새로운 광고 매체의 분류를 어떻게 할 것인가?

차유철(You Cheol Cha) 한국광고홍보학회 2007 한국광고홍보학보 Vol.9 No.4

최근 디지털 매체 외에도 새로운 형태의 광고 매체들이 속속 등장하고 있지만, 대부분 아직 제대로 분류되거나 명칭을 부여받지 못하고 있다. 이들 대부분의 공통점은 주로 가정 밖에서 접할 수 있다는 점에서 옥외광고의 관점에서 접근하였다. 연구의 내용은 이들을 반영하여 옥외광고를 새롭게 정의하고, 이들을 포함하는 분류체계를 설정하고, 이들에 대한 명명을 하는 것이다. 이러한 연구목적을 위해 문헌연구와 사례연구를 병행하였다. 연구 결과, 옥외광고는 "가정 이외의 공간에서 지각 가능한 광고 메시지를 전달하는 매체 중기 분류된 광고 매체를 제외한 모든 매체를 말한다"라는 정의를 내렸다. 기존 분류체계에 새로운 옥외광고 매체들을 포함시키는 방법으로 첫째, 기존 분류체계에 새로운 광고 매체를 완전히 포함시키면서 하위 유형에 추가적인 항목을 추가하는 방법과, 둘째, 기존 분류체계에 새로운 광고 매체를 별도의 영역으로 설정하는 방법을 제안하였다. 새로운 광고 매체의 명칭은 ``편재 매체(Omnipresent Media)``와 ``주변 매체(Surrounding Media)``의 두 가지 대안을 제시하였다. 본 연구는 새로운 광고 매체에 대한 연구는 아직 다뤄진 적이 거의 없었다는 점, 광고 매체의 지평을 넓힌다는 점에서 의미가 있다고 하겠다. The objects of this study is to re-define and re-classify the outdoor advertising, and name the new advertising media. There are very many new advertising media but most of them are not still get any particular name and enough attention. Most of those new advertising media would be classified in outdoor advertising category. So the researcher studied this research from the view point of outdoor advertising. This study used two types of research methods, literature study and case study. literature study was done by investigating laws, research reports, articles in academic journals, and books. Case study also was done by reviewing new media advertisements. By scrutinizing the preexistent definition of outdoor advertising and new advertising media characteristics, this study re-defined outdoor advertising as ``all media, except the preclassified advertising media, that communicate perceptible advertising message out of home space.`` This study also re-classified outdoor advertising into two types by including new advertising media which had been neglected in classified tables. By reflecting the characteristics of wide range of new advertising media, the researcher proposed two names; Omnipresent media; Surrounding media. Even though this study has some limitations, it may be meaningful that it proposed the latest definition on outdoor advertising and named the new advertising media first time.

