University campus has grown and developed along with history of human in connection with transition characteristics of city. In particular, reflecting the features in the times, the masterplan should explore its main roles today when international growth of university is pursued. In particular, center core and quad space, focusing on main components of campus such as main building, student union hall and main lecture facility, are the prototype of campus components and have been pursued to have importance in terms of shape and function as traditional campus space strategy. Recently, however, new strategy has been proposed to explore orders of campus utilizing the underground space focusing on main universities. Design of Hana Plaza of Korea University and Bekyangro of Yeonsei University, the targets of this study, actively explore this strategy. This study analyzed such strategies in terms of concept of space to obtain space, design trend of main universities at home and abroad, and viewpoint of integrated masterplan proposal. Conclusions from this study are as follows. First, concept of quad and center space found in the design of traditional campus is reinterpreted into new design aspects through development of underground space. Second, development of underground space is approached to overcome the limit of existing campus and to present the vision of universities 100 years ahead. Third, ever-changing complicated urban environment has been reflected in space configuration of campus and positioned as strategy to implement this as modern construction technique. Third, implementation of pedestrian-oriented campus has been pursued by reinforcing utilization of inclined topography of urban environment in Korea. This enables to obtain spaces for main activities of students and to implement the space where student support facilities are concentrated and activities are performed actively. Such features can be presented as conclusions of this study.

In this paper, a brief but essential development strategy for the lunar orbit determination system is discussed to prepare for the future Korea's lunar missions. Prior to the discussion of this preliminary development strategy, technical models of foreign agencies for the lunar orbit determination system, tracking networks to measure the orbit, and collaborative efforts to verify system performance are reviewed in detail with a short summary of their lunar mission history. Covered foreign agencies are European Space Agency, Japan Aerospace Exploration Agency, Indian Space Research Organization and China National Space Administration. Based on the lessons from their experiences, the preliminary development strategy for Korea's future lunar orbit determination system is discussed with regard to the core technical issues of dynamic modeling, numerical integration, measurement modeling, estimation method, measurement system as well as appropriate data formatting for the interoperability among foreign agencies. Although only the preliminary development strategy has been discussed through this work, the proposed strategy will aid the Korean astronautical society while on the development phase of the future Korea's own lunar orbit determination system. Also, it is expected that further detailed system requirements or technical development strategies could be designed or established based on the current discussions.

There are generally three folds when developing neural network classifiers. They are as follows: 1) discriminant function; 2) lots of parameters in the design of classifier; and 3) high dimensional training data. Along with this viewpoint, we propose space search optimized polynomial neural network classifier (PNNC) with the aid of data preprocessing technique and simultaneous tuning strategy, which is a balance optimization strategy used in the design of PNNC when running space search optimization. Unlike the conventional probabilistic neural network classifier, the proposed neural network classifier adopts two type of polynomials for developing discriminant functions. The overall optimization of PNNC is realized with the aid of so-called structure optimization and parameter optimization with the use of simultaneous tuning strategy. Space search optimization algorithm is considered as a optimize vehicle to help the implement both structure and parameter optimization in the construction of PNNC. Furthermore, principal component analysis and linear discriminate analysis are selected as the data preprocessing techniques for PNNC. Experimental results show that the proposed neural network classifier obtains better performance in comparison with some other well-known classifiers in terms of accuracy classification rate.

Recently the coffee industries rapidly grow as people's dietary life changes and quality of life improves. Proliferation of coffeehouses let people cognize them as cultural spaces not only mere spaces for drinking coffee beverages. Therefore, distinguished strategy for space design became the one of the most important factor for customers' decision-making. This study analysed the strategies for space design by the brands of coffeehouses, and focused on understanding how those strategies cognized by customers and how they affect customers' level of satisfaction and intention of revisitation. The result of analysis showed that the level of satisfaction was raised when customers cognized unique strategies by brands and the intention of revisitation was raised when the level of satisfaction and reflection of strategy were high. In other words, setting and applying unique strategies by brands are to raise up level of satisfaction and intention of revisitation. The result of study could be used for the basic data on designing coffeehouses attracting customers' revisitation. Also, it could be the basis for effective strategy for customers.

With the development of the NB-IoT (Narrow band Internet of Things) and smart cities, coupled with the emergence of smart smoke sensors, new requirements and issues have been introduced to study on the deployment of sensors in large spaces. Previous research mainly focuses on the optimization of wireless sensors in some monitoring environments, including three-dimensional terrain or underwater space. There are relatively few studies on the optimization deployment problem of smart smoke sensors, and leaving large spaces with obstacles such as libraries out of consideration. This paper mainly studies the deployment issue of smart smoke sensors in large spaces by considering the fire probability of fire areas and the obstacles in a monitoring area. To cope with the problems of coverage blind areas and coverage redundancy when sensors are deployed randomly in large spaces, we proposed an optimized deployment strategy of smart smoke sensors based on the PSO (Particle Swarm Optimization) algorithm. The deployment problem is transformed into a multi-objective optimization problem with many constraints of fire probability and barriers, while minimizing the deployment cost and maximizing the coverage accuracy. In this regard, we describe the structure model in large space and a coverage model firstly, then a mathematical model containing two objective functions is established. Finally, a deployment strategy based on PSO algorithm is designed, and the performance of the deployment strategy is verified by a number of simulation experiments. The obtained experimental and numerical results demonstrates that our proposed strategy can obtain better performance than uniform deployment strategies in terms of all the objectives concerned, further demonstrates the effectiveness of our strategy. Additionally, the strategy we proposed also provides theoretical guidance and a practical basis for fire emergency management and other departments to better deploy smart smoke sensors in a large space.

Brand is a useful tool for modem people living under the age of the brand, to explain the information of their products by differentiating themselves from others. It also represents the value of company and plays a major role convincing customers. Even living space brands are no exception. According to the development of marketing management ability, living space brands require the new sales strategy to dominate the market over the business competition, and plan differently for a changing market environment. On such account, companies are commercializing the living space via establishing its brands. Thus the study will cover the living space differentiation strategies for promoting the brand images of respective construction companies and will strive to compare and analyze the differentiation strategy factors that construction firms are pursuing through case analysis framework. Moreover, it's objective focuses on materializing the strategies of living space in accordance to the brand application elements.

This study, by applying the experiential and psychological thought category of "impression" as the space design strategy for drawing out "sensitivity," aims to break down the psychological mechanism forming the image held by the subject, and based on such segmentation, seek and strategize an effective design methodology. The subject's memory, pure sensation, and movement sensation are set as the preceding determinants comprising the psychological mechanism of space impression. The control determinants for achieving activation of psychological effect are reinterpreted as the relations of memory-cognition, sensation-perception, and movement-sensation and categorized into a cognitive strategy based on association, metaphor and remembrance; a direct sensation strategy based on formation, superposition and transposition of sensation; and a sensation strategy of process-formation based on expectation organization and reversal, contraction and relaxation. Each strategy is achieved through the formal, material and structural control of architecture. As a restructuring of the design methodology that has been experientially applied, the strategy categorization is important in that, by presenting the usefulness and effect by strategy according to space experience, it makes concrete the basic data that are useful for designing experience of sensitivity.
