HYBE Insight, opened in May 2021, is an exhibition space that visually displays and re-interprets the BTS Universe and its content. The space echoes the identity of BTS as an artist and the specificity of the cultural phenomenon they have generated. This study analyzes HYBE Insight's BTS exhibition by applying new museological theories and discourses. Based on a qualitative research methodology including literature review and observational method, the primary themes of the exhibition are follows: 1) a contextualized exhibition content presenting the identity of BTS and their music, 2) the role of the fandom Army's participation in (re) producing BTS content related to the characteristic of popular music museums, 3) the elements of convergence art and its contemporary implication, 4) and the illumination of cultural value in popular music museum management. As the pivotal theory of new museology suggests, investigating a specific exhibition based on each context it has created is significant. However, those studies, including exhibitions related to popular music/artists, were mostly developed in Western nations. In this respect, HYBE Insight's BTS exhibition provides considerable room to explore. In addition to the recent research on BTS, such as their convergent artistry, socio-cultural influence, the role of Army, and the characteristics of HYBE's content management, this article aims to contribute to the multifaceted research by scrutinizing the BTS exhibition content from the new museology perspective.

In this paper, we propose an image downscaler used in multimedia video applications, such as DTV, TV-PIP, PC-video, camcorder, videophone and so on. The proposed image downscaler provides a scaled image of high-quality and high-performance. This paper will explain the scaling theory using two-dimensional digital filters. It is the method that removes an aliasing noise and decreases the hardware complexity, compared with Pixel-drop and Upsamling. Also, this paper will prove it improves scaling precisians and decreases the loss of data, compared with the Scaler32, the Bt829 of Brooktree, and the SAA7114H of Philips. The proposed downscaler consists of the following four blocks: line memory, vertical scaler, horizontal scaler, and FIFO memory. In order to reduce the hardware complexity, the using digital filters are implemented by the multiplexer-adder type scheme and their all the coefficients can be simply implemented by using shifters and adders. It also decreases the loss of high frequency data because it provides the wider BW of 6MHz as adding the compensation filter. The proposed downscaler is modeled by using the Verilog-HDL and the model is verified by using the Cadence simulator. After the verification is done, the model is synthesized into gates by using the Synopsys. The synthesized downscaler is Placed and routed by the Mentor with the IDEC-C632 0.65${\mu}{\textrm}{m}$ library for further IC implementation. The IC master is fixed in size by 4,500${\mu}{\textrm}{m}$$\times$4,500${\mu}{\textrm}{m}$. The active layout size of the proposed downscaler is 2,528${\mu}{\textrm}{m}$$\times$3,237${\mu}{\textrm}{m}$.

Recently, the convergence of information technology with bio-technology, nano-technology or other technologies has been creating a new paradigm. In a field of transportation, the intelligent transport systems which is a convergence of intelligent technologies and transportation systems have been studied. The Variable Speed Limit(VSL), is one of ITS technologies, is thought to improve safety and efficiency of transportation while controlling speed limit based on road conditions. Legacy studies have considered only one station for VSL algorithm. However, it is not appropriate for an urban freeway installed with many stations. In this paper, new algorithm is proposed to not only enhance effectiveness of VSL based on cooperation of stations but also reflect road conditions within 30 seconds. The proposed algorithm consists of 4 steps: the first is a "searching bottleneck station" step, the second is a "calculating a size of congestion" step, the third is a "calculating the number of controlled stations" step, the final is a "calculating VSL" step. This algorithm guarantees improved safety and minimum additional travel time. The travel time should be considered because drivers would against the VSL algorithm when the proposed algorithm occurs additional travel time. In our experiments, microscopic traffic simulator VISSIM is selected to perform a modeling work. The results show that proposed algorithm provides the improved safety and minimum increase of travel time.

Recently, the biochip which is a prime representation of NT, IT, BT, as an example of convergence technology, has been frequently mentioned. With the recent rapid advance in biotechnology, these compact devices, such as lab-on-a-chip or u-TAS, have been developed, and more research is needed. These compact devices typically use the micro-channel in order to shed or detach and mix a variety of materials. Specially, in micro-fluidic systems, a mixer is necessary to produce a mixture because only laminar flow occurs at a low-Reynolds number. To solve this problem, HVM a micromixer that induces a horizontal and vertical multi-mixing flow motion, is proposed. The mixing performance was analyzed and verified by optimizing the shape through the CFD analysis and evaluating the structural analysis and the soundness with material properties that are obtained through the basic experiment.

