  • Purpose: This study aimed to assess the usefulness of machine learning and automation techniques to match pairs of panoramic radiographs for personal identification. Materials and Methods: Two hundred panoramic radiographs from 100 patients (50 males and 50 females) were randomly selected from a private radiological service database. Initially, 14 linear and angular measurements of the radiographs were made by an expert. Eight ratio indices derived from the original measurements were applied to a statistical algorithm to match radiographs from the same patients, simulating a semi-automated personal identification process. Subsequently, measurements were automatically generated using a deep neural network for image recognition, simulating a fully automated personal identification process. Results: Approximately 85% of the radiographs were correctly matched by the automated personal identification process. In a limited number of cases, the image recognition algorithm identified 2 potential matches for the same individual. No statistically significant differences were found between measurements performed by the expert on panoramic radiographs from the same patients. Conclusion: Personal identification might be performed with the aid of image recognition algorithms and machine learning techniques. This approach will likely facilitate the complex task of personal identification by performing an initial screening of radiographs and matching ante-mortem and post-mortem images from the same individuals.

  • This study explores the effects of facemasks on respiratory, thermoregulatory, cardiovascular responses during exercise on a treadmill and at rest. Five male subjects (25.8 ± 0.8 y, 171.8 ± 9.2 cm in height, 79.8 ± 28.1 kg in weight) participated in the following five experimental conditions: no mask, KF80, KF94, KF99, and N95. Inhalation resistance was ranked as KF80 < KF94 < N95 < KF99 and dead space inside a mask was ranked as KF80 = KF94 < N95 < KF99. The surface area covered by a mask was on average 1.1% of the total body surface area. The results showed no significant differences in body core temperature, oxygen consumption (VO2), carbon dioxide production (VCO2), heart rate or subjective perception among the five experimental conditions; however, cheek temperature, respiratory ventilation and blood pressure were greater for KF80 or KF94 conditions when compared to KF99 or N95 conditions (p<0.05). The differences among mask conditions are attributed to the dead space or specific designs (cup type vs pleats type) rather than the filtration level. In addition, the results suggest that improving mask design can help mitigate respiratory resistance from increased filtration.

  • Background: Benzalkonium chloride (BKC) has been extensively used as a preservative in industrial products and in hygiene, medical, and cosmetic applications. Humidifier disinfectant (HD) products containing BKC have been used in South Korea. Objectives: This study was aimed to review types of products containing BKC, to summarize the regulations in the US, EU, Japan, and South Korea, and to review the health effects associated with the use of HD. Methods: We reviewed and summarized documents which were searched through PubMed and Google Scholar with the key words: BKC and asthma/contact dermatitis, humidifier disinfectant-associated lung injury (HDLI), and more. Results: Regulations in most countries including South Korea do not allow its use as disinfectants in spray-type of products for medicine, cosmetics, and household products. Two types of HD containing BKC (800~1,270 ppm) were marketed in South Korea from 1996~2003. Health effects reported from people who used products containing BKC were allergic contact dermatitis, erythema, and respiratory disease, including asthma. Two people who responded as HD users containing BKC only were confirmed to have developed asthma. HD-associated lung injury (HDLI) was reported by consumers who used both HD containing polyhexamethylene guanidine (PHMG) and HD containing BKC. Conclusions: In conclusion, the use of BKC as a biocide has to be controlled considering the route and pattern of exposure. Products containing BKC as preservatives were reviewed with exposure routes and sites in the human body such as skin, eyes, and the respiratory tract. HD containing BKC was clinically evaluated to be associated with asthma.

