        네이티브 광고의 브랜드 및 제품 노출이 수용자의 광고 인지와 태도, 공유 의도에 미치는 영향

        이수범(Lee, Soo?Bum),송민호(Song, Min?Ho),문원기(Moon, Won?Ki),신명희(Shin, Myoung?Hee) 한국광고홍보학회 2016 광고연구 Vol.0 No.111

        본 연구는 60명을 대상으로 아이트래킹과 실험연구를 병행하여 네이티브 광고의 효과를 파악하기 위해 네이티브 광고에 대한 인지, 수용자 태도, 공유 의도를 검증하였다. 구체적으로 네이티브 광고를 콘텐츠와 브랜드 및 제품의 노출 형태(직접 노출/간접 노출)를 고려하여 두 유형의 네이티브 광고에 대한 시각적 주의가 피험자들의 광고 인지에 미치는 영향을 비교하였다. 또한 두 유형의 네이티브 광고에 대한 태도(콘텐츠 태도, 브랜드 태도, 공유 의도)를 측정하여 각 유형에 따른 차이를 비교하였다. 분석결과, 직접 노출 형태의 네이티브 광고의 구성 요소 중 콘텐츠 본문에 브랜드 관련 문구를 포함하였을 때 피험자들의 광고 인지에 긍정적인 영향을 미치는 것으로 나타났다. 또한 각 노출 유형별 콘텐츠 태도의 차이는 유의미하지 않았으나, 직접 노출일 때 브랜드 태도가 더 호의적인 것으로 나타났다. 마지막으로 직접 노출일 때 네이티브 광고의 공유 의도는 상대적으로 높게 나타났다. 이러한 결과를 종합하여 네이티브 광고 제작을 위한 실무적 제언을 담았다. This study explored the effects of native advertising on readers’ recognition, attitude, and sharing intention. This study used both quasiᐨexperiment and eyeᐨtracking for 60 participants to analyze advertising effectiveness (Attitudes toward contents/brands, and sharing intention) of two types native advertisements such as brand exposure (direct/indirect). According to the result of this study, direct exposure type ads had a high advertisement recognition that included brand wording in ad contents. In addition, there was no significant difference of attitudes toward contents among each ad types but direct exposure type ads had more favorable brand attitude than indirect type ads. Finally, this study also showed that the sharing intention of direct exposure type ads were higher than indirect type ads. Based on the findings, this study provided a practical implication for the production of native advertising.

        치과용 소와열구 전색제의 조성 용출에 관한 실험적 연구

        문현정,임범순,김철위 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.3

        From the recent study, it has raised controversy and concern about an estrogenic chemical, bisphenol-A, which was released from resin-based dental pit and fissure sealants. The purpose of this study was to identify and quantify bisphenol-A and other key leachable components that might be released from dental pit and fissure sealants. Five commercially available light-cured resin-based pit and fissure sealants were studied (CON, PEI, ELI, FSF, and TFI). Specimens were prepared from approximately 50㎕ of each pit and fissure sealants. After curing, specimens were weighed and immersed in two different solution (deionized water and 99.99% ethyl alcohol) for 5 hrs. solutions were analyzed by using High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Mass Spectroscopy (MS), and Ultraviolet Spectrophotometer (US) to detect various leachable components (bisphenol-A ; BPA, triethyleneglycol dimethacrylate ; TEGDMA, bis-glycidyl dimethacrylate ; Bis-GMA). There specimens of each sealant were tested. From the experiment, the following results were obtained : In deionized water, peak with retention time of 2.70 min was identified as TEGDMA and the amount of TEGDMA elution from specimens showed statistically significant difference (p<0.05). In ethyl alcohol, peaks with retention times of 2.70 and 6.04 (4.80) min were identified as TEGDMA and Bis-GMA (UDMA), respectively. TEGDMA eluted from CON, PIF, and ELI showed no statistically significant difference (p>0.05). Also, Bis-GMA eluted from CON, ELI, and FSF showed no statistically significant difference(p>0.05). However bisphenol-A was detected at PIT specimen in ethyl alcohol (retention time : 2.51 min in HPLC and 8.02 min in GC-Mass.). The monomers of pit and fissure sealants were leached within a range of 0.04∼1.94 % of the original weight of the cured sealant for five hours.

