A fast image encryption system based on substitution and diffusion was proposed, which includes one covering process, one substitution process and two diffusion processes. At first, Chen's chaotic system together with an external 256-bit long secret key was used to generate the key streams for image encryption, in which the initial values of Chen's chaotic system were regarded as the public key. Then the plain image was masked by the covering process. After that the resulting image was substituted with the disturbed S-Box of AES. Finally, the substituted image was diffused twice with the add-modulo operations as the core to obtain the cipher image. Simulation analysis and comparison results with AES and some existing image cryptosystems show that the proposed image cryptosystem possesses the merits of fast encryption/decryption speed, good statistical characteristics, strong sensitivity and etc., and can be used as a candidate system of network security communication.

As the share of leisure culture increases these days, expectations are rising for the high quality of culture while increasing interest in leisure and tourism. The percentage of the population going on weekend trips to broaden the horizons of elementary, middle and high school students has continued to rise in proportion to the expectations for cultural enjoyment. We expect that visitors' weekend family activities will include relaxing, playing and educational purposes. Recent educational programs have moved from the past where only children were allowed to be onsite, to a shared style in which parents can engage in educational activities, potentially leading to the implicit involvement of family ties and family elasticity. The effects of education are not expressed by the period that ends in a single moment of experience, but by the continuity of training and experience. The same holds true for family affinity, communication and empathy. Providing opportunities for family experience and education is a national responsibility for broken family and restoring solidarity with the growing number of single-person households. Furthermore, it is a duty of museums and galleries today, and it is necessary to come up with methods to enhance family solidarity and family affinity. In particular, it is imperative to develop and provide educational programs for educational purposes at the Education Museum, and to develop " education for family " at the social level. This paper aims to analyze the results of all family participating education programs provided by family education programs at the Education Museum through family surveys and interviews, and to enhance the activation of family types education programs more actively.

The purpose of this study were to develop PBL(problem-based learning) program, and to examine the effects of PBL. This paper applied PBL to a "Culture of Clothing" class, comprised of 23 undergraduate students majoring in Home Economics. As part of the PBL curriculum, the class assigned students to design and create brochures about the culture of clothing by going on field trips to the National Folk Museum of Korea. The class met for five weeks, 3 hours per week. The effectiveness of PBL was measured based on the students' self-reflective journals, self-assessments, and satisfaction surveys. The study gathered three major feedbacks from the students after taking the PBL class. First, the students recognized the importance of cooperation and communication in problem-solving process. Second, the students appreciated that students themselves were implementing the self-directed learning. Third, the students were satisfied with the overall quality of the PBL class, based on their feedbacks and surveys. However, the students' self-assessments show their acknowledgement of the lack of creativity and critical-thinking skills. The study also observed relatively low-satisfaction ratings about the learning environment at the National Folk Museum of Korea.

The purpose of this study is to derive interaction types that appear variously in immersive contents through John Dewey's empirical theory, and to explore how the derived types are delivered in real cases. For this reason, two cases of the National Museum of Korea 'Immersive Digital Gallery' and 'Arte Museum Jeju' were analyzed through interaction types derived from the empirical theory. The interaction types derived based on the experience theory are the elements of 'multi-sensory', 'simultaneous experience' and 'sensory expansion'. In both cases, these types appear connected rather than grafted one by one in common. In one direction, 'multi-sensory' leads to 'sensory expansion', and in two directions, 'simultaneous experience' leads to 'sensory expansion'. As such, the core types of communication between technology and humans are not delivered one by one, but a cycle of interaction is formed in multiple ways. Therefore, it can be seen that the interaction type of immersive contents is expanded step by step by fusion of various senses and experiences in various fields, rather than a 1:1 partial delivery method. Based on this, it will be necessary to study how types are expanded and how viewers are affected when interaction is implemented in immersive contents in the future.

Purpose This study investigated the impact of review language style (affective vs. cognitive) on review helpfulness and the moderating effects of the types of attractions in the relationships between the review language and its helpfulness. Design/methodology/approach This study investigates the impact of review language style (affective vs. cognitive) on review helpfulness and the moderating effects of the types of attractions in the relationships between the review language and its helpfulness. This study selected two hedonic and utilitarian attractions (Hedonic: Brandenburg Gate, Utilitarian: Peragamon Museum) located in Berlin. A total of 3,320 reviews was collected from TripAdvisor. We divided online reviews posted for these places into reviews with more affective language and with more cognitive language by using the LIWC. Then, we investigated the impact of language effect on review helpfulness across the attraction type. Findings The findings suggest that peers tend to judge more helpful toward cognitive language in attraction reviews regardless of attraction type. This study found that peers tend to perceive more helpful toward cognitive review in utilitarian attractions. Even though there was an interaction effect between review language and attraction type, in hedonic attractions, the influence of cognitive language was reduced, but still cognitive reviews would get more helpful votes.

Dunhuang murals are one of the most outstanding achievements in the art of traditional grotto painting in China, and are known as a "Wall Museum". As a representative of the heyday of Dunhuang murals, an in-depth exploration of Dunhuang murals from the perspective of color will help researchers understand the laws and connotations of color in Dunhuang murals during the Tang Dynasty and fully grasp the art of Dunhuang murals. The color system of the traditional Chinese "Five colors" concept expresses the cultural attributes and emotions of the Chinese people and has distinctive national characteristics. This thesis provides a theoretical grasp of the traditional Chinese "Five colors" view of color system, the Dunhuang murals of the Tang Dynasty, and the color configuration of the color composition principles, and uses the modern design principles of color composition to conduct an in-depth analysis of the configuration of the Dunhuang murals' use of color. Explore the unique characteristics of Tang Dynasty Dunhuang murals, and help modern designers master richer color application techniques by learning from and studying the harmonious patterns of Dunhuang murals to provide a new path for the dissemination of excellent Chinese traditional culture.
