This research was conducted to investigate the effect of essential oil (EO) from Artemisia Princeps Pampanini on quality of tomato during storage. EO was extracted by steam distillation and diluted by 1 and 2%. Total phenolic contents and antioxidative activities of EO were analyzed. Tomato was packaged corrugated box covered with polypropylene (PP) film containing EO (1 and 2%) and then stored at room temperature for 10 days. During storage, appearance, weight loss rate, soluble solid contents, pH and a (redness) value were measured for tomato. Total phenolic contents of EO increased in a dose-dependence. The DPPH and ABTS radical scavenging activities also showed a concentration-dependent increase. The weight loss rate was lowest using the film packaged in 1% EO. During the storage period, soluble solid contents and pH increased in all treatments. The a value increased regardless of EO concentration in films. Especially, tomato packaged with EO film showed a lower a value than non EO-packaged ones. This result suggests that application of EO to film is effective for tomato quality preservation.

The micro Vickers hardness and internal stress of Ni-Fe metal thin film synthesized by electrodeposition method at $25^{\circ}C$ were studied as a function of bath composition, and surface microstructure and atomic compositions of thin films were investigated by SEM and EDS. And the shape change of $200\;{\AA}$ Ni-Fe nanowires made using anodic aluminum oxide(AAO) templates by electrodeposition method were observed by SEM as a function of ultrasonic treatment time and bath composition. The Fe deposition contents on the substrate non-linearly increased with Fe ion concentration over total metal ion concentration. In case of low Fe contents film, the grain size is smaller and denser than high Fe contents deposited films, and the micro Vickers hardness increased with Fe contents of electrodeposited films. These results affected the shape change of nanowire after ultrasonic treatments.

The Korean films in the 1980s played an important role in impeding the interaction between the media and the audience. In terms of two mechanisms of money and power, the Korean films lost the function of publicity and were forced to disregard positive aspects of culture as a way of understanding society. As a mass medium, the film did not give people the space for critical thought and discussion on social reality. This study tries to discuss how Korean movies in the 1980s functioned as a bulwark of critical debate provided by the interaction between cultural texts and audiences through the notion of the public sphere. For Habermas, the public sphere provides a basis for critical analysis in order to reveal the relationship between media and economic and administrative power in a modern society.

This research is a study of the documentary film entitled "Korean War." My research focuses on the collective trauma and amnesia of the Korean War among the people of the U.S. in an effort to understand ongoing tensions between the U.S. and the two Koreas, both North and South. A study of the film also gives a way to read the hidden meaning of the film through deconstructing the film with Peircian semiotics, and scrutinizing its artistic choices of visual language. This study provides a review of the theory of trauma. It also gives insight into understanding the perceptions of the Korean War in the U.S.

This paper attempts to understand the reality of Netflix on the Korean film distribution market environment, and to verify the possibility of developing domestic content centered on independent films in the OTT market, led by Netflix. The research significance of finding the way for Korean diverse films and independent films that cannot be provided with investment and distribution opportunities in various Korean Wave contents will be studied, and the characteristics of Netflix in the Korean film market will be explored. Netflix disseminates Korean contents such as Korean movies and Korean dramas, contributes to the spread of the Korean Wave, and is re-adjusting the paradigm of the distribution market, raising issues that cause a virtuous cycle of profits, controversy over net usage fees, and flooding of Hollywood movies. Considering the nature of intercultural exchange, the interaction between independent film content, Netflix platform, audience, and global market will expand interactive communication opportunities. In other words, just as Netflix uses the Korean media market to make profits, Korea should also use Netflix to try to expand the global market of Korean film contents (K-Film)and maintain a cultural and economic reciprocal attitude.

Li-doped ZnO films were prepared on Corning 1737 glass substrate by an rf magnetron sputtering technique using ZnO targets with various $Li_2CO_3$ contents ranging from 0 to 10 mol%. The effects of Li doping on the crystallinity and electrical properties of ZnO films were studied for their SAW filter applications. The film resistivity largely increased without suppressing the c-axis orientation and crystallinity with a small addition of Li. Heat treatment of the film at 40$0^{\circ}C$ induced that the film resistivity, c-axis orientation and crystallinity slightly increased. However, heat treatment of the film at 50$0^{\circ}C$ resulted in much lower resistivity than that of as-deposited film due to the increase of electron concentration caused by the evaporationof Li atoms from the ZnO film. Large addition of Li into the ZnO film rather diminished the film resistivity and suppressed the c-axis growth. It was concluded that a small doping of Li into the ZnO film and heat treatment at 40$0^{\circ}C$ caused the film resistivity to be high enough for SAW filter applications without suppression of the c-axis orientation and crystallinity.

