This study was designed to investigate the characteristics, aesthetics, similarities and differences through the flow of Korean female movies. In order to carry out this study, four movies with representations of each age had to be selected. These four films are respectively Sweet Dream produced during the Japanese colonial period, Madame Freedom which prompted the debate on feminism in the 1950s, The Silver Stallion Will Never Come which combines the devastated lives of women in the 1990s with anti-malevolent views, and A Good Lawyer's Wife which presents a futuristic selection of Korean feminist films. Especially, these works are noteworthy in that they guarantee the typicality and representative of Korean films in each period. Based on this, two common motifs appearing in these works have been intensively studied. One is a 'cage' motif that symbolizes women's detention and the other is a 'mirror' motif that women need to be aware of their situation and check the current situation. Korean women's films have not only shared some of the motifs of 'Cage' and 'Mirror', but also have focused on conveying the author's message that ultimately aimed at linking these motifs.

Smart mirror is an IoT device that attaches a display and an embedded computer to the mirror and provides various information to the user along with the mirror function. This paper presents performance evaluation of the CoMirror system as an extension of the previous research in which proposed and implemented the CoMirror system that connects Smart Mirrors using a network. First, the login performance utilizing face recognition was evaluated. As result of the performance evaluation, it was concluded that the 40 face images are most suitable for face learning and only one face image is most suitable for face recognition for login. Second, as a result of evaluating the message transmission time, the average time was 0.5 seconds for text, 0.63 seconds for audio, and 2.9 seconds for images. Third, as a result of measuring a video communication performance, the average setup time for video communication was 1.8 seconds and the average video reception time was 1.9 seconds. Finally, according to the performance evaluation results, we conclude that the CoMirror system has high practicality.

Currently, the domestic early warning system is issued differently for each disaster, and is operated independently by relevant organizations from central government to local governments. Representative domestic disaster warning systems include disaster broadcasting using CBS(Cell Broadcasting Service) and DMB(Digital Multimedia Broadcasting) Automatic Emergency Alert Service, DITS(Disaster Information Transform System) transmitted and displayed on TV screens, automatic response system, automated rainfall warning system, and disaster message board. However, due to the difference in the method of issuing each emergency alert at the site of an emergency disaster, the alerts are issued at different times for each media, and the delivered content is also not integrated. If these systems are integrated, it is expected that damage to people's property and lives will be minimized by sharing and integrated management of disaster information such as voice, video, and data to comprehensively judge and make decisions about disaster situations. Therefore, in this study, we present a plan for the integration of the disaster warning system along with the analysis of the operation status of the domestic early warning system.

To Republic of Korea in the Indo-Pacific region, the stability and prosperity of the area are directly coupled with national survival, interest. Currently, on account of strategic competition between U.S.A, and China in this area as well as supranational·non-conventional threats, the security environment is unstable, required joint/allied responses. So, lots of states inside(U.S.A., Japan, ASEAN, etc.), also, out of this Indo-Pacific area like EU-NATO, open their own strategy related in Indo-Pacific issues to be involved. R.O.K. government took its own line with publishing self strategy following this international trend, it can be shown korean government's strong intend to join in the pending security issues in this region with 'strategic clarity'. Now, R.O.K. Navy has to back up governments, policy. First, R.O.K. Navy should strengthen the relationship inside and take part in the multilateral cooperation of security. Second, to convey this deterrence message to potential threats, Navy is required to show of forces and have combined exercises. Also, as naval forces of advanced countries, Korea, Navy should be taken action in non-traditional threats, and help developing states improve their sea power. To fulfill this tasks in the wide ocean area, Navy need five inherent characteristics(mobility, flexibility, sustainability, capability of presence and projection). In the end, this paper propose the development plan following operational environment (SWOT) analysis as well.

This paper aims to identify the characteristics implied in the process of change of Stephen Sondheim's musical style and to derive the structural communication tools that connect the creator and audience and the implications. The strategies that appear in Sondheim's musical works are the following. First, Sondheim's early musical works follow the principles of book musical and emphasize the integration faithful to the basic elements such as the rhythm and meaning of the lyrics. Second, in the era of early postmodernism, Sondheim attempts the principle of extreme deconstruction through the concept musical Company and pursues rational thought through fragmented dramatic flow. Third, while maintaining dramatic linearity to overcome the lack of immersion caused by extreme deconstruction, Sondheim realizes a more elaborate and formalized fusion style of the principles of integration and deconstruction through the choruses and the songs of the characters in Little Night Music and Sweeney Todd. Finally, Sondheim attempts multiple experiments to break down the boundaries of act and scene and to express new subject matters through his works such as Sunday Park with George and Into the Woods. In conclusion, Sondheim's fusion experiments and strategies are the process of finding a framework and a medium of communication to induce dramatic immersion of audience and at the same time create rational thinking about social problems to deliver the message of the creative work with the leading aesthetics of the modern musical's box-office success.

