This study aims to illustrate the national images of United Kingdom, France, and Germany based on the descriptions in the Korean middle school Social Studies textbooks in comparative perspective. In order to identify and compare the national images of the three countries, the author uses a framework for analysis consisting cognitive, normative, and relational factors. The main findings are as follows. First, the most frequently shown topics and issues are democratic institutions in the case of United Kingdom, respect for human rights in the case of France, and sustainable environment in the case of Germany. Second, for all the three countries, the most frequent factor among the three is cognitive one, followed by normative and then relational factors. Third, United Kingdom is described as a country of social unrest and conflict as well as a democratic country with long history and tradition. Fourth, France is described as a country of respect/abuse of human rights, potential for high tech industry, and largest agricultural state in Europe. Fifth, Germany is described more as a country of a leading country for global environmental protection than as a country with electronic and information technology.

With a sample of 147 Korean small and medium size companies, this study examined the relationships among degree of information orientation, corporate culture, degree of information management implementation and selected business performances in the process of implementing IMS improvement programs, such as IMS(Information Management System). Information orientation is defined as company-wide understanding and implementation of the underlying philosophy, principles, approached, and tools of information improvement programs. It is assumed that successful implementation of information improvement programs requires a information-oriented mind-set of the employees. The key elements of information orientation include continious improvement structured processes, organixation-wide participation and customer-focused spirit. Culture id defined as the value and beliefs of em organization that shape its behavior. It is also assumed that successful implementation of information improvement programs require strong support from s corporate culture that emphasizes cintinious improvement. Adopting the competing values model of Quinn and McGrath(1985), corporate culture is classified into 'flexible' versus 'controlled culture' and 'outer-directed' versus 'inner-directed culture'. Fitness was defined through the relationship between levels of information oriented and types of corporate culture. The results were as follows. First, it was found that when a company with high information orientation promoted information innovation programs, such as IMS, it reported higher degree of information management implementation and improvement in business performances. Second, the results showed the importance of 'flexible culture' and 'outer-directed culture' in performing information, innovation. Regarding the types of corporate culture, the analysis found that developmental culture, rational culture and group culture were effective. Third, companies with high information oriented and flexible culture or companies with high information orientation and outer-directed culture reported the highest implementation in Information management activities. Fourth, the results showed that the level of information management implementation had a mediating effect on the relationship between information orientation and business performance. It was also found that enhanced non-financial performance led to the improvement of financial performance. This study attempted to exaime the factor that lead information management program to success. In order to reach success, first, it is suggested that companies have positive mind set toward continious information improvement. Secondly, it is recommended that a flexible and outer-directed culture appropriate for continious information improvement is cultivated.

This study analyzes the impact of competitions clinics on the total treatment cost and anti-biotics prescription rate. The result of implementing the basic statistics, correlations, and regression analysis by facilitating the evaluation data by Health Insurance Review & Assessment Service in 2015 for acute otitis media in children is shown as follows. First, there is a significant difference for each si-gun-gu for the competition index between total treatment cost and clinics, but there is almost no significant difference for the anti-biotics prescription rate. Second, competition in clinics has statistically important impact on the total examination cost And, third, competition in clinics has no statistically important impact on the anti-biotics prescription rate. There is a need for additional studies on re-examination rate, treatment cost per visit and so forth in order to clarify other factors of competition for medical institutions impacting on the physician behavior in the future studies.

This study derives the critical success factors through discussion of expert group in operation stage of ERP system that is suggested by the prior study. Relative importance of the derived critical success factors are analyzed using Analytic Hierarchy Process(AHP). In the first layer of the hierarchy, organizational/ human resource factors are appeared to be the most important factors. In the second layer of the hierarchy, CEO support is evaluated as the most important success factor considering the weight of the 1st layer of the hierarchy followed by process optimization, change management, support of the operation department, and maintenance of process innovation organization. This study suggests that, in order to maximize the introducing effect, continuous support and attention of management is not the only requirement. Proper change management to handle the internal environment change caused by the introduction of the ERP system, support of operation department dedicated to ERP system, and separate department for continuous innovation of process are also required.

