본 연구는 한국춤의 논리적 이해를 돕는 춤이론과 훈련법에 대한 방법론적 연구를 위한 것으로, 대상자는 본 연구의 대상 춤인 태극구조 기본춤의 고안자로부터 직접 사사(師事)를 받은 무용수로서 태극구조 기본춤의 호흡을 가장 잘 이해하고 수행할 수 있는 무용수를 대상으로 하였으며, 호흡분석에 따른 호흡표기의 타당성을 검정하기 위하여 호흡패턴을 측정할 수 있는 써미스트(Thermister)가 장착된 마스크와 휴대용 가스분석기(Meta max3B, 독일)를 등에 착용하고 태극구조 기본춤의 12단계 중 2단계에 해당하는 무용동작들을 3회반복하게 하여 이때의 호흡을 측정하여 호흡패턴을 분석하였다. 본 연구의 결과는 일치백분율은 평균값이 84.5%, 최소값은 75.6% 최대값은 95.1%로 나타났으며, Kappa치는 평균값이 .798, 최소값이 .687 최대값이 .933으로 나타나 전체적으로 매우 높은 일치도를 나타내었다. 또한 호흡유형을 들숨, 날숨, 멈춤으로 분류한 세 유형 중에서는, 날숨의 유형에서 그 일치율이 91.7%로 가장 높게 나타났으며 들숨의 유형이 83.3%, 멈춤이 71.4%의 평균값을 보여 전체적으로 매우 높은 일치도를 보였다. 이러한 결과는 한국춤의 전반적인 호흡구조를 이해할 수 있도록 해주는 호흡표기의 활용이 매우 타당성 있는 방법임을 시사해 주는 결과라 하겠다. The present study is a methodological study on a dancing theory and a training method assisting logical understanding of Korean dance. The selected subject was a dancer who directly studied under the originator of the Taegeuk-form ground dance, the object dance of the present study, capable of understanding breathing for the Taegeuk-form ground dance and performing accordingly. The breathing pattern was analyzed by asking the subject to perform dance moves three times pertaining to the second level out of twelve levels of the Taegeuk-form ground dance. The breathing pattern was analyzed from a dancer wearing a mask with thermister and portable gas analyzer (Meta max3B, Germany) to validate the dance notation based on the breathing analysis. According to the present study, coincidence percentages showed the mean value of 84.5%, the minimum value of 75.6%, and the maximum value of 95.1%, while Kappa values show the mean value of .798, the minimum value of .687, and the maximum value of .933, thus proving a very high coincidence level in overall. As for three breathing types classified as inhaling, exhaling, and pausing, exhaling showed the highest coincidence rate of 91.7%, followed by 83.3% for inhaling, and the mean value of 71.4% for pausing, thus proving a very high coincidence level in overall. The outcome clearly implied that utilization of breathing notation helping understand the overall breathing structure for Korean dance could be a very valid way.

