  • The purpose of this study was to investigate the change of tooth mobility and bite force according to periodontal disease severity. Tooth mobility and biting force due to change of viscoelastic property of periodontium were influenced by inflammation of periodontal tissue. 30 patients participated in this study, the periodontal disease severity is evaluated with SBI and attachment loss. SBI and attachment loss were examined by periodontal probe. Tooth mobility was tested two times to each tooth using periotest (Siemens Co, Germany) and bite force was evaluated with MPM-3000 (Nihon Kohden Co, Japan). Statistical analysis was applied to correlation ($r^2$) and regression analysis. The obtained results were as follows : 1. As the attachment loss increased, tooth mobility increased with significance, and they had highly positive correlation ($r^2=0.68$) on entire dentition. 2. As the SBI increased, tooth mobility increased with significance, and they had positive correlation ($r^2=0.37$) on entire dentition. 3. As the attachment loss increased, bite force decreased with significance, and they had highly negative correlation ($r^2=0.42$) on maxillary anterior dentition but low negative correlation ($r^2=0.20$) on the other portion of dentition. 4. As the SBI increased, bite force decreased with significance, and they had highly negative correlation ($r^2=0.31$) on maxillary anterior dentition but low negative correlation ($r^2=0.16$) on the other portion of dentition. 5. As tooth mobility increased, bite force decreased with significance, and they had highly negative correlation ($r^2=0.32$) on maxillary anterior dentition but low negative correlation ($r^2=0.16$) on the other portion of dentition.

  • Objectives: We carried out an observational study of the effects of Nei Guan (P6) and Gong Sun (SP4) acupuncture for the treatment of CINV, preparing for further randomized controlled trial study. This is a case series to explore the changes in the incidence of CINV by acupuncture. Methods: Patients reported a Rhodex index indicating the severity of nausea and vomiting and loss of appetite, before acupuncture, after acupuncture and 1-week follow-up examination. Twelve patients with CINV participated in this study. We included patients receiving chemotherapeutic agents that might induce moderate or severe nausea and vomiting. We conducted 5 treatment sessions with P6 and SP4 acupuncture over the course of 5 days. Results: The median Rhodex score were decreased in 5 patients over time, while we observed loss of appetite of 6 patients were improved over time. During the study, the mean of Rhodex of total patients revealed a decrease of Day 1, Day 7, Day 14; 0.74, 0.68, 0.38, respectively, while the mean of loss of appetite showed a decrease of Day 1, Day 7, Day 14; 5.25, 4.08, 4.00, respectively. Conclusions: The study gives a preliminary data that manual acupuncture of P6 and SP4 may reduce the severity of CINV and loss of appetite, and justifies further study.

  • Objectives: The purpose of this study is to report weight changes and analyze adverse events in diabetic patients with Gamitaeeumjowee-Tang for weight loss. Methods: A retrospective chart review of weight change and adverse events was performed during the 10-week weight loss program using Gamitaeeumjowee-tang with low-calorie diets for diabetics(n=61). Weight and BMI changes were compared before and after the program and calculated the percentage of people who lost more than 5% of their weight, also identified whether subjects felt satiated or not. Adverse events were evaluated in terms of causality, severity and system-organ classes. Results: After 10-week weight loss program, significant weight loss (5.9±2.32kg, 7.73% reduction from baseline) and BMI reduction (2.9±0.86) were reported (n=61). Those who lost more than 5 percent of their body weight accounted for 88.5%, and also 88.5% of the participants felt full to help control their appetite. In assessing the causality of adverse events, 'Unlikely' was the most common (66%) and in severity evaluations, almost all symptoms were mild. Insomnia was the most frequently reported during the first 8 weeks, and constipation was reported the most afterwards. Conclusions: A combination of Gamitaeeumjowee-tang and low-calorie diets for 10 weeks appears to help weight reduction without serious adverse events in diabetic patients. Future well-designed prospective clinical studies testing the effectiveness and safety of this weight loss program are warranted.

