Technology that cannot be excluded from 4th industry is self-driving sector. The self-driving sector can be seen as a key set of technologies in the fourth industry, especially in the DB sector is getting more and more popular as a business. The DB, which was previously produced and managed in two dimensions, is now evolving into three dimensions. Among the data obtained by Mobile Mapping System () to produce the HD MAP necessary for self-driving, Point Cloud, which is LiDAR data, is used as a DB because it contains accurate location information. However, at present, it is not widely used as a base data for 3D modeling in addition to HD MAP production. In this study, MMS Point Cloud was used to extract facilities around the road and to overlay the location to expand the usability of Point Cloud. Building utility poles and communication poles DB from Point Cloud and comparing road name address base and location, it is believed that the accuracy of the location of the facility DB extracted from Point Cloud is also higher than the basic road name address of the road, It is necessary to study the expansion of the facility field sufficiently.

Water pollution in erosion control dams is a major issue for forest watershed management, but the effects of erosion control dams on water quality remain poorly understood. In this study, water quality data from streams and dam reservoirs were collected over the Nakdong river basin. Monitored data were further analyzed to examine the relationship between watershed characteristics and water quality. Of the total 43 erosion control dams, less than 10% had lower water quality that was not suitable for agricultural use. TOC and oxygen demand, SS and turbidity, SS and Chl-a, and Chl-a and turbidity showed high correlations (p < 0.01) both in stream water and in detained water. BOD and SS, BOD and Chl-a, BOD and turbidity, and TOC and Chl-a showed high correlations only in stream water. Overall, the results demonstrated that for most erosion control dams the water quality was relatively good. In addition, the quality of downstream water is somewhat affected by the water detained by erosion control dams, in limited ways.

This essay would focus on a kinds of new archival strategy. The main frame has been the kinds of activities regulated by laws, or formal activities since 1999. In the case of presidential archives has no another frame. There had never kinds of presidential archives system until President Noh, if anything. It means that the frame has some important points. Although it is, we have to say about the limits of the frame. This essay show 'metaphor frame' for archival system. I think that we have to guess there are methodologies below the two frames. One is quantitative study methodology, and another is qualitative research methodology. The later focuses on the experiences for making narratives. We have to know that this methodology is out of fashioned in the field of history department and cultural anthropology department for the purpose of alternative studies. This essay says about 'archival field description' and 'narrative records' for the new records in archival field. I have to say about that we needs to discuss about kinds of new archival discours. And to conclude, we should manage the records in culture.

Currently, the Free Trade Agreement(FTA) promoting regionalism or bilateralism has been increasingly concluded, which is against multilateralism of the WTO. The adoption of the TRS under the FTA carries various issues from the rationale of its existence to its contents. To explain these contradictory issues between the WTO and the FTA, this paper studied on the TRS by analyzing present cases and negotiation results of the TRS under the FTA and comparing them under the WTO. The TRS under the WTO agreement is limited only to antidumping, countervailing duties and safeguard as the agreed concept. When the negotiations of the FTA are on the process, it is necessary to adopt the TRS depending on the negotiating party countries of the FTA after considering fully the economic situations of Korea and the need of protection for the domestic industries. Currently, Korea has entered into the FTA with several countries and most of the agreements with respect to the TRS maintain and observe the right and duty in the WTO agreement and when necessary, in some of the FTA agreements, they have changed parts of the TRS. Consequently, it is needed to establish the basis for application of the TRS. Also, additional application of the SSG provision to some sensitive goods is highly recommended.

Drawing upon Vygotsky's theory, this paper explores the possibilities of imaginative education and those implications in relation to emotions. Imagination is an important element of future competencies as well as creativity. But there is a big dilemma in an educational intervention about imagination. If imagination is naturally occurring and therefore considered a mysterious ability that is specific to a child, education should not intervent as much as possible so that it can be expressed and preserved. It is linked to Piaget's influence, which regards imagination as a mental immaturity of childhood. Vygotsky who is a developmental psychologist argues that mind is generated from the socio-cultural origins in opposition to Piaget's spontaneous generation and emphasizes that it is a core characteristic of human to create something through interaction with the world. Vygotsky consider that 'imagination' which synthesizes empirical material and creates a new image is a key factor in human creativity. He reminded us of the possibilities and importance of imaginative education by revealing that imagination is not limited to childhood but constantly develops through cultural experience. Especially Vygotsky's understanding has important implications for future education in relation to emotion. Imagination plays a role of expressing and dealing with human emotions. Unlike the reason-centered society in the past, future society demands a big role of imagination in education for dealing with emotional knowledge and morality.

