There are many apartment buildings with the government's policy of increasing the supply of residential houses in Korea. Roughly 60% of the Korea population are living in apartment buildings. Since the 1970s, the Korean economy has grown enormously, the economic and social structure was radically transformed to industrialization and urbanization step. A village has grown into a large town in Korea and apartment buildings was constructed to solve national housing shortage by the Korean government and the construction company. Since the 2000s, this apartment buildings which was built in the 1970s and 1980s had become gradually deteriorated. So, reconstruction and remodeling project of apartment buildings have been come into request in Korea. There are two way to improve the residential environment. The one is remodeling of apartment buildings and the other is reconstruction of that. Therefore, we carried out questionnaire and survey study of the preference on the reconstruction and remodeling of old aged apartment which were located in daejeon province. As a result, the preference rate of remodeling is increasing instead of reconstruction because reconstruction of apartment buildings takes more money and needs long construction period.

Large-scale unband development resulted from the rapid economic growth in the Republic of Korea has brought about the habitat destruction for the native animals and plants living in forest and farmland. In order to resolve this problem, it is necessary to consider the natural ecosystem as an organism and to preserve the natural ecosystem by managing ecologically significant habitat consistently. Especially, the local governments should be able to establish regional ecologic networks in consideration of the ecological connectivity and the environmental and ecological excellence, and to reflect them into the local development plans. In regard to this, the methods of the regional ecological network establishment was presented, making use of the results including the national ecological network which assessed the ecological connectivity of the nation and the environmental and ecological assessment results of the Environmental Conservation Value Assessment Map which was designed to analyze and assess the national environmental and ecological values quantitatively. Making use of the case of Gyeongsangnam-do; the results presented that the existing national ecological network in the core region has expanded from $2,986km^2$ to $4,049km^2$ and the existing national ecological network in the buffer region has expanded from $2,940km^2$ to $3,006km^2$. Referring to the regional ecological network in the process of the local development plans could contribute to the increase in biodiversity and the integrated local environmental management including the ecosystem preservation.

For nursing as a science to establish a unique system of knowledge, nursing researchers should include the philosophical activities such as establish of nursing philosophy. For establish of philosophy nursing, the nature and realms and essential characteristics of nursing science should be made clear at first. The purpose of this study identify alienation and the situation of happen to alienation and Martin Buber Philosophy(I and Thou). Understanding of this concept should enlighten nurses to interaction and relationship problems between patients and nurse and thus lead to further toward enhancing these interaction and relationship. The alienation was serious problem in present society which was cultural, political, economical, mechanical, religious classified. The overcome of alienation in nursing situation was caring and interpersonal relationship based on Martin Buber philosophy. The essential philosophy of Martin Buber was "I and Thou" relationship. I and Thou relationship are consist of five characteristics ; 1)mutuality 2)directness 3)presentness 4)intensity 5)ineffability As health care technology becomes more sophisticated, there is a tendency to rely on monitors and machines to assess the patient's status. Therefore focus on the functioning and care of machine can result in less meaningful communication with patients. This study points to the need for health professional and patient relationship based on Martin Buber philosophy(I and Thou). This relationship may suggest that professional shoud have sincerity, concerning, respect and warm emotional toward their patients. Ultimately this study provide the basic information to contribute understanding of "I and Thou" relationship and nursing philosophy development in nursing education.

Forest biomass became a topic because we have growing interest in global environmental issues and environment-friendly energy resources. This study was carried out to estimate the forest biomass and develop a program for biomass information management in Korea. The total forest biomass (million ton) were 521 for gross forest, 403 for productive forest and 201 for commercial forest in 2005. Also, the annual biomass production in forest was 20 million ton which was equivalent to 94,290 Gkcal of heating value and about 9 billion won of paraffin oil. The biomass growing rate (every 10year) increased from 4.95% in 1985 to 5.30% in 1995 but turn down 4.46% in 2005. The factors that the forest stock could be converted to the forest biomass have developed according to forest type. Therefore, it is impossible to estimate the exact biomass by tree species. In this reason, the demands of the development of the factors by tree species was raised. In addition, it is on time to develop an equation for estimation of biomass by species using dbh and height as independent factors.

This paper aims to critically review the geographical literature on learning and proximity that stresses the role of the regions and geographical proximity in sustaining competitive advantage, and to conceptualize a relational/organizational perspective on the sources of knowledge and learning in the firm. In the first part of the paper, I argue that the geographical literature lacks the deliberate scrutiny of how learning occurs in the firm and where the sources of knowledge and learning come from. Secondly, I attempt to elaborate the concept of proximity through a relational/organizational perspective. Thirdly, I delve into how learning takes place and is realized in the firm through communities in the firm such as communities of practice, epistemic communities and task-force teams and how such communities in the firm generate knowledge and sustain loaming by drawing on relational/organizational proximity. This paper concludes by claiming that the sources of learning exist in organizational spaces, with complex geographies mobilizing distributed knowledge and competences and combining varied forms of knowledge beyond the simple demarcation of tacit and codified knowledge.

