In the tide of globalization, culture products play pivotal role in effectively introducing our tradition and culture to the world. This research is about developing culture products using our traditional lady's art craft work to attain the purpose of modern application through recreation of tradition along with modern technology. First, the types of traditional lady's art craft work include pouches, wrapping clothes and other accessories made by sewing except costumes. The materials used were cotton, silk, ramie, hemp and decorating techniques involved were embroidery, patchwork, quilting, knot. Second, the purpose of this study is developing culture products with traditional images which also satisfy modern sense. Therefore, items that could be used readily in daily life were selected. Such items include bags, mufflers, name card cases, brooches. In addition, the Korean traditional Patchwork images which have both western-style and modern sense were selected out of the many kinds of traditional lady's art craft works. Third, cultural products (bags, mufflers, name card cases, brooches) were created by DTP in silk with sacdong and free-styled division Korean traditional Patchwork images and quilting technique. The significance of this study lies in examining the possibility of developing modern culture products using traditional lady's art craft work. A way to further develop this study would be to shed new light on traditional crafts and local cultural resources and actively carry on the study of cultural product development to provide the foundation for developing cultural products with modern applications.

This study provides a detailed morphological description of larvae obtained from Urocampus nanus and Syngnathus schlegeli male brood fish over 20 days of culture in the laboratory. In both species, mating takes place when several males each spread their brood pouch like a wing to attract a female's attention. When the female begins to swim upward, the males follow her and receive her eggs in their brood pouches. Newborn larvae of U. nanus and S. schlegeli had already completed formation of dorsal and caudal fin rays, but not of pectoral fin rays. Pectoral fin rays were completely formed 15 days after release in S. schlegeli and 20 days after release in U. nanus. The ratio of caudal fin length to standard length increased until 8 days and decreased thereafter in S. schlegeli, while in U. nanus this ratio declined continuously after hatching. The larvae of the two species were very similar in external morphology, but well distinguished by the number of dorsal fin rays (15-16 in U. nanus vs. 39-43 in S. schlegeli), the presence of a membrane under the tail (absent in U. nanus vs. present in S. schlegeli), and the presence of melanophores in the dorsal fin (present in U. nanus vs. absent in S. schlegeli). Based on this study, U. nanus appears to be evolutionally more similar to pipefish than to seahorse.

DiGeorge syndrome is an immunodeficient disease associated with abnormal development of 3rd and 4th pharyngeal pouches. As a hemizygous deletion of chromosome 22q11.2 occurs, various clinical phenotypes are shown with a broad spectrum. Conotruncal cardiac anomalies, hypoplastic thymus, and hypocalcemia are the classic triad of DiGeorge syndrome. As this syndrome is characterized by hypoplastic or aplastic thymus, there are missing thymic shadow on their plain chest x-ray. Immunodeficient patients are traditionally known to be at an increased risk for malignancy, especially lymphoma. We experienced a 7-year-old DiGeorge syndrome patient with mediastinal mass shadow on her plain chest x-ray. She visited Severance Children's Hospital hospital with recurrent pneumonia, and throughout her repeated chest x-ray, there was a mass like shadow on anterior mediastinal area. We did full evaluation including chest computed tomography, chest ultrasonography, and chest magnetic resonance imaging. To rule out malignancy, video assisted thoracoscopic surgery was done. Final diagnosis of the mass which was thought to be malignancy, was lymphoproliferative lesion.

