Herein, a novel ginsenosidase, named ginsenosidase type IV, hydrolyzing 6-O-multi-glycosides of protopanaxatrioltype ginsenosides (PPT), such as Re, R1, Rf, and Rg2, was isolated from the Aspergillus sp. 39g strain, purified, and characterized. Ginsenosidase type IV was able to hydrolyze the 6-O-α-L-(1→2)-rhamnoside of Re and the 6-O-β-D- (1→2)-xyloside of R1 into ginsenoside Rg1. Subsequently, it could hydrolyze the 6-O-β-D-glucoside of Rg1 into F1. Similarly, it was able to hydrolyze the 6-O-α-L-(1→2)- rhamnoside of Rg2 and the 6-O-β-D-(1→2)-glucoside of Rf into Rh1, and then further hydrolyze Rh1 into its aglycone. However, ginsenosidase type IV could not hydrolyze the 3-O- or 20-O-glycosides of protopanaxadioltype ginsenosides (PPD), such as Rb1, Rb2, Rb3, Rc, and Rd. These exhibited properties are significantly different from those of glycosidases described in Enzyme Nomenclature by the NC-IUBMB. The optimal temperature and pH for ginsenosidase type IV were 40℃ and 6.0, respectively. The activity of ginsenosidase type IV was slightly improved by the Mg2+ ion, and inhibited by Cu2+ and Fe2+ ions. The molecular mass of the enzyme, based on SDS-PAGE, was noted as being approximately 56 kDa.

Yu, Dong-ming,Xia, Tian-Tian,강태호 한국전통조경학회 2016 한국전통조경학회지 Vol.14 No.-

In the process of urbanization and new village construction, a number of villages witnessed qualitative changes. The hollowed village is a representative. Base on the analysis of the negative effects of hollow village, this paper takes the villages in E’zhuang area in Zibo City, Shandong Province as an example and explores the artistic means of revitalization for the villages. With the method of field investigation and in accordance with the regional features and artistic context, some revitalization approaches were proposed. For instance, the protection and exploration of the artistic resources such as traditional residences, streets and ancient trees, the artistic activities including sketching, artistic works appreciation and visiting the archetype in the villages, the foundation of artistic studios of paintings, calligraphy, rocks, root carving, pottery, porcelain, folk museum etc., the construction of mural villages, the advertising of photography, opera, film and television shooting spots, the exhibition of the artistic life and production, and the introduction of landscape to the courtyards, and so on. It aims to build a new village with regional features.

ORIGINAL ARTICLE : From Blemish to Decoration: the Landscape of Municipal Facilities in Urban Green Space

( Dong Ming Yu ),( Yong Ji Piao ),( Tae Dong Cho ),( Gab Soon Park ) 한국환경과학회 2014 한국환경과학회지 Vol.23 No.1

As the combination of technique and art, environmental facilities have the function to improve the image of urban green space. Among these facilities, some can be designed and arranged reasonably. But to the facilities of sewage, electricity and sanitation and so on, are usually ignored and become the blemish in the green space. Based on the analysis of the status, taking the design of well cover of sewage as an example, the landscape approaches are discussed from form, material, color and artistic technique and so on.

태산 풍경구 교량의 환경 요소 및 조경 기법 분석

( Dong Ming Yu ),( Shuang Sun ),( Tai Ho Kang ) 한국전통조경학회(구 한국정원학회) 2015 Journal of Korean Institute of Traditional Landsca Vol.13 No.-

도로를 개설하기 어려운 하천이나 협곡을 건너가기 위해 건설하는 교량은 교통의 기능뿐만 아니라 경관과 문화적인요소를 가지고 있어 ‘경관교량’이라 칭한다. 태산풍경구내에는 자연과 인문자원이 풍부하고 경관교량을 구성하고 있는 주변의 환경요소가 다양하여 유네스코에 의해 세계문화유산과 세계지질공원으로 지정되었다. 본 논문은 태산풍경구의 문헌연구와 현장조사를 통해 자연환경 요소와 인문환경요소 두 가지 측면에서 태산풍경구에 설치된 교량에 대한 경관영향 및 조경기법을 분석하고 환경요소의 특성 및 형식에 따라 자연환경과 인문환경으로 분류하여 연구하였다. 자연환경은 지형, 물, 식생 등이 있으며, 인문환경은 석각(石刻), 패방(牌坊) 등을 포함하고 있다. 연구결과 경관교량은 태산풍경구 환경과 경관요소로서 매우 중요한 영향을 미치고 있는 것으로 나타났으며 주요 조경기법으로 점경(點景), 차경(借景), 대경(對景), 광경(광景), 장경(障景) 등이 있어 산악형 풍경지구내 경관교량에 대한 디자인 및 계획, 보호, 개조에 요구되는 이론적 근거를 제시하였다. Bridges are built over rivers, gorges or other places where roads are impossible. Those which have traffic, decorative and cultural functions are usually named as garden-bridges. Mount Tai Scenic Area locates in the middle part of Shandong Province, China. It is renowned for its rich natural and cultural resources and ranks No.1 among the five most important mountains in China. It was honored as Mixed World Heritage and Global Geopark. There are decades of different bridges in the Scenic Area. Most of them have important values. Based on field survey and literature research, this paper takes the two main route (mid-climbing rout and west climbing route) as the research objects. The landscape characteristics of garden-bridge together with the surrounding environmental elements are studied. The environmental elements are classified into two categories according to their attributes and existing forms: one is natural and the other is cultural. Furthermore, The natural category includes topography, water, plant and climate etc. The cultural elements mainly consist of memorial archway(牌坊), pavilion and stone inscription etc. Their functions and effects on the garden-bridges are analyzed systematically. As a result, integrating the garden-bridge with the surrounding environmental elements as an organic group, garden-bridge landscape making techniques such as scenery inscription, view borrowing, opposite scenery, frame scenery and obstructive scenery are discussed. It puts forward to give some theoretical and practical references to the garden-bridge’s planning and design, protection and improvement in mountainous scenic areas.

