The present study analyzes the content of "Suojaegi (The Account of the Suo Residence)," an essay written by the Joseon-dynasty scholar Jeong Yak-yong (丁若鏞, 1762-1836). The study identifies the work's characteristic features and significance, seeking to develop a methodology to use this essay to teach students how to write. In terms of its content, the author of "Suojaegi" asserts what it means to "protect one's self-integrity" as the word "Suo" means in the title of the residence where the author's brother Jeong Yak-hyeon(丁若鉉) lived. According to the author, his elder brother could keep on living in his house, without being sent to exile in the political turmoils, because he preserved his sense of self and adhered to his principles. The originality of the essay is attributed to the use of gi (記), a genre of writing in classical Chinese that can be translated as "record," or "account," to express his thoughts in a place of exile in the form of a dialogue with his own self. Lastly, this self-reflective essay can be served as a guide for teaching students to make their own pen names, and to write a letter of self-introduction.

This research is the case study on the course of 'Masterpiece Reading & Fine Composition Writing' in Ewha Waman's University which opens this class as a intensified writing course. In this course, part in the book of "Zhuangzi" is selected as the reading text. This research targets at highlighting the characteristics and effectiveness which appears in when the class choose the classics of Orient as writing text. This research divides the student's performance into two steps. Understanding stage and Evaluation stage. In Understanding stage, the student read part in the book of "Zhuangzi", write a discussion paper and discuss on, and in Evaluation stage, the student write the essay, depending on their previous performance in Understanding stage. This research discusses on each stage's characteristics, and analyzes the effectiveness of each ones. Especially, in the stage of Evaluation this research focuses on the relative view in perception of outside, finding self-introspection factor, and accommodating communication message. By connecting "Zhuangzi" and writing, this research tries to rediscover the era of the variety and its value, suggest the meaning of self-consciousness, and finally draw out the significance of open thought and creative writing. This research suggests on the meaningness of a modern reinterpretation on the classics and also provides the example of instructive usage of the classical text.

Dynamic treatment regimes (DTRs) are decision-making rules designed to provide personalized treatment to individuals in multi-stage randomized trials. Unlike classical methods, in which all individuals are prescribed the same type of treatment, DTRs prescribe patient-tailored treatments which take into account individual characteristics that may change over time. The Q-learning method, one of regression-based algorithms to figure out optimal treatment rules, becomes more popular as it can be easily implemented. However, the performance of the Q-learning algorithm heavily relies on the correct specification of the Q-function for response, especially in observational studies. In this article, we examine a number of double-robust weighted least-squares estimating methods for Q-learning in high-dimensional settings, where treatment models for propensity score and penalization for sparse estimation are also investigated. We further consider flexible ensemble machine learning methods for the treatment model to achieve double-robustness, so that optimal decision rule can be correctly estimated as long as at least one of the outcome model or treatment model is correct. Extensive simulation studies show that the proposed methods work well with practical sample sizes. The practical utility of the proposed methods is proven with real data example.

The present study aimed to develop new physiologically active ingredients from Angelica gigas. The polysaccharides purified from A. gigas, AGE-2c-I, showed potent anti-complementary activity in a dose-dependent manner. C₃ activation products were identified through crossed immuno-electrophoresis using anti-human C₃ antibodies and the anti-complementary activity of AGE-2c-I under Ca⁺⁺-free conditions suggests that AGE-2c-I may induce complementary activation via both alternative and classical pathways. In addition, AGE-2c-I augmented the production of various cytokines, such as interleukin (IL)-6, IL-10, IL-12, and tumor necrosis factor-α, by peritoneal macrophages. Furthermore, intravenous (i.v.) administration of AGE-2c-I dose-dependently enhanced natural killer cell cytotoxicity against YAC-1 lymphoma. In experimental lung metastasis, prophylactic i.v. administration of AGE-2c-I inhibited lung metastasis by 58% at 100 ㎍/mouse. From the above results, we suggest that AGE-2c-I purified from A. gigas has potent immune system-stimulating activities, and is a potentially promising food ingredient beneficial to human health.

In this paper, we investigated the principle of appropriation by which mythology and literature were accepted in the unique religious context of The Canonical Scripture (Jeongyeong 典經). First, we knew that almost all of the gods that appeared in the discourse of Kang Jeungsan (姜甑山) were related to Eastern Yi (東夷) mythology and deeply rooted in folklore. This is because the cultural tendency and historic consciousness of Kang Jeungsan was influenced by Danhakpa (the Danhak School 丹學派). Secondly, when we investigated the acceptance of literature into The Canonical Scripture, we discovered that Tang Poetry (唐詩), Romance of the Three Kingdoms (Sanguoyanyi 三國演義), and Journey to the West (Xiyouji 西遊記) were widely accepted in Kang Jeungsan's discourse. These works were used in diverse ways such as predictions, healing, and meditation. We knew that popular classical work like these were religiously appropriated in the context of The Canonical Scripture. Lastly, we investigated the mechanisms by which mythical and literary imagination was transformed into the Jeungsanist religious movements. Those mechanisms included the magical power of letter and images, sense-cognition of poetry, and the representational ability of mimesis. In conclusion, mythical and literary imagination helped Jeungsanist religious movements gain popularity and spread Kang Jeungsan's soteriology. This is especially true of how it transformed into unique religious techniques which functioned as key elements of the Reordering Works (公事).

