Objective: To evaluate the usefulness of serum concentrations of macrophage migration inhibitory factor (MIF) of patients with ovarian cysts for differential diagnosis of endometrioama. Method: From Jan. 2003 to Dec. 2004, preoperative serum MIF levels were assessed in 28 women with endometrioma, 32 with benign epithelial tumor, 23 with functional and simple cysts, 22 with benign mature cystic teratoma, and 25 women without ovarian tumor as control. MIF levels were determined using an ELISA (Quantikine Human MIF immunoassay, R&D Systems, Inc., USA). Results: Mean MIF levels were higher in all groups with benign tumors than control (all p<0.01), but there was no significant difference between benign tumor groups (p=0.95). There was no significant correlation between MIF levels and tumor volume, body mass index (BMI) (p=0.635, 0.674 respectively) Serum MIF level had significant correlation with count of WBC and neutrophils (p=0.008, 0.024 respectively), but had no correlation with count of lymhocytes and monocytes (p=0.688, 0.294 respectively). Conclusions: This study showed a marked increase in MIF concentrations in the peripheral blood of patients with endometrioma, but there was no significant difference with other benign tumors. Serum MIF level had significant correlation with count of WBC and neutrophils. These suggest serum MIF level has no usefulness for differential diagnosis of endometrioma from other benign ovarian cysts.

The purpose of this study was to develop a faster analysis method of PCBs in transformer oil and to compare this to the Korean official method. The Korean official method is composed of 4 steps; alkaline digestion, sulfuric acid extraction, clean-up with silica-gel column, and concentration by nitrogen blowing. On the other hand, the proposed fast PCBs analysis method is composed of simpler steps; one-step column separation (Rapiana) and the following concentration by nitrogen blowing. Both methods were compared by analyzing same samples including CRMs. GC/ECD equipped with dual column was used for PCBs analysis. PCB-189 and PCB-209 were used as surrogates and TCMX (tetrachloroxylene) was used as internal standard. Surrogate recovery (75-120%) obtained by the proposed fast analysis method turned out to be better than that of the Korean official method (63-85%). The fast PCBs analysis method is faster than the Korean official method (3 hours vs 20 hours) and also can save labor and analysis cost.

