The purpose of this research was to examine the characteristics of typical Korean grit as opposed to Western conceptualizations. We conducted cluster analysis to identify subgroups based on three related but distinct constructs-passion(harmonious vs. obsessive) and meaning in life. Basic needs satisfaction, life satisfaction, and ego-resilience were further assessed to explore potential group-specific differences in psychological attributes. Highly gritty individuals(n=139; M=22.51 yrs) were selected by using the median. According to our results, gritty individuals were subdivided into 3 groups: the initiative who possesses highly adaptive harmonious passion and meaning in life(35.8%), the obsessive who are high in maladaptive obsessive passion(26.1%), and the passive who are the lowest in all(38.1%). The initiative grit scored the highest in all three attributes while the two other subgroups showed culturally unique patterns. Our results suggest that culture specific factors may mold differently the unfolding and psychological outcomes of grit in Korea.

Objectives: This study aimed to comprehend the characteristics of Korean medicine patterns in relation to varying degrees of cognitive impairment in an elderly population. Methods: The dataset included 127 elderly individuals with cognitive impairment obtained from three Korean medicine hospitals between 2018 and 2021. The participants were categorized into two groups based on Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores: those with questionable impairment (QI) and those with very mild dementia (VMD). A diagnostic framework for Korean medicine patterns encompassing Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire was employed. Liver blood markers, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio, were also analyzed. Results: The scores of the cognitive assessment tools (MoCA-K, MMSE-DS, and K-IADL) of the QI group significantly differed from those of the VMD group. CDR-SB exhibited a positive correlation with the scores of each pattern of Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire, whereas ALT and AST values displayed negative correlations. Binomial logistic analysis, controlling for potential confounders, such as age, education years, body mass index, the presence of chronic disease, and the presence of medication, verified that the VMD group showed higher pattern scores and lower ALT and AST values than the QI group. Conclusions: Increases in pattern scores along with decreased AST and ALT levels might be indicative of more severe cognitive impairment.

The purpose of this study is to promote the understanding of the objective of Daesoon Thought through 'examining the Objectives of Daesoonjinrihoe.' The objective of Daesoon thought was set when Kang Jeungsan Sangje descended to human world, upon the plea of divine sages, buddhas, and bodhisattvas, and determined to save the world and relieve people far and wide. For building an Earthly Paradise with Daesoon thought, Sangje carried out the great work of Reordering of the Universe for nine years and passed into heaven. Cho Jeongsan Doju, who received the heavenly religious orthodox through divine revelation from Sangje, served the late will of Sangje and established Main Tenets, Creeds, and objective of Daesoon thought. The objective set by Doju was continued to Park Wudang Dojeon and formed the Objectives of Daesoonjinrihoe. The Objectives of Daesoonjinrihoe consist of three sets of objectives in sequential order, which are related in organic, mutual beneficient, and integrative with one another. The Objectives starts from individual cultivation and expand into worldly reformation: 1)one's Spiritual transformation through Guarding against self-deception 2)Renewal of human beings through Realizing Earthly Immortality 3)Opening of new world through Building of Earthly Paradise. Also, in these Objectives of Daesoonjinrihoe, Three Realms of Heaven, Earth, and Humanity keep close relations to enter into new world. These Objectives are based on the 'thought of mutual beneficence' and are realized with Daesoon thought, which is the Dao of 'Crowned King' that goes beyond the previous thoughts of Confucianism, Buddhism and Taoism. Objectives of Daesoonjinrihoe have following details in each objective as following; (1) 'Guarding against self-deception-Spiritual Transformation' is for human nature. In Daesoon thought, human has the potential to restore conscience, which is true nature, and return to undefiled essence by 'guarding against self-deception'. In other words, it views that one can reach into the stage of spiritual alignment with the Dao once he recovers conscience through cultivation of Daesoonjinrihoe based on the idea of 'Guarding against self-deception'. (2) 'Realizing Earthly Immortality-Renewal of human beings' is for ideal human character. 'Realizing Earthly Immortality' in Daesoon Thought indicates the advent of ideal human beings called 'Dotong gunja'(virtuous beings who are aligned with the Dao). They are leaders who integrate politics and religion in helping people to renew themselves and make the world into Earthly Paradise. (3) 'Building an Earthly Paradise-Opening of new world' is for ideal society. Daesoon thought aims to making a peaceful world by creating an ideal society of heaven on this earth. Park Wudang Dojeon, who led Daesoonjinrihoe, emphasized the importance of Three Basic Activities: Spreading of Sangje's virtue, Edification, and Cultivation: and Three Major Activities: Aid and charity, Social welfare, and Education. Dojeon said "One should make effort to reach the utmost goodness through enlightening their bright virtue and cultivating their talent virtue." In this words, he made clear that the Objectives of Daesoonjinrihoe can be realized when people enlighten their bright virtue and cultivate themselves with their talent virtue. In conclusion, the Objectives of Daesoon thought were clarified of their meanings by Sangje, established into laws by Doju, and actualized by Dojoen in various activities of Daesoonjinrihoe.

Automatic Music Transcription (AMT) is a task that detects and recognizes musical note events from a given audio recording. In this paper, we focus on reducing the latency of real-time AMT systems on piano music. Although neural AMT models have been adapted for real-time piano transcription, they suffer from high latency, which hinders their usefulness in interactive scenarios. To tackle this issue, we explore several techniques for reducing the intrinsic latency of a neural network for piano transcription, including reducing window and hop sizes of Fast Fourier Transformation (FFT), modifying convolutional layer's kernel size, and shifting the label in the time-axis to train the model to predict onset earlier. Our experiments demonstrate that combining these approaches can lower latency while maintaining high transcription accuracy. Specifically, our modified model achieved note F1 scores of 92.67 % and 90.51 % with latencies of 96 ms and 64 ms, respectively, compared to the baseline model's note F1 score of 93.43 % with a latency of 160 ms. This methodology has potential for training AMT models for various interactive scenarios, including providing real-time feedback for piano education.