Purpose: The purpose of this study was to evaluate the performance of radiologists for mammographic screening, and to analyze interobserver agreement in the interpretation of mammograms. Materials and Methods: 50 women were selected as subjects from the patients who were screened with mammograms at two university hospitals. The images were analyzed by five radiologists working independently and without their having any knowledge of the final diagnosis. The interobserver variation was analyzed by using the kappa statistic. Results: There were moderate agreements for the findings of the parenchymal pattern (k=0.44; 95% CI 0.39-0.49), calcification type (k=0.66; 95% CI 0.60-0.72) and calcification distribution (k=0.43; 95% CI 0.38- 0.48). The mean kappa values ranged from 0.66 to 0.42 for the mass findings. The mean kappa value for the final conclusion was 0.44 (95% CI 0.38-0.51). In general, moderate agreement was evident for all the categories that were evaluated. Conclusion: The general agreement was moderate, but there was wide variability in some findings. To improve the accuracy and reduce variability among physicians in interpretation, proper training of radiologists and standardization of criteria are essential for breast screening. 목적: 유방암 조기검진 방법으로 널리 이용되고 있는 유방촬영술의 방사선학적 소견들과 최종결론에 대하여 판독자들간의 일치율을 평가하여 보고자 하였으며 이를 통하여 유방촬영술의 효과를 높여나가기 위한 기초자료를 마련하고자 하였다. 대상과 방법: 두 개의 대학병원의 유방암센터와 건강진단센터를 내원하여 유방촬영술을 실시한 50명의 여성을 대상으로 하였다. 유방촬영술의 판독은 5명의 판독자로 하여금 맹검법으로 유방촬영술 소견을 판독하도록 하였다. 결과: 유방 실질양상에 대한 판독자간 일치도는 평균 Kappa 값이 0.44로 중간 정도의 일치도를 보였으며, 유방 종괴 경계 양상과 종괴 음영 소견에 대한 일치도는 각각 0.42와 0.51이었다. 유방종괴의 위치에 대한 일치도는 평균 Kappa 값이 0.66으로 비교적 높은 일치도를 보였으며 종괴 크기에 대한 일치도는 0.52였다. 석회화 분포에 대한 일치도는 0.43으로 중간정도를 나타냈다. 정상, 양성과 악성의 최종소견에 관한 일치도는 0.44로 중간 정도였다. 결론: 전반적인 판독자간 일치도는 중간 정도로 양상에 따라 다소 판독자간의 차이를 보였다. 유방촬영술의 정확도를 높이고 판독의 차이를 줄여나가기 위해서는 보다 적절한 훈련과 판정 기준에 관한 표준화가 필요할 것으로 생각된다.

Lee, Kyung Woo,Jung, Byeong Yeal,Hwang, In Yeong,Lee, Su Hwa,Kim, Ji Yeon,Kim, Young Hoan,Lee, Seong Hyo,Moon, Oun Kyoung,Lee, O Soo The Korean Society of Veterinary Science 2009 大韓獸醫學會誌 Vol.49 No.2

Paratuberculosis caused by Mycobacterium avium subspecies paratuberculosis (Mpt) is a chronic infectious enteric disease with deleterious impact on the performance in ruminants. In Korea, ELISA has been introduced to detect antibodies to Mpt in individual cattle. However, comparison study with ELISA has not been studied until now. In total, a panel of 899 serum samples obtained from dairy cattle was analyzed with two commercial ELISAs for Mpt to assess the performance. Two ELISAs employed in this study were both licensed worldwide. Two ELISAs applied onto same serum samples showed the moderate agreement (kappa value = 0.60). There was non-significant McNemar test (p = 0.0614) between two ELISA results indicating that each proportion detected by two kits did not differ. In addition, the percent agreement between two ELISA results was turned out to be 96.8% which interpreted excellent reproducibility. It was shown from this study that two ELISAs revealed moderate kappa agreement performance. The implication raised is that when ELISAs as diagnostics are used to detect Mpt in individual cattle, positive reaction by either ELISA should be interpreted as serologically Mpt positive due to presumed low sensitivity of ELISAs and their test agreement being less than 100%.

