Since the successful launch of FORMOSAT -2 satellite by National Space Organization of Taiwan in May 2004, the Remote Sensing Instrument (RSI) on- board the FORMOSAT -2 has continuously acquired images at one panchromatic and four multi-spectral bands (http://www.nspo.org.tw). In general, the RSI performs well and receives high quality images which proved to be very useful for various applications. However, some RSI panchromatic products exhibit obvious trembling artifact that must be removed. Preliminary study reveals that the trembling artifact is caused by the instability of the spacecraft attitude. Though the magnitude of this artifact is actually less than half of a pixel, it affects the applicability of panchromatic products. A procedure removing this artifact is therefore needed for providing image products of consistent quality. Due to the nature of trembling artifact, it is impossible to describe the trembling amount by employing an analytic model. Relied only on image itself, an algorithm determining trembling amount and removing accordingly the trembling artifact is proposed. The algorithm consists of 3 stages. First, a cross-correlation based scheme is used to measure the relative shift between adjacent scan lines. Follows, the trembling amount is estimated from the measured value. For this purpose, the Fourier transform is utilized to characterize random shifts in frequency domain. An adaptive estimation method is then applied to deduce the approximate trembling amount. In the subsequent stage, image re-sampling operation is applied to restore the trembling-free product. Experimental results show that by applying the proposed algorithm, the unpleasant trembling artifact is no longer evident.

This study is focused on the swinging and trembling effect expressed in Korean costume from ancient days to the present. The swinging is a term standing for gentle movements that are created and implied by the long ties, strings, tassels, pendants and hanging ornamentations. These attatched elements of the costume move as the wearer moves. Trembling is a term expressing small vibrating movement which is created by the tiny decorative motifs attatched to Korean costume. This little decorative elements were attatched to the royal crown, earings, necklaces even the sole of the metalic shoes for a change and to draw viewers attention. The Swinging and Trembling have been used mainly to express the decorative desires. The Swinging on shaman costume is a expression of the aesthetics of evil's eye, while the Swinging shown on the costume of a schalor is expressing the beauty of personality and nature. In General during the Choson Period, the Swinging of the tassels, ribbons, string belts is a expression of the beauty of nature. Consequently the Swinging and the Trembling are the typical examples of the "Meot"(멋), Korean traditional aesthetics.

The inheritance of isoenzymes in young coat tissues of trembling aspen (Populus tremuloides Michx.) was studied by electrophoretically analysing five parental clones and their full-sib progenies obtained by crossing one female clone to four male clones. The distal 2cm section of vigorous young roots of 70 seedlings per family were subjected to horizontal starch gel electrophoresis. The resulting gels were tested for activity of 7 enzyme systems. Evidences for the inheritance of isoenzymes observed indicated that the isoenzyme variants of every isoenzyme zone were under control of codominant alleles at a single locus. Chi-square test of joint segregation data of the two loci, 6-PGD-2 and PGI-2, indicated that the pair of loci was not linked.

Acknowledging that individuals dislike having low relative income renders trade less attractive when seen as a technology that integrates two economies by merging separate social spheres into one. We define a "trembling trade" as a situation in which gains from trade are less than losses in relative income, with the result that global social welfare is reduced. We show that a "trembling trade" can arise even when trade is more gainful in four ways: through trade the absolute income of everyone increases, the income gap in both economies is reduced, as is the income gap between the trading economies. However, trade brings populations, economies, or markets that were not previously connected closer together in social space. As a consequence, separate social spheres merge, and people's social space and their comparators are altered. Assuming that people like high (absolute) income and dislike low relative income, the aggregate increase in unhappiness caused by the trade-induced escalation in relative deprivation can result in a negative overall impact of trade on (utilitarian-measured) social welfare, if the absolute income gains are not large enough to mitigate the relative income losses.

Yoshimasi Todo (吉益東洞), who thought that the books on herbal medicines are the reason for the complicated explanation of the effects of herbs, thought that the articles from Treatise on Cold Damage Diseases (傷寒論) and Synopsis of Prescriptions of the Golden Chamber (金匱要略) are the only books that can identify the effects of herbs. He also thought that the practitioners from the later period have added too much on the original text, which led to his thought that the original text of Treatise on Cold Damage Diseases (傷寒論) and Synopsis of Prescriptions of the Golden Chamber (金匱要略) did not have the explanation that involves the theory of yin-yang(陰陽), the five phases(五行), and three yin and three yang(三陰三陽). From this, he investigated the standards of using the herbs in the Synopsis of Prescriptions of the Golden Chamber (金匱要略) by comparing the articles. In this point of view, Yoshimasi Todo (吉益東洞) said that Poria Scleotium (茯笭) treats palpitations (悸) and 肉瞤筋惕. This meant the symptom of unvoluntary palpitations and the trembling of muscles with wrenching pain. Also, he thought that the symptom of Poria Scleotium (茯笭) in the formula of decoction is shown by the symptoms of dizziness, palpatations, vomiting, trembling of muscles, and cramps. This paper studies on the symptoms that seems close to the meaning of the symptom of Poria Scleotium (茯笭) that Yoshimasi Todo (吉益東洞) meant, which can be summarized to palpatations and trembling of muscles. I wish this paper is of help to those who study Treatise on Cold Damage Diseases (傷寒論), Synopsis of Prescriptions of the Golden Chamber (金匱要略), and the medicine of Yoshimasi Todo (吉益東洞).

