1. Objectives The purpose of this study was to investigate the concordance rate of the diagnostic results among Sasang Constitutional Medicine(SCM) specialists. 2. Methods We carried out two studies in order to investigate the concordance rate of the diagnostic results between SCM specialists. We calculated the kappa value for analyzing concordance rate(using the SPSS program). 1) Study A : We investigated 142 clients who had taken health examinations and diagnosis of Sasang constitution from March 9, 2005 to March 29, 2005 at a health examination center of Kyung-Hee medical center. Every SCM specialist diagnosed 142 clients directly. Each SCM specialist don’t know the other specialist’s diagnosis. 2) Study B : We investigated 176 clients who had taken health examinations and diagnosis of Sasang constitution from January 2005 to March 2005 at the department of Occupational and Environmental medicine of Kyung-Hee medical center. One SCM specialist diagnosed 176 clients directly and the other specialist knowing previous specialist’s diagnosis, diagnosed each person indirectly 3. Results 1) The concordance rate of the diagnostic results among SCM specialists in study A was relatively high(kappa value=0.700). 2) The concordance rate of the diagnostic results among SCM specialists in study B was high(kappa value=0.895). 4. Conclusions We can confirm the concordance rate of the diagnostic results among SCM specialists is relatively high.

Objectives : The purpose of our investigation is to determine degrees of concordance rate among interpreters. Furthermore, we have examined how much concordance rate to come out when beginners have been compared with the pulse analyzer. Methods : Thirty-nine volunteers were enrolled for this study. These subjects took a 5-minute rest in a sitting position as instructed by the protocol. As they were not allowed to move or speak, radial artery pulse conditions were measured on the lower arm of each subject by means of the pulse analyzer under investigation. Two Korean medical doctors, who did not know the status of default pulse conditions, were also instructed to intuitively choose the most corresponding one in comparison with 13 default pulse conditions. Subsequently, we investigated results between interpreters as well as results between interpreter and pulse analyzer. Results : The total concordance rate, with similar concordance rates being included, between interpreters, between interpreter A and pulse analyzer, and between interpreter B and pulse analyzer was 56.4%, 79.5%, and 71.8% respectively. In faint fine weak pulse(微細弱脈) case, interpreter A and B selected 6 and 7 cases respectively, matched the concordance rate 5, and corresponded separately with the pulse analyzer interpreting 8 cases. Conclusions : In case of skipping pulse 2(促2脈), short pulse(短脈), faint fine weak pulse(微細弱脈), the concordance between interpreters also matches with results drawn from the pulse analyzer. The concordance rate goes higher in proportion with such smaller pulse conditions as faint fine weak pulse(微細弱脈) and short pulse(短脈).

Objectives : The objectives of this study were to investigate the relationship between electrical detection of ear acupuncture points and musculoskeletal pain. Methods : 18 adults who have musculoskeletal pain without trauma factorsparticipated in this study. They answered the questionnaire and their ear acupuncture points were examined with electrical detectors. We analyzed the relationship between electrical detection of ear acupuncture points and musculoskeletal pain with concordance rate and validity. Results : Total concordance rates of the head region was 68.00%(questionnaire) 32.08%(investigation), that of vertebral region was 67.86%, 59.38%, that of both upper limbs was 86.67%, 39.69%, and that of both lower limbs was 50.00%, 23.46%. The true positive rate was 0.704, the true negative rate was 0.492, the false positive rate was 0.508, and the false negative rate was 0.296 in the validity test. In the head, two concordance rates of the temporal and occipital regions were relatively higher than those of the parietal and frontal regions. In the vertebral region, two concordance rates of the cervical and lumbar regions were relatively higher than those of the thoracic and sacrum regions. In the upper limb, two concordance rates of the shoulder and shoulder joints were relatively higher than those of the others. In the lower limb, concordance rates of investigation were relatively low at all areas. The right lower limb was relatively higher than the left in concordance rates of the questionnaire. Conclusions : The results suggest that electrical detection of ear acupuncture points can be used in the diagnosis and treatment of musculoskeletal pain.

Objective: To investigate the concordance of three international guidelines: the Korean Thyroid Association/Korean Society of Thyroid Radiology, American Thyroid Association, and American College of Radiology for thyroid nodules classified by ultrasonography (US) and the diagnostic performance of simulated size criteria for malignant biopsies. Materials and Methods: A total of 2586 thyroid nodules (≥ 1 cm) were collected from two multicenter study datasets. The classifications of the thyroid nodules were based on three different guidelines according to US categories for malignancy risk, and the concordance rate between the different guidelines was calculated for the classified nodules. In addition, the diagnostic performance of criteria related to four different simulated biopsy sizes was evaluated. Results: The concordance rate of nodules classified as high- or intermediate-suspicion was high (84.1-100%), but low-suspicion or mildly-suspicious nodules exhibited relatively low concordance (63.8-83.8%) between the three guidelines. The differences in sensitivity, specificity, and accuracy between the guidelines were 0.7-19.8%, 0-40.9%, and 0.1-30.5%, respectively, when the original biopsy criteria were applied. The differences decreased to 0-5.9%, 0-10.9%, and 0.1-8.2%, respectively, when simulated, similar biopsy size criteria were applied. The unnecessary biopsy rate calculated with the original criteria (0-33.8%), decreased with the simulated biopsy size criteria (0-8.7%). Conclusion: We found a high concordance between the three guidelines for high- or intermediate-suspicion nodules, and the diagnostic performance of the biopsy criteria was approximately equivalent for each simulated size criterion. The difference in diagnostic performance between the three guidelines is mostly influenced by the various size thresholds for biopsies.

