The latest trend of our medical industry seems to have a raise on more expectation and interest in mystical therapeutics of herb medicine and its efficiency especially for the disease such as chronicity and other obstinacy that used to be impossibie to be cured with only Western medical treatment. potentiality of ideal medical treatment through interchanging of medical study between Eastern and Western is becoming an issue today. Herb medicine is our native ethnic medicine and is based on the friendly-nature and human oriented under one of the classification of natural medicine. The point of this medicine has a strong connection with the conceptional trait of Health-Care that is been newly paid a lot of attention in Western medical science. This 'Y'Oriental Medical Clinic Interior Design is to grant a new possibility of global recognition of herb medicine getting over from a limited ethnic medicine by correcting the existing problems and expanding its scope to a part of natural medicine and to newly establish its meaning as a space for Health-Care utilizing a concept of nature.

The all revision of the Road Name Address Act, which contains the contents to be used by expanding the road name address as a means of indicationg the location, has been resloved by the National Assembly. Addresses will be assigned to large-sized facilities (3D mixed-use complex spaces). Here, the 3D (Three-dimensional) address is assigned an indoor path section in the inner passage, dividing the section at intervals. The 3D address will be built on the address information map. For 3D address, data should be built and managed for a 3D complex space(indoor space). Therefore, in this study, the object of the 3D address is defined based on the address conceptual model defined in the international standard, and the 3D address data model is proposed based on IndoorGML. To this, it is proposed as a method of mapping the Core and Navigation module of IndoorGML so that the entity of the 3D address can be expressed in IndoorGML. This study has a limitation in designing a 3D address data model only, but it is meaningful that it suggested a standard for constructing 3D address data in the future.

무인 운반차(AGV, Automated Guided Vehicle)은 1955년에 개발된 자재 운반용 무인운송 시스템으로 초기에는 제조 현장에서 자재의 운송에 국한되어 사용되었다. 최근에는 창고, 컨테이너 터미널 그리고 지하공간에서의 반복되는 실내/외 운송으로까지 그 사용이 확산되고 있다. AGV는 제조현장에서 제조 공정과 관련된 모든 자재의 이송에 적용되고 반복되는 운송의 형태에 사용되며, 실내 용도로는 수입, 저장, 분류, 반출, 이송과 공정 간의 파레트(Pallet) 이송에 사용되며, 비교적 작은 용량의 AGV가 이러한 제조현장에서 산업용도에 쓰이고 있다. AGV는 실내에서 주로 사용되는 환경적 특성상 배터리를 사용하며, 충전하거나 교환하여야 하며, 이에 소요되는 시간이 시스템의 성능에 큰 영향을 미친다. 대부분의 제조현장이나 배송센터에서 AGV는 비교적 짧은 거리를 운행하므로 대기 시간 중에 배터리를 충전하거나 교환이 가능하다. 하지만 비교적 장거리를 운행하는 시스템에서는 AGV의 가동률을 50% 이하로 유지하거나 온라인 충전 시스템을 구비하여야만 배터리 전압 강하에 의한 시스템의 마비를 예방할 수 있다.

The multi robot operation technique has emerged as one of the most important research subjects that focus on minimizing redundancy in space exploration and maximizing the efficiency of operation. For an efficient operation of the multi robot systems, the movement of each Single robot in the multi robot systems should be properly observed and controlled. This paper suggests Multi Robot Management System to minimize redundancy in space exploration by assigning exploration space to each robot efficiently to take advantage of the RFID. Also, this paper has suggested fault tolerance technique that detects disable Single robot and substitute it by activated Single robot in order to ensure overall exploration and improve efficiency of exploration. Proposed system overcomes previous fault that it is difficult for central server to detect exact position of robot by using RFID system and Home Robot. Designated Home robot manages each Single robot efficiently and assigns the best suited space to Single robot by using RFID Tag Information. Proposed multi robot management system uses RFID for space assignment, Localization and Mapping efficiently and not only maximizes the efficiency of operation, but also ensures reliability by supporting fault-tolerance, compared with Single robot system. Also, through simulation, this paper proves efficiency of spending time and redundancy rates between multi robot management applied by proposed system and not applied by proposed system.

