Arecoline is a major alkaloid of areca nuts which are widely chewed by southeast Asian and it manifests various toxic effects in different organs of human and animals. In this work, mature mice were treated by vitamins C plus E, arecoline, or both daily for four weeks. The results showed that arecoline significantly increased the levels of serum alkaline phosphatase (ALP), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) and significantly decreased the levels of reduced glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) in the liver tissues. Additionally, the body weight, testis weight, sperm counts, motility and normal sperms also were significantly decreased. The supplement of vitamins C and E can bring the activities of ALP and GPT to normal levels and partially restore the sperm counts compared to the arecoline-treated group but have no other positive effects. In conclusion, the vitamins C and E partially attenuated the arecoline-induced hepatotoxiciy but basically had on protective effects against the arecoline-induced testicular toxicity.

The ecological expression of art in modern society takes the harmonious developmental relationship between man and nature as an element and combines it with the various manifestations of painting as an expression of ecological artistic development. The necessary relationship for the harmonious development of nature is accurately articulated, and the ecological changes in people are expressed in integrated materials that inspire human reflection. In the pursuit of material pleasures, mankind is neglectful and indifferent to the environment. The development of composite painting in art and ecology is a process that more reveres the harmony between man and nature as well as satisfying the creative value of the work. After systematic evaluation and research, people have engaged in various structural forms of composite art painting development in the long history of art development, focusing on the integration of environmental and ecological culture. In the process of nature education going through development, the comprehensive practical development of nature education is enhanced and efforts are made to feel new ecological art ideas and new ways of valuing environmental protection. In this paper, an observational study of eco-art will be carried out, starting from the theory of hierarchical division and analyzing the contradictory relationship between man and nature. Recognize nature, understand it and feel it through eco-art painting. The analysis of the contradictory relationship between man and nature is combined with the identification of various types of information that give value to the environmental protection public, and the combination of ecological painting and nature art to achieve an upgrade of the environmental protection idea of the value of painting. In the development of artistic ecological comprehensive painting, it is necessary to put forward technical requirements and standards that meet the development of modern industry according to the characteristics and methods of ecological painting. The author of this paper discusses the necessity and social value of artistic ecological painting creation from the artist's point of view, expounds the practical achievements of ecological painting from the perspective of the history and present situation of the development of ecological aesthetics at home and abroad, and gives the concept and creative method of contemporary art comprehensive material painting in combination with his own actual situation.

The highly evolved flowers of orchids have colorful sepals and fused columns that offer an opportunity to discover new genes involved in floral development in monocotyledon species. In this investigation, we cloned and characterized the homologous PISTALLATA-like (PI-like) gene PhPI15 ($\underline{Ph}alaenopsis$ $\underline{PI}$ STILLATA # $\underline{15}$), from the Phalaenopsis hybrid cultivar. The protein sequence encoded by PhPI15 contains a typical PI-motif. Its sequence also formed a subclade with other monocot PI-type genes in phylogenetic analysis. Southern analysis showed that PhPI15 was present in the Phalaenopsis orchid genome as a single copy. Furthermore, it was expressed in all the whorls of the Phalaenopsis flower, while no expression was detected in vegetative organs. The flowers of transgenic tobacco plants ectopically expressing PhPI15 showed male-sterile phenotypes. Thus, as a Class-B MADS-box gene, PhPI15 specifies floral organ identity in orchids.

Hereditary non-polyposis Colorectal Cancer (HNPCC) is an autosomal dominant inheritance syndrome. HNPCC is the most common hereditary variant of colorectal cancer (CRC), which accounts for 2-5% CRCs, mainly due to hMLH1 and hMSH2 mutations that impair DNA repair functions. Our study aimed to identify the patterns of hMSH2 and hMLH1 mutations in Chinese HNPCC patients. Ninety-eight unrelated families from China meeting Amsterdam or Bethesda criteria were included in our study. Germline mutations in MLH1 and MSH2 genes, located in the exons and the splice-site junctions, were screened in the 98 probands by direct sequencing. Eleven mutations were found in ten patients (11%), with six in MLH1 (54.5%) and five in MSH2 (45.5%) genes. One patient had mutations in both MLH1 and MSH2 genes. Three novel mutations in MLH1 gene (c.157_160delGAGG, c.2157dupT and c.-64G>T) were found for the first time, and one suspected hotspot in MSH2 (c.1168C>T) was revealed.

