The purpose of this study was to investigate the policies related to residential remodeling for elderly households of Korea and Japan. Documentary research methodology was used in this study. The major results of this study are as follows: 1) It is not enough that the housing policy of elderly households prepare institutions and standards for aging society in Korea. 2) Residential remodeling projects by this time were not to improve residential environment of elder]y households but to support only a few low income elderly households in Korea. 3) Housing policy of elderly households consisted of design and remodeling standards for barrierfree of new housing and housing stock, housing financing, human resource network, and educational program of housing remodeling in Japan. 4) Central government and local self-governing body have support system which is systematic and that is helpful to those elderly households who needs housing remodeling in Japan. 5) It is needed that local self-governing body frame a policy of residential remodeling for elderly households. And central government and local self-governing body prepare the policy of financial support and contents of residential remodeling for elderly households according to the level of housing quality and residents circumstances. And they have the education system for specialist of residential remodeling for elderly households and clarify the standards of residential remodeling for elderly households. 6) In-depth analysis study is need to find a suggestion in many cases of advanced nations.

The purpose of this research is to evaluate the health performance of existing buildings which completed green remodeling using the WELL Building Standard developed by Delos in the USA. The features and the level of improvement in health were examined and the results were as follows. As a result of comprehensive evaluation of the health performance of the target building, the health performance after green remodeling improvement was improved by 17.3% compared to before green remodeling. As a result of applying the alternatives for improving health performance, improvements were 22.9% by Alternative 1, 28.8% by Alternative 2, and 28.7% by Alternative 3. If the improvement ratio with respect to the construction cost were compared, Alternative 1 was the best followed by Alternative 2. Finally, the cost effectiveness of improving health performance against construction cost were best in the order of self-closing door installation, airtight seal, and pest inspections.

The size of the home interior market is growing rapidly as interest in interiors and self-interiors has increased due to the recent rapid increase in single-person households. Most of the Bathroom remodeling is done by requesting an offline interior contractor and then visually checking it in the final completion stage, so it is not easy to re-construct even if the customer is dissatisfied. Therefore, this study developed an immersive virtual reality-based Bathroom self-remodeling system that can visually check space and design from the design stage to the final stage by incorporating VR technology to feel realistic in virtual reality. The bathroom structure may select the basic structure of the predefined bathroom space or freely set the size of the bathroom space. For furniture items, you can choose the washbasin, toilet, bathtub, shower booth that are essential elements of the bathroom and others(mounting rack, trash bin, handle). The tile texture may change the texture of the selected tile at a desired wall position by selecting various textures. In particular,, the texture of the wall tile can be varied by selecting horizontal, vertical and inclined directions at the desired angle according to the needs of the user and the contractor. As a future research project, this system will enable indoor sharing between users who are physically far away in real-time, allowing direct experience in virtual spaces, connection to purchases, and request estimates.

Objective: The aim of this study was to evaluate the strain induced in the cortical bone surrounding an orthodontic microimplant during insertion in a self-drilling manner. Methods: A 3D finite element method was used to simulate the insertion of a microimplant (AbsoAnchor SH1312-7, Dentos Co., Daegu, Korea) into 1 mm thick cortical bone. The shape and dimension of thread groove in the center of the cortical bone produced by the cutting flute at the apical of the microimplant was obtained from animal test using rabbit tibias. A total of 3,600 analysis steps was used to calculate the 10 turns and 5 mm advancement of the microimplant. A series of remesh in the cortical bone was allowed to accommodate the change in the geometry accompanied by the implant insertion. Results: Bone strains of well higher than 4,000 microstrain, the reported upper limit for normal bone remodeling, were observed in the peri-implant bone along the whole length of the microimplant. Level of strains in the vicinity of either the screw tip or the valley part were similar. Conclusions: Bone strains from a microimplant insertion in a self-drilling manner might have a negative impact on the physiological remodeling of cortical bone.

Recently, residents' community center is trying to combine with various program and facilities as the residents self-government program's development. This is due to the reduction of administrative tasks, the computerization of programs, the importance of community participation activities, the activation of community, and the increase of welfare projects. Therefore, previous studies on program complexity have been actively carried out. Nevertheless, spaces and programs studies of considering regional characteristics are lacking. Therefore, the community centers' program and spaces need to change. Therefore, this study propose an improvement direction through analyzing the situation of the residents' community center. For this study, the precedent research and institutional limitations are examined. In addition, this study selected and analyzed the 15 local community center. Thirdly, interviews were conducted with users and officials of the 5 residents' community centers on major changes. Finally, This study suggests direction of program improvement and architectural design direction. As a result of this study, integrated management measures with overlapping agencies should be sought. Surplus space will have to be rearranged into a new program through prior examination. Above all, the proposed remodeling guidelines require user requirements to be reflected and designed with the residents.