        중합 및 미중합 소와열구 전색제의 잔류 단량체 용출에 관한 연구

        문현정,임범순,김철위 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.3

        Triethyleneglycol dimethacrylate(TEGDMA), Bis-glycidyl dimethacrylate(Bis-GMA), and Urethane dimethacrylate(UDMA) are components of dental resin-based pit & fissure sealants which may be released and enter the body via skin, dentin and pulp. A recent study reported that hormone-mimicking compound, Bisphenol-A leached into saliva from dental pit & fissure sealants. The purpose of this study was to identify and quantify Bisphenol-A and other leachable components that might be released from polymerized and unpolymerized dental pit & fissure sealants. Seven commercially available light-cured resin-based pit and fissure sealants as the experimental group(Concise, Pit & Fissure sealant, Elite, Fissurit F, Teethmate F-1, Ultraseal XT Plus and Helioseal) and one composite resin (Z100) as the control group were studied. Specimens were polymerized by using a 1 mm (thickness) x 0.5 mm (diameter) acrylic mold which were weighed and immersed in 99.99% ethyl alcohol for 4 min, 2 and 12 hrs., 3 and 7 days. Solutions were analyzed by using High-Performance Liquid Chromatography(HPLC) to detect various leachable components. Three specimens of each sealants were tested. From the experiment, the following results were obtained : Specimen peaks with retention times of 2.28, 3.37, 6.18 and 7.39 min were identified as BPA, TEGDMA, UDMA, and Bis-GMA respectively. BPA was not detected in eluates from unpolymerized specimens(CON, ELI, HEL, Z100). PFS and ELI leached significantly more BPA than other specimens did(p<0.05). Generally, the quantity of TEGDMA leached as a function of aging periods showed no statistically significant difference(p>0.05), but in TFI and UXP group, they showed statistically significant difference after 7 days(p<0.05). The amount of Bis-GMA and UDMA elution after 3 days showed statistically significant difference(p<0.05). The monomers(BPA, TEGDMA, Bis-GMA, and UDMA) of pit and fissure sealants were leached within a range of 0.0023∼2.94% of the original weight of the sealants cured for 4 min, 2 and 12 hours, 3 and 7 days.

      • HBsAg 양성혈청에서의 HBeAg 및 anti-HBe 양성율과 ALT와의 관계 고찰

        문희주,윤기은,박정오,배형준,최범열 서울보건대학 1996 서울보건대학 부설 한국보건과학연구소 논문집 Vol.3 No.1

        The authors investigated HBeAg and anti-HBe in 1,000 cases(male 941, female 59) of HBsAg positive among the 225,512 blood donors in Seoul Nambu Blood Center in 1994. HBeAg and anti-HBe was detected by the method Enzyme Immunoassy. The results obtained were as follows ; 1. HBeAg and anti-HBe positive rates were detected 498 cases(49.8%) and 445 cases(44.5%) respectively among 1,000 cases HBsAg positive blood donors. 2. In HBsAg positive carriers, HBeAg positive rates were not significantly different between anti-HBe positive rates, but in sex were significantly different between HBeAg positive rates and anti-HBe positive rates. 3. HBeAg positive 498 cases were analyzed with age and it was found percentages of positive rates were 63.6% in 1st decade, 53.7% in 2nd decade, 20.6% in 3rd decade, 19.6% in 4th decade and 8.3% in over 5th decade, but anti-HBe positive 447 cases were 32.4% in 1st decade, 40.5% in 2nd decade, 69.2% in 3rd decade, 78.3% in 4th decade and 91. 7% in above 5th decade. 4. HBeAg positive rate decreased stepwise with age, while anti-HBe positive rate increased stepwise with age. 5. ALT abnormal cases in the HBeAg positive donors were higher than normal cases, but ALT normal cases in the anit-HBe positive donors were higher than abnormal cases.

        구강조건과 유사용액에서 치과용 소와열구 전색제의 잔류 단량체 용출

        문현정,이용근,임범순,김철위 대한치과기재학회 2000 대한치과재료학회지 Vol.27 No.1

        The estrogenic effect of Bisphenol A (BPA) was targeted because BPA can be present as an impurity in resins (Bis-GMA), or as a degradation product from other resins. 75% ethanol was used as a food-simulating liquids, similar liquid as oral environment, and solubility parameter of which matches that of resin. The purpose of this study was to identify and quantify BPA, TEGDMA, UDMA, Bis-GMA, and degradation product of Bis-GMA that might be released from seven resin-based pit and fissure sealants (CON ; Concise, PFS ; Pit & Fissure Sealant, ELT ; Elite, FSF ; Fissurit F, TMF ; Teethmate F1, UXF ; Ultraseal XT Plus, and HEL ; Helioseal). Specimens were embeded in 1 mm (T) x 5 mm (D) molds then cured and were immersed in 75% ethanol (EH) and artificial saliva (AS) for 1, 7, 14, 21, and 28 days. The extracts were analyzed by HPLC. All the components except BPA were leached highly at the initial stage, so the amount of component leached was not linear with the immersion time. In AS, only TEGDMA was leached. There were significant differences in the amount of eluted TEGDMA depending on the solution (p<0.05) in CON, PFS and ELI group (p<0.05). The amount of eluted BPA was various depending in the sealant (0.023∼2.790 ㎍/㎎). TEGDMA was leached highly from ELI, CON, and HEL in both EH and AS. Bis-GMA was leached from all the sealants, whereas UDMA was leached only from PFS, ELI, FSF, and UXP. The detected amount of BPA and the content of Bis-GMA was not correlated (p>0.05). Bis-GMA did not seem to be decomposed to BPA during the 28 days immersion period. EH penetrates the matrix of pit & fissure sealant, which has been shown to maximize the elution of resin components.

