  • Objective : The aim of this experiment is to investigate the effect of acupuncture and moxibustion at SP6(Sanyinjiao) and BL28(Pangguanshu) on uranyl acetate-induced acute renal failure in rats. Methods : To induce experimental acute renal failure, uranyl acetate was intraperitoneally injected to rats by 5mg/kg. 3 days later acupuncture and moxibustion treatment was done at SP6(Sanyinjiao) and BL28(Pangguanshu) bilaterally of the rats. And then 4 days later, we measured rats' body weight, kidney weight, serum BUN, creatinine and serum eletrolyte levels(Na, K and Cl). Results : In the moxibustion group, hypertrophy index of kidney and serum BUN level were decreased marginally significantly, and serum creatinine, K levels were decreased significantly. But in the acupuncture group, there was no significance at this experiment. Conclusions : SP6(Sanyinjiao) and BL28(Pangguanshu) moxibustion can decrease serum BUN, creatinine, and serum eletrolyte levels on uranyl acetate-induced acute renal failure in rats. And the study will be done continuously about non-effect in the acupuncture group at this experiment.

  • Nb and Ti were added to 316 stainless steel, and then heat-treatments and surface treatments were performed on the 316 stainless steel and the Nb- and Ti-added alloys. All samples indicated enhanced electrical conductivity after surface treatments, whereas they showed low electrical conductivity before surface treatments due to the existence of non-conductive passive film on the alloy surface. In particular, the Hb- and Ti-added alloys showed remarkable enhancement of electrical conductivity compared to the original alloy, 316 stainless steel. Surface characterization revealed that small carbide particles formed on the alloy surface after surface treatments, while the alloys indicated flat surface structure before surface treatments. $Cr_{23}C_6$ mainly formed on the 316 stainless steel, and NbC and TiC mainly formed on the Nb- and Ti-added alloys, respectively. We attribute the enhanced electrical conductivity after surface treatments to the formation of these carbide particles, possibly acting as a means of electro-conductive channel through the passive film. Furthermore, NbC and TiC are supposed to be more effective carbides than $Cr_{23}C_6$ as electro-conductive channels of stainless steel

  • On the assumption that marketing is a useful technique to activate park use, this study aims to find what benefits people pursue and how much they attain them through a park visit. To achieve this, the survey of a Benefits-Sought for a park was conducted at four major parks in the city of Taejon and an Importance-Performance Analysis(IPA) was conducted. Additionally, a Present Condition survey was performed with the park managers. As a result, first, it was found that major benefits are a comfortable rest, an escape from bustling city life, to see natural scenery and to promote physical health, and so forth. Second, performance was relatively lower than importance in the case of recreation and leisure activities, which means that facilities should be improved and programs for park use should be developed. Third, at GaYang park, importance and performance are good in balance. DongChunDang park and Seattle park have 5 items and 7 items for which immediate improvements are required. Saemmeury park generally shows good proportions and it can be much activated by improving the learning and experiencing activities. The results objectively show conditions of neighborhood parks in the city of Taejon from a view of park users. Therefore, it is expected that the results would be useful in determining priorities when improving park facilities or their programs.

  • This paper reports the efficacy of tape casting using an Ag-10 wt% CuO filler for the successful joining of a sintered $Ce_{0.9}Gd_{0.1}O_{2-{\delta}}-La_{0.7}Sr_{0.3}MnO_{3{\pm}{\delta}}$ (GDC-LSM) ceramic with a SUS 460 FC metal alloy by reactive air brazing. The as-prepared green tape was highly flexible without drying cracks, and the handling was easy when used as a filler material for reactive air brazing. Heat treatment for the GDC-LSM/SUS 460 FC joint was performed at $1050^{\circ}C$ for 30 min in air. Microstructural observations indicated a reliable and compact joining. The room temperature mechanical shear strength of the as-brazed joints was $60{\pm}8MPa$ with a cohesive failure. The flexural strength of joints was measured from room temperature up to $850^{\circ}C$, where the strength retention revealed to be almost 100% at $500^{\circ}C$. However, the joints showed a degradation in strengths at 800 and $850^{\circ}C$, exhibiting strength retentions of 57% and 37%, respectively.

