The purpose of this study was to present the plan for activation and rationalization of production of ladies' jacket and provide basic materials for improvement of the development of technologies in relation to the productivity improvement of ladies' jacket and the achievement of high quality product. For this purpose, this study attempted to investigate the present situation of jacket manufacturing process. The data is related with local ladies' jacket manufacturing companies in Seoul snd Kyonggi area. The results of this study are as follows. 1. 87.8% of the business firms responded that they acquired the productive process of jacket based on their own knowhow and 80.5% was aware of the need for the analysis of each process. The highest proportion of the business firms(65.9%) pointed out that the advantage of process analysis was the alleviation of the production time. 2. The jacket manufacturing process was made up of 4 stages such as the process of frontal/rear plate $\rightarrow$ the process of accessories $\rightarrow$ the process of completion $\rightarrow$ the process of finishing in a broad sense but composed of a total of 19 stages in detail. 3. Attachment of the sleeves(73.2), attachment of the collar(41.5%) and the formation of the overall silhouette(22.0%) were raised as the challenge in manufacturing ladies' jacket. 4. Most of the sewing business firms made use of the method of completing the collar and then stitching the outer material and the inner collar, and the line of the bodice and the outer collar as the method of stitching the tailored collar. and many of them used the method of completing the collar and then inserting it between the line of the bodice and the outer material and stitching it as the method of stitching the stand collar. They had a preference for the method of completing the sleeve and connecting it to the bodice as the method of stitching the sleeve. and used the method of treating the margin to seam of semi-lined and unlined jacket by treating it with the bias tape.

Calcium carbonate(CC) is biocompatible and gradually absorb to be replaced by bone when implanted into bone tissue. Fibrin-fibronectin sealant system (FFSS) is a product of human-derived plasma. The effect is hemostasis, tissue fixation and adhesion, We expect synergic effects of this two materials in periodontal regeneration. When FFSS was grafted with bone graft in intrabony defects, could be eliminated exofolication of bone graft materials. This study evaluated above materials for periodontal regeneration of 6mm intrabony defects in 36 patients. lap surgery was carried in 14 defects of control group. experimental group 1 was 11 defects grafted with calcium carbonate, experimental group 2 was 11 defects which were grafted with calcium carbonate with FFSS. The clinical parameters evaluated included changes in attachment level, probing depth, gingival recession at 6 months. Postsurgery probing depth reduction was 3.1 ${\pm}$ 0.9mm in control, 3.8 ${\pm}$ 1.6mm in experimental group 1, 4.1 ${\pm}$ 1.1mm in experimental group 2. The result clinically and statistically improved compared to baseline(P<0.01), but the difference found among the groups were not statistically significant. Postsurgery clinical attachment level was 1.6 ${\pm}$ 1.2mm in control, 3.5 ${\pm}$ 2.0mm in experimental group 1, 3.3 ${\pm}$ 1.2mm in experimental group 2. All of the control and experimental groups resulted in a statistically significant reduction from baseline(P<0.01). The reduction of the experimental groups were statistically significant from control(P<0.05). But the change between experimental group 1 and experimental group 2 was not statistically significant. We conclude that mixture of CC and FFSS is effective to periodontal regeneration in intrabony defect.

Objectives : We examined the use of the moxibustion through survey on Korean Medicine Doctors (KMDs) on preparation of universal moxa product standard by fully reflecting opinions of practitioners and the industry. Methods : The questionnaire is composed of 25 questions including use of indirect moxa, side effects, complaints and improvements, general characteristics and so on, and were responded by 1,588 KMDs. For statistics, frequency analysis, chi-square analysis, T-test and ANOVA were conducted using SPSS 12.0 for windows, and the significance level was 0.05. Results : In this research, 91% of the responded KMDs was using moxibustion, and the proportion of using mediate moxibustion was shown as 63.2%. They used mediate moxibustion for side effects of direct moxa method such as risk of burn, ease of use, control of stimulation and so on. And it was mostly being conducted to women and 40 ages. Most respondents gave moxibustion treatments for the purpose of thermal stimulation on acupoint to musculoskeletal diseases. Most respondents were treating 1~2 pieces of moxibustion to patients by moxibustion points to those of 1~2 regions every time within 10 minutes. Regarding the frequency of side effects of mediate moxibustion, within 3% of respondents had experienced side effects, and the types were burn, flare and itchiness, odor and smoke. The dissatisfaction of mediate moxibustion products was moderate(2.00 out of 5 point scale), and went up public health doctors, the younger ages and the shorter clinical experience. Complaints on mediate moxibustion products were serious odor, poor attachment, risk of burn etc. Regarding ways to improve mediate moxibustion, the expansion of moxibustion's insurance cost carne out highest, followed by preparation of manual on efficacy, strengthening of training, acquiring evidence on efficacy, diversification of specifications, safety improvement, quality improvement of mediate moxibustion products. Conclusions: Many KMDs use for ease of use and give moxibustion treatments for thermal stimulation but they complain about safety, efficacy and quality of mediate moxibustion. After this it is considered that we have to elevate therapeutic effect through the improvement of mediate moxibustion products.

