Cosmic rays are ions that move at relativistic speeds. They generate secondary cosmic rays by successive collisions with atmospheric particles, and then, the secondary particles reach the ground. The secondary particles are mainly neutrons and muons, and the neutrons are observed by the ground neutron monitor. This study compared the diurnal variation in cosmic ray intensity obtained via harmonic analysis and that obtained through the pile-up method, which was examined in a previous study. In addition, we analyzed the maximum phase of the diurnal variation using four neutron monitors with a cutoff rigidity below approximately 6 GV, located at similar longitudes to the Oulu and Rome neutron monitors. Expanding the data of solar cycles 20-24, we examined the time of the maximum cosmic ray intensity, that is, the maximum phase regarding the solar cyclic modulation. During solar cycles 20-24, the maximum phase derived by harmonic analysis showed no significant difference with that derived by the pile-up method. Thus, the pile-up method, a relatively straightforward process to analyze diurnal variation, could replace the complex harmonic analysis. In addition, the maximum phase at six neutron monitors shows the 22-year cyclic variation very clearly. The maximum phase tends to appear earlier and increase the width of the variation in solar cycles as the cutoff rigidity increases.

Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

Objectives : Pal Hyue Hyul has been mentioned in $Nanky{\hat{o}}ng$ firstly and is a representitive acupoint of 8 parts of biological function of human body. The aim of this study is to finding out the process of formation of Pal Hyue Hyul. Methods : In this study we investigated and summarized all literetures from $Hwangjaenaeky{\hat{o}}ng$ to the today's papers which refer to Pal Hyue Hyul, and then basing on it, suggested our opinion about the correlation. Results & Conclusion : The results and conclusions obtained are as follow: 1. Pal Hyue Hyul is based on the Sahae theory of $Y{\hat{o}}ngchu$ and was formed in 45nan of $Nanky{\hat{o}}ng$. 2. Although Pal Hyue Hyul has been mentioned in $Nanky{\hat{o}}ng$ firstly, but because even $Nanky{\hat{o}}ng$ shows the quickening of Pal Hyue Hyul theory, the birth of Pal Hyue Hyul was necessary from the viewpoint of studing ambience. 3. About the reason for formation to 8 types, we think that all the biological functions of human body were represented as 8. 4. Pal Hyue theory had been suplemented and completed by annotations of successive medical men, for example the arguement about Golhyue, Suhyue. And the reason for the extent from the heat disease of the first phase to the associated disease is that it has been useful in the clinical treatment. 5. Because about whether Suhyue is Ch'imgol or $J{\hat{o}}lgol$, whether $J{\hat{o}}lgol$ is Yangbo(GB38) or $Hy{\hat{o}}njong(GB39)$, whether Golhyue is Teacu'u(GV14) or $Taej{{\hat{o}}}(BL11)$ there in no agreement of opinion among the successive medical men, much more study is necessary.

The objective of this study was to examine the effect of EGF on meiotic maturation and pronuclear (PN) formation of porcine oocytes. Prepubertal gilt cumulus-oocyte-complexes (COCs) aspirated from $2\~6mm$ follicles of abbatoir ovaries were matured in TCM199 containing 0.1mg/ml cysteine, $0.5{\mu}/ml$ FSH and LH, and EGF (0, 5, 10, 20, 40 ng/ml) for 22 hr at $39^{\circ}C$ in a humidified atmosphere of $5\%$ $CO_2$ in air. They were then cultured for an additional 22hr without hormones. In Experiment 1, to examine the nuclear maturation at 44hr of culture, the expanded cumulus cells were removed by vortexing for 1 min in 3 mg/ml hyaluronidase. The oocytes were fixed in acetic acid: methanol (1:3, v/v) at least for 48 hr and stained with $1\%$ orcein solution for 5 min. Nuclear status was classified as germinal vesicle (GV), germinal vesicle breakdown (GVBD), prophase-metaphase I (PI-MI), and PII-MII under microscope. In Experiment 2, to investigate PN formation, oocytes were fertilized with Percoll-treated freshly ejaculated sperm $(1\times10^5\; cells/ml)$ in mTBM with $0.3\%$ BSA and 2mM caffeine for 5hr, and cultured in NCSU-23 medium with $0.4\%$ BSA. At 6hr of culture, the embryos were fixed in $3.7\%$ formaldehyde for 48hr and stained with 10ug/ml propidium iodide for 30 min. PN status was classified as no or one PN (unfertilized), 2 PN (normal fertilized) and $\geq3$ PN (polyspermy). Differences between groups were analyzed using one-way ANOVA after arc-sine transformation of the proportional data. The rate of oocytes that had reached to PII-MII were significantly (P<0.05) higher in all groups added EGF than that of non-treated group $(67\%)$, but it did not differ among the all added groups $(86\%,\;85\%,\;79\%\;and\;81\%$, in 5, 10, 20 and 40 ng/ml EGF, respectively). No differences on the incidence of 2PN were observed in all treated groups $(25\%,\;30\%,\;33\%,\;29\%\;and\;29\%$, in 0, 5, 10, 20 and 40 ng/ml EGF, respectively), however, in non-treated group, polyspermy tended to be increased ($66\%\;vs\;. 58\%,\;54\%,\;52\%\;and\;55\%$, 0 vs. 5, 10, 20, 40 ng/ml EGF, respectively). These results suggest that EGF can be effectively used as an additive for enhancing oocyte maturation and reducing the incidence of polyspermy in pig.

Objective : This study was designed to evaluate the effect of moxibustion with various scales on symptoms of idiopathic Parkinson's disease. Methods : Subjects were voluntarily recruited by newspapers and internet. All the subjects are confirmed as idiopathic parkinson's disease by a neurologist. The moxibustion therapy was performed 5 times a week by patient's family at home and once a week by oriental medical doctor at hospital. Moxibustion points were GV2O, CV12, ST36, BL18, BL2O. Intensity was up to pain threshold according to patients not to get burned. The patient's symptoms were assessed before, after 4 weeks and after 8 weeks treatment by unified Parkinson's disease rating scale(UPDRS), modified Hoehn-Yahr(H-Y) stage, Schwab & England activity of daily living and freezing of gait questionnaire(FOGQ). Results : Total UPDRS scores were significantly improved after 4 weeks(p<0.01) and after 8 weeks(p<0.01) compared to the pre-treatment. There were significant changes in H-Y stage after 4 weeks(p<0.05), but there were no significant changes in H-Y stage after 8 weeks. The scores of ADL were not significantly improved after 4 weeks(p>0.05) and after 8 weeks(p>0.05). There were significant changes in FOGQ scale after 4 weeks(p=0.05) and but there were no significant changes in FOGQ scale after 8 weeks(p=0.13). Conclusion : This study suggests that moxibustion treatments can be applicable to improve symptoms in the patients with idiopathic Parkinson's disease.
