The Museum of Chosen General Government(MCGG) was a supreme organ to take charge of business affairs of historical remains Japanese imperial rule. The MCGG was established in Kyongbok Palace in 1915. The MCGG was changed the reorganization of the Chosen General Government(CGG) setups, the MCGG was to maintain the cultural assets, to excavate the ruins and to put on display the remains. However, the Japanese colonist took advantage of the MCGG for political purposes. They didn't use the MCGG to promote the research of Korea culture. Therefore, the MCGG was an organization to belong to the Department of Education of the CGG. In this reason, the MCGG produced the amount of public document to business affairs. Now, This document left in the Museum of Korea. We have seen the document to study the cultural policies and the cultural assets of the CGG. This document includes the abundant information for the historical remains and ruins at that time. Accordingly, this document will help to survey the archaeological research and historical research. In addition, this document will help to manage the cultural assets. What then is the advantage of this document? The first is to see the cultural policies of the CGG through this document. The Japanese colonist took advantage of Korea history, which was low-grade culture, to justify rule of the colony. Therefore, they needed collect Korean assets to verity their theory. The second is to see the administration system of the MCGG. Indeed, this document includes information of organization of the MCGG, the policies and the process of the MCGG. In substance, we can see the systemic proceedings of the MCGG. The third is to provide historical materials to the historian. This document has the persons to plan the colonial culture policy of the MCGG, and events to rule the Korea culture. Moreover, the document of the MCGG would help to inquire into the truthfulness of history and to get the national identity.

Teachers should be able to reorganize the curriculum according to the student level, reorganize textbooks freely, and distribute them to students. However, current paper-textbooks are difficult to modify or edit some contents and distribute them to students, also current digital textbooks are grouped into units, so the order or educational resources cannot be reconstructed. In addition, The digital textbooks are difficult to update external links or the latest resources, and to contain various multimedia materials or high-definition realistic content due to capacity limitations. Therefore, this study presented functions: teaching and learning and evaluation functions, resources search and sharing functions, learning records and analysis functions, screen showing and printing functions, so that teachers can provide customized learning by level to students using digital textbooks. Through the expert Delphi survey, detailed functions for each area were divided into teachers and students. We proposed expanding and developing digital textbooks to various subjects, and distributing various teaching and learning models using digital textbooks.

This research treated the secondary school teachers as the research scale and the research targets included the following: secondary school (employ unit), center of teacher education, and qualified teachers. In terms of these three groups of people, the topics of exploration focused on the perception of suitable teachers, perception of evaluation standard during the process of teacher examination and the relationship among teacher examination systems. The research was managed by two phases: the first phase referred to literature reorganization, expert interview, the qualities and conditions of suitable teachers, important evaluation standard during the process of teacher examination and teacher examination system used; the second phase included questionnaire survey, employ school acquisition, the perception of centers of teacher education and qualified teachers toward the suitability condition and examination evaluation standard in the first phase and teacher examination system used. This research found out that as to the perception of suitable teachers, through data collection, there were six factors reorganized. The levels of their importance were as follows: education devotion, teaching capacity, class management, capacity to guide special students, capacity to communicate with the parents and the will to undertake administrative works. Noticeably, employee unit and centers of teacher education apparently valued class management more, compared with trained teachers; as to evaluation standard of examination, the analytical result found out that the perception of three groups were different in terms of the views toward educational works, written examination data, candidate's age, club experience at school and capacity to use multimedia support teaching materials. This research further proposed six suggestions for centers of teacher education and trained teachers: (l) employ schools considerably valued educational devotion; (2) trained teachers tended to neglect the importance of class management; (3) employee unit considerably cared about the new teachers' competence to use multimedia support teaching materials; however, trained teachers did not have the same view; (4) employee unit considerably cared about new teachers' views toward educational works as well as the candidates' ages; (5) generally speaking, trained teachers neglected the importance of club experience at school; (6) the data revealed that written examination data was not relatively important in terms of teacher examination.

