The objective of this study was to evaluate how wives of alcoholics could escape from the co-dependency relationship and recover their ego-subjectivity. This study conducted 1:1 in-depth interviews with five wives of alcoholics in order to achieve the study objective. Data collected from the interviews were analyzed by the phenomenological method proposed by Giorgi[1]. First, researchers extracted five subjects, including 'Co-dependency (Loss of ego-identity)', 'Impoverished life', Ego-prop', Ego-awareness', and 'Ego-subjectivity recovery' in the course of the data analysis. Secondly, researchers identified "Ego-subjectivity recovery through Ego-awareness of a wife of an alcoholic", an essential theme, by integrating all subjects. Researchers, based on the analysis results, proposed practical alternatives for various psychological treatment system and ego-prop like as counselling, family member of alcoholic wives and power of faith.

Over the past few decades, gender equality has been considered one of the fundamental principles and a significant crosscutting issue in international development. However, beyond applying 'gender equality' as a policy buzzword, there has been a lack of critical reviews on how generally 'gender equality in education' is understood and constructed in Korea's development programs and projects. In this regard, this paper explores the use of vocabularies and semantic meanings of gender equality in the Korean Government's Academic Cooperation Program and its 52 projects. By applying mixed contents analysis as a method, the research resulted in several findings: first, the policy papers recently highlighted Korea's directions on gender mainstreaming and gender-sensitive approaches in international development. Second, 'integrating women and girls' into education institutions was emphasized in various projects; third, the term women rather than gender were used in the texts, highlighting their position as a 'marginalized group.' Lastly, there was a lack of evidence of projects dealing with changing gender-based power relations. The constructed gendered relations and powers were identified throughout projects, usually acting as barriers to project activities. However, they were only identified, not challenged, by the program. In conclusion, whilst Korean international development and educational development discourse actively embrace Women in Development (WID) and Gender and Development (GAD) in their programs, it is time to consider the issue of gender equality from different standpoints, such as identity, rights, and capabilities and a more active engagement with Korea's domestic issues in gender discourse and practices is also needed.

The recent decline in the school-age population has led to a more conservative and conservative approach to the establishment of schools. In the judgment of school establishment, it is required to make a decision method that can make objective and comprehensive judgment of various situations rather than local analysis of a single school. In this changing situation, EduFine system and placement establishment system were introduced to comprehensively analyze the feasibility of student placement and school establishment. However, the EduFine system of the Ministry of Education has few users because it is difficult to use education and it is difficult for users to use. Based on the GIS, the placement establishment system was able to analyze the number of students and the status of apartment buildings in a comprehensive manner. But placement establishment system has been used mainly in support of investment assessment rather than research. Therefore, there is a need to increase the utilization of users by linking two systems or integrating them into one system. In this study, we want to derive the functions to improve the GIS - based layout establishment system through user analysis such as comparative analysis and survey of existing systems. In particular, the purpose of the study is to improve the function of system, to improve the students' placement ability and the school establishment work ability and to improve the user satisfaction.

This study is a review study attempted to analyze the current situation of surgical robots based on previous research on surgical robots in the era of the 4th revolution, and to forecast the future direction of surgical robots. Surgical robots have made full progress since the launch of the da Vinci and the surgical robot is playing a role of supporting the surgeries of the surgeons or the master-slave method reflecting the intention of the surgeons. Recently, technologies are being developed to combine artificial intelligence and big data with surgical robots, and to commercialize a universal platform rather than a platform dedicated to surgery. Moreover, technologies for automating surgical robots are being developed by generating 3D image data based on diagnostic image data, providing real-time images, and integrating image data into one system. For the development of surgical robots, cooperation with clinicians and engineers, safety management of surgical robot, and institutional support for the use of surgical robots will be required.

Band parameters and superconductivity of yttrium hypocarbide ($Y_2C$) have been investigated. The computations are performed using first-principles pseudopotential method within a generalized gradient approximation. The equilibrium lattice parameters have been determined and compared with experiment. Moreover, the material of interest is found to be stiffer for strains along the a-axis than those along the c-axis. A band-structure analysis of $Y_2C$ implied that the latter has a metallic character. The examination of Eliashberg Spectral Function indicates that Y-related phonon modes as well as C-related phonon modes are considerably involved in the progress of scattering of electrons. By integrating this function, the value of the average electron-phonon coupling parameter (${\lambda}$) is found to be 0.362 suggesting thus that $Y_2C$ is a weak coupling Bardeen-Copper-Schrieffer superconductor. The use of a reasonable value for the effective Coulomb repulsion parameter (${\mu}^*=0.10$) yielded a superconducting critical temperature $T_c$ of 0.59 K which is comparable with a previous theoretical value of 0.33 K. Upon compression (at pressure of 10 GPa) ${\lambda}$ and $T_c$ are increased to be 0.366 and 0.89 K, respectively, showing thus the pressure effect on the superconductivity in $Y_2C$. The spin-polarization calculations showed that the difference in the total energy between the magnetic and non-magnetic $Y_2C$ is weak.

