본 논문은 기존의 헬스케어 서비스의 한계를 극복하기 위해 최근 대두되고 있는 스마트 헬스케어 서비스(smart healthcare service)에 관한 연구이다. 스마트 헬스케어는 스마트폰의 기능에 맞추어 기초체력 운동 지수, 섭취 칼로리, 심박 체크 등의 다양한 서비스를 제공할 수 있지만, 최근에는 보건의료서비스에 특화시켜 환자와 의사가 직 간접적으로 진료를 할 수 있게끔 하는 스마트폰 환경에서의 원격진료 서비스가 부각되고 있다. 그러나 헬스케어를 위한 HL7 CDA 표준의 문서 교환방식은 실시간 데이터 획득을 요구하는 원격진료 서비스 환경에 적합하지 못하다. 이에 본 논문에서는 HL7v2.x의 트리거 이벤트를 통한 메시지 전송방식과 HL7 CDA RIM(Reference Information Model)을 응용하는 실시간 HL7 의료정보 전송 방안을 제안한다.

Emergency medical center(EMC) is the place for patients who need medical treatment immediately due to a disease, childbirth, or all sorts of accidents. Currently, most of EMCs use temporary beds because regular EMC beds cannot afford to serve all incoming patients. However, since it decreases the quality of service(QoS) of EMC patients and their guardians and efficiency of the EMC, some improvements are highly required to diminish the usage of temporary beds. The system duration time is one of the typical QoSs. This thesis proposes the information which is critical to make a better decision for cut down the number of temporary beds without sacrificing QoS of patients. The key point is to control the duration time of medical treatments for the consultation and hospitalization process, since it is the major reason of overcrowding in EMC and the usage of temporary beds. In this paper, we proposed an Arena simulation model reflecting real world substantially. Arena is one of the most widely accepted simulation softwares in the world. Using the developed model, we can obtain the optimal EMC operation parameters through simulation experiments. Optquest, included in the Arena, is used to make the developed simulation model collaborate with an optimization model. The results showed one can determine the set of optimal operation parameters decreasing the required number of temporary beds without deteriorating EMC patient's QoS.

The aim of this study was to investigate the change of microbial contamination levels in the different areas and at the different time points after application of a quaternary ammonium compound (QAC) that has mechanical antimicrobial effect. The microbial contamination levels were measured in three different areas; unit chair handle, spit sink area and hand piece holder at different time points using adenosine triphosphate (ATP) monitoring system and ATP surface test kit. Hand piece holder showed the highest level of microbial contamination. In most of the clinics, QAC significantly reduced the levels of microbial contamination, and maintained antimicrobial activity for 4 to 6 months. QAC may be used effectively in dental clinics due to the duration of antimicrobial effect and the minimal exposure of chemicals and further studies are needed with large sample size.

In order to maximize the efficiency and the quality of care in a hospital, hospitals in general operate by appointments. Patient no-shows or missed appointments waste the time of staffs who prepare for appointments, deprive patients of needed care, and increase burden on clinic capacity. The purpose of this study is to examine the importance and significance of factors that affect patient no-shows. The actual data of 50,000 outpatient appointments is compiled and analyzed from a VAMC in the United States with aims to identify the factors that contribute to outpatient no-shows and to draw meaningful implications. Random forest along with logistic regression analysis identify the factors affecting no-shows; appointment leadtime, show-up rate, travel distance, no-show rate in previous period, patient age, severity, complexity of disease, chronic pain, depression, drug dependence. The appointment leadtime, show-up rate, travel distance and previous no-show rate can be improved by enhancing SMS pre-notification and by improving afterwards telephone counseling. For other factors, it needs to study on the service differentiation with the characteristics of each patient group.

This study analyzed the rate of unmet dental care service for the disabled who were judged to require the dentistry due to oral health-related problems and those reasons, and also examined the oral health status according to the unmet dentistry. 375 subjects, who were 19 years or older and completed oral health examination and a survey, among 444 responded positive of disability registration after participation in National Health and Nutrition Examination Survey(NHANES), were analyzed. Disability type was classified into 6 kinds(physical disability, brain lesions, sensory defect, developmental disability, mental disorder, endocrine disorder). Participants had 128 of their dental care needs unmet when it was required. 'Financial burden' was the main reason, with the subject of 49.2%, followed by 'lower on the priority scale' were 18.0%. The high frequency and progression permanent teeth caries experiencs and periodontal status of their dental disease were confirmed. In availability aspect of dentistry resources, it is required for using dentistry service smoothly through providing sufficient proper dental care service comparing with the number of the disabled.

This study targeted 501 the elderly ages 65 or over in three places including the Senior Welfare Center and the college for seniors located in Daegu City and Gyeongsangbuk-do. The study results on the preference for oral health care management items across different ages showed that the age group of 65~69 fluoride application; the age group of 65~74 scaling and education of brushing; the age group of 70~74 denture cleaning and maintenance; the age group of 75 denture production. In the relationship between the self-perceived oral condition and the items of oral health care management, respondents who currently have a poor oral condition or have greater chewing trouble, or have higher dry mouth, preference the manufacturing of dentures in most cases. Respondents who have a lower number of teeth or wear dentures preference dentures cleansing and management in most cases. Respondents who have shaking teeth or have frequent tooth pain preference tooth extraction. Since the preference for oral health care management items may differ by their age or oral condition, oral health management customized to each individual should be applied.

When inflammatory products are found in both periodontal and pulpal tissues simultaneously, a periodontal-endodontic combined lesion is established. The treatment of periodontal-endodontic combined lesions includes root canal therapy and periodontal regenerative procedure for resolution of both the apical and marginal inflammatory lesions. The present study reports the treatment of periodontal-endodontic combined lesions in the mandibular anterior area with root canal therapy, followed by guided tissue regeneration therapy. Teeth with severe bone destruction in each case could be preserved, without extraction, over a 3-year period. Therefore, it appears that treatment of periodontal-endodontic combined lesions in the mandibular anterior area using guided tissue regeneration technique after root canal therapy may provide clinical advantages.
