  • This study aims to distinguish what can be used in consideration of the national situation with Korea for Chinese Scenic and Historic Interest Areas, and the results are as follows; First, the Chinese Scenic and Historic Interest Areas expanded to the existing scenic cruise culture, travel, and tourism culture in the process of the influx of Western culture in the modern and contemporary era, and became popular as a travel destination. Accordingly, the Chinese government developed the tourism industry around the scenic sites, and thanks to the development of transportation and communication, the Scenic and Historic Interest Areas has become an important national heritage. This influenced the establishment of the system related to Scenic and Historic Interest Areas, and today, it is operated around the Scenic and Historic Interest Areas ordinance. Second, the designation of the Scenic and Historic Interest Areas is divided into the size of the site according to the area, and the process of selecting the Scenic and Historic Interest Areas classification, rating evaluation, and comprehensive value evaluation according to evaluation indicators and rating standards is carried out. Accordingly, according to the results of the classification, it is subdivided from the national level to the Scenic and Historic Interest Areas at the local level. Third, the central government is in charge of managing and supervising Scenic and Historic Interest Areas across the country, and the local government's construction department is in charge of supervising Scenic and Historic Interest Areas in the region. The management organization of Scenic and Historic Interest Areas established by local governments above the county level has a system that actually protects, utilizes, and manages Scenic and Historic Interest Areas. In addition, 14 detailed indicators are used to monitor Scenic and Historic Interest Areas. Based on these results, considering the application of the domestic scenic site policy, the method of developing the policy that has established the system from the perspective of the utilization of the people is worth considering. On the other hand, the evaluation of the designation and management system through the setting of various indicators has limitations in that it is difficult to secure objectivity in impressing or evaluating the landscape. Therefore, rather than blindly introducing quantified evaluation, it seems that guidance and promotion on how to expand consensus on scenic values and enjoy heritage should be prioritized.

  • Objectives: This study aimed to compare the physical properties and antibacterial effectiveness of iodoform based root filling pastes, Vitapex® and Metapex®, with sodium iodide root filling paste (NaI paste) for primary teeth. Materials and Methods: The physical properties (flowability, film thickness, radiopacity) of the pastes were evaluated according to ISO 6876:2012. The antibacterial activity against Enterococcus faecalis strain (ATCC 6538) was evaluated using a direct contact test. Results: There was no significant statistical difference (p > 0.05) observed in the flow and film thickness of NaI paste when compared to the currently available root canal filling materials. The average flow capacities for Vitapex®, Metapex®, and NaI paste were 15.40 mm, 21.25 mm, and 20.01 mm, respectively. The average film thickness for Vitapex®, Metapex®, and NaI paste were 33.3 ㎕, 22.6 ㎕, and 25.0 ㎕, respectively. However, NaI paste showed lower radiopacity than the existing materials, and this difference was statistically significant (p < 0.05) NaI paste demonstrated higher antimicrobial activity than the available materials, and this difference was also statistically significant (p < 0.05). Conclusion: Compared to the existing commercialized root canal filling materials, NaI paste exhibited similar performance in terms of flow and film thickness, and superior antimicrobial activity against E. faecalis. Hence, NaI paste could be a promising root filling material for primary teeth and may be a potential alternative to existing materials.

  • This study aimed to compare the color stability and surface roughness of three-dimensional (3D) printing resin according to polishing methods. 3D-printed resin specimens were fabricated at TC-80DP (Graphy, Seoul, Korea) with a stereolithography 3D printer, and the specimens were divided into three groups, each of which was not polished, was polished using Enhance®, and was polished using a Sof-LexTM disc. The CIE L*a*b* value and the surface roughness of each group were measured and immersed in artificial saliva and orange juice after 0, 1, 7, 30, and 60 days, and the color difference (ΔE*) was calculated. As a result of the study, no noticeable color change was observed in artificial saliva, but a noticeable color change was demonstrated in orange juice after 60 days of immersion, and the difference was significant. In the Sof-LexTM group, surface roughness according to the solution was found to be significantly higher in the orange juice than that in artificial saliva. No significant difference in color change was found according to the polishing method, but surface roughness was significantly lower in the Sof-LexTM group than both that of the unpolished group and that of the Enhance® group. Nevertheless, all groups exhibited clinically acceptable properties regardless of their higher surface roughness than the threshold for plaque accumulation. Overall, this study recommends utilizing Sof-LexTM for polishing 3D printing resin when used in primary anterior tooth coverage.

