The purpose of this study is to evaluate the effectiveness of the theme collection service in public library from the user's perspective. To this end, based on prior research, the effect elements of the theme collection were derived from the service use, librarian, and library level. A questionnaire survey was conducted on 294 users of A public library. The collection satisfaction of users who know the theme collection was higher than those who did not, and showed high recognition for the satisfaction with the use of new and unexpected books. In addition, it was found that the positive recognition tended to be high among users who have been using the library for a long time and frequently use the library service. Based on the users' perception and evaluation of the theme collection, the direction of development of the theme collection service was suggested in terms of collection development, collection use and information service, user-centered classification, and awareness improvement of libraries and librarians.

Donggang Su-ho Jo(1924-2016, hereinafter referred to as "Donggang") was a calligrapher and literarti painter who was active in recent times. When he survived, he was called the first teacher respected by all in the field of world calligraphy. His perception of beauty is due to the art view embodied by human instinct. In particular, he considered writing and painting as art of contact(接), which means connecting. Therefore, the meaning of contact(接), is recognized as a kiss between men and women or love affair(雲雨之情). In this way, his literarti painting originated from a wide range of concerns and quests for art. He recognized the principle of art creation from a universal and general perspective on beauty. Based on this, the significance of true artistic spirit and art philosophy was established. If you observe the literarti painting of the Donggang with bamboo's literati painting and orchid's literiti painting, his bamboo's literati painting has the aesthetics of lusterless(無潤), and difficulty obscurity(苦澁). His orchid's literati painting is appreciated refinement(雅) and harmony(韻) made vulgar appearance(俗). His character and scolarship became his literarti painting.

LiDAR plays a key role in autonomous vehicles, and to improve its visibility, it is necessary to improve its performance and the detection objects. Accordingly, this study proposes a shape for traffic safety signs that is advantageous for self-driving vehicles to recognize. Improvement plans are also proposed using a shape-recognition algorithm based on point cloud data collected through LiDAR sensors. For the experiment, a DBSCAN-based road-sign recognition and classification algorithm, which is commonly used in point cloud research, was developed, and a 32ch LiDAR was used in an actual road environment to conduct recognition performance tests for 5 types of road signs. As a result of the study, it was possible to detect a smaller number of point clouds with a regular triangle or rectangular shape that has vertical asymmetry than a square or circle. The results showed a high classification accuracy of 83% or more. In addition, when the size of the square mark was enlarged by 1.5 times, it was possible to classify it as a square despite an increase in the measurement distance. These results are expected to be used to improve dedicated roads and traffic safety facilities for sensors in the future autonomous driving era and to develop new facilities.

As augmented reality technology becomes more common and prevelant, marker-based AR contents are applied in various ways. However AR contents are still hardly utilized due to the low recognition rate of marker images. In order to increase the recognition rate of AR marker images, this paper experiment and analyzed how much the recognition rate of markers could be improved when image correction and design changes was applied. The experimental result shows that the image correction task could significantly improve the number of image characteristics and the recognition grade if the image was modified in a way its saturation value is increased. Moreover, the recognition rate was improved even more when regular pattern design was added to the original marker image. In conclusion, it was possible to make the marker well recognized through proper correction of the image and additional process of pattern design in the process of producing the marker image.

The aim of this study was to investigate whether there is the association between parents residence type and connubial bliss mediated to Korean married women. A total of 3,851 married women were selected from the database of the Fourth Korea Longitudinal Survey of Women and Families(KLoWF) in 2015-2016. In univariate analysis, there was statistically significant differences parents residence type, couple activity, family care and connubial bliss according to socio-demographic characteristics. Moreover, when the parents residence type is short distance, connubial bliss is higher, couple activity is more active and family care is more friendly attitued. By the result of sobel test, parents residence type was indirectly influenced on connubial bliss mediated to couple activity and family care. However, parents residence type was no directly influenced on connubial bliss mediated. The results of these studies will help design policy plans to improve the relationship between spouses and family members in a universal nuclear family society.

Using a Consensus Qualitative Research approach, this study aimed to identify the ageism and explore age-integration as a solution of age discrimination that occurs during the delivery of medical services by nine healthcare professionals who have experience in treating elderly patients. There were two-sided confession has shown by health care professionals about the Ageism. They reported that they don't discriminate by age. However, They also appealed an inconvenience due to the elderly. There were real Ageism in the Healthcare Professional site as a way of Unsuitable care, elderly alienation and dependence on caregivers, polarization of medical service and double discrimination against poor elderly. They found it difficult to offer age integrated health care as a means to mitigate or solve. However they have sought to break barriers to communication, provided a comfortable environment not only for senior citizens but also for all others, and have diversified institutional and service standards. To ensure the healthy life and proper medical service of the rapidly increasing elderly patients, we proposed to do critical review of the factors in the Korean medical system that accelerate the Ageism, reorganization of the health care system for the poor elderly, including the curriculum associated with age-integrating within the health care professional education system, raising the Geriatric Medical Service and the relating professionals and improvements in perception of the health care domains for the elderly and older adults.

is a work of art that was composed through fluid and laminating by being passed down orally for a long time like other ancient songs. As well as, it is given a history of literature's value in the point that it is a Korea's first poetry work, it is considered it casts a long shadow to establishing traditionality of our country's poetry. Even today, has been transformed and recreated into a variety of genres because its literary subject carry the universal emotions and win the sympathy. This manuscript examines modern poetry, modern novel and modern songs that consist of changed ancient song and looks modern writers' perspective about through characteristic that each of works has and then aims checking special situation and meaning that is implicit and recognizing the value of the original. As the has been recreated as modern poetry, it shows the current chaotic situation specifically by embodying it and actively seeks expressing human character, agony and longing, etc, by excluding factor of the original mythical interpretation. Also it rouses situation of reality as detained and repressed. , recreated as modern novel, expands narrative structure and shows portrait of various characters and speaks diverse human condition about reality and suggests plan for dealing with that. Basic emotions of the original is strongly passed to modern popular song . It makes us know that universal emotions which human has across generations can touch people transcending time and space and it is a fresh discovery and possibility that reaffirms the emotion of our people. Ancient song has been studied with emphasis on resignation and grief by focusing on the subject, simply parting and death. But recently, through transformation between a wide range of genres. it carries the spirit of the times that author toward, showing realistic and specific situations. Flexibility of ancient song is expected to continue its vitality transcending generations. Ancient song is assured that it can lead various aspects through active groping in era of change with a various possibility, that the original has, through communication between genres.
