  • A characteristic of subtropical zones region MK-T2 compares with an gaeryangppong, and the 9-10 schedule the times when a leaf blooms to are fast, and ratio that a branch edge by the colds becomes lean showed 5.7%, and a growth of the new branch which went out delivers 67.2 cm, mulberry loaves of the new branch which went out, and 18.6, a form of a leaf is the 1.10 that length of a leaf grew more a bit than width of a leaf up. Thickness of a leaf is $228.2{\mu}m$, and an area is more similar than gaeryangppong as $225.6cm^2$. in plant taxonomy, the hair whom the style exists short with 0.7 mm, and go to the pistil head inside so as to be rare is distributed, and belong to Dolichostylae Pubescentes. The new branch cutting which executed without remedy processes was independent of a thickness of a case branch, and the form and 100% root was said, and an gaeryangppong compared with the fact that 10% root went out of 15 mm ideal, and was excellent very, and looked, a root went out a root the soil and water, all showed a characteristic to go out at central of a branch bases at 45% ratio. Length was 24.6 mm, and were water rate 78.8%, and mulberry of MK-T2 was carrying together sweetness and acidity to pH 4.7 while, besides, arrival was 19.21 Brix%. A larva period and pupa ratio, cocoon thickness ratio are almost similar to gaeryangppong, or weight of one cocoon, cocoon thickness, 20,002 cocoon quantity shows some results to drop, and be soft of a leaf, and feed value certifications are comparatively top-ranking. As a result of having analyzed amino acid of the 3rd day of 5th silkworm larva which bred to MK-T2, a collation absorbing an gaeryangppong went, and looked, but compared with a collation in case of tests to eat MK-T2, and looked, and the lie collations were not detected a difference at Leu, but MK-T2 tests were detected mutual almost similar amino acid creation. medical efficacy of the 3rd day of 5th silkworm larva ethanol extract which bred to MK-T2 and black results, histologic a case did not appear at HE dyeing about the kidney organization which extracted form the rats which ate a silkworm ethanol extract and dyeing all chemical organization immunity, and one step protein revelation became lower with almost unidentified levels.

  • Particulate matter is divided into PM10 (particle diameter of 10 ㎛ or less) and PM2.5 (particle diameter of 2.5 ㎛ or less), which are approximately 1/5 of the thickness of the hair. Due to its effect on the human body, lung disease, arteriosclerosis and heart It is known as a carcinogen that causes various diseases such as diseases. It is known that the main cause of such fine dust is nitrogen dioxide (NOx), which is emitted from automobiles in about 57.3% of urban roadsides. Therefore, in this study, as part of the development of functional construction materials to reduce NOx generated from road transport pollutants, comparative evaluation of NOx reduction performance was conducted according to the replacement rate of cement mortar in which cement was replaced with a porous material. In addition, the NOx reduction performance of cement mortar according to the photocatalyst application method and the number of applications was compared an d evaluated. As a result of the experiment, when activated ocher was substituted by 30%, it showed a reduction effect of about 32.7%, showing the best reduction performance.

  • The purpose of this study is to investigate the effects of the low power Helium Neon-Infra Red(HeNe-IR) laser and the special electromagnetic therapeutic apparatus stimulation, which is usually designated as TDP by using the initial of Tending Diancibo Pu which is the Chinese inscribed with English, on wound healing in rat. The seventy-five Sprague-Dawley adult female and male rats were assigned to the experimental and control groups. Each rat was anesthetized with pentobarbital sodium, and three full-thickness incisions with 12mm length wert made on the back of the half cf the rats and three deep second degree burns were made on the back of the remainder of the rats. From 34 hours after being injured, the rats of the experimental laser group were irradiated with the 157mW electric power HeNe-IR laser for 2 minutes every day and the rats of the experimental TDP group were stimulated with TDP irradiation with the 4km spot distance for 20 minutes every day during the 17 days. The rats were sacrificed and the wound parts of its were incised on the first day, 4th day, 7th day, 10th day and 17th day respectively after the beginning of wound treatment with laser and TDP irradiation. The incised wound parts were processed appropriately for the light microscopic and electron microscopic examination. The length of incised wound was measured with microcaliper before the wound part was incised. There was a significant decrease in the length of the incised wound of the experimental laser and TDP group, compared with that of control group at 4th day, 7th day and 10th day(p<0.01) after surgery. Through the histological examination of the wound site, the more rapid epithelialization and collagen formation in experimental groups were showed, compared with control group. The histological results were analyzed and summarized as the follows; The epidermis begins to be regenerated and the granulation tissue begins to be changed to the mature pattern in the H-E stained incised skin of the laser and TDP treatment group on the 4th day. The epidermis shows the complete regeneration and the granulation tissue in the dermis in mostly to be matured in the laser and TDP treatment group on the 7th day, compared with control group. The chronic inflammatory cells are oberved and the necrosis of the collagen fibers are partially observed in control group on the 10th day. The dermis of the laser and TOP treatment group reveals relatively compactly arranged collgen bundles with the mature collagen fibers on the 10th day. The epidermis and dennis of the laser and TDP group are repaired normally and the hair follicles are well regenerated on the 17th day. The mild edema and the granulation tissue is observed in the dermis of the control groups and the delayed treatment process is observed on the 17th day. The Most of proliferated collagen fibrils are found to be compact and regular in electron micrograph of burn skin of the laser treatment group on the 10th day hut the interstitial eadema and some inflammatory cells are found in the control group. The above results suggest that through the visual and histological examination the epithelized epithelium and the proliferation of the collagen liters in the dermis occur very effectively with the low power laser treatment and the TDP treatment in the incised wound healing and the burn wound healing.

