Interferon-tau (IFNT) is known as a major conceptus protein that signals the process of maternal recognition of pregnancy in ruminants. Also, multiple interferon genes exist in cattle, However, molecular mechanisms of these bovine IFNT (bIFNT) genes whose expressions are limited have not been characterized. We and others have observed that expression levels of bovine subtype IFNT genes in the tissues of ruminants; thus, bIFNT1 and other new type I (bIFNTc1/c2/c3) gene co-exist during the early stages of conceptus development and non-trophoblast cells. Its genes transcription could be regulated through CDX2 and ETS2 and JUN and/or cAMP-response element binding protein (CREB)-binding protein (CREBBP) expression, a transcription factor implicated in the control of cell differentiation in the trophectoderm. Bovine ear-derived fibroblast cells, were co-transfected with luciferase reporter constructs carrying upstream (positions -1000 to +51) regions of bIFNT1 and other new type I gene and various transcription factor expression plasmids. Compared to each - 1kb-bIFNT1/c1/c2/c3-Luc increased when this constructs were co-transfected with CDX2, ETS2, JUN and/or CREBBP. Also, Its genes was had very effect on activity by CDX2, either alone or with the other transcription factors, markedly increased luciferase activity. However, the degree of transcriptional activation of the bIFNTc1 gene was not similar to that bIFNT1/c2/c3 gene by expression plasmid. Furthermore, Sequence analyses also revealed that the expression levels of bIFNT1/c2/c3 gene mRNAs expression were highest on day 17, 20 and 22 trophoblast and, Madin-Darby bovine kidney (MDBK), Bovine ear-derived fibroblast (EF), and endometrium (Endo) non-trophoblast cells. But, bIFNTc1 mRNA had not same expression level, bIFNTc1 lowest levels than those of IFNT1/c2/c3 gene in both trophoblast and non-trophoblast cells. These results demonstrate that bovine subtype bIFNT genes display differential, in the trophoblast and non-trophoblast cells.

The objective of this study was to examine measuring agreement between middle phalanx of the third finger and cervical vertebrae analysis for assessing skeletal maturity according to body mass index percentile. A retrospective chart view was used to select patients with body mass index data, hand - wrist radiographs and lateral cephalograms of same day. The patients were divided into 4 groups by body mass index percentile. The hand - wrist radiographs were analyzed using modified middle phalanx of the third finger method and the lateral cephalograms were categorized according to cervical vertebral maturation stage. The degree of agreement between the 2 methods of analyzing skeletal maturation was measured by calculating weighted kappa statistic according to body mass index percentile group. There was a good agreement between the 2 methods in the entire body mass index percentile group. According to the body mass index percentile group, the agreement was found to be different, and the pattern was different between boys and girls. Pediatric dentist should consider sex and weight status when evaluating growing children and adolescents because it can affect the agreement of 2 method of analyzing skeletal maturation.
Through this study, we intend to study user satisfaction in order to verify whether there is a need for full-scale research, development and commercialization of document viewers in a VR environment. VR content consists of realistic 3D graphics and 360-degree video, and provides a synesthesia experience and immersion. We developed and tested a VR document viewer prototype that can utilize this concept as a document viewing system. It can act as a viewer that provides an interactive viewing environment according to the user's body interaction and the direction of the field of view, and it can be said that the feature of VR document viewer is that it can draw the user's high level of immersion and concentration when using the viewer. The developed prototype was tested in a test group consisting of 100 VR experiences and device owners for about 1 hour and 3 days a day, and then a questionnaire survey in the form of a fixed selection question was conducted. This study is a prototype study of a document viewer suitable for a virtual reality environment, and can lead to a sense of immersion when reading a document, and suggest a new document viewer direction that is effective for visual fatigue and visual perception of the document.

