Purpose: Optical coherence tomography (OCT) has been investigated as a novel diagnostic imaging tool. The utilisation of this equipment has been evaluated through several studies in the field of dentistry. The aim of this preliminary study was to determine through basic experiments the effectiveness of OCT in implant dentistry. Materials and Methods: To assess detection ability, we captured OCT images of implants in each of the following situations: (1) implants covered with mucosae of various thicknesses that were harvested from the mandibles of pigs; (2) implants installed in the mandibles of pigs; and (3) implants with abutments and crowns fixed with temporary cement. The OCT images were captured before cementation, after cementation, and after removing the excess submucosal cement. Results: If the thickness of the mucosa covering the implant body was less than 1 mm, the images of the implants were clearly detected by OCT. In the implants were installed in pigs' mandibles, it was difficult to capture clear images of the implant and alveolar bone in most of the samples. Remnants of excess cement around the implants were visible in most samples that had a mucosa thickness of less than 3 mm. Conclusion: Currently, OCT imaging of implants is limited. Cement remnants at the submucosal area can be detected in some cases, which can be helpful in preventing peri-implant diseases. Still, though there are some restrictions to its application, OCT could have potential as an effective diagnostic instrument in the field of implant dentistry as well.

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS in haste. However, while many older HIS and PACS systems are not yet capable of some of the integration, several new systems are moving rapidly in that direction. Typical PACS system architecture begins with the HIS since this is where the correct patient demographic information and in many cases the orders originate. So, PACS developed convenience of users and to satisfy user's demand because of financial limitations and administrator-oriented considerations in the process of development. Therefore, we have developed a CDA (Clinical Document Architecture) based PACS with HIS, by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. Target model of this research limited to 135 of hospital have 200 beds. We'll make more effort to develop the application which insures the better quality and information of medical images. Medical Image History manages the patient's image files and various medical informations like film chart in connection with time. This trial will contribute to the reduction of the financial loss caused by unnecessary devices and improve the quality in the medical services. The demand on the development of the program which refers to the medical data quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that the program will be modified from the standpoint of the users.

The purpose of this study was to investigate the current status of unmet medical need using data from the Korea Health Panel study from 2009 to 2013 (excluding 2010), and to analyze the trends of unmet medical need and related factors. The subjects of this study were 11,598 in 2009, 11,035 in 2011, 10,584 in 2012, 10,099 in 2013, and 7,144 people in panel data, and conducted frequency analysis, chi-square test and generalized estimating equation. As a result of the analysis by year, it was found that women, under middle school graduation, medical aid, the lowest household income and low subjective health status experienced more unmet medical need. As a result of analysis using generalized estimating equation, women, under 40 years of age, under elementary school graduation, lowest quartile household income, subjective health status of less than 20 points, and activity restrictions are more likely to experience unmet medical need. Based on these results, we intend to provide basic data for establishing policies on the use of medical services.

The number of patients from Middle Eastern Arabic countries is steadily increasing in respect to the South Korean government's medical tourism strategies. Word of mouth is one of the main determinants concerning the Middle Eastern Arab patients' medical tourism destination. Further, patients' satisfaction affects repurchase and revisit intention. This study aimed to measure the level of Middle Eastern Arab patients' satisfaction, and to measure the effect of different medical factors on satisfaction in such patients who are seeking medical attention in South Korea. A 110 Middle Eastern Arab patients who visited South Korea for medical purposes participated in our survey between November, 2016 and April, 2017. All factors had a high mean (${\geq}4.24$; ${\geq}84.8/100$) except for one factor (hospital halal meals (3.82; 76.4)). To identify factors influencing participants' overall satisfaction we used multiple regression analysis. Physicians, interpreters, and halal meals were the main factors influencing overall Middle Eastern Arab patients' satisfaction. Physicians and interpreters in Korea are recommended to be oriented to basic Islamic beliefs and Middle Eastern Arab patients' behavior. Daily communication, such as speaking directly to the patient, limiting important issues to two or three at a time, and translating sentence by sentence, could help to improve Middle Eastern Arab patients' satisfaction. Enlisting Middle Eastern nutrition specialists in medical institutions in South Korea may substantially improve non-medical services satisfaction such as halal food and dietary restrictions.

Background: While the coronavirus disease 2019 (COVID-19) pandemic has affected all aspects of health care, its impact on cardiac surgical practice and outcomes is yet to be determined. We compared the outcomes of our cardiac surgical practice from the past year during the pandemic to those in a similar pre-pandemic period. Methods: Retrospective data were collected from 307 patients who were involved in all adult cardiac surgical procedures performed between March 2020 and February 2021, which was considered the pandemic period, at Amrita Institute of Medical Sciences, India. These were compared with data from the 1-year period between March 2019 and February 2020. During that earlier period, 491 patients underwent surgery, and the surgical outcomes were assessed. Outpatient visit data were also collected to evaluate the effect of COVID-19 on outpatient follow-up visits. Results: A 37% decrease in surgical case volume was observed during the study period. No difference was found in operative mortality between the 2 time periods (3.3% vs. 2.6%, p=0.383). Overall postoperative complications were less frequent during this period, at 23% compared to 38% the previous year (p<0.001). Conclusion: The COVID-19 pandemic caused a dramatic decrease in surgical volume and outpatient medical follow-up. However, the pandemic and its attendant social restrictions did not yield a significant change in the surgical outcomes of our patients. Hence, it is reasonable to continue cardiac surgical care during global health crises, and this can be done with good results.

Excessive gingival display is an esthetic issue that is commonly managed by different procedures. Lip repositioning is a modality to address concerns of affected patients. The aim of this review was to investigate the scientific evidence on outcomes and long-term stability of lip repositioning surgery with or without myotomy. The electronic search was conducted in three databases: MEDLINE, Embase, and the Cochrane Library up to October 2019. No publication status, language, or time restrictions were applied. The electronic search was complemented by a manual search of the reference lists. Three hundred thirty-eight studies were screened by title, and 16 articles remained for data extraction. The included studies assessed the lip repositioning procedure in 144 patients aged between 15-59 years (134 females and 10 males). Based on the available data, lip repositioning with myotomy/muscle containment can be a successful treatment for minor discrepancies in gingival display in selected cases. However, further well-organized controlled clinical trials are recommended to derive a conclusion about the long-term stability compared with other alternatives.

Objectives The purpose of this study was to analyze the Chuna manual therapy usage status after the application of Chuna manual therapy health insurance. Methods This study analyzed the health insurance data (2019-2021). From April 2019 to December 2021, monthly data were collected by simple Chuna, complex Chuna (own expense 50%), complex Chuna (own expense 80%), and special (dislocation) Chuna. Results The major results are as follows. First, in hospital-level medical institutions, simple Chuna and complex Chuna (own expense 50%) occupied a similar proportion. In clinic-level medical institutions, simple Chuna occupies the largest proportion. Second, the amount of use decreased in all medical institutions after September, which is thought to be the result of restrictions on Chuna manual therapy health insurance. Conclusions Therefore, it is necessary to conduct research by receiving more detailed data onr Chuna manual therapy health insurance. Through this, an improved policy of Chuna manual therapy health insurance should be discussed.