      • 고온가스냉각로(HTGR) 열전달 연구를 위한 상사실험 방법론 개발

        문덕원,고상혁,정범진 제주대학교 공과대학 첨단기술연구소 2005 尖端技術硏究所論文集 Vol.16 No.2

        Increasing interests on hydrogen, as a future alternative energy source, have led activities concerning the production, transportation, and use of hydrogen. As an activity to produce hydrogen using the nuclear heat, the development of HTGR(High Temperature Gas-cooled Reactor) are in progress. The gas phase coolant in the HTGR results in the coupling of buoyancy effect and increased radiation effect to most of heat transfer phenomena. In order to overcome those difficulties in the heat transfer study of gas phase coolant, an analogy experiment methodology was developed using analogy concept between heat transfer and mass transfer. The electroplating system with the limiting current technique is adopted to simulate heat transfer systems. Two typical heat transfer problems of Poiseuille flow and laminar and turbulent natural convections with well-known heat transfer correlations, were simulated. The test results show close agreements between heat transfer and mass transfer, which is encouraging indication of the validity of the analogy experiment methodology.

      • 크랙幅이 壓縮破壞强度에 미치는 影響

        文秉秀,黃秀喆,吳範錫,趙鎭境 충북대학교 산업과학기술연구소 2002 산업과학기술연구 논문집 Vol.16 No.1

        Under the compressive loads, tensile stress fields are possibly induced according to the boundary condition of compressed body. At the crack tip, the possibility of occurance of tensile stress fields are strong even under the compressive loads. In this paper, the fracturing behavior of brittle materials containing crack are investigated and the compressive strength affected by crack clearance are inspected theoretically and experimentally. Upon the theoretical and experimental results, it is found that compressive strength is decreased as the crack clearance is increased.

        콤포짓트 레진의 중합체계에 따른 중합률 및 잔류단량체 유출

        문현정,임범순,이용근,송재경,김철위 대한치과기재학회 2001 대한치과재료학회지 Vol.28 No.2

        Newly developed curing units for the dental composite resins are claimed to result in optimum properties and short curing time. The purpose of this study was to detemine the curing effectiveness of the curing units, and to evaluate the relationship between the degree of polymerization and leachability of residual monomer. Three composite resins were tested (Z100; z100, Herculite XRV; HX, Heliomolar; HM). Disk specimens of 2 mm in thickness and 6 mm in diameter were cured with a plasma arc [Apollo 95E; at 1370 mW/㎠, for 5 sec.(A5), 10 sec.(A10), 15sec(A15)], halogen lamp [VIP; at 500 mW/㎠, for 13 sec.(V13), 26 sec.(V26), 40 sec.(V40)] and custom made light emitting diode [LED; at 500 mW/㎠, for 13 sec.(L13), 26 sec.(L26), 40 sec.(L40)]. Specimens were immersed in 75% ethanol for 7 days. Eluates of the composites were analyzed by a high-performance liquid chromatography, and the degree of polymerization of composites were determined by a Fourier transform infrared spectroscopy. To obtain the sufficient curing by a plasma arc, the curing time should be longer than 10 sec. When the same light energy was irradiated, LED showed similar curing performance to halogen lamp. The light energy and the degree of polymerization was not correlated (p>0.05), but the light energy and the leachability of residual monomer was correlated (p<0.05). The leachability of residual monomer (TEGDMA+BisGMA) depended on the degree of polymerization.

      • 시계열 매칭 기반의 윤곽선 이미지 매칭 시스템 설계 및 구현

        김범수,문양세,김진호 강원대학교 정보통신연구소 2008 정보통신논문지 Vol.12 No.-

        In this paper we exploit time-series matching for boundary image matching. The motivation is based on that images can be converted to time-series. Thus, we implement a boundary image matching system using time-series matching techniques. We use an index-based matching method that efficiently performs boundary image matching. We implement our boundary matching system as a client-server model. Experimental results show that our index-based method outperforms the sequential scan by one to three orders of magnitude. Our system is practically implemented for image matching through the appropriate techniques in the time-series domain, and we thus believe that our approach can be widely used in image matching areas.
