In the work package 'Integrated Positioning' of the research project NAVIO (Pedestrian Navigation Systems in Combined Indoor/Outdoor Environements) we are dealing with the navigation and guidance of visitors of our University. Thereby start points are public transport stops in the surroundings of the Vienna University of Technology and the user of the system should be guided to certain office rooms or persons. For the position determination of the user different location sensors are employed, i.e., for outdoor positioning GPS and dead reckoning sensors such as a digital compass and gyro for heading determination and accelerometers for the determination of the travelled distance as well as a barometric pressure sensor for altitude determination and for indoor areas location determination using WiFi fingerprinting. All sensors and positioning methods are combined and integrated using a Kalman filter approach. Then an optimal estimate of the current location of the user is obtained using the filter. To perform an adequate weighting of the sensors in the stochastic filter model, the sensor characteristics and their performance was investigated in several tests. The tests were performed in different environments either with free satellite visibility or in urban canyons as well as inside of buildings. The tests have shown that it is possible to determine the user's location continuously with the required precision and that the selected sensors provide a good performance and high reliability. Selected tests results and our approach will be presented in the paper.

This project is to establish an annex clinic center under 5 floors with gross floor area of 3,000 Pyeong behind existing Chosun university Hospital main building with 600 beds. The goal of the design is connecting the new clinic center with the existing main building and completing a combined hospital that has synergy effects. Given the old condition of the hospital and characteristics of the ground, I tried to embody the image of Medical Pulse, which is very alive with strong pulse, and suggest vision of 21st century hospital. First, one main entrance as a combined hospital. For optimum access and functions, I used the entrance of existing building as the only main entrance of new combined hospital, rearrange the road in front of the main building and improve traffic system, and upgrade the image and function of combined main entrance by planning new atrium united robby that makes link to the main building easier. Second, section planning considering the optimum functions and convenience. I established 4 floors linking functionally with the existing building, minimized vertical traffic line, and enhanced convenience through barrier free environment, which is a horizontal traffic line without barriers, crucial to hospital. Third, combined zoning generating synergy effects. I linked sterilizing room with logistics center by operating room and service bridge, and arranged central treatment department horizontally, Also, by horizontally arranging cancer center and department of nuclear medicine close with PET and cyclotron center, I established identity of specialized departments.

Although the weapon systems are becoming more diverse and complex, they are progressing in a short development period and a longer test and evaluation period. The more difficult the given environment is, the more efforts and performance of quantitative target values can be made by development agencies to carry out stable projects. However, these target values of the Integrated Logistics Support are not specified in the requirements and being set during the system development phase. In this paper, application of MOEs, MOPs and TPMs for ILS are presented and provided the basis for carrying out systematic Verification & Validation activities. As a result that MOEs of the ILS were chosen as Availability and MOPs as Mission Reliability, Logistics Reliability, Maintainability and Supportability and TPMs as MTBF, MTBCF, MTTR and so on. In particular, it is appropriate tailoring and apply the TPMs considering the cost, schedule, scope of work and characteristics of the project.

The residential and welfare facilities for the elderly are continuously increasing due to change of value on family under situation of aging population increase. And it is predicted that accommodation capacity of facilities for the elderly and its rate those facilities takes compared to whole social welfare facilities will be accelerated considering past increase speed. On the other hand, about 60% of the elderly have low physical and mental level almost close to disabled people therefore special environmental concerns helping their independent living are necessary. Among them, color application is one of the most important factors for smooth understanding, communication and psychological remedy effect for them. The purpose of this study is to analyze the interior color status in assisted living facilities for the elderly in America which is a leading country in terms of the understanding and policy for the elderly as a part of the research project to suggest the developed solution about the Korean residential welfare facilities for the elderly For this purpose, not only importance and effect of color and visual characteristics and reaction to color in elderly environment but also general concept and policy of the ‘assisted living facility’ in America were researched through documents review. And measuring of color on 5 main spaces such ; lobby/lounge, corridor, dining room, bedroom, stairway/ramp of the 10 facilities in America were performed under analysis of its functional and aesthetic level based on Moon & Spencer's color theory.

This study focused on diagnosing and analyzing the level of sustainable development for each fishing communities by applying the sustainable development index in the fishing communities to support the policy of revitalizing the fishing communities. In terms of methodology, diagnostic indicators for rural areas were used through previous studies and literature surveys, and three categories, five fields and 27 indicators were finally selected through collecting opinions from experts. After deriving the weight for each indicator in detail, the final sustainable development index of the fishing communities was applied to fishing village fraternity. Based on the results of the analysis of the application of sustainable development cases in fishing communities, policy support should be implemented differentially according to regional decline factors and potential growth factors. In the population and social sector, it is necessary to consider ways to reduce population and reduce aging. In the industrial and economic sectors, fishing activation and systematic support for fishing-related industries should be provided. In the marine and built environment sector, the government's active project execution and budget support are required. In addition, it is expected to be used in various ways in the process of developing fishing communities and establishing revitalization plans that reflect the characteristics of the region.

