This study examines the concepts and policy factors regarding gender-mainstreaming strategies and urban areas that have been discussed in the fields of international norms and development cooperation from the perspective of the Mexican government. It analyzes how gender-mainstreaming strategy is integrated and realized through Mexican law and key programs carried out by Mexico City. Through a literature review, this study builds upon previous research and theoretical discussions. In fact, Mexican federal government is considered to have successfully achieved "gender institutionalization." Within the framework of the law and institutions, the programs promoted by Mexico City aim to realize women's rights and meet their needs in the metropolis, while emphasizing a wider participation by citizens to realize these urban rights. In particular, the government of Mexico City is expanding on policies and programs that focus on strengthening the financial autonomy of women by understanding women's vulnerabilities as inequalities arising in the areas of the economy, space, and time.

Many people create records in digital space, and the amount of digital records left after individual dies has increased. The digital record left by the deceased is different from the record heritage that has physical substances. In many cases, the records of the deceased not just belong to the deceased, and many deceased did not explicitly disclose their online accounts and method of dispose of digital records during their lifetime, so this problem may lead to problems of inheritance to the bereaved family. In addition, digital records may be neglected or deleted after a person's death due to software problems, specific platform's terms of use, account deletion by bereaved family, etc. This leads to the problem that daily records, which are important clues to the social aspects at the time, are easily lost. Several studies have revealed that individuals are interested in preserving their digital records, but do not know how to do it, so they are benign neglect. For this reason, it is necessary to pay attention to personal digital records and personal digital legacy, and to prepare related policies and plans. Accordingly, this study analyzes problems related to the management of digital records after an individual's death, related to laws and systems, the status and policies of platforms and industries, the status of personal record management, etc. Various solutions were suggested, such as a need for enactment for digital personal record management act, platform's explicit policy for individual's post-mortem records, digital records management plan for archival institutions, individual's a preemptive management plan for his/her own records, and a method for writing a will related to digital account information.

This study is a study on the coding mathematics curriculum that converges elementary and middle school mathematics and information subjects and a minimum coding game-based education method for this. For the past 3 years, the coding mathematics curriculum and educational methods to effectively operate the curriculum were studied by applying them to 6th graders of elementary school and 1st graders of middle school. As a result of the first year of research, the coding mathematics curriculum was modified to a coding environment including the mathematical concept of a three-dimensional coordinate space, and the three-dimensional object was improved to be output as a real 3D print. As a result of the 2nd year study, it was improved so that even low-level students can build buildings by introducing different level commands for each component of the building so that self-directed learning is possible. As a result of the 3rd year study, a teaching-learning strategy based on a minimal coding game was designed to induce an increase in the level of computational thinking, and evaluation and feedback for diagnosing computational thinking were developed. Educational methods to promote self-directed learning and computing thinking ability, and researched coding mathematics curriculum are meaningful for the research and practice of the convergence education of school mathematics and informatics.

At the present time, no systematic review has been conducted to report the project's outcomes or trends. This study systematically reviewed existing evidence related with community care pilot project. A total of 61 articles, including 18 original literatures and 43 review literatures were finally selected. For original literatures, the most frequent literatures focused on demand surveys (n=4) and model proposals (n=4), the utilization of touchpoint (n=3), space design and architectural model (n=3), manpower training and role establishment (n=2), followed by prioritizing objectives (n=1) and research trend study (n=1). For review literatures, the most frequent literature focused on the elderly (n=12) and relatively few literature on the disabled and mental illness (n=2). Since the pilot project for community care has been implemented for only about one year, the present study indicates that more future research is needed to the disabled, mental illness, and homeless should be conducted as well as elderly.

Based on the kinetic typography principle and the structure features of Chinese characters, this study took the Chinese'24 solar terms' theme dynamic poster as the research object, explored the visual expression of dynamic Chinese characters, and tried to summarize the visual expression law of Chinese characters in dynamic poster design. It can be found that, there could be 6 different types of Chinese character expressions in the 24 solar terms poster design. Among them, 'Drawing' design method has the meaning of text structure and form expression, and 'Assembling' design method has the meaning of text stroke and texture association, also, 'Forming' design method bring its meaning through stroke deformation, 'Transforming' design method conveys the content through text disintegration, 'Replacing' design method mainly bring the meaning through simulation, while 'Rotation' design method always express through visual three-dimensional and space. Finally, the findings could not only provide analytical logic and methods for the expression of Chinese characters in dynamic poster design, but also fill the lack of formative research on dynamic Chinese characters, which hopefully provide basic information for the research related to dynamic Chinese character structure, as well as the dynamic poster designers.