  • This study aimed to compare the physical properties of 4 kinds of calcium silicate-based cements (CSCs): 2 kinds of powder-liquid mix type (RetroMTA® [RTMX] and Endocem® MTA Zr [EZMX]) and 2 kinds of premixed type (Well-RootTMPT [WRPR] and Endocem® MTA premixed [ECPR]) CSCs, respectively. Further, we assessed the setting times, solubility values, and compressive strengths of the cements. The shortest setting time was observed for EZMX (123.33 ± 5.77 seconds), followed by RTMX (146.67 ± 5.77 seconds), ECPR (260.00 ± 17.32 seconds), and WRPR (460.00 ± 17.32 seconds), respectively. The highest solubility was observed for WRPR (9.01 ± 0.55%), followed by RTMX (2.17 ± 0.07%), EZMX (0.55 ± 0.03%), and ECPR (0.17 ± 0.03%). Furthermore, the highest compressive strength was observed for ECPR (76.67 ± 25.67 Mpa), followed by WRPR (38.39 ± 7.25 Mpa), RTMX (35.07 ± 5.34 Mpa), and EZMX (4.07 ± 0.60 Mpa). In conclusion, the premixed type CSCs (WRPR and ECPR) exhibited longer setting times compared to the powder-liquid mix type CSCs (EZMX and RTMX). The solubility test showed that ECPR had the lowest solubility while WRPR had the highest solubility, with a statistically significant difference between them (p < 0.0083). Additionally, the compressive strength test showed that ECPR had the highest compressive strength, while EZMX had the lowest compressive strength, also with a statistically significant difference between them (p < 0.0083). ECPR is a promising material as it is premixed, eliminating the need for mixing time, and it has also demonstrated improved solubility and compressive strength, making it a potentially favorable option for clinical use.

  • The aim of this retrospective study was to evaluate the demographic characteristics of pediatric dental patients who underwent dental treatment under general anesthesia (DTGA) at the Seoul National University Dental Hospital from January 2011 through December 2020 and compare the patterns of repeated DTGA between dental patients with severe disabilities (DSD) and non-DSD (healthy or medically compromised patients without DSD). There were 1,857 DTGAs among 1,719 patients (mean age = 5.1 years; males = 59.3%; ASA 2 or above = 52.9%; DSD = 26.8%). Overall, 6.6% of patients underwent repeated DTGA, and the rate of repeated DTGA over a 10-year period was 7.4%. ASA 2 or above (p < 0.0001) and DSD (p < 0.0001) were more likely to undergo repeated DRGA compared to ASA 1 and non-DSD. At both GA1 and GA2, DSD received significantly more restorative treatment on permanent teeth than non-DSD (p = 0.002, p < 0.0001, respectively). There has been an increasing demand for DTGA in pediatric dentistry over the last 10 years. Regular check-ups and preventive oral health care are necessary for pediatric dental patients with severe disabilities to reduce the possibility of repeated DTGA.

  • Clear overlapping of the bilateral epicondyle and proper separation of the elbow joint are crucial for obtaining accurate lateral general radiographs of the elbow. However, due to the complex anatomical structure of the elbow, achieving optimal positioning is challenging, leading to the need for repeated x-ray examinations. Therefore, the purpose of this study was to investigate the angle of the forearm in patients where accurate lateral images of the elbow joint can't be obtained after vertical incidence using a styrofoam device during elbow joint lateral x-ray imaging. Twenty patients were enrolled in our study following the established protocol. First, a vertical x-ray at an angle of 0° between the forearm and the table was taken (control group). Here, if the lateral image of the elbow joint was deemed inadequate, the forearm angle was adjusted using custom-made styrofoam supports with 5° and 10° inclinations (experimental groups). For the evaluation method, two assessors utilized a 5-point Likert scale to assess the images. The reliability of the assessments was analyzed using Cronbach's alpha coefficient. As a result, patients with inadequate overlap of the bilateral epicondyle and separation of the elbow joint in the initial examination (control group) were able to obtain the best images when setting a 10° angle between the forearm and the table. The subjective evaluation was 1.6 ± 0.8 points at 0°, 2.7 ± 0.8 points at 5°, and 4.4 ± 1.3 points at 10°, respectively. The reliability analysis for the angles of 0°, 5°, and 10° yielded Cronbach's alpha values of 0.867, 0.697, and 0.922, respectively. In conclusion, when it is not possible to obtain accurate images using the conventional position and X-ray beam direction, it is considered that by initially acquiring images with an angle of 10° between the forearm and the table, and gradually decreasing the angle while obtaining images, it would be possible to achieve the optimal image while reducing the number of repeat examinations.

  • The cultural contents industries have moved closer to the centre of the economic action in many countries and across much of the world. For this reason, the concern with the development of glocal cultural contents has also been growing. According to Goldman Sock's BRICs report, Indian economy will be the engine of global economy with China. In addition, India will be a new blue chip country for large consumer market of cultual contents. The most important point for the development of glocal cultural contents is a systematic and in-depth analysis of other culture. India is a complex and multicultural country compared with Korea which is a nation-state. Therefore, this paper is intended as an understanding about India appropriately and suggestion for a strategy to enter cultural industry in India. As the purpose of this paper is concerned, we will take a close look at 9 Indian culture codes which can be classified into three main groups: 1) political, social and cultural codes 2) economic codes 3) cultural contents codes. Firstly, political, social and cultural codes are i) consistent democracy and saving common people, ii) authoritarianism which appears an innate respect for authority of India, iii) Collective-individualism which represents collectivist and individualistic tendency, iv) life-religion, v) carpe diem. Secondly, economic culture codes are vi) 1.2billion Indian people's God which represents money and vii) practical purchase which stands for a reasonable choice of buying products. Lastly, viii) Masala movie and ix) happy ending that is the most popular theme of Masala movies are explained in the context of cultural content codes. In conclusion, 3 interesting cases , , will be examined in detail. From what has been discussed above, we suggest oversea expansion strategy based on these case studies. Eventually, what is important is to understand what Indian society is, how Indian society works and what contents Indian prefers.

