This article is written on the ground that one of the major characteristics of Chinese New Period women's novels is about family dissolution and calling and it is examined based on analysis of "The Bathing Woman" by Tie Ning. In "The Bathing Woman", the family seems 'Regular' externally but it is actually fragmented internally. The author offers patriarchal perspective on 'Family' from the eyes of daughter of the family. The problems are classified into three categories. First, it is the problem of exclusiveness embedded in the essential characteristic of family represented by blood relation. Second, it is the research on the reason for family dissolution. Tie Ning finds the reason at 'Unmotherly mother, that is the lack of maternal instinct. Third, it is the expectation of the restoration of dissolved family. Tie Ning's indication of 'Family' is equal to 'Mother' and 'Mother' is the source and power that can heal and restore the dissolved family in her novel. It is expansion of maternal instinct represented by protection and caring into 'Practical action' and it is meaningful in a way that it expands the principle of maternal instinct and sublimates it into universal morality. However, it should not be overlooked that it could be another moral system that could suppress the females in other ways.

This research improved the growth potential of Bifidobacterium animalis subsp lactis strain JNU306, a commercial medium that is appropriate for large-scale production, in yeast extract, soy peptone, glucose, L-cysteine, and ferrous sulfate. Response surface methodology (RSM) was used to optimize the components of this medium, using a central composite design and subsequent analyses. A second-order polynomial regression model, which was fitted to the data at first, significantly lacked fitness. Thus, through further analyses, the model with linear and quadratic terms plus two-way, three-way, and four-way interactions was selected as the final model. Through this model, the optimized medium composition was found as 2.8791% yeast extract, 2.8030% peptone soy, 0.6196% glucose, 0.2823% L-cysteine, and 0.0055% ferrous sulfate, w/v. This optimized medium ensured that the maximum biomass was no lower than the biomass from the commonly used blood-liver (BL) medium. The application of RSM improved the biomass production of this strain in a more cost-effective way by creating an optimum medium. This result shows that B. animalis subsp lactis JNU306 may be used as a commercial starter culture in manufacturing probiotics, including dairy products.

The objective of this study was to fabricate a novel hydrophobic stent for reducing restenosis by employing electron beam equipment. The stent was fabricated from a CoCr alloy tube by using a femtosecond laser and was treated with argon plasma. Subsequently, the stent's surface specification changed from hydrophilic to hydrophobic. Application of the electron beam offers several advantages such as a short processing time, whole surface reforming, and enhancement of material properties. As the surface of the stent was rendered hydrophobic, it can provide equivalent or enhanced mechanical properties and greater functionality with a higher radial force at the extended stent in a blood vessel. The obtained results corresponding to the mechanical properties indicate that the contact angle increased to approximately 130°, and the radial force increased to approximately 3 N. Furthermore, cell culture experiments were conducted for verifying whether cells were cultured on the surface-modified CoCr surface. Based on the obtained results, it is believed that an effective reduction in the restenosis of inserted vascular stents is possible.

One of the most common sources of spinal pain syndromes is the facet joints. Cervical, thoracic, and lumbar facet joint pain syndromes comprise 55%, 42%, and 31% of chronic spinal pain syndromes, respectively. Common facet joint disorders are degenerative disorders, such as osteoarthritis, hypertrophied superior articular process, and facet joint cysts; septic arthritis; systemic and metabolic disorders, such as ankylosing spondylitis or gout; and traumatic dislocations. The facet pain syndrome from osteoarthritis is suspected from a patient's history (referred pain pattern) and physical examination (tenderness). Other facet joint disorders may cause radicular pain if mass effect from a facet joint cyst, hypertrophied superior articular process, or tumors compress the dorsal root ganglion. However, a high degree of morphological change does not always provoke pain. The superiority of innervating nerve block or direct joint injection for diagnosis and treatment is still a controversy. Treatment includes facet joint injection in facet joint osteoarthritis or whiplash injury provoking referred pain or decompression in mass effect in cases of hypertrophied superior articular process or facet joint cyst eliciting radicular pain. In addition, septic arthritis is treated using a proper antibiotic, based on infected tissue or blood culture. This review describes the diagnosis and treatment of common facet joint disorders.

Superior vena cava(SVC) syndrome is mostly related to a malignant process, but many different benign causes have also been described. We report a case of SVC syndrome caused by Klebsiella pneumonia diagnosed by sputum culture and serial chest X-ray changes. A 27-year-old man had been in stable health until three days before admission, when he complained of pleuritic chest pain, facial flushing, and shortness of breath. Examination of the head and neck disclosed edema of face and both arms, and jugular venous distention to the angle of the jaw. The chest auscultation revealed decreased breath sound without crack1e on right upper lung field. The chest roentgenogram showed homogenous air space consolidation on right upper lobe, asociated with downward displacement of minor fissure and contralateral displacement of trachea, but air bronchogram was not seen. We began antibiotic therapy under impression of pneumonia after available culture was taken from blood and sputum. SVC scintigraphy showed stasis of drain of right brachiocephalic vein at the proximal portion with reflux into the right internal jugular vein and faintly visible SVC via the collaterals. Sputum culture revealed Klebsiella pneumoniae. Antibiotic therapy resulted in a cure of infection and disappearance of facial swelling. Follow-up SVC scintigraphy after 20 days showed normal finding. We first report a case of SVC syndrome caused by klebsiella pneunonia.

