The color gray in the cinema expresses the private or public memory and oblivion in the reminiscence scenes. The aesthetic function and meaning of gray that interacts with other elements in cinematic time and space are expanded in various ways. This study was analyzed the cases in which gray was used as the main visual style by limiting the scope to Korean films. Based on the traditional cultural symbolic meaning of gray, I analyzed how it was applied and transformed in films, and interpreted the cultural-social meaning by the interaction between gray and other elements. In film history starting from monochrome, gray has been used as a visual device suitable for realizing cinematic or imaginary reality. Gray is adopted when dreams or recollections are visualized as imaginary reality, and it is used when dreamy imaginations of daydreaming are demonstrated. Gray, which reproduces the dreamlike reality of imagination, is the concrete and realistic way of expression. First, in Korean films, gray is a flashback visual device that recalls the past, and is an intermediary visual form that materializes the imaginary. In films such as Ode to My Father (2014), DongJu (2015), A Resistance(2019) and The Battle : Roar to Victory (2019), the gray of the past is a visual device for cultural memory that builds the homogeneity and identity of the group. In the era of hyper-visibility, gray in black and white images is intended to be clearly remembered by unfamiliarity rather than blurry oblivion by familiarity. Second, in genre films with disaster materials such as Train To Busan (2016) and Ashfall (2019), the grays of rain, fog, clouds, shadows and smoke highlight other elements, and the gray color causes anxiety and fear. In war films such as TaeGukGi: Brotherhood Of War (2003) and The Front Line (2011), gray shows a more intense brutality than the primary color. In sports films such as 4th Place (2015), Take Off (2009) and Forever The Moment (2007), gray expresses uncertainty and immaturity. Third, gray visualizes the historical memory of A Petal (1996), the oblivion in Oh! My Gran (2020) and Poetry (2010), and the reality of daydreaming Gagman (1988) and Dream (1990). At the boundary between imagination and reality, gray is a visual form of dreams, memories and forgetfulness.

Linking Ukraine's education system with the trends of global digitalization is mandatory to ensure the sustainable, long-term development of the country, as well as to increase the sustainability of the education system and the economy as a whole during the crisis period. Now the main problems of the education system in Ukraine are manifested in a complex context caused by Russian armed aggression. In the context of war, problems include differences in adaptation to online learning among educational institutions, limited access to education for vulnerable groups in the zone of active hostilities, the lack of digital educational resources suitable for online learning, and the lack of basic digital skills and competencies among students and teachers necessary to properly conduct online classes. Some of the problems of online learning were solved in the pandemic, but in the context of war Ukrainian society needs a new vision of education and continuous efforts of all social structures in the public and private environment. In the context of war, concerted action is needed to keep education on track and restore it in active zones, adapting to the needs of a dynamic society and an increasingly digitized economy. Among the urgent needs of the education system are a change in the teaching-learning paradigm, which is based on content presentation, memorization, and reproduction, and the adoption of a new, hybrid educational model that will encourage the development of necessary skills and abilities for students and learners in a digitized society and enable citizens close to war zones to learn.

Background: Nowadays, dental health problems in Indonesia are still quite high. It is one of which influenced by low public awareness of the importance of maintaining the health of teeth and mouth that can be measured by toothbrushing behavior. Based on the results of RISKESDAS 2018, only 2.8 percent of the population has a proper toothbrushing behavior. Behavior tends to form at age 6 to 12 years. At this age, children begin to develop habits that tend to settle until adulthood, including toothbrushing behavior. Social cognitive theory is a theory of behavioral change that explains that behavioral changes are influenced by the environment, personal, behavior where these three factors influence each other. This study aims to identify changes in the dental behavior of second grades students before and after the joint toothbrushing at school for 21 days. Methods: A pre-experimental study-design was conducted on elementary school by pre-post treatment method where there are 2 classes that get intervention and 2 other classes as control. A joint toothbrush is performed every morning before the school activities begin. Before and after the joint toothbrushing, all classes are given questionnaires to see if there are any changes in behavior seen through knowledge, attitudes, and practice. Results: Respondent group showed increasement on their knowledge, attitudes, and behaviors towards toothbrushing. In contrast, the control groups showed no significant differences in the 3 factors. Conclusion: In this study the education of toothbrushing through environmental changes is quite effective in elementary school children. Insights into the benefits of this program and refinements of optimally targeted intervention, including longitudinal studies are needed to improve the results.

This study was conducted to develop the unique native local foods of Namwon and to provide basic data needed to reinvigoratethe tourist industry and local economy. Perception and satisfaction with native local foods of Namwon were surveyed in 483 tourists (246 men and 237 women 53% visiting Namwon for the first time). Of the participants, 41.2% did not stay or eat in Namwon. Most tourists visited with other family members and spent approximately 20,000 won per capita on food. Of the foods sampled for the first time, preferred foods were (in order of preference and intention to order again) Chueo-tang, Hanjeongsik, wild edible greens-jeongsik, and black pork. The degree of food satisfaction was relatively favorable (3.54${\pm}$0.08 points on a 5-point satisfaction scale), with taste being the most important factor affecting the degree of satisfaction for 92.9% of the subjects. However, willingness to revisit Namwon on the basis of the local foods was not as high as the degree of satisfaction with the foods. Insufficient information and publicity concerning Namwon local foods were cited as impediments, and suggested improvements included taste, sanitation and food-based tourism. The degree of satisfaction was higher in men than in women. Age, residence, and occupation were not related to the degree of satisfaction. But, the willingness to revisit Namwon to sample local foods was related with gender (men more willing) and occupation (public service personnel, business owners, salaried employees, professionals, and housewives more willing, in order). Women in general and housewives in particular were most critical in food assessment.

This study was conducted to examine the superior factors and the perception of Korean traditional foods by college students studying in food related industries. The subject group consisted of 65.0% of the students majoring in food service & culinary arts, 12.9% of the students majoring in food & nutrition, and 7.3% of the students majoring in baking & pastry. The nutritional value was evaluated as the top superior factor of Korean traditional foods by the study subjects. In addition, 92.4% of reported that they had eaten Korean traditional foods in the past, 76.8% of whom responded that the reason for having Korean traditional foods was its time-honored tradition. 'Cooking for oneself' was considered to be the most popular way (78.2%) of obtaining Korean traditional foods, while the traditional market (58.6%) was the most popular place to purchase the foods. 'Not having enough time' (47.2%) was the primary reason for not having Korean traditional foods, although 72.9% of the subjects reported that they wanted to learn about Korean foods. 'Standardization of taste, nutritional value, and recipes' was found to be the most important factor (41.3%) required to increase the consumption of Korean traditional foods. Additionally, 56.1% of the subjects responded that they feel there is a need for modernization of the cuisine to meet the taste of the general public. However, 61.4% of the subjects responded that the succession of traditional dietary culture was the primary reason for developing traditional cuisine, which indicates that there is a bright future for Korean traditional foods.
