The dragon is a special imaginary figure created by the people of East Asia. Its archetypes appeared primarily as totemic symbols of different tribes and groups in the region. The formation of early dynasties probably generated the molding of the dragon symbol. Dragon symbols carried deep imprints of nature. They concealed alternative messages of how ancient people at different locations dealt with or interacted with nature. Under pressure to standardize in the medieval and late imperial periods, the popular dragon had to transform physically and ideologically. It became imposed, unified, and framed, conveying ideas of caste classification and power, and losing itsecological implications. The dragon transitioned from a semi-ecological domain into a total social caste system. However, many people considered the "standardized" dragon as the symbol of the oppressor. Because of continuous orthopraxy and calls for imperial reverence, especially under orthopractic agenda and the surveillance of local elites, the popularized dragon was imbued within local artworks or hidden under the sanctity of Buddhas or popular gods in order to survive. Through disguise, the popular dragon partially maintained its ecological narratives. When the imperial dynasties ended in East Asia (1910 in Korea, 1911 in China, 1945 in Vietnam), the dragon was dramatically decentralized. However, trends of re-standardization and re-centralization have emerged recently in China, as the country rises in the global arena. In this newly-emerging "re-orthopraxy", the dragon has been superimposed with a more externally political discourse ("soft power" in international relations) rather than the old-style standardization for internal centralization in the late imperial period. In the contemporary world, science and technology have advanced humanity's ability to improve the world; however, it seems that people have abused science and technology to control nature, consequently damaging the environment (pollution, global warming, etc.). The dragon symbol needs to be re-defined, "re-molded", re-evaluated and reinterpreted accordingly, especially under the newly-emerging lens-the New Confucian "anthropocosmic" view.
With the development of AI and digital technologies such as big data, metaverse, and the Internet of Things, Robotic Process Automation (RPA) has brought great development and change to companies. Among these realistic industrial areas by RPA, the call center service area, which consists of a combination of complex high-tech systems and professional operation groups, has now reached the stage where AI is conducting counseling. The evolution of this digital transformation has become an important direction of change in the digital-related industry sector. Along with these changes, there have been many changes in the technical stress of the members of the organization within the RPA organization and their solutions. In this study, the representative psychological mechanisms were presented as Digital Shadow Work (DSW), expressed as 'unpaid work', and Organizational Citizenship Behavior (OCB), which is 'an act that helps organizations other than their duties'. This study theoretically contributes to the extension of the DSW concept to the organizational members.
Purpose: This study was to determine the protective effects of Dioscoreae Rhizoma on the Mouse Embrio Fibroblast (MEF) cells exposed to the ultraviolet rays(UVA). Methods: The samples were assigned randomly to five groups; control group without any treatments, UVA group exposed only to UVA, DR group exposed only to the Dioscoreae Rhizoma, UVA-DR group exposed to UVA before being treated with the Dioscoreae Rhizoma, and DR-UVA group treated with the Dioscoreae Rhizoma before being exposed to UVA. The survival rate of cells, metabolic rate of cells, transformation of nucleus within cells, alteration of cell cycle, effects on the apoptosis, the change of the amount of protein related to cell cycle were measured in order to determine the cell protective effects of the Dioscoreae Rhizoma on each group. Results: 1. DR-UVA group has more cell protective effects compared to the UVA group in all experiments, indicating that the Dioscoreae Rhizoma protects skin from UVA physically and chemically. 2. UVA-DR group shows more efficiency compared to UVA group in rapid recovery of damaged cell and leading highly damaged cells to apoptosis, preventing the expression of abnormal cells. Conclusions: Dioscoreae Rhizoma has effects of protecting MEF cells from UVA, of recovering cells damaged by UVA, and of prohibiting the expression of abnormal cells.
Objective: This study aimed to compare the mechanical and thermal properties in the anterior and posterior segments of new and retrieved specimens of a commercially available multizone superelastic nickel-titanium (NiTi) archwire. Methods: The following groups of 0.016 × 0.022-inch Bioforce NiTi archwires were compared: a) anterior and b) posterior segments of new specimens and c) anterior and d) posterior segments of retrieved specimens. Six specimens were evaluated in each group, by three-point bending and bend and free recovery tests. Bending moduli (Eb) were calculated. Furthermore, the new specimens were evaluated with scanning electron microscopy/energy-dispersive X-ray spectrometry. A multiple linear regression model with a random intercept at the wire level was applied for data analysis. Results: The forces in the posterior segments or new specimens were higher than those recorded in the anterior segments or retrieved specimens, respectively. Accordingly, Eb also varied. Higher austenite start and austenite finish (Af) temperatures were recorded in the anterior segments. No statistically significant differences were found for these temperatures between retrieved and new wires. The mean elemental composition was (weight percentage): Ni, 52.6 ± 0.5; Ti, 47.4 ± 0.5. Conclusions: The existence of multiple force zones was confirmed in new and retrieved Bioforce archwires. The retrieved archwires demonstrated lower forces during the initial stages of deactivation in three-point bending tests, compared with new specimens. The Af temperature of these archwires may lie higher than the regular intraoral temperature. Even at 2 mm deflections, the forces recorded from these archwires may lie beyond biologically safe limits.

