The purpose of this study was to propose an efficient and feasible global market entry strategy for the Korean apparel industry by analyzing the Italian fashion industry. In particular, the study investigated the role of foreign exhibitions and showrooms supported and organized by Italian fashion organizations. The methodology for this study was to analyze industrial reports, review previous studies and conduct in-depth interviews with 23 industry experts in Italy, Korea and LA. The results indicated that the most prominent factor in the Italian fashion industry was the fashion cluster, which is a strong and organic network of diverse fashion related areas No matter the size of the enterprise, firms can get practical, prompt and efficient support from diverse associations. The network operated by the associations provides strong support to each firm by organizing collections and exhibitions, and providing promotional activities. Showrooms and agents are another supportive "gate keeper", directly related to an enterprise's sales. However, Korean fashion firms did not have enough information or knowledge for foreign exhibitions, nor did they make aggressive promotional efforts in the global market. Despite the many fashion-related associations exist in Korea, their programs are too focused on visible accomplishments and are too oriented on "big company" and "big voice", rather than many "small firms". In conclusion, the Korean fashion industry-particularly the fashion industry in Seoul-has strong potential to become the center of the global fashion market in the future. However, the fashion support system that can act as the channel to promote firms and to meet global buyers needs to be supplemented. To feasibly create this system, government or industry associations should develop a strong and generous support system and network, and they must recognize the need for small firms to exist.

Packages have been used for a wide variety of purposes, for protection, for display, for transportation of goods, or for keeping personal belongings. According to the demands of society and the times, liquor packages have been specialized and have appeared in almost every shape and size without restriction to cine particular type of material. In spite of its rapid development and wide application in our society, liquor package design has rarely been considered as a subject of comprehensive study. Majoring in package design, I have become especially interested in the area of liquor package design. I would like to explore liquor package design from several aspects. With the advent of new market and the rise of a new consumer society, advertising and mass media have expanded rapidly. While convenience of use is not a major issue, serving size certainly are quality, appeal of heritage and health concerns. Heritage is a major consumer appeal in Whisky, Beer, Wine and spirits. Designers have drawn heavily on the tradition of alcoholic products, have used type and graphics to create the illusion of heritage for new products. A sidelight to the heritage aspect of spirits package is the evolution of outer boxes for international liquors. International liquors package design illustrated the past and current themes. The design is contemporary and spare. Colored panels correlated to the liquor flavor used on clean white, black, gold boxes. While this research does not deny the impact of structural innovation and convenience package design , it does deny the existence of a graphic plateau. It is assumed therefore, that development in technology can facilitate communication between East and West. This can be accomplished because as containers of products are used in social setting, their form will gradually apply strong influence to the need for economical, easily handled, easily utilized packaging. Typically, ethnic package designs are those packages containing products which are prepared and marketed to a category of people who are prepared and marketed to a culture traits. They are liquor products sold in the metropolitan New York area which are marketed specially to Asians, Hispanics, or Eurpean population. These cultural groups share numerous traits including religion, language, dietary habits and traditional drinking styles. Therefore, the products which are familiar or common in their native countries are often imported or marketed there to serve them. These packages and products are frequently found on the shelves of supermarkets in predominantly ethnic areas. That is Korea, Japan if packaging is correctly design it would appeal to the American market. My research is that oriental beverage -Soju is good example of this precept. Assumedly, there must be a degree of subjectivity since it is a mean in which the consumers can relate to its advertising. This degree to relate and identify is the degree to which the package will be remembered and purchased. Subjectivity is intimately related to purchases since there is no such thing as a rational purchase in a society that operates on mass consumption. It is essential that packages become more personal human, entertaining, and more like advertising in order to maximize merchandising potential.

To investigate the effects of the improvement of postharvest quality on fresh tomato, antimicrobial microperforated (AMP) films were prepared and their antimicrobial abilities were observed. AMP films were made by coating different types of natural antimicrobial agents such as cinnamon, clove, and clary sage essential oils into microperforated (MP) films. Cinnamon essential oil of 10% (v/v) has proven to be very effective as inhibitor of the mold growth on tomato, compared to the clove and clary sage essential oils. Quality changes of fresh tomatoes packed using the natural AMP films (AMP10 and AMP30) and MP films (MP10 and MP30) during storage were evaluated. Total microbial growth, weight loss, firmness, lycopene content, and decay rate as the major quality parameters were monitored over 9 days at $15^{\circ}C$. The oxygen transmission rates and mechanical properties between the natural AMP and MP films were also compared. There was no significant difference in change of oxygen transmission rate, tensile strength and elongation between the AMP and MP films. For storage studies, the freshness of tomato packaged in AMP30 film was higher than that in OPP film (the control), MP10, MP30, and AMP10 films. Especially, AMP30 film exhibited high efficiency compared to the control for tomato decay during storage periods. Based on the results, the microperforation and antimicrobial properties of the packaged films may significantly affect the maintenance of an optimum gas composition within the package atmosphere for increasing the storage life and quality of produce. They were also effective on the inhibition of microbial growth by controlled release of antimicrobial agent at an appropriate rate from the package into the tomato. Natural antimicrobial agent coating microperforated films could use potential functional package as a method of extending the freshness of postharvest tomato for storage.