This study was designed to investigate the stability for chemical contents and biological activities of Mahwang-tang (MT) depending on the preservation temperature and periods. MT decoction pouches were preserved for 3 months at room temperature (RT, $23{\pm}1^{\circ}C$) and refrigeration ($4^{\circ}C$). To evaluate the stability of MT decoction, pH and sugar content were estimated. High-performance liquid chromatography analysis were performed to quantify the contents of marker compounds in MT. Anti-inflammatory effects of MT were evaluated to suppress the generation of nitric oxide, prostaglandin $E_2$ and cytokines (tumor necrosis $factor-{\alpha}$ and interleukin-6) in the RAW 264.7 cells stimulated with lipopolysaccharide. Total antioxidant capacity of MT was determined by ABTS radical scavenging activity. The pH of storage method and period showed a tendency to decrease gradually with time. There were no changes in sugar content depending on the preservation temperature and periods of MT decoction. Among the major components of MT, cinnamaldehyde was reduced time-dependently for 3 months of storage at RT. The inflammatory effect and antioxidant capacity of MT were reduced time-dependently at both RT and $4^{\circ}C$. Our results suggest that the preservation period of MT decoction is recommended in refrigeration within 3 months or less rather than at RT.

Purpose: Human tooth proteins are highly heterogeneous, comprising diverse proteins derived from a number of genes. The attempts to identify protein for activity of tooth matrix proteins have been defied by several factors. First, the amount of proteins within teeth is very small relative to many extracellular matrix proteins of other tissues. Second, the bioassay system is tedious and needed for long time. Therefore we tried to find easy techniques, which increase the product rate, and an assay of small proteins, with which amino acid sequence is possible without additional procedures. Materials and Methods: Total protein were extracted from 300 g enamel removed teeth and 600 g teeth with 4 mol/L guanidine HCl and purified by gel chromatography. Aliquot of proteins was implanted into muscle pouches in Sprague-Dawley rats for bioassay. By SDS-PAGE and membrane blotting, molecular weight of each protein was estimated and a partial amino acid sequence was obtained. Each fraction blotted on the membrane was cut out and inserted in rat ectopic model. Results: In dissociative method, total tooth proteins were obtained 1mg/ml from enamel removed teeth and 3.5 mg/ml from teeth. In SDS-PAGE, four clear bands at the sites corresponding to 66, 40, 20 and 18 kD. Especially The 66 kD band was clearly exhibited. Amino acid sequencing from tooth could be possible using PVDF membrane blotting technique. In amino acid sequencing, 66 kD protein was identified as albumin. Conclusion: Compared with conventional method for extraction of teeth protein and bioassay of proteins, the methods in this study were easy, time-saving and more productive technique. The matured tooth proteins omitting additional procedure of mechanical removal of enamel were simply analyzed using blotted PVDF membrane. This method seems to make a contribution as a technique for bioassay and amino acid sequencing of protein.

Traditional culture could be a wonderful source of inspiration for creative design. Tteoksal, the stamps used for making decorative patterns on traditional rice-cakes, have been used and passed on to generations to show the emotions of our ancestors. Numerous traditional patterns found in Tteoksal can be used to better understand and transmit tradition in modern ways. The purpose of this study was to develop fashion cultural products with a modern sensibility by understanding the origin, types and characteristics of Tteoksal and its patterns. The method of this study was through considering the proceeding studies and the references published by a specialist and museums having some information about further knowledge on Tteoksal. In line with the aforementioned study, neckties, eco-friendly bags and pouches were developed as fashion goods. Among the Tteoksal's patterns selected were lotus, bats, 樂 letters and complex patterns. Using a computer graphic software program such as Adobe Illustrator CS5, archetypes of patterns were traced as vector graphics, and two design motives were developed in every pattern. The patterns were developed into two types: one was a basic pattern faithful to a basic motive pattern, and the other was a varied type that was changed and applied. The fashion products were developed as two styles for basic and varied patterns for neckties, eco-friendly bags and pouch items. Twelve products were made for each pattern, which totals 48 unique products. In conclusion, the study could be a critical step to better understand the traditional culture and its influence to the patterns applied to modern fashion design.

