  • Obejectives : The electroacupuncture(EA) on regional fat is often used by oriental medicine doctors in Korea. However, there have been few studies about safety and biocompatibility of its application. Therefore we investigated the safety and change of mechanical character of electroacupuncture after its application on localized fat deposit. Methods : Online surveys were completed from Aug 21 2008 to Aug 28 2008, by email, the online survey data were obtained from nearly 10,002 Korean medical doctors who listed their email address on the website of association of korean oriental medicine. This study includes an experiment on the physical strength and biological property of long needles. We represent each method which were collected in advance survey, then sealed the needles off and did laboratory experiment, which includes surface observation, analysis, vickers hardness test, and also biocompatibility and toxicity test. Results : There was no considerable difference about the physical property after applying electric current, the cell survival rate did not change in comparison with controlled group either. Conclusions : Although it seems there are no considerable acupuncture-related problem, we still need additional studies about clinical effectiveness difference related operation condition. Besides, it will need research on the actual condition, standardization, and criteria about the comsumed needle in Korea.

  • Texa of Lycoris in Korea were classified as five species with two varieties and revised taxonomically. Among the examined taxa, five Korean endemic plants were clarified: Lycoris flavescens M. Kim et S. Lee, L. uydoensis M. Kim, L. chejuensis Tae et S. Ko, L. chinensis var. sinuolata Tae et S. Ko, and L. sanguinea var. koreana (Nakai) T. Koyama. It was found that L. flavescens, L. uydoensis, and L. chejuensis were the natural hybrids between taxa of M+T karyotype and A karyotype. A specimen collected on Aug. 20, 1987 by M. Kim was designated as a holotype of Lycoris flavescens M. Kim et S. Lee. Lycoris flavescens var. uydoensis was ranked up to L. uydoensis. A key to all species including descriptions of each taxon was provided.

  • A general construction algorithm of the Grassmann space parameters in linear systems - so-called, the Plucker matrix, 'L' in m-input, p-output, n-th order static output feedback systems and the Plucker matrix, $'L^{aug}'$ in augmented (m+d)-input, (p+d)-output, (n+d)-th order static output feedback systems - is presented for numerical checking of necessary conditions of complete static and complete minimum d-th order dynamic output feedback pole-assignments, respectively, and also for discernment of deterministic computation condition of their pole-assignable real solutions. Through the construction of L, it is shown that certain generically pole-assignable strictly proper mp > n system is actually none pole-assignable over any (real and complex) output feedbacks, by intrinsic rank deficiency of some submatrix of L. And it is also concretely illustrated that this none pole-assignable mp > n system by static output feedback can be arbitrary pole-assignable system via minimum d-th order dynamic output feedback, which is constructed by deterministic computation under full­rank of some submatrix of $L^{aug}$.

  • Authors surveyed the inhabitants in Ulnung Island to assess the patterns of medical utilization. One hundred eighty six population(65 male and 121 female) were surveyed with formed questionnaire from Aug. 16 to Aug. 19 in 1994. Results are as follows. 1. The prevalence rate of acute diseases was 19.3%. 2. The prevalence rate of chronic diseases was 35.0%. In classification of chronic disease, the disease of musculoscletal system was the highest(33.9%) and that of digestive system in next order. 3. The first-visit medical facility when disease developed was community health center mainly. The admission care was taken in 37.6%. The 80.0% among location of medical facility for admission care was out of island. The surgical operative care were taken in 19.9%. The 86.5% among location of medical facility for surgical operative care was out of island. 4. Among the contents of dissatisfaction for medical service within island, 'Insufficient equipment' was the highest(35.8%), and 'Insufficient traffic networks' in next order. The results of this study suggest that public health facilities and medical personnel be strengthened and emergency transfer system be secured in Ulnung Island.