Focusing on the TikTok, this paper studies the factors that influence the use intention, flow and addiction of the elderly in short videos from three aspects of media attraction, perceived usefulness and user characteristics through quantitative research methods. In recent years, influenced by various factors, more and more seniors have begun to indulge in short form videos, which will do harm to their physical and mental health. Therefore, the researchers believe it is necessary to identify the behavioral intention of seniors and the path to addiction. According to the research results, the attractiveness of TikTok and the characteristics of seniors have a positive impact on the usefulness of media. In addition, the study confirms that media usefulness has an impact on use intention and use behavior, which may develop into immersion and addiction. This study not only supplements the classical TAM theory, but also provides a reference for helping seniors to use the Internet in a healthy way. The researchers look forward to expanding the research on the various Internet platforms used by seniors in different countries and regions.

Digital morph expresses the imaginary beyond the representation of reality by expressing the narrative effect characteristically. In particular, the effect of affect can be considered to be a characteristic of digital cinema as a post-cinema. In (2013), Morphing image prominently shows the characteristics of post-cinema. By actively utilizing software technology, this film gives a shocking effect by expressing the magical image. Paying attention to the post-cinematic characteristics of morphing different from classical film, this article treated the characteristics of digital morphing. The digital morphing presents the flow of affect visualizing uncanny phenomenon of body transformation. This evokes concept of neuro-image which Patricia Pisters distinguished the neuropsychiatric pathology that appears actively on the contemporary digital screen. The Neuro-image goes beyond the temporality of Deleuze's time-image presenting future. Allegedly, the morphing of presents the neuro-images when Nina's body changed to hybrid body with black swan. Digital Morphing technique provides a shocking effect, showing delirium when the body bizarrely deformed while dancing ballet. This is different from the attraction of the morphing in film, it expresses the emotion of the neoliberal era beyond representation. In conclusion, the digital morphing presents the neuro-image system modulating the shock. This shows the characteristics of digital film which interacting and controling the shock effect as post-cinema.

Background: Incretin impairment, characterized by insufficient secretion of L-cell-derived glucagon-like peptide-1 (GLP-1), is a defining step of type 2 diabetes mellitus (T2DM). Ginsenoside compound K (CK) can stimulate GLP-1 secretion; however, the potential mechanism underlying this effect has not been established. Methods: CK (40 mg/kg) was administered orally to male db/db mice for 4 weeks. The body weight, oral glucose tolerance, GLP-1 secretion, gut microbiota sequencing, bile acid (BA) profiles, and BA synthesis markers of each subject were then analyzed. Moreover, TGR5 expression was evaluated by immunoblotting and immunofluorescence, and L-cell lineage markers involved in L-cell abundance were analyzed. Results: CK ameliorated obesity and impaired glucose tolerance in db/db mice by altering the gut microbiota, especially Ruminococcaceae family, and this changed microbe was positively correlated with secondary BA synthesis. Additionally, CK treatment resulted in the up-regulation of CYP7B1 and CYP27A1 and the down-regulation of CYP8B1, thereby shifting BA biosynthesis from the classical pathway to the alternative pathway. CK altered the BA pool by mainly increasing LCA and DCA. Furthermore, CK induced L-cell number expansion leading to enhanced GLP-1 release through TGR5 activation. These increases were supported by the upregulation of genes governing GLP-1 secretion and L-cell differentiation. Conclusions: The results indicate that CK improves glucose homeostasis by increasing L-cell numbers, which enhances GLP-1 release through a mechanism partially mediated by the gut microbiota-BA-TGR5 pathway. Therefore, that therapeutic attempts with CK might be useful for patients with T2DM.

A reflecting telescope consists of a concave primary mirror and a convex secondary mirror. The primary mirror is easy to measure, because it converges the beam from an interferometer, while the secondary mirror diverges the beam and so is not easy to measure, even though it is smaller than the primary mirror. In addition, the Korsch-type telescope uses the central area of the secondary mirror, so that the entire area of the secondary mirror needs to be measured, which the classical Hindle test cannot do. In this paper, we propose a double-stitching method that combines two separate area measurements: the annular area, measured using the Hindle stitching method, and the central area, measured using a spherical wave from the interferometer. We test the surface error of a convex asphere that is 202 mm in diameter, with 499 mm for its radius of curvature and -4.613 for its conic constant. The surface error is calculated to be 19.5±1.3 nm rms, which is only 0.7 nm rms different from the commercial stitching interferometer, ASI. Also, the two results show a similar 45° astigmatism aberration. Therefore, our proposed method is found to be valuable for testing the whole area of a convex asphere.

A method of constructing a war simulation based on Bayesian Inference was proposed as a method of constructing heterogeneous historical war data obtained with a time difference into a single model. A method of applying a linear regression model can be considered as a method of predicting future battles by analyzing historical war results. However it is not appropriate for two heterogeneous types of historical data that reflect changes in the battlefield environment due to different times to be suitable as a single linear regression model and violation of the model's assumptions. To resolve these problems a Bayesian inference method was proposed to obtain a post-distribution by assuming the data from the previous era as a non-informative prior distribution and to infer the final posterior distribution by using it as a prior distribution to analyze the data obtained from the next era. Another advantage of the Bayesian inference method is that the results sampled by the Markov Chain Monte Carlo method can be used to infer posterior distribution or posterior predictive distribution reflecting uncertainty. In this way, it has the advantage of not only being able to utilize a variety of information rather than analyzing it with a classical linear regression model, but also continuing to update the model by reflecting additional data obtained in the future.
