Recently, the domestic remodeling market is increased in scale. This study is to develop the sanitary piping system which improves quality of life and facility performance when the aged public housing is remodeled. Above all, we found out three standard floor plans in bathrooms of the public housing. And then, the plan and section types of the sanitary piping system were developed for the on-floor piping, a construction cost of each section types was estimated to review the economical fact. Also, the field mock-up test was performed in the type of the pipe shaft with on-floor pit. In result, the developed sanitary piping system was available for the remodeling public housing without a great facility cost. Additionally, the sanitary pipe was replaced easily through the shaft and on-floor fit. And a noise was reduced to a lower unit when the water flowed down.

A common control model used to implement computer integrated manufacturing(CIM) is based on the hierarchical decomposition of the shop floor activities, in which supervisory controllers are responsible for all the interactions among subordinates. Although the hierarchical control philosophy provides for easy understanding of complex systems, an emerging manufacturing paradigm, agile manufacturing, requires a new control structure necessary to accommodate the rapid development of a shop floor controller. This is what is called autonomous agent-based heterarchical control. As computing resources and communication network on the shop floor become increasingly intelligent and powerful, the new control architecture is about to come true in a modern CIM system. In this paper, heterarchical control is adopted and investigated, in which a controller for a unit of device performs three main functions - planning, scheduling and execution. Attention is paid to the planning function and all the detailed planning activities for heterarchical shop floor control are identified. Interactions with other functions are also addressed. In general, planning determines tasks to be scheduled in the future. In other words, planning analyzes process plans and transforms process plans into detailed plans adequate for shop floor control. Planning is also responsible for updating a process plan and identifying/resolving replanning activities whether they come from scheduling or execution.

This study focuses on the fact that the Korean traditional design application appears as one of the trends for a planning technique to express an apartment as a healthy, clean and environment-friendly dwelling recently. Focusing on this, this study tries to apply the characteristic of Han-Ok to an apartment unit plan more compositively beyond the fragmentary design application of existing preceding researches. To do this, the space organization, residential space and housing design elements of Han-Ok are deducted through preceding researches and case studies and proposes a plan by applying this to the apartment plan with a floor plan of about $132m^2$(40 pyeong). The apartment unit plan containing the characteristic of Han-Ok proposed in this study is planned based on the floor plan of about $132m^2$(40 pyeong) which is distributed the most in the city of Seoul. It has an advantage in terms that it can be individually applied not only when a construction firm progresses business anew carrying the banner for a Korean-style apartment but also an existing residents can apply through remodelling. Meanwhile, it has a limit that the diversified space sense and the advantage of an airy Han-Ok cannot be applied to many parts of the design due to the characteristic of an apartment of diverse height change. If a measure to secure constructability and economic feasibility while reflecting diverse differences of floor-level of an apartment can be prepared in follow-up researches, much more various advantages of Han-Ok can be put into the apartment design.

The purpose of this study is to provide the method of saving the construction cost per unit area of the New Hanok using the inner space of a roof as a floor space with a structural modification of it's roof. The proportion of a roof of the Traditional Hanok accounts for about a half of it's elevation, so it is an essential element of it. But, compare to the whole construction cost of the Traditional Hanok, it costs over a half of expenses to build it. Recently, at the traditional building type, it is found that the inner space of a roof of it is used as a floor space with a structural modification of it's roof. It can be divided into two types, the storage type and the living type. The New Hanok at downtown can accommodate various new lifestyle, so the length of it's Yangtong is longer than that of the Traditional Hanok. When we adjust the proportion of the traditional Hanok to the New Hanok, the height of the column and the roof of the New Hanok becomes also higher than those of the traditional Hanok. So, using the upper part of the column and the roof of the New Hanok, we can make the inner space of a roof of the New Hanok as a floor space -like a bed room, tea room, personal work space and a storage- vertically connect with the 1st floor as the main living area. As a result, it is expected to save the unit construction cost of the New Hanok and has an extensity of space when we build the New Hanok at downtown.

In this paper, an Embedded solution for fast navigation and precise positioning of mobile robots by floor features is introduced. Most of navigation systems tend to require high-performance computing unit and high quality sensor data. They can produce high accuracy navigation systems but have limited application due to their high cost. The introduced navigation system is designed to be a low cost solution for a wide range of applications such as toys, mobile service robots and education. The key design idea of the system is a simple localization approach using line features of the floor and delayed localization strategy using topological map. It differs from typical navigation approaches which usually use Simultaneous Localization and Mapping (SLAM) technique with high latency localization. This navigation system is implemented on single board Raspberry Pi B+ computer which has 1.4 GHz processor and Redone mobile robot which has maximum speed of 1.1 m/s.

The demand for automatic manufacturing systems is increasing. One of the crucial obstacles to the Flexible Manufacturing System(FMS) is the lack of excellent strategies for efficient operations. The aim of this research is constructing an automaton scheme in the low level of factories where various machineries are involved. An operating strategy is established for an automation unit named as a cell which resides between the upper level computers and manufacturing shop floor. The cell is defined to fit into the total manufacturing system. The defined cell has more functions than conventional cells. A scheduling scheme is adopted for the shop floor operations. A set of software has been developed and tested through simulations and shop floor experiments.
