The variation in resource utilization for hospitalized patients who had a group of similar diseases -- a Korean Diagnosis Related Group (KDRG) -- among the same type of hospitals was studied to assess the utillization variation due to the practice pattern of hospitals. Information about inpatients who were beneficiaries of the medical insurance for teachers and government officials discharged from 20 large university teaching hospitals in Seoul during 1986 and information about the hospitals were analyzed to achieve the study objective. A total of 20,223 non-outlier patients in 100 most frequent KDRGs were included in the analysis. Case charges after the review and length of stay (LOS) were used as measures of resource utilization during a hospitalization. A substantial variation among hospitals was found in most KDRGs : o the ratio of the maximum and the minimum among the mean case charges of hospitals was greater than 2 in 83 KDRGs ; o the difference between the maximum and the minimum among the mean case charges of hospitals was greater than 100,000 Won in 94 KDRGs : o the ratio of the maximum and the minimum among the mom LOS of hospitals was greater than 2 in 82 KDRGs ; o the difference between the maximum and the minimum among the mean LOS of hospitals was greater than 3 days in 94 KDRGs. The practice pattern of hospitals explained more than 20% of charge variation in 49 KDRGs and more than 20% of LOS variation in 43 KDRGs. The study results indicated need for a new health policy initiative for cost containment and quality assurance.

Objectives: The purpose of this study was to analyze the medical cost of facial paralysis in payer perspective and to estimate the practice pattern of patient using 2011 Health Insurance Review & Assessment Service-National Patients Sample(HIRA-NPS). Methods: Basic statistical system was used for descriptive analysis of NPS dataset. A table for general information (table20) was extracted by disease code, and social demographic characteristics, distribution of the use among inpatients and outpatients, utilization of each kind of medical care institutions, medical cost were analyzed. Subgroup analysis was conducted for assuming the practice pattern of korean medicine and western medicine. Results: A total of 8,219 people and 64,345 claims data were identified as having facial paralysis. Proportion of outpatient was 95.23%, inpatient 0.84% and patient using both services 3.93%. Mean patient charges was 44,229 won per outpatient, 178,886 won per inpatient and 523,542 won per patient using both services. Utilization of korean medical care institutions was 68.81%(claims), 40.46%(patients), utilization of western medical care institutions was 31.19%(claims), 59.54%(patients). The amount charged by korean medical care institutions was 52.61% and western medical care institutions was 47.39%. Cost per claim was higher than those of the korean treatment and cost per patient of western treatment was lower than those of the korean treatment. Conclusions: The research assessed the medical cost and practice pattern associated with facial paralysis. These findings could be used in health care policy and subsequent studies.

This study compared levels of health beliefs and health behavior practices according to lifestyle pattern among adults in Seoul. A self-administered survey questionnaire was collected from a total of 1,004 Seoul residents aged 30-59 years. The levels of perceived benefit, perceived barrier, and self-efficacy from health belief model and health behavior practices were measured across multiple health behavior areas including dietary behavior, drinking, smoking, exercise, functional food consumption, and weight control behavior. Factor analysis and subsequent cluster analysis based on 28 lifestyle questions divided the subjects into four lifestyles of society-, economy-, trend-, and health-oriented lifestyle. Some general characteristics were significantly different by lifestyles. The society-oriented lifestyle was significantly higher in proportions of men and overweight. The trend-oriented lifestyle was significantly younger and spent more monthly allowance. Health-oriented lifestyle was older. The levels of health belief variables and health behavior practices significantly differed by lifestyles. Overall the health-oriented lifestyle showed more desirable levels of health belief variables and health behavior practice in various health behavior areas compared to the other lifestyles, whereas the society-oriented lifestyle was found the other way. Health belief model variables including perceived benefit, perceived barrier, and self-efficacy were generally significant in predicting the levels of various health behavior practice, with somewhat differences by lifestyle pattern and health behavior type. The study findings suggest it may be useful to segment target subjects according to lifestyle pattern in planning and administering health education programs.

In this paper, this app is an online learning tool web application that helps learners learn efficiently. It discusses how learners can improve their learning efficiency in these three aspects: retrieval practice, systematization, metacognition. Through this web service, learners can proceed with learning with a flash card-based retrieval practice. In this case, a method of managing a flash card in a form similar to a directory-file system using a composite pattern is described. Learners can systematically organize their knowledge by converting flash cards into a mind map. The color of the mind map varies according to the learner's learning progress, and learners can easily recognize what they know and what they do not know through color. In this case, it is proposed to build a deep learning model to improve the accuracy of an algorithm for determining and predicting learning progress.

Objectives: This study was aimed to develop a Korean Medicine (KM) clinical practice guideline (CPG) of Nausea and Vomiting of Pregnancy (NVP). Methods: We conducted a questionnaire survey targeting KM doctors belonging to the Association of Korean Medicine by e-mail. We received 1,023 responds, and analyzed the answers. Results: 1. 83.0% of respondents knew the concepts and contents of CPG, and 98.1% had practical use plan. 2. 82.1% of respondents used pattern identification diagnosis for NVP patients, and the most commonly diagnosed pattern was spleen-stomach weakness (脾胃虛弱) with 41.3%. 3. The most frequently used treatment for NVP patients was KM combined treatment (46.7%). Herbal medicine+acupuncture (46.8%) was most used among KM combined treatments, and herbal medicine (37.1%) was most used among KM single treatments. 4. Among the contents of CPG for NVP, the fields of interest were selected in the order of KM treatment, KM-Western medicine cooperative treatment, KM diagnosis, prevention and regimen management. In the 'diagnosis part', the use of the symptom evaluation scale questionnaire was 41.8%, higher than the KM pattern diagnosis (34.4%). In the 'treatment part', herbal medicine accounted for 33.8%, higher than that of acupuncture (including electro-acupuncture) at 23.7%. 5. As for the expected development effects, opinions on evidence-based, safety, clinical use, and standardization were the most common. Conclusions: We figured out KM doctors' recognition of KM clinical practice guideline, clinical diagnosis, treatment on NVP to make the contents of the CPG reflecting the clinical situation.

