Objective: To conserve and utilize the genetic resources of a traditional Chinese indigenous pig breed, Liangshan pig, we assessed the genetic diversity, genetic structure, and genetic distance in this study. Methods: We used 50K single nucleotide polymorphism (SNP) chip for SNP detection of 139 individuals in the Liangshan Pig Conservation Farm. Results: The genetically closed conserved population consisted of five overlapping generations, and the total effective content of the population (Ne) was 15. The whole population was divided into five boar families and one non-boar family. Among them, the effective size of each generation subpopulation continuously decreased. However, the proportion of polymorphic markers (P_N) first decreased and then increased. The average genetic distance of these 139 Liangshan pigs was 0.2823±0.0259, and the average genetic distance of the 14 boars was 0.2723±0.0384. Thus, it can be deduced that the genetic distance changed from generation to generation. In the conserved population, 983 runs of homozygosity (ROH) were detected, and the majority of ROH (80%) were within 100 Mb. The inbreeding coefficient calculated based on ROH showed an average value of 0.026 for the whole population. In addition, the inbreeding coefficient of each generation subpopulation initially increased and then decreased. In the pedigree of the whole conserved population, the error rate of paternal information was more than 11.35% while the maternal information was more than 2.13%. Conclusion: This molecular study of the population genetic structure of Liangshan pig showed loss of genetic diversity during the closed cross-generation reproduction process. It is necessary to improve the mating plan or introduce new outside blood to ensure long-term preservation of Liangshan pig.

The Belt with Rhinoceros-Horn Ornaments(known as a seodae in Korean) from the family of Princess Deokon's descendants housed in the National Hangeul Museum underwent emergency treatment for a special exhibition in 2019 upon the request of the National Hangeul Museum. Priority was given to the restoration of the original form of the severely damaged belt and the repair of its detached horn ornaments. Prior to the conservation treatment, researchers conducted a theoretical study of the belt with rhinoceros-horn adornments to learn the names of its structural components and the changes in form that the type experienced by period, thereby establishing a plan for conservation treatment and setting a direction. Among the belts worn by officials from the Joseon dynasty, rhinoceros-horn ornaments were attached to those of officials of the first rank and were considered the most precious behind the king's belt with its jade ornaments. The rhinoceros horn adorning the belt is classified into three categories according to quality. This belt has horn adornments of the highest quality, falling under the "grape design" category with dark brown dots concentrated in the center. The belt has a rectangular shape and lacks a buckle, reflecting a popular form from the nineteenth century. The structure of the belt was identified over the process of conservation treatment, offering information about its method of production. In addition, comparison of the relic with belts with rhinoceros-horn ornaments depicted in Joseon-period portraits of officials allowed the identification of changes in formal features and the detailed structures of belts with rhinoceros-horn ornaments by period. It confirmed that the belt subject to conservation treatment shows the features of belts with rhinoceros-horn ornaments produced in the nineteenth and twentieth centuries.

The purpose of this qualitative study was to identify cultural factors among older Americans that could influence them to accept new welfare technologies. This study also explored how social and cultural-based plans could increase the acceptability of welfare technologies for improving the quality of life of older adults in the future. In-depth interviews were conducted with ten professionals who work with older adults. The collected interview data were subsequently analyzed using a two-cycle open coding process. The data analysis generated 29 codes that were organized into 7 primary codes, or categories, and 22 secondary codes nested within the primary codes. Several themes were identified: individualism, family-oriented culture, pragmatism, low-context culture, privacy, fun-seeking culture, and a less hierarchical culture. These findings will inform the development of a future survey to examine the relationship between older adults' intentions when using technology and socio-cultural factors in community settings. In order to explore the different impact levels of the cultural factors found in this study, the future study will need to include measures for identifying socio-cultural variations among individuals in one country or across countries.

