  • This study is related to the preparation of biocompatible gold nanoparticles (AuNPs) which are stable in aqueous solutions for a long time. Ultrasmall polyethyleneimine (PEI)-capped AuNPs (PEI-AuNPs) with limited agglomeration were prepared in aqueous solutions at room temperature, which were based on the roles of PEI as a reductant and a stabilizer. PEI-AuNPs with an average size of 8~12 nm formed highly stable nanocolloids with an average hydrodynamic cluster size of around 50 nm in aqueous media. At a low concentration of metal precursor hydrogen tetrachloroaurate (III), the particle size was reduced noticeably. The typical peaks of gold were observed in the X-ray diffraction pattern of AuNPs. The cell viability of 98% was obtained in the case of PEI-AuNPs, while PEI was cytotoxic. The PEI-AuNP is considered to be a potential candidate as a contrast agent for computed tomography.

  • This study was conducted to identify relationships between lung function disorders and Metabolic Syndrome(MetS) that have common comorbidities such as Cardio Vascular Diseases(CVD). According to the hypothesis that there may be a significant relationship between them, analyses were conducted to identify the proper management point for those diseases. Overall, 53,829 data were taken from KNHANES 2008-2013. Included data were PFT(Pulmonary Function Test) done and age over 40. All the 14 confounders applied, only 8,137 cases (M:3,951, F:4,186) were left. Low pulmonary function was divided into two categories, obstructive and restrictive patterns, based on the Global Initiative for Chronic Obstructive Lung Disease(GOLD) criteria, while MetS was defined based on the revised NCEP-ATPIII criteria. The relationships between those diseases were analyzed using logistic regression analysis. In addition, for the prevalence rate, cross-tab analysis were conducted. There were no significant relationships observed between obstructive lung disease and MetS, but a restrictive pattern had a meaningful relationship with MetS. Specifically, MetS showed a higher prevalence rate for both obstructive and restrictive pattern patients than the control group. Restrictive pattern patients showed a higher prevalence rate to MetS than obstructive patients. Overall, restrictive lung patterns showed a meaningful association with MetS, but not with obstructive patterns. Additionally, the prevalence rate of MetS among restrictive patients was higher than among obstructive patients.

  • Ornaments are accessories for the decoration of the body or dress. They aren't unavoidably required one, but serve to make one's dress perfect as decorative industrial art objects. In Morocco, ornaments were initially used as a sign of social position or the class or an incantatory symbol. In effect, they were originally employed to adjust one's dress, not just for decoration, and they were of use for household economy. Gold, silver and handcraft available for exchange were a means of increasing one's property and an indication of social standing and wealth. In particular, the dress and jewelry of a bride was a measure of her family's wealth, regarded as a symbol of her chastity and value. The ornaments symbolically back up people's faith in supernatural power, and their real value is based on implicit form or way of decoration, not the external shape. Specifically, there is a tendency to use the form of animal as a protector, not one to frighten people. In the artistic tradition of Morocco, fish pattern stands for water and rain, and eagle and bird are considered to be related to fate. Scorpion and lizard are depicted as an inquirer of sun, and snake is a symbol of abundance and sexual instinct, being viewed to have an ability to cure disease. Turtle pattern is a symbol of saint because it protects one from the evil. The ornaments are made of gold, silver, amber, clam, garnet, glass, nielle, enamel, glaze, coral or tree, and symbolic patterns are used, including hand(a symbol of five numerals), turtle, lizard, scorpion, eye, triangle, bird and eggs. They are very big and diverse, being categorized into ornaments for the head or the chest, neckless, fibula, earring, bracelet and ring. For Moroccans, make-up is a sort of instinctive behavior to meet aesthetic and sexual desire. They also wear make-up for practical purpose of protection, intentionally inflict a wound on the skin for ceremonial or religious purpose, paint the skin with pigment, or have the part of the body tattooed for incantatory purpose. All this actions are regarded as make-up. The raw material of cosmetics is aker, a vegetable dye. They get the lips or cheeks turn red and paint eyebrows with yellow saffran powder to have a bad devil lose its strength. Tattooing is mainly done by women and viewed as a sign of their value or social organization they belong to. Sometimes that is used to represent a woman's being old enough to marry or getting married already or the frequency of marriage. Besides, tattoo is believed to prevent or remedy loose bowels or cough, depending on its location or pattern, and they often change tattoo according to the change of beauty art.

