  • Since regulations of exhaust emissions are continuously reinforced, studies to reduce harmful emissions during the cold start period of SI engines have been carried out very extensively worldwide. During the cold start period, raising the temperature of cold exhaust gas is a key strategy to minimize the light-off time of three way catalysts. In this study, a synthetic gas containing a large amount of hydrogen was injected into the exhaust manifold to raise the exhaust gas temperature and to reduce harmful emissions. The authors tried to evaluate changes in exhaust gas temperature and harmful emissions through controlling the engine operating parameters such as ignition timings and lambda values. Also the authors investigated both combustion stability and reduction of harmful emissions. Experimental results showed that combustion of the synthetic gas in the exhaust manifold is a very effective way for solving the problems of harmful emissions and light-off time. The results also showed that the strategy of retarded ignition timings and increased air/fuel ratios with ESGI is effective in raising exhaust gas temperature and reducing harmful emissions. Futhermore, the results showed that engine operating parameters ought to be controlled to lambda = 1.2 and ignition timing = $0{\sim}3^{\circ}$ conditions to reduce harmful emissions effectively under stable combustion conditions.

  • Many festivals are based on overseas municipalities 'city image marketing' planning. This trend is gradually reflected in this country as with the Kimcheon International Family Theatre Festival in the Republic of Korea. Gimcheon promotes itself as the central city of happiness 'city image marketing'. Most of these dimensions are in the middle of planning a festival when the Manjiman Kimcheon International Family Theatre Festival Theatre Festival, and the differentiation of the other audiences that drive successful practices in terms of box office need to be determined. This paper presents the history and status of the Kimcheon International Family Theatre Festival Theatre Festival and others based on the reports point out the distinction of a 100% share of the audience for the fifth consecutive year to analyze the cause. In particular, with local art and local performing arts festivals, audiences through a combination of 'show' Theatre Festival are also indirectly involved in the 'touch and feel' willingness to participate. In the Kimcheon International Family Theatre Festival there are significant challenges for improvements in significance.

  • The development of Virtual Reality (VR)-related technologies has resulted in the improved performance of VR devices as well as affordable price arrangements, granting many users easy access to VR technology. VR drawing applications are not complicated for users and are also highly mature, being used for education, performances, and more. For controller-based spatial drawing interfaces, the user's drawing interface becomes constrained by the controller. This study proposes hand interaction based spatial drawing system where the user, who has never used the controller before, can intuitively use the drawing application by mounting LEAP Motion at the front of the Head Mounted Display (HMD). This traces the motion of the user's hand in front of the HMD to draw curved surfaces in virtual environments.

  • In this study, the simulations were carried out to show the effect of the EGR configuration in a passenger diesel engine with 2-stage turbocharger on the EGR rate. The AMESim and IFP Engine Library were used to make the program for the simulation. Three EGR configurations, HPL(high pressure loop), LPL(low pressure loop), and SLPL(semi low pressure loop), were considered. The EGR rate in the HPL and LPL EGR routes were 6.4% and 10.0% respectively but the rate in SLPL route was 18.0% and their air/fuel ratio for all three cases was 21. Therefore the SLPL EGR configuration may be positively considered in the design of the passenger diesel engine with 2-stage turbocharger.

  • Historically, the representation of the colonial period has responded closely to the policies and political conditions of the time. The Korean blockbuster , which links the genealogy of Manchuria Western, adopts a safe nationalism frame, upgrading the genre's narrative typology to colorful action and spectacle, including the Japanese army, the Liberation Army, the good and evil, and the confusion of identity. On the other hand, , which deals with the friendship of the poet and the warrior, treats the mental and internal struggles implied by the power of poetry, without resorting to familiar nationalism and heroism. is a thorough genre of rules. If the visual and sensual pleasures of imaginative resilience beyond the bounds of the law are provided within the Rules, inevitably seeks resistance within the colonial empire's legal system. Political, diplomatic, and economic conflicts between Japan and Korea, which have been continuing until recently, reaffirm the framework of nationalism on the screen.

  • Maogusi dance is an ancient ritual dance of the Tujia, a Chinese ethnic minority living in the remote region of the western Hunan Province of China. With characters, dialogues, simple story plots and unique performance procedures, it expresses ancient people's devout worship of nature, totems, ancestors, and reproduction in the uncivilized age. With the advancement of human civilization and the opening to the outside world, many dances of the ethnic minority gradually have faded out, while the Maogusi dance is still popular among the Tujia people and its spiritual symbols have been passed on through the generations. It is recognized by experts in dance and drama circles as the original source of Chinese dance and drama. From the perspectives of philosophy, religion, anthropology and folklore, this paper tries to remove the mysterious veil covering the Maogusi dance of the Tujia to explain how its ancient spiritual symbols have survived and why the original ecological consciousness has been preserved. These aims would help in understanding the deep connotation of this ancient Chinese art with its long history and profound culture.