The growth patterns of primary culture of bovine brain microvessel endothelial cells (BBMECs) were studied using electron microscopy when grown on $3.0{\mu}m$ and $0.4{\mu}m$ pore Transwell. The capillary fragments and isolated endothelial cells grew on collagen coated culture plate and Transwell membrane. The BBMECs grew only on the upper surface of membrane of $0.4{\mu}m$. But BBMECs on $3.0{\mu}m$ pore membrane migrated through the pore and grew on the opposite side of the membrane. In summary, BBMECs isolated by enzyme digestion could migrate through $3.0{\mu}m$ pore membrane but not through $0.4{\mu}m$ pore membrane. So $0.4{\mu}m$ pore membrane instead of $3{\mu}m$ pore membrane should be used for drug transport experiment or transendothelial electrical resistance measurement.

For reconstruction of the bony defect, various artificial substitutes were developed. Among them, there has been a study of calcium phosphate coated bone substitutes for increasing attachment of osteoblasts in vivo. The purpose of this study was to evaluate the effects of serum and platelet-rich plasma (PRP) on calcium phosphate coated culture plate for the initial attachment, proliferation and activity of osteoblasts. After sampling the blood from white rats and concentrating by centrifugation, the amount of attachment of PDGF-BB and $TGF-{\beta}$ on the calcium phosphate coated culture plate was measured. Cultured HOS and ROS 17/2.8 cell was measured on attachment level and proliferation rate of osteoblasts. Alkaline phosphatase activity of HOS and ROS 17/2.8 cell was measured for studying on the activating rate of osteoblast. 1. Counting the amount of platelets of seperated plasma and PRP, the average number of platelets was 177,003 $cell/{\mu}l$ in plasma, and 1,656,062 $cell/{\mu}l$ in PRP, which was about 9 times as high as in plasma. 2. Amount of PDGF-BB deposited at calcium phosphate coated plate had increased by the total amount of plasma and PRP on the culture plate, whereas $TGF-{\beta}$had been deposited on the plate only when treated by $50{\mu}{\ell}$ of PRP(p<0.01). 3. After plating serum and PRP for 3 hours, we attached with HOS and ROS17/2.8 cell for 1 hour and 4 hours. There were no significant difference of the attachment between serum and control group, whereas there were significantly difference of the attachment between depositioning of PRP and control group. 4. After attaching plasma and PRP for 3 hours, cell number has much increased when HOS and ROS17/2.8 cell had been cultured for 48 hours(p<0.05). 5. After attaching plasma and PRP for 3 hours, concentration of alkaline-phosphatase has increased when HOS and ROS17/2.8 cell had been cultured for 48 hours(p<0.01). These results suggested that PRP affected on initial cell attachment rather than proliferation and activation of osteoblasts at calcium phosphate coated plate.

In vitro IgE class switching could be induced through co-culture of CD40L-expressing KU812 cells and CD40-expressing B cells in the presence of IL-4 or IL-13. It has been generated several B cell lines, which produce rice allergen (RA)-specific IgM antibody by in witγo immunization (IVI) using peripheral blood lymphocyte (PBL). In this study, induction of RA-specific IgE antibody by KU812 cells was attempted. Before co-culture, we determined the CD40 expression in RA-specific B cell lines, RA9G11 and the CD40 ligand (CD40L) expression in activated KU812 cells by treatments with phorbol myristate acetate (PMA) and ionomycin for 6 hrs. Flow cytometric analysis shown that RA9G11 and activated KU812 cells expressed high level of CD40 and CD40L, respectively. RA9G11 cells were cultured with activated KU812 cells for 12 days in the presence of IL-4 for IgE class switching. Mature $C{\varepsilon}$ mRNA level and RA-specific IgE spot forming cells (SFC) were observed in all culture condition, and especially, high level of RA-specific IgE synthesis was determined the same ratio of RA9G11 and activated KU812 cells in the presence of 50U IL-4. Therefore, induction of RA-specific IgE synthesis by activated KU812 cells can be contributed in the application for allergic therapy and prevention.

The present study investigated Bul-Chun-Wi Sacrificial Ritual (sacrificial service which has been handed down from generation to generation to worship the family ancestors in the period of $1400{\sim}1800$) and foods for the sacrificial service among fourteen head families in Andong area. The findings are as follows; 1. In Bul-Chun-Wi Sacrificial Rituals, family shrine has been maintained in good shape, and the table, dishes, and foods used in the rituals have not been changed so much until these days. 2. While vegetable soup is widely used as soup, one family uses the seaweed soup, the other soup mixed with meat, fish, and vegetable. Specially soybean-powdered soup, which is the distinguishable food in Andong area, has been used. 3. As a basic Ddock, mainly Si-Ru-Ddock(a steamed rice cake), piled up to 13-15 stacks, is used. Additional 7-9 kinds of Ddock are placed on top of the basic Ddock. 4. For grilled-meat food(Geuck), eight families use the raw meat, and one family uses the half-cooked meat. Recently, five families have used the cooked meat. Mostly used ones are meat-Geuck, fish-Geuck, chicken-Geuck, and the Geuck are not served one by one. Instead the Geuck are stacked in one dish designed for Geuck in order of meats from poultry, animal, fish, and shell. As the sub-dishes for rice, raw and cooked Geuck are used. 5. The number of stew (Tang) are 3 to 6 and 5 stews is the most popular. Commonly used stews are meat stew, fish stew, chicken stew, vegetable stew, blood stew, and organs stew. For the vegetable stew, buckwheat gel can be used. 6. As the fruit, chinese date, pear, nut and dried persimmons are the basic ones. The even number of 6 or 8 colorful fruits are used, while the odd number of 7 or 9 colorful fruits are used in three head families. 7. As Sik-Hae which is a drink and made from fermented rice, rice Sik-Hae or fish Sik-Hae has been necessarily used. 8. As raw meat dish, the liver of cow or meat is used. As a wrapping materials, the reticulum of a ruminant, green seaweed or thinly fried egg can be used.
