Implementing a home modification to enable elderly's safe and independent living is the key plan to realize their aging in place. South Korea in which had entered an aged society is not yet vitalized in home modification for the elderly compared to that of welfare-developed countries, and South Korea provides support that is limited to the low-income elderly. Therefore, this purpose of this study was to analyze the laws related to the home modification, the present condition of home modification support, the standards and guidelines in home modification, the support in house modification cost, and supporting organization and working force in the home modification. Through the analyzing process, this study examined the current situation and problems of institutional support in the home modification for elderly and the proposed plan for institutional improvement. The suggestions based on the results are as in the following. 1) Home modification support law(act or regulation) is required to be improved 2) Home modification support system correspondent to aging process should be provided regardless of their income levels. 3) Delicate plan standard and guideline are necessary for a process of implementing the home modification for the elderly. 4) Information on life behavior is in need for the implementation of elderly-customized home modification. 5) Cost for the home modification should be considered to cover by the Act on Long-Term Care Insurance for the Aged. 6) Housing Welfare Center and Housing Welfare Professional should be actively utilized for the home modification support institution and work force.

There is a growing interest on and expansion of rights of people with disabilities. Among them, people with visual impairment show high adaptation to environments in comparison to people with other types of disabilities, thus a large percentage of them live in their own houses rather than residing in a care facility. According to the housing status of people with visual impairment, the ratio of their residence in rural areas is high. In rural areas people who have disabilities often live in poor residential environments, requiring much improvement. However, such improvement is too costly for them to pay, and home modification that does not fully consider the user, may cause less efficiency and another dangerous situation to people with disabilities. The purpose of this study is to delineate empirical lessons for direction of customized home modification for people with disabilities through analysis of process of home modification including the execution as a intervention. This study used qualitative method to examine and analyzed the entire customized home modification process. The conclusion of this study is as follows. First, home modification measures should be derived considering the suitability of the target building for the specific condition of residents. Second, discussions with various stakeholders from the early stage during which proper home modification measure is searched are essential for realizing appropriate customized home modification. This study has significance in that it provides the direction for customized home modification for people with disabilities as well as empirical data that could reduce trials and errors in the future.

Digestive enzymatic compositions and activities in digestive diverticula of the three species of bivalves were investigated in this study. Mytilus galloprovincialis, Saxidomus purpuratus and Tegillarca granosa which were collected from southern coast of Korea on November 2010, were used for analysis. Amylase and cellulase occupied approximately 95% of digestive enzymes in digestive diverticula of M. galloprovincialis, S. purpuratus and T. granosa. The amylase and cellulase activities were 2.6 and 0.8 U/mg in M. galloprovincialis, 2.4 and 8.8 U/mg in S. purpuratus and 7.3 and 11.8 U/mg in T. granosa. And protease activities in digestive diverticula of M. galloprovincialis, S. purpuratus and T. granosa showed the lowest values to 0.00019, 0.00028 and 0.00022 U/mg, respectively.

The aim of this study was to investigate the role of osteal macrophages (osteomac) and osteocytes in bone remodeling using a mathematical model. We constructed the bone system with pre-osteoblasts, osteoclasts, osteocytes, and osteomac. Each link of the parameters and ordinary differential equations followed the Graham's model in 2013 except for the parameters of osteomac signaling and osteocytes signaling to link preosteoblasts and osteoblasts. We simulated the changes in each cell and bone volume according to the changes in the parameters of osteomac signaling and osteocytes signaling. The results showed bone volume was unstable and decreased gradually when the effectiveness of osteocytes and osteomac dropped below a certain level. When the parameters of osteomac signaling and osteocytes signaling to link preosteoblasts and osteoblasts had a value less than 1, bone volume increased with the increase in the parameter of osteomac signaling to link preosteoblasts and osteoblasts. Moreover, although the parameter of osteocytes signaling to link preosteoblasts and osteoblasts, increased in case of a small parameter of osteomac signaling, bone volulme decreased. If the parameters of osteomac signaling to link preosteoblasts and osteoblasts were over a certain level, bone volume was positively maintained, despite the parameter of osteocyte signaling to link preosteoblasts and osteoblasts. We suggested the osteomac may affect bone remodeling and may play an important role in bone cell network.

Supersonic/Hypersonic wind tunnel is a facility which is intended to test and to observe the physical phenomena around a model by creating supersonic flow in the test section. In designing an airplane, the wind tunnel test is demanded to analyzing aerodynamic characteristics of the model without making a prototype. In this research, the model aerodynamic facility(MAF) is modified for the purpose of increasing running time and its functionality. New pneumatic valves for remote control was installed for safety requirement, and new air tanks was installed on MAF as well. A pipe system is also modified to use those new valves and tanks, and the ceiling and side glasses of the test section are switched to ones with the larger surface area. After the MAF modification, a test is performed at Mach 2, 3 and 4. In this test, shadow graph technique, one of the flow visualization methods, is used to visualize supersonic flow field. The pressure in the settling chamber and working section at Mach 2, 3 and 4 was measured in each case. As a result, the possible model size and running time are obtained.

The existing NATM (New Austrian Tunneling Method) has induced civil compliants due to blasting vibration and noise. Machanized excavation methods such as TBM (Tunnel Boring Machine) are being adopted in the planning and construction of tunneling projects. Shield TBM method is composed of repetition processes of TBM excavation and segment installation, the machine has to be stopped during the later process. Consecutive excavation technology using helical segment is under developing to minimize the stoppage time. The modification of thrust jacks and module are planned to ensure the advance force acting on the inclined surface of helical segment. Also, the integrated system design of hydraulic circuit will be remodeled. This means that the system deactivate the jacks on the installing segment while the others automatically act the thrusting forces on the existing segments. This report briefly introduces the mechanical research part of the current consecutive excavation technological development project of TBM.

This study is focused on the residential spaces that the elderly wish to renovate and their willingness to improve residential environment as they grow old. The analysis shows, first, the most inconvenient places as they grow old are the stairs, following by the toilet and the bath. Second, the place that the elderly most wish to renovate is the floor, upgrading floors with non-slippery materials. And they wish to remove the height differences on the floor to protect them from tripping over, upgrade the floor plan for their convenience and renovate the storage and working spaces at the kitchen and dining areas. The more the government supports the costs of the residential renovation service, the more the elderly are willing to use the renovation service. The factors influencing their willingness to residential renovation are health, residential environment, experience to accidents and their allowances. The elderly who experienced accidents inside their residence are more willing to renovate their house. Even though the elderly wish to renovate their houses, it's not carried out due to the financial difficulties and the lack of information. Thus, the government should share the useful information about residential renovation for the safety of the elderly and find a way to raise money to cover the costs of the renovation.
