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.

The purpose of this study is to identify the characteristics and factors of each area by considering the gender health of the elderly as the integration of mental, physical, emotional, and social gender health based on the WHO gender health. The sexual health of the elderly is significantly different by gender, academic background, and region, and there is a clear difference in mental, physical, emotional sexual health and social sexual health. The mental, physical and emotional sexual health of the elderly in urban areas, those with high education and male is high, but the elderly in the rural areas, those with low education, and female are high in social sexual health. The factors affecting sexual health are as follows. Mental sexual health was positively influenced by satisfaction of sexual life and sexual knowledge. Physical sexual health was positively influenced by life and spouse satisfaction, and emotional sexual health was positively influenced by sexual relationship, spouse satisfaction, sexual life satisfaction and sexual knowledge. Social sexual health has a negative (-) effect on spouse satisfaction and sexual relationships. Integrated sexual health in old age can affect subjective health and quality of life, leading to successful aging. Sexual health education is needed to form a safe and healthy sexual life and interpersonal relationship. The 'sex' that appears as a cumulative trajectory of life should be accompanied by the accurate sexual health awareness and sex education that encompasses all generations. Therefore, in the composition of sex health education program, it is necessary to reflect the components that can enhance the sensitivity of adulthood to strengthen understanding and communication of spouse.

Graphite has been used as an anode material for lithium-ion batteries for the past 30 years due to its low de-/lithiation voltage, high theoretical capacity of 372 mAh/g, low price, and long life properties. Recently, all-solid-state lithium-ion batteries (ASSLB), which are composed of inorganic solid materials with high stability, have received great attention as electric vehicles and next-generation energy storage devices, but research works on graphite that works well for ASSLB systems are insufficient. Therefore, we induced the performance improvement of ASSLB anode electrode graphite material by removing the amorphous carbon present in the carbon material surface, acting as a resistive layer from the graphite. As a result of X-ray diffraction (XRD) analysis using heat treated graphite in air at 400, 500, and 600 ℃, the full width at half maximum (FWHM) at (002) peak was reduced compared to that of bare graphite, indicating that the crystallinity of graphite was improved after heat treatment. In addition, the discharge capacity, initial coulombic efficiency (ICE) and cycle stability increased as the crystallinity of graphite increased after heat treatment. In the case of graphite annealed in air at 500 ℃, the high capacity retention rate of 331.1 mAh/g and ICE of 86.2% and capacity retention of 92.7% after 10-cycle measurement were shown.

As COVID-19 has been converted to an endemic with social distancing lifted, people are getting used to new cultures and lifestyles that are different from before. While the world is now adapting to rapidly changing trends, Christian education is facing a crisis without being able to respond to these changes. Therefore, a new Christian education method is now required. The purpose of this study is to suggest a new Christian education method that allows Christians to properly lead a new era as an alternative to Christian education that is experiencing such a crisis. The study also presents the metaverse Christian education platform, which is a detailed and practical method of Christian education, by incorporating the platform and metaverse that are under the spotlight in the post-Corona era into Christian education. Here, the christian educational platform refers to the system, space, and various materials that can make Christian education efficient and smooth. The metaverse Christian education platform consists of 4 stages according to the size of the platform to activate supply and demand within the platform. Stage 1 is a home education platform, Stage 2 is a community education platform, Stage 3 is a regional union education platform, and Stage 4 is an educational mission platform. The last Stage 4, the educational mission platform utilized the metaverse, which is drastically expanding in the present era, as a method of educational mission. It is meaningful that the educational mission has been embodied by providing small churches and the next generation in underdeveloped countries with educational contents, educational materials, online mentors, virtual communities, and real-time educational broadcasts within the educational platform, using virtual spaces in the metaverse.

To prepare an atmospheric correction model suitable for CAS500-4 (Compact Advanced Satellite 500-4), this letter examined an atmospheric correction experiment using Sentinel-2 images having similar spectral characteristics to CAS500-4. Studies to compare the atmospheric correction results depending on different Aerosol Optical Depth (AOD) data are rarely found. We conducted a comparison of Fast Line-of-sight Atmospheric Analysis of Spectral Hypercubes (FLAASH), Sen2Cor, and Second Simulation of the Satellite Signal in the Solar Spectrum - Vector (6SV) version 1.1 and 2.1, using Geo-Kompsat 2A (GK2A) Advanced Meteorological Imager (AMI) and Aerosol Robotic Network (AERONET) AOD data. In this experiment, 6SV2.1 seemed more stable than others when considering the correlation matrices and the output images for each band and Normalized Difference Vegetation Index (NDVI).

Recently, the recommender system has been widely used in various fields such as movies, music, online shopping, and social media, and in the meantime, the recommender model has been developed from correlation analysis through the Apriori model, which can be said to be the first-generation model in the recommender system field. In 2005, many models have been proposed, including deep learning-based models, which are receiving a lot of attention within the recommender model. The recommender model can be classified into a collaborative filtering method, a content-based method, and a hybrid method that uses these two methods integrally. However, these basic methods are gradually losing their status as methodologies in the field as they fail to adapt to internal and external changing factors such as the rapidly changing user-item interaction and the development of big data. On the other hand, the importance of deep learning methodologies in recommender systems is increasing because of its advantages such as nonlinear transformation, representation learning, sequence modeling, and flexibility. In this paper, among deep learning methodologies, RNN, CNN, and GAN-based models suitable for sequential modeling that can accurately and flexibly analyze user-item interactions are classified, compared, and analyzed.

John Woo's A Better Tomorrow arrived at the turning point of Korean society between 1987 and 1988. The Hong Kong movie boom that started here reached its peak around the 1990s. What does this phenomenon mean? Hong Kong action films have functioned as an important resource for Korean young male subculture since the late 1960s. The audience of A Better Tomorrow matches the audience of previous Hong Kong films in a generational and gendered way. The fascination of Hong Kong action films by young Korean men from 1987 to 1991 has nothing to do with Hong Kong's political context. However, a certain affect is shared between Korean and Hong Kong audiences. It could be said to be the brotherhood within the struggling group. The affective economies of this fraternity embodies the broad solidarity of 1987, the solidarity of comrades seeking to resist the violence of the world. It also works on symbolic and practical gender bias. In other words, this loyalty is nothing but loyalty between the (male) brothers who are confronting the injustice of the world. This is the "translational possibility" of A Better Tomorrow.

This article pays attention to the gender representation of an abominable male abject that reveal class polarization in the movie Parasite. I seeks to read a new aspect of emotional politics in which a precariat man becomes a male patriarch while representing himself with an abhorrent position. Parasite shows a reversal of daughter and son responsible for parents, contrary to the existing family narrative. They teaches the parents' generation how to survive neoliberal that their place is created only when they take away others' place. However, after losing this prospect, Ki-woo confesses to his father that he is sorry first. Ki-taek also attempted to identify Dong-ik with the patriarch, but this male solidarity collapsed by class and committed murder in sudden anger. As a result, Gi-taek goes down to the hateful status of a stinking underground life, and Ki-woo receives a message of ethical reflection from his isolated father. The film gives the father and son the noble status of ethical fighter who fought against the structure of class polarization, especially the ending epilogue and narration emphasizing the ethical responsibility and mutual solidarity between father and son. In this process, the voices of female characters are gradually omitted, blurring gender screening for male characters. Parasite reveals the political reenactment strategy of precariat men in the age of neoliberalism, which is ethical subject by claiming to be a class abject himself. And representing the hate with gender-selecting, it is beautifying the responsible ethics of the patriarch.
