The purpose of this study is to evaluate the features of the finishing material according to their type and color. The purpose of this in order is to improve the pleasantness of the interior, by using the proper finishing materials, in planning the interior, and to apply it to framing the prediction model for practical use in interior design, This stud was conducted by evaluating experiment manufactured with the CG(Computer Graphics). The process of the study is as follows, 1) The finishing materials used in the interior based on the previous study was classified. The color range of the selected finishing materials was examined. 2) The evaluation experiment using the CG was conducted on the basis of the selected finishing materials. 3) With that result, the evaluation properties was analyzed according to evaluating variables(that is, the finishing material, hue, value, and chroma) for the interior image. 4) Finally, the prediction model of the interior finishing materials was framed with the image type. Through the Factor Analysis of 19 Adjectives, 8 representative image types such as 「Open·Bright」, 「Gorgeous·Strong」, 「Quiet·Natural」, 「Smooth·Elaborate」, 「Coarse·Rough」, 「Elegant·Refined, 「Warm」」 and 「Cool」 were extracted. The prediction model was framed for the 8 representative image types. The 「Open·Bright」, 「Quiet·Natural」, 「Cool」images are as follows, 1) When you want to produce the 「Open·Bright」image, it is ideal to use wallpaper as finishing material and Y or B in hues. The higher the value and middle chroma you use. The bigger 「Open·Bright」 the efficiency you achieve. 2) When you want to produce the 「Quiet·Natural」 image, it is good to use woods for finishing materials, You can get a better image with the YR or R in hues, with higher value and lower chroma. 3) When you want to produce the 「Cool」image, it is better to use stones for finishing materials. Cool colors and the hue of B, PB, BG are recommended. The lower value and chroma are effective as well.

This study was aimed at investigating the psychological effect middle age people got through the health promotion program. For this perpose, it selected as subjects's total of 62 made up of 14 males and 48females attending the fitness promotion center affiliated to Korea University of Physical Education, who were living in Seoul, suburbs and small citise. The health promotion program was provided with the middle aged people with no exercise habits over the 10-week period. An attempt was made to inquire into STAI and the state of their heath conditions before and after participation in the program. As a result, the following conclusion was drawn. First, it was found that there was a difference in the subjects' STAI before and after their participation in the heath promotion program designed by this study. Especially, male subjects showed a higher level of STAI than female counterparts. Middle-aged subjects such as Saiaried persons and those engaged in other jobs showed a higher level of STAI than those such as housewives and self-employed persons. The middle-aged group living in small cites was found to have a higher level of STAI than the middle-aged group living big cities. Second, it was found that there was a difference in the state of their health conditions before and after their participation in the health promotion program. In particular, middle-aged women showed the better state of their health conditions than middle-aged men. The middle-aged persons living in big cities. But, in contrast with the case of the relationship between the persons living in big cities and those in small cities and the relationship between the middle-aged persons such as those engaged in other jobs. There was no psychological effect that the health promotion program had on the state of their health conditions. Therefore, participation in the health promotion program was found to have an effect on the state of health conditions for middle-aged persons such as housewives and self-employed persons.

본 논문에서는 128 비트 ARIA 암호 알고리듬을 소형화시킨 32 비트 하드웨어 구조를 제안하고 있다. 최근 휴대폰을 이용한 금융결제나, 노트북에서 무선 인터넷을 이용한 VPN 접속과 같이 휴대형 장치에서도 보안 서비스가 이루어지고 있다. 휴대형 장치는 제한된 크기와 전력에서 동작하기 때문에 보안서비스를 추가하기위해서는 저전력, 소형화 설계가 요구된다. 본 논문의 ARIA 하드웨어 구조는 이러한 제한된 환경에 적용 가능한 저전력, 소형 구조이다. 제안된 ARIA는 32 비트 구조이다. 소형화를 위해서 4개의 S-box와 32비트 확산 함수를 구현하였다. 또한 복호화할 때 라운드 키 생성에 필요한 확산 함수의 사용하지 않도록 데이터 패스를 수정하였다. 본 논문의 32비트 ARIA는 초기값 생성을 위해 53 클록 사이클이 필요하다. 암/복호화에는 236 클럭 사이클이 요구된다. 32비트 ARIA는 0.35 ㎛ CMOS 공정으로 13,960.5 EG로 구성되었다. This paper presents a 32bit hardware architecture for the ARIA cryptographic algorithm. Recently security service has extended on portable devices such as cellular phones and VPN with wireless Internet at laptops. The mobile units have a limited power with small size demanding a low-power and compact design. The hardware design in this paper is a low-power and compact version of ARIA for the limited mobile environment. The proposed ARIA is based on 32-bit architecture.

