Purpose: The purpose of this study was functional leg length inequality effect on COP(Center Of Pressure) and LOS(limits Of Stability) and EMG activation. Methods: The participants were consisted of fourteen. Subjects were distributed 2 groups; control group, leg length inequality ${\leq}3mm$, n=8), experimental group(leg length inequality${\geq}10mm$, n=8). The participants were measured leg length wearing comfortable clothes through tape measure method(TMM). All subjects was measured COP(Center Of Pressure), LOS(limits of stability) using by Balance Trainer BT4(HUR, Finland). Results: The results COP was not exist statistical significant differences(p>0.05). LOS was not exist statistical significant difference(p>0.05). Conclusion: The results was not statistical significant differences COP and LOS depending on Leg Length Inequality. But between experimental group and comparison group was exist mean differences on COP, LOS(COP:Ex.>Com, LOS:Ex. <Com/excepted some data). Somewhat COP and LOS was affected on by Leg Length Inequality. Balance is affected on Leg Length Inequality partly.

The aim of this study was to investigate badminton smash and drop motion depends on player`s level. To perform this study, ten male badminton players were participated: five skilled players (SG, age: 21.6±1.1 yrs, height: 181.4±6.8 cm, body mass: 72.4±5.7 kg, career: 11.2±1.1 yrs) and five less-skilled players (LSG, age: 21.2±1.1 yrs, height: 180.2±5.6 cm, body mass: 73.6±6.7 kg, career: 10.6±0.9 yrs). Three-dimensional motion analysis with 7 infrared cameras was performed with a sampling frequency as 200 Hz. Player`s swing motion was divided into four events: starting motion (E1), backswing (E2), impact (E3), following (E4). For all upper joints, LSG showed greater angle differences between drop and smash motions than that of SG at E3 (p<.05). For all upper joints, greater angular velocities were found in SG than that of LSG. For both groups, significantly smaller angular velocities were found in drop motion than that of smash motion (p<.05). The greater sequential angular velocities (proximal to distal) were found in SG than LSG during smash motion. Based on our findings, performing the same motion between drop and smash would be related to enhance performance at badminton competition. It is expected that these results will be useful in developing a training program for enhancing performance of badminton athletes.

Cholesterol granuloma is a histological term used for the description of a tissue response to a foreign body such as cholesterol crystals. Cholesterol granuloma is histologically characterized as fibrous granulation tissue containing cholesterol crystals within surrounding giant cells. Cases of cholesterol granuloma of the pancreas are very rare. We report a case of a 47-year old male who had a cholesterol granuloma of the pancreas. Abdominal CT showed 24 mm-sized cyst in the pancreas and peri-pancreatic regional mass infiltrating to the stomach. PET-CT revealed increased 18F-FDG uptake at the cyst and peri-pancreatic mass. Thus, Whipple`s operation was done. The disease was confirmed by surgical pathologic examination of the tissue. Pathologic examination of resected specimen showed numerous cholesterol crystals surrounded by multinucleated foreign body giant cells. We report on this case and give a brief review of the literature. (Korean J Gastroenterol 2011;58:353-356)

냉간 단조 공정은 우수한 기계적 물성치와 치수 정밀도를 확보할 수 있어 자동차를 포함한 다양한 산업 및 제품에 활용되고 있다. 하지만 공정 중 발생하는 높은 성형 하중으로 인해 금형 및 장비 수명에 악영향을 미치는 경우가 발생할 수 있어 적절한 하중 분배 및 금형 설계 등 다단 단조 공정 개발에 대한 높은 기술이 요구된다. 본 연구에서는 자동차 유니버설 조인트용 핀치 요크를 제조하기 위한 냉간 다단 단조 공정을 제안하였으며 상용 유한 요소 해석 프로그램을 통한 성형성 평가, 열박음양 제어로 금형 수명을 향상시키고자 하였다. 해석 결과를 바탕으로 다단 단조 금형을 제작하였으며 핀치 요크 시제품의 단류선 관찰, 경도 측정, 미세 조직 분석을 수행하였다. 위 결과를 통해 유니버설 조인트용 핀치 요크 제품을 결함 없이 제조할 수 있음을 확인하였으며, 금형 수명 향상을 위한 열박음양을 제안할 수 있었다. The multi-stage cold forging process should be designed to meet the mechanical property requirement and increase the die life by stress distribution control. In this study, the process was developed to manufacture a pinch yoke of automotive universal joint, and to increase the die life by shrink fit adjustment. To verify the numerical analysis results, the cold forging dies were made and the pinch yoke was fabricated. From the numerical and experimental results, proposed multi-stage cold forging process could manufacture the pinch yoke without crack initiation and might increase the die life by shrink fit control.

