Introduction The clinical usefulness of Sasang Digestive Function Inventory (SDFI) for analyzing Sasang type-specific pathophysiological symptom was illustrated repeatedly. It was revised to enhance its validity, reliability and clinical usefulness, however its clinical studies supporting these were not sufficient yet. Methods 193 healthy university students responded once to Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), and Dutch Eating Behavior Questionnaire (DEBQ), and twice to SDFI with four weeks of interval. The Body Mass Index (BMI) and Ponderal Index (PI) were also calculated. The 4-week test-retest reliability and correlation coefficients between NDIK, FDQOL, DEBQ, and SDFI were examined using Pearson's correlation. The significant differences between Sasang types in SDFI and its subscales were examined using ANCOVA with the age as covariate. Results The range of test-retest reliability for SDFI and its subscales was from 0.801 to 0.887. The SDFI-total correlated positively with BMI (r=0.323) and DEBQ-External Eating (r=0.433), while the SDFI-Digestion negatively with NDIK (r=-0.472) and FDQOL-total (r=-0.364). The SDFI-Habit correlated positively with BMI (r=0.310) and DEBQ-total (r=0.481), and the SDFI-Appetite with DEBQ-total (r=0.322). The SDFI-total, SDFI-Digestion, and SDFI-Habit scores of Tae-Eum type (35.6±6.25, 12.38±3.24 and 9.89±3.38, respectively) were significantly bigger than those of So-Eum type (29.84±8.31, 9.93±4.28 and 7.66±3.96). Discussion The SDFI was found to be an objective clinical measure with sufficient concurrent validity for measuring eating behavior and quality of life related to overeating and dyspepsia, and illustrated distinctive differences between Sasang types. It might be useful for the effective medical education and integrative medical practice.

The purpose of this study is to help preschool children in the interface design of educational game APP at the psychological level. The conceptual model is constructed through the Technology Acceptance Model (TAM) to explore the perceived usefulness and perceived ease of use when children are playing educational game APP. The empirical study was conducted in the form of questionnaires collected after children used game. The research subjects were 3-6 years old children, and the research tool was the game app. Data collection under the guidance of their parents. The research shows that children educational game experience elements can effectively increase preschool children's psychological perception of educational games. Perceived ease of use also increases trust in educational games for children. The results were as follows: 1. Cronbach's Alpha and KMO were 0.969 and 0.955, and the P value was significant, which passed the reliability and validity test. 2. Through confirmatory factor analysis (Model fit index, Composite reliability, discriminant validity), we found that user experience is closely related to perceived usefulness and perceived ease of use. 3. The path analysis of the relationship proves that perceived ease of use play a key role in trusting preschool children educational game APP.

The purpose of this study was to develop generalized validity evaluation indexes for the Sasang type diagnostic test. As a generalized evaluation index for Sasang type diagnostic test, Generalized Squared Correlation (GC2), Mutual Information (I) and Mutual Information Coefficient (IC) as overall validity index, and Correlation Coefficient (C) and Mutual Information Contribution (ID) as type-specific validity index were suggested and the practicability of these indexes was assessed along with Percentage Correctly Predicted (PCP), adjusted PCP, type-specific sensitivity and type-specific specificity which was proposed previously. The usefulness of the nine validity indexes was examined using previously reported data and three mock Sasang type diagnosis results. We demonstrated here that the PCP is not adequate for the analysis of validity. We also showed that our validity index is recommendable for the comparison and improvement of Sasang type diagnosis. The generalized validity analysis of Sasang type diagnosis can provide a guideline for the development of new Sasang type diagnosis or pattern identification. The working sheet for calculating validity indexes can be acquired at http://www.sasangtypology.org/validity.

Purpose: The purpose was to assess the usefulness of midazolam in patients undergoing minor oral surgery under conscious sedation. Materials and methods: Bispectral index was examined in 20 patients receiving oral minor surgery with conscious sedation supplemented with local anesthesia. All patients included were ASA I and had no contraindications to the study medications. The patients were escorted to the day surgery operation room where, before the commencement of the sedation and surgical procedures, routine monitoring was applied, including the noninvasive monitoring of arterial blood pressure, arterial oxygen saturation, and 3-lead electrocardiogram (Electrocardiogram). Bispectral index electrodes were applied on the frontotemporal region after cleansing the skin with alcohol. Bispectral index was calculated with the Electrocardiogram monitor (A-2000; Aspect Co.). Midazolam was then titrated (initially 3mg wait 2min and 2mg). Vital sign and Bispectral index checked every 5 minute until the end of the procedure. The results were then compared. Results: The Bispectral index index values throughout the sedation study period alter many level. The index was dropped at 5 minutes after administration, but raised at injection and odontomy procedure. During the operation, mean Bispectral index index was higher than conscious sedation index range($60{\sim}80$). The amnesic effect was shown 17 cases out of 20 cases(85%). Conclusion: Conscious sedation technique using midazolma is a safe and effective method of controlling behavior in oral and maxillofacial surgery.

Purpose: The management of hemorrhagic shock is critical for trauma patients. To assess hemorrhagic shock, the clinician commonly uses a change in positional blood pressure, the shock index, an estimate of the diameter of inferior vena cava based on sonography, and an evaluation of hypoperfusion complex shown on a CT scan. To add the finding for the hypoperfusion complex, the 'halo sign' was introduced recently. To our knowledge, this 'halo sign' has not been evaluated for its clinical usefulness, so we designed this study to evaluate its usefulness and to find the useful CT signs for hypoperfusion complex. Methods: The study was done from January 2007 to May 2007. All medical records and CT images of 124 patients with trauma were reviewed, of which 103 patients were included. Exclusion criteria was as follows: 1) age < 15 year old and 2) head trauma score of AIS ${\geq}$ 5. Results: The value of kappa, to assess the inter-observer agreement, was 0.51 (p < 0.001). The variables of the halo-sign-positive group were statistically different from those of the halo-sign-negative group. The rate of transfusion for the halo-sign-positive group was about 10 times higher than that of the halo-sign-negative group and the rate of mortality was about 6 times higher. Conclusion: In the setting of trauma, early abdominal CT can show diffuse abnormalities due to hypoperfusion complex. Recognition of these signs is important in order to prevent an unwanted outcome in hemorrhagic shock. We conclude that the halo sign is a useful one for hypoperfusion complex and that it is useful for assessing the degree of hemorrhagic shock.
