This article discuss for some schemes that previously had proposed for surveys of a fault-telerance technique. Fault-tolerance is the very important issue for reliable communication Hence, to construct network system which has a robust we must set up fault models and consider fault location for faulty models and build up full fault-free network through system reconfiguration. Fault mode1s can be considered under variety fault conditions and we can realize fault to1erance with applying the appropriate fault diagnosis procedure. In this artic1e as set up test set( t= 01,t= 10) and two task phases, we discuss for technique that diagnose any faulty models with irregular interconnection network, which differs from regular one, previously used to deal. And we introduce an algorithm for other interconnection networks to fault diagnosis.

우리나라 무도의 현황과 과제에 관한 연구

The purpose of this study is to investigate the situation of the Korean martial arts based on their contemporary concepts and patterns and propose the tasks to be accomplished by dividing them into martial arts for elite and martial arts for all and analyzing them. The problems for Korean martial are as follows: First, Korean organizations of martial arts have not overcome the distorted history and the absence of concrete ideas. Korean martial arts were introduced from Japan during its control over Korea, and partially from China. However no organizations accept this historical background. The 'Koeanization' with denial of true history has produced the absurd reasoning on the history of martial arts. Most discussions on them have been dominated by narrow and blind obsession on tradition and scientification, resulting in commercialization. Second, unbalanced support and academic unreadiness are pointed out. Putting a priority on Martial arts as sports has resulted in emphasizing their athletic aspects lusing their original meaning. The government's unbalanced supports have prevented martial arts as sports for all from being developed. The government's policy only including such sports as judo, kendo, taekwondo, ssireum, and ushu for the licence of sports leaders is against the rule of fairness by neglecting the supervision at the national level. Third, inappropriate research methods on martial arts should be considered. Most researches on martial arts are composed of personal views and prejudice with few literature, which results in the lack of validity and reliability. The athletic-oriented curricula of undergraduate schools and the tradition -oriented research trends fail to present long-term perspectives and research methods, limiting the current status of martial arts on the past history and invalid research method. Recommendations for further study based on these problems are as follows. First, the concrete ideas and concepts on martial arts should be provided. Academic foundation with understanding the historic changes of oriental culture and the meaning of martial arts must be established. Second, integrated policy for promoting martial arts is indispensable. Establishment of centralized organizations administering their affiliates is strongly suggested. It will facilitate the popularization of martial arts, the integration of similar kinds of martial arts, and the systematization of knowledge. Third, policy for supporting the academization of martial arts are urgently needed. To realize this, support for seminars and academic associations should be done free from political considerations.

In ecology-literature, one of the counterproposals for the ecological crisis is the thought of Lao-tzu. The thought of Lao-tzu, Which was suggested as counterproposal to overcome troublous times, has room for being admitted by the human race today in the ecological crisis. In the view of ecology, the central thought of Taoism is 'becoming free from artificiality and returning to nature, the source of everything‘. The artificial things like human civilization, ethics and institutions eventually make human nature go wrong and result in imbalance of ecosystem. Choi seung ho's poetry is the ecological poetry closely related to the thought of Lao-tzu. Choi seung ho's poetry is brought on by harmful effects from civilization and incisive critical spirit of ecological crisis. In terms of poetic embodiment to criticize reality, it is not just describing or criticizing destruction of ecosystem, but approaching to underlying problem more responsively. In adversarial composition between civilization and nature, it constantly induces human self-awareness and reflection and at the same time leaves its mark of deep insight for nature and eagerness for overcoming actual problem on all over. Like this, Choi seung ho's poetry could reach ecological awareness, because of philosophical grounds. In this paper, the thought of Lao-tzu in Choi seung ho's poetry is divided into three parts. First of all, the thought of nature of 'Tao', second, the recursive thought of serenity-the sourse of everything, third, the thought of true freedom for human and indiscriminate egalitarianism - Useless(無用之用) and Wholism of nature(萬物一齊). The nature of 'Tao' is calm but controls everything. Also, the 'Tao' has feature to revert to its old state. In Choi seung ho's poetry, the feature of 'Tao' is embodied in human body-a part of nature. They are important factors as way of ascetic practices - emptying mind and committing to tranquility. Choi seung ho's poetry have an insight into the true meanings of them through image of 'open space' and 'mirror'. Chuang-tzu suggeted 'Useless'(無用之用) and ‘The theory that this and that are born together’(萬物一齊) to insist Free and Easy Wandering(逍遙) and making all things equal(齊物). In Choi seung ho's poetry, to reveal these thoughts, actuality that human themselves struggle to get out of things from human's desire is showed in contrast with symbols of nature; 'butterfly', 'spider', 'dragonfly',or human's inanity that didn't realize the fact that human live in restriction and discrimination of civilization and institutions is criticized with self-deprecation.

Rosa hybrida L. 'Sandra' was freeze dried and investigated the length fur drying, color change of petal, leaf and stem, and the change of flower diameter, 12 days were needed to dry flower completely by natural drying method, otherwise 2 days needed by freeze drying. There was significant difference between fresh flower and natural dried flower in terms of L, a, b value of petal color, otherwise there was no significant difference between fresh flower and freeze-dried flower. L, a and b value of leaf and stem of freeze-dried flower was different comparing with those of fresh flower, however the degree of difference was not higher than these of natural-dried flower, There was no significant difference between fresh flower and freeze-dried flower in terms of anthocyanin content in petal. The change of flower diameter of natural-dried flower and freeze-dried flower comparing with fresh flower was respectively 52.0% and 9.9%.

Purpose: Thallium behaves similarly to potassium in vivo. Potassium channel opener (K-opener) opens ATP-sensitive K+ -channel located at cell membrane, resulting in potassium efflux from cytosol. We have previously reported that K-opener can alter biokinetics of T1-201 in cultured cells and in vivo. Malignant tumor cells have high Na-K ATPase activity due to increased metabolic activities and dedifferentiation, and differential delineation of malignant tumor can be possible with T1-201 imaging K-opener may affect tumoral uptake of T1-201 in vivo. To investigate the effects of pinacidil (one of the potent K-openers) on the localization of the tumor with T1-201 chloride, we evaluated the changes in biodistribution of T1-201 with pinacidil treatment in tumor-bearing mice. Materials and Methods: Balb/c mice received subcuta-neous implantation of murine breast cancer cells in the thigh and were used for biodistribution study 3 weeks later. 100㎍ of pinacidil dissolved in 200 □ DMSO/PBS solution was injected intravenously via tail vein at 10 min after 185 KBq (5 □Ci) T1-201 injection, Percentage organ uptake and whole body retention ratio of T1-201 were measured at various periods after injection, and values were compared between control and pinacidil-treated mice. Results: Pinacidil treatment resulted in mild decrease in blood levels of T1-201, but renal uptakes were markedly decreased at 30-min, 1- and 2-hour, compared to control group. Hepatic, intestinal and muscular uptake were not different. Absolute percentage uptake and tumor to blood ratios of T1-201 were lower in pinacidil treated mice than in the control group at all time points measured. Whole body retention ratio of T1-201 was lower in pinacidil treated mice (58±4%), than in the control group (67±3%) at 24 hours after with injection of 100 □g pinacidil. Conclusion: K-opener did not enhance, but rather decreased absolute tumoral uptake and tumor-to-blood ratios of T1-201 Decreased whole body retention ratio and renal uptake were observed with pinacidil treatment in tumor-bearing mice.