At the age of 15, Song Gyu, the second patriarch of Won Buddhism, met Jeungsan-gyo members and was substantially influenced by them. Jeongsan cultivated himself for three months in Mount Gaya based on their recommendations. He instructed his family members to practice reciting the Tae-eul Mantra. Henceforth, Jeongsan was said to attain supernatural power when he was around 18 years old, and he pursued the traces left by Jeungsan in Jeolla Province. Once there, he asked Jeungsan's younger sister to move to his hometown, Seongju, Gyeongsang Province, and he served her with his utmost sincerity. He went back to the birthplace of Jeungsan and received a Daoist book from Jeungsan's daughter titled, Essentials for an Upright Mind (正心要訣). Jeongsan practiced holy works for 10 months at Daewon-sa Temple in Mount Moak where Jeungsan was said to have attained unification with the Dao. After he had met Jeungsan-gyo members at the temple, he was able to stay in her house where he ended up meeting So Taesan. Before their meeting, it is obvious that Jeongsan was a member of Jeungsan-gyo. Afterward, Jeongsan entered into Won Buddhism and used the passage, 'saving lives by curing the world (濟生醫世).' He recited the writing of Jeungsan, which had been given to his disciples, as if it had been a mantra. In addition, he mentioned Jeungsan's poems or the Chinese poems that he had quoted many times. Jeongsan also interpreted passages from The Hyunmu Scripture (玄武經) written by Jeungsan in a unique manner. Jeongsan answered his disciples in his own way when they asked questions on the teachings of Jeungsan. He recognized Jeungsan as one of the Three Primes, who presided over the Great Opening.

The number of single-parent families in South Korea increased since 2000, related to a sharp rise in the divorce rate of 50s and an increase in male mortality rates among those aged 40s-50s. Middle-aged single mothers experience a critical period realizing self-actualization needs, while being in the middle adulthood from the lifespan developmental perspective. In this respect, it is significant to study self-actualization of middle-aged single mothers through guided imagery and music (GIM) in order to provide them with psychological support. This study was conducted from September 2018 to June 2020, and the GIM sessions were conducted at least 10 times. Four participants were selected among the middle-aged single mothers. The imagery experiences of participants in the GIM sessions were classified into four sub-elements: physicalness, emotion, memory, and sense. Within those sub-elements, eight semantic units were categorized into 46 elements. Finally, 152 semantic units were derived. Moreover, the self-actualization which participants experienced through GIM presented three archetypal images: shadow, persona, and the self. In the GIM sessions, experiences of putting their negative emotions associated with family into words and changing passive self-imagery into active one enabled participants to bring the shadow into their consciousness, there by recognizing their positive and bright internal self. Furthermore, participants could map that their current status as people marginalized by siblings and parents, enraged and holding double standards for others, was suppressed by their 'good daughter' and 'religious' personas. This realization lead them to realize and restore their persona. The use of GIM in the study allowed participants to elicit re-experiences of the negative events, while experiencing various imagery and music. This process helped participants achieve self-actualization.

This article pays attention to the gender representation of an abominable male abject that reveal class polarization in the movie Parasite. I seeks to read a new aspect of emotional politics in which a precariat man becomes a male patriarch while representing himself with an abhorrent position. Parasite shows a reversal of daughter and son responsible for parents, contrary to the existing family narrative. They teaches the parents' generation how to survive neoliberal that their place is created only when they take away others' place. However, after losing this prospect, Ki-woo confesses to his father that he is sorry first. Ki-taek also attempted to identify Dong-ik with the patriarch, but this male solidarity collapsed by class and committed murder in sudden anger. As a result, Gi-taek goes down to the hateful status of a stinking underground life, and Ki-woo receives a message of ethical reflection from his isolated father. The film gives the father and son the noble status of ethical fighter who fought against the structure of class polarization, especially the ending epilogue and narration emphasizing the ethical responsibility and mutual solidarity between father and son. In this process, the voices of female characters are gradually omitted, blurring gender screening for male characters. Parasite reveals the political reenactment strategy of precariat men in the age of neoliberalism, which is ethical subject by claiming to be a class abject himself. And representing the hate with gender-selecting, it is beautifying the responsible ethics of the patriarch.