Objective: The evidence that hyperbaric oxygen (HBO) therapy is more effective for improving the acute neuropsychological status (ANS) of carbon monoxide poisoning than normobaric oxygen (NBO) therapy is not convincing. This is because the levels of carboxyhemoglobin (COHb) do not correlate with the clinical severity of carbon monoxide poisoning and there is no universally accepted severity scale of carbon monoxide poisoning. This paper suggests a new scale for the clinical and neurological severity of carbon monoxide poisoning, called the ANS, and assesses the effect of HBO therapy for each level of ANS compared to NBO therapy. Methods: A total of 217 patients who had been hospitalized because of carbon monoxide poisoning from January 2009 to July 2013 were studied. ANS was suggested as a new severity scale of carbon monoxide poisoning considered in the Glasgow Coma Scale, acute neuro-psychologic signs and symptoms, or cardiac ischemia on the initial medical contact. HBO therapy is indicated in those who have a loss of consciousness, seizure, coma, abnormal findings on a neurological examination, pregnancy, persistent cardiac ischemia, level of COHb >25%, or severe metabolic acidosis (pH <7.2). The end point is the day of discharge, and recovery is defined as a normal neuro-psychological status without any sequelae. Results: The levels of troponin T and creatinine increased significantly with increasing ANS score. In the moderate to severe group (ANS 2 and 3), the recovery rate was significantly higher when treated with HBO therapy than with NBO therapy (P=0.030). On the other hand, the development of delayed neuro-psychological sequelae (DNS) did not correlate with any level of ANS, type of oxygen therapy, or recovery on discharge. Conclusion: In the moderate to severe poisoned group, HBO therapy is more effective for improving the ANS from carbon monoxide poisoning than NBO therapy. On the other hand, the development of DNS of HBO therapy is no more preventable than with NBO therapy. Although the level of ANS is low, the patient needs to be provided with sufficient information and a follow-up visit is recommended for any abnormal symptoms because the ANS does not correlate with the development and degree of DNS.

Background: Complex regional pain syndrome type I (CRPS-I) consists of disorders caused by spontaneous pain or induced by some stimulus. The objective was to verify the effects of photobiomodulation (PBM) using 830 nm wavelength light at the affected paw and involved spinal cord segments during the warm or acute phase. Methods: Fifty-six mice were randomized into seven groups. Group (G) 1 was the placebo group; G2 and G3 were treated with PBM on the paw in the warm and acute phase, respectively; G4 and G5 treated with PBM on involved spinal cord segments in the warm and acute phase, respectively; G6 and G7 treated with PBM on paw and involved spinal cord segments in the warm and acute phase, respectively. Edema degree, thermal and mechanical hyperalgesia, skin temperature, and functional quality of gait (Sciatic Static Index [SSI] and Sciatic Functional Index [SFI]) were evaluated. Results: Edema was lower in G3 and G7, and these were the only groups to return to baseline values at the end of treatment. For thermal hyperalgesia only G3 and G5 returned to baseline values. Regarding mechanical hyperalgesia, the groups did not show significant differences. Thermography showed increased temperature in all groups on the seventh day. In SSI and SFI assessment, G3 and G7 showed lower values when compared to G1, respectively. Conclusions: PBM irradiation in the acute phase and in the affected paw showed better results in reducing edema, thermal and mechanical hyperalgesia, and in improving gait quality, demonstrating efficacy in treatment of CRPS-I symptoms.