A 2-year-old intact female Maltese dog was presented with generalized involuntary tremors and nystagmus without regular direction. The dog was conscious the whole time while it was trembling. Its involuntary tremors were alleviated at rest or during sleep. Magnetic resonance imaging (MRI) revealed asymmetric hydrocephalus and caudal occipital malformation. In cerebrospinal fluid (CSF) analysis, a trace of protein was found and total nucleated cell count (TNCC) was slightly increased. However, infectious pathogens were not found. In complete blood count, there was a mild leukocytosis. After the patient received anticonvulsants (midazolam, phenobarbital, KBr), diuretics (furosemide) with an anti-inflammatory drug (prednisolone, 0.5 mg/kg PO bid), and a proton-pump inhibitor (omeprazole), it showed no improvement. The patient was tentatively diagnosed with corticosteroid responsive tremor syndrome. So the anticonvulsants and diuretics were discontinued and the dose of prednisolone was increased to an immunosuppressive dose (1 mg/kg PO bid). After administering the immunosuppressive dose of prednisolone, the patient did not show nystagmus. Its tremors were much alleviated. However, they did not disappear. Five weeks later, the patient showed gradual improvement but still was trembling when moving around. Nine weeks later, its tremors were similar to before. So diazepam (0.3 mg/kg PO sid) was added to the treatment. After that, its tremors were alleviated more. Prednisolone and diazepam were maintained for about five months, with tapering of the dose of prednisolone (until 0.5 mg/kg PO sid). About 7 months later after the treatment was started, the dog was trembling rarely except when it was excited. Therefore, diazepam was discontinued. This case describes a refractory white dog shaker syndrome successfully managed with long-term administration of a steroid and diazepam.

Residual extractives had a noticeable impact on the brightness of unbleached hardwood kraft pulps (trembling aspen). The brightness-impacting extractives were effectively removed by oxygen delignification. In addition, oxygen delignification was more effective in removing chromophores in hardwood unbleached kraft pulps than in those of softwood (loblolly pine). The residual extractives in unbleached hardwood kraft pulps also affected the pulp color, primarily redness and the L value. These redness-related extractives in unbleached hardwood kraft pulps were also effectively removed by oxygen delignification. There were no significant color differences between untreated and solvent-extracted oxygen-delignified aspen kraft pulps. The residual extractives in unbleached and oxygen-delignified softwood (loblolly pine) kraft pulps did not have a significant impact on either brightness or pulp color.

Timber harvesting impacts on soil microbial populations and respiration rates were examined in naturally regenerating trembling aspen(Populus tremuloides Michx.) stands on two contrasting soils, an Omega loamy sand (sandy mixed, frigid Typic Udipsamment) and an Ontonagon clay loam (very fine, mixed Glossic Eutroboralf). Five timber harvesting disturbances were simulated during winter of 1990 and spring of 1991, including commercial whole-tree harvesting(CWH), winter logging trail+CWH, logging slash removal+CWH(LSR), forest floor removal+LSR(FFR), and spring compaction+FFR. Regardless of soil types, total soil respiration rates of each stand decreased slightly or remained the same after harvesting while microbial population increased progressively during the first two years following harvesting. Microbial populations increased more rapidly and constantly at the sandy site than at the clayey site, which may indicate that the soil physical and chemical conditions changed more drastically for microbial activity following timber harvesting at the sandy site than at the clayey site. However, two kinds of treatment applications-three levels of organic matter removal and two levels of compaction-did not result in significant differences in microbial population or total soil respiration rate at each site during the first two post-harvest years. Total soil respiration of the aspen stands, sum of root respiration and microbial respiration, was a poor index for the microbial activity in this study because aspen kept an active root system for the successive root-sprouts even after harvesting, which resulted in a large portion of root respiration in total respiration.

The purpose of this study is to identify how postural mechanics affects postural control on balance and stability by using frequency analysis technique from the kinematic data acquired during the one leg standing posture. For this purpose, the experimental group consisted of two groups, the normal group (n=6) and the national Gymnastics group (n=6). Displacement data of CoP were analyzed by frequency analysis of rambling (RM) and trembling (TR) by FFT signal processing. As a results, there was a significant difference in evaluating the stabilization index between the two groups with the eyes open and closed one leg stnading (p <.05). The cause of the difference was found to be the output of the maximum amplitude of RM (f1) and TR (f2) (p <.05). In particular, in the low frequency RM of 8-9 Hz, which is a natural frequency of signal wave involved in postural feedback feedback, the main frequency appeared to be performs the exercise mechanism of stable brain posture control. And in the high frequency TM of 120-135 Hz, it is considered that the adaptation of the reflective muscle response is minimized to minimize posture shaking. In conclusion, this study provides evidence for the intrinsic main frequencies according to the postural control ability which affects the CNS in one leg standing.