이유진,박수병 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.5

발치 환자의 치료에서 결과의 안정성과 심미적인 요구를 만족하기 위해서는 상악 전치의 전후방 및 수직적인 위치와 순설측 경사를 올바르게 설정하여야 한다. 상악치열에서 제1소구치를 발거하고 견치를 발치공간으로 후방이동시킨 상태에서, 호선을 이용하여 전치를 후방견인시킬때 치아의 설측 경사와 정출과 같은 부작용이 일어날 수 있으므로 이를 방지하기 위해 다양한 방법으로 힘과 모멘트의 조절을 시도하여야 한다. 치관의 한 지점에 적용되는 힘의 크기와 모멘트 비율에 따라 치근막에 나타나는 응력분포가 변화하고 이를 알아냄으로써 치아이동 양상을 예측할 수 있다. 상악 전치부에 직접 힘을 가하게 되는 J-hook headgear는 전치부의 모멘트를 변화시키는 효과를 제공하므로, 본 연구에서는 호선의 전치부에 각각 다른 토오크를 부여하고 각 상태에서 J-hook headgear를 후상방으로 적용하였을 때 모멘트 변화에 따른 응력분포의 변화를 광탄성법으로 관찰하였다. 치조골 부위를 광탄성 레진으로 대체한 모형을 제작하고 인공 치아에 .022" slot의 standard edgewise bracket을 부착하였다. 측절치 bracket원심 1mm지점에 높이 7mm의 vertical loop을 가지는 호선을 .020"X.025" stainless steel wire로 제작하였으며 중절치와 측절치 사이에 high pull J-headgear를 위한 hook을 납착하였다. 전치부에서 0。, 7。, 14。의 토오크를 가각 부여한 뒤, loop을 1mm activation하였을 때 나타나는 응력분포와 각각에 high pull J-hook headgear를 교합면에 대하여 후상방 35。방향으로 200mg의 힘을 적용 했을때의 응력분포를 비교하였여 다음과 같은 결과를 얻었다. 결론 1. 0。토오크에서는 치근의 치근단측 1/2부위에 응력이 분포하였으나 순측에 비해 설측이 약하고 좁게 나타났고 특히 치근단에 집중된 응력은 순, 설측 모두에서 high pull J-hook headgear의 사용으로 감소하였다. 2. 7。토오크에서는 치근면을 따라서 응력이 분포하는데, 순측으로는 치조정에서부터 나타나는 응력이 치근면을 따라서 치근단측 1/3부위까지 점차 폭이 좁아졌고, 설측은 순측보다는 약한 응력이 치근의 치관측 1/3에서부터 차근단까지 나타났다. 치근단에서는 순측보다 설측이 더 강하게 나타났고, high pull J-hook headgear의 사용으로 전반적으로 응력의 크기와 폭의 증가가 있었다. 3. 14。토오크의 호선에서는 7。토오크의 호선과 분포하는 응력의 양상은 유사하지만 좀 더 강하게 나타났고, 순측에서는 치근면의 중앙부위가 폭이 가장 넓게, 설측에서는 순측에 비해 균일한 폭으로 응력이 분포하였다. 치근면을 따라서 나타나는 응력은 headgear를 사용하는 것이 사용하지 않은 경우보다 강하였고 순측보다는 설측이 더 강하였다. headgear를 사용하였을 때 치근단의 응력 집중은 순측에서보다 설측에서 더 크게 나타났다. This study was designed to investigate the stress intensity and distribution produced by 1mm activation of retraction archwire with 0。, 7。, 14。 torque and application of high pull J-hook headgear during retraction of four maxillary incisors using the photoelastic stress analysis. The photoelastic model was made a PL-3 type epoxy resin which was substituted by alveolar bone portion. Each retraction archwire was fabricated from .020"X.025" stainless steel wire which had vertical loops in 7mm height and hooks for high pull J-hook headgear between central and lateral incisors. The high pull J-hook headgear was applied 35 degree backward and upward to occlusal plane with 200gm per each side. The findings of this study were as follows: 1. In case of 0。 torque, the stress was distributed from cervical 1/3 to apex of roots of central and lateral incisors which were the forms of arc mode. When the high pull J-hook headgear was applied, the stress distributed by arc mode was presented from cervical 1/2 to apex of roots of central and lateral incisors. And the stress distributed by following the root surface was presented from alveolar crest to cervical 1/2 of roots of central and lateral incisors. The stress between apecies of central and lateral incisors was presented also. 2. In case of 7。 torque, the stress distributed by arc mode was presented from cervical 1/2 to apex of roots of central and lateral indisors. And the stress distributed by following the root surface was presented from alveolar crest to cervical 1/2 of roots of central and lateral incisors. When the high pull J-hook headgear was applied, the stress distributed by following the root surface was presented more apically than without headgear. The stress between apecies of central and lateral incisors was presented also. 3. In case of 14。 torque, the stress distributed by following the surface was presented from alveolar crest to apex of roots of central and lateral incisors. When the high pull J-hook headgear was applied, the stress distributed by following the root surface was presented stronger than without headgear. The stress between apecies of central and lateral incisors was presented also.

Dislocation is one of the serious complications in total hip replacement arthroplasties. The purpose of this study is to evaluate the risk factors of dislocation, including age, sex, preoperative diagnosis and bilaterality, history of previous hip surgery, positioning of component, soft tissue tension, treatment after dislocation or redislocation. Authors reviewed 190 patients of total hip replacement arthroplasty, which were performed from Jan. 1990 to Dec. 1996. 15 cases developed dislocation after surgery. Incidence of dislocation was 7.89%(15 of 190 cases). Dislocation after revision was not happened(0 of 18 cases). Inclination of acetabular cup was average 37.5° (range: 31° - 43° ). Average anteversion of the acetabular component was 18.1" by Woo and Morrey method, 11.4° by Hassan method. They were normal range except 3 cases. Dislocation was not prevented even though inclination and anteversion of acetabular cup were within normal range. Soft tissue tension is determined by change of limb and femoral neck length. Average limb length difference was -0.2mm(range; -l0mm - +10mm) and average offset difference was +1.7mm(range;-4mm - +18mm). Revision must be accomplished as soon as possible when limb shortening happen by upward migration of the acetabular component. In conclusion, anteversion of acetabular cup may be most important factor in our cases, so cup position must be fixed in proper position during operation.
