The purpose of this study is to propose prototypical plans for a dwelling unit applying the concepts of 'open housing' and 'aging in place' for senior citizens living in cities focusing on specific life patterns with chronic disease. Especially, a unit was designed for diabetes patients because diabetes, a representative disease of elderly people, often accompanies complications such as arthritis and Alzheimer disease. A unit design suitable for the convenient life of the elderly people with diabetes will provide a guideline for the similar unit designs of the senior citizens with other diseases. In this study, three types of unit plan are proposed. A-type plan is for type-1 diabetes patients, B-type alt.1 for the independent seniors of type-2 diabetes patients, and B-type alt.2 for the dependant seniors of type-2 diabetes patients. And a support design for a unit plan with the exclusive area of $60\;m^2$ is proposed. The same support design is used for all three unit types. Although the locations of bathroom and storage room are fixed and the location of the kitchen is changeable only in wet-zone. In conclusion, senior residents with diabetes can choose one of three unit types before occupation and the chosen unit type can be renovated by replacing infill systems as the health condition or life style changes.

In this paper, we detect and track vehicles by type based on highway daytime driving videos taken with black boxes for vehicles. In addition, we design a real-time MR contents production method that can be newly created by placing substitute videos of each type of detected vehicles in the same location as the new background video. To detect and track vehicles by type, we use the YOLO algorithm. And we also use the mask technique based on RGB color for substitute videos of each type of vehicles detected. The size of the vehicle substitute videos to be used for MR content are substituted by the same size as the area size of the detected vehicles. In this paper, we confirm that real-time MR contents design is possible as a result of experiments and simulations and believe that It will be usefully utilized in the field of VR contents.

There are various ICT technologies continuously being developed to reduce damage by industrial accidents. And research is being conducted to minimize damage in case of industrial accidents by utilizing sensors, IoT, big data, machine learning and artificial intelligence. In this paper, we propose a design method for a smart device capable of multilateral communication between devices and smart repeater in the communication shaded Areas such as closed areas of industrial sites, mountains, oceans, and coal mines. The proposed device collects worker's information such as worker location and movement speed, and environmental information such as terrain, wind direction, temperature, and humidity, and secures a safe distance between workers to warn in case of a dangerous situation and is designed to be attached to a helmet. For this, we proposed functional requirements for smart devices and design methods for implementing each requirement using sensors and modules in smart device. And we derived evaluation items for performance evaluation of the smart device and proposed an evaluation environment for performance evaluation in mountainous area.

Because the thickness and depth of consolidation layer vary at every location, the consolidation settlement and time have to be evaluated spatially. Also, for a rational evaluation of the uncertainty of the spatial distribution of consolidation settlement and time, it is necessary to adopt a probabilistic method. In this study, mean and standard deviation of consolidation settlement and time of whole analysis region are evaluated by using the spatial distribution of consolidation layer which is estimated from ordinary kriging and statistics of soil properties. Using these results and probabilistic method, the area that needs adopting the prefabricated vertical drain as well as raising the ground level for balancing the final design ground level is determined. It is observed that such areas are influenced by the variability of soil properties. The design procedure and method presented in this paper can be used in the decision making process for a geotechnical engineering design.

The multipurpose auditoriums in schools are the center of local community and the places of their life-long education. The multipurpose auditoriums are to be open and made available for use by local public as far as it does not interfere with the education of the schools. However, most of them are not open to public on the pretext of management problems while demands of local communities for the opening of the facility is rising. The role of the multipurpose auditorium as the place of physical training and its maximum availability to local community have be taken into account of from its design stage. The location of the auditorium itself has to be close to the main entrance of the school for easy access, its facilities located in one common area, their management and maintenance scheme adopted appropriately but legally, and then security and safety measurement have to be devised. Also, more studies are necessary to propose detail regulations for local sports facilities and to develop their interrelationship and network, in connection with sophistication of school facilities and BTL system.

The purpose of this study is on comparing complementary forest of village between Korea and China. For this, Jinan of Korea and Qingzhou of China were selected through the pre-survey about the representative region of both country. The main research method was literature study, field study and interview with local residents. The comparative analysis between two regions was performed by frequency analysis of surveyed data. Which shows complementary forest of village in two regions has so much in common and also has many differences which is related with the local practical life. As a result, it was identified that the area and remained number, concentration degree of Jinan were greater than those of Cheongju. But it was identified that the linear form and location were similar in both regions. Through these identification, it is helpful to establish policy direction of both countries about the complementary forest.

The purpose of this research is to compare housing wealth effects of home-owning single income couples (SIC) and dual income couples (DIC) on their non-durable consumption and to assess the effects by location, age groups, housing structure type, debt-to-asset ratio and employment status. Using the Korean Labor and Income Panel Study (KLIPS) of 2014, this empirical study identified 1,198 SIC households and 1,044 DIC households, and employed multiple regression analysis. The main results reveal that the difference of financial portfolios between SIC and DIC households was little but housing wealth effects were stronger among SIC households than DIC counterpart. It's evident that housing wealth effects were conspicuous for SIC and DIC households who were headed by wage earners aged over 40s, and resided in apartment outside the Seoul Metropolitan Area. However, household debt became a determinant in contradicting housing wealth effects of SIC and DIC households. While the household financial dimension was in proportion to income, DIC households didn't gain much financial security due to increasing expenditure. Further, this research imply that liquidity constraints explicitly posed a more serious threat to SIC households whose dependence on housing asset is larger than their counterpart.

The kinematic and complicance characteristics of torsion beam axle is structurally related to the location and section profile of torsion beam and the span from body mounting point to wheel center. This paper presents the effect of section properties in torsion beam on the structural characteristics and roll behavior of suspension. The structural characteristics is on the maximum stress on the welding area of torsion beam and the roll behavior is on roll steer and roll-camber of suspension which are important for controllability and stability in cornering. Four factors are used for the section design of torsion beam, which are thickness , midline length, are inner radius, and sector half angle . Through the structural and quasi-static analysis made for six torsion beam axle models, it can be noticed that roll steer and the structural durability of suspension are closely related to warping constant and shear center in section properties of torsion beam.

It is essential to measure load transfer mechanism of pile to check the appropriateness of assumptions made for design purpose and to continuously monitor the behavior of pile foundation. Through many attempts to monitor the behavior of super-structure in civil engineering area using several optical fiber sensors have been made, application of optical fiber sensor technology on pile foundation has not been tried up to now. Load transfer of model piles during compression loading was measured by optical fiber sensors and compared with the measurement by strain gauges. Fiber Bragg Grating(FBG) sensor system was used since it has many advantages, such as easy multiplexing, high sensitivity, and simple fabrication. Besides the model pile tests, uniaxial tension test of steel bar and compression tests of mortar specimen were carried out to evaluate the performance of FBG sensors in embedded environments. The shift of refilming wavelength due to the strain in FBG sensor is converted to the strain at sensor location and the dependence between them is 1.28 pm/${\mu}$ strain. FBG sensors embedded in model pile showed a better survivability than strain gauges. Measured results of load transfer by both FBG sensors and strain gauges were similar, but FBG sensors showed a smoother trend than those by strain gauge. Based on the results of model pile test, it was concluded that the use of FBG sensor for strain measurement in pile has a great potential for the analysis of pile load transfer.
