Changes of protein contents and amino acid composition and SDS-PAGE pattern of protein of mung bean which were germinated in dark at 25℃ for 6 day. The total protein contents gradually decreased during germination and the contents of each fractionative soluble proteins were increased shortly after the soaking of mung bean and gradually decreased during the germination afterwards. SDS-PAGE of albumin fraction showed 18 bands, and during the germination the most of bands were diminished or disappeared. But protein bands at 24,000, 40,000, 45,000, 70,000 dalton position remained until 6th day of germination. SDS-PAGE of globulin fraction showed 6 discrete bands, and during the germination the protein band at 45,000 dalton position disappeard. But the protein bands at 14,000∼25,000 dalton position did not change during the period. SDS-PAGE of globulin fraction showed 10 discrete hands, and during the germination the bands of 45,000∼70,000 dalton become diminished or disappeared. But the bands of 30,000, 60,000 dalton did not change throughout the germination period.

항공사 안전관리시스템에 대한 조종사의 인식과 안전행동에 대한 연구
조성환,김기웅,박성식,Cho, Sung Hwan,Kim, Ki Woong,Park, Sung Sik 한국항공운항학회 2014 한국항공운항학회지 Vol.22 No.2
This paper has tried to research the perception of pilots in a commercial airliners or full service carriers focusing on the airliner's safety management system (SMS). ICAO requires the airliners to set up the basic standards of SMS since the SMS is believed to be the core of the aviation risk management. According to the previous study, it was proved safety climate of an airline affects the safety behavior of cockpit crews. Safety climate is different from safety culture and the safety climate has an advantage to be measured more quantitatively than the culture. That is, the safety climate could be represented as SMS. As the results of the empirical study based on Chen & Chen(2014)'s SMS practice sacle, it had been assumed at the beginning the major factors such as Clarification of SMS, Safety Training for Crews and Sharing of SMS Information have positive effects on the motivation for safety behaviors. The motivation is directly correlated to crews' safety behaviors. However, the result showed the clarification of SMS has not a significant effect on their safety behaviors. The main reason is cockpit crews, through the survey, perceived airline seemed to have no definite standards of SMS and the senior management to have less interest in aviation safety.

도시 매체와 인력거 -인력거를 따라 근대 도시의 풍경선 둘러보기-
조성환 영남중국어문학회 2012 중국어문학 Vol.0 No.59
從日本進口的人力車,經由香港、上海(1874),1886年才最終出現在北京的街道上。人力車一出現,便成爲爭議的對象。轎子或馬車最爲進步的東西雖然得到了承認,但用人來馱人,拉人却成爲人類進步中的退步,作爲자取的象征留下深深的烙印,一直延續到中國 5·4運動時期。人力車曾經作爲東亞,包括中國、韓國、日本的都市市民的代替兩脚行走的交通手段。日帝强占時期,韓國在日本的留學生,爲了쟁學費,曾拉過人力車,淸朝滅亡後,滿洲旗人中在生存的壓力下,也被迫고拉人力車來維持生存,甚至因爲生存,有的女性假扮男裝,從事男人都深感吃力的重勞動。東亞都市市民有相當數量的人是人力車夫的後代。本論文中,不僅僅闡述所謂的"人力車夫"這類登場人物,還探索文學作品的背景所構成的地理空間之間的關系, 卽從``文學地理學``(literary geography)的角度,考察都市媒介的人力車以及追隨人力車,審視北京、上海、京城的風景線。還考察隨著交通手段的近代化,人力車退出的過程以及都市貧窮文學和人力車的關系。21世紀人力車還有마?不會已經是陳列在博物館裏的東西了파?但實際上現代化的都市市中心仍然有人力車在奔走著,正如大家看到的,在吃力地奔走著。記憶的力量直到現在爲止一直無窮無盡地持續著奔湧而來。如果去中國的大都市和名勝之地看看的話,街道上擺放著用靑銅或鐵制造的過去``人力車夫``的雕像,以此來吸引遊客,成爲合影照相的對象。過去爲了維持生存而拉的人力車已經成爲複古的文化商品。北京的``胡同遊``,越南的三輪車旅遊,日本東京淺草人力車已經成爲市區旅行的特色。首爾的某飯店,用人力車拉客人來飯店,成爲新出現的拉客的媒介。現代版的``祥子``,``金僉知``,``阿金``等後代們正沈迷於雕像的遺物之中。對於這些,更需要細致的跨學科分析和硏究,作者的視角(通過審視、聆聽、閱讀和書寫),人力車客人的視角(乘坐、討價、蠻橫、本國人和外國人的民族沖突),人力車夫的視角(拉、討錢、擦),文化地理的視角(短途、長途),本國語(方言)和外國語表達力,人力車夫的衣食住,家庭的生存問題等多角度的分析和整理,成爲筆者的任務。