  • Background and objective: There are many theories related to the development of agrotourism, and each stakeholder has its own role and function. If it is based on organizational functions, stakeholders need to be coordinated, and the state plays a major administrative role. But in the successful case of Yeongdong County, Chungcheongbuk province, the Republic of Korea, the government played an important role in the development of tourism, which grants us another perspective on the role of the government in promotion and development agrotourism activities. Methods: This article aims to examine the development of agrotourism through a cooperative approach, by clarifying the role of the local authorities in the Yeongdong region in the management and operation of the local agrotourism activities. The qualitative research method is based on a field survey conducted in Yeongdong County in 2019. Results: The study's findings show that in situations where conflicts of interest among stakeholders are prone to occur, the development of local tourism has a limited impact on the cooperative culture, and local governments play an important role. Accordingly, the local governments must actively formulate strategies to maintain and develop traditional agricultural industries and at the same time develop agrotourism activities. The government's ability to coordinate, cooperate, and participate reasonably is a key factor for the success of the sustainable development of the tourism industry. Conclusion: Based on coordination between stakeholders and a reasonable strategic direction, Yeongdong's agrotourism is being effectively deployed. The development of Yeongdong's agrotourism industry has achieved impressive results through an effective strategy, highlighting the important role of localgovernment in the consensus of local communities and collaboration with stakeholders. The role of outstanding local governments has been clearly demonstrated, especially in promoting, establishing, and contacting different organizations to effectively deploy agrotourism in the region.

  • 'In-Jon(人尊)' is one of a concept which constitute the mainstay of Daesoon thought. To be superficial, the concept is appeared to be limited at a area of anthropology, but In-Jon is a large concept which includes ontology and epistemology. Because the essence of human being is connected with God and the such possibility is related to the mission of human being's subject who exists in world. Advanced researches to analysis of in-jon tend to focus on rise of human status but this study do on universal subject not particular subject. This is to elaborate the point of issue. The point of view as rise of human status overlooks problem of relationship between human entities. who ingenerate hierarchy. In-jon is the universal subject of philosophical subject concepts which western philosophy have taken as main problem since Descartes. So we have to consider In-jon to be conceptual continuity concerning stream of history of ideas and communicate with ideas. A precedent study on 'injon' concept has weak conceptual analysis, which only emphasizes the greatness of mankind as compared with others. But that can't reveal In-jon based on the Daesoon thought. So I try to engraft the concept on development of subject ideas to get academic objectivity. In-jon is great in having universal subject to expand the authority of God to all creation. That is the last goal which subject can reaches through the development. Considering this regard the research direction of this study is very encouraging and significant. Western philosophy has important philosopher of the three, Descartes, Kant, Hegel. Those are a spectrum who show an aspect of subject ideas. The subject idea has become the middle of philosophical system since Descartes in modern. It is the right and necessary process to philosophy because human being has spirit or reason connected with God. So In-jon in Daesoon thought is academic concept comprising ontological and epistemological properties. So I try to analyse In-jon through that and have In-jon join the ranks of mainstream academics in this paper

  • This study aims at exploring the transnational care for family members back home among the Nepalese marriage immigrant women in Korea on the bases of some transnational care practices like remittances, virtual intimacy through information and communication technologies, visit to Nepal, and invitation of family members to Korea. This study argues that in order to understand migrant women's care practices properly, Nepalese marriage immigrant women should be considered as 'being in-between' the societies and cultures of Nepal and Korea. This study identifies the characteristics of transnational care practices of Nepalese women are closely related to the role expectation for the eldest daughter as well as whether or not migrant women have children, jobs, and original family member in Korea. Furthermore, this study highlights that migrant women's transnational care practices should be considered as 'reciprocal exchange of cares' between marriage women and their family members rather than one-way benefits going to the latter.

  • The purpose of this article is to examine the conflicts and political implications of the various linguistic practices concerning how to call old age, and to illuminate the reasons for these conflicts in the cultural sphere. Recently, the issue of proper ways of calling old age has become problematized. As a result, new ways of addressing older people are being devised, which signifies the marginalization of old age. These new ways of calling older people, however, are not settling the problems. It is because the ageist, gender-discriminatory, status-conscious culture of Korea marginalizes the meaning of the various ways of calling old age. As the otherization of old age deepens in the cultural realm, old age becomes a site where various features of marginality accumulate. The academy and the professionals need to be aware of the political implications of the various ways of calling old age, and to strive to surmount discriminatory linguistic practices.