우동명 ( Dong-ming Yu ),장푸천 ( Fu-chen Zhang ),강태호 ( Tai-ho Kang ) 대한관광경영학회 2016 觀光硏究 Vol.31 No.4

중국 산동성 중부 산간에 위치하고 있는 아장고촌은 전통 농촌마을로서 오랫동안 축적되어 온 자연과 인문환경의 특색을 잘 간직하고 있어 관광객과 예술가들이 자주 찾아가는 곳이다. 본 연구는 농촌을 대상으로 하는 사생화 활동이 관광 발전에 미치는 영향을 분석하고자 수행하였다. 연구 방법은 경제, 사회, 생태, 문화 등 마을의 관광 발전에 영향을 미치는 18 가지 지표를 선정하고 현장조사와 설문조사를 통해 사생화 활동이 마을 관광 발전에 미치는 영향에 대한 마을주민들의 인지와 태도를 분석하였다. 연구 결과 마을주민의 성별, 연령, 문화 수준, 가계소득 등 인구학적 특징의 차이에 따라 사생화 활동과 관광 발전에 대한 인지와 태도가 다르게 나타났지만 전체적으로는 긍정적으로 나타나 마을주민이 예술인 및 관광객과 조화롭게 지낼 수 있을 것으로 판단된다. 아울러 부정적인 측면으로 나타난 마을주민의 ``냉담``, ``걱정, ``반대`` 등 소극적인 태도를 효과적으로 감소시키기 위한 정책 방향 제시에 유용한 자료가 된다. Ancient villages are attractive places to the artists and tourists for their unique natural and cultural heritage. This research investigates the ancient villages locate in E’zhuang Town, a mountainous area in middle-Shandong Province, which are the national-renowned destination for artistic sketch and rural tourism. The research adopts methods of field survey, questionnaire and interview. 18 economic, social, ecological and cultural indexes are selected for the investigation of local residents’ perceptions and attitudes towards the development of sketch base and rural tourism industry. Based on the research, the paper explores the differences in perceptions and attitudes among local residents with different demographic features such as gender, age, education level and family income etc. The results show that the common attitude is positive which means local residents are willing to contact and be in harmony with the painters and tourists. The research will do some help to promote the formulation of policies for the related decision-makers to avoid or shorten the apathy, annoyance or even antagonism Stage.

No Association Between MTHFR A1298C Gene Polymorphism and Head and Neck Cancer Risk: A Meta-analysis Based on 9,952 Subjects

Niu, Yu-Ming,Shen, Ming,Li, Hui,Ni, Xiao-Bing,Zhou, Juan,Zeng, Xian-Tao,Leng, Wei-Dong,Wu, Ming-Yue Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.8

Objective: Findings for associations between the methylenetetrahydrofolate reductase (MTHFR) A1298C gene polymorphism and head and neck cancer risk have been conflicting. We therefore performed a meta-analysis to derive a more precise relationship. Methods: Ten published case-control studies were collected and odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association between MTHFR A1298C polymorphism and head and neck cancer risk. Sensitivity analysis and publication bias assessment also were performed to guarantee the statistical power. Results: Overall, no significant association between MTHFR A1298C polymorphism and head and neck cancer risk was found in this meta-analysis (C vs. A: OR=1.04, 95%CI=0.87-1.25, P=0.668, Pheterogeneity<0.001; CC vs. AA: OR=1.07, 95%CI=0.70-1.65, P=0.748, $P_{heterogeneity}<0.001$; AC vs. AA: OR=1.06, 95%CI=0.88-1.27, P=0.565, $P_{heterogeneity}<0.001$; CC+AC vs. AA: OR=1.06, 95%CI=0.86-1.30, P=0.571, $P_{heterogeneity}<0.001$; CC vs. AA+AC: OR=1.02, 95%CI=0.69-1.52, P=0.910, $P_{heterogeneity}<0.001$). Similar results were also been found in succeeding analysis of HWE and stratified analysis of ethnicity. Conclusion: In conclusion, our meta-analysis demonstrates that MTHFR A1298C polymorphism may not be a risk factor for developing head and neck cancer.
