  • The majority of construction projects, from the initiation phase to the project completion and operation phase, are influenced by various types of corruption. Iran, as a developing country, has been suffering from this issue in bidding, tendering procedure, contracts etc. Therefore, due to the importance of this issue, this study attempted to identify the causes of corruption and evaluate the most significant factors in the construction projects in Iran. To this aim, an intensive literature review was performed to investigate the various types of corruption and identify the potential factors causing corruption in construction projects. The questionnaire survey was designed, considering twelve forms of corruption, including 77 causes of corruption in construction projects in Iran. Out of 220 distributed questionnaires, 188 were returned by the participants. The valid collected data sets were analyzed and then Exploratory Factor Analysis was applied. It was discovered that "Inappropriate power-sharing," "Lack of obligation for human resources to properly use resources and abide by the rules and regulations" and "Lack of any monitoring of the government's performance" are the most significant factors. Findings from the study would be valuable for the construction projects authorities and academia in order to combat corruption in the construction projects.

  • This paper deals with the research trend of world geography (excluding geography of Korea) in Korean geographers' academic society through the analysis of the articles published during the last 21 years in three Korean geographical journals(Journal of the Korean Geographical Society, Journal of Korean Association of Regional Geographers, and Journal of Cultural and Historical Geography). The portion of articles concerned with world geography is relatively the lowest during the years 1990-1994, relatively the highest during the years 1995-1999, and rather decreasing during the years 2000-2010. The research areas of the articles concerned with world geography are mostly limited to USA, Japan, China, and Europe. It is not only expected that the more research on world geography should be done by Korean geographers but also that the research areas should be expanded in worldwide areas at this time when Korea is entering an international, global, and multi-cultural society.

  • This paper compares two recent methods for exploring a scientist's research history: citation identity and self-citation network. The former is proposed by White(2000), while the latter is suggested by Hellsten et al.(2007). An experimental citation analysis was carried out on the research output of Young Mee Chung, a renouned Korean information scientist. The result shows that the two methods divided the research period into two sub-periods in the same way. They also identified the major research themes very similarly. In the analysis of each method's performance in depth, the two methods revealed different functions to understand a researcher's history. Citation identity was useful to identify authors who have affected Chung's research in terms of research topics. whereas, self-citation network was successful to identify the core papers and leading papers of the research sub-periods. This study indicates the combination of two methods can provide rich information on a scientist's research history.

  • Korea has begun institutional education for the gifted since 2002. It has quantitatively expanded, but needs rather qualitative growth. The purpose of this study is investigating a case of scientific education for the gifted in Russia. Three principal of Russian science academy, one educational psychologist, and one education-government official had in-depth interviews for this study. All data from interviews were carefully analyzed. The Science education for the gifted in Russia gives us full assurance that students should reveal their potential ability with the specialized program in school. The Russian run various, particular academies because they try to search for potential ability in manifold areas. The people in charge of scientific education in Korea should make an effort to seek for varied routes in the way of searching for hidden originality and potential ability.

  • This paper provides a review of the historical development story of the NCTM 1989 Standards based on perspective of history of U. S. mathematics education and research in the 1970s and 1980s. In contrast to other nations, the U. S. has always favored local over national control of education. But by 1983, mounting evidence of failures of U. S. education moved the authors of A Nation at Risk to recommend strengthened requirements, rigorous Standards, and higher expectations for all students. In response to A Nation at Risk, the NCTM began to develop the nation's first educational Standards. This paper satisfies the readers who desire to know the entire development story of the first Standards.

  • This study is to understand intuition that is the tool of invention and the one factor of the creative thinking in mathematical education. For this, I examine the nature of intuition and the history of research about intuition. And I study the result of research about intuition in cognitive psychological perspectives. This study brings to a focus in informational processing model. Informational processing model is similar to the mathematical problem solving process that is expressed linear process. Recently, parallel distributed processing models try to understand the nature of intuition. But any models cannot adequately explain the nature and the phenomena of illumination of intuition. Some scholars try to examine the intuition in mathematical education. But systematic and practical research is rare. So, I suggest the mathematical educational implications about intuition. Conclusively, it is necessary to systematic concern in intuition and the methods of improvement of intuition in mathematical education.

  • It is the aim of this paper to suggest the method constructing abstract schema in similar mathematical problem solving processes. We analyzed closely the existing studies about the similar problem solving. We suggested the process designing a method for helping students construct an abstract schema. We designed the teaching method constructing abstract schema by appling this process to a group of similar problems chosen by researchers. We applied the designed method to a student. And we could check the possibility and practice of designed teaching method by observing the student's reaction closely.

  • The outbreak of the First and the Second World Wars cast great shadow across the Europe including mathematical society. The IMU led by French mathematicians after the First World War ceased to exist because it was used politically. As Europe ran into the Second World War, all the international mathematical activities were ceased. Prominent mathematicians were put into camp by Nazi or moved to the United States of America. After the war, European mathematicians did not have capacity to represent the international mathematical society anymore. This led Stone and other American mathematicians to form the new IMU, which was independent of political ideology. This paper studies the birth process of the new IMU after the War and some major events that happened to ICM in 1950s.

  • Througout the literature, various opinions and recommendations are presented concerning educational backgrounds for subject specialist librarianship. However, the Korean library and information science education is designed as the college program, and n, utilization of either minor or double major programs is regarded as the best to produce qualified subject specialist librarians. Nevertheless, the courses in the library and information science should be promoted first. Accordingly, this study starts with the assumption that the subject bibliography course in the library and information science is designed directly or indirectly to educate students as subject specialist librarians. For this, law and law firm library were explored as examples, and then, finally a law bibliography was provided for the training of the law specialist librarians.