This research focused on the consciousness and behavior of married-teachers to support their aged-parents. The subject of this study was 239 married-teachers, in the Gyeongnam area, Korea, living with at least one of their old-parents. Statistical analysis was carried out using SPSS/WIN programs including frequencies, t-test, one-way ANOVA, correlation analysis and stepwise regression. The major findings in this study are as follows; 1) Degree of consciousness in supporting married-teachers' aged parents was 3.98 on a scale of 0-5.0. The significant variables affecting the results were sex, living-distance, and familism. 2) Degree of behavior in supporting married-teachers' aged parents was 3.07 on a scale of 0-4.0. The significant variables affecting the results were number of child, living-distance, economic level of aged parents, and self-esteem. 3) There was a close relationship between the consciousness and behavior of married-teachers to support their aged-parents. 4) Stepwise regression analysis showed that the most effective variable of the married-teachers' behavior for supporting aged-parents was supporting consciousness.

Recently top-k query processing has been extremely important along with the explosion of data produced by a variety of applications. Top-k queries return the best k results ordered by a user-provided monotone scoring function. As cloud computing service has been getting more popular than ever, a hot attention has been paid to cloud-based data outsourcing in which clients' data are stored and managed by the cloud. The cloud-based data outsourcing, though, exposes a critical secuity concern of sensitive data, resulting in the misuse of unauthorized users. Hence it is essential to encrypt sensitive data before outsourcing the data to the cloud. However, there has been little attention to efficient top-k processing on the encrypted cloud data. In this paper we propose a novel top-k processing algorithm that can efficiently process a large amount of encrypted data in the cloud. The main idea of the algorithm is to prune unpromising intermediate results at the early phase without decrypting the encrypted data by leveraging an order-preserving encrypted technique. Experiment results show that the proposed top-k processing algorithm significantly reduces the overhead of client systems from 10X to 10000X.

In contemporary society, it is increasingly common to spend more time indoors. As such, there is a continually growing desire to build comfortable and safe indoor environments. Along with this trend, however, there are some serious indoor-environment challenges, such as the quality of indoor air and Sick House Syndrome. To address these concerns the government implements various systems to supervise and manage indoor environments. For example, green building certification is now compulsory for public buildings. There are three categories of green building certification related to indoor air in Korea: Health-Friendly Housing Construction Standards, Green Standard for Energy & Environmental Design(G-SEED), and Indoor Air Certification. The first two types of certification, Health-Friendly Housing Construction Standards and G-SEED, evaluate data in a drawing plan. In comparison, the Indoor Air Certification evaluates measured data. The certification using data from a drawing requires a considerable amount of time compared to other work. A 2D tool needs to be employed to measure the area manually. Thus, this study proposes an automatic assessment process using a Building Information Modeling(BIM) model based on 3D data. This process, using open source Industry Foundation Classes(IFC), exports data for the certification system, and extracts the data to create an Excel sheet for the certification. This is expected to improve the work process and reduce the workload associated with evaluating indoor air conditions.

The purpose of this study was to examine the demographic characteristics, oral health awareness and oral health behavior of 1,356 Korean senior citizens based on the fourth raw materials of the 2008 national health and nutrition survey, and to analyze their DMFS, DMFT and FS-T indexes, which were oral health indicators. The findings of the study were as follows: 1. The mean DMFS index of the Korean senior citizens was 26.62, and their average DMFT index was 6.76. Their mean FS-T index was 21.51. 2. Out of the demographic characteristics of the Korean elderly people, education made statistically significant differences to the DMFS(p<0.05) and FS-T(p<0.001) indexes, and whether they worked or not made statistically significant differences to the DMFT(p<0.01), DMFS(0.001) and FS-T(0.001) indexes. There were no significant gaps according to gender, age and presence or absence of a spouse. 3. The oral health awareness of the Korean senior citizens(subjective oral health status, whether to need a dental treatment, concern for oral health and mastication) had no statistically significant relationship to their DMFS, DMFT and FS-T indexes. 4. Among the oral health behaviors of the Korean elderly people, whether they got a dental checkup over the past year made statistically significant differences to the DMFT(p<0.01), DMFS(p<0.001) and FS-T (p<0.001) indexes, and there were statistically significant gaps in the DMFT(p<0.010, FS-T(p<0.01) and DMFS(p<0.001) indexes according to yesterday's toothbrushing frequency. The time when they went to a dentist made a significant difference to the FS-T(p<0.01) index only.

Recently, our society is seeing cultural value in a new light, perceiving it as an element that creates new values added. Reflecting this trend, the local governments in various levels focus on reviving the regional economies by enhancing cultural competencies and developing the culture and tourism industries. This research is conducted to perform the policy project 'administrative support plans to make Seongnam a hub of international culture and tourism,' which was proposed as part of the urban renewal strategy of the city. This study proposes the establishment of 'policy communities' to build the infrastructure for 'creative cultural content tourism' as a plan to accomplish the policy goal pursued by Seongnam. The focuses include what the policy communities are, how they work, and what the local government has to do with them for a successful implementation of proposed policies, by theoretically examining the composition variables of policy communities. In particular, the study concentrates on how to reconstruct the infrastructure for the culture content technology (CT) in the IT-based city and to transform itself into a city of "creative cultural content tourism". If the policy communities are formed under the proposed model in this paper, it is expected that they will become the viable alternatives in the field.