Genome-wide association (GWA) studies may benefit from the inclusion of imputed SNPs into their dataset. Due to its predictive nature, the imputation process is typically not perfect. Thus, it would be desirable to develop a scheme for filtering out the imputed SNPs by maximizing the concordance with the observed genotypes. We report such a scheme, which is based on the combination of several parameters that are calculated by PLINK, a popular GWA analysis software program. We imputed the genotypes of 8,842 Korean individuals, based on approximately 2 million SNP genotypes of the CHB＋JPT panel in the International HapMap Project Phase II data, complementing the 352k SNPs in the original Affymetrix 5.0 dataset. A total of 333,418 SNPs were found in both datasets, with a median concordance rate of 98.7%. The concordance rates were calculated at different ranges of parameters, such as the number of proxy SNPs (NPRX), the fraction of successfully imputed individuals (IMPUTED), and the information content (INFO). The poor concordance that was observed at the lower values of the parameters allowed us to develop an optimal combination of the cutoffs (IMPUTED${\geq}$0.9 and INFO${\geq}$0.9). A total of 1,026,596 SNPs passed the cutoff, of which 94,364 were found in both datasets and had 99.4% median concordance. This study illustrates a conservative scheme for filtering imputed SNPs that would be useful in GWA studies.

The purpose of this study was to compare the interpretation results of the panoramic radiographs with those of intraoral radiographs in evaluation of alveolar bone loss. All radiographs were obtained from 100 patients who had visited the Dental Infirmary of Kyungpook National University Hospital for periodontal state evaluation. The results were as follows: The percentages of interpretable sites were 95.9%(94.6% in maxilla, 97.4% in mandible) on the intraoral radiographs, and 90.7%(84.0% in maxilla, 97.3% in mandible) on the panoramic radiographs. The concordance of interpretation scores of marginal bone loss between intraoral and panoramic radiographs was 66.3%(65.6% in maxilla, 66.8% in mandible). And according to the site, the highest concordance was in the distal surface of the mandibular 2nd premolar at 82.0%, and the distal surface of the mandibular 1st premolar(76.8%), the distal surface of the maxillary central incisor(75.8%), the mesial surface of the 2nd premolar (75.0%) in descending order of frequency. According to the interpretation scores of the marginal bone loss, the percentages of concordance between intraoral and panoramic radiographs were the highest on the score 10 at 76.4%, and the lowest on the score 8, 9. And the percentages of concordance were inverse proportional rate from the score 5 to the score 9. Number of the observed sites of the furcation involvement in bitewing and panoramic radiographs were 268 sites, and the percentage of interpretable sites was 92.9% in bitewing radiographs and 86.6% in panoramic radiographs. And the concordance rate of interpretation was 79.5%.

Purpose: This study was to evaluate usefulness of $^{99m}Tc$-MIBI scintimammography for dense breast by comparing concordance in test results between Tc-99m MIBI scintimammography and mammography whose effect was proved the most as an imaging tool depending on breast density and at the same time by examining limitation on evaluation depending on density of breast tissue. [Materials and Methods] In the period from December 2010 to July 2011, this study targeted 150 patients who took both of $^{99m}Tc$-MIBI scintimammography and mammography conducted by using breast gamma camera in this hospital. Breast density was classified to the four levels of pattern 1~4 based on the results of mammography. $^{99m}Tc$-MIBI scintimammography was conducted with the LCC, the RCC, the LMLO, and the RML one minute after intravenous injection of 99mTc-MIBI 7400 MBq (20 mCi) while analysis was made for concordance in test results of $^{99m}Tc$-MIBI scintimammography and mammography. [Results] Among the 150 patients, pattern 1 was found in 3 patients, pattern 2 in 44 patients, pattern 3 in 61 patients, and pattern 4 in 37 patients. There were 5 patients who showed the case where it was impossible to determine density of breast tissue due to foreign body inserted to breast. The concordance ratio of the results between $^{99m}Tc$-MIBI scintimammography and mammography was 95.5% for pattern 2, 95.1% for pattern 3 and 94.6% for pattern 4. This demonstrated that the concordance rate decreased according to the increase in breast density. [Conclusion] When there was limitation on evaluation of breast specific gamma imaging test results due to increased intake in breast tissue or surgical site, the concordance rate was 6.8% for pattern 2, 16.3% for pattern 3 and 18.9% for pattern 4. This demonstrated that the degree of limitation on evaluation of breast specific gamma imaging test results increased according to the increase in breast density.
