To characterize gene expression that is dependent on the strength of calorie restriction (CR), we obtained transcriptome at different levels of glucose, which is a major energy and carbon source for budding yeast. To faithfully mimic mammalian CR in yeast culture, we reconstituted and grew seeding yeast cells in fresh 2% YPD media before inoculating into 2%, 1%, 0.5% and 0.25% YPD media to reflect different CR strengths. We collected and characterized 160 genes that responded to CR strength based on the rigorous statistical analyses of multiple test corrected ANOVA (adjusted p value < 0.1 or raw p value < 0.0031) and Pearson correlation (|r| > 0.7). Based on the individual gene studies and the GO Term Finder analysis of 160 genes, we found that CR dose-dependently and gradually increased mitochondrial function at the transcriptional level. Therefore, we suggest these 160 genes are markers that respond to CR strength and that might be useful in elucidating CR mechanisms, especially how stronger CR extends life span more.

Nowadays, lithium-ion battery has become more popular around the world. Knowing when batteries reach their end of life (EOL) is crucial. Accurately predicting the remaining useful life (RUL) of lithium-ion batteries is needed for battery health management systems and to avoid unexpected accidents. It gives information about the battery status and when we should replace the battery. With the rapid growth of machine learning and deep learning, data-driven approaches are proposed to address this problem. Extracting aging information from battery charge/discharge records, including voltage, current, and temperature, can determine the battery state and predict battery RUL. In this work, we first outlined the charging and discharging processes of lithium-ion batteries. We then summarize the proposed techniques and achievements in all published data-driven RUL prediction studies. From that, we give a discussion about the accomplishments and remaining works with the corresponding challenges in order to provide a direction for further research in this area.

Smart devices have become an essential part of human life; however, excessive dependency on these devices has become a serious issue for both children and adults. In this study, a research model was developed which hypothesized that mothers' smartphone addiction influences children's media dependency, and that this effect is sequentially mediated by mothers' work-family strains and parental monitoring. To test this hypothesis, an analysis of data from the 13th Wave of Panel Study on Korean Children (PSKC), conducted in 2020, was performed. The data were collected from 726 children (359 boys, 367 girls) with an average age of 12.23 years (SD=.30). The analysis was conducted using SPSS 27.0 and Process MACRO Ver. 4.2. The results were as follows. Maternal smartphone addiction increased mothers' work-family strains, which in turn lowered the level of parental monitoring, which was associated with an increase in children's media dependency. Furthermore, mothers' smartphone addiction had a partial mediation effect on children's media dependency. In sum, this study revealed that the mothers' smartphone addiction increased children's media dependency, and this effect was sequentially mediated by an increase in mothers' work-family strains and a decrease in parental monitoring. This study verifies that mothers' smart device usage as well as their working environment has a significant effect on children's media dependency. Therefore, to increase parental monitoring of children's media usage, mothers' work-family strains need to be reduced.

The purpose of this study is to research the effect of life satisfaction on young people at an early age and the impact of media on behavioral aggressiveness during this process. To this end, a group of primary schools located in Jiangnan and Jiangbei in the Seoul area and the Nanjing Road in the city were selected and 290 early youths from grades 4-6 of elementary school were chosen as specimens of structural equations. The results indicate that firstly, the personal causes of early youth have a positive (+) effect on the self-esteem life satisfaction and negative (-) impact on liquidity aggressiveness. Secondly, depression has a negative impact on life satisfaction, while action aggressiveness has no effect. Thirdly, the mobility aggression of early youth has a negative impact on life satisfaction (-), and there is a partial media relationship between self-esteem and life satisfaction. However, there is no media relationship between depression and life satisfaction. Based on the above research results, the project of improving youth early life satisfaction and reducing mobile aggression was proposed.

