The purpose of this study is to suggest a strategy of introduction of Larchiveum, which is a concept of multi cultural space in libraries. Problem of library space programs are discussed in terms of Larchiveum and Maker space, and recently it has been studied in various aspects such as Europeana, GLAM and DPLA from the view point of digital Larchiveum. As a multi cultural space, it is a strategy for constructing Larchiveum that reflects the recent maker's movement. Maker space that explores new ideas and encourages active participation of users, nature and health, curiosity and the construction of an attractive space using ecological concepts as key words. The processes and methods for constructing Larchiveum are classified into 3 types of space configuration, service, program, and operating regulation, and twelve details are laid out to derive the process and method of building Larchiveum as a future type library.

Smart phone allows advertisers to estimate customers behavior by selecting user context awareness information and gives users instant feed back about their behavior. Electronic equipments such as smart phone enable advertisers to advertise interesting product for each customers at the point of purchase. In this paper, we deal with the trends of Smart phone and internet based TV in the spotlight as the upcoming advertising media and propose the effective way of advertising, Smart Advertising model, which can give users advertising contents of their interesting product by collecting user context information from a variety of devices including N-screen in smart space. This model will induce modern people who live in flood of advertisements to buy products by providing interesting advertising contents.

As a result of analyzing the relationship between the smart growth principle and the regenerating factors of the port waterfront city, it was found to be highly related to the port waterfront regeneration plan. Factors that are related to the application of smart growth principle derived from association analysis are as follows: ⯈ community development suitable for walking ⯈ differentiated and attractive community building with definite place, ⯈ open space, farmland, beautiful natural scenery, environmental preservation, ⯈ strengthening and inducing development for existing communities, and providing diversity of transportation options. However, in the Jeju port redevelopment plan, the principles such as ⯈ complex land use ⯈ advantage of high-density architectural design method, ⯈ various housing opportunities and options, etc., need to be applied in implementation design. Since Jeju city and Jeju port possess the strong characteristic features of port waterfront city, so it is necessary to develop jointly applying smart growth principle through integrated port waterfront city regeneration plan.

Recently, as the importance of forced indoor living has increased in the untact era, the connection and relationship between space environments is increasing. That is, the smart interaction environment for providing services in various spaces collects and processes a number of surrounding environment information through various sensors to provide desired information according to the required place and time. In this environment, a new type of interaction paradigm is needed for the user to select and focus on environmental information. In this paper, we provide guidelines based on models and patterns for designing various interactions around space. Through interaction model-based technology, we provide guidelines for space-oriented interaction design. We propose an ideal interaction environment through guideline-based patterns and templates. Finally, by providing a space-oriented interaction environment suitable for smart interaction, users can freely obtain desired information.

In this paper, an Automatic Terrain Following (ATF) Simulator using Digital Terrain Elevation Data (DTED) was proposed. This ATF Simulator consists of a Flight Simulator, a Radar Simulator, and a Terrain Following Computer (TFC) Simulator. DTED and radar scan data generated with DTED were used as the terrain information necessary for terrain following. The ATF Simulator provides three modes of operation: a passive mode that uses DTED, an active mode that uses radar scan data, and a hybrid mode that uses both. We developed an ATF Simulator that could reduce the cost and time required to develop a terrain following system using the LabVIEW development environment and the MATLAB App Designer development environment. It was verified by confirming that the ATF Simulator met all functional requirements.

This paper studies an automation problem of a heating, a ventilating, and an air conditioning (HVAC) for the development of smart space. The HVAC system is described by the fuzzy system for the stability analysis and the controller design. The linear matrix inequalities (LMIs) conditions are derived for the stabilization problem of the closed-loop system under the analog control. Also, it is required to digitally redesign the pre-designed the analog HVAC control system in order to accomplish the remote control via web. It is shown the this digital redesign problem can be converted to the convex optimization problem with the LMI constraints. An example is provided to show the effectiveness of the proposed method.

In this paper, we propose the location measurement algorithm of unknown tag based on RFID (Radio-Frequency IDentification) by using RSSI (Received Signal Strength Indication) and TDOA (Time Difference of Arrival) and extended Kalman filter in smart space. To do this, first, we recognize the location of unknown tag by using the RSSI and TDOA recognition methods. Second, we set the coordinate of the tag location measured by using trilateration and SX algorithm. But the tag location data measured by this method are included complex environmental error. So, we use the extended Kalman filter in order to revise error data of the tag location. Finally, we validate the applicability of the proposed method though the simulation in a complex environment.
