The purpose of this study is to examine the relationship between anti-Korean media and behavior. This study analyzed anti-Korean books published in Japan from 2000 to 2016. This study also analyses a survey conducted by those who have read that publication. According to the result, over half of the anti-Korea books published after 2010 and related to politics, history, and society of Korea. According to a result of the survey, people mainly get anti-Korean information from the Internet. Anti-Korean books affect to the anti-Korean information behavior not directly. In conclusion, while anti-Korean books affect anti-Korean behavior, it depends on the type of media.

The aim of this study was to develop a model that could be used in the design of modified atmosphere packaging (MAP) for Mandarin oranges. Respiratory data at 5, 10, 20$^{\circ}C$ for mandarin oranges were gathered and altered for create useful respiration model. The maximum rate of oxygen uptake increased with increasing temperature. The packaging materials were conventional low density polyethylene and polypropylene with anti-fog, and anti-fungi treatments, and thickness was 30 $\mu\textrm{m}$ and 50 $\mu\textrm{m}$. Permeability tests were performed to find their oxygen, carbon dioxide, water vapor transmission rate as increases in temperature. Test results were then converted to logarithm format for MAP modeling. Optimum gas composition in the package system for fruits were set according to literature and upper or lower limits of oxygen and dioxide established. To predict gas composition at certain storage time, weight of fruits, film thickness, film type, and other variables, respiration rate was studied at various storage conditions. The validity of the model was tested experimentally by observing actual atmospheric changes inside packages. It is concluded that the strategy developed is of use in designing dynamic gas exchange MAP systems, and also has potential uses in similar agricultural products.

This paper deals with the clay-bonded silicon carbide refractory saggars in terms of its oxidation resistance. Oxidation is one of the major causes of failure in silicon carbide refractory saggars during its services. Various anti-oxidation additives are coated on or added into silicon carbide refractories and their effects are studied while other conditions are equal. Several conclusions can be derived for optimum anti-oxidation additive as: 1. The additive should wet each silicon carbide grain completely during its firing. 2. The additive should have high viscosity at temperatures around $1, 350^{\circ}C$ where most silicon carbide refractory saggars are being used. 3. The additive should have ability to absorb or desorb oxygen depending on the local atmosphere inside of saggar during it service. 4. The addition should be kept as minimum as possible to prevent any "sweating" or "bloating" phenomena.ing" phenomena.mena.

The aim of this study was to develop a model that could be used in the design of modified atmosphere packaging (MAP) for peaches. Respiratory data at 5, 10, $20^{\circ}C$ for peaches were gathered and altered for create useful respiration model. Packaging materials were conventional low density polyethylene and polypropylene with anti-fog, and anti-fungi treatments, and thickness was $30{\mu}m$ and $50{\mu}m$ each. Permeability tests were performed to find their oxygen, carbon dioxide, water vapor transmission rate as increases in temperature. Test results were then converted to logarithm format for MAP modeling. The maximum rate of oxygen uptake increased with increasing temperature. Optimum gas composition in the package system for fruits were set according to literature and upper or lower limits of oxygen and dioxide established. To predict gas composition at certain storage time, weight of fruits, film thickness, film type, and other variables, respiration rate was studied at various storage conditions. The results of tests were used to calculate Cameron's model and converted to a cubic estimation equation. The validity of the model was tested experimentally by observing actual atmospheric changes inside packages. This result of study may be useful for designing dynamic gas exchange MAP systems for similar agricultural products.