This study investigates the typology of Internet business models according to revenue sources, and empirically tests how the revenue sources of each Internet business model are different each other. This study consists of the following two steps. First, AHP(Analytic Hierarchy Process) is adopted in developing the influential factors(indexes) for the profitability of each Internet business model and the weight score of each factor. The questionnaire for AHP consists of 47 questions on 9-point scales, and was distributed to 10 experts on Internet business model. Expert Choice program has been used for analysis. Second, the questionnaire to survey the current profitability of each Internet business model was developed on 5-point scale. In order to analyze the actual revenue quality and source of Internet business models, we used MANOVA and ANOVA. This study contributes to develop the desirable revenue or profit model of each Internet business model, and also provides a reference in evaluation of the revenue quality of Internet business models.

The purpose of this study is to evaluate the performance efficiency and productivity change of the regional public hospital in Korea. We use DEA(Data Envelopment Analysis) for CCR, BCC model, and MPI(Malmquist Productivity Index). DEA is a useful nonparametric technique for measurement of efficiency of a DMU(Decision Making Unit) and MPI is a evaluation method to measure DMU's productivity change. We utilize 34 regional public hospital's time-series data over 6 years from 2003 to 2008.The results of this study were as follows. First, technical efficiency(TE) shows that approximately 3.6% of inefficiency exists on the regional public hospitals and it reveals that the cause for technical inefficiency is due to scale inefficiency. Second, MPI's results show that regional public hospital made effort to improve total factor productivity change to raise technical efficiency. In order to raise efficiency, the regional public hospitals should deploy internal innovation and the government should support welfare policies.

In this paper, we propose a new method for detecting digital forgery that identify interpolated region between digital composited images. For detecting the interpolation factor and the tampered regions, we perform two algorithms: The first algorithm is to estimate the interpolation factors using the differential equation for forgery image along the horizontal, vertical, and diagonal directions, respectively; The second algorithm is to scan the interpolation factors along each direction for detection areas as the mask of the optical window size($64{\times}64$) in order to find out the forgery region. A detection map of the forgery is classified with the magnitude of estimated interpolation factors into colors. This detection map can be used to find out interpolated regions from the tampered image. Experimental results demonstrate the proposed algorithms are proven on several examples. We also show the proposed approach is to accurately detect interpolated regions from digital composite images.

This study investigated the attributes of the popular programs by various broadcasting related platforms(on-air, VOD, SNS) and the relationship between the outcomes of these platforms in order to get the implications of broadcasting contents distribution strategy in multi-platform era. First, the study found that drama programs of territorial broadcasting showed the most high performance in on-air platform while comedy entertainment programs got the outstanding achievement in VOD platform. Second, although it had the low ratings in on-air platform, the program could be highly probable to get a great deal of VOD hits if it had attracted the younger audience. Knowledge programs showed the similar outcome between on-air and VOD platforms. Third, the study found that the factor which had a significant influence on VOD performance was the amount of buzz in SNS. These results suggest that broadcasting content distribution strategy in multi-platform era needs the understanding of the segmented target audiences of content and the analysis of trait of each platform.

Receptor modeling is one of statistical methods to achieve reasonable air pollution strategies. In order to maintain and manage ambient air quality, it is necessary to identify sources and to apportion its sources for ambient particulate matters. The main purpose of the study was to survey seasonal trends of inorganic elements in the coarse and fine particles. Second, this study has attempted emission sources qualitatively by a receptor method, the PMF mo-del. After that. both PMF (positive matrix factorization) model and TTFA (target transformation factor analysis) model were applied to compare and to estimate mass contribution of coarse and fine particle sources at the receptor. A total of 138 sets of samples was collected from 1989 to 1996 by a low volume cascade impactor with 9 size fraction stages at Kyung Hee University in Korea. Sixteen chemical species (Si, Ca, Fe, K, Pb, Na, Zn, Mg, Ba, Ni, V, Mn, Cr, Br, Cu. Co) were characterized by XRF. The study result showed that the weighted arithmetic mean of coarse and fine particles were 51.3 and 54.4 $\mu\textrm{g}$/㎥, respectively. Contribution of both particle fractions were esti-mated using TTFA and PMF models. The number of estimated sources was seven according to TTFA model and 8 according to PMF model. Comparison of TTFA and PMF revealed that both methodologies exhibited similar trends in their contribution pattern. However, large differences between contributions were observed in some sour-ces. The results of this study may help to suggest control strategies in local countries where known source profiles do not exist.
