1. Objective : This study aimed to know the concordance coefficient and diagnostic trend of 6 Sasang constitution diagnosis factors among experts, which are important to diagnose Sasang constitution. 2. Methods : We suggested each 100 cases containing body shape, face, temperament, physiological and pathological symptom and constitutional drug response to 2 groups experts, and researched expert opinions. We analyzed concordance coefficient with Kendall's coefficient of concordance W. 3. Results : 1) Experts agreed with 167(82.5%) diagnosis results of cases, but there were 33 cases(17.5%), with which even one expert disagreed 2) The concordance of priority order of Sasang constitutional factors was significantly associated within expert. 3) Experts put the priority concordance to drug response and Face, body shape, voice and Pathological and physiological symptoms in order. 4) In case by case, concordance coefficient was 47(55.9%) in group 1, 9(10.8%) in group 2, 56 (33.5%) in total. 4. Conclusions : Experts made much account of drug responses and faces in diagnosing Sasang constitution. but there were different opinions in concordance coefficient. So Sasang Constitution Diagnosis Guideline is necessary to integrate experts opinions.

Baker proved that any strongly quasi-positive fibered knot is minimal with respect to the ribbon concordance among fibered knots in the three-sphere. By applying Rapaport's conjecture, which has been solved by Kochloukova, we can check that any strongly quasi-positive fibered knot is minimal with respect to the ribbon concordance among all knots in the three-sphere. In this short note, we give an alternative proof for the fact by utilizing the knot Floer homology.

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.

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).

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.

In the study of homology cobordisms, knot concordance and link concordance, the following technical problem arises frequently: let ${\pi}$ be a group and let M ${\rightarrow}$ N be a homomorphism between projective $\mathbb{Z}[{\pi}]$-modules such that $\mathbb{Z}_p\;{\otimes}_{\mathbb{Z}[{\pi}]}M{\rightarrow}\mathbb{Z}_p{\otimes}_{\mathbb{Z}[{\pi}]}\;N$ is injective; for which other right $\mathbb{Z}[{\pi}]$-modules V is the induced map $V{\otimes}_{\mathbb{Z}[{\pi}]}\;M{\rightarrow}\;V{\otimes}_{\mathbb{Z}[{\pi}]}\;N$ also injective? Our main theorem gives a new criterion which combines and generalizes many previous results.

혈관 질환 위험인자의 가족력은 이미 잘 알려져 있으며 최근 심혈관 질환의 위험인자를 대상으로 한 연구에서는 가족력 뿐 만 아니라 배우자간의 위험인자 일치성이 있다고 밝혔다. 이는 혈관 질환 위험인자에서의 가족력은 유전적인 이유뿐 만이 아니라 환경적 요인으로 인해서도 발생한 다는 것을 암시한다. 그러나 뇌졸중이 발생한 환자에서 그 배우자간 위험인자의 일치성을 알아본 연구는 없었다. 이 연구는 본 연구를 진행하기 앞서 시행한 연구로서 뇌졸중으로 입원했던 환자를 대상으로 위험인자간의 관련성을 조사해 그 경향성을 파악하고자 하였는데 고혈압의 유무(p=0.025)와 경동맥 내막-중막 두께(r=0.479, p=0.001)에서 의미있는 연관성을 보였으나 나이를 보정하는 경우 의미가 없는 것으로 드러났다. 일반 인구 대상이거나 심혈관질환자가 대상이었던 종전의 연구 결과와는 다른 결과였다. 의미 있는 경향성을 보인 위험인자에 대해서 추후 보다 큰 규모의 연구가 필요할 것이다.

This study investigates the relationship between stock index and its associated nearby futures markets based on the cost-of-carry model. The purpose of this study is to explore the existence of mispriced futures contracts, and to test whether traders can earn trading profits in real financial market using the information about the mispriced futures contracts. This study suggests the concordance correlation coefficient to investigate the existence of mispriced futures contracts. The concordance correlation coefficient gives a desirable result for trading profits that results from a comparative analysis among profits from trading at the time to indicate trading opportunities determined by the degree of the difference between the observed market price and the theoretical price of a futures contract. In addition, this study also explains that the concordance correlation coefficient developed from the mean square error (MSE) has a statistically theoretical meaning. In conclusion, this study shows that the concordance correlation coefficient is appropriate for analyzing the relationship between the observed stock index futures market price and the theoretical stock index futures price derived from the cost-of-carry model.

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.
