Conventional Augmented Reality has used data gloves or markers for smooth interaction between objects and background. This causes inconvenience of use and lower immersion. To build up immersion in Augmented Reality, additional input devices must be removed. For this purpose, accurate recognition of space coordinates is needed even with no attachment of markers. This paper proposes a method to create virtual space coordinates for interaction without wearing additional input devices so as to improve immersion in Augmented Reality. The acquired image was projected to 2D space and vanishing lines were extracted to calculate the virtual space coordinates. Then the sizes of the inserted objects were varied in accordance with the size of the virtual coordinates area based on the image projected onto the 2D coordinates. This resulted in improved immersion. This method can increase the efficiency of object creation by excluding the use of a 3D modeler for creation of 3D objects.

As cities continue to expand and additional underground structures are constructed, a policy is being planned to expand addresses, which are national framework data. In this study, the application scope of a proposed 3D (three-dimensional) mixed-use complex space for assigning 3D addresses was defined, based on past research on 3D address systems and by analyzing related laws. Underpass shopping malls, underground walkways (excluding underground shopping malls), and 3D mixed-use transfer centers with a gross floor area of 2,000㎡ or more are connected with each space by underground walkways or public paths. In addition, the detailed space corresponding to the public space of the 3D mixed-use complex space was presented and distinguished from the space to which the detailed address is assigned. The criteria for setting the road section were presented based on the intermediate space, which is a characteristic of 3D mixed-use complex spaces. The proposed criteria were applied to the Express Bus Terminal station (3D mixed-use transfer center) and COEX mall (underpass shopping malls). Thus, the road section was set for an unfamiliar 3D mixed-use complex space. However, by applying the proposed criteria to various 3D mixed-use complex spaces, additional and detailed criteria for different cases should be prepared.

This study examined whether specific coping strategies for the university entrance examination stress are related to high school seniors' depression and whether these strategies moderate the relationship between additional life event stress and depression. A sample of 358 high school seniors reported their level of additional life event stress, coping strategies they were using to handle examination stress, and their levels of depression. Problem-focused coping strategies and affective-regulation coping strategies were found to be related to reduction in depression. And, coping with examination stress was found to be related to depression independent of the level of additional life event stress.

In this paper, an additional degree of freedom in phased multi-input multi-output (phased-MIMO) radar with any arbitrary desired covariance matrix is proposed using space-time codes. By using the proposed method, any desired transmit covariance matrix in MIMO radar (phased-MIMO radars) can be realized by employing fully correlated base waveforms such as phased-array radars and simply extending them to different time slots with predesigned phases and amplitudes. In the proposed method, the transmit covariance matrix depends on the base waveform and space-time codes. For simplicity, a base waveform can be selected arbitrarily (ie, all base waveforms can be fully correlated, similar to phased-array radars). Therefore, any desired covariance matrix can be achieved by using a very simple phased-array structure and space-time code in the transmitter. The main advantage of the proposed scheme is that it does not require diverse uncorrelated waveforms. This considerably reduces transmitter hardware and software complexity and cost. One the receiver side, multiple signals can be analyzed jointly in the time and space domains to improve the signal-to-interference-plus-noise ratio.

The absorbing material is mostly used to changing the acoustic energy to the heat energy in the passive control, and that consists of the porous media. That controls an air borne noise while the stiffened plates, damping material and additional mass control a structure borne noise. The additional mass can decrease the sound by mass effect and shift of natural frequency, and damping material can decrease the sound by damping effect. The passive acoustic control using these kinds of control materials has an advantage that is possible to control the acoustic in the wide frequency band and the whole space at a price as compared with the active control using the various electronic circuit and actuator. But the space efficiency decreased and the control ability isn't up to the active control. So it is necessary to maximize the control ability in the specific frequency to raise the capacity of passive control minimizing the diminution of space efficiency such an active control. Therefore, the characteristics of control materials and the optimum layout of control materials that attached to the boundary of structure-acoustic coupled cavity were studied using sequential optimization on this study.

Apartment houses are repidly being assimialated into the Korean lifestyle. Little study of space utilization and specificially built-in storage needs has been implemented into design of these apartment units. The purposes of this study were, first, to ascertain attitudes of a select group of Korean housewives(N=250) living in apartments in Seoul toward closets and built-in storage units, and second, to determine the acceptability of proposed alternative plans which include built-in storage facilities by Korean women(N=31) living in the United States. Overall results reflect that built-in closets and storage are highly prized and additional units required in Korean apartment plans. Of the respondents, about 86% thought portable storage bought at marirage would be phased out if more storage was built into Korean apartmemts. Most Korean housewives would perceive the advantages of built-in storage units, and would prefer differentiated built-in storage units to undifferentiat d ones. Yet attitudes were equally split on the aesthetic value of the elimination of the portable storage. Five Korean apartment plans were drawn to scale then altered through the incorporation of additional built-in storage. These altered plans all received greater then 83% preferences to the existing Korean apartment plans. Additional study needs to be undertaken to address the implementation of additional storage in existing units as well as impact the current space planning concepts related to more built-in storage. Consideration needs to be given to the concerns related to aesthetic value of portable units as part of the study process.

The goal of this study is to quantitatively evaluate the effects of the additional construction of urban railroads. To this end, 1) establish accessibility as a measure of quantitative evaluation of construction effects; 2) select the 'Integration' of Space Syntax as a quantifiable indicator of accessibility; 3) represent the Seoul railroads as a network; 4) calculate the 'Integration' form the network before and after the additional construction of the urban railroads. By calculating the change of the 'Integration' of the individual nodes and the change of the sum of the 'Integration' of given zones, the change in accessibility of a particular node and the change in accessibility of a particular region were calculated. After analyzing the change in accessibility in nodes and areas as well, it was confirmed that the additional construction of urban railroads was improving accessibility as a whole of Seoul. It was also identified that there was a degree of difference in the extent of the accessibility change for the different areas. It is particularly noteworthy that changes occur in the accessibility ranking. While certain regions were improving relative rankings, others fell in rank. With this finding, it could be argued that active consideration of the areas in which the relative decline occurs is needed when the planned urban railroad is being built.

The number of household living alone including young single adults has gradually increased. The purpose of this study is to examine the demand on housing options, additional space, shared space, community facilities, housing service for young adults living alone including college students. A total of 180 questionnaire were collected and analyzed. For housing location, commuting distance is the most important feature and amenities are the second important feature. For additional space, there is a significant difference between male and female single residents. Female residents want to install dress room most while male adults want to have a study room. For the shared house option, single adults concerns housing fee and living cost most. However, female adults concern safety and security issues much more than male ones do. The degree of preference to community facilities varies between male and female single residents. The findings suggest more differentiated approaches are needed for alternative housing options for male and female residents.
