This study aimed to suggest ways to utilize local governments' SNS by recognizing whether advertising affinity affects advertising effectiveness and significant differences between photo types (personality or absence) and generation. The survey was conducted from 1 April to 16 April 2021, and a total of 235 copies were used for empirical analysis. According to the analysis, advertising likeability affects advertising effects, and photos involving tourists have a greater impact on advertising effects in their 20s. This will require local governments to make various efforts to identify the generations that access SNS the most, and to encourage them to post photos suitable for that generation, along with ensuring that tourists' photos are posted at tourist attractions.

After liberation from Japanese colonial rule in 1945, there was the three-year period of United States Army Military Government in Korea. In 1948, Democratic People's Republic of Korea, and Republic of Korea were established in the north and south of the Korean Peninsula. The Republic of Korea is now a modern state set in the southern part of the Korean. We usually refer to Koreans as people who belong to the Republic of Korea. Can we say that is true exactly? Why make of this an obsolete question? The period from 1945 when Korea was emancipated from Japanese colonial rule to 1948 when the Republic of Korea was established has not been a focus of modern Korean history. This three years remains empty in Korean history and makes the concept of 'Korean' we usually consider ambiguous, and prompts careful attention to the silence of 'some Koreans' forced to live against their will in the blurred boundaries between nation and people. This dissertation regards 'Koreans' who came to live in the border of nations, especially 'Korean-Japanese third generation women artists'who are marginalized both Japan and Korea. It questions the category of 'Korean women's art' that has so far been considered, based on the concept of territory, and presents a new perspective for viewing 'Korean women's art'. Almost no study on Korean-Japanese women's art has been conducted, based on research on Korean diaspora, and no systematic historical records exist. Even data-collection is limited due to the political situation of South and North in confrontation. Representation of the Mother Country on the Artworks by First and Second-Generation Korean-Japanese(Zainich) Women Artists after Liberation since 1945 was published in 2011 is the only dissertation in which Korean-Japanese women artists, and early artistic activities. That research is based on press releases and interviews obtained through Japan. This thesis concentrates on the world of Korean-Japanese third generation women artists such as Kim Jung-sook, Kim Ae-soon, and Han Sung-nam, permanent residents in Japan who still have Korean nationality. The three Korean-Japanese third generation women artists whose art world is reviewed in this thesis would like to reveal their voices as minorities in Japan and Korea, resisting power and the universal concepts of nation, people and identity. Questioning the general notions of 'Korean women' and 'Korean women's art'considered within the Korean Peninsula, they explore their identity as Korean women outside the Korean territory from a post-territorial perspective and have a new understanding of the minority's diversity and difference through their eyes as marginal women living outside the mainstream of Korean and Japanese society. This is associated with recent post-colonial critical viewpoints reconsidering myths of universalism and transcendental aesthetic measures. In the 1980s and 1990s art museums and galleries in New York tried a critical shift in aesthetic discourse on contemporary art history, analyzed how power relationships among such elements as gender, sexuality, race, nationalism. Ghost of Ethnicity: Rethinking Art Discourses of the 1940s and 1980s by Lisa Bloom is an obvious presentation about the post-colonial discourse. Lisa Bloom rethinks the diversity of race, ethnicity, sexuality, and gender each artist and critic has, she began a new discussion on artists who were anti-establishment artists alienated by mainstream society. As migration rapidly increased through globalism lead by the United States the aspects of diaspora experience emerges as critical issues in interpreting contemporary culture. As a new concept of art with hybrid cultural backgrounds exists, each artist's cultural identity and specificity should be viewed and interpreted in a sociopolitical context. A criticism started considering the distinct characteristics of each individual's historical experience and cultural identity, and paying attention to experience of the third world artist, especially women artists, confronting the power of modernist discourses from a perspective of the white male subject. Considering recent international contemporary art, the Korean-Japanese third generation women artists who clarify their cultural identity as minority living in the border between Korea and Japan may present a new direction for contemporary Korean art. Their art world derives from their diaspora experience on colonial trauma historically. Their works made us to see that it is also associated with postcolonial critical perspective in the recent contemporary art stream. And it reminds us of rethinking the diversity of the minority living outside mainstream society. Thus, this should be considered as one of the features in the context of Korean women's art.

This study is a study on the YouTube e-learning advanced service plan in the non-face-to-face era. The trends in education change were examined through literature research and prior research, and improvement measures were suggested through online surveys and in-depth interviews. As for the research method, the first online survey was conducted based on the Honeycomb model and the Likert 5-point scale targeting 90 MZ generation who have experience learning on YouTube for a total of 14 days from October 15 to 28, 2021. A second in-depth interview was conducted with 6 people who answered that the frequency of learning through YouTube is high. As a result of the experiment, users thought that there was an improvement point according to the purpose of learning, and they were able to derive elements that felt a problem in common. In addition, I proposed a new YouTube learning platform through additional questions. Through this study, it is expected that YouTube e-learning service reference materials can be used to respond to the post-non-face-to-face era.