본 연구는 3개 특정공동체에 대하여 미디어에서 정책적으로 의제설정(agenda setting)되었던 텍스트담론을 중심으로 의미작용(signification)의 기호학적(semiotics)분석이다. 연구대상의 자료는 잡지와 전문지, 신문 33개 매체에 게재된 칼럼(column), 특별기고, 시사평론 등 71개의 텍스트담론이다. 연구는 부가의미로 볼 수 있는 은유(metaphor)와 환유(metonymy), 그리고 이분적(binary oppositions)사고 전환( transposition)에 보다 관심을 둔다. 이런 함축적 부가의미는 여러 미디어를 통하여 대중 속으로 내파(imploded)되어 현실보다 더 실재적인 과실재성(hyperreality)으로 신화(myth)를 창출한다. 따라서 본 연구는 미디어가 정책적으로 만들어낸 텍스트담론을 기호학적 시각에서 해체와 분석할 수 있는 이론적 논리를 개발하고자 한다. 또한 기호학의 경계점에서 문화흐름이 정치, 사회, 그리고 경제 등 정책에 어떤 영향을 주는가를 연구할 수 있는 범위를 확장하는 데 있다. 결과적으로 본 연구에서 대상체(referent) 인 T'PALACE, I'PARK, STARCITY가 지시하는 객관적 외시적의미(denotation)는 기존 타 커뮤니티보다 '규모가 크고', '높은 고층이고', '주로 학력 높은 부자들이나 재벌들', 그리고 '연예인들이나 성공한 CEO들'이 거주한 것으로 알려진 외시적의미를 갖는다. 그리고 공동체의 대상체가 지시하는 주관적인 다의적 함축의미(connoation) '귀족커뮤니티', '초호판극치 공간', '양재천의 꽃', '그들만의 공간' 등 은유적 표현은 '대한민국 부 1번지', '벤치마킹대상', '고급주거형태 견본', '국내최고급아파트', '대한민국강남특별시', '1%의 욕망', 등과 같은 환유적 전환의 함축의미로 신화와 이데올로기를 창조하고 있다. 이런 이데올로기와 신화는 미디어를 통해 대중속으로 내파되어(imploded)어 타 지역에서 동일의 이름을 가진 공동체 커뮤니티로 재생산되어 소비(분양)되고 있다. 또한 경제, 문화가 정책이나 정치적으로 활용되어 '종부세', '부자감세', '1%의 부자감세' 등과 같은 정부규정이나 슬로건을 창조하고 있다. This study is the text discourse of agenda setting through media policy on the three communities. The materials of subjects are the 71 text discourses that appeared in the columns, the special manuscripts, and the comments on the contemporary topics in 33 media. The subjects focuses on the metaphor, metonymy, and binary transposition. This kind of connotation tends to be imploded into people through media, so that it produces hyperreality. This process produces the regulation and strengthens the reality through the circuit of culture. Thus this research tries to develop the theoretical foundation for analysing the text discourse produced by the media. Also it focuses on widening the research scope to study the effects that the circuit of culture provides on the politics, society, and economics. Therefore The first, the objective meanings(denotation)which the referents of the community as T'PALACE, I'PARK, and STARCITY are 'larger scale', 'high and skyscraper', 'the rich people and the plutocrats who have very high academic career' and ' the residence place for the famous stars and successful CEOs', etc. and the subjective meanings, connotations which the referents of the community are 'The first street' transposes '1%' 'their own space' into the characteristics of the wealth of Gangnam district or Korean wealth', the additional significations which the metaphors such as 'the noble community', 'the sample for the high -level residential space', and 'the greed of 1%'. Conclusion, The significations of the symbols became imploded into the population and circulated along with the cultural streams through the media. The referents are recreated and consumed among the other communities such as the named 'PALACE', 'I'PARK', 'STARCITY' in the other areas. This kind of ideology tends to create the myths such as 'the 1% rich people of Gangnam', 'the first street of Korean wealth', and create the regulation such as 'the compound taxes for the real-estates', 'the policy of reducing the taxes for the rich', 'the policy of reducing the taxes for the 1% of the rich'. Also these regulations make the politicians operate new policies and are being utilized as 'slogan' for the politicians.

김만기 ( Man Ki Kim ) 한국PR학회 2004 PR연구 Vol.8 No.2

Since Korea became a member of WTO, many agricultural products have been imported into country. As a consequence, local self-governing bodies have been developing many unique new agricultural brands, to compete with similar products imported from other countries. The purpose of this study is to review the present condition of agricultural brands, to point out the problems of the agricultural brand, and to provide progressive new methods of marketing for agricultural brand names. To achieve this purpose, this study deals with the comparisons of the agricultural brands, in connection with naming, identification, information, royalties, and associative image, as an intrinsic function of brand marketing. It also deals with communications, public relation strategies, and customer relations, as a derivative function of brand marketing. This study provides new methods of agricultural marketing strategies. The new methods are systematic, professional, and progressive. This study suggests that those who work in the field of agricultural production and agricultural delivery industries understand that their brands` name is important, and continued local government support is needed. This study shows these new methods of agricultural marketing strategies can make it possible for brands to have more valuable.

In this paper, we propose a describes how to detect a false iris image by inserting watermark into a iris image. The existing method, which inserts the watermark into the entire iris image to detect a fake iris, has a problem that can evade it by segmenting iris region of an iris image. The purpose of overcoming the problem, this paper proposes a new fake iris detection technique based on digital watermark. It first searches a central point of an iris image, divide the image into blocks with respect to the point. executes Discrete Cosine Transform, inserts watermark into the blocks, and then verifies an iris image using NC(Normalized Correlation). In the experiments, we confirm the robustness for attacks – crop and JPEG.