연구배경: 최근 비알코올성 지방간의 예방과 치료에 있어 신체활동량의 중요성이 부각되고 있다. 이 연구의 목적은 신체활동량과 초음파로 진단된 비알코올성 지방간과의 관계를 조사하는 것이다. 방법: 2007년 4월에서 2007년 6월까지 일개 종합건강검진 센터를 방문한 성인 595명을 연속 추출하여 설문지 작성 및 신체계측, 혈액검사를 시행하였다. 설문지는 한국어판 단문형 국제신체활동설문(IPAQ)을 사용하였으며, 알코올 섭취량이 주당 140g 이상인 사람과 기타 간에 영향을 줄 수 있는 요인을 지니고 있는 사람을 제외한 198명을 대상으로 임상적 특성, 생화학적 특성 및 신체활동량과 비알코올성 지방간과의 관계를 조사하였다. 결과: 주당 1500 MET-minutes 이상의 신체활동량을 보인 군이 이하의 군에 비하여 비알코올성 지방간의 위험이 유의하게 낮았으며(9.6% vs 19.2%, P<0.05), 나이, 체질량지수, HDL 콜레스테롤, 중성지방, 공복혈당, 인슐린 저항성을 보정한 후에도 지방간의 위험이 유의하게 낮았다(Odds ratio 0.23[95% CI 0.07∼0.77, P<0.05]). 신체활동 단계에 따른 지방간의 위험은 통계적으로 유의하지 않았지만 남성의 경우 단계가 증가할수록 비알코올성 지방간이 감소하는 경향을 보였다(P=0.059). 결론: 신체활동량이 많은 사람은 신체활동량이 적은 사람에 비해서 비알코올성 지방간의 위험이 적었다. 이는 지속적이고 적극적인 운동을 통하여, 비알코올성 지방간의 유병율을 줄일 수 있는 가능성이 있음을 의미한다. Background: There is an increasing interest in physical activity as a preventive and/or therapeutic option of non alcoholic fatty liver disease (NAFLD). The aim of this study was to examine the association between physical activity and ultrasound-diagnosed NAFLD. Methods: From April to June 2007, 198 clients who had consumed alcohol less than 140 gram per week among 598 clients who visited a general hospital for medical check-up were enrolled in this study. Clinical, biochemical variables and physical activity were compared. Physical activity was measured by self-reported questionnaire using IPAQ-short form in Korean version. Multiple logistic regression analysis was used to identify independent association. Results: The prevalence of NAFLD was significantly lower in the physical active group (more than 1500 MET- minutes per week) compared to the inactive group (9.6% vs 19.2%, P<0.05). This association was not attenuated when adjusted for age, BMI, HDL cholesterol, triglycerides, fasting glucose, and HOMA2-IR (Odds Ratio 0.23 [95% CI 0.07∼0.77, P<0.05]). Conclusion: Compared to the physically inactive group, the risk of NAFLD was lower in the physically active group. Our data suggests that regular and moderate physical exercise can prevent the development of fatty liver disease.