In this building, we never use the existing construction methods such as disassembly, destruction and newly construction to ensure the eco-friendly building and to decrease of waste disposal. We make customers feel newly by using minimum materials, pursuing the 'Best Design Using Lower Material' slogan and remodeling the building partially. The line is the most informal type one which is lack of intention. This line formation is harmonized with self-efficiency and completeness that are not required for unnecessary things, and simple unification which has not alternatives or obstacles.

Purpose: The goal of this study was to investigate the histomorphometric characteristics of the healing process of microcracks in the cortical bone after the installation of mini-implants (MIs). Methods: Self-drilling MIs were inserted into the tibial diaphysis of twelve adult male New Zealand rabbits. Four MIs per rabbit were placed randomly. The animals were divided into four groups according to the length of the healing period: group A was sacrificed immediately, group B was sacrificed after one week, group C was sacrificed after two weeks, and group D was sacrificed after four weeks. Cortical bone thickness was measured using micro-computed tomography, and histomorphometric analyses of the cumulative length of the microcracks (CLCr) and the total number of microcracks (NCr) were performed using hematoxylin and eosin staining. Results: The microcracks were radially and concentrically aligned in the peri-MI bone. The CLCr decreased significantly one week after the surgery, mainly due to healing of the concentrically aligned microcracks. The CLCr showed another significant decrease from two weeks after the surgery to four weeks after the surgery, mainly reflecting healing of the radially aligned microcracks. A statistically significant decrease in the NCr occurred as the microcracks healed from zero weeks to two weeks. However, no significant difference in the NCr was found between groups C and D. Conclusions: In order to improve the primary stability of MIs, delayed loading and a healing period of a certain length are recommended to ensure the optimal healing of microcracks and bone remodeling.

It is undeniable that urban greenspace is the soul of a city. Conventional urban greenspace such as parks, community gardens, playgrounds etc. located within a city reduce the negative effects of pollution, play a major role in the survival of the urban ecosystem, and promote healthy lifestyles. Today, 55% of the world's population lives in urban areas, which is expected to increase to 68% by 2050. Projections show that urbanization and the gradual migration to urban areas combined with the fast growth of the world's population, could add another 2.5 billion people to urban areas by 2050 and almost 90% of this increase will take place in Asia(UN, 2018). As a result, many plots in the cities are and will continue to be occupied with buildings to provide residential support to the increased population. This will dangerously decrease urban greenspaces. Moreover, worldwide, food crisis, energy crisis, and social crisis is posing a great threat to the existence of mankind. Additionally, the COVID - 19 has introduced a new lifestyle where from work culture to community configuration has drastically transformed. In this scenario, residential buildings will have to serve more than just providing privacy and shelter. As urban greenspaces are being occupied by concrete residential buildings, these buildings will have to compensate for the percentage of urban green they are destroying and the issues they are imposing in the process. The goal of this thesis is to design, architecturally define and, categorize comprehensive 'sustainable Greenspace'(S.G.S) for the multi-family housing scenario. These will be different than the conventional green (veranda, rooftop green) we commonly see in residential buildings. An old, dilapidated apartment building will be the target of remodeling to fulfill the purpose of this thesis.

Waterproofing is one of the important factor to improve performance of building elements. But existing repair system for waterproofing have many problems like a damage of waterproof layer due to movement of concrete substrate, blistering effect and moisture condition. So waterproofing layer can not play an important part to improve waterproofing function and performance of building. Therefore, new waterproofing system to solve these problems of existing waterproofing system is developed. In this paper, new waterproofing system in water-leakage repair for remodeling is introduced

This study is to reveal the multi-generations' cohabitation and housing conditions are necessary for each generations to take over the homelike interchange as maintaining the excessive self-support. The subjects of this survey were 151 men and women over 60 years and older in Mokpo. The survey revealed that most or the people owned their own homes, and in many cases that the parents bought the home. There are many cases in which parents have been living with their own homes, and in many cases that the parents bought the home. There are many cases in which parents have been living with their children's families, since their children got married, and there many people who think that cohabitation is natural. In the aspect of living, the families normally eat together but there is a separation in economy and entertainment. There are many renovation and remodeling of a house to adjust the situation of three generations' cohabitation.About 70% of people experience problems with cohabitation. In particular, many cases involve the