동아일보는 해방 직후 시기에 친일파 지주들이 주축이 되어 설립한 한국민주당(한민당)의 기관지 역할을 하면서 왜곡보도로써 신탁통치 반대운동을 선동하여 여론전의 주도권을 장악하려 했다. 이는 미 국무성의 방침과 달리 신탁통치를 반대했던 미군정 당국의 견해를 대변하는 동시에 즉시독립을 갈망하는 민중의 정서를 이용하여 친일파 집단의 정체성을 불식시키기 위한 것이었다. 이를 위해 모스크바 3상회의의 결정을 왜곡하면서 반탁=반공=반소의 분위기를 조장했다. 이것은 과오에 의한 오보가 아닌 의도적인 허위.왜곡보도였다. 그 결과 반탁=반소=반공=애국, 친탁=친소=용공=매국의 공식이 성립되었다. 친일파들이 애국자로 둔갑하고, 반대로 3상회의의 결정을 수용하여 민주정부 수립을 추진한 사람들은 독립을 원하지 않는 매국노로 매도되었다. 이로써 토지개혁과 친일파 청산의 과제는 실종되었다. 그것을 바랐던 민중들도 반탁선동에 매몰되어 현안의 과제를 잊어버린 것이다. 그 분위기에서 친일파들은 미군정의 도움을 받아 단독정부 수립에 박차를 가함으로써 정국의 주도권을 완전하게 장악하였다. 친일파들이 한국사회의 주류가 되어 새 역사의 출발을 왜곡시켜 놓은 것이다. 나치독일에 협력했던 지식인들을 철저하게 숙청함으로써 새 나라의 기초를 튼튼하게 놓은 프랑스와 대비되는 대목이다. 동아일보는 태도는, 역사적으로 정치적 격변기에 나타나는 정론지(政論紙)의 전형을 보여주는 것이었다. 객관성과 중립성, 불편부당을 표방하며 시장에서의 경쟁을 통해 독자를 확보하려 했던 대중지(大衆紙)가 출현하기 직전, 정파적 견해를 대변하면서 정치적 목적의 선전과 선동을 일삼던 정치신문의 모습인 것이다.

In this study, it has been tried to make the single Mo-Cu alloying targets with the Cu showing the best surface hardness that was determined by investigation on the coatings with the double target process. The single alloying targets were prepared by powder metallurgy methods such as mechanical alloying and spark plasma sintering. The nanocomposite coatings were prepared by reactive magnetron sputtering process with the single alloying targets in $Ar+N_2$ atmosphere. The microstructure changes of the Mo-Cu-N coatings with diverse Cu contents were investigated by using XRD, SEM and EDS. The mechanical properties of the coatings were evaluated by using nano-indentor, scratch test, and ball on disc methods. Especially, the coated samples were tested by using various lubricating oil to compare the property of anti wear-resistance. In this study, the nano-composite MoN-Cu coatings prepared using an alloying target was eventually compared with the coatings from the multiple targets.

This paper investigates the effects of coating such as Invar (Fe-36% Ni), Fe-Ni Alloys and $WO_3$ on the doming property of aluminum killed (AK) shadow masks, which may be used for flat CPTs. Invar and Fe-Ni Alloys are deposited on AK shadow mask in plasma atmosphere and annealed. $WO_3$ is screen-printed on the deposited layer. The coating is observed to cause a decrease in the doming property of the shadow masks due to their lower thermal expansion coefficients and anti-doming properties.

In order to clarify the impact of anti-heat insulation pavement on the thermal structure of atmospheric boundary layer, field experiments and numerical simulations were carried out. Field experiment with various pavements were also conducted for 24 hours from 09LST 19 June 2007. And numerical experiment mainly focused on the impact of albedo variation, which is strongly associated with thermal characteristics of insulated pavement materials, on the temporal variation of planterly boundary layer. Numerical model used in this study is one dimension model with Planterly Boundary Layer developed by Oregon State University (OSUPBL). Because anti-heat insulation pavement material shows higher albedo value, not only maximum surface temperature but also maximum surface air temperature on anti-heat insulation pavement is lower than that on asphalt. The maximum value of surface temperature only reach on $49.5^{\circ}C$. As results of numerical simulations, surface sensible heat flux and the height of mixing layer are also influenced by the values of albedo. Therefore the characteristics of urban surface material and its impact on atmosphere should be clarified before the urban planning including improvement of urban heat environment and air quality.