Currently, the number of bridge structures in Korea is continuously increasing and enlarged, and the number of old bridges that have been in service for more than 30 years is also steadily increasing. Bridge aging is being treated as a serious social problem not only in Korea but also around the world, and the existing manpower-centered inspection method is revealing its limitations. Recently, various bridge damage detection studies using deep learning-based image processing algorithms have been conducted, but due to the limitations of the bridge damage data set, most of the bridge damage detection studies are mainly limited to one type of crack, which is also based on a close set classification model. As a detection method, when applied to an actual bridge image, a serious misrecognition problem may occur due to input images of an unknown class such as a background or other objects. In this study, five types of bridge damage including crack were defined and a data set was built, trained as a deep learning model, and an open set recognition-based bridge multiple damage recognition model applied with OpenMax algorithm was constructed. And after performing classification and recognition performance evaluation on the open set including untrained images, the results were analyzed.

This article aims to identify the characters and theme shown in dance costume and utilize them from an educational perspective by constructing digital museum archiving, which can be systematically collected, classified and stored from dance costume. It deals with definition of digital museum archiving as theoretical background and examples of how to create digital museum archiving as research content. The role that archiving plays in digital museum and effectiveness have been demonstrated. Archive is a term used to indicate extensive material and its storage and referred to as an integrative model of display in the computer-generated space. When it comes to producing dance costume as a form of digital museum, the museum is to be made in the computer-generated area of dance costume. The museum shows each division of major, medium and minor classification. The major classification divides genre of dance performance into Korean dance, modern dance and ballet. The middle involves choreographers, costume designers. The minor categorization includes newspaper, interviews, performance pictures, and programs. Digital museum has the value of space utilization, creation, culture, utilization of multiple educational programs, offering of digital museum content, two-way communication, and program development of the new display form.

The purpose of this study was to understand family changes and dynamics of and to suggest institutional/policy-level tasks for coping with them, by paying attention to changing family values of single-person households and their caring work performed in everyday life. This study selected 11 single-person households residing in Ulsan by considering their age and marital status, and analyzed their overall daily lives, family values, and the characteristics of household work and caring. The characteristics of these single-person households in Ulsan, not only showed the coexistence of "simplicity, but instability" when maintaining and living their own lives, but also showed the ambivalent characteristics of family values by showing a gap between the perception and reality of diversity. In regard to family life, the participants complained of difficulties in "caring and relationship of family of origin" and the "economic factors", and notably showed the "dual value system". For a more stable life, the single-person households were forming social networks to relieve a sense of isolation and loneliness, and to recover relationships, instead of limiting themselves to only the traditional method of family formation. Thus, it would be possible to respond to family changes when changes are promoted in each area of "the perception of life", "family life", and the "family & social relationship", and this research suggests policy-level tasks based on the results of this study.

This Study is about the development of LCC Analysis Model and Evaluation of VE. It was carried out to help the person's intention decision about choosing the pavement construction method that can deal with 'Pavement Life Factor' like Area Character and Traffic Volume efficiently, by considering the total life cycle cost of pavement life cycle happens according to the numbers of public use year. For this, we developed the new LCC Analysis Model by using the Data of Seoul city the representative city in Korea, and carried out VE Evaluation that reflects the opinions of specialists. This Analysis Model consists of cost items that affects directly the choice of pavement construction, except for the common cost items of the various pavement construction. And we investigated the propriety by applying our model to the example line that are used for the public at present. About the base data of cost items that are used for our analysis, we enhanced our model's confidence by using the statistics data of Seoul and the standard data of unit cost calculation.

This work is to review the granite landforms studies by Korean geographers. It is verified that geomorphlogical characteristics of granite present landscapes characterized by 1) in case of mountains, are difficultly or irregularly weathered, so as to develop rocky forms such as domes, cliffs, and tors ; 2) in case of stream valley that is inter-massif lowland, low relief hills and flood plains with alluvium. All these facts owe to the difference of weathering mode granite properties. The granite hills and alluvial plains of southwestern coastal parts in Korean peninsula is low undulatory and large owing not only to the existence of highly weathered granitic regolith, but also to frequent flooding. Cultivated brownish field, orchard, meadow and forest are located at granite hills. On the other hand paddy rice field at granite alluvial plains. Korean peninsula have endured erodible geomorphlogical processes since Miocene when warping it up. Therefore many intermontane basins are located on the weathered granite areas which are surrounded by mountains composed of much less Precambrian gneiss complex. In fact, intermontane basin is mainly linear fault-line valley. The landforms of the intermontane basins are characterized by gentle piedmont slopes, alluvial fans, fluvial terraces and alluvial plains.
