Objectives The aim of this review is to figure out which acupoints are frequently used to treat low back pain and which exercises are effective to low back pain. Methods We searched the three electronic database (RISS, KISS, KTKP) and manually checked related Korean journals and reference lists up to June 2013. We investigated the frequency of acupoints for using treatment of low back pain. We Introduce exercise therapies we can do easily at home without professional skills for treatment low back pain. Results We included 72 articles in this study. The most frequently adopted acupoints were BL25, BL23, BL24, GB30, BL40, BL26, BL60, GB34, BL52, BL57, GB39. The most frequently adopted meridian pathways were BL, GB, GV, ST. The most frequently adopted disease causing low back pain were HIVD (Herniated intervertebral disc), Lumbar sprain, Spinal stenosis, Compression fracture, Cauda equina syndrome, Spondylolisthesis, Ankylosing spondylitis. There are many exercise therapies (Lumbar stabilizing exercise, Resistance exercise, Bareunmom physical exercise, Mckenzie exercise, Williams exercise, Emblass exercise, Swiss ball exercise, Thera band exercise, Yoga) for treatment low back pain. Conclusions These results suggest that most frequently adopted acupoints were foot taeyang urinary bladder channel acupoints. Beacuse foot taeyang urinary bladder channel is passes through the waist, it will be effective for treatment of low back pain. Also exercise therapy is effective for enhance Muscular strength. In order to treatment of low back pain, Acupuncture treatment is also important, as well as exercise therapy.

Objectives The purpose of this review is to investigate studies of Scolopendrid pharmacopuncture and the evidence of it's effects in order to suggest a better research method in the future. Methods We retrieved numbers of clinical studies about Scolopendrid pharmacopuncture from 7 Korean web databases, using key words such as 'Scolopendrid', 'Scolopendrid AND Pharmacopuncture'. This study had been conducted from 1st May 2013 to 31th July 2013. Controlled studies and case studies were only used for this study. Clinical studies that we picked from the databases were classified according to the diseases that those studies are about, and from these clinical studies, we are to research what has to be improved generally in clinical researches. Results 18 case studies, 4 controlled studies had been under research. Scolopendrid pharmacopuncture has a therapeutic effect mainly in musculoskeletal and neurological diseases such as herniated intervertebral disc, carpal tunnel syndrome, swollen leg, feeling of cold on legs, wrist ganglion, lateral epicondylitis, radial nerve palsy, cervical myelopathy, cauda equina syndrome, postauricular pain; as an early symptom of Bell's palsy, pain of popliteal part, gout, plantar fasciitis, cellulitis, frozen shoulder, pain of hip adductors. However objectivity and reliability of the Scolopendrid pharmacopuncture studies still remains controversial. Conclusions It has been suggested that there are positive effects of Scolopendrid pharmacopuncture therapy in treating specific diseases (especially neuromusculoskeletal diseases). However, this narrative review can't conclude and prove that the Scolopendrid pharmacopuncture has positive effectiveness on these diseases unlike systematic review. So, in order to put Scolopendrid pharmacopuncture therapy to use for many kinds of diseases in more reasonable ways, it is essential to build well-designed clinical research tools. In the future, abundant case studies, more follow-up trials and randomized controlled trials based on the korean medicine should be done to use Scolopendrid pharmacopuncture for a clinical purpose.

Most investigators recommended that porcelain surface should be roughened with abrasives and/or be etched with acid in repairing the fractured porcelain with composite resin. This study was designed to evaluate the effect of porcelain surface treatments on the bond strength between porcelain and composite resin by measuring the shear bond strength and observing the porcelain surface with SEM. 48 porcelain disc were fabricated with Vintage porcelain and embedded in epoxy resin with the test surface exposed. The specimens were divided four groups at random and the test surfaces of the four groups were prepared as follows : Group 1 : Porcelain surface was roughened with a fine diamond and treated with 32% phosphoric acid gel for 10 seconds. Group 2 : Porcelain surface was roughened with a fine diamond and etched with 8% hydrofluoric acid gel for 5 minutes. Group 3 : Porcelain surface was roughened with a coarse diamond and treated with 32% phosphoric acid gel for 10 seconds. Group 4 : Porcelain surface was roughened with a coarse diamond and etched with 8% hydrofluoric acid gel for 5 minutes. All specimens were washed for 30 seconds. A representative specimen of each group was selected and the porcelain surface was observed with SEM at 1000 magnification. Remaining specimens were silanated, bonded with composite resin, thermocycled, and shear-tested on specially designed zig connected to Instron machine. The results were as follows : 1. The shear bond strength of the group etched with hydrofluoric acid was significantly higher than that of group treated with phosphoric acid(p<0.01). 2. The shear bond strength of the group roughened with a fine diamond was not significantly different from that of the group roughened with a coarse diamond(p>0.01). 3. SEM examination of prepared porcelain surfaces revealed that the surface etched with hydrofluoric acid showed numerous microporosities, undercut, and rougher surface than the surface treated with phosphoric acid. 4. All specimens etched with hydrofluoric acid showed cohesive failure within porcelain, but specimens treated with phosphoric acid mainly showed adhesive failure between porcelain and composite resin.