  • By studying from Chun Kuk are(戰國時代) to Chung area(淸代), I could find some conclusion as follows. 1. It was Chun Kuk area(戰國時代) that was shown some signs of forthcoming activity of theory of Ki Kyung Pal Maek(奇經八脈). In that time, Hwang Jae Nae Kyung(黃帝內經) had been written. That book made a important role for foundation of theory of Ki Kyung Pal Maek(奇經八脈), but it hadn't sufficient contents in some parts. 2. The theory of the Ki Kyung Pal Maek (奇經八脈) had been developed in Jin Han area(秦漢時代), Nan Kyung(難經) had been written in the area, Nan Kyung(難經) had been the first book which had referred to name and physiology of Ki Kyung Pal Maek(奇經八脈) and it also had mentioned about course, function, and pathology of that in simple manner. 3. In Yang Jin are and Su Dang area(兩晋 및 隋唐時代), Maek Kyung(脈經) and Hwang Jae Nae Kyung Tae So(黃帝內經太素) had been written Maek Kyung(脈經) had been the first book which had referred to pathology of Ki Kyung Pal Maek(奇經八脈) by Maek Jin(脈診) in detail, and it had affected on such books like Tae Pyung Seoung Hveu bang (太平聖惠方) and Ko Kum Yeu Tong Dae Chon(古今醫統大全). Hwang Jae Nae Kyung Tae So(黃帝內經太素) had mentioned about course, function, and pathology about Ki Kyung Pal Maek(奇經八脈) in most detail at that time, and it also had referred to that of such books like Myung Dang(明堂) and Ku Khoun Kyung(九卷經) which do not exist in present. Because of these point, Hwang jae Nae Kyung Tae So(黃帝內經太素) is evaluated an important book of theory of Ki Kyung Pal Maek(奇經八脈). 4. In Song area(宋代), Seung Jae Chong Rok(聖濟總錄) had been written. Seung Jae Chong Rok(聖濟總錄) first mentioned about meeting between Ki Kyung Pal Maek(奇經八脈) and Sip I Jong Kyung(十二正經), so this book helped development of theory of Ki Kyung Pal Maek(奇經八脈) of Kum Won area(金元時代). 5. In Kum Won area(金元時代), Dong In Su Hyul Chym Ku Do Kyung(銅人腧穴針灸圖經) had been written. Dong In Su Hyul Chym Ku Do Kyung(銅人腧穴針灸圖經) made a important role of theroy of Im Meak(任脈) and Dok Meank(督脈). Sip Sa Kyung Bal Hyui(十四經發揮) was superior to other books which had been referred to theory of Ki Kyung Pal Maek(奇經八脈) at that time. Also Sip Sa Kyung Bal Hyui(十四經發揮) more mentioned about meeting between Ki Kyung Pal Maek(奇經八脈) and Sip I Jong Kyung(十二正經) than that of Seung Jae Chong Rok(聖濟總錄), so this book helped dvelopment of theory of Ki Kyung Pal Maek(奇經八脈). 6. In Myung area(明代), Ki Kyung Pal Maek Ko(奇經八脈考) that had almost accomplished theory of Ki Kyung Pal Maek(奇經八脈) had been written. Ki Kyung Pal Maek Ko(奇經八脈考) was the best book more than any other book that had been mentioned about theory of Ki Kyung Pal Maek(奇經八脈) in three ways as follows. 1) It is Ki Kyung Pal Maek Ko(奇經八脈考) that mentioned about near similar manner of modern course and physiology of Ki Kyung Pal Maek(奇經八脈). 2) Ki Kyung Pal Maek Ko(奇經八脈考) mentioned about pathology and treatment of Ki Kyung Pal Maek(奇經八脈) in detail more than any other book. 3) Ki Kyung Pal Maek Ko(奇經八脈考) emphasized on relationship between Ryun Kong(鍊功) and Ki Kyung Pal Maek(奇經八脈).

  • Ibudilast, 3-isobutyryl-2-isopropyrazolo[1,5-a]pyridine, is a nonselective inhibitor of cyclic nucleotide phosphodiesterase (PDE). It preferentially inhibits PDE 3A, PDE4, PDE10 and PDE11 as well as a number of the other PDE families, albeit to a lesser extent. Ibudilast is used clinically to treat bronchial asthma and cerebrovascular disorders. Thes e clinical uses are based on the ability of ibudilast to inhibit platelet aggregation, improve cerebral blood flow and attenuate allergic reactions. The purpose of the present study was to evaluate the bioequivalence of two ibudilast capsules, Ketas capsule (Handok Pharmaceuticals Co., Ltd.) and Pinatos capsule (Sam Chun Dang Pharm. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The in vitro release of ibudilast from the two ibudilast formulations was tested using KP Apparatus method with various dissolution media. Twenty six healthy male subjects, 23.31${\pm}$1.09 years in age and 70.45${\pm}$8.51 kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After a single capsule containing 10 mg as ibudilast was orally administered, blood samples were taken at predetermined time intervals and the concentrations of ibudilast in serum were determined using HPLC/UV detector. The dissolution profiles of two formulations were similar in all tested dissolution media. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated, and computer programs (Equiv Test and K-BE Test 2002) were utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, Ketas, were 6.99%, -2.48% and 9.93% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 (e.g., log 0.8791~log 1.1861 and log 0.8347~log 1.1199 for $AUC_t$ and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Pinatos capsule was bioequivalent to Ketas capsule.

  • Crude methanolic(80%) extracts from 109 kinds of traditional herbal drugs were randomly screened for inhibitory effects on 5-hydroxytryptamine(5-HT) uptake in primary cultured rat brainstem neurons. Rat brainstem neurons were cultured from embryonic day 14, and maintained for 7-9 days in vitro. Clomipramine (500 nM), a reference drug, decreased 5-HT uptake to 16% of control values. Of the 109 herbal drugs screened, Citri immaturi Pericarpium(靑皮), Coptidis Rhizoma(黃蓮), Cnidii Rhizoma(土川芎) showed the most potent 5-HT uptake inhibiting activities. These herbal drugs, at the concentration of $10{\;}{\mu}g/ml$, inhibited 5-HT uptake 69, 69, and 57% respectively, when inhibition(%) was expressed as a relative value compared to the 500 nM clomipramine-induced inhibition.