For better management of micronutrients in crop cultivation, the availability of micronutrients in the soils must be updated and evaluated as a first step. This study was conducted to investigate the distribution of micronutrients in soils of plastic film houses. Total 396 soil samples were collected from the plastic film houses of various crops in Yeongnam province (strawberry, 96; red pepper, 66; tomato, 74; oriental melon, 97; cucumber, 63). Total and available contents of B, Cu, Zn, Fe, and Mn in the soils were determined. Available B was extracted with hot water and available Cu, Zn, Fe, and Mn were extracted with 0.1 N HCl. Mean values of total contents of B, Cu, Zn, Fe, and Mn in the plastic film house soils were 25, 32, 74, 21,316, and $420mg\;kg^{-1}$, respectively. Total contents of micronutrients in the plastic film house soils were similar to those found in the open fields nearby, while they were different among the locations investigated. Mean contents extractable B, Cu, and Zn in the plastic film house soils were 2.1, 7.5, and $35mg\;kg^{-1}$, respectively. The contents of extractable B, Cu, and Zn in the plastic film house soils were higher than those found in the open fields nearby with exceptions of B in soils of strawberry and Cu in soils of red pepper and oriental melon. However, mean contents of extractable Fe and Mn in the plastic film house soils were 156 and $146mg\;kg^{-1}$, respectively, and the mean content of extractable Fe was much lower than that found in open fields nearby. The contents of extractable Zn, Fe, and Mn were higher than the sufficient levels for the crop requirements in most of the plastic film house soils investigated. Contents of extractable Cu in most soils of strawberry, tomato and cucumber cultivations were higher than the sufficient level. However, extractable Cu contents were below the sufficient level in about 30% of investigated soils of red pepper and oriental melon cultivation. Soils containing higher contents of extractable B than the sufficient level were relatively fewer in comparison to the other micronutrients.

Antioxidative polyethylene films for food packaging were experimentally prepared by fortification of TBHQ(tertiary butylhydroquinone) and dl-a-tocopherol at the weight ratio of 0.05, 0.2 and 0.5%, respectively and laminated with nylon. TBHQ and tocopherol contents in the PE/nylon film were analyzed and the antioxidative effects of film were investigated on the lipid oxidation of semi-dried squid during storage at 5℃ and l5℃. TBHQ contents of TAP 1(TBHQ 0.05%), TAP 2(TBHQ 0.2%) and TAP 3(0.5%) were 38, 146 and 365 mg/100g, respectively. Tocopherol contents of DAP l(tocopherol 0.05%), DAP 2(tocopherol 0.2%) and DAP 3(tocopherol 0.5%) were 33, 139 and 356 mg/l00g, respectively. TBA value and POV during storage of semi-drid squid were affected both by storage temperatures and packaging films. Lipid oxidation during storage was retarded by anti-oxidative films, as TBA value of TAP 3 and DAP 3 revealed about 50% of control after storage at 5℃ for 20 days and similer effects in POV were also observed.

W $O_{x}$-based semiconductor type thin film gas sensor was fabricated for the detection of N $O_{x}$ by reactive d.c. sputtering method. The relative oxidation state of the deposited W $O_{x}$ films was approximately compared by the calculation of the difference of the binding energy between Ols to W4 $f_{7}$2/ core level XPS spectra in the standard W $O_3$ powder of known composition. As the annealing temperature increased from 500 to 80$0^{\circ}C$, relative oxygen contents and grain size of the sputtered films were gradually increased. As the results of sensitivity ( $R_{gas}$/ $R_{air}$) measurements for the 5 ppm N $O_2$ gas, the sensitivity was 110 and the sensor showed recovery time as fast as 200 s. The other sensor properties were examined in terms of surface microstructure, annealing temperature, and relative oxygen contents. These results indicated that the W $O_3$ thin film with well controlled structure is a good candidate for monitoring and controlling of automobile exhaust.haust.t.t.t.
