The purpose of this study was to identify frailty profiles based on physical, psychological, and social domains of functioning and to examine the associated factors showing the differences among frailty profiles. Respondents were 70 years and older(n=403) and latent class analysis was applied to determine the optimal subgroups based on Tilberg Frailty Indicators which comprised of three domains(the physical, psychological, and social domain). Also, we performed multinominal logistic regression analysis to find out factors making differences among frailty profiles. Latent class analysis(LCA) identified three distinct types: multi-frail type(27.0%), psychologically frail type(26.8%), inadequate support type(46.2%). All three types had common difficulties in dealing with daily life problems and did not receive enough help with theses difficulties. Based on the results of the LCA three-class models, people in multi-frail type accumulated problems in physical and psychological domains and had partially social domain. On the other hands, psychologically frail type showed a relatively high anxiety disorder and depression. Lastly, people in inadequate support type reported the lack of helps, but they were relatively healthy. Comparing these groups with inadequate support type, people with multi-frail had lower educational level, poor nutritional management status and were less likely to participate in labor market. People in psychologically frail type were more likely to be male, to live in big cities rather than middle and small cities, and less likely to smoke. Based on these results, our results showed the multifaceted concept of frailty among Korean elderly people and we suggested several implications for preventing frail process.

My suggestions in this paper come out of the review of the records on the Korean-Japanese negotiations(1952-1965). Before January 2002, the enforcement of the public records law, we had a poor management system of the diplomatic records. For a long time the diplomatic records of Korean government has not been preserved and managed according to the international and professional standards. So many important records have been probably lost and unsuitably classified, preserved for the future use. By the coming of public records law this deplorable situation in the management of diplomatic records has been much improved. However the registration, classification, compilation, based on the principle of provenance were not so sufficiently realized. It is now very urgent to employ more archivists in the relevant governmental institutions and organizations, and to introduce the concept of record group for the management of diplomatic papers. Also at the preparatory work for the publication of the diplomatic papers it is strongly needed to make a room for the participation of the civil experts such as historians, archivists and political scientists. In the case of publication of the Korean-Japanese papers it is also necessary to take the relevant American and Japanese governmental records on Korean-Japanese negotiations and private records of the actors of the times into account. Moreover it must be also seriously considered to start a big project for the elaborate edition of the important records of the foreign policy of the nation.

The APR1400 (Advanced Power Reactor 1400MW) nuclear power plant is a large-scale national infrastructure facility with a total project cost of 8.6 trillion won and a project period of 10 years or more. The total project area is about 2.17 million square meters and consists of more than 20 buildings and structures. And the total number of drawings required for construction is about 65,000. In order to design such a large facility, it is important to establish a design standard that reflects the design intent and can increase conformity between documents (drawings). To this end, a design bases document (DBD) reflecting the design bases that extracted in regulatory requirements (e.g. 10CFR50, Korean Law, etc.) is created. However, although the design bases are important concepts that are a big framework for the whole design of the nuclear power plant, they are managed in 2-dimensional by the experts in each field fragmentarily. Therefore, in order to improve the usability of building information, we developed BIM(Building Information Model) based 3-dimensional design bases management system. For this purpose, the concept of design bases information layer (DBIL) was introduced. Through the simulation of developed system, design bases attribute and element data extraction for each DBIL was confirmed, and walls, floors, doors, and penetrations with DBIL were successfully extracted.

Supply chain management(SCM) requires efforts to search for methods for mutual growth with partner companies and to maintain continuous cooperative relations in order to gain a competitive edge. Because information competencies play a big role within the supply chain, it is essential to examine the relationship of information sharing and partnership quality that can affect information competency. In order to maintain continuous business relations between partner companies, it is necessary to identify the obstacles with partner companies resulting from the imbalance of power within a supply chain and to take on a strategic approach for effectively managing such obstacles. Therefore, there is a significant need to discuss strategic approach methods to enable the logic of mutual growth through the CSV that is worth learning from the partner company and the attributes of non-mediated power. CSV will be reviewed from various aspects as a new management paradigm in the future. This study aims at suggesting a continuous growth model for companies by solving social problems through the integration of CSV and the concept of non-mediated power to advance the information competencies of SCM. A total of 142 copies of survey forms for SCM Implementation Companies were using the PLS structural equation modeling for an analysis, and the following are the findings. Results of this study showed that both CSV and non-mediated power had significant impact on information sharing and partnership qualities, and the conclusion that it is possible to enhance information competency through information sharing and partnership quality. Based on this, this study proposes the implication that it is necessary to elevate awareness of CSV and non-mediated power as variables for the coexistence of SCM participating companies.

The existing selected station analysis (SSA) method analyzes the link transfer mode data between origin and destination of individuals passing through stations from a microscopic standpoint. As such, existing SSA is insufficient as it uses integrated analysis using macroscopic data such as subway lines. This research builds a line chain OD based on path search of individual passenger's movement through the subway, and explores means to utilize the findings. First, a method is proposed that searches the traversed subway path from the linked passage modes that the passenger uses and applies the results to SSA line analysis. Compared to the existing SSA, this method provides for analysis of commonly conflicting features such as the line on which the station is passed, and the stations included on the line thanks to the presence of complete information of the individual passenger's traversed path. It also allows for integrated observation of the line chain OD that approaches a certain station. For enhanced understanding, Seoul Metro Line 9 is used as a case study to demonstrate the integrated formulation concept of line chain OD centered around a certain station as well as the macroscopic features of the traversed path that approaches stations included on the line.

