The direction of recent education literature points to the importance of creativity and creative practices, which also plays an important role in character education and has been recognized as being invaluable for the educational goals of the 21st century. As such, the goal of mathematics educators and researchers has also been on emphasizing the importance of building character and promoting creative practices. In this research, we study the pedagogical measures that can be easily implemented in classrooms to foster creative mathematical thinking and practices in students. In particular, the mathematical topic of interest is three-dimensional geometry, and especially polygons, and processes in which mathematical knowledge and creative practices play out in classrooms. For example, we explore how these creative lessons can be organized as the target internalization lessons, concepts definition lessons, regularity and relationship lessons, question posing lessons, and narrative story lessons. All of these lessons share three commonalities: 1) they require specific planning and execution challenges in order to achieve creative tasks, 2) they take advantage of open-ended problems, and 3) they are activity-oriented. Through this study, we hope to further our understanding on successful creative mathematical educational practices in the field of mathematics education, and help establish model lessons and materials for teachers and educators to use towards such goals.

The Long-Term Development Plan of the Pusan National University(PNU) has announced on 1991 in order to reach its roles and levels as an University with international standards, a Graduate School research-oriented and a core university in its community through accomplishment of this Plan. University libraries would be planned to support their universities' goals. Therefore the Library of PNU is facing on the task for supporting the Plan. The Collection for Korean Classical Materials (CKCM) is not limited in Korean Literature, Korean History, Korean Philosophy fields but covered the academic fields except a hightech science : Humanities, social science. pure science, applied science and arts etc. However, the Library of PNU does not have the organization, special librarian and budget for CKCM. Under this notion organization, budget and librarian for the collection would be followed. The CKCM contains the original editions, photography editions, copied issues. microform reproductions with comprehensive subjects in the fields of studies. Especially for the collection of treasure books the role of the Library of PNU induce to open individuals' collections or families' collections to public through the Library. The equipments for preserving rare books and treasure books are the conditioners for humidity and temperature, automatic extinguishment system. The reference materials, copy machine and reading room are requested for the user service of CKCM. The materials would be one of the most important thing in study and research. Therefore the Library of PNU need to pay attention to develop and preserve CKCM.

For microwave device applications, c-axis oriented high temperature superconducting YBa$_2$Cu$_3$O$_{7-{\delta}}$ (HTS-YBCO) epitaxial thin films on the r-cut sapphire substrate(Al$_2$O$_3$) were prepared. In order to reduce the lattice mismatch with a substrate and to enhance the crystallity of HTS thin films, CeO$_2$ buffer layer on the r-cut sapphire substrate was grown by the RF-magnetron sputtering. The YBCO films on the CeO$_2$ buffer layer were deposited using the pulsed-laser deposition (PLD) method. These HTS YBCO /CeO$_2$/Al$_2$O$_3$ multilayer thin films(30 $\times$ 30 mm$^2$) routinely exhibited a critical temperature(T$_{c}$) of 89 K from the R-T measurement. Using HTS YBCO/CeO$_2$ /Al$_2$O$_3$ multilayer thin film. We fabricated and characterized the microwave passive devices (planar type filters) with cryopack-age such as the coupled -line type low-pass filter (LPF) and the open-loop meander type bandpass filter (BPF).filter (BPF).).

Trade between Korea and China was 372million dollars accounting for 1.56% of total in 1988 and has been increased to 23,689 million dollars occupying 7% in 1997, which implies 32.2% increase on average per year. This trend will continue dramatically and consistently as China's open policy toward the world accelerates and korean companies advance into chinese market. The main trade routes are with marine transportation between korean west sea area and chinese San-Dong peninsula around east sea. However, due to the increasing traffic congestion on main roads connecting harbors and main consumer cities and capacity problem in west sea harbor areas, the logistics cost have been increased resulting in losing competitiveness of freight trade. Therefore, these road-oriented inland transportation means need to be changed to rail transport system to reduce congestion and to conserve natural environment. To achieve this scheme, efficient intermodal transportation system connecting road and rail should be constructed. These combined system will ensure timely delivery of goods and consequently the customers would make proper transportation schedule for the import/export goods in advance. Especially, combined transportation of Railroad and train ferry would cope with the logistics problem and this system would be efficient means for trade with not only China but further with many adjacent countries in central asia such as Kazakhstan and Uzbekistan

Purpose - This pilot study explores the gap between venture capitalists and young business graduates in Pakistan. Though the young graduates remain enthusiastic about choosing entrepreneurship as a profession, their success is subject to financial constraints. Research design, data, methodology - We administered a Likert-scale based questionnaire to 200 business graduates from June to July 2012, and interviewed ten venture capitalists from Islamabad and Lahore-two highly business oriented cities of Pakistan-to collect the data. The survey participation was on a voluntary basis without any financial sponsorship. Findings- There is a communication gap between the two parties (venture capitalists and business graduates), and a lack of trust in the entrepreneurial education and training offered in the educational institutions in Pakistan. The study, however, reveals the leading role of the Government in reducing this gap through certain measures. Conclusions - Some measures that can reduce the gap between venture capitalists and young graduates are: association of business schools with industry; financial institutions'initiatives to financially support the small and medium level projects of the economics and business students during their studies; establishment of placement bureaus in the business schools; and organization of regular open houses in the universities.

This thesis is a historical research about the Foreign Settlement at Mokpo as the fourth among the Open Ports which express the historical characters of Korean Modern, as a city which did not exist before the Korean Modern. So I analyzed positively the process of establishment and the process of urban form during the period which contained the characters of Concession, from 1897 to 1910. Even though the urban basic form of the Foreign Settlement at Mokpo was planned by Korean Goverment, it's townscape was changed to Japanese style by Japanese since Mokpo port was opened. Because it had settled by Japanese residents which had majority. But I found that the urban form was not composed by the Modern urban planning theory or method, but by the existing conditions such as topography and roads. The center in the settlement had shifted from the front region of Japan Consulate to the East region which was in the vicinty of Korean village. And also former internal oriented urban form had changed to the relevant composition with Korean village. All the changes in the Foreign Settlement at Mokpo was made by the Japanese which had majority, and it is a good example which expresses Korean Modern history.

The purpose of this study is to analyze and assess the family policy of the Lee administration and to suggest agendas for sustainable future family policy. Traditionally, families are a unique unit of production and reproduction of family members and social laborers. In addition, families are the social safety net help people survive in a society. Therefore, family policies play an important role in contemporary society. In this context, we review the literature related to family and social policy, and the contents of Ministry for Health, Welfare and Family Affairs, which is the main authority in Korea. The results are as follow: Firstly, the Lee administration ignored the data showing that family policy should be a unique policy, and not a sub-division of welfare policy. Secondly, there is no difference between the active welfare policy of the Lee administration and policies of past administrations. Finally, this study suggests that subjects of future oriented family policy should focus on co-developing programs for the individual, family, and society, to develop problem-prevention and family needs- ordered policy, and to make integrated family policy through laws and delivery systems such as Healthy Family Centers.