This study was conducted with the aim of investigating the garden architectural characteristics of Villa d'Este, which occupies a major role in the exploration of the contrasting background, location, and spatial composition characteristics of Italian Renaissance gardens. The survey for the study was divided into a literature survey and a field survey, and the details are as follows. First, in the mid-to-late 16th century, the villa was built under the direction of Cardinal Ippolito d'Este, and afterwards, the ownership of the villa was restored to the Italian government in 1850 due to financial difficulties. The Villa d'Este, which suffered another damage, is now operated with many visitors after going through the restoration process. Second, in the case of location, it has the characteristics of Urbana located in the city center and has valley-type topographical conditions located at the foot of the mountain.Third, in the case of spatial composition, it is orthogonal to the axis, and each part of the garden is developed, influenced by the contrast principles such as the installation of the Cortile del Belvedere and Villa Madama in the early 16th century. The main building is located in the hills so that you can see the garden and the surrounding scenery at a glance. Fourth, among the components, there were stairs, logia, courtyard, and grotto, fountains, cascades, ponds, and vegetation such as laurels, thorn trees.

Yeonjae(淵齋) Song Byeong-seon(宋秉璿, 1836-1905) was the ninth-generation descendant of Uam (尤庵) Song Si-yeol (宋時烈). During his lifetime, he gained the trust of Yu-rim(儒林) and was called to the court several times. However, he eventually refused an official] post and spent his life cultivating his studies in the wild. When the Eulsa Treaty(乙巳條約) was signed on November 17, Yeonjae pleaded with King Gojong about the abolition of the treaty. And on the morning of December 30, Yeon-jae committed suicide at his old house in Hoedeok(懷德). At this time, Yeon-jae sent the final appeal to the king, leaving a message to the king, the people, and Yu-rim about the restoration of national sovereignty, fulfilling his duties as a leader of Sarim(士林). After that, in 1962, Yeonjae was awarded the Order of Independence Medal of National Founding. Song Byeong-seon's excursions took place throughout his life. 22 long and short travelogues are existed today. The excursions were mainly done by land, so most of them rode horses or mules. He sometimes used floats or kilns. But he sometimes knew how to use the waterways effectively. This is because in some travel reports, routes using inland waterways and sea routes appear. The journey of the series continues all the way to finding the relics of his ancestors. In this process, it is clear that he reaffirmed its mission of succession to the family and promised to be a part of the brilliant feat of the ancestors. In addition, the reading of the scriptures and Neo-Confucian discussion were added to the excursions. His excursions continued as a means of publicizing and expanding the Neo-Confucian worldview. Thus, Yeonjae inherited the spirit of John Wangyangi(尊王攘夷) left by his ancestors, and finally raised the banner of Wijeongcheoksa(衛正斥邪) high. And he resolutely set out on the road to death for the country.

The prolyl 3-hydroxylase family member 4 (P3H4), is associated with post-translational modification of fibrillar collagens and aberrantly activated in cancer leading to tumor progression. However, its role in clear cell renal cell carcinoma (ccRCC) is still unknown. Here we reported that P3H4 was highly expressed in renal cancer tissues and significantly positive correlated with poor prognosis. Knockdown of P3H4 inhibited the proliferation, migration and metastasis of renal cancer cells in vitro and in vivo, and also, overexpression of it enhanced the oncogenic process. Mechanistically, P3H4 depletion decreased the levels of GDF15-MMP9 axis and repressed its downstream signaling. Further functional studies revealed that inhibition of GDF15 suppressed renal cancer cell growth and GDF15 recombinant human protein (rhGDF15) supplementation effectively rescued the inhibitory effect induced by P3H4 knockdown. Moreover, decreased levels of MMP9 caused by inhibition of P3H4-GDF15 signaling constrained the expression of PD-L1 and suppression of P3H4 accordingly promoted anti-tumor immunity via stimulating the infiltration of CD4+ and CD8+ T cells in syngeneic mice model. Taken together, our findings firstly demonstrated that P3H4 promotes ccRCC progression by activating GDF15-MMP9-PD-L1 axis and targeting P3H4-GDF15-MMP9 signaling pathway can be a novel strategy of controlling ccRCC malignancy.
