TV news anchor woman's appearance, voice, expression, and clothing, etc., have an influence on the reliability of the article to be reported. Among these, clothing is the most crucial factor in forming an anchor woman's image, especially the clothing color factor. This study is aimed at providing the basic foundation for anchor woman when they select the clothing color by analyzing the clothing color image on the screen. For this purpose, the KBS and MBC 9 o'clock news desk and SBS 8 o'clock news of the local major news programs were selected. With the collection of 300 pieces of news clips related to anchor woman's clothing from January to December 2008, they were classified into F/W seasons and analyzed by the clothing color. The surveying method of clothing color was to capture the anchor woman's clothing among the news clips, then pick the representing color by applying Adobe Photoshop, and researching the formed $L^*a^*b^*$ value of color chips. The surveyed color was transformed into value of distant cell, H V/C, and the results were analyzed. As a result, it showed that the White system for anchor woman's clothing during the S/S seasons is most frequently picked, followed by the Red system. In F/W seasons, Gray system is the most favored, then White and Red, respectively. It was revealed that the most frequently selected colors for upper-wear by anchor women in the three broadcasting stations was an achromatic color, such as White or Gray, and then the chromatic color, Red. It shows that there is no big difference in season. The Inner-wear color matched the jackets which were also achromatic in color, white and black being the most favored in the S/S seasons, and in the case of chromatic colors, Red was the most favored. In addition to this, identical coloration with jacket, coloration with similar color, or single color as clothing color were no less frequently adopted. During the F/W seasons, identical coloration accounts for 26%, the most popular colored being White and Red. It was found that the coloration with achromatic colors are highly favored in the three major broadcasting stations alike.

Cosmetic products including skin and essence were manufactured to analyze the effect of green tea polyphenols addition. In addition, irradiation was applied to remove an undesirable color of green tea polyphenol(GTP), which may cause a problem in the marketing, of a final product; moreover, comparative studies were conducted with the cosmetic products on whether or not antiseptics were treated to verify its use for the development of non-antiseptic cosmetic products. Growth inhibition zones were shown in the microbial study except for Candida albicans. The minimum inhibitory concentration(MIC) of E. coli and C. albicans was 2,500 ppm but that of S. aureus was 1,000 ppm. The numbers of E. coli and S. aureus were reduced to undetected levels when 10,000 and 5,000 ppm of polyphenol were added, respectively. Results indicate that the addition of irradiated green tea polyphenol provides a good method to manufacture functional cosmetics including skin and essence with various biological activities such as antimicrobial activity without antiseptics.

The objective of this study was to evaluate microbial growth patterns on Korean foods containing collagen. Samgyetang, Ugultang, Odolbyeboguem, Jeonyak, and Jokbal were inoculated with Staphylococcus aureus and Salmonella spp., and incubated at $4^{\circ}C$ (6 days), $10^{\circ}C$ (6 days), $20^{\circ}C$ (3 days), and $30^{\circ}C$ (36 h). Cell counts of S. aureus and Salmonella spp. were enumerated on mannitol salt agar and xylose lysine deoxycholate agar, respectively. Of the 5 foods, S. aureus and Salmonella cell counts decreased (P < 0.05) only in Jeonyak. To understand this reduction in cell growth on Jeonyak, extracts of ingredients such as clove, cinnamon, pepper, ginger, and jujube were examined to determine minimal bactericidal concentrations (MBC; AU/mL). Clove (3.13 AU/mL), cinnamon (50 AU/mL), pepper (25 AU/mL), and ginger (50 AU/mL) extracts displayed antimicrobial activity against S. aureus, and clove and cinnamon extracts displayed antimicrobial activity against Salmonella. The results indicate that Jeonyak has antimicrobial activity against S. aureus and Salmonella, and clove and cinnamon are the primary antimicrobial agents in this food.

The sensitivity of various pathogenic bacteria(Listeria monocytogenes, Staphylococcus aureus, Aeromonas hydrophila, Escherichia coli O157:H7 and Salmonella typhimurium) to the pine needle and green tea extracts was tested. Water extract of pine needle(PNW), 70% ethanol extract of pine needle(PNE), water extract of green tea(GTW) and 70% ethanol extract of green tea(GTE) were prepared for the test of antibacterial activty. Tryptic soy broth(TSB) containing 0∼2%(w/v) of pine needle and green tea extracts were inoculated with 10$\^$5/∼10$\^$6/ cells/ml of each bacterium and incubated at 35$\^{C}$ for 24 hours. The standard plate count method was used to measure the inhibitory effect of the extracts. Minimum inhibitory concentration(MIC) and minimum bactericidal concentration(MBC) were derived from the survival curves of pathogenic bacteria. Antibacterial activities of the pine needle and green tea extracts were compared with that of sodium benzoate, a preservative, by clear zone test. L. monocytogenes, S. aureus and A. hydrophila were completely inhibited at 0.4∼1.6% level while E. coli and S. typhimurium were very resistant to the pine needle extracts. Green tea extracts completely inhibited all strains tested at 0.2∼1.0% level and bactercidal to all strains except L. monocytogenes at 0.5∼2.0% level. Antibacterial activities of pine needle and green tea extracts were stronger than that of sodium benzoate. The order of antibacterial activities of pine needle and green tea extracts to the pathogenic bacteria was GTE > GTW > PNE > PNW. This result suggests that green tea extracts can be used as an effective natural antibacterial agent in food.