  • Sangjeong was a sculptor-monk who was active in the mid-to-late 18th Century, and the current study established the overall chronology of Sangjeong's Buddhist statues and their styles based on the six sculptures of Sangjeong already known and the Wooden Seated Buddha of 1767 in Songgyesa Temple, Geochang, which was found to be his last work. All of the Buddhist statues of Sangjeong have commonalities in terms of the appearance of the ears, wrinkles on clothing on the upper and lower body, position of hands, and expression of the lower body. The expression of the lower body, in particular, is classified into three types: Type A, where the clothing drapes through the lotus leaves on the bottom; Type B, with an 'S-shaped' drape over the lower body but no lotus leaves or pedestal; and Type C, with the Buddha and pedestal as a single unit, and the clothing draping through the lotus leaves on the pedestal. It appears that Sangjeong faithfully succeeded the style of Taewon, who was his only instructor for sculpture. This is verified based on the records of his participation in the creation of the Wooden Seated Sakyamuni Buddha Triad and Statue of Arhat in Bongeunsa Temple, Seoul, as the third sculptor-monk out of twelve sculptor-monks, and the reflection of the S-shaped drape on the lower body found on the statue of Buddha in Bongeunsa Temple on all of the statues created by Sangjeong. Not only that, but it was assumed that the expression of the pedestal and hair was also inherited by Sangjeong from Taewon and Jinyeol, who was a sculptor-monk from the early 18th Century. The work of Sangjeong and Taewon showed differences in the volume and thickness of statues, strength of unevenness on the wrinkles of clothing, drapes on the right side of chest, and details of the ears. The current study identified the original styles of each individual sculptor and attempted to categorize the fourteen pieces of ten Buddhist statues reflecting the styles of Sangjeong into Sangjeong-style or Taewon-style.

  • The aims of the present study were to characterize the effect of glucocorticosteroids (GCs) on the normal canine skin and to evaluate the effect of a lipid mixture (LM), containing cholesterol, pseudoceramide, and free fatty acid, on the steroid-induced damaged skin of dogs. Five beagles were involved and the skin of the back of each dog was topically applied with four kinds of GCs twice daily for 28 days. LM was applied after that period of GCs application. Transepidermal water loss (TEWL), skin hydration, and skin pH were assessed during experimental periods and histopathological evaluation was performed. TEWL was significantly increased, with a maximum increase obtained on day 28 (p < 0.01). Skin pH was significantly decreased, with a maximum decrease obtained on day 28 (p < 0.01). Skin surface hydration was significantly increased on day 3, but values of skin hydration were progressively decreased and finally reached those of baseline. In histology, as results of steroid application, losses of keratin layers in the stratum corneum and edematous changes in the upper parts of dermis, and consequently, thickness of the epidermis and the stratum corneum were decreased. In addition, the numbers of hair follicles were markedly decreased in steroid control as compared to intact control. However, these skin atrophic changes were markedly inhibited by treatment of LM as compared with steroid control in the present study. Moreover, all biophysical parameters were reached to the baseline after LM treatment. These results showed that the topically applied GCs induced skin barrier impairment and a LM should be effective on repair of disturbed skin barrier function in dogs. Therefore, it is concluded that a LM tested in the present study is expected to treat the steroid-induced skin damages.
