  • This study aims to analyze color characteristics centered by women's suit styles that represent masculinity remarkably. Through this, it figures out color's type and continuance availability as a representing tool to express masculinity to provide useful color information which can be applied effectively to various color planning. For this research, related images were collected among women's pants suits appeared in $2004{\sim}2006's$ Paris, London, New York and Milan collection F/W that are most similar to modern man's suit. Among them, the study analyzes 319 pictures where the features of masculinity were represented effectively. The referred color values were earned by converting $L^*a^*b^*$ values measured through the color extracting tool of Computer program (Adobe Photoshop CS) and color tone characteristic were analyzed by classifying 12 color PCCS and 5 achromatic colors. The result of the study are as follows: First, based on standard of color hue and tone, in terms of color hue, PB, YR, Y were frequently shown up but G, BG series were not found much after analyzing overall women's pants suit color characteristics shown in $2004{\sim}2006$ Paris, London, New York and Milan collection. Second, the color analysis about 3years of $2004{\sim}2006$ tells that achromatic colors have been most widely used in every year. In terms of color hue, PB, YR, Y series were appeared most popular and G, BG classes weren't appeared frequently. In addition, once looking at yearly color tone distribution trend, like overall color tone distribution result, Bk, w, dkg, g, p were highly used as sequential and b, v, dp, sf, ItGy series show low distribution level. And such a distribution level of low and high in frequency has been showed continuously as a similar style. Accordingly, through the study, as a tool to express masculinity in women's suit, achromatic colors like black and white series and PB, YR, Y series color were investigated as most popular uses. And as color tones, Bk, w, dkg, g, p were used frequently.

  • The antimicrobial effect of the methanol extract of Inula britannica flowers against methicillin resistant Staphylococcus aureus (MRSA) was investigated. It was confirmed that the methanol extract is mainly composed of quercetin, which has antimicrobial properties. The antimicrobial effect of the methanol extract against 3 MRSA strains was determined by the disc diffusion method. The minimal inhibitory concentrations were ranged from 0.625 mg/ml to 1.25 mg/ml, and the minimum bactericidal concentrations were 2.5 mg/ml. Time kill kinetics revealed bactericidal activities, and the morphological alterations in S. aureus ATCC 33591 treated with the extract were observed using a scanning electron microscope. The methanol extract affected the expression of the resistant genes, mecA, mecI, and mecRI in mRNA. Therefore, the methanol extract of I. britannica flowers clearly demonstrated an antimicrobial effect against MRSA and these results suggest a potential for application as a natural antimicrobial agent.

  • Bovine mastitis, defined as an inflammation of the mammary gland, is usually associated with bacterial infection. Thus, treatment and control of mastitis relies primarily on antimicrobial therapy. This study investigated the bactericidal actions of silver ion against causing various bovine mastitis pathogens. Minimal inhibitory concentrations (MICs), minimum bactericidal concentrations (MBCs) and bactericidal activity times and concentrations of silver ion against pathogens were determined. The effect of silver ion on bacterial morphology was studied by scanning electron microscopy (SEM). The MICs and MBCs of silver ion for various bacteria strains ranged from 1.9-15.6 ${\mu}g$/ml. SEM images indicated formation of a pit, distortion and disruption of cell walls in silver treated Staphylococcus aureus and Escherichia coli. The results demonstrate that silver ion has a bactericidal capacity against causing various pathogens of bovine mastitis and suggest that silver ions may be exploitable as a therapeutic/preventative tool of bovine mastitis.

