Interior design generally falls behind to architecture in its concept of conservational value as interior designs are more to the simple style or trend. Therefore, This study aims how the society and the major events in the 1960's and individual and group desires are portrayed in movies through the eyes of movie directors, and further how the concept of spaces and the features of the spaces are displayed. First, This paper analyzes the movies in the 1960's, especially the expressionism and psychological zeitgeist in "The Housemaid" directed by Kim Ki-Young that can be logically analyzed, following the signs in the movie. Secondly, It analyzes the images captured the scenes that best describe the underlying theme of the movie, revealing the features of the different spaces for different scenes. Moreover, It analyzes the correlation of the change in value, desire, and space of the time in the 1960's to see the feature of the spaces in the 1960 are represented in the movie. In conclusion, the realistic expressionism movie of Kim Ki-young's 'Housemaid' showing the everyday life of a family against the background of industrial capitalism reveals the intimate desire of the time with the director's perspective on the history. With Mise-en-Sc$\grave{e}$ne, we can understand the space structure of the time, the view on space structure and further the effect of modernization project on urban residential area.

Flexible strain sensors, as the core member of the family of smart electronic devices, along with reasonable sensing range and sensitivity plus low cost, have rose a huge consumer market and also immense interests in fundamental studies and technological applications, especially in the field of biomimetic robots movement detection and human health condition monitoring. In this paper, we propose a new flexible strain sensor based on thick CVD graphene film and its low-cost fabrication strategy by using the commercial adhesive tape as flexible substrate. The tensile tests in a strain range of ~30% were implemented, and a gage factor of 30 was achieved under high strain condition. The optical microscopic observation with different strains showed the evolution of cracks in graphene film. Together with commonly used platelet overlap theory and percolation network theory for sensor resistance modeling, we established an overlap destructive resistance model to analyze the sensing mechanism of our devices, which fitted the experimental data very well. The finding of difference of fitting parameters in small and large strain ranges revealed the multiple stage feature of graphene crack evolution. The resistance fallback phenomenon due to the viscoelasticity of flexible substrate was analyzed. Our flexible strain sensor with low cost and simple fabrication process exhibits great potential for commercial applications.

영화 <먼지 속으로 사라지다> 는 중국의 서북 지역 농촌 현실을 핍진하게 반영했다고 평가된다. 영화에서는 비록 농민 특유의 성실함과 순박한 사랑도 담았지만 많은 문제점도 제기하였다. 구체적으로 제기한 문제는 다음과 같다. 첫째, 결혼 시 자신의 의사를 제대로 피력하지 못하는 중국 농촌 청년들을 고발하였다. 이는 장기간 제대로 된 교육, 의료, 복지 혜택을 받지 못한 원인이 크다고 할 수 있다. 둘째, 현실과 괴리된 농촌 주택 정책을 비판하였다. 지역특성과 농민의 상황을 고려하지 않고 일방적으로 도시의 아파트를 제공해주는 것은 오히려 역효과가 날 수 있다고 경고하고 있다. 영화에서 주인공은 가족과 같이 생각하고 돌보는 가축 등을 버려두고 자신만 거주지를 아파트로 옮겨 생활하지 않는다. 셋째, 농촌에 만연된 물질만능주의를 비판하였다. 모든 것을 돈으로 해결하려고 하고 심지어 정부의 주택 보상금을 받기 위해서 인간을 존중하지 않는 현상을 비판하였다. 이러한 의미로 볼 때, 진정한 중국 삼농 문제의 해결을 위해서는 거시적으로 추진되는 정책과 일부 낙후된 농촌 지역도 아우를 수 있는 미시적인 정책도 함께 실시되어야 한다.

Experimental investigations on heat and mass transfer characteristics in a vertical tube absorber have been carried out. Three different copper tubes with a length of 1.5m have been tested using LiBr solution and LiBr-$CaCl_2$ solution. The effects of solution flow rate, cooling water temperature, solution inlet temperature and evaporation temperature have been investigated in detail. It is found that heat transfer coefficient increases gradually with the increase of solution flow rate, but decreases rapidly for the flow rates less than 0.02kg/ms. The grooved tube generally shows better heat transfer performances than the smooth tube. LiBr solution shows almost no absorption capability for the cooling water temperatures over $40^{\circ}C$. LiBr-$CaCl_2$ gives less decreasing rate in absorption capability at these temperatures and the heat transfer coefficient becomes less dependent on the types of tubes in use. Considering heat and mass transfer rates, LiBr-$CaCl_2$ solution is found to be more suitable than LiBr solution for air cooled absorber, which operates at higher temperature than water cooled absorber.

Dielectric polymer films produced from benzocyclobutene (BCB) formulations (CYCLOTENE＊ family resins) are known to possess many desirable properties for microelectronic applications; for example, low dielectric constant and dissipation factor, low moisture absorption, rapid curing on hot plate without reaction by-products, minimum shrinkage in curing process, and no Cu migration issues. Recently, BCB-based products for thick film applications have been developed, which exhibited excellent dissipation factor and dielectric constant well into the GHz range, 0.002 and 2.50, respectively. Derived from these properties, the applications are developed in: bumping/wafer level packaging, Ga/As chip ILD, optical waveguide, flat panel display, and lately in BCB-coated Cu foil for build-up board. In this paper, we review the relevant properties of BCB, then the application areas in bumping/wafer level packaging and BCB-coated Cu foil for build-up board.

A surface plasmon resonance (SPR) sensing system, which belonged to a family of thin film refractometry-based sensors, was fabricated to measure the alcohol contents in alcoholic beverages. In this study, a SPR owe was obtained by a photodiode array with 128 pixels and transformed into a refractive index which was calculated by means of the first moment of values below a baseline of 0.85. When the sensing system was applied to Soju, Cheonju, Igwaduju and Tacju highly linear relationships between the refractive index by SPR and the contents of alcohol were obtained. That is, the coefficients of determination in their linear models were 0.992, 0.933, 0.918 and 0.954, respectively. Meanwhile, the effect of sample preparations on the accuracy of measurement was analyzed. As for Soju and Tacju, the best calibration equations were obtained when no sample preparation was applied. The best calibration models for measurement of Cheonju and Igwaduju were obtained through the samples filtered by $C_{18}$ disks.

The objective of this study was to investigate the physicochemical and microbiological characteristics of round of Hanwoo by vacuum packaging film materials, polyvinylidene chloride (PVDC) and ethylene vinyl alcohol (EVOH). The packaged beef samples were stored in refrigerated conditions (2±1℃) for 12 weeks. Physicochemical analysis with pH, surface color, thiobarbituric acid reactive substances (TBARS) values, and volatile basic nitrogen (VBN) values and microbiological analysis with aerobic plate count (APC) and metagenomic analysis of packaged beef samples were performed. The pH and surface color did not change substantially during the 12 weeks and EVOH-packaged beef tended to be lower than those of PVDC-packaged beef. PVDC- and EVOH-packaged samples showed low TBARS and VBN values below standard limits. APC did not exceed 7 Log CFU/g for both samples during storage. In metagenomic analysis, Firmicutes and Lactobacillaceae were dominant phylum and family of the PVDC- and EVOH-packaged beef. In both packaged samples, Dellaglioa algida was the dominant species during storage, with the notable difference being the presence of Lactococcus piscium. Therefore, this study provided the information on the quality of vacuum-packaged beef according to different vacuum films for long-term refrigerated storage.