This study is an experimental study to confirm the effect of self-care program on exercise performance self-efficacy, Knowledge of self-management and Performance of self-management in patients with lumbar disc removal. The subjects were 26 inpatients in the experimental group and 27 in the control group as inpatients at the D City Material Spine Hospital. The collected material was analyzed using the SPSS 25.0 program with mean, percentage, standard deviation, t-test, x2-test, Independent t-test, and repeated measures ANOVA. Hypothesis that after self-care program mediation, the experimental group had higher scores for orthosis management knowledge (p<.001) and daily life management knowledge (p=.005) as time passed compared to the unprovided control group. The hypothesis is that the experimental group provided with the self-care program has a performance of orthosis management(p=.011), higher degree of orthosis management performance (p=.011) and daily life management performance (p=.007) than the non-provided control group. Was supported. There, it was confirmed that it is an effective self-care program that can be easily applied at home to patients with lumbar disc removal from the day before surgery to after discharge.
The purpose of this study was to investigate the association factors of dental infection control by applying the health belief model in the dental hygienists. This study subject was 142 dental hygienists from 15 to July 5, 2020. Data were analyzed by chi-square test ANOVA, correlation analysis, and multiple regression analysis using SPSS version 23.0. The performance of dental infection control in accordance with the general characteristics of research subjects was high in case when they had educational experiences of infection control, and when they 'always' did medical examinations by interview about infectious diseases(p<0.01). The group of dental hygienists working for dental clinics with less than average 50 patients a day showed the highest rate of wearing a mask and latex gloves as personal protective gears(p<0.05),(p<0.01). When the wearing of protective goggles(face shield) and the frequency of exchanging masks after the outbreak of COVID-19 were more, the performance for infection control was increasing(p<0.05),(p<0.01),(p<0.001). In this study, it is difficult to generalize the results of the study because the research area and the subject are limited by selecting the subjects by convenience extraction, and focusing on the degree of awareness of infection control by dental hygienists, the actual status of infection control in dentistry is carefully illuminated. What you didn't do can be seen as a limitation. Considering the results of this study, the performance of infection control could be increased by removing obstacles and increasing the importance and perceived benefits of infection control of dental hygienists.

The port of Mokpo operates the largest number of coastal passenger ships and routes in Korea. These coastal passenger ships pass through narrow channels in the south-west coast of Korea owing to the geographical effect. It is difficult to find a research for the safety of the marine traffic environment in the narrow channel used by coastal passenger ship. Therefore, in this study, the navigation safety of the target coastal passenger ship was analyzed in the narrow channel near the port of Mokpo using the Korea design standard for port and harbour facilities. As a result of the analysis, the width of the narrow channel between Maek-island and Dali-island is narrower than 1.5 times of the target ship's length over all, the degree of curvature of the narrow channel exceeds the standard value of 30°, and several fishing gears exist near the narrow channel. Finally, the following were suggested to improve the safety of navigation on the narrow channel: keeping one-way traffic during the day-time, and navigating through the designated fairway during night·visibility restriction·low tide.

In recent years, South Korean has made a globally acknowledged achievement in movie industry. In terms of Art, films produced in South Korea obtained lots of awards in international movie festivals; in the business field, Korean movies are swiftly occupying the Asian or even the world film market. Extraordinary films with good reputations and high box office records are frequently launched and induced to a trend, which then forms into a cultural phenomenon and attributes to an important, major force in the so-called "Hallyu" culture. This, in part, benefits from the massive support of Korean government's cultural policies, and is also a product of the high degree of cultural consciousness of Korean movie producers. The Korean cultures, customs, and the underlying cultural elements of the East, that are presented in these movies, satisfy the audience and appeal their fondness. The Princess and the Matchmaker is a South Korean period romantic comedy film directed by Hong Chang-pyo and starred Shim Eun-kyung and Lee Seung-gi. The movie was presented on Feb 28th, 2018. It tells a story of Seo Do-yoon, the most proficient saju (fortune-teller) expert of the Joseon Era who selected a husband for Princess Song-Hwa based on her "fortune eight letters" (specifically, the time, day, month and year of her and her husbands' birth, normally in eight letters), in a hope of alleviating the rage of people following years of drought, and thus to resolve a national crisis. This paper takes The Princess and the Matchmaker as an example, from the aspects of cultural state, system, behavior and mentality, to analyze the traditional customs such as "fortune eight letters", "marriage by match" and the cultural concepts behind these phenomena, in order to explore the ways and methods of traditional culture in the modern cultural and artistic form of film.