This study was designed to determine the most suitable manufacturing conditions of stewed pumpkin juice(SPJ) in terms of nutrition and taste. Well ripened pumpkin was heated for 3, 4, 5, 6 and 7 hours in a pressure cooker and then extracted and packed in retort pouches. These were kept at 4$^{\circ}C$ and 28$^{\circ}C$ for 30 days, respectively and changes of the physicochemical components of SPJ were investigated. The free amino acid compositions of pumpkin and SPJ occupied asparagine, aspartic acid, glutamine, arginine and serine in increasing order of abundance. Except SPJ heated for 3 hours, SPJ stored at 28$^{\circ}C$ had the most abundant free amino acids, followed by SPJ stored at 4$^{\circ}C$, and SPJ not stored. The fatty acid composition of pumpkin occupied behenic acid, erucic acid, palmitic acid, linoleic acid, heneicosanoic aicd, in order of abundance. When SPJ was heated over 3 hours, palmitic acid and linolenic acid decreased greatly. SPJ stored at 4$^{\circ}C$ and 28$^{\circ}C$ increased contents of saturated fatty acids such as behenic acid, palmitic acid than SPJ not stored. As SPJ was heated for a long time, carotenoid was mostly destroyed and the Hunter "L", "a" and "b" values of SPJ decreased. Among the mineral constituents of SPJ, Na and Ca were dominantly occupied. It was found that the range of the total visible cell count was 3~4CFU/ml from the SPJ which was heated for 3 hours and it increased by 1$\times$109CFU/ml when the SPJ was stored at 28$^{\circ}C$. It seems that the contamination by microorganism have occurred at packing process. In sensory evaluation, the SPJ which was heated for 5 hours had the highest scores in overall preference, sweet smell and sweetness.ce, sweet smell and sweetness.

Prescription filling in powder form is performed in community pharmacy practice to adjust dose for children and patients who cannot swallow whole tablet. However, there are few reports regarding the stability of the active ingredient and possible microbial growth after the medication is dispensed to powder form. This study examined the stability of atenolol, an antihypertensive agent, and microbial growth in the unit dose pouches dispensed at twenty-one community pharmacies located in Taegu area. Randomly chosen first unit dose pouch contained 77.4% of the prescribed dose of the drug and there were only four community pharmacies that dispensed the drug within 10% deviation from the dose prescribed by physician. Surprisingly, there were three community pharmacies that dispensed the drug with greater than 40% deviation, which may pose a major concern regarding the efficacy and safety of the drug prescribed for the treatment of hypertension. Atenolol content during a month did not indicate significant change, showing 5.4%, 4.3%, and 3.3% of decrease in 50%, 80%, and 90% relative humidity conditions, respectively. Microbiological examination during a month showed less than 0.5 microorganism in high power field (hpf) in all the relative humidity conditions tested. Based on this study, pharmacy practice in community pharmacy needs to be rigorously regulated to ensure that the dose of the prescribed drug is properly incorporated into the unit dose pouch dispensed as powder form.

Purpose: The purpose of this study was to determine the most appropriate shelf life for sterilized products according to their packaging material. Methods: Samples were prepared to target six nursing units in one general hospital in Seoul. After steam and E.O gas sterilization, sterilized product, samples were supplied to wards. Data collection was conducted for 3 months, after the expiration date of 3 months had passed for samples packaged with crepe paper and nonwoven wraps. For samples packaged with paper-plastic pouches, data collection conducted for 3 months when the expiration date of 9 months had passed. The sterilized products were collected and tested for microbial contamination. Identification of the storage environment was done as samples were collected. Results: This study confirmed that the storage environment met international standards such as CDC, except for temperature. For steam sterilized crepe paper packaging samples and steam and E.O gas sterilized for nonwoven packaging samples no contamination in all products was found for 3 months past the expiration date. However, in the E.O gas sterilized paper-plastic pouch packaging sterile samples, Gram-positive bacilli were detected in one sample from a surgical intensive care unit at 45 weeks and another sample from an operating room at 47 weeks. Furthermore, the results did not show any microorganisms for up to 52 weeks in all products. Conclusion: According to the results of this study, sterilized product packaging made with crepe paper and nonwoven wraps is better able an extended shelf life from 3 months to 6 months, reducing unnecessary costs.