As the dependence of technology on the economic structure increases, the importance of National Core Technology is increasing. However, due to the nature of the technology itself, it is difficult to determine the scope of the technology to be protected because the scope of the relation is abstract and information disclosure is limited due to the nature of the National Core Technology. To solve this problem, we propose the most appropriate literature type and method of analysis to distinguish important technologies related to National Core Technology. We conducted a pilot test to apply TF-IDF, and LDA topic modeling, two techniques of text mining analysis for big data analysis, to four types of literature (news, papers, reports, patents) collected with National Core Technology keywords in the field of Display industry. As a result, applying LDA theme modeling to patent data are highly relevant to National Core Technology. Important technologies related to the front and rear industries of displays, including OLEDs and microLEDs, were identified, and the results were visualized as networks to clarify the scope of important technologies associated with National Core Technology. Throughout this study, we have clarified the ambiguity of the scope of association of technologies and overcome the limited information disclosure characteristics of national core technologies.

This study, as a purpose of base study for landscape redevelopement of Seowon, pointed out problems of planting patterns in each sector and suggested an alternative through analyzing old literature, complete enumeration survey in each sector and taking aerial images. the conclusions drawn from this study are as follows. A Pilam Seowon(historic site no 242) is located in a Pyungya-Sanrok(plain and mountain) district in Jangsung-gun and has Junhak-Humyo(Study room in the front and Shirne in the back) type. 23 taxonomic group of arbor, 6 taxonomic group of shrub and 5 taxonomic group of flowers are planted high-densitily in limited flat surface. It can be classified into being planted by family and being planted through landscape redevelopement in 1980s. Korean traditional trees are planted in this area like Pinus densiflora, Juniperus chinensis L., Thuja orientalis L., Zelkova serrato Makino, Sophora japonica L., Lagerstroemia indica, Prunus mume include Ginkgo biloba which is old big tree and is registered in Jangsung-gun as protected trees. The tea tree in this area was introduced from wild tea plantation in Yonhwa moutain and was planted. From now on, we have to pay consideration a form management of planted trees in the historical area, rearrangement of plant density due to over planting, removal of alien trees like Pinus bungeana and Canna generalisa, prevention a dwarfishness of main area due to over planting in outside facilities, recovery a alienation among each planting area, and planting concept from plants drawings on wall of buildings can be suggested. The implications of this case study is that introduction of over planting can make more problems like losing sense of place. Therefore, we must do a actual state survey on traditional landscape area like Seowon from preservation point of view.

The purpose of this study is to interpret the landscape characteristics of Changdeokgung's rear garden with the idea of Yijing(意境) the way to have a sense of an imaginative object. A term of Jing(境) in Yi-jing means a boundary of man's consciousness. On the boundary of consciousness for an imaginative object, there is a situation of man's emotion to be called Qingjing(情境) to meet an object, and beyond Qingjing, there is Yijing, a consciousness of the idea and the truth. The Structure of the Yijing is an analytical framework in this study. It is clarified that the idea of Yijing and landscape characteristics of changdeokgung's rear garden to analyze works of kings and related historical documents. In result, there were three kings named Injo, Sukjeong and Jeongjo who played big roles to develop the rear garden. First, Injo had built physical structure of the rear garden, the second Sukjong enjoyed Qingjing with composing the poems of Sangrimshipkyoung(上林十景), Jeongjo clearly had made a boundary of idea of Yijing broaden. It is an effective way to interpret imaginative characteristics of our traditional landscape through the concept of Yijing the useful way to understand and systemize a subject of idealistic consciousness.

In the era of the 4th industrial revolution, public libraries need a strategy for promoting intelligent library services in order to actively respond to changes in the external environment such as artificial intelligence. Therefore, in this study, based on the concept of artificial intelligence and analysis of domestic and foreign artificial intelligence related trends, policies, and cases, we proposed the future direction of introduction and development of artificial intelligence services in the library. Currently, the library operates a reference information service that automatically provides answers through the introduction of artificial intelligence technologies such as deep learning and natural language processing, and develops a big data-based AI book recommendation and automatic book inspection system to increase business utilization and provide customized services for users. Has been provided. In the field of companies and industries, regardless of domestic and overseas, we are developing and servicing technologies based on autonomous driving using artificial intelligence, personal customization, etc., and providing optimal results by self-learning information using deep learning. It is developed in the form of an equation. Accordingly, in the future, libraries will utilize artificial intelligence to recommend personalized books based on the user's usage records, recommend reading and culture programs, and introduce real-time delivery services through transport methods such as autonomous drones and cars in the case of book delivery service. Service development should be promoted.

After the first to present projected moving pictures to audiences, the film industry has been reshaping along with technological advancements. Through the full-scale introduction of visual effects-oriented post-production and digital technologies in the film-making process, the film industry has not only undergone significant changes in the production, but is also embracing the cutting edge technologies broadly and expanding the scope of industry. Not long after the change to digital cinema, the concept of artificial intelligence, first known at the Dartmouth summer research project in 1956, before the digitalization of film, is expected to bring about a big transformation in the film industry once again. Large volume of clear digital data from digital film-making makes easy to apply recent artificial intelligence technologies represented by machine learning and deep learning. The use of artificial intelligence techniques is prominent around major visual effects studios due to automate many laborious, time-consuming tasks currently performed by artists. This study aims to predict how artificial intelligence technology will change the film industry in the future through analysis of visual effects production cases using artificial intelligence technology as a production tool and to discuss the industrial potential of artificial intelligence as visual effects technology.