  • Numerous Researches on the Buddhist perspective of Wonhyo agree that the Mind is the core principle of Wonhyo's Buddihist perspective. Based on prior research, this paper identifies the philosophy of Mind-only(vijñaptimātratā) in the broader perspective, that is, "Mind is the first principle of the existence", as the core thought of Wonhyo. The objective of this paper is to reorganize the systematic theories of consciousness, one of the principle sectors of Wonhyo's philosophy of vijñaptimātratā. One can find most systematic texts of consciousness of Wonhyo in 『GiSilRonSo』 and 『GiSilRonByeolGi』. Although 『GeumGang SamMaeGyeongRon』 includes some interpretations of consciousness, it is difficult to formulate a consistent structure based on it. Beside tā.JangEui』, which discusses the meaning of vijñaptimātratā centering around affliction, Wonhyo's opinion about important issues of vijñaptimātratā philosophy such as ālayavijñāna, permeation, bījadharma, and aspects of perception appears in fragments. Thus, this paper focuses on 『GiSilRonSo』 and 『GiSilRon ByeolGi』, Wonhyo's interpretation of 『Awakening of Mahāyāna Faith』(大乘起信論), as well as 『IJangEui』, 『PanBiRyangRon』 and 『Geum GangSamMaeGyeongRon』. The researcher examines how one-mind, tathāgatagarbha, and ālayavijñāna become the principles of 'neither arising nor ceasing'(不生滅) and 'arising and ceasing'(生滅) of all beings. The process of how one-mind develops mind in terms of the Absolute(心眞如門) and mind in terms of Phenomena(心生滅門) and its ontological structure are also investigated. In addition, the philosophical significance of Wonhyo's interpretation of tathāgatagarbha and ālayavijñāna analyzed. Besides, the method how various theories about vijñāna from Tathāgatagarbha's and Yogācāra's philosophy can be synthesized is examined based on Wonhyo's arguments. The four aspects of existence(caturākāra 四相) -arising(生), abiding(住), changing(異), and ceasing(滅)- which is transformed according to stages and dimensions of 'arising and ceasing', and phases of mind such as delusion of three fine states(三細) and six rough states(六麤), five consciousness(五意), and six defiled states(六染) are interpreted based on Tathāgatagarbha's and Yogācāra's philosophical system.

  • These days, the world finds itself in a time when 21st century human and societal practices can benefit from alternative viable models; as such models are desperately needed. Daesoon Jinrihoe seeks to show one model inspired by the historical kings, Yao and Shun. In Daesoon Jinrihoe, King Yao and King Shun (堯舜 yo sun) are recollected and projected into modern times. This paper is a study that examines what aspects of Daesoon Thought go into understanding Kings Yao and Shun and what insights their example can provide for modern people today. In Daesoon Thought, the 'Dao of Kings Yao and Shun' has appeared again because the 'Era of the Great Opening (開闢時代 gaebyeok shidae)' has arrived, and this era is characterized by 'Seeking Out the Beginning and Returning to the Original Root (原始返本 wonshi banbon).' This is not simply a return to ancient times. The seeds that fall on the ground grow up to overcome winds and rains, bring forth new fruits in the autumn, and their fruits contain the original seeds. The seeds are simultaneously the original seeds, but not the seeds themselves. Rather, they are complete bodies condensed and infused with abundant experience gained after multitudinous trials. In Daesoon Thought, Kings Yao and Shun are analyzed from the following four perspectives: first, as an ideal human image that combines the qualities of Sages and Heroes (聖雄 seong oong), second, as the historical background behind the truth of the 'Resolution of Grievances for Mutual Beneficence (解冤相生),' third, as an ancient model of the ideal world, and fourth, as Daesoon Jinrihoe's 'Mind Dharma (心法)' and also as the classical basis for the 'Cultivation of Dao (修道).' However, the meaning of Kings Yao and Shun in Daesoon Thought is not limited to traditional philosophical thought but also contains certain crucial differences. In Daesoon Thought, the qualities of sages and heroes are combined in a way that does not compromise or penalize, but in accordance with the rule of law and beyond, the ideal world is understood as a world in which there are no natural disasters and everyone enjoys beauty and splendor. Mind Dharma means the spiritual cultivation of the 'Dao of Mutual Beneficence' as presented by Sangje (上帝 the Supreme God) through sincerity, respectfulness, and faithfulness (誠敬信 seong, gyeong, shin). In addition, through the core truth of Daesoon Thought, the Resolution of Grievances for Mutual Beneficence, the resolution of the grudges associated with Kings Yao and Shun will likewise eliminate the root-grudge plaguing humanity and divine beings. In this paper, I intend to deepen my understanding of Daesoon Thought through a study on our theology's understanding of Kings Yao and Shun, and I also wish to redefine the value of Daesoon Thought through the symbolization and reinterpretation of ancient historical figures.
