The framework plan for the development of an integrated underground space map was established of preventing ground subsidence. The mapping process is expected to be completed to the level of nationwide municipal government standards by end of this year. To facilitate the utilization of the integrated underground space map, paper-based drawings for specialized organizations in underground safety impact assessment have been provided since September 2018, and services for local government officials have been provided in the underground information utilization system since May 2019. However, the map is utilized based on the information at the time of the initial development of the map, without any updates, thereby resulting in a lack of accuracy and latest information. This has led to a decrease in the utilization and reliability of the information. Therefore, in this study, for the underground structures(subway, underground shopping mall, underground passage, underground roadway, underground parking lot, utility tunnel), which are the key components of the integrated underground space map, a standard format for the submission of completed drawings is designed in accordance with Article 42 (2) of the Special Act on Underground Safety Management, which aims at laying the foundation for establishing the updated system of the integrated underground space map. In addition, through the verification of the automatically updated underground structure data based on the standard format, the reliability of the data can be assured. This format is expected to contribute to the improved utilization of the integrated underground space map in the future.

This study measured and analyzed the propagation characteristics at frequencies 6, 10, and 17 GHz to discover the new propagation demands in a semi-basement indoor corridor environment for meeting the 4th industrial revolution requirements. The measured indoor environment is a straight corridor consisting of three lecture rooms and glass windows on the outside. The measurement scenario development and measurement system were constructed to match this environment. The transmitting antenna was fixed, and the frequency domain and time domain propagation characteristics were measured and analyzed in the line-of-sight environment based on the distance of the receiving antenna location. In the frequency domain, reliability was determined by the parameters of the floating intercept (FI) path loss model and an R-squared value of 0.5 or more. In the time domain, the root mean square (RMS) delay spread and the cumulative probability of K-factor were used to determine that 6 GHz had high propagation power and 17 GHz had low propagation power. These research results will be effective in providing ultra-connection and ultra-delay artificial intelligence services for WIFI 6, 5G, and future systems in a semi-basement indoor corridor environment.

The history of modern libraries in Korea is less than 150 years. Nevertheless, there are various issues about when the word library appeared, how it was transformed, and the name and overall appearance of the library opened by the Busanpo branch of the Nihon Kodo-kai during the enlightenment period. Therefore, this study analyzed and argued many issues. As a result, it was found that the word library appeared in poetry collections, tombstones, and diaries from the early Joseon dynasty. Although it was widely held that the library was first introduced by Yu Gil-jun's 「Seoyugyeonmun, 1895」, it appeared in Lee Hun-young's 「Iisajipryak」 and was also introduced in 「Hanseongsunbo, 1884」. And the first name given to the facility was Kodo library, which was opened by the Busanpo branch on October 10, 1901. Book club, reading club (library), Busan(Busan district) library, Kodo bookstore, Kodo-kai library, etc. which are described in many documents are all errors. The location of the library was a temporary house on a leased site in Seosanhajeong of Yongdusan mountain. And it is presumed that it has secured about one room and 1,000 Japanese and Western books, and provided fee-based services to Japanese residents. Although the Kodo library is not the first public library established by a Korean, it is undeniable that it was the first public library to exist in Korea. Therefore, when defining the character of the Kodo library, it is necessary to have a coolness and discernment beyond national emotions, historical conflicts, and ideological frames.

Objective : This study was to apply a cognitive rehabilitation group program based on sensory activity in patients with dementia living in a facility and to check its effectiveness on cognitive function, depression, and quality of life (QOL). Methods : Sensory-based cognitive rehabilitation group programs (20 sessions) were conducted for eight elderly with dementia over the age of 65 living in a nursing facility located in H-gun, Gangwon-do. The participants' cognitive function, depression level, and QOL were evaluated before and after the program. Results : The mean of Mini-Mental State Examination-Dementia Screening increased; however, there was no statistically significant difference. In contrast, the mean post-test score of the Subjective Memory Complaints Questionnaire decreased, and there was a statistically significant difference (p < .05). The mean post-evaluation score of Short Geriatric Depression Scale measured to confirm the decrease in depression compared to the pre-evaluation score, but there was no statistically significant difference. Finally, the mean post-evaluation score of the World Health Organization QOL assessment instrument-Brief confirmed the change in the QOL, and there was a statistically significant difference (p < .001). Conclusion : This study will provide the basis for suggesting the usefulness of developing a sensory activity-based cognitive rehabilitation group program for dementia patients living in facilities.

The current status of local road pavement management in Jeollabuk-do only relies on the accomplishments of the site construction company's pavement repair and is only managed through Microsoft Excel and word documents. Furthermore, the budget is irregular each year. Accordingly, a systematic maintenance plan for local roads is necessary. In this paper, data related to road damage and road environment were collected and processed to derive possible areas which could suffer from road damage. The effectiveness of the methodology was reviewed through the on-site inspection of the area. According to the Ministry of Land, Infrastructure and Transport, in 2018, the number of damages on general national roads were about 47,000. In 2019, it reached around 38,000. Furthermore, the number of lawsuits regarding the road damages were about 93 in 2018 and it increased to 119 in 2019. In the case of national roads, the number of damages decreased compared to 2018 due to pavement repairs. To measure the priorities in maintenance of local roads at Jeollabuk-do, data on maintenance history, local port hole occurrence site, overlapping business section, and emergency maintenance section were transformed into data. Eventually, it led to improvements in maintenance of local roads. Furthermore, spatial data were constructed using various current status data related to roads, and finally the data was processed into a new form that could be utilized in machine learning and predictions. Using the spatial data, areas requiring maintenance on pavement were predicted and the results were used to establish new budgets and policies on road management.

The demand for spatial information in the era of the 4th Industrial Revolution is expanding Additionally, interest in attribute data related to geography or location is increasing. In the field of spatial information, spatial information policies and services tailored to the public can be provided through linkage and integration with new attribute data, and these data are resources for this purpose. In order to meet this expanding and diverse demand for spatial information utilization, it is necessary to develop technologies for linking and utilizing various attribute information such as public data. In this study, we aim to present a technology development strategy for linking and integrating attribute data and spatial information through a review of theories related to data linkage and integration, the current status of data on public data portals, and existing prior research. As a result, it was suggested that the data identifier of the attribute data to be linked should be used to develop linkage technology between spatial information and attribute data, and an attribute data linkage process that can be used when designing a prototype for technology development was presented.
