Recently, various composite materials for additive manufacturing are interested to expand the application field of 3D printing. 3D printing technique was mainly developed using polymer, and ceramic materials for 3D printing are still in the early stage of research due to the requirement of high solid content and post treatment process. In this study, silica particles with various diameters were surface treated with silane coupling agent, and synthesized as silica composite with photopolymer to apply DLP 3D printing process. DLP is an additive manufacturing technology, which has high accuracy and applicability of various composite materials. The rheological behavior of silica composite was analyzed with various solid contents. After DLP 3D printing was performed using silica composites, the printing accuracy of the 3D printed specimen was less than about 3 % to compare with digital data and he bending strength was 34.3 MPa at the solid content of 80 wt%.

Housing environment for human beings has been diversified and more convenient due to the development of high technology and civilization brought by industrialization in the 20th century. In the 21st century, how to overcome the ecological limit of biased development-centered advancement, that is, how to preserve and hand over a clean and healthy 'sustainable environment' to our next generations has been one of the most-talked about issues. Environmental symbiosis means a wider range of environmental harmony from micro-dimensional perspective to macro one. The three goals of a environmentally friendly house are to preserve global environment, to harmonize with the environment around, and to offer a healthy and comfortable living environment. From the point of view of environmental symbiosis, houses should be designed to save energy and natural resources for preservation of global environment, to collect such natural energy resources as solar heat and wind force, to recycle waste water, and recycle and reduce the amount of the waste matter. Now, the environmentally-friendly house became a new social mission that is difficult to not only challenge but also realize without conversion to a new paradigm, ecologism.

본 연구는 미국 소재 T 대학교의 학생아파트를 대상으로 하여 창밖으로 보이는 외부 환경의 차이와 거주자의 환경조절 행태 사이의 관계를 분석하는 관찰연구로 진행되었다. 거주자와 거주환경간에 발생하는 부조화는 환경 스트레스의 한 원인이 된다. 이러한 환경 스트레스에 대한 대응 전략으로 거주자는 그들의 환경을 조정하곤 한다. 본 연구는 실내에서 식물을 키우거나 거주자의 취향에 따라 커튼을 교체하는 등의 환경조절 행태를 분석의 대상으로 한다. 창문과 현관 영역에서 발생하는 환경조절 행태의 정도를 비교 관찰하기 위해 군집형과 일자형으로 되어 있는 두 개의 배치 유형을 연구의 대상으로 선정하였다. 군집형 유형(cluster type: type A)은 상대적으로 도로에 가깝고 거실 창문의 조망이 다른 건물에 가로막혀 있으며, 일자형 유형(parallel type: type B)은 가로막고 있는 건물이 없어 자연경관을 거실 창문을 통해 조망할 수 있는 배치상의 두드러진 차이점이 있다. 관찰연구를 통해 군집형 유형에서 일자형 유형보다 더 높은 빈도로 식물 화분과 개별 커튼 등을 이용한 개인적 환경조절이 이루어진 흔적이 발견되었다. 이러한 결과는 창문을 통해 보이는 외부 경관의 특성이 거주자의 환경조절 행태에 미치는 영향의 정도를 암시하고 있다. 결론적으로 관찰연구에서 나타난 거주자의 환경조정 행태를 반영하여 디자인 고려사항을 제안하였다.

In the world, most of the metal technologists were as called as adornment artists than other field of industrial arts strongly industrial characters functional materials and manufacturing technology many used in the present age. In the study, one of adornments researched and material character analyzed about Art Clay Silver. The shrinkage rate of shape was about 0.24%. A shrinking phenomenon drying time thought of evaporation of water linking bonding agents and powders. After calcination of Art Clay Silver, the EDX used that just Ag 100% analyzed a result from the surface assay in the room temperature. A binder with powder in the room temperature considered to disappear, because it was been fume and smoke at high calcined temperature. A study showed when handicrafted necklaces make by these characteristic as using in difficult and delicated operations rather than naturally and beautifully expressive products.