In this paper a K-band harmonic oscillator competitive to ordinary Push-Push type oscillators is introduced. This oscillator is composed of two-X-band dielectric resonance circuits. To favor its harmonic generation, the load effect and the bias effect are studied to allow the maximum harmonic distortion. As results, the dielectric resonated load and the class A bias are used for the 2nd harmonic generation. analytical study for modelling of voltage controlled dielectric resonator is carried out with theoretical background. The performance of the circuit is evaluated by simulation using harmonic balanced method. The novel structure has ont only a voltage tuning circuit but also an output port at fundamental frequency as the function of prescaler for phase lockede loop application on the just single oscillation structure. In experimentation, the output freqneyc of the 2nd harmonic signal is 20.5GHz and the maximum power level of output is +5.5dBm without additional post amplifiers. the harmonic oscillator exhibits -30dBc of high fundamental frequency rejection without added extra filters. The phase noise of -90dBc/Hz at 100kHz off-carrier has been achieved under free running condition, that satisfies phase noise requirement of IESS 308. The proposed oscillator may be utilized as the clean and stable fixed local oscillator in Transmit Block Upconvertor(TBU) or Low oise Block downconvertor(LNB) for K/Ka-band digital communications and satellite broadcastings.

This study is to develop digital leadership in a field of national defense. Today, korean society is facing the crisis of national security. But national defense leadership is not show in the circumstance of national security crisis. As you know, national defense leadership is a process that make use of influence. Which means it converges people's interest and demands well and also show people the right vision of national defense and make them to comply the policy about national security. Because of the environmental change, our national defense leadership is having a new turning point. First, international order, which is under post-cold war, raises possibility of guarantee of peace and security in international society but also, cause the increase of multiple uncertainty and small size troubles in security circumstance. In addition, Korean society is rushing into democratization and localization period by success in peaceful change of political power went through about three times. The issue of political neutralization of military is stepping into settlement but still, negative inheritance of old military regime is worrying about it. In this situation, we can't expect rise in estimation about the importance of security and military's reason for being. So, military have to give their concern to not only internal maintenance of order and control and growth of soldiers but also developing external leadership to strength influence to society and military's the reason for being. So for these alternative I'm suggesting a digital leadership of national defense which fits digital era. This digital leadership is the leadership which can accept and understand digital technology and lead the digital organization. To construct digital national defense we need a practical leadership. The leadership has to be digital leadership with digital competence that can direct vision of digital national defense and carry out the policy. A leader who ha s digital leadership can lead the digital society. The ultimate key to construct digital government, digital corporate and digital citizen depends on digital leader with digital mind. To be more specific, digital leadership has network leadership, next generation leadership, knowledge driven management leadership, innovation oriented leadership. A leader with this kind of leadership is the real person with digital leadership. From now on, to rise this, we have to build up human resource development strategy and develop educational training program.

In this paper, we propose a method to automatically generate a configured song with melodies composed of front/middle/last parts by using hierarchical artificial neural networks in automatic composition. In the first layer, an artificial neural network is used to learn an existing song or a random melody and outputs a song after performing rhythm post-processing. In the second layer, the melody created by the artificial neural network in the first layer is learned by three artificial neural networks of front/middle/last parts in the second layer in order to make a configured song. In the artificial neural network of the second layer, we applied a method to generate repeatability using measure identity in order to make song with repeatability and after that the song is completed after rhythm, chord, tonality post-processing. It was confirmed from experiments that our proposed method produced configured songs well.

Today, the computing environments is very complex, so researches that endow a system with the self-healing's ability that recognizes problem arising in a target system are being an important issues. However, the existing methodology, the goal for the new requirements for self-healing system developers to model and analyze the constraints that must be greater efforts. Therefore, in this paper are aware of problems detected by the system to solve the problem is the analysis of goal-based scenarios. In addition, there is a pre and post applying a strategy to be dynamically reconfigured to show you how to self-healing. These proposed new requirements for methodology, self-healing reduces the load on the developer's analysis.

Intelligent schemes for an automatic generation of DEM (digital elevation model) are implemented. The need for these post-processing schemes is that interpolation alone produces severe blunders, however sophisticated it is. These blunders occur most seriously along the boundaries of a scene, over rivers, and along the coast. Even a state-of-the-art commercial software retains such blunders. The intelligent schemes implemented are (1) center-of-gravity and empty-center-index which quantify how evenly distributed interpolants are within in interpolation radius. (2) a segmentation scheme to discern whether or not an empty segment in stereo-match results should be interpolated, and (3) a segmentation scheme for removing noise-like features, with these methods, in the final DEM, identical coastline and river region to those in the original SPOT scenes are achieved. The DEM exhibits substantial improvements over the products of an existing commercial software.

We aim to reinterpret Bong Joon-ho's Snowpiercer through theory of posthumanism. Posthuman is a compound word of 'post' and 'human', which means transcendent-man. However, we would like to extend the meaning of posthuman or cyborgs as not only to "new human figure, or transcendent-man" but as to "human living in a digital age of converged technology". Through the extension of the meaning of posthuman, we would be able to not only find posthuman in Science Fiction movies but also apply it to our real world. Also, through the extended meaning, we will reinterpret all the elements from the film as cyberspace and as posthuman or cyborgs. Moreover, through examination of these "cyborg figures" in Bong Joon-ho's Snowpiercer (2013), we argue that the film is criticizing posthumanism in the reality that these days, people are losing the humanity due to the combination with the machine. It seems that he claims of the collapse of the current system, suggesting new human generation as the solution.
