The contemporary concept of publicness is reinterpreted from the point of view of contemporary publicness. Contemporary perception of public space has now branched and grown into a multitude of non-traditional sites with a variety of programs in mind. In this study, the aim is to discuss how contemporary public library has been evolved as public space and how to create User-centered interaction. In the case of developed countries, the Public Libraries have showed the expected effects because they have more systematic and efficient plan. Also, these libraries are placed with each facility, not distributed separately. It promotes the accumulation of profit on the space and Increases the efficiency. They support more effectively users' activities through the linkages between each facility and create the active interaction between users. Formation of the various interactions and synergies between space had been induced. Publicity means that the state will relate a combination of a number of specific public area. In addition, open space, public place, shall be directed to: This place as one of the users in order to have meaning, must be equipped with the facilities and space to communicate and understand the local role. Methods of the study are to analyze the concept and role of the users with the concept of modern publicity, to examine the concept of multi-complexity of public libraries for the user-oriented publicness, to learn about the characteristics of public spaces in the public libraries that appear in the advanced countries, to examine how to affect these characteristics in the public libraries, and to suggest the possibility and the various application methods on the characteristics of a public space. In the end, the public libraries for the realization of the publicity, support program complexity such as education and culture, welfare facilities, and public service facilities. In the 21st century, these complexity to improve the quality of service in public libraries. These spaces can be an alternative to be kept comfortable in a more vibrant area, and can affect the social, natural, cultural, and environmental aspects of the physical environment and the objects and relationships, as well as expand.

This study suggested that the concept of creative zone raised by the national interest of the 'Creation' should be extended in public libraries. The concept of creative zone in public libraries was analyzed on the basis of 'Con-creative structure ontology' by Rombach. As we understand a creator and creation as the relation of 'subject'-'object', The current concept of 'Creation' dilutes the possibility of 'Autogenese' that all beings as a subject possess. But 'Con-creative Structure' describes the process of 'Autogenese' through sharing and mutual communication of all beings. The formation process of Con-creative Structure corresponds to the philosophy of the library that supports the self-growth through communication and sharing. 'Co-working Space' is more suitable for the substantive image of Con-creativity than 'Makerspace'. Therefore, this study analyzed circumstances of creative zone in public libraries and Co-working Space in business areas and provided the conceptive and substantive modeling for Co-working Space in public libraries.

Background: There is no consensus on the definition of primary care in South Korea. This study's objective was to define the concept of primary care using a Delphi method. Methods: Three expert panels were formed, consisting of 16 primary care policy researchers, 45 stakeholders, and 16 primary care physicians. Three rounds of voting, using 9-point appropriateness scales, were conducted. The first round involved rating the appropriateness of 20 previously established attributes of primary care. In the second round, panelists received a summary of the first-round results and were asked to once again vote on the 10 undetermined attributes and the provisional definition. The final round involved voting on the appropriateness of the revised definition. The Korean Language Society reviewed the revised definition. Results: Four core (first-contact care, comprehensiveness, coordination, and longitudinality) and three ancillary (personalized care, family and community context, and community base) attributes were selected. The Korean definition of primary care was accomplished with all three panel groups arriving at a 'very good' level of consensus. Conclusion: The Korean definition of primary care will provide a framework for evaluating performance of primary care in South Korea. It will also contribute to resolving confusion about the concept of primary care.

Sinkhole subsidence occurs over abandoned mine workings and can be detrimental to human lives, damage to properties and other surface structures. In this study, simulation of sinkhole development process is performed using special finite element procedure. Especially, creation of mine voids due to roof falls and generation of goaf from broken rocks are simulated using active-passive-active finite elements. An active or solid element can be made passive or void once the tensile failure criterion is satisfied in the specified sinkhole formation zone. Upon completion of sinkhole development process, these passive elements in again be made active to simulate goal region. Several finite element models are analyzed to evaluate the relationships between sinkhole formation with width of gallery. depth of mine, roof condition and bulking factor of roof rocks. This study demonstrates that the concept of passive elements in numerical analysis can be used effectively for analyzing sinkhole formation or roof fall phenomenon in general.

The aim of this paper is to explore the formation of the Seoul-focused network city for technological commercialization compared with Seoul as a mega city. The growth of Seoul and subsequently, the Seoul metropolitan region as a mega city and mega region has led the uneven regional development in Korea since the 1960s. To reduce a huge gap between the Seoul metropolitan and the non-metropolitan region, the concept of network city can be suggested in terms of the functional and spatial division of labor. More specifically, such division of labour throughout the formation of the Seoul-focused network city concentrates on technological commercialization which is deeply concerned with R&BD (research and business development). For this network city, there are 4 axes such as the axis of South-North Korean cooperation (the axis of R&BD for complex technologies), that of the expansion of a mega city (that of R&BD for green growth technology), that of the linkage of small and medium-sized cites (that of R&BD for life science and technology) and that of megalopolis (that of R&BD for basic technology) with regards to the axis of urban development and technological specialization. It shall be argued that the formation of Seoul-focused network city can be an alternative to the contemporary uneven regional development between the Seoul metropolitan and non-metropolitan region in Korea.