This study is aimed at reviewing how the Orientalism trend is expressed in the modem fashion in terms of silhouette, color, materials, and detail. To this end, the geographic scope of this study is limited to China, Japan, Korea, while data are collected from fashion collections, domestic and foreign magazines since 2000's, literature, and internet sites. The results of this study can be summarized as follows: 1.

Color: due to the influence of the Oriental Zen thought, color trend seems to pursue simplicity rather than complexity, and natural aesthetics. In addition, the Oriental colorfulness shall not be ignored. 3. Materials: golden embroidered material, polished satin, jersey, tough or rough materials, etc. have used with materials of the Oriental traditional costume came into fashion. In pattern, the Orientalism trend is expressive of pattern by Chinese ink-spread technique, simple brush touch technique, cloud pattern, lotus flower pattern or dragon pattern, all of which feature the Oriental calm aesthetics or those motivated by the Oriental traditional patterns. 4. Detail: the techniques of handicrafts and manual arts such as meticulous embroidery, tassel or patchwork reflect well the Orientalism trend in the modem fashion.

The population of the elderly is rapidly increased because maturation of the social welfare system and development of medical technology. However, welfare environments for the elderly are poor either in its quality or its quantity. The aims of this study is to confirm the space improvement possibility to change the Gyung Ro Dang to the senior life support center as a community welfare service network. This study is done by the comparative analysis between existing Gyung Ro Dang in korea and former cases in Japan based on the elderly's facility preference. The facility's space reprogramming alternative from that analysis is applied to change the Gyung Ro Dang to a network facility for the regional senior life support. Afterward, it is proposed that first, facilities should be expanded scale by the new education and health improvement facilities functional room that the modern elderly need. second, Facility space will be reconstitution because the Gyung Ro Dang have to be extended it's role as a community welfare network.

The purpose of this study was to clarify residential satisfaction of the Living Environment according to responses of staffs in the Horsing Homes. For this, the data about residential satisfaction of the Living Environment of elderly with dementia were taken from the staffs in 2 nursing homes in Tokyo by the questionnaire. Additional information was collected by interviews and observation. It was impossible that the elderly with dementia answered their satisfaction and needs of spaces. For this reason, staffs who care the elderly with dementia during 24 hours and interact with the elderly with dementia were selected the subjects of this survey. Survey question asked for the general features of the staffs, satisfaction, dissatisfactory spaces and the reasons about dissatisfaction of the elderly with dementia. The data were analyzed using the frequency, percentage, crosstab, paired t-test with SPSS 11 program. The result of this study was as follows. First, most of the elderly with dementia were unsatisfied with their bedrooms and bathrooms in bedrooms. Second, the unsatisfied spaces among the living environment were bedroom, bathroom in bedroom, dining room, day corner, special activity room, common bathroom with mechanical bath, and dressing room. The reasons of the unsatisfied spaces were size, comfort, non-existence of the space, and noise in the space.

The purpose of this study was to analyze spatial composition of elderly skilled nursing facility and to provide basic information for setting up the detail facility architectural guidelines. The results of the study were following: the residential spaces of the facilities in this study were more or less overcrowded since their capacity were more than 5 elderly residents. The dimensions of some residential spaces did not even come up to the standard of elderly welfare law in force. On the other hand, the facilities had a tendency to use a space with multiple purposes or to allocate a space but to leave it with no use. Moreover comparing with the 1st floor, which was mainly for the staffs and had enough space to spare, the upper floor which was for the elderly residents, was crowded with nursing staffs and elderly residents and had densely closed residential and public spaces. For the problem solving, law and regulation modification is needed according to the case study about the usage and using frequency of each facility space. And the crowded area for the elderly residents could be enlarged through the reduction(or combination) of the rarely used spaces and moving a few residential spaces into the 1st floor.