The purpose of this study was to investigate the difficulties of science classes experienced by newly appointed elementary school teachers in terms of science content knowledge and teaching method, and to suggest some implications for their effective adaptation. We recorded science lessons conducted by 3 beginning elementary school teachers with less than 5 years experience and also analyzed their classes and interview materials. The results were as follows. First, difficulties that they experienced in science content knowledge was the possession of scientific errors or misconceptions, the lack of awareness and confidence in scientific concepts and principles, and the possession of negative concept about learning materials. Second, difficulties that they experienced in teaching method was the absence of reorganization of the textbook contents, using closed questions, one-sided instructions and explanations by teacher, the application of incomplete analogy, and the lack of understanding about experiment activities. The implication from this study is that beginning teachers need to be provided with curriculum oriented in experiment at teachers college and to participate in various types of educational opportunities.

The Purpose of this study was to evaluate the effect of occlusion on the mechanical strength of periodontal fibers during retention periods after experimental tooth movement. In the Sprague-Dawley male rats weighing 200g or more, the ntraoral elastics were inserted into the both right and left interproximal space between upper first and second molars for tooth movement. kiter 4 days later, the left lower first, second, and third molars were extracted for differentiating the non-occlusal side from the occlusal side in the same mouth. At the same time the elastics were removed and then light cured resin was Placed in the space between upper first and second molars following undercut was made for retention bilaterally. From the beginning of retention, 7 rats were sacrificed at 0, 4, 8, 12, 16, 20 days respectively. For evaluating of magnitude on the mechanical strength of periodontal tissue, the maximal shear load of the upper first molars were measured bilateraly during extraction using Instron Universal Testing Machine. The results of this study were obtained as follows : 1. In the occlusal side, the maximal shear load was increased from no retention to retention 20 days group as time was going and statistically difference was shown from retention 12 days group (p<0.05). 2. In the non-occlusal side, the maximal shear load was increased slightly from no retention to 20 days group as time was going but there was no statistically difference (p>0.05). 3. The result compared with the maximal shear load between occlusal and nonocclusal side showed no statistically difference until retention 8 day group (p>0.05), but showed statistically difference from retention 12 day to 20day group (P<0.05). These results show that occlusion had an effect on mechanical strength of the periodontal fibers during retention periods after experimental tooth movement; therefore, it is suggested that occlusion should be considered while the retainer types and retention period are planned.

This study investigated the common features of the best practices in the science classroom, which is the core of school education. The underlying assumption of this research is that the fulfillment of school education is possible with substantial instruction of school curricular areas. The substantial learning of any curricular area depends on each classroom lesson. Data from classroom observations in-depth interviews with teachers and a group of students, a collection of instructional materials were used to extract common characteristics of best practices implemented by 10 exemplary secondary-school science teachers. Common features of best science practices were analyzed in terms of (1)reorganization of science content, (2)pedagogical skills, (3)evaluation, and (4)teachers' efforts for professional development. Results indicated that exemplary science teachers adapted curriculum and textbook content according to students' level and learning context, were able to use a variety of instructional methods and strategies, provided cooperative and intellectually challenging learning environment, and improved their instruction based on assessment results. Also, these exemplary teachers not only improved their own classroom practices, but also participated actively in various professional community of science teachers to share their practical knowledge with their colleagues. They took an active role in teachers' in-service education.

This study aimed to suggest a resolution through a research on actual condition of appreciation class among art classes in elementary school. For this object, this study is about the need and problem of appreciation through concert of art appreciation and educational meaning. And this study is research, based on 200 current teachers to teach the art education of appreciation in Seoul. In the case of student research, this study show the current appreciation education focusing on 200 students in Seoul. The teachers has been seeing the importance of the appreciation education, but that education has been performing in the poor environment without aids and appreciation materials. And they thought that the most effective way to teach the appreciation of art is the on-site education such as the invitation of art-gallery or museum. The Change of realization about art, together with improvement of realistic situation, is important. But more important problem is the role and the realization of teacher who teach art directly. If the teacher's viewpoint to teach directly education of appreciation is examined, there are following problems First, it lacks realization about the importance of appreciation education. Teachers who teach a student have been taken functional art education mainly and this trend has been spread in the whole of society, therefore, the importance about the teaching of appreciation is negligent and is handled indifferently. Also, Teachers do not offer opportunity to obtain professional information of art appreciation map to overemphasize the study of practical teaching research. Second, elementary schools teacher is, for the most part, occasion that homeroom teacher teaches all object classes, and complete charge teacher is selected only some. Therefore, teacher in charge who play most a lot of subjects is difficult to recognize the importance of art teaching appreciation subject or class. There must have been a research about the educational preventive measures as suitable support, reorganization of at time and experts in superior office educational institution. Trough this study, I could know that front-line teacher should be specialized and more complete charge teacher should be needed urgently. Finally, the teachers must break the custom of the art appreciation and develop various art appreciation method. And the teachers have to lead the students to be interested art appreciation. That's what cultivate the students' aesthetic feeling and genius.