Background: International evidence shows that mining workers are at greater risk of suicide than other workers; however, it is not known whether this applies to the Australian mining sector. Methods: Using data from the National Coronial Information System, rates of suicide among male mining workers were compared to those of three comparators: construction workers, mining and construction workers combined, and all other workers. Age-standardized suicide rates were calculated for 2001-2019 and across three intervals '2001-2006', '2007-2011', and '2012-2019'. Incidence rate ratios for suicide were calculated to compare incidence rates for mining workers, to those of the three comparative groups. Results: The suicide rate for male mining workers in Australia was estimated to be between 11 and 25 per 100,000 (likely closer to 25 per 100,000) over the period of 2001-2019. There was also evidence that the suicide rate among mining workers is increasing, and the suicide rate among mining workers for the period 2012-2019 was significantly higher than the other worker group. Conclusions: Based on available data, we tentatively deduce that suicide mortality among male mining workers is of concern. More information is needed on both industry and occupation of suicide decedents in order to better assess whether, and the extent to which, mining workers (and other industries and occupations) are at increased risk of suicide.
Mathematical modeling activities hold the potential for diverse applications, involving the transformation of real-life situations into mathematical models to facilitate problem-solving. In order to assess the cognitive, affective, and social dimensions of students' engagement in mathematical modeling activities, this study conducted sessions with ten groups of fifth-grade elementary school students. The ensuing processes and outcomes were thoroughly analyzed. As a result, each group effectively applied mathematical concepts and principles in creating mathematical models and gathering essential information to address real-world tasks. This led to notable shifts in interest, enhanced mathematical proficiency, and altered attitudes towards mathematics, all while promoting increased collaboration and communication among group members. Based on these analytical findings, the study offers valuable pedagogical insights and practical guidance for effectively implementing mathematical modeling activities.

Background: An immunological approach for aging mechanism appears to be important. Lymphocyte subsets analysis in peripheral blood is widely performed to assess the immune status and to diagnose and monitor various diseases. Some lymphocyte subsets are known to change with age, but only few data about age-related reference ragnes for these subsets in healthy individuals have been reported. So we attempted to report reference ranges for these subsets in each age group and review changes of the results with age for the secondary studies about immune cell function as lymphocyte blast transformation and immunoglobulin gene rearrangement (VDJ) including recombination activating genes (RAG-1 and RAG-2). Methods: Lymphocyte subset analysis was performed on 302 subjects, 189 males and 113 females with age group of all decades of life. Two color direct immunofluorescene flow cytometry (FCM) was done using $Simultest^{TM}$ IMK-Lymphocyte kit (Becton Dickinson, USA), $FACScan^{TM}$ (Becton Dickinson, USA) and $FACSCalibur^{TM}$ (Becton Dickinson, USA). Lymphocyte subsets analysed were T ($CD3^+$) and B cells ($CD19^+$), helper/inducer T ($CD4^+$) and suppressor/cytotoxic T cells ($CD8^+$), helper/suppressor ($CD4^+/CD8^+$) ratio and natural killer (NK) cells ($CD3^-CD16^+/CD56^+$). The absolute numbers of each subset were calculated from total lymphocyte counts. Data collected was analysed using SAS 6.12. A P-value of < 0.05 was considered significant. Results: We reported the counts and percentages of lymphocyte and these subsets in each age group. There were no statistically significant differences between male and female subjects. The percentage of $CD4^+$ T cells, and the count of NK cells did not show the significant difference among the various age groups. The age-related changes observed in our study were as following: 1) a decrease in the percentages of T cells, B cells and $CD8^+$ T cells ; 2) a decrease in the counts of B cells and $CD8^+$ T cells ; 3) an increase in the percentage and count of NK cells ; and 4) an increase in the $CD4^+/CD8^+$ ratio. Conclusion: The characteristics of aging process appeared to be showing a marked decrease of lympocyte subsets T and B cells as well as T8 ($CD8^+$). The age-related increase of the percentage of cells bearing NK marker can be interpreted as a compensatory consequence to cope with the decrease of T cells related to the thymic involution. These changes with age appeared to be for the secondary study about immune cell function as lymphocyte blast transformation and immunoglobulin gene rearrangement.

