Luby transform (LT) codes were the first practical rateless erasure codes proposed in the literature. The performances of these codes, which are iteratively decoded using belief propagation algorithms, depend on the degree distribution used to generate the coded symbols. The existence of degree-one coded symbols is essential for the starting and continuation of the decoding process. The absence of a degree-one coded symbol at any instant of an iterative decoding operation results in decoding failure. To alleviate this problem, we proposed a method used in the absence of a degree-one code symbol to overcome a stuck decoding operation and its continuation. The simulation results show that the proposed approach provides a better performance than a conventional LT code and memory-based robust soliton distributed LT code, as well as that of a Gaussian elimination assisted LT code, particularly for short data lengths.

How to conceive fraternity in difference? I will hold two premises to answer this question. First: fraternity is an ineradicable element of the Political. Second: the recognition of fraternity in difference is a precondition for the consolidation of fraternal relations in Latin America in the context of coloniality. On the same path, I will show that fraternity must be thought of as difference in order to face the logic of neoliberal life imposed by capitalism in globalization. The articulation of both premises in the political praxis would contribute to the preservation of our life in common; in conditions of dignified existence. The fraters of precariousness and vulnerability are the ones who can re-establish being-with- and being-together.

We constructed an on-line PD monitoring system for the 380kV U/G Cable project at the Riyad 9012 substation in Saudi-arabia. The system will be monitoring the termination of the two 380kV XLPE Cables to prevent unexpected failure of the cable insulation. The system had been tested in the laboratory and on-site for detection of various PD signals and reliability of operation. The system distinguish the existence and nonexistence of the partial discharge and then judge the source of partial discharge using automatic PD pattern recognition software.

Cognitive conflict is well recognized as an important factor in conceptual change and is widely used in developing constructivism-based curricula. However, cognitive conflicts can also contribute to student anxiety during learning, which, when not properly addressed, can have negative impacts on students' motivation and achievement. Therefore, instructors need to be aware of the impacts of introducing cognitive conflicts in their instruction. We need a practical instrument that can help identify the existence and features of cognitive conflicts introduced by the instruction and the resulting anxiety. Based on the literature on studies of cognitive conflicts and student anxiety, we developed a quantitative instrument, the In-class Conflict and Anxiety Recognition Evaluation (iCARE), and used it to monitor the status of students' cognitive conflicts and anxiety in Physics by Inquiry (PBI) classes. In this paper, we introduce this instrument and present the types of information that can be obtained. Research and pedagogical values of this instrument are also discussed.

Ultrasonic inspection of defects has been focused on the existence of defect in structural material and need has much time and expenses in inspecting all the coordinates (x, y) on material surface. Neural networks can have an application to coordinates (x, y) of defects by multi-point inspection method. Ultrasonic inspection modeling is optimized by neural networks Neural networks has trained training example of absolute and relative coordinate of defects, and defect pattern. This method can predict coordinates (x, y) of defects within engineering estimated mean error $\psi$.

'老' refers to the old man with the characteristics of being aged in the original meaning 'to be aged' (adjective), which is a metonymy of 'substituting the whole with a part'. In combination with nouns, '老' uses a lot of metaphorical expressions that are understood through animals closest to the attributes of people with aged characteristics, plants and objects. '老' can be extended to the meaning of 'the survival time, duration, recognition time, and existence time of a person, animal, plant, or object are long', or 'the survival time is over', which can be said to be a metonymy of 'substituting cause with result'. An experienced target respected by people on a positive level and a target with banal thoughts, habits, nature, and personality on the negative level can also be conceptualized and expressed as '老'.

Through this research, it was discovered that Wang Sa-wung studied classics such as "Nai Kyung", and brought about new theries and prescription by combining it with his own experience. He asserted 'Ki Hwa Chu Ki' theory which differentiated 'Shin Kam' and 'Bok Sa' within 'On Byung', and this was a new theory which was not in existence before. The main reason for the recognition received by the future generation is, not only because of the substantial theoretical background but, due to the fact that his ideas were based on making practical use easier within rich near a bed experience.

