교정치료 초기에 사용되는 4가지 호선의 초기 치료효과를 비교하기 위한 전향적 임상 실험 연구
unknown,Malcolm L. Jones,Luciane M. Menezes,Koo, Daniel,Carlos N. Elias 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.5
본 연구의 목적은 교정치료 초기에 사용되는 스테인레스스틸, 다가닥철선, 초탄성 NiTi, 열활동성 NiTi 재료로 이루어진 총 4가지 호선의 초기 치료효과를 비교하기 위하여 시행되어으며, 실험의 설계는 전향적 임상 실험(prospective randomized clinical trial)으로서 브라질 리오데자네이로 주립 치과대학에 내원한 45명의 고정식 교정장치 환자를 대상으로 시행되었다. 각 호선의 재료는 환자의 치열에 무작위로 배당되었는데 스테인레스스틸은 26명,다가닥철선은 22명,초탄성NiTi는 22명, 열활동성NiTi는 20명에게 할당되었고.8주후에 모형을 다시 제작한 후 3차원 디지털 영상 장비를 이용하여 모형의 치관에 설정된 해부학적 지표의 변화를 측정하였는데 치료전 및 치료후 치열불규칙지수(Dental Irregularlty Index)의 차이로 초기 교정치료 효과를 비교하였다. 분산분석을 시행하여 불규칙지수의 변화를 살펴본 결과 호선의 재료에 따른 초기 치료 효과는 유의한 차이가 나타나지 않았다. The aim of this study was to compare the clinical performance of 4 types of orthodontic wires, indicated for initial tooth alignment: stainless steel, multistranded steel, superelastic and thermoactivated nickel-titanium. A prospective randomized clinical trial was conducted on a sample of 45 patients, at the Dental School of the State University of Rio de Janeiro, Brazil. Fixed appliances were fitted and study casts were obtained from each patient. Randomly, the wires were allocated as follows: 26dental arches for superelastic NiTi wires, 22 for stainless steel, 22 for multistranded and 20 for thermoactivated archwires. After 8 weeks, the archwires were removed and impressions for study casts were taken again. Using a 3D digitization technique of defined anatomical points on the study cast crowns, a Dental irregularity Index (Dll) was created for each study cast. The difference between Dll before and after the archwire insertion expressed the aligning effect of the wires. ANOVA tests were employed to evaluate the anatomical point approximation (positive Dll) and separation (negative Dll), for each area of the dental arches: upper and lower whole arch and anterior arch. Results showed no significant difference between the different archwires.

최초의 프리츠커 건축상 수상자 Philip Johnson의 건축에 관한 연구
unknown 순천향대학교 교수학습개발센터 2005 순천향 산업기술연구소논문집 Vol.11 No.1
This study aims at the architectural characteristics and principles of Philip Johnson as the First Pritzker Architecture Prize Laureate in 1979. The purpose of the Pritzker Architecture Prize is to honor annually a living architect whose built work demonstrates a combination of those qualities of talent, vision and commitment, which has produced consistent and significant contributions to humanity and the built environment through the art of architecture. The field of architecture was chosen by the Pritzker family because of their keen interest in building due to their involvement with developing the Hyatt Hotels around the world. Architecture was also a creative endeavor not included in the Nobel Prizes. The procedures were modeled after the Nobels, with the final selection being made by the international jury with all deliberations and voting in secret. Nominations are continuous from year to year with over 500 nominees from more than forty countries being considered each year. Therefore the fact that it receives the Pritzker Architecture Prize is very glorious and honorable. With this fact with character, as the architect who represents us it researches his architecture and it searches for it does our architectural directions with essential meaning and character.

On a new land use classification and zoning scheme of Ulaanbaatar, Mongolia
unknown 순천향대학교 사회과학연구소 2004 순천향 사회과학연구 Vol.10 No.1
This paper attempts to define the current situations of the land use planning and regulation in Ulaanbaatar, Mongolia, and to draft an initial sketch of the urban land use classification and zoning system for the capital city. The major results of the research are as follows: 1. The paper examined new types of land use, emerged from the traditional land uses as well as in the course of the transition period. Field surveys were conducted to estimate the modifications and alterations of the land use structure occurred in the land use structure by the area balance. Ulaanbaatar city is divided into 13 micro regions to represent the functional zones of the city. 2. The study analyzed the primary materials on the land use of Ulaanbaatar city, and studied on trial bases the possibilities of applying the urban land use classifications of developed countries, especially those of the Republic of Korea, to the conditions of the capital Ulaanbaatar. 3. The common grounds, necessary for working out the Ulaanbaatar city zoning system, were assembled through the comparison of the urban zoning systems of such countries as Korea and USA with the conditions of Mongolia. The common grounds were assessed and conclusions were drawn thereof.