Lactic acid bacteria (LAB) are widely used for various food fermentation. With the recent advances in modern biotechnology, a variety of bio-products with the high economic values have been produced using microorganisms. For molecular cloning and expression studies on the gene of interest, E. coli has been widely used mainly because vector systems are fully developed. Most plasmid vectors currently used for E, coli carry antibiotic-resistant markers. As it is generally believed that the antibiotic resistance markers are potentially transferred to other bacteria, application of the plasmid vectors carrying antibiotic resistance genes as selection markers should be avoided, especially for human consump-tion. By contrast, as LAB have some desirable traits such that the they are GRAS(generally recognized as safe), able to secrete gene products out of cell, and their low protease activities, they are regarded as an ideal organism for the genetic manipulation, including cloning and expression of homologous and heterologous genes. However, the vec-tor systems established for LAB are stil insufficient to over-produce gene products, stably, limiting the use of these organisms for industrial applications. For a past decade, the two popular plasmid vectors, pAM$\beta$1 of Streptococcus faecalis and pGK12 theB. subtilis-E. coli shuttle vector derived from pWV01 of Lactococcus lactis ssp. cremoris wg 2, were most widely used to construct efficient chimeric vectors to be stably maintained in many industrial strains of LAB. Currently, non-antibiotic markers such as nisin resistance($Nis^{r}$ ) are explored for selecting recombi-nant clone. In addition, a gene encoding S-layer protein, slp/A, on bacterial cell wall was successfully recombined with the proper LAB vectors LAB vectors for excretion of the heterologous gene product from LAB Many food-grade host vec-tor systems were successfully developed, which allowed stable integration of multiple plasmid copies in the vec-mosome of LAB. More recently, an integration vector system based on the site-specific integration apparatus of temperate lactococcal bacteriophage, containing the integrase gene(int) and phage attachment site(attP), was pub-lished. In conclusion, when various vector system, which are maintain stably and expressed strongly in LAB, are developed, lost of such food products as enzymes, pharmaceuticals, bioactive food ingredients for human consump-tion would be produced at a full scale in LAB.

Most work done in CSCW (Computer Supported Collaborative Work) system has been targeted toward supporting the exchange of documents or messages among group members, and yet support for cognitive aspects such as group organization, division and merge of work, and work flow control. The objective of the study is to provide CSCW environment for the engineering design process such as CAD (Computer Aided Design) and CASE (Computer Aided Software Engineering). The proposed DCWA (Distributed Collaborative Writing Aid) system suggests a mechanism that unifies the group organization, work division, and work flow control in the CAO, CASE, and software simulation tool. In particular, CAD relates the group and work partition by providing expressing the relation of drawing object (e.g., binding, attachment, and proportional scaling) which is owned by different members of group, and CASE combining with the simulation tool supports the flexibility of the work flow control. Simulating the prototype before manu-facturing a product can reduce time and cost in development.

Background: The effects of plant products on cancer cells has become a field of major importance. Many substancesmay induce apoptosis in anti-cancer treatment. Pectins, a family of complex polysaccharides, and their degradation products may for exasmple exert apoptotic effects in cancer cells. Apples and citrus fruits are the main sources of pectin which can be applied for anti-cancer research. The present study concerned an intact form of pectic-oligoshaccharide named pectic acid (poly galactronic acid). Materials and Methods: Inhibition of cell proliferation assays (MTT), light microscopy, fluorescence microscopy (acridin orange/ethidium bromide), DNA fragmentation tests, cell cycle analysis, annexin PI and Western blotting methods were applied to evaluate apoptosis. Results: The results indicated that pectic acid inhibited cell growth and reduced cell attachment after 24h incubation. This did not appear to be due to necrosis, since morphological features of apoptosis were detected with AO/EB staining and cell cycling was blocked in the sub-G1 phase. Annexin/PI and DNA fragmentation findings indicated that apoptosis frequency increased after 24h incubation with pectic acid. In addition, the data showed pectic acid induced caspase-dependent apoptosis. Conclusions: These data indicate that apple pectic acid without any modification could trigger apoptosis in MDA-MB-231 human breast cancer cells and has potential to improve cancer treatment as a natural product.