일반적으로 기술융합이라는 용어는 IT, BT, NT 등 성격이 다른 큰 범주에서 기술간의 결합으로 인식되고 있다. 현재까지의 기술융합 연구들은 IT기술을 중심으로 한 융합과 관련 국가 정책에 관한 것이 대부분을 차지하고 있어 큰 기술 범주 위주에 국한되어 있다. 하지만 동일한 목적을 위해 수행하는 유사 기술영영에서의 기술융합 역시 기술혁신의 수단으로 간과할 수 없는 영역이다. 실제로 미국, 유럽 등의 선진국에서는 기술융합 전담기관을 신설하여 프로젝트 내의 기술간 융합에 관심을 갖고 있지만, 국내에서는 프로젝트 범위의 기술융합 가능성 및 실효성에 대한 연구가 부족한 실정이다. 이에 본 연구에서는 지식경제부에서 수행하는 가스하이드레이트 연구개발사업을 실증사례로 하여 프로젝트 범위의 기술 융합에 관하여 기술융합의 필요성, 적용가능성, 실효성에 초점을 맞추어 고찰하였다. 가스하이드레이트 개발 사업은 지식경제부 내 가스하이드레이트 개발사업단 주관으로 2005년에 시작되었으며 2014년까지 I 지역 탐사 및 시추, II 지역 탐사 및 시추, 시험생산의 3단계의 달성목표를 가지고 있다. 가스하이드레이트는 천연가스가 저온 고압 상태에서 물과 결합해 형성된 고체 에너지로 화석연료 고갈에 따라 이를 대체할 가장 유력한 청정에너지원으로 주목받고 있다. 현재 가스하이드레이트 개발사업단에서는 지구물리탐사분야 지질지화학분야 개발생산분야로 세부 기술모듈을 형성하여 목표달성을 위해 노력하고 있지만, 중과제간 교류가 부족한 상황으로 인해 목표달성을 위한 기술력의 확보 및 향후 상업생산에 대한 불확실성이 증가하고 있는 상황이다. 이와 같은 상황을 해결하기 위해서 기술개발 및 혁신의 수단인 기술융합의 필요성이 증가하고 있다. 기술혁신은 기초연구, 응용연구, 개발, 학습, 투자 등의 일련의 과정을 거쳐 경제적 성과와 사회적 영향을 만들어내는 개념으로 정의 할 수 있다. 기술혁신을 이루어내는 가장 중심적인 역할을 담당하는 기술융합은 2개 이상의 요소기술들이 결합하여 기술이 갖지 않는 새로운 기능을 발휘하는 기술혁신의 한 현상으로 정의할 수 있다. 기술융합은 21세기 초에 접어들어 급속하게 변화하는 양상을 보이며 예상보다 경제에 더 큰 영향을 미치고 있다. 가스하이드레이트 각 단계에서의 애로점을 극복하기 위한 기술혁신을 위해 지구물리탐사 지질지화학 개발생산분야간의 융합의 가능성 등을 타진해본 결과, 각 기술융합들을 기술융합 유형에 맞춰 분류할 수 있었으며 유형별 적용가능성과 기대효과 측면에서 비교분석을 수행하였다. 분석의 정밀도를 높이기 위하여 기술융합 유형에 대한 이론과 실제 가스하이드레이트 전문가들과의 설문을 통해 비교분석을 실시하였다. 가스하이드레이트 실증 사례에 대한 분석 결과, 기술융합 이론은 기존의 큰 기술범주뿐만 아니라 작은 범주에도 적용할 수 있으며, 필요성과 적용가능성, 실효성 면에서도 충분한 고찰을 통해 기술융합 이론의 적용 범위를 좁히면 더 많은 연구와 융합기술을 얻을 수 있다는 결론을 얻을 수 있다.

The purpose of this paper was to prepare and evaluate solid dispersions (SD) that can increase the dissolution rate of dexibuprofen as a model drug with low solubility in water using saccharides and sugar alcohols as dispersion materials. DSC, XRD, content and content uniformity test, dissolution test, and disintegration test were conducted for physicochemical evaluation of the prepared SD. For the results, it was confirmed using differential scanning calorimetry that fructose, which has a melting point around 120 ℃ of the device operating temperature range, is a suitable excipient for the preparation of SD by the rotary hot-melt granulation (RHMG) method. X-ray diffraction analysis was conducted to confirm that the crystallinity of dexibuprofen was reduced. Disintegration test of the prepared tablet using SD-containing dexibuprofen and fructose confirmed a very fast disintegration time within 1~2 seconds and also showed that the dissolution rate was about 20% faster than that of the dexibuprofen raw material. Dexibuprofen with reduced crystallinity by SD confirmed through the RHMG method can be used to increase the dissolution rate of the drug and increase the disintegration time of the tablet. Thus, it can be used in the manufacturing of various solid preparations.