방송광고 사전심의 폐지 전후의 광고 창의성과 윤리성에 관한 광고인 인식 연구

차유철(You Cheol Cha) 한국광고홍보학회 2011 한국광고홍보학보 Vol.13 No.4

2008년 6월, 한국광고자율심의기구에서 시행하던 방송광고 사전심의가 위헌판결을 받았다. 사전심의는 광고윤리를 확립하고, 광고의 자율성과 신뢰도를 진작시키며 사회적 책임을 제고하기 위하여 제정한 것인데, 한편으로는 방송광고의 표현의 자유를 부분적으로 제한하였다. 즉 사전심의의 주요 쟁점은 광고 윤리성과 광고 창의성의 충돌이라고 할 수 있는데, 사전심의 폐지 이후 어떤 변화가 있었는지를 알아보는 것이 이 연구의 주된 목적이다. 연구는 광고인들을 대상으로 사전심의 폐지 전과 후에 광고 윤리성과 광고 창의성에 대한 인식이 어떤 차이를 보이는지를 알아보았다. 그 결과, 광고인들은 사전심의 폐지 후 광고 창의성이 높아졌고, 외국어 사용과 비교 광고가 늘은 것으로 인식하고 있었다. 광고 창의성의 경우, 직종(크리에이티브-기획), 경력(10년 이하-10년 초과), 성별과 관계없이 유사한 인식 변화를 보였다. 그러나 외국어 사용에 대해서는 경력이 많은 집단이 적은 집단보다 더 늘어난 것으로 인식하고 있었다. 광고 윤리성에 대해서는 사전심의 폐지 후 윤리적 인식이 낮아진 것으로 나타난 반면, 사전심의가 광고 윤리성에 미치는 영향은 유의하지 않은 것으로 나타났다. 이러한 연구결과는 사전심의 폐지 후의 변화를 실증적으로 검증했다는 점, 심의가 미치는 영향에 대한 추론의 단서를 제공했다는 점, 유사한 사례, 즉 제도의 제정과 폐지에 대한 고려점을 제공했다는 점에서 의미가 있다고 하겠다. On June 28, 2008, forehand review for broadcasting advertisements was found unconstitutional. Pre-screening had been legislated to establish advertising ethics, enhance autonomy and credibility of advertising, and let advertising fulfill social responsibility, but. in the one hand, it had restricted freedom of expression of broadcasting advertisements. The major issue of pre-screening was the collision between advertising ethics and freedom of expression. The main purpose of this research is to find out what has happened since after pre-screening was abolished. This research has studied the differences of advertising people`s perception about advertising ethics and advertising creativity before and after the abolition of pre-screening. The results are these; Ad persons thought that ad creativity improved greatly, and use of foreign language and comparative ads were also increased. In the case of ad creativity, without distinction of occupation category, length of work experience, and gender, showed similar changes. But, in the case of use of foreign language, long work experience group(over 10years experience) felt the change bigger than short work experience group(less than 10 years) did. About ad ethics, ad persons perceived it was decreased after the abolition of pre-screening, but, the influence of pre-screening on ad ethics was non-significant. These research results are meaningful because that revealed the changes after the abolition of pre-screening, provided the clues to infer the influence of review, and also provided some useful considerations for other cases.

<i>Sargassum serratifolium</i> Extract Attenuates Interleukin-1β-Induced Oxidative Stress and Inflammatory Response in Chondrocytes by Suppressing the Activation of NF-κB, p38 MAPK, and PI3K/Akt

<P>Osteoarthritis (OA) is a degenerative joint disease that is characterized by irreversible articular cartilage destruction by inflammatory reaction. Among inflammatory stimuli, interleukin-1β (IL-1β) is known to play a crucial role in OA pathogenesis by stimulating several mediators that contribute to cartilage degradation. Recently, the marine brown alga <I>Sargassum serratifolium</I> has been reported to exhibit antioxidant and anti-inflammatory effects in microglial and human umbilical vein endothelial cell models using lipopolysaccharide and tumor necrosis factor-α, but its beneficial effects on OA have not been investigated. This study aimed to evaluate the anti-osteoarthritic effects of ethanol extract of <I>S. serratifolium</I> (EESS) in SW1353 human chondrocytes and, in parallel, primary rat articular chondrocytes. Our results showed that EESS effectively blocked the generation of reactive oxygen species in IL-1β-treated SW1353 and rat primary chondrocytes, indicating that EESS has a potent antioxidant activity. EESS also attenuated IL-1β-induced production of nitric oxide (NO) and prostaglandin E<SUB>2</SUB>, major inflammatory mediators in these cells, which was associated with the inhibition of inducible NO synthase and cyclooxygenase-2 expression. Moreover, EESS downregulated the level of gene expression of matrix metalloproteinase (MMP)-1, -3 and -13 in SW1353 chondrocytes treated with IL-1β, resulting in their extracellular secretion reduction. In addition, the IL-1β-induced activation of nuclear factor-kappa B (NF-κB) was restored by EESS. Furthermore, EESS reduced the activation of p38 mitogen-activated protein kinase (MAPK) and phosphatidylinositol-3-kinase (PI3K)/Akt signaling pathways upon IL-1β stimulation. These results indicate that EESS has the potential to exhibit antioxidant and anti-inflammatory effects through inactivation of the NF-κB, p38 MAPK, and PI3K/Akt signaling pathways. Collectively, these findings demonstrate that EESS may have the potential for chondroprotection, and extracts of <I>S. serratifolium</I> could potentially be used in the prevention and treatment of OA.</P>

