy of 1982. These closed schools were sold or rent to institution, local government, and a private, and are used by various usage such as novitiate, institution, educational facility, art creation facilities, warehouse, and factory. But, unimproved closed school facilities are still reaching for about 450. Among practical use example of such closed school, alternative educational facility, practice facilities, art creation facilities etc. with closed schools which have general surrounding natural landscape and environment uses well preserved were applied consciousness and the practice about environmental problem to ecological concept. Also, a lot of discussions about ecological concept and study for desirable solutions about practical use of closed schools example have been achieved. However, it is hard to find various ecological practical use examples at filed. In such background, this research wishes to investigate changing space and facilities variously and its usage which is applied ecological concept with regional closed schools.

The purpose of this study is to diagnose the problems of mathematics education in Korea by conducting an in-depth analysis of international comparative studies, a Delphi method, and a survey. Further analysis of TIMSS and PISA results also reveals several negative aspects of mathematics education practice in Korea. The mathematics education experts' opinions collected by Delphi method were classified into 12 categories: private education and test-driven education, curriculum and textbooks, lessons, evaluation, teacher, learner, teaching aid and facilities. affective aspects of mathematics, discrepancy between a theory and a practice, preservice/inservice teacher education and teacher employment test, education policy, and overall. Another survey was conducted to focus more on the development of curriculum which is a pending issue. Considering the fact that mathematics education should contribute to improve practical aspect as well as elaborate theoretical aspect, this study lays a foundation of improvement of mathematics education in Korea.

PURPOSE. This retrospective study aims at the evaluation of implant-supported overdentures (IODs) supported by ceramo-galvanic double crowns (CGDCs: zirconia primary crowns + galvano-formed secondary crown). MATERIALS AND METHODS. In a private practice, 14 patients were restored with 18 IODs (mandible: 11, maxilla: 7) retained by CGDCs on 4 - 8 implants and annually evaluated for technical and/or biological failures/complications. RESULTS. One of the 86 inserted implants failed during the healing period (cumulative survival rate (CSR) implants: 98.8%). During the prosthetic functional period (mean: $5.9{\pm}2.2years$), 1 implant demonstrated an abutment fracture (CSR-abutments: 98.2%), and one case of peri-implantitis was detected. All IODs remained in function (CSR-denture: 100%). A total of 15 technical complications required interventions to maintain function (technical complication rate: 0.178 treatments/patients/year). CONCLUSION. Considering the small sample size, the use of CGDCs for the attachment of IODs is possible without an increased risk of technical complications. However, for a final evaluation, results from a larger cohort are required.

This study is for the understanding of the role of fortunetelling and the "Scripture of Fortunetelling(占察經)" through the relationship between the manners and customs of Koreans and the Buddhist Scripture dealing with the fortunetelling. It is meaningful to understand how it is related with Buddhism. As a result, I perceived that Koreans have lived with fortunetelling and that the role of fortunetelling in from private person to the country. I saw there were four big roles; to clean the uncertainty of the future to fulfill the expectations, to confirm the justice of what he or she did, to cure, and to choice. Looking into "Memorabilia of the Three Kingdoms(三國遺事)", I see that the Scripture of Fortunetelling and the ceremony of fortunetelling was popular and those great monks such as Wongwang, Wonhyo, Jinpyo and Jihye presided these ceremonies. The structure of the "Scripture of Fortunetelling(占察經)" has the hierarchy of Fortunetelling, Penance, Practice, Awakening, and Salvation of the world. So fortunetelling motivated every stage of practice. The role of fortunetelling in "Scripture of Fortunetelling(占察經)" is to intermediate. For this purpose it divided the attitude for the fortunetelling into two categories; for the urgent real life and just for enjoying. But they seriously dealt with both results. They used the fortunetelling in order to accomplish the ultimate purpose of Buddhism. So the fortunetelling is a mean of propagation of Buddhism and a intermediary of awakening and salvation.

Objective: The purpose of this study was to assess the long-term stability of rapid palatal expansion (RPE) followed by full fixed edgewise appliances. Methods: This study included 67 patients treated using Haas-type RPE and non-extraction edgewise appliance therapy at a single orthodontic practice. Serial dental casts were obtained at three different time points: pretreatment ($T_1$), after expansion and fixed appliance therapy ($T_2$), and at long-term recall ($T_3$). The mean duration of the $T_1-T_2$ and $T_2-T_3$ periods was $4.8{\pm}3.5years$ and $11.0{\pm}5.4years$, respectively. The dental casts were digitized, and the computed measurements were compared with untreated reference data. Results: The majority of treatment-related increases in the maxillary and mandibular arch measurements were statistically significant (p < 0.05) and greater than expected for the untreated controls. Although many measurements decreased postretention ($T_2-T_3$), the net gains persisted for all of the measurements evaluated. Conclusions: The use of RPE therapy followed by full fixed edgewise appliances is an effective method for increasing maxillary and mandibular arch width dimensions in growing patients.