The practice pattern of pediatric dentistry has been changing for the last several decades. This change might be influenced by several factors such as development in dental materials and socioeconomic changes. The purpose of this study was to analyze the changing trends of patient distribution and treatment pattern of pediatric dentistry. Patient distribution and practice trends from 2006 to 2015 at the department of pediatric dentistry of Seoul National University Dental Hospital were reviewed. From 2006 to 2015, the proportion of new patient increased from 12.49% to 20.56%. The average age of new patients decreased. In 2006, restorative treatment had highest percentage, followed by preventive treatment, orthodontic treatment, surgical treatment, and pulp treatment. In 2015, preventive treatment had highest percentage, followed by restorative treatment, orthodontic treatment, surgical treatment and pulp treatment Frequency of general anesthesia increased more than 5 times for last 10 years. The proportion of insurance treatment decreased until 2009, and after 2010 it increased steadily.

A normal range of motion is essential for performing activities of daily living. The capsular pattern is the proportional motion restriction in range of motion during passive exercises due to tightness of the joint capsule. Although the capsular pattern is widely referred to in clinical practice, there is no scientific evidence to support the concept. In this review, the appropriateness of the capsular pattern for evaluation of joint pathology was assessed. In the Textbook of Orthopaedic Medicine written by Cyriax, the capsular pattern did not specify how much reduction in angular motion is considered motion restriction. As the definition proposed initially was unclear, different methods have been used in previous studies investigating capsular pattern. In addition, the capsular pattern described all the major joints of the human body, but only the hip joint, knee joint, and shoulder joint were studied in experimental studies. Sensitivity and specificity were reported in one study and were meaningful in specific pathologies (loss of extension to loss of flexion). There was no consensus on the reliability and validity. In summary, the capsular pattern suggested by Cyriax or Kaltenborn is not supported or applies only to certain conditions. Various components around a joint complement each other and provide stability to the joint. It is recommended that the therapist perform multiple assessments rather than rely on a single assessment when evaluating joints.

The aim of this study was to explore the effects of a computerized review program which was introduced in August 1, 2003, using claims data for acute respiratory infection related diseases. National Health Insurance (NHI) claims data on respiratory infection related diseases before and after the introduction, with six month intervals respectively, were used for the analysis. Clinic was the unit of observation, and clinics with only one physician whose specialty was internal medicine, pediatrics, otorhinolaryngology and family medicine and clinics with a general practitioner were selected. The final sample had 7,637 clinics in total. Indices used to measure practice pattern was prescription rates of antibiotics, prescription rates of injection drug per visit, treatment costs per claim, and total costs per claim. Changes in the number of claims for major disease categories and upcoding index for disease categories were used to measure claiming behavior. Data were analysed using descriptive analysis, t-test for indices changes before and after the introduction, analysis of variance (ANOVA) for practice pattern change for major disease categories, and multiple regression analysis to identify whether new system influenced on provider' practice patterns or not. Prescription of antibiotics, prescription rates of injection drug, treatment costs per claim, and total costs per claim decreased significantly. Results from multiple regression analysis showed that a computerized review system had effects on all the indices measuring behavior. Introduction of the new system had the spillover effects on the provider's behavior in the related disease categories in addition to the effects in the target diseases, but the magnitude of the effects were bigger among the target diseases. Rates of claims for computerized review over total claims for respiratory diseases significantly decreased after the introduction of a computerized review system and rates of claims for non target diseases increased, which was also statistically significant. Distribution of the number of claims by disease categories after the introduction of a computerized review system changed so as to increase the costs per claims. Analysis of upcoding index showed index for 'other acute lower respiratory infection (J20-22)', which was included in the review target, decreased and 'otitis media (H65, H66)', which was not included in the review target, increase. Factors affecting provider's practice patterns should be taken into consideration when policies on claims review method and behavior changes. It is critical to include strategies to decrease the variations among providers.

Pediatric dentistry is differentiated from other fields of dentistry in that it provides comprehensive dental care for children and adolescents. In early days, pediatric dentistry used to be confined to the caries treatment and extraction of primary teeth However, the practice spectrum of pediatric dentistry has broadened to the orthodontic, surgical, esthetic and preventive treatments A survey that contained questions about practice patterns were mailed to 50 pediatric dentists, and 21 surveys were returned. Results were as follows: 1. The average number of patients per week was 82.4, and the average number of treated teeth per patient was 2.35. 2. Preventive treatments comprised 15.7%, restorative treatments 55.7%, endodontic treatments 15.6%, surgical treatments 10.5%, and orthodontic treatments 2.4%. 3. In restorative treatments, amalgam restoration comprised 3.8%, glass ionomer 5.5%, composite resin 63.0%, and stainless steel crown 27.7%.
