The purpose of this study was to compare the experimental pain threshold when used in luminous lamp radiation and nonluminous lamp radiation with healthy person. Thirty normal subjects were randomly assigned two groups: a luminous lamp radiation group, and a nonluminous lamp radiation group. The infrared lamps were applied on L3 for thirty minutes. Each group was measured for experimental pain threshold and local temperature before, 15 and 30 minute radiation. For statistical differences in change of the experimental pain threshold and local temperature due to differences in lamp ray was compared using the independent t-test. And, General linear model for profile plots test was used. The results were as: 1. Local temperature was significantly increased in the nonluminous lamp group (p<.01). 2. Experimental pain thershold was significantly increased in the luminous lamp group (p<.05),(p<.01). This study indicate that luminous lamp radiation was more effects of increase experimental pain thershold than nonluminous lamp radiation. Further study is needed to compare the effects of after period radiation.

The purpose of this study was to determine the effect of intramuscular stimulation (IMS) therapy in older persons with musculoskeletal pain. The subjects were 181 older persons (54 males, 127 females) with musculoskeletal pain. Intramuscular stimulation unit with needles (size mm) was applied for the treatment. The analgesic effects were measured by visual analog scale (VAS). Results showed that the post-treatment VAS score was significantly decreased after IMS therapy for fifteen minutes compared to pre-treatment score. In addition, the post-treatment VAS score was significantly decreased in patients with chronic pain (pain duration of one year after onset) compared to the post-treatment VAS score in patients with subacute pain (pain duration less than three months after onset). There was no significant difference in analgesic effects according to gender and age groups. It is determined from this study that IMS therapy can be beneficial for patients with chronic musculoskeletal pain in clinical setting. Further study is needed to identify whether the IMS therapy can change the pain threshold in patients with neurologic pain.

The purpose of this study was to compare the body alignment during standing on level and wedge board. Twenty healthy college students (8 females, 12 males) were evaluated in this study. Diagnostic contourline potographic imaging system (Model JTC-1, Jodang Trading Co.) was used to measure body alignment. Sagittal and frontal plane images were used to analyze the body alignment. The result showed that the cervical and lumbar lordotic curve significantly decreased during standing on wedge board when compared with standing on level. On the other hand, thoracic kyphosis significantly increased during standing on wedge board. There was no significant difference in body alignment according to gender, weight, and height. Clinically, patients with low back pain and severe lordosis may be affected by heel wedge. Further study is needed to identify whether the standing on wedge board can change the body alignment in patients with low back pain and spinal deformity.

We have carried out measurements of 1.2-1.6GHz radio interferences around Seoul Radio Astronomy Observatory located in the campus of Seoul National University. We received interference signals using a pyramidal horn antenna and measured its power using a spectrum analyzer with 1MHz resolution after ~60dB amplification. In order to check the spatial characteristics, we made observations at every 30∘ 30∘ in azimuth at elevation of 30∘and60∘ 30∘and60∘ . Also, in order to check the temporal characteristics, we repeated the all-sky observations five times at every six hours. The results may be summarized as follows: (1) There are strong (≥−20dBm) (≥−20dBm) interferences between 1.2 and 1.4GHz. Particularly strong interferences are observed at 1.271 and 1.281GHz, which have maximum powers of -0.34dBm and -0.56dBm, respectively. (2) The characteristics of the interferences do not depend strongly on directions, although the interferences are in general weak at high elevation and in east-west direction. (3) The interferences appear for a very short (≤0.01s) (≤0.01s) period of time, so that the average power is much smaller than the maximum power. Strong interferences with large (≤−49.0dBm) (≤−49.0dBm) average power have been observed at 1.271, 1.281, 1.339, and 1.576GHz. At these frequencies, the interferences appear repeatedly with a period of ≤0.1s ≤0.1s By analyzing the observed power, we find that, for the strongest 1.271GHz interference, the average intensity is −171dBW/m2/Hz −171dBW/m2/Hz and that the maximum intensity is −122dBW/m2/Hz −122dBW/m2/Hz . If this interference is delivered to the detector without any shielding, then its power would be much greater than the rms noise of a typical line spectrum. Therefore, it is important to shield all the parts of receiver carefully from radio interferences. Also, without appropriate shielding, the sensitivity of a receiver could be limited by the interference.

In the history of literature, women have appeared more as subsidiary figures to inspire or help male authors than as creators of literature themselves. Dante’s Beatrice, Petrarch’s Laura, and Dorothy Wordsworth can be cited as classical examples. Maud Gonne, Yeats’s lifelong lover, does not go beyond the boundary. In his poetry, Yeats portrayed her as an embodiment of eternal beauty, femme fatale like Helen of Troy or Deidre of Ireland, heroic figure of unbounded nobility and courage. But Yeats did not always praise and idealize her. He showed his dissatisfaction with her violent political activities and in his poetry she appeared as a heedless, overly proud woman who had wrought her own misfortune. But however diversified and numerous her images may have been, she exists in his poetry as objectified images shaped by Yeats’s transformed imagination. But in 1997, Maud’s letters to Yeats during the entire period of their acquaintance were published. Through them, we can get access to her as ‘a speaking subject’ uttering her own thoughts and emotions. We can acquire firsthand information on their relationship and direct response to the various incidents. By analyzing her letters in detail, I tried to present hitherto unknown aspects of Maud Gonne and shed light on some misunderstandings about her. For example, some critics denounced her indifference to Yeats’ poetry. But in her letters, she continually advised him not to let other activity ― be it political or theatrical―deprive him of his time and energy to engage in his proper work-writing of poetry. And her sincere concerns for the poor, the suffering, and the underpriviledged and her sympathetic understanding of women’s situation in Ireland have been hitherto unappreciated. As this essay’s main concern is Maud Gonne as a speaking subject of the letters, its aim is not an authoritative biographical study on Maud Gonne, but to view her life from a new perspective.

The purpose of this study was to identify vital capacity (VC) in relation to the changing position of 19 patients with spinal cord injury (SCI) and 20 normal controls. Among the 19 SCI patients, there were 9 quadriplegics and 10 paraplegics. The vital capacity was measured in each subject during sitting, standing, lying, and head down position of 30 degrees. The data were analysed by the Kruskal-Wallis test, Mann-Whitney test, and Wilcoxon signed rank test. For the SCI, significant difference of VC accoring to the 4 positions between quadriplegics and paraplegics. In the control group, significant difference of VC according to the 4 positions. In 4 positions the VC of men were significantly larger than that of women between two groups. No statistical significant difference was shown in VC by the postural change between quadriplegics and paraplegics.
