In recent years, the Korean realistic theme of the film momentum gradually rising. Realistic films do not stick to the business and market, and do not simply cater to the audience's needs for watching movies. They reflect social violence and cruel reality, allowing the audience to observe the structural contradictions in reality and think about the direction when watching movies. At the recent cannes film festival, "parasite" won the top prize palm in cannes by an overwhelming margin, with the highest score of 3.3 issues. Although this film is positioned as a thriller with comedy elements, it presents the opposite life images of Korean classes to the audience in a parasitic way, which not only expands the possibility and artistry of realistic film aesthetics, but also enhances the appreciation of the film and gives play to its own aesthetic value. Focusing on the technical and literary nature of the film, and having a high degree of attention to real life, it is an excellent work that tells about class opposition and thinking about reality. This paper considers and analyzes the content, form and creation method of parasite, and discusses the continuous exploration and attempt of realistic film to image language under the demand of market and system, evolving into new aesthetic expression.

This study was conducted to elucidate the effect of mulching materials on growth characteristics, saponin contents and antioxidant activity of Platycodin grandiflorum Ridix roots for organic farming. Plastic film, sawdust and rice bran were treated by mulching with several different methods after transplanting P. grandiflorum Radix. In root length, when plastic film plot, sawdust plot and rice bran plot were treated, root length was recorded the highest scores (24.0~27.5 cm) in plastic film plot and sawdust plot. Root width was recorded the highest score (30.0 mm) in plastic film plot. Also, the number of fine-roots was the highest in plastic film plot (36.0). Fresh weight, which affects directly yield, was the highest in plastic film plot (130 g/plant). The contents of platycodin D3 and deapioplatycodin D were shown to 111.2 and 48.1 mg/100 g, the highest values were observed in sawdust plot. The total polyphenol and flavonoid contents were recorded the highest scores (11.0 and 8.6 mg/g, respectively) in plastic film plot. In this study we confirmed that there were differences among mulching materials in growth characteristics, saponin contents and antioxident activity of P. grandiflorum roots.

Purpose: To compare the visibility of the mandibular canal at the different radiographic methods such as conventional panoramic radiographs, Vimplant multi planar reformatting (MPR)-CT panoramic images, Vimplant MPR-CT paraxial images and film-based DentaScan MPR-CT images. Materials and Methods: Data of 11 mandibular dental implant patients, who had been planned treatment utilizing both panoramic and MPR-CT examination with DentaScan software (GE Medical systems, Milwaukee, USA), were used in this study. The archived axial CT data stored on CD-R discs were transferred to a personal computer with 17' LCD monitor. Paraxial and panoramic images were reconstructed using Vimplant software (CyberMed Inc., Seoul, Korea). Conventional panoramic radiographs, monitor-based Vimplant MPR-CT panoramic images, monitor-based Vimplant MPR-CT paraxial images, and film-based DentaScan MPR-CT images were evaluated for visibility of the mandibular canal at the mental foramen, 1 cm, 2 cm, and 3 cm posterior to mental foramen using the 4-point grading score. Results: Vimplant MPR-CT panoramic, paraxial, and DentaScan MPR-CT images revealed significantly clearer images than conventional panoramic radiographs. Particularly at the region 1 em posterior to mental foramen, conventional panoramic radiographs showed a markedly lower percentage of 'excellent' mandibular canal images than images produced by other modalites. Vimplant MPR-CT and DentaScan MPR-CT images did not show significant difference in visibility of the mandibular canal. Conclusion: The study results show that Vimplant and DentaScan MPR-CT imaging systems offer significantly better images of the mandibular canal than conventional panoramic radiograph.

This study comparatively analyzed the instrumentation and the voicing structure, which were shown in the film music titled "Star Wars-Main Title" by John Williams(1932~), with analytical technique that the writer mapped out, and aimed to discover the progression principle in orchestration based on the results. Also, it applied a functional part-division method that was classified and distributed into 3 functional parts according to auditory cognitive level as for each of functional elements such as the musical element. And, it made it pattern for the vertical structure and the voicing structure in musical instruments, which were distributed to each functional part based on this, and comparatively analyzed the standard point in a change which were shown according to progression of music, namely, the operating technique. As for the results of this study, first, each theme has specific instrumentation pattern. Unity was emphasized by consistently organizing those things in exposition, reprise, and recapitulation of each theme. To reinforce diversity, an attempt was made such as adding and reducing auxiliary instruments in the middle part and the rear part. Second, even in a change of instrumentation pattern by passage in accordance with a change in theme amid each part, the same instrumental group was organized in the middle part, thereby having maintained unity. Third, to strengthen diversity by clause, which is forming each theme, a continuous change in voicing pattern was created by adding or omitting a part. Fourth, the voicing concentration was maintained the structure of "thinness-thickness" in the whole musical piece. However, in part 2 that is repeated theme 3, diversity was pursued with a unique change of "thickness-thickness." Fifth, in part 4 that is indicated theme 4, the other diversity was intensified with the inverted range in the front part and the middle part. Accordingly, based on the conclusions that were indicated in this work, it is desired to be conducive to understanding the horizontal consideration and the progression principle of orchestration.