Traditional Korean fermented herbal plants are potential sources of new food that promote health, but they are still produced by yeast, fungi or bacteria fermentation. In the present work, mushroom (Paecilomyces tenuipes and Cordyceps militaris) fungal dongchunghacho were used to fermented Glycyrrhiza uralensis Fischer (licorice) or mixed with pupa. The pupa were tested as solid substrates for the production of corcycepin, liquiritin, and liquiritigenin. The fermented substrates were analyzed the content of cordycepin, liquiritin, liquiritigenin, and glycirrhizin productivity and inhibitory activity of NO. The cordycepin content of 70% EtOH extract from the fermented mixture of licorice and 50% pupa with C. militaris increased maximum at 33 times. Pupa was very excellent for the production of cordycepin. The liquiritin content was decreased in all the assays inoculated with P. tenuipes and C. militaris dongchunghachos. The liquiritigenin content was higher when fermented with P. tenuipes than C. militaris. The addition of pupa significantly reduced the liquiritin content and glycyrrhizin production. As a result, the liquiritigenin content increased in fermented P. tenuipes and C. militaris, and liquiritin and glycyrrhizin decreased. The inhibition of NO production in the different ethanolic extracts fermented with licorice and pupa was also significantly increased and higher than that of a nonfermented extract in higher polar solvent extracts. The contents of cordycepin and biological active compounds were altered in accordance with the concentration of pupa and fungi. This study provides basic data for use in developing dongchunghacho fungi as a functional food resource.

Chitosan, second largest biomass after cellulose on earth, has potential for use as functional food package due to its antibacterial activity. However, due to high melting temperature of chitosan, chitosan films have been made by casting method. Because gelatin has relatively low molting temperature depending upon amount of plasticizer added, it was added to chitosan to produce commercially feasible film. The objective of the current study was to determine optimum blend ratio and amount of chitosan/gelatin blend solutions against antibacterial activities for extruder resin. Gram-positive bacteria (Bacillus cereus ATCC 14579 and Listeria monocytogenes ATCC 15313) and -negative bacteria (Escherichia coli ATCC 25922 and Salmonella enteritidis IFO 3313) were used. Paper (8 mm) diffusion and optical density methods were used to evaluate effect of different blending ratio solutions on the inhibition of bacterial growth. Measured clear none size ranged from 8 mm to 18.07 mm in paper diffusion test. For B. cereus, E. coli, and S. enteritidis, addition of $50\;{\mu}L$ blend solution (chitosan/gelatin = 2/8: 0.3 mg) resulted in clear zone on paper disc. In L. monocytogenes, inhibition effect was observed with 0.6 mg chitosan (chitosan/gelatin=4/6). Minimum inhibitory concentration (MIC) values of B. cerues, L. monocytogenes, E. coli, and S. enteritidis with addition of chitosan were 0.1461, 0.2419, 0.0980, and 0.0490 mg/mL, respectively, These results indicate possibility of producing commercially feasible film with addition of optimum chitosan/gelatin amount.