목적: 평균수명의 증가에 따른 사회의 고령화와 식생활의 서구화 및 진단기법의 발전으로 우리나라 소화기관의 게실 빈도는 증가하는 추세이며 이에 따른 대장 게실의 임상양상 또한 후천적 영향에 의해 서구화될 것으로 생각된다. 이에 저자들은 대장 게실증을 진단받은 환자를 대상으로 대장 게실증에 영향을 미치는 후천적 인자를 알아보고자 하였다. 대상 및 방법: 2010년 5월부터 2012년 4월까지 인제대학교 서울백병원에서 시행한 대장내시경검사에서 게실이 관찰되었던 사람을 대상으로 하였으며, 설문을 통해 대상군의 나이, 체질량지수, 복부둘레, 운동량, 지방 섭취 정도, 흡연 및 음주의 정도를 조사하여 대장 게실의 임상양상과의 연관성을 알아 보았다. 결과: 연구 대상은 총 200명으로 나이는 54.9±11.9세(범위17-79세)였고 대장 게실증의 남녀비는 2.2:1이었다. 게실의 위치는 우측 대장이 83%였고 게실의 평균수는 4.07±3.9개였다. 게실 위치와 연관성을 보인 인자는 나이였는데 고령일 수록 좌측에 위치하였고(p=0.001), 게실의 수는 허리둘레와 유의한 연관성을 보였으며(partial correlation coefficient r`=0.143, p=0.047), 대장 게실염은 나이가 적을수록 증가하였다(p=0.002). 결론: 대장 게실의 위치는 고령일수록 좌측에 호발하였으며 게실 수는 복부비만과 연관성을 보였다. Background/Aims: The prevalence of colonic diverticulosis in Korea is increasing in conjunction with the adoption of western dietary pattern, extension of lifespan, and advances in diagnostic modalities. The clinical characteristics of colonic diverticulosis seem to be gradually becoming similar to those of Western societies. Therefore, factors associated with the clinical characteristics of colonic diverticulosis in Korea were investigated. Methods: The data of 200 patients diagnosed with colonic diverticulosis using colonoscopy between May 2010 and April 2012 at Inje University Seoul Paik Hospital (Seoul, Korea) were prospectively collected. Clinical parameters acquired through a questionnaire include age, body mass index, waist circumference, exercise, diet, smoking, drinking habits, etc. Correlation between these factors and the clinical features of diverticulosis were analyzed. Results: Mean age of the patients was 54.9±11.9 (range 17-79) years and male to female ratio was 2.2:1. Most diverticula were located on the right side of the colon (83%) and the mean number of diverticulum was 4.07±3.9. Factor associated with the location of diverticulum on the left side was age (p=0.001). There was a positive correlation between the waist circumference and the number of diverticulum (partial correlation coefficient r`=0.143, p=0.047). Diverticulitis occurred more frequently in younger patients than in older patients (p=0.002). Conclusions: Colonic diverticulosis in older patients is found more frequently on the left colon, and the number of diverticulosis is associated with central obesity.

Acute patellar dislocation is a painful, terrifying experience that always occurs suddenly. The recurrence is unfortunately common and each experience is just as painful to the patient. With each acute dislocation, additional intraarticular derangement occurs. Therefore the goals of treatments are not only to relieve acute pain by prompt reduction of the dislocation but also to remove any chondral or osteochondral fragments that may be present within the knee joint and to restore normal patellofemoral anatomy, thereby preventing recurrent dislocation and avoiding future patellar subluxation. To present the details of arthroscopic medial retinacular repair in acute patellar dislocation. we report 2 patients with treatment of acute patellar dislocation with osteochondral loose body.

The bone infection after hip arthroplasty which can bring a catastrophic results to the patient has been problem due to the difficulties in the diagnosis and treatment. To solve this problem, infectionspecific WBC scan has been developed. Recently "Tc-HMPAO(Technetium-99m hexamethylpropylene-amineoxime)-WBC scan was introduced and have been adopted for detection of infection. However the diagnostic value and possible problem have not been proved yet. The authors attempted to find out the diagnostic value and limitation of " Tc-HMPAO-WBC scan in the infection after hip arthroplasty. Twenty-five patients, who underwent " Tc-HMPAO-WBC scan from October 1994 to February 1997 in Asan Medical Center, were analysed. Through comparing the results of " Tc-HMPAO-WBC scan with operative, microbiologic, radiologic and clinical findings, we have reached the following conclusions. 1. ""Tc-HMPAO-WBC scan was very sensitive to the detection of bone infection after hip arthroplasty. 2. The delayed imaging decreased the false negative rate, but the problem of detection of subacute or chronic infection should be studied. 3. The false positive rate was relatively low, and when we combine Tc-MDP bone scan with Tc-HMPAO-WBC scan, probably the false positive rate will be decreased more than now. 4. Single Photon Emission Computed Tomography(SPECT) could help to localize the infection focus and detect the low activity of infection.