  • Objectives: The objective of this study is to evaluate weight change and analyze adverse events in overweight and obese women with polycystic ovary syndrome (PCOS) who were prescribed with Gamitaeeumjowee-tang. Methods: A retrospective chart review was conducted for medical records of patients with PCOS, who were administered with Gamitaeeumjowee-tang for a period of 12 weeks between January 2019 and December 2021. Outcomes were total weight loss/weight loss rate, the percentage of patients who lost more than 5% and 10% of their baseline weight. Adverse events (AEs) reported by patients were evaluated by severity, causality and system-organ classes. Results: A total of sixty-seven patients were included (mean±standard deviation, Age 28.78±5.25 years, weight 76.78±12.84 kg, body mass index 29.2±4.26 kg/m2). The average total weight loss in PCOS patients was 6.57±3.07 kg and the average weight loss rate was 8.55±3.65%. The percentage of patients with more than 5% and 10% weight loss compared to their baseline weight was 86.56% and 25.37% respectively. The analysis of adverse events are as follows: Causality assessment with World Health Organization-Uppsala Monitoring Centre of AEs showed 'Unlikely' was the most common (71.7%) and severity evaluations with Common Terminology Criteria for Adverse Events showed almost all symptoms were mild (98.9%). Conclusions: Gamitaeeumjowee-tang helps to lose weight of PCOS patients, which is overweight or obese, and no serious adverse events have occurred. Additional well-designed clinical studies are recommended.

  • Basel II advanced measurement approaches for operational risk need to estimate the frequency and severity distribution of operational losses. Due to lack of internal loss data, the estimation is impossible in many cases and so external loss data might be used by scaling on asset or gross income. To get around lack of loss data, scenario analysis combined with loss distribution approach can be useful in calculating the capital charge of operational risk. However, scenario based loss distribution approach requires much time and effort. Instead we may apply the analytic hierarchy process to measure operational risk of financial institutions. The analytic hierarchy process combined with loss distribution approach is to estimate the capital charge of operational risk in other areas based on the operational VaR in an area with sufficient loss data. AHP provides a tool for timely measurement of operational risk in this rapidly changing global environment.

  • In FMEA, the risk priority number(RPN) is used for risk evaluation on each failure mode. It is obtained by multiplying three components, i.e., severity, occurrence, and detectability of the corresponding failure mode. Each of the three components are usually determined on the basis of the past experience and technical knowledge. But this approach is not strictly objective in evaluating risk of a given failure mode and thus provide somewhat less scientific measure of risk. Assuming a homogeneous Poisson process for occurrence of the failures and causes, we propose a more scientific approach to evaluation of risk in FMEA. To quantify severity of each failure mode, the mission period is taken into consideration for the system. If the system faces no failure during its mission period, there are no losses. If any failure occurs during its mission period, the losses corresponding to the failure mode incurs. A longer remaining mission period is assumed to incur a larger loss. Detectability of each failure mode is then incorporated into the model assuming an exponential probability law for detection time of each failure cause. Based on the proposed model, an illustrative example and numerical analyses are provided.

  • PURPOSE. This study was designed to investigate the maintenance of teeth and implants in patients with viral liver disease. MATERIALS AND METHODS. 316 patients without any significant systemic disease were selected as a control group. Liver disease group was consisted of 230 patients. Necessary data were collected using clinical records and panoramic radiographs. Then, the patients were subdivided into 2 groups based on the type of active dental therapy received before maintenance period (Pre-Tx). Analysis for finding statistically significant difference was performed based on the need for re-treatment of active dental therapy (Re-Tx) and change in the number of teeth (N-teeth) and implants (N-implants). RESULTS. Comparing to control group, the patients with liver disease showed higher value on N-teeth, N-implants, and Re-Tx. Statistically significant differences were found on N-teeth (P=.000) and Re-Tx (P=.000) in patients with non-surgical Pre-Tx. Analysis based on severity of liver disease showed that N-teeth and Re-Tx were directly related to severity of liver disease regardless of received type of Pre-Tx. Significant differences were found on N-teeth (P=.003) and Re-Tx (P=.044) in patients with non-surgical Pre-Tx. CONCLUSION. In this study, it was concluded that liver disease might influence the loss of teeth and cause the relapse of dental disease during maintenance period in patients. A significant positive relationship between tooth and implant loss and severity of liver disease seems to exist.
