치과 진료는 대부분 인간의 시각에 의존하여 진단과 진료가 이루어진다. 하지만 미세한 치아 손상의 경우 의사가 육안으로 확인하기 어려울 수 있으며, 의사의 실력 및 피로 누적에 의해 조기에 발견을 하지 못할 가능성이 높아진다. 만약 미세한 치아 손상을 조기에 발견하지 못할 경우 시간이 지남에 따라 손상 부위가 커지고, 이를 치료하기 위해 더 큰 비용과 고통이 따르기 때문에 치과에서의 조기 발견이 매우 중요하다. 한편, 인류는 디지털 헬스케어 기술을 개발하여 보다 정확한 진단을 할 수 있게 되었고, 의료 서비스를 효율적으로 제공할 수 있게 되었다. 이에 본 논문에서는 위의 문제를 해결하기 위해 디지털 헬스케어를 사용하여 빅데이터와 딥러닝을 활용한 지능형 전자 루페에 대해 탐구하였다.

본 논문은 Word2Vec를 이용하여 한국어 증상 기반 질병 예측 모델을 제시한다. 아산병원 질환 백과의 크롤링 데이터를 세 가지 형식으로 나누어, 모델에 알맞은 데이터 형식을 찾고 모델에 적용한다. 가장 모델에 맞는 데이터 형식은 증상별 질병과 질병별 증상을 합친 경우이다. 데이터의 양을 늘려 임베딩 스페이스를 넓혔고, 가장 중요한 증상과 질병의 유사도도 정확하게 출력되었다. 이는 유사도가 높은 질병과 증상들이 제대로 학습이 되었다는 것을 알 수 있다. 이렇게 만들어진 예측 모델에 positive 증상을 입력하면 유사도가 향상되고, negative에 입력하면 하락하는 결과를 확인했다. 따라서 환자의 증상을 positive에 넣으면, 그 증상을 가진 질병이 가까워지는 반면, 환자의 증상이 아닌 증상을 negative에 넣으면, 환자에게 맞지 않는 질병이 멀어진다. 그러므로 환자의 상태에 맞는 질병을 유추해, 의사나 환자가 증상에 대한 질병을 알고 싶을 때 또는 검색에 유용하게 사용할 수 있다. 더불어, 질병의 진료과 데이터를 추가하여, 환자에게 맞는 진료과를 찾는 데도 도움을 줄 수 있다.

The objective of this study was to assess the level of contamination of dental equipment surfaces by Staphylococcus aureus and to obtain basic information for the prevention against cross infection between students and outpatients. Human samples were collected by rubbing the oral cavity, anterior noses, and lip of students and outpatients with sterile cotton swabs. Environmental samples were collected from 11 sites at practical laboratory, 4 sites at seminar room, and 5 sites at sterilizing room before, during, and after clinical procedures. These samples were cultured on brain-heart infusion agar at $37^{\circ}C$ for 24 hours. Gram-stained and identified as S. aureus colonies were counted each period and these results were analyzed by t-test and ANOVA test. In human, oral cavity showed the greatest S. aureus counts and there were no statistically significant differences between students and outpatient. Practical laboratory revealed the greatest S. aureus among all environmental groups. The greatest number of S. aureus was observed during clinical procedures (P < 0.05) and light handles, chair head, and spittoon showed a high level of statistically significant differences. In conclusion, S. aureus was dispersed in human and dental clinical environment and increased their number during clinical procedures.

Dentally disabled person means one who have difficulty in cooperating voluntarily with a dentist for routine dental care. Seoul National University Dental Hospital (SNUDH) Dental Clinic for Disabled has worked for them under outpatient anesthesia concept. The aim of this study was to determine the anesthetic characteristics of the patients attending for dental treatment at SNUDH Dental Clinic for Disabled in order to establish better future treatment plans. The data were drawn from the patients who visited SNUDH Dental Clinic for Disabled from January 1999 to October 2002. Total 93 dental treatments for 83 patients were enrolled in this study. Most patients had mental retardation and the conservative treatments were carried out under general anesthesia. Thiopental and vecuronium were mostly used for induction agent and neuromuscular blocker, respectively. Enflurane, with oxygen and nitrous oxide, was mostly used to maintain the anesthesia. Mean total anesthetic time was $164.4{\pm}57.2$ minutes and mean duration at the post-anesthetic care unit was $106.2{\pm}50.5$ min. Serious postoperative complications were not observed. These results showed our successful anesthetic outcomes without any severe side effect or complication and the needs of more outpatient centers for dental care for disabled.