This study describes the retention of title under UCC. UCC ${\S}$ 2-401 prescribes that any retention or reservation by the seller of the title (property) in goods shipped or delivered to the buyer is limited in effect to a reservation of a security interest. It means that the retention of title generates a security interest in the same way like a charge. To be effective, a security interest must be attached or perfected. Once attachment occurs, a security interest is enforceable against the buyer. Once a security interest is perfected, a security interest is enforceable against third parties. Under UCC, a simple retention of title clause is valid as long as it is incorporated into the contract of sale. If the seller acquires a perfected security interest, he as a secured party can enjoy a priority against other creditors. But if a security interest is not perfected but PMSI is afforded, the seller has a special priority. Secondly, under UCC ${\S}$ 9-335 and 9-336, if a security interest under an enlarged retention of title clause is perfected, the seller as the secured party has a valid security interest in the product or mass into which his goods have been mixed or commingled. But in terms of assession of goods, as the seller has a security interest only in his goods, if the seller wants to enlarge his security interest in the whole, a security agreement should cover its intention. Thirdly, under UCC ${\S}$ 9-315, a security interest in proceeds of subsale of goods supplied by the seller is a perfected security interest if the security interest in the original collateral was perfected. But if the proceeds are cash proceeds, it should be identifiable from other funds of the buyer.

27-Hydroxycholesterol (27OHChol) has been reported to induce differentiation of monocytic cells into a mature dendritic cell phenotype. We examined the effect of methanol extract of Nardostachys chinensis (Nard) on 27OHChol-induced differentiation using THP-1, a human monocytic cell line. Treatment of monocytic cells with methanol extract of Nard resulted in decreased transcription and surface expression of CD80, CD83, and CD88 elevated by 27OHChol in a dose-dependent manner. Surface levels of MHC class I and II molecules elevated by 27OHChol were also reduced to basal levels by treatment with the Nard extract. Decreased endocytosis activity caused by 27OHChol was recovered by treatment with the Nard extract. CD197 expression and cell attachment were attenuated by the Nard extract. In addition, levels of transcription and surface expression of CD molecules involved in atherosclerosis, such as CD105, CD137, and CD166 upregulated by 27OHChol were significantly decreased by treatment with methanol extract of Nard. These results indicate that methanol extract of Nard down-regulates 27OHChol-induced differentiation of monocytic cells into a mature dendritic cell phenotype and expression of CD molecules associated with atherosclerosis. The current study suggests that biological activity of oxygenated cholesterol derivatives can be inhibited by herbal medication.

In the domestic cosmetics market, it is important to secure high customer loyalty in order to stably enter the market. To do this, customers should have a deep sense of trust and bond through the authenticity of the brand. At this time, among the components of brand authenticity, only corporate authenticity has a positive effect on customer brand attachment and loyalty. This paper suggests marketing strategies based on CSR activities that can most effectively show corporate authenticity. First, only cases where the activity was continued for more than one year and the activity contents and results were clear and recognized for authenticity were selected. Twenty cosmetic brands met this condition and 28 CSR activities which conducted by the brand are analyzed. The characteristics of each area were derived by dividing it into four areas of desirable society presented by the EU, and a marketing strategy for each type was presented. This research will be of practical help in conducting CSR activities later in the enterprise.

An approximately 10-fold higher level of adherence of Salmonella typhimurium strain TML to Int-407 cells was observed with organisms grown in Luria broth or in high-iron containing medium than those grown in low-iron containing medium. Iron specifically enhanced adherence, while other cations such as calcium, cobalt, copper, potassium, magnesium and manganese did not. It was suggested that iron did not act as a passive ligand - probably it stimulated production of bacterial factors necessary for adherence. A similar pattern of iron modulation of adhesiveness was also seen in Salmonella mutants with single or different combinations of multiple mutations in genes encoding the mannose sensitive hemagglutinin (type 1 fimbriae), mannose resistant hemagglutinin and flagellum. The adhesiveness of an isogenic fur mutant was modulated by iron in a manner similar to the wild-type strain, suggesting that iron modulation of adherence is independent of the fur gene product.
