The view of social responsibility activities from the pioneer studies found that most research is mainly limited to the corporate social responsibility activities. The related studies on the individual level are very few. Therefore, it is very necessary to make a clearer and more systematic empirical research for the global companies whose employees are directly involved in the companies' social responsibility activities. In order to find the relationship between variables, we collected data from chinese employee of Korean firms which located in China. The result of empirical test is as follows; First, the social responsibility activities of the individual level have a significant positive effect on the employees' job satisfaction and organization inputs. In other words, social responsibility activities could improve the employee's job satisfaction and organization inputs. Second, innovative organizational culture of South Korean companies has a significant positive effect on the individual level social responsibility activities. Third, transformational leadership of the CEO in South Korean have no effect on personal level social responsibility activities. Fourth, the CEO'S ethical values have great positive effect on personal level of social responsibility activities. Through the analysis we can see, in the process of global corporate implicating social responsibility activities, the CEO'S ethical values are more important than the transformational leadership of the CEO. Finally, in the relationship between the employees' personal ethical values and personal social responsibility activities, the employees' personal ethical values in South Korean companies have great positive effect on the personal level social responsibility activities.

BACKGROUND/OBJECTIVES: This study examined the relationship between famine exposure in early life and the risk of type 2 diabetes in adulthood during the 1959-1961 Chinese Famine. SUBJECTS/METHODS: A total of 3,418 individuals aged 35-74 years free of diabetes from two studies in 2006 and 2009 were followed up prospectively in 2009 and 2012, respectively. Famine exposure was classified as unexposed (individuals born in 1962-1978), fetal exposed (individuals born in 1959-1961), child exposed (individuals born in 1949-1958), and adolescent/adult exposed (born in 1931-1948). A logistic regression model was used to assess the relationship between famine exposure and diabetes after adjustment for potential covariates. RESULTS: During a three-year follow-up, the age-adjusted incidence rates of type 2 diabetes were 5.7%, 14.5%, 12.7%, and 17.8% in unexposed, fetal-exposed, child-exposed, and adolescent/adult-exposed groups, respectively (P < 0.01). Relative to the unexposed group, the relative risks (95% confidence interval) for diabetes were 2.15 (1.29-3.60), 1.53 (0.93-2.51), and 1.65 (0.75-3.63) in the fetal-exposed, child-exposed, and adolescent/adult-exposed groups, after controlling for potential covariates. The interactions between famine exposure and obesity, education level, and family history of diabetes were not observed, except for the urbanization type. Individuals living in rural areas with fetal and childhood famine exposure were at a higher risk of type 2 diabetes, with relative risks of 8.79 (1.82-42.54) and 2.33 (1.17-4.65), respectively. CONCLUSIONS: These findings indicate that famine exposure in early life is an independent predictor of type 2 diabetes, particularly in women. Early identification and intervention may help prevent diabetes in later life.

In this study, a formula (EJ-F101) was prepared to develop a raw material for acne-prone skin improvement using wheat germ extract, and a clinical trial cream was prepared and clinical trials were conducted. As a result of the analysis, when comparing before and after using the product, both the test group and the control group showed significant improvement effects in terms of open comedones, occluded comedones, papules, sebum and oil content in the facial region at 4 weeks after product use, compared to the control group in the test group which showed a more significant improvement effect. As a result of the survey on the efficacy of the product, most items showed higher positive answers in the test product compared to the control product four weeks after the use of the product, and about 43-81% of the study subjects answered positively in the test product, except for the "open surface" item. In addition, for all items related to the usability of the product, about 14-86% of the test group and 38-90% of the control group answered positively at the time point 4 weeks after using the product. As a result of skin safety evaluation, no adverse skin reactions were observed in all subjects of this study. Based on the above results, it is considered that the cream using wheat germ extract is suitable for use on acne-prone skin(non comedogenicity).

There are differing opinions among scholars as to whether "chuseo" (ugly writing) should be considered as one of the schools in modern calligraphy. Those who do not recognize "chuseo" argue that it lacks traditional rules for stroke formation and therefore loses its distinctiveness. However, the existence and development of "chuseo" are closely related to the constant exploration and reform of modern calligraphy, as well as the increasing aesthetic awareness and changing aesthetic standards of calligraphers with changing times. As a result, there are now more people who recognize "chuseo" as a legitimate form of calligraphy. Calligraphers who lead the times learn and accumulate experiences by adhering to traditional calligraphic principles. However, there are calligraphers who discard the traditional Confucian concept of "chungyong" (中庸) and display "ugliness" in their works. Ok Heung-hwa and Jeung Sang are two such calligraphers who created their own style by incorporating ancient oracle bone inscriptions as their main focus and folk calligraphy as their bloodline. This paper aims to explore and study the definition and formation process of "chuseo" by analyzing the works of Ok Heung-hwa and Jeung Sang. At the same time, it aims to summarize the characteristics and aesthetic beauty of "chuseo".