무샤노코지 사네아쓰의 이상과 현실

조아라(Jo, A Ra) 동아시아일본학회 2015 일본문화연구 Vol.0 No.56

본고는 아타라시키무라의 창설을 기점으로 이상사회에 대한 무샤노코지의 구상과 현실의 괴리를 고찰하고자 하였다. 이를 위해 무샤노코지가 아타라시키무라의 제창을 위해 쓴 『아타라시키무라에 관한 대화』와 『아타라시키무라의 설명 및 회칙』 을 분석, 비교하였다. 이와 같은 작업을 통해 무샤노코지가 자신의 이상을 현실화하기 위해 제시했던 계획을 실제로 이행하고 있는 것을 확인할 수 있었다. ‘불합리한 생활을 개선하여, 서로 행복하고 인간답게 살고 싶다’는 그의 이상은 아타라시키무라 창설의 원동력이 되었으며, 또한 그는 아타라시키무라를 운영해 나가는 과정에서도 끊임없이 노력하고 궁리했을 것이다. 무샤노 코지의 이러한 자세는 아타라시키무라가 거의 100년에 가까운 역사를 지니게 된 이유 중의 하나라 할 수 있다. This paper focuses on Mushanokoji Saneatsu’s conception and foundation of Atarashikimura. For this, I examined the conditions of ideal society and the terms of the foundation of Atarashikimura through Mushanokoji’s books, The Conversation about Atarashikimura and The Explanation and Rules of Atarashikimura. By comparing the two texts, I was able to discover his volition to narrow the distance between the ideal and reality. Through the analysis of the two texts, I recognized that he actually carried out the plans suggested at the last part of the second conversation, to realize his own ideals. He consistently deliberated and tried to fulfill his plans in the process of the foundation and management of Atarashikimura. This attitude might be one of the reasons why Atarashikimura has an almost 100-year-old history. Also, Mushanokoji’s ideals to live like a human being and live more happily may have been his motives to found Atarashikimura.

연구논문 : 초등학생의 TV 시청 및 인터넷 이용 실태와 식습관의 관련성 연구 -광주,전남 일부지역을 중심으로-

This study was conducted to examine the relationship between dietary habits and time spent watching TV and using internet, in elementary school children. The data were collected by a questionnaire survey of 712 elementary school children, within Gwangju and Jeonnam area. The SPSS 12.0/win program was used to analyze the 523 samples. Amount of TV-watching time was found to be related to the dietary habit score in the subjects. The children who watch TV "less than 1 hour/day" on weekdays had a better dietary habit score than those who watch TV "more than 1 hour" (p<0.0001). The children who watch TV "less than 2 hours/day" on weekends had a better dietary habit than the children who watch TV "more than 2 hours/day" (p<0.0001). The internet usage was also related to the dietary habit score in these children: those who use internet "less than 1 hour/day" on weekdays had a better dietary habit score than the children who use internet "more than 2 hours/day" (p<0.0001). The children who use internet "less than 2 hours/day" on weekends had a better dietary habit score than the children who use internet "more than 2 hours/day" (p<0.0001). These results indicate that the children tend to have a better diet when their TV and internet time is limited and thus healthy dietary behavior is negatively associated with a sedentary pattern of activity in elementary school children.

한글 기반 텍스트형 프로그래밍 언어의 교육적 활용 고찰

조아라 ( A-ra Jo ),김성식 ( Seong-sik Kim ) 한국컴퓨터교육학회 2017 한국컴퓨터교육학회 학술발표대회논문집 Vol.21 No.2

2015 개정 교육과정에 따라 2019년부터 초등학교 5~6학년은 SW교육을 의무적으로 실시하게 되었다. 특히 SW교육을 위한 프로그래밍 언어의 경우 초등학교와 중학교에서는 블록형과 텍스트형 구분 없이 활용할 수 있으나, 고등학교의 경우에는 텍스트 기반 프로그래밍 언어를 활용하도록 제시하고 있다. 하지만 많은 학습 자들이 처음 텍스트형 프로그래밍 언어를 접하게 되면 문법의 어려움과 외국어의 벽에 부딪쳐 어려워한다. 본 연구에서는 학습자들이 처음 텍스트형 프로그래밍을 학습할 때 효율적인 프로그래밍 학습을 위하여 한글 프로그래밍 언어를 사용할 것을 제안한다. 한글 프로그래밍 언어를 교육적으로 활용하였을 때의 장점과 교육적 활용에 있어 고려해야 할 문제점, 한계점 및 보완해야 할 점을 분석해보고자 한다.
