    The Effects Of Packaging On Over The Counter Medicine Buyers Behavior: A Case Study In Chain Community Pharmacies Of Addis Ababa
    (Addis Ababa University, 2017-05-02) Mengistu, Biruk; Andualem, Getie (PhD)
    Companies in order to create the right packaging for their products, they must understand the consumer buying process and understanding the role and the impact of packaging as a variable that can influence the purchase decision. So, by understanding what factors influence the buying behavior and what packaging elements are most important help companies making the right decisions about packaging their products. The purpose of this study is to explain the effect of packaging on buyers buying behavior of over the counter medicines. Using judgmental sampling a structured questionnaire written in Amharic was distributed personally to 384 over the counter medicine buyers in chain community pharmacies of Addis Ababa. 360 responses were found to be workable by this study. SPSS V 20.0 was used to analyze the data collected and to test the hypotheses put forward. The finding shows that age of respondents and marital status have statistically significant association with consumer buying behavior of OTC medicine while gender and level of education don’t have statistically significant association with consumer buying behavior.The finding also shows that Package size, packaging material, package design, packaging color, package product information and country of origin were found to be positively and significantly affecting overall buyers buying behavior respectively as they were hypothesized. While graphics of the package did not have a significant effect on buyers buying behavior of OTC medicines. Based on the result of the study, it was recommended that pharmaceutical companies should pay proper attention for good and innovative package.

    Restoration and Retrieval of Historical Amharic Document Images
    (Addis Ababa University, 2014-06) Mengistu, Biruk; Meshesha, Million (PhD)
    Many historical document image collections are now being scanned and made available over the Internet or in digital libraries. However, it is to be noted that effective access to such information sources is limited because of lack of efficient retrieval schemes. The existing methods of searching and retrieving from document images can be conducted with the help of recognition-based (Optical Character Recognition) and recognition-free (Document Image Retrieval) or a combination of these two approaches. These algorithms try to analyze the global or local layout structure for different document images and estimate the similarity among them. A few researches have been conducted to develop a recognition-free document image retrieval system that extracts information from document images relying on image features only. These systems are highly affected by degradation in historical documents which results from paper aging, folding or scanning. In this study, an attempt is made to integrate effective image restoring techniques to enhance the effectiveness of the system in searching within historical document images. This study also improves the online searching process of the system by accepting N-query terms for retrieving relevant documents in addition to image viewer, towards enhancing the interface to the Amharic Document Image Retrieval System. In this study different images restoration techniques are experimented, such as Dilate, Erode and Combination of Mathematical Morphology techniques as well as Haar, Daubechies, and Symlet wavelet techniques. These techniques are experimented in historical documents as well as real life documents. Performance analysis shows that best result is obtained by combining mathematical morphology with Otsu thresholding. Finally, the performance of the system is evaluated before and after the integration of the selected restoring techniques in which an average overall performance of 87.02 % F-measure is registered in documents having low, medium and high levels of degradation with an improvement of retrieval effectiveness by 4.65 % F-measure. The performance registered in this study shows promising result for designing applicable Amharic document image retrieval. The major challenge is unavailability of standardized corpus and the dataset contains limited number of historical document images. Therefore, in the future a standardized corpus should be prepared and used for experimentation in similar studies.