  • The purpose of this study was to identify relationship between anxiety and. coping in open heart surgery patients to provide basic information for nursing intervention in stress-coping paradigm. Data were collected from Aug. 1st to Aug. 31st, 1988 through individual interview for about 30 minutes. Tools for this study were 'Spielberger's state anxiety scale and Billings & Moos' coping scale. The subjects were 29 male and 27 female patients who had open heart surgery at S.N.U.H. The data were analyzed by Mean score, Percentage, Pearson product moment correlation coefficient T-test, ANOVA test, and Cronbach's reliability test. The results were as follows. (1) The reliability of coping scale was 0.751 by Cronbach's reliability test. (2) Average coping score of those patients was 2,53 (maximum score:4) and they used equally problem focused coping and emotion focused coping. (3) There was significant difference according to religion in stress·coping(F=2,495, P<0.05) (4) The high anxieties were, the more coping were, and there was significant negative correlation in stress-coping (r=-0.2807, P<0.05)

  • CQUEAN (Camera for QUasars in EArly uNiverse) is an optical CCD camera system that consists of a science CCD camera, a guide CCD camera, and seven filters. In addition, a focal reducer is installed in front of the science camera to secure a larger field of view for the system. Engineering run of the system was carried out from Aug. 10, 2010 to Aug. 17, 2010, with 2.1m Otto Struve telescope at McDonald Observatory, USA, from which we investigated the characteristics and performance of the system. Bias and dark images were taken under various temperature conditions to examine the system behavior, and both twilight and dome flat images were obtained to investigate the appropriate preprocessing procedures of the data. Crude initial estimate indicated one hour integration would reach limiting magnitude of 24.2 in i-band with S/N ratio of 5, with CQUEAN at 2.1m telescope. The detailed results of the engineering run will be presented.

  • CQUEAN (Camera for Quasars in EArly uNiverse) is an optical CCD camera system which has its own auto-guiding system. Guiding system consists of a 1k*1k CCD camera, FLI PL1001E, a flat mirror to feed the image of an off-axis field to the camera and baffle. The whole system lies on a moving arm which rotates 90 degree effectively to enlarge the field of view. A motor, IMS MDRIVE 34, and a differential decelerator, APEX AD140-050, are used for the moving mechanism. Auto-guiding is controlled by Agdr program. We had a first light from Aug. 10 to Aug 17, 2010 at McDonald Observatory, USA. In this presentation, we describe about the auto-guiding system for CQUEAN and its performance on the 2.1m telescope.

  • This study was done to examine the relationship between stress and coping methods of 86 emergency medical technicians with the 1st or 2nd grade qualifications who serve at 36 fire stations in Gwangju and Jeonnam region from Aug. 1 to Aug. 31, 2001. Data collection was done by questionnaire. The research instruments used the stress measure tool developed by Cho Hee et al.(1999) and revised and complemented by the researcher to measure firemen's stress, and health instrument revised by Suh Mi Hye et al(1993). Data were analyzed by t-test, ANOVA, and Pearson's correlation using SPSS. The results of this study were as follows : 1. The mean score of perceived stress was 3.4. The mean score of coping methods was 2.11. 2. The levels of stress according to the general characteristics of subjects were significantly different at marital status(t=7.054, p=.009) and in relation with organization(t=3.989, p=.049). 3. The relationship between levels of stress and health status was significantly correlated(r=.325, p=.000), and so the hypothesis of this research, "the less levels of stress, the better health status is." was supported. 4. The relationship between stress and health status was significantly different at crisis status(r=.393, p=.000), relation with organization(r=.348, p=.001), the characteristics of subjects(r=.387, p=.000), special knowledge and technology(r=.337, p=.001), and the roll complication as a professional(r=.343, p=.001).

  • Generally, Hwabyung is more commen in older women, in low educational group. Many psychiatrists explain it as the illness originated from a series of psychological stresses. And they think that Hwabyung patients have somatization disorder, anxiety disorder, and, major depression. But, many of oriental medical doctors explain it as symptoms having the character of fire. In order to investigate the clinical aspects of Hwabyung, this study was carried out in department of oriental neuropsychiatry at Kyung Hee Medical Center. The subject was 34 year old female who was an inpatient in K.M.C from Aug. 14 Aug 26, 1996.The results of the study showed that familial problem and long-termed(about 10 years) stressed situation drove her to Hwabyung. This seems to be related to Korean traditional culture. That is, Korean women were exposured to familial problem(related to mother-in-law, and, her husband), and, poverty, etc. But they had to be patient of this situation. Nowadays, though this situation is rather improved, Hwabyung remains a problem with us, because many people still suffer from Hwabyung.
