As information technology advances rapidly, various smart devices are becoming an essential element in our lives. Smart devices are providing services to users through applications up on the operating system. Operating systems have a variety of rules, such as scheduling applications and controlling hardwares. Among those rules, it is significant to protect private information in the information-oriented society. Therefore, isolation task, that makes certain memory space separated for each application, should highly be guaranteed. However, modern operating system offers the function to access the memory space from other applications for the sake of debugging. If this ability is misused, private information can be leaked or modified. Even though the access authority to memory is strictly managed, there exist cases found exploited. In this paper, we analyze the problems of the function provided in the Android environment that is the most popular and opened operating system. Also, we discuss how to avoid such kind of problems and verify with experiments.

In Space contains valuable natural resources. These provide a compelling reason for entrepreneurs, investors, and governments to pursue space exploration and settlement. The Outer Space Treaty of 1967 explicitly forbids any government from claiming a celestial resource such as the Moon or a planet. Article II of the Outer Space Treaty states that "outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means." The U.S. Commercial Space Launch Competitiveness Act of 2015 (CSLCA), however, makes significant advances in furthering U.S. commercial space industry, which explicitly allows U.S. citizens to engage in the commercial exploration and exploitation of 'space resources' including water and minerals. Thus, some scholars argue that the United States recognizing ownership of space resources is an act of sovereignty, and that the act violates the Outer Space Treaty. This paper suggests that it is necessary to guarantee the right to resources harvested in outer space. More specifically, a private ownership of extracted space resources needs to promote new space business and industry. As resources on Earth become increasingly difficult and expensive to mine, it is clear that our laws and policies must encourage private appropriation of space resources. CSLCA which addresses all aspects of space resource extraction will be one way to encourage space commercial activity.

The purpose of this study was to explore behavioral patterns on residential spaces such as the patterns of residential space usage and perception on residential spaces. A questionnaire survey and interview were conducted with 426 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Seoul, Busan, and Gwangju, during the month of September in 2004. The data was analyzed with frequency, factor analysis by using the SPSS 10.0 for windows, and with proc iml by using SAS. The major findings of this study were that: 1) The most typical activities in the Anbang are $\ulcorner$sleeping and getting dressed$\lrcorner$, $\ulcorner$family communication and T.V. watching$\lrcorner$, and $\ulcorner$private affairs$\lrcorner$ ; Anbang(master bedroom) has been perceived and used as couple's private area. 2) Living room was used as a multi-purpose room carrying out various activities such as $\ulcorner$family interaction$\lrcorner$, $\ulcorner$entertaining guest with meals$\lrcorner$, $\ulcorner$children's private affairs$\lrcorner$, $\ulcorner$private affairs$\lrcorner$, $\ulcorner$hobby activities$\lrcorner$, $\ulcorner$clothes management$\lrcorner$, $\ulcorner$couple interaction$\lrcorner$, and $\ulcorner$occasions$\lrcorner$. 3) The representative patterns of activities in dining-kitchen was food $\ulcorner$preparation$\lrcorner$, and the need for social interaction in DK has been growing. The patterns of residential space usages can be used to develop and evaluate the unit plan of Korean middle-size apartment.

Nursing Homes are different from other medical facilities, because they have a living space. And most of residents in a nursing home have dementia, therefore nursing homes are in control of outdoor activities for resident's safety and most of residents live in the living room at the daytime. The purpose of this study is analysis of spacial behaviors of residents in the living room, and reflection of the analysis into the architectural plan of nursing homes.There are two activities, individual activity and social interchange activity, in a living room and the role of a living room is semi-private space that includes both of them. Most numerous activities are watching TV and take a eat. Activities are different in accordance with the position at the living room. Individual activity and social interchange activity is same ratio in the middle and the ratio of social interchange activities are more than individuals in outside of living room. but alcove use of private.The types of living rooms are distinguished by combination of functions of livingroom, activity-room, and diningroom. The activity of use of residents have been shown different phases following the types of livingroom. The type of combination has been seen high rate of use and private activities and social communications are expressed evenly. The type of mixing has been seen low rae of use, but two activities, the above, are equal. The type of separation has been seen not only low rate of use, but also there has been only private activities.