  • 디지털 컨버전스와 유비쿼터스 시대의 시작은 디지털 미디어 기술의 발전과 방송 통신 사업의 컨버전스를 가속화 시켰으며, 그 결과로DMB, WCDHA, Wibro, IP-TV, HSDPA 등의 새로운 형태의 차세대 제품과 서비스들이 뉴미디어 매체의 핵심으로 등장하고 있다. 국내에서 방송 통신의 컨버전스의 빠른 진행은 세계 최초로 디지털 멀티미디어 방송(DMB) 서비스 시작을 가능하게 하였다. DMB 서비스는 멀티미디어 서비스가 핵심이다. DMB 데이터 서비스인 Broadcasting Website Service(BWS)는 현재 지상파 DMB방송 사업자인 KBS, MBC, SBS, YTNDMB가 본방송 준비 막바지 단계이며, 삼성 전자와 LG전자를 비롯한 단말기 개발사들도 데이터 서비스를 위한 제품 출시에 서두르고 있는 등 DMB 산업의 활성화의 주역이 될 것으로 예상된다. DMB의 데이터 서비스는 뉴스, 날씨, 프로그램 정보 등의 단순 정보보기 수준에 그치지 않고, 리턴 채널을 이용한 양방향 서비스와, SMS, 전화걸기 등 휴대전화 단말의 고유기능과의 연계를 통한 다양한 서비스도 선보일 것이다. 더 나아가 향후 T-Commerce와 개인 광고 등 새로운 비즈니스 모델과 사업영역으로 확산시켜 나갈 수 있을 것이다. 그러나, 아직까지 DMB와 데이터 서비스는 초기단계로서, 표준 기술의 규격 작업, 이론적 논의들, 관련 사업자들의 비즈니스 준비 등에서 검토되어, 실제 사용자들을 대상으로한 연구 분석이 이루어 지지 않았다는 연구의 한계를 가지고 있다. 본격적으로 방송, 통신 컨버전스 데이터 서비스가 시작되면서, 사용자들에 초점을 맞춘 많은 연구가 이루어지길 바라며, 이러한 연구의 분석를 통해 또 다른 새로운 서비스와 비즈니스 기회의 창출을 기대해 본다.여 RD(Rate Distortion) 최적화 기반 모드 결정을 빨리 완료함으로써 고속 프레임간 모드 결정을 가능하게 한다. 제안된 방법은 프레임 간 모드 결정을 고속화함으로써 스케일러블 비디오 부호화기의 연산량과 복잡도를 최대 57%감소시킨다. 그러나 연산량 감소에 따른 비트율의 증가나 화질의 열화는 최대 1.74% 비트율 증가 및 0.08dB PSNR 감소로 무시할 정도로 작다., 반드시 이에 대한 검증이 필요함을 알 수 있었다. 현지관측에 비해 막대한 비용과 시간을 절약할 수 있는 위성영상해석방법을 이용한 방법은 해양수질파악이 가능할 것으로 판단되며, GIS를 이용하여 다양하고 복잡한 자료를 데이터베이스화함으로써 가시화하고, 이를 기초로 공간분석을 실시함으로써 환경요소별 공간분포에 대한 파악을 통해 수치모형실험을 이용한 각종 환경영향의 평가 및 예측을 위한 기초자료로 이용이 가능할 것으로 사료된다.염총량관리 기본계획 시 구축된 모형 매개변수를 바탕으로 분석을 수행하였다. 일차오차분석을 이용하여 수리매개변수와 수질매개변수의 수질항목별 상대적 기여도를 파악해 본 결과, 수리매개변수는 DO, BOD, 유기질소, 유기인 모든 항목에 일정 정도의 상대적 기여도를 가지고 있는 것을 알 수 있었다. 이로부터 수질 모형의 적용 시 수리 매개변수 또한 수질 매개변수의 추정 시와 같이 보다 세심한 주의를 기울여 추정할 필요가 있을 것으로 판단된다.변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실증결과를 통하여 한국주식시장에

  • The study attempts to introduce 'Gotcha Journalism' to the Korea journalism, research and analyze it. Gotcha journalism is the journalistic reporting attitude that the journalists repeatedly and intensively reports public figures, especially politicians' mistakes or happening. 'Gotcha' is abbreviation of "I got you", frequently used in the English and American culture. In order to get the goal of this study, several journalists who are currently working for Chosun, Joongang, Dong-a, Hangyore, Kyunghyang and Seoul, national covering daily newspapers. In addition, the reporters who work for KBS, MBC, and SBS were Interviewed. All journalists who have been worked more than 5 years at the politic department were selected as interviewees. Thus, Intensive interviews are prime source of this study. Based the result of the research, gotcha journalism is externally derived from obsessive interest of Korean people to politics. Internally, it is easy to report happening or mistakes rather than big argument or ideological agenda of the politicians as news for journalists and to catch readers. In addition, the competition with advertising income accelerates this situation. And gotcha journalistic reporting behavior or attitude highly relates to political propensity of the newspapers or broadcastings. Especially some of the newspapers take gotcha journalism as a political struggling tool. It is appeared that another major cause for gotcha journalistic reporting behavior is customer-driven news production.

  • This study examines why follow-up investigative programs about the sinking of the Cheonan Patrol Combat Corvette(ROKS Cheonan) have not been produced, despite much speculation surrounding the cause of the sinking since November 2010, when KBS investigative program, In-Depth 60 Minutes which had covered the incident was aired. We have uncovered four reasons through a series of in-depth interviews with producers and reporters, as follows. First, Korean military authorities monopolized relevant information, while the producers could not prove or confirm the validity of the findings of the JIG(Joint Civilian-Military Investigation Group)'s report because the facts had been revealed partially and selectively by the authorities and the press' scientific investigation were rejected by the authorities. Second, the crew of In-Depth 60 Minutes was subjected to severe disciplinary action by the Korea Communications Commission. This caused a chilling effect, - it broke the producers' resolve to further explore the reason behind the sinking. Furthermore, the screening of the investigative documentary, Project Cheonan Ship was cancelled without prior notice, presumably by the power of the State and markets. Third, the reorganization and shake-up of personnel by broadcasting stations' presidents appointed by the power of the State crushed the spirit of PD Journalism. Finally, the "red purge" factions stigmatized by the political or military, or the mainstream press, caused the producers or broadcasters to engage in self-censorship. The idea has been used in Korea as a smoke screen to deflect public attention. Nevertheless, the producers hope to shed light on the Cheonan sinking incident and to prove reasonable doubts by pursuing follow-up investigations.

