  • Multi layered thin films with ZnS/$Na_3AlF_6$/ZnS were deposited on glass substrate by thermal evaporator precess and simulated by using EMP(Essential Macleod Program). EMP is a comprehensive software package to design and analyse the optical characteristics of multi-layered thin film. ZnS and $Na_3AlF_6$ were selected as a high refractive index and low refractive index material respectively. Additionally Cu was chosen as mid reflective material. Optical properties including color effect were systematically studied. in terms of different optical thickness of low refractive index material. The optical thickness of $Na_3AlF_6$ was changed as 0.25, 0.5, 0.75 and $1.0\lambda$. The film with 0.25, 0.5, 0.75 and $1.0\lambda$. of optical thickness showed mixed color range between bluish green and red purple, yellowish green and bluish green, purple and mixed color range of green and purple respectively.

  • This research was designed to study the Korean dress design trends and different kinds of ancient patterns applied to the Korean dresses in 2001. The trend sources were collected by the HANBOK monthly journal and the symbolism of patterns associated with these patterns being used the prevalent Korean dress collection in markets. The results of the research can be summarized as following; The most of Korean dress image was elegant of ancient mode. Main colors of the traditional Korean jacket were white, yellowish white and green. However, main color of the traditional Korean skirt was represented as red. A plant pattern was the most popular pattern in a practical purpose. It looks beautiful and it is also easily manufactured with open space. Copying other patterns definitely damage the elegance of the Korean dress. It is time for us to not only keep our own traditions but also study and develop new patterns. Designers must study to develop the image and patterns which are agreed with consumer's taste.

  • Background Xanthelasma palpebrarum (XP) is a benign disorder manifesting as yellowish cholesterol-laden plaques on the eyelids. This paper presents the outcomes in patients with XP who have undergone surgical excision as the main modality of treatment. Methods A retrospective review of patients who received surgery for xanthelasma palpebrarum from March 2007 to March 2011 was conducted. Patients were classified into four grades according to the location and extent of the lesion, with grade I being the mildest and grade IV being the most diffuse. Simple excision was performed in grade I and II lesions, while local flaps and skin grafts were performed in the more advanced grades. Results Ninety-five cases from March 2007 to March 2011 were included in this study. 66 cases (70%), were treated by simple excision. Twenty-four cases (25%) and 5 cases (5%) were treated by simple excision in combination with or without local flaps and skin grafts. In approximately 1/4 of the patients, orbicularis oris muscle involvement was observed. 4 patients (4.2%) developed scar contracture postoperatively, which required a secondary procedure. Recurrence was reported in 3 patients (3.1%). Otherwise. There were no other reports of major complications or disfigurement. Conclusions We found that for lesions involving the deep dermis and/or muscle, surgical excision was the most appropriate therapeutic option.

  • Gonadal development, gametogenesis, reproductive cycle, and first sexual maturity of Reishia clavigera were investigated monthly from July 1998 to June 1999 through cytological and histological observations. R. clavigera had separate sexes, and was an internal fertilizer. The ma1e penis was located near the two tentacles. The ovary and testis were composed of a great number of oogenic lobules and spermatogenic tubules, respectively. The size of ripe oocyte ranged from 130 to 140 ${\mu}$m in diameter. The peripheral cytoplasm of the germinal vesicle of the ripe oocyte in many cases were surrounded by smaller yolk granules, while the eccentric cytoplasm was occupied with larger ones. The reproductive cycle of R. clavigera could be classified into five successive stages: early active, late active, ripe, spawning, and recovery. Spawning of females occurred from early July to August when the seawater reached above 24.8$^{\circ}C$. Spawning of males occurred from early June to August in the water above 22.8$^{\circ}C$. Minimum size for sexual maturity of both sexes was above 10.0 mm in shell height. Each egg capsule was a cylinder or spindle in shape, 4-6 mm in length and 1-2 mm in width. Colors of newly spawned egg capsules showed yellowish white or pale yellow, while those with veliger larvae showed pale black, and released larvae or dead egg capsules showed black violet. The fecundity in an egg capsule ranged from 70 to 91 eggs (mean=80.28 eggs).

  • Colorants in green tea were extracted freeze-dried and analyzed to investigate the possibility of using as a natural dye. Fractionation of the colorants was carried out by column chromatograpy. Colorants in green tea were eluted into five fractions. All the fractions except fraction F2 showed absorption peakat 280nm. Fraction f2 showed absorption peak at 270nm and broad peak at 350nm, From the IR analysis it is speculated that fractions F2-F5 having similar stucture but different molecular weight are catechis. Silk fabrics dyes with fractions F1-F4 showed yellowish red color while sample dyed with fraction F5 showed red color. The colorants from green tea infusion was applied to silk wool nylon cotton and rayon fabrices. It showed relatively good affinity to protein and polyamide fibers bur low affinity to cellulose and regenerated cellulose fibers.