  • In order to observe the localization of excretory, purified and infected antigenic protein in the tissue of Trichinella spiralis larvae, immunogoldlabeling methodology using IgG and protein A-gold complex was implemented. T. spiralis larvae obtained from rat muscle were initially cultured in medium, and secreted excretory antigen was collected for 1 or 3 days. Purified antigenic protein was obtained from homogenized T. spiralis larvae. Rabbits were then immunized with 1 or 3 days secreted excretory protein and purified 45 kDa protein, and IgG was purified from collected serum. Serum, against infected antigen, collected from rat on 1 and 4 weeks after infection with T. spiralis larvae, and IgG was purified from collected serum. T. spiralis larvae were embedded in Lowicryl HM20 medium. Then they were finally treated with immunized IgG and protein A-gold complex (particle size; 15 nm) and observed under electron microscope. In T. spiralis larvae tissue, the tissue antigen reacted with rabbit IgC antigen Day 1 secreted excretory protein, infected antigenic protein and purified 45 kDa protein. But different distribution pattern of labeled gold particles were observed. When Day 1 secreted excretoy protein was used, gold particle labeling was observed specifically on the cuticle, basal layer, esophagus interstitial matrix (EIM) and ${\alpha}_0,\;{\alpha}_1$ granules of stichocyte of the worm. In a separate group of tissue, the antigen reacted with rabbit IgG against Day 3 secreted excretory protein. Labeled gold particles were specifically distributed on the surface layer of cuticle, EIM and ${\alpha}_0$ granules of stichocyte of the worm. In case of using infected antigenic protein, gold particle labeling was specifically distributed on the cuticle and EIM of the worm. When purifed 45 kDa protein was used gold particle labeling was specifically distributed on the cuticle, basal layer, EIM and ${\alpha}_0,\;{\alpha}_1$ granules of stichocyte of the worm. Therefore, excretory antigens appeared to originate from the cuticle and ${\alpha}_0,\;{\alpha}_1$ granules of stichocyte for the first day but the cuticle layer associated with globular proteins and ${\alpha}_0$ granules of stichocyte after 3 days and infected antigens appeared to originate from the cuticle for 1 and 4 weeks after infection. These results suggest that excretory and infection specific antigens are secreted into the cuticle, basal layer, EIM and ${\alpha}_0,\;{\alpha}_1$ granules of stichocyte and 45 kDa protein may be contained these specific antigens.

  • Background: It is unclear as to whether the size ratio elastographic technique is useful for assessing ultrasound-detected ductal carcinoma-in-situ (DCIS) masses since they commonly lack a significant desmoplastic reaction. The objectives of this study were to determine the accuracy of this elastographic technique in DCIS and examine if there was any histopathological correlation with the grey-scale strain patterns. Materials and Methods: Female patients referred to the radiology department for image-guided breast biopsy were prospectively evaluated by ultrasound elastography prior to biopsy. Histological diagnosis was the gold standard. An elastographic size ratio of more than 1.1 was considered malignant. Elastographic strain patterns were assessed for correlation with the DCIS histological architectural patterns and nuclear grade. Results: There were 30 DCIS cases. Elastographic sensitivity for detection of malignancy was 86.7% (26/30). 10/30 (33.3%) DCIS masses demonstrated predominantly white elastographic strain patterns while 20/30 (66.7%) were predominantly black. There were 3 (10.0%) DCIS masses that showed had a co-existent bull's-eye sign and 7 (23.3%) other masses had a co-existent toothpaste sign, a strain pattern that has never been reported in the literature. Four out of 4/5 comedo DCIS showed a predominantly white strain pattern (p=0.031) while 6/7 cases with the toothpaste sign were papillary DCIS (p=0.031). There was no relationship between the strain pattern and the DCIS nuclear grade. Conclusions: The size ratio elastographic technique was found to be very sensitive for ultrasound-detected DCIS masses. While the elastographic grey-scale strain pattern should not be used for diagnostic purposes, it correlated well with the DCIS architecture.

