The purpose of this study is to explore structural relationship between cognitive factors and emotional factors in predicting behavioral intention of duty-free users. This study conducted questionnaire survey on 246 users of duty-free shops and analyzed it by using structural equation. As the result of the study, attitude was significantly associated with both desire and behavioral intention. Subjective norm had a significant impact on desire, but had no significant imfact on behavioral intention. Whereas perceived behavioral control did not have a significant influence on desire and intention. Desire, which plays mediating role as a major variable in goal-directed behavioral model, turned out to not only have significant impact on behavioral intention but has the strongest effect as well. This study has its academic meaning in that it explored factors which have effect on decision-making process of duty-free users focusing on goal-oriented behavioral model, which is one of integrated psychological models. In practical terms, this study can be used as a basic material for corporations to establish goals in domestic duty-free shops.

Recently, starting with the permanent suspension of Gori 1 in Korea, the importance of the disposal of concrete structures in nuclear power plants has emerged, and environmental and safety are required to be proved accordingly. Safe radioactive waste disposal technology that immobilizes harmful radioactive elements, which are by-products of nuclear power, inside a solid matrix and recycling measures are needed to secure an efficient waste disposal space. This study was conducted to confirm whether recycled cement generated in the process of radioactive concrete treatment can be used as a solidifying material for radioactive waste treatment. In order to simulate the concrete exposed to radiation, aqueous solutions of Di-water, CsCl 1M, and CoCl₂ 1M were used as blending water at W/B 0.5. Tricalcium phosphate and Prussian blue were substituted with 5 wt.% based on the weight of recycled cement as a binder to improve solidification performance, and their hydration characteristic was analyzed.

수직배향 액정디스플레이의 시야각 향상을 위한 광대역 보상필름 개발

최유진(Yu Jin Choi),임영진(Young Jin Lim),정광운(Kwang Un Jeong),이승희(Seung Hee Lee) 한국고분자학회 2011 폴리머 Vol.35 No.4

수직배향 액정디스플레이의 시야각 향상을 위한 광대역 보상필름을 개발하였다. 상용화된 수직배향 액정디스플레이는 측면 시야각을 보상하는 위상차 필름을 필요로 한다. 일반적으로 triacetylcellulose(TAC)에 광학첨가제를 첨가한 후 제막연신을 통하여 수직배향 액정디스플레이용 위상차 필름을 제작하는데, 첨가되는 광학첨가제의 화학구조에 따라 필름의 위상차와 파장분산 특성이 달라진다. 본 연구에서는 첨가제에 따른 분극률 이방성을 양자역학적으로 계산하고, 선택된 중심 이성질체에 사이드 그룹을 치환시켜 파장별 분극률 이방성을 또한 계산하였다. 특히, 치환기가 methoxy와 propionate인 경우에 치환위치와 숫자에 따른 파장별 분극률 이방성을 비교하였다. 2개의 propionate 그룹이 meta 위치에 있을 경우가 파장분산 특성이 가장 완만한 것을 양자역학적 계산을 통하여 예측하였으며 이를 실험을 통해 증명하였다. 파장분산 특성이 완만하다는 것은 LCD 시야각 특성이 광원의 파장에 따라 덜 변한다는 의미이며, 현재 수준보다 우수한 화질을 구현할 수 있다. To expand the viewing angle of vertical alignment liquid crystal display(VA-LCD), a wide-band compensation film has been newly developed. VA-LCD needs a retardation film with improved oblique viewing property. The retardation film for VA-LCD has been fabricated by solvent casting and subsequent drawing triacetylcellulose (TAC) containing optical additives. Here, optical birefringence and wavelength dispersion of the retardation film strongly depend on the chemical structures of optical additives. Utilizing quantum mechanical computation, the polarizing anisotropy of retardation film was calculated with respect to additives. It is also realized that the wavelength dispersion of polarizing anisotropy depends on the type and location of substituent to the selected main isomer. When two propionates are substituted to the meta position of the selected main isomer, the wavelength dispersion of polarizing anisotropy shows the most gentle slop, which is well matched with the experimental results. The most gentle slop of wavelength dispersion means that the viewing angle characteristics of LCD are less influenced according to the wavelength of light source of LCD, and it`s possible to make better image quality than the present level.