The purpose of this study was to survey Navajo's textiles of the transitional period(1868-1890) and to examine appearance background of those textiles. The two study questions were central to the project. 1) What were characteristics of eye-dazzler and pictorial in the transitional period? 2) How developed was the American trader's role? To perform the purpose, literatures on this subject were surveyed, investigation of textiles in Arizona State Museum and Historical Museum of Arizona were accomplished. The results of this study were as follows: 1. Eye-dazzler is called because of their small, serrate triangle and diamond patterns in intense, contrasting colors. Eye-dazzler mostly used Germantown yam and wedge-weave technique. Germantown was a plied yam colored with synthetic dyes. Wedge-weave technique used optical illusions and an undulating technique to create an effect of motion and rhythmic symmetry. 2. The Americans began to intern Navajos at Bosque Redondo, New Mexico in 1863. During their stay at Bosque Redondo, the Navajo came into greater contact with Rio Grande blankets. The influence of designs of these becomes increasingly important in the eye-dazzler. 3. Pictorial materials included rich new sources the railroad provided and living environment of animals, plants, hogans, neighbors, deities that interested the Navajo. Also, sandpainting textiles were a pictorial. Three types of textiles utilized: yei, yeibichai, and sandpainting tapestry. 4. The arrival of the railroad caused many changes for the lives and textiles of the Navajos. The railroad brought a new client into the Navajo, and the Navajos attempted new textiles with design-inspiring fresh materials to adjust taste of the eastern purchasers.

Purpose: The construction of New Han-ok style public buildings is a construction that can not be seen in traditional Han-ok, and it is a construction that combines traditional wooden structure, RC structure, and steel structure. Therefore, construction different from general construction is complicated and complex. It is necessary to accurately understand the construction method of each field rather than the general construction management method and study the method suitable for New Han-ok style public buildings. Also, since the New Han-ok style public building business is the first business to be introduced in Korea, new process management is needed rather than general process management. Method: The research method is as follows. Analyze process management through theoretical considerations and analyze the differences from general construction projects. Next, we want to identify the characteristics and problems of the process control method applied to real cases. Finally, the results of this analysis suggest ways to improve process management. Result: Therefore, it is necessary to establish a precise plan from the basic design to the construction of the public building construction management. In addition, careful planning should be made so that the supply and demand of materials and the supply and demand of personnel can be achieved smoothly.

As component-based development (CBD) rapidly spread throughout the software industry, a comprehensive methodology is needed to apply it more systematically. For this purpose, a new CBD methodology named Magic & Robust Methodology Integrated III (MaRMI-III) has been developed. The purpose of this paper is to present MaRMI-III by its constituent processes and claim that it can be used to support system developers conduct CBD in a consistent manner. First, we review the CBD approach to system development and the role of CBD methodology, and then we explain the several characteristics of MaRMI-III which are considered necessary to the CBD environment. Next, we explain a process model of MaRMI-III which separates the development process from the project management process and prescribes well-ordered activities and tasks that the developer should conduct. Each phase forming the Process Model is explained in terms of its objectives and main constituent activities. Some techniques and workproducts related to each phase are also explained. Finally, to examine the usefulness of MaRMI-III, an analytical comparison with other CBD methodologies and the results of a questionnaire survey are described.

Travel distance is a parameter mainly used in the objective function of Construction Site Layout Planning (CSLP) automation models. To obtain travel distance, common approaches, such as linear distance, shortest-distance algorithm, visibility graph, and access road path, concentrate only on identifying the shortest path. However, humans do not necessarily follow one shortest path but can choose a safer and more comfortable path according to their situation within a reasonable range. Thus, paths generated by these approaches may be different from the actual paths of the workers, which may cause a decrease in the reliability of the optimized construction site layout. To solve this problem, this paper adopts reinforcement learning (RL) inspired by various concepts of cognitive science and behavioral psychology to generate a realistic path that mimics the decision-making and behavioral processes of wayfinding of workers on the construction site. To do so, in this paper, the collection of human wayfinding tendencies and the characteristics of the walking environment of construction sites are investigated and the importance of taking these into account in simulating the actual path of workers is emphasized. Furthermore, a simulation developed by mapping the identified tendencies to the reward design shows that the RL agent behaves like a real construction worker. Based on the research findings, some opportunities and challenges were proposed. This study contributes to simulating the potential path of workers based on deep RL, which can be utilized to calculate the travel distance of CSLP automation models, contributing to providing more reliable solutions.

This project aims to provide information on organizations and characteristics of Korean designer fashion industry in order to improve employment environment in fashion designer brands. This study utilizes the questionnaires and interviews with designers or human resources managers in Korean designer brands for forms, size and way of employment. The result shows that firstly, the size of employment in fashion designer brands is almost operated by small-scale human resources. Secondly, It is researched that they recruit less than 10 temporary employees per a brand on average as a problem. Thirdly, there are differences in business according to forms of employment. As researched, permanent employees usually conduct in design, products plan and production management, but, temporary employees conduct as a business assistant and salespeople. Fourthly, it is revealed that average salaries for permanents in fashion designer brands are between 1,510,000 and 2,000,000 won as the most people said. Moreover, the average salaries for temporaries are similar with permanents' as between 1,170,000 and 1,500,000 won. In fifth, in terms of the ways for recruitment, the proportion of job seekers who find a job by nonscheduled admission and special employment is larger than other ways. Finally, as a result of a research on an employment contract, employees have written the employment contract with the brands.
