Objective To investigate differences in the relative sizes of the ankle-stabilizing muscles in individuals with versus without flexible flat feet and to determine predictors of symptom severity. Methods This cross-sectional study included 30 patients with symptomatic flexible flat feet and 24 normal controls. The following were evaluated: foot posture index, resting calcaneal stance position angle, radiographic findings (calcaneal pitch, Meary’s angle, talocalcaneal angle, talonavicular coverage angle [TNCA]), foot function index (FFI), and cross-sectional areas (CSA) of the tibialis anterior (TA), tibialis posterior (TP), and peroneus longus (PL) upon ultrasonographic examination. To address morphometric differences among participants, individual muscle measurements were normalized to proportions of total muscle CSA. Between-group differences were evaluated with independent t-tests. Correlations between muscle ratios, radiographic parameters, and FFI scores were investigated. Logistic regression analysis was performed to determine which parameters predicted severe symptoms. Results The relative size of the TP was significantly greater and those of the TA and PL were significantly smaller in patients with flat feet than in normal controls. Correlations were found among relative muscle CSA ratios, radiographic parameters, and FFI score. Linear regression analysis confirmed that the TNCA and the relative CSA of the PL were independent predictors of symptom severity. Conclusion This study found significant differences in the relative CSAs of the ankle muscles in patients with flexible flat feet versus individuals without flat feet; these differences were significantly correlated with anatomic abnormalities. Symptoms were more severe in patients with relatively greater forefoot abduction and relatively smaller PL.

Aims: Recently, it is well known that sarcopenia is one of the risk factors on post-hepatectomy outcomes in patients with hepatocellular carcinoma. However, there were seldom reports for effect of sarcopenia or sarcopenic obesity (SO) on postoperative outcomes in patients with perihilar cholangiocarcinoma (CCC). The purpose of this study is to evaluate the effect of preoperative sarcopenia or SO on postoperative outcomes in patients with hilar CCC following major heptectomy. Methods: Preoperative sarcopenia and SO was assessed in 328 patients undergoing hepatectomy for hilar CCC at three institution between 2006 and 2016, retrospectively. The sarcopenia was calculated from cross-sectional visceral fat and muscle area on preoperative CT imaging (muscle area/height2 = skeletal muscle index, SMI). SO was defined by visceral fat area/SMI. Results: Preoperative sarcopenia and SO was present in 97 (29.6%) and 98 (29.9%) of the patients. Preoperative sarcopenia itself was not associated with postoperative outcomes. However, the rate of major complication in patients with SO was higher than in those without SO (54.1 vs. 37.0%, P=0.004). Also, postoperative hospital stay was prolonged in patients with SO (18.5 vs. 16.5 days, P=0.038). After multivariable analysis, male sex (OR1.937, 95%CI:1.182-3.174, P=0.009) and SO (OR1.866, 95%CI:1.148-3.034, P=0.012) were independent risk factors for occurrence of major complication. There was no statistically significant in overall survival with sarcopenia or SO. Conclusions: SO was an independent risk factor of major complication after hepatectomy in hilar CCC. As a result, careful postoperative management would be needed after major hepatectomy in patients with hilar CCC in case of SO.

Introduction to Structural Equation Modeling

YoungJu Shin 경북대학교 사회과학기초자료연구소 2016 연구방법논총 Vol.1 No.1

Structural equation modeling (SEM) is an advanced statistical analysis that enables to test various types of mediation modeling. This paper introduces the structural equation modeling (SEM) with the focus of measurement model testing, mediation analysis, and SEM with a full measurement model. It also discusses different types of estimation methods to deal with dataset such as non-normality of data distribution and missingness of the data. This paper provides a useful guideline for analysis of social science research that uses survey data.

This paper aims at comparing hedged expressions in the introduction of master's theses written in Korean by Chinese learners of Korean compared with Korean native speakers based on Hyland (1998). To this end, the master's theses written in Korean were collected from 50 native-speaking Korean writers and 50 Chinese learners of Korean as a foreign language from the field of teaching Korean as a foreign language. Findings show that the theses written by the native-speaking Koreans were more hedged than those by the Chinese learners of Korean.

조선후기 동기창(董其昌) 서화 저작과 이론의 수용에 관한 고찰.