Statement of problem: When an implant is fixed, a fixture comes into contact with a tissue fluid. Adhesion of a tissue fluid to a surface of implant is various case by case. Purpose: The ultimate goal of this work is to analyze a correlation between a surface roughness and wettability of implant specimens. A measurement for wettability is performed considering 4 types of specimen implant with surface treatments different from each other to investigate the change of wettability with the elapse of time. Material and methods: Firstly, 20 specimens of titanium were prepared. The specimen were made of a commercial Titanium Grade IV with the diameter of 10 mm and the thickness of 1 mm. According to the method of surface treatment, the specimens were classified into 4 groups of 5 specimens per group. Group A: Machined Surface Group B: Anodized surface Group C: RBM (HA blasting) surface Group D: CMP (calcium methaphosphate) coating surface. Surface roughness of specimen was measured using SV-3000S4 (Mituyoto, Japan). The measurement was based on the standard of JIS1994. Sessile drop method was used to measure the wettability, which measures contact angle between implant disc and saline with the time interval of 5, 10, and 15 seconds. SPSS 11.0 was used to analyze the collected data. In order to analyze the difference of wettability and surface roughness according to implant surface treatment method. The statistical significance was tested with the confidence level of 95%. Pearson's correlation coefficient was used to evaluate the correlation of surface roughness and wettability. Results: The difference of surface roughness was statistically significant in the order of Group C ($1.69{\pm}0.26$), Group D ($1.58{\pm}0.16$), Group B ($0.78{\pm}0.14$) Group A ($0.18{\pm}0.05$). The wettability has also a statistically significant difference, which was in the order of group B ($17.70{\pm}2.66$), Group C ($27.86{\pm}4.52$), Group D ($66.28{\pm}3.70$) Group A ($70.52{\pm}8.00$). There was no difference in wettability with the passage of time. Conclusions: 1. The surface roughness was high in the order of RBM, CMP, Anodized, Machined group (P<.05). 2. The wettability was high in the order of Anodized, RBM, CMP, Machined group (P<.05). 3. There was no statistical significance in the correlation of surface roughness and wettability.

The purpose of this study was to evaluate the effects of exposure to various children's drinks on the color stability of anterior primary teeth and different esthetic restorative materials clinically used in pediatric dentistry. Exfoliated maxillary primary central incisors that had been unaffected by caries were chosen as control group. Maxillary primary central incisor-shaped specimens made of strip crown and Nu-smile zirconia crowns were chosen as test groups. Polished strip resin crowns were additionally prepared to compare with unpolished strip resin crown. Each specimen and teeth were divided into 4 groups in which the test samples (n=5 each) were immersed in 4 different drinks (distilled water, cola, grape juice, jelly juice) for 6 days. In all 4 drink groups, all specimens generally showed increasing ${\Delta}E^*$ value (color difference) with time. Polished resin strip crown had higher ${\Delta}E^*$ value than the unpolished in cola, grape juice and jelly juice groups. ${\Delta}E^*$ value of zirconia crown in cola, grape juice and jelly juice groups were significantly different (p < 0.05). In conclusion, dietary control of children's drinks is required for preventing discoloration of restorative materials.

Guava (Psidium guajava L.) contains high amount of vitamins and minerals, and its leaves have been reported to be very effective on reducing blood pressure. In this study, antimicrobial characteristics of extracts from four different parts of guava (fruit, branch, leaf, and seed) with four different solvents (methanol, ethanol, acetone, and water) were evaluated. Four targeted food-borne microorganisms were selected; two Gram negatives (Escherichia coli O157:H7 and Salmonella Typhimurium) and two Gram positives (Staphylococcus aureus and Listeria monocytogenes). By the paper disc method, guava extracts showed stronger clear hollow zone against Gram positive bacteria than Gram negatives in nutrient broth agar plate. Especially, extracts of branches and leaves showed significant antibacterial activity. Guava extracts also showed significant inhibition activity on the growth of Gram positive food-borne bacteria in nutrient broth. For example, S. aureus did not grow at all at 200 ppm of acetone extracts of guava branch and leaf. In the case of L. monocytogenes, the same concentration of acetone extracts of guava branch and leaf inhibited the growth 33.5% and 55.4%, respectively, at 32 hrs of incubation time. The results indicated that extracts of guava branch and leaf showed significant antibacterial activities against food-borne Gram positive microorganisms, and that guava branches, the byproducts of guava, might be a valuable resource for antibacterial materials.