As a large quantity of information is presented in XML format on the web, there are increasing demands for XML security. Research area or n security is about Encryption Digital signature, Key management and Access control. until now research on U security has been focused on the security of data network using digital signature and encryption technology. As XML data become extensive and complex XML security comes to involve not only network security but also managerial security. Managerial security is guaranteed through access control. But XML Encryption supports simple network security. So it can't support multiple users and multiple access control policies. In this paper, we propose an integration method of encryption and access control policy for securing XML documents. This methodology can supper multiple authorizations of multiple users with integrating access control. And this can reduce the cost of evaluation process of the existing complicated access authorization with pre-processing.

The graph-based tag recommendation algorithm FolkRank can effectively utilize the relationships between three entities, namely users, items and tags, and achieve better tag recommendation performance. However, FolkRank does not consider the internal relationships of user-user, item-item and tag-tag. This leads to the failure of FolkRank to effectively map the tagging behavior which contains user neighbors and item neighbors to a tripartite graph. For item-item relationships, we can dig out items that are very similar to the target item, even though the target item may not have a strong connection to these similar items in the user-item-tag graph of FolkRank. Hence this paper proposes an improved FolkRank algorithm named FolkRank++, which fully considers the user-user and item-item internal relationships in tag recommendation by adding the correlation information between users or items. Based on the traditional FolkRank algorithm, an initial weight is also given to target user and target item's neighbors to supply the user-user and item-item relationships. The above work is mainly completed from two aspects: (1) Finding items similar to target item according to the attribute information, and obtaining similar users of the target user according to the history behavior of the user tagging items. (2) Calculating the weighted degree of items and users to evaluate their importance, then assigning initial weights to similar items and users. Experimental results show that this method has better recommendation performance.

Purpose Cyber deviance of adolescents has become a serious social problem. With a widespread use of smartphones, incidents of cyber deviance have increased in Korea and both quantitative and qualitative damages such as suicide and depression are increasing. Research has been conducted to understand diverse factors that explain adolescents' delinquency in cyber space. However, most previous studies have focused on a single theory or perspective. Therefore, this study aims to comprehensively analyze motivations of juvenile cyber deviance and to develop a predictive model for delinquent adolescents by integrating four different theories on cyber deviance. Design/methodology/approach By using data from Korean Children & Youth Panel Survey 2010, this study extracts 27 potential factors for cyber deivance based on four background theories including general strain, social learning, social bonding, and routine activity theories. Then this study employs econometric analysis to empirically assess the impact of potential factors and utilizes a machine learning approach to predict the likelihood of cyber deviance by adolescents. Findings This study found that general strain factors as well as social learning factors have positive effects on cyber deviance. Routine activity-related factors such as real-life delinquent behaviors and online activities also positively influence the likelihood of cyber diviance. On the other hand, social bonding factors such as community commitment and attachment to community lessen the likelihood of cyber deviance while social factors related to school activities are found to have positive impacts on cyber deviance. This study also found a predictive model using a deep learning algorithm indicates the highest prediction performance. This study contributes to the prevention of cyber deviance of teenagers in practice by understanding motivations for adolescents' delinquency and predicting potential cyber deviants.

The operation method of offline venues such as local festivals usually has problems such as the absence of real-time events and booth information, wasting time in the process of purchasing and receiving goods, and stagnating the movement of guests. This study increases the convenience of guests and managers by integrating all contents in the venue in the form of booth, thereby increasing the uniformity of event information and the efficiency of booth operation. In addition, a system was designed to minimize movement problems and improve performance by detecting the movement of guests within the venue and increasing the efficiency of arranging booths based on location data. It has been developed as a low-cost system that measures wireless packets with portable wireless LAN APs and control units. This has advantages in the operation of the venue, which consists of the installation and dismantling of variable booths in a short period of time. It is expected that the integrated operation of the venue will be utilized by linking the movement data of guests to activate visits and increase sales through data-based promotions.