IPP isomerase (Iso) and Limonene synthase (Limo) are important enzymes in terpenoids biosynthesis pathway. The wild type and each metabolically engineered (Iso and Limo) transgenic spearmint (Mentha spicata Linne) plants were compared for their growth patterns and the contents of essential oil in in vitro culture media. The profile of terpenoid metabolites was obtained from the essential oil of the metabolically engineered transgenic spearmint, which was extracted using a modified SDE method, by GC-MS analysis. The growth of wild spearmint was more profuse in B5 culture medium than in other media. Significant differences in leaf and root growth patterns were observed between metabolically engineered transgenic and wild type spearmint plants. The leaves of the transgenic spearmint plants were slightly elongated but were dramatically narrower than those of wild type spearmints. The content of essential oil of transgenic spearmint was different slightly depending on the target terpenoid genes. The content of essential oils in Limo transgenic plants was higher than that of Iso, except for transgenic plant in B5 medium. The transgenic spearmint produced more terpenoids than the wild type. Iso spearmint extracts showed eleven terpenoids and a phenylpropane, while Limo spearmint extracts contained nine terpenoids. However, extracts from the wild type showed the presence of only four terpenoids.

Ostermeier's Hamlet has no particular contemporary reinterpretation. Alternately devoting to show retrospect in illusion and existence through revenging actions. However, Shakespeare's metaphorical and implicative language is dissipated and the style of the play is not an illusive space-time, but a tragic theatrical production that uses rough language to express the depth of the story. The Perfomance of Hamlet is a sensuous jumble up of a diverse range of mass media. The double roles that the actors carry out give an affect of isolation between the audience and the play itself showing both empathy and liberty. Ostermeier's Hamlet distinctively shows a post-modern performance through the prominent elements of dirt, the use of mixed genre, theatric emphasis, making an image and the fulfillment of acting. Nonetheless, Ostermeier's performance stays off the point on the breakup strategy of the post-modern drama without suspending the narrative of Shakespeare's Hamlet. Besides aiming to show a performance centered by the imagery of physical expression, his performance shows New Realism in the 1960's, showing everyday life. Ostermeier thinks, that theatre helps give contemporary people an accurate reality check in the constant unstable periods of time. Therefore, Hamlet shows post-modern physical expression and outspoken dramaturgy using the effects of mass media in New Realism without breaking up realistic narration. With being the aberration of the Castle Helsingor, the main character Hamlet, expresses lunacy and can be considered as metaphor for young adults whom are broken down and isolated from the economic system. He is a substitute for those who experience agony, anger, torment, etc. and other suppressed emotions in everyday life. With the method of direction in the portrayal of Hamlet show signs of succession in the abundant popularization of the classics by communicating with the audience by following the trend of modern mass media and audio-visual perception; emphasizing the point of the philosophical topic 'life and death,' 'life and theatre,' and 'illusion and reality.'

The effect of the addition of the fresh medium, volume of under solid medium in double layer culture as well as the medium change after pretreating microspores on the production of embryos in microspore culture of hot pepper (Capsicum annuum L.) has been studied. When cultured after heat pre-treatment, changing pretreatment media with fresh culture media proved to be more effective for embryo production rather than supplementing additional culture media. Heat-pretreating for 3 days turned out more effective for embryo production than pretreating for 1 or 2 days. In the case of anther pretreatment, the addition of fresh medium after culture was not effective for embryo production. In pretreating microspores, however, supplementing additional fresh culture media greatly improved embryo yield and quality. The best time point of media addition was 4 days after culture commenced, and the most effective number of times of media addition was one time addition. Moreover, the effective volume of added medium in double layer culture for embryo production was 1.5 ml. The addition of media more than 1.5 ml reduced both embryo yield and quality. Double layer medium was more effective for embryo development than liquid medium. When the volume of under solid medium increased ranging from 3 ml to 7 ml, more cotyledonary embryos were produced in either 5 ml or 7 ml compared to 3 ml, even though the total number of embryos were highest in 3 ml. These results can be used as an important data for establishing an efficient microspore culture system for producing high frequency of normal embryos in hot pepper.