This study tracked the changing process of unregistered private house gardens by using the form at the time of the construction of gardens as the prototype of each garden, investigated the spatial value of the garden, and discussed the historical spatial value of unregistered private house gardens in terms of inheritance and change of traditional gardens. To this end, targeting on unregistered private house gardens in Gangwon-do, which are in danger of preserving their gardens due to the recent increase in the number of designated cultural heritage dismantled, the patterns of unregistered private house gardens, their characteristics and values were identified through the spatial change of the garden, and the following results were derived. First, the unregistered private house gardens were able to inherit and maintain the form of a traditional garden, being located in a clan village. The garden space was divided by the influence of Confucian philosophy, and the components of the garden, tree species and planting methods appeared differently. In other words, the use of garden components according to the status hierarchy appeared. Second, space reduction was continuously confirmed at four target sites. The reduced spaces are garden spaces, and part of the garden was attributed to the state due to the building of new road and environmental improvement project. The reduced spaces are garden spaces, and part of the garden was attributed to the state due to the new road and environmental improvement project. Third, eight old big trees over 100 years old were identified in three of the four target sites, and the garden components such as stone water tanks, quickset doors, and ponds were commonly identified in Korea, China, and Japan during the Joseon Dynasty, inheriting the historicity of the traditional garden.

Hospital architecture is in a transitional period and faces a great change. Furthermore, patients' demand on medical service has been changing. It is said that the importance of public space for people as well as that of private space for patients, doctors and nurses becomes more important than ever. For example, corridor space becomes pathway, waiting room and rest area of patients. Accordingly, the importance of corridor space of public space in general hospitals is increasing. This study aims to present standard data for hospital planning by analyzing space allocation and floor area of corridor space in general hospitals.

Korean urban traditional housing abandoned by the social apathy promptly disappearing form our sight, or ruining. It tells that the strategies we are using today are impossible to fulfill socio-economic needs of residents here. So it needed to find out the strategies which can change this place better to live in. Consolidating the street parking lots fer cars can be one of the important solutions to the area. By using cul-de-sac, after setting up small unit of communities, we will have chance to have a small public space, and at the same time it can help to set up our tradition of people's intimacy inside the community. Most people have their own cars, and the need of parking lots becomes more serious. So, a meeting place like public well in the past must replace parking lots. On the other hand, it is important to re-consolidate existing land to obtain appropriate land size for other uses. Today, the use of private space (house, private lots, etc..)and public space(streets, local offices) is very important. NIMBY (Not In My Back Yard) attitude should also be reconsidered. All these negative social aspects come from negative social relationship, thus we should consider them with care and deep understandings. The traditional housing of Korea should not be abandoned as slum, but this should be transformed in terms of the conservation since it is superior in its ecological and energy conservation aspect.

The purpose of this study was to establish the more rational and practical basic theory for the landscape planning in the aparment complex. In this study, the actual conditions of exterior space, the residens' satisfaction degree and the correlation between exterior space and the residents' satisfaction defree were investigated and analyzed on the 13apartment complexes in Taegu City. Through the statistical analysis, the main results were obtained as fellows : It was found that the size of green area ratio in the apartment complexes were in the order of Jugong Apt. (Korean Housing Corporation), Siyoung Apt. (City Operation), Minyoung high-rise Apt. (Private Business) and Minyoung low-rise Apt. (Private Business) complex. The highest ratio of footway and Parking area were shown in Minyoung high-rise Apt. complex. The important factors at the exterior space of apartment complex were composed by 6 major factors, importance degrees of which are Visual, Practical, Convenient, Sentimental, Recreational and Spatial factors for teenagers in orders. The residents' satisfaction degrees to the exterior space were highly correlated with the spatil organization, size of green area and quantity of trees, view, management situation, defensibility of outside noise, rest place, water landscapings by turns. In order to get more than the average satisfaction degree 18 exterior space, the green area should be occupied by 35% of the apartment complex area and more than 76% of the green area (i. e. 16% of the apartment complex area) should be planted with trees. In the Taegu City regulation, the ratio of tree composition is proposed for only the number of tree. But it was shown that the satifaction degree are more correlated with the species and afforestation of trees than the nuts her of trees in this study. therefore, the species of tree and the afforestation of tree should be considered when the landscape planning of the apartment complex begins. It was found that the ratio of afforestation to make the more desirable exterior space In the apartment complex shoule be 8 to 2 in the ratio of arbor to shrub. It was also required that 30 species of arbor and 15 species of shrub should be planted for the more desirable landscape of the apartment complex.
