Due to harsh conditions of construction site, understanding of current feature of terrain and other infrastructures is critical issue for site managers. However, because of difficulties in acquiring the geographical information of the construction sites such as large sites and limited capability of construction workers, comprehensive site investigation of current feature of construction site is not an easy task for construction managers. To address these circumstances of construction sites, this study deduce difficulties and applicabilities of unmanned aerial vehicle in the area of construction site management. To confirm applicability of UAV in civil construction project, case study have been conducted on the road construction project. The result of case study proved that the developed system is one of promising technologies that has been studied in construction site management. To improve applicability of UAV for construction and process management information, law and technical issues will be an important area of future study.

This paper tried to examine the implications of the sites of memory and diaspora memory of the life of Jun Itami(Yoo Dong-ryong), a Korean architect in Japan who is interpellated as Zainichi Koreana adopting theoretical and methodological discussions on memory, sites of memory, diaspora, and identity. To this end, the documentary was selected as the subject of analysis. According to the research results, which consists of a total of 48 scenes, is based on the assumption that the sea and Japan and Korea between the sea are the space of memory, and emphasizes that Itami Jun, who had to live as a borderliner and a stranger is disengaged from the borders of nationalities, territories, and countries. In particular, the story of Jun Itami set the sea as a diachronic space(sites of memory) that penetrates the past and present and explores his diaspora identity. The sites of memory of Jun Itami reconstructed in can be said to be a memory space that makes Yoo Dong-ryong more firmly aware of his diaspora identity as a Korean.

As the aging of large domestic SOC facilities accelerates, facility maintenance is also changing from safety evaluation based on the current condition to performance-oriented preventive and preemptive maintenance based on the prediction of the level of future obsolescence. In particular, in the case of bridges, class 1 and 2 bridges are systematically managed along with many studies, but for small and medium-sized class 3 bridges there is no collection and utilization of historical data presenting performance degradation during their service life. Therefore, in this study, 3D model-based demonstration DB system was designed and developed to intuitively check the damage change rate at the damage location by registering the maintenance history by life cycle for each member's exterior damage in the 3D bridge object and to enable API-based comprehensive performance evaluation.

This study examines the housing-related characteristics of unmarried youth using occupational history data from the 10th-14th (2016-2020) youth panel (YP2007) of the Korea Employment Information Service, and the characteristics of housing and employment. Their effect on marriage intention was empirically analyzed. The results of the analysis show that highly educated people, high-wage workers, household heads or economically independent young people, and young people in good financial conditions have a high willingness to marry. Their economic conditions are very important factors. Among the young employed who have become economically independent from their parents, full-time permanent workers, workers at large corporations, and highly waged youth showed a strong desire to get married. On the contrary, young people who are insecure temporary/daily workers, workers at small firms, and low-wage workers show a low willingness to marry. In conclusion, the results imply that young people who are in a vulnerable state in the labor market are giving up or delaying their marriage. Therefore, it is necessary to enhance policies to provide better employment opportunities for youth and, simultaneously, revamp the policy measures to enhance housing conditions.

Records have temporal characteristics, including the past and present; linguistic characteristics not limited to a specific language; and various types categorized in a complex way. Processing records such as text, video, and audio in the life cycle of records' creation, preservation, and utilization entails exhaustive effort and cost. Primary natural language processing (NLP) technologies, such as machine translation, document summarization, named-entity recognition, and image recognition, can be widely applied to electronic records and analog digitization. In particular, Korean deep learning-based NLP technologies effectively recognize various record types and generate record management metadata. This paper provides an overview of Korean NLP technologies and discusses considerations for applying NLP technology in records management. The process of using NLP technologies, such as machine translation and optical character recognition for digital conversion of records, is introduced as an example implemented in the Python environment. In contrast, a plan to improve environmental factors and record digitization guidelines for applying NLP technology in the records management field is proposed for utilizing NLP technology.

Due to various reasons (normally financial constraints in developing countries), it becomes common to change of the business model from state-run projects to Private Investment Projects (Public Private Partnership) in the global railway businesses. However, due to the nature of railroads compared with other types of infrastructure such as roads and others, railway business require considerable construction cost and O&M cost through the business development, construction, and operation and management stages. Therefore, private investment railway projects, especially in developing countries, can be problematic in terms of the potential for uncertainty when return on investment cannot be guaranteed. In order to strengthen the competitiveness of domestic companies when entering overseas railroad PPP projects, this study proposes PPP-related risks and their countermeasures by reviewing global railroad trends and identifying Korea's weakness in managing international railroad projects.

In order to support women with career breaks to re-enter the labor market, it is not only necessary to discover and select promising jobs, but also to provide objective and accurate job information on selected promising jobs so that women with career breaks can make reasonable career choices. need arises. It can be pointed out that the government support course has no burden of tuition compared to the general course, and because the quality of education is high, it is possible to select trainees with a high willingness to find employment through competition in the recruitment process. In addition, the government support process secures relatively high-quality programs and instructors, increasing trainees' concentration, satisfaction, and willingness to find a job. Job literacy and employment preparation education are obligatory, job design support through job counseling, and continuous follow-up support. The system also works. Accordingly, if systematic and continuous development and support are made in the process of selecting promising occupations for women with career breaks and designing education and training programs, it is expected that women with career breaks will be more active in their re-entry into the labor market.

In this paper we define wage premium of college hierarchy as a wage differential among college graduates from different universities within the same graduate cohort and estimate the wage premium of college hierarchy for the three different cohorts: namely, 1982, 1992, and 2002. We utilize a unique data set called Education-Labor Market Lifetime Path Survey, which contains education and labor market information about the three different college graduate cohorts. We find that the wage premium of college hierarchy changes over time for the same cohort. It tends to large right after graduation but decrease with labor market experience. When the test score at the time of college entrance controlled, the wage premium of college hierarchy mostly disappears for the 1992 cohort. But for the 2002 cohort it remains seven years after graduation. The difference in the wage premium of college hierarchy can be explained, at least partly, by the number of colleges, college enrollment ratio, and the relation between college hierarchy and the entrance test score.