Purpose PET-CT examinations using $^{18}F-FDG$ to treat urinary system cancer are limited in terms of anatomical structure and excretion route of $^{18}F-FDG$. But one of the ongoing examinations utilizing $^{11}C-Acetate$ can compensate for such defects. We would like to introduce a clinical application of $^{11}C-Acetate$ PET-CT in urinary cancer patients. Materials and Methods We conducted a clinical survey of 22 patients diagnosed with urinary cancer at our hospital, 10 prostate cancer patients, 10 renal cell carcinoma patients, and 2 bladder cancer patients. All patients were performed $^{18}F-FDG$ PET-CT examinations, $^{11}C-Acetate$ examinations were performed after two weeks on average. The equipment used to D-710 PET-CT in GE Company and we performed PET-CT procedures 15 minutes after injecting $^{11}C-Acetate$, and a medical doctor from the department of nuclear medicine appraised and compared images between $^{18}F-FDG$ and $^{11}C-Acetate$. Results According to our survey, prostate cancer patients generally had lower uptake of $^{18}F-FDG$ than other cancer patients did. In 2 out of 10 prostate cancer patients, metastasized cancer showed greater uptake in $^{11}C-Acetate$ than $^{18}F-FDG$. In renal cell carcinoma cases, 8 out of 10 patients displayed evidently greater uptake in $^{11}C-Acetate$ than $^{18}F-FDG$. We excluded bladder cancer cases in this study because uptake of $^{18}F-FDG$ in the bladder was too hot, the number of patients was insufficient, and the cases did not meet criteria such as the use of diuretics. Conclusion It is too premature to draw solid conclusions from the survey, since it involved only a small number of participants. However, there are a number of studies conducted abroad that prove the effectiveness of the $^{11}C-Acetate$ PET-CT examinations in treating urinary system cancer, and this study is still ongoing at our hospital. If the tests were to be conducted on a larger number of participants, this study could lead to numerous other potential research topics, such as the correlation between Prostatic specific antigen (PSA) values and $^{11}C-Acetate$ PET-CT, Gleason sum values from biopsy before surgery, Specificity, sensitivity, positive predictive value (PPV), negative predictive value (NPV) between $^{18}F-FDG$ PET-CT examinations and $^{11}C-Acetate$ PET-CT examinations in other urinary system cancers.

Peroxiredoxins (Prxs) are ubiquitously distributed and play important functions in diverse cellular signaling systems. The proteins are largely classified into three groups, such as typical 2-Cys Prx, atypical 2-Cys Prx, and 1-Cys Prx, that are distinguished by their catalytic mechanisms and number of Cys residues. From the three classes of Prxs, the typical 2-Cys Prx containing the two-conserved Cys residues at its N-terminus and C-terminus catalyzes $H_2O_2$ with the use of thioredoxin (Trx) as an electron donor. During the catalytic cycle, the N-terminal Cys residue undergoes a peroxide-dependent oxidation to sulfenic acid, which can be further oxidized to sulfinic acid at the presence of high concentrations of $H_2O_2$ and a Trx system containing Trx, Trx reductase, and NADPH. The sulfinic acid form of 2-Cys Prx is reduced by the action of sulfiredoxin which requires ATP as an energy source. Under the strong oxidative or heat shock stress conditions, 2-Cys Prx in eukaryotes rapidly switches its protein structure from low-molecular-weight species to high-molecular-weight protein structures. In accordance with its structural changes, the protein concomitantly triggers functional switching from a peroxidase to a molecular chaperone, which can protect its substrate denaturation from external stress. In addition to its N-terminal active site, the C-terminal domain including 'YF-motif' of 2-Cys Prx plays a critical role in the structural changes. Therefore, the C-terminal truncated 2-Cys Prxs are not able to regulate their protein structures and highly resistant to $H_2O_2$-dependent hyperoxidation, suggesting that the reaction is guided by the peroxidatic Cys residue. Based on the results, it may be concluded that the peroxidatic Cys of 2-Cys Prx acts as an '$H_2O_2$-sensor' in the cells. The oxidative stress-dependent regulation of 2-Cys Prx provides a means of defense systems in cells to adapt stress conditions by activating intracellular defense signaling pathways. Particularly, 2-Cys Prxs in plants are localized in chloroplasts with a dynamic protein structure. The protein undergoes conformational changes again oxidative stress. Depending on a redox-potential of the chloroplasts, the plant 2-Cys Prx forms super-molecular weight protein structures, which attach to the thylakoid membranes in a reversible manner.