The special means of transportation introduced to improve the mobility of the transportation vulnerable met the number of legal standards in 2016, but lack of development in terms of quality, such as the existence of long waiting times. In order to streamline the operation of special means of transportation, long-term standby traffic, which is the top 25% of the wait time, was extracted from the Daegu Metropolitan Government's special transportation history data, and spatial autocorrelation analysis and social network analysis were conducted. As a result of the analysis, the correlation between the average waiting time of special transportation users and the space was high. As a result of the analysis of internal degree centrality, the peak time zone is mainly visited by general hospitals, while the off-peak time zone shows high long-term waiting demand for visits by lawmakers. The analysis of external degree centrality showed that residential-based traffic demand was high in both peak and off-peak hours. The results of this study are considered to contribute to the improvement of the quality of the operation of special transportation means, and the academic implications and limitations of the study are also presented.

The purpose of this study is to analyze the effects of a comparative process so that students majoring in urban planning and design can develop the ability to present non-physical alternatives along with the ability to present alternatives to a physical environment to solve urban problems. A total of 30 students majoring in urban planning and urban design were analyzed for their satisfaction with their majors, intention to find a job related to their majors, and academic achievement. This was done after conducting a comparative course of living-lab projects utilizing idle space in a region in connection with a major education course for about a year. For the analysis, the four-group design used by Solomon was used to find the differences between students who participated in the class and those who did not. The analysis showed that the students who participated in the comparative course of the living-lab project were highly satisfied with their major and their intention to find a job related to their major. The results of this study suggest that the process of cultivating the ability to work with local residents and merchants to present physical and non-physical alternatives to solve local problems by utilizing the means of living lab projects has a positive effect on the students' attachment to their majors and their self-esteem.

As a case study, this paper historicizes the film culture in Namchon district in Keijo(京城) based on a preliminary research on the film ephemera produced during the colonial period. Through cross-examining articles appeared in Japanese newspapers and magazines at the time, this paper empirically reconstructs the Japanese settlers' film culture in Keijo, a colonial city whose cultural environment was ethnically divided into 'Bukchon' and 'Namchon.' During the silent era, movie theaters in the Namchon district not only played a role of cinema chain through which films imported and distributed by Japanese film companies were circulated and exhibited but also served as a cultural community for Japanese settlers who migrated to a colony. The film ephemera issued by each theater not only provided information about the movie program, but also connected these Japaneses settlers in colonial city, Keijo to the homogeneous space and time in Japan proper. Both as a minority and colonizer in a colony, these Japanese settlers experienced a sense of 'unity' that could 'distinguish' their ethnic identity differentiated from Koreans through watching movies in this ethnically segregated cultural environment. In doing so, they were also able to connect themselves to their homeland in Japan Proper, despite on a cultural level. This is a cultural practice that strengthens a kind of long distance nationalism. Examining Japanese film culture through film ephemera would not only contribute to the previous scholarship on modern theater culture and spectatorship established since the 2000s, but also be a meaningful attempt to find ways and directions for film history research through non-film materials.

As the use of TBM increases, research has recently increased to to analyze TBM data with machine learning techniques to predict the exchange cycle of disc cutters, and predict the advance rate of TBM. In this study, a regression prediction of disc cutte wear of slurry shield TBM site was made by combining machine learning based on the machine data and the geotechnical data obtained during the excavation. The data were divided into 7:3 for training and testing the prediction of disc cutter wear, and the hyper-parameters are optimized by cross-validated grid-search over a parameter grid. As a result, gradient boosting based on the ensemble model showed good performance with a determination coefficient of 0.852 and a root-mean-square-error of 3.111 and especially excellent results in fit times along with learning performance. Based on the results, it is judged that the suitability of the prediction model using data including mechanical data and geotechnical information is high. In addition, research is needed to increase the diversity of ground conditions and the amount of disc cutter data.

Cyberattacks around the world continue to increase, and their damage extends beyond government facilities and affects civilians. These issues emphasized the importance of developing a system that can identify and detect cyber anomalies early. As above, in order to effectively identify cyber anomalies, several studies have been conducted to learn BGP (Border Gateway Protocol) data through a machine learning model and identify them as anomalies. However, BGP data is unbalanced data in which abnormal data is less than normal data. This causes the model to have a learning biased result, reducing the reliability of the result. In addition, there is a limit in that security personnel cannot recognize the cyber situation as a typical result of machine learning in an actual cyber situation. Therefore, in this paper, we investigate BGP (Border Gateway Protocol) that keeps network records around the world and solve the problem of unbalanced data by using SMOTE. After that, assuming a cyber range situation, an autoencoder classifies cyber anomalies and visualizes the classified data. By learning the pattern of normal data, the performance of classifying abnormal data with 92.4% accuracy was derived, and the auxiliary index also showed 90% performance, ensuring reliability of the results. In addition, it is expected to be able to effectively defend against cyber attacks because it is possible to effectively recognize the situation by visualizing the congested cyber space.
