  • The excitation temperature and electron number density have been measured for end-on-view ICP discharge. In this work, end-on-view ICP-AES equipped with the newly developed “optical plasma interface (OPI)” was used to eliminate or remove the neg ative effects caused by end-on-plasma source. The axial excitation temperature was measured using analyte (Fe I) emission line data obtained with end-on-view ICP-AES. The axial electron number density was calculated by Saha-Eggert ionization equilibrium theory. In the present study, the effects of forward power, nebulizer gas flow rate and the presence of Na on the excitation temperature and electron number density have been investigated. For sample introduction, two kinds of nebulizers (pneumatic and ultrasonic nebulizer) were utilized.

  • Echocardiography was performed on 29 normal Korea Jin-do dogs(21 adults and 8 prematures) and the images were taken from chordae tendineae level short-axis view, left ventricular outflow tract long-axis view and 4-chamber long-axis view, respectively. The following cardiac parameters, in systole and diastole, were measured on the echoocardographic images: aortic dimension(AO), left atrial dimension(LA), left ventricular internal dimention at end-diastole (LVIDd), left ventricular internal dimention at end-systole(LVIDs), interventricular septal wall thickness at end-diastole(IVSd), interventricular septal wall thickness at end-systole(IVSs), left ventricular wall at end-diastole(LVWd), left ventricular wall at end-systole(LVWs). The cardiac parameters were not significantly different between sex and among imaging planes. The size of cardiac parameters increaed as regression lines according to body weights. These results suggest that the chordae tendineae level short-axis view, left ventricular outflow tract long-axis view and 4-chamber long-axis view can be utilized for the left cardiac examination, and these cardiac parameters can be used to basic dat for diagnosing the cardiac diseases in Korea Jin-do dog.

  • Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.

  • This paper proposes a new software quality model composed of a hierarchy of software quality views and three software quality characteristics models. The software view hierarchy is composed of two levels : end view and means view at the first level, contingency view and intrinsic view as sub-views of means view. Three software quality characteristics models are activity quality characteristics model, contingency quality characteristics model, and intrinsic quality characteristics model, which correspond to end view, contingency view, and intrinsic view respectively. This paper also reclassifies characteristics of ISO/IEC 25000 series SQuaRE's software product quality model according to the proposed software quality model. The results illustrate clearly the shortcomings of SQuaRE's product quality model and how to overcome them. First of all, most of SQuaRE's product characteristics should be redefined and conceptually clarified according to the views on which they are really rested. Much more characteristics should be supplemented too. After that, rigorous empirical researches will become relevant. Causal relationships between activity quality characteristics and characteristics of means view should be empirically researched.

  • This study is intended to analyze the characteristics of the preference according to the locations of view points, which are the current criteria for the evaluation of the view. To this end, a total of fifty one test cases according to view point locations were sampled based on the picture data collected in previous studies, and preference assessment was conducted on these cases to identify preference characteristics, where a five-point Lickert-scale evaluation was performed for each test case, and three test cases for each type were comparatively evaluated. It is deemed that the findings from this study may be used to finally derive qualitative assesment scale for the view seen from apartment units.

  • In this paper, the analysis of practical end-to-end delay in worst case is performed for distributed control system considering the implementation of the system. The control system delay is composed of the delay caused by multi-task scheduling of operating system, the delay caused by network communication, and the delay caused by the asynchronous between them. Through simulation tests based on CAN(Controller Area Network), the proposed end-to-end delay in worst case is validated. Additionally, online clock synchronization algorithm is proposed here for the control system. Through another simulation test, the online algorithm is proved to have better performance than offline one in the view of network bandwidth utilization.

  • Since townscape planning zones were introduced in 2000 by a revised Urban Planning Law, interest and understanding on townscape have been enhanced in Korea. Driven by this trend of the time, interest in townscape planning has been growing in the area of urban planning, and local governments have been expressing their interest in townscape management. This study is intended to provide criteria for setting goals of constructing desirable urban environments in harmony with existing condition in Chung-ju City. To this end, questionnaire surveys and awareness research were administered and following findings were obtained in relation to user-specific preferences on view targets and view points for townscape planning in Chung-ju City. In general, citizens of Chung-ju City were found to prefer townscape frequently in use practically, while residents in other areas preferred such townscape as linked with the city' s overall reputation. Both groups were found to prefer natural landscape (Gaemyeongsan, Namsan, etc.) to artificial one as a view target, and Chung-ju Terminal and the neighborhoods and downtown(Seongseo-dong) were presumably preferred as a view point.

  • Mechanical world view was built by Newton and Decarte approximately 400 years ago. Modern Society has reached at the time for fundamental adjustment and in effect, the paradigm shift is now under way. The new paradigm is the holistic world view that considers the world as the integrated entirety rather than the unity of separated parts. The pluralistic phase which can be considered as general characteristics observed in the art, society and culture in the end of the 20th century is seen as the reflection of this new world view. the complementary relationship between traditionism and modernity and oriental intuitive, holistic approach and western rational analytical approach can be explained when the complementary relationship is recognized with holistic and integrated view. The holistic paradigm and integrated-artistic view are the new aesthetic value which can suggest an alternative for public art of environmental design.

  • The purpose of this study is to examine the historical consciousness and view of the three religions (Buddhism, Taoism, and Confucianism) of Won Cheon Seok who lived a period of historical transition from the end of the Goryeo Dynasty to the early Joseon Dynasty. Actively speaking for the public in his time and having the same attitude as the Neo-Confucian scholars in the end of Goryeo Dynasty, he kept criticizing the abuse of the power by powerful families who made the people fall into a state of distress and misery. He believed the dispatch of troops to conquer the Yodong region as a great opportunity to boost the valiant spirit of his country; however, the reality was quite opposite to his expectation as Lee Seong Gye had withdrawn the army troops at the Wihwado causing a great risk to his country. He took a very hard line stance against what Lee Seong Gye did. Although he was a Confucian scholar, he did not ignore Buddhism and Taoism and understood that after all the three religions were based on the same principle. His deep understanding of Buddhism and Taoism as well as Confucianism helped him to make sense of Confucianism even further. He was able to sublimate the worldly anguish coming from the Confucian thinking system by indulging himself deeply into the world view of Buddhism and Taoism. In the end, his view on the three religions was based on the idea that they taught the same principle. His view of the three religions with transactional features has a huge implication for the contemporary society in which various values and multiple cultures coexist and have more common grounds.