Though identity formation is a major developmental task during adolescence and ethnic identity is an integral part of one's identity formation, little is known about ethnic identity exploration and formation among the immigrant adolescents as well as the adolescents born in marital-immigrant families living in Korea. Seventeen adolescents aged 13 to 17 having immigration experiences participated in the study and shared their experiences related to ethnic identity. Results of analyzing in-depth interview data indicated that the concept of ethnic identity was a multidimensional construct: self-identification, bases of identification, emotional reactions, and process of identity formation were important components consisting of the participants' ethnic identities. The youths also reported a variety of socio-cultural experiences related to one's ethnic identities. Based on the findings, the study discussed theoretical implications of the findings and suggestions for providing services for these youths.

Drone was originally developed for air force aircraft or missile exercise shooting targets, and is being considered as the entire unmanned aircraft to the public. The core concept of a drone can be divided into 'unmanned' and 'aircraft'. However, there are many questions about whether the Fourth Industrial Revolution, expressed as a convergence scientific innovation, is appropriate at a time when smart cities are proposed as a concept of new urban spatial formation, and the role of self-driving vehicles, including drones, is being emphasized within the new urban integrated transport system. In this study, the concept of the existing drones was analyzed for the development process, definitions in each country's laws, and the results of the preceding research to present a concept suitable for future society and a unified term. It is not desirable to define a drone for the purpose of a country, an institution, or an operating entity, depending on the circumstances of the era. It is more reasonable to find the concept of a drone based on human life than in the traditional way, and more reasonable considering the development of the drones in the future. Subsequent studies should be more detailed, more data and research results analyzed, and discussed areas that were not covered in this study. Based on this, research should also be conducted on a variety of topics, including legislation, preparation of operational regulations, and related industrial processes and regulations.

Purpose: The purpose of this study was to evaluate exophytically vertical bone formation in the mandibular premolar area of beagle dogs by the concept of guided bone regeneration with a titanium reinforced e-PTFE membrane combined with human demineralized freeze-dried bone. Materials and Methods: Four one-year old beagle dogs were divided into control and experimental group. All mandibular premolars were extracted and surgical vertical defects of 5 mm in height were created in the extracted sockets. At 8 weeks after the extraction, TR e-PTFE membrane sized with 8 mm in length, 5 mm in width, and 4 mm in height was placed on the decorticated mandible, fixed with metal pins and covered with full-thickness flap and assigned as control group. In experimental group, decorticated mandibule was treated with TR e-PTFE membrane and human demineralized freeze-dried bone. The animals were sacrificed at 16 weeks after the regenerative surgery, and new bone formation was assessed by histomorphometric as well as statistical analysis. Results: Average of new bone formation was 38% in the control group, whereas was 25% in the experimental group (p<0.05). Average of connective tissue formation was 42% in the experimental group, whereas was 30% in the control group (p<0.05). The lamellar bone formation with haversian canals was observed in the both groups. In the experimental group, the particles of human demineralized freeze-dried bone were observed after 16 weeks and complete resorption of graft was not observed. Conclusion: On the basis of these findings, we conclude that titanium reinforced e-PTFE membrane may be used alone for vertical guided bone regeneration, but demineralized freeze-dried bone has no additional effect on vertical guided bone regeneration.

The purpose of this study was to evaluate exophytically vertical bone formation in rabbit calvaria by the concept of guided bone regeneration with a custom-made porous titanium membrane combined with bone graft materials. For this purpose, a total of 12 rabbits were used, and decorticated calvaria were created with round carbide bur to promote bleeding and blood clot formation in the wound area. Porous titanium membranes (0.5 mm in pore diameter, 10 mm in one side, 2 mm in inner height) were placed on the decorticated calvaria, fixed with metal pins and covered with full-thickness flap. Experimental group I was treated as titanium membrane only. Experimental group II, III, IV was treated as titanium membrane with BBM, titanium membrane with DFDB and titanium membrane with FDB. The animals were sacrificed at 8 and 12 weeks after surgery, and new bone formation was assessed by histomorphometric as well as statistical analysis. 1. Porous titanium membrane was biocompatable and capable of maintaining the regeneration space. 2. At 8 and 12 weeks, all groups demonstrated exophytic bone formation and there was a statistical significant difference among different groups only at 12 weeks. 3. The DFDB group revealed the most new bone formation compared to other groups (p<0.05). 4. At 12 weeks, DFDB and FDB groups showed the most significant resorption of graft materials (p<0.05). 5. The BBM was not resorbed at all until 12 weeks. 6. The fixation metal pin revealed excellent effect in peripheral sealing. On the basis of these findings, we conclude that a porous titanium membrane may be used as an augmentation membrane for guided bone regeneration, and DFDB as an effective bone forming graft material. The fixation of the membrane with pin will be helpful in GBR technique. However, further study is required to examine their efficacy in the intraoral experiments.
