According to the 2005 Korean census, the 65 and over population now exceeds 9.5% of the total population and is growing rapidly. Meeting elderly environment and care needs of this rapidly growing segment of the population becomes a major challenge for public policies and planners. Since great deal amount of elderly will reside in their houses, aging in place concept becomes important. For the success of aging in place, the quality of individual house unit, community support systems, and/or quality of senior center of the community are crucial. Since elderl environments and facilities serve not only medical and/or care programs but also social activity program in aging society, senior centers need to promote social activities and other care programs. The purpose of this study is to analyze characteristics of environmental affordance of a well received senior center in Tokyo, Japan. In order to analyze the characteristics, Murtha & Lee user benefit criteria and Lawton's environmental affordance approaches were used. As results, design characteristics and interior elements which provide environmental affordance were enumerated by type of space. Based on needs and user benefit criteria, those features were analyzed. This study shows design characteristics, elements, and attributes which are well received and utilized by elderl users.

Today, almost all families are quipped with computers. At the same time, we can find lots of side-effects because of computers. If young students, who tend to be unable to control their impulses once they are immersed in internet, the problem will be more serious. It could be happened that the young students can't distinguish the real from the image. Therefore, it is important to grasp the actual condition of juvenile Internet addicts and their practical life, and to come up with basic materials necessary for working out countermeasures. This study surveyed 339 high school students from three high schools in the area of Seoul. Data collection were collected from 22nd of December, 2003 to 27th of December 2003. The collected data were analyzed by SPSS program using T-test, ANAVA and Pearson correlation coefficient. The results were as follows: First, of the 333 respondents 9.61% of them were high-risk internet using group, 15.02% of them were potential-risk internet using group. 25% of then were identified as addicted group. Second, the more addicted the subjects are, the lower their level of school adjustment becomes. For the addicted group, it is difficult to adjust their school and to have a good relationship with friend. Third, the more addicted the subjects are, the lower their level of friendship becomes. The subordinate areas of friendship have same results as the level of Internet addiction and the extent of friendship. If students are addicted to Internet, it is difficult to find friends who can give them encouragement in practical life. Firth, there was a negative relationship between Internet addiction and school adjustment, and, there was a negative relationship between Internet addiction and friendship. Through this study we have seized the relationship between Internet addiction and school adjustment and friendship. As a result, the more addicted, the more difficult to adjust to school. And for the students who were addicted, it is difficult to make a friend.

PURPOSE. To analyze the stress distribution of the implant and its supporting structures through 3D finite elements analysis for implants with different hexagon heights and to make the assessment of the mechanical stability and the effect of the elements. MATERIALS AND METHODS. Infinite elements modeling with CAD data was designed. The modeling was done as follows; an external connection type ∅4.0 mm×11.5 mm OsstemUSII (Osstem Co., Pusan, Korea) implant system was used, the implant was planted in the mandibular first molar region with appropriate prosthetic restoration, the hexagon (implant fixture’s external connection) height of 0.0, 0.7, 1.2, and 1.5 mm were applied. ABAQUS 6.4 (ABAQUS, Inc., Providence, USA) was used to calculate the stress value. The force distribution via color distribution on each experimental group’s implant fixture and titanium screw was studied based on the equivalent stress (von Mises stress). The maximum stress level of each element (crown, implant screw, implant fixture, cortical bone and cancellous bone) was compared. RESULTS. The hexagonal height of the implant with external connection had an influence on the stress distribution of the fixture, screw and upper prosthesis and the surrounding supporting bone. As the hexagon height increased, the stress was well distributed and there was a decrease in the maximum stress value. If the height of the hexagon reached over 1.2 mm, there was no significant influence on the stress distribution. CONCLUSION. For implants with external connections, a hexagon is vital for stress distribution. As the height of the hexagon increased, the more effective stress distribution was observed. 연구 목적: 본 연구는 hexagon 높이에 따른 임플란트 각 부위와 주위 지지조직의 응력분포를 3차원 유한요소 해석을 통해 평가하여 hexagon 높이가 기계적 안정성에 미치는 영향을 평가하고자 시행되었다. 연구 재료 및 방법: 외측 연결 형태의∅L4.0 mm×11.5 mm USII (Osstem Co., Pusan, Korea) 임플란트 시스템을 이용하여 하악 제 1대구치 부위에 임플란트를 식립하여 보철 수복한 경우를 연구 모델로 가정하고 임플란트 고정체의 외측 연결부인 hexagon의 높이를 각각 0.0 mm, 0.7 mm, 1.2 mm, 1.5 mm로 적용한 CAD data를 유한요소 모형화하였다. ABAQUS 6.4 (ABAQUS Inc., Providence, RI, USA)를 이용하여 산출된 응력 값 중에서 등가응력을 기준으로 각 요소(상부 치관, 지대주 나사, 고정체, 치밀골, 해면골)에서 나타나는 최대 응력 값을 비교 하였다. 결과:외측 연결을 갖는 임플란트의 hexagon의 높이는 고정체, 지대주 나사, 상부 보철물 그리고 주위 지지골에 대해 응력 분산에 영향을 주었다. Hexagon의 높이가 증가할 수록 임플란트의 응력 분산은 더 잘 이루어졌으며, 최대 응력 값의 감소를 보였다. Hexagon의 높이가 1.2 mm 이상이 되면 응력 분포에 더 이상 크게 기여하지 않았다. 결론: 외측연결을 갖는 임플란트에서 hexagon은 응력 분산에 필수적인 요소이며 그 높이가 증가할수록 더욱 효과적인 응력의 분산이 나타났다.