This study examines the vocational adjustment experiences of elderly men who chose a creative occupation after retirement. The aims are to understand the related meanings and to provide specific empirical data on the elderly who hope to start a creative occupation. Five men aged 65 years or older who chose a creative occupation after retirement were enrolled in the study. Data were collected through in-depth interviews with the participants. The collected data were qualitatively analyzed, and a total of 7 categories, 25 subcategories, and 132 concepts were identified. The seven categories were "challenge led by a sense of freedom," "reflection of the need for 'fun,'" "difficulties and limitations felt by a non-expert," "concerns and effort to afford the increasing expenses," "joy for accomplishment," "ways to utilize my creativity," and "reward from increased social participation." The participants felt that adjusting to a creative occupation was a process by which their potential creativity was expressed. They felt the joy of working that they had not felt before, and the series of processes by which they overcame difficulties during work and increased their social participation were in line with the goals of creative aging. In order to help older adults in Korea to choose and adjust to creative occupations in their older adulthood, there is a need for creative-occupation-related education prior to retirement and for various policies and practical efforts that consider the change of social environment. Furthermore, our findings suggest that choosing a creative occupation after retirement is an effective measure for promoting successful aging among the elderly in Korea.

Transmembrane protein TMEM16A, which encodes calcium-activated chloride channel has been implicated in tumorigenesis. Overexpression of TMEM16A is associated with poor prognosis and low overall survival in multiple cancers including lung adenocarcinoma, making it a promising biomarker and therapeutic target. In this study, three structure-related sesquiterpene lactones (mecheliolide, costunolide and dehydrocostus lactone) were extracted from the traditional Chinese medicine Aucklandiae Radix and identified as novel TMEM16A inhibitors with comparable inhibitory effects. Their effects on the proliferation and migration of lung adenocarcinoma cells were examined. Whole-cell patch clamp experiments showed that these sesquiterpene lactones potently inhibited recombinant TMEM16A currents in a concentration-dependent manner. The half-maximal concentration (IC50) values for three tested sesquiterpene lactones were 29.9 ± 1.1 µM, 19.7 ± 0.4 µM, and 24.5 ± 2.1 µM, while the maximal effect (E_max) values were 100.0% ± 2.8%, 85.8% ± 0.9%, and 88.3% ± 4.6%, respectively. These sesquiterpene lactones also significantly inhibited the endogenous TMEM16A currents and proliferation, and migration of LA795 lung cancer cells. These results demonstrate that mecheliolide, costunolide and dehydrocostus lactone are novel TMEM16A inhibitors and potential candidates for lung adenocarcinoma therapy.

Background: Exposure levels for heavy metals such as lead (Pb), mercury (Hg), and cadmium (Cd) have increased due to human activities. They are known to be a public health concern. Objectives: This study aimed to determine the exposure levels to heavy metals in the blood and urine of South Korean adults and to present the contribution rate of exposure pathways using an exposure algorithm for men aged 19~64, women aged 19~64, and all seniors aged 65 or older. Methods: We analyzed data from the Korean National Environmental Health Survey (KoNEHS) Cycle 4 (2018~2020). A total of 2,646 participants aged ≥19 years were included. Multiple regression analysis was performed to determine the factors affecting heavy metal concentrations. The contribution rate was calculated by applying three exposure algorithms for ingestion, inhalation, and dermal exposure. Results: Factors that commonly affect heavy metal concentrations in blood and urine were gender and age. The main influencing factors for Pb and Cd were education level and smoking status, while frequency of fish consumption and of alcohol consumption were indicated to be the main influencing factors for mercury. The contribution rates of lead and cadmium from food ingestion were 78.03~79.62% and 88.39~92.89%, respectively. Additionally, the highest contribution for mercury was accounted for by food at 81.69~85.77%. As a result of the risk assessment, cadmium was found to pose a potential health risk a with total cancer risk (TCR) of more than 1×10^-6. Conclusions: The KoNEHS could be an important study for determining the level of exposure to heavy metals and their influencing factors. Integrated exposure to heavy metals could assess the main exposure pathways, and this methodology could be applied to exposure management of heavy metals.

This study purports to explore the landscape of welfare attitudes of young generation of Korea in their 20s and 30s focusing upon potential differences from those of older generations. Korea has recently been in the significant debate on pension reform and the disadvantages of relatively young generations has been on of the most crucial issues during the reform. Survey data from 17th Korean Welfare Panel are analyzed and such variable as attitudes toward government expenditure on public pension, health care, old age support, poverty, family and child care and so on. In addition, welfare-related variables such as universalism vs selectivism, tax increase for welfare expenditure, and political orientation are to be analyzed. The results show several findings. First of all, correspondence analysis shows that young generation in Korea are strongly associated with higher education and full time employment compared to older generations. Secondly, the most interested welfare issues of young generations are housing and child support. Moreover, young generations' attitudes toward government expenditure increase differ from those of older generations on the issues of public pension, housing, and family and child support. Lastly, political orientation of those young generation tend to be progressive and they support universalism in welfare policy, but they do not support tax increase for welfare purpose, which, I would say, is inconsistent.