1. Objectives and Methods This study was performed to know the relationship between Sasang Constitution and characteristics of ordinary symptoms, inspection diagnosis of face and tongue. There were 666 participants(280 men and 386 women) who answered Sasang Constitutional Checkup list and were taken pictures of faces and tongues. Sasang Constitution was diagnosed by only PSSC(Phonetic System for Sasang Constitution). Distribution of Sasang Constitution and X2 test, kappa value for agreement were calculated using SPSS 10.0. 2. Results From characteristics of ordinary symptoms' point of view, Taeeumin had loud voices, big body shapes and easily sweated themselves. They felt good after sweating and had warm hands and feet. And their upper back, shoulders and chest were, they thought, well developed. They were apt to have meals quickly and overeat themselves. Soyangin and Soeumin had thin body shapes and were difficult to sweat themselves and felt powerless after sweating. They had cold hands and feet. Especially, Soeumin was apt to have meals slowly and a little amounts. They walked so fast. Soyangin was introvert and had developed their abdomen and waist. 'Looking heavy and steady' was higher in Taeeumin, 'delicate and modest' was higher in Soeumin(42.8%) and Soyangin(36.1 %) in first impression. It was thought to be difficult to discriminate Soyangin from Soeumin in first impression and make a notion of right Soyangin's first impression. Soyangin had pinky tongue color and little tongue fur whereas Soeumin had red tongue color and whitish tongue fur. Taeeumin had whitish tongue fur too. 3. Conclusions To diagnose Sasang Constitution much effectively, PSSC results and comprehensive Sasang Constitutional Checkup list extracted from effective Questionnaire items and Face and Tongue Inspection Diagnosis are thought to be needed.

이상아,이경신,김형숙,이해정,최혜미 대한지역사회영양학회 2002 대한지역사회영양학회지 Vol.7 No.4

The purpose of this study was to develop a computer software program for nutritional assessment using a Semi-Quantitative Food Frequency Questionnaire (SQFFQs) and the 24-hour Recall Method. The software for the SQFFQ was divided into input, output, and database. For dietary analyses, recipe and food databases were used. The recipe database included 25 items and the food database was divided into 18 food groups. The food database was composed of 19 general nutrient items, 33 fatty acids, and 18 amino acids. The software developed in this study can be summarized as follows: 1) input items related to the individual s ages information, lifestyle, biological values, and dietary habits; 2) individualized data in percent of the Korean RDA, the energy ratios of carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes; 3) Statistical data on the individual's information, lifestyle, biological values, and dietary intakes including the frequency of intake of cooked foods, the amounts of food, and the number of food groups, and nutrients. In the 24-hour Recall Method, the input and output consisted of the individual s information and cooked dish intakes. The individual s report included the amounts of nutrient intake according to number of meal and days, in comparison to the Korean RDA, the energy ratio for carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes. The statistical report presented the number of food groups and foods, and the nutrient intakes. To evaluate the validity of the SQFFQ, the Spearman Rank Order Correlation and kappa values were used. As a result, correlation coefficients comparing the 24-hour Recall Method appeared to be more than 0.5, except for vitamin $B_1, B_2$, niacin, and vitamin E. The kappa values for energy and carbohydrate intakes were both 0.7, and protein, fat, vitamin C, folate, Ca, and iron intakes ranged from 0.3 to 0.7.

Usefulness Evaluation of Low-dose CT for Emphysema : Compared with High-resolution CT

이원정 대한방사선과학회 2016 방사선기술과학 Vol.39 No.3

The purpose of this study was to evaluate the usefulness of low-dose CT (LDCT) for emphysema compared with high-resolution CT (HRCT). Measurements of radiation dose and noise were repeated 3 times in same exposure condition which was similar with obtaining HRCT and LDCT images. We analysed reading results of 146 subjects. Six images per participants selected for emphysema grading. Emphysema was graded for all 6 zones on the left and right sides of the lungs by the consensus reading of two chest radiologists using a 4-point scale. Between the HRCT and LDCT images, diagnostic differences and agreements for emphysema were analyzed by McNemar’s and unweighted kappa tests, and radiation doses and noise by a Mann–Whitney U-test, using the SPSS 19.0 program. Radiation dose from HRCT was significantly higher than that of LDCT, but the noise was significantly lower in HRCT than in LDCT. Diagnostic agreement for emphysema between HRCT and LDCT images was excellent (k-value=0.88). Emphysema grading scores were not significantly different between HRCT and LDCT images for all six lung zones. Emphysema grading scores from LDCT images were significantly correlated with increased scores on HRCT images (r=0.599, p <0.001). Considering the tradeoff between radiation dose and image noise, LDCT could be used as the gold standard method instead of HRCT for emphysema detection and grading.