National parks are one of the important types of protected area management systems established by IUCN and a management model for implementing effective conservation and sustainable use of natural and cultural heritage in countries around the world, and they assume important roles in conservation, scientific research, education, recreation and driving community development. In the context of big data, this study takes China's Liaohe National Park, a typical representative of global coastal wetlands, as a case study, and using Python technology to collect tourists' travelogues and reviews from major OTA websites in China as a source. The text spans from 2015 to 2022 and contains 2998 reviews with 166,588 words in total. The results show that wildlife resources, natural landscape, wetland ecology and the fishing and hunting culture of northern China are fully reflected in the perceptions of visitors to Liaohe National Park; visitors have strong positive feelings toward Liaohe National Park, but there is still much room for improvement in supporting services and facilities, public education and visitor experience and participation.

The third teachings of Confucianism, Buddhism, and Taoism have been coexisted and had effect on the oriental spirits for long times. The doctrines of the Confucianism, the Buddhism, and the Taoism are represented as 'moral culture', 'practice', and "training" respectively. The practices of three teachings had individual ways. But in the late Han-dynasty, they had coexisted and effects on one another, then finally had been united since the Song-dynasty. The Confucianism, which advocated "xiū-jǐ-zhì-rén(修己治人: Practising oneself and controlling others)" and "nèi-shèng-wài-wáng(內聖外王: Establishing natural law in oneself and presenting it to others)", put an emphasis on the practice for personality by "Kŏgzĭ(孔子)" and "Mèngzĭ(孟子)". For example, the practices of "Yăng qi(養氣)", "Jìn Xīn(盡心)", and "Cún Xīn(存心)" reflect this doctrines. In the Song-dynasty, "Zhū-xī(朱熹)" established the 'New Confucianism', the study of "Jū-Jìng-qióng-lĭ'", which put an equality with "human nature" and natural law. It is so-called as "Seong-li-hark" in Korea. Therefore, it came to life again by emphasizing 'jīng-shì: Ruling the world' and "moral culture". The Taoism, which pursued "yán-mìng-cháng-shòu(延命長壽: Maintenance of a Scanty existence long life)" and "dào-tōng-shén-xian"(道通神仙: Spiritual awakening Shén-Xian), originally put an emphasis on the practice of body and mind. For example, "Lăozi(老子)" and "Zhuāngzĭ(莊子)" suggested "bāoyī(包一)", "Shŏuyī(守一)", and "Zuòwàng(坐忘)". After the religious body of the Taoism had been established, "Gè-hóng(葛洪)" accomplished the "Nèidān(內丹)" and "Wàidān(外丹)" as practice methods. As times went over, the "Nèidān(內丹)" of "Yăng-Shēng-Wŭ-Dà-Yāo(養生五大要)" including "bì-gŭ(辟穀)", "fú-qì(服氣)", "dăo-yĭn(導引)", "fáng-zhōng(房中)", and "fú-ěr(服餌)", has been the mainstreams for practice. Since the Song dynasty, "sān-jiào-hé-yī-sī-xiǎng(三敎合一思想: Three Teachings are the each other same thoughts)" had been put on emphasis and the three teachings were effected one another, and all of them attached importance to practical training. Therefore, the practice ways in civil societies have been mixed, the origins of them are difficult to divide definitely. The Korean society also has the vague origins of them and reflects the theses historic traditions.

Fetal growth restriction (FGR) is a prevalent obstetric condition. This study aimed to investigate the role of Toll-like receptor 9 (TLR9) in regulating the inflammatory response and gut microbiota structure in FGR. An FGR animal model was established in rats, and ODN1668 and hydroxychloroquine (HCQ) were administered. Changes in gut microbiota structure were assessed using 16S rRNA sequencing, and fecal microbiota transplantation (FMT) was conducted. HTR-8/Svneo cells were treated with ODN1668 and HCQ to evaluate cell growth. Histopathological analysis was performed, and relative factor levels were measured. The results showed that FGR rats exhibited elevated levels of TLR9 and myeloid differentiating primary response gene 88 (MyD88). In vitro experiments demonstrated that TLR9 inhibited trophoblast cell proliferation and invasion. TLR9 upregulated lipopolysaccharide (LPS), LPS-binding protein (LBP), interleukin (IL)-1β and tumor necrosis factor (TNF)-α while downregulating IL-10. TLR9 activated the TARF3-TBK1-IRF3 signaling pathway. In vivo experiments showed HCQ reduced inflammation in FGR rats, and the relative cytokine expression followed a similar trend to that observed in vitro. TLR9 stimulated neutrophil activation. HCQ in FGR rats resulted in changes in the abundance of Eubacterium_coprostanoligenes_group at the family level and the abundance of Eubacterium_coprostanoligenes_group and Bacteroides at the genus level. TLR9 and associated inflammatory factors were correlated with Bacteroides, Prevotella, Streptococcus, and Prevotellaceae_Ga6A1_group. FMT from FGR rats interfered with the therapeutic effects of HCQ. In conclusion, our findings suggest that TLR9 regulates the inflammatory response and gut microbiota structure in FGR, providing new insights into the pathogenesis of FGR and suggesting potential therapeutic interventions.