PURPOSE. The accuracy of a gypsum model (GM), which was taken using a conventional silicone impression technique, was compared with that of a polyurethane model (PM), which was taken using an iTero™ digital impression system. MATERIALS AND METHODS. The maxillary first molar artificial tooth was selected as the reference tooth. The GMs were fabricated through a silicone impression of a reference tooth, and PMs were fabricated by a digital impression (n=9, in each group). The reference tooth and experimental models were scanned using a 3 shape convinceTM scan system. Each GM and PM image was superimposed on the registered reference model (RM) and 2D images were obtained. The discrepancies of the points registered on the superimposed images were measured and defined as GM-RM group and PM-RM group. Statistical analysis was performed using a Student’'s T-test (α=0.05). RESULTS. A comparison of the absolute value of the discrepancyrevealed a significant difference between the two groups only at the occlusal surface. The GM group showed a smaller mean discrepancy than the PM group. Significant differences in the GM-RM group and PM-RM group were observed in the margins (point a and f), mesial mid-axial wall (point b) and occlusal surfaces (point c and d). CONCLUSION. Under the conditions examined, the digitally fabricated polyurethane model showed a tendency for a reduced size in the margin than the reference tooth. The conventional gypsum model showed a smaller discrepancy on the occlusal surface than the polyurethane model.

As the world population is aging, especially in advanced countries, the paradigm of the environmental plan has been changed. Rapidly growing baby-boomer population has altered the concept of aging friendly environment, because this generation with material prosperity, unlike previous generations, is pursuing various lifestyles, and life values. Along with these, the development of today’s science technology and cultural change has accelerated these demands. In Korea, there is no accumulated experience of developing and managing the aging friendly environment, and accordingly, some developments in Korea were more likely to follow the former experience of developed countries. Since the environment for our reference has changed so fast, it is necessary to read this changing trend for developing right one for Korean. Therefore, the purpose of this study is to find out current concept of the aging friendly environment changes. For this purpose, a qualitative method was used by analyzing the contents presented at a latest leading conference on Environment for Aging which is a gathering field of live information on current trend. The data were collected through visiting conference, recording presented contents, collecting relevant publication, and interviewing as needed. The analysis was conducted by extracting keywords and connecting them to grasp the current trends. As a result, this study found several current trends; combining green design strategy with elderly living environment, pursuing diverse way of social mix, and emphasizing Evidence Based Design. These trends imply the necessity of the change in the developmental direction of Korean elderly housing, preventing the conventional trial and error otherwise expected.