This study examined how the explicit and implicit race attitudes differ according to age and gender from the developmental perspective in Korean elementary students. The study also investigated the efficacy of a multi-cultural education program on explicit and implicit attitude change in elementary school students. This thesis consists of two parts. In Study 1, elementary school students(first grade:117, fourth grade:117) completed Explicit Attitudes Rating Scales, Explicit Preference Test, and Child Implicit Association Tests (Korean-White/Korean-Black/ Korean-Southeast Asian IATs). The effects of age and gender on explicit and implicit attitudes toward Korean/White/Black/Southeast Asian were examined with two-way MANOVA. The results demonstrated that as age increases, in-group preference/out-group bias decrease on the explicit level. In contrast, on the implicit level, as age increases, in-group preference/out-group bias do not decrease. Rather, prejudiced attitudes toward blacks increase. Study 2 was performed to investigate the effect of a multi-cultural education program on explicit and implicit attitude change toward races in elementary school students. The program conveying an anti-bias message consists of three sessions, and the procedures are as follows; watching video clips, confirming contents and short discussion. Two classes in the program and two classes in comparative groups on the first and fourth grade of elementary school were assessed. The results showed that black preference significantly increased both in the first and the fourth grade elementary students on the explicit attitude level, but not on the implicit level. The theoretical and practical implications of these findings were discussed.

The objective of this study is to derive the appropriate perception location for changes in driving behavior of autonomous vehicles in urban road environments based on traffic safety signs. For this purpose, 32 types of signs that induce changes in driving behavior were selected from currently used traffic safety signs and classified as three types according to changes in driving behavior. Based on this, three scenarios were designed: stop, speed change, and lane change scenarios. These were used to confirm the impact on traffic flow. As a result of the analysis, it was found that each scenario needs to receive information on traffic safety signs in advance to ensure changes in traffic flow and safety. Consequently, the appropriate perception location can be used as a basis for establishing standards for delivering message sets to autonomous vehicles or revising traffic safety signs for them. In addition, this study is expected to contribute to the establishment of safe and efficient driving strategies on urban roads as autonomous vehicles are introduced in the future.

This study investigated the relationship between emotional contagion and altruistic behaviors and also examined the moderating effect of self-construals(independent and interdependent self) in this relationship. It was hypothesized that the emotional expression of people in need would be caught by others through automatic mimicry, that emotional information would be internalized through the facial-feedback process and that the transferred emotion would eventually result in a motive to call for altruistic behaviors. In Study 1, participants watched a video clip about a disabled student reporting difficulties in school life but showing facial expression opposite to the contents of message to separate emotional contagion and empathy. Participants' decision to participate in voluntary works for the disabled student was measured. As a result, it was found that the more participants experienced emotional contagion, the more they participated in altruistic behaviors. Study 2 measured the vulnerability to emotional contagion, actual experiences of altruistic behaviors, and self-construals. The results of hierarchical regression showed that interdependent self moderated the influence of emotional contagion on altruistic behaviors whereas independent self moderated the relationship in an opposite direction. The implications of emotion and altruistic behaviors in human evolution process are discussed.

In the reality that the fishing population is decreasing and the single-man fishing vessels is increasing, mandatory equipment for navigation and radio equipments for the safety of fishing boats has continued to be added. Therefore, many equipment such as navigation, communication and fishing are installed in the narrow steering room, so it is very confusing and a number of monitors are placed in the front, which is a factor that degrades the function of maritime observation. To solve this problem, we studied an interface that integrates and operates to major radio facilities such as very high frequency-digital selective calling equipment (VHF-DSC), automatic identification system (AIS) and fishing boat location transmission device (V-pass) into one multi function display (MFD) based on LAN. In addition, IEC61162-450 UDP packets and IEC61162 sentence were applied to exchange data through link between MFD and radio equipments, and additional messages needed for each equipment and function were defined. The integrated MFD monitor is easily operated by the menu method, and the performance of the interface was evaluated by checking the distress and emergency communication functions related to maritime safety and the message transmission status by equipment.

This study conducted a digital forensic analysis of Signal and Telegram, two secure messengers widely used in the Android environment. As mobile messengers currently play an important role in daily life, data management and security within these apps have become very important issues. Signal and Telegram, among others, are secure messengers that are highly reliable among users, and they safely protect users' personal information based on encryption technology. However, much research is still needed on how to analyze these encrypted data. In order to solve these problems, in this study, an in-depth analysis was conducted on the message encryption of Signal and Telegram and the database structure and encryption method in Android devices. In the case of Signal, we were able to successfully decrypt encrypted messages that are difficult to access from the outside due to complex algorithms and confirm the contents. In addition, the database structure of the two messenger apps was analyzed in detail and the information was organized into a folder structure and file format that could be used at any time. It is expected that more accurate and detailed digital forensic analysis will be possible in the future by applying more advanced technology and methodology based on the analyzed information. It is expected that this research will help increase understanding of secure messengers such as Signal and Telegram, which will open up possibilities for use in various aspects such as personal information protection and crime prevention.