신영주 ( Youngju Shin ) 근역한문학회 2016 한문학논집(漢文學論集) Vol.44 No.-

동기창은 17세기 초반에 조선에 알려지기 시작하였다. 이후로 그의 서화를 본보기로 삼아 학습하는 사람들이 꾸준하게 증가하였다. 동기창이 남긴 서화 저작과 이론도 담론의 중심에서 주목되었다. 특히 禪家의 종파 개념을 활용하여 역대 회화 유파를 남종과 북종으로 양분하였다. 이 이론을 기반으로 북종화와 남종화의 개념을 성립시켰는데, 이것이 이후 조선에 전해져 文人繪畵의 발전과 회화 비평의 발전을 견인하였다. 본고는 조선 후기에 크게 유행하였던 동기창의 서화와 이론이 조선에 어떻게 전해지게 되었는지, 이것이 조선 지식인 사회에서 어떻게 수용 발전되었는지에 대해 문헌 기록을 토대로 검토하였다. Dong Qi chang began to be known in Korea in the early 17th century. It increased steadily since the people that he learned to see the creative painting sand calligraphic works. His paintings and calligraphic works and his theory was also noted in the center of the talk about cultural art. In particular, by utilizing the theory of the Zen sect was divided into two Chinese paintings of the Southern School and northern School. After spreads in the our country, So it led the development of the Literary Artists`` Paintings and led the development of a critique of painting. This paper examined the theory of how the painting Dong Qi chang who rage in the Joseon society, and how it was in vestigated whether the acceptance of the Joseon society

조선의 문헌 속에 그려진 미비(米芾)의 몇 가지 형상에 관한 소고

신영주 ( Shin Youngju ) 한국한문고전학회(구 성신한문학회) 2018 漢文古典硏究 Vol.36 No.1

미불의 서예와 회화의 작품과 이론, 그리고 그의 기이한 행동과 취미가 우리나라에 수용되어 나타난 현상들에 관하여 알아보았다. 미불은 우리나라에 고려시대부터 알려졌다. 그러나 그의 서예를 수용하는 것보다 그의 회화를 즐기고 수용하는 것이 상대적으로 부족하였다. 이는 그의 회화가 수용되지 않았음을 의미하지 않는다. 조선시대 초기의 그림에서 이미 미불의 화법이 수용되었음을 확인할 수 있다. 다만 지식인들이 실용적 기능보다 예술 감성이 극대화되어 있는 미불의 회화를 언급하는 데에 적극적이지 않았기 때문에 기록이 적어진 것이리라 생각한다. 미불 서예도 예술적 측면이 강조되어 있어 조선 사회에서 평가가 갈리었다. 그러나 조선시대 후기로 가면서 점차 그의 서법과 화법에 대한 부정적 인식들이 사라져 갔다. 그 사이 미불에 대한 관심은 오히려 서화에서보다 ‘書畵船’이라는 말로 일컬어지는 서화를 즐기는 독특한 방식과 ‘拜石’이라는 말로 일컬어지는 바위를 몹시 좋아하는 행위에 집중되었다. 본고에서는 미불이 이런 까닭으로 우리나라 문헌에서 기이한 행동을 좋아하고 예술에 몰입하는 예술 취미가 강한 인간의 형상으로 그려지게 되었음을 밝혔다. This study investigated how Mifu's calligraphy, painting and peculiar behavior and hob bies were accepted in Korea. Mifu has been known to Korea since the Goryeo Dynasty. But It was relatively slow to accept his painting rather than to accept his calligraphy. This does not mean that his painting was not accepted. It can be seen from the picture of the early Joseon Dynasty that his painting was already accepted. However, the intellect uals did not actively mention his painting, where artistry is maximized rather than practic ality. For this reason, I think that the records in the literature would be fewer. His calligr aphy was also emphasized on artistry, and the evaluation was divided into various kinds in Chosun society. However, by the late Joseon Dynasty, gradually his negative perceptio ns about calligraphy and painting disappeared. In the meantime, people's interest in him has focused on the unique way of "書畵船" that enjoys paintings rather than calligraphy and painting. It was also focused on the act of loving rock, called ‘拜石’. This study reveals that he is depicted in Korean literature as a man who unique actions and likes art.