Recently, prior to the commercialization of urban air mobility (UAM), the importance of R&D for air transportation-related industries in urban areas has significantly increased. To create a UAM environment, research is being conducted on personal air vehicles (PAVs). They are key means of air transportation, but research on the physical factors influencing their passengers is relatively insufficient. In particular, because the PAV is expected to be used as a living space for the passengers, research on the effects of the physical elements generated in the PAV on the human body is essential to design an interior space that supports the in-vehicle activities of the passengers. Therefore, the purpose of this study is to derive the constraint factors that affect the human body due to the air navigation characteristics of the PAV and to understand the impact of these constraint factors on the bodies of the passengers performing in-vehicle activities. The results of this study indicate that when the PAV was operated at less than 4,000 ft, which is the operating standard, the constraint factors were noise, vibration, and motion sickness caused by low-frequency motion. These constraint factors affect in-vehicle activity; thus, the in-vehicle activities that can be performed in a PAV were derived using autonomous cars, airplanes, and PAV concept cases. Furthermore, considering the impact of the constraint factors and their levels on the human body, recommended constraint factor criteria to support in-vehicle activities were established. To reduce the level of impact of the constraint factors on the human body and to support in-vehicle activity, the seat's shape and built-in functions of the seat (vibration reduction function, temperature control, LED lighting, etc.) and external noise reduction using a directional speaker for each individual seat were recommended. Moreover, it was suggested that interior materials for noise and vibration reduction should be used in the design of the interior space. The contributions of this study are the determination of the constraint factors affecting the in-vehicle PAV activity and the confirmation of the level of impact of the factors on the human body; in the future, these findings can be used as basic data for suitable PAV interior design.

IoT (Internet of Things) technologies have largely contributed to our smart living environment. The smart parking system is one of the prominent services that IoT supports. To identify the parked vehicles, the previous parking system use special identifying devices, the RFID tags carried by the users, and the high quality camera to recognize the vehicle license numbers. However, the previous methods cause cost inefficiency and unfriendly usages. To address these problems, we propose a smart parking system based on ultrasonic sensors and Bluetooth communication. The proposed system decides the available slots by using the sensor motes located in the parking spaces. Also it recognizes the location of the parked vehicle using Bluetooth RSSI between a Smartphone and the sensor motes. In addition, based on these converging technologies, it can support the parked routes of vehicles for users. To evaluate the implemented smart parking system, we applied the RSSI transform equations and the recognition rate for parked vehicles. As a result, the accurate rate of transformed distances could be measured.

It is necessary to produce and maintain interior lighting design reasonably and actively. Based on the lighting design applicable to interior design, the purpose of this study is to take into consideration the public design of public facilities installed in neighborhood parks and thereby to suggest a module-type variable interior lighting product design for reasonable use. To achieve that, relevant studies were reviewed to find the basic concepts of a module and the best cases of interior lighting applicable to interior design. To draw a new concept of the lighting design to which the concept of a module is applied, this study suggested the design direction for practical product development and a module-type design featuring easy process, product storage, assembly, and management, analyzed the reasonable maintenance direction for the development of lighting design, and proposed a case of design development applicable to the development of a new product design. Through cognitive strategy process, the design was made. This process, as a conceptual strategy, included the step of interior environment analysis, the step of lighting maintenance, the step of variable mechanism, and the step of emotional activation. These steps were connected with formative beauty of design so as to suggest a MLD(Module Lamp Design) strategy. In this way, this study tried to connect humans' free application for a space to a module product and to apply humans' visual approach and free conceptual value to MLD cognitive strategy design process for development.