  • In general, alkanethiolates having carboxylic acid in the tail group have been used as biorecepton. In this study, we have immobilized a cytochrome c protein using conjugated aromaticthiolates in order to improve the electrical property and physical stability of alkanethilolates. The pattern formation of self-assembled aromaticthiolate monolayers was as follow. Aromatic thiolates bound on the gold surface by the adsorption of 4'-mercapto-biphenyl-4-carboxylic acid and 4-mercapto-[1,1';4',1']terphenyl-4'-carboxylic acid were oxidized by the irradiation of deep UV light through a negative mask. The negative type pattern of the self-assembled monolayer (SAM) was obtained by developing with a deionized water. The pattern formation and electrical conductivity of aromaticthiolate SAMs was investigated by the measurements of STM and AFM. In addition, cytochrome c or ferrocene amide was immobilized onto the patterned substrate. We also studied on the effect of conjugated aromatic thiolates on the electrical activity of cytochrome c or ferrocene amide by cyclic voltammetry.

  • The Gollyongpo was worn by the King and the Crown Prince in Joseon dynasty as an ordinary wear. The research on the Gollyongpo is focused on the historic record of Joseon dynasty, Joseonwangjosillok. This study will analyze literature, paintings and relics. First, I have researched Ming's(China) representative document daminghuidian, and excavated relics from the tomb dingling. I examined the usage and characteristic, through various remaining literature data, artifacts and paintings. The Gollyongpo was worn for the various ceremonies as well as an ordinary wear. According to the periode, the style and color had changed. The King wore the red Gollyongpo with 5 clawed dragon pattern, the Crown Prince wore black one with 4 clawed pattern, and the eldest son of the Crown Prince wore black one with 3 clawed dragon emblem. After the Daehan Empire, the Emperor wore gold outfit and the Crown Prince wore red outfit. Sonyongpo recorded in the Gungjungbalgi is concerned as Gollyongpo with narrow straight sleeve, one of the Sejong University Museum's Collection. There is some Possibility that the Gollyongpo painted in Bongsado is woven with dragon design, I would leave this matter for next research task.

  • The purpose of this study is to analyze the aesthetic characteristics of traditional Korean patterns appearing on fashion collections from 1990 to 2005. Traditional Korean patterns have been used as an important element to express a Korean image since the 1990s. Frequently used patterns included several kinds of geometric patterns, plant patterns(flower, peony, Four Gracious Plants), and Chinese character patterns. Specifically, since the 2000s, animal patterns such as tiger, Chinese phoenix, and giraffe which were not often used, plant patterns such as arabesque, peony, and flower, and a variety of Chinese character patterns appeared. For the expression techniques, while embroidery and printing was often used in the 1990s, they became varied into printing, beading, embroidery, gold and silver leaf, and hand painting after 2000 as a result of designers' active attempts. The aesthetic characteristics of fashion design with its focus on traditional patterns were analyzed. First, Chinese character patterns and phoenix pattern which were mainly used for a court suit, and show the excellence and unique originality of Korean culture. Second, traditional Korean patterns directly and indirectly imply symbolistic significance of lucky sign and illustrate the use of various lucky sign patterns. Third, traditional Korean patterns such as arabesque or peony were expressed by colorful embroidery to add decorative beauty. Finally, traditional Korean patterns reflect a naturalistic worldview and are completed finished as the design.

  • Reduction mammaplasty is the gold standard treatment for gigantomastia. We report one female patient with juvenile gigantomastia associated with severe pulmonary hypertension where her pulmonary pressure decreased significantly after the surgery, improving her quality of life. A 22-year-old female patient with gigantomastia since 10 years old, tricuspid regurgitation, and pulmonary thromboembolism antecedent was admitted to the emergency department. Her oxygen saturation was 89%. Acute heart failure management was initiated. An echocardiogram reported left ventricle ejection fraction (LVEF) of 70% with severe right heart dilation, contractile dysfunction, and arterial pulmonary pressure (PASP) of 110 mm Hg. A multidisciplinary team considered gigantomastia could generate a restrictive pattern, so a Thorek reduction mammoplasty with Wise pattern was performed. Presurgical measurements were: sternal notch to nipple-areola complex, right 59 cm, left 56 cm. Three days after surgery, the patient could breathe without oxygen support. In the outpatient follow-up, patient referred reduction of her respiratory symptoms and marked improvement in her quality of life. Six months after surgery, a control echocardiogram showed a LVEF of 62% and PASP of 85 mm Hg. Pulmonary hypertension may be present in patients with gigantomastia. Reduction mammoplasty may be a feasible alternative to improve the cardiac signs and symptoms in patients with medical refractory management.