Purpose: Cortical reorganization has an important role in the recovery of stroke. We analyzed the compensatory cerebral and cerebellar perfusion change in patients with unilateral cerebral infarction using statistical parametric mapping (SPM). Materials and Methods: Fifty seven $^{99m}TC-Ethylene$ Cystein Diethylester (ECD) cerebral perfusion SPECT images of 57 patients (male/female=38/19, mean age=$56{\pm}17\;years$) with unilateral cerebral infarction were evaluated retrospectively. Patients were divided into subgroups according to the location (left, right) and the onset (acute, chronic) of infarction. Each subgroup was compared with normal controls (male/female=11/1, mean age=$36{\pm}10\;years$) in a voxel-by-voxel manner (two sample t-test, p<0.001) using SPM. Results: All 4 subgroups showed hyperperfusion in the ipsilateral cerebral cortex, but not in the contralateral cerebral cortex. Chronic left and right infarction groups revealed hyperperfusion in the ipsilateral primary sensorimotor cortex, meanwhile, acute subgroups did not. Contralateral cerebellar hyperperfusion was also demonstrated in the chronic left infarction group. Conclusion: Using $^{99m}Tc-ECD$ SPECT, we observed ipsilateral cerebral and contralateral cerebeller hyperperfusion in patients with cerebral infarction. However, whether these findings are related to the recovery of cerebral functions should be further evaluated.

Purpose : Skip the repetitive HRCT axial scan in order to reduce the exposure of patients during chest HRCT scan, Helical Scan Data into a reconstructed image, and exposure of the patient change and visually evaluate the usefulness of the HRCT images. Materials and method : Patients were enrolled in the survey are 50 people who underwent chest CT scans of patients who presented to the hospital from January 2015 to March 2015. 50 people surveyed 22 people men and 28 people women people showed an average distribution of 30 to 80 years age was 48 years. 50 patients to Somatom Sensation 64 ch (Siemens) model with 120 kVp tube voltage to a reference mAs tube current to mAs (Care dose, Siemens) as a whole, including the lungs and the chest CT scan was performed. Scan upon each patient CARE dose 4D (Automatic exposure control, Siemens Medical Solution Erlangen, Germany) was to maintain the proper radiation dose scan every cross-section through a device that automatically adjusts the tube current of. CT scan is the rotation time of the Tube slice collimation, slice width 0.6 mm, pitch factor was made under the terms of 1.4. CT scan obtained after the raw data (raw data) to the upper surface of the axial images and coronal images for each slice thickness 1 mm, 5 mm intervals in the high spatial frequency calculation method (hight spatial resolution algorithm, B60 sharp) was the use of the lung window center -500 HU, windows were reconstructed into images in the interval -1000 HU to see. Result : 1. Measure the total value of DLP 50 patients who proceed to chest CT group A (Helical Scan after scan performed with HRCT) and group B (Helical Scan after the HR image reconstruction to the original data) compared with the group divided, analysis As a result of the age, but show little difference for each age group it had a decreased average dose of about 9%. 2. A Radiation read the results of the two Radiologist and a doctor upper lobe and middle lobe of the lung takes effect the visual evaluation is not a big difference between the two images both, depending on the age of the patient, especially if the blood vessels of the lower lobe (A: 3.4, B: 4.6) and bronchi(A: 3.8, B4.7) image shake caused by breathing in anxiety (blurring lead) to the original data (raw data) showed that the reconstructed image is been more useful in diagnostic terms. Conclusion : Scan was confirmed a continuous, rapid motion video to get Helical scan is much lower lobe lung reduction in visual blurring, Helical scan data to not repeat the examination by obtaining HRCT images reorganization reduced the exposure of the patient.