Polyethylene films contained 0, 10, 20, 30 and 40% of raw-ore powder(PERO) were prepared. The characteristics feature of the film and the powder were investigated in order to use packaging material for kimchi quality. Kimchi was packaged in the PERO bass md stored at 10$^{\circ}C$. The kimchi was examined for a pH, acidity, number of total microbe and lactic acid bacteria, E. coli, color values and sensory evaluation. The ore powder at 20$^{\circ}C$ produced infrared rays at 800-1100nm. The growth of E. coli md Staphylococcus aureus was extremely inhibited in the EMB and nutrient broth containing 10% of raw-ore powder but, that of lactobacillus plantarum and Leuconostoc mesenteriodes was slightly promoted in MRS broth containing 1%. The ripening by pH and acidity was slightly accelerated in kimchi in PERO bag(PERO-kimchi) compared to control kimchi but the maintenance of ripened-kimchi taste was prolonged in PERO-kimchi. The number of lactic acid bacteria of PERO-kimchi was more numerous than that of contol sample but that of E. coli wag exremely legs. The color L* values of PERO-kimchi was lower than control but a* and b* values were higher. Sensory evaluation of PERO-kimchi was higher score than control sample in crispness and overall taste about 10 to 20% of raw-ore contents for kimchi-packaging material was desirable.

For the study of the influence of kilovoltage and exposure time on radiographic density and contrast, we measured radiographic density of aluminum step wedge which composed of contiguous 8 steps wedges of 2-16㎜ thickness with densitometer. Aluminum step wedge was radiographed on Kodak ultraspeed DF-58 and Ektaspeed EP-21 film with range of 60-90 kVp and 5-60 impulse and subject contrast of aluminum step wedge with constant radiographic density and image contrast percentage without radiographic density was evaluated. Then we evaluated the film quality of teeth and their surrounding structure according to the change of kVp and exposure time by score rating method. The obtained results were as follows: 1. Radiographic density was related to the change of kilovoltage, especially in increased exposure time. 2. With constant radiographic density, subject contrast of thin aluminum step wedges was greater in low kilovolt age than high kilovoltage, but kilovolt age had not great influence on subject contrast of thick aluminum step wedge. On the other hand, radiographic density difference between 2mm and 16mm aluminum step wedge was decreased according to in- creasing kilovoltage. 3. Without constant radiographic density, image contrast percentage was decreased with increasing kilovoltage, but was not related with the change of exposure time. 4. Radiographic contrast of teeth and their surrounding structure which was taken with the range of 60-90 kVp and 6-30 impulse had not great influence on film quality.

Quality change of Kimchi packaged with Ny/PE, Ny/CPP (PPtray+Ny/CPP cover), Cryovac BK-1, BK-4, and PET/Al/PE film was observed during storage at $5^{\circ}C$ (97%RH) and $20^{\circ}C$ (76%RH). To evaluate quality change of Kimchi, gas composition of package, pH, acidity, color, growth of lactic acid bacteria, and sensory score were measured periodically. Regarding to gas composition of package, Kimchi packaged with PET/Al/PE showed higher oxygen concentration at the beginning of storage than the others; carbon dioxide concentration was almost 100% at the end of storage. Carbon dioxide concentration of Kimchi packaged with Cryovac BK-1 and BK-4 which has higher gas permeability than the others, was increased to a maximum and then decreased due to permeation of gas during storage; oxygen concentration was increased. Unlike Kimchi packaged with Ny/PE, Ny/CPP, and PET/Al/PE, package swelling was not observed in Kimchi packaged with Cryovac BK-1 and BK-4 during storage. Although pH change was not significant depending on the packaging material, Kimchi packaged with Cryovac BK-1 and BK-4 showed lower pH value and higher acidity than those of the others. Color change of Kimchi was different depending on the packaging material during storage. Difference of the growth of lactic acid bacteria and sensory evaluation were not significant among Kimchi packaged with different packaging material during storage at either temperature. In conclusion, the effect of packaging materials on the quality change of Kimchi was not significant; however, to prevent from swelling of packaged Kimchi which is one of the most serious problem during storage and distribution, might be avoided by using relatively high $CO_2$ permeable film than high gas barrier film.

To investigate effects of the surface finishing methods (A : conventional press stone, B : enclosing in polyethylene (PE) bag, C : press-tone wrapped with PE film and D : covered with Chinese cabbage leaves 4cm in thickness on Kimchi) on Kimchi quality, pH-values, redness, film forming yeast growth, hardness and sensory quality of Kimchi during storage (for 60 days, at $10{\pm}5^{\circ}C$) in glass vessel $(11{\times}30cm)$ were investigated. pH of the top layer of A, C and D sample were higher than the optimum pH (4.2) of Kimchi, film forming yeast occurred on the surface of Kimchi, color of top layer Kimchi juice was darkened, and panel score of freshness and firmness was significantly worse (p<0.01) than that of sample B. However, in the case of Kimchi stored in PE bag (B), film forming yeast were can't detected visually in the surface of Kimchi, pH values were low as good quality Kimchi, freshness and firmness panel scores and hardness were significantly better (p<0.01) than A, C and D, and redness of juice of top layer of B was also preserved clearly for 60 days. Accordingly among the four surface finishing methods, the B-method was most effective in preserving of y of Kimchi.