The purpose of this study is to evaluate the service attributes and consumer reactions of telemedicine apps in South Korea and visualize their differentiation by constructing positioning maps. We crawled 23,219 user reviews of 6 major telemedicine apps in Korea from the Google Play store. Topics were derived by BERTopic modeling, and sentiment scores for each topic were calculated through KoBERT sentiment analysis. As a result, five service characteristics in the application attribute category and three in the medical service category were derived. Based on this, a two-dimensional positioning map was constructed through principal component analysis. This study proposes an objective service evaluation method based on text mining, which has implications. In sum, this study combines empirical statistical methods and text mining techniques based on user review texts of telemedicine apps. It presents a system of service attribute elicitation, sentiment analysis, and product positioning. This can serve as an effective way to objectively diagnose the service quality and consumer responses of telemedicine applications.

Recently, a specialized hospital designation system has been introduced. In this regard, it is a question of whether a hospital can be searched by using the term 'specialized hospital' or 'specialized' in Internet online search. In this paper, it was examined whether there is a possibility that the medical institution might be mistaken as a specialized hospital designated by the Ministry of Health and Welfare when the concept of 'specialized hospital' or 'specialized' was used in advertisements. The name specialized hospitals can basically have three general meaning. So, if there is a possibility of confusion or misunderstanding in connection with this general meaning, it may be false advertising. The use of concepts other than these general meanings in law does not mean that general meaning disappears from consumer perception. Therefore, although the concept of a specialized hospital in the medical service act is defined in a special sense, the meaning of the specialized hospital should also be considered according to general recognition. In conclusion, the "Guideline for Specialized Hospital Advertising" prepared by the Ministry of Health and Welfare shows that the establishment of a wide range of prohibition limits the freedom of expression of medical institutions. In addition, the comprehensive prohibition of search terms such as 'specialized', and 'advanced' prevents consumers from freely searching for medical institutions with expertise. These guidelines, which are being deprived of the opportunity for professional medical institutions to advertise themselves appropriately, must be thoroughly reviewed.

As livestock diseases such as foot-and-mouth disease are highly infectious and likely to inflict nationwide damage, it is important to detect such diseases in advance. Infection of foot-and-mouth disease is determined in the field through examination of external symptoms such as rise in body temperature. However, as the disease is carried around initially by travelling veterinarians in some cases, it is critical to measure the body temperature of livestock to detect abnormal temperature pattern early on and transmit temperature reading data remotely to a veterinarian remotely to expedite decision. In this study, we have developed a telemedicine system designed to connect veterinarians and livestock farmers and measure the body temperature of Korean beef cattle with IR sensor module linked to ubiquitous ICT platform as a solution for controlling health conditions of Korean beef cattle and improving the efficiency of livestock farming operations at individual farm, regional, and national level by converging ubiquitous ICT platform and livestock farming practices. Successfully employing the state-of-the-art IT technologies of Korea, the system proposed herein is expected to make Korea's livestock farming industry more sustainable and help the nation to secure technological preeminence in the global livestock products market.

This study studied samples taken off surfaces at three sites (Unit chairs, light handles, cuspidors) of 19 dental hospitals and 28 clinics located in Gyeonggi-do and Incheon, South Korea. The bacterial contamination levels of surfaces were $44.82{\times}10^3CFU/mL$ in cuspidors, higher than in unit chairs ($5.47{\times}10^3CFU/mL$) and light handles ($16.28{\times}10^3CFU/mL$). The values were statistically higher at dental hospitals than at dental clinics, the greater number of patients being associated with the higher bacterial cell count in the cuspidors. The results of identifying the strains isolated purely from surfaces at dental clinic showed Gram positive 47.3% and Gram negative 52.7%. Among Gram positive, the most numberous bacteria were Micrococcus luteus (10.9%), Bacillus pumilus (3.6%), and Staphylococcus aureus (3.6%). Among Gram negative, the most numberous bacteria were Acinetobacter ursingii (5.5%), Brevundimonas diminuta (4.5%), Chryseobacterium (Flavo.) indologenes (CDC IIb) (4.5%), and Methylobacterium sp. (4.5%). This study measures the level of bacterial contamination and identifies the strains isolated in dental clinics. It recognizes the importance of infection control, and the results of the study may be considered as the basis for establishing specific plans for prevention of infection.

There are several unfavorable conditions regarding alveolar bone condition that may compromise the denture patient's satisfaction. Chewing efficiency may not be satisfactory when alveolar bone is deficient, and the denture stability could hardly be achieved when alveolar bone shape is irregular. Implant overdenture can be useful to provide satisfactory denture experience compared to conventional denture. The attachment for implant overdenture can be classified into bar attachment and solitary attachment. When the positions of the implants are in the mandibular anterior region, bar attachment may be favorable to obtain a rigid support of the entire denture. When implants are distributed both on anterior and posterior region, a solitary attachment could be considered for ease of removal and maintenance. This report presents implant overdenture cases with the patients that had unilateral mandibular alveolar bone atrophy conditions. Different abutments were chosen based on the individual patient's mandibular alveolar bone condition and the treatments were successful in terms of patient satisfaction.