Image processing steps are consist of image acquisition, preprocessing, region, segmentation and recognition. But image corrupted commonly by noise reduction methods, many filters were proposed like mean filter, median filter, weighted median filter, Cheikh filter, and Kyu-cheol lee filter as spatial noise reduction filtering. We propose a new edge detection algorithm so that we find out edge existence and nonexistence. In non-edge area, we selectively apply weighted median filter based upon using information of difference value between weighted median filter's value and center pixel's value. As a result, we finally prove a better performance of noise reduction by applying adaptive weighted median filter and improvement of processing time through using simple algorithm.

In the past, Chinese arbitral system and Chinese arbitral associations were avoided by international society due to the cases which Chinese court rejected the recognition and enforcement of foreign arbitral awards based on rural protection. Especially Chinese court adjudicated to reject the recognition and enforcement of arbitral awards by interpreting public policy broadly. The abuse of public policy by court threats the existence of commercial arbitration system. Under this awareness, the author figured out Chinese court shows what kind of attitude about public policy of Chinese court in the present through analyzing the cases about rejection of enforcement in Chinese arbitral awards in order to analyze whether Chinese court still maintain the negative attitude like past or there exist changes with public policy which is one of the rejection reasons of recognition and enforcement in foreign arbitral awards as the central figure. Chinese court behaved in an uncooperative attitude about arbitral awards like that it reached a verdict to reject the enforcement of arbitral awards by reason of violation in public policy about several foreign arbitral awards at the beginning stage of establishing arbitration law. However, the situation of abuse in public policy was improved a lot by Chinese prime court which enforces pre-inspection system about judgment of rejection of enforcement in arbitral awards. So, there is no case about rejecting the approval and enforcement of arbitral awards by reason of violation in public policy by Chinese court except Yongning Co. case. Moreover, Chinese court got the trust and support from other countries through reinforcement of applied standard. However, Chinese court had been expressed concern from international society because they highly applied public policy and rejected to enforce arbitral awards in the recent case of Yongning Co.. Therefore, this study examined whether it is appropriate to apply public policy of Chinese court in the case of Yongning Co., and then I concluded that. Although Yongning Co. case is the first case which Chinese prime court agrees with public policy by reason of rejection of approval and enforcement in foreign arbitral awards, in my opinion, it doesn't mean that Chinese court has fundamental change in basic attitude and position about the approval and enforcement of foreign arbitral awards. Chinese court keeps the cautious uses of public policy in legal judgment of foreign arbitral awards and it looks like implementing the obligation in regulation of New York Convention sincerely.

Objectives: This study was performed to examine the factors affecting re-smoking in male workers. Methods: A self-administrated questionnaire survey was conducted during April 2003 to examine the smoking state of 1,154 employees of a company that launched a smoking cessation campaign in1998. Five hundred and eighty seven persons, who had stopped smoking for at least one week, were selected as the final study subjects. This study collected data on smoking cessation success or failure for 6 months, and looked at the factors having an effect on re-smoking within this period. This study employed the Health Belief Model as its theoretical basis. Results: The re-smoking rate of the 587 study subjects who had stopped smoking for at least one week was 44.8% within the 6 month period. In a simple analysis, the re-smoking rates were higher in workers with a low age, on day and night shifts, blue collar, of a low rank, where this was their second attempt at smoking cessation and for those with a shorter job duration (p<0.05). Of the cues to action variables in the Heath Belief Model, re-smoking was significantly related with the perceived susceptibility factor, economic advantages of smoking cessation among the perceived benefits factor, the degree of cessation trial's barrier of the perceived barriers factor, smoking symptom experience, recognition of the degree of harmfulness of environmental tobacco smoke and the existence of chronic disease due to smoking (p<0.05). In the multiple logistic regression analysis for re-smoking, the significant variables were age, perceived susceptibility for disease, economic advantages due to smoking cessation, the perceived barrier for smoking cessation, recognition on the degree of harmfulness of environmental tobacco smoke, the existence of chronic disease due to smoking and the number of attempts at smoking cessation (p<0.05). Conclusion: From the result of this study, for an effective smoking ban policy within the work place, health education that improves the knowledge of the adverse health effects of smoking and the harmfulness of environmental tobacco smoke will be required, as well as counter plans to reduce the barriers for smoking cessation.