The purpose of this study was to analyze information about food and nutrition presented through the television broadcast media, with the aim of finding out the optimal communication method for supplying the general public with accurate information. To perform this study, a total of sixteen monitoring people were recruited and trained before and during the study. Five domestic TV channels were selected to be monitored, and the total monitoring period was six months. For maximum efficiency, the monitoring people were assigned to 8 teams. The results of the present study can be summarized as follows : First, the total reported cases of information about food and nutrition were 237, of which about 30% were judged appropriate and 70％ as inappropriate. Second, classifying each case by program type, information programs made up the highest portion at 82 cases (34.6%), cooking programs accounted for 76 cases (32.1%), news programs for 40 cases (16.9%), and entertainment programs for 7 cases (3.0%). The analysis showed that the greatest amount of incorrect information was found in dramas, followed by entertainment, information, cooking and news programs. Third, classifying each case by theme of contents monitored, meal preparation and cookery made up the highest portion at 86 cases (36.3%), foods accounted for 67 cases (28.3%), disease and diet-therapy for 40 cases (16.9%), eating habits for 31 cases (13.1%), and diet and fitness for 13 cases (5.5%). Incorrect information was conveyed most often on the themes of food habits, foods, disease and diet-therapy, cookery, and diet and fitness. Fourth, classifying each case by channel, Cable TV had the highest frequency at 72 cases (30.4%), MBC had 51 cases (21.5%), SBS had 43 cases (18.1%), KBS1 had 41 cases (17.3%) and KBS2 had 30 cases (12.7%). In conclusion, systematic monitoring should be continued to reduce the frequency of incorrect information being broadcast and to help ensure that accurate information is conveyed to the general public. Moreover, there should be a system of cooperation to provide information to help broadcast production teams establish a strategic program. Finally, it is essential to organize an advisory team by promoting links between the mass media and specialists in the field, and to develop an educational program on nutrition to help ensure the communication of accurate information on food and nutrition.

Article 17 and 18 of the Korean Constitution respectively prescribe the violation of individual's right to privacy and the secrecy of wire communication. Meanwhile, Article 20 of the Criminal Code provides that an act which is conducted within the ambit of laws or pursuant to accepted business practices or which does not violate the social norms shall not be punishable. In 1999, the Constitutional Court held that media reports on public matters of public figures must be given strong constitutional protection, and treated differently from reports on private matters of private figures. In accordance with the decision, the Supreme Court has expanded the scope of constitutional guarantee of freedom of expression since 2002. This study analyzes the issue of media liability for publication of illegally intercepted wire communication by a third person. Particularly, it reviews Seoul High Court's ruling on 'X-file scandal' which disclosed intercepted wire communications between notable public figures regarding a slush fund for a presidential candidate. In the light of this analysis, the study concludes that the media reporting of the intercepted communication does not violate social norms of Article 20, and therefore it is entitled to a constitutional privilege.

Plant extract has attracted considerable interest in oral disease therapy. The present study was performed to observe the antibacterial effect on cariogenic Streptococcus mutans GS5 and Streptococcus sobrinus 6715, and periodontopathic Actinobacillus actinomycetemcomitans Y4 of phytoncide from Chamaecyparis obtusa Sieb. et Zucc employing the measurement of optical density, viable cell counts, and antibiotic sensitivity. The results were as follows: 1. Minimum inhibitory concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was observed to be 0.5%, 1%, and 0.2%, respectively. 2. Minimum bactericidal concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was determined to be 0.5%, 2%, and 0.2%, respectively. 3. The bacteria exposed to the phytoncide become more sensitive to antibiotics. The phytoncide enhanced significantly antibacterial activity of ampicillin against S. mutans and S. sobrinus. It also increased significantly the activity of penicillin and amoxicillin against S. sobrinus. In contrast, the phytoncide augmented the activity of amoxicillin and cefotaxime against A. actinomycetemcomitans but the increase was not statistically significant. The overall results indicate that phytoncide from Chamaecyparis obtusa Sieb. et Zucc used for this study has a strong antibacterial activity against cariogenic and periodontopathic bacteria and that it also has permeabilizing effect on certain antibiotics against these bacteria. Therefore, the phytoncide may be used as a candidate for prevention and therapeutic agent against oral infectious disease including dental caries and periodontal disease.