Many studies have done on Egyptian Clothing because its unique characteristic culture. However, I was facinated by the exhibitions of Tutankhamen burial treasures which were shown in San Francisco and New York in 1978 and 1979. I found out myself that there are several interesting aspects of clothing to compare 18th dynasty king, Tutankhamun and other dynasties in Egyptian culture. Therefore, I tryed to analized the Egyptian clothing including accessaries with theigr symbols durin 18th dynasty King, Tutankhamun. The most of people were shocked and amazed when they toured the exhibition of Tutankhamun articles which were the most incredible burial treasures in existence today. The body of the King has been embalmed, bandaged and fitted in eight layers of coffins with pure gold mask to represent the god Osiris. Among eight layers of coffins, one is pure solid gold in mummiform, two of mummiforms are made of compact wood covered with sheets of gold and inlaid with multi-colored glass-paste and semi-precious stones. The Egyptian belived that the soul continued to exist throughout eternity if it had passed on examination of its deeds on earth at a "Last Judgement" presided over by Osiris. They also believed that the mummified body could exist in the tomb as a habitation that the soul could revisited. Thus a proper burial was vital for a full existence in the hereafter. They buried dead person in the sealed vault of the tomb with some of the possessions he had used during his life time, such as his furniture, clothing and jewels. In this studies, I've tried to research to various clothings, and accessories with their symbols used during 18th dynasty king, Tutankhamun. The studies are shown as: I) Clothings of Tutankhamun dynasity of Kalasiris, Sheath skirt. Gala skirt, Loin skirt, Hike and Dalmatic. The Dalmatic was first seen in this dynasty. Probably the Roman Christian borrowed the Dalmatica from Egyptian Dalmatic. No where has the same design at the period. II) Egyptian of 18th dynasty Tutankhamun wore big headdress, broad collar necklace passium, pendants, armlets, rings and earrings with very beautiful, exquisite handcraft. They seem the first people who wore earrings in Egyptian history. III) The symbols of decorated items vulture, lotus...Upper Egypt Uraeus, papyrus...Lower Egypt scaravaeus, Nile Riber...rebirth man(Ankh), +...eternal life solar disc, gold...sun ostrich-feather...nobleness God, Horus' eye...protection against enemy IV) Also Egyptian prefered the straight line and a right angle which were the basic principles of architectural arrangement.

The antimicrobial activity of 10 different traditional medicinal herbs extracts against E. coli was determined using paper disc method. Caesalpinia sappan and Rhus javanica, extracts in 5 mg/ml, and Paeonia suffruticosa and Seutellaria baicalensis extracts in 10 mg/ml showed significant antimicrobial activity against E. coli. Minimum inhibitory concentrations of medicinal herbs extracts were in the range of $1.4{\sim}8mg/ml\;and\;1.2{\sim}12mg/ml$, for MeOH extracts and EtOH extracts, respectively. In addition, the antimicrobial activity of each solvent fraction was most significant with the EtOAc layer. Optical density at 620nm after 24 hours incubation of E. coli in the presence of 100, 300 or 500 ppm of Caesalpinia sappan extract ranged from 0.02 to 0.1 compared to 0.6 in the absence of Caesalpinia sappan extract, indicating that growth of E. coli was significantly inhibited within 24 hours by the addition of at least 300 ppm of Caesalpinia sappan extract. Optical density at 620 nm after 24 hours incubation of E. coli in the presence of 300 ppm of Rhus javanica extract ranged from 0.02 to 0.2 compared to 0.5 in the absence of Rhus javanica extract, indicating that growth of E. coli was also significantly inhibited within 24 hours by the addition of at least 500 ppm of Rhus javanica extract. In conclusion, these findings suggest that extracts from medicinal herbs may play important roles in antimicrobial activities against E. coli.

Objective : Spondylothesis is a disease which sagittal facet of vertebral body's invariable alignment is being broken and vertebral body being pushed forward. Main pattern of spondylothesis is isthmic spondylothesis by isthmus defect or fracture, degenerative spondylothesis occurred by desiccated change of intervertebral disc or vertebral condyle joint's ligament. The purpose of this study is to assess the difference of the Pelvic angles, Lumbosacral angles, Pelvic tilt, and Lumbar lordotic angles of the spondylothesis patients. Methods : We analyzed the lateral view of lumbar spine of 49 isthmic spondylothesis patients, 45 degenerative spondylothesis patients and 26 patients who haven't been diagnosed as vertebra disease. We investigated each patient's pelvic angle, lumbosacral angle, pelvic tilt and lumbar lordotic angle. Results and Conclusion : 1. Pelvic incidence, in cases of degenerate spondylothesis patients, is higher than spondylothesis patients but shows less significance. On the contrary significance is higher than the group haven't been diagnosed as vertebra disease. 2. Lumbosacral incidence, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 3 Pelvic tilt, in cases of degenerative spondylothesis patients, shows higher significance than isthmic spondylothesis patients and the group haven't been diagnosed as vertebra disease. 4. Lumbar lordotic angle, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 5. Degenerative spondylothesis patient shows specific impression, a forwardly moved high femoral axial and as a result of large lumbrosacral angle and lumbar lordotic angle shows specific impression, an increased weight pressure on sacrum.