  • Ladysmith Black Mambazo is a group of men influenced by South African traditional Zulu a cappella and American black music. The Jubilee Choir of the United States came to South Africa in the 1870s and influenced South African music while performing. Ladysmith Black Mambazo's music can be the result of the combination of the indigenous Zulu a cappella and the American Jubilee music style. This group participated in Paul Simon's album "Graceland" and became world famous. The album won a Grammy Award for sales of millions of copies. After that, they released their own albums and won 5 times Grammy Awards (nominated 15 times) They inherited and developed Zulu music under the philosophy of "preserving musical heritage". As a samely non-Western country, with hope their spirit, inheriting old one and innovating new one, gives positive inspiration for Korean music, I investigated how their music, 'Black Is Beautiful', 'Homeless' are influenced by the western music and inherited their own traditional music in it.

  • It is a time when a sustainable Korean Culture Festival strategy is needed. The Korean Culture Festival is a Hallyu Culture Festival that comprehensively introduces various Korean cultures such as Korean food, beauty, and fashion with the focus on K content, which has been leading the global craze since 2020. As the core project of the promotion of Neo Hallyu by the Ministry of Culture and Gymnasium, the 2021 Korean Culture Festival, which was based on the World K-Pop concert and the K-Culture Fan Fair, including holding the first face-to-face concert that applied the stage of real-world content after Covid-19, as well as conducting and exhibiting various fan participation challenges, must now make the leap to the global Hallyu Culture Festival. To this end, it can consist of drama, K-pop, K-Culture Fan Fair, K-Meetup, K-Culture Parade, and Awards. This distinction shows a classic festival program centered around the prosumer content that drives the Korean Wave, and in order for this philosophy to be effectively linked to its contemporaries, a Business to Business (B2B) and Business to Consumer (B2C) 'Techtainment Strategy' is needed to acquire potential customers through learned playfulness.

  • The present study examined the scientific awareness appearing in Korean tokusatsu series by focusing on Vectorman: Warriors of the Earth. As a work representing Korean tokusatsu series, Vectorman: Warriors of the Earth achieved the greatest success among tokusatsu series. This work was released thanks to the continued popularity of Japanese tokusatsu since the mid-1980s and the trend of robot animations. Due to the chronic problems regarding Korean children's programs-the oversupply of imported programs and repeated reruns-the need for domestically produced children's programs has continued to come to the fore. However, as the popularity of Korean animation waned beginning in the mid-1990s, inevitably the burden fr producing animation increased. As a result, Vectorman: Warriors of the Earth was produced as a tokusatsu rather than an animation, and because this was a time when an environment for using special effects technology was being fostered in broadcasting stations, computer visual effects were actively used for the series. The response to the new domestically produced tokusatsu series Vectorman: Warriors of the Earth was explosive. The Vectorman series explained the abilities of cosmic beings by using specific scientific terms such as DNA synthesis, brain cell transformation, and special psychological control device instead of ambiguous words like the scientific technology of space. Although the series is unable to describe in detail about the process and cause, the way it defines technology using concrete terms rather than science fiction shows how scientific imagination is manifesting in specific forms in Korean society. Furthermore, the equal relationship between Vectorman and the aliens shows how the science of space, explained with the scientific terms of earth, is an expression of confidence regarding the advancement of Korean scientific technology which represents earth. However, the female characters fail to gain entry into the domain of science and are portrayed as unscientific beings, revealing limitations in terms of scientific awareness.

  • Immersive content overcomes spatial limitations through convergence with extended reality, artificial intelligence, and photogrammetry technology along with interest due to the COVID-19 pandemic, presenting a new paradigm in the content market such as entertainment, media, performances, and exhibitions. However, it can be seen that in order for realistic content to have sustained public interest, it is necessary to study storytelling method that can increase immersion in content rather than technological freshness. Therefore, in this study, we propose a immersive content storytelling method using artificial intelligence and photogrammetry technology. The proposed storytelling method is to create a content story through interaction between interactive virtual beings and participants. In this way, participation can increase content immersion. This study is expected to help content creators in the accelerating immersive content market with a storytelling methodology through virtual existence that utilizes artificial intelligence technology proposed to content creators to help in efficient content creation. In addition, I think that it will contribute to the establishment of a immersive content production pipeline using artificial intelligence and photogrammetry technology in content production.