This study suggested that various stakeholder can be participated in regional Environment planning and practical use of policy with rapid assessment of Ecosystem Services(ES). We applied to the rapid assessment of ES method to Ansan city and local registers selected Ecosystem assets that considered to space of ES. Ecosystem assets were measured 5 types Likert scale about 37 indicators of ES and confirm the main ES through the basic statistics. Furthermore Ecosystem assets classified according to similar character of ES. Ecosystem assets of Ansan were selected 47 site and Local climate regulation, Research and education, Primary production was high among the ES indicators. As a result two main group deduced that ecological education group(such as Research and education, Habitat) and safety regulation group(such as Air regulation, Fire regulation) through the factor analysis. In terms of location characteristics of each group, the ecological education-centered ecosystem assets were located near the downtown area, while the safety regulation group was located at the outskirts, such as mountains and coasts. This indicates that the ecological education about the habitat provision can be achieved in Ansan city downtown area and that outskirts should be approached from the aspect of ecological function to establish a plan. The result of Rapid assessment of ES, which can be lead a balanced and developmental consultation when establishing polices for environment planning and management in region.

본 연구는 생태학적 위기와 회복의 과제 앞에서 기독교교육의 역할을 몰트만의 창조론의 관점에서 재고한 글이다. 인류는 여러 차례의 산업혁명을 거치며 산업상의 획기적 발전을 이루어 왔다. 그러나 그로 인해 생태계는 심한 몸살을 앓으며 이상 현상을 드러내는 지경에 이르렀다. 이러한 생태계의 파괴와 고통에 대하여 기독교교육은 자연 세계를 향한 생태학적 감수성을 보다 통전적으로 접근하고 실제적 대안을 제시할 필요가 있다. 몰트만은 오늘날 점증하는 자연에 대한 인간의 착취는 세계가 인간의 소유라는 인간 중심적 생태의식에서 비롯되었다는 점을 상기시킨다. 그러면서 하나님 중심의 생태학적 세계의식으로 전환할 것을 제시한다. '창조공동체', '삼위일체 하나님의 사귐', '안식일을 통한 종말론적 새 창조'는 하나님 중심의 생태학적 세계의식을 집약해주는 주요 개념들이다. 이러한 몰트만의 창조론을 기초로 본 글은 기독교교육이 추구해야 할 생태학적 감수성을 성례전적 창조공동체의 관점에서 살펴보며 기독교교육의 역할과 실천적 대안을 검토하였다. 이를 통해 인간을 포함해 세계는 인간의 소유가 아니라 자연의 일부로서 종말을 향해 함께 지어지며 하나님의 영광을 드러내는 성례전 공동체임을 보여주었다. 더불어 기독교교육은 하나님의 사귐 안에서 사람과 세계의 화해적 사귐을 중재하는 고난받는 주체가 되어야 할 것을 제안하였다. 하나님의 창조를 경축하며 종말론적 창조의 완성을 지향하는 안식일 지킴이 교육은 무너진 생태계의 회복을 위해 기독교교육이 실천할 수 있는 실천적 영역이 될 것이다. 몰트만의 창조론은 그동안 기독교교육이 간과하거나 외면했던 생태환경에 관한 관심과 더불어 생태환경을 복원하기 위한 통전성 있는 기독교교육적 통찰을 제공한다는 점에서 의의가 있다.

This study was aimed at developing and providing textbook writers with information and materials required to introduce forest education ideas and paradigm into primary, middle, and high school students, responding to establishment of the new national curriculum. Research methods included interview with school teachers, literature review on forest education and policy, analysis of writings and drawings of elementary school students. As a primary result, the study produced a framework that can be applied to analyze and understand how people think of and put a value on forest, consisting of 1) Resource-Economic Perspective, 2) Environmental-Ecological Perspective, 3) Cultural-Educational Perspective, and 4) Existential-Ethical Perspective. To test its validity, the developed framework was applied to the processes of reorganizing and interpreting the outcomes of teacher interview and writings and drawings of elementary school students. The results of applications showed that current school education mostly focused on ecological-environmental (about 50%) and cultural-educational (about 30%) perspectives on forest. To improve the quality of current forest education in schools, five main directions including integration, balance, interrelatedness, identity, and systematic approaches were suggested.
