Objective: To investigate the changes of facial temperature by Miso Facial Rejuvenation Acupuncture treatment. Methods: One middle-aged women who has no other disease was recruited. The Miso Facial Rejuvenation Acupuncture was performed on only right face. We measured the facial temperature using the Digital Infrared Thermal Imaging (DOREX Inc. Spectrum 9000 MB, USA, D.I.T.I.) before, immediate after and 10 minutes after treatment. And we used the Wilcoxon signed rank test (P<0.05) to compare the difference of facial temperature at each time. Results: Right facial temperature (the area treated by acpuncuture) increased immediately from $30.02{\pm}1.87^{\circ}C$ to $32.24{\pm}1.03^{\circ}C$, the change of temperature is statistically significant. At 10 minutes after treatment, right facial temperature decreased little, but there was no statistical significance. Left facial temperature increased little, but there was no statistical significance. The difference between right and left face increased after Miso facial rejuvenation acupuncture treatment. Conclusion: Miso facial rejuvenation acupuncture could make the facial temperature increase.

Objectives : To investigate changes in facial temperature generated by Miso Facial Rejuvenation Acupuncture treatment. Methods : One middle-aged woman with no diseases was recruited. Miso Facial Rejuvenation Acupuncture was performed on only the right side of her face. We measured her facial temperature using digital infrared thermal imaging(DOREX Inc. Spectrum 9,000MB, USA, D.I.T.I) before, immediately after, and 10 minutes after treatment. We also used the Wilcoxon signed rank test(p<0.05) to compare the differences in facial temperature from one side of the face to the other at each time. Results : Facial temperature on the right side(the area treated by acupuncture) increased immediately from $30.02{\pm}1.87^{\circ}C$ to $32.24{\pm}1.03^{\circ}C$, a statistically significant increase. Ten minutes after treatment, facial temperature on the right side decreased a little bit, but there was no statistical significance. Facial temperature on the left side increased a little, but there was no statistical significance. The difference between the right and left sides of the face increased after the Miso Facial Rejuvenation Acupuncture treatment. Conclusions : Miso Facial Rejuvenation Acupuncture could increase facial temperature.

The CHCl₃ fraction of the MeOH extract of Ganoderma gibbosum (Ganodermataceae) exhibited cytotoxic activity on five cancer cell lines (MDA-MB-231, SK-hep1, A549, HCT116, and SNU638). Six highly oxygenated lanostane-type triterpenoids (lanostanoids) were isolated by column chromatography to test cytotoxicity on cancer cells. The five known lanostanoids were identified as gibbosic acids A, B, D, G, and H by comparison of molecular ion peaks with the literature data. The structure of a new lanostanoid, gibbosic acids I, was identified to be 3β,8β,15β,20S-tetrahydroxy-7,12,23-trioxolanost-9(11)-en-26-oic acid on the basis of NMR and MS spectroscopy. The three lanostanoids of gibbosic acids A, H, and I of the six isolates significantly suppressed the growth of cancer cells. In particular, the IC₅₀ of gibbosic acid H was prominently low ranging from 2.64-6.56 μM.

The sensory characteristics of bread prepared with the addition of Angelica plant(Bakluncho) and Jujube(Daechu) powders were investigated The moisture, crude protein, as reducing sugar and vitamin C content of Angelica plant(Bakluncho) powders were 7.78%, 6.07%, 7.37%, 6.13% and 50.10 mg% respectively, and those of Jujube(Daechu) powders were 11.19%, 4.43%, 2.36%, 14.23% and 49.20 mg% respectively. Lightness value decreased but redness and yellowness values increased with increasing natural pigment powders content. The mechanical hardness of the bread decreased with the addition of 3% Angelica plant(Bakluncho) powders, but increased with the addition of 1% and 5% Angelica plant(Bakluncho) powders. The mechanical hardness of bread decreased with the addition of 1% and 3% Jujube(Daechu) powders, but increased with the addition of 5% Jujube(Daechu) powders. In sensory characteristics, the crust color, mb color, moistness and springiness decreased, but aroma and hardness increased with the increasing natural pigment powders content. The savory taste and overall quality of breads with 1% Angelica plant(Bakluncho) powders and 3% Jujube(Daechu) powders were higher than those of the control without my addition. A negative correlation was observed between Hunter's color value and overall quality of the bread prepared with addition of Angelica plant(Bakluncho) and Jujube(Daechu) powders.

Powered activated carbon(PAC) has been widely applied for controling odor causing compounds(OCCs) from water treatment plants. Because of their volatility, the OCCs can also be removed from water by air stripping methods. In this study, OCCs removal was tested with PAC adsorption, air stripping, and both PAC adsorption and air stripping from the Taecheong lake water. Removal efficiency of OCCs in terms of threshold odor number(TON) were 39.6% by both PAC (15mg/L) adsorption and aeration for 30 min, 33.6% by PAC(15mg/L) adsorption alone for 30 min, and 22.9% by aeration alone for 30 min, respectively. OCCs could be removed up to 50% by aeration for 120 min without PAC adsorption. At an extended aeration with 15mg/L of PAC, OCCs removal occurred mainly by PAC adsorption within 30 min aeration while it continued by air stripping afterward. At simulated jar tests with the raw water, removal efficiencies of geosmin and MIB were 48.3, 36.1% by coagulation and sedimentation without PAC addition. With 15mg/L of PAC on the same jar tests, the removal efficiencies were 83.1, 60.1%, respectively. Without PAC, OCCs could be possibly removed by stripping during the agitation processes.