A recent study showed that MTBE can be degraded by Fenton's Reagent (FR). The treatment of MTBE with FR, however, has a definite limitation of extremely low pH requirement (optimum pH $3{\sim}4$) that makes the process impracticable under neutral pH condition on which the ferrous ion precipitate forming salt with hydroxyl anion, which result in the diminishment of the Fenton reaction and incompatible with biological treatment. Consequently, this process using only FR is not suitable for in-situ remediation of MTBE. In order to overcome this limitation, modified Fenton process using NTA, oxalate, and acetate as chelating reagents was introduced into this study. Modified Fenton reaction, available at near neutral pH, has been researched for the purpose of obtaining high performance of oxidation efficiency with stabilized ferrous or ferric ion by chelating agent. In the MTBE degradation experiment with modified Fenton reaction, it was observed that this reaction was influenced by some factors such as concentrations of ferric ion, hydrogen peroxide, and each chelating agent and pH. Six potential chelators including oxalate, succinate, acetate, citrate, NTA, and EDTA were tested to identify an appropriate chelator. Among them, oxalate, acetate, and NTA were selected based on their remediation efficiency and biodegradability of each chelator. Using NTA, the best result was obtained, showing more than 99.9% of MTBE degradation after 30 min at pH 7; the initial concentration of hydrogen peroxide, NTA, and ferric ion were 1470 mM, 6 mM, and 2 mM, respectively. Under the same experimental condition, the removal of MTBE using oxalate and acetate were 91.3% and 75.8%, respectively. Optimum concentration of iron ion were 3 mM using oxalate which showed the greatest removal efficiency. In case of acetate, $[MTBE]_0$ decreased gradually when concentration of iron ion increased above 5 mM. In this research, it was showed that modified Fenton reaction is proper for in-situ remediation of MTBE with great efficiency and the application of chelatimg agents, such as NTA, was able to make the ferric ion stable even at near neutral pH. In consequence, the outcomes of this study clearly showed that the modified Fenton process successfully coped with the limitation of the low pH requirement. Furthermore, the introduction of low molecular weight organic acids makes the process more available since these compounds have distinguishable biodegradability and it may be able to use natural iron mineral as catalyst for in situ remediation, so as to produce hydroxyl radical without the additional injection of ferric ion.

This study was conducted to use oyster shells, which have caused environmental problems in the coastal of Korea, as an agricultural material after processing. Physico-chemical components and neutralizing amount on the Ihyun silt loam of crushed oyster shell and slaked lime were examined. In field experiment, the properties of the soil, growth and yield of lettuce, cabbage, spinach, onion, red pepper and soybean were examined by the treatments of the shell(3.68ton/ha) or the lime (2.76ton/ha) with a randomized block design. Particle size of crushed oyster shell consisted of 73.4% of 1~60mesh and 26.6% larger then 61 mesh and contents of CaO, OM, and $P_2O_5$, etc. were 55.5%, 1.3%, and 0.29%, respectively. The requirement of the shell to neutralize the soil was 130~135% of the lime, but after 24months, it was the same. The application of the shell increased the contents of available $P_2O_5$ and $SiO_2$ exchangeable Ca in used soil. The shell tratment increased the leaf height, leaf width, etc. of the examined plants, and the yields 6~154% according to examined plants, as compared with the nonliminged, indicating that the shell possesses a great potential as an agricultural material with the same effectiveness as the lime.

[ $\underline{Purpose}$ ]: We performed a retrospective non-randomized clinical study of locally advanced rectal cancer, to evaluate the anal sphincter preservation rates, down staging rates and survival rates of preoperative chemoradiotherapy. $\underline{Materials\;and\;Methods}$: From January 2002 to December 2005, patients with pathologically confirmed rectal cancer with clinical stage T2 or higher, or patients with lymph node metastasis were enrolled in this study. A preoperative staging work-up was conducted in 36 patients. All patients were treated with preoperative chemoradiotherapy, and curative resection was performed for 26 patients at Hallym University Sacred Heart Hospital. Radiotherapy treatment planning was conducted with the use of planning CT for all patients. A total dose of $45.0{\sim}52.2\;Gy$ conventionally fractionated three-dimensional radiotherapy was delivered to the whole pelvis. Chemotherapy was given at the first and fifth week of radiation therapy with continuous infusion i.v. 5-FU (Fluorouracil) and LV (Leucovorine). Surgical resection was performed 2 to 4 weeks after the completion of the chemoradiotherapy regimen. $\underline{Results}$: The complete resection rate with negative resection margin was 100% (26/26). However, a pathologically complete response was not seen after curative resection. Surgery was done by LAR (low anterior resection) in 23 patients and APR (abdomino-perineal resection) in 3 patients. The sphincter preservation rate was 88.5% (23/26), down staging of the tumor occurred in 12 patients (46.2%) and down-sizing of the tumor occurred in 19 patients (73%). Local recurrence after surgical resection developed in 1 patient, and distant metastasis developed in 3 patients. The local recurrence free survival rate, distant metastasis free survival rate, and progression free survival rate were 96.7%, 87% and 83.1%, respectively. Treatment related toxicity was minimal except for one grade 3, one grade 4 anemia, one grade 3 leukopenia, and one grade 3 ileus. $\underline{Conclusion}$: Preoperative concurrent chmoradiotherapy for locally advanced rectal cancer seems to have some potential benefits: high sphincter preservation and down staging. Treatment related toxicity was minimal and a high compliance with treatment was seen in this study. Further long-term follow-up with a larger group of patients is required.