Today, the Korean wave headed by K-pop is newly named as 'New Korean Wave' in that it has been extended to United States, Europe and Russia. K-POP, the main player of the new Korean wave, has been successful in SNS marketing channels. Furthermore, the content of K-pop has attracted the attention of the global audience. The media and public attention on the Korean Wave is meaningful because it is not merely a cultural export. It also makes Korean people feel national pride, seeing the mental influence of its culture on other regions. Moreover, the development of the cultural industry in our society, which is different from industrial or material development, is a proof that Korean society is at the center of globalization. Until the 20th century, Korean culture had been rather receptive than dominant. In other words, it was focused more on acceptance of other cultures than active creation or outflow of its own. Now, however, K-POP is not anymore copying Western culture. It is creating its own unique characters, which makes K-pop very competitive. Korean culture has been formed for a long time in Korea's unique historical background. Korean popular culture also has to establish a solid foothold in world markets through its distinctive and traditional feature. The positive consumer response to Korean pop culture will create the added value of Korean contents and their derivatives, which will heighten Korea's national image also. In other words, if traditional art and K-POP are converged and equipped with our own unique and highly artistic culture, they will take the lead in the global cultural art market. In this study, we will recognize the possibility, growth and development of K-pop culture and analyze the cases of combining K-pop and Korean traditional art. First, we have to blend traditional art and other various genres to create diverse contents, and we have to actively utilize media channels. Second, we must improve people's awareness of the copyrights of traditional art. Also, we have to mitigate the copyrights of creative dance to expand the disclosure of contents which can be utilized. Third, we have to learn about traditional arts from younger age. Fourth, we will expand traditional arts to the whole of Korean cultural policies, which can enhance the nation's cultural value and create economic benefits. These four are expected to be effective ways to preserve the identity of traditional art and at the same time, globalize Korean culture.

This paper seeks to raise inflection points of battery manufacturing bases in Korea in the V4 region through the reorganization of new industrial technologies in accordance with ESG. As a result, the global supply chain market is cut off. The Russian-Ukraine war and the U.S.-China hegemony are competing in the economic crisis caused by COVID-19. It is showing diversification of new suppliers in an environment where mineral, grain procurement, gas, and even wheat imports from China and Russia are not possible. As a protective glocal, this area is used as a buffer zone(Pro-Russia, Hungary). to an isolated zone(anti-Russia, Poland) by war. In this paper, economic growth is expected to slow further due to the EU tapering period and high inflation in world countries. Due to these changes, the conversion of new tech industry and the contraction of Germany's structure due to energy supply may lose the driving force for economic growth over the past 20 years. This is caused by market disconnection(chasm) in the nominal indicators in this area. On the other hand, Korea should actively develop into the V4 area as an energy generation export (nuclear and electric hydrogen generation) area as a bypass development supply area due to the imbalance in the supply chain of rare earth materials that combines AI. By linking this industry, the energy platform can be scaled up and reliable supply technology (next generation BT, recycling technology) in diversification can be formed in countries around the world. This paper proves that in order to overcome the market chasm caused by the industries connection, new energy development and platform size can be achieved and reliable supply technology (next-generation battery and recycling technology, Low-cost LFP) can be diversified in each country.

Psy's Gangnam style in 2012 showed K-pop's potential for global growth and BTS proved it by reaching three consecutive Billboard No.1. The success in the global music market brings tremendous economical and cultural power. This study is conducted for the continuous growth of K-pop music in the global music market by analyzing the musical factor of K-pop's global success. The top 20 most-viewed K-pop MV on Youtube is chosen as a research subject because Youtube is a worldwide platform that reflects global popularity. For the process of K-pop music creation, the role of the composer is expanded and many overseas producers participate in music creation. All 20 songs are created by the collective creation system and there is a consecutive collaboration between the main producers and certain artists. The top 20 most viewed K-pop songs have the musical characteristics of transnational genre convergence, hook songs, sophisticated sounds, frequent use of English lyrics, a reflection of the latest global trends, rhythm optimized for dance and clear concept. It makes the K-pop song easily remembered and familiar to overseas listeners. K-pop's healthy and fresh theme brings emotional empathy and reflects Korean sentiments. K-pop's global success is not a coincidence, but a result of continuous efforts to advance overseas. Some critics criticize K-pop's musical style is similar and it shows K-pop's limitation but K-pop progressed its musical evolution. By keeping the merits of K-pop's success factors and complementing its weak points, K-pop will continue its popularity and increase influence in the global music market.
