The center of resistance is a important determining factor of tooth movement pattern. Laser speckle interferometry, recently developed for noninvasive measurement of small displacements (microns), was used to detect the center of resistance of a maxillary canine which has normal tooth axis and distal curved root in dry human skull. Laser holographic interferometry was used to verify the results of laser speckle interferometry The following result were obtained; 1. In measurement of the degree of rotation, center of resistance was localized when the traction line passed 4.4/18.0 level from alveola crest to root apex. 2. In measurement of the degree of tipping, center of resistance was localized when the traction line passed 4.6/18.0 level from alveola crest to root apex. 3. In holographic determination, the center of resistance was observed when the traction line passed between 3mm to 6mm level from alveola crest to root apex, therefore the results using laser speckle interferometry was coincided with holographic results.

The purpose of this study is to examine how newly-appointed elementary school teacher majoring in the advanced-level course of social studies education can understand their own studying experiences and organize the meaning as the dynamic and subjective individual learners, at the standpoint of transformative learning theory. Through it, this study intends to show reference frame`s contents and changing aspect in teachers` experiences, to interpretate the characteristics of studying experience in relation with the growth of teachers` professionalism and examine what the factors related with teachers` studying are. For the studying process of newly-appointed elementary school teacher, firstly, it was interpreted by additional study and transformative learning but transformative learning showed what things achieved at the standard reexamining basically premise and purpose in teachers` class practical behavior, different from the knowledge which can be known more, and transformative aspect of standpoint through the rational discourse with colleague teachers. Secondly, in the process of transformative learning, there were critical reflection, rational discourse and practical behavior dynamically. Thirdly, the content of reference frame for teachers` instrumental studying area was mainly related with contents which have appropriateness of teaching society for newly-appointed teachers` adaption, and teaching/studying. So establishment and practice of systematic educational plan were the method for student guidance by main contents and teacher`s belief. On the contrary, the content of reference frame for communication area and emancipatory area has mostly the content including teacher`s self-critical reflection for the content of reference frame, for the previous instrumental studying area.

북한의 금융실태와 개혁방향 및 남북 협력과제

본 연구는 북한 금융의 현황과 변화 등 북한의 금융실태를 살펴보고 주민들의 금융이용실태를 조사 분석했다. 북한 주민을 대상으로 직접 적인 조사가 불가능하여 탈북민을 대상으로, 북한에 거주했을 때의 금융이용 현황을 조사 한 것이다. 분석 결과 북한의 은행 등 금융은 매우 낙후돼 있으며, 주민들은 은행을 거의 이용하고 있지 않았으며 사금융을 이용하고 있는 것으로 나타났다. 북한 경제가 발전하기 위해서는 금융이 매우 중요하다. 금융 기능을 할 수 있는 은행시스템이 구축되고 지속적으로 금융 개혁이 이루어져야 할 것으로 보인다. 한반도 평화와 번영의 시대에 남북한 금융협력을 적극 추진할 필요가 있다. This study looked at the current state of North Korean finance and examined the financial use of the residents. This is a survey on financial use of North Koreans living in North Korea, which made it impossible for them to conduct a direct survey of North Koreans. According to the analysis, North Korea s financial institutions, including banks, are very backward. Residents were found to have little use of the bank and were using private banking. Finance is very important for the North Korean economy to develop. A banking system that can function as a financial institution will have to be established and a gold price reform will continue. We need to actively promote inter-Korean financial cooperation in an era of peace and prosperity on the Korean Peninsula.

Nowadays there are lots of changes in the domestic railroad industries because of the reorganization in the industries, operation of KTX and expansion of city train in local areas. To cope with these changes effectively, domestic & abroad safety guideline and regulation were investigated and reviewed by railroad safety technical development project. Based on this project, domestic rolling stock safety regulation was established in the July and December on 2005. It`s been a 3 years after 2005 and to confirm whether there are some problems to applicate the regulation in the field like korail, the necessity of reviewing the regulation gains force. In this study, to improve the field application in rolling stock safety regulation, we investigated the results of integrated railroad audit system and internal safety regulation system in a train operator and also collected the opinions from train manufacturer. Then through the result of investigation and collection of the opinions, we proposed the amendment to the rolling stock safety regulation.

본 연구는 북한이탈주민 창업 활성화를 위하여 현재창업을 준비 중에 있거나 창업을 진행하고 있는 북한이탈주민 청년 창업가들의 입국 전·후의 인식과 창업교육에 대한 인식 그리고 창업 과정에 대해 심층 면담을 통하여 북한이탈주민들의 창업에 대한 인식과 창업교육 후의 인식 변화 및 창업 진행 과정에서 겪는 공통적 애로사항을 도출하여, 북한이탈주민들이 남한에서 자발적 경제활동을 활발히 할 수 있도록 현재의 정착지원제도를 고찰하여 당면한 과제를 제시했다. 아울러, 북한이탈주민 청년 창업가의 창업 과정 사례를 분석하여 자발적 경제활동 중 창업을 독려하고 이에 도움이 되고자 했다. 본 연구에서는 10명의 북한이탈주민 청년 창업가의 창업 사례를 중심으로 했으며, 아울러 창업교육을 진행하여 창업교육 전·후의 변화된 양상을 고찰하였다. 2017년 3월 기준 3만 명이 넘는 북한이탈주민들에 비하면 매우 적은 표본이지만, 각각의 창업 과정 사례는 매우 중요한 연구자료이며, 북한이탈주민들의 자발적 경제활동을 위해서는 창업을 활성화 시켜야 한다는 시사점을 도출했다. 북한이탈 청년의 창업 현장에 맞는 정착지원제도가 만들어 지도록 정책 과제(課題)를 객관적으로 도출하였다. The purpose of this study is to investigate the perception of pre-entry and post-immigrant youth entrepreneurs who are currently preparing for startup or startup business doing for the activation of North Korean defectors through in-depth interviews, The change of perception after entrepreneurial education and the common difficulties in the process of startup, and present the problem to be addressed by examining the current settlement support system so that defectors in South Korea can actively engage in voluntary economic activities in South Korea. In addition, by analyzing the case of establishment process of North Korean defectors' youth entrepreneurs, I would like to encourage and assist entrepreneurs in voluntary economic activities. In this study, we focused on the case of ten North Korean defectors' young entrepreneurs and found that they were able to see the changes before and after entrepreneurship education. Though it is a small sample compared to more than 30,000 North Korean defectors as of April 2017, each case of the establishment process is very important research material and it is necessary to activate the start-up for the voluntary economic activities of defectors. In addition, it is necessary to objectively determine the problem (settlement support system) and find its complementary point.