  • Conrad's novels, specifically the Lingard Trilogy-Almayer's Folly, An Outcast of the Islands, and The Rescue-and Lord Jim, set in the Southeast Asian or Malay Archipelago can be considered travel literature that played a significant role in British imperial expansion. Conrad's Malay novels were based not only on his experience in the region during his commercial journey but also on information from earlier travel writings about the Malays and their customs, including James Brooke's journals. The English traders in Conrad's novels, namely Lingard and Jim, were partly modeled on Brooke, the White Rajah, who founded and ruled the English colony on the northwest of Borneo in the 1840s. The white traders in Conrad's novels, who act as enlightened rulers, represent the British commercial expansionism, which was obscured by the phenomenon of the civilizing mission in the late nineteenth century. On the other hand, the colonial official Clifford's tales and novels about British Malaya demonstrate the typical travel accounts of the late nineteenth century that stress the civilizing mission over commercial exploitation. The concept of the enlightening mission was rooted in evolutionary anthropological thinking, which developed as part of the natural history in the early nineteenth century. In fact, the development of natural history, stimulating British expansion in search of commercially exploitable resources and lands, enabled travel writing as the collection of natural knowledge to become a profitable business. In Conrad, the white characters are mainly traders acting as colonial rulers, while in Clifford, they are scientific rulers with their commercial interests rarely apparent. In sum, Conrad's novels reveal that the new imperialism of the civilizing mission is still a commercial one, which disturbs rather than contributes to the imperial expansion-in contrast to other travel literature such as Clifford's.

  • In the late nineteenth century, British colonial activities became aggressive and annexationist in the tropics, including the Southeast Asian Archipelago, which reflected the historical circumstances of both increasing resistance from the indigenous and severe competition among European powers. Interestingly, the change in English colonial policy toward an annexationist or imperialist vision adopted the motto of a civilizing mission, which was founded on the anthropological assumption that the white English were civilized, while the non-white indigenous were savage. The assumption developed into colonial discourse through systematic gathering of anthropological knowledge about the peripheries of the Empire. The knowledge system was flawed, which stressed the differences of the peripheral populations from the English and served as an inverted discourse on the Imperial Self rather than the description of the Other. Furthermore, the natives were heterogeneous, which rendered indistinct the racial and cultural differences between the English and the natives. Still, the aboriginals called Malays, who were comprised of many ethnic subgroups, needed to be deemed savage or inferior by the English in order to justify the English civilizing work or imperial ambition. Put differently, the representation of the English as civilized necessitated the (mis)representation of the natives as savage. In this context, Clifford's works contribute to systematic misrepresentation of the Malays, on which colonial discourse is founded, though not without self-contradiction. On the other hand, Conrad's novels that are set in the Malay Archipelago resort to a strategic misrepresentation that reveals the relativity of the discourse. Exploring the dilemma of denationalization to various degrees, Conrad's Malay texts problematize the (mis)representation of the indigenous as inferior, which is the basis of English claim to superiority.

  • Flourishing in the Central Dry Zone of Burma during a period from the mid-eleventh to the late-thirteenth century A.D., the historical kingdom of Pagan was one of the major Buddhist centers in Southeast Asia. The significance of Pagan as an important pilgrimage site of the region, where numerous relics of the Buddha were enshrined, had been maintained until long after the fall of its civilization. It is evident that the artistic influences of Pagan, particularly in the architectural and decorative domains, had been transmitted to various other Buddhist civilizations in the area. This study provides a detailed analysis on the relationships between the mural tradition of Pagan and those of its neighboring civilizations in Thailand-of the Ayutthayā, Lānnā and Sukhothai schools-dating from after the Pagan Period in the fourteenth century to the sixteenth century. Surprisingly, as the analysis of this study has suggested, such relationships seemed to be trivial, more on a minor stylistic basis than on substantial ideological and iconographic grounds. They suggest that transmission of the complex idea and superb craftsmanship of the mural tradition would not have been maintained adequately at Pagan after its civilization, probably due to the lack of royal patronage. It would have been extremely difficult for foreign pilgrims who visited Pagan after its dynastic period to appreciate the surviving murals of this lost tradition in terms of their complex programs and associated symbolism. Also, there had been a new center of the Sinhalese Buddhism firmly established in the Martaban area of lower Burma since the mid-fourteenth century that outcompeted Pagan in terms of supplying the new Buddhist ideas and tradition. Its fame spread wide and far among the Buddhist communities of Southeast Asia. Later, these Buddhist communities also established direct contact with Sri Lanka. The Sukhothai murals and the Ayutthayā murals in the crypt of Wat Rātchaburana, dating from the fourteenth/fifteenth century, show obvious Sri Lankan influence in terms of artistic style and Buddhist iconography. They could be a product of these new religious movements, truly active in Southeast Asia during that time.