  • Decayed samples of marketed mungbean sprout were collected from Sacheon, Suncheon, and Dangjin cities in Korea. Initial symptom on hypocotyls was dark-brown diamond speck, which developed into enlarged sunken brownish-black spot with irregular margin, followed by softening yellowish decay. Brown speck on cotyledon further developed into irregular lesions. This study isolated the fungus Colletotrichum sp. The fungal colony was pale orange, which turned greenish gray after 1 week at $25^{\circ}C$. Colony of reverse side in a petri dish was pink. Neither conidiomata nor setae were present in the culture. Typical fusiform conidia sized 7.5-15.0$\times$2.5-2.9 $\mu\textrm$were hyaline, aseptate, smooth, and had salmon color in mass. Conidiogenous cells were phialidic, hyaline, smooth, and cylindrical with terminal distinct collarette. Basedon these mycological characteristics, the casual organism was identified as Colletotrichum acutatum. This is first report of Colletotrichum acutatum in Korea.

  • Idiopathic scrotal calcinosis is rare entity, characterized by the presence of multiple, firm nodules within the dermis of scrotal skin. The lesions are evident as asymptomatic, round, firm, yellowish papules, from several millimeters up to 1 cm in diameter, with a tendency to occur symmetrically. Because polypoid formation of the calcified cysts is unusual in scrotal calcinosis, we report our experience of a case of scrotal calcinosis with cysts having polypoid appearence. A 34-year-old man was admitted to our department with painless, firm, widespread nodules within the scrotum. Patient started to have these lesions at puberty and progressed to a polypoid form over time. There was neither surgical nor medical treatment had been attempted before our treatment. Physical examination revealed localized polypoid cysts in addition to multiple small, firm nodules within the scrotal skin. No underlying anomalies were detected in the physical examination and laboratory analysis. We experienced the treatment of polypoid idiopathic scrotal calcinosis and a case is presented with the review of literatures.

  • 12-month-old Buldig and 3-year-old German Shepherd, treated with corticosteroids duringthe late pregnancy, were referred to the Veterinary Teaching Hospital, Chonnam National University, with chief complaints of vaginal discharge. Radiographic, ultrasonographic and surgical findings that obtained from each cases were as follows; case I: Radiographic findings were identified 2 fetuses that were normal skeleton, however, fetal viability could not be determined. Ultrasonographic findings were identified absence of fetal heartbeat and fetal movement, abnormal echogenicity of the abdominal visera, and echogenic materials remaining within the fetal fluid. After hysterotomy, macroscopic findings of uterus were liquefied materials remaining within the uterine lumen. Fetuses were excessively autolysis (falling off the hair, depression of the eye, and necrosis of the abdormal visera and skin). case II: Radiographic findings were identified irregular fetal structures and fetal movement, loss of recognizable fetal anatomy, dislocation of fetal veterbrae and echogenic materials remaining within the uterine lumen. After ovariohysterectomy, macroscopic finding of uterus and fetus were thickened uterine wall, yellowish-brown colored administration of corticosteroids during gestation should be contraindicated because fetal death is inducced. Ultrasonography has an advantage over radiography in that it permits evaluation of fetal viability.

  • This experiment was performed to investigate apoptosis during undergoing patho-genesis of Salmonella gallinarum(SG)-infected chicks. 16 days old, 49 chicks was infected with SG (10$\^$6/-10$\^$8/ CFU/㎖) experimentally, they were autopsied to remove liver, spleen, intestine and lung at 1, 6, 12hr, 1, 2, 4 and 7 day post infection(PI) respectively, for H-E and TUNEL staining. Grossly, white foci in the liver and enlarged spleen were seen on 4 day PI and coppery bronze liver, dark-red discolored intestine, green-yellowish discolored and enlarged spleen was observed on 7 day PI. Histopathologically, multi focal necrosis in the liver, follicle hyperplasia in the spleen and inflammatory cells infiltration in the intestine were shown from 2 day PI and more severely observed on 4 day and 7 day PI. In TUNEL analysis, apoptotic cells reached a maximum at 6hr PI in the liver and intestine and at 12hr PI in the spleen, and then decreased the levels of controls by 7 day PI.