Background: Inverted papilloma(IP) of the nasal cavity and paranasal sinuses is a benign neoplastic condition that can be associated with squamous cell carcinoma (SCC). Several studies have indicated an etiologic role for viruses in the development of inverted papilloma. And it is necessary to find out the significance of a biologic markers such as p53, c-erbB-2 to predict the malignant potential. The purposes of this study are to detect HPV in inverted papilloma of the nasal cavity and paranasal sinus, to examine role of HPV as an etiological agent, to examine the relationship between HPV subtype and malignant transformation of inverted papilloma, and to investigate the relation between expression rate of p53, c-erbB-2 and HPV in recurrent or malignant transformation cases. Material and Methods: Thirty two cases of inverted papilloma(IP) in the nasal cavity and paranasal sinuses were reviewed and classified into 3 groups; simple IP, IP with dysplasia group, IP with squamous cell carcinoma group. Paraffin embedded achival tissue was used in this study. The HPV was detected by in situ hybridzation (ISH) using HPV type 6/11, 16/18, 31/33/35 DNA probes. Expression of p53 and c-erbB-2 was examined by immunohistochemical staining. Results: 1) The HPV was detected in 6(19%) out of 32 cases. 2) The HPV 6/11 was dectected in 4 out of 21 cases of simple IP, HPV 16/18 in 1, HPV 31/33/35 in lout of 8 cases of IP with dysplasia respectively. 3) The positive expression of p53 was 13 cases out of 32 cases; 2 out of 21 cases of simple IP, all of 8 cases of IP with dysplasia and 3 cases of IP with squamous cell carcinoma 4) The positive expression of c-erbB-2 was in 24 out of 32 cases; 16 out of 21 cases of simple IP, 6 out of 8 cases of IP with dysplasia, 2 out of 3 cases of IP with squamous cell ca. 5) The recurrence of IP occurred in lout of 6 cases of positive for HPV, in 4 out of 26 cases negative for HPV. 6) The recurrence of IP occurred only in positive cases for p53. 7) The recurrence of IP occurred in 4(17%) out of 24 cases positive for c-erbB-2, in 1(13%) out of 8 cases negative for c-erbB-2. Conclusion: The p53 expression was associated with Inverted papillomas exhibiting evidence of malignant transformation. Also, there was a correlation between the p53 expression and recurrence.
This paper examines whether the dynamic and practical nature of Daoism has a significant relationship with the messianic figure Kang Jeungsan (姜甑山) via Honam (湖南) Daoism's Jinindaemangron (眞人待望論, discourse on awaiting an immortal). To this end, the historical implementation of Daoism's social transformation of consciousness in China and Korea is explored, and then the circumstances of Honam Daoism, in particular, are considered. Following that, analysis turns to the 'Jinindaemangron' in the late Joseon Dynasty that developed in Honam. As a result of the discussion, Daoism's social transformation of consciousness was expressed in China through the anti-establishment activities of the early Daoist groups such as Wudoumidao (五斗米道) and Taipingdao (太平道), movements that sought to build utopias. Throughout this process, the term, zhenren (眞人, 'jinin' in Korean), that originally meant 'master,' was transformed into the idea of a future savior. In the case of Korea, the dynamic and practical nature of Daoism can be found in the preface of Nanrang tombstone (鸞郎碑序) written by Choi Chi-won (崔致遠) which was later inherited by the Danhak sect (丹學派) practitioners who struggled against Buddhist monastics. Additionally, examined is the Docham theory of geomancy (圖讖說) that rose after Goryeo, the prophecy of 'Mokjadeuksul (木子得國說 a Lee clansman shall attain the kingdom)' that appeared thereafter, and the Prophecies of Jeong Gam (鄭鑑錄)'s 'Jinindaemangron' in the Joseon Dynasty. Next, the circumstances of Honam Daoism can be considered with regards ti Choi Chi-won and Doseon (道詵) in ancient times, and it can be confirmed that Nam Gung-du (南宮斗) and Kwon Geuk-jung (權克中) were entangled behind Kang Jeungsan. The close relationship among the Daoist Jeong family of Onyang (溫陽鄭氏), the Koh family of Jangheung (長興 高氏), and Kwon Geuk-jung was also confirmed in this study. Finally, in dealing with the 'Jinindaemangron' of Honam in the late Joseon Dynasty and the birth of Kang Jeungsan, Honam Daoism's intense consciousness of social transformation receives first focus, and this is expressed through Prophecies of Jeong Gam, and the religious ideologies of Donghak (東學) and Namhak (南學). These expressions are analyzed through Song of Gungeul (弓乙歌), composed by Jeongryeom (鄭磏), and through Daesoon Jinrihoe's The Canonical Scripture (典經). As a result, it can be confirmed that the messianic significance of the Kang Jeungsan's advent lay on the basis of the people's desire for an ideal future, which is a notion that had been ripening for several centuries.

To improve the productivity of the earthwork, a fleet management system for construction equipment was suggested in previous studies. But there were some gaps between theory and practice. To overcome this problem, some opinions are gathered form experts and field engineers and four improvements have been proposed and reflected in the system. First, the previous system consists of one hardware module, so it is hard to install it at a control office and construction equipment at the same time. The server module for the office and the mobile module for construction equipment are separately developed. Second, the transportation algorithm that is used in the previous system can generate shortest paths for the earthwork distribution, but embankment areas are not gathered. This situation leads to a decrease in compaction productivity. A modified algorithm for earthwork distribution is suggested. Third, the automated coordinate transformation is performed to show the position of construction equipment on the 3D terrain in real-time. Fourth, construction equipment groups should be formed in the initial stage of earthwork and the number of equipment of each groups should be changed by operation status and site environment. But this functions did not work properly in the previous system. This problem is corrected in the proposed system. The improvements can make the proposed system much more realistic one and can leads to an increase in the productivity of earthwork operations.