  • The antimicrobial effects of ten isothiocyanates (ITCs) present in cruciferous vegetables and radish root hydrolysate were investigated against pathogenic bacteria from olive flounder. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were measured against two gram-positive bacterial strains (Streptococcus parauberis, S. iniae) and four gram-negative bacterial strains (Edwardsiella tarda, Vibrio ichthyoenteri, V. harveyi, Photobacterium damselae) by using a broth microdilution technique. The antibacterial activity of ITCs was in the order sulforaphane > sulforaphene > phenylethyl ITC > erucin > benzyl ITC > iberin > I3C > allyl ITC > phenyl ITC > hexyl ITC. The susceptibility of fish pathogens to ITCs was in the order of V. harveyi > E. tarda > P. damselae > S. parauberis > S. iniae > V. ichthyoenteri. Antimicrobial activity (MIC) of radish root hydrolysate was 0.250 mg/mL against S. iniae, 0.438 mg/mL against S. parauberis, and 0.500 mg/mL against both E. tarda and V. harveyi. The aliphatic ITCs were potent inhibitors of the growth of fish pathogens, followed by aromatic ITCs and indolyl ITC. The presence of a double bond in the chemical structure of ITCs decreased antibacterial activity, while ITCs with a thiol (-S-) group and a longer carbon chain increased antibacterial activity. These results suggest that ITCs have strong antibacterial activities and may be useful in the prevention of fish pathogens.

  • The limitation and scarcity of broadcasting waves provide important rationale behind the idea of public ownership of broadcasting waves which can facilitate communications among people with diverse backgrounds and values in the society. Independence of broadcasting industry from the regulatory organization is imperative for the broadcasting industry to serve the public interest that has been historically defined by each county. For the Korean broadcasting industry, history of modern Korea taught us that the broadcasting regulatory organizations such as Korea Communications Commission(KCC) should be kept from any political influence for the industry to best serve the public. Recent controversies on the role of the CEO of KBS and the appointment of the CEO of YTN by the president of the country provide evidence that the independence of broadcasting in Korean society is a critical topic. This study examined the corporate structures of broadcasting industry and the political independence of the industry in relation to the changes in the concept of public interest and the role of broadcasting. It is critically important to investigate the political independence of broadcasting in Korea because the core argument of independence of broadcasting which is about the freedom of expression protected by the constitution is still contested in the country. For the purpose of collecting diverse perspectives on broadcasting, survey method was adopted in this study. Three groups Abstracts 697 of participants were recruited: reporters, experts in the field, and regular citizens. The result indicated that the independence of broadcasting was in the process of deterioration. Also, the participants of the study understood that it was impossible for the broadcasting to serve the public interest when the broadcasting was not free from the influence of regulatory institutions such as KCC.

  • Pure Bombus ignitus venom samples were submitted to two-dimensional gel electrophoresis. A total of 64 excised spots were analyzed by mass spectrometry. Three main proteins resulted in the identification have not been described in other bee venoms before. Dose-dependence against human carcinoma (Hep3B, BT-20, A549 and AGS) were observed from 1ng/ml to 100ng/ml. Expecially, the treatment of 100ng/ml B. ignitus venoms showed the highest cytotoxicity with 55% against hepatocellular carcinoma (Hep3B). The B. ignitus venoms showed strong antimicrobial activities against Enterococcus faecium and Shigella sonnei, and practically antimicrobial activity against the other microorganisms tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of E. faecium and S. sonnei, were 0.256ug/ml, respectively.

  • Recently nano particles have proven for wide array of bioactive properties. In the present study, antibacterial properties of chitosan silver nano composites (CAgNCs) were investigated against fish pathogenic Edwardsiella tarda. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of CAgNCs against E. tarda were $25{\mu}g/mL$ and $125{\mu}g/mL$, respectively. The field emission scanning electron microscope (FE-SEM) image of CAgNCs treated E. tarda showed the strongly damaged bacteria cells than non-treated bacteria. Furthermore, treatment of CAgNCs induced the level of intracellular reactive oxygen species (ROS) in E. tarda cells in concentration and time dependent manner suggesting that it may generate oxidative stress leading to bacterial cell death. In addition, MTT assay results showed that the lowest cell viability at $100{\mu}g/mL$ of CAgNCs treated E. tarda. Overall results of this study suggest that CAgNCs is a potential antibacterial agent to control pathogenic bacteria.
