    Forms of Address of the Chepang and English Languages: A Comparative Study
    (Department of English Education, 2007) Paudel, Srijana
    The present study "Forms of Address of the Chepang and English Languages:A Comparative Study" attempts to compare and contrast the forms of addressused in the Chepang and English languages. It shows how native speakers used thewords to address somebody in speech, keeping in mind various factors like age,sex, relation, social setting, culture related to addressors and addressees. Thisresearch compares the forms of address used for consanguineal relations, affinalrelations and social relations including strangers, friends, teachers and students,people holding political, judicial and other positions, professionals like officers,doctors, nurses, drivers and other persons in the Chepang community. To carry out this research, both primary and secondary sources of data have beenutilized. The sample population consisted of forty-five native speakers of theChepang language spoken in Makwanpur district. Data for the English languagehad been taken from secondary sources i.e. English forms of address, differentbooks, journals, research report (References 57-59). A set of questionnaire wasused to collect the data. The way of addressing people in two languages differ in most cases. Usually,kinship terms can have addressee use in the Chepang but first name is moreprominent in the English language. The researcher found out that the Chepanglanguage is richer in the forms of address compared to English. The thesis spreads into 4 Chapters. Chapter one deals with general background inwhich language has been defined, linguistic situation of Nepal, introduction ofChepang, their origin, their language, review of related literature, objectives of thestudy, significance of the study and definition of specific terms. Chapter two isrelated to the methodology, which deals withsources of data, population of thestudy, sampling procedure and tools for data collection, process of data collectionand limitation of the study. Chapter three deals with analysis and interpretation ofthe data. It compare and contrast the two languagesi.e. English and the Chepang.The fourth chapter presents the findings and recommendation and somesuggestions.

    Spatial and Temporal Distribution of Mikania micarantha Kunth in Chitwan Annapurna Landscape (CHAL) Area with Application of Satellite Imageries
    (Department of Botany, 2021) Paudel, Srijana
    Mikania micrantha is a fast-growing neotropical, and the most problematic terrestrial invasive plant species rapidly invading tropical parts of Nepal. Remote Sensing offers synoptic view for detecting and mapping invasive plant species and record changes in actual and potential distribution across wide region over time period. Knowledge based classification approach was used for mapping M. micrantha distribution in Chitwan Annapurna Landscape using multispectral Landsat and WorldView-2 imageries. For Knowledge Based classification, information on elevation, slope, aspect, maximum temperature, minimum temperature, rainfall, unsupervised classified image based on digital number (DN) value NDVI from reflectance and supervised classified image of land use that is suitable for M. micrantha were used as variables for rules. Results have shown increasing trend i.e. 0.1%, 0.19 %, 0.65% and 1.39% of total area of CHAL covered by M. micrantha in 1990, 2000, 2008 and 2018 respectively in Landsat image. WorldView 2 images of different small patch of Chitwan, Nawalparasi, Chitwan-Makwanpur, Chitwan- Tanahu, Makwanpur (Hetauda) were classified and accuracy assessment was done. WorldView-2 images with high spatial resolution than the Landsat images show higher accuracy. Overall accuracy varied from 68.75% to 76% and 79% to 82.5% in Landsat and WorldView-2 imageries respectively. Kappa coefficient varied between 0.37to 0.52 and 0.49 to 0.65 for Landsat and WorldView-2 imageries, respectively. WorldView-2 imageries of high spatial resolution are more effective than Landsat imageries in delineation of Mikania micrantha however Landsat imageries can also be useful in detecting the herbaceous weed.