Background: Preclinical studies have shown that the combination of an aromatase inhibitor (AI) and capecitabine in estrogen receptor (ER)- positive cell lines enhance antitumor efficacy. This retrospective analysis of a group of patients with metastatic breast cancer (MBC) evaluated the efficacy and safety of combined AI with capecitabine. Materials and Methods: Patients with hormone receptor-positive metastatic breast cancer treated between 1st January 2005 and 31st December 2010 with a combination of capecitabine and AI were evaluated and outcomes were compared with those of women treated with capecitabine in conventional dose or AI as a monotherapy. Results: Of 72 patients evaluated, 31 received the combination treatment, 22 AI and 19 capecitabine. The combination was used in 20 patients as first-line and 11 as second-line treatment. Mean age was 46.2 years with a range of 28-72 years. At the time of progression, 97% had a performance status of <2 and 55% had visceral disease. No significant difference was observed between the three groups according to clinical and pathological features. Mean follow up was 38 months with a range of 16-66 months. The median PFS of first-line treatment was significantly better for the combination (PFS 21 months vs 8.0 months for capecitabine and 15.0 months for AI). For second-line treatment, the PFS was longer in the combination compared with capecitabine and Al groups (18 months vs. 5.0 months vs. 11.0 months, respectively). Median 2 year and 5 year survival did not show any significant differences among combination and monotherapy groups. The most common adverse events for the combination group were grade 1 and 2 hand-for syndrome (69%), grade 1 fatigue (64%) and grade 1 diarrhoea (29%). Three grade 3 hand-foot syndrome events were reported. Conclusions: Combination treatment with capecitabine and AI used as a first line or second line treatment was safe with much lowered toxicity. Prospective randomized clinical trials should evaluate the use of combination therapy in advanced breast cancer to confirm these findings.

The contents provided by the terrestrial broadcasters have governed the market based on their excellent quality in Korea. In spite of the launching of various pay TV services focusing on multi-channel, it is not yet easy to find out the substitutionary pay TV channels for the terrestrial. Therefore, the real time retransmission of the terrestrial channels brings about the crucial effects on the pay TV's competency, especially on the new media as the invisible barrier. So it is frequently proposed to change the aim of the retransmission policy from the universal access to the promotion of media industries. The retransmission can be divided into two types as the must carry and retransmission consent. In Korean situation, keeping or reducing the must carry channel would be appropriate rather than expanding them. However, periodic investigation into the public effects of the must carry is necessary, instead of it. Moreover, the rational and fair monetary compensation for the commercial channels(MBC, SBS, KBS2) is arising as the bottle neck in the retransmission agreements between the broadcasters. The conjoint analysis was carried out to estimate the welfare growth from the retransmission, based on the stated preference from the audiences' point of view. For must carry channels, it was certified as the 'win-win' strategy for both sides and audiences. For the commercial channels, it is revealed to be beneficial to the audiences. Thereafter, the standards for the rational price were suggested to promote the retransmission. This can contribute for inspiring the dynamic vitality to the media industry by reinforcing the contents competencies and for establishing the long term growth strategies.

Recently interesting in development of antimicrobial agent from natural origin has been increased in these days. Many studies have been reported antimicrobial effect of Horseradish(Armoracia rusticana) root extracts against various microorganisms such as Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Vibrio parahaemolyticu, Staphylococcus aureus, Bacillus subtilis, Aspergillus parasiticus, Helicobacter pylori. The main component related to antimicrobial activity in horseradish is well known as allyl isothiocyanate(AIT). In this study, we investigated the antimicrobial effects of Horseradish(Armoracia rusticana) root extracts against Streptococcus mutans isolated from human dental plaque, Streptococcus mutans reference strain and compared with that of chlorhexidine. Horseradish root extracts and chlorhexidine were tested to determine their minimum inhibitory concentration( MIC) and minimum bactericidal concentration(MBC). The result of this study can be summerized as follows; 1. Horseradish root extracts showed antimicrobial effect against both S. mutans isolated strain and reference strain, their MIC were respectively $0.083{\sim}0.25%$ ($833.33{\sim}2500 ppm$), 0.25% (2500 ppm). Horseradish root extracts showed antimicrobial effect against S. mutans isolated strain at same or slightly lower concentration compared with MIC of reference strain. 2. $0.083{\sim}0.25%$ horseradish root extracts showed similar antimicrobial effect with chlorhexidine ($0.0021{\sim}0.0041%$).
