Non-territorial workplace has different characteristic from conventional workplace in terms of interior and architectural design and organization management even the user awareness. The purpose of this study is to examine the non-territorial workplace and suggest needs for improving the quality and efficiency of work. To fulfill this task, information describing various environmental conditions and user awareness were gathered from the non-territorial office in Seoul. Data were collected by using questionnaires regarding general information of user and satisfaction of environmental elements that were established on pre-study. Finally, based on the results of this study, the users of non-territorial workplace seem to be satisfied with utilization of space and working but discontent with psychological element such as privacy, security and affinity. Therefore designers should focused more on psychological elements according to users awareness which is the finding in this study among other elements.

For low-power sensor networks, a compact design of advanced encryption standard (AES) algorithm is needed. A very small AES core for ZigBee devices that accelerates computation in AES algorithms is proposed in this paper. The proposed AES core requires only one S-Box, which plays a major role in the optimization. It consumes less power than other block-wide and folded architectures because it uses fewer logic gates. The results show that the proposed design significantly decreases power dissipation; however, the resulting increased clock cycles for 128-bit block data processing are reasonable for IEEE 802.15.4 standard throughputs.

Reasonable disaster prevention signs play an important role in guiding evacuation. Through the field investigation on disaster prevention signs in shelters and surrounding areas in Beijing, some problems were found in the using of sign system. Based on the principle of integrated design, evacuation and rescue requirements, it is necesssary to make further study on aspects such as, design of function, systematic consideration, humanization design, as well as the internationalization using. This paper presents an evaluation index system for disaster prevention signs. Such a system is very important for strengthening the independent guiding function of sign systems and improving evacuation efficiency. An effective connection could be realized between the internal environment of buildings, evacuation routes, and emergencey shelters.

In this paper, we propose a hybrid cooperative scheme to improve the secrecy rate for a cooperative network in presence of multiple relays. Each relay node transmits the mixed signal consisting of weighted source signal and intentional noise. The problem of power allocation, the joint design of beamforming and jamming weights are investigated, and an iterative scheme is proposed. It is demonstrated by the numerical results that the proposed hybrid scheme further improves secrecy rate, as compared to traditional cooperative schemes.

As car seat is the closest part between driver and rider, the interest of the security and comfort of the seat is increasing. This research discovered the best condition for dyeing and finishing to produce a fabric for car seat and also developed the design of fabrication to give the feeling from such a finishing. The best condition of coating finishing solution is aqueous PU 65%, dye resist reagent 20%, water 12%, thicker 3%, and knife thickness 2mm, tenter temperature $170^{\circ}C$, tenter speed 35yard/min, viscosity 12,000cps and stirring time 100kg * 30min. According to the processing time of knife coating upon stirring the change of resin and the uneven of coating quantity was shown. This problems will be solved by means of automatic temperature control apparatus for resin and sealing device through a coming research.

In general, weapon system design/configuration data consist of system structure information which is linked to Part information, documents and drawings. For configuration management, version and revision control are necessary and access control of users to information should be managed for information security. Configuration data of weapon systems have various kinds of different meta data which are contained in the structure as well as attributes of parts and documents information. If neutral types of meta data models be used for building configuration management system, they can be applied to many different kinds of weapon systems with a little customization. In this paper, five meta data models are supposed and implementation results of them by using CBD(component based design) methodology are presented.

The focus of this study was on spatial and interior characterization of recently developed and marketed apartments. The house showrooms in the Seoul Metropolitan Areas that have recently been open were selected and analyzed. The floor plans and relevant materials via website for each showroom provided by major housing development companies were examined, and site visits were made. The finding of this study indicated that high-tech systems were applied to heighten security and safety. It was revealed that various exterior design features were adopted and emphasized, so they affected spatial composition and utilization. Another finding was the use of environmentally friendly materials and features as indoor air quality became an emerging concern. Additionally, it was noticed that features in relation to open housing and interior finishes became more customized to meet different needs of consumers. Therefore, the characteristics of recent house showrooms were summarized into high-tech, environmental friendliness, and customization.

This paper presents a design of network and database structure of the integrated system for power system operational planning and analysis that will be more economical and stable of power system operation. An alias of this system is Highly Integrated Total Energy System(HITES). The Client/server model of HITES is designed as a remote data management model. The input/output-type of application programs and Oracle server is standardized. The separated user-databases from main-database strengthen security of HITES. It is plan to do that tables and relationships are defined by database designs. The connection of application program and DBMS of HITES will be tested through database design and data construction.

Recently, the number of Internet shopping malls increases dramatically Internet shopping malls offer direct sales by electronic catalogs. As compared with to physical stores and paper catalogs, electronic catalogs differ in terms of the varieties and types of products offered, promotional efforts, service, interface, ordering and delivering, and so on. This paper analysed the features of electronic catalogs for fisheries by 45 variables. By descriptive statistics of electronic catalogs for fisheries, most electron)c catalogs had sufficient product related information. But promotion and transaction security related features were scarce. And some development technologies of electronic catalogs for fisheries were obsolete. By factor analysis, there were 9 factors of electronic catalogs for fisheries, that was, design of product pages, transaction information, playfulness, convenience of product selection, interface design, design of homepages, product information, learning capability, other electronic catalog related factor. Thus in standardizing electronic catalog for fisheries products, the above 9 factors should be reflected significantly.