A flue-cured tobacco variety (Nicotiana tabacum cv. Wisconsin) was used for Plant transformation with the complementary DNA (cDNA) of potato virus Y-necrosis strain (PVY-VN) replicase gone (Nb) which was synthesized through reverse-transcription Primed with oligo(dT) and Polymerization using RNase H-digested template. The cDNA was cloned into Plant expression vector Plasmid (PMBP2), and introduced into tobacco plants by co-culturing tobacco leaf disks with Agrobacterium tumefaciens LBA4404 containing the plasmid before Plant regeneration. Eight Plants, in which the inserted cDNA fragment was detected by Polymerase chain reaction (PCR), out of 70 putative transformants inserted with sense-oriented Mb cDNA showed no symptom at 3 weeks after inoculation, while the other 62 plants, and all plants with vector gone only and antisense-oriented NIb cDNA had susceptible vein-necrosis symptoms. However, only 2 of the 8 resistant plants were highly resistant, which remained symptomless up to 10 weeks after inoculation. Among the first progenies (T1) from self-fertilized seeds of the two resistant transgenic plants, less than 10 % of 71 plants appeared highly resistant (with no symptom), 70% moderately resistant (with mild symptoms on 1 - 2 leaves), and about 20% susceptible (with susceptible symptoms on 3 or more leaves) at 3 weeks after inoculation. These results suggest that the PVY resistance was inherited in the 71 generation. Key words : potato virus Y. viral replicase gene, transgenic tobacco Plants, resistance.

WAGR (Wilms tumor, aniridia, genitourinary anomalies, and mental retardation) syndrome is a rare contiguous gene deletion syndrome caused by deleting genes including WT1 and PAX6 genes in 11p13 region, which is characterized by Wilms tumor, aniridia, genitourinary abnormalities, and intellectual disability. We report the clinical and cytogenetic characteristics of one Korean patient with WAGR syndrome. The patient shows bilateral sporadic aniridia and genital anomalies at 2 months of age. A heterozygous 14.5 Mb interstitial deletion of 11p14.3p12 region was detected by array comparative genomic hybridization. At 2 years and 10 months of age, Wilms tumor is found through regularly abdominal ultrasonography and treated by chemotherapy, radiation therapy and surgery.

This paper analyzes the performance of an optical line termination system in ATM based Passive Optical Network(PON) using the operational analysis. We analyze it using system parameters such as utilization, throughput and routing frequency based on the buffer structure in each block of ATM-PON. Furthermore, we derive the mean response time and the visit ratio of each block, and then search the bottleneck block that hinders the system performance. We found that the 622Mbps 16x16 switching block is the bottleneck block for ATM-PON. In this bottleneck block, the loss probability increases rapidly when the cell arrival rate increases.

As the regulations on DBPs are tightened, many water treatment plants (WTPs) in Korea have already introduced or will introduce enhanced coagulation, alternative disinfectants and advanced treatments such as ozonization and granular activated carbon to improve drinking water qualify. After a phenol leakage accident at the Nakdong-River in 1991, 26 WIPs in Korea introduced carbon dioxide generators, but there has been no accumulation of significant operating data. This research summarizes things that should be considered for the introduction of carbon dioxide disinfection process to WTPs based on one year operation data from A WTP that has had high concentration of DBP during a specific period in the summer. The removal efficiency of DBP was $30{\sim}40%$, but those of 2-MIB, Geosmin were less than 10%. The generation rate of $ClO_2$ by-products such as chlorite and chlorate were $70{\sim}100%$ of input dosage, but the ratios increased over time. At the same time, strong chlorine odors may be produced in the distribution system when $ClO_2$ was used with $Cl_2$ as a result of reaction between the chlorite and residual chlorine.

This study was aimed to evaluate the cavernosal relaxation effect of Crataegii fructus(CF) in the contracted rabbit penile corpus cavernosum by agonists.In order to study the effect of CF on the vasoconstriction of rabbit penile corpus cavernosum, isolated rabbit penile corpus cavernosum tissues were used for the experiment using organ baths containing Krebs solution.To investigate the cavernosal relaxation of CF, CF extract at $0.01{\sim}3.0mg/m{\ell}$ was added after penile corpus cavernosum were contracted by norepinephrine(NE) $1{\mu}M$. To analyze the mechanism of CF's vasorelaxation, CF extract infused into contracted penile tissues by NE after each treatment of indomethacin(IM), $N{\omega}$-nitro-L-arginine(L-NNA), methylene blue(MB), tetraethylammonium chloride(TEA).To study the effect of CF on influx of extracellular calcium chloride($Ca^{2+}$) in penile tissues, in $Ca^{2+}$-free krebs solution, $Ca^{2+}$ 1 mM infused into contracted penile tissues by NE after pretreatment of CF. Cytotoxic activity of CF on human umbilical vein endothelial cell(HUVEC) was measured by MTT assay, and nitric oxide(NO) prodution was measured by Griess reagent. CF relaxed cavernosal strip with endothelium contracted by NE, but in the strips without endothelium, CF-induced relaxation was significantly inhibited. The pretreatment of L-NNA, MB, TEA decreased significantly on the cavernosal relaxation than not-treatment of them. But the pretreatment of IM had no significant effect on the cavernosal relaxation. In $Ca^{2+}$-free krebs solution, when $Ca^{2+}$ infused into contracted penile tissues by NE, pretreatment of CF inhibit contraction induced by adding $Ca^{2+}$.NO production wasn't increased by treatment of CF on HUVEC. This findings showed that CF is effective for the relaxation of rabbit penile corpus cavernosum, and we suggest that CF relax rabbit corpus cavernosal smooth muscle through multiple action mechanisms that include increasing the release of nitric oxide from corporal sinusoidal endothelium, inhibition of $Ca^{2+}$ mobilization into cytosol from the extracellular fluid, and maybe a hyperpolarizing action.