Purpose: To evaluate the results of treatment according to the method of intravitreal injection of bevacizumab for macular edema due to branch retinal vein occlusion (BRVO). Methods: The clinical records of macular edema patients were analyzed retrospectively for a total of 62 eyes of 62 patients who were injected with bevacizumab into the vitreous as the first treatment for BRVO. Best-corrected visual acuity (BCVA), the findings of spectral-domain optical coherence tomography before and after injection, and prognosis-related factors were evaluated for 21 eyes that received the initial three monthly loading treatments and the 41 eyes that did not. Results: Significant improvement in BCVA was observed in the group having received the initial three injections compared with the group who did not receive the injections at 3, 6, and 12 months (p = 0.025, p = 0.019, and p = 0.008, respectively). The central macular thickness (CMT) showed greater improvement in the initial three injections group than the group without at 6 months (p = 0.034). Multivariate regression showed that the duration from the onset, the three loadings, BCVA, disorganization of the retinal inner layer (DRIL), and choroidal thickness were predictors related to visual gain (p = 0.044, p = 0.047, p = 0.004, p = 0.045, and p = 0.034, respectively). Age, three loadings, BCVA, and DRIL were predictors related to final visual acuity (p = 0.045, p = 0.046, p = 0.002, and p = 0.034, respectively). Duration from the onset, CMT, and choroidal thickness were predictors related to CMT improvement (p = 0.042, p = 0.009, and p = 0.015, respectively). Conclusions: In macular edema of BRVO, the initial three monthly intravitreal injections of bevacizumab provided superior treatment outcomes regarding short-term functional and anatomical improvements and long-term functional improvement, compared with methods that did not treat with the initial three monthly injections.

서울의 대기 중 이산화질소(NO2) 저감 둔화 원인 분석 및 대응방안

NO2 concentration in Seoul has not been improved in spite of implementing various NOx emission control policies. In this study, the reasons for the slow reduction of NO2 concentration were investigated through comparing control measures of developed cities, both successfully managing NO2 and poorly managing NO2, with Seoul`s. Also, NO2 characteristics in Seoul was analyzed in prospective of primary NO2 emission issue, which has been actively discussed in Europe, The most effective policy for NO2 control in California and Tokyo, where NO2 has been improved consistently, was to introduce much stricter NOx emission standards for diesel vehicles than in London and Seoul. Introducing strict emission standards results in a low penetration rate of diesel vehicles known as larger NOx emitters than gasoline vehicles, which prevents fundamentally NOx emissions, In addition, Tokyo controlled both NOx and PM by implementing ``Vehicle NOx PM law`` in 2001, and a policy discouraging polluted diesel vehicles from being driven in Tokyo and surrounding area in 2003. Increasing proportion of primary NO2 emission, originating from modern diesel-technology vehicles with DPF and DOC for the purpose of reducing PM emissions, has been observed and considered an importance reason for the slower reduction of NO2 concentration in urban cities of Europe with high penetration rates of diesel vehicles. The result of primary NO2 emission analysis from 2000 to 2010 for Seoul shows that the proportion of primary NO2 in the vehicular NOx emission is in a range of 11~32% for monthly averages and 15~21% for yearly averages. This proportion of primary NO2 emission is high enough to be related to the slower reduction of NO2 concentration in Seoul as for many cities in Europe. Therefore, we conclude that one important reason for the slower reduction of NO2 concentration in Seoul is the increasing penetration of diesel vehicles with the primary NO2 emission issue due to the relaxed NOx emission standards for diesel vehicles. In order to control NO2 concentration in Seoul, it is necessary to decrease the primary NO2 emissions as well as total NOx emissions. Considering diesel vehicles major emission sources of both NOx and PM, policies reducing all of PM, NOx, and primary NO2 emissions should be preferentially implemented. With this principle in mind, several policy suggestions are made. Also, laws and regulations related to vehicle emission standard, vehicle emission inspection and DPF certification should be revised in advance.
